National Asthma Education and Prevention Program (NAEPP) published its last Expert Panel Report in 2007. Since that time, substantial progress has been made in understanding the pathophysiology and treatment of asthma. A new report has provided a much-needed update in the evaluation and management of asthma. It focuses on several priority topics jointly decided upon by the National Heart, Lung, and Blood Institute (NHLBI) Advisory Council Asthma Expert Working Group, the National Asthma Education and Prevention Program (NAEPP) participant organizations, and the public in 2015. These topics include the role of fractional exhaled nitric oxide (FeNO), allergen mitigation, intermittent inhaled corticosteroids (ICS), long-acting muscarinic agents (LAMA), immunotherapy, and bronchial thermoplasty (BT) in asthma management. This document did not include the subsequent new developments in the role of biologics in asthma. The following is a summary of the recommendations made in the 2020 Focused Updates to the Asthma Management Guidelines.1
FeNO measurement is recommended to aid in asthma diagnosis and monitoring and to assist in ICS medication titration in individuals with asthma who are 5 years and older. The panel recommends that clinicians use FeNO levels, in conjunction with other relevant clinical data such as spirometry and asthma control questionnaires, for medical decision making. Similarly, when using FeNO to guide therapeutic changes in the ICS dose, the panel advises making changes based upon frequent measurements as a part of longitudinal assessment rather than one single measurement, as several factors can influence an FeNO measurement. Studies have demonstrated that a strategy that incorporates FeNO measurements into a treatment algorithm can reduce the risk of exacerbations; however, this has not been shown to reduce hospitalizations or quality of life.2
Allergen mitigation interventions, which can be used in individuals of all ages, are only recommended for those who have symptoms related to specific indoor aeroallergens exposure. This can be confirmed by skin testing or specific IgE in the appropriate clinical setting if specific allergen testing is not readily available. While most recommendations focus on using a multicomponent approach to allergen mitigation (ie, dust mite covers, HEPA filters, air purifiers, carpet removal, mold remediation, pest or pest removal, etc), pest removal was the only single-component approach that was deemed effective. Dust mite covers alone are unlikely to lead to significant improvement if not paired with additional mitigation strategies; however, note that there was low certainty about these recommendations. Ultimately, allergen mitigation should focus on addressing those identified triggers resulting in poor control of asthma. Simultaneously, the clinician should consider the resources and costs associated with some of these interventions.
The panel has recommended using ICS therapy for on-demand (prn) usage, even in those with mild persistent asthma, recognizing that earlier and more frequent on-demand ICS usage results in fewer exacerbations. While the recommendations slightly differ based upon the age group, in those >12 years with mild persistent asthma, recommendations are for either daily ICS + as-needed short-acting beta-agonist (SABA), or as-needed ICS and SABA use. As in the Global Initiative for Asthma (GINA) guidelines, the panel also recommends single maintenance and rescue therapy (SMART) using ICS-formoterol inhalers for moderate to severe asthma. SMART has also been shown to reduce the risk of exacerbation. The clinician needs to use ICS-LABA medications where formoterol is the LABA component due to its quick onset of action (within 5 minutes, hence allowing it to be used as a rescue). Shared decision-making must be utilized when considering cost, insurance formulary restrictions, and perhaps delayed insurer and pharmacy adoption of these guidelines, as patients are likely to use more than one canister in a month when utilizing SMART.3,4
LAMA is a pharmacologic class of long-acting inhaled bronchodilators. Guidelines addressed the role of LAMA in individuals aged 12 years and older. Three recommendations are made regarding the role of LAMA in this age group. In individuals with persistent, uncontrolled asthma while using ICS therapy, the guidelines recommend the addition of a LABA over LAMA therapy.5 LAMA can be added to ICS in individuals with uncontrolled asthma who cannot use LABA or are already on ICS-LABA maintenance therapy.
For those patients with mild to moderate allergic asthma, as defined by allergic sensitization via skin testing or in-vitro elevated serum IgE levels, the expert panel conditionally recommends subcutaneous immunotherapy (SCIT) as an adjunct treatment to standard pharmacotherapy. It is recommended only in those patients whose asthma remains controlled throughout initiation, build-up, and maintenance phases. SCIT should not be used for patients with severe asthma, and all attempts should be made to optimize asthma with standard therapy first. The risks and benefits of SCIT should be discussed with the specialist before starting therapy. Sublingual immunotherapy (SLIT) is not recommended for the treatment of asthma.
Regarding BT, the Expert Panel conditionally recommends against BT in individuals age 18 years and older with persistent asthma because of the small benefit to risk ratio and uncertain outcomes. Because there is a risk of worsening asthma control or inducing an exacerbation, it is advised that BT not be performed in individuals with an FEV <50%-60% or those with a history of life-threatening asthma. If BT is considered, it should be performed by an experienced specialist and should be done in conjunction with a clinical trial or registry to track its long-term safety and effectiveness.6 All efforts should be made to optimize asthma therapy and address comorbidities before pursuing BT.
This Expert Panel report provides a robust systematic review of the evidence that addresses key questions in the management of asthma. However, not providing any recommendations regarding the use of biologics was a significant gap. Further guidance regarding their role can be found in the GINA guidelines, and by the European Respiratory Society and American Thoracic Society, both of which were also published in 2020.7,8Dr. Adrish is Clinical Assistant Professor, Bronx Care Health System, New York; Dr. Patil is Assistant Professor, Department of Respiratory Sleep and Critical Care Medicine, Maharashtra University of Health Sciences (MUHS), India; Dr. Oberle is Assistant Professor of Medicine, Associate Medical Director, Duke Asthma, Allergy and Airway Center, Durham, NC.
