P-26 Recurrent diabetic ketoacidosis-like symptoms and factitious hyperglycemia as a Munchausen syndrome in diabetes mellitus type 1: A case report

Abstract

Abstract Introduction Factitious disorder (FD) is diagnosed by pretending to be sick with no abnormal examination or paraclinical study in the presence of psychiatric symptoms which also is named Munchausen's syndrome. The prevalence of the disease among hospitalized patients is approximately 9%. Clinical Case A 17-year-old girl with type 1 diabetes mellitus was referred to endocrinology clinic with uncontrolled diabetes, dizziness, abdominal pain, nausea and vomiting. She was treated with multiple daily insulin during 4 years but in last 8 months her self-monitoring of blood glucose ranges was out of control and have BG (blood glucose) different ranges of 40-560mg/dl. She was admitted to control her brittle diabetes with insulin infusion but even with high dose insulin infusion up to 20 IU/hr mostly her BS were above 400mg/dl. The notable point was that BG level was measured by laboratory was lower than glucometer. She also complained of severe abdominal pain and nausea during admission that mimics diabetic ketoacidosis in the presence of hyperglycemia despite the lack of ketonuria and metabolic acidosis. She admitted to hospital several times over the last year to control high level of BG. In psychiatric examination, she has good cooperation in response to questions. Mental Status Examination was not normal. Her mood was depressive and behavior was aggressive. Mild depressive symptoms and borderline features were seen in her Rorschach test. Finally because of high suspicion to associated psychiatric problems, to find the cause of high BG despite high insulin dose prescription, patient behaviors were monitored insensible. We found that she impregnated her finger to the date palm a few minutes before blood glucose check with glucometer devices at times when she is alone in the room. The patient had different deceptive behaviors depending on the method of treatment. But the answer to the question of why the patient was not suffering from hypoglycemia despite high doses of insulin injection is, when insulin infusion by pump was started to control high BG, intravenous cannula secretly separated from insulin infusion set and insulin thrown away. Also she secretly eats fruit juice and jam to prevent hypoglycemic attack for high-dose insulin injection. She took the water into the insulin pen instead of insulin and injected so that the nurses did not notice. Frauds were changed by switching the treatment methods. HbA1c was requested last week of hospitalization which shows 8%. Although all BGwas above 300 mg/dl during this prolonged hospitalization, it did not match with chronic hyperglycemia. Conclusion The main purpose of this article was in relation to a diabetic patient with brittle diabetes, difficulty in control BG level, discrepancies between patient symptoms and sings, factitious disorder or Munchausen syndrome should always be in our mind.
