Azathioprine (AZA) can cause acute pancreatitis (AIP) in autoimmune hepatitis (AIH) patients. Early recognition and switching to mycophenolate mofetil (MMF) ensures recovery and continued immunosuppression.
Area of Science:
- Gastroenterology
- Hepatology
- Clinical Pharmacology
Background:
- Autoimmune hepatitis (AIH) requires long-term immunosuppression.
- Azathioprine (AZA) is a common immunosuppressant, but carries risks.
- Drug-induced pancreatitis is a potential adverse effect of AZA therapy.
Purpose of the Study:
- To report a case of acute pancreatitis induced by azathioprine (AZA) in a patient with autoimmune hepatitis (AIH).
- To emphasize the importance of recognizing azathioprine-induced pancreatitis (AIP) early.
- To highlight mycophenolate mofetil (MMF) as an alternative immunosuppressant.
Main Methods:
- Case report of a 67-year-old woman with biopsy-proven AIH.
- Clinical presentation, laboratory findings, and imaging studies were analyzed.
- Medication history, specifically AZA initiation, was reviewed.
- Exclusion of common pancreatitis etiologies.
Main Results:
- The patient developed acute pancreatitis within weeks of starting AZA and budesonide.
- Common causes of pancreatitis were excluded.
- Discontinuation of AZA led to complete clinical recovery.
- Transition to MMF for immunosuppression was successful.
Conclusions:
- Azathioprine-induced pancreatitis (AIP) is a critical diagnosis to consider in AIH patients starting AZA.
- Prompt recognition and drug withdrawal are key to patient recovery.
- Mycophenolate mofetil (MMF) is a safe and effective alternative for immunosuppression in patients intolerant to AZA.

Acute Pancreatitis I: Introduction
Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
Chronic Pancreatitis I: Introduction
Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
