BACKGROUND:In recent outbreak of COVID-19 infection,the risk of thrombosis should be concerned.We observed dynamic changes of D-Dimer level,C-Reactive Protein(CRP) level and Venous Thromboembolism risk assessment score(VTE score) during active disease.We included patients of conrmed covid-19 patients who were RT-PCR positive and patients of community acquired pneumonia(CAP) who were conrmed by CT-SCAN ndings.We observed correlation of D-dimer level with both CRP level & VTE score. METHOD:We examined the clinical laboratory result of 50 patients with conrmed COVID-19 positive patients and 50 patients with community acquired pneumonia(CAP).We analysed D-dimer level of this patients by Automated Coagulometer-STAGO in our hematological laboratory and CRP level by latex method.We use pauda prediction score to identify patients at high risk for venous thrombo embolism.We observed D-dimer level of all patients with their correlation to CRP level & VTE score.S RESULT:On admission,Both COVID-19 and CAP patients,D-dimer level were increased,more increased in COVID-19 patient compare to CAP patient. D-dimer level were related to inammatory marker,mainly with CRP level.There was low correlation between VTE score & Ddimer levels weakened the role of D-dimer in the prediction of thrombosis. CONCLUSION:Elevated baseline D-dimer levels are associated with inammation but not with VTE score in COVID patients,So we can't judge whether anticoagulation is needed only according to D-dimer levels. Abnormal D-dimer level with inammatory factors suggest that anticoagulant therapy might be needed.
