IgA nephritis in a child with human immunodeficiency virus: a unique form of human immunodeficiency virus-associated nephropathy?
A 9-year-old boy is presented who was antibody positive for human immunodeficiency virus (HIV) and who had recurrent episodes of gross hematuria. Renal biopsy revealed findings typical of IgA nephropathy but also showed electron-microscopic abnormalities seen with HIV-associated nephropathy. In addition, IgA antibodies to multiple HIV proteins were detected in serum by Western blot analysis, and circulating immune complexes of the IgA class were present. Although HIV-associated nephropathy and IgA nephropathy are thought to be distinct conditions, five adults with a similar combination of findings have been reported, and our patient adds to the evidence for a link between these two entities in some patients. We propose that the histological parallels between the conditions may merely represent the limited renal responses available to multiple types of injuries, and we support the attempts underway to probe renal tissue for the HIV genome.
