The current pandemic of COVID-19 caused thousands of deaths and healthcare professionals struggle to properly manage infected patients. This review summarizes information about SARS-CoV-2 receptor binding dynamics and intricacies, lung autopsy findings, immune response patterns, evidence-based explanations for the immune response, and COVID-19-associated hypercoagulability.

Celiac disease (CD) is a chronic intestinal immune-mediated disease occurring in genetically susceptible individuals who are exposed to gluten. Although it primarily affects the small intestine, CD has been associated with a wide spectrum of extraintestinal manifestations, including thromboembolism and cardiovascular events. ⋯ The pathogenetic mechanism of increasing hypercoagulability in CD is multifactorial and involves hyperhomocysteinemia due to malabsorption of vitamins B12, B6, and folic acid; endothelial dysfunction; acceleration of atherosclerosis; chronic inflammation; thrombocytosis; and thrombophilia. Therefore, in cases of thromboembolic complications and cardiovascular disease of obscure etiology, clinicians' awareness of possible celiac disease is warranted.

Coronavirus disease 2019 (COVID-19) and ischemic colitis: An under-recognized complication.
COVID-19 has spread worldwide, with more than 2.5 million cases and over 80,000 deaths reported by the end of April 2020. In addition to pulmonary symptoms, gastrointestinal symptoms have been increasingly recognized as part of the disease spectrum. ⋯ To our knowledge, there have not been any case reports of COVID-19 associated with ischemic colitis. Herein, we present the first case of a probable association of COVID-19 with ischemic colitis in a patient with a hypercoagulable state.

ReviewCOVID-19, thromboembolic risk, and Virchow's triad: Lesson from the past.
COronavirus Infectious Disease which started in 2019 (COVID-19) usually presents with the signs and symptoms of pneumonia. However, a growing number of recent reports highlight the fact that the infection may be by far more than only a respiratory disease. There is evidence of an increased thromboembolic risk in COVID-19 patients, with a variety of manifestations in terms of ischemic stroke, deep vein thrombosis, acute pulmonary embolism, acute myocardial infarction, systemic arterial embolism, and placental thrombosis. ⋯ Many of the drugs proposed and currently undergoing evaluation for the treatment of COVID-19 have one or more of the Virchow's triad elements as a target. The three factors outlined by Virchow are still able to explain the venous and arterial hypercoagulable state in the dramatic COVID-19 setting. Nowadays, we have decidedly more sophisticated diagnostic tools than Virchow had, but many of the challenges that we are facing are the same as Virchow faced in the 19th century.

Recent reports on outbreak of SARS-CoV-2 coronavirus (COVID-19) have shown its association with abnormal blood clots. The viral infection initiates inflammatory responses leading to endothelial damage and coagulation cascade dysfnction. Spread of COVID-19 has been associated with disseminated intravascular coagulation (DIC) and subsequent coagulopathy. Initially coagulopathy in COVID-19 patients result in significant elevation of D-dimer, fibrin/fibrinogen degradation products (FDP), and abnormalities in coagulatory parameters, which resulting in formation of thrombus and eventually death. ⋯ Findings of these research reports were summarized to recommend cautions for clinicians while treating COVID-19 patient. Screening of coagulatory parameters upon admission and during entire course of treatment is recommended, especially those who are at increased risk of thrombosis. Also, anticoagulant treatment can be used as thromboprophylaxis measure. Dose and duration of anticoagulation treatment requirement may vary and thus regular monitoring is needed.
