Importance of Insulin Immunoassays in the Diagnosis of Factitious Hypoglycemia
نویسندگان
چکیده
We report two cases emphasizing the importance of insulin assays for evaluation of hypoglycemia in diabetic patients. Case 1 was a 96/12-year-old female patient with type 1 diabetes mellitus and case 2 was a 1010/12-year-old male patient with DIDMOAD. Both patients were on a basal-bolus insulin regimen. Both were admitted because of persistent hypoglycemia. Analyses of serum samples obtained at the time of hypoglycemia initially showed low insulin and C-peptide levels. Recurrent episodes of unexplained hypoglycemia necessitated measurement of insulin levels by using different insulin assays, which revealed hyperinsulinemic hypoglycemia with low C-peptide levels, findings which confirmed a diagnosis of factitious hypoglycemia. Surreptitious administration of insulin should not be excluded in diabetic patients with hypoglycemia without taking into account the rate of cross-reactivity of insulin analogues with the insulin assay used.

Recognizing factitious hypoglycemia in the family practice setting.
BACKGROUND Factitious hypoglycemia is a deliberate attempt to induce a low serum glucose level using either insulin or oral hypoglycemic agents. Sulfonylurea-induced hypoglycemia is more common than incidents of insulin abuse, and hypoglycemia caused by these oral agents is biochemically indistinguishable from insulinoma. METHODS We describe a case of factitious hypoglycemia resulting from in...
متن کاملFactitious hyperinsulinism leading to pancreatectomy: severe forms of Munchausen syndrome by proxy.
Clinical history and inappropriate insulin secretion during hypoglycemic episodes permit the diagnosis of hyperinsulinism. We report 2 cases of factitious hyperinsulinism leading to partial pancreatectomy. Case 1 was an 8-year-old girl who presented with severe hypoglycemia and elevated insulin and C-peptide levels. Catheterization of pancreatic veins was performed to localize the excess insuli...
متن کاملA Comparative Study of Blood Glucose Measurements Using Glucometer Readings and the Standard Method in the Diagnosis of Neonatal Hypoglycemia
Background: Hypoglycemia is one of the most common neonatal disorders, associated with severe complications. There has been a great deal of controversy regarding the definition and screening of hypoglycemia. Therefore, in this study, we aimed to determine a cut-off value for blood glucose level in glucometer readings. Methods: This cross-sectional study was conducted on 238 newborns at risk of ...
متن کاملInsulinoma Diagnosed with Endoscopic Ultrasound – Two Cases
We present two cases of insulinoma diagnosed by endoscopic ultrasound (EUS) after initial imaging was unrevealing. Both patients presented with refractory hypoglycemia and were found to have high c-peptide and insulin levels suspicious for insulinoma with evaluation for factitious causes (sulfonylurea, and meglitinides screening) being ruled out. However, imaging with computed tomography (CT) o...
