Active clinical trials for "COVID-19"

Initial case reports and cohort studies have described many clinical characteristics of patients with coronavirus disease 2019 (COVID-19), an emerging infectious disorder caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). In early COVID-19 studies, some evidence has been provided that electrolyte disorders may also be present upon patients' presentation, including sodium, potassium, chloride and calcium abnormalities the aim of the study is Identification of elements that affect COVID-19 pathology to improve survival and decrease mortality rate.

Several studies have suggested a potential clinical benefit of controlling hyper inflammation triggered by SARS-CoV-2/COVID-19. Blood purification, the removal of excessive proinflammatory mediators may control disease progression and support clinical recovery. For this purpose, COVID-19 patients might benefit from treatment with AN69ST hemofilter based extracorporeal blood purification.

A multi-centre, observational cohort study will be carried out in consecutive patients operated on for urgent digestive pathology. Two cohorts will be defined: the 'pandemic' cohort, which will include all patients [COVID-19-positive or negative] operated on for emergency digestive pathology during the months of March to June 2020; and the control cohort, which will include all patients operated on for emergency digestive pathology during the months of March to June 2019. Information will be gathered on demographic characteristics, clinical and analytical parameters, scores on the usual risk scales for quality management in a General Surgery service (POSSUM, P-POSSUM and LUCENTUM scores), prognostic factors applicable to all patients, specific factors for patients infected with SARS-CoV-2, complications and postoperative mortality (at 30 and 90 postoperative days). In the pandemic cohort it will be detailed whether or not the patient was infected with SARS-CoV-2. The main objective will be to determine the incidence of postoperative complications and mortality. This variable will be analysed in the "full analysis set" population. Secondary objective will be to develop a specific postoperative risk propensity model for SARS-CoV-2 infected patients.

The goal of the study is to assess autonomic nervous system and cardiovascular controll during orthostatic challenge in 90 patients recovered from COVID-19 and devided into three groups depend on severity of the morbidity.

There is evidence that CV-19 is associated with joint symptoms, but there are no specific data on the temporomandibular joint (TMJ). It is also known that the systemic health status can impact the immune system. Given all this, this study aimed to investigate the effect of CV-19 and systemic health status, as determined by the American Society of Anesthesiologists (ASA) Physical Status Classification System 12, on TMJ in patients with TMJ complaints using the DC/TMD scale.

Observational program, double-blind, placebo-controlled to study the preventive efficacy of the BiVac polio (Oral polio vaccine, divalent, live attenuated of types 1 and 3 vaccine against the incidence of acute respiratory infections, including COVID-19

The primary objective of the study is to evaluable the safety and to demonstrate the immunogenicity of heterologous prime-boost (mRNA-1273, MVC-COV1901), compared to homologous prime-boost (mRNA-1273), with an interval of 8-12 weeks, This study also assesses the safety and tolerability of the study intervention and explores the immunogenicity by the antigen-specific immunoglobulin, the immunogenicity against the VoCs, the antigen specific cellular immune response, as well as the potential efficacy of study intervention in preventing COVID-19.

Evaluation of the efficacy of the AstrazenicaCovid 19 vaccine to develop IgG antibody and its level based on th12 weeks program. Also to follow the changes of markers of coagulation (D-dimer) after vaccination compared to the basic level. A cardiology consultant will follow D-Dimer results to be managed properly if there is a need. As it is expected to receive Sinopharm vaccine there will be comparison between results of the two types of vaccine. To our knowledge this will be the first study done on Egyptian population.

This study is a randomized, double-blinded, and placebo controlled phase Ⅱ clinical trial of the SARS-CoV-2 inactivated vaccine to evaluate the safety and immunogenicity of the experimental vaccine in healthy population aged 3 to 17 years.

This is an observational, non-interventional, prospective cohort study designed to collect clinical information and specimens to evaluate the immune responses from pregnant individuals and postpartum individuals and their infants following maternal receipt of licensed or Emergency Use Authorization (EUA) severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines.
