- Registration Number
- NCT06203249
- Lead Sponsor
- Chinese PLA General Hospital
- Brief Summary
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.
- Detailed 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.
