Kidney disease is a common manifestation in HIV-infected patients. The spectrum of disease in HIV-infected patients varies, from HIV-associated nephropathy (HIVAN), which is manifest by collapsing glomerulopathy, to usual FSGS, minimal change disease, thrombotic microangiopathy, and lupus-like HIV-immune complex kidney disease (HIVICK). Other immune complex diseases may also occur in HIV-infected patients, including IgA nephropathy and postinfectious glomerulonephritis, and are best diagnosed as those specific entities.
