Filter by:The purpose of this study is to determine if evidence-based guidance on follow-up care and self-management provided to PCPs and patients, respectively, reduces relapses within 90 days for acute asthma (primary outcome). Secondary outcomes will include follow-up visits with the primary care provider, patients' quality of life and cost-effectiveness indicators.
Evaluation of the frequency of limitation of activity, depending on gender and age-group, in patients with persistent asthma consulting a general practitioner
This is an open-label, randomized, cross-over, active-controlled study to evaluate the efficacy and safety effects using Meptin® Swinghaler and Ventolin® MDI in stable asthma patients.
Current asthma medicines include inhalers. A common inhaler used in asthma is called a beta-agonist (for example salbutamol). They improve asthma symptoms by stimulating areas in the human airway resulting in widening of the human airway. Although these drugs are useful after the first dose, longterm use can cause worsening asthma symptoms. Beta-blockers are the complete opposite type of medication. Just now they are avoided in patients with asthma as after the first dose they can cause airway narrowing and cause an asthma attack. New research has suggested that long term use of beta-blockers can reduce airway inflammation which can improve asthma control and improve symptoms. This research was done in asthmatic patients who didn't need inhaled steroids to control their asthma. What the investigators want to do is see if the same benefit of beta-blocker use is asthma can be seen in people who take inhaled steroids.
To investigate the efficacy of adding Inhaled Hypertonic Saline treatment (HS) for 1-6 year old children with "asthmatic" attack presenting to Emergency Department (ED). Background: In 1-6 year old children, the most common causes of acute exacerbations of asthma requiring urgent medical care are viral respiratory infections. Most of these children are not atopic and often do not respond very well to bronchodilators and steroids. Thus novel treatments are needed. HS is considered an effective and safe treatment for infants with acute viral bronchiolitis (Cochrane 2008). HS acts in the airways in several mechanisms: HS re-hydrates secretions and improving mucus rheology, reduce edema of the airway wall by absorbing water from the mucosa and submucosa, causes sputum induction and cough, which can help to clear the sputum out of the bronchi, stimulates cilial beat via the release of prostaglandin E2, breaks the ionic bonds within the mucus gel, thereby lowering the viscosity and elasticity of the mucus secretion. It is estimated that all the above HS responding elements may play a role in this viral induce wheezing. The above mentioned theoretical benefits provide the rationale for the possible treatment of viral induced acute wheezing ("asthma") attack with nebulized HS in young pre-school children presenting to the Pediatric Emergency Unit with acute (mostly viral induced) wheezing. Therefore, the purpose of the present study is to 1. Investigate the addition of frequently nebulized 5% HS/albuterol combination to standard therapy of acute asthmatic episodes presenting to the emergency department (ED) in preschool children in a prospective, randomized, double-blind, controlled fashion.
The purpose of this study is to find out the roles of two specific gene families (the chitinase gene family and the TGFB family). We hypothesize that chitinases and TGFb pathway genes will be differentially expressed in the airways of non-asthmatic subjects and subjects with asthma. We further hypothesize that genetic variants in CHIT1, AMCase, and TGFb pathway genes that show associations with asthma and related phenotypes will change the expression and/or function of the protein of these genes in the airway in several ways, including the transcript numbers for full length genes and splice variants and, for the chitinase genes, the levels of chitinase activity in airway secretions.
The hypothesis of the present study is that the prophylaxis with palivizumab to prevent the severe RS virus infection during the infancy among preterm infants may reduce the risk of subsequent recurrent wheezing in childhood. The infants born between July 1st and December 31st in 2007 with the gestational age between 33 and 35 weeks were enrolled into the study at the end of RS virus infection season, April 2008. The infants were unintentionally divided into two groups, either palivizumab treated or untreated group at the enrollment, because the timing for palivizumab prophylaxis were already ended. The study infants will be followed up until the age of 3 with recording the incidence of either parent reported or physician diagnosed recurrent wheezing. The difference of the incidence of the recurrent wheezing between the groups will be analyzed with Kaplan-Meier method.
This is a single center pilot study designed to evaluate the effectiveness of an asthma education program in the pediatric emergency department. Asthma has reached epidemic proportions. Nine million American children are affected in the United States alone. This problem has increased 75% from 1980 to 1994, with a staggering 160% increase seen in children less than five years old.1 The American Lung Association has targeted this overwhelming problem on both national and local levels. Asthma impacts American communities who differ geographically, culturally, ethnically and by lifestyle, and as a result will present with different obstacles. The primary objectives are: to determine whether this educational intervention (through interactions with a child life specialist and using the asthma based computer game) in the pediatric ED can influence children's [and care givers'] knowledge and understanding of the disease process and treatment, and to improve asthma self-management and decrease morbidity by decreasing ED use and hospitalization. A secondary objective is to introduce the Child Life Specialist as an effective asthma educator and further strengthen the health care team. The target population will be recruited from the pediatric emergency department. We anticipate this study to recruit over a one year period and have a one year follow up with an anticipated enrollment of 64 children and families. There will be three Child Life Specialist involved in this program. After consent has been obtained, the child and parent will complete questionnaires (focusing on asthma knowledge, quality of life, and perception of asthma) and then a laptop will be provided to access the asthma based computer game. During the child's ED visit the Child Life Specialist will have opportunities to open communication to address barriers or concerns, and reinforce material provided by the game. Through these interactions, the importance of communication between the child, parent and healthcare provider is highlighted. The family will be given information to access the computer game via the internet. Follow up phone calls or e-mails will occur at 6 months, 9 months, and 12 months which will entail completing questionnaires. The questionnaires uses validated questions along with questions from the material covered through this asthma education study.
Cross-over study to evaluate the effect on trough FEV1 after 4 weeks treatment with CHF5188 pMDI qd in adult patients with persistent asthma
Current therapies for the management of asthma include inhalers. Types of these medications (beta agonists), improve asthma symptoms by stimulating areas (receptors) within the human airway resulting in dilation of the human airway. Whilst these drugs are highly effectively in the immediate setting their longterm use, constantly stimulation of receptors within the airway has been associated with increased asthma exacerbations and rare cases of death. Conversely medications that block receptors within the human airway (betablockers)have been avoided in asthma. The main reason for this is because of the possible acute airway narrowing that can occur after soon after administration. However chronic use of betablockers in asthma has recently been shown to be of benefit in reducing airway inflammation which is of great importance in improving asthma control and reducing symptoms. Despite this early evidence supporting chronic use of beta blockers in asthma, there is concern in 2 major regards:their potential to cause acute airway narrowing (irrespective of longterm benefit) and the possibility that they could block the reliever action of beta agonists. The objective of this study is to establish how best to reverse the short term effects of a single dose of beta blocker. This study is designed as a single centre study, with participants attending the department on approximately 3 separate visits (including a screening visit) at approximately 1 weekly intervals.
