title: Immunoglobulin A nephropathy in a renal allograft of a black transplant recipient.
abstract: Although IgA nephropathy (IgA N) is reportedly the most common form of primary glomerulonephritis worldwide, there is a very low incidence of IgA N in Black Americans, and IgA N in Black patients with renal allografts has not been reported. In this report, we present the case of a Black patient with endstage renal disease presumed secondary to hypertensive nephrosclerosis who developed nephrotic range proteinuria due to IgA N in a cadaveric renal allograft 2 years following transplantation. Biopsy of the allograft in the immediate post-transplantation period had revealed no evidence of IgA N. Chronic active hepatitis related to hepatitis C preceded the development of proteinuria by approximately 1 year, raising the possibility that IgA N in the renal allograft was secondary to the liver disease. The clinical and histological features of primary IgA N and IgA N secondary to liver diseases are discussed.
