Updates in the Diagnosis and Treatment of BK Viraemia in Kidney Transplant Recipients: Current and Future Insights.

BK virus is a common childhood infection that is largely asymptomatic in the general population. However, increased cellular immune dysfunction in kidney transplant recipients is associated with an increased risk of BK virus reactivation. Modern immunosuppression regimens have resulted in a reduction in transplant rejection events but increased risk of BK nephropathy. It is now considered a leading cause of allograft loss within the first year of transplantation. Despite advances in screening, it remains both a diagnostic and therapeutic challenge. This review aims to provide an up-to-date summary of the latest clinical research in the diagnosis and treatment of BK virus in kidney transplant recipients. It will also provide a concise overview of emerging diagnostic techniques and new therapies under investigation.
