Beri-Beri and Wernicke Encephalopathy in a Thirty-Year-Old Male

A 30-year-old Turkish male was found lethargic and surrounded by vomit. At the hospital, severe hypernatremic dehydration and acute kidney failure were evident. His conscious level improved with fluid resuscitation. A differential diagnosis of altered mental status was considered. A complete clinical triad of Wernicke encephalopathy (WE), supported by MRI findings, was compatible with thiamine deficiency. Previous bariatric surgery was later confirmed. Despite no clinical signs of heart failure, a high level of NT-proBNP (N-terminal prohormone brain natriuretic peptide) and a dilated, hypokinetic myocardiopathy detected on the echocardiogram led us to assume beri-beri heart disease. High-dose intravenous thiamine, ACE (angiotensin conversing enzyme) inhibitors, beta-blockers, and physical therapy were initiated with remarkable improvement in his clinical condition.
