2Benefit of combination β-blocker and endoscopic treatment to prevent variceal rebleeding: A meta-analysis显示文摘AIM: To determine whether the association of β-blockers with endoscopic treatment is superior to endoscopic treatment alone for the secondary prophylaxis of oesophageal variceal bleeding. METHODS: Randomised controlled trials comparing sclerotherapy (SCL) with SCL plus β-blockers (BB) or banding ligation (BL) with BL plus BB were identif ied.Main outcomes were overall and 6, 12 and 24 mo rebleeding rates, as well as overall and 6, 12 and 24 mo mortality. Two statistical methods were used: Yusuf-Peto, and Der Simonian and Laird. Inter-trial heterogeneity was systematically taken into account. RESULTS: Seventeen randomised controlled trials were included, 14 with SCL and 3 with BL. Combination β-blocker and endoscopic treatment signif icantly reduced rebleeding rates at 6, 12 and 24 mo and overall [odds ratio (OR): 2.20, 95% conf idence interval (CI): 1.69-2.85, P<0.0001] compared to endoscopic treatment alone. Mortality at 24 mo was signif icantly lower for the combined treatment group (OR: 1.83, 95% CI:1.16-2.90, P= 0.009), as well as overall mortality (OR: 1.43, 95% CI:1.03-1.98, P= 0.03). CONCLUSION: Combination therapy should thus be recommended as the fi rst line treatment for secondary prophylaxis of oesophageal variceal bleeding.Natalie Funakoshi Frédérique Ségalas-Largey Yohan Duny Frédéric Oberti Jean-Christophe Valats Michael Bismuth Jean-Pierre Daurès Pierre Blanc 2010World Journal of Gastroenterology2010,16,47:24

6Genotype phenotype classification of hepatocellular adenoma显示文摘Studies that compare tumor genotype with phenotype have provided the basis of a new histological/molecular classification of hepatocellular adenomas. Based on two molecular criteria (presence of a TCF1/HNF1α or β-catenin mutation), and an additional histological criterion (presence or absence of an inflammatory infiltrate), subgroups of hepatocellular adenoma can be defined and distinguished from focal nodular hyperplasia. Analysis of 96 hepatocellular adenomas performed by a French collaborative network showed that they can be divided into four broad subgroups: the fi rst one is defi ned by the presence of mutations in TCF1 gene inactivating the hepatocyte nuclear factor 1 (HNF1α); the second by the presence of β-catenin activating mutations; the category without mutations of HNF1α or β-catenin is further divided into 2 subgroups depending on the presence or absence of in? ammation. Therefore, the approach to the diagnosis of problematic benign hepatocytic nodules may be entering a new era directed by new molecular information. It is hoped that immunohistological tools will improve significantly diagnosis of liver biopsy in our ability to distinguish hepatocellular adenoma from focal nodular hyperplasia (FNH), and to delineate clinically meaningful entities within each group to define the best clinical management. The optimal care of patients with a liver nodule will benefit from the recent knowledge coming from molecular biology and the combined expertise of hepatologists, pathologists, radiologists, and surgeons.Paulette Bioulac-Sage Jean Frédéric Blanc Sandra Rebouissou Charles Balabaud Jessica Zucman-Rossi 2007World Journal of Gastroenterology2007,13,19:7

11Effect of probiotic administration on the intestinal microbiota, current knowledge and potential applications显示文摘Although it is now known that the human body is colonized by a wide variety of microbial populations in different parts(such as the mouth, pharynx and respiratory system, the skin, the gastro- and urogenital tracts), many effects of the complex interactions between the human host and microbial symbionts are still not completely understood. The dysbiosis of the gastrointestinal tract microbiota is considered to be one of the most important contributing factors in the development of many gastrointestinal diseases such as inflammatory bowel disease, irritable bowel syndrome and colorectal cancer, as well as systemic diseases like obesity, diabetes, atherosclerosis and non-alcoholic fatty liver disease. Fecal microbial transplantations appear to be promising therapies for dysbiosis-associated diseases; however, probiotic microorganisms have been growing in popularity due to increasing numbers of studies proving that certain strains present health promoting properties, among them the beneficial balance of the intestinal microbiota. Inflammatory bowel diseases andobesity are the pathologies in which there are more studies showing this beneficial association using animal models and even in human clinical trials.In this review,the association of the human gut microbiota and human health will be discussed along with the benefits that probiotics can confer on this symbiotic activity and on the prevention or treatment of associated diseases.Alejandra de Moreno de Le Blanc Jean Guy Le Blanc 2014World Journal of Gastroenterology2014,20,44:5

15Clinical epidemiology of chronic viral hepatitis B:A Tuscany real-world large-scale cohort study显示文摘AIM To build a regional database of chronic patients to define the clinical epidemiology of hepatitis B virus(HBV)-infected patients in the Tuscan public health care system.METHODS This study used a cross-sectional cohort design. We evaluated chronic viral hepatitis patients with HBV referred to the outpatient services of 16 hospital units. Information in the case report forms included main demographic data, blood chemistry data, viral hepatitis markers, instrumental evaluations, and eligibility for treatment or ongoing therapy and liver transplantation. RESULTS Of 4015 chronic viral hepatitis patients, 1096(27.3%) were HBV infected. The case report form was correctly completed for only 833 patients(64% males, 36% females; mean age 50.1 ± 15.4). Of these HBV-infected patients, 73% were Caucasian, 21% Asian, 4% Central African, 1% North African and 1% American. Stratifying patients by age and nationality, we found that 21.7% of HBV-infected patients were aged < 34 years(only 2.8% were Italian). The most represented routes of transmission were nosocomial/dental procedures(23%), mother-to-child(17%) and sexual transmission(12%). The most represented HBV genotypes were D(72%) and A(14%). Of the patients, 24.7% of patients were HBe Ag positive, and 75.3% were HBe Ag negative. Of the HBV patients 7% were anti-HDV positive. In the whole cohort, 26.9% were cirrhotic(35.8% aged < 45 years), and 47% were eligible for or currently undergoing treatment, of whom 41.9 % were cirrhotic. CONCLUSION Only 27.3% of chronic viral hepatitis patients were HBV infected. Our results provide evidence of HBV infection in people aged < 34 years, especially in the foreign population not protected by vaccination. In our cohort of patients, liver cirrhosis was also found in young adults.Cristina Stasi Caterina Silvestri Roberto Berni Maurizia Rossana Brunetto Anna Linda Zignego Cristina Orsini Stefano Milani Liana Ricciardi Andrea De Luca Pierluigi Blanc Cesira Nencioni Donatella Aquilini Alessandro Bartoloni Giampaolo Bresci Santino Marchi Franco Filipponi Piero Colombatto Paolo Forte Andrea Galli Sauro Luchi Silvia Chigiotti Alessandro Nerli Giampaolo Corti Rodolfo Sacco Paola Carrai Angelo Ricchiuti Massimo Giusti Paolo Almi Andrea Cozzi Silvia Carloppi Giacomo Laffi Fabio Voller Francesco Cipriani 2018World Journal of Hepatology2018,10,5:3
