The association between plasma ferritin concentration and vitamin A and E status was studied in 17 children aged 15-72 months with severe oedematous malnutrition. The controls were 10 children of similar age who were apparently well and with no obvious signs of clinical malnutrition. Plasma ferritin concentration in the patients was significantly higher than that in the control children. Conversely, the plasma concentrations of beta-carotene, alpha-tocopherol and retinol in patients were significantly lower than those in plasma of control children. The median (interquartile range) plasma alpha-tocopherol concentration of patients, 6.03 (5.29-9.50) mumol/l, is below the threshold of vitamin E deficiency (11.6 mumol/l). Fifteen of 17 (88%) malnourished patients were found to have plasma tocopherol concentrations below the normal threshold. However, all the patients had a tocopherol: cholesterol ratio greater than 2.22, indicating adequate vitamin E status for the level of cholesterol present in plasma. Twelve of 17 patients (70.5%) had plasma retinol concentration less than 0.70 mumol/l, indicative of marginal vitamin A status, while 3 patients had plasma retinol concentrations less than 0.35 mumol/l, indicating vitamin A deficiency. The median (interquartile range) plasma retinol concentration of patients, 0.51 (0.41-0.93) mumol/l, is significantly less than that of control children, 0.96 (0.74-1.09) mumol/l; p less than 0.01 Mann Whitney U test. Furthermore, anaemia (Hb less than 110 g/l) was widespread in the patients. The results also indicate no significant correlation between elevated ferritin concentration and the concentrations of beta-carotene, retinol and alpha-tocopherol in the patients' plasma.(ABSTRACT TRUNCATED AT 250 WORDS)
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
