World J Gastroenterol 2024; 30:1480-1487. [PMID: 38617460 PMCID: PMC11008415 DOI: 10.3748/wjg.v30.i11.1480] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/29/2023] [Revised: 01/30/2024] [Accepted: 03/04/2024] [Indexed: 03/21/2024] Open
Abstract
During the outbreak of the coronavirus disease 2019 (COVID-19) pandemic, particular interest rose regarding the interaction between metabolic dysfunction-associated fatty liver disease (MAFLD) and the COVID-19 infection. Several studies highlighted the fact that individuals with MAFLD had higher probability of severe acute respiratory syndrome coronavirus 2 infection and more severe adverse clinical outcomes. One of the proposed mechanisms is the inflammatory response pathway, especially the one involving cytokines, such as interleukin 6, which appeared particularly elevated in those patients and was deemed responsible for additional insult to the already damaged liver. This should increase our vigilance in terms of early detection, close follow up and early treatment for individuals with MAFLD and COVID-19 infection. In the direction of early diagnosis, biomarkers such as cytokeratin-18 and scoring systems such as Fibrosis-4 index score are proposed. COVID-19 is a newly described entity, expected to be of concern for the years to come, and MAFLD is a condition with an ever-increasing impact. Delineating the interaction between these two entities should be brought into the focus of research. Reducing morbidity and mortality of patients with COVID-19 and MAFLD should be the ultimate objective, and the optimal way to achieve this is by designing evidence-based prevention and treatment policies.

The utility of non-invasive tests to assess advanced fibrosis in Asian subjects with chronic hepatitis B and concomitant hepatic steatosis. Liver Int 2023; 43:1008-1014. [PMID: 36855842 DOI: 10.1111/liv.15541] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/20/2022] [Revised: 01/11/2023] [Accepted: 02/07/2023] [Indexed: 03/02/2023]
Abstract
BACKGROUND Chronic hepatitis B (CHB) is endemic to Asia and is a leading cause of liver-related morbidity. The prevalence of concomitant CHB and hepatic steatosis (HS) is increasing in Asia. Non-invasive tests (NITs) including FIB-4, NFS and APRI assess fibrosis in populations with a single aetiology, but not in subjects with concomitant CHB and HS. AIM To explore the accuracy of NITs in predicting advanced fibrosis in patients with concomitant CHB and HS. METHODOLOGY This multicentre study of CHB patients who underwent liver biopsy explored clinical characteristics of these subjects, stratified by presence of HS. Fibrosis scores from NITs were compared against histological fibrosis stage in CHB subjects with and without HS. RESULTS 2262 subjects were enrolled, 74.5% were males, and the mean age was 39.5 years ±11.8 SD. 984 (44.4%) had HS, 824 (36.4%) had advanced fibrosis. In the CHB group, the AUROC for advanced fibrosis were 0.65 (95% CI 0.62-0.69) for FIB-4 and 0.63 (95% CI 0.60-0.66) for APRI. The specificities were 0.94 for FIB-4 greater than 3.25 and 0.81 for APRI greater than 1.5. In the CHBHS group, the AUROC for advanced fibrosis were 0.67 (95% CI 0.63-0.71) for FIB-4, 0.60 (95% CI 0.56-0.64) for APRI and 0.65 (95% CI 0.61-0.69) for NFS. The specificities were 0.95 for FIB-4 greater than 3.25, 0.88 for APRI greater than 1.5 and 0.99 for NFS greater than 0.675. CONCLUSION The performance of NITs to exclude advanced fibrosis did not differ greatly regardless of HS. FIB-4 and NFS have the best negative predictive values of 0.80 and 0.78, respectively, to exclude advanced fibrosis in CHBHS subjects.

Abstract
Nonalcoholic fatty liver disease, characterized by excessive accumulation of fat in the liver, is the most common chronic liver disease worldwide. The current standard for the detection of hepatic steatosis is liver biopsy; however, it is limited by invasiveness and sampling errors. Accordingly, MR spectroscopy and proton density fat fraction obtained with MRI have been accepted as non-invasive modalities for quantifying hepatic steatosis. Recently, various quantitative ultrasonography techniques have been developed and validated for the quantification of hepatic steatosis. These techniques measure various acoustic parameters, including attenuation coefficient, backscatter coefficient and speckle statistics, speed of sound, and shear wave elastography metrics. In this article, we introduce several representative quantitative ultrasonography techniques and their diagnostic value for the detection of hepatic steatosis.

Abstract
The gastrointestinal tract is the body's largest interface between the host and the external environment. People infected with SARS-CoV-2 are at higher risk of microbiome alterations and severe diseases. Recent evidence has suggested that the pathophysiological and molecular mechanisms associated with gastrointestinal complicity in SARS-CoV-2 infection could be explained by the role of angiotensin-converting enzyme-2 (ACE2) cell receptors. These receptors are overexpressed in the gut lining, leading to a high intestinal permeability to foreign pathogens. It is believed that SARS-CoV-2 has a lesser likelihood of causing liver infection because of the diminished expression of ACE2 in liver cells. Interestingly, an interconnection between the lungs, brain, and gastrointestinal tract during severe COVID-19 has been mentioned. We hope that this review on the molecular mechanisms related to the gastrointestinal disorders as well as neurological and hepatic manifestations experienced by COVID-19 patients will help scientists to find a convenient solution for this and other pandemic events.

Abstract
Hepatitis C virus (HCV) infection is a systemic disease that is implicated in multiple extrahepatic organ dysfunction contributing to its protean manifestations. HCV is associated with diverse extrahepatic disorders including atherosclerosis, glucose and lipid metabolic disturbances, alterations in the iron metabolic pathways, and lymphoproliferative diseases over and above the traditional liver manifestations of cirrhosis and hepatocellular carcinoma. The orchestration between HCV major proteins and the liver-muscle-adipose axis, poses a major burden on the global health of human body organs, if not adequately addressed. The close and inseparable associations between chronic HCV infection, metabolic disease, and cardiovascular disorders are specifically important considering the increasing prevalence of obesity and metabolic syndrome, and their economic burden to patients, the healthcare systems, and society. Cellular and molecular mechanisms governing the interplay of these organs and tissues in health and disease are therefore of significant interest. The coexistence of metabolic disorders and chronic hepatitis C infection also enhances the progression to liver fibrosis and hepatocellular carcinoma. The presence of metabolic disorders is believed to influence the chronicity and virulence of HCV leading to liver disease progression. This comprehensive review highlights current knowledge on the metabolic manifestations of hepatitis C and the potential pathways in which these metabolic changes can influence the natural history of the disease.

SARS-CoV-2 infection of the liver directly contributes to hepatic impairment in patients with COVID-19. J Hepatol 2020; 73:807-816. [PMID: 32437830 PMCID: PMC7211738 DOI: 10.1016/j.jhep.2020.05.002] [Citation(s) in RCA: 416] [Impact Index Per Article: 104.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/13/2020] [Revised: 04/27/2020] [Accepted: 05/03/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS Liver enzyme abnormalities are common in patients with coronavirus disease 2019 (COVID-19). Whether or not severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection can lead to liver damage per se remains unknown. Herein, we reported the clinical characteristics and liver pathological manifestations of COVID-19 patients with liver enzyme abnormalities. METHODS We analyzed 156 patients diagnosed with COVID-19 from 2 designated centers in China and compared clinical features between patients with or without elevated aminotransferases. Postmortem liver biopsies were obtained from 2 cases who had elevated aminotransferases. We investigated the patterns of liver impairment by electron microscopy, immunohistochemistry, TUNEL assay and pathological studies. RESULTS Sixty-four out of 156 (41.0%) patients with COVID-19 had elevated aminotransferases. The median levels of alanine aminotransferase were 50 U/L vs. 19 U/L, respectively, aspartate aminotransferase were 45.5 U/L vs. 24 U/L, respectively in abnormal and normal aminotransferase groups. Liver enzyme abnormalities were associated with disease severity, as well as a series of laboratory tests including higher alveolar-arterial oxygen partial pressure difference, higher gamma-glutamyltransferase, lower albumin, decreased CD4+ T cells and B lymphocytes. Ultrastructural examination identified typical coronavirus particles, characterized by spike structures, in the cytoplasm of hepatocytes in 2 COVID-19 cases. SARS-CoV-2-infected hepatocytes displayed conspicuous mitochondrial swelling, endoplasmic reticulum dilatation and glycogen granule decrease. Histologically, massive hepatic apoptosis and some binuclear hepatocytes were observed. Taken together, both ultrastructural and histological evidence indicated a typical lesion of viral infection. Immunohistochemical results showed scarce CD4+ and CD8+ lymphocytes. No obvious eosinophil infiltration, cholestasis, fibrin deposition, granuloma, massive central necrosis, or interface hepatitis were observed. CONCLUSIONS SARS-CoV-2 infection in the liver directly contributes to hepatic impairment in patients with COVID-19. Hence, a surveillance of viral clearance in liver and long-term outcome of COVID-19 is required. LAY SUMMARY Liver enzyme abnormalities are common in patients with coronavirus disease 2019 (COVID-19). We reported the clinical characteristics and liver pathological manifestations of COVID-19 patients with elevated liver enzymes. Our findings suggested that SARS-CoV-2 infection of the liver is a crucial factor contributing to hepatic impairment in patients with COVID-19.

Abstract
BACKGROUND AND AIMS Hepatitis virus and alcohol are the main factors leading to liver damage. Synergy between hepatitis B virus (HBV) and alcohol in promoting liver cell damage and disease progression has been reported. However, the interaction of HBV and ethanol in hepatic steatosis development has not been fully elucidated. METHODS Eight-week-old male C57BL/6 mice were treated with or without HBV, ethanol, or the combination of HBV and ethanol (HBV+EtOH), followed by a three-week high-fat diet (HFD) regimen. Liver histology, serum biomarkers, and liver triglyceride levels were analysed. Furthermore, a meta-analysis of the effects of alcohol and HBV on hepatic steatosis in populations was performed. RESULTS Hepatic steatosis was significantly more severe in the HBV+EtOH group than in the other groups. The serum alanine aminotransferase, aspartate aminotransferase and liver triglyceride levels in the HBV+EtOH group were also significantly higher than those in the other groups. The HBeAg and HBsAg levels in the HBV+EtOH group were significantly higher than those in the pair-fed HBV-infected mice. In addition, the meta-analysis showed that alcohol consumption increased the risk of hepatic steatosis by 43% in HBV-infected patients (pooled risk ratio (RR)=1.43, P<0.01). CONCLUSIONS Alcohol and HBV synergistically promote high-fat diet-induced hepatic steatosis in mice. In addition, alcohol consumption increases the risk of hepatic steatosis in HBV-infected patients.

Abstract
Recent evidence has demonstrated a strong interplay and multifaceted relationship between non-alcoholic fatty liver disease (NAFLD) and cardiovascular disease (CVD). CVD is the major cause of death in patients with NAFLD. NAFLD also has strong associations with diabetes and metabolic syndrome. In this comprehensive review, we aimed to overview the primary environmental and genetic risk factors of NAFLD, and CVD and also focus on the genetic aspects of these two disorders. NAFLD and CVD are both heterogeneous diseases with common genetic and molecular pathways. We have searched for the latest published articles regarding this matter and tried to provide an overview of recent insights into the genetic aspects of NAFLD and CVD. The common genetic and molecular pathways involved in NAFLD and CVD are insulin resistance (IR), subclinical inflammation, oxidative stress, and atherogenic dyslipidemia. According to an investigation, the exact associations between genomic characteristics of NAFLD and CVD and casual relationships are not fully determined. Different gene polymorphisms have been identified as the genetic components of the NAFLDCVD association. Some of the most documented ones of these gene polymorphisms are patatin-like phospholipase domain-containing protein 3 (PNPLA3), transmembrane 6 superfamily member 2 (TM6SF2), hydroxysteroid 17-beta dehydrogenase 13 (HSD17B13), adiponectin-encoding gene (ADIPOQ), apolipoprotein C3 (APOC3), peroxisome proliferator-activated receptors (PPAR), leptin receptor (LEPR), sterol regulatory element-binding proteins (SREBP), tumor necrosis factor-alpha (TNF-α), microsomal triglyceride transfer protein (MTTP), manganese superoxide dismutase (MnSOD), membrane-bound O-acyltransferase domain-containing 7 (MBOAT7), and mutation in DYRK1B that substitutes cysteine for arginine at position 102 in kinase-like domain. Further cohort studies with a significant sample size using advanced genomic assessments and next-generation sequencing techniques are needed to shed more light on genetic associations between NAFLD and CVD.

Abstract
BACKGROUND Hepatitis C virus (HCV) is an important cause of liver cirrhosis and its complications. The safety and efficacy of bariatric surgery in patients with HCV infection is not clear. METHODS Charts were reviewed to identify patients with HCV infection before bariatric surgery. Bariatric surgical patients with non-alcoholic steatohepatitis (NASH) and without NASH (non-NASH) were recruited as comparative groups. Demographic variables, perioperative data, follow-up, and HCV-related parameters were extracted and compared. RESULTS Forty-seven bariatric patients between 2000 and 2016 that suffered from HCV infection were identified. The mean age and body mass index (BMI) at baseline were 34.5 ± 9.9 years and 40.4 ± 7.7 kg/m2, respectively. The HCV(+) group was associated with female sex, older age, lower BMI, and waist circumference than both NASH and non-NASH groups. Both HCV(+) and NASH groups had higher liver function tests and incidence of metabolic syndrome than non-NASH group. The HCV(+) group had lower uric acid and albumin level than the NASH group. Early major postoperative complication occurred in 1 (2.1%) patient of the HCV(+) group. At follow-up, the mean BMI decreased to 29.1 ± 7.1 kg/m2 and total weight loss was 25% for the HCV(+) group at 5 years after surgery. The weight loss curves were similar between the HCV(+) group and NASH group. During follow-up, no patients died but one patient with HCV(+) developed flare up of hepatitis after gastric bypass. The mean liver transaminase level remained in normal range for the HCV(+) group. CONCLUSION Co-existence of HCV infection does not influence the outcome of bariatric surgery but continued monitoring of the liver function is indicated.

Abstract
The hepatitis B virus (HBV) infects approximately 240 million people worldwide, causing chronic liver disease (CLD) and liver cancer. Although numerous studies have been performed to date, unfortunately there is no conclusive drug or treatment for HBV induced liver disease. The hepatitis B virus X (HBx) is considered a key player in inducing CLD and hepatocellular carcinoma (HCC). We generated transgenic (Tg) mice expressing HBx protein, inducing HCC at the age of 11–18 months. The incidence of histological phenotype, including liver tumor, differed depending on the genetic background of HBx Tg mice. Fatty change and tumor generation were observed much earlier in livers of HBx Tg hybrid (C57BL/6 and CBA) (HBx-Tg hybrid) mice than in HBx Tg C57BL/6 (HBx-Tg B6) mice. Inflammation was also enhanced in the HBx-Tg B6 mice as compared to HBx-Tg hybrid mice. HBx may be involved in inducing and promoting hepatic steatosis, glycemia, hepatic fibrosis, and liver cancer. Reactive oxygen species (ROS) generation was remarkably increased in livers of HBx Tg young mice compared to young wild type control mice. Previous studies on HBx Tg mice indicate that the HBx-induced ROS plays a role in inducing and promoting CLD and HCC.

Abstract
Chronic liver disease (CLD) is a major health problem worldwide. Non-alcoholic fatty liver disease (NAFLD), chronic hepatitis C (CHC), chronic hepatitis B (CHB), and alcoholic liver disease (ALD) are the most common etiologies of CLD. Liver biopsy is the gold standard for assessment of liver fibrosis, however, it is an invasive method. This review attempts to evaluate the usefulness of serum adiponectin, serum leptin, serum ferritin, serum transforming growth factor-β1 (TGF-β1), and serum platelet derived growth factor-BB (PDGF-BB) as non-invasive markers in the diagnosis of liver fibrosis/cirrhosis. A systematic search in MEDLINE, Web of Science, Scopus, and local databases was performed to identify articles published in English or Persian as of November 2017. Studies conducted among CLD patients, with biopsy proven fibrosis/cirrhosis, and providing sufficient details of patients' clinicopathological characteristics were included. In the 95 studies included, there were a total of 15,548 CLD patients. More than 83% of studies were carried out in Asia and Europe. The relationship between liver fibrosis/cirrhosis and serum levels of ferritin, adiponectin, leptin, TGF-β1, and PDGF-BB was assessed in 42, 33, 27, nine, and three studies, respectively. Serum levels of the markers, particularly ferritin, could successfully predict liver fibrosis/cirrhosis, however, these data might not be clinically replicated and further studies are needed.

Azarkar G, Doosti Z, Osmani F, Ziaee M. Analysis Of Risk Factors For Nonalcoholic Fatty-Liver Disease In Hepatitis B Virus Infection: A Case-Control Study. Hepat Med 2019; 11:153-158. [PMID: 31749640 PMCID: PMC6818534 DOI: 10.2147/hmer.s211106] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/03/2019] [Accepted: 09/17/2019] [Indexed: 12/29/2022] Open
Abstract
Background Nonalcoholic fatty-liver disease (NAFLD) is the most common cause of chronic liver disease worldwide. Although NAFLD has been studied extensively, potential risk factors for NAFLD among chronic hepatitis B (CHB) patients and their comparison with healthy individuals have remained understudied in Iran. As such, we examined the association between HBV infection and the development of NAFLD in two groups. Methods A case-control study was done on 376 CHB patients and 447 healthy subjects randomly selected from Birjand, South Khorasan province, Iran. We used logistic regression to estimate adjusted ORs with 95% CIs for incidence of NAFLD. Potential risk factors for NAFLD were evaluated while adjusting for age, sex, marital status, and educational level. Also, χ 2 was used to compare demographic characteristics between the two groups. Results A total of 373 CHB patients (mean age 40.1±12.9 years) versus 447 individuals in the control group (mean age 39.8±13.9 years) were included in this study (p=0.337). Liver characteristics were found to be significantly different in CHB and healthy groups (p<0.05). According to the results obtained from logistic regression, the adjusted OR (95% CI) for NAFLD incidence of comparing HBsAg-positive to HBsAg-negative participants was 0.62 (0.45-0.84). Conclusion The results suggested that HBsAg seropositivity was associated with lower risk of developing NAFLD. This study also revealed that mild cases of fatty liver in carriers of hepatitis B are more common than in healthy subjects. However, moderate and severe cases of this condition are more common in healthy people than in hepatitis B carriers.

Abstract
Nonalcoholic fatty liver disease (NAFLD), the most common liver disorder worldwide, is epidemiologically associated with overweight, insulin resistance features and type 2 diabetes, and can progress to advanced liver fibrosis and hepatocellular carcinoma. Genetic factors play an important role in the development of NAFLD, which is a multifactorial disease. Several common naturally occurring variants modulating lipid and retinol metabolism in hepatocytes predispose to NAFLD development and progression, in particular those in PNPLA3, TM6SF2, MBOAT7, and HSD17B13. In addition, genetic variants that protect hepatic cells from oxidative stress modulate the susceptibility to progressive NAFLD. Although the molecular mechanisms linking these genetic variants with liver disease are not yet fully understood, hepatic fat has emerged as a major driver of the disease, while altered retinol metabolism and mitochondrial oxidative stress play a role in determining the development of advanced NAFLD.

Abstract
Hepatitis B virus (HBV) infection and aflatoxin B1 (AFB1) exposure have been recognized as independent risk factors for the occurrence and exacerbation of hepatic steatosis but their combined impacts and the potential mechanisms remain to be further elucidated. Here, we showed that exposure to AFB1 impaired mitochondrial dynamics and increased intracellular lipid droplets (LDs) in the liver of HBV-transgenic mice in vivo and the hepatitis B virus X protein (HBx)-expressing human hepatocytes both ex vivo and in vitro. HBx combined with AFB1 exposure also up-regulated receptor interaction protein 1 (RIP1), receptor interaction protein 3 (RIP3) and activated mixed lineage kinase domain like protein (MLKL), providing evidence of necrosome formation in the hepatocytes. The shift of the mitochondrial dynamics towards imbalance of fission and fusion was rescued when MLKL was inhibited in the HBx and AFB1 co-treated hepatocytes. Most importantly, based on siRNA or CRISPR/Cas9 system, we found that the combination of HBx and AFB1 exposure increased cyclooxygenase-2 (COX-2) to mediate up-regulation of RIP3 and dynamin-related protein 1 (Drp1), which in turn promoted location of RIP3-MLKL necrosome on mitochondria, subsequently exacerbated steatosis in hepatocytes. Taken together, these findings advance the understanding of mechanism associated with HBx and AFB1-induced hepatic necrosome formation, mitochondrial dysfunction and steatosis and make COX-2 a good candidate for treatment.

Moderate to severe hepatic steatosis leads to overestimation of liver stiffness measurement in chronic hepatitis B patients without significant fibrosis. Aliment Pharmacol Ther 2019; 50:93-102. [PMID: 31094016 DOI: 10.1111/apt.15298] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/07/2018] [Revised: 11/29/2018] [Accepted: 04/19/2019] [Indexed: 12/15/2022]
Abstract
BACKGROUND Liver stiffness measurement (LSM) by transient elastography is a noninvasive method for the diagnosis of hepatic fibrosis. The impact of hepatic steatosis on LSM remains to be explored. AIM To determine whether LSM is affected by hepatic steatosis in patients with chronic hepatitis B (CHB). METHODS Consecutive patients with biopsy-proven CHB were prospectively enrolled. Hepatic steatosis was classified by pathology as none (S0, <5%), mild (S1, 5%-33%), and moderate-severe (S2-3, >33%), and quantitatively by controlled attenuation parameter (CAP) as CAP S0 (≤247 dB/m), CAP S1 (248-267 dB/m) and CAP S2-3 (≥268 dB/m). Liver fibrosis was assessed by METAVIR classification and noninvasively by LSM. RESULTS The prevalence of non-alcoholic fatty liver disease (n = 223) in CHB patients (n = 593) was 37.6%. Forty-eight belonged to S2-3 and 127 belonged to CAP S2-3. In patients without significant fibrosis (F0-1), the median LSM (kPa) was 7.4 in S2-3 and 7.1 in CAP S2-3, which was significantly higher than that in S0/S1 (P = 0.005) and CAP S0/S1 (P = 0.003). No significant difference was found in significant fibrosis (F2-4). For LSM identifying significant fibrosis (F2-4), the negative predictive value was higher in CHB patients with CAP ≥ 268 compared to those with CAP < 268 (0.81 vs 0.73); the positive predictive value was lower in CAP ≥ 268 than its counterpart (0.65 vs 0.76). CONCLUSIONS Moderate-severe steatosis increased the LSM value in CHB patients without significant fibrosis. A CAP ≥ 268 did not affect LSM for ruling out, but it slightly affected LSM for ruling in significant fibrosis. TRIAL REGISTRATION ChiCTR-DDT-13003983.

Abstract
Previous studies have demonstrated that the selective cyclooxygenase-2 (COX-2) inhibitor celecoxib shows efficacy against multiple cancers, including hepatocellular carcinoma. However, whether celecoxib is effective in alleviating steatosis during hepatocarcinogenesis is unknown. In a rapid hepatocellular carcinoma (HCC) mouse model established via hydrodynamic transfection of activated forms of AKT and c-Met proto-oncogenes, we investigated the antisteatotic and anticarcinogenic efficacy of celecoxib in vivo. Multiple HCC cell lines were employed for in vitro evaluation. Additionally, immunoblotting, immunohistochemistry, hematoxylin and eosin staining and Oil Red O staining were applied for mechanistic investigation. The results revealed that if celecoxib was administered in the early stage of AKT/c-Met-induced HCC, it resulted in disease stabilization. Moreover, celecoxib could alleviate lipid accumulation in the HCC mice and in an oleic acid-induced in vitro hepatic steatosis model. Further evidence at the molecular level indicated that celecoxib down-regulated the expression of phospho-ERK (Thr202/Tyr204) and proliferating cell nuclear antigen (PCNA) in the HCC mice. In addition, celecoxib efficiently repressed the phosphor-Akt (Thr308)/fatty acid synthase (FASN) axis both in vivo and in vitro. Altogether, this study suggests that celecoxib exerts its antilipogenic efficacy by targeting a COX-2/AKT/FASN cascade, which contributes to its ability to delay hepatocarcinogenesis.

Abstract
The hepatitis C virus (HCV) is the most common blood-borne infection in the United States and is the most common cause of end-stage liver disease requiring liver transplant. Over the last 10 years, direct acting antiviral therapies have revolutionized HCV treatment, increasing the cure rates from less than 50% to more than 90% in those who reach access to care. This article is an overview for pathologists and clinicians covering the histologic findings of HCV as well as direct acting antiviral therapy.

Abstract
Abstract
Background: Due to the inherently unstable nature of HCV, various genotypes have been identified. Steatosis is a histological feature in the progression of HCV-associated liver disease and has been shown to alter the host lipid metabolism. Objective: Assess the distribution of HCV genotypes in the two provinces of Pakistan, and determine the association of hepatic steatosis with altered clinical and virological factors in chronic HCV patients. Methods: One hundred twenty six chronic HCV patients (steatosis in 49 patients) were enrolled for qualitative analysis by PCR. Out of 126 ELISA and PCR positive samples, 119 (48 with hepatic steatosis) chronic HCV patients (mean age 42.0±13.3 years, mean body mass index (BMI) 24.2±4.1) were proved positive after PCR-based detection. Biochemical and virological factors such as HCV genotype, or glucose, in 119 CHC patients were determined and compared between patients with and without hepatic steatosis. Results: Out of 126 samples, 119 were HCV positive, where 58 (48.7%) were genotype 3a, 24 (20.2%) were 3b, 12 (10.1%) were 1a, eight (6.7%) were 2a, six (5.0%) were 1b, and one (0.8%) was 4. Furthermore, seven (5.9%) had a co-infection and three (2.5%) were untypable. BMI (p=0.004), genotype 3a (p<0.001), and triglycerides (p=0.002) were significantly associated with steatosis. It is noteworthy that cholesterol (p=0.281), glucose (p=0.305), lowdensity lipoprotein (p=0.101), high-density lipoprotein (p=0.129), alanine amino transferase (p=0.099), aspartate transaminase (p=0.177), bilirubin (p= 0.882), and age (p=0.846) showed non-significant association. Conclusion: Genotype 3a is the predominant genotype in Pakistan. Hepatic steatosis is quite frequent feature in HCV patients and strongly correlates with BMI, genotype 3a, and triglyceride contents in patients infected with HCV.

Abstract
Abstract
Background: Hypoadiponectinemia and hyperleptinemia, and reductions in the ratio of adiponectin to leptin (A/L ratio) are associated with the development of hepatic necroinflammation in nonalcoholic fatty liver, but the association of the adipokines with hepatic steatosis in chronic viral hepatitis is unclear.
Objective: To investigate the relationship between serum A/L ratio, insulin resistance, degree of hepatic steatosis, and necroinflammation in patients with chronic viral hepatitis.
Methods: We measured serum adiponectin, leptin, and resistin levels, insulin resistance, and analyzed the association between liver histopathology and the level of the adipokines in 44 patients with chronic viral hepatitis before they started treatment.
Results: We found that insulin resistance, leptin, and resistin levels tended to increase in the group with a greater degree of hepatic steatosis and necroinflammation, but that the increase was not significant. The adiponectin/leptin ratio (A/L ratio) in a group with a low degree of hepatic steatosis was significantly higher than it was in the group with a high degree of hepatic steatosis (3.1 ± 3.1 vs 1.2 ± 0.8; P = 0.008). The A/L ratio in a group with low histological activity index (HAI) scores was significantly higher than in the group with high HAI scores (3.7 ± 3.4 vs 1.1 ± 1.1; P = 0.006). Abdominal obesity was the only variable that showed a significant association with the HAI score (P = 0.03).
Conclusion: The serum A/L ratio in patients with chronic viral hepatitis showed a significant inverse association with their degree of hepatic steatosis and necroinflammation.

Abstract
Only scarce data on liver steatosis in children with chronic hepatitis B and C (CHB and CHC) are available. The objective of this study was to evaluate the prevalence, predictors, and impact of hepatic steatosis on children with CHB and CHC. A total of 78 patients aged 11.5 ± 3.4 years were included: 30 (38%) had CHB, and 48 (62%) had CHC. Steatosis was scored on a 5-point scale, as follows: absent; minimal (≤5% hepatocytes affected), mild (6-33%), moderate (34-66%), and severe (>66%). Stepwise logistic regression was used to determine the factors associated with steatosis and moderate-to-severe steatosis. Steatosis was observed in 4/30 (13%) patients with CHB and 13/48 (27%) patients with CHC (P = 0.17). Moderate-to-severe steatosis was observed in 6/78 (8%) patients: 1/30 (3%) had CHB and 5/48 (10%) had CHC (P = 0.40). The body mass index (BMI) z-score was positively associated with the presence of steatosis in children with CHB (odds ratio [OR] = 3.3, 95% confidence interval [CI]: 1.02-10.64). In CHC, steatosis occurred more frequently in patients with hepatitis C virus genotype 3 compared with other genotypes (P = 0.002). In patients with non-3 genotype hepatitis C virus, steatosis was associated with the stage of fibrosis (OR = 3.35, 95% CI: 1.01-11.07) and inversely associated with the duration of infection (OR = 0.74, 95% CI: 0.55-0.97). Moderate-to-severe steatosis was positively associated with the BMI z-score (OR = 3.62, 95% CI: 1.22-10.75) and stage of fibrosis (OR = 3.89, 95% CI: 1.05-14.47). Steatosis is a common finding in children with chronic viral hepatitis. It is associated with metabolic factors in CHB, whereas in patients with CHC, metabolic and viral factors may have a combined effect, leading to more advanced grades of steatosis in children with higher BMI z-scores. Moderate-to-severe steatosis is a predictor of advanced fibrosis in children with CHC.

Abstract
AIM We aimed study impact of hepatocytic viral load, steatosis, and iron load on fibrosis in chronic hepatitis C and role of VEGF and VEGFR overexpression in cirrhotic cases in evolving HCC. MATERIAL AND METHODS Total of 120 cases were included from TBRI and Beaujon Hospital as chronic hepatitis C (CHC), post-hepatitis C cirrhosis, and HCC. Cases of CHC were stained for Sirius red, Prussian blue and immunohistochemically (IHC) for HCV-NS3/NS4. HCC were stained IHC for VEGF and by FISH. RESULTS Stage of fibrosis was significantly correlated with inflammation in CHC (P < 0.01). Noticed iron load did not correlate with fibrosis. Steatosis was associated with higher inflammation and fibrosis. The cellular viral load did not correlate with inflammation, steatosis or fibrosis. VEGF by IHC was significantly higher in cases of HCC when compared to cirrhotic group (P < 0.001). Amplification of VEGFR2 was confirmed in 40% of cases of HCC. Scoring of VEGF by IHC was the good indicator of VEGFR2 amplification by FISH (P < 0.005). CONCLUSION Grade of inflammation is the factor affecting fibrosis in CHC. The degree of liver damage is not related to cellular viral load or iron load. Steatosis is associated with higher inflammation and fibrosis. VEGF by IHC is correlated with overexpression of VEGFR2 by FISH.

Abstract
Purpose To further observe and verify the effect of nonalcoholic fatty liver disease (NAFLD) on the response to antiviral therapy in patients with chronic hepatitis B (CHB) and investigate the relationship between the virologic response and insulin resistance. Patients and methods A retrospective study was adopted and 61 NAFLD patients with HBeAg-positive CHB were included as the observation group (group A), and 64 patients with simple CHB were included as the control group (group B). Results After 12 weeks of treatment with entecavir, the total virologic response rate in group A was statistically significantly lower than that in group B (P<0.05). During weeks 24–96, the difference was not statistically significant (P>0.05). In weeks 48 and 96, there was no significant difference in the HBeAg seroconversion rates between the two groups (P>0.05). In weeks 12 and 24, there was also no significant difference in the alanine transaminase (ALT) normalization rate between the two groups (P>0.05). Then, in weeks 48 and 96, the ALT normalization rate of group A was obviously lower than that of group B (P<0.05). Group A patients were divided into group A1 (≤M) and group A2 (>M) according to the median value (M=2.79) of the baseline homeostatic model assessment method insulin resistance levels. In weeks 48 and 96, the ALT normalization rate of group A1 was significantly higher than that of group A2 (P<0.05). The correlation coefficient (r) of the baseline homeostatic model assessment method insulin resistance level and the severity of fatty liver in group A was 0.426 (P=0.001). Conclusion NAFLD cannot affect the long-term total virologic response rate and HBeAg seroconversion rate in CHB patients treated with entecavir but can reduce the long-term biochemical response rate, which has a positive correlation with the severity of fatty liver and the insulin resistance index.

Abstract
BACKGROUND AND AIMS This study sought to evaluate the impact of hepatic steatosis, a common hepatocyte change in nonalcoholic fatty liver disease, upon response to pegylated interferon (PEG-IFN) therapy in patients with chronic hepatitis B (CHB). METHODS Eighty-nine consecutive CHB patients from the Affiliated Hospital of Hangzhou Normal University receiving 48 weeks of PEG-IFN therapy were enrolled in this study, and 56 patients were followed up for 48 weeks among subjects with completed therapy. Baseline characteristics, end-of-treatment response (ETR), and sustained viral response (SVR) to PEG-IFN therapy were evaluated. Univariate analysis and multivariate logistic regression were applied to find independent factors of hepatic steatosis and PEG-IFN treatment failure. RESULTS Steatosis was present in 34.5% (31 of 89) of liver biopsy samples. ETR to PEG-IFN therapy was 56.17% (50 of 89) at 48 weeks, and SVR to PEG-IFN therapy was 57.6% (32 of 56) at 96 weeks. There was no significant difference in ETR between the patients with hepatic steatosis and those without hepatic steatosis at 48 weeks (P > .05), whereas SVR was higher in patients without hepatic steatosis than in those with hepatic steatosis at 96 weeks (P < .05). Multivariate analysis showed that the sustained response rate was independently associated with steatosis, fibrosis, aspartate aminotransferase, C-reactive protein, and ferritin. Hepatic steatosis was a prediction factor with the sustained response. CONCLUSIONS Hepatic steatosis may be a predictive factor of response to PEG-IFN therapy in patients with CHB.

Abstract
UNLABELLED A genome-wide exome association study has identified the transmembrane 6 superfamily member 2 (TM6SF2) rs58542926 variant encoding an E167K substitution as a genetic determinant of hepatic steatosis in nonalcoholic fatty liver disease (NAFLD). The roles of this variant across a spectrum of liver diseases and pathologies and on serum lipids comparing viral hepatitis to NAFLD and viral load in chronic viral hepatitis, as well as its intrahepatic molecular signature, have not been well characterized. We undertook detailed analyses in 3260 subjects with viral and nonviral liver diseases and in healthy controls. Serum inflammatory markers and hepatic expression of TM6SF2 and genes regulating lipid metabolism were assessed in a subset with chronic hepatitis C (CHC). The rs58542926 T allele was more prevalent in 502 NAFLD patients than controls (P = 0.02) but not different in cohorts with CHC (n = 2023) and chronic hepatitis B (n = 507). The T allele was associated with alterations in serum lipids and hepatic steatosis in all diseases and with reduced hepatic TM6SF2 and microsomal triglyceride transfer protein expression. Interestingly, the substitution was associated with reduced CHC viral load but increased hepatitis B virus DNA. The rs58542926 T allele had no effect on inflammation, impacted ≥F2 fibrosis in CHC and NAFLD assessed cross-sectionally (odds ratio = 1.39, 95% confidence interval 1.04-1.87, and odds ratio = 1.62, 95% confidence interval 1.03-2.52, respectively; P < 0.03 for both), but had no effect on fibrosis progression in 1174 patients with CHC and a known duration of infection. CONCLUSION The TM6SF2 E167K substitution promotes steatosis and lipid abnormalities in part by altering TM6SF2 and microsomal triglyceride transfer protein expression and differentially impacts CHC and chronic hepatitis B viral load, while effects on fibrosis are marginal.

Abstract
Worldwide, nonalcoholic fatty liver disease (NAFLD) has a high prevalence with the rising rates of overweight and/or obesity. Chronic hepatitis B (CHB) virus infection is another common cause of infectious liver diseases. In practice, the overlap between NAFLD and CHB is rather common. In this review, we summarize the relationship between NAFLD and CHB, the influence of NAFLD on CHB, and the role of the metabolic syndrome in the development of hepatic fibrosis, cirrhosis and hepatocellular carcinoma. Recent advances in understanding the reason CHB is prone to overlap NAFLD will be discussed. The adverse effects caused by NAFLD on the treatment and progression of CHB will be also elucidated. NAFLD overlapping CHB often raises a great challenge to the clinicians, in terms of diagnosis or treatment. Therefore, appropriate management of this complex situation is needed.

Abstract
The prevalence of fatty liver (steatosis) in the general population is rapidly increasing worldwide. The progress of knowledge in the physiopathology of fatty liver is based on the systems biology approach to studying the complex interactions among different physiological systems. Similarly, translational and clinical research should address the complex interplay between these systems impacting on fatty liver. The clinical needs drive the applications of systems medicine to re-define clinical phenotypes, assessing the multiple nature of disease susceptibility and progression (e.g. the definition of risk, prognosis, diagnosis criteria, and new endpoints of clinical trials). Based on this premise and in light of recent findings, the complex mechanisms involved in the pathology of fatty liver and their impact on the short- and long-term clinical outcomes of cardiovascular, metabolic liver diseases associated with steatosis are presented in this review using a new "systems medicine" approach. A new data set is proposed for studying the impairments of different physiological systems that have an impact on fatty liver in different subsets of subjects and patients.

Hepatitis B Virus X Protein Induces Hepatic Steatosis by Enhancing the Expression of Liver Fatty Acid Binding Protein. J Virol 2015; 90:1729-40.

Abstract
UNLABELLED Hepatitis B virus (HBV) has been implicated as a potential trigger of hepatic steatosis although molecular mechanisms involved in the pathogenesis of HBV-associated hepatic steatosis still remain elusive. Our prior work has revealed that the expression level of liver fatty acid binding protein 1 (FABP1), a key regulator of hepatic lipid metabolism, was elevated in HBV-producing hepatoma cells. In this study, the effects of HBV X protein (HBx) mediated FABP1 regulation on hepatic steatosis and the underlying mechanism were determined. mRNA and protein levels of FABP1 were measured by quantitative RT-PCR (qPCR) and Western blotting. HBx-mediated FABP1 regulation was evaluated by luciferase assay, coimmunoprecipitation, and chromatin immunoprecipitation. Hepatic lipid accumulation was measured by using Oil-Red-O staining and the triglyceride level. It was found that expression of FABP1 was increased in HBV-producing hepatoma cells, the sera of HBV-infected patients, and the sera and liver tissues of HBV-transgenic mice. Ectopic overexpression of HBx resulted in upregulation of FABP1 in HBx-expressing hepatoma cells, whereas HBx abolishment reduced FABP1 expression. Mechanistically, HBx activated the FABP1 promoter in an HNF3β-, C/EBPα-, and PPARα-dependent manner, in which HBx increased the gene expression of HNF3β and physically interacted with C/EBPα and PPARα. On the other hand, knockdown of FABP1 remarkably blocked lipid accumulation both in long-chain free fatty acids treated HBx-expressing HepG2 cells and in a high-fat diet-fed HBx-transgenic mice. Therefore, FABP1 is a key driver gene in HBx-induced hepatic lipid accumulation via regulation of HNF3β, C/EBPα, and PPARα. FABP1 may represent a novel target for treatment of HBV-associated hepatic steatosis. IMPORTANCE Accumulating evidence from epidemiological and experimental studies has indicated that chronic HBV infection is associated with hepatic steatosis. However, the molecular mechanism underlying HBV-induced pathogenesis of hepatic steatosis still remains to be elucidated. In this study, we found that expression of liver fatty acid binding protein (FABP1) was dramatically increased in the sera of HBV-infected patients and in both sera and liver tissues of HBV-transgenic mice. Forced expression of HBx led to FABP1 upregulation, whereas knockdown of FABP1 remarkably diminished lipid accumulation in both in vitro and in vivo models. It is possible that HBx promotes hepatic lipid accumulation through upregulating FABP1 in the development of HBV-induced nonalcoholic fatty liver disease. Therefore, inhibition of FABP1 might have therapeutic value in steatosis-associated chronic HBV infection.

Abstract
BACKGROUND The patatin-like phospholipase domain-containing 3 gene (PNPLA3) has been associated with liver steatosis and disease progression in nonalcoholic steatohepatitis and chronic hepatitis C. AIMS The aim of the present study was to evaluate the influence of the PNPLA3 I148M polymorphisms on the clinical, histological, viral, and host parameters in Italian patients with chronic hepatitis B (CHB). METHODS Ninety-nine patients with CHB entered the study and underwent a clinical, histological, virological, and biochemical evaluation. PNPLA3 (p.I148M) variants were genotyped. RESULTS PNPLA3 rare variant (148M) was significantly associated with liver steatosis (p = 0.0019) and cholesterol (p = 0.04) levels, but not with fibrosis or histological activity index. The 13 patients with severe liver steatosis (score > 3) (38%) were more frequently homozygous for PNPLA3 148M variant than the 86 without (6%, p = 0.003). At logistic regression analysis, severe steatosis was independently associated with the rare allele (p = 0.001) and waist circumference, but not with body mass index (BMI). CONCLUSIONS In our CHB patients, the PNPLA3 polymorphisms influenced the development of liver steatosis, but not fibrosis status. The association of PNPLA3 p.I148M with liver steatosis increased with the greater amount of abdominal fat, irrespective of BMI.

Abstract
Background End-stage liver disease and hepatocellular carcinoma due to hepatitis C virus (HCV) co-infection are increasingly common causes of death among HIV-infected individuals. However, there are few clinical investigations of HIV/HCV co-infected individuals from low and middle-income nations. Here, we compare the epidemiology of HCV-infected and HIV/HCV co-infected individuals in Southern China and examine hepatic fibrosis scores in co-infected individuals. Methods We conducted a retrospective cross-sectional study of treatment-naïve HIV/HCV co-infected and HCV mono-infected subjects. Bivariate and multivariate models were used to examine the association between demographics and HCV genotype. Among co-infected individuals, we also studied the relationship between fibrosis scores derived from non-invasive studies and HCV genotype. Results Data were collected from 175 HCV-infected individuals, including 89 (51 %) HIV/HCV co-infected individuals. HIV/HCV co-infection was correlated with intravenous drug use (AOR 46.25, p < 0.001) and not completing high school (AOR 17.39, p < 0.001) in a multivariate model. HIV/HCV co-infected individuals were more likely to be infected with HCV genotype 6a (p < 0.0001) or 3a (p < 0.023), whereas increased fibrosis (FIB-4 score) was associated with HCV genotype 3a infection (β 2.18, p < 0.001). Discussion Our results suggest that intravenous drug use is driving HIV/HCV co-infection in Southern China. While additional studies are needed, HCV genotype 6a is more common and genotype 3a appears to be associated with more severe hepatic fibrosis in co-infected individuals. Conclusions Future HIV/HCV co-infection research in China should focus on at risk populations, HCV testing uptake, and genotype-specific treatment.

Abstract
OBJECTIVES The incidence of non-alcoholic fatty liver disease (NAFLD) is significant in hepatitis C virus (HCV) carriers due to multiple mechanisms, and this worsens the progression of chronic liver diseases, such as cirrhosis and hepatocellular carcinoma, and death. The purpose of this study was to examine whether the alanine aminotransferase/aspartate aminotransferase (ALT/AST) ratio correlates with the status of hepatosteatosis. DESIGN A cross-sectional observational study. SETTING Community-based annual examination in northern Taiwan. PARTICIPANTS A total of 1354 participants (age 20 years or over) were enrolled after excluding participants with HCV seronegative, laboratory or questionnaires loss, moderate alcohol consumption, liver cirrhosis, tumours and postlobectomy. OUTCOME MEASURES Fatty liver was diagnosed according to echogenic findings. NAFLD included grades 1-3 fatty liver and high-degree NAFLD defined grades 2-3 fatty liver. RESULTS 580 males and 774 females with a mean age of 47.2 (SD=16.1) years were cross-sectionally studied. The participants with NAFLD have significantly higher levels of ALT/AST ratio, fasting glucose, triglyceride and systolic/diastolic blood pressure than non-NAFLD participants. The association between NAFLD and ALT/AST was significant even when adjusting for the metabolic syndrome (aOR 1.90; 95% CI 1.37 to 2.65; p<0.001). In patients with a high degree of NAFLD, the ALT/AST ratio was still a significant predictor for hepatosteatosis (aOR 2.44; 95% CI 1.58 to 3.77; p<0.001). CONCLUSIONS The ALT/AST ratio could be a strong risk of hepatosteatosis in patients with chronic HCV infection.

Abstract
BACKGROUND AND AIM Chronic hepatitis C virus (HCV) infection has been suggested to be associated with non-insulin-dependent diabetes mellitus and lipid profiles. This study aimed to investigate the possible relationships of insulin resistance (IR) and lipid profiles with chronic hepatitis C (CHC) patients in Taiwan. METHODS We enrolled 160 hospital-based CHC patients with liver biopsy and the 480 controlled individuals without CHC and chronic hepatitis B from communities without known history of non-insulin-dependent diabetes mellitus. Fasting plasma glucose, total cholesterol, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triglycerides (TGs), alanine aminotransferase, and serum insulin levels, and homeostasis model assessment (HOMA-IR) were tested. RESULTS When comparing factors between CHC patients, and sex- and age-matched controls who had no HCV infection, patients with HCV infection had a significantly higher alanine aminotransferase level, fasting plasma glucose level, insulin level, and HOMA-IR (P < 0.001, P = 0.023, P = 0.017, and P = 0.011, respectively), and significantly lower TG level (P = 0.023), total cholesterol, and HDL-C and LDL-C levels (all P < 0.001) than 480 controls. In multivariate logistic regression analyses, a low total cholesterol, a low TGs, and a high HOMA-IR are independent factors significantly associated with chronic HCV infection. In the 160 CHC patients (41 patients with high HOMA-IR [> 2.5]), a high body mass index, TGs, and HCV RNA level are independent factors significantly associated with high HOMA-IR in multivariate logistic analyses. CONCLUSIONS Chronic HCV infection was associated with metabolic characteristics including IR and lipid profile. IR was also associated with virological characteristics.

Abstract
BACKGOUND/AIM Studies associating chronic hepatitis C virus (HCV) infection with lipid profile and hepatic steatosis in children and adolescents are scarce. This study investigated lipid profile abnormalities and hepatic steatosis among HCV-infected Egyptian children and adolescents who survived leukemia and lymphoma and evaluated impact on response to antiviral therapy. SUBJECTS AND METHODS Thirty-six leukemia/lymphoma cured children and adolescents (mean age: 12.47 ± 3.56 years) with chronic HCV infection and 30 healthy controls (mean age: 11.64 ± 3.96 years) were enrolled in this prospective study. Serum lipid profile and abdominal ultrasonography were done for all patients and controls. Guided liver biopsy with histopathological examination was done for 32 (88.9%) patients eligible for antiviral therapy. RESULTS Total cholesterol, LDL-cholesterol, and apolipoprotein B (apo-B) in patients were significantly lower than in the control group (P ≤ .01, ≤ .01, and ≤ .05, respectively). Among those who underwent liver biopsy (n = 32), macrovesicular hepatic steatosis associated with chronic hepatitis C was documented in 10 children (31.3%). Body mass index was significantly higher (P ≤ .05) and apo-B was significantly lower in steatotic (P ≤ .05) than non-steatotic HCV-infected children. Liver span by ultrasound, alanine aminotransferase (ALT), and apo-B were independent predictors for hepatic steatosis (P < .001, <.001, and <.05, respectively). A significantly worse response to interferon alpha 2-b plus ribavrin treatment for HCV was reported among children with steatosis (P < .001). CONCLUSIONS The study showed low serum lipids in HCV-infected children with cured leukemia/lymphoma. Hepatic steatosis was found in a significant proportion of patients and was associated with a poor response to antiviral treatment.

Abstract
OBJECTIVE Nutrition disorders in patients with chronic liver disease have become a recent concern because these disorders influence outcomes. We investigated patients' nutrition status, included consecutively in the last 2 years to the study, and related the results with the severity of liver disease. METHODS A total of 230 patients with hepatitis B (n = 80) or C (n = 150) were evaluated by the subjective global assessment (SGA) and body mass index (BMI). The risk of metabolic complications was assessed by waist circumference (WC) and the percentage of body fat (%BF). Alcohol abuse was defined as daily consumption >20 g and >30 g for women and men, respectively. RESULTS The mean age was 54 years, with 52.6% women, 75% patients without cirrhosis, and 15% patients with cirrhosis. According to the SGA, 86.5% of patients were nourished, and 13.5% were malnourished. Malnutrition was associated with cirrhosis (prevalence ratio [PR], 1.25; 95% confidence interval [CI], 1.1-1.4; P < .001), alcohol abuse, direct bilirubin >3.0 mg/dL, international normalized ratio >1.1, platelet <150 × 10(3)/mm(3), hemoglobin <12 g/dL, and serum albumin <3.5 g/dL (P < .05). According to the BMI, 43.9% of patients were eutrophic, 33.5% were overweight, 21.3% were obese, and 1.3% were underweight. Obese patients had a higher prevalence of steatosis than eutrophic (PR, 1.53; 95% CI, 1.15-2.04; P = .003) and overweight (PR, 1.71; 95% CI, 1.33-2.20; P < .001) patients. Overweight/obesity was associated with WC >94 cm (men) and >80 cm (women), %BF >25% (men) and >32% (women) (P < .01), triglyceride >150 mg/dL, high-density lipoprotein cholesterol <40 mg/dL, glucose >99 mg/dL, insulin >20 µU/mL, homeostatic model assessment-insulin resistance >3.2, and thyroid-stimulating hormone >2.5 µU/mL (P < .05). CONCLUSIONS Overweight/obesity is prevalent among patients with hepatitis B and C and can contribute to the development of steatosis. Malnutrition is also observed and is related to the severity of liver disease.

Abstract
INTRODUCTION Chronic hepatitis B virus (HBV) infection and liver steatosis (LS) are the most common causes of chronic liver disease, and their coexistence is frequently observed in clinical practice. Although metabolic syndrome is the main cause of LS, it has not been associated with HBV infection. The aims of this study were to describe the lipid profile and prevalence of LS among HBV carriers and to identify the characteristics associated with LS in this group. METHODS This retrospective cross-sectional study included hepatitis B surface antigen (HBsAg)-positive patients evaluated during 2011 and 2012. RESULTS Of the 83 patients included, the mean age was 46.4±12.5 years, 53% were men, and 9.1% were hepatitis B e antigen (HBeAg) -positive. These patients exhibited the following lipid profile: total cholesterol = 175.4±38.8mg/dL, low-density lipoprotein (LDL) = 113.0±32.7mg/dL, and triglycerides = 91.1±45.2mg/dL. Their fasting glucose was 95.3±14.5g/dL, and fasting insulin was 6.1±5.9µIU/mL. Liver steatosis was observed on abdominal ultrasound in 11.3% of individuals. Factors associated with the presence of LS included higher levels of total cholesterol, prothrombin activity, fasting insulin, and body mass index (BMI) as well as lower levels of aspartate aminotransferase (AST). CONCLUSIONS These findings suggest that LS in patients with chronic HBV appears to be a consequence of metabolic alterations and insulin action rather than of viral factors.

Abstract
Steatosis and insulin resistance (IR) are no more frequent in chronic hepatitis B (CHB) than in the general population. Although experimental studies suggest that the HBx protein induces liver fat, human studies have shown that steatosis and IR are related to coexistent metabolic risk factors, thus epidemiologically linked rather than virally induced. Diabetes and obesity are associated with advanced fibrosis and increased risk of hepatocellular carcinoma in CHB. Despite abundant experimental data showing that fatty liver is more susceptible to liver injury, drug-induced liver disease seems no more frequent in NAFLD patients, except, possibly, a higher incidence but not severity of acetaminophen hepatotoxicity.

Abstract
UNLABELLED Steatosis is a common histopathological feature of chronic hepatitis B (CHB) and has been associated with severity of liver disease. Recently, the rs738409 I148M patatin-like phospholipase domain-containing 3 (PNPLA3) polymorphism has been demonstrated to influence steatosis susceptibility and fibrosis progression in patients with different liver diseases, but no data are yet available for CHB. The aim of this study was to evaluate whether PNPLA3 I148M influences steatosis susceptibility in a large series of patients with CHB. We enrolled 235 treatment-naïve CHB patients consecutively examined by percutaneous liver biopsy. In ≥2-cm-long liver tissue cores, steatosis and fibrosis were staged by Kleiner and METAVIR scores, respectively. The I148M polymorphism was determined by Taqman assays. Steatosis was present in 146 (62%) patients, of whom 24 (10%) had severe (>33% of hepatocytes) steatosis. Steatosis was independently associated with age (odds ratio [OR]: 2.67; confidence interval [CI]: 1.50-4.92; for age ≥50 years), body mass index (BMI; OR, 2.84; CI, 1.30-6.76; for BMI ≥27.5 kg/m(2) ), diabetes or impaired fasting glucose (OR, 4.45; CI, 1.10-30.0), and PNPLA3 148M allele (OR, 1.62; CI, 1.00-7.00; for each 148M allele). Independent predictors of severe steatosis were BMI (OR, 3.60; CI, 1.39-9.22; for BMI ≥27.5 kg/m(2) ) and PNPLA3 148M allele (OR, 6.03; CI, 1.23-5.0; for each 148M allele). PNPLA3 148M alleles were associated with a progressive increase in severe steatosis in patients with acquired cofactors, such severe overweight and a history of alcohol intake (P = 0.005). CONCLUSION In CHB patients, the PNPLA3 I148M polymorphism influences susceptibility to steatosis and, in particular, when associated with severe overweight and alcohol intake, severe steatosis.

Abstract
Estrogens exert a protective effect against hepatic steatosis and fibrosis. Loss of estrogen receptor-alpha (ER-α) in the liver is associated with hepatic steatosis and inflammation in animal models. We conducted a study in order to investigate the presence and extent of ER-α expression in HCV infection, and its relationship with histological and biochemical findings. Ninety biopsy-proven chronic hepatitis C (CHC) patients were enrolled in the study. Liver biopsy specimens were immunohistochemically stained for ER-α expression. Nuclear ER-α expression percentage was calculated. ER-α was positive in 69 of the patients (76%). ER-α positive and negative groups were not significantly different in terms of age, gender, necroinflammatory activity, fibrosis, steatosis, serum levels of AST, ALT, ALP, GGT, and bilirubin. ER-α expression percentage was not correlated with fibrosis, steatosis, necroinflammatory activity and biochemical findings. Although estrogens are known to be protective against fibrosis and steatosis in animal models, we did not find any significant correlation between ER-α expression and histopathological and biochemical findings in CHC patients. These findings should be verified in further large scale studies.

Abstract
BACKGROUND Steatosis is common in patients with hepatitis C virus (HCV) infection and may be a major determinant of progression of liver injury. This study evaluated FibroMax™ for noninvasive diagnosis of steatosis in patients with chronic HCV. METHODS This cross-sectional study included 44 patients naïve to treatment who were referred to our hepatology clinic for assessment of fitness for antiviral therapy. Chronic HCV infection was diagnosed by viral markers. Investigations included assessment of abdominal ultrasonography, liver biopsy, calculation of body mass index, and biomarker parameters in serum using FibroMax. RESULTS Histopathology of liver biopsies showed steatosis in 30 of 44 (68%) patients. FibroMax results were positively correlated with viral load by quantitative polymerase chain reaction and histopathological findings. Body mass index was significantly higher in steatotic patients (P = 0.003) and was significantly associated with the results on FibroMax (P = 0.005). CONCLUSION FibroMax was correlated with histopathology and body mass index in patients with HCV. Abdominal ultrasonography could not be used as a single tool to diagnose steatosis with HCV. Steatosis is correlated with viral load, which suggests a direct viral effect. We recommend FibroMax assessment in a larger number of patients to assess its applicability in patients with HCV and steatosis.

Abstract
OBJECTIVE This study aimed to explore clinical and virological characteristics of chronic hepatitis B (CHB) patients with hepatic steatosis in order to provide a theoretical basis for the prevention and control of hepatic steatosis. METHODS A total of 360 CHB inpatients were recruited from Affiliated Dongnan Hospital of Xiamen University and divided into hepatic steatosis group and non-hepatic steatosis group. The body mass index (BMI), waist-to-hip ratio (WHR), fasting blood glucose (FBG), triglyceride (TG), total cholesterol (TC), aminotransferase (AST), alanine aminotransferase (ALT), gamma-glutamyl transpeptidase (GGT), hepatitis B e antigen (HBeAg), hepatitis B virus DNA (HBV DNA) and hepatic histological changes were detected and compared between the two groups. The association of these factors with hepatic steatosis was evaluated in CHB patients. RESULTS BMI, FPG, TG, TC, GGT, AST and HBV DNA showed statistically significant differences between two groups (P<0.01). The patients with hepatic steatosis had markedly higher BMI, FBG, TG and TC than those without steatosis did. No significant differences were found in ALT and HBeAg between two groups (P>0.05). In male patients, there was marked difference in the WHR between two groups (P < 0.01), which was not found in female patients (P > 0.05). The severity of hepatic steatosis increased in patients with hepatic steatosis, compared to those without steatosis (P < 0.01), but the severities of inflammation and fibrosis in the non-hepatic steatosis group were dramatically higher than those in the hepatic steatosis group (P < 0.01). CONCLUSIONS BMI, WHR, FBG, TG and TC appeared to be influencing factors of CHB combined with hepatic steatosis. Hepatic steatosis in CHB patients was closely related to changes in anthropometric indices and metabolic factors but not HBV. It is necessary to improve these factors to effectively prevent hepatic steatosis in CHB patients.

Abstract
Enoyl-coenzyme A hydratase (ECHS1) is a key enzyme in the metabolism of fatty acids in mitochondria. We previously reported that hepatitis B surface antigen (HBsAg) interacted with ECHS1 in a yeast two-hybrid system. In the current study, we further examined their interaction by using GST pull-down and co-immunoprecipitation assays. The results confirmed that small hepatitis B surface antigen (SHBs) interacted with ECHS1. Furthermore, confocal imaging showed that SHBs and ECHS1 co-localized in HepG2 cells. To clarify the biological function of the interaction, human hepatoma cell lines that transiently and stably expressed SHBs were generated. The expression of SHBs led to a significant decrease in ECHS1 protein levels. ECHS1 protein levels were reduced to 48.44 ± 7.12 % in Huh7 cells transiently expressing SHBs, and to 54.97 ± 3.54 % in HepG2 cells stably expressing SHBs. In conclusion, our findings suggest that SHBs interacts with ECHS1 and regulates ECHS1 protein levels in hepatoma cells.

Abstract
BACKGROUND African Americans have lower reported likelihood of hepatitis C virus-related cirrhosis than whites. It is unknown whether relative differences in the distribution of adipose tissue, lean mass, and other anthropometric measurements may explain these observed interethnic differences in disease risk. AIM : To evaluate the association between anthropometric measurements and advanced liver disease in a cross-sectional study of African American and white male veterans. METHODS We used the validated FibroSURE-ActiTest to assess hepatic pathology, and direct segmental multichannel bioelectric impedance analysis for anthropometric measurements. Race-stratified logistic regression was employed to evaluate risk of high fibrosis progression rate (FPR) and advanced inflammation (A2 to A3). RESULTS Among 330 eligible males (59% African American), there were 43 white and 57 African American males with high FPR, and 70 African American and 59 white with advanced inflammation. Percentage body fat (%BF) was a stronger predictor of high FPR risk than was a high body mass index in African Americans [odds ratio (OR)(adj)=2.08; 95% confidence interval (CI),0.83-5.23 for highest %BF vs. lowest tertile and OR(adj)=1.50; 95% CI,0.60-3.75 for obese vs. normal body mass index, respectively], but not in whites. Highest lean leg mass was associated with a nonsignificant increased risk of both high FPR and advanced inflammation in African Americans (OR(highFPRadj)=1.73; 95% CI, 0.73-4.10; OR(AdvancedinflammationAdj)=1.65; 95% CI, 0.76-3.56) versus a decreased risk of both in whites (OR(highFPRadj)=0.62; 95% CI, 0.21-1.79; OR(AdvancedinflammationAdj)=0.58; 95% CI, 0.22-1.48). CONCLUSIONS Interethnic differences in nontraditional anthropometric measurements like %BF suggests their potential role in understanding interethnic differences in hepatitis C virus-related liver disease risk in males.

Combinative analysis of factors influence serum alanine aminotransferase activity in adult male population from southern China. Clin Biochem 2012; 45:1683-8. [PMID: 22975640 DOI: 10.1016/j.clinbiochem.2012.08.022] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2012] [Revised: 08/26/2012] [Accepted: 08/27/2012] [Indexed: 12/24/2022]
Abstract
OBJECTIVES Abnormal alanine aminotransferase (ALT) activity is indicative of liver disease even a burden of overall health. We assessed the factors associated with ALT activity and their internal relationships in a male population from southern China. DESIGN AND METHODS Data of physical examinations, laboratory tests, hepatic ultrasounds and standardized questionnaire were collected from 2119 males participating in a population-based survey from September 2009 to December 2009. RESULTS Nonalcoholic fatty liver disease (NAFLD) and metabolic syndrome (MetS) were associated with the elevation of ALT levels (P<0.05). Prevalence of NAFLD was correlated to MetS (r=0.991, P=0.009). The levels of abnormal metabolic syndrome components increased in proportion with the ALT elevation (P<0.01). Obesity and hyperlipidemia were associated with the ALT levels in multivariate regression analysis (P<0.01). There was no synergic effect of hepatitis B virus surface antigen (HBsAg) and MetS on the ALT levels (synergy index [SI]=0.74, 95% confidence interval [CI]: 0.71-0.80). CONCLUSION NAFLD and MetS were associated with ALT levels in a male population from southern China. Obesity and hyperlipidemia were independent MetS components contributing to elevated ALT (e-ALT). This finding might suggest necessity on justification of these confounding factors when detecting ALT levels among this population.

Abstract
Background. Hepatitis C virus (HCV) genotype 3 is known to cause steatosis (fatty liver) that is more frequent and severe than other genotypes. We previously identified sequence elements within genotype 3 HCV Core domain 3 that were sufficient for lipid accumulation. Aims. We examined various genotype 3 Core domains for lipid droplet localization and compared the lipid droplet binding regions of domain 2 with a genotype 1 isolate. Methods. We generated HCV Core domain constructs fused with green fluorescent protein and performed immunofluorescence to visualize lipid droplets. Results. Constructs containing HCV Core domain 2 are appropriately localized to lipid droplets with varying degrees of efficiency. When compared to genotype 1, there are polymorphisms within domain 2 that do not appear to alter lipid droplet localization. Conclusions. In summary, the differences in a steatosis-associated HCV Core genotype 3 isolate do not appear to involve altered lipid droplet localization.

Abstract
BACKGROUND Several single nucleotide polymorphisms (SNPs) within the interleukin 28B (IL28B) locus are associated with sustained viral response in chronic hepatitis C (HCV) patients who were treated with pegylated interferon (PEG-IFN) plus ribavirin (RBV) combination therapy. Recently, an association between γ-GTP level and IL28B genotype was identified. In this study, the relationship between IL28B genotype and liver steatosis was analyzed. METHODS One hundred fifty-three patients who underwent liver biopsy before PEG-IFN plus RBV combination therapy were enrolled. The level of liver steatosis was measured using a BIOREVO BZ-9000 microscope, and the proportion of fatty change and clear cell change were calculated using Dynamic cell count BZ-H1C software. IL28B SNP genotype (rs8099917) was determined using the Invader Assay. RESULTS Vesicular change was significantly associated with body mass index (BMI), HCV RNA titer, serum aspartate aminotransferase, γ-GTP, IL28B genotype and liver fibrosis level (P < 0.05). Clear cell change was significantly associated with serum aspartate aminotransferase, γ-GTP and IL28B genotype by univariate logistic regression analysis (P < 0.05). Under multiple logistic regression, IL28B genotype (OR(adj) = 8.158; 95% CI 2.412-27.589), liver fibrosis (OR(adj) = 2.541; 95% CI 1.040-6.207) and BMI (OR(adj) = 1.147; 95% CI 1.011-1.301) were significant independent factors for vesicular change and IL28B genotype (OR(adj) = 3.000; 95% CI 1.282-7.019) for clear cell change. CONCLUSION In this study, a new quantitative method to objectively evaluate hepatic steatosis was described. IL28B genotypes were significantly associated with both vesicular and clear cell changes of livers in chronic hepatitis C patients.

Abstract
BACKGROUND & AIMS In animal studies, expression of hepatitis B virus (HBV) proteins causes hepatic steatosis. We aimed to study the prevalence of fatty liver in people with and without HBV infection in the general population. METHODS We performed a cross-sectional population study in Hong Kong Chinese. Intrahepatic triglyceride content (IHTG) was measured by proton-magnetic resonance spectroscopy. RESULTS One thousand and thirteen subjects (91 HBV patients and 922 controls) were recruited. The median IHTG was 1.3% (0.2-33.3) in HBV patients and 2.1% (0-44.2) in controls (p <0.001). Excluding subjects with significant alcohol consumption, the prevalence of nonalcoholic fatty liver disease was 13.5% (95% confidence interval [CI] 6.4%, 20.6%) in HBV patients and 28.3% (95% CI 25.3%, 31.2%) in controls (p=0.003). The fatty liver prevalence differed in HBV patients and controls aged 40-59 years but was similar in those aged 60 years or above. After adjusting for demographic and metabolic factors, HBV infection remained an independent factor associated with lower risk of fatty liver (adjusted odds ratio 0.42; 95% CI 0.20, 0.88; p=0.022). HBV patients also had a lower prevalence of metabolic syndrome (11.0% vs. 20.2%; p=0.034), but the difference was mainly attributed to lower triglyceride levels. Among HBV patients, viral genotypes, HBV DNA level and hepatitis B e antigen status were not associated with fatty liver. CONCLUSIONS HBV infection is associated with a lower prevalence of fatty liver, hypertriglyceridemia and metabolic syndrome. Viral replication may affect lipid metabolism and this warrants further studies.

Abstract
Nonalcoholic fatty liver disease (NAFLD) includes a wide spectrum of histological conditions, extending from simple steatosis to end-stage liver failure. The aim of this study was to examine the prevalence of NAFLD and its associations in chronic hepatitis B and C patients. Methods. We included all patients diagnosed with chronic hepatitis B and C who underwent a liver biopsy between January 2010 and October 2011 (n = 104). Parameters studied included hepatitis type, anthropometric data, histologic, hepatic, metabolic and lipid assessments, presence of hypertension and viral load. Results. Hepatitis B was presented in 28.8% (n = 30) of patients, while hepatitis C was presented in 71.2% (n = 74). In addition, hepatic steatosis was present in 25% (n = 26) of the patients. Steatosis was frequently found in hepatitis C patients (31.1%; 25% n = 23), but infrequently in hepatitis B patients (10%; n = 3) (P = 0.024). It was also found that steatosis was frequently present in hepatitis C patients with intense fibrosis (52.94%) (P = 0.025). Discussion. Our results suggest that steatosis is a common feature in patients with viral chronic hepatitis, and that it plays a different role in each type of hepatitis.
