Filter by:Treating and caring for people with long term conditions accounts for a substantial proportion of health care resources. Self-management is advocated as a mechanism that can empower service users with long term conditions to choose healthier options and also transform the relationship between service user and caregivers from one in which the former is a passive recipient of care to one in which they are an active partner in decision-making. Interstitial lung disease (ILD) is one such long term condition. Patients with ILD often express concern about the lack of information on possible rehabilitation programmes and other services that could potentially improve self-management of the disease. In addition, there is a general perception about a lack of co-ordination between health care professionals especially in relation to referral to services for comprehensive management of the disease. Therefore, the needs of patients with ILD and their carers, and possible gaps in service provision need to be explored further. In this study, the investigators propose to explore the needs of ILD patients from all types of ILD and all stages of severity and to also involve carers and clinicians. The investigators will conduct three focus groups for patients and carers and six one-to-one interviews with clinicians to explore perceptions about service gaps and needs in two ILD centres in South and North London, UK. This study will provide valuable information to develop the building blocks of a self-management resource and will enable the investigators to make it specific to the different types of ILD.
This study aims at identifying bird proteins useful for diagnostic tests to determine the cause of Bird Fancier's Lung (BFL).
The investigation serves the identification of pulmonary hypertension (PH) among patients with hypersensitivity pneumonitis (HP). The exact prevalence of PH in HP is unknown. Data from South America indicate that the prevalence of pre-capillary PH amongst patients with HP is higher than 20%. There are no reliable data from Europe so far. According to the investigators previous analysis, more than 400 HP patients have participated in pulmonary rehabilitation at least once in the past 10 years at Klinikum Bad Gleichenberg (Rehabilitation Center for Agricultural Workers in Austria). This collective of patients is to be invited to participate in the study. A diagnostic algorithm will be applied in the clinical trial, in the case of clinical suspicion the diagnosis of PH will be confirmed by right heart catheterization. Besides the determination of the prevalence of PH in patients with HP the investigators aim to assess the reliability of non-invasive methods (e.g. Echocardiography, ECG...) to predict PH.
Patients are being offered participation in this pirfenidone trial because They have been diagnosed with fibrotic hypersensitivity pneumonitis (FHP), a type of interstitial lung disease (ILD). This is a disease where scarring of lung tissue occurs as the result of inhaling substances called antigens. These antigens can be substances such as molds, chemicals or dust. As a result of this scarring the lungs are is not able to move oxygen into the bloodstream to reach other organs. Currently over 1400 subjects have been treated with pirfenidone in 15 clinical trials. This drug has been approved by the Food and Drug Administration (FDA) for use in Idiopathic Pulmonary Fibrosis, a different type of ILD, but requires special permission for use in your condition. The use of pirfenidone has not been approved for the treatment of FHP. It is considered experimental treatment in this study.
Stop exogenous allergic alveolitis (EAA) in childhood: healthy into adulthood - a randomized, double-blind, placebo-controlled, parallel-group study to evaluate prednisolone treatment and course of disease. The hypothesis of the study is that the treatment with placebo will not be inferior in terms of Forced Vital Capacity (FVC) improvement than treatment with systemic steroids after 6 months treatment.
The diagnosis of idiopathic interstitial pneumonia (IIP) is based on computed tomography (CT) imaging, whereas lung function studies are used for staging and follow up. Lung diffusing capacity for carbon monoxide (DLCO) is generally reduced but weakly correlated with the severity of CT-determined fibrotic process. A possible explanation of this finding is that DLCO is relatively insensitive to changes in alveolar membrane diffusive conductance (DMCO). Lung diffusion capacity for nitric oxide (DLNO) was strongly correlated with CT-determined amount of fibrosis/honeycombing in both usual and non-specific interstitial pneumonias. Moreover. Both DLNO and DMCO were below the lower limit of normality even in patients with small amount of fibrosis. Measurement of DLNO may provide a more reliable assessment of fibrotic changes than DLCO because it better reflects DMCO.
Hypersensitivity pneumonitis (HP) is a syndrome with variable clinical presentation in which lung inflammation is caused by inhalation of specific organic antigens or low molecular weight particles in previously sensitized individuals. Systemic symptoms may or may not be present. Chronic HP represents the final stage of the disease, caused by prolonged exposure to a particular antigen, leading to pulmonary fibrosis. In chronic HP, pulmonary function tests (PFTs) commonly present a restrictive ventilatory pattern, with decreased diffusion of carbon monoxide (DLCO). Some patients can also have obstructive disorders with expiratory flow limitation, due to obstruction of the small airways typically caused by bronchiolar involvement in this pathology. However, PFTs are relatively insensitive for detecting small airway involvement when there is concomitant interstitial fibrosis. First, conventional PFTs may be normal in patients with small airway involvement, since they contribute to less than 30% of the total airway resistance. In addition, damage to the small airways in HP is generally occurring parallel to areas of focal fibrosis - even when small airways are involved, these regions can be completely ignored, since they are excluded from ventilation. In summary, traditional PFTs are not sufficiently sensitive to detect diffuse small airway involvement in these diseases. In these cases, other functional tests, such as forced oscillation technique (FOT) and high resolution computer tomography (HRCT) scans of the chest with expired studies, could be used for this purpose. This will be a cross-sectional study, which will include the following evaluations in 28 patients with HP recruited from our clinic: - Clinical variables: (A) demographic and anthropometric data; (B) Clinical data: Onset of symptoms and time of diagnosis C) Dyspnea score: D) Smoking: * Current or former smoker * Smoking history (number of cigarettes smoked per day and for how long); - Spirometry with forced and slow maneuvers before and after bronchodilator (salbutamol); - Plethysmography to measure lung volumes; - Diffusion capacity of carbon monoxide (DLCO); - High-resolution chest CT with expiratory scans; - Six-minute walk test; - Cardio-respiratory test using a maximal incremental treadmill. - Forced oscillation technique (FOT).
The Chronic Hypersensitivity Pneumonitis (HP), is an inflammatory disease who has an evolution to develop progressive interstitial fibrosis, who cause the death of the patient. Actually HP has been treated with Prednisone and occasionally with Azathioprine, but unfortunately the treatment with these drugs have not an effective result to treat the interstitial fibrosis. Pirfenidone has been studied over the world for the treatment of Fibrotic diseases, with positive results, and due to the Pirfenidone mechanism of action has anti-inflammatory and anti-fibrotic properties, the investigators propose to evaluate the addition of Pirfenidone to the actual treatment with Prednisone and Azathioprine in the treatment of patients with Pulmonary Fibrosis secondary to a Chronic Hypersensitivity Pneumonitis.
The purpose of the study is to determine if the clinical course of pneumonia is more severe when both, bacterial and viral pathogens are find as possible causative agent and how does it affect treatment.
Community acquired pneumonia (CAP) is associated with a high in-hospital mortality. Standardization of diagnostics and adherence to sepsis bundles in the emergency department (ED) are associated with reduced mortality in patients with sepsis. Investigators examined whether the introduction of standardized care bundles and check lists in the ED are associated with a reduced mortality rate in patients hospitalized for CAP. This is an observational trial. The investigators retrospectively analyzed performance indicators of 2819 consecutive patients with CAP admitted to the Nuremberg Hospital, Germany, from 2008 to 2009. At the turn of the year, implementation of CAP care bundles took place including interprofessional education, checklists and institutionalized feedback. Primary endpoint was in-hospital mortality of CAP patients. After the implementation of CAP care bundles in the ED, mortality of affected patients was significantly lower in 2009 compared to 2008. This study should demonstrate that the implementation of a standardized CAP care bundle in the ED is associated with a risk reduction in affected patients. Standardization of diagnostic and therapeutic processes in the ED therefore improves the outcome of patients hospitalized for CAP.
