Active clinical trials for "COVID-19"

Coronavirus disease 2019 (COVID-19) which is caused by the virus SARS-CoV-2 has resulted in an ongoing global pandemic. It is unclear whether the relatively low number of reported cases of COVID-19 in people with CF (pwCF) is due to enhanced infection prevention practices or whether pwCF have protective genetic/immune factors. This study aims to prospectively assess the proportion of pwCF, including both adults and children with CF who have evidence of SARS-CoV-2 antibodies over a two-year period. This study will also examine whether pwCF who have antibodies for SARS-CoV-2 have a different clinical presentation and what impact this has on their CF disease. The proposed study will recruit pwCF from paediatric and adult CF centres in Europe. Serological testing to detect antibodies will be performed on blood samples taken at month 0, 6, 12, 18 and 24 with additional time-points if bloodwork is available via normal clinical care. Clinical data on, lung function, CF-related medical history, pulmonary exacerbations, antibiotic use, and microbiology and vaccination receipt, will be collected during routine clinical assessments. Associations will be examined between socio-demographic and clinical variables and serologic testing. The effects of SARS-CoV-2 infection on clinical outcomes and analyse end-points will be examined to explore any age-related or gender-based differences, as well as subgroup analysis of outcomes in lung-transplant recipients and pwCF receiving CFTR modulator therapies. As pwCF receive COVID-19 vaccination a comparison of the development and progression of anti-SARS-CoV-2 antibodies in pwCF following natural infection and vaccination SARS-CoV-2 over time will be performed.

Recent research evidence shows that levels of antibodies acquierd post vacunation against SARS-Cov-2 decrease over time as well as the efficacy to control the infection, additionally in a multicenter study carried out in 2020 were evidenced differences in the time it took to decrease the antibodies according to the type of vaccine, defined as mRNA or other types of vaccine. In this study , the variation of the SARS-Cov-2 antibody levels in patients from Valle de Aburrá will be correlated according to the COVID-19 vaccine received.

The purpose of this study is to test if visualizing the heart with cardiac MRI/echo will be important in the understanding cardiac function and prediction of cardiopulmonary symptoms, physical effort tolerance, and outcomes in COVID-19 survivors. If successful, the research will allow us to identify the causes of lasting cardiopulmonary symptoms and begin developing cardiac and lung directed therapies accordingly.

Background:The impact of the emergence of SARS-CoV-2 variants on the severity and clinical outcomes of COVID-19 is controversial. Whether virological characteristics including the mutational patterns of the different viral proteins (e.g., Spike, NSP proteins, ORF6) could be associated with a different immune response and subsequent severity of the disease is unknown. ln the next coming months, new variants carrying the same or new mutational patterns will continue to emerge. Monitoring their dynamics over time and their impact on disease severity is required for refining national and international disease control policies. Main objective: To unravel the relationships between specific viral mutations/mutational patterns and the clinical outcomes of COVID-19 in patients hospitalized in intensive care units (ICUs) for acute respiratory failure following severe SARS-CoV-2 infection. Design of the study Prospective multicentre observational cohort study Schedule for the study: Inclusion period: 24 months; Participation period: 28 days ; Total duration : 24 months + 28 days;

This is a cross-sectional research. The Protection Motivation Theory (PMT) was applied as theoretical framework to analyze correlation of prevention knowledge, prevention intentions and anxiety, and prevention behavior of COVID-19 and HIV risk feature and behavior and stigma of people living with HIV/AIDS (PLWHA), and HIV high-risk groups. Purposive and snowball sampling will be applied to recruit participant who visit hospital, HIV/AIDS related institutions, and social media platforms. The investigators expect that the outcome could reveal the relationship of cognition and attitude of COVID-19 to HIV prevention and treatment.

In response to the COVID-19 crisis, ISACS-TC has promoted a new registry of the existing and further centers of the same geographic areas to support clinical research to prevent, and treat the COVID-19 illness. These efforts are made possible by the generous contributions of clinical research volunteers in some of the countries participating to the prior acute coronary syndrome network.

Since December 2019, more and more cases of unexplained pneumonia appeared after exposure to the South China Seafood Market in Wuhan City, Hubei Province. Later, the disease were confirmed to be acute respiratory infectious diseases caused by the 2019 new coronavirus infection. Even though we have had great victories in the war against this pandemic, there is still a very large number of deaths early on. As research progresses, vaccines for this infectious disease are already being developed. There are currently two vaccines in widespread use worldwide: mRNA vaccines and inactivated vaccines. In China, inactivated vaccines are more commonly used. At present, some studies believe that mRNA vaccine does not affect the pregnancy rate and abortion rate of women, but the study sample size is small, and the conclusions are limited. The effects of inactivated vaccines on fertility are still in the blank. We now hope to conduct prospective studies, mainly to study the effect of inactivated vaccine injection on male semen, and whether it has an effect on the quality of embryos in IVF patients

There are a limited number of studies examining the difficulty of reaching treatment related to the pandemic process and the general effects of the process in patients with chronic low back and neck pain. However, no study has been found that compares the effects of individuals actively carrying and not carrying the Covid-19 virus. For this reason, the aim of the study is to examine the effects of the pandemic process on the cognitive level, pain catastrophization, physical activity level and quality of life in individuals with chronic low back and neck pain.

All surviving patients of the Michigan Medicine COVID-19 Cohort (M2C2, PI: Hayek) that were admitted to the University of Michigan for severe COVID-19 disease are eligible for this study. Investigators had prior approval from the Institutional Review Board (IRB) to collect the baseline blood and urine samples of these participants. Initial analysis on those samples are ongoing. In preliminary analysis of these patients a significantly higher risk for severe acute complications in patients with diabetes compared to those without diabetes was observed. The study will also enroll people following documented COVID-19 infection, regardless of whether or not they were hospitalized. The goal of the study is to understand what drives the increased risk of severe acute COVID-19 complications as well as to understand the long term sequelae of COVID-19 infection in patients with diabetes. The objectives of this study are to invite surviving M2C2 participants as well as others who have survived COVID-19 infection for an in-person visit, to measure biomarkers of inflammation and kidney, nerves, heart and blood vessels damage. participants will also be comprehensively phenotyped for diabetic complications outcomes, diabetes kidney disease, diabetes neuropathy and cardiovascular disease. Participants will be asked to fill out questionnaires to assess psychosocial metrics. The rationale is that correlating markers of acute hyperinflammation (cytokine storm syndrome) at admission in diabetes patients can inform vigilance and care for long term complications in survivors. Completing these studies will generate evidence-based guidelines for mitigating sequelae in diabetes COVID-19 survivors and identify critical psychosocial factors to mitigate psychological harm.

A randomized, double-blind, placebo-controlled phase II exploratory clinical trial to evaluate the efficacy and safety of Human COVID-19 immunoglobulin (pH4) for intravenous injection (COVID-HIG) in the treatment of patients with COVID-19.
