Abstract: In recent years, there have been significant advances in the diagnosis and treatment of cytomegalovirus (CMV) infection in solid organ transplant (SOT) recipients, including diagnostic method and anti-CMV drugs. These advancements have had a positive impact on the management of CMV infection in SOT recipients. To further standardize the management of CMV infection after kidney transplantation in China, Branch of Organ Transplantation of Chinese Medical Association organized a multidisciplinary group of experts in relevant fields. They referred to the ‘Diagnosis and Treatment Guidelines for Cytomegalovirus Infection in Solid Organ Transplant Recipients in China (2016 edition)’ and the latest published literature and guidelines, resulting in the development of the ‘Clinical Diagnosis and Treatment Guidelines for Cytomegalovirus Infection in Kidney Transplant Recipients in China (2023 edition)’. The updated guideline includes CMV epidemiology, research progress on the risk factors and universal prevention of CMV infection, the definition for CMV infection, detailed diagnostic criteria for CMV viremia and CMV disease, as well as an introduction to new anti-CMV drugs.
