Abstract

Aim To evaluate the efficacy of stem cell therapy from different sources on the ankle-brachial index, wound closure percentage, and wound closure time in the treatment of diabetic foot ulcers (DFUs). Methods A literature search was conducted in PubMed, Embase, Cochrane Library's Central Register of Controlled Trials, and Web of Science, extending through June 29, 2023. Quality evaluation was done using the Cochrane's bias risk assessment tool (RoB 2.0). Employing a Bayesian approach, the statistical computations was executed with the JAGS software, leveraging the gemtc 0.8-2 and rjags 4-10 libraries, within the R environment 4.1.2. The included interventions came from peripheral blood, bone marrow, placenta, umbilical cord blood, adipose tissue, or others. Result A preliminary search identified 2286 articles, of which 23 randomized controlled trials met the inclusion criteria and were ultimately included. The analysis findings indicated that mesenchymal stem cells derived from the umbilical cord (HUCMSCs) led to a notable enhanced the ankle-brachial index in patients with DFUs compared to standard treatment (MD: 0.2; 95% CI [0.01, 0.36]). HUCMSCs were found to be the optimal therapeutic approach for enhancing the ankle-brachial index (SUCRA = 82.7%). Research on the wound closure percentage revealed that compared to platelet-rich plasma (PRP), processed microvascular tissue (PMVT), peripheral blood stem cells (PBSCs), microfragmented adipose tissue (MFAT), autologous bone marrow-derived stem cell therapy (ABMSCT), adipose-derived stem cells (ASCs), and dehydrated human umbilical cord allograft (EpiCord), Huoxue Shengji Decoction (HXSJD) + ABMSCT (H_Group_hematopoietic) significantly increased the wound closure percentage in DFU patients ( P < 0.05). According to the SUCRA ranking, HXSJD + ABMSCT was the best therapeutic method to increase the percentage of wound closure (SUCRA = 93.8%). Conclusion This study employed a network meta-analysis method, combining direct and indirect comparisons, to analyze the latest clinical data and concluded that umbilical cord mesenchymal stem cells and the combination of HXSJD + autologous bone marrow hematopoietic stem cell treatment as adjunctive therapies for DFUs may have beneficial effects. Future research needs to focus on this.
