RESUMEN
Objective To determine the association of acanthosis nigricans(AN) with values for estimating insulin resistance and adipocytokine levels in simple obese children. Methods These subjects concluded 38 simple obese children. AN was present in 17 of 38 children. Height, weight and abdominal circumference were recorded and fasting blood sample was obtained for measurement of blood glucose, plasma insulin, leptin, and plasminogen activator inhibitor 1 (PAI-1) levels which were known as the risk factors of cardiovascular disease. We obtained homeostasis model assessment insulin resistance index (HOMA-R) by fasting blood glucose and plasma insulin levels. Results The severity of obesity, abdominal circumference, fasting insulin levels and HOMA-R were significantly higher in obese children to AN compared to those without AN. There was the tendency that children with AN had higher levels of leptin and PAI-1 compared to children without AN. Conclusions These results suggest that obese children with AN may have a risk of cardiovascular disease as well as type 2 diabetes mellitus.
