HRCT features of interstitial lung disease in dermatomyositis with anti-CADM-140 antibody

Anti-CADM-140/MDA5 antibody and clinical subsets of dermatomyositis

The clinical features of dermatomyositis (DM) have a close relationship with myositis-specific antibodies. Clinically amyopathic dermatomyositis (CADM) is a subgroup of DM, which manifests as characteristic skin symptoms compatible with DM, such as Gottron's sign and heliotrope rash with no or mild muscle symptoms. Sometimes, a life-threatening rapidly progressing interstitial lung disease can ...

Myositis autoantibodies in Korean patients with inflammatory myositis: Anti-140-kDa polypeptide antibody is primarily associated with rapidly progressive interstitial lung disease independent of clinically amyopathic dermatomyositis

BACKGROUND To investigate the association between myositis autoantibodies and clinical subsets of inflammatory myositis in Korean patients. METHODS Immunoprecipitation was performed using the sera of classic polymyositis (PM) (n = 11) and dermatomyositis (DM) (n = 38) patients who met the Bohan and Peter criteria for definite inflammatory myositis. A panel of defined myositis autoantibodies w...

Anti-glycyl tRNA synthetase antibody associated interstitial lung disease without symptoms of polymyositis/dermatomyositis.

A Case of Sarcoidosis with Interstitial Lung Disease Mimicking Clinically Amyopathic Dermatomyositis and Rapidly Progressive Interstitial Lung Disease

Here, we report a patient with sarcoidosis who developed edematous erythema and interstitial lung disease. At the initial visit, clinically amyopathic dermatomyositis (CADM) with rapidly progressive interstitial lung disease (RP-ILD) was suspected because he had progressive dyspnea but no muscle weakness. The presence of anti-CADM-140/MDA5 autoantibodies was immediately assessed to facilitate a...

Assessment of anti-MDA5 antibody as a diagnostic biomarker in patients with dermatomyositis-associated interstitial lung disease or rapidly progressive interstitial lung disease

Anti-melanoma differentiation-associated protein 5 (MDA5) antibody have been found in dermatomyositis (DM)-associated interstitial lung disease (DM-ILD) and DM-associated rapidly progressive ILD (DM-RPILD). Due to the conflicting results regarding the association between anti-MDA5 antibody and DM-ILD or DM-RPILD and the diagnostic value of this antibody for DM-ILD and DM-RPILD, we performed thi...
