New Asthma Therapy May Permanently Relieve Asthma Symptoms

25 million Americans live with asthma and for 10% of them, inhaled corticosteroids and beta-agonists are not strong enough medications to keep them out of the hospital, an article in NPR’s Shots blog reports. But in 2010, the FDA approved a new procedure, called bronchial thermoplasty, as the first non-pharmaceutical treatment for asthma patients. The procedure permanently relieves asthma symptoms by delivering “heated zaps of energy that essentially burn off the outer layer of smooth muscle cells” so that there is not as much tissue blocking airways during constriction episodes. A study in the American Journal of Allergy and Clinical Immunology found “patients who underwent the procedure, which requires three sessions, saw the number of asthma attacks drop by a third, on average, and emergency room visits decline by 70 percent. They also lost far fewer days from work and school.”
