Filter by:The goal of this observational study is to evaluate the frequency and predictors of exacerbations in COPD patient population in Uganda. The main questions it aims to answer are:- 1. What is the proportion of frequent exacerbators (≥2/year) and what factors are associated with the frequent exacerbator phenotype? 2. What is the frequency of exacerbations and what factors are correlated with exacerbation frequency? Participants will be asked to offer demographic ,clinical and exposure questions. Questionnaires assessing disease burden, and quality of life will be administered. Clinical measurements, and complete blood count will be collected ta baseline and on sick visits. Spirometry will be measured at baseline and on the last visit. Samples will be collected for storage. Participants will be followed up for one year.
The aim of this study is to quantify the burden of severe AECOPD in South Korea, by investigating the association between frequency of severe AECOPD and clinical and health-care utilization outcomes.
Although we know that these numbers are underestimated, Chronic obstructive pulmonary disease (COPD) is a common chronic respiratory disease that affects between 8 and 12% of adults. According to a 2020 WHO report, it is the third most common cause of mortality in developed countries. This disease is punctuated by exacerbations associated with an 8% mortality of hospitalized patients, increased to 24% when the patient is admitted to intensive care unit. Early detection and treatment of these exacerbations appears to be essential to improve patient survival. End-tidal carbon dioxide (EtCO2) is used to assess a patient's respiratory and hemodynamic status. Indeed, EtCO2 is a non-invasive measure that could allow the estimation of arterial carbon dioxide (PaCO2) without performing blood gases, an arterial blood sampling, classically at the radial artery. This study aimed to find an EtCO2 value which at the time of the initial management, would be predictive of a severe COPD exacerbation, as well as PaCO2.
Lower respiratory tract infections (LRTI) in patients with chronic lung diseases are a common acute reason to consult respiratory practitioners and often lead to inadequate prescription of antibiotics. The primary objective of the investigators study was to determine the diagnostic accuracy of point-of-care testing (POCT) for procalcitonin (PCT) in identifying pneumonia as a bacterial infection in outpatients with LRTI.
The main objective of this RE-SAMPLE cohort study is to identify from a real-world data (RWD) set that will be collected, a subset of data that can be potentially used as important predictors and parameters for disease progression of COPD and complex chronic conditions, and multi-morbid exacerbations. The secondary objective is to evaluate the feasibility of RWD collection from a patient's perspective. Study design: This is a prospective observational cohort study to collect RWD in patients with COPD and complex chronic conditions, with a maximum of 38 months of follow-up. Measurements are performed and RWD are collected by using the Healthentia mobile phone application at baseline (e.g. patient characteristics), daily (e.g. symptom diary), during follow-up visits and at deterioration, and from hospital data (e.g. healthcare visits). The choice of parameters and measurement tools that will be collected during the cohort will be updated every three months during the first year of the cohort (via protocol amendments). These updates are based on citizen-design sessions and on new literature insights. Prognostic models will be developed including predictors derived from the RWD collection.
Inspiratory muscle weakness, limited functional exercise capacity and worse quality of life have been shown in patients with exacerbation of chronic obstructive pulmonary disease (COPD). Recommendations from clinical practice guideline state that promoting pulmonary rehabilitation after exacerbation can improve the conditions above. Inspiratory muscle training (IMT) has been proven to enhance inspiratory muscle strength and endurance in patient with stable COPD. However, there is less research on whether IMT in addition to pulmonary rehabilitation after exacerbation can benefit inspiratory muscle function, functional exercise capacity and quality of life in patients with COPD. The purpose of this study is to examine the effects of IMT in addition to pulmonary rehabilitation on respiratory muscle function, functional exercise capacity and quality of life in patients with exacerbation of chronic obstructive pulmonary disease.
The purpose of this study is to investigate the anti-viral effects of low-dose AZM treatment in patients with asthma and COPD with an exacerbation history. The investigators expect that long-term treatment with low dose AZM modulates the immune response to viral infections, with an increased interferon release, in patients with asthma and COPD with an exacerbation history. In addition, the investigators expect a decrease in inflammatory cells and mediators, and changes in bacteria, measured in samples from the lungs. Half of the participants will receive azithromycin on top of their regular asthma/COPD treatment, while the other half will receive placebo on top of their regular asthma/COPD treatment.

The global objective of this coordinated project is to test the following hypotheses: 1) the lung microbiome in chronic obstructive pulmonary disease (COPD) is different in patients suffering from frequent exacerbations (FE) compared those who do not (NE ); 2) The microbial profile of patients with FE is associated with a different local and systemic inflammatory pattern; and 3) the inflammatory and immune characteristics of COPD are modulated by the intestinal microbiome. The project is based on bronchoalveolar lavage (BAL) for sampling lung microbiome, and includes analysis of regional variability (intrapulmonary) and temporal variability. The project will also assess the correlation between BAL samples obtained from the proximal airway (oral cavity, oropharynx and sputum), and the representation of lung microbiome in them. A cohort of COPD patients (n = 50 FE; n = 50 NE) and healthy subjects (n= 30), matched by age, sex and tobacco consumption. Respiratory secretion samples will be collected in clinical stability samples, with resampling in a quarter of the participants at 6-9 months. Coordinator Project: Bacterial and fungal microbiota will be determined by 16S rRNA and ITS amplification and sequencing. Virome and functional metagenomics will be analyzed in a quarter of the participants. Subprojects: Regional variability in the lung, local and systemic inflammatory response, and the relationship between the intestinal microbiome and inflammatory and clinical characteristics of the disease will be determined. The integration of the results will be performed using network medicine methodologies. The results of this project will help to understand the pathogenesis of COPD and its exacerbations with the final aim to identify new therapeutic targets.
In patients with clinical symptoms of respiratory infection, rapid identification of cases requiring antibiotic therapy is crucial to avoid development of multiple resistant bacteria. Identification of local acute-phase reactants can help assess the host's response to bacterial infection at the injury site. Here, the investigators developed an affordable, stable, feasible, and accurate diagnostic tool based on a locally produced protein with specific binding affinity to polysaccharides. The investigators further evaluated the ability of the novel test strip to rule out pneumonia.
