Item Thrombin lag time is increased in children with mild asthma(2019) Koksal, B.T.; Eker, I.; Ozbek, N.Y.; Dogan, I.; Ozbek, O.Y.; 0000-0001-9580-7656; 30262412Background: Inflammation and coagulation are closely linked events. Thrombin is the key enzyme in coagulation system and also has roles in inflammation. Objective: The aim of our study was to evaluate thrombin generation in children with mild asthma. Methods: Forty-two children with mild asthma and 49 healthy children were included in the study. All patients performed spirometry. Thrombin generation tests (TGT) were performed with a calibrated automated thrombogram (CAT) in children without asthma exacerbation during the last six months. During CAT assay thrombogram curves were obtained. The area under the curve showed endogenous thrombin potentials and indicated the total amount of endogenous thrombin generated; the peak height showed the highest thrombin value, thrombin lag time and time to thrombin peak were measured. Results: Thrombin lag time was significantly longer in children with asthma (3.98 1.2 min) compared to those in the control group (3.29 +/- 0.6 min) (p < 0.01). Children with asthma also had longer thrombin tail time compared to the control group (19.5 +/- 8.9 min vs. 16.7 +/- 2.9 min, p= 0.02). Thrombin peak was inversely correlated with FEF 25-75 (r =-0.41, p < 0.01). Thrombin lag time was inversely correlated with FEF 25-75 (r=-0.39, p<0.01). Conclusion: Inflammation in mild asthma seems to disturb coagulation but this disturbance may not be so strong as to increase thrombin levels and may only affect the initiation phase of thrombin generation.

For this reason, it is important to question and improve the knowledge of primary health care physicians. This study is designed to assess the level of knowledge for bronchial asthma and COPD of the primary healthcare physicians, both before and immediately after an educational course structured in the context of GARD Chronic Airway Diseases National Control Program. Materials and Methods: The participating physicians attended an intensive educational course on asthma and COPD. Twenty five item questionnaires for asthma and COPD were administered to the participants both before and immediately after the end of the course. Contribution of education to the level of knowledge was investigated by comparing the percentages of the correct answers in the pre-and post-test. Results: From 11 different cities, 1817 and 1788 primary health care physician were attended to the asthma and COPD educations, respectively. The accuracy rate of >= 75% was obtained from only 4 questions in pre-test asthma questionnaire. On the contrary, in 15 questions the accuracy rate was < 50%. The mean accuracy rate for the whole asthma test was 45.8%, and this rate raised to 69.6% after education course. The accuracy rate of >= 75% could not be obtained from any of the questions in pre-test COPD questionnaire. On the contrary, in 19 questions the accuracy rate was < 50%. The mean accuracy rate for the whole asthma test was 42.0%, and this rate raised to 71.3% after education course. Conclusion: It has been shown that, in primary care settings, the level of knowledge in asthma and COPD should be enhanced and that this increase can be achieved with an education course.Item Angiopoietin-1, Angiopoietin-2, and Periostin Levels in Children with Recurrent Wheeze(2018) Koksal, Burcu Tahire; Aydin, Beril Ozdemir; Tekindal, Agah; Ozbek, Ozlem YilmazBackground: Recurrent wheeze (RW) is frequent in preschool children. Wheezing phenotypes, asthma predictive index (API), and modified API (mAPI) have been described for clinical purposes. Our aim was to examine whether inflammatory markers including serum angiopoietin (Ang)-1, Ang-2, and periostin levels differ according to wheezing phenotypes and mAPI. Materials and Methods: Ninety-eight children who were <4 years of age with history of at least 4 episodes of wheezing during the past 12 months and 51 age-matched healthy controls were included in the study. Children with RW were classified according to wheezing phenotypes as episodic viral wheeze or multitrigger wheeze, and positive or negative mAPI. Blood for Ang-1, Ang-2, and periostin levels was drawn during wheezing episode-free periods. Results: Atopic children with RW (31.4 +/- 34.4 ng/mL) demonstrated higher serum Ang-1 levels than nonatopic children (16.5 +/- 13.8 ng/mL) with RW (P = 0.03). When we compared children according to wheezing phenotypes, we could not find any difference in serum Ang-1, Ang-2, and periostin levels between groups. Children with positive mAPI showed similar Ang-1, Ang-2, and periostin levels with children having negative API and healthy children. Conclusions: We have found higher serum Ang-1 levels in atopic children with RW, and this result might be explained by increased inflammation. The evidence was not strong enough to associate serum Ang-1, Ang-2, or periostin and asthma in preschool children with RW. However, Ang-1 can be a candidate for investigating its role in predicting atopic children and diagnosing atopic childhood asthma.
