Lupus anticoagulant single positivity at acute phase is not associated with venous thromboembolism or in-hospital mortality in COVID-19

Antiphospholipid antibodies (APA) clinical relevance in COVID-19 is controversial. We aimed to investigate the prevalence and prognostic value of conventional and non-conventional APA in COVID-19 patients. This study was a multi-centric, prospective observational French cohort of patients hospitaliz...

description Antiphospholipid antibodies (APA) clinical relevance in COVID-19 is controversial. We aimed to investigate the prevalence and prognostic value of conventional and non-conventional APA in COVID-19 patients. This study was a multi-centric, prospective observational French cohort of patients hospitalized for COVID-19 suspicion. 249 patients were hospitalized for suspected COVID-19, including 154 with confirmed COVID-19 and 95 not confirmed. We found a significant increase in lupus anticoagulant (LA) positivity among COVID-19 positive patients (60.9% versus 23.7% in non-COVID19 patients, p

COVID-19 patients with LA positivity had higher levels of fibrinogen (6.0 IQR 5.0-7.0 versus 5.3 g/L IQR 4.3-6.4, p=0.028) and C-reactive protein (CRP, 115.5 IQR 66.0-204.8 versus 91.8 mg/L IQR 27.0-155.1, p=0.019). Univariate analysis did not show any association between LA positivity and higher risk of venous thromboembolism (VTE, OR 1.02, 95% CI 0.44-2.43, p=0.95) or in-hospital mortality (OR 1.80, 95% CI 0.70-5.05, p=0.24). Unadjusted and adjusted (to CRP, age and sex) Kaplan-Meier survival curves according to LA positivity confirmed the absence of association with VTE or in-hospital mortality (unadjusted: p=0.64 and p=0.26, respectively; adjusted: hazard ratio = 1.13 95% CI 0.48-2.60 and 1.80 95% CI 0.67-5.01).
