Characterisation of the Immune Response to SARS-CoV-2 Infection / COVID-19 in Type 1 Diabetes

SARS-CoV2 InfectionDiabetes Mellitus1 more

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.

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.

SCREENING AND SEROEPIDEMIOLOGY OF SARS-CoV-2 INFECTION AT THE UNIVERSITY OF BARCELONA: A CROSS-SECTIONAL...

SARS-CoV-2 Infection

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.

Using Telemedicine to Optimize Teamwork and Infection Control of Critical and Highly-infectious...

Critical IllnessInfections4 more

Since 2000, various emerging infectious diseases have repeatedly caused serious impact on the health of the global population and the healthcare systems. With the growing international transportation and improving accessibility of the healthcare systems, hospitals have been inevitably the first sentinels dealing with emerging infectious diseases. The biological disasters, such as the Severe Acute Respiratory Syndrome (SARS) in 2003, the Middle East Respiratory Syndrome (MERS) outbreak in South Korean in 2015, and the Coronavirus disease 2019 (COVID-19) outbreak this year, challenged our vulnerable healthcare systems and caused great loss of lives. Regarding the ongoing global epidemics and possible community outbreaks of the COVID-19, the management of biological disasters for an overcrowded emergency department should be planned. In the early 2020, the emergency department used a double-triage and telemedicine method to treat non-critical patient with suspected COVID-19. This application reduced the exposure time of the first responders and reserve adequate interview quality. However, for the critical patients treated in the isolated resuscitation rooms, the unique environment limited the teamwork and communication for the resuscitation team. These factors might led to poorer quality of critical care. The investigators designed a telemedicine-teamwork model, which connected the isolation room, prepare room and nursing station by an video-conferencing system in the emergency department. This model try to break the barriers of space between the rooms and facilitate the teamwork communications between each unit. Besides, by providing a more efficient workflow, this model could lower the total exposure time for all workers in the contaminated area. This study was conducted to evaluate the benefits of the telemedicine-teamwork model and provide a practical, safe and effective alternative to critical care of the patients with suspected highly infectious diseases.

Pleural InfectionEmpyema3 more

The incidence of pleural infection is increasing worldwide since the last two decades. Antibiotics are one of the cornerstones of the treatment of this disease and must be associated to a correct evacuation of the pleural effusion. Data concerning the pleural diffusion of antibiotics currently used in community acquired pleural infection are scarce. The main objective of this study is to evaluate the pleural pharmacokinetic of amoxicillin and clavulanic acid in patients with a complicated pleural infection (patients who need a chest tube insertion).
