ABSTRACT

Henoch-Schonlein purpura (HSP) is the most common childhood vasculitis. Renal involvement in HSP is one of the major causes of chronic renal failure in children. It is important to start effective and relatively safe medication to prevent end-stage renal disease (ESRD). Mycophenolate mofetil (MMF) appears to be a promising therapeutic agent in many autoimmune diseases such as lupus nephritis and vasculitis. Herein, we describe the treatment with MMF of three patients with HSP nephritis. In two cases with rapidly progressive glomerulonephritis without response to steroid, after treatment with MMF, significant improvement in kidney function and proteinuria were observed. In another patient with HSP nephritic-nephrotic syndrome who showed resistance to steroid, MMF offered a favorable effect. MMF seems to be a promising therapeutic agent in the treatment of the severe HSP nephritis.

ABSTRACT

OBJECTIVE: Peritoneal dialysis remains the only available option for patients which need immediate dialysis and it could be a bridge between end-stage renal failure (ESRD) and transplantation. There is a paucity of published experience of children with immediate use of permanent Tenckhoff Catheter for peritoneal dialysis from developing countries. In this study we report our experience on immediate use of permanent peritoneal access and continued peritoneal dialysis for a prolonged time. METHODS: Fifty six patients were studied including 30 males and 26 females within the age range of 1 month to 14 years with mean age of 6.5 years in Urmia, Northwest Iran. FINDINGS: No operative morbidity was seen. During a total of 499.5 continuous ambulatory peritoneal dialysis months, 16 patients had 28 episodes of peritonitis, which means a overall result of one episode per 17.8 months. There were 3 patients (5.35%) with catheter site leakage, 12 (21.4%) catheter obstructions (which led to omentectomy), 4 (7.2%) exit site infections (2 patients in the early postoperative period and 2 patients in during follow up). Death due to catheter related complications occurred in 1 per 56 patients and due to non-catheter related causes in 10 per 56 patients. CONCLUSION: Present results indicate that catheter-related complications were not higher than those previously reported and peritoneal dialysis could be initiated immediately after catheter implantation and could be a safe bridge between end-stage renal failure (ESRD) and transplantation.

ABSTRACT

PURPOSE: Our aim was to determine association of vesicoureteral reflux (VUR) and idiopathic hypercalciuria in children with recurrent and single episode of urinary tract infection (UTI). MATERIALS AND METHODS: The study group consisted of 45 children with VUR and recurrent UTI, and 2 control groups: 45 normal healthy children (control group 1) and 45 children with VUR and single episode of UTI (control group 2). Idiopathic hypercalciuria was defined as urine calcium to creatinine ratio more than 0.8 (mg/mg) in infants younger than 1 year old, and more than 0.2 (mg/mg) in older children (without any detectable causes for hypercalciuria). RESULTS: The study group consisted of 26 (57.8%) girls and 19 (42.2%) boys, with the mean age of 41.14 +/- 22.1 months. Nine (20%) subjects had hypercalciuria. The control group 1 composed of 22 (48.9%) girls and 23 (51.1%) boys, with the mean age of 43.98 +/- 16.23 months. In this group, 6 subjects (13.3%) with hypercalciuria were detected. The control group 2 composed of 23 (51.1%) girls and 22 (48.9%) boys, with the mean age of 39.96 +/- 24.2 months. In group 2, 7 subjects (15.6%) with hypercalciuria were detected. CONCLUSION: Comparison between such results was not statistically significant. Despite reports of different studies about accompanying of hypercalciuria with recurrent UTI with or without anatomical abnormalities, according to the present study, idiopathic hypercalciuria is not a major contributing factor to recurrent UTI in children with VUR.

ABSTRACT

INTRODUCTION: The aim of this study was to evaluate the accuracy of Technetium Tc 99m dimercaptosuccinic acid (99mTc-DMSA) renal scintigraphy in the diagnosis of urinary tract infection (UTI) in children with suspected infection but with a negative urine culture. MATERIALS AND METHODS: The records of all children with suspected or definite diagnosis of UTI presented during a 2-year period were reviewed in this study. Abnormal findings on renal scintigraphy, voiding cystourethrography (VCUG), and ultrasonography were evaluated and compared between the patients with the definite diagnosis of UTI and those with suspected UTI and negative urine cultures. RESULTS: Of 210 patients, 86 had a definite diagnosis of UTI (group 1) and 124 had suspected UTI without a positive culture (group 2). Abnormal findings on DMSA scans were seen in 76 patients (88.4%) in group 1 and 84 (67.7%) in group 2. Vesicoureteral reflux was detected by VCUG in 50% and 32.3% of the patients in groups 1 and 2, respectively. In group 2, vesicoureteral reflux was seen in 40.5% of the patients with abnormal DMSA scan. Ultrasonography findings were abnormal in 51.3% and 39.8% of the patients with abnormal DMSA scan findings in groups 1 and 2, respectively. CONCLUSION: According to our findings, in children with a negative urine culture and abnormal urinalysis, 99mTc-DMSA renal scintigraphy is helpful in diagnosing UTI and vesicoureteral reflux; we recommend VCUG when DMSA scan supports UTI despite a negative urine culture and a normal ultrasonography.
