Challenges and opportunities in the management of chronic hepatitis B infection

Tue, 29 Mar 2016 09:23:41 +0100

Abstract: HBsAg seroclearance before the age of 50 years of age is associated with decreased incidence of hepatocellular carcinoma. Studies of spontaneous HBsAg seroclearance select special population with low viral activities. However HBsAg seroclearance is only achievable in 8-11% of patients with the current treatment agents (interferon and nucleoside analogues [NAs]). The pattern of HBsAg level decline during NA treatment is variable. (Source: International Journal of Infectious Diseases)

The long-term impact of antiretroviral therapy in resource-limited settings

Tue, 29 Mar 2016 09:23:40 +0100

Abstract: With the advent of antiretroviral therapy (ART), HIV has shifted to a chronic manageable condition, even in resource-limited settings. Now, the long-term effects of being on ART and living with HIV are emerging. These include the adverse effects of long-term ART and morbidity due to non AIDS complications such as cardiovascular, hepatic, renal, metabolic and neurocognitive disease, cancers and ageing as well as complications due to hepatitis B and C co-infection. Although first and second-line antiretrovirals are available in resource-limited settings, new antiretrovirals are urgently needed in order to sustain HIV as a chronic manageable condition.

Prevalence of hepatitis delta virus in Sindh and Punjab (Pakistan) epidemiological survey.

Tue, 29 Mar 2016 09:23:38 +0100

Background: Hepatitis D virus or delta virus (HDV) is a small, defective RNA virus that can infect only individuals who have hepatitis B virus which acts as the carrier host. The prevalence of HDV antibodies in Pakistani hepatitis B surface antigen (HBsAg) positive individuals is approximately 16.6%. So there is a pool of at least 800,000 anti-HDV positive HBsAg positive individuals in the country. Although the prevalence of hepatitis virus infections in Pakistan is still unknown, limited data indicate that the exposure rate to HBV is 35-38% with 4% being carriers and 32% having anti-HBV surface antibodies through natural conversion.

Mother T follicular helper cells prevent vertical transmission of Hepatitis B to their babies

Tue, 29 Mar 2016 09:23:38 +0100

Background: Chronic Hepatitis B infection (CHBV) is a leading cause of advanced liver diseases. Mother to child transmission accounts for most cases of CHBV infections. The risk is highest in HBsAg+ve and HBeAg+ve mothers (transmission rate: 70%–90%). Follicular T helper cells (TFH) have shown a preventive role against HBV through activating the B cell mediated humoral immunity in patients. Role of TFh cells in HBV Transmission is elusive. Hypothesis: TFH cells are essential for preventing HBV transmission and impairment of these cells may leads to vertical HBV transmission. (Source: International Journal of Infectious Diseases)

Identification of occult hepatitis B virus (HBV) infection and viral antigens in healthcare workers who presented low to moderate levels of anti-HBs after HBV vaccination

Tue, 29 Mar 2016 09:23:35 +0100

Background: Worldwide, healthcare workers (HCW)s show different levels of response to hepatitis B virus (HBV) vaccine. One of the factors associated with vaccine unresponsiveness may be the existence of current or past HBV infection. Regardless of the presence of HBsAg (overt infection), occult HBV infection (OBI, defined as presence of HBV DNA in the absence of HBsAg), might be also accounted in some non-or hypo-response cases.

HBcrAg is a predictor of hepatocellular carcinoma development: an analysis using time-dependent receiver operating characteristics

Sun, 27 Mar 2016 22:00:00 +0100

Chronic hepatitis B (CHB) affects over 350 million people worldwide. Long-term complications of infection include cirrhosis and hepatocellular carcinoma (HCC), which together cause over 500,000 deaths annually [1,2]. Hepatitis B surface antigen (HBsAg)-positive patients have a 70-fold increased risk of developing HCC compared to their HBsAg-negative counterparts [3,4]. Hepatitis B virus (HBV) infection is endemic in Southeast Asia, China, Taiwan, Korea, and sub-Saharan Africa, where up to 85–95% of patients with HCC are HBsAg positive [5].

Combination Therapy With Tenofovir and Peginterferon May Not Be Translated Into Current Clinical Practice

Fri, 25 Mar 2016 23:00:00 +0100

We read with great interest the paper by Marcellin et al published in Gastroenterology.1 The authors demonstrated that combination therapy with tenofovir disoproxil fumarate (TDF) and pegylated interferon alfa-2a (Peg-IFN) for 48 weeks could result in higher rate of hepatitis B surface antigen (HBsAg) loss than either monotherapy in the multicenter international trial. However, the key question is whether the new strategy is good enough to be translated into current clinical practice. (Source: Gastroenterology)

C-terminal truncated hepatitis B virus X protein promotes hepatocellular carcinogenesis through induction of cancer and stem cell-like properties.

Fri, 25 Mar 2016 17:33:04 +0100

Authors: Ng KY, Chai S, Tong M, Guan XY, Lin CH, Ching YP, Xie D, Cheng AS, Ma S Abstract Tumor relapse after chemotherapy typifies hepatocellular carcinoma (HCC) and is believed to be attributable to residual cancer stem cells (CSCs) that survive initial treatment. Chronic infection with hepatitis B virus (HBV) has long been linked to the development of HCC. Upon infection, random HBV genome integration can lead to truncation of hepatitis B virus X (HBx) protein at the C-terminus. The resulting C-terminal-truncated HBx (HBx-ΔC) was previously shown to confer enhanced invasiveness and diminished apoptotic response in HCC cells. Here, we found HBx-ΔC to promote the appearance of a CD133 liver CSC subset and confer cancer and stem cell-like features in HCC. HBx-ΔC was exclusively ...

Autoimmune hepatitis: a manifestation of immune reconstitution inflammatory syndrome in HIV infected patients?

Fri, 25 Mar 2016 06:03:02 +0100

Conclusions Immune reconstitution related autoimmune hepatitis should be considered in the differential diagnosis of hepatitis in the HIV-infected patient on antiretroviral therapy. Liver biopsy should be performed and the diagnosis confirmed using scoring systems developed by the Autoimmune Hepatitis Group. Timely treatment with prednisone and other agents for autoimmune hepatitis is indicated, and can be lifesaving in acute liver failure.

Conclusions: Treatment outcomes for HCV-6 patients are superior to those for HCV-1 patients and comparable to those of HCV-2 and HCV-3 patients, especially at 48 weeks. The level of fibrosis affects treatment outcome, but SVR rates are not significantly different between genders. IL28B and IFNL4 polymorphisms are not significantly associated with HCV-6 treatment outcome.Intervirology 2015;58:373-381 (Source: Intervirology)

Management of hepatitis B reactivation in immunosuppressed patients: An update on current recommendations.

Fri, 25 Mar 2016 00:29:02 +0100

Authors: Bessone F, Dirchwolf M Abstract The proportion of hepatitis B virus (HBV) previously exposed patients who receive immunosuppressive treatment is usually very small. However, if these individuals are exposed to potent immunosuppressive compounds, the risk of HBV reactivation (HBVr) increases with the presence of hepatitis B surface antigen (HBsAg) in the serum. Chronic HBsAg carriers have a higher risk than those who have a total IgG anticore as the only marker of resolved/occult HBV disease. The loss of immune control in these patients may results in the reactivation of HBV replication within hepatocytes. Upon reconstitution of the immune system, infected hepatocytes are once again targeted and damaged by immune surveillance in an effort to clear the virus. There are diffe...

Posttreatment Hepatitis B Surface Antigen Seroreversion: The Bane of Combination Therapy in Chronic Hepatitis B?

Thu, 24 Mar 2016 23:00:00 +0100

In this issue of Gastroenterology, Marcellin et al present the results of a landmark global randomized trial (Study 0149) comparing different regimes of pegylated interferon alfa-2a (PEG-IFN), tenofovir, or the combination for chronic hepatitis B.1 The primary endpoint of the study was defined as hepatitis B surface antigen (HBsAg) clearance, which is considered the closest outcome to cure in chronic hepatitis B. From their study, the authors conclude that 48 weeks of PEG-IFN plus tenofovir increases HBsAg loss compared with PEG-IFN alone. (Source: Gastroenterology)

Oral administration of synthetic selenium nanoparticles induced robust Th1 cytokine pattern after HBs antigen vaccination in mouse model

Tue, 22 Mar 2016 23:00:00 +0100

Hepatitis B virus (HBV) infection is known as a life-threatening liver infection and leads to chronic liver disease if left untreated. Nevertheless, the prevalence of HBV infection has been reduced by an approved vaccination approach using recombinant Hepatitis B surface Antigen (HBsAg) and Alum, known as the HBV vaccine. Alum can be used as an adjuvant to increase HBsAg immunogenicity as a strong Th2 stimulator. There is a vital need to stimulate Th1 immunity by HBsAg vaccination; however, the present vaccine does not induce a prophylactic immune response in some groups.

Fibronectin EDA and CpG synergize to enhance antigen-specific Th1 and cytotoxic responses.

Tue, 22 Mar 2016 23:00:00 +0100

Authors: Julier Z, de Titta A, Grimm AJ, Simeoni E, Swartz MA, Hubbell JA Abstract Subunit vaccines, employing purified protein antigens rather than intact pathogens, require the addition of adjuvants for enhanced immunogenicity with a correct balance between strong activation of the immune system and low toxicity. Here we show that the endogenous (i.e., autologous) non-toxic TLR4 agonist extra domain A type III repeat of fibronectin (FNIII EDA) can synergize with the exogenous (i.e., bacterial), toxic-at-high-dose, TLR9 agonist CpG to induce efficient cellular immune responses while keeping the dose of CpG low. The efficacy of the combined TLR agonists, even at half-doses, led to stronger dendritic cell activation, enhanced cytotoxic T lymphocyte activation as well as stronger hum...

The Viral Hepatitis Prevention Board met in London, UK (June 5–6, 2015), to discuss options towards a future free of viral hepatitis. Hepatitis B vaccine was introduced in 1982 and is now included in childhood immunisation programmes in 194 countries,1 with substantial declines in incidence rates; hepatitis B virus-dependent hepatitis D prevalence rates have also plummeted. A hepatitis A vaccine is widely used, and a hepatitis E vaccine has become commercially available in China. Chronic hepatitis B treatment exists, and hepatitis C treatment has single-dose oral medicines that can cure up to 95% of cases with shortened treatment and fewer side-effects.

Id: 29: invasive liver abscess syndrome in north america

Mon, 21 Mar 2016 23:00:00 +0100

Discussion Klebsiella pneumoniae, a member of the Enterobacteriaceae family, is a pathogen with worldwide distribution. Most community-acquired Klebsilla pneumoniae infections cause pneumonia or urinary tract infections. Invasive liver abscess syndrome is very rare in western countries. For the past 2 decades, a distinct clinical syndrome has been emerging in Southeast Asia that is characterized by bacteremia, liver abscesses, and metastatic infections. In the past decade, few patients were diagnosed as having a liver abscess caused by K pneumoniae in two case series in the USA. Most community-acquired Klebsilla pneumoniae infections cause pneumonia or urinary tract infections. Invasive liver abscess syndrome is very rare in western countries. Clinicians should be aware about invasive kleb...

Id: 30: hepatitis b virus reactivation in an inactive carrier of chronic hbv after the initiation of treatment for tiberculosis

Mon, 21 Mar 2016 23:00:00 +0100

Discussion HBV reactivation is diagnosed by an increase HBV DNA in chronic carrier with undetectable viral load or rise HBV DNA ≥10-fold increase in HBV DNA compared with baseline. Reactivation of HBV after starting chemotherapy or immunosuppressive medications is well described. Our case report is the first to describe HBV reactivation after starting Ethambutol, levofloxacin and Capreomycin against multidrug resistant mycobacterium tuberculosis. Most studies reported that RIPE (Rifampin, Isoniazid, Pyrazinamide, and Ethambutol) tuberculosis therapy has shown no risk of HBV reactivation. One of the Multidrug resistant tuberculosis therapy agents which is levofloxacin can cause hepatoxicity but all previous studies did not report HBV reactivation. Capreomycin can cause severe hepato...

Isolated HBsAg positivity in a Mexican patient with newly diagnosed lupus nephritis

Mon, 21 Mar 2016 23:00:00 +0100

Conclusions Isolated HBsAg positivity may result from multiple causes, one of which is cross-reactivity. To the best of our knowledge, this is the first report of a false-positive reading using CMIA technique in an active lupus patient. It is reasonable to stress that lupus patients with a positive screening for HBV should undergo a confirmatory assay (such as genomic detection), since this diagnosis may have important therapeutic implications.

Association of HBV DNA replication with antiviral treatment outcomes in the patients with early-stage HBV-related hepatocellular carcinoma undergoing curative resection.

Mon, 21 Mar 2016 09:08:02 +0100

CONCLUSIONS: High baseline HBV DNA levels are associated with poor prognosis in the patients with early-stage HCC, and the antiviral treatment could generate survival benefits for the patients. Therefore, antiviral treatment should be given for these patients. However, the effect of antiviral treatment on the patients with low viral load remains unclear, and further investigation is warranted.

Functional Immune Anatomy of the Liver—As an Allograft

Mon, 21 Mar 2016 00:00:00 +0100

The liver is an immunoregulatory organ in which a tolerogenic microenvironment mitigates the relative “strength” of local immune responses. Paradoxically, necro‐inflammatory diseases create the need for most liver transplants. Treatment of hepatitis B virus, hepatitis C virus, and acute T cell–mediated rejection have redirected focus on long‐term allograft structural integrity. Understanding of insults should enable decades of morbidity‐free survival after liver replacement because of these tolerogenic properties. Studies of long‐term survivors show low‐grade chronic inflammatory, fibrotic, and microvascular lesions, likely related to some combination of environment insults (i.e. abnormal physiology), donor‐specific antibodies, and T cell–mediated immunity. The resulta...

miR-146a negatively regulates NK cell functions via STAT1 signaling.

Sun, 20 Mar 2016 23:00:00 +0100

In this study, microRNA (miR)-146a expression increased in NK cells from CHB and HCC patients compared with NK cells from healthy donors, and miR-146a levels were negatively correlated to NK cell functions. Overexpression of miR-146a reduced NK cell-mediated cytotoxicity and the production of interferon (IFN)-γ and tumor necrosis factor-α, which were reversed upon inhibition of miR-146a. In NK cells, miR-146a expression was induced by interleukin (IL)-10 and transforming growth factor-β, but reduced after treatment with interleukin-12, IFN-α and IFN-β. We further revealed that miR-146a regulated NK cell functions by targeting STAT1. Taken together, upregulated miR-146a expression, at least partially, attributes to NK cell dysfunction in CHB and HCC patients. Therefore, miR-146a may be...

Hepatitis B Vaccination Coverage and Prevalence of Hepatitis B Surface Antigen Among Children in French Polynesia, 2014.

Sun, 20 Mar 2016 23:00:00 +0100

Authors: Patel MK, Le Calvez E, Wannemuehler K, Ségalin JM Abstract French Polynesia is considered to have moderate endemicity for chronic hepatitis B virus infection, with an estimated 3% of the population having hepatitis B surface antigen (HBsAg). From 1990 to 1992, a 3-dose hepatitis B vaccination series was introduced into the routine infant immunization schedule in French Polynesia, including a birth dose (BD). In 2014, a nationally representative 2-stage cluster survey was undertaken to evaluate the impact of the vaccination program on HBsAg prevalence among school children (∼6 years of age) in Cours Préparatoire (CP). Documented vaccination data were reviewed for all eligible children; children with consent were tested for HBsAg with a rapid point-of-care test. In total...

Distribution of hepatitis B infection in Brazil: the epidemiological situation at the beginning of the 21 st century

Sat, 19 Mar 2016 22:34:13 +0100

Abstract Brazil was formerly considered a country with intermediate hepatitis B endemicity, with large heterogeneity between Brazilian regions and areas of high prevalence, especially in the Amazon basin. Systematic vaccination of children was initiated in 1998. Between 2004 and 2009, a large population-based study reported decreased prevalence in all regions of Brazil. This review analyzed the current hepatitis B epidemiological situation in Brazil through a systematic search of the scientific literature in MEDLINE, LILACS, and CAPES thesis database, as well as disease notifications to the Information System for Notifiable Diseases. The search strategy identified 87 articles and 13 theses, resulting in 100 total publications. The most recent results indicate reduced hepatitis B prevalence...

Hepatitis B virus PreS2-mutant large surface antigen activates store-operated calcium entry and promotes chromosome instability.

Sat, 19 Mar 2016 17:51:03 +0100

Authors: Yen TT, Yang A, Chiu WT, Li TN, Wang LH, Wu YH, Wang HC, Chen L, Wang WC, Huang W, Chang CW, Chang MD, Shen MR, Su IJ, Wang LH Abstract Hepatitis B virus (HBV) is a driver of hepatocellular carcinoma, and two viral products, X and large surface antigen (LHBS), are viral oncoproteins. During chronic viral infection, immune-escape mutants on the preS2 region of LHBS (preS2-LHBS) are gain-of-function mutations that are linked to preneoplastic ground glass hepatocytes (GGHs) and early disease onset of hepatocellular carcinoma. Here, we show that preS2-LHBS provoked calcium release from the endoplasmic reticulum (ER) and triggered stored-operated calcium entry (SOCE). The activation of SOCE increased ER and plasma membrane (PM) connections, which was linked by ER- resident stro...

HLA-A is a Predictor of Hepatitis B e Antigen Status in HIV-Positive African Adults

Sat, 19 Mar 2016 00:00:00 +0100

Outcomes of chronic infection with hepatitis B virus (HBV) are varied, with increased morbidity reported in the context of human immunodeficiency virus (HIV) coinfection. The factors driving different outcomes are not well understood, but there is increasing interest in an HLA class I effect. We therefore studied the influence of HLA class I on HBV in an African HIV-positive cohort. We demonstrated that virologic markers of HBV disease activity (hepatitis B e antigen status or HBV DNA level) are associated with HLA-A genotype. This finding supports the role of the CD8+ T-cell response in HBV control, and potentially informs future therapeutic T-cell vaccine strategies. (Source: The Journal of Infectious Diseases)

Gianotti-crosti syndrome as presenting sign of cytomegalovirus infection: a case report and a critical appraisal of its possible cytomegalovirus etiology.

Sat, 19 Mar 2016 00:00:00 +0100

Gianotti-Crosti syndrome (GCS) is a self-limiting, mostly childhood-appearing, cutaneous eruption with a characteristic symmetrical acral distribution. The original cases, described by Gianotti in 1955, were associated with hepatitis B virus (HBV) infection, but, afterwards, other viral and bacterial infections, as well as immunizations, have been related with its etiology. Cytomegalovirus (CMV) infection is one of them, but only a few cases have been observed and more frequently in children than in adults [1,2]. (Source: Journal of Clinical Virology)

HBsAg blocks TYPE I IFN induced up-regulation of A3G through inhibition of STAT3.

Thu, 17 Mar 2016 23:00:00 +0100

In this study, we investigated Apobec3G expression and regulatory pathways during HBV infection. We show that over-expression of A3G leads to inhibition of HBV replication. We also show that IFN induces a significant increase in A3G protein expression, which is associated with STAT3 activation. We further show that A3G expression in HBV patients is lower compared to non-infected controls, possibly by HBsAg which inhibits IFN induced A3G up-regulation in a dose dependent manner. This process is likely mediated through inhibition of STAT3-Ser727 phosphorylation. The results presented in this study indicate that STAT3 plays an important role in IFN-induced A3G production, and HBsAg may correlated with poor response to IFN treatment.

Injection Site Lichenoid Dermatitis Following Pneumococcal Vaccination: Report and Review of Cutaneous Conditions Occurring at Vaccination Sites

Wed, 16 Mar 2016 23:00:00 +0100

Conclusions Dermatoses at the injection sites of vaccines can be granulomatous, immunity-related conditions, infections, lichenoid, neutrophilic, or pseudolymphomatous. Basal cell carcinoma and squamous cell carcinoma are the most common vaccination site-associated malignancies; however, melanoma and sarcomas (dermatofibrosarcoma protuberans, fibrosarcoma, and malignant fibrous histiocytoma) are also smallpox vaccine-related site neoplasms. A cutaneous immunocompromised district that is created by vaccine-induced local immunologic changes is hypothesized to be the pathogenesis of vaccination site reactions.
