Objective: To analyze the incidence of cytomegalovirus infection and related risk factors after allogeneic hematopoietic cell transplantation and to develop a rational strategy for the preemptive treatment of CMV infection.
Methods: The clinical data of 398 patients undergoing allogeneic hematopoietic cell transplantation from December 2011 to December 2014 were analyzed retrospectively by using a Kaplan Meier analysis and Logistics model.
Results: Out of 398 patients 233 developed post-transplant CMV infection (58.5%). Univariate analysis showed that HLA mismatch, ATG administration, acute graft versus host disease (aGVHD), using prednisone ≥ 1 mg/kg body weight or equivalent were associated with increase of CMV infection. Multivariate analysis showed that HLA mismatch (HR = 2.765, P = 0.000), ATG administration (HR = 3.866, P = 0.000), using prednisone ≥ 1 mg/kg body weight or equivalent (HR = 4.767, P = 0.000) also were associated with increase of CMV infection.
Conclusion: HLA mismatch, ATG administration, using prednisone ≥ 1 mg/kg are risk factors for CMV reaction.
