About the Study

Research Center: Duke Health Pulmonary Division
Location: 2080 Duke University Road, Durham, NC 27708, USA
Lead Researcher: Dr. Loretta Georgina Que
IRB Committee: This study has been reviewed and approved by the Duke University Medical Center Institutional Review Board

Increased body weight is an asthma comorbidity that affects nearly 40% of those with asthma in the United States. Obesity and weight gain have been linked to increasing the severity of asthma. According to the National Asthma Survey, asthmatics who suffer from obesity are more likely to have continuous lung problems, experience more asthma exacerbations that require hospitalization.
Researchers are seeking new options to help those with asthma who also are struggling with weight. This study seeks to learn the effectiveness of a natural dietary supplement (L-citrulline) on decreasing lung inflammation.  L-citrulline is naturally found in the watermelon and is already available in the market at health food stores.

Interested participants must be 18 to 65 years old who are diagnosed with asthma and are struggling with weight. Participants must be willing to comply with the necessary study requirements.  Compensation will be available to eligible for their participation in this study.
