DIAGNOSIS AND MANAGEMENT OF BK POLYOMAVIRUS INTERSTITIAL NEPHRITIS IN RENAL TRANSPLANT RECIPIENTS

Abstract

Interstitial nephritis due to BK polyomavirus occurred in 2.5% of patients receiving renal transplants at our center since 1996. Polyomavirus infection can cause transplant dysfunction and graft loss, but progression of the infection can frequently be abrogated with alterations in immunosuppressive therapy. Both renal biopsy and EM of urine samples are useful in the diagnosis and monitoring of polyomavirus infections.
