OBJECTIVE: To endoscopically assess the upper digestive tract of adult patients with newly diagnosed dermatomyositis; to correlate possible changes in the gastrointestinal tract with demographic, clinical and laboratory features in this population.
METHOD: A cross-sectional study evaluating 65 newly diagnosed dermatomyositis cases from 2004 to 2015 was carried out. We excluded patients with clinically amyopathic dermatomyositis, overlap dermatomyositis, polymyositis, liver diseases, prior gastric surgery, upper gastrointestinal tract symptoms (except for upper dysphagia), systemic infections, alcohol consumption and smoking.
RESULTS: Mean age of patients was 44.9 years, with disease duration of four months. Endoscopic findings were observed in 70.8% of patients. (1) Esophageal disease/gastric distress was documented in 18.5% of patients: erosive distal esophagitis (16.9%) and non-erosive distal esophagitis distal (1.5%); (2) gastric distress in 63.1% of cases: antral gastritis (42.3%) and pangastritis (27.8%); (3) duodenal involvement in 15.4% of patients: bulbar duodenitis (10.9%) and duodenal ulcers (7.7%). There were no neoplasic lesions. On multivariate analysis, erosive distal esophagitis was less associated with older patients. Males had a higher prevalence of erosive gastritis. Enanthematous pangastritis was less associated with lesions with "V-neck" sign lesions.
CONCLUSIONS: This study provides the first estimates of the prevalence of high endoscopic findings in adult patients with newly diagnosed dermatomyositis. The results may be relevant to guide conduct in digestive disorders with upper digestive endoscopy, and point to the need for pharmacological prevention of digestive tract lesions in these patients. Further studies are needed to validate this data and evaluate patients with dyspeptic symptoms.
