Of 155 children with the acquired immunodeficiency syndrome (AIDS) whom we evaluated during a 6 1/2-year period, 12 were found to have proteinuria. Histologic studies of tissue from these 12 patients revealed a wide spectrum of renal disease: focal glomerulosclerosis in 5, mesangial hyperplasia in 5, segmental necrotizing glomerulonephritis in 1, and(More)
The health-related quality of life (HRQOL) of adolescents with end-stage renal disease (ESRD) is an important marker of disease burden. Our aims were to investigate HRQOL in a group of children and adolescents with ESRD and to compare them with the reference population norms. Ours was a cross-sectional study of 81 patients aged 10 years to 21 years with(More)
The purpose of the study was to determine whether DNA polymorphisms at the renin-angiotensin-aldosterone (RAS) genes were associated with evolution to renal scar formation and, consequently, with reflux nephropathy (RN) in patients with vesicoureteral reflux (VUR). Some authors have suggested that the DD genotype of the angiotensin-converting enzyme (ACE)(More)
Kidney disease has not been considered a frequent complication in Down syndrome (DS) patients; a variety of urological abnormalities and glomerulopathies have been reported in this population, and some DS patients develop chronic renal failure (CRF).The aim of this study was to improve the understanding of renal disease in patients with DS, focusing on the(More)
AIM To establish the variables that correlate with uptake defects in dimercaptosuccinic acid (DMSA) scintigraphy performed in the acute phase of a first episode of urinary tract infection (UTI). METHODS A prospective observational study was conducted in a cohort of 158 consecutive children with a first episode of symptomatic UTI. The therapeutic delay(More)
The optimal treatment, surgical or conservative, for multicystic dysplastic kidney (MDK) is still undetermined. We analyzed prospectively the evolution of 12 children with MDK who were managed conservatively. After a mean follow-up of 32 months, the only complication found was an episode of urinary tract infection in 3 patients. Complete involution of MDK(More)
INTRODUCTION It has been generally admitted that kidneys are not affected in Cystic fibrosis (CF) patients. Anyway, there are several studies demonstrating a higher prevalence of calcium oxalate nephrolithiasis prevalence in CF patients compared to normal population. The aim of our study was to evaluate renal disease regional prevalence in CF patients (More)
INTRODUCTION Parameters allowing regular evaluation of renal function in a paediatric intensive care unit (PICU) are not optimal. The aim of the present study was to analyse the utility of serum cystatin C and beta2-microglobulin (B2M) in detecting decreased glomerular filtration rate in critically ill children. METHODS This was a prospective,(More)
The purpose of this study was to investigate the relationship between salt taste perception and blood pressure (BP) in normotensive adolescents as modified by maternal fluid losses during the first trimester of gestation. Seventy-two healthy adolescents (42 boys) aged between 9.0–21.1 years, recruited from the population-based RICARDIN study, were included.(More)
Distal renal tubular acidosis (RTA) with nerve deafness is caused by mutations in the ATP6V1B1 gene causing defective function of the H+-ATPase proton pump. We report five acidotic children (four males) from four unrelated families: blood pH 7.21–7.33, serum bicarbonate 10.8–14.7 mEq/l, minimum urinary pH 6.5–7.1 and fractional excretion of bicarbonate in(More)
