| Popis: | The clinical features of patients with critical limb ischemia (CLI) who responded to angiogenesis using autologous peripheral blood mononuclear cell transplantation (PB-MNC) have not yet been fully characterized, and there are no useful predictors to judge the curative effect in the early period after PB-MNC. This study sought to clarify the clinical features and predictors in patients with CLI who were successfully treated using PB-MNC. 30 consecutive patients [arteriosclerosis obliterans: 24 patients, thromboangiitis obliterans: 6 patients] who were diagnosed with major amputation despite maximal medical therapy were enrolled in this study. The study endpoint was major amputation within 3 months after PB-MNC. The collected data were evaluated for correlation between patients with and without major amputation within 3 months after PB-MNC. Six patients underwent major amputation and 1 patient underwent minor amputation. In the patients with major amputation, transcutaneous oxygen tension before PB-MNC and transplanted CD34-positive cells were lower than those of patients without major amputation. In the patients with amputation, interleukin-6 (IL-6) continued to increase after the first PB-MNC, and basic fibroblast growth factor (bFGF) decreased within 3 days after the first PB-MNC. PB-MNC was useful for the patients who were managed for inflammation and who had revascularization of the upper-popliteal arteries and two of the infra-popliteal arteries by endovascular and/or surgical revascularization. Variation in IL-6 and bFGF in the early period after PB-MNC could be useful predictors for the requirement of amputation within 3 months after PB-MNC. |
