Filter by:Coronavirus (COVID-19) is a pandemic-like disease caused by a new coronavirus called Severe Acute Respiratory Syndrome Coronavirus 2 (SARSCoV-2) isolated in China in 2019. Clinical manifestations vary widely from one individual to another, from asymptomatic carrier to a febrile cough that can rapidly lead to acute respiratory distress syndrome. Since the beginning of the COVID-19 epidemic, screening by chest X-ray (RT) and polymerase chain reaction (PCR) SARS-CoV-2 conducted by the Cornwall Hospital Union laboratory has shown that among symptomatic patients and hospital staff suspected of being COVID-19, only 7.8% were attributable to COVID-19. Two nosocomial clusters were also identified, in the emergency department (10 carers) and in the cardiology department (6 carers and one patient). However, direct diagnosis by RT-PCR has sensitivity limits and can lead to false negative results when the subject is indeed suffering from COVID-19. This lack of sensitivity is inherent to the technique on the one hand, but also to the quality of the sample and the kinetics of the infection. Indeed, the virological window during which the virus is present in the respiratory mucous membranes sampled seems relatively narrow, hence a progressive negativation of the respiratory samples as the disease progresses. Moreover, clinical symptoms vary from one individual to another, and it is now recognized that some infected persons are asymptomatic but carry the virus. Thus, the use of a second diagnostic technique is a necessity, and serology could be a relevant diagnostic support. In the literature, several publications report the performance of COVID-19 serology in clusters of cases or cohorts of subjects. The serological techniques employed are variable (target epitopes in particular) and frequently homemade. Serology is mainly studied in comparison or association with RT-PCR in order to highlight the increased performance of COVID-19 diagnosis when the two techniques are combined. Correlation with chest CT imaging data is also encountered. Numerous serological tests are therefore being tested to determine retrospectively whether the individual has been exposed to the virus by looking for specific antibodies to the virus. The supreme health authority has drawn up specifications dated 16 April 2020, defining the methods for evaluating the performance of serological tests detecting antibodies directed against SARSCoV-2 in order to provide a framework for these practices. Several clinical studies are also underway, in particular to assess the kinetics of the appearance of the antibodies, whether these specific antibodies would be protective and whether their appearance would coincide with a cessation of contagiousness. Thus, the main objective of this study is to evaluate the diagnostic performance of the COVID-19 immunoglobulin (IgG) Dia-Pro serological test, in view of its deployment at the Cornish Hospital Union Laboratory. Subsequently, given the low prevalence of COVID-19 in Brittany and the risk of a second epidemic wave when the confinement is lifted, the evaluation of the seroprevalence of the staff of the Cornish Hospital Union is necessary in order to assess the attack rate of COVID-19 within the establishment and particularly within departments where nosocomial clusters have been reported; and to prevent the impact of deconfinement. Indeed, knowledge of the proportion of immunized personnel and its distribution according to services will make it possible to establish internal recommendations and to effectively manage personal protective equipment inventories, in conjunction with the deconfinement strategy that will be implemented by the government. The goal is to protect hospital staff from overexposure to the virus;
This a double-blind, randomized, placebo-controlled clinical trial to determine if primary prophylaxis with hydroxychloroquine in healthcare workers reduces symptomatic COVID-19 infection. Healthcare workers will be randomized at a 1:1 allocation between intervention and placebo arms and followed for 12 weeks. This study will enroll up to 1,700 participates in Lafayette, Louisiana. The primary outcome will number of symptomatic COVID-19 infections. Secondary endpoints included number of days healthcare workers are absent from work and rate of severe infection.
The most prevalent complication of COVID-19 infection is respiratory failure from severe acute respiratory syndrome (SARS), the leading cause of mortality. There is increasing indication that the decompensation in severe COVD-19 infection may be due to a cytokine storm syndrome. This hyperinflammatory syndrome results in a fulminant and fatal hypercytokinemia and multiorgan failure. Approximately 15% of patients with COVID-19 infection are hospitalized and 20-30% of these hospitalized patients require ICU care and/or mechanical ventilation. Overall mortality in hospitalized patients is approximately 20-25%. There is significant interest in therapies that can be given upstream to reduce the rate of mechanical ventilation and thus mortality. We hypothesize that treatment with colchicine in COVID-19 moderate-severe patients may decrease the risk of progression into ARDS requiring increased oxygen requirements, mechanical ventilation, and mortality.

LIINC is a study of volunteers who were previously infected with SARS-CoV-2 (also known as novel coronavirus or COVID-19) who have recovered from acute infection. The study is designed to provide a specimen bank of samples with carefully characterized clinical data. LIINC specimens will be used to examine multiple questions involving the virologic, immunologic, and host factors involved in COVID-19, with a focus on understanding variability in the long-term immune response between individuals.
It is an observational, cohort, retrospective, monocentric, non-profit study. The primary objective is to evaluate the efficacy and safety of ruxolitinib in acute respiratory distress syndrome in patients with SARS-CoV-2 COVID-19 with rapid deterioration of respiratory parameters in the last 12 hours.
This is a multicenter; double blind randomized controlled study investigating the role of remote intercessory multi-denominational prayer on clinical outcomes in COVID-19 + patients in the intensive care unit. All patients enrolled will be randomized to use of prayer vs. no prayer in a 1:1 ratio. Each patient randomized to the prayer arm will receive a "universal" prayer offered by 5 religious denominations (Christianity, Hinduism, Islam, Judaism and Buddhism) in addition to standard of care. Whereas the patients randomized to the control arm will receive standard of care outlined by their medical teams. During ICU stay, patients will have serial assessment of multi-organ function and APACHE-II/SOFA scores serial evaluation performed on a daily basis until discharge. Data assessed include those listed below.
Background: There are no proven therapies for COVID-19 infection. COVID-19 infects the respiratory epithelium of the lower airways, causing widespread damage via cytopathic effects, resulting in severe inflammation and Pneumonitis. High local and circulating levels of cytokines, or cytokine storm, can lead to capillary leak syndrome, progressive lung injury, respiratory failure and acute respiratory distress syndrome (ARDS). Methods: This is a pilot randomized, controlled, uni-center study testing safety and efficacy of cytokine filtration on patients with severe ARDS. Eligible patients will be randomized to 72 hours filtration or no filtration on top of the standard treatment for ARDS. Indications for randomization are patients with moderate or severe ARDS with need of ventilation support (either invasive or non-invasive), with inflammatory markers. The primary outcome will be days on mechanical ventilation (MV) support. Secondary outcomes are 30-day mortality, ICU days, need for extracorporeal membrane oxygenation (ECMO) support, duration of renal replacement therapy (RRT) and catecholamine therapies, hospital length of stay, multi-organ failure. All analysis will be done according to the intention to treat principle.
The Severe Acute Respiratory Syndrome CoronaVirus 2 (SARS-CoV2) has been identified in Wuhan, China, which causes severe pulmonary complications and flu syndrome, which has spread rapidly to all continents. Approximately 25% of hospitalized patients require treatment in intensive care units and 10% require mechanical ventilation. The diagnosis is made by the molecular polymerase chain reaction test. However, diagnostic tests are limited. The clinical care of the patient with COVID-19 is similar to that of patients with severe infectious respiratory complications, consisting of support and oxygen supplementation. Several medications have been tested as remdesivir, a pro-drug nucleoside, which acts by inhibiting viral RNA transcription, although a recently published study has shown no benefit. China recently approved the use of favipiravir, an antiviral used for influenza, as an experimental therapy for COVID-19. Hydroxychloroquine is a drug with great potential treatment, as it can inhibit the pH-dependent steps of replication of various viruses, with a potent effect on SARS-CoV infection and spread. In this way, the present study will evaluate the safety and efficacy of the hydroxychloroquine in patients with symptomatic SARS-Cov2.
