Brief Summary
Asthma is a chronic lung disease that affects millions of people worldwide, including both children and adults. The cause of asthma is not known, but asthma is strongly associated with inflammation of the airways, often caused by allergies. In order to control this inflammation, most people with asthma are treated with inhaled medications that contain steroids. These medications do a good job of helping most people with asthma feel better. However, these medications are expensive, have side effects, and do not control symptoms in all people with asthma. Recently basic science research colleagues have shown that inflammation due to allergies can be reduced in experimental animals by a naturally occurring bile acid. Bile acids are chemicals made in the liver that are involved in maintaining healthy digestion of fat. Since bile acids are made by our bodies, they have become popular as over the counter supplements that are thought to be important in promoting a healthy liver and metabolism. Interestingly, other research has shown that bile acids may help patients with neurological disease and diabetes. Given all of this information, the investigators propose that a specific bile acid called tauroursodeoxycholic acid (TUDCA) may be helpful in patients with asthma. Before studying this in a clinical trial, the current study is designed to demonstrate that people with asthma can take TUDCA safely and that it doesn't hurt their asthma. The study will involve inviting 12 patients with mild asthma to take TUDCA daily for 12 weeks. During this time the investigators will closely monitor them for any side effects and check their blood and breathing capacity for any signs of detrimental effects. In addition, the investigators will collect cells that line the nose, which are thought to be similar to cells in the airways of the lungs, to see if TUDCA is having any beneficial effects on inflammation. In order to ensure the use of high quality TUDCA, which may or may not be true of over the counter supplements, the investigators have asked the company that is supplying TUDCA for the studies mentioned previously involving neurological disease and diabetes to supply the drug; the brand name is Taurolite. In addition, even though TUDCA is available over the counter, in order to use it for research, the FDA has to approve this use. Accordingly, the investigators have applied for and received permission (IND) from the FDA to use Taurolite for this study.
