          Abstract

          Aims. To develop a noninvasive score model to predict NASH in patients with combined CHB and NAFLD. Objective and Methods. 65 CHB patients with NAFLD were divided into NASH group (34 patients) and non-NASH group (31 patients) according to the NAS score. Biochemical indexes, liver stiffness, and Controlled Attenuation Parameter (CAP) were determined. Data in the two groups were compared and subjected to multivariate analysis, to establish a score model for the prediction of NASH. Results. In the NASH group, ALT, TG, fasting blood glucose (FBG), M30 CK-18, CAP, and HBeAg positive ratio were significantly higher than in the non-NASH group ( P < 0.05). Multivariate analysis showed that CK-18 M30, CAP, FBG, and HBVDNA level were independent predictors of NASH. Therefore, a new model combining CK18 M30, CAP, FBG, and HBVDNA level was established using logistic regression. The AUROC curve predicting NASH was 0.961 (95% CI: 0.920–1.00, cutoff value is 0.218), with a sensitivity of 100% and specificity of 80.6%. Conclusion. A noninvasive score model might be considered for the prediction of NASH in patients with CHB combined with NAFLD.

          Global challenges in liver disease.

          Immigration, cheap air travel, and globalization are all factors contributing to a worldwide spread of hepatitis B virus (HBV) and hepatitis C virus (HCV) infection. End-stage chronic liver disease (ESLD) as a result of co-infection with HBV/HCV is now the major cause of death for individuals who have been infected with the HIV virus. The high incidence of HCV infection in Egypt--the legacy left from the mass use of tartar emetic to eradicate schistosomiasis, as in other high prevalence areas--will take years to reduce. Steatohepatitis due to non-alcoholic fatty liver disease is developing into a new and major health problem as a result of rising levels of obesity in populations worldwide. Hepatic steatosis also has an adverse influence on the progression of other liver diseases including chronic HCV infection and alcoholic liver disease. In many countries, considerable public concern is on the rise due to increased levels of alcohol consumption adversely affecting younger and affluent age groups. With the rising prevalence of cirrhosis, primary hepatocellular carcinoma (HCC) is increasing in frequency as is that of primary intrahepatic cholangiocarcinoma. Finally, despite the successes of liver transplantation, many deserving patients are not getting transplants due to low levels of cadaver organ donation in many countries, thereby increasing pressures on the use of living donor liver transplantation. Only through a concerted effort from governments, health agencies, healthcare professionals at all levels, and the pharmaceutical industry can this grim outlook for liver disease worldwide be reversed.

            Non-invasive diagnosis of liver steatosis using controlled attenuation parameter (CAP) and transient elastography.

            Recently, a study showed that Controlled Attenuation Parameter (CAP), evaluated with transient elastography, could efficiently separate steatosis grades. The aim of this study was to prospectively evaluate the performance of CAP for the diagnosis of steatosis in patients with chronic liver disease. Consecutive patients with chronic liver disease had steatosis diagnosis using CAP, blood sample and liver biopsy. Steatosis was graded as the percentage of hepatocytes with fat: S0 ≤ 10%, S1: 11 ~ 33%, S2: 34 ~ 66%, S3 ≥ 67%. Characteristics of the 112 patients included were as follows: age 54 years, BMI 26 kg m(-) ², HCV 36%, NAFLD 25%. Steatosis repartition was: S0 52%, S1 19%, S2 14%, S3 15%. CAP was significantly correlated with SteatoTest, Fatty Liver Index (FLI), percentage of steatosis on liver biopsy, steatosis grade and slightly with liver stiffness, but not with fibrosis and activity grade on liver biopsy. Using CAP vs SteatoTest vs FLI score, Area Under the Receiver-Operating Characteristics (ROC) curves (AUROC)s were 0.84 vs 0.72 vs 0.72 for the diagnosis of steatosis ≥ S1, 0.86 vs 0.73 vs 0.71 for the diagnosis of steatosis ≥ S2, and 0.93 vs 0.73 vs 0.75 for the diagnosis of steatosis S3 respectively. For a sensitivity ≥ 90%, cut-offs of CAP were 215 dB m(-1) for S ≥ 1, 252 dB m(-1) for S ≥ 2, and 296 dB m(-1) for S3. CAP is very efficient to detect even low grade steatosis. CAP being implemented on FibroScan(®) (Echosens, Paris, France), both steatosis and fibrosis can be evaluated simultaneously, enlarging the spectrum of non-invasive techniques for the management of chronic liver diseases. © 2012 John Wiley & Sons A/S.

              Evidence-based clinical practice guidelines for nonalcoholic fatty liver disease/nonalcoholic steatohepatitis.

              Nonalcoholic fatty liver disease (NAFLD) is currently the most common cause of chronic liver disease in industrialized countries worldwide, and has become a serious public health issue not only in Western countries but also in many Asian countries including Japan. Within the wide spectrum of NAFLD, nonalcoholic steatohepatitis (NASH) is a progressive form of disease, which often develops into liver cirrhosis and increases the risk of hepatocellular carcinoma. In turn, a large proportion of NAFLD/NASH is the liver manifestation of metabolic syndrome, suggesting that NAFLD/NASH plays a key role in the pathogenesis of systemic atherosclerotic diseases. Currently, a definite diagnosis of NASH requires liver biopsy, though various noninvasive measures are under development. The mainstays of prevention and treatment of NAFLD/NASH include dietary restriction and exercise; however, pharmacological approaches are often necessary. Currently, vitamin E and thiazolidinedione derivatives are the most evidence-based therapeutic options, although the clinical evidence for long-term efficacy and safety is limited. This practice guideline for NAFLD/NASH, established by the Japanese Society of Gastroenterology in cooperation with The Japan Society of Hepatology, covers lines of clinical evidence reported internationally in the period starting from 1983 to January 2012, and each clinical question was evaluated using the GRADE system. Based on the primary release of the full version in Japanese, this English summary provides the core essentials of this clinical practice guideline comprising the definition, diagnosis, and current therapeutic recommendations for NAFLD/NASH in Japan.
