Chronic rhinosinusitis (CRS) is a multifactorial disease characterized by persistent symptomatic inflammation of the mucosa of the nose and paranasal sinuses, with (CRSwNP) or without (CRSsNP) the presence of nasal polyps. It affects 5 to 12% of the general population. CRS is often associated with asthma, which has a prevalence of 4% in the general population, reaching 30%-70% among patients with CRS. The current standard clinical evaluation of patients for both diseases has two main components: a subjective one (self-assessment provided by the patient), based mainly on the PROMs (Patient-Reported Outcome Measures) questionnaire, and an objective one (formulated by the clinician). Questionnaires present accuracy and response rate problems that have been investigated in the literature, finding that short questionnaires, incentives, personalization of questionnaires as well as repeat sending strategies or telephone reminders have a beneficial impact on the quantity and quality of responses. Today there are many new channels provided by technology. Among them, AI chatbots have been used in a variety of healthcare domains such as medical consultations, disease diagnosis, mental health support and, more recently, risk communications for the COVID-19 pandemic, and can offer a better way to collect questionnaires. At the same time, the recent technical solution of new non-invasive techniques for RFID radio frequency identification devices allows subjective reports to be accompanied with objective reports. The PRECISION project aims to evaluate systems for home monitoring of chronic rhinosinusitis (CRS) and asthma, two highly prevalent chronic diseases. The frequent association between the two pathological conditions is a further argument in support of the rationality of a common approach. As regards the collection of PROMs, three acquisition channels will be compared: i) AI Chatbots; ii) PhoneBot; iii) Mobile application. Data will be analyzed in relation to patient profiles to define the quality and quality of response. Regarding objective evaluation, the project will investigate the efficiency of objective remote airflow measurements for both upper (CRS) and lower (asthma) airways using dedicated non-invasive systems based on RFID technology.
Antidepressants, particularly selective serotonin reuptake inhibitors (SSRIs), such as escitalopram are widely used for mood and anxiety disorders. However, they have also been explored, with promising findings, for a variety of disorders outside of psychiatry. Clinical studies of SSRIs in depressed people with asthma were associated with decreased asthma exacerbations and improvement in asthma control. In this study, the number of asthma exacerbations will be assessed as the primary outcome measure, in patients using escitalopram vs. placebo.
This is a single-center, randomized, double-blind, placebo-controlled, phase 1, single-ascending-dose study to evaluate the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of IBI3002 in healthy participants and mild to moderate asthmatics. Subjects will be randomly assigned to different dosages of IBI3002 and matched placebo groups. The entire trial cycle includes a 4-week screening period, 1-day treatment period and 5-week follow-up period.
Asthma is a worldwide health problem and is one of the most common chronic diseases of childhood in most countries. Symptoms begin before the age of 5 years in 80% of children with asthma, but the diagnosis is not always easy. The National Asthma Education and Prevention Program (NAEPP) expert panel recommends spirometry testing for children over 5 years of age. Spirometry measurements include forced vital capacity (FVC) and the forced expiratory volume in first second (FEV1). Airflow obstruction is defined as FEV1 reduced to less than 80 percent predicted and an FEV1/FVC ratio of less than 0.85 (85 percent). Reference values are based on age, height, sex, and race. Forced expiratory flow between 25 and 75 percent of vital capacity (FEF25-75) less than 65 percent correlates with reversible airflow obstruction in children with normal FEV1 and may be a useful measure in this subgroup. In the spirometry test, FEV1, FVC, FEF 25-75% values are valuable for the follow-up of asthma. While the FEV1/FVC ratio is above 80% in healthy children, it may decrease below 75% in diseases such as asthma. Likewise, FEV1 and FEF can be found to be low in 50-75% of asthma patients. In addition, these values can be used to determine the effectiveness of the inhaler given with the nebulizer given during the attack. Spirometry should be performed before and after administration of a bronchodilator to assess for reversibility (bronchodilator response [BDR]) even in children with a normal baseline FEV1 because many of these children will still have a BDR (both within the normal range and sometimes also supranormal) after treatment. Significant reversibility is indicated by an increase in FEV1 of ≥12 percent from baseline after administration of a short-acting bronchodilator. This definition for BDR positivity was established primarily in adults. An increase in FEV1 of ≥8 percent may be a better definition for BDR in children. Inhaled short-acting beta-2 agonists, particularly albuterol (salbutamol), are the standard emergent treatment for acute asthma exacerbations in all patients based upon adult data. It is recommended to be given every 20 minutes in case of need for repeated doses in mild and moderate asthma attacks. Different types of nebulizers can be used for inhaler therapy; they can convert drugs into vapor form with sound waves, compressed air or by using electrical energy. While compressor nebulizers convert the liquid drug into aerosol form with compressed air, mesh nebulizers convert the drug into aerosol form with the vibrations they create with the help of electrical energy. Mesh nebulizers are more effective than other types of nebulizers, and the amount left in the chamber is less than other models, and it can decompose the drug into smaller particles and reach the more extreme branches of the lung. In our study, the investigators aimed to determine which nebulizer type is more effective by comparing the effects of mesh nebulizer and compressor nebulizer on spirometry test in children presenting with asthma attack. Thus, the investigators planned to find the most comfortable and effective method for patients by determining the appropriate nebulization technique for patients.
The goal of this interventional study is to examine the effect of asthma flare-up clinic follow-up in adult subjects after an asthma flare-up. This study aim to answer the following questions: 1. Does a follow-up in a flare-up clinic improves disease outcomes? 2. Does a follow-up in a flare-up clinic improves disease management? Participants in the intervention group will take part in a structured follow-up at the asthma flare-up clinic at three time points. Each visit will include questionnaires, pulmonologist examination and consultation, laboratory tests and spirometry. The control group will undergo phone-call follow-up with a research coordinator in similar time frames as the intervention. Researchers will compare the two groups to see if the clinic follow-up affects the study outcomes.
Bronchial asthma may present with symptoms other than the commonly reported complaints (cough, chest tightness, shortness of breath and wheezing). Less common symptoms include chronic or recurrent productive cough, inspiratory dyspnoea or recurrent pneumonia. Children presenting with these symptoms are often diagnosed with asthma bronchiale and benefit from antiasthmatic management.
Non-adherence to controller therapy is one of the main reasons of poor asthma control. Adherence to medication in different studies range between 30 and 70% . Several factors related to the disease, to the patient, treatment or physician- patient relationship
this study aimed to compare characters in pulmonary function of patients with cough variant asthma and chronic cough and establish a diagnostic model.
To compare the effects of moderate intensity interval training and sprint interval training on patients having chronic asthma.
