Details and patient eligibility

About

The purpose of this study was to analyze the relationship between the microbial community, host immunity and the presence or absence of concurrent rapidly progressive interstitial lung disease patients with anti-MDA5 antibody positive dermatomyositis.

Full description

Methods: Bronchoalveolar lavage specimens of patients with anti-MDA5 antibody positive dermatomyositis and interstitial lung disease were collected and studied to analyze the relationship between the composition of patients' microecology and the occurrence and development of disease.
