Filter by:The local and systemic manifestations that affect patients with Chronic Obstructive Pulmonary Disease (COPD) cause severe dyspnoea and limitation of functional capacity, leading to impairment in the performance of activities of daily living (ADL). The combination of aerobic and resistance training, for both upper limbs (UL) and lower limbs (LL), appears to be the physiologically most complete resource for improving quality of life and increased survival of these patients. Therefore, the aim of the study is to assess the impact of aerobic and resistance training of different intensities on the performance and dyspnoea during activities of daily living and prediction of mortality in patients with COPD. There will be include 45 COPD patients with moderate to severe obstruction, aged between 50-80 years of both gender. All patients will undergo to the following assessments and reassessments: history and anthropometric data, Scale London Chest Activity of Daily Living Scale (LCADL), modified Medical Research Council (mMRC), BODE index, test peripheral muscle strength, mobility and balance tests, 6-minute walk test (6MWT), Circuit ADL Test, 1 repetition maximum (1RM) and Incremental Cardiopulmonary Testing (ICPT). Patients will be randomly divided into two groups and undergo to the treatment program will consist of sessions lasting approximately 1 hour, three times a week for 12 consecutive weeks, totaling 36 sessions. All patients will undergo general stretching and aerobic training on a cycle ergometer with the intensity between 70-80 % of the maximum load achieved in ICPT. After aerobic training, a group of patients will achieve a protocol of low-intensity resistance training (LI-RT), with emphasis on gaining muscle strength, and the other group will be submitted to a protocol of high intensity (HI-RT), aiming greater gain in muscle strength. The calculation of the intensity of training will be conducted by the 1RM test. After the training protocol, it is expected to find improved performance and dyspnoea during activities of daily living and reduction of BODE index for both groups, however, it is expected that the group of low-intensity resistance training presents greater benefits in ADL.
In cigarette smokers that are HIV+, one of the most common HIV-associated non-AIDS conditions is the accelerated development of chronic obstructive pulmonary disease (COPD), a disorder associated with significant morbidity and mortality. Based on the knowledge that COPD in smokers starts in the small airway epithelium, this study is focused on examining the hypothesis that the accelerated development of COPD associated with HIV infection results, in part, from an interaction of HIV directly on the small airway epithelium or through infection of cellular components of the immune system, with mediators released by these immune cells evoking premature biologic aging of the small airway epithelium. By identifying the early events in the pathogenesis of the HIV-associated accelerated COPD in smokers, we aim to identify biologic targets to which pharmacologic therapies could be addressed.
Background: COPD exacerbations add considerably to patients' burden because they: (1) cause frequent hospital admissions and relapses or readmissions, (2) contribute directly to the death of many patients, either during hospitalization or shortly thereafter, (3) cause patients significant stress, prolonged physical discomfort, disability and dramatically reduced quality of life, (4) consume the majority of the resources available to manage this chronic condition, (5) frequently progress to a severe stage warranting hospitalization before any abortive treatment is instituted, and (6) may hasten the progressive loss of lung function, a steady decline that is a cardinal feature of COPD itself. Hence, investigations of new therapies to treat COPD patients who are hospitalized with a severe exacerbation are desperately needed. Objective: To test the feasibility of roflumilast to decrease all cause readmission and mortality 180 days after hospitalization for acute COPD exacerbation. Methods: Parallel-group, prospective, randomized, double blind, placebo-controlled trial of roflumilast 500 ug daily vs. placebo in approximately 100 hospitalized AECOPD patients. Inclusion Criteria. Primary diagnosis of AECOPD; admission to the hospital <12 hours; patient age >40, < 80 years old; cigarette smoking > 10 pack-years. Exclusion Criteria. Prior diagnosis or high suspicion for asthma; pulmonary edema, pneumonia, interstitial lung disease or significant bronchiectasis; intubated and mechanically ventilated at the time of evaluation; active liver disease, or transaminase elevations (> 3xULN); history of heavy ethanol use; history of suicidal behavior ≤ 2 years or suicidal ideation ≤ 6 months prior to enrollment; pregnant or lactating females. Those on the following excluded medications: P450 inducers and CYP3A4 inhibitors or dual inhibitors that inhibit both CYP3A4 and CYP1A2 simultaneously
Difficulty falling asleep, staying asleep or poor quality sleep (insomnia) is common in people with chronic obstructive pulmonary disease. Insomnia is related to greater mortality, with four times the risk of mortality for sleep times < 300 minutes. Insomnia is also related to greater morbidity, with 75% greater health care costs than people without insomnia. However, insomnia medications are used with caution in COPD due to potential adverse effects. Common features of COPD such as dyspnea, chronic inflammation, anxiety and depression also affect insomnia and can interfere with therapy outcomes. While cognitive behavioral therapy for insomnia (CBT-I), a therapy that provides guidance on changing unhelpful sleep-related beliefs and behavior, is effective for people with primary insomnia and people with other chronic illnesses, the efficacy and mechanisms of action of such a therapy are yet unclear in people with both insomnia and COPD. The objective in this application is to rigorously test efficacy of two components of insomnia therapy - CBT-I and COPD education (COPD-ED) - in people with coexisting insomnia and COPD, and to identify mechanisms responsible for therapy outcomes. The central hypothesis is that both CBT-I and COPD-ED will have positive, lasting effects on objectively and subjectively measured insomnia and fatigue. The rationale for the proposed study is that once the efficacy and mechanisms of CBT-I and COPD-ED are known, new and innovative approaches for insomnia coexisting with COPD can be developed, thereby leading to longer, higher quality and more productive lives for people with COPD, and reduced societal cost due to the effects of insomnia. The investigators plan to test our central hypothesis by completing a randomized controlled comparison of CBT-I, COPD-ED and non-COPD, non-sleep health education attention control (AC) using a highly efficient 4-group design. Arm 1 comprises 6 weekly sessions of CBT-I+AC; Arm 2=6 sessions of COPD-ED+AC; Arm 3=CBT-I+COPD-ED; and Arm 4=AC. This design will allow completion of the following Specific Aims: 1. Determine the efficacy of individual treatment components, CBT-I and COPD-ED, on insomnia and fatigue. 2. Define mechanistic contributors to the outcomes after CBT-I and COPD-ED. The research proposed in this application is innovative because it represents a new and substantive departure from the usual insomnia therapy, namely by testing traditional CBT-I with education to enhance outcomes.

Study to investigate safety, tolerability and effect of multiple dosing with AZD 4721 and/or with AZD 5069
The CHROMED project focuses its investigation on the applicability of an integrated solution for a pathological condition which: a) is very prevalent in ageing patients and b) severely impairs quality of life: COPD with other typical comorbidities such as congestive heart failure and sleep disordered breathing. A specific ICT platform in combination with a set of innovative devices will be used to collect and process useful clinical data at the patient's home and used to optimize their medical treatment. To evaluate the impact of this solution, an international multi-centric randomized control trial will be implemented in five European regions: United Kingdom, Sweden, Estonia, Spain and Slovenia, representing different social and organizational contexts in Europe.
This study purpose is to further study the profiles of glycopyrronium (NVA237) and tiotropium during the first hours after dosing and their impact on pulmonary function, COPD symptoms and ability to perform daily activities by the patient.
