Seasonal Trends in Pneumococcal Carriage in COPD Patients

Chronic Obstructive Pulmonary Disease (COPD)

Patients suffering from chronic obstructive pulmonary disease (COPD) commonly get exacerbations of their illness which have many potential triggers including infection. The most common cause of lung infection/pneumonia is an organism named Streptococcus pneumoniae. In Ireland a 13-valent pneumococcal conjugated vaccine (PCV-13) was recently introduced into the childhood vaccination programme. This study aims to investigate the carriage rate of S. pneumoniae in COPD patients over one year and to determine if isolates of S. pneumoniae found within the COPD population would be covered by the PCV-13 vaccine.

Pulmonary Substudy: A Substudy of Strategic Timing of AntiRetroviral Treatment (START)

Chronic Obstructive Pulmonary DiseaseHIV

The purpose of this study is to find out if starting anti-retroviral therapy (ART) above 500 cluster-of-differentiation-4 (CD4)+ cells/milliliter (mL) ('early ART group') slows the rate of decrease in lung function over time compared to waiting to start ART until the CD4+ drops below 350 cells/mL ('deferred ART group'). Lung function normally declines with age, and both human immunodeficiency virus (HIV) infection and ART have been shown to case a decline in lung function as well. Decline in lung function can be an early indicator of chronic obstructive pulmonary disease (COPD), a significant cause of sickness and death in people with HIV. In this study, lung function will be measured at baseline and every year thereafter by using a spirometer.

Blood Eosinophil Measurements in Patients With Chronic Obstructive Pulmonary Disease

Chronic Obstructive Pulmonary Disease

This study will assess the within-day variation of blood eosinophils in patients with Chronic Obstructive Pulmonary disease (COPD) in stable state and determine if there is a correlation between the blood eosinophils and certain clinical parameters.

Lung Tissue Research Consortium

Chronic Obstructive Pulmonary DiseaseInterstitial Lung Disease

The LTRC will facilitate histopathological research of pulmonary diseases by collecting lung tissues from donors and preparing and distributing collections of tissue specimens to researchers within and outside the LTRC. Collections of specimens will be linked to individual clinical data appropriate to the particular disease. The primary goal of the LTRC is to identify participants with suspected lung cancer or metastatic disease who are willing to provide informed consent for research use of their specimens and data. Secondarily, the LTRC investigators intend to collect clinical data, limited exposure data, physiologic studies, and radiographic studies from these participants.

Patient Factors Associated With Prescription of Antibiotics for Inappropriate Indication in Patients...

Chronic Obstructive Pulmonary DiseaseAcute Exacerbation of COPD

Up to 90% of consulting Acute Exacerbation (AE) of COPD patients are prescribed an antibiotic(1). Rates of inappropriate antibiotic prescription percentage can be as high as 65%(2). Excessive use of antibiotics is correlated with higher prevalence of antimicrobial resistance(3). There are insufficient data regarding the overprescribing antibiotics in AECOPD in our country.Therefore the investigators aimed to investigate the patients factors that are associated with the prescription of antibiotic for inappropriate indication in AECOPD.This is an observational cross sectional study.Population: AECOPD patients with AB(antibiotic) prescription Exposure: Presence of patient factors, Comparison: Absence of Patient factors, Outcome: Prescription of antibiotic for inappropriate indication. Sampling: Consecutive patients presenting to pharmacy between Monday and Friday. Date between January 1 2017 to January 1 30 2019. Primary Outcome:Prescription of antibiotic for inappropriate indication according to Anthonisen criteria for AECOPD Anthonisen criteria:-Worsening of dyspnea Increased sputum volume Increased sputum purulent 3/3 →Type 1 or severe AE 2/3 →Type 2 or moderate AE 1/3 →Type 3 or mild AE AB indicated/useful in Type 1 or severe AE, and Type 2 or moderate AE if sputum is purulent The data will be obtained from the database. Exposure: Patient factors that lead to inappropriate antibiotic prescription (will be considered together in analysis due to confounding) FEV1% Age Current smoker Comorbidities (Charlson comorbidity index) having Frequent exacerbations (≥2 past year) Use of oral steroids Polypharmacy Quality control:Detailed MOP will be developed, A manual for protocol will be written and used to inform the pharmacist,Pharmacist will be trained; to speak to participants in a neutral manner for written informed consent for the security ID(identity) data of the patients,This study will not affect the time period of the participants to access his/her drug. The pharmacy will use the questionnaire within the time period planned. A checklist for exclusion criteria will be developed. A plan for missing data will be developed. Null hypothesis: Patient factors are not associated with the prescription of antibiotics for inappropriate indications in patients with AECOPD Alternative hypothesis: Patient factors are associated with the prescription of antibiotics for inappropriate indications in patients with AECOPD Analysis The data will be analysed using SPSS version 22.0 The investigators will compare exposure variables between inappropriate and appropriate prescription groups Continuous variables - t test or Mann Whitney Binary- chi square test The investigators will use logistic regression to measure the associations between patient factors and the outcome of prescription of antibiotics for inappropriate indication Sample size and power Sample size to estimate CI of 15% around 25 to 50% prevalence of inappropriate prescription with p=0.05 and Power 80% Expected proportion0,25 128 0,50 171 Sample size and power For logistic regression - estimate 30% prevalence (n=143), or about 42 events . The investigators also need 5-10 events for each variable in the model, so this provides sufficient power for 4 to 8 factors. Limitations This study will just determine an association not causality The investigators won't be able to determine if the participant is truthful to the pharmacist The history of participants will be assessed from hospitals e-database - potential for missing data. The Anthonisen criteria for identifying inappropriate AB for AECOPD are still debatable The investigators can not modify many of the patient factors, but may be able to identify patients at higher risk of inappropriate antibiotics Ethics The project will be submitted to the ethical committee of Dr. Suat Seren Chest Disease Hospital Oral and written informed consent will be obtained from all subjects The study will be conducted in accordance with "Good Clinical Practice Guideline" Relevance This study will be the first one to evaluate an association between patient factors and prescription of antibiotic for inappropriate indication in an outpatient clinic of patients with AECOPD in Turkey. Subsequent studies should evaluate physician factors prescription of antibiotic for inappropriate indication.

Analysis of Inhaled Corticoid Prescriptions in General Medicine

AsthmaChronic Obstructive Pulmonary Disease

Chronic obstructive pulmonary disease (COPD) and asthma are frequent and disabling pathologies. The general practitioner is often at the front line vis-a-vis screening, diagnosis and treatment of these pathologies. There are currently many treatments available, in particular inhaled corticosteroids, and although the recommendations for management appear to be well codified in theory, the adaptation of drug therapy remains complex in general practice. The prescription of inhaled corticosteroids, often initiated during a general medicine consultation, is not simple. The aim of this study is to analyze the relevance of the prescription of inhaled corticosteroids in primary care and to identify the criteria necessary for the prescription of inhaled corticosteroids available in general practice. The main objective of our study is to evaluate the rate of consultations where all the elements required for guiding the prescription of an inhaled corticoid are available. The secondary objectives are: Identify other factors associated with decision-making Identify the causes of inhaled corticosteroid stopping (de-prescription)
