BK virus reactivation and disease is emerging as an important cause of allograft dysfunction and loos, and the incidence of BKV reactivation and disease appears to be rising. This has been attributed to the recent us of newer, highly potent immunosuppressive agents. Little is known about the biologic behavior of the virus after reactivation and it progression to disease in heart transplant recipients. We aim to describe the prevalence of BK reactivation in urine and plasma samples of 100 pilot patients to begin to elucidate these gaps in our knowledge that may impact morbidity and mortality following heart transplantation.
- Heart transplant patients aged 18 years or older who receive their post-transplant care exclusively at Tufts Medical Center.
- Dialysis dependence
- Combined heart-kidney transplantation
- Physical or cognitive impairment which would prevent provision of informed consent.
