Abstract:

BACKGROUND: Haploidentical hematopoietic stem cell transplantation is currently the mainstream mode of transplantation in China, but its widespread development is restricted by the higher incidence of graft-versus-host disease and implantation failure as compared with HLA identical hematopoietic stem cell transplantation. In order to solve these two problems, co-transplantation of mesenchymal stem cells and hematopoietic stem cells is used in some transplant centers to promote hematopoietic stem cell transplantation, and to reduce the incidence of graft-versus-host disease. Studies have shown that mesenchymal stem cells can promote the repair of liver cells in liver cirrhosis and hepatitis patients. It is unclear whether co-transplantation of mesenchymal stem cells and hematopoietic stem cells can prevent acute drug-induced liver injury.
OBJECTIVE: To investigate the preventive and protective effects of infusion of umbilical cord blood mesenchymal stem cells on acute drug-induced liver injury after conditioning in haploidentical hematopoietic stem cell transplantation. 
METHODS: Clinical data of patients who underwent haploidentical hematopoietic stem cell transplantation from January 2010 to August 2017 was retrospectively analyzed. Eight cases were transfused with umbilical cord blood mesenchymal stem cells 1×106/kg within 4-6 hours before transfusion of hematopoietic stem cells. Seventeen-seven cases in the control group were not given umbilical cord blood mesenchymal stem cells. The changes of liver function indicators and treatment outcomes at 1 day, 2 weeks and 4 weeks after transplantation conditioning were observed. The study protocol was approved by the ethics committee of the First Affiliated Hospital of Xi’an Jiao Tong University with the approval No. 2016(20). Written informed consent was obtained prior to the initiation of the study. 
RESULTS AND CONCLUSION: (1) Patients in both groups had abnormalities in the biomedical indicators of liver function to different extent. These indicators peaked at 2 weeks post preconditioning, and then became normal after 4 weeks. (2) The levels of alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, transglutaminase, and direct bilirubin were significantly lower in the observation group than the control group at 1 day and 2 weeks after transplantation conditioning (P < 0.05). (3) There were no adverse reactions such as fever, blood pressure increase/decrease, arrhythmia and hemolysis in the two groups during the infusion of hematopoietic stem cells and umbilical cord blood mesenchymal stem cells. These findings reveal that co-transfusion of umbilical cord blood mesenchymal stem cells during haploidentical hematopoietic stem cell transplantation may reduce acute drug-induced liver injury after transplantation conditioning, and it needs to be further investigated duo to limit numbers of patients.
