Long-term efficacy of autologous cell therapy, repeated PTA and conservative treatment in people with diabetes and chronic limb-threatening ischaemia.
Aims: Data about long-term clinical outcomes of revascularization procedures, especially for autologous cell therapy (ACT), in diabetic patients with chronic limb-threatening ischaemia (CLTI) are lacking. The aim of our study was to compare the mortality and amputation rates in patients with diabetic foot ulcers (DFU) and CLTI treated by ACT with patients treated by repeated percutaneous transluminal angioplasty (re-PTA) and those treated conservatively.
Materials and methods: One-hundred and thirty patients with DFU and CLTI (defined as transcutaneous oxygen pressure-TcPO2 <30 mmHg after unsuccessful standard revascularization) treated in our foot clinic over 9 years were enrolled in the study. Forty-five patients were treated by ACT, 43 patients underwent re-PTA, and 42 patients were treated conservatively and formed the control group. Overall survival, amputation-free survival (AFS) and major amputation rate were assessed over a 7-year follow-up period.
Results: Baseline demographic characteristics and comorbidities were similar between groups. However, patients in ACT and control groups had significantly worse baseline angiograms in accordance with Graziani and GLASS (infrapopliteal region) classifications than the re-PTA group (both p < 0.001), but there were no differences in baseline values of TcPO2 between groups. AFS in the ACT and re-PTA groups were significantly longer compared to control (both p < 0.001). The rate of major amputation was significantly lower in both active groups (both p < 0.001). The re-PTA group showed significantly longer overall survival compared to the control group (p < 0.001), but there was no significant difference between ACT and control groups (p = 0.063) and ACT and re-PTA groups (p = 0.081) in this parameter.
Conclusions: Our study showed significantly longer AFS and lower major amputation rates in patients treated by ACT and re-PTA in contrast to patients treated conservatively. Overall survival was significantly longer only in the re-PTA group. ACT was shown to be effective in long-term limb salvage in people with no-option CLTI.
期刊介绍：
Diabetes, Obesity and Metabolism is primarily a journal of clinical and experimental pharmacology and therapeutics covering the interrelated areas of diabetes, obesity and metabolism. The journal prioritises high-quality original research that reports on the effects of new or existing therapies, including dietary, exercise and lifestyle (non-pharmacological) interventions, in any aspect of metabolic and endocrine disease, either in humans or animal and cellular systems. ‘Metabolism’ may relate to lipids, bone and drug metabolism, or broader aspects of endocrine dysfunction. Preclinical pharmacology, pharmacokinetic studies, meta-analyses and those addressing drug safety and tolerability are also highly suitable for publication in this journal. Original research may be published as a main paper or as a research letter.
