| 1 | 非酒精性脂肪性肝病和非酒精性脂肪性肝炎的无创性诊断显示文摘非酒精性脂肪性肝病(NAFLD)在美国和世界上许多其他地区都是最常见的慢性肝病,其患病率持续上升,目前美国约1/4的成人和10%的儿童患NAFLD。NAFLD包括多种疾病状态,从通常呈良性、非进展性临床过程的单纯性脂肪肝直至更为严重的、可进展为肝硬化和终末期肝病的非酒精性脂肪性肝炎(NASH)。目前,NASH的诊断依赖于创伤性肝活检,而肝活检存在取样和读片误差的缺陷。NASH的临床危险因素包括糖尿病和代谢综合征,但这些因素本身不足以预测NASH。常规肝酶水平预测可靠性低,新型血浆肝细胞死亡标记物单独或与临床危险因素联合今后可能成为无创性诊断工具。本文对无创性诊断工具在鉴别单纯性脂肪肝与NASH以及确定肝纤维化的存在及其范围中的作用作一概述。 | Leon A ADAMS Ariel E FELDSTEIN 张海燕 钱本余 马雄 | 2011 | 胃肠病学2011，16，3： | 2 |
| 10 | Burden of nonalcoholic fatty liver disease and advanced fibrosis in a Texas Hispanic community cohort显示文摘AIM: To investigate the potential burden of nonalcoholic steatohepatitis(NASH) and advanced fibrosis in a hispanic community.METHODS: Four hundred and forty two participants with available ultrasonography data from the Cameron County Hispanic Cohort were included in this study. Each participant completed a comprehensive questionnaire regarding basic demographic information, medical history, medication use, and social and family history including alcohol use. Values of the nonalcoholic fatty liver disease fibrosis score(NFS), FIB4 index, BARD score, and Aspartate aminotransferase to Platelet Ratio Index(APRI) were computed using the blood samples collected within 6 mo of liver ultrasonography from each participant. Hepatic steatosis was determined by ultrasonography. As part of univariable analysis, for continuous variables, comparisons among groups were performed with student-t test, one way analysis of variance, and Mann-Whitney test. Pearson χ2 and the Fisher exact test are used to assess differences in categorical variables. For multivariable analyses, logistic regression analyses were performed to identify characteristics associated with hepatic steatosis. All reported P values are based two-sided tests, and a P value of less than 0.05 was considered to indicate statistical significance.RESULTS: The mean age and body mass index(BMI) of the study participants were 49.1 years and 31.3 kg/m2, respectively. Among them, 65.6% were females, 52% had hepatic steatosis, 49.5% had metabolic syndrome, and 29% had elevated aminotransferases. Based on established cut-offs for diagnostic panels, between 17%-63% of the entire cohort was predicted to have NASH with indeterminate or advanced fibrosis. Participants with hepatic steatosis had significantly higher BMI(32.9 ± 5.6 kg/m2 vs 29.6 ± 6.1 kg/m2, P < 0.001) and higher prevalence rates of elevation of ALT(42.2% vs 14.6%, P < 0.001), elevation of aspartate aminotransferase(38.7% vs 18.9%, P < 0.001), and metabolic syndrome(64.8% vs 33%, P < 0.001) than those without hepatic steatosis. The NFS scores(P = 0.002) and the APRI scores(P = 0.002) were significantly higher in those with steatosis but the scores of the FIB4 index and BARD were similar between the two groups. After adjusting for age, gender and BMI, elevated transaminases, metabolic syndrome and its components, intermediate NFS and APRI scores were associated hepatic steatosis in multivariable analysis. CONCLUSION: The burden of NASH and advanced fibrosis in the Hispanic community in South Texas may be more substantial than predicted from referral clinic studies. | Jen-Jung Pan Susan P Fisher-Hoch Chaoru Chen Ariel E Feldstein Joseph B Mc Cormick Mohammad H Rahbar Laura Beretta Michael B Fallon | 2015 | World Journal of Hepatology2015，7，11： | 0 |
