[Effects of Hepatovirus B Infection on the Hematopoietic Stem Cell Collection and Implantment in Lymphoma Patients Received Autologous Peripheral Blood Hematopoietic Stem Cell Transplantation].

OBJECTIVE: To investigate the effect of hepatovirus B(HBV) infection on the hematopoietic stem cell collection and implantment in lymphoma patients received autologous peripheral hematopoietic blood stem cells transplantation.

METHODS: Clinical data of 40 lymphoma patients who received autologous peripheral hematopoietic blood stem cell transplantation between January 2006 and October 2014 was analyzed retrospectively. Among 40 patients with lymphoma 8 patients combined with HBV infection were prophylacticly given nucleoside analogues and 32 patients without HBV infection. The counts of mononuclear cells(MNC) and CD34 positive cells were collected and the hematopoietic reconstitution as well as overall survival rates and progress-free survival rates were detected and counted between patients with or without HBV infection.

RESULTS: The counts of MNC and CD34 positive cells in all patients were standard, and there was no significant difference between patients with or without HBV infection. HBV wasn't reactivated among the 8 patients with HBV infection. The 1, 3 and 5 years' overall survival rates and progress-free survival rates of patients with HBV infection were 100%, 85.7%, 57.1% and 100%, 80%, 53%, respectively and the 1,3 and 5 years' overall survival rates and progress-free survival rates of patients without HBV infection were 100%, 88.9%, 82.1% and 90%, 90%, 90%, respectively.

CONCLUSION: HBV infection may have no effect on the collection of stem cells and hematopoietic reconstitution. Prophylactic use of nucleoside analogues can effectively prevent the hepatitis B virus reactivation, moreover had no effect on the collection and hematopoietic reconstitution.
