Head of the Copenhagen Prospective Studies on Asthma in Childhood
University of Copenhagen and Naestved Hospital
Medical Research: What is the background for this study?
Dr. Bisgaard: Childhood asthma is often preceded by recurrent asthma-like symptoms in relation to airway infections in the first years of life. Bacteria and viruses are equally associated with the risk of episodes of asthma-like symptoms in these children, suggesting antibiotics as a potential treatment for such episodes.
Medical Research: What are the main findings?
Dr. Bisgaard: Our study demonstrates a clinically significant shortening of symptom duration by 63% after intervention. The effect size increased with early initiation of treatment, showing a reduction in episode duration of 83% if treatment was initiated before day 6 of the episode. Azithromycin was effective in shortening the episodes even though no pathogenic bacteria was detected. This study is, to our knowledge, the first randomized trial of azithromycin treatment of acute episodes of asthma-like symptoms in young children with a history of recurrent episodes.
Medical Research: What should clinicians and patients take away from your report?
Dr. Bisgaard: Azithromycin reduced the duration of episodes of asthma-like symptoms in young children, suggesting that this drug could have a role in acute management of exacerbations. Further research is needed to disentangle the inflammatory versus antimicrobial aspects of this relation.
Medical Research: What recommendations do you have for future research as a result of this study?
Dr. Bisgaard: How the effect of azithromycin compares with narrow spectrum antibiotics and whether any long-term effects are associated with recurrent use need to be investigated. We are keenly aware of the potential ecological issues relating to use of antibiotics in terms of bacterial ecology and resistance. Future research should establish the choice of antimicrobial treatment and criteria for treatment, taking societal aspects into consideration.
MedicalResearch: Is there anything else you would like to add?
Dr. Bisgaard: Our data suggest an effect of azithromycin on acute asthma-like episodes and thereby identify a potential future treatment, but do not provide sufficient evidence to recommend this treatment in current clinical practice.
