Cytomegalovirus( CMV) infection is one of the most common complications after lung transplantation which affects the morbidity and mortality. The transplantation society international CMV consensus group published the consensus guideline on the management, prevention, treatment and diagnostics of CMV infection. On the other hand, each lung transplant program in Japan manages the CMV infection in the lung transplant recipients according to the unique protocol. In this article, we introduce our protocol for prophylaxis and treatment for CMV infection after lung transplantation and compare it to the international guideline. We also report the conditions of CMV infections in the lung transplant recipients in our center and the outcomes of the treatment that we performed for CMV infections by our protocol.
