Acute pancreatitis as a complication of Covid-19 is infrequent.1 Despite reports of elevated amylase/lipase and/or acute pancreatitis in some patients with Covid-19,2 the exact role that SARS-CoV-2 plays in causing acute pancreatitis is unclear at this time.
A retrospective study of over 11,000 hospitalized patients with Covid-19 in the U.S. found a point prevalence of acute pancreatitis of only 0.27%,3 while another retrospective study of Covid-19 patients seen in Spanish emergency rooms reported acute pancreatitis in only 0.07% of cases.4 Of interest, in the latter study, Covid-19 was associated with lower frequency of acute pancreatitis. Further adding to the controversy on the causative role of Covid-19 is lack of an observed increase in the incidence of acute pancreatitis during Covid-19 pandemic. 1
An earlier study from China reported mild elevation (<3x upper limits of normal) of amylase and/or lipase in 17% of patients with Covid-19 pneumonia, none of whom had abdominal pain. 5
The temporal relationship between Covid-19 and acute pancreatitis has varied from abdominal symptoms at the onset of Covid-19 symptoms to days after diagnosis of Covid-19? 1
Despite these disparate findings, Covid-19 related acute pancreatitis or pancreatic injury is plausible. Pancreatic ductal, acinar and islet cells express ACE2, an important receptor for SARS-CoV-2.1 Infection in the GI tract (virus can easily be found in the stool) may potentially spread from the duodenal epithelium to the pancreatic duct and the pancreatic parenchyma itself. Immune-mediated inflammatory response or endotheliitis caused by SARS-CoV-2 may also potentially explain reports of pancreatic injury in Covid-19. 1,2
Bonus Pearl: Did you know that SARS-CoV-2 has been found in pancreatic tissue of some patients who succumbed to Covid-19 and has been shown to infect human pancreatic beta cells in-vitro.6 Perhaps we should be on the lookout for diabetes as a consequence of Covid-19 as well!
