Overview
Medical Therapy
Glucocorticoids:
- Preferred regimen : Prednisone is usually administered at an initial dose of 40 mg/d for 4 weeks followed by a taper of the daily dosage by 5 mg/wk depending upon the clinical parameters.
- Glucocorticoids are found to play an important role in the management of autoimmune pancreatitis via several ways such as:[1][2][3][4]
- Efficacy in alleviating symptoms
- Decreasing the size of the pancreas
- Reversing histopathologic features in patients with AIP
- Improvement of lab findings such as
- Resolution of hypergammaglobulinemia[5]
- Autoantibodies become undetectable
Response to Glucocorticoids:
- About 2/3rd of patients show good response to glucocorticoids with complete recovery.[6][7][8]
- Approximately 25% may require a second course of glucocorticoids.
- A few patients with autoimmune pancreatitis may require continuous treatment .
Monitoring of clinical parameters in patients on glucocorticoid therapy:
- Glucocorticoids are tapered depending upon following clinical parameters:
- Relief of symptoms
- Serial changes in abdominal imaging of the pancreas and bile ducts
- Decreased serum γ-globulin and IgG4 levels
- Improvements in liver function tests
