多发性肌炎与甲状腺功能减退性肌病的鉴别诊断

目的为鉴别诊断多发性肌炎与甲状腺功能减退性肌病,对二者的异同点进行探讨。方法回顾分析12例多发性肌炎和10例甲状腺功能减退性肌病患者的临床表现、实验室检查资料。结果多发性肌炎与甲状腺功能减退性肌病在肌肉方面的临床表现相似,但急性炎症指标、自身抗体、肌肉病理检查结果多有不同,甲状腺功能检查结果明显不同。结论甲状腺功能检查有助于两病的鉴别,对于肌肉无力和肌酶升高的患者需常规检测甲状腺功能。

Polymyositis and Differential Diagnosis of Hypothyroid Myopathy

Objective To study polymyositis and differential diagnosis of hypothyroid myopathy.Methods The clinical manifestations and laboratory parameters of 12 patients with polymyositis and 10 patents with hypothyroid myopathy were analyzed and the relevant literature was reviewed.Results Hypothyroid myopathy and polymyositis show similar symptoms of muscle dysfunction and elevations of serum muscle enzymes,but can be distinguished by differences in levels of acute inflammation indexes,types of autoantibodies,muscle pathology,and thyroid function tests.Conclusion Thyroid function tests should be routinely performed in all patients with muscle weakness or elevations of muscle enzymes.
