Filter by:The COVID19 pandemic is having an immeasurable impact on the economy and on morbidity and mortality. Knowledge and scientific evidence about this disease is advancing rapidly, but it is not yet known whether asthmatic patients suffering from COVID19 have an exacerbation of asthma, or whether this viral infection has an impact on control and lung function in the short to medium term. The aim of this study is to define the changes that occur in these two parameters in asthmatic patients suffering from COVID19. To this end, asthmatic patients who have suffered a SARS-CoV-2 infection and who have required an emergency consultation or hospitalisation will be collected in a pneumology consultation and matched by age, sex and severity of asthma with a group that has not suffered the same. Both will be followed for one year, and lung function will be tested at six months and exacerbations and changes in ACT during the following year. These data are intended to improve the available knowledge on the impact of IDVC19 on asthma patients with a view to making appropriate recommendations, prevention and treatment adjustments in line with the results obtained.
Patients with severe or difficult-to-treat asthma represent a small amount of total asthmatic patients, but weight on the national health system for the costs of disease management. Chronic rhinosinusitis with nasal polyposis, which the Italian severe/uncontrolled asthma registry reported with a prevalence of 30%, represents a comorbidity that significantly impact lung function and asthma control in severe asthma. Recent evidence indicates that there is a consistent heterogeneity regarding mucosal alterations present in subjects with nasal polyposis involving different pathways: inflammatory cells, remodeling, T cell activation, local IgE production, alteration induced by interactions between microorganisms and epithelial cells.
This is a Phase 3b, multicenter, randomized, double-blind, parallel group, placebo-controlled study designed to investigate the potential effect of tezepelumab (210 mg subcutaneous [SC] every 4 weeks [Q4W]) on antibody responses following seasonal quadrivalent influenza virus vaccination in the fall/winter 2021-2022 in the USA.
The goal of this study is to evaluate the implementation of the Coach McLungsSM shared decision making (SDM) intervention into primary care across a large healthcare system. Coach McLungsSM is a virtual evidence-based asthma intervention with built-in asthma education and clinical decision support. All asthma patients aged 5-17 who attend these practices will be assessed for uncontrolled asthma. Asthma exacerbations attributed to emergency department visits, hospitalizations, and oral steroid use, will be evaluated to serve as surrogate measures for patient-centered asthma outcomes.
The investigators propose a pragmatic randomized clinical study, consisting of two groups, the control group with health education and the intervention group with teleconsultation. The research team comprises pharmacists, students, and professors who work in a pharmaceutical service of secondary health care linked to the public university. The investigators will conduct the study exclusively remotely, following the patients for six months. The research team will implement and structure an ambiance to adapt the face-to-face pharmaceutical consultation into the pharmaceutical teleconsultation. The evaluated outcomes, in both groups, will be the scores of the Asthma Control Test, the Asthma Quality of Life, and the hospitalization rate and admission to urgency/emergency services.
The bulk of the morbidity and mortality related to asthma is during periods of acutely increased symptomatology called 'exacerbations'. Roughly half of asthma sufferers experience such an exacerbation each year. Most of these events are triggered by viral infections, usually the common cold virus (rhinovirus). A key part of the body's defence against viral infections is to produce antiviral proteins called 'interferons', which have a myriad of effects to stop viruses. Previous work on cells taken from volunteers with asthma and healthy controls and infected with rhinovirus in the lab suggests interferon production is impaired in asthma. However when human volunteers with asthma are infected with rhinovirus, high levels of interferon are found a few days later - along with high numbers of virus. Whether the high virus numbers are the result of an initially weak interferon response, with subsequently unchecked viral replication leading to exaggerated interferon levels, is unknown as no one has measured interferons early in infection. By infecting volunteers with asthma and healthy controls with rhinovirus at a known time, only done in a handful of centres worldwide, we will be able to measure interferons within hours of infection and well before symptoms develop.
The long-term goal is to improve the care of patients with asthma. The overarching objective of this pilot grant is to test the feasibility, acceptability and potential clinical utility of deploying a mobile-health intervention to improve asthma surveillance.
This is a retrospective observational study drawing on data from the Brigham and Women's Home Hospital database. Sociodemographic and clinic data from a training cohort were used to train a machine learning algorithm to predict patient deterioration throughout a patient's admission. This algorithm was then validated in a validation cohort.
Listening sessions: The research team will collect qualitative data from the listening sessions (focus groups) using a semi-structured iterative focus group guide.
To investigate whether high-dose vitamin D supplementation may have a beneficial effect on secondary prevention in preschool children (1-5 years of age), with respiratory infections being the primary cause of acute exacerbations with asthma-like symptoms.
