Management Strategies for Posttransplant Diabetes Mellitus after Heart Transplantation: A Review
Box 1
WHO and ADA criteria for the diagnosis of diabetes mellitus, impaired fasting glucose (IFG), and impaired glucose tolerance (IGT) [
16,
17].
The following criteria have been recommended for the diagnosis of diabetes when screening patients for diabetes mellitus after transplant | Symptoms of diabetes plus random plasma glucose concentrations ≥ 200 mg/dl (11.1 mmol/l). Random is defined as any time of day | without regard to time since last meal. The classic symptoms of diabetes include polyuria, polydipsia and unexplained weight loss. | OR | FPG ≥ 126 mg/dl (7.0 mmol/l). Fasting is defined as no caloric intake for at least 8 hours. | OR | 2-hour PG ≥ 200 mg/dl (11.1 mmol/l) during an oral glucose tolerance test. The test should be performed as described by WHO, | using a glucose load containing the equivalent of 75 g anhydrous glucose, dissolved in water. | A confirmatory laboratory test based on measurements of plasma glucose should be performed on another day in the absence of | unequivocal hyperglycemia accompanied by acute metabolic decompensation. | Criteria for IFG or IGT | IFG | FPG ≥ 110 mg/dl (6.1 mmol/l) and <126 mg/dl (7.0 mmol/l). | IGT | 2-hour PG ≥ 140 mg/dl (7.8 mmol/l) and <200 mg/dl (11.1). | It is important to identify which test is used since the 2-hour OGTT cut-off will identify more people with IGT than those identified | with IFG from the FPG test. | FPG, fasting plasma glucose; IFG, impaired fasting glucose; IGT, impaired glucose tolerance; OGTT, oral glucose tolerance test; PG, | plasma glucose. |
