Rationale: The effects of BCG vaccination have been only sporadically studied in the elderly, and the long-term effects of the vaccination have not been studied until now. There is evidence that BCG vaccination beneficially influences susceptibility and severity of infectious and inflammatory diseases; however, the specifics, extent and duration of these effects are not known yet. With this observational study we would like to determine the extent of these effects in the elderly. Objective: To identify any long term effects of BCG vaccination on the incidence of infectious and inflammatory diseases may have in the elderly Study design: Cohort study with a duration of 5 years Study population: Older adults who participated in two large randomized BCG vaccination trials in 2020/2021 (BCG-CORONA-OUDEREN, BCG-PRIME), who have consented to be contacted for further studies Main study parameters/endpoints: The incidence of infectious and inflammatory diseases in the placebo- vs. BCG-vaccinated individuals
The Radiologically Isolated Syndrome (RIS) is defined as incidental Magnetic Resonance Imaging (MRI) abnormalities fulfil the criteria for dissemination in space, suggestive of multiple sclerosis. Nowadays, mandatory vaccination in patients with multiple sclerosis (MS) is widely recommended. Regarding COVID19, the absence of specific warnings led to the proposal of vaccination in patients with inflammatory diseases of the central nervous system. We aimed to evaluate if COVID19 vaccination or infection increased the risk of clinical conversion to multiple sclerosis or evidence of disease activity (EDA) in a cohort of RIS subjects.
The study was designed to analyze the efficacy and safety of Paxlovid for the treatment of COVID-19.
This is a randomised controlled clinical trial to determine the reactogenicity and immunogenicity of booster doses of SARS-CoV-2 vaccines (Pfizer-BioNTech, AstraZeneca or Moderna) in adults who have previously received either AstraZeneca or Coronavac as their primary doses. Both fractional and standard doses of Pfizer-BioNTech, AstraZeneca and Moderna will be tested.
This study is to clarify the distribution characteristics, host and clinical characteristics, disease outcome and risk factors, changes of multiple organs such as cardiopulmonary function and changes in social and psychological indicators during long-term follow-up of omicron variant asymptomatic infections and diagnosed patients
Recent advances have been made in prevention of the viral infection via vaccines but there is still need for effective treatment options for patients. Novel therapies need to be developed to further improve clinical outcomes. The biggest medical challenge in the response to COVID-19 is ARDS requiring hospitalization in an intensive care setting and ventilator dependence. Intravenously administered umbilical cord derived exosomes and stem cells have been reported in literature to alleviate pulmonary distress in such patients. The purpose of this study is to explore the safety and benefits of intravenous administration of WJPure and EVPure in the treatment of COVID-19 patients with moderate to severe ARDS. .
Urgent vaccine development plus the characteristics of the coronavirus have caused the relatively more safety problems in COVID-19 vaccines than other classic vaccines and unavoidably raises more concerns among those who accept or consider to be vaccinated. Mulberry juice consists of a large amount of anthocyanin. The abnormally high interleukin-17A level is frequently seen in patients with inflammation status or diseases with inflammation features. Some specific anthocyanins can reduce cyclooxygenase and nitrogen oxide, and the pharmacological effect of the major anthocyanin in mulberry juice imitates that of interleukin-17A antagonists. These features make mulberry juice a potential crude material for reducing inflammation and pain induced by COVID-19 vaccinations. The investigators propose a randomized control trial to explore the dose-response effects of three different volumes of mulberry juice on the incidence and severity of COVID-19 induced side effects. The findings should be helpful for nutrition supplementation in COVID-19 vaccinations and may improve public coordination of COVID-19 vaccinations.
The COVID-induced fibrotic lung damage continues long after viral infection has subsided and is exhibited by severe respiratory pathology and concomitant symptoms. The long-lasting sequelae in patients who have recovered from severe COVID indicate that there is a 30% chance of developing a persistent respiratory system pathology and a 10% chance of developing a severe pathology. The symptoms of lung fibrosis include a severe disruption of respiration, reduction of exercise tolerance, and concomitant development of persistent fibrotic lung damage. This study intends to evaluate benefits of a combination of WJPure and EVPure in Covid-19 patients exhibiting pulmonary fibrosis.
FUNCTION is an observational cohort study conducted by researchers from the Instituto de Medicina Tropical Alexander von Humboldt at Universidad Peruana Cayetano Heredia and Cayetano Heredia Hospital. The overall aim is to asses the long-term impact of SARS-CoV-2 infection on the cardiopulmonary function and quality of life in patients recovered from COVID-19, through a 6-month follow-up structured in 4 visits with clinical assessments and imaging studies performed by specialists.
The purpose of this clinical trial is to learn about how study medicine (Paxlovid, which contains nirmatrelvir and ritonavir) is changed and eliminated from the body, as well as its safety, and the extent to which side effects can be tolerated for treatment of pregnant women with mild or moderate COVID-19 compared to non-pregnant women with mild or moderate COVID-19. This study is seeking participants who: - are expecting a healthy baby and are in their second or third trimester pregnant and have mild or moderate COVID-19 - are not pregnant and have mild or moderate COVID-19. All participants in this study will take Paxlovid by mouth every 12 hours for 5 days (10 doses total). We will examine the experiences of people receiving the study medicine. This will help us determine if the study medicine is safe. All participants will take part in this study for at least 34 days; pregnant participants will take part until their delivery, so that the study duration may be up to 6 months, depending on their delivery date. During this time, participants will have 7-8 visits and, if pregnant, a visit at delivery. 2-3 visits and the delivery visit will be done in person (at the clinic or at the participant's home). The other 5 visits may be done over the phone, unless an in-person visit is necessary as determined by the investigator. Blood samples will be collected on the first 4-5 study visits (and at other study visits, if necessary). Some blood samples may be taken by participants themselves.
