Background: The anti-melanoma differentiation-associated gene 5 (anti-MDA5) antibody-positive dermatomyositis is known for its association with rapidly progressive interstitial lung disease (RP-ILD) and ulcerative skin lesions, often presenting with or without muscle involvement. The aim of this study was to identify distinct clinical and laboratory features that could be used to evaluate disease progression in an ethnically diverse cohort of anti-MDA5 dermatomyositis patients at a U.S.

A 59-year-old female with anti-MDA5 antibody-positive dermatomyositis was treated with prednisolone, tacrolimus, cyclophosphamide, tofacitinib, and plasma exchange. Five months post-treatment, elevated β-D-glucan levels and a pulmonary shadow on CT were noted. was identified, leading to voriconazole initiation.

To describe the clinical characteristics and to explore the prognostic factors of concurrent pneumonia (PJP) in patients with idiopathic inflammatory myopathy (IIM). We retrospectively enrolled consecutive IIM patients diagnosed with PJP at our center between January 2014 and December 2022. Fifty-eight IIM-PJP patients were enrolled in our study, with the age of 26-79 (56.

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.
Refractory skin ulcers and afebrile bacteremia with Staphylococcus aureus in anti-melanoma differentiation-associated gene 5 antibody-positive dermatomyositis: a case report.

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.
