Bronchial thermoplasty was found to be a safe, effective and durable treatment for severe asthma, suggests the findings of a recent study published in the Chest journal, conducted by Geoffrey Chupp and colleagues from the Yale University. The open-label, observational, multi-center study was conducted in the US and Canada where the researchers evaluated the hospitalisation, severe exacerbations, medication usage and ED visits of the patients. The research analysed 284 patients to find that the proportion of subjects on maintenance oral corticosteroids decreased from 19.4percent at baseline to 9.7 percent in 5 years. The researchers added that all subgroups demonstrated significant development, suggesting hopes for bronchial thermoplasty treatment for patients in the future.
