Idiopathic inflammatory myopathies (IIMs) are a group of autoimmune muscle diseases with significant morbidity and mortality. This review details and updates the pathogenesis and emerging importance of myositis-specific antibodies in the development of IIMs. An increase in the understanding of how these myositis-specific antibodies play a role in IIMs has led to the further categorization of IIMs from the traditional polymyositis versus dermatomyositis, to additional subcategories of IIMs such as necrotizing autoimmune myositis (NAM)...

We report the case of a 32-year-old woman with severely elevated serum creatine kinase (CK; 80,000 U/l) and progressive proximal pareses. As muscular biopsy showed inflammatory infiltrates, polymyositis was suspected and immunosuppressive treatment was initiated. However, clinical improvement could not be achieved. Gene sequencing of the DYSF-gene showed a previously unreported homozygous mutation. In summary, elevated serum CK and inflammatory infiltrates in the muscle biopsy are not specific for polymyositis, but may also occur in degenerative diseases (muscular dystrophy), such as dysferlinopathy...

Patients with Rheumatic diseases (RDs) are at an increased risk of malignancies compared with the general population. The aim of this study was to examine the relative frequency of several cancers in a single homogeneous cohort of patients with different RDs. Patients diagnosed with rheumatoid arthritis (RA), Ankylosing spondylitis (AS), Sjögren's syndrome (SS), systemic lupus erythematosus (SLE), systemic sclerosis (SSc), dermatomyositis (DM), or polymyositis were included. Out of 3982 adult residents admitted to the division of rheumatology, 61 malignancies were observed...

BACKGROUND: Chronic graft-versus-host disease (GVHD) appears several months following allogenic hematopoietic stem cell transplantation (HSCT) and is clinically analogous to autoimmune disorder. Polymyositis is a common neuromuscular disorder in chronic GVHD, but myasthenia gravis (MG) is extremely rare. Hence, its pathophysiology and treatment have not been elucidated. CASE PRESENTATION: A 63-year-old man with a history of chronic GVHD presented with ptosis, dropped head, and dyspnea on exertion, which had worsened over the previous several months...

This study aimed at analyzing published data on the association between idiopathic inflammatory myopathy and venous thromboembolism (VTE). We examined studies on VTE risk in patients with polymyositis (PM) and/or dermatomyositis (DM), in the MEDLINE, EMBASE, and Cochrane databases and via manual searches. We performed a meta-analysis on the relative risks (RRs) of VTE, pulmonary embolism (PE), and deep vein thrombosis (DVT) in these patients. Five studies, including 8858 patients with PM/DM met the inclusion criteria...

Immune-mediated myopathies (IMMs) are a heterogeneous group of acquired muscle disorders characterized by muscle weakness, elevated creatine kinase levels, and myopathic electromyographic findings. Most IMMs feature the presence of inflammatory infiltrates in muscle. However, the inflammatory exudate may be absent. Indeed, necrotizing autoimmune myopathy (NAM), also called immune-mediated necrotizing myopathy, is characterized by a necrotizing pathologic process with no or minimal inflammation in muscle. The recent discovery of antibodies associated with specific subtypes of autoimmune myopathies has played a major role in characterizing these diseases...

Single nucleotide polymorphisms (SNPs) in TNFSF4 and ANKRD55 genes have been shown to be associated with several autoimmune diseases, although whether these genes are susceptibility genes for dermatomyositis/polymyositis (DM/PM) has, to date, not been reported. This study aimed to investigate the potential associations of these SNPs with DM/PM in a Chinese Han population. Five SNPs in TNFSF4 (rs2205960, rs844644, and rs844648) and ANKRD55 (rs6859219, rs7731626) genes were genotyped using the SequenomMassArray system in 2297 Chinese individuals...

Antisynthetase syndrome (ASS) is a rare chronic autoimmune disorder (2-3 times more common in women than in men), associated with interstitial lung disease (the most important feature), dermatomyositis (DM), and polymyositis (PM). The cause of ASS is unknown. Recent developments in immunology have improved our knowledge and it is now possible to classify ASS according to the presence of myositis specific autoantibodies. The hallmark of ASS is the presence of serum autoantibodies directed against aminoacyl-tRNA synthetases (anti-ARS involved in protein synthesis)...

RATIONALE: Anti-aminoacyl transfer RNA synthetase antibodies (anti-ARS) are a group of myositis-specific autoantibodies that are detected in the sera of patients with polymyositis and dermatomyositis (PM/DM) and also in those of patients with idiopathic interstitial pneumonias without any connective tissue disease (CTD), including PM/DM. Although we reported the clinical characteristics of interstitial lung disease with anti-ARS antibodies (ARS-ILD) with and without PM/DM, the long-term prognosis of ARS-ILD remains undetermined...

The presence of anti-MDA5 antibodies in serum represents an important biomarker in the diagnosis and prediction of prognosis for patients with idiopathic inflammatory myopathies (IIMs). Due to conflicting results that have been reported regarding the detection of anti-MDA5 antibodies, the goal of this study was to assess a potential association between the presence of anti-MDA5 antibodies and dermatomyositis/polymyositis (DM/PM), as well as the diagnostic and prognostic values of anti-MDA5 antibodies for DM/PM...

We report a 62-year-old woman with a history of Basedow's disease and Sjogren's syndrome who presented with slowly progressive limb muscle weakness over the course of ten years. On physical examination, she had dry eye and mouth, but was otherwise normal. Neurological examination revealed symmetrical proximal dominant muscle weakness. Polymyositis was suspected at initial diagnosis due to her clinical course, physical examination, and autoimmune disease. However, the final diagnosis based on a muscle biopsy was the chronic myopathic type of sarcoid myopathy...

OBJECTIVE: Toll-like receptor 4 (TLR4) is one of the key players in the development of many autoimmune diseases. To determine the possible role of TLR4 in polymyositis (PM) development, we collected muscle samples from PM patients and mice subjected to an experimental autoimmune myositis (EAM) model. METHODS: We measured TLR4-MyD88 pathway-related factors, interferon-γ (IFN-γ), and interleukin-17A (IL-17A) in EAM mice and PM patients. Then, we observed the changes of above factors and the inflammatory development of EAM mice with TLR4 antagonist TAK-242, IFN-γ, or IL-17A antibody treatment...

BACKGROUND Idiopathic inflammatory myopathies are autoimmune disorders that can involve the skin, joints, muscles, and lungs. The most common of these disorders are dermatomyositis, polymyositis, overlap syndrome, and inclusion body myositis. Necrotizing autoimmune myopathy is an idiopathic inflammatory myopathy that is rarely associated with Sjögren's syndrome. The most common lung findings associated with anti-EJ antisynthetase syndrome are nonspecific interstitial pneumonia and usual interstitial pneumonia; this condition is rarely associated with fibrinous and organizing pneumonia...

INTRODUCTION: The association of myasthenia gravis (MG) and inflammatory myopathy is rare and often only one of the diseases is diagnosed. Thymus pathology may be in the origin of such disease association. METHODS: We described four patients with both MG and inflammatory myopathy. RESULTS: These cases correspond to 2.3% of our MG cohort. Case 1: MG, polymyositis and thymolipoma; case 2: MG and necrotizing myopathy without thymic pathology on a background of scleroderma, Raynaud's phenomenon, esophageal dysmotility, sclerodactyly, telangiectasia (CREST); case 3: MG and dermatomyositis without thymic pathology; case 4: MG and dermatomyositis with type C thymoma...

A 72-year-old woman was admitted to our hospital and was diagnosed with interstitial pneumonia (IP) associated with amyopathic dermatomyositis (ADM). The patient experienced three acute IP exacerbations in the 7 years that followed, which were each treated and resolved with steroid pulse therapy. The patient was closely examined for respiratory failure with right heart catheterization (RHC), which demonstrated that she had a mean pulmonary artery pressure (mPAP) of 34 mmHg. The patient was thus diagnosed as having pulmonary hypertension (PH) associated with anti-synthetase syndrome (ASS) and was started on bosentan therapy, which led to improvements in mPAP as well as in subjective symptoms over time...
