    Acute kidney injury (AKI),defined as an abrupt increase in the serum creatinine level by at least 0.3 mg/dL,occurs in about 20% of patients hospitalized for decompensating liver cirrhosis.Patients with cirrhosis are susceptible to developing AKI because of the progressive vasodilatory state,reduced effective blood volume and stimulation of vasoconstrictor hormones.The most common causes of AKI in cirrhosis are pre-renal azotemia,hepatorenal syndrome and acute tubular necrosis.Differential diagnosis is based on analysis of circumstances of AKI development,natriuresis,urine osmolality,response to withdrawal of diuretics and volume repletion,and rarely on renal biopsy.Chronic glomeruIonephritis and obstructive uropathy are rare causes of azotemia in cirrhotic patients.AKI is one of the last events in the natural history of chronic liver disease,therefore,such patients should have an expedited referral for liver transplantation.Hepatorenal syndrome (HRS) is initiated by progressive portal hypertension,and may be prematurely triggered by bacterial infections,nonbacterial systemic inflammatory reactions,excessive diuresis,gastrointestinal hemorrhage,diarrhea or nephrotoxic agents.Each type of renal disease has a specific treatment approach ranging from repletion of the vascular system to renal replacement therapy.The treatment of choice in type 1 hepatorenal syndrome is a combination of vasoconstrictor with albumin infusion,which is effective in about 50% of patients.The second-line treatment of HRS involves a transjugular intrahepatic portosystemic shunt,renal vasoprotection or systems of artificial liver support.

    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.

    The relationships between chronic liver diseases and trace element (TE) contents are debated. Particularly, no defined data are available about the TE levels in viral liver disease patients with or without malnutrition. In this study we evaluated blood and plasma levels of various trace elements in patients with HCV-related chronic liver disease, at different stages of liver damage (8 patients with chronic hepatitis and 32 with liver cirrhosis) with or without malnutrition. We also studied 10 healthy volunteers as control group. We found that cirrhotic subjects had a significant decrease of blood levels of Zn and Se, independently on the nutritional status, whereas plasma levels of Fe were significantly reduced only in malnourished cirrhotic patients. Our data indicate that liver impairment is the main cause of the blood decrease of Se and Zn levels in patients with non alcoholic liver disease, whereas the malnutrition affects Fe levels only.

    Background. In the healthy liver there is a splanchnic net-uptake of lactate caused by gluconeogenesis. It has previously been shown that patients with acute liver failure in contrast have a splanchnic release of lactate caused by a combination of accelerated glycolysis in the splanchnic region...... and a reduction in hepatic gluconeogenesis. Aims. The aims of the present study were to investigate lactate metabolism and kinetics in patients with chronic liver disease compared with a control group with normal liver function. Methods. A total of 142 patients with chronic liver disease and 14 healthy controls...... underwent a liver vein catheterization. Blood samples from the femoral artery and the hepatic and renal veins were simultaneously collected before and after stimulation with galactose. Results. The fasting lactate levels, both in the hepatic vein and in the femoral artery, were higher in the patients than...

    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.

  10. Role of cannabinoids in chronic liver diseases

    2008-01-01

    Cannabinoids are a group of compounds acting primarily via CB1 and CB2 receptors. The expression of cannabinoid receptors in normal liver is low or absent. However, many reports have proven up-regulation of the expression of CB1 and CB2 receptors in hepatic myofibroblasts and vascular endothelial cells, as well as increased concentration of endocannabinoids in liver in the course of chronic progressive liver diseases. It has been shown that CB1 receptor signalling exerts profibrogenic and proinflammatory effects in liver tissue, primarily due to the stimulation of hepatic stellate cells, whereas the activation of CB2 receptors inhibits or even reverses liver fibrogenesis. Similarly, CB1 receptor stimulation contributes to progression of liver steatosis. In end-stage liver disease, the endocannabi-noid system has been shown to contribute to hepatic encephalopathy and vascular effects, such as portal hypertension, splanchnic vasodilatation, relative pe-ripheral hypotension and probably cirrhotic cardiomy-opathy. So far, available evidence is based on cellular cultures or animal models. Clinical data on the effects of cannabinoids in chronic liver diseases are limited. However, recent studies have shown the contribution of cannabis smoking to the progression of liver fibrosis and steatosis. Moreover, controlling CB1 or CB2 signal-ling appears to be an attractive target in managing liver diseases.

    Full Text Available Background. There continues to be uncertainty on the ideal treatment of pruritus in chronic liver disease. The aim of this study was to gather the latest information on the evidence-based management of pruritus in chronic liver disease. Methodology. A literature search for pruritus in chronic liver disease was conducted using Pubmed and Embase database systems using the MeSH terms “pruritus,” “chronic liver disease,” “cholestatic liver disease,” and “treatment.” Results. The current understanding of the pathophysiology of pruritus is described in addition to detailing research into contemporary treatment options of the condition. These medical treatments range from bile salts, rifampicin, and opioid receptor antagonists to antihistamines. Conclusion. The burden of pruritus in liver disease patients persists and, although it is a common symptom, it can be difficult to manage. In recent years there has been greater study into the etiology and treatment of the condition. Nonetheless, pruritus remains poorly understood and many patients continue to suffer, reiterating the need for further research to improve our understanding of the etiology and treatment for the condition.

    2006-01-01

    Interleukin (IL)-10 is an important immunoregulatory cytokine produced by many cell populations. Numerous investigations suggest that IL-10 plays a major role in chronic liver diseases. IL-10 gene polymorphisms are possibly associated with liver disease susceptibility or severity. Recombinant human IL-10 has been produced and is currently tested in clinical trials. These trials may give new insights into the immunobiology of IL-10 and suggest that the IL-10/IL-10 receptor system may become a new therapeutic target.

    1997-01-01

    This study explores and describes experiences of chronic liver disease from the patient's perspective. No qualitative research studies appear to have examined the experiences of these patients. In-depth focused interviews and grounded theory data collection and data analysis methods were used. A two-stage theoretical framework (becoming ill, and not living) of the experience of transcending chronic liver disease is presented. Sociological and psychological literature on common sense models of health and illness are briefly reviewed. Several suggestions for further research are made. The way in which this qualitative research study is leading to a quantitative and qualitative appraisal of the psychological adjustment in end-stage chronic liver disease patients is outlined.

    Since liver function is changed by chronic liver diseases, chronic liver disease can lead to different hemorheological alterations during the course of the progression. This study aims to compare alterations in whole blood viscosity in patients with chronic liver disease, focusing on the gender effect. Chronic liver diseases were classified into three categories by patient's history, serologic markers, and radiologic findings: nonalcoholic fatty liver disease (NAFLD) (n = 63), chronic viral hepatitis B and C (n = 50), and liver cirrhosis (LC) (n = 35). Whole blood viscosity was measured by automated scanning capillary tube viscometer, while liver stiffness was measured by transient elastography using FibroScan®. Both systolic and diastolic whole blood viscosities were significantly lower in patients with LC than NAFLD and chronic viral hepatitis (P chronic viral hepatitis. Our data suggest that whole blood viscosity test can become a useful tool for classifying chronic liver disease and determining the prognosis for different types of chronic liver diseases.

    2008-01-01

    A structured literature review was performed to detail the frequency and etiology of chronic liver disease (CLD) in Aboriginal North Americans. 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.

    Vitamin D is an important secosteroid hormone with known effect on calcium homeostasis,but recently there is increasing recognition that vitamin D also is involved in cell proliferation and differentiation,has immunomodulatory and anti-inflammatory properties.Vitamin D deficiency has been frequently reported in many causes of chronic liver disease and has been associated with the development and evolution of non-alcoholic fatty liver disease(NAFLD)and chronic hepatitis C(CHC)virus infection.The role of vitamin D in the pathogenesis of NAFLD and CHC is not completely known,but it seems that the involvement of vitamin D in the activation and regulation of both innate and adaptive immune systems and its antiproliferative effect may explain its importance in these liver diseases.Published studies provide evidence for routine screening for hypovitaminosis D in patients with liver disease.Further prospectives studies demonstrating the impact of vitamin D replacement in NAFLD and CHC are required.

    Full Text Available Oxidative stress is a common feature observed in a wide spectrum of chronic liver diseases including viral hepatitis, alcoholic, and nonalcoholic steatohepatitis. The nicotinamide adenine dinucleotide phosphate (NADPH oxidases (NOXs are emerging as major sources of reactive oxygen species (ROS. Several major isoforms are expressed in the liver, including NOX1, NOX2, and NOX4. While the phagocytic NOX2 has been known to play an important role in Kupffer cell and neutrophil phagocytic activity and inflammation, the nonphagocytic NOX homologues are increasingly recognized as key enzymes in oxidative injury and wound healing. In this review, we will summarize the current advances in knowledge on the regulatory pathways of NOX activation, their cellular distribution, and their role in the modulation of redox signaling in liver diseases.

    2004-04-01

    Evidence regarding the outcomes of viral super-infection in patients with chronic liver disease and practical strategies for hepatitis A and B vaccination of these individuals are reviewed. Patients with acute hepatitis A and chronic hepatitis B have a more severe clinical course and a higher death rate compared with otherwise healthy individuals with hepatitis A, and these differences are most pronounced in older patients and those with histological evidence of chronic hepatitis or cirrhosis, rather than in asymptomatic hepatitis B carriers. Patients with acute hepatitis A super-infection and chronic hepatitis C have an increased risk of fulminant hepatitis and death. In addition, patients with other chronic liver diseases also appear to be at increased risk for more severe disease with superimposed hepatitis A. Patients with chronic hepatitis B and hepatitis C virus co-infection have more severe laboratory abnormalities, more severe histological disease, a greater frequency of cirrhosis and complications of cirrhosis, and a higher incidence of hepatocellular carcinoma. Vaccines for both hepatitis A and B are safe and effective if used early in the course of chronic liver disease. Hepatitis A and B vaccination should be part of the routine management of patients with chronic liver disease, preferably as early as possible in the natural course of their disease.

Eighty patients were diagnosed over a 6-year period. Twenty-two had biopsy proven cirrhosis while 58 others had portal hypertension with clinical and biochemical evidence of chronic liver disease. The commonest aetiology was alcohol (36%), followed by the idiopathic variety and hepatitis B. The male to female ratio was 4.4:1. Indians had a high prevalence of alcohol-associated chronic liver disease. Overall, ascites was the commonest presentation. Eight patients presented with hepatocellular carcinoma. Spontaneous bacterial peritonitis was diagnosed in 13% of patients undergoing abdominal paracentesis. Gallstones were detected in 37% of patients who underwent ultrasonography. Diabetes mellitus and peptic ulcer disease were noted in 22% and 31% of patients respectively.

  6. Neuroinflammation and neurological alterations in chronic liver diseases

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Several million people with chronic liver diseases (cirrhosis, hepatitis show neurological alterations, named hepatic encephalopathy (HE with cognitive and motor alterations that impair quality of life and reduces life span. Inflammation acts synergistically with hyperammonemia to induce cognitive and motor alterations in patients with chronic liver disease and minimal hepatic encephalopathy (MHE. Previous studies in animal models have suggested that neuroinflammation is a major player in HE. This would also be the case in patients with liver cirrhosis or hepatitis C with HE. Rats with MHE show microglial activation and neuroinflammation that is associated with cognitive impairment and hypokinesia. The anti-inflammatory drug ibuprofen reduces microglial activation and neuroinflammation and restores cognitive and motor functions in rats with MHE. Chronic hyperammonemia per se induces neuroinflammation. Both peripheral inflammation and hyperammonemia would contribute to neuroinflammation in chronic liver failure. Therefore, neuroinflammation may be a key therapeutic target to improve the cognitive and motor alterations in MHE and overt HE. Identifying new targets to reduce neuroinflammation in MHE without inducing secondary effects would serve to develop new therapeutic tools to reverse the cognitive and motor alterations in patients with HE associated with chronic liver diseases.

    The development of liver cirrhosis and portal hypertension (PH), one of its major complications, are structural and functional alterations of the liver, occurring in many patients with chronic liver diseases (CLD). Actually the progressive deposition of hepatic fibrosis has a key role in the prognosis of CLD patients. The subsequent development of PH leads to its major complications, such as ascites, hepatic encephalopathy, variceal bleeding and decompensation. Liver biopsy is still considered the reference standard for the assessment of hepatic fibrosis, whereas the measurement of hepatic vein pressure gradient is the standard to ascertain the presence of PH and upper endoscopy is the method of choice to detect the presence of oesophageal varices. However, several non-invasive tests, including elastographic techniques, are currently used to evaluate the severity of liver disease and predict its prognosis. More recently, the measurement of the spleen stiffness has become particularly attractive to assess, considering the relevant role accomplished by the spleen in splanchnic circulation in the course of liver cirrhosis and in the PH. Moreover, spleen stiffness as compared with liver stiffness better represents the dynamic changes occurring in the advanced stages of cirrhosis and shows higher diagnostic performance in detecting esophageal varices. The aim of this review is to provide an exhaustive overview of the actual role of spleen stiffness measurement as assessed by several elastographic techniques in evaluating both liver disease severity and the development of cirrhosis complications, such as PH and to highlight its potential and possible limitations.

  10. Metabolic Disturbances in Children with Chronic Liver Disease

    2014-04-01

    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

    Full Text Available Tuberculous peritonitis (TBP remains a major medical problem in many developing countries, wherein the incidence of tuberculosis (TB is still high. Since the clinical presentation may be insidious and variable, diagnosis of TBP may be delayed or missed, resulting in undue patient morbidity and mortality. Tests frequently associated with TB such as chest radiograph and Mantoux test are not usually sensitive enough for the diagnosis of TBP. The diagnosis becomes all the more difficult in the presence of chronic liver disease and/or renal failure, since the ascitic fluid may not be of the exudative type and lymphocytosis may not be the predominant cell picture. We present here three cases of TBP in diabetic Saudi patients on maintenance hemodialysis who also had associated chronic liver disease. All three patients responded satisfactorily to standard anti-tuberculous therapy. We stress that high index of suspicion is required to establish early diagnosis of TBP particularly in patients with chronic renal and/or liver disease. Laparoscopy with tissue biopsy for histology and, microbiological examination including culture are the most sensitive and specific diagnostic procedures.

    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

    BACKGROUND Viral replication in blood cells with nucleuses may lead to the damage of lymphocytes genetic apparatus and the beginning of immunopathological reactions.AIM Of this investigation is to reveal the damage to peripheral blood lymphocytes (PBL)DNA in the patients with chronic liver diseases.MATERIALS AND METHODS Sixteen-ninepatients with chronic liver diseases (37 patients with chronic viral hepatitis, 2 patients with liver cirrhosis of mixed etiology (alcohol + virus G),30 women with primary biliary cirrhosis-PBC)were examined. The condition of DNA structure of PBL-was measured by the fluorescenceanalysis of DNA unwinding (FADU) technique with modification. Changes of fluorescence (in %) reflected the DNA distractions degree (thepresence of DNA single-stranded breaks and alkalinelabile sights).RESULTS AND CONCLUSION . The quantity of DNA single-stranded breaks and alkalinelabile sightsin DNA in all patients with chronic viral hepatitis .didnt differ from the control group,excluding the patients with chronic hepatitis (CH) C + G. Patients with HGV and TTV monoinfection had demonstrated the increase of the DNA single-stranded breaks PBL quantity.This fact may be connected with hypothesisabout the viruses replication in white blood cells discussed in the literature. Tendency to increase quantity of DNA PBL damages in the patients with primary biliary cirrhosis (PBC) accordingly to the alkaline phosphatase activity increase was revealed. Significant decrease of the DNA single-stranded breaks and alkalinelabile sights in the PBC patients that were treated with prednison was demonstrated. Probably, the tendency to increase the quantity of DNA singlestranded breaks and alkalinelabile sights in lymphocytes of the PBC patients was depended on the surplus of the blood bile acid content.

  14. Hepatitis A and B superimposed on chronic liver disease: vaccine-preventable diseases.

    A number of studies have demonstrated that the acquisition of hepatitis A or hepatitis B in patients with chronic liver disease is associated with high rates of morbidity and mortality. Superimposition of acute hepatitis A in patients with chronic hepatitis C has been associated with a particularly high mortality rate, and chronic hepatitis B virus coinfection with hepatitis C virus is associated with an accelerated progression of chronic liver disease to cirrhosis, decompensated liver disease and hepatocellular carcinoma. With the availability of vaccines against hepatitis B and hepatitis A since 1981 and 1995, respectively, these are vaccine-preventable diseases. Studies have confirmed that hepatitis A and hepatitis B vaccines are safe and immunogenic in patients with mild to moderate chronic liver disease. However, hepatitis A and B vaccination is less effective in patients with advanced liver disease and after liver transplantation. These observations have led to the recommendation that patients undergo hepatitis A and B vaccination early in the natural history of their chronic liver disease. Vaccination rates are low in clinical practice, and public health and educational programs are needed to overcome barriers to facilitate timely implementation of these recommendations.

    Full Text Available Background/Aim: We aimed to analyze serum hepcidin level in children with chronic liver disease (CLD and its relationship with serum cytokines level, liver function tests, hepatic iron content, and liver fibrosis. Patients and Methods: The study included 34 children with CLD, and 15 age- and gender-matched healthy children. Serum hepcidin, ferritin, iron level, interleukin-6 (IL-6, transforming growth factor-β (TGF-β , total oxidant status (TOS, and antioxidant status (TAS were studied in all patients and in the control group. Liver iron content (LIC was measured from the liver biopsy specimen. Results: Serum ferritin levels were higher in patients with CLD than control group (100.1 ± 98.2 ng/mL vs 50.5 ± 32.2 ng/mL, P = 0.016. No significant difference was found in hepcidin levels. Hepcidin levels in children with CLD was positively correlated with ferritin (r = 0.75, P = 0.001, pediatric end-stage liver disease (PELD score (r = 0.56, P = 0.001, TAS (r = 0.42,P = 0.02, but negatively correlated with albumin level (r = −0.45,P = 0.008. Transferrin saturation and hepcidin:ferritin ratio were significantly low in patients with severe fibrosis compared with patients with mild/without fibrosis (15.5 ± 5.5 vs 34.3 ± 30.1, P = 0.017 and 1 ± 0.5 vs 1.9 ± 1.4,P = 0.04, respectively. Conclusion: Serum hepcidin levels in children with CLD reflect both liver functions and TAS, and severe fibrosis is associated with low hepcidin:ferritin ratio in children with CLD.

    A method has been developed to measure the in vitro production of immunoglobulin (Ig) by liver biopsy specimens. Five to 30 mg of liver tissue was cultured for 24 h in Dulbecco's modified Eagle's medium/10% foetal calf serum (FCS) containing radiolabelled leucine (L-[4,5-3H] leucine). The culture medium was collected, centrifuged and the supernatant dialysed to remove labelled leucine. The residual radioactivity was a measure of newly synthesized 3H-labelled proteins released into the medium. The quantity of IgG was determined by immunoprecipitation with monospecific antisera to IgG heavy chains. The presence of IgG in the supernatant was confirmed by chromatography on protein-A Sepharose column. In 6 biopsies without evidence of active inflammation (4 normal and 2 fatty liver by histological criteria) less than 1% of the protein synthesized was IgG. In contrast in the presence of active inflammation in 4 cases of alcoholic hepatitis the IgG percentage ranged from 2 to 6%. Maximal levels of IgG production were detected in 3 cases of chronic active hepatitis (CAH) and ranged from 5 to 30%. The increased Ig synthesis by the liver in alcoholic hepatitis and CAH is presumed to be an index of the intrahepatic host response and may have important implications for mechanisms of liver damage in these diseases.

  18. From liver biopsy to non-invasive markers in evaluating fibrosis in chronic liver disease

    Full Text Available Chronic liver disease is a late stage of progressive hepatic fibrosis. It consists of functional and structural disruptions in most chronic liver diseases. An accurate diagnosis allows us to establish the degree of fibrosis and the stage of the disease, the prognosis of the patient and to predict a treatment response. Despite the fact that liver biopsy is considered a gold standard, noninvasive methods for diagnosing liver fibrosis have gained more and more importance. Whether we talk about serum biomarkers or imagistic methods from transient elastography to 3-D magnetic resonance elastography, the question remains: are these useful or useless? Serum biomarkers represent blood components that can reflect liver histological changes, thus they can monitor the continuous process of fibrosis. These can be subcategorized in direct (that show extracellular matrix turnover and indirect markers (that reflect disturbances in the hepatic function. However these markers alone are not as accurate in the staging of fibrosis, only help differentiate patients without or with low grade of fibrosis from those with significant fibrosis and cannot be considered alone in the diagnosis of liver fibrosis. Imagistic methods include: ultrasound-based transient elastography, magnetic resonance elastography (MRE, 2D-shear wave elastography, acoustic radiation impulse imaging (ARFI and cross sectional imaging, the first being the most used. Using a combination of non-invasive tools allows us to diminish the number of patients in need of liver biopsy. However, the patient must always be informed of the advantages and disadvantages of each method and its limitations.

    Chronic liver diseases (CLD) alter the kinetics of drugs. Despite dosage adjustment is based on Child-Pugh scores, there are no available recommendations and/or algorithms of reference to facilitate dosage regimens. A literature review about dose adjustment of the drugs from the hospital guide -which are included in the list of the WHO recommended drugs to be avoided or used with caution in patients with liver disease- was carried out. The therapeutic novelties from the last few years were also included. In order to do so, the summary of product characteristics (SPC), the database DrugDex-Micromedex, the WHO recommendations and the review articles from the last 10 years in Medline were reviewed. Moreover, the kinetic parameters of each drug were calculated with the aim of establishing a theoretical recommendation based on the proposal of Delcò and Huet. Recommendations for 186 drugs are presented according to the SPC (49.5%), DrugDex-Micromedex (26.3%) and WHO (18.8%) indications; six recommendations were based on specific publications; the theoretical recommendation based on pharmacokinetic parameters was proposed in four drugs. The final recommendations for clinical management were: dosage modification (26.9%), hepatic/analytical monitoring of the patient (8.6%), contraindication (18.8%), use with caution (19.3%) and no adjustment required (26.3%). In this review, specific recommendations for the practical management of patients with chronic liver disease are presented. It has been elaborated through a synthesis of the published bibliography and completed by following a theoretical methodology.

    Full Text Available Complementary and alternative medicine soughts and encompasses a wide range of approaches; its use begun in ancient China at the time of Xia dynasty and in India during the Vedic period, but thanks to its long-lasting curative effect, easy availability, natural way of healing, and poor side-effects it is gaining importance throughout the world in clinical practice. We conducted a review describing the effects and the limits of using herbal products in chronic liver disease, focusing our attention on those most known, such as quercetin or curcumin. We tried to describe their pharmacokinetics, biological properties, and their beneficial effects (as antioxidant role in metabolic, alcoholic, and viral hepatitis (considering that oxidative stress is the common pathway of chronic liver diseases of different etiology. The main limit of applicability of CAM comes from the lacking of randomized, placebo-controlled clinical trials giving a real proof of efficacy of those products, so that anecdotal success and personal experience are frequently the driving force for acceptance of CAM in the population.

    AIM: Quality of life (QOL) is a concept that incorporates many aspects of life beyond "health". The chronic liver disease questionnaire (CLDQ) was developed to evaluate the impact of chronic liver diseases (CLD) on QOL. The objectives of this study were to translate and validate a liver specific questionnaire, the CLDQ.METHODS: The CLDQ was formally translated from the original version to Thai language with permission. The translation process included forward translation, back translation, cross-cultural adaptation and a pretest. Reliability and validity of the translated version was examined in CLD patients. Enrolled subjects included CLD and normal subjects with age- and sex-matched. Collected data were demography,physical findings and biochemical tests. All subjects were asked to complete the translated versions of CLDQ and SF-36, which was previously validated. Cronbach's alpha and test-retest were performed for reliability analysis. One-way Anova or non-parametric method was used to determine discriminant validity. Spearman's rank correlation was used to assess convergent validity. P-value <0.05 was considered statistically significant.RESULTS: A total of 200 subjects were recruited into the study, with 150 CLD and 50 normal subjects. Mean ages (SD) were 47.3(11.7) and 49.1(8.5) years, respectively. The number of chronic hepatitis: cirrhosis was 76:74, and the ratio of cirrhotic patients classified as Child A:B:C was 37(50%): 26(35%): 11(15%). Cronbach's alpha of the overall CLDQ scores was 0.96 and of all domains were higher than0.93. Item-total correlation was >0.45. Test-retest reliability done at 1 to 4 wk apart was 0.88 for the average CLDQ score and from 0.68 to 0.90 for domain scores. The CLDQ was found to have discriminant validity. The highest scores of CLDQ domains were in the normal group, scores were lower in the compensated group and lowest in the decompensated group. The significant correlation between domains of the CLDQ and SF-36 was found

    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.

Chronic liver diseases are frequently associated with hematological abnormalities. Anemia of diverge etiology occurs in about 75% patients with DCLD ( 36. This can ultimately culminate in grave complications. AIM OF THE STUDY: To detect various abnormalities in Red Blood Cells and to assess the type of anemia in DCLD. METHODS: The study was conducted in 50 patients of DCLD, in Meenakshi Medical College. A detailed History, clinical examination and also Ultrasound Abdomen, GI endoscopy to establish DCLD and complete Red Blood Cell assessment was done. RESULTS AND OBSERVATION : Among the 50 patients, 40 patients (80% had anemia and only 10 pts had normal h emoglobin above 13 gms%. About 15 patients (30% had severe Anemia of less than 6 gm%. Among the 40 patients, 25 patients had normocytic normochronic anemia, 10 patients had microcytic anemia, and 4 patients had macrocytosis and only one had dimorphic anem ia. CONCLUSION : Most common Red Blood Cell abnormality in DCLD is anemia (80% and most common anemia is normochronic normocytic anemia (62.5%, while microcytic anemia and macrocytosis were common among females and Alcoholics, respectively

    To study the morphologic interrelation of hepatocytes with the replication of hepatitis B vius (HBV) and immunocompetent cells in chronic active liver disease(CALD), organ cultures were prepared from liver biopsy specimens. Replication of hepatitis B core antigen (HBcAg) appears to occur in the nucleus of the hepatocyte in close association with intranuclear electron-dense strands and sometimes intranucleolar matrixes (likely HBcAg genomes), and cytoplasmic maturation of the HBcAg takes place in the preautolytic condition of host hepatocytes. Immunocompetent cells became progressively autolyzed in the early period of cultures. No difference in progression of hepatocyte injury in tissues from normal subjects and from hepatitis B surface antigen (HBsAg)-positive and HBsAg-negative patients with CALD may suggest that intracellular synthesis of HBV alone is not cytopathic to host hepatocytes. This model is promising for the study of HBV replication and development, and also for testing the efficacy of new antiviral agents against the virus.

    Jack X Q Pang

    Full Text Available BACKGROUND: 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. METHODS: 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. RESULTS: 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%. CONCLUSIONS: 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.

    Chronic viral hepatitis is a common disease in the general population.During chronic hepatitis,the prognosis and clinical management are highly dependent on the extent of liver fibrosis.The fibrosis evaluation can be performed by FibroTest (using serological markers),by Elastography or FibroScan (a noninvasive percutaneous technique using the elastic properties of the hepatic tissue) and by liver biopsy (LB),considered to be the "gold standard".Currently,there are three techniques for performing LB: percutaneous,transjugular and laparoscopic.The percutaneous LB can be performed blind,ultrasound (US) guided or US assisted.There are two main categories of specialists who perform LB: gastroenterologists (hepatologists) and radiologists,and the specialty of the individual who performs the LB determines if the LB is performed under ultrasound guidance or not.There are two types of biopsy needles used for LB: cutting needles (Tru-Cut,Vim-Silverman) and suction needles (Menghini,Klatzkin,Jamshidi).The rate of major complications after percutaneous LB ranges from 0.09% to 2.3%,but the echoguided percutaneous liver biopsy is a safe method for the diagnosis of chronic diffuse hepatitis (costeffective as compared to blind biopsy) and the rate of complications seems to be related to the experience of the physician and the type of the needle used (Menghini type needle seems to be safer).Maybe,in a few years we will use non-invasive markers of fibrosis,but at this time,most authorities in the field consider that the LB is useful and necessary for the evaluation of chronic hepatopathies,despite the fact that it is not a perfect test.

  11. Non-invasive assessment of liver fibrosis in chronic liver diseases: Implementation in clinical practice and decisional algorithms

    2009-01-01

    Chronic hepatitis B and C together with alcoholic and non-alcoholic fatty liver diseases represent the major causes of progressive liver disease that can eventually evolve into cirrhosis and its end-stage complications, including decompensation, bleeding and liver cancer. Formation and accumulation of fibrosis in the liver is the common pathway that leads to an evolutive liver disease. Precise definition of liver fibrosis stage is essential for management of the patient in clinical practice since the presence of bridging fibrosis represents a strong indication for antiviral therapy for chronic viral hepatitis, while cirrhosis requires a specific follow-up including screening for esophageal varices and hepatocellular carcinoma. Liver biopsy has always represented the standard of reference for assessment of hepatic fibrosis but it has some limitations being invasive, costly and prone to sampling errors. Recently, blood markers and instrumental methods have been proposed for the non-invasive assessment of liver fibrosis. However, there are still some doubts as to their implementation in clinical practice and a real consensus on how and when to use them is not still available. This is due to an unsatisfactory accuracy for some of them, and to an incomplete validation for others. Some studies suggest that performance of non-invasive methods for liver fibrosis assessment may increase when they re combined. Combination algorithms of non-invasive methods for assessing liver fibrosis may represent a rational and reliable approach to implement noninvasive assessment of liver fibrosis in clinical practice and to reduce rather than abolish liver biopsies.

    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 Chronic liver dysfunction or injury is a serious health problem worldwide. Chronic liver disease involves a wide range of liver pathologies that include fatty liver, hepatitis, fibrosis, cirrhosis, and hepatocellular carcinoma. The efficiency of current synthetic agents in treating chronic liver disease is not satisfactory and they have undesirable side effects. Thereby, numerous medicinal herbs and phytochemicals have been investigated as complementary and alternative treatments for chronic liver diseases. Since some herbal products have already been used for the management of liver diseases in some countries or regions, a systematic review on these herbal medicines for chronic liver disease is urgently needed. Herein, we conducted a review describing the potential role, pharmacological studies and molecular mechanisms of several commonly used medicinal herbs and phytochemicals for chronic liver diseases treatment. Their potential toxicity and side effects were also discussed. Several herbal formulae and their biological effects in chronic liver disease treatment as well as the underlying molecular mechanisms are also summarized in this paper. This review article is a comprehensive and systematic analysis of our current knowledge of the conventional medicinal herbs and phytochemicals in treating chronic liver diseases and on the potential pitfalls which need to be addressed in future study.

    In chronic liver disease leading to fibrosis, hepatic stellate cells (HSC) differentiate into myofibroblasts. Myofibroblastic HSC have taken center stage during liver fibrogenesis, due to their remarkable synthesis of extracellular matrix proteins, their secretion of profibrogenic mediators and their contribution to hypertension, due to elevated contractility. MicroRNAs (miRNAs) are small, noncoding RNA molecules of 19-24 nucleotides in length. By either RNA interference or inhibition of translational initiation and elongation, each miRNA is able to inhibit the gene expression of a wide panel of targeted transcripts. Recently, it was shown that altered miRNA patterns after chronic liver disease highly affect the progression of fibrosis by their potential to target the expression of extracellular matrix proteins and the synthesis of mediators of profibrogenic pathways. Here, we underline the role of miRNAs in the interplay of the profibrogenic cell communication pathways upon myofibroblastic differentiation of hepatic stellate cells in the chronically injured liver.

    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 BackgroundLiver biopsy is recommended as the gold standard method for assessing the stage of liver fibrosis in patients with chronic liver disease. However, it is invasive, with potential risks and complications. Elastography is an ultrasound technique that provides information of changes in the liver tissue, evaluating tissue elasticity and acoustic radiation force impulse is one of the available techniques.ObjectiveThe main objective of this study was to evaluate the sensitivity and specificity of acoustic radiation force impulse comparing to liver biopsy to evaluate fibrosis in patients with chronic hepatitis C virus and nonalcoholic fatty liver disease.MethodsTwenty four patients were included, everyone underwent liver biopsy and acoustic radiation force impulse, and the results were compared with values described in the literature by several authors.ResultsIn the population of patients with chronic hepatitis C, our data were better correlated with data published by Carmen Fierbinteanu-Braticevici et al., with an accuracy of 82.4%, sensitivity of 71.4% and specificity of 90%. For nonalcoholic fatty liver disease, our data were better correlated with data published by Masato Yoneda et al., with an accuracy of 85.7%, sensitivity 80% and specificity of 100%.ConclusionAcoustic radiation force impulse is a method with good accuracy to distinguish initial fibrosis from advanced fibrosis in hepatitis C virus and nonalcoholic fatty liver disease and can replace biopsy in most cases.

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

    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.

    AIM: To explore the relationship between clinical findings of patients with chronic liver diseases and the pathologic grading and staging of liver tissues.METHODS: The inflammatory activity and fibrosis of consecutive liver biopsies from 200 patients were determined according to the diagnosis criteria of chronic hepatitis in China established in 1995. A comparative analysis was carried out for 200 patients with chronic liver diseases by comparing their clinical manifestations, serum biochemical markers with the grading and staging of liver tissues.RESULTS: It was revealed that age, index of clinical symptoms and physical signs were obviously relevant to the pathologic grading and staging of liver tissues (P<0.05). Blood platelet, red blood cells, aspartate aminotransferase (AST),N-terminal procollagen Ⅲ (PⅢ NP) were apparently correlated with the degree of inflammation. PGA (prothrombin time,GGT, apoprotein A1) index, PGAA (PGA+△2-macroglobublin)index, albumin and albumin/globulin were relevant to both inflammation and fibrosis. Hyaluronic acid (HA) was an accurate variable for the severity of hepatic inflammation and fibrosis. The combination of serum markers for fibrosis could increase the diagnostic accuracy. It was notable that viral replication markers were not relevant to the degree of inflammation and fibrosis.CONCLUSION: There is a good correlation between clinical findings and the pathologic grading and staging of liver tissues, which may give aid to the noninvasive diagnosis of liver fibrosis.

    Full Text Available Objective. To compare and analyze the relevance and applied value of chronic liver disease questionnaire (CLDQ and Traditional Chinese Medicine liver disease questionnaire (TCMLDQ in patients with posthepatitic cirrhosis. Methods. The data of 146 patients' scales of CLDQ and TCMLDQ which based on the characteristics of chinese medical symptoms were collected. We made comparative analysis of the relationship between these two scales by the linear regression model and canonical correlation method and evaluated the advantages and disadvantages of two scales about its items setting and dimension definition. Result. There is a negative correlation in total scores between the two scales and the linear regression equation: CLDQ=239.38−1.232TCMLDQ. The further canonical correlation analysis was used to analyze the two extracted canonical correlative variables with significances (P<0.05, and the results showed that the overall negative correlation between the two scales mainly came from contributions of both the four dimensions of TCMLDQ (CS, GSYX, GYPX, and OS and the five dimensions of CLDQ (AS, FA, SS, AC, and EF. Conclusion. These two scales have good consistency in the evaluation of severity and life quality of liver cirrhosis patients, so we suggested that TCMLDQ can be used to evaluate the severity and life quality of patients with posthepatitic cirrhosis.

    Thrombocytopenia (platelet count management of these patients. The prevalence of this manifestation ranges from 6% among non-cirrhotic patients with chronic liver disease to 70% among patients with liver cirrhosis. It has also been shown that the severity of liver disease is associated with both prevalence and level of thrombocytopenia. Its development is often multifactorial, although thrombopoietin is thought to be a major factor. The discovery of and ability to clone thrombopoietin led to new treatment opportunities for this clinical manifestation. This review discusses data on the three most important thrombopoietin receptor agonists: eltrombopag, avatrombopag, and romiplostim. Currently, only eltrombopag is approved for usage among patients with thrombocytopenia and chronic hepatitis C virus infection in order to initiate and maintain interferon-based antiviral treatment. Nevertheless, the optimal management of hematologic abnormalities among patients with chronic liver disease, and its risk for bleeding complications, is still a matter of discussion. Thrombocytopenia definitely contributes to hemostatic defects but is often counterbalanced by the enhanced presence of procoagulant factors. Therefore, a thorough assessment of the patient's risk for thrombotic events is essential when the use of thrombopoietin receptor agonists is considered among patients with chronic liver disease and thrombocytopenia.

  5. Female hepatology: Favorable role of estrogen in chronic liver disease with hepatitis B virus infection

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Chronic hepatitis B virus (HBV) infection is the most common cause of hepatic fibrosis and hepatocellular carcinoma (HCC), mainly as a result of chronic necroinflammatory liver disease. A characteristic feature of chronic hepatitis B infection, alcoholic liver disease and nonalcoholic fatty liver disease (NAFLD) is hepatic steatosis. Hepatic steatosis leads to an increase in lipid peroxidation in hepatocytes, which, in turn, activates hepatic stellate cells (HSCs). HSCs are the primary target cells for inflammatory and oxidative stimuli, and these cells produce extracellular matrix components.Chronic hepatitis B appears to progress more rapidly in males than in females, and NAFLD, cirrhosis and HCC are predominately diseases that tend to occur in men and postmenopausal women. Premenopausal women have lower hepatic iron stores and a decreased production of proinflammatory cytokines. Hepatic steatosis has been observed in aromatase-deficient mice, and has been shown to decrease in animals after estradiol treatment. Estradiol is a potent endogenous antioxidant which suppresses hepatic fibrosis in animal models, and attenuates induction of redox sensitive transcription factors, hepatocyte apoptosis and HSC activation by inhibiting a generation of reactive oxygen species in primary cultures. Variant estrogen receptors are expressed to a greater extent in male patients with chronic liver disease than in females. These lines of evidence suggest that the greater progression of hepatic fibrosis and HCC in men and postmenopausal women may be due, at least in part, to lower production of estradiol and a reduced response to the action of estradiol. A better understanding of the basic mechanisms underlying the sex-associated differences in hepatic fibrogenesis and carciogenesis may open up new avenues for the prevention and treatment of chronic liver disease.

    AIM: To investigate the factors contributing to healthrelated quality of life (HRQL) in chronic liver disease (CLD).METHODS: Patients with CLD and age- and sexmatched normal subjects performed the validated Thai versions of the short-form 36 (SF-36) by health survey and chronic liver disease questionnaire (CLDQ). Stepwise multiple regression analysis was used to assess the impact of disease severity, demography, causes of CLD,socioeconomic factors, and self-rating health perception on HRQL.RESULTS: Two-hundred and fifty patients with CLD and fifty normal subjects were enrolled into the study. Mean age and the numbers of low educated, unemployed,blue-collar career and poor health perception increased significantly from chronic hepatitis to Child's Classes A to B to C. Advanced stage of CLD was related to deterioration of HRQL. Increasing age and female reduced physical health area. Low socioeconomic factors and financial burden affected multiple areas of HRQL.In overall, the positive impact of self-rating health perception on HRQL was consistently showed.CONCLUSION: Advanced stages of chronic liver disease, old age, female sex, low socioeconomic status and financial burden are important factors reducing HRQL. Good health perception improves HRQL regardless of stages of liver disease.

    Purpose The purpose of this study was to define the role of cyclooxygenase-2 inhibitors (COX-2i) in reducing hepatic fibrosis in pediatric patients with chronic liver disease. Materials and Methods From September 2009 to September 2010, patients over 2 years old who visited our outpatient clinic for follow-up to manage their chronic liver disease after Kasai portoenterostomy for biliary atresia, were included in this study. Volunteers were assigned to the study or control groups, according to their preference. A COX-2i was given to only the study group after obtaining consent. The degree of hepatic fibrosis (liver stiffness score, LSS) was prospectively measured using FibroScan, and liver function was examined using serum analysis before and after treatment. After 1 year, changes in LSSs and liver function were compared between the two groups. Results Twenty-five patients (18 females and 7 males) were enrolled in the study group. The control group included 44 patients (26 females and 18 males). After 1 year, the least square mean values for the LSSs were significantly decreased by 3.91±0.98 kPa (p=0.004) only in the study group. Serum total bilirubin did not decrease significantly in either group. Conclusion COX-2i treatment improved the LSS in patients with chronic liver disease after Kasai portoenterostomy for biliary atresia. PMID:27189282

    Full Text Available Background/Aim: To study the oxidative stress status in children with cholestatic chronic liver disease by determining activities of glutathione peroxidase (GPx, superoxide dismutase (SOD and catalase (CAT in liver tissue. Materials and Methods: A total of 34 children suffering from cholestatic chronic liver disease were studied. They were selected from the Hepatology Clinic, Cairo University, and compared with seven children who happened to have incidental normal liver biopsy. The patients were divided into three groups: extrahepatic biliary atresia (n=13, neonatal hepatitis (n=15 and paucity of intrahepatic bile ducts (n=6; GPx, SOD and CAT levels were measured in fresh liver tissue using ELISA . Results: In the cholestatic patients, a significant increase was found in mean levels of SOD, GPx and CAT in hepatic tissue compared to control children. The three enzymes significantly increased in the extrahepatic biliary atresia group, whereas in the groups of neonatal hepatitis and paucity of intrahepatic bile ducts, only GPx and CAT enzymes were significantly increased. Conclusion: Oxidative stress could play a role in the pathogenesis of cholestatic chronic liver diseases. These preliminary results are encouraging to conduct more extensive clinical studies using adjuvant antioxidant therapy.

    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

    AIM: To investigate the current seroprevalence of hepatitis A virus (HAV) antibodies in patients with chronic viral liver disease in Korea. We also tried to identify the factors affecting the prevalence of HAV antibodies.METHODS: We performed an analysis of the clinical records of 986 patients (mean age: 49 ± 9 years, 714males/272 females) with chronic hepatitis B virus (HBV)or hepatitis C virus (HCV) infection who had undergone HAV antibody testing between January 2008 and December 2009.RESULTS: The overall prevalence of IgG anti-HAV was 86.61% (854/986) in patients with chronic liver disease and was 88.13% (869/986) in age- and gendermatched patients from the Center for Health Promotion.The anti-HAV prevalence was 80.04% (405/506)in patients with chronic hepatitis B, 86.96% (20/23)in patients with chronic hepatitis C, 93.78% (422/450)in patients with HBV related liver cirrhosis, and 100%(7/7) in patients with HCV related liver cirrhosis. The anti-HAV prevalence according to the decade of age was as follows: 20s (6.67%), 30s (50.86%), 40s (92.29%), 50s (97.77%), and 60s (100%). The anti-HAV prevalence was significantly higher in patients older than 40 years compared with that in patients younger than 40 years of age. Multivariable analysis showed that age ≥ 40 years, female gender and metropolitan cities as the place of residence were independent risk factors for IgG anti-HAV seropositivity.CONCLUSION: Most Korean patients with chronic liver disease and who are above 40 years of age have already been exposed to hepatitis A virus.

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

    Luís Henrique Bezerra Cavalcanti Sette

    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.

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.

    This study was undertaken to assess the frequency of development and the stages of evolution of chronic liver disease in patients with renal failure who are chronic carriers of hepatitis B surface antigen. Cirrhosis or chronic active hepatitis developed in five of 21 patients and could not be predicted by the initial histological appearance or by HLA-A and B typing but was associated with the e antigen in four of the five patients. However, the antigen was not a consistent indicator of a poor...

    AIM: To investigate the change of HBV DNA, PCNA and GST-π in chronic liver disease and hepatocellular carcinoma (HCC).METHODS: Hepatitis B surface antigen (HBsAg), proliferating cell nuclear antigen (PCNA) and glutathione S-transferases (GST-π) were detected by immunohistochemical staining and HBV DNA was detected by in situ hybridization (ISH) in formalin-fixed and paraffin-embedded sections with a total of 111 specimens of chronic hepatitis, liver cirrhosis,paratumorous tissue, HCC and normal liver tissue.RESULTS: The positive rates of HBsAg and HBVDNA were 62.5 %(15/24) and 75.0 %(12/16) in chronic hepatitis,64.0 %(16/25) and 83.3 %(15/18) in liver cirrhosis, 72.7 %(16/22) and 85.7 %(12/14) in the paratumorous tissu and 45.0 %(14/31) and 64.3 %(9/14) in HCC. The positive HBVDNA granules in chronic hepatitis, liver cirrhosis and the paratumorous tissue were more intense than that in HCC.The positive rates of PCNA and GST-π were 34.8 %(8/23)and 25.0 %(4/16) in chronic hepatitis, 73.7 %(14/19) and 17.6 %(3/17) in liver cirrhosis, 86.7 %(13/15) and 53.3 % (8/15) in the paratumorous tissue, 100 %(15/15) and 60.0 %(9/15) in HCC, respectively, and the positive rate of GST-πin the paratumorous tissue was significantly higher than that in the liver cirrhosis without tumor (P<0.05), but same as that in HCC(P>0.05).CONCLUSION: The HBV infection may increase expression of PCNA and GST-π. The paratumor cirrhosis may be a sequential lesion of precancerous cirrhosis around HCC.

    2014-07-01

    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

    Increasing evidence suggests that derangement of gut flora is of substantial clinical relevance to patients with cirrhosis. Intestinal bacterial overgrowth and increased bacterial translocation of gut flora from the intestinal lumen, in particular, predispose to an increased potential for bacterial infection in this group. Recent studies suggest that, in addition to their role in the pathogenesis of overt infective episodes and the clinical consequences of sepsis, gut flora contributes to the pro-inflammatory state of cirrhosis even in the absence of overt infection.Furthermore, manipulation of gut flora to augment the intestinal content of lactic acid-type bacteria at the expense of other gut flora species with more pathogenic potential may favourably influence liver function in cirrhotic patients. Here we review current concepts of the various inter-relationships between gut flora, bacterial translocation, bacterial infection, pro-inflammatory cytokine production and liver function in this group.

    Full Text Available Background: Chronic liver disease (CLD is a global medical problem. This disease is associated with increased hepatic oxidative stress. One of the antioxidant enzymes that protect cells against this stress is heme oxygenase-1 (HO-1.Objectives: This study aimed to investigate the mRNA expression of HO-1 in Egyptian patients with CLD and its relation to oxidative stress biomarkers.Patients and Methods: Levels of serum ferritin, carboxyhemoglobin, malondialdehyde (MDA, and erythrocyte-reduced glutathione (GSH were measured, and HO-1 mRNA expression was detected in 45 CLD patients (15 with nonalcoholic steatohepatitis [NASH], 15 with chronic hepatitis C, and 15 with liver cirrhosis and 15 healthy controls.Results: HO-1 mRNA expression was increased in patients with NASH, chronic hepatitis C, and liver cirrhosis compared to controls. The expression in cirrhotic patients was significantly higher than that in patients with NASH and chronic hepatitis C. Compared to controls, patients with NASH, chronic hepatitis C, and liver cirrhosis had higher levels of ferritin, carboxyhemoglobin, and MDA and lower levels of GSH. HO-1 mRNA expression was positively correlated with levels of carboxyhemoglobin, serum ferritin, and serum MDA and negatively correlated with levels of erythrocyte GSH in CLD patients.Conclusions: HO-1 mRNA expression was significantly increased in CLD patients, and the increase reflected the severity of the disease. The significant relationship between the increased HO-1 expression and oxidative stress biomarkers in patients with CLD suggests that HO-1 may play an important role in protecting the liver from oxidative stress-dependent damage. Therefore, induction of HO-1 could be a novel therapeutic option for CLD.

    AIM: To study the safety and efficacy of hepatitis A vaccine (HAV) in children with chronic liver disease of various etiologies.METHODS: Eleven children with chronic liver disease and thirteen age- and sex-matched controls negative for HAV antibodies were vaccinated against hepatitis A after they gave their informed consent. Children with uncontrolled coagulopathy or signs of hepatic decompensation were excluded. The vaccine (Havrix:720 ELISA units in 0.5 mL, from GlaxoSmithKline Biologicals) was given intramuscularly in the deltoid in 2 doses 6 mo apart. Children were tested for HAV antibodies one and six months after the 1st dose and one month after the 2nd dose. Total serum bilirubin, alanine aminotransferase (ALT), and aspartate aminotransferase (AST) were determined immediately before and after one month of the 1st dose of the vaccine.RESULTS: Only 7 out of the 11 patients were positive for HAV antibodies after the 1st dose of the vaccine,as compared to 100% of the controls. One month after the 2nd dose, all patients tested were positive for HAV antibodies. No deterioration in liver functions of patients was noted after vaccination. No adverse events,immediate or late, were reported by the mothers after each dose of the vaccine.CONCLUSION: Hepatitis A vaccine is both safe and effective in this small studied group of children with chronic liver disease. Given the high seroconversion rate, post-vaccination testing for HAV antibodies is not needed.

    Highlights: Black-Right-Pointing-Pointer The expression of the atypical cadherin FAT1 is increased in chronic liver disease. Black-Right-Pointing-Pointer FAT1 expression goes up during the activation of hepatic stellate cells (HSCs). Black-Right-Pointing-Pointer Activated HSCs are the cellular source of enhanced FAT1 expression in diseased livers. Black-Right-Pointing-Pointer FAT1 enhanced NFkB activity and resistance to apoptosis in activated HSCs. Black-Right-Pointing-Pointer 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

    Lipid peroxidation is an autocatalytic mechanism leading to oxidative destruction of cellular membranes. The deleterious consequences of this mechanism are related in part to the formation of reactive aldehydic products that bind to intra- or extracellular molecules to form adducts. Specific antibodies directed against malondialdehyde (MDA) and 4-hydroxynonenal (HNE) adducts, major aldehydic metabolites of lipid peroxidation, allowed us to investigate in situ, with an immunohistochemical procedure, the occurrence of lipid peroxidation in a panel of different chronic liver diseases. Intracellular HNE and MDA adducts were detected respectively in 24 of 39 cases (62%) and in 12 of 34 cases investigated (35%). They were localized mainly in the cytoplasm of hepatocytes, with the strongest staining observed in hemochromatosis, Wilson's disease, and in areas of acute alcoholic hepatitis in cases of alcoholic liver diseases. A peculiar pattern of immunostaining was observed in primary biliary cirrhosis where biliary cells of destroyed but also intact bile ducts strongly expressed HNE adducts. The liver extracellular matrix also displayed MDA adducts (30 of 34 cases, 88%) and HNE adducts (23 of 39 cases, 59%). While HNE adducts were specifically localized on large bundles of collagen fibers, MDA adducts were detected in a thin reticular network and in sinusoidal cells around portal tracts or fibrous septa. In conclusion, lipid peroxidation by-products are detectable in chronic liver diseases. Immunohistochemical results suggest that this mechanism is implicated very early in the pathogenesis of some of these diseases.

    Regarding limited effectiveness of many hepatic medical approaches, seeking for novel treatment strategies is crucial to improve outcomes. Hence, the current study aims to compile a concise but critical review over reported liver diseases and related medicinal plants from the Persian medicine perspectives. To this end, five main pharmaceutical manuscripts of Persian medicine from 9th-18th A.D. as well as the latest and largest medical textbook of Persian medicine were studied. By searching through databases such as PubMed and ScienceDirect, mechanisms or pharmacological activities of reported medicinal plants in the field of liver diseases were cited and discussed. In all, seventeen different liver diseases, mainly chronic, were cited in Persian medicine. Ninety three medicinal plants with liver tonic, hepatoprotective and related effectiveness belonging to 49 families were derived and authenticated from these studied manuscripts. More than 75% of the herbs showed related hepatoprotectivity and antioxidant activities. However, none of them have been examined clinically. Besides historical clarification, the current investigation compiled an evidence- based study on reported liver herbal remedies from the standpoints of Persian scholars. Conducting attributable clinical trials against the backdrops of proven in vitro and in vivo studies may result in new treatment discoveries for liver diseases.

    AIM: To determine the complex of AST and immunoglobulin and to investigate its clinical significance in patients with liver disease.METHODS: The complex of AST and immunoglobulin was determined by encounter immunoelectrophoresis and its clinical significance was investigated in 128 patients with liver disease.RESULTS: AST was bound to immunoglobulin of antiimmunoglobulin A (IgA) class, but any binding to antiimmunoglobulin G and anti-immunoglobulin M classes was not observed. Although the incidence of ASTimmunoglobulin complex was 41.8% in chronic hepatitis (CH), the incidences in liver cirrhosis and hepatocellular carcinoma were 62.2 and 90.0%, respectively. In alcoholic liver disease with high level of serum IgA, the incidence of the complex was 66.7%, which was higher than that in CH. The ratio of binding to lambda-chain of IgA was higher than that to kappa-chain of IgA. The serum level of IgA and the ratio of AST/alanine aminotransferase (ALT) were significantly higher in patients with AST-IgA complex than in those without complex.CONCLUSION: These results suggest that AST-IgA complex in patients with progressive liver diseases and alcoholic liver injury can lead to elevation of the ratio of AST/ALT.

    Transient elastography is a recently developed noninvasive technique for the assessment of hepatic fibrosis.The technique has been subject to rigorous evaluation in a number of studies in patients with chronic liver disease of varying aetiology. Transient elastography has been compared with histological assessment of percutaneous liver biopsy, with high sensitivity and specificity for the diagnosis of cirrhosis, and has also been used to assess pre-cirrhotic disease. However, the cut-off values between different histological stages vary substantially in different studies, patient groups and aetiology of liver disease. More recent studies have examined the possible place of transient elastography in clinical practice, including risk stratification for the development of complications of cirrhosis. This review describes the technique of transient elastography and discusses the interpretation of recent studies, emphasizing its applicability in the clinical setting.

    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%.

    AIM: To evaluate serum neopterin levels and their correlations with liver function tests and histological grade in children with hepatitis-B-related chronic liver disease.METHODS: The study population comprised 48 patients with chronic active hepatitis B, 32 patients with hepatitis-B-related active liver cirrhosis and 40 normal controls. Serum neopterin was measured using an enzyme-linked irnmunosorbent assay.RESULTS: The mean ±SD serum neopterin levels were 14.2±5.6 nmol/L in patients with chronic hepatitis, 20.3±7.9 nmol/L in patients with liver cirrhosis and 5.2±1.4 nmol/L in control group. Serum neopterin levels were significantly higher in patients with chronic hepatitis (P = 0.005) and cirrhosis patients (P =0.008), than in control subjects. Cirrhotic patients had significantly higher serum neopterin levels than patients with chronic hepatitis (P=0.004). There was a positive correlation between serum neopterin levels and alanine aminotransferase levels in patients with chronic hepatitis (r = 0.41, P = 0.004) and cirrhotic patients (r = 0.39, P = 0.005). Positive correlations were detected between serum neopterin levels and inflammatory score in patients with chronic hepatitis (r = 0.51, P = 0.003) and cirrhotic patients (r = 0.49, P = 0.001).CONCLUSION: Our results suggest that serum neopterin levels can be considered as a marker of inflammatory activity and severity of disease in children with hepatitis-B-related chronic liver disease.

    Various types of virus induced and non-virus induced chronic active hepatitis (CAH) as well as chronic non-suppurative destructive cholangitis (PBC) and primary sclerosing cholangitis have to be distinguished. Classical autoimmune type "lupoid" CAH is characterized by antinuclear antibodies (ANA), liver membrane antibodies (LMA) and smooth muscle antibodies (SMA). A second subgroup of autoimmune type CAH is characterized by anti liver kidney-microsomal antibodies (LKM) which are directed against a specific cytochrome p-450 isoenzyme. A third subgroup of autoimmune type CAH is identified by auto-antibodies to a soluble cytoplasmic liver antigen (SLA). Autoimmune type CAH profits from immuno-suppressive therapy, i.e. corticosteroids alone or in combination with azathioprin. Chronic hepatitis B virus infection is nowadays treated with Interferon when HBV-DNA is detectable in serum, duration of liver disease is less than 5 years and superinfection with HDV and HIV can be excluded. PBC is diagnosed through the detection of antimitochondrial antibodies (AMA) and its PBC specific subtypes anti p 62 (M2) and anti p 48. Aetiology and pathogenesis of PBC are still unknown. Liver transplantation is an established therapy for endstage PBC. This is also true for primary sclerosing cholangitis (PSC).

    Full Text Available ABSTRACT BACKGROUND AND OBJECTIVES: Assessing health-related quality of life is an important aspect of clinical practice. Thus, the present study attempts to assess the health-related quality of life of patients with chronic liver disease. METHODS: A cross-sectional survey was conducted on 133 chronic liver disease patients, using three instruments: a demographic questionnaire, the Chronic Liver Disease Questionnaire, and Model for End-Stage Liver Disease index. Variables were expressed as frequencies, percentages, means, and standard deviations. The statistical analysis included Pearson's correlation, Student's t-test, and analysis of variance (p < 0.05 was considered significant. RESULTS: The mean age of included subjects was 50.5 ± 13.3 years. The majority were male (66.2%, Caucasian (70.7%, and had a family income of US$329-US$658.2. Over half of the patients (56.4% were infected by hepatitis C virus and 93.2% had low Model for End-Stage Liver Disease scores. Model for End-Stage Liver Disease score was related to age (r = 0.185;p = 0.033. Higher mean Chronic Liver Disease Questionnaire scores were obtained for emotional function (39.70/SD ± 12.98 and while lower scores were obtained for abdominal symptoms (16.00/SD ± 6.25. Fifty-two patients (39.1% presented overall low (<5 Chronic Liver Disease Questionnaire scores. Furthermore, Chronic Liver Disease Questionnaire score was related to family income (r = 0.187, p = 0.031. CONCLUSION: Most individuals presented high mean Chronic Liver Disease Questionnaire scores, indicating low health-related quality of life, especially individuals with low family income.

    Liver diseases in pregnancy may be categorized into liver disorders that occur only in the setting of pregnancy and liver diseases that occur coincidentally with pregnancy. Hyperemesis gravidarum, preeclampsia/eclampsia, syndrome of hemolysis, elevated liver tests and low platelets (HELLP), acute fatty liver of pregnancy, and intrahepatic cholestasis of pregnancy are pregnancy-specific disorders that may cause elevations in liver tests and hepatic dysfunction. Chronic liver diseases, including cholestatic liver disease, autoimmune hepatitis, Wilson disease, and viral hepatitis may also be seen in pregnancy. Management of liver disease in pregnancy requires collaboration between obstetricians and gastroenterologists/hepatologists. Treatment of pregnancy-specific liver disorders usually involves delivery of the fetus and supportive care, whereas management of chronic liver disease in pregnancy is directed toward optimizing control of the liver disorder. Cirrhosis in the setting of pregnancy is less commonly observed but offers unique challenges for patients and practitioners. This article reviews the epidemiology, pathophysiology, diagnosis, and management of liver diseases seen in pregnancy.

    Because Mongolia has much higher liver disease burden than any other regions of the world, it is necessary to provide information on real-time situation of chronic liver disease in Mongolia. In this article, we reviewed studies performed in Mongolia from 2000 to 2011 on seroprevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) among healthy individuals and patients with chronic liver diseases, and on the practice patterns for the management of liver cirrhosis and hepatocellular carcinoma (HCC). According to previous reports, the seroprevalence of HBV and HCV in general population in Mongolia is very high (11.8% and 15% for HBV and HCV, respectively). Liver cirrhosis is also highly prevalent, and mortality from liver cirrhosis remained high for the past decade (about 30 deaths per 100,000 populations per year). Among patients with cirrhosis, 40% and 39% are positive for HBsAg and anti-HCV, respectively, and 20% are positive for both. The seroprevalence is similar for HCC and more than 90% of HCC patients are positive for either HBV or HCV. The incidence of HCC in Mongolia is currently among the highest in the world. The mortality from HCC is also very high (52.2 deaths per 100,000 persons per year in 2010). Partly due to the lack of established surveillance systems, most cases of HCC are diagnosed at an advanced stage. The mortality from liver cirrhosis and HCC in Mongolia may be reduced by implementation of antiviral therapy program and control of alcohol consumption.

    Liver X receptor (LXR), a nuclear hormone receptor, is an essential regulator of immune responses. Activation of LXR-mediated transcription by synthetic agonists, such as T0901317 and GW3965, attenuates progression of inflammatory disease in animal models. However, the adverse effects of these conventional LXR agonists in elevating liver lipids have impeded exploitation of this intriguing mechanism for chronic therapy. Here, we explore the ability of a series of sterol-based LXR agonists to alleviate inflammatory conditions in mice without hepatotoxicity. We show that oral treatment with sterol-based LXR agonists in mice significantly reduces dextran sulfate sodium colitis-induced body weight loss, which is accompanied by reduced expression of inflammatory markers in the large intestine. The anti-inflammatory property of these agonists is recapitulated in vitro in mouse lamina propria mononuclear cells, human colonic epithelial cells, and human peripheral blood mononuclear cells. In addition, treatment with LXR agonists dramatically suppresses inflammatory cytokine expression in a model of traumatic brain injury. Importantly, in both disease models, the sterol-based agonists do not affect the liver, and the conventional agonist T0901317 results in significant liver lipid accumulation and injury. Overall, these results provide evidence for the development of sterol-based LXR agonists as novel therapeutics for chronic inflammatory diseases.-Yu, S., Li, S., Henke, A., Muse, E.

    Glucosamine and chondroitin sulfate are molecules involved in the formation of articular cartilage and are frequently used for symptom relief in patients with arthrosis. These molecules are well tolerated with scarce secondary effects. Very few cases of possible hepatotoxicity due to these substances have been described. The aim of this paper is to report the frequency of presumed glucosamine hepatotoxicity in patients with liver disease. A questionnaire was given to 151 consecutive patients with chronic liver disease of different etiology (mean age 59 years, 56.9% women) attended in an outpatient clinic with the aim of evaluating the frequency of consumption of these drugs and determine whether their use coincided with a worsening in liver function test results. Twenty-three patients (15.2%) recognized having taken products containing glucosamine or chondroitin sulfate previously or at the time of the questionnaire. Review of the clinical records and liver function tests identified 2 patients presenting an elevation in aminotransferase values temporarily associated with glucosamine treatment; one of the cases simultaneously presented a skin rash attributed to the drug. Review of these two patients and the cases described in the literature suggest toxicity of glucosamine and chondroitin sulfate. The clinical spectrum is variable, and the mechanism of toxicity is not clear but may involve reactions of hypersensitivity. The consumption of products containing glucosamine and/or chondroitin sulfate is frequent among patients with chronic liver diseases and should be taken into account on the appearance of alterations in liver function tests not explained by the underlying disease.

    AIM: To investigate the relationship between ferritin and steatosis in patients with chronically abnormal liver function tests (LFTs) and high ferritin level. METHODS: One hundred and twenty-four consecutive patients with hyperferritinemia (male > 300 ng/mL, female > 200 ng/mL) were evaluated; clinical, biochemical and serological data, iron status parameters, HFE gene mutations and homeostasis model assessment score were obtained. Steatosis was graded by ultrasound as absent or present. Histology was available in 53 patients only. RESULTS: Mean level of ferritin was 881 ± 77 ng/mL in men and 549 ± 82 ng/mL in women. The diagnosis was chronic hepatitis C in 53 (42.7%), non-alcoholic fatty liver disease/non-alcoholic steatohepatitis in 57 (45.9%), and cryptogenic liver damage in 14 (11.3%). None was diagnosed as hereditary hemochromatosis (HH). Hepatic siderosis on liver biopsy was present in 17 of 54 (32%) patients; grade 1 in eight and grade 2 in nine. Overall, 92 patients (74.2%) had steatosis. By logistic regression, ferritin and g-glutamyltransferase were independent predictors of steatosis. Ferritin levels were significantly related to low platelet count, steatosis and hepatitis C virus infection. CONCLUSION: In a non-obese cohort of non-alcoholic patients with chronically abnormal LFTs without HH, high serum ferritin level is a risk factor for steatosis.

    AIM: To evaluate transient elastography (TE) as a noninvasive tool in staging liver fibrosis compared with liver biopsy and morphometry in children with different chronic liver diseases. METHODS: A total of 90 children [50 with chronic hepatitis C virus (HCV), 20 with autoimmune hepatitis (AIH) and 20 with Wilson disease] were included in the study and underwent liver stiffness measurement (LSM) using TE. Liver biopsies were evaluated for fibrosis, qualitatively, by Ishak score and quantitatively by fibrosis area fraction (FAF) using digital image analysis (morphometry). LSM was correlated with fibrosis and other studied variables using spearman correlation. A stepwise multiple regression analysis was also performed to examine independent factors associated with LSM. Different cut-off values of LSM were calculated for predicting individual fibrosis stages using receiver-operating characteristic curve. Cut-off values with optimal clinical performance (optimal sensitivity and specificity simultaneously) were selected. RESULTS: The majority of HCV group had minimal activity (80%) and no/mild fibrosis (72%). On the other hand, the majority of AIH group had mild to moderate activity (70%) and moderate to severe fibrosis (95%) and all Wilson disease group had mild to moderate activity (100%) and moderate to severe fibrosis (100%). LSM correlated significantly with both FAF and Ishak scores and the correlation appeared better with the latter (r = 0.839 vs 0.879, P < 0.0001 for both). LSM discriminated individual stages of fibrosis with high performance. Sensitivity ranged from 81.4% to 100% and specificity ranged from 75.0% to 97.2%. When we compared LSM values for the same stage of fibrosis, they varied according to the different etiologies. Higher values were in AIH (16.15 ± 7.23 kPa) compared to Wilson disease (8.30 ± 0.84 kPa) and HCV groups (7.43 ± 1.73 kPa). Multiple regression analysis revealed that Ishak fibrosis stage was the only independent variable

    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.

    AIM: In the inflammatory state, intercellular adhesion molecule-1 (ICAM-1) and vascular cellular adhesion molecule-1 (VCAM-1) play a key role in promoting migration of immunological cells from the circulation to target site.Aim of our study was to investigate soluble forms of these molecules in patients with virus-related chronic liver diseases, to assess their behavior in different pathologies and correlation with severity of liver damage.METHODS: Circulating ICAM-1 and VCAM-1 were assayed by EIA commercial kits (R&D System Co.,Abington, UK) in 23 patients with chronic active hepatitis (CH), 50 subjects affected by liver cirrhosis (LC) and 15 healthy controls comparable for sex and age. In patients, serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were also detected by autoanalyzer.RESULTS: LC patients had significantly higher ICAM-1 values than CH patients (38.56±7.4 ng/mL vs 20.89±6.42 ng/mL; P<0.001) and these ones had significantly higher values than controls (12.92±1.08 ng/mL; P<0.001). In CH group, ICAM-1 levels were significantly related to inflammatory activity (P= 0.041) and ALT values (r= 0.77;P<0.05). VCAM-1 values were significantly increased only in LC patients (P<0.001) and related to severity of liver impairment.CONCLUSION: These findings suggest that the determination of serum ICAM-1 can be considered as an additional useful marker of hepatocellular necrosis and inflammatory activity in chronic hepatitis, while serum VCAM-1 is an indicator of liver fibrogenesis and severity of disease in cirrhosis.

    The total serum sialic acid concentration was determined in 2,264 persons with various malignant tumors, bacterial infections, rheumatic diseases, and chronic liver diseases, and in a control group. The thiobarbiturate method according to Warren was used. The upper limit (95% percentile) in the control group was 2.23 mumol/ml. Higher values were found in the groups with neoplasms (mean: 3.04 mumol/ml), inflammatory diseases (e.g., pneumonia: 3.02 mumol/ml), and active rheumatoid arthritis (3.05 mumol/ml). In the group with malignant diseases, the sialic acid concentration at the time of diagnosis was highest for bronchial carcinoma (3.29 mumol/ml) and lowest for breast cancer (2.58 mumol/ml). In chronic liver diseases the mean sialic acid level was lower than in a heterogeneous group of noninflammatory and nonneoplastic diseases. The estimation of the serum sialic acid concentration could be useful in the detection of tumor burden and metastases, and in the evaluation of the later course and prognosis of malignant neoplasms if bacterial/inflammatory and active rheumatoid processes can be excluded.

    Patients with end-stage liver disease often reveal significant protein-energy malnutrition, which may deteriorate after listing for transplantation. Since malnutrition affects post-transplant survival, precise assessment must be an integral part of pre- and post-surgical management. While there is wide agreement that aggressive treatment of nutritional deficiencies is required, strong scientific evidence supporting nutritional therapy is sparse. In practice, oral nutritional supplements are preferred over parenteral nutrition, but enteral tube feeding may be necessary to maintain adequate calorie intake. Protein restriction should be avoided and administration of branched-chain amino acids may help yield a sufficient protein supply. Specific problems such as micronutrient deficiency, fluid balance, cholestasis, encephalopathy, and comorbid conditions need attention in order to optimize patient outcome.

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

    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.

    It is well known that hepatocellular carcinoma (HCC) develops as a consequence of hepatic fibrosis progression. In this study, we aimed to evaluate the inflammatory and fibrosis markers as predictors for HCC development among patients with hepatitis C virus (HCV) related chronic liver disease to help in early diagnosis and management of HCC. A total of 280 patients with chronic liver disease were included in this retrospective study, out of them 140 had liver cirrhosis with HCC and 140 had cirrhosis without HCC. Eight readily available blood indices King score, Fibro Q, AST-ALT ratio (AAR), APRI, LOK index, Goteborg University Cirrhosis Index (GUCI), fibro alpha, and Biotechnology Research Center (BRC) were constructed to compare the accuracies of these non invasive scores in predicting HCC development. All fibrosis scores except APRI were significantly higher in HCC. We found that Fibro alpha and BRC had superior diagnostic performance in prediction of HCC based on area under curve of 0.91 and 0.93, respectively compared to other scores with area under curve ranged from poor to failure (0.59-0.66). Almost all cirrhotic cases were secondary to HCV (93.6%), while HBV was detected in 2.1% of cases only. Anti-HCV positive was reported in 100% of HCC cases (P = 0.002). Fibro alpha and BRC scores can be used for prediction of HCC. J. Med. Virol. © 2016 Wiley Periodicals, Inc.

    Fibrosis, a common pathogenic pathway of chronic liver disease (CLD), has long been indicated to be significantly and most importantly associated with severe prognosis. Nowadays, with remarkable advances in understanding and/or treatment of major CLDs such as hepatitis C, B, and nonalcoholic fatty liver disease, there is an unprecedented requirement for the diagnosis and assessment of liver fibrosis or cirrhosis in various clinical settings. Among the available approaches, liver biopsy remains the one which possibly provides the most direct and reliable information regarding fibrosis patterns and changes in the parenchyma at different clinical stages and with different etiologies. Thus, many endeavors have been undertaken for developing methodologies based on the strategy of quantitation for the invasive assessment. Here, we analyze the impact of fibrosis assessment on the CLD patient care based on the data of recent clinical studies. We discuss and update the current invasive tools regarding their technological features and potentials for the particular clinical applications. Furthermore, we propose the potential resolutions with application of quantitative invasive tools for some major issues in fibrosis assessment, which appear to be obstacles against the nowadays rapid progress in CLD medicine.

    Interferon (alpha-IFN) exerts a modulating effect on the immune system. Kupffer cells of the liver play an important immunological role by their uptake of various agents and particles, including colloids. We sought to discover if alpha-IFN could enhance the colloid uptake function of the Kupffer cells. The effect of alpha-IFN therapy on radioisotope scans of the liver was studied in 20 patients with chronic liver disease due to hepatitic C virus (HCV) infection who received therapy at a dose of 3 million IU for 6 mo, in another patients who received the same therapy for 12 mo and in matched control groups (10 patients with HCV infection for each study group) who did not received alpha-IFN. A {sup 99m}Tc-sulfur colloid scan of the liver was obtained for each group before and after therapy and, for control subjects, at the start and end of the study periods. The liver-to-spleen geometric mean ratio of colloid uptake was assessed. In the first study group, the mean rate of improvement in the liver-to-spleen ratio was 48% in 70% of the patients, compared to 8% in 20% of controls (p<0.05). In the second study group, mean liver-to-spleen ratio was 88% in 85% of patients, compared to 12% in 40% of controls (p<0.001). Alpha-IFN therapy appears to enhance the colloidal uptake function of Kupffer cells, which adds a new dimension to the immunomodulatory effect of interferon. 13 refs., 2 tabs.

    Patients who are chronically infected with the hepatitis C virus often develop chronic liver disease and assessment of the severity of liver injury is required prior to considering viral eradication therapy. This article examines the various assessment methods currently available from gold standard liver biopsy to serological markers and imaging. Ultrasound is one of the most widely used imaging modalities in clinical practice and is already a first-line diagnostic tool for liver disease. Microbubble ultrasound contrast agents allow higher resolution images to be obtained and functional assessments of microvascular change to be carried out. The role of these agents in quantifying the state of hepatic injury is discussed as a viable method of determining the stage and grade of liver disease in patients with hepatitis C. Although currently confined to specialist centres, the availability of microbubble contrast-enhanced ultrasound will inevitably increase in the clinical setting.

    Full Text Available Objective: Hepatitis B is an important infectious disease,which can cause severe chronic cirrhosis and hepatocellularcarcinoma in 1-5 % of adult patients. Whereas, HepatitisD is a defective virus infection that develops in people withHBsAg (+. It has been known that Hepatitis D virus has acytopathic effect but the immune mechanisms which play arole in the development of this disease are still under investigation.Therefore, in this study it was aimed to investigatewhether lymphocytes numbers change in a variety of patientswith chronic hepatitis.Methods: In this study, 22 patients (12 females and 10males with chronic liver diseases were examined. Thesepatients were compared to the control group which consistsof 20 healthy individuals (12 females, 8 males. A flowcytometry assay was conducted to examine T lymphocytesubgroups using CD3, CD4, CD8, CD25, CD56, CD161 andVα24 monoclonal antibodies in peripheral blood samples ofboth patient and control groups.Results: The mean age of patient group and control groupwere 45.87±11.18 and 41.45±7.23 year respectively. TheHbsAg was found to be positive in all patients with the exceptionof one patient. 15 patients also exhibited Anti DeltaAntigen positive as well as HbsAg. Six of these patientshave been diagnosed with chronic liver disease, 7 of themhave been diagnosed liver chrosis and two of them havebeen diagnosed with hepathoma. No difference was foundbetween the patients and healthy controls in terms of totalT lymphocyte, CD4+Th cells CD3+CD56+ NKT cells andVα24+CD161+ iNKT cells. However, the levels of CD8+ Tccells, CD16+56+ NK cells and CD4+CD25+ T lymphocyteswere found to be lower in patients bloods as compared tothe healthy controls.Conclusions: These results suggest that HbsAg positivitymay cause the decreases of the cells which are responsiblefor cytotoxic response. Nevertheless, further studiesare required to explain the immunological response to thechronic hepatitis.Key words: Chronic hepatitis

    AIM: To investigate the association between serum insulin-like growth factor 1 (IGF-1), osteocalcin, and parathyroid hormone (PTH) levels with the etiology and clinical condition of patients with chronic liver disease.METHODS: Eighty children with hepatocellular damage were divided into 3 groups according to the etiology of disease infection: bilharziasis (9 patients), hepatitis B virus (HBV, 12 patients) and hepatitis C virus (HCV, 29 patients). The Child score index was found as A in 24 patients, B in 22 patients, C in 4 patients. Thirty healthy children served as control group. HBsAg, HBcAbIgM,HBcAbIgG, and anti-HCV were detected using ELISA technique. HCV-RNA was measured by reverse transcription polymerase chain reaction (RT-PCR). Antibilharzial antibodies were detected by indirect haemagglutination test. Liver function tests were performed using autoanalyser. Serum IGF-1, osteocalcin and PTH levels were measured by ELISA technique. Abdominal ultrasonography was also conducted.RESULTS: Serum IGF-1 level was significantly lower in all patient groups with liver diseases, while serum osteocalcin and PTH levels were significantly elevated in patients with HBV and HCV infections compared with the control group. Serum osteocalcin and PTH concentrations were measured with the severity of liver disease from Child A to C. Child A patients unexpectedly showed significantly reduced IGF-1 levels in comparison to patients staged as Child B or C. Serum osteocalcin level was negatively correlated with albumin (14.7 ± 0.54 vs 3.6± 0.10, P < 0.05), while that for PTH was positively correlated with total protein (70.1 ± 2.17 vs 6.7 + 0.10,P < 0.05) in patients with HCV infection.CONCLUSION: Low serum IGF-1 level seems to play a critical role in the bone loss in patients with chronic liver disease. Elevated biochemical markers of bone remodeling suggest high-turnover in patients with viral infection and reflect severity of the clinical stage.

    To improve our knowledge for future hepatitis A virus (HAV) vaccination strategies we carried out a multicentre study on naturally acquired immunological protection against HAV in patients with chronic hepatitis in Italy. We enrolled 830 consecutive patients with chronic hepatitis on their first observation at one of the six Italian liver units participating in the study. Six hundred and fifty-eight patients (79.3%) were positive for total anti-HAV and 172 (20.7%) were negative. The anti-HAV negative patients were younger (median age 33, range 11-78) than the anti-HAV positive (median age 56, 18-87). There was a higher prevalence of cases with circulating anti-HAV among the 508 patients residing in southern Italy than in the 322 residing in northern Italy (88.8% vs. 64%, P immunological protection against HAV infection. The data suggest that the number of patients with chronic liver disease without naturally acquired immunity against HAV is substantial in Italy, particularly in the north of the country, and that new vaccination strategies are needed.

    Full Text Available Abstract Background Bax inhibitor-1 (BI-1 is an evolutionary conserved endoplasmic reticulum protein that, when overexpressed in mammalian cells, suppresses the apoptosis induced by Bax, a pro-apoptotic member of the Bcl-2 family. The aims of this study were: (1 to clarify the role of intrinsic anti- and pro-apoptotic mediators, evaluating Bax and BI-1 mRNA and protein expressions in liver tissues from patients with different degrees of liver damage; (2 to determine whether HCV and HBV infections modulate said expression. Methods We examined 62 patients: 39 with chronic hepatitis (CH (31 HCV-related and 8 HBV-related; 7 with cirrhosis (6 HCV-related and 1 HBV-related; 13 with hepatocellular carcinoma (HCC [7 in viral cirrhosis (6 HCV- and 1 HBV-related, 6 in non-viral cirrhosis]; and 3 controls. Bax and BI-1 mRNAs were quantified by real-time PCR, and BI-1 protein expression by Western blot. Results CH tissues expressed significantly higher BI-1 mRNA levels than cirrhotic tissues surrounding HCC (P Conclusions BI-1 expression is down-regulated as liver damage progresses. The high BI-1 mRNAs levels observed in early liver disease may protect virus-infected cells against apoptosis, while their progressive downregulation may facilitate hepatocellular carcinogenesis. HCV genotype seems to have a relevant role in Bax transcript expression.

Results Beclin 1 mRNA levels were lower in HCC than in CH (P = 0.010 or CIRR (P = 0.011, and so were the Bcl-xL transcripts (P  Conclusions High Beclin 1, Bcl-xL and Bad levels in CH and CIRR tissues suggest an interaction between autophagy and apoptosis in the early and intermediate stages of viral hepatitis. In HCC these processes seem to be downregulated, probably enabling the survival and growth of neoplastic hepatocytes.

    Permanent alcohol abuse may lead to chronic liver injury with deleterious sequelae such as liver cirrhosis and hepatocellular carcinoma. Mechanisms of fibrogenesis encompass recruitment of inflammatory cells at the site of injury and cytokine mediated activation of hepatic stellate cells (HSC) with accumulation of interstitial collagens. HSC transdifferentiation and accompanying apoptosis result in destruction of liver architecture and are therefore key steps of disease progression. TGF-beta represents the main profibrogenic cytokine in liver fibrosis and other fibroproliferative disorders by inducing extracellular matrix deposition as part of the wound healing response. In parallel, TGF-beta triggers hepatocytes that are strongly responsive for this cytokine, to undergo apoptosis, thereby providing space for HSC proliferation and generation of a collagenous matrix. Anti TGF-beta approaches were established and successfully utilized for the treatment of experimental fibrogenesis. Dominant negative TGF-beta receptors (TbetaR), generated by fusing the Fc domain of human IgG and the N-terminal (extracellular) fragment of TbetaRII (Fc:TbetaRII) were applied to suppress fibrosis. Similarly TGF-beta binding proteins like decorin, antagonistic cytokines such as bone morphogenetic protein-7, hepatocyte growth factor, IL-10, or IFN-gamma were as efficient as camostat mesilate, a protease inhibitor that possibly abrogated proteolytic activation of TGF-beta. Further, our group recently overexpressed Smad7 in bile duct ligation induced liver fibrosis and achieved efficient inhibition of intracellular TGF-beta signaling, thereby counteracting profibrogenic effects in cultured HSC and in vivo. A direct link between the effect of alcohol and TGF-beta exists through reactive oxygen species that are generated in liver cells by alcohol metabolism and represent activators of TGF-beta signaling. Thus, soluble TbetaRII expression reduced experimental fibrogenesis in vitro and in vivo

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

    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

    AIM: To study the Hepatitis B virus (HBV) genotypes and their effect on the progression and outcome in patients with chronic liver diseases from New Delhi, India.METHODS: Sera from 100 HBV-related chronic liver disease (CLDB) cases were tested for HBV genotype using Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) and Type-specific primers-based PCR (TSP-PCR) targeting to the surface (S)gene encoding hepatitis B surface antigen.RESULTS: Only genotypes A and D were present and genotype D was dominant. Genotype D was present in all CLDB patient categories. The genotype distribution for the 100 patients with CLDB was as follows: genotype A, 16/100 (16%) (7/40- 17% chronic hepatitis B (CHB);8/47, 17%, HBV-related cirrhosis (CRB); 1/13, 7.6%,HBV-related hepatocellular carcinoma (HCCB); genotype D- 84/100 (84%) (32/40- 80% CHB; 38/47- 81%, CRB;11/13, 85%, HCCB); genotype A + D, 3/100 (3%) (1/40-3% CHB; 1/47- 2%, CRB; 1/13, 7.6%, HCCB); C, 0; B, 0;E, 0; F, 0; G 0, H 0; (P < 0.01, genotype D vs A).CONCLUSION: Only HBV genotypes A and D were present in patients with CLDB from New Delhi, India.Compared with genotype D, genotype A patients had no significant clinical or biochemical differences (P > 0.05).Mixed infection with genotype A and D were seen in 3%of the cases. Genotype D was the dominant genotype prevalent in all patient categories.

  20. Chronic Kidney Disease and Nonalcoholic Fatty Liver Disease—Is There a Link?

    Full Text Available Research in recent years has led to the recognition of the importance of nonalcoholic fatty liver disease (NAFLD and its relationship to the metabolic syndrome (MS. This has led to a growing interest in the potential prognostic value of NAFLD for adverse cardiovascular disease (CVD outcome. On the other hand, searching for new risk factors for chronic kidney disease (CKD development and progression is very important. Growing evidence suggests that the MS is an important factor in the pathogenesis of CKD. The best confirmation of this pathogenic link is hypertensive and diabetic nephropathy as the main causes of CKD. Furthermore, the possible link between NAFLD and CKD has also attracted research interest and recent data suggest an association between these two conditions. These findings have fuelled concerns that NAFLD may be a new and added risk factor for the development and progression of CKD. NAFLD and CKD share some important cardiometabolic risk factors and possible common pathophysiological mechanisms, and both are linked to an increased risk of incident CVD events. Therefore, common factors underlying the pathogenesis of NAFLD and CKD may be insulin resistance, oxidative stress, activation of rennin-angiotensin system, and inappropriate secretion of inflammatory cytokines by steatotic and inflamed liver.

    Recent studies suggest the impact of apoptosis on the mechanisms leading to hypercoagulability. We aimed to clarify the potential role of neutrophil apoptosis in neutropenia and hypercoagulable state encountered in chronic liver disease patients. This study was conducted on 15 normal controls and 45 patients with chronic liver disease classified according to modified Child Pugh classification into, Child A, B and C groups (15 cases each). Haemostatic parameters studied include, prothrombin time, partial thromboplastin time, tissue factor, protein C antigen, protein S antigen, and markers of haemostatic activation [prothrombin fragment 1+2 (F1+2), thrombus precursor protein (TpP) and D-dimer]. Flowcytometric study was done for quantitative assay of neutrophil apoptotic subpopulations to detect the percentage of early and late apoptotic, and necrotic neutrophils using Annexin V-FITC/propidium iodide dye. Semiquantitative assay of apoptotic neutrophils showing DNA fragmentation was performed on neutrophil culture using terminal deoxynucleotidyl transferase mediated deoxyuridine triphosphate nick end labelling test. In addition to enzyme-linked immunosorbent assay for soluble Fas (APO-1/CD95) in culture supernatant. The results revealed a rise in the neutrophil apoptotic and necrotic markers with progression of the disease, and they were inversely correlated with the absolute neutrophil count. The apoptotic neutrophil cells showed a significant positive correlation with several haemostatic parameters (tissue factor, prothrombin fragment 1+2, thrombus precursor protein and D-dimer). Regression analysis proved that apoptotic parameters are independent determinants of prothrombotic markers, which further incriminate the apoptotic mechanisms in the hypercoagulable state encountered in this clinical setting.

    Patients with hepatic disorders are exceptionally vulnerable to developing malnutrition because of the key role played by the liver in regulating the nutritional state and the energy balance. Moreover, the presence of chronic liver disorders could reduce the appetite and thus influence the nutrient intake. Poor nutritional status has been shown in various patient groups with hepatic disorders, and particularly in patients with alcoholic cirrhosis who are at high nutritional risk. It is well established that malnourished patients with liver diseases generally have a higher risk of developing adverse clinical outcomes and increased healthcare costs. Nutrition screening with the Subjective Global Assessment and anthropometric measurements are an important first step in the early identification of malnutrition and initiates the whole nutrition care process. It is therefore important for appropriate nutrition policies and protocols to be implemented so that all patients with chronic liver diseases are monitored closely from a nutritional standpoint. Early and evidence-based nutritional interventions are eagerly needed to minimize the nutritional decline associated with chronic liver disorders and ultimately improve the prognosis of such patients. This review includes a comprehensive analysis of methods to identify malnutrition in patients with chronic liver diseases as well as the extent and impact of the malnutrition problem in selected patient populations.

    AIM: To determine the prevalences of TTV and HGV infections among blood donors and patients with chronic liver disease in Korea, to investigate the association of TTV and HGV infections with blood transfusion, and to assess the correlation between TTV and HGV viremia and hepatic damage.METHODS: A total of 391 serum samples were examined in this study. Samples were obtained from healthy blood donors (n= 110), hepatitis B surface antigen (HBsAg)-positive donors (n=112), anti-hepatitis C virus (anti-HCV)-positive donors (n=69), patients with type B chronic liver disease (n=81), and patients with type C chronic liver disease (n= 19).TTV DNA was detected using the hemi-nested PCR. HGV RNA was tested using RT-PCR. A history of blood transfusion and serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were also determined.RESULTS: TTV DNA was detected in 8.2 % of healthy blood donors, 16.1% of HBsAg-positive donors, 20.3 % of antiHCV-positive donors, 21.0 % of patients with type B chronic liver disease, and 21.1% of patients with type C chronic liver disease. HGV RNA was detected in 1.8 % of healthy blood donors, 1.8 % of HBsAg-positive donors, 17.4 % of anti-HCV-positive donors, 13.6% of patients with type B chronic liver disease, and 10.5% of patients with type C chronic liver disease. The prevalence of TTV and HGV infections in HBV- or HCV-positive donors and patients was significantly higher than in healthy blood donors (P<0.05),except for the detection rate of HGV in HBsAg-positive donors which was the same as for healthy donors. There was a history of transfusion in 66.7% of TTV DNA-positive patients and 76.9% of HGV RNA-positive patients (P<0.05). No significant increase in serum ALT and AST was detected in the TTV- or HGV-positive donors and patients.CONCLUSION: TTV and HGV infections are more frequently found in donors and patients infected with HBV or HCV than in healthy blood donors. However, there is no significant

    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 pathophysiological mechanisms of

    Full Text Available The pattern of liver diseases has radically changed in our country over the last few decades. We prospectively collected data on the newly-diagnosed cases of chronic liver diseases in a region of southern Italy after about a decade from the last epidemiological study. We conducted a multicentric prospective study that enrolled 631 patients from 21 Liver Centers of the Campania region (Southern Italy at their first hospital admission or at their first outpatient visit. In our cohort of 631 patients (367 males, 263 females, 397 (62.9% were hepatitis C virus (HCV positive, 75 (11.9% were hepatitis B virus (HBV positive, 8 (1.3% were co-infected by HBV and HCV, 73 (11.6% had an alcoholic liver disease and 64 (10.1% had a nonalcoholic fatty liver disease. HBV infection was present in young people with a higher-than-expected prevalence, despite the vaccination program which should have involved this population. HCV chronic hepatitis still remains the most common cause of liver disease in our region. HBV infection still continues to represent a health problem in young people, despite the vaccination program.

    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 < 0.05). It is important to recognize the difference between NAFLD and CHC. We concluded that changes in hepatic blood flow occurred during the earliest stage of hepatic fibrosis in patients with NAFLD; therefore, patients with NAFLD need to be followed carefully.

    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

    AIM: To study the expression of interferon-alpha/beta (IFN-α/β) receptor protein in liver of patients with hepatitis C virus (HCV)-related chronic liver disease and its clinical significance.METHODS: A total of 181 patients with HCV-related chronic liver disease included 56 with HCV-related liver cirrhosis (LC) and 125 with chronic hepatitis C (CHC).CHC patients were treated with five megaunits of interferon-α1b six times weekly for the first 2 weeks and then every other day for 22 wk. The patients were divided into interferon (IFN) treatment-responsive and nonresponsive groups, but 36 patients lost follow-up shortly after receiving the treatment. The expression of IFN-α/β receptor (IFN-α/βR) protein in liver of all patients was determined with immunofluorescence.RESULTS: In liver of patients with HCV-related chronic liver disease, the expression of IFN-α/βR protein in liver cell membrane was stronger than that in cytoplasm and more obvious in the surroundings of portal vein than in the surroundings of central vein. Moreover, it was poorly distributed in hepatic Iobules. The weak positive, positive and strong positive expression of IFN-α/βR were 40% (50/125), 28% (35/125), 32% (40/125), respectively in CHC group, and 91.1% (51/56), 5.35% (3/56), and 3.56% (2/56), respectively in LC group. The positive and strong positive rates were higher in CHC group than in LC group (P<0.01). In IFN treatment responsive group, 27.8% (10/36) showed weak positive expression; 72.2% (26/36)showed positive or strong positive expression. In the nonresponsive group, 71.7% (38/53) showed weak positive expression; 28.3% (15/53) showed positive or strong positive expression. The expression of IFN-α/βR protein in liver was more obvious in IFN treatment responsive group than in non-responsive group.CONCLUSION: Expression of IFN-α/βR protein in liver of patients with HCV-related chronic liver disease is likely involved in the response to IFN treatment.

    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) SF36Health Survey Version 2 (SF36v2).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 testretestreliabilities ranged from 0.580.90fordifferent subscales. Construct validity was confirmed by the expected correlations between the SF36v2 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.

    Full Text Available Aim. To investigate the factors contributing to health-related quality of life (HRQOL in Chinese patients with chronic liver disease (CLD. Methods. HRQOL was measured with SF-36v2 Chinese version. Demographic and clinical data were collected, and patients with liver cirrhosis were divided into Child’s Class A, B, and C according to Child-Turcotte-Pugh scoring system. Results. A total of 392 Chinese patients with CLD and 91 healthy controls were enrolled. HRQOL in patients with CLD was lower than that in healthy controls. Score of PCS in healthy controls was 54.6±5.5 and in CLD was 47.8±8.8 (P=0.000. Score of MCS in healthy controls was 56.4±8.1 and in CLD was 51.7±7.4 (P=0.000. Increasing severity of CLD from no cirrhosis to advanced cirrhosis was associated with a decrease on all domains of the SF-36 (P<0.05. Stepwise linear regression analysis showed that severity of disease, age, present ascites, present varices, and prothrombin time had significant effect on physical health area. Severity of disease, female, present varices, total bilirubin, prothrombin time, and hemoglobin had significant effect on mental health area. Conclusions. Patients with CLD had impaired HRQOL. Increasing severity of CLD was associated with a decrease on HRQOL. Old age, female gender, advanced stage of CLD, present ascites, hyperbilirubinemia, and prolonging prothrombin time were important factors reducing HRQOL.

    营养不良在肝病患者中很常见,其严重程度直接关系到患者的短期生存率,营养支持作为治疗慢性肝病的重要手段,对于慢性肝病患者的长期治疗与恢复非常必要.评价慢性肝病患者营养状态有多种方法,包括直接人体测量法、生化指标检测、免疫学指标、营养评定工具、人体组成测定等,各有优缺点,可从不同侧面综合评价营养状况.在进行营养支持时,应结合肝病的具体情况与患者的耐受能力,选择合适的营养物质与营养途径.%Malnutrition is common among patients with liver disease, and its severity directly influences the short-term survival. As an important approach for chronic liver disease, nutritional support is especially necessary for long-term rehabilitation and treatment. Many methods (e. g. direct human body measurement, biochemical indicator determination, immunological indicators, nutrition assessment tools, and human composition determination) can be applied for the nutritional status evaluation. Based on the specific disease condition and the patient's tolerance, nutritional supports (with proper nutritional substances and administrative route) should be provided individually.

    AIM: To investigate the serum erythropoietin (Epo) levels in patients with chronic liver diseases and to compare to subjects with iron-deficiency anaemia and healthy controls.METHODS: We examined 31 anaemic (ALC) and 22 nonanaemic (NALC) cirrhotic patients, 21 non- anaemic subjects with chronic active hepatitis (CAH), 24 patients with irondeficiency anaemia (ID) and 15 healthy controls. Circulating UK) and haemoglobin (Hb) concentration were determined in all subjects.RESULTS: Mean±SD of Epo values was 26.9±10.8 mU/mL in ALC patients, 12.5±8.0 mU/mL in NALC subjects,11.6±6.3 mU/mL in CAH patients, 56.4±12.7 mU/mL in the cases of ID and 9.3±2.6 mU/mL in controls. No significant difference (P>0.05) was found in Epo levels between controls, CAH and NALC patients. ALC individuals had higher Epo levels (P<0.01) than these groups whereas ID subjects had even higher levels (P<0.001) than patients suffering from ALC.CONCLUSION: Increased Epo values in cirrhotics, are only detectable when haemoglobin was lesser than 12 g/dL.Nevertheless, this rise in value is lower than that observed in anaemic patients with iron-deficiency and appears blunted and inadequate in comparison to the degree of anaemia.

    AIMS--To evaluate whether high numbers of silver staining nucleolar organiser regions (AgNORs) in hepatocytes are associated with increased risk of hepatocellular carcinoma in chronic liver disease. METHODS--The quantitative distribution of AgNORs was studied in the liver biopsy specimens of 33 patients with chronic liver disease, 11 of whom developed hepatocellular carcinoma. The interval between liver biopsy and diagnosis of hepatocellular carcinoma was 26 months (range one to 61 months); the mean follow up of patients without hepatocellular carcinoma was 45 months (range 24-59 months). Quantitative evaluation of AgNORs was carried out on silver stained routine sections by morphometric analysis, using a computer assisted image analysis system. RESULTS--High interphase AgNOR values (> 3 microns2) were found in hepatocytes of nine out of the 11 (82%) patients in whom neoplastic transformation occurred. Of the remaining 22 patients, only seven (31%) had AgNOR values higher than > 3 microns2 (chi 2 4.83; p = 0.036). CONCLUSIONS--These results indicate that high numbers of interphase AgNORs are associated with increased risk of hepatocellular carcinoma in patients with chronic liver disease. Images PMID:8408696

    AIM To assess the etiology of chronic liver diseases (CLD) from 1998 to 2014 at the outpatient clinic of Gastroenterology of the main hospital in Northwest of Italy among those dedicated to hepatology. METHODS A random sample of charts of patients referred to for increased liver enzymes between January 1998 and December 2006, and between January 2012 and December 2014 were reviewed. Etiology search included testing for hepatitis B virus (HBV), hepatitis C virus (HCV), autoimmune hepatitis, primary biliary cirrhosis, Wilson’s disease and hereditary hemocromatosis. A risky alcohol consumption was also considered. Non-alcoholic fatty liver disease (NAFLD) was diagnosed in patients with histological and/or ultrasound evidence of steatosis/steatohepatitis, and without other causes of CLD. RESULTS The number of patients included was 1163. Of them, 528 (45%) had positivity for HCV and 85 (7%) for HBV. Among the virus-free patients, 417 (36%) had metabolic disorders whereas the remaining had history of alcohol abuse, less prevalent causes of CLD or concomitant conditions. In comparison to 1998-2000 (41%), a reduction of HCV alone-related cases was detected during the periods 2001-2003 (35%, OR = 0.75, 95%CI: 0.53-1.06), 2004-2006 (33%, OR = 0.70, 95%CI: 0.50-0.97) and 2012-2014 (31%, OR = 0.64, 95%CI: 0.46-0.91). On the contrary, in comparison to 1998-2000 (31%), metabolic-alone disorders increased in the period 2004-2006 (39%, OR = 1.37, 95%CI: 0.99-1.91) and 2012-2014 (41%, OR = 1.53, 95%CI: 1.09-2.16). The other etiologies remained stable. The increase of incidence of metabolic-alone etiology during the period 2004-2006 and 2012-2014 tended to be higher in older patients (≥ 50 years) compared to younger (P = 0.058). CONCLUSION In the Northwest of Italy, during this study period, the prevalence of HCV infection decreased notably whereas that of NAFLD increased. PMID:27688660

    Chronic kidney disease (CKD) is a risk factor for end-stage renal disease (ESRD) and cardiovascular disease (CVD). ESRD or CVD develop in a substantial proportion of patients with CKD receiving standard-of-care therapy, and mortality in CKD remains unchanged. These data suggest that key pathogenetic mechanisms underlying CKD progression go unaffected by current treatments. Growing evidence suggests that nonalcoholic fatty liver disease (NAFLD) and CKD share common pathogenetic mechanisms and potential therapeutic targets. Common nutritional conditions predisposing to both NAFLD and CKD include excessive fructose intake and vitamin D deficiency. Modulation of nuclear transcription factors regulating key pathways of lipid metabolism, inflammation, and fibrosis, including peroxisome proliferator-activated receptors and farnesoid X receptor, is advancing to stage III clinical development. The relevance of epigenetic regulation in the pathogenesis of NAFLD and CKD is also emerging, and modulation of microRNA21 is a promising therapeutic target. Although single antioxidant supplementation has yielded variable results, modulation of key effectors of redox regulation and molecular sensors of intracellular energy, nutrient, or oxygen status show promising preclinical results. Other emerging therapeutic approaches target key mediators of inflammation, such as chemokines; fibrogenesis, such as galectin-3; or gut dysfunction through gut microbiota manipulation and incretin-based therapies. Furthermore, NAFLD per se affects CKD through lipoprotein metabolism and hepatokine secretion, and conversely, targeting the renal tubule by sodium-glucose cotransporter 2 inhibitors can improve both CKD and NAFLD. Implications for the treatment of NAFLD and CKD are discussed in light of this new therapeutic armamentarium.

    Critical limb ischemia (CLI) in high surgical risk patients with chronic liver diseases has a grave prognosis with a one-year mortality rate of 20% and a one-year amputation rate of 25% after the initial diagnosis. According to Trans-Atlantic Inter-Society Consensus (TASC)-II Guidelines, revascularization (surgical & endovascular) is the treatment of choice for patients with critical limb ischemia (CLI). The primary goal of revascularization is to relieve ischemic rest pain, heal ulcers, prevent amputation, improve patient's quality of life (limb salvage) and secondary goal was the periprocedural complications. Endovascular techniques include balloon angioplasty, stents, stent-grafts, and plaque debulking procedures. Surgical options, identification of patients at risk of postoperative complications could have an impact on the indications for a procedure as well as permitting modifications of treatment to reduce the surgical risk This study evaluated the treatment out comas after limb salvage angioplasty for patients who otherwise would be candidates for primary amputation due to poor co-morbid conditions as chronic liver disease and diabetes. The clinical evaluation, laboratory investigations and abdominal ultrasonography were performed to all patients to evaluate their liver status. Patients were classified according to Child-pugh classification into child A, B & C. All patients were subjected to either detailed arterial duplex or C.T. angiography to assess their arterial lesions from January 2008- January 2010. 95 patients with critical limb ischemia (Rutherford categories 4, 5, 6) were treated by primary percutaneous transluminal angioplasty (PTA). No patient was excluded on the basis of the extent of arterial occlusive disease. The primary end points were immediate technical success, clinical improvement and limb salvages rates. Secondary end points were periprocedural complications and mortality. Most of the patients were male (54.7%) with mean age 62 (48

    Full Text Available Abstract Background Hepatopulmonary syndrome (HPS is a rare complication of liver diseases of different etiologies and may indicate a poor prognosis. Therefore, a simple non-invasive screening method to detect HPS would be highly desirable. In this study pulse oximetry was evaluated to identify patients with HPS. Methods In 316 consecutive patients with liver cirrhosis (n = 245, chronic hepatitis (n = 69 or non-cirrhotic portal hypertension (n = 2 arterial oxygen saturation (SaO2 was determined using a pulse oximeter. In patients with SaO2 ≤92% in supine position and/or a decrease of ≥4% after change from supine to upright position further diagnostic procedures were performed, including contrast-enhanced echocardiography and perfusion lung scan. Results Seventeen patients (5.4% had a pathological SaO2. Four patients (1.3% had HPS. HPS patients had a significant lower mean SaO2 in supine (89.7%, SD 5.4 vs. 96.0%, SD 2.3; p = 0.003 and upright position (84.3%, SD 5.0 vs. 96.0%, SD 2.4; p = 0.001 and had a lower mean PaO2 (56.2 mm Hg, SD 15.2 vs. 71.2 mm Hg, SD 20.2; p = 0.02 as compared to patients without HPS. The mean ΔSaO2 (difference between supine and upright position was 5.50 (SD 7 in HPS patients compared to non-HPS patients who showed no change (p = 0.001. There was a strong correlation between shunt volume and the SaO2 values (R = -0.94. Conclusion Arterial SaO2 determination in supine and upright position is a useful non-invasive screening test for HPS and correlates well with the intrapulmonary shunt volume.

    significant differences among Ci A, Ci B and Ci C. Statistically significant differences were also between the group of steatofibrosis and whole group of cirrhosis. The concentration of MEGX 15 and 30 minutes after lidocaine administration correlated significantly with the values of albumin, prothrombin time, cholinesterase, Child-Plugh score and bilirubin. MEGX test represents an appropriate and rapid method for the determination of functional liver capacity in patients with liver cirrhosis and liver steatofibrosis, not yet used in Slovak republic. It is a noninvasive test, low time consuming, and when repeated it may provide prognostic information about further development of the disease. MEGX test is an appropriate index of liver function and may contribute to early treatment of chronic liver diseases. (Tab. 9, Fig. 10, Ref. 47.)

  5. Liver in systemic disease

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    Potential causes of abnormal liver function tests include viral hepatitis, alcohol intake, nonalcoholic fatty liver disease, autoimmune liver diseases, hereditary diseases, hepatobiliary malignancies or infection, gallstones and drug-induced liver injury. Moreover, the liver may be involved in systemic diseases that mainly affect other organs. Therefore, in patients without etiology of liver injury by screening serology and diagnostic imaging, but who have systemic diseases, the abnormal liver function test results might be caused by the systemic disease. In most of these patients, the systemic disease should be treated primarily. However, some patients with systemic disease and severe liver injury or fulminant hepatic failure require intensive treatments of the liver.

    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.

    One hundred and fifty-two biopsies from serologically HBsAg positive and negative patients with liver disease were studied in immunofluorescence: for the presence of the surface (HBs) and the core (HBc) antigenic determinants foeterminants of the hepatitis B virus, of immunoglobulins and complement (C) deposits, and for the capacity to fix human C. Circumstantial evidence is presented suggesting that HBc immune-complexes are a relevant feature in the establishment and progression of chronic HBSAg liver disease. C fixation by liver cells was shown in all HBC positive patients with chronic hepatitis; an active form was present in every case, except two with a persistent hepatitis, an inverse ratio of HBc to C binding fluorescence being noted between active chronic hepatitis and cirrhotic patients. HBc without C fixation was observed in only three patients in the incubation phase of infectious hepatitis. IgG deposits were often found in HBc containing, C fixing nuclei. No C binding or IgG deposits were observed in acute self-limited type B hepatitis, in serologically positive patients with normal liver or minimal histological lesions, with and without HBs cytoplasmic fluorescence in their biopsy, or in serologically negative individuals.

    Chronic liver disease is the fifth leading cause of death worldwide and represents a major burden for the health care community. Cirrhosis is a progressive disease resulting in end-stage liver failure, which in the absence of liver transplantation is fatal. Acute-on-chronic liver failure carries high short-term mortality but is potentially reversible. Viral hepatitis, alcohol, and nonalcoholic fatty liver disease remain the principal causes of liver disease. Though treatments exist for hepatitis B and C, they remain unavailable to many with these diseases. This article reviews the epidemiology of advanced liver disease and the concept of acute-on-chronic liver failure.

    Full Text Available Vaccination against hepatitis A virus (HAV has been recommended in patients with chronic liver disease to prevent any decompensation due to superinfection. This may not hold good in high endemic areas for hepatitis A like India. The aim of this study was to find out the seroprevalence of anti-HAV antibodies in patients with chronic liver disease and to justify the need for vaccination against hepatitis A virus in these patients. One hundred and thirty three consecutive patients with cirrhosis of liver attending Gastroenterology department of our Institute between June 2004 and June 2005 were enrolled. Seventy-five healthy persons were taken as controls. The diagnosis of cirrhosis was based on clinical profile, biochemical, radiological (ultrasound abdomen and endoscopic findings. The etiology of cirrhosis was based on presence of viral markers, history of significant alcohol consumption, autoimmune and metabolic workup. All patients and controls were tested for antiHAV (total antibodies using commercially available enzyme-linked immunosorbent assay kits. Data from patients and control group were compared by unpaired ′t′ test and Chi square test. All subjects were in the age group 11 to 75 years. Etiology of chronic liver disease was as follows: HBV- 29.3%, HCV - 14.28%, HBV+HCV dual -1.5%, alcohol- 21.8%, Cryptogenic -23.3%, Wilson"s Disease -1.5% and Budd chiari -1.5%. The prevalence of HAV was 93.2% in patients with cirrhosis of liver and 94.6% in controls. The prevalence was almost similar irrespective of the etiology. In view of high seroprevalence of HAV antibodies among cirrhotic patients in our study and the high cost of the vaccine, the hepatitis A vaccination may not be routinely required in this part of the world.

    Martin L Decaris

    Full Text Available Accumulation and degradation of scar tissue in fibrotic liver disease occur slowly, typically over many years. Direct measurement of fibrogenesis, the rate of scar tissue deposition, may provide valuable therapeutic and prognostic information. We describe here results from a pilot study utilizing in vivo metabolic labeling to measure the turnover rate of hepatic collagen and collagen-associated proteins in plasma for the first time in human subjects. Eight subjects with chronic liver disease were labeled with daily oral doses of 2H2O for up to 8 weeks prior to diagnostic liver biopsy and plasma collection. Tandem mass spectrometry was used to measure the abundance and fractional synthesis rate (FSR of proteins in liver and blood. Relative protein abundance and FSR data in liver revealed marked differences among subjects. FSRs of hepatic type I and III collagen ranged from 0.2-0.6% per day (half-lives of 4 months to a year and correlated significantly with worsening histologic fibrosis. Analysis of plasma protein turnover revealed two collagen-associated proteins, lumican and transforming growth factor beta-induced-protein (TGFBI, exhibiting FSRs that correlated significantly with FSRs of hepatic collagen. In summary, this is the first direct measurement of liver collagen turnover in vivo in humans and suggests a high rate of collagen remodeling in advanced fibrosis. In addition, the FSRs of collagen-associated proteins in plasma are measurable and may provide a novel strategy for monitoring hepatic fibrogenesis rates.

    Full Text Available Background: Nosocomial urinary tract infections (UTIs are common in catheterized patients. Fungal UTI has become an important nosocomial problem over the past decade. The microbiology of candiduria is rapidly evolving and new trends are being reported. Aims: To study the microbiological trends and antifungal resistance profile of Candida in urine of catheterized chronic liver disease (CLD patients at a super specialty hepatobiliary tertiary-care center. Materials and Methods: urine samples were collected by sterile technique, processed by semi-quantitative method as per the standard protocols. Direct microscopic examination of urine sample was also done to look for the presence of pus cells, red blood cells, casts, crystals or any bacterial or fungal element. Result: A total of 337 yeast isolates were obtained from catheterized patients, non-albicans Candida spp. emerged as the predominant pathogen and was responsible for 67.06% of nosocomial fungal UTI. Candida tropicalis accounted for 34.71% of the cases, whereas Candida albicans grew in 32.93%, Candida glabrata 16.32%, rare Candida spp. Nearly 11.5% (Candida hemolunii to be confirmed by molecular methods. Antifungal sensitivity varied non-albicans species except C. tropicalis, Candida parapsilosis were more often resistant to antifungal drugs. Conclusion: Nosocomial Candida UTIs in CLD patients is common, due to the cumulative pressure of contributing factors such as urinary instrumentation and prolonged use of broad-spectrum antibiotics. Non-albicans Candida were found to outnumber C. albicans in catherized CLD patients. Risk of strain persistence is also higher with non-albicans Candida. Thus, species identification and susceptibility testing is a must for appropriate management of such patients.

    Osteoporosis is a major complication of chronic cholestatic liver disease (CCLD). We evaluated the efficacy of using disodium pamidronate (1.0 mg/kg body weight) for the prevention (Pr) or treatment (Tr) of cholestasis-induced osteoporosis in male Wistar rats: sham-operated (Sham = 12); bile duct-ligated (Bi = 15); bile duct-ligated animals previously treated with pamidronate before and 1 month after surgery (Pr = 9); bile duct-ligated animals treated with pamidronate 1 month after surgery (Tr = 9). Rats were sacrificed 8 weeks after surgery. Immunohistochemical expression of IGF-I and GH receptor was determined in the proximal growth plate cartilage of the left tibia. Histomorphometric analysis was performed in the right tibia and the right femur was used for biomechanical analysis. Bone material volume over tissue volume (BV/TV) was significantly affected by CCLD (Sham = 18.1 ± 3.2 vs Bi = 10.6 ± 2.2%) and pamidronate successfully increased bone volume. However, pamidronate administered in a preventive regimen presented no additional benefit on bone volume compared to secondary treatment (BV/TV: Pr = 39.4 ± 12.0; Tr = 41.2 ± 12.7%). Moreover, the force on the momentum of fracture was significantly reduced in Pr rats (Sham = 116.6 ± 23.0; Bi = 94.6 ± 33.8; Pr = 82.9 ± 22.8; Tr = 92.5 ± 29.5 N; P < 0.05, Sham vs Pr). Thus, CCLD had a significant impact on bone histomorphometric parameters and pamidronate was highly effective in increasing bone mass in CCLD; however, preventive therapy with pamidronate has no advantage regarding bone fragility.

    Full Text Available Abstract Background Spontaneous bacterial peritonitis (SBP is a serious complication in infants and children with chronic liver disease (CLD; however its diagnosis might be difficult. We aimed to study the feasibility of diagnosing SBP by routine ascitic fluid tapping in infants and children with CLD. Methods We enrolled thirty infants and children with biopsy-proven CLD and ascites. Ascitic fluid was examined for biochemical indices, cytology and cell count. Aerobic and anaerobic bacteriological cultures of ascitic fluid were preformed. Direct smears were prepared from ascitic fluid deposit for Gram and Zheil-Nelson staining. Results Patients were divided into three groups: Group I included five patients with SBP in which the cell count was ≥ 250/mm3 and culture was positive (16.7%, Group II, eight patients with culture negative neutrocytic ascites (CNNA with cells ≥ 250/mm3 and negative culture (26.7% and Group III, seventeen negative patients (56.6% in which cells were 3 and culture was negative. None of our patients had bacteriascites (i.e. culture positive with cells 3. Presence of fever was significantly higher in SBP and CNNA. The mean lactate dehydrogenase (LDH level was significantly higher in ascitic fluid in the infected versus sterile cases (p Conclusions SBP is a rather common complication in children with CLD. Culture of the ascitic fluid is not always diagnostic of infection. Biochemical parameters of the ascitic fluid definitely add to the diagnostic accuracy. LDH ascitic/serum ratio ≥ 0.5, an arterial-ascitic pH gradient ≥ 0.1 and total ascitic fluid protein ≤ 1 gm/dl are the most significant parameters suggesting infection.

    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.

    Purpose: To evaluate the safety and feasibility of percutaneous transsplenic access to the portal vein for management of vascular complication in patients with chronic liver diseases. Methods: Between Sept 2009 and April 2011, percutaneous transsplenic access to the portal vein was attempted in nine patients with chronic liver disease. Splenic vein puncture was performed under ultrasonographic guidance with a Chiba needle, followed by introduction of a 4 to 9F sheath. Four patients with hematemesis or hematochezia underwent variceal embolization. Another two patients underwent portosystemic shunt embolization in order to improve portal venous blood flow. Portal vein recanalization was attempted in three patients with a transplanted liver. The percutaneous transsplenic access site was closed using coils and glue. Results: Percutaneous transsplenic splenic vein catheterization was performed successfully in all patients. Gastric or jejunal varix embolization with glue and lipiodol mixture was performed successfully in four patients. In two patients with a massive portosystemic shunt, embolization of the shunting vessel with a vascular plug, microcoils, glue, and lipiodol mixture was achieved successfully. Portal vein recanalization was attempted in three patients with a transplanted liver; however, only one patient was treated successfully. Complete closure of the percutaneous transsplenic tract was achieved using coils and glue without bleeding complication in all patients. Conclusion: Percutaneous transsplenic access to the portal vein can be an alternative route for portography and further endovascular management in patients for whom conventional approaches are difficult or impossible.

    Infection with hepatitis A virus (HAV) in patient with chronic liver disease (CLD; due to hepatitis B or hepatitis C) may cause severe disease and fulminant liver failure. This study aimed to determine the seroprevalence of HAV antibodies in patients infected with HCV or HBV in Iran (Jahrom city). A total of 159 patients with underlying CLD were recruited between September 2012 and February 2013. Serum samples were collected from each patient and tested for anti-HAV using enzyme-linked immunosorbent assay (ELISA). The overall seroprevalence of total anti-HAV was 79·2%. Patients aged 20-30 years had the lowest (28·3%) anti-HAV seropositivity and those aged >50 years had the highest (95%) seropositivity. The overall prevalence of anti-HAV in patients with chronic HCV and HBV infection was 93·7% and 77·1%, respectively. The anti-HAV seropositivity in liver cirrhosis patients was 100% compared to CLD patients. Because of low HAV immunity in younger CLD patients, vaccination against HAV should be considered.

    AIM: To study a more accurate quantification of hepatic fibrosis which would provide clinically useful information for monitoring the progression of chronic liver disease.METHODS: Using a cDNA microarray containing over 22000 clones, we analyzed the gene-expression profiles of non-cancerous liver in 74 patients who underwent hepatic resection. We calculated the ratio of azan stained: total area, and determined the morphologic fibrosis index (MFI), as a mean of 9 section-images. We used the MFI as a reference standard to evaluate our method for assessing liver fibrosis.RESULTS: We identified 39 genes that collectively showed a good correlation (r>0.50) between geneexpression and the severity of liver fibrosis. Many of the identified genes were involved in immune responses and cell signaling. To quantify the extent of liver fibrosis,we developed a new genetic fibrosis index (GFI) based on gene-expression profiling of 4 clones using a linear support vector regression analysis. This technique, based on a supervised learning analysis, correctly quantified the various degrees of fibrosis in both 74 training samples (r= 0.76, 2.2% VS 2.8%, P<0.0001) and 12 independent additional test samples (r = 0.75, 9.8% vs 8.6%, P<0.005). It was far better in assessing liver fibrosis than blood markers such as prothrombin time (r= -0.53),type Ⅳ collagen 7s (r = 0.48), hyaluronic acid (r = 0.41),and aspartate aminotransferase to platelets ratio index(APRI) (r= 0.38).CONCLUSION: Our cDNA microarray-based strategy may help clinicians to precisely and objectively monitor the severity of liver fibrosis.

    Wilson's disease is a hereditary autosomal recessive disorder of copper metabolism,characterized by copper accumulation in the liver and brain. This rare entity, which has a broad clinical spectrum, is often difficult to diagnose and should therefore always be suspected in patients with liver disease of unclear cause. We describe two types of manifestation of liver disease in two patients; the first developed fulminant hepatic failure requiring urgent liver transplantation and the second showed advanced chronic liver disease and received standard medical treatment. The objective of this clinical observation is to analyze the diagnosis of Wilson's disease in two patients with distinct onset, illustrating the broad clinical spectrum of the disease, and its treatment.

    Aim: To test the hypothesis that the traditional Chinese medicine Cordyceps sinensis could improve the metabolic function of extrarenal organs to achieve its anti-chronic kidney disease (CKD) effects. Methods: Male SD rats were divided into CKD rats (with 5/6-nephrectomy), CKD rats treated with Cordyceps sinensis (4 mg•kg-1•d-1, po), and sham-operated rats. After an 8-week treatment, metabolites were extracted from the hearts and livers of the rats, and then subjected to 1H-NMR-based metabolomic analysis. Results: Oxidative stress, energy metabolism, amino acid and protein metabolism and choline metabolism were considered as links between CKD and extrarenal organ dysfunction. Within the experimental period of 8 weeks, the metabolic disorders in the liver were more pronounced than in the heart, suggesting that CKD-related extrarenal organ dysfunctions occurred sequentially rather than simultaneously. Oral administration of Cordyceps sinensis exerted statistically significant rescue effects on the liver and heart by reversely regulating levels of those metabolites that are typically perturbed in CKD. Conclusion: Oral administration of Cordyceps sinensis significantly attenuates the liver and heart injuries in CKD rats. The 1H NMR-based metabolomic approach has provided a systematic view for understanding of CKD and the drug treatment, which can also be used to elucidate the mechanisms of action of other traditional Chinese medicines.

    Full Text Available Background/Aim: Type 2 diabetes mellitus (DM-2 is more common in patients with chronic liver disease (CLD in general and chronic hepatitis C virus (HCV infection in particular. We aimed to determine the prevalence and factors affecting the occurrence of DM-2 in Saudi patients with CLD. Materials and Methods: Retrospective study at the King Fahd Central Hospital (KFCH, Gizan, Saudi Arabia. A total of 277 patients with either cirrhosis (CH or hepatocellular carcinoma (HCC were analyzed for patient demographics, severity of liver disease, HBsAg, and anti-HCV, associated diseases including DM-2, and presence of HCC. The prevalence of DM-2 was also estimated in 400 age- and sex-matched Saudi patients admitted for various nonliver diseases (control group. Chi-square test, univariate analysis, and multivariate regression. Results: Prevalence of DM-2 in patients with CH was higher than in controls (19.2 vs. 9.2%; P = 0.001. Although those with HCC had a higher prevalence, the difference was not significant (10.9 vs. 9.2%; P = 0.5. Seventy-six percent of patients with HCC had associated CH. On multivariate analysis, age and hypertension were more common in diabetics. Although patients with HCV-related disease had a higher prevalence of DM-2 compared to HBV-related disease, the difference was not significant (26.3 vs. 15.7%; P > 0.05. Conclusions: DM-2 occurred more frequently in CLD patients, particularly in cirrhotics. Age and hypertension predicted the occurrence of DM-2. Small sample size of patients with HCV-related CH probably precluded higher prevalence of DM-2 in them.

    Full Text Available Positron emission tomography (PET using the radiopharmaceutical tracer fluorine-18 fluorocholine (FCh can elucidate tumors based on differences in choline phospholipid metabolism between tumor and surrounding tissue. The feasibility of detecting hepatocellular carcinoma (HCC using FCh PET has been shown despite constitutively high parenchymal choline metabolism in the liver. Since HCC frequently develops in the setting of chronic liver disease, we comparatively evaluated FCh PET/CT between cirrhotic and non-cirrhotic patients with HCC to investigate the effects of hepatic dysfunction on tumor detection and the tumor-to-background ratio (TBR of FCh uptake. FCh PET/CT was performed prospectively in 22 consecutive patients with HCC (7 newly diagnosed, 15 previously treated. Of these 22 patients, 14 were cirrhotic and 8 non-cirrhotic. Standardized uptake value (SUV measurements were obtained by region of interest analysis of the PET images. Tumor FCh uptake and the TBR were compared between cirrhotic and non-cirrhotic patients. Liver lesions were confirmed to be HCC by biopsy in 10 patients and by Barcelona criteria in 4 patients. There was correspondingly increased liver tumor FCh uptake in 13/14 of those patients, and iso-intense tumor FCh uptake (TBR 0.94 in one non-cirrhotic patient with newly diagnosed HCC. FCh PET/CT also showed metastatic disease without local tumor recurrence in 2 previously treated patients, and was negative in 6 treated patients without tumor recurrence by radiographic and clinical follow-up. Tumor maximum SUV ranged from 6.4 to 15.3 (mean 12.1 and liver TBR ranged from 0.94 to 2.1 (mean 1.6, with no significant differences between cirrhotic and non-cirrhotic patients (SUVmax 11.9 vs. 12.2, p = 0.83; TBR 1.71 vs. 1.51, p = 0.29. Liver parenchyma mean SUV was significantly lower in cirrhotic patients (6.4 vs. 8.7, p < 0.05. This pilot study supports the general feasibility of HCC detection by FCh PET/CT. However, a broad

    Full Text Available Background: Variceal bleeding is an important complication of portal hypertension and a major cause of death in patients with chronic liver disease (CLD world wide. This study was carried out to document the occurrence of oesophageal varices and its clinical correlates among 80 Nigerian patients with CLD. Patients and Methods: Eighty patients with CLD were stratified into three groups based on Child- Turcotte- pugh′s classification for severity of CLD in a one year study. They had upper gastrointestinal endoscopy to detect and characterize varices. Results: Sixty (75% of the patients had oesophageal varices at endoscopy with 88.3% having grade 2 or 3 varices while 73.3% had moderate/large varices. Thirty five percent of the varices had "red signs" with "red whale" markings as the predominant red sign. Gastric varices were seen in 12.5%. Variceal size was significantly associated with severity of liver disease (P<0.05 as 90% of the patients with varices presented with Child′s class B or C. A multiple logistic regression analysis identified advancing age, ascites, shrunken liver span and low platelet count as independent predictors of oesophageal varices. Conclusion: A large proportion of Nigerian CLD patients have advanced at-risk-for-bleeding oesophageal varices at diagnosis. Early diagnosis of CLD in Nigerians is warranted.

    AIM: Clinical and experimental data suggest that gut-derived endotoxins are an important pathogenic factors for progression of chronic liver disease. Recently, a C-T (-159)polymorphism in the promoter region of the CD14 gene was detected and found to confer increased CD14 expression and to be associated with advanced alcoholic liver damage. Here, we investigated this polymorphism in patients with less advanced alcoholic liver disease (ALD)and chronic hepatitis C virus (HCV) infection.METHODS: CD14 genotyping was performed by PCR-RFLP analysis in (a) 121 HCV patients, (b) 62 patients with alcohol-associated cirrhosis (Alc-Ci), (c) 118 individuals with heavy alcohol abuse without evidence of advanced liver damage (Alc-w/o Ci), and (d) 247 healthy controls.Furthermore, serum levels of soluble CD14 (sCD14) and transaminases were determined.RESULTS: The TT genotype was significantly more frequent in Alc-Ci compared to Alc-w/o Ci or controls (40.3% vs 23.7% or 24.0%, respectively). In Alc-w/o Ci,serum levels of transaminases did not differ significantly between patients with different CD14 genotypes. In HCV patients, TT-homozygotes had significantly higher sCD14 levels and sCD14 serum levels were significantly higher in patients with advanced fibrosis or cirrhosis. However,no association was found between CD14 genotypes and histological staging or grading.CONCLUSION: Considering serum transaminases as surrogate markers for alcoholic liver damage, the CD14 polymorphism seems to exhibit different effects during the course of ALD. Differences in genotype distribution between cirrhotic HCV patients and alcoholics and the known functional impact of this polymorphism on CD14 expression levels further indicate differences in the pathophysiological role of CD14 and CD14-mediated lipopolysaccharides signal transduction with regard to the stage as well as the type of the underlying liver disease.

    Autoimmune hepatitis is a chronic hepatitis of unknown etiology characterized by clinical, histological, and immunological features, generally including circulating autoantibodies and a high total serum and/or gamma globulin. Liver-related autoantibodies are very significant for the correct diagnosis and classification of autoimmune liver diseases (AILD), namely autoimmune hepatitis types 1 and 2 (AIH-1 and 2), primary biliary cirrhosis (PBC), and the sclerosing cholangitis types in adults and children. This article intends to review recent studies that investigate autoantibodies in autoimmune liver diseases from a microbiological perspective.

    Objective The study aimed to evaluate the prevalence and predictor factors for compensated advanced chronic liver disease (c-ACLD) in patients with hepatitis Delta virus (HDV) infection. Methods This cross-sectional study included consecutive HDV-infected patients defined by positive anti-HDV. Patients with hepatitis C coinfection, liver transplantation or presence of conditions that limit liver (LSM) or spleen stiffness measurement (SSM) were excluded. Blood tests, abdominal ultrasound, SSM and LSM by transient elastography (FibroScan®) were performed at the same day. Alcohol consumption was quantified using the AUDIT score and c-ACLD was defined by LSM ≥ 15 kPa performed by an experimented operator blinded for clinical and laboratory data. Results 101 patients were eligible and few patients were excluded due to negative anti-HDV (n = 7), hepatitis C coinfection (n = 2), liver transplantation (n = 10) and limitation for LSM or SSM (n = 5). Therefore, 77 patients [61% male, age = 43 (IQR,36–52) years] were included. The prevalence of c-ACLD was 57% (n = 44/77). Patients with c-ACLD had a higher rate of detectable HBV viral load (p = 0.039), higher levels of transaminases, GGT, alkaline phosphatases, total bilirubin and INR (p0.001 for both) compared to those without c-ACLD. Patients with c-ACLD had higher SSM [65.2 (IQR,33.8–75.0) vs 21.8 (16.5–32.0) kPa; p10 UI/ml), alkaline phosphatase (per IU/L) and GGT levels (per IU/L) were independently associated with c-ACLD in all multivariate models. Splenic volume [per cm3,OR = 1.01 (95%CI,1.01–1.02);p = 0.002], SSM [per kPa, OR = 1.04 (1.01–1.07);p = 0.012] and splenomegaly [yes vs no,OR = 28.45 (4.42–182.95);p<0.001] were independently associated with c-ACLD. Conclusions The prevalence of c-ACLD was high in patients with chronic HDV infection in western Amazon basin. HBV viral load, liver enzymes and splenic features can be used to predict severe liver disease in HDV-infected patients. PMID:28329027

    Full Text Available Background: In recent years the ratio of aspartate aminotransferase (AST to alanine aminotransferase (ALT in patients of chronic liver disease (CLD of various origins has gained much attention. This variable is readily available, easy to interpret, and inexpensive and the clinical utility of the AST/ALT ratio in the diagnostic workup of patients with CLD is quite promising. Objective: The present study was designed to find out the link between aminotransferase (AST/ALT ratio with commonly measured biochemical parameters of liver function tests in CLD of viral origin. Materials and method: This cross sectional study was carried out in the department of Biochemistry, Sir Salimullah Medical College, Dhaka, Bangladesh. Forty four biopsy proven diagnosed subjects of chronic viral hepatitis without cirrhosis of both sex were selected purposively. With aseptic precaution 5 mL venous blood was collected from each subject and common liver function tests (serum AST, ALT, AST/ALT ratio, alkaline phosphatase, total bilirubin, serum total protein, serum albumin, serum globulin, serum albumin/globulin ratio, prothrombin time and viral serology (HBsAg, Anti HDV antibody, Anti HCV antibody were performed. Data were analyzed by SPSS version 19 for Windows. Pearson’s correlation test was done to determine association between AST/ALT with other biochemical parameters. Results: Mean(±SD age of the study subjects was 32.55±10.55 years (range 20-50 years with 48 (77.7% male and 14 (22.6% female subjects. Pearson’s correlation test was done between AST to ALT ratio with other biochemical parameters and prothrombin time showed significant positive correlation (p <0.01. Conclusion: In our study we found significant positive correlation between AST/ALT with prothrombin time in CLD subjects without cirrhosis.

    Full Text Available Patients with advanced hepatic failure may present with the entire spectrum of coagulation factor deficiencies. This study was designed to determine laboratory abnormalities in coagulation in chronic liver disease and the association of these abnormalities with the extent of chronic hepatitis and cirrhosis. Coagulation markers were assayed in 60 participants: 20 patients with chronic hepatitis, 20 patients with cirrhosis, and 20 healthy individuals (control. Plasma levels of anti-thrombin III were determined by a chromogenic substrate method, and plasma concentrations of fibrinogen were analyzed by the Rutberg method. Commercially available assays were used for laboratory coagulation tests. The levels of coagualation activity markers in patients with chronic liver disease were significantly different in comparison to those in healthy participants. These results indicate the utility of measuring markers for coagulation activity in determining which cirrhosis patients are more susceptible to disseminated intravascular coagulation.

    Full Text Available Hypoglycemia is a common, potentially fatal, yet preventable problem. Drug-induced hypoglycemia remains the commonest cause of hypoglycemia. A 63 year old non-diabetic male, a known case of chronic liver disease, on regular medications, presented with unconsciousness, unresponsiveness since two hours. Immediate random blood sugar was 11 mg/dl. On proper history and clinical examination, diagnosis of oral hypoglycemic agent induced hypoglycemic coma was made and immediately intravenous dextrose resuscitation was started. Patient regained consciousness after four hours and became fully oriented after 24 hours. Throughout his hospital course, strict and frequent glucose monitoring was done and dextrose infused accordingly. Patient remained hemodynamically stable throughout the hospital course. He was discharged from the hospital after 72 hours in an otherwise healthy condition. Drug induced hypoglycemia is now so relatively common that virtually every unconscious patient should be considered hypoglycemic until immediate estimation of the blood sugar level rules the condition in or out.

  2. Role of antiviral therapy in the natural history of hepatitis Bvirus-related chronic liver disease

    Institute of Scientific and Technical Information of China (English)

    2015-01-01

    Hepatitis B virus (HBV) infection is a dynamic state of interactions among HBV, hepatocytes, and the hostimmune system. Natural history studies of chronichepatitis B (CHB) infection have shown an associationbetween active viral replication and adverse clinicaloutcomes such as cirrhosis and hepatocellular carcinoma.The goal of therapy for CHB is to improve quality of lifeand survival by preventing progression of the diseaseto cirrhosis, decompensation, end-stage liver disease,hepatocellular carcinoma (HCC) and death. This goalcan be achieved if HBV replication is suppressed ina sustained manner. The accompanying reduction inhistological activity of CHB lessens the risk of cirrhosisand of HCC, particularly in non-cirrhotic patients.However, CHB infection cannot be completely eradicated,due to the persistence of covalently closed circular DNAin the nucleus of infected hepatocytes, which may explainHBV reactivation. Moreover, the integration of the HBVgenome into the host genome may favour oncogenesis,development of HCC and may also contribute to HBVreactivation.

    Cholestatic liver diseases include a group of diverse disorders with different epidemiology, pathophysiology, clinical course, and prognosis. Despite significant advances in the clinical care of patients with cholestatic liver diseases, liver transplant (LT) remains the only definitive therapy for end-stage liver disease, regardless of the underlying cause. As per the United Network for Organ Sharing database, the rate of cadaveric LT for cholestatic liver disease was 18% in 1991, 10% in 2000, and 7.8% in 2008. This review summarizes the available evidence on various common and rare cholestatic liver diseases, disease-specific issues, and pertinent aspects of LT.

    Clinical observations suggest that chronic hepatitis B virus (HBV) infections in the Canadian Inuit are less often associated with serious adverse outcomes than has been described in other HBV-infected patient populations. The aim of this study was to document the clinical and biochemical features, liver-related morbidity and all-cause mortality in Canadian Inuit with chronic HBV infections. Administrative databases were reviewed for individuals identified as hepatitis B surface antigen (HBsAg) positive during a 1983-85 seroepidemiological survey of viral hepatitis in Baffin Island, Canada. An equal number of age- and gender-matched HBsAg-negative individuals from the same communities served as controls. Baseline HBV viral loads, genotypes and specific mutations were compared in HBsAg-positive survivors and nonsurvivors. A subset of surviving HBsAg-positive carriers were reassessed 25-30 years following their initial diagnosis for evidence of advanced liver disease and changes to their serological/virological findings. One hundred and forty four HBsAg-positive individuals were identified. All were Canadian Inuit. The mean age at diagnosis was 38 ± 17 years and 69 (61%) were male. Median follow-up was 23 years (range: 2-28 years). Viral quantitation from stored sera could be performed in 70 infected individuals. The median viral load was 4.3 log 10 IU/ml (range: 2.3-8.8 log 10 IU/ml), and all were genotype B, subgenotype B6. Liver biochemistry, morbidity and all-cause mortality rates were similar in HBsAg-positive carriers and controls. Following multivariate analyses, only age at diagnosis predicted mortality in HBsAg carriers. In a subset of 30 HBsAg-positive survivors who underwent follow-up assessments, clinical, biochemical and radiological examinations of the liver were essentially normal. 23/30 (77%) remained HBsAg positive and 17/19 (90%) HBV-DNA positive. The genotype and prevalence of genomic mutations in this cohort remained largely unchanged, but

    AIM: To determine whether parenchymal cells or hepaticcytochrome P450 protein was changed in chronic liverdiseases, and to compare the difference of CYP3A4 enzymeand its gene expression between patients with hepaticcirrhosis and obstructive jaundice, and to investigate thepharmacologic significance behind this difference.METHODS: Liver samples were obtained from patientsundergoing hepatic surgery with hepatic cirrhosis (n=6) andobstructive jaundice (n=6) and hepatic angeioma (controls,n=6). CYP3A4 activity and protein were determined by Nashand western bloting using specific polychonal antibody,respectively. Total hepatic RNA was extracted andCYP3A4cDNA probe was prepared according the methodof random primer marking, and difference of cyp3a4expression was compared among those patients byNorthern blotting.RESULTS: Compared to control group, the CYP3A4 activityand protein in liver tissue among patients with cirrhosis wereevidently reduced. (P<0.01) Northern blot showed the samechange in its mRNA levels. In contrast, the isoenzyme andits gene expression were not changed among patients withobstructive jaundice.CONCLUSION: Hepatic levels of P450s and its CYP3A4isoform activity were selectively changed in different chronicliver diseases. CYP3A4 isoenzyme and its activity declinedamong patients with hepatic cirrhosis as expression of cyp3a4gene was significantly reduced. Liver's ability to eliminatemany clinical therateutic drug substrates would declineconsequently, These findings may have practical implicationsfor the use of drugs in patients with cirrhosis and emphasizethe need to understand the metabolic fate of therapeuticcompounds. Elucidation of the reasons for these differentchanges in hepatic CYP3A4 may provide insight into morefundamental aspects and mechanisms of imparied liverfunction.

    Portal circulation can be evaluated in a relatively noninvasive way by per-rectal portal scintigraphy. We used this method to evaluate portal hemodynamics in patients with chronic liver diseases and underlying hepatic viral infection; the patients did not need surgery or sclerotherapy, or refused it, so changes in the natural course were identified. A solution of Tc-99m pertechnetate was instilled into the rectum, and serial scintigrams were taken while radioactivity curves for the liver and heart were produced. The per-rectal portal shunt index was calculated from the curves. In a longitudinal study, 70 patients (9 with mild chronic hepatitis, 10 with moderate chronic hepatitis, 7 with severe chronic hepatitis, 22 with cirrhosis but without varices, and 22 with both cirrhosis and varices) were examined at least twice at intervals of 12-102 months (mean, 39 months). The shunt index was higher for more severe disorders, increasing in the order of mild chronic hepatitis, moderate chronic hepatitis, severe chronic hepatitis, cirrhosis without varices, and cirrhosis with varices. The mean annual changes in the mean shunt index were 1.0% in mild chronic hepatitis, 4.4% in moderate chronic hepatitis, 6.1% in severe chronic hepatitis, 10.7% in cirrhosis without varices, and 6.2% in cirrhosis and varices. Cirrhotic patients were arbitrarily divided into two groups of roughly equal size on the basis of the shunt index at the first examination. In those with a shunt index of 30% or more, the mean annual change was 4.7%. The patients with a shunt index of less than 30% had a mean annual change of 11.8%. Changes in the portal hemodynamics were not steady. The shunt index rose gradually as disease advanced from mild to moderate and to severe chronic hepatitis and cirrhosis of the liver, after which the index rose rapidly when varices developed, slowing later.

    A personal health system platform for the management of patients with chronic liver disease that incorporates a novel approach to integrate decision support and guidance through care pathways for patients and their doctors is presented in this paper. The personal health system incorporates an integrated decision support engine that guides patients and doctors through the management of the disease by issuing tasks and providing recommendations to both the care team and the patient and by controlling the execution of a Care Flow Plan based on the results of tasks and the monitored health status of the patient. This Care Flow Plan represents a formal, business process based model of disease management designed off-line by domain experts on the basis of clinical guidelines, knowledge of care pathways and an organisational model for integrated, patient-centred care. In this way, remote monitoring and treatment are dynamically adapted to the patient's actual condition and clinical symptoms and allow flexible delivery of care with close integration of specialists, therapists and care-givers.

    The incidence of traffic accidents in patients with chronic liver disease (CLD) is high in the USA. However, the characteristics of patients, including dietary habits, differ between Japan and the USA. The present study investigated the incidence of traffic accidents in CLD patients and the clinical profiles associated with traffic accidents in Japan using a data-mining analysis. A cross-sectional study was performed and 256 subjects [148 CLD patients (CLD group) and 106 patients with other digestive diseases (disease control group)] were enrolled; 2 patients were excluded. The incidence of traffic accidents was compared between the two groups. Independent factors for traffic accidents were analyzed using logistic regression and decision-tree analyses. The incidence of traffic accidents did not differ between the CLD and disease control groups (8.8 vs. 11.3%). The results of the logistic regression analysis showed that yoghurt consumption was the only independent risk factor for traffic accidents (odds ratio, 0.37; 95% confidence interval, 0.16-0.85; P=0.0197). Similarly, the results of the decision-tree analysis showed that yoghurt consumption was the initial divergence variable. In patients who consumed yoghurt habitually, the incidence of traffic accidents was 6.6%, while that in patients who did not consume yoghurt was 16.0%. CLD was not identified as an independent factor in the logistic regression and decision-tree analyses. In conclusion, the difference in the incidence of traffic accidents in Japan between the CLD and disease control groups was insignificant. Furthermore, yoghurt consumption was an independent negative risk factor for traffic accidents in patients with digestive diseases, including CLD.

    Abstract A meta-analysis was performed to ascertain to what extent hepatitis B surface antigen (HBsAg)-negative/anti-hepatitis B core (anti-HBc)-positive subjects with chronic liver disease are at a higher risk of developing hepatocellular carcinoma (HCC) than the anti-HBc-negative. All studies included had to fulfill the following characteristics and inclusion criteria: they investigated the relationship between HBsAg-negative/anti-HBc-positive serology and the occurrence of HCC, whether a case–control or cohort study, they provided relative risk (RR) or odds ratios (ORs) and 95% confidence intervals (CIs), were available as a full text written in English, and were published and indexed up to April 2015. Twenty-six original studies met the inclusion criteria, allowing a meta-analysis on 44,553 patients. The risk of HCC among the 9986 anti-HBc-positive subjects was 67% higher than in the 34,567 anti-HBc-negative (95% CI = 1.44–1.95, P HCV and non-HCV) were considered. The risk of HCC was significantly higher in the 651 anti-HBs/anti-HBc-positive patients (RR = 1.36; 95% CI = 1.17–1.58, P = 0.03) and in the 595 anti-HBs-negative/anti-HBc-positive subjects (RR = 2.15; 95% CI = 1.58–2.92, P < 0.0001) than in the 1242 anti-HBs/anti-HBc negative. However, the RR from 8 studies indicated that the risk of HCC was 35% lower among the anti-HBs/anti-HBc-positive subjects compared to the anti-HBs-negative/anti-HBc-positive (RR = 0.65; 95% CI = 0.52–0.8, P < 0.0001). This meta-analysis shows that in HBsAg-negative subjects with chronic liver disease, anti-HBc positivity is strongly associated with the presence of HCC, an association observed in all subgroups according to the stage of the disease, etiology, and ethnicity.

    BACKGROUND: There is a growing evidence that matrix metalloproteinase (MMP)-2 and MMP-9 (gelatinases) play an important role in the pathogenesis of numerous disorders, especially with inflammatory etiology and extracellular matrix (ECM) remodeling. Despite the fact that gelatinases involve in liver cirrhosis is provided in the literature, their role in the pathogenesis of chronic pancreatitis and non-specific inflammatory bowel diseases is still under investigation. DATA SOURCES: We carried out a PubMed search of Englishlanguage articles relevant to the involvement of gelatinases in the pathogenesis of liver fibrosis, pancreatitis, and non-specific inflammatory bowel diseases. RESULTS: The decreased activity of gelatinases, especially MMP-2, is related to the development of liver fibrosis, probably due to the decrease of capability for ECM remodeling. Similar situation can be found in chronic pancreatitis; however, reports on this matter are rare. The presence of non-specific inflammatory bowel diseases results in MMP-9 activity elevation. CONCLUSION: The fluctuation of gelatinases activity during liver fibrosis, chronic pancreatitis and non-specific inflammatorybowel diseases is observed, but the exact role of these enzymes demands further studies.

    Kyu Sik Jung

    Full Text Available BACKGROUND & AIMS: Controlled attenuation parameter (CAP can measure hepatic steatosis. However, factors affecting its accuracy have not been described yet. This study investigated predictors of discordance between liver biopsy (LB and CAP. METHODS: A total of 161 consecutive patients with chronic liver disease who underwent LB and CAP were enrolled prospectively. Histological steatosis was graded as S0 (66% of hepatocytes. Cutoff CAP values were calculated from our cohort (250, 301, and 325 dB/m for ≥ S1, ≥ S2, and S3. Discordance was defined as a discrepancy of at least two steatosis stages between LB and CAP. RESULTS: The median age (102 males and 59 females was 49 years. Repartition of histological steatosis was as follows; S0 26.1% (n = 42, S1 49.7% (n = 80, S2 20.5% (n = 33, and S3 3.7% (n = 6. In multivariate linear regression analysis, CAP value was independently associated with steatosis grade along with body mass index (BMI and interquartile range/median of CAP value (IQR/MCAP (all P<0.05. Discordance was identified in 13 (8.1% patients. In multivariate analysis, histological S3 (odd ratio [OR], 9.573; 95% confidence interval [CI], 1.207-75.931; P = 0.033 and CAP value (OR, 1.020; 95% CI, 1.006-1.034; P = 0.006 were significantly associated with discordance, when adjusting for BMI, IQR/MCAP, and necroinflammation, reflected by histological activity or ALT level. CONCLUSIONS: Patients with high grade steatosis or high CAP values have a higher risk of discordance between LB and CAP. Further studies are needed to improve the accuracy of CAP interpretation, especially in patients with higher CAP values.

    Full Text Available Purpose. This study evaluated the long-term effects of alloxan-induced diabetes in rat liver. Methods. Thirty nondiabetic control rats (NC and 30 untreated diabetic (UD rats were divided into three subgroups sacrificed after 6, 14, or 26 weeks. Clinical and laboratory parameters were assessed. Fresh liver weight and its relationship with body weight were obtained, and liver tissue was analyzed. Results. UD rats showed sustained hyperglycemia, high glycosylated hemoglobin, and low plasma insulin. High serum levels of AST and ALT were observed in UD rats after 2 weeks, but only ALT remained elevated throughout the experiment. Fresh liver weight was equal between NC and UD rats, but the fresh liver weight/body weight ratio was significantly higher in UD rats after 14 and 26 weeks. UD rats showed liver morphological changes characterized by hepatic sinusoidal enlargement and micro- and macrovesicular hepatocyte fatty degeneration with progressive liver structure loss, steatohepatitis, and periportal fibrosis. Ultrastructural changes of hepatocytes, such as a decrease in the number of intracytoplasmic organelles and degeneration of mitochondria, rough endoplasmic reticulum, and nuclei, were also observed. Conclusion. Alloxan-induced diabetes triggered liver morphological and ultrastructural changes that closely resembled human disease, ranging from steatosis to steatohepatitis and liver fibrosis.

    This report describes a patient not suspected of having Klinefelter syndrome during life but diagnosed with it following postmortem examination using fluorescent in situ hybridization (FISH) for sex chromosomes and hormone serum analysis. A 49-year-old Japanese man had a history of nephrosis, heavy alcohol consumption, diabetes mellitus, and liver cirrhosis and had been undergoing dialysis for 10 years. He died of ruptured esophageal varices. Autopsy revealed hypogonadism, suggesting Klinefelter syndrome. This was confirmed by FISH, which showed a mosaic 46XY, 47XXY karyotype, and by serum analysis, which revealed high luteinizing hormone and follicle-stimulating hormone and low testosterone levels. Autopsy also revealed a nodular, bilateral, testicular Leydig cell hyperplasia. This report illustrates the value of postmortem laboratory investigations, particularly FISH for sex chromosomes and serum hormone analysis, for the demonstration of clinically uncertain or "occult" Klinefelter syndrome.

    Hepatocellular adenoma is considered to occur exclusively in non-fibrotic livers. It is a heterogeneous entity and a molecular classification is now widely accepted. The most frequent hepatocellular adenoma subtype, namely inflammatory adenoma, harbor somatic activating mutations of genes involved in the interleukin-6 pathway that lead to high C-reactive protein and serum amyloid A expression. The aim of our study was to investigate a series of benign hepatocellular neoplasms developed on cirrhotic livers and characterized by an unequivocal histological diagnosis. We performed a clinical, pathological, and molecular study of 10 benign hepatocellular neoplasms developed in three patients with cirrhosis. Markers allowing hepatocellular adenoma classification were assessed by quantitative real-time PCR and immunohistochemistry. Samples were sequenced for CTNNB1, HNF1A, IL6ST, GNAS, STAT3, and TERT (promoter) mutations. A control series of 32 classical macronodules developed in cirrhosis related to various etiologies was screened by immunohistochemistry and gene sequencing. The three patients had cirrhosis related to metabolic syndrome and/or alcohol intake; two had a single tumor, while the third developed more than 30 lesions. Microscopic examination showed well-differentiated neoplasms sharing features with inflammatory adenoma including inflammatory infiltrates, sinusoidal dilatation, and dystrophic vessels. Sequencing revealed classical hotspot somatic mutations (IL6ST, n=8; STAT3, n=1; and GNAS, n=1) known to be responsible for IL-6/JAK/STAT pathway activation. Two classical high-grade macronodules demonstrated high serum amyloid A and/or C-reactive protein expression, without gene mutations. Altogether, our findings support the existence of rare inflammatory adenoma developed in cirrhosis.

    Alcoholic liver disease (ALD) is a leading cause of liver disease and liver-related deaths globally, particularly in developed nations. Liver fibrosis is a consequence of ALD and other chronic liver insults, which can progress to cirrhosis and hepatocellular carcinoma if left untreated. Liver fibrosis is characterized by accumulation of excess extracellular matrix components, including type Ⅰ collagen, which disrupts liver microcirculation and leads to injury. To date, there is no therapy for the treatment of liver fibrosis; thus treatments that either prevent the accumulation of type Ⅰ collagen or hasten its degradation are desirable. The focus of this review is to examine the regulation of type Ⅰ collagen in fibrogenic cells of the liver and to discuss current advances in therapeutics to eliminate excessive collagen deposition.

    AIM: To study whether CCR5△32 mutation was associated with viral infection and severity of liver disease.METHODS: Two hundred and fifty two histologically proven, chronic HCV patients (mean age: 41 ± 14 years;M/F: 164/88) were genotyped. PCR based genotyping of 32 bp deletion at the CCR5 locus was done. Fourhundred and eight matched healthy controls were studied to assess susceptibility to HCV infection. To assess correlation of immune gene polymorphism with severity of HCV related liver disease, patients with chronic HCV infection were divided into those with a fibrosis score of ≤ 2 (mild) or > 2 (severe) and histological activity index (HAI) of ≤ 5 or > 5. For correlation between CCR5△32 mutations and response to therapy, 129 patients who completed therapy were evaluated.RESULTS: The majority (89.4%) of the patients were infected with genotype 3. The frequency of homozygous CCR5△32 mutants was comparable to HCV patients as compared to the healthy controls (0.7% vs 0%, P = 0.1).Further more, the frequency of CCR5△32 mutation was comparable in patients with mild or severe liver disease.(P = NS). There was also no association observed with response to therapy and CCR5△32 mutation.CONCLUSION: CCR5△32 mutation does not have a role in disease susceptibility, severity or response to therapy in patients with chronic hepatitis C infection.

    Objective To evaluate the effects of functional analysis of hepatic asialoglycoprotein receptors (ASGPR) for differentiating diseased liver from the normal ones in vitro and in vivo. Methods The rat model of chronic liver disease was established with inhaling CCl4.Galactosylneoglycoalbumin (NGA) was labeled with fluorescien isothiocyanate (FITC) by Marshal's method, or was labeled directly with Na99TcmO4 by SnCl2 method. The ASGPR on hepatocytes was analyzed by flow cytometry method (FCM) in vitro and by SPECT in vivo. Results It was showed that the amounts of ASGPR on normal and injured hepatocytes were very different in vitro. The worse the hepatocytes were injured, the lower the mean intensity of fluorescein (MIF) would be detected.Biodistribution analysis in animals showed that 99 Tcm-NGA could be uptaken fast by liver, no significant accumulation in other organs was obtained. Intestinal accumulation was also minimal and increased with time, that indicated the major excretory route of 99 Tcm-NGA was the biliary system and, eventually, the gastrointestinal tract. The blood clearance was fast in normal animals but retarded in liver injured model animals. The simple kinetics analysis indicated that radioactivity curves overtime of both hearts and livers in normal animals were obviously different from those in model animals. The receptor indexes (LHL15) were 0.980±0.010 and 0.949±0.025, and the clearance indexes (HH15) were 0.675±0.106 and 0.696±0.103 respectively. Conclusions The FCM is a good method for analyzing the amount of ASGPR on the surface of normal and injured heptocytes in vitro. Hepatic imaging using 99 Tcm-NGA can reflect specific hepatocyte function as the radioligand is metabolized only by the ASGPR on hepatocytes. As hepatic uptake of 99 Tcm-NGA and LHL15 analysis is sensitive for quantitation of ASGPR , fairly good estimation of liver function in liver disease is possible based on visual 99 Tcm-NGA imaging of the liver alone

  5. Cytokines and Liver Diseases

    2001-01-01

    Full Text Available Cytokines are pleiotropic peptides produced by virtually every nucleated cell in the body. In most tissues, including the liver, constitutive production of cytokines is absent or minimal. There is increasing evidence that several cytokines mediate hepatic inflammation, apoptosis and necrosis of liver cells, cholestasis and fibrosis. Interestingly, the same mediators also mediate the regeneration of liver tissue after injury. Among the various cytokines, the proinflammatory cytokine tumour necrosis factor-alpha (TNF-a has emerged as a key factor in various aspects of liver disease, such as cachexia and/or cholestasis. Thus, antagonism of TNF-a and other injury-related cytokines in liver diseases merits evaluation as a treatment of these diseases. However, because the same cytokines are also necessary for the regeneration of the tissue after the liver has been injured, inhibition of these mediators might impair hepatic recovery. The near future will bring the exiting clinical challenge of testing new anticytokine strategies in various liver diseases.

    Three patients with hepatitis C virus (HCV)-related chronic liver disease were shown to have autoantibodies strongly reacting with cytoskeletal fibres of non-muscle cells. The heavy chain of non-muscle myosin microfilament was the main target for those autoantibodies, as determined by (i) cell and tissue immunofluorescence studies showing colocalization with an anti-myosin antibody prototype; (ii) primary reactivity in immunoblotting with a 200-kD protein, using either MOLT-4 cells, human platelets, or affinity-purified non-muscle myosin as antigen extract; and (iii) immunoblotting of similar immunoreactive fragments in papain-digested MOLT-4 cell extracts, by using those human sera and antibody prototype. Autoantibodies to non-muscle myosin heavy chain were not previously reported in patients with chronic liver diseases, especially in those associated with HCV infection.

    2016-12-01

    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.

    Full Text Available Chronic granulomatous disease (CGD is a primary immune deficiency causing predisposition to infections with specific microorganisms, Aspergillus species and Staphylococcus aureus being the most common ones. A 16-year-old boy with a mutation in CYBB gene coding gp91phox protein (X-linked disease developed a liver abscess due to Staphylococcus aureus. In addition to medical therapy, surgical treatment was necessary for the management of the disease. A 30-month-old girl with an autosomal recessive form of chronic granulomatous disease (CYBA gene mutation affecting p22phox protein had invasive aspergillosis causing pericarditis, pulmonary abscess, and central nervous system involvement. The devastating course of disease regardless of the mutation emphasizes the importance of early diagnosis and intervention of hematopoietic stem cell transplantation as soon as possible in children with CGD.

    Propranolol is known to decrease portal pressure by reducing blood flow of portal vein. Per-rectal portal scintigraphy with Tc-99m pertechnetate has been introduced to evaluate the portal circulation and early diagnosis of liver cirrhosis. We evaluated the effects of propranolol on portal circulation by using per-rectal portal scintigraphy. We analyzed the portal hemodynamics by per-rectal portal scintigraphy in 51 patients with liver cirrhosis, 10 chronic hepatitis and 10 normal subjects. 38 patients with cirrhosis underwent per-rectal portal scintigraphy before and after propranolol medication. Per-rectal portal scintigraphy was performed after per-rectal administration of 370 MBq of Tc-99m pertechnetate. The shunt index was calculated as the ratio, expressed as a percentage of heart radioactivity to the sum of heart and liver radioactivity during the first 30 seconds. The shunt index in 40 patients with cirrhosis (59.8{+-}27.2%) was significantly higher than that of normal control (5.0{+-}1.2%, p<0.01) and chronic hepatitis (11.4{+-}3.5%, p<0.01). Shunt index was significantly different according to Child's classification and the degree of esophgageal varix (p<0.01). After propranolol medication, shunt index was significantly decreased from 59.9{+-}27.3% to 51.3{+-}15.3% (p<0.01) in 38 patients with liver cirrhosis. There was no significant difference of the amount of shunt index reduction after propranolol according to Child's classification and the degree of esophageal varix. The effect of propranolol on portal circulation was demonstrated as decreasing shunt index on per-rectal portal scintigraphy in patients with liver cirrhosis. Per-rectal portal scintigraphy may be useful to evaluate the portal circulation and to predict the effect of propranolol in patients with liver cirrhosis.

    AIM: To estimate the prevalence and identify the risk factors for metabolic bone disease in patients with cirrhosis. METHODS: The study was performed on 72 Indian patients with cirrhosis (63 male, 9 female; aged < 50 years). Etiology of cirrhosis was alcoholism ( n = 37), hepatitis B ( n = 25) and hepatitis C ( n = 10). Twenty-three patients belonged to Child class A, while 39 were in class B and 10 in class C. Secondary causes for metabolic bone disease and osteoporosis were ruled out. Sunlight exposure, physical activity and dietary constituents were calculated. Complete metabolic profiles were derived, and bone mineral density (BMD) was measured using dual energy X ray absorptiometry. Low BMD was defined as a Z score below -2. RESULTS: Low BMD was found in 68% of patients. Lumbar spine was the most frequently and severely affected site. Risk factors for low BMD included low physical activity, decreased sunlight exposure, and low lean body mass. Calcium intake was adequate, with unfavorable calcium: protein ratio and calcium: phosphorus ratio. Vitamin D deficiency was highly prevalent (92%). There was a high incidence of hypogonadism (41%). Serum estradiol level was elevated significantly in patients with normal BMD. Insulin-like growth factor (IGF) 1 and IGF binding protein 3 levels were below the age-related normal range in both groups. IGF-1 was significantly lower in patients with low BMD. Serum osteocalcin level was low (68%) and urinary deoxypyridinoline to creatinine ratio was high (79%), which demonstrated low bone formation with high resorption. CONCLUSION: Patients with cirrhosis have low BMD. Contributory factors are reduced physical activity, low lean body mass, vitamin D deficiency and hypogonadism and low IGF-1 level.

    Scintigraphy with {sup 99m}Tc-diethylenetriaminepentaacetate with galactosyl human serum albumin ({sup 99m}Tc-GSA) and per-rectal portal scintigraphy are useful for evaluating hepatic functional reserve and portal circulation, respectively. We did the procedures simultaneously in some patients to examine the relationship between hepatic functional reserve and portal circulation in chronic liver disease. Scintigraphy with {sup 99m}Tc-GSA was done in 10 healthy subjects, 45 patients with chronic hepatitis, and 165 patients with cirrhosis. Fifty-seven patients (13 with hepatitis and 44 with cirrhosis) also underwent per-rectal portal scintigraphy with {sup 99m}Tc-pertechnetate within two weeks. A receptor index was calculated by dividing the radioactivity of the liver region of interest (ROI) by that of the liver-plus-heart ROI at 15 min after the injection of {sup 99m}Tc-GSA. The index of blood clearance was calculated by dividing the radioactivity of the heart ROI at 15 min by that of the heart ROI at 3 min. A solution containing {sup 99m}Tc-pertechnetate was instilled into the rectum, and serial scintigrams were taken while radioactivity curves for the liver and heart were recorded sequentially. A per-rectal portal shunt index was determined by calculating the ratio of counts for the liver to counts for the heart integrated for 24 seconds immediately after the appearance of the liver time-activity curve. The median receptor index was lower for more severe liver disorders, increasing in the order of chronic hepatitis, compensated cirrhosis and decompensated cirrhosis, and the median index of blood clearance was higher. The median receptor index was significantly lower when a complication (varices, ascites, or encephalopathy) was present, and the median index of blood clearance was higher. The shunt index was correlated significantly with the two other indices, but these values for some one-third of the patients disagreed in either indices. Scintigraphy with {sup 99m

    Full Text Available Background: The presence of anti-HBc IgG in the absence of HBsAg is usually indicative of a past self-limiting HBV infection. But it is frequently associated with co-infection with HCV which can worsen the existing status of chronic liver disease (CLD. Objectives: The present study was planned to evaluate the significance of isolated HBc IgG positivity in patients of CLD and look for the presence of HCV co-infection in such patients. Methods: Clinical profiles and biochemical tests were done for all the 77 CLD cases included in the study. Blood samples were taken from these patients and tested by the commercially available EIA for the presence of HBsAg, anti-HBc IgG, anti-HBs and anti-HCV. HBV DNA was detected by amplifying the surface region in all the cases. Results: Isolated anti-HBc IgG positivity defined as the presence of anti-HBc IgG in absence of any other serological markers of HBV infection was detected in 28 patients . Out of 64 patients positive for anti-HBc IgG 36 had the markers of HBV, either HBsAg, HBV DNA or anti-HBs alone or in combination. There was a significant association between isolated anti-HBc IgG positivity and HCV co-infection. Conclusion: Anti-HBc IgG should be tested in all patients with CLD as it is frequently the only marker of HBV infection in such patients and they should be monitored closely as such patients can develop CLD. Presence of co-infection with HCV should be actively searched for in such patients.

    Several studies revealed that gut microbiota are associated with various human diseases, e.g., metabolic diseases, allergies, gastroenterological diseases, and liver diseases. The liver can be greatly affected by changes in gut microbiota due to the entry of gut bacteria or their metabolites into the liver through the portal vein, and the liver-gut axis is important to understand the pathophysiology of several liver diseases, especially non-alcoholic fatty liver disease and hepatic encephalopathy. Moreover, gut microbiota play a significant role in the development of alcoholic liver disease and hepatocarcinogenesis. Based on these previous findings, trials using probiotics have been performed for the prevention or treatment of liver diseases. In this review, we summarize the current understanding of the changes in gut microbiota associated with various liver diseases, and we describe the therapeutic trials of probiotics for those diseases.

    Primary biliary cirrhosis (PBC), primary sclerosing cholangitis (PSC) and autoimmune hepatitis (AIH) constitute the classic autoimmune liver diseases (AILDs). While AIH target the hepatocytes, in PBC and PSC the targets of the autoimmune attack are the biliary epithelial cells. Persistent liver injury, associated with chronic AILD, leads to un-resolving inflammation, cell proliferation and the deposition of extracellular matrix proteins by hepatic stellate cells and portal myofibroblasts. Liver cirrhosis, and the resultant loss of normal liver function, inevitably ensues. Patients with cirrhosis have higher risks or morbidity and mortality, and that in the decompensated phase, complications of portal hypertension and/or liver dysfunction lead to rapid deterioration. Accurate diagnosis and monitoring of cirrhosis is, therefore of upmost importance. Liver biopsy is currently the gold standard technique, but highly promising non-invasive methodology is under development. Liver transplantation (LT) is an effective therapeutic option for the management of end-stage liver disease secondary to AIH, PBC and PSC. LT is indicated for AILD patients who have progressed to end-stage chronic liver disease or developed intractable symptoms or hepatic malignancy; in addition, LT may also be indicated for patients presenting with acute liver disease due to AIH who do not respond to steroids.

    2016-04-14

    Non-alcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in developed countries and it is now considered a risk factor for cardiovascular disease. Evidence linking NAFLD to the development and progression of chronic kidney disease (CKD) is emerging as a popular area of scientific interest. The rise in simultaneous liver-kidney transplantation as well as the significant cost associated with the presence of chronic kidney disease in the NAFLD population make this entity a worthwhile target for screening and therapeutic intervention. While several cross-sectional and case control studies have been published to substantiate these theories, very little data exists on the underlying cause of NAFLD and CKD. In this review, we will discuss the most recent publications on the diagnosis of NAFLD as well new evidence regarding the pathophysiology of NAFLD and CKD as an inflammatory disorder. These mechanisms include the role of obesity, the renin-angiotensin system, and dysregulation of fructose metabolism and lipogenesis in the development of both disorders. Further investigation of these pathways may lead to novel therapies that aim to target the NAFLD and CKD. However, more prospective studies that include information on both renal and liver histology will be necessary in order to understand the relationship between these diseases.

    The possible link between nonalcoholic fatty liver disease and chronic kidney disease (CKD) recently has attracted considerable scientific interest. Accumulating clinical evidence indicates that the presence and severity of nonalcoholic fatty liver disease is associated significantly with CKD (defined as decreased estimated glomerular filtration rate and/or proteinuria) and that nonalcoholic fatty liver disease predicts the development and progression of CKD, independently of traditional cardiorenal risk factors. Experimental evidence also suggests that nonalcoholic fatty liver disease itself may exacerbate systemic and hepatic insulin resistance, cause atherogenic dyslipidemia, and release a variety of proinflammatory, procoagulant, pro-oxidant, and profibrogenic mediators that play important roles in the development and progression of CKD. However, despite the growing evidence linking nonalcoholic fatty liver disease with CKD, it has not been definitively established whether a causal association exists. The clinical implication for these findings is that patients with nonalcoholic fatty liver disease may benefit from more intensive surveillance or early treatment interventions to decrease the risk of CKD. In this review, we discuss the evidence linking nonalcoholic fatty liver disease with CKD and the putative mechanisms by which nonalcoholic fatty liver disease contributes to kidney damage. We also briefly discuss current treatment options for this increasingly prevalent disease that is likely to have an important future impact on the global burden of disease.

    Full Text Available Chronic alcohol abuse causes liver disease that progresses from simple steatosis through stages of steatohepatitis, fibrosis, cirrhosis, and eventually hepatic failure. In addition, chronic alcoholic liver disease (ALD, with or without cirrhosis, increases risk for hepatocellular carcinoma (HCC. Acetaldehyde, a major toxic metabolite, is one of the principal culprits mediating fibrogenic and mutagenic effects of alcohol in the liver. Mechanistically, acetaldehyde promotes adduct formation, leading to functional impairments of key proteins, including enzymes, as well as DNA damage, which promotes mutagenesis. Why certain individuals who heavily abuse alcohol, develop HCC (7.2–15% versus cirrhosis (15–20% is not known, but genetics and co-existing viral infection are considered pathogenic factors. Moreover, adverse effects of acetaldehyde on the cardiovascular and hematologic systems leading to ischemia, heart failure, and coagulation disorders, can exacerbate hepatic injury and increase risk for liver failure. Herein, we review the role of acetaldehyde adducts in the pathogenesis of chronic ALD and HCC.

    Full Text Available Abstract Background Patients with end-stage renal disease (ESRD are at a higher risk for chronic hepatitis, liver cirrhosis (LC and mortality than the general population. Optimal modalities of renal replacement therapy for ESRD patients with concomitant end-stage liver disease remain controversial. We investigated the long-term outcome for chronic liver disease among dialysis patients in an endemic area. Methods Using Taiwan’s National Health Insurance claim data (NHRI-NHIRD-99182, We performed a longitudinal cohort study to investigate the impact of comorbidities on mortality in dialysis patients. We followed up 11293 incident hemodialysis (HD and 761 peritoneal dialysis (PD patients from the start of dialysis until the date of death or the end of database period (December 31, 2008. A Cox proportional hazards model was used to identify the risk factors for all-cause mortality. Results Patients receiving PD tended to be younger and less likely to have comorbidities than those receiving HD. At the beginning of dialysis, a high prevalence rate (6.16 % of LC was found. Other than well-known risk factors, LC (hazard ratio [HR] 1.473, 95 % CI: 1.329-1.634 and dementia (HR 1.376, 95 % CI: 1.083-1.750 were also independent predictors of mortality. Hypertension and mortality were inversely associated. Dialysis modality and three individual comorbidities (diabetes mellitus, chronic lung disease, and dementia interacted significantly on mortality risk. Conclusions LC is an important predictor of mortality; however, the effect on mortality was not different between HD and PD patients.

    Notwithstanding numerous evidences implicating toll-like receptor-4 (TLR4) in the pathogenesis of chronic hepatitis C virus (HCV) infection, the localization and level of TLR4 expression in the liver of patients with hepatitis C have never been investigated. We aimed to evaluate, by means of immunohistochemistry and real-time PCR (rt-PCR), hepatic TLR4 expression in patients with chronic HCV infection. Fifty patients who had undergone liver biopsy and 11 patients transplanted because of chronic HCV infection, and 12 controls free of liver disease, were included in the study. Each case was analyzed by immunohistochemistry for TLR4, α-smooth muscle actin and cytokeratin-7 (CK-7), and a subgroup of patients and all controls by rt-PCR for TLR4. Immunohistochemistry for α-smooth muscle actin was used to derive a score of activation of hepatic stellate cells and portal/septal myofibroblasts, while immunohistochemistry for CK-7 was used to evaluate and count hepatic progenitor cells, interlobular bile ducts and intermediate hepatocytes. In patients, the parenchymal elements responsible for the highest TLR4 level of expression were hepatic progenitor cells and biliary epithelial cells of interlobular bile ducts. Double-labeling experiments between anti-TLR4 and anti-CK7, anti-CD133, anti-CD44, anti-neural cell adhesion molecule, anti-epithelial cell adhesion molecule and anti-sex determining region Y-box 9, confirmed these findings. TLR4-positive hepatic progenitor cells and interlobular bile ducts were significantly correlated with the stage of liver disease (PHCV-related infection.

    Our study aims to investigate the expression signature of plasma microRNA-106b (miRNA-106b, miR-106b) in hepatocellular carcinoma (HCC) patients and chronic liver disease (CLD) patients compared with healthy controls and further evaluate the potential clinical value of miR-106b as biomarker in HCC detection. In addition, a meta-analysis was conducted to assess the diagnostic performance of miR-106a/b as a biochemical marker for cancer screening. This study was divided into two phases. In the first phase, the expression levels of plasma miR-106b obtained from 108 subjects (47 HCC patients, 25 CLD patients, and 36 healthy controls) were measured by using qRT-PCR. Areas under receiver operating characteristic (ROC) curves (AUCs) were used to evaluate the diagnostic accuracy of plasma miR-106. In the second phase, a meta-analysis based on 11 previous researches as well as our current study was conducted to assess the potential clinical value of miR-106 in cancer detection. Plasma levels of miR-106b in HCC patients were significantly higher compared with CLD patients and healthy individuals. ROC curves suggested that plasma miR-106b yielded relative high sensitivities and specificities in differentiating HCC patients from CLD patients or healthy controls with corresponding AUC values of 0.726 and 0.879, respectively. In addition, miR-106b showed a relatively high accuracy in distinguishing CLD patients from healthy controls with its AUC value of 0.703. Furthermore, the meta-analysis for diagnostic performance of miR-106a/b showed a pooled sensitivity of 0.74, specificity of 0.75, and an AUC of 0.81. Subgroup analysis based on samples types revealed a higher diagnostic performance of miR-106 for cancer detection by using non-blood samples. Similarly, miR-106 as biomarker showed a higher diagnostic accuracy for gastric cancer detection. We found that plasma miR-106b has clinical value in the detection of HCC from healthy people and CLD patients. Further large-scale study

    The liver fibrosis is closely related to the diagnosis and treatment of chronic liver diseases. Early diagnosis of liver fibrosis might help patients with compensated liver functions slow down to the decompensated period,and also reduce the incidence of hepatocellular carcinoma. Liver biopsy is considered as the gold standard to assess the extent of liver damage in patients with chronic liver disease,but it is invasive. Transient elastography is a relatively novel,safe,noninvasive technique to evaluate liver stiffness. It can not only monitor the progression of liver fibrosis dynamically,but also objectively evaluate the liver damage. It is now widely used in clinic. In this review,the value of transient elastography in diagnosis of liver fibrosis was discussed.%肝脏纤维化程度及进展与慢性肝脏疾病的诊断与治疗密切相关。早期诊断肝纤维化程度有助于避免代偿期患者向肝硬化失代偿期发展,也有助于降低肝细胞癌的发生率。目前,临床上评估肝纤维化程度的“金标准”仍为肝脏穿刺活检,但是由于其操作的有创性,以及穿刺后可能出现的多种并发症等多种因素的影响,限制了它在临床研究中的使用。瞬时弹性成像技术无创、安全、有利于动态监测肝纤维化进展、客观评价肝脏纤维化程度,使其在国内外得到了广泛的认同,在临床上具有良好的应用前景。

    The levels of retinol-binding protein 4 (RBP4) - the carrier protein for Vitamin A in plasma - are tightly regulated under healthy circumstances. The kidney, the main site of RBP4 catabolism, contributes to an elevation of RBP4 levels during chronic kidney disease (CKD) whereas during chronic liver...... disease (CLD) RBP4 levels decrease. Little is known about RBP4 isoforms including apo-RBP4, holo-RBP4 as well as RBP4 truncated at the C-terminus (RBP4-L and RBP4-LL) except that RBP4 isoforms have been reported to be increased in hemodialysis patients.

    2011-01-01

    Full Text Available Background: Lamivudine and artesunate are sometimes co administered in HIV-malaria co morbidity. Both drugs are used concurrently in presumptive malaria treatment and simultaneous HIV post exposure prophylaxis. Aim: The aim of this study was to investigate the effect of lamivudine-artesunate co administration on the histology of the liver of diseased adult Wistar rats. Materials and Methods: Five groups of rats of both sexes were used for the study and placed on feed and water ad libitum. Disease state consisted of immunosuppression with cyclophosphamide, and infection with Plasmodium berghei. Group 1 animals served as vehicle control, while group 2 were the diseased controls. Group 3 animals received 20 mg/kg lamivudine for three weeks, while group 4 similarly received 20 mg/kg Lamivudine but also received 10 mg/kg artesunate from day 12. Animals in group 5 received 10 mg/kg artesunate from day 12. All drugs were administered intraperitoneally. The animals were treated for twenty-one days, at the end of which they were sacrificed and their livers fixed in 10% formalin for histological studies. Result: Results from the study show the presence of regions of focal necrosis and perivascular cuffing with animals that received artesunate. Hemosiderosis was a common feature in all the parasitized groups, while fatty degeneration was observed in the group that received artesunate alone. Conclusion: Concurrent lamivudine-artesunate administration resulted in some histopathological changes in the liver. This study suggests there may be considerable histological changes with repeated occurrence of malaria and immunosuppression that may warrant intermittent lamivudine-artesunate administration, and may require evaluation as well as monitoring of liver function during such therapeutic interventions.

    Nonalcoholic steatohepatitis (NASH) may account for many cases of cryptogenic cirrhosis. If so, then steatosis might recur after liver transplantation. Two thousand fifty-two patients underwent primary liver transplantation for chronic liver disease between 1986 and 2004. Serial liver biopsy samples were assessed for steatosis and fibrosis. Two hundred fifty-seven patients (12%) had a pretransplant diagnosis of cryptogenic cirrhosis (239) or NASH (18). Fatty liver developed in 31% and was more common when the pretransplant diagnosis was NASH (45% at 5 years versus 23% for cryptogenic cirrhosis, P = 0.007). NASH developed in only 4% and occurred exclusively when steatosis had already occurred. Steatosis after liver transplantation was associated with the baseline body weight and body mass index by univariate analyses, but no pretransplant or posttransplant characteristic independently predicted steatosis after liver transplantation because obesity was so common in all groups. Five percent and 10% developed bridging fibrosis or cirrhosis after 5 and 10 years, respectively, and this was more common after NASH (31%) than in those who developed steatosis alone (6%) or had no fat (3%, P = 0.002). One-, 5-, and 10-year survival was the same in patients who underwent transplantation for cryptogenic cirrhosis or NASH (86%, 71%, and 56%) and in patients who underwent transplantation for other indications (86%, 71%, and 53%; not significant), but death was more often due to cardiovascular disease and less likely from recurrent liver disease. In conclusion, fatty liver is common after liver transplantation for cryptogenic cirrhosis or NASH but is twice as common in the latter group; this suggests that some cryptogenic cirrhosis, but perhaps not all, is caused by NASH. Posttransplant NASH is unusual, and steatosis appears to be a prerequisite. Advanced fibrosis is uncommon, and survival is the same as that of patients who undergo transplantation for other causes.

  5. Pharmacokinetics in patients with chronic liver disease and hepatic safety of incretin-based therapies for the management of type 2 diabetes mellitus.

    2014-09-01

    Patients with type 2 diabetes mellitus have an increased risk of chronic liver disease (CLD) such as non-alcoholic fatty liver disease and steatohepatitis, and about one-third of cirrhotic patients have diabetes. However, the use of several antidiabetic agents, such as metformin and sulphonylureas, may be a concern in case of hepatic impairment (HI). New glucose-lowering agents targeting the incretin system are increasingly used for the management of type 2 diabetes. Incretin-based therapies comprise oral inhibitors of dipeptidyl peptidase-4 (DPP-4) (gliptins) or injectable glucagon-like peptide-1 (GLP-1) receptor agonists. This narrative review summarises the available data regarding the use of both incretin-based therapies in patients with HI. In contrast to old glucose-lowering agents, they were evaluated in specifically designed acute pharmacokinetic studies in patients with various degrees of HI and their hepatic safety was carefully analysed in large clinical trials. Only mild changes in pharmacokinetic characteristics of DPP-4 inhibitors were observed in patients with different degrees of HI, presumably without major clinical relevance. GLP-1 receptor agonists have a renal excretion rather than liver metabolism. Specific pharmacokinetic data in patients with HI are only available for liraglutide. No significant changes in liver enzymes were reported with DPP-4 inhibitors or GLP-1 receptor agonists, alone or in combination with various other glucose-lowering agents, in clinical trials up to 2 years in length. On the contrary, preliminary data suggested that incretin-based therapies may be beneficial in patients with CLD, more particularly in the presence of non-alcoholic fatty liver disease. Nevertheless, caution should be recommended, especially in patients with advanced cirrhosis, because of a lack of clinical experience with incretin-based therapies in these vulnerable patients.

    Full Text Available In recent years, significant progress has been made in furthering our knowledge of chronic liver disease (CLD and evaluating the therapeutic approaches. These have been updated in the form of recommendations by international scientific societies. Through a retrospective analysis, this study aimed to verify whether these recommendations have been applied in real practice. The study design included data gathered from all patients consecutively hospitalized for decompensated liver cirrhosis during one year. A pre-made master form was used to record data on the patients’ past knowledge of the etiology and management of their liver disease. As expected, hepatitis C virus (HCV was the most frequent cause of CLD, while 41 cases were cryptogenic. In 69 of 263 patients with HCV infection, viral genotyping had been performed, although only 39 of these cases had been treated. Only 3 of 44 patients suffering from hepatitis B virus (HBV-related liver cirrhosis had been treated in the past, while 11 patients were still being treated. Among the remaining patients, 15 were not aware that they had CLD and 15 had never been considered for antiviral treatment. In 81 cases, the disease had progressed to hepatocellular carcinoma, but only 19 patients had discovered the tumor following regular ultrasound screening. Thirty-seven patients were receiving specific treatment consistent with the stage of their disease. The management of HBV- and HCV-related CLD in Sicily is far from optimal, and although the natural history and management practices of these diseases are well known, this knowledge is a long way from being applied in our daily practice.

    AIM: To evaluate and compare the clinical usefulness of 13C-phenylalanine and 13C-methacetin breath tests in quantitating functional hepatic mass in patients with chronic liver disease and to further compare these results with those of conventional tests, Child-Pugh score and serum bile acid levels.METHODS: One hundred and forty patients (50 HCV-related chronic hepatitis, 90 liver cirrhosis patients) and 40 matched healthy controls were studied. Both breath test and routine liver test, serum levels of cholic and chenodeoxycholic acid conjugates were evaluated.RESULTS: Methacetin breath test, expressed as 60 min cumulative percent of oxidation, discriminated the hepatic functional capacity not only between controls and liver disease patients, but also between different categories of chronic liver disease patients. Methacetin breath test was correlated with liver function tests and serum bile acids.Furthermore, methacetin breath test, as well as serum bile acids, were highly predictive of Child-Pugh scores. The diagnostic power of phenylalanine breath test was always less than that of methacetin breath test.CONCLUSION: Methacetin breath test represents a safe and accurate diagnostic tool in the evaluation of hepatic functional mass in chronic liver disease patients.

    Childhood obesity has reached epidemic proportions, and by 2012, more than one third of American children were overweight or obese. As a result, increasingly, children are developing complications of obesity including liver disease. In fact, non-alcoholic fatty liver disease is the most common form of chronic liver disease seen in children today. Recently, there has been a burgeoning literature examining the pathogenesis, genetic markers, and role of the microbiome in this disease. On the clinical front, new modalities of diagnosing hepatic steatosis and hepatic fibrosis are being developed to provide non-invasive methods of surveillance in children. Lastly, the mainstay of treatment of pediatric non-alcoholic fatty liver disease (NAFLD) has been largely through lifestyle interventions, namely, dieting and exercise. Currently, there are a number of clinical trials examining novel lifestyle and drug therapies for NAFLD that are registered with the US National Institutes of Health ClinicalTrials.gov website.

  9. Role of Gut Microbiota in Liver Disease.

    2015-01-01

    Many lines of research have established a relationship between the gut microbiome and patients with liver disease. For example, patients with cirrhosis have increased bacteremia, increased blood levels of lipopolysaccharide, and increased intestinal permeability. Patients with cirrhosis have bacterial overgrowth in the small intestine. Selective intestinal decontamination with antibiotics is beneficial for patients with decompensated cirrhosis. In experimental models of chronic liver injury with fibrosis, several toll-like receptors (TLR) are required to make mice sensitive to liver fibrosis. The presumed ligand for the TLRs are bacterial products derived from the gut microbiome, and TLR knockout mice are resistant to liver inflammation and fibrosis. We and others have characterized the association between preclinical models of liver disease in mice with the microbial diversity in their gut microbiome. In each model, including intragastric alcohol, bile duct ligation, chronic carbon tetrachloride (CCl4), administration, and genetic obesity, there is a significant change in the gut microbiome from normal control mice. However, there is not a single clear bacterial strain or pattern that distinguish mice with liver injury from controlled mice. So how can the gut microbiota affect liver disease? We can identify at least 6 changes that would result in liver injury, inflammation, and/or fibrosis. These include: (1) changes in caloric yield of diet; (2) regulation of gut permeability to release bacterial products; (3) modulation of choline metabolism; (4) production of endogenous ethanol; (5) regulation of bile acid metabolism; and (6) regulation in lipid metabolism.

    A 77-year-old African American male presented with intermittent abdominal pain for one week. He denied nausea, vomiting, diarrhea, constipation, fevers, anorexia, or weight loss. He denied a family history of liver disease, recent travel, or history of intravenous drug abuse. His vital signs were normal. Labs revealed total bilirubin of 1.5 mg/dl, hypoalbuminaemia 3.0 gm/dl and prolonged prothrombin time of 14.8 sec. Computed Tomography of the abdomen and pelvis with contrast showed multiple hepatic cysts with the largest cyst occupying the right abdomen, measuring 20.6 cm (Panel A and). This cyst had predominantly fluid attenuation, but also contained several septations. The patient underwent laparoscopic fenestration of the large hepatic cyst with hepatic cyst wall biopsy. Pathology revealed blood without malignant cells. The patient tolerated the procedure well with improvement of his abdominal pain and normalization of his liver function tests and coagulation profile.

    Objective To analyze the diagnostic coincidence rate and impact factors of the detection cut-off value for the assessment of liver fibrosis by Transient Elastography ( Fibroscan) and clinical diagnosis in four different chronic liver diseases: chronic hepatitis B , chronic hepatitis C , hepatitis B cirrhosis and hepatitis C cirrhosis. Methods 1 458 patients with chronic liver diseases (446 patients with hepatitis C, 398 patients with hepatitis B, 176 patients with hepatitis C cirrhosis, 438 patients with hepatitis B cirrhosis) admitted to Tangdu Hospital from Apr. 2009to Jun. 2010 were measured to obtain cut-off value by Fibroscan. The diagnostic coincidence rate and impact factors were analyzed in these four groups of liver diseases. Results Liver stiffness measurement using Fibroscan was 12.4 KPa as the cut-off value. By contrast with the clinical diagnosis, the diagnostic coincidence rate of Fibroscan in patients with chronic hepatitis C , hepatitis B, cirrhotic patients with hepatitis C and hepatitis B were 94. 17% , 70. 60% , 85. 80% , 85. 39% , respectively. There was significantly different in the diagnostic rate between chronic hepatitis C and chronic hepatitis B. Liver stiffness measurement of 117 patients with chronic hepatitis B was out of accord with the clinical diagnosis, in which, 34 patients with BMI > 25 kg/m2, accounted for 29. 06% ; 74 patients of liver function ALT > 80 U/L, accounted for 63.25%. Conclusion Fibroscan is helpful to the diagnosis of chronic liver diseases, especially hepatitis C. Obesity and liver inflammation are important impact factors of the cut-off value. The right time and appropriate patients choosing are important to improve the accuracy of Fibroscan for diagnosis.%目的 分析瞬时弹性扫描仪(Fibroscan)在慢性乙型肝炎、慢性丙型肝炎、乙型肝炎肝硬化及丙型肝炎肝硬化四种不同慢性肝病中检测的cut-off值对肝纤维化测量的准确性及影响因素.方法 我院2009年4月- 2010

    A 16-year-old Hispanic girl with an elevated body mass index in an otherwise normal state of health presented for her well-child examination. She had signs of metabolic syndrome and insulin resistance including increased waist circumference and acanthosis nigricans. Laboratory results revealed elevated transaminases with otherwise normal hepatic function. Based on the physical examination and laboratory results, she was diagnosed with nonalcoholic fatty liver disease (NAFLD). After further evaluation, she eventually underwent a liver biopsy. The biopsy revealed nonalcoholic steatohepatitis (NASH) with stage 2 fibrosis. This article reviews the definition of NAFLD and NASH, an increasingly prevalent cause of pediatric chronic liver disease associated with obesity and metabolic syndrome. The article also outlines the epidemiology, risk factors, and natural history of NAFLD, which may help identify and prevent high-risk pediatric patients from progressing to irreversible liver disease. Understanding the diagnostic and treatment options offers the best chance at preventing and reversing the early stages of this disease.

    Full Text Available Background: Hepatic steatosis measured with controlled attenuation parameter (CAP using transient elastography predicts metabolic syndrome in the general population. We investigated whether CAP predicted metabolic syndrome in chronic kidney disease patients. Methods: CAP was measured with transient elastography in 465 predialysis chronic kidney disease patients (mean age, 57.5 years. Results: The median CAP value was 239 (202–274 dB/m. In 195 (41.9% patients with metabolic syndrome, diabetes mellitus was more prevalent (105 [53.8%] vs. 71 [26.3%], P < 0.001, with significantly increased urine albumin-to-creatinine ratio (184 [38–706] vs. 56 [16–408] mg/g Cr, P = 0.003, high sensitivity C-reactive protein levels (5.4 [1.4–28.2] vs. 1.7 [0.6–9.9] mg/L, P < 0.001, and CAP (248 [210–302] vs. 226 [196–259] dB/m, P < 0.001. In multiple linear regression analysis, CAP was independently related to body mass index (β = 0.742, P < 0.001, triglyceride levels (β = 2.034, P < 0.001, estimated glomerular filtration rate (β = 0.316, P = 0.001, serum albumin (β = 1.386, P < 0.001, alanine aminotransferase (β = 0.064, P = 0.029, and total bilirubin (β = −0.881, P = 0.009. In multiple logistic regression analysis, increased CAP was independently associated with increased metabolic syndrome risk (per 10 dB/m increase; odds ratio, 1.093; 95% confidence interval, 1.009–1.183; P = 0.029 even after adjusting for multiple confounding factors. Conclusion: Increased CAP measured with transient elastography significantly correlated with and could predict increased metabolic syndrome risk in chronic kidney disease patients.

    The transforming growth factor-beta (TGF-β) family signalling pathways play essential roles in the regulation of different cellular processes, including proliferation, differentiation, migration or cell death, which are essential for the homeostasis of tissues and organs. Because of the diverse and pleiotropic TGF-β functions, deregulation of its pathways contributes to human disease. In the case of the liver, TGF-β signalling participates in all stages of disease progression, from initial liver injury through inflammation and fibrosis, to cirrhosis and cancer. TGF-β has cytostatic and apoptotic effects in hepatocytes, promoting liver differentiation during embryogenesis and physiological liver regeneration. However, high levels of TGF-β, as a consequence of chronic liver damage, result in activation of stellate cells to myofibroblasts and massive hepatocyte cell death, which contributes to the promotion of liver fibrosis and later cirrhosis. During liver tumorigenesis, TGF-β may behave as a suppressor factor at early stages; however, there is strong evidence that overactivation of TGF-β signalling might contribute to later tumour progression, once cells escape from its cytostatic effects. For these reasons, targeting the TGF-β signalling pathway is being explored to counteract liver disease progression. In this review, we aim to shed light on the state-of-the-art in the signalling pathways induced by TGF-β that are involved in different stages of liver physiology and pathology.

    Objective To clarify the relationship between liver stiffness and nutritional status of patients with chronic liver disease.Methods Liver stiffness of 205 hospitalized chronic liver disease patients were measured by transient elastography (FibroScan), and these patients were divided into four groups with different stage of liver ifbrosis. Nutritional risk screening (NRS 2002) was applied to evaluate the nutrition risk of different groups of patients. Subjective global nutritional assessment (SGA) was used to determine the nutrition status of these patients. The relationship was analyzed with Spearman rank correlation.Results NRS 2002 screening showed that nutrition risk increased, nutrition status decreased when the liver ifbrosis stage was getting severe, and the values of grasping power (HG), the triceps skinfold thickness (TSF), upper-arm circumference (MAC), prealbumin (PA), albumin (ALB) and total lymphocyte count (TLC) also declined, these differences were signiifcant (P< 0.05). The liver stiffness values of cirrhotic patient with more nutrition risk were higher than those with less nutrition risk, whereas the same result wasn’t observed in hepatitis patients.Conclusions There was difference in nutrition status among chronic liver disease patients with different liver stiffness, and increased nutrition risk or malnutrition might relate to liver stiffness.%目的:明确肝脏弹性值与慢性肝病患者营养状况的相关性。方法采用瞬时弹性成像(FibroScan)评价205例慢性肝病患者的肝纤维化情况,根据FibroScan值将患者分为4个不同肝纤维化组别,应用营养风险筛查表(NRS 2002)对各组患者进行营养风险筛查,主观综合性营养评估(SGA)评价其营养不良状况,使用Spearman秩相关方法分析其相关性。结果应用NRS 2002筛查4组处于不同肝纤维阶段患者的营养风险,结果提示伴随肝纤维化程度逐渐加重,营养风险发生率增加,营养不

    A disease is suitable for screening if it is common, if the target population can be identified and reached and if both a good screening test and an effective therapy are available. Of the most common liver diseases only viral hepatitis and genetic hemochromatosis partially satisfy these conditions. Hepatitis C is common, the screening test is good and the therapy eliminates the virus in half of the cases, but problems arise in the definition of the target population. In fact generalized population screening is not endorsed by international guidelines,although some recommend screening immigrants from high prevalence countries. Opportunistic screening (case finding) of individuals with classic risk factors,such as transfusion before 1992 and drug addiction,is the most frequently used strategy, but there is disagreement whether prison inmates, individuals with a history of promiscuous or traumatic sex and health care workers should be screened. In a real practice setting the performance of opportunistic screening by general practitioners is low but can be ameliorated by training programs. Screening targeted to segments of the population or mass campaigns are expensive and therefore interventions should be aimed to improve opportunistic screening and the detection skills of general practitioners. Regarding genetic hemochromatosis there is insufficient evidence for population screening, but individual physicians can decide to screen racial groups with a high prevalence of the disease, such as people in early middle age and of northern European origin. In the other cases opportunistic screening of high risk individuals should be performed, with a high level of suspicion in case of unexplained liver disease, diabetes, juvenile artropathy, sexual dysfunction and skin pigmentation.

    Nonalcoholic fatty liver disease (NAFLD), defined as abnormal accumulation (> 5%) of hepatic triglyceride without excess alcohol intake, is the most common form of chronic liver disease in adults and children in the United States. NAFLD encompasses a spectrum of histologic findings including uncomplicated steatosis, steatosis with inflammation and steatohepatitis [nonalcoholic steatohepatitis (NASH)]; the latter can advance to cirrhosis and hepatocellular carcinoma. NASH is currently accepted as the hepatic manifestation of the set of cardiovascular risk factors collectively known as metabolic syndrome. In 1999 a system for histologic grading and staging for NASH was proposed; this was revised by the NASH Clinical Research Network in 2005 for the entire spectrum of lesions in NAFLD, including the lesions and patterns of pediatric NAFLD, and for application in clinical research trials. Diagnosis remains distinct from grade and stage. A recent European proposal separates steatosis from activity to derive a numeric diagnosis of NASH. Even though there have been promising advancements in non-invasive testing, these tests are not yet detailed enough to replace the full range of findings provided by liver biopsy evaluation. Limitations of biopsy are acknowledged, but liver biopsy remains the "gold standard" for diagnosis and determination of amounts of necroinflammatory activity, and location of fibrosis, as well as remodeling of the parenchyma in NASH. This review focuses on the specific histologic lesions of NAFLD and NASH, grading and staging, differential diagnoses to be considered, and the continuing role of the liver biopsy in this important liver disease.

    Nonalcoholic fatty liver disease (NAFLD) is one of the most important chronic liver diseases worldwide and has garnered increasing attention in recent decades. NAFLD is characterized by a wide range of liver changes, from simple steatosis to nonalcoholic steatohepatitis, cirrhosis, and hepatocellular carcinoma. The blurred pathogenesis of NAFLD is very complicated and involves lipid accumulation, insulin resistance, inflammation, and fibrogenesis. NAFLD is closely associated with complications such as obesity, diabetes, steatohepatitis, and liver fibrosis. During the progression of NAFLD, reactive oxygen species (ROS) are activated and induce oxidative stress. Recent attempts at establishing effective NAFLD therapy have identified potential micronutrient antioxidants that may reduce the accumulation of ROS and finally ameliorate the disease. In this review, we present the molecular mechanisms involved in the pathogenesis of NAFLD and introduce some dietary antioxidants that may be used to prevent or cure NAFLD, such as vitamin D, E, and astaxanthin.

    Fibropolycystic liver diseases are a group of associated congenital disorders that present most often in childhood. These disorders include congenital hepatic fibrosis, biliary hamartomas, autosomal dominant polycystic liver disease, choledochal cysts and Caroli disease. We present a discussion and illustrations of the embryology, genetics, anatomy, pathology, imaging approach and key imaging features that distinguish fibropolycystic liver disease in children. The pathogenesis of these disorders is believed to be abnormal development of the embryonic ductal plates, which ultimately form the liver and biliary systems. An understanding of the abnormal embryogenesis helps to explain the characteristic imaging features of these disorders. (orig.)

    Evidence from epidemiological studies suggests that a diet high in fiber is associated with better lung function and reduced risk of chronic obstructive pulmonary disease (COPD). The mechanism for this benefit remains unknown, but, as fiber is not absorbed by the gut, this finding suggests that the gut may play an active role in pathogenic pathways underlying COPD. There is a growing awareness that aberrant activity of the innate immune system, characterized by increased neutrophil and macrophage activation, may contribute to the development or progression of COPD. Innate immunity is modulated in large part by the liver, where hepatic cells function in immune surveillance of the portal circulation, as well as providing a rich source of systemic inflammatory cytokines and immune mediators (notably, IL-6 and C-reactive protein). We believe that the beneficial effect of dietary fiber on lung function is through modulation of innate immunity and subsequent attenuation of the pulmonary response to inflammatory stimuli, most apparent in current or former smokers. We propose that the "gut-liver-lung axis" may play a modifying role in the pathogenesis of COPD. In this review, we summarize lines of evidence that include animal models, large prospective observational studies, and clinical trials, supporting the hypothesis that the gut-liver-lung axis plays an integral part in the pathogenic mechanisms underlying the pathogenesis of COPD.

    Full Text Available Alcohol use disorders and alcohol dependency affect millions of individuals worldwide. The impact of these facts lies in the elevated social and economic costs. Alcoholic liver disease is caused by acute and chronic exposure to ethanol which promotes oxidative stress and inflammatory response. Chronic consumption of ethanol implies liver steatosis, which is the first morphological change in the liver, followed by liver fibrosis and cirrhosis. This review comprises a broad approach of alcohol use disorders, and a more specific assessment of the pathophysiologic molecular basis, and genetics, as well as clinical presentation and current modalities of treatment for alcoholic liver disease.

    Although Wilsons's disease (WD) may be treated with copper chelation (to remove copper) or zinc salts (to prevent absorption) to alleviate or prevent symptom development in most patients, there are WD patients for whom medical therapy is inadequate and survival would be unlikely without liver transplantation. Liver transplantation is indicated for the ∼5% of WD patients with acute liver failure as the first presentation of disease, most commonly in the second decade of life, or those who present with end-stage liver disease and severe hepatic insufficiency, most commonly in the third and fourth decades. Liver transplantation restores normal biliary copper excretion (thereby preventing disease recurrence) and promotes removal of copper from extrahepatic sites. Outcomes of liver transplantation for WD are excellent, including both cadaveric and living donors.

    Full Text Available Chronic hepatitis C virus (HCV infection still represents a major public health problem, as it is thought to be responsible for more than 350,000 deaths around the globe on a yearly basis. Fortunately, successful eradication of the virus has been associated with improved clinical outcome and reduced mortality rates. In the past few years, treatment has improved considerably by the implementation of direct-acting antivirals (DAAs. From 2014 onwards, sofosbuvir, simeprevir, daclatasvir, ledipasvir, paritaprevir, ombitasvir, and dasabuvir have been approved by the US Food and Drug Administration (FDA and European Medicines Agency (EMA. Regimens with various combinations of these new drugs, without the use of interferon (IFN, proved to be very effective and well tolerated, even among patients with advanced liver disease. Moreover, treatment duration could be shortened to 12 weeks in the majority of patients. The high costs of these DAAs, however, limit the availability of IFN-free therapy worldwide. Even in wealthy countries, it is deemed necessary to prioritize DAA treatment in order to limit the immediate impact on the health budget. As patients with advanced liver disease are in most need of HCV clearance, many countries decided to treat those patients first. In the current review, we focus on the currently available IFN-free treatment options for patients with cirrhosis. We discuss the virological efficacy as well as the clinical relevance of these regimens among this specific patient population.

    2015-07-01

    Non-alcoholic fatty liver disease is the most common chronic liver disease in Europe and in the USA with rising prevalence. Patients with a metabolic syndrome (diabetes mellitus, obesity, dyslipidemia) are patients at risk with the highest prevalence for NAFLD. Progression from a non-alcoholic fatty liver (NAFL) to a non-alcoholic steatohepatitis (NASH) occurs in 5-20% of patients with the potential to develop a liver fibrosis/cirrhosis. NASH patients and NAFLD patients with higher fibrosis should be identified because they are at risk of a higher mortality. A specific treatment for NASH is not available at the moment. Therefore, the treatment of risk factors and metabolic syndrome has high priority.

    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.

    Science.gov (United States)

    Sarin, Shiv K; Choudhury, Ashok

    2016-03-01

    Acute-on-chronic liver failure (ACLF) is a distinct clinical entity and differs from acute liver failure and decompensated cirrhosis in timing, presence of acute precipitant, course of disease and potential for unaided recovery. The definition involves outlining the acute and chronic insults to include a homogenous patient group with liver failure and an expected outcome in a specific timeframe. The pathophysiology of ACLF relates to persistent inflammation, immune dysregulation with initial wide-spread immune activation, a state of systematic inflammatory response syndrome and subsequent sepsis due to immune paresis. The disease severity and outcome can be predicted by both hepatic and extrahepatic organ failure(s). Clinical recovery is expected with the use of nucleoside analogues for hepatitis B, and steroids for severe alcoholic hepatitis and, possibly, severe autoimmune hepatitis. Artificial liver support systems help remove toxins and metabolites and serve as a bridge therapy before liver transplantation. Hepatic regeneration during ongoing liver failure, although challenging, is possible through the use of growth factors. Liver transplantation remains the definitive treatment with a good outcome. Pre-emptive antiviral agents for hepatitis B before chemotherapy to prevent viral reactivation and caution in using potentially hepatotoxic drugs can prevent the development of ACLF.

  20. The Use of Thrombopoietin Receptor Agonists for Correction of Thrombocytopenia prior to Elective Procedures in Chronic Liver Diseases: Review of Current Evidence

    Directory of Open Access Journals (Sweden)

    Kamran Qureshi

    2016-01-01

    Full Text Available Patients with chronic liver diseases (CLD undergo a range of invasive procedures during their clinical lifetime. Various hemostatic abnormalities are frequently identified during the periprocedural work-up; including thrombocytopenia. Thrombocytopenia of cirrhosis is multifactorial in origin, and decreased activity of thrombopoietin has been identified to be a major cause. Liver is an important site of thrombopoietin production and its levels are decreased in patients with cirrhosis. Severe thrombocytopenia (platelet counts < 60–75,000/µL is associated with increased risk of bleeding with invasive procedures. In recent years, compounds with thrombopoietin receptor agonist activity have been studied as therapeutic options to raise platelet counts in CLD. We reviewed the use of Eltrombopag, Romiplostim, and Avatrombopag prior to various invasive procedures in patients with CLD. These agents seem promising in raising platelet counts before elective procedures resulting in reduction in platelet transfusions, and they also enabled more patients to undergo the procedures. However, these studies were not primarily aimed at comparing bleeding episodes among groups. Use of these agents had some adverse consequences, importantly being the occurrence of portal vein thrombosis. This review highlights the need of further studies to identify reliable methods of safely reducing the provoked bleeding risk linked to thrombocytopenia in CLD.

    Full Text Available Aims: The present study evaluated the utility of xenon computed tomography (Xe-CT as a noninvasive diagnostic procedure for the measurement of hepatic tissue blood flow (TBF in patients with nonalcoholic fatty liver disease (NAFLD or chronic hepatitis C (CH-C. Methods: Xe-CT was performed in 93 patients with NAFLD and in 109 patients with CH-C. Subjects were classified into one of three groups, based on fibrosis stage: group 1, no bridging fibrosis; group 2, bridging fibrosis; and group 3, liver cirrhosis. Correlations between hepatic TBFs in each fibrosis stage were examined. Results: In group 1, portal venous TBF (PVTBF, hepatic arterial (HATBF, and total hepatic TBF (THTBF were significantly lower in patients with in nonalcoholic steatohepatitis (NASH than in those with CH-C (p < 0.001, p < 0.05, p < 0.001, respectively. In group 2, PVTBF and THTBF were significantly lower in patients with in NASH than in those with CH-C (p < 0.001, p < 0.05, respectively. In group 3, hepatic TBFs were not significantly different when comparing patients with NASH and those with CH-C. Conclusions: PVTBF decreased due to fat infiltration. Therefore, hemodynamic changes occur relatively earlier in NAFLD than in CH-C. Patients with NASH should be monitored carefully for portal hypertensive complications in the early fibrosis stage.

    Forty four patients with refractory ascites due to chronic liver diseases that fulfilling the inclusion criteria of selection were divided into 2 groups. The first group (GI, n=24) was subdivided into 2 subgroups according to degree of liver condition; GIa (n=11) with Child-Pugh class B and GIb (n=13) with early class C. The patients were subjected to P-V shunt (Denver group). Similarly, patients in the second group (GII, n=20) were divided into 2 subgroups GIIa (n=10) & GIIb (n=10) respectively and treated by the repeated tapping and albumin infusion (control group). Postoperative results revealed a significant increase in urine out put (P<0.001), decrease in abdominal girth (P<0.01) and body weight (p<0.01) with more patients fitness and satisfaction than in controls. Postoperative complications were more in GIb. Ascites recurrence occurred in 3 (23%) patients in GIb due to severe infection (2 cases) and irreversible shunt obstruction (1 case) and without recurrence in GIa. So, Denver P-V shunt offers a good palliation in such patients, but its use is more justified in selected cases.

    Full Text Available Background. Carbohydrate 19.9 antigen (CA19.9 has been used in the diagnosis and followup of gastrointestinal tumours. The aim of this prospective longitudinal study was the evaluation of CA19.9 levels in patients with chronic hepatitis and hepatic cirrhosis hepatitis C virus and B virus correlated. Materials and Methods. 180 patients were enrolled, 116 with HCV-related chronic liver disease (48% chronic hepatitis, 52% cirrhosis and 64 with HBV-related chronic liver disease (86% chronic hepatitis, 14% cirrhosis. Patients with high levels of CA19.9 underwent abdominal ecography, gastroendoscopy, colonoscopy, and abdominal CT scan. Results. 51.7% of patients with HCV-related chronic liver disease and 48.4% of those with HBV-related chronic liver disease presented high levels of CA19.9. None was affected by pancreatic or intestinal neoplasia, cholestatic jaundice, or other diseases potentially able to induce Ca19.9 elevations. CA19.9 levels were elevated in 43.3% of HCV chronic hepatitis, in 56.3% of HCV cirrhosis, in 45.1% of HBV chronic hepatitis, and in 58% of HBV cirrhosis. Conclusions. CA19.9 commonly increases in the serum of patients with chronic viral hepatitis. Elevation of CA 19.9 is not specific for neoplastic disease and is related to the severity of fibrosis and to the viral aetiology of hepatitis.

    The glyco-isoforms of intact apolipoprotein C3 (ApoC3) were used to probe glycomic changes associated with obesity and recovery following bariatric surgery, liver diseases such as chronic hepatitis C (CHC) and alcoholic liver cirrhosis, as well as severe, multiorgan diseases such as sepsis and graft vs host disease (GVHD). ApoC3 glyco-isoform ratios responded to unique stimuli that did not correlate with serum lipids or with other blood components measured in either a control population or a group of extremely obese individuals. However, glyco-isoform ratios correlated with obesity with a 1.8-fold change among subjects eligible for bariatric surgery relative to a nonobese control population. Bariatric surgery resulted in rapid change of isoform distribution to that of nonobese individuals, after which the distribution was stable in each individual. Although multiple simultaneous factors complicated effector attribution, the isoform ratios of very obese individuals were nearly normal for diabetic individuals on metformin therapy. Glyco-isoform ratios were sensitive to liver diseases such as chronic hepatitis C and alcoholic liver cirrhosis. The correlation coefficient with fibrosis was superior to that of current assays of serum enzyme levels. Diseases of pregnancy that can result in liver damage, HELLP syndrome and pre-eclampsia, did not alter ApoC3 glyco-isoform ratios. Early after umbilical cord blood transplantation the isoform ratios changed and returned to normal in long-term survivors. Larger changes were observed in persons who died. GVHD had little effect. Persons with severe sepsis showed altered ratios. Similar cut-points for mortality (3.5-fold difference from controls) were found for UCBT and sepsis. Similar values characterized liver cirrhosis. Overall, while changes of glyco-isoform ratios occurred in many situations, individual stability of isoform distribution was evident and large changes were limited to high-level disease.

    Purpose To further observe and verify the effect of nonalcoholic fatty liver disease (NAFLD) on the response to antiviral therapy in patients with chronic hepatitis B (CHB) and investigate the relationship between the virologic response and insulin resistance. Patients and methods A retrospective study was adopted and 61 NAFLD patients with HBeAg-positive CHB were included as the observation group (group A), and 64 patients with simple CHB were included as the control group (group B). Results After 12 weeks of treatment with entecavir, the total virologic response rate in group A was statistically significantly lower than that in group B (P0.05). In weeks 48 and 96, there was no significant difference in the HBeAg seroconversion rates between the two groups (P>0.05). In weeks 12 and 24, there was also no significant difference in the alanine transaminase (ALT) normalization rate between the two groups (P>0.05). Then, in weeks 48 and 96, the ALT normalization rate of group A was obviously lower than that of group B (PM) according to the median value (M=2.79) of the baseline homeostatic model assessment method insulin resistance levels. In weeks 48 and 96, the ALT normalization rate of group A1 was significantly higher than that of group A2 (P<0.05). The correlation coefficient (r) of the baseline homeostatic model assessment method insulin resistance level and the severity of fatty liver in group A was 0.426 (P=0.001). Conclusion NAFLD cannot affect the long-term total virologic response rate and HBeAg seroconversion rate in CHB patients treated with entecavir but can reduce the long-term biochemical response rate, which has a positive correlation with the severity of fatty liver and the insulin resistance index.

    Fluroquinolone antibiotics have been reported to have antiviral properties against RNA viruses, including hepatitis C virus (HCV). In the present study, five patients with advanced liver disease secondary to chronic HCV received 500 mg daily of oral ciprofloxacin for 30 days. Serum HCV-RNA levels and liver enzyme abnormalities remained largely unchanged. Thus, the role of fluoroquinolones as antiviral agents for chronic HCV in patients with advanced liver disease appears to be limited.

    Full Text Available Abstract Background 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. Methods 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. Results 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.

    AIM: To investigate the association between nonalcoholic fatty liver disease (NAFLD) and liver cancer, and NAFLD prevalence in different liver tumors. METHODS: This is a retrospective study of the clinical, laboratory and histological data of 120 patients diagnosed with primary or secondary hepatic neoplasms and treated at a tertiary center where they underwent hepatic resection and/or liver transplantation, with subsequent evaluation of the explant or liver biopsy. The following criteria were used to exclude patients from the study: a history of alcohol abuse, hepatitis B or C infection, no tumor detected in the liver tissue examined by histological analysis, and the presence of chronic autoimmune hepatitis, hemochromatosis, Wilson’s disease, or hepatoblastoma. The occurrence of NAFLD and the association with its known risk factors were studied. The risk factors considered were diabetes mellitus, impaired glucose tolerance, impaired fasting glucose, body mass index, dyslipidemia, and arterial hypertension. Presence of reticulin fibers in the hepatic neoplasms was assessed by histological analysis using slide-mounted specimens stained with either hematoxylin and eosin or Masson’s trichrome and silver impregnation. Analysis of tumor-free liver parenchyma was carried out to determine the association between NAFLD and its histological grade. RESULTS: No difference was found in the association of NAFLD with the general population (34.2% and 30.0% respectively, 95%CI: 25.8-43.4). Evaluation by cancer type showed that NAFLD was more prevalent in patients with liver metastasis of colorectal cancer than in patients with hepatocellular carcinoma and intrahepatic cholangiocarcinoma (OR = 3.99, 95%CI: 1.78-8.94, P < 0.001 vs OR = 0.60, 95%CI: 0.18-2.01, P = 0.406 and OR = 0.70, 95%CI: 0.18-2.80, P = 0.613, respectively). There was a higher prevalence of liver fibrosis in patients with hepatocellular carcinoma (OR = 3.50, 95%CI: 1.06-11.57, P = 0.032). Evaluation of the

  18. Proteasome inhibitor treatment in alcoholic liver disease

    2011-01-01

    Oxidative stress, generated by chronic ethanol consumption, is a major cause of hepatotoxicity and liver injury. Increased production of oxygen-derived free radicals due to ethanol metabolism by CYP2E1 is principally located in the cytoplasm and in the mitochondria, which does not only injure liver cells, but also other vital organs, such as the heart and the brain. Therefore, there is a need for better treatment to enhance the antioxidant response elements. To date, there is no established treatment to attenuate high levels of oxidative stress in the liver of alcoholic patients. To block this oxidative stress, proteasome inhibitor treatment has been found to significantly enhance the antioxidant response elements of hepatocytes exposed to ethanol. Recent studies have shown in an experimental model of alcoholic liver disease that proteasome inhibitor treatment at low dose has cytoprotective effects against ethanol-induced oxidative stress and liver steatosis. The beneficial effects of proteasome inhibitor treatment against oxidative stress occurred because antioxidant response elements (glutathione peroxidase 2, superoxide dismutase 2, glutathione synthetase, glutathione reductase, and GCLC) were upregulated when rats fed alcohol were treated with a low dose of PS-341 (Bortezomib, Velcade(r)). This is an important finding because proteasome inhibitor treatment up-regulated reactive oxygen species removal and glutathione recycling enzymes, while ethanol feeding alone down-regulated these antioxidant elements. For the first time, it was shown that proteasome inhibition by a highly specific and reversible inhibitor is different from the chronic ethanol feeding-induced proteasome inhibition. As previously shown by our group, chronic ethanol feeding causes a complex dysfunction in the ubiquitin proteasome pathway, which affects the proteasome system, as well as the ubiquitination system.

Methods Thirty cases of healthy control group, and 60 case group with chronic liver disease,including both 30 chronic hepatitis B and 30 cirrhosis. liver function in case group was analysed by venous blood samples. Case groups were divided into three groups according to MELD score: <30 group in 27 cases, 30 to 36 group in 17 cases, >36 group in 16 cases. All cases underwent liver magnetic resonance DWI. Among the case group, 15 cases were followed-up twice of pre- and aftertreatment. DWI images were read, ADC values of liver parenchyma were measured and standardized with the cephalospinal fluid (CSF) at the same slice. Used SPSS 13.0 for windows to treat the data, group comparison of ADC values were treated by one-factor analysis of variance, interclass comparison each other by SNK method, comparison between pretherapy and post-treatment by paired-samples t test. Results Healthy liver parenchyma of the control group is homogeneous signal on DWI. ADC pseudo-color pictures showed green on the homogeneous areas. Slightly restricted area of chronic hepatitis B showed irregular scattered patchy in DWI images, 25 cases in right and left lobes, 5 cases only in right lobe of the liver. ADC pseudo-color pictures reaveled blue region in proliferation-constrained areas. Restricted areas of the liver parenchymal become more evident, also showed an irregular liver edge in 30 cases of cirrhosis. The standarized ADC average values were: the healthy group (0. 47 ±0. 02) × 10-3 mm2/s, chronic hepatitis B group (0. 37 ±0. 03) × 10-3 mm2/s, cirrhosis group (0. 36 ±0. 04) × 10-3 mm2/s( F =97.05,P <0. 05).The difference between healthy group and patients group was statistically significant (P < 0. 05 ).

    This study was conducted to measure the concentrations of strontium (Sr), barium (Ba), cadmium (Cd), copper (Cu), zinc (Zn), manganese (Mn), chromium (Cr), antimony (Sb), selenium (Se), and lead (Pb) in canine liver, renal cortex, and renal medulla, and the association of these concentrations with age, gender, and occurrence of chronic kidney disease (CKD). Tissues from 50 dogs were analyzed using inductively coupled plasma mass spectrometry. Cu, Zn, and Mn levels were highest in the liver followed by the renal cortex and renal medulla. The highest Sr, Cd, and Se concentrations were measured in the renal cortex while lower levels were found in the renal medulla and liver. Female dogs had higher tissue concentrations of Sr (liver and renal medulla), Cd (liver), Zn (liver and renal cortex), Cr (liver, renal cortex, and renal medulla), and Pb (liver) than male animals. Except for Mn and Sb, age-dependent variations were observed for all element concentrations in the canine tissues. Hepatic Cd and Cr concentrations were higher in dogs with CKD. In conclusion, the present results provide new knowledge about the storage of specific elements in canine liver and kidneys, and can be considered important reference data for diagnostic methods and further investigations.

    AIH is characterized by chronic inflammation of the liver, interface hepatitis, hypergammaglobulinemia, and production of autoantibodies. Based on the nature of the serum autoantibodies, two types of AIH are recognized: type 1 (AIH-1), positive for ANA and/or anti-smooth muscle antibody, and type 2 (AIH-2), defined by the positivity for anti-liver kidney microsomal type 1 antibody or for anti-liver cytosol type 1 antibody. AIH demonstrates a female preponderance with the female-to-male ratio of 4:1 in AIH-1 and 10:1 in AIH-2. Several genes confer susceptibility to AIH and influence clinical manifestation, response to treatment, and overall prognosis. Most are located within the human leukocyte antigen (HLA) region, which is involved in the presentation of antigenic peptides to T cells and thus in the initiation of adaptive immune responses. The strongest associations are found within the HLA-DRB1 locus. In patients with increased genetic susceptibility to AIH, immune responses to liver autoantigens could be triggered by molecular mimicry. Because of molecular mimicry, different environmental agents, drugs, and viruses might produce AIH. In AIH, T cells are numerically and functionally impaired, permitting the perpetuation of effector immune responses with ensuing persistent liver destruction. AIH is rare but highly treatable inflammatory condition of the liver. Subclinical and asymptomatic disease is common. AIH therefore needs to be considered in the differential diagnosis of all patients with elevated liver enzymes. Clinical response to immunosuppressive therapy is characteristic and supports the diagnosis.

    Over the last four decades, chronic ethanol feeding studies in rodents using either ad libitum feeding or intragastric infusion models have significantly enhanced our understanding of the pathogenesis of alcoholic liver disease (ALD). Recently, we developed a chronic plus binge alcohol feeding model in mice that is similar to the drinking patterns of many alcoholic hepatitis patients: a history of chronic drinking and recent excessive alcohol consumption. Chronic+binge ethanol feeding synergistically induced steatosis, liver injury, and neutrophil infiltration in mice, which may be useful for the study of early alcoholic liver injury and inflammation. Using this chronic+binge model, researchers have begun to identify novel mechanisms that participate in the pathogenesis of alcoholic liver injury, thereby revealing novel therapeutic targets. In this review article, we briefly discuss several mouse models of ALD with a focus on the chronic+binge ethanol feeding model.

    Full Text Available Chronic liver disease is a considerable burden on society, being one of the three main causes of death in certain regions of Africa and Asia. Liver transplant is the only treatment option for cirrhosis, which is the end stage of many chronic liver diseases. This article reviews the preventable causes of cirrhosis and the preventive strategies which could be implemented in order to avoid the catastrophic consequences of cirrhosis. With small variations around the world, 70 to 80% of the end stage liver diseases are caused by excessive alcohol consumption and by viral hepatitis, both of which are potentially preventable. Excessive alcohol consumption has important public health consequences because of its involvement not only with cirrhosis, but also with motor vehicle accidents, unemployment, domestic violence etc. Among the viral causes, Hepatitis Virus B and C have the greatest impact on public health. Effective vaccine is available for Hepatitis Virus B and must be put in use. While a vaccine for Hepatitis Virus C is awaited, effective preventive strategies should be undertaken to avoid the preventable cases of end stage liver disease.As doenças hepáticas crônicas estão entre as três principais causas de morte na África e Ásia.O transplante de fígado é o único tratamento curativo para esta doença hepática de caráter terminal.O presente artigo tem como objetivo apresentar as causas passíveis de prevenção de cirrose e as estratégias que podem ser utilizadas no sentido de preveni-las. Com pequenas variações ao redor do mundo, 70 a 80 % das doenças hepáticas terminais são causadas por consumo excessivo de álcool e por hepatites virais que são doenças passíveis de prevenção.O consumo excessivo de álcool é importante problema de saúde pública, pois envolve violência doméstica, acidentes de trânsito, além da possível evolução para cirrose e suas conseqüências. Entre as causas virais as hepatites pelo vírus B

    evaluate in our healthcare area the clinical, ultrasonographic, and evolutionary features of patients with chronic liver disease and angioma-like liver lesions on ultrasonography. Materials and methods: we conducted a retrospective study amongst patients seen at the Ultrasonography Unit, Gastroenterology Department between January 2000 and June 2004. Included in the study were patients that presented with clinical and/or laboratory complaints consistent with chronic liver disease of any etiology, and those in which abdominal ultrasounds revealed the existence of at least one angioma-like liver lesion. All relevant epidemiological, clinical, ultrasonographic, and evolutionary data were carefully collected and recorded. Results: in the course of our study, 58 patients were diagnosed with chronic liver disease and angioma-like liver lesions, of which 13 showed clinical, laboratory, ultrasonographic, and/or histological signs of liver cirrhosis. In 50% of patients these lesions were less than 10 mm in diameter, and in most cases were located in the right hepatic lobe. During an average follow-up period of 35 months (6-168 months we verified that, in two patients, these lesions, initially interpreted as angiomas were in fact malignancies (one hepatocellular carcinoma and one metastatic adenocarcinoma of the gallbladder. In both cases, the patients were cirrhotic. Thus, our study revealed that 15% of lesions found in cirrhotic patients initially interpreted as angiomas were actually malignant. Conclusions: our study revealed that, in patients with chronic liver disease, particularly in cirrhotic patients, a considerable percentage of ultrasonographic lesions originally interpreted as angiomas are in fact malignant tumors.

    Full Text Available The global prevalence of physiologically defined chronic obstructive pulmonary disease (COPD in adults aged >40 yr is approximately 9-10 per cent. Recently, the Indian Study on Epidemiology of Asthma, Respiratory Symptoms and Chronic Bronchitis in Adults had shown that the overall prevalence of chronic bronchitis in adults >35 yr is 3.49 per cent. The development of COPD is multifactorial and the risk factors of COPD include genetic and environmental factors. Pathological changes in COPD are observed in central airways, small airways and alveolar space. The proposed pathogenesis of COPD includes proteinase-antiproteinase hypothesis, immunological mechanisms, oxidant-antioxidant balance, systemic inflammation, apoptosis and ineffective repair. Airflow limitation in COPD is defined as a postbronchodilator FEV1 (forced expiratory volume in 1 sec to FVC (forced vital capacity ratio <0.70. COPD is characterized by an accelerated decline in FEV1. Co morbidities associated with COPD are cardiovascular disorders (coronary artery disease and chronic heart failure, hypertension, metabolic diseases (diabetes mellitus, metabolic syndrome and obesity, bone disease (osteoporosis and osteopenia, stroke, lung cancer, cachexia, skeletal muscle weakness, anaemia, depression and cognitive decline. The assessment of COPD is required to determine the severity of the disease, its impact on the health status and the risk of future events (e.g., exacerbations, hospital admissions or death and this is essential to guide therapy. COPD is treated with inhaled bronchodilators, inhaled corticosteroids, oral theophylline and oral phosphodiesterase-4 inhibitor. Non pharmacological treatment of COPD includes smoking cessation, pulmonary rehabilitation and nutritional support. Lung volume reduction surgery and lung transplantation are advised in selected severe patients. Global strategy for the diagnosis, management and prevention of Chronic Obstructive Pulmonary Disease

    Abstract Real-life data on interferon (IFN)-free direct acting antiviral (DAA) therapies for chronic hepatitis C (CHC) is limited for Asian Americans. To evaluate sustained virologic response (SVR) and adverse events (AE) in Asian Americans treated with sofosbuvir (SOF)-based, IFN-free DAA therapies. This is a retrospective study of 110 consecutive Asian Americans with HCV genotypes 1 to 3 or 6 treated with IFN-free SOF-based regimens for 8 to 24 weeks between February 2014 and March 2016 at a university center in Northern California. Mean age was 63 ± 12 years, mean BMI was 25 ± 6 (kg/m2), and about half (52%) were male. Most patients were infected with HCV genotype 1 (HCV-1, 64%), followed by HCV-2 (14%), HCV-6 (13%), and HCV-3 (8%). Half had cirrhosis, and the majority of these (67%) had decompensation. Overall SVR12 was 93% (102/110), and highest among patients without cirrhosis, liver transplant, or HCC (100%, 37/37). SVR12 was lower among patients with HCC (82%, 14/17), decompensated cirrhosis (84%, 31/37), or liver transplant (89%, 17/19), regardless of treatment and genotype. Most common AEs were anemia (25%), fatigue (20%), and headache (12%). Anemia was highest in patients receiving SOF/RBV (67%). There was 1 treatment-unrelated serious adverse effect (SAE). There were 7 dose reductions due to anemia or fatigue from RBV and 2 treatment discontinuations due to fatigue or loss of insurance authorization. This real-life cohort of Asian American CHC patients treated with IFN-free SOF-based therapies showed high overall treatment response and good tolerability, despite very high rates of advanced disease and prior treatment failure.

    AIM: To identify the frequency of iron overload and study the three mutations in the HFE gene (C282Y,H63D, and S65C) in patients with chronic liver disorders (CLD) and controls.METHODS: To identify patients with iron overload (transferrin saturation > 45% in females and > 50% in males and serum ferritin > 1000 ng/mL) we evaluated 236 patients with CLD, including 59 with non-alcoholic steatohepatitis (NASH), 22 with alcoholic liver disease (ALD), 19 of cirrhosis due to viruses (HBV, HCV), and 136 with cryptogenic cirrhosis. Mutations of the HFE gene were analyzed by PCR-RE. hundred controls were screened for iron status and the mutations.RESULTS: Seventeen patients with CLD showed evidence of iron overload. Fifteen cases of iron overload had cryptogenic cirrhosis and two had ALD. None of the controls showed iron overload. We did not find any individual with 282Y or 65C either in the cases or in the controls. The prevalence of H63D heterozygosity was 12% in normal individuals, 14.8% in 236 patients (16.9% in NASH, 13.6% in ALD, 26.3% in viral and 12.5% in cryptogenic cirrhosis) and the overall prevalence was 13.98%. Only two of the 17 patients with primary iron overload were heterozygous for H63D. One patient with NASH and one normal individual who were homozygous for H63D showed no iron overload.CONCLUJSION: Primary iron overload in Indians is nonHFE type, which is different from that in Europeans and further molecular studies are required to determine the defect in various iron regulatory genes.

  12. HEMOSTATIC DISORDERS IN LIVER DISEASES

    Directory of Open Access Journals (Sweden)

    A. F. Minov

    2010-01-01

    Full Text Available The liver is an essential player in the pathway of coagulation in both primary and secondary hemostasis as it is the site of synthesis of all coagulation factors and their inhibitors. Liver diseases are associated with complex changes in coagulation and the delicate balance between pro and antithrombotic factors is preserved but reset to a lower level. There is growing evidence that portal and hepatic vein thrombosis is cause of disease progression in cirrhotic patients and worsens hemostatic abnormalities. These hemostatic abnormalities do not always lead to spontaneous bleeding, which may be triggered only by additional factors, such as infections. Usually therapy for coagulation disorders in liver disease is needed only during bleeding or before invasive procedures. In patients with end stage liver disease liver transplantation is the only treatment available, which can restore normal hemostasis, and correct genetic clotting defects. During liver transplantation hemorrhage may occur due to the pre-existing hypocoagulable state, the collateral circulation caused by portal hypertension and increased fibrinolysis.

    2008-01-01

    Liver disorders with a likely autoimmune pathogenesis in childhood include autoimmune hepatitis (AIH), autoimmune sclerosing cholangitis (ASC),and de novo AIH after liver transplantation.AIH is divided into two subtypes according to seropositivity for smooth muscle and/or antinuclear antibody (SMA/ANA,type 1) or liver kidney microsomal antibody (LKM1,type 2).There is a female predominance in both.LKM1 positive patients tend to present more acutely,at a younger age,and commonly have partial IgA deficiency,while duration of symptoms before diagnosis,clinical signs,family history of autoimmunity, presence of associated autoimmune disorders,response to treatment,and long-term prognosis are similar in both groups. The most common type of paediatric sclerosing cholangitis is ASC.The clinical,biochemical, immunological,and histological presentation of ASC is often indistinguishable from that of AIH type 1.In both,there are high IgG,non-organ specific autoantibodies,and interface hepatitis.Diagnosis is made by cholangiography.Children with ASC respond to immunosuppression satisfactorily and similarly to AIH in respect to remission and relapse rates,times to normalization of biochemical parameters, and decreased inflammatory activity on follow up liver biopsies. However,the cholangiopathy can progress.There may be evolution from AIH to ASC over the years,despite treatment.De novo AIH after liver transplantation affects patients not transplanted for autoimmune disorders and is strikingly reminiscent of classical AIH,including elevated titres of serum antibodies, hypergammaglobulinaemia,and histological findings of interface hepatitis,bridging fibrosis,and collapse.Like classical AIH,it responds to treatment with prednisolone and azathioprine.De novo AIH post liver transplantation may derive from interference by calcineurin inhibitors with the intrathymic physiological mechanisms of T-cell maturation and selection.Whether this condition is a distinct entity or a form of

    The liver is an essential player in the pathway of coagulation in both primary and secondary haemostasis.Only von Willebrand factor is not synthetised by the liver, thus liver failure is associated with impairment of coagulation. However, recently it has been shown that the delicate balance between pro and antithrombotic factors synthetised by the liver might be reset to a lower level in patients with chronic liver disease. Therefore,these patients might not be really anticoagulated in stable condition and bleeding may be caused only when additional factors, such as infections, supervene. Portal hypertension plays an important role in coagulopathy in liver disease, reducing the number of circulating platelets, but platelet function and secretion of thrombopoietin have been also shown to be impaired in patients with liver disease. Vitamin K deficiency may coexist, so that abnormal clotting factors are produced due to lack of gamma carboxylation. Moreover during liver failure, there is a reduced capacity to clear activated haemostatic proteins and protein inhibitor complexes from the circulation. Usually therapy for coagulation disorders in liver disease is needed only during bleeding or before invasive procedures. When end stage liver disease occurs, liver transplantation is the only treatment available, which can restore normal haemostasis, and correct genetic clotting defects, such as haemophilia or factor V Leiden mutation. During liver transplantation haemorrage may occur due to the pre-existing hypocoagulable state, the collateral circulation caused by portal hypertension and increased fibrinolysis which occurs during this surgery.

    Patients with chronic liver diseases sustain impairment to immune systems, which worsens over time. These defects in their host defense lead to risks of bacterial infections and increased morbidity. Providers should have heightened surveillance for infectious diseases and suspect one with any acute change in status. Patient history may reveal rare infections and allow initiation of early appropriate therapy. There should be a low threshold for obtaining diagnostic cultures and peritoneal fluid samples and discussing possible causes with an infectious diseases consultant or a microbiology laboratory. These maneuvers will maximize therapy in patients at high risk for death due to infectious disease.

    2009-12-01

    Anemia of chronic disease is normocytic and normochromic. One of the mechanisms is misbalance of iron metabolism. Hepcidin, a kind of protein secreted by liver is considered to be the hormone regulating iron metabolism. It binds to ferroportin and induces the latter one's internalization. Thus, iron transportation from iron storage cells to serum is reduced. Cytokines are elevated in chronic disease. They stimulate hepcidin expression in liver through JAK2/STAT3 pathway. As a result, iron absorption and reabsorption is blocked, which leads to the misbalance of iron metabolism in anemia of chronic disease. In this article, the hepcidin and its relation to iron metabolism and anemia in chronic disease are reviewed.

    Alcoholic liver disease (ALD) is the second most common diagnosis among patients undergoing liver transplantation (LT) in Europe and in the United States. The outcome of patients transplanted for ALD is at least as good as that for most other diagnoses and better than that for hepatitis C virus. In case of severe acute alcoholic hepatitis (AAH) non-responders to medical therapy, the reason for denying LT is that it requires abstinence from alcohol for six months before consideration for a transplant. A strict application of a period of abstinence as a policy for transplant eligibility is unfair to non-responder patients, as most of them will have died prior to the end of the six-month sober period. In our opinion, in severe AAH subjects with a good social support, with the frequency of self-help groups (alcoholics anonymous or association of clubs of alcoholics in treatment), with the frequency of Alcohol Unit and without severe psychotic or personality disorders, the lack of pre-LT abstinence alone should not be a barrier against being listed.

    Highlights: • The use of MR to classify cirrhosis in different stages is a new interesting field. • We compared liver and spleen T1 mapping, T2 mapping and diffusion-weighted imaging. • MR relaxometry using liver T1 mapping is accurate for the diagnosis of cirrhosis. • Liver T1 mapping shows that values increase with the severity of cirrhosis. • Diffusion-weighted imaging is less accurate than T1 mapping while T2 mapping is not reliable. - Abstract: Background: MR relaxometry has been extensively studied in the field of cardiac diseases, but its contribution to liver imaging is unclear. We aimed to compare liver and spleen T1 mapping, T2 mapping, and diffusion-weighted MR imaging (DWI) for assessing the diagnosis and severity of cirrhosis. Methods: We prospectively included 129 patients with normal (n = 40) and cirrhotic livers (n = 89) from May to September 2014. Non-enhanced liver T1 mapping, splenic T2 mapping, and liver and splenic DWI were measured and compared for assessing cirrhosis severity using Child-Pugh score, MELD score, and presence or not of large esophageal varices (EVs) and liver stiffness measurements using Fibroscan{sup ®} as reference. Results: Liver T1 mapping was the only variable demonstrating significant differences between normal patients (500 ± 79 ms), Child-Pugh A patients (574 ± 84 ms) and Child-Pugh B/C patients (690 ± 147 ms; all p-values <0.00001). Liver T1 mapping had a significant correlation with Child-Pugh score (Pearson's correlation coefficient of 0.46), MEDL score (0.30), and liver stiffness measurement (0.52). Areas under the receiver operating characteristic curves of liver T1 mapping for the diagnosis of cirrhosis (O.85; 95% confidence intervals (CI), 0.77–0.91), Child-Pugh B/C cirrhosis (0.87; 95%CI, 0.76–0.93), and large EVs (0.75; 95%CI, 0.63–0.83) were greater than that of spleen T2 mapping, liver and spleen DWI (all p-values < 0.01). Conclusion: Liver T1 mapping is a promising new diagnostic

    Full Text Available Liver fibrosis and cirrhosis are a major cause of morbidity and mortality worldwide. Development of the fibrotic scar is an outcome of chronic liver diseases of varying aetiologies including alcoholic liver disease (ALD nonalcoholic liver disease (NAFLD including non-alcoholic steatohepatitis (NASH viral hepatitis B and C (HBV, HCV. The critical step in the development of scar is activation of hepatic stellate cells (HSCs, which become the primary source of extracellular matrix. Aberrant apoptosis is a feature of chronic liver diseases and is associated with worsening stages of fibrosis. However, apoptosis is also the main mechanism promoting the resolution of fibrosis, and spontaneous or targeted apoptosis of HSC is associated with regression of fibrosis in animal models and patients with chronic liver disease. Given the importance of apoptosis in disease progression and resolution, there is much interest in precisely delineating the mechanisms involved and also developing biomarkers that accurately reflect the underlying pathogenesis. Here, we review the mechanisms driving apoptosis in development of liver disease and use of apoptosis -related biomarkers to aid in clinical diagnosis. Finally, we will also examine the recent literature regarding new insights into mechanisms involved in apoptosis of activated HSCs as possible method of fibrosis regression.

    2014-04-01

    Coffee is one of the most commonly consumed beverages in the world. Its health benefits including improved overall survival have been demonstrated in a variety of disease states. To examine the association of coffee consumption with liver disease, a systematic review of studies on the effects of coffee on liver associated laboratory tests, viral hepatitis, nonalcoholic fatty liver disease (NAFLD), cirrhosis and hepatocellular carcinoma (HCC) was performed. Coffee consumption was associated with improved serum gamma glutamyltransferase, aspartate aminotransferase and alanine aminotransferase values in a dose dependent manner in individuals at risk for liver disease. In chronic liver disease patients who consume coffee, a decreased risk of progression to cirrhosis, a lowered mortality rate in cirrhosis patients, and a lowered rate of HCC development were observed. In chronic hepatitis C patients, coffee was associated with improved virologic responses to antiviral therapy. Moreover, coffee consumption was inversely related to the severity of steatohepatitis in patients with non-alcoholic fatty liver disease. Therefore, in patients with chronic liver disease, daily coffee consumption should be encouraged.

    Full Text Available The liver alongside the heart and the brain is the largest and the most vital organ within the human body whose absence leads to certain death. In addition, diagnosis of liver diseases takes a long time and requires sufficient expertise of physicians. To this end, statistical methods as automatic prediction systems can help specialists to diagnose liver diseases quickly and accurately. The Discrete Hidden Markov Model (DHMM is an intelligent and a strong statistical model used to predict the types of liver diseases in patients in this study. The data in this crosssectional study included information elicited from the records of 1143 patients with 5 different types of liver diseases including cirrhosis of the liver, liver cancer, acute hepatitis, chronic hepatitis, and fatty liver disease admitted to Afzalipour Hospital in the city of Kerman in the time period of 2006-2013. At first, the type of diseases for each patient was identified; however, it was assumed that the type of diseases is unknown and there were attempts to diagnose the type of the disease through the DHMM to examine its accuracy. Therefore, the DHMM was fitted to the data and its performance was evaluated by using the parameters of accuracy, sensitivity, and specificity. Such parameters of the model were separately calculated for the diagnosis of liver diseases. The highest levels of accuracy, sensitivity, and specificity were associated with the diagnosis of cirrhosis of the liver and equal to 0.77, 0.82, 0.96, respectively; and the lowest levels were related to the diagnosis of fatty liver disease with an accuracy level of 0.65 and a sensitivity level of 0.69. As well, the specificity level in the diagnosis of fatty liver disease was 0.94. The results of this study indicated the potential ability of the DHMM; thus, the use of this model in terms of diagnosing liver diseases was strongly recommended.

    Aims. To develop a noninvasive score model to predict NASH in patients with combined CHB and NAFLD. Objective and Methods. 65 CHB patients with NAFLD were divided into NASH group (34 patients) and non-NASH group (31 patients) according to the NAS score. Biochemical indexes, liver stiffness, and Controlled Attenuation Parameter (CAP) were determined. Data in the two groups were compared and subjected to multivariate analysis, to establish a score model for the prediction of NASH. Results. In the NASH group, ALT, TG, fasting blood glucose (FBG), M30 CK-18, CAP, and HBeAg positive ratio were significantly higher than in the non-NASH group (P analysis showed that CK-18 M30, CAP, FBG, and HBVDNA level were independent predictors of NASH. Therefore, a new model combining CK18 M30, CAP, FBG, and HBVDNA level was established using logistic regression. The AUROC curve predicting NASH was 0.961 (95% CI: 0.920–1.00, cutoff value is 0.218), with a sensitivity of 100% and specificity of 80.6%. Conclusion. A noninvasive score model might be considered for the prediction of NASH in patients with CHB combined with NAFLD.

    2011-06-01

    Primary biliary cirrhosis (PBC) and primary sclerosing cholangitis (PSC) represent major indications for liver transplantation (LT). Despite the steady increase in the incidence and prevalence of PBC, the number of liver transplants for PBC has fallen in recent years, whereas the number of transplants for PSC has remained stable. Indications for LT for PBC and PSC are no different from those of other causes of chronic liver disease, apart from some disease-specific indications. PBC and PSC have more favourable outcomes after LT, compared to viral hepatitis and alcohol-associated liver disease. Numerous studies have clearly demonstrated that PBC and PSC recur after LT. The diagnosis of recurrent disease should be made on agreed criteria. The impact of recurrent disease on survival is unclear. Study of recurrent PBC and PSC may provide a better understanding of the mechanisms of these diseases in the native liver.

    Science.gov (United States)

    Alonso, José Castellote

    2010-12-01

    Hepatic hydrothorax is the paradigmatic pleural effusion in liver cirrhosis. It is defined as a pleural effusion in a patient with portal hypertension and no cardiopulmonary disease. The estimated prevalence of this complication in patients with liver cirrhosis is 5 to 6%. Its pathophysiology involves movement of ascitic fluid from the peritoneal cavity into the pleural space through diaphragmatic defects. Thoracentesis and pleural fluid analysis are necessary for diagnosis. Initial management consists of sodium restriction, diuretics, and therapeutic thoracentesis. A transjugular intrahepatic portosystemic shunt may provide a bridge prior to liver transplantation. Spontaneous bacterial empyema is the infection of a preexisting hydrothorax. The more frequent bacteria involved are ENTEROBACTERIACEAE and gram-positive cocci. Antibiotic therapy is the cornerstone of therapy. This article reviews etiology, clinical manifestations, and therapy of these two complications of liver cirrhosis and portal hypertension.

    AIM: To determine the efficacy of long-term lamivudine treatment of a large number of Japanese patients with chronic hepatitis B.METHODS: In this retrospective, multi-center trial,318 Japanese patients with chronic hepatitis B received 100 mg of lamivudine daily for up to 36 (median 21) mo. Virological response was a decline to a serum HBV DNA level less than 3.7 log copies/mL. Virological breakthrough was defined as the reappearance of a serum HBV DNA level to more than 10-fold the minimum during treatment.RESULTS: Lamivudine produced virological response in 86.8% of the 318 patients at 6 mo, in 80.2% of 252 patients at 12 mo, in 69.2% of 133 patients at 24 mo, and in 53.6% of 28 patients at 36 mo. Forward stepwise logistic regression analysis showed an HBV DNA level less than 6.8 log copies/mL (P< 0.0001), HBeAg negativity (P< 0.0001), a platelet count of 100× 109/L or more (P= 0.0162) at baseline, and a decline of the HBV DNA level of more than 3.2 log copies/mL as compared with the baseline level at 3 mo after the start of treatment (P= 0.0003) to be significantly associated with virological response. Among patients with a virological response, virological breakthrough was seen in 5.3% of 19 patients who responded virologically at 1 mo, in 20.7% of 203 patients at 3 mo, in 27.5% of 51 patients at 6 mo, in 33.3% of 12 patients at 9 mo, and in 100% of 3 patients at ≥ 15 mo. A virological breakthrough was found significantly more often in patients with delayed virological response.CONCLUSION: Lamivudine treatment could suppress serum HBV DNA in most of the tested Japanese patients.Long-term efficacy might be seen in patients without HBeAg at baseline, in the absence of cirrhosis, and in patients with a decline in HBV DNA level soon after the start of treatment.

    Wilson disease and cholestatic liver diseases may present as a diagnostic dilemma if standard guidelines incorporating markers of copper overload are followed. We hereby present a series of four cases of sclerosing cholangitis masquerading as Wilson disease. True Wilson disease cases had significantly lower ceruloplasmin (6 vs. 16 mg/dL) and higher 24-hour urinary copper (322.3 vs. 74.5 μg/day) as compared to mimickers. Initial low serum ceruloplasmin levels normalized in mimickers on follow up, and this may used as a diagnostic indicator. Standard Wilson disease diagnostic criteria thus need further modification especially in developing countries to help avoid mismanagement.

  13. Obesity, fatty liver disease and intestinal microbiota.

    Nonalcoholic fatty liver disease (NAFLD) is a chronic liver disorder that is increasing in prevalence with the worldwide epidemic of obesity. NAFLD is the hepatic manifestation of the metabolic syndrome. The term NAFLD describes a spectrum of liver pathology ranges from simple steatosis to steatosis with inflammation nonalcoholic steatohepatitis and even cirrhosis. Metabolic syndrome and NAFLD also predict hepatocellular carcinoma. Many genetic and environmental factors have been suggested to contribute to the development of obesity and NAFLD, but the exact mechanisms are not known. Intestinal ecosystem contains trillions of microorganisms including bacteria, Archaea, yeasts and viruses. Several studies support the relationship between the intestinal microbial changes and obesity and also its complications, including insulin resistance and NAFLD. Given that the gut and liver are connected by the portal venous system, it makes the liver more vulnerable to translocation of bacteria, bacterial products, endotoxins or secreted cytokines. Altered intestinal microbiota (dysbiosis) may stimulate hepatic fat deposition through several mechanisms: regulation of gut permeability, increasing low-grade inflammation, modulation of dietary choline metabolism, regulation of bile acid metabolism and producing endogenous ethanol. Regulation of intestinal microbial ecosystem by diet modifications or by using probiotics and prebiotics as a treatment for obesity and its complications might be the issue of further investigations.

    AIM: To assess the prevalence of the two mutations, C282Y and H63D of HFE gene, in healthy subjects, patients with chronic hepatitis C (CHC), and patients with nonalcoholic fatty liver disease (NAFLD) in Taiwan and to explore the contribution of the HFE mutation on serum iron stores in CHC and NAFLD groups.METHODS: We examined C282Y and H63D mutations of HFE gene in 125 healthy subjects, 29 patients with CHC,and 33 patients with NAFLD. The serum iron markers,including ferritin, iron, and total iron binding capacity (TIBC),were assessed in all patients.RESULTS: All of the healthy subjects and patients were free from C282Y mutation. The prevalence of H63D heterozygosity was 4/125 (3.20%) in healthy subjects, 2/29(6.90%) in CHC group, and 1/33 (3.03%) in NAFLD group.The healthy subjects showed no significant difference in the prevalence of H63D mutation as compared with the CHC or NAFLD group. Increased serum iron store was found in 34.48% of CHC patients and 36.36% of NAFLD patients.In three patients of H63D heterozygosity, only one CHC patient had increased serum iron store. There was no significant difference in the prevalence of HFE mutations between patients with increased serum iron store and those without in CHC or NAFLD group.CONCLUSION: The HFE mutations may not contribute to iron accumulation in the CHC or NAFLD group even when serum iron overload is observed in more than one-third of these patients in Taiwan.

    The role of hepatitis B virus (HBV) genetics in the clinical manifestations of infection is being increasingly recognized. Genotype D is one of eight currently recognized major HBV genotypes. The virus is ubiquitous worldwide, but shows different features in different regions. One hundred and ninety-eight patients with chronic HBV infection were enrolled in this study, 38 of whom had been diagnosed with cirrhosis of the liver and/or hepatocellular carcinoma. HBV DNA was isolated from the patients' blood samples and the entire genome and/or the basal core promoter/core promoter region sequenced. Phylogenetic analysis of the complete genomes revealed that subgenotype D1 is the most prevalent subgenotype in Turkey, but there was no definite phylogenetic grouping according to geography for isolates from different regions within Turkey, or for isolates in Turkey relative to other parts of the world. Turkish isolates tended to be genetically similar to European and central Asian isolates. Overall, HBV-infection in Turkey appears to be characterized by early HBeAg seroconversion, a high incidence of the A1896 core promoter mutation and a small viral load. Genotype D characteristic mutations A1757 and T1764/G1766 were found in the BCP region. T1773 was associated with T1764/G1766 and a larger viral load. In conclusion, infection with HBV genotype D in Turkey has a similar clinical outcome to that of Europe and central Asia. Genotypic mutations in genotype D may be linked with disease prognosis in Turkey, but further studies with higher sample numbers and balanced clinical groups are needed to confirm this.

    Full Text Available Background. Hepatitis C virus (HCV infection can exert proatherogenic activities due to its direct action on vessel walls and/or via the chronic inflammatory process involving the liver. Aims. To clarify the role of HCV in atherosclerosis development in monoinfected HCV patients at different degrees of liver fibrosis and with no risk factors for coronary artery disease. Methods. Forty-five patients were included. Clinical, serological, and anthropometric parameters, liver fibrosis (transient liver elastometry (fibroscan and aspartate aminotransferase to platelet ratio index (APRI, carotid intima-media thickness (c-IMT, and brachial artery flow-mediated vasodilatation (FMD were assessed. Patients were divided into 3 tertiles according to fibroscan values. Results. Patients in the third tertile (fibroscan value >11.5 KPa showed FMD values were significantly lower than second and first tertiles (4.7±1.7% versus 7.1±2.8%, p=0.03. FMD values were inversely related to liver elastomeric values. c-IMT values were normal. The risk for endothelial dysfunction development in the third tertile (p=0.02 was 6.9 higher than the first tertile. A fibroscan value >11.5 KPa had a positive predictive power equal to 79% for endothelial dysfunction. Conclusions. HCV advanced liver fibrosis promotes atherosclerosis by inducing endothelial dysfunction independently of common cardiovascular risk factors.

    Liver transplantation remains an effective treatment for those with end-stage disease and with intractable liver-related symptoms.The shortage of organs for transplantation has resulted in the need for rationing.A variety of approaches to selection and allocation have been developed and vary from country to country.The shortage of donors has meant that new approaches have to be adopted to make maximal use of the available organs;these include splitting grafts,use of extended criteria livers,livers from nonheart-beating donors and from living donors.Post transplantation, most patients will need life-long immunosuppression,although a small proportion can have immunosuppression successfully withdrawn.Newer immunosuppressive drugs and different strategies may allow a more targeted approach with a reduction in sideeffects and so improve the patient and graft survival.For autoimmune diseases, transplantation is associated with significant improvement in the quality and length of life.Disease may recur after transplantation and may affect patient and graft survival.

    Full Text Available Hepcidin, a liver hormone, is important for both innate immunity and iron metabolism regulation. As dysfunction of the hepcidin pathway may contribute to liver pathology, we analysed liver hepcidin mRNA and serum hepcidin in patients with chronic liver diseases. Hepcidin mRNA levels were determined in liver biopsies obtained from 126 patients with HCV (n = 21, HBV (n = 23, autoimmune cholestatic disease (primary biliary cirrhosis and primary sclerosing cholangitis; PBC/PSC; n = 34, autoimmune hepatitis (AIH; n = 16 and non-alcoholic fatty liver disease (NAFLD; n = 32. Sera sampled on the biopsy day from the same patients were investigated for serum hepcidin levels. Hepatic hepcidin mRNA levels correlated positively with ferritin and negatively with serum γ-GT levels. However, no correlation was found between serum hepcidin and either ferritin or liver hepcidin mRNA. Both serum hepcidin and the serum hepcidin/ferritin ratio were significantly lower in AIH and PBC/PSC patients' sera compared to HBV, HCV or NAFLD (P<0.001 for each comparison and correlated negatively with serum ALP levels. PBC/PSC and AIH patients maintained low serum hepcidin during the course of their two-year long treatment. In summary, parallel determination of liver hepcidin mRNA and serum hepcidin in patients with chronic liver diseases shows that circulating hepcidin and its respective ratio to ferritin are significantly diminished in patients with autoimmune liver diseases. These novel findings, once confirmed by follow-up studies involving bigger size and better-matched disease subgroups, should be taken into consideration during diagnosis and treatment of autoimmune liver diseases.

    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 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

    Chronic kidney disease (CKD) is a frequent complication of HIV infection, occurring in 3.5 - 48.5%, and occurs as a complication of HIV infection, other co-morbid disease and infections and as a consequence of therapy of HIV infection and its complications. The classic involvement of the kidney by HIV infection is HIV-associated nephropathy (HIVAN), occurring typically in young adults of African ancestry with advanced HIV disease in association with APOL1 high-risk variants. HIV-immune complex disease is the second most common diagnosis obtained from biopsies of patients with HIV-CKD. CKD is mediated by factors related to the virus, host genetic predisposition and environmental factors. The host response to HIV infection may influence disease phenotype through activation of cytokine pathways. With the introduction of antiretroviral therapy (ART), there has been a decline in the incidence of HIVAN, with an increasing prevalence of focal segmental glomerulosclerosis. Several studies have demonstrated the overall improvement in kidney function when initiating ART for HIV CKD. Progression to end stage kidney disease has been reported to be more likely when high grade proteinuria, severely reduced eGFR, hepatitis B and/C co-infection, diabetes mellitus, extensive glomerulosclerosis, and chronic interstitial fibrosis are present. Improved renal survival is associated with use of renin angiotensin system blockers and viral suppression. Many antiretroviral medications are partially or completely eliminated by the kidney and require dose adjustment in CKD. Certain drug classes, such as the protease inhibitors and the non-nucleoside reverse transcriptase inhibitors, are metabolized by the liver and do not require dose adjustment. HIV-infected patients requiring either hemo- or peritoneal dialysis, who are stable on ART, are achieving survival rates comparable to those of dialysis patients without HIV infection. Kidney transplantation has been performed successfully in HIV

  6. Is liver biopsy mandatory in children with chronic hepatitis C?

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Liver biopsy is considered the most accurate means to estimate the necroinflammatory activity and the extent of fibrosis. However, histology evaluation is an invasive procedure associated with risk to the patient, risk of sampling error and diagnostic inconsistencies due to inter- and intra-observer error. On the basis of histological studies performed so far, chronic hepatitis C in children appears morphologically benign in the majority of cases.At the Pediatric Liver Unit of our university, a total of 67 children with chronic hep, atitis C underwent liver biopsy.Liver biopsy was repeated 5.5 years after the initial histological evaluation in 21 children. On a total number of 88 liver biopsies, micronodular cirrhosis was detected only in one genotype 1b-infected obese child. Since liver histology investigation of a child with chronic hepatitis C has few chances to highlight severe lesions, we question how liver biopsy helps in the management of children with chronic hepatitis C.

    Objective To develop the Chinese (Mainland) version of Chronic Liver Disease Questionnaire (CLDQ) and use it to assess the health-related quality of life (HRQoL) of chronic hepatitis B (CHB) patients in China and identify the determinants of HRQoL. Methods The Chinese (Mainland) CLDQ was developed by expert consultation, focus group interviews with patients, and pilot study. The final version of questionnaire was adopted to assess the HRQoL of chronic hepatitis B outpatients enrolled from two largest infectious hospitals in Beijing. Cronbach’ s alpha was used to measure the internal consistency reliability. The construct validity was measured by factor analysis. T-test, one-way analysis of variance (ANOVA), and multi-variable linear regression were used to analyze the data. Results Cronbach’s alpha of the overall CLDQ is 0.935, ranging from 0.628 to o.881 among six subscales. Six factors were identified via factor analysis, including a new factor sleeping(SL). A total of 519 patients with CHB were included in the investigation with the final version of questionnaire, 405 of them were only with CHB, 53 with compensated cirrhosis, and 61 with decompensated cirrhosis. The CHB group scored the highest in the overall score of CLDQ (p<0.05). The score of worry (WO) domain was significantly lower in the compensated group than the CHB group (p<0.05). Decompensated cirrhosis patients scored lower than the CHB group in all CLDQ domains and the overall score (p<0.05). Stages of illness, gender, regular visits to specialized hospitals, and work status in last year were determinants of HRQoL. Conclusion The psychometric properties of the Chinese(Mainland) CLDQ is acceptable. The HRQoL of CHB patients deteriorated with disease progression. Advanced stages of CHB, female, long time absence from work after illness, and no job or retirement were determinants of poor HRQoL. Regular visits to specialized hospitals was a positive determinant of HRQoL. PMID:27631983

    Full Text Available Nonalcoholic fatty liver disease (NAFLD is increasing in pediatric age group parallel to the growing prevalence of obesity and overweight all around the world. So changing in life style and   interventions on obesogenic environment is cornerstone of NAFLD therapy in obese children. Some experts recommend that children and adolescents be encouraged to follow a low-fat, low-glycemic-index diet that includes eating a minimum of 5 servings of vegetables and fruits daily, engaging in physical activity for at least 1 hour daily, and minimizing television/computer time to 2 hours daily.  In spite of effectiveness of weight loss and exercise in improvement NAFLD, this goal is very difficult to be achieved and pharmacological approaches have become necessary. Pharmacologic therapies against one or more specific factors and/or molecules involved in the development of NAFLD (i.e., insulin resistance, free fatty acid lipid toxicity, and oxidative stress also might slow the progression of NAFLD to NASH or cirrhosis.  On this basis, insulin sensitizers, antioxidants, cytoprotective agents, and dietary supplementations have been evaluated in pediatric clinical trials but there is no approved pharmacologic therapy for NAFLD or NASH. Not all obese children affected by NAFLD. Diet modification and regular exercise beside to serial medical follow up highly suggested for this group of children. Normal weight and thin children with NAFLD or NASH should be investigated appropriately in a logical manner based on causes of primary liver steatosis in children and treatment of underlying disease can cause improvement fatty liver in these patients.   Keywords: Non-alcoholic fatty liver disease; Non-alcoholic steatohepatitis; Children; Steatosis; Treatment

    Since their discovery more than a decade ago microRNAs have been demonstrated to have profound effects on almost every aspect of biology. Numerous studies in recent years have shown that microRNAs have important roles in development and in the etiology and progression of disease. This review is focused on microRNAs and the roles they play in liver development, regeneration and liver disease; particularly chronic liver diseases such as alcoholic liver disease, non-alcoholic fatty liver disease, non-alcoholic steatohepatitis, viral hepatitis and primary liver cancer. The key microRNAs identified in liver development and chronic liver disease will be discussed together with, where possible, the target messenger RNAs that these microRNAs regulate to profoundly alter these processes. This article is part of a Directed Issue entitled: The Non-coding RNA Revolution.

    Polycystic liver disease is characterized by the presence of multiple bile duct-derived epithelial cysts scattered in the liver parenchyma. The natural history and clinical manifestations of polycystic liver disease are based on the disease as it manifests in patients with autosomal dominant polycystic kidney disease (ADPKD). The occurrence of polycystic liver disease independently from polycystic kidney disease has been known for a long time. More recently, a gene for autosomal dominant polycystic liver disease has been identified on chromosome 19p 13.2-13.1. Isolated polycystic liver disease is underdiagnosed and genetically distinct from polycystic liver disease associated with ADPKD but with similar pathogenesis and clinical manifestations. We report here two men with polycystic liver disease no associated with ADPKD. Ultrasound and computed tomography imaging were effective in documenting the underlying lesions non-invasively.

Recent epidemiologic studies have connected the anemia of chronic disease with critical illness, obesity, aging, and kidney failure, as well as with the well-established associations of cancer, chronic infection, and autoimmune disease. Functional iron deficiency, mediated principally by the interaction of interleukin-6, the iron regulatory hormone hepcidin, and the iron exporter ferroportin, is a major contributor to the anemia of chronic disease. Although anemia is associated with adverse outcomes, experimental models suggest that iron sequestration is desirable in the setting of severe infection. Experimental therapeutic approaches targeting interleukin-6 or the ferroportin-hepcidin axis have shown efficacy in reversing anemia in either animal models or human patients, although these agents have not yet been approved for the treatment of the anemia of chronic disease.

  14. Alcoholic liver disease and the gut-liver axis

    Alcoholic liver disease (ALD) is one of the leading causes of liver diseases and liver-related death worldwide. Of the many factors that contribute to the pathogenesis of ALD, gut-derived lipopolysaccharide (LPS) plays a central role in induction of steatosis, inflammation, and fi brosis in the liver. In this review, we discuss the mechanisms by which alcohol contributes to increased gut permeability, the activation of Kupffer cells, and the infl ammatory cascade by LPS. The role of the Toll-like receptor 4...

    Cytomegalovirus (CMV) remains one of the most frequent viral infections and the most common cause of death after liver transplantation (LT). Chronic allograft liver rejection remains the major obstacle to long-term allograft survival and CMV infection is one of the suggested risk factors for chronic allograft rejection. The precise relationship between cytomegalovirus and chronic rejection remains uncertain.This review addresses the morbidity of cytomegalovirus infection and the risk factors associated with it, the relationship between cytomegalovirus and chronic allograft liver rejection and the potential mechanisms of it.

    The complement system plays an important role in mediating both acquired and innate responses to defend against microbial infection, and in disposing immunoglobins and apoptotic cells. The liver (mainly hepatocytes) is responsible for biosynthesis of about 80-90% of plasma complement components and expresses a variety of complement receptors.Recent evidence from several studies suggests that the complement system is also involved in the pathogenesis of a variety of liver disorders including liver injury and repair, fibrosis, viral hepatitis, alcoholic liver disease, and liver ischemia/reperfusion injury. In this review, we will discuss the potential role of the complement system in the pathogenesis of liver diseases.

    Full Text Available Disorders of the hepatobiliary system are relatively common extraintestinal manifestations of inflammatory bowel disease (IBD. These disorders are sometimes due to a shared pathogenesis with IBD as seen in primary sclerosing cholangitis (PSC and small-duct primary sclerosing cholangitis (small-duct PSC. There are also hepatobiliary manifestations such as cholelithiasis and portal vein thrombosis that occur due to the effects of chronic inflammation and the severity of bowel disease. Lastly, medications used in IBD such as sulfasalazine, thiopurines, and methotrexate can adversely affect the liver. It is important to be cognizant of these disorders as some do have serious long-term consequences. The management of these disorders often requires the expertise of multidisciplinary teams to achieve the best outcomes.

    Institute of Scientific and Technical Information of China (English)

    2016-01-01

    Alcoholic liver disease (ALD) remains an important healthproblem worldwide. The disease spectrum is featuredby early steatosis, steatohepatitis (steatosis with inflammatorycells infiltration and necrosis), with someindividuals ultimately progressing to fibrosis/cirrhosis.Although the disease progression is well characterized,no effective therapies are currently available for thetreatment in humans. The mechanisms underlying theinitiation and progression of ALD are multifactorial andcomplex. Emerging evidence supports that adiposetissue dysfunction contributes to the pathogenesis ofALD. In the first part of this review, we discuss themechanisms whereby chronic alcohol exposure contributedto adipose tissue dysfunction, including cell death,inflammation and insulin resistance. It has been longknown that aberrant hepatic methionine metabolismis a major metabolic abnormality induced by chronicalcohol exposure and plays an etiological role in thepathogenesis of ALD. The recent studies in our groupdocumented the similar metabolic effect of chronicalcohol drinking on methionine in adipose tissue. Inthe second part of this review, we also briefly discussthe recent research progress in the field with a focuson how abnormal methionine metabolism in adiposetissue contributes to adipose tissue dysfunction and liverdamage.

    Liver transplantation has been remarkably effective in the treatment in patients with end-stage liver disease. However, disparity between solid-organ supply and increased demand is the greatest limitation, resulting in longer waiting times and increase in mortality of transplant recipients. This situation creates the need to seek alternatives to orthotopic liver transplantation.Hepatocyte transplantation or liver cell transplantation has been proposed as the best method to support patients. The procedure consists of transplanting individual cells to a recipient organ in sufficient quantity to survive and restore the function. The capacity of hepatic regeneration is the biological basis of hepatocyte transplantation. This therapeutic option is an experimental procedure in some patients with inborn errors of metabolism, fulminant hepatic failure and acute and chronic liver failure, as a bridge to orthotopic liver transplantation. In the Hospital La Fe of Valencia, we performed the first hepatocyte transplantation in Spain creating a new research work on transplant program.

    Abstract In recent years, increasingly evidences show that autophagy plays an important role in the pathogenesis and development of liver diseases, and the relationship between them has increasingly become a focus of concern. Autophagy refers to the process through which the impaired organelles, misfolded protein, and intruding microorganisms is degraded by lysosomes to maintain stability inside cells. This article states the effect of autophagy on liver diseases (hepatic fibrosis, fatty liver, viral hepatitis, and liver cancer), which aims to provide a new direction for the treatment of liver diseases.

    In a proportion of liver cirrhosis, the etiology continues to remain elusive. It is uncertain whether and to what extent cirrhosis evolving from nonalcoholic fatty liver disease contributes to this group of cryptogenic cirrhosis because the clinicopathologic features of nonalcoholic fatty liver disease cirrhosis are largely unknown. We explored these facets by examining the explant livers and clinical data in living donor liver transplant recipients. Among 103 adult liver transplant recipients with different types of chronic liver disease, 30 had a pre-liver transplant diagnosis of cryptogenic cirrhosis. A final categorization of the native liver disease was attempted in these cases on the basis of detail pathomorphological findings in adequately sampled explant liver correlated with careful review of pre-liver transplant clinical data. Of the 30 cryptogenic cirrhosis cases, 19 (63.3%) finally labeled as nonalcoholic fatty liver disease cirrhosis showed histologic features in several respects different from those reported for the early and established phases of nonalcoholic fatty liver disease. Steatosis was infrequent and focal or even absent, whereas variable grades of Mallory hyaline and inflammation were consistently present. Ductular proliferation and hydropic change of hepatocytes were also frequent. Only 9 (47%) of the 19 cases had nonalcoholic fatty liver disease associated risk factors like diabetes and obesity. It was concluded that appreciation of quantitative and qualitative differences in hepatic morphology between the cirrhotic and the early/established stage of nonalcoholic fatty liver disease will help in making a correct diagnosis of nonalcoholic fatty liver disease cirrhosis in the proper clinical setting. When appropriate criteria are used, nonalcoholic fatty liver disease appears to account for close to two thirds of cases currently labeled as cryptogenic cirrhosis.

    Liver biopsy is a standard method used for obtaining liver tissue for histopathological evaluation. Since reliable serological and virological tests are currently available, liver biopsy is no longer needed for the etiological diagnosis of chronic hepatitis B and C. However, liver histology remains the gold standard as a prognostic tool, providing information about the liver disease progression (grading of necroinflammatory activity and staging of fibrosis) and serving clinicians in the management and therapeutic decisions. In general, histopathological evaluation is indicated before starting the antiviral treatment. Main limitations of the liver biopsy include its invasive and painful procedure, sampling errors and the inter- and intra-observer variability. In addition, indications for the liver biopsy in pediatric patients with chronic viral hepatitis were questioned recently, and efforts have been made toward the development of non-invasive methods as an alternative to the liver biopsy. The most commonly used methods are novel imaging studies (elastography) and combinations of biomarkers. However, to date, none of these tests was validated in children with chronic viral hepatitis. In this review, we present the current status of the liver biopsy in the management of chronic viral hepatitis B and C in pediatric population, including specific indications, complications, contraindications, problems, limitations, and alternative non-invasive methods.

    Full Text Available Non-alcoholic fatty liver disease (NAFLD is the most prevalent form of chronic liver disease in the world, paralleling the epidemic of obesity and Type 2 diabetes mellitus (T2DM. NAFLD exhibits a histological spectrum, ranging from “bland steatosis” to the more aggressive necro-inflammatory form, non-alcoholic steatohepatitis (NASH which may accumulate fibrosis to result in cirrhosis. Emerging data suggests fibrosis, rather than NASH per se, to be the most important histological predictor of liver and non-liver related death. Nevertheless, only a small proportion of individuals develop cirrhosis, however the large proportion of the population affected by NAFLD has led to predictions that NAFLD will become a leading cause of end stage liver disease, hepatocellular carcinoma (HCC, and indication for liver transplantation. HCC may arise in non-cirrhotic liver in the setting of NAFLD and is associated with the presence of the metabolic syndrome (MetS and male gender. The MetS and its components also play a key role in the histological progression of NAFLD, however other genetic and environmental factors may also influence the natural history. The importance of NAFLD in terms of overall survival extends beyond the liver where cardiovascular disease and malignancy represents additional important causes of death.

    Full Text Available BACKGROUND: 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. METHODOLOGY: 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. PRINCIPAL FINDINGS: 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. CONCLUSIONS: sTNFR:IgG-Fc improved survival rate during development of ACLF via ameliorating liver injury with a potential therapeutic value.

    Fatty liver is the most common liver disease worldwide.Patients with fatty liver disease die primarily from cardiovascular disease and not from chronic liver diseases. Hyperglycemia and hyperinsulinemia induce lipogenesis, thereby increasing the hepatic pool of fatty acids. This pool is also increased by increased delivery of fatty acids through the diet or lipolysis in adipose tissue. Nutritional consultations and lifestyle modification are important in the treatment of non-alcoholic fatty liver disease (NAFLD). Among the dietary constituents, combination of vitamin D, vitamin E, and omega-3 fatty acids shows promise for the treatment of NAFLD.

In 11 patients (28.2% there was agreement between the diagnoses established before and after biopsy, however, in 14 patients (35.9%, there was disagreement. The yield of diagnosis was low when patients were suspected for cirrhosis. The procedure was well tolerated by the majority of patients. Nonetheless, 1 presented intra-abdominal bleeding and required immediate surgery to control retroperitoneal hemorrhage. CONCLUSIONS: Transjugular liver biopsy is useful for the histopathologic diagnosis of patients with chronic liver diseases whenever the percutaneous route is contraindicated. In this series we obtained histopathologic diagnosis for 64,1% of the subjects studied. Patients suspected of having cirrhosis had a low yield of histopathologic diagnosis (50% when compared to subjects without clinical evidence for crrhosis (78,9%. The technique is rather complex, and can cause serious complications. This, it should be performed in reference centers in radiology and hepatology.

    Full Text Available Obesity with associated comorbidities is currently a worldwide epidemic and among the most challenging health conditions in the 21st century. A major metabolic consequence of obesity is insulin resistance which underlies the pathogenesis of the metabolic syndrome. Nonalcoholic fatty liver disease (NAFLD is the hepatic manifestation of obesity and metabolic syndrome. It comprises a disease spectrum ranging from simple steatosis (fatty liver, through nonalcoholic steatohepatitis (NASH to fibrosis, and ultimately liver cirrhosis. Abnormality in lipid and lipoprotein metabolism accompanied by chronic inflammation is the central pathway for the development of metabolic syndrome-related diseases, such as atherosclerosis, cardiovascular disease (CVD, and NAFLD. This paper focuses on pathogenic aspect of lipid and lipoprotein metabolism in NAFLD and the relevant mouse models of this complex multifactorial disease.

    2009-01-01

    Alcoholic liver disease (ALD) and hepatitis C virus (HCV) infection represent, either alone or in combination, more than two thirds of all patients with liver disease in the Western world. This review discusses the epidemiology and combined impact of ALD and HCV on the progression of liver disease. ALD and HCV affect the progression of liver disease to liver cirrhosis and hepatocellular carcinoma (HCC) in a synergistic manner. Thus, the risk for HCC increases five times with a daily alcohol consumption of 80 g; in the presence of HCV it is increased 20-fold, and a combination of both risk factors leads to a more than 100-fold risk for HCC development. Alcohol consumption also decreases the response to interferon treatment which is probably due to a lack of compliance than a direct effect on HCV replication. Several molecular mechanisms are discussed that could explain the synergistic interaction of alcohol and HCV on disease progression. They include modulation of the immune response and apoptosis, increased oxidative stress via induction of CYP2E1 and the hepatic accumulation of iron. Thus, both HCV and alcohol independently cause hepatic iron accumulation in > 50% of patients probably due to suppression of the liver-secreted systemic iron hormone hepcidin. A better understanding of hepcidin regulation could help in developing novel therapeutic approaches to treat the chronic disease in the future. For now, it can be generally concluded that HCV-infected patients should abstain from alcohol and alcoholics should be encouraged to participate in detoxification programs.

    Women more commonly present with acute liver failure, autoimmune hepatitis, benign liver lesions, primary biliary cirrhosis, and toxin-mediated hepatotoxicity. Women less commonly have malignant liver tumors, primary sclerosing cholangitis, and viral hepatitis. There is a decreased rate of decompensated cirrhosis in women with hepatitis C virus infection, no survival difference in alcohol-related liver disease, and improved survival from hepatocellular carcinoma. In general, men are 2-fold more likely to die from chronic liver disease and cirrhosis than are women. Liver transplant occurs less commonly in women than in men, with variable disease outcomes based on etiology. This review highlights the epidemiology, natural history, treatment outcomes, and pathophysiology of common liver diseases in women and discusses how gender influences disease incidence, presentation, progression, and outcomes. Pregnancy-related liver disease is not covered.

  9. Spontaneous rupture of the liver in a patient with chronic hepatitis B and D

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Spontaneous rupture of the liver is a rare condition with serious consequences, if not recognized and treated in time. It has been reported as a complication of several disorders, including benign or malignant liver tumors,connective tissue disease, infiltrating liver disease,preeclampsia, and post anticoagulant therapy. We report a case of spontaneous rupture of liver in a noncirrhotic, chronic hepatitis B and D patient presenting with acute hemoperitoneum and shock. The subcapsular hematoma and rupture of liver were documented by image studies. The patients' condition gradually stabilized after fluid resuscitation. The reported case and literature review suggest that spontaneous rupture of liver must be considered in a differential diagnosis of acute hemoperitoneum. A high index of suspicion and early diagnosis with imaging are critically important.

    Full Text Available Introduction: Chronic pancreatitis and liver disease are two conditions that commonly co-exist in chronic alcoholics with variable incidences. Aim: To evaluate frequency pancreatitis in patients with a history of chronic alcohol abuse. Materials and Methods: A total of 390 autopsies over 11 year′s period were included in the study. Gross and microscopic assessment of liver and pancreas were performed. Available clinical and laboratory parameters were recorded. Results: Age ranged from 22 to 65 years with a mean age of 45.32 years. All 390 consecutive patients included in the study were males. Majority of the patients had primarily presented with alcohol related liver diseases whereas few had presented with features of pancreatitis. Micronodular cirrhosis was present in 292 cases. Features of chronic pancreatitis were observed in 42 cases and 8 of these cases had associated changes of acute hemorrhagic pancreatitis. Prevalence of pancreatitis was more in cirrhotics as compared to non-cirrhotics, and acute pancreatitis was mostly seen in non-cirrhotics. Dominant pattern of fibrosis was perilobular followed by periductal, intralobular and diffuse. Conclusion: Chronic pancreatitis as evidence by the presence of parenchymal fibrosis was more frequently observed in alcoholic cirrhosis cases than that in non-cirrhotic alcoholic liver disease, thereby suggesting common underlying pathobiology in the development of fibrosis in liver as well as in pancreas.

    Constant alcohol consumption is a major cause of chronic liver disease, and there has been a growing concern regarding the increased mortality rates worldwide. Alcoholic liver diseases (ALDs) range from mild to more severe conditions, such as steatosis, steatohepatitis, fibrosis, cirrhosis, and hepatocellular carcinoma. The liver is enriched with innate immune cells (e.g. natural killer cells and Kupffer cells) and hepatic stellate cells (HSCs), and interestingly, emerging evidence suggests that innate immunity contributes to the development of ALDs (e.g. steatohepatitis and liver fibrosis). Indeed, HSCs play a crucial role in alcoholic steatosis via production of endocannabinoid and retinol metabolites. This review describes the roles of the innate immunity and HSCs in the pathogenesis of ALDs, and suggests therapeutic targets and strategies to assist in the reduction of ALD.

    2016-05-01

    Recent progress has allowed a more comprehensive study of the gut microbiota. Gut microbiota helps in health maintenance and gut dysbiosis associates with chronic metabolic diseases. Modulation of short-chain fatty acids and choline bioavailability, lipoprotein lipase induction, alteration of bile acid profile, endogenous alcohol production, or liver inflammation secondary to endotoxemia result from gut dysbiosis. Modulation of the gut microbiota by pre/probiotics gives promising results in animal, but needs to be evaluated in human before use in clinical practice. Gut microbiota adds complexity to the pathophysiology of nonalcoholic fatty liver disease but represents an opportunity to discover new therapeutic targets.

    Psoriasis is a chronic inflammatory immune-mediated skin disease, frequently associated with systemic comorbidities. According to recent data, patients with psoriasis show a greater prevalence of metabolic syndrome, which confers a higher cardiovascular risk. The link between these pathological conditions appears to be a chronic low-grade inflammatory status. The aim of this review is to focus on the multiple epidemiological and physio-pathogenetic aspects linking non-alcoholic fatty liver disease, psoriasis, and cardiovascular disease.

    2016-03-01

    After transplantation of nonrenal solid organs, an acute decline in kidney function develops in the majority of patients. In addition, a significant number of nonrenal solid organ transplant recipients develop chronic kidney disease, and some develop end-stage renal disease, requiring renal replacement therapy. The incidence varies depending on the transplanted organ. Acute kidney injury after nonrenal solid organ transplantation is associated with prolonged length of stay, cost, increased risk of death, de novo chronic kidney disease, and end-stage renal disease. This overview focuses on the risk factors for posttransplant acute kidney injury after liver and heart transplantation, integrating discussion of proteinuria and chronic kidney disease with emphasis on pathogenesis, histopathology, and management including the use of mechanistic target of rapamycin inhibition and costimulatory blockade.

    Non-alcoholic fatty liver disease (NAFLD) is a broad term that includes liver diseases characterized by abnormal hepatocellular accumulations of lipid that cannot be related to alcohol abuse. It may be found in both adults and children, particularly those who are obese or have insulin resistance. Steatohepatitis is a specific pattern of injury within the spectrum of NAFLD and this pattern is associated with fibrotic progression and cirrhosis. In addition to steatohepatitis, a distinct form of fibrotic fatty liver disease exists in children. There have been a number of recent advances in the characterization of histologic changes in NAFLD. In light of these recent reports, this study will: (1) review the histologic features of steatosis and nonalcoholic steatohepatitis in adults; (2) review the variation of histologic patterns of pediatric fatty liver disease; and (3) discuss the validity and use of the nonalcoholic fatty liver disease Activity Score.

    End-stage liver disease,due to cholestatic liver diseases with an autoimmune background such as primary biliary cirrhosis(PBC)and primary sclerosing cholangitis(PSC),is considered a good indication for liver transplantation.Excellent overall patient and graft outcomes,based mostly on the experience from deceased donor liver ransplantation(DDLT),have been reported.Due to the limited number of oraan donations from deceased donors in most Asian countries,living donor liver transplantation(LDLT)is the mainstream treatment for end-stage liver disease,including that resulting from PBC and PSC.Although the initial experiences with LDLT for PBC and PSC seem satisfactory or comparable to that with DLT,some aspects,including the timing of transplantation,the risk of recurrent disease,and its long-term clinical implications,require further evaluation.Whether or not the long-term outcomes of LDLT from a biologically related donor are equivalent to that of DDLT requires further observations.The clinical course following LDLT may be affected by he genetic background shared between the recipient and the living related donor.(C)2008 The WJG Press.All rights reserved.

    The seroepidemiology of Leptospira infection in patients suffering from liver disease has been poorly studied. Information about risk factors associated with infection in liver disease patients may help in the optimal planning of preventive measures. We sought to determine the association of Leptospira IgG seroprevalence and patients with liver diseases, and to determine the characteristics of the patients with Leptospira exposure. We performed a case-control study of 75 patients suffering from liver diseases and 150 age- and gender-matched control subjects. Diagnoses of liver disease included liver cirrhosis, steatosis, chronic hepatitis, acute hepatitis, and amoebic liver abscess. Sera of participants were analyzed for the presence of anti- Leptospira IgG antibodies using a commercially available enzyme immunoassay. Anti-Leptospira IgG antibodies were found in 17 (22.7%) of 75 patients and in 15 (10.0%) of 150 control subjects (OR = 2.32; 95% CI: 1.09-4.94; P=0.03). This is the first age- and gender-matched case control study about Leptospira seroprevalence in patients with liver diseases. Results indicate that Leptospira infection is associated with chronic and acute liver diseases. Results warrants for additional studies on the role of Leptospira exposure in chronic liver disease.

    Hepatic involvement in Wilson disease (WD) manifests as a diffuse chronic disease in the majority of patients. However, in a subset of patients focal liver lesions may develop, presenting with a wide range of imaging features. The majority of focal liver lesions in patients with WD are benign nodules, but there are reports that have described malignant liver tumors or dysplastic nodules in these patients. Because of the possibility of malignant transformation of liver nodules, major concerns have been raised with respect to the management and follow-up of patients with WD in whom focal liver lesions have been identified. The assessment of liver involvement in patients with WD is generally performed with ultrasonography. However, ultrasonography conveys limited specificity so that magnetic resonance (MR) imaging is often performed to improve lesion characterization. This review was performed to illustrate the spectrum of MR imaging features of focal liver lesions that develop in patients with WD. It is assumed that familiarity with the MR imaging presentation of focal liver lesions in WD may help clarify the actual nature of hepatic nodules in patients with this condition.

    Branched-chain amino acids (BCAAs) are a group of essential amino acids including valine, leucine and isoleucine. A low ratio of plasma BCAAs to aromatic amino acids is a physiological hallmark of liver cirrhosis. Recent studies on BCAAs have revealed that, in addition to their role as protein constituents, they may have a role as pharmacological nutrients for patients with chronic liver disease. This review summarizes the possible effects of BCAAs on albumin synthesis and insulin resistance from clinical and basic viewpoints. Meanwhile, the newly discovered clinical impact of BCAAs on the prognosis and quality of life of patients with hepatocellular carcinoma and liver cirrhosis are reviewed.%支链氨基酸是一组包括缬氨酸、亮氨酸和异亮氨酸等的人体必需氨基酸.支链氨基酸除了其蛋白质成分的作用,可能对慢性肝病患者具有药理营养素作用.本文从基础研究和临床角度对支链氨基酸在合成白蛋白和胰岛素抵抗作用上可能产生的影响,以及对肝癌和肝硬化患者的生活质量和预后的临床作用作一综述.

    Metformin, a biguanide derivative, is the most commonlyprescribed medication in the treatment of type 2 diabetesmellitus. More recently, the use of metformin has shownpotential as a preventive and therapeutic agent for abroad spectrum of conditions, including liver diseaseand hepatic malignancies. In this systematic review,we critically analyze the literature behind the potentialuse of metformin across the spectrum of liver diseaseand malignancies. The PubMed and Ovid MEDLINEdatabases were searched from 2000 to March 2015,using a combination of relevant text words and MeSHterms: metformin and mammalian target of rapamycin,hepatitis B virus (HBV), hepatitis B virus (HCV), nonalcoholicfatty liver disease (NAFLD), hepatocellularcarcinoma (HCC) or cholangiocarcinoma. The searchresults were evaluated for pertinence to the issue ofmetformin in liver disease as well as for quality of studydesign. Metformin has a number of biochemical effectsthat would suggest a benefit in treating chronic liverdiseases, particularly in the context of insulin resistanceand inflammation. However, the literature thus far doesnot support any independent therapeutic role in NAFLDor HCV. Nonetheless, there is Level Ⅲ evidence fora chemopreventive role in patients with diabetes andchronic liver disease, with decreased incidence of HCCand cholangiocarcinoma. The use of metformin seemsto be safe in patients with cirrhosis, and provides asurvival benefit. Once hepatic malignancies are alreadyestablished, metformin does not offer any therapeuticpotential. In conclusion, there is insufficient evidence torecommend use of metformin in the adjunctive treatmentof chronic liver diseases, including NAFLD and HCV.However, there is good evidence for a chemopreventiverole against HCC among patients with diabetes andchronic liver disease, and metformin should be continuedin patients even with cirrhosis to provide this benefit.

    2015-01-01

    Liver transplantation (LT) is the most effective treatmentmodality for end stage liver disease caused by manyetiologies including autoimmune processes. That said,the need for transplantation for autoimmune hepatitis(AIH) and primary biliary cirrhosis (PBC), but not forprimary sclerosing cholangitis (PSC), has decreasedover the years due to the availability of effective medicaltreatment. Autoimmune liver diseases have superiortransplant outcomes than those of other etiologies. WhileAIH and PBC can recur after LT, recurrence is of limitedclinical significance in most, but not all cases. RecurrentPSC, however, often progresses over years to a stagerequiring re-transplantation. The exact incidence andthe predisposing factors of disease recurrence remaindebated. Better understanding of the pathogenesis andthe risk factors of recurrent autoimmune liver diseasesis required to develop preventive measures. In thisreview, we discuss the current knowledge of incidence,diagnosis, risk factors, clinical course, and treatmentof recurrent autoimmune liver disease (AIH, PBC, PSC)following LT.

    Full Text Available The prevalence of hepatitis G virus (HGV in liver disease of non-A, -B, -C viral hepatitis, hepatitis B and hepatitis C was determined. Two of 44 patients (4.5% with liver injury without any hepatitis A, B or C marker were positive for HGV. One of five cases of hepatocellular carcinoma was positive for HGV. One of three cases with fulminant hepatitis was positive for HGV. This case was negative at the onset of fulminant hepatitis and became positive after plasmapheresis. No patient with acute (n=8 or chronic (n=5 hepatitis or liver cirrhosis (n=8 was positive for HGV in non-A, -B, -C liver disease. One of 30 patients with various HBV-positive liver diseases and nine (17.3 of 52 patients with type C liver disease were positive for HGV. In patients with hepatitis C, four (28.6% of 14 HGV-co-infected patients were complicated with diabetes mellitus compared with four (10.5% of 38 single hepatitis C virus (HCV-infected patients (not significant. In 12 HGV-positive patients, eight of 10 (80% had a history of blood transfusion. In HCV-positive patients, co-infection with HGV was not a risk factor in patients with diabetes mellitus as a complication. HGV appeared to cause non-A, -B, -C hepatitis rarely, and its main route of infection was blood transfusion.

    2011-01-01

    microRNAs (miRs) are small non-coding RNAs that regulate both mRNA and protein expression of target genes, which results in alterations in mRNA stability or translation inhibition. miRs influence at least one third of all human transcripts and are known regulators of various important cellular growth and differentiation factors. miRs have recently emerged as key regulatory molecules in chronic liver disease. This review details recent contributions to the field of miRs that influence liver development and the broad spectrum of disease, from non-alcoholic fatty liver disease to fibrosis/cirrhosis, with particular emphasis on hepatic stellate cells and potential use of miRs as therapeutic tools.

    In addition to its effects in the liver, chronic hepatitis C virus (HCV) infection can have serious consequences for other organ systems. Extrahepatic manifestations include mixed cryoglobulinemia (MC) vasculitis, lymphoproliferative disorders, renal disease, insulin resistance, type 2 diabetes, sicca syndrome, rheumatoid arthritis-like polyarthritis, and autoantibody production; reductions in quality of life involve fatigue, depression, and cognitive impairment. MC vasculitis, certain types of lymphoma, insulin resistance, and cognitive function appear to respond to anti-HCV therapy. However, treatments for HCV and other biopsychosocial factors can reduce quality of life and complicate management. HCV treatment has a high overall cost that increases when extrahepatic manifestations are considered. HCV appears to have a role in the pathogenesis of MC vasculitis, certain types of lymphoma, and insulin resistance. Clinicians who treat patients with HCV infections should be aware of potential extrahepatic manifestations and how these can impact and alter management of their patients.

    To evaluate the frequency of single-nucleotide polymorphism at the -88 myxovirus resistance (MxA) gene promoter region in relation to the status of hepatitis C virus (HCV) progression and response to combined interferon (IFN) in chronic HCV Egyptian patients. One hundred ten subjects were enrolled in the study; 60 HCV genotype 4-infected patients who underwent combined IFN therapy and 50 healthy individuals. All subjects were genotyped for -88 MxA polymorphism by the restriction fragment length polymorphism technique. There was an increasing trend of response to combined IFN treatment as 34.9% of GG, 64.3% of GT, and 66.7% of TT genotypes were sustained responders (P=0.05). The T allele was significantly affecting the response rate more than G allele (P=0.032). Moreover, the hepatic fibrosis score and hepatitis activity were higher in GG genotypes compared with the GT and TT genotypes. The multivariate analysis showed that the MxA GG genotype was an independent factor increasing the no response to IFN therapy (P=0.04, odds ratio [OR] 3.822, 95% confidence interval [CI] 1.056-11.092), also MxA G allele (P=0.0372, OR 2.905, 95% CI 1.066-7.919). MxA -88 polymorphism might be a potential biomarker to predict response to IFN and disease progression in chronic HCV-infected patients.

  11. GFR Estimating Equations and Liver Disease.

    Beben, Tomasz; Rifkin, Dena E

    2015-09-01

    It is important to accurately assess the glomerular filtration rate (GFR) of patients with liver disease to deliver care and allocate organs for transplantation in a way that improves outcomes. The most commonly used methods to estimate GFR in this population are based on creatinine, which is biased by these patients' low creatinine production and potentially by elevated serum bilirubin and decreased albumin levels. None of the creatinine-based estimated glomerular filtration rate (eGFR) equations have been specifically modified for a population with liver disease, and even measurement of a 24-hour creatinine clearance has limitations. In liver disease, all creatinine-based estimates of GFR overestimate gold standard-measured GFR, and the degree of overestimation is highest at lower measured GFR values and in more severe liver disease. Cystatin C-based eGFR has shown promise in general population studies by demonstrating less bias than creatinine-based eGFR and improved association with clinically important outcomes, but results in the liver disease population have been mixed, and further studies are necessary. Ultimately, specific eGFR equations for liver disease or novel methods for estimating GFR may be necessary. However, for now, the limitations of currently available methods need to be appreciated to understand kidney function in liver disease.

    Gevers, Tom J G; Drenth, Joost P H

    2013-02-01

    Polycystic liver disease (PLD) is arbitrarily defined as a liver that contains >20 cysts. The condition is associated with two genetically distinct diseases: as a primary phenotype in isolated polycystic liver disease (PCLD) and as an extrarenal manifestation in autosomal dominant polycystic kidney disease (ADPKD). Processes involved in hepatic cystogenesis include ductal plate malformation with concomitant abnormal fluid secretion, altered cell-matrix interaction and cholangiocyte hyperproliferation. PLD is usually a benign disease, but can cause debilitating abdominal symptoms in some patients. The main risk factors for growth of liver cysts are female sex, exogenous oestrogen use and multiple pregnancies. Ultrasonography is very useful for achieving a correct diagnosis of a polycystic liver and to differentiate between ADPKD and PCLD. Current radiological and surgical therapies for symptomatic patients include aspiration-sclerotherapy, fenestration, segmental hepatic resection and liver transplantation. Medical therapies that interact with regulatory mechanisms controlling expansion and growth of liver cysts are under investigation. Somatostatin analogues are promising; several clinical trials have shown that these drugs can reduce the volume of polycystic livers. The purpose of this Review is to provide an update on the diagnosis and management of PLD with a focus on literature published in the past 4 years.

    The prevalence of type 2 diabetes mellitus (T2DM) is higher in patients who have liver diseases such as nonalcoholic fatty liver disease, chronic viral hepatitis, hemochromatosis, alcoholic liver disease and cirrhosis. It is suggested that there is a pathogenic link between the presence of T2DM and the severity of liver injury. However, evidence related to the impact of hepatic inflammation on the development of T2DM has not yet emerged. This article provides an overview of the evidence for an increased prevalence of diabetes in a range of liver diseases, the impact of liver diseases on insulin resistance and β cell dysfunction, and the potential mechanisms whereby coexistent liver diseases exacerbate the development of T2DM.

    The purpose of this review was to examine the impact of varying degrees of renal insufficiency on pregnancy outcome in women with chronic renal disease. Our search of the literature did not reveal any randomized clinical trials or meta-analyses. The available information is derived from opinion, reviews, retrospective series, and limited observational series. It appears that chronic renal disease in pregnancy is uncommon, occurring in 0.03-0.12% of all pregnancies from two U.S. population-based and registry studies. Maternal complications associated with chronic renal disease include preeclampsia, worsening renal function, preterm delivery, anemia, chronic hypertension, and cesarean delivery. The live birth rate in women with chronic renal disease ranges between 64% and 98% depending on the severity of renal insufficiency and presence of hypertension. Significant proteinuria may be an indicator of underlying renal insufficiency. Management of pregnant women with underlying renal disease should ideally entail a multidisciplinary approach at a tertiary center and include a maternal-fetal medicine specialist and a nephrologist. Such women should receive counseling regarding the pregnancy outcomes in association with maternal chronic renal disease and the effect of pregnancy on renal function, especially within the ensuing 5 years postpartum. These women will require frequent visits and monitoring of renal function during pregnancy. Women whose renal disease is further complicated by hypertension should be counseled regarding the increased risk of adverse outcome and need for blood pressure control. Some antihypertensives, especially angiotensin-converting enzyme inhibitors and angiotensin-receptor blockers, should be avoided during pregnancy, if possible, because of the potential for both teratogenic (hypocalvaria) and fetal effects (renal failure, oliguria, and demise).

    The treatment of acute and chronic liver failure is still a challenge despite modern therapeutic innovations. While liver transplantation can restore liver function and improve patient survival, donor shortages limit this treatment to a small number of patients. Cellular xenotransplantation has emerged as an alternative for treating liver failure. Xenohepatocytes could be readily available in sufficient quantities to treat patients in critical condition and thereby reduce the donor shortage. The use of isolated encapsulated or non-encapsulated cells can reduce the immunorejection response. Several studies using animal models of acute or chronic liver failure have demonstrated improved survival and recovery of liver function after xenotransplantation of adult hepatocytes. Porcine liver cells are a potential source of xenohepatocytes due to similarities with human physiology and the great number of hepatocytes that can be obtained. The recent development of less immunogenic transgenic pigs, new immunosuppressive drugs, and cellular encapsulation systems represents important advances in the field of cellular xenotransplantation. In this study, we review the work carried out in animal models that deals with the advantages and limitations of hepatocyte xenotransplantation, and we propose new studies needed in this field.

    The prevalence of non-alcoholic fatty liver disease (NAFLD) is increasing rapidly with the obesity and diabetes mellitus epidemics. It is rapidly becoming the most common cause of liver disease worldwide. NAFLD can progress to serious complications such as cirrhosis, hepatocellular carcinoma and death. Therefore, it is important to recognise this condition so that early intervention can be implemented. Lifestyle modifications and strict control of metabolic risk factors are the mainstay of treatment. As disease progression is slow in the majority of NAFLD patients, most can be managed well by primary care physicians. NAFLD patients with advanced liver fibrosis should be referred to specialist care for further assessment. PMID:27439352

This IRB approved study retrospectively reviewed patients requiring transplantation for cirrhosis, hepatocellular carcinoma (HCC, or both from 2003 to 2013. Records were reviewed identifying those having gadolinium enhanced MRI within 1 year of posttransplantation to document degree of liver disease, renal disease, and evidence for NSF. Results. Gadolinium-enhanced MRI was performed on 312 of 837 patients, including 23 with severe renal failure (GFR 30. Two of 23 patients with renal failure developed NSF compared to zero NSF cases in 289 patients with GFR > 30 (0/289; P<0.003. High dose gadodiamide was used in the two NSF cases. There was no increased incidence of NSF with severe liver disease (1/71 compared to nonsevere liver disease (1/241; P=0.412. Conclusion. Renal disease is a risk factor for NSF, but in our small sample our evidence suggests liver disease is not an additional risk factor, especially if a low-risk gadolinium agent is used. Noting that not all patients received high-risk gadolinium, a larger study focusing on patients receiving high-risk gadolinium is needed to further evaluate NSF risk in liver disease in the peritransplant period.

  3. Is transient elastography a useful tool for screening liver disease?

    Paolo Del Poggio; Silvia Colombo

    2009-01-01

    Transient elastography (TE) is a new non invasive tool for measuring liver stiffness, which is correlated to the histologic stage of liver fibrosis. Several studies in chronic liver disease (CLD) have determined a good accuracy of TE in predicting significant fibrosis and an optimal accuracy in predicting cirrhosis. Normal liver stiffness ranges between 3.3-7.8 KPa and using a cut off of 7.1 KPa, significant fibrosis and cirrhosis can be excluded with a very high negative predictive value (NPV). Positive predictive value (PPV) for the diagnosis of cirrhosis is lower using just a single scan but increases to 90% if high stiffness values are confirmed by a second independent scan. However the presence of fatty liver and metabolic syndrome slightly increases the readings and may reduce the accuracy of the test. It is uncertain if this increase is related to the presence of steatofibrosis or if it is caused by steatosis itself. TE can be used in screening patients attending the liver clinics to identify those with significant fibrosis or cirrhosis and may be particularly useful in discriminating HBV inactive carriers from chronic hepatitis B patients. TE, however, is not reliable in predicting the presence of esophageal varices in cirrhotics. Another potential indication for TE is the systematic screening of populations at high risk for CLD, such as intravenous drug users and alcoholics, but further studies are needed to determine its diagnostic accuracy in these settings.

    Noonan Syndrome (NS) is characterized by short stature, typical facial dysmorphology and congenital heart defects. The incidence of NS is estimated to be between 1:1000 and 1:2500 live births. The syndrome is transmitted as an autosomal dominant trait. In approximately 50% of cases, the disease is caused by missense mutations in the PTPN11 gene on chromosome 12, resulting in a gain of function of the non-receptor protein tyrosine phosphatase SHP-2 protein. Autoimmune Hepatitis (AIH) is a cryptogenic, chronic and progressive necroinflammatory liver disease. Common features of AIH are hypergammaglobulinemia (IgG), presence of circulating autoantibodies, histological picture of interface hepatitis and response to immunosuppressant drugs. Conventional treatment with Prednisone and Azathioprine is effective in most patients. We describe the case of a 6 years-old girl with Noonan Syndrome and Autoimmune Hepatitis type 1. Molecular analysis of PTPN11 gene showed heterozygous mutation c.923A>G (Asn308Ser) in exon 8. Though association between NS and autoimmune disorders is known, this is the second case of association between Noonan Syndrome and Autoimmune Hepatitis type 1 described in literature. In the management of NS, an accurate clinical evaluation would be recommended. When there is a clinical suspicion of autoimmune phenomena, appropriate laboratory tests should be performed with the aim of clarifying whether the immune system is involved in NS. We think that autoimmunity represents a characteristic of NS, even if the etiopathogenesis is still unknown.

    Full Text Available A doença hepática, alcoolismo e desnutrição são condições comumente associadas que interferem no metabolismo de micronutrientes. Como resultado da doença hepática pode ocorrer menor estocagem e conversão de vitaminas nas suas formas ativas, e má digestão e/ou má absorção. Há ainda o agravante do álcool diminuindo a ingestão e absorção de micronutrientes em virtude da redução da ingestão dietética e de sua associação com doença do intestino delgado ou pancreática. Outras causas de deficiências seriam: tratamento com drogas, peroxidação lipídica, déficit protéico, maior excreção urinária e aumento da necessidade e degradação de nutrientes. Como conseqüências dessas deficiências, esses pacientes apresentam usualmente anemia, esteatose hepática, estresse oxidativo e imunossupressão.Liver disease, alcohol and malnutrition are combinations usually associated with micronutrient impairment. Chronic liver disease courses with lower storage and activation of vitamin-coenzymes related to their malabsorption. Alcohol worsens the picture by reducing food intake, increasing micronutrients utilization and decreasing their absorption secondary to either intestinal or pancreatic injuries. Other concurrent causes would be drug treatments, urinary losses, protein deficiency and oxidative stress. As consequences the clinical signs are anemia, liver steatosis, oxidative stress and immunosuppression.

    Alcoholic liver disease (ALD) is a leading cause of morbidity and mortality worldwide. Alcoholic fatty liver disease can progress to steatohepatitis, alcoholic hepatitis, fibrosis, and cirrhosis. Patients with alcohol abuse show quantitative and qualitative changes in the composition of the intestinal microbiome. Furthermore, patients with ALD have increased intestinal permeability and elevated systemic levels of gut-derived microbial products. Maintaining eubiosis, stabilizing the mucosal gut barrier, or preventing cellular responses to microbial products protect from experimental ALD. Therefore, intestinal dysbiosis and pathological bacterial translocation appear fundamental for the pathogenesis of ALD. This review highlights causes for intestinal dysbiosis and pathological bacterial translocation, their relationship, and consequences for ALD. We also discuss how the liver affects the intestinal microbiota.

    Most of primary and secondary parasitic liver diseases, at present can be property treated with drugs. Venezuelan pharmaceutic market has some peculiarities that have determined the disappearance from the market of many drugs such as emetine, thiabendazole, quinacrine and niclosamide. Diloxanide never appeared. Venezuela has no commercial international treatises that protect international patents in the pharmaceutical area. In addition, government regulation of cost of drugs is very strict. This is particularly true with old drugs (such as emetine or quinacrine) which had such a low price that is non-commercial for the maker of the drug, usually a large transnational, and is withdrawn from the market. Flexibility of prices is quite easy for new antibiotics which are very expensive. Frequently small national companies import the drug from Italy and Japan which sell the drug independently from international treats. Such companies frequently produce the drug for the government social system, but are unreliable and also frequently they withdraw the drug a variable period of time. The government, through the Ministry of Public Health administer free treatment with drugs for malaria, tuberculosis and leprosy. The severe economic crisis of the country has severely impaired the preventive programs and there is an increase of malaria due to gold mining in the south of the country and falciparum chloroquine resistance and an increase of schistosomiasis in a previous free area. Also administration of drugs for malaria has been severely impaired, mainly for economic reasons. The establishment of a National Government Laboratory is an old (as far as 1946) political goal, but has remained in the political intention.(ABSTRACT TRUNCATED AT 250 WORDS)

    Full Text Available Nonalcoholic fatty liver disease (NAFLD is a common chronic liver disease that ranges in severity from simple steatosis to cirrhosis. NAFLD is considered to be associated with hepatic metabolic disorders, resulting in overaccumulation of fatty acids/triglycerides and cholesterol. The pathogenesis and progression of NAFLD are generally explained by the “two-hit theory.” Most studies of lipid metabolism in the NAFLD liver have focused on the metabolism of fatty acids/triglycerides; therefore, the impact of cholesterol metabolism is still ambiguous. In this paper, we review recent studies on NAFLD from the viewpoint of hepatic lipid metabolism-associated factors and discuss the impact of disordered cholesterol metabolism in the etiology of NAFLD. The clinical significance of managing cholesterol metabolism, an option for the treatment of NAFLD, is also discussed.

    On chronic supply to the body of a mixture of nuclear division products lanthanum-140, barium-140, tellurium-132, neodymium-147, neptunium-239, zirconium-95, niobium-95, iodine-131, cerium-141, -144, cesium-134, -137, and ruthenium-103 are detectable in liver tissue within the first months. In the 2 to 4 years following the disaster, liver tissue primarily accumulates cerium-144, radium-226, thorium-228, -232, ruthenium-106, antimony-125, and europium-154. Within the first periods the liver radionuclide content was 19 to 31% higher than that in the blood, and in the following years it was 24 to 38% higher. The radionuclides indicated were actively excreted with the bile into the gastrointestinal lumen. Within the first months after the chronic internal radiation the functional liver disorders were detectable in 30 to 40% of the patients. Later on diverse acute and chronic diseases of the liver, gallbladder and pancreas were detectable in 20 to 30% of the patients. The radionuclide content in the body was found to be in parallel with functional liver disorders. Acceleration of radionuclide excretion from the body results in liver function improvement.

It is regulated on several levels, with different cellular populations contributing to this process, eg, hepatocytes, liver precursor cells, intrahepatic stem cells. In response to injury, mature hepatocytes have the capability to proliferate and give rise to new hepatocytes and cholangiocytes. Meanwhile, liver precursor cells (oval cells have become the most recognized bipotential precursor cells in the damaged liver. They rapidly proliferate, change their cellular composition, and differentiate into hepatocytes and cholangiocytes to compensate for the cellular loss and maintain liver homeostasis. There is a growing body of evidence that oval cells originate from the intrahepatic stem cell(s, which in turn give(s rise to epithelial, including oval cells, and/or other hepatic cells of nonepithelial origin. Since there is a close relationship between the liver and hematopoiesis, bone marrow derived cells can also contribute to liver regeneration by the fusion of myeloid cells with damaged hepatocytes, or differentiation of mesenchymal stem cells into hepatocyte-like cells. The current review discusses the contribution of different cells to liver regeneration and their characteristics.Keywords: hepatic progenitor, liver disease, liver precursor cells, oval cells, hepatocytes, intrahepatic stem cells, cholangiocytes

    Within living memory of some of us, liver disease was a Cinderella subject. If you look up the first edition of the standard medical textbook of the time, Sir William Osler's 'Principles and Practice of Medicine', published in 1892, you will find a mere 24 of its 1079 pages devoted to the liver, compared with 38 pages on typhoid fever alone; and matters hardly changed throughout the first half of the 20th century. Although 'cirrhosis' and 'hepatitis' were well recognised conditions when I was a house surgeon in 1948, their classification, aetiologies, detailed pathology and management were little understood, while laboratory investigations of the liver diseases were few and non-specific.

    Full Text Available Introduction. Nitrofurantoin, a furan derivative, introduced in the fifties has widely been used as an effective agent for the treatment and prevention of urinary tract infections (UTI. Spectrum of adverse reactions to nitrofurantoin is wide, ranging from eosinophilic interstitial lung disease, acute hepatitis and granulomatous reaction, to the chronic active hepatitis, a very rare adverse effect, that can lead to cirrhosis and death. Case report. We presented a 55-year-old female patient with eosinophilic interstitial lung disease, severe chronic active hepatitis and several other immune- mediated multisystemic manifestations of prolonged exposure to nitrofurantoin because of the recurrent UTI caused by Escherichia coli. We estimated typical radiographic and laboratory disturbances, also restrictive ventilatory changes, severe reduction of carbon monoxide diffusion capacity and abnormal liver function tests. Lymphocytic-eosinophylic alveolitis was consistent with druginduced reaction. Hepatitis was confirmed by liver biopsy. After withdrawal of nitrofurantoin and application of high dose of glicocorticosteroids, prompt clinical and laboratory recovery was achieved. Conclusion. Adverse drug reactions should be considered in patients with concomitant lung and liver disease. The mainstay of treatment is drug withdrawal and the use of immunosuppressive drugs in severe cases. Consideration should be given to monitor lung and liver function tests during long term nitrofurantoin therapy.

    In recent years, nonalcoholic fatty liver disease (NAFLD) has increased because of the growing prevalence of obesity and overweight in the pediatric population. It has become the most common form of chronic liver diseases in children and the related research on NAFLD is expanded. The "two-hit" and "multiple hit" hypothesis have been widely accepted, and some research has shown that genetic, diet structure and environmental factors appear to play a crucial role in the development of pediatric NAFLD. Though it is expected by researchers, there is not an available satisfactory noninvasive marker for the diagnosis of this disease. Fortunately, some new non-invasive prediction scores for pediatric NAFLD have been developed. There is currently no established special therapy, and lifestyle intervention should be adequate for most cases of NAFLD in children. This article reviews the advances in the current knowledge and ideas concerning pediatric NAFLD, and discusses the diagnosis, perspective therapies and scoring methods for this disease.

    Non-alcoholic fatty liver disease (NAFLD) is a chronic liver disease that refers to the presence of hepatic steatosis without significant intake of alcohol. NAFLD is an asymptomatic disease that can progress to nonalcoholic steatohepatitis (NASH), fibrosis, cirrhosis, and hepatocellular carcinoma. The most common cause of mortality in patients with NAFLD or NASH is cardiovascular disease (CVD). Currently, the treatment of NAFLD focuses on gradual weight loss and life style modifications. However, multifactorial treatment of NAFLD or NASH risk factors may be needed to reduce the likelihood of these patients developing CVD. This review discusses the mechanisms that link hyperlipidemia and NAFLD. In addition, the review focuses on the safety and efficacy of statins in patients with NAFLD or NASH, and their effect on the extent of hepatic steatosis and fibrosis based on human studies.

    Background Alpha1 anti-trypsin (α1-AT), a serine protease inhibitor synthesized in the liver, is a major circulating antiprotease that provides defense against proteolytic damage in several tissues. Its deficiency is associated with airflow obstruction. The present study aimed to explore the role of α1-AT as a biomarker of airflow performance in chronic liver disease (CLD). Material/Methods Serum α1-AT levels and lung function (spirometry) were evaluated in non-primary α1-AT-deficient, alcoholic CLD patients without evident respiratory limitations. Results Thirty-four patients with airflow obstruction (n=11), airflow restriction (n=12), and normal airflow (n=11, age-matched controls) were eligible. α1-AT was decreased in the airflow obstruction group. ROC-cutoff α1-AT=24 mg/dL effectively discriminated airflow obstruction (AUC=0.687) and was associated with a 10-fold higher risk (p=0.0007). Conclusions Lower α1-AT increased the risk of airflow obstruction in CLD patients without primary α1-AT deficiency. PMID:25913248

    Objective:To investigate the clinical value of ultrasonic imaging in the assessment of liver fibrosis in patients with chronic hepatitis B. Methods:A total of 20 cases of liver biopsy in chronic hepatitis B, according to the degree of hepatic fibrosis were divided into mild hepatic fibrosis group, moderate fibrosis group, severe fibrosis group, the other selected healthy volunteers as control group, using color Doppler ultrasound, the use of imaging technology and automatic tracking. Strengthen the quantitative analysis, using the second generation microbubble contrast agent SonoVue contrast analysis, contrast agent reach the portal time (PVAT), hepatic artery time (HAAT), hepatic vein (HVVT), the calculation time of hepatic arteriovenous transit time (VAT) and hepatic portal vein transit time (VVT), using chemiluminescence detection of serum liver fiber hyaluronic acid (HA), laminin (LN) and collagen type IV (CIV) index. Results:there was no significant difference in HAAT, PVAT, VAT, VVT and HVAT in all groups, and there was no significant difference, mild, moderate and severe liver fibrosis group, and HA, LN and C levels were significantly higher than those in control group. Conclusion:serum liver fibrosis indexes can guide the degree of liver fibrosis. The ultrasound contrast can reflect the changes of liver blood flow dynamics, and it has a certain guiding significance to the assessment of the degree of liver fibrosis, the monitoring of the disease and the clinical treatment.

    AIM: To evaluate the glycated hemoglobin (HbA1c)determination methods and to determine fructosamine in patients with chronic hepatitis, compensated cirrhosis and in patients with chronic hepatitis treated with ribavirin.METHODS: HbA1c values were determined in 15 patients with compensated liver cirrhosis and in 20 patients with chronic hepatitis using the ion-exchange high performance liquid chromatography and the immunoassay methods.Fructosamine was determined using nitroblue tetrazolium.RESULTS: Forty percent of patients with liver cirrhosis had HbA1c results below the non-diabetic reference range by at least one HbA1c method, while fructosamine results were either within the reference range or elevated. Twenty percent of patients with chronic hepatitis (hepatic fibrosis)had HbA1c results below the non-diabetic reference range by at least one HbA1c method. In patients with chronic hepatitis treated with ribavirin, 50% of HbA1c results were below the non-diabetic reference using at least one of the HbA1c methods.CONCLUSION: Only evaluated in context with all liver function parameters as well as a red blood count including reticulocytes, HbA1c results should be used in patients with advanced liver disease. HbA1c and fructosamine measurements should be used with caution when evaluating long-term glucose control in patients with hepatic cirrhosis or in patients with chronic hepatitis and ribavirin treatment.

  2. Acute renal dysfunction in liver diseases

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Renal dysfunction is common in liver diseases, either as part of multiorgan involvement in acute illness or secondary to advanced liver disease. The presence of renal impairment in both groups is a poor prognostic indicator. Renal failure is often multifactorial and can present as pre-renal or intrinsic renal dysfunction. Obstructive or post renal dysfunction only rarely complicates liver disease. Hepatorenal syndrome (MRS) is a unique form of renal failure associated with advanced liver disease or cirrhosis, and is characterized by functional renal impairment without significant changes in renal histology. Irrespective of the type of renal failure, renal hypoperfusion is the central pathogenetic mechanism, due either to reduced perfusion pressure or increased renal vascular resistance. Volume expansion, avoidance of precipitating factors and treatment of underlying liver disease constitute the mainstay of therapy to prevent and reverse renal impairment. Splanchnic vasoconstrictor agents, such as terlipressin, along with volume expansion, and early placement of transjugular intrahepatic portosystemic shunt (TIPS) may be effective in improving renal function in HRS. Continuous renal replacement therapy (CRRT) and molecular absorbent recirculating system (MARS) in selected patients may be life saving while awaiting liver transplantation.

    Xiang Li

    Full Text Available Gadoxetic acid disodium (Gd-EOB-DTPA is a magnetic resonance imaging (MRI contrast agent to target the liver cells with normal function. In clinical practice, the Gd-EOB-DTPA produces high quality hepatocyte specific image 20 minutes after intravenous injection, so DWI sequence is often performed after the conventional dynamic scanning. However, there are still some disputes about whether DWI sequence will provide more effective diagnostic information in clinical practice. This study aimed to explore the diagnostic value of combining Gd-EOB-DTPA-enhanced MRI and DWI in the detection of hepatocellular carcinoma (HCC in patients with chronic liver disease.A systematic literature search was performed in the PubMed and Cochrane library database up to March 2015. The quality assessment of diagnostic accuracy studies (QUADAS was used to evaluate the quality of studies. Heterogeneous test on the included literature was performed by using the software Review Manager 5.3. The MetaDiSc 1.4 software was used to calculate the pooled sensitivity, specificity, positive likelihood ratio and negative likelihood ratio; meanwhile the summary receiver operating characteristics (SROC curve was drawn to compare the diagnostic performance.A total of 13 literatures were included in this study. In 8 literatures regarding HCC diagnosis based on Gd-EOB-DTPA-enhanced MRI, the pooled sensitivity: 0.90 (95% confidence interval (CI: 0.88-0.93; specificity: 0.89 (95% CI: 0.85-0.92; positive likelihood ratio: 8.60 (95% CI: 6.20-11.92; negative likelihood ratio: 0.10 (95% CI: 0.08-0.14 were obtained. The area under curve (AUC and Q values were 0.96 and 0.90, respectively. In 5 literatures relating to HCC diagnosis by combination of Gd-EOB-DTPA-enhanced MRI and DWI sequence, the pooled sensitivity: 0.88 (95% CI: 0.85-0.91, specificity: 0.96 (0.94-0.97, positive likelihood ratio: 19.63 (12.77-30.16, negative likelihood ratio: 0.10 (0.07-0.14 were obtained.

    Highlights: •We investigated imaging findings on gadoxetic acid-enhanced MRI of HCCs without the typical enhancement pattern on multiphasic MDCT. •Most HCCs showed ancillary MR findings of typical HCC. •Considerable number of HCCs showed MR enhancement pattern of typical HCC. -- Abstract: Objective: The purpose of this study was to investigate the value of enhancement kinetics and ancillary imaging findings on gadoxetic acid-enhanced and diffusion-weighted (DW) MR imaging for diagnosing hepatocellular carcinomas (HCCs) without the typical enhancement pattern on contrast-enhanced multiphasic MDCT in patients with chronic liver disease. Materials and methods: Eighty-two surgically confirmed HCCs without the typical enhancement pattern (hypervascular in the arterial phase, followed by washout on the portal or equilibrium phases) on triple-phase MDCT were enrolled in this study. The patients were classified into four categories based on the CT density pattern of arterial and equilibrium phases (isodense–isodense, hypodense–hypodense, isodense–hypodense, and hyperdense–isodense) compared to liver parenchyma. Signal intensity of HCCs on T2-weighted images (T2WI), arterial phase, 3 min late-phase, hepatobiliary phase (HBP) and DW images with a b value of 800 s/mm{sup 2} were qualitatively evaluated, and ADC values were measured. Fisher's exact test and Chi-square test were used to compare the frequency and trend of hyperintensity on T2WI, hypointensity on HBP images, hyperintensity on DW images, and histopathologic grades between groups with different CT density patterns. Kruskal–Wallis test was used to compare the ADC value between groups. Results: Thirty and 52 HCCs were categorized as hypervascular (hyperdense–isodense) and non-hypervascular HCCs (3, isodense–isodense; 37, hypodense–hypodense; 12, isodense–hypodense), respectively. Most HCCs showed hyperintensity on T2WI (77/82, 93.9%) and DW images (81/82, 98.8%) and hypointensity on HBP

    Chronic non-communicable disease is a major public health problem affecting the health of residents in china. Evidence shows that, in addition to four major risk factors, i.e. unreasonable dietary, lack of physical activity, smoking and drinking, epidemic and severe outcome of chronic disease is associated with many infectious diseases. Increasingly cancers have been shown to have an infectious etiology. There is also a significantly increased risk of infectious disease such as influenza, pneumonia and other infectious disease in people with pre-existing chronic non-communicable diseases like diabetes, heart disease, and lung diseases. And more than that, there is a high risk of susceptibility to death and severe outcomes among them. Epidemiological studies has confirmed, that through targeted vaccine inoculation, liver cancer, cervical cancer can be effectively prevented, while influenza or pneumonia vaccine are related to reduced risk of hospitalization or death and hospitalization expenses regarding with a variety of chronic diseases. World Health Organization and several other professional organizations have put forward recommendations on vaccine inoculation of chronic disease patients. Programs targeting infectious factors are also an important aspect of chronic diseases prevention and control, therefore, related researches need to be strengthened in the future.

    Studies have shown that most patients diagnosed with chronic Lyme disease either have no objective evidence of previous or current infection with Borrelia burgdorferi or are patients who should be classified as having post-Lyme disease syndrome, which is defined as continuing or relapsing nonspecific symptoms (such as fatigue, musculoskeletal pain, and cognitive complaints) in a patient previously treated for Lyme disease. Despite extensive study, there is currently no clear evidence that post-Lyme disease syndrome is caused by persistent infection with B burgdorferi. Four randomized placebo-controlled studies have shown that antibiotic therapy offers no sustained benefit to patients who have post-Lyme disease syndrome. These studies also showed a substantial placebo effect and a significant risk of treatment-related adverse events. Further research to elucidate the mechanisms underlying persistent symptoms after Lyme disease and controlled trials of new approaches to the treatment and management of these patients are needed.

    A group of patients between 35 and 65 years old with chronic prostatitis were examined for the presence of Becherew's disease. In this connection the New York and Roman criterions for morbus Bechterew were applied. There were found one ankyosing spondylarthritis, one ankylosis of the sacroiliac joint, and 11 times a tentative sacroileitis were stated. Altogether the proved and tentative findings were only 3.68 per cent of all examinations. In our countries the morbus Bechterew is found in 0,21 per cent of the normal population. So the protion of the Bechterew's disease in patients with chronic prostatitis is indeed a little higher than average, but not so frequent as often pretended in recent times. After a second series 58 patients being treated because of Bechterew's disease of different stages and different terms were examined for the possibility of a simultaneously elapsing chronic prostatitis. A chronic prostatitis was found in 38 per cent of these patients which correspondents to the incidence published in literature for the medium-age manhood. Nobody of the test persons had complaints on the part of the urologenital tract.

    The aim of this study was to evaluate the effect of liver diseases of different etiologies and clinical severity of liver cirrhosis on the serum level of hyaluronic acid. The results were compared with noninvasive markers of liver fibrosis: APRI, GAPRI, HAPRI, FIB-4 and Forn's index. Serum samples were obtained from 20 healthy volunteers and patients suffering from alcoholic cirrhosis (AC)-57 patients, non-alcoholic cirrhosis (NAC)-30 and toxic hepatitis (HT)-22. Cirrhotic patients were classified according to Child-Pugh score. Hyaluronic acid concentration was measured by the immunochemical method. Non-patented indicators were calculated using special formulas. The mean serum hyaluronic acid concentration was significantly higher in AC, NAC and HT group in comparison with the control group. There were significant differences in the serum hyaluronic acid levels between liver diseases, and in AC they were significantly higher than those in NAC and HT group. The serum hyaluronic acid level differs significantly due to the severity of cirrhosis and was the highest in Child-Pugh class C. The sensitivity, specificity, accuracy, positive and negative predictive values and the area under the ROC curve for hyaluronic acid and all non-patented algorithms were high and similar to each other. We conclude that the concentration of hyaluronic acid changes in liver diseases and is affected by the severity of liver cirrhosis. Serum hyaluronic acid should be considered as a good marker for noninvasive diagnosis of liver damage, but the combination of markers is more useful.

    2008-07-01

    There is much controversy about the treatment of Lyme disease with respect to 2 poorly defined entities: "chronic Lyme disease" and "posttreatment Lyme disease syndrome." In the absence of direct evidence that these conditions are the result of a persistent infection, some mistakenly advocate extended antibiotic therapy (>/=6 months), which can do great harm and has resulted in at least 1 death. The purpose of this brief report is to review what is known from clinical research about these conditions to assist both practicing physicians and lawmakers in making sound and safe decisions with respect to treatment.

    Full Text Available BACKGROUND AND AIMS: Genetic polymorphisms near interleukin 28B gene are associated with spontaneous and treatment induced clearance of hepatitis C virus (HCV. Our objective was to evaluate the impact of interleukin 28B single nucleotide polymorphism (rs12979860, rs8099917 variability in HCV genotype 3 infected populations. METHODS: 400 hepatitis C seroreactive patients from different population groups in Eastern and North Eastern part of India were assessed for host and viral genotypic analysis. 83 HCV genotype 3 infected patients were administered pegylated interferon- ribavirin therapy. Viral genotyping was performed using nested reverse transcriptase-PCR followed by direct sequencing methods. Host interleukin 28B genotyping was performed using real-time PCR based single nucleotide polymorphism analysis. RESULTS: Out of 400 hepatitis C seroreactive individuals, 73.25% were found to be RNA positive. HCV genotype 3 (65.87% was found to be the major circulating strain in this region followed by genotype 1 (32.08%. rs12979860 CC genotype was significantly associated with sustained virological response in HCV genotype 3 infected population. In patients achieving rapid virological response, favourable CC/TT allele at rs12979860, rs8099917 was found to be predominant at both the alleles at 77%, 73.2% respectively; whereas in case of patients with relapsed HCV infection CT, TG alleles were found to be predominant. Additionally, CC genotypes at rs12979860 were found to be associated with sustained virological response in patients with high viral load (OR = 6.75, 0.05liver disease. CONCLUSION: CC, TT the two favourable markers at SNPs rs12979860 and rs8099917 are strongly associated with sustained virological response

    Full Text Available It is easier to prevent a disease than to cure it. This postulate is a foundation stone of the contemporary medicine, furthermore its mission. The Chronic Kidney Diseases (CKD, amongst them the Chronic Pyelonephrites (CP and the mass kidney reduction  take an important  place in human pathologies in general, and in particular in renal ones. The Chronic Pyelonephrites  are chronic renal pathologies, which on one side are of various causes and on the other side are multi systemic. At the same time they tend, earlier or later, depending on their course, to bring the patient towards the Chronic Kidney Insufficiency  in stage of uremia, consequently in need of substitution therapies e.g. dialysis, peritoneum dialysis or transplant. It is worthy to emphasize that from the prevention and correct cure of CP make profit the patients, the family, the state and in the last analyses  the entire society, because in that way the budget expense destined for the fore going substitution cures, dialysis, peritoneum dialysis or transplant, is considerably  reduced. The same should be mentioned  in relation to the CP and the mass kidney reduction, speaking about our country, which are still at the first place as the very cause of Chronic Kidney  Insufficiencies (CRI, later on advancing toward uremia and terminal uremia along with its grave consequences. In general  the very foundation of the CP is on  the  infections of urinary roads, in particular on the complicated ones, among them it should be mentioned-congenital kidney anomalies, renal calculosis  so much present in our country, and pathologies of segment or vesical-ureteral reflux, and rarely the pathologies of prostate.

    Fibrosis is characterized by extracellular matrix (ECM) remodeling and stiffening. However, the functional contribution of tissue stiffening to noncancer pathogenesis remains largely unknown. Fibronectin (Fn) is an ECM glycoprotein substantially expressed during tissue repair. Here we show in advanced chronic liver fibrogenesis using a mouse model lacking Fn that, unexpectedly, Fn-null livers lead to more extensive liver cirrhosis, which is accompanied by increased liver matrix stiffness and deteriorated hepatic functions. Furthermore, Fn-null livers exhibit more myofibroblast phenotypes and accumulate highly disorganized/diffuse collagenous ECM networks composed of thinner and significantly increased number of collagen fibrils during advanced chronic liver damage. Mechanistically, mutant livers show elevated local TGF-β activity and lysyl oxidase expressions. A significant amount of active lysyl oxidase is released in Fn-null hepatic stellate cells in response to TGF-β1 through canonical and noncanonical Smad such as PI3 kinase-mediated pathways. TGF-β1-induced collagen fibril stiffness in Fn-null hepatic stellate cells is significantly higher compared with wild-type cells. Inhibition of lysyl oxidase significantly reduces collagen fibril stiffness, and treatment of Fn recovers collagen fibril stiffness to wild-type levels. Thus, our findings indicate an indispensable role for Fn in chronic liver fibrosis/cirrhosis in negatively regulating TGF-β bioavailability, which in turn modulates ECM remodeling and stiffening and consequently preserves adult organ functions. Furthermore, this regulatory mechanism by Fn could be translated for a potential therapeutic target in a broader variety of chronic fibrotic diseases.

    Nonalcoholic fatty liver disease (NAFLD) encompasses a range of liver histology severity and outcomes in the absence of chronic alcohol use. The mildest form is simple steatosis in which triglycerides accumulate within hepatocytes. A more advanced form of NAFLD, nonalcoholic steatohepatitis, includes inflammation and liver cell injury, progressive to cryptogenic cirrhosis. NAFLD has become the most common cause of chronic liver disease in children and adolescents. The recent rise in the prevalence rates of overweight and obesity likely explains the NAFLD epidemic worldwide. NAFLD is strongly associated with abdominal obesity, type 2 diabetes, and dyslipidemia, and most patients have evidence of insulin resistance. Thus, NAFLD shares many features of the metabolic syndrome (MetS), a highly atherogenic condition, and this has stimulated interest in the possible role of NAFLD in the development of atherosclerosis. Accumulating evidence suggests that NAFLD is associated with a significantly greater overall mortality than in the general population, as well as with increased prevalence of cardiovascular disease (CVD), independently of classical atherosclerotic risk factors. Yet, several studies including the pediatric population have reported independent associations between NAFLD and impaired flow-mediated vasodilatation and increased carotid artery intimal medial thickness-two reliable markers of subclinical atherosclerosis-after adjusting for cardiovascular risk factors and MetS. Therefore, the rising prevalence of obesity-related MetS and NAFLD in childhood may lead to a parallel increase in adverse cardiovascular outcomes. In children, the cardiovascular system remains plastic and damage-reversible if early and appropriate interventions are established effectively. Therapeutic goals for NAFLD should address nutrition, physical activity, and avoidance of smoking to prevent not only end-stage liver disease but also CVD.

  20. Circulating extracellular vesicles with specific proteome and liver microRNAs are potential biomarkers for liver injury in experimental fatty liver disease.

    Directory of Open Access Journals (Sweden)

    Davide Povero

    Full Text Available BACKGROUND & AIM: Nonalcoholic fatty liver disease (NAFLD is the most common chronic liver disease in both adult and children. Currently there are no reliable methods to determine disease severity, monitor disease progression, or efficacy of therapy, other than an invasive liver biopsy. DESIGN: Choline Deficient L-Amino Acid (CDAA and high fat diets were used as physiologically relevant mouse models of NAFLD. Circulating extracellular vesicles were isolated, fully characterized by proteomics and molecular analyses and compared to control groups. Liver-related microRNAs were isolated from purified extracellular vesicles and liver specimens. RESULTS: We observed statistically significant differences in the level of extracellular vesicles (EVs in liver and blood between two control groups and NAFLD animals. Time-course studies showed that EV levels increase early during disease development and reflect changes in liver histolopathology. EV levels correlated with hepatocyte cell death (r2 = 0.64, p<0.05, fibrosis (r2 = 0.66, p<0.05 and pathological angiogenesis (r2 = 0.71, p<0.05. Extensive characterization of blood EVs identified both microparticles (MPs and exosomes (EXO present in blood of NAFLD animals. Proteomic analysis of blood EVs detected various differentially expressed proteins in NAFLD versus control animals. Moreover, unsupervised hierarchical clustering identified a signature that allowed for discrimination between NAFLD and controls. Finally, the liver appears to be an important source of circulating EVs in NAFLD animals as evidenced by the enrichment in blood with miR-122 and 192--two microRNAs previously described in chronic liver diseases, coupled with a corresponding decrease in expression of these microRNAs in the liver. CONCLUSIONS: These findings suggest a potential for using specific circulating EVs as sensitive and specific biomarkers for the noninvasive diagnosis and monitoring of NAFLD.

    AIM: To select valuable ultrasonographic predictors for the evaluation of hepatic inflammation and fibrosis degree in chronic hepatitis, and to study the value of ultrasonography in the evaluation of liver fibrosis and compensated liver cirrhosis in comparison with serology and histology.METHODS: Forty-four ultrasonographic variables were analyzed and screened using color Doppler ultrasound system in 225 patients with chronic viral hepatitis and compensated liver cirrhosis. The valuable ultrasonographic predictors were selected on the basis of a comparison with histopathological findings. The value of ultrasonography and serology in the evaluation of liver fibrosis degree and the diagnosis of compensated liver cirrhosis was also studied and compared. Meanwhile, the influencing factors on ultrasonographic diagnosis of compensated liver cirrhosis were also analyzed.RESULTS: By statistical analysis, the maximum velocity of portal vein and the degree of gall-bladder wall smoothness were selected as the valuable predictors for the inflammation grade (G), while liver surface, hepatic parenchymal echo pattern, and the wall thickness of gall-bladder were selected as the valuable predictors for the fibrosis stage (S). Three S-related independent ultrasonographyic predictors and three routine serum fibrosis markers (HA, HPCIII and CIV) were used to discriminate variables for the comparison of ultrasonography with serology. The diagnostic accuracy of ultrasonography in moderate fibrosis was higher than that of serology (P<0.01), while there were no significant differences in the general diagnostic accuracy of fibrosis as well as between mild and severe fibrosis (P<0.05). There were no significant differences between ultrasonography and serology in the diagnosis of compensated liver cirrhosis.However, the diagnostic accuracy of ultrasonography was higher in inactive liver cirrhosis and lower in active cirrhosis than that of serology (both P<0.05).

    This paper explores the economic implications of vouchers for chronic disease management with respect to achieving objectives of equity and efficiency. Vouchers as a payment policy instrument for health care services have a set of properties that suggest they may address both demand-side and supply-side issues, and contribute to equity and efficiency. They provide a means whereby health care services can be targeted at selected groups, enabling consumer choice of provider, and encouraging competition in the supply of health services. This analysis suggests that, when structured appropriately, vouchers can support consumers to choose services that will meet their health care needs and encourage competition among providers. Although they may not be appropriate across the entire health care system, there are features of vouchers that make them a potentially attractive option, especially for the management of chronic disease.

    2016-01-01

    Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease. It is characterized by a wide spectrum of hepatic changes, which may progress to non-alcoholic steatohepatitis (NASH) and cirrhosis. NAFLD is considered a hepatic manifestation of metabolic syndrome; however, mechanisms underlying the onset and progression of NAFLD are still unclear. Resident and recruited macrophages are key players in the homeostatic function of the liver and in the progression of NAFLD to NASH. Progress has been made in understanding the molecular mechanisms underlying the polarized activation of macrophages. New NAFLD therapies will likely involve modification of macrophage polarization by restraining M1 activation or driving M2 activation. Carotenoids are potent antioxidants and anti-inflammatory micronutrients that have been used to prevent and treat NAFLD. In addition to their antioxidative action, carotenoids can regulate macrophage polarization and thereby halt the progression of NASH. In this review, we summarize the molecular mechanisms of macrophage polarization and the function of liver macrophages/Kupffer cells in NAFLD. From our review, we propose that dietary carotenoids, such as β-cryptoxanthin and astaxanthin, be used to prevent or treat NAFLD through the regulation of macrophage polarization and liver homeostasis.

    Liver disease results in over four million physician visits and over 750,000 hospitalizations per year in the USA. Those with chronic liver disease frequently progress to cirrhosis, end-stage liver disease (ESLD), and death. Patients with ESLD experience numerous complications, including muscle cramps, confusion (hepatic encephalopathy), protein calorie malnutrition, muscle wasting, fluid overload (ascites, edema), bleeding (esophagogastric variceal hemorrhage), infection (spontaneous bacterial peritonitis), fatigue, anxiety, and depression. Despite significant improvements in palliation of these complications, patients still suffer reduced quality of life and must confront the fact that their disease will often inexorably progress to death. Liver transplantation is a valid option in this setting, increasing the duration of survival and palliating many of the symptoms. However, many patients die waiting for an organ or are not candidates for transplantation due to comorbid illness. Others receive a transplant but succumb to complications of the transplant itself. Patients and families must struggle with simultaneously hoping for a cure while facing a life-threatening illness. Ideally, the combination of palliative care with life-sustaining therapy can maximize the patients' quality and quantity of life. If it becomes clear that life-sustaining therapy is no longer an option, these patients are then already in a system to help them with end-of-life care.

    Fibronectins are adhesive glycoproteins that can be found in tissue matrices and circulating in various fluids of the body. The variable composition of fibronectin molecules facilitates a diversity of interactions with cell surface receptors that suggest a role for these proteins beyond the structural considerations of the extracellular matrix. These interactions implicate fibronectin in the regulation of mechanisms that also determine cell behavior and activity. The two major forms, plasma fibronectin (pFn) and cellular fibronectin (cFn), exist as balanced amounts under normal physiological conditions. However, during injury and/or disease, tissue and circulating levels of cFn become disproportionately elevated. The accumulating cFn, in addition to being a consequence of prolonged tissue damage, may in fact stimulate cellular events that promote further damage. In this review, we summarize what is known regarding such interactions between fibronectin and cells that may influence the biological response to injury. We elaborate on the effects of cFn in the liver, specifically under a condition of chronic alcohol-induced injury. Studies have revealed that chronic alcohol consumption stimulates excess production of cFn by sinusoidal endothelial cells and hepatic stellate cells while impairing its clearance by other cell types resulting in the build up of this glycoprotein throughout the liver and its consequent increased availability to influence cellular activity that could promote the development of alcoholic liver disease. We describe recent findings by our laboratory that support a plausible role for cFn in the promotion of liver injury under a condition of chronic alcohol abuse and the implications of cFn stimulation on the pathogenesis of alcoholic liver disease. These findings suggest an effect of cFn in regulating cell behavior in the alcohol-injured liver that is worth further characterizing not only to gain a more comprehensive understanding of the role this

    Full Text Available We investigated the impact of chronic hypercorticosteronemia (due to neonatal monosodium L-glutamate, MSG, and treatment on liver oxidative stress (OS, inflammation, and carbohydrate/lipid metabolism in adult male rats. We evaluated the peripheral concentrations of several metabolic and OS markers and insulin resistance indexes. In liver we assessed (a OS (GSH and protein carbonyl groups and inflammatory (IL-1b, TNFa, and PAI-1 biomarkers and (b carbohydrate and lipid metabolisms. MSG rats displayed degenerated optic nerves, hypophagia, low body and liver weights, and enlarged adipose tissue mass; higher peripheral levels of glucose, triglycerides, insulin, uric acid, leptin, corticosterone, transaminases and TBARS, and peripheral and liver insulin resistance; elevated liver OS, inflammation markers, and glucokinase (mRNA/activity and fructokinase (mRNA. Additionally, MSG liver phosphofructokinase-2, glucose-6-phosphatase (mRNA and activity and glucose-6-phosphate dehydrogenase, Chrebp, Srebp1c, fatty acid synthase, and glycerol-3-phosphate (mRNAs were increased. In conclusion adult MSG rats developed an insulin-resistant state and increased OS and serious hepatic dysfunction characterized by inflammation and metabolic signs suggesting increased lipogenesis. These features, shared by both metabolic and Cushing’s syndrome human phenotypes, support that a chronic glucocorticoid-rich endogenous environment mainly impacts on hepatic glucose cycle, displacing local metabolism to lipogenesis. Whether correcting the glucocorticoid-rich environment ameliorates such dysfunctions requires further investigation.

    Nonalcoholic fatty liver disease (NAFLD) is the primary cause of chronic liver disease in the United States, afflicting an estimated 80 to 100 million Americans. Nonalcoholic fatty liver disease is a spectrum of liver diseases composed of nonalcoholic fatty liver and nonalcoholic steatohepatitis (NASH). Although nonalcoholic fatty liver has a negligible risk of progression, patients with NASH often develop cirrhosis or hepatocellular carcinoma. Although liver biopsy is required to diagnose NASH, only patients with a high risk of NASH or advanced fibrosis require this evaluation. Despite the high prevalence of NAFLD, well-defined screening recommendations are currently lacking. In this review, suggestions for screening, diagnosis, and initial work-up of NAFLD are given on the basis of established guidelines and recent publications. Proposed drug treatments of NASH are also discussed, highlighting the study outcomes, as well as proposed uses and limitations of these drugs. The literature was searched in PubMed using search terms nonalcoholic fatty liver disease and nonalcoholic steatohepatitis, with filters of "English language." A date range of January 1, 2000, to May 1, 2015, was used for the search. The bibliographies of key references were also searched manually, and seminal publications before the year 2000 were included.

    Numerous lines of evidence implicate a role of myeloperoxidase (MPO) in the pathogenesis of cardiovascular disease (CVD). It is a well accepted fact that patients with chronic kidney disease (CKD) are at an increased risk for CVD. MPO is a pro-oxidant enzyme which could be involved in the increased susceptibility of these patients to CVD. Hence, the levels of plasma MPO was determined in healthy controls as well as in patients with CKD [stratified with the level of their kidney failure as CKD...

    Full Text Available BACKGROUND: High score of model for end-stage liver diseases (MELD before liver transplantation (LT indicates poor prognosis. Artificial liver support system (ALSS has been proved to effectively improve liver and kidney functions, and thus reduce the MELD score. We aim to evaluate whether downgrading MELD score could improve patient survival after LT. METHODOLOGY/PRINCIPAL FINDINGS: One hundred and twenty-six LT candidates with acute-on-chronic hepatitis B liver failure and MELD score ≥30 were included in this prospective study. Of the 126 patients, 42 received emergency LT within 72 h (ELT group and the other 84 were given ALSS as salvage treatment. Of the 84 patients, 33 were found to have reduced MELD score (40 years and the interval from last ALSS to LT >48 h were independent negative influence factors of downgrading MELD. CONCLUSIONS/SIGNIFICANCE: Downgrading MELD for liver trans
