| 1 | Combined acoustic radiation force impulse, aminotransferase to platelet ratio index and Forns index assessment for hepatic fibrosis grading in hepatitis B显示文摘AIM: To investigate the combined diagnostic accuracy of acoustic radiation force impulse(ARFI), aspartate aminotransferase to platelet ratio index(APRI) and Forns index for a non-invasive assessment of liver fibrosis in patients with chronic hepatitis B(CHB). METHODS: In this prospective study, 206 patients had CHB with liver fibrosis stages F0-F4 classified by METAVIR and 40 were healthy volunteers were measured by ARFI, APRI and Forns index separately or combined as indicated. RESULTS: ARFI, APRI or Forns index demonstrated a significant correlation with the histological stage(all P < 0.001). According to the AUROC of ARFI and APRI for evaluating fibrotic stages more than F2, ARFI showed an enhanced diagnostic accuracy than APRI(P < 0.05). The combined measurement of ARFI and APRI exhibited better accuracy than ARFI alone when evaluating ≥ F2 fibrotic stage(Z = 2.77, P = 0.006). Combination of ARFI, APRI and Forns index did not obviously improve the diagnostic accuracy compared to the combination of ARFI and APRI(Z = 0.958, P = 0.338). CONCLUSION: ARFI + APRI showed enhanced diagnostic accuracy than ARFI or APRI alone for significant liver fibrosis and ARFI + APRI + Forns index shows the same effect with ARFI + APRI. | Chang-Feng Dong Jia Xiao Ling-Bo Shan Han-Ying Li Yong-Jia Xiong Gui-Lin Yang Jing Liu Si-Min Yao Sha-Xi Li Xiao-Hua Le Jing Yuan Bo-Ping Zhou George L Tipoe Ying-Xia Liu | 2016 | World Journal of Hepatology2016，8，14： | 18 |
| 2 | Predictive factors for survival and score application in liver retransplantation for hepatitis C recurrence显示文摘AIM: To identify risk factors associated with survival in patients retransplanted for hepatitis C virus(HCV) recurrence and to apply a survival score to this population.METHODS: We retrospectively identified 108 patients retransplanted for HCV recurrence in eight European liver transplantation centers(seven in France, one in Spain). Data collection comprised clinical and laboratory variables, including virological and antiviral treatment data. We then analyzed the factors associated with survival in this population. A recently published score that predicts survival in retransplantation in patients with hepatitis C was applied. Because there are currently no uniform recommendations regarding selection of the best candidates for retransplantation in this setting, we also described the clinical characteristics of 164 patients not retransplanted, with F3, F4, or fibrosing cholestatic hepatitis(FCH) post-first graft presenting with hepatic decompensation. RESULTS: Overall retransplantation patient survival rates were 55%, 47%, and 43% at 3, 5, and 10 years, respectively. Patients who were retransplanted for advanced cirrhosis had survival rates of 59%, 52%, and 49% at 3, 5, and 10 years, while those retransplanted for FCH had survival rates of 34%, 29%, and 11%, respectively. Under multivariate analysis, and adjusting for the center effect and the occurrence of FCH, factors associated with better survival after retransplantation were: negative HCV viremia before retransplantation, antiviral therapy after retransplantation, non-genotype 1, a Model for End-stage Liver Disease(MELD) score < 25 when replaced on the waiting list, and a retransplantation donor age < 60 years. Although the numbers were small, in the context of the new antivirals era, we showed that outcomes in patientswho underwent retransplantation with undetectable HCV viremia did not depend on donor age and MELD score. The Andrés score was applied to 102 patients for whom all score variables were available, producing a mean score of 43.4(SD = 6.6). Survival rates after the date of the first decompensation post-first liver transplantation(LT1) in the liver retransplantation(re LT) group(94 patients decompensated) at 3, 5, and 10 years were 62%, 59%, and 51%, respectively, among 78 retransplanted individuals with advanced cirrhosis, and 42%, 32%, and 16% among 16 retransplanted individuals with FCH. In the non-re LT group with hepatic decompensation, survival rates were 27%, 18%, and 9% at 3, 5, and 10 years, respectively(P < 0.0001). Compared with non-retransplanted patients, retransplanted patients were younger at LT1(mean age 48 ± 8 years compared to 53 ± 9 years in the no re LT group, P < 0.0001), less likely to have human immunodeficiency virus(HIV) co-infection(4% vs 14% among no re LT patients, P = 0.005), more likely to have received corticosteroid bolus therapy after LT1(25% in re LT vs 12% in the no re LT group, P = 0.01), and more likely to have presented with sustained virological response(SVR) after the first transplantation(20% in the re LT group vs 7% in the no re LT group, P = 0.028).CONCLUSION: Antiviral therapy before and after retransplantation had a substantial impact on survival in the context of retransplantation for HCV recurrence, and with the new direct-acting antivirals now available, outcomes should be even better in the future. | Alice Tung Wan Song Rodolphe Sobesky Carmen Vinaixa Jérome Dumortier Sylvie Radenne Francois Durand Yvon Calmus Géraldine Rousseau Marianne Latournerie Cyrille Feray Valérie Delvart Bruno Roche Stéphanie Haim-Boukobza Anne-Marie Roque-Afonso Denis Castaing Edson Abdala Luiz Augusto Carneiro D’Albuquerque Jean-Charles Duclos-Vallée Marina Berenguer Didier Samuel | 2016 | World Journal of Gastroenterology2016，22，18： | 1 |
| 3 | Aberrant post-translational protein modifications in the pathogenesis of alcohol-induced liver injury显示文摘It is likely that the majority of proteins will undergo post-translational modification, be it enzymatic or non-enzymatic. These modified protein(s) regulate activity, localization and interaction with other cellular molecules thereby maintaining cellular hemostasis. Alcohol exposure significantly alters several of these post-translational modifications leading to impairments of many essential physiological processes. Here, we present new insights into novel modifications following ethanol exposure and their role in the initiation and progression of liver injury. This critical review condenses the proceedings of a symposium at the European Society for the Biomedical Research on Alcoholism Meeting held September 12-15, 2015, in Valencia, Spain. | Natalia A Osna Wayne G Carter Murali Ganesan Irina A Kirpich Craig J Mc Clain Dennis R Petersen Colin T Shearn Maria L Tomasi Kusum K Kharbanda | 2016 | World Journal of Gastroenterology2016，22，27： | 1 |
