[Preliminary Clinical Efficiency of Autologous Peripheral Blood Mononuclear Cells for Treating Critical Limb Ischemia of Thromboangiitis Obliterans].

OBJECTIVE: To evaluate the long-term clinical effect of autologous peripheral blood mononuclear cells (PB-MNC) on critical limb ischemia (CLI) in patients with thromboangiitis obliterans (TAO) patients.

METHODS: The clinical data of 22 patients with CLI caused by TAO from July 2004 to May 2013 were analyzed retrospectively, 22 patients were divided into 2 groups; out of them 12 cases in one group were treated with granulocyte colony-stimulating factor (G-CSF)-mobilized autologous peripheral blood mononuclear cells (auto-PBMNC group), 10 cases in another group received conservative treatment (CT group). The log-rank test was used to compare the long-term outcomes in auto-PBMNC group and CT group.

RESULTS: The wound healing rate (P=0.016) and CLI-free rate (P=0.013) were significantly higher in PB-MNC group compared with that in CT group. No difference was found in amputation rates between the 2 groups (major amputation: P=0.361, minor and major amputation: P=0.867). No patients died or no serious adverse events occurred during the follow-up period.

CONCLUSION: The auto-PBMNC therapy can significantly promote the wound healing, and protect against CLI in TAO patients, but the risk of amputation is not low in comparison with conservative treatment.
