Mesenchymal stem cells improve transplant renal function from donation after citizens death: a short-term clinical trials / 中华器官移植杂志

ABSTRACT

Objective To investigate the efficacy and safety of mesenchymalstem cells (MSCs)in improving the renal transplantation functional recovery of donation after citizens death (DCD)derived renal donors.Methods A retrospective analysis of 97 cases of DCD renal transplantation was performed in our center from July 2011 to December 2016.Among them,50 cases were treated with MSCs (the treatment group) and 47 cases without MSCs (the control group).In the treatment group,the umbilical cord stem cell suspension (50 mL,approximately 1 106/kg weight) was infused before vascular patency and 1 week,2 weeks,and 3 weeks after renal transplantation.Postoperative renal function within 3 months of recovery,delayed graft function (DGF) incidence and duration,the incidence of pulmonary infection,acute rejection and surgical complications were analyzed.Resuts The incidence rate of DGF and duration in the treatment group were 16.0％ and (14.42 ± 3.95) days,and those in the control group were 27.7％ and (17.85 ± 6.25) days respectively,and there were statistically significant difference.The incidence of acute rejection in the treatment group and the control group was 12.0 and 21.3％ respectively with the difference being statistically significant.The incidence rate of pulmonary infection in the treatment group and control group was 10％ and 12.7％respectively with the different being not statistically significant.Comparison of eGFR at 1st,1st month and 3rd month after operation showed that the eGFR in the control group was statistically significantly lower than that in the treatment group at 1st and 3rd month,but there was no significant difference in eGFR at 1st week between the two groups.There was no significant difference in the surgical complications between the two groups.Conclusion In the treatment group,the incidence rate of DGF was lower,and DGF duration was shorter than in the control group.The acute rejection rate in the control group increased significantly,but there was no significant difference in pulmonary infection and surgical complications between two groups.The recovery trend of renal function in the treatment group was better than that in the control group.
