This study is aimed to determine the association of visceral adiposity index (VAI) with insulin resistance in adults with prediabetes. This cross-sectional study was done among 117 adults with newly detected prediabetes [m/f;23/94;mean ± SD: Age 36.30 ± 9.99 years, BMI 28.89 ± 4.35 kg/m<sup>2</sup>] based on American Diabetes Association 2018 criteria and 141 matched healthy controls [m/f: 28/113;mean ± SD: 35.30 ± 6.88 years, BMI 25.03 ± 4.58]. Waist circumference, body mass index, fasting triglyceride, HDL cholesterol, fasting blood glucose and insulin were measured in each group to calculate VAI and homeostatic model assessment of insulin resistance (HOMA-IR). People with prediabetes had significantly higher median value of VAI {3.08 (2.26) vs. 1.86 (2.31);p < 0.001} with higher frequency of high VAI (>1) (98.3% vs. 85.8%;p < 0.001) than the control population. HOMA-IR level was significantly higher in prediabetes with high VAI (cut-off of 2.64) than control with normal VAI [2.78 (2.22, 4.15) vs. 2.20 (1.53, 3.36);p = 0.002]. VAI was positively correlated with HOMA-IR in females with prediabetes (r = 0.299, p = 0.003). VAI had predictive association with prediabetes [OR (95% CI: 9.504 (2.173, 41.576);p = 0.03] and high insulin resistance (HOMA-IR ≥ 2.6) in females with prediabetes [OR (95% CI) = 3.50 (1.476, 8.297);p = 0.004] only. It could satisfactorily discriminate prediabetes in both sexes (male: AUC = 0.767, p = 0.001;female: AUC = 0.641, p < 0.001) and high insulin resistance in females with prediabetes (AUC = 0.641;p = 0.019) only. So, VAI was associated with prediabetes and insulin resistance only in females with prediabetes.</span> </div>展开更多

Nonalcoholic steatohepatitis(NASH) in children has been known since 1983. However, NASH diagnosed in childhood does not have a favorable outcome.The pathological characteristics of NASH are significantly different between children and adults. Nonalcoholic fatty liver disease(NAFLD)/NASH is accompanied by insulin resistance, which plays a pivotal role in its pathophysiology in both children and adults. In NASH,a "two-hit" model involving triglyceride accumulation(first hit) and liver damage(second hit) has been accepted. Insulin resistance was found to correlate with changes in fat levels; however, it did not correlate with fibrosis or NAFLD activity score in children. Therefore,insulin resistance may be important in the first hit.Because there is obvious familial clustering in NASH,genetic predisposition as well as environmental factors including diet might be the second hit of NAFLD/NASH.展开更多

文摘目的:探讨血清及胆汁中视黄醇结合蛋白4(retinol binding protein 4,RBP4)的浓度与胰岛素抵抗、血脂异常、胆汁胆固醇饱和指数(cholesterol saturation index,CSI)之间的关系。方法:将住院手术治疗胆囊结石的患者随机分为糖尿病组和对照组,每组30例。采用ELISA法检测糖尿病组和对照组血清及胆汁中RBP4的浓度,酶比色法测定胆汁胆固醇、胆汁酸和磷脂的含量,采用Carey表计算胆汁CSI,分析血清及胆汁中RBP4水平与各项指标的相关性,并对相关指标进行多元线性回归分析。结果:糖尿病组血清及胆汁中RBP4的浓度均显著高于对照组(均P<0.01)。两组血清总胆汁酸(total bile acid,TBA),TG,HDL,以及胆汁TBA,TC,磷脂及CSI之间的差异均无统计学意义(均P>0.05)。糖尿病组血清TC,LDL,空腹血糖(fasting blood glucose,FBG)、空腹胰岛素(fasting insulin,FINS)以及稳态模型评估的胰岛素抵抗指数(homeostasis model assessment for insulin resistance index,HOMA-IR)均高于对照组,差异均有统计学意义(均P<0.05)。校正年龄影响后的偏相关分析表明:胆汁RBP4与体质量指数(body mass index,BMI),腰围(waist circumference,WC),空腹血清胰岛素(fast serum insulin,FINS),FBG,TC,LDL,HOMA-IR呈正相关(分别r=0.283,0.405,0.685,0.667,0.553,0.424,0.735);血清RBP4与WC,FINS,FBG,TC,LDL,HOMA-IR呈正相关(分别r=0.317,0.734,0.609,0.528,0.386,0.751);逐步法多元线性回归分析表明HOMA-IR,BMI,WC与胆汁RBP4水平独立相关(回归方程如下:Y胆汁RBP4=2.372XHOMA-IR+0.420XBMI+0.178XWC-26.813);HOMA-IR,WC与血清RBP4水平独立相关(回归方程如下:Y血清RBP4=2.832XHOMA-IR+0.235XWC-20.128),HOMA-IR与RBP4的相关性最强。结论:糖尿病组血清及胆汁中RBP4的浓度显著高于对照组;HOMA-IR,BMI,WC与胆汁RBP4呈独立相关;HOMA-IR,WC与血清RBP4呈独立相关;HOMA-IR与RBP4的相关性最强。RBP4可能在2型糖尿病合并胆囊结石的发展过程中起着重要作用。
