Active clinical trials for "Severe Acute Respiratory Syndrome"

Countries that have not carried out universal mass vaccination against tuberculosis (BCG) have been shown to have higher incidence and death rates due to COVID-19 than countries with mass, long-term BCG immunization programmes. The aim of the study is to answer the following questions: Does BCG vaccination affect the course of COVID-19 (number of cases/deaths/severity of symptoms)? Will the course of COVID-19 be milder among subjects with a negative TB skin test (PPD RT 23 SSI) after an additional dose of BCG than in case of non-vaccinated subjects? Do people with a positive TB skin test have a milder course of COVID-19 infection than people with a negative test result? A multicenter, randomized, partially blinded, placebo-controlled study will be conducted in Rzeszow/Krakow/ Katowice/Warsaw on a group of 1000 volunteers, health care workers according to the following schedule: V 0-1: inclusion/informed consent/interview; V2: administration of TB skin test/anti-SARS-CoV-2 IgG test/serum banking*; V3: TB skin test (TST) interpretation and subjects' division into three groups: (I) positive TST - observation; (II) negative TST- BCG-10 vaccination; (III) negative TST - placebo. Division into groups II and III based on randomisation; V4: serum banking*. Parallel beginning from V3, weekly telephone monitoring participants' health status; In case of COVID-19 symptoms a nasopharyngeal swab to confirm SARS-CoV-2 infection + serum banking*. V5: 3 months after vaccination at the end of the study: history/anti-SARS-CoV-2 IgG test, serum banking*. Statistical analysis - comparison of the course of COVID-19 in groups: (I) with positive TST + observation, (II) with negative TST + BCG, (III) with negative TST + placebo - should demonstrate whether mass BCG vaccination has an impact on the incidence and course of COVID-19. * to measure the level of cytokines involved in cell-mediated immunity process

Respiratory infections such as colds, flu and pneumonia affect millions of people around the world every year. Most cases are mild, but some people become very unwell. Influenza ('flu') is one of the most common causes of lung infection. Seasonal flu affects between 10% and 46% of the population each year and causes around 12 deaths in every 100,000 people infected. In addition, both influenza and coronaviruses have caused pandemics in recent years, leading to severe disease in many people. Although flu vaccines are available, these need to change every year to overcome rapid changes in the virus and are not completely protective. This study aims to find and develop predictive tests to better understand how and when flu-like illness progresses to more severe disease. This may help to decide which people need to be admitted to hospital, and how their treatment needs to be increased or decreased during infection. The aim is to recruit 100 patients admitted to hospital due to a respiratory infection. It is voluntary to take part and participants can choose to withdraw at any time. The study will involve some blood and nose samples. This will be done on Day 0, Day 2 and Discharge from hospital, and an out-patient follow-up visit on Day 28. The data will be used to develop novel diagnostic tools to assist in rational treatment decisions that will benefit both individual patients and resource allocation. It will also establish research preparedness for upcoming pandemics.

This is a cohort study, in which the investigators will follow-up 650 health care workers (HCW) and a selection of their households (of COVID positive and COVID negative HCW) at baseline and in three follow-up surveys, with 4 to 6 weeks of time interval. The investigators will select HCW from different wards and different health care structures in 5 communes of Kinshasa. Additionally, in the first survey among HCW, the investigators will test with different diagnostic platform to evaluate the performance of serological tests in the African setting and the effect of malaria infection on the performance of tests. An amendment is added to the protocol, stating an additional 2 surveys in april/June 2021 and October/November 2021 to evaluate impact of second wave and of vaccination campaign.

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 study explores the actual situation of communication during the Coronavirus disease 2019 (COVID-19) pandemic in the South Asia and Middle East region. The purpose is to assess the effect of the limited visitor policy during the COVID-19 pandemic, on the pattern of interaction of critically ill patients to their kin/ guardian and doctor-family members communication. Primary objective of this study are as follows: Explore the changes in communication pattern with limited contact during the COVID-19 pandemic. Assess the methods of informed consent in Intensive care units (ICUs) during the same period

The Coronavirus Disease of 2019 (COVID-19) pandemic has caused an international healthcare crisis and produced a large healthcare burden. Diabetes mellitus is a common disease that can be controlled via pharmacologic agents; however, many patients have poor glycemic control, leading to disease-related complications. Diabetes mellitus has been reported in the literature to be associated with increasing morbidity and mortality in COVID-19 patients, and some hypothesize that this is due to insulin dysregulation propagating a pro-inflammatory state. The investigators aim to contribute to the growing body of literature that assesses the associations between glucose homeostasis and COVID-19 disease severity and mortality.

As a direct consequence of the COVID-19 pandemic, it is assumed that the number of patients with COVID-19-related disabilities will increase significantly. Patients with mild, severe, and critical forms of the disease show long-term sequelae in different systems (respiratory, muscular, psychological, cognitive etc.). Persistent dyspnea is a frequently described symptom after the acute phase of the disease. Coupled with reduced oxygen saturation, an increased risk of developing lung fibrosis has been observed. Specialized rehabilitation medicine (e.g. pulmonary rehabilitation) might counteract these long-term consequences and therefore seems to be a promising approach to treat long-term COVID-19 consequences. Further, there is scarce evidence about COVID-19 specific rehabilitation contents. It was suggested to use treatment regimes in analogy to patients with idiopathic pulmonary fibrosis. There is evidence that pulmonary rehabilitation improves physical performance, quality of life and reduces anxiety and depression symptoms in patients with idiopathic pulmonary fibrosis and other chronic respiratory diseases. Since impairments related to idiopathic pulmonary fibrosis also play an important role in COVID-19, the aim of this study is to evaluate the short and medium-term effects of a standardized 3-week pulmonary rehabilitation program. The results will be analyzed within the two cohorts (mild/moderate and severe/critical COVID 19) as well as between the two cohorts for the primary outcome. Furthermore, the effects of pulmonary rehabilitation will be compared with a retrospective cohort of idiopathic pulmonary fibrosis.

The BBV152 vaccine is being developed to prevent COVID-19, the disease resulting from Severe Acute Respiratory Syndrome coronavirus (SARS-CoV-2) infection. The study is designed to primarily evaluate the efficacy, safety, and immunogenicity of BBV152 to prevent COVID-19 for up to 1 year after the second dose of BBV152.

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.

Effectiveness of the use of Tenofovir/Emtricitabine in addition to personal protective equipment for the prevention of the transmission of SARS-COV-2 to health care personnel. A Randomized Clinical Trial. This is an experimental study whose aim is to evaluate the effectiveness of a drug to prevent infection with the virus that causes COVID-19 (SARS-CoV-2), in health care workers. The drug under study is Tenofovir /Emtricitabine, a well-known antiretroviral, which is safe and is used as prophylaxis and treatment for HIV and other viral infections such as Hepatitis. Several laboratory-based studies indicate that this drug has the potential to inhibit SARS-CoV-2 replication. In addition, one study in HIV infected persons found that those taking Tenofovir /Emtricitabine tended to have a lower occurrence of COVID-19. In this study, we will compare the occurrence of infection with SARS-CoV-2/ COVID19 in health care workers between those assigned to an intervention group and those assigned to a control group. The intervention group will receive Tenofovir /Emtricitabine during 60 days in addition to the use of personal protective equipment (PPE), and the control group will receive a placebo during 60 days in addition to the use of personal protective equipment (PPE). The study will recruit 950 health professionals above 18 and less than 70 years, working in the emergency room, COVID wards and intensive care units of seven hospitals in Colombia. To make the comparison groups very similar, the participants will be assigned through a random mechanism to either the intervention (475), or the control (475) groups. In order to prevent biases in the evaluation of the results, neither the participants nor the clinical investigators, data managers, analysts and support personnel will know which intervention the participants are receiving. To determine the occurrence of infection with the virus the study will use both molecular tests that detect the presence of viral genes in respiratory secretions, and serological tests that detect the response of the immune system to the virus. The study will evaluate also the safety of this drug determining the occurrence of adverse events.
