Thiamine deficiency is mainly encountered in alcoholics or food faddists, b
ut it may complicate chronic dialysis because of low intake and accelerated

at thiamine deficiency, with a consequent dysfunction of the basal ganglia,
may induce chorea in HD patients. (C) 2001 by the National Kidney Foundati
