Abstract
Idiopathic inflammatory myopathies are a group of autoimmune diseases with a broad spectrum of clinical presentations, primarily characterised by immune-mediated muscle injury. Until recently, there was little insight into the pathogenesis of idiopathic inflammatory myopathies, which challenged the recognition of the breadth of heterogeneity of this group of diseases as well as the development of new therapeutics. However, the landscape of idiopathic inflammatory myopathies is evolving. In the past decade, advances in diagnostic tools have facilitated an enhanced understanding of the underlying disease mechanisms in idiopathic inflammatory myopathies, enabling the expansion of therapeutic trials. The fields of transcriptomics, prot§eomics, and machine learning offer the potential to gain greater insights into the underlying pathophysiology of idiopathic inflammatory myopathies. Harnessing insights gained from these sophisticated tools could contribute to the identification of differences at a molecular level among patients, accelerating the development of targeted, tailored therapies. Bolstered by the validation and standardisation of robust outcome measures, many promising therapies are in clinical trial development. Although challenges remain, there is great optimism in the field due to the progress in innovative diagnostics, outcome measures, and therapeutic approaches. In this Review, we discuss the expanding landscape of idiopathic inflammatory myopathies as the frontier of precision medicine becomes imminent.

Abstract
PURPOSE OF REVIEW Systemic sclerosis associated myopathy (SSc-AM) is a complex, heterogenous disease that is associated with poor outcomes. SSc-AM lacks a clear definition, and continues to be poorly recognized. The purpose of this review is to provide a contemporary overview of the clinical, serological and pathophysiologic findings in SSc-AM to guide optimal recognition and management of this challenging disease manifestation. RECENT FINDINGS There have been several advances in diagnostic techniques to facilitate characterization of SSc-AM, including muscle MRI, in which findings were correlated to distinct histopathologic categories of muscle involvement in SSc, histopathologic findings of prominent fibrosis or inflammation on biopsy, and the identification of novel autoantibodies associated with SSc-AM, which may be associated with distinct clinical phenotypes. In one of the largest studies to date, 17% of a well phenotyped SSc cohort were found to have myopathy, which was an independent risk of death, even after adjusting for potential confounders, further highlighting the importance of timely recognistion and management of SSc-AM. SUMMARY There is increasing recognition of the importance of SSc-AM. Novel diagnostic tools provide the opportunity for more detailed insights into pathophysiologic mechanisms, which may facilitate the development of a rigorous consensus definition of SSc-AM.

Abstract
INTRODUCTION Idiopathic inflammatory myopathies (IIMs) represent a diverse group of systemic autoimmune disorders with variable clinical manifestations and disease course. Currently, the challenges of IIMs are multifold, including difficulties in timely diagnosis owing to clinical heterogeneity, limited insights into disease pathogenesis, as well as a restricted number of available therapies. However, advances utilizing myositis-specific autoantibodies have facilitated the definition of subgroups as well as the prediction of clinical phenotypes, disease course, and response to treatment. AREAS COVERED Herein we provide an overview of the clinical presentations of dermatomyositis, anti-synthetase syndrome, immune-mediated necrotizing myopathy, and inclusion body myositis. We then provide an updated review of available and promising therapies for each of these disease groups. We synthesize current treatment recommendations in the context of case-based construct to facilitate application to patient care. Finally, we provide high-yield, clinical pearls relevant to each of the subgroups that can be incorporated into clinical reasoning. EXPERT OPINION There are many exciting developments on the horizon for IIM. As insights into pathogenesis evolve, the therapeutic armamentarium is expanding with many novel therapies in development, holding promise for more targeted treatment approaches.

Abstract
Background Idiopathic inflammatory myopathies (IIM) are a rare heterogeneous group of diseases characterised by chronic skeletal muscle inflammation, but other organs are also frequently involved. IMM represent a diagnostic challenge and a multidisciplinary approach is important to ensure successful diagnosis and adequate follow-up of these patients. Objective To describe the general functioning of our multidisciplinary myositis clinic, highlighting the benefits of multidisciplinary team management in patients with confirmed or suspected IIM and to characterise our clinical experience. Methods Description of the organization of a dedicated multidisciplinary myositis outpatient clinic, supported by IMM specific electronic assessment tools and protocols based on our Portuguese Register - Reuma.pt. In addition, an overview of our activity between 2017 and 2022 is provided. Results An IIM multidisciplinary care clinic, based on a close collaboration between Rheumatologists, Dermatologists and Physiatrist is detailed in this paper. One hundred and eighty-five patients were assessed in our myositis clinic; 138 (75%) of those were female, with a median age of 58 [45-70] years. At the last appointment, 130 patients had a confirmed IIM diagnosis, and the mean disease duration was 4 [2-6] years. The most frequent diagnosis was dermatomyositis (n = 34, 26.2%), followed by antisynthetase syndrome (n = 27, 20.8%) and clinically amyopathic/paucimyopathic dermatomyositis (n = 18, 13.8%). Twenty-four patients (18.5%) were on monotherapy and 94 (72.3%) were on combination therapy. Conclusion A multidisciplinary approach is important to ensure the correct diagnosis and follow-up of these patients. A myositis clinic, with a standardised practice at a tertiary hospital level, contributes to a standardization of care and opens research opportunities.

Abstract
Dermatomyositis (DM) is an idiopathic inflammatory myopathy most commonly characterized by proximal, progressive, symmetrical muscle weakness, as well as specific dermatological manifestations. The presence of nuclear matrix protein 2 (NXP-2) autoantibodies is predominantly associated with joint contractures and calcinosis. A 19-year-old female was diagnosed with DM with positive anti-NXP-2 autoantibodies. She had severe joint involvement of the shoulders, elbows, wrists, and ankles, and the presence of calcinosis was documented on radiographs. Concomitantly, she presented with heliotrope erythema on the eyelids and Grotton's papules on the interphalangeal joints of the hands. After performing a diagnostic investigation and beginning targeted therapy, the patient was transferred to an inpatient Physical Medicine and Rehabilitation Department to carry out a rehabilitation program. The patient had a favorable outcome, with improved range of motion and muscle strength, with a Manual Muscle Testing 8 at the time of admission of 73/150, and at discharge from the hospital of 94/150. Regarding the functional scales, she had a Functional Independence Measure at the time of admission of 87/126 and a Barthel Index of 50/100, with an objective improvement at the time of discharge to 118/126 and 90/100, respectively. DM is an insidious chronic disease with multisystemic involvement and can lead to a great loss of independence. Most patients with DM do not recover their previous muscle function, which leads to a negative impact on their quality of life. The institution of an early rehabilitation program seems to have beneficial effects on the functionality and independence of these patients. Its treatment is based on a multidisciplinary approach, and the established rehabilitation program must be individualized and directed to the deficits and limitations of each patient.

Abstract
The recent global increase in popularity of home-based yoga, an ancient Indian technique practiced for thousands of years, has translated into its use as a complementary therapy for a multitude of ailments. This review aims to examine the published literature regarding the effects of yoga therapy on systemic chronic diseases; in particular on the inflammatory myopathies (IMs) and other muscle disorders. Despite the fact that the evidence base for yoga in inflammatory myositis is in its infancy, collateral results in other disorders such as muscular dystrophies are promising. A beneficial effect of yoga in chronic pain has been shown alongside an improvement in motor function and muscle strength. Patients with Duchenne muscular dystrophy with respiratory involvement may find improvement in lung function. Elderly patients may experience reduction in falls secondary to an improvement in balance while practicing long-term yoga therapy. Further benefits are improving disorders of mental health such as depression and anxiety. A reported improvement in overall quality of life further suggests its efficacy in reducing morbidity in patients with chronic diseases, who often suffer co-existent psychological comorbidities.

Abstract
Trials regarding physical exercise in dermatomyositis (DM) and polymyositis (PM) are heterogeneous. We aimed to summarize and critically analyze the available evidence to support the hypothesis that exercise is safe and improves strength and aerobic capacity. We performed a systematic review of clinical trials regarding physical exercise in dermatomyositis and polymyositis, without time restriction. We included studies from MEDLINE, EMBASE, SciELO, and Web of Science, published in English, Portuguese, or Spanish, and reporting outcomes related to safety, muscle performance, or aerobic capacity. The certainty of evidence was evaluated in accordance with the GRADE methodology. Meta-analysis was carried using pooled standardized mean differences (SMD) with 95% confidence interval as effect measure. We included 19 studies and 298 patients. The certainty of evidence was downgraded due to unbalanced confounding variables. The meta-analysis demonstrated improvements in strength (SMD [95% CI] = 0.61 [0.37-0.85], P < .00001) and aerobic capacity (SMD [95% CI] = 0.82 [0.29-1.34], P = .002), with no difference in creatine phosphokinase levels (SMD [95% CI] = - 0.23 [- 0.5-0.03], P = .08) after the interventions. No exacerbation was reported, and results were favorable in all stages of disease and ages, but might be different in the future with new classification criteria for PM and the inclusion of other idiopathic inflammatory myopathies. Novel approaches such as blood flow restriction training and aquatic plyometric exercises were promising. Physical exercise in DM/PM patients of all ages is probably safe and moderately improves muscle strength and aerobic capacity.

Abstract
OBJECTIVES To date, there is almost no information concerning the sexual health of patients with idiopathic inflammatory myopathies (IIM). This cross-sectional study aimed to compare sexual function in patients with IIM to age-/sex-matched healthy controls (HC) and determine the potential impact of clinical features on sexual function. METHODS In total, 122 women (61 with IIM, 61 age-matched HC) and 22 men (11 with IIM, 11 age-matched HC) aged 18-80 years completed gender-specific selection of 7 well-established and validated questionnaires assessing sexual health and function (Female Sexual Function Index, Brief Index of Sexual Function for Women, Sexual Function Questionnaire, Sexual Quality of Life Questionnaire-Female, International Index of Erectile Function, Male Sexual Health Questionnaire, Sexual Quality of Life Questionnaire-Male). Results were compared between patients and HC and correlated with selected disease-related features. RESULTS The prevalence of sexual dysfunction in IIM was 59% in women (vs 40% in HC), and 64% (vs 9% in HC) in men. Men and women with IIM reported significantly impaired sexual function compared with sex-/age-matched HC. Decreased sexual function was associated with muscle weakness, disability, physical inactivity, fatigue, depression and decreased quality of life. CONCLUSIONS Our results suggest that sexual dysfunction is common among IIM patients and more attention should be paid to this aspect of the disease.

Abstract
PURPOSE OF REVIEW The aim of this review is to present the main pieces of evidence, recent literature and to present future perspectives on the use of exercise/physical training in the treatment and improvement of the quality of life of patients with systemic autoimmune myopathies. RECENT FINDINGS In the last decades, knowledge about the relevance of physical exercise training in preventing and treating chronic diseases and improving quality of life has grown. Following the global trend exemplified by the expression 'exercise is medicine', the importance of exercise/physical training has also grown in myopathies. However, the science of exercise has a lot to collaborate on and improve patients' quality of life with myopathies by appropriating new technological tools, including accessible and low-cost devices and smartphone apps. SUMMARY Physical exercise, as already consolidated in the literature, is an effective, well tolerated, and low-cost strategy for patients with myopathies. The use of wearable devices, smartphone apps, and online training prescriptions must accompany the global scenario, bringing new research fields and expanding the options for access to training for the individualized basis, and prescribed by qualified professionals.

Abstract
Idiopathic inflammatory myopathies (IIM) are rare diseases affecting skeletal muscles and leading to progressive muscle weakness and disability. Thanks to the better understanding of their pathogenesis, the management of IIM has been noteworthily implemented in recent years. Current therapeutic strategies include pharmacological and non-pharmacological interventions, among which physical exercise represents a useful option, able to ameliorate disease activity without worsening muscle inflammation. The aim of this narrative review is therefore to provide an updated overview of the benefits of physical exercise in patients with IIM and to suggest plausible training programs to be applied in patients with dermatomyositis, polymyositis, necrotizing myopathy, and inclusion body myositis. In this regard, a combined strategy mixing aerobic and resistance exercises could positively affect the pro-inflammatory and metabolic pathways occurring in skeletal muscles, while promoting muscle fiber regeneration and repair.

Abstract
BACKGROUND The structural and functional changes of the skeletal muscles in idiopathic inflammatory myopathies (IIM) caused by inflammation and immune changes can be severely disabling. The objective of this study was to assess the effect of a 24-week program combining a supervised training of activities of daily living (ADL), resistance, and stability with home exercise for improving muscle function, compared to a daily home-based exercise representing the regular outpatient care. METHODS Fifty-seven patients with IIM were consecutively and non-selectively enrolled in an intervention (IG, n = 30) or control (CG, n = 27) group. Both groups were provided a standard-of-care pharmacological treatment and follow-up. Only the IG underwent the supervised intervention twice a week for 1 h per session. At baseline, 12, 24, and 48 weeks, all patients were assessed by an assessor blinded to the intervention for primary outcomes: muscle strength (Manual Muscle Testing of eight muscle groups [MMT-8]) and endurance (Functional Index-2 [FI-2]), and secondary outcomes: stability and body composition. Secondary outcomes also included questionnaires evaluating disability (Health Assessment Questionnaire [HAQ]), quality of life (Short Form 36 [SF-36]), depression (Beck's Depression Inventory-II [BDI-II]), and fatigue (Fatigue Impact Scale [FIS]), and analysis of the systemic and local inflammatory response and perceived exertion to assess the safety of the intervention. RESULTS Twenty-seven patients in the IG and 23 in the CG completed the entire program and follow-up. At week 24, compared to deterioration in the CG, we found a significant improvement in the IG in muscle strength (mean % improvement compared to baseline by 26%), endurance (135%), disability (39%), depression (26%), stability (11%), and basal metabolism (2%) and a stabilization of fitness for physical exercise. The improvement was clinically meaningful (a 24-week change by >20%) in most outcomes in a substantial proportion of patients. Although the improvement was still present at 48 weeks, the effect was not sustained during follow-up. No significant increase in the systemic or local expression of inflammatory markers was found throughout the intervention. CONCLUSIONS This 24-week supervised intervention focused on ADL training proved to be safe and effective. It not only prevented the progressive deterioration, but also resulted in a significant improvement in muscle strength, endurance, stability, and disability, which was clinically meaningful in a substantial proportion of patients. TRIAL REGISTRATION ISRCTN35925199 (retrospectively registered on 22 May 2020).

Abstract
Background Inflammatory myopathies (IMs) are a group of rare conditions characterized by proximal and often symmetrical muscle weakness and reduced muscle endurance. The recommended medical treatment is based on corticosteroids in combination with immunosuppressants. This anti-inflammatory therapy serves to inhibit and prevent inflammation but does not influence impaired muscle strength. Exercise, particularly progressive resistance training, plays therefore an important role in IMs management. Blended therapy, a combination of face-to-face treatment and telerehabilitation, may be a powerful therapy option in improving exercise program adherence in these patients. Methods The feasibility of a 12-week interactive tablet-based home exercise program combined with face-to-face therapy sessions – a ‘blended therapy’ approach - was evaluated using a quasi-experimental one-group pre-post comparison design. Primary outcomes were recruitment, attrition and adherence rates, plus measures of acceptance (Technology Acceptance Model Questionnaire (TAM)) and satisfaction (satisfaction questionnaire). Secondary outcomes comprised potential effects of the intervention on muscle strength and function, activity limitation, disability and health-related quality of life. Results Thirteen of the included 14 participants completed the study without any related adverse events. Mean adherence to exercise program was 84% (range: 25–100%) and participants indicated high acceptance of the intervention with mean TAM scores between 6.1 and 6.5 points. Overall satisfaction with the therapy sessions, the home program, and the technology was good. Approximately half the participants wished for longer training periods and more training sessions per week. There were inconsistent effects on muscle strength, muscle function, activity limitation, disability, and health-related quality of life. Conclusion Blended therapy combining the use of an interactive tablet-based resistance training program with face-to-face therapy sessions is feasible and safe and participants` acceptance with this approach was high. Furthermore, results were obtained that might be useful in selecting appropriate assessments and sample sizes in future trials. Trial registration NCT03713151.

Abstract
RESUMO Este estudo teve por objetivo avaliar o impacto do treinamento físico sobre o desempenho físico em pacientes com dermatomiosite e polimiosite. Para tanto, uma revisão sistemática e metanálise foi conduzida de acordo com as diretrizes do PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). A pesquisa bibliográfica foi realizada nas seguintes bases de dados: PubMed/MEDLINE e Web of Science, utilizando combinações das seguintes palavras-chave em inglês: dermatomyositis OR polymyositis OR myositis AND exercise OR physical exercise OR physical therapy OR aerobic exercise OR endurance exercise OR resistance exercise. Foram incluídos estudos que atenderam aos seguintes critérios: (1) os participantes apresentavam diagnóstico de dermatomiosite ou polimiosite; (2) os pacientes foram submetidos a um protocolo de treinamento físico; (3) o desempenho físico foi mensurado antes e após o protocolo de treinamento físico. Um total de 14 artigos foram selecionados para inclusão na revisão sistemática e 10 artigos foram selecionados para inclusão na metanálise. Os resultados demonstram que o treinamento físico é eficaz em aumentar o desempenho físico global nos pacientes com dermatomiosite e polimiosite (tamanho do efeito: 0,72; IC 95% 0,55; 0,89). Além disso, foi demonstrado também que tanto as variáveis de desempenho aeróbio (tamanho do efeito: 0,88; IC 95% 0,54; 1,21), quanto as variáveis de desempenho resistido (tamanho do efeito: 0,64; IC 95% 0,43; 0,85) são beneficiadas com o treinamento físico nesses pacientes. Conclui-se que o treinamento físico apresentou um efeito benéfico significativo sobre o desempenho físico global, aeróbio e resistido em pacientes com dermatomiosite e polimiosite.

Abstract
Inflammatory myopathies are a group of immune-mediated muscle disorders comprising dermatomyositis; polymyositis; overlap myositis, including antisynthetase syndromes and nonspecific myositis, immune-mediated necrotizing myopathies, and sporadic inclusion body myositis. They are now much more eloquently classified both pathologically and clinically because of the discovery of several myositis-specific and myositis-associated antibodies. These antibodies also aid in choosing the best treatment options in each case. Based on the initial classifications of inflammatory myopathies, inclusion body myositis, overlap myositis, and necrotizing myositis were all included in the polymyositis group. This article discusses cases, diagnostic tools, associated antibodies, and pathology.

Abstract
PURPOSE OF REVIEW Dysphagia is a common symptom in inflammatory myopathies. This review provides an overview on the epidemiology, clinical impact, and management of dysphagia in myositis. Relevant diagnostic tools and treatment strategies are discussed. RECENT FINDINGS Dysphagia can occur in any inflammatory myopathy, particularly in inclusion body myositis (IBM). It can lead to malnutrition or aspiration with subsequent pneumonia or even death. Dysphagia can be explored and monitored by patient-reported outcome scales for swallowing. New diagnostic tools such as real-time MRI and oro-pharyngo-esophageal scintigraphy have been studied for assessing dysphagia. Botulinum toxin injection can alleviate dysphagia in IBM. High-dose glucocorticosteroids are considered a first-line treatment for dysphagia in all other myositis subforms. Evaluation of dysphagia in myositis requires thorough clinical workup and appropriate instrumental procedures. Treatment options are available for dysphagia, but controlled trials and consensus on best patient care are required for this important symptom.

Abstract
Because of its several advantages, ultrasound imaging has started to take place in the diagnostic and therapeutic algorithms of a wide range of musculoskeletal disorders. After the first part on traumatic conditions, in this review, the authors aim to discuss the applicability of ultrasound imaging for nontraumatic muscle disorders in the daily clinical/academic practice. While trying to summarize the whole spectrum (e.g., myofascial pain syndrome, inflammatory diseases, neuromuscular disorders), special emphasis will be given to sarcopenia, which is, by far, the most challenging clinical condition in the era of "aging world." Of note, rehabilitation with regard to the exemplified problems will also be briefed throughout.

The immune system in sporadic inclusion body myositis patients is not compromised by blood-flow restricted exercise training. Arthritis Res Ther 2019; 21:293. [PMID: 31852482 PMCID: PMC6921522 DOI: 10.1186/s13075-019-2036-2] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2019] [Accepted: 10/21/2019] [Indexed: 01/17/2023] Open
Abstract
BACKGROUND Sporadic inclusion body myositis (sIBM) is clinically characterised by progressive proximal and distal muscle weakness and impaired physical function while skeletal muscle tissue displays abnormal cellular infiltration of T cells, macrophages, and dendritic cells. Only limited knowledge exists about the effects of low-load blood flow restriction exercise in sIBM patients, and its effect on the immunological responses at the myocellular level remains unknown. The present study is the first to investigate the longitudinal effects of low-load blood flow restriction exercise on innate and adaptive immune markers in skeletal muscle from sIBM patients. METHODS Twenty-two biopsy-validated sIBM patients were randomised into either 12 weeks of low-load blood flow restriction exercise (BFRE) or no exercise (CON). Five patients from the control group completed 12 weeks of BFRE immediately following participation in the 12-week control period leading to an intervention group of 16 patients. Muscle biopsies were obtained from either the m. tibialis anterior or the m. vastus lateralis for evaluation of CD3-, CD8-, CD68-, CD206-, CD244- and FOXP3-positive cells by three-colour immunofluorescence microscopy and Visiopharm-based image analysis quantification. A linear mixed model was used for the statistical analysis. RESULTS Myocellular infiltration of CD3-/CD8+ expressing natural killer cells increased following BFRE (P < 0.05) with no changes in CON. No changes were observed for CD3+/CD8- or CD3+/CD8+ T cells in BFRE or CON. CD3+/CD244+ T cells decreased in CON, while no changes were observed in BFRE. Pronounced infiltration of M1 pro-inflammatory (CD68+/CD206-) and M2 anti-inflammatory (CD68+/CD206+) macrophages were observed at baseline; however, no longitudinal changes in macrophage content were observed for both groups. CONCLUSIONS Low-load blood flow restriction exercise elicited an upregulation in CD3-/CD8+ expressing natural killer cell content, which suggests that 12 weeks of BFRE training evokes an amplified immune response in sIBM muscle. However, the observation of no changes in macrophage or T cell infiltration in the BFRE-trained patients indicates that patients with sIBM may engage in this type of exercise with no risk of intensified inflammatory activity.

Abstract
Dysphagia in inclusion body myositis (IBM) is common and associated with increased mortality and morbidity due to aspiration pneumonia, malnutrition and dehydration. There is currently no consensus on treatment of dysphagia in IBM and outcomes are variable depending on timing of intervention, patient preference and available expertise. There is a paucity of research exploring the pathophysiology of dysphagia in IBM and appropriate investigations. Increased knowledge of the aetiopathogenesis is likely to change the approach to treatment as well as improve the quality of life for patients. This review explores the epidemiology and pathophysiology of dysphagia in IBM and the currently available treatment strategies.
