Covid19 Clinical Trial - Effect of COVID-19 on Platelet Aggregation

Status Completed

Clinical Trial Summary

This is a mechanistic, observational, prospective, case and control study, to compare platelet aggregation, analyzed by Multiplate-ADP, in hospitalized patients diagnosed with COVID-19 versus healthy controls. Thus will be included 60 patients who present with respiratory symptoms within 72 hours of hospitalization and confirmation of the diagnosis of COVID-19 by laboratory method (RT -PCR and / or positive serology for SARS-CoV-2 - COVID group); this group will be compared to 60 healthy individuals (asymptomatic and with negative SARS-CoV-2 serology), matched by sex and age to the previous group.

Clinical Trial Description

There is strong evidence that SARS-CoV-2 infection is associated with atherothrombotic phenomena. However, platelet activity in COVID-19 has not yet been studied. Thus, the main objective of this project is to evaluate platelet aggregation by the Multiplate-ADP method in hospitalized patients diagnosed with COVID-19, in comparison with the platelet aggregation evaluated by the same method in healthy controls. Secondary objectives include the assessment of parameters related to coagulation, inflammation, and clinical outcome variables. This is a mechanistic, observational, prospective, case and control study, which will include 60 patients who present with respiratory symptoms within 72 hours of hospitalization and confirmation of the diagnosis of COVID-19 by laboratory method (RT -PCR and / or positive serology for SARS-CoV-2 - COVID group); this group will be compared to 60 healthy individuals (asymptomatic and with negative SARS-CoV-2 serology), matched by sex and age to the previous group. ;
