title: Distinguished Scientists Lecture Series. HIV-associated nephropathy.
abstract: HIV-associated nephropathy is manifested by heavy proteinuria and renal insufficiency and characterized pathologically by the collapsing variant of focal and segmental glomerulosclerosis with acute tubular necrosis and mild interstitial inflammation. Untreated, it may result in end-stage renal disease in as little as 4 months. It may present in patients with any manifestation of HIV infection, and affects predominantly black individuals. Insights into pathogenesis have come from a transgenic mouse model, renal cell cultures, and from study of human biopsy material. Although the pathogenesis is not completely understood, current considerations revolve around the role of HIV or protein in renal epithelium and the effects of cytokines, including transforming growth factor-beta and basic fibroblast growth factor, on renal structures. Therapy with zidovudine, corticosteroids, or angiotensin-converting enzyme inhibitors has met with modest success; to date, protease inhibitors have not been assessed.
