Aminotransferases disorders associated with venous thromboembolic events in patients infected with COVID-19.

INTRODUCTION AND OBJECTIVES: Since the outbreak of the COVID-19 pandemic, increasing evidence suggests that infected patients present a high incidence of venous thromboembolic (VTE) events and elevated aminotransferases (AT).The objective of this work was to evaluate the incidence of aminotransferases disorders in patients infected with COVID-19 and to manage the VTE events associated with elevated AT. PATIENTS OR MATERIALS AND METHODS: We report a retrospective study of 46 patients admitted for COVID-19 infection. Venous duplex ultrasound of lower limbs was performed in all patients at Day 0 and Day 5. All patients had antithrombotic-prophylaxis upon admission using low molecular weight heparin with Enoxaparin. Demographics, comorbidities and laboratory parameters were collected and analyzed. RESULTS: Elevated AT were reported in 28 patients (61%). 10 had acute VTE events of which eight (17.4%) had aminotransferases disorders. They had been treated with curative Enoxaparin. After a follow-up of 15 and/or 30 days, six of them were controlled, and treated with direct oral anticoagulant (DOACs) after normalization of aminotransferases. CONCLUSIONS: The incidence of aminotransferases disorders associated with acute VTE events in patients infected with COVID-19 is significant. The use of DOACs appear pertinent in these patients. Monitoring of the liver balance should therefore be considered at a distance from the acute episode in the perspective of DOACs relay.

Systematic duplex ultrasound screening in conventional units for COVID-19 patients with follow-up of 5 days.

OBJECTIVE: COVID-19 patients may develop coagulopathy, which is associated with poor prognosis and high risk of thrombosis. The main objective of this work was to evaluate the prevalence of deep venous thrombosis of lower limbs (DVT) through ultrasonography in patients infected with COVID-19 admitted to conventional units at our hospital with 5 days of monitoring. The secondary objective was to determine if D-dimer levels, body mass index, and C-reactive protein were associated with DVT. METHODS: A total of 72 patients, with a mean age of 65 ± 12.3 years, infected with COVID-19 were admitted to three conventional units at our institution; 28 patients were women. A COVID-19 diagnosis was made by a transcriptase polymerase chain reaction by means of nasopharyngeal swab or by chest computer tomography without iodine contrast media. Demographics, comorbidities, and laboratory parameters were collected. A preventive anticoagulation treatment was established on admission with low-molecular-weight heparin. A complete venous duplex ultrasound (DU) test of lower limbs was performed on day (D) 0 and D5. A pulmonary computer tomography angiogram with iodine contrast media was required when pulmonary embolism was suspected. RESULTS: On D0, the DU showed acute DVT in seven patients (9.75%). A pulmonary computer tomography angiogram was performed in 12 patients (16.65%), 3 (25%) of whom had an acute pulmonary embolism. On D0, acute DVT was not significantly associated with C-reactive protein (mean 101 ± 98.6 in the group without DVT vs 67.6 ± 58.4 mg/L, P = .43) or body mass index (27.7 ± 5.04 vs 28.1 ± 2.65 kg/m2, P = .54). However, we found a significant association between acute DVT and D-dimer levels (1536 ± 2347 vs 9652 ± 10,205 ng/mL, P < .01). Among the patients included on D0, only 32 had a DU on D5. Forty of them (55.55%) were not examined for the following reasons: 7 (9.7%) were previously diagnosed with venous thromboembolism on D0 and therefore were excluded on D5, 8 (11%) were transferred to the intensive care unit, 10 (14%) were discharged from the hospital, 5 (7%) died, and 10 (13.9%) were excluded because of technical issues. On D5, five (15.6%) patients had acute DVT in addition to those found on D0; three were distal and two proximal despite preventive anticoagulation with low-molecular-weight heparin. CONCLUSIONS: Hospitalized non-intensive care unit patients with COVID-19 pneumonia have a high frequency of venous thrombotic events justifying screening with DU.
