Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) caused the ongoing pandemic of coronavirus disease 2019 (COVID-19), which presented as not only respiratory symptoms, but various digestive manifestations including pancreatic injury and acute pancreatitis (AP). The underlying mechanism is still unclear. Hypertriglyceridemia has become one of the leading causes of AP in recent years and hyperlipidemia is highly reported in COVID-19 cases. The current narrative review aimed to explore the associations between AP, COVID-19 and hyperlipidemia. Substantial cases of COVID-19 patients complicated with AP were reported, while the incidence of AP in the COVID-19 population was relatively low. Hyperlipidemia was common in COVID-19 patients with a pooled incidence of 32.98%. Hyperlipidemia could be a mediating factor in the pathogenesis of AP in COVID-19 patients. Further studies are warranted to clarify the relationship among AP, lipid metabolism disorders and COVID-19.

Coronavirus disease 2019 (COVID-19) presents mainly with mild symptoms and involvement of the respiratory system. Acute pancreatitis has also been reported during the course of COVID-19.

Our aim is to review and analyze all reported cases of COVID-19 associated acute pancreatitis, reporting the demographics, clinical characteristics, laboratory and imaging findings, comorbidities and outcomes.

We conducted a systematic search of Pubmed/MEDLINE, SciELO and Google Scholar to identify case reports and case series, reporting COVID-19 associated acute pancreatitis in adults.

There were no ethnicity, gender or language restrictions. The following terms were searched in combination:"COVID-19" OR "SARS-CoV-2" OR "Coronavirus 19" AND "Pancreatic Inflammation" OR "Pancreatitis" OR "Pancreatic Injury" OR "Pancreatic Disease" OR "Pancreatic Damage". Case reports and case series describing COVID-19 associated acute pancreatitis in adults were included. COVID-19 infection was established with testing of nasal and throat swabs using reverse transcription polymerase chain reaction. The diagnosis of acute pancreatitis was confirmed in accordance to the revised criteria of Atlanta classification of the Acute Pancreatitis Classification Working Group. Exclusion of other causes of acute pancreatitis was also required for the selection of the cases.

The following data were extracted from each report: the first author, year of publication, age of the patient, gender, gastrointestinal symptoms due to acute pancreatitis, respiratory-general symptoms, COVID-19 severity, underlying diseases, laboratory findings, imaging features and outcome.

Finally, we identified and analyzed 31 articles (30 case reports and 1 case series of 2 cases), which included 32 cases of COVID-19 induced acute pancreatitis.

COVID-19 associated acute pancreatitis affected mostly females. The median age of the patients was 53.5 years. Concerning laboratory findings, lipase and amylase were greater than three times the ULN while WBC counts and CRP were elevated in the most of the cases. The most frequent gastrointestinal, respiratory and general symptom was abdominal pain, dyspnea and fever, respectively. The most common imaging feature was acute interstitial edematous pancreatitis and the most frequent comorbidity was arterial hypertension while several patients had no medical history. The outcome was favorable despite the fact that most of the patients experienced severe and critical illness.

Our results are limited by the quality and extent of the data in the reports. More specifically, case series and case reports are unchecked, and while they can recommend hypotheses they are not able to confirm robust associations.

None.

The coronavirus disease 2019 (COVID-19) is known to cause gastrointestinal symptoms. Recent studies have revealed COVID-19-attributed acute pancreatitis (AP). However, clinical characteristics of COVID-19-attributed AP remain unclear. We performed a narrative review to elucidate relation between COVID-19 and AP using the PubMed database. Some basic and pathological reports revealed expression of angiotensin-converting enzyme 2 and transmembrane protease serine 2, key proteins that aid in the entry of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) into the pancreas. The experimental and pathological evaluation suggested that SARS-CoV-2 infects human endocrine and exocrine pancreas cells, and thus, SARS-CoV-2 may have a direct involvement in pancreatic disorders. Additionally, systemic inflammation, especially in children, may cause AP. Levels of immune mediators associated with AP, including interleukin (IL)-1β, IL-10, interferon-γ, monocyte chemotactic protein 1, and tumor necrosis factor-α are higher in the plasma of patients with COVID-19, that suggests an indirect involvement of the pancreas. In real-world settings, some clinical features of AP complicate COVID-19, such as a high complication rate of pancreatic necrosis, severe AP, and high mortality. However, clinical features of COVID-19-attributed AP remain uncertain due to insufficient research on etiologies of AP. Therefore, high-quality clinical studies and case reports that specify methods for differential diagnoses of other etiologies of AP are needed.

Clinical manifestations of Covid-19 vary widely among patients. Recent studies suggest that up to 15% of patients with severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) infections develop gastrointestinal symptoms. The location of virus-host cell receptors angiotensin-converting enzyme 2 and transmembrane serine protease 2 has an important role in the pathophysiology and presentation of disease. They are expressed in the respiratory tract, as well as other organs and tissues including exocrine and endocrine pancreatic cells. These cells are therefore a possible target for the virus, which could explain the relationship between SARS-CoV-2 infection and pancreatic injury. We report a disastrous collateral effect of the Covid-19 pandemic on a 33-year-old man with chronic renal insufficiency and asymptomatic SARS-CoV-2 infection, who developed acute pancreatitis. Inflammation progressed rapidly toward necrosis and the development of a peripancreatic pseudoaneurysm which subsequently ruptured, causing death.
