dermatomyositis dysphagia

BACKGROUND: Spontaneous intramuscular hemorrhage (SIH) is a rare but life-threatening complication of dermatomyositis (DM). The pathogenetic mechanism and management of intramuscular hematoma in these patients remains unclear. Here we discuss a case of recurrent hemorrhage in a patient with cancer-associated DM, and review the relevant literature for timely diagnosis and treatment. CASE PRESENTATION: A 53-year-old male patient presented with rashes, muscle weakness, and dysphagia and was diagnosed with DM...

Dermatomyositis (DM) is a systemic autoimmune disease that primarily affects the skin and muscles. The hallmark skin manifestation is a violaceous rash on the face, neck, shoulders, upper chest, and extensor surfaces of the arms and legs, which is often accompanied by edema and can be exacerbated by exposure to sunlight. Generalized limb edema and dysphagia are rare presentations of dermatomyositis. Here we present a case of a 69-year-old woman presenting with generalized limb swelling, periorbital swelling, and dysphagia which was diagnosed as dermatomyositis based on a combination of clinical, laboratory, and imaging findings...

PURPOSE OF REVIEW: The purpose of this article is to discuss the diagnosis and treatment of diseases that affect both the skin and the esophagus. RECENT FINDINGS: The diagnosis of dermatological conditions that affect the esophagus often requires endoscopy and biopsy with some conditions requiring further investigation with serology, immunofluorescence, manometry, or genetic testing. Many conditions that affect the skin and esophagus can be treated successfully with systemic steroids and immunosuppressants including pemphigus, pemphigoid, HIV, esophageal lichen planus, and Crohn's disease...

PURPOSE OF REVIEW: Idiopathic inflammatory myopathies (IIM) are a complex family of autoimmune systemic disorders which often affect muscle and/or skin. IIM cause significant morbidity and mortality, but optimal treatment is uncertain. This review provides a practical guide for using intravenous immunoglobulin (IVIG) and subcutaneous immunoglobulin (SCIG) in the management of IIM, including dermatomyositis (DM), polymyositis (PM), immune-mediated necrotizing myositis (IMNM), and spontaneous inclusion body myositis (IBM), based on relevant recent literature and experience...

OBJECTIVES: This study aims to describe and compare the demographic, clinical, and laboratory characteristics and follow-up of representative samples of patients with myopathies and systemic sclerosis overlap syndromes (Myo-SSc) from two tertiary centers. PATIENTS AND METHODS: This is a cross-sectional and retrospective study conducted between January 2000 and December 2020. Fourty-five patients were analyzed with Myo-SSc (6 males, 39 females; mean age: 50.2±15...

OBJECTIVES: Idiopathic inflammatory myositis (IIM) in Saudi patients has been poorly studied owing to the lack of available data. This study aimed to identify the clinical and laboratory features of patients at a single tertiary care center. METHODS: This retrospective study reviewed the medical records of Prince Sultan Military Medical City, Riyadh, Saudi Arabia to collect clinical and laboratory data between December 2022 and February 2017 as follows: age at disease onset, gender, follow-up duration and disease duration; clinical symptoms; laboratory result; presence and type of myositis-specific autoantibody or myositis-associated autoantibody; and type of immunosuppression, presence of malignancy, disease course, and outcome...

To explore the clinical significance of anti-cytosolic 5'-nucleoditase 1A (NT5c1A) antibody seropositivity in inflammatory myopathies, we measured anti-NT5c1A antibodies and analyzed their clinical features. Anti-NT5c1A antibodies were measured in the sera of 103 patients with inflammatory myopathies using an enzyme-linked immunosorbent assay. Positivity for anti-NT5c1A antibody was found in 13 (12.6%) of 103 patients with inflammatory myopathy. Anti-NT5c1A antibody was most frequently identified in patients with inclusion body myositis (IBM) (8/20, 40%), followed by dermatomyositis (2/13, 15...

BACKGROUND: Dermatomyositis (DM) is a rare autoimmune disease characterized by distinctive skin rash, muscle inflammation with symmetrical and progressive muscle weakness, and elevated serum levels of muscle-associated enzymes. DM may affect skeletal muscles involved in swallowing, leading to dysphagia, which can negatively impact individual's physical and psychosocial well-being. Despite this, dysphagia in patients with DM remains poorly understood. This systematic review and meta-analysis aimed to evaluate the prevalence and clinical features of dysphagia in patients with DM and juvenile DM (JDM)...

OBJECTIVE: Among specific autoantibodies in DM, the anti-small ubiquitin-like modifier activating enzyme (SAE) antibody is rare. We aim to describe the clinical characteristics, cancer prevalence, and muscle pathology of anti-SAE-positive DM. METHODS: Patients with a diagnosis of DM and sera positive for the anti-SAE antibody were recruited from 19 centres in this retrospective observational study. The available muscular biopsies were reviewed. We conducted a comparison with anti-SAE-negative DM and a review of the literature...

BACKGROUND: Idiopathic inflammatory myopathies (IIM) are rare diseases for which there is a paucity of data in Africa. We undertook a retrospective records review of clinical and laboratory features of patients with IIM attending a tertiary service in Gauteng, South Africa. MATERIALS AND METHODS: Case records of patients seen between January 1990 and December 2019 and fulfilling the Bohan and Peter criteria for IIM were reviewed for demographics, clinical features, special investigations and drug therapy...

BACKGROUND: Juvenile dermatomyositis (JDM) is the most common inflammatory myopathy in the pediatric population and can represent a medical emergency. However, many features of JDM remain poorly understood, disease presentation is highly variable, and predictors of disease course have yet to be identified. METHODS: This retrospective chart review included 47 JDM patients seen at a tertiary care center over a 20-year period. Characteristics such as demographics, clinical signs and symptoms, antibody positivity, dermatopathology features, and treatments were recorded...

Dermatomyositis is an inflammatory disease that affects muscle strength and causes skin manifestations. There is an increased incidence of cancer in patients with this diagnosis although the pathophysiology of this association is still not completely understood. We report a case of a 65-year-old man who presented to the emergency department with proximal muscle weakness, weight loss, dysphagia, enlarged supraclavicular lymph nodes, an erythematous rash in the malar and supraciliary regions, and papules in the extensor metacarpophalangeal and interphalangeal joints...

INTRODUCTION: This study aimed to determine the clinical profile and outcome of anti-transcriptional intermediary factor 1 gamma autoantibody (anti-TIF1-γ Ab)-positive dermatomyositis patients and propose cancer screening programmes based on regional cancer trends. METHOD: Data on history, physical findings and investigations were collected using chart review on dermatomyositis patients seen at a tertiary hospital in Singapore from 1 January 2015 to 30 June 2021...

OBJECTIVES: Inclusion body myositis (IBM) is the most common idiopathic inflammatory myopathy (IIM) above the age of 50 with a distinct clinical phenotype of progressive, painless, asymmetric weakness predominantly involving the long finger flexors and quadriceps. In this study, we compared comorbidities in IBM with other IIMs (i.e., dermatomyositis (DM) and polymyositis (PM)) from the United States National Inpatient Sample Database. METHODS: We identified patients with a primary diagnosis of IBM or IIM from the National Inpatient Sample (NIS) from 2012 to 2018...

Dysphagia is known to occur in patients with dermatomyositis. However, the sudden-onset dysphagia without other symptoms can make diagnosis and treatment challenging. Two patients who did not have a severe muscle weakness complained of the sudden inability to swallow solids and liquids. The muscle biopsy results showed the perifascicular atrophy, and the patients were diagnosed with dermatomyositis. Videofluoroscopy revealed an inadequate pharyngeal contraction and a decreased upper esophageal sphincter opening with silent aspiration...

Pneumomediastinum (PnM), pneumatosis intestinalis (PI), and pneumoperitoneum (PP) are rare complications of inflammatory myositis. We present a 59-year-old polymyositis (PM) patient who experienced all three complications simultaneously. The patient who presented with proximal muscle weakness, dysphagia, and weight loss was diagnosed with PM due to elevated muscle enzymes and consistent electromyography and muscle biopsy with inflammatory myopathy. On the 45th day of her immunosuppressive treatment, PnM, PI, and PP were detected incidentally in 18 F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) scan performed for severe weight loss and treatment-resistant severe disease...

INTRODUCTION: Juvenile Dermatomyositis (JDM), a severe and rare autoimmune disease, is the most common idiopathic inflammatory myopathy in children. We describe the clinical features of a large single-centre cohort. METHODS: We studied an inception cohort (0-18 years old) referred for diagnosis to the JDM clinic at The Hospital for Sick Children (SickKids), between January 1989 and September 2017. Probable or definite diagnosis of JDM was done according to the 2017 ACR/EULAR Criteria...

Objectives: Studies concerning myocardial involvement (MI) in patients with anti-melanoma differentiation-associated gene 5 antibody-positive dermatomyositis/clinically amyopathic dermatomyositis (anti-MDA5 Ab+ DM/CADM) are scarce. We aimed to characterize MI in our anti-MDA5 Ab+ DM/CADM cohort and to investigate its association with prognosis. Methods: In this single-center retrospective study, anti-MDA5 Ab+ hospitalized DM/CADM patients who underwent transthoracic echocardiography (TTE) were enrolled...

BACKGROUND: The myositis autoantibodies have been widely used clinically in recent years for the identification of an autoantibody-associated clinical phenotype in dermatomyositis (DM) patients. However, correlations between myositis autoantibodies and clinical presentations in different populations are lacking, especially in Taiwan. OBJECTIVES: To investigate the correlations among cutaneous manifestations, myositis autoantibodies, and systemic diseases, including interstitial lung disease (ILD) and internal malignancy...

RATIONALE: Muscle weakness due to cancer-associated dermatomyositis (CADM) can be misdiagnosed as cancer cachexia and disuse atrophy. PATIENT CONCERNS: A 75-year-old female was admitted to our institute with muscle weakness, dysphagia, and suspected gallbladder cancer. Computed tomography and cytopathological examinations of the liver biopsy and fine-needle aspiration from swollen lymph nodes using endoscopic ultrasonography revealed cancer in the gallbladder body and metastasis to the lymph nodes around the abdominal aorta...
