Abstract:
Objective To investigate the effect and safety of autologons bone margow-mononuclear cell (BM-MNC)transplantation after the bone marrow stimulation in patients with thromboangiitis obliterans (TAO).Methods The bone marrows of 12 patients were stimulated by an injection of the recombinant human granuloeyte-macmphage colony-stimulatory factor(GCSF)for 3-5 days.150-200 ml bone marrow was drown from the iliac spine and the autologous BM-MNC were obtained in each patients.Fifteen lower limbs of 12 patients received implantation of the autologous BM-MNC by an intramuscular iniecdon.A series of subjective indexes(including improvement of pain and cold sensation)and objeetive indexes [including increase of ankle braehial index(ABI),transcutaneons oxygen pressure(TcPO2)and improvement of foot skin ulcer] were used to evaluate the effects.Results The outcomes were evaluated after 2 months of transplantation.The pain-relief rate and the cold feeling improvement rate were 86.7%(13/15)and 93.3%(14/15)respectively.The ABI were 0.38 ±0.05 vs.0.61 ±0.14(P<0.05)before transplantation and 2 months after transplantation respectively.increased in 66.7%(10/15)limbs.The TcPO2 of the ischemic legs increased from(27.47±2.85)mm Hg to(43.53 ±8.38)mm Hg(t=-7.03,P<0.05)after the transplantation,and the improvement rate of TcPO2 was 93.3%(14/15).Skin ulcers in improved in 8/9 limbs.Twelve patients were followed up for all average period of 10 months.The patients'symptoms improved in 80.0%(12/15)limbs,as to the objective index the ABI was0.57±0.13,TcPO2 was(42.07 ±7.81)mm Hg,which improved significandy compared to before treatment(t=-5.33,-7.80,Ps<0.05).skin ulcer healing rate was 66.7%(6/9).The ischemic symptoms in 2 patients were not relieved.There WBS no mortality and high level amputation in all subjects.The complications,such as proliferative retinopathy,malitpmnt tumor,myocardial infarction,stroke or hemangioma were not found in any patients.Conclusion In patients with TAO,intramuscular transplantation of autologous BM-MNC after the bone marrow stimulation has advantages of less bone marrow aspiration,more mononuclear cell content and relatively high safety.It may be a new and effective method to alleviate symptoms and accelerate the healing of skin ulcer.
