Active clinical trials for "Asthma"

This study evaluates the initiation of inhaled corticosteroids upon discharge from the pediatric emergency room in children under 18 presenting with asthma exacerbation. Half of the patients will receive a prescription for inhaled corticosteroids in addition to standard care, and half of the patients will receive standard card alone.

Aim: To investigate the possible immune modulatory effects of allergen immunotherapy (AIT) on respiratory immunity in patients with allergic asthma (AA). Background: Allergic sensitization to aeroallergens is a common co-morbidity in asthma that is associated with more frequent and severe asthma attacks. The investigators have recently shown that patients with allergic asthma also have an increased risk of pneumonia, and hence allergy in asthma may be associated with a relative respiratory immunodeficiency. However, the increased risk was obliterated in patients treated with AIT. Methods: Patients with asthma sensitized to house-dust mite (HDM) is enrolled in a randomized, double-blind, placebo-controlled study of HDM-AIT. Patients will be scheduled for 9 visits through 8 months including, randomization to 6 months of treatment with either HDM-AIT (Acarizax/Odactra) or placebo. Primary interferons (IFN) type I and III will be investigated in human bronchial epithelial cells as the primary outcome. Secondary outcomes such as: Inflammatory cytokines, immunologic phenotype and immunohistochemistry will be investigated in bronchial biopsies, blood, bronchoalveolar lavage fluid, sputum and HDM-patch biopsies as well as a thorough respiratory and allergic evaluation. Expected outcomes: The investigators expect that, patients with AA have 1) decreased production of anti-viral type I and III IFN and that AIT increases these measures. 2) Anti-bacterial response is reduced through IL12, ß-defensin and IFN-γ and that AIT increases these measures. 3) Lastly, the investigators expect that T-cell response is dysregulated (Th1↓1/Th2↑) in patients with AA and that these findings are modulated in an immuno-protective direction after AIT. Perspectives: This project will expand our understanding of the clinical significance of allergy in asthma in a completely novel direction and show how AIT may modulate the immune response to prevent infections.

Asthma is a problem that affects many children and affects their physical health in addition to having a social and financial burden on individuals, families and healthcare systems. In our pediatric emergency department, nebulizers are still used for the management of asthma and, with the poor resources of families, they have no option of treatment at home. In this study, the investigators will compare the effectiveness of treatment through nebulizer versus metered dose inhaler and spacer in children with an acute asthmatic attack seeking medical care at the Pediatric Emergency Department of Suez Canal University Hospital.

The primary objective is to evaluate the prophylactic efficacy of REGN1908-1909 (anti-Fel d 1) administered as a single dose on day 1 in cat-allergic asthmatic patients not living with a cat in the prevention of a Controlled Cat Allergen Challenge-induced early asthmatic response (EAR) assessed by measures of lung function (FEV1) compared to placebo-treated patients. Secondary Efficacy Objectives: To evaluate the prophylactic efficacy of REGN1908-1909 administered as a single dose on day 1 in cat-allergic asthmatic patients not living with a cat, in the prevention of a Controlled Cat Allergen Challenge-induced: Allergic rhinitis and Ocular symptoms To evaluate the prophylactic efficacy of REGN1908-1909 administered as a single dose on day 1 in cat-allergic asthmatic patients not living with a cat to increase the exposure to cat allergen, measured as a product of minute ventilation and time, required to induce EAR in a Controlled Cat Allergen Challenge as compared to placebo patients Secondary Safety Objective: To evaluate the safety and tolerability of REGN1908-1909 vs. placebo in patients with cat allergen-triggered asthma

This is a randomized, double-blind, placebo-controlled, multicenter, parallel group study to compare 2 dose levels of budesonide/albuterol BDA MDI (PT027) to its components budesonide BD MDI (PT008) and albuterol AS MDI (PT007) on improvement in lung function and asthma symptoms after 12 weeks of treatment in adult, adolescent, and child subjects with symptomatic asthma currently being treated with a short/rapid-acting β2-adrenoreceptor agonist (SABA) as needed alone or with low-dose inhaled corticosteroid (ICS) maintenance therapy plus SABA as needed.

Although IV salbutamol is frequently used in children in a wide range, pharmacodynamic data are scarce. To date, there is an insufficient evidence base to guide initial and subsequent dosing recommendation for its IV use in children. Especially the need for a loading dose needs to be addressed. Therefore, pharmacodynamic and kinetic data are needed to guide initial dosing strategies of IV salbutamol in children. To assess the efficacy of a loading dose of intravenous salbutamol in children admitted to a PICU for severe acute wheeze or severe acute asthma. Efficacy is measured by the reduction in asthma score (Qureshi) at 1 hour after administration of the loading dose, compared to placebo.

A multicenter, double-blind, randomized, parallel-group comparative Phase II clinical study to assess the efficacy and safety of different doses of XC8 vs Placebo in patients with partly controlled bronchial asthma receiving stable treatment with low doses of inhaled corticosteroids with or without long-acting beta2-agonists during 12-weeks treatment period. Study design was developed by Pharmenterprises LLS, Russia in cooperation with Eurrus Biotech GmbH, Austria and FGK Clinical Research GmbH, Germany. The primary objective of the study was to evaluate the effect of different doses of XC8 on change in pre-bronchodilator forced expiratory volume in 1 second (FEV1) (% of predicted value) at Week 12 as compared to baseline at Week 0 vs. Placebo in patients with partly controlled bronchial asthma (BA).

Patients presenting to the emergency department with acute asthma exacerbation will be assigned to peak-expiratory flow rate (PEFR) guided management and non-PEFR guided management.

Asthma is characterized by airway inflammation and is manifested by acute episodes of obstruction related to loss of control of airway inflammation mostly in response to a viral respiratory tract infection .The significance of eosinophilic inflammation in asthma is well established. Late clinical reactions in asthma are associated with increase of immunoglobulin E (IgE) in serum. Serum IgE can be used as a measure of allergen provocation causing increased eosinophil activity. Serum IgE can be used to assess the exposure to environmental allergens, or decreasing presence of allergen in the environment and the need for increase or reduction of therapy. Allergen immunotherapy is defined as the repeated administration of specific allergens to patients with IgE-mediated conditions for the purpose of providing protection against the allergic symptoms and inflammatory reactions associated with natural exposure to these allergens. The aim of this work is to evaluate the effect of sublingual versus subcutaneous allergen immunotherapy as regard clinical response, serum IgE and sputum eosinophils

The project will be pursued in our respiratory, autonomic nervous system physiology laboratory (Respiratory, autonomic nervous system physiology laboratory, Department of Pneumology and Intensive Care Medicine, RWTH Aachen University Hospital). Overactivity of the sympathetic nerve activity (SNA) axis with "centrally" increased heart rate and peripheral vasoconstriction is a known phenomenon in patients with systolic heart failure (HF) and has recently been described in patients with primary lung diseases as in chronic obstructive pulmonary disease (COPD) and pulmonary hypertension (PH). Comprehensive studies investigating sympathetic drive in Asthma as one of the major pulmonary diseases are still lacking. Furthermore, the intention of this study is to determine the impact of Nasal High Flow Therapy (NHFT) on SNA and assess respiratory muscle function using state-of-the-art techniques.
