![]() In discussion, the authors of this report describe an animal study that demonstrated the hypoglycemic effect of MDMA. The cause of severe hypoglycemia in this case was eventually attributed to MDMA (ecstasy) intoxication. The patient had a history of suicidal ideation and the possibility that she had self-administered exogenous insulin was considered.īlood testing revealed raised insulin and C-peptide levels, results that are consistent with excessive production of endogenous insulin rather than administration of exogenous insulin. ![]() Without evidence of any pathology to explain the protracted severe hypoglycemia, it became clear that ingested drugs were the cause. The patient required glucose infusion for a further 30 hours before eventual stabilization of blood glucose concentration.ĭuring this time she was successfully extubated. ![]() Salicylate, paracetamol (acetaminophen) and alcohol were not present in the patient’s blood and other blood-chemistry testing revealed no abnormality, save reduced potassium (2.9 mmol/L (53 mg/dL)).ĭespite the continuing infusion of 10 % dextrose, blood glucose fell once again to 1.5 mmol/L (27 mg/dL) so the infusion was switched to 20 % dextrose delivered at the higher rate of 200 mL/hr, with a schedule of blood glucose testing every 30 minutes. Laboratory testing of urine revealed presence of tetrahydrocannabinol (cannabis), amphetamines and MDMA (ecstasy). Vital signs were within normal limits, physical examination was unremarkable except that she had pinpoint pupils. ![]() On arrival in ICU the patient was stable, sedated and still intubated. A third dose of glucose was administered IV (100 mL of 50 % dextrose) and additionally an infusion drip of normal saline with 10 % dextrose delivered at a rate of 100 mL/hr was started. But just prior to transfer to ICU blood glucose was checked and once again found to be very low (2.0 mmol/L (36 mg/dL)). Within 30 minutes of this treatment her blood glucose had risen to 5.6 mmol/L (101 mg/dL). On arrival at the emergency department of this second hospital the patient’s blood glucose was just 2.6 mmol/L (47 mg/dL) and a second larger dose of glucose was administered IV (100 mL of 50 % dextrose). The patient was then transferred to a tertiary care hospital for intensive care management. Initial blood testing revealed her blood glucose was just 1.1 mmol/L (20 mg/dL).Ī 50 mL bolus of 50 % dextrose was administered intravenously and her glucose soon increased to 3.4 mmol/L (61 mg/dL). She was intubated to allow mechanical ventilation. Other less common causes occurring in the non-diabetic population include severe liver disease, Addison’s disease, insulinoma (insulin-secreting tumor), alcohol, and rarely, a range of drugs not used in the treatment of diabetes.Ī recently published case history of severe protracted hypoglycemia concerns a 29-year-old woman with a history of depression and drug abuse who was brought to her local hospital after being found collapsed on the floor and only minimally responsive. The most common cause of hypoglycemia is diabetes-treatment drugs (exogenous insulin and other blood glucose-lowering agents) so that the vast majority of patients presenting with hypoglycemia have a history of diabetes. Severe hypoglycemia (blood glucose <2.0 mmol/L (36 mg/dL)) can cause convulsions, reduced consciousness, coma and ultimately death if glucose (dextrose) is not administered. These symptoms include: sweating, feeling of hunger, palpitations, anxiety, confusion and headache. Hypoglycemia (reduced blood glucose concentration) is often defined as blood glucose <2.2 mmol/L (<40 mg/dL) although symptoms may occur at higher concentration (up to 3.0 mmol/L (54 mg/dL)). Insulin secretion causes decrease in blood glucose concentration and glucagon secretion causes increase in blood glucose concentration. Blood glucose concentration is normally maintained within the approximate range of 3.5-8.5 mmol/L (63-153 mg/dL) largely by the synergistic opposing action of two pancreatic hormones: insulin and glucagon.
