Popis: | Objective. SSc causes intractable ischaemic ulcers. To avoid major amputation, we examined the safety and efficacy of therapeutic vascular angiogenesis for digital ulcers due to SSc. Methods. A single-centre, open-label pilot study was conducted in patients with an ischaemic digital ulcer [n = 40, mean age 65 years (S.D. 8), Rutherford class III-5 or III-6) due to lcSSc (n = 11) or arteriosclerosis obliterans (ASO; n = 29). Bone marrow mononuclear cells (0.45.1 10 10 cells in total) were administered into the ischaemic limbs. We evaluated short-term safety and efficacy by means of a pain scale, 99m Tc-tetrofosmin scintigraphy and transcutaneous oxygen tension (TcPO2) before and 4 weeks after treatment. Also, the 2-year outcome was compared. Results. There was a case of amputation in each group within 4 weeks after therapy. The pain scale significantly decreased in both groups [lcSSc 93 mm (S.D .9 ) to 11 ( S.D. 16), P < 0.01; ASO 77 mm (S.D. 22) to 16 (S.D. 13), P < 0.01] and TcPO2 significantly improved [lcSSc 9.0 mmHg (S.D .9 ) to 35 ( S.D. 14), P < 0.01; ASO 18 mmHg (S.D. 10) to 29 (S.D. 21), P < 0.05). At the 2-year follow-up, the limb amputation rate was 9.1% in lcSSc and 20.7% in ASO (P = 0.36), while the recurrence rate was 18.2% in lcSSc and 17.2% in ASO (P = 0.95). All-cause mortality was 27.3% in lcSSc and 17.2% in ASO (P = 0.65). Conclusion. In patients with lcSSc, bone marrow mononuclear cell implantation provides clinical benefit and is safe, without major adverse reactions, and may become an effective strategy.
