| 1 | Effect of transjugular intrahepatic portosystemic shunt on pulmonary gas exchange in patients with portal hypertension and hepatopulmonary syndrome显示文摘AIM: To assess the impact of transjugular intrahepatic portosystemic shunt (TIPS) on pulmonary gas exchange and to evaluate the use of TIPS for the treatment of hepatopulmonary syndrome (HPS).METHODS: Seven patients, three of them with advanced HPS, in whom detailed pulmonary function tests were performed before and after TIPS placementat the University of Alabama Hospital and at the Hospital Clinic, Barcelona, were considered.RESULTS: TIPS patency was confirmed by hemodynamic evaluation. No changes in arterial blood gases were observed in the overall subset of patients. Transient arterial oxygenation improvement was observed in only one HPS patient, early after TIPS, but this was not sustained 4 mo later.CONCLUSION: TIPS neither improved nor worsened pulmonary gas exchange in patients with portal hypertension. This data does not support the use of TIPS as a specific treatment for HPS. However, it does reinforce the view that TIPS can be safely performed for the treatment of other complications of portal hypertension in patients with HPS. | Graciela Martínez-Pallí Britt B Drake Joan-Carles García-Pagán Joan-Albert Barberà Miguel R Arguedas Robert Rodriguez-Roisin Jaume Bosch Michael B Fallon | 2005 | World Journal of Gastroenterology2005，11，43： | 11 |
| 2 | Gender and racial differences in nonalcoholic fatty liver disease显示文摘Due to the worldwide epidemic of obesity, nonalcoholic fatty liver disease(NAFLD) has become the most com-mon cause of elevated liver enzymes. NAFLD represents a spectrum of liver injury ranging from simple steato-sis to nonalcoholic steatohepatitis(NASH) which may progress to advanced fibrosis and cirrhosis. Individuals with NAFLD, especially those with metabolic syndrome, have higher overall mortality, cardiovascular mortality, and liver-related mortality compared with the general population. According to the population-based studies, NAFLD and NASH are more prevalent in males and in Hispanics. Both the gender and racial ethnic differences in NAFLD and NASH are likely attributed to interaction between environmental, behavioral, and genetic fac-tors. Using genome-wide association studies, several genetic variants have been identified to be associated with NAFLD/NASH. However, these variants account for only a small amount of variation in hepatic steatosis among ethnic groups and may serve as modifiers of the natural history of NAFLD. Alternatively, these variants may not be the causative variants but simply markers representing a larger body of genetic variations. In this article, we provide a concise review of the gender and racial differences in the prevalence of NAFLD and NASHin adults. We also discuss the possible mechanisms for these disparities. | Jen-Jung Pan Michael B Fallon | 2014 | World Journal of Hepatology2014，6，5： | 10 |
| 3 | Vanishing bile duct syndrome in human immunodeficiency virus: Nevirapine hepatotoxicity revisited显示文摘Vanishing bile duct syndrome (VBDS) refers to a group of disorders characterized by prolonged cholestasis as a result of destruction and disappearance ofintrahepatic bile ducts. Multiple etiologies have been indentifi ed including infections, neoplastic disorders, autoimmune conditions and drugs. The natural history of this condition is variable and may involve resolution of cholestasis or progression with irreversible damage. VBDS is extremely rare in human immunodeficiency virus (HIV)-infected patients and anti-retroviral therapy has never been implicated as a cause. We encountered a young pregnant female with HIV and VBDS secondary to anti-retroviral therapy. Here, we report her clinical course and outcome. | Rajan Kochar Moises I Nevah Frank J Lukens Michael B Fallon Victor I Machicao | 2010 | World Journal of Gastroenterology2010，16，26： | 6 |

| 13 | 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 |
