Background: Beriberi is endemic in South-east Asia. Diagnosis is based on clinical findings, but correlation of clinical features with blood thiamine concentrations is uncertain. Objectives: To investigate in tachypnoeic Cambodian infants the correlation between whole blood thiamine diphosphate (TDP) concentrations, clinical findings and blood TDP levels after therapy. Methods: Infants hospitalised with tachypnoea were enrolled from October 2011 to January 2012. Initial clinical features, diagnostic test results and final diagnoses were recorded. Blood for TDP determination was collected prior to treatment and at discharge. Matched infants from the general outpatient clinic with minor complaints were enrolled as controls. Thiamine was administered at the discretion of the treating paediatrician. Results: Of the 47 tachypnoeic and 47 control infants, median initial blood TDP concentrations were 83 and 93 nmol/L, respectively (P = 0·69), and were below the estimated limit of normal (
