Abstract
INTRODUCTION Dermatomyositis (DM) is a rare systemic autoimmune disease characterized by a distinctive debilitating skin rash and skeletal muscle weakness. It is unclear if existing clinical outcome assessment (COA) measures include the concepts of priority to patients and those necessary to fully capture improvements in the active cutaneous manifestations of DM. This study aimed to develop the Cutaneous Dermatomyositis Investigator Global Assessment (CDM-IGA), a de novo IGA, for use in clinical trials of adult DM. METHODS Eight DM clinical experts participated in 60-min qualitative interviews consisting of concept elicitation and cognitive debriefing methodologies. Concept elicitation comprised open-ended questions with follow-up probes to explore clinicians' experiences of treating patients with DM, the impact of symptoms on patients' quality of life, and the severity levels of disease characteristics to explore DM progression. Cognitive debriefing required the clinical experts to perform a review of the CDM-IGA, designed to assess the severity of cutaneous disease activity of DM. After the interviews, a consensus meeting with three clinical experts was held to agree on any outstanding issues relating to the CDM-IGA. RESULTS The CDM-IGA was iteratively developed using the opinions of nine clinical experts. Feedback provided by all clinicians agreed that erythema was the main active cutaneous manifestation of DM and should be the primary characteristic on the CDM-IGA, split by erythema color and extent. To determine cutaneous disease severity, experts suggested adding a metric called secondary changes, which combined erosion/ulceration and lichenification, which could modify the patient's final score. Three clinical experts suggested that a photo-guide to support assessments of erythema across different skin tones could be beneficial. CONCLUSIONS A novel CDM-IGA was developed for use with adult patients with DM in clinical trials, based on an iterative development process that combined qualitative feedback from clinical experts of DM and importantly adult patients living with DM.

Abstract
Dermatomyositis represents an autoimmune disorder characterized by notable skin and muscular manifestations. The annual incidence of dermatomyositis stands at approximately (5~10)/1 million individuals. Notably, patients with malignant tumors exhibit an elevated risk of developing dermatomyositis compared to the general population. However, in cases where dermatomyositis co-occurs with malignancy, the efficacy of hormone therapy alone tends to be suboptimal. Moreover, reports addressing the correlation between tumor treatment and the management of dermatomyositis are scarce. A 60-year-old male patient presented with dermatomyositis, initially manifesting through symptoms such as rash, muscle weakness, and dysphagia. Despite undergoing standard hormone therapy, there was no discernible improvement in the dermatomyositis symptoms. Considering the patient's concomitant troublesome cough, further investigations were conducted, including CT, PET-CT, and pathological biopsy. These assessments confirmed the diagnosis of limited-stage small cell lung cancer (T1cN3M0 IIIB). Notably, in this patient, dermatomyositis was suspected to be a paraneoplastic syndrome associated with small cell lung cancer. Standard chemotherapy and radiotherapy were employed to treat the small cell lung cancer, resulting in partial remission after two treatment cycles. As the malignancy regressed, a notable improvement in dermatomyositis symptoms was observed, subsequently leading to a gradual reduction in the prescribed hormone dosage. In conclusion, we present a comprehensive case study of dermatomyositis as a paraneoplastic syndrome throughout the treatment process. The response to tumor therapy coincided with the amelioration of dermatomyositis symptoms. Therefore, diligent malignancy screening is imperative for patients diagnosed with dermatomyositis.

Abstract
Dermatomyositis (DM) is an autoimmune disorder, which belongs to a group of rare autoimmune dermatoses characterized by different skin features and variable muscle involvement. We recognize four main variants of DM: classic DM, clinically amyopathic DM, paraneoplastic DM, and juvenile DM. Clinically, patients show several skin features, but heliotrope rash, and violaceous papules located at the interphalangeal or metacarpophalangeal joints (Gottron's papules) are the most frequently observed. Together with skin features, patients show muscle involvement, most commonly with symmetrical weakness of the proximal muscles. DM belongs to the facultative paraneoplastic dermatoses and a wide range of solid or hematologic malignancies can be detected in DM patients. Serologically, a wide range of autoantibodies can be detected in patients with DM. Indeed, distinct serotypes can be related to specific phenotypes with specific clinical features, carrying a different risk for systemic involvement and for malignancies. Systemic corticosteroids are still considered the first-line approach, but several steroid-sparing agents, such as methotrexate, azathioprine or mycophenolate mofetil, have been reported as effective in treating DM. Furthermore, new class of drugs, such as monoclonal antibodies, purified immunoglobulins or Janus kinase inhibitors are becoming more relevant in the clinical practice or are currently under investigation. In this work, we aim to offer a clinical overview of the diagnostic workout, the characteristics of DM variants, the role of autoantibodies in DM, and the management of this life-threatening systemic disorder.

Abstract
INTRODUCTION Dermatomyositis is a rare autoimmune inflammatory condition affecting skin and muscles. The disease can be seen in both adults and children. It can be associated with malignancy. Considering involvement of skin in the disease, many patients consult dermatologists for its treatment. Hence, knowledge about its presentation, complications, prognosis, and treatment is necessary. OBJECTIVE The objective of this review article is to provide comprehensive information about treatment of dermatomyositis. METHODS In this review article, we reviewed the published literature on adult and juvenile dermatomyositis to highlight the treatment. Articles published in peer-reviewed journals including reviews, clinical trials, case series, and case reports published in electronic database (MEDLINE/PubMed) through January 2021, cross references of respective articles and trials from clinicaltrials.gov were included for qualitative analysis of the literature. RESULTS Treatment options for dermatomyositis include traditional immunosuppressive agents and immunomodulatory therapy. High-dose corticosteroids represent the first line of treatment while other immunosuppressive agents are also used, either in combination with or as an alternative to corticosteroids, after initial treatment failure. Some biological agents have been used for the treatment of dermatomyositis with variable responses. CONCLUSION Although several treatment options are available, several questions remain unanswered about the optimal treatment of dermatomyositis.

Abstract
Dermatomyositis (DM) is a rare inflammatory myopathy with an incidence of 9.63 per 1 000 000 people and typically presents with skin rash and muscle weakness. We report a case of DM that presented with proximal muscle weakness, normal creatine phosphokinase (CPK), negative myositis antibody panel, and non-specific histopathological findings on muscle biopsy, without initial skin involvement. A 67-year-old male presented with subacute bilateral proximal lower-extremity weakness and weight loss of 20 pounds over 3 months. Laboratory investigation was significant for elevated erythrocyte sedimentation rate, C-reactive protein, CPK, and aldolase, with negative myositis-specific antibodies. Femur magnetic resonance imaging revealed subcutaneous, fascial, and muscle edema throughout quadriceps and gluteal muscles. Muscle biopsy showed myofiber atrophy with perivascular and endomysial T-lymphocytes and histiocytes, as well as scattered necrotic myofibers. He was diagnosed with inflammatory myositis and started on prednisone and monthly IVIG infusions. At 2-month follow-up, he reported new rashes on the extensor surfaces of the hands consistent with Gottron's papules, mechanic's hands, and livedo reticularis of feet and arms. Cases of DM that present with myopathy and later develop skin changes are rare. Our patient had several months of progressive proximal muscle weakness, and skin changes occurred after he was started on treatment. Laboratory findings include elevated CPK, aldolase, and myositis-specific auto-antibodies. Muscle biopsy helps in diagnosis; however, findings may be nonspecific-as was the case in our patient. Corticosteroids are first-line treatment. Long-term follow-up studies are necessary to better understand the incidence of late-onset development of typical skin findings.

Abstract
Dermatomyositis is a rare inflammatory myopathy that is often related to lung cancer. In this retrospective observational study, we analyzed data from patients diagnosed with lung cancer at Soroka University Medical Center between January 2017 and July 2021. A total of 689 patients with lung cancer were included in this study, 97 of whom had small cell lung cancer and 592 had non-small cell lung cancer. We identified a single patient (60-year-old female) who presented with signs and symptoms of dermatomyositis, which was later confirmed to be associated with lung cancer as a paraneoplastic syndrome. Both our study and a recent review of the literature illustrate the temporal link between dermatomyositis and lung cancer, as well as reinforce the need for heightened cancer screenings in DM patients.

Abstract
Dermatomyositis (DM) and polymyositis (PM) are idiopathic inflammatory myopathies characterized by progressive, symmetric, mainly proximal muscle weakness. DM is also characterized by cutaneous involvement. However, other clinical features, systemic involvement, histopathological findings, response to treatment, and prognosis, differ significantly. Although uncommon, ocular manifestations in DM and PM may potentially affect any structure within the eye. Notwithstanding being generally mild, ocular involvement in DM and PM may result in significant morbidity. Left untreated, significant retinal inflammation associated with hemorrhage and detachment may occur, leading to significant vision loss. This review aims to present an up-to-date overview for rheumatologists about the ocular involvement and potential complications of DM and PM and when to refer to the ophthalmologist to avoid sight-threatening complications.

Abstract
INTRODUCTION/OBJECTIVES Rituximab (RTX) is a treatment for refractory inflammatory myopathies, such as dermatomyositis (DM) and polymyositis (PM). This study describes the characteristics of patients receiving RTX for myositis in our institution to evaluate its efficacy. METHOD We collected demographic data from all patients diagnosed with DM or PM who received RTX between 2011 and 2018. Clinical and serological variables (including creatine phosphokinase [CPK] levels) were analyzed. Remission of disease was defined as no evidence of disease activity (active myositis) for longer than a 6-month continuous period while undergoing myositis therapy or no medication. RESULTS Eighteen patients who had received first-line immunosuppressants were included. Fifteen (83%) had DM, 2 (11%) had PM, 1 had juvenile dermatomyositis, and 14 (77%) were women. All patients received glucocorticoids. Three patients (16.6%) were treated with RTX as monotherapy, and 15 (83.3%) were treated with RTX combined with other immunosuppressants. On average, there were 2 RTX treatment cycles. Improved muscular weakness was found in 13 cases (72%), and improved serum CPK levels were found in 15 cases (83%). Twelve patients (66%) achieved remission. CONCLUSIONS Most patients experienced an objective improvement, as reflected in their serum CPK values and degree of muscular weakness. This suggests that RTX could be helpful in treating refractory myositis.

Abstract
Dermatomyositis (DM) is an autoimmune condition characterized by skin rashes and progressive muscle weakness. It is classified under the idiopathic inflammatory myopathies (IIM) and can affect children as well as adults. A heightened incidence of malignancy in adults with DM has laid greater focus on its early diagnosis, treatment, and monitoring. In recent years, a greater understanding of the pathogenesis of the disease, its diagnostic criteria and management has improved the quality of life in affected individuals. The orofacial region presents with many manifestations of the disorder, sometimes even the initial presenting signs. This review presents an update on the disease process, its pathogenesis, diagnostic criteria, orofacial manifestations, medical management and dental considerations for patients with DM. The updated knowledge about DM is crucial for oral health care providers to plan and execute oral health care in a coordinated manner.

Abstract
Dermatomyositis (DM) is an idiopathic inflammatory myopathy that is closely related to malignant diseases. Our study aims to investigate the incidence and predictive factors for occurrence of malignancy among DM patients from Central China.We performed a retrospective, paired, case-control study of 736 DM patients admitted to the First Affiliated Hospital of Zhengzhou University between 2010 and 2017. We paired the 65 patients with malignancy with age-matched and sex-matched patients without malignancy in a ratio of 1:2. Two hundred two patients were finally enrolled and their clinical and laboratory data were collected.The incidence of malignancy in DM patients was 8.83% (65/736). Most malignancies were detected in the most recent 1 year before (9/65, 13.85%) or within 3 years after (40/65, 61.54%) the onset of DM. Males (35/65, 53.85%) and patients aged between 50 and 69 years (43/65, 66.15%) were prone to develop malignancies. Lung cancer (n = 11, 31.43%) was the most common malignancy in male patients, while for females, thyroid, breast and cervical cancer (n = 4 each, 13.33%) were more prevalent. Adenocarcinoma and squamous cell carcinoma (both 18/65, 27.69%) were the top two most common pathological types. Univariate analysis demonstrated that Gottron's sign (P = .02), dysphagia (P = .04), albumin (ALB) reduction (P = .003), aspartate aminotransferase (AST, P = .03), creatine kinase-MB (P = .02), absence of fever (P = .02), arthralgia (P = .04) and interstitial lung disease (ILD, P = .05) were closely related to the occurrence of malignancy. Multivariate analysis revealed the independent risk factors of ALB reduction (odds ratio = 1.546, P = .04) and the protective factor of ILD (odds ratio = 0.349, P = .003). There was no significant difference in the follow-up period between patients with and without ILD (P = .38).ALB reduction and the absence of ILD were the risk factors for malignancy in DM patients. The protective mechanism of ILD for DM patients needs further study.

Abstract
PURPOSE OF THE REVIEW Dermatomyositis (DM) is an uncommon autoimmune disease that primarily affects the skin, muscle, and/or lungs, and remains a therapeutic challenge. We discuss recent studies evaluating efficacy of conventional treatments for clinically amyopathic DM (CADM), DM-associated interstitial lung (ILD) disease, and classic DM (CDM). We highlight several emerging new therapies with a focus on clinical trials, systematic reviews, and case series in the last 5 years. RECENT FINDINGS Recent studies report a significant number of patients remain refractory to antimalarials and require second- and third-line agents. Effective treatment for DM-associated ILD can vary based on patient specific antibodies. CDM requires oral glucocorticoids; recent studies have evaluated the benefits of adjunctive therapies including methotrexate and calcineurin inhibitors. New therapies target cell populations or cytokines thought to drive disease pathogenesis. Dermatomyositis is an autoimmune disease that remains challenging to treat. Many patients are refractory to conventional therapies, warranting the development and evaluation of new treatments.

Abstract
The second article in this continuing medical education series reviews the initial evaluation of patients with suspected dermatomyositis (DM), the relevant work-up for malignancy and interstitial lung disease once a diagnosis of DM is made, and treatment recommendations for patients with DM based on disease severity, the presence of systemic symptoms, and myositis-specific antibody (MSA) profiles. This review emphasizes the emerging role of MSAs in the diagnosis of DM and highlights how MSAs can be used to guide the appropriate work-up for malignancy and interstitial lung disease. The treatment approach proposed by this continuing medical education series discusses both established and novel therapies for DM and highlights the importance of considering lesion type, degree of muscle involvement, presence of systemic symptoms, presence of MSAs, and patient age when determining the best treatment approach for a patient with DM.
