Airway reversibility in asthma and phenotypes of Th2-biomarkers, lung function and disease control

Abstract Background High bronchodilator reversibility in adult asthma is associated with distinct clinical characteristics. In this study, we aim to make a comparison with T-helper 2 (Th2)-related biomarkers, lung function and asthma control between asthmatic patients with high airway reversibility (HR) and low airway reversibility (LR). Methods Patients with asthma diagnosed by pulmonologist according to Global Initiative for Asthma guidelines were recruited from the outpatient department of our hospital from August 2014 to July 2017. Patients were divided into HR and LR subgroups based on their response to bronchodilators of lung function (HR = Δforced expiratory volume in one second (FEV1) postbronchodilator ≥ 20%). Blood eosinophil count and serum IgE level, which are biomarkers of T-helper (Th)-2 phenotypes, were detected for patients. Asthma Control Test (ACT) was used to assess asthma control after the first-month initial treatment. Results A total of 265 patients with asthma were followed 1 month after initial treatment. HR group shows a higher level of Th2-high biomarkers (blood eosinophil count (10^9/L): 0.49 ± 0.28 vs 0.36 ± 0.19, P < 0.01; IgE (ng/ml): 1306 ± 842 vs 413 ± 261, P < 0.01), lower baseline lung function (FEV1%pred: 51.91 ± 19.34% vs 60.42 ± 19.22%, P < 0.01; forced expiratory flow (FEF)25–75: 0.76 ± 0.37 vs 1.00 ± 0.67, P < 0.01; FEF25–75%pred: 21.15 ± 10.09% vs 29.06 ± 16.50%, P < 0.01), and better asthma control (ACT score: 22 ± 4 vs 20 ± 4, P = 0.01) than LR group. HR was associated with a decreased risk of uncontrolled asthma after the first-month initial treatment (adjusted OR: 0.12 [95% confidence intervals: 0.03–0.50]). Conclusions HR is a physiologic indicator of lower lung function and severe small airway obstruction, and is more related with an increased level of Th2-biomarkers than LR. Moreover, HR may indicate controlled asthma after the first-month initial treatment. This finding may contribute to identification of asthma endotype

Assessing Resident Well-Being After the ABSITE: A Bad Time to Ask?

Objectives: Assess the association of residents' exam performance and transient emotions with their reports of burnout, suicidality, and mistreatment. Background: An annual survey evaluating surgical resident well-being is administered following the American Board of Surgery In-Training Examination (ABSITE). One concern about administering a survey after the ABSITE is that stress from the exam may influence their responses. Methods: A survey was administered to all general surgery residents following the 2018 ABSITE assessing positive and negative emotions (scales range from 0 to 12), as well as burnout, suicidality over the past 12 months, and mistreatment (discrimination, sexual harassment verbal/emotional or physical abuse) in the past academic year. Multivariable hierarchical regressions assessed the associations of exam performance and emotions with burnout, suicidality, and mistreatment. Results: Residents from 262 programs provided complete responses (N = 6987, 93.6% response rate). Residents reported high mean positive emotion (M = 7.54, SD = 2.35) and low mean negative emotion (M = 5.33, SD = 2.43). While residents in the bottom ABSITE score quartile reported lower positive and higher negative emotion than residents in the top 2 and 3 quartiles, respectively (P < 0.005), exam performance was not associated with the reported likelihood of burnout, suicidality, or mistreatment. Conclusions: Residents' emotions after the ABSITE are largely positive. Although poor exam performance may be associated with lower positive and higher negative emotion, it does not seem to be associated with the likelihood of reporting burnout, suicidality, or mistreatment. After adjusting for exam performance and emotions, mistreatment remained independently associated with burnout and suicidality. These findings support existing evidence demonstrating that burnout and suicidality are stable constructs that are robust to transient stress and/or emotions

Smoking Status Modifies the Relationship between Th2 Biomarkers and Small Airway Obstruction in Asthma

Background. Cigarette smoking and Th2-inflammation are both crucial in the pathogenesis of asthma. However, it is unknown whether smoking can affect the association between Th2-inflammation and small airway obstruction in adults with asthma. Methods. Adults diagnosed with asthma by a pulmonologist according to Global Initiative for Asthma guidelines were recruited from September 2016 to April 2018 to participate in this study. Participants were divided into two groups, the small airway obstruction group (those with FEF25–75% predicted value ≤ 65%) and the normal small airway function group (those with FEF25–75% predicted value > 65%). Final data analysis included 385 and 93 people in the Obstructive Group and the Normal Group, respectively. Total serum IgE level and blood eosinophil count were used as biomarkers of the Th2 phenotype. Results. The Obstructive Group had a larger fraction of smokers, higher blood eosinophil count, and lower lung function than the Normal Group. Current-smoking status was associated with an increased risk of small airway obstruction (adjusted odds ratio = 4.677, 95% confidence interval [1.593–13.730]); and log-IgE level was associated with a decreased risk of small airway obstruction (0.403 [0.216–0.754]). Smoking status stratified analysis showed an association between log-IgE level and a decreased risk of small airway obstruction only in never-smoker asthmatics (0.487 [0.249–0.954]). Conclusions. Current-smoking status and total serum IgE are, respectively, associated with small airway obstruction. Smoking status modifies the relationship between Th2 biomarkers and small airway function. These findings contribute to the understanding of risk factors associated with asthma endotyping
