Anti-melanoma differentiation-associated protein 5 (MDA5) antibody have been found in dermatomyositis (DM)-associated interstitial lung disease (DM-ILD) and DM-associated rapidly progressive ILD (DM-RPILD). Due to the conflicting results regarding the association between anti-MDA5 antibody and DM-ILD or DM-RPILD and the diagnostic value of this antibody for DM-ILD and DM-RPILD, we performed this meta-analysis. A systematic search was performed to identify studies published to January 14, 2017. Sixteen publications with 491 DM with ILD versus 605 DM without ILD, as well as eighteen publications with 186 DM with RPILD and 790 DM without RPILD were included...

Dermatomyositis or polymyositis as a paraneoplastic syndrome of hepatocellular carcinoma (HCC) is an uncommon event. Few cases have been reported in the literature. We herein report the case of a 55-year-old man with chronic hepatitis B and alcoholism who presented with skin rash. Abdominal computed tomography revealed multiple hypervascular liver tumors consistent with HCC. He subsequently developed dysphagia with proximal limb weakness. Laboratory tests and electromyography demonstrated inflammatory myopathy...

OBJECTIVES: To evaluate the value of whole-body magnetic resonance imaging (WBMRI) in diagnosing muscular and extra muscular lesions in patients with polymyositis (PM) and dermatomyositis (DM). METHODS: A retrospective analysis of WBMRI data from PM/DM patients who met the Bohan and Peter diagnostic criteria was performed. X2 test was used to compare the rate of positive diagnosis of newly diagnosed patients using WBMRI, serum creatine kinase test, and EMG. McNemar test was used to compare the performance of WBMRI and chest CT in detecting interstitial lung disease (ILD)...

OBJECTIVE: Patients with polymyositis/dermatomyositis (PM/DM) who express anti-melanoma differentiation associated protein 5 (anti-MDA5) antibodies frequently present with interstitial lung disease (ILD). The aim of this study was to investigate the association of HLA-DRB1 with anti-MDA5 expression in PM/DM. METHODS: The frequency of DRB1 alleles was compared among 70 patients with PM, 104 patients with DM, and 400 healthy controls in a Han Chinese population. RESULTS: Frequencies of DRB1*04:01 [17...

OBJECTIVE: Interstitial lung disease (ILD) is involved in polymyositis/dermatomyositis (PM/DM), a disease associated with poor prognoses. Chitinase-3-like-1 protein (YKL-40) has pleiotropic biological activities involved in inflammation, cell proliferation, and tissue remodeling; however, the clinical application of YKL-40 remains limited. We investigated the clinical significance of YKL-40 in PM/DM-ILD. METHODS: Sixty-nine consecutive patients with PM/DM-ILD and 34 healthy controls were analyzed...

OBJECTIVES: An association between cancer and dermatomyositis (DM) is well recognized. The high frequency of malignancies detected close to DM diagnosis suggests that DM can be a paraneoplastic syndrome. Recently anti-TIF1-gamma has been discovered to be associated with cancer and DM. A meta-analysis claimed pooled sensitivity of anti-p155 for diagnosing cancer-associated DM to be 78% and specificity to be 89%. Thus anti-TIF1-gamma has shown promising results as a marker forcancer-associated DM ...

BACKGROUND: Juvenile Dermatomyositis (JDM) is a pediatric vasculopathy characterized primarily by skin and muscle involvement. Cardiac findings have been reported in children with JDM but have rarely been investigated in detail. METHODS: We aimed to describe the relevant clinical and laboratory cardiac findings of a cohort of patients with JDM, followed at one centre, at disease diagnosis. RESULTS: We performed a retrospective review of 105 patients with JDM, followed from 1991 to 2007...

Dermatomyositis is a rare heterogeneous systemic autoimmune disease with multiple organ involvement which can result in significant disability and mortality. Despite the lack of placebo-controlled trials, glucocorticoids are considered to be the mainstay of initial management. Treatment strategies are mainly based on uncontrolled studies, evidence based guidelines for treatments do not exist. Areas covered: This review provides an overview of the currently available pharmacological treatments in the field of dermatomyositis including conventional immunosuppressants, biologics and topical agents...

Mixed connective tissue disorder (MCTD) is a multisystem disease with overlapping features of other autoimmune diseases, such as systemic lupus erythematosus (SLE), myositis, rheumatoid arthritis, and scleroderma. MCTD presents with a distinctive antibody in serum known as U1-ribonucleoprotein (RNP). MCTD is quite rare as compared to other connective tissue disorders like SLE, systemic sclerosis, dermatomyositis, and polymyositis. We describe a case of MCTD in a young Asian female of 30 year old. This case highlights rare co-existence of polyneuropathy and autoamputation in MCTD disorder...

BACKGROUND: Sporadic inclusion body myositis (sIBM) is usually classified as an idiopathic inflammatory myopathies. Although the diagnosis of sIBM is sometimes challenging, recent studies have shown that the autoantibodies against cytosolic 5'-nucleotidase 1A (NT5C1A) are the possible diagnostic biomarker for sIBM. Few reports have shown the frequencies of anti-NT5C1A antibodies in systemic autoimmune rheumatic diseases (SARDs) using large cohorts of SARDs. METHODS: Serum samples obtained from 314 patients including dermatomyositis (DM) (n=144), systemic lupus erythematosus (SLE) (n=50), systemic sclerosis (SSc) (n=50), Sjögren's syndrome (SS) (n=50), polymyositis (PM) (n=10) and mixed connective tissue disease (n=10), and healthy controls (n=42) in addition to 10 patients with typical sIBM were analysed for the presence of autoantibodies using full-length recombinant NT5C1A ELISA...

This study describes the disease characteristics and outcome of Arab children with juvenile dermatomyositis (JDM) and compares the findings with other ethnicities. We retrospectively reviewed the hospital registries of the participating hospitals for children with JDM seen between 1990 and 2016 in three Arab countries. All patients fulfilled Bohan and Peter criteria for JDM, diagnosed before 14 years of age and were of Arab ethnicity. Clinical and laboratory features as well as the long-term outcomes including accrual disease damage were collected at the last follow-up visit...

OBJECTIVE: Low-density granulocytes (LDGs) can form neutrophil extracellular traps (NETs) spontaneously and excessively. When peripheral blood mononuclear cells (PBMCs) are used for studying T lymphocytes, LDGs contained in the PBMCs may decrease the threshold of activating T lymphocytes by forming NETs. This study focused on the profiles of LDGs in common autoimmune diseases and methods for removing LDGs from PBMCs. METHODS: The percentages of LDGs in PBMCs from 55 patients with dermatomyositis (DM), 15 with polymyositis (PM), 42 with rheumatoid arthritis (RA), 25 with systemic lupus erythematosus (SLE), and 19 healthy controls were determined by flow cytometry...

BACKGROUND: Anti-Su antibodies are found in 5-20% of cases of various systemic autoimmune rheumatic diseases and in 5-10% of dermatomyositis (DM)/polymyositis (PM) patients. In 2006, the 100kDa Su antigen was identified as argonaute2 (Ago2), and it was found to play a major role in RNA interference. However, immunoprecipitation (IP) remains the main method for detecting anti-Su and the clinical significance of the antibodies is uncertain. METHODS: Sera from patients with DM/PM (n=224) were screened by an ELISA that uses recombinant biotinylated Ago2 protein...

Lichen myxedematosus is an idiopathic, cutaneous mucinosis with 2 clinicopathologic subsets. There is the generalised papular and sclerodermoid form, more properly termed scleromyxedema, and the localised papular form. We report the first case, to our knowledge, of lichen myxedematosus in association with rheumatoid arthritis as well as a case in association with dermatomyositis. An up-to-date literature review on cutaneous mucinoses and connective tissue diseases, excluding the common association of primary and secondary mucinoses with systemic lupus erythematosus, was also performed...

OBJECTIVES: To provide an overview of the main naifold capillaroscopy (NFC) changes described in dermatomyositis (DM) and polymyositis (PM) and to discuss the current evidence supporting its clinical relevance and applications in daily practice. METHODS: All relevant literature in the field of NFC and DM and PM published in the last 30 years has been systematically reviewed. A systematic research was performed in the electronic databases PubMed and EMBASE. RESULTS: A total of 540 publications were identified according to the proposed filters and 27 were included for the review...
