[The clinical safety and efficacy of low dose rituximab regimen on patients with Epstein-Barr virus infection after allogeneic hematopoietic stem cell transplantation].

To retrospectively analyze the safety and efficacy of low dose rituximab regimen in patients with Epstein-Barr virus (EBV) infection after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Among 12 cases, 11 achieved complete remission (CR), 1 with partial remission (PR). Patients received 15 infusions with a median of 2.5(1-4) in each. The EBV DNA negative transformation period was 5-25 days with median 12 days. Low dose rituximab could be an alternative choice in patients with EBV infection after allo-HSCT.
