Thiamine Deficiency as a Cause for Acute Circulatory Failure: An Overlooked Association in Western Countries.

A 42 year-old patient presented with circulatory failure and lactic acidosis. Clinical features, later coupled with biological tests, led to the diagnosis of wet beriberi syndrome and scurvy. Echocardiography showed a pattern of thiamine deficiency with high cardiac output and low vascular resistance. The patient's condition and biological parameters immediately improved after treatment injections of thiamine. Wet BeriBeri is often overlooked in western countries and is a diagnosis that must be considered based on history, and clinical and echocardiographical findings.
