Causes and Management of Acute Pancreatitis

Etiology and Ranking

• Hypertriglyceridemia is the third most common cause of acute pancreatitis, accounting for 4-10% of cases 1
• The American College of Gastroenterology and other guidelines suggest that gallstones are the leading cause, responsible for 45-60% of cases, followed by alcohol, which accounts for 20-25% of cases overall 2

Clinical Significance and Management

• Hypertriglyceridemia-associated acute pancreatitis carries a worse prognosis than other etiological factors 1
• Initial management includes nil by mouth for 24-48 hours, aggressive fluid resuscitation, and analgesia, with etiology-specific interventions such as in-hospital pharmacological treatment with insulin and/or heparin, and plasmapheresis for severe cases 1

Prevention of Recurrence

• Long-term management to prevent recurrent episodes includes a low-fat diet, weight loss encouragement, treatment with a fibrate as first-line therapy, and addition of a statin if concurrent hypercholesterolemia is present 1
• Tight regulation of triglyceride levels after the initial presentation significantly reduces recurrence risk 1

Drug-Induced Pancreatitis

• Azathioprine and 6-mercaptopurine can cause pancreatitis in approximately 4% of treated IBD patients, typically within the first 3-4 weeks of treatment, according to the European Crohn’s and Colitis Organisation 3
• Mesalazine (5-ASA compounds) also carries a risk of pancreatitis, though it is much lower than thiopurines 3
