Autoimmune pancreatitis may be classified into two types; Type 1 AIP and Type 2 AIP or idiopathic duct-centric pancreatitis. Type 1 AIP meets the HISORt criteria, involves pancreas as one part of a systemic IgG4-positive disease. Type 2 consists of granulocytic lesions, does not involve IgG4-positive cells, has no systemic involvement, and is usually associated with inflammatory bowel disease. | Autoimmune pancreatitis may be classified into two types; Type 1 AIP and Type 2 AIP or idiopathic duct-centric pancreatitis.

Overview
Autoimmune pancreatitis may be classified into two types; Type 1 AIP and Type 2 AIP or idiopathic duct-centric pancreatitis. Type 1 AIP meets the HISORt criteria, involves pancreas as one part of a systemic IgG4-positive disease. Type 2 consists of granulocytic lesions, does not involve IgG4-positive cells, has no systemic involvement, and is usually associated with inflammatory bowel disease.
Classification
- Autoimmune pancreatitis can be
- Primary (when main pathology is in pancreas) or
- Secondary (when associated with other systemic autoimmune diseases such as IgG4-associated cholangitis, chronic sclerosing sialadenitis, tubulointerstitial nephritis, and ulcerative colitis)[1][2][3][4][5][6][7][8][9]
- Autoimmune pancreatitis may be classified into two types.
- Type 1 AIP
- Type 2 AIP or idiopathic duct-centric pancreatitis
Type 1 AIP:
- Type 1 AIP meets the HISORt criteria.[10][11]
- Type 1 AIP involves pancreas as one part of a systemic IgG4-positive disease.
- Type 1 AIP is more prevalent in males compared to females.
- Type 1 patients have high relapse rates when compared to type 2 patients.[12]
- Type 1 patients are usually older on presentation.
- Type 1 patients have higher prevalence of increased IgG4 levels.
- Type 1 patients have greater extrapancreatic organ involvement compared to Type 2 AIP patients.

Type 2 AIP or Idiopathic duct-centric pancreatitis:
- Type 2 consists of granulocytic lesions.
- Type 2 does not involve IgG4-positive cells.
- Type 2 has no systemic involvement.
- Type 2 has same predilection for both sexes.
- Type 2 AIP is usually associated with inflammatory bowel disease such as ulcerative colitis.
