Abstract:
Severe acute respiratory syndrome–coronavirus-2 (SARS-CoV-2) enters cells using the angiotensin converting enzyme 2 (ACE2), which are expressed by the respiratory tract endothelium, epithelial cells of the stomach, duodenum, ileum, rectum, cholangiocytes, and hepatocytes. Pathological examinations of these organs are not feasible method of diagnosis but can explain pathological changes, pathogenesis of the disease, and the cause of death in COVID-19 cases. In this review, we performed a literature search for COVID-19-related pathological changes seen during post-mortem examinations in different organs of the body including the lungs, gastrointestinal tract, liver, kidney, skin, heart and blood. Our findings showed that SARS-CoV-2 has damaging effects on many organs, probably due to the host immune responses to the presence of the virus. It is recommended that both antiviral and immunomodulatory agents should be considered in the management of COVID-19 patients for better prognosis, and clinical outcome.
