The lipid composition of plasma, including total HDL and LDL cholesterol, t
riglycerides, apo AI, apo B, and fatty acids was investigated in 29 malnour
ished Moroccan children in two groups: 12 children with mild PCM, and 17 wi
th severe PCM. Normally nourished children from the same area (n = 15) serv
ed as controls. The severe malnourished children showed a significant reduc
tion of apo AI, total and LDL cholesterol, and an increase in the levels of
triglycerides. Furthermore, these children showed a decrease in the satura
ted fatty acids myristic and stearic acid, and a similar decrease in the es
sential fatty acid (EFA) metabolites, especially eicosatrienoic acid, arach
idonic acid, and eicosapentaenoic acid, with an increase in the oleic and c
isvaccenic monounsaturated fatty acids, In contrast, the PCM group showed o
nly an increase of docosatetraenoic and docosapentaenoic, with an associate
d decrease in myristic acid and palmitic acid, On the other hand, the index
es of Delta 9 desaturase and elongase n-3 and n-6 were increased, and this
was found to be related to the severity of the malnutrition. These results
suggest that the severity of malnutrition is associated with an increase of
desaturation and elongation of PUFA, EFA deficiency and/or peroxidation. (
