Relief of Airflow Limitation and Airway Inflammation by Endoscopic Sinus Surgery in a Patient with Severe Asthma with Eosinophilic Chronic Rhinosinusitis

Although endoscopic sinus surgery (ESS) is beneficial in improving asthma symptoms, its impact on the lung function in patients with asthma and chronic rhinosinusitis remains unclear. We herein report a case of severe asthma with eosinophilic chronic rhinosinusitis, in which ESS substantially improved airflow limitation and concomitantly reduced fractional exhaled nitric oxide and blood eosinophil counts. ESS likely relieved airflow limitation by suppressing type 2 inflammatory pathways. This case highlights ESS as a promising strategy for achieving clinical remission in patients with severe asthma and chronic rhinosinusitis.

Severe Asthma Remissions Induced by Biologics Targeting IL5/IL5r: Results from a Multicenter Real-Life Study

Add-on biological therapy has proven to be effective in many patients with severe eosinophilic asthma. In this observational multicenter retrospective study, we report the results obtained with mepolizumab and benralizumab in severe asthmatics treated for 12 months in a real-life setting. In these patients, peripheral eosinophil levels, pulmonary function trends, exacerbation rates, systemic corticosteroid use, and symptom control were evaluated during the observation period, to understand which patients met all the criteria in order to be considered in disease remission. The percentage of remittent patients was 30.12% in the mepolizumab-treated subgroup, while in the benralizumab-treated subgroup, patients in complete disease remission were 40%, after 12 months. The results of this study confirm the efficacy of anti-IL-5 biologic drugs in the treatment of severe eosinophilic asthma in a real-life setting.

Enhancing the prediction of childhood asthma remission: Integrating clinical factors with microRNAs

The novel integration of baseline clinical and microRNA variables significantly improves the long-term individualized prediction of childhood asthma remission by early adulthood compared to using clinical variables alone.

The first year of treatment predicts the prognosis of asthma over 25 y-A prospective study

BACKGROUND

An investigator-driven, real-life follow-up study of adult-onset steroid-naïve, newly diagnosed asthma (162 patients) to investigate the treatment results over the 25-year course of the disease and whether the first treatment year's forced expiratory volume in one second (FEV₁ ) predicts the long-term prognosis.

METHODS

Eighty-three per cent of the 133 living patients participated in the 25-year examinations. At this visit, basic asthma examinations including lung function, as well as questionnaires for health-related quality of life (HRQoL), GINA and the Asthma Control Test, were used for evaluation. The use of medication and remission was verified.

RESULTS

There was no statistically significant change in mean FEV₁ % predicted (FEV₁ %) from baseline to the 25-year control. The changes in FEV₁ % during the first year predicted the results at the end of follow-up. Normal FEV₁ % at the end of the first year predicted normal FEV₁ , and below-normal FEV₁ % at 1 year predicted below-normal FEV₁ % at 25 years. Twenty-nine patients (26.4%) had discontinued their medication, and six (5.5%) used ICS periodically. Clinical remission was reached by 16.4% of the patients, and 7.6% reached functional remission. The general HRQoL remained unchanged.

CONCLUSION

In adult-onset asthma, the level of FEV₁ reached during the first treatment year seems to predict the later lung function level. One quarter of the patients discontinued the asthma treatment, but their HRQoL was better than that of those continuing to use ICS. Clinical remission was reached by 16% of the patients, which is in concordance with other studies.

Remission of persistent childhood asthma: Early predictors of adult outcomes

BACKGROUND

Few data exist on the predictors of asthma remission by early adulthood in North America.

OBJECTIVE

The predictors of adult asthma remission were determined in a multiethnic population of patients with mild-to-moderate persistent childhood asthma.

METHODS

Asthma remission in early adulthood was measured by using 2 definitions: a clinical and a strict definition. Both included normal lung function and the absence of symptoms, exacerbations, and medication use. The strict definition also included normal airways responsiveness. Predictors were identified from 23 baseline measures by using multivariate logistic regression. The probability of remission was modeled by using decision tree analysis.

RESULTS

In 879 subjects the mean ± SD baseline age was 8.8 ± 2.1 years, 59.4% were male, and 68.7% were white. By adulthood, 229 (26.0%) of 879 participants were in clinical remission, and 111 (15.0%) of 741 participants were in strict remission. The degree of FEV₁/forced vital capacity (FVC) ratio impairment was the largest predictor of asthma remission. More than half of boys and two thirds of girls with baseline FEV₁/FVC ratios of 90% or greater were in remission at adulthood. Decreased airways responsiveness was also a predictor for both remission definitions (clinical remission odds ratio, 1.23 [95% CI, 1.09-1.39]; strict remission odds ratio, 1.52 [95% CI, 1.26-1.84]). The combination of normal FEV₁/FVC ratio, airways responsiveness, and serum eosinophil count at baseline yielded greater than 80% probability of remission by adulthood.

CONCLUSION

A considerable minority of patients with persistent childhood asthma will have disease remission by adulthood. Clinical prognostic indicators of asthma remission, including baseline lung function, can be seen from an early age.
