BACKGROUND: Metabolic disorder of blood lipid can be observed in the non-diabetic first-degree relatives.OBJECTIVE: To explore the relationship between the level of blood lipid and insulin resistance in members of type 2 diabetic pedigrees.DESIGN: A retrospective case control study of the non-diabetic first-degree relatives of type 2 diabetic families.SETTING: The department of endocrinology of a university hospital.PARTICIPANTS: This study was carried out in the Department of Endocrinology of the First Affiliated Hospital of Chongqing Medical College from June to November 1999. A total of 125 non-diabetic first-degree relatives of type 2 diabetic pedigrees in Chongqing were recruited and divided into hyperlipemia group and normal control group according to their blood lipid level.INTERVENTIONS: Body height, body mass and blood pressure of all the subjects were measured. Their cubital venous blood samples were also obtained for determination of the levels of fasting plasma glucose (FPG), fasting insulin(FINS), fasting C-peptide(FCP), triacylglycerol(TG), total cholesterol(TC), low-density lipoprotein-cholesterol (LDL-C), and high-density lipoprotein-cholesterol (HDL-C).homeostasis model assessment insulin resistance(HOMA-IR) between the two groups.RESULTS: The level of FINS was markedly higher in the hyperlipemia group [(12.92 ±5.26) μU/L] than in the control group[(9.15 ±4.66) μU/L]( t = 2. 17, P < 0.05) . HOMA-IR was also significantly higher in the hyperlipemia group [ (2.94 ± 1.25 ) ] than in the control group [ (2.01 ± 0.94) ]( t = 2.70, P < 0.01 ) . In the hyperlipemia group, HOMA-IR was positively correlated with TC, TG and LDL-C ( r = 0. 34, 0. 78, 0.42), with TG most closely correlated( r = 0. 78, P < 0. 01), while HOMA-IR had no significant relation with HDL-C ( P > 0.05).CONCLUSION: There is a close correlation between lipid metabolic disorder and insulin resistance in the high-risk diabetic group.

Objective To investigate the change of serum non-esterified fatty acid (NEFA) level in nondiabetic first-degree relatives of type 2 diabetics, and to explore the related factors in the change.MethodsSerum lipid profile, plasma glucose and insulin levels were measured in 186 type 2 diabetic patients, 565 nondiabetic first-degree relatives of type 2 diabetics and 149 normal controls. Results (1) The fasting NEFA level in first-degree relatives was significantly lower than that of type 2 diabetic patients [(0.53±0.28 vs 0.63±0.31) mmol/L,P＜0.01]and HOMA-IR was significantly higher than that of normal controls (0.98±0.51 vs 0.89±0.47,P＜0.01). (2) The fasting NEFA level in the first-degree relatives with higher body mass index (BMI), plasma glucose or area under curve of glucose concentration (AUCglu) was higher than that in those with lower BMI, plasma glucose , blood pressure or AUCglu (all P＜0.05). (3) NEFA showed significantly positive correlations with BMI, systolic blood pressure, diastolic blood pressure (DBP), AUCglu in the first-degree relatives by correlative analysis (r=0.12, r=0.148, r=0.21 and r=0.281 respectively, all P＜0.05). Stepwise linear regression analysis showed that DBP, AUCglu and age were the independent risk factors of NEFA (all P＜0.01). Conclusion Insulin resistance exists in nondiabetic first-degree relatives of type 2 diabetics, which seems to be related to elevated NEFA levels.
