Toxicology – Pancreatitis and Pancreatic Toxins
Overview
Pancreatitis is inflammation of the pancreas with multiple possible causes. While many cases are due to common conditions like gallstones and alcohol use, toxins, drugs, and metabolic abnormalities also play significant roles.
Common Causes
Gallstones
Gallstones are one of the leading causes of pancreatitis and, together with alcohol, account for the majority of cases.
Ethanol (Alcohol)
Alcohol is a major contributor to both acute and chronic pancreatitis due to its direct toxic effects on pancreatic cells.
Idiopathic
In some cases, no clear cause can be identified despite thorough evaluation.
Trauma
Blunt or penetrating injury to the abdomen can damage the pancreas and trigger inflammation.
Steroids and Hormones
Both corticosteroids and certain hormonal therapies have been associated with pancreatitis.
Infections
Viruses such as mumps, cytomegalovirus (CMV), and coxsackievirus can lead to pancreatic inflammation.
Malignancy
Pancreatic cancer may present with or contribute to pancreatitis and generally carries a poor prognosis.
Autoimmune Causes
Autoimmune pancreatitis is a form of chronic inflammation that often responds well to steroid therapy.
Scorpion Envenomation
Although uncommon, scorpion stings have been reported to trigger pancreatitis.
Metabolic Causes
Hypercalcemia
Elevated calcium levels, often due to hyperparathyroidism, can precipitate pancreatitis.
Hypertriglyceridemia
Very high triglyceride levels (typically >1,000 mg/dL) are a well-recognized cause.
Procedural Causes
Post-ERCP
Pancreatitis may occur after endoscopic retrograde cholangiopancreatography (ERCP), with a notable incidence in clinical practice.
Drug-Induced Pancreatitis
Common Drug Classes
Corticosteroids, antiretroviral (HIV) medications, chemotherapeutic agents, and thiazide diuretics are associated with pancreatic inflammation.
Specific Medications
Drugs known to cause pancreatitis include azathioprine, carbamazepine, cisplatin, didanosine, lamivudine, mercaptopurine, mesalamine, pentamidine, sulindac, tetracycline, valproic acid, and steroids.
