On April 20, blood analyses revealed hemoglobin 117 g/l, PT-INR 2.15, and a slight alteration of liver function with AST 55 U/l (normal range: 5-32). The temporal relationship between COVID-19 onset and PT-INR elevation in a patient whose PT-INR values were stable in the 18 months before the hospitalization supports the hypothesis that this infection may impact on the coagulative pattern not only pro-thrombotically [4, 5] but also by increasing hemorrhagic risk. This confirms that special attention should be paid to COVID-19 patients under long-term anticoagulation with vitamin K antagonist and a shift to heparin treatment until illness resolution may be a safe option in these individuals [7] . ./cache/cord-284785-mkjogy6h.txt ./txt/cord-284785-mkjogy6h.txt
