In this study we cross-reference several nationwide high-quality Swedish registers in order to study risk factors for severe Covid-19 outcomes.
The question of the immune response of the population, particularly of professional populations in contact with vulnerable populations (such as those with chronic conditions such as cancer), is an important issue. Knowing the evolution of this response over time in this population can help answer outstanding questions. The PRO-SERO-COV study is a seroprevalence study of caregivers working in the hospital sector with a follow-up at 3 months and 12 months. The objective is to evaluate and monitor at 3 and 12 months the serological immune status to an infection by the SARS-CoV-2 virus in active volunteer professionals working at the Institut Bergonié with different types of exposure: healthcare professionals and professionals in other services.
Currently, no effective treatments are available for the COVID-19. Scientists and Researchers are working on many aspects of treatment options for the development of vaccination and medication to combat this life-threatening problem. Convalescent plasma from recovered COVID-19 patients contains antibodies against COVID-19 which may be beneficial to severely sick COVID-19 patients. Investigator have recently concluded a pilot phase II open-label RCT on the efficacy of convalescent plasma in severe COVID 19 patients in which encouraging results were seen. Investigator plan to further study the efficacy and safety of convalescent plasma in COVID-19 severely sick patients through an RCT. Investigator will collect up to 500 ml Convalescent Plasma from the COVID-19 recovered persons after 14 days of clinical recovery with two consecutive SARS CoV-2 negative tests by PCR at least 24 hours apart. This plasma will be tested and frozen and stored. On requisition it will be thawed and sent to the treating center. Two doses of 250 ml convalescent plasma each will be transfused on two consecutive days to patients who fit the eligibility criteria (Severely sick COVID-19 patients) and are randomized to the convalescent plasma group along with the standard of care and the other group will receive standard of care alone. Data will be collected to study the benefits and adverse events related to convalescent plasma transfusion.
Observational, point of prevalence study determining the presence of anti-SARS-CoV-2 antibody
Estimation of the prevalence and contagiousness of undocumented novel coronavirus infections is critical for understanding the overall prevalence and pandemic potential of this disease. It is estimated that 86% of all infections were undocumented [95% credible interval (CI): 82-90%] before the 23 January 2020 travel restrictions. The transmission rate of undocumented infections per person was 55% the transmission rate of documented infections (95% CI: 46-62%), yet, because of their greater numbers, undocumented infections were the source of 79% of the documented cases. Ivermectin + Carrageenan, taking advantage of their virucidal effects, are aimed at reducing the contagion.
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has affected the global population with significant morbidity and mortality. One of the main concerns is the management of the patients since there is no specific treatment for this condition. Therefore, in SARS-CoV-2 patients the compassionate use of off-label therapies has been initiated; such as the use of plasma from convalescent patients. This treatment has been used in other pandemics like SARS-CoV-1, H5N1, H1N1, Ebola, among others. This study is a phase II/III randomized clinical trial to assess the effectiveness and safety of convalescent plasma administration in patients with high-risk SARS-CoV-2.
To evaluate the efficacy and safety of azvudine in treatment of COVID-19
Observational and prospective study with one year of follow-up of the cohort of workers of the CSdM, including workers of subcontracted companies working in the Hospital of Mataró (2,300 workers approximately) and with controls at baseline and at 3, 6, 9 and 12 months. All CSdM workers will be invited to participate by e-mail and by announcements in the corporate website. A space will be set up on the corporate intranet where workers will be informed about the study, will be able to give their informed consent and will be able to answer an electronic questionnaire regarding socio-demographic, clinical and labour personal characteristics. Once the questionnaire answered, participants will be authorized to schedule a blood extraction. Prevalence of antibodies against SARS-CoV-2 will be analyzed (IgA, IgM, IgG). PCR will be also performed for IgM and IgA positive subjects.
The purpose of this study is to evaluate safety, tolerability, and pharmacodynamics of MK-5475 after administration of multiple doses to participants with COVID-19 pneumonia. The primary hypothesis is that MK-5475 when administered to participants with COVID-19 pneumonia and hypoxemia improves arterial oxygenation as measured by the ratio of blood oxygen saturation to fraction of inspired oxygen (SpO2/FiO2 ratio) compared to placebo.
