A randomized, observer-blind, placebo-controlled immuno-bridging, and broadening study to demonstrate the equivalence of the immune response between participants enrolled in Phase 3 efficacy trial in India and demographically diverse healthy adult participants in the US which matched in age and vaccine formulation setting to whom those efficacy results are extrapolated; and to assess the broadening of the BBV152 in participants who previously received two shots of messenger ribonucleic acid (mRNA) COVID-19 vaccine at least 6 months earlier or one-shots of viral vector J&J/Janssen COVID-19 vaccine at least 2 months earlier. Safety and tolerability evaluation is a secondary endpoint.
The current study is an open, non-randomized, monocentric, and interventional study. CoViD-19 patients will be recruited at UZ Brussel after informed consent is obtained. Whole blood and serum samples will be collected during acute disease (inclusion and 7 days after inclusion) and during patient follow-up at 2 months after infection. Sample storage and subsequent use in fundamental research will be performed at VUB Neuro-Aging and Viro-Immunotherapy. Additionally, medical records of UZ Brussel will be searched and epidemiological, clinical, radiological, and biological data of the selected patients will be obtained at the diagnosis time point and during follow-up. Healthy volunteers will be recruited as well in the current study, as a comparison arm, after informed consent is obtained.
Multicenter observational retrospective cohort study aiming at comparing the incidence of ventilator-associated lower respiratory tract infections between COVID-19 patients from the first and the second wave of the pandemic.
Primary objective: - To evaluate the efficacy of oral reparixin versus standard care alone in limiting disease progression in adult patients hospitalised for infectious pneumonia acquired in the community (CAP), including COVID-19. Secondary objectives: - To determine the effect of reparixin on several disease severity/progression measures including recovery, ventilatory free days and mortality. Safety objectives: - To evaluate the safety of oral reparixin versus placebo in the specific clinical setting.
This pilot open-label randomized controlled trial aims to assess if treatment with sulodexide may improve the endothelial status and inflammatory response in post-COVID-19 patients. Survived inpatients with severe-to-critical COVID-19 within 14 days after discharge are randomized to receive sulodexide 250 LSU 1 oral capsule twice daily or no treatment for 8 weeks. Biomarkers of endothelial dysfunction, inflammation, and prothrombotic changes are assessed at 0, 4, and 8 weeks. The hypothesis is that affected endothelial function, pro-inflammatory, and pro-thrombotic changes could be improved with sulodexide treatment in convalescent COVID-19 patients who suffered a severe-to-critical clinical presentation and have chronic comorbidities of high risk for endothelial dysfunction.
Objectives and aim: To evaluate the long-term spill-over (indirect) effect of Coronavirus disease (COVID-19) on health outcomes and healthcare utilization among people with non-communicable diseases and without COVID-19. Design: A population-based cohort study using electronic health records of the Hospital Authority (HA) clinical management system, economic modeling, and serial cross-sectional surveys on healthcare service utilization. Setting: HA public hospitals and outpatient clinics in Hong Kong Participants: People aged ≥ 18 years with a documented diagnosis of diabetes mellitus, hypertension, cardiovascular disease, cancer, chronic respiratory disease, and chronic kidney disease; without COVID-19; attending HA services between 2010 and 2024. Main outcome measures: All-cause mortality, disease-specific outcomes, healthcare service utilization, and costs. Methods: The annual incidence of each outcome in each year between 2010 and 2024 will be calculated. An interrupted time-series analysis to assess the changes in outcomes between pre-and-post-COVID-19 outbreak periods. Long term health economic impact of healthcare disruptions during the COVID-19 outbreak will be modeled using microsimulation. Multivariable Cox proportional hazards regression and Poisson/negative binomial regression to evaluate the effect of different modes of care on the risk of the outcomes. Implications: Findings will inform policies and practices on contingency care plans to avoid excessive morbidity and mortality and to assure the quality of care for patients with NCD as part of the territorial response to the health crisis.
Respiratory failure associated with Covid-19 can be expressed as acute respiratory distress syndrome (ARDS), which is an acute inflammatory lung injury,which generally requires the use of invasive mechanical ventilation (MV). There are inconclusive results regarding the potential lung recruitment in ARDS. At the lung level, the relationship between lung volume and pressure can be graphed through a pressure/volume (P/V) curve. In this curve, hysteresis (H) can be evaluated, which is the amount of energy generated during inspiration that is not recovered during expiration. H is related to recruitment, assuming that the greater H the greater the alveolar recruitment. For this reason, the objective of this study is the measurement of H as a way to assess the lung recruitment capacity, in patients with ARDS and in patients with Covid-19 who develop ARDS (ARDS- Covid)
Background: Many adults and some children with COVID-19 or acute respiratory infection become critically ill and need advanced life support in the Intensive Care Unit (ICU). Frailty is a medical condition of reduced function and health. Adults with frailty have a lower chance of surviving critical illness. The investigators are still learning about critically ill adults with COVID-19 or acute respiratory infection, and do not have much information on how frailty affects outcomes in critically ill children, with or without COVID-19 or acute respiratory infection. Rehabilitation can help survivors of COVID-19 or acute respiratory infection by improving strength and improve quality of life (QOL). Objectives: The main goal of this research study is to see if patients with frailty have a lower chance of surviving COVID-19 or acute respiratory infection critical illness and more health problems after survival than patients without frailty. The investigators will also study the types of rehabilitation received by patients with COVID-19 or acute respiratory infection. Methods: The investigators will include adults and children with COVID-19 or acute respiratory infection who are admitted to the ICUs that participate in the study. The investigators will gather data about each patient, including before and during their illness. Outcomes: The investigators will collect level of frailty, function, and types of therapy, or rehabilitation received by patients. In adults, the investigators are most interested in learning if frailty influences mortality, or death. In children, the investigators are most interested in whether children with COVID-19 or acute respiratory infection critical illness are more likely to develop frailty. The investigators will also study post-hospital discharge location in survivors (e.g., home, rehabilitation). Relevance: The COVID-19 pandemic is a global public health crisis. It is critical to understand how COVID-19 and other acute respiratory infection critical illness affects groups of people who are at higher risk, and the impact on outcomes that are important to patients, like functioning and QOL. The results will help policy makers plan post-hospital services for survivors, help healthcare workers understand the importance of rehabilitation practice for patients with COVID-19 or acute respiratory infection, and help researchers develop treatments to improve QOL after COVID-19 or acute respiratory infection.
Over recent months, SARS-CoV-2 infection has been confirmed in millions of people around the world. Furthermore, the COVID-19 pandemic gives rise to new psychosocial and emotional stressors for recovering patients, including social isolation, physical distancing, loss of employment and uncertainties about the future. This project is aimed to propose an innovative comprehensive intervention based on a stationary pulmonary rehabilitation (PR) programme for COVID-19 survivors. Moreover, this project assumes the use of virtual reality (VR) in rehabilitation processes.
