Post-COVID-19 Monitoring in Routine Health Insurance Data With Focus on Autoimmune Diseases (POINTED-AD)...

Virus Diseases

The SARS-CoV-2 (Severe acute respiratory syndrome coronavirus type 2) infection was in 2020 responsible for new disease related chronic conditions which have been referred to as Post-COVID. To date it is still unknown how common this condition is and how it might effect the working of the Immune system. The aim of the study is therefore to monitor the onset of autoimmune diseases in a large observational study consisting of German health insurance data.

Respiratory Viral Infections During Acute Myeloid Leukemia (AML)Chemotherapy Related Aplasia

Acute Myeloid Leukemia

Infectious morbidity and mortality is a major complication of AML (Acute Myeloid Leukemia) induction and consolidation chemotherapies related aplasia. The main aim of this study is to measure incidence of respiratory viral infections during AML induction and consolidation chemotherapy related aplasia. Primary end point is a positive polymerase chain reaction(PCR)associated with clinical signs.

A Study to Find Out if the New Ebola Vaccine is Safe and Stimulates Immunity That Might Protect...

Ebola Virus Disease

Previous Ebola outbreaks have been limited to individual countries and contained by infection control activities. The current outbreak in West Africa is international, and air travel has resulted in a number of infected travellers crossing national borders. There are currently no specific treatments generally available for Ebola and the mortality is high, particularly in countries with limited intensive care facilities. There is currently no vaccine and the personal protection required by healthcare workers treating patients is cumbersome and requires full compliance to be protective. There is now a consortium (VEBCON collaboration) of four clinical centres (in Kenya, Gabon, Switzerland and Germany), WHO and New Link Genetics (the vaccine manufacturer) under which this study will be conducted. The investigators are conducting this trial, a Phase I, open-label, dose escalation trial, designed to establish safety, tolerability and immunogenicity of two doses of VSVΔG-ZEBOV, an Ebola Virus Vaccine Candidate for the first time in sub-Saharan African populations. The investigators plan to vaccinate 40 volunteers in Kenya. The trial will be conducted at the KEMRI-CGMR Coast site where healthcare workers (both clinical and laboratory) will be the primary target population as they are likely to be the recipients of a protective vaccine. The investigators will vaccinate a cohort of 20 volunteers at a low dose and then vaccinate a further cohort of 20 volunteers at full dose. Each volunteer will receive one dose of the vaccine. The investigators will follow them up for a period of one year looking to their safety and immunogenicity endpoints.

Observational, Prospective Clinical Study to Evaluate Biomarkers as Indicators of Acute Bacterial...

LRTIUTI3 more

This is an observational prospective study of an in-vitro diagnostic (IVD) assay planned to enroll 632 subjects. The study will be conducted in two stages: Stage A is aimed at identifying individual biomarkers and constructing a multi-parametric diagnostic model, whereas Stage B is aimed at testing the multi-parametric diagnostic model using a fresh cohort of patients. A collection of clinical, radiological and laboratory data will be gathered in order to establish a final diagnosis. Blood samples will be analyzed and the levels of approximately 700 and 250,000 biomarkers will be determined using immunoassays and molecular measurements respectively. A final diagnosis will be determined based on a majority decision of a panel of three or more independent physicians. Based on the final diagnosis, the accuracy of individual biomarkers and combined sets of biomarkers for differentiating between distinct groups of patients will be evaluated.

Surveillance Study of Viral Infections Following Lung Transplantation

Lung TransplantationBronchiolitis Obliterans2 more

The present study was conducted to study the impact community acquired respiratory virus (CARV) infections in an outpatient setting on graft function of lung transplant recipients. The study was aimed to identify risk factors for CARV infections. The study was further intended to investigate an association of Epstein-Barr virus (EBV), cytomegalovirus (CMV) and human adenovirus (HAdV) with the development of BOS and to identify risk factors for virus detection in blood.

Role of Cytokines in Hepatitis E Virus Infection During Pregnancy

HepatitisCytokines1 more

Hepatitis E virus is a public health problem in several countries of the world where safe drinking water is a problem. HEV is an exclusive cause of epidemic hepatitis in general population. HEV infection occurs most frequently in rainy season. The disease affects mainly young adults in the age of 15-40 years.HEV viral infection is of particular concern in pregnancy. It is a potential disaster for mother and child. HEV infection during pregnancy is fulminant and fatal especially if it occurs in third trimester. The mortality in the second trimester is around 20% and reaches upto 45% in the third trimester.

Viral Infections in Chronic Obstructive Pulmonary Disease (COPD) Exacerbations

Pulmonary DiseaseChronic Obstructive4 more

The objectives of the study are to determine the prevalence of respiratory virus infections in COPD patients, during and outside acute exacerbation to explore the impact of these viral infections on the outcome of these patients to explore the association between blood procalcitonin levels and viral infections in this population.

The Impact of the Previous Exposure to Covid-19 Virus Infection on the Outcome of ICSI Cycles

COVID-19IVF

Whilst the global COVID-19 pandemic is still evolving and there are many unknowns about the long-term effects of the virus on fertility and pregnancy, we found ourselves in need to offer some evidence-based guidance, that's why we decided to go for this study, to evaluate the relation of the covid-19 and the outcome of IVF/ICSI cycles. we found that there is no clear evidence that the previous exposure to Covid-19 virus infection can affect the outcome of ICSI cycles significantly.

A Phase I Study to Assess Ebola Vaccines cAd3-EBO Z and MVA-EBO Z

Ebola Virus Disease

This is a clinical trial in which healthy volunteers will be administered experimental Ebola vaccines. The investigators will vaccinate four groups of volunteers. Group one will receive the MVA-EBO Z vaccine once at the dose of 1 x 10^8 pfu. Three groups will receive the prime vaccine cAd3-EBO Z followed by the boost vaccine, MVA EBO Z. The second group of volunteers will receive the boost vaccine after 14 +/-7 days at a dose of 1 x 10^8 pfu and the third and fourth group, after 28 +/- 7 days but at different concentrations of MVA-EBO Z (1 x 10^8 pfu for group 3 and 1.5 x 10^8 pfu for group 4). The study will assess the safety of the vaccinations, and the immune responses to vaccination. Immune responses are measured by tests on blood samples. The cAd3-EBO Z and MVA-EBO Z vaccines are called viral vectored vaccines. They are made from viruses which are modified so that they cannot multiply. The viruses have extra DNA in them so that after injection, the body makes Ebola proteins (but Ebola does not develop), so that the immune system builds a response to Ebola without having been infected by it. Healthy volunteers will be recruited in Oxford and London England. The study will be funded by the Wellcome Trust.
