Filter by:The coronavirus disease 2019 (COVID-19) outbreak, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), emerged in Wuhan in December 2019 and has spread globally, representing a serious threat to public health. While waiting for highly effective treatments or the development of an effective vaccine, it is necessary to reactivate key economic activities that are related to leisure and culture in an environment that is safest for the participants. The use of a rapid screening test for SARS-CoV-2 viral antigens with high sensitivity could be a useful tool to detect asymptomatic SARS-CoV-2 infected people, and thus be able to carry out events related to leisure in a safe environment. The aim of this study is to make a mass screening of asymptomatic infection of an (i) experimental group (public attending a massive mass musical show) and (ii) a control group (they will not enter the event) prior to entering to the event. Randomization 1: 1 by random blocks of the participants with a negative antigen test in the experimental group (attending the event) and the control group (they will not enter the event). Control with a new Polymerase Chain Reaction (PCR) test 8 days after the event (D8) in the participants of both randomized groups Control of the appearance of symptoms through a questionnaire 10 days after the event (D10), in the participants of both groups with a negative result on day 8. Validation of a rapid antigen detection test by comparison with the PCR technique. The indoor activity will include an array of measures designed to reducing the contagion risk, including: mandatory wearing a mask during the event, restricted outdoor areas of bar and smoking, enhanced ventilation of the whole indoor area, and avoiding queues. All subjects will have downloaded an app in their smart phones to help contact and place tracing during the event, to trace potential transmissions. This app will remain active for 8 days, until the last virologic control. The inclusion criteria will allow only subjects with an age <60 years, without comorbidities, and who do not live with old adults in their homes, to further reduce the risk of potential complications and transmission to at risk individuals.
Background: Up-to-date, there is no recognized effective treatment or vaccine for the treatment of coronavirus disease (COVID-19) that emphasize urgency around distinctive effective therapies. This study aims to evaluate the anti-parasitic medication efficacy "Ivermectin" plus standard care (Azithromycin, Paracetamol, vitamin C, Zinc, Lactoferrin, Acetylcystein, prophylactic or therapeutic anticoagulation if D-dimer > 1000 and/or steroids) in the treatment of mild/moderate and severely ill cases with COVID 19 infection versus Hydroxychloroquine plus standard care, as well as Ivermectin prophylaxis of health care and/ or household contacts. Subject and methods: 600 subjects; 400 symptomatic confirmed COVID-19 patients and 200 health care and household contacts distributed over 6 groups; Group I: 100 patients with Mild/Moderate COVID-19 infection received a 4-days course of Ivermectin plus standard care; Group II: 100 patients with mild/moderate COVID-19 infection received hydroxychlorquine plus standard care; Group III: 100 patients with severe COVID-19 infection received Ivermectin plus standard of care; Group IV: 100 patients with Severe COVID-19 infection received hydroxychlorquine plus standard care. Routine laboratory investigations and real time- polymerase chain reaction (rt-PCR) were reported before and after initiation of treatment. Group V stick to personal protective equipment (PPE) plus Ivermectin, and Group VI stick to PPE only and both groups were followed for two weeks.
Estimated number of participants: 342 participants with COVID-19 Design: Phase III, single-center, randomized, double-blind, parallel, placebo-controlled clinical study. In December 2021, there was a drop in the number of hospitalizations and the cases of COPD, tuberculosis and HIV associated with COVID-19, which are outside the inclusion criteria of this study. After the initial data of the study, there was a discussion with Anvisa and the size of the sample calculation was revised by amendment 4 (180 participants), and the methodology of statistical analysis for a new sample calculation was "a formula for sample calculation for superiority studies using proportions, according to the book do Chow et al (Chow, S.-C., Shao, J., Wang, H., &Lokhnygina, Y. Eds. 2017. Sample Size Calculations in Clinical Research: Third Edition, Chapman and Hall/CRC). Thus, Anvisa concluded that the adjustments are in accordance with the agency's guidelines, approving E4, which was later also approved by the Ethics Committee.
COVID-19 pneumonia can cause severe acute hypoxemic respiratory failure. The usefulness of noninvasive respiratory support (NIRS), by means of nasal high-flow oxygen (NHFO), continuous positive airway pressure (CPAP), or noninvasive ventilation (NIV), established outside the intensive care unit, is unknown. The aim of this multicenter, retrospective, longitudinal study is to compare the effectiveness of these treatments to prevent death or endotracheal intubation at day 28, and what factors, related to the disease or to the characteristics of the treatment itself, can condition its success or failure.
Persons infected with Severe Acute Respiratory Syndrome (SARS) SARS-CoV-2 vary in severity from being asymptomatic to having fever, cough, sore throat, general weakness and fatigue and muscular pain and in the most severe cases, severe pneumonia, acute respiratory distress syndrome and sepsis potentially leading to death. Predictive markers of clinical worsening after admission are lacking. COVID-19 immunopathogenesis and relevant therapeutic strategies are still under investigation. Although viral shedding peaks during the first week of symptoms, reports show that clinical deterioration often coincides with the development of host antiviral immune responses. The inflammatory response to SARS-CoV-2 infection may underpin COVID-19 pathogenesis leading to aberrant and excessive immune responses that may enter the pulmonary circulation in large numbers and play an immune damaging role causing lung functional disability resulting in clinical worsening. Therapeutic strategies using corticosteroids or biotherapies targeting IL-6 may be valuable in some patients. Based on a better understanding of COVID-19 immunopathogenesis, the identification of predictive biomarkers early in the disease process would be of outstanding interest to tailor prompt therapeutic interventions. On these bases, the present project aims to unravel, using innovative integrated multimodal immunological approaches, immunologic predictive markers by finely characterizing from their admission innate and adaptive immune responses in two well described cohorts of COVID-19 patients that are being collected in Toulouse (COVID-BioToul) and Bordeaux (COLCOV-19 BX).Those two biological cohorts are connected with two clinical cohorts in Toulouse and Bordeaux in order to have a very well defined population of COVID-19 patients and their clinical outcome. In both cohorts, investigators harvest and cryopreserve biological samples, including plasma and peripheral blood mononuclear cells (PBMCs), on admission and longitudinally from patients evolving or not toward severe forms of the disease in Bordeaux and Toulouse University Hospitals and will allow to investigate primary and secondary objectives. Moreover in the two centers, there are also two clinical outpatients cohorts of healthcare workers attending dedicated clinics in the frame of their surveillance medical program, which constitute groups of patients with benign forms of COVID-19.
Non-invasive ventilation can allow to avoid intubation and improve outcomes in moderate-to-severe COVID-19-associated acute respiratory distress-syndrome (ARDS). Data on NIV parameters adjustment based on expanded respiratory and gas exchange monitoring in COVID-19 associated ARDS is limited. Appropriate adjustment of the inspiratory positive airway pressure (IPAP) set as a point of the balance between minimal work of breathing (minimum point of W.Patrick scale for assessment of the accessory respiratory muscles and minimum diaphragm thickening fraction) and minimum tidal volume, and respiratory rate can decrease NIV failure in moderate-to-severe COVID-ARDS. The objective of the study is to evaluate the ability of non-invasive ventilation guided with expanded respiratory monitoring to decrease the intubation rate in in moderate-to-severe COVID-ARDS.
COVID-19 is associated with a cytokine storm that leads to respiratory distress, multiorgan failure and elevated mortality. Oral Colchicine exhibits high anti-inflammatory capacity attributed to the inhibition of microtubules polymerization, inflammasome and production of IL-1β and IL-6, which could prevent the inflammatory storm in COVID-19 patients at risk. The investigators present a randomized, controlled, open-labeled, and pragmatic clinical trial to study the treatment effect of Colchicine in COVID-19 patients requiring hospitalization, but no intensive care yet. Colchicine will be started within the first 48 hours and continue for 14 days using a descending dose. The benefits will be studied in terms of clinical evolution (WHO 7-point scale) and IL-6 levels, as well as other clinical and biochemical secondary end-points. In the case of positive results, the clinical impact would be relevant given that this oral medication is affordable and widely accessible which would help to prevent the inflammatory complications associated with COVID-19.
Prospective samples will be collected to evaluate the agreement between a EUA RT-PCR test as the comparator method against the Nanomix eLab® system.
This is a prospective comparative cohort trial taking place during the first year of the Coronavirus-19 (COVID-19) pandemic in Spain. Chiropractic patients throughout Spain were invited to participate independently of the care received, including patients who had stopped visiting their chiropractors since the pandemic hit. The main exposure variable is the access to chiropractic care services, and the degree of this exposure during the months following initial lockdown phase in Spain. Participants will fill an online questionnaire with self-reported outcome-measures.
Multicentre, retrospective, observational study to describe the course of SARS-CoV-2 disease in patients treated or not with IMUNO TF ® and a combination of nutraceuticals and who have tested positive in a COVID-19 diagnostic test based on the duration of symptoms.
