Evaluation of Bronchial Inflammation in Allergic Bronchopulmonary Aspergillosis (ABPA)

Cystic Fibrosis,

Chronic bronchial inflammation is an important clinical feature in cystic fibrosis. Approximately 10% of patients with cystic fibrosis suffer from Allergic Bronchopulmonary Aspergillosis. In addition airway inflammation in patients with cystic fibrosis (CF) plays a major role in progression of CF lung disease. In patients with mild disease (Vital capacity >75%) airway inflammation is often under diagnosed. Severity of allergy against Aspergillus fumigatus will be examined using radioallergosorbent test and skin Prick-test. Subsequently, in patients with established sensitization (RAST ≥ 0.35 IU/mL) a specific bronchial provocation with Aspergillus will be performed. In addition, exhaled nitric oxide,carbon monoxide, exhaled air temperature and inflammatory cells in sputum is measured. 24 hours after bronchial allergen provocation, exhaled NO, CO, air temperature, and bronchial responsiveness is determined and a second sputum obtained. This study is designed to characterize patients with CF and sensitization against Aspergillus fumigatus in an early stage to prevent pulmonary complications of ABPA. In addition sputum cytokine profiles in CF patients with mild and moderate disease may be different in patients without and with involvement of small airway disease (SAD).

PET/CT Guided Antifungal Stewardship in Invasive Pulmonary Aspergillosis

Aspergillosis and Haematological Malignancy

OPTIFIL is a pilot prospective multicenter study based over the hypothesis that the normalization of the functional imaging 18F-FDG-PET/CT during the Invasive pulmonary aspergillosis (IPA) could occur earlier than that of conventional imaging. This study evaluates the therapeutic response through a systematic 18F-FDG-PET/CT at week 6. The latter response will be correlated with the kinetics of selected biomarkers including antigens (galactomannan, β-D glucans), circulating Aspergillus DNA and anti-Aspergillus host response markers in addition to the conventional imaging tools obtained at weeks 6 and 12.

Immunocompromised HostInvasive Pulmonary Fungal Infection2 more

Background: Fungal infections of the lung (pneumonia) can be caused by molds, such as Aspergillus and Zygomycetes, but these causes are often difficult for a doctor to diagnose. Early and accurate diagnosis of these infections can help doctors to select the correct medicines for proper treatment. A number of methods are used to diagnose fungal pneumonia. Ones that are commonly used in clinical practice include radiographic imaging (chest X-rays and computed tomography (CT) scans), blood tests, and cultures taken from fluid from the lungs (broncho-alveolar lavage (BAL) fluid). Other new methods may improve the diagnosis of fungal pneumonias. These methods include tests that can detect DNA from the fungal germ in blood and BAL fluid of some patients with these infections. Objectives: To help develop better and more accurate methods of diagnosing fungal lung infections. To detect fungal DNA and chemicals in the bloodstream and BAL fluid of immunocompromised patients with pneumonia. Eligibility: - Immunocompromised patients who are currently enrolled in another NIH protocol and who have a CT scan that shows a possible fungal infection of the lung. Design: Researchers will review patients' existing medical records and CT scans, and current pneumonia treatment plans. Patients will provide blood and BAL samples for the duration of their treatment for pneumonia, as required by researchers. Additional CT scans will not be performed, except as part of existing treatment plans.

Invasive Pulmonary Aspergillosis

The purpose of this study is to determine whether inhalation with aerosolized amphoterin B 10mg/d is more effective than aerosolized amphoterin B 2mg/d to reduce the incidence of invasive pulmonary aspergillosis.

Lung MRI and Allergic Broncho-pulmonary Aspergillosis in Cystic Fibrosis

Pulmonary Cystic FibrosisABPA

In this diagnostic study, the aim is at evaluating the diagnostic accuracy of MRI (Magnetic Resonance Imaging) to detect allergic broncho-pulmonary aspergillosis in patients with cystic fibrosis.

Diagnosis of Invasive Pulmonary Aspergillosis (IPA) in Critically Ill Patients

Survival After IPARisk Factors for IPA

Invasive pulmonary aspergillosis (IPA) is difficult to diagnose and remains a cause of high morbidity and mortality in critically ill patients in the ICU. Accepted diagnostic protocols for haemato-oncological patients are not applicable for critically ill patients in ICUs. Definitive discrimination between aspergillic colonisation and IPA often depends on the clinical experience of the treating physician, evaluating clinical signs, co-morbidities, and course of the disease. Life saving treatment with the first line antimycotic Voriconazol (Vfend®) can only be initiated after diagnosis of IPA. In this prospective clinical trial the investigators aim to structure, optimize and fast track the diagnostic pathway of IPA in critically ill patients treated in our ICU-department.

Mechanisms of Immune Tolerance and Inflammation in Patients With Cystic Fibrosis With ABPA

Cystic FibrosisAllergic Bronchopulmonary Aspergillosis

The goal of this study is to identify the immunological factors that influence a patient's response to the presence of the fungus Aspergillus fumigatus (A. fumigatus) in the lungs. In patients with cystic fibrosis (CF), this fungus is not known to cause damage to the lungs, but some patients respond with an allergic reaction that may cause wheeze, cough, or difficulty breathing. Approximately 230 patients will be enrolled with an additional 60 people who do not have CF and who do not have a history of asthma to serve as a comparison group.

Invasive Pulmonary Aspergillosis and Severe Influenza

AspergillosisInfluenza1 more

Invasive pulmonary aspergillosis (IPA) has been reported in critically ill patients with influenza infection with a highly variable incidence between 1 to 21%. Studies investigating IPA in critically ill patients with influenza infection suffer limitations in their methods. It remains unknown whether patients with influenza are more at risk of IPA than other patients hospitalized in intensive care unit and whether patients with influenza who develop IPA have specific risk factors for this infection. Our study aims to determine the incidence of IPA in a large multicenter cohort and to identify risk factors for IPA in these patients.

Clinical and Prognostic Comparisons Between Invasive Pulmonary Aspergillosis With or Without Invasive...

Invasive Pulmonary AspergillosisMorality

Invasive tracheobronchial aspergillosis (ITBA) is an uncommon, but severe clinical form of Invasive Pulmonary Aspergillosis (IPA) in which the fungal infection is entirely or predominantly confined to the tracheobronchial tree. In view of the limited data concerning critically ill patients admitted to the intensive care unit (ICU) with severe influenza associated with ITBA, the investigators decided to evaluate the differences between the clinical presentations of two invasive infections: ITBA and IPA without tracheobronchial involvement (No ITBA).

Invasive Aspergillosis

Diagnosing invasive pulmonary aspergillosis (IPA) remains a challenge in patients (pts) with hematological malignancies. The clinical significance of testing bronchoalveolar lavage (BAL) samples both with polymerase chain reaction (PCR) and Aspergillus galactomannan (GM) ELISA is unclear, and the BAL cutoff for GM has not been clearly defined yet. Using a validated nested PCR assay and a GM ELISA, we prospectively examine BAL samples from hematological patients at high risk of PA.
