Acute recurrent pancreatitis: An autoimmune disease?

Table 4 A proposal of revised Korean diagnostic criteria for autoimmune pancreatitis

Criteria	Definition
CriterionI	Pancreatic imaging (essential):
	(1) CT: Diffuse enlargement (swelling) of pancreas and
	(2) ERCP: Diffuse or segmental irregular narrowing of main pancreatic duct
Criterion II	Laboratory findings:
	(1) elevated levels of IgG and/or IgG4 or
	(2) detected autoantibodies
Criterion III	Histopathologic findings
	Fibrosis and lymphoplasmocytic infiltration
Criterion IV	Association with other postulated autoimmune disease

Definite diagnosis: I + II + III + IV or I + II + III or I + II or I + III; Probable diagnosis: I + IV (Rediagnosed as “definite” if “response to steroids” is present); Possible diagnosis:I(Rediagnosed as “definite” if “response to steroids” is present).
