Congenital nephrotic syndrome

Congenital nephrotic syndrome (CNS) is a rare and uniformly fatal disease if it is not treated. Although renal transplantation has been a successful treatment, there remains a high mortality rate during the first year of life before transplantation. From 1979 to 1987, four patients with CNS, all of whom died before they could undergo renal transplantation were treated. On the basis of this clinical experience, early elective bilateral nephrectomy and dialysis for infants with CNS were initiated to improve overall outcome. From 1987 to 1989, this protocol has been used on four consecutive patients with CNS. In these patients, bilateral nephrectomy was performed only after patients suffered a serious CNS-related complication that occurred between 4 and 6 months of age. Despite nephrectomy and the need for chronic dialysis, all patients grew at normal or accelerated rates. By 16 months of age, all patients underwent successful renal transplantation.
