Immunotherapies in autoimmune inflammatory myopathies: Rationale and therapeutic updates.

Handbook of clinical neurology2026

Autoimmune inflammatory myopathies (AIM) constitute a heterogeneous group of acquired myopathies with endomysial inflammation as a shared feature highlighting a potentially autoimmune inflammatory process amenable to immunotherapies. The disorders can be best classified as dermatomyositis, necrotizing autoimmune myositis, antisynthetase syndrome-overlap myositis, and inclusion body myositis. Because of clinical and immunohistologic heterogeneity but often overlapping pathophysiologic features among all major subsets, a correct diagnosis is critical from the outset to apply the most suitable and subset-specific immunotherapy. Advances in the immunopathologic characterization of autoimmune inflammatory myopathies have identified potentially mechanism-specific disease subsets that promise the application of targeted immunotherapies for better clinical outcomes. A number of recent clinical trials with biologic agents and monoclonal antibodies, regardless of the clinical outcome considering that several were negative, have collectively expanded our knowledge on the main pathogenic markers of autoimmunity associated with each AIM subset including the role of T-cell or B-cell factors, key cytokines, complement and various associated antibodies, or innate immunity factors. The paper summarizes the main clinical and histopathologic features of each myositis subtype, including overlapping or unique concepts of their immunopathogenic mechanisms, being mainly focused on applied immunotherapies and relevant controlled clinical trials discussing evidence-based efficacy according to the currently evolved therapeutic algorithm. The ongoing trials are also discussed highlighting those with promising future, if applied early in the disease, and the new immunotherapeutic interventions for the refractory AIM subsets.

Prevalence and Risk of Falls and Fractures in the Idiopathic Inflammatory Myopathies: A Cross-Sectional Study of 470 Patients.

Rheumatology and therapy2026 Mar 21

Patients with idiopathic inflammatory myopathies (IIMs) can develop marked muscle weakness, which predisposes them to falls and injuries. We examined the prevalence of falls and associated fractures, assistive device use, and bone-protective therapy use among those reporting a fracture history. This analysis focuses on secondary prevention strategies in a high-risk population. A cross-sectional survey was developed and distributed by Myositis Support and Understanding, a patient-led advocacy organization, to members of its group. Patients aged ≥ 18 years with a diagnosis of an IIM (dermatomyositis, antisynthetase syndrome, polymyositis, inclusion body myositis [IBM], immune-mediated necrotizing myopathy, or overlap myositis [OM]) were eligible to participate. Ordinal logistic regression was utilized to identify variables independently associated with falls. Of 470 respondents, 79.8% reported falling once since diagnosis, and 57.0% fell within the past year. Fall-related fractures since diagnosis were reported by 121 participants (25.7%), of whom 61 (50.4%) experienced ≥ 2 fractures and 39 (32.2%) required surgical treatment. Among those with fall-related fractures, nearly half (47.9%) reported not receiving any dietary supplements or pharmacologic therapies (e.g., calcium, vitamin D, or bisphosphonates) to reduce bone loss or prevent future fractures. Use of braces/splints or mobility aids was reported by 18.2% and 77.7% of participants with fall-related fractures, respectively. Regression analyses identified mobility aid usage as being associated with a significantly increased fall risk (odds ratio [OR], 3.1; P < 0.001). Relative to dermatomyositis, fall risk was significantly higher among participants with IBM (OR, 2.5; P = 0.002) and polymyositis (OR, 2.0; P = 0.037) and lower for participants with antisynthetase syndrome (OR, 0.5; P = 0.038). All IIMs can lead to marked weakness, with varying individual risks of falls. Multidisciplinary care, with an emphasis on primary and secondary prevention of falls and fractures, is critical to improving outcomes and preserving quality of life in these patient populations. People with idiopathic inflammatory myopathies, a group of diseases that cause muscle inflammation and weakness, often experience significant challenges that can affect their daily activities and make them more prone to falls and injuries. A survey conducted by Myositis Support and Understanding asked its members with idiopathic inflammatory myopathies about their experience with falls, bone fractures, and treatments for their condition. The results showed that 79.8% of the 470 survey respondents had fallen at least once since their diagnosis and 57.0% had fallen in the past year. Among the 25.7% of people who experienced fall-related fractures, half of them had multiple fractures, and nearly one-third needed surgery. Nearly half of the people who had fractures from falls said they were not taking any vitamins, supplements, or medications—like calcium, vitamin D, or bone-strengthening drugs—to help protect their bones or prevent more fractures. To help with mobility, 18.2% of people used braces or splints, and 77.7% used mobility aids such as walkers or canes. People with inclusion body myositis and people with polymyositis had a higher risk of falling compared with those with dermatomyositis. Although all types of idiopathic inflammatory myopathies can cause serious muscle weakness, some may increase the risk of falls more than others. Preventing falls and fractures is critical for improving the quality of life of people with idiopathic inflammatory myopathies.

Clinical profiles associated with rapidly progressive interstitial lung disease in antisynthetase syndrome: A multicentric cohort study (TYPASS study).

Journal of internal medicine2026 Mar

To assess factors associated with rapidly progressive interstitial lung disease (ILD) (RP-ILD) at time of ILD diagnosis in a multicentric retrospective cohort study of antisynthetase syndrome (ASyS). We used a complementary unsupervised approach, hierarchical clustering, to delineate distinct phenotypes among ASyS patients with ILD. A total of 132 patients with ASyS, defined according to the 2024 ACR/European Alliance of Associations for Rheumatology (EULAR) ASyS classification criteria, and ILD, diagnosed by CT scan, were included. RP-ILD was defined by the presence of respiratory failure at ILD diagnosis or rapid ILD progression during the first 3 months. In our study, 39% of patients had RP-ILD at ILD diagnosis. Multivariate logistic regression analysis with cluster-robust SE identified the factors associated with RP-ILD at ILD diagnosis as male sex (aOR = 9.7 [1.6-59.5], p = 0.006), fever (aOR = 128 [12.6-1300], p < 0.001), organizing pneumonia (OP) pattern (aOR = 66.8 [3.4-1316], p = 0.006), and pleural effusion (aOR = 20.2 [1.1-373], p = 0.04), whereas RP-ILD was associated with lower likelihood of severe muscle disease (aOR = 0.004 [0.0001-0.13], p = 0.002). Clustering analysis identified four distinct groups: Cluster 1 (n = 62) included patients with systemic presentation, non-RP-ILD at ILD diagnosis, and anti-Jo-1 antibodies with good prognosis; Cluster 2 (n = 40) included older age patients with more RP-ILD at ILD diagnosis, pleuropericarditis, and a higher mortality rate. Fever, pleural effusion, and OP pattern were independently associated with RP-ILD in ASyS patients. Unsupervised cluster analysis identified a severe inflammatory phenotype in ASyS patients with ILD.

Factors associated with interstitial lung disease among patients with idiopathic inflammatory myopathies.

Rheumatology (Oxford, England)2026 Mar 05

Idiopathic inflammatory myopathies (IIM) are heterogeneous disorders that often affect the lungs as IIM-associated interstitial lung disease (IIM-ILD). We used Meta-ANalysis of Transethnic Associations (MANTRA) and machine learning methods to evaluate predictors of IIM-ILD. Subjects (N = 450) were enrolled in studies at the National Institutes of Health. We studied adult (N = 262) and juvenile (N = 188) DM (N = 276), PM (N = 109) and overlap myositis (N = 61) patients with clinical, autoantibody, HLA, and single nucleotide polymorphism (SNP) data, with (N = 162) or without (N = 288) ILD. Logistic regression and MANTRA analyses were used to evaluate the associations of SNPs (Muc5b rs35705950, TOLLIP rs5743890 and rs3750920, TLR5 rs5744168, and TERT rs2736100) previously identified as risks for idiopathic pulmonary fibrosis (IPF). Classification and regression tree (CART) and gradient boosting machine learning were used to simultaneously evaluate the clinical, autoantibody, HLA and SNP data for their relative predictive power of ILD. Smoking status, older age, African American heritage and certain HLA genes were associated with IIM-ILD, but anti-synthetase, myositis-associated and anti-MDA5 autoantibodies showed the strongest risk associations, with an increased odds of ILD by up to 20-fold. Conversely, anti-signal recognition particle, anti-TIF1 (P155/140) and anti-NXP2 autoantibodies showed the strongest protective effects, with decreased odds of ILD by up to 40%. The effects of some HLA allele groups and IPF SNPs on ILD were inconsistent and weaker. This sample of IIM patients showed autoantibodies to be the strongest predictive or protective factors for ILD, yet the full range of associations of IIM-ILD remain undefined.

Autoantibody internalization in myositis skeletal muscle: Emerging evidence, mechanistic insights, and therapeutic relevance.

Autoimmunity reviews2026 Feb

The inflammatory myopathies-including dermatomyositis, immune-mediated necrotizing myopathy, anti-synthetase syndrome, and overlap myositis-are systemic autoimmune diseases characterized by myositis-specific and myositis-associated autoantibodies targeting intracellular antigens. These diseases can be subclassified by autoantibody seropositivity, based on the understanding that each myositis autoantibody is associated with distinct clinical features. Traditionally, given the intracellular nature of their targets, myositis autoantibodies were thought to be non-pathogenic. However, this idea is now being challenged based on data from recent and older studies showing that autoantibodies reach their intracellular targets in vivo and exert functional pathogenic effects. In this review, we summarize experimental evidence supporting a model of pathogenic autoantibody internalization in the skeletal muscle of different inflammatory myopathies. We also address gaps in the evidence for this model, including the lack of a proven mechanism of autoantibody entry, while offering suggestions for future studies to fill these gaps. We discuss possible mechanisms of autoantibody entry, as well as the diagnostic, prognostic, and therapeutic implications of this model. Finally, we propose that autoantibodies targeting intracellular antigens in other autoimmune diseases-including certain autoimmune neurologic disorders, systemic sclerosis, systemic lupus erythematosus, and vasculitis-could potentially play a role in these conditions.
