Patients often do not respond truthfully to physicians' interviews concerning alcohol. Few reports regarding the level of alcohol dependence in patients with chronic liver disease (CLD) have been presented. This study aimed to elucidate severity distribution in patients with CLD using the alcohol use disorders identification test (AUDIT).From March to June 2022, 2034 Japanese outpatients with CLD, including 415 cases associated with hepatitis C virus, 436 with hepatitis B virus, 173 with alcohol-related liver disease (ARLD), and 1010 with other factors, were interviewed using AUDIT. Clinical features related to alcohol use in these patients were then retrospectively evaluated.In all patients, an AUDIT score 8-14 (harmful use) was noted in 5.8% of hepatitis C virus, 8.9% of hepatitis B virus, 24.3% of ARLD, and 4.4% of other groups, respectively (P 0.001), while a score ≥15 (dependency) was noted in 3.4%, 3.0%, 27.7%, and 1.9%, respectively (P 0.001). When the country was divided into regions, the percentages remained similar. Comparisons between patients with and without an AUDIT score ≥8 (n = 1412), performed after exclusion of those without related data (n = 622), showed no significant differences for hepatic reserve function, while those with harmful alcohol use were significantly younger (66 vs. 70 years, P = 0.006) and had a larger percentage of men (80.4% vs. 45.1%, P 0.001).Harmful alcohol and alcohol dependency were observed in approximately 10% of patients with viral or non-viral CLD, after excluding patients with ARLD. Assessment of alcohol intake by use of the AUDIT questionnaire as well as adequate intervention should be considered necessary.

AIM Sarcopenia has a high prevalence and can be an adverse predictor in patients with chronic liver diseases (CLDs). We sought to assess the prevalence of sarcopenia and its prognostic significance in patients with CLDs at multiple centers in Japan. METHODS In this retrospective study, we collated the data of 1624 patients with CLDs (976 men). The diagnosis of sarcopenia was determined by the sarcopenia assessment criteria of the Japan Society of Hepatology. Predictors of mortality were identified using univariate and multivariate analyses. RESULTS Muscle weakness and skeletal muscle loss occurred in 33.5% and 29.3% of all subjects, respectively, while sarcopenia occurred in 13.9% of all patients. Patients with sarcopenia had a poorer prognosis among all patients, patients with hepatocellular carcinoma (HCC), and those without HCC by log-rank test. The multivariate Cox proportional hazards model identified female gender (hazard ratio [HR], 0.59; p = 0.03), alcoholic liver disease (HR, 4.25; p

AIM Management of low skeletal muscle mass (LSM) is a very important topic as LSM affects patient mortality in liver diseases. Changes in body composition are unexplored in chronic hepatitis C virus (HCV) patients, including those with liver cirrhosis, who receive direct-acting antiviral (DAA) therapy. Body composition measurements and liver function tests were carried out before and after DAA therapy. METHODS Blood examination, visceral fat area (VFA) and extremity skeletal muscle mass were measured using the multifrequency bioelectrical impedance analysis method: (i) at 24 weeks before DAA therapy; (ii) at the start of DAA therapy; (iii) at the end of DAA therapy; (iv) at 24 weeks after DAA therapy; and (v) at 48 weeks after DAA therapy. RESULTS Serum albumin (Alb) levels were significantly increased at 48 weeks post DAA therapy, especially in patients with LSM. Skeletal muscle mass index (SMI) was significantly increased after DAA therapy (at 24 weeks and 48 weeks post DAA therapy) in patients with LSM (P

Objective Non-alcoholic fatty liver disease (NAFLD) is frequently associated with obesity, dyslipidemia and type-2 diabetes mellitus. Bile acids (BAs) bind to the farnesoid X receptor (FXR) and G protein-coupled receptor 5 (TGR5), which are involved in lipid and glucose metabolism and energy expenditure. The present study aimed to determine associations between the circulating BAs and the skeletal muscle volume (SMV), and lipid and glucose metabolism in patients with NAFLD. Methods Serum BAs and metabolic parameters were measured in 55 patients with NAFLD (median age, 55 years). The changes (Δ) in serum BA (ΔBA) and metabolic parameters were determined in 17 patients (male, n=10; female, n=7) who received nutritional counseling for 12 months. Results Spearman's test revealed that the levels of 12α-hydroxysterol (12α-OH) BAs, including deoxycholic acid (DCA), were inversely correlated with the SMV of the upper and lower limbs and the total SMV. A multivariate analysis revealed that the level of DCA was correlated with a reduced total SMV, whereas non-12α-OH BAs, including chenodeoxycholic acid (CDCA), were correlated with an increased SMV of the lower limbs. Changes in CDCA were positively correlated with the ΔSMV of the lower limbs, and inversely correlated with the Δwaist-hip ratio and Δtotal cholesterol. Changes in the total non-12α-OH BA level were positively correlated with the ΔSMV of the lower limbs. Conclusion Circulating BAs were associated with SMV. The 12α-OH BAs, including DCA were associated with reduced SMV levels, whereas non-12α-OH BAs including CDCA were associated with increased SMV levels. The molecular mechanisms underlying the association between the BA levels and the SMV remain to be explored.

The aim of this study was to clarify the relationships among psychometric testing results, blood ammonia (NH3) levels, electrolyte abnormalities, and degree of inflammation, and their associations with the development of overt hepatic encephalopathy (HE) in liver cirrhosis (LC) patients. The relationships between covert HE and blood NH3, sodium (Na), and C-reactive protein (CRP) were examined in 40 LC patients. The effects of elevated NH3, hyponatremia, and elevated CRP on the development of overt HE were also investigated. The covert HE group had significantly lower serum Na levels and significantly higher serum CRP levels. During the median observation period of 11 months, 10 patients developed overt HE, and the results of multivariate analysis showed that covert HE and elevated blood NH3 were factors contributing to the development of overt HE. Electrolyte abnormalities and mild inflammation are involved in the pathogenesis of HE. Abnormal psychometric testing results and hyperammonemia are linked to subsequent development of overt HE.

Management of low skeletal muscle mass (LSM) is a very important topic as LSM affects patient mortality in liver diseases. Changes in body composition are unexplored in chronic hepatitis C virus (HCV) patients, including those with liver cirrhosis, who receive direct-acting antiviral (DAA) therapy. Body composition measurements and liver function tests were carried out before and after DAA therapy.Blood examination, visceral fat area (VFA) and extremity skeletal muscle mass were measured using the multifrequency bioelectrical impedance analysis method: (i) at 24 weeks before DAA therapy; (ii) at the start of DAA therapy; (iii) at the end of DAA therapy; (iv) at 24 weeks after DAA therapy; and (v) at 48 weeks after DAA therapy.Serum albumin (Alb) levels were significantly increased at 48 weeks post DAA therapy, especially in patients with LSM. Skeletal muscle mass index (SMI) was significantly increased after DAA therapy (at 24 weeks and 48 weeks post DAA therapy) in patients with LSM (P 0.05). An increase in SMI was associated with an increase in body weight or a decrease in VFA.We continuously measured body composition in HCV-infected patients who received DAA therapy and found that skeletal muscle mass was significantly increased, associated with an elevation of serum Alb levels and/or body weight or reduction in VFA, but only in patients who presented with LSM before DAA therapy.

Objective Although the prognosis is known to be poor in cirrhosis patients associated with sarcopenia, the relationships among skeletal muscle, visceral fat, and the liver have not yet been thoroughly investigated. Therefore, the prognosis and its associations with body composition and the severity of liver disease were examined in patients with cirrhosis. Methods The skeletal muscle mass and visceral fat area were measured in 161 patients with cirrhosis, the effects of body composition on the prognosis were analyzed, and any factors that contribute to changes in body composition were assessed. Results During the mean observation period of 1,005 days, 73 patients died. Patients with sarcopenia or sarcopenic obesity had a poor prognosis, and this difference was pronounced in the subset of patients classified as Child-Pugh class A. A decreased skeletal muscle mass was strongly correlated with decreased serum albumin levels. Sarcopenia is a common feature of advanced cirrhosis, and transitions were observed from normal body composition to sarcopenia and from obese to sarcopenic obesity. Conclusion The body composition is a prognostic factor for cirrhosis, and a better body composition may be advantageous for obtaining a long-term survival in patients with cirrhosis.

Aim: To clarify the impact of visceral fat on chronic liver diseases such as non-alcoholic fatty liver disease (NAFLD) and hepatitis C, we investigated the effects of lifestyle modifications on the amount of visceral fat, liver biochemistry and serum ferritin levels in patients with liver disease. Methods: Eighty-two patients (NAFLD, n = 37; hepatitis C, n = 45) were advised to adopt lifestyle modifications, including dietary changes and exercise, and these were maintained for 6 months. Bodyweight, percentage of body fat, visceral fat area (VFA) and serum alanine aminotransferase (ALT) and ferritin were measured before and after intervention. Results: In NAFLD, the mean VFA of 134.5 cm2 was significantly reduced to 125.3 cm2 after 6 months (P

Ninety seven patients with chronic hepatitis C (CHC) and 72 with non-alcoholic fatty liver disease (NAFLD) were enrolled. Increased visceral fat area (VFA) was associated with high values of HbA1c. The variables associated with a high risk of new-onset diabetes had a VFA>101 cm(2) in CHC, but not in NAFLD.

Objectives:Very few reports thus far have clinically elucidated the advantages of a nutrition support team (NST) in the!eld of liver diseases. The present study retrospectively analyzed whether nutrition therapy for liver cirrhosis (LC), performed by a multidisciplinary team that includes registered dieticians, improves survival rates. Methods:In study 1, we compared survival rates between two groups of patients with LC to elucidate the effects of nutrition management by registered dieticians. The!rst group was comprised of 101 patients that received no dietary counseling from a dietician, and the second group was comprised of 133 patients that received nutritional counseling following nutrition assessment. In study 2, we split the patients who received nutritional counseling in study 1 into two groups and compared their survival rates with the objective of investigating the effects of a multidisciplinary team approach on survival rate. The!rst group was comprised of 51 patients that, in addition to regular nutritional counseling given by a dietician, regularly attended courses on liver disease given every 3 to 6 mo. The second group was comprised of 82 patients that did not attend the liver-disease courses. Results:During study 1, 34 patients in the!rst group and 20 patients in the second group died, representing a signi!cant difference (P

To clarify the impact of visceral fat on chronic liver diseases such as non-alcoholic fatty liver disease (NAFLD) and hepatitis C, we investigated the effects of lifestyle modifications on the amount of visceral fat, liver biochemistry and serum ferritin levels in patients with liver disease. Eighty-two patients (NAFLD, n = 37; hepatitis C, n = 45) were advised to adopt lifestyle modifications, including dietary changes and exercise, and these were maintained for 6 months. Bodyweight, percentage of body fat, visceral fat area (VFA) and serum alanine aminotransferase (ALT) and ferritin were measured before and after intervention. In NAFLD, the mean VFA of 134.5 cm(2) was significantly reduced to 125.3 cm(2) after 6 months (P 0.001). ALT levels improved significantly between the values measured before and after intervention (P = 0.039). The VFA prior to intervention was 100 cm(2) in hepatitis C patients and it was reduced significantly after 6 months to 95.6 cm(2) (P 0.001). ALT levels also improved significantly in the hepatitis C patients (P 0.001). The serum ferritin levels also reduced in these patients. Improvements in serum ALT and ferritin levels correlated with the amount of visceral fat reduction in both groups (P = 0.046, P = 0.008, respectively). These findings demonstrate that restriction of calorie and iron intake results in reduction of visceral fat, liver enzymes and ferritin in patients with chronic liver disease. Visceral fat may be a central target for future interventions, not only in NAFLD but also in hepatitis C.

Aims: Ascites, which often complicates liver cirrhosis, is reported to be a factor that worsens the outcome. The aims of this study were to quantify body water compartment changes in cirrhotic patients, with and without ascites, and to elucidate the value of body water analysis for predicting the development of ascites. Methods: A total of 109 cirrhotic patients, with and without ascites, and 65 controls were studied. Intra- and extracellular water (ECW) in the whole body and in the arm, leg and trunk were measured using the recently developed 8-electrodes multiple-frequency bioelectrical impedance analyzer. Furthermore, patients without ascites were followed to an episode of ascites or death. Results: Patients with liver cirrhosis had significantly higher ECW ratios than controls. ECW ratios were increased in cirrhotic patients with moderate and severe disease. The ECW ratio of the trunk showed highly significant changes in cirrhotic patients with ascites. The ECW ratio correlated with age, serum albumin, and prothrombin time. A relative expansion of ECW and low albumin were predictive of further episodes of ascites (log-rank 6.94, P

Retinol-binding protein 4 (RBP4) is a recently identified adipokine that is elevated in the blood in several insulin-resistant states. We investigated the association between plasma RBP4 and histological and biochemical characteristics of chronic hepatitis C (CHC), as well as changes in RBP4 levels following interferon therapy. Eighty-one patients with CHC infected with genotype 1 received treatment with peginterferon plus ribavirin. Histological data were available for 41 out of 81 patients before treatment, and the degree of fibrosis, inflammation and steatosis was assessed. Plasma levels of RBP4 were determined in serial samples (before, at the end of treatment, and at 6 months post-treatment). RBP4 levels were lower in CHC patients than in control subjects (34.6 +/- 12.3 microg/mL vs 46.2 +/- 10.5 microg/mL; P

Aim: This study was conducted to determine the clinical relevance of hepcidin, a recently identified key iron regulatory hormone, in patients with chronic hepatitis C virus (C-HCV). Methods: Serum hepcidin levels were measured in 9 C-HCV patients by surface-enhanced laser desorption/ionization time of flight mass spectrometry (SELDI-TOF-MS), and compared to those of healthy controls. Sequential changes of hepcidin were also investigated during phlebotomy. Results: Serum hepcidin and ferritin were significantly higher in C-HCV than in controls (P = 0.0002), these two variables were strongly related to each other (r = 0.658; P

Long-term supplementation with branched-chain amino acids (BCAA) is associated with prolonged survival and decreased frequency of development of hepatocellular carcinoma (HCC) in patients with liver cirrhosis. However, the pharmaceutical mechanism underlying this association is still unclear. We investigated whether continuous BCAA supplementation increases survival rate of rats exposed to a fibrogenic agent and influences the iron accumulation, oxidative stress, fibrosis, and gluconeogenesis in the liver. Further, the effects of BCAA on gluconeogenesis in cultured cells were also investigated. A significant improvement in cumulative survival was observed in BCAA-supplemented rats with advanced cirrhosis compared to untreated rats with cirrhosis (P
