RESUMEN
Objective To explore the correlation of serum thyroid hormones with glucose and lipid metabolism in children with type 1 diabetes (T1DM) whose thyroid functions with normal.Methods 50 T1DM and 71 healthy children were enrolled in our study.Their blood glucose,lipid,HbA1c and thyroid functions were determined.Results Compared with the control group,patients with T1DM had higher low density lipoproteincholesterol (LDL-C),triglyceride(TG),fasting blood glucose (FBG) and HbA1c while with lower high density lipoprotein-cholesterol (HDL-C),thyroid Stimulating Hormone (TSH),and free triiodothyronine (FT3) (P＜0.05).In children with T1DM,TSH was positively correlated with LDL-C (r=0.175,P=0.034),total cholesterol (TC)(r=0.187,P=0.009) and TG(r=0.206,P=0.005) while negatively correlated with FBG(r=-0.187,P=O.018) and HbA1c (r=-0.264,P＜0.001).FT3 was negatively correlated with TG (r=-0.185,P=O.012),FBG (r=-0.193,P=O.O07) and HbA1c 0=-0215,P=0.002).But there were no correlations of FT4 with glucose or lipid metabolism.Conclusion TSH and FT3 are significantly correlated with glucose and lipid metabolism in children with T1DM.
