Exploring Lithium: A Potential Disease-Modifying Therapy for Emphysema

While chronic obstructive pulmonary disease (COPD) remains a leading cause of death worldwide, there is still no treatment that reverses or halts its progression. Recent research is exploring the potential of lithium, a drug commonly used for bipolar disorder, as a candidate to repair lung damage by targeting a key regenerative signaling pathway in the lung.

This study is being led by Divay Chandra, MD, MSc, an associate professor in the Division of Pulmonary, Allergy, Critical Care, and Sleep Medicine, Department of Medicine, at University of Pittsburgh in Pennsylvania. Chandra spoke in the third issue of The Respiratory Report, a quarterly newsletter from HCPLive that is powered by the American Lung Association Research Institute, on his team’s current research in this area.

Chandra and his team analyzed data from large population cohorts to assess whether individuals taking lithium for other conditions had less lung disease and then measured environmental lithium exposure in people not on the drug. They found that both therapeutic and naturally occurring lithium levels were associated with reduced COPD severity, supporting its potential as a disease-modifying agent. The next step in Chandra's research is scaling up their studies to look at longitudinal progression and is enabled by an American Lung Association grant.

"Despite decades of research and multiple clinical trials, as yet, we have not been able to identify a disease modifying agent in COPD. And that is really the frustrating part. We have drugs that can treat symptoms. You know, we have drugs which can treat eosinophilia, which can reduce exacerbations, but we have no drug that can get at the fundamental disease process that drives this lung disease. That is exactly where lithium could play a role," Chandra said.
