Filter by:In this trial patients will be treated with either a combination of therapies to treat COVID-19 or a placebo. Treatment will last 10 days, and patients will be followed for 6 months.
A total of 900 subjects are planned to be randomly divided into 2 doses of low-dose experimental vaccine group, 2 doses of high-dose experimental vaccine group, 2 doses of placebo group, 3 doses of low-dose experimental vaccine group, 3 doses of high-dose experimental vaccine group and 3 doses of placebo group, the sample size of each group was 150 cases.
A prospective and retrospective cohort study. The objective will to determine the frequency of COVID-19 in pregnant and postpartum women hospitalized with flu syndrome, to evaluate clinical and laboratory predictors of COVID-19 progression and to determine the factors associated with adverse maternal and perinatal outcomes in healthcare centers in two states of Northeast Brazil.The study will be conducted including pregnant and postpartum women with clinical or laboratorial diagnosis of COVID-19, admitted in six healthcare centers in the Northeast of Brazil. All pregnant and postpartum women with clinical and/or diagnosis of COVID-19, attended in prenatal care, in emergency (maternity triage), high-risk pregnancy ward, obstetric intensive care unit and rooming-in ward will be included. The data will be collected in specific forms. The exams will be carried out by trained professionals within each institution.
In Mexico the total number of confirmed cases of COVID-19 is 232, 000 and 28,510 deaths. Health workers are at high risk of COVID-19 infection. Their absence from work dramatically limits the ability to contain the disease. There is currently no vaccine to prevent the disease. Since the introduction to the vaccination schedule of the Bacillus Calmette-Guerin (BCG) live attenuated vaccine directed towards tuberculosis prevention, a decrease in infant mortality has been reported, not related only to tuberculosis. BCG vaccine has been hypothesized to have a non-specific role towards other unrelated pathogens such as viruses that cause airway disease, with reduced morbidity and mortality. In murine as well as in human models it has been shown to decrease the incidence of acute respiratory influenza infections. Likewise, in countries with a high endemicity for tuberculosis, the BCG vaccine reduces the incidence of respiratory infections by up to 80% . In healthy subjects, the BCG vaccine increases the production of proinflammatory cytokines in monocytes. Likewise, it increases the epigenetic response, causing an increase in the transcription of genes important in the antimicrobial response, as well as an improvement in cellular function. This is the first national clinical trial to evaluate prospectively the effect that the BCG vaccine offers towards the prevention and reduction of severity in cases of COVID-19.
The vast majority of individuals with Covid19 have mild illness that can be managed in the outpatient setting. A small but significant number of these people will deteriorate and require hospitalization. Symptoms are a poor - and possibly late - indicator for deterioration. While people who have died, and/or been cared for in the ICU or hospital have been well characterized, there remains a dearth of information about the clinical course of people in the outpatient setting. Most notably, it is not known when to escalate to hospital care. The consequence of non-escalation when needed is significant patient morbidity and mortality, of escalation when not needed is unnecessarily overwhelmed hospitals. Technologies for clinical management and early diagnostics for severe Covid19 infection will address this challenge. The research goal of this study is to use real-time remote patient monitoring to detect which patients with Covid19 are at risk of deterioration to bring to hospital, while at the same ensuring the worried will receive reassurance so they stay at home. The clinical goal is to help clinicians provide excellent care using ubiquitous mobile phones.
In this trial, a total of 50 subjects were recruited; the test vaccines were divided into 3 groups, low-dose vaccine groups, high-dose vaccine groups, and placebo groups. The first-stage randomized participants in the low-dose group (20 cases) and the placebo group (5 cases) were evaluated for 7 days. After the 7-day safety data was evaluated and agreed by the DSMB, the second-stage study was conducted. Into the high-dose group (20 cases) and placebo group (5 cases) subjects; follow-up to 30 days, after the safety assessment by the investigator and consent, then inoculate the second dose. Observation was performed for 1.0 hour after the second dose. The researchers conducted a safety evaluation and agreed to follow-up after discharge.
A Phase I/II, double-blinded, placebo-controlled, individually randomized trial to assess safety, immunogenicity and efficacy of the candidate Coronavirus disease (COVID-19) vaccine ChAdOx1 nCoV-19 in adults aged 18-65 years living with and without HIV in South Africa. The vaccine or placebo will be administered via an intramuscular injection into the deltoid muscle of the non-dominant arm.
The study aims to identify environmental factors and genetic (gene mutation and gene expression) changes, which influencing the course of the disease the new type of coronavirus infection COVID-19 in patients nationwide in a multicenter study. At first in the study will be performed 200 patients, selected for a homogeneous groups on the basis of the patient's anamnestic data, genetic testing. Following the interim analysis, based on the results, another 800 people are planned to involve.
Patients suffering from pneumonia due to SARS-CoV-2 infection, after admission to the Intensive Care Unit (ICU), are susceptible to development of various functional sequelae, increased risk of chronic diseases, increased mortality rates and existence of relevant impacts on their quality of life in the months and years that follow the ICU admission. The present study aims to assess the determinants of health-related quality of life and patient-centered long-term outcomes among patients recovered from SARS-COV-2 pneumonia, after discharge from the ICU, its determinants and predictors, in Portugal. It is a multicenter prospective cohort study of adult patients admitted at the ICU due to proven or suspected SARS-CoV-2 infection, included 90 days after discharge from the ICU. The primary outcome is one-year health-related quality of life assessed by the EQ-5D-3L. The secondary outcomes are all-cause mortality, rehospitalizations, return to work or study, the degree of dependence and functional capacity, symptoms of anxiety, depression and post-traumatic stress, level of physical activity and cognitive, renal and respiratory functions after ICU discharge. Investigators will collect data by means of structured telephone interviews, at a 12 months follow up period.
A phase 2/3 study to determine the efficacy, safety and immunogenicity of the candidate Coronavirus Disease (COVID-19) vaccine ChAdOx1 nCoV-19 in healthy UK volunteers.
