Asthma across the lifespan: Time for a paradigm shift

Abstract

We have a unique opportunity to significantly reduce the worldwide burden of asthma in children and affect respiratory outcomes in adults. However, this will require a paradigm shift that is directed at altering the natural history of asthma, reducing asthma exacerbations, and preventing long-term adverse outcomes of childhood asthma. Attention should continue to be directed toward minimizing risk, as well as impairment, with a goal to achieve optimal control. Based on several National Institutes of Health studies conducted over the last 10years, we now have the tools necessary to accomplish this goal. The tools include assessment of lung function over time or defining trajectories of lung growth, the Composite Asthma Severity Index score, a panel of useful biomarkers, the Seasonal Asthma Exacerbation Prediction Index score, and rapidly advancing technology that includes adherence monitoring. Future guideline revisions should consider incorporating recommendations to follow spirometry over time and defining trajectories of lung growth to assess risk for reduced lung growth and early decline, asthma burden by using biomarkers to select and monitor therapy, assessment of social determinants of health, evaluation of risk for seasonal exacerbations, and consideration of electronic adherence monitoring for difficult-to-manage asthma. Guidelines should continue to include a core dedicated to the diagnosis and treatment of intermittent and mild and moderate persistent asthma and include additional sections dedicated to the management of severe asthma.
