Filter by:There is growing evidence that COVID-19 threatens maternal and perinatal health. Pregnant women are at higher risk of severe complications (severe pneumonia, hospitalizations, intensive care unit admission, invasive mechanical ventilation, extracorporeal membrane oxygenation) and death compared to age-matched non-pregnant women. On the other hand, the number of confirmed COVID-19 cases reported in sub-Saharan Africa (SSA) continues to increase, where the highest maternal mortality rates in the world are registered. The World Health Organization (WHO) estimates that this region alone accounted for roughly two-thirds (196 000) of all maternal deaths in 2017, which among other reasons is explained by the inequalities in access to quality antenatal care (ANC) services and the low numbers of skilled health workers in the region. The spread of SARS-CoV-2 in SSA is threatening the already fragile health services, affecting mainly the most vulnerable populations such as pregnant women. This project aims to describe the burden and effects of SARS-CoV-2 infection during pregnancy in women living in malaria endemic areas and high prevalence of HIV infection. Pregnant women attending ANC clinics in selected sites from Libreville and Lambaréné (Gabon) and Manhiça (Mozambique) will be enrolled in a cohort study to determine the frequency of SARS-CoV-2 infection and COVID-19 during pregnancy and its effects on maternal and neonatal health. Participants will be tested for SARS-CoV-2 infection whenever reporting respiratory symptoms suggestive of COVID-19 during routine ANC follow-up and six weeks after the end of pregnancy. The presence of antibodies (IgG/IgM) against SARS CoV-2 in blood samples will be determined. The clinical presentation of COVID-19 in pregnancy will be also characterised, and the incidence of infection during pregnancy and the risk factors of maternal and neonatal morbidity and mortality associated with SARS-CoV-2 infection and the frequency of mother- to- child transmission of SARS-CoV-2 will be assessed. The findings of this project will contribute to the understanding of the impact of SARS-CoV-2 and COVID-19 among pregnant women living in SSA countries where malaria and HIV infections are highly prevalent.
The Fluo-Pred-Iver clinical trial will test the efficacy of a combined regimen of Fluoxetine, Prednisolone and Ivermectin (Fluo-Pred-Iver), as treatment for ambulatory patients with mild COVID-19. The overarching idea of the work proposed herein is to investigate the use of Fluo-Pred-Iver to treat COVID-19, conducting a randomized controlled clinical trial to evaluate a new indication for these widely available drugs. It is estimated to include 954 participants.
The objective of this study is to evaluate the immunogenicity and safety of SCTV01C in participants aged ≥12 years and previously fully immunized with inactivated COVID-19 vaccine.
In COVID-19 infection caused by the Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), there is a dysregulation of the immune system response that causes cytokine storm syndrome. SARS-CoV-2 works like a hijacker (hackers), sabotaging communication between cells so that the immune system, like T-cells, kills not only infected cells but also healthy cells. This dysregulation results in hyper-inflammation which cause damage to organs, not just the lungs. This is the cause of the high mortality rate in COVID-19 patients. Exosomes are vesicles with a size of 30-100 nanometers originating from within cells that function to communicate with other cells. Exosomes are transport containers that contain bioactive cargo: such as proteins, genetic material, and various other molecules. These containers move from cells of origin, flowing through blood vessels or other body fluids to target cells. Exosomes penetrate the cell membrane and act on various organelles within the target cell. All cell types can produce exosomes. What differentiates them is the cargo they contain. The exosome produced by mesenchymal stem cells (MSCs) contains bioactive cargo derived from mesenchymal stem cells, such as anti-inflammatory cytokines, growth factors, messengerRNA (mRNA) and microRNA (miRNA). The target cells are immune system cells, infected cells and progenitor cells from infected organs. On target immune cells, the anti-inflammatory cytokines work as immunomodulators to relieve hyper-inflammation. In infected cells, the miRNAs work to prevent viral replication by inhibiting the expression of SARS-CoV-2 virus RNA (viral mRNA silencing and degrading). In lung progenitor cells and other infected organs, the growth factors work to stimulate protein synthesis processes that function for organ regeneration. This study is a multi-center, double-blind, randomized controlled trial (RCT) clinical trial with two arms: one intervention arm, and one control arm. The EXOSOME-MSC will be tested as adjuvant, on top of standard COVID-19 drugs. It will be injected to participants via intravenous route twice, in day-1 and day-7 of 14 days of study participation.
The main objective of the clinical study is to evaluate the efficacy of Zinc supplementation in non-critically ill Covid-19 patients..
This study aims to investigate the clinical performance characteristics of the novel point-of-care, semi-quantitative test for SARS-CoV-2 in the Emergency Department compared to the gold standard (ELISA).
Myopericarditis is a rare complication to messenger ribonucleic acid (mRNA) COVID-19 vaccines, especially in male adolescents and young adults. The risk in children 5-11 years old is unknown. In Denmark, the Pfizer-BioNTech mRNA COVID-19 vaccination was recommended from December 1, 2021 in individuals aged 5-11 years old. We aim to estimate the incidence of myopericarditis in children 5-11 years old after mRNA COVID-19 vaccination among vaccinated individuals based on a nationwide prospective population-based cohort study with detailed clinical phenotyping.
This study aims to investigate the epidemiology of SARS-CoV-2 infection among: i) HCW who triage patients with suspected SARS-CoV-2 infection and provide care to COVID-19 patients; and ii) laboratory personnel who test clinical samples for SARS-CoV-2 infection. After the second wave of the pandemic enrolment will be widen to any person working at the study hospitals.
This is a combined retrospective and prospective, longitudinal, observational meta-cohort of individuals who will enter the cohort with and without SARS-CoV-2 infection and at varying stages before and after infection. Individuals with and without SARS-CoV-2 infection and with or without Post-Acute Sequelae of COVID-19 (PASC) symptoms will be followed to identify risk factors and occurrence of PASC. This study will be conducted in the United States and subjects will be recruited through inpatient, outpatient, and community-based settings. Study data including age, demographics, social determinants of health, medical history, vaccination history, details of acute SARS-CoV-2 infection, overall health and physical function, and PASC symptom screen will be reported by subjects or collected from the electronic health record using a case report form at specified intervals. Biologic specimens will be collected at specified intervals, with some tests performed in local clinical laboratories and others performed by centralized research centers or banked in the Biospecimen Repository. Advanced clinical examinations and radiologic examinations will be performed at local study sites with cross-site standardization.
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. The SARS-CoV-2 pandemic has been accompanied with a substantial increase in the number of individuals presenting with new onset type 1 diabetes [1]. Most individuals presenting with type 1 diabetes since the start of the COVID-19 pandemic are SARS-CoV-2 antibody positive. These findings suggest that SARS-CoV-2 infection can cause type 1 diabetes. Investigators have identified that many individuals presenting with type 1 diabetes since the start of the COVID-19 pandemic are SARS-CoV-2 positive by swab or blood test. Researchers have also observed that T cells in patients who have had COVID recognise some of the peptides in the pancreatic islet cells, which are responsible for production of insulin. These findings suggest that SARS-CoV-2 infection may be associated with new onset of type 1 diabetes. The aim of this project is to understand the host immune response to infection with SARS-CoV-2 over time in convalescent newly diagnosed patients with type 1 diabetes, including acquired immune responses, gene expression profiling in peripheral blood and to identify host genetic variants associated with disease progressions or severity. Participants will have Type 1 diabetes and will have had a diagnosis of COVID-19 (confirmed by a positive nasopharyngeal swab PCR test and/or SARS-CoV-2 antibody test) and have recovered from COVID-19. Samples will be processed and analysed to explore the molecular mechanisms by which SARS-CoV-2 infection might precipitate immune attack on insulin-producing cells resulting in autoimmune diabetes.
