Until now oligonephropathy to indicate "too few nephrons" has been associated with intrauterine growth restriction and experimentally induced abnormalities of renal development. The purpose of this study was to determine whether there is evidence of abnormal postnatal glomerulogenesis in extremely low birth weight preterm infants. Renal autopsy tissue was(More)
Focal segmental glomerulosclerosis (FSGS) is a glomerular disease characterized by proteinuria, progression to end-stage renal disease, and recurrence of proteinuria after kidney transplantation in about one-third of patients. It has been suggested that rituximab might treat recurrent FSGS through an unknown mechanism. Rituximab not only recognizes CD20 on(More)
The long-term outcome of 20 preterm infants with extremely low birth weight and acute renal failure in the neonatal period was studied retrospectively over an 18-year period. Those with progressive renal disease are compared with those with normal renal function. Current mean age is 7.5±4.6 years (range 3.2–18.5 years). Nine patients showed deterioration in(More)
OBJECTIVES To distinguish between cystatin C (CysC) and creatinine (Cr) as markers of estimated glomerular filtration rate (eGFR) in preterm infants and to correlate eGFR with total kidney volume (TKV) as a surrogate of nephron mass. STUDY DESIGN Sixty preterm (<37 weeks' gestational age [GA]) and 40 term infants were enrolled at birth. Serum Cr and CysC(More)
Posterior reversible leukoencephalopathy syndrome (PRES) clinically presents with seizures, severe headaches, and mental and visual changes. Our goal was to describe the clinical features, triggering factors, neuro-imaging findings, and electroencephalogram (EEG) findings in a pediatric cohort with renal disease. We retrospectively analyzed the records of(More)
OBJECTIVE To assess the prevalence of abnormal vitamin D status in children and adolescents with chronic kidney disease (CKD). STUDY DESIGN This was an outpatient cross-sectional, retrospective study of 258 patients, mean age 12.3 +/- 5.2 years, with an average estimated glomerular filtration rate (eGFR) of 106 +/- 51 mL/min/1.73 m2 (range, 0 to 220(More)
Recurrence of focal glomerulosclerosis (FSGS) following renal transplantation is a common cause of allograft loss and clinical morbidity. Recent attempts to control proteinuria and morbidity with plasmapheresis (PP) have met with limited success. Our experience with the use of mycophenolate mofetil (MMF) and angiotensin blockade (AB) in the management of(More)
BACKGROUND AND OBJECTIVES Childhood-onset lupus nephritis (LN) carries a worse renal prognosis compared with adults. Controlled treatment trials in children are lacking. We compared renal and patient survival in a cohort of pediatric patients followed over 3 decades. DESIGN, SETTINGS, PARTICIPANTS, & MEASUREMENTS A retrospective analysis was conducted on(More)
Preterm birth is associated with decreased nephron mass and obesity that may impact on kidney disease progression in later life. Our objectives were to examine the relative risks of obesity and preterm birth on the progression of kidney disease in children. In a retrospective cohort study, 80 (44 obese and 36 non-obese) patients with proteinuric kidney(More)
Three children under the age of 3 years presented with malignant hypertension, proteinuria, and acute kidney injury. Takayasu’s arteritis was diagnosed on the basis of clinical symptoms of weight loss and low grade fever in conjunction with elevated sedimentation rate and radiographic evidence of aortic and renal artery stenosis. One patient had a renal(More)
