Abstract | OBJECTIVE: METHODS: A single-arm trial involving 10 patients with DM/PM who were either refractory to standard treatment, or had severe systemic involvement. All patients consented and underwent allogeneic MSCT. Clinical and laboratory manifestations were compared before and after MSCT. RESULTS: Improvements were seen in serum creatine kinase (CK), CK-MB, patient global assessment by visual analogue scale and muscle strength by manual muscle test in all patients, as well as improvement in interstitial lung disease in selected patients. Improvement in chronic non-healing skin ulcers was noted in one patient. Clinical responses were also seen in patients undergoing a second MSCT for recurrence of disease. CONCLUSION: MSCT appears safe and effective in drug-resistant patients with DM/PM. Larger-scale studies including a control group receiving standard treatment are needed to assess the long-term efficacy of allogeneic MSCT in refractory patients with DM/PM.
