Shoshin Beriberi in a Child With Intestinal Failure: A Case Report

Hemodynamic collapse due to thiamine deficiency (Shoshin beriberi) may occur during acute illness in children with nutritional risk factors and should be considered in refractory hyperlactatemia. Timely treatment with parenteral thiamine can support dramatic hemodynamic recovery. Treatment of suspected thiamine deficiency should not be delayed for laboratory confirmation as current thiamine reference ranges correlate poorly with clinical severity, and functional testing may not be readily available.
