 Dermatomyosities, DM, is a rare autoimmune disorder characteristic by skin rashes and muscle weakness. It is caused by the body's immune system attacking its own tissues. Recently, researchers have discovered that some patients with DM also have antibodies against certain proteins, which can help doctors identify the type of DM they are dealing with. In this study, researchers looked at the prevalence of these antibodies in patients with DM in Taiwan. They found that 78% of the patients had antibodies against melanoma differentiation associated protein 5, NDA5, or transcription intermediary factor 1-gamma, TIF 1-gamma. These antibodies were more common in patients with NDA5 antibodies than in those with anti-TIF 1-gamma antibodies. Additionally, patients with NDA5 antibodies were more likely to develop dysphagia, a condition where it becomes difficult to swallow food. Patients with anti-TIF 1-gamma antibodies were more likely to develop interstitial lung disease. This article was authored by W. Y. Ting Liu and Chao Chun Yang. We are article.tv.
