Background: Cytomegalovirus (CMV) infection usually occurs asymptomatically but can represent an important cause of morbidity and mortality in patients with compromised immune system such as transplant patients. Infection may not respond to standard therapies leading to refractoriness (with or without resistance) which jeopardizes transplant successful outcome.
Objective: Since refractoriness represents a critical point, a project has been conducted to verify the epidemiology in the Italian context and to convey the current patients’ unmet medical needs.
Methods: The project included: literature analysis, expert interviews and results’ validation through expert opinion. Based on literature data, a questionnaire was built and submitted to 8 experts with proven experience in the management of post-transplant CMV infection. Topics included epidemiology, patient management, unmet needs and future perspective. Outcomes were validated by 3 additional national experts in solid organ transplantation, hematopoietic stem cell transplantation and infectious diseases.
Results: Epidemiological rates from literature applied to current transplantation numbers in Italy estimate approximately 109 adults and 8 children with refractory post-transplant CMV infection in 2021.
If valganciclovir/ganciclovir are ineffective, foscarnet is predominantly used. When foscarnet fails, patients have no therapeutic alternatives. Despite being a minority, this represents a high medical need. Therefore, the introduction of new therapeutic options with a better efficacy/safety profile would lead to a significant improvement in refractory CMV infection management.
Conclusion: Although refractory infections represent a minority, they are the most critical issue that can occur in post-transplant patients resulting in a high unmet need due to the lack of specific treatment options and the toxicity of current treatments used.
