The Efficacy and Prevalence of Montelukast Therapy in Cough-Variant Asthma Patients in Al-Kindy Teaching Hospital

BACKGROUND: Cough-variant asthma (CVA) is a type of asthma in which the main symptom is a dry, non-productive cough.
 OBJECTIVE: The objective of the study was to evaluate the therapeutic effect of Montelukast in CVA and to investigate the prevalence of Montelukast in CVA.
 METHODS: A cross-sectional study was conducted on 30 patients with chronic cough at least 8 weeks using Montelukast at Al-Kindy Hospital over the period of January 2018‒March 2018. An interview using questionnaire was used to collect the data that were specifically prepared to meet the objective of study including age, sex, associated disease, exacerbation factors, and classical therapy.
 RESULTS: There was a reduction of the symptoms associated with CVA after treatment with Montelukast. The prevalence of exacerbation factors was as follows: Dust (73.3%) of patients, food (36.7%), exercise (60%), psychological (56.7%), smoking (30%), and others (perfume and cold weather) (26.7%). The usage of Montelukast in this study was 73.3% (22 patients). Patients using Montelukast have shown improvement of symptoms as follows: Chest pain was relieved from 57.1% of patients, exhaustion (58.3%), vomiting (76.5%), sleep disturbance (54.5%), affecting daily life in 57.1%, and syncope 66.7%.
 CONCLUSION: The prevalence of Montelukast administration to the patients with chronic cough in our study was found to be more than 70% of the 30 total patients. Montelukast usage leads to reduction in the frequency of chronic cough and the symptoms associated with it.

High frequency of chronic cough and sputum production with lowered exercise capacity in young smokers

Objectives. The aim was to evaluate how cigarette smoking is associated with respiratory symptoms, fitness, and anthropometric measures in young smokers. Methods. The prevalence of smoking was investigated in a cohort of young military draftees (n = 1130; 98% between 18–21 years of age) in Northern Finland. The associations of smoking with respiratory symptoms, physical fitness (12-min running test), education, and anthropometric measures were analysed using a self-reported questionnaire with high response rate (80%). Results. Almost half (46.5%) of the young males were daily smokers, 17.4% being occasional smokers. The prevalence of self-reported chronic cough and sputum production was high in daily smokers (40.7%) and occasional smokers (26.9%) compared to non-smokers (12%). These symptoms were significantly associated with the smoking history. Aerobic fitness was worse in regular smokers compared to non-smokers (P < 0.001). Smokers had a higher body mass index than non-smokers (P = 0.035). In the regular smokers, the more active the subjects were in sports, the less they smoked when evaluated by pack year history (P < 0.001). Smokers had a lower educational level than occasional smokers or, especially, non-smokers (P < 0.001). Conclusions. The frequency of young smokers with chronic cough and sputum production was very high, posing a serious risk to their future health.

Urban and social origins of childhood bronchitis in England and Wales.

A survey of respiratory disease in over 10,000 children aged 6 to 10 years living in contrasting urban and rural areas of England and Wales showed pronounced social class gradient in the frequency of chronic cough, history of bronchitis, and also in disease of ears and nose. A consistent rise in the frequency of chest conditions with increasing local levels of air pollution was clearly seen only among the children of semi-skilled and unskilled workers. No such gradient was obvious for diseases of the ear and nose. These trends in chest disease in children paralleled similar trends in mortal and disabling bronchitis among adults in the same areas. The excess rate for bronchitis in children and adults found in South Wales could not be accounted for by local levels of air pollution.
