Abstract

We report a rare case of overlap syndrome between anti-MDA5-positive dermatomyositis (DM) and rheumatoid arthritis (RA) in a 65-year-old woman. Initially diagnosed with RA, the patient later developed characteristic DM manifestations including characteristic DM rash, generalized weakness, poor appetite, and unintentional weight loss. Laboratory findings revealed elevated muscle enzymes, positive anti-melanoma differentiation-associated gene 5 (MDA5) antibody and anti-Ro52 antibodies, and increased anti-citrullinated protein antibodies. The patient showed significant improvement following combination therapy with prednisone and mycophenolate mofetil, highlighting the importance of early recognition and appropriate management of this rare overlap syndrome.

抗mda5阳性皮肌炎合并类风湿关节炎1例
我们报告一个罕见的病例重叠综合征之间的抗mda5阳性皮肌炎(DM)和类风湿关节炎(RA)在65岁的妇女。患者最初诊断为RA,后来出现特征性DM表现,包括特征性DM皮疹、全身无力、食欲不振和体重意外下降。实验室结果显示肌肉酶升高,抗黑色素瘤分化相关基因5 (MDA5)抗体和抗ro52抗体阳性,抗瓜氨酸化蛋白抗体升高。在强的松和霉酚酸酯联合治疗后,患者表现出明显的改善,突出了早期识别和适当处理这种罕见重叠综合征的重要性。

期刊介绍: Clinical, Cosmetic and Investigational Dermatology is an international, peer-reviewed, open access journal that focuses on the latest clinical and experimental research in all aspects of skin disease and cosmetic interventions. Normal and pathological processes in skin development and aging, their modification and treatment, as well as basic research into histology of dermal and dermal structures that provide clinical insights and potential treatment options are key topics for the journal. Patient satisfaction, preference, quality of life, compliance, persistence and their role in developing new management options to optimize outcomes for target conditions constitute major areas of interest. The journal is characterized by the rapid reporting of clinical studies, reviews and original research in skin research and skin care. All areas of dermatology will be covered; contributions will be welcomed from all clinicians and basic science researchers globally.
