tacrolimus and Hematuria

Given that more cancers are being diagnosed earlier and that treatment of cancer is improving, health issues of cancer survivors are becoming more common and apparent. Pelvic radiation therapy for the treatment of gynecological cancers can lead to long-term collateral damage to the bladder, a condition termed radiation cystitis (RC). Late sequelae may take many years to develop and include incontinence and pain as well as hematuria. RC is a rare but potentially life-threatening condition for which there are few management and treatment options.. There are limited data in the literature regarding the effects of radiation on the bladder after gynecological cancer therapy and we hereby review the literature on cancer survivorship issues of pelvic radiation for gynecology literature.. Treatment options are available for patients with radiation-induced hemorrhagic cystitis. However, most treatments are risky or only effective for a short timeframe and no therapy is currently available to reverse the disease progress. Furthermore, no standardized guidelines exist describing preferred management options. Common therapies include hyperbaric oxygen therapy, clot evacuation, fulguration, intravesical instillation of astringent agents, and surgery. Novel developing strategies include Botulinum Toxin injections and liposomal-tacrolimus instillations. These treatments and strategies are discussed.. In this review, we will present current and advanced therapeutic strategies for RC to help cancer survivors deal with long-term bladder health issues.

Children with severe Henoch-Schönlein purpura nephritis (HSPN) may progress to end-stage renal disease without appropriate treatment.. This study aimed to investigate the efficacy and safety of tacrolimus combined with glucocorticoids in the treatment of pediatric HSPN.. A total of 87 HSPN patients with urinary protein ≥ 0.75 g/24 h received standard of care, including angiotensin II receptor blockers/angiotensin-converting enzyme inhibitors and glucocorticoids. Patients were divided into three groups and additionally received tacrolimus (n = 30), cyclophosphamide (n = 31), or mycophenolate mofetil (MMF) (n = 26). We monitored outcome measures, including proteinuria, hematuria, and renal function and analyzed the efficacy and side effects in each group.. At 2-month follow-up, the overall efficacy was 93.3%, 83.9%, and 61.5% for tacrolimus, cyclophosphamide, and MMF, respectively (P < 0.05). Urinary protein significantly decreased for all groups. Urinary red blood cell counts significantly decreased for patients treated with tacrolimus (P < 0.001) and cyclophosphamide (P < 0.05), whereas no significant decrease was seen for those receiving MMF (P = 0.09). Although urine β2-microglobulin significantly decreased following 2 months of treatment with all medications, efficacy was greater with tacrolimus than with cyclophosphamide and MMF (P < 0.001). Major adverse events were respiratory and urinary infections, with MMF having the highest infection rate. The cyclophosphamide group also experienced additional adverse events, including arrhythmia, hemorrhagic cystitis, leukocytosis, thrombocytopenia, and hyperglycemia.. These results indicate that tacrolimus is more effective at reducing proteinuria and hematuria and improving renal function, with relatively milder side effects, in the treatment of pediatric HSPN..

FK506 is an immunosuppressive drug and a calcineurin inhibitor that has been widely used in kidney disease in recent years. FK506 shows a wide range of biological and pharmaceutical effects; however, the mechanism of its anti- proliferative effect has not been well elucidated. An IgA nephropathy (IgAN) model was used to generate a mesangial cell proliferation model. This study aims to examine the effect of FK506 on IgAN rats and the underlying mechanisms.. Hematuria, proteinuria and renal function were measured. To observe the pathological conditions, we performed HE (hematoxylin - eosin) and PAS (periodic acid - schiff) staining. Transcription and protein expression levels were detected by qRT - PCR (quantitative real-time polymerase chain reaction) and Wb (western blotting). The location and semi-quantitative expression levels of TRPCs, CaN (Calcineurin) and α-SMA were examined by IHC (Immunohistochemical staining).. We found that FK506 could improve hematuria, proteinuria and renal function, especially in the HF (high-dose FK506) groups. Renal pathological changes were ameliorated in the treatment groups. FK506 could significantly decrease TRPCs, CaN, phosphorylation of ERK1/2 and α-SMA expression.. Taken together, these results suggest that the therapeutic effect of FK506 on IgAN might be partially associated with the down-regulated expression of TRPC channels, CaN and phosphorylation of ERK1/2.

Kimura's disease (KD) with renal involvement is a rare disease. Optimal treatments are still not well established. It is necessary to analyze clinicopathological features, treatment responses, and prognosis for improving KD diagnosis and treatment.. Clinicopathological data, treatment responses, and prognosis were collected and analyzed retrospectively.. The patients consisted of 27 males and 2 females, with an average age of 35.5 ± 15.1 (13 - 61) years. 27 exhibited proteinuria ranging from 0.730 to 14.1 g/24 h (5.98 ± 3.40 g/24 h). Hypertension, renal insufficiency (serum creatinine (Scr) > 1.24 mg/dL), and microhematuria occurred in 4 (13.8%), 11 (37.9%), and 13 (44.8%) cases, respectively. Light microscopy (LM) identified mesangium proliferation, minimal change, focal and segmental glomerulosclerosis (FSGS), membranous glomerulonephritis, membranoproliferative glomerulonephritis (MPGN), and acute tubular necrosis in 14, 8, 3, 2, 1, and 1 cases, respectively. All were treated with Tripterygium wilfordii (TW), prednisone, leflunomide (LEF), tacrolimus (FK506), myophenolate mofetil (MMF), or renin-angiotensin system blockers (RASI). 26 patients were followed up for 1.60 - 108.7 months (39.6 ± 28.7). After treatments, urinary red blood cells (RBC) decreased in all. The amount of 24-hour urinary protein (24-hUPE) decreased in 24 patients. 22 reached complete remission (CR), 4 partial remissions (PR). The patients who did not relapse were younger than those who relapsed.. KD with renal involvement occurs predominantly among 35 - 50 year old Chinese patients with male predilection. The most common features are proteinuria, hypertension, micro hematuria with minimal change, and mesangial proliferative glomerulonephritis. Most were responsive to treatment, but could relapse. Gender, age, and hypertension are associated with KD recurrence. The prognosis is good mostly.

Hemorrhagic cystitis is a rare and severe late complication of pelvic radiation, and there is no regulatory-approved drug treatment. We present an 81-year-old man with a history of localized prostate cancer, which was treated with external beam radiation therapy and subsequently developed severe hemorrhagic radiation cystitis for which he has failed several treatments. We present the novel use of intravesical tacrolimus for the treatment of refractory radiation cystitis and gross hematuria. The patient tolerated the treatment well, and it resulted in the resolution of his gross hematuria without further consideration for formalin instillation or cystectomy and diversion. Intravesical tacrolimus is a safe, minimally invasive, and promising treatment option for radiation hemorrhagic cystitis.

A 53-year-old man who underwent successful kidney transplantation for stage 5 chronic kidney disease presented to our clinic with intermittent painless gross hematuria. Urachal adenocarcinoma, stage III A by Sheldon system, was diagnosed after serial histopathologic and radiological studies. The patient was treated with extended partial cystectomy, en bloc resection of urachus and umbilicus, pelvic lymphadenectomy, and ileocystoplasty. There were no complications seen in this patient. Neither urachal adenocarcinoma recurrence, metastasis, nor de novo uroileal cancer developed during 48-month follow-up. His reconstructed bladder functioned efficiently, without compromising the transplanted kidney function. Our case demonstrated that conservative surgery and augmentation ileocystoplasty could be offered to kidney transplant recipients with localized urachal carcinoma.

HC and HU predispose healthy children to develop hematuria and nephrolithiasis. The natural history of HC and HU has not been studied in renal transplant recipients who may be at greater risk of complications. Our study investigated the prevalence of HC and HU after Tx and determined independent predictors of urinary calcium and uric acid excretion. Twenty-five pediatric transplant patients were studied between one and 12 months after Tx. Demographic data and measurements of the random Uca/cr and uric acid excretion were collected. Multivariable regression analyses were used. The median age of the patients was 10.6 yr. The prevalence of HC and HU was 20% each at one month. At 12 months, 20% had HC and 13% had HU. There were no predictors for HC; for HU, the only predictor was systolic hypertension (p = 0.03). Our data demonstrate a high prevalence of HU and HC in pediatric renal Tx recipients. The long-term clinical implication of these metabolic abnormalities remains to be elucidated in prospective trials.
