| 1 | Translational approaches: From fatty liver to non-alcoholic steatohepatitis显示文摘Over the past few decades, non-alcoholic fatty liver disease(NAFLD) has become one, if not the most common,cause of chronic liver disease affecting both adults and children. The increasing number of cases at an early age is the most worrying aspect of this pathology, since it provides more time for its evolution. The spectrum of this disease ranges from liver steatosis to steatohepatitis, fibrosis and in some cases, hepatocellular carcinoma. NAFLD may not always be considered a benign disease and hepatologists must be cautious in the presence of fatty liver. This should prompt the use of the available experimental models to understand better the pathogenesis and to develop a rational treatment of a disease that is dangerously increasing. In spite of the growing efforts, the pathogenesis of NAFLD is still poorly understood. In the present article we review the most relevant hypotheses and evidence that account for the progression of NAFLD to non-alcoholic steatohepatitis(NASH) and fibrosis. The available in vitro and in vivo experimental models of NASH are discussed and revised in terms of their validity in translational studies. These studies must be aimed at the discovery of the still unknown triggers or mediators that induce the progression of hepatic inflammation, apoptosis and fibrosis. | Natalia Rosso Norberto C Chavez-Tapia Claudio Tiribelli Stefano Bellentani | 2014 | World Journal of Gastroenterology2014，20，27： | 14 |
| 2 | Serum leptin levels and insulin resistance are associated with gallstone disease in overweight subjects显示文摘AIM: To establish an association between the serum leptin levels and the development of gallstone disease (GD).METHODS: We carried out a non-matched case-controlled study in a university hospital in Mexico City. Two hundred and eighty-seven subjects were included: 97 cases with gallstones and 190 controls. Body mass index (BMI), fasting plasma leptin, insulin, serum lipid, and lipoprotein levels were measured. Insulin resistance was calculated by homeostasis model assessment (HOMA-IR). Unconditional logistic regression analysis (univariate and multivariate)stratified by BMI was used to calculate the risk of GD.RESULTS: The multivariate conditional regression analysis revealed a model for those patients with BMI <30. The selected variables in the model were HOMA-IR index with OR = 1.31, P= 0.02 and leptin higher than median with OR = 2.11, P= 0.05. In the stratum of BMI ≥30, we did not find a useful model.CONCLUSION: We concluded that insulin resistance and the development of GD appears to be associated with serum leptin levels in subjects with overweight, but not in obese subjects with similar metabolic profiles. | Nahum Méndez-Sánchez Luisa B Bermejo-Martínez Yolanda Vi(n|~)als Norberto C Chavez-Tapia Irina Vander Graff Guadalupe Ponciano-Rodríguez Martha H Ramos Misael Uribe | 2005 | World Journal of Gastroenterology2005，11，39： | 11 |
| 3 | Insulin sensitizers in treatment of nonalcoholic fatty liver disease:Systematic review显示文摘AIM: To summarize the evidence available for the clinical effectiveness of insulin sensitizers in the treatment of nonalcoholic fatty liver disease (NAFLD) systematically. METHODS: Relevant articles were located using computer-assisted searches of Medline (1966-March 2006), EMBASE (1988-March 2006), CINAHL (1982-March 2003), Educational Resource Information Center (1966-March 2006), Library, Information Science & Technology Abstracts (1967-March 2006), Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects (1994-2006), dissertations in ProQuest and FirstSearch databases. Manual searches were made in the abstracts from meetings of the American Gastroenterological Association (1999-2006), and the American Association for the Study of Liver Diseases (2003-2005). Studies were retrieved using the following selection criteria: (1) clinical trials using insulin sensitizers in subjects with NAFLD, (2) adult patients, (3) published as full manuscripts or abstracts, and (4) English, Spanish, German, and French languages only. Data were abstracted independently by two reviewers following standardized procedures. A face-to- face comparison of data was conducted to ensure the completeness and reliability of the abstraction process. RESULTS: Nine studies were included, six using metformin and three using thiazolidinediones. Only two studies were placebo-controlled trials. The mediansample size for all studies was 18 subjects. In the placebo-controlled trials, metformin improved insulin resistance markers and liver function tests, but not histological scores. In the single-arm trials, metformin and thiazolidinediones improved insulin resistance markers and liver function tests, and beneficial histological changes were reported. There is limited high-quality information available from which to draw categorical conclusions about the clinical use of insulin sensitizers in NAFLD.CONCLUSION: Current information indicates that the use of insulin sensitizers in NAFLD improves insulin resistance and liver function. Histological changes must be corroborated in randomized controlled trials. | Norberto C Chavez-Tapia Tonatiuh Barrientos-Gutierrez Felix I Tellez-ávila Francisco Sánchez-ávila Maria Antonieta Montao-Reyes Misael Uribe | 2006 | World Journal of Gastroenterology2006，12，48： | 11 |
| 4 | PPIs are not associated with a lower incidence of portal-hypertension-related bleeding in cirrhosis显示文摘AIM:To determine if proton pump inhibitor use in cirrhotic patients with endoscopic findings of portal hypertension is associated with a lower frequency of gastrointestinal bleeding.METHODS:Patients with cirrhosis and endoscopic findings related to portal hypertension,receiving or not receiving proton pump inhibitor (PPI) therapy,were included retrospectively.We assigned patients to two groups:group 1 patients underwent PPI therapy and group 2 patients did not undergo PPI therapy.RESULTS:One hundred and five patients with a median age of 58 (26-87) years were included,57 (54.3%) of which were women.Esophageal varices were found in 82 (78%) patients,portal hypertensive gastropathy in 72 (68.6%) patients,and gastric varices in 15 (14.3%) patients.PPI therapy was used in 45.5% of patients (n=48).Seventeen (16.1%) patients presented with upper gastrointestinal bleeding;in 14/17 (82.3%) patients,bleeding was secondary to esophageal varices,and in 3/17 patients bleeding was attributed to portal hypertensive gastropathy.Bleeding related to portal hypertension according to PPI therapy occurred in 18.7% (n=9) of group 1 and in 14% (n=8) of group 2 (odds ratio:0.83,95% confidence interval:0.5-1.3,P=0.51).CONCLUSION:Portal hypertension bleeding is not associated with PPI use.These findings do not support the prescription of PPIs in patients with chronic liver disease with no currently accepted indication. | Mauricio Garcia-Saenz-de-Sicilia Francisco Sanchez-Avila Norberto C Chavez-Tapia Gustavo Lopez-Arce Sandra Garcia-Osogobio Roberto Ruiz-Cordero Felix I Tellez-Avila | 2010 | World Journal of Gastroenterology2010，16，46： | 6 |
| 5 | Prevalence of metabolic syndrome, obesity and diabetes type 2 in cryptogenic cirrhosis显示文摘AIM: To evaluate the prevalence of metabolic syndrome (MS), obesity and type 2 diabetes mellitus (T2DM) in a group of Mexican Mestizo patients with cryptogenic cirrhosis (CC) and to compare this group with patients with cirrhosis secondary to other causes (disease controls). METHODS: Patients with CC, diagnosed between January, 1990 and April, 2005, were included in a retrospective study. Patients with cirrhosis caused by chronic hepatitis C, alcohol abuse or autoimmune hepatitis (AIH) served as disease controls. RESULTS: A total of 134 patients with CC were analyzed. Disease controls consisted of 81 patients with chronic hepatitis C, 33 with alcohol abuse and 20 with AIH. The median age of patients with CC was 57 years (range, 16-87); 83 (61.9%) patients were female; 53 (39.6%) were Child A, 65 (48.5%) Child B, and 16 (11.9%) were Child C cirrhosis. The prevalence of MS (29.1% vs 6%; P < 0.001), obesity (16.4% vs 8.2%; P = 0.04) and T2DM (40% vs 22.4%; P = 0.013) was higher in CC patients than in disease controls. There were no differences in sex, age or liver function tests between the two groups. CONCLUSION: The prevalence of MS, obesityand T2DM were higher in patients with CC than in patients with cirrhosis secondary to others causes. Our findings support the hypothesis that non-alcoholic steatohepatitis (NASH) plays an under-recognized role in CC. | Felix I Tellez-Avila Francisco Sanchez-Avila Mauricio García-Saenz-de-Sicilia Norberto C Chavez-Tapia Ada M Franco-Guzman Gustavo Lopez-Arce Eduardo Cerda-Contreras Misael Uribe | 2008 | World Journal of Gastroenterology2008，14，30： | 6 |

| 7 | Clinical heterogeneity in autoimmune acute liver failure显示文摘AIM: To describe the outcome and prognosis in a cohort of patients with acute liver failure due to autoimmune hepatitis without liver transplantation. METHODS: A retrospective trial was conducted in 11 patients with acute liver failure due to autoimmune hepatitis who attended the Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubiran. Demographic, biochemical and severity indexes, and treatment and outcome were assessed. RESULTS: Among the 11 patients, with a median age of 31 years, 72% had inflammatory response syndrome, and six patients received corticosteroids. The mortality rate within four weeks was 56%, and the one-year survival was 27%. In the survivors, severity indexes were lower and 83% received corticosteroids. CONCLUSION: We observed a relatively high survival rate in patients with acute liver failure due to autoimmune hepatitis. This survival rate could be influenced by severity of the disease and/or use of corticosteroids. | Norberto C Chavez-Tapia Julio Martinez-Salgado Julio Granados Misael Uribe Felix I Tellez-Avila | 2007 | World Journal of Gastroenterology2007，13，12： | 1 |
