    Background
    Y-box binding protein 1 (YB-1) overexpression has been shown in various tumor cells including hepatocellular carcinoma (HCC); moreover، this protein can be actively secreted..
    Objectives
    The aim of this study was to establish a method to quantify serum YB-1 and evaluate its clinical application in the clinical diagnosis of HCC.. Patients and
    Methods
    Recombinant YB-1 and two populations of its antibodies were prepared. A monoclonal antibody was specific to the N-terminus of YB-1 amino acids 134-160; and another was a polyclonal antibody. A sandwich-type chemiluminescence immunoassay (CLIA) was developed and evaluated. Levels of YB-1 and alpha fetoprotein (AFP) in serum samples from 105 HCC patients، 25 hepatitis B virus patients، 25 cirrhosis patients، and 50 healthy donors were detected using the established method and an AFP electrochemiluminescence kit..
    Results
    The developed method was linear to 150 μg/L of YB-1 with a minimum detection limit of 0. 01 μg/L. The average recoveries were between 93. 9% and 109. 0%. The mean intra- and inter-assay coefficients of variation (CVs) were 4. 0-4. 8% and 8. 2-10. 2%، respectively. The relationship between the concentration of diluted YB-1 and the dilution ratios gave a good linear correlation coefficient of 0. 9986. The YB-1 concentration was increased in serum of HCC patients (33. 0 ± 23. 39 μg/L) compared to healthy individuals (13. 2 ± 5. 29 μg/L، P < 0. 0001)، patients with HBV (17. 9 ± 7. 49 μg/L، P = 0. 0003)، and patients with HBV cirrhosis (20. 7 ± 8. 75 μg/L، P < 0. 05). Moreover، the combination of YB-1 and alpha-fetoprotein had a high sensitivity (89. 5%) and reasonable specificity (62. 0%) in identifying HCC..
    Conclusions
    The established method has an acceptable performance in quantifying YB-1. In addition، serum YB-1 may aid in the diagnosis of HCC..

    Background
    Chronic HCV represents one of the common causes of chronic liver disease worldwide with Egypt having the highest prevalence, namely genotype 4. Interleukin IL-28B gene polymorphism has been shown to relate to HCV treatment response, mainly in genotype1..
    Objectives
    We aim to evaluate the predictive power of the rs12979860 IL28B SNP and its protein for treatment response in genotype 4 Egyptian patients by regression analysis and decision tree analysis..Patients and
    Methods
    The study included 263 chronic HCV Egyptian patients receiving peg-interferon and ribavirin therapy. Patients were classified into 3 groups; non responders (83patients), relapsers (76patients) and sustained virological responders (104 patients). Serum IL 28 B was performed, DNA was extracted and analyzed by direct sequencing of the SNP rs 12979860 of IL28B gene..
    Results
    CT, CC and TT represented 56 %, 25 % and 19% of the patients, respectively. Absence of C allele (TT genotype) was significantly correlated with the early failure of response while CC was associated with sustained virological response. The decision tree showed that baseline alpha fetoprotein (AFP ≤ 2.68 ng/ml) was the variable of initial split (the strongest predictor of response) confirmed by regression analysis. Patients with TT genotype had the highest probability of failure of response..
    Conclusions
    Absence of the C allele was significantly associated with failure of response. The presence of C allele was associated with a favorable outcome. AFP is a strong baseline predictor of HCV treatment response. A decision tree model is useful for predicting the probability of response to therapy..

    Background
    Hepatocellular carcinoma is a highly progressive cancer in the case of late diagnosis which is frequently associated with HBV and HCV viral infections..
    Objectives
    To identify differentially expressed serum proteins among three main stages of HCV infection and healthy individuals, and their comparisons with sera from patients with the same stage of HBV infection..Patients and
    Methods
    Two-dimensional polyacrylamide gel electrophoresis combined with liquid chromatography-tandem mass spectrometry was performed on 47 sera from healthy volunteers, those with chronic active hepatitis, cirrhosis and HCC patients associated with HBV and HCV infections..
    Results
    Among these, 62 spots were differentially expressed (≥ 1.5 fold; P < 0.05), of which 42 spots that corresponded to 15 proteins were identified by liquid chromatography-tandem mass spectrometry. CD5-like antigen (CD5L) was differentially expressed between cirrhosis and HCC patients with HCV infection. Leucine-rich α2-glycoprotein (LRG) and haptoglobin (HP) α2 isoforms differed in the HCC that was associated with either HCV or HBV infections..
    Conclusions
    CD5L might be a useful biomarker for early diagnosis of HCC in HCV cirrhotic patients. LRG and HP α2 isoforms could be potential markers for distinguishing viral HCC. Our results also further support the presence of varying molecules involved in hepatocarcinogenesis in HBV when compared with HCV infection..

    Background
    Hepatitis B virus (HBV) is one of the most common chronic viral infections in the world. Iran has a low to intermediate HBV prevalence and approximately 1.5 million people are living with HBV infection. The impact of HBV in Iran is unknown and given the very low levels of alcohol consumption, this region provides an opportunity to examine the impact of isolated chronic HBV infection..
    Objectives
    To examine and evaluate outcome and prognosis of HBV in Iran..Patients and
    Methods
    A longitudinal cohort study dating from 2003-2010 was performed. The patients were assessed six months after their first visit and then during periodic visits for the subsequent seven years. The patients’ medical history, route of diagnosis of infection, family history, and liver diseases status including: carrier state of HBV, chronic HBV, cirrhosis, and HCC were recorded. Descriptive and analytic statistics were performed, using SPSS software version 18..
    Results
    275 HBsAg positive patients, who had completed a 7 year follow up period, were selected. The annual incidence rate for chronic hepatitis B in inactive carrier states and cirrhosis were 0.46% and 0.2% respectively. Over seven years, the rate of inactive carriers decreased by eight percent (They turned into chronic HBV or became HBSAg negative). No significant association was found between HBSAg seroclearance, HBeAg seroconversion and the outcome in the end of each year of follow up. Different treatment regimens did not have any statistically significant difference regarding HBeAg seroconversion. There was no significant association between the outcome and different habitual characteristics, especially smoking, as well as family history on HBsAg, HBsAb, HBeAg, and Anti-HBeAg. Values of platelets and ALT showed a significant change during the follow ups. Annual incidence rate of HCC in the present study was in the range of other studies..
    Conclusions
    These data confirm and extend data from other populations showing a low incidence of significant change in chronic HBV infection in short term with good responses to currently available therapeutics..

    Background
    Liver transplantation is considered as the standard treatment for both children and adults with end-stage liver diseases. Using this method, children who have no chance for life can live a much longer life. Shiraz Transplant Center is the major pediatric liver transplant center in Iran. Therefore, determining patients’ survival and its effective factors can help clinical programming for increasing such patients’ survival after liver transplantation..
    Objectives
    The present study aimed to investigate the survival of patients below-18-years-old undergoing liver transplantation and the factors affecting their survival..Patients and
    Methods
    The present historical cohort study was conducted on 392 patients below-18-year-sold who had undergone liver transplantation for the first time in the Namazi hospital liver transplant center, Shiraz, Iran between 2000 and 2011. In this study, 1-, 3-, 5-, and 10-year survival of the patients was assessed using Kaplan-Meier and life table methods. The effect of factors related to the recipients, donors, and the transplantation process on the patients’ survival was also investigated..
    Results
    According to the results, 1, 3, 5 and 10-year survival of patients was 73%, 67%, 66%, and 66%, respectively. Besides, 1, 3, 5, and 10-year survival of the patients who survived 1 and 3 months after the transplantation was 84%, 78%, 77%, and 77% and 89%, 82%, 81%, and 81%, respectively. In the univariate analysis, age, patients’ weight at transplantation, initial diagnosis, PELD/MELD score, existence of post-transplant complications, and year of transplantation were found to be effective factors on the patients’ survival. In the multivariate analysis, only the type of graft, PELD/MELD score, and existence of post-transplant complications were the prognostic variables..
    Conclusions
    In this study, the patients’ survival rate was 73%, which is quite low compared to the survival rate reported in other studies. Although we only have a 12-year experience with pediatric liver transplantation, the survival rate has increased in our center through the recent years (2008-2011). However, the survival rate of the patients who had survived 3 months after the transplantation was 89% which is comparable to other studies. Overall, cholestatic diseases (biliary atresia was the most prevalent), type of transplantation (split), PELD/MELD score > 20, and existence of post-transplant complications increased the risk of death after the transplantation..

    Background
    Dietary intake might have important role in non-alcoholic fatty liver diseases (NAFLD). Although, there are some reports on dietary intake and anthropometrics measurements, few studies have focused on the markers of assessing whole diet like dietary quality indices..
    Objectives
    Therefore, our aim was to determine the diet quality indices and biochemical parameters among patients with NAFLD and healthy individuals..Patients and
    Methods
    This case-control study was performed on 100 patients with NAFLD and 100 healthy subjects who were attending to Gastrointestinal Research Center, Baqiyatallah University, Tehran, Iran during the recent years. Usual dietary intake was assessed by three dietary records (one weekend and two week days). Healthy eating index (HEI), dietary diversity score (DDS), dietary energy density (DED), mean adequacy ratio of nutrients (MAR) were assessed according to the standard methods..
    Results
    Patients with NAFLD had higher body mass index, weight and waist circumference compared to the healthy group (P < 0.05). Serum levels of liver enzymes, triglyceride, LDL, BUN, and uric acid were higher in patients with NAFLD (P < 0.05). Although patients with NAFLD had higher energy, carbohydrate and fat intake, their values for antioxidant vitamins, calcium and vitamin D were lower than healthy subjects (P < 0.05). HEI and MAR were higher among healthy group, and DED was lower among them. Nutrient adequacy ratio for calcium, vitamin D, and antioxidant micronutrients were lower in patients with NAFLD (P < 0.05)..
    Conclusions
    It seems that dietary quality indices may be associated with NAFLD. Calcium, vitamin D, and antioxidant micronutrients intake might be lower among patients with NAFLD based on this case-control study. Further prospective studies should be conducted in this regard..
