    Abstract:
    In 68 Sudanese children with severe protein-energy malnutrition, age 1-4 years, the selenium status was investigated and the results were compared with those of healthy Sudanese and German children. The median selenium content in plasma of healthy Sudanese children (x = 59 micrograms/L) and with those of marasmus (x = 57 micrograms/L) were found to be in the same range. It was lower than in healthy German children (x = 82 micrograms/L). Patients with marasmic kwashiorkor exhibited still lower values (x = 42 micrograms/L. Within each group of malnourished children (marasmus, marasmic kwashiorkor, kwashiorkor) there were patients with low and with "normal" selenium values (taking the values of healthy German children as normal). Hair selenium values were not different between marasmic Sudanese children and healthy German children, probably due to reduced hair growth in malnourished children. Plasma glutathione peroxidase activity was reduced concomitantly with plasma selenium in the patients with protein-calorie malnutrition. There was a good correlation between plasma selenium and plasma glutathione peroxidase activity. A follow-up study showed that plasma selenium decreased during rehabilitation in those patients who had a "normal" value before treatment. This is probably due to the low selenium content of the two dietary formulae used, which contained 18 and 25 micrograms/L Se of formula,. It remains questionable whether the low selenium states and low selenium intake exhibit a healthy risk inhibiting further rehabilitation of the patients with severe protein-calorie malnutrition.
