  • Title: IgA nephritis in HIV-positive patients: a new HIV-associated nephropathy?
    Author: Katz A, Bargman JM, Miller DC, Guo JW, Ghali VS, Schoeneman MJ.
    Journal: Clin Nephrol; 1992 Aug; 38(2):61-8. PubMed ID: 1516281.
    Abstract:
    Four HIV-positive patients were shown to have IgA-associated nephritis on biopsy, including one with anaphylactoid purpura. Three were homosexuals, while the fourth acquired the infection from his mother. All had hematuria, a variable degree of proteinuria and renal disease with a benign course. Serologic studies showed elevated levels of IgA as well as IgA immune complexes and rheumatoid factor. IgA antibodies to multiple HIV antigens were detected by Western blot. Pathologic studies showed tubuloreticular inclusions in endothelial cells and nuclear bodies in interstitial cells in all cases. HIV antigens were not detected in kidney biopsies by monoclonal antibodies nor was HIV viral genome demonstrated by in situ hybridization. The possibility that this represents a unique type of IgA-associated HIV nephropathy is discussed.
