A 64-year-old male patient with diabetic nephropathy had been treated with maintenance hemodialysis therapy for 4 years, and had developed disturbed consciousness. The disturbance was firstly noticed by a primary care doctor who recognized slow responses in conversation. Prior to developing this symptom, the patient had noticed a loss of appetite for about 2 weeks. During a period of observation at an outpatient clinic, the symptoms became worse. He was admitted to a primary care hospital for 10 days, but his consciousness level deteriorated and he became unconscious (JCS 200). About 1 month after the onset of symptoms, the patient was transferred to our hospital. A brain computed tomography (CT) scan and magnetic resonance imaging (MRI) showed typical abnormal lesions in the aquaduct of the midbrain and thalamus, and a diagnosis of Wernicke's encephalopathy was made. In addition, the patient's serum thiamine level was extremely low (7 ng/ml). He received immediate treatment with intravenous thiamine administration (150 mg/day), and this significantly improved his symptoms (JCS 2). Dialysis patients may develop water-soluble vitamin deficiency as a result of the combination of reduced oral intake and increased loss of vitamins into the dialysate. Wernicke's encephalopathy should be considered as one of many causes of disturbed consciousness in hemodialysis patients. A rapid diagnosis and adequate treatment are essential in order to minimize long-term neurological sequelae.

PMID:Severe thiamine deficiency resulted in Wernicke's encephalopathy in a chronic dialysis patient. 1718 35

A 75-year-old man with diabetic nephropathy treated with hemodialysis visited to a medical office because of slight fever, and received intravenous glucose infusion without any vitamins. Thereafter, he noticed gait disturbance and began to tell inconsistent stories. He was admitted to our hospital due to aggravation of these symptoms. On admission, he was disoriented and not able to sit by himself because of severe truncal ataxia without weakness. He had also gaze direction nystagmus. Based on clinical features, we considered him as having Wernicke's encephalopathy (WE) and treated him with 100 mg thiamine per day. The thiamine supply diminished these symptoms soon. Plasma thiamine level prior to the administration was 7 ng/ml, which confirmed the diagnosis. MRI did not disclose any abnormalities frequently seen in WE. WE is a life-threatening disease, and 'early detection, early cure' is important for recovering without sequelae. The thiamine deficiency is often seen in dialysis patients because of dietary restrictions as well as its loss during dialysis. This case gives us the caution; when hemodialysis patients present acute/subacute gait disturbance and/ or abnormal mental state, we should consider WE. Furthermore, high-risk patients, such as elderly patients under hemodialysis may need some supplement including thiamine even at preclinical stage.
