Article Abstract

Idiopathic inflammatory myopathies (IIM), also referred to as "myositis," are a group of heterogeneous autoimmune disorders characterised by muscle weakness, atrophy and progressive reduced mobility (Lundberg et al, 2021). IIM represent a significant health burden in adult populations, affecting individuals at a mean age of 50 with an estimated prevalence of 2.9-34 per 100,000 (Dobloug et al, 2015; Svensson et al, 2017). IIM encompass several subtypes including dermatomyositis, immune-mediated necrotising myopathy, inclusion-body myositis, antisynthetase syndrome and polymyositis, which are characterised by specific clinical features, histopathological findings and autoantibody status (Pinal-Fernandez et al, 2020).

A Scoping Review of Respiratory Dysfunction in Inclusion Body Myositis.

Int J Rheum Dis

September 2025

Department of Communication Science and Disorders, School of Health and Rehabilitation Sciences, University of Pittsburgh, Pittsburgh, Pennsylvania, USA.

Objectives: Inclusion body myositis (IBM) can result in deadly respiratory consequences. Yet, the mechanism driving this issue remains equivocal. We mapped the literature to identify physiological respiratory characteristics in IBM and the types of respiratory assessments used.

ERS/EULAR clinical practice guidelines for connective tissue diseases associated interstitial lung disease.

Ann Rheum Dis

September 2025

Department of Rheumatology, University Hospital Zurich, University of Zurich, Zurich, Switzerland; Department of Rheumatology, Oslo University Hospital, Oslo, Norway. Electronic address:

Background: Interstitial lung disease (ILD) is a frequent manifestation of connective tissue diseases (CTDs) and is associated with high morbidity and mortality. Clinical practice guidelines to standardise screening, diagnosis, treatment and follow-up for CTD-ILD are of high importance for optimised patient care.

Methods: A European Respiratory Society and European Alliance of Associations for Rheumatology task force committee, composed of pulmonologists, rheumatologists, pathologists, radiologists, methodologists and patient representatives, developed recommendations based on PICO (Patients, Intervention, Comparison, Outcomes) questions with grading of the evidence according to the GRADE (Grading of Recommendations, Assessment, Development and Evaluations) methodology and complementary narrative questions agreed on by both societies.

Objectives: This study aimed to establish a risk prediction model for the relapse of anti-synthetase syndrome-associated interstitial lung disease (ASyS-ILD).

Methods: Patients diagnosed with ASyS-ILD and treated with prednisolone and calcineurin inhibitors as remission induction therapy were enrolled in the Japanese multicentre MYKO cohort. We followed up on patients who experienced relapse of ASyS-ILD after remission induction therapy, and examined the risk factors for predicting relapse by comparing initial clinical and laboratory findings.

Cofactors are external factors that can lower the threshold dose of an allergen and amplify the severity of allergic reactions, turning mild or moderate responses into severe anaphylaxis. These include exercise, nonsteroidal anti-inflammatory drugs (NSAIDs), alcohol, menstruation, and infections. Initially described in relation to food allergens and physical activity or NSAIDs, these reactions have been labeled under various terms, such as food-dependent exercise-induced anaphylaxis (FDEIA), wheat-dependent exercise-induced anaphylaxis (WDEIA), and food-dependent NSAID-induced anaphylaxis (FDNIA).

Vitamin D Status in Paraguayan Children With Autoimmune Diseases.

Int J Rheum Dis

September 2025

Department of Pediatrics, Facultad de Medicina, Universidad Nacional de Asunción, Asunción, Paraguay.

Introduction: Vitamin D plays a crucial role in modulating the immune system. Numerous studies have elucidated the association between low serum levels of vitamin D and autoimmune diseases. Vitamin D deficiency has been implicated in systemic lupus erythematosus, rheumatoid arthritis (RA), Hashimoto's thyroiditis, juvenile dermatomyositis, inflammatory bowel disease, among others.
