OBJECTIVES About 7% to 70% of hemorrhagic cystitis is classified as early and late-onset incidence in hematopoietic stem cell transplant patients. The association between the prevalence of viral infections and hemorrhagic cystitis was evaluated in pretransplant and posttransplant recipients and donors. MATERIALS AND METHODS Ethylenediaminetetra-acetic acid-treated blood and urine samples of 3...

The BK Virus (BKV) genome is a double-stranded, circular DNA molecule with genetic organization similar to other polyomaviruses, and high homology to JC Virus (JCV) and SV40. The archetypal form of BKV noncoding regulatory region (NCRR) is the infectious form of BKV that replicates in the urothelium and is excreted in the urine. Rearranged forms of the NCRR are found in kidney and other tissues...

Background: BK virus (BKV) opportunistic viral infection causes nephropathy and allograft loss in renal transplant recipients (RTRs).Aims: Investigating BKV seropositivity, viremia rate function were the primary goals of this study, addition to molecular study Iraqi strains (LT antigen gene).Settings Design: Case-control study.material methods: Serum plasma specimens collected from 106 RTR 100 ...

In renal transplantation, BK-virus (BKV)-associated nephropathy has emerged as a major complication, with a prevalence of 1-10% and graft loss in >50% of cases. BKV is a member of the polyomavirus family and rarely induces apparent clinical disease in the general population. However, replication of polyomaviruses, associated with significant organ disease, is observed in patients with acquired ...
