What is the most common cause of nephrotic syndrome in children?

• A. Minimal Change Disease
• B. Focal segmental glomerulosclerosis
• C. Membranous nephropathy
• D. Diabetic nephropathy

Answer: (A)

Nephrotic syndrome in children is most commonly caused by minimal change disease. This condition typically presents with sudden edema, hypoalbuminemia, heavy proteinuria, and often normal blood pressure. It is usually idiopathic, and steroids lead to a rapid and dramatic improvement in most kids, which is a hallmark of this illness. Biopsy findings are striking in that light microscopy is largely normal, while electron microscopy shows diffuse effacement of podocyte foot processes, explaining the loss of selective albumin permeability in the glomerulus. While other causes can produce nephrotic syndrome, they are less common in children. Focal segmental glomerulosclerosis can occur and may have a more resistant course to steroids and show scarring on biopsy. Membranous nephropathy is more typical in adults and involves immune complex deposition with thickened basement membranes. Diabetic nephropathy arises from long-standing diabetes and is not a common cause in pediatric patients.
