The aim of this study was to define the upper limit of normal (ULN) for serum ALT levels, and to assess factors associated with serum ALT activity in apparently healthy blood donors. METHODS: A total of 1 939 blood donors were included.ALT measurements were performed for all cases using the same laboratory method. Healthy ranges for ALT levels werecomputed from the population at the lowest risk for liver disease. Univariate and multivariate analyses were performed to evaluate associations between clinical factors and ALT levels.RESULTS: Serum ALT activity was independently associated with body mass index (BMI) and male gender, but not associated with age. Association of ALT with BMI was more prominent in males than in females. Upper limit of normal for non-overweight women (BMI of less than 25) was 34 U/L,and for non-overweight men was 40 U/L.CONCLUSION: Serum ALT is strongly associated with sex and BMI. The normal range of ALT should be defined for male and female separately.展开更多

However,sequential follow-up of liver biochemical data remained lacking..METHODS: The biochemistry data and clinical symptoms of 11 sporadic patients were collected and analyzed, focusing on the impacts of leptospirosis upon liver biochemistry tests.RESULTS: The results disclosed that of the 11 cases, 5 or 45% died. The liver biochemistry data in the beginning of the disease course were only mildly elevated.Nevertheless, late exaggerated aspartate transaminase (AST)elevations were noted in three cases who finally died when compared with the typical course. Besides, significant higher AST/alanine transaminase (ALT) ratios (AARs) of the peak levels for transaminase were also noted in the cases who eventually succumbed. The mean±SD of AARs for the survival group and dead group were 5.65±2.27 (n = 5)and 1.86±0.64 (n = 6) respectively (P= 0.006). The ratios of the cases who finally died were all more than 3.0.Conversely, the survival group's ratios were less than 3.0.CONCLUSION: Serial follow-up of transaminase might provide evidence to predict some rare evolutions in leptospirosis. If AST elevated progressively without a concomitant change of ALT, it might indicate an acute disease course with ensuing death. Additionally, AAR is another prognostic parameter for leptospirosis. Once the value was higher than 3.0, a grave prognosis is inevitable.展开更多

METHODS:We enrolled a total of 1308 male workers aged from 22 to 63 years.Data was extracted from the workers'periodic health check-ups in hospitals.All cases were from the community of northern Taiwan. This was a cross-sectional observational study from July to September in 2004.We grouped all cases into four groups,based on the quartile of homeostasis model assessment.The top fourth quartile group was defined as the group with insulin resistance.We performed multivariate logistic regression analysis for the odds ratio of the risk factors for insulin resistance. RESULTS:Compared with metabolic syndrome,the coexistence of both factors had a 4.3-fold(95%CI: 2.7-6.8)increased risk,which was more than metabolic syndrome with a 3.6-fold(95%CI:2.6-5.0)increased risk.The two factors had a synergistic effect.The synergistic index of obesity and elevated alanine aminotransferase(ALT)was 2.1(95%CI:1.01-4.3).CONCLUSION:Obesity and elevated ALT are associatedwith insulin resistance.The effects are synergistic. Coexistence of them is better than metabolic syndrome in predicting insulin resistance.展开更多

文摘目的评估内镜序贯经颈静脉肝内门体分流术(TIPS)治疗肝硬化急性食管胃静脉曲张破裂出血(EGVB)的安全性及有效性。方法将2019年9月—2021年3月接受内镜序贯TIPS治疗的肝硬化急性EGVB 31例作为内镜序贯TIPS组,将接受单纯内镜序贯治疗的46例作为内镜序贯组。观察内镜序贯TIPS组门静脉压力梯度变化情况,比较2组静脉曲张改善程度及肝功能变化,术后1、3、6、12个月再出血率及肝性脑病发生率,随访结束后分析2组生存情况。结果内镜序贯TIPS组术后门静脉压力梯度低于术前(P<0.01)。内镜序贯TIPS组术后丙氨酸转氨酶(ALT)、天冬氨酸转氨酶(AST)术后1个月高于其他时点(P<0.05),术后3个月开始下降;内镜序贯TIPS组术后血清胆红素升高,术后3个月直接胆红素(DBIL)和间接胆红素(IBIL)升至高峰,术后6个月逐渐下降(P<0.05)。内镜序贯组术后3、7 d ALT、AST较术前降低,ALB较术前升高(P<0.05);术后1个月总胆红素(TBIL)水平低于术前(P<0.05);术后7 d及术后1、3个月DBIL低于术前(P<0.05)。2组术后静脉曲张根除率比较差异无统计学意义(P>0.05)。内镜序贯TIPS组术后6、12个月再出血率低于内镜序贯组(P<0.01);2组术后肝性脑病发生率及术后1年生存率比较差异均无统计学意义(P>0.05)。结论TIPS可降低门静脉压力,静脉曲张根除率与内镜序贯治疗相当,但可有效降低再出血率,而并不降低生存率且不增加肝性脑病发生率。内镜序贯TIPS治疗肝硬化EVGB安全有效。
