Single-nucleotide polymorphisms (SNPs) in the ETS1 gene are associated with several auto-inflammatory diseases. In this study, we determined whether ETS1 gene polymorphisms confer susceptibility to idiopathic inflammatory myopathies (IIMs) in a northern Chinese Han population. DNA samples were collected from 1017 IIM patients: 363 PM cases and 654 DM cases. The results were compared with those of 1280 healthy controls. Five SNPs in the ETS1 region (rs7117932, rs6590330, rs4937362, rs10893845 and rs1128334) were assessed and genotyped using the Sequenom platform...

PURPOSE OF REVIEW: The study aimed to illustrate the cardiopulmonary findings of the following collagen vascular diseases on cross-sectional imaging: rheumatoid arthritis, scleroderma (progressive systemic sclerosis), systemic lupus erythematosus, the inflammatory myopathies (polymyositis/dermatomyositis), and Sjögren's syndrome. RECENT FINDINGS: Although collagen vascular diseases can affect any part of the body, interstitial lung disease and pulmonary hypertension are the two most important cardiopulmonary complications and are responsible for the majority of morbidity and mortality in this patient population...

BACKGROUND: Patients with suspected idiopathic inflammatory myopathies (IIM) are commonly tested for the presence of anti-nuclear antibodies (ANA) by indirect immunofluorescence (IIF) on HEp-2 cell substrates. However, ANA-IIF false negative tests may occur in IIM because some antigens, such as Jo1 and Ro52, may be scarcely expressed on HEp-2 cells. In addition, cytoplasmic staining is often not appropriately investigated by a specific antibody assay, leading to decreased clinical sensitivity of the ANA test...

CONTEXT: - Patients with anti-aminoacyl-tRNA synthetase syndrome (ARS), a subset of idiopathic inflammatory myopathy, have a high prevalence of lung involvement. Autoantibodies directed against alanyl-tRNA synthetase (anti-PL-12 Abs) represent 1 of the 8 autoantibodies currently described under the rubric of ARS. OBJECTIVE: - To describe the clinical, radiographic, and pulmonary histopathologic findings in patients possessing anti-PL-12 autoantibodies. DESIGN: - Patients with anti-PL-12 ARS were identified in the University of Pittsburgh Idiopathic Inflammatory Myopathy registry...

Focal myositis are inflammatory muscle diseases of unknown origin. At the opposite from the other idiopathic inflammatory myopathies, they are restricted to a single muscle or to a muscle group. They are not associated with extramuscular manifestations, and they have a good prognosis without any treatment. They are characterized by a localized swelling affecting mostly lower limbs. The pseudo-tumor can be painful, but is not associated with a muscle weakness. Creatine kinase level is normal. Muscle MRI shows an inflammation restricted to a muscle or a muscle group...

Dermatomyositis (DM) is an idiopathic inflammatory myopathy characterized by an inflammatory infiltrate primarily affecting the skeletal muscle and skin [1]. It is the commonest of the idiopathic inflammatory myopathies of childhood, comprising 85% of cases. It has an annual incidence estimated to range between 1.9 and 4.1 per million children [2, 3].

The present study was undertaken to assess mortality, causes of death, and associated prognostic factors in a large cohort of patients diagnosed with idiopathic inflammatory myositis (IIM) from Spain. A retrospective longitudinal study was carried out in 467 consecutive patients with IIM, identified from 12 medical centers. Patients were classified as primary polymyositis, primary dermatomyositis (DM), overlap myositis, cancer-associated myositis (CAM), and juvenile idiopathic inflammatory myopathies. A total of 113 deaths occurred (24%) after a median follow-up time of 9...

OBJECTIVES: To investigate the association between infection or respiratory tract disease and future risk of developing idiopathic inflammatory myopathy (IIM). METHODS: A case-control study was performed using Swedish nationwide registers. Adults with newly diagnosed IIM were identified (2002-2011) from the National Patient Register (NPR) and the Swedish Rheumatology Register (n=957). Controls were matched by age, sex and place of residence (n=9476). Outpatient visits and hospitalisations preceding IIM diagnosis indicating infection or respiratory disease were identified from NPR...

AIMS: The EuroMyositis Registry facilitates collaboration across the idiopathic inflammatory myopathy (IIM) research community. This inaugural report examines pooled Registry data. METHODS: Cross-sectional analysis of IIM cases from 11 countries was performed. Associations between clinical subtypes, extramuscular involvement, environmental exposures and medications were investigated. RESULTS: Of 3067 IIM cases, 69% were female. The most common IIM subtype was dermatomyositis (DM) (31%)...

PURPOSE OF REVIEW: The purpose of this review is to provide an update on cardiovascular involvement in idiopathic inflammatory myopathy (IIM). Studies from the past 18 months are identified and reviewed. Finally, the clinical impact of these findings is discussed. RECENT FINDINGS: Epidemiological studies have revealed an increased risk of myocardial infraction and venous thromboembolism (VTE) - including deep venous thrombosis and pulmonary embolism - in adults with polymyositis or dermatomyositis compared to the general population, even after adjustment for potential confounders...

This study aimed to investigate the multiple values of (18)F-FDG PET/CT in detecting malignant tumors, evaluating myopathy, and determining interstitial lung disease in patients with idiopathic inflammatory myopathy (IIM). We retrospectively analyzed the data of 38 patients who were examined by (18)F-FDG PET/CT and eventually diagnosed as IIM. We also collected the data of another 22 cases with negative PET/CT as the control. Pulmonary HRCT images were acquired simultaneously with regular (18)F-FDG PET/CT imaging for each patient...

PURPOSE OF REVIEW: As treatment of refractory cases of idiopathic inflammatory myopathies (IIMs) has been challenging, there is growing interest in assessing novel biologics that target various pathways implicated in the pathogenesis of IIM. RECENT FINDINGS: In the largest clinical trial in adult and juvenile IIM assessing the effectiveness of rituximab, the primary outcome was not met but 83% of this refractory group of IIM patients met a predefined definition of improvement and rituximab demonstrated a significant glucocorticoid-sparing effect...

REVIEW
K E N Clark, D A Isenberg
Inflammatory idiopathic myopathies are a group of autoimmune diseases affecting predominantly the proximal skeletal muscles, with raised muscle enzymes, with or without skin involvement and extramuscular organ involvement. Autoantibodies help to characterize patients into different clinical phenotypes. Successful treatment necessitates controlling inflammation early with corticosteroids and invariably requires additional immunosuppressive therapy. This review focuses on the aetiology, pathogenesis, clinical presentation, investigations and management of patients presenting with inflammatory idiopathic myopathies, predominantly focusing on polymyositis and antisynthetase syndrome...

Patients with idiopathic inflammatory myopathies (IIMs) suffer an increased burden of comorbidities, but data on mortality in recently diagnosed IIM are conflicting. Also, little is known when, if ever, in relation to IIM diagnosis, mortality is increased. METHODS: A population-based IIM cohort of patients diagnosed between 2002 and 2011 and general population comparators were identified using healthcare registers. They were linked to the cause of death register for follow-up. RESULTS: 224 (31%) of the 716 patients with IIM and 870 (12%) of the 7100 general population died during follow-up...

Dermatomyositis (DM) is an idiopathic inflammatory myopathy characterized by CD4+ T cells and B cells infiltration in perivascular and muscle tissue. Although the infiltration of inflammatory cells plays a key role in muscle damage, the exact mechanism is not clear. Cathepsin G (CTSG) is a member of the serine proteases family and can increase the permeability of vascular endothelial cells and the chemotaxis of inflammatory cells. In this study, we found that the expression of CTSG was increased in peripheral blood mononuclear cells and muscle tissues of DM patients...

PURPOSE OF REVIEW: MRI is a promising imaging method commonly used to assess muscle involvement in patients with idiopathic inflammatory myopathies (IIM). MRI enables evaluation of both activity and damage and is therefore an ideal noninvasive diagnostic and monitoring tool. Despite its widespread use, there is no universally accepted method for scoring and reporting of MRI findings. The aim of this review is to provide an overview of systems used in the evaluation of MR images in patients with IIM...
