Active clinical trials for "Severe Acute Respiratory Syndrome"

Ice swimming is an increasingly common phenomenon in Poland. It has been confirmed that it has a beneficial effect on health by increasing the natural non-specific immunity to infections. In the face of the current Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) pandemic causing Coronavirus Disease 2019 (COVID-19), researchers decided to use a survey to check the incidence of COVID-19 among Polish ice swimmers, as well as recent ailments. Then, the researchers will compare the obtained results with epidemiological data for Poland.Researchers will also investigate the relationship between susceptibility to SARS-CoV-2 infection and the blood group and Rh factor among ice swimmers.

Although several therapeutic agents have been suggested for the treatment of the disease caused by the Coronavirus of the year 2019 (COVID-19), no antiviral has yet demonstrated consistent efficacy. This is an observational study comparing Tenofovir-DF (disoproxil fumarate) (TDF) with Hydroxychloroquine (HCQ) in the treatment of hospitalized patients with COVID-19 with evidence of pulmonary compromise and with supplemental oxygen required.

This is a double-blind placebo controlled trial that seeks to evaluate the impact of melatonin and vitamin C on symptoms and outcomes of patients with COVID-19.

COVID-19 infection is overwhelming Italian healthcare. There is an urgent need for a solution to the lack of ICU beds and increasing deaths day after day. A recent retrospective Chinese paper (JAMA Intern Med, online March 13, 2020) showed impressive positive effect of methylprednisolone (MP) on survival of SARS-CoV-2 critically ill patients. Moreover, the Italian Infectious Disease leading institution guidelines for COVID-19 clinical management included as an option for patients with "incipient worsening of respiratory functions" methylprednisolone treatment at an approximate dose of 80mg. The main objective of this multi-centre observational trial is to analyse the association of low dose prolonged infusion of methylprednisolone (MP) for patients with severe acute respiratory syndrome with composite primary end-point (ICU referral, need for intubation, in-hospital death at day 28).

Purpose: To determine the number of asymptomatic individuals who have antibodies to SARS-CoV-2, the virus which causes COVID-19

Protocol summary Title A Prospective, randomized, adaptive phase II/III clinical trial, controlled, open-label, chemoprevention, 3-arms, parallel, multi-centred, to A Prospective, randomized, clinical trial, controlled, open-label, 3-arms, parallel, multi-centred, chemoprevention of COVID-19: Hydroxychloroquine Post Exposure Prophylaxis For COVID-19 Study Periods & Duration of Treatment Study Duration: 6 months Approval (IRB and regulatory bodies) 1 month Recruitment and follow-up: 3 months Analysis, report writing and submission of publications 1 month This study is a parallel study of one period with an expected duration of treatment (for each subject) of 28 days, Objectives To evaluate if hydroxychloroquine with the proposed dose can provide potent chemoprophylaxis against the development of COVID-19 positive patients in subjects who had primary exposure to COVID-19 positive patients. To measure the incidence of potential adverse drug reaction rates for giving hydroxychloroquine for prevention of COVID-19 amongst close contacts To provide early analysis of results and redefine sample size accordingly. identifying subjects most likely to benefit during the phase II and focusing recruitment efforts on them during phase III stopping one arm or the whole trial at an early stage for success or lack of efficacy based on phase II study results Design Prospective, Randomized, open-label, three-arm, parallel, adaptive phase II/III controlled study in which subjects will be randomly assigned in a 1:1:1 ratio as per the following: Arm-1: hydroxychloroquine 800mg (400mg twice daily) given orally on day 1, (loading dose) hydroxychloroquine. Then 400mg (200mg 2 tablets) on day 2,3, 4 and 5. Arm-2: hydroxychloroquine 400mg (200mg twice daily) Given orally first day (loading dose), then 200mg once daily on day 2,3, 4 and 5. Arm-3: No Intervention- SARS-CoV-2 surveillance Standard control measures in the country of interest such as self isolation, good personal hygiene and good nutrition.

This study is intended to address the association between vitamin D status and seroconversion to SARS-CoV-2 in healthy young adults. The primary aim of the study is to determine the rates of 'silent' seroconversion rates, consistent with asymptomatic transmission of SARS-CoV-2, in a young healthy adult population with a wide spread of vitamin D concentrations. The secondary aims of this study are to explore: Any effect of vitamin D status on symptomatic illness. The background 'point' prevalence and subsequent rate of increase in seropositivity for SARS-CoV-2 in healthy young adults. The individual reductions in seropositivity to SARS-CoV-2 over time, and changes in seropositivity in a defined young adult population over time. Where salivary Immunoglobulin A (IgA) may be used to provide an alternative/ complementary serological method The effect (if any) of vitamin D supplementation on seroconversion rates stratified by: i) level of baseline vitamin D 'deficiency/ insufficiency/ sufficiency' status; ii) extent of BMI-defined normal/overweight/obesity cut-offs and iii) gender.

The associated use of Ivermectin, aspirin, dexamethasone, and enoxaparin (in different combinations and doses) will reduce the impact of COVID infection 19, the need of admission to the intensive care unit, and mortality.

Evidence suggests coronavirus disease 2019 (COVID-19) is associated with an increased incidence of thromboembolic manifestations. Various guidelines on managing antithrombotics in COVID-19 either provided conflicting guidance or unclear recommendations for post-discharge thromboprophylaxis. The investigators aim to collect the current practices in India among physicians on antithrombotic therapy for hospitalised patients with COVID-19 and after discharge from the hospital.

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.
