==Overview==
[[Glucocorticoids]] are found to play an important role in the management of autoimmune pancreatitis via several ways such as efficacy in alleviating symptoms, decreasing the size of the [[pancreas]], reversing histopathologic features in patients with AIP,  and mprovement of lab findings. About 2/3rd of patients show good response to [[glucocorticoids]] with complete recovery, 25% may require a second course of [[glucocorticoids]], and a few patients with autoimmune pancreatitis may require continuous treatment. [[Immunomodulatory]] drugs such as [[azathioprine]] are usually used when, AIP patients have no response to [[steroid]] management, [[relapse]] occurs and patients cannot be weaned off [[steroids]].


==Medical Therapy==
==Medical Therapy==
*Pharmacologic medical therapy is recommended among patients with [disease subclass 1], [disease subclass 2], and [disease subclass 3].
*Pharmacologic medical therapies for [disease name] include (either) [therapy 1], [therapy 2], and/or [therapy 3].
*Empiric therapy for [disease name] depends on [disease factor 1] and [disease factor 2].
*Patients with [disease subclass 1] are treated with [therapy 1], whereas patients with [disease subclass 2] are treated with [therapy 2].

Overview

Glucocorticoids are found to play an important role in the management of autoimmune pancreatitis via several ways such as efficacy in alleviating symptoms, decreasing the size of the pancreas, reversing histopathologic features in patients with AIP, and mprovement of lab findings. About 2/3rd of patients show good response to glucocorticoids with complete recovery, 25% may require a second course of glucocorticoids, and a few patients with autoimmune pancreatitis may require continuous treatment. Immunomodulatory drugs such as azathioprine are usually used when, AIP patients have no response to steroid management, relapse occurs and patients cannot be weaned off steroids.

Medical Therapy

Role of 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:[5]
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.

Response to Glucocorticoids in patients with Biliary strictures:

Patients with biliary strictures have a variable response to glucocorticoids such as:[6][8][9][10][11]

Monitoring of clinical parameters in patients on glucocorticoid therapy:

Glucocorticoids are tapered depending upon following clinical parameters:[2][3][12][13]

  • 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.

Role of Immunomodulatory drugs:

Immunomodulatory drugs such as azathioprine are usually used when:

  • AIP patients have no response to steroid management.
  • AIP patients relapse, if steroids are discontinued.
  • AIP patients cannot be weaned off steroids.

The monoclonal antibody, Rituximab, is found to be effective in the management of AIP but further studies are required for the recommendation of routine use.[14][15][16]
