Active clinical trials for "Infections"

While many people with COVID-19 suffer from respiratory disease, there is growing evidence that the virus also affects other organs. The purpose of this study is to better understand the effects of COVID-19 on the lungs and other organs. The study investigators have developed new techniques in Magnetic Resonance Imaging (MRI) to scan the lungs, heart, brain and liver. The study investigators hope to learn more about how the virus causes inflammation in these organs and how this inflammation changes over time as people recover from COVID-19 illness. The study aims to enroll 228 people in Alberta. Participants will undergo one or more MRI scans and have blood testing at one or more time points to assess for inflammation, kidney function, liver function and possible heart injury. Participants will also undergo testing to assess sense of smell, cognition (thinking and memory), spirometry (breathing test for lung function) and and exercise tolerance (walk test). The study investigators hope this study will help us learn more about the long-term risks of COVID-19 disease.

This study seeks to identify and test host RNA expression profiles as markers for infections in young infants. Preliminary studies have shown high sensitivity and specificity for the discrimination of bacterial from non-bacterial infections in children, but the method has only been investigated in a limited number of young infants. The study aims to include 65 young infants with serious bacterial infections. The samples will be analysed by RNA sequencing. New diagnostic tools may help reduce unnecessary antibiotic treatment, antibiotic resistance, side-effects, hospitalisation and invasive procedures.

This is a prospective cohort study evaluating acceptability, feasibility, and effectiveness of integrating HIV pre-exposure prophylaxis (PrEP) into a sexually transmitted infection (STI) clinic alongside assisted partner notification and etiologic STI testing in Lilongwe, Malawi.

Emerging clinical details of the current SARS-CoV-2 pandemic have illustrated that there are multiple clinical presentations and outcomes of this viral infection. People with an infection have been reported to have a spectrum of disease from severe acute respiratory distress requiring ventilation, to mild respiratory or gastrointestinal symptoms and asymptomatic presentations. The SARS-CoV-2 pandemic has been accompanied with a substantial increase in the number of individuals presenting with new onset type 1 diabetes [1]. Most individuals presenting with type 1 diabetes since the start of the COVID-19 pandemic are SARS-CoV-2 antibody positive. These findings suggest that SARS-CoV-2 infection can cause type 1 diabetes. Investigators have identified that many individuals presenting with type 1 diabetes since the start of the COVID-19 pandemic are SARS-CoV-2 positive by swab or blood test. Researchers have also observed that T cells in patients who have had COVID recognise some of the peptides in the pancreatic islet cells, which are responsible for production of insulin. These findings suggest that SARS-CoV-2 infection may be associated with new onset of type 1 diabetes. The aim of this project is to understand the host immune response to infection with SARS-CoV-2 over time in convalescent newly diagnosed patients with type 1 diabetes, including acquired immune responses, gene expression profiling in peripheral blood and to identify host genetic variants associated with disease progressions or severity. Participants will have Type 1 diabetes and will have had a diagnosis of COVID-19 (confirmed by a positive nasopharyngeal swab PCR test and/or SARS-CoV-2 antibody test) and have recovered from COVID-19. Samples will be processed and analysed to explore the molecular mechanisms by which SARS-CoV-2 infection might precipitate immune attack on insulin-producing cells resulting in autoimmune diabetes.

This retrospective study will evaluate characteristics, vaccine utilization and outcomes among subjects with immunocompromising conditions that received COVID-19 vaccination.

Clinical trials of prevention modalities for Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection and coronavirus disease (COVID-19) and pneumonia are underway under separate protocol(s) for close contacts (i.e., household contacts, [e.g.,3502]) of infectious (index) individuals (3502-01). Characterizing the index individuals within households will ascertain the risk of exposure for the contact participant. These data will be used to strengthen the precision of efficacy estimates. This ancillary observational study will assess the cofactors for infectiousness among index individuals whose close contacts are enrolled in COVID-19 prevention clinical trials. Additionally, this study will assess post-acute sequelae of SARS-CoV-2 infection in index individuals that are more than two weeks past their initial diagnosis.

An outbreak of Corona virus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-coV-2) occurred in Wuhan city, Hubei province, China in December 2019. Pulmonary health has been the main focus of studies of COVID-19, current articles show that cutaneous signs appear in COVID-19 patients, their identification may be vital to early diagnosis and lead to possible better prognosis in COVID-19 patients

The primary objective of this study is to generate evidence demonstrating the domain specification (via modern psychometric methods), reliability, validity, and responsiveness (within-subject meaningful change) of the Patient-Reported Outcome (PRO) endpoints.

BACKGROUND: On January 7, 2020, the Chinese authorities identified as the agent responsible for the cases of atypical pneumonia of unknown etiology a new type of virus of the Coronaviridae family that has subsequently been named SARS-CoV-2, whose genetic sequence was shared by Chinese authorities on January 12 (taxonomy ID: 2697049). On January 30, 2020, the director general of the World Health Organization (WHO), following the advice of the Emergency Committee convened in accordance with the International Health Regulations (2005), declared that the COVID-19 outbreak started in Wuhan, China in December 2019, being a public health emergency of international concern. On March 11, the WHO declared the global SARS-CoV-2 pandemic. So far, in the absence of effective vaccines or antiviral drugs, efforts have focused on identifying cases and their contacts. Both the cases and their contacts are isolated for about 14 days with the intention of minimizing the spread of this infection and avoiding an increase in the number of affected. At the time of writing this new version of the protocol, we are immersed in the second wave of the COVID-19 pandemic. The projections of the natural history of the disease and the estimates of possible infections by SARS-CoV-2, carried out at the end of the first wave, made it possible to determine the feasibility of this second wave with the onset of cold from the autumn. Given this scenario, the University of Barcelona, together with the Gerencia Territorial del Área Metropolitana Sud, has planned to carry out, a study of seroprevalence and screnning of SARS-CoV-2 in the population of Universidad de Barcelona users. The results of this study will help to make preventive decisions in the face of SARS-CoV-2 infection at the UB, in relation to its teaching and administrative activities. In addition, this cross-sectional study can serve as the base study for a future follow-up study. HYPOTHESIS: The incidence of SARS-CoV-2 infection in the group of students and workers at the University of Barcelona is similar to the incidence in the general population. MAIN OBJECTIVE: Estimate the incidence of SARS-CoV-2 infection in the UB community. Estimate the SARS-CoV-2 seroprevalence infection in the UB community.

This study aims to provide some insight into the variation of SD-D protein levels in patients with Covid-19 (-) pneumonia, Covid-19 (+) pneumonia, and CT negative Covid-19 infection in comparison to the normal population through a larger number of cases. Objective of the study is to determine the serum surfactant protein D (SP-D) levels in Covid-19 pneumonia infection.
