Filter by:None of the vaccines approved, or in clinical trials, have so far been tested on transplanted patients. If they produce an immune response to the Spike protein of SARS-CoV-2 it is unknown how long the protective immunity will last. Not all immune responses are equal. The investigators will quantify immune cell subsets with flow and mass cytometry analyses to describe the phenotype of responding immune cells, including specific T cells. If not already established, patient human Leukocyte antigen (HLA) genotypes will be typed. In order to compare the immune responses with healthy individuals a control group of hospital employees will be included and sampled before and after vaccination according to the same time schedules as the kidney transplanted patients.
Stopping the SARS-CoV2 spread is essential to control the pandemic cause by this virus. A great effort is being made to carry out surveillance, case detection and contact control protocols in order to detect and isolate those contagious subjects. Since both symptomatic and asymptomatic subjects can be contagious, a surveillance system based on the presence of symptoms is not enough, requiring to perform diagnostic tests in a large number of subjects, such as asymptomatic contacts or high-prevalence populations, and repeatedly. Moreover, the speed in obtaining results is crucial in order not to delay the isolations of positive subjects. The polymerase chain reaction (PCR) is an expensive test which requires specialized equipment and personnel with a delay in results of 24-48 hours. In addition, its high sensitivity can mean that subjects without infective capacity have a positive result. In contrast, antigen detection tests (ADTs) are cheap and easy to perform, having a result in few minutes. They have shown high sensitivity and specificity in symptomatic subjects, specially in the first week of symptoms when the viral load is high. This could be very useful for the study of asymptomatic contacts to detect those with potential contagiousness quick, easily and cheaply. However, there is no evidence to support the use of ADTs in this group of subjects. For this reason, the investigators propose to carry out a study to compare the diagnostic efficacy of ADTs versus PCR in the group of subjects considered to be close contacts of SARS-Cov2 positive patients in the health area of Cáceres.
Point of care testing is urgently required to enable the immediate detection of SARS-CoV-2 infection to allow effective transmission prevention precautions to succeed.
Nursing homes have long faced special challenges in implementing effective infection prevention programs, including limited resources and diagnostic challenges in a frail functionally disabled long-stay population. Advancing our understanding of the transmission of SARS-CoV-2 within these facilities for vulnerable populations deserves urgent and further investigation. Environmental contamination with SARS-CoV-2 that is reported in limited studies highlights the potential importance of transmission between patients, their environment, and healthcare providers via direct and indirect contact. This study seeks to characterize the epidemiology of SARS-CoV- 2 in the NH patient room environment over time and the risk of transmission to near and far environments, with the explicit intent of developing integrated, simple COVID-19 infection prevention strategies that can be reported to and implemented throughout other nursing homes and long-term care facilities.
Analysing ths spread of COVID-19 epidemics in a timely manner is key to implementing public health control strategies. The investigators propose to analyse a large set of laboratory SARS-CoV-2 RT-PCR data to explore potential links between Ct values and epidemic parameters.
The ongoing pandemic of SARS CoV-2 virus is calling for effective preventive and theraputic interventions. Vitamin D has been shown to play immunemodulatory functions in human. Low vitamin D levels have been linked to increased susciptability to infections especially the acute respiratory infections. This randomised controlled study aims to explore the effect of vitamin D administration on the outcome of SARS- CoV2 virus
As part of the Coronavirus Infectious Disease 2019 (COVID19) pandemic, the hospital care system is facing a major strain. Patients with SARS-Cov2 (severe acute respiratory syndrome coronavirus 2 ) infection can worsen very quickly, possibly presenting, within hours, severe respiratory failure requiring urgent specialized care. Therefore, it is essential to develop emergency assessment tools to assess relevant criteria to decide which patients must be kept under hospital monitoring and which patients can be treated on outpatient care. The aim of this study is to assess the efficacy of STST in the decision to hospitalize patients consulting emergency department for a SARS-Cov2 infection. The investigators wish to show that the addition of this test to the usual hospitalization criteria reduces the proportion of patients hospitalized 48 hours after their first visit to the emergency department.
This is a prospective, placebo controlled, individually randomized controlled phase III trial in Primary Care, assessing the efficacy of antivirals, i.e. camostat and molnupiravir, in accelerating recovery in Covid-19 patients.
Acute treatment of COVID-ARDS with direct topical lung instilled T3 therapy for patients on mechanical ventilation.
The aim of this study is to compare the SARS-CoV-2 detection rate using either a Saliva, oropharyngeal swabs or nasopharyngeal swab method for specimen collection.
