Primary Membranoproliferative Glomerulonephritis

What is Primary Membranoproliferative Glomerulonephritis?

Membranoproliferative glomerulonephritis (MPGN) is a chronic progressive kidney disorder characterized by glomerular capillary wall structural changes and mesangial cell proliferation leading to nephrotic syndrome, hypocomplementemia, hypertension, proteinuria and end-stage kidney disease. MPGN can be due to either idiopathic (type 1, 2 and 3 MPGN; see these terms) or secondary (associated with infectious and immune complex diseases) causes. The primary form affects children and young adults between 8 and 30 years old. The secondary form affects adults over 30 years old.(1,2)
