Active clinical trials for "COVID-19"

The global pandemic caused by the SARS-CoV-2 virus is confronting the German health system with a novel pathogen. This means that a timely evaluation of all available results is required. In the field of intensive care in particular, there are significant gaps in knowledge, particularly with regard to delirium. In this respect, this study also serves directly to investigate the pathways of delirium outcome in COVID-19 patients.

The objective of the COVID-19 Vaccines International Pregnancy Exposure Registry (C-VIPER) is to evaluate obstetric, neonatal, and infant outcomes among women vaccinated during pregnancy with a COVID-19 vaccine. Specifically, the C-VIPER will estimate the risk of obstetric outcomes (spontaneous abortion, antenatal bleeding, gestational diabetes, gestational hypertension, intrauterine growth restriction, postpartum hemorrhage, fetal distress, uterine rupture, placenta previa, chorioamnionitis, Caesarean delivery, COVID-19), neonatal outcomes (major congenital malformations, low birth weight, neonatal death, neonatal encephalopathy, neonatal infections, neonatal acute kidney injury, preterm birth, respiratory distress in the newborn, small for gestational age, stillbirth, COVID-19), and infant outcomes (developmental milestones [motor, cognitive, language, social-emotional, and mental health skills], height, weight, failure to thrive, medical conditions during the first 12 months of life, COVID-19) among pregnant women exposed to single (homologous) or mixed (heterologous) COVID-19 vaccine brand series from 30 days prior to the first day of the last menstrual period to end of pregnancy and their offspring relative to a matched reference group who received no COVID-19 vaccines during pregnancy.

Patients with chronic rheumatic diseases (such as systemic lupus erythematosus [SLE], rheumatoid arthritis [RA], ankylosing spondylitis [AS], juvenile idiopathic arthritis [JIA], poly/dermatomyositis [PM/DM], systemic sclerosis [SSc], systemic vasculitis, and primary Sjögren's syndrome [pSS]) are particularly susceptible to infectious diseases due to autoimmune disorder itself and its treatment (immunosuppressive therapies). Similarly, people living with HIV/AIDS (PLWHA) are predisposed to infections by different agents. The current 2019 Coronavirus Disease Pandemic-19 (COVID-19), caused by the SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) began in December 2019 in Wuhan, China, and quickly became a global health and economic emergency by taking to an unprecedented burden on health systems around the world. However, SARS-Cov-2 infection raised particular concern in patients with autoimmune rheumatic diseases (DRAI) since, due to chronic inflammatory immune dysregulation and the regular use of immunosuppressive drugs, these patients are considered to be at high risk of contracting SARS-CoV-2 and potentially evolving to a worse prognosis. The overlap between the COVID-19 pandemic and the HIV/AIDS pandemic also poses an additional challenge, as the impact of co-infection is not yet fully known. The response to vaccines for other agents, however, has already been described as compromised in PLWHA. Vaccination is the most effective preventive measure to control the spread of coronavirus and to reduce associated complications. Usually, live or attenuated vaccines are not recommended for patients with chronic rheumatic diseases using immunosuppressants. However, immunization with inactivated agents is strongly indicated, resulting, in general, in good immunogenicity and adequate vaccine safety, as well as without relevant deleterious effects on diseases. Vaccine efficacy studies are needed to verify the immunogenicity of the vaccine against COVID-19 in immunosuppressed patients with rheumatological disease and those with HIV-related disease considering the risk of greater severity. In addition, it is important to assess the safety of the vaccine in this population as well as the possibility of reactivating the rheumatological disease itself. The present study will evaluate the safety and immunogenicity of the CoronaVac (Coronavirus vaccine, Sinovac Biotech Ltd.) in patients with rheumatic diseases and PLWHA

The primary objectives of the study are: To assess the safety profile of the study vaccines in each study intervention group. To assess the neutralizing antibody profile after primary series vaccination in SARS-CoV-2-naïve adults. To demonstrate that a booster dose of monovalent or bivalent SARS-CoV-2 vaccine given to adults previously vaccinated with an authorized/approved COVID-19 vaccine induces an immune response that is non-inferior to the response induced by a twodose priming series with the monovalent vaccine, and superior to that observed immediately before booster. The secondary objectives of the study are: To assess the neutralizing and binding antibody profiles after primary series vaccination at pre-defined time points during the study. To assess the neutralizing and binding antibody responses of booster vaccination. To describe the occurrences of laboratory-confirmed symptomatic COVID19 after primary series and booster vaccination. To describe the occurrences of serologically-confirmed SARS-CoV-2 infection after primary series vaccination.

COVID-19, the coronavirus disease caused by SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2), has led to a global pandemic and has exacerbated existing health inequities among vulnerable populations. Despite higher rates of COVID-19 in Black and Latinx individuals compared to White individuals, rates of testing in predominately non-White, low-income communities are significantly lower than in high-income areas. Self-testing, where individuals collect their own samples, is now feasible for the detection of SARS-CoV-2. One promising approach to increase test uptake is the secondary distribution of self-testing kits, where an individual distributes tests to contacts in their social network and encourages them to self-test. The central hypothesis of this clinical trial is that the secondary distribution of SARS-CoV-2 self-tests can significantly expand test uptake among underserved populations. To test this hypothesis, the investigators will conduct a 1:1 randomized controlled trial that will assess a self-testing intervention that promotes the secondary distribution of SARS-CoV-2 test kits compared with test referrals, with a focus on reaching underserved populations.

Emerging clinical details of the current SARS-CoV-2 pandemic have illustrated that there are multiple clinical presentations and outcomes of this viral infection. People with an infection have been reported to have a spectrum of disease from severe acute respiratory distress requiring ventilation, to mild respiratory or gastrointestinal symptoms and asymptomatic presentations. Mechanisms explaining the heterogeneity of host response to infection are yet to be characterised. The aim of this project is to understand the host immune response to infection with SARS-CoV-2 over time in convalescent adults, including acquired immune responses, circulating levels of immune signalling molecules, gene expression profiling in peripheral blood and to identify host genetic variants associated with disease progressions or severity. Participants will be healthcare workers who had a diagnosis of COVID-19 (confirmed by positive RT-PCR assay) more than 28 days ago and have recovered and are employed by Cwm Taf Morgannwg University health board. Samples will be processed and analysed to explore immunological, host genetic factors and virological factors that explain pathogenesis and predict outcomes of infection.

Historically, health disparities in the US are concentrated among underserved communities and socially vulnerable populations. The disproportionate COVID-19 related morbidity and mortality in communities of color and socioeconomic disadvantage acutely highlight this persistent public health problem, drawing attention to the urgent need for more equitable reach of testing, prevention, and control measures. The proposed research addresses this need using a 2-arm randomized controlled trial (RCT) that will evaluate the effectiveness of the Nurse-Community Health Worker (CHW)-Family Partnership intervention in promoting COVID-19 testing uptake, adoption of COVID control measures, and mutual aid capacity at the household level in an underserved and vulnerable population disproportionately affected by COVID-19. Enrolled households will be randomly assigned to either the intervention group where families will receive the Nurse-CHW-Family Partnership intervention including the offer of in-home testing and referral to seasonal influenza vaccination services, or the treatment-as-usual control group, which will be used to measure actual testing rates among public housing residents in relation to participant and household characteristics. The study hypothesis is that the Nurse-CHW-Family Partnership intervention will improve household-level COVID-19 testing uptake, adoption of COVID control measures, and mutual aid capacity relative to the treatment-as-usual control.

To investigate short- (3 and 8 weeks) and long-term (6, 9, 12, and 18 months) immune protection or response at the humoral and cellular levels before and after SARS-CoV-2 infection or vaccination in patients with moderately reduced immune status (dialysis patients) and severely reduced immune status (organ transplant recipients, mostly kidney transplant recipients) and immunocompetent subjects (medical staff) in Saxony, Germany.

This study investigates a new diagnostic test in detecting SARS-CoV-2, the virus that causes the disease COVID-19. This may help to improve testing for COVID-19.

The COVID-19 crisis began in China in December 2019 and was declared a pandemic by the World Health Organisation on March 11th 2020. The pandemic has changed the way that clinicians interact with and treat patients overnight. Staff within the NHS will be under high levels of stress due to the increased needs and worse outcomes of work as they are shielding or self-isolating and may feel helpless and guilty. The psychological impact of the pandemic will be prolonged and varied. It is vital that Investigators increase understanding as much as possible to support NHS staff. The aim of this survey is to examine the possible mental health burden on NHS staff as a result of the COVID-19 pandemic and how these change as the pandemic progresses. By understanding these effects, it will allow researchers to identify recommendations to allow support mechanisms to be put in place for NHS staff, to better manage this and future pandemics and similar crises. Investigators are aiming to sample several cohorts of NHS staff including a subset of staff who are shielding. Staff will be asked to complete a series of online surveys at multiple timepoint: on study initiation, 1 month later and then 3 months after the pandemic has ceased in the UK. Additional timepoints may be added depending on the length and severity of the pandemic. The main outcomes will be tracking changes in mental health measurements at the pre-defined timepoints. This work will allow Investigators to produce recommendations about the increased mental health support that NHS staff will need. If a need is demonstrated then an interventional research project will be designed and implemented.
