Association between hemoglobin glycation index and subclinical myocardial injury in the general population free from cardiovascular disease

Background and aimsThe relationship between hemoglobin glycation index (HGI) and the diagnosis and prognosis of cardiovascular disease (CVD) has been verified by previous studies. However, it remains unknown whether HGI has a predictive effect on subclinical myocardial injury (SC–MI). The purpose of the present study was to explore the relationship between HGI and SC–MI in the general population free from CVD.Methods and resultsThe present study included 6009 participants free of CVD from the third National Health and Nutrition Examination Survey. Binary Logistic regression analysis was used to tested the association between HGI and SC–MI. As results, the HGI was significantly higher in participants with SC–MI compared with those without, and the HGI was positively correlated with SC–MI and other metabolic disorder parameters. Each 1-unit increase of HGI and glycated hemoglobin A1c (HbA1c) was independently associated with higher risk of SC–MI (P < 0.05), while fasting plasma glucose (FPG) was no longer a predictive indicator of SC–MI with the increase of confounding factors [OR (95% CI): 1.001 (0.999–1.003), P = 0.305]. And in the subgroup analysis, HGI, only in participants without diabetes, was independently associated with higher risk of SC–MI, while HbA1c and FPG had no independent predictive role in both diabetic and non-diabetic participants.ConclusionsHGI was a significant predictor of SC–MI in the general population free from CVD.     

Association of cognitive function with serum uric acid level among Chinese nonagenarians and centenarians

This cross-sectional study aimed to assess the association of risk of cognitive impairment with level of serum uric acid (SUA) among very old people, specifically in a cohort of 694 unrelated Chinese aged 90–108 years. Cognitive function was measured using the 30-item Mini-Mental State Examination (MMSE) and SUA level was determined by the uricase–peroxidase method. Cognitive impairment was defined as a score below 18 on the Folstein MMSE. Men had significantly higher cognitive function scores than did women: 17.6 ± 5.6 vs. 14.0 ± 5.2 (P < 0.05). In the total sample, the prevalence of cognitive impairment was 71.6%, with the rates being 50.9% and 81.6% for males and females, respectively (P < 0.000). Men had significantly higher SUA levels than women: 354.1 ± 85.7 vs. 303.8 ± 81.7 mmol/L (P = 0.000). Binary logistic regression analysis indicated an inverse correlation between the risk of cognitive impairment and SUA (OR = 0.996) in men. In conclusion, in male nonagenarians and centenarians, the higher level of SUA is related to the lower risk of cognitive impairment.     

Elevated serum uric acid is a predictor of contrast associated acute kidney injury in patient with ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention

BackgroundContrast associated-acute kidney injury (CA-AKI) has been associated with adverse outcomes after ST-segment elevation myocardial infarction (STEMI). However, early markers of CA-AKI are still needed to improve risk stratification. We investigated the association between elevated serum uric acid (eSUA) and CA-AKI in patients with STEMI treated with primary percutaneous coronary intervention (pPCI).Methods and resultsSerum creatinine (Scr) was measured at admission and 24, 48 and 72 h after pPCI. CA-AKI was defined as an increase of 25% (CA-AKI 25%) or 0.5 mg/dl (CA-AKI 0.5) of Scr level above the baseline after 48 h following contrast administration. Multivariable analyses to investigate CA-AKI predictors were performed by binary logistic regression and multivariable backward logistic regression model.In the 3023 patients considered, CA-AKI was more frequent among patients with eSUA as compared with patients with normal SUA levels, considering both CA-AKI definitions (CA-AKI25%: 20.8% vs 16.2%, p < 0.012; CA-AKI 0.5: 10.1% vs 5.8%, p < 0.001). The association between eSUA and CA-AKI was confirmed at multivariable analyses (CA-AKI 25%: odd ratio 1.32, 95% CI 1.03–1.69, p = 0.027; CA-AKI 0.5: odd ratio 1.76, 95% CI 1.11–2.79, p = 0.016).ConclusionElevated serum uric acid is associated with CA-AKI after reperfusion in patients with STEMI treated with pPCI.     

青岛地区不同糖代谢状态人群血尿酸水平的变化

从青岛地区糖尿病(DM)和高尿酸血症流行病学调查数据库中,排除既往已诊断糖尿病者,对资料完整者3125例,按照不同糖代谢状态、BMI、高血压(HT)和TG水平分组,比较血尿酸(SUA)水平的变化。调整年龄、BMI和TG后,新诊断DM的SUA水平明显低于正常糖耐量组(NGT)和糖调节受损组(IGR)(P均<0.05),其中在男性,NGT组的SUA水平最高(390±3μmol/L),而在女性IGR组SUA水平(328±5μmol/L)明显高于NGT和新诊断DM组(P均<0.05);BMI>27.8kg/m2亚组的SUA水平为最高(P<0.01);高血压组和高TG组的SUA水平均分别高于正常血压和正常TG组(P分别为<0.05和<0.01)。随着NGT、IGT到新诊断DM糖代谢异常的加重SUA水平下降,可能是机体抗氧化反应减弱的一种表现,而在高血压组的SUA升高可作为血管并发症的预测指标。     

氯沙坦（科素亚）促尿酸排泄作用的临床研究

目的 尿酸是高血压病的危险因素之一,其主要表现为血尿酸（SUA）升高。由于高血压病人肾功能减退或肾血流量下降,故高血压患中高尿酸血症较正常血压多。高血压患中,伴有高尿酸血症心血管事件增多。在高血压病的治疗中,特异性阻断1型血管紧张素Ⅱ（AT1)受体的血管紧张素Ⅱ（ATⅡ）拮抗剂－氯沙坦（科素亚）。业已显示它是一个有效的降血压药物,且有促尿酸排泄作用。本收集了60例本院住院高血压病（1－2级）病人。随机抽取30例作治疗组,单独应用氯沙坦（科素亚）治疗。另30例作对照组。观察表明,氯沙坦（科素亚）可显促尿酸排泄,降低血尿酸水平。     

血清尿酸与高尿酸血症相关疾病

尿酸是人体嘌呤碱基分解代谢终产物,经肾脏排泄。体内尿酸生成超过肾脏排泄时血清尿酸会显著升高,造成高尿酸血症。高尿酸血症与痛风、心血管疾病、肿瘤裂解综合征及肾脏疾病的引发或加剧密切相关。本文对血清尿酸的临床意义进行综述。

Abstract：

Objective To evaluate the relationship between hyperuricemia and nonalcoholic fatty liver disease(NAFLD) by observing the prevalence of NAFLD among healthy individuals with different levels of serum uric acid.Methods The data of 5 230 persons from medical centers for health examination were analyzed,such as height,weight,blood pressure,blood lipids,blood sugar, hepatitis-related markers, and abdominal color Doppler ultrasound examination were conducted in the fasting state.The diagnosis of NAFLD was made according to the diagnostic criteria adopted by China Institute of Liver Disease and Alcoholic Liver Disease Group.Results The incidences of overweight or obesity, hypertension,hyperlipidemia, and metabolic syndrome were raised with serum uric acid greater than 333 μmol/L in male and＞233 μmol/L in female subjects(P＜0.05 or P＜0.01). Excluding the metabolic syndrome in male subjects, the incidence of NAFLD was increased with serum uric acid,＞333 μmol/L in males or ＞233 μmol/L in females(P＜0.05 or P＜0.01). In further studies with subjects without any metabolic syndrome, the detection rate of NAFLD was higher in males than in females at the same serum uric acid level(P＜0.01). Logistic regression analysis showed that sex, body mass index, blood glucose, and triglyceride, low-density lipoprotein cholesterol, uric acid grading were risk factors of NAFLD(OR 1.344, 2.500, 1.292, 1.279, 1.244, 1.256 respectively).Conclusion A high serum uric acid level is associated with an increased risk of NAFLD.

Elevated serum uric acid is associated with a greater inflammatory response and with short- and long-term mortality in patients with ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention

Background and aimsDespite elevated serum uric acid (eSUA) has been identified as independent risk factor for cardiovascular diseases, its prognostic value in the setting of ST-segment elevation myocardial infarction (STEMI) is still controversial. Although the mechanisms of this possible relationship are unsettled it has been suggested that eSUA could trigger the inflammatory response. This study sought to investigate the association between eSUA with short- and long-term mortality and with inflammatory response in patients with STEMI treated with primary percutaneous coronary intervention (pPCI).Methods and resultsBlood samples were collected on admission and at 24 and 48 h after pPCI: the inflammatory biomarkers C-reactive protein (CRP), neutrophil count and neutrophil to lymphocytes ratio (NLR) were considered. Baseline eSUA was defined as ≥6.8 mg/dl. Cumulative 30-days and 1-year mortalities were estimated using the Kaplan-Meyer analysis. Multivariable analyses were performed by Cox proportional hazard models.In the 2369 patients with STEMI considered, 30-day mortality was 5.8% among patients with eSUA and 2% among patient with normal SUA level (p < 0.001); 1-year mortality was 8.5% vs 4%, respectively (p < 0.001). At multivariable analyses eSUA was an independent predictor of 30-day mortality (HR 1.196, 95%CI 1.006–1.321, p = 0.042) and 1-year mortality (HR 1.178, 95%CI 1.052–1.320, p = 0.005). eSUA patients presented higher values in on admission CRP (p < 0.001) and in neutrophil count and NLR at 24 h (respectively, p = 0.020 and p < 0.001) and at 48 h (p = 0.018 and p < 0.001) compared to patients with normal SUA levels.ConclusionsElevated serum uric acid is associated with higher short- and long-term mortality and with a greater inflammatory response after reperfusion in patients with STEMI treated with primary PCI.     

血尿酸与冠心病的相关性分析

目的分析研究冠心病和血尿酸的形成、扩散与患者治疗、恢复之间的关系。方法抽取近年来在我院给予血尿酸检测的冠心病病人180例（实验组）,并且再次抽取在这期间在我院进行常规体检的健康人群180例（对照组）当做对比分析观察。结果实验组病人的血尿酸含量：（421．23±43．52）μmol／L;对照组的血尿酸含量：（362．45±40．57）μmol／L,两组间差异具有统计学意义（P〈0．05）;然而心绞痛和陈旧性心肌梗死病人的血尿酸水平明显优于急性心肌梗死以及对照组病人,其差异具有统计学意义（P〈0．05）;急性心肌梗死病人的血尿酸水平（平均）和对照组差异不具有统计学意义（P〈0．05）。结论冠心病的形成、扩散是造成患者血尿酸的浓度升高的重要因素,对于冠心病病人应该采取定期对血尿酸进行检测,这样对及时预防这种疾病的发生具有非常大的帮助,对病人的生活质量起到至关重要的作用．具有临床推广价值应用。
