    Background
    A head-to-head comparison of the 72-week and 48-week anti-HCV therapies in slow responders with genotype 1 infection has been performed in several randomized clinical trials (RCTs).
    Objectives
    This review aimed at summarizing and pooling the results of these studies.
    Materials And Methods
    RCTs that had evaluated the 72-week vs. 48-week anti-HCV therapy (peginterferon and ribavirin) in slow responders with HCV genotype 1 infection were systematically identified. A meta-analysis was performed using the random effects model. Heterogeneity in results was assessed on the basis of the Q statistics، and publication bias was evaluated by using Harbord’s modified test. The end point was set as a sustained virological response (SVR).
    Results
    Data of 1206 subjects were retrieved from 7 studies. A total of 631 patients had received extended therapy. Slow virological responders who received the 72-week therapy had a significantly higher probability of achieving SVR than their counterparts who received the 48-week therapy [RR = 1. 44 (95% CI، 1. 20–1. 73)]. With regard to publication biases، the heterogeneity in funnel plots was not significant (P = 0. 19، I2 = 30%، PHarbord = 0. 1).
    Conclusion
    Our meta-analysis showed that the 72-week therapy with peginterferon and ribavirin is significantly superior to the standard 48-week therapy in slow responderswith HCV genotype 1 infection.

    Background
    Data on the epidemiology of hepatitis B and C in Bosnia and Herzegovina (B&H) are lacking.
    Objectives
    To assess the prevalence of hepatitis B surface antigen (HBsAg) and anti-hepatitis C virus (anti-HCV) in blood samples of first time blood donors in a well-defined region of B&H. Our secondary goal was to estimate the prevalence of HBsAg and anti- HCV in the general population of the same region.Patients and
    Methods
    We evaluated 8196 blood samples for the presence of HBsAg and/ or anti-HCV, adjusted for differences in gender, and used the ratio estimation method to determine the prevalence in the general population.
    Results
    We analyzed 1263 (15.4%) female and 6933 (84.6%) male blood donors (male-tofemale ratio: 5.49 to 1). The adjusted prevalence of HBsAg among blood donors was 0.787% (95% CI = 0.535-1.038), while the prevalence of anti-HCV was 0.267% (95% CI = 0.016-0.519). There was no difference in the prevalence of HBsAg or anti-HCV between men and women. We estimate that the prevalence of HBsAg and anti-HCV in the general population is 1.057% to 1.535% and 0.29% to 0.89%, respectively.
    Conclusions
    The prevalence of HBsAg and anti-HCV among blood donors suggests that our region has low endemicity for both hepatitis B and hepatitis C.

    Background
    Celiac disease (CD) is an autoimmune disease characterized by immunemediated inflammatory damage of the small intestinal mucosa، precipitated by the ingestion of gluten-containing foods. Since human leucocyte antigen DQ2 (HLA-DQ2) is a marker of nonresponsiveness to hepatits B virus (HBV) vaccine، CD may also be associated with this nonresponsiveness.
    Objectives
    The aim of this study was to compare the responses to HBV vaccine between children with CD and healthy children. We also investigated the relationship between the patients’ responses to hepatitis B vaccine، the clinical presentation of CD، and dietary compliance in the patients. Patients and
    Methods
    We recruited 52 children with CD and 20 age- and sex-matched healthy children who received HBV vaccination according to the standard immunization schedule. The production of specific antihepatitis B surface antigen (HBsAg) antibodies was evaluated in all patients and control participants. Subjects with less than 10 IU/L anti-HBs were considered nonresponders to the vaccination.
    Results
    31 of the 52 patients (59. 6%) were female and 21 (40. 4%) were male. The mean age of the CD patients was 10. 7 ± 4 years (range، 4–18 years). Anti-HBs titers were positive in 32 (61. 5%) patients and negative in 20 (38. 5%) patients، while they were positive in 18 (90%) of the children in the control group (P < 0. 05). We found statistically significant differences between negative anti-HBs titers، clinical presentation of CD، and dietary compliance in patients with CD (P < 0. 05).
    Conclusions
    Nonresponsiveness to hepatitis B vaccination was more frequently found in children with CD than in the control group. Therefore، the response to HBV vaccination should be investigated in children with CD، and a different immunization schedule may need to be developed. Further، compliance to the prescribed gluten-free diet (GFD) may improve the immune response to HBV vaccination in children with CD.

    Background
    Small studies have suggested that nucleos(t)ide analogue therapy (NAT) with reduced hepatitis B immunoglobulin (HBIG) duration may be efficacious in preventing post-liver transplantation (LT) HBV recurrence.
    Objectives
    This larger study evaluates the use of NAT with short term (< 6 mo) or no HBIG for prevention of post-LT HBV recurrence. Patients and
    Methods
    All HBV patients undergoing LT at a university transplant center between 2002 and 2007 were identified retrospectively. Patient demographics, medication regimen, and adverse events were noted. The primary endpoint was HBV recurrence and secondary endpoints were graft and patient survival.
    Results
    28 study patients were identified. Of these 28 patients, 4 (14%) received no HBIG, 6 (22%) received only inpatient HBIG, and 18 (64%) received inpatient HBIG and outpatient HBIG. 16 of the 28 patients (57%) received combination NAT and 12 patients (43%) received single NAT. At a median time of 15.5 months (range 9–24 months) post- LT, 4 of the 28 patients (14%) had recurrent HBV. Of those patients with recurrent HBV, 3 received both inpatient and outpatient HBIG and 1 received no HBIG. All cases of HBV recurrence were associated with noncompliance.
    Conclusions
    NAT with short-term or no HBIG was efficacious and safe in preventing post-LT HBV. All compliant patients were HBV-free, including 9 patients who received no HBIG or only inpatient HBIG. Additional studies using NAT without HBIG appear justified.

    Background
    Renal transplant recipients are known to be susceptible to viral infections, with more severe clinical presentations compared to healthy persons. Hepatitis E is generally a self-limited disease, which is caused by hepatitis E virus. Recently, hepatitis E has become more important in organ transplant recipients, because of new findings regarding the potential for chronic infections in this patient group.
    Objectives
    This study aimed to evaluate the seroprevalence of anti-HEV IgG among kidney transplant recipients in Urmia, in the north-western region of Iran.Patients and
    Methods
    91 patients were selected randomly from amongst patients who had undergone kidney transplantation in Urmia, Iran. Each patient was tested for the presence of anti-HEV IgG antibody using an enzyme-linked immunosorbent assay (ELISA, Dia.Pro; Diagnostic Bioprobes, Italy).
    Results
    28 subjects (30.8%) were seropositive for anti-HEV IgG. Seropositive patients were generally older than seronegative patients (P = 0.009). There was no correlation between HEV infection and the level of education (P = 0.206), the history of blood transfusion (P = 0.164), or history of pre-transplantation hemodialysis (P = 0.228). There was no significant difference in the serum alanine aminotransferase (ALT) levels of the anti-HEV seropositive and seronegative patients. Multinomial logistic regression analysis indicated no significant relationship between HEV infection and increase in ALT levels, even after controlling for treatment with azathioprine (P = 0.79, OR = 1.1; 95% CI: 0.45–2.76).
    Conclusion
    The anti-HEV IgG antibody has a high prevalence in Iranian kidney transplant recipients, and it is significantly higher in comparison with previous studies in the general population or in hemodialysis patients.

    Background
    Liver storage diseases are rare biochemical and inherited diseases that affect multiorgan systems.
    Objectives
    This study was performed to determine the rate of storage diseases and their types in liver pathology specimens of subjects who were referred to a tertiary pediatric center.Patients and
    Methods
    Two pathologists evaluated 2216 pathology specimens (stained with hematoxylin and eosin and periodic acid-Schiff) from subjects who were referred to the largest pediatric tertiary referral center in Iran between 1996 and 2007. Baseline data and clinical and laboratory manifestations were retrieved from the patients’ files.
    Results
    We identified 117 patients who had storage diseases. A combination of clinical and laboratory findings was used to assess the final diagnosis. Glycogen storage disease (GSD) was observed in 85 of cases, compared with lysosomal storage diseases (LSD) in 31 patients and mucopolysaccharidoses in 1 case. LSD was more prevalent in those aged between 1 month and 1 year, whereas GSD was more frequent in those aged between 1 and 6 years. Most of the patients aged between 1 and 6 years. Most patients with LSD and GSD had unknown types of the disease. The most common known types in the LSD and GSD groups were Niemann-Pick disease and GSD type I respectively. The most common clinical and laboratory manifestation was hepatomegaly and abnormal liver enzymes, respectively.
    Conclusions
    Most of our patients with storage diseases had Gaucher disease. Hepatomegaly and elevated transaminase levels were the most striking finding. However, with regard to the limitations of our methodology, further studies that collect more accurate data are warranted.

    Corticosteroids are used widely to treat many types of disease. In general, these drugs are considered safe for the liver; however, recent reports have demonstrated that highdose methylprednisolone (MT) may cause severe liver injury. Here, we report a case of a 24-year-old female who was given pulsed MT therapy for multiple sclerosis. MT induced icteric hepatitis and impaired liver synthetic function. Hepatotoxicity developed several weeks after drug exposure, and the causal association with MT was confirmed by unintentional rechallenge test. A brief review of the literature on corticosteroid- induced hepatotoxicity is presented.
