Short Term Mortality

OBJECTIVES: To determine the association between outpatient use of oral antibiotics and 30-day all-cause mortality following hospitalization in a group of elderly chronic obstructive pulmonary disease (COPD) patients.DESIGN:A population-based retrospective cohort study.SETTING:Ontario, Canada.POPULATION STUDIED:All 26,301 patients, 65 years of age or older, who were hospitalized for COPD between 1992 and 1996 in Ontario.METHODS:All elderly patients admitted at least once with a most responsible diagnosis of COPD using the Canadian Institute for Health Information database were identified. They were then linked to the Ontario Drug Benefit database to determine the use of antibiotics within 30 days of the index hospitalization and to the Ontario registered persons database to determine the 30-day mortality following their index hospitalization.RESULTS:Outpatient use of antibiotics within 30 days before the index hospitalization was associated with a significant reduction in the 30-day mortality following hospitalization (odds ratio [OR] 0.83, 95% CI 0.75 to 0.92). Use of macrolides had the lowest relative odds for mortality (OR 0.58, 95% CI 0.47 to 0.73), while use of fluoroquinolones had the highest relative odds (OR 0.98, 95% CI 0.84 to 1.15).CONCLUSIONS:Use of antibiotics before hospitalization was associated with a significant reduction in the risk of short term mortality among a group of elderly COPD patients who eventually required hospitalization for their disease. These findings support the early use of antibiotics in COPD patients who experience an acute exacerbation.

Hrv Analysis

Chronic obstructive pulmonary disease (COPD) is a broad spectrum respiratory illness where there are structural and functional changesin the lungs. According to WHO, COPD is a leading global burden and by 2030 it will be the third leading cause of death worldwide. The structural and functional changes in the lungs in COPD patients tend to inuence the cardiac autonomic functions and heart rate variability (HRV). Previousstudiesshow that there is decrease in heart rate variability in COPD patients. In many previousstudies, it isfound that results ofshort term HRV analysis of 5minutes is comparable to standard 24hours HRV analysis and is very patient friendly and reproducible procedure to analyse the cardiac autonomic functions. So determination of parameters of cardiac autonomic functions with the help of short term HRV analysis in COPD patients is helpful in determining the pathophysiology and subsequent management of such patients. A Descriptive and observational study was conducted upon 100 previously diagnosed COPD patients at the Autonomic function research Laboratory, Department of Physiology, R G Kar Medical College and Hospital, Kolkata, West Bengal. The study includes short term (5min) HRV analysis in COPD patients between the age group 18years and 60years after fullling appropriate inclusion and exclusion criteria and the results were analyzed using proper statistical software. After analysis of different data it was found that there is decrease in heart rate variability (in both Time domain and Frequency domain analysis) in case of COPD and also the decrease is more in case of increasing severity grading of COPD. Sympathetic activity increases and vagal or parasympathetic activity upon heart rate decreases with the increase in COPD grading. Further studies with more number of subjects will be helpful in assessing pathophysiology and management of COPD patients with the help of HRV analysis.

COPD has been recognized as a component of the systemic inflammatory syndrome. A commonly used indicator of the severity and progression of the disease in COPD is expiratory volume per second (FEV1). However, it is weakly associated with symptoms and administration difficulties in elderly patients. Therefore, there is a need for other markers that are better and easy to apply to sick and elderly patients. Plasma fibrinogen can be used as a marker of disease severity. Aim: To estimate the plasma fibrinogen level in patients with COPD and Relationship of levels of plasma fibrinogen with the severity of chronic obstructive pulmonary disease using the BODE classification and GOLD staging. Place and Duration: In the Medicine Unit-II of Jinnah Hospital Lahore for one-year duration from August 2020 to August 2021. Methods: In this cross-sectional study, 110 COPD patients were assessed by measuring plasma fibrinogen correlated with disease severity using the GOLD scale, BODE index and the 6-minute walk test. Results: Plasma fibrinogen is present in all COPD patients. A significant correlation was observed between the BODE index (r = 0.69, p <0.001), gold grading (r = 0.95, p <0.001) and plasma fibrinogen levels. Most of the 110 subjects (34.5%) were Grade II, then Grade III 30.9%, 18.1% Grade IV and 14.5% Grade I. In our study, it was found that the average level of fibrinogen increased with the increase in the GOLD stage, which was statistically significant, and the p value was 0.01. Conclusions: Plasma fibrinogen levels are significantly higher in COPD and can be used as a marker correlating with disease severity in COPD.

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: 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.

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.
