The Incidence of Acute Pancreatitis in the United States: Identification of Cases in an Electronic Healthcare Database With Supportive Laboratory Evidence

Association between glycemic status and the risk of acute pancreatitis: a nationwide population-based study

BACKGROUND

Although diabetes is reportedly associated with the occurrence of acute pancreatitis (AP), the risk of AP according to the duration and severity of diabetes is not yet clear. We aimed to investigate the risk of AP based on glycemic status and the presence of comorbidities using a nationwide population-based study.

METHODS

We enrolled 3,912,496 adults who underwent health examinations under the National Health Insurance Service in 2009. All participants were categorized by glycemic status as normoglycemic, impaired fasting glucose (IFG), or diabetes. Baseline characteristics and the presence of comorbidities at the time of health check-up were investigated, and the occurrence of AP was followed up until 31 December 2018. We estimated the adjusted hazard ratios (aHRs) for AP occurrence according to the glycemic status, duration of diabetes (new-onset, duration < 5 years, or ≥ 5 years), type and number of anti-diabetic medications, and presence of comorbidities.

RESULTS

During the observation period of 32,116,716.93 person-years, 8,933 cases of AP occurred. Compared with normoglycemia, the aHRs (95% confidence interval) were 1.153 (1.097-1.212) in IFG, 1.389 (1.260-1.531) in new-onset diabetes, 1.634 (1.496-1.785) in known diabetes < 5 years, and 1.656 (1.513-1.813) in patients with known diabetes aged ≥ 5 years. The presence of comorbidities associated with diabetes severity had a synergistic effect on the relationship between diabetes and AP occurrence.

CONCLUSION

As glycemic status worsens, the risk of AP increases, and there is a synergistic effect when comorbidities coexist. To reduce the risk of AP, active control of factors that can cause AP should be considered in patients with long-standing diabetes and comorbidities.

Fatal gastrointestinal bleeding associated with acute pancreatitis as a complication of Covid-19: a case report

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.
