Aims
The aim was to examine associations of insulin resistance and beta cell dysfunction with macrosomia in Chinese women with gestational diabetes mellitus (GDM).Methods
We performed a secondary analysis of 923 women with GDM enrolled in a randomized controlled trial in 2010–2012 in Tianjin, China. Insulin resistance and beta-cell function were estimated using Homeostasis model assessment. Binary logistic regression was used to obtain adjusted odds ratios (ORs) and 95% confidence intervals (CIs). A two-step adjustment scheme was used to control for effects of potential confounders.Results
A total of 138 women (16.5%) had excessive weight gain, 127 (7.3%) had macrosomia and 150 (16.3%) had a large for gestational age (LGA) infant. Compared to women in bottom tertile of insulin resistance, women in upper tertile had increased risk of excessive weight gain (OR: 4.32, 95%CI: 1.95–9.62), macrosomia and LGA (OR: 2.61, 95%CI: 1.20–5.69; 2.75, 95%CI: 1.35–5.62, respectively). The observed overall effects were mainly due to their large effect sizes among women with normal pre-pregnancy body weight. However, beta cell function was not found to be associated with either of them.Conclusions
Increased insulin resistance during pregnancy was associated with excessive weight gain, macrosomia and LGA in Chinese women with GDM. 相似文献3.
Aims/hypothesis Our aim was to define the level of glycaemia at which pancreatic insulin secretion, particularly first-phase insulin release, begins to decline.Methods Plasma glucose and insulin concentrations were measured during an IVGTT in 553 men with non-diabetic fasting plasma glucose concentrations. In 466 of the men C-peptide was also estimated. IVGTT insulin secretion in first and late phases was assessed by: (i) the circulating insulin response; (ii) population parameter deconvolution analysis of plasma C-peptide concentrations; and (iii) a combined model utilising both insulin and C-peptide concentrations. Measurements of insulin sensitivity and elimination were also derived by modelling analysis.Results As fasting plasma glucose (FPG) increased, IVGTT first-phase insulin secretion declined by 73%, 71% and 68% for the three methods respectively. The FPG values at which this decline began, determined by change point regression, were 4.97, 5.16 and 5.42 mmol/l respectively. The sensitivity of late-phase insulin secretion to glucose declined at FPG concentrations above 6.0 mmol/l. Insulin elimination, but not insulin sensitivity, varied with FPG.Conclusions/interpretation The range of FPG over which progressive loss of the first-phase response begins may be as low as 5.0 to 5.4 mmol/l, with late-phase insulin responses declining at FPG concentrations above 6.0 mmol/l.Abbreviations f fractional hepatic insulin throughput - FPG fasting plasma glucose - FSD fractional standard deviation - kc the plasma C-peptide elimination constant - ki the plasma insulin elimination constant - MFG mean fasting glucose - SG minimal model glucose effectiveness - SI minimal model insulin sensitivity In the course of this work, our colleague and co-author James Jeffs died unexpectedly after a short illness.

Although adiponectin levels are associated with obesity and insulin insensitivity, the role of adiponectin in the progression
to diabetes in non-obese subjects is unclear. Therefore, 289 women aged 50–80 years without previous history of diabetes or
impaired glucose tolerance (IGT) were studied. They were classified as normal glucose tolerance (NGT), IGT or diabetes based
on WHO criteria. Insulin sensitivity (S) and beta cell function (B) indices were calculated using homeostasis model assessment
(HOMA). In obese women with BMI ≥ 25 kg/m2 (n = 161), there were declines in HOMA-%S (P < 0.001), HOMA-%B (P < 0.05) and circulating adiponectin (P < 0.001) across glucose tolerance status. In non-obese women with BMI < 25 kg/m2 (n = 128), there was no significant change in HOMA-%S in women with IGT and diabetes as compared to women with NGT. However,
HOMA-%B (P < 0.05) and serum adiponectin levels (P < 0.001) were significantly decreased across glucose tolerance. Serum adiponectin levels were correlated to HOMA-%S in both
obese and non-obese women while negative correlations between circulating adiponectin and HOMA-%B were demonstrated only in
obese women. We have demonstrated in the present study the predominant role of beta cell dysfunction as compared to that of
insulin resistance in the deterioration of glucose tolerance in non-obese women. Circulating adiponectin appears to be inversely
related to beta cell dysfunction in addition to insulin resistance only in obese women. 相似文献

AimTo evaluate the association between elevated serum transaminase levels and insulin resistance (IR) in a population of healthy individuals.MethodsWe define IR with a cut-off point of homeostatic model assessment (HOMA-IR) ≥ 3.8. For aspartate aminotransferase (AST), we consider elevated values >30 U/L in women and values >36 U/L in men. For alanine aminotransferase (ALT), we consider elevated values >30 U/L in women and values >40 U/L in men. We performed a crude and adjusted generalized linear model from Poisson family with robust variance, in order to evaluate the association between elevated serum transaminase levels and IR. The associations were presented as prevalence ratio (PR) with their respective 95% confidence intervals (95% CI).ResultsWe included 261 participants in the study. The median age was 39 years (31–45) and 23.7% of the participants were men. The prevalence of elevated serum transaminase for AST and ALT were, 13.8% and 26.1%, respectively. The prevalence of IR was 34.1%. In the crude analysis we found statistical significance between elevated AST and ALT with IR (PR = 3.18; 95% CI: 2.33–4.34 and PR = 2.44; 95% CI: 1.88–3.30; respectively). However, in the multivariate analysis, the association only remained statistically significance with ALT, but lost its significance with AST, PR = 1.90; CI 95%: 1.31–2.77 and a PR = 1.23; CI 95%: 0.93–1.61; respectively.ConclusionElevated serum levels of ALT were associated with insulin resistance. ALT could be used in clinical practice as an additional tool to assess IR in apparently healthy people. 相似文献

脂联素与炎症及胰岛素抵抗关系的研究进展 总被引:5,自引:0,他引:5
胰岛素抵抗是由免疫系统介导的慢性、非特异性炎症过程。而脂联素具有抗炎、促炎的双重作用。其与炎症因子的相互作用可能是脂联素增强胰岛素敏感性的机制之一,也可能是胰岛素抵抗时低脂联素血症的原因。对脂联素与炎症、胰岛素抵抗关系的研究可为胰岛素抵抗的治疗提供新的思路。 相似文献

Leukaraiosis and a higher level of pulse pressure are well-recognized as associated with cardiovascular disease, vascular angiopathy, and geriatric syndrome. A cross-sectional study was conducted to examine the relation between pulse pressure and leukoaraiosis based on brain magnetic resonance imaging (MRI) scans in the apparently healthy elderly (147 men aged 60-84 years and 89 women aged 60-82 years). The odds ratios (OR) and 95% confidence interval (CI) for leukoaraiosis were calculated using multivariate logistic regression analyses according to each quartile of pulse pressure. The percentage of leukoaraiosis gradually increased in accordance with pulse pressure quartiles: 5.1%, 8.6%, 16.1%, and 26.2% for men, and 4.5%, 8.7%, 13.0%, and 23.8% for women. In comparison with subjects in the lowest quartile, the OR (95%CI) for leukoaraiosis in the highest quartile was 6.80 (1.20-38.45) in men after adjusting for age, body mass index, fasting plasma glucose, HDL-cholesterol, triglyceride (TG), smoking status, and current drinking. However, the relationship was not evident in women after adjusting for the same co-variables. In conclusion, pulse pressure was found to be independently associated with leukoaraiosis regardless of classical cardiovascular risk factors in elderly men. 相似文献

Hyperuricemia is associated with cardiovascular disease, but the relationship between uric acid (UA) and pulse pressure (PP) is unclear. Therefore, the present study assesses the relationship between UA and PP among Korean adults. Data from 6,310 subjects (2,800 men and 3,510 women) in the seventh Korean National Health and Nutrition Examination Survey (2016) were analyzed. After adjusting for related variables, the odds ratios (ORs) of hyperuricemia (UA ≥ 7.0 mg/dL in men or ≥ 6.0 mg/dL in women) in the high PP group (PP > 65.0 mmHg) in overall populations (OR, 1.563; 95% confidence interval [CI], 1.144–2.136) and women (OR, 1.631; 95% CI, 1.046–2.544) were significantly higher than those in normal PP, but not in men (OR, 1.309; 95% CI, 0.840–2.040). In conclusion, uric acid was positively associated with pulse pressure in women, but not in men. 相似文献

Aims/hypothesis Antioxidants have been shown to ameliorate lipid-induced impairment of insulin action and beta cell function, both in vitro
and in animal studies. The aim of the present study was to examine the effects of two orally administered antioxidants, N-acetylcysteine (NAC) and taurine (TAU), on lipotoxicity in humans.
Methods Nine non-diabetic men, who were either overweight or obese, underwent three studies each, 4–6 weeks apart, in random order:
(1) i.v. infusion of saline for 48 h (SAL); (2) i.v. infusion of Intralipid and heparin for 48 h to mimic chronic elevation
of plasma NEFA (IH); and (3) IH infusion for 48 h with concurrent oral NAC (IH+NAC). Six men underwent similar studies except
for study 3, where instead of NAC they received a 2 week pretreatment with oral TAU (IH+TAU).
Results For both the NAC and TAU studies, a 48 h IH infusion alone without antioxidant impaired insulin sensitivity (S
I, 63% and 62% of SAL in NAC and TAU studies, respectively) and beta cell function, as evidenced by a reduction in disposition
index (DI, 55% and 54% of SAL in NAC and TAU studies, respectively). NAC failed to prevent the lipid-induced increase in levels
of the plasma oxidative stress marker malondialdehyde and did not prevent the lipid-induced reduction in S
I or DI, whereas TAU completely prevented the rise in malondialdehyde and decreased 4-hydroxynonenal, and significantly improved
S
I (91% of SAL) and DI (81% of SAL).
Conclusions/interpretation Oral TAU ameliorates lipid-induced functional beta cell decompensation and insulin resistance in humans, possibly by reducing
oxidative stress.

Aim of the studyBariatric surgery causes profound improvement in metabolic parameters by increasing plasma glucagon like peptide - 1 (GLP-1) level even few weeks after surgery. GLP-1 analogues can cause calcitonin secreting medullary thyroid carcinoma in animals. The studies relating to the mechanisms that underlie these changes are few. The objectives of the study were to measure the change in insulin resistance, beta cell function, GLP-1 and calcitonin levels before and 2 weeks after bariatric surgery.MethodsPatients above 18 years of age who underwent either laparoscopic sleeve gastrectomy or Roux-en Y gastric bypass were recruited into the study. Measured indices were homeostatic model assessment 2 for insulin resistance (HOMA2-IR), an index for hepatic insulin resistance; Matsuda index, an index of whole body insulin sensitivity; and insulin secretion and sensitivity index (ISSI-2), a marker of beta cell secretion.ResultsTwenty eight patients completed the study. HOMA2-IR was lower (2.72 ± 1.28 vs. 2.04 ± 0.9; P = 0.001) and ISSI-2 was higher (0.80 (0.51–1.26) vs. 1.04 (0.56–1.38); P = 0.019) at 2 weeks after surgery compared to baseline. Matsuda index also improved after surgery but was not statistically significant (2.02 (1.1–2.94) vs. 2.84 (1.56–4.12); P = 0.078). Fasting GLP-1 and calcitonin levels did not change while both peak GLP-1, and area under curve for GLP-1 were higher after surgery.ConclusionsAt 2 weeks following bariatric surgery, hepatic insulin resistance decreased while beta cell function improved due to increase in postprandial GLP-1 level without any change in fasting calcitonin levels. 相似文献

This study was to explore the relationship of serum BMP7 with insulin secretion and metabolic parameters in non-diabetic individuals. Serum BMP7 concentrations positively correlated with HOMA2-%B (insulin secretion index) and fasting insulin. Our findings suggested that BMP7 may stimulate insulin secretion and improve islet cell function in humans. 相似文献

Impaired beta cell glucose sensitivity and whole-body insulin sensitivity as predictors of hyperglycaemia in non-diabetic subjects 总被引:2,自引:0,他引:2
Aims/hypothesis The aim of this prospective study was to investigate predictors of deteriorating glucose tolerance in subjects of British
extraction.
Methods A total of 156 non-diabetic subjects (86 with a family history of type 2 diabetes) underwent a 75-g OGTT and anthropometric
assessment at baseline and 5 years later. Pancreatic beta cell function and whole-body insulin sensitivity were studied by
model assessment. Subjects were classified as progressors if glucose tolerance moved one or more steps from normal, impaired
fasting glucose, impaired glucose tolerance and diabetes over the follow-up period.
Results At baseline, the progressors (n=22) had increased adiposity and a higher proportion of familial diabetes and abnormal glucose tolerance than non-progressors.
Baseline pancreatic beta cell sensitivity to changes in glucose (p<0.02) and whole-body insulin sensitivity (p<0.0001) were decreased in the progressors. Logistic regression revealed that baseline and follow-up changes in beta cell
glucose sensitivity and insulin sensitivity, rather than the classical clinical predictors (adiposity, familial diabetes and
glucose levels), were the key independent predictors of progression (explaining over 50% of the progression).
Conclusions/interpretation Impaired pancreatic beta cell glucose sensing and whole-body insulin sensitivity predict progression to hyperglycaemia. Strikingly,
these pathophysiological changes override the importance of the clinical risk factors and highlight potential metabolic targets
for prevention strategies.
