Drug repurposing is a major field of value-added medicine. It involves investigating and evaluating existing drugs for new therapeutic purposes that address unmet healthcare needs. Several unmet needs in allergic rhinitis could be improved by drug repurposing. This could be game-changing for disease management. Current medications for allergic rhinitis are centered on continuous long-term treatment, and medication registration is based on randomized controlled trials carried out for a minimum of 14 days with adherence of 70% or greater. A new way of treating allergic rhinitis is to propose as-needed treatment depending on symptoms, rather than classical continuous treatment. This rostrum will discuss existing clinical trials on as-needed treatment for allergic rhinitis and real-world data obtained by the mobile health app MASK-air, which focuses on digitally-enabled, patient-centered care pathways.

Biomarkers for the diagnosis, treatment and follow-up of patients with rhinitis and/or asthma are urgently needed. Although some biologic biomarkers exist in specialist care for asthma, they cannot be largely used in primary care. There are no validated biomarkers in rhinitis or allergen immunotherapy (AIT) that can be used in clinical practice. The digital transformation of health and health care (including mHealth) places the patient at the center of the health system and is likely to optimize the practice of allergy. Allergic Rhinitis and its Impact on Asthma (ARIA) and EAACI (European Academy of Allergy and Clinical Immunology) developed a Task Force aimed at proposing patient-reported outcome measures (PROMs) as digital biomarkers that can be easily used for different purposes in rhinitis and asthma. It first defined control digital biomarkers that should make a bridge between clinical practice, randomized controlled trials, observational real-life studies and allergen challenges. Using the MASK-air app as a model, a daily electronic combined symptom-medication score for allergic diseases (CSMS) or for asthma (e-DASTHMA), combined with a monthly control questionnaire, was embedded in a strategy similar to the diabetes approach for disease control. To mimic real-life, it secondly proposed quality-of-life digital biomarkers including daily EQ-5D visual analogue scales and the bi-weekly RhinAsthma Patient Perspective (RAAP). The potential implications for the management of allergic respiratory diseases were proposed.

Background: Validated combined symptom-medication scores (CSMSs) are needed to investigate the effects of allergic rhinitis treatments. This study aimed to use real-life data from the MASK-air® app to generate and validate hypothesis- and data-driven CSMSs. Methods: We used MASK-air® data to assess the concurrent validity, test-retest reliability and responsiveness of one hypothesis-driven CSMS (modified CSMS: mCSMS), one mixed hypothesis- and data-driven score (mixed score), and several data-driven CSMSs. The latter were generated with MASK-air® data following cluster analysis and regression models or factor analysis. These CSMSs were compared with scales measuring (i) the impact of rhinitis on work productivity (visual analogue scale [VAS] of work of MASK-air®, and Work Productivity and Activity Impairment: Allergy Specific [WPAI-AS]), (ii) quality-of-life (EQ-5D VAS) and (iii) control of allergic diseases (Control of Allergic Rhinitis and Asthma Test [CARAT]). Results: We assessed 317,176 days of MASK-air® use from 17,780 users aged 16-90 years, in 25 countries. The mCSMS and the factor analyses-based CSMSs displayed poorer validity and responsiveness compared to the remaining CSMSs. The latter displayed moderate-to-strong correlations with the tested comparators, high test-retest reliability and moderate-to-large responsiveness. Among data-driven CSMSs, a better performance was observed for cluster analyses-based CSMSs. High accuracy (capacity of discriminating different levels of rhinitis control) was observed for the latter (AUC-ROC = 0.904) and for the mixed CSMS (AUC-ROC = 0.820). Conclusion: The mixed CSMS and the cluster-based CSMSs presented medium-high validity, reliability and accuracy, rendering them as candidates for primary endpoints in future rhinitis trials.

It was aimed to reveal the continuing perfusion defect rates in patients with a diagnosis of pulmonary embolism (PE) due to COVID-19 who have completed the third month of anticoagulant therapy but whose symptoms or laboratory elevations continue.Patients with COVID-19 who were diagnosed with PE by Q-SPECT-CT between 1 September 2020 and 1 November 2021, who underwent control Q-SPECT/CT were included in the study. Demographic characteristics, laboratory findings, and first and second Q-SPECT/CT evaluation results of the patients were recorded.It was observed that the pulmonary defect continued in Q-SPECT/CT in the third month of anticoagulant treatment in 58.3% of the patients diagnosed with PE due to COVID-19, and new defects developed in 6.3%. The persistence rate of segment defects was higher than that of subsegment defects. It was observed that the defects persisted more frequently in patients with a history of hospitalization due to COVID-19.Perfusion defects may still be present in patients diagnosed with PE due to COVID-19 in the presence of persistent dyspnea/chest pain/D-dimer elevation after 3 months of treatment. Perfusion defect persistence rates are higher in defects more proximal to the subsegment level and in people with severe COVID-19, and extended treatment should be considered in these patients.

Obesity-associated asthma (OA) is a difficult to treat asthma phenotype due to its severity and poor response to inhaled steroids. Early-onset allergic (EoOA) and late-onset non-allergic (LoOA) OA are suggested subtypes of this phenotype. Natural Killer (NK) cells are key elements of innate immunity involved in cytotoxicity and immune regulation, with uncertain role in OA pathogenesis.Early-onset allergic and LoOA patients together with obese non-asthmatic (ONA) controls have been enrolled in the study. Peripheral blood samples have been collected for analysis. Percentages of total NK cells, CD3Results of ONA (n = 5, age 42 ± 8), EoOA (n = 5, age 42 ± 10) and LoOA (n = 8, age 46 ± 8) patients have analysed. Body Mass Index has been found to be negatively correlated with CD69 (p = .022, r = -0.534). NKG2D receptor has been significantly low in CD56Our study suggests an impaired NK receptor expression, activation and reduced cytotoxicity in OA patients together with variances between different subtypes of this phenotype. This data would be beneficial for tailoring a more personalized treatment strategy combatting steroid resistance and frequent exacerbations in this group of patients.

In order to understand the role of regular controller inhaled corticosteroids (ICS) versus as-needed ICS-formoterol in managing mild asthma, we performed a modified Delphi procedure.Opinions from 16 respiratory experts to three surveys and during a virtual scientific workshop helped to develop final consensus statements (pre-defined as 70% agreement).Thirteen participants completed all rounds (response rate 81%). At the end of the procedure, there was final consensus on: regular daily ICS being the recommended treatment approach in mild persistent asthma, with better symptom control and robust long-term clinical data compared with as-needed ICS-formoterol (85%); to avoid noncompliance, frequently seen in mild asthma patients, regular ICS dosing should be accompanied by ongoing education on treatment adherence (100%); treatment aims should be targeting asthma control (92%) and reduction of exacerbation risk (85%). No consensus was reached on whether GINA or national guidelines most influence prescribing decisions.It is important to encourage patients to be adherent and to target both asthma control and exacerbation risk reduction. There is robust clinical evidence to support proactive regular dosing with ICS controller therapy plus as-needed short-acting beta-agonists for the management of patients with mild asthma.

Introduction: National data on asthma characteristics and the factors associated with uncontrolled asthma seem to be necessary for every country. For this purpose, we developed the Turkish Adult Asthma Registry for patients with asthma aiming to take a snapshot of our patients, thereby assigning the unmet needs and niche areas of intervention. Methods: Case entries were performed between March 2018 and March 2022. A web-based application was used to record data. Study outcomes were demographic features, disease characteristics, asthma control levels, and phenotypes. Results: The registry included 2053 patients from 36 study centers in Turkey. Female subjects dominated the group (n = 1535, 74.8%). The majority of the patients had allergic (n = 1158, 65.3%) and eosinophilic (n = 1174, 57.2%) asthma. Six hundred nineteen (32.2%) of the patients had obese asthma. Severe asthma existed in 670 (32.6%) patients. Majority of cases were on step 3–5 treatment (n: 1525; 88.1%). Uncontrolled asthma was associated with low educational level, severe asthma attacks in the last year, low FEV1, existence of chronic rhinosinusitis and living in particular regions. Conclusion: The picture of this registry showed a dominancy of middle-aged obese women with moderate-to-severe asthma. We also determined particular strategic targets such as low educational level, severe asthma attacks, low FEV1, and chronic rhinosinusitis to decrease uncontrolled asthma in our country. Moreover, some regional strategies may also be needed as uncontrolled asthma is higher in certain regions. We believe that these data will guide authorities to reestablish national asthma programs to improve asthma service delivery.

Bacillus Calmette-Guerin vaccine is administered for protection against tuberculosis and may also have beneficial effects against some viral respiratory tract infections. In this study, it was aimed to investigate the relationship between Bacillus Calmette-Guerin vaccination which is confirmed by BCG scar, and the frequency and course of Coronavirus disease 2019 (COVID-19). Among 490 patients, 400 patients who accepted to participate in the study were included. After the consent of patients, age, gender, body mass index, comorbidities, smoking, history, and the progress of COVID-19 of these patients were investigated; the presence and number of Bacillus Calmette-Guerin scars were recorded by a physician. Data from groups with and without COVID-19 history were compared. There was no relation between presence and number of the BCG scar and COVID-19 related hospitalization and intensive care unit admission. When groups with and without COVID-19 history compared, no statistically significant difference was found with the presence and number of Bacillus Calmette-Guerin scars (P 0,05). No association was found between the presence or number of BCG scars and the frequency and course of COVID-19 in individuals with Bacillus Calmette-Guerin vaccination history confirmed by the presence of Bacillus Calmette-Guerin vaccine scars. Currently, the most important protection against COVID-19 is the COVID-19 vaccine.

Introduction: We aimed to evaluate clinical and laboratory findings of hospitalized asthma and chronic obstructive pulmonary disease (COPD) patients with COVID-19 and demonstrate that they have different symptoms and/or laboratory results and outcomes than COVID-19 patients with comorbidity (CoV-com) and without comorbidity (CoV-alone). Methodology: The data of the demographic, clinical, laboratory findings of hospitalized CoV-alone, asthma, COPD patients with COVID-19 (CoV-asthma, CoV-COPD, respectively), and CoV-com were analyzed. Results: Out of 1082 patients hospitalized for COVID-19, 585 (54.1%) had CoV-alone, 40 (3.7%) had CoV-asthma, 46 (4.3%) had CoV-COPD and 411 (38%) had CoV-com. Cough, shortness of breath, fever and weakness were the most common four symptoms seen in all COVID-19 patients. Shortness of breath, myalgia, headache symptoms were more common in CoV-asthma than the other groups (p < 0.001, p < 0.01, p < 0.05 respectively). Sputum was more common in CoV-COPD than other groups (p < 0.01). COPD group most frequently had increased values, different from the other groups with CRP>5ng/mL in 91.3%, D-dimer > 0.05mg/dL in 89.1%, troponin > 0.014micg/L in %63.9, INR>1.15 in 52.2%, CK-MB>25U/L in 48.5%, PT>14s in 40.9% of patients (p < 0.05, p < 0.001, p < 0.001, p < 0.001, p < 0.05, p < 0.001, respectively). NT-ProBNP was found to have the highest AUC value and the best differentiating parameter for CoV-asthma from CoV-alone. Typical CT findings were present in 44.4% of CoV-alone, 57.5% of CoV-asthma, 28.3% of CoV-COPD and 38.9% of CoV-com groups. CoV-COPD and CoV-com patients died more frequently than other groups (17.8%, 18.5%). Conclusions: CoV-asthma and CoV-COPD patients might have different symptoms and laboratory parameters than other COVID-19 patients which can guide the physicians.

The use of inhaler device (UID) and the satisfaction and adherence of patients to treatment were evaluated by Istanbul city community pharmacists to obtain real-life data from patients with asthma or chronic obstructive pulmonary disease (COPD).Pharmacists educated by pulmonary disease specialists asked patients who combined medications with inhaler devices to fill out a questionnaire prepared by the specialists. Each patient's UID was checked, and their errors were corrected by showing them the already prepared standard video of their inhaler device. Afterward, the UID was repeated and rechecked. The visual analog scale (VAS), feeling of satisfaction with the inhaler (FSI-10) questionnaire, and the Morisky Green Levine (MGL) scale were used for symptom control, satisfaction, and adherence, respectively. Then, we compared the results of three different types of inhalers: metered dose inhalers (MDI), dry powder inhalers (DPI), and dry powder inhalation capsules (DPI Caps).Twenty-seven (19.3%) patients used MDI, 42 (30%) used DPI caps, and 71 (50.7%) used DPI. UID before training was better in patients with DPI than in those with MDI and DPI Cap (The partnership between community pharmacists and pulmonary disease specialists improved patients' UID.

In clinical and epidemiological studies, cut-offs of Patient-Reported Outcome Measures (PROMs) can be used to classify patients into groups of statistical and clinical relevance. However, visual analog scale (VAS) cut-offs in MASK-air® have not been tested.To calculate cut-offs for VAS global, nasal, ocular, and asthma symptoms.In a cross-sectional study design of all MASK-air® participants, we compared (i) approaches based on the percentiles (tertiles or quartiles) of VAS distributions, and (ii) data-driven approaches based on clusters of data from two comparators (VAS work and VAS sleep). We then performed sensitivity analyses for individual countries and for VAS levels corresponding to full allergy control. Finally, we tested the different approaches using MASK-air® real-world cross-sectional and longitudinal data to assess the most relevant cut-offs.We assessed 395,223 days from 23,201 MASK-air® users with self-reported allergic rhinitis. The percentile-oriented approach resulted in lower cut-off values than the data-driven approach. We obtained consistent results in the data-driven approach. Following the latter, the proposed cut-off differentiating "controlled" and "partly-controlled" patients was similar to the cut-off value which had been arbitrarily used (20/100). However, a lower cut-off was obtained to differentiate between "partly-controlled" and "uncontrolled" patients (35 versus the arbitrarily-used value of 50/100).Using a data-driven approach, we were able to define cut-off values for MASK-air® VASs on allergy and asthma symptoms. This may allow for a better classification of rhinitis and asthma patients according to different levels of control, supporting improved disease management.

Patients with asthma often suffer from concomitant allergic rhinitis (AR). The Control of Allergic Rhinitis and Asthma Test (CARAT) is a validated tool to assess asthma and rhinitis multimorbidity. Turkish language validity and reliability of CARAT and its compatibility with other scales were evaluated in the study.Patients with asthma and concomitant AR were tested with CARAT. Pulmonary function tests, Asthma Control Test (ACT), Assessment Tool for Asthma (ATA) questionnaire and visual analogue scale (VAS) were also used at the same day. With the VAS, patients determined their rhinitis symptom levels, and asthma specialist determined the rhinitis and asthma control levels separately. These questionnaires were repeated in 14 ± 2 days.Three quarters (77%) of the 100 patients were female (mean age 46.5 years). The mean CARAT score was 19.6 ± 7.2. The Cronbach's alpha coefficient of the Turkish version of the CARAT scale was 0.83, showing a high level of internal consistency. Test-retest reliability coefficient was determined as r = 0.98 (p 0.001). The Kaiser-Meyer-Olkin coefficient of the CARAT scale was 0.79. The p value of the Bartlett test was0.001. ACT, ATA and VAS expert scales were correlated with CARAT total score (0.577 ≤ r ≤ 0.871). The CARAT scale did not show statistically significant difference according to gender, education, working status, smoking status, presence of polyps and multiple allergen sensitivity (p 0.05).The Turkish version of the CARAT is a reliable alternative tool for physicians in determining disease control in adult patients with asthma and AR.

Background: Different treatments exist for allergic rhinitis (AR), including pharmacotherapy and allergen immunotherapy (AIT), but they have not been compared using direct patient data (i.e., “real-world data”). We aimed to compare AR pharmacological treatments on (i) daily symptoms, (ii) frequency of use in co-medication, (iii) visual analogue scales (VASs) on allergy symptom control considering the minimal important difference (MID) and (iv) the effect of AIT. Methods: We assessed the MASK-air® app data (May 2015–December 2020) by users self-reporting AR (16–90 years). We compared eight AR medication schemes on reported VAS of allergy symptoms, clustering data by the patient and controlling for confounding factors. We compared (i) allergy symptoms between patients with and without AIT and (ii) different drug classes used in co-medication. Results: We analysed 269,837 days from 10,860 users. Most days (52.7%) involved medication use. Median VAS levels were significantly higher in co-medication than in monotherapy (including the fixed combination azelastine-fluticasone) schemes. In adjusted models, azelastine-fluticasone was associated with lower average VAS global allergy symptoms than all other medication schemes, while the contrary was observed for oral corticosteroids. AIT was associated with a decrease in allergy symptoms in some medication schemes. A difference larger than the MID compared to no treatment was observed for oral steroids. Azelastine-fluticasone was the drug class with the lowest chance of being used in co-medication (adjusted OR = 0.75; 95% CI = 0.71–0.80). Conclusion: Median VAS levels were higher in co-medication than in monotherapy. Patients with more severe symptoms report a higher treatment, which is currently not reflected in guidelines. publishersversion published

Purpose In order to determine the clinical and sociodemographic characteristics of newly diagnosed treatment-naive asthma and COPD patients in Turkey, a multicenter study in 2012 was initiated . We aimed to investigate the characteristics and therapies of COPD patients in the original study in more detail. Patients and methods This nation-wide, multicentric, non-interventional, prospective, real-life observational cohort study was conducted in 122 centers. The newly diagnosed patients were not receiving any treatment before the recruitment. Their general characteristics, the combined GOLD 2011 COPD categories and exacerbation histories were noted. The patients were followed up with 3 voluntary visits for 1 year. Their adherence to the inhaled treatment according to GOLD 2011 was evaluated during follow-up visits. Results The study included 776 COPD patients. Their mean age was 59.4±9.1 years, and 11.9% of the patients were female. 35.1% of the patients were in the GOLD 2011 C and D category. 12.6% are frequent exacerbators, and 52.8% had at least one comorbid condition. 71.8% overtreatment rate was detected. Their attendance rates for three follow-up visits became 55.9%, 32.9% and 18.7%, respectively. The adherence rate to the treatment was measured as 81.9%. Conclusion Although these patients were diagnosed for the first time, the GOLD C and D categories and frequent exacerbator phenotype were found at a high rate. They were usually prescribed an overtreatment regimen. We think that newly diagnosed COPD patients should be evaluated carefully, and best effort should be made to treat these patients in accordance with the recommendations of the major COPD guidelines.

Tezepelumab is a human monoclonal antibody that blocks the activity of thymic stromal lymphopoietin. SOURCE evaluated the oral corticosteroid-sparing effect of tezepelumab in adults with oral corticosteroid-dependent asthma.We conducted this phase 3, multicentre, randomised, double-blind, placebo-controlled study across 60 sites in seven countries. Participants aged 18-80 years with physician-diagnosed asthma, who had been receiving medium-dose or high-dose inhaled corticosteroids and had at least one asthma exacerbation in the 12 months before screening were eligible. Patients who were receiving medium-dose inhaled corticosteroids must have had their dose increased to a high dose for at least 3 months before screening. After an oral corticosteroid optimisation phase of up to 8 weeks, participants were randomly assigned according to a computer-generated fixed block randomisation sequence to receive tezepelumab 210 mg or placebo subcutaneously every 4 weeks during a 48 week treatment period (4 week induction phase, 36 week oral corticosteroid reduction phase, and 8 week maintenance phase). Randomisation was stratified by region. Participants, investigators, and site staff were masked to treatment assignment. The primary endpoint was the categorised percentage reduction from baseline in daily oral corticosteroid dose at week 48 without the loss of asthma control. Efficacy and safety endpoints were assessed in all participants who received at least one dose of study drug. This study is registered with ClinicalTrials.gov, NCT03406078.Between March 5, 2018, and Sept 27, 2019, 150 participants were randomly assigned to receive tezepelumab 210 mg (n=74) or placebo (n=76). The cumulative odds of achieving a category of greater percentage reduction in an oral corticosteroid dose for daily maintenance at week 48 were similar with tezepelumab or placebo in the overall population (odds ratio [OR] 1·28 [95% CI 0·69-2·35], p=0·43; the primary endpoint was not met). The cumulative odds were higher with tezepelumab than with placebo in participants with baseline blood eosinophil counts of at least 150 cells per μL (2·58 [1·16-5·75]), but not in participants with counts below 150 cells per μL (0·40 [0·14-1·13]). Tezepelumab was well tolerated, with no safety concerns identified. 53 (72%) of 74 tezepelumab-assigned participants and 65 (86%) of 76 placebo-assigned participants reported an adverse event. Serious adverse events were reported in 12 (16%) participants in the tezepelumab group and 16 (21%) participants in the placebo group.We did not observe a significant improvement in oral corticosteroid dose reduction with tezepelumab versus placebo in the overall population of this oral corticosteroid-sparing study, although an improvement was observed in participants with baseline blood eosinophil counts of at least 150 cells per μL.AstraZeneca and Amgen.

Background: Several studies have suggested an impact of allergic rhinitis on academic productivity. However, large studies with real-world data (RWD) are not available. Objective: To use RWD to assess the impact of allergic rhinitis on academic performance (measured through a visual analog scale [VAS] education and the Work Productivity and Activity Impairment Questionnaire plus Classroom Impairment Questions: Allergy Specific [WPAI+CIQ:AS] questionnaire), and to identify factors associated with the impact of allergic rhinitis on academic performance. Methods: We assessed data from the MASK-air mHealth app of users aged 13 to 29 years with allergic rhinitis. We assessed the correlation between variables measuring the impact of allergies on academic performance (VAS education, WPAI+CIQ:AS impact of allergy symptoms on academic performance, and WPAI+CIQ:AS percentage of education hours lost due to allergies) and other variables. In addition, we identified factors associated with the impact of allergic symptoms on academic productivity through multivariable mixed models. Results: A total of 13,454 days (from 1970 patients) were studied. VAS education was strongly correlated with the WPAI+CIQ:AS impact of allergy symptoms on academic productivity (Spearman correlation coefficient = 0.71 [95% confidence interval (CI) = 0.58; 0.80]), VAS global allergy symptoms (0.70 [95% CI = 0.68; 0.71]), and VAS nose (0.66 [95% CI = 0.65; 0.68]). In multivariable regression models, immunotherapy showed a strong negative association with VAS education (regression coefficient = -2.32 [95% CI = -4.04; -0.59]). Poor rhinitis control, measured by the combined symptom-medication score, was associated with worse VAS education (regression coefficient = 0.88 [95% CI = 0.88; 0.92]), higher impact on academic productivity (regression coefficient = 0.69 [95% CI = 0.49; 0.90]), and higher percentage of missed education hours due to allergy (regression coefficient = 0.44 [95% CI = 0.25; 0.63]). Conclusion: Allergy symptoms and worse rhinitis control are associated with worse academic productivity, whereas immunotherapy is associated with higher productivity.

Objective: Treatment adherence, asthma control, inhaler satisfaction, and quality of life of patients with asthma were investigated to examine whether there were any differences between conventional fixed combined therapy and maintenance and reliever therapy after inhaler education.Methods: Cross-sectional observational follow-up of 120 patients with asthma receiving third- and fourth-step treatment was completed at zero, three, and six months. Fifty-eight patients received long-acting beta-agonists or inhaler corticosteroids (ICS) as maintenance therapy and short-acting beta-agonists (SABA) as reliever therapy (CONV) with Diskus and Ellipta devices. Sixty-two patients received ICS/formoterol as maintenance and reliever therapy (MART) with metered-dose inhaler and Turbuhaler devices. The asthma control test (ACT), feeling of satisfaction with the inhaler (FSI-10) questionnaire, Morisky Green Levine (MGL) scale, and quality of life questionnaire (AQLQ) were evaluated at each visit.Results: Significant improvement was observed in the ACT, AQLQ, FSI-10, MGL scales, and inhaler technique in both groups over time (p < 0.05). There was no difference in the MGL scale between the groups at all visits. Nonadherence was highest in the Diskus device group (55%) and lowest in the Ellipta device group at the first visit (25%). While 36% of the patients had low adherence at the first visit, this decreased to 12% by the last visit. A significant correlation was found between ACT and MGL at all visits (p < 0.001).Conclusion: Asthma control, adherence, inhaler satisfaction, and quality of life improved equally with regular follow-up and standard inhaler education in the CONV and MART groups.

Objective Exposure to cigarette smoke complicates the treatment and management of asthma through a variety of inflammatory effects. This study aimed to investigate the differences between newly diagnosed cases of asthma in smokers and nonsmokers in terms of localized and systemic biomarkers following treatment with inhaled corticosteroids (ICS) or ICS in combination with a long-acting beta 2 agonist (LABA). Methods Specimens of exhaled breath condensate (EBC) from newly diagnosed patients with asthma were used to quantify inflammation in the airways, while blood samples were used to assess systemic inflammation. In both samples, the levels of IL-6, LTB4, LTD4, and 8-isoprostane were measured and these were repeated after 3 months of treatment with ICS or ICS + LABA. Results Of the 20 patients, 10 (50%) were nonsmokers with asthma (NSA) and 10 (50%) smokers with asthma (SA). There was no statistically significant difference in the blood or EBC levels of IL-6, LTB4, LTD4, or 8-isoprostane between the groups prior to treatment. Only the decrease in 8-isoprostane level in the EBC samples was found to be significantly greater in the NSA group after treatment (for smokers, the change was 2.91 +/- 23.22, while for nonsmokers it was -22.72 +/- 33.12, p = 0.022). Post-treatment asthma control was significantly better in the NSA group (p = 0.033). Conclusion Monitoring the alterations in 8-isoprostane levels in EBC in patients with asthma who smoke may be helpful in deciding on therapeutic management and switching treatments. Asthma control was better in nonsmokers than in smokers.

Background Although there are many asymptomatic patients, one of the problems of COVID-19 is early recognition of the disease. COVID-19 symptoms are polymorphic and may include upper respiratory symptoms. However, COVID-19 symptoms may be mistaken with the common cold or allergic rhinitis. An ARIA-EAACI study group attempted to differentiate upper respiratory symptoms between the three diseases. Methods A modified Delphi process was used. The ARIA members who were seeing COVID-19 patients were asked to fill in a questionnaire on the upper airway symptoms of COVID-19, common cold and allergic rhinitis. Results Among the 192 ARIA members who were invited to respond to the questionnaire, 89 responded and 87 questionnaires were analysed. The consensus was then reported. A two-way ANOVA revealed significant differences in the symptom intensity between the three diseases (p < .001). Conclusions This modified Delphi approach enabled the differentiation of upper respiratory symptoms between COVID-19, the common cold and allergic rhinitis. An electronic algorithm will be devised using the questionnaire.

Background/aim We aimed to report outcomes of pregnant patients with asthma under omalizumab treatment and their infants in our country. Materials and methods Patients with asthma who received omalizumab for at least 6 months and at least one dose during their pregnancy were retrospectively evaluated using a questionnaire regarding their disease and therapy and the health of their infants. Results Twenty pregnant patients and their 23 infant’s data were analyzed. The mean delivery age was 31.8 ± 7.4 years. They received omalizumab for 28.9 ± 21.8 months. Eight (36.4%) patients showed exacerbation of the disease during pregnancy. Forced expiratory volume in 1 s (FEV1) and asthma control test (ACT) scores at the starting time of omalizumab administration, first month of the pregnancy, and after delivery were 71 ± 18%, 83.4 ± 10.5%, and 80.5 ± 13% (FEV1), and 11.9 ± 4.9, 20.2 ± 2.6, and 20.4 ± 2.2 (ACT), respectively. One patient gave birth to twin infants, two patients to two infants each in different years, and 17 to one infant each. Three (13%) infants had low birth weight and five (21.7%) were born prematurely. No congenital anomalies were detected. Seven (30.4%) infants presented atopic diseases during their life. Conclusion Omalizumab treatment during pregnancy seems to be safe for both patients and their infants.

International audience; In this article, we propose that differences in COVID-19 morbidity may be associated with transient receptor potential ankyrin 1 (TRPA1) and/or transient receptor potential vanilloid 1 (TRPV1) activation as well as desensitization. TRPA1 and TRPV1 induce inflammation and play a key role in the physiology of almost all organs. They may augment sensory or vagal nerve discharges to evoke pain and several symptoms of COVID-19, including cough, nasal obstruction, vomiting, diarrhea, and, at least partly, sudden and severe loss of smell and taste. TRPA1 can be activated by reactive oxygen species and may therefore be up-regulated in COVID-19. TRPA1 and TRPV1 channels can be activated by pungent compounds including many nuclear factor (erythroid-derived 2) (Nrf2)-interacting foods leading to channel desensitization. Interactions between Nrf2-associated nutrients and TRPA1/TRPV1 may be partly responsible for the severity of some of the COVID-19 symptoms. The regulation by Nrf2 of TRPA1/TRPV1 is still unclear, but suggested from very limited clinical evidence. In COVID-19, it is proposed that rapid desensitization of TRAP1/TRPV1 by some ingredients in foods could reduce symptom severity and provide new therapeutic strategies.

Objective: Natural killer cells play immunomodulatory role the pathogenesis of chronic inflammatory airway diseases. NK cells may induce allergic airway inflammation by increasing the production of type 2 cytokines. Materials and Methods: Intracytoplasmic cytokine levels of IL-13, IL-4 IFN-gamma and IL-10 in NK cells and plasma levels of IFN-gamma, TNF-alpha., IL-2, IL-8, IL-4, IL-5, IL-6, IL-17,IL-12, IL-13, IL-1 beta and IL-10 in patients with newly diagnosed asthma, asthmatic patients under treatment and controls by using flow cytomeny and Procartallex multiplex immunoassays kit were measured. Results: The numbers of IFN-gamma(+) NKI cells were decreased in both patient groups: comparing both asthmatic groups. IFN-gamma(+) NK1 cells were higher in asthmatic patients under treatment. Intracellular IL-4 levels of NK cells were increased, however IL-10(+) NK cells were diminished in both patient groups vs. controls. Increased number of IL-13(+) NK2 cells in newly-diagnosed asthmatics vs. asthmatics patients under treatment and controls were obtained. Increased levels of plasma IL-1 beta levels in newlydiagnosed asthmatic patients compared to that of asthmatics under treatment were found. Newly-diagnosed asthmatics showed higher IL-beta levels compared to asthmatics under treatment and controls. Increased IL -5 levels were measured in newly-diagnosed asthmatic patients compared to healthy subjects and higher IL-13 levels were detected in newly-diagnased asthmatic patients vs. other groups and also in controls vs. patients with asthma patients under treatment. IL-10 and IL-12 levels were decreased in newlydiagnosed asthmatic patients compared to healthy subjects. Compared to healthy subjects in both asthmatic patients' also diminished IL-2 levels were obtained. Conclusion: In order to use NK cells as a therapeutic target, a strategy must be established to regulate its cytokine secretion functions with respect to their role of these cells in each disease.

BackgroundOne-fifth of COVID-19 patients are seriously and critically ill cases and have a worse prognosis than non-severe cases. Although there is no specific treatment available for COVID-19, early recognition and supportive treatment may reduce the mortality. The aim of this study is to develop a functional nomogram that can be used by clinicians to estimate the risk of in-hospital mortality in patients hospitalized and treated for COVID-19 disease, and to compare the accuracy of model predictions with previous nomograms.MethodsThis retrospective study enrolled 709 patients who were over 18 years old and received inpatient treatment for COVID-19 disease. Multivariable Logistic Regression analysis was performed to assess the possible predictors of a fatal outcome. A nomogram was developed with the possible predictors and total point were calculated.ResultsOf the 709 patients treated for COVID-19, 75 (11%) died and 634 survived. The elder age, certain comorbidities (cancer, heart failure, chronic renal failure), dyspnea, lower levels of oxygen saturation and hematocrit, higher levels of C-reactive protein, aspartate aminotransferase and ferritin were independent risk factors for mortality. The prediction ability of total points was excellent (Area Under Curve = 0.922).ConclusionsThe nomogram developed in this study can be used by clinicians as a practical and effective tool in mortality risk estimation. So that with early diagnosis and intervention mortality in COVID-19 patients may be reduced.
