Filter by:Based on studies in China, Iceland, the Netherlands and Italy it seems that children are less affected by SARS-CoV-2 infections and play a lesser role in the dissemination of the SARS-CoV-2 virus. It is unclear to which extend this is due to lesser exposure or an inherent decreased susceptibility to become infected. The low reported number of cases in children can be partially explained by the lower testing rates in the pediatric population. To get insight in the transmission of SARS-CoV-2 virus in school-aged children it is necessary to compile data on infection of SARS-CoV-2 virus in the child and (pre-)adolescent population. The main objective of this study is to determine the sero-prevalence and sero-conversion of antibodies against SARS-CoV-2 in a sample of school-aged children (primary and secondary school) in Belgium at different time points. Additionally this study will gain insight in the incidence of SARS-CoV-2, the proportion of asymptomatic infections with SARS-CoV-2 and the role of COVID-19 infection in household members. It will give us the possibility to investigate potential risk factors for infection. The study population includes primary and secondary school children from two predefined age groups (8-9 and 13-14 years old). These two groups are chosen because studies have shown more pronounced symptoms of infection and disease depending on age and because transmission dynamics also vary by age. The study population will be recruited in all Belgian schools including Brussels-Capital, Flemish and Walloon Region (including the German speaking community). The study is a prospective cohort study. In total there will be 3 testing points with 3 months between each point. The sample size calculation indicated the inclusion of 41 randomly selected primary and 41 secondary schools and in each school 20 randomly selected pupils of the defined age groups. Parents/legal child caregiver will complete a questionnaire at each of the testing points providing basic socio-demographic characteristics (at baseline only) and risk-behavior and health characteristics including presence of symptoms during the time since the previous testing point (at each of the testing points). The questionnaire will be completed through a secured online application during the same week as the child had the saliva sample for serological testing taken. Saliva samples will be sent to the Sciensano laboratory for serological analysis. The child's parent/legal caregiver will be informed of the serological result. Study data will guide the Belgian policy makers in their advices to limit circulation of SARS-CoV-2 in Belgium and more specifically in their advice on measures for school-age children. This data might also be used to guide health authorities that have to decide on vaccination strategies once a vaccine is available; to decide whether children should be included for vaccination to create herd immunity or not.
COVID-19 is a viral respiratory and systemic disease that has been rapidly spreading globally since the first cases were reported in December 2019 and has now become pandemic. The causative agent of COVID-19 was identified as a novel coronavirus named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, first designated as 2019-nCoV). The disease manifestations of COVID-19 can range from mild, self-resolving respiratory disease to severe pneumonia, ARDS, multiorgan failure, and ultimately death. In early reports, the mortality rate among patients admitted to hospital and with confirmed SARS-CoV-2 infection was reported to be between 4 and 15%. Although the disease can afflict all age groups, elderly patients and patients with underlying comorbidities such as high body mass index, hypertension, diabetes, cardiovascular disease, or cerebrovascular disease are at risk of developing severe disease and dying. There are currently no etiologic treatments for COVID-19, and efforts are underway to identify therapeutics that could be effective in controlling this disease.
According to different projections, the COVID-19 outbreak currently happening in France and worldwide could result in millions of deaths in the absence of efficient therapies. The COVID-19 causative agent, the SARS-CoV-2, is a virus leading to respiratory system infections in human and for which there is currently no vaccine or treatment scientifically validated in clinical studies. In that context, therapeutic human neutralizing antibodies targeting the SARS-CoV-2 envelop glycoproteins and which enable inhibition of the viral replication represent an innovative therapeutic alternative with great potential. These antibodies are also critical tools for vaccine development. Simultaneously, CHUGA researchers coordinate with each other to set up a collective biological collection to achieve others objectives such as biomarkers identifications.
This is a phase 1, randomized, double-blind, placebo-controlled, dose escalation study to evaluate the safety, pharmacokinetics, and immunogenicity of ADM03820 administered as IM injections in healthy adults for the prevention of COVID-19.
This study is a Phase I/II clinical study in healthy adults designed to assess the safety, tolerability, and immunogenicity of receiving 2 IM injections of Covigenix VAX-001/-1b, 28 days apart. Covigenix VAX-001/-1b is a plasmid DNA vaccine that expresses key antigenic determinants from SARS-CoV-2 and uses Entos Pharmaceuticals' Fusogenix PLV platform. The phase I part of this study was completed in Canada. The phase II part of the study will be completed in Burkina Faso, Senegal and South Africa.
The current COVID-19 pandemic is the biggest global healthcare challenge in the last century, and the number of cases in the next 12 months is likely to increase. There is currently no proven treatment, chemoprophylaxis or vaccine against COVID-19, which exhibits a wide clinical spectrum from asymptomatic carriage to mild upper respiratory tract infection, severe viral pneumonia to acute respiratory distress syndrome and death. Key workers are at high risk of exposure highlighting the need for effective preventative strategies. SARS-CoV-2 is a positive-sense single-stranded enveloped RNA virus which transmits via droplets, aerosols and direct contact, to reach their target naso- and oropharyngeal epithelial cells through initial electrostatic interactions to cell surface heparan sulphate (HS) proteoglycans. Carrageenan mimics cell surface HS, thereby trapping the virus to allow mucociliary clearance and has demonstrated anti-viral activity in-vitro and in a number of common cold clinical trials when administered as a nasal spray. ICE-COVID a randomised, double blind, placebo-controlled phase III trial of the prophylactic efficacy of iota-carrageenan nasal and throat spray in preventing COVID-19 illness in at risk healthcare professionals. Participants (n=240) will be randomly allocated to either the treatment arm (verum Coldamaris plus, 0.12% iota-carrageenan plus 0.04% Kappa-Carrageenan in 0.5% saline) or placebo (Coldamaris sine, saline 0.5%) arm. The study's primary objective is the prevention of COVID-19 infection, confirmed by PCR swab or documented seroconversion. Secondary objectives are to determine if carrageenan sprays reduce the clinical severity of COVID-19 and symptomatic acute respiratory infection of other aetiologies (non-SARS-CoV-2).
The purpose of this research study is to determine if high-frequency, rapid turn-around SARS-CoV-2 surveillance testing with this assay is feasible and able to be optimized to enable isolation and follow-up diagnostic testing. This test will be performed at various locations in the Madison, Wisconsin area using a mobile laboratory or standard lab space for processing. Saliva samples can be collected and processed at these locations or participants can self-collect at home and drop their samples off at designated locations for same day processing. Up to 10000 participants will be recruited for this study.
There is an urgent need to evaluate effective treatments for COVID-19 patients. Melatonin has significant anti-inflammatory and antioxidant properties and it lacks of side-effects. This randomized controlled trial seeks to evaluate the efficacy of intravenous melatonin in reducing mortality in Covid-19 patients in the ICUs.
The current standard of care for diagnosis of Severe Acute Respiratory Syndrome associated Coronavirus -2 (SARS-CoV-2 ) infection involves sample collection to be prepared and measured via real time-polymerase chain reaction (RT-PCR). This process is often time consuming depending on the level of automation within the laboratory processing the samples. In many cases, sample turn-around times can take hours to several days. A rapid assay that does not require the sophisticated laboratory equipment and techniques could provide a significant advantage to the way practitioners screen and ultimately treat patients. Moreover, the collection of samples from the nasal nares should prove useful and less invasive. The study aims to validate the use of nasal swabs and also to validate the antigen test using nasal swabs.
"This is a prospective, single-center specimen collection study. Subjects 18 years of age or older who do not have symptoms of COVID-19 will be enrolled. Two nasal swab samples and one saliva sample will be collected from each subject. The saliva sample will be tested with the COVIDSeq Test and one nasal swab will be tested with an EUA approved COVID test. The other nasal swab sample will be stored and a subset (approximately 250 specimens) will be tested with the COVIDSeq Test. Results of all testing will be provided to the sponsor for statistical analysis. Results from the comparator EUA test will be provided to the collection site investigator or designated collection site study staff. No medical treatment, guidance on treatment decisions, nor medical care will be provided. "
