Abstract:
OBJECTIVE:Systemic lupus erythematosus (SLE) is an autoimmune disease with multi-organ involvement and several typical autoantibodies. Mesenchymal stem cells (MSC) are multipotent stem cells with low immunogenicity that can differentiate into various kinds of cells, such as bone, cartilage, fat and skin tissue. MSC have immunomodulatory and reparative properties through interactions with immune cells. MSC have been used in the treatment of refractory SLE and lupus nephritis patients for more than ten years. Most clinical studies were self-controlled studies and only a few were randomized controlled trials. The objective of this study was to use meta-analysis method to evaluate the efficacy and safety of MSC treatment in SLE patients.
METHODS:The PubMed, Cochrane Library, Wanfang and VIP databases were searched for published randomized controlled trials and self-controlled studies before June 1, 2018. The search terms included the Chinese and English versions of mesenchymal stem cells, Mesenchymal Stromal Cells [Mesh], systemic lupus erythematosus, lupus, Lupus Erythematosus, Systemic [Mesh]. Two authors independently screened the literatures, assessed the quality of the studies and collected data according to the inclusion and exclusion criteria. The endpoints were the SLE disease activity index, 24 h urine protein and complement C3. Meta-analysis was performed with the Revman 5.3 software according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standard.
RESULTS:Eight studies involving 213 patients were included and three of the studies were randomized controlled trials with 66 patients involved. The MSC group showed that the SLE disease activity index decreased significantly [standard mean difference (SMD)=-1.76, 95% confidence interval (CI): -2.00 to -1.51, P<0.001), the 24 h urine protein decreased significantly (SMD=-1.74, 95%CI: -2.46 to -1.03, P<0.001), as well as the complement C3 increased significantly (SMD=1.28, 95%CI: 0.93 to 1.62, P<0.001). Four studies reported adverse events including fever, diarrhea and headache during the infusion.
CONCLUSION:Current evidences showed that MSC could improve the disease activity, proteinuria and hypocomplementemia in SLE patients. Large scale and high-quality randomized controlled trials are required to validate the efficacy and safety of MSC treatment in SLE patients.
