The gastrointestinal system may be affected by COVID-19 infection with an incidence variable from 3% up to 79%. Several works show that the pancreas, both in its exocrine and endocrine function, can be affected by this viral infection, although this organ has been poorly analyzed in this current epidemic context. This mini-review aims to provide a summary of available studies on exocrine pancreas involvement during COVID-19 infection. A search through MEDLINE/PubMed was conducted on the topic in hand. With regard to exocrine function, some studies highlight the presence of an associated hyperenzymemia (hyperamylasemia, hyperlipasemia), while others describe isolated and rare cases of acute pancreatitis. More attention should be paid to pancreatic impairment in subjects with COVID-19, as this may prove to be one of the elements aggravating its clinical course. Indeed, acute pancreatitis, especially when presenting in severe forms with hyperstimulation of the pro-inflammatory response, may represent a crucial factor in the progression of COVID-19, entailing both an increase in hospitalization days and in mortality rate.
