Depression is common in patients with chronic obstructive pulmonary disease (COPD) and has been linked with disease severity and impaired quality of life. Now, for the first time, researchers at the University of Pittsburgh have linked the systemic inflammation associated with COPD with depression in these patients.
“Systemic inflammation is thought to be an important mediator of comorbidities in COPD, but the relationship between inflammation and depression has not been explored,” said researcher Hilary Strollo, M.S., a graduate of the University of Pittsburgh School of Health and Rehabilitation Sciences. “In our study, we found a strong association between depressive symptoms and levels of the inflammatory biomarker interleukin-6 (IL-6) which was independent of the severity of airflow obstruction.”
The study results will be presented at the ATS 2013 International Conference in Philadelphia.
