284 Clinical Trials for Various Conditions
The objectives of this study would be to determine the most effective treatment for children with PCRS and asthma who fail medical management.
The objectives of this study would be to determine the most effective management for pediatric patients with chronic rhinosinusitis and asthma who fail medical management. The Sinus and Nasal Quality of Life Survey (SN-5), a validated tool, will be used to track symptoms of pediatric chronic rhinosinusitis. A decrease in at least 0.5 is felt to represent an improvement in symptom control. In this study, the SN-5 at one year post intervention will be the primary endpoint. Secondary endpoints include complications, revision surgery, and post operative endoscopy scores.
The purpose is to investigate the Efficacy and Safety of Symbicort pMDI 80/2.25 μg and Symbicort pMDI 80/4.5 μg, Compared with Budesonide pMDI 80 μg, 2 Actuations Twice Daily, in Children Ages 6 to \<12 Years with Asthma during 12 weeks.
Propanolol is a beta blocker which has been found to inhibit the ability of epinephrine to upregulate sickle red cell adhesion to laminin and endothelial cells in vitro. The purpose of this pilot study is to administer one dose of propanolol to children with sickle cell disease and to measure pre and post dose red cell adhesion. The hypothesis is that a single dose of propanolol will decrease red cell adhesion to laminin and endothelial cells as compared to baseline.
The primary objective of this study is to determine ex vivo the amount of fluticasone deposited onto a filter (delivered dose) interposed between the OptiChamber Diamond Valved Holding Chamber (VHC) mouthpiece and the subject's mouth during coordinated and uncoordinated actuation/inhalation maneuver.
This purpose of the study is to investigate the bronchodilating effects of 3 different dosages of formoterol given in combination with budesonide as Symbicort pMDI.
This purpose of the study is to investigate if budesonide pMDI 160 �g twice a day during 6 weeks is effective and safe in treating asthmatic children aged 6 to \<12 years

The primary objective of this study is to compare the QVAR-Easi-Breathe 100 mcg/day and QVAR-Easi-Breathe 200 mcg/day with placebo relative to changes in forced expiratory volume in 1 second (FEV1) results following 12 weeks of treatment. Secondary objectives such as daily asthma symptoms scores (per week), morning peak expiratory flow (PEF) values, nocturnal awakening and utilization of rescue medication per day also will be evaluated. In addition, an exploratory evaluation will assess the comparability of the two devices (i.e., QVAR-Easi-Breathe versus QVAR-MDI) at the same dose levels.
The purpose of this research study is to study the relationship between childhood asthma, allergies, and early-life environmental factors that may cause childhood asthma and allergies. Previous birth cohort studies have found early-life environmental factors such as allergies, pollutants, viruses and bacteria have all contributed to the development of asthma and allergies. Investigators are doing this research because there continues to be a strong need to understand the root causes of asthma and allergies. The CANOE study is an observational cohort study, which means investigators are not asking participants or participant's child to change their medications and investigators will not be giving participants or participant's child a study drug.
The primary goal of this proposal is to use an in-home, smartphone-enabled, hand-held spirometer to determine the FEV1% predicted ranges that predict the Yellow Zone threshold.
This is a pilot randomized controlled trial of lower vs. higher dose vitamin D supplementation in D-deficient asthmatic children, to determine necessary sample sizes for outcome measures in a larger multisite study, and to examine possible relationships and effect sizes between various biological markers that may be important to the pathophysiology of childhood asthma. Aims of the study are to: 1. Evaluate effect sizes for relationships between serum 25OH-vitD and omega-fatty acid (FA) biomarkers, before and after supplementation with lower or higher dose vitamin D, on immune function, and asthma severity. 2. Characterize changes in innate and adaptive immune function and inflammatory responses in asthmatic D-deficient youth at baseline and after vitD supplements, by dietary O6:O3FA status and vitD dose.
This Phase 2 study was to investigate the tolerability of unit dose budesonide (MAP0020) at three doses in pediatric volunteers with a diagnosis and history of mild-to-moderate stable asthma and evaluate the pharmacokinetic profile of budesonide resulting from inhalation aerosol delivery.
The purpose of the study is to evaluate asthma and examine the homes of children with asthma living in rural areas of the state. This study is being done to give investigators more information about the presence of allergens and endotoxin in the homes of children with asthma living in the delta region of Arkansas.
This study consists of a 3-year double-blind phase during which patients will receive atopic dermatitis (AD) treatment either with pimecrolimus cream 1% long-term management (LTM) or with a conventional corticosteroid-based treatment (1:1 ratio), followed by a 2 to 3-year open-label (OL) phase (all patients receiving pimecrolimus cream 1% LTM). At the end of the double-blind phase, the two treatment groups will be compared with respect to their efficacy in controlling AD; at the end of the OL phase, the incidence of asthma at the age of 6 years will be compared.
This is a two-arm, parallel design, randomized, controlled pilot trial comparing access to Asma Guardián, a culturally tailored multi-component app-based asthma intervention for Hispanic/Latinx school age children with asthma, to usual care.
Many children currently being hospitalized with severe asthma could potentially avoid hospitalization and be sent home if their treatment in the emergency department was more effective. The investigators will conduct a pilot trial that will lead to a larger study to conclusively answer whether a simple and inexpensive medicine, intravenous magnesium sulfate, can be used in the emergency department to prevent hospitalization for these children.
The purpose of this study is to learn more about if taking a supplement called 5-hydroxytryptophan (5HTP) can improve breathing and anxiety symptoms related to asthma. To help learn more subjects will either be assigned to a group that is taking the supplement (5HTP) or a group that is taking a placebo. This will be decided randomly. Later in the study subjects will crossover to the other group.There are 5 study visits over the course of about 12 weeks.
This study will determine whether vitamin D3 prevents severe asthma attacks in children who have a serum vitamin D (25(OH)D) level \<30 ng/ml and who are being treated with inhaled corticosteroids for asthma. Half the participants will receive vitamin D3 at a dose of 4,000 IU/day, and the other half will receive placebo.
Asthma is a leading cause of emergency department (ED) visits for children. A novel way of treating asthma is the use of positive expiratory pressure (PEP). Positive expiratory pressure works by creating pressure in the lungs to keep airways open and to clear mucus from the lungs. PEP is already used in the treatment of asthma at the investigators institution, but studies evaluating the efficacy of PEP therapy in asthma exacerbations do not exist. This study plans to learn more about the use of PEP therapy in the treatment of asthma exacerbations in children in the emergency department. Specifically, the study aims to evaluate if PEP therapy reduces the severity of asthma exacerbations in children and if it reduces the need for additional therapies and admission to the hospital. This study will be a randomized control trial comparing children who receive standard therapy to those who receive standard therapy plus PEP therapy in the treatment of asthma exacerbations. Children age 2 to 18 years presenting to the ED with moderate to severe asthma exacerbations will be included in the study. Reduction in clinical asthma severity will be measured by change in the Pulmonary Asthma Score (the respiratory severity score used at the investigators institution). The need for additional therapies and hospitalization will also be evaluated.
Near fatal asthma exacerbations are one of the most common causes of critical illness in children, accounting for approximately ten thousand intensive care unit (ICU) admissions per year in the United States. Even children with intermittent or mild baseline asthma can develop these severe exacerbations; however, there are few studies evaluating the risk factors associated with the development of near fatal asthma exacerbations in children. Inhaled β2-adrenergic receptor (ADRβ2) agonist therapy is the foundation of therapy for acute asthma and genetic variations of this receptor have been shown to affect response to ADRβ2 agonist therapy in this population. The investigators hypothesis is that a child's ADRβ2 genotype is associated with the development of a near fatal asthma exacerbation.
Parents of children with asthma must work with their child's pediatrician to ensure that their child's asthma is managed well. Asthma coaches are one way to facilitate and support the relationship between parents and pediatricians. This study will evaluate whether access to a 12-month telephone asthma coaching program for parents is an effective way to improve asthma outcomes in children.
Long-term cognitive outcome study of children who participated in randomized trials of LCP-supplemented formula during infancy.
Asthma is a common illness among children in the United States. While there are many known causes of asthma, including tobacco smoke, pollen, dust, or other allergens, the exact cause of asthma in some individuals remains unknown. This study will examine the role that specific dietary factors and body mass index (BMI) play in the development of childhood asthma.
The purpose of this study is to determine whether the addition of budesonide inhalation suspension (BIS) to the standard therapy of albuterol, ipratropium bromide, and systemic corticosteroids (SCS) for moderate to severe asthma flares in children reduces asthma severity more rapidly than standard therapy alone.
Oral montelukast is helpful in chronic asthma. The purpose of this pediatric study was to investigate whether the addition of oral montelukast to standard therapy for acute asthma exacerbations results in further improvement in breathing function over three hours.
The purpose of this study is to determine whether early childhood exposure to common allergens (substances that can trigger allergies and asthma) can prevent the development of asthma in children at high risk for developing the disease.
