Objective: To investigate the relation of circulating four adipokines (apelin, vaspin, visfatin, adiponectin) with markers of insulin sensitivity in large for gestational age (LGA) infants.
Patients and methods: Forty LGA infants (20 LGA born from diabetic mothers and 20 LGA born from nondiabetic mothers) and 34 appropriate for gestational age (AGA) infants were recruited. Hyperinsulinism and insulin resistance was evaluated using the homeostasis model assessment (HOMA-IR), fasting glucose-to-insulin ratio (FGIR), quantitative insulin-sensitivity check index (QUICK-I) from fasting samples. Plasma adiponectin and vaspin levels were determined by radioimmunoassay. Determination of visfatin and apelin levels was performed by enzyme immunoassay.
Results: HOMA-IR, apelin and visfatin levels (p <0.001, p <0.001, p <0.001, respectively) were significantly elevated and adiponectin levels, FGIR and QUICK-I values. (p < 0.001, p < 0.001, p < 0.05, respectively) were significantly lower in the LGA group. Vaspin levels were higher in the LGA group than AGA neonates without a significance. The LGA infants with diabetic mother had significantly higher visfatin, apelin, HOMA-IR values, fasting insulin levels and significantly lower adiponectin, FGIR, QUICK-I values. Apelin and visfatin were correlated positively, and adiponectin was correlated negatively with birthweight, HOMA-IR values and fasting insulin levels.
Conclusion: Based on the findings of this study, it is too difficult to explain relation between birthweight and these adipocytokines, but findings of high insulin. HOMA-IR, visfatin, apelin and low adiponectin levels in the LGA neonates showed that these adipocytokines can be used as a good predictor for metabolic syndrome.
