Abstract
BACKGROUND: Severe hypoglycemia leading to permanent brain damage is rare in non-diabetic population. We present one such case where chronic alcoholism combined with prolonged fasting lead to such a state and patient ended in a persistent vegetative state. CASE REPORT: A 50 year old Asian woman with past history of chronic alcoholism and hepatitis C was found unresponsive in her house after drinking alcohol consecutively for 2 days. Finger-stick glucose done by paramedics was <20 mg/dl. She was given 50 ml of 50% dextrose without any neurological response. On arrival in the emergency department patient was found to be comatose with only withdrawal response to deep painful stimuli and a negative babinski's sign. Computed tomogram of the head revealed mild cerebral atrophy. After an extensive work up a diagnosis of alcoholic ketoacidosis with hypoglycemia related encephalopathy was made. CONCLUSIONS: Alcohol induced ketoacidosis is usually associated with normal blood glucose. The probable etiology of low blood sugar in our patient was alcohol-induced inhibition of gluconeogenesis along with starvation. The prolonged hypoglycemia caused cortical damage simulating ischemic brain damage. Ten months in to follow-up patient is still in persistent vegetative state with no noticeable neurological recovery.
