    Background
    Non-alcoholic fatty liver disease (NAFLD) is the most prevalent liver disorder in western countries and an important cause of liver cirrhosis, as well as liver failure. Up to now, 20‒40% of the individuals suffer from this disorder and its prevalence is estimated around 5‒30% in Asia. The NAFLD is one of the most prevalent causes for increases in liver enzymes and has a close relationship with obesity, dyslipidemia, hypertension, and type II diabetes. However, no definite treatment has been identified for it yet..
    Objectives
    The present study aimed to investigate the effect of berberis vulgaris extract in inducing changes in liver enzymes levels..Patients and
    Methods
    The present clinical trial was conducted on 80 patients, including 32 males (40%) and 48 females (60%), who were randomly assigned into two groups of case and control. All the patients had ultrasound evidence of lipid accumulation in the liver and increases in liver enzymes. The case group received two capsules (750 mg) containing berberis vulgaris extract every day for 3 months, while the control group was treated with placebo. The weight, liver transaminases levels and lipid profiles of the two groups were assessed before, during, and after the study..
    Results
    In the case group, the mean serum levels of alanine transaminase (ALT) and aspartate transaminase (AST) decreased from 49 to 27.48 and 48.22 to 29.8 u/L, respectively, which was statistically significant compared to the control group (P < 0.001, P < 0.001). In the control group, the mean of ALT and AST decreased from 50.4 to 46.8 and 45.7 to 44.9 u/L, respectively. The difference was not statistically significant. In addition, a significant decrease was observed in weight, triglycerides, and cholesterol, while no significant change was found in fasting blood sugar, high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL)..
    Conclusions
    Considering the significant decrease in the liver enzymes, triglycerides and cholesterol after using berberis vulgaris extract, further studies with larger sample sizes will identify the accurate dose as well as duration of consumption for this extract, to recommend in the treatment of patients with NAFLD..

    Background
    Hepatitis C virus (HCV) infection is a major blood-borne infection with silent epidemic, major global public health problem and diverse prevalence worldwide..
    Objectives
    This study aimed to evaluate the prevalence of HCV infection and related risk factors in the general population of two villages, Farmashkan and Akbarabad, of the Kavar City in Fars Province, Iran..Patients and
    Methods
    A 34-month cross-sectional study was performed on all people of the villages aged ≥ 7 years from July 2007 to April 2010. Demographic information and history of HCV-related risk factors were extracted from their medical records. For each participant, the serum anti-HCV IgG was assessed by the commercial enzyme-linked immunosorbent assay (ELISA) kits..
    Results
    A total of 6095 participants (36.4% male and 65.6% female) with the mean age of 92 (7-95) and mean ± SD of 34.6 ± 17.3 years were included in this study. Fifteen persons (0.24%) were detected as HCV-positive and the highest prevalence was seen in age ≤ 12 years old (1%). A significant association was only detected between blood transfusion and HCV infection; therefore, those persons with history of blood transfusion had 15-fold higher risk for HCV seropositivity (odds ratio 15.54, 95% CI = 4.89-49.41)..
    Conclusions
    Our reported rate of HCV seropositivity is similar to the previous Iranian reports. However, future evaluations should be focused on the Polymerase Chain Reaction method for the detection of HCV and determining and evaluating of other related risk factors. Moreover, more attention should be paid to blood donors as a reservoir population of HCV..

    Background
    Finding a noninvasive method to predict liver fibrosis using inexpensive and easy-to-use markers is important..
    Objectives
    We aimed to clarify whether NX-des-γ-carboxyprothrombin (NX-DCP) could become a new noninvasive model to predict liver fibrosis in hepatitis C virus (HCV) related liver disease..Patients and
    Methods
    We performed a prospective cohort study on a consecutive group of 101 patients who underwent liver biopsy for HCV-related liver disease at Kobe University Hospital. Laboratory measurements were performed on the same day as the biopsy. Factors associated with significant fibrosis (F3-4) were assessed by multivariate analyses. A comparison of predictive ability between multivariate factors and abovementioned noninvasive models was also performed..
    Results
    Increase in serum NX-DCP was significantly related to increase in fibrosis stage (P = 0.006). Moreover, NX-DCP was a multivariate factor associated with the presence of significant fibrosis F 3-4 (median 21 of F0-2 group vs. median 22 of F3-4 group with P = 0.002). The AUC of NX-DCP showed no significant differences compared with those of the AST-to-platelet ratio index (APRI), modified-APRI, the Göteborg University Cirrhosis Index (GUCI), the Lok index, the Hui score, cirrhosis discriminating score (CDS) and the Pohl score (P > 0.05)..
    Conclusions
    NX-DCP correlated positively with fibrosis stage and could discriminate well between HCV-related patients with or without significant fibrosis. Moreover, NX-DCP had a similar predictive ability to the abovementioned models, and thereby could be a new noninvasive prediction tool for fibrosis..

    Background
    The molecular mechanism of hepatitis C-virus (HCV) genome-specific pathogenesis remains unclear. Oxidative stress is an important pathophysiological mechanism in chronic HCV infection, but its relation to HCV genotypes has not been thoroughly examined..
    Objectives
    In the present case-control study, the effect of diverse HCV genotypes on oxidative status changes was investigated.. Patients and
    Methods
    From 310 patients examined by enzyme immunoassay and PCR, 160 patients with positive results for HCV with previously determined genotypes were chosen. For the control group, 160 first time blood donors referred to the Regional Blood Transfusion organization of the West Azerbaijan province, northwestern Iran were selected. Oxidative stress markers such as total antioxidant status (TAS), serum levels of reduced (GSH) and oxidized (GSSG) glutathione, Gamma-glutamyl transferase (GGT) and malondialdehyde (MDA) were evaluated in patients infected with diverse HCV genotypes and those in the control group..
    Results
    In the patient and control groups, the mean ± SE of TAS, GSH, GSSG, GGT and MDA were 1.04 ± 0.35 vs. 2.68 ± 0.77, 1.25 ± 0.37 vs. 3.12 ± 0.58, 0.20 ± 0.05 vs. 0.08 ± 0.04, 26.82 ± 5.62 vs 8.28 ± 2.03 and 2.56 ± 0.60 vs. 0.93 ± 0.34. All markers had statistical difference between the two groups (P <0.05). Obvious differences were found in oxidant/antioxidant balance among diverse HCV genotypes with an ascending trend in antioxidant levels among patients infected with genotypes 1a/b, 4, 2a/c, 2b, 3a and healthy controls and a vice versa trend in measures of oxidative markers except for malondialdehyde with a variable pattern..
    Conclusions
    More serious disease in HCV genetic subtype 1a/1b might be associated with more severe oxidative stress. Milder damage in subtypes 4, 2a/c, 2b and 3a could be related to lower oxidative response, respectively. A combination of antiviral and antioxidative therapies may enhance the overall response rate of patients with HCV infection, especially with more destructive genotypes.

    Background
    In patients with chronic hepatitis C, triple drug regimens containing a protease inhibitor, peginterferon and ribavirin were found to significantly increase sustained virologic response rates compared to dual drug regimen containing pegylated interferon and ribavirin, especially in genotype 1..
    Objectives
    In Turkey, telaprevir has been used since March 2013. We aimed to evaluate results of patients with chronic hepatitis C treated with telaprevir, peginterferon and ribavirin.. Patients and
    Methods
    We evaluated 28 patients with genotype 1 chronic hepatitis C infection treated with triple drug regimen containing telaprevir, in three medical centers in Turkey, retrospectively. Demographic data of patients, treatment indications, adverse events and outcomes were recorded..
    Results
    Of 28 patients intended to treat, 25 (89.2%) patients completed the treatment. Overall, 21 (82.1%) patients had relapse and five patients were non-responder. Regarding the treatment outcomes of Telaprevir based regimen, 20/26 patients achieved sustained virological response. Pruritus, rash, dysgeusia, anorectal discomfort and anemia were main adverse effects. Blood transfusion and ribavirin dose reduction required for 7 and 11 patients, respectively. Due to several adverse effects, 10 patients were hospitalized..
    Conclusions
    Although more frequent and severe adverse effects, telaprevir has been promising for patients with treatment-experienced hepatitis C..

    Background
    Although certain HBV mutations are known to affect the expression of Hepatitis e antigen, their association with HBV viral level or clinical outcomes is less clear..
    Objectives
    We evaluated associations between different mutations in the Basal Core promoter (BCP) and Pre-core (PC) regions of HBV genome and subsequent changes in HBV viral DNA level over seven years in a population of untreated HBeAg negative chronic hepatitis B (CHB) participants in Northeast of Iran..
    Materials And Methods
    Participants in the current study were drawn from the Golestan Hepatitis B Cohort Study (GHBCS), a cohort of approximately 2590 HBsAg positive subjects (living in Gonbad city) embedded in the Golestan Cohort Study (GCS). At baseline, HBsAg was measured in all participants and revealed 2590 HBsAg positive cases. We randomly selected 304 participants who their blood sample were taken at both baseline and seven years later in follow-up and had not been treated for HBV during this time. HBV viral load were assessed at baseline and at year 7. The BCP and PC regions of the HBV DNA, at baseline, were amplified via hemi-nested PCR and sequenced by cycle sequencing. At year 7, liver stiffness was assessed by fibroscan; also, other parameters of liver disease were assessed following standard clinical protocols. Associations were assessed via tabulation, chi-square, t-tests and logistic regression. P values < 0.05 were considered statistically significant and all tests were two-sided..
    Results
    Among 304 HBsAg positive participants, 99 had detectable HBV DNA at study baseline. Of these, 61.6% had PC mutations (48.5% A1896 and 25.2% G1899). In contrast to other mutations, A1896 was associated with a higher proportion of detectable HBV DNA at year 7 (39.6%) compared to patients with the wild type (13.7%) (OR: 4.36, CI95% = 1.63-11.70; P Value = 0.002). Although participants with the A1896 mutation had higher year-7 HBV viral load than participants with G1896 (2.30 ± 1.66 IU/mL vs. 1.76 ± 1 IU/mL among patients with detectable HBV; P value = 0.052), no association was observed with either serum level ALT or liver stiffness. Interestingly, mutations in the basal core promoter (BCP) region had no significant effect on virus DNA detection..
    Conclusions
    In this population with chronic HBeAg negative hepatitis B, an association was observed between the G1896A mutation in the Pre-core region of HBV and subsequent level of HBV DNA seven years later, which indicated that mutations in this region of HBV genome may contribute to disease progression in these patients and play an important role in HBV natural course of disease..

    Background
    Liver is one of the most important organs affected by exercise. According to the literature a few study to date has investigated the effects of estrogen supplementation on exercise-induced oxidative stress in liver tissue of rats..
    Objectives
    We aimed to investigate the effects of estrogen supplementation on oxidative stress markers in liver tissue of exercised rats..
    Materials And Methods
    Male rats (n = 35) were divided as estrogen supplemented (n = 18) and non-supplemented groups (n = 17); these groups were further divided as rest and eccentric exercised groups. Eccentric exercise groups were further divided as rats killed after 1 hour and 48 hours of eccentric exercise. Estrogen (10 mg/kg) was administered subcutaneously for 30 days. Eccentric exercise was applied as treadmill run (15° downhill, 20 m/min) consisting of periods of «5 min» run and 2 min rest repeated 18 times. The rat liver was examined biochemically and histologically. Activities of GST, GSH-Px, CAT, SOD and MDA concentration were also measured spectrophotometrically..
    Results
    Some disruptions were detected in experimental groups compared with the control group. Additionally, exercise training caused an increase in SOD and decrease in GSH-Px activities in some experimental groups. SOD activities increased significantly in group 3 (Estrogen (-), eccentric exercise (+) killed (after 1 h), compared with group 5 (Estrogen (-), eccentric exercise (+) killed (after 48 h). On the other hand, GSH-Px activities were also significantly decreased in groups 3, 4 and 5 compared with the control group. Leukocyte infiltration in liver increased after 48 hours compared with after 1 hour and estrogen supplementation was not able to prevent this infiltration..
    Conclusions
    Estrogen seemed to be not very effective to prevent eccentric exercise-induced liver damage..
