    Objective: To describe the mortality pattern pertaining to chronic liver disease (CLD) in Northern Pakistan. Results: There were a total of 8529 admissions in twelve months period from August 2001 to July 2002. There were 283 (3.31%) total deaths. Out of these, 160 deaths were pertaining to medical causes. Out of these medical cases, 33 (20.6%) patients had died of chronic liver disease. Other major causes of death were cerebro-vascular accident (18.7%), malignancy (18.1%) and acute myocardial infarction (10.6%). Out of 33 patients of CLD, 12 (36%) presented with acute gastrointestinal (Gl) bleeding, 9(27%) presented with Ascites and 6(18%) presented with altered mental status due to hepatic encephalopathy. Rest of them had jaundice and fever as their initial presentation. Out of these 33 patients with CLD, 23 (70%) had hepatitis C virus (HCV) as cause of their liver disease, 4 (12%) had hepatitis B virus (HBV) infection, 3(9%) had both hepatitis B and hepatitis C virus infections and 3 (9%) had no known cause of their chronic liver disease. Conclusion: Chronic liver disease is a major cause of mortality in this part of Pakistan at a tertiary care hospital. HCV infection is the main cause of chronic liver disease followed by either HBV or a combination of these viruses. Major manifestations of CLD have been gastrointestinal bleeding, hepatic failure and portal hypertension.(author)

    Full Text Available Patients with chronic liver disease often suffer from unspecific symptoms and report severe impairment in the quality of life. The underlying mechanisms are multifactorial and include disease-specific but also liver related causes. The current analysis evaluated the association of hepatocellular apoptosis in non-viral chronic liver disease and health-related quality of life (HRQL. Furthermore we examined factors, which influence patient's physical and mental well-being.A total of 150 patients with non-infectious chronic liver disease were included between January 2014 and June 2015. The German version of the Chronic Liver Disease Questionnaire (CLDQ-D, a liver disease specific instrument to assess HRQL, was employed. Hepatocellular apoptosis was determined by measuring Cytokeratin 18 (CK18, M30 Apoptosense ELISA.Female gender (5.24 vs. 5.54, p = 0.04, diabetes mellitus type II (4.75 vs. 5.46, p<0.001 and daily drug intake (5.24 vs. 6.01, p = 0.003 were associated with a significant impairment in HRQL. HRQL was not significantly different between the examined liver diseases. Levels of CK18 were the highest in patients with NASH compared to all other disease entities (p<0.001. Interestingly, CK18 exhibited significant correlations with obesity (p<0.001 and hyperlipidemia (p<0.001. In patients with cirrhosis levels of CK18 correlated with the MELD score (r = 0.18, p = 0.03 and were significantly higher compared to patients without existing cirrhosis (265.5 U/l vs. 186.9U/l, p = 0.047. Additionally, CK18 showed a significant correlation with the presence and the degree of hepatic fibrosis (p = 0.003 and inflammation (p<0.001 in liver histology. Finally, there was a small negative association between CLDQ and CK18 (r = -0.16, p = 0.048.Different parameters are influencing HRQL and CK18 levels in chronic non-viral liver disease and the amount of hepatocellular apoptosis correlates with the impairment in HRQL in chronic non-viral liver diseases.

    Full Text Available Liver stiffness measurement (LSM by transient elastography (TE, FibroScan is a validated method for noninvasively staging liver fibrosis. Most hepatic complications occur in patients with advanced fibrosis. Our objective was to determine the ability of LSM by TE to predict hepatic complications and mortality in a large cohort of patients with chronic liver disease.In consecutive adults who underwent LSM by TE between July 2008 and June 2011, we used Cox regression to determine the independent association between liver stiffness and death or hepatic complications (decompensation, hepatocellular carcinoma, and liver transplantation. The performance of LSM to predict complications was determined using the c-statistic.Among 2,052 patients (median age 51 years, 65% with hepatitis B or C, 87 patients (4.2% died or developed a hepatic complication during a median follow-up period of 15.6 months (interquartile range, 11.0-23.5 months. Patients with complications had higher median liver stiffness than those without complications (13.5 vs. 6.0 kPa; P<0.00005. The 2-year incidence rates of death or hepatic complications were 2.6%, 9%, 19%, and 34% in patients with liver stiffness <10, 10-19.9, 20-39.9, and ≥40 kPa, respectively (P<0.00005. After adjustment for potential confounders, liver stiffness by TE was an independent predictor of complications (hazard ratio [HR] 1.05 per kPa; 95% confidence interval [CI] 1.03-1.06. The c-statistic of liver-stiffness for predicting complications was 0.80 (95% CI 0.75-0.85. A liver stiffness below 20 kPa effectively excluded complications (specificity 93%, negative predictive value 97%; however, the positive predictive value of higher results was sub-optimal (20%.Liver stiffness by TE accurately predicts the risk of death or hepatic complications in patients with chronic liver disease. TE may facilitate the estimation of prognosis and guide management of these patients.

    Full Text Available Liver stiffness measurement (LSM using transient elastography (FibroScan® can assess liver fibrosis noninvasively. This study investigated whether LSM can predict the development of liver-related events (LREs in chronic hepatitis B (CHB patients showing histologically advanced liver fibrosis.Between March 2006 and April 2010, 128 CHB patients with who underwent LSM and liver biopsy (LB before starting nucleot(side analogues and showed histologically advanced fibrosis (≥F3 with a high viral loads [HBV DNA ≥2,000 IU/mL] were enrolled. All patients were followed regularly to detect LRE development, including hepatic decompensation (variceal bleeding, ascites, hepatic encephalopathy, spontaneous bacterial peritonitis, hepatorenal syndrome and hepatocellular carcinoma (HCC.The mean age of the patient (72 men, 56 women was 52.2 years. During the median follow-up period [median 27.8 (12.6-61.6 months], LREs developed in 19 (14.8% patients (five with hepatic decompensation, 13 with HCC, one with both. Together with age, multivariate analysis identified LSM as an independent predictor of LRE development [P19 kPa were at significantly greater risk than those with LSM≤19 kPa for LRE development (HR, 7.176; 95% CI, 2.257-22.812; P = 0.001.LSM can be a useful predictor of LRE development in CHB patients showing histologically advanced liver fibrosis.

    Full Text Available Liver biopsy is indispensable because liver stiffness measurement alone cannot provide information on intrahepatic inflammation. However, the presence of fibrosis highly correlates with inflammation. We constructed a noninvasive model to determine significant inflammation in chronic hepatitis B patients by using liver stiffness measurement and serum markers.The training set included chronic hepatitis B patients (n = 327, and the validation set included 106 patients; liver biopsies were performed, liver histology was scored, and serum markers were investigated. All patients underwent liver stiffness measurement.An inflammation activity scoring system for significant inflammation was constructed. In the training set, the area under the curve, sensitivity, and specificity of the fibrosis-based activity score were 0.964, 91.9%, and 90.8% in the HBeAg(+ patients and 0.978, 85.0%, and 94.0% in the HBeAg(- patients, respectively. In the validation set, the area under the curve, sensitivity, and specificity of the fibrosis-based activity score were 0.971, 90.5%, and 92.5% in the HBeAg(+ patients and 0.977, 95.2%, and 95.8% in the HBeAg(- patients. The liver stiffness measurement-based activity score was comparable to that of the fibrosis-based activity score in both HBeAg(+ and HBeAg(- patients for recognizing significant inflammation (G ≥3.Significant inflammation can be accurately predicted by this novel method. The liver stiffness measurement-based scoring system can be used without the aid of computers and provides a noninvasive alternative for the prediction of chronic hepatitis B-related significant inflammation.

    We aim to study the impact of the baby boomer (BB) generation, a birth-specific cohort (born 1945-1965) on hepatocellular carcinoma (HCC)-related liver transplantation (LT) in patients with chronic hepatitis C virus (HCV), alcoholic liver disease (ALD), and non-alcoholic steatohepatitis (NASH). We performed a retrospective analysis using the United Network for Organ Sharing (UNOS)/Organ Procurement Transplant Network (OPTN) database from 2003 to 2014 to compare HCC-related liver transplant surgery trends between two cohorts-the BB and non-BB-with a secondary diagnosis of HCV, ALD, or NASH. From 2003-2014, there were a total of 8313 liver transplant recipients for the indication of HCC secondary to HCV, ALD, or NASH. Of the total, 6658 (80.1%) HCC-related liver transplant recipients were BB. The number of liver transplant surgeries for the indication of HCC increased significantly in NASH (+1327%), HCV (+382%), and ALD (+286%) during the study period. The proportion of BB who underwent LT for HCC was the highest in HCV (84.7%), followed by NASH (70.3%) and ALD (64.7%). The recommendations for birth-cohort specific HCV screening stemmed from a greater understanding of the high prevalence of chronic HCV and HCV-related HCC within BB. The rising number of HCC-related LT among BB with ALD and NASH suggests the need for increased awareness and improved preventative screening/surveillance measures within NASH and ALD cohorts as well.

    Full Text Available ObjectiveTo investigate the prognostic factors for patients with hepatitis B virus-related acute-on-chronic liver failure, and to provide a basis for clinical diagnosis and treatment. MethodsA total of 172 patients with hepatitis B virus (HBV-related acute-on-chronic liver failure who were admitted to The First Hospital of Jilin University from January 1, 2006 to January 1, 2016 and had complete medical records and follow-up data were enrolled, and a retrospective analysis was performed for their clinical data and laboratory markers to determine prognostic factors. The independent-samples t test was used for comparison of continuous data between groups, the chi-square test was used for comparison of categorical data between groups, and a multivariate logistic regression analysis was performed for the indices determined to be statistically significant by the univariate analysis to screen out independent risk factors for the prognosis of patients with HBV-related acute-on-chronic liver failure. ResultsThe multivariate logistic regression analysis was performed for the indices determined to be statistically significant by the univariate analysis, and the results showed that the prognostic factors were total bilirubin (TBil, prothrombin time activity (PTA, Na+, total cholesterol (TC, Child-Turcotte-Pugh (CTP score, age ≥50 years, the presence of liver cirrhosis, bilirubin-enzyme separation, and complications. The multivariate regression analysis was performed for the complications determined to affect prognosis by the univariate analysis, and the results showed that the complications as risk factors were hepatic encephalopathy, hepatorenal syndrome, and infection. ConclusionTBil, PTA, Na+, TC, CTP score, age ≥50 years, the presence of liver cirrhosis, bilirubin-enzyme separation, and complications are independent risk factors for the prognosis of patients with HBV-related acute-on-chronic liver failure.

    Full Text Available ObjectiveTo construct a hybrid bioartificial liver support system and to investigate its safety and efficacy in patients with hepatitis B virus (HBV-related acute-on-chronic liver failure (ACLF. MethodsA hollow fiber bioreactor was constructed using cultured HepG2 cells transfected with human augmenter of liver regeneration gene. Patients with HBV-related ACLF who were hospitalized in our hospital from May 2009 to August 2011 were randomly divided into treatment group (n=10 and control group (n=10. The treatment group was treated using the hybrid bioartificial liver support system, while the control group was treated with conventional plasma exchange. Comparison of means between the two groups was made by independent-samples t test, and comparison of variables before and after treatment was made by paired t test. ResultsOf the 10 patients in treatment group, 7 had improvement in clinical symptoms and were discharged, 1 died of hepatic encephalopathy, 1 died of hepatorenal syndrome, and 1 died of liver failure after discharge. Of the 10 patients in control group, 5 survived, 1 underwent liver transplantation, and 4 died of liver failure. Before treatment, the treatment group and control group had model for end-stage liver disease (MELD scores of 24.26±2.54 and 24.71±2.79, respectively, without significant difference between the two groups (t=1.971, P=0.064. The treatment group had MELD scores of 21.71±2.92, 22.10±4.46, and 19.90±5.43 after 3 days, 1 week, and 4 weeks, respectively, of treatment. At the end of one-year follow-up, the mean serum alpha-fetoprotein levels were 14.24 ng/ml in treatment group and 11.32 ng/ml in control group, and no space-occupying lesions in the liver were found through abdominal ultrasound. ConclusionThe constructed hybrid bioartificial liver support system is effective and safe in the treatment of HBV-related ACLF.

    In 21 patients with chronic liver disease, the ratio of liver to muscle signal intensity on T 1 -weighted images was negatively correlated with the progression of hepatic fibrosis defined according to findings by laparoscopy and liver biopsy, and differentiated six patients with early chronic hepatitis from eight with liver cirrhosis. On T 2 -weighted images, the number of low intensity nodules comparable in size to regenerating nodules surrounded by connective tissues showed a positive correlation with stage. When hepatic fibrosis with no necrosis or fat infiltration was induced in rats, T 2 values were positively correlated with hepatic hydroxyproline content, though there was no such correlation for T 1 values. These results suggest that MR imaging may be useful for determining the progression of hepatic fibrosis in chronic liver disease. T 2 values may directly reflect hepatic fibrosis. (author)

    Full Text Available Although HBV is a non-cytopathic virus, alteration of viral genome may also alter host immunity and may play a part in the pathogenesis LC and HCC. During the last decade, various studies have shown that mutations in the HBV genome may play a role in HCC pathogenesis. Here, we have analyzed HBV genome from patients with asymptomatic HBV carrier [ASC], chronic hepatitis B (CHB, cirrhosis of liver (LC, and hepatocellular carcinoma (HCC of Bangladeshi origin. A total of 225 patients tested positive for HBV with different stages of chronic HBV infection were enrolled in this study. The extent of liver damages were assayed by estimating serum levels of alanine aminotransferase (ALT, serum bilirubin and finally by abdominal ultrasonography and/or fine needle aspiration cytology. Wherever required, cancer marker like alpha fetoprotein (AFP was assessed. HBV genotype was evaluated by immunoassays and sequenced. A total of 25 patients were ASC, 135 were CHB and 65 were LC and HCC. Among ASC patients, 5, 7 and 13 belonged to HBV genotype A, C, and D, respectively. On the other hand, HBV genotype C was most prevalent in CHB patients (about 42%, followed by HBV genotype D (36%. About 69% patients with LC and HCC also had genotype C. Full genomic analysis of sera of patients with progressive liver damages (LC and HCC revealed mutations at HBeAg promoter regions in more than 80% patients. However, mutations in this region were mostly unseen in ASC and patients with less progressive liver diseases. HBV genotype was found quite different in Bangladeshi HBV patients which seem a mixture of Indian and Asia-Pacific region. This study also reveals that HBeAg promoter region mutation may have role in development of HBV related LC and HCC.

    Full Text Available With prevalence of 10–20% in adults in developed countries, gallstone disease (GSD is one of the most prevalent and costly gastrointestinal tract disorders in the world. In addition to gallstone disease, chronic liver disease (CLD is also an important global public health problem. The reported frequency of gallstone in chronic liver disease tends to be higher. The prevalence of gallstone disease might be related to age, gender, etiology, and severity of liver disease in patients with chronic liver disease. In this review, the aim was to identify the epidemiology, mechanisms, and treatment strategies of gallstone disease in chronic liver disease patients.

    Patient-reported outcomes like health-related quality of life (HRQL) have become increasingly important for full assessment of patients with chronic liver diseases (CLD). To explore the relative impact of different types of liver disease on HRQL as well as predictors of HRQL domains in CLD. Our HRQL databases with Short-Form 36 (SF-36) data were used. Scores for each of SF-36 scales (PF - physical functioning, RP - role functioning, BP - bodily pain, GH - general health, VT - vitality, SF - social functioning, RE - role emotional and MH - mental health, MCS - mental component score, PCS - physical component score) were compared between different types of CLD as well as other variables. Complete data were available for 1103 CLD patients. Demographic and clinical data included: age 54.2 +/- 12.0 years, 40% female, 761 (69%) with cirrhosis. Analysis revealed that age correlated significantly (P < 0.05) with worsening HRQL on every scale of the SF-36. Female patients had more HRQL impairments in PF, RP, BP, GH, VT and MH scales of SF-36 (Delta scale score: 6.6-10.7, P < 0.05). Furthermore, cirrhotic patients had more impairment of HRQL in every scale of SF-36 (Delta scale score: 6.6-43.0, P < 0.05). In terms of diagnostic groups, non-alcoholic fatty liver disease patients showed more impairment of HRQL. Analysis of this large CLD cohort suggests that a number of important clinicodemographic factors are associated with HRQL impairment. These findings contribute to the full understanding of the total impact of CLD on patients' health.

    Objective: Patients with cirrhosis due to hepatitis C (HC) have an increased prevalence of diabetes mellitus. The pathogenic mechanism by which HC predisposes to DM is not clear. The objective of this study was to determine the insulin and C-peptide response to 75 gram oral glucose load and measure anti phospholipid antibody levels in patients with chronic liver disease due to HC. Design: a prospective study. Place and duration of study: This study was conducted at the department of medicine, Jinnah postgraduate medical centre over period of three months. Subjects and methods: An analytical case control study was carried out on 37 patients (m-18,f=19); none of these patients had received interferon. They were divided into four groups: (a) HC cirrhosis with DM (n=9 ), (b) HC cirrhosis without DM (n=11), (c) hepatitis B (HB) cirrhosis without DM (n=7), (d) chronic hepatitis C without DM (n=10). Group C and D were taken as controls. Fasting blood samples were taken and repeated after 2 hours of 75 gram oral glucose load (2 h PG). Result: mean ages of group A,B,C and D were (yr +- SD) 51.3 +- 7.6,48.9 +- 2.4, 33.7 +-10.8 and 31.7 +- 8.8 respectively. There was no statistically significant difference in the age, Pugh score and body mass index of HC cirrhotic patients with and without DM. Patients of group A had higher fasting and 2 h PG glucose levels (P=0.003 and 0.000) and higher fasting insulin level (p=0.045). However, increments in insulin and c peptide levels 2 h PG were much less (p=0.048 and 0.003). HB cirrhotics without diabetes (group C behaved just like HC cirrhotic without diabetes (group B). Patients of group D had normal glucose tolerance and insulin and C peptide levels. All four groups had normal anti phospholipid antibody levels. Conclusion: Patients with cirrhosis due to HC nd HB show evidence of glucose intolerance in spite of hyperinsulinaemia probably due to insulin resistance. HC cirrhotics with diabetes have fasting hyperglycemia in spite of

    To evaluate the liver parenchyma according to the echo patterns of CSS (compound spatial sonography), and to correlate them with the extent of hepatic fibrosis and the serum aminotransferase level. The CSS images were classified into the following three echo patterns: type I, a normal looking echo: type II, hyperechoic or hypoechoic nodules scattered in a normal-looking echo: type III, a severely heterogeneous echogenic or hypoechoic honeycomb-like echo. The CSS findings were correlated with the histopathology findings in 63 patients with HBV. The serum aminotransferase levels and the occurrence of acute exacerbation in 168 patients with HBV, with and without a progressed parenchymal echo pattern, and who were followed up more than 1-year period, were compared. The interobserver agreement between the two radiologists for assessing the parenchymal echo pattern was scored. The correlation between the CSS pattern and hepatic fibrosis was statistically significant (correlation coefficient = 0.58, p < 0.05). The baseline serum aminotransferase level was not significantly different between the patients with and without a progressed parenchymal echo pattern. However, the rate of acute exacerbation was higher in patients with a progressed parenchymal echo pattern (p < 0.05). The interobserver agreement was good (k statistic = 0.63, 0.78). The liver parenchymal pattern based on the 5-12 MHz CSS is a useful and objective tool for diagnosing and monitoring HBV related chronic liver disease

    Cirrhotic patients are known to have abnormally high signal principally in the globus pallidus on non-contrast T1-weighted MRI. The purpose of this study was to relate MR changes to clinical and pathological features of chronic liver disease. We confirmed abnormally high signal in the globus pallidus on T1-weighted images in 25 of 28 patients with chronic liver disease, showing that it also occurs in patients who have not yet progressed to cirrhosis. Changes were seen in patients both with and without clinical portosystemic shunting. This abnormality is not responsible for hepatic encephalopathy. Cholestatic disease was more likely to produce marked changes than non-cholestatic disease. No statistically significant correlation was demonstrated between the severity of liver disease and the degree of MR abnormality. However, marked improvement in MR appearances was seen after successful liver transplantation. (orig.). With 3 figs., 4 tabs.

    The progression of chronic liver disease differs by etiology. The aim of this study was to elucidate the difference in disease progression between chronic hepatitis C (CHC) and nonalcoholic fatty liver disease (NAFLD) by means of fibrosis markers, liver function, and hepatic tissue blood flow (TBF). Xenon computed tomography (Xe-CT) was performed in 139 patients with NAFLD and 152 patients with CHC (including liver cirrhosis (LC)). The cutoff values for fibrosis markers were compared between NAFLD and CHC, and correlations between hepatic TBF and liver function tests were examined at each fibrosis stage. The cutoff values for detection of the advanced fibrosis stage were lower in NAFLD than in CHC. Although portal venous TBF (PVTBF) correlated with liver function tests, PVTBF in initial LC caused by nonalcoholic steatohepatitis (NASH-LC) was significantly lower than that in hepatitis C virus (C-LC) (p = 0.014). Conversely, the liver function tests in NASH-LC were higher than those in C-LC (p blood flow occurred during the earliest stage of hepatic fibrosis in patients with NAFLD; therefore, patients with NAFLD need to be followed carefully.

    Heavy alcohol use has been hypothesized to accelerate disease progression to end-stage liver disease in patients with hepatitis C virus (HCV) infection. In this study, we estimated the relative influences of heavy alcohol use and HCV in decompensated chronic liver disease (CLD). Retrospectively, 904 patients with cirrhotic disease admitted to our hospitals during January 2010-December 2012 were identified based on ICD9 codes. A thorough chart review captured information on demographics, viral hepatitis status, alcohol use and progression of liver disease (i.e. decompensation). Decompensation was defined as the presence of ascites due to portal hypertension, bleeding esophageal varices, hepatic encephalopathy or hepatorenal syndrome. Heavy alcohol use was defined as a chart entry of greater than six daily units of alcohol or its equivalent. 347 patients were included based on our selection criteria of documented heavy alcohol use (n = 215; 62.0%), hepatitis titers (HCV: n = 182; 52.5%) and radiological evidence of CLD with or without decompensation (decompensation: n = 225; 64.8%). Independent of HCV infection, heavy alcohol use significantly increased the risk of decompensation (OR = 1.75, 95% CI 1.11-2.75, p < 0.02) relative to no heavy alcohol use. No significance was seen with age, sex, race, HIV, viral hepatitis and moderate alcohol use for risk for decompensation. Additionally, dose-relationship regression analysis revealed that heavy, but not moderate alcohol use, resulted in a three-fold increase (p = 0.013) in the risk of decompensation relative to abstinence. While both heavy alcohol use and HCV infection are associated with risk of developing CLD, our data suggest that heavy, but not moderate, alcohol consumption is associated with a greater risk for hepatic decompensation in patients with cirrhosis than does HCV infection.

    A total of 350 million individuals are affected by chronic hepatitis B virus infection world-wide. Historically, liver biopsy has been instrumental in adequately assessing patients with chronic liver disease. A number of non-invasive models have been studied world-wide. The aim of this study is to assess the utility of non-invasive mathematical models of liver fibrosis in chronic hepatitis B (CHB). Indian patients in a resource limited setting using routinely performed non-invasive laboratory investigations. A cross-sectional study carried out at a tertiary care center. A total of 52 consecutive chronic liver disease patients who underwent percutaneous liver biopsy and 25 healthy controls were enrolled in the study. Routine laboratory investigations included serum aspartate aminotransferase (AST), Alanine aminotransferase (ALT), Gama glutamyl transpeptidase (GGT), total bilirubin, total cholesterol, prothrombin time and platelet count. Three non-invasive models for namely aspartate aminotransferase to platelet ratio index (APRI), Fibrosis 4 (FIB-4) and Forn's index were calculated. Outcomes were compared for the assessment of best predictor of fibrosis by calculating the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of each index. Medcalc online software and by Microsoft Excel Worksheet. Chi-square test was used for significance. P value value of all 3 indices were significantly higher in patients group as compare with the controls (P model for excluding significant liver fibrosis while FIB-4 with a PPV of 61% showed fair correlation with significant fibrosis. Thus, these two non-invasive models for predicting of liver fibrosis, namely APRI and FIB-4, can be utilized in combination as screening tools in monitoring of CHB patients, especially in resource limiting settings.

    Hepatocellular carcinoma (HCC) is the second most common malignancy in Egypt. Data mining is a method of predictive analysis which can explore tremendous volumes of information to discover hidden patterns and relationships. Our aim here was to develop a non-invasive algorithm for prediction of HCC. Such an algorithm should be economical, reliable, easy to apply and acceptable by domain experts. This cross-sectional study enrolled 315 patients with hepatitis C virus (HCV) related chronic liver disease (CLD); 135 HCC, 116 cirrhotic patients without HCC and 64 patients with chronic hepatitis C. Using data mining analysis, we constructed a decision tree learning algorithm to predict HCC. The decision tree algorithm was able to predict HCC with recall (sensitivity) of 83.5% and precession (specificity) of 83.3% using only routine data. The correctly classified instances were 259 (82.2%), and the incorrectly classified instances were 56 (17.8%). Out of 29 attributes, serum alpha fetoprotein (AFP), with an optimal cutoff value of ≥50.3 ng/ml was selected as the best predictor of HCC. To a lesser extent, male sex, presence of cirrhosis, AST>64U/L, and ascites were variables associated with HCC. Data mining analysis allows discovery of hidden patterns and enables the development of models to predict HCC, utilizing routine data as an alternative to CT and liver biopsy. This study has highlighted a new cutoff for AFP (≥50.3 ng/ml). Presence of a score of >2 risk variables (out of 5) can successfully predict HCC with a sensitivity of 96% and specificity of 82%.

    Chronic Liver Disease (CLD) has been shown to have an adverse impact on bone health. Hepatitis-B related CLD and its treatment with tenofovir may have additional effects on skeleton. To study the impact of HBV related CLD and its treatment with Tenofovir on bone health in Indian subjects. This cross sectional study included men (18-60 years) and comprised of three groups: Group-1 was treatment naïve HBV related CLD ( n  = 79), Group-2 those with HBV related CLD on tenofovir for at least 1 year ( n  = 136), Group-3 age, sex and Body Mass Index (BMI) matched healthy controls ( n  = 58). Bone biochemistry and Bone Mineral Density (BMD) at spine, Femoral Neck (FN) and forearm were studied. Independent t -test or ANOVA was used to compare the means of continuous variables and chi-square test for categorical variables. Multiple logistic regression was used to assess the factors causing Low Bone Mass (LBM) at FN. A significantly greater proportion ( P  CLD (group 1 and group 2) had vitamin D deficiency (CLD than controls. The prevalence of LBM was higher in group 1 at the spine (31%) and forearm (18.4%) when compared to controls (8.1% and 7.8% respectively) ( P  10,000 IU/ml) emerged as significant risk factors for LBM at FN. The impact of hepatitis-B related CLD as well as its treatment on bone health is significant. Bone health need to be periodically evaluated in these subjects especially in older men who are lean and have a higher viral load.

    The pathogenetic mechanisms of anemia in patients with chronic liver disease were observed. Seventeen patients with moderate to advanced hepatic diseases were studied by various methods. Only patients without previous blood loss were included : 14 had cirrhosis, 2 had active chronic hepatitis, and one had inferior vena cava obstruction with associated liver cirrhosis. The followings were the results: 1. The anemia based on red blood cell count, Hb., and Ht. was found in 76.5-78.6% of the patients. 2. Red cell indices indicated that normo-macrocytic and normochromic anemia was present is the majority of the patients. 3. No evidence of megaloblastic anemia was found on the basis of the morphological examinations. 4. Serum iron, TIBC, % saturation and iron content in the bone marrow indicated that iron deficiency anemia was present in about half of the patients. 5. In the view of the erythrocyte dynamics, primary increase in the red cell destruction was ascribed to the cause of the anemia. 6. Decrease in the red cell survival time was not correlated with MCV, % saturation and S.L. ratio. Also, hemoglobin level was not correlated with MCV, % saturation and T{sub 50} Cr. Therefore, multiple causes may be involved in the pathogenesis of the anemia. 7. Anemia as determined by the red cell volume was found in only 60% of the patients. It may be possible that hemodilutional anemia is present.

    Acute-on-chronic liver failure (ACLF) is the most common type of liver failure and associated with grave consequences. Systemic inflammation has been linked to its pathogenesis and outcome, but the identifiable triggers are absent. Recently, extracellular histones, especially H4, have been recognized as important mediators of cell damage in various inflammatory conditions. This study aimed to investigate whether extracellular histones have clinical implications in patients with hepatitis B virus (HBV)-related ACLF. One hundred and twelve patients with HBV-related ACLF, 90 patients with chronic hepatitis B, 88 patients with HBV-related liver cirrhosis and 40 healthy volunteers were entered into this study. Plasma histone H4 levels, cytokine profile and clinical data were obtained. Besides, patient's sera were incubated overnight with human L02 hepatocytes or monocytic U937 cells in the presence or absence of antihistone H4 antibody, and cellular damage and cytokine production were evaluated. We found that plasma histone H4 levels were greatly increased in patients with ACLF as compared with chronic hepatitis B, liver cirrhosis and healthy control subjects and were significantly associated with disease severity, systemic inflammation and outcome. Notably, ACLF patients' sera incubation decreased cultured L02 cell integrity and induced profound cytokine production in the supernatant of U937 cells. Antihistone H4 antibody treatment abrogated these adverse effects, thus confirming a cause-effect relationship between extracellular histones and organ injury/dysfunction. The data support the hypothesis that the increased extracellular histone levels in ACLF patients may aggravate disease severity by inducing cellular injury and systemic inflammation. Histone-targeted therapies may have potentially interventional value in clinical practice. © 2016 John Wiley & Sons Ltd.

    Full Text Available There is increasing interest in the identification of factors associated with liver disease progression in patients infected with hepatitis C virus (HCV. We assessed host-related factors associated with a histologically advanced stage of this disease and determined the rate of liver fibrosis progression in HCV-infected patients. We included patients submitted to liver biopsy, who were anti-HCV and HCV RNA positive, who showed a parenteral risk factor (blood transfusion or intravenous drug use, and who gave information about alcohol consumption.Patients were divided into two groups for analysis: group 1 - grades 0 to 2; group 2 - grades 3 to 4. The groups were compared in terms of sex, age at the time of infection, estimated duration of infection and alcoholism. The rate of fibrosis progression (index of fibrosis was determined based on the relationship between disease stage and duration of infection (years. Logistic regression analysis revealed that age at the time of infection (P or = 40 years (median = 0.47. The main factors associated with a more rapid fibrosis progression were age at the time of infection and the estimated duration of infection. Patients who acquired HCV after 40 years of age showed a higher rate of fibrosis progression.

    Hepatitis B virus (HBV) infection is a dynamic state of interactions among HBV, hepatocytes, and the host immune system. Natural history studies of chronic hepatitis B (CHB) infection have shown an association between active viral replication and adverse clinical outcomes such as cirrhosis and hepatocellular carcinoma. The goal of therapy for CHB is to improve quality of life and survival by preventing progression of the disease to cirrhosis, decompensation, end-stage liver disease, hepatocellular carcinoma (HCC) and death. This goal can be achieved if HBV replication is suppressed in a sustained manner. The accompanying reduction in histological activity of CHB lessens the risk of cirrhosis and of HCC, particularly in non-cirrhotic patients. However, CHB infection cannot be completely eradicated, due to the persistence of covalently closed circular DNA in the nucleus of infected hepatocytes, which may explain HBV reactivation. Moreover, the integration of the HBV genome into the host genome may favour oncogenesis, development of HCC and may also contribute to HBV reactivation.

    2013-03-01

    Chronic liver disease (CLD) and several related extrahepatic manifestations such as hepatic osteodystrophy are associated with deficiency of vitamin D, which has therefore been suggested as therapeutic target. Vitamin D undergoes hepatic 25-hydroxylation, rendering the liver critical to the metabolic activation of this vitamin. Vitamin D deficiency is highly prevalent in CLD patients, and vitamin D levels are inversely related to the severity of CLD. Declining levels of carrier proteins such as albumin and vitamin D-binding protein might also be critical in CLD. Intervention studies report improvements of CLD following supplementation, and benefits to health outcomes in particular with respect to hepatitis C virus infection have recently been documented. We discuss vitamin D sources, functions and metabolism with a focus on the inherent complications of analytical measurements, such as the interference of 25-hydroxyvitamin D and 1,25-dihydroxyvitamin D C-3 epimers. Global discrepancies in the definition of optimal serum 25-hydroxyvitamin D levels are covered, and the prevalence of vitamin D deficiency in CLD is reviewed. We also address the functional mechanisms underlying this deficiency, and refer to associations between genetic variation in vitamin D metabolism and CLD. Lastly, we consider the health implications of a vitamin D deficiency in CLD and consider therapeutic options. Herein, we focus on the epidemiological and functional relationships between vitamin D deficiency and CLD, followed by a discussion of the potential implications for therapeutic interventions. © 2012 John Wiley & Sons A/S.

    The red blood cell distribution width (RDW) is increased in chronic liver disease, but its clinical significance in hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF) is still unclear. The aim of the present study was to investigate the clinical significance of RDW in HBV-ACLF patients. The medical records of HBV-ACLF patients who were admitted to The Second Affiliated Hospital of Anhui Medical University between April 2012 and December 2015 were retrospectively reviewed. Correlations between RDW, neutrophil lymphocyte ratio (NLR), and the model for end-stage liver disease (MELD) scores were analyzed using the Spearman's approach. Multivariable stepwise logistic regression test was used to evaluate independent clinical parameters predicting 3-month mortality of HBV-ACLF patients. The association between RDW and hospitalization outcome was estimated by receiver operating curve (ROC) analysis. Patient survival was estimated by Kaplan-Meier analysis and subsequently compared by log-rank test. Sixty-two HBV-ACLF patients and sixty CHB patients were enrolled. RDW were increased in HBVACLF patients and positively correlated with the NLR as well as MELD scores. Multivariate analysis demonstrated that RDW value was an independent predictor for mortality. RDW had an area under the ROC of 0.799 in predicting 3-month mortality of HBV-ACLF patients. Patients with HBV-ACLF who had RDW > 17% showed significantly poorer survival than those who had RDW ≤ 17%. RDW values are significantly increased in patients with HBV-ACLF. Moreover, RDW values are an independent predicting factor for an in-hospital mortality in patients with HBV-ACLF.

CLD affects Aboriginal North Americans disproportionately and is now one of the most common causes of death.Alcoholic liver disease is the leading etiology of CLD,but viral hepatitis, particularly hepatitis C, is an important and growing cause of CLD. High rates of autoimmune hepatitis and primary biliary cirrhosis (PBC) are reported in regions of coastal British Columbia and southeastern Alaska. Non-alcoholic liver disease is a common, but understudied, cause of CLD.Future research should monitor the incidence and etiology of CLD and should be geographically inclusive.In addition, more research is needed on the treatment of hepatitis C virus (HCV) infection and non-alcoholicfatty liver disease (NAFLD) in this population.

    As the result of various effects (viruses, metabolic diseases, nutritional factors, toxic agents, autoimmune processes) abnormal liver function, liver steatosis and connective tissue remodeling may develop. Progression of this process is complex including various pathways and a number of factors. The authors summarize the factors involved in the progression of chronic liver disease. They describe the role of cells and the produced inflammatory mediators and cytokines, as well as the relationship between the disease and the intestinal flora. They emphasize the role of oxidative stress, mitochondrial dysfunction and cell death in disease progression. Insulin resistance and micro-elements (iron, copper) in relation to liver damage are also discussed, and genetic and epigenetic aspects underlying disease progression are summarized. Discovery of novel treatment options, assessment of the effectiveness of treatment, as well as the success and proper timing of liver transplantation may depend on a better understanding of the process of disease progression.

    Full Text Available The complement is thought to be involved in the pathogenesis of multiple liver disorders. However, its role in patients with HBV related acute-on-chronic liver failure (HBV-ACLF remains unclear. Serum levels of the third and fourth complement components (C3, C4 and complement function (CH50 were examined in this prospective, observational study. Associations between their expression and disease activity were analyzed. Survival was analyzed by Kaplan-Meier curves. Predictors of clinical outcome were determined by Cox regression analysis. C3, C4, and CH50 levels were significantly lower in HBV-ACLF patients compared to controls. C3, C4, and CH50 levels were negatively correlated with Tbil levels but positively associated with PTA levels. C3 levels were negatively associated with MELD-Na. C3 levels were significantly lower in HBV-ACLF patients who died compared to patients who survived. In a median hospital stay of 39 days, mortality occurred in 41 patients with a progressive increase based on C3 grade (P=0.008. The actuarial probability of developing mortality was significantly higher in patients with low C3 grade compared to those with high C3 grade (P<0.001. Multivariate Cox regression analysis showed that C3 levels were an independent predictor of mortality. Complement played a pathogenic role in HBV-ACLF patients and C3 was an independent predictor of mortality.

    Acute-on-chronic liver failure (ACLF) is a distinct entity that differs from acute liver failure and decompensated cirrhosis in timing, presence of treatable acute precipitant, and course of disease, with a potential for self-recovery. The core concept is acute deterioration of existing liver function in a patient of chronic liver disease with or without cirrhosis in response to an acute insult. The insult should be a hepatic one and presentation in the form of liver failure (jaundice, encephalopathy, coagulopathy, ascites) with or without extrahepatic organ failure in a defined time frame. ACLF is characterized by a state of deregulated inflammation. Initial cytokine burst presenting as SIRS, progression to CARS and associated immunoparalysis leads to sepsis and multi-organ failure. Early identification of the acute insult and mitigation of the same, use of nucleoside analogue in HBV-ACLF, steroid in severe alcoholic hepatitis, steroid in severe autoimmune hepatitis and/or bridging therapy lead to recovery, with a 90-day transplant-free survival rate of up to 50 %. First-week presentation is crucial concerning SIRS/sepsis, development, multiorgan failure and consideration of transplant. A protocol-based multi-disciplinary approach including critical care hepatology, early liver transplant before multi-organ involvement, or priority for organ allocation may improve the outcome. Presentation with extrahepatic organ involvement or inclusion of sepsis as an acute insult in definition restricts the therapy, i.e., liver transplant or bridging therapy, and needs serious consideration. Augmentation of regeneration, cell-based therapy, immunotherapy, and gut microbiota modulation are the emerging areas and need further research.

    Obstructive sleep apnea (OSA) is characterized by chronic intermittent hypoxia (CIH). OSA is associated with nonalcoholic steatohepatitis (NASH) in obese subjects. The aim of this study was to investigate the effects of CIH on the liver in the absence of obesity. Lean C57BL/6J mice (n = 15) on a regular chow diet were exposed to CIH for 12 weeks and compared with pair-fed mice exposed to intermittent air (IA, n = 15). CIH caused liver injury with an increase in serum ALT (224 +/- 39 U/l versus 118 +/- 22 U/l in the IA group, P fasting serum insulin levels, and mild elevation of fasting serum total cholesterol and triglycerides (TG). Liver TG content was unchanged, whereas cholesterol content was decreased. Histology showed swelling of hepatocytes, no evidence of hepatic steatosis, and marked accumulation of glycogen in hepatocytes. CIH led to lipid peroxidation of liver tissue with a malondialdehyde (MDA)/free fatty acids (FFA) ratio of 0.54 +/- 0.07 mmol/mol versus 0.30 +/- 0.01 mmol/mol in control animals (P obesity, CIH leads to mild liver injury via oxidative stress and excessive glycogen accumulation in hepatocytes and sensitizes the liver to a second insult, whereas NASH does not develop.

    To investigate changes in hepatic and splenic stiffness in patients without chronic liver disease during liver resection for hepatic tumors. Patients scheduled for liver resection for hepatic tumors were considered for enrollment. Tissue stiffness measurements on liver and spleen were conducted before and two days after liver resection using point shear-wave elastography. Histological analysis of the resected liver specimen was conducted in all patients and patients with marked liver fibrosis were excluded from further study analysis. Patients were divided into groups depending on size of resection and whether they had received preoperative chemotherapy or not. The relation between tissue stiffness and postoperative biochemistry was investigated. Results are presented as median (interquartile range). 35 patients were included. The liver stiffness increased in patients undergoing a major resection from 1.41 (1.24-1.63) m/s to 2.20 (1.72-2.44) m/s ( P = 0.001). No change in liver stiffness in patients undergoing a minor resection was found [1.31 (1.15-1.52) m/s vs 1.37 (1.12-1.77) m/s, P = 0.438]. A major resection resulted in a 16% (7%-33%) increase in spleen stiffness, more ( P = 0.047) than after a minor resection [2 (-1-13) %]. Patients who underwent preoperative chemotherapy ( n = 20) did not differ from others in preoperative right liver lobe [1.31 (1.16-1.50) vs 1.38 (1.12-1.56) m/s, P = 0.569] or spleen [2.79 (2.33-3.11) vs 2.71 (2.37-2.86) m/s, P = 0.515] stiffness. Remnant liver stiffness on the second postoperative day did not show strong correlations with maximum postoperative increase in bilirubin ( R 2 = 0.154, Pearson's r = 0.392, P = 0.032) and international normalized ratio ( R 2 = 0.285, Pearson's r = 0.534, P = 0.003). Liver and spleen stiffness increase after a major liver resection for hepatic tumors in patients without chronic liver disease.

    Oral lichen planus (OLP) is seen frequently in patients with hepatitis C virus (HCV) infection. The aim of this study was to evaluate the occurrence of oral candidiasis, other mucosal lesions, and xerostomia during interferon (IFN) therapy for HCV infection. Of 124 patients with HCV-infected liver diseases treated with IFN therapy in our hospital, 14 (mean age 56.00 ± 12.94 years) who attended to receive administration of IFN once a week were identified and examined for Candida infection and other oral lesions and for the measurement of salivary flow. Serological assays also were carried out. Cultures of Candida from the tongue surfaces were positive in 7 (50.0%) of the 14 patients with HCV infection at least once during IFN therapy. C. albicans was the most common species isolated. The incidence of Candida during treatment with IFN did not increase above that before treatment. Additional oral mucosal lesions were observed in 50.0% (7/14) of patients: OLP in three (21.4%), angular cheilitis in three (21.4%) and recurrent aphthous stomatitis in one (7.1%). OLP occurred in one patient before treatment with IFN, in one during treatment and in one at the end of treatment. 85.7% of the oral lesions were treated with topical steroids. We compared the characteristics of the 7 patients in whom Candida was detected at least once during IFN therapy (group 1) and the 7 patients in whom Candida was not detected during IFN therapy (group 2). The prevalence of oral mucosal lesions (P=0.0075) and incidence of external use of steroids (P=0.0308) in group 1 were significantly higher than in group 2. The average body weight of group 1 decreased significantly compared to group 2 (P=0.0088). Salivary flow decreased in all subjects throughout the course of IFN treatment and returned at 6th months after the end of treatment. In group 1, the level of albumin at the beginning of the 6th month of IFN administration was lower than in group 2 (P=0.0550). According to multivariate analysis

    Coffee intake is associated with reduced risk of liver cancer and chronic liver disease as reported in previous studies, including prospective ones conducted in Asian populations where hepatitis B viruses (HBVs) and hepatitis C viruses (HCVs) are the dominant risk factors. Yet, prospective studies in Western populations with lower HBV and HCV prevalence are sparse. Also, although preparation methods affect coffee constituents, it is unknown whether different methods affect disease associations. We evaluated the association of coffee intake with incident liver cancer and chronic liver disease mortality in 27,037 Finnish male smokers, aged 50-69, in the Alpha-Tocopherol, Beta-Carotene Cancer Prevention Study, who recorded their coffee consumption and were followed up to 24 years for incident liver cancer or chronic liver disease mortality. Multivariate relative risks (RRs) and 95% confidence intervals (CIs) were estimated by Cox proportional hazard models. Coffee intake was inversely associated with incident liver cancer (RR per cup per day=0.82, 95% CI: 0.73-0.93; P-trend across categories=0.0007) and mortality from chronic liver disease (RR=0.55, 95% CI: 0.48-0.63; P-trendcoffee. These findings suggest that drinking coffee may have benefits for the liver, irrespective of whether coffee was boiled or filtered.

    Liver scintigrams with Tc-99m phytate were reviewed in a total of 64 consecutive patients, comprising 28 with chronic hepatitis and 36 with liver cirrhosis. Reticuloendothelial (RES) function, plasma endotoxin (Et) levels and findings of general liver function tests were used as reference parameters to determine the diagnostic ability of liver scintigraphy. Multivariate analyses revealed that liver scintigrams had a strong correlation with RES function and Et levels in terms of morphology of the liver and hepatic and bone marrow Tc-99m uptake. General liver function tests revealed gamma globulin to be correlated with hepatic uptake and the degree of splenogemaly on liver scintigrams; and ICG levels at 15 min to be correlated with bone marrow and splenic uptake. Accuracy of liver scintigraphy was 73% for chronic hepatitis, which was inferior to general liver function tests (83%). When both modalities were combined, diangostic accuracy increased to 95%. Liver scintigraphy seems to be useful as a complementary approach. (Namekawa, K).

  15. Pruritus in chronic cholestatic liver diseases

    2017-01-01

    Full Text Available Pruritus can be a prominent symptom  in patients with chronic liver disorders, especially those  with cholestasis,  and  substantially  affects  quality  of life. Management of pruritus  in cholestatic  liver diseases  remains  a  complicated   medical  problem. The review article deals with pathophysiological mechanisms of pruritus in cholestatic liver diseases, in particular, with the role of bile acids, endogenous opioids, serotonin, and histamine. There is new data on the key pathophysiological elements, such as neuronal activation lysophosphatidic acid and autotaxin, an enzyme that produces lysophosphatidic acid and whose serum activity is associated with the intensity of pruritus. Pathophysiology-based management approaches include administration of anionic exchange resin cholestyramine, ursodeoxycholic acid, rifampicin agonists, an opioid antagonist naltrexone and a  serotonin-reuptake inhibitor sertraline. These agents are recommended for the use as a stepped treatment algorithm. Patients who do not respond to these therapies can become candidates for albumin dialysis, plasmapheresis, ultraviolet B phototherapy, or need some other individualized approaches. New knowledge on the pathophysiology of pruritus may potentially result in the development of new agents for cholestatic pruritus.

    Viral hepatitis is among the important health problems in Egypt which lead to chronic hepatitis and liver cirrhosis.Liver cirrhosis is associated with circulatory disturbances which are attributed to arterial vasodilatation that results from overproduction or reduced degradation of vasodilator substances. Adrenomedullin (AM) is responsible for the arteriolar vasodilatation and hyper dynamic circulation in liver cirrhosis. The aim of work was to the assessment patients with chronic hepatitis and liver cirrhosis with or without renal impairment by determining the level of AM and comparing them with healthy controls. 44 patients with chronic liver diseases (14 patients with chronic hepatitis and 30 patients with liver cirrhosis, 16 in Child-Pugh's class A, 8 in Child-Pugh's class B, and 6 in Child-Pugh's class C) were examined clinically, laboratory, ultrasonography and endoscopically. Plasma concentration of adrenomedullin was measured in all patients and 15 normal controls.The mean levels of AM were higher in patients with chronic hepatitis and patients with liver cirrhosis compared to controls (0.52 ± 0.19 ng/ml , 0.67 ± 0.16 ng/ml and 0.35 ± 0.12 ng/ml, respectively; p<0.001). The mean levels of plasma aldosterone concentration were higher in patients with chronic hepatitis and patients with liver cirrhosis compared to controls (256 ± 197 ng/dl 358 ± 264 ng/dl and 179 ± 142 ng/dl, respectively; p<0.001). The mean levels of creatinine clearance were lower in patients with chronic hepatitis and patients with liver cirrhosis compared to controls (0.31±0.19 ml/min 0.25±0.21 ml/min and 0.45±0.37 ml/min, respectively; p<0.001). The mean levels of AM were higher in patients with liver cirrhosis with renal impairment than without. Also there was significant difference in AM levels between patients with and without esophageal varices (0.71 ± 0.22 ng/ml and 0.52 ± 0.17 ng/ml respectively, p<0.05). AM levels between patients with and without ascites

    Full Text Available Assessing risk of adverse outcomes among patients with chronic liver disease has been challenging due to non-linear disease progression. We previously developed accurate prediction models for fibrosis progression and clinical outcomes among patients with advanced chronic hepatitis C (CHC. The primary aim of this study was to validate fibrosis progression and clinical outcomes models among a heterogeneous patient cohort.Adults with CHC with ≥3 years follow-up and without hepatic decompensation, hepatocellular carcinoma (HCC, liver transplant (LT, HBV or HIV co-infection at presentation were analyzed (N = 1007. Outcomes included: 1 fibrosis progression 2 hepatic decompensation 3 HCC and 4 LT-free survival. Predictors included longitudinal clinical and laboratory data. Machine learning methods were used to predict outcomes in 1 and 3 years.The external cohort had a median age of 49.4 years (IQR 44.3-54.3; 61% were male, 80% white, and 79% had genotype 1. At presentation, 73% were treatment naïve and 31% had cirrhosis. Fibrosis progression occurred in 34% over a median of 4.9 years (IQR 3.2-7.6. Clinical outcomes occurred in 22% over a median of 4.4 years (IQR 3.2-7.6. Model performance for fibrosis progression was limited due to small sample size. The area under the receiver operating characteristic curve (AUROC for 1 and 3-year risk of clinical outcomes was 0.78 (95% CI 0.73-0.83 and 0.76 (95% CI 0.69-0.81.Accurate assessments for risk of clinical outcomes can be obtained using routinely collected data across a heterogeneous cohort of patients with CHC. These methods can be applied to predict risk of progression in other chronic liver diseases.

    There have been a number of reports of gastric emptying in cirrhosis, all with unconfirmed results. Moreover, the mechanism for delayed emptying in cirrhotic patients in unclear. We evaluated gastric emptying in patients with chronic hepatitis and cirrhosis by means of gastric emptying scintigraphy. The subjects were 18 normal controls and 75 patients with chronic viral hepatitis (50 patients had chronic hepatitis and 25 patients had cirrhosis). Tc-99m diethyltriamine pentaacetic acid labeled solid meals were used to evaluate gastric emptying; the half-time (T 1/2) of which was calculated. Digestive symptom scores were determined at the time of gastric emptying tests. Fourteen (28%) of 50 patients with chronic hepatitis and 16 (64%) of 25 patients with cirrhosis had delayed gastric emptying. T 1/2 in patients with cirrhosis was significantly higher than that in normal controls and patients with chronic hepatitis (p=0.0001 and 0.0003, respectively). The difference between T 1/2 in patients with chronic hepatitis and that in normal controls was not significant. On regression analysis, two indices, the serum albumin level and platelet count, were found to be significantly related to delayed gastric emptying. Gastric emptying was more delayed in cirrhotic patients than in those with chronic hepatitis and normal controls. Delayed gastric emptying may be related to liver function and portal hypertension.

    Doppler echocardiography (Echo) is a non-invasive method of excellent accuracy to screen portopulmonary hypertension (PPH) and to assess intrapulmonary shunts (IPS) in chronic liver disease (CLD). In the past decade, Echo proved to play a fundamental role in the diagnosis of cirrhotic cardiomyopathy (CCM). To perform a systematic review of relevant articles on the subject 'Echo in CLD'. In November 2011, a systematic review was performed in the PubMed, LILACS and SciELO databases, and the characteristics of the studies selected were reported. The search based on descriptors and free terms obtained 204 articles (179 in Pubmed, 21 in LILACS, and 1 in SciELO). Of those 204 articles, 22 were selected for systematic review. A meta-analysis could not be performed because of the heterogeneity of the articles. Echo should be part of CLD stratification for screening PPH, IPS and CCM, because, most of the time, such complications are diagnosed only when patients are already waiting for a liver transplant.

    Full Text Available The occurrence of depression is higher in patients with chronic liver disease (CLD than that in the general population. The mechanism described in previous studies mainly focused on inflammation and stress, which not only exists in CLD, but also emerges in common chronic diseases, leaving the specific mechanism unknown. This review was to summarize the prevalence and risk factors of depression in CLD including chronic hepatitis B, chronic hepatitis, alcoholic liver disease, and non-alcoholic fatty liver disease, and to point out the possible underlying mechanism of this potential link. Clarifying the origins of this common comorbidity (depression and CLD may provide more information to understand both diseases.

    Full Text Available Introduction: Liver disease results in complex pathophysiologic disturbances affecting nutrient digestion, absorption, distribution, storage, and use. This article aimed to present a classification of metabolic disturbances in chronic liver disease in children?   Materials and Methods: In this review study databases including proquest, pubmedcentral, scincedirect, ovid, medlineplus were been searched with keyword words such as” chronic liver disease"  ” metabolic disorder””children” between 1999 to 2014. Finally, 8 related articles have been found.   Results: Metabolic disorder in this population could be categorized in four set: 1carbohydrates, 2proteins,3 fats and 4vitamins. 1 Carbohydrates: Children with CLD are at increased risk for fasting hypoglycemia, because the capacity for glycogen storage and gluconeogenesis is reduced as a result of abnormal hepatocyte function and loss of hepatocyte mass. 2 Proteins: The liver’s capacity for plasma protein synthesis is impaired by reduced substrate availability, impaired hepatocyte function, and increased catabolism. This results in hypoalbuminemia, leading to peripheral edema and contributing to ascites. Reduced synthesis of insulin-like growth factor (IGF-1 and its binding protein IGF-BP3 by the chronically diseased liver results in growth hormone resistance and may contribute to the poor growth observed in these children. 3 Fats: There is increased fat oxidation in children with end-stage liver disease in the fed and fasting states compared with controls, which is probably related to reduced carbohydrate availability. The increased lipolysis results in a decrease in fat stores, which may not be easily replenished in the setting of the fat malabsorption that accompanies cholestasis. Reduced bile delivery to the gut results in impaired fat emulsification, and hence digestion. The products of fat digestion are also poorly absorbed, because bile is also required for micelle formation

  4. Mineral Requirements in Children with Chronic Liver Disease

    Full Text Available Introduction: Decreased oral intake or impaired function / structure in the gut, such as hypertension port associated with atrophic changes in the protein nutrition - calories can lead to micronutrient deficiencies.This paper examines the status of micronutrients in chronic liver disease in children.   Materials and Methods: In this review study databases including proquest, pubmedcentral, scincedirect, ovid, medlineplus were been searched with keyword words such as” chronic liver disease"” minerals””children” between 1999 to 2014. Finally, 3 related articles have been found.   Results: In chronic liver disease changes in micronutrient metabolism lead to changes in the daily requirements, such that in certain circumstances intake increasing or decreasing  is needed. Low serum calcium and phosphate concentrations are often the reflection of malabsorption-induced bone disease that is unresponsive to vitamin D store normalization. Iron is usually deficient in children with CLD and supplementation frequently needed. The origin of iron deficiency is multifactorial and includes ongoing losses, inadequate intakes, serial blood draws and malabsorption secondary to hypertensive enteropathy. Zinc plays an important role in cognitive function, appetite and taste, immune function, wound healing, and protein metabolism. Low plasma zinc levels are frequent in children with chronic cholestasis, but unfortunately plasma concentrations are not reflective of total body zinc status. Copper and manganese, unlike other minerals, are increased in CLD, because they are normally excreted through bile. Parenteral nutrition in cholestatic patients can induce manganese intoxication and accumulation in basal ganglia.   Conclusion:  In fants with CLD are prone to multiple nutritional deficiencies. Mineral state should be evaluated, treated and reevaluated, until sufficient daily requirement achieved. Poster  Presentation, N 33

    To evaluate the diagnostic value of sonographic irregularities of liver surface in the differentiation of chronic liver disease. Fifty-eight patients with either chronic hepatitis or early stage of liver cirrhosis were examined with 5 MHz linear array transducer by observing the liver surface.We compared the sonographic findings with peritoneoscopic and pathologic findings. Thirty-five patients with smooth surface showed variable pathological results, including chronic active and persistent hepatitis, inactive hepatitis and alcoholic hepatitis without any evidence of cirrhosis. Nineteen patients with micronodules mostly revealed chronic active hepatitis and cirrhosis. All 4 patients with macronodules were proved pathologically ascirrhosis. High resolution ultrasonography(HRUS) showed smooth liver surface in 35 patients(60.3%),micronodular surface in l9(32.8%), and macronodular surface in 4 (6.9%). Twenty-one cases(60.0%) among 35 patients with smooth surface were peritoneoscopically normal and 12 cases(34.3%) showed dimpling surface. However among l9 patients with micronodular surface, only 5 cases(26.3%) showed micronodular surface on peritoneoscopy. while 8 cases(42.l%) showed nracronodular surface and 6 cases(3l.6%) dimpling surface. All 4 patients with macronodulesrevealed peritoneoscopically nracronodular surface. Observation of liver surface by HRUS was useful in predicting the progression of chronic hepatitis to cirrhosis. However, it was not helpful in the differentiation between normal liver and chronic hepatrtrs

    Living related liver transplantation (LRLT) has been developed in response to the paediatric organ donor shortage. According to the International Living Donor Registry, 521 transplants had been performed in 515 patients between December 8 1988 and January 19 1996 in 30 centres worldwide. The overall actuarial patient and graft survival rates were 82.7 and 80%, respectively. Between June 17 1994 and November 30 1996, the authors performed 11 LRLT at the Chung Gung Memorial Hospital. The living donors consisted of 10 mothers and one father. The mean graft weight was 303 g and the mean graft recipient weight ratio was 2.2%. Donor hepatectomy was performed without vascular inflow occlusion. The intra-operative blood loss ranged from 30 mL to 120 mL with an average of 61 mL, and blood transfusion was not required in all donors both intra-operatively and during the postoperative period. Underlying diseases of the recipients were biliary atresia (n = 10) and glycogen storage disease (n = 1). The mean graft cold ischaemia time was 106 min, the mean second warm ischaemia time was 51 min and the mean interval between portal and arterial reperfusion was 81 min. The initial LRLT results were promising with all donors having been discharged without complication. The recipients experienced a few complications, all of which were manageable with early intervention. All 11 recipients are alive and well. These are encouraging results and the authors hope to expand the use of live donors for liver transplantation to cope with demand.

    The purpose of this study was to investigate the chronological relationship between scan delay and liver enhancement for the hepatobiliary phase on Gd-EOB-DTPA-enhanced MRI and evaluate the effects of liver function on liver enhancement. Hepatobiliary-phase images were retrospectively evaluated in 125 patients with chronic liver disease. Hepatobiliary phase images were obtained at 5, 10, 15, and 20 min after injection. We calculated relative liver enhancement (RLE) at t min after injection by dividing the signal intensity (SI) of the liver at t min by precontrast SI. We compared RLE values at 5, 10, 15, and 20 min and evaluated the detectability of focal hepatic lesions. We analyzed the effect of liver function on RLE with the generalized linear model. There was not significant difference in RLE and lesion detectability at 15 and 20 min. RLE in the Child-Pugh C group was significantly lower than in the Child-Pugh A and B groups. The serum albumin level and prothrombin time were significantly correlated with the liver enhancement. A delay time of 15 min for the hepatobiliary phase was thought to be adequate in patients with mild liver dysfunction. The serum albumin level and prothrombin time would be predictive of liver enhancement in the hepatobiliary phase. (author)

    Chronic viral liver disease is often associated with other conditions. Diabetes mellitus (DM) is frequently reported in this context and may play a role in the progression of the liver disease to hepatocellular carcinoma (HCC). Renal disease is also an important extrahepatic manifestation of hepatitis viral infection and its presence is associated with poor prognosis and management issues. Our study had multiple purposes: to determine the frequency of the association between chronic viral liver disease and diabetes mellitus, evaluate the potential of diabetes mellitus as a risk factor for HCC and assess an eventual renal involvement. We included in our study a number of 246 patients with chronic liver disease, from whom 136 were diagnosed with chronic viral hepatitis and 110 with viral liver cirrhosis. These patients were assessed by using a clinical examination and a series of tests, including serum transaminase levels, serum bilirubin, serum albumin, markers of cholestasis, fasting plasma glucose levels, serum creatinine, urea, albuminuria, Addis-Hamburger test, electrophoresis of urinary proteins, abdominal ultrasound and, in some cases, CT examination. We obtained the following results: diabetes mellitus is often associated with chronic liver disease of viral etiology, having been identified in 18.29% of the patients in our study. Age above 60 in patients with chronic hepatitis (p=0.013diabetes mellitus. Renal disease was present in 13.4% of the patients with chronic liver disease and it was especially associated with liver cirrhosis and hepatitis C virus. The most common form of renal injury was glomerulonephritis. Acute kidney injury was diagnosed only in cirrhotic patients as hepatorenal syndrome, occurring in 7.27% of the subjects, while chronic kidney disease was identified only in two cases of chronic viral hepatitis. Four patients in our study were diagnosed with HCC and none of them presented diabetes mellitus. Our study revealed that there is a

    Currently the common pathogenetic mechanisms in nonalcoholic fatty liver disease (NAFLD) and obstructive sleep apnea (OSA) are gaining increased attention. The aim of this study is to find out the influence of chronic intermittent hypoxemia and OSA related parameters to the severity of NAFLD. We examined the liver functions tests and ultrasonographic data of liver as well as markers of OSA severity (apnea-hypopnea index [AHI], oxygen desaturation index, minimum oxygen saturation, percentage of time spent with S(pO(2)) hypoxia during sleep. The prevalence of NAFLD was higher in patients with severe OSA, suggesting a role for nocturnal hypoxemia in the pathogenesis of fatty liver disease.

  14. Proteomic analysis of liver in rats chronically exposed to fluoride.

    Full Text Available Fluoride (F is a potent anti-cariogenic element, but when ingestion is excessive, systemic toxicity may be observed. This can occur as acute or chronic responses, depending on both the amount of F and the time of exposure. The present study identified the profile of protein expression possibly associated with F-induced chronic hepatotoxicity. Weanling male Wistar rats (three-weeks old were divided into three groups and treated with drinking water containing 0, 5 or 50 mg/L F for 60 days (n=6/group. At this time point, serum and livers were collected for F analysis, which was done using the ion-sensitive electrode, after hexamethyldisiloxane-facilitated diffusion. Livers were also submitted to histological and proteomic analyses (2D-PAGE followed by LC-MS/MS. Western blotting was done for confirmation of the proteomic data A dose-response was observed in serum F levels. In the livers, F levels were significantly increased in the 50 mg/L F group compared to groups treated with 0 and 5 mg/L F. Liver morphometric analysis did not reveal alterations in the cellular structures and lipid droplets were present in all groups. Proteomic quantitative intensity analysis detected 33, 44, and 29 spots differentially expressed in the comparisons between control vs. 5 mg/L F, control vs. 50 mg/L F, and 5 mg/L vs. 50 mg/L F, respectively. From these, 92 proteins were successfully identified. In addition, 18, 1, and 5 protein spots were shown to be exclusive in control, 5, and 50 mg/L F, respectively. Most of proteins were related to metabolic process and pronounced alterations were seen for the high-F level group. In F-treated rats, changes in the apolipoprotein E (ApoE and GRP-78 expression may account for the F-induced toxicity in the liver. This can contribute to understanding the molecular mechanisms underlying hepatoxicity induced by F, by indicating key-proteins that should be better addressed in future studies.

    Infiltrating monocytes have been demonstrated to contribute to tissue damage in experimental models of liver injury and fibrosis. However, less is known about monocyte infiltration in the livers of patients with chronic liver diseases (CLD). In the present study, we demonstrated that CD68+ hepatic macrophages and MAC387+ infiltrating monocytes were significantly increased in the livers of CLD patients with different etiologies as compared with normal liver tissue. In addition, CLD patients with higher inflammatory grading scores had more CD68+ macrophages and MAC387+ monocytes infiltration in their livers compared to those with lower scores. Significantly more MAC387+ infiltrating monocytes were found in the liver tissue of CLD patients with higher fibrotic staging scores compared to those with lower scores. Monocyte chemoattractant protein-1 (MCP-1) expression was significantly increased in the livers of CLD patients with different etiologies. MCP-1 staining scores were significantly positively associated with the numbers of MAC387+ infiltrating monocytes in CLD patients. Taken together, our results demonstrate that infiltrating monocytes may play a pathological role in exacerbating chronic liver inflammation and fibrosis in CLD. MCP-1 may be involved in the monocyte infiltration and progression of liver inflammation and fibrosis in CLD.

    Full Text Available BACKGROUND Liver plays an important role in normal erythropoiesis and synthesis of clotting factors. Chronic liver disease (CLD patients are frequently associated with abnormalities in haematological parameters. MATERIALS AND METHODS This was an observational study conducted among diagnosed CLD patients over a period of 1 year from 2013 to 2014. Various haematological abnormalities in 75 CLD patients were studied. Relevant details were obtained in structured format. RESULTS The mean age of the study group 49.2 years. Male-to-female ratio was 5.8:1. Aetiologies of cirrhosis were alcoholism (61.3%, diabetes mellitus (26.7% and dyslipidaemia (13%. 88% patients were anaemic with severe anaemia (Hb <8 gm% observed in 33.3% patients with mean Hb being 8.76 gm%. Mean Hb in alcohol-related CLDs were lower than CLDs due to other aetiologies (8.62 gm% vs. 9.36 gm%. Most common anaemia observed was normocytic normochromic anaemia (40.9%. 26.7% had leucopenia and 88% had thrombocytopenia. Normal ferritin levels were observed in 6.7%, decreased in 16% and increased in the remaining cases of which a level of more than 900 ng/mL was observed in 18.7% cases. Mean CTP (ChildTurcotte-Pugh score of the study group was 11.1. 80% of patients belong to child C. Patients with high ferritin levels had high CTP score (P-0.001. Platelet count decreases as CTP score increases (P-0.000 and as spleen size increases (P-0.001. CONCLUSION Most common haematological abnormalities observed were thrombocytopenia and anaemia. Severe anaemia was seen in males and alcoholics. Thrombocytopenia was more in those with advanced liver disease and large spleen. High serum ferritin level correlate well with advanced liver disease.

    Objective: To determine the coagulation abnormalities and relationship between abnormal clotting tests and the risk of gastrointestinal bleeding (GI) among chronic liver disease (CLD) patients admitted at a tertiary care hospital in Pakistan. Methods: Adult CLD patients admitted at Liaquat University Hospital Jamshoro, during Nov 2004 - Oct 2005, were included in the study. The patients blood were tested for coagulation abnormalities including prothrombin time (PT), activated partial thromboplastin time (aPTT), platelet count and plasma fibrinogen. Association was seen between the abnormal clotting tests and the gastrointestinal bleeding by calculating relative risk (RR) with 95% confidence interval. Results: PT was prolonged in 88% and aPTT was raised in 71% cases of CLD. Both PT and aPTT were prolonged in 67% CLD cases. Approximately 37% CLD cases had decreased platelet count and 15% cases had decreased serum fibrinogen level. Relative risk of GI bleeding with abnormal clotting tests in CLD cases were weakly positive for PT (RR = 1.02; 95% CI, 0.49-2.10), negative for aPTT (RR=0.83; 95% CI, 0.47-1.45), strongly positive for decreased platelet counts (RR = 1.96; 95% CI, 1.08-3.56) and also for decreased fibrinogen level (RR = 1.47; 95% CI, 0.64-3.35). Conclusion: Coagulation abnormalities were profound in CLD. Decrease platelet counts and fibrinogen levels were related with GI bleeding but PT and aPTT were not significantly related with GI bleeding in patients with chronic liver disease. Nevertheless, these parameters (PT and aPTT) were still used as prognostic markers. (author)

  20. Mitochondrial Roles and Cytoprotection in Chronic Liver Injury

    Directory of Open Access Journals (Sweden)

    Davide Degli Esposti

    2012-01-01

    Full Text Available The liver is one of the richest organs in terms of number and density of mitochondria. Most chronic liver diseases are associated with the accumulation of damaged mitochondria. Hepatic mitochondria have unique features compared to other organs' mitochondria, since they are the hub that integrates hepatic metabolism of carbohydrates, lipids and proteins. Mitochondria are also essential in hepatocyte survival as mediator of apoptosis and necrosis. Hepatocytes have developed different mechanisms to keep mitochondrial integrity or to prevent the effects of mitochondrial lesions, in particular regulating organelle biogenesis and degradation. In this paper, we will focus on the role of mitochondria in liver physiology, such as hepatic metabolism, reactive oxygen species homeostasis and cell survival. We will also focus on chronic liver pathologies, especially those linked to alcohol, virus, drugs or metabolic syndrome and we will discuss how mitochondria could provide a promising therapeutic target in these contexts.

    The purpose of this study was to evaluate change in the proton MR spectroscopic ( 1 H-MRS) features of the liver according to changes in the severity of the chronic hepatitis spectrum (normal-chronic hepatitis-liver cirrhosis), and to determine the possibility of replacing liver biopsy by 1 H-MRS. Sixty profiles of 1 H-MRS features from 15 normal volunteers, 30 cases of chronic hepatitis, and 15 of liver cirrhosis were evaluated. All cases of chronic hepatitis and liver cirrhosis were confirmed by biopsy, and histopathologic disease severity was categorized according to Ludwig's classification. Using the STEAM (STimulated Echo-Aquisition Mode) sequence, 1 H-MRS was performed. The ratios of peak areas of (glutamate + glutamine)/lipid, phosphomonoesters/lipid, (glycogen + glucose)/lipid, and (3.9-4.1 ppm unknown peak)/lipid and their mean and standard deviation were calculated in normal, chronic hepatitis stages I and II, and early and late liver cirrhosis groups and the results were compared between these groups. One-way variable analysis was applied to the statistics. Mean and standard deviation of phosphomonoesters/lipid in the normal, chronic hepatitis grades I and II, and early and late liver cirrhosis groups were 0.0146±0.0090, 0.0222±0.0170, 0.0341±0.0276, 0.0698±0.0360, and 0.0881±0.0276, respectively, and (glycogen + glucose)/lipid were 0.0403±0.0267, 0.0922±0.0377, 0.1230±0.0364, 0.1853±0.0667, 0.2325±0.1071, respectively. These results implied that the ratio of the above metabolites to lipid content increased according to increasing disease severity (p less than 0.05). For (glutamate + glutamine)/lipid however, the ratios for each group were 0.0204±0.0067, 0.0117±0.0078, 0.0409±0.0167, 0.0212±0.0103, and 0.0693±0.0371, respectively, and there was no correlation with disease severity. In the chronic hepatitis grades I and II, and early and late liver cirrhosis groups, the ratios for (3.9-4.1 ppm unknown peak)/lipid were 0.0302±0.0087, 0

    Background: Chronicity of liver disease is determined either by duration of liver disease or by evidence of either severe liver disease or physical stigmata of chronic liver disease. Chronic liver disease may be caused commonly by persistent viral infections, metabolic diseases, drugs, autoimmune hepatitis, or unknown factors. The objective of this study was to find out the aetiology of chronic liver disease (CLD) in children. Methodology: It was a descriptive, prospective study which used a structured proforma designed to collect data of cases of CLD from both indoor and outdoor Paediatrics units of Fauji Foundation Hospital, Rawalpindi, and Children Hospital, Pakistan Institute of Medical Sciences, Islamabad. All children under 12 years having either clinical or biochemical evidence of liver disease and/or elevated liver enzymes for more than 3 months were included in this study. Results: Sixty cases of CLD were enrolled from indoor and outdoor units from January 2010 to July 201. Thirty nine (65%) cases were male and 21 (35%) were female. Eleven children were less than 1 year, 18 were 1-5 years old and 31 were 5-12 years of age. Viral hepatitis was the most common cause found in 22 (36.7%) cases. Out of these 22 patients with viral aetiology 19 (31.66%) patients had Hepatitis C and 3 (5%) had Hepatitis B. Glycogen storage disease was seen in 8.3% cases, and biliary atresia and Wilson disease in 6.7% each. Other less commonly found cases were autoimmune hepatitis, TORCH infections, hepatoma and drug induced hepatitis (1.7% each). Cause couldn't be established in 35% cases which remained idiopathic. Conclusion: Viral hepatitis is the leading cause of chronic liver disease in children, with the highest incidence of chronic Hepatitis C followed by metabolic disorders (glycogen storage disease and Wilson disease) and biliary atresia. Chronic viral hepatitis was most prevalent between 11 months to 12 years of age. Wilson disease was common in 3-7 years age group, and

    Portal circulation has been evaluated by per-rectal portal scintigraphy in 21 controls and in 30 pts affected by chronic liver diseases. Tc99m-pertechnetate (10 mci) was given through a Nelaton's catheter in the upper rectum; a per-rectal portal shunt index (SI) was calculated. A relevant overlap is evident between controls and CHP pts; no overlap exists between controls and B or C graded cirrhosis. We conclude that the technique may be suggested to monitor the course of chronic liver diseases and different therapeutic regimens. (orig.) [de

    Minimal encephalopathy was originally associated with chronic liver disease but is increasingly associated with most other chronic diseases and particularly with diabetes and also chronic disorders in other organs: kidneys, lungs, thyroid and with obesity. It is increasingly with dramatically increased and more or less permanent increase in systemic inflammation, most likely a result of Western lifestyle. Frequent physical exercise and intake of foods rich in vitamins, antioxidants, fibres, lactic acid bacteria etc in combination with reduction in intake of refined and processed foods is known to reduce systemic inflammation and prevent chronic diseases. Some lactic acid bacteria, especially Lb paracasei, lb plantarum and pediococcus pentosaceus have proven effective to reduce inflammation and eliminate encephalopathy. Significant reduction in blood ammonia levels and endotoxin levels were reported in parallel to improvement of liver disease. Subsequent studies with other lactic acid bacteria seem to demonstrate suppression of inflammation and one study also provides evidence of clinical improvement.

    Liver scintigraphy was performed using a newly developed radiopharmaceutical, Tc-99m-DTPA-galactosyl-human-serum-albumin (Tc-99m-GSA), which binds specifically to the receptors on the hepatic cell surface, in 15 patients with chronic liver disease. The scintigraphy was evaluated qualitatively and quantitatively, and the results were compared with those obtained from the Tc-99m-PMT or Tc-99m-sn-phytate scintigraphy, and the liver function tests. The Tc-99m-GSA scintigraphy showed clear liver images in chronic hepatitis. However, in liver cirrhosis, the liver images were not clear and the cardiac images still existed 40 minutes after administration of Tc-99m-GSA, suggesting that the image quality of the Tc-99m-GSA scintigrams may be inferior to that of Tc-99m-sn-phytate or Tc-99m-PMT in some cases of severe liver dysfunction. The time-activity curves of the heart and liver were analyzed by non-linear regression analysis. The clearance rate from plasma (Kd) were obtained from the time-activity curve of the heart, and the hepatic uptake rate (Ku), hepatic excretion rate (Ke) and peak time of hepatic uptake-excretion curve (PT) were obtained from the time-activity curve of the liver. Kd, Ku, and PT values were more significantly decreased or prolonged in the patients with chronic hepatitis. Kd, Ku, and PT values had positive correlations with the result of the serum liver function tests, ICG-R15 and ICG-K. Ku and PT values had also correlations with the histological degree of hepatic fibrosis. On the other hand, the indices obtained using Tc-99m-PMT or Tc-99m-sn-phytate did not have correlations with the histological degrees of hepatic fibrosis. It is concluded that the liver scintigraphy using Tc-99m-GSA may be useful and give different information from those with conventional liver scintigraphies in evaluating chronic liver diseases.

    Chronic subdural hematoma (cSDH) is a common neurosurgical ailment, particularly in elderly patients. A recent study uncovered an association between liver disease and recurrence in patients with cSDH. Here, we explored that relationship to identify recurrence predictors in at-risk patients. We hypothesized that the association between liver disease and recurrence was attributable to coagulopathy secondary to liver disease. We retrospectively reviewed all patients with cSDH treated with burr-hole drainage by 2 surgeons between 2007 and 2015. Comorbidities and laboratory findings for each patient were examined by Pearson χ 2 analysis or Mann-Whitney U tests. We identified 261 cSDH in 215 patients. Patients were a mean age of 65.6 years, and 72% were male. Sixteen patients with cSDH required repeat surgery (6.1%). There were 123 coagulopathic patients (47.1%), and 14 with liver disease (5.4%), all of whom were coagulopathic (P < 0.001). Coagulopathic patients with liver disease were more likely to experience recurrence than patients with coagulopathy alone (relative risk = 4.09, P = 0.019). Patients with liver disease had significantly elevated prothrombin time (P = 0.013) and reduced platelet counts (P < 0.001). Platelets also were reduced in coagulopathic patients with liver disease, as compared with those with coagulopathy alone (P = 0.002). Thrombocytopenia remained significant in a multivariate analysis (P < 0.001). Liver disease is significantly associated with the recurrence of cSDH. Although coagulopathy alone does not predict recurrence, patients with coagulopathy and liver disease are at greater risk for recurrence than those with coagulopathy alone. Liver disease effects are reflected in certain hematologic laboratory values. Copyright © 2017 Elsevier Inc. All rights reserved.

    The substantial heterogeneity and hierarchical organization in liver cancer support the theory of liver cancer stem cells (LCSCs). However, the relationship between chronic hepatic inflammation and LCSC generation remains obscure. Here, we observed a close correlation between aggravated inflammation and liver progenitor cell (LPC) propagation in the cirrhotic liver of rats exposed to diethylnitrosamine. LPCs isolated from the rat cirrhotic liver initiated subcutaneous liver cancers in nonobese diabetic/severe combined immunodeficient mice, suggesting the malignant transformation of LPCs toward LCSCs. Interestingly, depletion of Kupffer cells in vivo attenuated the LCSC properties of transformed LPCs and suppressed cytokeratin 19/Oval cell 6-positive tumor occurrence. Conversely, LPCs cocultured with macrophages exhibited enhanced LCSC properties. We further demonstrated that macrophage-secreted tumor necrosis factor-α triggered chromosomal instability in LPCs through the deregulation of ubiquitin D and checkpoint kinase 2 and enhanced the self-renewal of LPCs through the tumor necrosis factor receptor 1/Src/signal transducer and activator of transcription 3 pathway, which synergistically contributed to the conversion of LPCs to LCSCs. Clinical investigation revealed that cytokeratin 19/Oval cell 6-positive liver cancer patients displayed a worse prognosis and exhibited superior response to sorafenib treatment. Our results not only clarify the cellular and molecular mechanisms underlying the inflammation-mediated LCSC generation but also provide a molecular classification for the individualized treatment of liver cancer.

  12. Silymarin/Silybin and Chronic Liver Disease: A Marriage of Many Years

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available Silymarin is the extract of Silybum marianum, or milk thistle, and its major active compound is silybin, which has a remarkable biological effect. It is used in different liver disorders, particularly chronic liver diseases, cirrhosis and hepatocellular carcinoma, because of its antioxidant, anti-inflammatory and antifibrotic power. Indeed, the anti-oxidant and anti-inflammatory effect of silymarin is oriented towards the reduction of virus-related liver damages through inflammatory cascade softening and immune system modulation. It also has a direct antiviral effect associated with its intravenous administration in hepatitis C virus infection. With respect to alcohol abuse, silymarin is able to increase cellular vitality and to reduce both lipid peroxidation and cellular necrosis. Furthermore, silymarin/silybin use has important biological effects in non-alcoholic fatty liver disease. These substances antagonize the progression of non-alcoholic fatty liver disease, by intervening in various therapeutic targets: oxidative stress, insulin resistance, liver fat accumulation and mitochondrial dysfunction. Silymarin is also used in liver cirrhosis and hepatocellular carcinoma that represent common end stages of different hepatopathies by modulating different molecular patterns. Therefore, the aim of this review is to examine scientific studies concerning the effects derived from silymarin/silybin use in chronic liver diseases, cirrhosis and hepatocellular carcinoma.

    The main aim of the study is to study the clinical profile of disorders of the liver and hepatobiliary system in paediatric patients and to correlate the histopathology findings of liver biopsy in chronic liver disease. Another aim being to assess the prognosis and to know the outcome and the effects of treatment in chronic liver diseases in paediatric age group. It was a prospective study, included the clinical profile of Chronic Liver Diseases (CLD) in children and the histopathological correlation. A total of 55 children were thoroughly investigated by doing relevant investigations and liver biopsy. A male predominance (60%) was noted with maximum incidence in the age group of 6-12 years. The incidence of CLD was 1.1% of total admissions. The most common presenting complaint was jaundice and abdominal distension. Hepatic encephalopathy was noted in 29% patients. Hepatomegaly was seen in 63% patients and spleenomegaly was seen in 60% patients. The incidence of cirrhosis on liver biopsy was 42% (23cases) in CLD patients. The most common diagnosis on histopathology was Wilson's disease (22%), followed by hepatitis and autoimmune hepatitis. The predominant spectrum of CLD was metabolic liver disease and also the predominant cause of death. As the incidence of CLD is quite low, a very high index of suspicion is required for its diagnosis. Some uncommon causes of CLD in children were seen in our study like neutral lipid storage disease, α1-Antitrypsin deficiency disease, lupus hepatitis, Alagille syndrome and Budd-Chiari syndrome. A patient of CLD with jaundice and hepatomegaly should be treated aggressively as those are the poor prognostic indicators of the disease. Hepatic encephalopathy and cirrhosis are also associated with poor outcome in patients with CLD. Liver biopsy histopathology by an expert and its correlation with laboratory investigations plays an important role in the diagnosis of CLD. The major cause of deaths in patients with CLD is due to end stage

    To evaluate the prevalence and clinical profile of autoimmune hepatitis (AIH) in patients with chronic liver disease. Four hundred and thirty five consecutive patient with chronic liver disease seen in our department from January 1997 to December 1998 were studied with detailed history and clinical examination. All the patients underwent liver function tests, ultrasonography, isotope liver scanning, viral markers, autoimmune markers ANA, ASMA, LKM1 and AMA (by immunofluorescence technique) and liver histology whenever permissible. Appropriate work up for Wilson's disease was done whenever suspected clinically. Diagnosis of autoimmune hepatitis was made by the composite scoring system by international autoimmune hepatitis group. Twenty out of the 435 patients met the criteria of definite autoimmune hepatitis and seven patient had probable autoimmune hepatitis. Forty out of 408 patients showed markers of autoimmunity positive but did not qualify diagnosis of AIH on composite scores. Demographic profile of 27 patients with autoimmune hepatitis was as follows; male:female ratio 1:8, mean age 39.8 +/- 13 years (Range 4-65 years); mode of presentation as cirrhosis 11/27 (40.7%), chronic hepatitis 12/27 (44.4%) and acute hepatitis 4/27 (14.8%). Elevated serum bilirubin levels were seen in 12 (44.4%) patients while mean serum aminotransferases levels were 249 +/- 343 and 262 +/- 418 respectively. Other disease associations seen were as follows: diabetes in 4 (14.8%), rheumatoid arthritis in 3 (11%), hypothyroidism in 2 (7.4%) and ulcerative colitis in 1 (3.7%). The pattern of autoimmune markers was ANA +ve 23/27 (85%) (+ve titres of ANA > 1:80 in adults and 1:20 in children), ASMA +ve in 16/27 (59.2%) (+ve titres of ASMA > 1:40) and LKM1 in 3 patients. AMA in tires less than 1:80 was found in 3 patients. Liver histology changes seen were lymphoplasmacytic infiltrates (100%), bridging necrosis (93%), liver cell rossetting (80%) and fibrosis with or without cirrhosis (50

    The aim of this study was to determine the clinical performances of noninvasive serum markers for the prediction of liver fibrosis in chronic viral liver diseases. We analyzed a total of 225 patients with chronic viral liver diseases (180 with hepatitis B virus, 43 with hepatitis C virus, and 2 with hepatitis B+C virus) who underwent a liver biopsy procedure at the Hanyang University Guri Hospital between March 2002 and February 2007. Serum was also obtained at the time of liver biopsy. Liver fibrosis was staged according to the scoring system proposed by the Korean Study Group for the Pathology of Digestive Diseases. Various noninvasive serum markers were evaluated, including the aspartate aminotransferase (AST)/alanine aminotransferase (ALT) ratio (AAR), age-platelet (AP) index, AST/platelet ratio index (APRI), cirrhosis discriminant score (CDS), platelet count, hyaluronic acid (HA), and type IV collagen. There were 17, 40, 61, 74, and 33 patients at stages F0, F1, F2, F3, and F4, respectively. The overall diagnostic accuracies of each marker, as determined by the area under receiver operating characteristics curves, were APRI=0.822, CDS=0.776, platelet count=0.773, AP index=0.756, HA=0.749, type IV collagen=0.718, and AAR=0.642 for predicting significant fibrosis (> or =F2); and CDS=0.835, platelet count=0.795, AP index=0.794, HA=0.766, AAR=0.711, type IV collagen=0.697, and APRI=0.691 for predicting extensive fibrosis (> or =F3). All noninvasive serum markers evaluated in this study were useful for predicting significant or extensive liver fibrosis in chronic viral liver diseases. In particular, APRI was most useful for the prediction of significant fibrosis, and CDS was most useful for the prediction of extensive fibrosis.

    Many children with chronic liver disease require a liver transplant. These patients are prone to various infections, including Epstein-Barr virus infection. This study sought to measure the Epstein-Barr viral load by polymerase chain reaction before a liver transplant. This cross-sectional study was done at the Shiraz University of Medical Sciences, Shiraz, Iran, in 2011. All patients were aged younger than 18 years with chronic liver disease and were candidates for a liver transplant at the Shiraz Nemazee Hospital Organ Transplant Center. They had been investigated regarding their demographic characteristics, underlying disease, laboratory findings, and Epstein-Barr viral load by real-time TaqMan polymerase chain reaction. Ninety-eight patients were studied and the mean age was 6.5 ± 5.9 years. Cryptogenic cirrhosis was the most-prevalent reason for liver transplant, and the death rate before a transplant was 15%. Among the study subjects, 6 had measurable Epstein-Barr viral load by polymerase chain reaction before the transplant, and 4 of them had considerably higher Epstein-Barr viral loads (more than 1000 copies/mL). With respect to the close prevalence of posttransplant lymphoproliferative disease (6%) and the high Epstein-Barr viral load in the patients before a transplant (4%), high pretransplant Epstein-Barr viral load can be considered a risk factor for posttransplant lymphoproliferative disorder.

    BACKGROUND AND AIMS: Fatty liver is a common histological finding in human liver biopsy specimens. It affects 10-24% of the general population and is believed to be a marker of risk of later chronic liver disease. The present study examined the risk of development of cirrhotic liver disease...... and the risk of death in a cohort diagnosed with pure fatty liver without inflammation. METHODS: A total of 215 patients who had a liver biopsy performed during the period 1976-1987 were included in the study. The population consisted of 109 non-alcoholic and 106 alcoholic fatty liver patients. Median follow...... up time was 16.7 (0.2-21.9) years in the non-alcoholic and 9.2 (0.6-23.1) years in the alcoholic group. Systematic data collection was carried out by review of all medical records. All members of the study cohort were linked through their unique personal identification number to the National Registry...

    Full Text Available Total serum lipids, as well as apolipoproteins A-I (apo A-I and B (apo B, were determined in 74 patients with chronic liver failure without cholestasis and in 82 normal subjects. The VLDL, LDL and HDL lipid fractions were reduced in the liver failure group by 36%, 24% and 46%, respectively (P<0.001. Apolipoproteins A-I and B were also reduced by 26% and 25%, respectively (P<0.001. However, the reduction of HDL cholesterol (HDLc was more pronounced than that of apo A-I and the HDLc:apo A-I ratio was significantly lower in the liver failure group. After separating these patients into groups with plasma albumin lower than 3.0, between 3.0 and 3.5, and higher than 3.5 g/dl, the HDLc:apo A-I ratio was proportional to plasma albumin, but the correlation was not statistically significant. When these patients were separated by the Child classification of liver function, there was a correlation between the HDLc:apo A-I ratio and liver function. The differences in the HDLc:apo A-I ratio between the Child groups B and C, and A and C were statistically significant (P<0.05. We conclude that there is a more pronounced reduction in HDL cholesterol than in apo A-I in liver failure patients. Therefore, the HDLc:apo A-I ratio is a marker of liver function, probably because there is a decreased lecithin-cholesterol acyltransferase production by the diseased liver

    The metabolic changes compounded by anorexia associated with chronic liver disease adversely affect growth in children. In many cases, this requires the administration of artificial nutritional support. It is important in this group of patients that those who are becoming nutritionally depleted are identified quickly and in those receiving artificial nutritional support, the effectiveness is monitored. The current review is an examination of methods available to assess nutritional status. These include anthropometry, methods available in the laboratory and a selection of less commonly used methods undergoing evaluation at research level. A brief discussion accompanies each technique, outlining the limitations of its use in children with chronic liver disease. The review concludes with an outline of how nutritional status should be assessed in this group of children, and suggests further research.

  1. Hepatic encephalopathy in acute-on-chronic liver failure.

    2015-10-01

    The presence of hepatic encephalopathy (HE) within 4 weeks is part of the criteria for defining acute-on-chronic liver failure (ACLF). The pathophysiology of HE is complex, and hyperammonemia and cerebral hemodynamic dysfunction appear to be central in the pathogenesis of encephalopathy. Recent data also suggest that inflammatory mediators may have a significant role in modulating the cerebral effect of ammonia. Multiple prospective and retrospective studies have shown that hepatic encephalopathy in ACLF patients is associated with higher mortality, especially in those with grade III-IV encephalopathy, similar to that of acute liver failure (ALF). Although significant cerebral edema detected by CT in ACLF patients appeared to be less common, specialized MRI imaging was able to detect cerebral edema even in low grade HE. Ammonia-focused therapy constitutes the basis of current therapy, as in the treatment of ALF. Emerging treatment strategies focusing on modulating the gut-liver-circulation-brain axis are discussed.

    Objective: To detect serum MMP-13, TNF-α and IL-6 levels of the patients with chronic hepatitis B and liver cirrhosis, and evaluate their significant changes. To explore the correlation between serum TNF-α, IL-6 and MMP-13 levels. Method: Double antibody Sandwich Enzyme-Linked Immunosorbent Assay (DAS-ELISA) was used to detect chronic hepatitis in 13 cases, Liver cirrhosis in 28 cases and MMP-13 in the 13 controls, TNF-α in the 20 controls and IL-6 in the 30 controls. Results: Compared with the controls and chronic hepatitis, the serum MMP-13 levels of the patients with liver cirrhosis were significantly higher; the serum TNF-α and IL-6 levels of patients with chronic hepatitis as well as liver cirrhosis were significantly higher; the serum TNF-α and IL-6 levels did not relate to serum MMP-13 in patients with chronic hepatitis and liver cirrhosis. Conclusions: MMP-13 has important effect on formation of liver fibrosis. TNF-α and IL-6 have little effect on expression of MMP-13 levels of the patients with chronic hepatitis and liver cirrhosis.

    Background: Spontaneous bacterial peritonitis (SBP) is defined as infected ascites in the absence of any recognizable secondary cause of infection. Objectives: To find out the percentage of SBP in patients of chronic liver disease with ascites, its clinical and laboratory characteristics. Place and Duration of Study: Medical ward II, Jinnah Hospital Lahore and duration of study was six months. Study Design: Descriptive/ Observational study. Subjects and Method: One hundred patients of chronic liver disease with ascities were included in this study. Diagnostic paracentesis was performed immediately upon admission and the bacterial cultures and biochemical analysis was done on sample. Results: Ascitic fluid examination was the main basis for establishing the diagnosis of SBP. It was found that SBP was present in 22 patients, out of which 11 were culture positive and 11 were culture negative, 35 patients were HBsAg positive and 65 patients were anti HCV positive. SBP was found in 22 patients out of whom 10 were males and 12 females. Ascites was present in all the patients (100%). Shifting dullness was present in 76 (76%) cases, fluid thrill in 24 cases (24%) and tenderness in 47 patients (47%). Conclusion: Frequency of SBP is quite high in patients with chronic liver disease with ascites. SBP should be suspected in all such cases presenting with typical or atypical features. (author)

    Sarcopenia, a loss of muscle mass, is being increasingly recognized to have a deleterious effect on outcomes in patients with chronic liver disease. Factors related to diet and the inflammatory nature of chronic liver disease contribute to the occurrence of sarcopenia in these patients. Sarcopenia adversely influences quality of life, performance, morbidity, success of transplantation, and even mortality. Specific deficiencies in macronutrients (protein, polyunsaturated fatty acids) and micronutrients (vitamins C, D, and E, carotenoids, and selenium) have been linked to sarcopenia. Lessons learned from nutritional therapy in geriatric patient populations may provide strategies to manage sarcopenia in patients with liver disease. Combining diet modification and nutrient supplementation with an organized program of exercise may help ameliorate or even reverse the effects of sarcopenia on an already complex disease process.

    Hepatitis C and B virus (HCV, HBV) infection plays a crucial role in the etiology of chronic hepatitis, liver cirrhosis, and hepatocellular carcinoma, which have been reported to increase with radiation dose among the atomic bomb survivors. The purpose of this study is to investigate whether radiation exposure altered the prevalence of hepatitis virus infection or accelerated the progress toward chronic hepatitis after hepatitis virus infection. Levels of serum antibody to hepatitis C virus (anti-HCV), HBs antigen (HBsAg), and anti-HBs antibody (anti-HBs) were measured for 6,121 participants in the Adult Health Study of atomic bomb survivors in Hiroshima and Nagasaki. No relationship was found between anti-HCV prevalence and radiation dose, after adjusting for age, sex, city, history of blood transfusion, acupuncture, and family history, but prevalence of anti-HCV was significantly lower overall among the radiation-exposed people (relative prevalence 0.84, p=0.022) compared to people with estimated radiation dose 0 Gy. No significant interaction was found between any of the above mentioned risk factors and radiation dose. People with anti-HCV positive had 13 times higher prevalence of chronic liver disease than those without anti-HCV. However, the radiation dose response for chronic liver disease among anti-HCV positive survivors may be greater than that among anti-HCV negative survivors (slope ratio 20), but the difference was marginally significant (p=0.097). Prevalence of HBsAg increased with whole-body kerma. However, no trend with radiation dose was found in the anti-HBs prevalence. In the background, prevalence of chronic liver disease in people with HBsAg-positive was approximately three times higher that in those without HBsAg. No difference in slope of the dose was found among HBsAg positive and negative individuals (slope: HBsAg positive 0.91/Gy, HBsAg negative 0.11/Gy, difference p=0.66). In conclusion, no dose-response relationship was found between

    Hepatic fatty infiltration appears as an area of increased echogenicity. And many factors concerned to fatty infiltration. With 65 cases of fatty liver and 42 cases of normal group, we analyzed fatty liver with grading and attempt to find relations between grade of fatty liver and levels of body index, serum triglyceride, and serum lipid. And compared fatty liver with normal control group. Patients with fatty liver are higher percentage of supra-normal value in body index, serum lipid, and serum triglyceride than normal control group. As fatty infiltration progressed, serum lipid, serum trig-lyceride and body index are also increased. Conclusively ultrasonographic examination of liver with serum triglyceride, serum lipid, and body index are simple method, useful follow-up examination of fatty liver, and preventive routine check-up of chronic liver disease

    Twenty-four patients with chronic liver diseases and seven normal controls were studied using renal and hepatic radiotechnetium angiography. The time-activity histograms generated were employed to calculate both the renal perfusion index (RPI) and the hepatic perfusion index (HPI). Renal perfusion proved to be reduced not only in cirrhotic patients but also in patients with aggressive chronic hepatitis, as well as in those with persistent chronic hepatitis. The HPI, which is to be considered as being strictly dependent on portal flow, only fell significantly in the group of cirrhotic patients. In all patient groups, the correlation coefficient between the HPI and RPI (mean of the two kidneys) was low (r=0.275) and not significant (P>0.05). After Warren's splenorenal derivation, renal perfusion did not improve but worsened, particularly in the left kidney where derivation anastomosis probably caused a venous overload. (orig.)

  10. Chronic alcohol drinking: Liver and pancreatic cancer?

    Cancer is a multifactorial disease that results from complex interactions of numerous risk factors - genetic and environmental - over time, eventually leading to the diseased phenotypes. Thus, while epidemiological studies can point to risk factors, they cannot determine cause and effect relationships, and are unable to give biological and clinical insights into carcinogenesis. The link between any risk factor and carcinogenesis needs to be validated in experimental models. This is particularly true in epidemiological studies on alcohol consumption and its consequences. While there is no doubt that heavy alcohol consumption has devastating health effects, the inconsistencies in alcohol-related epidemiological studies and cancer suffer from possible sources of the variability in outcomes, ranging from inaccuracy of self-report of consumption to the problem of correlating cancer that started decades earlier to current or recent alcohol consumption. To further study the interactions between alcohol and cancer, the use of "Molecular Pathological Epidemiology" (MPE) advocated by Ogino et al. for dissecting the interplay between etiological factors, cellular and molecular characteristics, and disease progression in cancer is appropriate. MPE does not consider cancer as a single entity, rather it integrates analyses of epidemiological studies with the macroenvironment and molecular and microenvironment. This approach allows investigating the relationships between potential etiological agents and cancer based on molecular signatures. More research is needed to fully elucidate the link between heavy alcohol consumption and pancreatic cancer, and to further investigate the roles of acetaldehyde and FAEEs in pancreatic carcinogenesis.

    It has been postulated that the improved glucose tolerance provoked by chronic exercise is primarily attributable to increased insulin binding in skeletal muscle. Therefore, the authors investigated the effects of progressively increased training (6 wk) on insulin binding by five hindlimb skeletal muscles and in liver. In the trained animals serum insulin levels at rest were lower either in a fed or fasted state and after an oral glucose tolerance test. Twenty-four hours after the last exercise bout sections of the liver, soleus (S), plantaris (P), extensor digitorum longus (EDL), and red (RG) and white gastrocnemius (WG) muscles were pooled from four to six rats. Insulin binding to plasma membranes increased in S, P, and EDL but not in WG or in liver. There were insulin binding differences among muscles. Comparison of rank orders of insulin binding data with published glucose transport data for the same muscles revealed that these parameters do not correspond well. In conclusion, insulin binding to muscle is shown to be heterogeneous and training can increase insulin binding to selected muscles but not liver

    Background: Hepatitis B and C related chronic liver diseases have led to development of a serious threat to the people of South Asia. The main aim of this study was to evaluate the correlation of magnitude of arterial deoxygention to the severity of liver disease. Methods: It was a hospital based cross sectional descriptive study, carried out in the Medical Department of Khyber Teaching Hospital Peshawar. All in all 115 patients were assessed for the severity of the liver diseases and were correlated with arterial deoxygenation using linear regression models. Results: Male to female ratio was 1.5:1. Males infected with hepatitis B, hepatitis C and both were 9, 60 and 1, while females suffered from hepatitis B, Hepatitis C and both were 2, 42 and 1 respectively. The linear relationship between A-a DO2 with severity of liver disease showed positive correlation while PO2 showed negative correlation with severity of liver disease. Conclusion: There was a positive correlation between A-a DO2 and severity of liver diseases while PO2 and severity of liver diseases showed negative correlation. (author)

    To evaluate psychometrics of the Chinese (mainland) chronic liver disease questionnaire (CLDQ) in patients with chronic hepatitis B (CHB). A cross-sectional sample of 460 Chinese patients with CHB was selected from the Outpatient Department of the Eighth Hospital of Xi'an, including CHB (CHB without cirrhosis) (n = 323) and CHB-related cirrhosis (n = 137). The psychometrics includes reliability, validity and sensitivity. Internal consistency reliability was measured using Cronbach's α. Convergent and discriminant validity was evaluated by item-scale correlation. Factorial validity was explored by principal component analysis with varimax rotation. Sensitivity was assessed using Cohen's effect size (ES), and independent sample t test between CHB and CHB-related cirrhosis groups and between alanine aminotransferase (ALT) normal and abnormal groups after stratifying the disease (CHB and CHB-related cirrhosis). Internal consistency reliability of the CLDQ was 0.83 (range: 0.65-0.90). Most of the hypothesized item-scale correlations were 0.40 or over, and all of such hypothesized correlations were higher than the alternative ones, indicating satisfactory convergent and discriminant validity. Six factors were extracted after varimax rotation from the 29 items of CLDQ. The eligible Cohen's ES with statistically significant independent sample t test was found in the overall CLDQ and abdominal, systematic, activity scales (CHB vs CHB-related cirrhosis), and in the overall CLDQ and abdominal scale in the stratification of patients with CHB (ALT normal vs abnormal). The CLDQ has acceptable reliability, validity and sensitivity in Chinese (mainland) patients with CHB.

    BACKGROUND & AIMS: Activation of liver macrophages plays a key role in liver and systemic inflammation and may be involved in development and prognosis of acute-on-chronic liver failure (ACLF). We therefore measured the circulating macrophage activation markers soluble sCD163 and mannose receptor......-C ACLF and CLIF-C AD scores. Addition of the macrophage markers to the clinical scores improved the prognostic efficacy: In ACLF patients sCD163 improved prediction of short-term mortality (C-index: 0.74 (0.67-0.80)) and in patients without ACLF sMR improved prediction of long-term mortality (C-index: 0.......80 (0.76-0.85)). CONCLUSIONS: The severity related increase in sCD163 and sMR and close association with mortality suggest a primary importance of inflammatory activation of liver macrophages in the emergence and course of ACLF. Accordingly, supplementation of the macrophage biomarkers to the platform...

    Early diagnosis and treatment of the respiratory and gastrointestinal complications of cystic fibrosis (CF) have led to improved survival with many patients living beyond the fourth decade. Along with this increased life expectancy is the risk of further disease associated with the chronic manifestations of their condition. We report a patient with documented CF related liver disease for which he was under routine surveillance that presented with histologically proven hepatocellular carcinoma (HCC). It is important that physicians are aware of this association as increased vigilance may lead to earlier diagnosis and perhaps, a better outcome.

    Full Text Available The incidence of chronic hepatitis C in St. Petersburg is 124.4 per 100 000 population. The number of patients with liver cirrhosis is significant.Aim of this study: to examine the demographic, clinical and epidemiological characteristics of patients with cirrhosis in the results of chronic hepatitis C.Materials and methods: 100 patients with cirrhosis due to chronic hepatitis C in age 31–70 years were included. Patients with infection hepatitis viruses A and B, HIV, alcohol abuse, drug addicts, previously received antiviral therapy were excluded. Liver cirrhosis was diagnosed on the basis clinical, laboratory and instrumental investigations.Results: most patients (86,2% male and 81,7% female are socially adapted. In 23,2% of patients antibodies to hepatitis C virus were first detected simultaneously with the diagnosis of cirrhosis. Medical procedures were the most common route of infection (25,6% male and 57,1% female. Genotype 1 was dominant (65.7%. Viral load over 800 000 IU/ml was detected in 36,7% of patients. ALT activity was normal or not more than 2 upper limit of normal in 59% of patients, AST – 47%. Normal levels of total bilirubin were recorded in 37% of cases.Conclusions: the first detection of antibodies to hepatitis C virus at the stage of cirrhosis, absence of jaundice, normal or low cytolytic activity once again confirms the need for screening for markers of hepatitis C virus. Dominance of genotype 1 is probably due on the one hand with features routes of transmission, and the other – with the speed of transformation chronic hepatitis to cirrhosis.

    Full Text Available Introduction: Hepatitis B is one of the most frequent etiological factors for chronic liver diseases worldwide. Recent studies have suggested the important role of the genetic diversity of the virus on natural course of hepatitis B. Hepatitis B e-antigen negative type of chronic hepatitis is associated with mutations in the precore region and basic core promoter of hepatitis B viral genome. Aim of study was to identify precore mutations in viral genome of patients with chronic hepatitis B and to evaluate clinical patterns of liver disease related to this type of hepatitis B. Methods: Sixty seven patients with hepatitis B were included in the study. In order to evaluate the clinical patterns of chronic liver disease related to hepatitis B viral infection, biochemical and virological investigations were done, as well as a quantification of serum viral load. All patients underwent liver biopsy and semiquantification of necroinflammation and/or fibrosis according to Knodell scoring was done. In the group of e antigen-negative patients, molecular analysis was performed in order to identify presence of mutations in precore region of the virus. Results: Study group was divided in 25 HBeAg-positive and 42 HBeAg-negative subjects. Al anin-aminotransferase activity and level of viral load were higher in HBeAg-positive (p < 0.05, but average age and histology activity index were significantly higher in the HBeAg-negative patients (p < 0.01. Precore mutants were found in 38 of 42 patients with HBeAg-negative hepatitis (90%. Fibrosis was found in 30/38 cases with mutations. Discussion: Mutations in precore region of HBV in HBeAg-negative patients were more prevalent in older age and were associated with higher rate of fibrosis in liver tissue, meaning more advanced stage of the disease. This could be a consequence of longer duration of HBV infection or more severe clinical course of the disease. Conclusion: Our results suggest that precore mutations are

    Abnormal biliary secretion leads to the thickening of bile and the formation of plugs within the bile ducts; the consequent obstruction and abnormal bile flow ultimately results in the development of cystic fibrosis-related liver disease. This condition peaks in adolescence with up to 20% of adolescents with cystic fibrosis developing chronic liver disease. Early changes in the liver may ultimately result in end-stage liver disease with people needing transplantation. One therapeutic option currently used is ursodeoxycholic acid. This is an update of a previous review. To analyse evidence that ursodeoxycholic acid improves indices of liver function, reduces the risk of developing chronic liver disease and improves outcomes in general in cystic fibrosis. We searched the Cochrane CF and Genetic Disorders Group Trials Register comprising references identified from comprehensive electronic database searches, handsearches of relevant journals and abstract books of conference proceedings. We also contacted drug companies and searched online trial registries.Date of the most recent search of the Group's trials register: 09 April 2017. Randomised controlled trials of the use of ursodeoxycholic acid for at least three months compared with placebo or no additional treatment in people with cystic fibrosis. Two authors independently assessed trial eligibility and quality. The authors used GRADE to assess the quality of the evidence. Twelve trials have been identified, of which four trials involving 137 participants were included; data were only available from three of the trials (118 participants) since one cross-over trial did not report appropriate data. The dose of ursodeoxycholic acid ranged from 10 to 20 mg/kg/day for up to 12 months. The complex design used in two trials meant that data could only be analysed for subsets of participants. There was no significant difference in weight change, mean difference -0.90 kg (95% confidence interval -1.94 to 0.14) based on 30

    Patients with advanced liver disease have an increased risk of complications, compared to healthy patients when they undergo a surgical procedure. This risk is related to the type of surgery, to the type of anesthetic used, and to the severity of the underlying liver disease. Several risk factors for liver disease should be identified prior to a procedure. Those with advanced disease should undergo specific pre-surgical diagnostic tests. The Child Pugh score, and the MELD score, are very useful to establish the surgical risk in individuals with liver disease. The Child-Pugh score is a very useful tool that correlates closely to morbidity and mortality in patients with liver disease. Mortality rates in these patients undergoing major surgery is 10, 30 and 82% for Child-Pugh scores A, B and C respectively. In order to optimize the patient's condition before surgery, a complete evaluation and management of conditions such as jaundice, coagulopathy, ascites, electrolyte abnormalities, renal insufficiency and encephalopathy must be performed. This approach helps to reduce the complication rate in these individuals

    Hepatitis C infection is associated with autoimmune disorders, such as the production of autoantibodies. Anti-LKM1 and anti-LC1, immunomarkers of type 2 autoimmune hepatitis, have been previously associated with a HCV infection. Anti-Soluble-Liver-Antigen autoantibodies (SLA) are specifically associated with type 1 and type 2 autoimmune hepatitis and more closely related to patients who relapse after steroid therapy. The recent molecular cloning of the soluble liver antigen provides the opportunity to develop more specific tests for the detection of antibodies against it. The aim of this work is to characterize anti-soluble-liver autoantibodies in sera from patients chronically infected by HCV. A recombinant cDNA from activated Jurkat cells coding for the full length tRNP(Ser)Sec/SLA antigen was obtained. ELISA, Western Blot and immunoprecipitation tests were developed and used to search for linear and conformational epitopes recognized by anti-SLA antibodies in sera from patients chronically infected by HCV. Anti-soluble liver antigen antibodies were found in sera from 10.4% of HCV-infected patients. The prevalence was significantly increased to 27% when anti-LKM1 was also present. Most anti-SLA reactivity was directed against conformational epitopes on the antigen. The means titers by ELISA were lower than those obtained in type 2 AIH. The result of autoantibody isotyping showed a subclass restriction to IgG1 and also IgG4. This study shows the presence of anti-SLA antibodies in approximately 10% of HCV infected patients. The prevalence of SLA autoantibodies in HCV infected patients increases when LKM1 autoantibodies are also present. The relationship between the prevalence of this characteristic autoimmune hepatitis autoantibody and the implication of an autoimmune phenomenon in the liver injury of patients chronically infected by HCV needs further investigation.

    Chronic liver disease (CLD) is a common and expensive condition, and studies of CLD-related hospitalizations have underestimated the true burden of disease. We analyzed data from a large diverse healthcare system to compare time trends in CLD-related hospitalizations with those of congestive heart failure (CHF) or chronic obstructive pulmonary disease (COPD). We collected data from a large healthcare system in Texas on hospitalizations related to CLD (n=27,783), CHF (n=60,415), and COPD (n=34,199) from January 1, 2004 through December 31, 2013. We calculated annual hospitalization rates (per 100,000) and compared hospital course, inpatient mortality, ancillary services and re-admissions. Compared to patients with CHF (median age, 71 years) or COPD (median age 69 years), patients with CLD were significantly younger (median age 57 years; PCLD were uninsured (11.7% vs 5.4% for CHF and 5.4% for COPD; PCLD vs 9.3% for CHF and 5.0% for COPD; PCLD had Medicare (41.5% vs 68.6% with CHF and 70.1% with COPD; PCLD-related hospitalization increased by 92% (from 1295/100,000 to 2490/100,000), compared to 6.7% for CHF (from 3843/100,000 to 4103/100,000) and 48.8% for COPD (from 1775/100,000 to 2642/100,000). During this time period, CLD-related hospitalizations covered by Medicare increased from 31.8% to 41.5%, whereas hospitalizations covered by Medicare did not change for CHF (remained at 70%) or COPD (remained at 70%). Patients with CLD had longer hospital stays (7.3 days vs 6.2 days for CHF or 5.9 days for COPD; PCLD died or were discharged to hospice (14.2% vs 11.5% of patients with CHF and 9.3% of patients with COPD PCLD were readmitted to the hospital within 30 days (25% vs 21.9% of patients with CHF and 20.6% with COPD; PCLD.

    Full Text Available To investigate whether liver lobe based T2* values measured on gradient recalled echo T2*-weighted imaging are associated with the presence and Child-Pugh class of hepatitis B-related cirrhosis.Fifty-six patients with hepatitis B-related cirrhosis and 23 healthy control individuals were enrolled in this study and underwent upper abdominal T2*-weighted magnetic resonance imaging. T2* values of the left lateral lobe (LLL, left medial lobe (LML, right lobe (RL and caudate lobe (CL were measured on T2*-weighted imaging. Statistical analyses were performed to determine the association between liver lobe based T2* values and the presence and Child-Pugh class of cirrhosis.The T2* values of the LLL, LML and RL decreased with the progression of cirrhosis from Child-Pugh class A to C (r = -0.231, -0.223, and -0.395, respectively; all P 0.05. To a certain extent, Mann-Whitney U tests with Bonferroni correction for multigroup comparisons showed that the T2* values of the LLL, LML and RL could distinguish cirrhotic liver from healthy liver (all P 0.05. Receiver operating characteristic analysis demonstrated that the T2* value of the RL could best distinguish cirrhosis from healthy liver, with an area under the receiver operating characteristic curve (AUC of 0.713 among T2* values of the liver lobes, and that only the T2* value of the RL could distinguish Child-Pugh class C from A-B, with an AUC of 0.697 (all P < 0.05.The T2* value of the RL can be associated with the presence and Child-Pugh class of hepatitis B-related cirrhosis.

    341 patients with alcoholic disease of the liver were examined by means of hepatic scintigraphy with radiocolloids. 40 of them have abused with alcohol for up to 5 years, 97 - up to 10 years, 106 - up to 20 years, 50 - up to 30 years and 48 - more than 30 yeras. The following clinical diagnosis was defined: steatosis of the liver (85 cases), chronic alcoholic hepatitis (164 cases) and liver cirrhosis (92 cases). The diagnostic value of the hepatic scintigraphy for chronic alcoholic disease of the liver is stressed and its ability to precisize the extent of diffuse impairment of the liver parenchyma is illustrated by several cases discussed. The method possesses sufficient diagnostic potential for demonstration of liver cirrhosis. However, the scintigraphic findings are unsufficient for differentiation of the liver steatosis from the chronic alcoholic hepatitis

    Hepatic encephalopathy (HE) is a complex neuropsychiatric syndrome characterized by central neural depression which may develop in both acute and chronic liver diseases. Its pathogenesis is not clearly understood and its main cause(s) is not yet known. The relations between several cytokines and HE pathogenesis were evaluated in many studies. In this study, we aimed to investigate the role of TNF--α, IL-6 and IL-8 in the pathogenesis of HE . Furthermore, the relation between the severity of HE and the levels of these cytokines was assessted. Methods: fourty patients with liver cirrhosis [20 patients with clinical findings of HE (group 3) and 20 without any symptoms of HE (group 2)] and 20 healthy controls (group 1) were included in this study. Serum TNF--α, IL-6 and IL-8 levels of patients and control subjects were studied using competitive enzyme immunoassay method (EIA). Results: There were statistically significant difference between serum TNF--α. IL-6 and IL-8 levels of patients with liver cirrhosis and healthy subjects, and between patients with and without HE. There was a positive correlation between the severity of liver cirrhosis according to Child-Pugh classification and cytokine levels. The severity of HE (grade 1-4) was closely related with cytokine levels, especially TNF-α. On the other hand, there was no relation between cytokine levels and the etiological factors

    Mortality from chronic liver disease is rising exponentially. The liver is intimately linked to the gut via the portal vein, and exposure to gut microbiota and their metabolites translocating across the gut lumen may impact upon both the healthy and diseased liver. Modulation of gut microbiota could prove to be a potential therapeutic target. To characterise the changes in the gut microbiome that occur in chronic liver disease and to assess the impact of manipulation of the microbiome on the liver. We conducted a PubMed search using search terms including 'microbiome', 'liver' and 'cirrhosis' as well as 'non-alcoholic fatty liver disease', 'steatohepatitis', 'alcohol' and 'primary sclerosing cholangitis'. Relevant articles were also selected from references of articles and review of the ClinicalTrials.gov website. Reduced bacterial diversity, alcohol sensitivity and the development of gut dysbiosis are seen in several chronic liver diseases, including non-alcoholic fatty liver disease, alcohol-related liver disease and primary sclerosing cholangitis. Perturbations in gut commensals could lead to deficient priming of the immune system predisposing the development of immune-mediated diseases. Furthermore, transfer of stool from an animal with the metabolic syndrome may induce steatosis in a healthy counterpart. Patients with cirrhosis develop dysbiosis, small bowel bacterial overgrowth and increased gut wall permeability, allowing bacterial translocation and uptake of endotoxin inducing hepatic and systemic inflammation. Manipulation of the gut microbiota with diet, probiotics or faecal microbiota transplantation to promote the growth of "healthy" bacteria may ameliorate the dysbiosis and alter prognosis. © 2017 John Wiley & Sons Ltd.

    Full Text Available Abstract Background Acute-on-chronic liver failure (ACLF is a life threatening acute decompensation of a pre-existing chronic liver disease. The artificial liver support system MARS is a new emerging therapeutic option possible to be implemented in routine care of these patients. The medical efficacy of MARS has been demonstrated in first clinical studies, but economic aspects have so far not been investigated. Objective of this study was to estimate the cost-effectiveness of MARS. Methods In a clinical cohort trial with a prospective follow-up of 3 years 33 ACLF-patients treated with MARS were compared to 46 controls. Survival, health-related quality of life as well as direct medical costs for in- and outpatient treatment from a health care system perspective were determined. Based on the differences in outcome and indirect costs the cost-effectiveness of MARS expressed as incremental costs per life year gained and incremental costs per QALY gained was estimated. Results The average initial intervention costs for MARS were 14600 EUR per patient treated. Direct medical costs over 3 years follow up were overall 40000 EUR per patient treated with MARS respectively 12700 EUR in controls. The 3 year survival rate after MARS was 52% compared to 17% in controls. Kaplan-Meier analysis of cumulated survival probability showed a highly significant difference in favour of MARS. Incremental costs per life-year gained were 31400 EUR; incremental costs per QALY gained were 47200 EUR. Conclusion The results after 3 years follow-up of the first economic evaluation study of MARS based on empirical patient data are presented. Although high initial treatment costs for MARS occur the significantly better survival seen in this study led to reasonable costs per live year gained. Further randomized controlled trials investigating the medical efficacy and the cost-effectiveness are recommended.

    Malnutrition is commonly and frequently under-diagnosed in clinical settings in patients with chronic liver disease (CLD) due to the limitations of nutritional evaluation methods in this population. We hypothesized that the bioelectrical impedance analysis derived phase angle (BIA-derived PhA) might be considered as a nutritional indicator in CLD since it represents either cell death or malnutrition characterized by changes in cellular membrane integrity. The aim of this study was to evaluate the BIA-derived PhA as a nutritional evaluation tool in all stages of CLD, including chronic hepatitis, liver cirrhosis and hepatocellular carcinoma (HCC). Liver-related death and survival were evaluated. A total of 66 patients were enrolled in a cross-sectional study. For the nutritional diagnosis, mid-arm circumference (MAC), triceps skinfold thickness (TST), mid-arm muscle circumference (MAMC) and Subject Global Assessment (SGA) were evaluated. Biochemical and clinical evaluations were performed. Our results showed that PhA was higher in well-nourished patients, according to SGA and in the patients without hepatic encephalopathy. PhA correlated significantly with MAMC, MAC and albumin and was inversely correlated with age. No correlation was found between PhA values and the Child-Pugh score and ascites. PhA was strongly associated with survival and PhA ≤ 5.18º with relative risk increase of 2.5 for death. We conclude that the BIA-derived PhA is a relevant nutritional evaluation tool in chronic hepatitis, liver cirrhosis and HCC and the role of PhA in the prediction of survival in CLD should be examined further in a controlled study.

    Liver mortality among individuals with chronic hepatitis C (CHC) infection is common, but the relative contribution of CHC per se versus adverse health behaviours is uncertain. We explored data on spontaneous resolvers of hepatitis C virus (HCV) as a benchmark group, to uncover the independent...... contribution of CHC on liver mortality. Using national HCV diagnosis and mortality registers from Denmark and Scotland, we calculated the liver mortality rate (LMR) for persons diagnosed with CHC infection (LMRchronic ) and spontaneously resolved infection (LMRresolved ), according to subgroups defined by: age...

    The aim of the study was to identify the prevalence of HFE gene mutations in Czech patients with chronic liver diseases and the influence of the mutations on iron status. The presence of HFE gene mutations (C282Y, H63D, and S65C) analyzed by the PCR-RFLP method, presence of cirrhosis, and serum iron indices were compared among 454 patients with different chronic liver diseases (51 with chronic hepatitis B, 122 with chronic hepatitis C, 218 with alcoholic liver disease, and 63 patients with hemochromatosis). Chronic liver diseases patients other than hemochromatics did not have an increased frequency of HFE gene mutations compared to controls. Although 33.3% of patients with hepatitis B, 43% of patients with hepatitis C, and 73.2% of patients with alcoholic liver disease had elevated transferrin saturation or serum ferritin levels, the presence of HFE gene mutations was not significantly associated with iron overload in these patients. Additionally, patients with cirrhosis did not have frequencies of HFE mutations different from those without cirrhosis. This study emphasizes the importance, not only of C282Y, but also of the H63D homozygous genetic constellation in Czech hemochromatosis patients. Our findings show that increased iron indices are common in chronic liver diseases but {\\it HFE} mutations do not play an important role in the pathogenesis of chronic hepatitis B, chronic hepatitis C, and alcoholic liver disease.

    Liver and spleen volume were measured by computed tomography (CT) using point counting technique. This method is very simple and applicable to any kind of CT scanner. The volumes of the livers and spleens estimated by this method correlated with the weights of the corresponding organs measured on autopsy or surgical operation, indication the accuracy and usefulness of this method. Hepatic and splenic volumes were estimated by this method in 48 patients with chronic liver disease and 13 subjects with non-hepatobiliary discase. The mean hepatic volume in non-alcoholic liver cirrhosis but not in alcoholic cirrhosis was significantly smaller than those in non-hepatobiliary disease and other chronic liver diseases. Alcoholic cirrhosis showed significantly larger liver volume than non-alcoholic cirrhosis. In alcoholic fibrosis, the mean hepatic volume was significantly larger than non-hepatobiliary disease. The mean splenic volumes both in alcoholic and non-alcoholic cirrhosis were significantly larger than in other disease. A significantly positive correlation between hepatic and splenic volumes was found in alcoholic cirrhosis but not in non-alcoholic cirrhosis. These results indicate that estimation of hepatic and splenic volumes by this method is useful for the analysis of the pathophysiology of chronic liver disease. (author)

    To investigate the burden and recent epidemiological changes of the main chronic liver diseases in a Greek referral tertiary centre. We evaluated the main epidemiological characteristics of 1080 consecutive adult patients, seen at our outpatient liver clinic between 2002 and 2007, with chronic hepatitis B (HBV) and/or C (HCV) virus infection, alcoholic liver disease (ALD) or nonalcoholic fatty liver disease (NAFLD). Our patient population was divided into two groups in relation to the time of the first visit (period A: 2002-2004, period B: 2005-2007). Among our patient population, 86.1% had chronic HBV and/or HCV infection (chronic HCV alone: 44.9%), 9.2% NAFLD and 4.8% ALD. From period A to B, there was a decrease in chronic HBV cases (44.0 vs. 37.8%, P = 0.045) with immigrants being responsible for 35.5% of them and being more frequent in period B than A (39.7 vs. 30.5%, P = 0.046). In chronic hepatitis B, hepatitis B e antigen-positive patients, who were more frequent immigrants compared with hepatitis B e antigen-negative patients (65.5 vs. 29.5%, P = 0.001), increased from period A to B (8.0 vs. 17.6%, P = 0.045). Intravenous drug use was reported by 41.2% of HCV patients with its proportion increasing from period A to B (32.5 vs. 47.4%, P = 0.002). Decompensated cirrhosis was present in 67, 10, 11 and 3% of patients with ALD, HBV, HCV and NAFLD, respectively. At Greek tertiary centres, chronic viral hepatitis remains responsible for most chronic liver disease cases, but its epidemiology is changing owing to immigrants and intravenous drug users.

    Full Text Available Introduction: It is long known that vitamin D deficiency was common in patients with liver disease, but little is known on the therapeutic effects of vitamin D, especially in patients with chronic liver disease. In this study, we aimed to systematically review the literatures and study the evidences in which the effects of vitamin D supplementation had been investigated on the severity of chronic liver disease or liver cirrhosis.Methods: A systematic literature search was performed by using the following key terms “vitamin D supplementation” and “chronic liver disease” in the PubMed, Scopus and Google scholar to find relevant articles. After collecting the eligible documents, data were extracted and described based on the purpose of this review.Result: Of total 196 articles found, only 7 relevant documents with 518 studied patients were included. The results of this study showed that the levels of 25(OH D were considerably lower in patients with chronic liver disease. Findings showed that vitamin D supplementation can rise up the mean serum level of 25(OH D in patients with severe vitamin D deficiency, especially patients with liver cirrhosis.Conclusion:The results of this review showed that vitamin D deficiency is associated with the severity of liver disease and may have prognostic value in the assessment of liver disease. Also, it was shown that vitamin D supplementation may be helpful for the treatment of liver disease at least in certain groups of patients.

    To correlate serologic test and pathologic findings with change of hepatic parenchymal echogenicity on ultrasound (US) in patients with chronic renal failure. From January 1995 to April 2000, among eight hundred eighty four patients with kidney transplantation due to chronic renal failure, sixty seven patients who underwent US-guided liver biopsy were selected. Change of liver echogenicity on US was analyzed, and this change was compared with serologic test and pathologic findings. Among sixty seven patients, pathologic findings of thirty four patients with the normal liver echogenicity on US revealed normal in 15 patients (44%), viral hepatitis in 18 (53%), and liver cirrhosis in one patient (3%). Meanwhile, twenty seven patients with chronic liver disease on US were pathologically confirmed as normal in 13 patients (48%), viral hepatitis in 11 (40%), liver cirrhosis in four patients (11%); six patients with cirrhotic change on US, liver cirrhosis in four patients (67%) and viral hepatitis on two patients (33%). Serologic test of thirty four patients with the normal liver echogenicity on US showed positive HBs Ag in 17 patients (50%), positive anti-HCV Ab in 11 (32%), positive in both HBs Ag and anti-HCV Ab in one (3%), and normal result in five patients (15%). In patients with chronic renal failure, it is nor enough to determine the presence of liver disease only based on change of echogenicity on US. A careful correlation with serologic test and, if needed, pathologic confirmation are recommended for the accurate preoperative evaluation of the liver.

    Full Text Available Objective To investigate the effects of chronic intermittent hypoxia on the adipose factor and the expressions of insulin receptor substrate 2 (IRS-2, glucose transporter 2 (GLUT-2 and leptin in rat liver. Methods Twenty-four mature SD rats were randomly divided into 3 groups: control group (UC, chronic intermittent hypoxia group (CIH and reoxygenation group (RH. The arterial blood gas analysis was performed after the establishment of rat model. The serum fasting blood glucose (FBG and fasting insulin (FINS in each group were detected by peroxidase method; the concentrations of free fatty acids (FFA and leptin were detected by ELISA. The expressions of mRNA and protein of GLUT-2, IRS-2 and leptin were detected by qRT-PCR and Western blotting. Results The serous concentrations of FBG, FINS, FFA and leptin were significantly higher in CIH group than in UC group (P<0.05, and were dramatically higher in RH group than in both CIH group (P=0.003 and UC group (P=0.000. Western blotting and qRT-PCR detection showed that the protein and mRNA expressions of GLUT-2 and IRS-2 were significantly lower in CIH group than in RH group of rat liver (P<0.05, while were markedly lower in RH group than in UC group (P<0.05; the expressions of leptin protein and mRNA were significantly higher in CIH group than in RH group (P<0.05, while were obviously higher in RH group than in UC group of rat liver (P<0.05. Conclusion Insulin resistance induced by chronic intermittent hypoxia may be associated with the elevation of serum FFA and leptin, and be related to the decreased expression of GLUT-2 and IRS-2 and increased expression of leptin in liver.

    Objective: To evaluate the virological response to treatment with interferon and ribavirin in-patients with hepatitis C related liver disease. Material and Methods: Two hundred seventy-nine patients were included in the study. These patients had taken interferon and ribavirin treatment for HCV related chronic hepatitis, and were referred to AFIP for HCV RNA testing by polymerase chain reaction (PCR) between January 2002 and September 2002. Out of 279 cases, 229 had taken the treatment for 06 or 12 months and were tested for end-of-treatment response (ETR). Fifty patients had completed there treatment regimens of 6 or 12 months treatment, at least 24 weeks before their PCR test and were having follow-up testing for sustained viral response (SVR). The sera of these patients were tested for HCV RNA by PCR, using a commercial kit of Amplicor (Roche) for qualitative detection of HCV RNA. Results: Out of 229 cases tested for end-of-treatment response, 198 (86.5%) had no detectable HCV RNA (responders) and 31 (13.50%) were PCR positive (non-responders). Thirty-eight out of 50 cases, tested for a sustained viral response, had a negative result for HCV PCR thus showing sustained response rate of 76%. Conclusion: The viral remission/response to interferon and ribavirin combination therapy in our patients was better than that quoted in other regions. (author)

    Full Text Available Acute-on-chronic liver failure (ACLF is an acute deterioration of established liver disease. Blocking the TNF (tumor necrosis factor/TNFR (tumor necrosis factor receptor 1 pathway may reduce hepatocyte apoptosis/necrosis, and subsequently decrease mortality during development of ACLF. We demonstrated that a long-acting TNF antagonist (soluble TNF receptor: IgG Fc [sTNFR:IgG-Fc] prevented/reduced development of acute liver failure by blocking the TNF/TNFR1 (TNFRp55 pathway. However, it is still unclear if sTNFR:IgG-Fc can inhibit hepatocyte damage during development of ACLF.Chronic liver disease (liver fibrosis/cirrhosis was induced in Wistar rats by repeatedly challenging with human serum albumin (HSA, and confirmed by histopathology. ACLF was induced with D-galactosamine (D-GalN/lipopolysaccharide (LPS i.p. in the rats with chronic liver disease. Serum and liver were collected for biochemical, pathological and molecular biological examinations.Reduced mortality was observed in sTNFR:IgG-Fc treated ACLF rats, consistent with reduced interleukin (IL-6 levels in serum and liver, as well as reduced hepatic caspase-3 activity, compared to that of mock treated group. Reduced hepatic damage was confirmed with histopathology in the sTNFR:IgG-Fc treated group, which is consistent with reduced Bcl-2 and Bax, at mRNA and protein levels, but increased hepatocyte proliferation (PCNA. This is also supported by the findings that caspase-3 production was up-regulated significantly in ACLF group compared to the mock treated group. Moreover, up-regulated caspase-3 was inhibited following sTNFR:IgG-Fc treatment. Finally, there was up-regulation of hepatic IL-22R in sTNFR:IgG-Fc treated ACLF rats.sTNFR:IgG-Fc improved survival rate during development of ACLF via ameliorating liver injury with a potential therapeutic value.

  6. Associations between Zinc Deficiency and Metabolic Abnormalities in Patients with Chronic Liver Disease

    Directory of Open Access Journals (Sweden)

    2018-01-01

    Full Text Available Zinc (Zn is an essential trace element which has favorable antioxidant, anti-inflammatory, and apoptotic effects. The liver mainly plays a crucial role in maintaining systemic Zn homeostasis. Therefore, the occurrence of chronic liver diseases, such as chronic hepatitis, liver cirrhosis, or fatty liver, results in the impairment of Zn metabolism, and subsequently Zn deficiency. Zn deficiency causes plenty of metabolic abnormalities, including insulin resistance, hepatic steatosis and hepatic encephalopathy. Inversely, metabolic abnormalities like hypoalbuminemia in patients with liver cirrhosis often result in Zn deficiency. Recent studies have revealed the putative mechanisms by which Zn deficiency evokes a variety of metabolic abnormalities in chronic liver disease. Zn supplementation has shown beneficial effects on such metabolic abnormalities in experimental models and actual patients with chronic liver disease. This review summarizes the pathogenesis of metabolic abnormalities deriving from Zn deficiency and the favorable effects of Zn administration in patients with chronic liver disease. In addition, we also highlight the interactions between Zn and other trace elements, vitamins, amino acids, or hormones in such patients.

    Non-organ specific autoantibodies are highly prevalent in patients with chronic hepatitis C (HCV). Among them, anti-liver kidney microsomal type 1 (LKM1) antibody--the serological marker of type 2 autoimmune hepatitis (AIH-2)--is detected in up to 11% of the HCV-infected subjects. On the other hand, anti-liver cytosol type 1 antibodies (anti-LC1)--either in association with anti-LKM1, or in isolation--and anti-soluble liver antigen antibodies (anti-SLA) have been considered as useful and specific diagnostic markers for AIH. However, their specificity for AIH has been questioned by some recent studies, which have shown the detection of anti-LC1 and anti-SLA by immunoprecipitation assays in HCV patients irrespective of their anti-LKM1 status. The aim of the present study was to test the anti-LC1 and anti-SLA presence by specific enzyme linked immunosorbent assays (ELISAs), in a large group of Greek HCV-infected patients with or without anti-LKM1 reactivity as firstly, immunoprecipitation assays are limited to few specialized laboratories worldwide and cannot be used routinely and secondly, to assess whether application of such tests has any relevance in the context of patients with viral hepatitis since antibody detection based on such ELISAs has not been described in detail in large groups of HCV patients. One hundred and thirty eight consecutive HCV patients (120 anti-LKM1 negative and 18 anti-LKM1 positive) were investigated for the presence of anti-LC1 and anti-SLA by commercial ELISAs. A similar number (120) of chronic hepatitis B virus (HBV) infected patients seronegative for anti-LKM1 was also tested as pathological controls. Six out of 18 (33%) anti-LKM(pos)/HCV(pos) patients tested positive for anti-LC1 compared to 1/120 (0.83%) anti-LKM(neg)/HCV(pos) patients and 0/120 (0%) of the anti-LKM1(neg)/HBV(pos) patients (p LKM1) or HBV-infected patients. We showed that anti-LC1 and anti-SLA autoantibodies are not detected by conventional assays in a large group of

    To investigate pathological types and influential factors of chronic graft dysfunction (CGD) following liver transplantation (LT) in rats. The whole experiment was divided into three groups: (1) normal group (n = 12): normal BN rats without any drug or operation; (2) syngeneic transplant group (SGT of BN-BN, n = 12): both donors and recipients were BN rats; and (3) allogeneic transplant group (AGT of LEW-BN, n = 12): Donors were Lewis and recipients were BN rats. In the AGT group, all recipients were subcutaneously injected by Cyclosporin A after LT. Survival time was observed for 1 year. All the dying rats were sampled, biliary tract tissues were performed bacterial culture and liver tissues for histological study. Twenty-one day after LT, 8 rats were selected randomly in each group for sampling. Blood samples from caudal veins were collected for measurements of plasma endotoxin, cytokines and metabonomic analysis, and faeces were analyzed for intestinal microflora. During the surgery of LT, no complications of blood vessels or bile duct happened, and all rats in each group were still alive in the next 2 wk. The long term observation revealed that a total of 8 rats in the SGT and AGT groups died of hepatic graft diseases, 5 rats in which died of chronic bile duct hyperplasia. Compared to the SGT and normal groups, survival ratio of rats significantly decreased in the AGT group (P liver necrosis, liver infection, and severe chronic bile duct hyperplasia were observed in the AGT group by H and E stain. On 21 d after LT, compared with the normal group (25.38 ± 7.09 ng/L) and SGT group (33.12 ± 10.26 ng/L), plasma endotoxin in the AGT group was remarkably increased (142.86 ± 30.85 ng/L) (both P bile duct tissues revealed that the rats close to death from the SGT and AGT groups were strongly positive, while those from the normal group were negative. The analysis of intestinal microflora was performed. Compared to the normal group (7.98 ± 0.92, 8.90 ± 1.44) and SGT

    Alcoholic liver diseases often evolve to acute-on-chronic liver failure (ACLF), which increases the risk of (multi-)organ failure and death. We investigated the development and characteristics of alcohol-related ACLF and evaluated prognostic scores for prediction of mortality in Asian patients with active alcoholism. A total of 205 patients who were hospitalized with severe alcoholic liver disease were included in this retrospective cohort study, after excluding those with serious cardiovascular diseases, malignancy, or co-existing viral hepatitis. The Chronic Liver Failure (CLIF) Consortium Organ Failure score was used in the diagnosis and grading of ACLF, and the CLIF Consortium ACLF score (CLIF-C ACLFs) was used to predict mortality. Patients with ACLF had higher Maddrey discriminant function, model for end-stage liver disease (MELD), and MELD-sodium scores than those without ACLF. Infections were more frequently documented in patients with ACLF (33.3% vs 53.0%; P = 0.004). Predictive factors for ACLF development were systemic inflammatory response syndrome (odds ratio [OR], 2.239; P alcohol-related ACLF in Asian patients with active alcoholism. The CLIF-C ACLFs may be more useful for predicting mortality in ACLF cases than liver-specific scoring systems. © 2015 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

    KONG Degang

    2016-12-01

    Full Text Available Patients with liver fibrosis and cirrhosis experience certain changes in spleen morphology and function, and there is always a controversy over whether to perform splenectomy in patients with liver cirrhosis. As a surgical treatment of recurrent portal hypertension complicated by esophagogastric variceal bleeding, splenectomy can reduce portal venous pressure, reduce the possibility of gastrointestinal bleeding, and correct the reduced white blood cell count and platelet count. It can also protect the liver by improving liver function, promoting regeneration of hepatocytes, and inhibiting the progression of liver fibrosis. With reference to available clinical and laboratory data, this article reviews the effect of splenectomy on the cirrhotic liver and related issues such as selection of surgical procedures and prevention and treatment of postoperative complications, in order to promote splenectomy in patients with liver cirrhosis.

    Among 177 patients with chronic non-malignant liver disease, the prevalence of raised levels of alpha-fetoprotein (AFP) was 11.2 percent. A close association between the severity of the liver disease and AFP concentrations was observed. The most frequent pattern of hepatitis B virus (HBV) infection in these patients was the presence of antibodies to hepatitis B surface antigen (anti-HBs) and hepatitis B core antigen (anti-HBc), whilst only 5 cases were positive for hepatitis B surface antigen (HBsAg). Sixty seven patients, 18 of whom with high AFP, were longitudinally studied over a period ranging from 1 to 6 years. The evaluation of AFP was transient in 6 cases and persistent in 12 cases. The patients in the former group had high activity of liver disease and none of them developed primary liver cell cancer during the follow-up. In contrast, only two patients in the latter group had high activity, and 3 developed PLC. Active HBV replication was significantly more frequent among those with transient elevation of AFP, whereas anti-HBs and anti-HBc positive cases were significantly more frequent among those with persistent elevation of AFP. It is concluded that the severity of the liver disease is the major factor of elevation of AFP. Transiently raised levels of AFP are not related with PLC, whereas persistently high levels represent a premalignant condition. At variance with data obtained in areas with high prevalence of PLC, HBsAg seems not to be related with persistent elevation of AFP. The high rate positive for anti-HBs and anti-HBc in this group remains to be clarified

    Several noninvasive predictive models were developed to substitute liver biopsy for fibrosis assessment. To evaluate the diagnostic value of fibronectin which reflect extracellular matrix metabolism and standard liver functions tests which reflect alterations in hepatic functions. Chronic hepatitis C (CHC) patients (n = 145) were evaluated using ROC curves and stepwise multivariate discriminant analysis (MDA) and was validated in 180 additional patients. Liver biochemical profile including transaminases, bilirubin, alkaline phosphatase, albumin, complete blood count were estimated. Fibronectin concentration was determined using monoclonal antibody and ELISA. A novel index named fibronectin discriminant score (FDS) based on fibronectin, APRI and albumin was developed. FDS produced areas under ROC curves (AUC) of 0.91 for significant fibrosis and 0.81 for advanced fibrosis. The FDS correctly classified 79% of the significant liver fibrosis patients (F2-F4) with 87% sensitivity and 75% specificity. The relative risk [odds ratio (OR)] of having significant liver fibrosis using the cut-off values determined by ROC curve analyses were 6.1 for fibronectin, 4.9 for APRI, and 4.2 for albumin. FDS predicted liver fibrosis with an OR of 16.8 for significant fibrosis and 8.6 for advanced fibrosis. The FDS had similar AUC and OR in the validation group to the estimation group without statistically significant difference. FDS predicted liver fibrosis with high degree of accuracy, potentially decreasing the number of liver biopsy required.

    This study aimed to investigate the prevalence and incidence of chronic liver disease in patients with bipolar disorder. We used a random sample of 766,427 subjects aged ≥18 years from the National Health Research Institute database in the year 2005. Subjects with at least one primary diagnosis of bipolar disorder in 2005 were identified. Patients with a primary or secondary diagnosis of chronic liver disease were also defined. We compared the prevalence and associated factors of chronic liver disease between patients with bipolar disorder and the general population in 2005. We also compared the incidence of chronic liver disease in patients with bipolar disorder and the general population from 2006 to 2010. The prevalence of chronic liver disease in patients with bipolar disorder (13.9%) was 2.68 times higher than that of the general population (5.8%) in 2005. The average annual incidence of chronic liver disease in patients with bipolar disorder from 2006 to 2010 was also higher than that of the general population (2.95% vs. 1.73%; risk ratio: 1.71; 95% confidence interval: 1.46-2.01). Patients with bipolar disorder had a significantly higher prevalence and incidence of chronic liver disease than those in the general population, and younger patients with bipolar disorder have a much higher prevalence and incidence than those in the general population. Male sex, second-generation antipsychotic or antidepressant use, and hyperlipidemia were associated factors for chronic liver disease in patients with bipolar disorder. Copyright © 2016 Elsevier Inc.

  19. Serum 1H-NMR metabolomic fingerprints of acute-on-chronic liver failure in intensive care unit patients with alcoholic cirrhosis.

    Directory of Open Access Journals (Sweden)

    Roland Amathieu

    Full Text Available INTRODUCTION: Acute-on-chronic liver failure is characterized by acute deterioration of liver function in patients with compensated or decompensated, but stable, cirrhosis. However, there is no accurate definition of acute-on-chronic liver failure and physicians often use this term to describe different clinical entities. Metabolomics investigates metabolic changes in biological systems and identifies the biomarkers or metabolic profiles. Our study assessed the metabolomic profile of serum using proton nuclear magnetic resonance ((1H-NMR spectroscopy to identify metabolic changes related to acute-on-chronic liver failure. PATIENTS: Ninety-three patients with compensated or decompensated cirrhosis (CLF group but stable liver function and 30 patients with cirrhosis and hospitalized for the management of an acute event who may be responsible of acute-on-chronic liver failure (ACLF group, were fully analyzed. Blood samples were drawn at admission, and sera were separated and stored at -80°C until (1H-NMR spectral analysis. Using orthogonal projection to latent-structure discriminant analyses, various metabolites contribute to the complete separation between these both groups. RESULTS: The predictability of the model was 0.73 (Q(2 Y and the explained variance was 0.63 (R(2 Y. The main metabolites that had increased signals related to acute-on-chronic liver failure were lactate, pyruvate, ketone bodies, glutamine, phenylalanine, tyrosine, and creatinine. High-density lipids were lower in the ALCF group than in CLF group. CONCLUSION: A serum metabolite fingerprint for acute-on-chronic liver failure, obtained with (1H-NMR, was identified. Metabolomic profiling may aid clinical evaluation of patients with cirrhosis admitted into intensive care units with acute-on-chronic liver failure, and provide new insights into the metabolic processes involved in acute impairment of hepatic function.

    in patients with alcoholic cirrhosis. This decrease seems to be due to decreased liver function, decreasing hepatic blood flow, and increased portosystemic shunting. Oral testosterone loading may therefore be of prognostic significance in patients with alcoholic liver cirrhosis.......The relation between liver function and an oral testosterone load was examined in 42 consecutive patients with alcoholic liver cirrhosis. Administration of an oral load of 400 mg micronized free testosterone increased the serum concentration of testosterone (range, 31.9-694.4 nmol/l; median, 140.......8 nmol/l) in male patients with alcoholic liver cirrhosis to significantly (P less than 0.01) higher levels than in male subjects without liver disease (range, 25.4-106.6 nmol/l; median, 61.5 nmol/l). The increase of testosterone after the load (log delta testosterone) in patients correlated inversely...

    There is a worldwide problem of acute liver failure and mortality associated with remaining on the waiting for a liver transplant. In this study, we highlight results published in recent years by leading transplant centers in evaluating imatinib-induced acute liver failure in chronic myeloid leukemia and follow-up in liver transplantation. A 36-year-old brown-skinned woman (mixed Brazilian race) diagnosed 1 year earlier with chronic myeloid leukemia was started after delivery of a baby and continued for 6 months with imatinib mesylate (selective inhibitor of Bcr-Abl tyrosine kinase), which induced liver failure. We conducted a literature review using the PubMed database for articles published through September 2017, and we demonstrate a role of liver transplant in this situation for imatinib-induced liver failure. We report previously published results and a successful liver transplant after acute liver failure due to imatinib-induced in chronic myeloid leukemia treatment. We report a case of a successful liver transplant after acute liver failure resulting from imatinib-induced chronic myeloid leukemia treatment. The literature reveals the importance of prompt acute liver failure diagnosis and treatment with liver transplant in selected cases.

    Occult hepatitis B infection (OBI) may adversely affect the outcome of patients with chronic liver disease (CLD). There are no data on OBI and CLD in children. This study determined the prevalence and effect of OBI in HBsAg-negative CLD children. CLD children were prospectively evaluated with a demographic, clinical, and investigative proforma. All HBsAg-negative CLD cases were tested for exposure to hepatitis B (total anti-HBc, anti-HBs). Serum hepatitis B virus DNA was measured in exposed (total anti-HBc positive) patients. A total of 115 HBsAg-negative CLD children (59 boys, age 9.0±3.6 years) were enrolled. The etiology of CLD was known in 94 cases and 21 children had cryptogenic CLD. Of these, 45 (39.1%) had evidence of HBV exposure (23 total anti-HBc positive, 17 total anti-HBc and anti-HBs positive, five only anti-HBs positive without previous vaccination). The anti-HBc-positive children had a higher Child's score than the anti-HBc-negative children [11 (5-13) vs. 7 (5-13); P=0.00]. A total of 4/45 children had seropositive OBI with serum HBV DNA of 8, 36, 133, and 156 IU/ml, respectively. The proportion of total anti-HBc positivity (8/21 vs. 32/94; P=0.8) and OBI (2/21 vs. 2/94; P=0.1) was similar in cryptogenic CLD and known cause CLD. Seropositive OBI is infrequent in Indian children with CLD. The prevalence is similar in cryptogenic and CLD of known etiology.

    Highlights: • Three US parameters have diagnosis accuracy for the diagnosis of severe fibrosis equal to 66%. • These three signs detect unidentified fibrosis with a predictive positive value of 32%. • It would be an easy way to detect patients with silent chronic liver diseases. - Abstract: Objectives: Chronic liver diseases remain asymptomatic for many years. Consequently, patients are diagnosed belatedly, when cirrhosis is unmasked by lifethreatening complications. We aimed to identify simple ultrasound parameters for the screening of patients with unknown significant chronic liver disease. Methods: Three hundred and twenty seven patients with chronic liver disease, liver biopsy, and ultrasound examination were included in the derivation set. 283 consecutive patients referred for ultrasound examination were included in the validation set; those selected according to the ultrasound parameters identified in the derivation set were then referred for specialized consultation including non-invasive fibrosis tests and ultimately liver biopsy if liver fibrosis was suspected. Results: In the derivation set, three ultrasound parameters were independent predictors of severe fibrosis: liver surface irregularity, spleen length (>110 mm), and demodulation of hepatic veins. The association of ≥2 of the three above parameters provided 49.1% sensitivity and 86.9% specificity. In the validation set, at ≥2 of the three parameters were present in 23 (8%) of the patients. Among these patients, 8 had liver fibrosis (F ≥ 1), 5 had significant fibrosis (F ≥2) and two cirrhosis. Conclusion: The generalized search of three simple ultrasound signs in patients referred for abdominal ultrasound examination may be an easy way to detect those with silent but significant chronic liver disease

    Full Text Available The VEGF gene polymorphism rs699947 related to clinical pathology, mortality, and recurrence of HCC. Few studies mentioned an association between VEGF gene polymorphisms with illness progression in chronic liver disease. We aimed to explore differences of VEGF gene polymorphism rs699947 in chronic hepatitis, liver cirrhosis and hepatocellular carcinoma patients in Indonesian population.A cross-sectional study with consecutive sampling and without matching was performed during a 3 years period (2011-2014 at Dr. Sardjito General Hospital Yogyakarta, Indonesia. Blood DNA was sequenced from 123 subjects with chronic liver diseases [39 chronic hepatitis (CH, 39 liver cirrhosis (LC, and 45 hepatocellular carcinoma (HCC]. 59 healthy subjects also participated. Using isolated VEGF genes for specific primers for rs699947, blood samples were examined by targeting DNA sequences with Applied Bio systems. All data were analyzed using STATA version 11.0 with significance level at P0.05. HBV was the dominant etiology in HCC, LC, and CH besides HCV and non HBV-HCV (PC vs. C>C, and genotypes distribution. Proportion of SNP -2578 A>C vs. C>C CH 1.8:1; HCC 1.4:1; healthy 1.7:1; but its proportion in LC was inversed (1:1.2. Genotype A was low in all subjects (5%-11%. Significant difference of allele distribution was found in healthy vs. LC, and HCC; CH vs. LC. Based on HWE analyses, distribution of allele C was dominant. There were not significant differences in deletion, insertion-deletion at -2547 until -2526, and haplotype (Ht CCGACCCC (P>0.05. The OR analyses of allele and SNP showed that allele A can be a predictor of disease progression in LC to HCC (OR 2.26 and healthy to LC (OR 1.65; and SNP A>C also can be a predictor in healthy to HCC (OR 1.41 and CH (OR 1.14.The occurrence of allele A and SNP A>C VEGF gene (-2578 might predict illness progression from healthy to CH, LC or HCC and LC to HCC.

    Full Text Available Cardiopulmonary resuscitation (CPR is recognized as a medical procedure performed to maintain vital functions of a person whose cardiac and respiratory functions have stopped. Chest compression is the most essential component of CPR and it is performed on the lower half of the sternum. During CPR, many complications may occur because of chest compressions, especially chest injuries including sternum and rib fractures. Rarely tracheal injury, rupture of the stomach, or liver or spleen injury may also occur as complications.In this study, we present two cases of liver injury caused by resuscitation. With this article, we want to emphasize the importance of making correct chest compressions. Keywords: Resuscitation complications, Emergency service, Liver laceration, Autopsy

    Background. Platelet to white blood cell ratio (PWR) was an independent prognostic predictor for outcomes in some diseases. However, the prognostic role of PWR is still unclear in patients with hepatitis B related acute-on-chronic liver failure (ACLF). In this study, we evaluated the clinical performances of PWR in predicting prognosis in HBV-related ACLF. Methods. A total of 530 subjects were recruited, including 97 healthy controls and 433 with HBV-related ACLF. Liver function, prothrombin time activity (PTA), international normalized ratio (INR), HBV DNA measurement, and routine hematological testing were performed at admission. Results . At baseline, PWR in patients with HBV-related ACLF (14.03 ± 7.17) was significantly decreased compared to those in healthy controls (39.16 ± 9.80). Reduced PWR values were clinically associated with the severity of liver disease and the increased mortality rate. Furthermore, PWR may be an inexpensive, easily accessible, and significant independent prognostic index for mortality on multivariate analysis (HR = 0.660, 95% CI: 0.438-0.996, p = 0.048) as well as model for end-stage liver disease (MELD) score. Conclusions . The PWR values were markedly decreased in ACLF patients compared with healthy controls and associated with severe liver disease. Moreover, PWR was an independent prognostic indicator for the mortality rate in patients with ACLF. This investigation highlights that PWR comprised a useful biomarker for prediction of liver severity.

    Salvatore Petta

    Full Text Available BACKGROUND AND AIMS: Serum levels of γ-glutamyl-transpeptidase(γ-GT were associated with liver disease severity and metabolic alterations, which in turn are able to affect hepatic damage. In patients with nonalcoholic fatty liver disease (NAFLD, genotype 1 chronic hepatitis C (G1CHC and chronic hepatitis B (CHB, we assessed the link between liver fibrosis and γ-GT serum levels, and we evaluated if normal or high γ-GT serum levels affect the association between insulin resistance (IR and severity of liver fibrosis. METHODS: 843 consecutive patients with chronic liver disease (CLD(193 NAFLD, 481 G1CHC, 169 CHB were evaluated by liver biopsy (Kleiner and Scheuer scores and clinical and metabolic measurements. IR was diagnosed if HOMA>3. A serum γ-GT concentration of >36 IU/L in females and >61 IU/L in males was considered the threshold value for identifying high levels of γ-GT. RESULTS: By multivariate logistic regression analysis, abnormal γ-GT serum levels were independently linked to severe liver fibrosis in patients with NAFLD (OR2.711,CI1.120-6.564,p = 0.02, G1CHC (OR3.461,CI2.138-5.603,p80%. Interestingly, among patients with high or normal γ-GT values, even if IR prevalence was significantly higher in patients with severe fibrosis compared to those without, IR remained significantly associated with severe fibrosis in patients with abnormal γ-GT values only (OR4.150,CI1.079-15.970,p = 0.03 for NAFLD; OR2.250,CI1.211-4.181,p = 0.01 for G1CHC; OR3.096,CI2.050-34.220,p = 0.01 for CHB. CONCLUSIONS: In patients with CLD, IR is independently linked to liver fibrosis only in patients with abnormal γ-GT values, without differences according to liver disease etiology, and suggesting a role of γ-GT as a marker of metabolic-induced liver damage. These data could be useful for the clinical and pharmacologic management of patients with CLD.

    Objective: To determine the causes, characteristics and predictors of mortality in patients with acute-on-chronic liver failure (ACLF). Study Design: Cross-sectional study. Place and Duration of Study:Department of Hepatogastroenterology, Sindh Institute of Urology and Transplantation, Karachi, from July 2014 to June 2016. Methodology:All patients with acute-on-chronic liver disease (ACLD) with ages > 12 were included. Patients with ACLF, as defined by the Asian Pacific Association for the Study of Liver (APASL, 2014) were identified. Predictors of mortality were identified using chi-square or Fisher's exact test. Results: Included in the study were 72 patients with mean age of 36.71 years, 46 (63.9%) being males. Among them, 61 developed ACLF. Commonest causes of chronic liver disease (CLD) were chronic viral hepatitis (37, 51.4%) and autoimmune hepatitis (14, 19.4%). Commonest causes of acute liver injury (ALI) were acute viral hepatitis (24, 33.3%) and drug induced liver injury (DILI) (17, 23.6%). Among those with ACLF, 24 (39.3%) patients died with median survival of 17.1 +-13.5 days. Mortality was significantly associated with Child Turcotte Pugh (CTP) score =>13 (p=0.010), model for end-stage liver disease (MELD) score =>30 (p=0.001), age >40 years (p=0.036), organ failures (OF) =>3 (p 3, CTP =>13, MELD =>30, age >40 years, PSE, renal failure and urosepsis.

    Chronic liver disease is a major cause of morbidity and mortality among Hispanic people living in the United States. Environmental, genetic, and behavioral factors, as well as socioeconomic and health care disparities among this ethnic group have emerged as important public health concerns. We review the epidemiology, natural history, and response to therapy of chronic liver disease in Hispanic patients. The review covers nonalcoholic fatty liver disease, viral hepatitis B and C, coinfection of viral hepatitis with human immunodeficiency virus, alcoholic cirrhosis, hepatocellular carcinoma, autoimmune hepatitis, and primary biliary cirrhosis. For most of these disorders, the Hispanic population has a higher incidence and more aggressive pattern of disease and overall worse treatment outcomes than in the non-Hispanic white population. Clinicians should be aware of these differences in caring for Hispanic patients with chronic liver disease. Copyright © 2011 AGA Institute. Published by Elsevier Inc. All rights reserved.

    Ultrasonography is an important examination for the diagnosis of chronic liver disease. The doctor gives the liver indicators and suggests the patient's condition according to the description of ultrasound report. With the rapid increase in the amount of data of ultrasound report, the workload of professional physician to manually distinguish ultrasound results significantly increases. In this paper, we use the spectral clustering method to cluster analysis of the description of the ultrasound report, and automatically generate the ultrasonic diagnostic diagnosis by machine learning. 110 groups ultrasound examination report of chronic liver disease were selected as test samples in this experiment, and the results were validated by spectral clustering and compared with k-means clustering algorithm. The results show that the accuracy of spectral clustering is 92.73%, which is higher than that of k-means clustering algorithm, which provides a powerful ultrasound-assisted diagnosis for patients with chronic liver disease.

    Hepatitis C virus (HCV) infection is a common chronic liver disease worldwide. Non-alcoholic fatty liver disease and insulin resistance (IR) are the major determinants of fibrosis progression and response to antiviral therapy. The pathogenetic link between IR and chronic HCV infection is complex, and is associated with HCV genotype. Liver steatosis is the most common in the patients infected with genotype 3 virus, possibly due to direct effects of genotype 3 viral proteins. To the contrary, hepatic steatosis in the patients infected with other genotypes is thought to be mostly due to the changes in host metabolism, involving IR. In HCV genotype 3, liver steatosis correlates with viral load, reverts after reaching the sustained virologic response and reoccurs in the relapsers. A therapeutic strategy to improve IR and liver steatosis and subsequently the response to antiviral treatment in these patients is warranted.

    Full Text Available BACKGROUND/OBJECTIVE: Liver biopsy has been the gold standard for grading and staging chronic hepatitis C virus (HCV-mediated liver injury. Traditionally, this has been performed by trained practitioners using a nonimage-guided percutaneous technique at the bedside. Recent literature suggests an expanding role for radiologists in obtaining biopsies using an ultrasound (US-guided technique. The present study was undertaken study to determine if the two techniques produced liver biopsy specimens of similar quality and hypothesized that at our institution, non-US-guided percutaneous liver biopsies for HCV would be of higher quality than US-guided specimens.

    Various studies showed that entecavir (ETV) failed to improve the short-term survival in chronic hepatitis B (CHB) patients with severe acute exacerbation (SAE) and hepatic de-compensation or acute-on-chronic liver failure (ACLF). One study concluded that plasma exchange (PE) significantly decreased the short-term mortality of CHB patients with ACLF who were treated with lamivudine (LAM). Our study was designed to examine the effect of PE on CHB patients with ACLF who were treated with ETV. From August 2010 to January 2015, 38 (PE group) and 120 (control group) consecutive CHB-naïve patients with hepatic de-compensation and ACLF treated with PE plus ETV and ETV, respectively, were recruited. The primary endpoint was liver-related mortality at week 12. Biochemical and virological responses were also studied. At baseline, the PE group had higher serum alanine aminotransferase (ALT) levels and model for end-stage liver disease (MELD) scores, and had lower albumin levels than the control group. The cumulative survival rate at week 4 and week 12 in the PE group and control group were, respectively, 37 and 18 %, and 29 and 14 % (p  0.05). Univariate analysis showed that the control group had a higher liver-related mortality (p = 0.038) at week 12 than the PE group. Multivariate analysis showed that hepatic encephalopathy, ascites, PE treatment, and MELD scores were independent factors for liver-related mortality at week 12. PE significantly improved the short-term survival of CHB patients with hepatic de-compensation and ACLF who were treated with ETV. Hepatic encephalopathy, ascites, PE treatment, and MELD scores were independent factors for liver-related mortality at week 12.

    Chronic liver disease affects 855 people per million in the UK. Previous studies have reported that coffee appears protective against the development of abnormal liver enzymes, hepatic fibrosis and cirrhosis. The aim of this study, the first in a Scottish population, was to compare coffee consumption in patients with liver disease and that of control populations to determine correlations between coffee intake and the incidence of non-cancerous liver disease and with Child's-Pugh and model for end-stage liver disease (MELD) scores. Two hundred and eighty-six patients attending the liver outpatient department at the Royal Infirmary of Edinburgh completed a questionnaire regarding coffee consumption and lifestyle factors. Control questionnaires were also completed by 100 orthopaedic outpatients and 120 medical students. Patients with cirrhosis (n = 95) drank significantly less coffee than those without cirrhosis (p = coffee consumption. Coffee drinking is associated with a reduced prevalence of cirrhosis in patients with chronic liver disease. However, there was no significant difference in the amount of coffee drunk by liver patients and the control groups. It is possible that by changing the amount of coffee drunk, the development of cirrhosis in liver disease could be postponed.

    accessing tertiary hospital liver services are clustered within specific geographic areas. The most striking geographic clustering was seen for people living with chronic hepatitis B, in regions with a relatively high proportion of people born in Vietnam and China. In addition to ethnicity, the data show an apparent ecological association between liver disease and both socioeconomic and educational and/or occupational disadvantage. What are the implications for practitioners? Identifying where demand for clinical services arises is an important step for service planning and preparing for potential outreach programs to optimise community-based care. It is likely that outreach programs to engage and enhance primary care services in geographic areas from which the greatest demand for tertiary liver disease speciality care arises would yield greater relative return on investment than non-targeted outreach programs.

    We examined cranial MRI in 62 patients with CLD. Abnormal finding that high intensity area in symmetrical bilateral basal ganglia other than globus pallidum was found on both T-1 weighted images (T1WI) and fat suppression (chemical shift selective) images. This MRI finding was observed in 32 of 41 patients with cirrhosis while 1 of 21 patients with chronic hepatitis. This MRI finding was irreversible. The incidence of this MRI finding was corelated with severity of CLD and was statistically significant between in the patients with chronic hepatitis and those with cirrhosis. The contributing factors to the incidence of this MRI finding were severity of CLD and total bilirubin level by an analysis with logistic regression model. This MRI finding was detected clearer in a fat suppression imaging than in T1WI. The cause of this MRI finding was supposed not fat related substance by the finding of fat suppression imaging. This MRI finding would be useful for prediction of severity of CLD. (author)

    Acute-on-chronic liver failure (ACLF) is a severe, life-threatening complication, and new and efficient therapeutic strategies for liver failure are urgently needed. Mesenchymal stem cell (MSC) transfusions have been shown to reverse fulminant hepatic failure in mice and to improve liver function in patients with end-stage liver diseases. We assessed the safety and initial efficacy of umbilical cord-derived MSC (UC-MSC) transfusions for ACLF patients associated with hepatitis B virus (HBV) infection. A total of 43 ACLF patients were enrolled for this open-labeled and controlled study; 24 patients were treated with UC-MSCs, and 19 patients were treated with saline as controls. UC-MSC therapy was given three times at 4-week intervals. The liver function, adverse events, and survival rates were evaluated during the 48-week or 72-week follow-up period. No significant side effects were observed during the trial. The UC-MSC transfusions significantly increased the survival rates in ACLF patients; reduced the model for end-stage liver disease scores; increased serum albumin, cholinesterase, and prothrombin activity; and increased platelet counts. Serum total bilirubin and alanine aminotransferase levels were significantly decreased after the UC-MSC transfusions. UC-MSC transfusions are safe in the clinic and may serve as a novel therapeutic approach for HBV-associated ACLF patients. PMID:23197664

    Full Text Available The finding of more severe steatohepatitis in alcohol fed Long Evans (LE compared with Sprague Dawley (SD and Fisher 344 (FS rats prompted us to determine whether host factors related to alcohol metabolism, inflammation, and insulin/IGF signaling predict proneness to alcohol-mediated liver injury. Adult FS, SD, and LE rats were fed liquid diets containing 0% or 37% (calories ethanol for 8 weeks. Among controls, LE rats had significantly higher ALT and reduced GAPDH relative to SD and FS rats. Among ethanol-fed rats, despite similar blood alcohol levels, LE rats had more pronounced steatohepatitis and fibrosis, higher levels of ALT, DNA damage, pro-inflammatory cytokines, ADH, ALDH, catalase, GFAP, desmin, and collagen expression, and reduced insulin receptor binding relative to FS rats. Ethanol-exposed SD rats had intermediate degrees of steatohepatitis, increased ALT, ADH and profibrogenesis gene expression, and suppressed insulin receptor binding and GAPDH expression, while pro-inflammatory cytokines were similarly increased as in LE rats. Ethanol feeding in FS rats only reduced IL-6, ALDH1–3, CYP2E1, and GAPDH expression in liver. In conclusion, susceptibility to chronic steatohepatitis may be driven by factors related to efficiency of ethanol metabolism and degree to which ethanol exposure causes hepatic insulin resistance and cytokine activation.

    Heart to liver ratio on Tl-201 per rectal scintigraphy (shunt index) is known to be useful in the assessment of portal systemic shunt. We assessed Tl-201 uptake pattern and early liver/heart uptake rate of Tl-201 and correlated with shunt index in patients with chronic active hepatitis (CAH) and liver cirrhosis (LC). Fifty eight patients with biopsy-proven chronic liver disease (35 with CAH, 23 with LC) underwent Tl-201 per rectum scintigraphy after instillation of 18.5 MBq of Tl-201 into the upper rectum. We evaluated hepatic uptake (type 1: homogeneous, 2: inhomogeneous segmental, 3: inhomogeneous nonsegmental) and extrahepatic uptake of spleen, heart and kidney (grade 0: no uptake, 1: less than liver, 2: equal to liver, 3: greater than liver). We measured the early liver/heart uptake rate (the slope of the liver to heart uptake ratio for 10 mim) and shunt index (heart to liver uptake ratio). Tl-201 uptake pattern and early liver/heart uptake rate of Tl-201 was correlated with the pathologic diagnosis and shunt index. Hepatic uptake patterns of type 1 and 2 were dominant in CAH (CAH: 27/35, LC: 8/23), and type 3 in LC (CAH: 8/35, LC: 15/23)(p<0.005). The grades of extrahepatic uptake were higher in LC than in CAH (spleen: p<0.001, other soft tissue: p<0.005). The early liver/heart uptake rate of CAH (0.110±0.111) was significantly higher than that of LC (0.014±0.090)(p<0.001). The sensitivity and specificity of the early liver/heart uptake rate were 77.7% and 67.7% in differentiating LC from CAH. There was negative correlation between early liver/heart uptake rate and shunt index (r=-0.3347, p<0.01). Hepatic and extrahepatic uptake pattern and early liver/heart uptake rate on Tl-201 per rectum scintigraphy are useful in the assessment of portal systemic shunt in patients with chronic liver disease

    Advances in the management of children with chronic liver disease have enabled many to survive into adulthood with or without their native livers, so that the most common of these conditions are becoming increasingly common in adult hepatology practice. Because the aetiologies of chronic liver disease in children may vary significantly from those in adulthood, adults with paediatric-onset chronic liver disease may often present with clinical manifestations unfamiliar to their adulthood physician. Transition of medical care to adult practice requires that the adulthood medical staff (primary physicians and subspecialists) have a comprehensive knowledge of childhood liver disease and their implications, and of the differences in caring for these patients. Pending still unavailable Scientific Society guidelines, this article examines causes, presentation modes, evaluation, management, and complications of the main paediatric-onset chronic liver diseases, and discusses key issues to aid in planning a program of transition from paediatric to adult patients.

    The growing epidemic of metabolic syndrome has been related to the increased use of fructose by the food industry. In fact, the use of fructose as an ingredient has increased in sweetened beverages, such as sodas and juices. We thus hypothesized that fructose intake by hypertensive rats would have a worse prognosis in developing metabolic disorder and non-alcoholic fatty liver disease. Male Wistar and SHR rats aged 6weeks were given water or fructose (10%) for 6weeks. Blood glucose was measured every two weeks, and insulin and glucose sensitivity tests were assessed at the end of the follow-up. Systolic blood pressure was measure by plethysmography. Lean mass and abdominal fat mass were collected and weighed. Liver tissue was analyzed to determine interstitial fat deposition and fibrosis. Fasting glucose increased in animals that underwent a high fructose intake, independent of blood pressure levels. Also, insulin resistance was observed in normotensive and mostly in hypertensive rats after fructose intake. Fructose intake caused a 2.5-fold increase in triglycerides levels in both groups. Fructose intake did not change lean mass. However, we found that fructose intake significantly increased abdominal fat mass deposition in normotensive but not in hypertensive rats. Nevertheless, chronic fructose intake only increased fat deposition and fibrosis in the liver in hypertensive rats. We demonstrated that, in normotensive and hypertensive rats, fructose intake increased triglycerides and abdominal fat deposition, and caused insulin resistance. However, hypertensive rats that underwent fructose intake also developed interstitial fat deposition and fibrosis in liver. Copyright © 2016 Elsevier Inc. All rights reserved.

    Recent longitudinal studies have emphasised the prognostic value of noninvasive tests of liver fibrosis and cross-sectional studies have shown their combination significantly improves diagnostic accuracy. To compare the prognostic accuracy of six blood fibrosis tests and liver biopsy, and evaluate if test combination improves the liver-prognosis assessment in chronic hepatitis C (CHC). A total of 373 patients with compensated CHC, liver biopsy (Metavir F) and blood tests targeting fibrosis (APRI, FIB4, Fibrotest, Hepascore, FibroMeter) or cirrhosis (CirrhoMeter) were included. Significant liver-related events (SLRE) and liver-related deaths were recorded during follow-up (started the day of biopsy). During the median follow-up of 9.5 years (3508 person-years), 47 patients had a SLRE and 23 patients died from liver-related causes. For the prediction of first SLRE, most blood tests allowed higher prognostication than Metavir F [Harrell C-index: 0.811 (95% CI: 0.751-0.868)] with a significant increase for FIB4: 0.879 [0.832-0.919] (P = 0.002), FibroMeter: 0.870 [0.812-0.922] (P = 0.005) and APRI: 0.861 [0.813-0.902] (P = 0.039). Multivariate analysis identified FibroMeter, CirrhoMeter and sustained viral response as independent predictors of first SLRE. CirrhoMeter was the only independent predictor of liver-related death. The combination of FibroMeter and CirrhoMeter classifications into a new FM/CM classification improved the liver-prognosis assessment compared to Metavir F staging or single tests by identifying five subgroups of patients with significantly different prognoses. Some blood fibrosis tests are more accurate than liver biopsy for determining liver prognosis in CHC. A new combination of two complementary blood tests, one targeted for fibrosis and the other for cirrhosis, optimises assessment of liver-prognosis. © 2014 John Wiley & Sons Ltd.

    Glutathione-S-transferase P1 (GSTP1) methylation has been demonstrated to be associated with oxidative stress induced liver damage in acute-on-chronic hepatitis B liver failure (ACHBLF). To evaluate the methylation level of GSTP1 promoter in acute-on-chronic hepatitis B liver failure and determine its predictive value for prognosis. One hundred and five patients with acute-on-chronic hepatitis B liver failure, 86 with chronic hepatitis B (CHB) and 30 healthy controls (HC) were retrospectively enrolled. GSTP1 methylation level in peripheral mononuclear cells (PBMC) was detected by MethyLight. Clinical and laboratory parameters were obtained. GSTP1 methylation levels were significantly higher in patients with acute-on-chronic hepatitis B liver failure (median 16.84%, interquartile range 1.83-59.05%) than those with CHB (median 1.25%, interquartile range 0.48-2.47%; P chronic hepatitis B liver failure group, nonsurvivors showed significantly higher GSTP1 methylation levels (P chronic hepatitis B liver failure, GSTP1 methylation showed significantly better predictive value than MELD score [area under the receiver operating characteristic curve (AUC) 0.89 vs. 0.72, P chronic hepatitis B liver failure and shows high predictive value for short-term mortality.

    D-galactose metabolism and demethylation of aminopyrine by healthy controls and patients with chronic active hepatitis (CAH) and cirrhosis (Ci), were assessed by a breath analysis technique measuring /sup 14/CO2 exhalation after oral ingestion of /sup 14/C-D-galactose or /sup 14/C-aminopyrine. Patients with CAH and Ci exhibited decreased /sup 14/CO2-exhalation rates following /sup 14/-D-galactose or /sup 14/C-aminopyrine. D-galactose oxidation capacity of the liver can be assessed by a breath analysis technique in analogy to the demethylating function for aminopyrine. The ordinary oral D-galactose tolerance test seems, however, superior in comparison to the /sup 14/C-D-galactose tolerance test, in discriminating between healthy controls and patients with chronic liver disease.

    Pannexins are transmembrane proteins that form communication channels connecting the cytosol of an individual cell with its extracellular environment. A number of studies have documented the presence of pannexin1 in liver as well as its involvement in inflammatory responses. In this study, it was investigated whether pannexin1 plays a role in acute liver failure and non-alcoholic steatohepatitis, being prototypical acute and chronic liver pathologies, respectively, both featured by liver damage, oxidative stress and inflammation. To this end, wild-type and pannexin1 -/- mice were overdosed with acetaminophen for 1, 6, 24 or 48h or were fed a choline-deficient high-fat diet for 8weeks. Evaluation of the effects of genetic pannexin1 deletion was based on a number of clinically relevant read-outs, including markers of liver damage, histopathological analysis, lipid accumulation, protein adduct formation, oxidative stress and inflammation. In parallel, in order to elucidate molecular pathways affected by pannexin1 deletion as well as to mechanistically anchor the clinical observations, whole transcriptome analysis of liver tissue was performed. The results of this study show that pannexin1 -/- diseased mice present less liver damage and oxidative stress, while inflammation was only decreased in pannexin1 -/- mice in which non-alcoholic steatohepatitis was induced. A multitude of genes related to inflammation, oxidative stress and xenobiotic metabolism were differentially modulated in both liver disease models in wild-type and in pannexin1 -/- mice. Overall, the results of this study suggest that pannexin1 may play a role in the pathogenesis of liver disease. Copyright © 2017 Elsevier B.V. All rights reserved.

    Rising evidence points to endothelial-to-mesenchymal transition (EndMT) as a significant source of the mesenchymal cell population in fibrotic diseases. In this context, we hypothesized that liver endothelial cells undergo EndMT during fibrosis progression. Cirrhosis in mice was induced by CCl 4 A transgenic mouse expressing a red fluorescent protein reporter under the control of Tie2 promoter (Tie2-tdTomato) was used to trace the acquisition of EndMT. Sinusoidal vascular connectivity was evaluated by intravital microscopy and high-resolution three-dimensional confocal microscopy. A modest but significant fraction of liver endothelial cells from both cirrhotic patients and CCl 4 -treated Tie2-tdTomato mice acquired an EndMT phenotype characterized by the coexpression of CD31 and α-smooth muscle actin, compared with noncirrhotic livers. Bone morphogenetic protein-7 (BMP-7) inhibited the acquisition of EndMT induced by transforming growth factor-β1 (TGF-β1) treatment in cultured primary mouse liver endothelial cells from control mice. EndMT was also reduced significantly in vivo in cirrhotic Tie2-tdTomato mice treated intraperitoneally with BMP-7 compared with untreated mice (1.9 ± 0.2 vs. 3.8 ± 0.3%, respectively; P livers correlated with a significant decrease in liver fibrosis ( P livers in both animal models and patients. BMP-7 treatment decreases the occurrence of the EndMT phenotype and has a positive impact on the severity of disease by reducing fibrosis and sinusoidal vascular disorganization. NEW & NOTEWORTHY A subpopulation of liver endothelial cells from cirrhotic patients and mice with liver fibrosis undergoes endothelial-to-mesenchymal transition. Liver endothelial cells from healthy mice could transition into a mesenchymal phenotype in culture in response to TGF-β1 treatment. Fibrotic livers treated chronically with BMP-7 showed lower EndMT acquisition, reduced fibrosis, and improved vascular organization. Copyright © 2017 the American

    2015-01-01

    Full Text Available Cholangiocarcinoma is a malignant tumor, characterized by poor prognosis and a low five-year survival rate. There is a clear correlation between the incidence of opisthorchiasis and high incidence of cholangiocarcinoma in South-East Asia. Liver flukes Clonorchis sinensis and Opisthorchis viverrini are I class carcinogens. There are some endemic regions of opisthorchiasis In the Russian Federation. The most important factor that leads to carcinogenesis during liver fluke infection is chronic inflammation. This review article focuses on the communication of chronic inflammation caused by invasion of liver flukes and cholangiocarcinoma. This paper summarizes the current knowledge about the risk factors for cholangiocarcinoma, as well as knowledge about the molecular aspects of the induction of carcinogenesis by liver flukes.

    To evaluate whether was any difference in the brightness of echogenicity on gray scale ultrasound imaging between the liver with chronic hepatitis and the normal liver using Adobe photoshop 5.0 Seventy-five patients with pathologically proven chronic hepatitis and twenty normal volunteers were included in this study. Adobe photoshop 5.0 histogram was used to measure the brightness of image. The measured brightness of the liver was divided by the brightness of the kidney, and the radio was calculated and compared between patients with chronic hepatitis and the normal control groups. In addition, the degree of fibrosis was also evaluated. The difference in brightness between the normal liver and live with chronic hepatitis was statistically significant, but no statistically significant difference was observed between the brightness of the liver and the degree of fibrosis in the liver. Tissue echo quantification using Adobe Photoshop 5.0 may be a helpful diagnostic methods for the patients with chronic hepatitis.

    1- Anti-liver/kidney microsome autoantibodies type 1 (anti-LKM1), observed in some children with chronic active hepatitis, were used to isolate their antigen in human liver microsomes. A protein, called P-LKM1 was thus purified. This protein was recognized by a rabbit antiserum directed against the related human cytochromes P-450 bufI and P-450 bufII. 2- A human liver microsomal protein immunoprecipitated with anti-LKM1 sera was also recognized by anti cytochromes P-450 bufI/II antibodies. 3- Anti-LKM1 antibodies potently inhibited microsomal bufuralol 1'-hydroxylation. These results displayed the possible identity between cytochrome P-450 bufI/II and LKM1 antigen.

    This review illustrates the state of the art clinical applications and the future perspectives of ultrasound elastographic methods for the evaluation of chronic liver diseases, including the most widely used and validated technique, transient elastography, followed by shear wave elastography and strain imaging elastography. Liver ultrasound elastography allows the non-invasive evaluation of liver stiffness, providing information regarding the stage of fibrosis, comparable to liver biopsy which is still considered the gold standard; in this way, it can help physicians in managing patients, including the decision as to when to start antiviral treatment. The characterization of focal liver lesions and the prognostic role of the elastographic technique in the prediction of complications of cirrhosis are still under investigation.

    Recent advances in the noninvasive imaging of chronic liver disease have led to improvements in diagnosis, particularly with magnetic resonance imaging (MRI). A comprehensive evaluation of the liver may be performed with the quantification of the degree of hepatic steatosis, liver iron concentration, and liver fibrosis. In addition, MRI of the liver may be used to identify complications of cirrhosis, including portal hypertension, ascites, and the development of hepatocellular carcinoma. In this review article, we discuss the state of the art techniques in liver MRI, namely, magnetic resonance elastography, hepatobiliary phase MRI, and liver fat and iron quantification MRI. The use of these advanced techniques in the management of chronic liver diseases, including non-alcoholic fatty liver disease, will be elaborated. PMID:27563019

    Biopsy liver specimens from healthy control subjects (N=5) and patients with various liver diseases (N=43) were investigated by the vitro autoradiography. The Leevy technique of adding /sup 3/H-5-uridine (/sup 3/H-U) to the incubation medium was used. In healthy subjects labeling with /sup 3/H-U was observed mostly in hepatocytes and Kupffer cells and the frequency of /sup 3/H-U labeled cells was extremely high. Higher frequencies of labeled fibrocytes and endothelial cells of the blood vessel were found in acute hepatitis than in control subjects. In the active form of chronic hepatitis, significantly higher counts of labeled fibrocytes, ductular cells and lymphocytes were found. In patients with acute hepatitis or the inactive form of chronic hepatitis, only a few labeled lymphocytes were observed. Larger numbers of labeled fibrocytes were found in patients with chronic hepatitis with sublobular hepatic necrosis, than in patients with the active form of chronic hepatitis. In cirrhotic livers, marked increases of labeled ductular cells, fibrocytes and bile duct cells were found. No significant labeling differences were observed in the hepatocytes of various liver diseases. In chronic hepatitis with sublobular hepatic necrosis, a more significant decrease of labeled Kupffer cells was present than in the inactive form of chronic hepatitis. Labeled ductular cells and fibrocytes increased as the disease progressed from acute hepatitis to liver cirrhosis. The labeling index of rosettes cells was intermediate between the hepatocytes and ductular cells. The ratio of labeled parenchymal to non-parenchymal cells decreased proportionally from chronic hepatitis to cirrhosis.

    The present study was designed to observe the protective effect and mechanisms of meloxicam on liver injury caused by chronic aluminium exposure in rats. The histopathology was detected by hematoxylin-eosin staining. The levels of prostaglandin E2, cyclic adenosine monophosphate and inflammatory cytokines were detected by enzyme linked immunosorbent assay. The expressions of cyclooxygenases-2, prostaglandin E2 receptors and protein kinase A were measured by western blotting and immunohistochemistry. Our experimental results showed that aluminium overload significantly damaged the liver. Aluminium also significantly increased the expressions of cyclooxygenases-2, prostaglandin E2, cyclic adenosine monophosphate, protein kinase A and the prostaglandin E2 receptors (EP1,2,4) and the levels of inflammation and oxidative stress, while significantly decreased the EP3 expression in liver. The administration of meloxicam significantly improved the impairment of liver. The contents of prostaglandin E2 and cyclic adenosine monophosphate were significantly decreased by administration of meloxicam. The administration of meloxicam also significantly decreased the expressions of cyclooxygenases-2 and protein kinase A and the levels of inflammation and oxidative stress, while significantly increased the EP1,2,3,4 expressions in rat liver. Our results suggested that the imbalance of cyclooxygenases-2 and downstream prostaglandin E2 signaling pathway is involved in the injury of chronic aluminium-overload rat liver. The protective mechanism of meloxicam on aluminium-overload liver injury is attributed to reconstruct the balance of cyclooxygenases-2 and downstream prostaglandin E2 signaling pathway.

    When liver disease is severe, the prognosis can be worse if the patient is malnourished. Adequate nutritional support for patients with liver diseases can improve the patient's condition and prognosis. In the case of liver cirrhosis, malnutrition can occur due to a variety of causes, including poor oral intake, maldigestion, malabsorption, associated renal disease, and metabolic abnormalities. For a nutritional assessment, it is important to check the dietary intake, change in body composition, including anthropometry, and a functional assessment of muscle. Counselling and oral or enteral nutrition is preferred over parenteral nutrition as in other diseases. If esophageal varices are present, care should be taken when installing a feeding tube, but if there are ascites, percutaneous endoscopic gastrostomy is contraindicated because of the risk of complications. Calories of 30-35 kcal/kg/day and protein from 1.2 to 1.5 g/kg/day are appropriate. Protein restriction is unnecessary unless the hepatic encephalopathy is severe. A late evening snack and branched chain amino acids can be helpful. In the case of cholestasis, the supply of manganese and copper should be restricted. Sarcopenia in patients with liver cirrhosis is also prevalent and associated with the prognosis.

    Patients with autoimmune chronic active hepatitis (AICAH) and some other chronic liver disorders often have very high titres of rubella HI antibodies. In the present study sera from 46 patients with chronic liver disease and controls were examined for rubella antibodies using radioimmunoprecipitation assay (RIPA) and Western blot. RIPA appeared to be more suitable than Western blot for the study of the individual antibody specificities provided that proteins (possibly actin) interfering with the resolution of the E2 glycoprotein band are identified. It was shown that patients with high rubella HI titres reacted strongly against the E1 glycoprotein and in general also against the core protein (C). Reactivity to the E2 glycoprotein was detected with all sera from patients with chronic liver disease but varied more in strength. Three patients with post-acute rubella showed very faint E2 reactivity, but strong E1 and C reactivities. Patients with primary biliary cirrhosis had normal HI titres and showed no increase in reactivity in RIPA. The present findings show that patients with chronic liver disease and high rubella HI antibody titres exhibit an enhanced specific antibody response to rubella virus structural proteins. (authors)

    Liver steatosis and iron overload, which are frequently observed in chronic hepatitis C (CHC), may contribute to the progression of liver injury. This study aimed to evaluate the correlation between liver steatosis and iron overload in Polish patients with CHC compared to non-alcoholic fatty liver disease (NAFLD) and HFE-hereditary hemochromatosis (HH) patients. A total of 191 CHC patients were compared with 67 NAFLD and 21 HH patients. Liver function tests, serum markers of iron metabolism, cholesterol and triglycerides were assayed. The inflammatory activity, fibrosis, iron deposits and steatosis stages were assessed in liver specimens. HFE gene polymorphisms were investigated by PCR-RFLP. Liver steatosis was associated with obesity and diabetes mellitus. This disease was confirmed in 76/174 (44%) CHC patients, most of whom were infected with genotype 1. The average grade of steatosis was higher in NAFLD patients. CHC patients had significantly higher iron concentrations and transferrin saturations than NAFLD patients. Compared with CHC patients, HH patients had higher values of serum iron parameters and more intensive hepatocyte iron deposits without differences in the prevalence and intensity of liver steatosis. In the CHC group, lipids accumulation in hepatocytes was significantly associated with the presence of serum markers of iron overload. No correlation between the HFE gene polymorphism and liver steatosis in CHC patients was found. Liver steatosis was diagnosed in nearly half of CHC patients, most of whom were infected with genotype 1. The intensity of steatosis was lower in CHC patients than that in NAFLD patients because of a less frequent diagnosis of metabolic syndrome. Only in CHC patients were biochemical markers of iron accumulation positively correlated with liver steatosis; these findings were independent of HFE gene mutations.

    The analysis of multiple causes of death data has been applied in the United States to examine the population burden of chronic liver disease (CLD) and to assess time trends of alcohol-related and hepatitis C virus (HCV)-related CLD mortality. The aim of this study was to assess the mortality for CLD by etiology in the Veneto Region (northeastern Italy). Using the 2008-2010 regional archive of mortality, all causes registered on death certificates were extracted and different descriptive epidemiological measures were computed for HCV-related, alcohol-related, and overall CLD-related mortality. The crude mortality rate of all CLD was close to 40 per 100,000 residents. In middle ages (35 to 74 years) CLD was mentioned in about 10% and 6% of all deaths in males and females, respectively. Etiology was unspecified in about half of CLD deaths. In females and males, respectively, HCV was mentioned in 44% and 21% and alcohol in 11% and 26% of overall CLD deaths. A bimodal distribution with age was observed for HCV-related proportional mortality among females, reflecting the available seroprevalence data. Multiple causes of death analyses can provide useful insights into the burden of CLD mortality according to etiology among different population subgroups.

    To evaluate the efficiency of the treatment with Peginterferon alfa 2a 180 mcg/week, 48 weeks in patients with chronic hepatitis or compensated liver cirrhosis HDV and predictive factors of response to treatment. Prospective study that enrolled 50 patients with chronic hepatitis or compensated cirrhosis HDV between the 1st of January 2011 - 3st of December 2011. The diagnosis of chronic HDV infection was made based on the presence of detectable anti HDV IgG antibodies and HDV-RNA. Patients were evaluated at baseline by CBC, liver function tests, HBV profile, HDV RNA, and by liver biopsy/Fibrotest for evaluating fibrosis and necroinflammatory activity. At 24 weeks CBC (count blood cells), liver function tests, quantitative HBsAg and at 48 and 72 weeks biochemical tests, HDV RNA, HBV DNA, quantitative HBsAg, were performed. Adverse reactions to the treatment were recorded. SVR (sustained virologic response) was recorded in 12 patients (24%) and biochemical response in 28 patients (56%). SVR was correlated with low-grade fibrosis, age, the aminotransferase value and the value of HBsAg at the beginning of the treatment. In week 48 HDV RNA was undetectable in 20 patients (40%). The therapy was well tolerated, except two patients for whom the discontinuation of the treatment was decided for severe exacerbation of cytolysis, respectively hepatic decompensation. In a representative group of patients, the treatment with Peginterferon once again proves its efficacy in treating chronic HDV.

    About 80% of patients with liver cirrhosis may have glucose metabolism disorders, 30% show overt diabetes mellitus (DM). Prospective studies have demonstrated that DM is associated with an increased risk of hepatic complications and death in patients with liver cirrhosis. DM might contribute to liver damage by promoting inflammation and fibrosis through an increase in mitochondrial oxidative stress mediated by adipokines. Based on the above mentioned the effective control of hyperglycemia may have a favorable impact on the evolution of these patients. However, only few therapeutic studies have evaluated the effectiveness and safety of antidiabetic drugs and the impact of the treatment of DM on morbidity and mortality in patients with liver cirrhosis. In addition, oral hypoglycemic agents and insulin may produce hypoglycemia and lactic acidosis, as most of these agents are metabolized by the liver. This review discusses the clinical implications of DM in patients with chronic liver disease. In addition the effectiveness and safety of old, but particularly the new antidiabetic drugs will be described based on pharmacokinetic studies and chronic administration to patients. Recent reports regarding the use of the SGLT2 inhibitors as well as the new incretin-based therapies such as injectable glucagon-like peptide-1 (GLP-1) receptor agonists and oral inhibitors of dipeptidylpeptidase-4 (DPP-4) will be discussed. The establishment of clear guidelines for the management of diabetes in patients with CLD is strongly required.

    Full Text Available Background and Aim. The best staining to evaluate liver fibrosis in liver hepatitis is still a debated topic. This study aimed to compare Masson’s trichrome (MT, Sirius Red (SR, and orcein stainings in evaluating liver fibrosis in chronic HCV hepatitis (CHC with semiquantitative and quantitative methods (Collagen Proportionate Area (CPA by Digital Image Analysis (DIA and correlate them with transient elastography (TE. Methods. Liver stiffness evaluation of 111 consecutive patients with CHC was performed by TE. Semiquantitative staging by Metavir score system and CPA by DIA were assessed on liver biopsy stained with MT, SR, and orcein. Results. MT, SR, and orcein staining showed concordant results in 89.6% of cases in staging CHC, without significant difference in both semiquantitative and quantitative evaluations of fibrosis. TE values were concordant with orcein levels in 86.5% of the cases and with MT/RS in 77.5% (P<0.001. No significant correlation between the grade of necroinflammatory activity and TE values was found. Conclusion. In CHC, SR/MT and orcein stainings are almost concordant and when discordant, orcein staining is better related to TE values than MT/RS. This suggests that elastic fibers play a more important role than reticular or collagenous ones in determining stiffness values in CHC.

    High prevalence of diabetes mellitus in patients with liver cirrhosis has been reported in many studies. The aim of our study was to evaluate the relationship of hepatic fibrosis and steatosis assessed by transient elastography with diabetes in patients with chronic liver disease. The study population consisted of 979 chronic liver disease patients. Liver fibrosis and steatosis were assessed by liver stiffness measurement (LSM) and controlled attenuation parameter (CAP) on transient elastography. Diabetes was diagnosed in 165 (16.9%) of 979 patients. The prevalence of diabetes had significant difference among the etiologies of chronic liver disease. Higher degrees of liver fibrosis and steatosis, assessed by LSM and CAP score, showed higher prevalence of diabetes (F0/1 [14%], F2/3 [18%], F4 [31%], Pdiabetes were hypertension (OR, 1.98; P=0.001), LSM F4 (OR, 1.86; P=0.010), male gender (OR, 1.60; P=0.027), and age>50 yr (OR, 1.52; P=0.046). The degree of hepatic fibrosis but not steatosis assessed by transient elastography has significant relationship with the prevalence of diabetes in patients with chronic liver disease.

    It is essential to accurately predict Postoperative liver failure (PHLF) which is a life-threatening complication. Liver hardness measurement (LSM) is widely used in non-invasive assessment of liver fibrosis. The aims of this study were to explore the application of preoperative liver stiffness measurements (LSM) by transient elastography in predicting postoperative liver failure (PHLF) in patients with hepatitis B related hepatocellular carcinoma. The study included 247 consecutive patients with hepatitis B related hepatocellular carcinoma who underwent hepatectomy between May 2015 and September 2015. Detailed preoperative examinations including LSM were performed before hepatectomy. The endpoint was the development of PHLF. All of the patients had chronic hepatitis B defined as the presence of hepatitis B surface antigen (HBsAg) for more than 6 months and 76 (30.8%) had cirrhosis. PHLF occurred in 37 (14.98%) patients.

    Acoustic Radiation Force Impulse Imaging (ARFI) is a novel non invasive technique studying the localized mechanical properties of tissue by utilising short, high intensity acoustic pulses (shear wave pulses) to assess the mechanical response (tissue displacement), providing a measure of tissue elasticity. The aim of this study is to investigate the feasibility of ARFI imaging as a non-invasive method for the assessment of liver fibrosis compared to liver biopsy scores. A prospective blind comparison study of ARFI elastography (Virtual Touch Imaging., ACUSON S2000 Ultrasound Unit, Siemens, Mountain View CA) in a consecutive series of patients who underwent liver biopsy for assessment of fibrosis in chronic liver disease. ARFI shear-wave propagation velocity was measured in meters per second. Mean ARFI velocities were compared with both Batts-Ludwig (F0 to F4) and Modified Ishak scores (F0 to F4) for fibrosis in liver biopsy findings. Twenty-one patients with chronic liver disease (Hepatitis C (HCV) =16, Hepatitis B (HBV) = 1, both HCV and HBV = 1 Alcoholic liver disease (ALD) = 1, others = 2) underwent ARFI and liver biopsy on the same day. The Spearman correlation coefficients between the median values of the ARFI measurements and the histological fibrosis stage of the Modified Ishak score and Batts-Lud- (3) wig score were both highly significant (p shak score in chronic liver disease. It.s accuracy in prediction of severe fibrosis and cirrhosis is maximal in comparison with earlier stages.

    Full Text Available In this commentary to the paper by Donadon V. et al (Clinical Medicine: Endocrinology and Diabetes. 2009;2:25–33. the association and significance of insulin resistance with chronic liver disease are shortly reviewed and the molecular mechanisms underlying the diabetogenic and oncogenic potentials of advanced liver disease are summarized. Literature studies demonstrate that hepatocellular carcinoma (HCC can be part of the natural history of NASH. HCCs in patients with features of metabolic syndrome as the only risk factor for liver disease have distinct morphological characteristics and mainly occur in the absence of significant fibrosis in the background liver. Moreover, data indicate that the presence of diabetes carries an approximately three to four-fold increased risk of HCC and such a risk is strongly increased by concurrent viral infections. Finally, the relationship between insulin resistance, steatosis and diabetes in NAFLD and HCV infection will be commented, along with the directions for future studies.

    Streptococcus salivarius is an oral commensal bacterium that rarely causes disease in humans. Here, we report a case of liver abscess associated with S. salivarius in a 41-year-old woman who presented with continuous abdominal discomfort, fatigue, and fever. She was diagnosed with multiple liver abscesses; she underwent percutaneous transhepatic abscess drainage. Thereafter, S. salivarius was isolated in all bacterial cultures of the drained abscesses, and it was sensitive to penicillins. She made a good recovery after treatment. In the absence of an infective source other than chronic periodontitis, the cause of liver abscesses was attributed to oral S. salivarius. S. salivarius is a normal oral commensal, and oral commensals must be considered if the infective origin of liver abscess cannot be determined.

    AIM: To evaluate the correlation between liver stiffness measurement (LSM) by real-time shear wave elastography (SWE) and liver fibrosis stage and the accuracy of LSM for predicting significant and advanced fibrosis, in comparison with serum markers. METHODS: We consecutively analyzed 70 patients with various chronic liver diseases. Liver fibrosis was staged from F0 to F4 according to the Batts and Ludwig scoring system. Significant and advanced fibrosis was defined as stage F ≥ 2 and F ≥ 3, respectively. The accuracy of prediction for fibrosis was analyzed using receiver operating characteristic curves. RESULTS: Seventy patients, 15 were belonged to F0-F1 stage, 20 F2, 13 F3 and 22 F4. LSM was increased with progression of fibrosis stage (F0-F1: 6.77 ± 1.72, F2: 9.98 ± 3.99, F3: 15.80 ± 7.73, and F4: 22.09 ± 10.09, P < 0.001). Diagnostic accuracies of LSM for prediction of F ≥ 2 and F ≥ 3 were 0.915 (95%CI: 0.824-0.968, P < 0.001) and 0.913 (95%CI: 0.821-0.967, P < 0.001), respectively. The cut-off values of LSM for prediction of F ≥ 2 and F ≥ 3 were 8.6 kPa with 78.2% sensitivity and 93.3% specificity and 10.46 kPa with 88.6% sensitivity and 80.0% specificity, respectively. However, there were no significant differences between LSM and serum hyaluronic acid and type IV collagen in diagnostic accuracy. CONCLUSION: SWE showed a significant correlation with the severity of liver fibrosis and was useful and accurate to predict significant and advanced fibrosis, comparable with serum markers.

    Single-photon emission computed tomography (SPECT) performed using a rotating gamma camera was compared with ..cap alpha../sub 1/-fetoprotein (AFP) assay, conventional liver scintigraphy, ultrasound (US) imaging, computed tomography (CT), and selective celiac angiography in 40 patients with a total of 50 small hepatocellular carcinomas (HCCs;<5 cm). The detection rates of US and CT were determined on an initial screening study and on a second, more precisely focused study. The detection rate of small HCCs by the various modalities was as follows: AFP, 13%; liver scintigraphy, 36%; SPECT, 72%; initial screening US, 80%; second, more precise US studies, 94%; initial screening CT, 64%; second, more precise CT study, 82%; angiography, 88%. Although SPECT was inferior to the initial screening US examination in detecting HCCs less than 2 cm in size, its sensitivity was identical to that of the initial screening US study for detecting HCCs of 2-5 cm. The combination of SPECT and US was an excellent method for the early detection of HCCs, yielding a detection rate of 94%.

    Highlights: ► The expression of the atypical cadherin FAT1 is increased in chronic liver disease. ► FAT1 expression goes up during the activation of hepatic stellate cells (HSCs). ► Activated HSCs are the cellular source of enhanced FAT1 expression in diseased livers. ► FAT1 enhanced NFkB activity and resistance to apoptosis in activated HSCs. ► FAT1 is a new therapeutic target for prevention and treatment of hepatic fibrosis. -- Abstract: Hepatic fibrosis can be considered as wound healing process in response to hepatocellular injury. Activation of hepatic stellate cells (HSCs) is a key event of hepatic fibrosis since activated HSCs are the cellular source of enhanced extracellular matrix deposition, and reversion of liver fibrosis is accompanied by clearance of activated HSCs by apoptosis. The atypical cadherin FAT1 has been shown to regulate diverse biological functions as cell proliferation and planar cell polarity, and also to affect wound healing. Here, we found increased FAT1 expression in different murine models of chronic liver injury and in cirrhotic livers of patients with different liver disease. Also in hepatic tissue of patients with non-alcoholic steatohepatitis FAT1 expression was significantly enhanced and correlated with collagen alpha I(1) expression. Immunohistochemistry revealed no significant differences in staining intensity between hepatocytes in normal and cirrhotic liver tissue but myofibroblast like cells in fibrotic septa of cirrhotic livers showed a prominent immunosignal. Furthermore, FAT1 mRNA and protein expression markedly increased during in vitro activation of primary human and murine HSCs. Together, these data indicated activated HSCs as cellular source of enhanced FAT1 expression in diseased livers. To gain insight into the functional role of FAT1 in activated HSCs we suppressed FAT1 in these cells by siRNA. We newly found that FAT1 suppression in activated HSCs caused a downregulation of NFκB activity. This

    Acute liver failure can be the consequence of various etiologies, with most cases arising from drug-induced hepatotoxicity in Western countries. Despite advances in this field, the management of acute liver failure continues to be one of the most challenging problems in clinical medicine. The availability of adequate experimental models is of crucial importance to provide a better understanding of this condition and to allow identification of novel drug targets, testing the efficacy of new therapeutic interventions and acting as models for assessing mechanisms of toxicity. Experimental models of hepatotoxicity related to acute liver failure rely on surgical procedures, chemical exposure or viral infection. Each of these models has a number of strengths and weaknesses. This paper specifically reviews commonly used chemical in vivo and in vitro models of hepatotoxicity associated with acute liver failure. - Highlights: • The murine APAP model is very close to what is observed in patients. • The Gal/ET model is useful to study TNFα-mediated apoptotic signaling mechanisms. • Fas receptor activation is an effective model of apoptosis and secondary necrosis. • The ConA model is a relevant model of auto-immune hepatitis and viral hepatitis. • Multiple time point evaluation needed in experimental models of acute liver injury.

    Ammonia is predominantly generated in the gut by intestinal bacteria and enzymes and detoxified primarily in the liver. Since the 1930s, ammonia has been identified as the principal culprit in hepatic encephalopathy (HE). Many physicians utilize serum ammonia to diagnose, assess severity, and determine the resolution of HE in patients with chronic liver disease (CLD) despite research showing that ammonia levels are unhelpful in all of these clinical circumstances. HE in patients with CLD is a clinical diagnosis of exclusion that should not be based on ammonia levels. © 2017 Society of Hospital Medicine.

    Background Pulmonary dysfunctions including the hepatopulmonary syndrome and portosystemic shunt are important complications of hepatic cirrhosis. To investigate the severity and nature of abnormal gas diffusing capacity and its correlation to portosystemic shunt in patients with chronic liver disease. Methods Forty-four patients with chronic liver disease (15 chronic active hepatitis (CAH), 16 Child-Pugh class A, and 13 Child-Pugh class B) without other diseases history were enrolled in the study. Evaluation of liver function tests, arterial blood gases analysis, ultrasonography, pulmonary function test including lung diffusing capacity of carbon monoxide (DLco), forced vital capacity(FVC), forced expiratory volume 1 seconds(FEV1), total lung capacity(TLC), DLco/AV(alveolar volume) and thallium-201 per rectum scintigraphy were performed. We were analyzed correlations between pulmonary function abnormalities and heart/liver (H/L) ratio in patients with chronic liver diseases. Results In CAH, percentage of patients with DLco and DLco/VA (Child-Pugh class A and B patients. The means of DLco and DLco/VA were significantly (P Child-Pugh class. The mean H/L ratio in Child-Pugh class B increased markedly (P Child-Pugh class A. The frequency of specific pulmonary function abnormality in patients with Child-Pugh class B was significantly (P Child-Pugh class A and CAH. There was a inverse linear correlation between H/L ratio and DLco (r = -0.339, P < 0.05) and DLco/VA (r = -0.480, P < 0.01). Conclusion A total of 62% of patients with advanced liver disease have abnormal pulmonary diffusion capacity with a reduced DLco or DLco/VA and abnormal portosystemic shunt (increased H/L ratio) is common hemodynamic abnormality. Therefore, inverse linear correlation between DLco or DLco/VA and H/L ratio may be an important factor in predicting pulmonary complication and meaningful diagnostic and prognostic parameters in patients with advanced chronic liver disease.

    The purpose of this study is to analyze various laboratory indicators of inflammation measured in atomic bomb survivors. Subjects are 6304 survivors who underwent inflammatory tests at RERF between 1998 and 1992 and whose radiation doses (DS86) are available. Inflammatory tests include leukocyte counts, neutrophil counts, erythrocyte sedimentation rate, corrected erythrocyte sedimentation rate, alpha 1 globulin, alpha 2 globulin, and sialic acid. Adjusting for age, sex, smoking, and city of residence, regression analysis was conducted. Regression analysis, adjusted for age, sex, smoking, and city of residence showed statistically significant associations with radiation dose for leukocyte counts (71.0 /mm{sup 3}/Gy, p=0.00151), erythrocyte sedimentation rate (1.58 mm/hour/Gy, p=0.0001), corrected erythrocyte sedimentation rate (1.14 mm/hour/Gy, p=0.0001), alpha 1 globulin (0.0057 g/dl/Gy, p=0.0001), alpha 2 globulin (0.0128 g/dl/Gy, p=0.0001), and sialic acid (1.2711 mg/dl/Gy, p=0.0001), but not for neutrophil counts (29.9 /mm{sup 3}/Gy, p=0.1729). Standardized scores combining results from these seven inflammatory tests showed significant associations with radiation dose both for persons with and without inflammatory disease, and for two inflammatory conditions in particular, chronic thyroiditis and chronic liver disease. In analyses of data from 403 AHS patients, in whom both inflammation indicators and T-cell ratios were measured, increased inflammation correlates with decreases in CD4 T-cells. Since the laboratory indicators of inflammation that we studied are not specific for particular clinical diseases, the implication of their dose-response-pattern is hard to interpret. The general occurrence of infectious diseases in survivors is not related to radiation dose. Such a relationship does exist, however, for other diseases in which infection may play an etiologic role. Virologic studies in A-bomb survivors have suggested dose-response alterations in immune

    Due to their complex and not fully known etiopathogenesis as well as difficulties in treatment, chronic hepatitis and cirrhosis still remain one of the main problems of hepatologists. Nowadays, the use of IFN alpha is considered the most effective method of treatment in chronic hepatitis. Recently, a new property of IFN, i.e. its effects on the reduction of fibrosis, has been discovered. The aim of the paper was to examine the effects of IFN alpha on biochemical parameters (AlAt and AspAt activities), on the metabolic function of the liver and its morphologic picture observed under the light and electron microscope after the 3- and 6-week CCl4-induced damage. The experiments were carried out in Wistar male rats. To evaluate the liver function, the test of aminophenazone elimination in the isolated perfused rat livers was used according to Miller modified by Hafte. Additionally, AspAt and AlAt activities were determined. The liver specimens were analysed under the light and electron microscope and using immunohistochemical methods. The findings show that after the 3-week CCl4-induced liver damage, IFN alpha does not significantly affect AlAt and AspAt activities, irrespective of the dose used. IFN alpha administered after the 6-week damage significantly changes those activities when the doses used are high. It was found that carbon tetrachloride does not result in evident cirrhotic changes, however it activates Ito cells, causes focal retraction of the stroma and fibrosis. The increased number of Ito cells in Disse's space observed in immunohistochemical and ultrastructural examinations is indicative of the activation of liver fibrotic processes following CCl4 administration in both variants used. IFN alpha substantially weakens fibrogenesis of the CCl4-damaged liver which is visible in the decreased number of Ito cells and weaker expression of the stroma retraction. Moreover, IFN alpha administered to the experimental animals after the CCl4-induced injury of the

    Chronic liver disease (CLD) has been suggested to be associated with venous thromboembolism (VTE) in western populations. However, little is known about the risk effects of CLD on VTE among Asians. To compute the prevalence of VTE among hospitalised Asian patients, and to evaluate the pattern and scale of risk effects of CLD on VTE occurrence. Retrospective study of hospital discharge database from 2004 to 2011 to identify patients with VTE and CLD using International Statistical Classification of Diseases and Related Health Problems, 9th Revision, Australian Modification (ICD-9-AM) codes. Of 199904 medically managed inpatients during the 8years, 1744 (0.9%) patients had VTE. Patients with CLD had significant higher prevalence of VTE (non-cirrhosis CLD 1.5%, cirrhosis 2.0%) than patients without CLD (0.8%, pCLD (odds ratio, OR 1.4, 95% CI 1.2-1.7, pCLD, particular liver cirrhosis, increases the risks of VTE in hospitalised Asian patients. As CLD patients are perceived to be at risks of bleeding due to the prolonged clotting times and thrombocytopenia, the results of this study brings attention to opposite end of the haemostatic pendulum in patients with chronic liver disease.

    Acoustic radiation force impulse (ARFI) elastometry quantifies hepatic stiffness, and thus degree of fibrosis, non-invasively. Our aim was to analyse the diagnostic accuracy of ARFI cut-off values, and the significance of a defined limit of standard deviation (SD) as a potential quality parameter for liver fibrosis staging in patients with chronic liver diseases (CLD). 153 patients with CLD (various aetiologies) undergoing liver biopsy, and an additional 25 patients with known liver cirrhosis, were investigated. ARFI measurements were performed in the right hepatic lobe, and correlated with the histopathological Ludwig fibrosis score (inclusion criteria: at least 6 portal tracts). The diagnostic accuracy of cut-off values was analysed with respect to an SD limit of 30% of the mean ARFI value. The mean ARFI elastometry showed 1.95 ± 0.87 m/s (range 0.79-4.40) in 178 patients (80 female, 98 male, mean age: 52 years). The cut-offs were 1.25 m/s for F ≥ 2, 1.72 m/s for F ≥ 3 and 1.75 m/s for F = 4, and the corresponding AUROC 80.7%, 86.2% and 88.7%, respectively. Exclusion of 31 patients (17.4%) with an SD higher than 30% of the mean ARFI improved the diagnostic accuracy: The AUROC for F ≥ 2, F ≥ 3 and F = 4 were 86.1%, 91.2% and 91.5%, respectively. The diagnostic accuracy of ARFI can be improved by applying a maximum SD of 30% of the mean ARFI as a quality parameter--which however leads to an exclusion of a relevant number of patients. ARFI results with a high SD should be interpreted with caution.

Objectives This study aimed to evaluate the association between caffeine consumption and inflammatory activity or degree of liver fibrosis in patients with hepatitis C virus infection. Methods A cross-sectional study of patients with chronic hepatitis C virus infection treated in an outpatient Gastroenterology Unit of Santa Casa Hospital (Porto Alegre - Brasil. Patients were interviewed regarding the consumption of caffeine and anthropometric assessment was performed. Liver biopsy was performed in a maximum period of 36 months before inclusion in the study Results There were 113 patients, 67 (59.3% females, 48 (42.5% were aged between 52 and 62 years, and 101 (89.4% were white. The average caffeine consumption was 251.41 ± 232.32 mg/day, and 70 (62% patients consumed up to 250 mg/day of caffeine. There was no association between caffeine consumption and inflammatory activity on liver biopsy. On the other hand, when evaluating the caffeine consumption liver fibrosis an inverse association was observed. Conclusions The greater consumption of caffeine was associated with lower liver fibrosis. There was no association between caffeine consumption and inflammatory activity.

    Chronic liver (CLD) is a major public health concern. We assessed its effects on quality of life and work productivity, as well as its economic burden in the United States. We performed a cross-sectional study of data from the Medical Expenditure Panel Survey (MEPS; 2004-2013). We extracted participants' sociodemographic parameters and medical histories. Subjects with CLD were identified based on Clinical Classification Software codes. MEPS participants were compared between those with and without CLD, and then between employed and unemployed patients with CLD. Outcomes were quality-of-life scores, employment, and health care use. We collected data from 230,406 adult participants (age, ≥18 y) in the MEPS; 1846 had current CLD (36.7% with viral hepatitis and 5.3% with liver cancer). Individuals with CLD were less likely to be employed (44.7% vs 69.6% patients without CLD), were not working owing to illness/disability (30.5% vs 6.6% without CLD), lost more work because of disability (10.2 vs 3.4 d without CLD), and had more health care use, producing greater health care expenses ($19,390 vs $5567/y without CLD) (all P < .0001). Patients with CLD also had more comorbidities and worse self-reported general and mental health status, and reported more health-related limitations in their daily activities than individuals without CLD (all P < .0001). They also indicated more psychologic distress and depressive symptoms and had a lower quality of life and health utility scores (P < .0001). In multivariate analysis, after adjustment for sociodemographic factors and comorbidities, the presence of CLD was an important predictor of unemployment (odds ratio, 0.60; 95% confidence interval, 0.50-0.70), annual health care expenditure (β = $9503 ± $2028), and impairment in all aspects of health-related quality of life (all P < .0001). In patients with CLD, the presence of liver cancer had the most profound impact on health care expenditures (β = $17,278 ± $5726/y) and

    Full Text Available Obesity and its related metabolic abnormalities, including insulin resistance, alterations in the insulin-like growth factor-1 (IGF-1/IGF-1 receptor (IGF-1R axis, and the state of chronic inflammation, increase the risk of colorectal cancer (CRC and hepatocellular carcinoma (HCC. However, these findings also indicate that the metabolic disorders caused by obesity might be effective targets to prevent the development of CRC and HCC in obese individuals. Green tea catechins (GTCs possess anticancer and chemopreventive properties against cancer in various organs, including the colorectum and liver. GTCs have also been known to exert anti-obesity, antidiabetic, and anti-inflammatory effects, indicating that GTCs might be useful for the prevention of obesity-associated colorectal and liver carcinogenesis. Further, branched-chain amino acids (BCAA, which improve protein malnutrition and prevent progressive hepatic failure in patients with chronic liver diseases, might be also effective for the suppression of obesity-related carcinogenesis because oral supplementation with BCAA reduces the risk of HCC in obese cirrhotic patients. BCAA shows these beneficial effects because they can improve insulin resistance. Here, we review the detailed relationship between metabolic abnormalities and the development of CRC and HCC. We also review evidence, especially that based on our basic and clinical research using GTCs and BCAA, which indicates that targeting metabolic abnormalities by either pharmaceutical or nutritional intervention may be an effective strategy to prevent the development of CRC and HCC in obese individuals.

    The protective effects of juice and fermented vinegar from Hovenia dulcis peduncles on chronically ethanol-induced biochemical changes in male mice were investigated. Administration of ethanol (50%, v/v, 10 mL kg⁻¹) to mice for 6 weeks induced liver damage with a significant increase (P vinegar from Hovenia dulcis peduncles (10 mL kg⁻¹ bw) along with alcohol significantly (P vinegar from Hovenia dulcis peduncles showed better profiles of the antioxidant systems with relatively higher glutathione (GSH) content, total superoxide dismutase (T-SOD), catalase (CAT) and glutathione peroxidase (GSH-Px) activities. All these results were accompanied by histological observations in liver. The results demonstrate that both of the juice and fermented vinegar from Hovenia dulcis peduncles have beneficial effects in reducing the adverse effect of alcohol.

    The relation between liver function and an oral testosterone load was examined in 42 consecutive patients with alcoholic liver cirrhosis. Administration of an oral load of 400 mg micronized free testosterone increased the serum concentration of testosterone (range, 31.9-694.4 nmol/l; median, 140.......8 nmol/l) in male patients with alcoholic liver cirrhosis to significantly (P less than 0.01) higher levels than in male subjects without liver disease (range, 25.4-106.6 nmol/l; median, 61.5 nmol/l). The increase of testosterone after the load (log delta testosterone) in patients correlated inversely...... with wedged-to-free hepatic vein pressure (r = +0.54; P less than 0.01). The increase of testosterone after the load did not correlate significantly with sex hormone-binding globulin (r = +0.35; P greater than 0.05).

    No data are available about the prediction of long-term survival using repeated noninvasive tests of liver fibrosis in chronic hepatitis C (CHC). We aimed to assess the prognostic value of 3-year liver stiffness measurement (LSM), aspartate aminotransferase to platelet ratio index (APRI), and fibrosis 4 (FIB-4) evolution in CHC. CHC patients with two LSM (1,000-1,500 days interval) were prospectively included. Blood fibrosis tests APRI and FIB-4 were calculated the day of baseline (bLSM) and follow-up (fLSM) LSM. Evolution of fibrosis tests was expressed as delta: (follow-up-baseline results)/duration. Date and cause of death were recorded during follow-up that started the day of fLSM. In all, 1,025 patients were included. Median follow-up after fLSM was 38.0 months (interquartile range [IQR]: 27.7-46.1) during which 35 patients died (14 liver-related death) and seven had liver transplantation. Prognostic accuracy (Harrell C-index) of multivariate models including baseline and delta results was not significantly different between LSM and FIB-4 (P ≥ 0.24), whereas FIB-4 provided more accurate prognostic models than APRI (P = 0.03). By multivariate analysis including LSM variables, overall survival was independently predicted by bLSM, delta (dLSM), and sustained virological response (SVR). Prognosis was excellent in patients having bLSM 0 kPa/year) in ≥ 14 kPa bLSM had the worst prognosis. Baseline and delta FIB-4 also identified patient subgroups with significantly different prognosis. Three-year evolution of noninvasive tests of liver fibrosis has a strong prognostic value in CHC patients. These tests should be repeated to monitor patients and predict their outcome. © 2014 by the American Association for the Study of Liver Diseases.

    echo T2 weighted data. Statistical comparison was performed using ANOVA. Results (I) Histopathologic evaluation of both rat and human livers demonstrated no evidence of steatosis or hemochromatosis There was a monotonic increase in mean T2 value with increasing degree of fibrosis (control 65.4±2.9 ms, n=6 patients); mild (Ishak 1–2) 66.7±1.9 ms (n=30); moderate (Ishak 3–4) 71.6±1.7 ms (n=26); severe (Ishak 5–6) 72.4±1.4 ms (n=61); with relatively low standard error (~2.9 ms). There was a statistically significant difference between degrees of mild (Ishak fibrosis (Ishak >4) (P=0.03) based on logistic regression of T2 and Ishak, which became insignificant (P=0.07) when using inflammatory markers as covariates. Expanding on this model using ordinal logistic regression, there was significance amongst all 4 groups comparing T2 to Ishak (P=0.01), with significance using inflammation as a covariate (P=0.03) and approaching statistical significance amongst all groups by ANOVA (P=0.07); (II) there was a monotonic increase in T2 and statistical significance (ANOVA Pliver (e.g., 20–100 ms), demonstrated no statistical difference between two point fits on turbo spin echo (TSE) data and multi-echo CPMG data (P=0.9). Conclusions The finding of increased T2 with liver fibrosis may relate to inflammation that may be an alternative or adjunct to other noninvasive MR imaging based approaches for assessing liver fibrosis.

    Alcohol is frequently used to induce chronic liver injury in laboratory animals. Alcohol causes oxidative stress in the liver and increases the expression of inflammatory mediators that cause hepatocellular damage. However, during chronic liver injury, it is unclear if/how these liver-derived factors affect distal tissues, such as the skin. The purpose of this study was to evaluate skin barrier function during chronic liver injury. Hairless mice were administered 5% or 10% ethanol for 8 weeks, and damages to the liver and skin were assessed using histological and protein-analysis methods, as well as by detecting inflammatory mediators in the plasma. After alcohol administration, the plasma concentration of the aspartate and alanine aminotransferases increased, while albumin levels decreased. In mice with alcohol-induced liver injury, transepidermal water loss was significantly increased, and skin hydration decreased concurrent with ceramide and type I collagen degradation. The plasma concentrations of [Formula: see text]/[Formula: see text] and tumor necrosis factor-alpha (TNF-α) were significantly increased in mice with induced liver injury. TNF receptor (TNFR) 2 expression was upregulated in the skin of alcohol-administered mice, while TNFR1 levels remained constant. Interestingly, the impairment of skin barrier function in mice administered with 10% ethanol was ameliorated by administering an anti-TNF-α antibody. We propose a novel mechanism whereby plasma TNF-α, via TNFR2 alone or with TNFR1, plays an important role in skin barrier function during chronic liver disease in these mouse models.

    To verify the usefulness of FibroQ for predicting fibrosis in patients with chronic hepatitis C, compared with other noninvasive tests. This retrospective cohort study included 237 consecutive patients with chronic hepatitis C who had undergone percutaneous liver biopsy before treatment. FibroQ, aspartate aminotransferase (AST)/alanine aminotransferase ratio (AAR), AST to platelet ratio index, cirrhosis discriminant score, age-platelet index (API), Pohl score, FIB-4 index, and Lok's model were calculated and compared. FibroQ, FIB-4, AAR, API and Lok's model results increased significantly as fibrosis advanced (analysis of variance test: P fibrosis score in chronic hepatitis C compared with other noninvasive tests. FibroQ is a simple and useful test for predicting significant fibrosis in patients with chronic hepatitis C.

    Although chronic liver disease (CLD) constitutes a significant proportion of acute medical admissions, it is not known how CLD influences venous thromboembolism (VTE) prophylaxis decision making and low molecular weight heparin (LMWH) prescription. Furthermore, recent evidence suggests that VTE risk has been underestimated in CLD and that prophylactic LMWH is safe and may improve outcome in this patient group. We therefore evaluated VTE prophylaxis in patients with CLD and aimed to determine the factors contributing to decisions to prescribe LMWH. Prescription of LMWH was significantly less likely in CLD patients than in general medical patients (29% vs 55%; p CLD who were prescribed LMWH were more likely to have been admitted for a 'non-liver' reason than those that did not receive LMWH (19% vs 52%; p CLD, who may benefit from LMWH prophylaxis, do not receive this therapy, because of perceived contraindications for which there may be little evidence. Decision making appears to be affected by whether an admission is 'liver' or 'non-liver' related. Prophylactic LMWH was safe in this small cohort. Further studies are warranted to further inform LMWH prescription in CLD. © 2015 Royal College of Physicians.

    Full Text Available Until recently, a discussion about the mechanisms of development and the biological role of the ductular reaction, which develops in patients with chronic liver diseases continues among hepatologists and pathomorphologists. Purpose of the study. To characterize the pathomorphological features and significance of the ductular response in liver cirrhosis in patients with chronic non-alcoholic, alcoholic and viral hepatitis in hepatobioptats with the use of immunohistochemical (IHC techniques. Material and methods of investigation. Histological, histochemical and IHC study of the ductular liver reaction in liver biopsies of 52 patients aged 24 to 66 years with cirrhosis of the liver on the background of non-alcoholic steatohepatitis (13 patients, and alcoholic steatohepatitis (13 patients and on the background of chronic viral hepatitis C (10 patients, 26–47 years, as well as those suffering from severe biliostasis (8 patients and focal nodular liver hyperplasia (8 patients. Results. The ductular reaction can be detected in the active phase with maximum manifestations in patients with liver cirrhosis on the background of chronic hepatitis, it may have an average or weak degree of severity; in a significant number of patients, the effects of the ductular reaction of the liver are revealed. Cellular chains and groups of cells with the immunophenotype of the progenitor cells of the liver appear in the active phase of the ductular reaction at the periphery of the hepatic lobules in the projection of the Goering canals, in the fibrotically altered portal tracts, in the subcapsular zone of the liver and in the thickened fibrosis septa (c-kit CD117+, CD34+, CD56+ CK7-, CK19-, Hepar- without presence of figures of mitosis or increased level of expression of Кі-67 in them.

    Natural killer T (NKT) cells are CD1d-restricted innate-like T cells that modulate innate and adaptive immune responses. Unlike the well-characterized invariant/type I NKT cells, type II NKT cells with a diverse T cell receptor repertoire are poorly understood. This study defines the pathogenic role of type II NKT cells in the etiology of chronic liver inflammation. Transgenic mice with the Lck promoter directing CD1d overexpression on T cells in Jα18 wild-type (Lck-CD1dTgJα18 + ; type I NKT cell sufficient) and Jα18-deficient (Lck-CD1dTgJα18 o , type I NKT cell deficient) mice were analyzed for liver pathology and crosstalk between type II NKT cells and conventional T cells. CD1d expression on T cells in peripheral blood samples and liver sections from autoimmune hepatitis patients and healthy individuals were also examined. Lck-CD1dTgJα18 o and Lck-CD1dTgJα18 + mice developed similar degrees of liver pathology resembling chronic autoimmune hepatitis in humans. Increased CD1d expression on T cells promoted the activation of type II NKT cells and other T cells. This resulted in T h 1-skewing and impaired T h 2 cytokine production in type II NKT cells. Dysfunction of type II NKT cells was accompanied by conventional T cell activation and pro-inflammatory cytokine production, leading to a hepatic T/B lymphocyte infiltration, elevated autoantibodies and hepatic injury in Lck-CD1dTg mice. A similar mechanism could be extended to humans as CD1d expression is upregulated on activated human T cells and increased presence of CD1d-expressing T cells was observed in autoimmune hepatitis patients. Our data reveals enhanced crosstalk between type II NKT cells and conventional T cells, leading to a T h 1-skewed inflammatory milieu, and consequently, to the development of chronic autoimmune liver disease. Lay summary: CD1d overexpression on T cells enhances crosstalk between type II NKT cells and T cells, resulting in their aberrant activation and leading to the

    Upper gastrointestinal bleeding is one of the most frequent causes of morbidity and mortality in the course of liver cirrhosis. People with liver disease frequently have haemostatic abnormalities such as hyperfibrinolysis. Therefore, antifibrinolytic amino acids have been proposed to be used as supplementary interventions alongside any of the primary treatments for upper gastrointestinal bleeding in people with liver diseases. This is an update of this Cochrane review. To assess the beneficial and harmful effects of antifibrinolytic amino acids for upper gastrointestinal bleeding in people with acute or chronic liver disease. We searched The Cochrane Hepato-Biliary Controlled Trials Register (February 2015), Cochrane Central Register of Controlled Trials (CENTRAL) (Issue 2 of 12, 2015), MEDLINE (Ovid SP) (1946 to February 2015), EMBASE (Ovid SP) (1974 to February 2015), Science Citation Index EXPANDED (1900 to February 2015), LILACS (1982 to February 2015), World Health Organization Clinical Trials Search Portal (accessed 26 February 2015), and the metaRegister of Controlled Trials (accessed 26 February 2015). We scrutinised the reference lists of the retrieved publications. Randomised clinical trials irrespective of blinding, language, or publication status for assessment of benefits and harms. Observational studies for assessment of harms. We planned to summarise data from randomised clinical trials using standard Cochrane methodologies and assessed according to the GRADE approach. We found no randomised clinical trials assessing antifibrinolytic amino acids for treating upper gastrointestinal bleeding in people with acute or chronic liver disease. We did not identify quasi-randomised, historically controlled, or observational studies in which we could assess harms. This updated Cochrane review identified no randomised clinical trials assessing the benefits and harms of antifibrinolytic amino acids for upper gastrointestinal bleeding in people with acute or

    Chronic liver disease questionnaire (CLDQ), a self-administered quality-of-life (QOL) instrument for chronic liver disease (CLD) patients, was originally developed in English language. We aimed to translate and validate CLDQ in Tamil language (CLDQ-T). CLDQ-T, prepared by two forward and two backward independent translations by four bilingual (Tamil and English) persons, and repeated iterative modifications, was validated in adult, native-Tamil patients with CLD. CLDQ-T was re-tested in some patients 2 weeks later. Convergent validity was assessed using Spearman's correlation, and discriminant validity by comparison with World Health Organization's brief QOL tool (WHOQOL-BREF). Reliability was assessed through internal consistency (Cronbach's alpha) and test-retest reliability (intra-class correlation). Cutoff used for statistical significance was p0.700 for individual domains. CLDQ-T was easily understood and showed good performance characteristics in assessing QOL in Tamil-speaking patients with CLD.

    Splenic artery aneurysm (SAA) is a well-known complication of chronic liver disease and portal hypertension in adults. The incidence of SAA in children undergoing selective hepatic angiography prior to liver transplantation is reported as 4%, but there are few systematic studies. To investigate the SAAs detected by multidetector CT angiography (MDCTA) among children with chronic liver disease. A total of 124 children (71 girls, 53 boys; mean age 118 months; age range 5 days to 204 months) with chronic liver disease underwent MDCTA to display the vascular anatomy and any vascular complications during the pretransplantation period. Of these children, 23 also underwent coeliac angiography. The digital subtraction angiography (DSA) and MDCTA findings were compared. SAAs were detected in 13 children (10.4%); none was detectable by US. All patients had more than one aneurysm; ten patients had more than three. In all except one patient, the SAAs were located only in the intraparenchymal branches of the splenic artery; in one patient they were located in the intraparenchymal segment and in the distal third of the splenic artery. The mean size of the aneurysms was 6.5 mm (range 2.5-18 mm). All patients with aneurysms had splenomegaly and vascular collaterals. Nine of the children with SAAs had portal vein pathologies (two occlusions, two stenoses, five dilatations). A statistically significant difference existed with regard to the size of spleen (P < 0.05) and patient age (P < 0.05) between children with SAAs and children without SAAs. There was an increased risk of SAAs in patients with portal vein pathologies. In 19 patients without SAAs on MDCTA, no SAAs were seen on DSA. It is likely that the incidence of SAA in children with chronic liver disease will increase with improved survival of children with long-standing portal hypertension and chronic liver disease. MDCTA with multiplanar reconstruction is a noninvasive and effective means of imaging paediatric patients with

    Full Text Available Lead is harmful for human health and animals. Proanthocyanidins (PCs, a natural antioxidant, possess a broad spectrum of pharmacological and medicinal properties. However, its protective effects against lead-induced liver damage have not been clarified. This study was aimed to evaluate the protective effect of PCs on the hepatotoxicity of male Kunming mice induced by chronic lead exposure. A total of 70 healthy male Kunming mice were averagely divided into four groups: control group, i.e., the group exposed to lead, the group treated with PCs, and the group co-treated with lead and PCs. The mice exposed to lead were given water containing 0.2% lead acetate. Mice treated in the PCs and PCs lead co-treated groups were given PC (100 mg/kg in 0.9% saline by oral gavage. Lead exposure caused a significant elevation in the liver function parameters, lead level, lipid peroxidation, and inhibition of antioxidant enzyme activities. The induction of oxidative stress and histological alterations in the liver were minimized by co-treatment with PCs. Meanwhile, the number of Transferase-Mediated Deoxyuridine Triphosphate-Biotin Nick End Labeling (TUNEL-positive cells was significantly reduced in the PCs/lead co-treated group compared to the lead group. In addition, the lead group showed an increase in the expression level of Bax, while the expression of Bcl-2 was decreased. Furthermore, the lead group showed an increase in the expression level of endoplasmic reticulum (ER stress-related genes and protein (GRP78 and CHOP. Co-treated with PCs significantly reversed these expressions in the liver. PCs were, therefore, demonstrated to have protective, antioxidant, and anti-ER stress and anti-apoptotic activities in liver damage caused by chronic lead exposure in the Kunming mouse. This may be due to the ability of PCs to enhance the ability of liver tissue to protect against oxidative stress via the Nrf2/ARE signaling pathway, resulting in decreasing ER stress

    The aim of this study was to observe the effect of a formulation of traditional Chinese medicine extracts known as Xingnaojia (XNJ) on the liver function, learning ability and memory of rats with chronic alcoholism and to verify the mechanism by which it protects the brain and liver. A rat model of chronic alcoholism was used in the study. The spatial learning ability and memory of the rats were tested. The rats were then sacrificed and their brains and hepatic tissues were isolated. The activity of superoxide dismutase (SOD) and levels of glutamate (Glu), N-methyl D-aspartate receptor subtype 2B (NR2B), cyclin-dependent kinase 5 (CDK5) and cannabinoid receptor 1 (CB1) in the hippocampus were analyzed. The ultrastructure of the hepatic tissue was observed by electron microscopy. In addition, the activities of alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) in serum were tested and the levels of low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglycerides (TG) and total cholesterol (TCHOL) were analyzed. XNJ enhanced the learning and memory of rats with chronic alcoholism. Treatment with XNJ increased the activity of SOD, and decreased the expression levels of NR2B mRNA and NR2B, CB1 and CDK5 proteins in the brain tissues compared with those in the model rats. It also increased the activity of ALDH in the serum and liver, decreased the serum levels of LDL, TG and TCHOL and increased the serum level of HDL. These results indicate that XNJ exhibited a protective effect against brain and liver damage in rats with chronic alcoholism.

    The authors have studied the structure and function of the partially purified insulin receptors from liver and skeletal muscle in a rat model of severe chronic uremia. 125 I-insulin binding was higher in the liver from uremic rats when compared with ad libitum- and pair-fed controls. Furthermore, the ability of insulin to stimulate the autophosphorylation of the β-subunit and insulin receptor kinase activity using Glu 80 , Tyr 20 as exogenous phosphoacceptor was increased in the liver of the uremic animals. The structural characteristics of the receptors, as determined by electrophoretic mobilities of affinity labeled α-subunit and the phosphorylated β-subunit, were normal in uremia. 125 I-insulin binding and insulin receptor kinase activity were similar in the skeletal muscle from uremic and pair- and ad libitum-fed animals. Thus the data are supportive of the hypothesis that in liver and muscle of chronic uremic rats, insulin resistance is due to a defect(s) distal to the insulin receptor kinase

    Full Text Available The phenomenon that the same syndrome turns up in different diseases appears in the sight of people around the world, which raises the thought for possibility of “Same Treatment for Different Diseases.” Actually, treatment based on ZHENG classification in Traditional Chinese Medicine could bring revelation for the former finding. The dampness-heat syndrome in chronic hepatitis B and nonalcoholic fatty liver is regarded as the breakthrough point. We discussed the molecular mechanism of similar connotation that exists in chronic hepatitis B and nonalcoholic fatty liver by metabonomics to give the modern understanding of dampness-heat syndrome. Both urine and serum metabolic profiling revealed that obvious differences existed between dampness-heat syndrome and non-dampness-heat syndrome but the commonality was proved to appear in chronic hepatitis B and nonalcoholic fatty liver patients with dampness-heat syndrome. Furthermore, disorder of body fluid metabolism, decline in digestive capacity, and imbalance of intestinal flora were found to be the new guiding for treatment, with the hope to provide the basis for Chinese personalized medicine.

  20. Liver enzymes serum levels in patients with chronic kidney disease on hemodialysis: a comprehensive review

    2014-04-01

    Full Text Available We reviewed the literature regarding the serum levels of the enzymes aspartate aminotransferase, alanine aminotransferase, and gamma-glutamyl transferase in patients with chronic kidney disease on hemodialysis with and without viral hepatitis. Original articles published up to January 2013 on adult patients with chronic kidney disease on hemodialysis were selected. These articles contained the words “transaminases” “aspartate aminotransferase” “alanine aminotransferase” “gamma glutamyl transferase,” “liver enzymes”, AND “dialysis” OR “hemodialysis”. A total of 823 articles were retrieved. After applying the inclusion and exclusion criteria, 49 articles were selected. The patients with chronic kidney disease on hemodialysis had reduced serum levels of aminotransferases due to hemodilution, lower pyridoxine levels, or elevated homocysteine levels. The chronic kidney disease patients on hemodialysis infected with the hepatitis C virus also had lower aminotransferase levels compared with the infected patients without chronic kidney disease. This reduction is in part due to decreased viremia caused by the dialysis method, the production of a hepatocyte growth factor and endogenous interferon-α, and lymphocyte activation, which decreases viral action on hepatocytes. Few studies were retrieved on gamma-glutamyl transferase serum levels; those found reported that there were no differences between the patients with or without chronic kidney disease. The serum aminotransferase levels were lower in the patients with chronic kidney disease on hemodialysis (with or without viral hepatitis than in the patients with normal renal function; this reduction has a multifactorial origin.

    Patients with chronic liver disease (CLD) have frequent exposure to Clostridium difficile infection (CDI) risk factors but the incidence and aetiology of CDI on this population is poorly understood. The aim of this study was to assess the incidence, disease presentation and outcomes of CDI in patients with underlying CLD. The Health Care and Utilization Project National Inpatient Sample (HCUP-NIS) 2009 dataset was used to identify patients with CLD who developed CDI along with matched non-CLD patients with CDI. Using the NIS dataset, the incidence rate of CDI was 189.4/10 000 discharges in CLD patients vs. 83.7/10 000 discharges in the non-CLD matched cohort (P CLD, comorbidity-matched controls with CDI, CLD patients with CDI had higher likelihood of in-hospital mortality (8.8% vs. 18.6%, P CLD and CDI (n = 41) compared with patients with CDI but not CLD (n = 111), CLD patients had significantly higher Charlson comorbidity index (P CLD patients. In conclusion, CDI-related risk factors were almost universally present in the CLD population. CDI resulted in worse outcomes in this population.

    The present study aims to evaluate iron related parameters in chronic renal failure (CRF) patients on hemodialysis (HD). The study was carried out in Kidney Dialysis Center of Hawler Teaching Hospital in Erbil governorate. This study comprised (76) patients with chronic renal failure on hemodialysis and 41 healthy subjects as a control group of same ages. All hemodialysis patients were taking erythropoietin. The blood samples were taken from the patients before and after the process of hemodialysis for liver parameters and oxidative stress estimations. The results of this study showed lower levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), albumin, total bilirubin, total protein and total antioxidant capacity (TAC), while higher levels of alkaline phosphatase (ALP), direct bilirubin and malondialdeyhde (MDA) before analysis was seen. Hemodialysis causes increasing in AST, ALT, albumin, total bilirubin, total protein and decreasing in ALP, direct bilirubin MDA and TAC.

    It is estimated that globally there is a marked increase in liver disease with reports of rising morbidity and mortality, particularly in younger age groups. Brainstem auditory evoked potential (BAEP) was recorded in 60 decompensated chronic liver disease (DCLD) subjects who fulfilled the selection criteria and compared to 60 age and gender matched healthy subjects with normal liver functions. DCLD subjects were divided into two inter groups based on presence or absence of hepatic encephalopathy (HE). Group 1 comprises of 30 subjects of grade- I HE and Group 2 included 30 subjects without hepatic encephalopathy (NHE). Absolute and interpeak wave latencies were measured. Results were analysed by student independent t- test using SPSS software 11 version. Statistical significance was tested using P value. From the present study it can be concluded that the central nervous system is involved in liver cirrhosis evidenced by an abnormal BAEP latencies parameters. This shows that there may be progressive demyelination occurring along with axonal loss or dysfunction in liver cirrhosis HE. This study suggests that periodic evaluation of cirrhotic individuals to such test will help in monitoring the progress of encephalopathy. The prime goal of this study is early diagnosis and initiation of treatment before the onset of coma can reduce the fatality rate.

    Chronic Liver Disease (CLD) is characterised by gradual destruction of liver tissue over time. Ischemia Modified Albumin (IMA) is an upcoming biomarker shown to be elevated in conditions associated with ischemia and oxidative stress. Albumin levels are greatly reduced in patients with CLD and studying its alterations will provide essential information regarding the molecular changes occurring to it. The study aims to estimate IMA and IMA/Albumin ratio in patients with CLD and to correlate it with parameters assessing liver function and the Model for End Stage Liver Disease (MELD) score. The study consisted of 43 CLD patients as test subjects and 28 apparently healthy individuals as controls. Multiple parameters assessing liver function like albumin, bilirubin, aspartate transaminase (AST), alanine transaminase (ALT), Gamma Glutamyl Transpeptidase (GGT), alkaline phosphatase (ALP), Prothrombin Time (PT) INR and creatinine were estimated and the MELD score calculated. Serum IMA expressed as Absorbance Units (ABSU) was estimated using the Albumin Cobalt Binding test (ABT). Student's t-test and correlation coefficient was used for statistical analysis. Serum IMA was significantly higher in CLD patients (0.5320 ± 0.1677) as compared to the control group (0.3203 ± 0.1257) with a p-value of CLD compared to control group (0.0714 ± 0.0283) with a p-value of CLD could indicate a qualitative change and not merely a quantitative reduction of albumin. IMA can serve as a biomarker to assess the disease severity and prognosis of CLD patients.

    On the basis of studies with hepatorenal syndrome, it is widely regarded that renal function is impacted in chronic liver disease (CLD). Therefore, we investigated renal function in children with CLD. In a retrospective study of 277 children with CLD, renal function was investigated as glomerular filtration rate (GFR) and effective renal plasma flow (ERPF), measured as clearance of inulin and para-amino hippuric acid or clearance of iohexol. The data were analyzed with regard to different subgroups of liver disease and to the grade of damage. Hyperfiltration (>+2 SD of controls) was found in the subgroups of progressive familial intrahepatic cholestasis (44%), glycogenosis (75%), and acute fulminant liver failure (60%). Patients with biliary atresia, most other patients with metabolic disease and intrahepatic cholestasis, and those with vascular anomalies and cryptogenic cirrhosis had normal renal function. Decreased renal function was found in patients with Alagille's syndrome (64% < -2 SD). Increased GFR and ERPF was found in patients with elevated transaminases, low prothrombin level, high bile acid concentration, and high aspartate-aminotransferase-to-platelet ratio. Most children with CLD had surprisingly well preserved renal function and certain groups had even hyperfiltration. The finding that children with decompensated liver disease and ongoing liver failure had stable kidney function suggests that no prognostic markers of threatening hepatorenal syndrome were at hand. Moreover, estimation of GFR based on serum creatinine fails to reveal hyperfiltration.

    Full Text Available Evidence suggests that nonalcoholic fatty liver disease (NAFLD and non-alcoholic steatohepatitis (NASH are associated with an increased risk of chronic kidney disease (CKD. In this study we aimed to evaluate whether the severity of liver fibrosis estimated by NAFLD fibrosis score is associated with higher prevalence of CKD in individuals with NAFLD. To this end NAFLD fibrosis score and estimated glomerular filtration rate (eGFR were assessed in 570 White individuals with ultrasonography-diagnosed NAFLD. As compared with subjects at low probability of liver fibrosis, individuals at high and intermediate probability showed an unfavorable cardio-metabolic risk profile having significantly higher values of waist circumference, insulin resistance, high sensitivity C-reactive protein, fibrinogen, uric acid and lower insulin-like growth factor-1 levels. Individuals at high and intermediate probability of liver fibrosis have lower eGFR after adjustment for gender, smoking, glucose tolerance status, homeostasis model assessment index of insulin resistance (HOMA-IR index, diagnosis of metabolic syndrome, statin therapy, anti-diabetes and anti-hypertensive treatments (P = 0.001. Individuals at high probability of liver fibrosis had a 5.1-fold increased risk of having CKD (OR 5.13, 95%CI 1.13-23.28; P = 0.03 as compared with individuals at low probability after adjustment for age, gender, and BMI. After adjustment for glucose tolerance status, statin therapy, and anti-hypertensive treatment in addition to gender, individuals at high probability of liver fibrosis had a 3.9-fold increased risk of CKD (OR 3.94, 95%CI 1.11-14.05; P = 0.03 as compared with individuals at low probability. In conclusion, advanced liver fibrosis, determined by noninvasive fibrosis markers, is associated with CKD independently from other known factors.

    Full Text Available To investigate the prevalence, mortalities, and patient characteristics of Acute-on-chronic liver failure (ACLF according to the AARC (Asian Pacific Association for the Study of the Liver ACLF Research Consortium and European Association for the Study of the Liver CLIF-C (Chronic Liver Failure Consortium definitions.We collected retrospective data for 1470 hospitalized patients with chronic liver disease (CLD and acute deterioration between January 2013 and December 2013 from 21 university hospitals in Korea.Of the patients assessed, the prevalence of ACLF based on the AARC and CLIF-C definitions was 9.5% and 18.6%, respectively. The 28-day and 90-day mortality rates were higher in patients with ACLF than in those without ACLF. Patients who only met the CLIF-C definition had significantly lower 28-day and 90-day survival rates than those who only met the AARC definition (68.0% vs. 93.9%, P<0.001; 55.1% vs. 92.4%, P<0.001. Among the patients who had non-cirrhotic CLD, the 90-day mortality of the patients with ACLF was higher than of those without ACLF, although not significant (33.3% vs. 6.0%, P = 0.192. Patients with previous acute decompensation (AD within 1- year had a lower 90-day survival rate than those with AD more than 1 year prior or without previous AD (81.0% vs. 91.9% or 89.4%, respectively, all P<0.001. Patients who had extra-hepatic organ failure without liver failure had a similar 90-day survival rate to those who had liver failure as a prerequisite (57.0% vs. 60.6%, P = 0.391.The two ACLF definitions result in differences in mortality and patient characteristics among ACLF patients. We suggest that non-cirrhotic CLD, previous AD within 1 year, and extra-hepatic organ failure should be included in the ACLF diagnostic criteria. In addition, further studies are necessary to develop a universal definition of ACLF.

    Hereditary type 2 diabetes mellitus is a risk factor for chronic liver disease, and ~30 % of patients with liver cirrhosis develop diabetes. Diabetes mellitus has been associated with cirrhotic and non-cirrhotic hepatitis C virus liver infection, can aggravate the course the liver infection, and can induce a lower sustained response to antiviral treatment. Evidences that HCV may induce metabolic and autoimmune disturbances leading to hypobetalipoproteinemia, steatosis, insulin resistance, impaired glucose tolerance, thyroid disease, and gonadal dysfunction have been found. Prospective studies have demonstrated that diabetes increases the risk of liver complications and death in patients with cirrhosis. However, treatment of diabetes in these patients is complex, as antidiabetic drugs can promote hypoglycemia and lactic acidosis. There have been few therapeutic studies evaluating antidiabetic treatments in patients with liver cirrhosis published to date; thus, the optimal treatment for diabetes and the impact of treatment on morbidity and mortality are not clearly known. As numbers of patients with chronic liver disease and diabetes mellitus are increasing, largely because of the global epidemics of obesity and nonalcoholic fatty liver disease, evaluation of treatment options is becoming more important. This review discusses new concepts on hepatogenous diabetes, the diabetes mellitus–hepatitis C virus association, and clinical implications of diabetes mellitus in patients with chronic liver disease. In addition, the effectiveness and safety of old and new antidiabetic drugs, including incretin-based therapies, will be described.

    Red cell Distribution Width (RDW) and platelet ratio (RPR) can predict liver fibrosis and cirrhosis in chronic hepatitis B with relatively high accuracy. RPR was superior to other non-invasive methods to predict liver fibrosis, such as AST and ALT ratio, AST and platelet ratio Index and FIB-4. The aim of this study was to assess diagnostic accuracy liver fibrosis by using RDW and platelets ratio in chronic hepatitis B patients based on compared with Fibroscan. This cross-sectional study was conducted at Adam Malik Hospital from January-June 2015. We examine 34 patients hepatitis B chronic, screen RDW, platelet, and fibroscan. Data were statistically analyzed. The result RPR with ROC procedure has an accuracy of 72.3% (95% CI: 84.1% - 97%). In this study, the RPR had a moderate ability to predict fibrosis degree (p = 0.029 with AUC> 70%). The cutoff value RPR was 0.0591, sensitivity and spesificity were 71.4% and 60%, Positive Prediction Value (PPV) was 55.6% and Negative Predictions Value (NPV) was 75%, positive likelihood ratio was 1.79 and negative likelihood ratio was 0.48. RPR have the ability to predict the degree of liver fibrosis in chronic hepatitis B patients with moderate accuracy.

    CD151, a member of the tetraspanin family of receptors, is a lateral organizer and modulator of activity of several families of transmembrane proteins. It has been implicated in the development and progression of several cancers, but its role in chronic inflammatory disease is less well understood. Here we show that CD151 is upregulated by distinct microenvironmental signals in a range of chronic inflammatory liver diseases and in primary liver cancer, in which it supports lymphocyte recruitment. CD151 was highly expressed in endothelial cells of the hepatic sinusoids and neovessels developing in fibrotic septa and tumor margins. Primary cultures of human hepatic sinusoidal endothelial cells (HSECs) expressed CD151 at the cell membrane and in intracellular vesicles. CD151 was upregulated by VEGF and HepG2 conditioned media but not by proinflammatory cytokines. Confocal microscopy confirmed that CD151 colocalized with the endothelial adhesion molecule/immunoglobulin superfamily member, VCAM-1. Functional flow-based adhesion assays with primary human lymphocytes and HSECs demonstrated a 40% reduction of lymphocyte adhesion with CD151 blockade. Inhibition of lymphocyte adhesion was similar between VCAM-1 blockade and a combination of CD151/VCAM-1 blockade, suggesting a collaborative role between the two receptors. These studies demonstrate that CD151 is upregulated within the liver during chronic inflammation, where it supports lymphocyte recruitment via liver endothelium. We propose that CD151 regulates the activity of VCAM-1 during lymphocyte recruitment to the human liver and could be a novel anti-inflammatory target in chronic liver disease and hepatocellular cancer prevention. NEW & NOTEWORTHY Chronic hepatitis is characterized by lymphocyte accumulation in liver tissue, which drives fibrosis and carcinogenesis. Here, we demonstrate for the first time that the tetraspanin CD151 supports lymphocyte adhesion to liver endothelium. We show that CD151 is upregulated

    Objective: To evaluate the predictive value of a set of laboratory markers for the assessment of liver fibrosis in chronic viral hepatitis patients. Study Design: Cross-sectional study. Place and Duration of Study: Baqai Medical University, Combined Military Hospital, Malir, Karachi, from November 2006 to May 2008. Methodology: Twenty laboratory parameters were measured in 100 treatment-native chronic viral hepatitis patients who also had liver biopsy performed. Descriptive statistics, areas under the ROC's curves, and multivariate logistic regression analysis identified a fibrosis panel, a set of five most useful markers, for the assessment of stages of fibrosis, stage 0 to stage 4. The fibrosis index, FibroScore, consisted of bilirubin, Gamma glutamyl transferase, Hyaluronic acid, alpha 2 macroglobulin, and platelets evaluation. Results: A score of > 0.5 predicted stages 2, 3 and 4, with a sensitivity of 82%, and specificity of 92%. A score > 0.5 for stages 3 and 4 had a sensitivity of 85%, and specificity of 89%. At a score of > 0.80, for stages 3 and 4, the sensitivity was 70%, specificity was 97%, and PPV 87% (there was > 85% possibility of presence of stage 3 or 4). A score of < 0.20 predicted the absence of stages 2, 3, and 4 with a sensitivity of 91%, specificity of 86%, and NPV of 96%. Scores from 0.00 to 0.10 almost certainly ruled out the presence of stages 2-4 (NPV=98%). The areas under the ROC curve were: 0.808 for stage 2; 0.938 for stage 3; and 0.959 for stage 4. Conclusion: A combination of 5 markers is very useful in predicting various stages of liver fibrosis, and is helpful in the non-invasive assessment of liver fibrosis in chronic viral hepatitis patients.

    Alms1 mutant (foz/foz) mice develop hyperphagic obesity, diabetes, metabolic syndrome, and fatty liver (steatosis). High-fat (HF) feeding converts pathology from bland steatosis to nonalcoholic steatohepatitis (NASH) with fibrosis, which leads to cirrhosis in humans. We sought to establish how dietary composition contributes to NASH pathogenesis. foz/foz mice were fed HF diet or chow 24 weeks, or switched HF to chow after 12 weeks. Serum ALT, NAFLD activity score (NAS), fibrosis severity, neutrophil, macrophage and apoptosis immunohistochemistry, uncoupling protein (UCP)2, ATP, NF-κB activation/expression of chemokines/adhesion molecules/fibrogenic pathways were determined. HF intake upregulated liver fatty acid and cholesterol transporter, CD36. Dietary switch expanded adipose tissue and decreased hepatomegaly by lowering triglyceride, cholesterol ester, free cholesterol and diacylglyceride content of liver. There was no change in lipogenesis or fatty acid oxidation pathways; instead, CD36 was suppressed. These diet-induced changes in hepatic lipids improved NAS, reduced neutrophil infiltration, normalized UCP2 and increased ATP; this facilitated apoptosis with a change in macrophage phenotype favoring M2 cells. Dietary switch also abrogated NF-κB activation and chemokine/adhesion molecule expression, and arrested fibrosis by dampening stellate cell activation. Reversion to a physiological dietary composition after HF feeding in foz/foz mice alters body weight distribution but not obesity. This attenuates NASH severity and fibrotic progression by suppressing NF-κB activation and reducing neutrophil and macrophage activation. However, adipose inflammation persists and is associated with continuing apoptosis in the residual fatty liver disease. Taken together, these findings indicate that other measures, such as weight reduction, may be required to fully reverse obesity-related NASH. Copyright © 2013 The Obesity Society.

    AIM: To retrospectively evaluate the prevalence of lymph nodes of the hepato-duodenal ligament in a group of patients with chronic liver disease of various aetiologies and to investigate what clinical, aetiological and laboratory data may lead to their appearance. MATERIALS AND METHODS: One thousand and three patients (554 men, 449 women) were studied, including 557 with chronic hepatitis and 446 with liver cirrhosis. The presence of lymph nodes near the trunk of the portal vein, hepatic artery, celiac axis, superior mesenteric vein and pancreas head was investigated using ultrasound. RESULTS: Lymph nodes were detected in 394 out of the 1003 study patients (39.3%); their number ranged from one to four, with a diameter ranging between 0.8 and 4 cm. The highest prevalence was in the subgroup of patients with primary biliary cirrhosis (87.5%), followed by patients with hepatitis C virus (HCV; 42%), patients with HCV and hepatitis B virus (HBV; 41.3%), autoimmune hepatitis (40%), and HBV alone (21.2%). In the alcoholic and idiopathic subgroups prevalence was 9.5%, while in the non-alcoholic steatohepatitis and haemochromatosis subgroups it was 0%. HCV RNA was present in 97 out of 103 lymph node-positive patients and in 141 out of 168 lymph node-negative HCV-negative patients (p<0.003). Lymphadenopathy frequency increased as the liver disease worsened ({chi}{sup 2} MH=74.3; p<0.0001). CONCLUSION: Despite the limitations of a retrospective study, our data indicate a high prevalence of lymphadenopathy in liver disease patients; ultrasound evidence of lymph nodes of the hepato-duodenal ligament in a given liver disease may most likely suggest a HCV or an autoimmune aetiology and a more severe histological picture.

    Chronic liver disease (CLD) is increasingly recognized as a major public health problem. However, in the United States, there are few nationally representative data on the contribution of viral hepatitis as an etiology of CLD. We applied a previously used International Classification of Diseases, Ninth Revision, Clinical Modification-based definition of CLD cases to the National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey databases for 2006-2010. We estimated the mean number of CLD visits per year, prevalence ratio of visits by patient characteristics, and the percentage of CLD visits attributed to viral hepatitis and other selected etiologies. An estimated 6.0 billion ambulatory care visits occurred in the United States from 2006 to 2010, of which an estimated 25.8 million (0.43%) were CLD-related. Among adults aged 45-64 years, Medicaid and Medicare recipients were 3.9 (prevalence ratio (PR)=3.9, 95% confidence limit (CL; 2.8, 5.4)) and 2.3 (PR=2.3, 95% CL (1.6, 3.4)) times more likely to have a CLD-related ambulatory visit than those with private insurance, respectively. In the United States, from 2006 to 2010, an estimated 49.6% of all CLD-related ambulatory visits were attributed solely to viral hepatitis B and C diagnoses. In this unique application of health-care utilization data, we confirm that viral hepatitis is an important etiology of CLD in the United States, with hepatitis B and C contributing approximately one-half of the CLD burden. CLD ambulatory visits in the United States disproportionately occur among adults, aged 45-64 years, who are primarily minorities, men, and Medicare or Medicaid recipients.

    To establish a practical and reproducible animal model of human acute-on-chronic liver failure for further study of the pathophysiological mechanism of acute-on-chronic liver failure and for drug screening and evaluation in its treatment. Immunological hepatic fibrosis was induced by human serum albumin in Wistar rats. In rats with early-stage cirrhosis (fibrosis stage IV), D-galactosamine and lipopolysaccharide were administered. Mortality and survival time were recorded in 20 rats. Ten rats were sacrificed at 4, 8, and 12 hours. Liver function tests and plasma cytokine levels were measured after D-galactosamine/lipopolysaccharide administration and liver pathology was studied. Cell apoptosis was detected by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling assay. Most of the rats treated with human albumin developed cirrhosis and fibrosis, and 90% of them died from acute liver failure after administration of D-galactosamine/lipopolysaccharide, with a mean survival time of (16.1+/-3.7) hours. Liver histopathology showed massive or submassive necrosis of the regenerated nodules, while fibrosis septa were intact. Liver function tests were compatible with massive necrosis of hepatocytes. Plasma level of TNFalpha increased significantly, parallel with the degree of the hepatocytes apoptosis. Plasma IL-10 levels increased similarly as seen in patients with acute-on-chronic liver failure. We established an animal model of acute-on-chronic liver failure by treating rats with human serum albumin and later with D-galactosamine and lipopolysaccharide. TNFalpha-mediated liver cell apoptoses plays a very important role in the pathogenesis of acute liver failure.

    In patients with chronic liver diseases (CLD), turnover of erythrocytes is increased whereas that of serum albumin is decreased. Thus, glycated hemoglobin (HbA(1C)) and glycated albumin (GA) cannot be used as adequate indicators for chronic plasma glucose control in diabetic patients with CLD. In this investigation, we have proposed CLD-HbA(1C), a novel long-term glycemic control marker by using measured HbA(1C) and GA. We studied 82 patients with CLD in whom glycemic control was regarded as to be stable. Daily plasma glucose profiles were monitored and estimated levels of HbA(1C) were calculated on the conversion formula established by Rohlfing et al. [C.L. Rohlfing, J.D. England, H.M. Wiedmeyer, A. Tennill, R.R. Little, D.E. Goldstein, Defining the relationship between plasma glucose and HbA1c, Diabetes Care 25 (2002) 275-278]. Cholinesterase (ChE) as an indicator for hepatic function was determined at the same time when HbA(1C) and GA levels were measured. CLD-HbA(1C) was defined as the average of measured HbA(1C) and GA/3, based upon the results that among healthy individuals, GA levels were roughly estimated at approximately threefold higher than HbA(1C) levels. While measured HbA(1C) levels in patients with CLD were generally lower than estimated HbA(1C) levels, GA/3 values were generally higher than estimated HbA(1C) levels. Such discrepancies lineally increased in accordance with a decrease in ChE levels. On the other hand, CLD-HbA(1C) levels were highly correlated with estimated HbA(1C) levels (R=0.883), while no significant correlation between CLD-HbA(1C) and ChE was noted. In conclusion, CLD-HbA(1C) has been found a superior chronic glycemic control marker than HbA(1C) or GA in diabetic patients with chronic liver diseases.

    Although a liver stiffness measurement-based model can precisely predict significant intrahepatic inflammation, transient elastography is not commonly available in a primary care center. Additionally, high body mass index and bilirubinemia have notable effects on the accuracy of transient elastography. The present study aimed to create a noninvasive scoring system for the prediction of intrahepatic inflammatory activity related to chronic hepatitis B, without the aid of transient elastography. A total of 396 patients with chronic hepatitis B were enrolled in the present study. Liver biopsies were performed, liver histology was scored using the Scheuer scoring system, and serum markers and liver function were investigated. Inflammatory activity scoring models were constructed for both hepatitis B envelope antigen (+) and hepatitis B envelope antigen (-) patients. The sensitivity, specificity, positive predictive value, negative predictive value, and area under the curve were 86.00%, 84.80%, 62.32%, 95.39%, and 0.9219, respectively, in the hepatitis B envelope antigen (+) group and 91.89%, 89.86%, 70.83%, 97.64%, and 0.9691, respectively, in the hepatitis B envelope antigen (-) group. Significant inflammation related to chronic hepatitis B can be predicted with satisfactory accuracy by using our logistic regression-based scoring system.

Methods: Serum level of PC III was assayed with RIA and other markers of liver function (including ALT, AST, STB, SDB, TP, ALB, TBA) were assayed with automatic biochemical analyzer in 188 patients with various chronic liver diseases. PC III only were examined in 70 controls. Results: (1) The serum levels of PC III were in this order: chronic severe hepatitis (n=27, 501.17 ± 191.09) > liver cirrhosis from chronic hepatitis (n=27,334.52 ± 139.14) > chronic moderate hepatitis ( n = 32,298.02 ± 151.02) > primary liver cancer (n=39,281.42 ± 143.48) > normal controls (n=70,122.56 ± 92.94). (2) The serum levels of PC III were positively correlated with STB and SDB levels (P<0.05) in patients with chronic severe hepatitis and was significantly positively correlated with ALP levels (P<0.01). (3) The serum level of PC III were significantly positively correlated with STB, SDB, TBA and ALP in patients with cirrhosis from chronic hepatitis (P<0.01). (4) The serum levels of PC III were significantly positively correlated with AST and ALP levels in patients with chronic moderate hepatitis (P<0.01). (5) The serum levels of PC III were significantly positively correlated with STB, SDB, TBA, AST and ALP in patients with primary liver cancer (P<0.01). Conclusion: Serum level of PC III might adequately reflect the activity of the process of hepatic fibrosis, but did not necessarily reflect the degree of fibrosis already attained. (authors)

    AIM: To study the effect of WeiJia on chronic liver injury using carbon tetrachloride (CCl4) induced liver injury animal model. METHODS: Wistar rats weighing 180-220g were randomly divided into three groups: normal control group (Group A), CCl4 induced liver injury control group (Group B) and CCl4 induction with WeiJia treatment group (Group C). Each group consisted of 14 rats. Liver damage and fibrosis was induced by subcutaneous injection with 40% CCl4 in olive oil at 3 mL/kg body weight twice a week for eight weeks for Groups B and C rats whereas olive oil was used for Group A rats. Starting from the third week, Group C rats also received daily intraperitoneal injection of WeiJia at a dose of 1.25 μg/kg body weight. Animals were sacrificed at the fifth week (4 male, 3 female), and eighth week (4 male, 3 female) respectively. Degree of fibrosis were measured and serological markers for liver fibrosis and function including hyaluronic acid (HA), type IV collagen (CIV), γ-glutamyl transferase (γ-GT), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were determined. Alpha smooth muscle actin (α-SMA) and proliferating cell nuclear antigen (PCNA) immunohistochemistry were also performed. RESULTS: CCl4 induction led to the damage of liver and development of fibrosis in Group B and Group C rats when compared to Group A rats. The treatment of WeiJia in Group C rats could reduce the fibrosis condition significantly compared to Group B rats. The effect could be observed after three weeks of treatment and was more obvious after eight weeks of treatment. Serum HA, CIV, ALT, AST and γ-GT levels after eight weeks of treatment for Group C rats were 58±22 µg/L (P0.05) respectively, similar to normal control group (Group A), but significantly different from CCl4 induced liver injury control group (Group B). An increase in PCNA and decrease in α-SMA expression level was also observed. CONCLUSION: WeiJia could improve liver function and reduce liver

    The authors conducted a meta-analysis of the prevalence of small intestinal bacterial overgrowth (SIBO) in patients with chronic liver disease (CLD) and controls. Using the search terms "small intestinal bacterial overgrowth (SIBO)" and "chronic liver disease (CLD)" or "cirrhosis," 19 case-control studies were identified. Utilizing breath tests, the prevalence of SIBO in CLD was 35.80% (95% CI, 32.60-39.10) compared with 8.0% (95% CI, 5.70-11.00) in controls. Using culture techniques, the prevalence was 68.31% (95% CI, 59.62-76.00) in CLD patients as compared with 7.94% (95% CI, 3.44-12.73) in controls. No difference between cirrhotic and noncirrhotic patients was found. SIBO is significantly more frequent in CLD patients as compared with controls. The association of SIBO and CLD was not confined to patients with advanced CLD, suggesting that SIBO is not a consequence of advanced liver disease but may play a role in the progression of CLD.

    Chronic consumption of ethanol can cause cumulative liver damage that can ultimately lead to cirrhosis. To explore the mechanisms of alcoholic steatosis, we investigated the global intrahepatic gene expression profiles of livers from mice administered alcohol. Ethanol was administered by feeding the standard Lieber-DeCarli diet, of which 36% (high dose) and 3.6% (low dose) of the total calories were supplied from ethanol for 1, 2, or 4 weeks. Histopathological evaluation of the liver samples revealed fatty changes and punctate necrosis in the high-dose group and ballooning degeneration in the low-dose group. In total, 292 genes were identified as ethanol responsive, and several of these differed significantly in expression compared to those of control mice (two-way ANOVA; p < 0.05). Specifically, the expression levels of genes involved in hepatic lipid transport and metabolism were examined. An overall net increase in gene expression was observed for genes involved in (i) glucose transport and glycolysis, (ii) fatty acid influx and de novo synthesis, (iii) fatty acid esterification to triglycerides, and (iv) cholesterol transport, de novo cholesterol synthesis, and bile acid synthesis. Collectively, these data provide useful information concerning the global gene expression changes that occur due to alcohol intake and provide important insights into the comprehensive mechanisms of chronic alcoholic steatosis

    Liver failure is a clinical syndrome of various etiologies, manifesting as jaundice, encephalopathy, coagulopathy and circulatory dysfunction, which result in subsequent multiorgan failure. Clinically, liver failure is classified into four categories: acute, subacute, acute-on-chronic and chronic liver failure. Massive hepatocyte death is considered to be the core event in the development of liver failure, which occurs when the extent of hepatocyte death is beyond the liver regenerative capacity. Direct damage and immune-mediated liver injury are two major factors involved in this process. Increasing evidence has suggested the essential role of immune-mediated liver injury in the pathogenesis of liver failure. Here, we review the evolved concepts concerning the mechanisms of immune-mediated liver injury in liver failure from human and animal studies. Both innate and adaptive immunity, especially the interaction of various immune cells and molecules as well as death receptor signaling system are discussed. In addition, we highlight the concept of "immune coagulation", which has been shown to be related to the disease progression and liver injury exacerbation in HBV related acute-on-chronic liver failure.

    Photoscintigrams in black and white and in colour were made of the liver and the hepatic clearance was determined by colloidal {sup 198}Au (dimensions 25 - 30 {mu}m) in 82 patients suffering from chronic hepatitis or cirrhosis confirmed by clinical, humeral and histological criteria. The most characteristic changes in the liver scintigram, found particularly in the cirrhosis patients, were: atrophy of the right lobe (partial or total), sometimes pseudo tumoral in appearance; pale or in- homogeneous left lobe; presence of two centres of maximum radiocolloid uptake (left lobe and right lobe); and extrahepatic fixation (spleen, bone marrow). The colour recording system provided better information than the monochromatic system in the diagnosis of cirrhosis. Hepatic clearance showed a decrease, especially in cases of cirrhosis characterized by extrahepatic uptake of the radiocolloid. In the opinion of the authors, the height of the radioactivity curve registered in the temporal region is an indication, during the stabilization phase, of extrahepatic fixation of the colloidal gold. Its height (h{sub 2}) is greater in those cases where the scintigram indicated higher uptake in the spleen and bone marrow. The T 1/2 study of {sup 51}Cr-labelled erythrocytes and their sequestration in the spleen was made in 30 patients exhibiting increased extrahepatic uptake of colloidal gold. The sequestration of labelled erythrocytes was observed in patients showing large-scale splenic uptake of the radiocolloid. Some of the patients whose photoscintigrams previously showed atrophy of the lower region of the right lobe of the liver and obvious presence of the spleen received injections of colloidal gold in the spleen. After intrasplenic injection, the authors obtained the same scintigraphic image in cirrhosis patients, with persistence of the colloidal gold in the spleen, whereas the image of the spleen remained normal in normal subjects. This proves the existence of a lamellar

    The molecular mechanisms of acute hepatitis C virus (HCV) infection, end-stage hepatitis (cirrhosis), and hepatocellular carcinoma have been extensively studied, but little is known of the changes in liver gene expression during the early stages of liver fibrosis associated with chronic HCV infection, that is, the transition from normal liver (NL) of uninfected patients to the first stage of liver fibrosis (F1-CH-C). To obtain insight into the molecular pathogenesis of F1-CH-C, we used real-time quantitative reverse transcriptase-polymerase chain reaction (RT-PCR) to study the mRNA expression of 240 selected genes in liver tissue with F1-CH-C, in comparison with NL. The expression of 54 (22.5%) of the 240 genes was significantly different between F1-CH-C and NL; 46 genes were upregulated and 8 were downregulated in F1-CH-C. The most noteworthy changes in gene expression mainly affected the transcriptional network regulated by interferons (IFNs), including both IFN-α/β-inducible genes (STAT1, STAT2, ISGF3G/IRF9, IFI27, G1P3, G1P2, OAS2, MX1) and IFN-γ-inducible genes (CXCL9, CXCL10, CXCL11). Interesting, upregulation of IFN-α/β-inducible genes (but not IFN-γ-inducible genes) was independent of histological scores (grade and stage of fibrosis) and HCV characteristics (hepatic HCV mRNA levels and the HCV genotype), and was specific to HCV (as compared to hepatitis B virus (HBV)). Other genes dysregulated in F1-CH-C, albeit less markedly than IFN-α/β- and IFN-γ-inducible genes, were mainly involved in the activation of lymphocytes infiltrating the liver (IFNG, TNF, CXCL6, IL6, CCL8, CXCR3, CXCR4, CCR2), cell proliferation (p16/CDKN2A, MKI67, p14/ARF), extracellular matrix remodeling (MMP9, ITGA2), lymphangiogenesis (XLKD1/LYVE), oxidative stress (CYP2E1), and cytoskeleton microtubule organization (STMN2/SCG10). Thus, a limited number of signaling pathways, and particularly the transcriptional network regulated by interferons, are dysregulated in the first

    Upper gastrointestinal bleeding is one of the most frequent causes of morbidity and mortality in the course of liver cirrhosis. Several treatments are used for upper gastrointestinal bleeding in people with liver diseases. One of them is vitamin K administration, but it is not known whether it benefits or harms people with acute or chronic liver disease and upper gastrointestinal bleeding. This is an update of this Cochrane review. To assess the beneficial and harmful effects of vitamin K for people with acute or chronic liver disease and upper gastrointestinal bleeding. We searched The Cochrane Hepato-Biliary Controlled Trials Register (February 2015), the Cochrane Central Register of Controlled Trials (CENTRAL) (Issue 2 of 12, 2015), MEDLINE (Ovid SP) (1946 to February 2015), EMBASE (Ovid SP) (1974 to February 2015), Science Citation Index EXPANDED (1900 to February 2015), and LILACS (1982 to 25 February 2015). We sought additional randomised trials from two registries of clinical trials: the World Health Organization Clinical Trials Search Portal and the metaRegister of Controlled Trials. We looked through the reference lists of the retrieved publications and review articles. Randomised clinical trials irrespective of blinding, language, or publication status for assessment of benefits and harms. We considered observational studies for assessment of harms only. \\We aimed to summarise data from randomised clinical trials using Standard Cochrane methodology and assess them according to the GRADE approach. We found no randomised trials on vitamin K for upper gastrointestinal bleeding in people with liver diseases assessing benefits and harms of the intervention. We identified no quasi-randomised studies, historically controlled studies, or observational studies assessing harms. This updated review found no randomised clinical trials of vitamin K for upper gastrointestinal bleeding in people with liver diseases. The benefits and harms of vitamin K need to be tested

    Hydrocarbon-induced occupational liver injury is a well-known clinical entity among petroleum industry workers. There are many types of hydrocarbon exposure, with inhalation being the most common. Hydrocarbon-induced occupational liver injury is a rarely suspected and commonly missed etiological agent for liver injury. We report a case of a non-petroleum industry worker with chronic liver disease secondary to hydrocarbon-induced occupational liver injury caused by chronic low-grade hydrocarbon ingestion due to occupational malpractice. A 23-year-old Sri Lankan man who was a motor mechanic presented to our hospital with decompensated cirrhosis. He had been chronically exposed to gasoline via inadvertent ingestion due to occupational malpractice. He used to remove gasoline from carburetors by sucking and failed to practice mouth washing thereafter. On evaluation, he had histologically proven established cirrhosis. A comprehensive history and workup ruled out other nonoccupational etiologies for cirrhosis. The patient's long-term occupational gasoline exposure and clinical course led us to a diagnosis of hydrocarbon-induced occupational liver injury leading to decompensated cirrhosis. Hydrocarbon-induced occupational liver injury should be considered as a cause when evaluating a patient with liver injury with possible exposure in relevant occupations.

    Obstructive sleep apnea (OSA) is associated with nonalcoholic fatty liver disease (NAFLD), and causes chronic intermittent hypoxia (CIH) during sleep. Inflammation is associated with the development of metabolic complications induced by CIH. Research suggests that innate immune mechanisms are involved in the pro-inflammatory pathways of liver fibrosis. The purpose of this study was to investigate whether innate immune responses induce liver fibrosis, and to evaluate mechanisms underlying hepatic inflammation related to CIH in a murine diet-induced obesity (DIO) model. Inflammatory and oxidative stress markers, TLR4, MyD88, Toll/interleukin-1-receptor-domain-containing adaptor-inducing interferon-β (TRIF), I-κB, NF-κB, p38 MAPK, c-JNK, and ERK activation, were measured in the serum and liver. As a result, α1(I)-collagen mRNA was significantly higher in DIO mice exposed to CIH than in the control groups. CIH mice exhibited liver fibrosis and significantly higher protein expression of TLR4, MyD88, phosphorylated (phospho-) I-κB, and phospho-ERK1/2 activation in the liver, and higher expression of NF-κB than that in the controls. TRIF, p38 MAPK, and JNK activation did not differ significantly between groups. We conclude that CIH in DIO mice leads to liver fibrosis via TLR4/MyD88/MAPK/NF-kB signaling pathways.

    Full Text Available Objective: To analyse the various abnormal transabdominal ultrasound findings in patients with clinical suspicion of chronic liver disease in our environment with a view of comparing our findings with other existing literatures. Methods: A total of 61 consecutive patients with clinical signs and symptoms of chronic liver disease attending medical outpatient clinic at the Department of Medicine, Usmanu Danfodiyo University, Teaching Hospital Sokoto and Federal Medical Centre Birnin Kebbi were scanned at Radiology Departments for any abnormal intraabdominal findings from May 2011 to April 2012. All the patients were scanned with Apogee 800 plus (Japan 2002 and Concept D (Dynamic Imaging Scotland Ultrasound scanners with a variable frequency probes at 5-12 MHz. Results: A total of 61 abdominal ultrasounds were performed during this study period. All the cases met the inclusion criteria. The mean age was (46.0依12.6 years (ranged 50 years. The mean liver size was (13.25依1.48 cm (ranged 11 cm and (14.00依0.77 cm (ranged 0.77 cm for right and left lobe respectively. The mean spleen size was (15.90依1.22 cm (ranged 6 cm. The sex distribution was males 43 (70.49% and females 18 (29.5%. Of the 61 cases included, the indication for the abdominal ultrasonography were hepatitis 1 (1.6%, liver cirrhosis 20 (50.82%, obstructive jaundice 2 (3.28%, chronic liver disease 25 (40.98% and chronic abdominal swelling 2 (3.2%. Conclusions: In conclusion, our study has demonstrated various abnormal transabdominal ultrasound findings in patients suspected with chronic liver disease in our locality. Ultrasound is useful in the diagnosis of chronic liver disease in daily clinical practice. However, the sensitivity can be improved if a high frequency probe is used and done by experienced and dedicated operators. Liver biopsy remains the gold standard especially when patients are clinically asymptomatic.

    Nonalcoholic fatty liver disease (NAFLD) and diabetes mellitus are common diseases that often coexist and might act synergistically to increase the risk of hepatic and extra-hepatic clinical outcomes. NAFLD affects up to 70-80% of patients with type 2 diabetes mellitus and up to 30-40% of adults with type 1 diabetes mellitus. The coexistence of NAFLD and diabetes mellitus increases the risk of developing not only the more severe forms of NAFLD but also chronic vascular complications of diabetes mellitus. Indeed, substantial evidence links NAFLD with an increased risk of developing cardiovascular disease and other cardiac and arrhythmic complications in patients with type 1 diabetes mellitus or type 2 diabetes mellitus. NAFLD is also associated with an increased risk of developing microvascular diabetic complications, especially chronic kidney disease. This Review focuses on the strong association between NAFLD and the risk of chronic vascular complications in patients with type 1 diabetes mellitus or type 2 diabetes mellitus, thereby promoting an increased awareness of the extra-hepatic implications of this increasingly prevalent and burdensome liver disease. We also discuss the putative underlying mechanisms by which NAFLD contributes to vascular diseases, as well as the emerging role of changes in the gut microbiota (dysbiosis) in the pathogenesis of NAFLD and associated vascular diseases.

    Cu is an essential trace element capable of producing toxic effects in animals and man when ingested acutely or chronically in excess. Although chronic Cu exposure is increasingly recognized as a public health issue, its early effects remain largely unknown. We approached the significance of a moderate chronic Cu load in young rats to correlate early hepatic histopathological changes with functional alterations of liver cells. For this purpose, supplementation with 1,200 ppm of Cu in rat food for 16 weeks was chosen. In these conditions, Cu load elicited a significant decrease in growth curves. There were mild light microscopy alterations in Cu-treated rats, although increasing intracellular Cu storage was correlated with longer Cu exposure both by histological and biochemical measurements. Ultrastructural alterations included lysosomal inclusions as well as mitochondrial and nuclear changes. Liver perfusion studies revealed higher rates of basal O(2) consumption and colloidal carbon-induced O(2) uptake in Cu-treated rats, with enhanced carbon-induced O(2)/carbon uptake ratios and NF-kappaB DNA binding activity. These changes were time-dependent and returned to control values after 12 or 16 weeks. It is concluded that subchronic Cu loading in young rats induces early hepatic morphological changes, with enhancement in Küpffer cell-dependent respiratory burst activity and NF-kappaB DNA binding, cellular responses that may prevent or alleviate the hepatotoxicity of the metal.

    Present study was undertaken to investigate the disturbance in GH. IGF-I and IGFBP-3 axis by evaluating their levels in serum of children with chronic liver disease. twenty-two under normal growth children suffering from cholestasis and chronic viral hepatitis B or C (3-7 years) with mean value (5.05± 1.18 years) compared with twenty healthy children with mean age value (5.07+ 1.37 years) served as control. the malnourished children were classified into 2 groups (l) included 8 cholestatic children and ll: included 14 children with chronic viral hepatitis (HBV or HCV).the biochemical analysis for lover disease as serum alanine aminotransferase (ALT),aspartate aminotransferase (ASTt), alkaline phosphatase (ALP), γ-glutamyl transferase ( γ-GT), total bilirubin, total protein (P), total albumin (A), and prothrombin concentration were performed by colorimetric technique. serum growth hormone (GH), insulin -like growth factor-l (IGF-l) and insulin -like growth factor binding protein- 3 (IGFBP-3) were estimated by radioisotope technique as marker for growth. the biochemical results showed highly significant increases (P< 0.01) in ALT, AST, ALP, γ-GT and total bilirubin respectively in both malnourished groups with chronic liver disease when matched to that of control . total protein , total albumin and prothrombin concentration recorded highly significant decreases (P<0.001) particularly in GR.ll when compared with healthy children . total protein showed non-significant difference in gr.l when compared to control. GH level showed highly significant increases (P<0.01), while IGF-l and IGFBP-3 reported highly significant reduction (P<0.001) in both manourished groups when compared to the normal growth children . the elevation of GH level and reduction of both IGF-l and IGFBP-3 levels were more prominent in children with chronic viral hepatitis than cholestatic children

    A new autoantibody was detected by immunoprecipitation in the serum of 21 patients with chronic active hepatitis. The antibody reacted against a soluble cytosolic antigen in liver. The antibody was organ specific but not species specific and was therefore called anti-liver cytosol antibody Type 1 (anti-LC1). In seven of 21 cases, no other autoantibody was found; the remaining 14 cases had anti-liver/kidney microsome antibody Type 1 (anti-LKM1). With indirect immunofluorescence, a distinctive staining pattern was observed with the seven sera with anti-LC1 and without anti-LKM1. The antibody stained the cytoplasm of hepatocytes from four different animal species and spared the cellular layer around the central veins of mouse and rat liver that we have called juxtavenous hepatocytes. The immunofluorescence pattern disappeared after absorption of sera by a liver cytosol fraction. The 14 sera with both antibodies displayed anti-LC1 immunofluorescent pattern after absorption of anti-LKM1 by the liver microsomal fraction. The anti-LC1 was found in the serum only in patients with chronic active hepatitis of unknown cause. Anti-LC1 antibody was not found in sera from 100 patients with chronic active hepatitis associated with anti-actin antibody classic chronic active hepatitis Type 1, 100 patients with primary biliary cirrhosis, 157 patients with drug-induced hepatitis and a large number of patients with liver and nonliver diseases. This new antibody was considered a second marker of chronic active hepatitis associated with anti-LKM1 (anti-LKM1 chronic active hepatitis) or autoimmune chronic active hepatitis Type 2.

    Liver transplantation represents the first choice treatment for patients with fulminant acute hepatitis and for patients with chronic liver disease and advanced functional failure. Patients in the waiting list for liver transplantation are classified according to the severity of their clinical conditions (evaluated using staging systems mostly based on hematochemical parameters related to liver function). This classification, together with the blood group and the body size compatibility, remains the main criterion for organ allocation. The main indications for liver transplantation are cirrhosis (mainly HCV-, HBV- and alcohol-related) and hepatocellular carcinoma emerging in cirrhosis in adult patients, biliary atresia and some inborn errors of metabolism in pediatric patients. In adults the overall 5-year survival ranges between 60 and 70%, in both American and European series. Even better results have been reported for pediatric patients: in fact, the 5-year survival rate for children ranges between 70 and 80% in the main published series. In this study we evaluated the main medical problems correlated with liver transplantation such as immunosuppressive treatment, acute and chronic rejection, infectious complications, the recurrence of the liver disease leading to transplantation, and cardiovascular and metabolic complications.

    We aimed to elucidate the incidence of protein-energy malnutrition (PEM) in patients with chronic liver disease and to identify factors linked to the presence of PEM.A total of 432 patients with chronic liver disease were analyzed in the current analysis. We defined patients with serum albumin level of ≤3.5 g/dL and nonprotein respiratory quotient (npRQ) value using indirect calorimetry less than 0.85 as those with PEM. We compared between patients with PEM and those without PEM in baseline characteristics and examined factors linked to the presence of PEM using univariate and multivariate analyses.There are 216 patients with chronic hepatitis, 123 with Child-Pugh A, 80 with Child-Pugh B, and 13 with Child-Pugh C. Six patients (2.8%) had PEM in patients with chronic hepatitis, 17 (13.8%) in patients with Child-Pugh A, 42 (52.5%) in patients with Child-Pugh B, and 10 (76.9%) in patients with Child-Pugh C (P < 0.001). Multivariate analysis revealed that Child-Pugh classification (P < 0.001), age ≥64 years (P = 0.0428), aspartate aminotransferase (AST) ≥40 IU/L (P = 0.0023), and branched-chain amino acid to tyrosine ratio (BTR) ≤5.2 (P = 0.0328) were independent predictors linked to the presence of PEM. On the basis of numbers of above risk factors (age, AST, and BTR), the proportions of patients with PEM were well stratified especially in patients with early chronic hepatitis or Child-Pugh A (n = 339, P < 0.0001), while the proportions of patients with PEM tended to be well stratified in patients with Child-Pugh B or C (n = 93, P = 0.0673).Age, AST, and BTR can be useful markers for identifying PEM especially in patients with early stage of chronic liver disease.

    Liver diseases lead to a complex syndrome characterized by neurological, neuro-psychiatric and motor complications, called hepatic encephalopathy, which is prevalent in patients and animal models of acute, sub-chronic and chronic liver failure. Although alterations in GABAergic, glutamatergic, cholinergic and serotonergic neuronal functions have been implicated in HE, the molecular mechanisms that lead to HE in chronic liver disease (CLD) is least illustrated. Due to hepatocellular failure, levels of ammonia and homocysteine (Hcy), in addition to others, are found to increase in the brain as well as plasma. Hcy, a non-protein forming amino acid and an excitotoxin, activates ionotropic glutamate (n-methyl-d-aspartate; NMDA) receptors, and thereby leads to influx of Ca(2+) into neurons, which in turn activates several pathways that trigger oxidative stress, inflammation and apoptosis, collectively called excitotoxicity. Elevated levels of Hcy in the plasma and brain, a condition called Hyperhomocysteinemia (HHcy), and the resultant NMDA receptor-mediated excitotoxicity has been implicated in several diseases, including Parkinson's disease and Alzheimer's disease. Although, hyperammonemia has been shown to cause excitotoxicity, the role of HHcy in the development of behavioral and neurochemical alterations that occur in HE has not been illustrated yet. It is hypothesized that CLD-induced HHcy plays a major role in the development of HE through activation of NMDA receptors. It is further hypothesized that HHcy synergizes with hyperammonemia to activate NMDA receptor in the brain, and thereby cause oxidative stress, inflammation and apoptosis, and neuronal loss that leads to HE.

    Alcoholic liver disease (ALD) is characterized by lipid accumulation and liver injury. However, how chronic alcohol consumption causes hepatic lipid accumulation remains elusive. The present study demonstrates that activation of the mechanistic target of rapamycin complex 1 (mTORC1) plays a causal role in alcoholic steatosis, inflammation, and liver injury. Chronic-plus-binge ethanol feeding led to hyperactivation of mTORC1, as evidenced by increased phosphorylation of mTOR and its downstream kinase S6 kinase 1 (S6K1) in hepatocytes. Aberrant activation of mTORC1 was likely attributed to the defects of the DEP domain-containing mTOR-interacting protein (DEPTOR) and the nicotinamide adenine dinucleotide-dependent deacetylase sirtuin 1 (SIRT1) in the liver of chronic-plus-binge ethanol-fed mice and in the liver of patients with ALD. Conversely, adenoviral overexpression of hepatic DEPTOR suppressed mTORC1 signaling and ameliorated alcoholic hepatosteatosis, inflammation, and acute-on-chronic liver injury. Mechanistically, the lipid-lowering effect of hepatic DEPTOR was attributable to decreased proteolytic processing, nuclear translocation, and transcriptional activity of the lipogenic transcription factor sterol regulatory element-binding protein-1 (SREBP-1). DEPTOR-dependent inhibition of mTORC1 also attenuated alcohol-induced cytoplasmic accumulation of the lipogenic regulator lipin 1 and prevented alcohol-mediated inhibition of fatty acid oxidation. Pharmacological intervention with rapamycin alleviated the ability of alcohol to up-regulate lipogenesis, to down-regulate fatty acid oxidation, and to induce steatogenic phenotypes. Chronic-plus-binge ethanol feeding led to activation of SREBP-1 and lipin 1 through S6K1-dependent and independent mechanisms. Furthermore, hepatocyte-specific deletion of SIRT1 disrupted DEPTOR function, enhanced mTORC1 activity, and exacerbated alcoholic fatty liver, inflammation, and liver injury in mice.

    Full Text Available Our recent studies have revealed the early up-regulated expression of interferon alpha (IFNα in the liver, induced by partial hepatectomy. The role of this cytokine of innate immune response in liver regeneration is still controversial. Aim. To analyze expression of canonical interferon-stimulated genes Ube1l, Ube2l6, Trim25, Usp18 and Isg15 during the liver transition from quiescence to proliferation induced by partial hepatectomy, and acute phase response induced by laparotomy. These genes are responsible for posttranslational modification of proteins by ISGylation. The expression of genes encoding TATA binding protein (TBP and 18S rRNA served as indirect general markers of transcriptional and translational activities. Methods. The abundance of investigated RNAs was assessed in total liver RNA by real time RT–qPCR. Results. Partial hepatecomy induced steady upregulation of the Tbp and 18S rRNA genes expression during 12 hours post-surgery and downregulation or no change in expression of ISGylation-related genes during the first 3 hours followed by slight upregulation at 12 hours. The level of Isg15 transcripts was permanently below that of the control during the prereplicative period. Laparotomy induced a continuous downregulation of Tbp and 18S rRNA expression and early (1–3h upregulation of ISGylation–related transcripts followed by a sharp drop at 6 hours and slight increase/decrease at 12 hours. The changes in the abundance of Ifnα and ISGylation-related mRNAs were oppositely directed at each stage of the response to partial hepatectomy and laparotomy. Conclusion. We suggest that the expression of ISGylation-related genes does not depend on the expression of Ifnα gene after both surgeries. The indirect indices of transcription and translation as well as the expression of ISGylation-relaled genes are principally different in response to partial hepatectomy and laparotomy and argue for the high specificity of innate immune response.

    Pathologists are likely to encounter IgG4-related disease in several organ systems. This article focuses on helping pathologists diagnose IgG4-related disease in the hepatobiliary system. Missing the diagnosis can result in unnecessary organ damage and/or unnecessary surgical and cancer therapy. In the liver, tumefactive lesion(s) involving the bile ducts with storiform fibrosis and an IgG4-enriched lymphoplasmacytic infiltrate are highly concerning for IgG4-related disease. The recent identification of oligoclonal populations of T cells and B cells in IgG4-related disease may lead to molecular tests, new therapeutics, and a greater mechanistic understanding of the disease.

    Full Text Available Chronic Hepatitis B virus (HBV infection can lead to the development of chronic hepatitis, cirrhosis and hepatocellular carcinoma. We hypothesized that HBV might accelerate hepatocyte ageing and investigated the effect of HBV on hepatocyte cell cycle state and biological age. We also investigated the relation between inflammation, fibrosis and cell cycle phase.Liver samples from patients with chronic HBV (n = 91, normal liver (n = 55 and regenerating liver (n = 15 were studied. Immunohistochemistry for cell cycle phase markers and HBV antigens was used to determine host cell cycle phase. Hepatocyte-specific telomere length was evaluated by quantitative fluorescent in-situ hybridization (Q-FISH in conjunction with hepatocyte nuclear area and HBV antigen expression. The effects of induced cell cycle arrest and induced cellular senescence on HBV production were assessed in vitro.13.7% hepatocytes in chronic HBV had entered cell cycle, but expression of markers for S, G2 and M phase was low compared with regenerating liver. Hepatocyte p21 expression was increased (10.9% in chronic HBV and correlated with liver fibrosis. Mean telomere length was reduced in chronic HBV compared to normal. However, within HBV-affected livers, hepatocytes expressing HBV antigens had longer telomeres. Telomere length declined and hepatocyte nuclear size increased as HBV core antigen (HBcAg expression shifted from the nucleus to cytoplasm. Nuclear co-expression of HBcAg and p21 was not observed. Cell cycle arrest induced in vitro was associated with increased HBV production, in contrast to in vitro induction of cellular senescence, which had no effect.Chronic HBV infection was associated with hepatocyte G1 cell cycle arrest and accelerated hepatocyte ageing, implying that HBV induced cellular senescence. However, HBV replication was confined to biologically younger hepatocytes. Changes in the cellular location of HBcAg may be related to the onset of cellular senescence.

    Full Text Available Abstract Background Thiamazole is a widely used antithyroid agent that has been approved for the treatment of hyperthyroidism. Although thiamazole-induced hepatotoxicity is a main side effect, it may progress to liver failure in a very few cases. Case Presentation We described a 24-year-old patient with hyperthyroidism and trilogy of Fallot, who developed liver failure due to thiamazole. Liver biopsy showed intrahepatic cholestasis, mild inflammatory infiltrates, as well as significant fibrosis, indicating both acute and chronic liver injuries. Although a series of potent therapies were given, the patient deceased due to severe liver decompensation. Conclusions This case suggests that thiamazole-induced hepatotoxicity in the setting of advanced fibrosis increases the risk of poor outcome. Regular liver function monitoring during thiamazole therapy is therefore important.

    Hypervascular hyperplastic nodules in those patients with chronic alcoholic liver disease and who are hepatitis B and C negative have recently been reported on. The purpose of this study was to correlate the radiologic and pathologic findings with the clinical significance of these hypervascular hyperplastic nodules in chronic alcoholic liver disease. The study included eight hypervascular nodules of seven patients with chronic alcoholic liver disease, and these patients abused alcohol for more than 20 years. Eight hypervascular nodules were seen on the arterial phase of dynamic CT scans, but the possibility of HCC was excluded pathologically (n=4) or clinically. The radiologic and pathologic findings, and the changes of these nodules on follow up CT scans were retrospectively analyzed. All nodules showed good enhancement on the arterial phase. The tissue equilibrium phase of the dynamic CT scans showed isodensity in seven patients and low density in one patient. Ultrasound scans revealed hypoechoic findings for three nodules, isoechoic findings for two nodules, hyperechoic findings for one nodules, and two nodules were not detected. Angiograms (n=6) showed late incremental tumor staining, and all the nodules were well seen on the sinusoidal phase. CT during hepatic angiography (n=4) showed well stained tumor. CT during arterial portography (n=4) showed no defect in three nodules and nodular defect in on nodule. The MR images (n=3) showed low signal intensity in two nodules and iso-signal intensity in one nodule on T2WI. Five of six cases for which follow up CT scans were performed showed decrease in size and one was disappeared. Radiologically, it is often difficult to differentiate the hypervascular hyperplastic nodules seen in the chronic alcoholic liver disease from hepatocellular carcinoma, and histological confirmation is needed for excluded hepatocellular carcinoma.

    Immunohistochemical detection of cold shock proteins is predictive for deleterious outcome in various malignant diseases. We recently described active secretion of a family member, denoted Y-box (YB) protein-1. We tested the clinical and diagnostic value of YB-1 protein fragment p18 (YB-1/p18) detection in blood for malignant diseases. We used a novel monoclonal anti-YB-1 antibody to detect YB-1/p18 by immunoblotting in plasma samples of healthy volunteers (n = 33), patients with non-cancerous, mostly inflammatory diseases (n = 60), hepatocellular carcinoma (HCC; n = 25) and advanced solid tumors (n = 20). YB-1/p18 was then tested in 111 patients with chronic liver diseases, alongside established tumor markers and various diagnostic measures, during evaluation for potential liver transplantation. We developed a novel immunoblot to detect the 18 kD fragment of secreted YB-1 in human plasma (YB-1/p18) that contains the cold-shock domains (CSD) 1-3 of the full-length protein. YB-1/p18 was detected in 11/25 HCC and 16/20 advanced carcinomas compared to 0/33 healthy volunteers and 10/60 patients with non-cancerous diseases. In 111 patients with chronic liver disease, YB-1/p18 was detected in 20 samples. Its occurrence was not associated with advanced Child stages of liver cirrhosis or liver function. In this cohort, YB-1/p18 was not a good marker for HCC, but proved most powerful in detecting malignancies other than HCC (60% positive) with a lower rate of false-positive results compared to established tumor markers. Alpha-fetoprotein (AFP) was most sensitive in detecting HCC, but simultaneous assessment of AFP, CA19-9 and YB-1/p18 improved overall identification of HCC patients. Plasma YB-1/p18 can identify patients with malignancies, independent of acute inflammation, renal impairment or liver dysfunction. The detection of YB-1/p18 in human plasma may have potential as a tumor marker for screening of high-risk populations, e.g. before organ transplantation, and should

    Full Text Available Recent reports suggest a role for the Patatin-like phospholipase domain-containing protein 3 (PNPLA3 in the pathology of non-alcoholic fatty liver disease (NAFLD. Lipid deposition in the liver seems to be a critical process in the pathogenesis of NAFLD. The aim of the present work was to evaluate the association between the liver PNPLA3 expression, key genes of lipid metabolism, and the presence of NAFLD in morbidly obese women. We used real-time polymerase chain reaction (PCR analysis to analyze the hepatic expression of PNPLA3 and lipid metabolism-related genes in 55 morbidly obese subjects with normal liver histology (NL, n = 18, simple steatosis (SS, n = 20, and non-alcoholic steatohepatitis (NASH, n = 17. Liver biopsies were collected during bariatric surgery. We observed that liver PNPLA3 expression was increased in NAFLD than in NL. It was also upregulated in SS than in NL. Interestingly, we found that the expression of PNPLA3 was significantly higher in severe than mild SS group. In addition, the expression of the transcription factors LXRα, PPARα, and SREBP2 was positively correlated with PNPLA3 liver expression. Regarding rs738409 polymorphism, GG genotype was positive correlated with the presence of NASH. In conclusion, our results show that PNPLA3 could be related to lipid accumulation in liver, mainly in the development and progression of simple steatosis.

    This study aimed to elucidate predictors of liver fibrosis in patients with chronic hepatitis B virus (HBV) infection. Transient elastography was performed to define liver stiffness in 533 patients with chronic HBV infection (mean age ± standard deviation, 30.72 ± 0.57 years). Protein array was performed on serum samples and lysates of Huh7 cells transfected with HBV mutants; the results were confirmed by enzyme-linked immunosorbent assay. Single-nucleotide polymorphisms in the gene encoding interleukin 1β (IL-1β) were examined in patients with chronic HBV infection with and without liver fibrosis. Male sex, age ≥18 years, and serum α-fetoprotein level >3.6 ng/mL were independent predictors of a liver stiffness measurement of ≥7 kPa (P = .005, .019, and rs16944 and the CC genotype at rs1143627 in the gene encoding IL-1β were associated with higher serum IL-1β levels and liver fibrosis. Male sex, age ≥18 years, elevated α-fetoprotein level, and HBeAg-negative hepatitis are risk factors for liver fibrosis. IL-1β is involved in the progression of liver fibrosis in subjects with HBeAg-negative hepatitis.

    Full Text Available Chronic alcoholics who also binge drink (i.e., acute on chronic are prone to an exacerbated liver injury but its mechanism is not understood. We therefore investigated the in vivo effects of chronic and binge ethanol ingestion and compared to chronic ethanol followed by three repeat binge ethanol on the liver of male C57/BL6 mice fed ethanol in liquid diet (4% for four weeks followed by binge ethanol (intragastric administration, 3.5 g/kg body weight, three doses, 12h apart. Chronic followed by binge ethanol exacerbated fat accumulation, necrosis, decrease in hepatic SAM and SAM:SAH ratio, increase in adenosine levels, and elevated CYP2E1 levels. Histone H3 lysine acetylation (H3AcK9, dually modified phosphoacetylated histone H3 (H3AcK9/PS10, and phosphorylated H2AX increased after binge whereas phosphorylation of histone H3 ser 10 (H3S10 and H3 ser 28 (H3S28 increased after chronic ethanol-binge. Histone H3 lysine 4 and 9 dimethylation increased with a marked dimethylation in H3K9 in chronic ethanol binge group. Trimethylated histone H3 levels did not change. Nuclear levels of histone acetyl transferase GCN5 and histone deacetylase HDAC3 were elevated whereas phospho-CREB decreased in a distinctive manner. Taken together, acute on chronic ethanol ingestion caused amplification of liver injury and elicited characteristic profiles of histone modifications, metabolic alterations, and changes in nuclear protein levels. These findings demonstrate that chronic ethanol exposure renders liver more susceptible to repeat acute/binge ethanol induced acceleration of alcoholic liver disease.

    Carvedilol is an anti-oxidant non-selective β-blocker used for reduction of portal blood pressure, prophylaxis of esophageal varices development and bleeding in chronic liver diseases. Recently, it exhibited potent anti-inflammatory, anti-fibrotic, anti-proliferative and anti-carcinogenic effects. In the present study, we evaluated the possible suppressive effect of carvedilol on circulating and hepatic IL-6 levels responsible for hepatocarcinogenesis in a rat model of hepatic cirrhosis. Besides, its effect on hepatic STAT-3 levels, function tests, oxidative stress markers, and hydroxyproline content, hepatic tissue histopathological changes and immunohistochemical expression of E & N-cadherin. Nine-week-old male Wistar rats injected intraperitoneal by 1 ml/kg 10% CCL 4 in olive oil three times/week (every other day) for 12 weeks to induce hepatic cirrhosis. Carvedilol (10 mg/kg/day suspended in 0.5% CMC orally), silymarin (50 mg/kg/day suspended in 0.5% CMC orally) or combination of both used to treat hepatic cirrhosis from 15th to 84th day. Our data showed that carvedilol and silymarin co-treatment each alone or in combination efficiently reduced the elevated serum IL-6, ALT, AST, ALP and BIL, hepatic IL-6, STAT-3, MDA levels and hydroxyproline content. In addition, it elevated the reduced serum ALB level, hepatic CAT activity and GSH level. Meanwhile, it apparently restored the normal hepatic architecture, collagen distribution and immunohistochemical E & N-cadherin expression. Furthermore, carvedilol was superior to silymarin in improving MDA level. Moreover, the combination of carvedilol and silymarin showed an upper hand in amelioration of the CCL 4 induced hepatotoxicity than each alone. Therefore, carvedilol could be promising in prevention of hepatocarcinogenesis in chronic hepatic injuries. - Highlights: • Chronic liver damage ends into hepatocellular carcinoma in 5% of patients. • Persistent elevation of IL-6 induces hepatocarcinogenesis in chronic

    Bleeding is a serious and frequent complication of peptic ulcer disease. Hepatic dysfunction can cause coagulopathy and increases the risk of peptic ulcer bleeding. However, whether chronic liver disease increases mortality after peptic ulcer bleeding remains unclear. To examine the prognostic impact of chronic liver disease on mortality after peptic ulcer bleeding. We used population-based medical registries to conduct a cohort study of all Danish residents hospitalised with incident peptic ulcer bleeding from 2004 through 2011. We identified patients diagnosed with liver cirrhosis or non-cirrhotic chronic liver disease before their admission for peptic ulcer bleeding. We then computed 90-day mortality after peptic ulcer bleeding based on the Kaplan-Meier method (1 - survival function) and used a Cox regression model to estimate mortality rate ratios (MRRs), controlling for potential confounders. We identified 21,359 patients hospitalised with peptic ulcer bleeding. Among these, 653 (3.1%) had a previous diagnosis of liver cirrhosis and 474 (2.2%) had a history of non-cirrhotic chronic liver disease. Patients with liver cirrhosis and non-cirrhotic chronic liver disease had a cumulative 90-day mortality of 25.3% and 20.7%, respectively, compared to 18.3% among patients without chronic liver disease. Liver cirrhosis was associated with an adjusted 90-day MRR of 2.38 (95% CI: 2.02-2.80), compared to 1.49 (95% CI: 1.22-1.83) among patients with non-cirrhotic chronic liver disease. Patients with chronic liver disease, particularly liver cirrhosis, are at increased risk of death within 90 days after hospitalisation for peptic ulcer bleeding compared to patients without chronic liver disease. © 2015 John Wiley & Sons Ltd.

    Background: The accurate evaluation of liver fibrosis stage is important in determining the treatment strategy. The limitations of percutaneous liver biopsy as the gold standard are obvious for invasion. Real-time elastography with conventional ultrasound probes and a new quantitative technology for diffuse histological lesion is a novel approach for staging of liver fibrosis. Purpose: This study aimed to evaluate the value of real-time tissue elastography with a new quantitative technology for the assessment of liver fibrosis stage. Materials and methods: Real-time elastography was performed in 55 patients with liver fibrosis and chronic hepatitis B and in 20 healthy volunteers. Eleven parameters for every patient in colorcode image obtained from the real-time elastography were analyzed with principal components analysis. We analyzed the correlation between elasticity index and liver fibrosis stage and the accuracy of real-time elastography for liver fibrosis staging. Additionally, aspartate transaminase-to-platelet ratio index was also included in the analysis. Results: The Spearman's correlation coefficient between the elasticity index and the histologic fibrosis stage was 0.81, which is highly significant (p 0.05), respectively. Conclusions: Real-time elastography with a new quantitative technology for diffuse histological lesion is a new and promising sonography-based noninvasive method for the assessment of liver fibrosis in patients with chronic hepatitis B.

    Full Text Available Objective: End-stage chronic liver disease (CLD adversely affects the function of multiple organ systems including the skeletal system. The aim of this study was to assess osseous and nonosseous bone scintigraphy (BS findings in liver transplant (LT candidates with end-stage CLD. Methods: We retrospectively evaluated BS findings in 50 consecutive patients with end-stage CLD who were undergoing preoperative assessment for LT from January 2006 to December 2011. All the patients were analyzed with respect to clinical and laboratory parameters, and BS findings. Scintigrams were visually assessed for the presence of osseous and nonosseous abnormalities. Osseous abnormalities were classified as those indicating bone metabolism changes or metastatic bone disease. Typical scintigraphic findings denoting to changes in bone metabolism were the presence of decreased osseous uptake, increased periarticular uptake, asymmetrical or unusual uptake patterns. Nonosseous findings were classified according to the degree of soft-tissue uptake as mild and severe. Results: The group consisted of 46 adult and 4 adolescent patients. All adolescent patients had normal skeletal accumulation with growth plate uptake and one had mildly increased renal cortical activity. A total of 46 adult patients had one or more of the following osseous findings: generalized decrease in osseous uptake (n=4, 8.7%; bilateral decrease in lower extremity uptake (n=26, 56.5%; symmetrically increased periarticular uptake (n=26, 56.5%; bilateral cortical/periosteal increased uptake in the lower extremity indicating hepatic hypertrophic osteoarthropathy (HOA (n=8, 17.4%; bilateral increased sacroiliac activity (n=16, 34.8%; sacral activity (n=10, 21.7%, coccygeal activity (n=2, 4.3%, focally increased uptake suggestive of metastases (n=5, 10.9%. Three rib metastases appeared to be linear. Nonosseous findings observed in adult patients were mild diffuse liver uptake (n=4, 8.7% and bilateral

    Chronic renal failure (CRF) is a significant cause of morbidity and mortality in post-liver transplantation (LT) recipients. The risk factors associated with the development of renal dysfunction are not clearly elucidated. To examine the risk factors in the development of CRF in these patients. Retrospective case-cohort of liver transplant patients without baseline kidney dysfunction who developed chronic renal failure during their follow-up. Of 370 patients, 254 met the inclusion criteria. 30% (76) of these patients had CRF of which 57% (43) were male. Age, estimated glomerular filtration rate (eGFR) at discharge, and HCV infection were found to be risk factors for CRF post-LT. The odds ratio of developing CRF was 1.4 (0.6-3.3) in males with HCV, 1.6 (0.7-3.9) in females without HCV and 4.4 (1.5-13.2) among females with HCV when compared to men without HCV. In this cohort of LT receipients of a major Canadian city, age, eGFR, and HCV infection were risk factors for CRF. Female gender and HCV increased this odds by a factor of more than 4.

    Serum Golgi protein 73 (GP73) is a potential biomarker for fibrosis assessment. We aimed to develop an algorithm based on GP73 and liver stiffness (LS) for further improvement of accuracy for significant fibrosis in patients with antiviral-naïve chronic hepatitis B virus (HBV) infection. Diagnostic accuracy evaluation of GP73 and development of GP73-LS algorithm was performed in training cohort (n = 267) with an independent cohort (n = 133) for validation. A stepwise increasing pattern of serum GP73 was observed across fibrosis stages in patients with antiviral-naïve chronic HBV infection. Serum GP73 significantly correlated (rho = 0.48, P 73, accuracy: 63.6%). Using GP73-LS algorithm, GP73 < 63 in agreement with LS < 8.5 provided accuracy of 81.7% to excluded significant fibrosis. GP73 ≥ 63 in agreement with LS ≥ 8.5 provided accuracy of 93.3% to confirm significant fibrosis. Almost 64% or 68% of patients in the training or validation cohort could be accurately classified. Serum GP73 is a robust biomarker for significant fibrosis diagnosis. GP73-LS algorithm provided better diagnostic accuracy than currently available approaches. More than 60% antiviral naïve CHB patients could use this algorithm without resorting to liver biopsy. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Innate lymphoid cells (ILCs) are defined as a distinct arm of innate immunity. According to their profile of secreted cytokines and lineage-specific transcriptional factors, ILCs can be categorized into the following three groups: group 1 ILCs (including natural killer (NK) cells and ILC1s) are dependent on T-bet and can produce interferon-γ; group 2 ILCs (ILC2s) are dependent on GATA3 and can produce type 2 cytokines, including interleukin (IL)-5 and IL-13; and, group 3 ILCs (including lymphoid tissue-like cells and ILC3s) are dependent on RORγt and can produce IL-22 and IL-17. Collaborative with adaptive immunity, ILCs are highly reactive innate effectors that promptly orchestrate immunity, inflammation and tissue repair. Dysregulation of ILCs might result in inflammatory disorders. Evidence regarding the function of intrahepatic ILCs is emerging from longitudinal studies of inflammatory liver diseases wherein they exert both physiological and pathological functions, including immune homeostasis, defenses and surveillance. Their overall effect on the liver depends on the balance of their proinflammatory and antiinflammatory populations, specific microenvironment and stages of immune responses. Here, we review the current data about ILCs in chronic liver disease progression, to reveal their roles in different stages as well as to discuss their therapeutic potency as intervention targets.

    Vaccinations against hepatitis A virus (HAV) and hepatitis B virus (HBV) are recommended for patients with chronic liver disease (CLD), yet implementation of these recommendations is lacking. This study reviewed HAV and HBV antibody testing and vaccination status of patients with CLD. In 2008, we began using pre-printed liver order sets, which included vaccination options. We compared Scott & White liver clinic CLD patient records from 2005 (238) with patient records from 2008 (792). Screening rates for immunity and vaccination rates of those lacking immunity were calculated. In 2005, 66% of CLD patients were screened for HAV immunity. In 2008, 56% of CLD patients were screened. The HAV vaccination completion rate was 37% in 2005, while in 2008, the rate was 46%. In 2005, 66% of CLD patients were screened for HBV immunity; in 2008, 56 % CLD patients were screened. The HBV vaccination completion rate was 26% in 2005 compared with 36% in 2008. Although there was a lower percentage of screening in 2008, the overall number of patients tripled between 2005 and 2008. There was a significant increase in the total number of patients screened and vaccinated in 2008. Some physicians may have vaccinated their patients without checking for immunity. In January 2008, we implemented pre-printed order sets with checkboxes to help remind providers to order labs to screen for immunity against HAV and HBV and to order vaccinations for those who lacked immunity. The use of these sets may have aided in the increase of vaccination completion rates.

    Chronic liver disease (CLD) is characterized by numerous metabolic alterations resulting in the clinical picture of malnutrition or even cachexia and contributing to complications such as hepatic encephalopathy and ascetics. In view of these alternations, this study was conducted to investigate the role of serum insulin-like growth factor-I (IGF-I) and ghrelin in CLD with or without cirrhosis and evaluate their relationships with liver functions and clinical complications. Serum IGF-I levels were very highly significantly lowered (P< 0.0001) in hepatitis C virus (HCV) patients and in hepatocellular carcinoma (HCC) patients than in the control group. However, serum ghrelin levels were significantly elevated in HCV and in HCC patients when compared with controls (P< 0.05). IGF-I significantly decreased with every stage of cirrhosis according to Child-Pugh classification. In contrast, serum ghrelin levels were significantly elevated in Child C liver cirrhosis compared to non cirrhotic patients (Child A and Child B cirrhosis). IGF-I levels inversely correlated with prothrombin time (PT.), total bilirubin and positively correlated with serum albumin. While serum ghrelin correlated with clinical complications of CLD. No correlations were found between IGF-I and ghrelin in all studied groups, however, both inversely correlated with a-feto protein (AFP) in HCC patients. We conclude that IGF-I.and ghrelin can predict the diagnosis and prognosis of patients with severe CLD as they have potential relationships with hepatic failure and HCC.

    Breath testing is increasingly being used as a non-invasive diagnostic tool for disease states across medicine. The purpose of this study was to compare the levels of volatile organic compounds (VOCs) as measured by mass spectrometry in healthy children and children with chronic liver disease (CLD). Patients between the ages of 6 and 21 were recruited for the study. Control subjects were recruited from a general pediatric population during well-child visits, while patients with CLD were recruited from pediatric gastroenterology clinic visits. The diagnosis of CLD was confirmed by clinical, laboratory, and/or histologic data. A single exhaled breath was collected and analyzed by means of selected-ion flow-tube mass spectrometry per protocol. A total of 104 patients were included in the study (49 with CLD and 55 healthy controls). Of the patients with CLD, 20 had advanced liver fibrosis (F3-F4). In the CLD cohort, levels of exhaled 1-decene, 1-heptene, 1-octene and 3 methylhexane were found to be significantly higher when compared to the control population (p CLD patients when compared to controls (p CLD was excellent (AUROC = 0.97). Our study demonstrates that children with CLD have a unique pattern of exhaled VOCs. Utilization of a combination of these VOCs represents a promising non-invasive diagnostic tool and may provide further insight into the pathophysiologic processes and pathways leading to pediatric liver disease. Further analysis of these compounds in external cohorts are needed to validate our findings.

    Purpose The purpose of this study was to assess whether preoperative chronic renal failure (CRF) affects the rates of postoperative complications and survival after liver transplantation. Methods This population-based retrospective cohort study included 2,931 recipients of liver transplantation performed between 1998 and 2012, enrolled from the Taiwan National Health Insurance Research Database. Patients were divided into two groups, based on the presence or absence of preoperative CRF. Results The overall estimated survival rate of liver transplantation recipients (LTRs) with preoperative CRF was significantly lower than that of patients without preoperative CRF (P=0.0085). There was no significant difference between the groups in terms of duration of intensive care unit stay, total hospital stay, bacteremia, postoperative bleeding, and pneumonia during hospitalization. Long-term adverse effects, including cerebrovascular disease and coronary heart disease, were not different between patients with versus without CRF. Conclusion These findings suggest that LTRs with preoperative CRF have a higher rate of mortality. PMID:28008264

    AIM: To test the psychometric properties of a Chinese [(Hong Kong) HK] translation of the chronic liver disease questionnaire (CLDQ). METHODS: A Chinese (HK) translation of the CLDQ was developed by iterative translation and cognitive debriefing. It was then administered to 72 uncomplicated and 78 complicated chronic hepatitis B (CHB) patients in Hong Kong together with a structured questionnaire on service utilization, and the Chinese (HK) SF-36 Health Survey Version 2 (SF-36v2). RESULTS: Scaling success was ≥ 80% for all but three items. A new factor assessing sleep was found and items of two (Fatigue and Systemic Symptoms) subscales tended to load on the same factor. Internal consistency and test-retest reliabilities ranged from 0.58-0.90 for different subscales. Construct validity was confirmed by the expected correlations between the SF-36v2 Health Survey and CLDQ scores. Mean scores of CLDQ were significantly lower in complicated compared with uncomplicated CHB, supporting sensitivity in detecting differences between groups. CONCLUSION: The Chinese (HK) CLDQ is valid, reliable and sensitive for patients with CHB. Some modifications to the scaling structure might further improve its psychometric properties. PMID:19598306

  13. Generalized Liver- and Blood-Derived CD8+ T-Cell Impairment in Response to Cytokines in Chronic Hepatitis C Virus Infection.

    Full Text Available Generalized CD8+ T-cell impairment in chronic hepatitis C virus (HCV infection and the contribution of liver-infiltrating CD8+ T-cells to the immunopathogenesis of this infection remain poorly understood. It is hypothesized that this impairment is partially due to reduced CD8+ T-cell activity in response to cytokines such as IL-7, particularly within the liver. To investigate this, the phenotype and cytokine responsiveness of blood- and liver-derived CD8+ T-cells from healthy controls and individuals with HCV infection were compared. In blood, IL-7 receptor α (CD127 expression on bulk CD8+ T-cells in HCV infection was no different than controls yet was lower on central memory T-cells, and there were fewer naïve cells. IL-7-induced signalling through phosphorylated STAT5 was lower in HCV infection than in controls, and differed between CD8+ T-cell subsets. Production of Bcl-2 following IL-7 stimulation was also lower in HCV infection and inversely related to the degree of liver fibrosis. In liver-derived CD8+ T-cells, STAT5 activation could not be increased with cytokine stimulation and basal Bcl-2 levels of liver-derived CD8+ T-cells were lower than blood-derived counterparts in HCV infection. Therefore, generalized CD8+ T-cell impairment in HCV infection is characterized, in part, by impaired IL-7-mediated signalling and survival, independent of CD127 expression. This impairment is more pronounced in the liver and may be associated with an increased potential for apoptosis. This generalized CD8+ T-cell impairment represents an important immune dysfunction in chronic HCV infection that may alter patient health.

    Background The functions of ghrelin (GHRL) include anti-inflammatory effects, reduction of the fibrogenic response, protection of liver tissue, and regulation of cell proliferation. Genetic variations in the GHRL gene may play an important role in the development of chronic hepatitis B (CHB), liver cirrhosis (LC) and hepatocellular carcinoma (HCC). Therefore, we investigated whether GHRL gene polymorphisms and its serum levels are associated with hepatitis B virus (HBV)-related diseases risk ...

    Liver-related mortality varies across developed nations. To assess the relative role of various risk factors in relation to liver-related mortality in an ecological study approach. Data for liver-related mortality, prevalence data for hepatitis B and C, human immunodeficiency virus (HIV), alcohol consumption per capita, Type 2 Diabetes mellitus (T2DM), overweight and obesity were extracted from peer-reviewed publications or WHO databases for different developed countries. As potential other risk-modifying factors, purchase power parity (PPP)-adjusted gross domestic product (GDP) per capita and health expenditure per capita were assessed. As an environmental 'hygiene factor', we also assessed the effect of the prevalence of Helicobacter pylori. Only countries with a PPP-adjusted GDP greater than $20 000 and valid information for at least 8 risk modifiers were included. Univariate and multivariate analyses were utilised to quantify the contribution to the variability in liver-related mortality. The proportion of chronic liver diseases (CLD)-related mortality ranged from 0.73-2.40% [mean 1.56%, 95% CI (1.43-1.69)] of all deaths. Univariately, CLD-related mortality was significantly associated with Hepatitis B prevalence, alcohol consumption, PPP-adjusted GDP (all P < 0.05) and potentially H. pylori prevalence (P = 0.055). Other investigated factors, including hepatitis C, did not yield significance. Backward elimination suggested hepatitis B, alcohol consumption and PPP-adjusted GDP as risk factors (explaining 66.3% of the variability). Hepatitis B infection, alcohol consumption and GDP, but not hepatitis C or other factors, explain most of the variance of liver-related mortality. © 2016 John Wiley & Sons Ltd.

    Full Text Available Abstract Background Alterations in carbohydrate metabolism are frequently observed in cirrhosis. We conducted this study to define the prevalence of diabetes mellitus (DM and impaired glucose tolerance (IGT in Iranian patients with chronic liver disease (CLD, and explore the factors associated with DM in these patients. Methods One hundred and eighty-five patients with CLD were enrolled into the study. Fasting plasma glucose and two-hour plasma glucose were measured in patients' sera. DM and IGT were diagnosed according to the latest American Diabetes Association criteria. Results The subjects included 42 inactive HBV carriers with a mean age of 42.2 ± 12.0 years, 102 patients with HBV or HCV chronic hepatitis with a mean age of 41.2 ± 10.9 years, and 41 cirrhotic patients with a mean age of 52.1 ± 11.4 years. DM and IGT were diagnosed in 40 (21.6% and 21 (11.4% patients, respectively. Univariate analysis showed that age (P = 0.000, CLD status (P = 0.000, history of hypertension (P = 0.007, family history of DM (P = 0.000, and body mass index (BMI (P = 0.009 were associated with DM. Using Multivariate analysis, age (OR = 4.7, 95%CI: 1.8–12.2, family history of DM (OR = 6.6, 95%CI: 2.6–17.6, chronic hepatitis (OR = 11.6, 95%CI: 2.9–45.4, and cirrhosis (OR = 6.5, 95%CI: 2.4–17.4 remained as the factors independently associated with DM. When patients with cirrhosis and chronic hepatitis were analyzed separately, higher Child-Pugh's score in cirrhotic patients (OR = 9.6, 95%CI: 1.0–88.4 and older age (OR = 7.2, 95%CI: 1.0–49.1, higher fibrosis score (OR = 59.5, 95%CI: 2.9–1211.3/ OR = 11.9, 95%CI: 1.0–132.2, and higher BMI (OR = 30.3, 95%CI: 3.0–306.7 in patients with chronic hepatitis were found to be associated with higher prevalence of DM. Conclusions Our findings indicate that patients with cirrhosis and chronic hepatitis are at the increased risk of DM occurrence. Older age, severe liver disease, and obesity were associated

    Obesity, a complex disease determined both by genetic and environmental factors, is strongly associated with NAFLD, and has been demonstrated to have a negative impact on HCV and other chronic liver diseases (CLD). This study assessed the association between type and location of food sources and chronic liver disease (CLD) using Geographic Information Systems (GIS). CLD patients completed surveys [267 subjects, 56.5% female, age 55.8 ± 12.0, type of CLD: 36.5% hepatitis C (HCV), 19.9% hepatitis B (HBV), 19.9% non-alcoholic fatty liver disease (NAFLD); primary food source (PFS): 80.8% grocery store, secondary: 26.2% bulk food store, tertiary: 20.5% restaurants; fresh food (FF): 83%, pre-packaged (PP) 8.7%, already prepared (AP) 8.3%]. FF consumers had significantly fewer UEH servings/month (p = 0.030) and lived further away from convenience stores (1.69 vs. 0.95 km, p = 0.0001). Stepwise regression reveals the lowest FF consumers were NAFLD patients, subjects with UEH or restaurants and ethnic food stores as their PFS (R = 0.557, p = 0.0001). Eating already-packaged foods and utilizing restaurants or ethnic food stores as the PFS positively correlated with NAFLD (R = 0.546, p = 0.0001). Environmental food source measures, including type and density, should be included when examining areas hyper-saturated with a variety of food options. In hyper-saturated food environments, NAFLD patients consume more prepared food and less FF. CLD patients with UEH also eat significantly more prepared food and frequent restaurants and ethnic food stores as their PFS.

Results The mean levels of HOMA-IR and IRI increase progressively among CHC (2.7 ± 2.9 and 11.5 ± 10.5, respectively, LC (5.4 ± 4.5 and 17.6 ± 11.2 and HCC (6.4 ± 9.8 and 18.2 ± 18.8. In the upper quintiles for HOMA-IR and IRI, the frequency of patients in the LC and HCC groups was twice as much in CHC cases. HCC with DM2 have the greatest percentage above the 80th percentile of HOMA-IR, their quintiles distribution is inverted and HOMA-IR mean values are significantly higher in comparison with HCC without DM2 cases. Discussion Our study shows that the association between IR and CLD begins in the early stages of liver fibrosis. DM2 increases HOMA-IR and IRI mean levels in HCC patients and these metabolic factors could play a major role in the link between diabetes mellitus and hepatocarcinoma.

    Full Text Available ObjectiveTo investigate the diagnostic value of real-time tissue elastography (RTE in evaluating liver fibrosis in patients with chronic hepatitis B (CHB. MethodsEighty-six patients with CHB, who visited Beijing Tiantan Hospital and Beijing You′an Hospital from March to August, 2013, were grouped according to the pathological stages of liver fibrosis. They were examined by RTE, biochemical tests, and liver biopsy. Then, liver fibrosis index (LFI and aspartate aminotransferase-to-platelet ratio index (APRI were calculated. Comparison between groups was made by one-way analysis of variance, followed by LSD t-test for multiple comparisons. The correlation between LFI and pathological stage of liver fibrosis was analyzed by Spearman correlation test. The sensitivity and specificity of LFI for the diagnosis of liver fibrosis were calculated. Regarding S≥2 (significant liver fibrosis and S≥4 (early liver cirrhosis as the positive standards, the receiver operating characteristic (ROC curve was drawn and compared with APRI. ResultsLFI differed significantly across the groups (P=0.000, except the comparison between S0 and S1 (P=0.298. LFI was significantly correlated with pathological stage (r=0.831, P<0.001. The areas under the ROC curve of LFI in diagnosing significant liver fibrosis and early liver cirrhosis were 0873 (P<0.001 and 0.923 (P=0002, respectively; the diagnostic thresholds were 2.74 and 3.61, respectively; the sensitivity and specificity were 0.766/0.872 and 0.833/0.878, respectively. LFI was significantly superior to APRI. ConclusionRTE has high diagnostic values for significant liver fibrosis and early liver cirrhosis and is an important noninvasive diagnostic method for liver fibrosis in patients with CHB.

    Portal vein thrombosis (PVT) after orthotopic liver transplantation is an infrequent complication, and when it is present surgical treatment is considered for traditional management. Percutaneous transhepatic portal vein angioplasty has been described as an option to treat PVT with a lower morbidity than conventional surgical treatments. This article describes a case of chronic PVT in a child after a living donor liver transplantation managed by percutaneous transhepatic and surgical approaches.

    The aim of this study was to validate the chronic liver failure-sequential organ failure assessment score (CLIF-SOFAs), CLIF consortium organ failure score (CLIF-C OFs), CLIF-C acute-on-chronic liver failure score (CLIF-C ACLFs), and CLIF-C acute decompensation score in Korean chronic liver disease patients with acute deterioration. Acute-on-chronic liver failure was defined by either the Asian Pacific Association for the study of the Liver ACLF Research Consortium (AARC) or CLIF-C criteria. The diagnostic performances for short-term mortality were compared by the area under the receiver operating characteristic curve. Among a total of 1470 patients, 252 patients were diagnosed with ACLF according to the CLIF-C (197 patients) or AARC definition (95 patients). As the ACLF grades increased, the survival rates became significantly lower. The areas under the receiver operating characteristic of the CLIF-SOFAs, CLIF-C OFs, and CLIF-C ACLFs were significantly higher than those of the Child-Pugh, model for end-stage liver disease, and model for end-stage liver disease-Na scores in ACLF patients according to the CLIF-C definition (all P < 0.05), but there were no significant differences in patients without ACLF or in patients with ACLF according to the AARC definition. The CLIF-SOFAs, CLIF-C OFs, and CLIF-C ACLFs had higher specificities with a fixed sensitivity than liver specific scores in ACLF patients according to the CLIF-C definition, but not in ACLF patients according to the AARC definition. The CLIF-SOFAs, CLIF-C OFs, and CLIF-C ACLFs are useful scoring systems that provide accurate information on prognosis in patients with ACLF according to the CLIF-C definition, but not the AARC definition. © 2017 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

    Full Text Available ObjectiveTo investigate the detection rate and features of autoantibodies in chronic hepatitis C (CHC patients after plasmaphoresis, as well as the liver pathological features of autoantibody-positive CHC patients. MethodsA total of 120 patients who were infected with hepatitis C virus after plasmaphoresis in the Hospital of Dingxi County and Dingxi Hospital of Infectious Diseases from January 1992 to December 1995 were selected as test group; 11 healthy people from the same region were selected as control group. Autoantibody detection was performed for the 120 CHC patients, and liver pathological features were compared between the autoantibody-positive group(n=44 and autoantibody-negative group(n=76 of these patients. The t test was used for comparison of continuous data, and the chi-square test was used for comparison of categorical data. ResultsOf all 120 CHC patients who underwent plasmaphoresis, 44 (36.7% were found to have serum autoantibodies, with antinuclear antibodies as the most common type (21.7%. Compared with the autoantibody-negative group, the autoantibody-positive group had significantly higher scores of focal necrosis inside the hepatic lobules (211±0.88 vs 164±0.88, t=2.349,P=0.021 and ductular reaction inside the portal area (1.86±0.71 vs 1.13±0.66, t=4.217,P<0.001, as well as a significantly higher rate of interlobular bile duct injury (86.4% vs 55.3%, χ2=12.129,P=0.001. There were no significant differences between the two groups in the degree of liver fibrosis and hepatic steatosis (both P>0.05. ConclusionAutoantibody-positive are common in CHC patients after plasmaphoresis, and autoantibody-positive patients tend to have more severe injuries of the liver.

    The effect of stevia on liver cirrhosis has not been previously investigated. In the present study, the antioxidant and anti-inflammatory properties of stevia leaves were studied in male Wistar rats with carbon tetrachloride- (CCl4-) induced acute and chronic liver damage. Acute and chronic liver damage induced oxidative stress, necrosis, and cholestasis, which were significantly ameliorated by stevia. Chronic CCl4 treatment resulted in liver cirrhosis, as evidenced by nodules of hepatocytes surrounded by thick bands of collagen and distortion of the hepatic architecture, and stevia significantly prevented these alterations. Subsequently, the underlying mechanism of action of the plant was analyzed. Our study for the first time shows that stevia upregulated Nrf2, thereby counteracting oxidative stress, and prevented necrosis and cholestasis through modulation of the main proinflammatory cytokines via NF-κB inhibition. These multitarget mechanisms led to the prevention of experimental cirrhosis. Given the reasonable safety profile of stevia, our results indicated that it may be useful for the clinical treatment of acute and chronic liver diseases. PMID:29849889

    Infection with hepatotropic viruses is a common cause of acute deterioration and adverse outcome in children with chronic liver disease (CLD). Such superimposed infections may be preventable through vaccination. The present study aimed to evaluate the exposure rates of hepatitis A, B, and E viruses in children with CLD and suggest an optimal vaccination strategy. Children with CLD were prospectively evaluated with a demographic, clinical, and investigative proforma. Hepatitis B surface antigen positive cases were labeled as hepatitis B virus-CLD, and all other etiologies as non-HBV-related CLD. Patients were tested for exposure to hepatitis A (total anti-hepatitis A virus [HAV], immunoglobulin M anti-HAV), hepatitis B (hepatitis B surface antigen, total anti-hepatitis B core, anti-hepatitis B surface), and hepatitis E (IgG anti-hepatitis E virus). A total of 142 children with CLD (age 9.1 ± 3.7 years, 83 [58.5%] boys) were enrolled. A total of 3.5% (5/142) and 38.7% (55/142) had received HAV and HBV vaccines, respectively. A total of 134 (94.4%) were total anti-HAV positive including 5 postimmunization patients, with higher positivity in those older than 5 years (19/25 vs 115/117; P = 0.001). Of the 115 patients with non-HBV-related CLD, 45 (39.1%) had exposure to HBV (40 total anti-hepatitis B core positive and 5 anti-HBs positive without immunization). Only 28 of 142 (19.7%) patients were IgG anti-HEV positive, with no difference across age. A total of 90.8%, 39.1%, and 19.7% of children with CLD from the developing world are exposed to hepatitis A, B, and E infections, respectively. Selective hepatitis A vaccination (patients younger than 5 years of age) and universal hepatitis B vaccination are required to protect children with CLD. Sanitation improvement and HEV vaccine trial are needed for prevention against HEV.

    To evaluate gastric emptying in patients with chronic liver disease and portal hypertension. We measured gastric emptying of both the liquid and solid components of a meal in 10 consecutive patients with chronic liver disease and portal hypertension, but free of ascites, and 14 age- and sex-matched healthy controls. In the patients with liver disease, relationships between emptying and liver function were examined. To measure gastric emptying, subjects consumed a test meal that consisted of scrambled eggs labeled with 99mTc-sulfur colloid and 4 oz of water labeled with 111In-diethylene triamine pentacetic acid (DTPA). Patients with liver disease and portal hypertension demonstrated delayed emptying of both the liquid (t1/2, min, mean +/- SE, patients vs. 69.4 +/- 19.4 vs. 31.4 +/- 1.8, p < 0.01) and solid (post-lag phase solid emptying: 141 +/- 32.9 vs. 69.8 +/- 4.6, p < 0.006) components of the meal. We could not identify any correlation between gastric emptying and tests of liver function. Gastric emptying is delayed in patients with liver disease and portal hypertension; this abnormal gastric motor function may contribute to the pathophysiology of foregut complaints in this patient population.

    Diabetes mellitus (DM) has been proposed as a risk factor for both chronic liver disease (CLD) and for hepatocellular carcinoma (HCC); however, studies among Hispanics are limited. Puerto Rico (PR) has a high prevalence of DM (13%), supporting the need for a better understanding of the public health implications associated with DM in this population. We assessed the association of DM with CLD and with HCC in a population of Puerto Rican adults with health insurance. The study sample consisted of 1,040,025 individuals, aged > or = 18 years, all covered by the government-run healthcare program in PR, in 2002. The ICD-9 codes for DM, CLD, and HCC were obtained in order to determine the prevalence of these conditions. Logistic regression models were used to determine the association of DM with CLD and with HCC, after adjusting for covariates. The prevalence of DM was higher in patients with CLD (17%) and those with HCC (18%) than it was in patients without either of these conditions (8% and 7%, respectively). Among women, those with DM were significantly more likely to have CLD than were those without DM (POR: 35-49 yrs: 3.26, 95% CI = 2.12, 5.00; POR: 50-64 yrs: 2.10, 95% CI = 1.63, 2.71; POR: > or = 65 yrs: 2.33, 95% CI = 1.67, 3.25). Among men, those with DM were more likely to have CLD than were those without DM; this association was significant among males aged 50-64 (POR: 1.30, 95% CI = 1.03-1.63) and those aged > or = 65 yrs (POR: 1.94, 95% CI = 1.35-2.80). Consistent with other studies, we observed a strong association of DM with CLD and HCC. In order to reduce the burden of these conditions in PR, research and public health efforts should be concentrated on gaining a better understanding of these associations.

    Evaluation of the liver for focal lesions is extremely important because the liver is one of the most common sites for metastatic disease. Most patients with metastatic deposits to the liver have a survival rate of about 6 months. Thus, metastatic disease to the liver has an extremely grave prognosis. In the past patients with hepatic lesions had no therapeutic recourse. However, with recent aggressive surgical advances (such as partial hepatectomies) and hepatic artery embolization, survival of patients with hepatic metastases has increased. Thus it is important for noninvasive imaging not only to detect lesions early in their course, but also to give their true hepatic involvement and the extent of the neoplastic process elsewhere in the body. Recent advances in imaging have been rapidly changing over the past 5 years. These changes have been more rapid in computed tomography (CT) and ultrasound than in radionuclide imaging. Thus, the question addressed in this chapter is: What is the relationship of hepatic ultrasound to the other current diagnostic modalities in detecting metastatic liver disease and other focal liver lesions? Also, what is its possible future relationship to nuclear magnetic resonance?

    In current societies, the risk of toxic liver damage has markedly increased. The aim of the present work was to carry out further research into the mechanism(s) of liver mitochondrial damage induced by acute (0.8 g/kg body weight, single injection) or chronic (1.6 g/ kg body weight, 30 days, biweekly injections) carbon tetrachloride – induced intoxication and to evaluate the hepatoprotective potential of the antioxidant, melatonin, as well as succinate and cranberry flavonoids in rats. Acute intoxication resulted in considerable impairment of mitochondrial respiratory parameters in the liver. The activity of mitochondrial succinate dehydrogenase (complex II) decreased (by 25%, p < 0.05). Short-term melatonin treatment (10 mg/kg, three times) of rats did not reduce the degree of toxic mitochondrial dysfunction but decreased the enhanced NO production. After 30-day chronic intoxication, no significant change in the respiratory activity of liver mitochondria was observed, despite marked changes in the redox-balance of mitochondria. The activities of the mitochondrial enzymes, succinate dehydrogenase and glutathione peroxidase, as well as that of cytoplasmic catalase in liver cells were inhibited significantly. Mitochondria isolated from the livers of the rats chronically treated with CCl{sub 4} displayed obvious irreversible impairments. Long-term melatonin administration (10 mg/kg, 30 days, daily) to chronically intoxicated rats diminished the toxic effects of CCl{sub 4}, reducing elevated plasma activities of alanine aminotransferase and aspartate aminotransferase and bilirubin concentration, prevented accumulation of membrane lipid peroxidation products in rat liver and resulted in apparent preservation of the mitochondrial ultrastructure. The treatment of the animals by the complex of melatonin (10 mg/kg) plus succinate (50 mg/kg) plus cranberry flavonoids (7 mg/kg) was even more effective in prevention of toxic liver injury and liver mitochondria damage

    Full Text Available Antioxidant effect of dietary soapwort extract supplementation was studied in growing Japanese quails suffering from chronic intermittent cold stress. For this purpose, a total of ninety 15-d-old quails were divided into three groups with three replicates. Chronic intermittent cold stress was applied every night between 22.00 to 06.00 h; starting at 14 °C for the first week, and gradually weekly lowered to 8 °C. Three groups were fed with corn-soy based standard diets supplemented with 0, 50, and 100 ppm soapwort extract for four weeks. At the end of the study, three males and three females were slaughtered to determine total antioxidant and oxidant status of serum, malondialdehyde, glutathione, glutathione peroxidase activity, superoxide dismutase of liver and heart tissues. Although the dietary soapwort extract had no effect on serum total antioxidant capacity, it significantly lowered the total oxidant status of serum in cold stressed quails. Glutathione and superoxide dismutase enzyme activity of liver and heart tissues were similar among groups. While the dietary soapwort extract had no effect on glutathione peroxidase activity of the heart tissue, it significantly increased glutathione peroxidase activity in the liver tissue. In relation to the control group, malondialdehyde concentrations in the liver and heart tissues were significantly lower in soapwort extract groups. These data suggest that dietary soapwort extract could alleviate the detrimental effects of oxidative stress in growing Japanese quails exposed to cold stress.

    Defects in lysosome function and autophagy contribute to pathogenesis of alcoholic liver disease. We investigated the mechanisms by which alcohol consumption affects these processes, evaluating the functions transcription factor EB (TFEB), which regulates lysosomal biogenesis. We performed studies with GFP-LC3 mice, mice with liver-specific deletion of transcription factor EB (TFEB), mice with disruption of the transcription factor E3 gene (TFE3-knockout mice), mice with disruption of the Tefb and Tfe3 genes (TFEB, TFE3 double-knockout mice), and Tfeb flox/flox albumin cre-negative mice (controls). TFEB was overexpressed from adenoviral vectors or knocked down with small interfering RNAs in mouse livers. Mice were placed on diets of chronic ethanol feeding plus an acute binge to induce liver damage (ethanol diet); some mice were also given injections of torin1, an inhibitor of the kinase activity of the mechanistic target of rapamycin (mTOR). Liver tissues were collected and analyzed by immunohistochemistry, immunoblots, and quantitative real-time PCR to monitor lysosome biogenesis. We analyzed levels of TFEB in liver tissues from patients with alcoholic hepatitis and from healthy donors (controls) by immunohistochemistry. Liver tissues from mice on the ethanol diet had lower levels of total and nuclear TFEB, compared with control mice, and hepatocytes had reduced lysosome biogenesis and autophagy. Hepatocytes from mice on the ethanol diet had increased translocation of mTOR into lysosomes, resulting increased mTOR activation. Administration of torin1 increased liver levels of TFEB and reduced steatosis and liver injury induced by ethanol. Mice that overexpressed TFEB in liver developed less-severe ethanol-induced liver injury and had increased lysosomal biogenesis and mitochondrial bioenergetics compared to mice carrying a control vector. Mice with knockdown of TFEB, as well as TFEB, TFE3 double-knockout mice, developed more severe liver injury in response to the

    The objective of the present study was to investigate the effects of grape seed extract (GSE) supplementation on oxidative stress and antioxidant defense markers in liver tissue of acutely and chronically exercised rats. Rats were randomly assigned to six groups: Control (C), Control Chronic Exercise (CE), Control Acute Exercise (AE), GSE-supplemented Control (GC), GSE-supplemented Chronic Exercise(GCE) and GSE-supplemented Acute Exercise (GAE). Rats in the chronic exercise groups were subjected to a six-week treadmill running and in the acute exercise groups performed an exhaustive running. Rats in the GSE supplemented groups received GSE (100 mg.kg(-1) .day(-1) ) in drinking water for 6 weeks. Liver tissues of the rats were taken for the analysis of malondialdehyde (MDA), nitric oxide (NO) levels and total antioxidant activity (AOA) and xanthine oxidase (XO) activities. MDA levels decreased with GSE supplementation in control groups but increased in acute and chronic exercise groups compared to their non-supplemented control. NO levels increased with GSE supplementation. XO activities were higher in AE group compared to the CE group. AOA decreased with GSE supplementation. In conclusion, while acute exercise triggers oxidative stress, chronic exercise has protective role against oxidative stress. GSE has a limited antioxidant effect on exercise-induced oxidative stress in liver tissue.

  15. Anxiety and Related Factors in Chronic Pain

    Full Text Available Clinicians often encounter patients who present with both chronic pain and elevated levels of anxiety. In some cases, the source of the anxiety is vague and diffuse. For others, there is an identifiable precipitating object, event or situation. For example, some patients with chronic pain are able to attribute their anxiety to the possibility of not regaining lost functional abilities, financial difficulties, feelings of social inadequacy, or uncertainty about the meaning and consequences of pain. The association between chronic pain and anxiety may not be particularly surprising when one considers that, in the acute phase, both pain and target-oriented anxiety (or fear motivate actions that serve to minimize the threat and maximize the likelihood of successful escape.

    Among the histological lesions seen in chronic hepatitis C (CHC), the presence of steatosis, bile duct lesions and lymphoid aggregates are characteristic. Recent reports suggest that steatosis is an independent risk factor for liver fibrosis in CHC. The aim of our study was to determine the relative contribution of steatosis and moderate alcohol consumption to the severity of liver fibrosis in patients infected with genotype 1 hepatitis C virus. We evaluated the patients with biopsy proven CHC and no or only moderate alcohol intake (<40 g/day). The demographical parameters of the study population, the indices of alcohol consumption: erythrocyte median corpuscular volume (MCV), gamma-glutamyl transpeptidase (GGT), the histological characteristics were noted and a statistical analysis was performed in order to determine the factors independently associated with severe fibrosis and with severe steatosis. From the 200 patients included in the study, 82 were males and 118 females, with a mean age of 47.75+/-10.42 years. At univariate analysis, advanced (grade 2, 3) fibrosis correlated with: the age at the time of biopsy, increased inflammatory activity (HAI), moderate/severe steatosis, alcohol intake, elevated GGT and MCV values. After multivariate logistic regression only age, HAI and steatosis were independently associated with advanced fibrosis stage. Regarding hepatic steatosis, from the factors found to correlate with severe steatosis at univariate analysis (alcohol intake, elevated GGT and MCV levels, severe fibrosis), after multivariate logistic regression only the elevated level of GGT was an independent prognostic factor for severe steatosis. Steatosis is an important risk factor for the severity of liver disease in CHC patients. Among patients with genotype 1 hepatitis C virus infection and moderate alcohol intake, those with serum levels of GGT over two times the normal value are at high risk for severe steatosis.

    Hospice offers non-curative symptomatic management to improve patients' quality of life, satisfaction, and resource utilization. Hospice enrollment among patients with chronic liver disease (CLD) is not well studied. The aim of tis tudy is to examine the characteristics of Medicare enrollees with CLD, who were discharged to hospice. Medicare patients discharged to hospice between 2010 and 2014 were identified in Medicare Inpatient and Hospice Files. CLDs and other co-morbidities were identified by International Classification of Diseases-ninth revision codes. Generalized linear model was used to estimate regression coefficients with P-values. Logistic regression was used to calculate odds ratios and 95% confidence intervals. A total of 2,179 CLD patients and 34,986 controls without CLD met the inclusion criteria. Non-alcoholic fatty liver disease, alcoholic liver disease, and hepatitis C virus (HCV) were the most frequent cause of CLD. CLD patients were younger (70 vs. 83 years), more likely to be male (57.7 vs. 39.3%), had longer hospital stay (length of stay, LOS) (19.4 vs. 13.0 days), higher annual charges ($175,000 vs. $109,000), higher 30-day re-hospitalization rates (51.6 vs. 34.2%), and shorter hospice LOS (13.7 vs. 17.7 days) than controls (all PCLD have longer and costly hospitalizations before hospice enrollment as compared with patients without CLD. It was highly likely that these patients were enrolled relatively late, which could potentially lead to less benefit from hospice.

    The relationship between chronic pancreatitis (CP) and subsequent pyogenic liver abscess (PLA) is not well understood. We investigated the risk of PLA in patients with CP using inpatient claims data from the Taiwan National Health Insurance Program for the period 2000-2010. We identified 17,810 patients with chronic pancreatitis (CP group) and 71,240 patients without CP (non-CP group). Both cohorts were followed until a diagnosis of PLA, until they were censored from the study because of loss to follow-up, death, or termination of insurance, or until the study cut-off date of 31 December 2011. Incidence and risk factors for development of PLA, and the effects of comorbidities, were assessed. The incidence of PLA in the CP group was 12.9 times that in the non-CP group (38.3 vs. 2.89 events per 1000 person-years; 95% confidence interval [CI], 10.5-15.8). After adjusting for age, sex, and the comorbidities of hypertension, diabetes, hyperlipidemia, cerebral vascular accident, cirrhosis, heart failure, chronic obstructive pulmonary disease, chronic kidney disease, cancer, alcoholism, other diseases of the pancreas, cholecystitis, and cholelithiasis and other disorders of the biliary tract and endoscopic insertion of stent (tube) into the bile duct, the risk of PLA remained higher among CP patients than among the comparison cohort (adjusted hazard ratio, 6.40; 95% CI, 4.83-8.49). CP patients with five or more comorbidities had a significantly higher risk of PLA (adjusted hazard ratio, 24.9; 95% CI, 18.3-33.8). CP was associated with increased risk of subsequent PLA. The risk of PLA was higher in patients with five or more comorbidities.

    Full Text Available Restraint and cold stress increase both corticosterone and glycemia, which lead to oxidative damages in hepatic tissue. This study assessed the effect of royal jelly (RJ supplementation on the corticosterone level, glycemia, plasma enzymes and hepatic antioxidant system in restraint and cold stressed rats. Wistar rats were allocated into no-stress, stress, no-stress supplemented with RJ and stress supplemented with RJ groups. Initially, RJ (200mg/Kg was administered for fourteen days and stressed groups were submitted to chronic stress from the seventh day. The results showed that RJ supplementation decreases corticosterone levels and improves glycemia control after stress induction. RJ supplementation also decreased the body weight, AST, ALP and GGT. Moreover, RJ improved total antioxidant capacity, SOD activity and reduced GSH, GR and lipoperoxidation in the liver. Thus, RJ supplementation reestablished the corticosterone levels and the hepatic antioxidant system in stressed rats, indicating an adaptogenic and hepatoprotective potential of RJ.

    Interferon (IFN) provides effective treatment in some patients with chronic hepatitis. The clarification of factors predictive of therapy response would be helpful in identifying patients who would benefit from treatment. In this study, we evaluated the potential utility of Tc-99m sulfur colloid liver/spleen and Tc-99m-disofenin hepatobiliary scintigraphy to predict therapy response to IFN in patients with chronic active hepatitis. The study group consisted of ten patients with chronic viral hepatitis B who were treated with 4.5 units of interferon alpha for 12 months. Prior to the start of the therapy, sulfur colloid scintigraphy was obtained by which the liver/spleen ratios were derived. Hepatobiliary scintigraphy was performed on a separate day and time-activity curves were generated from regions of interest drawn over the liver, heart and gall-bladder. The index of blood and liver clearance time was calculated. Histological grading and laboratory values were obtained for clinical correlation. Responders (n=6) to IFN were defined as those who improved clinically with normalized transaminase levels and had hepatitis B envelope antigen (HBeAg) seroconversion. On sulfur colloid (SC) scintigraphy, the liver/spleen ratio of non-responders was significantly lower than responders (median values: 0.69 vs. 1.16, p=0.01) but on hepatobiliary scintigraphy no statistically significant parameters were found to predict response to interferon therapy.

    We evaluated the test performance profile (TPP) of blood tests of liver fibrosis. Three hundred and fifty-six patients with C chronic hepatitis were included in two centers. Metavir staging of liver specimens by two independent pathologists and the following tests were evaluated: Fibrotest (FT), APRI, FibroMeter (FM), and Hepascore (HS). Metavir stages were: F0: 4%, F1: 55%, F2: 26%, F3: 11%, and F4: 4%. The AUROCs were not significantly different, respectively, FT, FM, APRI, HS: >or=F2: 0.79, 0.78, 0.76, >or=0.76; F3: 0.81, 0.85, 0.81, 0.81; and F4: 0.86, 0.94, 0.92, 0.89. The TPP relies on the paired comparison of blood-test misclassification based on liver specimen, e.g. FT vs FM, respectively: F0+1: 18 vs 28% (p=0.0003), >or=F2: 43 vs 31% (p=0.004). There was no center effect. In those populations, the four blood tests had a similar performance for significant fibrosis (F>or=2), lying in the lower range of published results which is attributable to a low >or=F2 prevalence, and for >or=F3 and F4. However, FM and FT had performance profiles significantly different as a function of fibrosis stages or diagnostic target (fibrosis cut-off). This has to be considered during the interpretation process. Moreover, the performance should be reported with different diagnostic targets.

    The main aim of the present study was to assess the effects of chronic high stocking density on liver proteome of rainbow trout. Rainbow trout juveniles (42.6 ± 2.3 g average body weight) were randomly distributed into six tanks at two stocking densities (low stocking density (LD) = 20 kg m -3 and high stocking density (HD) = 80 kg m -3 ). Both treatments were performed in triplicate tanks for a period of 60 days. High stocking density caused a reduction in the growth performance compared with LD fish. Lysozyme activity increased with stocking density, while serum complement activity presented the opposite pattern. Serum cortisol and total protein levels did not show significant differences (P > 0.05) between experimental groups. The fish reared at high stocking density showed significantly lower osmolality and globulin values but higher albumin level. The HD group had significantly higher activities of catalase, glutathione peroxidase and superoxide dismutase, and malondialdehyde content in the liver when compared to the LD group. Comparative proteomics was used to determine the proteomic responses in livers of rainbow trout reared at high stocking density for 60 days. Out of nine protein spots showing altered abundance (>1.5-folds, P < 0.05), eight spots were successfully identified. Two proteins including apolipoprotein A-I-2 precursor and mitochondrial stress-70 protein were found to increase in HD group. The spots found to decrease in the HD group were identified as follows: 2-peptidylprolyl isomerase A, two isoforms of glyceraldehydes-3-phosphate dehydrogenase, an unnamed protein product similar to fructose-bisphosphate aldolase, 78 kDa glucose-regulated protein, and serum albumin 1 protein.

    Background: The detection rate of hepatic falciform ligament artery (FLA) has been reported as ranging from 2-25%. The rate of FLA on laparotomy, however, is reported to be higher, at 68%. Purpose: To compare the detection rate of FLA on computed tomography hepatic arteriography (CTHA) with that on angiography and dynamic CT, and to clarify the clinical significance of FLA in patients with chronic liver disease. Material and Methods: 126 consecutive patients underwent CTHA angiography and dynamic CT to evaluate suspected liver tumors. Liver function was classified as follows: normal, n=5; Child-Pugh class A, n=94; B, n=21; and C, n=6. All CT images were obtained using multidetector (MDCT) scanners (Aquilion; Toshiba, Tokyo (JP)). For CTHA, CT images were obtained during contrast material injection through the left hepatic, proper, or common hepatic artery. On CT, FLAs were retrospectively identified within the hepatic falciform ligament and the hepatic round ligament by the paging method on a workstation (TWS-5000; Toshiba, Tokyo (JP)). The detection rates were compared among the three modalities (hepatic arterial phase of dynamic CT, CTHA, and angiography). The calibers of FLA were also correlated with the hepatic function of the patients. Results: The detection rates of FLA by angiography, dynamic CT, and CTHA were 37% (47/126), 10% (13/126), and 77% (97/126), respectively. The calibers of FLA increased as the hepatic function deteriorated (P=0.001). Conclusion: The detection rates of FLA with CTHA are far higher than those with angiography and dynamic CT. Careful interpretation with recognition of FLA on CTHA images is important, as inadvertent embolization or chemotherapeutic infusion of the FLA may result in supraumbilical skin rash

    Hepatitis C virus (HCV) infection frequently leads to chronic liver disease, which adversely affects the quality of life (QoL) of the patient. The gender of the patient may be an important variable in the way severity of the disease is perceived. The aim of our study is to evaluate the effect of the gender variable on QoL in HCV-positive patients. This study included a total of 52 patients (26 men and 26 women) who completed a 1-year follow-up after liver transplantation. QoL was assessed using the SF-36 questionnaire. Male subjects have significantly higher scores on physical role functioning, bodily pain and physical activity compared with females. Females have a better QoL compared to males with regard to the emotional state and mental health. These results show a significant effect of the gender variable on QoL in HCV patients. © 2013 S.

    Data on markers of hepatitis C virus (HCV) disease in HIV-HCV co-infected patients in resource-limited settings are scarce. We assessed HCV-RNA, HCV genotype (GT), IL28B GT, and liver fibrosis (FibroScan®) in 480 HIV-infected patients with positive HCV antibody in four HIV treatment centers in South East Asia. We enrolled 165 (34.4%) patients in Jakarta, 158 (32.9%) in Bangkok, 110 (22.9%) in Hanoi, and 47 (9.8%) in Kuala Lumpur. Overall, 426 (88.8%) were male, the median (IQR) age was 38.1 (34.7–42.5) years, 365 (76.0%) reported HCV exposure through injecting drug use, and 453 (94.4%) were on combination antiretroviral therapy. The median (IQR) CD4 count was 446 (325–614) cells/mm3 and 208 (94.1%) of 221 patients tested had HIV-1 RNA F4). One patient (0.3%) had FibroScan® failure. A high proportion of HIV-HCV co-infected patients had chronic HCV infection. HCV GT1 was predominant, and 62% of patients had liver disease warranting prompt treatment (>=F2). PMID:27917597

    To assess the impact of chronic liver disease (CLD) on ICU-acquired pneumonia. This was a prospective, observational study of the characteristics, microbiology, and outcomes of 343 consecutive patients with ICU-acquired pneumonia clustered according to the presence of CLD. Sixty-seven (20%) patients had CLD (67% had liver cirrhosis, LC), MELD score 26 ± 9, 20% Child-Pugh class C). They presented higher severity scores than patients without CLD both on admission to the ICU (APACHE II, LC 19 ± 6 vs. other CLD 18 ± 6 vs. no CLD 16 ± 6; p CLD patients. LC patients had higher 28- and 90-day mortality (63 vs. 28%, p CLD patients. Presence of LC was independently associated with decreased 28- and 90-day survival (95% confidence interval [CI], 1.982-17.250; p = 0.001; 95% confidence interval [CI], 2.915-20.699, p = 0.001, respectively). In critically ill patients with ICU-acquired pneumonia, CLD is associated with a more severe clinical presentation and poor clinical outcomes. Moreover, LC is independently associated with 28- and 90-day mortality. The results of this study are important for future trials focused on mortality.

    2013-01-01

    Objectives: To assess the accuracy of platelets, platelet morphological parameters, mean platelet volume(MPV) and platelet distribution width, (PDW) to diagnose advanced fibrosis. Study Design: Validation study. Place and Duration of Study: Combined Military Hospital, Malir, from Jun 2008 to Jun 2009. Patients and Methods: Simple laboratory tests, aspartate aminotransferase (AST) alanine aminotransferase (ALT) platelet count and platelet morphological parameters were measured in 91 chronic viral hepatitis patients. All patients had liver biopsy performed. A new index, PDW index was derived to detect the opposing effects of liver fibrosis on platelet count, MPV, and PDW. The predictive value of the index for advanced fibrosis (F3-F4) was assessed through descriptive statistics and area under the ROC curves. Results: Two cut-offs were chosen to qualify different stages of fibrosis. A value of > 8.00 predicted advanced fibrosis, F3-F4, with a specificity of 94% and positive predictive value of 78%. A value of < 6.00 ruled out advanced fibrosis with a negative predictive value of 93% and a sensitivity of 82%. The area under the ROC curve for advanced fibrosis was 0.840. PDW Index values outside of these cut-offs correctly classified 60% of patients. Conclusion: A simple index comprising platelet as only parameters have high diagnostic value for the advanced stages of fibrosis. (author)

    Background/Aims Liver stiffness (LS) measurement by means of transient elastography (TE) is accurate to predict fibrosis stage. The effect of antiviral treatment and virologic response on LS was assessed and compared with untreated patients with chronic hepatitis C (CHC). Methods TE was performed at baseline, and at weeks 24, 48, and 72 in 515 patients with CHC. Results 323 treated (62.7%) and 192 untreated patients (37.3%) were assessed. LS experienced a significant decline in treated patients and remained stable in untreated patients at the end of study (P<0.0001). The decline was significant for patients with baseline LS ≥ 7.1 kPa (P<0.0001 and P 0.03, for LS ≥9.5 and ≥7.1 kPa vs lower values, respectively). Sustained virological responders and relapsers had a significant LS improvement whereas a trend was observed in nonresponders (mean percent change −16%, −10% and −2%, for SVR, RR and NR, respectively, P 0.03 for SVR vs NR). In multivariate analysis, high baseline LS (P<0.0001) and ALT levels, antiviral therapy and non-1 genotype were independent predictors of LS improvement. Conclusions LS decreases during and after antiviral treatment in patients with CHC. The decrease is significant in sustained responders and relapsers (particularly in those with high baseline LS) and suggests an improvement in liver damage. PMID:23082200

    Full Text Available Chronic graft-versus-host-disease (cGvHD is a serious complication of allogeneic hematopoietic stem cell transplantation (allo-HSCT. Among various organ-specific cGvHD, the cGvHD of liver is less well-characterized. In this study, we applied the National Institutes of Health 2014 scoring criteria of cGvHD to analyze a retrospective cohort of 362 allo-HSCT recipients focusing on cGvHD of liver. The overall incidence of liver cGvHD with a score of 3 by 1.5 years post-transplant was 5.8% (21/362. Poor outcome, in terms of overall survival (OS, were observed in patients with scores of 3 liver cGvHD, comparing to those with scores less than 3 (hazard ratio [HR] 2.037, 95% confidence interval [CI] 1.123-3.696, P = 0.019. In multivariate analysis, male gender (HR 4.004, P = 0.042 and chronic hepatitis C virus (HCV infection status (HR 19.087, P < 0.001 were statistically significant risk factors for scores of 3 liver cGvHD. Our results indicate that liver cGvHD with scores of 3 has a grave prognosis following allo-HSCT, and that HCV carrier status and male are risk factors. Early recognition of this devastating complication might help in prompt immunosuppressive therapy and reducing late poor outcome.

    In spite of the high incidence of hepatic encephalopathy (HE) in cirrhosis, there are few observational studies. We performed an analysis to define the characteristics of HE and associated features using the database of the Canonic Study. Clinical, laboratory and survival data of 1348 consecutive cirrhotic patients admitted with an acute decompensation were compared according to the presence (n=406) or absence of HE and of acute-on-chronic liver failure (ACLF) (n=301). HE development was independently associated with previous HE episodes; survival probabilities worsen in relation to the presence and grade of HE. There were marked differences between HE associated (n=174) and not associated (n=286) to ACLF. HE not associated with ACLF occurred in older cirrhotics, inactive drinkers, without severe liver failure or systemic inflammatory reaction and in relation to diuretic use. In contrast, HE associated with ACLF occurred in younger cirrhotics, more frequently alcoholics, with severe liver failure and systemic inflammatory reaction, and in relation to bacterial infections, active alcoholism and/or dilutional hyponatremia. Prognosis was relatively preserved in the first and extremely poor in the second group. Independent risk factors of mortality in patients with HE were age, bilirubin, INR, creatinine, sodium, and HE grade. In cirrhosis, previous HE identifies a subgroup of patients that is especially vulnerable for developing new episodes of HE. The course of HE appears to be different according to the presence of ACLF. Copyright © 2013 European Association for the Study of the Liver. Published by Elsevier B.V. All rights reserved.

    Parvovirus B19 infection is associated with a broad spectrum of clinical manifestations among which some are well known but others remain controversial. The role of this infection as a cause of acute hepatitis or exacerbation of chronic liver disease requires discussion regarding its significance in a strategy of prevention and treatment of patients with chronic hepatitis. Clinical importance of this infection in patients with chronic hepatitis B treated with pegylated interferon alpha 2a is still unclear but exactly in this population significant complications during treatment may arise. Parvovirus B19 infection is not rare among persons with chronic hepatitis B, therefore searching for co-infection should be placed in standard diagnostic procedures especially in case of exacerbation of chronic hepatitis, pancytopaenia or anaemia of unknown origin. Pegylated interferon alpha 2a still remains a gold standard of therapy of patients with chronic hepatitis B according to European (EASL) and Polish guidelines. We present a case of 35 years old woman treated with pegylated interferon alpha 2a who developed acute liver failure in 23rd week of chronic hepatitis B therapy. An exacerbation of hepatitis with encephalopathy and pancytopaenia have been observed. Parvovirus B19 and HBV co-infection does not increase the frequency of liver function abnormalities in patients with chronic hepatitis B. Further investigations should be done to describe the natural course of co-infection with parvovirus B19 and HBV and to establish possible association between parvovirus B19 infection and chronic hepatitis B and also the influence of interferon alpha 2a on the infections course.

    Hepatocellular carcinoma (HCC) and chronic liver disease (CLD) are major causes of morbidity and mortality among Hispanics. Disparities in the incidence of HCC and in CLD deaths by nativity in Hispanics have been reported. Whether individual-level risk factors could explain these disparities was assessed in a prospective study of 36,864 Hispanics (18,485 US-born and 18,379 foreign-born) in the Multiethnic Cohort. Risk factors were assessed with a baseline questionnaire and Medicare claim files. During a 19.6-year follow-up, 189 incident cases of HCC and 298 CLD deaths were identified. The HCC incidence rate was almost twice as high for US-born Hispanic men versus foreign-born Hispanic men (44.7 vs 23.1), but the rates were comparable for women (14.5 vs 13.4). The CLD mortality rate was about twice as high for US-born Hispanics versus foreign-born Hispanics (66.3 vs 35.1 for men and 42.2 vs 19.7 for women). Heavy alcohol consumption was associated with HCC and CLD in foreign-born individuals, whereas the current smoking status, hepatitis B/C viral infection, and diabetes were associated with both HCC and CLD. After adjustments for these risk factors, the hazard rate ratios for HCC and CLD death were 1.58 (95% confidence interval, 1.00-2.51) and 1.85 (95% confidence interval, 1.25-2.73), respectively, for US-born Hispanics versus foreign-born Hispanics. US-born Hispanics, particularly males, are at greater risk for HCC and death from CLD than foreign-born Hispanics. Overall known differences in risk factors do not account for these disparities. Future studies are warranted to identify factors that contribute to the elevated risk of HCC development and CLD death in US-born Hispanics.

    Since hepatitis C virus therapy is typically prioritized for patients with more advanced disease, predicting which patients will progress could help direct scarce resources to those likely to benefit most. This study aims to identify demographics and clinical characteristics associated with high healthcare resource utilization (HRU) and liver disease progression among CHC patients. Using health insurance claims (January 2001-March 2013), adult patients with ≥2 CHC claims (ICD-9-CM: 070.44 or 070.54), and ≥6 months of continuous insurance coverage before and ≥36 months after the first CHC diagnosis were included. Patients with human immunodeficiency virus were excluded. Generalized estimating equations were used to identify the demographic and clinical characteristics of being in the 20% of patients with the highest HRU. Factors predicting liver disease progression were also identified. In the study population (n = 4898), liver disease severity and both CHC- and non-CHC-related comorbidities and conditions were strong predictors of high healthcare costs, with odds ratios (ORs; 95% confidence interval [CI]) for ≥2 CHC-related and ≥2 non-CHC-related comorbidities/conditions of 2.78 (2.48-3.12) and 2.19 (1.76-2.72), respectively. CHC- and non-CHC-related comorbidities and conditions were also strong predictors of liver disease progression with ORs (95% CI) for ≥2 CHC-related and ≥2 non-CHC-related comorbidities and conditions of 2.18 (1.83-2.60) and 1.50 (1.14-1.97), respectively. Potential inaccuracies in claims data, information or classification bias, and findings based on a privately insured population. This study suggests that CHC patients with high healthcare resource utilization have a high level of comorbidity at baseline and also that non-CHC comorbidities and conditions are strong predictors of high HRU. Non-cirrhotic CHC patients with one or more comorbidities are at high risk of progressing to cirrhosis or end-stage liver disease.

    This study aimed to evaluate the changes in spleen and liver diffusion-weighted magnetic resonance imaging (DWI) in chronic viral hepatitis patients. The study comprised 47 patients and 30 healthy volunteers. DWIs were obtained. Apparent Diffusion Coefficient (ADC) measurements were made by transferring the images to the workstation. The measurements of value b 1000 were made from a total of five points of the liver and three points of the spleen. Liver biopsy was performed on the 47 patients. The fibrosis stages of the patients were defined according to the METAVIR scoring system. Student's t-test was used in the comparison of mean ages, liver and spleen ADC values between the patient and the control group. Kruskal–Wallis followed by Mann–Whitney U Test with Bonferroni adjustment was performed in the comparison of mean ADC values of the patients at different stages and the control group. A statistically significant difference was determined between the patient and control group in respect of liver and spleen mean ADC values (P < 0.05). F3 group showed a significant difference compared to control and F1 and F4 group showed a significant difference compared to control, F1, F2 and F3 group in terms of the mean liver ADC value (P < 0.01). F3 and F4 group showed a significant difference compared to control and F1 group in terms of the mean spleen ADC value (P < 0.01). As a result we believe that the measurement of liver and spleen ADC values may be an indicator in the determination of the level of fibrosis.

    In current societies, the risk of toxic liver damage has markedly increased. The aim of the present work was to carry out further research into the mechanism(s) of liver mitochondrial damage induced by acute (0.8 g/kg body weight, single injection) or chronic (1.6 g/ kg body weight, 30 days, biweekly injections) carbon tetrachloride – induced intoxication and to evaluate the hepatoprotective potential of the antioxidant, melatonin, as well as succinate and cranberry flavonoids in rats. Acute intoxication resulted in considerable impairment of mitochondrial respiratory parameters in the liver. The activity of mitochondrial succinate dehydrogenase (complex II) decreased (by 25%, p 4 displayed obvious irreversible impairments. Long-term melatonin administration (10 mg/kg, 30 days, daily) to chronically intoxicated rats diminished the toxic effects of CCl 4 , reducing elevated plasma activities of alanine aminotransferase and aspartate aminotransferase and bilirubin concentration, prevented accumulation of membrane lipid peroxidation products in rat liver and resulted in apparent preservation of the mitochondrial ultrastructure. The treatment of the animals by the complex of melatonin (10 mg/kg) plus succinate (50 mg/kg) plus cranberry flavonoids (7 mg/kg) was even more effective in prevention of toxic liver injury and liver mitochondria damage. Highlights: ► After 30-day chronic CCl 4 intoxication mitochondria displayed considerable changes. ► The functional parameters of mitochondria were similar to the control values. ► Melatonin + succinate + flavonoids prevented mitochondrial ultrastructure damage. ► The above complex enhanced regenerative processes in the liver.

    OBJECTIVE: To examine if monocyte and macrophage activity may be on the mechanistic pathway to non-AIDS comorbidity by investigating the associations between plasma-soluble CD163 (sCD163) and incident non-AIDS comorbidities in well treated HIV-infected individuals. DESIGN: Prospective single...... was examined using multivariable Cox proportional hazards models adjusted for pertinent covariates. RESULTS: In HIV-1-infected individuals (n = 799), the highest quartile of plasma sCD163 was associated with incident chronic lung disease [adjusted hazard ratio (aHR), 3.2; 95% confidence interval (CI): 1.34; 7.......46] and incident chronic kidney disease (aHR, 10.94; 95% CI: 2.32; 51.35), when compared with lowest quartiles. Further, (every 1 mg) increase in plasma sCD163 was positively correlated with incident liver disease (aHR, 1.12; 95% CI: 1.05; 1.19). The sCD163 level was not associated with incident cancer...

  5. A New Mouse Model That Spontaneously Develops Chronic Liver Inflammation and Fibrosis.

    Directory of Open Access Journals (Sweden)

    Nina Fransén-Pettersson

    Full Text Available Here we characterize a new animal model that spontaneously develops chronic inflammation and fibrosis in multiple organs, the non-obese diabetic inflammation and fibrosis (N-IF mouse. In the liver, the N-IF mouse displays inflammation and fibrosis particularly evident around portal tracts and central veins and accompanied with evidence of abnormal intrahepatic bile ducts. The extensive cellular infiltration consists mainly of macrophages, granulocytes, particularly eosinophils, and mast cells. This inflammatory syndrome is mediated by a transgenic population of natural killer T cells (NKT induced in an immunodeficient NOD genetic background. The disease is transferrable to immunodeficient recipients, while polyclonal T cells from unaffected syngeneic donors can inhibit the disease phenotype. Because of the fibrotic component, early on-set, spontaneous nature and reproducibility, this novel mouse model provides a unique tool to gain further insight into the underlying mechanisms mediating transformation of chronic inflammation into fibrosis and to evaluate intervention protocols for treating conditions of fibrotic disorders.

    Human serum albumin (HSA) undergoes several structural alterations affecting its properties in pro-oxidant and pro-inflammatory environments, as it occurs during liver cirrhosis. These modifications include the formation of albumin dimers. Although HSA dimers were reported to be an oxidative stress biomarker, to date nothing is known about their role in liver cirrhosis and related complications. Additionally, no high sensitive analytical method was available for HSA dimers assessment in clinical settings. Thus the HSA dimeric form in human plasma was characterized by mass spectrometry using liquid chromatography tandem mass spectrometry (LC-ESI-Q-TOF) and matrix assisted laser desorption time of flight (MALDI-TOF) techniques. N-terminal and C-terminal truncated HSA, as well as the native HSA, undergo dimerization by binding another HSA molecule. This study demonstrated the presence of both homo- and hetero-dimeric forms of HSA. The dimerization site was proved to be at Cys-34, forming a disulphide bridge between two albumin molecules, as determined by LC-MS analysis after tryptic digestion. Interestingly, when plasma samples from cirrhotic subjects were analysed, the dimer/monomer ratio resulted significantly increased when compared to that of healthy subjects. These isoforms could represent promising biomarkers for liver disease. Additionally, this analytical approach leads to the relative quantification of the residual native HSA, with fully preserved structural integrity. Copyright © 2014 Elsevier B.V. All rights reserved.

  7. Role of oxidative stress in liver and kidney in uranium toxicity after chronic exposure

    2013-01-01

    Uranium is a radioactive heavy metal found in the environment. Due to its natural presence and to civil and militaries activities, general population can be exposed to U throughout drinking water or contaminated food. The pro/anti-oxidative system is a defense system which is often implicated in case of acute exposure to U. The aim of this thesis is to study the role of the pro/anti-oxidative system after chronic exposure to U in the liver and the kidney. After chronic exposure of rats to different U concentrations, this radionuclide accumulated in the organs in proportion to U intake; until 6 μg.g -1 of kidney tissues. U is localized in nucleus of the proximal tubular cells of the kidney. No nephrotoxicity was described even for the higher U level in drinking water and a reinforcement of the pro/anti-oxidative system with an increase in glutathione is observed. The study of U internal contamination in Nrf2 deficient mice, a cytoprotective transcription factor involved in the anti-oxidative defense has been realized. U accumulate more in Nrf2 mice than in WT mice but the biologic effects of U on the pro/anti-oxidative system did not seem to implicate Nrf2. At the cell level, a correlation between U distribution in HepG2 cells and the biological effects on this system is observed after U exposure at low concentrations. Soluble distribution of U is observed in cell nucleus. The apparition of U precipitates is correlated to the establishment of the adaptive mechanisms overtime which are overwhelmed and lead to a cellular toxicity at higher U level. In conclusion, these results suggest that the reinforcement of pro/anti-oxidative system could be an adaptive mechanism after chronic exposure at low U concentration. (author) [fr

  8. Renal Impairment with Sublethal Tubular Cell Injury in a Chronic Liver Disease Mouse Model.

    Directory of Open Access Journals (Sweden)

    Tokiko Ishida

    Full Text Available The pathogenesis of renal impairment in chronic liver diseases (CLDs has been primarily studied in the advanced stages of hepatic injury. Meanwhile, the pathology of renal impairment in the early phase of CLDs is poorly understood, and animal models to elucidate its mechanisms are needed. Thus, we investigated whether an existing mouse model of CLD induced by 3,5-diethoxycarbonyl-1,4-dihydrocollidine (DDC shows renal impairment in the early phase. Renal injury markers, renal histology (including immunohistochemistry for tubular injury markers and transmission electron microscopy, autophagy, and oxidative stress were studied longitudinally in DDC- and standard diet-fed BALB/c mice. Slight but significant renal dysfunction was evident in DDC-fed mice from the early phase. Meanwhile, histological examinations of the kidneys with routine light microscopy did not show definitive morphological findings, and electron microscopic analyses were required to detect limited injuries such as loss of brush border microvilli and mitochondrial deformities. Limited injuries have been recently designated as sublethal tubular cell injury. As humans with renal impairment, either with or without CLD, often show almost normal tubules, sublethal injury has been of particular interest. In this study, the injuries were associated with mitochondrial aberrations and oxidative stress, a possible mechanism for sublethal injury. Intriguingly, two defense mechanisms were associated with this injury that prevent it from progressing to apparent cell death: autophagy and single-cell extrusion with regeneration. Furthermore, the renal impairment of this model progressed to chronic kidney disease with interstitial fibrosis after long-term DDC feeding. These findings indicated that DDC induces renal impairment with sublethal tubular cell injury from the early phase, leading to chronic kidney disease. Importantly, this CLD mouse model could be useful for studying the

    Sex hormone receptors were quantitated in normal male rat liver and in regenerating liver at several different times after partial (70%) hepatectomy. Both estrogen and androgen receptor content were altered dramatically by partial hepatectomy. Total hepatic content and nuclear retention of estrogen receptors increased, with the zenith evident 2 days after partial hepatectomy, corresponding to the zenith of mitotic index. Serum estradiol increased after 1 day, and reached a maximum at 3 days after surgery. In contrast, total and nuclear androgen receptor content demonstrated a massive decline at 1, 2, and 3 days after resection. Serum testosterone displayed a parallel decline. In addition, hepatic content of two androgen-responsive proteins was reduced to 15% and 13% of normal values during this period. The activity of these various proteins during regeneration of male rat liver is comparable to that observed in the liver of normal female rats. Taken together, these results indicate that partial hepatectomy induces a feminization of certain sexually dimorphic aspects of liver function in male rats. Furthermore, these data provide evidence that estrogens, but not androgens, may have an important role in the process of liver regeneration. PMID:3758617

    [sup 99m]Tc-DTPA-HSA scintiangiography was performed in 81 cases of viral chronic liver disease, and a time-activity curve (TAC) of the liver was classified into three types (I, II, III). Furthermore, portal component of the total hepatic blood flow was calculated. The results were compared with those of [sup 99m]Tc-phytate scintigraphy. The TAC type changed from I through III according to the histological development of the liver. Esophageal varices was seen frequently in patients of type III, and in none of type I. The portal component significantly decreased in the order of chronic hepatitis without lobular distortion, with lobular distortion, and liver cirrhosis. However, the portal component obtained by using [sup 99m]Tc-phytate did not show a significant difference between chronic hepatitis without and with lobular distortion. [sup 99m]Tc-DTPA-HSA scintigraphy was thought to be a useful diagnostic procedure in patients with chronic liver disease. (author).

    Chronic liver disease (CLD) is a leading cause of death and is defined based on a specific set of underlying cause-of-death codes on death certificates. This conventional approach to measuring CLD mortality underestimates the true mortality burden because it does not consider certain CLD conditions like viral hepatitis and hepatocellular carcinoma. We measured how much the conventional CLD mortality case definition will underestimate CLD mortality and described the distribution of CLD etiologies in Connecticut. We used 2004 Connecticut death certificates to estimate CLD mortality two ways. One way used the conventional definition and the other used an expanded definition that included more conditions suggestive of CLD. We compared the number of deaths identified using this expanded definition with the number identified using the conventional definition. Medical records were reviewed to confirm CLD deaths. Connecticut had 29 314 registered deaths in 2004. Of these, 282 (1.0%) were CLD deaths identified by the conventional CLD definition while 616 (2.1%) were CLD deaths defined by the expanded definition. Medical record review confirmed that most deaths identified by the expanded definition were CLD-related (550/616); this suggested a 15.8 deaths/100 000 population mortality rate. Among deaths for which hepatitis B, hepatitis C and alcoholic liver disease were identified during medical record review, only 8.6%, 45.4% and 36.5%, respectively, had that specific cause-of-death code cited on the death certificate. An expanded CLD mortality case definition that incorporates multiple causes of death and additional CLD-related conditions will better estimate CLD mortality. Published 2014.

    Cuscuta seeds and whole plant have been used to nourish the liver and kidney. This study was aimed to investigate the hepatoprotective activity of the ethanol extract of Cuscuta campestris Yunck. whole plant (CC EtOH ). The hepatoprotective effect of CC EtOH (20, 100 and 500 mg/kg) was evaluated on carbon tetrachloride (CCl₄)-induced chronic liver injury. Serum alanine aminotransferase, aspartate aminotransferase, triglyceride and cholesterol were measured and the fibrosis was histologically examined. CC EtOH exhibited a significant inhibition of the increase of serum alanine aminotransferase, aspartate aminotransferase, triglyceride and cholesterol. Histological analyses showed that fibrosis of liver induced by CCl₄ were significantly reduced by CC EtOH . In addition, 20, 100 and 500 mg/kg of the extract decreased the level of malondialdehyde (MDA) and enhanced the activities of anti-oxidative enzymes including superoxide dismutase (SOD), glutathione peroxidase (GPx) and glutathione reductase (GRd) in the liver. We demonstrate that the hepatoprotective mechanisms of CC EtOH were likely to be associated to the decrease in MDA level by increasing the activities of antioxidant enzymes such as SOD, GPx and GRd. In addition, our findings provide evidence that C. campestris Yunck. whole plant possesses a hepatoprotective activity to ameliorate chronic liver injury.

    Full Text Available Angiogenesis is believed to be implicated in the pathogenesis of alcoholic liver disease (ALD. We aimed to explore the usefulness and accuracy of plasma angiogenic biomarkers for noninvasive evaluation of the severity of liver failure and ALD outcome. One hundred and forty-seven patients with ALD were prospectively enrolled and assessed based on their (1 gender, (2 age, (3 severity of liver dysfunction according to the Child-Turcotte-Pugh and MELD scores, and (4 the presence of ALD complications. Plasma levels of vascular endothelial growth factor (VEGF-A and angiopoietins 1 and 2 (Ang1 and Ang2 were investigated using ELISAs. Multivariable logistic regression was applied in order to select independent predictors of advanced liver dysfunction and the disease complications. Significantly higher concentrations of Ang2 and VEGF-A in ALD patients as compared to controls were found. There was no difference in Ang1 levels in both groups. A positive correlation of Ang2 levels with INR (Rho 0.66; P<0.0001 and its inverse correlation with plasma albumin levels (Rho –0.62; P<0.0001 were found. High Ang2 concentrations turned out to be an independent predictor of severe liver dysfunction, as well as hepatic encephalopathy and renal impairment. Ang2 possessed the highest diagnostic and prognostic potential among three studied angiogenesis-related molecules.

    Full Text Available Background: Hepatitis B virus infection in patients who lack detectable hepatitis B surface antigen (HBsAg is called occult hepatitis B infection (OHB. The very low level of HBV genome may hamper its detection by molecular techniques. Recently, a highly sensitive EIA utilizing a novel modified electron spin resonance (ESR technique (modified ESR-EIA was developed to detect HBsAg by measuring stabilized nitroxide radicals. Aim: to detect occult HBV infection, using ESR-EIA among HCV-related chronic liver disease (CLD Egyptian patients who were seronegative for HBsAg by standard EIA. Methods: The study was conducted on two periods of time; in 1st period, 72 inpatients in Tropical Medicine Department of TBRI, were enrolled in the study. They were divided into two groups; 44 seropositive anti-HCV patients (Group I, 28 seronegative anti-HCV patients (Group II. Sera were subjected to virological assays for HBsAg, HBeAg, anti-HBc IgM, anti-HBc IgG, anti-HBs, anti-HCV and HCV RNA. We also examined serum HBV DNA by polymerase chain reaction (PCR technique and real-time detection polymerase chain reaction (RTD-PCR. In the 2nd period; modified ESR-EIA was applied on 32 TBRI inpatients, 23 in Tropical Medicine Department (Group I and 9 from hemodialysis unit (Group II with HCV-related CLD. Results: OHB was detected in 18.1% and 86.9% of our patients in 2002 and 2006 respectively. In phase 1, there was a higher detection rate among HCV patients in Group I (25% than Group II (7%, with higher prevalence (52.4% in patients with positive HCV RNA in Group I versus those with negative HCV viremia (8% in Group II. HBV DNA by either PCR or RTD-PCR was negative in all patients of both groups as the HBV viral load of the samples were below detectable level of the methods used; less than 100 copies/ml. None of 9 hemodialysis patients were positive for OHB. Conclusion: The newly developed quantitative ESR-EIA technique represents a great evolution for screening and

    In chronic hepatitis C, the European Association for the Study of the Liver and the Asociacion Latinoamericana para el Estudio del Higado recommend performing transient elastography plus a blood test to diagnose significant fibrosis; test concordance confirms the diagnosis. To validate this rule and improve it by combining a blood test, FibroMeter (virus second generation, Echosens, Paris, France) and transient elastography (constitutive tests) into a single combined test, as suggested by the American Association for the Study of Liver Diseases and the Infectious Diseases Society of America. A total of 1199 patients were included in an exploratory set (HCV, n = 679) or in two validation sets (HCV ± HIV, HBV, n = 520). Accuracy was mainly evaluated by correct diagnosis rate for severe fibrosis (pathological Metavir F ≥ 3, primary outcome) by classical test scores or a fibrosis classification, reflecting Metavir staging, as a function of test concordance. Score accuracy: there were no significant differences between the blood test (75.7%), elastography (79.1%) and the combined test (79.4%) (P = 0.066); the score accuracy of each test was significantly (P tests. Classification accuracy: combined test accuracy (91.7%) was significantly (P blood test (84.1%) and elastography (88.2%); accuracy of each constitutive test was significantly (P tests but not with combined test: 89.0 vs. 92.7% (P = 0.118). Multivariate analysis for accuracy showed an interaction between concordance and fibrosis level: in the 1% of patients with full classification discordance and severe fibrosis, non-invasive tests were unreliable. The advantage of combined test classification was confirmed in the validation sets. The concordance recommendation is validated. A combined test, expressed in classification instead of score, improves this rule and validates the recommendation of a combined test, avoiding 99% of biopsies, and offering precise staging. © 2017 John Wiley & Sons Ltd.

    Full Text Available Background/AimsThe aim of this study was to identify the parameters that could noninvasively predict the presence of esophageal/gastric varices and portal hypertensive gastropathy (PHG in patients with chronic liver disease (CLD, and to determine the accuracy of those parameters.MethodsWe retrospectively analyzed 232 patients with CLD who underwent both upper endoscopy and liver CT within an interval of 3 months. The multidimensional index (M-Index for spleen volume was obtained from the multiplication of splenic length, width, and thickness, as measured by computer tomography.ResultsThe multivariate analysis revealed that platelet, albumin, and M-Index were independently associated with the presence of varices and PHG. We combined three independent parameters, and developed a varices and portal hypertensive gastropathy (VAP scoring system (=[platelet count (/mm3×albumin (g/dL]/[M-Index (cm3]. The area under the receiver operating characteristic curve of the VAP score was 0.850 (95% confidence interval, 0.801-0.899. The VAP cut-off value of 861 had a sensitivity of 85.3%, a positive likelihood ratio of 3.17, and a negative predictive value of 86.4%. For predicting high-risk lesions for bleeding, with a cut-off value of 861 the sensitivity was 92.0%, the positive likelihood ratio was 2.20, and the negative predictive value was 96.4%.ConclusionsThe VAP score can predict the presence of varices and PHG in patients with CLD and may increase the cost-benefit of screening endoscopy in the clinical practice setting. A prospective validation study is necessary in the future.

    Acute-on-chronic liver failure is associated with numerous consecutive organ failures and a high short-term mortality rate. Molecular adsorbent recirculating system therapy has demonstrated beneficial effects on the distinct symptoms, but the associated mortality data remain controversial. Retrospective analysis of acute-on-chronic liver failure patients receiving either standard medical treatment or standard medical treatment and molecular adsorbent recirculating system. Secondary analysis of data from the prospective randomized Recompensation of Exacerbated Liver Insufficiency with Hyperbilirubinemia and/or Encephalopathy and/or Renal Failure trial by applying the recently introduced Chronic Liver Failure-criteria. Medical Departments of University Hospital Muenster (Germany). This analysis was conducted in two parts. First, 101 patients with acute-on-chronic liver failure grades 1-3 and Chronic Liver Failure-C-Organ Failure liver subscore equals to 3 but stable pulmonary function were identified and received either standard medical treatment (standard medical treatment, n = 54) or standard medical treatment and molecular adsorbent recirculating system (n = 47) at the University Hospital Muenster. Second, the results of this retrospective analysis were tested against the Recompensation of Exacerbated Liver Insufficiency with Hyperbilirubinemia and/or Encephalopathy and/or Renal Failure trial. Standard medical treatment and molecular adsorbent recirculating system. Additionally to improved laboratory variables (bilirubin and creatinine), the short-term mortality (up to day 14) of the molecular adsorbent recirculating system group was significantly reduced compared with standard medical treatment. A reduced 14-day mortality rate was observed in the molecular adsorbent recirculating system group (9.5% vs 50.0% with standard medical treatment; p = 0.004), especially in patients with multiple organ failure (acute-on-chronic liver failure grade 2-3).

    The occurrence and distribution of fibronectin (FN) was assessed by an immunoperoxidase technique in liver biopsies from alcoholics without and with acinar zone 3 fibrosis of varying degrees. Increased amounts of FN was found diffusely in zone 3 areas with a perisinusoidal and pericellular...... localization. FN was closely correlating to the pattern of fibrosis but increased amounts of FN could also be seen in biopsies without fibrosis as visualized in Picro-Sirius stained sections. There was no topographical relationship to liver cells with fatty changes, Mallory bodies or to alcoholic hepatitis....... It is made probable that FN is of significance in the development of early liver fibrosis in alcoholics and that FN may act as a chemotactic factor for collagen producing cells and as a skeleton for the new collagen formation....

    Infection with hepatitis A and hepatitis B virus can increase the risk of morbidity and mortality in persons with chronic liver disease (CLD). The Advisory Committee on Immunization Practices recommends hepatitis A (HepA) and hepatitis B (HepB) vaccination for persons with CLD. Data from the 2014 and 2015 National Health Interview Surveys (NHIS), nationally representative, in-person interview surveys of the non-institutionalized US civilian population, were used to assess self-reported HepA (≥1 and ≥2 doses) and HepB vaccination (≥1 and ≥3 doses) coverage among adults who reported a chronic or long-term liver condition. Multivariable logistic regression was used to identify factors independently associated with HepA and HepB vaccination among adults with CLD. Overall, 19.4% and 11.5% of adults aged ≥ 18 years with CLD reported receiving ≥1 dose and ≥2 doses of HepA vaccine, respectively, compared with 14.7% and 9.1% of adults without CLD (p CLD, ≥1dose). Age, education, geographic region, and international travel were associated with receipt of ≥2 doses HepA vaccine among adults with CLD. Overall, 35.7% and 29.1% of adults with CLD reported receiving ≥1 dose and ≥3 doses of HepB vaccine, respectively, compared with 30.2% and 24.7% of adults without CLD (p CLD, ≥1 dose). Age, education, and receipt of influenza vaccination in the past 12 months were associated with receipt of ≥3 doses HepB vaccine among adults with CLD. Among adults with CLD and ≥10 provider visits, only 13.8% and 35.3% had received ≥2 doses HepA and ≥3 doses HepB vaccine, respectively. HepA and HepB vaccination among adults with CLD is suboptimal and missed opportunities to vaccinate occurred. Providers should adhere to recommendations to vaccinate persons with CLD to increase vaccination among this population. Copyright © 2018 Elsevier Ltd. All rights reserved.

    Pain-related worry is distinct from, but related to, pain catastrophizing (PC) and anxiety. Worry and its relationship with other variables have been studied in people with chronic pain but not in people with chronic orofacial pain. The authors explored the prevalence of trait, general and pain-related worry and the association of worry with higher pain levels and other variables. The authors assessed people who had a diagnosis of chronic orofacial pain by using nonpain-related trait worry, state anxiety, trait anxiety, PC and pain measures. The participants' answers to an open-ended question about what they were most worried about led to the identification of worry domains, including worry about pain. The authors found that worrying about pain was related significantly to worst and least pain levels, pain interference and pain duration, as well as moderated trait worry in predicting pain interference. Although trait worry was not correlated directly with pain, when moderated by PC, it made substantial contributions in predicting pain interference. Participants with chronic orofacial pain reported experiencing substantial levels of trait worry, anxiety, PC and worry about pain that related to pain ratings directly and indirectly. Clinicians should assess pain-related worry in patients with chronic orofacial pain to understand the effects of worry on pain and functioning. Clinicians could treat these patients more effectively by helping them reduce their levels of pain-related worry and focusing on improved coping.

    Full Text Available Abstract Objective Progressive immunodeficiency associated with HIV-infection leads to a progressive course of liver disease in HIV/HCV-co-infected patients. Highly active antiretroviral therapy (HAART efficiently restores and preserves immune functions and has recently been demonstrated to also result in reduced liver-related mortality in HIV/HCV-co-infected patients. Methods To analyse differences in current liver fibrosis as a possible effect of HAART on fibrosis progression we assessed hepatic fibrosis by transient elastography in a cross-sectional comparison between HCV-mono-infected and HIV/HCV-co-infected patients presenting at our outpatient department in 2007. Results Overall, we did not find any difference in the distribution of liver stiffness between mono- (n = 84 and double-infected (n = 57 patients (14.4 kPa (10.8 - 18.2 versus 12.4 kPa (9.1 - 16.1, mean (95%-CI. However, in the 8 HIV+ patients with CD4 counts Conclusions These findings are in line with other data that show an improved prognosis of chronic hepatitis C in HIV+ patients under effective HAART, and may be a hint that fibrosis progression in well-treated HIV+ patients will no longer be different from that in HCV-mono-infected patients.

    Results: The preoperative laboratory parameters showed statistically significant differences between the two groups regarding serum albumin, total bilirubin, ALT, AST, PT, PC and INR. The operative data showed statistically insignificant difference between the two groups regarding the 1st dose response (p = 0.152, the estimated ED80 (p = 0.886 and the calculated 2nd dose (p = 0.886 and statistically significant differences between the two groups regarding the 2nd dose response (p = 0.006, the measured ED50 (p = 0.010 and the measured ED95 (p = 0.001. In conclusion, the measured ED50 and ED95 through two-dose dose–response curve technique were clinically insignificant from using the single-dose technique. The dose–response curve of cisatracurium in patients with chronic liver disease was clinically insignificant in comparison with healthy subjects.

    Aims To characterize the pharmacokinetics (PK)/pharmacodynamics (PD) of eltrombopag in chronic liver disease (CLD). Methods The PK/PD model was developed using data from 79 CLD patients using nonlinear mixed-effects modelling. Results The PK of eltrombopag were described by a two-compartment model with dual sequential first-order absorption. Gender, race and severity of CLD were predictors of the apparent clearance of eltrombopag. The PD of eltrombopag in CLD were adequately described by a four-compartment lifespan model, in which eltrombopag stimulated platelet precursor production rate. East Asian CLD patients were less sensitive to the stimulatory effect of eltrombopag. Following a daily dose regimen of 50 mg eltrombopag, the time to achieve peak platelet counts was longer for the CLD population compared with patients who had immune thrombocytopenic purpura, but was comparable to patients with hepatitis C. Likewise, it took a longer time for platelet counts to rebound back to baseline once eltrombopag treatment was discontinued. Conclusions The time course of the platelet response in CLD was different from that in immune thrombocytopenic purpura but comparable to that in hepatitis C. PMID:24117976

    The role of serum biomarkers in the surveillance of hepatocellular carcinoma (HCC) is controversial. We assessed the diagnostic performances of alpha-fetoprotein (AFP) and protein-induced by vitamin-K-absence/antagonist-II (PIVKA-II) in 388 cirrhotic patients with chronic liver disease (CLD). Biomarkers were quantified by automated chemiluminescent-enzyme-immunoassays (Fujirebio, Tokyo, Japan) at HCC diagnosis in 258 patients (204 males; median age 66.9 years) and in 130 cirrhotics without HCC (104 males; median-age 60.6 years). CLD etiology in HCC/non-HCC was CHB in 48/35, CHC in 126/56 and Non-Viral in 84/39. Overall AUROC values for AFP and PIVKA-II were 0.698 (95%CI = 0.642-0.753, PCLD. AFP/PIVKA-II diagnostic accuracy was 40.5-59.8%/62.7-73.5% and combining both markers 78.2% for CHB, 77% for Non-Viral-CLD and 75% for CHC. AFP correlated with ALT in HCC patients with CHC (ρ= 0.463/PCLD (ρ= 0.359/P= 0.047), but not in CHB (treated with antivirals). PIVKA-II correlated with tumour size independently of CLD-etiology (PCLD; their combination provides a better diagnostic accuracy.

    The ratio of portal venous to hepatic blood flow was measured in chronic liver diseases by radionuclide angiography with 99m Tc-Sn colloid and its clinical value was discussed. The ratio was proportionally decreased to the progression of the diseases (normal 74.5±7.3%, chronic hepatitis 58.8±9.2%, compensated liver cirrhosis 49.0±10.4%, and decokmpensated liver cirrhosis 29.3±19.3%). In alcoholic liver diseases, the standard deviation of the ratio was large as 52.7±23.7%, and the low ratio in the early period of the disease increased within one or two months as the disease recovered. In comparison with the histological findings of the liver, the ratio in the alcoholic liver diseases was well correlated with the severity of liver fibrosis and liver cell swelling. In conclusion, this noninvasive and simple method is valuable in diagnosing the chronic liver disease, especially alcoholic liver diseases, and also in estimating its clinical course. (author)

    The effects of somatostatin (growth hormone release inhibiting hormone) on basal gastrin were studied in patients suffering from pernicious anaemia and chronic renal and liver disease, and during sequential arginine/insulin-stimulated gastrin release in normal subjects. When basal gastrin concentrations were normal (10-50 pg/ml) in controls and in patients who were in renal and liver failure, somatostatin had no effect on gastrin levels. Raised basal gastrin levels in pernicious anaemia and in 2 cases of chronic renal disease, were significantly inhibited by somatostatin with a half-life (T-half) of 3 to 4 minutes. Arginine infusion caused an insignificant rise in serum gastrin which was unaffected by somatostatin, whereas insulin hypoglycaemia significantly stimulated gastrin release, which was inhibited by somatostatin.

    Full Text Available The aim of this research was to develop a method for noninvasive staging of liver fibrosis (LF in patients with chronic hepatitis C (CHC based on ultrasound imaging (UI of the abdominal cavity. We examined 124 patients with CHC. The diagnosis was verified on the basis of clinical and epidemiological, serological and molecular biological data. Direct ultrasonic parameters of the structure and hemodynamics of liver and spleen were supplemented with estimated indicators: square of the expected cross-section of the lobes of the liver and spleen, as well as their ratio. On the basis of the discriminant analysis of the survey data of 82 patients, we developed an analytical model (with predictive value of 95.2% for interval estimation of the fibrosis degree in CHC patients. We have concluded that UI performed on modern equipment, including Doppler, is able to determine the degree of LF without resorting to histological verification.

    Portal hypertension is a common complication of chronic liver diseases associated with liver fibrosis and cirrhosis. At present, beta-blockers such as carvedilol remain the medical treatment of choice for protection against variceal bleeding and other complications. Since carvedilol has powerful antioxidant properties we assessed the potential antifibrotic effects of carvedilol and the underlying mechanisms that may add further benefits for its clinical usefulness using a chronic model of carbon tetrachloride (CCl4)-induced hepatotoxicity. Two weeks after CCl4 induction of chronic hepatotoxicity, rats were co-treated with carvedilol (10 mg/kg, orally) daily for 6 weeks. It was found that treatment of animals with carvedilol significantly counteracted the changes in liver function and histopathological lesions induced by CCl4. Also, carvedilol significantly counteracted lipid peroxidation, GSH depletion, and reduction in antioxidant enzyme activities; glutathione-S-transferase and catalase that was induced by CCl4. In addition, carvedilol ameliorated the inflammation induced by CCl4 as indicated by reducing the serum level of acute phase protein marker; alpha-2-macroglobulin and the liver expression of nuclear factor-kappa B (NF-κB). Finally, carvedilol significantly reduced liver fibrosis markers including hydroxyproline, collagen accumulation, and the expression of the hepatic stellate cell (HSC) activation marker; alpha smooth muscle actin. In conclusion, the present study provides evidences for the promising antifibrotic effects of carvedilol that can be explained by amelioration of oxidative stress through mainly, replenishment of GSH, restoration of antioxidant enzyme activities and reduction of lipid peroxides as well as amelioration of inflammation and fibrosis by decreasing collagen accumulation, acute phase protein level, NF-κB expression and finally HSC activation. -- Highlights: ► Carvedilol is a beta blocker with antioxidant and antifibrotic

    Glucocorticoids have been implicated in nonalcoholic fatty liver diseases (NAFLD). The influence of a palatable diet on the response to stress is controversial. This study explored whether a high-sucrose diet could protect from hepatic steatosis induced by chronic restraint stress in young adult rats. Male Wistar rats aged 21 days were allocated into four groups (n = 6-8 per group): control, chronic restraint stress, 30% sucrose diet, and 30% sucrose diet plus chronic restraint stress. After being exposed to either tap water or sucrose solution during eight weeks, half of the rats belonging to each group were subject or not to repeated restraint stress (1 h per day, 5 days per week) during four weeks. Triacylglycerol (TAG), oxidative stress, activity of 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD-1), infiltration of immune cells, and glycogen amount in the liver were quantified. Serum concentrations of corticosterone and testosterone were also measured. The stressed group showed normal serum concentrations of corticosterone and did not have hepatic steatosis. However, this group showed increased glycogen, inflammation, mild fibrosis, oxidative stress, and a high activity of 11β-HSD-1 in the liver. The group exposed to the high-sucrose diet had lower concentrations of corticosterone, hepatic steatosis and moderate fibrosis. The group subject to high-sucrose diet plus chronic restraint stress showed low concentrations of corticosterone, hepatic steatosis, oxidative stress, and high concentrations of testosterone. Thus, restraint stress and a high-sucrose diet each generate different components of nonalcoholic fatty liver in young adult rats. The combination of both the factors could promote a faster development of NAFLD.

    Current chronic liver disease (CLD) mortality surveillance methods may not adequately capture data on all causes of CLD mortality. The objective of this study was to calculate and compare CLD death rates in New Mexico and the United States by using both an expanded definition of CLD and estimates of the fractional impact of alcohol on CLD deaths. We defined CLD mortality as deaths due to alcoholic liver disease, cirrhosis, viral hepatitis, and other liver conditions. We estimated alcohol-attributable CLD deaths by using national and state alcohol-attributable fractions from the Centers for Disease Control and Prevention's Alcohol-Related Disease Impact application. We classified causes of CLD death as being alcohol-attributable, non-alcohol-attributable, or hepatitis C. We calculated average annual age-adjusted CLD death rates during five 3-year periods from 1999 through 2013, and we stratified those rates by sex, age, and race/ethnicity. By cause of death, CLD death rates were highest for alcohol-attributable CLD. By sex and race/ethnicity, CLD death rates per 100 000 population increased from 1999-2001 to 2011-2013 among American Indian men in New Mexico (67.4-90.6) and the United States (38.9-49.4), American Indian women in New Mexico (48.4-63.0) and the United States (27.5-39.5), Hispanic men in New Mexico (48.6-52.0), Hispanic women in New Mexico (16.9-24.0) and the United States (12.8-13.1), non-Hispanic white men in New Mexico (17.4-21.3) and the United States (15.9-18.4), and non-Hispanic white women in New Mexico (9.7-11.6) and the United States (7.6-9.7). CLD death rates decreased among Hispanic men in the United States (30.5-27.4). An expanded CLD definition and alcohol-attributable fractions can be used to create comprehensive data on CLD mortality. When stratified by CLD cause and demographic characteristics, these data may help states and jurisdictions improve CLD prevention programs.

    To compare the effectiveness of portal vein embolization (PVE) performed using gelfoam or a gelfoam-coil combination before major hepatic resection in patients with chronic liver disease. PVE using gelfoam or a gelfoam-coil combination was performed in 37 patients. From April 2003 to September 2007, PVE was performed using gelfoam (n = 17) and a gelfoam-coil combination (n = 20) to induce hypertrophy. Computed tomography volumetry was performed 2-4 weeks after PVE to assess the changes in liver volume. The mean percentage increase in future liver remnant volume was 23.7 +/- 23.7% in the gelfoam group and 36.7 +/- 18.5% in the gelfoam-coil group (p = 0.02). Recanalization was found in 15 gelfoam group patients and 8 gelfoam-coil group patients (p = 0.003). The mean tumor size increased from 4.5 +/- 2.9 cm before PVE to 5.0 +/- 3.5 cm after PVE in the gelfoam group and from 4.3 +/- 2.2 cm before PVE to 4.7 +/- 2.5 cm after PVE in the gelfoam-coil group (p = 0.80). The gelfoam-coil combination was more effective than gelfoam alone for induction of compensatory hypertrophy by PVE in patients with chronic liver disease.

    In order to evaluate the changes in biochemical liver function tests and hepatic scintigraphic findings of chronic hepatitis, the author analyzed 35 patients who underwent serial liver biopsies. The results were summerized as follows: 1. Histological deteriorations in chronic hepatitis more inclined to be presented in the scintigraphic abnormalities such as the increased uptake of radioisotope in the spleen and bone marrow than the deteriorations in biochemical liver function tests. Moreover, the increased radioisotope uptake by spleen and bone marrow in hepatic scintigram highly correlated with histological deteriorations. On the other hand, in the cases with histological improvement no scintigraphic improvement was ovserved. 2. Comparing the changes in the result of liver function tests with histological features, biochemical deteriorations significantly correlated with histological deteriorations, although biochemical improvements were not reliable indicators of histological improvements. 3. Changes in biochemical parameters such as serum GOT, GPT, albumin, γ-globulin, TTT and ALP were analyzed by means of Hayashi's second method of quantification and predictive values for histological feactures were calculated. As a result, histological deteriorations were predicted in 89.5% of the cases, but histological improvements were predicted only in 66.7%. In the various biochemical parameters, γ-globulin was considered as most important in predicting histological features and ALP was ranked the second. (J.P.N.)

    Detection of subclinical hepatic encephalopathy in children is difficult. We aimed to assess the changes in imaging of the central nervous system in children with chronic liver disease using MR imaging, diffusion, and {sup 1}H -spectroscopy. Forty three children with chronic liver disease and/or porto-systemic shunting (111.4±56.9 months) and 24 controls (72.0±51.8 months) underwent brain MRI/spectroscopy on a 1.5T to examine T1, T2, ADC, Cho/Cr, ml/Cr, Glx/Cr ratio spectroscopy in the globus pallidus. Patients were divided into 3 groups according to the ratios of globus pallidus/putamen T1 signal: isointense (i), hyperintense (h), much more hyperintense (h+). The relationship with clinical and biological data was analyzed. T1 signal intensity and ml/Cr were significantly different between controls and group h+ (p=0.001). ADC did not differ significantly between groups. Age correlated strongly with the presence of a T1 signal ratio (p > 0.001). There was no correlation between imaging findings and biological parameters. In children with chronic liver disease and/or porto-systemic shunting, the presence of a hyperintense T1 signal in the globus pallidus correlated strongly with age. Biological and clinical parameters were not predictive of these changes. MRI may become a useful screening tool for hepatic encephalopathy in children. (orig.)

    Controversial results have been reported about the effects of alcoholism on the functionality of monocytes. In the present study we analyze the effects of chronic alcoholism on the intracellular production of inflammatory cytokines by peripheral blood (PB) monocytes. Spontaneous and in vitro-stimulated production of interleukin (IL) 1alpha (TNFalpha) by PB monocytes was analyzed at the single level by flow cytometry in chronic alcoholics without liver disease and active ethanol (EtOH) intake (AWLD group), as well as in patients with alcohol liver cirrhosis (ALC group), who were either actively drinking (ALCET group) or with alcohol withdrawal (ALCAW group). A significantly increased spontaneous production of IL1beta, IL6, IL12, and TNFalpha was observed on PB monocytes among AWLD individuals. Conversely, circulating monocytes form ALCET patients showed an abnormally low spontaneous and stimulated production of inflammatory cytokines. No significant changes were observed in ALCAW group as regards production of IL1beta, IL6, IL12, and TNFalpha. Our results show an altered pattern of production of inflammatory cytokines in PB monocytes from chronic alcoholic patients, the exact abnormalities observed depending on both the status of EtOH intake and the existence of alcoholic liver disease.

    2007-01-01

    Chronic liver disease is one of the major complications of cystic fibrosis (CF). Significant liver disease is seen in 13-25% of children with CF. Improved life expectancy and prolonged follow-up have favored better characterization of the hepatic manifestations of CF and allowed direct observation of an increasing number of liver-related events. Liver disease typically develops in the first decade of life, with the incidence dropping rapidly after the age of 10 years. The wide spectrum of liver disease ranging from asymptomatic gallbladder abnormalities to biliary cirrhosis will be reviewed in this article

    Despite the central role of proteasomes in relevant physiological pathways and pathological processes, this topic is unexpectedly largely unexplored in human liver. Here we present data on the presence of proteasome and immunoproteasome in human livers from normal adults, fetuses and patients affected by major hepatic diseases such as cirrhosis and chronic active hepatitis. Immunohistochemistry for constitutive (α4 and β1) and inducible (LMP2 and LMP7) proteasome subunits, and for the PA28αβ regulator, was performed in liver samples from 38 normal subjects, 6 fetuses, 2 pediatric cases, and 19 pathological cases (10 chronic active hepatitis and 9 cirrhosis). The immunohistochemical data have been validated and quantified by Western blotting analysis. The most striking result we found was the concomitant presence in hepatocyte cytoplasm of all healthy subjects, including the pediatric cases, of constitutive proteasome and immunoproteasome subunits, as well as PA28αβ. At variance, immunoproteasome was not present in hepatocytes from fetuses, while a strong cytoplasmic and nuclear positivity for LMP2 and LMP7 was found in pathological samples, directly correlated to the histopathological grade of inflammation. At variance from other organs such as the brain, immunoproteasome is present in livers from normal adult and pediatric cases, in apparent absence of pathological processes, suggesting the presence of a peculiar regulation of the proteasome/immunoproteasome system, likely related to the physiological stimuli derived from the gut microbiota after birth. Other inflammatory stimuli contribute in inducing high levels of immunoproteasome in pathological conditions, where its role deserve further attention.

    Despite the possible role of adiponectin in the pathogenesis of liver cirrhosis, few data have been collected from patients in different stages of liver fibrosis. We studied the role of adiponectin in 2 chronic hepatitis B (CHB)-patient cohorts. Serum adiponectin was quantified by enzyme-linked immunosorbent assay. One-hundred liver biopsy specimens from CHB patients with different stages of fibrosis and 38 paired liver biopsies from hepatitis B e antigen-positive patients randomized to lamivudine (n=15), pegylated interferon alfa-2a (n=15) or pegylated interferon alfa-2a plus lamivudine (n=8) therapy for 48 weeks were assessed. Serum adiponectin was detected at levels ranging over fourfold magnitude with advancing fibrosis stage and correlated positively with fibrosis stage [r=0.45, p<0.001]. CHB patients with stage 0-1 fibrosis had higher composition of high molecular weight (HMW) form of adiponectin when compared with CHB patients with liver cirrhosis [mean+/-SEM 51.2+/-2.1% vs. 40.9+/-1.7%, respectively, p=0.001]. After antiviral therapy, patients with fibrosis reduction had marked decline in serum adiponectin level and increase in HMW form of adiponectin [mean+/-SEM 43.5+/-1.2% vs. 37.0+/-3.0%, respectively, p=0.04]. Serum adiponectin may have a role in fibrosis progression in CHB infection. A marked decline in serum adiponectin after antiviral therapy is associated with fibrosis reduction.

    To identify predictors for the discrimination of intrahepatic cholangiocarcinoma (IMCC) and combined hepatocellular-cholangiocarcinoma (CHC) from hepatocellular carcinoma (HCC) for primary liver cancers on gadoxetic acid-enhanced MRI among high-risk chronic liver disease (CLD) patients using classification tree analysis (CTA). A total of 152 patients with histopathologically proven IMCC (n = 40), CHC (n = 24) and HCC (n = 91) were enrolled. Tumour marker and MRI variables including morphologic features, signal intensity, and enhancement pattern were used to identify tumours suspicious for IMCC and CHC using CTA. On CTA, arterial rim enhancement (ARE) was the initial splitting predictor for assessing the probability of tumours being IMCC or CHC. Of 43 tumours that were classified in a subgroup on CTA based on the presence of ARE, non-intralesional fat, and non-globular shape, 41 (95.3 %) were IMCCs (n = 29) or CHCs (n = 12). All 24 tumours showing fat on MRI were HCCs. The CTA model demonstrated sensitivity of 84.4 %, specificity of 97.8 %, and accuracy of 92.3 % for discriminating IMCCs and CHCs from HCCs. We established a simple CTA model for classifying a high-risk group of CLD patients with IMCC and CHC. This model may be useful for guiding diagnosis for primary liver cancers in patients with CLD.

    Full Text Available Background: The aim of this study is to investigate the association between hepatic activity index (HAI and fibrosis score (FS with inflammation biomarkers in non-uremic and uremic hepatitis C positive patients. Methods: Fifty chronic hepatitis C (cHepC positive patients, having a liver biopsy were included in this study. Liver biopsies were scored according to modified ISHAC scoring system. 25 healthy controls of similar age and gender were also enrolled as control group. Serum YKL-40, neutrophil/lymphocyte ratio (NLR, thrombocyte/lymphocyte ratio (PLR, CRP and Immunoglobulin (IgG, A and M levels were used to determine inflammation. AST to Platelet Ratio Index (APRI score was also evaluated. According to biopsy findings patients were divided into 2 groups: low (0–2 and severe (3–6 FS. Results: Patients with cHepC had increased inflammation compared to the healthy controls. End-stage renal disease (ESRD patients had higher levels of inflammation markers (NLR, IgG, CRP and YKL-40 and lower HCV RNA levels, HAI and FS compared to non-uremic patients. When patients were grouped into 2 according to FS as mild and severe, IgG (p < 0.001, YKL-40 (p = 0.02 levels and APRI score (p = 0.002 were significantly higher compared to mild FS (p = 0.002. YKL-40 levels (t value: 3.48; p = 0.001 and APRI score (t value: 4.57, p < 0.001 were found as independent associated with FS in non-uremic patients. However, in adjusted models, only APRI score (t value: 3.98, p = 0.002 was an independent associated with FS in ESRD patients. Conclusion: In non-uremic cHepC patients, YKL-40 levels and APRI score may be valuable markers of FS. In ESRD patients, there is not sufficient data for prediction of HAI and FS. In these patients, APRI score may provide better information.

    Full Text Available Aim. To investigate the effects of acute and chronic exercise on glucose and lipid metabolism in liver of rats with type 2 diabetes caused by a high fat diet and low dose streptozotocin (STZ. Methods. Animals were classified into control (CON, diabetes (DC, diabetic chronic exercise (DCE, and diabetic acute exercise (DAE groups. Results. Compared to CON, the leptin levels in serum and liver and ACC phosphorylation were significantly higher in DC, but the levels of liver leptin receptor, AMPKα1/2, AMPKα1, and ACC proteins expression and phosphorylation were significantly lower in DC. In addition, the levels of liver glycogen reduced significantly, and the levels of TG and FFA increased significantly in DC compared to CON. Compared to DC, the levels of liver AMPKα1/2, AMPKα2, AMPKα1, and ACC phosphorylation significantly increased in DCE and DAE. However, significant increase of the level of liver leptin receptor and glycogen as well as significant decrease of the level of TG and FFA were observed only in DEC. Conclusion. Our study demonstrated that both acute and chronic exercise indirectly activated the leptin-AMPK-ACC signaling pathway and increased insulin sensitivity in the liver of type 2 diabetic rats. However, only chronic and long-term exercise improved glucose and lipid metabolism of the liver.

    The development of acute-on-chronic liver failure (ACLF) in patients with liver cirrhosis is associated with high mortality rates. Renal failure is the most significant organ dysfunction that occurs in ACLF. So far there are no biomarkers predicting ACLF. We investigated whether cystatin C (CysC) and neutrophil gelatinase-associated lipocalin (NGAL) can predict development of renal dysfunction (RD), hepatorenal syndrome (HRS), ACLF, and mortality. We determined the plasma levels of CysC and NGAL in 429 patients hospitalized for acute decompensation of cirrhosis in the EASL-CLIF Acute-on-Chronic Liver Failure in Cirrhosis (CANONIC) study. The patients were followed for 90 days. Patients without RD or ACLF at inclusion but with development of either had significantly higher baseline concentrations of CysC and NGAL compared to patients without. CysC, but not NGAL, was found to be predictive of RD (odds ratio, 9.4; 95% confidence interval [CI], 1.8-49.7), HRS (odds ratio, 4.2; 95% CI, 1.2-14.8), and ACLF (odds ratio, 5.9; 95% CI, 1.3-25.9). CysC at day 3 was not found to be a better predictor than baseline CysC. CysC and NGAL were both predictive of 90-day mortality, with hazard ratios for CysC of 3.1 (95% CI, 2.1-4.7) and for NGAL of 1.9 (95% CI, 1.5-2.4). Baseline CysC is a biomarker of RD, HRS, and ACLF and an independent predictor of mortality in patients with acutely decompensated liver cirrhosis, though determining CysC at day 3 did not provide any benefit; while NGAL is also associated with short-term mortality, it fails to predict development of RD, HRS, and ACLF. Baseline CysC may help to identify patients at risk earlier and improve clinical management. (Hepatology 2017;66:1232-1241). © 2017 by the American Association for the Study of Liver Diseases.

    Accurate clinical assessment of liver fibrosis is essential and the aim of our study was to compare and combine hemodynamic Doppler ultrasonography, liver stiffness by transient elastography, and non-invasive serum biomarkers with the degree of fibrosis confirmed by liver biopsy, and thereby to determine the value of combining non-invasive method in the prediction significant liver fibrosis. We included 102 patients with chronic liver disease of various etiology. Each patient was evaluated using Doppler ultrasonography measurements of the velocity and flow pattern at portal trunk, hepatic and splenic artery, serum fibrosis biomarkers, and transient elastography. These parameters were then input into a multilayer perceptron artificial neural network with two hidden layers, and used to create models for predicting significant fibrosis. According to METAVIR score, clinically significant fibrosis (≥F2) was detected in 57.8% of patients. A model based only on Doppler parameters (hepatic artery diameter, hepatic artery systolic and diastolic velocity, splenic artery systolic velocity and splenic artery Resistance Index), predicted significant liver fibrosis with a sensitivity and specificity of75.0% and 60.0%. The addition of unrelated non-invasive tests improved the diagnostic accuracy of Doppler examination. The best model for prediction of significant fibrosis was obtained by combining Doppler parameters, non-invasive markers (APRI, ASPRI, and FIB-4) and transient elastography, with a sensitivity and specificity of 88.9% and 100%. Doppler parameters alone predict the presence of ≥F2 fibrosis with fair accuracy. Better prediction rates are achieved by combining Doppler variables with non-invasive markers and liver stiffness by transient elastography.

    Liver metastasis is the main cause of death from colorectal cancer. Alcohol consumption impacts liver function and is suggested to be an independent risk factor for liver metastasis of colorectal cancer, but no experimental evidence supporting this hypothesis has been demonstrated to date. In this study, we investigated the effect of alcohol intake on liver metastasis. We examined colon cancer cell spread from the spleen in mice provided with water (control group), alcohol for 4 weeks before tumor injection (prealcohol), alcohol for 3 weeks after tumor injection (postalcohol), or alcohol throughout the 7-week study (alcohol). Alcohol intake significantly increased hepatic metastatic burden in the prealcohol (2.4-fold, P < 0.001), postalcohol (2.0-fold, P < 0.01), and alcohol groups (2.2-fold, P < 0.001). A fluorescence-based metastasis tracking assay also confirmed an alcohol-induced increase in the abundance of tumor cells in the liver (2.5-fold, P < 0.001). Investigation of the host microenvironment revealed an alcohol-induced inflammatory response marked by elevated TNFα, IL1β, IL6, and IFNγ protein levels, as well as increased expression of intercellular molecule-1 (ICAM1) in hepatic tissues after 4 weeks of alcohol consumption. Moreover, the peripheral blood of mice provided with alcohol for 4 weeks exhibited reduced natural killer and CD8(+) T-cell counts. Collectively, our findings suggest that chronic alcohol consumption accelerates liver metastasis of colorectal cancer cells through alterations to the liver microenvironment and inactivation of immune surveillance.

    Twenty years after Chernobyl accident, the daily ingestion of foodstuff grown on contaminated grounds remains the main source for internal exposure to ionizing radiations, and primarily to cesium 137 ((137)Cs). Though the effects of a long-term internal contamination with radionuclides are poorly documented, several non-cancerous pathologies have been described in this population. However, lipid metabolism was never investigated after chronic internal contamination although disturbances were observed in externally-exposed people. In this regard, we assessed the effects of a chronic ingestion of (137)Cs on hepatic and cerebral cholesterol metabolism. To mimic a chronically-exposed population, rats were given (137)Cs-supplemented water at a post-accidental dose (150 Bq/rat/day) during 9 months. The plasma profile, and brain and liver cholesterol concentrations were unchanged. A decrease of ACAT 2, Apo E, and LXRmRNA levels was recorded in the liver. In the brain, a decrease of CYP27A1 and ACAT 1 gene expression was observed. These results clearly show that cholesterol metabolism is not disrupted by a chronic ingestion of (137)Cs, although several molecular alterations are observed. This work would be interestingly completed by studying the influence of (137)Cs in models likely more sensitive to contaminants, such as the fetus or individuals susceptible to a lipidic disease.

    Highlights: • Zn and Cd induced some differences in oxidative damage in the liver of zebrafish. • Zn and Cd enhanced expression of Cu/Zn-SOD and CAT through Nrf2 pathway. • Zn and Cd did not affected protein levels of CAT. • Cd inhibited biological activities of Cu/Zn-SOD and CAT proteins. • Zn stimulated activity and protein levels of Cu/Zn-SOD. - Abstract: Based on the same toxic level of 0.6% LC_5_0 for 96-h and the severe situation of water pollution, we compared effects of chronic Zn (180 μg L"−"1) and Cd exposures (30 μg L"−"1) on growth, survival, histology, ultrastructure, and oxidative stress in the liver of zebrafish for 5 weeks. Growth performance and survival rate remained relatively constant under Zn stress, but was reduced under Cd exposure. Cd exposure also induced severe pyknotic nuclei, evident ultrastructure damage, and considerable lipid inclusions in the hepatocytes. However, these phenomena were not pronounced under Zn exposure. The negative effects caused by Cd may be explained by an increase in hepatic oxidative damage, as reflected by the enhanced levels of lipid peroxidation (LPO) and protein carbonylation (PC). The reduced activity of Cu/Zn-superoxide dismutase (Cu/Zn-SOD) and catalase (CAT) may result in the enhanced hepatic oxidative damage, though the mRNA and protein levels of both genes increased and remained unchanged respectively. On the contrary, Zn up-regulated the levels of mRNA, protein and activity of Cu/Zn-SOD, which may contribute to the decreased LPO levels. Nonetheless, the sharply up-regulated mRNA levels of CAT did not induce an increase in the protein and activity levels of CAT under Zn stress. Furthermore, transcription factor NF-E2-related factor 2 (Nrf2) expression parelleled with its target genes, suggesting that Nrf2 is required for the protracted induction of antioxidant genes. In conclusion, our data demonstrated that essential and non-essential metals induced some differences in oxidative damage

    Anemia is a major consequence of chronic kidney disease (CKD) that develops early in the course of illness and affects most patients who exhibit some degree of reduced renal function. Erythropoietin (EPO) deficiency is considered the most important cause of anemia in CKD. Renal anemia has serious clinical consequence. In addition to reducing patient physical capacity and quality of life, anemia induces adaptive cardiovascular mechanisms that increase the risk of cardiovascular disease and death. Thus, treatment of anemia in CKD is very important. While EPO is effective in correcting anemia in most cases, up to 10% of patients however, have an inadequate response to therapy. The two most common and important reasons why patients become relatively unresponsive to EPO therapy are the development of true iron deficiency and the onset of an inflammatory state that impairs the response to EPO. Indeed, the role of inflammation and pro-inflammatory cytokines in resistance to EPO therapy is gaining increasing recognition. On the other hand, the main organ for C-reactive protein (CRP) synthesis is the liver and it is well known that the synthesis of an acute-phase proteins by the liver is up regulated by inflammation. The main consequence of nonalcoholic fatty liver disease (NAFLD) is sub-chronic liver inflammation that leads and contributes to dyslipidemia, inflammation, enhanced oxidative stress and endothelial dysfunction. Considering the recent data about high prevalence of NAFLD in CKD patients, probably due to shared metabolic risk factors, we hypothesized that end-stage renal disease (ESRD) patients with NAFLD will need a much higher dose of EPO to achieve the target hemoglobin levels in comparison with ESRD patients without NAFLD. The possible underlying mechanism is sub-chronic liver inflammation in NAFLD patients that leads and contributes to poor response to EPO. Therefore, we believe that NAFLD could be a new clinical marker of poor response to EPO therapy in

    Hypertension is accompanied by perturbations to the endocannabinoid and antioxidant systems. Thus, potential pharmacological treatments for hypertension should be examined as modulators of these two metabolic systems. The aim of this study was to evaluate the effects of chronic administration of the fatty acid amide hydrolase (FAAH) inhibitor [3-(3-carbamoylphenyl)phenyl]N-cyclohexylcarbamate (URB597) on the endocannabinoid system and on the redox balance in the livers of DOCA-salt hypertensive rats. Hypertension caused an increase in the levels of endocannabinoids [anandamide (AEA), 2-arachidonoyl-glycerol (2-AG) and N-arachidonoyl-dopamine (NADA)] and CB{sub 1} receptor and the activities of FAAH and monoacylglycerol lipase (MAGL). These effects were accompanied by an increase in the level of reactive oxygen species (ROS), a decrease in antioxidant activity/level, enhanced expression of transcription factor Nrf2 and changes to Nrf2 activators and inhibitors. Moreover, significant increases in lipid, DNA and protein oxidative modifications, which led to enhanced levels of proapoptotic caspases, were also observed. URB597 administration to the hypertensive rats resulted in additional increases in the levels of AEA, NADA and the CB{sub 1} receptor, as well as decreases in vitamin E and C levels, glutathione peroxidase and glutathione reductase activities and Nrf2 expression. Thus, after URB597 administration, oxidative modifications of cellular components were increased, while the inflammatory response was reduced. This study revealed that chronic treatment of hypertensive rats with URB597 disrupts the endocannabinoid system, which causes an imbalance in redox status. This imbalance increases the levels of electrophilic lipid peroxidation products, which later participate in metabolic disturbances in liver homeostasis. - Highlights: • Chronic administration of URB597 to hypertensive rats reduces liver inflammation. • URB597 enhances the redox imbalance in the

    Full Text Available Background: Etiology of nearly 30% cases of chronic viral hepatitis remains undetected. Occult HBV infection (OBI has emerged as an important clinical entity in this scenario. Apart from prevalence and clinical outcome of OBI patients genotype was determined in northern region of India. Materials and Methods: A total of 847 patients with chronic liver disease (CLD were screened for common viral etiologies and others serological markers of HBV. Amplification of surface, precore and polymerase genes of HBV was performed in patients negative for other etiologies. Genotyping and sequencing of the precore region was performed for OBI cases. Results: Twenty-nine (7.61% cases of OBI were identifiedof which 9 had chronic liver disease (CHD, 11 liver cirrhosis (LC and 9 hepatocellular carcinoma (HCC. Majority of OBI cases were detected by amplification of surface gene 26 (89.6%, followed by pre-core gene 12 (41.3%. Their liver functions tests were significantly deranged in comparison to overt HBV cases. IgG anti HBc was present in 8 (27.6% OBI cases. Mutation was observed in 8 (32% in pre-core region at nt. 1896 of overt HBV cases. Genotype D was the predominant genotype. In conclusion: OBI in our study was characterized by predominance of genotype D and more severe clinical and biochemical profile in comparison to overt HBV. IgG anti HBc positivity could be utilized as a marker of OBI. We recommend use of sensitive nested PCR for diagnosis of OBI, amplifying at least surface and precore gene.

    Full Text Available ObjectiveTo learn the clinical characteristics of concurrent acute-on-chronic liver failure (ACLF and hepatorenal syndrome (HRS, and to investigate the predictive factors for HRS in patients with ACLF. MethodsA total of 806 patients with ACLF who were admitted to our hospital from January 2012 to May 2014 were selected and divided into two groups according to the incidence of concurrent HRS. Clinical indices and laboratory test results were analyzed in the two groups, and the multivariate logistic regression analysis was used to figure out independent indices for the prediction of HRS in patients with ACLF. A prediction model was established and the receiver operating characteristic curve was drawn to evaluate the accuracy of the prediction model. Comparison of continuous data between the two groups was made by t test, and comparison of categorical data between the two groups was made by χ2 test. ResultsIn all patients with ACLF, 229 had HRS and 577 had no HRS. The univariate logistic regression analysis showed that hepatic encephalopathy, peritonitis, i
