We investigated how physicians taking care of severe asthma patients in Europe reorganised care, and how these changes affected patient satisfaction, asthma control and future care.MethodsIn this European-wide cross-sectional study, patient surveys were sent to patients with a physician-diagnosis of severe asthma, and physician surveys to severe asthma specialists between November 2020 and May 2021.Results1101 patients and 268 physicians from 16 European countries contributed to the study. Common physician-reported changes in severe asthma care included use of video/phone consultations (46%), reduced availability of physicians (43%) and change to home-administered biologics (38%). Change to phone/video consultations was reported in 45% of patients, of whom 79% were satisfied or very satisfied with this change. Of 709 patients on...

Availability of real-life data about the clinical course of severe asthma is insufficient. Objectives: The aims of this study were to characterize patients with severe asthma in Switzerland, enrolled in the Swiss Severe Asthma Registry (SSAR), and evaluate predictors for asthma control. Method: A descriptive characterisation of 278 patients was performed, who were prospectively enrolled in the registry until January 2022. Socio-demographic variables, comorbidities, diagnostic values, asthma treatment, and healthcare utilisation were evaluated. Groups of controlled and uncontrolled asthma according to the asthma control test were compared. Results: Forty-eight percent of patients were female and the mean age was 55.8 years (range 13–87). The mean body mass index (BMI) was 27.4 kg/m2 (±6). 10.8%...

Vitamin D metabolites play an important role in the initiation of the immune response and can be an easily modifiable risk factor in 25-hydroxyvitamin D3 (25(OH)D3)-deficient patients. This is a multicenter, randomized, placebo-controlled double-blind trial to compare the effect of a single high dose of vitamin D3 followed by treatment as usual (TAU) of daily vitamin D3 daily until discharge versus placebo plus TAU in hospitalized patients with COVID-19 and 25(OH)D3-deficiency on length hospital stay. We included 40 patients per group and did not observe a significant difference in the median length of hospital stay (6 days in both groups, p = 0.920). We adjusted the length of stay for COVID-19 risk factors (β = 0.44; 95% CI: −2.17–2.22), and center (β = 0.74; 95% CI: −1.25–2.7...

This indicates the need for alternative strategies to prevent respiratory complications like acute respiratory distress system (ARDS) associated with COVID-19. Aviptadil, a synthetic form of Human Vasoactive Intestinal Peptide, might be beneficial for COVID-19 patients at high risk of developing ARDS because of its ability to influence the regulation of exaggerated pro-inflammatory proteins and orchestrating the lung homeostasis. Aviptadil has recently been shown to considerably improve the prognosis of ARDS in COVID-19 when applied intravenously. An inhaled application of Aviptadil has the advantages of achieving a higher concentration in the lung tissue, fast onset of activity, avoiding the hepa...

Factors associated with a worse Covid-19 prognosis include old age (> 65 years), ethnicity, male sex, obesity and people with comorbidities such as hypertension, diabetes, cardiovascular disease, and respiratory diseases. Further, vitamin D deficiency has been reported to be a predictor of poor prognosis in patients with acute respiratory failure due to Covid-19. Vitamin D deficiency is a modifiable risk factor, which - according to a recent clinical case series – has the prospect of reducing hospital stay, intensive care and fatal outcomes. Vitamin D has potent immunomodulatory property sand its supplementation might improve important outcomes in critically ill and vitamin D deficient Covid-19 patients. Despite the evidence that supports an association between vitamin D deficiency and Covid-19 severity, there is uncertainty about the direct link....

Mepolizumab has shown clinical efficacy in randomised controlled trials and prospective real-world studies and could therefore serve as a proof of principle for this novel approach. The aim of the present study was to harmonise data from 10 national severe asthma registries and characterise patients receiving mepolizumab, assess its effectiveness on annual exacerbations and maintenance oral glucocorticoid (OCS) use, and evaluate treatment patterns.MethodsIn this observational cohort study, registry data (5871 patients) were extracted for harmonisation. Where harmonisation was possible, patients who initiated mepolizumab between 1 January 2016 and 31 December 2021 were examined. Changes of a 12-month (range 11–18 months) period in frequent (two or more) exacerbations, maintenance...
