What is the rationale for administering ganciclovir post-organ transplantation?

Administering ganciclovir post-organ transplantation focuses primarily on its antiviral properties, specifically its effectiveness in preventing cytomegalovirus (CMV) infection. After a transplant, patients are at a heightened risk for CMV due to the immunosuppressive medications required to prevent organ rejection. These immunosuppressants can decrease the immune system’s ability to combat infections, including those caused by CMV, which is a common opportunistic pathogen in transplant recipients.

Ganciclovir works by inhibiting the replication of the virus, thus reducing the risk of developing CMV disease. This preventative approach is crucial because CMV can lead to significant complications, such as graft dysfunction, prolonged hospitalization, and even increased mortality in transplant patients. Therefore, the administration of ganciclovir is a proactive measure in the management of transplant recipients to maintain their health and the successful function of the new organ.
