Abstract
Despite the emerging data about the thrombophilic effect of the novel coronavirus [1] , the relation between coagulation disorders and the COVID-19 pandemic is still not well understood. Various studies pointed to the significant role of the COVID-19 induced cytokine storm in development of the hypercoagulable state which leads to serious thromboembolic complications [2,3] . Some studies report the development of severe immune thrombocytopenia induced by the novel coronavirus [4] . Other studies found a correlation between COVID-19 disease and the development of disseminated intravascular coagulation (DIC) [5]. Patients with severe COVID-19 disease have an increased risk for development of gastrointestinal bleeding (GI) which may be related to stress [6] , critical illness or mechanical ventilation [7] . Further studies showed the ability of the novel coronavirus to infect the epithelial cells of the GI tract [8] . Moreover, some data pointed to the ability of the virus even to infect the endothelium of blood vessels [9]. The relation between the COVID-19 pandemic and GI bleeding deserves more studies [10]. We present a case of GI bleeding in a patient with severe COVID-19 disease. We assume that COVID-19 disease can be a predominant factor for the development of DIC and GI bleeding.
