Prevalence and risk factors of allergies in Turkey: Results of a multicentric cross-sectional study in children

The Prevalence And Risk Factors of Allergies in Turkey (PARFAIT) study was planned to evaluate prevalence and risk factors of asthma and allergic diseases and also to find out which geographical variables and/or climatic conditions play a role determining the prevalence of allergic diseases in Turkish school children. Study was planned as cross‐sectional questionnaire‐based. About 25,843 questionnaires from 14 centers were appropriate for analysis. Parental history of allergy, having an atopic sibling and other atopic disease in index case was significant risk factors for all allergic diseases. Breast feeding decreased the risk of current asthma (OR: 0.92, CI: 0.86–0.99) and wheezing (OR: 0.93, CI: 0.87–0.99) but not allergic rhinitis and eczema. Respiratory infection in the past was an important risk factor for the occurrence of allergic diseases especially for asthma which was increased 4.53‐fold. Children exposed to household smoke were significantly at higher risk of asthma, wheezing, and allergic rhinitis (OR: 1.20, CI: 1.08–1.33; OR: 1.21, CI: 1.09–1.34; and OR: 1.32, CI: 1.21–1.43, respectively). All allergic diseases were increased in those children living in areas which have altitude of below 1000 m and mean yearly atmospheric pressure above 1000 mb. The study has suggested that household and country‐specific environmental factors are associated with asthma, wheezing, allergic rhinitis, and eczema risk during childhood in Turkey.

Prevalence and Risk Factors of Allergies in Turkey (PARFAIT): results of a multicentre cross-sectional study in adults

The Prevalence and Risk Factors of Allergies in Turkey (PARFAIT) study was planned to evaluate the prevalence of and risk factors for asthma and allergic diseases in Turkey. The present analysis used data from 25,843 parents of primary school children, obtained from a cross-sectional questionnaire-based study. A total of 25,843 questionnaires from 14 centres were evaluated. In rural areas, the prevalences asthma, wheezing, allergic rhinitis and eczema in males were: 8.5% (95% confidence interval (CI) 7.9–9.1%), 13.5% (95% CI 12.8–14.2%), 17.5% (95% CI 16.7–18.2%) and 10.8% (95% CI 10.2–11.4%), respectively; and in females were: 11.2% (95% CI 10.9–11.8%), 14.7% (95% CI 14.3–15.1%), 21.2% (95% CI 20.4–22.0%) and 13.1% (95% CI 12.4–13.8%), respectively. In urban areas, the corresponding prevalences in males were: 6.2% (95% CI 5.8–6.6%), 10.8% (95% CI 10.3–11.3%), 11.7% (95% CI 11.4–12.0%) and 6.6% (95% CI 6.2–7.0%), respectively; and in females were: 7.5 % (95% CI 7.9–7.1%), 12.0% (95% CI 11.7–12.3%), 17.0% (95% CI 16.4–17.6%) and 7.3% (95% CI 6.9–7.7%), respectively. Having an atopic first-degree relative or any other atopic diseases had significant effects on the prevalence of allergic diseases. Housing conditions, such as living in a shanty-type house, visible moulds at home and use of wood or biomass as heating or cooking material were associated with one or more allergic diseases. Although genetic susceptibility is strongly associated, country- and population-based environmental factors may contribute to increased prevalence rates of allergic diseases.

Turkish physicians’ perception of allergic rhinitis and its impact on asthma

Background:  The clinical association of rhinitis and asthma has been recognized for centuries, leading to a current definition of ‘one airway, one disease’. Current findings indicate that the optimal treatment of rhinitis might improve coexisting asthma.

Fractional exhaled nitric oxide (FeNo) in different asthma phenotypes.

Fractioned exhaled nitric oxide (FeNO) is a noninvasive marker of inflammation in asthmatic patients. FeNO can be used to monitor airway inflammation, but individual responses make tailored interventions based on FeNO difficult. The correlation between the asthma control test (ACT), FEV1, and FeNO was evaluated in this study to ascertain the correct usage of FeNO with different asthma phenotypes regarding their control, allergy, comorbidity, obesity, age, smoking status, and severity. ACT, pulmonary function, and FeNO in 416 asthmatic patients on combined therapy were retrospective evaluated. Correlations between these parameters and the FeNO levels in different asthma phenotypes were calculated. In the study population, FeNO was 31.8 ± 28.5 parts per billion (ppb), FEV1 was 83.4 ± 19% and ACT was 19 ± 5.2. ACT scores were negatively correlated with FeNO (r = −0.31; p = 0.002). FeNO was different in patients with positive and negative skin-prick test (p < 0.05), with and without allergic rhinitis (p < 0.01), and with and without allergic conjunctivitis (p < 0.01). Significantly higher FeNO levels were found with logistic regression analysis only in patients with a history of emergency room visits (ERVs) (p = 0.024). The rate of the ERV of the patients with an ACT score more than or equal to 20 and with a FeNO value of more than 35 ppb was 22.9%, but with a FeNO value of less than 35 ppb was 6.5% (p = 0.004). Allergy and allergic comorbidities may lead to an increase in FeNO levels. Patients with a history of ERV have markedly higher FeNO levels, although they have an ACT score more than or equal to 20.

The Allergic Rhinitis and its Impact on Asthma (ARIA) score of allergic rhinitis using mobile technology correlates with quality of life: The MASK study

Mobile technology has been used to appraise allergic rhinitis control, but more data are needed. To better assess the importance of mobile technologies in rhinitis control, the ARIA (Allergic Rhinitis and its Impact on Asthma) score ranging from 0 to 4 of the Allergy Diary was compared with EQ‐5D (EuroQuol) and WPAI‐AS (Work Productivity and Activity Impairment in allergy) in 1288 users in 18 countries. This study showed that quality‐of‐life data (EQ‐5D visual analogue scale and WPA‐IS Question 9) are similar in users without rhinitis and in those with mild rhinitis (scores 0‐2). Users with a score of 3 or 4 had a significant impairment in quality‐of‐life questionnaires.

Investigation of knowledge of asthma and inhaler devices in pharmacy workers.

Abstract Objective: Effective management of asthma requires the development of a partnership between the patient and his or her health care professionals. In a number of countries, including Turkey, pharmacy workers are the last link in the asthma therapy chain and usually give information to their patients about the use of these drugs and asthma. As a result, we investigated knowledge of asthma and the use of inhaler devices in pharmacy workers in Istanbul pharmacies. Methods: The study was performed with 266 pharmacists and 261 pharmacist assistants selected from 4221 pharmacies in Istanbul by random sampling, with a 90% confidence interval. Each patient was asked to fill out a questionnaire that measured their knowledge of asthma. They were also asked to demonstrate how to use the inhaler devices. Results: The high number of incorrect answers to the 11th question, that ‘‘the majority of upper respiratory tract infections triggering asthma are viral’’, may be a contributor to the unnecessary use of antibiotics in Turkey (incorrect answers from 41.2% of pharmacists and 34.5% of pharmacist assistants). Scores for inhalation device techniques for the pharmacists were as follows: metered-dose inhaler (MDI), 4.9 ± 3.9; discus, 4.4 ± 3.7; aerolizer, 4 ± 3.1; and turbuhaler, 3.8 ± 2.9. Conclusions: Istanbul pharmacy workers have limited knowledge about asthma and inhaler devices and need further education, which may contribute to improved asthma control in Turkey.

Evaluation of laryngeal findings in users of inhaled steroids

The objective of the prospective study is to examine the laryngeal changes by laryngeal videostroboscopy and electromyography (EMG) regarding new-onset dysphonia in asthmatic patients taking inhaled corticosteroids (ICS). Laryngeal changes and electrophysiological status of the laryngeal muscles were evaluated by these methods in 12 patients both at the time of presentation of dysphonia and after cessation of therapy. Laryngeal changes of our patients were mucosal edema, erythema, thickening, adduction deficit, nodule and irregularity in videostroboscopy. Significant correlations were found between laryngeal pathology and dosage and duration of ICS therapy. We detected myopathy by EMG in most of the patients. Also, EMG revealed that cricothyroid muscle was much more affected than thyroarytenoid muscle. In conclusion, we consider that steroid myopathy or mucosal inflammatory theory alone is not sufficient to explain the etiopathogenesis of dysphonia in asthmatic patients taking ICS. The laryngeal mucosal changes were detected by laryngeal videostroboscopic examination in some asthmatic patients, with dysphonia using ICS, and/or laryngeal myopathy was found by laryngeal EMG in some of them in this study. Thus, various factors may have role simultaneously in the occurrence of dysphonia.

Treatment of allergic rhinitis using mobile technology with real world data: The MASK observational pilot study

Large observational implementation studies are needed to triangulate the findings from randomized control trials as they reflect “real‐world” everyday practice. In a pilot study, we attempted to provide additional and complementary insights on the real‐life treatment of allergic rhinitis (AR) using mobile technology.

Asthma control test via text messaging: could it be a tool for evaluating asthma control?

Abstract Introduction: Originally, the Asthma Control Test (ACT) was designed for English-speaking patients using a paper-and-pencil format. The Turkish version of the ACT was recently validated. This article compares the paper-and-pencil and web-based texting formats of the Turkish version of the ACT and evaluates the compatibility of these ACT scores with GINA-based physician assessments of asthma control. Methods: This multicentre prospective study included 431 asthma patients from outpatient clinics in Turkey. The patients were randomized into a paper-and-pencil group (n = 220) and a text messaging group (n = 211). Patients completed the ACT at Visit 1, after 10 ± 2 days, and at 5 ± 1 week to demonstrate the reliability and responsiveness of the test. At each visit, physicians assessed patients’ asthma control levels. Results: The ACT administered via texting showed an internal consistency of 0.82. For the texting group, we found a significant correlation between the ACT and physician assessments at Visit 1 (r = 0.60, p < 0.001). The AUC was 0.87, with a sensitivity of 78.0% and a specificity of 77.5% for a score of ≤19 for screening “uncontrolled” asthma in the texting group. Conclusion: When the Turkish version of the ACT was administered via either the paper-and-pencil or text messaging test, scores were closely associated with physician assessments of asthma control.
