Blood glucose and serum insulin response in protein-energy malnutrition following nutritional rehabilitation
(Oxford University Press, 1998) B.K. Das; Jayanthy Ramesh; J.K. Agarwal; O.P. Mishra; R.P. Bhatt
Fifteen children with protein-energy malnutrition and eight healthy children between the ages of 6 months and 60 months were studied for blood glucose and serum insulin levels in the fasting state and 120 minutes following oral glucose load. The measurements were repeated after normalization of the body weight following 6 weeks of nutritional rehabilitation. The fasting blood glucose increased significantly in the post-treatment period and became comparable to the control value. The abnormal blood glucose response to oral glucose load also normalized. The serum insulin level rose significantly (p < 0.001) in the post-treatment period but failed to normalize. The response to oral glucose load was similar. The observed lower insulin response, despite normoglycemia, after 6 weeks of nutritional rehabilitation indicates persistence of hormonal imbalance which may need a longer duration of rehabilitation for full recovery.
Blood sugar and serum insulin response in protein-energy malnutrition
(Oxford University Press, 1998) B.K. Das; Jayanthy Ramesh; J.K. Agarwal; O.P. Mishra; R.P. Bhatt
Blood sugar and serum insulin levels in the fasting state and following an oral glucose load in children with protein-energy malnutrition (PEM) were studied. Twenty-nine children with PEM (15 marasmus, 7 kwashiorkor, and 7 marasmic kwashiorkor) and eight healthy children aged between 6 and 60 months were the subjects of the study. Fasting samples were collected after a 6 h fast. Post-glucose samples were collected after an oral glucose load of 1.75 g/kg. Serum insulin was estimated by radioimmunoassay and glucose by the glucose oxidase method. In malnourished children, the mean fasting blood glucose levels were significantly lower. Two hours following an oral glucose load, only marasmus and marasmic kwashiorkor patients showed significantly higher blood glucose levels. Similarly, the fasting serum insulin levels were significantly lower in malnourished children. Two hours after the oral glucose load, serum insulin levels increased significantly in malnourished children but fell well short of the control values. The insulin:glucose ratio was consistently low in all cases but was more marked in PEM patients, both in the basal state as well as after oral glucose loading.
