Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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 collect peripheral blood at 1 month, 2 month, 3 month, and 6 month after HSCT from the participated patients, and dynamically monitor the CMV-specific T and NK cellular immune reconstitution.

Investigators will also analyze the clinical factors and therapy strategies affecting recovery of CMV-specific immunity during 1 year after HSCT.
