| 1 | Insulin resistance and liver steatosis in chronic hepatitis C infection genotype 3显示文摘Hepatitis C virus(HCV) infection is a common chronic liver disease worldwide.Non-alcoholic fatty liver disease and insulin resistance(IR) are the major determinants of fibrosis progression and response to antiviral therapy.The pathogenetic link between IR and chronic HCV infection is complex,and is associated with HCV genotype.Liver steatosis is the most common in the patients infected with genotype 3 virus,possibly due to direct effects of genotype 3 viral proteins.To the contrary,hepatic steatosis in the patients infected with other genotypes is thought to be mostly due to the changes in host metabolism,involving IR.In HCV genotype 3,liver steatosis correlates with viral load,reverts after reaching the sustained virologic response and reoccurs in the relapsers.A therapeutic strategy to improve IR and liver steatosis and subsequently the response to antiviral treatment in these patients is warranted. | Ludovico Abenavoli Mario Masarone Valentina Peta Natasa Milic Nazarii Kobyliak Samir Rouabhia Marcello Persico | 2014 | World Journal of Gastroenterology2014，20，41： | 7 |
| 2 | Alimentary regimen in non-alcoholic fatty liver disease:Mediterranean diet显示文摘Non-alcoholic fatty liver disease(NAFLD)is the most common liver disease worldwide.The mechanisms of the underlying disease development and progression are awaiting clarification.Insulin resistance and obesity-related inflammation status,among other possible genetic,dietary,and lifestyle factors,are thought to play the key role.There is no consensus concerning the pharmacological treatment.However,the dietary nutritional management to achieve weight loss is an essential component of any treatment strategy.On the basis of its components,the literature reports on the effectiveness of the Mediterranean diet in reducing cardiovascular risk and in preventing major chronic diseases,including obesity and diabetes.New evidence supports the idea that the Mediterranean diet,associated with physical activity and cognitive behaviour therapy,may have an important role in the prevention and the treatment of NAFLD. | Ludovico Abenavoli Natasa Milic Valentina Peta Francesco Alfieri Antonino De Lorenzo Stefano Bellentani | 2014 | World Journal of Gastroenterology2014，20，45： | 7 |
| 3 | Role of endoscopy in management of gastrointestinal complications of portal hypertension显示文摘The management of patients with gastrointestinal complications of portal hypertension is often complex and challenging. The endoscopy plays an important role in the management of these patients. The role of endoscopy is both diagnostic and interventional and in the last years the techniques have undergone a rapid expansion with the advent of different and novel endoscopic modalities, with consequent improvement of investigation and treatment of these patients. The choice of best therapeutic strategy depends on many factors: baseline disease, patient's clinical performance and the timing when it is done if in emergency or a prophylactic approaches. In this review we evaluate the endoscopic management of patients with the gastrointestinal complications of portal hypertension. | Carmelo Luigiano Giuseppe Iabichino Antongiulio Judica Clara Virgilio Valentina Peta Ludovico Abenavoli | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，1： | 5 |
| 4 | Adiponectin serum level in chronic hepatitis C infection and therapeutic profile显示文摘Hepatic steatosis is commonly seen in the patients with chronic hepatitis C virus(HCV) infection. HCV is closely associated with lipid metabolism,and viral steatosis is more common in genotype 3 infection owing to a direct cytopathic effect of HCV core protein. In non-genotype3 infection,hepatic steatosis is considered largely to be the result of the alterations in host metabolism; metabolic steatosis is primarily linked with HCV genotype 1. A d i p o s e t i s s u e s e c r e t e s d i f f e r e n t h o r m o n e s involved in glucose and lipid metabolisms. It has been demonstrated that adipocytokines are involved in the pathogenesis of non-alcoholic fatty liver disease,as the decreased plasma adiponectin levels,a soluble matrix protein expressed by adipoctyes and hepatocyte,are associated with liver steatosis. Various studies have shown that steatosis is strongly correlated negatively with adiponectin in the patients with HCV infection. The role of adiponectin in hepatitis C virus induced steatosis is still not completely understood,but the relationship between adiponectin low levels and liver steatosis is probably due to the ability of adiponectin to protect hepatocytes from triglyceride accumulation by increasing β-oxidation of free fatty acid and thus decreasing de novo free fatty acid production. | Valentina Peta Carlo Torti Natasa Milic Alfredo Foca Ludovico Abenavoli | 2015 | World Journal of Hepatology2015，7，1： | 4 |
