Erythrocyte concentrations of B1, B2, B6 but not plasma C and E are reliable indicators of nutrition status in the presence of systemic inflammation

Red cell concentrations of vitamins B1, B2 and B6 were not lower with an increasing systemic inflammatory response. In contrast, plasma concentrations of vitamin C and E were lower. Therefore, compared with plasma concentration, red cell concentrations of B1, B2 and B6 are likely to be more reliable measures of status in the presence of a systemic inflammatory response.
