Cytomegalovirus infections in thoracic organ transplant recipients: Updates on prevention, treatment, and immune monitoring

Despite the success of antiviral prophylaxis and pre-emptive monitoring strategies in reducing CMV-related complications in this population, late-onset infection and antiviral resistance remain major clinical challenges. We explore the potential role of CMV in chronic rejection, evaluate the utility of CMV cell-mediated immune monitoring, and review the clinical experience with novel antivirals in TOTRs. By identifying key evidence gaps and outlining priorities for future research, this review aims to support the development of targeted and more effective CMV management strategies in this high-risk population.
