COVID-19 and venous thromboembolism: part of a multisystem disease.

We read with great interest recent scientific letters addressing abdominal aspects of COVID-19. Like Martin-Falquina IC et al. regarding the thrombotic nature of acute pancreatitis (AP) in a patient with COVID-19, our patient with AP was previously anticoagulated. The association in the medical literature between viral infections (such as those caused by the human immunodeficiency viruses, hepatitis C and influenza) and venous thromboembolism (VTE) has again become evidence in the scientific community whether in 2017 in the epidemic of Chicungunya and Zika or more recently in the current COVID-19 pandemic.
