Elevated Troponin T (TnT) in Non-acute Coronary Syndrome (ACS) Due to Dermatomyositis.

Cardiology, King Khalid University Hospital, Riyadh, SAU.
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.

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.

Objective: Older age, dermatomyositis, and specific serum autoantibodies such as anti-TIF1-γ are associated with higher cancer risk in patients with myositis. We evaluated a vast cohort of patients with myositis for the prevalence of cancer, the association to disease features, and the performance of the recent IMACS guidelines.
Methods: A retrospective cohort analysis was performed and in all cases serum autoantibodies were tested using HEp-2, immunoassays, RNA- and protein-immunoprecipitation.
Amyopathic Dermatomyositis with a Rapidly Progressing Interstitial Pneumonia.

Department of Lung Diseases and Thoracic Surgery, Pauls Stradins Clinical University Hospital, Riga, Latvia.
Background: Clinically amyopathic dermatomyositis (CADM) is a rare subtype of idiopathic inflammatory myositis often linked with the presence of autoantibodies targeting melanoma differentiation-associated protein 5 (MDA5). Patients with CADM are at increased risk of developing rapidly progressing interstitial lung disease, which significantly increases both morbidity and mortality compared to other forms of inflammatory myopathies. While there is no standardized treatment regimen, current therapeutic strategies are generally focused on combination immunosuppressive therapies.
