Active clinical trials for "Asthma"

This study will investigate the interaction between GSTP1 / TNFa polymorphisms and passive smoking in children with asthma/wheezing. Contemporary second hand-smoke exposure will be confirmed by laboratory testing.

This study raises two main hypotheses: 1) Asthmatics patients who present with bronchial hypersecretion differ phenotypically from asthmatic patients without hypersecretion and 2) mucins in asthmatic patients with hypersecretion of bronchial mucus and the expression of TLRs differ from non-mucus hypersecretory asthmatics patients.

There is a need for people to take part in research studies to learn more about diseases and how to treat them. The Registry for Asthma Characterization and Recruitment 2 (RACR2) will create a database of participants with asthma and nasal allergies, or risk factors for these conditions, who are potentially eligible for future Inner City Asthma Consortium (ICAC) trials. The registry database will include assessments of various asthma and allergy characteristics to achieve a more efficient, selective recruitment of these participants for other protocols.

The TRACK ("Test for Respiratory and Asthma Control in Kids") questionnaire is a validated instrument to evaluate the control of respiratory symptoms in young children. The TRACK questionnaire was developed in English and a version in Portuguese is not available or validated, purpose of the present project.

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.

Physical activity is mandatory to the optimal development and health of children. The presence of asthmatic manifestations may influence the comportment of children and its family toward exercise and practice of sports. There no scientific argument to advice a reduction of physical activity in asthmatic children, but previous studies showed that physical activity is reduced in asthmatic children. The aim of this observational study is to evaluate the existing factors leading to this reduction of physical activity in asthmatic children and their families.

This observational study aims at developing and validating a simple questionnaire to be routinely applied in the clinical practice, for the evaluation of the quality of life in children with concomitant asthma and allergic rhinitis. The study consists of two phases: Phase 1: Development of the RAPP-children questionnaire starting from the validated RHINASTHMA-children questionnaire. Phase 2: Administration and validation of the RAPP-children questionnaire. 150 children with concomitant asthma and allergic rhinitis will be followed-up for one month. Both at baseline and after one month, the RAPP children and several other standardized questionnaires will be administered.

Patients' satisfaction with their asthma medication devices is usually decided by using properly designed questionnaires. These questionnaires are to be used to evaluate patients' opinion, which is considered very important for the selection of a device. The Feeling of Satisfaction with Inhaler (FSI-10) is a self-completed questionnaire designed to assess the patient opinion regarding the satisfaction and usability of the inhalers irrespectively of the drug used. It consists of 10 question each with 5 possible responses on a 5-point Likert scale scored from 5 to 1, respectively. The total score can range between 10 and 50. The higher the score, the higher the feeling of patient satisfaction from the inhaler.

Moderate and severe asthma bronchiale is treated by fixed combination (budesonide/formoterol or salmeterol/fluticasone) in the Czech Republic. There is a hypothesis that doctors should prescribe to each patients per year: six units of fixed combination budesonide/formoterol, or seven units of fixed combination budesonide/formoterol in approach SMART, or twelve units of fixed combination salmeterol/fluticasone. With regard to current prices the treatment by fixed combination budesonide/formoterol should cost less. The investigators do not have any data about real life utilization of fixed combination in asthma treatment in Czech Republic The investigators propose to conduct a non-interventional multicentric retrospective epidemiological study looking into the patients records kept by specialist - allergists and pulmologists. Retrospective data for eligible patients will be reviewed by participating investigators, physicians taking care of their patients, and recorded in the electronic CRF. Only patients who have been treated for asthma bronchiale (classification of severity - moderate or severe persistent asthma) with fixed combination for at least one year could be included into the study. There are no scheduled visits for any patient participating in the study.

The rationale for conducting this study is to explore potential clinical and peripheral biomarkers in subjects requiring daily medium to high dose inhaled corticosteroids for persistent asthma
