An Overview of Disease and Health Research Vol. 12

Kidney transplantation is the most effective treatment for patients with end-stage kidney disease. However, post-transplant viral infections remain a major cause of morbidity and mortality due to immunosuppression required to prevent graft rejection. The risk of infection is influenced by the type of virus, intensity of immunosuppression, and host factors.  The frequently identified viruses as agents that may cause infection in case of recipients of kidney transplantation throughout the world are varicella-zoster virus, herpes simplex virus, cytomegalovirus (CMV), adenovirus, Epstein-Barr virus, BK polyoma virus (BKV) and hepatitis B. The distribution of these viruses is widespread worldwide. These microorganisms can reactivate, as these are DNA viruses, when immunosuppressive medications are given to afflicted patients. Particularly during the first six months following transplantation, these DNA viruses can result in systemic illnesses or allograft malfunction. Pretransplant evaluation, immunisation, adequate prophylaxis, and preventive measures following transplant can be adopted as effective means of reducing the frequency of these viral infections. Early detection through pretransplant screening, vaccination, prophylaxis, and post-transplant monitoring is essential to reduce complications. The primary objective of the review is to discuss viral infections that commonly occur in kidney transplant recipients, with particular focus on their origin (pathogenesis), diagnosis, prevention (prophylaxis), and management. The study reveals that CMV and BKV remain significant barriers to long-term graft survival and are associated with an increased risk of graft rejection and post-transplant malignancy. Future research should focus on improving viral surveillance strategies, developing safer immunosuppressive regimens, and exploring novel antiviral therapies and vaccines to reduce infection-related complications in transplant recipients.
