Relationships between serum uric acid,adiponectin and arterial stiffness in postmenopausal women

Objectives

Cardiovascular disease (CVD) is a leading cause of death in postmenopausal women. Elevated serum uric acid levels, hypoadiponectinemia and arterial stiffness are strongly associated with cardiovascular diseases. We investigated the relationships among uric acid, adiponectin and arterial stiffness in postmenopausal women.

Study design

9555 subjects who had the routine health check-ups, 841 postmenopausal women aged 50 years or older who had not had a menstrual period for more than 12 consecutive months were included in this study.

Main outcome measures

BMI, WC, and serum concentrations of uric acid, adiponectin, glucose, lipids (total cholesterol, triglycerides, LDL cholesterol, and HDL cholesterol) were measured. Insulin resistance was estimated by the insulin resistance index of homeostasis model assessment (HOMA-IR). Pulse wave velocity (PWV) was evaluated to assess arterial stiffness.

Results

The subjects were stratified into three groups according to uric acid values. PWV values gradually increased and adiponectin level decreased with uric acid tertiles. Serum uric acid levels in postmenopausal women correlated significantly with age, BMI, WC, TG, HDL-C, insulin, HOMA-IR, adiponectin and PWV. Multiple regression analysis showed that WC (β = 0.141, P < 0.01), HOMA (β = 0.137, P < 0.01), adiponectin (β = −0.104, P < 0.01), and PWV (β = 0.129, P < 0.01) were independently correlated with uric acid levels. In multiple logistic regression analysis after adjusting for risk factors, uric acid was a significant contributor to increased PWV.

Conclusions

These findings indicate that serum uric acid is independently associated with adiponectin and arterial stiffness in postmenopausal women.     

Uric acid: a surrogate of insulin resistance in older women

OBJECTIVES: The relationship between serum uric acid (UA) and cardiovascular disease has been debated extensively and no conclusion has been reached yet. The main purpose of this study was to explore the sex-different relationship among insulin resistance, metabolic syndrome (MS) and hyperuricemia. METHODS: A community-based prospective study was conducted among people aged over 40 years in I-Lan County, Taiwan. A complete history taking, physical examination and laboratory tests were performed for each subject by the well-trained research staff. Insulin resistance was determined by the homeostasis model assessment (HOMA-IR). Serial comparisons were performed to evaluate the associations between MS, insulin resistance and hyperuricemia in both sexes. RESULTS: A total of 852 subjects (mean age=64.6+/-11.3 years, 56.7% female) were enrolled. The prevalence of obesity, hyperuricemia, chronic kidney disease (CKD), insulin resistance and MS was 42.2, 31.2, 30.9, 36.0 and 47.5%, respectively. Subjects with MS were significantly older (63.4+/-10.0 years versus 60.4+/-12.4 years, P=0.019), higher in body mass index (BMI) (26.3+/-3.5 kg/m(2) versus 23.6+/-3.0 kg/m(2), P<0.001), serum UA (6.1+/-2.1mg/dl versus 5.5+/-1.7 mg/dl, P=0.003), HOMA-IR (2.7+/-3.4 versus 1.0+/-0.8, P<0.001) and lower in glomerular filtration rate (GFR) (66.3+/-17.7 ml/min/1.73 m(2) versus 72.0+/-15.2 ml/min/1.73 m(2), P=0.001). Male gender, CKD, BMI>23 kg/m(2) and insulin resistance were all independent risk factor for hyperuricemia with the covariate of age. When age and BMI were controlled, females had significantly higher prevalence of CKD and insulin resistance, but less hyperuricemia than males (P all<0.05). Adjusted for age, BMI and GFR, hyperuricemia and MS were both independent risk factors for insulin resistance in females (P=0.006, <0.001, respectively). In males, MS remained significantly associated with insulin resistance (P=0.002) but not hyperuricemia (P=0.813). When age, BMI and GFR were controlled, serum UA was positively related to HOMA-IR in females (gamma=0.117, P=0.012), but not in males (P=0.93). CONCLUSION: A positive association was identified between serum UA and insulin resistance in older women but not in men. Studies related to insulin resistance may be needed when hyperuricemia was identified in older women.     

Association between C-reactive protein and pulmonary function in postmenopausal women

Objectives

The objective of this study is to investigate the association of CRP and impaired pulmonary function in postmenopausal women.

Methods

The study was carried out in Gangnam Severance Hospital in Korea between March 2006 and October 2008. A total of 5978 healthy women subjects (age range, 20–75 years) were recruited from Seoul. We performed a cross-sectional study to evaluate the association of CRP with impaired pulmonary function, especially the restrictive pattern in 1555 nonsmoking postmenopausal women. We evaluated CRP as a categorical variable and constructed three groups (a very low risk group, CRP < 0.5 mg/dl; a low risk group, 0.5–1.0 mg/dl; a medium and high risk group, 1.0–10.0 mg/dl). The odds ratios (ORs) for a low FVC were calculated across all three groups.

Results

CRP levels are negatively associated with forced expiratory volume (FEV₁)/forced vital capacity (FVC) and FVC after adjustment for confounding variables. The adjusted ORs (95% CIs) for a low FVC according to three groups were 1.00 (reference), 2.08 (1.03–4.20), and 2.55 (1.31–4.98) in postmenopausal women after adjusting for confounding variables.

Conclusions

In summary, increased C-reactive protein (CRP) levels are strongly and independently associated with impaired pulmonary function and more frequent a low FVC in postmenopausal women.     

Hormone replacement therapy, C-reactive protein, and fibrinogen in healthy postmenopausal women

Objective: To investigate short-term and long-term effects of combined hormone replacement therapy (HRT) on C-reactive protein (CRP) and fibrinogen plasma concentrations in healthy postmenopausal women. Methods: In this cross-sectional study 241 healthy postmenopausal women were enrolled. A total of 81 women were receiving the following treatments for 3 months; transdermal 17β-estradiol (17β-E₂)+medroxyprogesterone acetate (MPA) (n=21), oral 17β-E₂+norethisterone acetate (NETA) (n=27), and conjugated equine estrogens (CEE)+MPA (n=33). The same combined therapies were implemented in another 58 women for 12 months; transdermal 17β-E₂+MPA (n=10), oral 17β-E₂+NETA (n=16), and CEE+MPA (n=32). Control group included 102 healthy postmenopausal women not receiving HRT. The effect of the type and the duration of HRT regimens on plasma levels of CRP, fibrinogen and lipids were investigated. Results: Median CRP concentrations were significantly higher in women receiving oral 17β-E₂+NETA (P=0.037) and CEE+MPA (P=0.0001) for 3 months than in women taking the same types of HRT for 12 months and of those were not on HRT. Median CRP levels were similar in women taking transdermal 17β-E₂+MPA for 3 and 12 months, compared with controls. Fibrinogen levels were not different between nonusers and any group of HRT users. Conclusions: These elevated levels of CRP, which appears very recently as a crucial marker for cardiovascular disease, may be responsible for the early increased cardiovascular risk after starting oral combined HRT. But this increased risk in the early period seems to decrease with long-term use. Transdermal 17β-E₂+MPA had insignificant effect on CRP both in short-term or in long-term use.

目的测定子痫前期（preeclampsia,PE）孕妇孕中期血清脂联素及胰岛素抵抗的变化并探讨其意义。方法随机选择2009年7月至2010年7月在青岛大学医学院第二附属医院门诊检查的孕妇300名,进行前瞻性研究分析,根据妊娠结局,发展为子痫前期共31人纳入研究组（PE,n=31）,同时选取30名正常孕妇作为对照组。于24～28孕周时,采用放射免疫吸附法测定血清脂联素（adiponectin,APN）、胰岛素（Fastig insulin,Fins）,并测定空腹血糖（fasting blood sugar,FBG）及其他临床指标,稳定模型的胰岛素抵抗指数（homeostatic model assessment-insulin resistance,HOMA-IR）用（Fins×FBG）/22.5来表示。并进行相关分析。结果①子痫前期组孕妇平均动脉压（mean arterial blood pressure,MABP）与对照组比较明显升高,有统计学意义（P〈0.01）。②研究组与对照组比较,血清脂联素水平明显降低,有统计学差异（P〈0.01）。血清胰岛素及HOMA-IR明显升高,有统计学差异（P均〈0.01）。FBG两组比较无统计学差异（P〉0.05）。③研究组孕妇血清脂联素与胰岛素、HOMA-IR及MABP呈负相关（r=-0.87,r=-0.44,r=-0.51,P均〈0.01）,与BMI无相关关系（r=-0.26,P〉0.05）。研究组孕妇HOMA-IR与胰岛素、MABP呈正相关（r=0.42,r=0.77,P均〈0.01）,与BMI无相关关系（r=-0.04,P〉0.05）。结论孕中期低脂联素水平及高胰岛素抵抗与子痫前期的发生有关。     

Serum androgen levels and insulin resistance in postmenopausal women: association with hormone therapy, tibolone and raloxifene

OBJECTIVE: To assess endogenous androgen and insulin resistance status in postmenopausal women receiving continuous combined hormone therapy (HT), tibolone, raloxifene or no therapy. METHODS: A total of 427 postmenopausal women aged 42-71 years were studied in a cross-sectional design. Among them 84 were taking HT (46 women conjugated equine estrogens 0.625 mg; medroxyprogesterone acetate, 5 mg, CEE/MPA; and 38 women 17beta-estradiol 2 mg; norethisterone acetate 1 mg, E2/NETA); 83 were taking tibolone 2.5 mg; 50 were taking raloxifene HCl 60 mg; and 210 women were not receiving any therapy. Main outcome measures were FSH, LH, estradiol, total testosterone, SHBG, free androgen index (FAI), Delta4-Androstendione (Delta4-A), Dehydroepiandrosterone sulphate (DHEAS) and HOMA insulin resistance index (HOMA-IR). RESULTS: In women not on hormone therapy smoking and older age was associated with lower DHEAS levels. FAI values increased linearly with increasing BMI. Age and BMI were positive determinants of HOMA-IR, while no association was identified between endogenous sex steroids and insulin resistance. CEE/MPA therapy was associated with higher SHBG, lower FAI and lower HOMA-IR values compared to women not on therapy (age and BMI-adjusted SHBG: CEE/MPA 148.8 nmol/l, controls 58.7 nmol/l, p < 0.01; age-adjusted FAI: CEE/MPA 0.8, controls 3.2, p < 0.05; age-adjusted HOMA-IR: CEE/MPA 1.3, controls 2.6, p < 0.05). On the contrary, E2/NETA treatment had no effect on these parameters. Women on tibolone had lower SHBG, higher FAI and similar HOMA-IR values compared to controls (age and BMI-adjusted SHBG: 24.1 nmol/l, p < 0.01; FAI: 6.0, p < 0.05; HOMA-IR: 2.3, p = NS). Raloxifene users did not exhibit any difference with respect to sex steroids and HOMA-IR levels. CONCLUSIONS: CEE/MPA users had lower free testosterone and improved insulin sensitivity. Tibolone on the other hand associated with higher free testosterone, while raloxifene did not relate to any of these parameters.

Predictive ability of serum high-molecular-weight adiponectin in combination with serum insulin and serum C-reactive protein for the presence of metabolic syndrome

Background and aims: Metabolic syndrome (MetS) is an insulin-resistance syndrome deeply associated with obesity. The association between MetS and several clinical factors, including serum levels of adiponectin, C-reactive protein and insulin, was examined.

Subjects and methods: The study was performed in 219 men aged 43.2 ± 6.6 years, who were employees of a company. The study measured the serum high sensitivity C-reactive protein (CRP) as an inflammatory marker, serum insulin as a marker of insulin resistance and serum high-molecular-weight adiponectin (HMW-adipo), in addition to the serum levels of liver enzymes and uric acid. MetS was diagnosed according to the National Cholesterol Education Programme ATPIII criteria.

Results: Log-transformed serum ALT, HMW-adipo, insulin and uric acid were found to be significantly related to the presence/absence of Mets by logistic regression analysis, with odds ratios (95% confidence intervals) of 25.9 (3.3–204.4), 0.10 (0.02–0.56), 7.5 (1.6–34.1) and 1.5 (1.04–2.1), respectively.

Conclusion: Serum high HMW-adipo level was significantly negatively related to the presence of MetS, independently of the serum levels of insulin, liver enzymes and uric acid. Among the markers examined, serum HMW-adipo and ALT were considered as markers for MetS.

血尿酸与急性脑梗死相关危险因素的临床研究

目的：探讨急性脑梗死（acutecerebralinfarction,ACI）时血尿酸serumuricacid,SUA）水平及其与脑梗死相关危险因素的关系。方法：选取2012年1月至6月在唐山市协和医院神经内科住院的AcI病例共50N,检测患者SUA水平,并测定总胆固醇（totalcholesterol,TC）、三酰甘油（triglycerides,TG）、低密度脂蛋白胆固醇（10w—densitylipoproteincholesterol,LDL．C）、高密度脂蛋白胆固醇（high．densitylipoproteincholesterol,HDL—C）、高敏C反应蛋白（high．sensitivityC．reactiveprotein,HSC）及纤维蛋白原（fibrinogen,FIB）等。结果：50例ACI患者SUA总体水平为（310．18±100．56）μmol／L,10例为高尿酸血症患者。SUA≥360μmol／L时AcI伴高尿酸血症患者血HSC升高,与ACI不伴高尿酸血症患者HSC水平比较,差异有统计学意义fp=0．002）,而两者间TG（P=0．907）、TC（P=0．194）、HDL．C（P=0．411）、LDL—C（P=0．396）、FiB（P=0．159）等水平比较,差异无统计学意义。男性AcI患者SUA水平[（348．41±98．78）μmol／L]明显高于女性患者[（280．14±92．93）μmol／L;P=0．0161。50例ACI患者合并高血压者47例,合并2型糖尿病者19例,合并冠心病者36例,与未合并上述疾病患者SUA水平比较差异无统计学意义（均P〉O．05）。结论：高尿酸血症在ACI患者中与普通人群中的发生率相当。男性ACI患者高尿酸血症的风险高于女性。高血压、2型糖尿病、冠心病等ACI危险因素对患者SUA水平影响不显著。SUA可能作为一种炎症因子参与并加重ACI的炎症过程,并可能参与多个致病环节,通过多个途径影响疾病的发生、进展及其预后。     

多囊卵巢综合征患者脂联素和C一反应蛋白与颈动脉内膜中层厚度的关系

目的观察多囊卵巢综合征(PCOS)患者血清脂联素(APN)水平和C一反应蛋白(CRP)浓度与颈动脉内膜中层厚度(IMT)的关系,探讨PCOS患者是否存在早期动脉粥样硬化。方法选择我院PCOS患者51例作为研究对象,分为肥胖组与非肥胖组,同期选择非PCOS患者50例作为对照,测定血清APN水平和CRP浓度及内分泌代谢指标,同时采用彩色多普勒显像仪测量颈总动脉IMT。结果 PCOS肥胖组及非肥胖组血清APN水平低于对照组(P<0.05),CRP浓度、颈动脉IMT均明显高于对照组(P<0.05)。PCOS肥胖组血清APN水平低于非肥胖组(P<0.05);PCOS肥胖组血清CRP浓度、IMT高于非肥胖组,差异有统计学意义(P<0.05)。相关分析显示PCOS组APN与CRP,IMT、HOMA-IR均有显著的负相关(P<0.05或P<0.01)。CRP与IMT、HOMA-IR具有显著的正相关(P<0.05或P<0.01)。结论 PCOS患者尤其伴有肥胖者血清脂联素水平降低,CRP浓度升高,胰岛素抵抗增加,IMT增加,可能存在早期动脉粥样硬化。炎症反应可能参与了PCOS患者尤其伴有肥胖者早期动脉粥样硬化的发生发展。     

原发性高血压患者血清可溶性E选择素水平与胰岛素抵抗的关系

目的:探讨高血压病患者血清可溶性E-选择素(sE-selectin)浓度与胰岛素抵抗、尿酸及血脂的关系。方法:测定186例高血压病患者(男75例,女111例)的空腹血清sE-selectin、血糖、胰岛素、尿酸、总胆固醇、甘油三酯、高密度脂蛋白胆固醇、低密度脂蛋白胆固醇的浓度,稳态模式评估法计算胰岛素抵抗指数(HOMA-IR)。分析血清sE-selectin浓度与其它各项参数的相关性。结果:以HOMA-IR50%位点,作为判断胰岛素抵抗的切割点,把高血压病患者分为胰岛素抵抗组(IR)与胰岛素敏感组(IS)。男性组血清sE-selectin浓度(50.1±17.8)μg/L显著高于女性组(40.6±16.6)μg/L;男性IR组(51.6±16.8)μg/L与IS组(48.5±18.8)μg/L无显著差异;女性IR组(45.1±18.0)μg/L显著高于IS组(36.0±13.7)μg/L。逐步回归分析显示,男性组HOMA-IR非血清sE-selectin浓度的独立预测因子,但女性组HOMA-IR是血清sE-selectin浓度的独立预测因子;尿酸和血脂均非血清sE-selectin浓度的独立预测因子。结论:女性原发性高血压患者血清sE-selectin浓度与胰岛素抵抗直接相关,男性则无直接相关;尿酸及血脂与血清sE-selectin浓度均无直接相关。     

Association between C-reactive protein and depressive symptoms in women with rheumatoid arthritis

Converging lines of evidence support an association between systemic inflammation and depressive symptoms. Neuroimmune pathways may account for the high prevalence of depression in individuals with inflammatory conditions such as rheumatoid arthritis (RA). However, this relationship is complicated by factors linked to both inflammatory disease activity and mood, such as pain and physical disability. The goal of this cross-sectional study was to examine the relationship between C-reactive protein (CRP) and depressive symptoms among 173 women with RA. Somatic symptoms of depression and circulating CRP were significantly associated in regression analyses adjusted for body mass index (β = .19, p < .05), but this relationship was attenuated when pain and disability were included as covariates (β = .09, p = .24). CRP was not significantly associated with negative mood symptoms of depression. Findings suggest that depression in the context of RA may result from the overlap of somatic depressive and RA symptoms rather than neuroimmune pathways.     

C反应蛋白表达在2型糖尿病大血管病变中意义

目的:探讨C反应蛋白(CRP)与2型糖尿病(T2DM)大血管病变发生的关系。方法:将T2DM患者60人随机分为合并大血管并发症组与无大血管并发症组,每组各30例,正常对照组30例。检测病人血清中血脂、糖化血红蛋白(HbA1c)和CRP水平。结果:2型DM患者的CRP水平明显高于正常对照组(P<0.05),其中有大血管并发症组显著高于无大血管并发症组(P<0.05),Logstic回归分析显示,CRP水平是T2DM患者大血管并发症发生的独立危险因素。结论:CRP与T2DM的发生相关,升高的CRP是促使T2DM并发大血管病变的独立危险因素。     

2型糖尿病患者C反应蛋白、脂联素和瘦素水平与胰岛素抵抗的相关性

目的探讨C反应蛋白(CRP)、脂联素(APN)、瘦素(Leptin)水平、胰岛素抵抗指数(HOMA-IR)与2型糖尿病(T2DM)病变易患因素的关系。方法用RIA法测定2型糖尿病患者血浆leptin和胰岛素(FINS),用ELSIA法测定血清ANP,用全自动生化分析仪常规测定血清CRP、空腹血糖(FPG),计算胰岛素抵抗指数(HOMA-IR,FPG×FINS/22.5),以正常健康体检者为对照组,进行对比分析。结果 CRP、leptin、HOMA-IR在2型糖尿病组显著高于对照组(P<0.01),ANP显著低于对照组(P<0.01);线性相关显示2型糖尿病HOMA-IR与CRP(r=0.36,P<0.05)、leptin(r=0.39,P<0.05)呈正相关,2型糖尿病HOMA-IR与APN(r=-0.32,P<0.05)呈负相关。结论低APN和高CRP、leptin血症可能是糖尿病的发病因子,它们的代谢紊乱与胰岛素抵抗有密切关系。
