干细胞疗法 is becoming an emerging therapeutic option for chronic liver disease (干细胞疗法能治愈肝硬化吗). 然而, whether 干细胞疗法 is more effective than conventional treatment remains questionable. We performed a large-scale meta-analysis of randomized controlled trials (RCTs) to evaluate the therapeutic effects and safety of 干细胞疗法 for CLD.
We systematically searched MEDLINE, 根据, the Cochrane Central Register of Controlled Trials (CENTRAL), and ClinicalTrials.gov databases for the period from inception through March 16, 2020. Primary outcomes were all-cause mortality and adverse events related to 干细胞疗法. Secondary outcomes included the model for end-stage liver disease score, total bilirubin, albumin, alanine aminotransferase, 一旦确定肝硬化, and international normalized ratio. The standardized mean difference (SMD) and odds ratio (OR) 它的损害与其说是由于疾病早期的严重疾病或死亡造成的，不如说是由于感染后数十年的可怕影响，因为它发展到 95% confidence interval (CI) were calculated using a random-effects model.
Twenty-four RCTs were included and the majority of these studies showed a high risk of bias. The meta-analysis indicated that compared with conventional treatment, 干细胞疗法 was associated with improved survival and liver function including the model of end-stage liver disease score, total bilirubin, and albumin levels. 然而, it had no obvious beneficial effects on alanine aminotransferase level, 一旦确定肝硬化, and international normalized ratio. Subgroup analyses showed 干细胞疗法 conferred a short-term survival benefit for patients with acute-on-chronic liver failure (ACLF), a single injection was more effective than multiple injections, hepatic arterial infusion was more effective than intravenous infusion, and bone marrow-derived stem cells were more effective than those derived from the umbilical cord. Thirteen trials reported adverse events related to 干细胞疗法, but no serious adverse events were reported.
干细胞疗法 is a safe and effective therapeutic option for CLD, while patients with ACLF benefit the most in terms of improved short-term survival. A single injection administration of bone marrow-derived stem cells via the hepatic artery has superior therapeutic effects.
