Introduction: Antisynthetase syndrome (ASS) is characterized by the presence of anti-Jo-1 antibodies in conjunction with clinical findings of fever, polymyositis-dermatomyositis, and interstitial lung disease (ILD). Inflammatory myopathies carry a high risk of malignancy, but this association is less well outlined in ASS. We present the case of a patient with ASS who developed non-Hodgkin's lymphoma with acute hypoxemic respiratory failure. Case Presentation: A 44-year-old female with ASS presented with acute hypoxemic respiratory failure...

OBJECTIVE: We aimed to establish the prevalence and clinical associations of anti-HMG-CoA-reductase (anti-HMGCR) in a large UK cohort with juvenile myositis. METHODS: There were 381 patients investigated for anti-HMGCR using ELISA. RESULTS: Anti-HMGCR autoantibodies were detected in 4 patients (1%). These children had no or minimal rash and significant muscle disease. Muscle biopsies were considered distinctive, with widespread variation in fiber size, necrotic fibers, and chronic inflammatory cell infiltrates; all had prolonged elevation of creatine kinase and all ultimately received biologic therapies...

The inflammatory myopathies are a group of immune-mediated inflammatory muscle disorders that typically present with marked proximal muscle weakness. We report four cases of inflammatory myopathies with marked subcutaneous oedema as their main complaint. Three of the four patients had normal or low levels of creatine kinase, an enzyme often markedly elevated in these disorders. Magnetic resonance imaging of the muscles, followed by a muscle biopsy were used to make a definitive diagnosis.

Dermatomyositis is an idiopathic inflammatory myopathy that cause skin and muscle complications. The ethiology is not understood well yet. Released cytokines including interferon and interleukins are suggested to make inflammatory responses in the skin or muscle. Muscle weakness and skin lesions including heliotrope rash, shawl sign and Gottron's papules are the most common symptoms. A biopsy (muscle or skin) is always the most reliable method for diagnosis. Corticosteroids in association with immunosuppressive agents are used as standard treatment...

BACKGROUND: Metabolic alterations play a role in the development of inflammatory myopathies (IMs). Herein, we have investigated through a multiplex assay whether proteins of energy metabolism could provide biomarkers of IMs. METHODS: A cohort of thirty-two muscle biopsies and forty plasma samples comprising polymyositis (PM), dermatomyositis (DM) and sporadic inclusion body myositis (sIBM) and control donors was interrogated with monoclonal antibodies against proteins of energy metabolism using reverse phase protein microarrays (RPPA)...

Skeletal muscle is the most abundant tissue in the human body and can adapt its mass as a consequence of physical activity, metabolism, growth factors, and disease conditions. Skeletal muscle contains an extensive network of endoplasmic reticulum (ER), called sarcoplasmic reticulum, which plays an important role in the regulation of proteostasis and calcium homeostasis. In many cell types, environmental and genetic factors that disrupt ER function cause an accumulation of misfolded and unfolded proteins in the ER lumen that ultimately leads to ER stress...

Juvenile dermatomyositis (JDM) is a chronic inflammatory myopathy and vasculopathy driven by genetic and environmental influences. Here, we investigated the genetic underpinnings of an analogous, spontaneous disease of dogs also termed dermatomyositis (DMS). As in JDM, we observed a significant association with a haplotype of the major histocompatibility complex (MHC) (DLA-DRB1*002:01/-DQA1*009:01/-DQB1*001:01), particularly in homozygosity (P-val = 0.0001). However, the high incidence of the haplotype among healthy dogs indicated that additional genetic risk factors are likely involved in disease progression...

OBJECTIVES: Pneumocystis jiroveci pneumonia (PJP) is an opportunistic infection with high mortality among patients with underlying rheumatologic conditions. Given the paucity of prospective data to guide treatment, clinical guidelines to initiate PJP prophylaxis are based on expert opinion and identify patients on ≥20 mg daily prednisone for ≥4 weeks duration for treatment. Herein we describe the PJP experience in rheumatic disease over a 20-year period at a single academic medical centre to investigate this 20 mg threshold and risk associated with lymphocyte counts, co-existing lung disease and immunosuppressive medications...

Background Juvenile dermatomyositis (JDM), a rare autoimmune disease, accounts for more than 80% of idiopathic inflammatory myopathy childhood cases, making it the most common idiopathic inflammatory myopathy among children. The average age of onset is approximately 7 years and commonly leads a chronic course. Symptoms of JDM include cutaneous features (Gottron's rash, heliotrope rash, or nail fold capillary changes), musculoskeletal features, calcinosis and lipodystrophy (a symmetrical deficit of subcutaneous fatty tissue), and acanthosis (thickening of the skin)...

BACKGROUND: Patients with non-scleroderma connective tissue-related lung disease (NS-CTLD), including rheumatoid arthritis, idiopathic inflammatory myopathies, Sjögren syndrome, mixed connective tissue disease, and systemic lupus erythematosus, may be at risk for worse outcomes after lung transplantation because of immune dysregulation or extrapulmonary manifestations of their underlying disease. We compared survival, acute and chronic rejection, and extrapulmonary organ dysfunction after transplantation in patients with NS-CTLD and idiopathic pulmonary fibrosis (IPF)...

In horses, immune-mediated muscle disorders can arise from an overzealous immune response to concurrent infections or potentially from an inherent immune response to host muscle antigens. Streptococcus equi ss. equi infection or vaccination can result in infarctive purpura hemorrhagica (IPH) in which vascular deposition of IgA-streptococcal M protein complexes produces ischemia and complete focal infarction of skeletal muscle and internal organs. In Quarter Horse-related breeds with immune-mediated myositis, an apparent abnormal immune response to muscle antigens results in upregulation of major histocompatibility complex class (MHC) I and II on muscle cell membranes, lymphocytic infiltration of lumbar and gluteal myofibers, and subsequent gross muscle atrophy...

OBJECTIVE: Extensive studies on health-related quality of life (HRQOL) in idiopathic inflammatory myopathies (IIM) are lacking. Our objective was to document HRQOL and to identify factors associated with a reduced HRQOL in IIM patients. METHODS: A total of 1,715 patients (median age 49.9, 70% female, 87% Caucasian) who met probable or definite Bohan and Peter or Griggs criteria for myositis were included from the MYOVISION registry. HRQOL was ascertained via the SF-12v2® Health Survey questionnaire...

Sporadic inclusion body myositis (sIBM) is an insidious late onset progressive myopathy that typically affects patients over the age of 50. Clinically, patients develop a characteristic pattern of weakness that affects the forearm flexors and knee extensors. Muscle biopsy, often utilized in the diagnosis, demonstrates a chronic myopathy with mixed pathologies harboring intramyofiber protein inclusions and endomysial inflammation. The co-existence of these pathologic features (i.e. inflammation and protein aggregation) has divided the field of sIBM research into two opposing (albeit slowly unifying) camps regarding disease pathogenesis...

Aicardi-Goutières syndrome (AGS) is an inflammatory disorder belonging to the recently characterized group of type I interferonopathies. The most consistently affected tissues in AGS are the central nervous system and skin, but various organ systems and tissues have been reported to be affected, pointing to the systemic nature of the disease. Here we describe a patient with AGS due to a homozygous p.Arg114His mutation in the TREX1 gene. The histologically proven inflammatory myopathy in our patient expands the range of clinical features of AGS...

Jessica Day, Sandy Patel, Vidya Limaye
Magnetic resonance imaging (MRI) is an important tool in the evaluation of neuromuscular disorders. MRI accurately demonstrates muscle oedema, atrophy, subcutaneous pathology and fatty infiltration and also highlights the distribution of muscle involvement. This review examines the role of MRI in evaluation of the idiopathic inflammatory myopathies (IIMs), a heterogeneous group of autoimmune conditions characterised by muscle inflammation and a variety of extra-muscular manifestations. MRI has a clear role in aiding diagnosis of these conditions, guiding muscle biopsy, differentiating subtypes of IIM using a pattern-based approach, and monitoring disease activity in a longitudinal fashion...
