Diagnosis and treatment of HIV-associated nephropathy.

Human immunodeficiency virus-associated nephropathy (HIVAN) is a distinct clinico-pathological syndrome that occurs almost exclusively in black patients with an AIDS defining diagnosis. It is characterized by rapidly progressive renal failure with a severe nephrotic syndrome. The renal biopsy typically shows a collapsing glomerular sclerosis and variable tubulo-interstitial nephritis. The pathogenesis most likely involves infection of renal tubular and epithelial cells with HIV. The use of ACE-inhibitors and steroids may slow down the progression to end-stage renal failure. With the introduction of highly active anti-retroviral therapy, HIVAN may now be treated effectively although clinical data are so far limited to case-reports.
