Filter by:To evaluate the performance of the FDA EUA authorized Lucira COVID-19 All-In-One Test Kit for the qualitative detection of SARS-CoV-2 virus in nasal swab samples as compared to a known high sensitivity EUA RT-PCR among asymptomatic individuals. The comparator assay for this study is the Hologic Panther Fusion SARS-CoV-2 RT-PCR Assay.
Rumors circulate widely during public health crises and have deleterious consequences. In this study, we seek to document the base rates of migrant workers' rumor exposure and identify predictors of rumor hearing, sharing and belief.
This is a multicenter open-label randomized study for the early treatment of pneumonia due to SARS-COV2 with transfusion of convalescent plasma. Patients with pneumonia due to SARS-CoV-2 will be randomized to receive or not convalescent plasma collected by recovered patients with previous diagnosis of COVID19
The investigators hypothese that lung involvement due to COVID-19 may cause structural changes in the lung in the long term. In this study the effects of structural changes in the lung on pulmonary function tests, exercise capacity and quality of life will be examined.
This study will evaluate the associations between vascular parameters and clinical outcomes in patients hospitalized with COVID-19. The vascular function and structure of individuals with COVID-19 admitted to the General Hospital of the University of Sao Paulo will be assessed in the first 72 hours of hospitalization. Then, participants will be followed up until hospital discharge/death. Logistical regressions will be run to evaluate if vascular function/structure can predict ICU admissions, intubation, thrombosis or death.
This clinical trial aims to determine if fluvoxamine, a selective serotonin reuptake inhibitor with high affinity for the sigma-1 receptor, can be used in mild to moderate COVID-19 to prevent the progression to severe COVID-19. Fluvoxamine is an anti-depressant drug approved by the FDA for the treatment of obsessive-compulsive disorder and has a potential for immune modulation as a sigma-1 receptor agonist. The investigational use of fluvoxamine for the treatment of COVID-19 is approved by the South Korean Ministry of Food and Drug Safety. This study is performed fully-remotely at COVID-19 community treatment centers, temporary facilities in Seoul, Korea, to accommodate and monitor asymptomatic to moderately symptomatic case-patients who do not require hospital admission.
Maraviroc (MVC) is a drug, very well tolerated, it has been seen that MVC has properties of modulating the immune system, exerting an anti-inflammatory effect in different diseases. In COVID-19, very high levels of inflammation occur that cause organs and systems to be damaged. MVC could reduce this inflammation achieving a better prognosis of COVID-19.
Although clinical trials for approved COVID-19 vaccines demonstrated efficacy of the vaccine in preventing symptomatic infection, many questions about vaccine effectiveness, such as the effectiveness of COVID-19 vaccine in preventing asymptomatic infection, a surrogate for transmission, and duration of protection, can only be evaluated in real-world trials. The objective of the study is to evaluate COVID-19 vaccine effectiveness (Pfizer vaccine, and, if available, Moderna vaccine) in preventing infection in healthcare personnel in Israel. HCP who are Clalit members and working in Soroka, Beilinson, Meir, Haemek, Kaplan and Schneider hospitals, 18 years or older, and eligible to get COVID-19 vaccine according to Ministry of Health guidelines, will be recruited, regardless of their intention to get the COVID-19 vaccine. A baseline serology sample and respiratory sample will be collected. Participants will be asked to provide a respiratory sample weekly for 3 months, and then monthly for the remainder of the study. Participants will also have blood drawn at 1 month, 3 months, 6 months, 9 months and 12 months. Respiratory samples will be tested for SARS-CoV-2 by RT-PCR; serology will be tested for SARS-CoV-2 antibodies. The study will last for 12 months. For each participant, data will be extracted from the Electronic Medical Record for the period of the study and retrospectively from 2010.
The investigators will study nasopharunx microbiota composition, RNA sequences and in vitro cytokines production by peripheral blood cells of COVID-19 patients (both mild-moderate and severe cases) (comparing with convalescent patients and healthy controls).
At present, the offer of tests for the serological diagnosis of CoVID-19 (detection of IgG, IgM or IgA antibodies against CoV-2 SARS) is plethoric and is based on the use of a very large number of rapid diagnostic unit tests, a few dedicated high throughput automated systems or reagents on existing open systems. The offer will continue to expand in the coming months. In order to meet the objectives mentioned by the Prime Minister, and confirmed in the HAS report of April 16, 2020 and in the opinion n°6 of the COVID-19 scientific council concerning the potential use of these serological tests at the end of the COVID-19 epidemic, the Virology laboratory wishes to validate the sensitivity and specificity of the tests it intends to use.
