title: Crescentic IgA nephropathy as a manifestation of human immune deficiency virus infection.
abstract: A 37-year-old Caucasian male homosexual presented with hematuria and rapidly progressive acute renal failure. He was found to have proteinuria and microscopic hematuria as well as RBC casts. Investigations revealed polyclonal gammopathy with five times normal serum IgA levels as well as elevated serum IgG. Renal biopsy showed evidence of crescentic IgA nephropathy with ultrastructural changes of tubuloreticular inclusions described in HIV nephropathy. He was found to be positive for human immunodeficiency viral antibodies. Renal function improved during follow-up after two doses of 1 g each of methylprednisone. In our opinion, this is the first case of HIV-related crescentic IgA nephropathy. HIV testing should be performed more frequently in patients presenting with acute glomerular diseases.
