Homeostatic model assessment (HOMA) is commonly used as a parameter of the severity of insulin resistance. <strong>Aims:</strong> To determine indices of insulin resistance (IR) and <em>β</em>-cell function in gestational diabetes mellitus (GDM). <strong>Methods:</strong> This cross sectional study was conducted from March 2017 to September 2018 at Department of Endocrinology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh. The study was performed with 41 GDM and equal number of pregnant women with normal glucose tolerance (NGT) diagnosed on basis of WHO criterion-2013 during 24 - 40 weeks of gestation. Serum glucose was measured by glucose oxidase method and fasting serum insulin was measured by chemiluminescent immunoassay. Equations of homeostatic model assessment (HOMA) were used to calculate insulin indices like-insulin resistance (HOMA-IR), <em>β</em>-cell function (HOMA-B) and insulin sensitivity (HOMA-%S). Data were analyzed and compared by statistical tests. <strong>Results: </strong>A total of eighty-two (82) subjects [41 women with GDM (age: 28.29 ± 3.79 years, BMI: 27.16 ± 4.13 kg/m2) and 41 women with NGT (age: 26.22 ± 5.13 years, BMI: 25.27 ± 3.01 kg/m2)] were included in this study. It was observed that GDM women were significantly older (p = 0.041) and had significantly higher BMI (p = 0.020) than pregnant women with NGT. The GDM group had significantly higher IR as indicated by higher fasting insulin value [GDM vs. NGT;10.19 (7.71 - 13.34) vs. 6.88 (5.88 - 8.47) μIU/ml, median (IQR);p = 0.001] and HOMA-IR [GDM vs. NGT;2.31 (1.73 - 3.15) vs. 1.42 (1.15 - 1.76), median (IQR);p < 0.001], poor <em>β</em>-cell secretory capacity [GDM vs. NGT;HOMA-B: 112.63 (83.52 - 143.93) vs. 128.60 (108.77 - 157.58), median (IQR);p = 0.04] and low insulin sensitivity [GDM vs. NGT;HOMA-%S: 43.29 (31.77 - 57.98) vs. 70.42 (56.86 - 86.59), median (IQR);p < 0.001]. Conclusions: GDM is associated with both insulin resistance and inadequate insulin secretion.展开更多

HOMA-IR was accepted to determine the insulin sensitivity as a valuable standard. In this study, we evaluated the association between HOMA-IR (homeostasis model assessment of insulin resistance) and vascular endothelial dysfunction, as assessed by endothelium- dependent flow-mediated dilatation (FMD) and nitroglycerin-mediated dilatation (NMD), in type 2 Diabetic (DM) patients. Material and Methods: Eighty four (84) consecutive out-patients were enrolled. HOMA-IR was calculated as fasting insulin (μU/ml) multiplied by fasting plasma glucose (FPG) (mg/dl) and divided by 405. The ultrasound method for measuring FMD and NMD has been used. Out of 84 patients, 42 patients were in control group and 42 patients were in diabetic group, which were further subdivided into two groups based on HOMA-IR > 3.0 and above was considered as Group I and HOMA IR < 3.0 and below was considered as Group II. Fasting Plasma Glucose (mmol/dl) (7.74 ± 2.56, 6.81 ± 1.9, p < 0.001) and Fasting Insulin (μU/dl) (13.26 ± 8.09, 6.65 ± 2.36, p < 0.001) were statistically significant in Group I. The baseline mean FMD in controls and cases (Group I and Group II) was 15.36 ± 9.56, 4.15 ± 2.29, 12.21 ± 6.24 (p < 0.001) respectively. By logistic regression analysis the factors which were effective on FMD percentage change (<5.5%) in Group I were BMI (p < 0.02), plasma Insulin (p < 0.04) and triglycerides (p < 0.02). There was a negative co-relation for FMD, NMD and HOMA-IR. Discussion: We conclude that increased HOMA-IR in hyperglycaemic patients is associated with severe endothelial dysfunction which is the marker of the atherosclerosis. Thus the measurement of endothelial vasomotor function which is a comprehensive analysis of atherosclerotic burden may provide a better predictive value of future cardiovascular events than the analysis of each of the traditional risk factors alone.展开更多

文摘目的:观察外科感染病人胰岛素抵抗(IR)状况,研究其临床意义,并探讨如何应用临床常用参数评价感染病人的胰岛素敏感性(ISI)。方法:检测外科不同病情严重程度感染患者空腹血糖(FBG)、空腹胰岛素(FINS),以正常健康人为对照,利用稳态模式评估法(HOMA)计算胰岛素抵抗指数(HOMA-IR)、胰岛素分泌指数(HOMA-)β,观察外科感染病人ISI,并且分析不同病情严重程度和不同病种感染病人之间ISI是否存在显著差异。使用多元线性回归方程和多因素Logistic进行多因素分析,应用临床常用的参数评价感染ISI状况。结果:①外科感染病人中IR发生率为92.06%(58/63)。不同病种,包括急性重症胰腺炎病人、肠瘘病人和急性胆管炎病人,不论HOMA-IRl、gHOMA-IR还是HOMA-β均无显著差异(P>0.05)。②按病情严重度和最终预后对病人分组:SIRS病人IR发生率为20%(7/35),脓毒症病人IR发生率为86.20%(25/29),脓毒性休克和MODS组病人IR发生率为95.83%(23/24),死亡组病人IR发生率为100%(10/10)。各组间IR有显著差异(P<0.01),而HOMA-β无显著差异(P>0.05)。③临床各常用参数与ISI之间相关性分析显示器官功能衰竭连续评分(sequential organ failure assessment,SOFA)、FINS、FBG、转铁蛋白、脓毒症评分(sepsis scores,SS)评分、C-反应蛋白(CRP)、前白蛋白、三酰甘油(TG)和胰岛素用量/葡萄糖用量与ISI呈独立正相关,方程的R2为0.900。各临床参数对IR的多因素Logistic回归显示FINS、FBG、低密度脂蛋白(LDL)和SOFA进入模型,其中FBG和FINS与IR的回归关系更明显,而其他临床指标与IR未显示有意义的回归关系。结论:①外科感染病人中普遍存在IR,并与引起感染的病种无关;②IR与疾病严重程度最终预后密切相关,可作为判断危重病人病情转归和预后的预警指标;③临床常用参数SOFA评分、FINS、FBG、转铁蛋白、SS评分、CRP、前白蛋白和TG与感染病人ISI的关系更为密切。
