Abstract
John Cunningham (JC) virus is a well-known cause of progressive multifocal encephalopathy. Only a few cases of polyomavirus-associated nephropathy due to JC virus have been reported so far. We report one such case in a kidney transplant recipient who presented with proteinuria and increased serum creatinine. Allograft biopsy revealed polyoma virus-associated nephropathy. Real-time polymerase chain reaction revealed negative result for BK and JC virus in the blood, negative for BK virus and positive for JC virus in the urine, and fi nally, when performed on the biopsy sample it detected more than 106 copies of JC virus DNA, which allowed us to establish JC virus-associated nephropathy as a defi nitive diagnosis. The patient was treated with intravenous immunoglobulins and reduction of immunosuppression. Serum creatinine returned to initial levels with decrease of proteinuria. This case documents that JC virus may cause signifi cant changes in renal allograft and should be included in the differential diagnosis of allograft dysfunction.
