Active clinical trials for "Virus Diseases"

Investigators aimed to compare clinical and radiographic markers between SARS-CoV-2 positive and RSV positive infants

For the development of a Point of Care IVD test kit for acute phase disease detection against a variety of bacterial and viral infections. Phase one includes 100 clinical diagnosed positive and 200 clinically "normal" serum and whole blood matched specimens for specificity and sensitivity determination for each marker. The positive samples must be IgM positive using any FDA cleared ELISA test kit. The negatives samples must be negative for IgM.

The VRS (Respiratory Syncytial Virus) study group in Lyon is a working that aims to understand, predict and prevent the burden of disease caused by human respiratory syncytial virus (RSV) infection in infants. Incidence of RSV-associated hospitalization in the first year of life was estimated at 14.5 (95% CI 13.4-15.6) per 1000 births in a cohort study in Lyon, France. Related direct medical annual costs were estimated for this cohort at 364,269€, mostly attributed to children born during the RSV season (231,959€) and children born premature (108,673€). This study will combine existing hospital specimens and databases to determine the respective role of socio demographic factors, clinical risk factors, level of cord specific antibody at birth, and virus characteristic in the Respiratory Syncytial Virus (RSV) Hospitalization outcome in Infants. Regarding the introduction of a new RSV vaccine and RSV-specific neutralizing antibodies, these data are of prime importance to guide future vaccine policies.

Project is designed as a comprehensive population-based epidemiological study in Upper-Silesian Conurbation (Poland) aiming at: analysis of available data on incidence and mortality due to COVID-19 and estimation of the occurrence of viral infection SARS-CoV-2 as revealed by the results of serological test (ELISA: IgM, IgG), with assessment of risk factors. The project's objectives are: to assess incidence and mortality due COVID-19 according to sex, age and coexisting diseases; to determine the level of potential "underdiagnosis" of the magnitude of COVID-19 mortality using vital statistics data for Upper-Silesian Conurbation; to assess the prevalence of SARS-CoV-2 based on the level of seropositivity in Upper-Silesian Conurbation; to identify host-related and environmental risk factors if the infection. Analysis of existing data will include monthly records on incidence and mortality over the period 01.01.2020-31.12.2020 and comparison of the findings with the monthly records of 2018 and 2019, for the same population. Cross-sectional epidemiological study will be located in three towne (Katowice, Sosnowiec, Gliwice). In each town a representative age-stratified sample of 2000 subjects will undergo questionnaire assessment and serological examination performed by serological test. The project corresponds with analogous population-based studies on COVID-19 in a number of countries and responds to the WHO recommendation in that field.

Coronavirus 2019 (COVID-19) is a respiratory tropism virus transmitted through droplets emitted into the environment of infected persons. The symptoms can be extremely varied and the course can range from spontaneous healing without sequelae to death. Currently, the diagnosis of certainty for resuscitation patients (by definition "severe") is based on searching for a fragment of virus genetic material within the epithelial cells of the respiratory tree, up and/or down, by PCR. It is to be expected that the epidemic peak will make it difficult (if not impossible) to respect the stereotypical path that is currently in place, due to the lack of space in the specific unit. This will require optimization of care pathways and use of the specific sectors. It is therefore necessary to define the simple criteria, available from the moment patients are admitted, to predict the result of the COVID-19 PCR.

The Novel Coronavirus (2019-nCoV), also known as Wuhan coronavirus, causes the 2019-nCoV acute respiratory disease.

Respiratory Syncytial Virus (RSV) is the leading cause of chest infections (pneumonia and bronchiolitis) in young children, and is a major cause of admission to hospital and childhood death worldwide. One possible way to protect the mother and young infant from RSV infection is a vaccine given to women during pregnancy (maternal vaccination), which would pass protection to their unborn child. This may help to prevent RSV in the child's first few months of life when they are most vulnerable to infection. There are two main aims to this study: To pre-emptively gauge the knowledge of RSV and potential acceptability of such vaccines amongst pregnant women and healthcare staff working in midwifery and obstetrics, as well as their attitudes (facilitators and barriers) to being involved in hypothetical future research trials. We also wish to gauge the attitudes to routinely recommended vaccines in pregnancy (pertussis and influenza) The investigators propose to undertake a questionnaire-based study of randomly selected pregnant women and healthcare staff (over 16 years of age) at English teaching hospitals and GP practices. Pregnant women attending for ward reviews or antenatal clinics will approached and asked to complete an anonymous paper questionnaire lasting around 10 minutes. Healthcare staff will be approached in person, or via email, and asked to complete a slightly different questionnaire lasting around 5-10 minutes. No follow up will take place. Using statistical software, the investigators hope to identify factors that might affect patients' understanding of RSV and attitudes to being involved in hypothetical future trials and receiving routine vaccination

The XN-20, is a full blood count (FBC) analyser with an extended differential counting and flagging System. The XN-Series' individual channels allow real-time reflex analysis, and uses a two stage process to classify the white blood count (WBC) sub-populations and detect the presence of abnormal reactive and malignant cells. In regards to lymphocytes in the peripheral blood, the machine has the capacity to distinguish activated from non-activated T-cell subsets using a very small volume of EDTA sample (88uL) (including remnant sample from a standard full blood count) with results available in 1.5 minutes. It is a fully automated process and can be considered as an alternative rapid flow cytometry method. Objective of the SASA study: to investigate the signal pattern of white blood cells assessed using the XN-20 full blood count platform in patients with untreated viral infections i.e. HIV, HCV and HBV. The data from the analysis will be reviewed in conjunction with patient's demographic and clinical disease characteristics with the aim of detecting characteristic cell populations that can be used in the development of system flags for future studies.

Fever is one of the most common problems in pediatrics. Differentiating between bacterial infections, that require antibiotic therapy, and viral infections that resolve on their own is an important challenge for physicians. C-reactive protein (CRP) is a protein that increases in response to inflammation and its level is generally higher in bacterial infections compared to viral infections. it can be measured by a simple blood test, however its utility as a sole marker for bacterial infection is limited. The hypothesis of the study is that measuring CRP velocity, e.g the value of CRP divided by the hours since the fever started will improve the utility of CRP for the diagnosis of bacterial infections in children.

It is estimated that 350-400 million people worldwide are chronically infected with hepatitis B virus (HBV). Cirrhosis and hepatocellular carcinoma are major complications of chronic HBV infection and are responsible of about 500,000 deaths each year. Although some predictive factors of the outcome of chronic HBV infection were reported, it remains needed to more precisely determine the factors which are associated with the outcome in non-selected patients. Indeed, these factors should help to identify patients who are likely to have a better or worse evolution of their chronic HBV infection over time and thus, to adapt their clinical management and monitoring.Therefore, our purpose is to constitute a "real-life" cohort of non-selected patients to create a database of epidemiological, clinical, biological, virological and therapeutic parameters, in order to determine factors associated with the outcome of chronic HBV infection.
