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

    Directory of Open Access Journals (Sweden)

    Stephanie C Burke Schinkel

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

    Full Text Available BACKGROUND Regular monitoring of serum iron parameters is helpful for assessing the severity of alcoholic liver disease. Assessment of serum iron parameters are used for screening hereditary haemochromatosis in chronic liver disease. Serum iron parameters in chronic liver disease have not been clearly described in most of the studies. The aim of this study was to assess the serum iron, Total Iron Binding Capacity (TIBC, transferrin saturation and ferritin levels in common chronic liver disease like alcoholic cirrhosis, cryptogenic cirrhosis, chronic hepatitis C and chronic hepatitis B. MATERIALS AND METHODS 110 consecutive patients with chronic liver disease admitted to the Gastroenterology Department, Government Medical College, Kozhikode were selected for the study. The categories of chronic liver disease included in our study were alcoholic cirrhosis (Group I, n = 40, cryptogenic cirrhosis (Group II, n = 30, chronic hepatitis C (Group III, n = 20 and chronic hepatitis B (Group IV, n = 20. Serum iron, ferritin, total iron binding capacity and transferrin saturation were estimated in the fasting sample. Statistical Analysis- Analysis was performed using nonparametric Kruskal-Wallis and Bonferroni test to assess statistical significance of difference of continuous variables among and between groups, respectively. The results were considered statistically significant at the level of p <0.05. RESULTS The serum iron level was normal and total iron binding capacity was low in all the four groups of chronic liver disease. Serum ferritin and transferrin saturation were significantly higher in alcoholic cirrhosis in comparison with cryptogenic cirrhosis and chronic hepatitis B, but was not statistically significant in comparison with chronic hepatitis C. CONCLUSION We observed irregularities in iron status in patients with alcoholic cirrhosis, cryptogenic cirrhosis, chronic hepatitis C and chronic hepatitis B.

    Of the estimated 50 million new cases of hepatitis B virus (HBV) infection diagnosed annually, 5-10% of adults and up to 90% of infants will become chronically infected, 75% of these in Asia where hepatitis B is the leading cause of chronic hepatitis, cirrhosis and hepatocellular carcinoma (HCC). In Indonesia, 4.6% of the population was positive for HBsAg in 1994 and of these, 21% were positive for HBeAg and 73% for anti-HBe; 44% and 45% of Indonesian patients with cirrhosis and HCC, respectively, were HBsAg positive. In the Philippines, there appear to be two types of age-specific HBsAg prevalence, suggesting different modes of transmission. In Thailand, 8-10% of males and 6-8% of females are HBsAg positive, with HBsAg also found in 30% of patients with cirrhosis and 50-75% of those with HCC. In Taiwan, 75-80% of patients with chronic liver disease are HBsAg positive, and HBsAg is found in 34% and 72% of patients with cirrhosis and HCC, respectively. In China, 73% of patients with chronic hepatitis and 78% and 71% of those with cirrhosis and HCC, respectively, are HBsAg positive. In Singapore, the prevalence of HBsAg has dropped since the introduction of HBV vaccination and the HBsAg seroprevalence of unvaccinated individuals over 5 years of age is 4.5%. In Malaysia, 5.24% of healthy volunteers, with a mean age of 34 years, were positive for HBsAg in 1997. In the highly endemic countries in Asia, the majority of infections are contracted postnatally or perinatally. Three phases of chronic HBV infection are recognized: phase 1 patients are HBeAg positive with high levels of virus in the serum and minimal hepatic inflammation; phase 2 patients have intermittent or continuous hepatitis of varying degrees of severity; phase 3 is the inactive phase during which viral concentrations are low and there is minimal inflammatory activity in the liver. In general, patients who clear HBeAg have a better prognosis than patients who remain HBeAg-positive for prolonged periods of

    Full Text Available Despite of extensive blood product screening and national immunization programs, chronic hepatitis B and C infections continues to be a global problem with high mortality, morbidity and economic impact. Even though acquisition of these infections mostly occurs in childhood, major problems appear in adulthood. Cirrhosis and HCC are two major expected late events related to chronic hepatitis B and C infections. Rarely, children may also face these complications. To avoid these complications and increase the life expectancy in adults treatment of these two type infections should be started in childhood with appropriate patient selection. In contrast to children, adults are luckier in terms of treatment alternatives. They have the chance to use more potent antivirals with higher genetic barrier and pegylated form of interferons. Recently, the use of pegylated interferon and ribavirin combinations has been approved in children in Chronic HCV infection. However, chronic hepatitis B treatment in children is still dependent on the use of one type antiviral drug and conventional interferon. Treatment in early ages with an antiviral agent that has limited genetic barrier may block the chance of treatment or reduce the response rate in adulthood in chronic hepatitis B infection. This burden indicates the necessity of new therapeutic modalities in children. In this term pegylated interferons may be one of the optiones. In this article we aimed to reviewe the efficacy and safety of conventional and pegylated interferons, for the treatment of Hepatitis C and B infections in children.

    Tracer quantities of colloidal 198 Au were used to estimate the hepatic blood flow in normal children and in children with active or progressive chronic hepatitis and also to obtain scintigrams of the liver. In active chronic hepatitis a significant decrease in HBF values was observed, suggesting that the method may be used as a diagnostic criterion which is superior to hepatic scintigraphy. In progressive chronic hepatitis HBF values even lower than those in active hepatitis were observed. Together with more characteristic clinical findings and abnormal results of biochemical function tests, they underline the value of the method in estimating the severity and the evolution of the disease.

    The immunological result of infection with Hepatitis C virus (HCV) depends on the delicate balance between a vigorous immune response that may clear the infection, but with a risk of unspecific inflammation and, or a less inflammatory response that leads to chronic infection. In general, exhaustion...... and impairment of cytotoxic function of HCV-specific T cells and NK cells are found in patients with chronic HCV infection. In contrast, an increase in immune regulatory functions is found primarily in form of increased IL-10 production possibly due to increased level and function of anti-inflammatory Tregs...

    The impact of chronic hepatitis B on the clinical outcome of acute hepatitis A remains controversial. The aim of present study was to evaluate the clinical characteristics of acute hepatitis A in cases with underlying chronic hepatitis B compared to cases of acute hepatitis A alone. Data on 758 patients with acute hepatitis A admitted at two university-affiliated hospitals were reviewed. Patients were classified into three groups: group A, patients with both acute hepatitis A and underlying chronic hepatitis B (n = 27); group B, patients infected by acute hepatitis A alone whose sexes and ages were matched with patients in group A (n  = 54); and group C, patients with acute hepatitis A alone (n = 731). None of the demographic features of group A were significantly different from those of group B or C, except for the proportion of males and body weight, which differed from group C. When comparing to group B, clinical symptoms were more frequent, and higher total bilirubin and lower albumin levels were observed in group A. When comparing to group C, the albumin levels were lower in group A. There were no differences in the duration of hospital stay, occurrence of acute kidney injury, acute liver failure, prolonged cholestasis, or relapsing hepatitis. This study revealed that clinical symptoms and laboratory findings were less favorable for patients with acute hepatitis A and chronic hepatitis B compared to those with acute hepatitis A alone. However, there were no differences in fatal outcomes or serious complications. Copyright © 2012 Wiley Periodicals, Inc.

    1993-01-01

    Hepatitis C virus (HCV) has been shown to induce anti-liver-kidney microsomal-1 (LKM1) antibody positive chronic active hepatitis, simulating type 2 autoimmune chronic active hepatitis. The cases of five patients presenting with features of type 1 (antinuclear antibody positive) autoimmune chronic active hepatitis and extrahepatic autoimmune manifestations, in whom immunosuppressive treatment had no effect on liver disease are presented. In these patients, HCV infection could be shown by the presence in serum of anti-HCV antibodies and HCV-RNA detected by polymerase chain reaction. These cases suggest the following: (a) chronic HCV infection can mimic type 1, as well as type 2, autoimmune chronic active hepatitis; (b) HCV infection might be systematically sought in patients presenting with features of type 1 autoimmune chronic active hepatitis, with special care in patients who are unresponsive to immunosuppressive treatment.

    Hepatitis A is among the diseases that can be prevented with vaccination in our time. Acute hepatitis A progresses more severely in individuals with a liver disease. Therefore, patients with a chronic liver disease (because of hepatitis B or hepatitis C) are advised vaccination with the hepatitis A vaccine. This study is aimed to determine the seroprevalence of hepatitis A virus (HAV) antibodies in patients infected with hepatitis C virus or hepatitis B virus in Konya province of Turkey. A total of 537 patients who had chronic viral hepatitis between January 2011 and December 2014 were included in the study. Serum samples were collected from each patient and tested for anti-HAV using the chemiluminescent microparticle immunoassay. The overall seroprevalence of total anti-HAV IgG was 94.2%. The overall prevalence of anti-HAV IgG in patients with chronic hepatitis B virus and hepatitis C virus infection was 97.5 and 93.6%, respectively. Anti-HAV IgG positivity was 97.4% in cirrhotic patients and 93.9% in noncirrhotic individuals. At the end of the study, being older than 40 years and living in a rural area were found to be independent risk factors for anti-HAV IgG seropositivity. In conclusion, we recommend that patients younger than 40 years and/or those living in cities and having a chronic liver disease should be vaccinated with the hepatitis A vaccine.

    2014-05-12

    We report here a case of recurrent paratyphoid fever A with hepatitis A co-infection in a patient with chronic hepatitis B. A 26-year-old male patient, who was a hepatitis B virus carrier, was co-infected with Salmonella enterica serovar Paratyphi A and hepatitis A virus. The recurrence of the paratyphoid fever may be ascribed to the coexistence of hepatitis B, a course of ceftriaxone plus levofloxacin that was too short and the insensitivity of paratyphoid fever A to levofloxacin. We find that an adequate course and dose of ceftriaxone is a better strategy for treating paratyphoid fever. Furthermore, the co-infection of paratyphoid fever with hepatitis A may stimulate cellular immunity and break immunotolerance. Thus, the administration of the anti-viral agent entecavir may greatly improve the prognosis of this patient with chronic hepatitis B, and the episodes of paratyphoid fever and hepatitis A infection prompt the use of timely antiviral therapy.

    To evaluate the usefulness of screening liver ultrasonography (US) for hepatocellular carcinoma (HCC) detection in patients with chronic hepatitis or hepatic cirrhosis caused by hepatitis B virus (HBV). A retrospective study was performed with 1,189 patients with clinical hepatopathy caused by HBV who underwent screening liver US for HCC detection at least twice. All patients were followed up with liver US examinations (mean, 8.3 times), CT, or MR for at least 3 months (range, 3-102 months; mean, 47 months) for the detection of HCC. The study population was divided into two groups: chronic hepatitis (n=492) and hepatic cirrhosis (n=697), which was further divided into two groups with (n=156) or without (n=541) evident shrinkage. The radiologic examinations that had detected HCC for the first time were analyzed and compared between the groups. Among 20 (4.1%) patients with chronic hepatitis and 132 (18.9%) patients with hepatic cirrhosis diagnosed as HCC, screening US was the modality of detection in 17 (85.0%) of 20 patients with chronic hepatitis and 76 (57.6%) of 132 patients with hepatic cirrhosis (p=0.038, Chi-square test). The detection rate of HCC on screening US between the chronic hepatitis and hepatic cirrhosis with evident shrinkage (51.4%, 19/37) showed a significant difference (p=0.027, Chi-square test). For chronic liver disease caused by HBV, screening US for HCC detection is more useful in patients with chronic hepatitis than with hepatic cirrhosis with evident shrinkage

    Assessment of hepatic fibrosis is important for determining prognosis, guiding management decisions, and monitoring disease. Histological evaluation of liver biopsy specimens is currently considered the reference test for staging hepatic fibrosis. Since liver biopsy carries a small but significant risk, noninvasive tests to assess hepatic fibrosis are desirable. This editorial gives an overview on noninvasive methods currently available to determine hepatic fibrosis and their diagnostic accur...

    The purpose of the given research work was to study the features of morphologic changes arising for treatment of chronic hepatitis with Neoselen. It was established a picture of chronic active hepatitis in the liver of rats with the following development of chronic persisting hepatitis by the 40 daily administration of heliotrine and its transmission into cirrhosis in a certain part of animals. Hepatic cirrhosis has a small nodal portal character by its pathognomonic morphologic signs. A noticeable remittance of destructive necrotic changes in hepatic parenchymatous elements and reduction in a volume of proliferative inflammatory infiltration with an acceleration in process of its fibrozation in only periportal zones of hepatic lobules found to be for treatment of chronic hepatitis with Neoselen. That prevents from transmission of chronic hepatitis into cirrhosis in a greater part of animals that is a morphologic evidence of importance of selenium in a restorative process of biologic membranes and its involvement in a remittance process of destructive and inflammatory changes in the liver and prevention from development of agressive hepatitis and its transmission into cirrhosis.

  18. Hemostatic System in Chronic Viral Hepatitis

    Directory of Open Access Journals (Sweden)

    Natalia Borisova

    2018-06-01

    Full Text Available Hemostasis is balanced by pro- and anticoagulant and pro- and antifibrinolytic factors, most of these being synthesized by the liver. Advanced liver disease is associated with perturbations in the level of these factors due to secretory deficiencies. Thrombocytopenia, reduced levels of factor II-VII-X, and anti-fibrinolytic factors are all features of CHC infection, suggesting hypocoagulability. However, higher concentrations of VWF and factor VIII, as well as lower concentrations of anticoagulant factors including protein C and S, have also been reported in CHC infections, suggesting hypercoagulability. Thus, the hemostatic balance in the patient with liver disease is relatively unstable as evidenced by the occurrence of both bleeding and thrombotic complications in a significant proportion of patients with chronic viral hepatitis. In patients with chronic liver disease (CLD, in whom extremely complex alterations of hemostasis occur, one cannot rely on levels of individual coagulation factors, or on simplified tests of hemostasis such as the PT or APTT to predict the hemostatic status. To determine the hemostatic status in these patients, more complex tests and a more comprehensive overview of the hemostatic changes are required. In connection with the latest studies, a revision of the methods for correction of hemostatic system disorders in patients with acute and chronic liver diseases becomes urgent.

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

    The chronic aggressive hepatitis, type II b, is attended by an elevation of the plasma and blood viscosity values, which corresponds to the degree of the mesenchymal and parenchymatous inflammation. This elevation is mainly due to a pathological increase of those immunglobuline fractions which are effective on the viscosity. During the application of a fluocortolon monotherapy, there could be noticed a regression as well as a normalisation of the primarily pathological laboratory parameters, being typical for an aggressive hepatitis. These changes were correlated to a decrease of the blood and plasma viscosity. The improved blood flow property is considered to be caused by the decrease of the IgG-fraction. The significance of an improved blood flow property will be discussed in correlation to the effect of the microcirculation, resulting in a better nutrition of the cell with the necessary nutritive substances, as well as on the regression of the inflammatory parameters hereby provoked. In addition to the possible benefits of the introduced cortison therapy will be considered in this context.

    Full Text Available Chronic obstructive pulmonary disease (COPD is a preventable, treatable disease with significant extrapulmonary manifestations that could affect negatively its course in some patients. Hepatitis C virus infection (HCV, on the other hand, is associated with a number of extrahepatic manifestations. COPD patients have increased prevalence of HCV and patients with HCV, especially older ones, have increased prevalence and faster progression of COPD. HCV infection exerts long-term effects on lung tissue and is an additional risk factor for the development of COPD. The presence of HCV is associated with an accelerated loss of lung function in COPD patients, especially in current smokers. COPD could represent extrahepatic manifestation associated with HCV infection. The aim of this article was to review the literature on prevalence of HCV in COPD and vice versa, pathogenetic link and the consequences of their mutual existence.

  2. Extrahepatic manifestations associated with Chronic Hepatitis C Virus Infection

    Directory of Open Access Journals (Sweden)

    A. Flores-Chávez

    Full Text Available Summary Chronic hepatitis C virus (HCV infection has been associated with both organ-specific and systemic autoimmune diseases, with cryoglobulinemia being the most frequent associated disease. Experimental, virologic, and clinical evidence have demon-strated a close association between HCV infection and some systemic autoimmune diseases, especially Sjögren’s syndrome, but also rheumatoid arthritis and lupus. A higher prevalence of hematological processes has also been described in patients with HCV infection, including cytopenias and lymphoproliferative disorders (B-cell lymphoma. In addition, patients with chronic HCV infection have a higher frequency of other extrahepatic manifestations including endocrine, metabolic and cardiovascular disorders that may worse the prognosis of patients, along with neuropsychiatric manifestations and general symptoms that have a significant influence on the quality of life of the patient. Direct-acting antiviral therapies (DAAs that have recently begun to be used are providing the opportunity to effectively cure chronic HCV infection and reduce the burden of both hepatic and extrahepatic complications.

    2017-07-01

    Current treatment with oral nucleos(t)ides entecavir or tenofovir provide sustained suppression of HBV replication and clinical benefit in most chronic hepatitis B virus (HBV) infected persons. However, HBV rebound generally occurs upon drug discontinuation due to persistence of genomic HBV reservoirs as episomic cccDNA and chromosomic integrated HBV-DNA. There is renewed enthusiasm on HBV drug discovery following recent successes with antivirals for hepatitis C and immunotherapies for some cancers. Areas covered: New drugs that target distinct steps of the HBV life cycle are been developed, including inhibitors of viral entry, new polymerase inhibitors, capsid and assembly inhibitors, virus release blockers, and disruptors of cccDNA formation and transcription. Alongside these antivirals, agents that enhance anti-HBV specific immune responses are being tested, including TLR agonists, checkpoint inhibitors and therapeutic vaccines. Expert opinion: The achievement of a 'functional cure' for chronic HBV infection, with sustained HBsAg clearance and undetectable viremia once medications are stopped, represents the next step in the pace towards HBV elimination. Hopefully, the combination of new drugs that eliminate or functionally inactivate the genomic HBV reservoirs (cccDNA and integrated HBV-DNA) along with agents that enhance or activate immune responses against HBV will lead to a 'definitive cure' for chronic HBV infection.

    2012-02-01

    The aim of investigation was to study the frequency of IR in type of viral hepatitis C, correlation with the degree of hepatic lesion and liver cirrhosis. 130 patients were investigated: 20 with acute hepatitis C; 38 with chronic hepatitis C; 72 with cirrhosis: among them 10 with Stage A, 14 with Stage B and 48 with Stage C. Also we used 30 healthy people as the controls. The study demonstrates significant changes of insulin, glucose, HOMA-IR type of viral hepatitis C, correlation with the degree of hepatic lesion and liver cirrhosis. In patients with liver cirrhosis levels of HOMA-IR is higher than in patients with chronic hepatitis C. In patients with acute hepatitis C levels of HOMA-IR was normal as in the control group. The results showed that various types of chronic viral hepatitis C and stages of cirrhosis set to increase HOMA-IR versus the controls., which were the most prominent in cases of severe hepatic lesion, which indicates that insulin resistance is a frequent companion of CHC.

    To quantitatively assess steatosis by a morphometric method and to study its relationship with other histological features of chronic hepatitis C (CHC). This was a comparative descriptive study. The study was carried out in the Department of Histopathology, Army Medical College, Rawalpindi, Pakistan, from March 2006 to March 2007. Patients who had undergone a liver biopsy for the evaluation of hepatitis C virus (HCV) infection were included in the study. Demographic characteristics and laboratory data were collected at the time of biopsy. The first hundred biopsy specimens that met the inclusion criteria were assessed for grades of steatosis (semiquantitatively), diameter of fat globules (by a morphometric method), necroinflammation, and fibrosis (semiquantitatively). Liver biopsies were processed for paraffin embedding, stained with hematoxylin and eosin, whereas Gomori's Reticulin stain was used for the evaluation of fibrosis. Out of 46 cases showing fatty change, pansteatosis was observed in 24 (52%) patients: 12 (26%) cases had a pericentral and mid zonal distribution of fat globules and eight (17.5%) cases revealed a mid zonal pattern only. There were two (4.5%) cases in which fat globules were found in periportal and mid zonal areas. None of the histological parameters (the stage of fibrosis and grades of inflammation) had any significant correlation with these distribution patterns of steatosis. The diameter of fat droplets was quantified by morphometry. A mixed pattern of steatosis was observed more frequently (21 out of 46 cases): 17 cases had microglobules and eight biopsies showed macroglobules. The size of the fat globules exhibited a significant correlation with the stage of fibrosis ( P < 0.0001). The analysis of the grades of necroinflammation did not reveal any significant relationship with the diameter of fat globules. A mixed pattern of fat globules is more frequently observed in CHC, but macrovesicular steatosis is associated with a higher stage

    Hepatitis A and B vaccines are effective in preventing superinfection and sequelae in patients with chronic hepatitis B or C. We describe immunity and vaccination against hepatitis A and B in chronic hepatitis patients from the US Chronic Hepatitis Cohort Study. We identified chronic hepatitis B and C patients with healthcare utilization during 2006-2008 and 12 months of enrollment. We used electronic laboratory records to determine immunity and medical and billing records for vaccination history. Immunity against hepatitis A was defined by positive hepatitis A antibody or documented vaccination. Immunity against hepatitis B was defined as hepatitis B surface antibody level ≥10 mIU/mL or core antibody positive, or by documented vaccination. Among 1635 chronic hepatitis B patients, 978 (59.8%) were immune or vaccinated against hepatitis A, 122 (7.5%) had negative hepatitis A antibody tests, and 535 (32.7%) had no testing or vaccination record. Among 5328 chronic hepatitis C patients, 2998 (56.3%) were immune or vaccinated against hepatitis A, 659 (12.4%) had negative hepatitis A antibody tests, and 1671 (31.4%) had no testing or vaccination record. Additionally, 3150 (59.1%) chronic hepatitis C patients were immune or vaccinated against hepatitis B, 1003 (18.8%) had a negative test result, and 1175 (22.1%) were neither tested for nor vaccinated against hepatitis B. Approximately 40% of chronic hepatitis B and C patients are susceptible to or have no documented immunity or vaccination against hepatitis A or hepatitis B. Clinicians should consider antibody testing and vaccination for this vulnerable population. © The Author 2014.

    In 1997, in Japan, a non-enveloped single stranded circular DNA virus was recovered from a patient. Who developed post transfusion hepatitis not related to any of the know hepatitis viruses . The virus owes its name (T T) virus to the initials of the patient in whom the virus was first identified . Although this acronym might also stand for transfusion - transmitted virus, however, this name would emphasize only one, and certainly not the most frequent mode of this virus transmission. The taxonomy of the virus is uncertain but it is believed now that it may belong to a new family called paracircoviridae. TTDNA has been detected in liver, bone marrow, lung, spleen, pancreas, kidney, lymph nodes, skeletal muscles and thyroid gland as well as in saliva, tear, stool, bile, throat swabs, breast milk and semen while could not be detected in urine and sweat. TTV infection is transmitted parenterally by feco-oral or droplet routes, or sexual intercourse. These properties of virus influence its high prevalence in general population whether intrauterine transmission of virus is possible remains uncertain. The aim of this work is viewing the prevalence of TTV infection, mode of transmission, pathogenicity, diagnosis and management among chronic hepatitis B and C patients and control group

    Highlights: • PFOS chronic exposure induces sex-dependent hepatic steotosis in zebrafish. • PFOS interferes with β-oxidation, lipid synthesis, and lipid hepatic export process. • Zebrafish could be used as an alternative model for PFOS chronic toxicity screening. - Abstract: Perfluorooctane sulfonate (PFOS), one persistent organic pollutant, has been widely detected in the environment, wildlife and human. Currently few studies have documented the effects of chronic PFOS exposure on lipid metabolism, especially in aquatic organisms. The underlying mechanisms of hepatotoxicity induced by chronic PFOS exposure are still largely unknown. The present study defined the effects of chronic exposure to low level of PFOS on lipid metabolism using zebrafish as a model system. Our findings revealed a severe hepatic steatosis in the liver of males treated with 0.5 μM PFOS as evidenced by hepatosomatic index, histological assessment and liver lipid profiles. Quantitative PCR assay further indicated that PFOS significantly increase the transcriptional expression of nuclear receptors (nr1h3, rara, rxrgb, nr1l2) and the genes associated with fatty acid oxidation (acox1, acadm, cpt1a). In addition, chronic PFOS exposure significantly decreased liver ATP content and serum level of VLDL/LDL lipoprotein in males. Taken together, these findings suggest that chronic PFOS exposure induces hepatic steatosis in zebrafish via disturbing lipid biosynthesis, fatty acid β-oxidation and excretion of VLDL/LDL lipoprotein, and also demonstrate the validity of using zebrafish as an alternative model for PFOS chronic toxicity screening.

  1. Chronic hepatitis caused by persistent parvovirus B19 infection

    Directory of Open Access Journals (Sweden)

    2010-08-01

    Full Text Available Abstract Background Human infection with parvovirus B19 may lead to a diverse spectrum of clinical manifestations, including benign erythema infectiosum in children, transient aplastic crisis in patients with haemolytic anaemia, and congenital hydrops foetalis. These different diseases represent direct consequences of the ability of parvovirus B19 to target the erythroid cell lineage. However, accumulating evidence suggests that this virus can also infect other cell types resulting in diverse clinical manifestations, of which the pathogenesis remains to be fully elucidated. This has prompted important questions regarding the tropism of the virus and its possible involvement in a broad range of infectious and autoimmune medical conditions. Case Presentation Here, we present an unusual case of persistent parvovirus B19 infection as a cause of chronic hepatitis. This patient had persistent parvovirus B19 viraemia over a period of more than four years and displayed signs of chronic hepatitis evidenced by fluctuating elevated levels of ALAT and a liver biopsy demonstrating chronic hepatitis. Other known causes of hepatitis and liver damage were excluded. In addition, the patient was evaluated for immunodeficiency, since she had lymphopenia both prior to and following clearance of parvovirus B19 infection. Conclusions In this case report, we describe the current knowledge on the natural history and pathogenesis of parvovirus B19 infection, and discuss the existing evidence of parvovirus B19 as a cause of acute and chronic hepatitis. We suggest that parvovirus B19 was the direct cause of this patient's chronic hepatitis, and that she had an idiopathic lymphopenia, which may have predisposed her to persistent infection, rather than bone marrow depression secondary to infection. In addition, we propose that her liver involvement may have represented a viral reservoir. Finally, we suggest that clinicians should be aware of parvovirus B19 as an unusual

    We evaluated the clinical and virological characteristics of hepatitis A virus infection in persons concomitantly infected with hepatitis B virus (HBV) or hepatitis C virus (HCV). We enrolled 21 patients with acute hepatitis A and chronic hepatitis with no sign of liver cirrhosis, 13 patients who were positive for hepatitis B surface antigen (case B group), 8 patients who were anti-HCV positive (case C group), and 21 patients with acute hepatitis A without a preexisting liver disease (control A group). Two control groups of patients with chronic hepatitis B (control B group) or C (control C group) were also chosen. All control groups were pair-matched by age and sex with the corresponding case group. Fulminant hepatitis A was never observed, and hepatitis A had a severe course in 1 patient in the case B group and in 1 patient in the control A group. Both patients recovered. On admission, HBV DNA was detected in 1 patient in the case B group (7.7%) and in 13 patients (50%) in the control B group; HCV RNA was found in no patient in the case C group and in 16 patients (81.2%) in the control C group. Of 9 patients in the case B group who were followed up for 6 months, 3 became negative for hepatitis B surface antigen and positive for hepatitis B surface antibody, 2 remained positive for hepatitis B surface antigen and negative for HBV DNA, and 4 became positive for HBV DNA with a low viral load [corrected] Of 6 patients in the case C group who were followed up for 6 months, 3 remained negative for HCV RNA, and 3 had persistently low viral loads. Concomitant hepatitis A was always self-limited, associated with a marked inhibition of HBV and HCV genomes, and possibly had a good prognosis for the underlying chronic hepatitis.

    A retrospective study over 26 female patients with chronic active hepatitis was made. The mean age was 39 years old, the mean length of illness of 8 months; 5 patients had positive markers for hepatitis B. Patients were selected with the grade of histological activity: 8 patients had a mild form from disease (2A) and 16 with a severe one (2B). The predominant group was 2B. Severe inflammatory infiltration was the hallmark and multiobulillar necrosis, bridging, eosinophils and hiperplasia of kuppfer cells were found only in this group. Clinical features range from hepatic manifestations to systemic ones. Chronic active hepatitis may present with cholestasis, but the latter is not always related with the grade of activity. Group 2B had elevated aminotransferases and a low concentration for protrobine.

    BACKGROUND: Millions of people worldwide suffer from hepatitis C, which can lead to severe liver disease, liver cancer, and death. Direct-acting antivirals (DAAs), e.g. sofosbuvir, are relatively new and expensive interventions for chronic hepatitis C, and preliminary results suggest that DAAs may...... eradicate hepatitis C virus (HCV) from the blood (sustained virological response). Sustained virological response (SVR) is used by investigators and regulatory agencies as a surrogate outcome for morbidity and mortality, based solely on observational evidence. However, there have been no randomised trials...... hepatitis C-related morbidity, serious adverse events, and health-related quality of life. Our secondary outcomes were all-cause mortality, ascites, variceal bleeding, hepato-renal syndrome, hepatic encephalopathy, hepatocellular carcinoma, non-serious adverse events (each reported separately), and SVR.

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

    1989-01-01

    A high serum cortisol concentration, apparently due to increased cortisol-binding globulin (CBG), was found in a patient (index case) with chronic active hepatitis (CAH). We therefore performed further studies to determine whether increased cortisol binding is generally associated with CAH. Serum samples were obtained from 15 hospitalized patients with long-term liver function test elevations but no evidence of cirrhosis, 15 normal subjects without a history of hepatitis, four healthy pregnant women, and 10 alcoholic patients with stigmata of cirrhosis. Serum cortisol binding was measured by an adaptation of a previously described charcoal uptake method. Thyroxine-binding globulin (TBG) and sex hormone-binding globulin were determined by radioimmunoassays. Charcoal uptake of 125I cortisol from sera of normal subjects and additional patients with CAH revealed that increased serum cortisol binding by a saturable site, presumably CBG, was associated with CAH. Cortisol binding was significantly correlated with immunoassayable TBG, suggesting that in CAH, similar mechanisms may be responsible for increasing the serum concentrations of CBG and TBG

    Full Text Available ObjectiveTo study the quality of life (QoL and its influential factors among outpatients with chronic hepatitis B or C. MethodsPatients diagnosed with chronic hepatitis B or C between March 2012 and March 2014 were included in the hepatitis group, whereas volunteers presenting with neither significant physical nor mental diseases, who accompanied visiting patients or underwent physical examination, were involved in the control group. A survey using the Short Form-36 (SF-36 Chinese version, the Chronic Liver Disease Questionnaire (CLDQ, and the Social Support Rating Scale (SSRS were performed within the above groups. ResultsThe SF-36 scores of the hepatitis group were significantly lower than those of the control group in physical role, general health, vitality, social functioning, emotional role, and mental health (P<0.05. The CLDQ scores of the hepatitis group were significantly lower than those of the control group in systemic symptoms, role emotion, and anxiety (P<0.05. The hepatitis patients displayed significantly lower scores in all four scales of SSRS (P<0.05. Multivariable linear regression analysis showed that age, sex, occupation, marital status, income, subjective support, and social support utilization significantly influenced the QoL among hepatitis patients. ConclusionThe QoL of outpatients with chronic hepatitis B or C is poor. The QoL of patients showing the characteristics of old age, female sex, divorce, farmer, lower income, less subjective support, and poor social support utilization require more attention to their QoL. Medical workers should provide proper individualized health guidance for those patients.

    To determine the molecular epidemiology of Hepatitis C virus (HCV) in K.S.A. 492 histological proven chronic HCV patients recruited from all regions of KSA,between November 1999 and March 2002 were genotyped and subtyped using amplified products of specific primers from the 5-UTR region in a reverse transcription polymerase chain reaction followed by a hybridization technique. 62% of Saudis were found to be genotype4. Other genotypes were 1(24.1%); 2(7.4%); 3(5.9%); 5(0.3%) add 10(0.3%).All regions showed similar distribution except except the Eastern region where subtype 2a/c emerged. 86% of Saudi chronic hepatitis C cases are due to genotypes 1 and 4.Since these are considered difficult to treat an aggressive approach to management using combination therapy of pegylated interferon plus ribavirin for 48 weeks should be considered for all cases of chronic hepatitis C until genotyping proves otherwise.

  15. Chronic hepatitis C and fibrosis: evidences for possible estrogen benefits

    Directory of Open Access Journals (Sweden)

    Liana Codes

    Full Text Available The main injury caused by hepatitis C virus is the hepatic fibrosis, as a result of a chronic inflammatory process in the liver characterized by the deposit of components from the extracellular matrix. The fibrosis development leads to the modification of the hepatic architecture, of the hepatocellular function and to irregularities in the microcirculation. The tissue remodeling process observed in fibrosis has stellate cells, located at the space of Disse, as main acting agents. These cells, in response to a harmful stimulus, undergo phenotypic changes from non-proliferating cells to proliferating cells that express a- smooth-muscle actin (a-SMA, a process called as transdifferentiation. There are evidences that the oxidative stress is involved in the chronic liver disease and serves as bond between the injury and the hepatic fibrosis. A number of studies suggest that the estrogen, at physiological levels, presents an antifibrogenic action probably through an antioxidant effect, decreasing the levels of lipid peroxidation products in the liver and blood, thus inhibiting the myofibroblastic transformation of stellate cells and contributing for gender-associated differences in relation to the fibrosis development. The aim of this paper was to describe data from literature concerning the interaction between chronic hepatitis C and estrogens, pregnancy, use of oral contraceptives, menopause and hormone reposition therapy.

    To assess the role of altered hepatic folate metabolism in the pathogenesis of the folate deficiency of chronic alcoholism, the hepatic metabolism of a tracer dose of 3 H-PteGlu was compared in monkeys given 50% of energy as ethanol for 2 years and in control monkeys. Long-term ethanol feeding resulted in mild hepatic injury, with a significant decrease in hepatic folate levels. Chromatographic studies of liver biopsies obtained after the tracer dose indicated that the processes of reduction, methylation, and formylation of reduced folate and the synthesis of polyglutamyl folates were not affected by long-term ethanol feeding. Hepatic tritium levels were significantly decreased in the ethanol-fed group. These studies suggest that the decrease in hepatic folate levels observed after long-term ethanol ingestion is due to a decrease in hepatic folate levels observed after long-term ethanol ingestion is due to a decreased ability to retain folates in the liver, whereas reduction and further metabolism of folates is not affected

    2013-01-01

    Full Text Available Chronic hepatitis C is a major public health problem and its burden is expected to increase in the near future. Out of six genotypes of hepatitis C virus (HCV identified, genotype 1 is the most prevalent genotype in America and Europe. With peg-interferon alpha and ribavirin dual therapy, sustained virological response (SVR is achieved in less than half of the patients infected with HCV genotype 1. Moreover, this dual therapy also causes many intolerable adverse effects. Telaprevir is an HCV protease inhibitor approved for chronic hepatitis C genotype 1 mono-infection. It is a type of direct acting antiviral drug acting through inhibition of viral non-structural 3/4A protease. It can be safely administered in mild hepatic dysfunction. Due to inhibition of CYP3A4 and P-glycoprotein, significant drug-drug interactions are possible with telaprevir. Trials have shown significantly higher SVR rates when telaprevir is added to peg-interferon alpha and ribavirin, particularly in patients with unfavorable prognostic factors. It is approved for use in treatment-naïve and previously treated patients. Rash and anemia are the major troublesome side-effects. Next-generation protease inhibitors may overcome the drawbacks of telaprevir and another approved HCV protease inhibitor - boceprevir. Evidence from small scale studies suggests that telaprevir may be used in conditions like HIV co-infection, post-transplantation and some HCV non-1 genotype infections also. Preliminary data show higher SVR rates with triple therapy even in patients with unfavorable interleukin-28B (IL28B genotype. With development of other direct acting antivirals, it might be possible to treat chronic hepatitis C with interferon-free regimens in future. This article briefly reviews the properties of telaprevir and its status in the context of rapidly evolving aspects of management of chronic hepatitis C.

    2008-12-06

    The revised Dutch College of General Practitioners' practice guideline 'Viral hepatitis and other liver diseases' offers advice in the diagnosis and management of viral hepatitis A, B and C and other liver diseases. The guideline is important for general practitioners as well as specialists in internal medicine and gastroenterology. The emphasis is on the management of chronic hepatitis B en C, because the prevalence of these diseases has increased in the Netherlands and, in addition, the treatment options for chronic hepatitis have improved. Consequently, timely recognition and adequate referral of patients with chronic hepatitis B or hepatitis C have become more important. However, many patients with a chronic liver disease have no symptoms. Therefore, the general practitioner should be aware that a patient visiting the practice with fatigue and malaise could have a liver disease if he or she belongs to a high-risk group or has had high-risk contacts. If the general practitioner repeatedly finds increased liver transaminase values during routine examination of asymptomatic patients, additional diagnostic tests should be performed. Further tests should focus on viral hepatitis as well as on non-alcoholic fatty liver disease and non-alcoholic steatohepatitis or, depending on the history-taking, liver damage due to excessive alcohol, medication or drug use.

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

    Full Text Available Objectives: Some of the patients with chronic hepatitis use both alternative product and/or antiviral treatment. These herbal products sometimes lead to clinical deterioration. In this study we aimed to determine the purpose of alternative product utilization and rate among the chronic hepatitis B (CHB and C (CHC patients. Methods: This prospective cohort study included 200 consecutive adult patients with chronic hepatitis B and C at the Department of Infectious Diseases, Ondokuz Mayis University, between 1 March 2012 and 30 July 2012. At enrollment, clinical information, demographics, laboratory variables and knowledge about alternative products were recorded. Results: Of the patients 150 had CHB, 50 had CHC. 54% of patients were male. Use of alternative products was 26%. Antiviral treatment rate was 48.5% for all patients. The most used alternative products were artichoke extract and honey. 67.3% of patients were using single alternative product whereas the others were using two or more alternative products. 46.2% of patients who use alternative product provided information about the alternative product usage, but the others did not. Conclusions: Majority of patients used alternative products. More than half of these patients did not give information to their physicians about their use of alternative medicine. Use of alternative product should be asked in all patients with chronic hepatitis. Herbal product usage was detected in majority of patients and also approximately half of these patients did not give information to their doctors about taking alternative medicine. In conclusion, it is necessary to take detailed information about herbal product usage in patients with chronic hepatitis. J Microbiol Infect Dis 2014; 4(3: 102-106

    It is known that hepatitis C virus (HCV) related to chronic liver disease may be associated with various immunological disorders, among these disorders are mixed cryoglobulinemia, serum antinuclear antibodies, antismooth muscle antibodies and liver/kidney microsomal antibody type 1 (LKM1). However, the actual prevalence and pathogenic role of these disorders in patients with chronic hepatitis C are unclear. It was our aim to estimate the prevalence of different autoimmune antibodies in cases of hepatitis C chronic liver disease and to assess if such changes have any clinical significance. A total of 30 chronic hepatitis C patients (22 males and 8 females) with a mean age of 43.5 +/- 6.7 years, all patients were ELISA II positive, HCV RNA PCR positive and HbsAg negative, with elevated ALT more than 2 folds of the normal, in addition to 20 healthy controls of matched age and sex were tested for rheumatoid factor, cryoglobulin, antinuclear antibody, antismooth muscle antibody, antimitochondrial antibody and LKM1. The rheumatoid factor was present in 18 (60%) of the HCV Ab +ve patients and in 1 (5%) of the controls (p 0.24), antinuclear antibody was positive in 4 (13.3%) of the patients and in 1 (5%) of the controls (p > 0.6), antismooth muscle antibody was positive in 1 (3.3%) of the patients and not detected in any of the controls, the antimitochondrial antibody and LKM1 were not detected in both the patients and the controls. In conclusion, we can see that chronic hepatitis C patients show prevalence of some autoimmune antibodies and their presence is not associated with any implication on the clinical presentation.

    Measurement of serum hepatitis B virus surface antigen (HBsAg) levels is important for the management of chronic hepatitis D patients in terms of monitoring response to antiviral therapy. This study aimed to evaluate the diagnostic performance of a new diagnostic kit, which quantitatively measures serum HBsAg level using an immunoradiometric assay (IRMA) based method. Measurements were compared with those obtained using a chemiluminescent microparticle immunoassay (CMIA) based method. The blood samples of 96 patients with chronic hepatitis B were used in this study. Copy numbers of serum hepatitis B virus (HBV) DNA were determined in 23 of these samples. The correlation between and the concordance of IRMA and CMIA results were determined using Pearson's correlation coefficients. P values of 0.05 were considered to be statistically significant throughout. Laboratory diagnoses based on CMIA. Furthermors, serum HBsAg levels by IRMA were found to be highly correlated with those determined by CMIA (correlation coefficient R 2= 0.838, P 2= 0.067, P=0.316 by IRMA, and R 2= 0.101, P=0.215 by CMIA). The diagnostic performance of the investigated IRMA method of determining HBsAg levels was found to be comparable with that of a CMIA based method in chronic hepatitis B patients

    To analyze adipokine concentrations, insulin resistance and hepatic expression of suppressor of cytokine signaling 3 (SOCS-3) in patients with chronic hepatitis C genotype 1 with normal body weight, glucose and lipid profile. The study group consisted of 31 patients with chronic hepatitis C and 9 healthy subjects. Total levels of adiponectin, leptin, resistin, visfatin, omentin, osteopontin and insulin were measured using an ELISA kit. The hepatic expression of SOCS-3 was determined by the use of the reverse transcription polymerase chain reaction method. Homeostasis model assessment for insulin resistance (HOMA-IR) values were significantly higher in hepatitis C virus (HCV) infected patients without metabolic disorders compared to healthy controls (2.24 vs 0.59, P = 0.0003). Hepatic steatosis was observed in 32.2% of patients with HCV infection and was found in patients with increased HOMA-IR index (2.81 vs 1.99, P = 0.05) and reduced adiponectin level (5.96 vs 8.37, P = 0.04). Inflammatory activity (G ≥ 2) was related to increased osteopontin concentration (34.04 vs 23.35, P = 0.03). Advanced liver fibrosis (S ≥ 2) was associated with increased levels of omentin and osteopontin (436.94 vs 360.09, P = 0.03 and 32.84 vs 20.29, P = 0.03) and reduced resistin concentration (1.40 vs 1.74, P = 0.047). No correlations were reported between adipokine profile, HOMA-IR values and hepatic expression of the SOCS-3 gene. We speculated that no relationship between adipokines and HOMA-IR values may indicate that HCV can induce insulin resistance itself. Some adipokines appear to be biochemical markers of steatosis, inflammation and fibrosis in patients with chronic HCV infection. © 2014 Baishideng Publishing Group Inc. All rights reserved.

    The therapeutic experience of interferon-alpha therapy against hepatitis D virus infection in affected children is rather limited. For this reason, we conducted a retrospective study (duration: 1991-1995) in order to evaluate the efficacy and the safety of interferon-alpha in children suffering from chronic hepatitis D in Northwestern Greece. Seven children who were found to be infected with HDV in a total of 324 children seropositive for hepatitis B virus infection during the 5-year period of the study were treated with interferon-alpha, 3 x 10(6) U/m2 body surface area, intramuscularly or subcutaneously, 3 times weekly for 1 year (after an informed consent obtained from their parents). Patients were assessed monthly by hematological serological and biochemical tests. Clinical progress, levels of serum alanine aminotransferase, hepatitis D ribonucleic acid (HDV-RNA) and hepatitis B deoxyribonucleic acid (HBV-DNA), seroconversion of hepatitis B surface antigen (HBsAg) and Hepatitis Be Antigen (HBeAg) and liver histology were used as response criteria. Posttreatment alanine transferase levels were significantly reduced (P < 0.05) but Immunoglobulin M and total anti-hepatitis D virus (anti-HDV) antibodies remained positive in all, while hepatitis D ribonucleic acid persisted positive in 4 cases. In addition, no seroconversion of HBsAg or HBeAg was noted and the liver histology progress was disappointing. Side effects including mild fever, arthralgias and malaise and reversible neutropenia and thrombocytopenia were common, but not particularly disturbing. Nevertheless, the children remained fully active on treatment, felt well and attended school. Initially 4 children had been below the 10th percentile for weight and height. All thrived during treatment and two crossed above the 10th percentile indicating height velocity and body mass index increase. The administration of regular interferon-alpha doses for treating children with chronic hepatitis D was safe as

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

    Hepatitis B virus (HBV) may reactivate when treating chronic hepatitis C (CHC) with direct acting antivirals (DAA). We aim to investigate the risk of HBV reactivation during DAA therapy. Chronic hepatitis C patients receiving pan-oral DAA therapy from December 2013 to August 2016 were evaluated. Fifty-seven patients that had a past HBV infection (negative hepatitis B surface antigen [HBsAg] and positive hepatitis B core antibody) and seven patients that had a current HBV infection (positive HBsAg) were enrolled. Serum HBV and hepatitis C virus (HCV) markers were regularly measured. The endpoints were the HCV sustained virological response (SVR) and the HBV virological/clinical reactivation. The overall SVR 12 rate was 96.9%, and two patients, one with positive HBsAg, had a relapse of HCV. No episodes of HBV virological reactivation were observed among the patients with a past HBV infection. For the seven patients with a current HBV infection, HBV virological reactivation was found in four (57.1%) of the seven patients. Clinical reactivation of HBV was observed in one patient with pretreatment detectable HBV DNA and recovered after entecavir administration. For the other three patients with HBV virological reactivation, the reappearance of low level HBV DNA without clinical reactivation was observed. HBsAg levels demonstrated only small fluctuations in all the patients. There was a minimal impact of hepatitis B core antibody seropositivity on HCV efficacy and safety. For CHC patients with current HBV infection, the risk of HBV reactivation was present, and monitoring the HBV DNA level during therapy is warranted. © 2017 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

    Full Text Available Joint syndrome evolution was prospectively followed up in a 49-year-old woman who had serum hepatitis in 1990. When she came to a rheumatologist for the first time in 1999 she complained of occasional joint pain. She did not have joint inflammatory changes at that time but chronic hepatitis С was revealed at the examination. Hepatitis С diagnosis was confirmed by morphological and repeated virological evaluations. During antiviral treatment the pt developed symmetrical polyarthritis involving hand joints. Elevation of cryoglobuline, rheumatoid factor and antinuclear antibodies level was revealed. During the next year polyarthritis recurred and later acquired undulatory course with periods of exacerbation and stabilization. Attempts of treatment with sulfasalazine failed due to transaminase elevation. In 2006 ulnar deviation appeared and rheumatoid factor level remained elevated. MRI showed multiple erosions of carpal bones. Considering features of joint syndrome development joint damage in this pt was regarded as arthritis associated with chronic hepatitis C.

    There have been limited studies investigating the impact of chronic hepatitis B virus infection on the growth of children. Our objective was to investigate the prevalence of malnutrition in children with chronic hepatitis B infection. The nutritional status of patients was retrospectively evaluated in the outpatient Clinic of Pediatric Gastroenterology between February and November 2014. During the study, biochemical laboratory parameters, duration of disease, liver biopsy scores, and medication were evaluated. Additionally body mass index and body mass index centiles were calculated. Of the 96 patients in this study, 68 were male and 28 were female, and the mean age was 144.7±43.9 months and 146.1±47.3 months, respectively. According to body mass index centiles five (5.2%) patients were underweight, seven (7.3%) patients were overweight, and seven (7.3%) patients were obese. Moderate rates of malnutrition (including obesity) were found in chronic hepatitis B infection. Additional nutritional status information of healthy and sick children should be assessed in the infection's early period, and timely interventions should be initiated.

    Hepatitis B virus (HBV) is a member of Hepadnavirus family, which leads to chronic infection in around 5% of patients with a high risk of developing liver cirrhosis, liver failure, and hepatocellular carcinoma. 1 Despite the availability of prophylactic vaccines against hepatitis B for over 3 decades, there are still more than 2 billion people have been infected and 240 million of them were chronic. Antiviral therapies currently used in the treatment of CHB (chronic hepatitis B) infection include peg-interferon, standard α-interferon and nucleos/tide analogs (NAs), but none of them can provide sustained control of viral replication. As an alternative strategy, therapeutic vaccines for CHB patients have been widely studied and showed some promising efficacies in dozens of preclinical and clinical trials. In this article, we review current research progress in several types of therapeutic vaccines for CHB treatment, including protein-based vaccines, DNA-based vaccines, live vector-based vaccines, peptide-based vaccines and cell-based therapies. These researches may provide some clues for developing new treatments in CHB infection.

    Objective: To assess the effects of hepatitis B vaccination on the antibody titer in patients with chronic hepatitis C and to compare it with response in normal healthy subjects. Study Design: Interventional study. Place and Duration of Study: Shifa International Hospital, Islamabad, Pakistan, from January 2007 to January 2012. Methodology: Hepatitis vaccination (Heberbiovac-HB 20) was given intramuscularly to the patients of chronic hepatitis C (HCV group) and normal healthy subjects (control group) at 0, 1 and 6 months intervals. Anti-HBs titer was determined after second and third injection to assess the antibody response. Results: There were 46 patients in the HCV group and 45 patients in the control group. Mean age was 40.9 A +- 9.8 years in the HCV group and 33.18 A +- 8.35 years in the control group. Weight was 67.04 A +- 13.5 kg in the HCV group and 71.78 A +- 14.63 kg in the control group. Height was 162.45 A +- 9.06 cm in the HCV group and 167.03 A +- 7.83 cm in the control group. Anti-HBs antibody levels after the second injection were 253.89 A +- 76.76 mlU/mL in the HCV group and 245.81 A +- 72.65 mlU/mL in the control group (p=0.172). After third injection, the antibody levels were slightly higher in both groups. Conclusion: In patients with chronic hepatitis C and normal healthy subjects, Heberbiovac HB in standard dosage gave sero-protective levels in both groups and antibody titers were not significantly different in control and HCV group.

    Objective: To investigate the relationship between the ultrasonographic changes of gallbladder wall and the hepatic inflammation grading as well as fibrostic staging using ultrasound examination in patients with chronic viral hepatitis, and to survey the diagnostic standard for viral related cholecystitis. Methods: Five hundreds and nineteen chronic viral hepatitis patients and 104 normal control subjects were enrolled in the study. Ultrasound guided liver biopsy was performed in all patients with chronic viral hepatitis, in which the hepatic fibrostic stages(S) were divided into SI (n=148), S2(n=170), S3-4(n 201 ); and hepatic inflammation grades (G) were divided into G1 (n=124 ), G2 (n=204), G3 (n=191). The ultrasound scan was performed within 7 days after liver biopsy. The relationship between ultrasonographic changes of gallbladder and the hepatic inflammation grades and fibrostic stages were analyzed using statistic soft ware SPSS 11.5 for windows. Results: The percentage of the thickened gallbladder wall were 55%, 87%, 96% in S1, S2, S3-4, respectively, and were 45%, 82%, 95% in G1, G2, G3-4, respectively. Significant difference was revealed between G1 and G2, as well as between G2 and G3-4, with P < 0.05. Conclusion: A significant, positive correlative relationship exists between the ultrasonographic changes of gall-bladder wall and the hepatic inflammation grading and fibrostic staging in patients with chronic viral hepatitis.

    Full Text Available Chronic Hepatitis B virus (HBV infection is a major liver disease worldwide and its clinical manifestations are linked to immune response. The purpose of this study was to evaluate the relationship between selenium, copper, and zinc in comparison with transaminase level in chronic HBV patients. Serum samples of the HBV infected patients were obtained from Tooba medical center, Sari, Iran. Sixty patients were enrolled in this study (36 men and 24 women, mean age: 39.6 ± 12.2 years. The concentration of zinc, selenium, copper and transaminases were determined using an autoanalyzer system. Concentrations of selenium (0.273 ±0.056 μg/dl and zinc (2.1±0.037 was elevated in patients with low transaminase levels as were significantly different in comparison with patients with high transaminase level (P<0.05. Serum copper concentration was similar in two groups of patients. Elevated levels of transaminase concentrations were independently associated with low zinc and selenium concentrations in chronic HBV patients. It is concluded that serum zinc and selenium levels are associated with less hepatic damage in chronic HBV patients and might have a protective role during liver injury.

    OBJECTIVE: Liver biopsy is regarded as the gold standard for assessing disease activity in chronic hepatitis C, but sampling error is a potential limitation. Whether sampling variability applies equally to viral load assessment as it does to histology is uncertain. To examine this, we compared viral load between right- and left-lobe biopsy specimens from patients infected with hepatitis C virus (HCV). METHODS: Bilobe biopsies were taken from 16 patients who were serum positive for HCV RNA by reverse transcription-polymerase chain reaction. Genotype was identified by reverse line probe hybridization. There was an absence of competing risk factors for infectious and other liver diseases in this patient group. Histology and hepatic viral load were assessed blindly. None of the patients had received antiviral therapy at the time of study. RESULTS: Detection of HCV in right and left lobes was concordant with serum positivity in all cases. The viral load between lobes was highly correlated (p = 0.0003, r = 0.79). In contrast, the histological activity indices of inflammation and fibrosis\\/cirrhosis were poorly correlated between lobes (p = 0.038, r = 0.60, and p = 0.098, r = 0.50, respectively). CONCLUSION: Hepatic viral load variability does not suffer from the same degree of heterogeneity of sampling variability as does histology.

    Full Text Available Chronic hepatitis of viral etiology ranks very high in human pathology with respect to its socio-economic and medical significance. In viral hepatitis, membrane destruction occurs via the processes of lipoperoxidation, a valid factor that triggers the mechanism of hepatocyte necrosis. The glutathione system is also involved in the first line of cell defense actions against the effect of the free radicals. In this study, 128 patients with Chronic Hepatitis C (CHC were examined. The degree of antioxidant defense was determined by the indicators of the activity of the glutathione and glutathione-dependent enzymes. The total, reduced and oxidized glutathione levels were determined by V. G. Chernishov. The activity of the glutathione-dependent enzymes, viz., glutathione peroxidase (GP, glutathione reductase (GR and glutathione transferase (GT was measured by the method prescribed by S. N. Vlasova and co-authors (1990. The results of the investigations performed revealed that in CHC patients, deep-seated disorders were observed in the glutathione system manifested by a decrease in the total glutathione levels, its oxidized and reduced forms, changes in the glutathione enzymes and the interrelationships between the intensity of the changes and the degree of the intoxication syndrome.

    Full Text Available Chronic hepatitis B virus (HBV infection is a major global health problem with an estimated 400 million HBV carriers worldwide. In the natural history of chronic hepatitis B (CHB, spontaneous acute exacerbation (AE is not uncommon, with a cumulative incidence of 10%–30% every year. While exacerbations can be mild, some patients may develop hepatic decompensation and even die. The underlying pathogenesis is possibly related to the activation of cytotoxic T lymphocyte-mediated immune response against HBV. An upsurge of serum HBV DNA usually precedes the rise of alanine aminotransferase (ALT and bilirubin. Whether antiviral treatment can benefit CHB with severe AE remains controversial, but early nucleos(tide analogues treatment seemed to be associated with an improved outcome. There has been no randomized study that compared the effects of different nucleos(tide analogues (NA in the setting of CHB with severe AE. However, potent NAs with good resistance profiles are recommended. In this review, we summarized current knowledge regarding the natural history, pathogenetic mechanisms, and therapeutic options of CHB with severe AE.

    Full Text Available Several government and nongovernment organizations held a consensus conference on the management of acute and chronic viral hepatitis to update previous management recommendations. The conference became necessary because of the introduction of new forms of therapy for both hepatitis B and hepatitis C. The conference issued recommendations on the investigation and management of chronic hepatitis B, including the use of lamivudine, adefovir and interferon. The treatment of hepatitis B in several special situations was also discussed. There were also recommendations on the investigation and treatment of chronic hepatitis C and hepatitis C-HIV coinfection. In addition, the document makes some recommendations about the provision of services by provincial governments to facilitate the delivery of care to patients with hepatitis virus infection. The present document is meant to be used by practitioners and other health care providers, including public health staff and others not directly involved in patient care.

    To evaluate the relationship between the waveform of the right hepatic vein and the histological grade and stage in patients with chronic hepatitis B. Eighty-seven patients with chronic hepatitis B were examined prospectively by one sonographer. In each patient, Doppler waveform of the right hepatic vein was obtained. Doppler waveform was classified into 3 type, type 0; normal triphasic pattern, type 1; reduced amplitude of phasic oscillation and no reverse flow phase, and type 2; completely flat flow pattern. In the same session, an ultrasound guided liver biopsy was performed and submitted to one pathologist for grading and staging. Duplex doppler ultrasonography of the right hepatic vein was also performed in 12 control subjects with no evidence of liver or heart disease. The doppler waveform was compared with the histologic severity and a statistical analysis was performed. In the control group, all cases had type 0 waveform. In the hepatitis group, there were type 0 waveform in 61 cases (70.1%), type 1 waveform in 22 cases (25.3%) and type 2 waveform in 4 cases (4.6%). The frequency of abnormal waveform is significantly higher in patients with grade 3-4 and stage 3-4 than grade and stage 1-2 (p>0.005). In the hepatitis group, the venous pulsatility index (VPI) was 0.17-0.69 (mean 0.41), and decreased in the highest and mean values when increasing the histologic scores. However, it was nor significant statistically (p>0.05). The frequency of abnormal waveform was correlated with the histologic severity in patients with chronic hepatitis B. The highest and mean values of the VPI were also correlated. However 70.1% of the patients with chronic hepatitis B showed normal waveform. So doppler ultrasonogram of the hepatic vein may be useful for the diagnosis and the differential diagnosis from cirrhosis in patients with chronic hepatitis B by combination of doppler waveform and venous pulsatility index.

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

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

    To evaluate changes of the waveform of the hepatic vein on doppler ultrasound (US) in patients with chronic hepatic B and to correlate them with histologic findings. Thirty three patients with chronic hepatic B were prospectively examined with doppler US, and liver biopsy was done at the same time. The right hepatic vein was examined on doppler US, and a liver biopsy was performed in the right lobe of the liver. Doppler waveform was considered abnormal if it showed either reduction in the amplitude of phasic oscillation without the reversed flow phase or the presence of completely flow. Specimens obtained from the biopsy were classified according to the predetermined histologic scoring criteria. It was technically possible to performed Doppler US of the right hepatic vein and liver biopsy simultaneously in all thirty three patients. Waveforms of the right hepatic vein were abnormal in fourteen (42.4%), biphasic in 12 (36.4%) and flat in two (6.0%) patients. Only the steatosis exhibited statistically significant correlation between changes of doppler waveform (p,0.05) of the normal and abnormal groups. Doppler US patterns of the hepatic vein in chronic hepatitis B were different from those of the normal group. The abnormal flow pattern on hepatic venous doppler appeared to be mainly influenced by the intrahepatic fat deposition rather than the degree of fibrosis.

    Objective: To determine the prevalence of hepatitis C virus (HCV) and hepatitis B virus (HBV) infection by detection of anti-HCV and hepatitis B surface antigen (HbsAg) in general population of Pakistan. Materials and Methods: Sera of healthy adult individuals who presented for medical evaluation as a pre-employment criteria in the Gulf region were examined for presence of hepatitis B surface antigen and anti-HCV antibody. Alanine aminotransferase levels were also determined. Results: A total of 47,538 individuals were examined. Out of these, 2528 (5.31%) were positive for anti-HCV and 1221 (2.56%) individuals had positive HBsAg. Hepatitis B surface antigen and anti-HCV both were found in 92 (0.19%) individuals. Mean age of subjects, positive for HCV antibody was 44 years and 40.5 years for HBV. Ninety-four percent individuals were males and 6% were females. Alanine aminotransferase (ALT) was normal in 56% of subjects with positive HCV and 84% of individuals with HBV. Conclusion: This study which evaluated predominantly a healthy male population, showed a high seroprevalence of anti-HCV and average seroprevalence of hepatitis B virus infection. A large majority of these patients was young and had normal ALT. (author)

    BACKGROUND AND AIMS: Chronic hepatitis C virus (HCV) genotype 3 infection with advanced liver disease has emerged as the most challenging to treat. We retrospectively assessed the treatment outcome of sofosbuvir (SOF) based regimes for treatment of HCV genotype 3 infections in a real life setting...... in Scandinavia. METHODS: Consecutive patients with chronic HCV genotype 3 infection were enrolled at 16 treatment centers in Denmark, Sweden, Norway and Finland. Patients who had received a SOF containing regimen were included. The fibrosis stage was evaluated by liver biopsy or transient liver elastography...... was similar for all treatment regimens, but lower in men (p = 0.042), and in patients with decompensated liver disease (p = 0.004). CONCLUSION: We found that sofosbuvir based treatment in a real-life setting could offer SVR rates exceeding 90% in patients with HCV genotype 3 infection and advanced liver...

    Full Text Available Prediction of liver fibrosis progression has a key role in the management of chronic viral hepatitis, as it will be translated into the future risk of cirrhosis and its various complications including hepatocellular carcinoma. Both hepatitis B and C viruses mainly lead to fibrogenesis induced by chronic inflammation and a continuous wound healing response. At the same time direct and indirect profibrogenic responses are also elicited by the viral infection. There are a handful of well-established risk factors for fibrosis progression including older age, male gender, alcohol use, high viral load and co-infection with other viruses. Metabolic syndrome is an evolving risk factor of fibrosis progression. The new notion of regression of advanced fibrosis or even cirrhosis is now strongly supported various clinical studies. Even liver biopsy retains its important role in the assessment of fibrosis progression, various non-invasive assessments have been adopted widely because of their non-invasiveness, which facilitates serial applications in large cohorts of subjects. Transient elastography is one of the most validated tools which has both diagnostic and prognostic role. As there is no single perfect test for liver fibrosis assessment, algorithms combining the most validated noninvasive methods should be considered as initial screening tools.

    Chronic hepatitis C (CHC) infection poses a global healthcare burden, being associated with serious complications if untreated. The prevalence of hepatitis C virus (HCV) infection is highest in areas of Central, South, and East Asia; over 50% of HCV patients worldwide live in the region, where HCV genotypes 1b, 2, 3, and 6 are the most prevalent. Treatment outcomes for chronic hepatitis C vary by ethnicity, and Asian patients achieve higher sustained virologic response rates following interferon (IFN)-based therapy than non-Asians. However, low efficacy, poor safety profile, and subcutaneous administration limit the use of IFN-based therapies. Superior virologic outcomes have been observed with different classes of direct-acting antivirals (DAAs) alone or in combination, and several all-oral DAA regimens are available in Asia. These regimens have shown excellent efficacy and favorable tolerability in clinical trials, yet there is a need for further studies of DAAs in a real world context, particularly in Asia. Furthermore, IFN-free treatment may not be accessible for many patients in the region, and IFN-based regimens remain an option in some countries. There is a need to improve current clinical practices for HCV management in Asia, including effective screening, disease awareness, and prevention programs, and to further understand the cost-effectiveness of IFN-free regimens. The evolution of potent treatments makes HCV eradication a possibility that should be available to all patients. However, access to these therapies in Asian countries has been slow, primarily because of economic barriers that continue to present a hurdle to optimal treatment. © 2016 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

Recently, a new treatment, which is a combination of two direct-acting antiviral agents, ledipasvir 90 mg (anti-NS5A and sofosbuvir 400 mg (anti-NS5B, has been approved in the US and the European Union for the treatment of chronic hepatitis C viral infection. In Phase III trials among chronic hepatitis C virus genotype 1 monoinfected (treatment-naïve, treatment-experienced, and with advanced liver disease or posttransplant patients and HIV–hepatitis C virus coinfected patients, the ledipasvir-sofosbuvir fixed-dose combination is associated with a higher rate of sustained virologic response at 12 weeks after therapy has ceased. According to preliminary data, the ledipasvir-sofosbuvir combination also may be effective against hepatitis C genotype 4 virus infection. The ledipasvir-sofosbuvir combination taken orally is generally well-tolerated. Moreover, the combination treatment may suppress the effect of predictive factors of chronic hepatitis C that have historically been known to be associated with treatment failure. Thus, the fixed-dose single-tablet combination of ledipasvir-sofosbuvir offers a new era for the effective treatment of a variety of patients suffering from chronic hepatitis C virus infection.Keywords: ledipasvir, liver disease, ethnicity, DAA, HIV

Using IFA method the total nitric oxide, endothelin‑1, vasculoendothelial growth factor levels, Willebrand factor (vWF activity were investigated, blood plasma desquamated endotheliocyte (DEC number was calculated with Hladovec method, 1978, thrombocyte aggregation (TA with ADP, collagen, ristocetine was determined.Results. DEC and vWF demonstrated correlation in CHC (p = 0.014 and HC (p = 0.000004. In HC patients reliable correlation of all the investigated indices of endothelium lesion with the thrombocyte number and TA was detected, but in CHC patients no correlations were revealed. Thus, significant elevation of TA with ristocetine was noted only in CHC. Decrease in thrombocyte amount among CHC patients and,especially in HC, and heightened vWF activity could change true TA indices. The corrected TA, whose indices in hepatic diseases significantlyincreased, was calculated taking into account the correction factor vWF / thrombocytes that in CHC did not differ from that of healthy patients and in HC was essentially higher.Conclusion. Endothelium dysfunction markers in CH and HC demonstrate correlation with thrombocyte reduction and TA elevation. Determinationof corrected TA permits to reveal disturbances of thrombocyte hemostasis in the form of elevated aggregation in all CHC and HC patients.

    Full Text Available Abstract Background Hepatitis B and C is common in Pakistan and various risk factors are attributable to its spread. One thousand and fifty consecutive male cases suffering from chronic liver disease (327 HBV and 723 HCV were selected from the OPD of public sector hospital and a private clinic dealing exclusively with the liver patients. To compare the results 723 age and gender matched controls were selected from the blood transfusion services of the public sector hospital. A standard questionnaire was filled for all patients and controls which included the information on possible risk factors. Findings Family history of liver disease was significantly higher (43% and 34% in HBV and HCV positive cases as compared to 5% in controls [odds ratio 15.6; 95% Confidence Interval CI: 10.1 -- 24.1, 10.9; 95% Confidence Interval CI: 7.3 -- 16.4] and same trend was seen for death due to liver disease in the family. Majority 74% hepatitis B positive cases had their shaves done at communal barbers but this practice was equally prevalent amongst controls (68%, thus negating it as a possible risk factor, but there is a significant risk with p Conclusion Injections, surgery and dental treatment appear as major risk factors for the transmission of hepatitis B and C in the community. Massive health care awareness drives need to be done for both health care providers and the public to reduce this menace.

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

     Background. Hepatitis B virus infection and chronic kidney disease are prevalent and remain a major public health problem worldwide. It remains unclear how infection with hepatitis B virus impacts on the development and progression of chronic kidney disease. To evaluate the effect of infection with HBV on the risk of chronic kidney disease in the general population. We conducted a systematic review of the published medical literature to determine if hepatitis B infection is associated with increased likelihood of chronic kidney disease. We used the random effects model of DerSimonian and Laird to generate a summary estimate of the relative risk for chronic kidney disease (defined by reduced glomerular filtration rate and/or detectable proteinuria) with hepatitis B virus across the published studies. Meta-regression and stratified analysis were also conducted. We identified 16 studies (n = 394,664 patients) and separate meta-analyses were performed according to the outcome. The subset of longitudinal studies addressing ESRD (n = 2; n = 91,656) gave a pooled aHR 3.87 (95% CI, 1.48; 6.25, P chronic kidney disease (including end-stage renal disease). No relationship occurred between HBV positive status and prevalent chronic disease (n = 7, n = 109,889 unique patients); adjusted odds ratio, were 1.07 (95% CI, 0.89; 1.25) and 0.93 (95% CI, 0.76; 1.10), respectively. HBV infection is possibly associated with a risk of developing reduced glomerular filtration rate in the general population; no link between HBV sero-positive status and frequency of chronic kidney disease or proteinuria was noted in cross-sectional surveys.

    Hepatitis-C viral infection is a global health problem. It has been estimated that approximately 170 million individuals are infected with hepatitis-C virus. Hepatic steatosis is a frequent histological feature in patients with chronic hepatitis-C infection. Histological examinations show that up to 50% of these patients have variable degrees of hepatic steatosis, even in the absence of other possible steatogenic factors like alcohol, drugs or metabolic syndromes. The objective of this study was to determine the frequency and severity of steatosis in patients with Chronic Hepatitis-C. Methods: This cross sectional study was carried out from 1st January 2010 to 1st July 2010 at the department of Gastroenterology PIMS, Islamabad. A total of 127 patients of chronic hepatitis-C were enrolled in the study after taking informed written consent. Frequency and severity (mild, moderate and severe) of steatosis was assessed on the basis of liver biopsy. Results: A total of 127 patients were included in the study. Mean age of the patients was 36.24 years. Out of 127 patients, 48(38%) were male and 79(62%) were female. Steatosis was present in 50(39%) patients with chronic hepatitis-C infection. whereas steatosis was absent in 77(61%) patients. Conclusion: The presence of steatosis on liver biopsy in patients with chronic hepatitis-C is common (39% patients) and female patients had slightly more severe degree of steatosis as compared to male patients.

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

    Immigrants with chronic hepatitis C (CHC) in Canada have doubled risk of hepatocellular carcinoma. To measure the burden of CHC among immigrants in Canada. A decision analytic model was developed to compare immigrants with CHC and age-matched immigrants without CHC for survival years, quality-adjusted life-years (QALYs) and medical costs per life year. Hepatitis C epidemiology among immigrants was based on hepatitis C prevalence in their home countries. A cohort of immigrant patients was retrospectively followed up to estimate fibrosis stage distribution, treatment patterns and prognosis of compensated cirrhosis. Other model variables were based on published sources. Base case analysis, one-way sensitivity analysis and probabilistic sensitivity analysis were performed to measure the burden of CHC and assess the impact of uncertainty associated with model variables on the burden of CHC. CHC could reduce survival by 9.6 years [95% credible interval (CI): 8.0-10.9 years], reduce QALYs by 9.5 years (95% CI: 6.0-13.8 years) and increase medical costs per life year by $1950 (95% CI: $1518 to $2486, 2006 Canadian dollars). Because nearly half of immigrants with CHC were not diagnosed until the development of cirrhosis, the burden of CHC was highly sensitive to the risks of liver-related complications and mortality but insensitive to pegylated interferon plus ribavirin. The burden of CHC among immigrants in Canada is substantial mainly due to liver-related complications and mortality. The delay in diagnosis was another important contributor to the burden of CHC among immigrants. © 2015 John Wiley & Sons Ltd.

    The currently available drugs to treat hepatitis B virus (HBV) infection include interferons and nucleos(t)ide analogs, which can only induce disease remission and are inefficient for the functional cure of patients with chronic HBV infection (CHB). Since high titers of circulating hepatitis B surface antigen (HBsAg) may be essential to exhaust the host anti-HBV immune response and they cannot be significantly reduced by current drugs, new antiviral strategies aiming to suppress serum hepatitis B surface antigen (HBsAg) could help restore virus-specific immune responses and promote the eradication of the virus. As an alternative strategy, immunotherapy with HBsAg-specific antibodies has shown some direct HBsAg suppression effects in several preclinical and clinical trial studies. However, most described previously HBsAg-specific antibodies only had very short-term HBsAg suppression effects in CHB patients and animal models mimicking persistent HBV infection. More-potent antibodies with long-lasting HBsAg clearance effects are required for the development of the clinical application of antibody-mediated immunotherapy for CHB treatment. Our recent study described a novel mAb E6F6 that targets a unique epitope on HBsAg. It could durably suppress the levels of HBsAg and HBV DNA via Fcγ receptor-dependent phagocytosis in vivo. In this commentary, we summarize the current research progress, including the therapeutic roles and mechanisms of antibody-mediated HBV clearance as well as the epitope-determined therapeutic potency of the antibody. These insights may provide some clues and guidance to facilitate the development of therapeutic antibodies against persistent viral infection.

    PURPOSE: The aim of this study is to investigate the effects of HBsAg vaccine and levamisole on virological indicators in naive patients suffering from chronic hepatitis B (CHB) and in healthy carriers of hepatitis B. METHOD: Vaccination and treatment with levamisole were applied to 93 minor patients in total, 43 of them inactive CHB carriers and 50 patients suffering from CHB. RESULTS: 15 (30%) of 50 patients who had high ALT values in the beginning of the study had normal values after treatment. In nine (12%) patients, posttreatment ALT values were higher than pretreatment values, and six (10%) patients showed HBV-DNA loss. In spite of the presence of 50 (54%) HBeAg-positive patients before treatment, 17 (34%) patients proved to be HBeAg-negative after treatment. HBeAg sero-conversion was seen in 10 (20%) cases. In two (2%) patients, HBsAg sero-conversion occurred. CONCLUSION: It was found that treatment with levamisole and vaccine had positive effects on CHB patients and healthy carriers with respect to HBV DNA loss, HBeAg sero-conversion and ALT normalization. The viral load increases and ALT increases that occurred in certain cases were thought to be related to the early immune response. It was determined that combined levamisole and vaccine therapy had no additional positive effect. PMID:16708498

    Full Text Available The purpose of the study was to examine the clinical and epidemiological data in patients with chronic hepatitis C (CHC and hepatocellular carcinoma (HCC before they sought specialized medical care. The study included 92 patients with CHC. All patients were divided into 2 groups: Group 1 consisted of CHC patients with HCC (n=45, and Group 2 (n=47 consisted of CHC patients without HCC. With the development of HCC in CHC patients, clinical manifestations were absent only in 2.2% of patients. Determining factors in HCC development are male sex, mature age, the maintained HCV replication, moderate and severe fibrosis, disease duration of more than 10 years, and the lack of effect of antiviral treatment.

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

Virological testing is considered to be essential in the management of hepatitis C virus (HCV infection in order to diagnose infection, and, most importantly, as a quide for treatment decisions and assess the virological response to antiviral therapy. The aim of this study was to determine the rate of a sustained virological response (SVR and various factors associated with response rates in chronic hepatitis C infected patients treated with pegiinterferon alpha (PEGINF and ribavirin (RBV combination therapy. Methods. A total of 34 patients, treated with PEG-IFN and RBV were studied. Serum HCV-RNA was measured before the treatment, 12 weeks following the start of the therapy and 6 weeks after the treatment cessation. SVR was defined as undetectable serum HCV-RNA 6 months of post-treatment follow-up, virologic relapse (VR as relapse of HCV-RNA during the post-treatment follow-up. Serum HCV-RNA was measured with the Cobas Amplicor test. Results. At the end of post-treatment follow-up 19 (55.8% patients demonstrated a SVR. The majority of the patients were genotype 1 (27, and the other were genotype 3 (5 patients and genotype 4 (2 patients. There was VR in 6 patients 6 months after the therapy. In 9 patients HCV-RNA was positive after 12 weeks. Conclusion. We demonstrated that patients with chronic HCV infection can be successfully treated with combination of PEG-INF and RBV. This result emphasizes also that post-treatment follow-up to identify patients with SVR or VR could be important.

This prospective cohort study enrolled 174 patients with chronic HCV infection (chronic hepatitis, n = 83; cirrhosis, n = 47; HCC, n = 44), and evaluated disease progression during a mean follow-up of 38.7 mo. OBI was defined as HBV DNA positivity in 2 or more different viral genomic regions by nested polymerase chain reaction using 4 sets of primers in the S, C, P and X open reading frame of the HBV genome. The overall OBI prevalence in chronic HCV patients at enrollment was 18.4%, with 16.9%, 25.5% and 13.6% in the chronic hepatitis C, liver cirrhosis and HCC groups, respectively ( P = 0.845). During follow-up, 52 patients showed disease progression, which was independently associated with aspartate aminotransferase > 40 IU/L, Child-Pugh score and sustained virologic response (SVR), but not with OBI positivity. In 136 patients who were not in the SVR state during the study period, OBI positivity was associated with neither disease progression, nor HCC development. The prevalence of OBI in chronic HCV patients was 18.4%, and OBI was not associated with disease progression in South Koreans.

    Background Hepatitis B virus (HBV) infection has many faces. Precore and core promoter mutants resemble inactive carrier status. The identification of hepatitis B core antigen (HBcAg) in hepatocytes may have variable clinical significance. The present study was undertaken to detect HBcAg in chronic hepatitis B (CHB) patients and to assess the efficacy of detection system by indirect immunofluorescence (IIF) and indirect immunoperoxidase (IIP). Materials and methods The study was done in 70 chronic HBV-infected patients. Out of 70 patients, eight (11.4%) were hepatitis B e antigen (HBeAg) positive and 62 (88.57%) were HBeAg negative. Hepatitis B core antigen was detected by indirect immunofluorescence (IIF) and indirect immunoperoxidase (IIP) methods in liver tissue. Results All HBeAg positive patients expressed HBcAg by both IIF and IIP methods. Out of 62 patients with HBeAg-negative CHB, HBcAg was detected by IIF in 55 (88.7%) patients and by IIP in 51 (82.26%) patients. A positive relation among viral load and HBcAg detection was also found. This was more evident in the case of HBeAg negative patients and showed a positive relation with HBV DNA levels. Conclusion Hepatitis B core antigen can be detected using the IIF from formalin fixed paraffin block preparation and also by IIP method. This seems to reflect the magnitudes of HBV replication in CHB. How to cite this article Raihan R, Tabassum S, Al-Mahtab M, Nessa A, Jahan M, Kabir CMS, Kamal M, Aguilar JC.

    Abstract Patient-reported outcomes (PROs) such as quality of life and work productivity are important for measuring patient's experience. We assessed PROs during and after treatment of hepatitis C virus (HCV) patients. Data were obtained from a phase 3 open label study of sofosbuvir and ribavirin (SOF + RBV) with and without interferon (IFN). Patients completed 4 PRO assessment instruments (SF-36, Functional Assessment of Chronic Illness Therapy—Fatigue, Chronic Liver Disease Questionnaire— HCV, Work Productivity and Activity—Specific Health Problem) before, during, and after treatment. A total of 533 patients with chronic HCV were enrolled; 28.9% treatment-naïve, 23.1% cirrhotic, 219 received IFN + SOF + RBV and 314 received IFN-free SOF + RBV. At baseline, there were no differences in PROs between the IFN-free and IFN-containing treatment arms (all P > 0.05). During treatment, patients receiving IFN + SOF + RBV had a substantial impairment in their PROs (up to −24.4% by treatment week 12, up to −8.3% at week 4 post-treatment). The PRO decrements seen in the SOF + RBV arm were smaller in magnitude (up to −7.1% by treatment week 12), and all returned to baseline or improved by post-treatment week 4. By 12 weeks after treatment cessation, patients who achieved sustained viral response-12 showed some improvement of PRO scores regardless of the regimen (up to +7.1%, P < 0.0001) or previous treatment experience. In multivariate analysis, the use of IFN was independently associated with lower PROs. IFN-based regimens have a profoundly negative impact to PROs. By contrast, the impact of RBV on these PROs is relatively modest. Achieving HCV cure is associated with improvement of most of the PRO scores. PMID:28207507

    Full Text Available Objective: to estimate the time course of changes in the levels of tumor necrosis factor-α (TNF-α, interleukin-4 (IL-4, IL-6, and the hepatic fibrosis indicators hyaluronic acid (HA and liver elasticity index during combined antiviral therapy (AVT with interferon alpha-2b and ribavirin in patients with chronic hepatitis C (CHC. Subjects and methods. Fifty patients with CHC were examined. Serum TNF-α, IL-6, IL-4, and HA were estimated using an enzyme immunoassay. The stage of hepatic fibrosis was determined by fibroelastography with the liver elastic index being measured; the time course of changes in the indicators was assessed in 20 patients at the end of AVT. A virological response was monitored at therapy completion and 6 months later. Results. The patients with CHC in the reactivation phase were found to have enhanced TNF-α, IL-6, and IL-4 activities in 84, 60, and 100 % of the cases, respectively (р < 0.001, р = 0.01, р < 0.001, respectively. The median serum concentration of HA in CHC was 1.8-fold higher than that in the control group (p = 0.03; the liver elastic index averaged 6.5 kPa. TNF-α and IL-6 levels correlated with viremia, transaminases, and hepatic fibrosis indicators. At combined AVT completion, the virological response rate was as high as 85 %, which was attended by a considerable reduction in cytolysis, HA concentrations, and liver density index to 5.4 kPa (3.6–6.8 kPa (p < 0.04, and in the activity of the examined cytokines. The sustained virological response rate was 80 %. Only IL-4 levels decreased and TNF-α and IL-6 concentration remained at the baseline level in patients unresponsive to AVT. Conclusion. It is expedient to monitor TNF-α, IL-4, IL-6, and HA to evaluate the severity of liver involvement in CHC and to predict the efficiency of AVT.

    Objective: To determine the frequency of occurrence of occult Hepatitis B infection in chronic hepatitis C patients and its impact (if any) on the effectivity of standard chronic hepatitis C treatment. Design: Quasi-experimental study. Place and Duration of Study: The study was conducted at the Department of Medicine, Military Hospital, Rawalpindi, and Virology Department, Armed Forces Institute of Pathology, Rawalpindi, for a period of nine months from January 2003 to September 2003. Patients and Methods: This study was conducted on 30 HBsAg negative patients with chronic hepatitis C liver disease who were receiving combination therapy with interferon and ribavirin. Occult hepatitis B infection was assessed by carrying out HBV DNA by polymerase chain reaction (PCR) in the sera of these patients. Markers of previous hepatitis B infection Le; anti-HBs and total anti-HBc antibodies were also tested. Response to treatment for hepatitis C (with interferon and ribavirin) was assessed at the end of six months of therapy by measuring ALT levels and HCV RNA by PCR in the serum. Results: In our study only one patient (3.33%) was found to be harbouring HBV DNA in the serum detectable by PCR, with markers of previous HBV infection (both anti HBc antibodies and anti HBs antibodies were positive). A total 14 patients (46.67%) had markers of previous HBV infection, while 16 patients (53.33%) had no such sero markers. Twenty five out of 30 patients (83.33%) responded to treatment and 5 (16.66%) turned out to be non-responders. The single case of occult hepatitis B detected in this study responded to hepatitis C treatment. Conclusion: Occult hepatitis B is not a common occurrence in chronic hepatitis C patients and it did not alter the outcome of treatment for hepatitis C in our study. (author)

    Many studies have demonstrated a potential association between type 2 diabetes (T2D) and hepatitis C virus infection in Western countries, while similar evidence is limited in Asia. We compared the prevalence of glucose abnormalities (impaired fasting glucose [IFG] and T2D) and their risk factors between Asian and non-Asian chronic hepatitis C (CHC) patients, and evaluated whether glucose abnormalities impacted the viral responses to peginterferon plus ribavirin treatment (current standard of care in most Asian countries). This study retrospectively analyzed data of 1,887 CHC patients from three Phase II/III studies with alisporivir (DEB025) as treatment for CHC. The chi-square test was used to compare the prevalence of IFG/T2D between Asian and non-Asian CHC patients, and logistic regression was used to adjust for sex, age, and cirrhosis status. Risk factors for IFG/T2D were evaluated using univariate and multivariate analysis. Our results indicated that the prevalence of IFG/T2D was high in both Asian and non-Asian CHC patients (23.0% vs 20.9%), and no significant difference was found between these two populations (adjusted odds ratio: 1.3, 95% confidence interval: 0.97, 1.7; P=0.08). Age, sex, and cirrhosis status were risk factors for IFG/T2D in both populations, while body mass index was positively associated with IFG/T2D in non-Asian but not in Asian participants. No significant differences in sustained virological response rates were seen between patients with normal fasting glucose and patients with IFG/T2D for both populations. These results demonstrate that the prevalence of glucose abnormalities in Asian CHC patients was similar to that in non-Asians, and glucose abnormalities had no impact on viral response to peginterferon plus ribavirin.

    Anorexia, nausea, and vomiting are one of the most frequent symptoms in viral hepatitis patients. These may be due to poorly detoxified substances by dysfunctioned hepatocytes or by gastritis, but the pathophysiology is not totally understood. The symptoms interfere with adequate nutrient intake and are managed by metaclopramide, which accelerates gastric emptying. Thus delayed gastric emptying may well be a contributing factor to such symptoms. To determine such a relationship, we measured gastric emptying time in 11 normal subjects, 9 acute (AVH), and 12 chronic B viral hepatitis (CVH) patients. All were males with a mean age of 23 years. An egg was labeled with 0.5 mCi of 99m Tc-sulfur colloid, fried, then eaten between 2 slices of bread with 100 cc of water. Anterior and posterior images were taken at 20 minute intervals over a 2 hour period. A geometric mean of activity pertaining to the gastric region was measured, and T 1 /2 was calculated from the time activity curve. T 1 /2 for normal the group was 57.8 ± 6.3 minutes while that for the AVH and CVH group was 58.2 ± 8.2 (p=0.40) and 64.1 ± 10.5 (p=0.09), respectively. There was 1 AVH patient and 4 CVH patients with prolonged T 1 /2. Anorexia and nausea was seen in 71% and 46% of the patients, respectively. 80% and 60% of the patients with prolonged T 1 /2 had anorexia and nausea, respectively.

    Various autoantibodies have been reported in patients chronically infected by hepatitis C virus. 2% to 10% of theses patients have anti-liver-kidney microsome type 1 (anti-LKM1) autoantibodies. In type 2 autoimmune hepatitis, anti-LKM1 autoantibodies are frequently associated with anti-liver-cytosol type 1 (anti-LC1) autoantibodies. To determine the prevalence of anti-LC1 autoantibodies in a hepatitis C-positive population and characterize their reactivity. 146 patients suffering from liver diseases, of which 99 were chronically infected by hepatitis C virus, were tested by Western blotting and immunoprecipitation to detect and characterize anti-LC1 autoantibodies. 12% of this hepatitis C population had anti-LC1 autoantibodies. LC1 positivity by Western blotting was 30% of LC1+ sera. Epitopes were found throughout the protein but linear epitopes were situated in the 395-541 amino acid region of formiminotransferase cyclodeaminase. Three putative conformational epitopes were identified by phage display. Anti-LC1 autoantibodies are as prevalent as anti-LKM1 autoantibodies in patients infected with hepatitis C virus and their production is not dependent of anti-LKM1 autoantibodies formation. Autoantibody reactivity against the anti-LC1 antigen is different in hepatitis C than in type 2 autoimmune hepatitis. Anti-LC1 autoantibodies can now be regarded as a serological marker of autoimmunity in chronic hepatitis C infection.

    Autoantibodies are often produced during infection with chronic hepatitis C virus (HCV), but it remains controversial whether they influence the biochemical profile and histological features of this disease. Therefore, this current study sought to describe these autoantibodies and evaluate their impact on the clinical and histological presentation of hepatitis C. This cross-sectional analytical study assessed patients with HCV (RNA+) from October 2011 to July 2012. This study included 66 patients, with a mean age of 53.2±10.5 years. Of these patients, 60.6% were male, and 54.3% presented with genotype 1. Non-organ-specific autoantibodies (NOSA) were detected in 24% of the patients; of these, 7.6% were anti-mitochondrial antibodies (AMA+), 26.7% were anti-smooth muscle antibodies (SMA+) and 6.8% were liver kidney microsomal type 1 antibodies (LKM1+). With respect to the thyroid autoantibodies, 7.4% were anti-peroxidase (ATPO+) antibodies, and none were anti-thyroglobulin (ATG+) antibodies. Regarding celiac disease autoantibodies, 5.8% were endomysial antibodies (EMA+), and no transglutaminase (TTG+) antibodies were detected. Cryoglobulins were found in 2.1% of patients. When NOSA+ individuals were compared to patients without the presence of NOSAs, they exhibited higher median alkaline phosphatase (0.7 vs. 0.6 xULN; p=0.041), lower median platelet counts (141,500.0 vs. 180,500.0/mm 3 ; p=0.036), lower mean prothrombin activity (72.6±11.5% vs. 82.2±16.0%; p=0.012) and an increased prevalence of significant fibrosis (E≥2) (45.5% vs. 18.2%; p=0.012). There was also a tendency for a greater proportion of NOSA+ cases to have marked periportal activity (APP≥3) (44.5% vs. 15.6%; p=0.087). In addition to the high prevalence of autoantibodies associated with HCV infection, it was observed that NOSA positivity was associated with a more severe histological and biochemical profile of hepatitis C infection.

    It is generally known that scintigraphy of 99m Tc diethylenetriamine pentaacetic acid-galactosyl human serum albumin ( 99m Tc-GSA) is useful for assessing hepatic functional reserve. For hepatic functional indicators, the index of the calculated planar image has been used in previous studies. However, there have been few reports that suggest that the indicators calculated from static SPECT data would be useful for the assessment of hepatic function. The aims of this study were to establish a simple method for assessing hepatic functional reserve using the liver SPECT of 99m Tc-GSA and to apply this method for rich stratification in patients with chronic hepatic diseases. A liver phantom (a 50% concentration of 99m Tc solution) was used to compare the planar and SPECT methods. According to the definition of the new indicator, the liver SPECT of 99m Tc-GSA was divided by a syringe SPECT of 99m Tc-GSA and was called the liver uptake ratio (LUR). We correlated the LUR and the liver uptake ratio calculated according to the blood-sampling method. 99m Tc-GSA SPECT was performed in 137 patients with hepatic diseases, including chronic hepatic diseases, and 20 healthy volunteers. The LUR was correlated between the formed subtypes for all subjects. The acquired phantom-count ratio calculated by the SPECT method was more accurate than that acquired by the planar method. A good correlation was obtained between the LUR and the blood-sampling method (r=0.971). The LUR was significantly lower in subjects with severe cirrhosis than in healthy subjects or those with chronic hepatitis and mild cirrhosis, and it was significantly lower in subjects with chronic hepatitis and mild cirrhosis than in healthy subjects. The LUR was significantly correlated with other hepatic function tests. Based on LUR, the chronic hepatic diseases were divided into two groups: Group A, with LURs 30% and higher, and Group B, with LURs below 30%. An LUR of 30% marked the 25th percentile of the mild

    Objective: To explore the effect of matrine on reversal of hepatic fibrosis. Methods: Serum hyaluronic acid ( HA), laminin (LN) and type III procollagen (PC III) levels were measured with RIA in 40 patients with chronic B hepatitis treated with matrine and 40 other patients treated without matrine both before and 3, 6 months after treatment as well as in 32 controls. Results: Before treatment, the serum contents of all the three markers in both groups of patients were significantly higher than those in the controls (P 0.05) and increased further at 6 months (vs before treatment, P 0.05), but the levels in the matrine group were significantly lower than those in the group without matrine at 6 months (P < 0.01). Conclusion: Matrine exerts marked anti-fibrosis effect in patients with chronic B hepatitis. (authors)

    Background: Liver biopsy is the standard method for diagnosis of hepatic steatosis, but is invasive and carries some risk of morbidity. Aims and methods: Quantification of hepatocellular lipid content (HCL) with non-invasive single voxel 1 H magnetic resonance spectroscopy (MRS) at 3 T was compared with histological grading and biochemical analysis of liver biopsies in 29 patients with chronic hepatitis C. Body mass index, indices of insulin resistance (homeostasis model assessment index, HOMA-IR), serum lipids and serum liver transaminases were also quantified. Results: HCL as assessed by 1 H MRS linearly correlated (r = 0.70, p 1 H MRS (r = 0.63, p 1 H MRS is a valid and useful method for quantification of HCL content in patients with chronic hepatitis C and can be easily applied to non-invasively monitoring of steatosis during repeated follow-up measurements in a clinical setting.

    Full Text Available In patients with advanced liver cirrhosis due to chronic hepatitis C virus (HCV infection antiviral therapy with peginterferon and ribavirin is feasible in selected cases only due to potentially life-threatening side effects. However, predictive factors associated with hepatic decompensation during antiviral therapy are poorly defined.In a retrospective cohort study, 68 patients with HCV-associated liver cirrhosis (mean MELD score 9.18 ± 2.72 were treated with peginterferon and ribavirin. Clinical events indicating hepatic decompensation (onset of ascites, hepatic encephalopathy, upper gastrointestinal bleeding, hospitalization as well as laboratory data were recorded at baseline and during a follow up period of 72 weeks after initiation of antiviral therapy. To monitor long term sequelae of end stage liver disease an extended follow up for HCC development, transplantation and death was applied (240 weeks, ± SD 136 weeks.Eighteen patients (26.5% achieved a sustained virologic response. During the observational period a hepatic decompensation was observed in 36.8%. Patients with hepatic decompensation had higher MELD scores (10.84 vs. 8.23, p14, respectively. Baseline MELD score was significantly associated with the risk for transplantation/death (p<0.001.Our data suggest that the baseline MELD score predicts the risk of hepatic decompensation during antiviral therapy and thus contributes to decision making when antiviral therapy is discussed in HCV patients with advanced liver cirrhosis.

    In patients with chronic hepatitis C (CHC), superinfection with hepatitis A (HAV) or B (HAB) viruses is associated with increased morbidity and mortality. The seroconversion rate of these patients following vaccination is considered to be lower than in healthy subjects. To evaluate the response to HAV and HBV vaccination in children with CHC. Thirty patients with CHC aged from 7.3 to 18 years were compared with 50 healthy age-, gender- and body-mass-index-matched controls. Post-vaccination serological evaluation was performed 1 month after the last dose of primary vaccination, 1 month after the booster dose and once a year during follow-up. Twenty-two patients received hepatitis A vaccine and response rate was 95.4%. Thirty patients received hepatitis B vaccine and 80% responded (hepatitis Bs titres ≥10 mIU/ml). Thirty-five controls received hepatitis A vaccine and protective anti-HAV antibodies developed in all. All of the controls were vaccinated against hepatitis B virus and 90% responded. After the whole vaccination series, overall seroprotection rates were 86% in patients and 96% in controls. No significant reduction in antibody response was observed in patients or controls during 8-years follow-up. The rate of seroconversion to the HBV vaccine is lower in patients with CHC than in healthy controls but response to HAV is adequate.

    Chinese herbal medicine (CHM) has been commonly used in treating liver diseases in Asian countries. To conduct a large-scale pharmacoepidemiological study and evaluate the frequency and pattern of CHM prescriptions in treating chronic hepatitis. We obtained the database of traditional Chinese medicine outpatient claims from the national health insurance in Taiwan for the whole 2002. Patients with chronic hepatitis were identified by the corresponding diagnosis of International Classification of Disease among claimed visiting files. Corresponding prescription files were analyzed, and association rule were applied to evaluate the co-prescription of CHM in treating chronic hepatitis. Among the 91,080 subjects treated by CHM for chronic hepatitis, the peak age was in the 40 s, followed by 30 s and 50 s. Male/female ratio was 2.07:1. Long-dan-xie-gan-tang and Saliva miltiorrhiza (Dan-shen) were the most commonly prescribed Chinese herbal formula and single herbal drug, respectively. The most common two-drug prescription was Jia-wei-xia-yao-san plus Saliva miltiorrhiza, and the most common three-drug prescription was Jia-wei-xia-yao-san plus Saliva miltiorrhiza and Artemisia capillaries (Yin-chen-hao). This study showed the utilization pattern of Chinese herbal drugs or formulae in treating chronic hepatitis. Further researches and clinical trials are needed to evaluate the efficacy of these Chinese herbs or its ingredients in treating chronic hepatitis.

    We wanted to identify the geographic differences in hepatic fibrosis and their associations with the atrophy-hypertrophy complex in patients with chronic viral hepatitis using the dual-contrast material-enhanced MRI (DC-MRI) with gadopentetate dimeglumine and ferucarbotran. Patients with chronic C (n = 22) and B-viral hepatitis (n = 35) were enrolled for determining the subjective grade of fibrosis (the extent and thickness of fibrotic reticulations) in the right lobe (RL), the caudate lobe (CL), the medial segment (MS) and the lateral segment (LS) of the liver, with using a 5-grade scale, on the gradient echo T2-weighted images of DC-MRI. The fibrosis grades of different segments were compared using the Kruskal-Wallis test followed by post-hoc analysis to establish the segment-by-segment differences. The incidences of two pre-established morphologic signs of cirrhosis were also compared with each other between the two groups of patients. There were significant intersegmental differences in fibrosis grades of the C-viral group (p = 0.005), and the CL showed lower fibrosis grades as compared with the grades of the RL and MS, whereas all lobes were similarly affected in the B-viral group (p = 0.221). The presence of a right posterior hepatic notch was significantly higher in the patients with intersegmental differences of fibrosis between the RL and the CL (19 out of 25, 76%) than those without such differences (6 out of 32, 19%) (p < 0.001). An expanded gallbladder fossa showed no significant relationship (p = 0.327) with the segmental difference of the fibrosis grades between the LS and the MS. The relative lack of fibrosis in the CL with more advanced fibrosis in the RL can be a distinguishing feature to differentiate chronic C-viral hepatitis from chronic B-viral hepatitis and this is closely related to the presence of a right posterior hepatic notch.

    Hepatitis D virus (HDV) infection is associated with a more severe outcome in patients with chronic hepatitis B (CHB); however, little is known about the presence of HDV in sub-Saharan Africa. We aimed to determine the prevalence of HDV infection, as well as its clinical, biological and virological characteristics, in a large CHB cohort in Ethiopia. In total, 1267 HIV-negative CHB patients at St. Paul's Hospital Millennium Medical College in Addis Ababa were screened for anti-HDV antibodies using ELISA assays. Confirmed positive samples were further tested for HDV RNA using a consensus commercial real-time RT-PCR assay. HDV genotypes were also determined for RNA-positive samples by nucleotide sequencing followed by phylogenetic analyses. Demographical, clinical and biological data from patients were recorded and compared based on HDV RNA results. Most patients (n = 748, 59.0%) were men, and the median age was 31 years (interquartile range 26-40). Anti-HDV antibodies were detected in 19 individuals (1.5%), 12 of whom were HDV RNA-positive with a viral load ranging from 8 log 10 IU/mL. All strains were genotype 1. HDV RNA-positive patients were more likely to have significant liver fibrosis (63.6% vs 24.7%, P = .007) and cirrhosis (45.5% vs 16.4%, P = .024). HDV infection is rare in Ethiopia but is associated with more advanced liver fibrosis. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Chronic hepatitis B (CHB) infection is a substantial global health problem with highest prevalence observed in the sub-Saharan Africa and East Asia. India lies in the intermediate endemicity zone with prevalence ranging from 0.1% to 11.7%. The predominant route of transmission is horizontal and the most commonly occurring genotypes are A and D. The high mortality and morbidity associated with CHB constitutes significant health and economic burden in developing countries like India. Antiviral agents decrease HBV DNA load and prevent disease progression. Several regional and country expert associations have developed treatment guidelines for appropriate management of CHB; however, various factors like prevalence, disease awareness, immunization status, cost implications, availability of resources, type of transmission and emerging significance of HBV genotypes have influenced the management of CHB in a country. This article focuses on expert’s recommendations on CHB management including initiation, monitoring and termination of treatment with emphasis on borderline cases. The article also throws light on the challenges to optimum management and provides preferred therapeutic approaches in Indian perspective.

    The incidence of hepatitis A infection in the United States has decreased dramatically in recent years because of childhood immunization programs. A decision analysis of the cost-effectiveness of hepatitis A vaccination for adults with hepatitis C was conducted. No vaccination strategy is cost-effective for adults with hepatitis C using the recent lower anticipated hepatitis A incidence, private sector costs, and a cost-effectiveness criterion of $100,000/QALY. Vaccination is cost-effective only for individuals who have cleared the hepatitis C virus when Department of Veterans Affairs costs are used. The recommendation to vaccinate adults with hepatitis C against hepatitis A should be reconsidered. Published by Elsevier Ltd.

    Transient elastography is widely used to assess fibrosis stage in chronic hepatitis C (CHC). We aimed to establish and validate different transient elastography cut-off values for significant fibrosis and cirrhosis in CHC genotype 4 patients. The data of 100 treatment-naive CHC patients (training set) and 652 patients (validation set) were analysed. The patients were subjected to routine pretreatment laboratory investigations, liver biopsy and histopathological staging of hepatic fibrosis according to the METAVIR scoring system. Transient elastography was performed before and in the same week as liver biopsy using FibroScan (Echosens, Paris, France). Transient elastography results were correlated to different stages of hepatic fibrosis in both the training and validation sets. ROC curves were constructed. In the training set, the best transient elastography cut-off values for significant hepatic fibrosis (≥F2 METAVIR), advanced hepatic fibrosis (≥F3 METAVIR) and cirrhosis (F4 METAVIR) were 7.1, 9 and 12.2 kPa, with sensitivities of 87%, 87.5% and 90.9% and specificities of 100%, 99.9% and 99.9%, respectively. The application of these cut-offs in the validation set showed sensitivities of 85.5%, 82.8% and 92% and specificities of 86%, 89.4% and 99.01% for significant hepatic fibrosis, advanced hepatic fibrosis and cirrhosis, respectively. Transient elastography performs well for significant hepatic fibrosis, advanced hepatic fibrosis and cirrhosis, with validated cut-offs of 7.1, 9 and 12.2 kPa, respectively, in genotype 4 CHC patients.

    Full Text Available 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.

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

    As a noninvasive marker, serum alanine aminotransferase (ALT) has limitations, because a large proportion of patients chronically infected with hepatitis B virus (HBV) suffer from severe hepatic necroinflammation, but have normal or mildly elevated ALT. In the present study, we aimed to investigate the potential value of serum Golgi protein 73 (GP73) in predicting significant hepatic necroinflamation among chronic HBV infected patients. A cohort of 497 chronic HBV infected patients was retrospectively recruited. Liver biopsy was performed in all patients and serum GP73 levels were measured by enzyme-linked immunosorbent assay. Serum GP73 increased in parallel with the increase in hepatic necroinflammatory activity grade (r = 0.682) and the stage of liver fibrosis (r = 0.539). The positive correlation of serum GP73 with the degree of hepatic necroinflammatory activity was statistically significant, while serum GP73 with the stage of liver fibrosis was weaker than that with hepatic necroinflammation. Furthermore, serum GP73 levels were significantly greater in patients with normal or mildly elevated ALT and significant hepatic necroinflammation (≥G2) than in patients with minimal to mild hepatic necroinflammation. The sensitivity and specificity of GP73 for the diagnosis of G2 hepatic necroinflammation was 42.35% and 95.0%, respectively, at a cut-off value of 88.38 ng/mL. When the cut-off value was set at 124.76 ng/mL, the sensitivity and specificity of GP73 for the diagnosis of G3 hepatic necroinflammation was 55.56% and 97.29%, respectively. These findings indicate that GP73 holds promise as an important candidate for diagnosing significant hepatic necroinflammation. © 2018 Wiley Periodicals, Inc.

We compared the prevalence of glucose abnormalities (impaired fasting glucose [IFG] and T2D and their risk factors between Asian and non-Asian chronic hepatitis C (CHC patients, and evaluated whether glucose abnormalities impacted the viral responses to peginterferon plus ribavirin treatment (current standard of care in most Asian countries. This study retrospectively analyzed data of 1,887 CHC patients from three Phase II/III studies with alisporivir (DEB025 as treatment for CHC. The chi-square test was used to compare the prevalence of IFG/T2D between Asian and non-Asian CHC patients, and logistic regression was used to adjust for sex, age, and cirrhosis status. Risk factors for IFG/T2D were evaluated using univariate and multivariate analysis. Our results indicated that the prevalence of IFG/T2D was high in both Asian and non-Asian CHC patients (23.0% vs 20.9%, and no significant difference was found between these two populations (adjusted odds ratio: 1.3, 95% confidence interval: 0.97, 1.7; P=0.08. Age, sex, and cirrhosis status were risk factors for IFG/T2D in both populations, while body mass index was positively associated with IFG/T2D in non-Asian but not in Asian participants. No significant differences in sustained virological response rates were seen between patients with normal fasting glucose and patients with IFG/T2D for both populations. These results demonstrate that the prevalence of glucose abnormalities in Asian CHC patients was similar to that in non-Asians, and glucose abnormalities had

    Background: Liver biopsy is the standard method for diagnosis of hepatic steatosis, but is invasive and carries some risk of morbidity. Aims and methods: Quantification of hepatocellular lipid content (HCL) with non-invasive single voxel {sup 1}H magnetic resonance spectroscopy (MRS) at 3 T was compared with histological grading and biochemical analysis of liver biopsies in 29 patients with chronic hepatitis C. Body mass index, indices of insulin resistance (homeostasis model assessment index, HOMA-IR), serum lipids and serum liver transaminases were also quantified. Results: HCL as assessed by {sup 1}H MRS linearly correlated (r = 0.70, p < 0.001) with histological evaluation of liver biopsies and was in agreement with histological steatosis staging in 65% of the patients. Biochemically assessed hepatic triglyceride contents correlated with HCL measured with {sup 1}H MRS (r = 0.63, p < 0.03) and allowed discriminating between none or mild steatosis versus moderate or severe steatosis. Patients infected with hepatitis C virus genotype 3 had a higher prevalence of steatosis (62%) which was not explained by differences in body mass or whole body insulin resistance. When these patients were excluded from correlation analysis, hepatic fat accumulation positively correlated with insulin resistance in the remaining hepatitis C patients (HCL vs. HOMA-IR, r = 0.559, p < 0.020, n = 17). Conclusion: Localized {sup 1}H MRS is a valid and useful method for quantification of HCL content in patients with chronic hepatitis C and can be easily applied to non-invasively monitoring of steatosis during repeated follow-up measurements in a clinical setting.

    To evaluate the association between insulin resistance and hepatic fibrosis in patients with chronic hepatitis C. A total of 104 chronic hepatitis C patients were included in this non-interventional, open-label, observational, multicenter, cross-sectional study conducted at 20 gastroenterology clinics in Turkey. The primary end point was the correlation between stage of hepatic fibrosis and insulin resistance evaluated via the homeostasis model of assessment-insulin resistance index. Confounders of hepatic fibrosis and insulin resistance were the secondary end points. The mean age of patients was 52.8 years; 65.4% were female. Type 2 diabetes was present in 6.8% and insulin resistance noted in 38.0% of patients. Further, 45.7% of the patients had mild (A0/A1) and the remaining had moderate/severe (A2/A3) hepatic necroinflammatory activity. Patient distribution according to Metavir fibrosis stage was as follows: F0/F1 (57.0%); F2 (6.5%); F3 (23.7%); and F4 (12.9%). A univariate analysis revealed significant positive correlations between Metavir fibrosis stage and insulin resistance (r=0.297; p=0.007). Logistic regression analysis showed that significant predictors of insulin resistance were high alanine transaminase levels (odds ratio, 0.97; 95% confidence interval, 0.944-0.997) and liver fibrosis stage (odds ratio, 0.114; 95% confidence interval, 0.021-0.607). Our findings revealed significant associations between insulin resistance and hepatic fibrosis.

    Full Text Available Background: Hepatitis C virus is encountered sporadically in Bangladesh. It results in a wide range liver diseases, with asymptomatic acute hepatitis rarely at one end to HCC at the other end of the spectrum. Methods: 1018 individuals of different age groups and sex with varied religious, educational and social backgrounds were tested for anti-HCV by ELISA. Before testing, blood samples were preserved at -20°C. The study was conducted in a semi-urban location on the outskirts of Dhaka. Results: 0.88% tested positive for anti HCV. None of them tested positive for HBsAg. There was a male predominance and those who tested positive were mostly between 17 and 50 years of age. Major risk factors for exposure to HBV appeared to be injudicious use of injectable medications, treatment by unqualified, traditional practitioners, mass-vaccination against cholera and smallpox, barbers and body piercing. Conclusion: HCV remains an important cause of morbidity and mortality in Bangladesh. Key words: HCV; prevalence; general population; Bangladesh.DOI: 10.3329/bsmmuj.v2i1.3705 BSMMU J 2009; 2(1: 14-17

    2004-10-01

    Clinical and epidemiological data suggest that generalized anxiety disorder (GAD) is a chronic illness causing patients to suffer for many years leading to significant distress in daily life functioning. The literature suggests the several conclusions. GAD is a disorder in need of appropriate treatment and often has a chronic course with comorbid conditions, such as major depression and other anxiety disorders. Benzodiazepines, while effective anxiolytic agents acutely, when prescribed for >4 weeks cause rebound anxiety and following prolonged therapy may lead to withdrawal symptoms. Antidepressants cause significant anxiety relief compared with placebo and for psychosocial treatment cognitive-behavioral therapy is an efficacious psychosocial treatment. Many GAD patients are in need of long-term medication management. Furthermore, there is limited data for patients diagnosed with GAD the treatment outcome with the combination of medication and psychotherapy both acutely and long-term; how to best sequence these treatments; for those patients who do not meet remission criteria what is the ideal approach for augmentation; and for patients with treatment-refractory GAD the empirical evidence is lacking on medication switching and augmentation strategies. Research is needed in the area of developing treatment strategies for patients suffering from treatment-refractory GAD. There is still an urgent need to explore treatment combinations and duration strategies in the management of patients suffering with GAD.

    The use of direct-acting antivirals (DAAs) to treat chronic hepatitis C has resulted in a significant increase in rates of sustained viral response (around 90%-95%) as compared with the standard treatment of peginterferon/ribavirin. Despite this, however, the rates of therapeutic failure in daily clinical practice range from 10%-15%. Most of these cases are due to the presence of resistant viral variants, resulting from mutations produced by substitutions of amino acids in the viral target protein that reduce viral sensitivity to DAAs, thus limiting the efficacy of these drugs. The high genetic diversity of hepatitis C virus has resulted in the existence of resistance-associated variants (RAVs), sometimes even before starting treatment with DAAs, though generally at low levels. These pre-existing RAVs do not appear to impact on the sustained viral response, whereas those that appear after DAA therapy could well be determinant in virological failure with future treatments. As well as the presence of RAVs, virological failure to treatment with DAAs is generally associated with other factors related with a poor response, such as the degree of fibrosis, the response to previous therapy, the viral load or the viral genotype. Nonetheless, viral breakthrough and relapse can still occur in the absence of detectable RAVs and after the use of highly effective DAAs, so that the true clinical impact of the presence of RAVs in therapeutic failure remains to be determined.

    Full Text Available The aim of this study was to conduct a cost-utility study of adefovir, entecavir, interferon alpha, pegylated interferon alpha, lamivudine and tenofovir for chronic hepatitis B in the context of Brazilian Public Health Care System. A systematic review was carried out for efficacy and safety. Another review was performed to collect utility data and transition probabilities between health states. A Markov model was developed in a time horizon of 40 years with annual cycles for three groups of: HBeAg positive, HBeAg negative, and all patients. These strategies were compared to a fourth group that received no treatment. Discount rates of 5% were applied and sensitivity analyses were performed. Tenofovir offered the best cost-utility ratio for the three evaluated models: U$397, U$385 and U$384 (per QALY, respectively, for HBeAg positive, negative, and all patients. All other strategies were completely dominated because they showed higher costs and lower effectiveness than tenofovir. The sequence of cost-utility in the three models was: tenofovir, entecavir, lamivudine, adefovir, telbivudine, pegylated interferon alpha, and interferon alpha. In the sensitivity analysis, adefovir showed lower cost-utility than telbivudine in some situations. The study has some limitations, primarily related to the creation of scenarios and modeling. In this study, tenofovir presented the best cost-utility ratio. The results obtained in this study will be valuable in decision-making and in the review of the clinical protocol, mainly involving the allocation of available resources for health care.

    Full Text Available Introduction The prevalence of sexual dysfunction (SD and dissatisfaction with sexual life (DSL in patients with chronic hepatitis C virus infection (CHC was jointly investigated via a thorough psychopathological analysis, which included dimensions such as fatigue, impulsiveness, psychiatric comorbidity, health-related quality of life (HRQL and sociodemographic and clinical characteristics. Methods Male and female CHC patients from an outpatient referral center were assessed using the Brief Fatigue Inventory, the Barrat Impulsiveness Scale, the Beck Depression Inventory (BDI, the Hospital Anxiety and Depression Scale, the Hamilton Anxiety Scale (HAM-A, and the World Health Organization Quality of Life Scale-Brief Version (WHOQOL-BREF. Structured psychiatric interviews were performed according to the Mini-International Neuropsychiatric Interview. SD was assessed based on specific items in the BDI (item 21 and the HAM-A (item 12. DSL was assessed based on a specific question in the WHOQOL-BREF (item 21. Multivariate analysis was performed according to an ordinal linear regression model in which SD and DSL were considered as outcome variables. Results SD was reported by 60 (57.1% of the patients according to the results of the BDI and by 54 (51.4% of the patients according to the results of the HAM-A. SD was associated with older age, female gender, viral genotype 2 or 3, interferon-α use, impulsiveness, depressive symptoms, antidepressant and benzodiazepine use, and lower HRQL. DSL was reported by 34 (32.4% of the patients and was associated with depressive symptoms, anxiety symptoms, antidepressant use, and lower HRQL. Conclusions The prevalence of SD and DSL in CHC patients was high and was associated with factors, such as depressive symptoms and antidepressant use. Screening and managing these conditions represent significant steps toward improving medical assistance and the HRQL of CHC patients.

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

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

    Bullous pemphigoid is a type of acute or chronic autoimmune disease that involves subepidermal skin lesions with bulla formation. Although viral infections, such as, human herpes virus (HHV), human immunodeficiency virus, cytomegalovirus, Epstein-Barr virus, HHV-6, hepatitis B virus (HBV), and hepatitis C virus (HCV), are known factors of bullous pemphigoid, HCV infection has only been rarely associated factor, especially in HBV endemic area. A 78-year-old man was admitted to our hospital due to erythematous bulla of onset 3 months before presentation affecting his entire body. Pathologic findings, that is, subepidermal bullae containing eosinophils and neutrophils with superficial perivascular lymphocytic and eosinophilic infiltration, were consistent with bullous pemphigoid. Anti-HCV was positive and HCV quantitative real-time polymerase chain reaction (PCR) was 1.25 x 10 IU/mL. HCV genotype was 2a. After a diagnosis of bullous pemphigoid associated with chronic HCV infection was reached, he was treated with oral methylprednisolone for bullous pemphigoid, and his skin lesions improved. Oral direct-acting antiviral agents (sofosbuvir plus ribavirin) were prescribed for chronic hepatitis C, and sustained viral response was achieved. The authors report a rare case of bullous pemphigoid associated with chronic HCV infection in a HBV endemic area and advise that HCV should be considered in the differential diagnosis of factors precipitating bullous pemphigoid, even in HBV endemic areas.

    Full Text Available Abstract Background Non-alcoholic fatty liver disease (NAFLD, which is characterized by hepatic steatosis, can be reversed by early treatment. Several case reports have indicated that the administration of recombinant growth hormone (GH could improve fatty liver in GH-deficient patients. Here, we investigated whether chronic exogenous GH levels could improve hepatic steatosis induced by a high-fat diet in rats, and explored the underlying mechanisms. Results High-fat diet-fed rats developed abdominal obesity, fatty liver and insulin resistance. Chronic exogenous GH improved fatty liver, by reversing dyslipidaemia, fat accumulation and insulin resistance. Exogenous GH also reduced serum tumour necrosis factor-alpha (TNF-alpha levels, and ameliorated hepatic lipid peroxidation and oxidative stress. Hepatic fat deposition was also reduced by exogenous GH levels, as was the expression of adipocyte-derived adipokines (adiponectin, leptin and resistin, which might improve lipid metabolism and hepatic steatosis. Exogenous GH seems to improve fatty liver by reducing fat weight, improving insulin sensitivity and correcting oxidative stress, which may be achieved through phosphorylation or dephosphorylation of a group of signal transducers and activators of hepatic signal transduction pathways. Conclusions Chronic exogenous GH has positive effects on fatty liver and may be a potential clinical application in the prevention or reversal of fatty liver. However, chronic secretion of exogenous GH, even at a low level, may increase serum glucose and insulin levels in rats fed a standard diet, and thus increase the risk of insulin resistance.

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

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

    Genetic variation within hepatitis B surface antigen (HBsAg), in particular within the major hydrophobic region (MHR), is related to immune/vaccine and test failures and can have a significant impact on the vaccination and diagnosis of acute infection. This study shows, for the first time, variation among acute cases and compares the amino acid variation within the HBsAg between acute and chronic infections. We analyzed the virus isolated from 1231 acute and 585 chronic cases reported to an anonymized public health surveillance database between 2004 and 2014 in The Netherlands. HBsAg analysis revealed the circulation of 6 genotypes (Gt); GtA was the dominant genotype followed by GtD among both acute (68.2% and 17.4%, respectively) and chronic (34.9% and 34.2%, respectively) cases. Variation was the highest among chronic strains compared to that among acute strains. Both acute and chronic GtD showed the highest variation compared to that of other genotypes (P < .01). Substitutions within the MHR were found in 8.5% of the acute strains and 18.6% of the chronic strains. Specific MHR substitutions described to have an impact on vaccine/immune escape and/or HBsAg test failure were found among 4.1% of the acute strains and 7.0% of the chronic strains. In conclusion, we show a high variation of HBsAg among acute and chronic hepatitis B virus-infected cases in The Netherlands, in particular among those infected with GtD, and compare, for the first time, variation in frequencies between acute and chronic cases. Additional studies on the impact of these variations on vaccination and test failure need to be conducted, as well as whether HBsAg false-negative variants have been missed. © 2018 The Authors.

    Insulin resistance is common in patients with chronic liver disease (CLD). Serum levels of soluble vascular adhesion protein-1 (VAP-1) are also increased in these patients. The amine oxidase activity of VAP-1 stimulates glucose uptake via translocation of transporters to the cell membrane in adipocytes and smooth muscle cells. We aimed to document human hepatocellular expression of glucose transporters (GLUTs) and to determine if VAP-1 activity influences receptor expression and hepatic glucose uptake. Quantitative PCR and immunocytochemistry were used to study human liver tissue and cultured cells. We also used tissue slices from humans and VAP-1-deficient mice to assay glucose uptake and measure hepatocellular responses to stimulation. We report upregulation of GLUT1, -3, -5, -6, -7, -8, -9, -10, -11, -12, and -13 in CLD. VAP-1 expression and enzyme activity increased in disease, and provision of substrate to hepatic VAP-1 drives hepatic glucose uptake. This effect was sensitive to inhibition of VAP-1 and could be recapitulated by H2O2. VAP-1 activity also altered expression and subcellular localization of GLUT2, -4, -9, -10, and -13. Therefore, we show, for the first time, alterations in hepatocellular expression of glucose and fructose transporters in CLD and provide evidence that the semicarbazide-sensitive amine oxidase activity of VAP-1 modifies hepatic glucose homeostasis and may contribute to patterns of GLUT expression in chronic disease.

    Full Text Available The endocannabinoid (EC system is implicated in many chronic liver diseases, including hepatitis C viral (HCV infection. Cannabis consumption is associated with fibrosis progression in patients with chronic hepatitis C (CHC, however, the role of ECs in the development of CHC has never been explored. To study this question, anandamide (AEA and 2-arachidonoyl glycerol (2-AG were quantified in samples of HCV patients and healthy controls by gas and liquid chromatography mass spectrometry. Fatty acid amide hydrolase (FAAH and monoaclyglycerol lipase (MAGL activity was assessed by [3H]AEA and [3H]2-AG hydrolysis, respectively. Gene expression and cytokine release were assayed by TaqMan PCR and ELISpot, respectively. AEA and 2-AG levels were increased in plasma of HCV patients, but not in liver tissues. Hepatic FAAH and MAGL activity was not changed. In peripheral blood mononuclear cells (PBMC, ECs inhibited IFN-γ, TNF-α, and IL-2 secretion. Inhibition of IL-2 by endogenous AEA was stronger in PBMC from HCV patients. In hepatocytes, 2-AG induced the expression of IL-6, -17A, -32 and COX-2, and enhanced activation of hepatic stellate cells (HSC co-cultivated with PBMC from subjects with CHC. In conclusion, ECs are increased in plasma of patients with CHC and might reveal immunosuppressive and profibrogenic effects.

    Full Text Available Patients with Down syndrome who received blood transfusions, likely in conjunction with cardiothoracic surgery for congenital heart disease and prior to the implementation of blood-donor screening for hepatitis C virus infection, face a substantial risk of acquiring the infection. In the past, interferon-based therapy for chronic hepatitis C infection in patients with Down syndrome was noted to have lower efficacy and potentially higher risk of adverse effects. Recently, the treatment for chronic hepatitis C has been revolutionized with the introduction of interferon-free direct acting antivirals with favorable safety, tolerability, and efficacy profile. Based on our experiences, the newly approved sofosbuvir-based direct acting antiviral therapy is well tolerated and highly efficacious in this subpopulation of hepatitis C virus infected patients with Down syndrome.

    The relationship between chronic hepatitis C virus infection (HCV) and oral lichen planus (OLP) is a current topic in the field of oral medicine. Many studies of this association have been made over time. The geographic variation of the hepatitis C prevalence proved to be an important factor influencing the statistical results of the studies analyzing the association of the oral plan lichen with the hepatitis C virus. Approaching this issue is not to be neglected. Treatment outcomes in patients with oral lichen planus associated with chronic hepatitis C virus are often unsatisfactory compared to patients suffering from idiopathic oral lichen planus. Also, the evolution of oral lesions is often fluctuating, with repeated periods of relapse according to the degree of liver function decompensation. Background therapy for liver disease itself may influence lichen planus lesions. Thus, during therapy with interferon and ribavirin oral lesions may appear or become acute. PMID:25553136

    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

    More than 20% of chronic hepatitis C (CHC) patients receiving the antiviral therapy with interferonα(IFNα) experience depression, and fluoxetine is often used to alleviate this symptom. Fluoxetine has anti-inflammatory properties and can change the synthesis of liver lipids, but its influence on antiviral therapy for CHC and related mechanism remain unknown. Recent studies show that fluoxetine can inhibit hepatitis C virus (HCV) infection and reduce the production of reactive oxygen species (...

    AIM: To investigate physicians’ knowledge including chronic hepatitis B (CHB) diagnosis, screening, and management in various stages of their training. METHODS: A voluntary 20-question survey was administered in Santa Clara County, CA where Asian and Pacific Islanders (API) account for a third of the population. Among the 219 physician participants, there were 63 interns, 60 second-year residents, 26 chief residents and 70 attending physicians. The survey asked questions regarding respondents’ demographics, general hepatitis B virus knowledge questions (i.e., transmission, prevalence, diagnostic testing, prevention, and treatment options), as well as, self-reported practice behavior and confidence in knowledge. RESULTS: Knowledge about screening and managing patients with CHB was poor: only 24% identified the correct tests to screen for CHB, 13% knew the next steps for patients testing positive for CHB, 18% knew the high prevalence rate among API, and 31% knew how to screen for liver cancer. Wald chi-square analysis determined the effect of training level on knowledge; in all cases except for knowledge of liver cancer screening (P = 0.0032), knowledge did not significantly increase with length in residency training or completion of residency. CONCLUSION: Even in a high-risk region, both medical school and residency training have not adequately prepared physicians in the screening and management of CHB. PMID:26078568

  2. Fanconi syndrome and chronic renal failure in a chronic hepatitis B monoinfected patient treated with tenofovir

    Pedro Magalhães-Costa

    Full Text Available Tenofovir disoproxil fumarate (TDF is one of the first-line treatment options in chronic hepatitis B (CHB. Despite its efficacy in suppressing viral load and a high resistance barrier, long life maintenance therapy is required. Registration studies demonstrated TDF to be a safe drug. However, post-marketing experience reported cases of serious nephrotoxicity associated with hypophosphatemia, osteomalacia and, even more recently, Fanconi syndrome associated with TDF therapy in CHB monoinfected patients. Here the authors report a case of a 40 year-old male, with a CHB monoinfection, that, three years after TDF therapy, developed a progressive chronic kidney disease with a serious hypophosphatemia and a secondary osteomalacia that was manifested by bone pain and multiple bone fractures. Further investigational analyses unveiled a proximal renal tubular dysfunction, which fulfilled most of the diagnostic criteria for a Fanconi syndrome. After TDF withdrawal and oral supplementation with phosphate and calcitriol, his renal function stabilized (despite not returning to normal, proximal renal tubular dysfunction abnormalities resolved as well as osteomalacia. In conclusion, physicians should be aware that, in CHB monoinfected patients under TDF therapy, serious renal damage is possible and preventable by timely monitoring serum creatinine and phosphate.

    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

    Objective: To study the effect of peripheral dendritic cell function on the clinical course and anti-viral treatment in patients with chronic hepatitis B. Methods: Dendritic cells (DCs) were cultured from peripheral blood mononuclear cells (PBMC) and surface markers (phenotype) examined with flow-cytometry in 71 patients with chronic hepatitis B, 17 chronic HBV carriers and 42 controls. Those patients with positive HBV-DNA (57/71) were treated with lamivudine or interferon-α and DCs reexamined after completion of treatment. Results: The expression of DCs phenotypes CD1a and CD86 in chronic hepatitis B patients and chronic carriers were significantly lower than those in controls (P<0.05 or P<0.01). Among the 71 patients, CD1a, CD40, CD80 and CD86 expressions in the 57 HBV - DNA positive patients were all lower than those in the 14 HBV-DNA negative patients, but the difference was significant only in the case of CD86 (P<0.05). After a course of lamivudine treatment (six months, 38 patients), only CD40 expression was significantly increased, but both CD40 and CD86 expressions were significantly higher than those before treatment in the 19 patients treated with interferon-α. Conclusion: DCs function impairment could be demonstrated in patients with chronic hepatitis B, especially in those with positive HBV-DNA. Lamivudine or interferon-α treatment could improve the DCs function. (authors)

    Full Text Available Objective: This study was designed to determine the efficacy and safety of Entecavir (ETV after 96 weeks treatment in patients with chronic viral hepatitis B (CHB. Methods: Thirty-eight patients were included into the study. The criteria for starting ETV treatment were as follows: elevated ALT levels >upper limit of normal (ULN two times, with HBV-DNA levels ≥5 log10 copies/ml (≥20000 IU/mL, in HBe Ag positive patients, ≥4log10 copies/ml (≥2000IU/mL in HBe Ag negative patients and liver damage was confirmed by histopathology (Knodell HAI ≥4 or fibrosis ≥1. Patients were followed up every 12 weeks by virological and biochemical tests. Results: Twenty-four of 38 patients (63.2% were male. Mean age of patients were 38.6 years, 14 of them were HBeAg positive (36.8%. At baseline, median ALT level was detected as 106.7 IU/ml, median HBV DNA levels were 4.8 x 107 copy/ml, and mean Knodell HAI score was nine. Eleven of 14 HBe Ag positive patients (78.6% were treatment-naïve. No resistance mutation was determined during treatment. Biochemical responses (BR at 48 th and 96th week were 100% and virologic response (VR were 57.1%, and 50%, respectively. Serological response (SR at 48th and 96 th weeks were 35.7% and 42.8% respectively. Fifteen (62.5% of 24 HBe Ag negative patients were treatment-naïve; two patients were detected to have lamivudine resistance mutation. At 48 th and 96 th week, BR was 95.8%, and 100%, respectively; and VR were 83.3% both. Conclusion:In our study, virologic response was significantly high after two years of therapy with Entecavir in HBe Ag negative patients. J Microbiol Infect Dis 2013;3(4: 176-180

    To explore the effects of liniment levamisole on cellular immune functions of patients with chronic hepatitis B. The levels of T lymphocyte subsets and mIL-2R in peripheral blood mononuclear cells (PBMCs) were measured by biotin-streptavidin (BSA) technique in patients with chronic hepatitis B before and after the treatment with liniment levamisole. After one course of treatment with liniment levamisole, the levels of CD3(+), CD4(+), and the ratio of CD4(+)/CD8(+) increased as compared to those before the treatment but the level of CD8(+) decreased. The total expression level of mIL-2R in PBMCs increased before and after the treatment with liniment levamisole. Liniment levamisole may reinforce cellular immune functions of patients with chronic hepatitis B.

    Acute on chronic liver failure (ACLF) is rarely the initial manifestation of a malignant process or precipitated by the initiation of anti-viral treatment with a nucleoside or nucleotide agent. We report an unusual case of ACLF temporally associated with initiation of Entecavir for treatment of chronic hepatitis B. Early Hodgkin’s lymphoma (HL) was unmasked with initiation of the anti-viral treatment which may have exacerbated ACLF. To the best of our knowledge, this has not been described in the literature. In reviewing our patients clinical course and liver autopsy, he developed a severe acute exacerbation of his chronic hepatitis B virus coinciding with the institution of antiviral therapy and the underlying HL perhaps modulating the overall degree of hepatic injury.

    2005-01-01

    Full Text Available Background. It has been established that many patients with chronic hepatitis C have elevated serum iron, feritin levels and iron deposits in the liver. Therefore, the liver damage due to hepatitis C virus may be aggravated with iron overload. In many studies higher levels of iron in the blood and the liver were connected with the decreased response to interferon-alfa therapy for chronic viral hepatitis C. Recent introduction of pegylated interferons plus ribavirin has improved the therapeutic response, so it is now possible to cure more than 50% of the patients. Case report. Three patients with chronic hepatitis C and iron overload were presented. Iron reduction therapy using phlebotomy or eritrocytapheresis with plasmapheresis was done at different times in regard to specific antiviral therapy or as a sole therapy. Conclusion. It has been shown that iron reduction, sole or combined with antiviral therapy, led to the deacreased aminotransferase serum activity and might have slow down the evolution of chronic hepatitis C viral infection.

    To describe a case of autosomal-dominant (AD)-chronic mucocutaneous candidiasis (CMC) with a signal transducer and activator of transcription (STAT) 1 gene mutation, and some of the important complications of this disease such as chronic hepatitis. We present a 23-year-old woman with CMC, chronic active hepatitis, and hypothyroidism. Her father also had CMC. We performed several immunological analyses of blood and liver samples, and searched for gene mutations for CMC in the patient and her father. We identified the heterozygous substitution c.821 G > A (p.Arg274Gln) in the STAT1 gene of both the patient and her father. The level of β-glucan induced interferon (IFN)-γ in her blood cells was significantly low. Immunoblot analysis detected serum anti-interleukin (IL)-17 F autoantibody. She was found to have increased (low-titer) antibodies related to her hypothyroidism and hepatitis. Her serum IL-18 levels fluctuated with her AST and ALT levels. Liver biopsy revealed CD68-positive cell infiltration and IL-18 expression in the sinusoidal regions. These results suggest that the chronic active hepatitis in this patient may be exacerbated by the excessive IL-18 accumulation caused by recurrent mucocutaneous fungal infection, and decreased IFN-γ production. AD-CMC is known to be caused by a gain-of-function mutation of the STAT1 gene. Chronic active hepatitis is a rare complication of AD-CMC, with currently unknown pathogenesis. It seems that the clinical phenotype in this patient is modified by autoimmune mechanisms and cytokine dysregulation. AD-CMC can be complicated by various immune disorders including autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy.

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

    Full Text Available Background. Recent data suggest that chronic hepatitis C has to be considered a metabolic disease further to a viral infection. The aim of this study was to elaborate on the complex interactions between hepatitis C virus, host metabolic factors, and treatment response. Methods. Demographic, virological, and histological data from 356 consecutive patients were analyzed retrospectively. Hepatic steatosis, obesity, and insulin resistance were examined in relation to their impact on treatment outcome. Comparison between genotype 1 and 3 patients was performed to identify differences in the determinants of hepatic steatosis. Results. Histological evidence of hepatic steatosis was found in 113 patients, distributed in 20.3%, 9.0%, and 2.5% for grades I, II, and III, respectively. Hepatic steatosis was associated with past alcohol abuse (P=0.003 and histological evidence of advanced fibrosis (P<0.001. Older age (OR 2.51, P=0.002, genotype (OR 3.28, P<0.001, cirrhosis (OR 4.23, P=0.005, and hepatic steatosis (OR 2.48, P=0.001 were independent predictors for nonresponse. Correlations of hepatic steatosis with alcohol, insulin resistance, and fibrosis stage were found similar for both genotypes 1 and 3. Conclusions. Host metabolic factors may predict treatment outcome, and this impact remains significant even in genotype 3, where steatosis has been believed to be exclusively virus related.

    Full Text Available Aim: This study was performed to evaluate the diagnostic value of hepatocyte-derived microRNA (miRNA-122 in acute and chronic hepatitis of dogs. Materials and Methods: A total of 26 dogs presented at Veterinary Teaching Hospital, Faculty of Veterinary Medicine, Cairo University, 16 dogs out of 26 showing clinical signs of hepatic insufficiency were subjected to clinical, ultrasonographic, hematobiochemical and ultrasound-guided fine-needle biopsy for cytological and histopathological investigations. On the basis of these results, 7 dogs out of 16 dogs were found to be suffering from acute hepatitis and 9 dogs suffering from chronic hepatitis. 10 clinically healthy dogs were kept as control. Serum hepatocyte-derived miRNA-122 was analyzed by real-time quantitative polymerase chain reaction in all dogs. Results: The dogs suffering from acute hepatitis manifested jaundice, vomiting, and depression while dogs with chronic hepatitis manifested anorexia, abdominal distension, weight loss, and melena. Hematological parameters showed normocytic normochromic anemia and thrombocytopenia in both acute and chronic hepatitis groups. Alanine aminotransferase (ALT, aspartate aminotransferase (AST, alkaline phosphatase (ALP, and total bilirubin were significantly higher than control values in acute hepatitis. In chronic hepatitis, total protein and albumin were significantly lower than control values with normal ALT, AST, ALP, and gamma-glutamyltransferase values. Ultrasonography revealed a diffuse decrease in hepatic echogenicity in acute hepatitis while the increase in hepatic echogenicity and anechoic ascetic fluid in chronic hepatitis. Cytology revealed hepatic vacuolar degeneration and histopathology revealed necrosis and apoptosis of hepatocyte in acute hepatitis while revealed massive fibrous tissue proliferation in hepatic parenchyma in chronic hepatitis.

    To investigate the genetic variation and typing of hepatitis B virus (HBV) in patients with chronic hepatitis B in relation to HBeAg status. Fluorescence quantitative polymerase chain reaction (PCR) was employed to detect serum HBV DNA in patients with chronic hepatitis B negative for HBeAg. Real-time fluorescent PCR and PCR-reverse dot blot hybridization were used to detect HBV genotypes and mutations, respectively. Of the 389 patients, 214 (55.01%) were positive and 175 (44.99%) were negative for HBV DNA; 102 (26.22%) had a HBV DNA copy number of 1×10(3), and 41 (10.54%) had a copy number of 1×10(4) (Χ(2)=226.6729, Ptype were found in 6 (2.80%), 84 (39.25%), 106 (49.53%), and 7 (3.27%), and 11 (5.14%) patients, who showed precore mutation rates of 16.67% (1 case), 36.90% (31 cases), 44.34% (47 cases), 0, and 0, and BCP mutation rates of 0, 19.05% ( 16 cases), 26.42% (28 cases), 0, and 0, respectively, demonstrating significant differences in HBV mutations between the genotype groups (P<0.001). HBeAg-negative and HBV DNA-positive patients with chronic hepatitis B have a relatively low HBV replication level, and HBV DNA load is associated with HBV mutations. The B and C genotypes are more likely to have HBV mutations in HBeAg-negative patients.

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

    Full Text Available ObjectiveTo evaluate the value of transient elastography (FibroScan, FS in predicting hepatic fibrosis in patients with HBeAg-negative chronic hepatitis B (CHB. MethodsOne hundred and four patients with HBeAg-negative CHB, who were diagnosed and treated in Hubei Hospital of Traditional Chinese Medicine from June 2011 to May 2013, were enrolled in this study. All patients underwent FS for liver stiffness measurement before liver biopsy. Statistical analysis was applied to compare liver stiffness (kPa with fibrosis stage (determined by liver biopsy. The receiver operating characteristic (ROC curve of FS was constructed, and the area under the ROC curve (AUROC was calculated to analyze the accuracy of live stiffness in predicting significant fibrosis and cirrhosis. Comparison between groups was made by Kruskal-Wallis H test, followed by Mann-Whitney U test for multiple comparisons. The correlation between two variables was analyzed by Spearman rank and Pearson correlation test. ResultsLiver stiffness gradually rose as the degree of hepatic fibrosis increased, with significant differences between groups (P<0.01 or P<0.05. Liver stiffness was positively correlated with the stage of hepatic fibrosis (r=0.810, P<0.01. The AUROC of liver stiffness for detecting liver cirrhosis was 0.956; the cut-off value for diagnosing liver cirrhosis was 13.1 kPa; the sensitivity was 92.7%, and the specificity was 80%. ConclusionFS is a promising noninvasive method for the assessment of hepatic fibrosis in patients with HBeAg-negative CHB; particularly, it has high accuracy in the diagnosis of liver cirrhosis. FS combined with direct or indirect markers may play an important role in differential diagnosis and efficacy evaluation in patients with hepatic fibrosis.

    Patient education is crucial in improving the health-related quality of life (HRQOL) of patients. At the same, understanding the concerns and needs of patients is essential in providing appropriate education. This study assessed the educational needs and HRQOL experienced by chronic hepatitis patients. We developed structured questionnaires with satisfactory validity and reliability to assess the educational needs of patients. HROQL was measured using a generic Short Form 36 (SF-36) and a liver disease-specific Chronic Liver Disease Questionnaire (CLDQ). Descriptive statistic measures and Pearson's correlation analysis were applied for data analysis. A total of 135 subjects were recruited from two regional teaching hospitals in Taiwan. "Disease characteristics and management" exhibited the highest mean score (3.17) among all the subscales of educational needs. In comparison with those without antiviral therapy, chronic hepatitis patients undergoing antiviral treatment scored significantly higher on all subscales of educational needs, especially on "side effects of antiviral treatment" (p educational needs were significantly inversely correlated with the CLDQ and SF-36 subscales. Education is highly required by chronic hepatitis patients, especially those receiving antiviral therapy and patients with poor HRQOL. These findings can serve as a useful reference for nursing personnel who perform needs assessment to develop individual nursing instruction and thereby improve the quality of care for chronic hepatitis patients.

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

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

    Full Text Available Background: Chronic ethanol ingestion causes hepatic damage imputable to an increasedoxidative stress engendered by alcoholic toxicity. Polyphenols in cocoa have antioxidant properties, and natural cocoa powder (NCP contains the highest levels of total antioxidant capacity when compared to all other kinds of edible cocoa products. This study tested the hypothesis that dietary supplementation with NCP mitigates hepatic injury resulting from chronic ethanol consumption. Three groups of eight randomized Sprague-Dawley rats were fed standardrat food and treated daily for 12 weeks as follows: (i the Ethanol-water group was given unrestricted access to 40% (v/v ethanol for 12 hours (at night followed by water for the remaining 12 hours (daytime, (ii the Ethanol-cocoa group had similarly unrestricted access to 40% ethanol for 12 hours followed by 2% (w/v NCP for 12 hours, and (iii the control group was not given alcohol and had unrestricted access to only water which was synchronously replenished every 12 hours as it was for the ethanol treated animals.Results: Qualitative structural liver damage evidenced by hepatocyte cytoplasmic fatty accumulation, nuclear alterations, and disruption of general liver micro-architecture, was severe in the ethanol-water group when compared with the ethanol-cocoa group of rats. Design-based stereologic assessment yielded a significantly greater volume (Tukey’s HSD, p = 0.0005 ofundamaged hepatocytes (9.61 ml, SD 2.18 ml in the ethanol-cocoa group as opposed to theethanol-water group of rats (2.34 ml, SD 1.21 ml.

    The authors examined the methylation status of CCGG sites in hepatitis B virus (HBV) DNA to determine whether methylation could be responsible for the selective expression of the HBV surface gene in chronic hepatitis B infection and hepatocellular carcinoma. Infected liver tissue from patients with low levels of viral replication was analyzed for HBV DNA copy number per haploid cell genome. Total cellular DNA, with sufficient HBV DNA, was digested with the restriction endonucleases Msp I and Hpa II, to determine whether the HBV DNA was methylated, or HindIII, to determine whether the HBV DNA was integrated or episomal. The cleavage fragments were analyzed by Southern blotting and hybridization to 32 P-labeled HBV DNA. In replicative chronic hepatitis B, hypomethylation of the HBV genome correlated with HBV expression in both virions and infected tissue. In carriers with nonreplicative infection, it was difficult to ascertain the role of methylation as copy number was low. HBV DNA copy number was also low in 17 out of 29 of the rumor tissues tested and as many as 14 out of 16 of the adjacent non-neoplastic tissues tested. Integrated sequences were hypermethylated in the PLC/PRF/5 cell line and in six of the tumor tissues suggesting that methylation plays a role in HBV gene repression. However, since DNA from five other tumors was hypomethylated, the belief that methylation per se is an absolute determinant of HBV core gene repression does not hold for human hepatocellular carcinoma tissue

    To detect hepatic insulin receptor substrate 2 in chronic hepatitis C patients. Study Design: Comparative study. Place and Duration of Study: Center for research in experimental and applied medicine (CREAM), Department of Biochemistry and Molecular Biology, Army Medical College and Holy Family Hospital Rawalpindi, from Dec 2011 to Nov 2012. Diagnosed patients of chronic hepatitis C were included in the study. Known cases of diabetes mellitus, patients with pancreatic disease and liver pathology other than hepatitis C were excluded from the study. Material and Methods: Twenty seropositive non diabetic HCV infected patients and 10 control subjects were recruited. Liver biopsy specimen was obtained from seropositive HCV patients while blood samples were obtained from controls as biopsy sample was not possible from normal controls. Both types of speciens were studied for detection of insulin receptor substrate 2 (IRS-2). Results: No alteration in the content of insulin receptor substrate 2 in both seropositive patients and control samples were detected. Conclusion: Hepatitis C virus has no effect on insulin receptor substrate 2 content thus indicating absence of hepatic insulin resistance in patients with HCV infection. (author)

TAF has been shown to be a potent inhibitor of HBV replication at a low dose, with high intracellular concentration and more than 90% lower systemic TFV concentration than tenofovir disoproxil fumarate (TDF. In two randomized, double-blind, multinational, Phase 3, non-inferiority trials for hepatitis B e antigen (HBeAg-positive and -negative patients (primary analysis: 48 weeks, TAF 25 mg orally once-daily was not inferior to TDF 300 mg in achieving an HBV DNA level <29 IU/mL at week 48. No amino-acid substitutions associated with viral breakthrough were detected by deep sequencing, and no resistance to TAF was found through week 96. In addition, no difference in the frequency of HBeAg or hepatitis B surface antigen loss was observed. However, TAF was associated with a significantly higher ALT normalization rate than was TDF, based on the American Association for the Study of Liver Diseases criteria (male: ALT ≤30 U/L and female: ALT ≤19 U/L. An analysis of renal safety showed that patients treated with TAF had a significantly lower decrease in the estimated glomerular filtration rate level than did patients treated with TDF. Similarly, the declines of hip and spine bone mineral density were significantly less in the TAF group. These trends of efficacy and renal/bone safety continued through week 96. Longer term follow-up and real-world data will be required to determine if the differences in viral/biochemical response and renal/bone safety seen with TAF in comparison with TDF are clinically relevant.

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

    Transfusion transmitted virus (TTV) is an enveloped single strand virus discovered in serum of patients with post-transfusion hepatitis of unknown etiology in Japan and designated as TT virus (TTV). To investigate the frequency of TTV infection in patients with viral hepatitis B or C, 25 Egyptian patients with hepatitis C virus (HCV) aged 8-40 years and 25 patients with B virus (HBV) aged 8-57 years were tested. Detection of TTV-DNA was performed by semi-nested polymerase chain reaction (PCR) using TTV-specific primers. Serum levels of transaminases were tested. The prevalence of TTV in patients with chronic viral hepatitis B or C was frequent and the co-infection of TTV with HCV or HBV was accompanied by a high level of transaminases as compared to that of HBV or HCV alone. The present study confirms and extends that infection alone doesn't cause significant liver damage

    Radioimmunoassay plays an important role in diagnosing the hepatitis B and in clinical assessment of the course of the disease as well. Among a number of antigens, antibodies and enzymes related with hepatitis, HBe Ag, DNA polymerase, IgM-HBc-antibody, {delta} Ag have been known as useful indicators of ongoing infectivity of hepatitis B. The present study has been undertaken to correlate the HBe antigenicity with hepatospleno-scintigraphic findings in hepatitis. The study covered a 10 month period from September 1982 through to July 1983. We reviewed and analyzed the hepatospeno-scintgraphic findings and the results of radioimmuassays in 32 patients of chronic hepatitis seen at St. Mary Hospital, Catholic Medical College. Hepatitis B was diagnosed either when HBs Ag was positive or Anti-HBc wa positive even if HBs Ag was negative. We classified the HBe antigenicity into two groups of HBe Ag(+) and HBe(-) and analyzed the scintgraphic findings in terms of liver size, motting, splenomegaly and splenic shift. From the present study, it is concluded that the activity of hepatitis B can not be assessed by the findings of hepatospleno-scintigram so far as the activity is determined on the basis of the positive HBe Ag, which has been believed to indicated continuing viral replication.

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

    To investigate the association of chronic hepatitis B and nonalcoholic steatohepatitis with physical fitness in a Taiwanese military male cohort. We made a cross-sectional examination of this association using 3669 young adult military males according to cardiorespiratory fitness and hospitalization events recorded in the Taiwan Armed Forces study. Cases of chronic hepatitis B ( n = 121) were defined by personal history and positive detection of hepatitis B surface antigen. Cases of nonalcoholic steatohepatitis ( n = 129) were defined by alanine transaminase level > 60 U/L, liver ultrasound finding of steatosis, and absence of viral hepatitis A, B or C infection. All other study participants were defined as unaffected ( n = 3419). Physical fitness was evaluated by performance in 3000-m run, 2-min sit-ups, and 2-min push-ups exercises, with all the procedures standardized by a computerized scoring system. Multiple linear regression analysis was used to determine the relationship. Chronic hepatitis B negatively correlated with 2-min push-up numbers (β = -2.49, P = 0.019) after adjusting for age, service specialty, body mass index, systolic and diastolic blood pressures, current cigarette smoking, alcohol intake status, serum hemoglobin, and average weekly exercise times. Nonalcoholic steatohepatitis was borderline positively correlated with 3000-m running time (β = 11.96, P = 0.084) and negatively correlated with 2-min sit-up numbers (β = -1.47, P = 0.040). Chronic hepatitis B viral infection and nonalcoholic steatohepatitis affects different physical performances in young adult military males, and future study should determine the underlying mechanism.

  3. Hepatitis B viral factors and treatment responses in chronic hepatitis B

    2013-06-01

    Full Text Available Baseline and on-treatment hepatitis B viral factors are reported to affect treatment responses. A lower baseline hepatitis B virus (HBV DNA level is a strong predictor of the response to antiviral therapy. HBV genotype A/B patients have better responses to interferon-based therapy than those with genotypes C/D. Regarding the association of HBV mutants with responses to antiviral therapy, current evidence is limited. On-treatment viral suppression is the most important predictor of response to nucleoside analogs. On-treatment hepatitis B surface antigen decline is significantly associated with response to pegylated interferon. In the future, individualized therapy should be based on treatment efficacy, adverse effects, baseline and on-treatment predictors of antiviral therapy.

    Hepatic fibrosis is a common middle stage of the pathological processes of chronic liver diseases. Clinical intervention during the early stages of hepatic fibrosis can slow the development of liver cirrhosis and reduce the risk of developing liver cancer. Performing a liver biopsy, the gold standard for viral liver disease management, has drawbacks such as invasiveness and a relatively high sampling error rate. Real-time tissue elastography (RTE), one of the most recently developed technologies, might be promising imaging technology because it is both noninvasive and provides accurate assessments of hepatic fibrosis. However, determining the stage of liver fibrosis from RTE images in a clinic is a challenging task. In this study, in contrast to the previous liver fibrosis index (LFI) method, which predicts the stage of diagnosis using RTE images and multiple regression analysis, we employed four classical classifiers (i.e., Support Vector Machine, Naïve Bayes, Random Forest and K-Nearest Neighbor) to build a decision-support system to improve the hepatitis B stage diagnosis performance. Eleven RTE image features were obtained from 513 subjects who underwent liver biopsies in this multicenter collaborative research. The experimental results showed that the adopted classifiers significantly outperformed the LFI method and that the Random Forest(RF) classifier provided the highest average accuracy among the four machine algorithms. This result suggests that sophisticated machine-learning methods can be powerful tools for evaluating the stage of hepatic fibrosis and show promise for clinical applications.

    Coinfection with hepatitis A virus (HAV) or hepatitis B virus (HBV) in patients with chronic hepatitis C virus (HCV) is associated with increased morbidity and mortality. The Center for Medicare and Medicaid Services has identified HAV and HBV vaccination as a priority area for quality measurement in HCV. It is unclear to what extent patients with HCV meet these recommendations. We used national data from the Department of Veterans Affairs HCV Clinical Case Registry to evaluate the prevalence and predictors of meeting the quality measure (QM) of receiving vaccination or documented immunity to HAV and HBV in patients with chronic HCV. We identified 88,456 patients who had overall vaccination rates of 21.9% and 20.7% for HBV and HAV, respectively. The QM rates were 57.0% and 45.5% for HBV and HAV, respectively. Patients who were nonwhite or who had elevated alanine aminotransferase levels, cirrhosis, or human immunodeficiency virus were more likely to meet the HBV QM. Factors related to HCV care were also determinants of meeting the HBV QM. These factors included receiving a specialist consult, genotype testing, or HCV treatment. Patients who were older, had psychosis, and had a higher comorbidity score were less likely to meet the HBV QM. With a few exceptions, similar variables were related to meeting the HAV QM. The incidence of superinfection with acute HBV and HAV was low, but it was significantly lower in patients who received vaccination than in those who did not. Quality measure rates for HAV and HBV are suboptimal for patients with chronic HCV. In addition, several patient-related factors and receiving HCV-related care are associated with a higher likelihood of meeting QMs. Copyright © 2010 American Association for the Study of Liver Diseases.

    To evaluate the diagnostic performance of magnetic resonance elastography (MRE) for staging hepatic fibrosis in patients with chronic hepatitis B virus (HBV) infection. Patients with chronic HBV infection who were suspected of having focal or diffuse liver diseases (n = 195) and living donor candidates (n = 166) underwent MRE as part of the routine liver MRI examination. We measured liver stiffness (LS) values on quantitative shear stiffness maps. The technical success rate of MRE was then determined. Liver cell necroinflammatory activity and fibrosis were assessed using histopathologic examinations as the reference. Areas under the receiver operating characteristic curve (Az) were calculated in order to predict the liver fibrosis stage. The technical success rate of MRE was 92.5% (334/361). The causes of technical failure were poor wave propagation (n = 12), severe respiratory motion (n = 3), or the presence of iron deposits in the liver (n = 12). The mean LS values, as measured by MRE, increased significantly along with an increase in the fibrosis stage (r = 0.901, p < 0.001); however, the mean LS values did not increase significantly along with the degree of necroinflammatory activity. The cutoff values of LS for ≥ F1, ≥ F2, ≥ F3, and F4 were 2.45 kPa, 2.69 kPa, 3.0 kPa, and 3.94 kPa, respectively, and with Az values of 0.987-0.988. MRE has a high technical success rate and excellent diagnostic accuracy for staging hepatic fibrosis in patients with chronic HBV infection.

    Full Text Available Introduction: Hepatitis C is a major health problem: approximately 170 million people are infected with the hepatitis C virus worldwide. It is unclear whether chronic hepatitis C affects atherosclerosis and whether it can cause endothelial and/or autonomic nervous system (ANS dysfunction. Materials and methods: From April 2008 through April 2009, we studied 76 patients with biopsyconfirmed chronic hepatitis C and no evidence of cirrhosis, ascites, portal hypertension, encephalopathy, or hepatocellular carcinoma. The age-, sex-, BMI- and cardiovascular risk factor- matched control group comprised 76 healthy, HCV-negative individuals with no evidence of liver, autoimmune, or immunoproliferative diseases and no history of cardiovascular events. Twenty five of the hepatitis C patients were treatment-naive; the other 51 had been treated with interferon (but only 25 had persistent virological responses. Color Doppler sonography was used to measure the intima-media-thickness (IMT of the common and internal carotid arteries. Endothelial function was assessed in the brachial artery with the flow-mediated-dilatation (FMD test. The ANS was assessed with the tilt, laying to standing, Valsalva, hand grip, deep breath, and stroop tests. Results: The case group (mean age 52 + 13 years had a significantly higher internal carotid IMT (0.86 + 0.3 vs 0.67 + 0.1 mmfor controls; p = 0.002. Chronic hepatitis C was also associated with an odds ratio for carotid plaque formation (reflected by an IMT > 1.3 mm of 2.15. Cases also had significantly reduced FMD in the brachial artery (0.46 + 0.9 vs 0.76 + 0.7 for controls; p = 0.005 and significantly altered sympathetic and parasympathetic function (p = 0.001 vs controls in the Valsalva, hand grip, deep breath, and stroop tests. Within the case group, all alterations were more severe in patients with significant viremia. Discussion: Our findings suggest that chronic hepatitis C may be a nonclassic cardiovascular risk

    Highlights: • Hepatic contour was quantified and converted to hepatic fibrosis index (HFI). • HFI was a significant risk factor for HCC with an odds ratio of 26.4. • HFI may be an important imaging biomarker for managing cirrhotic patients. - Abstract: Purpose: To evaluate whether a hepatic fibrosis index (HFI), quantified on the basis of hepatic contour abnormality, is a risk factor for the development of hepatocellular carcinoma (HCC) in patients with chronic hepatitis C. Materials and methods: Our institutional review board approved this retrospective study and written informed consent was waved. During a 14-month period, consecutive 98 patients with chronic hepatitis C who had no medical history of HCC treatment (56 men and 42 women; mean age, 70.7 years; range, 48–91 years) were included in this study. Gadoxetic acid-enhanced hepatocyte specific phase was used to detect and analyze hepatic contour abnormality. Hepatic contour abnormality was quantified and converted to HFI using in-house proto-type software. We compared HFI between patients with (n = 54) and without HCC (n = 44). Serum levels of albumin, total bilirubin, aspartate transferase, alanine transferase, percent prothrombin time, platelet count, alpha-fetoprotein, protein induced by vitamin K absence-II, and HFI were tested as possible risk factors for the development of HCC by determining the odds ratio with logistic regression analysis. Results: HFIs were significantly higher in patients with HCC (0.58 ± 0.86) than those without (0.36 ± 0.11) (P < 0.001). Logistic analysis revealed that only HFI was a significant risk factor for HCC development with an odds ratio (95% confidence interval) of 26.4 (9.0–77.8) using a cutoff value of 0.395. Conclusion: The hepatic fibrosis index, generated using a computer-aided assessment of hepatic contour abnormality, may be a useful imaging biomarker for the prediction of HCC development in patients with chronic hepatitis C.

Our aim was to assess liver fibrosis in Egyptian hemodialysis (HD patients infected with CHC genotype 4 using a fibroscan. This cross-sectional observational study was conducted over two years on a cohort of 134 Egyptian patients on prevalent HD at Kasr Al Ainy Hospital. All patients were subjected to routine laboratory evaluation including, hepatitis B surface antigen, hepatitis B core antibody, hepatitis Be antigen, hepatitis C antibody (HCVAb and human immunodeficiency virus antibody, quantitative polymerase chain reaction (PCR for both HCV and hepatitis B virus (HBV, serum hyaluronic acid level, and alpha-fetoprotein (AFP. Fibroscan was performed on all HCV-positive patients. The mean age was 47.43 ± 12.65 years, 50.7% were male, and 49.3% were female. The most common causes of end-stage renal disease were hypertensive nephropathy (32.1% and diabetic nephropathy (18.7%. HCVAb was positive in 57.5% of the patients and HBV was positive in 3%. Forty HCV-positive patients (57.1% who underwent fibroscan had mild to significant fibrosis, and thirty patients (42.9% had advanced fibrosis. There was significant correlation between HCV PCR and duration on HD, number of blood transfusions, and hyaluronic acid (HA level. In addition, there was a significant correlation between serum HA and HD duration as well as liver fibrosis. No significant correlation was found between duration on HD and fibrosis stage (P = 0.619; also, no significant correlation was noted between the age of the patients and HA level or stage of fibrosis (P = 0.970. Fibro-scan is a simple noninvasive test that can be used to assess liver fibrosis in HD patients with CHC. Most of the study patients had mild to significant fibrosis.

    For regional and rural Queenslanders, chronic viral hepatitis treatment is a major unmet health need, with restricted access to specialists outside of tertiary, largely metropolitan hospitals. To increase treatment of chronic viral hepatitis in regional Queensland, a team-based telehealth model was expanded. This expansion embedded an initial nursing consultation prior to specialist telehealth consultation. We conducted a retrospective audit of the introduction and expansion of hepatology telehealth services. Activity from July 2014-June 2015 (pre-expansion) was compared with July 2015- June 2016 (post-expansion). Interviews were conducted with key staff to determine factors contributing to success of the service and identify ongoing challenges to the service model. A greater than four-fold increase in clinical consultation was observed (131 telehealth consultations pre-expansion vs 572 post-expansion; p Queensland. It may serve as a model to further expand telehealth management of chronic disease for regional Queenslanders. © The Author(s) 2016.

    Full Text Available Hepatitis B is one of the major diseases that affect the health of Chinese people, and chronic hepatitis B virus (HBV infection can lead to disease progression. Programmed death-1 (PD-1 discovered in recent years is an important coordinated stimulus molecule which belongs to the B7/CD28 family. After its binding with programmed death ligand (PD-L, it can regulate the activation, differentiation, and proliferation of T lymphocytes. PD-1 and its ligand are differently expressed in different stages of chronic HBV infection. The interaction between PD-1 and its ligand in different immune cells induces immune tolerance in human body and finally leads to the chronicity of HBV infection. Blocking the PD-1/PD-L signaling pathway through different ways can improve T cell exhaustion, suggesting that this might be one of the directions of antiviral therapy in future.

    Full Text Available Background: Conventional diagnostic procedures and therapy of acute liver failure (ALF and acute-on-chronic liver failure (ACLF focus on to identify triggering events of the acute deterioration of the liver function and to avoid them. Further objectives are to prevent the development respectively the progression of secondary organ dysfunctions or organ failure. Most of the times the endocrinological function of the liver can to a wide extent be compensated, but the removal of toxins can only marginally be substituted by conventional conservative therapy. To improve this component of the liver function is the main objective of extracorporal liver support systems. The following principles of liver support systems can be differentiated: Artificial systems, bioartifical systems and extracorporal liver perfusion systems. This HTA report focuses on artificial systems (e.g. BioLogic-DT/-DTPF, MARS, Prometheus, because only these approaches currently are relevant in the German health care system. In 2004 a category "Extracorporal liver assist device" was introduced in the list of "additional payments" in the German DRG-system, which makes reimbursement for hospitals using the technology in inpatient care possible, based on an hospital's individual contract with statutory sickness funds. Objectives: To report the present evidence and future research need on medical efficacy and economic effectiveness of extracorporal liver support devices for treatment of patients with ALF or ACLF based on published literature data. Are artificial liver support systems efficient and effective in the treatment of ALF or ACLF? Methods: An extensive, systematic literature search in medical, economic, and HTA literature data bases was performed. Relevant data were extracted and synthesised. Results: Relevant controlled trials were detected for BioLogic-DT and MARS. No randomised controlled trial on Prometheus was found. None of the included studies on BioLogic-DT showed

    Molecular epidemiologic studies reveal remarkable differences in the geographical distribution of hepatitis B virus (HBV) genotypes. The frequency of mutants among HBV genotypes also varies. The role of HBV genotypes/mutants in the pathogenesis of HBV infection and natural history of HBV infection has been extensively investigated. The distribution of HBV genotypes in acute hepatitis B patients reflects the predominant genotypes in a given geographic area. In chronic hepatitis B patients, genotype C and D have a higher frequency of basal core promoter A1762T/G1764A mutations than genotype A and B. HBV genotypes C, D and F carry a higher lifetime risk of cirrhosis and HCC development than genotype A and B. HBV pre-S/S gene mutations were associated with immune escape of hepatitis B immunoglobulin or vaccine-induced immunity. Mutations in the pre-S, core promoter and X regions correlate with an increased risk of cirrhosis and HCC. In summary, HBV genotypes and mutants are associated with the disease progression and long-term outcome of HBV infection. They may serve as viral genetic markers for risk stratification of chronic hepatitis B patients in clinical practice. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available This study was to evaluate the association between metabolic syndrome (MetS and chronic virus hepatitis elders in the community. Those subjects with positive hepatitis B surface antigen (HBsAg and/or anti-hepatitis C virus (anti-HCV screened in the community before were invited to this study and 451 responded. All participants underwent anthropometric measurements, blood tests, ultrasound and fibroscan examinations. The cut-off of liver stiffness measurement-liver cirrhosis (LSM-LC was 10 kPa for chronic hepatitis B (CHB patients and 12 kPa for chronic hepatitis C (CHC patients, respectively. Among 451 responders, 56 were excluded due to negative HBsAg or anti-HCV. Three hundreds and ninety-five subjects included 228 CHB patients, 156 CHC patients and 11 dual hepatitis patients, had a mean age of 62±12.6 years. Fifty-four (23.7% CHB patients coexisted with MetS whereas 40 (25.6% CHC patients also had MetS. Those patients with MetS had more LSM-LC cases than those without (20.4% vs 9.8%, p = 0.04 in CHB patients; 28.2% vs 13.5%, p = 0.037 in CHC patients, respectively. In multivariate logistic analysis, detectable viremia was reversely associated with MetS in CHB patients after adjustment for age, gender and body mass index (odds ratio (OR: 0.42; 95% confidence interval (CI: 0.18-0.99; p = 0.047. Regarding CHC patients, higher LSM level was the only factor contributed to MetS (OR: 1.1; 95% CI: 1.02-1.19; p = 0.012. In conclusion, elder CHB patients coexisted with MetS might experience an inactive virus replication but have an advanced liver fibrosis. In elder CHC patients, only higher LSM level was associated with MetS.

    Severe acute hepatotoxicity is a well known complication following the ingestion of ecstasy (3,4-methylenedioxymethamphetamine [MDMA] ecstasy). Hepatic dysfunction has also been reported after acute cocaine intoxication. However, chronic hepatitis after prolonged use of ecstasy and/or cocaine has rarely been reported. We report the case of a 27-year-old woman hospitalized with edema, ascites and severe liver failure (prothrombin rate 33%), following the use of ecstasy and cocaine over the previous 9 months. Clinical, biological, radiological and pathology findings were recorded at admission and over 8 years' follow-up. Liver biopsy showed architectural distortion caused by bridging fibrosis, proliferation of cholangioles, and lesions of active interface hepatitis. Other causes of acute and chronic liver disease were excluded. Magnetic resonance imaging showed marked liver fibrosis. After withdrawal of both substances clinical examination and liver function tests progressively normalized. Long-term monitoring with magnetic resonance imaging showed progressive regression of fibrosis. Use of ecstasy and cocaine may cause chronic hepatitis leading to marked liver fibrosis, which may regress after withdrawal of both substances. Copyright © 2013 Elsevier Masson SAS.

  1. Treatment of type 2 diabetes mellitus by viral eradication in chronic hepatitis C: Myth or reality?

    Science.gov (United States)

    Vanni, Ester; Bugianesi, Elisabetta; Saracco, Giorgio

    2016-02-01

    Chronic hepatitis C is a systemic disease inducing metabolic alterations leading to extrahepatic consequences. In particular, hepatitis C virus (HCV) infection seems to increase the risk of incident type 2 diabetes mellitus in predisposed individuals, independently of liver disease stage. The mechanisms through which hepatitis C induces T2DM involve direct viral effects, insulin resistance, pro-inflammatory cytokines and other immune-mediated processes. Many studies have reported the clinical consequences of type 2 diabetes mellitus on hepatitis C outcome, but very few studies have addressed the issue of microangiopathic complications among patients with hepatitis C only, who develop type 2 diabetes mellitus. Moreover, clinical trials in HCV-positive patients have reported improvement in glucose metabolism after antiviral treatment; recent studies have suggested that this metabolic amelioration might have a clinical impact on type 2 diabetes mellitus-related complications. These observations raise the question as to whether the HCV eradication may also have an impact on the future morbidity and mortality due to type 2 diabetes mellitus. The scope of this review is to summarise the current evidence linking successful antiviral treatment and the prevention of type 2 diabetes mellitus and its complications in hepatitis C-infected patients.

    Full Text Available Prevalence of hepatitis C varies largely according to geographical distribution, and Egypt so far has the highest prevalence worldwide. The aim of this study was to evaluate hepatitis C infection in chronic kidney disease (CKD children in our center with regard to its incidence and other morbidities. This is a cross-sectional study involving 50 children with CKD, not on dialysis. All patients underwent a thorough history taking including disease duration and mean duration of admission, clinical examination including blood pressure measurements, and routine laboratory examination such as hemoglobin level, serum aspartate aminotransferase (AST, alanine aminotransferase (ALT, urea, and creatinine. The detection of anti-hepatitis C virus (HCV antibodies was done in all patients based on the use of third-generation enzyme immunoassay (EIA that detects antibodies directed against various HCV epitopes. Nine (18% children were found to be hepatitis C positive and 41 were negative to hepatitis C. Infected cases were of older age group and had a longer duration of CKD, lower estimated glomerular filtration rate (eGFR, lower hemoglobin, higher ALT, higher serum urea, and creatinine. We conclude that 18% of children with CKDs have hepatitis C infection, and those with longer the duration of renal disease is more likely to be positive for HCV. Furthermore, HCV infection may predispose to higher deterioration of eGFR, lower hemoglobin level, and more days of admission. We recommend routine testing of HCV in all children with CKD.

    Full Text Available Molecular biology techniques are routinely used nowadays to diagnose and evaluate antiviral treatment of patients with chronic hepatitis B (HBV and hepatitis C virus (HCV infections. Current tools at our disposal include tests that quantify the amount of circulating virus in the blood, techniques that can analyse genomic sequences to determine viral genotypes or subtypes, or determine amino-acid substitutions that may confer resistance to existing antiviral drugs. What is more, continuously evolving serological tests for the detection of viral antigens or their corresponding antibodies, have made diagnosis of disease as sensitive as possible. The present review will concentrate primarily on molecular diagnostics.

    Braga Eduardo Lorens

    Full Text Available Co-infection with hepatitis C virus (HCV and human immunodeficiency virus (HIV is increasingly common and affects the clinical course of chronic hepatitis C. Highly active antiretroviral therapy has improved the life expectancy of HIV infected patients, but, by extending survival, it permits the development of HCV cirrhosis. This study tried to evaluate clinical and epidemiological features of patients with chronic hepatitis C co-infected with HIV. We evaluated 134 HCV-infected patients: i group A - 65 co-infected HCV/HIV patients, ii group B - 69 mono-infected HCV patients. The impact of HIV infection on HCV liver disease was analyzed using Child's score, ultrasound findings and liver histology. Patients were subjected to HCV genotyping and anti-HBs dosage. Patients mean age was 42.4 years (±9.1 and 97 (72.4% were males. Injected drug use and homo/bisexual practice were more frequently encountered in the co-infected group: 68.3% and 78.0%, respectively. Antibodies against hepatitis B virus (anti-HBs were found in only 38.1% of the patients (66.7% group A x 33.3% group B. Ten out of 14 individuals (71.4% who had liver disease (Child B or C and 25 out of 34 (73.5% who showed ultrasound evidence of chronic liver disease were in the co-infection group. HCV genotype-2/3 was more frequently encountered in co-infected patients (36.9% group A vs. 21.8% group B. Conclusions: a HIV infection seems to adversely affect the clinical course of chronic hepatitis C, b injected drug use, bi/homosexual practice and genotype-2/3 were more frequently encountered in co-infected patients, c immunization against HBV should be encouraged in these patients.

    Objective: To study the abnormal findings and metabolic alterations of the brain in chronic hepatic disease with MRI and 1 H magnetic resonance spectroscopy ( 1 H-MRS) for better understanding the clinical significance of pallidal hyperintensity and the role in the diagnosis and treatment of hepatic encephalopathy (HE). Methods: Brain MRI and 1 H-MRS examination were performed in 50 patients with chronic hepatic disease and 20 healthy volunteers. The pallidus index (PI) was calculated and the height of resonance peaks of Glx was measured. The correlation between PI and Child/Pugh classification, and the association between blood ammonia and the spectroscopic alterations were studied. Pre-and post-therapeutic comparative study was also conducted in 5 cases with chronic HE. Results: PI was gradually increased from healthy volunteers to patients with chronic hepatitis and liver cirrhosis (1.01± 0.04, 1.06±0.09, and 1.18±0.09), and the differences in PI value among them were significant (F=22.294, P 1 -weighted MRI disappeared and the abnormal metabolic alterations returned to normal range 5 to 6 months after successful liver transplantation. However, the normalization of 1 H-MRS alterations preceded the disappearance of pallidal hyperintensities. Conclusion: PI can be an index of reference for liver dysfunction. Glx is more sensitive than blood ammonia in detecting the brain dysfunction. MRI and 1 H-MRS are reliable techniques in the diagnosis and evaluation of therapy for hepatic encephalopathy. (authors)

    Conclusion: In chronic carriers who already had HBsAg variants selected by the host-immune response, any immune stimulation by the vaccine had no effect on the chronic state of these patients or selected any remarkable escape mutants. Newer strategies should be considered based on third generation or the use of DNA vaccines or new adjuvants.

    Full Text Available Gallbladder (GB stones have been associated with several metabolic factors and liver diseases. This community-based study aimed at investigating the prevalence rate of GB stones and its associated factors in a hepatitis B virus (HBV/hepatitis C virus (HCV-endemic township in southern Taiwan. A total of 1701 residents (689 males and 1012 females; mean age: 51.2 ± 16.0 years were enrolled in this prospectively designed screening project. Serum biochemistry tests, including testing for levels of serum aspartate aminotransferase, alanine aminotransferase (ALT, hepatitis B surface antigen (HBsAg, and antibody to HCV (anti-HCV were conducted. In addition, a hepatobiliary ultrasonographic (US examination was also conducted. Of the 1701 residents, 243 (14.3% and 475 (27.9% were found to be positive for HBsAg and anti-HCV, respectively. Results of the US examination revealed the prevalence rate of GB stone and fatty liver to be 6.8% and 55.6%, respectively. Using univariate analyses we found that significantly higher proportions of the participants with GB stone were male, over 50 years of age, positive for anti-HCV (p = 0.001, p 50 year were identified as independent factors associated with the formation of GB stones. Anti-HCV was associated with GB stones in males but not in females in both univariate and multivariate analyses. GB stones were found to have a prevalence rate of 6.8% in this HCV/HBV hyperendemic township and are associated with higher mean age. A correlation between chronic hepatitis C and GB stones is observed only among males.

    Full Text Available Blood markers of endothelial activation (sVCAM-1, vWF: Ag in patients with chronic hepatitis C in the presence of insulin resistance, metabolic syndrome and its components had been evaluated. The study included 69 patients with chronic hepatitis C with oligosymptomatic the disease. In one third of cases of chronic hepatitis C (33.3% showed improvement in the blood content of sVCAM-1 and / or vWF: Ag. In patients with chronic hepatitis C with insulin resistance, metabolic syndrome significantly more often found signs adhesion of endothelial dysfunction (increased blood concentrations of sVCAM-1 than in patients without these disorders. Found that in patients with severe hepatic fibrosis in patients with chronic hepatitis C blood concentration sVCAM-1 is significantly higher compared to patients with early stages of fibrosis (F0-F2, including those in patients without insulin resistance. These data suggest the multivariate development of endothelial dysfunction in chronic hepatitis C.

    To compare several noninvasive indices of fibrosis in chronic viral hepatitis B, including liver shear-wave velocity (SWV), hyaluronic acid (HA), collagen type IV (CIV), procollagen type III (PCIII), and laminin (LN). Acoustic radiation force impulse (ARFI) was performed in 157 patients with chronic viral hepatitis B and in 30 healthy volunteers to measure hepatic SWV (m/s) in a prospective study. Serum markers were acquired on the morning of the same day of the ARFI evaluation. Receiver operating characteristic (ROC) analysis was performed to evaluate and compare the accuracies of SWV and serum markers using METAVIR scoring from liver biopsy as a reference standard. The most accurate test for diagnosing fibrosis F ≥ 1 was SWV with the area under the ROC curve (AUC) of 0.913, followed by LN (0.744), HA (0.701), CIV (0.690), and PCIII (0.524). The best test for diagnosing F ≥ 2 was SWV (AUC of 0.851), followed by CIV (0.671), HA (0.668), LN (0.562), and PCIII (0.550). The best test for diagnosing F ≥ 3 was SWV (0.854), followed by CIV (0.693), HA (0.675), PCIII (0.591), and LN (0.548). The best test for diagnosing F = 4 was SWV (0.965), followed by CIV (0.804), PCIII (0.752), HA (0.744), and LN (0.662). SWV combined with HA and CIV did not improve diagnostic accuracy (AUC = 0.931 for F ≥ 1, 0.863 for F ≥ 2, 0.855 for F ≥ 3, 0.960 for F = 4). The performance of SWV in diagnosing liver fibrosis is superior to that of serum markers. However, the combination of SWV, HA, and CIV does not increase the accuracy of diagnosing liver fibrosis and cirrhosis.

    Interferon α (IFN-alpha) is widely used in the treatment of viral infections, including hepatitis C. Unfortunately depression is a common side effect of IFN-alpha therapy. The presence of depressive symptoms is important because they have an adverse effect on the course of the illness and reduce the quality of life and the treatment adherence. The current prospective study examines the effects of IFN-alpha on the development of depressive disorders, on cognitive functioning and on quality of life. A total of 25 patients with chronic hepatitis C infection were investigated. All patients were treated in the Department of Gastroenterology and Hepatology, University of Medicine of Graz, Austria. Psychometric observer rating and self-rating scales were administered 1 month and 3 months after the beginning of the antiviral treatment to evaluate depressive symptoms [Beck Depression Inventory (BDI); Hamilton Depression Scale]. The data on life satisfaction before therapy and health-related quality of life were obtained from the Fragebogen zur Lebenszufriedenheit (FLZ) and the SF-36 (Health Status Questionnaire). Cognitive function was based on the SKT (Syndrom Kurztest). All patients completed the Social Support Questionnaire (SSS), a multidimensional self-report measure of social support. Three months after the initial IFN-alpha administration in the whole sample significant impairments in health-related quality of life were found in the health-related domains "physical functioning", "role physical", "role emotional", "social functioning" and "vitality". The whole sample showed cognitive impairments. No changes in social support were recorded. Three months after the first INF-alpha administration, 48% (n=12) of the sample suffered from moderate clinical depression. In comparison to patients without pathological affective findings, patients with INF-alpha-induced clinical depression showed decreased life satisfaction before the initial antiviral therapy.

    Based on genetic analysis of variants obtained around the world, three genotypes of the hepatitis delta virus have been defined. Hepatitis delta virus variants have been associated with different disease patterns and geographic distributions. To determine the prevalence of hepatitis delta virus genotypes in the northeast of Spain (Catalonia) and the correlation with transmission routes and clinical disease, we studied the nucleotide divergence of the consensus sequence of HDV RNA obtained from 33 patients with chronic delta hepatitis (24 were intravenous drug users and nine had no risk factors), and four patients with acute self-limited delta infection. Serum HDV RNA was amplified by the polymerase chain reaction technique and a fragment of 350 nucleotides (nt 910 to 1259) was directly sequenced. Genetic analysis of the nucleotide consensus sequence obtained showed a high degree of conservation among sequences (93% of mean). Comparison of these sequences with those derived from different geographic areas and pertaining to genotypes I, II and III, showed a mean sequence identity of 92% with genotype I, 73% with genotype II and 61% with genotype III. At the amino acid level (aa 115 to 214), the mean identity was 87% with genotype I, 63% with genotype II and 56% with genotype III. Conserved regions included the RNA editing domain, the carboxyl terminal 19 amino acids of the hepatitis delta antigen and the polyadenylation signal of the viral mRNA. Hepatitis delta virus isolates in the northeast of Spain are exclusively genotype I, independently of the transmission route and the type of infection. No hepatitis delta virus subgenotypes were found, suggesting that the origin of hepatitis delta virus infection in our geographical area is homogeneous.

    Full Text Available The hospitalized cases and mortality from alcoholic liver disease (ALD are increasing in Taiwan and worldwide. Meanwhile, the Asia–Pacific region also has a high prevalence of hepatitis B virus (HBV and hepatocellular carcinoma (HCC. The Taiwanese have the highest percentage of aldehyde dehydrogenase 2 (ALDH2 deficiency and the lowest amount of alcohol consumption. Based on the histological changes, ALD is clinically classified as steatosis, alcoholic hepatitis, alcoholic fibrosis, alcoholic cirrhosis, and alcoholic hepatitis on cirrhosis. Patients with overt alcoholic hepatitis often develop marked hepatomegaly, audible hepatic arterial bruit, mild leukocytosis, and mild fever. Patients having alcoholic cirrhosis had much more serious complications and mortality. It is clinically important to identify hepatic fibrosis and cirrhosis earlier for early management. Active assessments for esophageal varices and ascites may help the diagnosis of cirrhosis. Sonography is helpful for exanimating features of cirrhosis including portal hypertension, ascites, increased hepatic portal flow, and collaterals. Synergistic damage of viral hepatitis on ALD patients lead to rapid progression to cirrhosis and HCC. Distinct from the Western population, 30% of Taiwanese alcoholics had concomitant chronic HBV regardless of the different histologic categories. Patient groups with combined alcoholics and HBV had fewer platelet counts and much more cirrhosis with Ishak Stage 5–6 fibrosis. The annual incidences of HCC were significantly higher in alcoholic cirrhotic patients having concomitant HBV infection than those with only HBV infection or alcoholism alone. Antiviral nucleotide and nucleoside analogs therapy reduces the prevalence of HCC to a similar level to those ALD patients without active HBV.

    Chronic hepatitis C virus (HCV) infection has been suggested to be associated with non-insulin-dependent diabetes mellitus and lipid profiles. This study aimed to investigate the possible relationships of insulin resistance (IR) and lipid profiles with chronic hepatitis C (CHC) patients in Taiwan. We enrolled 160 hospital-based CHC patients with liver biopsy and the 480 controlled individuals without CHC and chronic hepatitis B from communities without known history of non-insulin-dependent diabetes mellitus. Fasting plasma glucose, total cholesterol, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triglycerides (TGs), alanine aminotransferase, and serum insulin levels, and homeostasis model assessment (HOMA-IR) were tested. When comparing factors between CHC patients, and sex- and age-matched controls who had no HCV infection, patients with HCV infection had a significantly higher alanine aminotransferase level, fasting plasma glucose level, insulin level, and HOMA-IR (P C and LDL-C levels (all P  2.5]), a high body mass index, TGs, and HCV RNA level are independent factors significantly associated with high HOMA-IR in multivariate logistic analyses. Chronic HCV infection was associated with metabolic characteristics including IR and lipid profile. IR was also associated with virological characteristics. © 2013 Journal of Gastroenterology and Hepatology Foundation and Wiley Publishing Asia Pty Ltd.

    Full Text Available ABSTRACT BACKGROUND Vitamin D is known for its immunomodulatory, anti-inflammatory and antifibrotic properties, which are quite relevant in the pathogenesis and treatment of many causes of chronic liver disease. OBJECTIVE This study aimed to evaluate the association between serum vitamin D levels and the histopathological findings in patients with chronic hepatitis C virus infection. METHODS Cross-sectional study composed of patients with chronic hepatitis C. All patients underwent vitamin D 25 dosage and anthropometric data analysis. Liver biopsy was performed in a maximum 36-month period before inclusion in the study. RESULTS Of the 74 patients included in the study, 45 (60.8% were women, mean age was 57.03±9.24 years, and 63 (85.1% were white. No association was observed between the serum levels of vitamin D and inflammatory activity (P=0.699 nor with the degree of liver fibrosis (P=0.269. CONCLUSION In this study, no association was observed between vitamin D and inflammatory activity, as well as the degree of liver fibrosis, in patients with chronic hepatitis C.

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

    Disclosure is a prerequisite to receive disease-specific social support. However, in the case of a stigmatised disease, it can also lead to discrimination. We aimed to assess disclosure rates of HIV patients and the reactions they encountered in comparison to patients with chronic viral hepatitis or diabetes mellitus and patients' general perception of disease-specific discrimination. We constructed a self-report questionnaire, anonymously assessing the size of the social environment, the persons who had been informed, and the experienced reactions as perceived by the disclosing patients, to be rated on 1-4 point Likert scales. In addition, patients were asked whether they perceive general discrimination in Germany. One hundred and seventy-one patients were asked to participate. Five rejected, thus questionnaires from 83 patients with HIV, 42 patients with chronic viral hepatitis B (n = 9) or C (n = 33), and 41 patients with insulin-dependent diabetes mellitus (type I n = 14, type II n = 27) were analysed. Whereas the size of the social environment did not differ, HIV-infected patients were least likely to disclose their disease (60.7%, SD ± 31.9) to their social environment as compared to patients with chronic viral hepatitis (84.2 ± 23.3%, pdiabetes mellitus (94.4 ± 10.3%, ppatient group, the mean disclosure rate was highest to partners (90.9%), followed by the public environment (65.2%), friends (59.4%) and family members (43.8%). HIV patients experienced supportive reactions after 79.3 ± 26.4% of disclosures, which was the case in 91.4 ± 19.6% and 75.7 ± 36.1% of patients with hepatitis or diabetes mellitus, respectively. 69.5% of HIV patients stated to perceive general discrimination in Germany. We conclude that HIV patients had experienced supportive reactions after the majority of disclosures, but the low rate points out that their information strategy had been very selective. Societal discrimination of HIV patients is still an issue and needs to be

    Over the past decade,significant improvements have been made in the treatment of chronic hepatitis C(CHC),especially with the introduction of combined therapy using both interferon and ribavarin.The optimal dose and duration of treatment is still a matter of debate and,importantly,the efficacy of this combined treatment varies with the viral genotype responsible for infection.In general,patients infected with viral genotypes 2 or 3 more readily achieve a sustained viral response than those infected with viral genotype 1.The introduction of a pegylated version of interferon in the past decade has produced better clinical outcomes in patients infected with viral genotype 1.However,the published literature shows no improvement in clinical outcomes in patients infected with viral genotypes 2 or 3 when they are treated with pegylated interferon as opposed to nonpegylated interferon,both given in combination with ribavarin.This is significant because the cost of a 24-wk treatment with pegylated interferon in lessdeveloped countries is between six and 30 times greater than that of treatment with interferon.Thus,clinicians need to carefully consider the cost-versusbenefit of using pegylated interferon to treat CHC,particularly when there is no evidence for clinically measurable benefits in patients with genotypes 2 and 3 infections.

    Full Text Available Abstract Background Hepatitis C virus (HCV is a major cause of chronic hepatitis and hepatocellular carcinoma (HCC and different HCV genotypes show characteristic variations in their pathological properties. Insulin resistance (IR occurs early in HCV infection and may synergize with viral hepatitis in HCC development. Egypt has the highest reported rates of HCV infection (predominantly genotype 4 in the world; this study investigated effects of HCV genotype-4 (HCV-4 on prevalence of insulin resistance in chronic hepatitis C (CHC and HCC in Egyptian patients. Methods Fifty CHC patients, 50 HCC patients and 20 normal subjects were studied. IR was estimated using HOMA-IR index and HCV-4 load determined using real-time polymerase chain reaction. Hepatitis B virus was excluded by enzyme-linked immunosorbent assay. Standard laboratory and histopathological investigations were undertaken to characterize liver function and for grading and staging of CHC; HCC staging was undertaken using intraoperative samples. Results HCC patients showed higher IR frequency but without significant difference from CHC (52% vs 40%, p = 0.23. Multivariate logistic regression analysis showed HOMA-IR index and International Normalization Ratio independently associated with fibrosis in CHC; in HCC, HbA1c, cholesterol and bilirubin were independently associated with fibrosis. Fasting insulin and cholesterol levels were independently associated with obesity in both CHC and HCC groups. Moderate and high viral load was associated with high HOMA-IR in CHC and HCC (p Conclusions IR is induced by HCV-4 irrespective of severity of liver disease. IR starts early in infection and facilitates progression of hepatic fibrosis and HCC development.

    In order to analysis the fibrosis stage and inflammatory activity grade of chronic hepatitis C, a novel classification method based on collaborative representation (CR) with smoothly clipped absolute deviation penalty (SCAD) penalty term, called CR-SCAD classifier, is proposed for pattern recognition. After that, an auto-grading system based on CR-SCAD classifier is introduced for the prediction of fibrosis stage and inflammatory activity grade of chronic hepatitis C. The proposed method has been tested on 123 clinical cases of chronic hepatitis C based on serological indexes. Experimental results show that the performance of the proposed method outperforms the state-of-the-art baselines for the classification of fibrosis stage and inflammatory activity grade of chronic hepatitis C.

    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

    Full Text Available Background. The problem of viral hepatitis C in the modern world is rather acute for public health service. The patients themselves, their striving for recovery, desire to have the quality of live on the same level as a healthy person has and the understanding of the necessity to obey the a doctor’s recommendations play the significant role in the successful treatment of this disease. The aim of the given work is the study of the quality of life and the adherence to treatment of young people with chronic viral hepatitis C and the following analysis of the results. Materials and methods. In the process of research, 138 men at the age of 18–45 with chronic viral hepatitis were ex- amined. The verification of the diagnosis occurred on the basis of international classification of chronic hepatitis (Los Angeles, 1994, and also ICD10 (B17.1, besides, the HCV RNA for more than 6 months was also taken into account. Twenty-five apparently healthy men 18–45 years old were included in this group. The quality of life was clarified with the help of short form of the adapted Russified specialized questionnaire “Medical Outcomes Study, Short Form” (SF36 Health Study Survey. Statistical data processing was carried out with the use of application package “Statistica for Windows”, version 7.0. Results. The minimum index in the group of the patients with chronical viral hepatitis C was the index of social activity (SF – 46.2 ± 0.8 points. In this group, the index of physical pain (BP was at its maximum. The study of the adherence to treatment depending on the quality of life stays acute. Conclusions. During the course of this work, the peculiarities of the quality of life scales were determined according to the SF-36 Health Study Survey among the patients with chronic viral hepatitis C and the correlations with the adher- ence to treatment.

    Paraoxonase (PON), a high density lipoprotein (HDL) associated enzyme, is believed to protect against the oxidation of low density lipoprotein (LDL) and hence affects the risk of vascular disease. PON is sensitive to oxidants and is inactivated by oxidized lipids, and thus it can be postulated that increased oxidative stress may decrease plasma PON activity in patients with chronic renal failure (CRF) and hepatic insufficiency (HI). Moreover, in CRF and HI patients, in contrast to normal individuals, higher levels of plasma biochemical parameters and liver enzymes had an inverse correlation with PON activity. In this study we aimed to investigate PON activity, total bilirubin, creatinine, urea and liver enzymes alanine aminotransferase and alkaline phosphatase that are the index of renal and hepatic insufficiency. We have analyzed plasma from pre-dialysis patients and compared the results with the normal individuals. We observed a positive association of PON activity with that of the disease state i.e. the activity of this enzyme was significantly lower in the patients (p < 0.001). Furthermore, the indicators of renal and hepatic insufficiency were significantly elevated as compared to the normal subjects. Based on our results we conclude that in CRF and HI, in contrast to normal individuals, higher levels of plasma biochemical parameters and liver enzymes had inverse correlation with PON activity. Collectively, these findings may add details to the understanding of the role that PON plays in chronic renal failure and hepatic insufficiency. (author)

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

    Hepatic steatosis occurs in 40-70% of patients chronically infected with hepatitis C virus [chronic hepatitis C (CH-C)]. Hepatic steatosis in CH-C is associated with progressive liver disease and a low response rate to antiviral therapy. Gene expression profiles were examined in CH-C patients with and without hepatic steatosis, non-alcoholic steatohepatitis (NASH) and fibrosis. This study included 65 CH-C patients who were not receiving antiviral treatment. Total RNA was extracted from peripheral blood mononuclear cells, quantified and used for one-step reverse transcriptase-polymerase chain reaction to profile 153 mRNAs that were normalized with six 'housekeeping' genes and a reference RNA. Multiple regression and stepwise selection assessed differences in gene expression and the models' performances were evaluated. Models predicting the grade of hepatic steatosis in patients with CH-C genotype 3 involved two genes: SOCS1 and IFITM1, which progressively changed their expression level with the increasing grade of steatosis. On the other hand, models predicting hepatic steatosis in non-genotype 3 patients highlighted MIP-1 cytokine encoding genes: CCL3 and CCL4 as well as IFNAR and PRKRIR. Expression levels of PRKRIR and SMAD3 differentiated patients with and without superimposed NASH only in the non-genotype 3 cohort (area under the receiver operating characteristic curve=0.822, P-value 0.006]. Gene expression signatures related to hepatic fibrosis were not genotype specific. Gene expression might predict moderate to severe hepatic steatosis, NASH and fibrosis in patients with CH-C, providing potential insights into the pathogenesis of hepatic steatosis and fibrosis in these patients.

    Full Text Available Background. The prognostic importance of α-fetoprotein (AFP level elevation in patients with chronic hepatitis C and its clinical significance in steatosis associated with HCV infection remain to be determined. The present paper assessed clinical significance of elevated AFP in patients with CHC with and without steatosis. Methods. One hundred patients with CHC were divided into 50 patients with CHC and steatosis and 50 patients with CHC and no steatosis based on liver biopsy. Results. AFP was significantly increased in CHC with steatosis than patients without steatosis (P<0.001. Highly significant positive correlation was found between serum AFP and necroinflammation as well as the severity of fibrosis/cirrhosis and negative significant correlation with albumin level in chronic HCV with steatosis (P<0.001 but negative nonsignificant correlation with ALT and AST level (P≤0.778 and 0.398, respectively. Highly significant increase was found in chronic hepatitis patients with steatosis than CHC without steatosis regarding necroinflammation as well as the severity of fibrosis/cirrhosis and AFP (P<0.001. Conclusion. Patients with chronic HCV and steatosis have a higher AFP levels than those without steatosis. In chronic HCV with steatosis, elevated AFP levels correlated positively with HAI and negative significant correlation with albumin level.

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

    The current treatment recommendation for chronic hepatitis C virus infection is the combination of peginterferon and ribavirin for 24 or 48 weeks, depending on the viral genotype. The aim of the therapy is to obtain a sustained virological response. To report our experience in the treatment of chronic hepatitis C. Analysis of 52 patients treated between September 2000 and June 2009. Patients with genotype 1 or 5 were treated with peginterferon alpha 2a (180 ug/week) and ribavirin (1000 mg/day for those weighing less than 75 kg and 1200 mg/day for those weighing more than 75 kg) during 48 weeks. Patients with genotypes 2 and 3 were treated for 24 weeks with the same dose of peginterferon and ribavirin 800 mg/day. Viral genotypes 1, 2, 3 and 5 were present in 81, 4, 11 and 4% of patients, respectively. Twenty four patients (46 %), 18 with genotype 1, achieved a sustained viral response. Age was the only variable that influenced the response to treatment. Approximately half of the patients with chronic hepatitis C, achieve a sustained viral response with peginterferon and ribavirin.

    Non-organ-specific autoantibodies (NOSAs) are frequently found in the sera of patients with Hepatitis C Virus (HCV) infection. However, no conclusive answers have been produced concerning the clinical relevance of these antibodies. To determine whether a relationship might exist between the presence of NOSA and the severity of liver disease in chronic hepatitis C. 186 treatment-naïve chronic hepatitis C patients were studied consecutively for autoantibodies. Liver biopsies were analyzed according to the Metavir score. NOSAs were present in 75 patients (40%). Anti-nuclear antibodies were found in 32% of patients (speckled pattern), anti-smooth muscle in 15% without F-actin specificity, anti-mitochondria in 0.5%, and anti-LKM1 in 0.5%, respectively. No liver-cytosol1 or soluble liver antigen antibodies were detected. There was a highly significant correlation between the positivity of NOSA and the degree of inflammation and hepatocellular injury (p = 0.001) and also with the degree of fibrosis (p < 0.0001). The presence of NOSA was associated with higher aspartate aminotransferase, gamma-glutamyl-transpeptidase, gamma-globulin and immunoglobulin G levels. By contrast, no differences were observed regarding age, gender, route of infection, duration of disease, HCV genotypes or viral load. NOSAs were associated with the most severe forms of chronic HCV infections.

    Full Text Available Abstract Background Hepatitis B and C are silent killers not yet recognized as major public health challenges in many developing countries with huge disease burden. In Ethiopia, Hepatitis B is endemic with an average prevalence of 10.8 %, and the prevalence of Hepatitis C is 2 %. The prevalence of both infections, however, is likely to be underreported due to the lack of diagnostic facilities and appropriate surveillance systems. Ethiopia is also among the many Sub-Sahara African countries lacking a coordinated and systematic national response to chronic viral hepatitis. The objective of this study is to examine the current level of response to viral Hepatitis B & C in Ethiopia with the aim to bring identified gaps to the attention of relevant stakeholders and policy makers. Methods This cross-sectional qualitative study was based on semi-structured in-depth interviews with 21 key informants from health facilities, health offices, pharmaceutical companies, regulatory bodies, professional association and blood bank units. Participants were selected purposively based on their role in the national hepatitis response. The investigators also reviewed available policy and strategy documents, standards of practice and surveys, and paid visits to pharmaceutical premises to check the availability of antiviral drugs. Thematic analysis was employed to make sense of the data. During the data analysis process, all the authors critically read the materials, and data was triangulated by source, interpreter view and thematic perspective to ensure accurate representation and comprehensiveness, and validation of the interviewees’ responses. Once each investigator reviewed the data independently, the team reached a common understanding of the scope and contexts of the information attained.

    Despite the availability of a safe and efficacious vaccine, new cases of infection by hepatitis B virus (HBV) still occur at a substantial rate. This increases the current prevalence of chronic HBV carriers (10% of newly infected subjects) and in the long run, will raise the incidence of chronic liver disease. The surveillance of viral hepatitis commenced in December 1990 by the French sentinel network for electronic surveillance of communicable diseases. Between 1991 and 1996, a decrease in the annual incidence was observed although it was not significant (p=0.06). The mean number of cases for this period was 12 per 100,000 inhabitants. The sex ratio (M/F) was 1.6 (p<0.01) and the median age, 32 years. Heterosexual transmission was suspected in 25% of cases, homo- bisexual transmission in 10%, use of injected drugs in 19%, percutaneous exposure in 9%, and blood transfusion or hemodialysis in 6%. Although the incidence of HBV infection is decreasing, the prevalence of chronic infection will continue to rise. However, the universal hepatitis B immunisation strategy proposed by WHO will dramatically limit the expansion of the population of chronically infected subjects if high coverage is achieved rapidly

    Aim: To evaluate liver necro-inflammation and function by using gadoxetic acid-enhanced dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI), with histological analysis as the reference standard. Materials and methods: Seventy-nine subjects (21 healthy subjects; 58 chronic hepatitis patients) who received gadoxetic acid-enhanced DCE-MRI were divided into three subgroups: no (A0, n = 31), mild (A1, n = 27), and moderate–severe (A2–A3, n = 21) activities. Two DCE-MRI models were measured: (1) a dual-input single-compartment model to obtain absolute arterial, portal venous, and total blood flow, arterial fraction (ART), distribution volume, and mean transit time; (2) a curve analysis method to obtain peak, slope, and AUC (area under curve). The serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels also obtained. Statistical testing included Kruskal–Wallis tests for continuous data, Pearson's correlation tests, and multiple linear regression analyses. Results: Hepatic necro-inflammatory activity grades were significantly correlated with fibrotic stages, serum ALT level, ART and AUC. ART was helpful to predict the mild activity (≤A1 versus >A1; Az = 0.728), whereas AUC could differentiate no activity from any activity (A0 versus >A0; Az = 0.703). Peak, slope and AUC were all associated with AST and ALT (p < 0.05). Conclusion: Gadoxetic acid-enhanced DCE-MRI parameters may be used to evaluate the severity of hepatic necro-inflammation and function

    Full Text Available Introduction: High risk of blood-borne infections is one of the problems of patients with chronic kidney disease (CKD, above which, there is hepatitis B. One of the ways to prevent this disease is vaccination against hepatitis B besides observing standard precautions. Lack of response to vaccine in uremic patients has been reported up to 33.0%. The aim of this study was to investigate the effect of levamisole as an adjuvant in improving vaccination response in patients suffering from CKD. Methods: In this cohort study, 30 patients suffering from the chronic renal disease who had undergone levamisole plus hepatitis B vaccine were included in the study as exposed group (Group A. Then 30 equivalent patients who had just underwent hepatitis B vaccination were in the study as a unexposed group (Group B. Antibody titer against hepatitis B virus (HBV was compared between two groups monthly, then data was analyzed. Results: Mean age of all investigated patients was 58.1 ± 14.9 years old, and it ranged from 26 to 82. 23 patients (38.3% were female, and 37 patients (61.7% were male. None of the patients in both groups had a history of previous hepatitis B vaccination. Mean antibody titer was higher in group A than that of the group B after the first and second stages of hepatitis B vaccination. However, the difference between two groups was not statistically significant (P = 0.14 and P = 0.46 respectively. Also, the mean antibody titer after the third stage was 98.8 ± 61 u/l in group A and 86.2 ± 49 u/l in group B where the difference between two groups was not statistically significant (P = 0.38. Side effects resulted from levamisole was not observed in any of patients in group A. Conclusion: According to the results it is possible to express that levamisole pill could be used as a proper adjuvant in improving the response of hepatitis B vaccination in patients suffering from CKD. However, further studies in this field are recommended according to the

    Full Text Available Objective: the hepatocyte growth factor (HGF is a pleiotropic cytokine produced by hepatic stellate cells and implicated in liver regeneration and fibrosis. Serum levels of HGF vary in liver diseases, reflecting hepatic damage and hepatocellular dysfunction. In this study, serum levels of HGF and the relationship between HGF and biochemical, histological and virological data, have been analysed in patients suffering from chronic hepatitis C (CHC. Patients and methods: serum HGF concentration was measured by ELISA in sandwich in 45 patients with CHC. Correlation between HGF levels and histological (necroinflammatory activity and fibrosis score and biochemical (transaminases, prothrombin activity, albumin, bilirubin, or virological (hepatitis C virus load parameters was analyzed. Serum HGF concentration was also studied in a subgroup of the original sample treated with interferon and ribavirin. Results: serum HGF concentrations of patients with CHC were significantly higher than those detected in healthy controls.

    Hepatitis A virus (HAV) superinfection is associated with a high risk of liver failure and death in patients with hepatitis C virus (HCV) infection. The aim of this study was to investigate the presence of serological and molecular HAV markers in a population of HCV-infected patients in order to determine a cost-effective strategy to vaccinate against HAV. The presence of total and immunoglobulin (Ig)M anti-HAV antibodies was investigated in 399 patients (median age, 50 years; range, 4-81) referred to the Public Health Central Laboratory of Pernambuco State who tested positive for anti-HCV antibodies and HCV RNA. HAV RNA was investigated by reverse transcription-nested polymerase chain reaction in these patients. Three hundred and eighty-four (96%) patients were positive for anti-HAV total and negative for IgM anti-HAV antibodies (immune patients). Three patients had IgM (and total) anti-HAV antibodies, showing an acute infection, and two of them had HAV RNA detected in serum samples. HAV RNA was also found in another patient in the absence of detectable anti-HAV antibodies. By nucleotide sequencing, it was demonstrated that the HAV isolates infecting these patients belonged to subgenotype 1B. This study provides valuable new data on anti-HAV prevalence among HCV carriers in Brazil. In the present study, we found a high proportion of patients with anti-HAV positivity, indicating that anti-HAV testing of HCV-infected patients is a cost-effective strategy and should be carried out before vaccination against HAV in these patients, particularly in regions such as our geographical area with high total anti-HAV prevalence.

    Conclusion: The study found that patients with chronic hepatitis C who received interferon plus ribavirin therapy had poor quality of life during the treatment period. There was significant difference among patients with different financial stress, and a negative relationship between tangible support and hepatitis quality of life. Financial stress and tangible support are predictors of quality of life for all subjects. The results of this study might assist healthcare personnel to comprehend the quality of life and its related factors in patients with chronic hepatitis C treated with antiviral therapy.

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

    Fibrosis blood tests have been validated in chronic hepatitis C. Their diagnostic accuracy is less documented in hepatitis B. The aim of this study was to describe the diagnostic performance of FibroTest®, FibroMeter®, and HepaScore® for liver fibrosis in hepatitis B compared to hepatitis C. 510 patients mono-infected with hepatitis B or C and matched on fibrosis stage were included. Blood tests were performed the day of the liver biopsy. Histological lesions were staged according to METAVIR. Fibrosis stages were distributed as followed: F0 n=76, F1 n=192, F2 n=132, F3 n=54, F4 n=56. Overall diagnostic performance of blood tests were similar between hepatitis B and C with AUROC ranging from 0.75 to 0.84 for significant fibrosis, 0.82 to 0.85 for extensive fibrosis and 0.84 to 0.87 for cirrhosis. Optimal cut-offs were consistently lower in hepatitis B compared to hepatitis C, especially for the diagnosis of extensive fibrosis and cirrhosis, with decreased sensitivity and negative predictive values. More hepatitis B than C patients with F ⩾3 were underestimated: FibroTest®: 47% vs. 26%, FibroMeter®: 24% vs. 6%, HepaScore®: 41% vs. 24%, pfibrosis underestimation. Overall the diagnostic performance of blood tests is similar in hepatitis B and C. The risk of underestimating significant fibrosis and cirrhosis is however greater in hepatitis B and cannot be entirely corrected by the use of more stringent cut-offs.

    Arsenic in drinking water is associated with hepatomegaly and death from liver cancer. However, confounding factors related to liver diseases have not been carefully studied. We examined associations between exposure of arsenic in drinking water and risk of hepatitis and cirrhosis, and the interaction with chronic viral hepatitis, in people living in the Lanyang Basin of northeastern Taiwan, where well water has an arsenic content that ranges from undetectable to 3590 μg/L. We tested blood samples from 4387 people who lived in arseniasis-endemic areas in northeastern Taiwan from 1991 through 1994 for hepatitis B virus DNA, hepatitis B surface antigen (HBsAg), and antibodies against hepatitis C virus (anti-HCV). We measured arsenic concentrations in well water and collected information on residents' histories of major chronic diseases. Reports of chronic hepatitis or cirrhosis were ascertained using the Taiwan National Health Insurance database. Reports of liver cancer were ascertained using the Taiwan National Cancer Registry. Prevalence odds ratios in the overall study population for chronic hepatitis or cirrhosis for well water arsenic concentrations of ≤10 μg/L were 1.00 (reference), 0.93 for 10.1-49.9 μg/L (95% confidence interval [CI], 0.57-1.52), 1.24 for 50.0-99.9 μg/L (95% CI, 0.68-2.23), 0.98 for 100.0-299.9 (95% CI, 0.52-1.85), and 1.86 for ≥300.0 μg/L (95% CI, 1.08-3.20). Increasing levels of arsenic in drinking water were associated with increasing prevalence of chronic hepatitis or cirrhosis in residents who were seronegative for HBsAg and seronegative for anti-HCV, but not for seropositive for either HBsAg or anti-HCV. In individuals who were seropositive for HBsAg or anti-HCV, we observed an inverse association between hepatitis or cirrhosis and consumption of water with levels of arsenic ≥100.0 μg/L. Among participants who were seropositive for HBsAg or anti-HCV, consumption of water with levels of arsenic ≥100.0 μg/L was associated

    Amiodarone is an amphiphilic, iodinated, benzofuran derivative that is known to be effective for refractory ventricular tachyarrhythmia. Amiodarone also is known to cause a variety of side effects, related to its accumulation in multiple organs. The deposition of amiodarone and its metabolite, desethylamiodarone (DA), in liver elevates liver function tests and increases liver attenuation on computed tomography (CT). Although several groups have reported increased liver attenuation in patients receiving chronic amiodarone therapy, there is still no clear statistically significant relationship between liver CT attenuation and the cumulative dose of amiodarone, or between plasma levels of amiodarone and DA. CT scans were originally performed for the evaluation of pulmonary fibrosis in 13 patients (7 men and 6 women; mean age, 69.9 years, range 35 to 86 years) receiving chronic amiodarone therapy. Liver CT attenuation tended to increase in these patients. We found no significant correlation between liver CT attenuation and the cumulative dose of amiodarone. However, the CT attenuation of the liver was correlated significantly with the plasma level of amiodarone and DA. It was also suggested that liver CT scan is a useful means of evaluating the plasma levels of amiodarone and DA, and for estimating their deposition in liver. (author)

  14. Impact of PNPLA3 and IFNL3 polymorphisms on hepatic steatosis in Asian patients with chronic hepatitis C.

    Directory of Open Access Journals (Sweden)

    Chao-Min Huang

    Full Text Available A recent meta-analysis revealed that the genotype PNPLA3 rs738409 GG is associated with a higher risk of hepatic steatosis (HS in Caucasian patients with chronic hepatitis C (CHC. However, controversial results were found regarding Asian populations. Furthermore, previous studies have shown a negative association between interferon lambda 3 (IFNL3 rs12979860 CC and HS in Caucasian CHC patients, but there have been no reports indicating any such association in Asian populations. In this study, then, we investigated the association of PNPLA3 and IFNL3 polymorphisms with HS in Asian CHC patients.We enrolled consecutive CHC patients who underwent liver biopsy prior to antiviral therapy. We excluded those patients with decompensated liver disease, any co-existing chronic liver disease, or HIV or HBV co-infection.1080 CHC patients were enrolled, and HS was found in 453 (41.9% patients. The frequency distribution of the G allele was significantly associated with HS (P<0.001, and this conferred a higher risk to G allele homozygotes (OR: 2.06, 95% CI: 1.46-2.88, P <0.001 than to G allele carriers (OR: 1.98, 95% CI: 1.52-2.58, P<0.001. There was a borderline significant difference in the prevalence of HS in rs12979860 CC versus non-CC (40.8% versus 49.3%, P = 0.059. After adjustment for age, sex, body mass index, diabetes, and excessive alcohol intake, the rs738409 G allele homozygote carriers still carried a higher risk for HS (OR: 1.93, 95% CI: 1.35-2.77, P = 0.003.The PNPLA3 rs738409 GG genotype is positively associated with HS, while the IFNL3 rs 12979860 CC genotype may be negatively associated with HS, in Asian CHC patients.

    To assess the frequency of antibodies to liver/kidney microsome type 1 (anti-LKM1) in patients with chronic active hepatitis, 131 such patients were tested by an indirect immunofluorescence assay. Of 62 patients with type 1 autoimmune hepatitis, none were seropositive. In contrast, 3 of 11 patients with autoimmune hepatitis and antimitochondrial antibodies (27%) were seropositive for anti-LKM1. Each had responded to corticosteroid therapy, and retesting of sera confirmed that each had been misclassified as antimitochondrial antibody positive. None of the patients with chronic active hepatitis B (14 patients) or C (24 patients) had anti-LKM1. Similarly, none of the 20 patients with cryptogenic disease had these antibodies. It is concluded that anti-LKM1 is specific for type 2 autoimmune hepatitis and is infrequent in adult patients seen at a referral center in the United States for chronic active hepatitis. Anti-LKM1 reactivity may be misinterpreted as antimitochondrial antibody reactivity by indirect immunofluorescence. Chronic hepatitis B and C virus infections are not important stimuli for the production of anti-LKM1, and testing for anti-LKM 1 is unlikely to clarify the nature of cryptogenic disease.

    Association between chronic hepatitis C virus (CHC) infection and type 2 diabetes mellitus has been challenging in recent decades. Despite of extensive research in this area, there is no general agreement on the direct effect of HCV infection on insulin resistance. The study was performed in 52 CHC patients (mean age = 39.48) and 52 and sex‑matched healthy Iranian controls, referred to the Hepatitis Clinic, Department of Gastroenterohepatology, Shiraz University of medical sciences, Shiraz, Iran, from 2012 to 2015. Fasting blood glucose level, fasting insulin level and insulin resistance defined as a homeostasis model assessment of insulin resistance (HOMA-IR) index were determined and compared between two groups. Insulin resistance was present in 26.9% of CHC patients and 34.62% of healthy controls. Mean HOMA index was 1.93 in patients and 2.18 in controls. There were no statistically significant differences between patient and control groups with regard to fasting insulin level, fasting blood glucose, HOMA index and insulin resistance. HOMA index and fasting insulin level were significantly higher in IR CHC patients relative to IR controls. Fasting blood glucose was also significantly higher in controls younger than 40 years. Results obtained in this study showed that chronic hepatitis C cannot be considered as a risk factor for insulin resistance and diabetes in Iranian population. However, regular screening for insulin resistance is recommended in CHC patients with age ≥ 40 years and fasting blood glucose ≥ 100 mg/dl.

    Chronic hepatitis B (CHB) is a condition that results in substantial morbidity and mortality worldwide because of progressive liver damage. Investigators undertaking economic evaluations of new therapeutic agents require estimates of health-related quality of life (HRQOL). Recently, evidence has begun to accumulate that differences in cultural backgrounds have a quantifiable impact on perceptions of health. The objective was to elicit utilities for six health states that occur after infection with the hepatitis B virus from infected and uninfected respondents living in jurisdictions with low and with high CHB endemicity. Standard gamble utilities were elicited from hepatitis patients and uninfected respondents using an interviewer-administered survey in the United States, Canada, United Kingdom, Spain, Hong Kong, and mainland China. Generalized linear models were used to the effect on utilities of current health, age and sex, jurisdiction and, for infected respondents, current disease state. The sample included 534 CHB-infected patients and 600 uninfected respondents. CHB and compensated cirrhosis had a moderate impact on HRQOL with utilities ranging from 0.68 to 0.80. Decompensated cirrhosis and hepatocellular carcinoma had a stronger impact with utilities ranging from 0.35 to 0.41. Significant variation was observed between countries, with both types of respondents in mainland China and Hong Kong reporting systematically lower utilities. Health states related to CHB infection have substantial reductions in HRQOL and the utilities reported in this study provide valuable information for comparing new treatment options. The observed intercountry differences suggest that economic evaluations may benefit from country-specific utility estimates. The extent that systematic intercountry differences in utilities hold true for other infectious and chronic diseases remains an open question and has considerable implications for the proper conduct and interpretation of

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

    Full text: The chronic virus hepatitis produces numerous abnormalities of liver function. The viruses of B, C, D, F and G hepatitis possess the ability to cause chronically proceeding diseases. Earlier we have found that binding ability of serum albumin at patients with acute forms of virus hepatitis is authentically reduced in comparison with the given parameters of control group. At an acute virus hepatitis B with middle severity the reducing of binding ability of serum albumin was observed at 70 % of patients. At an acute virus hepatitis A the reduce of binding ability of serum albumin is less expressed than at acute virus hepatitis B. At of chronic virus intoxication in human organism there is a formation and accumulation of toxic compounds in the excessive concentrations, which are not inherent to a normal metabolism. One of universal mechanisms of reaction of an organism on the increasing concentration of metabolism products is formation of complexes of various compounds with blood plasma proteins. The formation in an organism of endo- and exotoxins excessive concentrations results in blocking the binding centers of albumin molecule that causes the change of its complexing ability. The purpose of the present research: investigation of binding ability of serum albumin with use of radiochemical method at children with a chronic virus hepatitis B and C. Materials and methods. Under clinical observation there were 52 children in the age from 3 till 14 years. From them at 32 the chronic virus hepatitis B was confirmed, at 20 chronic virus - hepatitis C. Etiological diagnostics was carried out by definition of specific markers of a hepatitis B and C method IFA and PCR. Binding ability of serum albumin was defined by radiochemical method with use of the tritium labeled no-spa (drotaverine hydrochloride). The control group consists from 10 conditionally health children of similar age. Results and their discussion. The results of investigation have shown, that at a

    Full Text Available Frequently, patients with hepatitis C virus (HCV chronic infection have high levels of serum anti-thyroperoxidase and/or anti-thyroglobulin autoantibodies, ultrasonographic signs of chronic autoimmune thyroiditis, and subclinical hypothyroidism, in female gender versus healthy controls, or hepatitis B virus infected patients. In patients with “HCV-associated mixed cryoglobulinemia” (MC + HCV, a higher prevalence of thyroid autoimmune disorders was shown not only compared to controls, but also versus HCV patients without cryoglobulinemia. Patients with MC + HCV or HCV chronic infection show a higher prevalence of papillary thyroid cancer than controls, in particular in patients with autoimmune thyroiditis. Patients with HCV chronic infection, or with MC + HCV, in presence of autoimmune thyroiditis, show higher serum levels of T-helper (Th1 (C-X-C motif ligand 10 (CXCL10 chemokine, but normal levels of Th2 (C-C motif ligand 2 chemokine, than patients without thyroiditis. HCV thyroid infection could act by upregulating CXCL10 gene expression and secretion in thyrocytes recruiting Th1 lymphocytes that secrete interferon-γ and tumor necrosis factor-α. These cytokines might induce a further CXCL10 secretion by thyrocytes, thus perpetuating the immune cascade, which may lead to the appearance of autoimmune thyroid disorders in genetically predisposed subjects. A careful monitoring of thyroid function, particularly where nodules occur, is recommended in HCV patients.

    Full Text Available Abstract Background Hepatitis B virus (HBV infection continues to be an escalating global health problem. Feasible and effective animal models for HBV infection are the prerequisite for developing novel therapies for this disease. The tree shrew (Tupaia is a small animal species evolutionary closely related to humans, and thus is permissive to certain human viral pathogens. Whether tree shrews could be chronically infected with HBV in vivo has been controversial for decades. Most published research has been reported on adult tree shrews, and only small numbers of HBV infected newborn tree shrews had been observed over short time periods. We investigated susceptibility of newborn tree shrews to experimental HBV infection as well as viral clearance over a protracted time period. Results Forty-six newborn tree shrews were inoculated with the sera from HBV-infected patients or tree shrews. Serum and liver samples of the inoculated animals were periodically collected and analyzed using fluorescence quantitative polymerase chain reaction, enzyme-linked immunosorbent assay, Southern blot, and immunohistochemistry. Six tree shrews were confirmed and four were suspected as chronically HBV-infected for more than 48 (up to 228 weeks after inoculation, including three that had been inoculated with serum from a confirmed HBV-infected tree shrew. Conclusions Outbred neonatal tree shrews can be long-term chronically infected with HBV at a frequency comparable to humans. The model resembles human disease where also a smaller proportion of infected individuals develop chronic HBV related disease. This model might enable genetic and immunologic investigations which would allow determination of underlying molecular causes favoring susceptibility for chronic HBV infection and disease establishment vs. viral clearance.

    Recent studies in adult patients have established a relationship between hepatitis C virus infection and the presence of liver-kidney microsomal autoantibody type 1 (LKM1). Conversely, little is known regarding the relationship between hepatitis C and autoimmunity in children. In this study, we investigated non-organ specific autoantibodies in 40 otherwise healthy Italian children with chronic hepatitis C. All but four patients included in the study were asymptomatic. Liver histology, obtained in 35, showed features ranging from minimal to mild chronic hepatitis. Autoantibodies were investigated by indirect immunofluorescence. HCV RNA was assayed by the polymerase chain reaction in 34 cases and viral genotypes were determined. Antinuclear antibodies were detected in three (7.5%) cases, one with a homogeneous pattern; smooth muscle autoantibodies in seven (17.5%) cases, always with V (vessels only) specificity and LKM1 in four (10%), at titers ranging from 1:20 and 1:2560. Clinical and virologic features did not significantly differ between autoantibody positive and negative cases, although infections with HCV genotypes 1a and 2 were more frequent in LKM1-positive patients. During observation, the child with the highest LKM1 titre was unsuccessfully treated with alpha interferon but responded to steroids. Twelve LKM1 negative children were also treated with interferon and one developed low LKM1 titers concomitant with an alanine aminotransferase flare. The sera of the five LKM1-positive children with investigated by immunoblotting with a human microsomal fraction and peptide 257-269 of cytochrome P450IID6. Only the serum of the child with the highest LKM1 titers was reactive. These results show that a consistent proportion of children with chronic hepatitis C circulate non-organ specific autoantibodies. The prevalence of LKM1 is greater than in adults and this could raise problems for the treatment of the disease with interferon. The analysis of LKM1 target antigens

    Chronic migraine is a primary headache that is difficult to treat and has an important impact on the patient's quality of life. The international headache classification recently modified the criteria for chronic migraine and therefore few studies have been conducted that analyse groups according to these new criteria. AIM. To analyse a group of patients with chronic migraine who were referred to a general neurology service. The first 100 patients with migraine were selected. Researchers established and analysed a number of subgroups of patients with episodic, chronic or chronic migraine with probable headache due to medication abuse, in accordance with the International Headache Society (IHS) headache classification and its revised version from 2006. Of the total sample of 738 new patients, 100 (13.5%) suffered from migraines and of these 100 new patients with migraine 42 (5.6% of the total series) satisfied criteria for chronic migraine and 15 patients with chronic migraine met the criteria for probable headache due to medication abuse. Before visiting the neurology service, only 41% had been diagnosed as suffering from migraine, 38% had received no information about this condition, only 17% took triptans for symptomatic relief and 23% had followed some kind of preventive treatment. One notable finding was the importance of episodic and chronic migraine in a general neurology service, on applying the recent IHS criteria. A high percentage of patients with chronic migraine who were referred to the neurology service have not been diagnosed or given any information or proper treatment; an elevated degree of self-medication and medication abuse also exists. Preventive treatment and triptans in cases of intense migraines are still not commonly used in primary care.

    We report a case of 61-yr-old man with stable psoriasis who progressively developed generalized pustular eruption, erythroderma, fever, and hepatic dysfunction following oral terbinafine. Skin biopsy was compatible with pustular psoriasis. After discontinuation of terbinafine and initiating topical corticosteroid and calcipotriol combination with narrow band ultraviolet B therapy, patient'S condition slowly improved until complete remission was reached 2 weeks later. The diagnosis of generalized pustular psoriasis (GPP) induced by oral terbinafine was made. To our knowledge, this is the first report of GPP accompanied by hepatic dysfunction associated with oral terbinafine therapy. PMID:17297275

    2003-01-01

    Full Text Available On the last twenty years, viral hepatitis has emerged as a serious problem in almost all the Amerindian communities studied in the Amazon Basin and in other Amazon-related ecological systems from the North and Center of South America. Studies performed on communities from Bolivia, Brazil, Colombia, Peru and Venezuela have shown a high endemicity of the hepatitis B virus (HBV infection all over the region, which is frequently associated to a high prevalence of infection by hepatitis D virus among the chronic HBV carriers. Circulation of both agents responds mainly to horizontal virus transmission during childhood through mechanisms that are not fully understood. By contrast, infection by hepatitis C virus (HCV, which is present in all the urban areas of South America, is still very uncommon among them. At the moment, there is not data enough to evaluate properly the true incidence that such endemicity may have on the health of the populations affected. Since viral transmission might be operated by mechanisms that could not be acting in other areas of the World, it seems essential to investigate such mechanisms and to prevent the introduction of HCV into these populations, which consequences for health could be very serious.

    Full Text Available Aim. To investigate whether hyperglycemia will aggravate hepatic ischemia reperfusion injury (HIRI and the underlying mechanisms. Methods. Control and streptozotocin-induced diabetic Sprague-Dawley rats were subjected to partial hepatic ischemia reperfusion. Liver histology, transferase, inflammatory cytokines, and oxidative stress were assessed accordingly. Similarly, BRL-3A hepatocytes were subjected to hypoxia/reoxygenation (H/R after high (25 mM or low (5.5 mM glucose culture. Cell viability, reactive oxygen species (ROS, and activation of nuclear factor-erythroid 2-related factor 2 (Nrf2 and nuclear factor of kappa light polypeptide gene enhancer in B-cells (NF-κB were determined. Results. Compared with control, diabetic rats presented more severe hepatic injury and increased hepatic inflammatory cytokines and oxidative stress. HIRI in diabetic rats could be ameliorated by pretreatment of N-acetyl-L-cysteine (NAC or apocynin. Excessive ROS generation and consequent Nrf2 and NF-κB translocation were determined after high glucose exposure. NF-κB translocation and its downstream cytokines were further increased in high glucose cultured group after H/R. While proper regulation of Nrf2 to its downstream antioxidases was observed in low glucose cultured group, no further induction of Nrf2 pathway by H/R after high glucose culture was identified. Conclusion. Hyperglycemia aggravates HIRI, which might be attributed to chronic oxidative stress and inflammation and potential malfunction of antioxidative system.

    Full Text Available Aim: Alpha-fetoprotein (AFP has been widely used as a diagnostic marker for hepatocellular carcinoma. Some patients with hepatitis C show high AFP values, but no evidence of hepatocellular carcinoma. The aim of this study is to assess the influence of antiviral treatment on the serum AFP in patients with chronic hepatitis C without hepatocellular carcinoma. Material and Method: Thirty seven chronic hepatitis C patients (20 females and 17 males were included in the study. All patients were given a combined treatment of pegylated or conventional interferon (IFN and ribavirin. Serum AFP was measured at baseline and on months 3-6-12 of the therapy. Results: Compared to the pretreatment levels of ALT (88,59 ± 57,22 IU, those at 3, 6 and 12 months were statistically lower (p0,05, to 4,34 ± 4,64 (p>0,05 and to 2,63 ± 2,17 (p10 ng/ml. In these patients, mean serum AFP levels were decreased from pretreatment level of 15,09 ± 5,92 ng/ml to 11,39±3,30, to 6,97±2,53 (p

    Full Text Available Inflammation has significant impacts on liver fibrosis measurement by ultrasound elastography. The interpretation requires further optimization in patients with or without anti-viral therapy. We prospectively enrolled a consecutive series of patients with chronic hepatitis B who received liver histology analysis and acoustic radiation force impulse (ARFI. 146 patients who underwent liver biopsy (50.9% or tumor resection (49.1% were enrolled. 34 patients (23.3% had been receiving anti-hepatitis B therapy of various duration. The areas under the receiver-operating characteristic (AUROC for the diagnosis of Metavir F4 by mean ARFI was 0.820 in the non-treatment group and 0.796 in the treatment group. The ARFI tended to be not lower (100% than the corresponding Metavir grading in patients with treatment within 12 months, equal (75% from 13 to 31 months, and lower (71.4% after 32 months. We conclude that ARFI is a reliable tool for measurement of liver fibrosis in chronic hepatitis B patients with ALT (alanine aminotransferase <5x the upper limit of normal. For those patients under anti-HBV therapy, the optimal timing for ARFI analysis will be over 1–2.5 years of nucleos(tide analogue therapy. The ARFI measurement after 2.5 years tends to be lower than the corresponding histology grading.

    Serial sera were collected prospectively during the clinical course of 13 HBsAg carriers with chronic liver disease and analyzed for ALT levels, pre-S1 and pre-S2 antigens and corresponding antibodies and other serological hepatitis B virus markers. In five patients, anti-pre-S1 and anti-pre-S2 antibodies became detectable in multiple serum samples, whereas in eight patients anti-pre-S was never detected or only appeared transiently during the follow-up. The first pattern was associated with normalization of ALT levels and undetectable pre-S antigens and viral DNA by the polymerase chain reaction assay at final follow-up. HBsAg clearance occurred in two of the five patients. The second pattern was one of persistence of HBsAg and pre-S antigens, associated with the presence of serum HBV DNA detectable by spot hybridization or polymerase chain reaction regardless of clinical outcome. These findings demonstrate the occurrence of anti-pre-S antibodies in chronic hepatitis B virus-induced liver disease and associate anti-pre-S appearance with the clearance of hepatitis B virus from serum.

    Adverse Events Following Immunization in Viet Nam in 2013 led to substantial reductions in hepatitis B vaccination coverage (both the birth dose and the three-dose series). In order to estimate the impact of the reduction in vaccination coverage on hepatitis B transmission and future mortality, a widely-used mathematical model was applied to the data from Viet Nam. Using the model, we estimated the number of chronic infections and deaths that are expected to occur in the birth cohort in 2013 and the number of excessive infections and deaths attributable to the drop in immunization coverage in 2013. An excess of 90,137 chronic infections and 17,456 future deaths were estimated to occur in the 2013 birth cohort due to the drop in vaccination coverage. This analysis highlights the importance of maintaining high vaccination coverage and swiftly responding to reported Adverse Events Following Immunization in order to regain consumer confidence in the hepatitis B vaccine.

    2005-09-01

    Anti-liver-kidney microsome type 1 (LKM1) autoantibodies directed against the cytochrome P450 2D6 (CYP2D6) are considered specific markers of type 2 autoimmune hepatitis, but are also found in 5% of sera from patients chronically infected by hepatitis C virus (HCV). Molecular mimicry between HCV proteins and CYP2D6 has been proposed to explain the emergence of these autoantibodies. Anti-LKM1 autoantibodies from hepatitis C-infected patients were affinity-purified against immobilized CYP2D6 protein and used to screen a phage display library. CYP2D6 conformational epitopes were identified using phage display analysis and the identification of statistically significant pairs (SSPs). Cross-reactivity between CYP2D6 and HCV protein candidates was tested by immunoprecipitation. Nineteen different clones were isolated, and their sequencing resulted in the mapping of a conformational epitope to the region of amino acids 254-288 of CYP2D6. Candidate HCV proteins for molecular mimicry included: core, E2, NS3 and NS5a. Affinity-purified autoantibodies from HCV+/LKM1+ patients immunoprecipitated either NS3, NS5a, or both, and these reactivities were specifically inhibited by immobilized CYP2D6. In conclusion, HCV+/LKM1+ sera recognize a specific conformational epitope on CYP2D6 between amino acids 254 to 288, the region that contains the major linear epitope in type 2 autoimmune hepatitis patients. Cross-reactivity due to molecular mimicry at the B-cell level was shown between the CYP2D6 and the HCV NS3 and NS5a proteins and could explain the presence of anti-LKM1 in patients chronically infected with HCV. Further investigation of the role played by this molecular mimicry in HCV-infected patients may lead to more specific strategies for diagnosis and treatment.

    Full Text Available Purpose. To study the features of the progression of chronic hepatitis C in children with different variants of polymorphism of the gene IL-28B. Materials and methods. The study involved 57 children aged 3–18 years with CHC. All patients were involved in clinical, laboratory and instrumental examination. The stage of fibrosis was assessed morphologicallyon a scale METAVIR, by the calculation method — Fibro Test, on APRI index, and by the concentration of hyaluronic acid (HA, transforming growth factor TGF- β1 in serum usingIFA. The SNP genotypes of rs8099917 and rs12979860 lociin IL-28B were determinedby the method of the polymer chain reaction (PCR. A statistical analysis of the data was conducted. Resume. Most of the patients were children with chronic hepatitis C who had genotype CT at rs12979860 locus of the gene IL-28B (54% and the TT geno-type at rs8099917 locus (60%. It was found that fibrogenesis in the liver of patients with chronic hepatitis C depends on the polymorphism of the gene IL-28B. Unfavorable genotypevariants for the development of liver fibrosis are: TT (rs12979860, CT (rs12979860 and TG/GG (rs8099917. Variants CC (rs12979860 and TT (rs8099917 have a beneficial effect on the course of chronic hepatitis C, including patients with a lower stage of fibrosis. To determine the risk of progression of chronic hepatitis C it may be sufficient to determine the polymorphism of rs12979860locusin the gene IL-28B. Conclusions.The polymorphism variants CC (rs12979860 and TT (rs8099917of the gene IL-28Bare more favorable (lower severity of fibrosis in the progression of chronic hepatitis C in children. Variant TT (rs12979860 in the polymorphism of the gene IL-28B is associated with the progression of hepatitis — faster development of liver fibrosis.

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

    Chronic hepatitis B virus (HBV) infection is a major cause of liver morbidity and mortality worldwide. While a proportion of the 250 million individuals chronically infected with HBV will not come to significant harm or require therapy, many others risk developing complications of the end-stage liver disease such as decompensated cirrhosis and hepatocellular carcinoma (HCC), without intervention. Due to the complex natural history of HBV infection, patients require an expert assessment to interpret biochemistry, viral serology and appropriately stage the disease, and to initiate monitoring and/or therapy where indicated. The detection and quantification of liver fibrosis is a key factor for disease management and prognostication for an individual with HBV. The reliance on invasive liver biopsy to stage disease is diminishing with the advent of robust non-invasive blood- and imaging-based algorithms which can reliably stage disease in many cases. These tests are now incorporated into International guidelines for HBV management and relied upon daily to inform clinical judgement. Both blood- and imaging-based approaches have advantages over liver biopsy, including minimal risks, lower cost, better patient acceptance and speed of results, while disadvantages include lower diagnostic accuracy in intermediate disease stages and variability with co-existing hepatic inflammation or steatosis. This review outlines the methods of fibrosis assessment in chronic HBV infection and focuses on the most commonly used blood- and imaging-based non-invasive tests, reviewing their diagnostic performance and applicability to patient care.

    Full Text Available The hepatitis B virus is second only to tobacco as a known human carcinogen. However, chronic hepatitis B usually does not produce symptoms and people feel healthy even in the early stages of live cancer. Therefore, chronically infected people should perceive it as a serious health problem and move on to appropriate health behaviour. The purpose of this paper is to develop and validate an online program for promoting self-management among Korean patients with chronic hepatitis B. The online program was developed using a prototyping approach and system developing life cycle method, evaluated by users for their satisfaction with the website and experts for the quality of the site. To evaluate the application of the online program, knowledge and self-management compliance of the subjects were measured and compared before and after the application of the online program. There were statistically significant increases in knowledge and self-management compliance in the user group. An online program with high accessibility and applicability including information, motivation, and behavior skill factors can promote self-management of the patient with chronic hepatitis B. Findings from this study allow Korean patients with chronic hepatitis B to engage in proactive and effective health management in the community or clinical practice.

    The effects of chronic ethanol feeding on protein and glycoprotein synthesis and secretion were studied in rat liver slices. Liver slices from rats fed ethanol for 4-5 wk showed a decreased ability to incorporate [ 14 C]glucosamine into medium trichloracetic acid-precipitable proteins when compared to the pair-fed controls; however, the labeling of hepatocellular glycoproteins was unaffected by chronic ethanol treatment. Immunoprecipitation of radiolabeled secretory (serum) glycoproteins with antiserum against rat serum proteins showed a similar marked inhibition in the appearance of glucosamine-labeled proteins in the medium of slices from ethanol-fed rats. Minimal effects, however, were noted in the labeling of intracellular secretory glycoproteins. Protein synthesis, as determined by measuring [ 14 C]leucine incorporation into medium and liver proteins, was decreased in liver slices from ethanol-fed rats as compared to the pair-fed controls. This was the case for both total proteins as well as immunoprecipitable secretory proteins, although the labeling of secretory proteins retained in the liver slices was reduced to a lesser extent than total radiolabeled hepatic proteins. When the terminal sugar, [ 14 C]fucose, was employed as a precursor in order to more closely focus on the final steps of hepatic glycoprotein secretion, liver slices obtained from chronic ethanol-fed rats exhibited impaired secretion of fucose-labeled proteins into the medium. When ethanol (5 or 10 mM) was added to the incubation medium containing liver slices from the ethanol-fed rats, the alterations in protein and glycoprotein synthesis and secretion caused by the chronic ethanol treatment were further potentiated. The results of this study indicate that liver slices prepared from chronic ethanol-fed rats exhibit both impaired synthesis and secretion of proteins and glycoproteins, and these defects are further potentiated by acute ethanol administration

    Vitamin C and vitamin E supplementations and their beneficial effects on type 2 diabetes mellitus (T2DM) have been subjected to countless controversial data. Hence, our aim is to investigate the hepatic molecular mechanisms of any diabetic predisposing risk of the chronic administration of different doses of vitamin E or vitamin C in rats. The rats were supplemented with different doses of vitamin C or vitamin E for eight months. Vitamin C and vitamin E increased fasting blood glucose, insulin, and homeostasis model assessment index for insulin resistance (HOMA). Vitamin C disrupted glucose tolerance by attenuating upstream hepatic insulin action through impairing the phosphorylation and activation of insulin receptor and its subsequent substrates; however, vitamin E showed its effect downstream insulin receptor in the insulin signaling pathway, reducing hepatic glucose transporter-2 (GLUT2) and phosphorylated protein kinase (p-Akt). Moreover, both vitamins showed their antioxidant capabilities [nuclear factor-erythroid-2-related factor 2 (Nrf2), total and reduced glutathione] and their negative effect on Wnt pathway [phosphorylated glycogen synthase kinase-3β (p-GSK-3β)], by altering the previously mentioned parameters, inevitably leading to severe reduction of reactive oxygen species (ROS) below the physiological levels. In conclusion, a detrimental effect of chronic antioxidant vitamins supplementation was detected; leading to insulin resistance and impaired glucose tolerance obviously through different mechanisms. Overall, these findings indicate that the conventional view that vitamins promote health benefits and delay chronic illnesses and aging should be modified or applied with caution. Copyright © 2017.

    The low-grade inflammation and insulin resistance are two events that could be present in varying degrees, on obesity and chronic diseases. The degree of subclinical inflammation can be gauged by measuring the concentrations of some inflammatory biomarkers, including the hepatic origin ones. Some of those biomarkers are sialic acid, α1-antitrypsin and the C-terminal fragment of alpha1-antitrypsin, ceruloplasmin, fibrinogen, haptoglobin, homocystein and plasminogen activator inhibitor-1. To approach the relation between adiposity and hepatic inflammatory markers, and to assess the possible associations between hepatic inflammatory biomarkers and obesity, as well as their capacity of predicting chronic diseases such as type 2 diabetes and atherotrombotic cardiovascular diseases. We used electronic scientific databases to select articles without restricting publication year. The sialic acid predicts the chance increase to become type 2 diabetic independently of BMI. Moreover, the α1-antitripsin, ceruloplasmin, fibrinogen and haptoglobulin biomarkers, seem predict the chance increase to become type 2 diabetic, dependently, of BMI. So, this process could be aggravated by obesity. The concentrations of fibrinogen, homocystein and PAI-1 increase proportionally to insulin resistance, showing its relation with metabolic syndrome (insulin resistance state) and with type 2 diabetes. In relation to cardiovascular diseases, every biomarkers reported in this review seem to increase the risk, becoming useful in add important prognostic. This review integrates the knowledge concerning the possible interactions of inflammatory mediators, in isolation or in conjunction, with obesity and chronic diseases, since these biomarkers play different functions and follow diverse biochemical routes in human body metabolism.

    Mei-Zhu Hong

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

    Coffee is associated with a reduced risk of hepatocellular carcinoma in patients with chronic C hepatitis. This prospective trial was aimed at assessing the mechanisms underlying coffee-related protective effects. Forty patients with chronic hepatitis C were randomized into two groups: the first consumed 4 cups of coffee/day for 30 days, while the second remained coffee "abstinent". At day 30, the groups were switched over for a second month. At baseline, aspartate aminotransferase and alanine aminotransferase were lower in patients drinking 3-5 (Group B) than 0-2 cups/day (Group A) (56 ± 6 vs 74 ± 11/60 ± 3 vs 73 ± 7 U/L p=0.05/p=0.04, respectively). HCV-RNA levels were significantly higher in Group B [(6.2 ± 1.5) × 10(5)vs (3.9 ± 1.0) × 10(5)UI/mL, p=0.05]. During coffee intake, 8-hydroxydeoxyguanosine and collagen levels were significantly lower than during abstinence (15 ± 3 vs 44 ± 16 8-hydroxydeoxyguanosine/10(5)deoxyguanosine, p=0.05 and 56 ± 9 vs 86 ± 21 ng/mL, p=0.04). Telomere length was significantly higher in patients during coffee intake (0.68 ± 0.06 vs 0.48 ± 0.04 Arbitrary Units, p=0.006). Telomere length and 8-hydroxydeoxyguanosine were inversely correlated. In chronic hepatitis C coffee consumption induces a reduction in oxidative damage, correlated with increased telomere length and apoptosis, with lower collagen synthesis, factors that probably mediate the protection exerted by coffee with respect to disease progression.

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

    Full Text Available Examination of 125 children with chronic hepatitis В and concomitant anemia has determined the frequency of refractory forms of anemia (52,5%. The disease progressed more severely on the background of anemia, which was indicated by the prevalence of CHВ forms with severe activity (71,4%. The pathognomonic symptoms of anemic processes were revealed. Two pathogenetic variants of the anemia genesis in children with CHВ are being considered: the first is defined by veritable iron deficiency with ferrokinetic markers of iron-deficiency anemia; the second — by relocationable iron deficit that is typical for hemosiderosis and refractoriness development.

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

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

    The hepatitis D virus super-infection contributes significantly to the morbidity and mortality of hepatitis B virus infection. The objectives were to describe the incidence of Hepatitis D virus and comparative analysis of disease activity in patients of chronic hepatitis B virus, with and without super-infection of hepatitis D virus. This Cross-sectional comparative study was conducted at Department of Medicine and Gastroenterology Clinic Jinnah Postgraduate Medical Centre, Karachi, Pakistan from February 2007 to July 2007. HBsAg positive patients who attended our Gastroenterology clinic were selected for the study. After screening for Anti-HDV these patients were segregated in to Anti-HDV positive and negative groups. Data was analyzed on SPSS 12. Eighty-four patients were selected. Seventy-three patients who fulfilled the inclusion criteria were enrolled in to the study. Anti-HDV was positive in 23 (31.5%) patients. Among these 23 anti-HDV positive, HDV-RNA was detected in 15 (75%) patients. The differences of age, gender, marital status and area of residence whether rural or urban were not significant between the two groups. HBV-DNA was significantly suppressed in majority of anti- HDV positive patients (p=0.019). Mean serum ALT levels were significantly higher in patients who had HDV infection (p=0.014). HDV infection was common in this series of patients with a frequency of 31.5%. All patients of chronic HBV should be screened for HDV whether they are asymptomatic HBV carriers or have chronic active hepatitis particularly when they have raised serum ALT. (author)

    To investigate the impact of the baseline status of patients with hepatitis B virus-associated acute-on-chronic liver failure on short-term outcomes. A retrospective study was conducted that included a total of 138 patients with hepatitis B virus-associated acute-on-chronic liver failure admitted to the Department of Infectious Diseases, Taihe Hospital, Hubei University of Medicine, from November 2013 to October 2016. The patients were divided into a poor prognosis group (74 patients) and a good prognosis group (64 patients) based on the disease outcome. General information, clinical indicators and prognostic scores of the patients' baseline status were analyzed, and a prediction model was established accordingly. Elder age, treatment with artificial liver support systems and the frequency of such treatments, high levels of white blood cells, neutrophils, neutrophil count/lymphocyte count ratio, alanine aminotransferase, gamma-glutamyl transferase, total bilirubin, urea, and prognostic scores as well as low levels of albumin and sodium were all significantly associated with the short-term outcomes of hepatitis B virus-associated acute-on-chronic liver failure. The predictive model showed that logit (p) = 3.068 + 1.003 × neutrophil count/lymphocyte count ratio - 0.892 × gamma-glutamyl transferase - 1.138 × albumin - 1.364 × sodium + 1.651 × artificial liver support therapy. The neutrophil count/lymphocyte count ratio and serum levels of gamma-glutamyl transferase, albumin and sodium were independent risk factors predicting short-term outcomes of hepatitis B virus-associated acute-on-chronic liver failure, and the administration of multiple treatments with artificial liver support therapy during the early stage is conducive to improved short-term outcomes.

    To analyze the prevalence and clinical characteristics of chronic hepatitis B virus (HBV) infection in a large series of patients with Sjögren syndrome (SS). We investigated the prevalence of chronic HBV infection in 603 consecutive patients with SS diagnosed in our department between 1994 and 2008. There were 517 patients with primary SS (482 women and 35 men, with a mean age at the time of fulfillment of the classification criteria of 57 years) and 86 patients with SS associated with chronic HCV infection (66 women and 20 men, with a mean age at the time of fulfillment of the classification criteria of 65 years). All patients fulfilled 4 or more of the 1993 European Community Study Group criteria for SS. The presence of HBsAg+ was detected in five (0.83%) of the 603 patients with SS. All HBsAg+ patients had primary SS. No patient with HCV-related SS had HBV coinfection. There were 4 women and 1 man, with a mean age at diagnosis of primary SS of 65 years (range 31 to 89 years). All patients showed sicca and systemic involvement. The main extraglandular feature was articular involvement in 5 (100%) patients (including arthritis in two). The main immunologic features were RF in 4 (80%) patients and ANA in 3 (60%). No patient had hypocomplementemia, cryoglobulinemia, antimitochondrial or anti-LKM1 antibodies. Liver involvement was detected in two patients and consisted of slightly raised levels of transaminases. No patient showed clinical manifestations of liver disease such as hepatomegaly, splenomegaly, jaundice or clinical features of hepatic decompensation (ascites, encephalopathy or gastrointestinal bleeding). We found a prevalence of chronic HBV infection of 0.83% in SS, very similar to the prevalence in general population in Spain (0.7%). In contrast to the close association between SS and HCV, chronic HBV infection is not associated with SS in our geographical area, with a ratio SS-HBV/SS-HCV cases of 1:10.

    A group of 24 patients with acute viral hepatitis B was assessed for specific antibodies against the ''core'' antigen class IgM (HB/sub c/AB IgM) during 1st-4th week of the illness. These specific antibodies were positive in all patients, the mean titre being 10/sup -5/. The high content of these antibodies persisted for 1-2 months after the onset of the disease. The assessment of specific antibodies against ''core'' antigen class IgM was also made in a group of 39 patients with chronic hepatitis. In these patients positive HB/sub c/Ab IgM with a lower content were found (titre 10/sup -3/) than in the group with acute viral hepatitis B. Based on the results the conclusion is made that specific antibodies HB/sub c/Ab class IgM are, in addition to the estimation of the surface antigen of the hepatitis B virus (HB/sub s/Ag), one more indicator of acute viral hepatitis B. The assessment is diagnostically valuable, in particular in acute hepatitis of obscure etiology, in acute jaundice of obscure etiology for the period of low and short-term antigenemia.

    2004-04-01

    Hepatitis C virus (HCV) has been estimated by the WHO to infect 170 million patients worldwide, with a high prevalence rate (about 24.5%) among Egyptians. The disease could be presented with variable hepatic lesions ranging from mild inflammation, fibrosis, cirrhosis to even end stage liver disease and hepatocellular carcinoma. The Knodell histology activity index, published in 1981, was the first system of its type and is widely regarded as the benchmark for objective, semi-quantitative reproducible description of the various morphological lesions of chronic hepatitis. Other proposals for semi-quantitative evaluation have followed. In this study, when applying these systems on the present cases (109 liver biopsies taken from Egyptian patients infected with HCV), the authors found that the presented histopathological features may be unusual for any of the known scoring systems. Therefore, they suggested a new system for grading and staging of liver diseases in Egyptian patients infected with HCV. Accordingly, the degrees of necroinflammations are classified into 3 grades (1-3) and the progression of fibrosis is classified into 3 stages (1-3). The reduced numbers of grades and stages proposed in this study may be attributed to the rapid course among Egyptians who differ in environmental circumstances from abroad.

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

    Full Text Available Hepatitis C virus (HCV infection has been associated with autoimmunity and extrahepatic manifestations in adults. Few data are available on these topics in children. Nonorgan specific auto-antibodies development is part of the natural course of chronic hepatitis C in children. Smooth muscle autoantibody is the most common autoantibody found, while liver-kidney microsomal type-1 antibody positivity is the most peculiar autoimmune feature of children with HCV infection. The clinical significance of non-organ specific autoantibodies in the course of paediatric chronic hepatitis C is still debated. Autoantibody positivity can be considered neutral for most patients, while it can be associated with negative connotations for others, especially those positive for liver-kidney microsomal type-1 autoantibody. Subclinical hypothyroidism but not autoimmune thyroiditis has been demonstrated in HCV infection in children, while only few cases of HCV-associated membranoproliferative glomerulonephritis have been described. Single reports are available in the literature reporting the anecdotal association between chronic hepatitis C and other extrahepatic manifestations such as myopathy and opsoclonus-myoclonus syndrome. Despite the low incidence of extrahepatic manifestations of chronic hepatitis C in children, overall, available data suggest a careful monitoring.

    AIM To investigate the association between hepatic steatosis and change in left ventricular mass index (LVMI) over five years, and examine whether systolic and diastolic blood pressures are mediators of the association between hepatic steatosis and LVMI using a general population sample. METHODS We analyzed data from the Study of Health in Pomerania. The study population comprised 1298 individuals aged 45 to 81 years. Hepatic steatosis was defined as the presence of a hyperechogenic pattern of the liver together with elevated serum alanine transferase levels. Left ventricular mass was determined echocardiographically and indexed to height2.7. Path analyses were conducted to differentiate direct and indirect paths from hepatic steatosis to LVMI encompassing systolic and diastolic blood pressure as potential mediating variables. RESULTS Hepatic steatosis was a significant predictor for all measured echocardiographic characteristics at baseline. Path analyses revealed that the association of hepatic steatosis with LVMI change after five years was negligibly small (β = -0.12, s.e. = 0.21, P = 0.55). Systolic blood pressure at baseline was inversely associated with LVMI change (β = -0.09, s.e. = 0.03, P < 0.01), while no association between diastolic blood pressure at baseline and LVMI change was evident (β = 0.03, s.e. = 0.05, P = 0.56). The effect of the indirect path from hepatic steatosis to LVMI via systolic baseline blood pressure was small (β = -0.20, s.e. = 0.10, P = 0.07). No indirect effect was observed for the path via diastolic baseline blood pressure (β = 0.03, s.e. = 0.06, P = 0.60). Similar associations were observed in the subgroup of individuals not receiving beta-blockers, calcium channel blockers, or drugs acting on the renin-angiotensin system. CONCLUSION Baseline associations between hepatic steatosis and LVMI do not extend to associations with LVMI change after five years. More studies are needed to study the longitudinal effects of hepatic

    AIM:To evaluate the effects of fucoidan,a complex sulfated polysaccharide extract from marine seaweed,on hepatitis C virus (HCV) RNA load both in vitro and in vivo.METHODS:HCV-1b replicon-expressing cells were cultured in the presence of fucoidan obtained from Cladosiphon okamuranus Tokida cultivated in Okinawa,Japan,and quantified the level of HCV replication.In an open-label uncontrolled study,15 patients with chronic hepatitis C,and HCV-related cirrhosis and hepatocellular carcinoma were treated with fucoidan (0.83 g/d) for 12 mo.The clinical symptoms,biochemical tests,and HCV RNA levels were assessed before,during,and after treatment.RESULTS:Fucoidan dose-dependently inhibited the expression of HCV replicon.At 8-10 mo of treatment with fucoidan,HCV RNA levels were significantly lower relative to the baseline.The same treatment also tended to lower serum alanine aminotransferase levels,and the latter correlated with HCV RNA levels.However,the improved laboratory tests did not translate into significant clinical improvement.Fucoidan had no serious adverse effects.CONCLUSION:Our findings suggest that fucoidan is safe and useful in the treatment of patients with HCV-related chronic liver diseases.Further controlled clinical trials are needed to confirm the present findings.

    Chronic infection by the hepatitis B virus (HBV) is a dynamic process that results from the interaction between HBV replication and the host's immune response. In accordance with the consensus document of the European Association for the Study of the Liver, treatment is not indicated for the immune tolerant and inactive carrier phases. However, there are situations in the 2 phases (which we could call gray areas of chronic HBV infection) in which the correct categorization of patients is not easy and in which the start of treatment can be proposed. In the immune tolerant phase, treatment could be indicated for health professionals whose responsibilities require their participation in invasive procedures. Treatment could also be indicated for pregnant women who are HBeAg-positive, ALT normal and have high HBV DNA values and for whom oral antiviral treatment is indicated during the last trimester of pregnancy to reduce the risk of vertical HBV transmission from mother to child. For patients in the inactive carrier phase who are HBeAg-negative with persistent normal ALT levels and HBV DNA ≥ 2000 IU/mL, the intensity of the hepatic lesion will determine the indication for treatment. If these patients already have established cirrhosis then treatment is indicated if the HBV DNA is detectable, regardless of the ALT level. Copyright © 2014 Elsevier España, S.L.

  5. Cytomegalovirus-Driven Adaptive-Like Natural Killer Cell Expansions Are Unaffected by Concurrent Chronic Hepatitis Virus Infections

    David F. G. Malone

    2017-05-01

    Full Text Available Adaptive-like expansions of natural killer (NK cell subsets are known to occur in response to human cytomegalovirus (CMV infection. These expansions are typically made up of NKG2C+ NK cells with particular killer-cell immunoglobulin-like receptor (KIR expression patterns. Such NK cell expansion patterns are also seen in patients with viral hepatitis infection. Yet, it is not known if the viral hepatitis infection promotes the appearance of such expansions or if effects are solely attributed to underlying CMV infection. In sizeable cohorts of CMV seropositive hepatitis B virus (HBV, hepatitis C virus (HCV, and hepatitis delta virus (HDV infected patients, we analyzed NK cells for expression of NKG2A, NKG2C, CD57, and inhibitory KIRs to assess the appearance of NK cell expansions characteristic of what has been seen in CMV seropositive healthy individuals. Adaptive-like NK cell expansions observed in viral hepatitis patients were strongly associated with CMV seropositivity. The number of subjects with these expansions did not differ between CMV seropositive viral hepatitis patients and corresponding healthy controls. Hence, we conclude that adaptive-like NK cell expansions observed in HBV, HCV, and/or HDV infected individuals are not caused by the chronic hepatitis infections per se, but rather are a consequence of underlying CMV infection.

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

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

    Lamivudine resistance is associated with long-term monotherapy for chronic hepatitis B and can lead to potentially serious clinical consequences. Scant information exists regarding the influence of hepatitis B virus variants in the development of resistance. The present study was designed to identify factors predictive of lamivudine resistance, with a particular focus on the role of precore and basal core promoter variants in the setting of hepatitis B e antigen-negative disease. Eighty-five patients, representing four major genotypes, were followed prospectively on lamivudine therapy. Resistance was defined as an increase in viral load, with polymerase gene sequencing confirming a lamivudine resistance mutation. Median follow up was 19 months (6-54 months). The Cox proportional hazards model was used to determine variables independently predicting for the early onset of lamivudine resistance. The rate of lamivudine resistance was 6%, 31% and 51% at 12, 24 and 48 months, respectively. Multivariate analysis identified the precore variant, high baseline alanine aminotransferase (ALT), and persistent viremia (at 6 months) as independent predictors of the early development of lamivudine resistance, with rate ratios of 4.93 (95% confidence interval [CI]: 1.32-18.5), 1.22 (95%CI: 1.08-1.49), and 4.73 (95%CI: 1.49-15.0), respectively (P < 0.05). Female sex predicted early resistance (rate ratio 5.27 [95%CI: 1.23-22.5, P < 0.05]) although numbers were small (n = 12). Genotype did not influence treatment response nor time to onset of resistance. Patients with precore variant hepatitis B virus are likely to develop lamivudine resistance early and should be considered for alternate first-line monotherapy. In the future, combination antiviral therapy may limit the development of resistance.

    Full Text Available Aim: to analyze leptin and adiponectin serum levels in patients with chronic hepatitis C in comparison with metabolic syndrome components, biochemical features and stage of hepatitis.Materials and methods: In 93 patients with chronic HCV in age 20-55 with a few symptomatic HCV-infection and minimal liver fibrosis stage serum leptin and adiponectin was measured. Associations between leptin, adiponectin and metabolic abnormalities, biochemical features, and hepatic fibrosis were determined.Results: Abdominal obesity was revealed at 40% patients, overweight – at 41%, insulin resistance – at 36,6% cases. The leptin and adiponectin levels were within normal limits range at most patients. Patients with minimal liver fibrosis had higher index of leptin by comparison to patients with moderate and severe fibrosis (r= – 0,402, р= 0,018. In patients with HCV genotype 3a the adiponectin level was below, than in HCV genotype 1b. Patients with abdominal obesity and overweight had higher leptin and lower adiponectin indexes by comparison to patients without these metabolic abnormalities. Direct cross-correlation between the leptin level and body mass index (r=0,358, p=0,001, waist circumference (r=0,292, p=0,01; negative cross-correlation between the adiponectin level and body mass index (r=- 0,435, р <0,021, waist circumference (r=- 0,386, р =0,001 were displayed.Conclusion: Leptin and adiponectin blood levels in HCVpatientis associated with abdominal obesity and overweight. The connection of leptin level and liver fibrosis stage was revealed. Difference of adiponectin level in HCV-patients with 3a and 1b genotypes of virus was found.

    The association of NAFLD with chronic hepatitis C (CHC) has been extensively studied but little is known about its coexistence with chronic hepatitis B (CHB). To investigate the prevalence and determinants of steatosis and insulin resistance (IR) in CHB and its consequences on liver injury compared with CHC and NAFLD. Patients with CHB (N=110), CHC (N=111) and NAFLD (N=136) were evaluated by biomarkers of steatosis (SteatoTest>0.38 as a surrogate for steatosis >5%), IR (HOMA-IR>2.7 as a surrogate for IR) and fibrosis (FibroTest>0.48 as a surrogate for significant fibrosis, ≥F2). HOMA-IR gradually increased in CHB, CHC and NAFLD: 2.3±1.8; 3±2.6 and 3.8±2.7 (p5% was 21% (CHB), 43% (CHC) and 82% (NAFLD), (p<0.001). The prevalence of fibrosis≥F2 was 10% (CHB), 42% (CHC) and 21% (NAFLD), p<0.001. In CHB, IR was related to host and not viral factors. CHB patients with steatosis had higher BMI (29±5.7kg/m(2) vs. 24±4kg/m(2), p<0.001), waist circumference (96±14cm vs. 84±11cm, p=0.001) and HOMA-IR (3.9±2.6 vs. 1.8±1.2, p<0.001) than those without steatosis. HOMA-IR independently predicted steatosis in CHB (OR=1.9, 95% CI, 1.09-3.27, p<0.05) and CHC (OR=1.38; 95% CI, 1.07-1.78, p<0.02). In CHB, metabolic risk factors and HOMA-IR were not associated with significant fibrosis. HOMA-IR was an independent predictor of fibrosis in CHC. Steatosis may co-exist in CHB patients but with a lower prevalence than in CHC and NAFLD. In CHB steatosis is related to host and not viral factors, and is not associated with the severity of fibrosis. Copyright © 2014 European Federation of Internal Medicine. Published by Elsevier B.V.

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

Eighty five percent of the patients were clinically asymptomatic and their physical examinations sbowed unremarkable or minimal changes at the time of the liver biopsy Liver function tests tended to present slight abnormalities, involving mild elevations of the activity of the aminotransferases and gamma-glutamil transferase levels. In spite of these mild abnormalities advanced chronic liver disease ivas histologically detected in eighty nine percent of the patients, mainly showing chronic active hepatitis. The most characteristic histological finding ivas an interlobular bile duct damage which correlated with the presence of tymphoid aggregates in the portal tracts and with the development of fibrosis.Realizou-se estudo clinico-patológico de 163 casos não tratados de hepatite crônica C. A maioria dos pacientes era clinicamente assintomática e seus exames físicos demonstravam alterações inespecíficas ou mínimas por ocasião da biópsia hepática. As provas de função hepática tendiam a apresentar alterações discretas, envolvendo especialmente os níveis séricos das aminotransferases e gama-glutamil transpeptidase. Apesar destas alterações discretas, detectou-se doença hepática crônica histologicamente avançada, consistindo principalmente de hepatite crônica ativa. O achado histológico mais característico foi lesão de dueto biliar interlobular, que se correlacionou com a presença de agregados linfóides nos tratos portais e com o desenvolvimento de fibrose.

    Full Text Available Rapid epidemiological transition globally has witnessed a rising prevalence of major chronic diseases such as hypertension, diabetes, hyperlipidaemia, obesity, chronic respiratory diseases and cancers over the past 30 years. In Malaysia, these conditions are commonly managed in primary care and published evidence has consistently shown suboptimal management and poor disease control. This in turn, has led to the massive burden of treating complications in secondary care, burden tothe patients and their families with regards to morbidity and premature death, and burden to the country with regards to premature loss of human capital. The crushing burden and escalating health care costs in managing chronic diseases pose a daunting challenge to our primary care system, as we remain traditionally oriented to care for acute, episodic illnesses. This paper re-examines the current evidence supporting the implementation of Wagner Chronic Care Model in primary careglobally; analyses the barriers of implementation of this model in the Malaysian private general practice through SWOT(strengths, weaknesses, opportunities and threats analysis; and discusses fundamental solutions needed to bridge the gap to achieve better outcomes.

    Alpha-fetoprotein is produced by a variety of tumors such as hepatocellular carcinoma, hepatoblastoma, and germ cell tumors of the ovary and testes. However, we present a case of significantly elevated serum alpha-fetoprotein without evidence of malignant disease in a patient who is a carrier of chronic hepatitis B. A 60-year-old Korean man presented with markedly increased alpha-fetoprotein (2350 ng/mL; normal 7 × 105 IU/mL). Our patient was diagnosed with acute exacerbation of chronic hepatitis B, and we presumed that this condition might be related to extremely elevated alpha-fetoprotein. When our patient was treated with entecavir, the serum alpha-fetoprotein level immediately decreased, in parallel with the hepatitis B virus deoxyribonucleic acid copy number. We report a rare case of extremely elevated alpha-fetoprotein due to acute exacerbation of chronic hepatitis B without any malignancy, and a decrease in this tumor marker simultaneous with a decrease in hepatitis B virus deoxyribonucleic acid copy number on entecavir treatment. This case report is important due to the rarity of the case; furthermore, it provides details of a diagnostic process for a variety of benign diseases and malignant tumors that should be considered in patients with elevated alpha-fetoprotein. Thus, we present a case report, along with a review, that will be helpful for diagnosis and treatment of patients with elevated alpha-fetoprotein.

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

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

    Objective: To evaluate the feasibility of treatment for rabbit model with hepatic cirrhosis by transplantation of autologous bone marrow-derived stem cells via the hepatic artery and evaluate the effect of hepatocyte growth-promoting factors (pHGF) in the treatment of stem cells transplantation to liver cirrhosis. To provide empirical study foundation for future clinical application. Methods: Chronic hepatic cirrhosis models of rabbits were developed by subcutaneous injection with 50% CCl 4 0.2 ml/kg. Twenty-five model rabbits were randomly divided into three experimental groups, stem cells transplant group (10), stem cells transplant + pHGF group (10) and control group (5). Autologous bone marrow was harvested from fibia of each rabbit, and stem cells were disassociated using density gradient centrifugation and transplanted into liver via the hepatic artery under fluoroscopic guidance. In the stem cells transplant + pHGF group, the hepatocyte growth-promoting factor was given via intravenous injection with 2 mg/kg every other day for 20 days. Liver function tests were monitored at 4, 8,12 weeks intervals and histopathologic examinations were performed at 12 weeks following transplantation. The data were analyzed using analysis of variance Results: Following transplantation of stern cells, the liver function of rabbits improved gradually. Twelve weeks after transplantation, the activity of ALT and AST decreased from (73.0±10.6) U/L and (152.4± 22.8) U/L to (48.0±1.0) U/L and (86.7±2.1) U/L respectively; and the level of ALB and PTA increased from (27.5±1.8) g/L and 28.3% to (33.2±0.5) g/L and 44.1% respectively. The changes did not have statistically significant difference when compared to the control group (P>0.05). However, in the stem cellstransplant + pHGF group, the activity of ALT and AST decreased to (43.3±0.6) U/L and (78.7±4.0) U/L respectively and the level of ALB and PTA increased to (35.7±0.4) g/L and 50.5% respectively. The difference was

    Exposure to other risk factors is an important consideration in assessing the role played by radiation in producing disease. A cross-sectional study of atomic-bomb survivors suggested an interaction between whole-body radiation exposure and chronic hepatitis-C viral (HCV) infection in the etiology of chronic liver disease (chronic hepatitis and cirrhosis), but did not allow determination of the joint-effect mechanism. Different estimates of probability of causation (POC) conditional on HCV status resulted from additive and multiplicative models. We therefore estimated the risk for radiation conditional on HCV status using a more general, mixture model that does not require choosing between additivity or multiplicativity, or deciding whether there is interaction, in the face of the large uncertainty. The results support the conclusion that POC increases with radiation dose in persons without HCV infection, but are inconclusive regarding individuals with HCV infection, the lower confidence bound on estimated POC for radiation with HCV infection being zero over the entire dose range. Although the mixture model may not reflect the true joint-effect mechanism, it avoids restrictive model assumptions that cannot be validated using the available data yet have a profound influence on estimated POC. These considerations apply more generally, given that the additive and multiplicative models are often used in POC related work. We therefore consider that an empirical approach may be preferable to assuming a specific mechanistic model for estimating POC in epidemiological studies where the joint-effect mechanism is in doubt.

    Pregnane X receptor (PXR) is a nuclear receptor that regulates cytochrome P450 3A (CYP3A) gene transcription in a ligand-dependent manner. Ethanol has been reported to be either an inducer or an inhibitor of CYP3A expression. In this study, we investigated the effects of chronic ethanol exposure on PXR and P450 3A11 gene expression in mouse liver. Female ICR mice were administered by gavage with different doses (1000, 2000 and 4000 mg/kg) of ethanol for up to 5 weeks. Hepatic PXR and P450 3A11 mRNA levels were measured using RT-PCR. Erythromycin N-demethylase (ERND) activity was used as an indicator of CYP3A protein expression. Results showed that chronic ethanol exposure markedly decreased hepatic PXR and P450 3A11 mRNA levels. Consistent with downregulation of P450 3A11 mRNA, chronic ethanol exposure significantly decreased ERND activity in a dose-dependent manner. Additional experiment showed that chronic ethanol exposure significantly increased plasma endotoxin level and hepatic CD14 and TLR-4 mRNA expression, all of which were blocked by elimination of Gram-negative bacteria and endotoxin with antibiotics. Correspondingly, pretreatment with antibiotics reversed the downregulation of PXR and P450 3A11 mRNA expression and ERND activity in mouse liver. Furthermore, the downregulation of hepatic PXR and P450 3A11 mRNA expression was significantly attenuated in mice pretreated with GdCl 3 , a selective Kupffer cell toxicant. GdCl 3 pretreatment also significantly attenuated chronically ethanol-induced decrease in ERND activity. These results indicated that activation of Kupffer cells by gut-derived endotoxin contributes to downregulation of hepatic PXR and P450 3A11 expression during chronic alcohol intoxication

    Injection drug users are at high risk for chronic hepatitis C virus infection (CHC). Opioid maintenance treatment (OMT) offers a unique opportunity to screen for CHC. This study proposed the hypothesis that a general practitioner (GP) with special interest in addiction medicine can achieve CHC screening rates comparable to specialized centres and aimed to investigate determinants for a successful CHC case finding in a primary care setting. Retrospective medical record analysis of 387 patients who received opioid maintenance therapy between 1 January 2002 and 31 May 2008 in a general practice in Zurich, Switzerland. Successful CHC assessment was defined as performance of hepatitis C virus (HCV) serology with consecutive polymerase chain reaction-based RNA and genotype recordings. The association between screening success and patient characteristics was assessed using multiple logistic regression. findings: Median (interquartile range) age and duration of OMT of the 387 (268 males) patients was 38.5 (33.6-44.5) years and 34 (11.3-68.0) months, respectively. Fourteen patients (3.6%) denied HCV testing and informed consent about screening was missing in 13 patients (3.4%). In 327 of 360 patients (90.8%) with informed consent a successful CHC assessment has been performed. Screening for HCV antibodies was positive in 136 cases (41.6%) and in 86 of them (63.2%) a CHC was present. The duration of OMT was an independent determinant of a successful CHC assessment. In addicted patients a high CHC assessment rate in a primary care setting in Switzerland is feasible and opioid substitution provides an optimal framework.

    The article presents the results of analysis of the frequency of detection of cryoglobulinemic syndrome (CGS) and insulin resistance (IR) in patients with HCV-associated liver cirrhosis (LC) depending on its stage. There were also evaluated clinical and laboratory features of the disease. The study involved 72 patients with chronic hepatitis C who were divided into 3 main groups according to the presence of LC. The I group included 32 patients with chronic hepatitis C without LC. The II group consisted of 19 patients with compensated HCV-associated LC and III group included 21 patients with decompensated LC. It was shown that terminal stages of the LC (class B-C by Child-Pugh) are characterized by more frequent presence of IR and CGS with more severe clinical picture, which may be caused not only by the influence of the hepatitis C virus (HCV), but also by the progression of LC.

    Objective: To explore the changes of serum HA, PCIII and ADA levels in patients with chronic hepatitis C. Methods: Serum HA, PCIII and ADA levels were detected with RIA in 42 cases with chronic hepatitis C and 35 controls. Results: The levels of serum HA, PC III and ADA in the patients were significantly higher than those in controls (P<0.01). Serum HA, PC m and ADA levels were positive correlated (r=0.6178, 0.6211, P<0.01). Conclusion: The results suggested the serum HA, PC m and ADA levels can reflect the degree of hepatic injury in the patients with cirrhosis, detection of serum HA, PC m and ADA levels is helpful in estimating the status of the disease.

    Objective: To discuss the feasibility of CT-guided percutaneous radiofrequency ablation (RFA) of liver malignancies located in unusual regions under general anesthesia, and to assess its clinical value. Methods: Eighteen patients with a total of 26 malignant hepatic lesions were enrolled in this study. The lesions were located at diaphragmatic surface, hepatic hilum, hepatic subcapsular site,side of inferior vena cava, side of gallbladder or near by colon. Transcatheter arterial chemoembolization was performed in all patients, which was followed by CT-guided percutaneous RFA under general anesthesia. The time used for puncturing and the time used for putting the needles to the scheduled sites were recorded. A follow-up for 115 months was conducted. The complications and the therapeutic results were observed. Results: For all patients,the procedure of puncture and needle placement was completed in 1-3 minutes. A total of 35 RFA procedures were conducted for 26 lesions. No severe complications occurred. Complete necrosis was observed in 20 tumors and partial necrosis in 6 tumors. Conclusion: The result of this study indicates that CT-guided percutaneous RFA under general anesthesia is a feasible technique for the treatment of liver malignancies located at unusual regions. This technique is very helpful for reducing the manipulating difficulty and lowing the complication risk of RFA procedures. (authors)

    Full Text Available Objectives: Evaluating the effectiveness of 2 therapeutic schemes for chronic hepatitis C (genotype 6 which combined sofosbuvir and ribavirin, one of them also included pegylated interferon. Materials and methods: The study included 110 patients with chronic hepatitis C (genotype 6, who have undergone antiviral therapy (HTP in Hepatology Clinic inHo Chi Minh City,Vietnamfrom November 2015 to July 2016. 24 patients were treated by Pegylated interferon alfa-2a, ribavirin and sofosbuvir for 12 weeks, 86 patients – by sofosbuvir and ribavirin for 24 weeks. Non-interferon regimen was administered primarily to patients with contraindications to the use of interferon. To monitor the effectiveness of antiviral therapy, quantification of HCV RNA in serum was performed by PCR prior to treatment, at 4th, 12th or 24th week (depending on the observation group from the starting of treatment and at 12th, 24th week after completion of treatment. Results: All patients, who were treated with pegylated interferon, ribavirin and sofosbuvir, completed the full course of treatment and 100% of them are registered with sustained virological response at 12th and 24th week after the end of antiviral therapy (SVR-12 and SVR-24, respectively. In the group of patients, who treated with ribavirin and sofosbuvir, 97,7% of patients completed full course of treatment (SVR-12 was registered in 93% of patients, and SVR-24 – in 91,9% of patients. Of 75 patients without a history of HCC, SVR24 was registered in 74 people (98,7%, of 11 patients with HCC – in 5 patients (45,5%. SVR-24 was registered in 98% of patients with cirrhosis (F4 without HCC. Conclusion: The results can serve as a justification for the use of these schemes of antiviral therapy for special groups of patients and/or conditions when it is impossible to follow the latest recommendations, which will help to expand the access of patients to effective antiviral therapy for chronic hepatitis C.

    Full Text Available Background: According to World Health Organization (WHO report about 400 million people are chronically infected with hepatitis B virus (HBV. Host immune responses which are mainly controlled by cytokines, can be either effective in disease progression or control the infection. Interleukin-27 (IL-27 is a pro-inflammatory cytokine which promotes Th1 responses. Genetic variations (e.g. single nucleotide polymorphisms [SNPs] can affect the product or activity of IL-27 gene. The aim of present study was to determine the association between IL-27 rs153109 and chronic HBV infection among the Iranian population. Materials and Methods: In this study chronic HBV patients (n=120, Anti-HBc Ab positive and HBsAg positive for more than 6 months and controls (n=120 from healthy individuals referred to Tehran Taleghani hospital (2013-2014 were studied. Genotypes of IL-27 gene polymorphism were detected by PCR-RFLP. DNA sequencing was applied on 10% of samples to validate the genotyping results. The studied variables were polymorphism genotypes/alleles, clinical status, age and gender. Results: Results showed no statistically significant difference for patients and control groups neither in genotype frequencies of AA among the chronic group (30% compared to healthy controls (32.5% (P=0.368; nor in allele frequency A 60.4% for patients against A 59.2% in control groups (P=0.780. Conclusion: Despite the importance of IL-27 in the immune response, the findings of this study suggests that genetic variants of IL-27 SNP 153109A/G were not associated with susceptibility to the chronic infection of HBV.

    Professional societies recommend hepatitis A and hepatitis B immunization for individuals with chronic liver disease (CLD), but the degree of implementation is unknown. Data were obtained from the National Health and Nutrition Examination Surveys (NHANES) conducted in 1999-2008. For the entire study population and for those with CLD and diabetes, we determined the rates and independent predictors of history of hepatitis A and hepatitis B (HepA and HepB) vaccinations, of their effectiveness, and of seroprevalence of hepatitis A antibody and anti-HB surface antibody. In total, 24,871 participants from NHANES were included: 14,886 (1999-2004) and 9,985 (2005-2008). Of these individuals, 14.0% had CLD and 8.6% had diabetes. During the study period, HepA vaccination in CLD increased from 13.3% ± 1.0% to 20.0% ± 1.5%, HepB vaccination increased from 23.4% ± 1.2% to 32.1% ± 1.5%. Of subtypes of CLD, HepA vaccination rates increased only in nonalcoholic fatty liver disease (NAFLD), whereas HepB vaccination increased for patients with hepatitis C and nonalcoholic fatty liver disease. In the diabetic cohort, HepA vaccination rates increased from 9.3% ± 1.1% to 15.4% ± 1.7% and HepB rates increased from 15.2% ± 1.5% to 22.4% ± 1.7%. All changes were similar to those observed in the general population. The quality measure (QM) for HepA in the general population decreased from 44.4% ± 1.2% in 1999-2004 to 41.7% ± 1.9% in 2005-2008, and similar changes were noted for all subcohorts. On the other hand, QM for HepB increased from 31.7% ± 0.9% to 40.7% ± 1.0% in the population, whereas no changes in QM were noted in any diagnostic cohort except for NAFLD. Although vaccination rates in CLD and diabetic cohorts are increasing, they remain low. Given the public health implications of acute hepatitis A and hepatitis B in patients with CLD, better implementation of the vaccination recommendations for these populations is warranted.

MethodsA total of 102 CHB patients who were treated in Department of Infectious Diseases, Nanfang Hospital, Southern Medical University from March 2010 to July 2014 were enrolled and divided into continuous treatment group (54 patients and drug withdrawal group (48 patients. The 36-item short-form health survey (SF-36 was used to measure QoL. The patients in the treatment group were evaluated before treatment and at 96 weeks of treatment, and those in the drug withdrawal group were evaluated at the time of drug withdrawal and at 48 weeks after drug withdrawal. The t-test was used for comparison of continuous data between groups, and the chi-square test was used for comparison of categorical data between groups. The logistic regression analysis was performed for univariate and multivariate analyses. ResultsCompared with before treatment, the continuous treatment group had significant increases in the scores on the domains of physiological function, role physical, bodily pain, and general health after 96 weeks of antiviral therapy (physiological function: 94.91±7.11 vs 92.13±10.58, t=-2.924,P<0.05; role physical: 81.94±24.96 vs 71.76±34.01, t=-2.623,P<0.05; bodily pain: 87.72±8.64 vs 82.85±12.88, t=-3.576,P<0.05; general health: 59.63±1459 vs 53.52±16.79, t=-3.786,P<0.05. As for psychological quality, the continuous treatment group had a significant increase in the subscale of mental health (67.30±18.94 vs 75.56±15.53, t=-3.883,P<0.001, while there were no significant improvements in other subscales. At 48 weeks after drug withdrawal, the drug withdrawal group had significant increases in role physical (84.20±18.97 vs 72.49±24.38, t=-2.768,P<0.05, general health (69.28±22.94 vs 56.41±18.27, t=-3.206,P<0.05, and mental health (75.02±16.03 vs

    Hepatic stellate cells play a crucial role in the pathogenesis of hepatic fibrosis. Thus, pharmacological inhibition of pro-fibrotic activities of these cells might lead to an effective therapy for this disease. Among the potent anti-fibrotics, interferon gamma (IFNγ), a proinflammatory cytokine, is highly efficacious but it failed in clinical trials due to the poor efficacy and multiple adverse effects attributed to the ubiquitous IFNγ receptor (IFNγR) expression. To resolve these drawbacks, we chemically synthesized a chimeric molecule containing (a) IFNγ signaling peptide (IFNγ peptidomimetic, mimγ) that retains the agonistic activities of IFNγ but lacks an extracellular receptor recognition sequence for IFNγR; coupled via heterobifunctional PEG linker to (b) bicyclic platelet derived growth factor beta receptor (PDGFβR)-binding peptide (BiPPB) to induce internalization into the stellate cells that express PDGFβR. The synthesized targeted IFNγ peptidomimetic (mimγ-BiPPB) was extensively investigated for its anti-fibrotic and adverse effects in acute and chronic CCl4-induced liver fibrosis models in mice. Treatment with mimγ-BiPPB, after the onset of disease, markedly inhibited both early and established hepatic fibrosis as reflected by a reduced intrahepatic α-SMA, desmin and collagen-I mRNA expression and protein levels. While untargeted mimγ and BiPPB had no effect, and native IFNγ only induced a moderate reduction. Additionally, no off-target effects, e.g. systemic inflammation, were found with mimγ-BiPPB, which were substantially observed in mice treated with native IFNγ. The present study highlights the beneficial effects of a novel BiPPB mediated cell-specific targeting of IFNγ peptidomimetic to the disease-inducing cells and therefore represents a highly potential therapeutic approach to treat fibrotic diseases.

    Paclobutrazol (PBZ) is a triazole-containing fungicide which is widely used in agriculture. Acute toxicity can follow its extensive use but it is generally weaker than traditional pesticides such as organochlorine and organophosphorus. However, its adverse effects on aquatic organisms need to be investigated. This study was conducted to investigate the effect of PBZ exposure on the hepatic lipid metabolism of Sebastiscus marmoratus. After PBZ exposure for 50 days, hepatic lipid droplets were enlarged and the hepatic total lipid, triglyceride, total cholesterol and free fatty acid content had increased in a dose dependent manner compared to the control. The mRNA expression of lipid metabolism associated genes such as peroxisome proliferator-activated receptors (PPARs), androgen receptor, acetyl-CoA carboxylase 1, fatty acid synthesis, fatty acid bing protein 4, liver X receptor {alpha} (LXR{alpha}) and stearoyl-CoA desaturase were up-regulated by PBZ exposure. These results indicated that triazole-containing fungicides might affect the metabolism and health of fish via the multi-signal pathways of nuclear receptors such as PPARs and LXR.

    Objective: To investigate the value of the MSCT liver perfusion imaging parameters in the evaluation of the chronic hepatic fibrosis and cirrhosis. Methods: Liver CT perfusion (CTP) was performed in 107 participants,including 31 patients with mild hepatic fibrosis (S1, S2), 34 patients with severe hepatic fibrosis (S3, S4) and early stage of hepatic cirrhosis which conformed by liver pathologic biopsy, 42 patients with hepatic cirrhosis who had typical clinical and image signs, and 30 healthy subjects as control group. The data of CTP (HAP, PVP, LTP, HPI and TTP) at different stages were obtained with Body perfect CT-syngo CT2007A and control study with histopathologic stage. Compared the study index by the one-way ANOVA analysis. Used Spearman rank correlation to analysis the relationship between liver perfusion imaging parameters and the degrees of the chronic hepatic fibrosis. Used Logistic regression to analysis the maximum regression coefficient among the liver perfusion imaging parameters, which affected the histopathologic stage mostly. Results: In the subgroups of the chronic hepatic fibrosis S1, S2, S3, S4 to the hepatic cirrhosis,HAP values was (28.9 ±8.6), (24.6 ±2.4), (29.2 ±2.3) and (38.9 ± 7.0) ml · 100 ml -1 · min -1 , respectively. HAP decreased firstly,then increased. Statistic analysis showed the difference of HAP between later-stage cirrhosis and other groups (F=40.26, P<0.01). PVP values of above subgroups was (111.3 ± 18.1), (92.9 ±5.3), (73.0 ±9.0) and (54.1 ± 13.8) ml · 100 ml -1 ·min -1 , respectively. TLP values of above subgroups was (140.2 ± 25.9), (117.1 ± 4.5), (102.3 ± 8.7)and (93.0 ± 11.8) ml · 100 ml -1 ·min -1 , respectively. The difference of PVP, TLP among each subgroup was significant (F=136.79, 67.40, respectively, P<0.01). HPI values of above subgroups was (20.4 ± 2.6)%, (21.0 ±2.1)%, (28.5 ±3.1)% and (42.6± 11.1)%, respectively. TTP values of above subgroups was (123.7±22.2), (137.1 ±27.1), (145.0 ±28

    To evaluate the impact of routine hepatitis B (HB) vaccination on the prevalence of chronic hepatitis B virus (HBV) infection among children in Pacific Island countries where HBV infection was highly endemic, we conducted HB serosurveys during 2000 to 2007 among women of childbearing age born before implementation of HB vaccination and among children born after its implementation. Serum specimens were collected from children aged 2 to 6 years and their mothers in Chuuk, Federated States of Micronesia in 2000, children aged 2 to 9 years and their mothers in Pohnpei, Federated States of Micronesia in 2005, and 5- to 9-year-old children and prenatal clinic patients in 2007 in Republic of the Marshall Islands (RMI). Specimens were tested for HB surface antigen (HBsAg) and antibodies to HB core antigen (total anti-HBc). HB vaccination coverage was determined from health department vaccination registries. We defined chronic HBV infection as the presence of HBsAg. Birthdose and 3 dose HB vaccination coverage was 48% and 87%, respectively, in Chuuk, 87% and 90% in Pohnpei, and 49% and 93% in RMI. Chronic HBV infection prevalence among children was 2.5% (9/362) in Chuuk, 1.5% (7/478) in Pohnpei and 1.8% (6/331) in RMI. Chronic HBV infection prevalence among women was 9.2% (21/229) in Chuuk, 4.4% (10/229) in Pohnpei, and 9.5% (11/116) in RMI. Hepatitis B vaccination has resulted in a substantial decline in chronic infection in children in the Pacific Islands. HB vaccine effectiveness is high in this region, despite challenges in providing HB vaccine at birth and completing vaccination series on schedule.

  4. The role of fluoxetine in antiviral therapy for chronic hepatitis C

    Full Text Available More than 20% of chronic hepatitis C (CHC patients receiving the antiviral therapy with interferonα(IFNα experience depression, and fluoxetine is often used to alleviate this symptom. Fluoxetine has anti-inflammatory properties and can change the synthesis of liver lipids, but its influence on antiviral therapy for CHC and related mechanism remain unknown. Recent studies show that fluoxetine can inhibit hepatitis C virus (HCV infection and reduce the production of reactive oxygen species (ROS and lipid accumulation in Huh7.5 cells; in addition, it can promote the antiviral effect mediated by IFNα through activating STAT1 and JNK signaling pathways and thus reduce HCV viral load and the level of alanine aminotransferase in CHC patients. Fluoxetine elevates PPAR response element activity in CHC patients, and its inhibitory effect on HCV infection and lipid accumulation were partly reversed by antagonists including PPARβ/γ, suggesting that fluoxetine inhibits HCV infection, ROS production, and lipid accumulation through regulating PPARβ/γ and JNK/STAT pathways.

    The preliminary question regarding the clinical issue of the antiviral therapy in the HCV related chronic hepatitis patients is: is it mandatory the research for the autoantibodies in the eligible patients for the antiviral treatment? This issue is of particular interest at the light of the the reported cases of HCV positive patients with positivity for liver kidney microsome type 1 antibody who developed a hepatitic flare during the antiviral treatment. The data from literature about the efficacy and safety on the antiviral treatment in patients with autoantibodies are few and controversial, particularly if the ones regarding antiviral drugs and more recent treatment regimens are taking into account (peg-interferon, combined therapy of interferon and ribavirin). Large and prospective studies are needed for a thorough evaluation about the potential impact of autoantibodies reactivity on the therapeutic outcome. To date, it must be confirmed that a strict monitoring of hepatic parameters is to recommend during the whole treatment phase. This in the light of a potential appearance of significant flares of aminotransferases, particularly in subjects with anti LKM-1 autoantibodies, during interferon therapy.

    To detect the ratio of natural killer (NK)/natural killer T (NKT) cells in peripheral blood, the levels of NKG2D/NKG2A, interferon γ (IFN-γ) and tumor necrosis factor α (TNF-α) in patients with chronic hepatitis B (CHB). Peripheral blood mononuclear cells (PBMCs) were harvested from CHB patients. The ratio of NK/NKT cells in PBMCs and the levels of NKG2D and NKG2A were detected by flow cytometry. The expressions of intracellular IFN-γ and TNF-α were analyzed by flow cytometry after the treatment with phorbol 12-myristate 13-acetate (PMA), brefeldin A (BFA) or ionomycin in vitro. The comparison between two groups was performed by independent sample t-test. The relationship of each index to hepatitis B virus load and serum alanine aminotransferase was analyzed by Pearson correlation analysis. Compared with healthy controls, CHB patients presented with significantly decreased peripheral blood NK/NKT cell ratio and significantly elevated proportions of NKG2A+ NK and NKG2A+NKT cells, and after the treatment with PMA/BFA/ionomycin, IFN-γ+ NK and IFN-γ+ NKT cells were significantly reduced in CHB patients. NK and NKT cells showed a reduced ratio, disordered receptor expressions and decreased cytokine secretion capacity in CHB patients.

    Liver fibrosis is an important prognostic factor for chronic hepatitis B (CHB), and accurate evaluation of the stage of liver fibrosis is crucial in establishing management strategies. While liver biopsy is still considered the gold standard for staging liver fibrosis or cirrhosis, transient elastography (TE), a noninvasive means of assessing liver fibrosis, has come to play an increasing role in this process. After extensive validation, TE is now regarded as a reliable surrogate maker for grading the severity of liver fibrosis in CHB patients. It can detect the extent of fibrosis in a patient and can also be used to evaluate longitudinal changes in liver fibrosis over time with or without interventional management, such as antiviral therapy. However, several confounders hinder the effective assessment of liver fibrosis using TE, such as extensive liver necroinflammation, hepatic congestion, and cholestasis. TE has limited use in obese patients or patients with ascites. Although TE has several limitations, due to its accessibility and safety, it is a valuable tool for the initial evaluation and follow-up in patients with CH.

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

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

    Purpose. To evaluate the efficacy of embolization of portal-systemic shunts in cirrhotic patients with chronic recurrent hepatic encephalopathy (CRHE). Methods. Seven cirrhotic patients with CRHE refractory to medical treatment (3 men and 4 women, mean age 66 years) were studied. Five patients had splenorenal shunts, 1 had a gastrorenal shunt, and 1 had an intrahepatic portal vein-hepatic vein shunt. Shunt embolization was performed using stainless steel coils, with a percutaneous transhepatic portal vein approach in 4 patients and a transrenal vein approach in 3 patients. Results. After embolization, the shunt disappeared in 4 patients on either ultrasound pulsed Doppler monitoring or portography. Complications observed in the 7 patients were fever, transient pleural effusion, ascites, and mild esophageal varices. For 3-6 months after embolization, the 4 patients whose shunts disappeared showed minimal or no reappearance of a shunt, and had no recurrence of encephalopathy. The serum ammonia levels decreased and electroencephalograms also improved. One of the 4 patients, who developed mild esophageal varices, required no treatment. Treatment was effective in 3 of the 4 patients (75%) who underwent embolization via a transhepatic portal vein. Conclusion. Transvascular embolization of shunts improved the outcome in 4 of 7 patients. The most effective embolization was achieved via the percutaneous transhepatic portal vein approach

    Anti-idiotypic antibodies (anti-Id) against anti-HBs were found in the sera of patients with chronic hepatitis type B. Anti-idiotypic antibodies were detected by an enzyme-linked immunosorbent assay using horseradish peroxidase conjugated mouse monoclonal anti-HBs. Ten of 72 HBsAg positive sera contained anti-Id (13.9%). The prevalence of anti-Id did not appear to correlate with HBeAg/anti-HBe system. However, HB virus specific DNA polymerase activity was significantly higher in anti-Id positive sera. In the sera obtained from the patients treated with predonisolone before, anti-Id positive rate was higher than that in the patients without a history of predonisolone therapy. These results suggest that anti-Id may be related to the immunoregulatory mechanism of HB virus replication.

    A middle-aged man was admitted to the ED because of nausea and vomiting, abdominal distention and fainting. A blood analysis revealed high levels of serum amylase and lipase, confirming a diagnosis of acute pancreatitis. The history showed that the patient had self-administered a single dose of pegylated interferon alfa-2b and ribavirin daily for 7 days for chronic hepatitis C. The medications were stopped and his condition gradually improved. In agreement with the literature and the Naranjo algorythm result, pegylated interferon alfa-2b is associated with acute pancreatitis. Identification of a few signs and symptoms is the first 'signal' in preventing a serious drug-induced adverse event.

    A 55-year-old Egyptian woman with chronic hepatitis C undergoing treatment with pegylated interferon (Peg-IFN) alfa-2a plus ribavirin was referred to our hospital on November 2010 with prolonged easy fatigability and an attack of syncope; she had no prior history of autoimmune disorders or allergy. Laboratory investigations documented the presence of Peg-IFN induced autoimmune haemolytic anaemia and autoimmune thyroiditis. Intravenous γ globulin (IVGG) failed to correct the autoimmune process; on the other hand steroid therapy dramatically corrected both haematological and thyroid values, and step down the immune process. Our report indicated that Peg-IFN de novo-induce autoimmune haemolysis, documenting a previous report. IVGG failed to step down the immune process in our case.

    Full Text Available Background Hepatitis B is one of the most common chronic viral infections worldwide, especially in developing countries. The insufficient treatment of the disease increases the risk of cirrhosis and hepatocellular carcinoma, which impose heavy costs to the patient and the society. Different studies evaluated several protocols for the treatment of the disease. Objectives The aim of this study was to evaluate the response rate of the different treatments in patients with chronic hepatitis B (CHB. Patients and Methods In a cross-sectional study, 89 patients with CHB who were referred to Infectious Diseases Clinics during 2004 to 2009 were studied. Serological and biochemical outcomes to the different treatments were evaluated. The data were analyzed by SPSS 16. Results CHB was more frequent in men (74.2% than women (25.8%. The mean age of the patients was 36 ± 1.36 years. Fifty-three patients (59.6% had active CHB while 36 (40.4% were asymptomatic carriers. Serologic and biochemical responses to the treatment were 50% and 69.44%, respectively. However, 50% of the patients with positive HBeAg showed serologic response to the treatment, 37.5% showed HBeAb as well as reduced amounts of HBeAg, and 12.5% just showed reduced amounts of HBeAg. Patients treated by lamivudine showed the highest serologic response rate (75%. Conclusions Serologic and biochemical response to the different treatments in the patients were better than other similar studies. Besides, it is recommended to begin antiviral therapy against CHB infection with lamivudine alone as a first-line therapy.

    Full Text Available Two out of six strategic axes of pharmaceutical care in our hospital are quality and safety of care, and the incorporation of information technologies. Based on this, an information system was developed in the outpatient setting for pharmaceutical care of patients with chronic hepatitis C, SiMON-VC, which would improve the quality and safety of their pharmacotherapy. The objective of this paper is to describe requirements, structure and features of Si- MON-VC. Requirements demanded were that the information system would enter automatically all critical data from electronic clinical records at each of the visits to the Outpatient Pharmacy Unit, allowing the generation of events and alerts, documenting the pharmaceutical care provided, and allowing the use of data for research purposes. In order to meet these requirements, 5 sections were structured for each patient in SiMON-VC: Main Record, Events, Notes, Monitoring Graphs and Tables, and Follow-up. Each section presents a number of tabs with those coded data needed to monitor patients in the outpatient unit. The system automatically generates alerts for assisted prescription validation, efficacy and safety of using antivirals for the treatment of this disease. It features a completely versatile Indicator Control Panel, where temporary monitoring standards and alerts can be set. It allows the generation of reports, and their export to the electronic clinical record. It also allows data to be exported to the usual operating systems, through Big Data and Business Intelligence. Summing up, we can state that SiMON-VC improves the quality of pharmaceutical care provided in the outpatient pharmacy unit to patients with chronic hepatitis C, increasing the safety of antiviral therapy.

    Hepatitis C virus infection evolves into chronic progressive liver disease in a significant percentage of patients. Monocytes constitute a diverse group of myeloid cells that mediate innate and adaptive immune response. In addition to proinflammatory CD16+ monocytes, a Tie-2+ subgroup - Tie-2 expressing monocytes (TEMs) - that has robust proangiogenic potential has been recently defined. To study the heterogeneity of peripheral blood monocytes in chronic hepatitis C (CHC) patients and to examine their proposed pathophysiological roles on disease progression and response to antiviral therapy. We studied CD16+ and Tie-2+ peripheral monocyte subpopulations in 21 healthy subjects and 39 CHC patients in various stages of disease and responses to antiviral treatment using flow cytometry. Expression profiles of proangiogenic and tissue remodelling factors in monocyte supernatants were measured using ELISA and protein arrays. Intrahepatic expression of CD14, CD31 and Tie-2 was analysed using immunofluorescence. Increases of certain peripheral monocyte subsets were observed in the blood of CHC patients, wherein those cells with proinflammatory (CD16+) or proangiogenic (TEMs) potential expanded (P TEMs were significantly increased in nonresponders, particularly those with lower CD16 expression. In addition, many angiogenic factors were differentially expressed by peripheral monocytes from control or CHC patients, such as angiopoietin-1 and angiogenin (P TEMs were distinguished within portal infiltrates of CHC patients. These findings suggest for the first time the relevance of peripheral monocytes phenotypes for the achievement of response to treatment. Hence, the study of monocyte subset regulation might effect improved CHC prognoses and adjuvant therapies. © 2011 Blackwell Publishing Ltd.

    Hepatitis E infection is one of the most frequent causes of acute hepatitis in the world. Currently five human genotypes with different geographical distributions and distinct epidemiologic patterns are identified. In Slovakia, only rare cases of hepatitis E have been reported in past years. Because the most important risk factors associated with HEV infection include consumption of contaminated pork meat and poor hygienic standards, the aim of the study was to evaluate the prevalence of anti-HEV total antibodies and the main risk factors for HEV in the population living in separated and segregated Roma settlements ( n = 195), which represent places with increased risk of infection in Slovakia and to compare it with the prevalence in the general population ( n = 69). Of 264 respondents included in the study, 47 (17.8%) showed positivity for anti-HEV antibodies, 42 of whom were Roma (21.5%, n = 195) and 5 (7.2%, n = 69) non-Roma. The population living in Roma settlements lives in poorer conditions and are at higher risk of HEV in comparison to the general population. However, differences in living conditions within the settlements do not contributed to lower risk of HEV antibody prevalence between Roma living in settlements.

    Hepatitis C virus (HCV) causes a clinically important disease affecting 3% of the world population. HCV is a single-stranded, positive-sense RNA virus belonging to the genus Hepacivirus within the Flaviviridae family. The virus establishes a chronic infection in the face of an active host oxidative defence, thus adaptation to oxidative stress is key to virus survival. Being a small RNA virus with a limited genomic capacity, we speculate that HCV deploys a different strategy to evade host oxidative defence. Instead of counteracting oxidative stress, it utilizes oxidative stress to facilitate its own survival. Translation is the first step in the replication of a plus strand RNA virus so it would make sense if the virus can exploit the host oxidative defence in facilitating this very first step. This is particularly true when HCV utilizes an internal ribosome entry site element in translation, which is distinctive from that of cap-dependent translation of the vast majority of cellular genes, thus allowing selective translation of genes under conditions when global protein synthesis is compromised. Indeed, we were the first to show that HCV translation was stimulated by an important pro-oxidant-hydrogen peroxide in hepatocytes, suggesting that HCV is able to adapt to and utilize the host anti-viral response to facilitate its own translation thus allowing the virus to thrive under oxidative stress condition to establish chronicity. Understanding how HCV translation is regulated under oxidative stress condition will advance our knowledge on how HCV establishes chronicity. As chronicity is the initiator step in disease progression this will eventually lead to a better understanding of pathogenicity, which is particularly relevant to the development of anti-virals and improved treatments of HCV patients using anti-oxidants.

    AASLD and EASL guidelines recommend biannual hepatocellular carcinoma (HCC) screening for non-cirrhotic patients with chronic hepatitis B infection (HBV), yet there are no data estimating surveillance rates or factors associated with surveillance. We performed a retrospective cohort study of U.S. patients using the Truven Health Analytics databases from 2006-2010, and identified patients with non-cirrhotic chronic HBV. Surveillance patterns were characterized using categorical and continuous outcomes, with the continuous measure of the proportion of time “up-to-date” with surveillance (PUTDS), with the six-month interval following each ultrasound categorized as “up-to-date.” During a median follow-up of 26.0 (IQR: 16.2-40.0) months among 4,576 non-cirrhotic patients with chronic HBV (median age: 44 years, IQR: 36-52), only 306 (6.7%) had complete surveillance (one ultrasound every 6-month interval), 2,727 (59.6%) incomplete (≥1 ultrasound), and 1,543 (33.7%) none. The mean PUTDS was 0.34 ± 0.29, and the median was 0.32 (IQR: 0.03-0.52). In multinomial logistic regression models, patients diagnosed by a non-gastroenterologist were significantly less likely to have complete surveillance (psurveillance. Patients with HIV had an absolute decrease in the PUTDS of 0.24, while patients in less populated rural areas had an absolute decrease of 0.10. HCC surveillance rates in non-cirrhotic patients with chronic HBV in the United States are poor, and lower than reported rates of HCC surveillance in cirrhotic patients. PMID:25581816

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

    Purpose: When evaluating the efficacy of therapies for cirrhosis such as branched-chain amino acid (BCAA), knowledge of the natural history of hepatic functional reserve in patients with chronic liver disease is essential. However, biochemical tests such as serum albumin level and prothrombin time do not faithfully reflect hepatic functional reserves since they are affected 'by the blood product supplementation used for treatment. On the other hand, hepatic receptor imaging with Tc-99m DTPA-galactosyl human serum albumin (Tc-99m GSA) allows objective evaluation of hepatic functional reserve since it is not affected by blood preparations. This method allows hepatic functional reserve to be estimated quantitatively on the basis of the receptor index and index of blood clearance. The natural course of chronic liver diseases has been reported in terms of changes in liver histology and development of hepatocellular carcinoma. However, there has been no report on the natural course of changes in hepatic functional reserve in patients with chronic liver disease. We monitored hepatic functional reserve in patients with chronic hepatitis and cirrhosis using scintigraphy with Tc-99m GSA. Materials and Methods: A cross-sectional study was performed for all subjects who underwent scintigraphy with Tc-99m GSA at our hospital. Of these, 324 were patients with chronic liver disease (86 with chronic hepatitis and 226 with cirrhosis) diagnosed at our hospital by examination of liver specimens obtained by laparoscopy or needle biopsy performed under ultrasonic guidance and 12 were subjects found to have a healthy liver when examined during the same period. Moreover, we selected for a longitudinal study all patients with underlying hepatic viral infection, without hepatocellular carcinoma, not treated by interferon, and not treated surgically or by sclerotherapy for varices, who agreed to return after discharge to our outpatient clinic for monitoring and who gave informed consent to

    We studied a cohort of adult patients with chronic hepatitis B (CHB) infection, followed at a tertiary referral liver center in Germany over 12.5 years to analyze the clinical features and impact of management on disease progression and survival of CHB patients in general and of those with CHB and HCC in particular. We retrospectively evaluated the medical records of 242 adult (age ≥ 18 years) patients. CHB was defined as positive hepatitis B surface antigen (HBsAg) and/or HBV-DNA levels >10 IU/mL for at least 6 months. Patient demographics, HBV markers, antiviral treatment, laboratory parameters, liver imaging and histology were recorded for each visit. HCC patients were divided into two groups and separately analyzed (group 1: n = 24, HCC at first visit and group 2: n = 11, HCC during surveillance). The mean age was 44 years in CHB patients without HCC (63% male) and about 59 years in patients with HCC (77% male). Antiviral therapy was given to 59% of patients without HCC compared to only 25% in group 1 and 18% in group 2 with comparable median HBV DNA levels of approximately 36,000 IU/mL. There was no statistically significant difference concerning the HCC stages (Milan, UCSF, BCLC) at first diagnosis. Five-year survival was 19% in group 1 vs. 64% in group 2 (p = 0.019), with LTx performed in 12 vs. 45%, respectively. Surveillance of CHB patients did not result in early stage detection of HCC but in a higher likelihood to receive potentially curative treatments.

    This study aimed to describe the Health-related quality of life (HRQoL) outcomes for Korean chronic hepatitis C patients and to investigate the impact of patient and virus-related factors on HRQoL. HRQoL was assessed in 235 HCV-infected patients from 7 nationwide tertiary hospital, including those with liver cirrhosis and hepatocellular carcinoma (HCC), using the Shor-Form 36 (SF-36) version 2 and the European quality of life questionnaire-5 dimensions (EQ-5D-3L). The SF-36 physical (48.8±8.3) and mental (46.2±11.7) component summary scores of the HCV-infected patients were below normal limits. Of the eight domains, general health, vitality, and mental health tended to show low scores. Patients with decompensated cirrhosis had the lowest HRQoL, while HCC and chronic hepatitis patients had similar HRQoL results. The EQ-5D index was low (0.848±0.145) in the HCV infected patients. Multivariable analysis showed age ≤65 years, high monthly family income (>$2,641), low comorbidity score, and sustained virologic response (SVR) were independently associated with favorable HRQoL. HRQoL in Korean patients with chronic HCV infection was low and was affected by cirrhosis severity, SVR, and comorbidity as well as income, which had the strongest effect. Therefore, HRQoL may be improved by antiviral therapy with reasonable costs to prevent cirrhosis progression.

    To evaluate the value of noninvasive tools for diagnosis of hepatic steatosis in patients with chronic hepatitis B (CHB). Consecutive treatment-naïve patients with CHB with body mass index less than 30kg/m 2 who underwent liver biopsy, ultrasound and FibroScan ® were enrolled. The diagnostic performance of controlled attenuation parameter (CAP), hepatic steatosis index (HSI) and ultrasound for hepatic steatosis compared with liver biopsy was assessed. The areas under receiver operating characteristics curves (AUROCs) were calculated to determine the diagnostic efficacy, with comparisons using the DeLong test. CAP and HSI accuracies were significantly higher than that of ultrasound to detect patients with biopsy-proven mild steatosis (S1, 65.3%, 56.5%, respectively, vs. 17.7%, χ 2 =46.305, 31.736, both Psteatosis (92.3%, 100%, respectively, vs. 53.8%, χ 2 =4.887, 7.800, P=0.037, 0.007, respectively). Both CAP and HSI had lower underestimation rates of steatosis grade than ultrasound (12%, 14.8%, respectively, vs. 29.5%, χ 2 =9.765, 6.452; Phepatic steatosis than HSI and ultrasound in patients with CHB, but further studies are needed to reduce the overestimation rates.

    Objective: To determine the frequency of development of hepatocellular carcinoma in patients with chronic liver disease secondary to hepatitis C who had achieved sustained virological response with Interferon and Ribavirin therapy. Study Design: Retrospective descriptive study. Place and Duration of Study: Shifa International Hospital, Islamabad, Pakistan, from January 2007 to January 2012. Methodology: Hepatitis C related chronic liver disease patients who were treated with interferon and ribavirin, after they achieved sustained virological response, they were followed for a mean of 42 A+- 17 months. During this time, development of hepatocellular carcinoma was ascertained. All underwent surveillance with alpha-feto-protein and ultrasonography every 6 months. Results: Out of the 58 patients who had achieved sustained virological response, 3 developed hepatocellular carcinoma after a mean follow-up of 38 A+- 14 months. It was multifocal in 2 cases and was single lesion in the 3rd. Two patients ultimately died, one with upper GI bleeding and the other with hepatic encephalopathy, while 3rd patient with single lesion is still surviving. Conclusion: Three out of 58 patients of hepatitis C related chronic liver disease developed hepatocellular carcinoma during follow-up in patients who had achieved sustained virological response. These patients need closer follow-up, for development of complications, even if they have achieved sustained viral response. (author)

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

    Globally, More than 350 million individuals are chronically infected with hepatitis B virus (HBV), and >20 million of them are co-infected with hepatitis D virus (HDV). The aim of this study was to determine the pattern of HDV infection in patients with chronic hepatitis B in three main tertiary hospitals in Tripoli and Benghazi, Libya. This cross sectional and descriptive study was conducted on 162 patients with chronic hepatitis B positive for more than six months) who were followed up at hepatitis clinics of the three main tertiary hospitals in Tripoli city (88 patients from Tripoli Medical Centre and Tripoli Central Hospital) and Benghazi city (74 patients from Aljomhoria Hospital) during the period from January 2010 to June 2012. HBV and HDV markers were detected by enzyme linked fluorescent assay (ELFA) or enzyme-linked immunosorbent assay and HBV-DNA was quantified by real-time PCR techniques. The mean age of patients was 36,92 ± 15,35. One hundred and three (63.6%) of them were males and 59 (36,4%) were females. Four patients (2,5%) were tested positive for anti-HD antibodies, all of them have had clinical and/or histological diagnosis of cirrhosis. In multivariable regression analysis, age (p = .04), elevation of serum ALT (p = .03), elevation of serum AST (p = .04), and presence of cirrhosis (p = .003) were significantly related to HDV seropositivity. Although the study demonstrated that Libya has low to moderate prevalence of HDV (2,5%), it is important for policy makers and health care providers to continue the preventive measures for HDV spread, and HBV prevention program including utilization of HBV vaccine. Furthermore, it is imperative to screen chronic HBV patients for HDV for close observation for early diagnosis of subsequent development of liver cirrhosis. Moreover, further epidemiologic and genetic studies are needed to explore the trend for HDV infection in Libya. Copyright © 2017 Pan-Arab Association of Gastroenterology

    Anti-liver/kidney microsomal antibody type 1 (anti-LKM1), a serological marker of type 2 autoimmune hepatitis, is also detected in a small proportion of patients with hepatitis C. This study aimed to evaluate clinical features and effect of antiviral therapy in patients with hepatitis C who are anti-LKM1 positive. Sixty consecutive anti-LKM1 positive and 120 age and sex-matched anti-LKM1 negative chronic hepatitis C patients were assessed at diagnosis and during follow-up. Of these, 26 anti-LKM1 positive and 72 anti-LKM1 negative received antiviral therapy. Anti-LKM1 was detected by indirect immunofluorescence and immunoblot. Number of HCV-infected hepatocytes and intrahepatic CD8+ lymphocytes was determined by immunohistochemistry. At diagnosis anti-LKM1 positive patients had higher IgG levels and more intrahepatic CD8+ lymphocytes (p 0.022 and 0.046, respectively). Viral genotypes distribution and response to therapy were identical. Hepatic flares during antiviral treatment only occurred in a minority of patients in concomitance with anti-LKM1 positivity. Immune system activation is more pronounced in anti-LKM1 positive patients with hepatitis C, possibly representing the expression of autoimmune mechanisms of liver damage. Antiviral treatment is as beneficial in these patients as in anti-LKM1 negative patients, and the rare necroinflammatory flares are effectively controlled by corticosteroids, allowing subsequent resumption of antiviral therapy.

    We previously confirmed that rats overloaded with aluminum exhibited hepatic function damage and increased susceptibility to hepatic inflammation. However, the mechanism of liver toxicity by chronic aluminum overload is poorly understood. In this study, we investigated changes in the 5-lipoxygenase (5-LO) signaling pathway and its effect on liver injury in aluminum-overloaded rats. A rat hepatic injury model of chronic aluminum injury was established via the intragastric administration of aluminum gluconate (Al{sup 3+} 200 mg/kg per day, 5 days a week for 20 weeks). The 5-LO inhibitor, caffeic acid (10 and 30 mg/kg), was intragastrically administered 1 h after aluminum administration. Hematoxylin and eosin staining was used to visualize pathological changes in rat liver tissue. A series of biochemical indicators were measured with biochemistry assay or ELISAs. Immunochemistry and RT-PCR methods were used to detect 5-LO protein and mRNA expression in the liver, respectively. Caffeic acid administration protected livers against histopathological injury, decreased plasma ALT, AST, and ALP levels, decreased TNF-α, IL-6, IL-1β and LTs levels, increased the reactive oxygen species content, and down-regulated the mRNA and protein expressions of 5-LO in aluminum overloaded rats. Our results indicate that 5-lipoxygenase activation is mechanistically involved in chronic hepatic injury in a rat model of chronic aluminum overload exposure and that the 5-LO signaling pathway, which associated with inflammation and oxidative stress, is a potential therapeutic target for chronic non-infection liver diseases. - Highlights: • 5-LO signaling contributes to mechanisms of hepatotoxicity of aluminum overload. • Oxidative and inflammatory reaction involve in chonic aluminum hepatotoxicity. • 5-LO inhibitor has a protective effect on aluminum-overload liver injury. • 5-LO signaling is a potential therapeutic target for non-infection liver diseases.

    Metabolic changes are inextricably linked to chronic hepatitis C (CHC). Recently polymorphisms in the IFNL3 (IL28B) region have been shown to be strongly associated with spontaneous and treatment induced recovery from hepatitis C virus (HCV) infection. Further, circumstantial evidence suggests a link between IFNL3 single nucleotide polymorphisms and lipid metabolism, steatosis and insulin resistance in CHC. The emerging picture suggests that the responder genotypes of IFNL3 polymorphisms are associated with a higher serum lipid profile, and less frequent steatosis and insulin resistance. This review analyzes the current data regarding this interaction and its meaning for HCV pathogenesis and disease progression.

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

    Full Text Available Background: With the growing trend of unhealthy behaviors in the community, the likelihood of transmission of hepatitis B virus from infected people to society is increasing. So, early detection for preventing disease progression in patients and preventing the spread to the community has an important role. The aim of this study is assessment of risk factors in patients with chronic hepatitis B referred to Labbafi nejad’s Hospital hepatitis Clinic during 2012-2014.Materials and Methods: This cross-sectional study is done on 329 hepatitis B confirmed patients that were admitted to Labbafi nejad’s Hospital hepatitis Clinic 2012-15. Information was collected by interviewing patients by researcher-made questionnaire. Variables are, all risk factors for hepatitis B, respectively. Statistical analysis was performed by SPSS version 21. Average and frequency was used for descriptive and chi-square test was used for analysis.Results: 329 persons (59% males, 41%females with a mean age of 44/83 years. 33/7% of these individuals have been identified through routine screening. The frequency of exposure to risk factors in this study are as follows: Some groups, such as history of dentist visit (62.3%, major surgery (45.5% and hospitalization (54.7% had higher prevalence than other groups. There were no cases of hepatitis B in history of cosmetics and splice joint, common use of blades and razors, HCV disease in patients at the same time, Family history of HIV positive in patients and HIV disease in patients at the same time.Conclusion: It seems to be of great importance to pay more attention to certain jobs, lifestyles and cultural matters in Iran that predispose people to a number of risk factors so as to implement measures to control HBV spread. Also, given the high levels of hepatitis B infection among housewives (in this study, it seems that increased awareness and social - health education in order to avoid unprotected sexual contact with an infected

    Full Text Available CONTEXT: Abnormal serum ferritin levels are found in approximately 20%-30% of the patients with chronic hepatitis C and are associated with a lower response rate to interferon therapy. OBJECTIVE: To determine if the presence of HFE gene mutations had any effect on the sustained virological response rate to interferon based therapy in chronic hepatitis C patients with elevated serum ferritin. METHODS: A total of 44 treatment naÏve patients with histologically demonstrated chronic hepatitis C, all infected with hepatitis C virus genotype non-1 (38 genotype 3; 6 genotype 2 and serum ferritin above 500 ng/mL were treated with interferon (3 MU, 3 times a week and ribavirin (1.000 mg, daily for 24 weeks. RESULTS: Sustained virological response was defined as negative qualitative HCV-RNA more than 24 weeks after the end of treatment. Serum HCV-RNA was measured by qualitative in house polymerase chain reaction with a limit of detection of 200 IU/mL. HFE gene mutation was detected using restriction-enzyme digestion with RsaI (C282Y mutation analysis and BclI (H63D mutation analysis in 16 (37% patients, all heterozygous (11 H63D, 2 C282Y and 3 both. Sustained virological response was achieved in 0 of 16 patients with HFE gene mutations and 11 (41% of 27 patients without HFE gene mutations (P = 0.002; exact Fisher test. CONCLUSION: Heterozigozity for H63D and/or C282Y HFE gene mutation predicts absence of sustained virological response to combination treatment with interferon and ribavirin in patients with chronic hepatitis C, non-1 genotype and serum ferritin levels above 500 ng/mL.

    Full Text Available Treatment rates with interferon-based therapies for chronic hepatitis C have been low. Our aim was to perform a systematic review of available data to estimate the rates and barriers for antiviral therapy for chronic hepatitis C.We conducted a systematic review and meta-analysis searching MEDLINE, SCOPUS through March 2016 and abstracts from recent major liver meetings for primary literature with available hepatitis C treatment rates. Random-effects models were used to estimate effect sizes and meta-regression to test for potential sources of heterogeneity.We included 39 studies with 476,443 chronic hepatitis C patients. The overall treatment rate was 25.5% (CI: 21.1-30.5% and by region 34% for Europe, 28.3% for Asia/Pacific, and 18.7% for North America (p = 0.008. On multivariable meta-regression, practice setting (tertiary vs. population-based, p = 0.04, region (Europe vs. North America p = 0.004, and data source (clinical chart review vs. administrative database, p = 0.025 remained significant predictors of heterogeneity. The overall treatment eligibility rate was 52.5%, and 60% of these received therapy. Of the patients who refused treatment, 16.2% cited side effects, 13.8% cited cost as reasons for treatment refusal, and 30% lacked access to specialist care.Only one-quarter of chronic hepatitis C patients received antiviral therapy in the pre-direct acting antiviral era. Treatment rates should improve in the new interferon-free era but, cost, co-morbidities, and lack of specialist care will likely remain and need to be addressed. Linkage to care should even be of higher priority now that well-tolerated cure is available.

    Hepatitis C virus (HCV) chronically infects 170 million people worldwide. Until recently, combination therapy with peginterferon-α (pegIFN) and ribavirin (RBV) has been the standard of care. However, for many patients, especially those infected with the most common HCV genotype 1 (HCV-1), this treatment has resulted in unsatisfactory treatment response rates. Many clinical factors, including pharmacogenetics, influence the treatment response rate. Genetic variation in the interleukin 28B (IL28B) gene is the major determinant of treatment response, a finding that has been replicated in multiple independent cohorts. This review focuses on the association between pharmacogenetics and conventional pegIFN/RBV therapy in patients infected with HCV non-genotype 1; patients reinfected with HCV after liver transplantation; and patients coinfected with HCV and human immunodeficiency virus. We also review the pharmacogenetic data for boceprevir and telaprevir triple therapy in patients with HCV-1 infection, as well as viral genomic polymorphisms and genetic variants that may protect against anemia. Pharmacogenetic information offers a personalized medicine approach to help clinicians and patients make better informed decisions to maximize response and minimize toxicity for the treatment of chronic HCV infection. © 2013 Pharmacotherapy Publications, Inc.

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

    Altered T cell homeostasis in chronic hepatitis C virus (HCV) infection has been demonstrated. However, it is unknown if fibrosis is associated with more perturbed T cell homeostasis in chronic HCV infection. The aim of the present study was to examine and compare T cell subsets including recent...... thymic emigrants (RTE), naive, memory, senescent, apoptotic and IL-7 receptor α (CD127) expressing CD4+ and CD8+ T cells as well as telomere length and interferon-γ production in HCV-infected patients with (n=25) and without (n=26) fibrosis as well as in healthy controls (n=24). Decreased proportions...... of CD4+ and CD8+ RTE were found in HCV-infected patients, especially in HCV-infected patients with fibrosis (14.3% (9.7-23.0) and 28.8% (16.1-40.5), respectively) compared to healthy controls (24.2% (16.3-32.1), P=0.004, and 39.1% (31.6-55.0), P=0.010, respectively). Furthermore, HCV-infected patients...

    Serum hyaluronic acid (HA) is a well-established marker of fibrosis in patients with chronic liver disease (CLD). However, the relationship between serum HA level and protein-energy malnutrition (PEM) in patients with CLD is an unknown. We aimed to examine the relationship between serum HA level and PEM in patients with chronic hepatitis C (CHC) compared with the relationships of other serum markers of fibrosis. A total of 298 CHC subjects were analyzed. We defined patients with serum albumin level of ≤3.5 g/dL and nonprotein respiratory quotient <0.85 using indirect calorimetry as having PEM. We investigated the effect of serum HA level on the presence of PEM. Receiver operating characteristic curve (ROC) analysis was performed for calculating the area under the ROC (AUROC) for serum HA level, platelet count, aspartate aminotransferase (AST) to platelet ratio index, FIB-4 index, AST to alanine aminotransferase ratio, and Forns index for the presence of PEM. The median serum HA level in this study was 148.0 ng/mL (range: 9.0-6340.0 ng/mL). In terms of the degree of liver function (chronic hepatitis, Child-Pugh A, B, and C), the analyzed patients were well stratified according to serum HA level (overall significance, P < 0.0001). The median value (range) of serum HA level in patients with PEM (n = 61) was 389.0 ng/mL (43.6-6340.0 ng/mL) and that in patients without PEM (n = 237) was 103.0 ng/mL (9.0-783.0 ng/mL) (P < 0.0001). Among 6 fibrosis markers, serum HA level yielded the highest AUROC with a level of 0.849 at an optimal cut-off value of 151.0 ng/mL (sensitivity 93.4%; specificity 62.0%; P < 0.0001). In the multivariate analysis, serum HA level was found to be a significant prognostic factor related to the presence of PEM (P = 0.0001).In conclusion, serum HA level can be a useful predictor of PEM in patients with CHC.

    2012-03-01

    Full Text Available Cryoglobulinaemic mononeuritis multiplex (MNM is an extrahepatic manifestation of chronic hepatitis C virus (HCV infection for which interferon-based antiviral therapy is currently the treatment of choice. Rarely MNM can be associated with HCV treatment though generally in the setting of pre-existing cryoglobulinaemia and detectable HCV viraemia. We report an unusual case of de novo MNM occurring late during the course of pegylated interferon and ribavirin therapy for chronic HCV infection, following a prolonged period of viral suppression. The patient had no evidence of cryoglobulinaemia prior to HCV treatment and undetectable HCV RNA levels at the time of presentation with MNM. The case raises the possibility that MNM could develop as an adverse immunomodulatory effect of pegylated interferon therapy.

    The severity of chronic hepatitis C (CHC) is modulated by host and environmental factors. Several reports suggest that caffeine intake exerts hepatoprotective effects in patients with chronic liver disease. The aim of this study was to evaluate the impact of caffeine consumption on activity grade and fibrosis stage in patients with CHC. A total of 238 treatment-naïve patients with histologically-proven CHC were included in the study. Demographic, epidemiological, environmental, virological, and metabolic data were collected, including daily consumption of alcohol, cannabis, tobacco, and caffeine during the six months preceding liver biopsy. Daily caffeine consumption was estimated as the sum of mean intakes of caffeinated coffee, tea, and caffeine-containing sodas. Histological activity grade and fibrosis stage were scored according to Metavir. Patients (154 men, 84 women, mean age: 45±11 years) were categorized according to caffeine consumption quartiles: group 1 (678 mg/day, n=60). There was a significant inverse relationship between activity grade and daily caffeine consumption: activity grade>A2 was present in 78%, 61%, 52%, and 48% of patients in group 1, 2, 3, and 4, respectively (pA2 (OR=0.32 (0.12-0.85). Caffeine intake showed no relation with fibrosis stage. Caffeine consumption greater than 408 mg/day (3 cups or more) is associated with reduced histological activity in patients with CHC. These findings support potential hepatoprotective properties of caffeine in chronic liver diseases. Copyright © 2010 European Association for the Study of the Liver. Published by Elsevier B.V.

    During the last decade hepatitis E infections have been recognized as a health problem in high-income countries, where hepatitis E virus genotype 3 is endemic. The infection is often self-limiting, but may develop into chronic infection in immunocompromised patients, especially in solid organ recipients. If these patients or patients with underlying liver disease get hepatitis E infection, they may develop liver failure and cirrhosis. Hepatitis E virus is occasionally found in blood products and transfusion transmission has been reported. We present the first case of chronic hepatitis E infection in a heart transplant recipient in Sweden. A 63-year-old Swedish white man presented with highly elevated liver enzymes 6 months after heart transplantation. Polymerase chain reaction revealed chronic hepatitis E infection, caused by a virus strain found infecting symptomatic cases in Sweden and other European countries. During transplantation, he received blood products from 17 donors, and transfusion transmission is highly likely. The only detectable marker for hepatitis E infection was hepatitis E virus ribonucleic acid for more than 2 months before anti-hepatitis E virus developed. He was treated successfully with ribavirin and decreased immunosuppression. Our patient was probably infected through contaminated blood products and subsequently developed chronic infection, which was cured upon treatment. This highlights the need for evaluating the problem with chronic hepatitis E infection in immunocompromised patients, and for discussion concerning screening of blood products. Polymerase chain reaction-based methods are recommended for diagnosing hepatitis E infection in patients with compromised immunity. In addition, knowledge needs to be gained on the infecting virus strain, which may be more virulent than other strains.

    Full Text Available In Brazil, the treatment of hepatitis C virus (HCV infection is funded by the national public health system (SUS. To evaluate treatment results in the state of Mato Grosso, central Brazil, we have consulted the files of the office of the State Department of Health responsible for supplying such medications. We obtained information on 232 treatments of 201 patients who underwent treatment in or prior to 2008. The study was conducted by reviewing medical records, making telephone calls and interviewing the assistant physicians. Thirty-nine patients (19.4% had cirrhosis and HCV genotype 1 predominated (64.3%. Excluding patients with comorbidities or treatment without ribavirin we analysed 175 treatments (sustained virologic response occurred in 32.6% of cases. Twenty-six of these 175 were retreatments and the sustained virological response (SVR rate among them was 30.8%; the SVR rate was 32.9% among those receiving treatment for the first time. The SVR rate of genotype 1 patients was 27.8%, whereas it was 37.5% in non-1 genotype patients. The adjusted multivariate analysis showed association of SVR with the absence of cirrhosis [odds ratio (OR: 7.7; confidence interval (CI 95%: 2.5, 33.3], the use of pegylated interferon (OR: 5.8; CI 95%: 1.5, 21.4, non-1 genotype (OR: 5.3; CI 95%: 1.7, 16.7 and uninterrupted treatment (OR: 9.0; CI 95%: 3.3, 45.4. The SVR rates were similar to those found in other Brazilian studies about HCV, but lower than those found in national and international clinical trials. These data suggest that the treatments of chronic hepatitis C that are made available by SUS does not, under normal conditions, work as well as the original controlled studies indicated.

    Little is known about how hepatitis C (HCV) infection affects cognitive function in children. The aim of the study was to assess the impact of HCV infection on cognitive function of children with normal liver functions and their relationships to endogenous IFN-α, IL-6 and TNF-α. IFN-α, IL-6 and TNF-α were measured and the Arabic version of the Stanford-Binet test used to assess cognitive functions in 35 children with HCV infection and 23 controls. Serum levels of IL-6 and IFN-α were significantly higher in patients compared to controls. There was a significant effect on vocabulary, comprehension, and abstract visual reasoning, quantitative reasoning and bead memory tests, as well as total short-term memory and intelligence quotient in patients compared to controls. There was a significant positive correlation between IFN-α and IL-6. Also there were significant negative correlations between IFN-α and Abstract visual reasoning test, Quantitative reasoning test, Bead memory test, Total short-term memory and Intelligence quotient; and between IL-6 and Abstract visual reasoning test, Quantitative reasoning test and Intelligence quotient. There was no significant correlation between TNF-α and any of the cognitive functions. Cytokine levels were not related to demographic characteristics of the patients or viral load (PCR). Children with chronic hepatitis C infection in its early stages showed signs of cognitive impairment, with the memory tasks being mostly affected. There was a significant correlation between endogenous cytokines and cognitive impairment in these children. Further studies are needed to define the effect of successful antiviral treatment. © 2014 John Wiley & Sons Ltd.

    Full Text Available Jurriën GP Reijnders, Harry LA JanssenDepartment of Gastroenterology and Hepatology, Erasmus University Medical Center Rotterdam, The NetherlandsAbstract: In the field of HIV management, tenofovir disoproxil fumarate (TDF plays a pivotal role and has been demonstrated to be a safe and well-tolerated antiviral agent. Recent data showed the efficacy of TDF in the treatment of chronically hepatitis B virus (HBV-infected patients. TDF was superior to adefovir dipivoxil (ADV in both nucleos(tide-naïve HBeAg-positive and HBeAg-negative HBV patients, and appeared to be one of the most potent antiviral agents so far. In addition, several reports showed that TDF was also effective in the nucleos(tide-experienced population, although conflicting results have been presented concerning patients with genotypic resistance to ADV. TDF seems to have a good resistance profile as well. The rtA194T mutation in association with lamivudine resistance may confer resistance to TDF, although both in vivo and in vitro studies regarding this mutation demonstrate conflicting results. As treatment with TDF may be associated with nephrotoxicity, all TDF-treated patients should be monitored for renal function at baseline and periodically thereafter. While the relative roles of interferon vs nucleos(tide analogues (NA as initial anti-HBV therapy remains unclear, TDF will probably become one of the key factors in HBV management both as first-choice NA for nucleos(tide-naïve patients and as rescue therapy for nucleos(tide-experienced patients.Keywords: hepatitis B, antiviral therapy, tenofovir, HBV

    Limited data exist with regard to treatment outcomes in Asian Americans with chronic hepatitis C (CHC). We evaluated sofosbuvir (SOF)-based regimens in a national cohort of Asian Americans. Eligible Asian Americans patients with CHC who had posttreatment follow-up of 24 weeks for SOF -based therapies from December 2013 to June 2017 were enrolled from 11 sites across the United States. The primary endpoint was sustained virologic response (SVR) rates at posttreatment weeks 12 and 24. Secondary endpoints were to evaluate safety by tolerability and adverse events (AEs). Among 231 patients screened, 186 were enrolled. At baseline, 31% (57/186) patients were cirrhotic, 34% (63/186) were treatment experienced. Most of the subjects (42%, 79/186) received ledispavir/SOF therapy. The overall SVR12 was 95%, ranging from 86% in genotype (GT) 1b on SOF+ribavirin to 100% in GT 1b patients on ledipasvir/SOF at subgroup analyses. SVR12 was significantly lower in cirrhotic than in noncirrhotic patients [88% (50/57) vs. 98% (126/129), P<0.01]. Stratified by GT, SVR12 were: 96% (43/45) in GT 1a; 93% (67/72) in GT 1b; 100% (23/23) in GT 2; 90% (19/21) in GT 3; 100% (1/1) in GT 4; 83% (5/6) in GT 5; and 100% (16/16) in GT 6. Cirrhotic patients with treatment failure were primarily GT 1, (GT 1a, n=2; GT 1b, n=4) with 1 GT 5 (n=1). Patients tolerated the treatment without serious AEs. Late relapse occurred in 1 patient after achieving SVR12. In Asian Americans with CHC, SOF-based regimens were well tolerated without serious AEs and could achieve high SVR12 regardless of hepatitis C viral infection GT.

    Verapamil (VRP), a cardiovascular pharmaceutical widely distributed and persistent in the aquatic environment, has potential toxicity to fish and other aquatic organisms. However, the molecular mechanisms that lead to these toxic effects are not well known. In the present study, proteomic analysis has been performed to investigate the protein patterns that are differentially expressed in liver of rainbow trout exposed to sublethal concentrations of VRP (0.5, 27.0, and 270 μg/liter) for 42 days. Two-dimensional electrophoresis coupled with MALDI-TOF/TOF mass spectrometry was employed to detect and identify the protein profiles. The analysis revealed that the expression of six hepatic
