We report clinical and pathological data in 56 adolescents presenting with gross hematuria (GH) and 65 presenting with idiopathic nephrotic syndrome (INS). IgA nephropathy (present in 52%) and other mesangial lesions were found in the majority of the 56 patients with GH. Many of these patients had complex urological procedures prior to consideration of a(More)
Anti-neutrophil cytoplasmic autoantibodies (ANCA) are usually determined during the diagnostic evaluation of systemic vasculitis and glomerulonephritis syndromes in adult patients, but few pediatric patients with ANCA have been reported. We describe five pediatric patients with ANCA and glomerulonephritis, with and without upper or lower respiratory tract(More)
The study sought a diagnostic clue to identify the group of pediatric patients with apparent minimal change disease who subsequently develop focal glomerular sclerosis (FGS). Review of all renal biopsy material at our institutions identified 42 pediatric patients who met the standard criteria for minimal change disease (MCD) on initial biopsies. Of those,(More)
As hypertensive target-organ damage has been associated with diminished diurnal blood pressure (BP) variation in adults, we compared diurnal BP patterns of hypertensive adolescents with left ventricular hypertrophy with normotensive and hypertensive adolescents with normal left ventricular mass. In addition, the frequency of microalbuminuria (Malb),(More)
In one sibship, a brother had membranoproliferative glomerulonephritis (MPGN) Type III and a sister, Type I. In both children, clinical and laboratory manifestations were typical. In another sibship, both boys had Type I MPGN by glomerular morphology but over a 4 year period of follow-up, neither had hematuria or hypocomplementemia, both common(More)
Children with minimal lesion nephrotic syndrome (MLNS) may later develop focal segmental glomerulosclerosis (FSGS). It has been suggested that a low percentage of epithelial podocyte effacement (EPE) and a high degree of epithelial cell vacuolization (ECV) in nonsclerotic glomeruli presage FSGS, and that extensive epithelial cell vacuolization in biopsies(More)
Clinical histories and renal biopsies were reviewed in 12 children with acute tubulointerstitial nephritis, which was drug related in eight, idiopathic in one, and multifactorial in three. Presentation with rashes and hypertension was most common in patients with drug-associated nephritis. Eosinophils, which were present in the majority of the renal(More)
Autosomal recessive Alport syndrome can arise from a mutation in either of the genes COL4A3 and COL4A4 on chromosome 2, which encode, respectively, the alpha 3 and alpha 4 chains of Type IV collagen. This report describes a mutation in COL4A3 in a girl who presented at age 5 with hematuria and proteinuria, lacking any family history of renal disease. Renal(More)
The steady-state pharmacokinetics, renal function and quantitative beta 2-microglobulin (beta 2-M) excretion were prospectively evaluated in 22 very low birth weight (VLBW) infants (700-1,470 g birth weight and 25-33 weeks gestational age) receiving 2.4 mg/kg gentamicin at randomly assigned 12- or 18-hour dosing intervals. Gentamicin trough concentrations(More)
Bone mineral density (BMD) is decreased in both adult and pediatric renal transplant recipients. To investigate the risk factors associated with this decrease in BMD post-renal transplant, we studied 33 children, aged 7-22 yr, who had received a renal transplant from 0.3 to 10 yr prior to this study. BMD analysis of the total body, spine, and femur was(More)
