Profiles associated with significant hepatic fibrosis consisting of alanine aminotransferase >30 U/L, exercise habits, and metabolic dysfunction-associated steatotic liver disease. Hepatol Res 2024; 54:655-666. [PMID: 38294999 DOI: 10.1111/hepr.14020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/05/2023] [Revised: 12/26/2023] [Accepted: 01/16/2024] [Indexed: 02/02/2024]
Abstract
AIM In patients with steatotic liver disease (SLD), significant hepatic fibrosis is a prognostic factor with various etiologies, including inflammation and metabolic dysfunction. This study aimed to investigate independent factors and profiles associated with significant hepatic fibrosis, including alanine aminotransferase (ALT) levels >30 U/L and metabolic dysfunction-associated SLD (MASLD), in health check-up examinees. METHODS This single-center, retrospective, observational cohort study enrolled 1378 consecutive health checkup examinees from April 2018 to September 2022. Shear wave elastography (SWE) was performed during a routine ultrasound examination, and patients with liver stiffness ≥6.60 kPa were defined as having significant hepatic fibrosis. Patients were classified into nonsignificant hepatic fibrosis (n = 1220) or a significant hepatic fibrosis (n = 158) group according to this definition. RESULTS In multivariate analysis, the independent factor for significant hepatic fibrosis was aging (≥65 years; OR 9.637, 95% CI 6.704-13.852, p < 0.0001). According to decision tree analysis, the initial classifier was aging (≥65 years). After aging, an ALT level >30 U/L was the second relevant factor for significant hepatic fibrosis, regardless of age. An undirected graphical model showed that an ALT level of >30 U/L was directly associated with significant hepatic fibrosis. In patients aged ≥65 years with an ALT level >30 U/L, significant hepatic fibrosis was observed in 52% of the patients. Meanwhile, in patients aged ≥65 years with an ALT level ≤30 U/L, MASLD was the third classifier, with significant hepatic fibrosis observed in 38% of patients. CONCLUSIONS ALT levels >30 U/L and MASLD may be involved in the pathogenesis of significant hepatic fibrosis in patients aged ≥65 years.

Zhang B, Zhou Y, Guo J. Association of volatile methylsiloxanes exposure with non-alcoholic fatty liver disease among Chinese adults. ENVIRONMENTAL POLLUTION (BARKING, ESSEX : 1987) 2023; 334:122128. [PMID: 37399934 DOI: 10.1016/j.envpol.2023.122128] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/05/2022] [Revised: 05/08/2023] [Accepted: 06/28/2023] [Indexed: 07/05/2023]
Abstract
Owing to the wide use of volatile methylsiloxanes (VMSs) in various industries and consumer products, both cyclic VMSs (cVMS) and linear VMSs (lVMS) have been detected in human plasma. Experimental studies suggest that exposure to cVMSs may induce liver disease. Whereas, there is no human evidence of the potential health effects of VMSs yet. In this cross-sectional study, we evaluated the association of plasma VMSs concentrations with liver enzymes and Nonalcoholic fatty liver disease (NAFLD) among adults located in southwestern China. We used the fibrosis 4 calculator (FIB-4) as the NAFLD index and defined FIB-4≥1.45 as the NAFLD case. Among 372 participants, 45 (12.1%) of them were classified as NAFLD. Positive associations of plasma cVMSs concentrations with liver enzymes and NAFLD were observed among all participants. With per doubling increase in the total cVMSs, we observed a 1.40 (95%CI: 0.31, 2.48) increase in Alanine aminotransferase (ALT), a 1.56 (95%CI: 0.52, 2.61) increase in aspartate aminotransferase (AST) and a 0.04 (0.00, 0.09) increase in NAFLD index. A 19% increased risk of NAFLD was also found to be associated with per doubling increase in total cVMSs. In addition, positive associations of total lVMSs with ALT, AST and NAFLD were also detected when restricting our analyses to 230 participants living in industrial areas. Our study first provides epidemiological evidence on the association between VMSs and liver health, indicating more careful usage of VMSs may potentially reduce the burden of NAFLD, though more well-designed cohort studies are needed to confirm these findings.

Combining Crocin and Sorafenib Improves Their Tumor-Inhibiting Effects in a Rat Model of Diethylnitrosamine-Induced Cirrhotic-Hepatocellular Carcinoma. Cancers (Basel) 2023; 15:4063. [PMID: 37627094 PMCID: PMC10452334 DOI: 10.3390/cancers15164063] [Citation(s) in RCA: 17] [Impact Index Per Article: 17.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2023] [Revised: 07/28/2023] [Accepted: 07/29/2023] [Indexed: 08/27/2023] Open
Abstract
Hepatocellular carcinoma (HCC) is one of the most aggressive malignancies, with continuously increasing cases and fatalities. Diagnosis often occurs in the advanced stages, confining patients to systemic therapies such as sorafenib. Sorafenib (SB), a multi-kinase inhibitor, has not yet demonstrated sufficient efficacy against advanced HCC. There is a strong argument in favor of studying its use in combination with other medications to optimize the therapeutic results. According to our earlier work, crocin (CR), a key bioactive component of saffron, hinders HCC development and liver cancer stemness. In this study, we investigated the therapeutic use of CR or its combination with SB in a cirrhotic rat model of HCC and evaluated how effectively SB and CR inhibited tumor growth in this model. Diethylnitrosamine (DEN) was administered intraperitoneally to rats once a week for 15 weeks, leading to cirrhosis, and then 19 weeks later, leading to multifocal HCC. After 16 weeks of cancer induction, CR (200 mg/kg daily) and SB (10 mg/kg daily) were given orally to rats for three weeks, either separately or in combination. Consistently, the combination treatment considerably decreased the incidence of dyschromatic nodules, nodule multiplicity, and dysplastic nodules when compared to the HCC group of single therapies. Combined therapy also caused the highest degree of apoptosis, along with decreased proliferating and β-catenin levels in the tumor tissues. Additionally, when rats received combined therapy with CR, it showed anti-inflammatory characteristics where nuclear factor kappa B (NF-κB) and cyclooxygenase-2 (Cox-2) were considerably and additively lowered. As a result, CR potentiates the suppressive effects of SB on tumor growth and provides the opportunity to strengthen the therapeutic effects of SB in the treatment of HCC.

Fasting plasma glucose and alanine aminotransferase on the risk of hepatocellular carcinoma: A nested case-control study. Cancer Epidemiol 2023; 84:102362. [PMID: 37027905 DOI: 10.1016/j.canep.2023.102362] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2022] [Revised: 03/15/2023] [Accepted: 04/02/2023] [Indexed: 04/08/2023]
Abstract
BACKGROUND The risk of hepatocellular carcinoma (HCC) is associated with a variety of factors. However, the possible association between the abnormal metabolism of fasting plasma glucose (FPG) and alanine aminotransferase (ALT) and the risk of HCC has not been widely studied. We examined this relationship based on a prospective cohort study. METHODS 162 first-attack HCC cases during three follow-up periods (2014-2020) were selected as the case group. A control group of 648 participants was obtained by 1:4 matching of age (± 2 years) and sex with noncancer participants in the same period. Conditional logistic regression models, restricted cubic spline models, additive interaction models, and generalized additive models were used to explore the effects of FPG and ALT on the risk of HCC. RESULTS After correction for confounding factors, we found that abnormal FPG and elevated ALT increased the risk of HCC, respectively. Compared with the normal FPG group, the risk of HCC was significantly increased in the impaired fasting glucose (IFG) (OR = 1.91, 95 %CI: 1.04, 3.50) and diabetes groups (OR = 2.12, 95 %CI: 1.24, 3.63). Compared with the lowest quartile of ALT, subjects in the fourth quartile had an 84 % increased risk of HCC (OR = 1.84, 95 %CI: 1.05-3.21). Moreover, there was an interaction between FPG and ALT on the risk of HCC, and 74 % of the HCC risk could be attributed to their synergistic effect (AP = 0.74, 95 %CI: 0.56-0.92). CONCLUSION Abnormal FPG and elevated ALT are independent risk factors for HCC, and they have a synergistic effect on the risk of HCC. Therefore, serum FPG and ALT levels should be monitored to prevent the development of HCC.

Abstract
OBJECTIVE To investigate the mechanism of alanine aminotransferase 1 (ALT1) in the progression of HCC, the differentially expressed proteins (DEPs) in the ALT1 interaction network were identified by targeted proteomic analysis. METHODS Wound healing and transwell assays were conducted to assess the effect of ALT1 on cellular migration and invasion. Cell Counting Kit-8 (CCK-8), colony formation, and flow cytometry assays were performed to identify alterations in proliferation and apoptosis. After coimmunoprecipitation processing, mass spectrometry with iso-baric tags for relative and absolute quantitation was utilized to explore the protein interactions in ALT1 knockdown HepG2 cells. RESULTS The results showed that ALT1 knockdown inhibits the migration, invasion, proliferation of HepG2 cells, and promotes apoptosis. A total of 116 DEPs were identified and the bioinformatics analysis suggested that the ALT1-interacting proteins were primarily associated with cellular and metabolic processes. Knockdown of ALT1 in HepG2 cells reduced the expression of Ki67 and epithelial cell adhesion molecule (EP-CAM), while the expression of apoptosis-stimulating protein 2 of p53 (ASPP2) was increased significantly. Suppression of the ALT1 and EP-CAM expression contributed to alterations in epithelial-mesenchymal transition (EMT) -associated markers and matrix metalloproteinases (MMPs). Additionally, inhibition of ALT1 and Ki67 also decreased the expression of apoptosis and proliferation factors. Furthermore, inhibition of ALT1 and ASPP2 also changed the expression of P53, which may be the signaling pathway by which ALT regulates these biological behaviors. CONCLUSIONS This study indicated that the ALT1 protein interaction network is associated with the biological behaviors of HepG2 cells via the p53 signaling pathway.

Difference in incidence of developing hepatocellular carcinoma between hepatitis B virus-and hepatitis C virus-infected patients. World J Meta-Anal 2022; 10:186-194. [DOI: 10.13105/wjma.v10.i3.186] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/13/2022] [Revised: 06/14/2022] [Accepted: 06/27/2022] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND It is generally accepted that the incidence of hepatocellular carcinoma (HCC) in hepatitis C virus (HCV)-associated patients is higher than that in hepatitis B virus (HBV)-associated patients. The reason why this difference in the incidence of HCC occurs in patients with HBV and HCV infections remains unclear. We report the possibility that the contributing power of inflammation, which is the main risk factor for developing HCC, may be different with HBV and HCV infections.
AIM To investigate this, we surveyed the hazard ratio of inflammation for HCC development which was identified by serum alanine aminotransferase (ALT) levels between patients with HBV and HCV infections.
METHODS The PubMed database was searched (2001-2021) for studies published in English regarding the incidence of HCC identifying 8924 HBV-and 7376 HCV- infected patients. From these studies, interferon-treated patients with both HBV and HCV infections were excluded. Furthermore, in HBV patients, those administered nucleos(t)ide analogues were excluded, and in HCV patients, those administered direct acting antivirals were also excluded. Studies citing hazard ratios of HCC regarding inflammation (serum elevated alanine aminotransferase levels) were selected. Finally, there were 14 studies of HBV- infected patients and 8 studies of HCV-infected patients. We calculated the hazard ratio in patients in an inflammatory state (serum ALT levels were above the normal range).
RESULTS In the 14 studies of HBV patients, the average hazard ratio (HR) of elevated ALT for developing HCC was 2.74 [1.98-3.77] and that in the 8 studies of HCV-infected patients was 5.51 [3.08-9.83]. The HR of inflammation for HCC development in HCV-associated liver diseases is about twice that in HBV-associated liver diseases. HR in HCV-infected patients was significantly (P = 0.0391) higher than that in HBV-infected patients. In hepatitis B patients, the abnormal range adopted was 28-45 IU/L, and in hepatitis C patients, it was 20-50 IU/L. It was demonstrated that the abnormal ALT levels adopted in hepatitis B and C patients were very similar in this series.
CONCLUSION The difference in the incidence of HCC development between HBV and HCV patients may depend on the difference in the hazard risk of ALT between HBV and HCV infections.

Abstract
Hepatocellular carcinoma (HCC), one of the most common malignant tumors worldwide, is known for its grim prognosis, with untreated life expectancy being only a matter of months after the diagnosis. The difficulty in making a diagnosis early is one of the main contributing factors to the poor prognosis. Alpha-fetoprotein (AFP) had long been used as a surveillance tool, but suboptimal specificity and sensitivity has prompted liver societies to abandon the recommendation for its universal use, even in combination with ultrasonography. Most studies have shown no obvious correlation between serum AFP level and HCC tumor size, stage, or survival post-diagnosis. However, some studies concluded that a gradual rise or persistent elevation in AFP were positive predictors for tumor development. Other studies reported a fall in AFP followed by a rise in patients with HCC as well as persistently rising AFP levels without development of HCC on follow up. Our calculation of the sensitivity and specificity of persistently rising AFP for HCC were both low, at 60% and 35.8%, respectively, indicating that the presence of persistently rising AFP per se did not offer diagnostic benefit. In addition, our calculated mean slopes of persistently rising AFP levels in HCC and non-HCC patients were numerically very different, but the difference was not statistically significant. We conclude that the published data do not support a role for rising AFP levels per se in the diagnosis of HCC.

Abstract
Previous studies have shown that serum total cholesterol (TC) and serum alanine aminotransferase (ALT) are associated with liver cancer risk. However, the common contribution of TC and normal-high ALT to primary liver cancer (PLC) has not been reported. We aim to assess the separate and joint effect of low TC level and normal-high ALT level on the risk of PLC, a large prospective cohort was conducted in our study.The participants were divided into 4 groups via the cross-matching method according to TC [low level (-)/non-low level (+)] and ALT [normal level (-)/normal-high level(+)] status, and using the lower quartile value of TC and the upper quartile value of ALT as a threshold, respectively. Incident PLC was confirmed by review of medical records. Cox proportional hazards regression models and interactive additive models were used to evaluate whether the joint effect of low TC level and normal-high ALT level is associated with the risk of PLC.During 1,248,895 person-years follow-up, 298 participants were diagnosed with PLC among 114,972 subjects. In male population, TC < 4.24 mmol/L was group "TC (-)"; TC ≥ 4.24 mmol/L was group "TC (+)"; ALT < 23 U/L was group "ALT (-)": 33 U/L ≥ ALT ≥ 23 U/L was group "ALT (+)". Compared with the group "TC (+)", group "ALT (-)", respectively, the adjusted hazard ratio (HR) and 95% confidence interval (95%CI) for PLC risk was 1.74 (1.36-2.25) in group "TC (-)" and 1.49 (1.15-1.94) in group "ALT (+)". In combinatorial analysis, compared with group "TC (+) and ALT (-)", the significant increased risk of PLC were observed in group "TC (+) and ALT (+)" (HR = 1.41; 95% confidence intervals [CI]: 1.02-1.95), group "TC (-) and ALT (-)" (HR = 1.67; 95%CI: 1.24-2.27) and group "TC (-) and ALT (+)" (HR = 2.72; 95%CI: 1.81-4.09), respectively. However, no statistical significance was found among female.The separate and joint effect of low TC level and normal-high ALT level was observed for PLC risk in males. When combined, individuals with coexistence of low TC level and normal-high ALT level significantly increase the risk of PLC.

T2 mapping in gadoxetic acid-enhanced MRI: utility for predicting decompensation and death in cirrhosis. Eur Radiol 2021; 31:8376-8387. [PMID: 33782768 DOI: 10.1007/s00330-021-07805-0] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2020] [Revised: 12/21/2020] [Accepted: 02/17/2021] [Indexed: 12/24/2022]
Abstract
OBJECTIVES To determine whether T2 mapping in liver MRI can predict decompensation and death in cirrhotic patients. METHODS This retrospective study included 292 cirrhotic patients who underwent gadoxetic acid-enhanced MRI, including T1 and T2 mapping at 10-min hepatobiliary phase by using the Look-Locker and radial turbo spin-echo sequences, respectively. T1 and T2 values of the liver and spleen were measured. The association of MR parameters and serum markers with decompensation and death was investigated. Risk models combining T2Liver, serum albumin level, and Model for End-Stage Liver Disease (MELD) score were created for predicting decompensation (T2Liver, < 49.3 versus ≥ 49.3 ms) and death (< 57.4 versus ≥ 57.4 ms). RESULTS In patients with compensated cirrhosis at baseline and in the full patient cohort, 9.6% (19 of 197) and 5.1% (15 of 292) developed decompensation and died during the mean follow-up periods of 18.7 and 19.2 months, respectively. A prolonged T2Liver (hazard ratio (HR), 2.59; 95% confidence interval (CI), 1.26, 5.31) was independently predictive of decompensation along with the serum albumin level (HR, 0.28; 95% CI, 0.12, 0.68) and MELD score (HR, 1.34; 95% CI, 1.08, 1.66). T2Liver (HR, 2.61; 95% CI, 1.19, 5.72) and serum albumin level (HR, 0.46; 95% CI, 0.19, 1.14) were independent predictors of death. The mean times to decompensation (12.9 versus 29.2 months) and death (16.5 versus 29.6 months) were significantly different between the high- and low-risk groups (p < 0.001). CONCLUSION T2Liver from T2 mapping can predict decompensation and death in patients with cirrhosis. KEY POINTS • Liver T2 values from the radial turbo spin-echo (TSE) T2 mapping sequence with tiered echo sharing and pseudo golden-angle (pGA) reordering were significantly higher in decompensated cirrhosis than compensated cirrhosis. • Liver T2 values from the radial TSE T2 mapping sequence with tiered echo sharing and pGA reordering can predict decompensation and death in patients with cirrhosis. • T2 mapping is recommended as part of liver MRI examinations for cirrhotic patients because it can provide a noninvasive prognostic marker for the development of decompensation and death.

Integrated stress response in hepatitis C promotes Nrf2-related chaperone-mediated autophagy: A novel mechanism for host-microbe survival and HCC development in liver cirrhosis.

Abstract
The molecular mechanism(s) how liver damage during the chronic hepatitis C virus (HCV) infection evolve into cirrhosis and hepatocellular carcinoma (HCC) is unclear. HCV infects hepatocyte, the major cell types in the liver. During infection, large amounts of viral proteins and RNA replication intermediates accumulate in the endoplasmic reticulum (ER) of the infected hepatocyte, which creates a substantial amount of stress response. Infected hepatocyte activates a different type of stress adaptive mechanisms such as unfolded protein response (UPR), antioxidant response (AR), and the integrated stress response (ISR) to promote virus-host cell survival. The hepatic stress is also amplified by another layer of innate and inflammatory response associated with cellular sensing of virus infection through the production of interferon (IFN) and inflammatory cytokines. The interplay between various types of cellular stress signal leads to different forms of cell death such as apoptosis, necrosis, and autophagy depending on the intensity of the stress and nature of the adaptive cellular response. How do the adaptive cellular responses decode such death programs that promote host-microbe survival leading to the establishment of chronic liver disease? In this review, we discuss how the adaptive cellular response through the Nrf2 pathway that promotes virus and cell survival. Furthermore, we provide a glimpse of novel stress-induced Nrf2 mediated compensatory autophagy mechanisms in virus-cell survival that degrade tumor suppressor gene and activation of oncogenic signaling during HCV infection. Based on these facts, we hypothesize that the balance between hepatic stress, inflammation and different types of cell death determines liver disease progression outcomes. We propose that a more nuanced understanding of virus-host interactions under excessive cellular stress may provide an answer to the fundamental questions why some individuals with chronic HCV infection remain at risk of developing cirrhosis, cancer and some do not.

Abstract
OBJECTIVES We investigated the effect of daily folic acid supplementation on methotrexate (MTX) toxicity and efficacy in Japanese patients with rheumatoid arthritis (RA). METHODS We followed 19 patients treated with MTX who switched from taking weekly 5 mg folic acid supplementation (weekly regimen) to 1.25 mg daily (daily regimen). White blood cell (WBC) and platelet (PLT) counts, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) levels were collected for 24 weeks following the change. RESULTS We observed no significant changes in WBC or PLT counts. AST and ALT levels, which had exceeded the upper limits of their normal ranges at the beginning of the study, were improved significantly at weeks 4 and 8, no subsequent deterioration in liver function was found. Further, no significant changes in ESR and CRP levels were observed. CONCLUSION Our data indicate that supplementing 1.25 mg of folic acid daily rather than 5 mg weekly reduces toxicity caused by MTX without affecting its efficacy.

Abstract
BACKGROUND & AIMS The association of serum liver enzyme levels with all-cause mortality in individuals without hepatitis B virus or hepatitis C virus infection is inconsistent. We aimed to investigate all-cause and non-liver disease mortality according to levels of serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), and gamma-glutamyltransferase (GGT) stratified by hepatitis virus infection status in a Japanese cohort. METHODS Participants were 7243 men and 13 513 women aged 40-69 years at the baseline survey in 1993-1994. Multivariate-adjusted hazard ratios of death from the baseline health check-up to December 2012 were calculated with a Cox proportional hazards model controlling for potential confounding factors. RESULTS During follow-up, 2235 deaths in men and 1901 deaths in women were identified. All serum liver enzymes were associated with all-cause mortality in each sex and hepatitis virus infection status. In participants without infection, those with more than twice the upper level of normal (ULN), which was defined as 30 IU/L for AST and ALT and 50 IU/L for GGT, had a higher risk of non-liver disease mortality compared to those below the ULN (HR 1.69; 95% confidence interval 1.13-2.53, 1.49; 1.02-2.18, 1.39; 1.11-1.73, 1.72; 1.08-2.74 and 1.72; 1.10-2.69 for AST, ALT, and GGT in men and AST and GGT in women, respectively), except for ALT in women. CONCLUSIONS In participants without hepatitis virus infection, serum liver enzyme levels were positively associated with all-cause mortality. Similar associations were also found for non-liver disease mortality.

Abstract
Individuals infected with hepatitis C virus (HCV) are at high risk of developing progressive liver disease, including cirrhosis and hepatocellular carcinoma (HCC). How HCV infection causes liver destruction has been of significant interest for many years, and apoptosis has been proposed as one operative mechanism. In this study, we employed a tissue culture-adapted strain of HCV (JFH1T) to test effects of HCV infection on induction of programmed cell death (PCD) in Huh-7.5 cells. We found that HCV infection reduced the proliferation rate and induced caspase-3-mediated apoptosis in the infected cell population. However, in addition to apoptosis, we also observed infected cells undergoing caspase-1-mediated pyroptosis, which was induced by NLRP3 inflammasome activation. By co-culturing HCV-infected Huh-7.5 cells with an HCV-non-permissive cell line, we also demonstrated induction of both apoptosis and pyroptosis in uninfected cells. Bystander apoptosis, but not bystander pyroptosis, required cell-cell contact between infected and bystander cells. In summary, these findings provide new information on mechanisms of cell death in response to HCV infection. The observation that both apoptosis and pyroptosis can be induced in bystander cells extends our understanding of HCV-induced pathogenesis in the liver.

Abstract
Overnutrition can promote liver cancer in mice and humans that have liver damage caused by alcohol, viruses, or carcinogens. However, the mechanism linking diet to increased liver tumorigenesis remains unclear in the context of whether tumorigenesis is secondary to obesity, or whether nutrients like sugar or fat drive tumorigenesis independent of obesity. In male mice, liver tumor burden was recently found to correlate with sugar intake, independent of dietary fat intake and obesity. However, females are less susceptible to developing liver cancer than males, and it remains unclear how nutrition affects tumorigenesis in females. Herein, female mice were exposed to the liver carcinogen diethylnitrosamine (DEN) and fed diets with well-defined sugar and fat content. Mice fed diets with high sugar content had the greatest liver tumor incidence while dietary fat intake was not associated with tumorigenesis. Diet-induced postprandial hyperglycemia and fasting hyperinsulinemia significantly correlated with tumor incidence, while tumor incidence was not associated with obesity and obesity-related disorders including liver steatosis, glucose intolerance, or elevated serum levels of estrogen, ALT, and lipids. These results simplify the pathophysiology of diet-induced liver tumorigenesis by focusing attention on the role of sugar metabolism and reducing emphasis on the complex milieu associated with obesity.

Abstract
BACKGROUND & AIMS In patients with cirrhosis, the risk of hepatocellular carcinoma (HCC) depends upon age, gender and the etiology of liver disease. Few studies are available in Caucasian patients with alcoholic or metabolic cirrhosis without viral hepatitis. METHODS Cross-sectional clinical data from 905 HCV- and HBV-negative Caucasian patients with alcoholic or metabolic cirrhosis were prospectively collected in four French centres. The risk factors for HCC were identified by logistic regression analysis in the whole population and in a nested case-control study. RESULTS The etiology of cirrhosis was alcoholic (48%), metabolic (7%) or mixed (45%). Patients were predominantly male (80%), mean age 62 years old and 31% had HCC. Mean body mass index (BMI) was 27 ± 5 and 30% were obese at inclusion. The maximum BMI reached throughout life was 31 ± 6 and 63% had been obese. Ninety percent of the population had daily alcohol consumption, 73% were smokers. Hepatocellular carcinoma was independently related to male gender (P < 0.0001), older age (P < 0.0001), past obesity (P = 0.007), diabetes (P = 0.037), abnormal levels of transaminases (P < 0.0001) and tobacco consumption (P = 0.007). The case-control study (200 HCC cases matched with 400 non-HCC cases for gender, age and Child-Pugh score) confirmed past obesity, tobacco and abnormal levels of transaminases. CONCLUSIONS Beside diabetes, male gender and age, a past history of obesity, but not an existing overweight, as well as exposure to tobacco and elevated transaminases were three risk factors which could improve the strategy for HCC screening in Caucasian cirrhotic patients without hepatitis B or C.

Abstract
OBJECTIVES In short-term observations, interferon (IFN) therapy has been shown to be effective in producing both biochemical and virological responses in children with chronic hepatitis B virus (HBV) infection. However, in long-term follow up, no studies have shown a clear advantage of IFN therapy during childhood. We conducted a retrospective study on the sustained effect of IFN therapy among a Japanese pediatric population. METHODS AND SUBJECTS A retrospective study was performed on 155 children with chronic HBV infection who were followed in two affiliated hospitals during the period from 1986 to 2013. RESULTS The 155 patients comprised 97 males and 58 female. Infection route was maternal transmission in 96/155 patients. HBV genotype was A in 17, B in 6, and C in 51 patients. IFN therapy was performed in 48 patients. One year after the completion of IFN therapy, normalization of alanine aminotransferase (ALT) and lower viral levels (<10(4) copies/ml) was observed in 43 and 29 patients, respectively. The sustained effects of IFN therapy were evaluated by comparison between 43 hepatitis B e-antigen (HBeAg)-positive patients treated with IFN and 67 patients with chronic hepatitis B observed without IFN therapy. A Cox's proportional hazard analysis showed a higher seroconversion rate in the IFN group than in the untreated group (p = 0.003). Similarly, there were higher rates of ALT normalization and lower viral levels in the IFN group than in the untreated group (p = 0.001 for both). CONCLUSION IFN therapy showed sustained effects for achieving ALT normalization and HBeAg seroconversion and for reducing the viral load in children with chronic hepatitis B.

Abstract
BACKGROUND Evidence suggests that estrogen plays a preventive role in primary liver cancer development, and it might be thought that isoflavones, which are structurally similar to estrogens and bind to estrogen receptors, are associated with the risk of liver cancer. We investigated this suspected association by measuring plasma concentrations of isoflavones in a nested case-control study of a population-based prospective cohort in Japan. METHODS From 18,628 target participants ages 40 to 69 years who returned the baseline questionnaire and provided blood samples, we selected those with either hepatitis B or hepatitis C virus infection at baseline (n = 1,544). Among these, 90 (28 women and 62 men) were newly diagnosed with primary liver cancer from 1993 through 2006; they were matched with 175 controls (54 women and 121 men). Plasma concentrations of isoflavones (genistein, daidzein, glycitein, and equol) were measured using triple quadrupole tandem liquid chromatography-mass spectrometry. The ORs of liver cancer development based on plasma concentrations were estimated with a conditional logistic regression model. RESULTS Basically, distributions of plasma isoflavone concentrations did not differ between the cases and controls. No statistically significant associations of genistein, daidzein, glycitein, and equol with primary liver cancer risk were found in either women or men. CONCLUSIONS In middle-aged Japanese women and men with hepatitis virus infection, plasma isoflavones were unassociated with the occurrence of primary liver cancer. IMPACT The role of isoflavones in liver carcinogenesis merits further study using both biomarkers and data on dietary intake of isoflavones.

Abstract
Hepatocellular carcinoma (HCC) is the third leading fatal cancer worldwide and its incidence continues to increase. Chronic viral hepatitis involving either hepatitis B virus (HBV) or hepatitis C virus (HCV) infection is the leading etiology for HCC, making HCC prevention a major goal of antiviral therapy. While recent clinical observations and translational research have enhanced our understanding of the molecular mechanisms driving the initiation and progression of HCC, much remains unknown. Current data indicates that HCC tumors are highly complex and heterogeneous resulting from the aberrant function of multiple molecular pathways. This complex biology is responsible, at least in part, for the absence of highly efficient target-directed therapies for this deadly cancer. Additionally, the direct or indirect effect of HBV and HCV infection on the development of HCC is still a contentious issue. Thus, the question remains whether viral hepatitis-associated HCC stems from virus-specific factors, and/or from a general mechanism involving inflammation and tissue regeneration. In this review we summarize general mechanisms implicated in HCC, emphasizing data generated by new technologies available today. We also highlight specific pathways by which HBV and HCV could be involved in HCC pathogenesis. However, improvements to current in vitro and in vivo systems for both viruses will be needed to rigorously define the temporal sequence and specific pathway dysregulations that drive the strong clinical link between chronic hepatitis virus infection and HCC.

Abstract
Chronic oxidative stress plays a key role in the progression of nonalcoholic steatohepatitis (NASH). We examined the efficacy of antioxidative electron treatment on type 2 diabetes-induced NASH in a rat model. We established NASH model rats, induced by neonatal administration of streptozotocin and a high-fat diet, which exhibited pathologically high values of alanine aminotransferase (ALT), glucose, and malondialdehyde (MDA). The rats were exposed to electron discharge at very low energy for 4 weeks; this dose results in the reduction of Fe(3+) and glutathione disulfide in vitro. Serum ALT values were increased from baseline (8 weeks) to 125.0 ± 13 U/L at 10 weeks in the control group. In contrast, the values in the treated group did not show any increase at 10 weeks [87 ± 10 U/L (p = 0.0391)]. Hepatic MDA levels were also significantly decreased at 12 weeks (p < 0.05), but 8-hydroxy-2'-deoxyguanosine values were not statistically significant (p = 0.076). A gradual but steadily decreasing trend from initially high glucose levels was observed, though the values were not significant in 12-week-old animals (p = 0.074). However, the serum values of MDA, ALT, and glucose were well correlated. The progression of fibrosis as measured by increased serum levels of hyaluronic acid and histological examinations were not affected by the treatment in this model. Antioxidative electron treatment at very low energy attenuated the pathogenically elevated liver inflammation and oxidative stress, together with presumably impaired glucose metabolism in NASH rat model.

Abstract
BACKGROUND Excess body weight is an independent risk factor for primary liver cancer, and the role of adiponectin in the pathogenesis of obesity-related malignancies is a focus of research interest. Few prospective studies have examined the association between circulating adiponectin and liver cancer risk, so we investigated this association in a nested case-control study of a population-based prospective cohort in Japan. METHODS From 18,628 target participants of ages 40 to 69 years who returned the baseline questionnaire and provided blood samples, we selected those with either hepatitis B or C virus infection at baseline (n = 1,544). Among these, 90 were newly diagnosed with primary liver cancer from 1993 through 2006, and matched to 177 controls. The ORs of liver cancer development based on plasma levels of adiponectin were estimated with a conditional logistic regression model. RESULTS Median values of total and high-molecular-weight (HMW) adiponectin tended to be higher in the patients with liver cancer, and plasma levels of adiponectin were positively associated with liver cancer risk. Body mass index- and diabetes-adjusted ORs for the highest tertile of total and HMW adiponectin levels versus the lowest were 3.30 [95% confidence interval (CI), 1.45-7.53; Ptrend < 0.01] and 3.41 (95% CI, 1.50-7.73; Ptrend < 0.01), respectively. There was no effect modification by body mass index and diabetes. CONCLUSIONS Higher plasma adiponectin levels were associated with an increased risk of primary liver cancer in middle-aged Japanese adults with hepatitis virus infection. IMPACT Circulating adiponectin levels may be a risk marker for primary liver cancer.

Abstract
AIMS 11β-Hydroxysteroid dehydrogenase type 1 (HSD11B1), which converts inactive glucocorticoid to active glucocorticoid, plays a critical role in pathogenesis of non-alcoholic fatty liver disease (NAFLD). Serum alanine aminotransferase (ALT), an indicator of hepatocellular injury, has been suggested as a surrogate marker for NAFLD. To date, no study has specifically examined the relationship between HSD11B1 gene polymorphisms and ALT. METHODS A study was conducted to examine the association of common single nucleotide polymorphisms (SNPs) in HSD11B1 (rs12086634, rs1000283) with serum ALT level in 756 Korean subjects (348 males and 408 females). ALT values were divided into two groups: elevated (>33U/l in males, >25U/l in females) and normal. RESULTS SNPs showed a significant association with elevated ALT. According to results of logistic regression analysis adjusted for confounding variables, the GT+GG genotype for rs12086634 and the GA+AA genotype for rs1000283 showed significantly higher frequencies of elevated ALT, compared with the TT and GG genotypes, respectively (GT/GG vs. TT; OR 1.685, 95% CI 1.175-2.416, P=0.005, GA/AA vs. GG; OR 2.057, 95% CI 1.401-3.020, P<0.001, respectively). CONCLUSIONS HSD11B1 polymorphisms (rs12086634 and rs1000283) are associated with elevated levels of ALT. Findings from this study suggest a possible association between HSD11B1 polymorphisms and hepatocellular injury, such as that seen in patients with NAFLD.

Abstract
BACKGROUND The single nucleotide polymorphism (SNP) rs738409 in patatin-like phospholipase domain-containing protein 3 (PNPLA3) is associated with hepatic fat accumulation and disease progression in patients with non-alcoholic fatty liver disease and alcoholic liver disease (ALD). This study was conducted to determine whether PNPLA3 rs738409 SNPs affect development and prognosis of hepatocellular carcinoma (HCC) in patients with various liver diseases. METHODS We enrolled 638 consecutive Japanese patients newly diagnosed with HCC between 2001 and 2010: 72 patients with hepatitis B virus (HBV), 462 with hepatitis C virus (HCV), and 104 with non-B non-C (NBNC). RESULTS NBNC patients exhibited large tumors of advanced TNM stages at HCC diagnosis, and had significantly poorer prognosis than HBV or HCV patients (P < 0.001 and <0.001, respectively; log-rank test). The G/G genotype of PNPLA3 rs738409 SNP had significantly higher distribution in NBNC patients (P < 0.001) and was significantly associated with higher body mass index (BMI) and an increased aspartate aminotransferase to platelet ratio index. No significant differences were observed in survival with differences in PNPLA3 SNP genotypes among the patients, although ALD patients with the G/G genotype of PNPLA3 SNP and low BMI had significantly poorer survival than those with high BMI (P = 0.028). CONCLUSIONS The G/G genotype of PNPLA3 rs738409 SNP was more frequently distributed, and associated with BMI and fibrosis among NBNC-HCC patients but not among HBV or HCV patients. These genotypes might affect HCC prognosis in ALD patients, but not in HBV, HCV, or NAFLD patients.

Abstract
Objective Hepatitis B virus (HBV) infection remains a significant public health problem. The purpose of this study was to investigate the seroepidemiology of HBV in people living in the insular regions, and to provide the most recent baseline data for planning and monitoring of health. Methods A cross-sectional, community-based survey was conducted without age restriction, on two isolated islands, Zhoushan and Yuhuan, China. The study sample was selected by random multistage cluster sampling. Serological samples and demographic information were collected from 15878 participants. Results The prevalences of anti-HBV core antibody (anti-HBc), hepatitis B virus surface antigen (HBsAg), and anti-HBV surface antibody (anti-HBs) were 33.1, 10.4, and 56.1%, respectively. We found statistically significant differences of HBV markers in men versus women (P<0.01). The prevalence of HBV infection increased with age. There were significant differences in the rates of HBsAg and anti-HBc positivity between the two islands (P<0.01). Alanine aminotransferase (ALT) levels were elevated (>38 IU/L) in 15.6% and 7.2% of the HBsAg-positive and negative groups, respectively. Elevated ALT levels were significantly higher in males (12.0%) compared with females (5.8%) (P<0.01). The α-fetoprotein (AFP) positivity rate was 0.6% in HBsAg-positive participants over the age of 30. Conclusion Due to the geographic location, we found that the HBV prevalence and potential for the development of hepatocellular carcinoma remained high in insular regions of southeast China, and are far above the national figures. Although a vaccination program has been in effect over the last 20 years, several additional measures should be adopted by the government to limit the spread of hepatitis B. These include the management of high risk persons and the floating population living on the islands, expansion of the immune population, and increased health education for fisherman.

Abstract
UNLABELLED The guideline on the management of chronic hepatitis B (CHB) was first developed in 2004 and revised in 2007 by the Korean Association for the Study of the Liver (KASL). Since then there have been many developments, including the introduction of new antiviral agents and the publications of many novel research results from both Korea and other countries. In particular, a large amount of knowledge on antiviral resistance--which is a serious issue in Korea--has accumulated, which has led to new strategies being suggested. This prompted the new guideline discussed herein to be developed based on recent evidence and expert opinion. TARGET POPULATION The main targets of this guideline comprise patients who are newly diagnosed with CHB and those who are followed or treated for known CHB. This guideline is also intended to provide guidance for the management of patients under the following special circumstances: malignancy, transplantation, dialysis, coinfection with other viruses, pregnancy, and children.

Abstract
OBJECTIVE Hepatitis B is a major public health problem in China. However, in the past 10 years, estimates of the prevalence of hepatitis B virus (HBV) have been sparse, with results that do not always agree. The purpose of this study was to investigate the epidemiology of HBV in adults and to provide the most recent baseline data for planning and monitoring of health. METHODS The prevalence of HBV was determined in a community-based, cross-sectional, age-stratified sample of adults (aged 20 years or older). The study population was selected using random multistage cluster sampling. Demographic information and serological samples were obtained from 19 933 participants. RESULTS The prevalence of anti-HBV core antibody, HBV surface antigen (HBsAg), and anti-HBV surface antibody was 38.6, 7.9, and 44.9%, respectively. We found statistically significant differences in hepatitis B infection between men and women (P<0.001). The prevalence of HBV infection increased with age. The rates of HBsAg positivity and HBV infection in individuals living on an island were higher than those of individuals living in plains. The alanine aminotransferase level was elevated (≥38 IU/l) in 15.7 and 7.2% of HBsAg-positive and HBsAg-negative patients; the proportion of elevated alanine aminotransferase was markedly higher in men (12.7%) than in women (4.7%) (P<0.001). The α-fetoprotein-positive rate was 2% in HBsAg-positive individuals who were aged 30 years or older. CONCLUSION Borderline intermediate/high endemicity was found among adults in the northern region of Zhejiang Province. The vaccination program has contributed to a reduction in infection over the last 20 years, although further efforts are required to turn the region into a 'low-endemicity' area.

Abstract
BACKGROUND Liver stiffness assessed using transient elastography is described as a potential risk factor for hepatocellular carcinoma (HCC) in cirrhosis. However, the strict assessment of hepatic parenchymal areas uninvolved with HCC has not been investigated. AIM To determine if liver stiffness of nonmalignant hepatic parenchyma using magnetic resonance elastography (MRE) is higher in patients with HCC compared with controls. METHODS Cases were defined by compensated cirrhosis with a Child-Turcotte-Pugh score <7 and HCC by radiological criteria or histology. Control subjects with compensated cirrhosis were frequency matched with cases by gender and disease aetiology. Overt manifestations of portal hypertension and previous therapy for liver disease or HCC were exclusion criteria. Region of interest analyses were performed on hepatic parenchyma regions distant to HCC location among cases. RESULTS Thirty patients with HCC and 60 matched controls comprised the study cohort. The mean age for cases was 64±10 years (range, 45-85) with 70% being men. Major disease aetiologies were chronic viral hepatitis (57%), non-alcoholic fatty liver disease (33%) and alcohol (10%). Twenty-eight (93%) patients had solitary HCC lesions with a mean size of 5.2 cm (range, 2-14 cm). However, patients with HCC had similar liver stiffness among uninvolved areas distant to HCC lesions, when compared with controls without HCC (mean, 6.1±2.0 vs. 6.3±2.5 kPa, P=0.7). CONCLUSION In contrast to previous studies with transient elastography, we did not observe a systematic association between liver stiffness assessed using MRE and the presence of HCC in patients with compensated cirrhosis.

Abstract
AIM To identify factors associated with the age at onset of hepatitis C virus (HCV)-related hepatocellular carcinoma (HCC). METHODS Five hundred and fifty-six consecutive patients positive for HCV antibody and treatment-naïve HCC diagnosed between 1995 and 2004 were analyzed. Patients were classified into three groups according to age at HCC onset: < 60 years (n = 79), 60-79 years (n = 439), or ≥ 80 years (n = 38). Differences among groups in terms of sex, body mass index (BMI), lifestyle characteristics, and liver function were assessed. Factors associated with HCC onset in patients < 60 or ≥ 80 years were analyzed by logistic regression analysis. RESULTS Significant differences emerged for sex, BMI, degree of smoking and alcohol consumption, mean bilirubin, alanine aminotransferase (ALT), and γ-glutamyl transpeptidase (GGT) levels, prothrombin activity, and platelet counts. The mean BMI values of male patients > 60 years old were lower and mean BMI values of female patients < 60 years old were higher than those of the general Japanese population. BMI > 25 kg/m² [hazard ratio (HR), 1.8, P = 0.045], excessive alcohol consumption (HR, 2.5, P = 0.024), male sex (HR, 3.6, P = 0.002), and GGT levels > 50 IU/L (HR, 2.4, P = 0.014) were independently associated with HCC onset in patients < 60 years. Low ALT level was the only factor associated with HCC onset in patients aged ≥ 80 years. CONCLUSION Increased BMI is associated with increased risk for early HCC development in HCV-infected patients. Achieving recommended BMI and reducing alcohol intake could help prevent hepatic carcinogenesis.

Abstract
Recently, much progress has been made in the field of hepatitis B, such as natural history of the disease in relation to the amount of hepatitis B virus (HBV) DNA, genotypes of HBV influencing the natural course and treatment effects, mutations of HBV influencing the severity of the disease and development of hepatocellular carcinoma, and antiviral treatment such as nucleos(t)ide analogues and pegylated interferon. To make the consensus for the diagnosis, management and treatment of hepatitis B, a meeting was held during 45th annual meeting of Japan Society of Hepatology (JSH) in June 2009. In the meeting, recommendations and informative statements were discussed on the following subjects: (i) natural history of HBV infection; (ii) clinical implication of HBV genotypes; (iii) HBV mutations and their potential impact on pathogenesis of HBV infection; (iv) indications for antiviral treatment of chronic hepatitis B; (v) nucleos(t)ide analogues for chronic hepatitis B; and (vi) interferon therapy for chronic hepatitis B. The presenters reviewed the data on these subjects and proposed the consensus statements and recommendations. These statements were discussed among the organizers and presenters, and were approved by the participants of the meeting. In the current report, the relevant data were reviewed and the 12 consensus statements and nine recommendations on chronic hepatitis B were described.

Abstract
AIM This study was conducted to evaluate the efficacy and safety of radiofrequency ablation (RFA) therapy in elderly patients with hepatocellular carcinoma (HCC). METHODS Four hundred and sixty-one patients with naïve HCC, including 107 elderly (aged ≥75 years) patients, who were treated with RFA between 2000 and 2007, were enrolled. Baseline characteristics, survival/recurrence rates and complications after RFA were compared between elderly and non-elderly patients. RESULTS In the elderly group, the proportion of men, alcohol consumption, serum alanine aminotransferase and γ-glutamyl transpeptidase levels were significantly lower compared with those in the non-elderly group. There were no differences in Child-Pugh grade and tumor characteristics between the two groups. The cumulative survival rates in the elderly group were 82% at 3 years and 61% at 5 years, which was equivalent to the non-elderly group. Similarly, no differences were observed in recurrence rates. In multivariate analysis, Child-Pugh grade and tumor-related factors were significant factors associated with survival, but age was not. Although elderly patients had more extrahepatic comorbidities, their presence was not a factor associated with survival prognosis or complication after RFA. CONCLUSION RFA treatment might be safe and effective in elderly patients, as well as non-elderly patients, with HCC.

Abstract
Abstract Objective. To assess retrospectively whether continuously high serum alanine aminotransferase (ALAT) levels (<80 IU) in the first three successive years after the diagnosis of liver cirrhosis (LC) are predictive of a subsequent high incidence of hepatocellular carcinoma (HCC) in patients with Child Stage A hepatitis C virus (HCV)-LC. Material and methods. The study comprised 132 HCV-LC (Child Stage A) patients who had not received interferon therapy but had been treated with anti-inflammatory agents. At the end of a 3-year follow-up after the diagnosis of LC, the patients were subdivided into three groups according to their serum ALAT levels and the subsequent incidence of HCC was assessed. Results. The cumulative incidence of HCC starting from 3 years after the diagnosis of LC in the continuously high ALAT group (annual average over 3 years always > or =80 IU; n=41; Group A) was markedly higher than that in the continuously low ALAT group (always <80 IU; n=48; Group B) (p<0.005) during an observation period of 7.9+/-3.7 years. The incidence of HCC in Group A was 11.8%/year. The odds ratios of developing HCC in Group A and Group C (mixed high and low ALAT levels; n=43) were 5.1-fold and 1.5-fold that of Group B, respectively. A multivariate analysis revealed that the ALAT group was independently associated with HCC development. Conclusions. Continuously high ALAT levels for three successive years following the diagnosis of LC can be predictive of a very high incidence of HCC in Child A HCV-LC patients. Prospective trials using therapeutic approaches aimed at decreasing ALAT levels are necessary in order to confirm a positive impact of ALAT reduction on the incidence of HCC in patients with HCV-LC.
