Filter by:The purpose of the study is to design and execute a prospective, longitudinal, descriptive cohort study in a pragmatic clinical practice for adults with symptoms that may be related to COVID-19.
A rapid oxygen desaturation has observed in patients with COVID-19 which have seriously respiratory failure and most of them have intubated and connected to the mechanical ventilator. Finally, many of them have died during the process. ORF8 and superficial glycoproteins of a novel coronavirus bind to porphyrin on haemoglobin molecules and inhibit heme metabolism in an erythrocyte. However, it is not clarify the effects of the novel coronavirus on mean corpuscular volume (MCV), mean corpuscular of haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC).
This is a prospective study, involving contacting potential plasma donors and the use of their plasma to help fight off infections of those suffering from COVID19 in accordance to collection guidelines for plasma and FDA IND requirement. This study will include up to 240 participants potentially receiving convalescent plasma and up to 1000 potential donors. There are 3 basic arms to the study: mild, moderate and severe/critical severity. All 3 severity groups are eligible for enrollment, but mild severity will not be given plasma unless there is progression. Moderate severity will given up to 1 unit of plasma and severe/critical severity up to 2 units. There is no placebo group, however given the excepted issues of shortages of plasma, intention to treat will be used for analysis.
This study aims to observe the long-term health-related quality of life (HRQOL) and physical performance in individuals hospitalized due to a COVID-19 infection. Therefore, data is extracted from a study-site standard aftercare program which has been adjusted for this patient population. This comprehensive aftercare program includes education sessions and physical exercise. A second aim is to observe adherence and feasibility to the program and if indicated compare the clinical data and outcomes from patients following the program with patients denying to participate in guided exercise and education sessions. It is expected that patients hospitalized due to COVID-19 infection show a reduction in physical performance and HRQOL directly after discharge. The severity of illness is hypothesized to be associated with a reduction as well in HRQOL and physical performance after one-year post-discharge.
SARS-CoV-2 belong to beta-coronavirus family and its transmission route and symptoms follow those of all community-acquired coronaviruses. The main difference of the novel Coronavirus is the higher mortality rate, that is around 3%. Death rate is over 1% only for patients over 50 years old, whereas until 40 years old is under 0,4%. No fatalities are declared among children under 10 years old to date. Death rate is almost double for male rather than female. This distribution of mortality rate according to age of infected patients could be only partially ascribed to other comorbidities in addition to great age. In fact, patients with no pre-existing conditions have however a case fatality rate of 0,9%. The almost null rate of severe illness in children and generally in patients younger than 40 years old is quite un-explicable. Infant, children and young people could be infected but infection is rapidly self-limited or without symptoms. Older patients undergo severe lung injury as consequence of an immune response that is late in coming. Possible explanation of these phenomena could be something, which assure ability to prompt response to SARS-CoV-2 in younger people independently from the novelty of the virus itself. It would seem to be that younger people are already sensitized to the antigens of the virus without a previous contact. This immunity is not really specific, but "partially specific" for many antigens of the virus, however able to limit the infection in the organism. Something stimulated the immune system and it scattered immunity against more and more antigens present. Children are the age group mostly exposed to all community-circulating viruses. This immunity is not persistent but progressively fade out. It protects from the age of two, when the hypothetical stimulation occurs, to the fifth decade because of its slow decrease. The only external stimulation, which healthy people receive are vaccines. All vaccinations and especially tetanic, diphtheria toxoids and inactivated bacteria as pertussis could stimulate immune system. They develop the specific immunity but generate also a sprouting immunity against antigens in transit, as coronaviruses and other community-circulating viruses. The developed immunity gives some protection against multiple viral infection for years until the natural fade out. After the fifth decade, that immunity is slower to be recall and reactivated. Additionally, transplant recipients and HIV infected patients, which have an immune system inhibited, unexpectedly, do not seem to suffer the worst complications of SARS-CoV-2 infection. An immune system imbalance could be play a pivotal role during the reaction to the virus, limiting destructive consequences of excessive inflammation. According to the medical hypothesis on which the protocol is based on, young people could benefit from a functional adaptation of innate immune cells induced through epigenetic reprogramming and, especially, a pre-existing "partially specific" immunity to the community viruses caused by "bystander effect" of preceding vaccinations. In this study, we will explore the main differences existing among patients infected by SARS-CoV-2 who experience the illness at different degree of severity. We suppose to recognize different populations of patients, each one with a specific immunological pattern. It could differ in terms of cytokines, soluble factors serum level and immune cells activity both of the innate compartment and of the acquired one. The proof of a role of these immunological phenomena in the pathogenesis of Covid-19 are bases for implementation of therapeutic immunomodulatory treatments. In addition, the definition of an immunological risk profile could tailor established therapies to each kind of patient.
The aim of this study is to determine the risk factors for development of ventilator-associated pneumonia (VAP) and to identify the prognostic factors of VAP among Coronavirus Disease 2019 (CoViD-19) patients. We hypothesized that CoViD-19 serves as a high risk factor for the development of VAP and it affects clinical outcome measures negatively.
Patient are being asked to provide respiratory and blood samples for a clinical research study because the patients have a virus called the novel coronavirus, or SARS-CoV-2, that causes the disease known as Covid-19. Investigators do not know a lot about this virus, including all the ways it travels from person to person. Investigators also do not know if a person will get sick or not from the virus after being in close contact with someone who has the virus. Because of this, investigators are performing research on the virus found in respiratory secretions to get more information on how investigators can best detect and treat this new virus in the future. Primary Objective - To determine the clinical characteristics and outcomes of Covid-19 in children. - To characterize the clinical risk factors of Covid-19 in children.. Secondary Objectives - To characterize the immunological risk factors and serologic response to SARS-CoV-2 infection in children.- To evaluate the duration of viral shedding in children. - To evaluate the duration of SARS-CoV-2 viral shedding in children. Exploratory Objective
Hungarian CoronaVirus disease-19 Epidemiological Research
The novel coronavirus (SARS-CoV-2) has spread all around the world and testing has posed a challenge globally. Health care providers are highly exposed and are an important group to test. On top of these concerns, health care workers are also stressed by the needs on responders in the COVID-19 crisis. The investigators will look at different ways to measure how common COVID-19 is among health care workers, how common is the presence of antibodies by serological tests (also known as serostatus). The investigators will describe health worker mental and emotional well-being and their coping strategies in their institutional settings. Lastly, the investigators will describe how knowing serostatus can affect individuals' mental and emotional well-being and how to cope in the midst of the COVID-19 response. This will help to how to better test and help healthcare workers in the COVID-19 pandemic and prepare for possible future outbreaks.
