    Bronchial hyperresponsiveness in patients with obstructive sleep apnea syndrome
    (Ankara University, 2013) Bulcun E.; Ekici M.; Ekici A.; Tireli G.; Karakoç T.; Şentürk E.; Altinkaya V.
    Introduction: The relationship between obstructive sleep apnea syndrome (OSAS) and bronchial hyperresponsiveness (BHR) is not well known. In this study, we investigated the association between BHR and disease severity in patients with OSAS. Materials and Methods: Fourty seven (37 male/10 female) OSAS patients admitted with polysomnography enrolled to the study. Histamine bronchial challenge test was performed and body mass index (BMI, kg/m2) was calculated. Presence of BHR was diagnosed as positivity of bronchial provocative test (BPT) (PD values ? 16 mg/mL). Patients were questioned with Epworth sleepiness scale (ESS). Results: Histamine bronchial challenge test was positive in 21 of 47 patients. There were significant negative correlations between PD 20 value and AHI (r= -0.47, p= 0.03), BMI (r= -0.45, p= 0.03), and ESS score (r= -0.45, p= 0.03) in the patients with BHR. In addition, AHI (p= 0.03), BMI (p= 0.02), ESS scores (p= 0.03) were higher in patients with BHR (21 patients) than in patients not having BHR (26 patients). Significant negative relation was found between PD 20 value and AHI (?=-0.45, p= 0.03) and significant positive relation was found between presence of BHR and AHI (p= 0.04), BMI (p= 0.03) independently of age and sex in multiple regression analysis. Conclusion: BHR is common in patients with OSAS. As severity of OSAS increased, severity of BHR increased. In addition, obesity may trigger presence of BHR in patients with OSAS.

    Effect of psychological status on respiratory symptoms
    (2005) Ekici A.; Oğuztürk Ö.; Ekici M.; Kurtipek E.; Akin A.; Arslan M.; Tunçkol M.
    Objective: To investigate whether psychological status affects respiratory symptom reporting and objective measures of the respiratory system. Materials and Methods: This study was performed in 1090 male gun factory workers and in 420 women exposed to biomass. The subjects were questioned using a Respiratory questionnaire. Respiratory functions were measured by portable spirometer. Psychological status was measured by HAD scale. Groups with high HAD total scores and low HAD total scores were classified by the median value. Results: In males: Chronic cough (17.6% vs. 10.7% p=0.001), chronic phlegm (13.2% vs. 8.9%, p=0.02), and probable asthma (39.5% vs. 25.5%, p=0.0001) were significantly more frequent in the group with high HAD total scores than in the group with low HAD total scores but definite asthma was not (6.2% vs. 4.6%, p=0.2). In women: Chronic cough (34.8% vs. 23.5% p=0.009), chronic phlegm (23.9% vs. 15.4%, p=0.02), and probable asthma (53.5% vs. 35.3%, p=0.0001) were significantly more frequent in the group with high HAD total scores than in the group with low HAD total scores but definite asthma was not (7.0% vs. 9.0%, p=0.4). Conclusion: Psychological status might affect the frequency of symptom reporting in respiratory questionnaires. The questionnaires and psychological status indices should be interpreted simultaneously.
