Acute Pancreatitis in a Patient With COVID-19 After the Resolution of Respiratory Symptoms.

J Investig Med High Impact Case Rep 2021 Jan-Dec;9:23247096211024773

Northwestern Medicine McHenry Hospital, McHenry, IL, USA.

The gastrointestinal (GI) involvement, including acute pancreatitis (AP) from the novel coronavirus disease-2019 (COVID-19), is increasingly being reported. Recent evidence suggests that the pathogenesis of COVID-19 is mediated by the angiotensin-converting enzyme 2 (ACE-2) receptors and transmembrane protease serine 2 (TMPRSS2) for "priming," which is highly expressed in the pancreas. To our knowledge, there is no other reported case of AP associated with COVID-19 after the respiratory symptoms are resolved. Read More
