[A clinical analysis of hepatic veno-occlusive disease after hematopoietic stem cell transplantation].

Objective: To analyze the outcome and the prognostic factors of hepatic veno-occlusive disease (HVOD) after hematopoietic stem cell transplantation (HSCT). Methods: A total of 797 patients receiving HSCT were analyzed retrospectively. The prophylaxis regimen of HVOD in the First Affiliated Hospital of Guangxi Medical University consisted of low molecular weight heparin and lipoprostaglandin E1 (PGE1). Results: Fifty-nine patients (7.4%) developed HVOD at 3-49 days after HSCT (median 12 days). Age younger than 15 years at transplant(HR= 6.47, P<0.001), busulphan conditioning (HR=6.40, P<0.001), thalassemia major (HR=6.35, P<0.001), allogeneic transplantation (HR=7.74, P=0.005) were univariate risk factors for HVOD. Multivariate analyses suggested that thalassemia major and busulphan conditioning were independently correlated with the development of HVOD. Conclusion: Thalassemia major and busulphan conditioning are independent risk factors for HVOD after HSCT.
