Abstract
Dermatomyositis (DM) is an inflammatory myopathy often paraneoplastic in nature. Patients have characteristic cutaneous findings and possible muscle involvement. In the latter, muscle enzymes are elevated, and the electromyogram shows varied changes. Muscle or skin biopsy and myositis-specific antibodies confirm the diagnosis. Here, we report the case of an 86-year-old woman with cutaneous lesions, proximal weakness, and sicca symptoms. Muscle enzymes and electromyogram were normal. Antinuclear antibodies were elevated, and anti-TIF1γ and anti-Ro52 antibodies were positive. Muscle biopsy was compatible with the diagnosis of DM, and salivary gland biopsy confirmed Sjögren's syndrome. Malignancy investigation identified a rectal cancer, which was resected. This case illustrates a rare form of cancer presentation - anti-TIF1γ DM with normal muscle enzymes and electromyogram and concomitant secondary Sjögren's syndrome. Malignancy screening and multidisciplinary management were crucial to a successful approach.

Abstract
A diagnosis of polymyositis can readily be made when there is a typical history of proximal muscle weakness together with clinical findings, and there is corroboratory evidence in the form of elevated creatine kinase lactate dehydrogenase, aldolase, and serum glutamic-oxaloacetic transaminase (aspartate aminotransferase). A muscle biopsy usually helps in making the confirmatory diagnosis. A female in her 50s presented with non-healing multiple deep necrotic ulcers with muscle weakness. The initial possibility of vasculitis ulcers remained. Later, this proved to be a case of polymyositis with mildly elevated creatine kinase (which is usually not the case), atypical skin manifestations (usually there is no skin involvement), and negative extended myositis specific antibody panel with the growth of Burkholderia cepacia (perhaps the triggering factor). Hence, polymyositis can present with a myriad of atypical findings. Thus, thorough clinical examination and an integrated approach are necessary for early identification and treatment of the disease.

Usefulness and Clinical Impact of Whole-Body MRI in Detecting Autoimmune Neuromuscular Disorders. Brain Sci 2023; 13:1500. [PMID: 37891867 PMCID: PMC10605918 DOI: 10.3390/brainsci13101500] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2023] [Revised: 09/28/2023] [Accepted: 10/04/2023] [Indexed: 10/29/2023] Open
Abstract
Autoimmune neuromuscular diseases are a group of heterogenous pathologies secondary to the activation of the immune system that damage the structures of the peripheric nerve, the neuromuscular junction, or the skeleton muscle. The diagnosis of autoimmune neuromuscular disorders comprises a combination of data from clinical, laboratory, electromyography, imaging exam, and biopsy. Particularly, the whole-body MRI examination in the last two decades has been of great use in the assessment of neuromuscular disorders. MRI provides information about the structures involved and the status of activity of the disease. It can also be used as a biomarker, detect the pattern of specific muscle involvement, and is a useful tool for targeting the optimal muscle site for biopsy. In this work, we summarized the most used technical protocol of whole-body MRI and the role of this imaging technique in autoimmune neuromuscular disorders.

Abstract
OBJECTIVES Juvenile dermatomyositis (JDM) is a chronic autoimmune disease. Some patients remain in an active state even though they were administrated with a combination of corticosteroid and methotrexate. Existing research has suggested that interferon and Janus kinase played an important role in pathogenesis. Existing research has suggested the efficacy of JAK inhibitors (JAKi). Our retrospective study aimed to investigate the efficacy of tofacitinib in refractory JDM patients. METHODS A total of eighty-eight patients in China who had been diagnosed with JDM and subjected to tofacitinib therapy for over 3 months were retrospectively analyzed. Skin and muscle manifestations were assessed using the Cutaneous Assessment Tool-binary method (CAT-BM), Childhood Myositis Assessment Scale (CMAS), and kinase. Pulmonary function was assessed using a high-resolution CT (computerized tomography) scan and pulmonary symptoms. All patients were subjected to regular follow-up, and core measures were assessed every 3 months after initiation. Furthermore, the data were analyzed using the Wilcoxon single test, Mann-Whitney U test, and chi-square test. RESULTS Compared with the baseline data, skin and muscle manifestations were found significantly improved during the respective follow-up visit. At the most recent follow-up, nearly 50% of patients achieved a clinical complete response and six patients received tofacitinib monotherapy. Sixty percent of patients suffering from interstitial lung disease well recovered on high-resolution CT. Seventy-five percent of patients showed a reduction in the size or number of calcinosis, and 25% of patients showed completely resolved calcinosis. CONCLUSION In this study, the result suggested that tofacitinib therapy exerted a certain effect on skin manifestations, muscle manifestations, interstitial lung disease (ILD), calcinosis, as well as downgrade of medication. In-depth research should be conducted to focus on the correlation between the pathogenesis of JDM and JAKi.

Abstract
Polymyositis (PM) and dermatomyositis (DM) are rare idiopathic inflammatory myopathies (IIM). Myocardial involvement in patients with IIM is an unfavorable prognostic factor and one of the most common cause of mortality in this group of patients. The purpose of this review is to present current knowledge on cardiovascular manifestations observed in IIM. Data published in English until December 2021 were selected. Clinical symptoms suggesting cardiac involvement are non-specific and require a differential diagnosis in accordance with cardiological guidelines. Troponin I is specific to cardiac injury and should be preferred to other markers to evaluate the myocardium in IIM. Abnormalities in electrocardiography are common in IIM, especially non-specific changes of the ST-T segment. In standard echocardiography left ventricular diastolic dysfunction is reported frequently. New diagnostic technologies can reveal clinically silent myocardial abnormalities. However, the prognostic value of subclinical impairment of myocardial function require further studies.

Abstract
OBJECTIVES To evaluate the efficacy and safety of intravenous immunoglobulin (IVIG) in the treatment of dermatomyositis (DM) and polymyositis (PM). METHODS A comprehensive systematic review was conducted in accordance with the guidelines of PRISMA (Preferred Reporting Items for Systematic Reviews And Meta-analyses). PubMed, Embase, and China National Knowledge Infrastructure (CNKI) were searched to find articles published between July 1919 and May 2021 concerning IVIG therapy in PM/DM. We analyzed continuum data through mean difference and the estimated pooled improvement rate through Log transformation. We calculated all the effect measures with a 95% confidence interval. The I²statistic was calculated to assess statistical heterogeneity across the studies. I²values of 25%, 50% and 75% were defined as low, moderate and high, respectively. All analyses were conducted using R Studio, Version 3.6.3. RESULTS Seventeen papers pertinent to our questions were found: three case-control studies, fourteen non-randomized studies. We evaluated the efficacy of IVIG in DM/PM by the indicators of creatine kinase (CK), Manual Muscle Test (MMT) scores, Medical Research Council (MRC) scale, the Activities of Daily Living (ADL) scale and the pooled improvement rate. In a meta-analysis, we found that IVIG significantly improved the level of CK (SMD -0.69, 95%CI -0.93, -0.46; P<0.0001), MMT (SMD 1.12; 95%CI 0.77, 1.47; P<0.00001), MRC (SMD 1.59; 95%CI 0.86, 2.33; P<0.00001), ADL (SMD 1.07; 95%CI 0.59, 1.56; P<0.0001). The CK levels in DM and PM were also significantly improved after IVIG (SMD = -0.73, 95%CI -1.12, -0.34; P=0.0002; and SMD = -3.29, 95%CI -5.82, -0.76; P < 0.0001, respectively). The meta-analysis of three RCTs showed that there was a statistically significant improvement after IVIG (SMD 0.63; 95%CI 0.22, 1.03; P=0.002). In a random effects model pooled muscle power improvement rate was 77% (95% CI: 66.0-87.0%). Meta-analyses of IVIG as first-line therapy showed a significant improvement of CK level (SMD -0.71; 95%CI -1.12, -0.30; P=0.0007). In three studies, the polled improvement rate of esophageal disorders was 88% (95% CI: 80.0-95.0%). There was no statistically significant difference in the rate of improvement between the number of courses < 2 and ≥ 2 (0.80 vs. 0.80 %, P = 0.9). The corticosteroid-sparing effect of IVIG was also well demonstrated, with the proportion of corticosteroid-sparing success reaching 81.8% (72/88). Adverse reactions included headache, fever, Hypotension and dizzy and so on. Mild cortical stroke, staphylococcal septicaemia, asymptomatic myocardial infarction, cerebral infarction, deep vein thrombosis and subendocardial ischemia as severe adverse events were found in seven cases. CONCLUSION IVIG seems to be an effective drug for DM\PM, improving muscle strength, CK levels and esophageal involvement, and it is well tolerated by patients.

Abstract
While it took decades to arrive to a conclusion that ferritin is more than an indicator of iron storage level, it took a short period of time through the COVID-19 pandemic to wonder what the reason behind high levels of ferritin in patients with severe COVID-19 might be. Unsurprisingly, acute phase reactant was not a satisfactory explanation. Moreover, the behavior of ferritin in patients with severe COVID-19 and the subsequent high mortality rates in patients with high ferritin levels necessitated further investigations to understand the role of ferritin in the diseases. Ferritin was initially described to accompany various acute infections, both viral and bacterial, indicating an acute response to inflammation. However, with the introduction of the hyperferritinemic syndrome connecting four severe pathological conditions such as adult-onset Still's disease, macrophage activation syndrome, catastrophic antiphospholipid syndrome, and septic shock added another aspect of ferritin where it could have a pathogenetic role rather than an extremely elevated protein only. In fact, suggesting that COVID-19 is a new member in the spectrum of hyperferritinemic syndrome besides the four mentioned conditions could hopefully direct further search on the pathogenetic role of ferritin. Doubtlessly, improving our understanding of those aspects of ferritin would enormously contribute to better coping with severe diseases in terms of treatment and prevention of complications. The origin, history, importance, and the advances of searching the role of ferritin in various pathological and clinical processes are presented hereby in our article. In addition, the implications of ferritin in COVID-19 are addressed.

Abstract
HINTERGRUND Die Dermatomyositis gehört zur Gruppe der seltenen, idiopathischen, inflammatorischen Myositiden. Für die paraneoplastische Form der Dermatomyositis wurde in der Vergangenheit ein Zusammenhang mit Malignomen erkannt. Faktoren, die für eine Malignom-Assoziation sprechen, werden bis heute untersucht. PATIENTEN UND METHODIK Es wurden retrospektiv über einen Zeitraum von 15 Jahren die Daten von 63 Patienten mit Dermatomyositis analysiert. ERGEBNISSE Folgende Faktoren gaben einen Hinweis für eine Dermatomyositis mit Malignom-Assoziation: ein höheres Patientenalter (> 52 Jahre [P = 0,001], > 65 Jahre [P = 0,002], ≥ 75 Jahre [P = 0,002]), eine kürzere Zeit zwischen Erstmanifestation und Erstdiagnose (Malignom-Gruppe: 59 Tage vs. Nicht-Malignom-Gruppe: 137 Tage [P = 0,022]), eine Hautbeteiligung in Form von Gottron-Zeichen (P = 0,045), zentrofazialen Erythemen (P = 0,036) oder typischen Erythemen an den Ober-/Unterarmen (P = 0,019), eine oropharyngeale Beteiligung (P = 0,015) und eine GPT-Erhöhung (P = 0,031). Folgende Faktoren sprachen eher gegen eine Malignom-Assoziation: ein jüngeres Patientenalter (≤ 52 Jahre [P = 0,001], 40-65 Jahre [P = 0,045]) und Juckreiz (P = 0,026). SCHLUSSFOLGERUNGEN In der Literatur finden sich heterogene Ergebnisse zu den genannten Faktoren hinsichtlich ihrer Eignung als Marker für eine Malignom-Assoziation. Erschwert ist die Faktorenfindung aufgrund kleiner Studienpopulationen, wenigen prospektiven und kontrollierten Studien, die Einordnung von Populationen als Myositis-Patienten ohne Differenzierung und eine inkonsistente Verwendung der Nomenklatur. Mit unserer Studie wollen wir einen wichtigen Beitrag zur Identifizierung von Risikofaktoren bei Dermatomyositis mit Malignom-Assoziation leisten.

Abstract
BACKGROUND Dermatomyositis belongs to the rare idiopathic, inflammatory myositis group. A previously postulated link between some cases of dermatomyositis and malignancy has been established in recent years. Criteria suggestive of a malignancy association are still being explored. PATIENTS AND METHODS We retrospectively analyzed data from 63 patients with dermatomyositis over a period of 15 years. RESULTS The following criteria argue for cancer-associated dermatomyositis: older age (> 52 years [P = 0.001], > 65 years [P = 0.002], ≥ 75 years [P = 0.002]), shorter time between manifestation and diagnosis of dermatomyositis (malignancy group: 59 days vs. non-malignancy group: 137 days [P = 0.022]), typical skin involvement such as Gottron sign (P = 0.045), centrofacial erythema (P = 0.036) and typical erythema on the upper arms and forearms (P = 0.019), oropharyngeal involvement (P = 0.015) and increased ALT (P = 0.031). The following criteria argue for non-cancer-associated dermatomyositis: younger age (≤ 52 years [P = 0.001], 40-65 years [P = 0.045]) and pruritus (P = 0.026). CONCLUSIONS The aforementioned criteria have been documented in the literature, but reported findings are heterogenous concerning the suitability of their markers for malignancy association. Small study populations, few prospective controlled studies, summarization of different forms of myositis and inconsistent use nomenclature contribute to biased results. Our study aims to make an important contribution toward the identification of risk factors in cancer-associated dermatomyositis.

Abstract
Iron is an essential element required by cells and has been described as a key player in ferroptosis. Ferritin operates as a fundamental iron storage protein in cells forming multimeric assemblies with crystalline iron cores. We discuss the latest findings on ferritin structure and activity and its link to cell metabolism and ferroptosis. The chemistry of iron, including its oxidation states, is important for its biological functions, its reactivity, and the biology of ferritin. Ferritin can be localized in different cellular compartments and secreted by cells with a variety of functions depending on its spatial context. Here, we discuss how cellular ferritin localization is tightly linked to its function in a tissue-specific manner, and how impairment of iron homeostasis is implicated in diseases, including cancer and coronavirus disease 2019. Ferritin is a potential biomarker and we discuss latest research where it has been employed for imaging purposes and drug delivery.

Prevalence of Nasopharyngeal Carcinoma in Patients with Dermatomyositis: A Systematic Review and Meta-Analysis. Cancers (Basel) 2021; 13:cancers13081886. [PMID: 33919987 PMCID: PMC8071042 DOI: 10.3390/cancers13081886] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2021] [Revised: 03/25/2021] [Accepted: 04/03/2021] [Indexed: 01/02/2023] Open
Abstract
Simple Summary This first systematic review and meta-analysis on the prevalence of nasopharyngeal carcinoma in patients suffering dermatomyositis was necessitated by the absence of a true and reliable prevalence estimate necessary to adequately inform medical preparedness and decisions. Following a careful review of literature and data analyses, a prevalence of 3.3% was found. It is hoped that a clear knowledge of the actual prevalence of nasopharyngeal carcinoma in dermatomyositis patients would not only help sensitize clinicians and patients about the frequency of these disease conditions but would also enhance the adoption of precautions essential to mitigate their co-occurrence in patients. Abstract For more than 50 years, nasopharyngeal carcinoma (NPC) has been associated with dermatomyositis (DM), a rare idiopathic inflammatory disorder that mainly affects the skin and muscles. Although the association between these rare diseases is well-documented, the actual prevalence of NPC in DM patients remains unknown. Here, a systematic review and meta-analysis of published data was conducted in accordance with the guidelines of Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA). Electronic databases including PubMed, Scopus, ScienceDirect, and Google Scholar were searched without year or language restrictions for studies reporting the occurrence of NPC in DM patients. The study protocol was lodged with PROSPERO (CRD42021225335). A total of 95 studies covering 303 cases of NPC among 16,010 DM patients was included. Summary estimates were calculated using the random-effects model. The pooled prevalence of NPC in DM was 3.3% (95% CI, 2.5–4.3). When stratified according to study location, higher prevalence estimates were obtained for Hong Kong (36.5%), Malaysia (27.7%), and Singapore (11.9%). There was a predominance of cases among male DM patients compared with females, and most patients were aged 40 and above. Many of the NPC cases were found to be diagnosed after the diagnosis of DM. It is therefore pertinent to screen for NPC in DM patients, especially among older DM patients in the Asian region.

Abstract
La dermatomyosite (DM) et la polymyosite (PM) sont des affections rares mais graves. Le but de ce travail est d'étudier, à travers la revue d'une série hospitalière, leur profil épidémiologique, clinique et évolutif. Il s´agit d´une étude rétrospective, conduite sur une période de 15 ans, entre janvier 2004 et décembre 2019. Ont été retenus les cas où le diagnostic était certain ou probable selon les critères de Bohan et Peter. Un total de 14 patients ont été inclus (8 DM et 6 PM), l´âge moyen était de de 48,7 ans. La sex-ratio était de 13F/1H. Les signes généraux existaient dans 71%. Le déficit moteur touchait les muscles des ceintures dans 71% des cas; 85,7% avaient des arthralgies et 14% des arthrites. L´érythème et l´œdème périorbitaire étaient les signes cutanés prédominants. Au bilan, la vitesse de sédimentation était accélérée chez tous les malades et les enzymes musculaires augmentées dans 80%. Les anticorps anti-nucléaires étaient positifs dans 63%. La biopsie musculaire a retrouvé une myosite inflammatoire dans 75%. L'atteinte cardiaque existait dans 14% des cas et pulmonaire dans 21%. Un cancer était associé dans 21,4% des cas. Tous les patients ont reçu une corticothérapie. L´évolution s´est faite vers l´amélioration dans 88%, avec une rechute chez 4 patientes. Dans notre contexte, la DM est plus fréquente que la PM, avec nette prédominance féminine. L'atteinte pulmonaire reste une complication lourde. L´association aux cancers semble fréquente d´où la nécessité d´un bilan systématique de néoplasie au moment du diagnostic et lors du suivi.

[PMID: 32650400 PMCID: PMC7408750 DOI: 10.3390/jcm9072150] [Citation(s) in RCA: 30] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2020] [Revised: 07/01/2020] [Accepted: 07/06/2020] [Indexed: 12/14/2022] Open
Abstract
(1) Background: Dysphagia is a clinical hallmark and part of the current American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) diagnostic criteria for idiopathic inflammatory myopathy (IIM). However, the data on dysphagia in IIM are heterogenous and partly conflicting. The aim of this study was to conduct a systematic review on epidemiology, pathophysiology, outcome and therapy and a meta-analysis on the prevalence of dysphagia in IIM. (2) Methods: Medline was systematically searched for all relevant articles. A random effect model was chosen to estimate the pooled prevalence of dysphagia in the overall cohort of patients with IIM and in different subgroups. (3) Results: 234 studies were included in the review and 116 (10,382 subjects) in the meta-analysis. Dysphagia can occur as initial or sole symptom. The overall pooled prevalence estimate in IIM was 36% and with 56% particularly high in inclusion body myositis. The prevalence estimate was significantly higher in patients with cancer-associated myositis and with NXP2 autoantibodies. Dysphagia is caused by inflammatory involvement of the swallowing muscles, which can lead to reduced pharyngeal contractility, cricopharyngeal dysfunction, reduced laryngeal elevation and hypomotility of the esophagus. Swallowing disorders not only impair the quality of life but can lead to serious complications such as aspiration pneumonia, thus increasing mortality. Beneficial treatment approaches reported include immunomodulatory therapy, the treatment of associated malignant diseases or interventional procedures targeting the cricopharyngeal muscle such as myotomy, dilatation or botulinum toxin injections. (4) Conclusion: Dysphagia should be included as a therapeutic target, especially in the outlined high-risk groups.

Abstract
OBJECTIVES Anti-melanoma differentiation-associated gene 5 (MDA5) autoantibody-positive and age at onset ≥60 years are poor prognosis factors in polymyositis (PM) and dermatomyositis (DM) associated with interstitial lung disease (ILD) among Japanese patients. However, the influence of age on the clinical features of anti-MDA5 autoantibody-positive patients with DM remains unclear. METHODS We retrospectively examined 40 patients with DM and anti-MDA5 autoantibodies according to age. We compared patients aged <60 and ≥60 years with respect to clinical features including laboratory test findings, high-resolution lung computed tomography data, treatment content, and complications such as infections and prognosis. We also examined clinical features between surviving and deceased patients in the older patient group. RESULTS Of 40 enrolled patients, 13 were classified as old and 27 as young. Older patients had significantly fewer clinical symptoms including arthralgia/arthritis (p < .01), skin ulceration (p = .02), and higher mortality than younger patients (p = .02) complicated with rapidly progressive ILD (RP-ILD), combination immunosuppressive therapy, and strictly controlled infections. CONCLUSION Clinical features and mortality of anti-MDA5 autoantibody-positive DM patients were influenced by age. Patients aged ≥60 years had a worse prognosis, and combination immunosuppressive therapy was often ineffective for RP-ILD in older patients.

Abstract
Polymyositis (PM) and dermatomyositis (DM) are different disease subtypes of idiopathic inflammatory myopathies (IIMs). The main clinical features of PM and DM include progressive symmetric, predominantly proximal muscle weakness. Laboratory findings include elevated creatine kinase (CK), autoantibodies in serum, and inflammatory infiltrates in muscle biopsy. Dermatomyositis can also involve a characteristic skin rash. Both polymyositis and dermatomyositis can present with extramuscular involvement. The causative factor is agnogenic activation of immune system, leading to immunologic attacks on muscle fibers and endomysial capillaries. The treatment of choice is immunosuppression. PM and DM can be distinguished from other IIMs and myopathies by thorough history, physical examinations and laboratory evaluation and adherence to specific and up-to-date diagnosis criteria and classification standards. Treatment is based on correct diagnosis of these conditions. Challenges of diagnosis and management influences the clinical research and practice of Polymyositis and dermatomyositis. Diagnostic criteria have been updated and novel therapies have been developed in PM/DM. Pathogenesis investigation and diagnosis precision improvement may help to guide future treatment strategies.

Abstract
Dysphagia can be predominant or sole symptom of myositis. However, diagnostic evaluation is difficult in such cases. Here, we present evidence for dysphagia as sole manifestation of Jo-1 associated myositis. A 77-year-old patient suffering from isolated dysphagia was assessed by flexible endoscopic evaluation of swallowing, videofluoroscopy, high resolution esophageal manometry, whole body muscle MRI, electroneurographic and electromyographic examination, cerebrospinal fluid analysis, screening for autoantibodies, and body plethysmography. We detected isolated oropharyngeal dysphagia including a decreased pressure of the upper esophageal sphincter leading to cachexia in an anti-Jo-1 positive patient without any abnormalities in the other diagnostics. Immunosuppressive therapy with cortisone and azathioprine led to long-term improvement of dysphagia. This is the first report of isolated dysphagia as manifestation of Jo-1 associated myositis. Therefore, Jo-1 associated myositis should be considered as a possible differential diagnosis for isolated dysphagia. Typical signs for myositis in instrumental dysphagia assessment are presented.

Abstract
AIM The prevalence and diagnostic values of myositis-specific autoantibodies (MSAs) and myositis-associated autoantibodies (MAAs) in dermatomyositis/polymyositis (DM/PM) were studied. METHOD A commercial immunoblot assay with 16 autoantigens was used to detect MSAs and MAAs in serum samples from 130 DM/PM patients, 100 disease controls, and 50 healthy subjects. RESULTS The prevalence of anti-Jo-1, anti-MDA5, anti-TIF1γ, anti-Mi-2α, and anti-Mi-2β was significantly higher in DM/PM than in other connective-tissue diseases (CTDs). Moreover, anti-MDA5 and anti-Ro-52 were significantly higher in DM/PM with interstitial lung disease (ILD) than in DM/PM without ILD, while that of anti-TIF1γ and anti-NXP2 were significantly lower in DM/PM with ILD than in DM/PM without ILD. For distinguishing DM/PM from other CTDs, the sensitivity, specificity, and positive predictive value (PPV) for anti-MDA5 were 28.46, 99.00, and 97.37%, respectively, with a positive likelihood ratio (LR+) of 28.46; they were 46.15, 58.00, and 58.82%, respectively, for anti-Ro-52 with an LR+ of 1.10. For distinguishing DM/PM with ILD from DM/PM without ILD, the sensitivity, specificity, and PPV for anti-MDA5 were 45.57, 100.00, and 100.00%, respectively, and for anti-Ro-52 were 60.76, 73.91, and 80.00%, respectively. CONCLUSION MSAs and MAAs serve as biomarkers for differentiating DM/PM from other CTDs as well as distinguishing DM/PM with ILD from DM/PM without ILD.

Abstract
Although rheumatologists, neurologists and dermatologists see patients with polymyositis (PM) and dermatomyositis (DM), their management appears to vary depending on the physician's specialty. The aim of the present study was to establish the treatment consensus among specialists of the three fields to standardize the patient care. We formed a research team supported by a grant from the Ministry of Health, Labor and Welfare, Japan. Clinical questions (CQ) on the management of PM and DM were raised. A published work search on CQ was performed primarily using PubMed. Using the nominal group technique, qualified studies and results in the published work were evaluated and discussed to reach consensus recommendations. They were sent out to the Japan College of Rheumatology, Japanese Society of Neurology and Japanese Dermatological Association for their approval. We reached a consensus in 23 CQ and made recommendations and a decision tree for management was proposed. They were officially approved by the three scientific societies. In conclusion, a multidisciplinary treatment consensus for the management of PM and DM was established for the first time.

Abstract
Dermatomyositis is a multisystem disease manifesting as an idiopathic inflammatory myopathy, characterised predominantly by cutaneous and muscular abnormalities. Patients with dermatomyositis display characteristic skin changes in addition to muscle weakness. Many consider dermatomyositis a paraneoplastic syndrome, as up to 32% of patients with dermatomyositis will develop cancer. Discussed here is the case of a 69-year-old man with a new diagnosis of dermatomyositis who was referred to a tertiary institution with an 8-month history of rash, proximal muscle weakness, fatigue and weight loss. In the absence of clinical symptoms, negative cancer markers and a negative CT chest, abdomen and pelvis, positron emission tomography-CT prompted a gastroscopy, which led to the discovery of a stage T1b oesophageal adenocarcinoma. The oesophageal adenocarcinoma was treated with a gastrointestinal endoscopic mucosal resection and subsequent oesophajectomy. The patient's dermatomyositis was treated successfully with oral prednisolone and methotrexate.

Abstract
The major forms of autoimmune myopathies include dermatomyositis (DM), polymyositis (PM), myositis associated with antisynthetase syndrome (ASS), immune-mediated necrotizing myopathy (IMNM), and inclusion body myositis (IBM). While each of these conditions has unique clinical and histopathological features, they all share an immune-mediated component. These conditions can occur in isolation or can be associated with systemic malignancies or connective tissue disorders (overlap syndromes). As more has been learned about these conditions, it has become clear that traditional classification schemes do not adequately group patients according to shared clinical features and prognosis. Newer classifications are now utilizing myositis-specific autoantibodies which correlate with clinical and histopathological phenotypes and risk of malignancy, and help in offering prognostic information with regard to treatment response. Based on observational data and expert opinion, corticosteroids are considered first-line therapy for DM, PM, ASS, and IMNM, although intravenous immunoglobulin (IVIG) is increasingly being used as initial therapy in IMNM related to statin use. Second-line agents are often required, but further prospective investigation is required regarding the optimal choice and timing of these agents.

SAGE Open Med 2018; 6:2050312118781895. [PMID: 29977547 PMCID: PMC6024348 DOI: 10.1177/2050312118781895] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2017] [Accepted: 05/14/2018] [Indexed: 01/21/2023] Open
Abstract
Objective: To examine the clinical utility of tumor markers in dermatomyositis/polymyositis patients in Taiwan. Method: Data were collected retrospectively from the database of Taichung Veterans General Hospital in Taiwan from 1998 to 2014. Patients who fulfilled Bohan and Peter criteria of dermatomyositis/polymyositis were recruited. Serum level of tumor markers including carcinoembryonic antigen, alpha-fetoprotein, carbohydrate antigen 125, carbohydrate antigen 19-9 and carbohydrate antigen 15-3 were measured. The occurrence of malignancies and interstitial lung disease was identified. The association of tumor markers with malignancies and interstitial lung disease was examined using Chi-square test or Fisher’s exact test. Results: Among the enrolled 151 patients, 98 (64.9%) dermatomyositis and 53 (35.1%) polymyositis, a total of 15 malignancies were detected: breast ductal carcinoma (n = 4), bladder transitional cell carcinoma (n = 2), lung adenocarcinoma (n = 2), cervical intraepithelial neoplasia 3 and papillary squamous cell carcinoma (n = 2), colorectal (colon and rectal adenocarcinoma) (n = 2), uterine adenocarcinoma (n = 1), nasopharyngeal carcinoma (n = 1) and hematological malignancy (myelodysplastic with excess blast cells) (n = 1). Among the patients with malignancies, 13 (86.7%) had dermatomyositis, 2 (13.3%) polymyositis and 3 (20%) interstitial lung disease. The mean duration from dermatomyositis/polymyositis diagnosis to the occurrence of malignancies was 6.05 ± 5.69 years. There was no significant association of raised tumor markers with the occurrence of malignancies (p > 0.085), while a significant association was observed between the elevated levels of carbohydrate antigen 15-3 and the presence of interstitial lung disease (p = 0.006). Conclusion: Tumor markers were not useful in malignancy screening or dermatomyositis/polymyositis patients in this tertiary center. The evaluation of the occurrence of malignancy in dermatomyositis/polymyositis patient should include a multidimensional approach. A raised level of carbohydrate antigen 15-3 may be a potential indicator of the presence of interstitial lung disease in dermatomyositis/polymyositis patients.

Abstract
BACKGROUND Interstitial lung disease (ILD) is the principal cause of death in polymyositis/dermatomyositis (PM/DM). Here we investigated prognostic factors for death and serious infection in PM/DM-ILD using the multicenter database. METHODS We retrospectively reviewed baseline demographic, clinical and laboratory findings, treatment regimens and outcomes in patients with PM/DM-ILD. The distribution of ILD lesions was evaluated in four divided lung zones of high-resolution computed tomography images. RESULTS Of 116 patients with PM/DM-ILD, 14 died within 6 months from the diagnosis. As independent risk factors for early death, extended ILD lesions in upper lung fields (odds ratio (OR) 8.01, p = 0.016) and hypocapnia (OR 6.85, p = 0.038) were identified. Serious infection was found in 38 patients, including 11 patients who died of respiratory or multiple infections. The independent risk factors were high serum KL-6 (OR 3.68, p = 0.027), high initial dose of prednisolone (PSL) (OR 4.18, p = 0.013), and combination immunosuppressive therapies (OR 5.51, p < 0.001). CONCLUSION The present study shows the progression of ILD at baseline is the most critical for survival and that infection, especially respiratory infection, is an additive prognostic factor under the potent immunosuppressive treatment.

Abstract
The idiopathic inflammatory myopathies (IIMs) are a heterogeneous group of autoimmune diseases (collectively known as myositis) affecting the skeletal muscles as well as other organ systems such as skin, lungs, and joints. The primary forms of myositis include polymyositis (PM), dermatomyositis (PM), and immune-mediated necrotizing myopathy (IMNM). Patients with these diseases experience progressive proximal muscle weakness, have characteristic muscle biopsy findings, and produce autoantibodies that are associated with unique clinical features. One distinguishing feature of these patients is that they are also known to have an increased risk of cancer. Since the first description of the association in 1916, it has been extensively reported in the medical literature. However, there have been significant variations between the different studies with regard to the degree of cancer risk in patients with IIM. These discrepancies can, in part, be attributed to differences in the definition of malignancy-associated myositis used in different studies. In recent years, significant advances have been made in defining specific features of IIM that are associated with the development of malignancy. One of these has been myositis-specific antibodies (MSAs), which are linked to distinct clinical phenotypes and categorize patients into groups with more homogeneous features. Indeed, patients with certain MSAs seem to be at particularly increased risk of malignancy. This review attempts a systematic evaluation of research regarding the association between malignancy and myositis.

Abstract
OBJECTIVE Patients with immune-mediated necrotizing myopathy (IMNM) often have autoantibodies recognizing the signal recognition particle (SRP) or HMG-CoA reductase (HMGCR). Here, we studied a cohort of anti-SRP patients to identify factors associated with disease severity and clinical improvement; we also compared the severity of weakness in those with anti-SRP versus anti-HMGCR autoantibodies. METHODS All anti-SRP patients in the Johns Hopkins Myositis Cohort from 2002 to 2015 were included. Longitudinal information regarding proximal muscle strength, creatine kinase (CK) levels, and immunosuppressive therapy was recorded at each visit. Univariate and multivariate multilevel regression models were used to assess prognostic factors influencing recovery. Strength in the anti-SRP patients was compared to strength in 49 previously described anti-HMGCR subjects. RESULTS Data from 37 anti-SRP patients and 380 total clinic visits were analyzed. Younger age at onset was associated with more severe weakness at the first visit (P = 0.02) and all subsequent visits (P = 0.002). Only 50% of patients reached near-full or full strength after 4 years of treatment, and most of these continued to have elevated CK levels. Rituximab appeared to be effective in 13 of 17 anti-SRP patients. Anti-SRP patients were significantly weaker than those with anti-HMGCR autoantibodies (-1.3 strength points; P = 0.001). CONCLUSION Younger age at onset is associated with more severe weakness in anti-SRP myositis. Furthermore, even among anti-SRP patients whose strength improved with immunosuppression, most had ongoing disease activity as demonstrated by elevated CK levels. Finally, anti-SRP patients were significantly weaker than anti-HMGCR patients, providing evidence that these autoantibodies are associated with distinct forms of IMNM.

Abstract
Dermatomyositis and polymyositis may affect children and adults and are now widely recognized as major causes of disability which, thanks to the introduction of immunosuppressive drugs, is often treatable, at least to some extent. Few data exist regarding polymyositis in elderly patients. We describe a case of refractory life-threatening polymyositis in an elderly patient, successfully treated with intravenous cyclophosphamide.

Abstract
This study aims to investigate the prevalence and predictive risk factors of malignancy in patients with polymyositis (PM) and dermatomyositis (DM). The medical records of 192 PM/DM patients followed up in a medical center between January 2000 and December 2013 were reviewed. Among the 192 patients, 33 patients (17.2 %) had associated cancer. Both PM and DM are significantly associated with cancer, although the risk of cancer appears to be somewhat higher among patients with DM (23.0 %) than among those with PM (8.9 %). Nasopharyngeal cancer (30.3 %) and breast cancer (18.2 %) comprised the most common malignant diseases associated with PM/DM. Univariate analysis showed that an older age at PM/DM onset, heliotrope rash, Gottron's sign, dysphagia, and low creatine phosphokinase (CPK) level were associated with increased malignancy. Multivariate analysis revealed that independent predictors of malignancy in PM/DM were age >40 years at PM/DM onset (adjusted OR 3.44; 95 % CI 1.08-10.98; p = 0.037) and heliotrope rash (adjusted OR 2.96; 95 % CI 1.04-8.43; p = 0.042). During the follow-up period, 66 (34.4 %) patients died and the overall patient survival rates were 83.1 % at 1 year, 78.9 % at 2 years, 74.2 % at 5 years, and 65.5 % at 10 years. This study demonstrates a high frequency of malignancy (17.2 %) in DM/PM patients. Nasopharyngeal cancer and breast cancer were the most common cancer types in DM/PM patients in our study. Cancer screening should be offered to patients with newly diagnosed DM/PM. Moreover, all patients should be evaluated for the possibility of an underlying malignancy during treatment.

Abstract
Polymyositis and dermatomyositis are inflammatory myopathies that differ in their clinical features, histopathology, response to treatment, and prognosis. Although their clinical pictures differ, they both present with symmetrical, proximal muscle weakness. Treatment relies mainly upon empirical use of corticosteroids and immunosuppressive agents. A deeper understanding of the molecular pathways that drive pathogenesis, careful phenotyping, and accurate disease classification will aid clinical research and development of more efficacious treatments. In this review we address the current knowledge of the epidemiology, clinical characteristics, diagnostic evaluation, classification, pathogenesis, treatment, and prognosis of polymyositis and dermatomyositis.

Abstract
Dermatomyositis is a life-altering inflammatory disorder of skin and muscle. Details regarding the natural course of this disorder, the effects of specific therapies on its progression, and the optimal therapeutic dosage and duration of prednisone are limited. We performed a retrospective medical record review of dermatomyositis patients at four medical centers. All patients were over the age of 21 and had a clinical diagnosis of dermatomyositis with pathological confirmation. We reviewed average muscle strength, corticosteroid use, creatine kinase levels, and supplemental immunosuppressant use during the 36-month period following each patient's initial assessment. One hundred patients participated with an average age of 50.1 years. Average muscle strength improved and prednisone requirements lessened six months after initial assessment. There was no difference in the mean change in muscle strength or cumulative corticosteroid use over 36 months among those initially treated with methotrexate, mycophenolate mofetil, pulse IVIG, or azathioprine. There was a 5% mortality rate in dermatomyositis patients due to infections. Treated dermatomyositis patients demonstrate the most significant improvement in strength during the first six-to-twelve months following their initial clinical assessment. Additional prospective studies are needed to determine the relative benefit of select immunosuppressant agents in preserving strength and reducing corticosteroid use in dermatomyositis.

Abstract
BACKGROUND Dermatomyositis affects striated muscles, skin and other organs. OBJECTIVE To characterize the disease from January 1992 to December 2002, assessing its
classification, cutaneous and systemic manifestations, and also laboratory
results, therapeutic and prognostic findings compared to those in the
literature. METHODS Data were obtained from medical records of 109 patients who were classified into
five groups: 23 juvenile dermatomyositis; 59 primary idiopathic dermatomyositis; 6
amyopathic dermatomyositis; 7 dermatomyositis associated with neoplasms and 14
dermatomyositis associated with other connective tissue diseases. RESULTS Sixty patients were classified as "definite" diagnosis; 33 as "possible"; four as
"probable" and 12 and as amyopathic. The average age at diagnosis was 36 years.
Cutaneous manifestations occurred in all patients; the most frequent symptom was
loss of proximal muscle strength; the most common pulmonary disorder was
interstitial lung disease, and gastritis was the most prevalent digestive
manifestation. Tumors were documented in 6.42% of cases. Lactate dehydrogenase was
the muscle enzyme most frequently elevated in the majority of cases. Skin biopsies
were performed in 68 patients; muscle biopsies in 53; and electroneuromyographies
in 58 patients. The most commonly used treatment was corticotherapy and the
mortality rate was 14.7%. CONCLUSION in this sample, the disease appeared in younger individuals, was more frequent in
women and the association with cancer was small.

Abstract
The idiopathic inflammatory myopathies (IIM) consist of rare heterogeneous autoimmune disorders that present with marked proximal and symmetric muscle weakness, except for distal and asymmetric weakness in inclusion body myositis. Despite many similarities, the IIM are fairly heterogeneous from the histopathologic and pathogenetic standpoints, and also show some clinical and treatment-response differences. The field has witnessed significant advances in our understanding of the pathophysiology and treatment of these rare disorders. This review focuses on dermatomyositis, polymyositis, and necrotizing myopathy, and examines current and promising therapies.

Abstract
The aim of this work is to evaluate disease-related mortality and the course of the disease including functional outcome and quality of life. We did a follow-up study on a large prospective cohort of 62 patients with subacute-onset idiopathic inflammatory myopathy (IIM) (dermatomyositis (n = 24), nonspecific myositis (n = 34), necrotizing autoimmune myopathy (n = 4)) after treatment with corticosteroids only (randomized controlled trial comparing daily high-dosage prednisone with pulse therapy of dexamethasone). Development of connective tissue disease (CTD) or malignancy, disease course and mortality, functional outcome and quality of life were evaluated. After a mean follow-up of 3 years (SD 1.5), 22 % had developed a CTD and 17 % a malignancy. Disease-related mortality was 15 %. A monophasic disease course was found in 27 %. Most patients had a chronic (35 %) or polyphasic disease (35 %) course and experienced single or multiple relapses. Sixteen patients (33 %) were off medication after a mean of 1 year of treatment. Disability scores improved particularly in the first 18 months. At follow-up, 68 % still perceived disabilities. Quality of life scores as measured by the short-form (SF)-36 improved in the first 18 months. After 18 months, scores remained stable during the next years of follow-up and remained low compared to a normal population. (1) Two-thirds of the patients with an IIM have a polyphasic or chronic disease course and need maintenance treatment. (2) The impact on functional outcome and quality of life is considerable and does not improve further after 18 months.

Abstract
OBJECTIVE Our aim was to report our experience with inflammatory myositis. MATERIAL AND METHODS In total, 60 patients were evaluated retrospectively, and 43 of them (71.7%) were female. The median age was 45 (17-81). Of all patients, 33 (55%) were diagnosed as polymyositis, 22 (36.6%) as dermatomyositis (classical, amyopathic, and malignancy-associated), and 5 (8.33%) as undifferentiated myositis. The 3 patients with malignancy-associated dermatomyositis had lung cancer, nasopharyngeal carcinoma, and endometrial cancer. Two patients with polymyositis had a history of low-grade gastric mixed tumor and thymoma but were diagnosed 7 and 12 years ago, and no recurrences have been reported during the routine controls. RESULTS All patients, other than two with malignancy-associated dermatomyositis, were treated via immunosuppressive agent, and the third patient with lung cancer was diagnosed later and gave up immunosuppressive therapy. Thirty-nine (65%) of the patients were treated via oral low-dose steroid, and 19 (31.7%) were treated via intravenous high-dose pulse steroid therapy. All patients were treated with steroid, which was tapered by time, and 23 (38.3%) were treated with azathioprine, 6 (10%) were treated with cyclophosphamide, 3 (5%) were treated with methotrexate, and 6 (10%) were treated with isolated steroid therapy at the time of diagnosis. The median follow-up period was 37 (2-135) months. Six patients (10%) have died-3 due to myocardial infarction, 1 due to septic shock, 1 due to malignancy, and 1 with an unknown reason. The 5-year survival rate was 76.9%, and the 10-year survival rate was 40%. CONCLUSION Other than the high ratio of PM in our series, all other results were compatible with the literature. We faced few resistant diseases; therefore, biologic agents were used rarely.

Abstract
Autoimmune diseases may reveal or occur during the course of a neoplasia or its treatment. Autoimmune cytopenia, especially haemolytic anaemia, is common in lymphoproliferative disorders such as chronic lymphoid leukemia. The link between cancer and myositis is well established. Dermatomyositis is associated with an increased relative risk of cancer of 3.4 to 4.4. A combination of detection of antibodies against p155 and TEP-computed tomography may be the best approach to ascertain the presence of occult malignancy in patients with dermatomyositis. A cutaneous or a systemic vascularitis may reveal a cancer, most often a haematological malignancy such as hairy cell leukemia. Paraneoplastic polyarthritis have been described in particular with adenocardinoma of the lungs. Underlying neoplasia should be considered in male smokers patients with new onset polyarthritis and poor health status. The prevalence of autoimmune conditions in myelodysplastic syndromes is 10 to 30%. Vasculitis and relapsing polychondritis are the most commonly reported manifestations. Immune manifestations can also be related to treatment. The most common treatment complications are autoimmune haemolytic anaemia with fludarabine and thyroiditis related to interferon and cervical radiotherapy.

Abstract
A 55-year-old woman with dermatomyositis and small cell lung cancer was successfully treated with surgery followed by combination chemotherapy in 1987. She had been in remission without further immunosuppressive therapy for 10 years. However, myositis with cutaneous manifestations specific for dermatomyositis relapsed when the patient was 69 years old. Intensive examinations revealed no neoplasm, and she responded to a moderate dose of systemic corticosteroids. This case suggests a long-lasting autoimmune abnormality in dermatomyositis and that a neoplasm is an important factor in eliciting an occult dermatomyositis.

Abstract
OBJECTIVE To identify the clinical and laboratory predictors of clinical improvement in a cohort of myositis patients treated with rituximab. METHODS We analyzed data for 195 patients with myositis (75 with adult polymyositis [PM], 72 with adult dermatomyositis [DM], and 48 with juvenile DM) in the Rituximab in Myositis trial. Clinical improvement was defined as 20% improvement in at least 3 of the following 6 core set measures of disease activity: physician's and patient's/parent's global assessment of disease activity, manual muscle testing, physical function, muscle enzymes, and extramuscular disease activity. We analyzed the association of the following baseline variables with improvement: myositis clinical subgroup, demographics, myositis damage, clinical and laboratory parameters, core set measures, rituximab treatment, and myositis autoantibodies (antisynthetase, anti-Mi-2, anti-signal recognition particle, anti-transcription intermediary factor 1γ [TIF-1γ], anti-MJ, other autoantibodies, and no autoantibodies). All measures were univariately assessed for association with improvement using time-to-event analyses. A multivariable time-dependent proportional hazards model was used to evaluate the association of individual predictive factors with improvement. RESULTS In the final multivariable model, the presence of an antisynthetase, primarily anti-Jo-1 (hazard ratio [HR] 3.08, P < 0.01), anti-Mi-2 (HR 2.5, P < 0.01), or other autoantibody (HR 1.4, P = 0.14) predicted a shorter time to improvement compared to the absence of autoantibodies. A lower physician's global assessment of damage (HR 2.32, P = 0.02) and juvenile DM (versus adult myositis) (HR 2.45, P = 0.01) also predicted improvement. Unlike autoantibody status, the predictive effect of physician's global assessment of damage and juvenile DM diminished by week 20. Rituximab treatment did not affect these associations. CONCLUSION Our findings indicate that the presence of antisynthetase and anti-Mi-2 autoantibodies, juvenile DM subset, and lower disease damage strongly predict clinical improvement in patients with refractory myositis.

Abstract
Peak age at onset of systemic sclerosis (SSc) is between 20 and 50 years, although SSc is also described in both young and elderly patients. We conducted the present study to determine if age at disease onset modulates the clinical characteristics and outcome of SSc patients. The Spanish Scleroderma Study Group recruited 1037 patients with a mean follow-up of 5.2 ± 6.8 years. Based on the mean ± 1 standard deviation (SD) of age at disease onset (45 ± 15 yr) of the whole series, patients were classified into 3 groups: age ≤ 30 years (early onset), age between 31 and 59 years (standard onset), and age ≥ 60 years (late onset). We compared initial and cumulative manifestations, immunologic features, and death rates. The early-onset group included 195 patients; standard-onset group, 651; and late-onset, 191 patients. The early-onset group had a higher prevalence of esophageal involvement (72% in early-onset compared with 67% in standard-onset and 56% in late-onset; p = 0.004), and myositis (11%, 7.2%, and 2.9%, respectively; p = 0.009), but a lower prevalence of centromere antibodies (33%, 46%, and 47%, respectively; p = 0.007). In contrast, late-onset SSc was characterized by a lower prevalence of digital ulcers (54%, 41%, and 34%, respectively; p < 0.001) but higher rates of heart conduction system abnormalities (9%, 13%, and 21%, respectively; p = 0.004). Pulmonary hypertension was found in 25% of elderly patients and in 12% of the youngest patients (p = 0.010). After correction for the population effects of age and sex, standardized mortality ratio was shown to be higher in younger patients. The results of the present study confirm that age at disease onset is associated with differences in clinical presentation and outcome in SSc patients.

Abstract
A 77-year-old female, who suffered from rheumatoid arthritis and hypothyroidism, developed severe muscle weakness. Clinical features, blood results and muscle biopsy suggested a possible diagnosis of dermatomyositis. A computed tomography of the chest, abdomen and pelvis showed a solid mass in the left kidney. She underwent a left laparoscopic nephrectomy and histology confirmed conventional (clear cell) renal cell carcinoma. She recovered slowly and almost back to normal life after 6 months. Early appreciation of the typical skin rash may provide a clue to the diagnosis and screening for neoplasm may improve prognosis.

Abstract
INTRODUCTION The aims of this present study were firstly to assess the outcome, including functional course, in anti-Jo1 positive patients with antisynthetase syndrome (ASS), and secondly to determine predictive parameters of poor outcome in these patients. METHODS The medical records of 86 consecutive anti-Jo1 patients with ASS were reviewed in 4 academic centers. RESULTS 13 patients (15.1%) achieved remission of ASS, whereas 55 (63.9%) improved and 18 (20.9%) deteriorated in their clinical status. Both steroid and cytotoxic drugs could be discontinued in only 4.7% of patients. ASS was associated with decreased quality of life at long-term follow-up: only 69.2% of patients considered to be in remission experienced a return to previous normal activities; and 24.7% of other patients with non-remitting ASS still had a marked reduction of activities (as shown by the disability scale of the Health Assessment Questionnaire). Decreased quality of life was further due to calcinosis cutis (8.1%) and adverse effects of steroid therapy (36%). Factors associated with ASS deterioration were older age, pulmonary and esophageal involvement, calcinosis cutis and cancer. Higher anti-Jo1 levels were further associated with disease severity in ASS patients. CONCLUSIONS The present study shows high morbidity related to ASS. Furthermore, we suggest that patients with predictive factors of ASS deterioration may require more aggressive therapy. Our findings also suggest that in anti-Jo1 patients with severe esophageal manifestations, combined high dose steroids and intravenous immunoglobulins might be proposed as the first line therapy. Finally, as cancer occurred in 14% of anti-Jo1 patients, our findings underscore that the search for cancer should be performed in these patients.

Abstract
The detection and characterization of a large array of autoantibodies, including at least 8 different antisynthetase, anti-SRP, -200/100 (HMGCR), -Mi-2, -CADM-140 (MDA5), -SAE, -p155, -MJ (NXP-2), and -PMS1, frequently associated with distinct and well-defined clinicopathological features, allowed for significant improvement in the definition and diagnosis of idiopathic inflammatory myopathies (IIM). Classification remains difficult, with lingering divergence between the different specialties involved in IIM care, but several categories clearly stand out, including dermatomyositis (DM), overlap myositis (OM), polymyositis, necrotizing myositis, and sporadic inclusion body myositis (s-IBM). Biopsy and histological analysis remain crucial, particularly in the absence of autoantibodies, to accurately specify the diagnosis and rule out mimics such as muscular dystrophies and metabolic myopathies. Numerous infectious agents (in particular human immunodeficiency virus and human T cell lymphotrophic virus-1) and drugs (statins, tumor necrosis factor inhibitors, and proton pump inhibitors) can cause mimic IIM that must also be excluded. Pharmacological treatment, in addition to glucocorticoids and immunoglobulins, now includes mycophenolate mofetil and rituximab, which proved helpful in resistant cases, particularly rituximab in DM and OM. Exercise, initially seen as potentially deleterious, recently was shown to be efficacious and safe. IIM can thus be reasonably well controlled in most cases, although aggressive disease remains refractory to treatment, including some cases of necrotizing myopathy. Sporadic IBM still seems resistant to all medications tested to date.

Clinical features of inflammatory myopathies and their association with malignancy: a systematic review in asian population. ISRN RHEUMATOLOGY 2013; 2013:509354.

Abstract
Introduction. Idiopathic inflammatory myopathies (IIMs) are a group of chronic systemic autoimmune diseases that mainly affect the skeletal muscle. The common subtypes include adult dermatomyositis (DM), polymyositis (PM), and inclusion body myositis (IBM). Most of the earlier studies that described the clinical characteristics of IIM as well as their association with cancer were conducted in Western population. Our study is the first systematic review that summarizes the clinical data of DM/PM in Asian population. Methods. We identified 14 case series of DM/PM that met our eligibility criteria. We then compared this data with that from previous reports from Europe and North America. Results. Our systematic review included 2518 patients. Dermatomyositis is more common, with the ratio of dermatomyositis to polymyositis being 1.36 : 1. 69% of them were females with mean age of 45.5 years. Extramuscular manifestations, including arthritis/arthralgia, dysphagia, and interstitial lung disease, are found in one-third of the patients. Malignancy was found in 10% of patients, with lung and nasopharyngeal carcinomas being the most common malignancies associated with these myopathies. Conclusion. Clinical presentation of PM/DM appears to be similar in both Western and Asian populations. However, the type of associated malignancies in Asians differs from that in Caucasians. Ethnic background should be one of the factors that clinicians should consider while screening for malignancy.

Abstract
The idiopathic inflammatory myopathies are a group of rare disorders including polymyositis (PM), dermatomyositis (DM), and autoimmune necrotizing myopathies (NMs). The idiopathic inflammatory myopathies share many similarities. They present acutely, subacutely, or chronically with marked proximal and symmetric muscle weakness, except for associated distal and asymmetric weakness in inclusion body myositis. The idiopathic inflammatory myopathies also share a variable degree of creatine kinase (CK) elevation and a nonspecifically abnormal electromyogram demonstrating an irritative myopathy. The muscle pathology demonstrates inflammatory exudates of variable distribution within the muscle fascicle. Despite these similarities, the idiopathic inflammatory myopathies are a heterogeneous group. The overlap syndrome (OS) refers to the association of PM, DM, or NM with connective tissue disease, such as scleroderma or systemic lupus erythematosus. In addition to elevated antinuclear antibodies (ANA), patients with OS may be weaker in the proximal arms than the legs mimicking the pattern seen in some muscular dystrophies. In this review, we focus on DM, PM, and NM and examine current and promising therapies.

Abstract
OBJECTIVE To clarify those clinical characteristics dependent on patient age at onset of Japanese systemic sclerosis (SSc). METHODS A total of 329 SSc patients treated at Kanazawa University Hospital were enrolled in the study and subsequently categorized into four subgroups depending on age at SSc onset: childhood-onset, young-onset, normal age-onset, and late-onset. The clinical features at the first visit were compared between groups. Factors that correlated with age at onset were also analyzed. RESULTS The childhood-onset subgroup was characterized by a higher male:female ratio, higher anti-topoisomerase I antibody (Ab) and anti-U3 RNP Ab levels, a higher frequency of pitting scars, and a lower frequency of anticentromere Ab and interstitial lung disease (ILD). The young-onset patients had an increased frequency of anti-U1 RNP Ab and anti-U3 RNP Ab, overlap with other connective tissue diseases, digital ulcers, and pitting scars and a reduced frequency of anticentromere Ab. Patients with late-onset SSc showed a shorter disease duration and an increased frequency of anti-RNA polymerase Ab. Multiple regression analysis showed that anti-topoisomerase I Ab, anti-U1 RNP Ab, pitting scars, and long disease duration were associated with onset at a younger age, whereas anticentromere Ab and ILD were associated with onset at an older age. CONCLUSIONS The clinical phenotype of SSc in Japanese patients showed a tendency to be dependent on age at onset.

Abstract
Before the use of corticosteroids, the prognosis for polymyositis/dermatomyositis (PM/DM) was extremely poor. To date, although overall prognosis appears to be better, PM and DM are still considered to be associated with increased morbidity, primarily related to severe muscle weakness and visceral involvement. Recent series underline that only 20% to 40% of treated patients will achieve PM/DM remission, whereas 60% to 80% will experience a polycyclic or chronic, continuous course of the disease. PM/DM further continues to have a great impact on life in medium- and long-term follow-up, as up to 80% of treated patients are still disabled (using Health Assessment Questionnaire scores). The overall mortality ratio in PM/DM patients also remains threefold higher compared with the general population, with cancer, lung, and cardiac complications and infections being the most common causes of deaths. Predictive factors for a poor prognosis in PM/DM patients are older age, involvement of lung and cardiac systems, dysphagia, cancer, and serum myositis-specific antibodies (including coexistent presence of anti-Ro52 and anti-Jo1 antibodies, anti-signal recognition particle antibody, anti-155/140, and anti-CADM-140 antibodies).

Abstract
BACKGROUND AND OBJECTIVE Polymyositis (PM) and dermatomyositis (DM) are idiopathic inflammatory myopathies that are associated with a variety of clinical manifestations including pulmonary complications. The objective of the present study was to determine the causes of deaths in this complex patient population. METHODS A computer-assisted search of medical and autopsy records identified a total of 39 patients with either PM or DM who underwent an autopsy at the Mayo Clinic (Rochester, MN, USA) over a 29-year period from 1 January 1981 to 31 December 2009. The immediate causes of death along with contributing causes were determined by reviewing all available clinical data and autopsy findings. We also analysed the discordance between ante-mortem clinical diagnoses provided by clinicians and the final diagnosis by the post-mortem analysis. RESULTS Respiratory (33%), infectious (28%) and cardiovascular diseases (26%) accounted for the majority of immediate causes of death. Acute exacerbation of chronic interstitial lung disease (15%) and bronchopneumonia (15%) were the most common specific causes. Immediate cause of death was not suspected in nearly one third of cases and included bronchopneumonia, sepsis, acute myocardial infarction, aspiration pneumonia, pulmonary embolism, aortic stenosis, mycotic aneurysm rupture and acute haemoperitoneum. CONCLUSIONS We conclude that pulmonary injury is the immediate cause of death in one third of patients with PM/DM; acute exacerbation of chronic interstitial lung disease and bronchopneumonia were the most common specific causes. Immediate cause of death was not established ante-mortem in nearly one third of cases, and some of these causes were treatable.
