Conference focused on advancing excellence and innovation in pulmonary and critical care medicine

Miami (October 23, 2025) – The Bronchiectasis and NTM Association announced today that two abstracts using Bronchiectasis and NTM Research Registry data were presented at CHEST 2025, held October 19-22, 2025, in Chicago.

The abstracts are:

• “The Relationship Between Baseline Severity of Bronchiectasis and Incident Non-Tuberculous Mycobacterial Infection: findings from the U.S. Bronchiectasis and NTM Research Registry,” which examined whether increased bronchiectasis severity was associated with an increased risk of NTM infections.
• “The Impact of BMI in Bronchiectasis With or Without NTM: Findings From the US Bronchiectasis and NTM Research Registry (BRR),” which studied how BMI levels may impact outcomes in patients with bronchiectasis and if the presence of an NTM infection influenced those outcomes.

The Registry, an initiative of the Bronchiectasis and NTM Association, is a national database that collects clinical data from individuals diagnosed with non-cystic fibrosis (non-CF) bronchiectasis and nontuberculous mycobacterial (NTM) pulmonary disease. It includes participants from multiple clinical institutions across the United States to help support collaborative research and planning of multi-center clinical trials.

The Registry is supported by the Richard H. Scarborough Bronchiectasis Research Fund, the Anna-Maria and Stephen Kellen Foundation, a Research Grant from Insmed Incorporated, and the Bronchiectasis and NTM Industry Advisory Committee.

About Bronchiectasis and NTM Lung Disease

Bronchiectasis is a chronic lung disease characterized by enlarged airways that are thickened and/or scarred. These permanently widened airways lead to a buildup of mucus and impaired clearance of bacteria from the lungs. Between 340,000 and 522,000 adults are receiving treatment in the U.S.

Nontuberculous mycobacterial (NTM) lung disease is a chronic respiratory condition caused by certain types of mycobacteria commonly found in the environment, such as in soil and water. NTM lung disease predominantly affects individuals with compromised immune systems or pre-existing lung conditions, such as bronchiectasis and chronic obstructive pulmonary disease (COPD). NTM lung disease affects tens of thousands of individuals in the U.S. with rates of infection on the rise.

About the Bronchiectasis and NTM Association
The Bronchiectasis and NTM Association is a nonprofit organization whose mission is to improve the lives of people with bronchiectasis, nontuberculous mycobacterial lung (NTM) disease, or both conditions. The Association accomplishes this by providing education, supporting advocacy, furthering research, and advancing high-quality, specialized care. For more information, visit www.bronchandntm.org.
