Active clinical trials for "Asthma"

The purpose of this study is to assess if in steroid naïve asthmatic children with elevated baseline exhaled nitric oxide, treatment with inhaled steroid and normalization of exhaled nitric oxide level results in restoration of the bronchodilator response to deep inhalation.

Pin1 is activated in asthmatic airways, increasing cytokine mRNA stability and eosinophil survival. This study is designed to test whether the Pin1 enzyme regulates TLR/IL-1R signal pathways in multiple cells in asthma.

The overall goal of this proposal is to better understand the basis of structural airway changes in severe asthma and how asthma exacerbations may contribute to their progression over time. The investigators propose to study a well-characterized cohort of adult and pediatric subjects with asthma using a multidisciplinary state-of-the-art approach. We hypothesize that severe asthma exacerbations, in some patients, are associated with incomplete recovery and activation of airway inflammatory cells in a regional distribution. The end result is a more permanent and less reversible airway obstruction that is a prominent feature of severe asthma.

The purpose of the study to investigate whether montelukast lead to behavior problems in children with asthma.

To evaluate the comparative effectiveness of extrafine hydrofluoroalkane beclometasone (EF HFA-BDP) and other inhaled corticosteroid (ICS) therapy commonly used in the UK, specifically fluticasone (FP) and non-extrafine (NEF) BDP (CFC-BDP and NEF HFA-BDP) in a UK primary care asthma population of current smokers.

Asthma and sickle cell disease each are serious medical problems. People with asthma have difficulty breathing, wheeze (a whistling noise when breathing), cough, produce sputum or phlegm, and have inflammation (swelling, irritation, redness) and narrowing of the bronchial tubes. When a person has both asthma and sickle cell disease together, more serious medical problems can occur such as having acute chest syndrome and pain episodes more often. It is sometimes hard to diagnose asthma in a person with sickle cell disease because sickle cell disease can also cause lung problems. The purpose of this study is to see if the investigators can better understand asthma when it occurs in a person who has sickle cell disease. The investigators will do this by taking a blood, urine, and saliva sample. The blood and urine samples will be analyzed for chemicals and DNA (genes). Certain genes can cause patients to have sickle cell disease or asthma. The investigators will use the saliva sample for future studies to compare the results from the blood testing with saliva. The investigator's long-term goal is to make sure people who have asthma and sickle cell disease are getting the best asthma treatments. The investigator's hypothesis is that the analysis of the blood, urine and saliva using a method called, metabolomics, may identify a unique asthma signature in children with sickle cell disease which may lead to targeted treatments.

A Standardized Clinical Assessment Management Plan (SCAMP) has been developed and implemented at Boston Children Hospital to decrease variations in clinical practice in critical asthma therapies for children. The primary aim is to determine whether a Critical Asthma SCAMP can improve clinical outcome.

Overall Aim: To better understand the diagnostic process for prolonged respiratory events and determine the potential role of FeNO in assessing the possibility of asthma as the symptoms etiology. Study Objectives: The specific objectives of this study are to: Determine the frequency of ICS prescription for the treatment of non-specific lower respiratory symptoms. Determine the frequency of asthma diagnosis as an etiology for the non-specific lower respiratory symptoms. Explore the value of FeNO in identifying asthma as the etiology of the non-specific lower respiratory symptoms. Number of Subjects: It is anticipated that up to approximately 3,000 patients will be asked to complete the brief screening questionnaire that will be used to identify up to approximately 280 eligible patients who meet the study inclusion/exclusion criteria during a (approximately) 4 to 6 week study enrollment period. Reference Product: NIOX MINO® Duration of the participants involvement in the investigation: Single Visit Performance assessments: Fractional Exhaled Nitric Oxide (FeNO) Measurements will be performed using the NIOX MINO® device according to "Instructions for NO measurements" which will be provided to each Investigative site prior to patient enrollment. Safety Assessments: The Investigator is responsible for the detection, reporting, and documentation of events meeting the definition of an Adverse Event (AE) and/or Serious Injuries as provided in this clinical investigation plan from the time of informed consent/assent and during the study period. Criteria for Evaluation: The relationship(s) between FeNO and both the diagnosis of asthma and prescription of ICS will be explored by correlation, measures of concordance and logistic modeling.

The study design consists of a cross-sectional survey on the clinical characteristics of patients with asthma and their level of asthma control and current quality of life, and on a prospective evaluation of the rate of switch from the uncontrolled/poorly controlled condition to the status of controlled asthma. Asthma control will be based on the Asthma Control Questionnaire scoring system, that has been fully validated for use in both clinical practice and clinical trials and has strong discriminative properties which means that it can detect small differences between patients with different levels of asthma control and it is very sensitive to within-patient change in asthma control over time. Quality of life as a reflection of the control of the disease, will also be evaluated by means of the Mini Asthma Quality of Life Questionnaire scoring system.

The goal of this study is to evaluate the widespread implementation of a developmentally appropriate preventive asthma care intervention for urban teens. The School Based Asthma Care for Teens (SB-ACT) program includes two core components: 1) a trial of directly observed therapy (DOT) to allow the teen to experience the potential benefits from adhering to guideline-based asthma treatment, and 2) a developmentally appropriate Motivational Interviewing (MI) Counseling Intervention to help the teen transition to independent long-term medication adherence. The investigators hypothesize that teens receiving the SB-ACT program will 1) experience less asthma-related morbidity than an asthma education (AE) attention-control comparison group, and 2) have improved adherence, less urgent healthcare use, less absenteeism, improved quality of life, and reduced FeNO compared to AE. The investigators also hypothesize that participants receiving DOT-only will have improved asthma-related outcomes immediately following their DOT trial vs. teens receiving AE, but will not have sustained, clinically significant improvement in outcomes once the DOT phase is complete. This represents a unique opportunity to build upon existing community relationships with an innovative and developmentally focused program to improve asthma outcomes for urban teens.
