摘要:

背景:近年来,应用干细胞治疗免疫性疾病已成为研究热点,国内外有关脐血间充质干细胞移植治疗多发性肌炎/皮肌炎的报道较少。

目的:观察脐血间充质干细胞移植治疗多发性肌炎/皮肌炎患者血清干扰素γ、白细胞介素4、白细胞介素17水平变化,探讨Th细胞因子在多发性肌炎/皮肌炎发生发展中的免疫机制。
方法:81例多发性肌炎/皮肌炎患者,其中44例为常规治疗组,给予糖皮质激素联合免疫抑制剂治疗,37例为脐血间充质干细胞移植组,静脉输注脐血间充质干细胞(3.5-5.2)×107,用药方案与常规治疗组相同。随访治疗后1,3,6 个月肌酸激酶、肌力变化及治疗后3,6个月肺部影像学改变,并在治疗前及治疗后3,6个月检测移植组Th细胞因子水平。
结果与结论:①两组治疗后1,3,6个月与治疗前比较肌酸激酶值明显下降、肌力评分明显增高(均P < 0.001);移植组治疗后各时间点肌酸激酶值较常规治疗组低、肌力评分较常规治疗组高(均P < 0.001)。②脐血间充质干细胞移植治疗能明显改善肺部影像学异常,且安全性好。③移植治疗后6个月干扰素γ水平显著升高,而白细胞介素4水平显著下降(均P < 0.01);移植治疗后 3,6 个月白细胞介素17水平显著下降(均P < 0.01)。④移植治疗后6个月白细胞介素4、白细胞介素17水平与肌酸激酶水平成正相关(r=0.467和0.488,均P < 0.05);干扰素γ水平与肌酸激酶水平无明显相关(r=0.213,P > 0.05)。结果表明给予糖皮质激素及免疫抑制剂治疗同时,联合脐血间充质干细胞移植治疗多发性肌炎/皮肌炎安全、有效,可调节多发性肌炎/皮肌炎患者免疫网络效应、改善免疫耐受。

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.
