Expired air nitric oxide was measured in 113 subjects (26 healthy controls, 64 bronchial asthma (BA) patients and 23 COPD patients. In BA patients 10 had mild course of the disease. In 50 the course was estimated as moderate, 4 patients had severe course of the disease. In 20 patients BA was associated with COPD. The results revealed the dependence of FeNO on following factors: severity of the disease: in severe and moderate BA course FeNO was significantly higher than in mild BA; on phase of the disease: in exacerbation FeNO was significantly higher than in remission; on control of the disease: in patients, in whom it was difficult to reach the disease control, FeNO was higher than in others. In COPD patients FeNO was significantly lower than in BA ones. Even in subjects with marked airways inflammation manifested by high sputum cellularity FeNO was low.

BACKGROUND: a comparative analysis of laboratory and instrumental tests at patients with bronchial obstructive diseases seems very actual due to the wide prevalence of these diseases. THE AIM: to evaluate characteristics of spirometry as well as allergic (total IgE, sputum eosinophils) and infectious (blood and sputum leucocytes, ESR, CRP, fibrinogen) inflammation markers at patients with bronchial obstructive diseases. PATIENTS AND METHODS: 104 case histories of patients with bronchial asthma, chronic obstructive pulmonary disease and overlap were analyzed including age, duration of smoking (pack-years), laboratory (clinical blood test, biochemical blood test, general sputum analysis, sputum culture) and instrumental (spirometry, body plethysmography, echocardiography) tests. Data were processed statistically with non-parametric methods. RESULTS: COPD patients were older than other groups’ patients, had the highest pack-years index. ACO patients were marked with maximal TLC and Raw, minimal FEV1, FEF25-75, FEV1/FVC. Patients with COPD had the highest inflammation markers (leucocyte count, CRP, fibrinogen). CONCLUSION: high active inflammation may cause severe lower airways possibility disorders at patients with COPD. Data related to a possible role of K. pneumoniaе in the pathogenesis of eosinophilic inflammation in lower airways are of significant interest. Patients with ACO occupy an intermediate position between asthma and COPD patients based on clinical and functional features.

AbstractBronchial asthma and chronic obstructive pulmonary disease (COPD) are the major obstructive disorders that may contribute to the severity in individual patients. The present study was designed to compare the efficacy and safety of theophylline and doxofylline in patients with bronchial asthma and COPD.A total of 60 patients, 30 each with bronchial asthma and COPD, were enrolled for the study. Each group of 30 patients received standard treatment for asthma and COPD. Each group was again subdivided into two with 15 patients each, who received theophylline or doxofylline in addition to standard therapy, for a period of 2 months. Each patient was followed up fortnightly for the assessment of efficacy parameters using a pulmonary function test (PFT), clinical symptoms and emergency drug use, and safety was assessed by recording adverse drug reactions.Both theophylline and doxofylline produced enhancements in PFT at different time intervals in both asthma and COPD patients. The maximum beneficial effects were seen at 6 weeks for asthma patients and at 8 weeks for COPD patients for both theophylline and doxofylline.The comparative study showed that doxofylline was more effective as evidenced by improvement in PFT as well as clinical symptoms, and reduced incidence of adverse effects and emergency bronchodilator use.

Background: Psychiatric co morbidities tend to occur quite frequently in patients of chronic respiratory diseases mainly bronchial asthma and Chronic Obstructive Pulmonary Disease (COPD) but still it is highly under diagnosed. Aim and objective of the study was to find out the prevalence of psychiatric co morbidities in asthma and COPD and to correlate them with disease severity according to Global Initiative against Obstructive Lung Disease (GOLD) and Global Initiative against Asthma (GINA) guidelines.Methods: Study was conducted in Department of TB and Chest in association with Department of Psychiatry of Punjab Institute of Medical Sciences, a secondary care medical college in north India. A total 204 patients, 68 of bronchial asthma, 68 0f COPD and 68 were controls included in the study. Diagnosis and severity of respiratory diseases was assessed by spirometry. Evaluation of psychiatric co morbidities was done using the MINI international neuropsychiatric interview questionnaire.Results: The frequency of psychiatric co morbidities in COPD patients was significantly higher (32.4%) compared to patients of bronchial asthma (20.6%). The most common co morbidity in both arms was generalized anxiety disorder (17.6% in COPD patients and 10.3% in patients of bronchial asthma.Conclusions: COPD patients have a higher frequency of psychiatric co morbidities compared to bronchial asthma patients and control population. These should be properly screened and treated.

Introduction The oral cavity and pharynx have a rich sensory system composed of specialized receptors. The integrity of oropharyngeal sensation is thought to be fundamental for safe and efficient swallowing. Chronic obstructive pulmonary disease (COPD) patients are at risk for oropharyngeal sensory impairment due to frequent use of inhaled medications and comorbidities including gastroesophageal reflux disease. Objective This study aimed to describe and compare oral and oropharyngeal sensory function measured using noninstrumental clinical methods in adults with COPD and healthy controls. Method Participants included 27 adults (18 men, nine women) with a diagnosis of COPD and a mean age of 66.56 years ( SD = 8.68). The control group comprised 11 healthy adults (five men, six women) with a mean age of 60.09 years ( SD = 11.57). Spirometry measures confirmed reduced functional expiratory volumes (% predicted) in the COPD patients compared to the control participants. All participants completed a case history interview and underwent clinical evaluation of oral and oropharyngeal sensation by a speech-language pathologist. The sensory evaluation explored the detection of tactile and temperature stimuli delivered by cotton swab to six locations in the oral cavity and two in the oropharynx as well as identification of the taste of stimuli administered in 5-ml boluses to the mouth. Analyses explored the frequencies of accurate responses regarding stimulus location, temperature and taste between groups, and between age groups (“≤ 65 years” and “> 65 years”) within the COPD cohort. Results We found significantly higher frequencies of reported use of inhaled medications ( p < .001) and xerostomia ( p = .003) in the COPD cohort. Oral cavity thermal sensation ( p = .009) was reduced in the COPD participants, and a significant age-related decline in gustatory sensation was found in the COPD group ( p = .018). Conclusion This study found that most of the measures of oral and oropharyngeal sensation remained intact in the COPD group. Oral thermal sensation was impaired in individuals with COPD, and reduced gustatory sensation was observed in the older COPD participants. Possible links between these results and the use of inhaled medication by individuals with COPD are discussed.

Background: Chronic obstructive pulmonary disease (COPD) is preventable and treatable disease state characterized by air flow limitation that is not fully reversible. Severity of the symptoms is increased during exacerbations. Objectives: The purpose of the study is to assess and improve the knowledge regarding COPD among study subjects. Materials and Methods: A Cross-sectional interventional study was carried out among the peoples in selected areas of the Chitradurga city for a period of six months. Result: A total 207 subjects enrolled in the study in that 155 male and 52 females. In our study mean score of post test was more (5.87±1.68) when compare to pre-test (2.63±1.46) which show significant increase in their knowledge after educating them (p=0.000). A total of 207 subjects were enrolled into the study. SPSS Software was used to calculate the statistical estimation. Paired t-test was used to detect the association status of different variables. Conclusion: The relatively good level of COPD awareness needs to be maintained to facilitate future prevention and control of the disease. This study had identified that negative illness perceptions should be targeted, so that they will not avoid patients from seeking for COPD treatment and adhere to it. Key words: Cross sectional study, Knowledge, practice, COPD.

Abstract Objective Chronic obstructive pulmonary disease (COPD) is a complicated multi-factor, multi-gene disease. Here, we aimed to assess the association of genetic polymorphisms in LINC01414/ LINC00824 and interactions with COPD susceptibility. Methods Three single nucleotide polymorphisms (SNPs) in LINC01414/LINC00824 was genotyped by Agena MassARRAY platform among 315 COPD patients and 314 controls. Logistic analysis adjusted by age and gender were applied to estimate the genetic contribution of selected SNPs to COPD susceptibility. Results LINC01414 rs699467 (OR = 0.73, 95% CI 0.56–0.94, p = 0.015) and LINC00824 rs7815944 (OR = 0.56, 95% CI 0.31–0.99, p = 0.046) might be protective factors for COPD occurrence, while LINC01414 rs298207 (OR = 2.88, 95% CI 1.31–6.31, p = 0.008) risk-allele was related to the increased risk of COPD in the whole population. Rs7815944 was associated with the reduced risk of COPD in the subjects aged > 70 years (OR = 0.29, p = 0.005). Rs6994670 (OR = 0.57, p = 0.007) contribute to a reduced COPD risk, while rs298207 (OR = 7.94, p = 0.009) was related to a higher susceptibility to COPD at age ≤ 70 years. Rs298207 (OR = 2.54, p = 0.043) and rs7815944 (OR = 0.43, p = 0.028) variants was associated COPD risk among males. Rs7815944 (OR = 0.16, p = 0.031) was related to the reduced susceptibility of COPD in former smokers. Moreover, the association between rs298207 genotype and COPD patients with dyspnea was found (OR = 0.50, p = 0.016), and rs7815944 was related to COPD patients with wheezing (OR = 0.22, p = 0.008). Conclusion Our finding provided further insights into LINC01414/LINC00824 polymorphisms at risk of COPD occurrence and accumulated evidence for the genetic susceptibility of COPD.
