Hyperinsulinemic hypoglycemia in adults - 12/10/17
Résumé |
The diagnosis of a hypoglycemic disorder requires a high level of suspicion, careful assessment of the patient for the presence of mediating drugs or a predisposing illness, and, where indicated, methodical evaluation on the basis of well-defined diagnostic criteria.
The diagnostic burden is heaviest for healthy-appearing persons with episodes of confirmed neuroglycopenia. Our criteria for insulin mediation of hypoglycemia are: plasma insulin ≥18 pmol (ICMA immunochemiluminometric assay.), C-peptide ≥200pmol/L (ICMA), proinsulin ≥5pmol/L (ICMA), ≥OH butyrate, ≤2.7mmol/L and generous (1.4mmol/L) response of plasma glucose to IV glucagon administered when the patient is hypoglycemic. Sulfonylureas, meglitinides and insulin antibodies should be sought in the plasma of any hypoglycemic patient.
