Abstract

Objective: Currently available treatment options for multiple sclerosis (MS) have limited efficacy and/or safety concerns. Various mesenchymal stem cells and hematopoietic stem cells have been evaluated in recent clinical trials. The present meta-analysis was conducted to assess the safety and efficacy of stem cell therapy in multiple sclerosis.

Methods: PubMed/MEDLINE, EMBASE, Cochrane Database, Scopus, and clinical trial registries were searched, and 11 RCTs were included. Quality assessment was performed using the risk-of-bias assessment 2 tool, and the random-effects model was used to estimate the effect size. Subgroup analysis, sensitivity analysis, and meta-regression were performed as applicable. PRISMA reporting guidelines were followed for reporting.

Results: A total data of 691 patients from 11 RCTs were included, and it showed that there was a greater change in EDSS score from baseline in the stem cell therapy arm as compared to the control arm (MD:-0.35; 95%CI: -0.79 to 0.08; p = 0.104), but was not significant statistically. The change in number of T2 lesions was also not statistically significant between the groups (MD:-0.75; 95%CI: -4.16 to 2.66; p = 0.619). Number of patients with at least one TEAE were comparable between the groups (OR:0.99; 95%CI: 0.61 to 1.62; p = 0.977).

Conclusion: Stem cell therapy is safe; however, it is no better than control (mostly placebo, mitoxantrone and conventional disease-modifying therapy) in the treatment of MS. Well-designed, adequately powered randomized controlled trials focusing on standardized stem cell types, routes, and dosing are essential to clarify their therapeutic role in multiple sclerosis.

造血和间充质干细胞治疗多发性硬化症的疗效和安全性:一项荟萃分析。
目的:目前可用的多发性硬化症(MS)治疗方案存在有限的疗效和/或安全性问题。各种间充质干细胞和造血干细胞在最近的临床试验中得到了评价。本荟萃分析旨在评估干细胞治疗多发性硬化症的安全性和有效性。方法:检索PubMed/MEDLINE、EMBASE、Cochrane数据库、Scopus和临床试验注册库,纳入11项rct。采用偏倚风险评估2工具进行质量评估,采用随机效应模型估计效应大小。适用时进行亚组分析、敏感性分析和元回归分析。报告遵循了PRISMA报告准则。结果:共纳入11项rct的691例患者的数据,结果显示干细胞治疗组的EDSS评分与基线相比有更大的变化(MD:-0.35;95%CI: -0.79 ~ 0.08;P = 0.104),但差异无统计学意义。两组间T2病变数量的变化也无统计学意义(MD:-0.75;95%CI: -4.16 ~ 2.66;p = 0.619)。两组之间至少发生一次TEAE的患者数量具有可比性(OR:0.99;95%CI: 0.61 ~ 1.62;p = 0.977)。结论:干细胞治疗是安全的;然而,在多发性硬化症的治疗中,它并不比对照组(主要是安慰剂、米托蒽醌和传统的疾病改善疗法)更好。精心设计、充分支持的随机对照试验,重点关注标准化的干细胞类型、途径和剂量,对于阐明它们在多发性硬化症中的治疗作用至关重要。普洛斯彼罗注册号:CRD42023457808。
