Dermatomyositis (DM) is an idiopathic inflammatory myopathy involving proximal muscle weakness and skin rash. An associated increased risk of malignancy is well established.1 The most frequent malignancies are related to the ovary, endometrium, lung, gastrointestinal tract, prostate, breast and lymphatics.2 On rare occasions, DM has been reported with certain types of non-Hodgkin’s lymphoma, specifically cutaneous…
Experts discuss the diagnosis and treatment of myositis-related cardiovascular disease.
Interstitial lung disease accompanied by anti-melanoma differentiation-associated gene 5 positive dermatomyositis is often rapidly progressive and associated with poor prognosis. In this study, a combined immunosuppressive regimen of high-dose glucocorticoids, tacrolimus and intravenous cyclophosphamide proved more effective than treatment with high-dose glucocorticoids and stepwise addition of an immunosuppressant in a historical control group.
During a session at the 2019 ACR/ARP Annual Meeting, Lisa Christopher-Stine, MD, MPH, provided valuable recommendations and practical insights into the care and treatment of myositis patients…
The idiopathic inflammatory myopathies (IIM) encompass eight categories: 1) dermatomyositis (DM) in adults, 2) juvenile dermatomyositis, 3) amyopathic DM, 4) cancer-associated DM, 5) polymyositis, 6) immune-mediated necrotizing myopathy, 7) inclusion body myositis, and 8) overlap myositis.1 These categories help classify the myopathies based on clinical and histologic features. The incidence of IIM is estimated at…
Immune checkpoint inhibitors (ICIs) targeting the cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) or programmed cell death protein 1 (PD-1) axes have revolutionized therapy and improved survival in advanced cancers. However, these immune system modulators also lead to immune-related adverse events (IRAEs).1,2 In clinical trials, IRAEs mainly involved the gastrointestinal tract, skin, endocrine glands, liver and lung,…
A recent study details the autoantibodies of patients with myositis, confirming most patients carry these antibodies. The results also describe how myositis-specific autoantibodies can be used to identify distinct clinical subsets of idiopathic inflammatory myopathy…
New data from India suggest women with idiopathic inflammatory myositis are at increased risk of poor fetal outcomes and spontaneous abortions. In the study, researchers found these women had worse obstetric outcomes and increased risk of fetal complications…
Since it was first reported in 1916, a correlation between inflammatory myopathies and cancer has been noted in several studies. Population studies have confirmed this relationship, and the phrase cancer-associated myopathy has entered the vernacular. Over the past decade, research efforts have shifted toward revealing associations between autoantibodies and clinical phenotypes. One subset of auto-antigens…
Immune checkpoint inhibitors (ICIs) are at the forefront of advances in cancer therapy and have shown promising results for progression-free survival. Checkpoint signaling pathways, such as cytotoxic T-lymphocyte antigen 4 (CTLA-4) and programmed cell death protein 1 (PD-1), normally regulate the immune response to promote self-tolerance and prevent tissue damage and inflammation. PD-1 is a…
