Active clinical trials for "Asthma"

In this study, investigators want to evaluation of the impact of benralizumab (Fasenra®, Astra Zeneca) on different cell populations, including basophils and innate lymphoid cells, and several biomarkers, such as miRNAs, cadena α dek receptor pra la interleukin % (IL5Rα) and soluble IL5Rα in patients with severe eosinophilic asthma. For this, basophil and innate cells type 2 (ILC2) populations will be monitored in different point-time of treatment: 8 week (V1), 6 months (V2) and 1 year (V3) in blood and sputum samples. Also, follow-up IL5Rα expression on a cell surface of eosinophils, basophils and ILC2 from peripheral blood and sputum of patients treated with or or without benralizumab. Determination of IL5Rα levels will be performed by flow cytometry

This study aims to assess the level of FeNO in Chinese asthma patients with respect to the different levels of asthma control over 1 year.

There are few studies about immunological explorations in COPD. Because of the complications of lung biopsies, analyses are generally made on blood samples instead of lung tissue. No study tried to classify COPD vs Asthma vs ACOS. The investigators wondered if there were differences in biomarkers between these groups. The investigators decided to open a pilot-study among COPD patients followed in Amiens-University Hospital. Each patient will be examined and a blood-test will be performed.

Chronic rhinosinusitis with nasal polyps (CRSwNP) is a condition resulting in varying degrees of nasal congestion, nasal secretion, facial pain and reduced or absent sense of smell. In Denmark an estimated 200.000 patients suffer from this condition. It affects the quality of life in a degree equivalent to chronic cardiac and respiratory conditions. CRSwNP is known to be associated with inflammation in the nose and sinuses. In some patients the inflammation is also present in the lower airway resulting in shortness of breath, chest constriction, wheezing and coughing. It follows that asthma is often seen in patients with CRSwNP. Even though the association of asthma and CRSwNP is well known it is easy to overlook the asthma further reducing the quality of life. Previous studies have found that undiagnosed asthma is present in about a quarter of patients with CRSwNP. While many of the CRSwNP patients are treated in private ENT practice alone the lack of simple diagnostic tests giving a reliable measurement of airway inflammation is a challenge in diagnosing concurrent asthma. A recent study showed measuring of fractional exhaled nitrogen oxide (FeNO) in exhaled air to be a promising diagnostic test. The concentration of this gas in the exhaled air from the nose and mouth is related to the degree of airway inflammation and can therefore be used as a surrogate measurement in a safe and easy way. With this study the investigators want to measure the concentration of FeNO in patients with CRSwNP in private ENT practices. The aim is to explore if it can be used as a screening test for asthma. The study will also screen the patients for obstructive sleep apnea (OSA). Patients will be recruited from three private ENT practices in the Capital Region of Denmark. Patients with CRSwNP will be recruited from their appointments in the ENT clinics. They will be offered inclusion in the study, and if they give an informed consent, an exhaled NO test and a thorough ENT examination including a fiberoptic examination of the upper airway will be performed. They will also be asked to fill out questionnaires on the severity of symptoms from the nose and lungs, sleep quality and their health in general. Patients will also undergo a sleep study (Cardio-Respiratory Monitoring = CRM) and tests of lung function. With signs of respiratory or sinus disease they will be referred for further investigations and treatment.

Dupilumab is a monoclonal anti-IL-4/13Rα antibody developed for severe asthma (SA). In France, mepolizumab was commercialized in February 2018. Before this date, many SA patients had reached a therapeutic dead end, with uncontrolled disease despite maximal available treatment. Upon the request of lung specialists involved in SA, French health authorities approved an early access program (temporary Use Authorization) allowing early access to dupilumab (before EMA's decision) from September 2017 to January 2018, for SA patients demonstrating unacceptable steroids side effects and/or life-threatening exacerbations, irrespective of their T2 status.The aim of this retrospective study was to describe the characteristics of SA patients included in the early access program and to assess changes in asthma control after a 12 months treatment.

Asthma is severe when it cannot be controlled with maximum-dose inhaled therapies while management of comorbidities and other precipitating or aggravating factors has been optimized. Allergic bronchopulmonary aspergillosis (ABPA) is a complex bronchopulmonary disease resulting from immunological reactions against Aspergillus Fumigatus. The development of a model of bronchial epithelium generated from patients with chronic lung disease will allow the modeling of bronchial tissue to understand the formation of these mucus plugs. This study aims to validate this model The investigators propose to verify the feasibility of obtaining and comparing two epithelia in two populations based on the following experiments: Differentiation of an Induced Pluripotent Stem cell (iPSC) clone derived from blood sample (Peripheral Blood Mononuclear Cells) of Type 2 inflammation (T2) severe asthma and Allergic Bronchopulmonary Aspergillosis (ABPA) in order to obtain differentiated bronchial epithelia in vitro.

The Severe Heterogeneous Asthma Research collaboration, Patient-centred (SHARP) is set up to harmonise severe asthma management across Europe and unravel underlying heterogeneity in a patient-centred way. Using data from national registries included in the SHARP network, this study aims to evaluate real-world use of Nucala, describe characteristics of patients prescribed with Nucala and evaluate the effectiveness of Nucala in clinically relevant endpoints.

Advisory Committee for Immunization Practices (ACIP) from the Centers for Disease Control (CDC) recommends that children (6-18 years) and adults (≥19 years old) with chronic lung condition such as asthma or cigarette smoking be vaccinated with Pneumococcal vaccine (PPSV23). The purpose of this study is to increase awareness of vaccination to late adolescents with asthma and smokers (social aspect of study), and to recommend vaccination (which is the clinical aspect). Individuals who agree to receiving vaccine will be enrolled in research to determine whether late adolescents with and without asthma (smokers) have distinctive pneumococcal vaccine response patterns and whether such patterns are associated with subsequent variance in asthma outcomes.

Validation of Structured Light Plethysmography (SLP) in patients with asthma, in patients with acute asthma; an observational study in healthy participants and during patients' clinical investigation of broncho-reversibility in the asthma groups.

Little guidance is given to physicians caring for obese adolescents with asthma, however, findings suggest that interventions designed to achieve asthma control in these patients are necessary. Because of the psychosocial factors often associated with obesity and asthma (e.g., low self-esteem, depression, and low quality of life) successful interventions should incorporate a patient-centered approach. The proposed study design is a clinic-based, randomized controlled trial (RCT) in teens with a history of asthma and who are overweight or obese.
