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.
选取了24例典型消瘦症和夸希奥科病患者以及同等数量的健康对照者进行研究。他们的血清氨基酸模式分析显示,正常个体空腹样本中谷氨酸与丙氨酸的平均比值为0.33,而在夸希奥科病患者中该比值为9.3,在消瘦症患者中为1.6。正常对照者、夸希奥科病患者和消瘦症患者之间的这种差异具有统计学意义。这一观察结果可能解释了饮食相似的儿童发生消瘦症和夸希奥科病的原因。基于目前的观察结果推测,在夸希奥科病中,在氨基供体谷氨酸存在的情况下,丙酮酸向丙氨酸的转化不能正常进行,导致谷氨酸积累和丙氨酸水平降低。因此,消瘦症和夸希奥科病的发生可能不仅与饮食不足有关,还与转氨酶功能有关。这可能源于遗传。
