BACKGROUND: Macrophage activation is involved in the pathogenesis of polymyositis (PM)/dermatomyositis (DM). CD163, a scavenger receptor expressed on the surface of activated macrophages, mediates anti-inflammatory functions. This study aimed to evaluate the clinical significance of soluble CD163 (sCD163) in PM/DM-related interstitial lung disease (ILD). METHODS: The main subjects were 48 patients with PM/DM-related ILD. As controls, 10 patients with PM/DM without ILD and 20 healthy volunteers were enrolled...

Primary aldosteronism (PA) is a rare disorder. The majority of patients with PA present with typical features and are easily diagnosed. This disorder is usually diagnosed with hypokalemia, hypertension or an adrenal mass. However, patients with atypical symptoms may present a challenge for diagnosis and treatment. In the present study, a case of PA is described that presented with hypokalemic myopathy simulating polymyositis. The patient was a 44-year-old woman who presented with weakness and difficulty walking...

In South Australia, between 2000 and 2014, 57 patients with idiopathic inflammatory myositis (IIM) were treated with intravenous immunoglobulin (IVIg). We reviewed disease characteristics to determine predictors of response to therapy and IVIg dosing and duration to identify opportunities to rationalise IVIg use. Patients with dermatomyositis/polymyositis had a response rate of 77% and were more likely than inclusion body myositis to respond to therapy. Consideration should be given to the use of the lowest possible dose of IVIg and to the undertaking of trials of cessation of IVIg in patients with stable IIM...

BACKGROUND Miyoshi myopathy (MM) is an autosomal-recessive muscle disorder caused by mutations in the DYSF gene. Clinical features and histopathological changes in dysferlinopathies may mimic inflammatory myopathies and a high degree of clinical suspicion is required to guide the genetic investigation. CASE REPORT We report the case of a 16-year-old male who presented with severe bilateral calf pain and elevated CK levels (15 000 IU/l) who was on prolonged steroid therapy prompted by the clinical suspicion of inflammatory myopathy...

DNase1l3 is an endonuclease to degrade the chromatin of apoptotic or necrotic cells. Serum DNase1l3 may fulfill the function of clearance of chromatin released into the circulation by dying cells, which can trigger autoimmune responses. To date, it remains unclear whether serum DNase1l3 level associates with the pathogenesis of autoimmune diseases. Sixty-eight patients with dermatomyositis/polymyositis (DM/PM, n = 30), systemic lupus erythematosus (SLE, n = 20) and rheumatoid arthritis (RA, n = 18), as well as 26 healthy blood donors were enrolled in the present study...

Soo-Jin Park, Dong-Soon Im
Initial discovery on sphingosine 1-phosphate (S1P) as an intracellular second messenger was faced unexpectedly with roles of S1P as a first messenger, which subsequently resulted in cloning of its G protein-coupled receptors, S1P₁₋₅. The molecular identification of S1P receptors opened up a new avenue for pathophysiological research on this lipid mediator. Cellular and molecular in vitro studies and in vivo studies on gene deficient mice have elucidated cellular signaling pathways and the pathophysiological meanings of S1P receptors...

The type I interferon (IFN) system has recently been suggested to play important and essential roles in the pathogenesis of myositis. However, a clarification of how type I IFNs could function as triggering factor(s) in the pathogenesis of myositis has yet failed. Through activation of the type I IFN system, the host defense peptide LL-37 carries numerous immunomodulatory properties and is implicated in the pathogenesis of several other autoimmune diseases, including systemic lupus erythematosus (SLE). The expression of LL-37 can be regulated by various endogenous factors including the active form of vitamin D (25(OH)D3)...

BACKGROUND: We attempted to clarify whether the presence of anti-aminoacyl-transfer RNA synthetase antibody (anti-ARS Ab) or anti-melanoma differentiation-associated gene 5 antibody (anti-MDA5 Ab) is associated with the therapeutic response of polymyositis/dermatomyositis-associated interstitial lung disease (PM/DM-ILD). METHODS: We retrospectively investigated 22 patients with PM/DM-ILD (10 positive for anti-ARS Ab and nine positive for anti-MDA5 Ab) for whom antibody analysis of conserved serum was possible...

OBJECTIVES: Dermatomyositis (DM) and polymyositis (PM) commonly cause weakness of the thigh muscles. However, it is debated whether DM and PM affect similar thigh muscles. Muscle oedema on fat-suppressed MRI sequences is thought to represent active inflammation. In this study, we aimed to assess which thigh muscle groups are preferentially inflamed in DM and PM, respectively, using short-tau inversion-recovery MRI sequences. METHODS: We analysed 71 patients from 2 Rheumatology centres, 31 with DM and 40 with PM diagnosed according to the Bohan and Peter criteria...

Most studies about treatment of inflammatory myopathies consist of cross-sectional analyses that do not assess long-term efficacy. In the present study we describe the follow-up of seven patients with inflammatory myopathies, 5 polymyositis and 2 dermatomyositis. We describe their clinical features, follow-up, muscle enzyme levels, and treatment responses. We define the latter as treatment cycles, every one of which end when steroid doses need to be increased or a new immunosuppressive drug has to be added because of clinical worsening or sustained increases in muscle enzyme levels...

Febuxostat is an orally administered selective inhibitor of xanthine oxidase approved for the treatment of gout and prevention of tumor lysis syndrome. It is a relatively safe medication. Hypersensitivity reactions associated with the use of febuxostat are quite rare with only one reported case of DRESS syndrome. Recently, two case reports of rhabdomyolysis following the initiation of febuxostat were published. We hereby present the first case of rhabdomyolysis with hypereosinophilia following the administration of febuxostat to a 50-year-old patient newly diagnosed with marginal zone lymphoma...

PURPOSE OF REVIEW: This article provides guidelines for diagnosing and treating the different subtypes of autoimmune myopathies. RECENT FINDINGS: The most common subtypes of autoimmune myopathies are dermatomyositis, immune-mediated necrotizing myopathy, antisynthetase syndrome, and overlap syndromes; isolated polymyositis is an exceptionally rare disease. Specific autoantibodies are associated with unique clinical phenotypes and may be used for diagnostic and prognostic purposes, such as to assess the risk of coexisting malignancy...

Inflammatory myopathies are a heterogeneous group of immune-mediated diseases that involve the skeletal muscle as well as many other organs. In addition to a histological diagnosis at muscle biopsy, the clinical phenotypes of inflammatory myopathies can be defined by the presence of various autoantibodies that are originally detected by RNA or protein immunoprecipitation. However, the correlation between histological features and autoantibodies has not been fully elucidated. Immune-mediated necrotizing myopathy (IMNM), which is characterized by significant necrotic and regeneration muscle fibers with minimal or no inflammatory cell infiltration, is associated with the presence of autoantibodies...

Idiopathic inflammatory myopathies are historically classified into polymyositis and dermatomyositis based on the presence or absence of skin lesions. Recently, however, a more histology-oriented classification into 6 subtypes has been proposed. The subtypes include dermatomyositis, polymyositis, inclusion body myositis, immune-mediated necrotizing myopathy, anti-synthetase syndrome, and non-specific myositis. With strict criteria applied, polymyositis is now extremely rare, while immune-mediated necrotizing myopathy is the most common among all inflammatory myopathies and is often associated with autoantibodies including those for signal recognition particle (SRP) or 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR)...

The cytoskeleton is an integral part of skeletal muscle structure, and reorganization of the cytoskeleton occurs during various modes of remodeling. We previously found that the extracellular matrix protein secreted protein acidic and rich in cysteine (SPARC) is up-regulated and expressed intracellularly in developing muscle, during regeneration and in myopathies, which together suggests that SPARC might serve a specific role within muscle cells. Using co-immunoprecipitation combined with mass spectrometry and verified by staining for direct protein-protein interaction, we find that SPARC binds to actin...
