Mind the gaps: clinical trial concepts to address unanswered questions in aeroallergen immunotherapy-an NIAID/AHRQ workshop.
A joint AHRQ and National Institute of Allergy and Infectious Diseases (NIAAD) workshop was held to develop trial concepts that could improve the use and effectiveness of aeroallergen immunotherapy (AAIT). Four different expert groups were formed to propose different study designs. These study designs would create clinical trials of long duration and would need highly characterized patient populations.

Association of inhaled corticosteroids and long-acting beta-agonists as controller and quick relief therapy with exacerbations and symptom control in persistent asthma: a systematic review and meta-analysis.
The authors conducted a systematic review and meta-analysis of the effects of single maintenance and reliever therapy (SMART) in patients with persistent asthma. They found that in patients with persistent asthma, the use of single maintenance and reliever therapy compared with inhaled corticosteroids as the controller therapy (with or without a long-acting beta-agonist) and short-acting beta-agonists as the relief therapy was associated with a lower risk of asthma exacerbations.

Primary adherence to controller medications for asthma is poor.
The objective of this study was to compare real-world adherence, including both primary and secondary adherence, to the major controller regimens (inhaled corticosteroids (ICSs), leukotriene antagonists (LTRAs), or ICS/long-acting b-agonists (ICS/LABAs) in diverse, insured populations. It found that adherence to controller medications is poor and many patients do not ever fill prescriptions for controller medications. However, primary adherence to ICSs was better than to LTRAs and ICS/LABAs.

Effectiveness of interventions to teach metered-dose and diskus inhaler techniques. A randomized trial.
This study evaluated the relative effects of two different educational strategies (teach-to-goal instruction vs. brief verbal instruction) in adults hospitalized with asthma or chronic obstructive pulmonary disease. It concluded that, Acute care events were less common among teach-to-goal participants than brief intervention participants at 30 days (17 percent vs. 36 percent,), but not at 90 days.

Leukotriene-receptor antagonists versus placebo in the treatment of asthma in adults and adolescents: a systematic review and meta-analysis.
The purpose of this study was to determine the benefits and harms of leukotriene-receptor antagonists (LTRAs) as monotherapy or in combination with inhaled corticosteroids compared with placebo in adults and adolescents with asthma. It found that leukotriene-receptor antagonists as monotherapy improved asthma control compared with placebo, but which patients are most likely to respond to treatment with LTRAs remains unclear.

Anticholinergic vs long-acting beta-agonist in combination with inhaled corticosteroids in Black adults with asthma: the BELT randomized clinical trial.
The researchers compared the effectiveness and safety of tiotropium vs long-acting beta agonists (LABAs), when used with inhaled corticosteroids (ICS) in black adults with asthma. They found that among black adults with asthma treated with ICS, adding a LABA did not improve time to asthma exacerbation compared with adding tiotropium. These findings were not affected by polymorphisms at the Arg16Gly locus of ADRB2.

Patients' and providers' perceptions of asthma and asthma care: a qualitative study.
The primary goal of this qualitative study was to further explore patient and provider perceptions of asthma and asthma care as part of a larger Asthma Comparative Effectiveness Study. Three overarching themes, with a variety of subthemes, emerged as the main findings of this study. The three main themes were Cost/Economic Barriers/Process, Self-Governance/Adherence and Education.

Use of leukotriene receptor antagonists are associated with a similar risk of asthma exacerbations as inhaled corticosteroids.
The researchers compared the effectiveness of different controller medication regimens under real-life conditions. They found that the risk of emergency department visits, hospitalizations, and oral corticosteroids did not differ between children who initiated leukotriene antagonist and those who initiated inhaled corticosteroid. These findings may be explainable by leukotriene antagonist having similar effectiveness as inhaled corticosteroid in real-life usage.

A comparison of confounding adjustment methods for assessment of asthma controller medication effectiveness.
Using three confounding adjustment procedures—covariate-adjusted regression, propensity score regression, and high-dimemsional propensity score regression—on a population of 24,680 children with asthma, researchers found that patients treated with leukotriene antagonists were no more likely than those treated with inhaled corticosteroids to experience adverse outcomes.
