<b>OBJECTIVEb>To evaluate the renal function in treatment-naive patients with hepatitis B virus (HBV) related cirrhosis and to identify the risk factors for renal impairment.

<b>METHODSb>We collected the data of 860 HBV-related cirrhosis patients hospitalized in our unit between Jan 1, 2011 and Dec 31, 2011. Liver function of the patients was assessed with Child-Pugh score system, and the renal function with estimated glomerular filtration rate (eGFR) calculated by Modification of Diet in Renal Disease (MDRD) equation recommended by Kidney Disease Outcomes Quality Initiative (K/DOQI). We investigated the prevalence of renal impairment (eGFR>60 ml/min/1.73 m(2)) among these patients and explored the risk factors for renal impairment.

<b>RESULTSb>Of the 860 patients, 296 had complete clinical data and were included in our analysis. The overall incidence of renal impairment among the enrolled patients was 8.45% (25/296). Patients with Child-Pugh stage C showed a significantly higher incidence of renal impairment than those with stages B and A (17.17% [17/99] vs 6.67%[7/105] vs 1.09% [1/92], P<0.001). Age, history of hyperuricemia, and Child-Pugh score were identified as the risk factors for renal impairment in these patients.

<b>CONCLUSIONb>In patients with HBV-related liver cirrhosis, the incidence of renal impairment increases significantly with deterioration of the liver function, and renal function should be regularly monitored in these patients for appropriate antiviral treatment.

BACKGROUND/AIMS: The aim of this study was to measure health related quality of life (HRQOL) in patients with chronic viral hepatitis or cirrhosis and to determine factors associated with more severe impairment. METHODS: We conducted a cross-sectional study in which we documented patients' demographic and clinical characteristics and measured their HRQOL using the Korean version of Short Form-36. A total of 375 patients were enrolled in the study. We compared patients' HRQOL with that of 750 participants in a control group and assessed the association of HRQOL impairment with clinical parameters. RESULTS: In all except two domains (physical functioning, bodily pain) of SF-36, HRQOL scores were significantly lower in the patient group than in the control group (p<0.001). The difference was more prominent in those domains reflective of mental, rather than physical, health. When patient group was classified as noncirrhosis, Child A, B, or C according to modified Child-Pugh classification, severe liver disease was associated with a lower HRQOL score. Interestingly, scores of domains reflective of mental health were decreased from the early stage of disease (noncirrhosis or Child-Pugh A). Those of domains reflective of physical health, however, were decreased only in advanced stages of disease (Child-Pugh B or C). There are weak but significant correlations between SF-36 scores and age, serum albumin, serum bilirubin, and prothrombin time, but no correlation with histologic activity, transaminase level, disease duration, virus type (HBV or HCV) and HBV DNA level. CONCLUSIONS: Compared with the control group, patients with chronic viral hepatitis or cirrhosis showed substantial impairment of HRQOL, which is further affected by worsening disease severity. More concern about HRQOL should be warranted in the evaluation of health change due to disease progression or therapeutic trial.

Asymptomatic chronic HBsAg carriers with normal liver function tests are, in general regarded as having no liver pathology. Most of the histologic findings in asymptomatic chronic carriers have been reported from areas with low incidence of Hepatitis B virus (HBV) infection, such as North America and Western Europe. It is well known that there are many differences in HBV infection between low and high endemic areas, but there have been few reports on the histologic findings of asymptomatic chronic HBsAg carriers from endemic areas. The present study was undertaken in Korea which is one of the endemic areas for HBV infection and was designed to assess the prevalence of chronic liver disease by peritoneoscopic liver biopsy among asymptomatic chronic HBsAg carriers and to make a basis for the follow-up of asymptomatic chronic HBsAg carriers according to the results obtained. One hundred and ten asymptomatic HBsAg-positive carriers with normal liver function tests and no hepatomegaly were included in the study. Final diagnosis by peritoneoscopic liver biopsy revealed that of the 110 asymptomatic carriers only 27 (24.5%) had a histologically normal liver, while 51 (46.4%) had chronic liver diseases, and the remaining 32 (29.1%) had nonspecific histologic abnormalities (nonspecific reactive changes in 18 cases, cholestasis in 6 cases, and fatty change in 8 cases). Of the 51 patients with chronic liver diseases, 3 had liver cirrhosis, 4 chronic active hepatitis with cirrhosis, 11 chronic active hepatitis and 33 chronic persistent hepatitis. The frequency of liver cirrhosis and chronic active hepatitis with cirrhosis was significantly high in the over 30 years of age group (12.1%) than in the under 30 years of age group (0%; p = 0.011 by Fisher's exact test). In conclusion, 46.4% of the Korean asymptomatic chronic HBsAg carriers with normal liver function tests and no hepatomegaly had chronic liver disease. This finding contrasted with reports from low incidence areas of HBV infection. Our results suggest that in endemic areas, a liver biopsy should be considered to assess the status of liver disease in asymptomatic chronic HBsAg carriers even if liver function tests are normal and hepatomegaly is absent, and the result can be used as a basis for the follow-up of each asymptomatic chronic HBsAg carriers.

<b>BACKGROUNDb>Acute-on-chronic hepatitis B liver failure (ACLF-HBV) is a clinically severe disease associated with major life-threatening complications including hepatic encephalopathy and hepatorenal syndrome. The aim of this study was to evaluate the short-term prognostic predictability of the model for end-stage liver disease (MELD), MELD-based indices, and their dynamic changes in patients with ACLF-HBV, and to establish a new model for predicting the prognosis of ACLF-HBV.

<b>METHODSb>A total of 172 patients with ACLF-HBV who stayed in the hospital for more than 2 weeks were retrospectively recruited. The predictive accuracy of MELD, MELD-based indices, and their dynamic change (D) were compared using the area under the receiver operating characteristic curve method. The associations between mortality and patient characteristics were studied by univariate and multivariate analyses.

<b>RESULTSb>The 3-month mortality was 43.6%. The largest concordance (c) statistic predicting 3-month mortality was the MELD score at the end of 2 weeks of admission (0.8), followed by the MELD: sodium ratio (MESO) (0.796) and integrated MELD (iMELD) (0.758) scores, DMELD (0.752), DMESO (0.729), and MELD plus sodium (MELD-Na) (0.728) scores. In multivariate Logistic regression analysis, the independent factors predicting prognosis were hepatic encephalopathy (OR = 3.466), serum creatinine, international normalized ratio (INR), and total bilirubin at the end of 2 weeks of admission (OR = 10.302, 6.063, 5.208, respectively), and cholinesterase on admission (OR = 0.255). This regression model had a greater prognostic value (c = 0.85, 95%CI 0.791 - 0.909) compared to the MELD score at the end of 2 weeks of admission (Z = 4.9851, P = 0.0256).

<b>CONCLUSIONSb>MELD score at the end of 2 weeks of admission is a useful predictor for 3-month mortality in ACLF-HBV patients. Hepatic encephalopathy, serum creatinine, international normalized ratio, and total bilirubin at the end of 2 weeks of admission and cholinesterase on admission are independent predictors of 3-month mortality.

<b>OBJECTIVESb>To determine whether -238G/A and -857C/T polymorphisms of tumor necrosis factor-alpha (TNF-alpha) gene promoter were associated with outcomes of hepatitis B virus infection.

<b>METHODSb>A total of 246 HBV self-limited infected subjects and 443 chronic hepatitis B (HB) patients were recruited in this case-control study. TNF-alpha-238G/A and -857C/T gene promoter polymorphisms were examined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP).

<b>RESULTSb>The frequency of TNF-alpha-238 GG (90.7%) in chronic HB group was significantly lower than that (95.1%) in self-limited group (P = 0.041). The frequency of TNF-alpha-857 CC (79.7%) in chronic HB patients was significantly higher than that (70.9%) in self-limited infected subjects (P = 0.021). Multiple logistic regression analysis revealed that both TNF-alpha-238GA and -857CC were independently associated with chronic HB.

<b>CONCLUSIONSb>TNF-alpha promoter variants are likely to play a substantial role in influencing the outcomes of HBV infection.

<b>OBJECTIVEb>To investigate the short-term spontaneous fluctuation of viral load in patients with chronic hepatitis B (CHB) and explore the related factors in treatment naive CHB patients during immune clearance phase.

<b>METHODSb>A total of 123 treatment naive HBeAg-positive CHB patients with ALT>2 × ULN were enrolled in this study. Paired serum samples were obtained at the first and second visits with an interval of less than 4 weeks. The levels of quantitative HBV DNA (Roche COBAS), quantitative HBsAg, ALT and AST were analyzed. Liver biopsy specimen were collected within 4 weeks and evaluated using Knodell and Ishak histological scoring system.

<b>RESULTSb>Of the 123 patients, 93 (75.6%) and 30 (24.4%) had HBV DNA fluctuation ≤ 0.5 Log IU/ml and >0.5 Log IU/ml, respectively. Binary logistic multivariate regression analysis identified Knodell necroinflammation score and HBV DNA level as the factors related to HBV DNA fluctuation. Patients with Knodell necorinflammation score ≥ 10 or HBV DNA<7 Log IU/ml had significantly higher rates of HBV DNA fluctuation>0.5 Log IU/ml (50.0% vs 18.3%, P=0.042; 42.9% vs 20.6%, P=0.030).

<b>CONCLUSIONb>Treatment naive CHB patients in immune clearance phase show short-term spontaneous fluctuation of HBV DNA, and nearly 25% of the patients have HBV DNA fluctuation >0.5 Log IU/ml. Such fluctuation is related to liver inflammation and quantity of HBV DNA.
