Risk Factors for the Development of Diabetes Mellitus After Distal Pancreatectomy

The criteria for the diagnosis of diabetes developed by American Diabetes Association (1) FPG (fasting plasma glucose) ≥ 126 mg/dL (7.0 mmol/L). Fasting is defined as no caloric intake for at least 8 h.* OR (2) 2-h PG (plasma glucose) ≥ 200 mg/dL (11.1mmol/L) during an OGTT (oral glucose tolerance test). The test should be performed as described by the WHO, using a glucose load containing the equivalent of 75 g anhydrous glucose dissolved in water.* OR (3) A1C ≥ 6.5% (48 mmol/mol). The test should be performed in a laboratory using a method that is NGSP certified and standardized to the DCCT assay.* (lower-upper limit: 4.5%-6.3% in PUMCH) OR (4) In a patient with classic symptoms of hyperglycemia or hyperglycemic crisis, a random plasma glucose ≥ 200 mg/dL (11.1 mmol/L).

*In the absence of unequivocal hyperglycemia, results should be confirmed by repeat testing.

The categories of prediabetes (increased risk for diabetes)

(1) Impaired fasting glucose (IFG): FPG 100 mg/dL (5.6 mmol/L) to 125 mg/dL (6.9 mmol/L). (3.6 - 6.1 mmol/L in PUMCH) OR (2) Impaired glucose tolerance (IGT): 2-h PG in the 75-g OGTT 140 mg/dL (7.8 mmol/L) to 199 mg/dL (11.0 mmol/L). The test should be performed as described by the WHO, using a glucose load containing the equivalent of 75 g anhydrous glucose dissolved in water.

OR (3) A1C 5.7-6.4% (39-46 mmol/mol)
