The BK virus is a ubiquitous member of the group of human polyoma viruses that commonly is reactivated in the setting of immunosuppression related to renal transplantation, which results in tubulointerstitial nephritis and allograft dysfunction. BK virus-associated nephropathy occurring in association with human immunodeficiency virus infection and acquired immunodeficiency syndrome (AIDS) was reported only rarely. We describe the case of a 43-year-old man with AIDS presenting with nonoliguric renal failure. The renal biopsy specimen showed tubulointerstitial nephritis and renal tubular cell changes consistent with BK viral inclusions. Results of in situ hybridization for BK viral DNA were positive and showed tubular cell intranuclear inclusions. To our knowledge, this represents the third case of AIDS-associated BK virus-associated nephropathy diagnosed by means of biopsy.
