[HIV-associated nephropathy with amoebic enteritis: a case report and literature review].

We herein describe a case of HIV-associated nephropathy (HIVAN) in a 64-year-old HIV antibody-positive man presenting with proteinuria. Laboratory examinations showed positive proteinuria, a high β2-microglobulin level and decreased creatinine clearance. He underwent a percutaneous renal biopsy, and a pathologic evaluation revealed a collapsing form of focal sclerosing glomerulosclerosis. Histologically, HIVAN is a collapsing form of focal sclerosing glomerulosclerosis (FSGS), which can be distinguished from idiopathic FSGS by the presence of microcystic tubular dilatation and interstitial inflammation. The patient was diagnosed with HIV-associated nephropathy and was started on ART. The HIV-associated nephropathy did not progress to acute renal failure, and long-term survival has been observed for over 12 years.
