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.
The Care & Treatment of Myositis: Creatinine Kinase Level Isn’t Gospel & Other Recommendations
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…
Myositis-Specific Antibodies Identified
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…
Case Report: Tumor Treatment Unleashes Autoimmunity
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,…
Myositis Autoantibodies as Biomarkers
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…
Pregnancy Outcomes in Women with Idiopathic Inflammatory Myositis
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…
Cancer-Associated Myositis: A Case Report & Review of the Literature
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 & Immune-Related Adverse Events
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…
Promising Avenues in Myositis: Research Targets Disease Specificity
AMSTERDAM—Research in myositis treatments is beginning to find its way, with investigators pursuing avenues special to the disease so therapy for patients may no longer involve piggybacking on existing treatments for other illnesses, an expert said at EULAR: the Annual European Congress of Rheumatology. “Finally, in myositis there are targets being investigated that are more…
Statins Linked to Idiopathic Inflammatory Myositis
NEW YORK (Reuters Health)—Statin use is associated with an increased likelihood of developing idiopathic inflammatory myositis (IIM), researchers from Australia report. “[Although] the incidence of IIM is rare, with the increasing use of statins worldwide and the severity of this condition, this study highlights the need for increased awareness of the condition and the importance…
