Therapeutic effect of mesenchymal stem cells on acute-on-chronic liver failure： A Meta-analysis
-
摘要:
目的 系统评价间充质干细胞（MSC）治疗慢加急性肝衰竭的有效性和安全性。 方法 本研究根据PRISMA指南完成，PROSPERO注册号：CRD42024517851。计算机检索PubMed、Embase、万方数据库、维普数据库和中国知网、中国生物医学数据库、Cochrane图书馆，搜集建库至2023年11月1日发表的有关于MSC治疗慢加急性肝衰竭的随机对照研究（RCT）、队列研究，根据纳入和排除标准对文献进行筛选，并对文献进行数据提取和质量评估，采用RevMan 5.3软件进行Meta分析。 结果 共纳入11篇文献，803名研究对象进行本次Meta分析。结果表明，MSC治疗可提高ACLF患者8周生存率（OR=2.71，95%CI：1.58～4.67，P=0.000 3）、12周生存率（OR=2.24，95%CI：1.36～3.69，P=0.001）、24周生存率（OR=2.09，95%CI：1.37～3.17，P=0.000 6）、48周生存率（OR=2.09，95%CI：1.29～3.40，P=0.003）；可降低12周MELD评分（MD=-3.27，95%CI：-6.07～-0.48，P=0.02）、24周MELD评分（MD=-2.24，95%CI：-3.16～-1.33，P<0.000 01）；可降低治疗后4周的TBil水平（MD=-36.86，95%CI：-48.72～-25.01，P<0.000 01）；提高治疗后4周、24周的Alb水平（MD=2.11，95%CI：0.62～3.61，P=0.006；MD=3.54，95%CI：2.06～5.02，P<0.000 01）。共6篇文献对不良事件进行了评价，无严重不良事件发生。 结论 MSC治疗安全性良好，可提高患者生存率，一定程度上改善肝功能，具有临床应用价值。 Abstract:Objective To systematically evaluate the efficacy and safety of mesenchymal stem cells （MSC） in the treatment of acute-on-chronic liver failure （ACLF）. Methods This study was conducted according to PRISMA guidelines， with the PROSPERO registration number of CRD42024517851. PubMed， Embase， Wanfang Data， VIP， CNKI， CBM， and the Cochrane Library were searched for randomized controlled trials （RCT） and cohort studies on MSC in the treatment of ACLF published up to November 1， 2023， and the articles were screened according to inclusion and exclusion criteria. After data extraction and quality assessment， RevMan 5.3 software was used to perform the Meta-analysis. Results A total of 11 articles involving 803 subjects were included in this meta-analysis. The results showed that for the patients with ACLF， MSC could improve 8-week survival rate （odds ratio ［OR］=2.71， 95% confidence interval ［CI］： 1.58 — 4.67， P=0.000 3）， 12-week survival rate （OR=2.24， 95%CI： 1.36 — 3.69， P=0.001）， 24-week survival rate （OR=2.09， 95%CI： 1.37 — 3.17， P=0.000 6）， and 48-week survival rate （OR=2.09， 95%CI： 1.29 — 3.40， P=0.003） and reduce 12-week Model for End-Stage Liver Disease （MELD） score （mean difference ［MD］=-3.27， 95%CI： -6.07 to -0.48， P=0.02） and 24-week MELD score （MD=-2.24， 95%CI： -3.16 to -1.33， P<0.000 01）； it could also reduce the level of total bilirubin after 4 weeks of treatment （MD=-36.86， 95%CI： -48.72 to -25.01， P<0.000 01） and increase 4-week albumin level （MD=2.11， 95%CI： 0.62 — 3.61， P=0.006） and 24-week albumin level （MD=3.54， 95%CI： 2.06 — 5.02， P<0.000 01）. Adverse events were evaluated in 6 studies， with no serious adverse events. Conclusion MSC have a good safety in treatment and can improve the survival rate of patients and enhance liver function to some extent， and therefore， it holds promise for clinical application. -
