    Introduction
    Although hepatitis is frequently observed during antituberculosis (anti-TB) therapy, acute viral hepatitis should be ruled out first, especially in the endemic areas. In addition to common types of viral hepatitis, ie, hepatitis A, hepatitis B, and hepatitis C viruses, Epstein-Barr virus (EBV) may result in hepatitis in some cases..
    Case Presentation
    Herein, we reported a critically ill patient who developed cholestatic hepatitis in the intensive care unit during the anti-TB therapy, which was misdiagnosed as anti-TB agents-induced hepatitis in the beginning. Further serologic tests and liver biopsy confirmed the diagnosis of EBV hepatitis. In contrast to previously reported hepatitis by EBV, which had presented with transient liver dysfunction and self-limiting illness, hepatitis with progressive jaundice was followed by coagulopathy and encephalopathy in our case and the patient died of hepatic failure complications..
    Conclusions
    According to the presented case and subsequent literature review on fatal EBV hepatitis, clinicians should consider EBV infection in the differential diagnosis when hepatitis occurs in critically ill patients during the anti-TB therapy. Although hepatitis caused by EBV is mostly self-limited, some might be fetal..

    Hiva Saffar, Mohammed Jafar Saffar, Abolghasem Ajami, Ali Reza Khalilian, Kian Shams-Esfandabad, Araz Mohammad Mirabi * Page 4
    Background
    The long-term duration of cell-mediated immunity induced by neonatal hepatitis B virus (HBV) vaccination is unknown..
    Objectives
    Study was designed to determine the cellular immunity memory status among young adults twenty years after infantile HB immunization..Patients and
    Methods
    Study subjects were party selected from a recent seroepidemiologic study in young adults, who had been vaccinated against HBV twenty years earlier. Just before and ten to 14 days after one dose of HBV vaccine booster injection, blood samples were obtained and sera concentration of cytokines (interleukin 2 and interferon) was measured. More than twofold increase after boosting was considered positive immune response. With regard to the serum level of antibody against HBV surface antigen (HBsAb) before boosting, the subjects were divided into four groups as follow: GI, HBsAb titer < 2; GII, titer 2 to 9.9; GIII, titer 10 to 99; and GIV, titers ≥ 100 IU/L. Mean concentration level (MCL) of each cytokines for each group at preboosting and postboosting and the proportion of responders in each groups were determined. Paired descriptive statistical analysis method (t test) was used to compare the MCL of each cytokines in each and between groups and the frequency of responders in each group..
    Results
    Before boosting, among 176 boosted individuals, 75 (42.6%) had HBsAb 10 IU/L and were considered seroprotected. Among 101 serosusceptible persons, more than 80% of boosted individuals showed more than twofold increase in cytokines concentration, which meant positive HBsAg-specific cell-mediated immunity. MCL of both cytokines after boosting in GIV were decreased more than twofold, possibly because of recent natural boosting..
    Conclusions
    Findings showed that neonatal HBV immunization was efficacious in inducing long-term immunity and cell-mediated immune memory for up to two decades, and booster vaccination are not required. Further monitoring of vaccinated subjects for HBV infections are recommended..

  • Estrogen Receptor Alpha Expression and Liver Fibrosis in Chronic Hepatitis C Virus Genotype 1b: A Clinicopathological Study
    Mustafa Cengiz *, Seren Ozenirler, Guldal Yilmaz Page 5
    Background
    Hepatic damage due to chronic hepatitis C virus (HCV) genotype 1b infection varies widely..
    Objectives
    We aimed to investigate whether estrogen receptor alpha (ERα) plays a role in liver fibrosis in patients infected with HCV genotype 1b..Patients and
    Methods
    All the consecutive patients who received the same standard treatment protocol for HCV genotype 1b were subdivided into two subgroups according to their fibrosis scores as fibrotic stages < 2 in mild fibrosis group and fibrotic stages ≥ 2 in advanced fibrosis group, depending on the presence of septal fibrosis. ERα was stained in liver biopsy specimens. Demographics and clinical properties were compared between the groups. Multivariate logistic regression analysis was performed to predict advanced fibrosis..
    Results
    There were 66 patients in the mild fibrosis group and 24 in the advanced fibrosis group. Among the mild and advanced fibrosis groups, 65.1% and 50%were female, respectively (P = 0.19). There was an inverse correlation between ERα and fibrotic stage (r: -0.413; P < 0.001). Age, platelet counts, neutrophil counts, Alanine aminotransferase (ALT), Aspartate aminotransferase (AST), Gamma glutamyl transferase (GGT) and ERα were statistically significant in the univariate analysis. In multivariate logistic regression analyses, ERα expression continued to be an independent predicting factor of liver fibrosis in patients infected with chronic HCV genotype 1b (OR: 0.10; 95% CI: 0.018-0.586; P < 0.001)..
    Conclusions
    ERα expression in liver was inversely correlated with liver fibrosis among patients infected with chronic HCV genotype 1b..

    Background
    The prognosis of hepatocellular carcinoma (HCC) is unfavorable and needs serum markers that could detect it early to start therapy at a potentially curable phase..
    Objectives
    The aim of this study was to determine the value of serum soluble tumor necrosis factor (TNF) receptor-IIα (sTNFR-IIα) in diagnosis of HCC in patients with chronic hepatitis C virus (HCV) infection..Patients and
    Methods
    The study was performed on 110 subjects who were classified into five groups. Group I included 20 patients with chronic noncirrhotic HCV infection and persistently normal transaminases for ≥6 months. Group II included 20 patients with chronic noncirrhotic HCV infection and elevated transaminases. Group III included 20 patients with Chronic HCV infection and liver cirrhosis. Group IV included 20 patients with chronic HCV infection with liver cirrhosis and HCC. Group V included 30 healthy age and sex-matched controls. Medical history was taken from all participants and they underwent clinical examination and abdominal ultrasonography. in addition, the following laboratory tests were requested: liver function tests, complete blood count, HBsAg, anti-HCVAb, HCV-RNA by qualitative PCR, and serum levels of α-fetoprotein (AFP) and sTNFR-IIα..
    Results
    The serum level of sTNFR-IIα was significantly higher in patients with HCC in comparison to the other groups. A positive correlation was found between the serum levels of sTNFR-IIα and AST and ALT in patients of group-II. Diagnosis of HCC among patients with HCV infection and cirrhosis could be ascertained when sTNFR-IIα is assessed at a cutoff value of ≥ 250 pg/mL..
    Conclusions
    Serum sTNFR-IIα could be used as a potential serum marker in diagnosing HCC among patients with HCV infection..

    Introduction
    Hepatitis E is an emerging disease in developed countries with an increasing incidence. In developed countries, HEV genotype 3 prevails as a zoonotic disease carried by wild boars or pigs, which usually causes asymptomatic infection..
    Case Presentation
    An asymptomatic HBsAg carrier was tested regularly at a German university hospital and showed no signs of chronic hepatitis B (CHB) activity. At a routine visit, elevated aminotransferases were detected while HBV DNA remained low and the patient was clinically asymptomatic. The laboratory signs of acute hepatitis resolved spontaneously. When aminotransferases returned to normal limits, the patient showed a flare of HBV-replication, which resolved spontaneously. In follow-up, further investigations revealed a resolved hepatitis E (HEV) superinfection causing an acute hepatitis before the HBV flare. No potential risk factors for HEV infection were identified..
    Conclusions
    Elevated aminotransferases in CHB patients are most commonly caused by exacerbation of CHB. Nevertheless, when HBV DNA is not elevated, other reasons should be excluded. Amongst others, superinfection with another hepatotropic virus can be the reason for decompensation of chronic hepatitis B. This case report describes an asymptomatic HEV superinfection followed by a flare in HBV replication in an HBsAg carrier without signs of HBV replication for eight years. In CHB carriers with signs of acute hepatitis, rare causes should be considered as well. HEV should be a part of routine laboratory evaluation for hepatitis flares given the rising number of infections..

    Background
    Hepatitis C Virus (HCV), a public health problem, is an enveloped, single-stranded RNA virus and a member of the Hepacivirus genus of the Flaviviridae family. Liver cancer, cirrhosis, and end-stage liver are the outcomes of chronic infection with HCV. HCV isolates show significant heterogeneity in genetics around the world. Therefore, determining HCV genotypes is a vital step in determining prognosis and planning therapeutic strategies..
    Objectives
    As distribution of HCV genotypes is different in various geographical regions and HCV genotyping of patients has not been investigated in Zanjan City, this study was designed for the first time, to determine HCV genotypes in the region and to promote the impact of the treatment..
    Materials And Methods
    Serum samples of 136 patients were collected and analyzed for anti-HCV antibodies using ELISA (The enzyme-linked immunosorbent assay) method. Then, positive samples were exposed to RT-PCR, which was performed under standard condition. Afterwards, they investigated for genotyping using allele-specific PCR (AS-PCR), and HCV genotype 2.0 line probe assay (LiPA)..
    Results
    Samples indicated 216 bp bands on 2% agarose gel. Analyses of the results demonstrated that the most dominant subtype was 3a with frequency of 38.26% in Zanjan Province followed by subtypes of 1b, 1a, 2, and 4 with frequencies of 25.73%, 22.05%, 5.14%, and 4.41%, respectively. The frequency of unknown HCV genotypes was 4.41%..
    Conclusions
    According to the results, it was found that HCV high prevalent genotype in Zanjan is subtype 3a. Analysis of the results provides identification of certain HCV genotypes, and these valuable findings could affect the type and duration of the treatment..

    Background
    The immune system plays important roles in determining the outcomes of hepatitis C virus (HCV) infection. Interleukin-23 and -27 (IL-23 and IL-27) are two novel IL-12 cytokine family members known to enhance the T-lymphocyte response, but their precise involvement in HCV infection is not well known..
    Objectives
    We investigated the serum IL-27 and IL-23 levels in patients with HCV infection and in healthy individuals..Patients and
    Methods
    In this case-control study, we assessed IL-23 and IL-27 levels in serum of 37 healthy individuals and 64 patients with chronic HCV using Enzyme-linked immunosorbent assay (ELISA). The relationship of cytokines level with liver enzymes (ALT, AST, and ALP), HCV genotype and viral load were analyzed. The differences of these cytokine levels in the groups of treatment and no treatment was compared. HCV genotypes were classified by HCV-specific primers methods. HCV RNA loads were determined by fluorescence quantitative PCR..
    Results
    Serum level of IL-23 was higher in HCV infected patients compared to control group (P = 0.005). However, no significant difference was seen in IL-27 serum level between patients compared to the control group (P = 0.65). There was no significant difference in IL-23 and IL-27 level between genotype 1 HCV-infected- and 3a HCV-infected- patients. Positive moderate correlation between IL-23 and IL-27 with viral load was found in type 3a and 1 HCV-infected patient. Positive relative correlation was seen between ALT and IL-23 in 1a HCV-infected patients, which was higher than 3a HCV-infected patients; but there were no significant difference between serums liver enzymes with IL-23 and IL-27 in respect to genotype 3a and 1a HCV-infected patients.
    Conclusions
    These findings may reflect a vigorous pro-inflammatory reaction orchestrated by the host immune system against chronic HCV. Also, a better understanding of the involvement mechanism considering the correlation between other genotypes with inflammatory cytokines in various stages of disease can be obtained..
