Active clinical trials for "COVID-19"

This is an open-label uncontrolled study in which all participants will receive two doses of the inactivated adsorbed vaccine against COVID-19, and will be followed up for safety and immunogenicity analysis for 24 months.

Multicenter retrospective cohort study from June to August 2020 on hospitalized COVID-19 patients admitted to Al-Hakeem and Al-Amal hospital in Al-Najaf Governorate, Iraq, in order to evaluating the effectiveness of plasma therapy in hospitalized patients with COVID-19 and analyzing factors that affect therapeutic outcome, either related to patients or related to donors.

This is a stepped-wedge cluster randomized trial to assess effectiveness of Sinovac's Adsorbed COVID-19 (Inactivated) vaccine. Residents in the urban area of a municipality are eligible to participate. The city was divided in clusters and those cluster were grouped to determine the offer of vaccination in four steps. The vaccine will be offered to adults (18 years old and above) according to the location of their homes in a cluster. The vaccine schedule is two doses with four-weeks interval. Baseline samples to determine previous immunity will be collected before vaccination. Cases of COVID-19 reported in the city will be recorded according to the WHO clinical progression scale. Comparison of periods before and after vaccination and relation to immunization coverage will be considered for the assessment of effectiveness in the clusters and groups of clusters.

This is an observational study that will prospectively record and monitor responses and clinical outcomes of patients with cancer after covid-19 vaccination, including measurements of antibody titers in serum and also record potential factors that affect immunity, such as type and stage of cancer, type and time of systemic therapy in relation to covid-19 vaccination.

Azithromycin (AZ) is used in the pediatric group in COVID-19 diseas. It has been reported to cause prolongation in the QT interval in adult age group. The aim of this study is to evaluate the effect of AZ on ventricular repolarization in COVID-19 positive pediatric patients. METHOD The study was conducted prospectively in July-August 2020. COVID-19 pediatric patients who received AZ treatment were included in the study. ECG was obtained before treatment and on the 1st, 3rd and 5th days after the treatment. Measurements were made with Image J program®. QTmax, QTmin, Tp-emax, Tp-emin intervals were measured. QTcmax, QTcmin, Tp-ecmax, Tp-ecmin, QTcd, Tp-ecd, and QTc / Tp-ec ratios were calculated with Bazett formula.

With the rapid spread of COVID-19 (SARS-CoV-2) disease all over the world and the announcement of a pandemic, researches on many different drug approaches have begun and these researches continue today. Considering the absence of a specific treatment for the disease yet and the urgency of the situation, drugs previously licensed for the treatment of other diseases and thought to be effective in COVID-19 have started to be used. Ongoing studies are conducted on the effectiveness, possible side effects and safety of these drugs in COVID-19, but there is no clear information yet. It is thought that the anti-inflammatory and antioxidant properties of some vitamins and trace elements may be associated with positive results in COVID-19 patients, and the physiological roles of these vitamins and trace elements in COVID 19 have been demonstrated by studies. It is important to investigate the levels of free radicals known to be effective in the development of cardiovascular disease due to homocysteine and oxidative stress, which can provide information on determining the risk of cardiovascular complications in the COVID-19 pandemic. In addition, as the decrease in physical activity levels of individuals in the COVID-19 pandemic may cause possible secondary complications such as an increase in the risk of cardiovascular disease, determining the physical activity levels of individuals and encouraging them to physical activity is another important parameter to minimize the negative effects of the process. It is thought that investigating the effects of the treatment approaches used in COVID-19 on trace element, homocysteine, oxidative stress parameters and physical activity levels will provide useful information in determining the factors underlying better clinical results. This study was planned to be carried out between 6-31 January 2021 in order to compare the trace element, homocysteine, oxidative stress parameters and physical activity levels before and after treatment for COVID-19 disease in COVID-19 patients who applied to Izmir Bakircay University Cigli Training and Research Hospital (Cigli Regional Training Hospital) and hospitalized in the COVID-19 service. Research data will be obtained from blood samples taken from participants. In addition, data on physical activity levels will be collected through a questionnaire. After analyzing the data obtained from the research with appropriate statistical methods, the data will be evaluated.

The pathogenesis of COVID-19, which is caused by the coronavirus species, which has become a global health problem affecting the lives of billions of people worldwide and is a member of the Betacoronavirus genus, is not fully understood. Although its pathogenesis is thought to be multifactorial, it results in a systemic hyperinflammatory response and associated thromboembolic complications in severe cases. It is thought that some vitamins and nutrients may be beneficial for COVID-19 infected patients due to their anti-inflammatory and antioxidant properties. Vitamins such as A, B, C, D, E and folate; trace elements such as iron, zinc, magnesium, selenium and copper play important roles in supporting both innate and adaptive immune systems, and studies have shown that the trace elements investigated have important roles in COVID-19. For this reason, it is important to investigate the levels of trace elements. In addition, while the disease spreads all over the world, individuals are required to stay at home for a long time against the risk of contamination. Due to these isolation and limitations, physical activity levels decrease in individuals. As reductions in the level of physical activity may cause possible secondary symptoms, another parameter is to determine the physical activity level in order to prevent the potential harmful effects of these protective lifestyle regulations related to COVID-19 and to prevent the restrictions from causing physical inactivity. This study is planning to conduct between January and February 2021 in order to compare the trace element levels in blood samples and physical activity levels of patients with COVID-19 (SARS CoV-2) who applied to Izmir Bakircay University Cigli Training and Research Hospital (Cigli Regional Training Hospital) and hospitalized in the COVID-19 service. It was planned as a prospective, randomized controlled trial. Research data will be obtained from blood samples taken from participants. In addition, data on physical activity levels will be collected through a questionnaire. After analyzing the data obtained from the research with appropriate statistical methods, the data will be evaluated.

A retrospective cohort study will be conducted using a large administrative database of U.S. hospitals to understand the volume-outcome relationship among patients hospitalized with COVID-19.

Emerging evidence indicates that SARS-CoV-2, the etiologic agent of COVID-19, can cause neurological, neuropsychological and psychiatric complications. Given the global dimensions of the current pandemic, there is to consider the possible large-scale neurocognitive impact of COVID-19. Therefore, there is an urgent need for longitudinal studies to determine the acute and chronic effects that COVID-19 may have on the Central Nervous System. These putative effects include the possibility that the CNS serves as a reservoir for the virus, and that COVID-19 triggers CNS deleterious inflammatory cascades and neurodegenerative process. The public implications of these effects are very important in the long term.

During the COVID-19 pandemic, we noticed a rise in complicated appendicitis cases presenting to our medical center. We collected objective data on all patients admitted to the surgical department with appendicitis during February 2020 - March 2020 compared to the same 2 month period in 2019, to understand the pandemic's affect on the rate of complications of acute appendicitis.
