Background: Lung damage during amyopathic dermatomyositis (ADM) associated with auto antibodies anti MDA-5 is serious. We report a rare observation of a severe ADM associated to anti MDA-5 antibodies complicated with diffuse interstitial lung disease (ILD) rapidly extensive and fatal.
Observation: We report the observation of a Tunisian adult who was admitted for ADM. The anti MDA-5 antibodies were detected. He developed an ILD rapidly extensive to fibrosis. Corticosteroids were unefficient and he deceded of pneumomediastin and refractory respiratory distress.
Conclusion: This observation illustrates the severity of ADM with anti MDA-5 antibodies. Every clinician should detect any ILD to avoid the progression to fibrosis.

: Interstitial lung disease (ILD) is a common extra-muscular manifestation of idiopathic inflammatory myopathies (IIMs), often associated with a poorer prognosis and increased mortality risk. : This retrospective study aimed to characterize lung involvement and treatment response in an IIM cohort at a Portuguese tertiary center, followed between June 2016 and March 2024. We analyzed data from high-resolution computed tomography (HRCT) scans and pulmonary function tests (PFTs) to assess associations with autoantibody profiles and treatment regimens.

Article Synopsis
- Rapidly progressive interstitial lung disease (RP-ILD) is a serious complication in patients with idiopathic inflammatory myopathy (IIM), often leading to poor outcomes, making the need for effective treatments essential.
- Plasma exchange (PE) may help by quickly removing harmful substances from the blood, and this study assesses its effectiveness when combined with immunosuppressants in improving survival rates and reducing inflammatory markers.
- Results showed an 80% survival rate at 6 months for patients undergoing PE, which was significantly better than for those not receiving PE, suggesting its potential as a beneficial treatment option for IIM-RP-ILD.

Article Synopsis
- Dermatomyositis is a complex disease where about 7-10% of patients have the Anti MDA-5 antibody, often leading to severe symptoms like skin ulcers and quickly worsening lung disease.
- A case study highlights a 22-year-old male who experienced severe respiratory distress and ultimately died from complications related to both dermatomyositis and H1N1 influenza.
- Postmortem tests revealed the presence of Anti MDA-5 and Ro-52 antibodies, suggesting they are significant biomarkers for diagnosing and assessing the prognosis of patients with related inflammatory conditions, particularly those involving lung issues.

Article Synopsis
- The study aimed to create an easy-to-use nomogram for predicting interstitial lung disease (ILD) in patients with idiopathic inflammatory myositis (IIM) based on a large retrospective analysis of 205 patients from Shantou Central Hospital.
- Using LASSO regression, researchers identified four risk factors (age, respiratory symptoms, MDA-5 antibodies, and anti-ARS antibodies) and found that including KL-6 levels and LUS B-lines significantly improved the model's predictive accuracy.
- The final model showed strong predictive performance with an ROC AUC of up to 0.951, and a web version was created to enhance accessibility for clinicians.
