Cytomegalovirus in solid organ transplantation: epidemiology, prevention, and treatment

Cytomegalovirus (CMV) is one of the most important pathogens that infect solid organ transplant recipients. CMV is associated with increased morbidity and mortality in this population as a result of its numerous direct and indirect effects. Prevention strategies consist of preemptive therapy and antiviral prophylaxis, and the choice of which preventive approach to implement should be guided by advantages and drawbacks related to the population being managed. There are differences in the approaches to the laboratory diagnosis and treatment of CMV infection and disease depending on assay availability, clinical presentation, disease severity, and specific transplant populations. In this article, the authors aim to summarize recent publications and updates in the epidemiology, diagnosis, prevention, and treatment of CMV infection in solid organ transplant recipients during the past year, including a brief review of future directions in the field.
