Abstract

Background: John Cunningham virus (JCV) is one of the important viruses in immunocompromised patients. High JC viruria is seen in kidney allograft recipients; some of them with a polyomavirus associated nephropathy (PVAN) just like BK polyomavirus but to a lesser extent.
Objective :To detect JCV viruria in a sample of Iraqi renal transplant recipients, and its association with renal function.
Methods: A prospective study enrolled 71 renal transplant recipients (RTR) and 20 normal donors (ND) as controls. Urine samples were collected from all RTR and ND. Viral DNA was extracted from 1 ml urine samples, and then, JC virus DNA was detected and measured by Taqman quantitative real-time PCR.
Results: Out of 71 RTRs, 31 (43.66%), and 2 out of the 20 (10%) controls had positive JC viruria. The mean JCV viruria was 6.8 x104, and 1.04x103 copies/ml for RTRs and controls respectively.
Conclusion: There is a relatively high prevalence of JCV viruria in Iraqi RTR patients.
Keywords: JC virus, renal transplantation, urine, real-time PCR.
