Recurrent postinfectious glomerulonephritis: an unusual evolution compatible with C3 glomerulopathy.

Acute endocapillary glomerulonephritis, as its name suggests, is a one-time process, which usually resolves within weeks. However, in a small percentage of patients, the disease becomes chronic. In these cases, a deregulation in the alternative complement pathway, which can be caused by mutations or autoantibodies, has been proposed as a pathophysiological mechanism. As a result, the alternative complement pathway remains active after resolution of infection. We report a patient with two episodes of acute renal failure, both times diagnosed by renal biopsy of acute endocapillary glomerulonephritis, with slow recovery after two episodes of low-serum complement C3, haematuria and proteinuria.
