Filter by:It has been observed that certain section of patients having severe to moderate Asthma, do not benefit from oral corticosteroids and IL-5 blocking biologics. There is increasing evidence that Airway auto immunity may be responsible for this poor response to treatment. It has been seen in earlier study done at Nair lab that these patients might benefit from Dupilumab, a biologic blocking IL-13/ IL-4. IL-13/IL-4 are the cytokines responsible for increased inflammation in these Asthmatics. The hypothesis is that blocking IL-13/IL-4 will also reduce the airway auto immunity which can be measured by comparing the auto immune markers in airway at baseline (before starting Dupilumab) and 16 weeks (after 4 months of Dupilumab treatment.
The purpose of this study is to evaluate the superiority in terms of efficacy and evaluate the safety of QMF149 (indacaterol (acetate) / mometasone (furoate)) compared to budesonide in children from 6 to less than 12 years of age with asthma. - The study duration will be up to 37 weeks including an investigational treatment duration of 12 weeks and a comparator treatment duration of 12 weeks. - The visit frequency will be 3 weeks for screening, run-in and wash-out period, 6 weeks interval for visits during each treatment period, 30 days for safety follow-up.
A study evaluating efficacy and safety of repeated doses of PT027 compared to PT007 in patients with asthma and acute airway obstruction induced by repeated mannitol challenges
There is a strong case for treating diseases of both the upper and lower airways (global airways) simultaneously because they share the same inflammatory mechanisms. About 9% have chronic sinusitis (CRS) and 4% of the Danish population are diagnosed with CRS with nasal polyps (CRSwNP)) and 7-10% have asthma. CRS has a multifactorial background, with CRSwNP characterized by Type 2 inflammation, and approximately 50% with Type 2 CRSwNP also have co-morbid asthma. Well-treated CRS has an impact on asthma control, and well-treated asthma has an impact on CRS. Several studies show that patients with asthma have low adherence, but only a few if any of studies are available on adherence in CRS. Aim: To investigate the effect of systematic and structured nursing supervision in patients with CRSwNP and asthma primarily on adherence. Hypothesis and research questions: Patients with respiratory diseases can improve their adherence to their non-medical and medical treatment for CRSwNP/CRS and asthma by systematic and structured nursing supervision compared to patients who receive usual care. In a randomized clinical trial, we will investigate whether the level of adherence measured by the questionnaire MARS-5-N and MARS-5- L in patients with CRSwNP and asthma can be improved by 7 points after systematic and structured nursing guidance at baseline visit and controlled after four months - compared with those patients who have not received the above guidance. Primary outcome: is change in adherence rate measured by the MARS-5-N/L questionnaire in patients with CRSwNP and asthma can be improved by 4 points after systematic and structured nursing guidance at the initial visit and controlled after four months - compared with patients who have not received the above guidance. Inclusion Criteria: Adherence to MARS- 5 L/N ≤35 at first visit, diagnosed with asthma (with/without allergic rhinitis) at initial visit, diagnosed with CRSwNP, able to use smartphone, ACQ ≥1.2 or ACT≤15 (partially uncontrolled asthma), >18 years of age, SNOT-22 score ≥35 Exclusion Criteria: - Adherence to MARS-5- L/N >35 points at first visit,do not have smartphone, does not read/speak English, other illness requiring regular medication, pregnancy/pregnancy that started during the study, server psychological comorbidities Questionnaires: Patients must answer the following questionnaires at baseline and at 4 months follow up ESS, SNOT-22, ACQ-7, ACT, MiniAqLq, HADS, STARR-15
This is a multi-center study to evaluate fractional exhaled nitric oxide (FeNO) measured with the Vivatmo pro in adult and pediatric subjects.
This study will assess the effects of benralizumab on airway dynamics in severe eosinophilic asthma in terms of quantitative computed tomography (CT)-derived measurements of pulmonary structure and function using the Functional Respiratory Imaging (FRI) platform.
Aim: The purpose of this study was to examine the effect of health care transition-based education on transition readiness and self-efficacy in adolescents (14-18 years) with asthma through a randomized controlled experimental study that integrated the literature, model, and research on the transition from pediatrics to adult care. The research hypotheses are as follows: H0: There is no significant difference between the intervention and control groups' mean "Transition Readiness Assessment Questionnaire", "Self Efficacy Scale for Children and Adolescents with Asthma" and "Mind the Gap Scale" scores before and after the education they received on health care transition. H1: The mean "Transition Readiness Assessment Questionnaire", "Self Efficacy Scale for Children and Adolescents with Asthma" and "Mind the Gap Scale" score of the treatment group is significantly higher than the control group after the education they received on health care transition.
In asthma, the significant role of pathogenesis is chronic airway inflammation, bronchial hyperresponsiveness, and variable airflow obstruction. Asthma with irreversible or fixed airflow obstruction (FAO) is a clinical phenotype resulting from chronic airway inflammation with having longer disease duration, suggesting that airway remodeling contributes to the decline in lung function seen in individuals with asthma. Although this condition frequently occurs in patients with severe asthma, there are pieces of evidence occurring in those with mild to moderate asthma. According to previous research, low lung function, FEV1 less than 60% predicted, is a robust independent predictor of subsequent asthma attacks and other asthma outcomes, including asthma control and SABA use. In a recent study, the patients with mild to moderate asthma who received mild to medium dosed inhaled corticosteroid plus long-acting beta-2 agonist with or without asthma control showed evidence of FAO with or without bronchodilator reversibility. Therefore parasympathetic activity may be affected by FAO in those patients. The autonomic nervous system plays an essential role in asthma, especially from the parasympathetic, promoting bronchoconstriction and regulating airway inflammation and remodeling. This study hypothesizes that a cholinergic mechanism may play a significant role in FAO across patients with mild, moderate, and severe asthma. This might increase the fundamental evidence leading to early-step treatment with anti-cholinergic medication in early asthma severity driven by FAO.
The objective of this study is to investigate whether electromyography of the diaphragm during sleep in asthmatic children can be used to objectively monitor asthma control.
To design and validate a questionnaire that allows objective assessment of the level of bronchial mucus hypersecretion.
