Efficacy and safety of immunosuppressive therapies in the treatment of high-risk IgA nephropathy: A network meta-analysis.
IgA nephropathy (IgAN) is one of the significant contributing factors of end-stage renal disease (ESRD). It is reported that over half of patients with IgAN accompany multiple high-risk factors, which increase the risk of ESRD progression. Studies have shown that immunosuppressive agents were beneficial in high-risk IgAN, but the efficacy and safety have not been fully demonstrated yet. The present study aims to elucidate the efficacy of commonly used immunosuppressants in high-risk IgAN and their relative safety profiles via a network meta-analysis strategy.. Randomized controlled trials (RCTs) eligible for this network meta-analysis were included to evaluate the efficacy and safety of different immunosuppressants for high-risk IgAN. Main outcomes and measures include incidence of renal composite end point, the rate of total remission, adverse events, and proteinuria. Besides, subgroup analysis and cluster analysis were carried out.. This network meta-analysis of 37 RCTs involving 3012 participants found that Mycophenolate mofetil (MMF) combined with corticosteroids (CS) was superior to other interventions in end point events and proteinuria. Cyclosporine A (CsA) plus CS was the best option for clinical remission rate, and supportive care (SC) was the safest treatment. Cluster analysis showed that MMF+CS and Leflunomide (LEF)+CS were best protocols in efficacy and safety. Subgroup analysis indicated the best benefits of MMF were presented among the Asian population, and the benefits increased with the increase of follow-up duration. The effect of Cyclophosphamide (CTX) +CS on crescent IgAN was better than that of other risk factors. Moreover, the increasing follow-up duration was negatively associated with the effect.. MMF+CS and LEF+CS appear to serve as the best choice for treating high-risk IgAN than other immunosuppressive therapies.

Efficacy and safety of mycophenolate mofetil in the treatment for IgA nephropathy: a meta-analysis of randomized controlled trials.
IgA nephropathy is virtually known as the most common glomerulopathy to end-stage renal failure in the world. Mycophenolate mofetil is a selective immunosuppressant widely used in organ transplantation, yet its tolerance and effectiveness in IgAN is controversial.. This is a systematic review and random-effects meta-analysis, searching PubMed, Embase, Te Cochrane Library, Science Citation Index, Ovid evidence-based medicine, Chinese Biomedical Literature and Chinese Science and Technology Periodicals. Screen out randomized controlled trials on patients with biopsy-proven IgA nephropathy and analysis mycophenolate mofetil treatment regimens used for therapy of IgA nephropathy. Complete remission and partial remission, doubling of creatinine level, proteinuria, incidence of end-stage kidney disease, infection, Cushing syndrome, diabetes, hepatic dysfunction or gastrointestinal symptoms, neurologic or visual ambiguity, acne, and alopecia were observed.. Nine relevant trials were conducted with 587 patients enrolled. In Mycophenolate mofetil or plus medium/low-dose steroid comparing full-dose steroid alone or placebo, there was no significant difference. The risk of Cushing syndrome and diabetes had been significantly lowered with Mycophenolate mofetil-treated patients, while the risk of infection had been increased.. Mycophenolate mofetil therapy did not differ in reducing proteinuria and Scr in patients with IgAN who had persistent proteinuria, while having fewer Cushing syndrome and diabetes risk and more infection risk. However, larger randomized studies are needed to reveal these results.

Immunosuppressive agents for treating IgA nephropathy.
IgA nephropathy is the most common glomerulonephritis world-wide. IgA nephropathy causes end-stage kidney disease (ESKD) in 15% to 20% of affected patients within 10 years and in 30% to 40% of patients within 20 years from the onset of disease. This is an update of a Cochrane review first published in 2003 and updated in 2015.. To determine the benefits and harms of immunosuppression strategies for the treatment of IgA nephropathy.. We searched the Cochrane Kidney and Transplant Register of Studies up to 9 September 2019 through contact with the Information Specialist using search terms relevant to this review. Studies in the Register are identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Register (ICTRP) Search Portal and ClinicalTrials.gov.. We included randomised controlled trials (RCTs) and quasi-RCTs of treatment for IgA nephropathy in adults and children and that compared immunosuppressive agents with placebo, no treatment, or other immunosuppressive or non-immunosuppressive agents.. Two authors independently assessed study risk of bias and extracted data. Estimates of treatment effect were summarised using random effects meta-analysis. Treatment effects were expressed as relative risk (RR) and 95% confidence intervals (95% CI) for dichotomous outcomes and mean difference (MD) and 95% CI for continuous outcomes. Risks of bias were assessed using the Cochrane tool. Evidence certainty was evaluated using GRADE methodology.. Fifty-eight studies involving 3933 randomised participants were included. Six studies involving children were eligible. Disease characteristics (kidney function and level of proteinuria) were heterogeneous across studies. Studies evaluating steroid therapy generally included patients with protein excretion of 1 g/day or more. Risk of bias within the included studies was generally high or unclear for many of the assessed methodological domains. In patients with IgA nephropathy and proteinuria > 1 g/day, steroid therapy given for generally two to four months with a tapering course probably prevents the progression to ESKD compared to placebo or standard care (8 studies; 741 participants: RR 0.39, 95% CI 0.23 to 0.65; moderate certainty evidence). Steroid therapy may induce complete remission (4 studies, 305 participants: RR 1.76, 95% CI 1.03 to 3.01; low certainty evidence), prevent doubling of serum creatinine (SCr) (7 studies, 404 participants: RR 0.43, 95% CI 0.29 to 0.65; low certainty evidence), and may lower urinary protein excretion (10 studies, 705 participants: MD -0.58 g/24 h, 95% CI -0.84 to -0.33;low certainty evidence). Steroid therapy had uncertain effects on glomerular filtration rate (GFR), death, infection and malignancy. The risk of adverse events with steroid therapy was uncertain due to heterogeneity in the type of steroid treatment used and the rarity of events. Cytotoxic agents (azathioprine (AZA) or cyclophosphamide (CPA) alone or with concomitant steroid therapy had uncertain effects on ESKD (7 studies, 463 participants: RR 0.63, 95% CI 0.33 to 1.20; low certainty evidence), complete remission (5 studies; 381 participants: RR 1.47, 95% CI 0.94 to 2.30; very low certainty evidence), GFR (any measure), and protein excretion. Doubling of serum creatinine was not reported. Mycophenolate mofetil (MMF) had uncertain effects on the progression to ESKD, complete remission, doubling of SCr, GFR, protein excretion, infection, and malignancy. Death was not reported. Calcineurin inhibitors compared with placebo or standard care had uncertain effects on complete remission, SCr, GFR, protein excretion, infection, and malignancy. ESKD and death were not reported. Mizoribine administered with renin-angiotensin system inhibitor treatment had uncertain effects on progression to ESKD, complete remission, GFR, protein excretion, infection, and malignancy. Death and SCr were not reported. Leflunomide followed by a tapering course with oral prednisone com. In moderate certainty evidence, corticosteroid therapy probably prevents decline in GFR or doubling of SCr in adults and children with IgA nephropathy and proteinuria. Evidence for treatment effects of immunosuppressive agents on death, infection, and malignancy is generally sparse or low-quality. Steroid therapy has uncertain adverse effects due to a paucity of studies. Available studies are few, small, have high risk of bias and generally do not systematically identify treatment-related harms. Subgroup analyses to identify specific patient characteristics that might predict better response to therapy were not possible due to a lack of studies. There is no evidence that other immunosuppressive agents including CPA, AZA, or MMF improve clinical outcomes in IgA nephropathy.

The efficacy and safety of immunosuppressive therapies in the treatment of IgA nephropathy: A network meta-analysis.
Immunoglobulin A nephropathy (IgAN) is a common autoimmune glomerulonephritis that can result in end-stage renal disease (ESRD). Whether immunosuppressants are superior or equivalent to supportive care is still controversial. A network meta-analysis was conducted to compare the efficacy and safety of immunosuppressive treatment for IgAN. Medline, Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science, and EMBASE were searched on December 30, 2018. We used a random-effects model with a Bayesian approach to appraise both renal outcomes and serious adverse effects. Relative risks (RRs) with 95% confidence intervals (CIs) were calculated to present the relative effects. The ranking probabilities were calculated by the surface under the cumulative ranking curve (SUCRA). In total, 24 RCTs comprising 6 interventions were analyzed. Steroids significantly delayed the progression of renal deterioration with acceptable serious adverse effects, compared with supportive care (RR = 0.28, 95% CI = 0.13-0.51, SUCRA = 48.7%). AZA combined with steroids might be an alternative immunosuppressive therapy. Tacrolimus might decrease the proteinuria level (RR = 3.1, 95% CI = 1.2-9.4, SUCRA = 66.5%) but cannot improve renal function, and the side effects of tacrolimus should not be neglected. MMF and CYC showed no superiority in the treatment of IgAN. In summary, steroids might be recommended as the first-line immunosuppressive therapy for IgAN.

Treatment of IgA Nephropathy: Evolution Over Half a Century.
Fifty years into the original description of IgA nephropathy, there is still no specific therapy for this condition and general measures including blood pressure control with blockers of the renin-angiotensin-aldosterone system and salt restriction remain the cornerstone to slow disease progression. Although the paucity in treatment advances could be related to the disease's complex pathogenesis, which requires multiple hits, heterogeneity as reflected by diverse ethnic differences, and genetic predisposition and histopathologic variations, many nonspecific and immunomodulatory agents have been tested with variable degrees of success and tribulations. Here, we review the evolution of these different therapeutic approaches over time that culminated in the 2012 Kidney Disease: Improving Global Outcomes Clinical Practice Guideline for Glomerulonephritis that presently is being updated, and provide an appraisal of recent data on various forms of immunosuppressive agents. Finally, we discuss the theoretical basis of ongoing and upcoming clinical trials that are more pathway- or cell-type-specific as knowledge in disease mechanisms advances.

The Roles of Systemic Lupus Erythematosus and Immunoglobulin A Nephropathy in Glomerular Disease.
Two autoimmune diseases that can negatively affect kidney function are systemic lupus erythematosus (SLE) and immunoglobulin A (IgA) nephropathy. Autoimmune diseases occur when autoantibodies attack intrinsic tissue and generate inflammation in multiple body tissues, sometimes targeting specific organs. There is no cure for either SLE or IgA nephropathy, but both disorders may be medically managed.

Efficacy and safety of mycophenolate mofetil in patients with IgA nephropathy: an update meta-analysis.
The application of mycophenolate mofetil (MMF) in treating patients with immunoglobulin A nephropathy (IgAN) remains uncertain. This update meta-analysis was performed to re-evaluate the therapeutic potential of MMF in IgAN.. Articles were obtained by searching the electronic databases without language restriction. Randomized controlled trials studying the role of MMF in treating IgAN were collected. The quality of included studies was critically evaluated. Data analyses were performed by using RevMan 5.3 software.. A total of 297 articles were screened and eight articles were finally included. Among the eight randomized controlled trials, five and three were high quality and low quality, respectively. Both fixed-effect and random-effect model were used. Pooled results by combining all the eight studies suggested that IgAN patients in MMF group had a higher remission rate than that in control group. Compared to placebo or corticosteroid monotherapy, MMF monotherapy exerted a higher remission rate and side effect rate in both main analysis and subgroup analysis by human race. Compared to corticosteroid plus other immunosuppressive agent therapy, corticosteroid plus MMF therapy had a higher remission rate, lower serum creatinine doubling rate, progression to end-stage renal disease rate and side effects rate. Subgroup analysis by therapeutic regimen further confirmed these results between corticosteroid plus MMF therapy and corticosteroid plus cyclophosphamide therapy. Funnel-plot displayed a symmetrical figure, indicating no publication bias existed.. MMF has the potential in treatment of IgAN, especially for Asians. The evidence currently available shows that MMF monotherapy has a more efficacy but higher side effects when compared to placebo or corticosteroid monotherapy in treatment of Asians with IgAN. While MMF combined with corticosteroid regimen has a more efficacy and lower side effects when compared with corticosteroid plus cyclophosphamide regimen.

IgA Nephropathy.
IgA nephropathy (IgAN) is a leading cause of CKD and renal failure. Recent international collaborative efforts have led to important discoveries that have improved our understanding of some of the key steps involved in the immunopathogenesis of IgAN. Furthermore, establishment of multicenter networks has contributed to rigorous design and execution of clinical trials that have provided important insights regarding immunotherapy in IgAN. In this article, we review emerging developments in clinical and translational IgAN research and describe how these novel findings will influence future strategies to improve the outcome of patients with IgAN.

A lesson from kidney transplantation among identical twins: Case report and literature review.
There continues to be disagreement related to the appropriate therapeutic regimen to be used when the donor and the recipient in kidney transplant operations are identical twins. Here we present two cases of kidney transplantation between identical twins. Both recipients had end-stage renal disease (ESRD) caused by primary nephropathy. We also present information gleaned from a literature review of similar cases. The first recipient was a 26-year-old man who experienced biopsy-proven IgA nephropathy 10 months post-transplantation. Mycophenolate mofetil (MMF), angiotensin receptor blockers (ARBs), and steroids were used to reverse this pathologic condition. Till now, 76 months post-transplantation, the patient is stable, and the new kidney is functioning well. The second recipient was a 20-year-old woman who had hematuria and proteinuria 3 months post-transplantation, and crescent glomerulonephritis with mild to moderate interstitial injury was proven by biopsy 11 months postoperatively. This patient did not respond to various treatments and resumed hemodialysis 15 months post-transplantation. These case studies show that immunosuppressive therapy should be maintained in kidney transplant recipients who are identical twins with ESRD caused by initial nephropathy.

Diagnostic tests and treatment options in glomerular disease: 2014 update.
Glomerular diseases historically have been challenging disorders to comprehend and treat for patients and physicians alike. Kidney biopsy is the gold standard of diagnosis, but the link between pathophysiology and the histologic representation of kidney injury has remained elusive in many of these diseases. As a result, treatment of glomerular disease usually involves therapies that are not specific to disease pathogenesis, such as blockade of the renin-angiotensin-aldosterone system and various immunosuppression regimens. Recent research has resulted in greater insight into some glomerular diseases, leading to the hope that new diagnostic tests and treatments targeting disease-specific mechanisms are on the horizon. We review recent progress on the understanding, diagnosis, and treatment of 4 glomerular diseases: immunoglobulin A nephropathy, focal segmental glomerulosclerosis, the C3 glomerulopathies, and idiopathic membranous nephropathy.

Efficacy and safety of mycophenolate mofetil treatment in IgA nephropathy: a systematic review.
IgA nephropathy is the most common primary glomerular disease worldwide and also the most frequent cause of kidney failure. Mycophenolate mofetil (MMF) is a selective immunosuppressant widely used in many autoimmune diseases. However, the benefits and risks of MMF for the treatment of IgA nephropathy remain uncertain.. A systematic review and meta-analysis of randomized controlled trials (RCTs) was performed to assess the efficacy and safety of MMF in IgA nephropathy patients, using the statistical software Review Manager 5.1.. Eight RCTs involving 357 patients were identified and included in this review. Overall, no statistical difference was found in the therapeutic effect of MMF treatment compared with other therapies. MMF had no significant effects on reducing proteinuria or protecting renal function. However, subgroup analysis indicated that relatively short-term therapy (<18 months) might be beneficial in IgA nephropathy patients while longer term MMF use conferred no advantage. There was also no statistical difference between MMF and control groups in the incidence of side effects. When compared with other immunosuppressants, MMF was considered superior to cyclophosphamide in terms of better therapeutic effects and fewer adverse reactions, but no difference was found between MMF and leflunomide.. Our current evidence indicates that a relatively short course of MMF may be beneficial in treating IgA nephropathy. However, high-quality RCTs with large sample size as well as a well-designed study to evaluate the long-term effects of MMF are needed to further evaluate the efficacy and safety of MMF in this disease.

[Therapy in IgA nephropathy--when and how to do it].
IgA nephropathy is the most common primary glomerulonephritis worldwide. The clinical spectrum covers a wide range of features from minor urinary abnormalities (asymptomatic hematuria and mild proteinuria with normal renal function) to acute and chronic renal insufficiency. Ideally, the goal of treatment would be to correct any defects in IgA1 glycosylation and to modify mesangial deposition or removal of IgA1 deposits. There are only a few randomized controlled trials in IgA nephropathy; for this reason most treatment options are largely based on expert opinion. Authors discuss therapeutic options of different clinical pictures and the optimized renoprotective treatment of all IgA nephropathy patients.

Mycophenolate mofetil treatment for IgA nephropathy: a meta-analysis.
Worldwide, IgA nephropathy (IgAN) is the most common type of glomerulonephritis. Mycophenolate mofetil (MMF) is relatively selective for lymphocytes and inhibits antibody production by B cells more than other immunosuppressants. Several randomized controlled trials (RCTs) have analyzed the role of MMF in patients with IgAN. We conducted this meta-analysis of all available RCTs to ascertain the benefits and risks of MMF treatment in comparison with placebos or steroids in patients with IgAN.. The studies were identified by extended computer-based searches of the PubMed database (April, 2008) and the Cochrane Library, without language restriction. References in Medline-cited studies were reviewed to identify additional reports not indexed by Medline. RCTs comparing treatment of IgAN with mycophenolate against placebo or steroids were included in the analysis.. We identified 32 potentially relevant articles, but only 4 RCTs, which had enrolled a total of 168 patients, were included. Our meta-analysis demonstrated that MMF treatment did not have statistically significant effects in reducing proteinuria or protecting renal function in patients with IgAN.. The currently available evidence does not support the routine use of MMF in patients with IgAN. Larger international collaborations should be put in place to further address this issue.

Remission of proteinuria in primary glomerulonephritis: we know the goal but do we know the price?
Membranous nephropathy, focal segmental glomerulosclerosis and IgA nephropathy are the most commonly recognized types of primary glomerulonephritis that progress to end-stage renal disease. Persistent proteinuria is a major determinant of such progression. Reduction of proteinuria slows progression of renal disease and improves renal survival, but many of the agents used to reduce proteinuria carry a considerable risk of toxicity. The assessment of benefit versus risk of these medications can be further complicated by the temporal disconnect between the onset of benefit and of serious adverse events. In addition, relapses are common in these disorders and there is often a need for retreatment. Such retreatment might lead to repeated and/or prolonged drug exposure and to the oversight or underestimation of the cumulative dose of these agents because of the potentially extended interval between relapses. Consequently, it is very important to constantly review each patient's status and take into account their age, comorbid conditions and cumulative drug exposure when assessing treatment options. The potentially delayed development of adverse events also emphasizes the need for long-term surveillance of patients who receive immunosuppressive treatment for glomerular disease, often well beyond their drug exposure period and even when the treatment has been successful.

Mycophenolate mofetil in the treatment of IgA nephropathy: a systematic review.
The aim of this study was to determine the effectiveness of mycophenolate mofetil (MMF) in IgA nephropathy (IgAN).. A search through Cochrane Library, EMBASE and PubMed was carried out. Randomised controlled trials (RCTs), which compared MMF with conventional treatments, were identified. Patients' baseline, treatment strategies and study end-points were compared.. Four RCTs (168 patients) were selected. All patients had histologically-confirmed IgAN and proteinuria greater than 1 g/day. The follow-up duration ranged from 1.5 to 3.0 years. MMF was used at a titrated dose of 1-2 g/day. In the two trials with subjects having moderate to high risk for progressive disease, MMF did not demonstrate any significant difference in retarding the decline in renal function and proteinuria reduction. One trial concluded that there was a trend towards worse outcomes when MMF was used in moderately-advanced disease. Only one trial involving subjects with less advanced disease (reflected by a favourable histological grade) showed a significant decrease in proteinuria in the MMF-treated group. No serious adverse events occurred in all the four trials using MMF.. No benefit was seen in moderately-advanced IgAN treated with MMF. In a selected group of patients with less advanced disease, MMF was effective in proteinuria reduction. Larger randomised studies are needed to confirm or reject these results.

Mycophenolate mofetil in primary glomerulopathies.
Mycophenolate mofetil is an immunosuppressive agent that blocks purine biosynthesis, inhibits T and B-lymphocyte and mesangial proliferation. Mycophenolate mofetil is not nephrotoxic like calcineurin inhibitors and is widely used in solid-organ transplantation. Recently, mycophenolate mofetil has been introduced in the treatment of autoimmune diseases and primary glomerulopathies. This review analyzes the literature currently available on the treatment of primary glomerulopathies with mycophenolate mofetil. Encouraging results have been obtained in minimal change nephropathy where it may help to reduce the use of steroids in these patients who are often very young. The results obtained in medium and high risk patients with focal segmental glomerulonephritis and idiopathic membranous nephropathy were less encouraging. Conflicting results have been reported on IgA nephropathy in controlled trials. None of these studies attained level A evidence, meaning that randomized control trials of sufficient statistical significance are necessary to estimate the real effectiveness of mycophenolate mofetil in primary glomerulopathies.

Treatment of IgA nephropathy: corticosteroids, tonsillectomy, and mycophenolate mofetil.
Previous studies exploring the potential of glucocorticoid therapy on proteinuria and renal survival of patients with IgA nephropathy (IgAN) indicate that corticosteroid therapy is recommended if the patients show a moderate degree of proteinuria and their creatinine clearance exceeds 70 ml/min, although these studies, most of which are not prospective or randomized, have not provided conclusive results. Recently, Pozzi et al. demonstrated that treatment with glucocorticoids for 6 months significantly improved renal survival and proteinuria for 10 years of follow-up. A recent meta-analysis by Samuels et al. supports the use of corticosteroids in reducing proteinuria and preventing progression to end-stage renal disease. Increasing attention has been drawn to the role of tonsillectomy in the longterm prognosis of IgAN. The notion that tonsillectomy not only helps to prevent episodic macroscopic hematuria in the short-term but also gives long-term renal protection in IgAN is supported by two large retrospective studies from Japan. A study of 329 patients with IgAN by Hotta et al. found that tonsillectomy plus high-dose methylprednisolone was identified as one of the independent variables in predicting remission of clinical findings and lack of renal progression. Moreover, Xie et al. have reported that, for 20 years of follow-up, renal survival was significantly better in IgAN patients who underwent tonsillectomy than those who did not undergo the procedure. However, the role of tonsillectomy in the long-term prognosis of IgAN remains unclear, since it has not yet been tested in a controlled randomized trial. The role of mycophenolate mofetil (MMF) in IgAN has been examined in four major trials. Two prospective randomized studies report no benefit from MMF. The remaining two studies showed a greater reduction of proteinuria in patients treated with MMF compared to prednisone or placebo. In both studies, however, MMF did not effectively modify the progressive course of the disease. Thus, despite promising results in large randomized controlled trials in lupus nephritis, the evidence for the use of MMF in IgAN is inconclusive.

Use of mycophenolate mofetil in autoimmune and renal diseases.
Progress in understanding the pathogenesis and treatment of rheumatologic and glomerular diseases such as systemic lupus erythematosus and particularly lupus nephritis has been closely linked with the development of newer immunosuppressive agents. With improved patient survival following the institution of cyclophosphamide and corticosteroid therapy, longer-term management issues came to the forefront, especially how to decrease adverse effects of the immunosuppressive regimen. Many of the immunosuppressive regimens used in lupus patients were first established as efficacious and safe through their use in solid organ transplantation. Mycophenolate mofetil (MMF) is now widely used in the field of transplantation. Following anecdotal reports describing benefits of MMF in lupus and lupus nephritis patients, small studies and finally large randomized, controlled trials have established the use of MMF in these patients, particularly those with lupus nephritis. MMF use in other rheumatologic and renal diseases has been evaluated in only smaller studies and very few randomized controlled trials. Nevertheless, many studies currently are ongoing with this immunosuppressive agent. This article will review the published data and the experience of two major New York medical centers with the use of MMF in autoimmune and renal diseases.

Treatment of immunoglobulin A nephropathy.
In this review, therapeutic trials for treatment of IgA nephropathy (Berger's disease) are reviewed and discussed. No disease-specific therapy exists. For treatment of hypertensive patients, angiotensin converting enzyme (ACE) inhibitors are preferred. They also decrease proteinuria and probably slow disease progression. However, there are still no controlled data on the effectiveness of ACE-inhibitors in the absence of hypertension or proteinuria. Renewed enthusiasm for treatment with fish oil arose after the publication of a randomized controlled trial in 1994 and long-term follow-up data of the trial cohort in 1998. Corticoid therapy in IgA nephropathy has been advocated for patients with nephrotic syndrome or crescentic disease. A recent non-randomised trial with long-term follow-up suggests that, in the presence of moderate proteinuria, corticosteroids may ameliorate renal function if administered before the creatinine clearance has decreased below 70 ml/min. Preliminary data suggest that mycophenolate mofetil (MMF) may reduce the risk of clinically significant IgA nephropathy recurring in kidney allografts. Many other promising treatment approaches have been tested, but in most instances results are insufficient for unequivocal conclusions. Several randomized controlled clinical trials are currently testing prednisone, fish oil, ACE-inhibitors, cyclophosphamide, MMF and vitamin E. In the absence of a disease-specific treatment, control of hypertension, proteinuria and probably dyslipidemia are pivotal. Chronic or recurrent infection including ton-sillitis should be treated effectively. Control of daily protein intake to 0.7-0.8 g/kg body weight may retard disease progression.

Effectiveness of Mycophenolate Mofetil Among Patients With Progressive IgA Nephropathy: A Randomized Clinical Trial.
The role of mycophenolate mofetil (MMF) in management of immunoglobulin A nephropathy (IgAN) remains highly controversial.. To evaluate the efficacy and safety of MMF in patients with IgAN at high risk of kidney function loss.. This randomized clinical trial with open-label, blinded end-point design was conducted among adults with IgAN, proteinuria greater than 1.0 g/d, and estimated glomerular filtration rate (eGFR) greater than 30 and less than 60 mL/min/1.73m2 or with persistent hypertension from September 2013 to December 2015. During a 3-month run-in period, 238 patients received optimized supportive care (SC), including losartan. Patients with a urinary protein excretion rate of 0.75 g/d or greater despite of 3 months optimized SC were enrolled into the trial for 3 years. Survivors of the trial who did not receive dialysis or transplant were followed up after the trial for a median (IQR) of 60 (47-76) months. Data were analyzed from March through June 2022.. A total of 170 participants were randomized in a 1:1 ratio to receive MMF (initially, 1.5 g/d for 12 months, maintained at 0.75-1.0 g for at least 6 months) plus SC or SC alone.. The primary outcomes were (1) a composite of doubling of serum creatinine, end-stage kidney disease (dialysis, transplant, or kidney failure without receiving kidney replacement therapy), or death due to kidney or cardiovascular cause and (2) progression of chronic kidney disease.. Among 170 randomized patients (mean [SD] age 36.6 [9.4] years; 94 [55.3%] male patients), 85 patients received MMF with SC and 85 patients received SC alone. The mean (SD) eGFR was 50.1 (17.9) mL/min/1.73m2 and mean (SD) proteinuria level was 1.9 (1.7) g/d; 168 patients (98.8%) completed the trial, and 157 participants (92.4%) survived and did not receive dialysis or transplant. Primary composite outcome events occurred in 6 patients (7.1%) in the MMF group and 18 patients (21.2%) in the SC group (adjusted hazard ratio [aHR], 0.23; 95% CI, 0.09-0.63). Progression of chronic kidney disease occurred in 7 participants (8.2%) in the MMF group and 23 participants (27.1%) in the SC group (aHR, 0.23; 95% CI, 0.10-0.57). The effect of MMF treatment on primary outcomes was consistent across prespecified subgroups, with no significant interaction per subgroup. During posttrial follow-up, annual loss of eGFR accelerated after discontinuation of MMF; mean (SD) annual eGFR loss during the study period was 2.9 (1.0) mL/min/1.73m2 in the MMF group and 6.1 (1.2) mL/min/1.73m2 among 66 patients in the MMF group who discontinued MMF after the trial. Serious adverse events were not more frequent with MMF vs SC alone.. This study found that addition of MMF to SC compared with SC alone significantly reduced risk of disease progression among patients with progressive IgAN.. ClinicalTrials.gov Identifier: NCT01854814.

Mycophenolate Mofetil Combined With Prednisone Versus Full-Dose Prednisone in IgA Nephropathy With Active Proliferative Lesions: A Randomized Controlled Trial.
Observational studies suggest that patients with immunoglobulin A nephropathy (IgAN) with active proliferative lesions show a good response to immunosuppressive treatment.. Multicenter, prospective, randomized, controlled trial.. 176 patients with IgAN with active proliferative lesions (cellular and fibrocellular crescents, endocapillary hypercellularity, or necrosis), proteinuria with protein excretion ≥ 1.0g/24h, and estimated glomerular filtration rate > 30mL/min/1.73m. Mycophenolate mofetil (MMF) group: MMF, 1.5g/d, for 6 months and prednisone, 0.4 to 0.6mg/kg/d, for 2 months and then tapered by 20% per month for the next 4 months; prednisone group: prednisone, 0.8 to 1.0mg/kg/d, for 2 months and then tapered by 20% per month for the next 4 months. All patients were followed up for another 6 months.. The primary end point was complete remission rate at 6 and 12 months.. Not all participants were treated with renin-angiotensin system blockers, relatively short follow-up.. MMF plus prednisone versus full-dose prednisone did not differ in reducing proteinuria, but patients treated with the former had fewer adverse events in patients with IgAN with active proliferative lesions.

Randomized controlled trial of mycophenolate mofetil in children, adolescents, and adults with IgA nephropathy.
Previous randomized controlled trials evaluating the efficacy of mycophenolate mofetil (MMF) in patients with immunoglobulin A nephropathy (IgAN) have produced varying results.. Double-blind placebo-controlled randomized controlled trial.. 52 children, adolescents, and adults with biopsy-proven IgAN in 30 centers in the United States and Canada. Entry criteria: age older than 7 to younger than 70 years; urine protein-creatinine ratio (UPCR), ≥0.6g/g (males) or ≥0.8g/g (females); and estimated glomerular filtration rate ≥ 50mL/min/1.73m(2) (≥40mL/min/1.73m(2) if receiving angiotensin-converting enzyme inhibitor). Mean age, 32±12 (SD) years; 62% men; and 73% white.. Lisinopril (or losartan) plus a highly purified omega-3 fatty acid (Omacor [Pronova Biocare]) was given to 94 patients for 3 months; 52 of the patients with persistent UPCR≥0.6g/g (males) and ≥0.8g/g (females) were randomly assigned to MMF or placebo (target dose, 25-36mg/kg/d) in addition to lisinopril/losartan plus Omacor.. Change in UPCR after 6 and 12 months treatment with MMF/placebo and 12 months after the end of treatment.. UPCR measured on 24-hour urine samples. Glomerular filtration rate estimated with the Schwartz (age < 18 years) or Cockcroft-Gault (age ≥ 18 years) formula.. 44 patients completed 6 months of treatment with MMF (n=22) or placebo (n=22). The trial was terminated early at the recommendation of the Data Monitoring Committee because of the lack of benefit. No patient achieved a complete remission (UPCR<0.2g/g). Mean UPCRs at randomization and after 6 months were 1.45 (95% CI, 1.16-1.75) and 1.40 (95% CI, 1.09-1.70) for MMF and 1.41 (95% CI, 1.17-1.65) and 1.58 (95% CI, 1.13-2.04) for placebo, respectively. The mean difference in UPCR change between these groups (MMF minus placebo) was -0.22 (95% CI, -0.75 to 0.31; P=0.4). Adverse events were rare apart from nausea (MMF, 8.7%; placebo, 3.7%); one of these MMF patients withdrew.. Low patient enrollment and short follow-up.. MMF did not reduce proteinuria significantly in patients with IgAN who had persistent proteinuria after lisinopril/losartan plus Omacor.

Comparison of the therapeutic effects of leflunomide and mycophenolate mofetil in the treatment of immunoglobulin A nephropathy manifesting with nephrotic syndrome.
To evaluate the therapeutic effects and safety of a combination therapy of leflunomide (LEF) and prednisone for the treatment of immunoglobulin A (IgA) nephropathy manifesting with nephrotic syndrome.. 40 patients with IgA nephropathy manifesting with nephrotic syndrome were randomly divided into two groups. The treatment group was administered with a combination therapy of prednisone and LEF, and the control group with a combination therapy of prednisone and MMF. For the following comparison 24-h urinary protein excretion and the serum levels of albumin, cholesterol, and creatinine before and after the therapy were assessed.. In the treatment group, the medication was markedly effective in 5 cases and effective in 7 cases; the total efficacy rate was 60.0%. In the control group, the treatment was markedly effective in 5 cases and effective in 8 cases; the total efficacy rate was 65.0%. The IgA levels in both groups decreased after therapy. There were no significant differences between the results for the two groups (p > 0.05). The treatments were well tolerated in both groups.. LEF is a safe and effective drug for the treatment of IgA nephropathy manifesting with nephrotic syndrome.

Sequential immunosuppressive therapy in progressive IgA nephropathy.
Cyclophosphamide and high-dose steroids have been used as limited induction therapy in progressive IgA nephropathy (IgAN) to reduce the loss of renal function and proteinuria. We evaluated the effect of cyclophosphamide pulses (CyP) and mycophenolic acid (MPA) as sequential therapy on renal function in patients with progressive IgAN.. Twenty patients with progressive IgAN and advanced renal failure (median GFR 22 ml/min per 1.73 m2) and further disease activity (triangle downGFR -0.8 ml/min per month) after cyclophosphamide (CyP; n = 18) or steroid pulse therapy (n = 2) were treated with mycophenolate mofetil 1 g per day for a median of 27 months.. The monthly loss of renal function was significantly reduced in linear regression analysis from -2.4 ml/min before CyP to -0.12 ml/min with CyP/MPA (p = 0.0009). Estimated renal survival time was significantly prolonged by a median of 65 months (p = 0.0014). Proteinuria decreased significantly from 1.7 to 0.4 g/l during MPA treatment (p = 0.015). In Cox regression analysis, only proteinuria >1.0 g/l was an independent risk factor for doubling of creatinine during CyP/MPA treatment (p = 0.03).. A sequential therapy with CyP/MPA may arrest or slow down the loss of renal function and reduces proteinuria even in patients who passed the so called 'point of no return' with progressive IgAN.

Pharmacokinetics and pharmacodynamics of mycophenolic acid after enteric-coated mycophenolate versus mycophenolate mofetil in patients with progressive IgA nephritis.
Mycophenolic acid can be administered orally using mycophenolate mofetil or enteric-coated mycophenolate. In renal transplant patients on immunosuppressant combination therapy, the overall mycophenolic acid exposure after oral dosing with mycophenolate mofetil and enteric-coated mycophenolate is similar. This study compared pharmacokinetics and pharmacodynamics of mycophenolic acid after equivalent doses of enteric-coated mycophenolate (360 mg twice daily) or mycophenolate mofetil (500 mg twice daily) in 7 patients with progressive IgA nephritis (glomerular filtration rate 20-35 mL/min) using a randomized crossover design. The pharmacokinetics of mycophenolic acid concentrations and pharmacodynamics (using inosine 5'-monophosphate dehydrogenase activity as a bio-marker) were sequentially monitored for 12 hours. After enteric-coated mycophenolate treatment, the mycophenolic acid peak concentration (Cmax = 12.8 vs 6.0 microg/mL, P < .05) and the overall exposure were significantly higher (AUC = 60.9 vs 40.7 microg.h/mL, P < .05), and the apparent clearance was significantly lower (CL/F = 7.9 vs 10.7 L/h, P < .05) as compared to that after mycophenolate mofetil. Paradoxically, inosine 5'-monophosphate dehydrogenase activity was not significantly different. In conclusion, the steady-state mycophenolic acid exposure was higher during treatment with enteric-coated mycophenolate as compared to mycophenolate mofetil, which might be explained by more extensive enterohepatic recycling of mycophenolic acid after administration of enteric-coated mycophenolate, whereas inosine 5'-monophosphate dehydrogenase suppression was not different.

Mycophenolate mofetil alleviates persistent proteinuria in IgA nephropathy.
Mycophenolate mofetil (MMF) is increasingly used to treat primary glomerulopathies. Its effectiveness in IgA nephropathy (IgAN) remains unclear.. Forty IgAN patients with persistent proteinuria (>1 g/24 hours) despite conventional treatment with blockers of the renin-angiotensin system were randomized to receive MMF for 24 weeks (group 1) or continue conventional therapy (group 2), and followed for 72 weeks. The primary end point was reduction of proteinuria by 50% or more over entry level.. Sixteen patients (80%) in group 1 versus six patients (30%) in group 2 reached the primary end point (P= 0.0019). Time-averaged change in proteinuria showed a significant decline in group 1, while control subjects displayed a modest rise (P= 0.003). By 72 weeks, the mean proteinuria was 62.0 +/- 7.7% (P= 0.003) and 120.5 +/- 14.1% (P= 0.351) that of the corresponding baseline value in group 1 and group 2, respectively. There was concomitant increase in serum albumin and decrease in serum IgA levels in group 1 but not group 2 patients. Baseline histologic grades, blood pressure control, and the rates of change in serum creatinine and creatinine clearance were not different between the two groups. Normalization in binding of polymeric IgA to cultured mesangial cells and serum interleukin-6 (IL-6) levels, which sustained to study end, was observed in group 1 but not group 2 subjects.. In selected patients with IgAN, MMF is effective in lowering proteinuria and ameliorating some of the putative pathogenetic abnormalities.

Mycophenolate mofetil (MMF) vs placebo in patients with moderately advanced IgA nephropathy: a double-blind randomized controlled trial.
IgA nephropathy (IgAN) is the most common form of glomerulonephritis worldwide. Up to 40% progress to end-stage renal disease (ESRD) over 10-20 years. Currently, treatment is limited. We studied the use of mycophenolate mofetil (MMF) vs placebo in a group of North American IgAN patients at high risk for progressive disease.. Included were 32 patients aged 18-75 years from multiple centres who had their biopsies read at Columbia and who had at least 1 g of proteinuria per day plus at least two of the following risk factors: (i) male sex; (ii) hypertension >150/90 mmHg or requiring antihypertensive medications; (iii) creatinine clearance, measured by 24 h urine collection, <80 and >20 ml/min at time of enrolment; and (iv) presence of glomerulosclerosis or tubulointerstitial atrophy and fibrosis on renal biopsy. Patients were randomized to either 1 year of MMF, titrated up to a dose of 1000 mg bid, or placebo. Total follow-up was 2 years. All patients received angiotensin inhibition medication. The primary outcome was a 50% increase in baseline serum creatinine (SCr). Secondary outcomes were an increase of 0.5 mg/dl SCr, ESRD and a 50% reduction in proteinuria.. The mean baseline SCr was 2.4 mg/dl. No statistically significant differences were observed for any outcome. Five of 17 who received MMF vs two of 15 patients in the placebo group reached a 50% increase in SCr (P = 0.4). In both groups, all patients who reached the primary outcome also reached ESRD. Ten who received MMF vs seven who received placebo had a 0.5 mg/dl increase in SCr (P = 0.7) Only three MMF and two placebo patients had a 50% reduction in 24 h proteinuria. No serious adverse events occurred in either group.. No benefit was seen in patients who received MMF in this high risk group, probably reflecting the relatively advanced stage of disease of our population. We conclude that MMF is probably not effective in patients with IgAN who already have moderate renal insufficiency.

A randomized controlled trial of mycophenolate mofetil in patients with IgA nephropathy [ISRCTN62574616].
IgAN is the most common type of glomerulonephritis in the world. Between 15 and 40 percent of adults and children diagnosed with IgAN eventually progress to ESRD. Despite the need for effective treatment strategies, very few RCTs for IgAN have been performed. The most effective therapies for IgAN appear to be corticosteroids, ACEi, and FOS that contain a high concentration of omega 3 fatty acids. While ACEi and FOS are generally well tolerated with minimal side effects, the use of high dose steroids over a long course of therapy is often associated with significant morbidity.. The objective of the study is to test the hypothesis that treatment with the immunosuppressive agent, MMF, will lead to significant and sustained improvement in urinary protein excretion in patients with IgAN who have been pre-treated (and continue to be treated) with ACEi and FOS compared to a placebo control group of patients receiving comparable doses of ACEi and FOS without MMF.. After a three month treatment period with the ACEi, lisinopril and the FOS, Omacor, 100 (2 x 50) patients with IgAN and a urinary P/C ratio > or = 0.6 (males) and > or = 0.8 (females) and an estGFR > or = 40 ml/min/1.73 m2 will be randomized to treatment with either MMF or placebo for one year. All patients will be followed off study drug for a second year, but will continue treatment with lisinopril and Omacor for the two year duration of the study. The primary outcome measure of change in urine P/C ratio will be assessed at the end of years one and two.

Mycophenolate mofetil in IgA nephropathy: results of a 3-year prospective placebo-controlled randomized study.
Because humoral immunity is believed to play a pivotal role in the pathogenesis of IgA nephropathy (IgAN), a prospective placebo-controlled randomized study was started in patients with IgAN using mycophenolate mofetil (MMF).. A total of 34 patients with IgAN were treated with salt intake restriction, angiotensin-converting enzyme (ACE) inhibition and MMF 2 g per day (N= 21) or placebo (N= 13). After 36 months of follow-up clinical, biochemical, and radiologic data were analyzed using linear mixed models for longitudinal data and Kaplan-Meier survival analysis.. Therapy had to be stopped prematurely in five patients. Two patients (MMF group) evolved to end-stage renal disease (ESRD). There was no difference between groups in the percentage of patients with a decrease of 25% or more in the inulin clearance or with a serum creatinine increase of 50% or more over 3 years. There was also no significant difference between groups in annualized rate of change of serum creatinine, computed by linear regression analysis. No significant difference was noted between groups for inulin clearance, serum creatinine, proteinuria, blood pressure, or other parameters of renal function. Hemoglobin and C-reactive protein were significantly lower in the MMF group compared with the placebo group. As a function of time, a significant decline in both groups was noted of proteinuria, parenchymal thickness of the kidneys and C3d.. In patients with IgAN at risk for progressive disease, no beneficial effect of 3-year treatment with MMF 2 g per day could be demonstrated on renal function/outcome or proteinuria. However, larger randomized studies are needed to confirm or reject these results.

[A randomized control trial of mycophenolate mofeil treatment in severe IgA nephropathy].
To investigate the effectiveness safety and tolerance of mycophenolate mofeil(MMF) in severe IgA nephropathy and evaluate the dosage adjustment and course for clinical treatment.. 62 patients with IgA nephropathy diagnosed by renal biopsy as Lee's grade IV and V with urinary protein > 2.0 g/d were enrolled randomly in the trial. The initial dosage of MMF was 1.0 g/d (body weight < 50 kg) or 1.5 g/d (body weight > 50 kg). The dosage was reduced to 0.75 approximately 1.0 g/d after 6 months treatment, the maintaining dosage was 0.5 approximately 0.75 g/d after 12 months. The total course of treatment lasted at least 12 months. Another 31 patients matched with age gender and severity of renal damage were given prednisone orally (0.8mg(;)kg(;)d) (control group).Blood and urinary tests hepatic and renal function plasma albumin serum triglyceride and cholesterol 24 h protein excretion urinary NAG enzyme, creatinine clearance(Ccr) were performed before and 3 6 12 18 months after treatments in both groups 5 patients in MMF group received repeated renal biopsy.. (1) After 3 months treatment, decrease of urinary protein (1.9 g/24 h +/- 1.6 g/24 h vs 3.2 g/24 h +/- 1.7 g/24 h, P < 0.01) and improvement of plasma albumin (41 g/L +/- 6 g/L vs 37 g/L +/- 6 g/L, P < 0.01) were observed in MMF groups while in control group, no significant changes were found in uinary protein (2.3 g/24 h +/- 1.8 g/24 h vs 2.9 g/24 h +/- 1.5 g/24 h, P < 0.05) and plasma albumin (40 g/L +/- 6 g/L vs 37 g/L +/- 6 g/L, P < 0.05). After treatment for 6, 12 and 18 months, both group showed obvious alleviation of proteinuria and albumin. At the 12th and 18th month, the proteinuria in MMF group was significantly improved than that in control group (0.8 g/24 h +/- 0.8 g/24 h vs 1.4 g/24 h +/- 1.6 g/24 h and 0.6 g/24 h +/- 0.7 g/24 h vs 1.4 g/24 h +/- 1.3 g/24 h, P < 0.05 respectively). The remission rate and total effective rate of MMF group were higher than those of the control group (44.4% vs 19.1% and 88.9% vs 61.9%, P < 0.05 respectively). Patients were administered with MMF for 13.8 +/- 6.3 months (6 approximately 30 m). (2) Serum cholesterol and triglyceride were remarkably reduced after 6,12 and 18 months treatment in MMF group, no significant difference was found in control group(P < 0.05). (3) For the 6 patients with renal insufficiency in MMF group, MMF treatment was significantly effective in 1 patient, effective in 2 patients, not effective in 3 patients with an overall effective rate of 50%. For the 7 patients with renal insufficiency in control group, the treatment was significantly effective in 1 patient, effective in 1 patient, not effective in 5 patients and total effective rate is 28.6%. (4) 5 patients in MMF group received repeated renal biopsy after 7 approximately 12 months treatment (mean 9.8 +/- 2.3 m). The results showed that the interstitial lesions were alleviated. No special drug-induced renal damage was obtained. (5) Side effects: 3 patients in MMF group suffered from slight diarrhea, 1 patient herpes zoster, all of them got remission without drug withdrawal. 1 patient suffered nausea in the first weeks. No significant change was found in hepatic function (P > 0.05).. MMF is more effective in reducing proteinuria and serum lipid than the currently widespread use of prednisone therapy in IgA nephropathy patients with Lee SMK's grade IV approximately V and urinary protein > 2.0 g/d. Treatment with MMF associates with less adverse effect and good tolerance.

The steroid-sparing effects of a mycophenolate mofetil-based regimen in the management of immunoglobulin A nephropathy in patients with histologically active lesions: A comparison with a control cohort receiving conventional therapy.
While the use of different immunosuppressants has been investigated in immunoglobulin A nephropathy, further investigation is needed to assess the effect of a regimen of mycophenolate mofetil combined with a short course of glucocorticosteroids in the subset of patients with histologically active features. We compared the efficacy and safety of a combined regimen of mycophenolate mofetil and glucocorticosteroids to a conventional regimen of glucocorticosteroids alone in patients with immunoglobulin A nephropathy who have active lesions and major urinary abnormalities.. This retrospective study involved 30 immunoglobulin A nephropathy patients with active histological lesions, 15 of whom were treated with both mycophenolate mofetil 2 g/day for 6 months and 3 pulses of 15 mg/kg methylprednisolone, followed by a short tapering schedule of oral prednisone. The control group was made up of the remaining 15 clinically- and histologically-matched patients treated with glucocorticosteroids alone according to a validated schedule, i.e., 1 g of methylprednisolone given intravenously for 3 consecutive days, followed by oral prednisone 0.5 mg/kg every other day for 6 months. At diagnosis, all patients had urinary protein excretion > 1 g/24 h and microscopic hematuria.. At the end of the first year of follow-up (30 patients) and after 5 years (17 patients), there were no differences between the two groups in terms of urinary abnormalities and functional parameters. Both regimens achieved a statistically significant decrease in 24-h urinary protein excretion (p < 0.001) and a reduction of microscopic hematuria. However, the mycophenolate mofetil-based regimen allowed a cumulative sparing dose of 6 g of glucocorticosteroids.. In this single center study on immunoglobulin A nephropathy patients with active lesions and major urinary abnormalities and at increased risk of glucocorticosteroid-related complications, a mycophenolate mofetil-based regimen demonstrated similar outcomes in terms of complete response and relapse (at 1 and 5 years) compared to a conventional glucocorticosteroid-based protocol, while achieving a consistent reduction of glucocorticosteroid cumulative dose.

Treatment and outcome of IgA nephropathy in children from one single center experience.
There is no standard recommendation for IgA nephropathy treatment in children.. This is a retrospective study. From 2012 to 2020, newly diagnosed primary IgAN followed up for at least 1 year were enrolled. The correlation of MESTC scores and clinical index including proteinuria, gross hematuria and renal dysfunction was analyzed. Treatment and clinical response of 6 month, 1year and 3 year at follow up were also analyzed. Complete renal remission was calculated with Kaplan-Meier analysis.. The median follow up was 36 months, from 12 months to 87months in 40 IgAN children. Angiotensin-converting enzyme inhibitor (ACEI) was applied to all patients. 30% received ACEI alone; 15% received glucocorticoids; 37.5% received glucocorticoids plus cyclophosphamide, 17.5% received glucocorticoids plus mycophenolate mofetil. Individuals with diffuse mesangial hypercellularity (M1) were more likely to have nephrotic range proteinuria compared to patients with M0 (80% vs. 20%, P < 0.01). Complete renal remission at 6-month, 1-year and 3-year follow up is 50.25%, 70% and 87.5% respectively. Five-year complete renal remission calculated by Kaplan-Meier analysis is 58.4%. Although without significant difference, there is trend of better survival with complete renal remission in group of nephrotic range proteinuria onset. There is no severe adverse effect.. This study supports the use of glucocorticoids plus immunosuppressive in addition to ACEI in IgA nephrology pediatric patients with proteinuria. We suggest proactive immunosuppressive treatment in IgA nephropathy in children. This is from a single center in China as may not same results in other population.

Low-Dose Corticosteroid Combined With Mycophenolate Mofetil for IgA Nephropathy With Stage 3 or 4 CKD: A Retrospective Cohort Study.
This study assessed the long-term (10-year) tolerability and efficacy of a low-dose corticosteroid combined with mycophenolate mofetil (CS + MMF) in the treatment of immunoglobulin A nephropathy (IgAN) with stage 3/4 chronic kidney disease and proteinuria in clinical practice in China.. Of the 120 enrolled patients, 44, 25, and 51 were treated with USC, CS, and CS + MMF, respectively. The median follow-up time was 40.1 months (IQR, 29.1-67.8 months). The prevalences of the composite outcome were 63.6%, 56.0%, and 19.6%, respectively (P < 0.001). The cumulative 5-year renal function-preservation rates were 48.1%, 51.4%, and 83.7%. After adjustment for covariates, the prevalence of the composite outcome was significantly decreased with CS + MMF (HR = 0.094; 95% CI, 0.026-0.335; P < 0.001), but not with CS (HR = 0.749; 95% CI, 0.354-1.583; P = 0.449), compared with USC. However, 4 patients in the CS + MMF group died, of whom 3 had severe pneumonia.. CS + MMF may have more promising efficacy than USC or CS in renal-function preservation in patients with IgAN and chronic kidney disease in the Chinese population. However, attention should be paid to the increased risk for death due to severe pneumonia.

SARS Cov-2 infection in a renal-transplanted patient: A case report.
The clinical manifestation of COVID-19 can vary from an asymptomatic course to ARDS requiring invasive mechanical ventilation and extracorporeal membrane oxygenation. A kidney transplanted patient infected with SARS CoV-2 infection showed a mild disease despite immune suppression. It is possible that Immunosuppression can "be protective" as the cytokine storm is an important factor in the disease story. Despite the good outcome reported in the present case report, is remains of vital importance the solid organ transplant patients use precautions in order to avoid the infection.

Reduced Recurrence of Primary IgA Nephropathy in Kidney Transplant Recipients Receiving Everolimus With Corticosteroid: A Retrospective, Single-Center Study of 135 Transplant Patients.
Long-term kidney allograft survival remains a major clinical challenge. Recurrent glomerulonephritis disease, including recurrence of IgA nephropathy (IgAN), is a significant barrier to long-term kidney allograft survival. We performed a retrospective, observational study to evaluate the role of everolimus (EVR) in the risk of recurrent IgAN.. The study included data from 135 patients aged ≥16 years with biopsy-proven IgAN on native kidneys who underwent a kidney transplant (KT) between December 2002 and December 2018.. Patients who underwent de novo KT received mycophenolate mofetil (MMF) (n = 107) or EVR (n = 28). The mean recipient age in the MMF and EVR groups was 44.9 ± 13.7 and 41.1 ± 10.1, respectively. The median (interquartile range) follow-up period was 90.9 (64.9-115.3) and 21.2 (11.4-30.6) months, respectively (< .0001). All patients received continuous corticosteroid and tacrolimus therapy. The death-censored graft survival rate after KT and the recurrence-free survival rate did not differ significantly between the groups. Univariate and multivariate Cox regression analyses identified EVR for de novo KT as an independent predictive factor for recurrence-free survival (P = .024).. Our findings suggest that EVR-based regimens with tacrolimus and corticosteroid therapy for de novo KT reduce the recurrence of IgAN compared with MMF-based regimens with tacrolimus and corticosteroid therapy.

[Clinical effect of tacrolimus combined with glucocorticoid in the treatment of IgA nephropathy in children].
To study the clinical effect and safety of tacrolimus (TAC) combined with glucocorticoid (GC) versus mycophenolate mofetil (MMF) combined with GC in the treatment of primary IgA nephropathy (IgAN) in children.. A retrospective analysis was performed for the clinical data of children with primary IgAN confirmed by renal pathology between January 2012 and December 2017. These children were divided into TAC group and MMF group according to the treatment regimen. Their clinical data before treatment and at 1, 3, and 6 months of treatment were collected, and the remission status of IgAN and adverse reactions were compared between the two groups.. A total of 43 children who met the inclusion criteria were enrolled, with 15 children in the TAC group and 28 children in the MMF group. At 1 month of treatment, there was no significant difference in the remission status between the two groups (P>0.05). At 3 and 6 months of treatment, the TAC group had a significantly better remission status than the MMF group (P<0.05). At 1 month of treatment, the TAC group had higher serum albumin levels than the MMF group (P<0.05). Both groups had a significant increase in serum albumin levels at each time point after treatment (P<0.0083) and a significant increase in the glomerular filtration rate (GFR) at 3 and 6 months of treatment (P<0.0083). There was no significant difference in the overall incidence rate of adverse reactions between the two groups (P>0.05), but fungal infection was observed in one child from the TAC group.. TAC combined with GC can effectively reduce urinary protein in children with primary IgAN, and it has a better short-term clinical effect than MMF combined with GC, with good safety.

Value of the Oxford classification of IgA nephropathy in children with Henoch-Schönlein purpura nephritis.
The widely used International Study of Kidney Disease in Children (ISKDC) classification for Henoch-Schönlein purpura nephritis (HSPN) does not completely correlate with the clinical presentation and long-term prognosis of this disease. Primary IgA nephropathy (IgAN) and HSPN share common features; thus, the Oxford classification of IgAN might be useful in predicting the long-term outcomes of HSPN. However, its value has not been confirmed in children with HSPN.. We selected children with HSPN diagnosed between 2003 and 2015, and reclassified their renal biopsies according to the Oxford classification scoring system. The primary outcome was impaired renal function, and remission of proteinuria and clinical remission were secondary outcomes.. We included 104 patients (58 males, 46 females) with a median age of 10 (4-17) years. Mesangial hypercellularity (M1) was strongly associated with proteinuria, and tubular atrophy/interstitial fibrosis (T1&2) and C2 (with crescents in > 25% of glomeruli) were associated with reduced estimated glomerular filtration rate (eGFR) at the time of biopsy. Patients with M1, endocapillary proliferation (E1), segmental glomerulosclerosis (S1), and crescents (C1&2) were more likely to have been treated with high-dose methylprednisolone. At univariate time-dependent analyses, S1 was strongly associated with the primary outcome (p = 0.025), whereas T1&2 was significantly negatively associated with proteinuria remission (p = 0.035) and clinical remission (p = 0.038).. Our findings suggest that the Oxford classification is valid for children with HSPN. S and T lesions, which are ignored in the ISKDC classification, can be used to assess renal outcomes of HSPN, and such assessments are not affected by currently available treatments. The value of M, E and C lesions in predicting response to therapy and renal outcome warrants further study.

Mycophenolate mofetil therapy in immunoglobulin A nephropathy: histological changes after treatment.
Endocapillary hypercellularity independently predicts renal outcome in immunoglobulin A nephropathy (IgAN). Mycophenolate mofetil (MMF) treatment is offered to patients presenting to the Imperial College Renal and Transplant Centre with IgAN and histological evidence of endocapillary hypercellularity. Clinical trials of MMF in IgAN have been inconclusive and have been limited by a lack of specific histological inclusion and exclusion criteria when recruiting patients. Evidence of histological improvement following MMF treatment would support its therapeutic use. We therefore reviewed histological changes after MMF therapy in a cohort of IgAN patients.. Eighteen IgAN patients with native renal biopsies before and after repeated MMF treatment were identified. Patients were excluded if they had received any other immunosuppressive therapy, including corticosteroids. On the basis of the Oxford Classification of IgAN, we reviewed histological changes after MMF treatment.. Nine patients (50%) were male. At diagnostic renal biopsy, the median age was 35 years [interquartile range (IQR) 30-41], serum creatinine was 97 µmol/L (IQR 79-153) and urine protein creatinine ratio (UPCR) was 146 mg/mmol (IQR 98-212). The median time between biopsies was 24 months (range 9-41). Following MMF treatment, repeat biopsy demonstrated statistically significant improvement in the mean percentage of glomeruli showing endocapillary hypercellularity and cellular/fibrocellular crescents. There was no change in mesangial hypercellularity, segmental sclerosis or tubular atrophy scores. Mesangial IgA deposition was also significantly reduced. Histopathological improvement persisted after the cessation of MMF therapy, suggesting that 2 years of treatment is adequate for benefit. The median serum creatinine remained stable at 3 years follow-up at 104 µmol/L (IQR 79-147).. MMF treatment is associated with histopathological improvement in IgAN.

Mycophenolate Mofetil: A Possible Alternative Treatment for IgA Nephropathy.
IgA nephropathy (IgAN) is the most common primary glomerulonephritis in developed countries and a leading cause of chronic kidney disease. IgAN is a mesangial proliferative glomerulonephritis characterized by diffuse mesangial deposition of IgA, often accompanied by the deposition of IgG and the C3 component of complement in a similar distribution. This condition is in most cases oligosymptomatic, often discovered coincidentally. Currently, there is no specific treatment available for IgAN and the use of immunosuppression therapy is debated. Due to immune-mediated pathogenic nature of IgAN, therapy with mycophenolate mofetil (MMF), a potent immunosuppressive agent, could be effective in patients at risk for progressive disease. In this paper, we discuss the case of an IgAN patient treated with MMF at our center, followed by a review of the literature and our previous experience on the potential renoprotective effects of MMF in IgAN patients with different clinical presentation, despite adequate angiotensin blockade and steroid therapy.

Sequential therapy with cyclophosphamide and mycophenolic acid in patients with progressive immunoglobulin A nephropathy: a long-term follow-up.
In progressive immunoglobulin (Ig)A nephropathy (IgAN), cyclophosphamide pulse therapy (CyP), high-dose intravenous immunoglobulins (IVIg) and mycophenolic acid (MPA) have been used to stop progressive loss of renal function, but disease progression may occur after the end of the initial treatment. Here, we report the long-term follow-up of patients with progressive IgAN with MPA as maintenance therapy after CyP (CyP-MPA). In a median observation time of 6·2 years, we analysed the slopes of the loss of renal function of 47 patients with biopsy-proven IgAN and treated with CyP. Thirty-one patients with further progression were treated with MPA maintenance for a median time of 5·2 years. Follow-up was compared with symptomatic therapy and IVIg as historically matched control groups. Median loss of renal function was reduced significantly from 0·9 ml/min to 0·1 ml/min per month with CyP (P < 0·05), and with MPA in patients with a relapse from -0·4 ml/min to -0·1 ml/min per month (P < 0·05) until the end of the study. Proteinuria decreased significantly from 1·6 g/l to 1·0 g/l after CyP, and during MPA treatment to 0·6 g/l (P = 0·001 Friedman test). Median renal survival time was in patients with CyP 10·5 years (range = 3·2-17·8), with CyP-MPA 10·7 years (range = 8·3-13·1), with IVIg 4·7 years (range = 2·6-6·6), and in untreated patients 1·2 years (range = 0·8-1·6; log-rank test P < 0·01). In patients with progressive IgAN, our long-term follow-up observation indicates that sequential CyP-MPA therapy maintains renal survival significantly.

Effect of Immunosuppressive Drugs on the Changes of Serum Galactose-Deficient IgA1 in Patients with IgA Nephropathy.
Galactose-deficient IgA1 (Gd-IgA1) and IgA-IgG complexes are known to play an important role in the pathogenesis of IgA nephropathy (IgAN). We aimed therefore to determine the impact of immunosuppression on the serum levels of Gd-IgA1, total IgA1 and IgA-IgG complexes in IgAN patients. In a retrospective study, serum samples from IgAN patients collected before transplantation (t0) and at 3- and 6-month posttransplant (t3 & t6) were used to measure the levels of Gd-IgA1, total IgA1 and IgA-IgG complexes. The area under the curves (AUC) of immunosuppressants was calculated by the plot of plasma trough level or dosage of each immunosuppressant versus time and was interpreted as the extent of drug exposure. Thirty-six out of 64 IgAN patients, who underwent kidney transplantation between 2005 and 2012, were enrolled. From t0 to t3, serum Gd-IgA1 and total IgA1 decreased significantly (24.7 AU (18.6-36.1) to 17.2 (13.1-29.5) (p<0.0001); 4.1 mg/ml (3.6-5.1) to 3.4 (3.0-4.1) (p = 0.0005)), whereas IgA-IgG complexes remained similar. From t3 to t6, Gd-IgA1 and IgA-IgG complexes significantly increased (17.2 AU (13.1-29.5) to 23.9 (16.8-32.0) (p = 0.0143); OD 0.16 (0.06-0.31) to 0.26 (0.14-0.35) (p = 0.0242)), while total IgA1 remained similar. According to median regression analysis, AUC of prednisone t0-6 was significantly associated with the decrease of Gd-IgA1 t0-6 (P = 0.01) and IgA1 t0-6 (p = 0.002), whereas AUC of tacrolimus t0-6 was associated with the decrease of IgA1 t0-6 (p = 0.02). AUC of prednisone t0-3 was associated with the decrease of IgA-IgG complexes t0-3 (p = 0.0036). The association of AUC prednisone t0-6 with Gd-IgA1 t0-6 remained highly significant after adjustment for other immunosuppressants (p = 0.0036). Serum levels of Gd-IgA1, total IgA1 and IgA-IgG in patients with IgAN vary according to the changing degrees of immunosuppression. The exposure to prednisone most clearly influenced the serum levels of Gd-IgA1.

Severe pneumonia in mycophenolate mofetil combined with low-dose corticosteroids-treated patients with immunoglobulin A nephropathy.
The tolerance of mycophenolate mofetil (MMF; Shanghai Roche, China) in Lee Classes III, IV, and V immunoglobulin A nephropathy (IgAN) remains unclear. This article reports nine cases of severe pneumonia (SP), including pneumocystis pneumonia (PCP) and cytomegalovirus (CMV) pneumonia, and its risk factors in MMF plus low-dose corticosteroid-treated patients with Lee Classes III, IV, and V IgAN. Fifty-three patients with IgAN were included in this single-center study. The treatment regimen was MMF (1-1.5 g/d) plus low-dose corticosteroids (0.5 mg/kg/d). SP was defined as diffuse bilateral lung infiltrate with respiratory failure. PCP was diagnosed by detecting the organisms in the sputum and bronchoalveolar lavage. CMV infection was diagnosed through serum screening for CMV-IgG and IgM antibodies and CMV-DNA testing by a real-time polymerase chain reaction assay. The risk factors of SP were analyzed. Nine cases (16.9%) of SP occurred in this study. All SP developed at approximately the 10(th)-14(th) week after the initiation of the regimen: PCP was diagnosed in four cases and CMV infection in two cases. Renal function impairing was more serious in patients with SP than in those without SP, as evidenced by estimated glomerular filtration rate (p = 0.019) and serum creatinine level (p = 0.016). Six of the nine SPs occurred in MMP plus low-dose methylprednisolone group, which was statistically higher than that in the MMF plus low-dose prednisone group (p = 0.000). The incidence of SP in this study was 16.9%. Chronically impaired renal function and the use of methylprednisolone may be the risk factors for SP.

Mycophenolate mofetil therapy for steroid-resistant IgA nephropathy with the nephrotic syndrome in children.
Immunoglobulin A nephropathy (IgAN) presents as nephrotic syndrome (NS) relatively rarely, and the current treatment experience of IgAN patients with NS is mostly with adults. The objective of our study was to investigate the efficacy of corticosteroids and mycophenolate mofetil (MMF) in treating childhood immunoglobulin A nephropathy (IgAN) with nephrotic syndrome.. A total of 58 children (39 boys and 19 girls) diagnosed with nephrotic syndrome and primary IgAN were enrolled in the study. All the patients were administered prednisone 2 mg/kg per day for 8 weeks. Steroid-resistant patients were treated with the combined use of MMF (dose of 20 ~ 30 mg/kg per day) and prednisone for 6-12 months. The prednisone dose was reduced stepwise during the combined treatment.. Of the 58 children, 14 were steroid-sensitive (M, S, and T variants of the Oxford classification were 0 in most children), and 44 cases who presented serious pathological damage to the kidney were steroid-resistant. The estimated glomerular filtration rate (eGFR) of the steroid-resistant children (86.69 ± 26.85 ml/min/1.73 m(2)) was significantly lower (P < 0.05) than that of the steroid-sensitive children (106.89 ± 26.94 ml/min/1.73 m(2)). After 4 months of combined MMF treatment in 33 steroid-resistant children, complete remission of proteinuria was found in 21 cases, partial remission of proteinuria in 6 cases, and no response was found in 6 cases. Except for the T variant, other variants of the Oxford classification, including M, E, and S morphological variables, was not significantly different among patients complete remission, those with partial remission, and those with no response. The eGFR of children with complete remission of proteinuria (100.04 ± 18.47 ml/min/1.73 m(2)), that of those with partial remission (92.24 ± 27.63 ml/min/1.73 m(2)), and that of those with no response (72.17 ± 27.55 ml/min/1.73 m(2)) were significantly different (P < 0.05).. Corticosteroid therapy showed satisfactory efficacy in IgAN children with nephrotic syndrome and slight pathological damage. The effect of MMF was good for steroid-resistant IgAN children, but poor for those with tubular atrophy/interstitial fibrosis and renal function impairment.

Treatment of severe IgA nephropathy: mycophenolate mofetil/prednisone compared to cyclophosphamide/prednisone.
To compare the efficacy of mycophenolate mofetil (MMF)/prednisone to cyclophosphamide (CYC)/prednisone in the treatment of severe IgA nephropathy.. Patients (n = 84) with severe IgA nephropathy received either MMF/prednisone (MMF group) or CYC/prednisone (CYC group). The MMF induction dose was 1.5 g/d for 6 months and the maintenance dose was 0.75 - 1.0 g/day for 12 months. The CYC induction dose was 0.8 - 1.0 g/month for 6 months and the maintenance dose was 0.8 - 1.0 g/3 months for 12 months. Laboratory tests, clinical remission rate and side effects were investigated.. After 18 months of treatment, the total effective rate in the MMF group was significantly higher than that of the CYC group. Patients' 24-hour urinary protein excretion in the MMF group was lower than the CYC group. Patients' plasma albumin and total protein in the MMF group was higher than the CYC group. MMF and prednisone reduced serum lipids, while in the CYC group serum lipids remained unchanged. There was also a lower incidence of adverse effects in the MMF group (4.76%) than in the CYC group (26.2%).. Combination therapy with MMF and prednisone for severe IgA nephropathy achieved a higher remission rate compared to treatment with CYC and prednisone. This therapy also reduced the 24-hour urinary protein and serum lipids while increasing plasma albumin and improving renal function. The incidence of adverse effects was significantly lower in the MMF group compared to the CYC group. *These authors have contributed equally to this work.

Retrospective study of mycophenolate mofetil treatment in IgA nephropathy with proliferative pathological phenotype.
Mycophenolate mofetil (MMF) and cyclophosphamide (CTX) are widely used in treating various kidney diseases. However, whether they are effective and which one is better for treating IgA nephropathy patients with proliferative pathological phenotype in renal diseases, such as endocapillary proliferation, cellular crescents, and/or capillary loops fibrinoid necrosis is still unknown. We, therefore, initiated a study to compare the effects of MMF and CTX in treating IgA nephropathy with the above pathological lesions.. One hundred and nineteen patients with IgA nephropathy who had at least one of the three aforementioned lesions were enrolled. All patients were treated with prednisone; 48 patients received prednisone only (Pred group), 40 received MMF and prednisone (MMF + Pred group), and 31 were treated with CTX and prednisone (CTX + Pred group). The median time of follow-up was 30 months (maximum: 96 months). The primary endpoint was defined as renal survival. The incidence of remission of proteinuria was the secondary endpoint.. Serum creatinine in all groups declined significantly at different follow-up times (P = 0.002), and the differences among the three groups were significant (P < 0.001). At 24 months of follow-up, the decline rates were 12.35%, 32.95%, and 24.14% in the Pred, MMF + Pred, and CTX + Pred groups respectively. For urine protein excretion, the decline rates were 49.12% (Pred), 73.67% (MMF + Pred), and 63.53% (CTX + Pred) respectively at 24 months of follow-up. The differences among the three groups were not significant (P = 0.714). Renal survival (the primary endpoint) was significantly different (P = 0.027); however, the sencondary endpoint was similar for all the three groups (P = 0.100).. For IgA nephropathy patients with endocapillary proliferation, cellular crescents, and/or fibrinoid necrosis of capillary loops, prednisone combined with MMF was more effective in lowering the serum creatinine than with CTX. Combined MMF and prednisone treatment led to a better renal survival compared to that of prednisone with CTX.

Mycophenolic acid reverses IgA1 aberrant glycosylation through up-regulating Cosmc expression in IgA nephropathy.
Impaired core I β3-Gal-T-specific molecular chaperone (Cosmc) expression-caused IgA1 aberrant O-glycosylation is one of the main pathogeneses of IgA nephropathy (IgAN).This study tried to elucidate whether mycophenolic acid (MPA) could up-regulate Cosmc expression of peripheral lymphocytes in IgAN patients and reverse the dys-O-glycosylation.. Peripheral lymphocytes of eighteen IgAN patients and twelve normal controls were isolated and cultured for 3-7 days with or without lipopolysaccharide (LPS) and MPA. Cosmc mRNA and protein expression levels were measured by real-time RT-PCR and western blot. IgA1 and O-glycosylation level were determined by enzyme-linked immunosorbent assay (ELISA) and VV lectin-binding test. Correlation analysis was performed between Cosmc expression levels and IgA1 O-glycosylation level.. Cosmc mRNA expression and IgA1 O-glycosylation level in IgAN patients were significantly lower than normal controls. Treatment of LPS could obviously inhibit the Cosmc expression and increase the IgA1 secretion in peripheral lymphocytes of IgAN patients, which resulted in a significantly increase in IgA1 aberrant glycosylation level. Addition of MPA could significantly increase the Cosmc expression level along with a decrease in IgA1 secretion, leading to a reverse of aberrant glycosylation. A significant positive correlation between the Cosmc expression and IgA1 O-glycosylation level was noticed.. MPA can up-regulate the Cosmc expression and reverse the IgA1 aberrant O-glycosylation level in peripheral lymphocytes of IgAN patients, which might be the underlying mechanism of mycophenolate mofetil (MMF) therapy used in treating IgAN.

[Immunoglobulin A nephropaty: clinical practice guidelines].
Immunoglobulin A nephropathy (N.IgA) is the world most common glomerular disease; 15-50% of patients develop loss of renal function in 10-20 years, and the rest remission or mild proteinuria/ hematuria. The optimal treatment is uncertain. Our aim was to develop evidence-based recommendations through research in Medline, Embasse, Lilacs and Cochrane Central Register of Controlled Trials. The study-quality was independently assessed by the reviewers following the Cochrane Renal Group checklist: randomization, blinding, intention-to-treat analysis and follow-up period. Levels of evidence and grades of recommendation were assigned according to Center for Evidence-Based Medicine, Oxford. Two approaches were considered: Immunosuppressive therapy (corticosteroids, cytostatics, cyclosporine A, mycophenolate-mofetil): Level I a, grade A. -Combined suppressive therapy in adults. Corticosteroids plus cytotoxics drugs (cyclophosphamide/azathioprine): Level II b, grade B. In children with severe IgA nephropathy: Level II b, grade D. Cyclosporine and mycophenolate- mophetil: Level II b, grade C. Cyclosporine and mycophenolate-mophetil: Level ll b, grade C. -Non immunosuppressive therapy: reninangiotensin converting enzyme inhibitors (ACEI) and/or angiotensin II receptor blockers (ARB), fish oil, statins, antiplatelets and tonsillectomy. ACEI and/or ARB, in patients with proteinuria ≥ 1 g: Level I a, grade A. In children with moderate proteinuria: ACEI and/or ARB with close monitoring of renal function and serum potassium level: Level II b, grade B. Antiplatelet as supportive treatment: Level I a, grade C. Fish oil in addition to ACEI or ARB in patients with mild histological lesions: Level II b, grade B (Not in children). Statins: no evidence to recommend these drugs in children. In patients > 5 years with nephrotic syndrome and hyper-cholesterolemia, use statins with close monitoring of serum creatine-kinase. There is no evidence to recommend tonsillectomy.

Since the efficacy of mycophenolate mofetil (MMF) to treat immunoglobulin A (IgA) nephropathy is controversial, we extended our original study by following 40 Chinese patients with established IgA nephropathy for 6 years. All patients were maintained on their angiotensin blockade medication and half were randomized to receive MMF for 6 months. After 6 years, 11 patients required dialysis (2 from the MMF and 9 from the control group). Significantly, only 3 treated (as compared to 10 control) patients reached the composite end point of serum creatinine doubling or end-stage renal disease. Linear regression showed the annualized decline in the estimated glomerular filtration rate was significantly less in the MMF-treated group. Urinary protein excretion and the albumin-to-creatinine ratio were lower with MMF treatment during the first 24 months, beyond which there was no difference between groups. Multivariable Cox regression analysis showed that the baseline estimated glomerular filtration rate and proteinuria, and change in the urine albumin-to-creatinine ratio at 1 year to be important predictors of progression to end-stage renal disease. We found that among Chinese patients with IgA nephropathy who had mild histologic lesions and persistent proteinuria despite maximal angiotensin blockade, MMF treatment may result in transient and partial remission of proteinuria in the short-term and renoprotection in the long-term.

Sirolimus-induced drug fever in a renal transplant patient: a case report.
Herein we have described the case of a male renal transplant recipient who developed drug fever apparently related to sirolimus. He had been stable under an immunosuppressive regimen of tacrolimus and mycophenolate mofetil, but developed acute cellular rejection at 5 years after transplantation due to noncompliance. Renal biopsy showed marked interstitial fibrosis, and immunosuppression was switched from mycophenolate to sirolimus, maintaining low tacrolimus levels. One month later he was admitted to our hospital for investigation of intermittently high fever, fatigue, myalgias, and diarrhea. Physical examination was unremarkable and drug levels were not increased. Lactic dehydrogenase and C-reactive protein were increased. The blood cell count and chest radiographic findings were normal. After extensive cultures, he was started on broad-spectrum antibiotics. Inflammatory markers and fever worsened, but diarrhea resolved. All serologic and imaging tests excluded infection, immune-mediated diseases, and malignancy. After 12 days antibiotics were stopped as no clinical improvement was achieved. Drug fever was suspected; sirolimus was replaced by mycophenolate mofetil. Fever and other symptoms disappeared after 24 hours; inflammatory markers normalized in a few days. After 1 month the patient was in good health with stable renal function. Although infrequent, the recognition of drug fever as a potential side effect of sirolimus may avoid unnecessary invasive diagnostic procedures. Nevertheless, exclusion of other common causes of fever is essential.

Mycophenolate mofetil treatment of crescentic Henoch-Schönlein nephritis with IgA depositions.
Mycophenolate mofetil (MMF) is considered to be a promising therapeutic agent in primary glomerulonephritis but there are no data on the use of MMF in Henoch-Schönlein nephritis (HSN). Herein we report the first adult crescentic HSN patient in whom long-term complete remission was achieved after MMF therapy.

Delayed severe pneumonia in mycophenolate mofetil-treated patients with IgA nephropathy.
Mycophenolate mofetil (MMF), a relatively new immunosuppressant, is widely used in the field of transplantation and also for autoimmune diseases with good tolerance. It has been reported that MMF possesses potent activity against pneumocystis pneumonia (PCP). This study investigated the effects of this treatment on the occurrence of severe pneumonia (SP) including PCP and its risk factors.. This was a retrospective cohort study. Of 850 IgA nephropathy (IgAN) patients that were followed up in our renal centre, 32 received MMF (1-1.5 g/day) and 47 were treated with cyclophosphamide (CTX; 50-100 mg/day). All the patients also received prednisone. SP was defined as diffuse bilateral lung infiltrate with respiratory failure, and PCP was diagnosed by detecting organisms in sputum and bronchoalveolar lavage.. Patients given MMF or CTX did not differ in their distribution of age, sex, renal function or prednisone dosage. However, 6 of the 32 patients developed SP around the third month after the initiation of MMF administration: 3 were diagnosed with PCP, 2 with suspected PCP and in the other PCP could not be excluded. SP did not occur in patients treated with CTX. Most SP cases (five of six) presented with abrupt onset and rapidly progressed to respiratory failure, from which four died. The deterioration of renal function was strongly associated with the occurrence of SP. Six patients (6 of 16) with chronic renal function impairment (eGFR < 60 ml/min/1.73 m(2)) developed SP while none of the patients with eGFR > 60 ml/min/1.73 m(2) did. Absolute lymphocyte counts decreased significantly in patients with eGFR < 60 ml/min/1.73 m(2) after 3 months of MMF treatment compared to the counts before MMF was initiated (1.71 +/- 0.23 versus 2.43 +/- 0.17 x 10(9)/l, P = 0.04). This effect was more pronounced in patients with SP, which had significantly lower counts than patients without SP (0.22 +/- 0.04 versus 1.91 +/- 0.20 x 10(9)/l, P = 0.001). The occurrence of SP or PCP in patients with chronically impaired renal function was also associated with lymphopenia.. This study is the first report of delayed SP including PCP following MMF plus corticosteroids in patients with IgAN. Chronically impaired renal function might be a risk factor for severe infection, and lymphocyte counts may serve as useful and convenient tools for monitoring the intendance of the occurrence of PCP. This finding and its risk factors need to be further evaluated.

Recurrent IgA nephropathy after renal transplantation despite immunosuppressive regimens with mycophenolate mofetil.
Transplantation offers an excellent option for patients with immunoglobulin-A nephropathy (IgAN) with severe renal dysfunction. However, IgAN frequently recurs in allografts treated with azathioprine. We examined the impact of mycophenolate mofetil immunosuppression on recurrence of IgAN.. We reviewed the charts of patients transplanted for IgAN at our institution in the cyclosporin era. Patients were excluded from further analysis if follow-up was <12 months or if immunosuppression at engraftment did not include azathioprine or mycophenolate mofetil. Laboratory data, medications and allograft biopsy findings were compiled.. 152 kidney transplantations met the study criteria. At engraftment, 61 allografts were treated with azathioprine and 91 with mycophenolate mofetil. By 3 years post-transplant, IgAN developed in six of 60 (10.0%) azathioprine-treated allografts and five of 62 (8.1%) mycophenolate mofetil-treated allografts (P = 0.76). Overall, 13 azathioprine-treated and seven mycophenolate mofetil-treated allografts showed recurrence. As expected in this retrospective study, the duration of observation was longer in the azathioprine group. The interval between engraftment and diagnosis of recurrent disease was also longer. Survival of allografts with recurrent IgAN was similar in the two groups. Survival of allografts with recurrent IgAN was worse than for allografts without recurrence or allografts transplanted into patients with non-IgAN renal failure. Neither switching azathioprine to mycophenolate mofetil nor using an angiotensin-converting enzyme inhibitor or angiotensin-II type 1 receptor blocker ameliorated the clinical course after a biopsy documented recurrent IgAN.. Mycophenolate mofetil, compared with azathioprine, did not lessen the recurrence of IgAN or its clinical impact.

[Mycophenolate mofetil in high risk IgA glomerulonephritis].
Mesangial IgA glomerulonephritis (MIgAGn) is the most common biopsied primary glomerulonephritis worldwide, with a poor long-term prognosis for renal function in over a third of all patients. No proven therapy currently exists for MIgAGn. Recent studies have suggested some benefit with mycophenolate mofetil (MMF), especially in hypertensive patients with kidney failure and proteinuria, though other studies have failed to corroborate these findings. We report eight adult patients with biopsy proven MIgAGn followed in a single hospital. They all received angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers. Compassionate use of MMF was based on the presence of clinical and analytical data suggesting a high risk of short- to medium-term progression to chronic renal failure. MMF treatment was stopped after two and three months in two patients who had advanced renal failure at the start of therapy because of disease progression and greater fluid retention. Several months later they both required dialysis and kidney transplantation. The mean duration of MMF therapy in the other six patients was 15 (range: 10-18) months. The mean serum creatinine concentration fell from 1.82 +/- 0.47 to 1.55 +/- 0.41 mg/dl (p = 0.04). Protein loss in 24-hour urine collection fell from 1.95 +/- 1.35 to 0.77 +/- 0.58 g/day (p = 0.02). These results in this low number of patients showed that treatment with MMF in high-riks patients with MIgAGn and early stage kidney failure generally stabilized the disease and reduced proteinuria. MMF was well tolerated and may be of some benefit in a subgroup of patients with MIgAGn and a poor prognosis.

Therapy of IgA nephropathy with mycophenolate mofetil--report of 3 cases.
Mycophenolate mofetil is an immunosuppressive agent in transplantation which inhibits the purin neogenesis. Proliferating lymphocytes are suppressed and antibody production is decreased. Many cases of successful therapy in different kidney diseases are reported, such as diffuse proliferative lupus nephritis, pauci-immune necrotizing glomerulonephritis, focal segmental glomerular sclerosis and IgA nephropathy. We report 3 patients with IgA nephropathy who were treated with mycophenolate mofetil for more than 1 year. In all patients, proteinuria decreased significantly and the renal function remained stable. In 2 patients, kidney biopsy was repeated after 12 months and 18 months, respectively. There were no histological signs of progression of the disease. Two patients developed infections during treatment. One patient had a pneumonia, and a second patient an infection with varizella zoster. Based on our data, mycophenolate mofetil can be a potential treatment of IgA nephropathy. Further controlled studys are warranted to investigate the role of mycophenolate mofetil in IgA nephropathy.

An unusual recurrence of crescentic nephritis after renal transplantation for IgA nephropathy.
The recurrence of immunoglobulin A nephropathy (IgAN) after renal transplantation has been described in 40% to 50% of cases. For a long time, this type of recurrence was considered as a benign condition. However, recent data have shown that recurrent IgAN has become a significant cause of long-term allograft loss. The authors present here the case of a 47-year-old man with IgAN, which led to end-stage renal failure in 1999. In November 2000, he received a cadaveric renal allograft. Ten months later, acute nephritic syndrome and rapidly progressive renal failure developed. Renal biopsy showed extracapillary glomerulonephritis with crescent formation in one third of the glomeruli associated with necrosis. Steroid treatment was unsuccessful, and renal function progressively deteriorated with a creatinine level at 3.7 mg/dL 6 months after diagnosis of recurrence. This patient's graft probably will be lost in a few months.
