NCT ID: NCT04979091 Completed - Covid19 Clinical Trials

Sex Hormone Dysregulations Are Associated With Critical Illness in COVID-19 Patients

Start date: March 8, 2020
Study type: Observational

Males develop more severe SARS-CoV-2 infection related disease outcome than females. Herein, sex hormones were repeatedly proposed to play an important role in Covid-19 pathophysiology and immunity. However, it is yet unclear whether sex hormones are associated with Covid-19 outcome in males and females. In this study, we analyzed sex hormones, cytokine and chemokine responses as well as performed a large profile analysis of 600 metabolites in critically-ill male and female Covid-19 patients in comparison to healthy controls and patients with coronary heart diseases as a prime Covid-19 comorbidity. We here show that dysregulated sex hormones, IFN-γ levels and unique metabolic signatures are associated with critical illness in Covid-19 patients. Both, male and female Covid-19 patients, present elevated estradiol levels which positively correlates with IFN-γ levels. Male Covid-19 patients additionally display severe testosterone and triglyceride deficiencies as compared to female patients and healthy controls. Our results suggest that male Covid-19 patients suffer from multiple metabolic disorders, which may lead to higher risk for fatal outcome. These findings will help to understand molecular pathways involved in Covid-19 pathophysiology.

Nutrition, Immunity, and Covid-19 in Obese People

Start date: July 24, 2021
Phase: N/A
Study type: Interventional

The increased risk of transmission of COVID-19 infection causes the incidence of death in health workers to escalate. It requires further research on risk factors and intervention in health worker professionals, especially on immunity factors and nutritional status. Quality of diet and nutrition is very important to support the immune system when infected. Several probiotic strains have been shown to decrease the duration and incidence of diarrhea and respiratory infections, suggesting the Gut-Lung Axis pathway. Some probiotics also improve the balance of diversity in the composition of the gut microbiota and affect body weight in obese people. Probiotics have also been shown to improve vitamin D absorption. A combination of vitamin D and probiotics may be an alternative to reduce gut dysbiosis that will directly or indirectly reduce the risk and severity of viral infections including SARS-CoV-2.

NCT ID: NCT04978259 Recruiting - Covid19 Clinical Trials


Start date: July 21, 2021
Phase: Phase 4
Study type: Interventional

The primary aim of the SOLIDARITY Finland Long-COVID trial is to assess the long-term effects of remdesivir use during hospitalisation on long-COVID symptoms and quality of life (QoL) using questionnaires at one and two years post-discharge. The primary research questions are whether remdesivir lowers the risk of long-COVID symptoms and leads to better QoL in the long term. Objectives include: i) Long-COVID symptoms - To investigate the effect of remdesivir (vs. usual care only) on the occurrence of symptoms that have been associated with the long-COVID syndrome. The questionnaires will take place one and two years after the hospital admission. The questionnaire was developed by our multidisciplinary team of physicians, including the representation of multiple specialties such as general practice, lung diseases, neurology, internal medicine, rheumatology, genetics, and clinical epidemiology, and two patient partners. - The symptom questionnaire - that will be completed by patients at one and two years - measures basic patient information (age, height, weight, smoking status, major comorbidity, and working status) and a wide variety of potential long-COVID-symptoms and their bother (1. Fatigue; 2. Attention deficits; 3. Memory problems; 4. Sleeping difficulties; 5. Depressive mood; 6. Anxiety; 7. Dizziness; 8. Headache; 9. Tinnitus; 10. Paresthesias; 11. Changes in taste/smell perceptions; 12. Postexertional malaise; 13. Palpitations; 14. Chest discomfort; 15. Nausea; 16. Skin rash; 17. Joint aches; 18. Muscle pains; 19. Continuous cough; 20. Respiratory tract mucous discharges) in remdesivir and usual care arms ii) Quality of life - The EQ-5D-5L questionnaire will be used to compare patients' quality of life in remdesivir and usual care arms. - EQ-5D-5L questionnaire assesses the following domains: 1. Mobility; 2. Self-care; 3. Usual activities; 4. Pain and discomfort; 5. Anxiety and depression; 6. The visual analog scale of subjective perception of overall health. Additionally (at 1 or 2 years; depending on future funding and ethical approval decisions; currently the study has ethical approval for long-COVID and quality of life assessments only): - The Finnish healthcare registries (Statistics Finland Mortality Database and the HILMO Care Register for Health Care) will be used to estimate long-term mortality and incidence of major comorbidity in remdesivir and usual care arms - Lung function will be assessed using spirometry and diffusing capacity, as well as the six-minute walk test (6 mwt) in remdesivir and usual care arms - Whole-genome genotyping will be performed for a genome-wide association study to investigate genetic correlates of long-COVID-19 -symptoms in remdesivir and usual care arms

The Role of Frequent Point-of-care Molecular Workplace Surveillance for Miners

Start date: February 22, 2021
Study type: Observational

The long-term goal of the study is to mitigate the spread of the pandemic in miners, a population of high-risk, rural essential workers who are susceptible and vulnerable to COVID-19, partly based on exposure to particulate air pollution, and who are predominantly racial/ethnic minorities in New Mexico (NM) (3, 11). The study objective is to provide proof-of-principle for frequent point-of-care molecular testing as a workplace surveillance tool to monitor and prevent the spread of SARS-CoV-2 infection in this unique population. The central hypothesis is that frequent workplace molecular surveillance is an effective method to reduce SARS-CoV-2 infection and discover novel host risk factors for the virus. The site of molecular surveillance (intervention site) will be a surface coal mine in McKinley County, NM, located just outside the Eastern Agency of the Navajo Nation, comprised of 66% minority miners. This site offers a unique opportunity for a community-based study of SARS-CoV-2 infection in this population. Miners at the intervention site will provide nasal swabs before beginning their work shift on alternate days that will be analyzed with a 'screening' molecular test (12). This test is ideal because it is low cost, simple, portable, point-of-care, rapid, and can be performed by minimally trained professionals in low-infrastructure settings. The control site is a similar coal mine in Campbell County, Wyoming (WY). Both mines, operated by the same company, have similar engineering, administrative, and personal protective measures in place. The rationale for this study is to establish the suitability of longitudinal molecular surveillance to prevent and control SARS-CoV-2 infection in this unique population by completing the following specific aims.

NCT ID: NCT04977024 Not yet recruiting - Lymphoma Clinical Trials

SARS-CoV-2 Vaccine (COH04S1) Versus Emergency Use Authorization SARS-COV-2 Vaccine for the Treatment of COVID-19 in Patients With Blood Cancer

Start date: August 1, 2021
Phase: Phase 2
Study type: Interventional

This phase II trial studies the immune response to COH04S1 compared to Emergency Use Authorization (EUA) SARS-COV-2 vaccine in patients with blood cancer who have received stem cell transplant or cellular therapy. COH04S1 belongs to a category called modified vaccinia Ankara (MVA) vaccines, created from a new version of MVA, called synthetic MVA. COH04S1 works by inducing immunity (the ability to recognize and fight against an infection) to SARS-CoV-2. The immune system is stimulated to produce antibodies against SARS-CoV-2 that would block the virus from entering healthy cells. The immune system also grows new disease fighting T cells that can recognize and destroy infected cells. Giving COH04S1 after cellular therapy may work better in reducing the chances of contracting coronavirus disease 2019 (COVID-19) or developing a severe form of COVID-19 disease in patients with blood cancer compared to EUA SARS-CoV-2 vaccine.
