Active clinical trials for "Severe Acute Respiratory Syndrome"

The study objective is to investigate the diagnostic value and consistency of chest CT as compared with comparison to RT-PCR assay in COVID-19 in patients which were stratified for hospital admission.

Acute respiratory failure (ARF) is a common condition and a common reason for urgent medical consultation. Assessing the extent of respiratory impairment is important to improve the management of patients with ARF. When Acute respiratory failure is caused by pathology of the pulmonary parenchyma, quantification of pulmonary radiographic involvement may be a component of the initial assessment of severity. This radiographic quantification would only be usable in clinical routine if it can be automated and provide a real-time result. The objective of this work is to assess the feasibility of an automated technique for quantifying radiological lung damage in situations of known or potential ARF.

We have herein analysed the patients admitted to our Department that underwent serologic tests for SARS-CoV-2 either by Ab or RT PCR, to estimate the prevalence of COVID-19 in the setting of a non-dedicated COVID-19 hospital and in a low CoV-2 incidence area, and to evaluate if security measures are necessary for this context.

The oral cavity is particularly susceptible to viral infection with several viruses such as herpes simplex virus, cytomegalovirus and Zika virus because of its structures, especially salivary glands and soft tissues Moreover, oral mucosa can be affected by secondary pathological process of a bacterial or fungal nature due to viral immunosuppression. The oral cavity could be considered a "biological barometer" of both viral infection and viral immunosuppression advancement .

Coronavirus disease 2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Lung failure is the main cause of death related to COVID-19 infection. The main objective of this study is to assess infection of SARS-CoV-2 and how quality of life is affected in adult volunteers in Lake County, Illinois. Volunteers will be recruited through digital advertisements and participants will be required to fill an online questionnaire. Upon consent, participants will be required to provide nasal swab and blood sample. Approximately 1250 adult volunteers living or working in Lake County, IL will be enrolled. Participants will be followed for approximately 9 months and will be required to provide nasal swab and blood samples every 3 months and complete questionnaires every 2 weeks. There may be higher treatment burden for participants in this trial. Participants will be monitored by medical assessments, blood tests and questionnaires.

There is little information on the characteristics of airborne severe acute respiratory syndrome coronavirus containing aerosols, their concentration, or their infectivity.The aim was to determine airborne severe acute respiratory syndrome coronavirus transmission, their infectivity in different areas such as patient's room and in medical staff área.

An initial retrospective epidemiological investigation was conducted in a city north of France after the diagnosis of the first case of COVID-19 on February 2020. Sero-epidemiological studies were conducted in this town by the Institut Pasteur in early 2020 among families, teachers and non-teaching staff of the high and elementary schools. The goal of this new project is to better characterize the specific immunity generated by the infection within this community. The specific immune response to the SARS-CoV-2 virus will be followed for a period of 2 years from the initial circulation of the virus, within a large cohort of participants covering all age groups from 5 years-old onwards. The study will focus on systemic humoral and cell responses, immunity of the nasopharyngeal mucosa and the humoral response present in saliva. Follow-up of participants in this cohort and monitoring of the virus circulation within this community would help to determine the protective character against re-infection of the natural immunity generated by SARS-CoV-2.

Lung ultrasound has been used to help diagnose COVID-19 as an alternative to CT scanning and chest X-ray. CT scanning is onerous and there are difficulties taking critically unwell patients there as well as decontamination issues. Chest X-ray misses up to 40% of COVID diagnoses. Although lung ultrasound can diagnose, the investigators do not know how long these lung ultrasound changes last. The investigators would like to follow up patients to characterise the pattern of changes and how long they last. This is particularly important given a potential second surge of COVID-19 is looming and the investigators would like to know if lung ultrasound changes are new or old in patients presenting during this second wave and in the future.

This QI project seeks to evaluate the relative test sample acquisition throughput, personal protective equipment utilization, and relative operational costs of provider-administered COVID-19 (SARS-CoV-2) nasal samples with and with the use of HEPA-filtered, positive pressure isolation booths.

This study is a community hospital-based study that will enhance information being obtained in similar studies taking place in France, Denmark, and China. These studies are designed to assess risk of healthcare workers during outbreaks of Coronavirus 2019 (COVID-19) also known as sudden acute respiratory syndrome-coronavirus-2 (SARS-CoV-2). This will be a prospective, single-center observational study involving human subjects. IgG (Immunoglobulin G) antibody will be tested in the serum of physicians working at Advocate Lutheran General Hospital (ALGH). IgG antibodies are the antibodies that form in response to viral or bacterial infections and typically reflect protection against said infection. To date, there have been no studies confirming that IgG antibody formation confers immunity, but studies are ongoing. Furthermore, data is lacking showing conclusive persistence of (possibly protective) antibodies over time. Attending physicians on the medical staff, fellow physicians, and house staff residents who worked at ALGH from March 1st, 2020 and on, will be eligible for the study. Testing will involve a venipuncture to obtain approximately 3mL of blood to be sent to ACL Laboratories for SARS-CoV-2 IgG testing. For physician subjects, this will be performed on four separate occasions, once at the onset of the study, a second test 3 months after the first test, a third test 6 months from the time of the first test, and a fourth and final test 12 months after the initial test. Two household members (defined below), one-time testing will occur within 2 weeks of the physician subject testing positive. All testing will be performed in a two-week window. All physician subjects will be tested at a centralized site that is only serving these subjects, by appointment. We will be offloading testing for household members to one localized commercial ACL site on the ALGH campus at the Center for Advanced Care. The household member testing will be extended to an additional two-week period after the two week window in which physicians are tested for a total of four weeks maximum. One-time testing for IgG antibodies to COVID-19 will be offered to a maximum of two household members, as defined as, any person over the age of 18 years old who has lived at home with the physician, who has tested positive for IgG antibodies, for at least 2 weeks in total duration since March 1st, 2020. The physician will be permitted to choose who gets tested, and the chosen adult subject will provide their independent consent to be tested.
