Serum amino acids and genesis of protein energy malnutrition.
Twenty four patients of classical marasmus and kwashiorkor along with equal number of healthy controls were selected for the study. Their serum amino acid patterns analysis revealed a mean ratio of glutamate to alanine in fasting samples of normal individuals to be 0.33, while it as 9.3 in kwashiorkor and 1.6 in marasmus. This differences in controls, kwashiorkor and marasmus was statistically significant. This observation may explain evolution of marasmus and kwashiorkor in children with similar diets. On the basis of the present observation it is postulated that in kwashiorkor, the conversion of pyruvate to alanine in presence of glutamate, an aminogroup donor does not proceed normally, resulting in accumulation of glutamate and low alanine. Thus the development of marasmus and kwashiorkor may not be related to dietary inadequacy alone but also to the transaminase function. This could be genetic in origin.
