Autologous bone marrow infusion via portal vein combined with splenectomy for decompensated liver cirrhosis: A retrospective study

BACKGROUNDIn a previous study, autologous bone marrow infusion (ABMI) was performed in patients with decompensated liver cirrhosis (DLC) and acquired immunodeficiency syndrome and achieved good results, but whether splenectomy affected outcome was unclear.AIM To investigate the efficacy of ABMI combined with splenectomy for treatment of DLC.METHODSEighty-three patients with DLC were divided into an intervention group (43 cases) and control group (40 cases) according to whether splenectomy was performed. The control group was treated with ABMI through the right omental vein, and the intervention group was additionally treated with splenectomy.RESULTSAfter ABMI, the prothrombin time, serum total bilirubin levels, ascites volume and model for end-stage liver disease score in both groups were significantly lower, while the albumin levels were significantly higher than before ABMI (P < 0.01), but there were no significant differences between the groups (P > 0.05). After ABMI, the white blood cell and platelets counts in both groups were significantly higher than before ABMI (P < 0.01), and the counts in the intervention group were significantly higher than in the control group (P < 0.01). After ABMI the CD4(+) and CD8(+) T cell counts in both groups were significantly higher than before ABMI (P < 0.01). The CD8(+) T cell counts in the intervention group increased continuously and the increase had a shorter duration compared with control group.CONCLUSIONABMI through the portal vein in patients with DLC can significantly improve liver synthetic and secretory functions, and splenectomy promotes improvement of bone marrow hematopoietic and cellular immune functions.
