Active clinical trials for "Asthma"

The aim of this study is to assess and compare efficacy and safety of BI 54903 at doses of very low dose twice daily (b.i.d) and low dose once daily (evening dosing) and placebo over an 12-week treatment period in asthmatic patients aged 12 to 65 years inadequately controlled on short acting beta-2 agonist (SABA) therapy alone as demonstrated by a decrease in forced expiratory volume in 1 second (FEV1) (not less than 10 %, and equal to or less than 25%) and an Asthma Control Questionnaire (ACQ-6) of not less than 1.5 at time of randomisation.

This study is intended to determine the safety and tolerance of regadenoson in subjects with asthma or chronic obstructive pulmonary disease.

Young inner-city children with asthma have the highest emergency department (ED) visit rates. Relying on the emergency department for asthma care can be a dangerous sign of poorly controlled asthma. This research will focus on whether having a specialized asthma nurse join the family at a child's doctor visit after an ED visit for asthma to make sure the child and parent keep the follow-up appointment and have the nurse remind the child's doctor to prescribe preventive asthma medicines and an asthma action plan for home (PAAL intervention) will result in young children with asthma having fewer days with wheezing and cough. The investigators hypothesize that: Significantly more children receiving the PAAL intervention will attend greater than 2 non-urgent visits and greater than 6 refills for the child's anti-inflammatory medications over 12 months when compared to children in the control or standard asthma education group. Children in the PAAL intervention group will experience less morbidity and caregivers will experience increased quality of life compared to children in the control of standard asthma education group.

Asthma is a clinical syndrome that is well recognized by health care practitioners, yet asthma pathogenesis still remains poorly understood. Asthma affects approximately 20 million Americans, who suffer around 5,000 deaths annually. More than 70% of people with asthma also suffer from allergies. Although many advances in understanding the pathophysiology of asthma have been made in the past few decades, more studies are necessary to achieve a more thorough understanding of asthma at the cellular and molecular level. The majority of murine models suggest asthma and "allergic" responses involve activation of Th2 cytokine pathways, including IL-4 and -13. Similarly in humans, several lines of evidence support a large role for Th2 adaptive immunity. These include the large majority of asthmatic patients with atopy; the measurement of increased amounts of Th2 cytokines, including IL-4 and IL-13 in the airways and sputum of mild asthma; and most recently, the observed efficacy of anti-IgE therapy in "allergic" asthma. However, other data, including the large numbers of subjects with atopy and no asthma, suggest Th2 adaptive responses are insufficient to explain many aspects of asthma. Whether and how innate and adaptive immune pathways interact in human asthma is not clear, with few studies beginning to address these interactions in vitro and in vivo. For this reason, the investigators of this study would like to prospectively enroll patients with known asthma and follow them through an asthma exacerbation, while treating them with a standardized protocol. Over six week's duration, the investigators would like to study patients by collecting physiologic data such as spirometry, and biologic material in the form of sputum, nasal scraping, venous blood, exhaled breath and sputum. It is our aim to fully characterize the impact of the prostaglandin/cycloygenase/eicosanoid pathway as it relates to asthma exacerbation and recovery. Completion of this study in human asthma may provide new mechanistic insights into how relationships between innate and adaptive immune responses influence the course of an asthma exacerbation. The information obtained from this research and the corresponding studies may lead to innovative medical therapies and insight into the role of the epithelium and its interactions with both innate and adaptive immunity.

Asthma disproportionately affects minorities, but few studies have evaluated interventions to improve asthma outcomes in minority children.The purpose of the study is to determine whether Parent Mentors (PMs) are more effective than traditional asthma care in reducing minority children's asthma morbidity, costs, and use of services, while increasing families' quality of life and parental self-efficacy.

The purpose of this study is to determine the efficacy of a multifactorial intervention with weight reduction, behavioural therapy, and physical exercise on the severity and control of asthma in obese children.

Obstructive sleep apnea (OSA) is a common but under-diagnosed form of sleep disordered breathing (SDB). Asthma is a common disease with rising prevalence, which continues to pose significant morbidity and costs. In spite of considerable progress in our understanding of asthma, a large number of individuals with asthma continue to have symptoms and subsequently, have a poor functional status, poor quality of life and increased health care costs. In many cases no apparent cause is found and optimal therapy does not achieve its goal. While recent data suggests that OSA is common in severe asthma, the prevalence of OSA and its predisposing factors have not been studied.

This is an ancillary study conducted as part of the BASALT trial [NCT00495157]. The overall hypotheses are: 1) an indirect airway challenge procedure using mannitol can safely characterize asthma phenotypes, predict asthma control and exacerbations, predict responses to interventions, and perform more specifically than a direct methacholine challenge and; 2) PX27 pore function in whole blood correlates with measures of airway hyperresponsiveness induced by methacholine and/or mannitol challenges
