Filter by:The purpose of this study is to investigate the bronchial inflammation and hyperresponsiveness after oil supplementation. Before and after oil supplementation the investigators measure decrease in lung function after exercise-challenge in a cold chamber and increase of inflammatory markers in the blood.
This project is an observational study for the Italian language validation of the CARATKids questionnaire investigating the asthma and coexisting allergic rhinitis control in children. 113 patients with concomitant asthma and allergic rhinitis followed up from at least 3 months will be enrolled for the validation process at outpatient clinic of Pediatric Allergology & Pulmonology (PAP) of Respiratory Disease Research Center (RDRC) within the Institute of Biomedicine and Molecular Immunology (IBIM) of the National Research Council (CNR) of Palermo (RDRC-IBIM CNR), Italy. The study will be completed in two medical examination, within 3-6 weeks of each other. CARATKids questionnaire, VAS (Visual Analogic Scale) and C-ACT (Children Asthma Control Test) will be filled by each patient. The main outcome is the Italian language validation of the CARATKids questionnaire investigating the coexisting asthma and allergic rhinitis control in children.
The investigators have developed a tool to facilitate asthma self-management in children, the electronic-AsthmaTracker (e-AT). The e-AT changes ambulatory asthma care delivery to a new model that is continuous and proactive, focusing on prevention and control, rather than reactive and focusing on management of asthma attacks. The e-AT 1) engages parents in weekly monitoring of their child's chronic asthma symptoms, 2) guides parents to recognize warning signs of asthma attacks in order to prompt appropriate interventions and timely visits to Primary Care Providers, and 3) provides Primary Care Providers with real-time, objective patient data to assess the effectiveness of asthma therapy and prompt adjustments. In a preliminary study of the paper-based version of the AT, frequent users had significantly fewer emergency department (ED) and hospital visits. Parent comments during the e-AT pilot testing revealed that the tool was useful in helping them manage their child's asthma and were interested in assessing the tool's effectiveness and in identifying and addressing barriers to their sustained use of the e-AT. Improving asthma control in children will be facilitated by broad e-AT dissemination, and by identifying and addressing critical factors that contribute to parent sustained participation in self-management. The investigators propose to assess the effectiveness of the new ambulatory care model supported by the e-AT and conduct an e-AT process evaluation, assessing barriers and facilitators of sustained parent use. The investigators will engage parents throughout this study to identify and address themes that matter to them. The target population is children with persistent asthma, ages 2-17 years. The investigators have engaged 10 parents since conception of this project, from the planning to design and validation of the paper-AT, and the design and pilot testing of the e-AT. Input from parents was received through 3 iterative focus groups (one for the paper-AT and 2 for the e-AT) and facilitated discussions to inform the development of this proposal including research objectives and outcome measures. In addition, the investigators have recruited other key stakeholders for whom the results of the research will be relevant.
The purpose of this study is to examine whether a parental training program using group-based Acceptance and Commitment Therapy for childhood asthma care, is effective in reducing the children's unplanned health care services utilization and asthmatic symptoms.
The purpose of this study is to determine the prevalence and severity of asthma in patients with HIV. To determine the immunological phenotype of HIV-infected patients with asthma.
This trial objective is to assess whether doubling the daily intake of vitamin D improves serum vitamin D levels and serves as primary prevention of respiratory infections and asthma in premature infants. This is a prospective randomized (1:1) double-blinded trial. The study population will be randomized into two groups (1:1): - Intervention Group - 800 IU of Vitamin D once daily - Control Group - 400 IU of Vitamin D once daily Patients will be followed up for one year after randomization for serum Vitamin D levels and respiratory morbidity.
A 2-group healthy volunteer study to compare a breath actuated inhaler (BAI) and a pressurised metered dose inhaler (pMDI) with and without spacer.
The purpose of this study is to see if the use of a machine called CPAP will help children with asthma breathe better. CPAP is a machine that produces airflow to help people with breathing problems. To use it, you will wear a mask connected by a hose to the CPAP machine. We believe that use of CPAP may be a treatment for children with asthma.
The main objective of the trial is to explore if any of the biomarkers assessed are sensitively linked to the asthma phenotypes. This would potentially alone or in addition to other clinical or biofluid markers indicate if and how asthma endotypes are linked to phenotype such as eosinophilic, neutrophilic, or paucigranulocytic phenotypes. Further exploratory markers will be analysed for better understanding of physiological levels of proteins and markers playing a role in regard to disease characterization in asthma. As a basis for further development of a biomarker for asthma, The sponsor plans to conduct this exploratory biomarker trial to determine levels and reference ranges of biomarkers potentially associated with asthma phenotypes. The trial aims at generating a panel of serum biomarkers that can be evaluated in subsequent interventional studies. The longitudinal design will be used to ascertain stability and test-retest reliability.
Stable Asthma patients (GINA 1-2) stay 6 days in a row for 4 hours per day in a hypoxic chamber simulating 2800m above sea level. Study participants will be blinded to the treatment given and divided into a hypoxic and a sham group (about 360m above sea level). Effects of this intermittent hypoxia on the asthmatic inflammation of these patients will be measured. The primary endpoint is the change in forced exhaled nitric oxide (FeNO) before and after the study. Secondary endpoints include blood parameters, lung function testing and questionnaires.
