Utilising bioinformatics and systems biology methods to uncover the impact of dermatomyositis on interstitial lung disease.
Clin Exp Rheumatol
January 2025
Department of Oncology and Vascular Interventional Radiology, Zhongshan Hospital Xiamen University, School of Medicine, Xiamen University, Xiamen, Fujian, China.
Objectives: Dermatomyositis (DM) is frequently associated with interstitial lung disease (ILD); however, the molecular mechanisms underlying this association remain unclear. This study aimed to employ bioinformatics approaches to identify potential molecular mechanisms linking DM and ILD.
Methods: GSE46239 and GSE47162 were analysed to identify common differentially expressed genes (DEGs).
Elevated Troponin T (TnT) in Non-acute Coronary Syndrome (ACS) Due to Dermatomyositis.

Troponin is a highly specific biomarker for myocardial injury. It plays a critical role in the diagnosis of acute coronary syndrome (ACS). However, elevated troponin levels are not exclusively due to cardiac ischemia and may be observed in many non-cardiac conditions, including inflammatory myopathies.

Objective: Juvenile dermatomyositis (JDM) is a complex autoimmune disease, and its pathogenesis remains poorly understood. Building upon previous research on the immunological and inflammatory aspects of JDM, this study aims to investigate the role of pyroptosis in the pathogenesis of JDM using a comprehensive bioinformatics approach.
Methods: Two microarray datasets (GSE3307 and GSE11971) were obtained from the Gene Expression Omnibus database, and a list of 62 pyroptosis-related genes was compiled.
Safety and Efficacy of Long-term Use of Infliximab in Severe Juvenile Dermatomyositis - 12 Years of Follow-up.

Juvenile dermatomyositis with emphasized vasculopathy is rare, but the most severe form of the disease, with a poor prognosis with relapsing and chronic course or, in some cases, lethal outcome. We present a case of a 19-year-old Caucasian female, who developed severe acute juvenile dermatomyositis with emphasized multisystem vasculopathy, including retinal vasculopathy and maculopathy (cotton-wool spots, retinal hemorrhages, macular edema) at the age of 8. Due to no response to standard treatment protocols and rapid worsening of clinical symptoms and laboratory findings, a TNF inhibitor (infliximab) was introduced after the third week of treatment resulting in complete normalisation of muscle enzyme levels and complete resolution of eye changes within the next 2 weeks with a gradual general recovery.
