Abstract
PURPOSE Autoimmune bullous diseases, connective tissue diseases, and vasculitis represent a group of severe rare skin diseases. While glucocorticoids and immunosuppressive agents serve as standard treatments for these diseases, their efficacy is limited due to adverse side effects, indicating the need for alternative approaches. Biologics have been used in the management of some rare skin diseases. However, the use of biologics is associated with concerns, such as infection risk and high costs, prompting the quest for efficacious and cost-effective alternatives. This study discusses the safety issues associated with tofacitinib and its potential in treating rare skin diseases. METHODS This narrative review focuses on the pharmacodynamic properties of tofacitinib and its impact on the JAK/STAT pathway. In addition, we present a comprehensive discussion of the effects and mechanism of action of tofacitinib for each severe rare skin disease. RESULTS This role of tofacitinib in treating severe rare skin diseases has been discussed, shedding light on its promising prospects as a treatment modality. Few reports of serious adverse events are available in patients treated with tofacitinib. CONCLUSION We explored the mechanism of action, efficacy, and safety considerations of tofacitinib and found that it can be used as a treatment option for rare skin diseases. However, multicenter clinical studies are needed to confirm the efficacy and safety of JAK inhibitors.

Abstract
Atraumatic muscle disorders comprise a very wide range of skeletal muscle diseases, including metabolic, inflammatory, autoimmune, infectious, ischemic, and neoplastic involvement of the muscles. Therefore, one must take clinical and laboratory data into consideration to elucidate the differential diagnoses, as well as the distribution of the muscle compromise along the body-whether isolated or distributed along the body in a symmetric or asymmetrical fashion. Assessment of muscular disorders often requires imaging investigation before image-guided biopsy or more invasive procedures; therefore, radiologists should understand the advantages and limitations of imaging methods for proper lesion evaluation and be aware of the imaging features of such disorders, thus contributing to proper decision-making and good patient outcomes. In this review, we propose a systematic approach for the assessment of muscle disorders based on their main imaging presentation, dividing them into patterns that can be easily recognized.

Abstract
Dermatomyositis is an idiopathic inflammatory myopathy with cutaneous manifestations, which is associated with several types of malignancies, yet it has been rarely linked to neuroendocrine tumors (NETs). Here we report two cases of dermatomyositis associated with NETs of differing primary sites. Case 1: A 46-year-old female presented with a facial rash and proximal muscle weakness of both extremities. Investigations revealed elevated creatine kinase (CK) and positive anti-transcriptional intermediary factor 1-γ antibody (TIF1γ). The patient had been diagnosed with dermatomyositis and underwent a total body CT scan, which revealed prominent mediastinal lymphadenopathy, which a subsequent biopsy determined to be neuroendocrine carcinoma of small cell type. Treatment with high-dose corticosteroids was initiated, in addition to chemotherapy-based oncological management. Case 2: A 54-year-old female presented with a facial rash, progressive dyspnea, and general malaise. Laboratory investigations revealed positive anti-melanoma differentiation-associated gene-5 (MDA5) and positive anti-Ro antibody, with a normal level of creatine kinase (CK). A chest CT scan revealed multiple ground-glass opacities. Despite treatment with high-dose intravenous methylprednisolone, IVIG and an infusion of the anti-IL-6 sarilumab [Kevzara], the patient rapidly deteriorated and was intubated. Within days, the patient developed bowel ischemia and underwent a laparotomy which was then complicated by an invasive infection. This resulted in patient's death. Pathology results from colonic tissue demonstrated an appendiceal neuroendocrine tumor. These cases demonstrate the heterogeneity and complexity of dermatomyositis in association with neuroendocrine tumors.

Abstract
Dermatomyositis, an autoimmune inflammatory myositis commonly linked to polymyositis, is marked by inflammatory and degenerative transformations impacting muscles, skin, limb girdles, the neck, and the pharynx. These changes result in symmetrical weakness and diverse levels of muscle atrophy. Uncommonly, the condition may impact the esophagus, lungs, and heart. While dermatomyositis is believed to involve genetic, immunological, and environmental factors, its precise etiology remains elusive. Typically, the classical presentation involves a symmetrical proximal myopathy alongside dermatological manifestations such as a purplish-red rash affecting the face, arms, hands, legs, and other areas. Additional symptoms may include dysphagia, myalgia, fever, and weight loss. The primary objectives of managing dermatomyositis are to address muscular weakness, skin manifestations, and any underlying health concerns. Integral to this management is the utilization of physical therapy and rehabilitation interventions. This study introduces a 23-year-old female patient with a noteworthy medical history covering a duration of two months. The patient reported a chief complaint of persistent thigh pain and a concurrent complaint concerning bilateral weakness in upper and lower extremities. Furthermore, the patient faced the additional challenge of difficulty swallowing. Intriguingly, the patient's clinical presentation was marked not only by the aforementioned symptoms but also by the development of a distinctive facial rash. This facial rash was accompanied by symptoms of stiffness in both small and large joints and a reduction in the range of affected joints. The physiotherapeutic assessment revealed quadriparesis of bilateral upper and lower limbs. The rehabilitation programme for the patient was planned by targeting proprioceptors to increase dynamic trunk balance in patients with DM. The Proprioceptive Neuromuscular Facilitation (PNF) technique employs diagonal movement patterns, thereby proving instrumental in enhancing the patient's daily activities. This methodology serves to optimize the individual's capacity to execute routine daily tasks, promoting independence in their daily life. An investigation like the Nerve Conduction Velocity (NCV) report shows the absence of motor excitation, suggesting motor axonal neuropathy. This approach, comprising isometric, concentric, and eccentric contraction exercises, demonstrated efficacy in mitigating muscular weakness, enhancing motor function, and alleviating the diverse symptoms associated with this condition.

Abstract
RATIONALE Patients who have myasthenia gravis or dermatomyositis show clinical signs of muscular weakening. Ocular muscle involvement is uncommon, and symmetrical proximal limb weakness is the typical presentation of dermatomyositis. However, the earliest and most noticeable sign in those with myasthenia gravis is extraocular muscular paralysis. Dermatomyositis is frequently complicated by malignancy, and the common malignancies associated with dermatomyositis vary by region and ethnicity, while thymoma is relatively rare. About 10% to 15% of people with myasthenia gravis have thymoma, which is involved in the etiology of the disease. PATIENT CONCERNS A 68-year-old female presented with ocular muscle weakness for 10 days that manifested as bilateral blepharoptosis with the phenomenon of "light in the morning and heavy in the evening." Imaging examination showed anterior mediastinal thymic tumor with metastasis. DIAGNOSES After a thorough physical examination, we discovered bilateral upper limbs with grade IV muscle strength and the typical rash of dermatomyositis. In combination with elevated serum kinase levels and electromyography suggesting myogenic damage, the patient was finally diagnosed as dermatomyositis with multiple metastases of thymoma. INTERVENTIONS The patient received oral hydroxychloroquine sulfate, topical corticosteroids, and tacrolimus ointment, but these did not work very well. Subsequently, the patient underwent surgery combined with radiotherapy for the thymoma. OUTCOMES Muscle weakness in the patient improved after effective treatment of tumor, and the rash mostly disappeared. CONCLUSION Ocular muscle weakness and thymoma are more common in myasthenia gravis, but we cannot ignore the possibility of dermatomyositis. To further establish the diagnosis, a thorough physical examination and laboratory findings are required. Further tumor screening should be performed for patients with dermatomyositis. Early detection and management of possible tumors are essential to the treatment of dermatomyositis linked to malignancies.

Abstract
OBJECTIVE To establish a prediction model using non-invasive clinical features for early discrimination of DM-ILD in clinical practice. METHOD Clinical data of pediatric patients with JDM were retrospectively analyzed using machine learning techniques. The early discrimination model for JDM-ILD was established within a patient cohort diagnosed with JDM at a children's hospital between June 2015 and October 2022. RESULTS A total of 93 children were included in the study, with the cohort divided into a discovery cohort (n = 58) and a validation cohort (n = 35). Univariate and multivariate analyses identified factors associated with JDM-ILD, including higher ESR (OR, 3.58; 95% CI 1.21-11.19, P = 0.023), higher IL-10 levels (OR, 1.19; 95% CI, 1.02-1.41, P = 0.038), positivity for MDA-5 antibodies (OR, 5.47; 95% CI, 1.11-33.43, P = 0.045). A nomogram was developed for risk prediction, demonstrating favorable discrimination in both the discovery cohort (AUC, 0.736; 95% CI, 0.582-0.868) and the validation cohort (AUC, 0.792; 95% CI, 0.585-0.930). Higher nomogram scores were significantly associated with an elevated risk of disease progression in both the discovery cohort (P = 0.045) and the validation cohort (P = 0.017). CONCLUSION The nomogram based on the ESIM predictive model provides valuable guidance for the clinical evaluation and long-term prognosis prediction of JDM-ILD.

Abstract
An increase in skin-related autoimmune disorders has been reported as an adverse effect of coronavirus disease 2019 (COVID-19) vaccines. We present the case of a 90-year-old Taiwanese female who was newly diagnosed with anti-transcription intermediary factor 1-gamma (anti-TIF1-γ)-positive dermatomyositis (DM) after receiving a second dose of the AstraZeneca COVID-19 vaccine. Under treatment with prednisolone and monoclonal antibody therapy of abatacept, her skin lesions improved, and her muscle power increased. The serum creatinine phosphokinase level decreased from 4858 to 220 U/L, and the anti-TIF1-γ antibody titer decreased from 202 to 99. Flow cytometry data showed an increase in T cells, while NK cells, B cells (CD19), and plasma blasts all decreased. These findings suggest that standard DM treatment might be beneficial to patients with COVID-19 vaccine-induced DM.

Abstract
Dermatomyositis is an inflammatory myopathy characterized by typical skin findings. Cutaneous findings of DM include heliotrope eruption, Gottron papules, Gottron sign, poikiloderma, periorbital edema, facial swelling. The unique cutaneous manifestations of dermatomyositis are often resistant to conventional treatments. Narrowband intense pulsed light is a novel treatment that may reduce vasodilation. Furthermore, it may have a role in regulating inflammation associated with dermatomyositis. We present a case of cutaneous dermatomyositis that was successfully treated with narrowband intense pulsed light.

Clinical Characteristics of Dermatomyositis with Interstitial Lung Disease: A Retrospective Case-Control Study. Rheumatol Ther 2023; 10:635-648. [PMID: 36802052 PMCID: PMC10140193 DOI: 10.1007/s40744-023-00540-6] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2022] [Accepted: 02/06/2023] [Indexed: 02/21/2023] Open
Abstract
INTRODUCTION Interstitial lung disease (ILD) is a common complication of dermatomyositis (DM) and one of the main risk factors for poor prognosis in DM patients. The aim of this study was to reveal the clinical characteristics of DM patients with ILD. METHODS Clinical data from the Second Affiliated Hospital of Soochow University were used to conduct a retrospective case-control study. Univariate and multivariate logistic regression analysis were performed to identify risk factors for ILD in DM. RESULTS A total of 78 DM patients were included in this study, including 38 DM patients with ILD and 40 DM patients without ILD. Compared with patients without ILD, patients with ILD were older (59.6 vs. 51.2 years, P = 0.004), and had higher rates of clinically amyopathic DM (CADM) (45 vs. 20%, P = 0.019), Gottron's papules (76 vs. 53%, P = 0.028), mechanic's hands (13 vs. 0%, P = 0.018), myocardial involvement (29 vs. 8%, P = 0.014), and higher positive rates of anti-SSA/Ro52 (74 vs. 20%, P < 0.001) and anti-melanoma differentiation-associated gene-5 (MDA5) (24 vs. 8%, P = 0.048) antibodies, while albumin (ALB) (34.5 vs. 38.0 g/l, P = 0.006), prognostic nutritional index (PNI) (40.3 vs. 44.7, P = 0.013), the rates of muscle weakness (45 vs. 73%, P = 0.013) and heliotrope rash (50 vs. 80%, P = 0.005) were lower. In addition, the five patients who died were all DM patients with ILD (13 vs. 0%, P = 0.018). Multivariate logistic regression showed that old age (odds ratio [OR] = 1.119, 95% confidence interval [CI] = 1.028-1.217, P = 0.009), Gottron's papules (OR = 8.302, 95% CI = 1.275-54.064, P = 0.027) and anti-SSA/Ro52 (OR = 24.320, 95% CI = 4.102-144.204, P < 0.001) were independent risk factors for ILD in DM. CONCLUSIONS DM patients with ILD usually present with older age, higher rates of CADM, Gottron's papules, mechanic's hands, myocardial involvement, higher positive rates of anti-MDA5 and anti-SSA/Ro52 antibodies, lower ALB, PNI, and lower rates of muscle weakness and heliotrope rash. Old age, Gottron's papules, and anti-SSA/Ro52 were independent risk factors for ILD in DM.

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.

Assessment of Thigh MRI Radiomics and Clinical Characteristics for Assisting in Discrimination of Juvenile Dermatomyositis. J Clin Med 2022; 11:jcm11226712. [PMID: 36431189 PMCID: PMC9693341 DOI: 10.3390/jcm11226712] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2022] [Revised: 09/30/2022] [Accepted: 11/11/2022] [Indexed: 11/16/2022] Open
Abstract
Magnetic resonance imaging (MRI) is an important non-invasive examination in the early diagnosis of juvenile dermatomyositis (JDM). We aimed to evaluate the feasibility of radiomics to establish a quantitative analysis of MRI images. Radiomics and machine learning were used to retrospectively analyze MRI T2 fat suppression sequences and relevant clinical data. The model associated with radiomics features was established using a cohort of patients who underwent thigh MRI at the children's hospital from June 2014 to September 2021. In total, 75 patients with JDM and 75 control children were included in the training cohort (n = 102) and validation cohort (n = 48). The independent factors including lower muscle strength (OR, 0.75; 95% CI, 0.59-0.90), higher creatine kinase (CK) level (OR, 1.65; 95% CI, 1.20-2.38), and higher radiomics score (OR, 2.30; 95% CI, 1.63-3.62) were associated with a clinical diagnosis of JDM. The combined model achieved good discrimination performance compared the radiomics score model under linear discriminant analyses in the training cohort (AUC, 0.949; 95% CI, 0.912-0.986 vs. AUC, 0.912; 95% CI, 0.858-0.967; p = 0.02) and in the validation cohort (AUC, 0.945; 95% CI, 0.878-1 vs. AUC, 0.905; 95% CI, 0.812-0.998; p = 0.03). The combined model showed the diagnostic value was not weaker than the biopsy (AUC, 0.950; 95% CI, 0.919-0.981, n = 150 vs. AUC, 0.952; 95% CI, 0.889-1, n = 72; p = 0.95) and electromyogram (EMG) (AUC, 0.950; 95% CI, 0.919-0.981 vs. AUC, 0.900; 95% CI, 0.852-0.948; p = 0.10) among all the patients. The combination of radiomics features extracted from the MRI and non-invasive clinical characteristics obtained a pronounced discriminative performance to assist in discriminating JDM.

Abstract
Purpose of Review Rituximab has transformed the treatment of B-cell malignancies and rheumatoid arthritis in the past 2 decades. More recently, this anti-CD20 monoclonal antibody has seen increasing usage in the field of dermatology. This review highlights the evidence supporting its use in several important dermatologic conditions. Recent Findings Key recent findings include the 2018 FDA approval of rituximab for the treatment of moderate-to-severe pemphigus. Summary Data from randomized controlled trials have demonstrated the efficacy of rituximab in pemphigus, ANCA-associated vasculitis, and cryoglobulinemic vasculitis. More limited data suggests its use in recalcitrant cases of diseases such as pemphigoid, epidermolysis bullosa acquisita, and dermatomyositis. There is scarce evidence and mixed results for rituximab when studied in cutaneous polyarteritis nodosa and cutaneous lupus erythematosus.

Abstract
Background Cutaneous lupus erythematosus (CLE) and dermatomyositis (DM) are autoimmune diseases that present with a wide variety of cutaneous manifestations. In both cases, first-line therapy includes topical corticosteroids. Patients may present with more widespread disease requiring systemic treatments, including corticosteroids, traditional immunosuppressants, or antimalarials. Due to their complex nature, both CLE and DM remain difficult to treat and continue to cause significant distress to patients. Objective To summarize the most recent literature on the safety and efficacy of novel treatment modalities for CLE and DM. Methods A literature search was conducted on PubMed using search terms “(dermatomyositis) AND (treatment)” and “(cutaneous lupus) AND (treatment)”. Additional search terms included specific names of biologic agents, phosphodiesterase inhibitors (apremilast), and JAK inhibitors. Results JAK inhibitors, PDE-4 inhibitors, and biologics have shown promise in reducing cutaneous symptoms of both CLE and DM, including reduction in SLE Disease Activity Index 2000 (SLEDAI-2K), Cutaneous Lupus Erythematosus Disease Area and Severity Index (CLASI), British Isles Lupus Assessment Group (BILAG), Cutaneous Dermatomyositis Disease Area and Severity Index (CDASI), and Disease Activity Score (DAS). Conclusion While there have been recent advancements in the treatment for CLE and DM, further research and clinical trials are required to better elucidate which therapy is best for individual patients.

Challenge of hepatitis B testing following intravenous immunoglobulin therapy in patients with autoimmune skin diseases. J Dermatol 2022; 49:1049-1051.

Abstract
Intravenous immunoglobulin (IVIg) contains pooled immunoglobulins from the plasma of healthy blood donors. All plasma samples are tested for HIV, hepatitis viruses (A, B, and C), and parvovirus B19. As part of this screening step, nucleic acid amplification technology (NAT) is used and allows the presence of specific antibodies targeting viral structures that are commonly used to test for infection status, such as anti-hepatitis B surface antigen (HBs) or anti-hepatitis B virus core (HBc) antibodies. For this reason, manufacturers point to the possibility of false-positive viral serological test results following IVIg treatment due to the passive transfer of antibodies. IVIg therapy is commonly used to manage patients with severe, treatment-refractory autoimmune skin diseases. The aim of this cohort study was to retrospectively quantify newly-discovered positive serological HBV test results after IVIg treatment in patients with autoimmune skin diseases. Between March 2018 and June 2021, 28 patients with autoimmune skin diseases received IVIg therapy, of whom 17 were longitudinally followed-up. None of the patients had evidence of active HBV infection prior to IVIg therapy. All patients (n = 17) had detectable anti-HBs antibodies and 12 patients had anti-HBc antibodies 4 weeks after commencing IVIg treatment. Passive antibody transfer seems the most likely interpretation. Nevertheless, complete serological hepatitis assessment should be performed to exclude a new infection. We recommend hepatitis screening before IVIg therapy to prevent diagnostic confusion which may arise due to passive antibody transfer.

Abstract
The immune system plays a key role in protecting living beings against bacteria, viruses, and fungi, among other pathogens, which may be harmful and represent a threat to our own health. However, for reasons that are not fully understood, in some people this protective mechanism accidentally attacks the organs and tissues, thus causing inflammation and leads to the development of autoimmune diseases. Remote monitoring of human health involves the use of sensor network technology as a means of capturing patient data, and wearable devices, such as smartwatches, have lately been considered good collectors of biofeedback data, owing to their easy connectivity with a mHealth system. Moreover, the use of gamification may encourage the frequent usage of such devices and behavior changes to improve self-care for autoimmune diseases. This study reports on the use of wearable sensors for inflammation surveillance and autoimmune disease management based on a literature search and evaluation of an app prototype with fifteen stakeholders, in which eight participants were diagnosed with autoimmune or inflammatory diseases and four were healthcare professionals. Of these, six were experts in human–computer interaction to assess critical aspects of user experience. The developed prototype allows the monitoring of autoimmune diseases in pre-, during-, and post-inflammatory crises, meeting the personal needs of people with this health condition. The findings suggest that the proposed prototype—iShU—achieves its purpose and the overall experience may serve as a foundation for designing inflammation surveillance and autoimmune disease management monitoring solutions.

Abstract
Background Dermatomyositis is a rare idiopathic inflammatory disease with diverse presentations that can have varying degrees of cutaneous and systemic involvement. This phenotypic heterogeneity makes DM a therapeutic challenge. Some therapeutic drugs, such as hormones and immunosuppressants, have poor therapeutic effects. In recent years, tofacitinib has been reported to be effective in the treatment of dermatomyositis. Case presentation We report a case of anti-MDA5 antibody-positive dermatomyositis that was relieved after treatment with tofacitinib, during which gallbladder gangrene and suppurative cholecystitis occurred. After cholecystectomy, we continued to use tofacitinib and achieved a good therapeutic effect. Conclusions Tofacitinib is effective in the treatment of anti-MDA5 antibody-positive dermatomyositis, but the risk of infection is increased. It can still be used after infection control. Close follow-up should be performed during the use of tofacitinib.

Abstract
Dermatomyositis (DM) is a systemic autoimmune disease that affects skeletal muscles, the skin, and the lungs. It is characterized by autoantibodies, tissue inflammation, parenchymal cell damage, death, and vasculopathy. In terms of epidemiology, DM affects both children and adults. The current pathophysiology of DM is described as an autoimmune attack on the afflicted organs driven by environmental variables such as UV exposure, medications, infections, and lifestyle choices in genetically predisposed people. DM is also a paraneoplastic condition, which means that cancer may arise before, along with, or following the development of the symptoms of DM. Myositis-specific autoantibodies are associated with phenotypical features and are used for sub-classification of dermatomyositis patients. Because the risk of interstitial lung disease (ILD), internal malignancy, destructive disease trajectory, and maybe a response to medication differs by DM myositis-specific antibody (MSA) group, a better knowledge of MSAs and the validation and standardization of tests employed for detection is crucial for improving diagnosis and treatment. The diagnostic sensitivity and specificity of tests for various MSAs are not ideal, just like with any other test. However, more antibody tests are anticipated to make their way into formal schemata for diagnosis and actionable risk assessment in DM due to worldwide standardization and more extensive research. In this review, we outline crucial aspects for interpreting clinical and pathologic relationships with MSA in DM and critical knowledge and practice gaps that will optimize the clinical benefit and utility of MSAs as diagnostic and prognostic markers.

Abstract
Dermatomyositis is a chronic inflammatory disease involving the skin and muscles. It most commonly occurs in adults with preponderance in females, but pediatric occurrence is also possible. The risk of malignancy in adult patients with dermatomyositis was reported to be 4.66-fold higher compared to that in the general population. A significantly increased risk of malignancy was reported within the first 12 months following the diagnosis of dermatomyositis (standardized incidence ratio equaled 17). One of the characteristic laboratory findings associated with dermatomyositis is the presence of circulating autoantibodies which are classified into two subgroups: myositis-specific and myositis-associated autoantibodies. It was shown that specific types of antibodies might be associated with an increased risk of malignancy. Current literature data indicate that the strongest correlation with malignant diseases was reported in anti-TIF1-γ-positive patients who were at a 9.37-fold higher risk of cancer. A 3.68-fold increase in the risk of cancer was also reported among patients with anti-NXP2 antibodies. Malignant diseases were reported in 14-57% of patients with anti-SAE antibodies. The presence of other autoantibodies may also be associated with an increased risk of malignancy. These data indicate that patients with circulating anti-TIF1-γ, anti-NXP2, and anti-SAE should be very closely monitored for dermatomyositis-associated malignant comorbidities. The aim of this review is to summarize the current data regarding the link between malignancy and the presence of specific antibodies in patients with dermatomyositis.

Abstract
Dermatomyositis is associated with malignancies and is known to have systemic involvement. However, associations with bone diseases have not been well described in the current literature. This article describes the second reported case of the co-existence of dermatomyositis and Paget's Disease of Bone (PDB), but is the first report to describe such co-existence in a specific subtype of dermatomyositis - hypomyopathic dermatomyositis. Our patient was a 51-year-old woman who presented with prolonged fever, myalgia, morning stiffness, and rashes pathognomonic of dermatomyositis. There was no muscle weakness clinically, although muscle enzymes were raised and electromyogram revealed myopathic changes. Further imaging showed the incidental finding of a T11 vertebral bone lesion, of which biopsy confirmed the diagnosis of PDB. Our report illustrates the diagnostic approach to bone lesions in patients with dermatomyositis, and takes a closer look at the pathophysiology and management implications of the co-occurrence of these two rare diseases.

Abstract
No pharmaceutical products have been demonstrated to be safe and effective to specifically treat coronavirus disease 2019 (COVID-19); therefore, the therapy administered to infected patients remains symptomatic and empiric. Alongside the development of new, often high-cost drugs, a different tactic is being applied in parallel, investigating long-established, inexpensive medications originally designed for a variety of diseases to study their potential in treating COVID-19. The skin is the largest organ of the human body. With more than 3,000 skin conditions identified, the specialty of dermatology offers a rich armamentarium of systemic therapeutic agents aimed to treat the various chronic immunologically mediated, metabolic, infectious, occupational, inherited, or paraneoplastic dermatoses. Dermatologists have extensive experience with many drugs that have demonstrated promising in vitro antiviral action (directly targeting the viral replication). Many of these drugs have been used as nonspecific immunosuppressive strategies, such as glucocorticoids, synthetic antimalarials, colchicine, or other immunomodulators, and a number of targeted therapeutics have been directed at controlling hyperinflammatory processes similar to the "cytokine storm" associated with COVID-19 infection. We discuss several dermatologic drugs that have already been used or may have a promising role in the treatment of COVID-19.

Abstract
Dermatomyositis is a rare disease affecting primarily skin and muscles and is associated with malignancies, especially in at-risk patients. Clinical presentations vary widely but proximal muscle weakness and typical skin findings should prompt consideration of the diagnosis. Immunosuppressive therapy is required, as is continued screening for malignant disease during follow-up.

Abstract
Idiopathic inflammatory myopathy (IIM) is the umbrella term including dermatomyositis (DM), polymyositis (PM), overlap myositis (OM), sporadic inclusion body myositis (IBM) and necrotising autoimmune myopathy (NAM), also known as immune-mediated necrotising myopathy. There is some debate as to whether PM exists as a discrete entity, or perhaps is an overly generalising term encompassing connective tissue disease associated myositis, or OM, and the previously poorly recognised NAM. As such, PM will not be covered in detail in this review. DM, OM and NAM all present similarly, with proximal weakness and elevated creatine kinase (CK) level. By contrast, IBM preferentially involves the long finger flexors and quadriceps, and presents with a normal or only mildly elevated CK. Developments in serological testing and imaging are shifting the diagnostic paradigm away from a reliance on histopathology. The therapeutic armamentarium for IIM continues to evolve, with intravenous immunoglobulin and rituximab proving to be successful for refractory disease. This review will provide a diagnostic algorithm for the clinician to help distinguish between IIM subtypes - with emphasis on clinical assessment, serology and imaging, as well as discussion of therapeutic options and escalation of immunotherapy.

Abstract
Connective tissue diseases (CTDs) encompass a broad spectrum of clinical presentations that involve multidisciplinary management. Cutaneous findings are common in CTD and careful examination of these features aids in appropriate diagnosis and subsequent evaluation. Thorough work-up of CTD is crucial to properly identify disease subtypes and systemic involvement. Management plans can be developed based on diagnosis and systemic manifestations of disease. Disease management often requires treatment with pharmacotherapies with potential for toxicities, further underscoring the importance of diagnostic accuracy in this patient population. Evolving research strives to better elucidate the pathogenic mechanisms of CTDs allowing for more targeted treatment modalities.

Abstract
Cutaneous manifestations are common across the spectrum of autoimmune diseases. Connective tissue diseases manifesting in the skin are often difficult to classify and require integration of clinical, histopathologic, and serologic findings. This review focuses on the current understanding of the molecular and immune drivers involved in the pathogenesis of cutaneous lupus erythematosus, dermatomyositis, scleroderma/systemic sclerosis, and mixed connective tissue disease. Recent research advances have led to the emergence of new ancillary tools and useful diagnostic clues of which dermatopathologists should be aware to improve diagnostic accuracy for these diseases.

Abstract
Autoimmune diseases include rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), systemic vasculitis, dermatomyositis, systemic sclerosis (SSc), mixed connective tissue disease, autoimmune hemolytic anemia, autoimmune thyroiditis (AITD) and ulcerative colitis. Exosomes exist in body fluids, including blood, saliva, urine, cerebrospinal fluid and milk. They are mainly derived from the invagination of intracellular lysosomal particles, which are released into the extracellular matrix after fusion of the outer membrane of the exosomes with the cell membrane. Exosomes mediate intercellular communication and regulate the biological activity of receptor cells by carrying proteins, nucleic acids and lipids. Evidences show that exosomes are involved in the pathogenesis of various autoimmune diseases. In view of the important roles of exosomes in autoimmune diseases, this work systematically reviewed the effects of exosomes on the pathogenesis of autoimmune diseases, especially the regulatory roles of exosome derived microRNAs (miRNAs) in the pathogenesis of RA, SLE, dermatomyositis, SSc, AITD and ulcerative colitis. The review of the roles of exosomes in autoimmune diseases will help to clarify the pathogenesis of these diseases and explore new diagnostic markers and therapeutic targets.

Abstract
Folic acid (FA) is the synthetic surrogate of the essential B vitamin folate, alternatively named folacin, pteroylglutamic acid or vitamin B9. FA is an electroactive compound that helps our body to create and keep our cells healthy: it acts as the main character in a variety of synthetic biological reactions such as the synthesis of purines, pyrimidine (thus being indirectly implied in DNA synthesis), fixing and methylation of DNA. Therefore, physiological folate deficiency may be responsible for severe degenerative conditions, including neural tube defects in developing embryos and megaloblastic anaemia at any age. Moreover, being a water-soluble molecule, it is constantly lost and has to be reintegrated daily; for this reason, FA supplements and food fortification are, nowadays, extremely diffused and well-established practices. Consequently, accurate, reliable and precise analytical techniques are needed to exactly determine FA concentration in various media. Thus, the aim of this review is to report on research papers of the past 5 years (2016-2020) dealing with rapid and low-cost electrochemical determination of FA in food or biological fluid samples.

Abstract
Vaginal administration is a promising route for the local treatment of infectious vaginal diseases since it can bypass the first-pass metabolism, drug interactions, and adverse effects. However, the commercial products currently available for topical vulvovaginal treatment have low acceptability and do not adequately explore this route. Mucoadhesive systems can optimize the efficacy of drugs administered by this route to increase the retention time of the drug in the vaginal environment. Several polymers are used to develop mucoadhesive systems, among them chitosan, a natural polymer that is highly biocompatible and technologically versatile. Thus, the present review aimed to analyze the studies that used chitosan to develop mucoadhesive systems for the treatment of local vaginal infections. These studies demonstrated that chitosan as a component of mucoadhesive drug delivery systems (DDS) is a promising device for the treatment of vaginal infectious diseases, due to the intrinsic antimicrobial activity of this biopolymer and because it does not interfere with the effectiveness of the drugs used for the treatment.

Abstract
The past 15 years has seen significant advances in the characterization of myositis-specific autoantibodies (MSAs) and their associated phenotypes in patients with dermatomyositis (DM). As more careful studies are performed, it is clear that unique combinations of clinical and pathological phenotypes are associated with each MSA, despite the fact that there is considerable heterogeneity within antibody classes as well as overlap across the groups. Because risk for interstitial lung disease (ILD), internal malignancy, adverse disease trajectory, and, potentially response to therapy differ by DM MSA group, a deeper understanding of MSAs and validation and standardization of assays used for detection are critical for optimizing diagnosis and treatment. Like any test, the diagnostic sensitivity and specificity of assays for various MSAs is not perfect. Currently tests for MSAs are helpful at minimum for a clinician to assess relative risk or contribute to diagnosis and perhaps counsel the appropriate patient about what to expect. With international standardization and larger studies it is likely that more antibody tests will make their way into formal schemata for diagnosis and actionable risk assessment in DM. In this review, we summarize key considerations for interpreting the clinical and pathologic associations with MSA in DM and identify critical gaps in knowledge and practice that will maximize their clinical utility and utility for understanding disease pathogenesis.

Abstract
OBJECTIVES Dermatomyositis (DM)-related acute/subacute interstitial lung disease (A/S-ILD) remains a big therapeutic challenge due to its insidious onset and rapid development. In the present study, we aimed to investigate the association between clinical features of DM and ILD. METHODS We retrospectively assessed skin manifestations, muscle damage, laboratory tests, concurrent ILD and malignancy in 207 patients with DM and analyzed the high-risk factors for ILD. RESULTS In the 207 DM patients, 153 patients had ILD, in which 131 had chronic ILD (CILD) and 22 had A/S-ILD. The proportions of mechanic's hands, palmar papules and muscle weakness, as well as anti-melanoma differentiation-associated gene 5 (MDA5) antibody and lactic dehydrogenase (LDH), alanine aminotransferase (ALT) and ferritin in the ILD group were significantly higher compared with the non-ILD group. The onset age over 56 years, mechanic's hands and muscle weakness were independent predictive factors for ILD. The proportions of palmar papules, palmar erythema, anti-MDA5 antibody, ALT, aspartate aminotransferase (AST), LDH and erythrocyte sedimentation rate in the A/S-ILD group were higher compared with the CILD group. Palmar erythema and palmar papules were independent predictive factors for A/S-ILD. Palmar papules were positively correlated with anti-MDA5 antibody. CONCLUSION The onset age over 56 years, mechanic's hands or muscle weakness predicted the incidence of DM-related ILD, while palmar erythema or palmar papules could predict potential DM-related A/S-ILD.

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) in adults has a prevalence of 6-7 per 100,000 population per year. This dedicated compact overview was prepared due to an increasing incidence as well as an often underestimated systemic involvement and new developments in myositis-specific antibodies (MSA). The spectrum of clinical dermatological and systemic symptoms is described. Related diagnostic procedures are depicted, and therapeutic regimens based on the German S2k guidelines and the current literature are presented. The urgency of an early diagnosis is emphasized as about 30 % of patients with DM manifest a tumor. Etiopathology is often associated with pulmonary fibrosis, and inflammation of myositis can cause irreversible muscle damage. Clinical signs and correct interpretation of serological markers can deliver valuable information on the extent of DM, and provide an indication for further diagnostic procedures, prognosis and choice of therapy.

Abstract
Background Invasive fungal pneumonia is a severe infectious disease with high mortality in immunocompromised patients. However, the clinical diagnosis of the pathogen(s) remains difficult since microbiological evidence is difficult to acquire. Case presentation Here, we report a case of pulmonary fungal infection detected by next-generation sequencing (NGS) of bronchoalveolar lavage fluid (BALF) in a 61-year-old male with corticosteroid-treated dermatomyositis. Cytomegalovirus and influenza A virus infections were confirmed by nucleic acid detection and treated with antiviral medicine. The patient had been diagnosed with severe pneumonia and treated with empiric broad-spectrum antibacterial and antifungal drugs before bronchoscopy was performed. The patient responded poorly to those empiric treatments. Three fungi were found by NGS in the BALF, namely, Pneumocystis jirovecii, Aspergillus fumigatus and Rhizopus oryzae. After adjusting the patient’s treatment plan according to the NGS results, he improved significantly. Conclusions This case highlights the combined application of NGS and traditional tests in the clinical diagnosis of pulmonary invasive fungal disease. NGS is proposed as an important adjunctive diagnostic approach for identifying uncommon pathogens.

Macrophage activation syndrome in adult dermatomyositis: a case-based review. Rheumatol Int 2020; 40:1151-1162. [PMID: 32356114 DOI: 10.1007/s00296-020-04590-9] [Citation(s) in RCA: 22] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2020] [Accepted: 04/18/2020] [Indexed: 12/22/2022]
Abstract
Macrophage activation syndrome (MAS) is a severe and life-threatening syndrome associated with autoimmune diseases, characterized by fever, hepatosplenomegaly, and pancytopenia. Dermatomyositis (DM) is one of the causes of MAS; however, its clinical characteristics in DM patients remain unclear. This study aimed to present a case of anti-melanoma differentiation-associated gene 5 (MDA5) antibody-positive DM complicated by MAS in a 29-year-old woman and to review the literatures including similar cases. Even though symptoms and cytopenia of our patient were refractory to combination therapy, including glucocorticoids, immunosuppressants, and plasma exchange, the administration of rituximab (RTX) resulted in rapid clinical improvement and glucocorticoid reduction. The literature review revealed 18 adult patients with DM associated MAS. Most patients developed MAS within 3 months from DM onset. A monotherapy of glucocorticoid was insufficient to control the disease, and the mortality of MAS in DM was higher than that of MAS in other rheumatic diseases, despite being treated by various means. RTX may be an effective treatment for patients with DM complicated by MAS who are refractory to conventional therapy. Anti-MDA5 antibody could influence the development of MAS; however, further investigations are needed to elucidate the association between myositis-specific antibody and MAS.
