Abstract:
We report a case of acute tubulointerstitial nephritis with giant cell tubulitis and tubular basement membrane immune complex deposits in a patient with membranous lupus nephritis. The patient, who had no prior evidence of lupus nephritis, developed acute kidney failure and mild proteinuria after cardiac valve replacement surgery. Giant cell tubulitis with tubular basement membrane immune complex deposits has been described in 4 patients after cardiac surgery, 3 of whom received cefuroxime, suggesting the possibility of a drug hypersensitivity reaction. The present case suggests there may also be a pathogenetic role for autoimmunity in this condition.

The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous capillaries...
