Abstract
Plasma selenium (Se), haemoglobin (Hb) and packed cell volume (PCV) were measured in 53 malnourished Sudanese children, age 6-36 months, and 11 children who had tuberculosis. Twelve healthy well-nourished children served as controls. The mean (± SD) plasma Se (mg/kg) was 0.05 (0.036), 0.070 (0.040), 0.063 (0.015), 0.73 (0.012), 0.082 (0.014) in children with kwashiorkor/marasmic kwashiorkor (oedematous group), marasmus, tuberculosis and healthy controls. The mean Se level in the various groups showed a significant difference (p < 0.002). Whereas the oedematous group differed significantly from the rest, there was no difference between the means of the marasmic, underweight, tuberculous patients and controls. The mean plasma albumin ( ± SD) in oedematous group was 19.6 (6.6) g/1 and ranged between 22.6 (5.0) and 33.1 (3.0) in the other groups. A significant positive correlation was found between plasma Se level, albumin, Hb and PCV (respectively, r = 0.46, p < 0.0001; r = 0.37, p < 0.001; r = 0.36, p < 0.002).
