What is the true significance of donor-related cytomegalovirus transmission in the setting of facial composite tissue allotransplantation?

ABSTRACT

Face transplantation (FT) is fraught with complications parallel to solid organ transplantation (SOT). As such, donor-related cytomegalovirus (CMV) transmission remains one of the most commonly feared viruses associated with FT. With this in mind, a review of the literature seemed justified, knowing that two of the first four face transplant recipients acquired CMV donor-related viral infection. Although the risk of CMV transmission is acceptable in the setting of SOT, the scenario for those composite tissue allotransplantation (CTA) patients, who are often young and healthy, may be different. Experiences from France and Cleveland have both confirmed suboptimal events related to CMV transmission following transplantation. Therefore, using the information provided here, it is imperative that all FT teams remain aware of these potential risks. Furthermore, all patients pursuing facial CTA should be fully informed as to the risks of donor-related CMV transmission, understand the importance of prophylaxis, and be aware of alternative therapies required to prevent symptomatic disease.
