    (Turkish Assoc Tuberculosis & Thorax, 2016) Celebi Sozener, Zeynep; Misirligil, Mehmet; Cerci, Pamir; Aydin, Omur; Kendirlinan, Resat; Sin, Betul; Misirligil, Zeynep
    Introduction: It is known that viral infections trigger exacerbations in asthma patients. There are conflicting reports on whether influenza vaccine is preventive or not. In this study, we aimed to evaluate asthmatic patient's attitude towards influenza vaccine and to determine which factors affect this attitude. Materials and Methods: A questionnaire involving data about demographic information, co-morbidities, frequency of viral upper respiratory tract infections, subject's influenza vaccination status and attitude towards vaccination had been filled for our outpatient clinic asthma patients and also for healthy controls. Results were evaluated separately for the two groups and then compared to each other. Results: For the study; 108 asthma patients (91 female, 17 male) and 110 non-asthmatic controls (64 female, 46 male) were enrolled. In asthma group, vaccination rates were significantly higher in the previous year (40.7%) and nearly half of them stated that they do regularly have influenza shots every year. Contrast to this find; half of the patients in the control group stated that they do not need to vaccinate themselves and 26.2% said that they don't believe influenza vaccine has any preventive effect. Also in the asthma group, this ratio was similar to the control group (20.3%). In asthma group, 66.7% of the patients who had side effects at their previous shots did not want to vaccinate themselves this year (p= 0.02). More than a half of the patients (53.1%) whom did not have shots had an episode of viral upper respiratory tract infection this year and this rate was significantly lower in the vaccinated group (p= 0.00). This result highlights the preventive effect of vaccination. Conclusion: We found that asthma patients' knowledge on influenza infection and vaccine were insufficient and also their belief towards the preventive features of the vaccination was low. Informing and encouraging patients about preventive medicine through various activities and meetings would be crucial.

    Inhaler Steroid Use Changes Oral and Airway Bacterial and Fungal Microbiome Profile in Asthma Patients
    (Karger, 2024) Oguzulgen, Kivilcim; Ozturk, Ayse Bilge; Bacceoglu, Ayse; Aydin, Omur; Koeycue Buhari, Gozde; Damadoglu, Ebru; Oner Erkekol, Ferda
    Introduction: The full spectrum of bacterial and fungal species in adult asthma and the effect of inhaled corticosteroid use is not well described. The aim was to collect mouthwash and induced sputum samples from newly diagnosed asthma patients in the pretreatment period and in chronic asthma patients while undergoing regular maintenance inhaled corticosteroid therapy, in order to demonstrate the bacterial and fungal microbiome profile. Methods: The study included 28 asthmatic patients on inhaler steroid therapy, 25 steroid-naive asthmatics, and 24 healthy controls. Genomic DNA was isolated from induced sputum and mouthwash samples. Analyses were performed using bacterial primers selected from the 16S rRNA region for the bacterial genome and panfungal primers selected from the 5.8S rRNA region for the fungal genome. Results: Dominant genera in mouthwash samples of steroid-naive asthmatics were Neisseria, Haemophilus, and Rothia. The oral microbiota of asthmatic patients on inhaler steroid treatment included Neisseria, Rothia, and Veillonella species. Abundant genera in induced sputum samples of steroid-naive asthma patients were Actinomyces, Granulicatella, Fusobacterium, Peptostreptococcus, and Atopobium. Sputum microbiota of asthma patients taking inhaler steroids were dominated by Prevotella and Porphyromonas. Mucor plumbeus and Malassezia restricta species were abundant in the airways of steroid-naive asthma patients. Choanephora infundibulifera and Malassezia restricta became dominant in asthma patients taking inhaled steroids. Conclusion: The oral and airway microbiota consist of different bacterial and fungal communities in healthy and asthmatic patients. Inhaler steroid use may influence the composition of the oral and airway microbiota.

    Picturing asthma in Turkey: results from the Turkish adult asthma registry
    (Taylor & Francis Ltd, 2023) Celik, Gulfem Elif; Aydin, Omur; Gokmen, Derya; Buhari, Gozde Koycu; Sozener, Zeynep Celebi; Gemicioglu, Bilun; Bulut, Ismet
    IntroductionNational 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.MethodsCase 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.ResultsThe 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.ConclusionThe 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.
