Abstract
Among various forms of glomerulonephritis, focal segmental glomerulosclerosis (FSGS) is the most common cause of end-stage renal disease leading to transplantation in children. Previous reports of the recurrence of FSGS vary widely. The North American Pediatric Renal Transplant Cooperative Study carried out a special study to determine the rate of recurrence and risk factors leading to recurrence in 132 transplants. Fifty-five percent of the patients were white children, and the remaining were black and Hispanic children. Fifty percent of the patients were under 5 yr of age at the time of the diagnosis of FSGS. Twenty-seven (20.5%) of 132 patients (95% confidence interval, 14 to 27) had a biopsy-proven recurrence of FSGS. The median time to recurrence was 14 days. The recurrence rate was similar in white children (23%) when compared with that in Hispanic children (20%) but was lower than that in black children (9%) (3 of 32 children).2+ (20%). The mean serum albumin level of patients with recurrence was 1.7 versus 2.0 g/dL for those without recurrence. The mean serum cholesterol level of patients with recurrence was 525 versus 476 mg/dL for those without recurrence. The duration of dialysis was similar in the two groups. The mean time from diagnosis to end-stage renal disease status was 33 months for patients with recurrence and 52 months for those without recurrence (P less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)
