Anti-melanoma Differentiation-associated Gene 5 Antibody-positive Dermatomyositis Presenting as Refractory Gingivitis at the First Clinical Manifestation. | LitMetric
We herein report a case of melanoma differentiation-associated gene 5 (MDA5) antibody-positive dermatomyositis that developed in a patient with refractory gingivitis. The diagnosis of anti-MDA5 antibody-positive dermatomyositis was made based on a characteristic skin rash, weakness of proximal muscles, interstitial pneumonia, and positivity for anti-MDA5 antibody. The patient was started on triple therapy with high-dose prednisolone, tacrolimus, and intravenous cyclophosphamide. After treatment, the refractory gingivitis disappeared, and the other skin rash and interstitial lung disease also improved. In the diagnosis and treatment of anti-MDA5 antibody-positive dermatomyositis, it is necessary to pay attention to the intraoral findings, including the gingiva.
Background: Anti-melanoma differentiation-associated gene 5 antibody-positive dermatomyositis (anti-MDA5+DM) patients are associated with considerable mortality, and opportunistic infections including Pneumocystis jirovecii pneumonia (PJP)is the main cause. This study was to identify clinical characteristics, risk factors, and prognostic factors of PJP diagnosed by bronchoalveolar lavage fluid (BALF) metagenomic next-generation sequencing (mNGS) in anti-MDA5+ DM patients.
Methods: In this retrospective observational study, all patients admitted with suspected pneumonia were detected for mNGS in BALF.
The skin ulcers sometimes appear in patients with anti-melanoma differentiation-associated gene 5 (MDA5) antibody-positive dermatomyositis (DM), and usually associates with disease activity. Here, we report a case of 41-year-old woman with anti-MDA5 antibody-positive DM, who developed refractory skin ulcers during the remission induction therapy, which were proven to be associated with clinically silent Staphylococcus aureus bacteremia with septic thrombi in her lung. The patient was referred to our hospital for the treatment of amyopathic DM with interstitial lung disease.
Objectives: To investigate the clinical characteristics of pharyngeal and laryngeal lesions in patients with anti-melanoma differentiation-associated gene 5 antibodies-positive dermatomyositis (anti-MDA5-positive DM).
Methods: Serological indicators of 131 anti-MDA5-positive DM patients were analysed. All 35 patients with pharyngeal and laryngeal symptoms underwent electronic laryngoscopy examinations.
Pulmonary complications are a significant health issue for patients with idiopathic inflammatory myopathies (IIMs) in South Africa, causing high morbidity and mortality rates.
A study reviewed clinical records of adult IIM patients with respiratory issues in a tertiary care facility, revealing that most patients suffered from dermatomyositis and exhibited symptoms like dyspnoea and dry cough.
Interstitial lung disease (ILD) emerged as the most common complication, with associations found between respiratory symptoms and poorer lung function outcomes over time.
