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.

The effect of omega-3 fatty acids on the atherogenic lipoprotein phenotype in patients with nephrotic range proteinuria.
Patients with nephrotic range proteinuria are known to have an increased risk of cardiovascular disease partly due to possessing the atherogenic lipoprotein phenotype. The aim of this study was to examine the effect of high dose omega-3 fatty acids on atherogenic triglyceride rich lipoproteins in patients with nephrotic range proteinuria, comparing their effect on lipoprotein profiles in age and sex matched controls.. 17 patients with nephrotic range proteinuria and 17 age and sex matched controls were studied. Fasting lipids and lipoproteins were measured before and after 8 weeks treatment with 4 g daily of omega-3 fatty acids (Omacor®).. In patients with proteinuria treatment reduced plasma triglyceride by a mean of 0.45 mmol/l (95%CI 0.16 - 0.74, p = 0.005) and plasma very low density lipoprotein cholesterol by a mean of 0.38 (95%CI 0.01 - 0.75, p = 0.04). LDL III concentration fell from 178.8 mg/dl (61.6 - 231.0) to 96.1 mg/dl (49.3 - 204.5), p = 0.05. In patients treatment altered the LDL profile so that LDLIII which was the major subfraction present at baseline was reduced from 49.9% to 29.8% (p = 0.01). Remnant lipoproteins (RLP) also fell with a mean reduction of 3.5 mg/dl in RLP-Cholesterol (95%CI 0.1 - 6.9, p = 0.05) and 12.4 mg/dl in RLP-triglyceride (95%CI 2.6 - 22.2, p = 0.03). There was however a 0.6 mmol/l rise in LDL-C (p = 0.06) in the patients. Treatment did not alter HDL-C.. In patients with nephrotic range proteinuria, omega-3 fatty acids reduced triglyceride rich lipoproteins, LDL III and remnant lipoproteins. A tendency to an increase in LDL-C was observed but this was offset by an alteration in the distribution of the LDL profile towards lighter, larger LDL particles. We propose that treatment with omega-3 fatty acids in conjunction with a statin may be the ideal therapy in these patients.

Is body size a biomarker for optimizing dosing of omega-3 polyunsaturated fatty acids in the treatment of patients with IgA nephropathy?
Re-analysis of the North American IgA Nephropathy Study suggested that efficacy of omega-3 polyunsaturated fatty acids (omega-3 PUFA) was dosage-dependent on the basis of body size and plasma omega-3/omega-6 and eicosapentaenoic acid (EPA)/arachidonic acid (AA) ratios. The objective of this study was to confirm these assertions. Data from a previously reported randomized 2-yr clinical trial in which two dosages of an ethyl ester omega-3 PUFA (Omacor) were given to 73 high-risk patients with IgA nephropathy were reviewed. Omacor also was used in the North American IgA Nephropathy Study. Parameters included body weight; body mass index (BMI); plasma phospholipid AA, EPA, and docosahexanoic acid (DHA) levels and serum creatinine and 24-h urine protein (UP) levels during the 2-yr trial; and time to ESRD after 6.4 yr. Plasma phospholipid levels of EPA, DHA, and EPA/AA ratios were significantly inversely correlated with increasing body weight and BMI in the Omacor 4-g dosage group but not in the Omacor 8-g dosage group. Conversely, increasing levels of lipid parameters were observed with increasing dosages of Omacor (EPA+DHA) in grams per kilogram of body weight at 6 wk of treatment. None of the plasma omega-3 PUFA levels, EPA/AA ratios, or Omacor dosage per kilogram was significantly associated with reciprocal serum creatinine or UP slopes during the 2-yr trial or with ESRD. This post hoc analysis of body weight and BMI, plasma omega-3 PUFA status, and renal outcome did not find that treatment efficacy of omega-3 PUFA was dosage dependent on the basis of body size.

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.
