Internet monitoring strategy effective for severe asthma patients

Washington, May 17 (ANI): A new research from the Netherlands found that patients with severe asthma who use an internet-supported strategy and daily monitoring of exhaled nitric oxide (FENO) were able to control their asthma with lower overall dosing of oral corticosteroids (OCS) than patients who underwent usual care.

"We know that in patients with prednisone-dependent asthma it is important to adjust the daily dose of oral corticosteroids to the lowest possible level in order to reduce long-term side effects," said Simone Hashimoto, research fellow from the department of respiratory medicine of the University of Amsterdam.

"Our study shows that a novel internet-supported strategy including daily measurements of an objective marker of airway inflammation, FENO, and supervision by an asthma nurse allows frequent adjustments of prednisone dose, and leads to significant reduction of total corticosteroid consumption over a six months study period, as compared with patients receiving usual care. This was not accompanied by deterioration of asthma control or asthma-related quality of life."

The findings were presented at the ATS 2010 International Conference in New Orleans.

Dr. Hashimoto and colleagues designed a prospective, randomized, parallel, multicenter study with 89 patients with severe asthma study to test the hypothesis that a new internet-based strategy including daily home monitoring of symptoms, lung function, FENO, and regular feedback by an internet asthma nurse, would lead to a significant reduction of corticosteroid consumption without worsening of asthma control or asthma-related quality of life.

In total, 89 patients were randomized to two tapering strategies: sual care, or internet-supported with daily monitoring of FENO, FEV1 and symptoms.

For those assigned to the internet-supported strategy, each patient had a password used to log in to a secure site where they recorded daily symptoms, lung function values, FENO value and dose of medicine that they took in the day. The values were controlled every day by a specialized asthma nurse and once a week patients received instructions about the dose of oral corticosteroids they should use.

The process took about 5 minutes per day for the patient, and was well accepted. Patients could also contact the asthma nurse via the website or email in the event of questions or problems.

The researchers found that among patients assigned to the internet-supported strategy, cumulative 6-month dosing of OCS was significantly lower.

"Of course, we hoped to find a positive result, because Internet based self-management and management guidance by FENO has already been proven to be successful in adolescents with milder forms of asthma," said Dr. Hashimoto.

"However, we were surprised that also in patients with severe prednisone-dependent asthma this strategy proved to be successful. These patients have years of continuous use of oral corticosteroids and a long history of attempts to taper their maintenance prednisone dose without success. This strategy gives them new hope that they can safely reduce the deleterious long-term side effects of prednisone.

"Our findings suggest that this novel internet-based strategy can and should be applied in all patients with severe prednisone dependent asthma to reduce total corticosteroid consumption. Internet technologies as well as biomarker driven therapies will become more and more common in future health care.

"In the future, we will do more studies on a larger scale, to evaluate whether this strategy should be incorporated in guidelines for management of patients with severe asthma," Dr. ashimoto added. (ANI)
