Immune Reconstitution to CMV After HSCT: Impact of Clinical Factors and Therapy Strategies

Cytomegalovirus (CMV) remains a significant cause of morbidity and mortality after hematopoietic stem cell transplantation (HSCT). The course and outcome of CMV infection are different clinically, and the mechanism of CMV infection after transplantation has not been clarified. Reconstitution of cellular immunity after HSCT is a critical determinant of the control of CMV infection. Investigators will dynamically monitor the CMV-specific cellular immune reconstitution after HSCT，and analyze the clinical factors and therapy strategies affecting recovery of CMV-specific immunity during 1 year after HSCT.
