The riboflavin status of multiple-trauma accident patients receiving nutritional support was evaluated. Riboflavin excretion, erythrocyte glutathione reductase (EGR-AC), erythrocyte riboflavin (ERC-B2), nitrogen balance and riboflavin, and N and energy intake were assessed periodically. Mean intakes of N, energy and riboflavin were less than recommended. All patients but 1 were in negative N balance; however, patients retained riboflavin except when N and energy intakes were very low. EGR-AC values were within normal range and did not reflect changes in riboflavin retention. ERC-B2 values were also within normal range but decreased over time in patients with the largest riboflavin excretion and most negative N balance. ERC-B2 in combination with riboflavin intake and excretion data may offer a suitable method for assessing riboflavin status in multiple-trauma patients.
