Abstract:

BACKGROUND: In recent years, the application of stem cells to treat autoimmune diseases has become a hot spot. But, studies on umbilical cord blood mesenchymal stem cells transplantation for the treatment of polymyositis/dermatomyositis are rarely reported.

OBJECTIVE: To explore the immunologic mechanism of Th cytokines on the occurrence and development of polymyositis/dermatomyositis by observing the changes in serum interferon-γ, interleukin-4 and interleukin-17 in patients after umbilical cord blood mesenchymal stem cells transplantation.
METHODS: Eighty-one polymyositis/dermatomyositis patients were selected and divided into conventional therapy group (n=44) undergoing glucocorticoid and immunosuppressants therapy and cell transplantation group (n=37) undergoing intravenous infusion of umbilical cord blood mesenchymal stem cells at a density of (3.5-5.2 )×107. Dosing regimen was same in the two groups. After follow-up of 1, 3, 6 months, the changes of creatine kinase and myodynamia were evaluated; after follow-up of 3 and 6 months, lung imaging was evaluated; in the cell transplantation group, interferon-γ, interleukin-4 and interleukin-17 levels were detected before treatment and at 3 and 6 months after treatment.
RESULTS AND CONCLUSION: At 1, 3, 6 months after treatment, the creatine kinase level was significantly decreased, and the muscle force grade was significantly increased in both groups (both P < 0.001). Compared with the conventional therapy group, the creatine kinase level was lower and the muscle force grade was higher in the cell transplantation group (both P < 0.001). Results from lung imaging test showed a remarkable improvement after cell transplantation, and it indicated that umbilical cord blood mesenchymal stem cells transplantation had good stability. At 6 months after transplantation, the level of interferon-γ was significantly increased, while the interleukin-4 level was decreased significantly (both P < 0.01); at 3, 6 months after cell transplantation, the levels of interleukin-17 were significantly decreased (P < 0.01). Levels of interleukin-4 and interleukin-17 were positively correlated with the level of creatine kinase at 6 months after cell transplantation (r=0.467, 0.488, both P < 0.05), but there was no obvious correlation between the levels of interferon-γ and creatine kinase (r=0.213, P > 0.05). These findings indicate umbilical cord blood mesenchymal stem cells transplantation combined with glucocorticoid and immunosuppressants therapy can adjust immune network effects and improve the immune tolerance in polymyositis/dermatomyositis patients, which is safe and effective.
