ABSTRACT
Background: The current coronavirus disease 2019 (COVID-19) pandemic began in Ireland with the first confirmed positive case in March 2020. In the early stages of the pandemic clinicians and researchers in two affiliated Dublin hospitals identified the need for a COVID-19 biobanking initiative to support and enhance research into the disease. Through large scale analysis of clinical, regional, and genetic characteristics of COVID-19 patients, biobanks have helped identify, and so protect, at risk patient groups The STTAR Bioresource has been created to collect and store data and linked biological samples from patients with SARS-CoV-2 infection and healthy and disease controls. Aim: The primary objective of this study is to build a biobank, to understand the clinical characteristics and natural history of COVID-19 infection with the long-term goal of research into improved disease understanding, diagnostic tests and treatments. Methods: This is a prospective dual-site cohort study across two tertiary acute university teaching hospitals. Patients are recruited from inpatient wards or outpatient clinics. Patients with confirmed COVID-19 infection as well as healthy and specific disease control groups are recruited. Biological samples are collected and a case report form detailing demographic and medical background is entered into the bespoke secure online Dendrite database. Impact: The results of this study will be used to inform national and international strategy on health service provision and disease management related to COVID-19. In common with other biobanks, study end points evolve over time as new research questions emerge. They currently include patient survival, occurrence of severe complications of the disease or its therapy, occurrence of persistent symptoms following recovery from the acute illness and vaccine responses.
ABSTRACT
BACKGROUND: Clinical presentations of coronavirus disease 2019 (COVID-19) among children with asthma have rarely been investigated. This study aimed to assess clinical manifestations and outcome of COVID-19 among children with asthma, and whether the use of asthma medications was associated with outcomes of interest. METHODS: The Global Asthma Network (GAN) conducted a global survey among GAN centers. Data collection was between November 2020 and April 2021. RESULTS: Fourteen GAN centers from 10 countries provided data on 169 children with asthma infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). COVID-19 was asymptomatic in 58 (34.3%), mild in 93 (55.0%), moderate in 14 (8.3%), and severe/critical in 4 (2.4%). Thirty-eight (22.5%) patients had exacerbation of asthma and 21 (12.4%) were hospitalized for a median of 7 days (interquartile range 3-16). Those who had moderate or more severe COVID-19 were significantly more likely to have exacerbation of asthma as compared to those who were asymptomatic or had mild COVID-19 (adjusted odds ratio (adjOR) 3.97, 95% CI 1.23-12.84). Those who used inhaled bronchodilators were significantly more likely to have a change of asthma medications (adjOR 2.39, 95% CI 1.02-5.63) compared to those who did not. Children who used inhaled corticosteroids (ICS) did not differ from those who did not use ICS with regard to being symptomatic, severity of COVID-19, asthma exacerbation, and hospitalization. CONCLUSIONS: Over dependence on inhaled bronchodilator may be inappropriate. Use of ICS may be safe and should be continued in children with asthma during the pandemic of COVID-19.
