Randomized Controlled Trial
Biomarker-guided management reduces exacerbations in non-eosinophilic asthma in pregnancy: A secondary analysis of a randomized controlled trial.
The aim of this secondary analysis of a randomized controlled trial (RCT) of asthma management in pregnancy was to determine the treatment decision differences between a symptom control algorithm and a fractional exhaled nitric oxide (FENO)-guided algorithm, and whether the approach was effective in non-eosinophilic asthma (NEA). ⋯ The FENO algorithm was more effective in treating NEA, resulting in reduced exacerbations, compared to a symptom control algorithm. This was not the result of ICS overtreatment, since the benefits occurred at a lower median daily ICS dose. Two applications of the FENO-guided algorithm, one month apart, were sufficient to achieve beneficial effects in terms of asthma exacerbations, among pregnant women with asthma.

Acute exacerbation (AE) is a severe complication of idiopathic pulmonary fibrosis (AE-IPF). In 2016, an international working group revised its definition and diagnostic criteria; however, few studies have assessed the frequency and prognosis of AE in patients with other fibrotic interstitial lung diseases (FILD). ⋯ All forms of ILD are at risk of AE and have a similar outcome to AE-IPF.
