Active clinical trials for "Coronavirus Infections"

This treatment protocol is designed to provide convalescent plasma as a therapeutic option for patients diagnosed with and hospitalized for COVID-19 with symptoms ranging from mild to life-threatening.

An open access study that will define and collect digital measures of coughing in multiple populations and public spaces using various means of audio data collection.

The purpose of this study is to test over time immunity to SARS-CoV-2, a recently identified coronavirus responsible for the 2019 world-wide pneumonia outbreak known as COVID-19. Adults and children diagnosed with COVID-19 as well as controls without COVID-19 will be invited to participate in this study.

In December 2019, Coronavirus infection (COVID-19) was identified as causing serious respiratory infection in humans. Initially COVID-19 was propagated by infected symptomatic individuals; currently the disease is disseminated by asymptomatic COVID-19 positive subjects. The prevalence of asymptomatic COVID-19 individuals is unknown. Due its physiologic immune suppression, pregnancy is a vulnerable time for severe respiratory infections including COVID-19. Limited information is available regarding the impact of COVID-19 in pregnancy and the prevalence and demographic profile of asymptomatic pregnant women. Despite reports of 15-20% positive COVID-19 tests in women admitted to Labor and Delivery, professional obstetric medical societies still recommend not prioritizing testing of patients who are asymptomatic. In the USA, COVID-19 symptomatic patients come predominantly from lower income, Black and Latino communities. No data are available on the rate and demographic distribution of asymptomatic positive COVID-19 pregnant women. To minimize the risk of inadvertent exposure asymptomatic individuals, recently our institution started COVID-19 testing in all admitted pregnant women. The investigators expect to gain knowledge on the impact of COVID-19 in pregnant women especially if asymptomatic and compare to other respiratory infections.

This study is to evaluate the utility of the PCL Rapid Antigen Test for Coronavirus (COVID-19) in a real world clinical setting. The PCL test has completed laboratory validation and holds a European CE marking for in vitro diagnostic devices. These tests have been made available to South West Pathology Services as a donation in kind by iPP (Integrated Pathology Partnership). They have been widely used in South Korea. This study will test the practical delivery of the test in terms of time constraints and error rates. We will also compare the objective performance to the current standard diagnostic test for COVID-19 and against a proven serological antibody test when a suitable reference testing becomes available. We will recruit patients having a SARS CoV-2 PCR swab test and ask for consent to test them with the PCL antigen test in parallel. We aim to study 200 patients split across three sites; Musgrove Park Hospital, Basildon University Hospital and Southend University Hospital. The results will not be used to guide clinical decision making. Patients having a COVID PCR test will be asked to read the patient information sheet and asked if they would like to participate. The patients will be asked to have a second nasal/throat swab taken shortly after their swab for the PCR test. Written informed consent will be taken for whole blood or plasma left over from any routine clinical sample to be stored as anonymised samples for future testing once a reference test becomes available. We will report results of the onsite clinical diagnostic test and the PCL antigen test with the number of the kit used, and test date. Anonymised information about year of birth, gender and place of testing will be collected alongside date of onset, symptoms and immunodeficiency status or significant conditions.

Surfactant protein plays important role in innate immunity against respiratory viral infections. However, investigators have shown that the surfactant protein polymorphisms are associated with severity of various pulmonary diseases such as respiratory syncytial virus (RSV), tuberculosis, pediatric acute lung injury. COVID-19 virus gains entry through the respiratory system and responsible for death due to acute respiratory failure. There is a considerable heterogeneity in presentation of COVID-19 infection from asymptomatic patients to severe infection requiring intensive care and some may die. Considering reports of COVID-19 related deaths/severe disease in the same family, it is possible that genetics play an important role in severity of COVID-19 infection. Investigators propose to study the association of surfactant proteins in COVID-19 patients. Key Objectives: a) Characterize genetic markers within the surfactant protein genes in COVID-19 positive patients, b) To determine if there is a correlation between certain genetic markers and the severity of COVID-19 infection which may be used as a prognostic marker, c) To correlate genetic markers with immune studies.

Modulation of the renin angiotensin system by the chronic hepatitis C virus treatment either by (Daclatasvir and Sofosbuvir), (Daclatasvir and Sofosbuvir plus Ribavirin), or (Ribavirin and Interferon) protocols could give an explanation for the low incidence of COVID-19 among Egyptian population. Adding it may play a role in COVID 19 prophylaxis.

The reason the investigators want to do this research; Especially after Covid-19 infection, no research has been found on functional status in the long term. Therefore, in our study, the investigators aimed to evaluate exercise capacity, functional status, peripheral muscle strength, balance, anxiety and depression level, consciousness, work productivity, pain, fear of movement, and quality of life in patients with Covid-19 and to compare them with healthy individuals who have not had COVID-19.

Demographic, Clinical and laboratory data as well as outcome of total 202 COVID-19 patients who were Polymerase Chain Reaction (PCR) positive and admitted in Fatima memorial Hospital, Lahore, Pakistan, was collected during first and other waves. Data of First wave is from May 2020 to July 2020, second wave from early November to Mid December 2020 and third wave from Mid march to June 2021. Investigator analyzed the data on basis of Systemic immune inflammatory index (SII) as well hematological parameters of First Wave were compared to other waves of COVID-19.

A total of 300 healthy volunteers between the ages of 18 and 80 with no previous history of COVID-19 will be entered into the study and will receive IPV by injection on Day 1. Blood specimens collected pre-inoculation will be tested for cross-reactivity to poliovirus and SARS-CoV-2 by Western blot. An additional specimen will be collected on Day 28 post-inoculation and, likewise tested for cross-reactivity to poliovirus and SARS-CoV-2. The number of subjects with an immune response to SARS-CoV-2 antigens following inoculation with IPV will be summarized.
