How Lung Bacteria Affect Dermatomyositis and Lung Disease

Researchers are studying how the microscopic bacteria living in your lungs (your lung microbiome) may affect a rare autoimmune disease called anti-MDA5 antibody positive dermatomyositis, which causes both skin inflammation and progressive lung disease. This study will collect lung fluid samples from patients who have this condition and lung involvement to analyze the relationship between what bacteria live in the lungs and how the disease develops and progresses.

Dermatomyositis with lung complications is a serious condition that is still not fully understood. Scientists believe that the balance of bacteria in the lungs may play a role in how the immune system attacks the body in this disease. By studying this connection, researchers hope to find new ways to predict, prevent, or treat the lung problems that come with this condition.
