Case report : a toddler with anasarca caused by congenital nephrotic syndrome

Abstract

Congenital nephrotic syndrome is a rare inherited disorder arising from defects in the proteins of the cells in the glomerular basement membrane and develops either in utero or at birth. The clinical presentation is the result of massive protein loss in the urine with associated compensatory mechanisms. Here we present a clinical case of a female toddler with a history of anasarca (severe generalised edema) from birth and who presents with the classical biochemical laboratory findings of nephrotic syndrome, together with the more pronounced features that arise from protein loss including abnormal thyroid function testing and a marked hypercholesterolaemia. Renal biopsy indicated congenital nephrotic syndrome of the Finnish type. This clinical-diagnostic case report represents an example of the broad spectrum of pathophysiological findings of a severe congenital nephrotic syndrome.
