Filter by:This is an observational, Italian multi-center, retrospective cohort study with enrollment visit on patients suffering from severe eosinophilic asthma who started benralizumab in the Sampling Program or as per normal clinical practice in Italy.
Clinical trial to demonstrate whether, in patients with moderate asthma, to treat with IC / LABA a medium dose, but not controlled, to achieve a similar degree of control by making a progressive increase of that treatment (CI / LABA a high dose) versus switching to fluticasone / Formoterol K-Haler at medium dose, under conditions of usual clinical practice.
Objective: To compare the effectiveness of inspiratory muscle training (IMT) and incentive spirometer on ventilatory functions in post-menopausal asthmatic women. Participants and methods: A total of forty postmenopausal women suffering from asthma, their ages ranged from 50 to 60 years old, and their body mass index of the patient don't exceed 30kg/m2. They were recruited from patient chest clinic in Kasr -El- Ainy Teaching Hospital, Cairo University, Egypt.
Investigators will test the superiority of Superiority Trial of Fluticasone-Vilanterol as needed in mild asthma compared to standard of care
Allergic asthma is a complex and heterogeneous disease caused by excessive responses to inhaled allergens. Current medication, including corticosteroids and bronchodilators, does not act on the origin of inflammation but rather combats symptoms, leaving many patients uncontrolled. Airway epithelium is critical for the initiation and progression of asthma pathology. We will include a 52 subjects divided over two groups: ongoing asthma (26 patients) and non-asthmatic healthy controls (26 subjects) in a cross-sectional study. All subjects will be extensively clinically characterized including respiratory symptoms/questionnaires, in- and expiratory CT-scans, and parameters of large and small airway function and inflammation. In addition, blood and nasal epithelial brushes will be obtained to study the genetic and epigenetic mechanisms of asthma. Finally, bronchoscopy with bronchial biopsies and brushes will be performed under conscious sedation. Bronchial biopsies from both patient groups will be used for single cell transcriptional analysis.
TARGET-RWE is a 10-year, international, longitudinal, observational study of patients with chronic disease designed to specifically address important clinical questions that remain incompletely answered from registration trials. The protocol will follow a master protocol design in which a shared study infrastructure supports progressive development of the registry across the spectrum of chronic diseases.
Neutrophilic asthma (NA) is the least known severe asthma phenotype. It is associated with more exacerbations, worse control and impaired lung function. One of its possible etiologies is bronchial infections. The study of bronchial microbiology and its relationship with exacerbations is a new line of research. Objectives: 1) To analyze bronchial microbiome in patients with AN and non-neutrophilic (ANN), with frequent exacerbations and without exacerbations. 2) To relate the presence of bronchial infections with differences in the microbiome. 3) Correlate the characteristics of the microbiome with other evidence used in exacerbations. Methods: Prospective study involving 40 non-smoking asthmatics without bronchiectasis (20 with AN and 20 with ANN). Of these, 10 in each group will have frequent exacerbations (>2 rounds of systemic steroids in the last year, of >3 days each) and 10 non- frequent exacerbations. AN will be defined as >65% neutrophils in stable phase sputum. All patients will have two stable visits in which clinical variables, asthma control, lung function and induced sputum samples will be collected (for analysis of bronchial inflammatory cell count and for the study of the microbiome by 16 subunit rRNA). Specific Immunoglobulin A (IgA) for Chlamydia Pneumoniae will be determined. In exacerbations, sputum samples will be collected for culture and nasopharyngeal smears for the study of major respiratory viruses and bacteria by multiple polymerase chain reaction.
Double-blind, randomized, two-way cross-over study with two treatment periods. 28 subjects with asthma will be randomized in 1:1 ratio to treatment A) Indacaterol/Mometasone 150/160 μg once daily and treatment B) Indacaterol/Glycopyrronium/Mometasone 150/50/80 μg once daily for period 1. For period 2, subjects will be crossed over to the other treatment arm. Subjects will be screened during the first visit. After inclusion subjects will be seen for 3 visits during the Run-in period, 3 visits during treatment period 1 and 3 visits during treatment period 2. During these visits patients will be clinically characterized and exposed to allergen challenge tests.
This exploratory laboratory only study will assess alterations in immune cells in blood samples that may be responsive to an inflammatory mediator in asthma called IL-33 (Innate lymphoid type 2 cells, basophils and Th2 cells) in response to treatment with ANB020/placebo (a drug that targets IL-33, in the linked clinical trial ANB020-004). The study will involve additional 10ml blood draws on scheduled study visits in the ANB020-004 clinical trial at baseline, 1 week, 5 weeks, 18 weeks (4 visits total). Total number of subjects is 24 at the same 3 participating UK sites as the main linked clinical trial ANB020-004. Blood samples will be sent on the same day to a flow cytometry laboratory at the NIHR Leicester Biomedical Research Centre (BRC) - Respiratory. A dedicated post doctoral, trained laboratory scientist will analyse the blood samples for the required cell types using a technique called flow cytometry - this technique identifies cell surface and intercellular markers, that together provide a unique cell identity. The experiments will be supervised by a senior research scientist and flow cytometrist Professor Dave Cousins, at the University of Leicester and results of the experiments will be fed back to AnaptysBio (the linked clinical trial Sponsor). Professor Salman Siddiqui at the University of Leicester will oversee the clinical conduct of this laboratory study and act as the Chief Investigator. Professor Siddiqui is also the local site lead Principal Investigator at Leicester for the linked ANB020-004 clinical trial described below. The linked study (ANB020-004) is a Double-blind Placebo-Controlled Proof of Concept Study to Investigate ANB020 (a drug that targets an inflammatory mediator called IL-33) Activity in Adult Patients with Severe Eosinophilic Asthma. The expected duration of the study is up to 141 days. Screening period of 7-14 days and treatment and follow-up period of 127 days.
The aim of the randomized controlled study is to investigate the effects of NMES superimposed on voluntary contraction combined with patient education and exercise training program in patients with chronic obstructive pulmonary disease.
