Exacerbation Of Copd

Background: Chronic Obstructive Pulmonary Disease (COPD) is characterized by respiratory and extrarespiratory components referring both to systemic complications of COPD, like skeletal muscle myopathy, weight loss and others, and frequently associated comorbidities, interesting various organs and systems (cardiovascular diseases, malignancies, osteoporosis, diabetes, etc.). These comorbidities may increase the rate of hospitalization of COPD patients and have a huge effect on the outcomes of the respiratory disease. Inhalation therapy of COPD with bronchodilators and steroid is primary driven by airflow obstruction, symptoms like dyspnoea, and acute exacerbations. INDACO project has been developed in 2013 to assess the prevalence and type of comorbidities in COPD patients referred to the outpatient wards of some hospitals in Central and South Italy and a preliminary report has recently been published. In the present study, after widening that database, we evaluate the prevalence of comorbidities and the relationships between comorbidities and sex, age, symptoms, lung function and inhalation therapy in COPD patients. Methods: In each enrolled patient, anthropometric and anamnestic data, smoking habits, respiratory function, GOLD (Global initiative for Chronic Obstructive Lung Disease) severity stage, Body Mass Index (BMI), number of acute COPD exacerbations in previous years, presence and type of comorbidities, and the Charlson Comorbidity Index (CCI) were recorded. Results: We collected data of 569 patients (395 males and 174 females, mean age 73 ± 8.5 yrs). The prevalence of patients with comorbidities was 81.2%. Overall number of comorbidities was not related to airflow obstruction and age, but to acute exacerbation of COPD, dyspnoea measured with MRC scale, and male gender. A subgroup analysis revealed that ischaemic heart disease was predominant in males, whereas mood disorders in females. The use of a more complex (multi-drug) inhalation therapy was related with bronchial obstruction measured by FEV1/FVC (p for trend = 0.003) and number of comorbidities (p for trend = 0.001). In multivariate analysis, only airflow obstruction and number of comorbidities were determinant of complexity of therapy, but not MRC and acute exacerbation of COPD. However, the statistical model reached an extreme low degree of significance (r^2 = 0.07). Conclusions: Our study showed a high prevalence of comorbidities in COPD, with some differences related to gender. Number of comorbidities and airflow obstruction represent the determinant of inhalation therapy prescription. Dyspnoea and acute exacerbation of COPD, unlikely suggested by guidelines, are not significant drivers of therapy in the real life setting of our study.

BACKGROUND Pulmonary hypertension (PH) and heart failure are common comorbidities in 20 – 30 % of chronic obstructive pulmonary disease (COPD) patients with acute exacerbation. Similarities in signs and symptoms and lack of objective measures to stratify them at emergency department makes the management difficult. Echocardiography though useful requires specialised training. Hence, B-Type Natriuretic Peptide (BNP) is a simple test that can prognosticate the severity and can influence management in such patients. The purpose of the study was to estimate the significance of BNP during acute exacerbation of chronic obstructive pulmonary disease (AECOPD) as an important marker of severity and to study its correlation with duration of hospital stay, place and mode of management in patients with severe and life-threatening exacerbation of COPD. METHODS This is a prospective longitudinal observational study conducted on 50 patients of severe and life-threatening COPD exacerbation admitted to General Medicine department of HSK hospital, Bagalkot and their outcomes were noted based on the BNP levels. RESULTS The study showed higher levels of BNP in patients admitted to ICU as compared to emergency ward (P = 0.001). Greater values among those on invasive mechanical ventilation vs. non-invasive ventilation (NIV). There was a positive correlation and statistical significance of BNP values with arterial blood gases (ABG) parameters like pulmonary hypertension (PH), partial pressure of carbondi-oxide (PaCO2), partial pressure of oxygen (PaO2), echo parameters like right ventricle (RV) diameter and pulmonary artery systolic pressure (PASP) and duration of hospital stay. CONCLUSIONS BNP is a simple, low cost and easily available blood test that can prognosticate oxygen requirement, mode of ventilation, place of management and can grade and reflect the severity in acute exacerbation of COPD.

Introduction. Arterial blood gas (ABG) analyses have an important role in the assessment and monitoring of the metabolic and oxygen status of patients with acute exacerbation of chronic obstructive pulmonary disease (COPD). Arterial puncture could have a lot of adverse effects, while sampling of venous blood is simpler and is not so invasive. Objective. The aim of this study was to evaluate whether venous blood gas (VBG) values of pH, partial pressure of carbon dioxide (PCO2), partial oxygen pressure (PO2), bicarbonate (HCO3), and venous and arterial blood oxygen saturation (SO2) can reliably predict ABG levels in patients with acute exacerbation of COPD. Methods. Forty-seven patients with a prior diagnosis of COPD were included in this prospective study. The patients with acute exacerbation of this disease were examined at the General Hospital EMS Department in Prijepolje. ABG samples were taken immediately after venous sampling, and both were analyzed. Results. The Pearson correlation coefficients between arterial and venous parameters were 0.828, 0.877, 0.599, 0.896 and 0.312 for pH, PCO2, PO2, HCO3 and SO2, respectively. The statistically significant correlation between arterial and venous pH, PCO2 and HCO3, values was found in patients with acute exacerbation of COPD (p<0.001). Conclusion. When we cannot provide arterial blood for analysis, venous values of the pH, Pv,CO2 and HCO3 parameters can be an alternative to their arterial equivalents in the interpretation of the metabolic status in patients with acute exacerbation of COPD, while the values of venous Pv,O2 and Sv,O2 cannot be used as predictors in the assessment of oxygen status of such patients.

Exacerbation Of Copd

BACKGROUND: Acute exacerbation of COPD (AECOPD) is one of the most common cause of hospital admission. It causes signicant morbidity, mortality and inexorable decline in ling function. Many exacerbations are believed to be due to upper and/ lower respiratory tract viral infections, but the incidence of these infections in patients with COPD is still undetermined. Objectives of the study are-(a) To nd out the viral etiology in patients having acute exacerbation of COPD. (b) To correlate the severity of COPD patients having exacerbations with viral etiology. METHODS: This cross-sectional study was carried out on 70 AECOPD patients admitted in department of Respiratory Medicine, Institute of Respiratory Diseases, SMS Medical College, Jaipur during July 2019–June 2020. Demographic and clinical parameters were recorded from each patient during admission. Twin nasopharyngeal/oropharyngeal swabs were collected and are tested for Respiratory viruses via RT-PCR. RESULTS: Respiratory viruses were detected in 15 of 70 (21.42%) patients during exacerbations of COPD. The viruses detected were inuenza (10%), rhinovirus (5.71%), adenovirus (4.29%) and RSV (1.42%). Majority of the patients had exacerbations in severe COPD subgroup, had duration of hospital stay of more than or equal to 5 days, had one episode of acute exacerbation per year and 5, 9, 11 respiratory viruses were detected in this group respectively. CONCLUSION: Viral infections seem to contribute to the exacerbations of COPD in our settings and should be strongly considered in the management of such patients. Considering appropriate antiviral therapy can timely reduce morbidity in an event of an inuenza viral exacerbation.

ObjectivesMicroalbuminuria (MAB) is a sensitive biomarker of cardiovascular risk that is directly associated with cardiovascular events and mortality. Recent studies have evaluated the presence of MAB in patients with stable chronic obstructive pulmonary disease (COPD) or hospitalised for acute exacerbation of COPD (AECOPD).MethodsWe evaluated 320 patients admitted for AECOPD in respiratory medicine departments of two tertiary hospitals. On admission, demographic, clinical and laboratory values and COPD severity were assessed. Patients were evaluated monthly for 1 year, recording new AECOPD and death from any cause.ResultsPatients with documented MAB (urinary albumin excretion of 30–300 mg/24 hours) on admission had worse lung function (forced expiratory volume in 1 s, %) (mean (SD) 34.2 (13.6)% vs 61.5 (16.7)%), higher modified Medical Research Council (3.6 (1.2) vs 2.1 (0.8)), lower 6 min walk test (171 (63) vs 366 (104)) and more hospitalisation days (9 (2.8) vs 4.7 (1.9)) (p<0.001 for all comparisons). MAB was also correlated with Global Initiative for Chronic Obstructive Lung Disease 2020 COPD stages (p<0.001). In multivariate regression analysis, MAB was a significant predictor of longer hospitalisation duration (OR 6.847, 95% CI 3.050 to 15.370, p<0.0001). Twelve-month follow-up revealed that patients with MAB experienced more AECOPDs (4.6 (3.6) vs 2.2 (3.5), p<0.0001) and deaths, n (%) (52 (36.6) vs 14 (7.8), p<0.001). Kaplan-Meier survival curves demonstrated that patients with MAB presented with increased mortality, AECOPD and hospitalisation for AECOPD risk at 1 year (p<0.001 for all comparisons).ConclusionsThe presence of MAB on admission for AECOPD was associated with more severe COPD and prolonged hospitalisation, as well as with higher rates of AECOPD and mortality risk at 1-year follow-up.

Background: Chronic obstructive pulmonary disease (COPD) is a major cause of chronic morbidity and mortality worldwide. Acute exacerbation is an acute and sustained worsening of a patient’s condition from a stable state and it is associated with significant electrolyte disturbances. Objectives: The main objective of this study was to determine the prevalence of electrolyte disturbances in patients with acute exacerbation of COPD and to determine possible effects of these electrolyte disorders. Materials and Methods: This observational prospective study was carried out in the Department of Pulmonology, Enam Medical College & Hospital from 1st January to 31st December 2017. Sixty patients with acute exacerbation of COPD were included. Serum electrolytes and arterial blood gases were measured. Results: Low level of serum sodium (131 ± 5.66 mEq/L) and potassium (3.20 ± 0.44 mEq/L) were found in subjects with acute exacerbation of COPD. In patients with respiratory failure Na+ and K+ levels were even lower. Conclusion: Serum electrolytes in acute exacerbation of COPD patients should be monitored routinely and should be corrected early to avoid poor outcomes. J Enam Med Col 2019; 9(1): 25-29

Introduction: Chronic Obstructive Pulmonary Disease (COPD) is one of the leading causes of mortality and morbidity worldwide. Though COPD is mainly a chronic disease, many patients experience exacerbations that are related to worst survival outcome, especially with abnormal serum electrolyte level. The objective of this study was to evaluate serum electrolyte levels among the patients with acute exacerbation of COPD. Methods: Structured questionnaire and patients’ charts were used to collect data. Data was analyzed using Statistical Package for the Social Sciences (SPSS) software version 16.0 and descriptive statistics were used to generate the research findings. Results: The mean age of the patients with Acute exacerbation of COPD was 69.57± 9.765 years. Among 100 patients, (83%) belonged to the age group of 60 years and above, (54%) were male, (74%) were married, (52%) were illiterate and (41%) were engaged in agriculture, (41%) consumed alcohol and (67%) were smokers. Dyspnoea (90%) was the most common symptom. The mean level of sodium and potassium were 133.8±4.830 mEq/L, 3.6±0.533 mmol/L, respectively. Fifty seven percent patients had electrolyte disorder. More than half (51%) had hyponatremia and (40%) had hypokalemia. The average value of pH, PaCO2 and PaO2 are 7.34 ± 0.727, 46.64 ± 9.787 mm Hg and 69.38 ± 9.255 mm Hg respectively. Among them, (18%) were in respiratory failure. Conclusion: This study concluded that hyponatremia and hypokalemia are prevalent electrolyte disorder with AE of COPD patients. Therefore, we recommend routine monitoring of the serum electrolytes for better outcomes of patients.
