Filter by:COVID-19 may cause another world-wide epidemic. This study is divided into 2 arms: (1) Prospective longitudinal observational study involving patients with laboratory-confirmed COVID-19 and (2) Retrospective study on patients with laboratory-confirmed COVID-19. Arm 1: We will collect EDTA blood, stool samples, rectal swab, urine, saliva, and specimens from upper respiratory tract (nasopharyngeal aspirate or flocked swab), and lower respiratory tract (sputum or tracheal aspirate) on daily, alternate day, or weekly basis as appropriate. Arm 2: The remainder of specimens that were submitted for laboratory investigation as part of clinical management will be retrieved. Those specimens will only be used after all clinically indicated testing and confirmation procedures have been completed. Assistance from the Public Health Laboratory Service, Department of Health, will be invited to retrieve samples as well as participate in this study. Patients hospitalized for pneumonia in medical wards and ICU at the Prince of Wales Hospital tested negative for COVID-19 will be recruited as controls. Understanding the clinical, virological, microbiological and immunological profiles of this infection is urgently needed to facilitate its management and control.
Coronavirus disease 2019 (COVID-19) is an emerging infectious disease that was first reported in Wuhan, China, and had subsequently spread worldwide. Twenty-nine percent of COVID-19 patients may develop ARDS. Based on the potential beneficial mechanisms of HFNC and PP, whether early use of prone positioning combined with HFNC can avoid the need for intubation in COVID-19 induced moderate to severe ARDS patients needs to be further investigated.
A new human coronavirus responsible for pneumonia, SARS-CoV-2, emerged in China in December 2019 and has spread rapidly. COVID-19, the disease caused by this virus, has a very polymorphous clinical presentation, which ranges from upper respiratory tract infections to acute respiratory distress syndrome. It may appear serious straightaway or may evolve in two stages, with a worsening 7 to 10 days after the first clinical signs, potentially linked to a cytokine storm and accompanied by a high risk of thrombosis. The global mortality rate of COVID-19 is between 3% and 4%, with severe forms being more frequent among older patients. Management is symptomatic as no antiviral treatment has demonstrated any clinical benefit in this condition. Hydroxychloroquine is a derivative of chloroquine commonly used in some autoimmune diseases, such as systemic lupus erythematosus. It is active in vitro in cellular models of infection by many viruses such as HIV, hepatitis C or SARS-CoV. However, its interest in viral infections in humans has not been demonstrated. Very recently, a preliminary uncontrolled study evaluated the effect of hydroxychloroquine on viral shedding in subjects with COVID-19. Among 20 patients treated with hydroxychloroquine at a dose of 600 mg per day, the percentage of patients with detectable SARS-CoV-2 RNA in the nasopharynx decreased from 100% at inclusion (start of treatment) to 43% six days later. In comparison, 15 of 16 untreated patients had a positive RT-PCR six days after inclusion. Furthermore, hydroxychloroquine has immunomodulating and anti-inflammatory properties, which could theoretically prevent or limit secondary worsening. The research hypothesis is that treatment with hydroxychloroquine improves prognosis and reduces the risk of death or use for invasive ventilation in patients with COVID-19.
Researchers are trying to assess the treatment potential and safety of anti-SARS-CoV-2 convalescent plasma in patients with acute respiratory symptoms with confirmed COVID-19.
CAPACITY (www.capacity-covid.eu) is a registry of patients with COVID-19 across Europe and has been established to answer questions on the role of cardiovascular disease in this pandemic. It is an extension of the Case Record Form (CRF) that was released by the ISARIC (International Severe Acute Respiratory and Emerging Infection Consortium) and WHO (World Health Organisation) in response to the emerging outbreak of COVID-19.
Study on adult patients positive to COVID-19 virus. After signing informed consent and undergoing screening assessments, eligible patients will record few times a day several pre-defined sentences to the Cordio App installed in a smartphone/tablet. The app will upload the vocal data to the sponsor's servers for analysis. The patient will record at hospital admittance (COVID-19 positive) until patient defined as COVID-19 negative and free of relevant clinical symptoms.
This study will assess the prevalence and incidence of COVID-19 infection in patients with chronic plaque psoriasis on immunosuppressant therapy.
COVID-19 (Coronavirus Disease-2019) is a life-threatening infectious disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that appeared in December 2019 in the Wuhan district. COVID-19 has since affected more than 150 countries across the world and especially France. The first epidemiological data, mostly from Chinese studies, indicate that diabetes is one of the most common comorbidities, with high blood pressure, in patients with COVID-19. Moreover, the presence of diabetes at admission would be a risk factor for both ICU hospitalization and death. Nevertheless, specific data on people with diabetes and COVID-19 are fragmentary, justifying the achievement of a dedicated prospective observational study. The French nationwide CORONADO study aims to specifically describe the phenotypic characteristics of patients with diabetes admitted to hospital with COVID-19 infection. Particular attention will be devoted to glycemic control at admission (i.e. the level of HbA1c), the diabetic complications, as well as anti-diabetic and antihypertensive therapies. This study will provide answers to caregivers and patients with diabetes regarding the risk factors related to diabetes for COVID-19 prognosis. This pilot study will be used for the development of new studies and for the establishment of recommendations for the cost of care in patients with diabetes and COVID-19.
A phase I/II single-blinded, randomised, multi-centre study to determine efficacy, safety and immunogenicity of the candidate Coronavirus Disease (COVID-19) vaccine ChAdOx1 nCoV-19 in UK healthy adult volunteers aged 18-55 years. The vaccine will be administered intramuscularly (IM) into the deltoid region of the arm
In December 2019 in the city of Wuhan in China, a series of patients with unclear pneumonia was noticed, some of whom have died of it. In virological analyses of samples from the patients' deep respiratory tract, a novel coronavirus was isolated (SARS-CoV-2). The disease spread rapidly in the city of Wuhan at the beginning of 2020 and soon beyond in China and, in the coming weeks, around the world. Initial studies described numerous severe courses, particularly those associated with increased patient age and previous cardiovascular, metabolic and respiratory diseases. A small number of the particularly severely ill patients required not only highly invasive ventilation therapy but also extracorporeal membrane oxygenation (vv-ECMO) to supply the patient's blood with sufficient oxygen. Even under maximum intensive care treatment, a very high mortality rate of approximately 80-100% was observed in this patient group. In addition, high levels of interleukin-6 (IL-6) could be detected in the blood of these severely ill patients, which in turn were associated with poor outcome. From experience in the therapy of severely ill patients with severe infections and respiratory failure, we know that treatment with a CytoSorb® adsorber can lead to a reduction of the circulating pro- and anti-inflammatory cytokines and thus improve the course of the disease and the outcome of the patients. Our primary goal is to investigate the efficacy of treatment with a CytoSorb® adsorber in patients with severe COVID-19 disease requiring venous ECMO over 72 hours after initiation of ECMO. The primary endpoint is the reduction of plasma interleukin-6 levels 72 hours after initiation of ECMO support. As secondary endpoints we investigate 30-day survival, vasopressor and volume requirements, lactate in terms of lactate and platelet function. As safety variables, we further investigate the levels of the applied antibiotics (usually ampicillin and sulbactam).
