NCT06097429

Brief Summary

Context: Hypercoagulable state associated with COVID-19 is one of the pathologic events that noticed in different waves of COVID-19 pandemics and leads to serious consequences in mortality and morbidity Aim: To evaluate platelet aggregation using light-transmission aggregometry and adenosine diphosphate (ADP) as an agonist in COVID-19 patients. Settings and design: This was prospective cross-sectional study. Patients and methods: Seventy-five individuals were enrolled in this study and divided into two groups, 50 patients with PCR-positive COVID-19 as study group and 25 apparently healthy individual as a control group. All individuals were subjected to full clinical evaluation, CT-chest, laboratory investigations: CBC, INR, LDH, CRP, serum ferritin and platelet aggregation evaluation using light-transmission aggregometry and adenosine diphosphate (ADP) as an agonist

Outcome Measures

Primary Outcomes (1)

  • Mortality rate.

    recording from any mortality from the study and the control group

    day 0 to day 30

Secondary Outcomes (3)

  • Developing new thromboembolic event as arterial or venous thrombosis

    day 0 to day 30

  • Need to invasive mechanical ventilation (MV)

    day 0 to day 30

  • Length of hospital stay (days)

    day 0 to day 30

Study Arms (2)

study group

COVID-19 confirmed cases with positive PCR test in the first week of diagnosis

Diagnostic Test: blood sample for platelet aggregation

control group

healthy volunteers, persons with no history nor symptoms suggestive of COVID-19 with negative COVID -19 PCR test and no CT Chest changes suggestive of COVID-19 infection.

Diagnostic Test: blood sample for platelet aggregation

Study Population

Study group: COVID-19 confirmed cases with positive PCR test in the first week of diagnosis with COVID-19 CT changes with any severity grade according to WHO, (2020) Control group: healthy volunteers, persons with no history nor symptoms suggestive of COVID-19 with negative COVID -19 PCR test and no CT Chest changes suggestive of COVID-19 infection. They were also matched with the study group in demographic variables and comorbidities.

You may qualify if:

  • Age ≥ 18 years old.

You may not qualify if:

  • Patients with thrombocytopenia and thrombocytosis defined as platelet count less than 100,000/ µL, count more than 450,000 / µL respectively
  • Patients with hematocrit abnormalities as less than 34% or greater than 55%
  • Patients with disseminated intravascular coagulation (DIC)
  • Active malignancy
  • Liver disease as such chronic hepatitis, cirrhosis or liver cell failure.
  • Any hematological disorders as hemophilia or thalassemia.
  • Patients on invasive mechanical ventilation as endotracheal intubation and mechanical ventilation itself are factors for having a higher mean platelet volume (MPV) which means that platelets are larger than average which are more adhesive and likely to aggregate in vitro. Patients receiving aspirin, non-steroidal anti-inflammatory drugs, antiplatelet drugs or any other medications that can influence platelet function (14 days prior to blood sample collection)
