Severe metabolic acidosis and heart failure due to thiamine deficiency.
We report the case of a male patient with severe metabolic acidosis and heart failure caused by thiamine deficiency. He was admitted in August 1998 to the Tokai University Oiso Hospital because of severe dyspnea. The patient was diagnosed with heart failure and metabolic acidosis of unknown causes based on arterial blood gas analysis, chest x ray, and ultrasonic echocardiographic examinations. Our previous experience in treating a patient with thiamine deficiency caused by total parenteral nutrition without thiamine supplementation suggested that this patient was deficient in thiamine. The serum thiamine level was low and the lactate level was high. After intravenous administration of thiamine, the acidosis and heart failure disappeared. Dietary analysis showed that thiamine intake was low (0.32 mg/1000 kcal/d). Thiamine deficiency should be included in the differential diagnosis when encountering cases of heart failure with severe metabolic acidosis, even in developed countries.
