Filter by:Vitamin D can be made in the skin by exposure to sunlight and can be found in certain foods. Vitamin D levels are alarmingly low in many North American children. Several health issues have been linked with low vitamin D. These include colds caused by viruses and asthma attacks. However, no study has determined whether vitamin D supplementation can reduce the risk of these conditions in young children where they are most common and most severe. The goals of this study are to determine whether wintertime high dose vitamin D supplementation of preschoolers can prevent colds and asthma attacks. The investigators also aim to work out how much money would be saved by the health care system and society if preschoolers were routinely supplemented with Vitamin D during the winter. The investigators believe that preschoolers receiving 'high dose' vitamin D supplementation during the wintertime will be less likely to have colds, asthma attacks, and low vitamin D levels and will be less likely to use the medical system and keep their parents away from work.
Background: Therapeutic outcomes of leukotriene receptor antagonist (LTRA) vary in asthmatics，and there's not an ideal and simple way for prediction at present. Objective：To investigate whether leukotriene D4 bronchial provocation test (LTD4-BPT) could be an indicator of actual therapeutic outcome of LTRA. Methods：A single centre, open-labeled trial was performed in 32 asthmatics with positive LTD4-BPT result for a month. All subjects were categorized according to airway responsiveness to leukotriene D4（PD20FEV1-LTD4）. Subjects received montelukast therapy (10mg, once per night), and reassessment was performed (3~5) days after withholding LTRA. The primary end-point was the difference in monthly PEFR. Secondary endpoints included the difference in FENO, PD20FEV1-LTD4, PD20FEV1-MCh, pre-test FEV1, ACT score, AQLQ symptom score, week 4 PEFmax and PEFmin as compared with week 1, gradual decrease in the use of salbutamol and the days without using salbutamol.
Phenotype characterization of shortness of breath of pediatric emergency room patients by objective wheeze and cough monitoring improves diagnostic and severity assessment accuracy and correlates with overall patient outcomes.
This is a double-blind, placebo-controlled dose-ranging study of KHK4563 to evaluate the effect of multiple-dose subcutaneous administration of KHK4563 on the annual asthma exacerbation rate in adult subjects with uncontrolled, suspected eosinophilic asthma.
Leukotrienes are potent inflammatory molecules produced mainly by mast cells, eosinophils, monocytes/macrophage and neutrophils in response to allergic or inflammatory stimuli. GSK2190915 is a high affinity 5-lipoxygenase-activating protein (FLAP) inhibitor that attenuates the production of leukotrienes, through the blockage of the first committed step in the leukotriene pathway, 5 lipoxygenase (5-LO) activation. GSK2190915 has been shown to be an in vitro inhibitor of human organic anion transporting polypeptides 1B1 and 1B3 (OATP1B1 and OATP1B3), hence there is a potential for a pharmacokinetic drug-drug interaction with OATP1/ B1 substrates such as the anti-lipidemic rosuvastatin. This study will evaluate the effect of repeat oral dosing of GSK2190915 (30milligram (mg) and 100mg) on the steady-state pharmacokinetics (PK) of rosuvastatin (10 mg). In addition, the study will evaluate the safety and tolerability of this combination when co-administered to healthy, adult volunteers in two cohorts.
The purpose of this study is to assess the late and early asthmatic response after an allergen inhalation challenge in adults with mild atopic asthma after receiving multiple doses of tezepelumab (AMG 157), as well as the safety, tolerability, immunogenicity, and pharmacokinetics of multiple doses of tezepelumab in adults with mild atopic asthma.
Asthma has an especially great impact on poor urban children and their families. In addition to higher asthma prevalence and morbidity, those in low SES urban areas are at risk for low health literacy. Low health literacy is associated with poorer asthma outcomes. The provision of a written asthma action plan has been shown to help with asthma management and to reduce hospitalizations and ER visits. Poor urban families who may have low literacy may need an alternative asthma action plan to convey the treatment plan. This pilot study proposes to investigate whether a plain language asthma action plan can improve parent understanding and adherence with medication instructions, compared to standard written materials, among parents of children with asthma. This is an RCT in which parents of children with asthma will be randomized to either receive a pictogram-based low literacy asthma action plan, or a standard action plan (AAAAI), to examine whether those who receive the low literacy plan have improved asthma action plan knowledge when presented with a hypothetical scenario. A second part of the study is to examine whether providers who are given the pictogram-based low literacy asthma action plan will be more likely to counsel about certain aspects of asthma management (eg. need for daily medications even when sick, spacer use, confusion between everyday and rescue inhaler)compared to providers who receive use a standard action plan (AAAAI). This is an RCT in which pediatric providers are randomized to counsel a hypothetical patient using the pictogram-based action plan or the standard action plan (AAAAI).
This study aims to observe the therapeutic effect of leukotriene modulator montelukast alone or combined with inhaled corticosteroid(ICS) on cough variant asthma(CVA). The investigators hypothesize: 1. Cough score and cough reflex sensitivity will be improved after treatment with montelukast, inhaled corticosteroid/β2 agonist(ICS/LABA), and two combinations. 2. Combination of leukotriene modulator and inhaled corticosteroid/β2 agonist may have better efficacy when compared to montelukast, corticosteroid/β2 agonist alone while MON, is comparable to symbicort.
This current study aimed to demonstrate the effectiveness of the addition of CPAP to the current conventional therapy in terms of airway obstruction improvement in acute asthma patients.
The purpose of this study is to determine whether the addition of tralokinumab to standard asthma medication is effective in the treatment of adults with asthma
