Should insulin resistance be screened in lean hirsute women?

Abstract

The role of insulin resistance (IR) is well-documented in obese women with polycystic ovary syndrome (PCOS). Controversies exist concerning the presence of IR in idiopathic hirsutism (IH) or if it is a manifestation of high body mass index (BMI). We aimed to investigate the presence/absence of IR in lean hirsute women. One-hundred fifty-one lean women with hirsutism [96 PCOS (group 1) and 55 IH (group 2)] and 58 age-and BMI-matched healthy controls (group 3) were recruited in the study (mean age 25.21?±?6.1 versus 26.26?±?4.6years; BMI 21.79?±?1.7 versus 22.02?±?2.2?kg/m², respectively). Significantly higher insulin and HOMA-IR, and significantly lower fasting glucose insulin ratio (FGIR), quantitative insulin sensitivity check index (QUICKI), reciprocal insulin, and Raynaud index were detected in groups 1 and 2 than in group 3 (p?<?0.05). These IR indices were similar between groups 1 and 2. The number of patients with IR (HOMA-IR?>?2, FGIR?<?7.2, or QUICKI?<?0.357) was significantly higher in groups 1 and 2 than in group 3, but was similar between groups 1 and 2. A higher frequency of IR occurs in lean hirsute women regardless of they having PCOS or IH. IR may contribute to aetiopathogenesis of IH, or may cause some metabolic abnormalities in these patients.     

Evaluation of insulin resistance and metabolic syndrome in patients with polycystic ovary syndrome

Aim.?Polycystic ovary syndrome (PCOS) is associated with the clustering of states including insulin resistance (IR), obesity, elevated blood pressure, and dyslipidemia that are termed as metabolic syndrome (MBS). This study was designed to assess the differences between homeostatic model assessment (HOMA) values in PCOS and healthy women.

Methods.?In a case–control study, 55 women with PCOS and 59 women with normal cycles (control group) aged 15–40 years old were evaluated. In all the subjects (after obtaining written informed consent), blood pressure, body weight, height, body mass index (BMI), waist /hip ratio(WHR) and fasting blood glucose (FBG), triglycerides (TG), HDL, C-peptide, insulin, HOMA Index, and FGIR (fasting glucose to insulin ratio) were measured.

Results.?In this study, the prevalence of MBS was significantly higher in PCOS group compared with the control group (p = 0.028). There were no significant differences in age, waist/hip ratio, fasting glucose, insulin, and C-peptide levels between patients with PCOS and control group. Furthermore, the prevalence of impaired fasting glucose (IFG) and the mean of HOMA and FGIR did not differ significantly between PCOS and control group.

Conclusion.?Criteria of MBS are frequently present in young women with PCOS and may be more useful as a prognostic factor than IR indexes in this age group. We suggest evaluation of IR in older age women with PCOS.     

Comparison of two insulin sensitizers,metformin and myo-inositol,in women with polycystic ovary syndrome (PCOS)

Insulin resistance (IR) plays a pivotal role in PCOS. Insulin-sensitizer agents such as metformin and inositols have been shown to improve the endocrine and metabolic aspects of PCOS. The purpose of this study is to compare their effects on the clinical and metabolic features of the women with PCOS. Fifty PCOS women with IR and/or hyperinsulinemia were randomized to treatment with metformin (1500?mg/day) or myo-inositol (4?g/day). IR was defined as HOMA-IR >2.5, while hyperinsulinemia was defined as a value of AUC for insulin after a glucose load over the cutoff of our laboratory obtained in normal women. The Matsusa Index has been calculated. The women have been evaluated for insulin secretion, BMI, menstrual cycle length, acne and hirsutism, at baseline and after 6 months of therapy. The results obtained in both groups were similar. The insulin sensitivity improved in both treatment groups. The BMI significantly decreased and the menstrual cycle was normalized in about 50% of the women. No significant changes in acne and hirsutism were observed. The two insulin-sensitizers, metformin and myo-inositol, show to be useful in PCOS women in lowering BMI and ameliorating insulin sensitivity, and improving menstrual cycle without significant differences between the two treatments.

A pilot trial of metformin for insulin resistance and mood disturbances in adolescent and adult women with polycystic ovary syndrome

We examine the effects of metformin on insulin resistance (IR) and mood including in adolescent and adult women with polycystic ovary syndrome (PCOS). This trial was conducted in 19 adolescents (age ≤18 years) and 25 adult (age >18 years) women with PCOS. Anthropometric and measurements including, serum glucose, endocrine panel, and lipid profile were performed at baseline. IR was measured by Homeostasis Model Assessment IR (HOMA-IR). Anxiety and depression were measured by Beck’s Anxiety (BAI) and Depression Inventories (BDI-II). All tests were repeated after a 90-day treatment with metformin (1,500?mg/day). The severity of depression and anxiety decreased after 90-day treatment with metformin in women diagnosed with PCOS. The BAI scores were higher in adolescent group while BDI-II scores were higher in the adult group (p?=?.016). After 90-day metformin treatment, both BDI-II and BAI scores were decreased by 3.3 and 3.4, respectively (p?<?.001). Indicators of IR and obesity were improved with this therapy. Although the adolescents weighed lower than the adults, baseline HOMA-IR 5.5?±?1.7 was higher in this group than 4.4?±?1.2 in the adult women (p?=.022). The findings suggest that metformin decrease IR and improve mood both in adolescent and adult women with PCOS.     

Can adiponectin predict abnormal glucose tolerance in Thai women with polycystic ovary syndrome?

AIM: To evaluate whether adiponectin levels could predict abnormal glucose tolerance (AGT) in Thai women with polycystic ovary syndrome (PCOS). METHODS: A 75-g oral glucose tolerance test (OGTT) with fasting adiponectin and insulin (FI) blood sampling in 170 women with PCOS were performed consecutively. RESULTS: The prevalence of AGT was 45.9%. The body mass index (BMI), waist-to-hip ratio (WHR), fasting glucose and 2-h postload glucose were greater in the PCOS women with AGT than those without AGT (P<0.001). In addition, the PCOS women with AGT had more severe insulin resistance (IR) and lower adiponectin levels than those without AGT. However, the area under the ROC curve of adiponectin and insulin in predicting AGT was smaller than that of homeostatic model of IR (HOMA-IR) (P<0.01). The arbitrary cut-off values at 12 ug/mL of adiponectin, 10 microiu/mL of FI and 2 of HOMA-IR showed the sensitivity and specificity of 80.8% and 33.7%; 87.2% and 34.8%; and 89.7% and 31.5%, respectively. With these cut-off points, 46 (27.1%), 42 (24.7%) and 37 (21.8%) women, respectively, could be eliminated from performing OGTT. However, 15 (19.2%), 10 (12.8%) and 8 (10.3%), respectively, missed the diagnosis. In addition, with WHR and acanthosis nigricans adjustment, HOMA-IR, but not adiponectin, was a significant predictor of AGT. CONCLUSION: Our study demonstrated that almost half of the women with PCOS had AGT. Adiponectin levels were significantly lower in the PCOS women with AGT than those without AGT. However, adiponectin was not shown to be as strong a predictive factor and might not be such an excellent screening test as FI and HOMA-IR.

妊娠期糖尿病合并慢性高血压孕妇胰岛素抵抗水平及其对妊娠结局的影响

目的探讨妊娠期糖尿病(gestational diabetes mellitus,GDM)合并慢性高血压(chronic hypertension,CHT)孕妇的胰岛素抵抗(insulin resistance,IR)水平及其对妊娠结局的影响。方法本研究为回顾性病例对照研究。纳入2014年1月1日至2016年12月31日在北京大学第一医院规律产前检查并参加GDM一日门诊的单胎妊娠GDM孕妇2457例。回顾临床资料,采用稳态模型评估IR水平(homeostasis model assessment insulin resistance,HOMA-IR)。根据GDM孕妇是否合并CHT分为GDM合并CHT组(n=47)和GDM未合并CHT组(n=2410),并进一步根据孕前体重指数(body mass index,BMI)分为孕前BMI正常组(n=1590)及孕前超重和肥胖组(n=863)进行分层分析。采用两独立样本t检验、χ2检验分析组间孕妇年龄、HOMA-IR、孕前BMI、孕期增重、血糖等临床特征的差异。采用logistic回归模型分析HOMR-IR水平对妊娠结局的影响。结果合并CHT的GDM孕妇HOMA-IR(3.5±1.8与2.6±1.5,t=-3.290)、空腹血浆葡萄糖[(5.4±0.5)与(5.2±0.5)mmol/L,t=-3.005]、孕前BMI[(26.7±4.7)与(23.3±3.4)kg/m2,t=-4.842]以及发生子痫前期的比例[14.9%(7/47)与2.5%(61/2410),χ2=21.790]高于未合并CHT的GDM孕妇,但孕期增重少于未合并CHT者[(9.6±5.8)与(12.2±4.7)kg,t=3.790](P值均<0.01)。根据孕前BMI分层后,超重和肥胖孕妇中,GDM合并CHT组子痫前期的比例高于GDM未合并CHT组[15.2%(5/33)与4.2%(35/830),χ2=6.290,P=0.012],但HOMA-IR差异无统计学意义(P>0.05);而对于孕前BMI正常的孕妇,GDM合并CHT组HOMA-IR(3.0±1.5与2.3±1.2,t=-2.217)、空腹血浆葡萄糖[(5.4±0.5)与(5.1±0.5)mmol/L,t=-2.299]和子痫前期的比例[2/14与1.6%(26/1576),χ2=6.545]均高于未合并CHT组(P值均<0.05)。对于GDM合并CHT孕妇,HOMA-IR水平不会增加剖宫产、早产、大于胎龄儿、小于胎龄儿和巨大儿的发生风险(P值均>0.05)。控制年龄、空腹血浆葡萄糖、孕前BMI、孕期增重后,对于未合并CHT的GDM孕妇,HOMA-IR水平的增加会使早产的发生风险增加(OR=1.223,95%CI:1.093~1.369,P<0.001)。结论GDM合并CHT孕妇胰岛素抵抗程度更重,子痫前期的发病率更高,但其他不良妊娠结局的发生风险未见增加。     

Agreement among insulin sensitivity indexes on the diagnosis of insulin resistance in polycystic ovary syndrome and ovulatory women

OBJECTIVE: The objective was to compare agreement on the diagnosis of insulin resistance (IR) among insulin sensitivity indexes in both ovulatory women and those with polycystic ovary syndrome (PCOS). STUDY DESIGN: In an observational study, the 75-g oral glucose tolerance test was performed in 105 women with PCOS and 51 ovulatory women. The insulin sensitivity indexes used were insulin quantitative sensitivity check index (QUICKI), 1/homeostasis model assessment-insulin resistance (1/HOMA-IR), area under curve for insulin (AUC-I), and the Matsuda insulin sensitivity index (COMP). For the IR diagnosis we used cut-off values described in recent publications (insulin >12 microIU/ml, 1/HOMA-IR <0.47, QUICKI < or =0.333, AUC-I > or =7000 microIU/ml 120 min, and COMP <4.75. RESULTS: Excellent agreement was assessed among insulin, QUICKI, and 1/HOMA-IR. However, the rate of IR detected by these indexes in the PCOS group (44.8-51.4%) was lower than expected. New cut-offs were then determined based on COMP results. Using these values, 1/HOMA-IR and QUICKI showed excellent agreement (kappa=0.83) with COMP. CONCLUSION: The observed agreements among insulin, QUICKI and 1/HOMA-IR were higher than 93%. Therefore, clinicians may choose any of those obtaining similar results. For clinicians who prefer COMP, but are looking for a simpler test to detect IR in PCOS women, the use of QUICKI and 1/HOMA-IR with the new cut-offs seems reasonable.
