目的分析经肝活检确诊的代谢相关性脂肪性肝病(metabolic associated fatty liver disease, MAFLD)患者发生明显肝纤维化的危险因素。方法回顾性分析193例经肝活检确诊的MAFLD患者发生明显肝纤维化的危险因素。结果与MAFLD伴无/轻微肝纤维化(F0~1)患者比较,MAFLD伴明显肝纤维化(F2~4)患者中女性比例更高、年龄更大、肥胖更多见、伴高血压病者更多(P均<0.05);与MAFLD伴无/轻微肝纤维化(F0~1)患者比较,MAFLD伴明显肝纤维化(F2~4)患者外周血中血红蛋白水平及血小板计数更低(P<0.05),血清中白蛋白及尿酸水平更低(P<0.05),而TBA及空腹血糖水平更高(P<0.05)。单因素回归分析发现,女性(OR=2.277, 95%CI:1.181~4.390)、高血压病(OR=3.305, 95%CI:1.606~6.801)、BMI(OR=1.083, 95%CI:1.006~1.167)、年龄(OR=1.030,95%CI:1.006~1.055)、血红蛋白(OR=0.978,95%CI:0.958~0.997)及血小板计数(OR=0.998,95%CI:0.989~1.000)是MAFLD患者发生明显肝纤维化的危险因素,而多因素回归分析发现,高血压病(OR=2.662,95%CI:1.092~6.489)、BMI(OR=1.163,95%CI:1.062~1.275)及血小板计数(OR=0.993,95%CI:0.987~0.999)是MAFLD患者发生明显肝纤维化的独立危险因素。结论高血压、BMI及血小板计数是肝活检确诊的MAFLD患者发生明显肝纤维化的独立危险因素。     

Characteristics of and risk factors for colorectal neoplasms in young adults in a screening population

AIM: To investigate prevalence and risk factors for colorectal neoplasms in adults aged 50 years, for whom screening is not recommended.METHODS: This cross-sectional study compared prevalence and characteristics of colorectal and advanced adenomas in patients aged 50 years who underwent colonoscopy screening with subjects aged ≥ 50 years. To evaluate risk factors for colorectal and advanced adenoma in young adults, we used multivariable logistic regression models. Colorectal neoplasm characteristics were evaluated and compared with those in older patients.RESULTS: Among 2819 patients included, prevalences of colorectal adenoma and advanced adenoma were 19.7% and 1.5%, respectively. As patient age increased, so did the prevalence of colorectal neoplasm. However, prevalence of advanced adenoma did not differ between age-groups 45-49 years and ≥ 50 years(OR = 0.43, 95%CI: 0.17-1.07, P = 0.070). In younger age-group( 50 years), colorectal adenoma was significantly associated with older age, waist circumference(OR = 1.72, 95%CI: 1.15-2.55, P = 0.008), and current smoking(OR = 1.60, 95%CI: 1.07-2.41, P = 0.023). Alcohol consumption was an independent risk factor for colorectal advanced adenoma(OR = 3.69, 95%CI: 1.08-12.54, P = 0.037). Multiple neoplasms and large neoplasms(≥ 1 cm) were more prevalent in subjects ≥ 50 years.CONCLUSION: Current screening strategies for colorectal cancer may need to be amended to account for patient age, especially in young subjects with abdominal obesity, current smoking and alcohol consumption.     

Lean-non-alcoholic fatty liver disease increases risk for metabolic disorders in a normal weight Chinese population

AIM: To study the prevalence and clinical biochemical, blood cell and metabolic features of lean-non-alcoholic fatty liver disease (lean-NAFLD) and its association with other diseases.METHODS: Demographic, biochemical and blood examinations were conducted in all the subjects in this study. We classified the subjects into four groups according to their weight and NAFLD status: lean-control, lean-NAFLD [body mass index (BMI) < 24 kg/m²], overweight-obese control and overweight-obese NAFLD. One-way analysis of variance (ANOVA) was used to compare the means of continuous variables (age, BMI, blood pressure, glucose, lipid, insulin, liver enzymes and blood cell counts) and the χ² test was used to compare the differences in frequency of categorical variables (sex, education, physical activity, smoking, alcohol consumption and prevalence of hypertension, hyperlipidemia, diabetes, metabolic syndrome central obesity and obesity). Both univariate and multivariate logistic regression models were adopted to calculate odds ratios (ORs) and predict hyperlipidemia, hypertension, diabetes and metabolic syndrome when we respectively set all controls, lean-control and overweight-obese-control as references. In multivariate logistic regression models, we adjusted potential confounding factors, including age, sex, smoking, alcohol consumption and physical activity.RESULTS: The prevalence of NAFLD was very high in China. NAFLD patients were older, had a higher BMI, waist circumference, blood pressure, fasting blood glucose, insulin, blood lipid, liver enzymes and uric acid than the controls. Although lean-NAFLD patients had lower BMI and waist circumstance, they had significantly higher visceral adiposity index than overweight-obese controls. Lean-NAFLD patients had comparable triglyceride, cholesterin and low-density lipoprotein cholesterin to overweight-obese NAFLD patients. In blood cell examination, both lean and overweight-obese NAFLD was companied by higher white blood cell count, red blood cell count, hemoglobin and hematocrit value. All NAFLD patients were at risk of hyperlipidemia, hypertension, diabetes and metabolic syndrome (MetS). Lean-NAFLD was more strongly associated with diabetes (OR = 2.47, 95%CI: 1.14-5.35), hypertension (OR = 1.72, 95%CI: 1.00-2.96) and MetS (OR = 3.19, 95%CI: 1.17-4.05) than overweight-obese-NAFLD (only OR for MetS was meaningful: OR = 1.89, 95%CI: 1.29-2.77). NAFLD patients were more likely to have central obesity (OR = 1.97, 95%CI: 1.38-2.80), especially in lean groups (OR = 2.17, 95%CI: 1.17-4.05).CONCLUSION: Lean-NAFLD has unique results in demographic, biochemical and blood examinations, and adds significant risk for diabetes, hypertension and MetS in lean individuals.     

Sex-influenced association of non-alcoholic fatty liver disease with colorectal adenomatous and hyperplastic polyps

AIM To investigate the relationship between non-alcoholic fatty liver disease(NAFLD) and colorectal adenomatous and hyperplastic polyps.METHODS A retrospective cross-sectional study was conducted on 3686 individuals undergoing health checkups(2430 males and 1256 females). All subjects underwent laboratory testing,abdominal ultrasonography,colonoscopy,and an interview to ascertain the baseline characteristics and general state of health. Multinomial logistic regression analysis was performed to examine the association between NAFLD and the prevalence of colorectal adenomatous and hyperplastic polyps.Furthermore,the relationship was analyzed in different sex groups. Subgroup analysis was performed based on number,size,and location of colorectal polyps.RESULTS The prevalence of colorectal polyps was 38.8% in males(16.2% for adenomatous polyps and 9.8% for hyperplastic polyps) and 19.3% in females(8.4% for adenomatous polyps and 3.9% for hyperplastic polyps). When adjusting for confounding variables,NAFLD was significantly associated with the prevalence of adenomatous polyps(OR = 1.28,95%CI: 1.05-1.51,P 0.05) and hyperplastic polyps(OR = 1.35,95%CI: 1.01-1.82,P 0.05). However,upon analyzing adenomatous and hyperplastic polyps in different sex groups,the significant association remained in males(OR = 1.53,95%CI: 1.18-2.00,P 0.05; OR = 1.42,95%CI: 1.04-1.95,P 0.05) but not in females(OR = 0.44,95%CI: 0.18-1.04,P 0.05; OR = 1.18,95%CI: 0.50-2.78,P 0.05). CONCLUSION NAFLD is specifically associated with an increased risk of colorectal adenomatous and hyperplastic polyps in men. However,NAFLD may not be a significant factor in the prevalence of colorectal polyps in women.

目的探讨中老年人群中非酒精性脂肪性肝病(NAFLD)与代谢综合征相关指标变化的关系。方法收集2010—2011年暨南大学附属第一医院40岁以上体检人群腹部B超检查的数据,用多因素Logistic回归分析体重指数(BMI)、空腹血糖(FBG)、三酰甘油(TG)、总胆固醇(TC)、高密度脂蛋白胆固醇(HDL-C)及低密度脂蛋白胆固醇(LDL-C)、丙氨酸转氨酶(ALT)、血尿酸(UA)的变化值与NAFLD变化的关系。结果 2年内男性组和女性组NAFLD检出率都在增加,男性新增NAFLD总检出率为13.7%,明显高于女性新增NAFLD检出率7.5%(P<0.05);男性和女性的NAFLD消减率都是5.5%,且峰值都在60岁年龄组;BMI变化值与新增NAFLD密切正相关,BMI变化值的OR=1.474(95%CI 1.184～1.811),而TG和FBG的变化值与新增NAFLD无相关性;TG和BMI的变化值与NAFLD的消减呈负相关,TG变化值的OR=0.653(95%CI 0.508～0.838),BMI变化值的OR=0.628(95%CI 0.460～0.857),而FBG变化值未发现与NAFLD消减有相关性。结论 BMI变化值与NAFLD发生有密切相关性,TG和BMI的变化值与NAFLD的消减呈负相关,是影响NAFLD变化的重要因素之一。     

不同性别高血红蛋白水平对非酒精性脂肪性肝病发生风险的影响

目的探讨不同性别Hb浓度和非酒精性脂肪性肝病（NAFLD）发生风险之间的关系。方法以2012年1月至2012年12月上海市仁济医院健康保健中心年龄≥18岁的体检人群为研究对象,依据男女Hb的不同进行分组,评估各组NAFLD的患病率。结果入组的61 646人中,平均年龄（44±14）岁,男性34 961人,女性26 685人。超声诊断为NAFLD者20 401人,占33.09%。不论在男性组还是女性组,NAFLD患病率随着Hb水平的升高而升高（P〈0.001）,男性NAFLD的患病率高于女性（44.7%比17.9%,χ2=4 900,P〈0.001）,在Logistic回归分析中,NAFLD患病率和Hb水平呈现正相关的关系,在男性组,作多变量分析时,第1组作为参照,第2组、第3组、第4组的OR值分别为1.31（95%CI：1.18-1.45）、1.38（95%CI：1.24-1.53）、1.29（95%CI：1.05-1.58）,均P〈0.05。在女性组,多变量分析时,OR值分别为1.08（95%CI：0.95-1.22）、1.26（95%CI：1.09-1.45）、1.59（95%CI：1.06-2.38）,除第2组外,另两组均P〈0.05。男性患NAFLD的风险较女性高（OR为3.7,95%CI：3.57-3.85,P〈0.001）。结论 Hb水平和NAFLD呈正相关关系,高Hb水平是独立于肥胖和代谢综合征的NAFLD的又一风险因素。男性NAFLD发生风险是女性的3.7倍。     

Prevalence and risk factors of nonalcoholic fatty liver disease in an adult population of taiwan: metabolic significance of nonalcoholic fatty liver disease in nonobese adults

BACKGROUND: The prevalence of nonalcoholic fatty liver disease (NAFLD) is rarely reported in Taiwan. GOALS: To determine the prevalence and risk factors of NAFLD in an adult population of Taiwan. STUDY: The cross-sectional community study examined 3245 adults in a rural village of Taiwan. The diagnostic criteria for NAFLD included no excessive alcohol intake, no chronic viral hepatitis, no known etiologies of liver disease, and ultrasonography consistent with fatty liver. RESULTS: The prevalence of NAFLD was 11.5% (372/3245). The risk factors for NAFLD in the general population were male sex [odds ratio (OR), 1.44; 95% confidence interval (CI), 1.09-1.90], elevated alanine aminotransferase (ALT) (OR, 5.66; 95% CI, 3.99-8.01), obesity (OR, 7.21; 95% CI, 5.29-9.84), fasting plasma glucose > or =126 mg/dL (OR, 2.08; 95% CI, 1.41-3.05), total cholesterol > or =240 mg/dL (OR, 1.50; 95% CI, 1.06-2.13), triglyceride > or =150 mg/dL (OR, 1.76; 95% CI, 1.32-2.35), and hyperuricemia (OR, 1.53; 95% CI, 1.16-2.01). Age > or =65 years was inversely related to NAFLD (OR, 0.53; 95% CI, 0.36-0.77). The only NAFLD risk factors among nonobese subjects were age between 40 and 64 years (OR, 2.35; 95% CI, 1.34-4.11, P=0.003), elevated ALT (OR, 15.45; 95% CI, 8.21-29.09, P<0.001), and triglyceride > or =150 mg/dL (OR, 2.48; 95% CI, 1.42-4.32, P=0.001). In subjects with NAFLD, the prevalence of elevated ALT in the presence of each metabolic risk factor, such as obesity, fasting plasma glucose > or =126 mg/dL, total cholesterol > or =240 mg/dL, triglyceride > or =150 mg/dL, and hyperuricemia, did not differ from that of subjects with normal ALT levels. CONCLUSIONS: NAFLD is closely associated with elevated ALT, obesity, diabetes mellitus, hypercholesterolemia, hypertriglyceridemia, and hyperuricemia. Among the metabolic disorders, only hypertriglyceridemia was related to NAFLD in nonobese subjects. Serum ALT level was not a good predictor of metabolic significance in subjects with NAFLD.     

Prevalence and etiology of elevated serum alanine aminotransferase level in an adult population in Taiwan

BACKGROUND: The prevalence and etiologies of elevated alanine aminotransferase (ALT) have geographic variations and they are rarely reported in Taiwan. Through a population-based screening study, the prevalence and etiologies of elevated ALT in an adult population of Taiwan were assessed. METHODS: A cross-sectional community study in a rural village of Taiwan was conducted in 3260 Chinese adults (age >or=18 years) undergoing ultrasonography (US), blood tests, and interviews with a structured questionnaire. The diagnostic criteria of non-alcoholic fatty liver disease (NAFLD) included alcohol intake <20 g/week for women or <30 g/week for men, negative hepatitis B virus (HBV) and hepatitis C virus (HCV) infections, no known etiologies of liver disease, and US consistent with fatty liver. RESULTS: The prevalence of elevated ALT was 11.4% (372/3260). The probable cause of this elevation was excess alcohol consumption in 0.8%, HBV in 28.5%, HCV in 13.2%, both HBV and HCV in 2.2%, NAFLD in 33.6%, and unexplained cause in 21.8%. The etiologic distribution of elevated ALT was similar in both genders, although elevation was more common in men compared to women (17.3%vs 6.1%, P < 0.05). The prevalence of elevated ALT in NAFLD was 18.1% (125/691), and the positive predictive value was 33.6% (125/372). The development of NAFLD was related to increasing age (age between 40 years and 64 years, odds ratio [OR] 1.59, 95% confidence interval [CI]: 1.25-2.01; age >or= 65 years, OR 1.46, 95%CI: 1.08-1.96), fasting plasma glucose (FPG) >or= 126 mg/dL (OR 1.54, 95%CI: 1.11-2.14), body mass index (BMI) >or= 25 kg/m(2) (OR 5.01, 95%CI: 4.13-6.26), triglyceridemia >or= 150 mg/dL (OR 1.96, 95%CI: 1.58-2.42), and hyperuricemia (OR 1.50, 95%CI: 1.22-1.84). Elevated ALT was related to male gender, BMI >or= 25 kg/m(2), and triglyceridemia >or= 150 mg/dL in subjects without known etiologies of liver disease (all P < 0.05). CONCLUSIONS: Non-alcoholic fatty liver disease appears to be the commonest cause of elevated ALT and presumed liver injury in Taiwan. The development of NAFLD is closely associated with many metabolic disorders. Metabolic disorders are also related to elevated ALT in subjects without known etiologies of liver disease.
