Filter by:The primary objective of this clinical performance study is to evaluate and further validate the clinical performance of: 1. ClariLight Influenza A/B & SARS-CoV-2 test kits and 2. ClariLight Influenza A/B & RSV test kits, for the qualitative detection and differential diagnosis of SARS-CoV-2, influenza A, influenza B, and respiratory syncytial virus (RSV) present in anterior nasal and oropharyngeal swab, in combination with an automated molecular diagnostic analyzer and sample collection tube by comparing them against a CE marked, in-vitro diagnostic device, used in the standard of care.
The goal of this clinical trial is to compare treatment with oral Paxlovid (nirmatrelvir/ritonavir) and placebo for acute COVID-19 as an intervention to prevent long-COVID (post-COVID-19 condition) in adults aged 18-64 years old. The main question it aims to answer is: Does treatment with Paxlovid for acute COVID-19 reduce the prevalence of long-COVID compared to placebo. Participants with acute COVID-19, documented with positive lateral flow test or PCR, within the last 5 days will be randomised to take either Paxlovid or placebo. All participants will receive standard of care in addition. Participants will respond to electronic questionnaires at 14 time points during follow-up. The primary outcome is presence of long-COVID symptoms at 3 months follow-up. Researchers will compare participants who received Paxlovid and placebo to see if Paxlovid treatment can prevent the occurrence of long-COVID.
The primary objective of this study is to evaluate the safety and tolerability of intravenous (IV) IMM-BCP-01 in subjects with mild to moderate COVID-19 through Day 28. The secondary objectives of the study are to: - Determine pharmacokinetics (PK) and evaluate viral clearance after single ascending doses of IV IMM-BCP-01 in subjects with mild to moderate COVID-19 through Day 28. - Evaluate the safety and tolerability, determine PK, and evaluate viral clearance of single ascending doses of IV IMM-BCP-01 in subjects with mild to moderate COVID-19 through Week 12.
The prevalence and clinical relevance of viremia in patients with COVID-19 have not been well investigated. Seeking to understand the need for dentistry to perform bloody procedures in critically ill patients with COVID-19 admitted to the ICU, the quantification of the magnitude of viral replication may play a fundamental role in this scenario. For this, it is necessary to study the viremia kinetics of SARS-CoV-2, seeking to assess whether there is any characteristic pattern that may be associated with a worse clinical outcome of the patient with COVID-19 after undergoing bloody dental procedures, therefore, the objective of this research will be to investigate the occurrence of viral kinetics produced by dental procedures in patients with SARS-CoV-2 in Intensive Care Units, where, in addition to analyzing the oral health condition, the viral kinetics of SARS-CoV-2 will also be investigated by means of reverse transcription polymerase chain reaction (RT-PCR) examination of blood samples from patients with COVID-19 undergoing bloody dental treatment. This research is expected to identify risks and consequences regarding the possibility of performing bloody dental treatment in patients with COVID-19 in serious condition, in addition to verifying the association of the impact of oral infection foci on this profile of patients.
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.
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.

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;
