Abstract
Hepatitis C virus (HCV) infection is a global health concern affecting millions worldwide. Chronic HCV infection often leads to liver inflammation and can progress to cirrhosis and hepatocellular carcinoma. Inflammatory cytokines are crucial in modulating the immune response during HCV infection. This review aims to investigate the impact of different inflammatory cytokines on HCV infection and associated immune responses. This review was conducted to identify relevant studies on the interplay between inflammatory cytokines and HCV infection. The analysis focused on the effects of key inflammatory cytokines, including tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), interleukin-1 (IL-1), and interferon-gamma (IFN-γ), on HCV replication, immune cell activation, and liver inflammation. The findings reveal that these inflammatory cytokines can significantly influence HCV infection and the subsequent immune response. TNF-α, IL-6, and IL-1 have been shown to enhance HCV replication, while IFN-γ exerts antiviral effects by inhibiting viral replication and promoting immune cell-mediated clearance of infected hepatocytes. Moreover, these cytokines contribute to the recruitment and activation of immune cells, such as natural killer cells, T cells, and macrophages, which play critical roles in controlling HCV infection. Understanding the precise mechanisms by which inflammatory cytokines impact HCV infection is crucial for developing more targeted therapeutic strategies. Modulating the levels or activity of specific cytokines may provide opportunities to attenuate HCV replication, reduce liver inflammation, and improve treatment outcomes. In conclusion, this review highlights the significance of inflammatory cytokines in influencing HCV infection and associated immune responses.

Abstract
BACKGROUND Sustained virologic response (SVR) rates after directly acting antivirals (DAAs) for hepatitis C virus (HCV) exceed 95%. This encouraged policymakers to put plans to achieve HCV elimination by 2030. The remaining percentage of non-SVR12 can affect HCV eradication strategies in the real-world especially the compliance of large numbers of treated persons to follow up for assessment of virologic response cannot be guaranteed. OBJECTIVE We aimed to assess predictors of failure to achieve SVR after receiving sofosbuvir plus NS5A inhibitor as an important step towards achieving better HCV eradication strategies. METHODS During the period from 1st November 2018 to 1st November 2019, 1581 treatment-naive patients received sofosbuvir plus daclatasvir ± ribavirin at our unit and 10 patients were referred to us with HCV relapse after the same regimens. A total of 163 out of the 1581 patients were lost for follow-up before assessment of virologic response and excluded from the analysis. 20 out of the remaining patients failed to achieve SVR12. Data from the 30 patients with non-SVR12 were included in the case-control analysis. RESULTS Every unit increase in estimated creatinine clearance using modification of diet in renal disease study (MDRD) score, total bilirubin, and INR was associated with 1.03, 13.92, and 80.08 times greater odds of non-SVR12 (P<0.001, P=0.0016, P=0.02) respectively. The presence of liver cirrhosis on ultrasonography increases the odds by 10.03. (P=0.009). CONCLUSION Higher MDRD score, INR, total bilirubin, and presence of sonographic features of liver cirrhosis are predictors of failure to achieve SVR12 using sofosbuvir plus NS5A inhibitor.

Abstract
Abstract
Background
Chronic hepatitis C (CHC) is a silent viral infection; however, elevated mortality and morbidity rates are noted in Egypt due to its adverse effects. The augmented incidence of diabetes in patients with viral C infection may be owing to glucose intolerance, high BMI, senility, and inherited factors.
Purpose of the study
Little information is available about the connection between interleukin-28B (IL-28B) genotype in disease progression among CHC patients with diabetes. Thus, we aimed to assess the association between IL-28B genotype (rs12979860) in CHC with type 2 diabetes mellitus (T2DM) versus those without diabetes in disease progression among Egyptian patients.
Results
CC genotype was significantly lower in diabetics than in non-diabetics (13.7% vs. 36.3%). While (CT/TT) were significantly higher in diabetics than in non-diabetics (CT 58.8% vs. 43.7%), (TT 27.5% vs. 20%) (p = 0.03) and likewise alleles (p = 0.04). Multivariate logistic regression analysis was significant with viral load p < 0.001, alanine aminotransferase (ALT) p < 0.001, genotype CC versus TT p = 0.04 & T2DM p = 0.03.
Conclusion
CC genotype might be used as a protective factor and TT genotype as a risk factor in disease progression among CHC patients with T2DM. Additionally, viral load, ALT & T2DM might interplay as predictors of disease severity. Detecting the genetic factors can be helpful in predicting and preventing the complications of diabetes associated with the hepatitis C virus (HCV).

Abstract
BACKGROUND Chronic hepatitis C (CHC) is a leading cause of cirrhosis and hepatocellular carcinoma (HCC). This study aimed to study the association of IL28B, toll-like receptor (TLR) 7, cytomegalovirus and advanced liver disease. METHODS Four groups were included; control (n = 125, 25.9%), CHC (n = 114, 23.6%), liver cirrhosis (n = 120, 24.8%), and HCC (n = 124, 25.7%). RESULTS In CHC group, patients were mainly F1 (60%) followed by F2. IL28B genotype CC percentage was higher in control group than the CHC and cirrhosis groups. CT and TT genotypes were higher in the CHC and cirrhosis groups than control group. The C allele was higher in the control group than the CHC, cirrhosis and HCC groups and the opposite with the T allele. Control and CHC had same TLR7 alleles. Cirrhosis patients and HCC had lower TLR 7 A allele and higher G allele than the control group. Both cirrhosis and HCC groups had statistically significant higher percentage of the AG and GG genotypes than the control group. Patients with HCC had higher cytomegalovirus infection percentage than cirrhosis and CHC group (38.7% vs 20% vs 16.7%), respectively. CONCLUSION IL28B, TLR7 SNPs and cytomegalovirus infection are risk factors for advanced liver disease in hepatitis C patients.

Abstract
BACKGROUND Complex diseases such as fibrosis are likely polygenic. Lately, cirrhosis risk score (CRS) clearly discriminated Chronic HCV patients with high-risk versus those with low-risk for cirrhosis better than clinical factors. METHODS Herein, the CRS was assessed via genotyping by allelic discrimination assays in 243 HCV Egyptian patients categorized into 164 patients didn't develop HCC (93 mild, 71 advanced fibrosis); and 79 patients developed HCC. APRI and FIB-4 scores were calculated, compared with CRS and correlated with degree of fibrosis progression. RESULTS Median of the three CRS, APRI and FIB-4 scores were significantly elevated in late fibrotic and HCC patients (p < 0.001); however CRS displayed proper discrimination (mild fibrosis (0.59; 0.4-0.75), advanced fibrosis (0.75; 0.7-0.86) and HCC (0.73; 0.57-0.77); (p < 0.001)). The ROC analysis of CRS score displayed modest accuracy to discriminate between mild and advanced fibrotic patient; AUC was 0.73; p < 0.0001), while AUC was only 0.57 (p = 0.05) for the discrimination between HCC and no HCC. Moreover, the combination of CRS, APRI and FIB4 lessened the power of correlation (AUC, 0.63 (p < 0.0001)) in fibrosis prognosis. In HCC prognosis, the combination of CRS, APRI and FIB4 in HCC patients showed modest accuracy with AUC, 0.59 (p = 0.0001). CONCLUSION The diagnostic accuracy of FIB-4 for predicting liver fibrosis was nearly identical to that of CRS, however the strength of CRS score stemmed from that it is built on 7 SNPs host genetic factor. Our study validates non invasive algorithms for fibrosis prognosis purposes which may aid in decision making for therapeutic intervention.

Abstract
Background: Single nucleotide polymorphisms (SNPs) of the interferon lambda 3 (IFN-λ 3) gene are associated with viral clearance and treatment response in chronic hepatitis C virus (HCV) infection. Aim: to assess whether specific IFN-λ 3 gene SNP, known as rs12979860 (C > T), could predict the outcome of treatment with direct acting antivirals (DAAs) among Egyptian patients with chronic HCV genotype 4 infection. Methods: Tetra-primer (ARMS-PCR) and PCR-RFLP methods were used for SNP genotyping in 100 chronic HCV-infected patients and 50 healthy subjects as control group. Results: The CC (wild type) genotype of rs12979860 was identified in 20 patients, 50% of them achieved sustained virological response (SVR). SNP genotype TT was found in 17 patients and only 2 of them (11.76%) were responders. The frequency of CT genotypes was significantly higher in responders than in non-responders (p= .021). In contrast, the frequency of TT genotypes was significantly higher in non-responders (42.85%, p< .001). On univariate and multivariate logistic regression analyses of the significant predictors of SVR, there were six predictive factors (Age, diabetes mellitus, AST, albumin, type of therapy and IFN-λ 3 genotype). Conclusion: The TT genotype and T allele were significantly associated with failure to achieve SVR. However, CT genotype of IFN-λ 3 (rs12979860) may be considered as a predictor for SVR in patients who received DAAs.

Abstract
Background: Despite the outstanding results of direct-acting antiviral therapies (DAAs) of Hepatitis C infection (HCV), non-responders had to be more defined. Aim: assess the outcome of DAAs in linkage with Interferon lambda 3 (IFNL3) in HCV patients. Methods: This case-control-study was conducted on 495 chronic-HCV (genotype-4a), previously treated Egyptians by either DAAs (responders 195, 120 relapsers) or interferon/ribavirin (IFN/RBV) (140 responders, 60 relapsers), and 98 healthy controls. IFNL3 distribution, clinical and laboratory data were assessed. Results: CT was the most predominant genotype in Egyptians (51%). All genotypes were sensitive to DAAs mainly CT genotype (60%), even TT genotype (resistant to IFN/RBV 40%) had 29.2% sensitivity. CT genotype was predominant in sofosbuvir/Daclatasvir responders (67.6%) (OR = 0.66), while non-CT prevailed in relapsers (56.7%). TT genotype may respond to SOF/Ledi better than other regimens (66.7%). In IFN/RBV relapsers; CT genotype was commoner (50%) than others, while CC genotype predominated in responders (54.3%). The c allele was the commonest in responders to IFN/RBV (71.4%), while the T allele was resistant to treatment (65% in relapsers). Addition of RBV to SOF/DCV reported higher resistance with CT genotype (42.2%-50%) and TT genotype (17.8%-27.8%). Conclusion: This study recommended IFNL3 genotyping to be a prerequisite before stratifying treatment for HCV-4a Egyptians.

Abstract
Background The association between interferon lambda-3 (IFNL3,also known as interleukin 28B, IL28B) rs12979860 polymorphism and the development of hepatocellular carcinoma (HCC) has been investigated in recent studies with inconclusive and inconsistent results. IFNL3 rs12979860 polymorphism has been shown a marked differential distribution with regional and ethnic variation. Whether this single nucleotide polymorphism influences susceptibility to hepatitis C virus (HCV)-related HCC remains elusive. Methods In this case–control study, a total of 157 Chinese Han patients with chronic HCV infection were enrolled, including 62 HCV-related HCC patients and 95 chronic hepatitis C (CHC) patients without HCC, and the genetic polymorphism of IFNL3 rs12979860 was genotyped via a DNA microarray-based assay. The logistic regression analysis was employed to determine the correlation between the genetic polymorphism and risk of HCV-related HCC. Results A higher proportion of CT/TT genotype and T allele was observed in HCC patients compared to the CHC group. Under the genetic model of allele frequency, the T allele was associated with elevated risk of HCV-related HCC in the Chinese population compared to C allele after an adjustment for age, gender, body mass index, HCV infection duration, and HCV genotypes (P=0.046). In the subgroup analysis stratified by HCV genotype, subjects with CHC genotype 1b infection carrying rs12979860 T allele and CT+TT genotype had higher susceptibility to HCC than those with C allele and CC genotype (P=0.020, P=0.037, respectively). Conclusion IFNL3 rs12979860 polymorphism with T allele could be a factor that increases the risk of HCV-related HCC in the Chinese population, especially those subjects with CHC genotype 1b infection.

Abstract
Hepatitis C virus (HCV) infection is a considerable public-health problem and an important cause of liver disease with about 71 million people infected worldwide and more than 399 000 people die every year from hepatitis C-related liver diseases. The present study was, therefore, initiated to investigate the association of polymorphism in interferon λ3 (IFNL3) also known as interleukin-28B (IL-28B) gene with chronic HCV infection and association of these polymorphic variants with the combination daclatasvir and sofosbuvir HCV therapy response. Genotypes were determined by the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay in a total of 250 chronic HCV genotype three patients and 500 number of healthy controls. Our data revealed that the TT (minor) genotype of IFNL3 (rs12979860) and GG (minor) genotype of IFNL3 (rs8099917) exhibited a significant association with chronic HCV genotype 3 infection when compared with controls. The results of treatment response showed that CC (major) genotype of IFNL3 (rs12979860) and TT (major) genotype of IFNL3 (rs8099917) are associated with the likelihood of achieving a higher sustained virological response (SVR), to combined daclatasvir and sofosbuvir therapy, in genotype 3-infected HCV patients, whereas the individuals with TT (minor) genotype of IFNL3 (rs12979860) and GG (minor) genotype of IFNL3 (rs8099917) are more susceptible to chronic HCV infection and treatment relapse, suggesting a role of IFNL3 (rs12979860) and (rs8099917) in the treatment outcome of combined daclatasvir and sofosbuvir therapy in chronic HCV genotype 3 infection.

Abstract
AIM The correlation of IL28-B genetic variants (rs12979860) with combinational therapy (peg-interferon, sofosbuvir plus ribavirin) of hepatitis C virus infection were studied in 154 chronic hepatitis C patients. METHODS & RESULTS The sustained virological response for efficient antiviral regimen was achieved in 75.32% treated individuals. Three genotypes of rs12979860 (CC, CT and TT) were compared both in sustained virological response and nonresponders groups (p = 0.25, p ≤ 0.001, p = 0.10, respectively). CT genotype demonstrated a significant correlation (p ≤ 0.001) in both groups with higher positive predictive value (81.55%). CONCLUSION IL28 polymorphism and positive predictive value may be considered as the markers for the evaluation of the effectiveness of the treatment regimen. Further clinical trials are recommended to verify the role of IL28-B in hepatitis C virus treatment.

Abstract
BACKGROUND A single nucleotide polymorphism (SNP) in the interleukin 28B (IL28B) gene may alter the trajectory of hepatitis C virus (HCV) chronic infection. Several studies have sought to determine a link between IL28B rs12979860 SNP and the development of HCV-related hepatocellular carcinoma (HCC), but with variable results, and consensus is awaited. We hypothesised that IL28B rs12979860 SNP is linked to HCC in patients with HCV type 4. METHODS IL28B genotyping of 300 patients with HCV-related fibrosis (n = 100), cirrhosis (n = 100) and HCC (n = 100) was carried out and the results were analysed to determine the association between the IL28B genotype and clinical outcome. RESULTS In IL28B TT genotype carriers, the proportions of moderate/severe fibrosis, advanced cirrhosis (Child B-C) and HCC (50%, 84% and 60.2%, respectively) were higher (p < 0.05) than in CC/CT (4.3%, 46% and 23%, respectively). IL-28B SNP was linked significantly (p < 0.05) with cirrhosis progression and HCC advanced stages. Moreover, HCC advanced Child, Okuda and CLIP stages were associated with T allele carriage (73.9%, 82.6% and 78.3% vs. 44.2%, 50.6% and 46.8% in CC/CT). The percentage of large tumour size (> 3cm) increased (p = 0.028) in TT genotype carriers (81.8% vs.52.6% in CC/CT). CONCLUSION IL-28B rs12979860 TT genotype is more prevalent in patients with advanced fibrosis, cirrhosis and HCC stages. Thus, it seems to be associated with poor outcomes in chronic HCV patients and to augment the risk of developing HCC.

Abstract
Hepatitis C virus (HCV)-infected patients are at risk of developing hepatocellular carcinoma (HCC). Individuals at heightened risk could be targeted by intensive follow-up surveillance. We have conducted a systematic review of the literature to identify host genetic predisposition to HCC in HCV-infected patients. A comprehensive search of Medline and Embase databases was performed, and the strength of evidence of associations for each gene on development of HCC was evaluated. We identified 166 relevant studies, relating to 137 different genes, or combinations thereof. Seventeen genes were classified as having "good" evidence of an association, a significant association was observed for 37 genes but this finding had not yet been replicated, 56 genes had mixed or limited evidence of an association, and 27 genes showed no association. IFNL3/4, TNF-α and PNPLA3 genes had the most evidence of an association. There was, however, considerable heterogeneity in study design and data quality. In conclusion, we identified a number of genes with evidence of association with HCC, but also a need for more standardized approaches to address this clinically critical question. It is important to consider the underlying mechanism of these relationships and which are confounded by the presence of other HCC risk factors and response to therapy. We also identified many genes where the evidence of association is contradictory or requires replication, as well as a number where associations have been studied but no evidence found. These findings should help to direct future studies on host genetic predisposition to HCC in HCV-infected patients.

Abstract
IL28B single nucleotide polymorphism (rs12979860) is an etiology-independent predictor of hepatitis C virus (HCV)-related hepatic fibrosis. Data mining is a method of predictive analysis which can explore tremendous volumes of information from health records to discover hidden patterns and relationships. The current study aims to evaluate and compare the prediction accuracy of scoring system like aspartate aminotransferase-to-platelet ratio index (APRI) and fibrosis-4 (FIB-4) index versus data mining for the prediction of HCV-related advanced fibrosis. This retrospective study included 427 patients with chronic hepatitis C. We used data mining analysis to construct a decision tree by reduced error (REP) technique, followed by Auto-WEKA tool to select the best classifier out of 39 algorithms to predict advanced fibrosis. APRI and FIB-4 had sensitivity-specificity parameters of 0.523-0.831 and 0.415-0.917, respectively. REPTree algorithm was able to predict advanced fibrosis with sensitivity of 0.749, specificity of 0.729, and receiver operating characteristic (ROC) area of 0.796. Out of the 16 attributes, IL28B genotype was selected by the REPTree as the best predictor for advanced fibrosis. Using Auto-WEKA, the multilayer perceptron (MLP) neural model was selected as the best predictive algorithm with sensitivity of 0.825, specificity of 0.811, and ROC area of 0.880. Thus, MLP is better than APRI, FIB-4, and REPTree for predicting advanced fibrosis for patients with chronic hepatitis C.

Abstract
AIM To investigate the association of tumor necrosis factor alpha (TNFα) -G308A polymorphism with different liver pathological changes in treatment-naïve Egyptian patients infected with hepatitis C virus (HCV) genotype 4.
METHODS This study included 180 subjects, composed of 120 treatment-naïve chronic HCV patients with different fibrosis grades (F0-F4) and 60 healthy controls. The TNFα -G308A region was amplified by PCR and the different genotypes were detected by restriction fragment length polymorphism analysis. The TNFα protein was detected by enzyme-linked immunosorbent assay. The influence of different TNFα -G308A genotypes on TNFα expression and liver disease progression were statistically analyzed. The OR and 95%CI were calculated to assess the relative risk confidence.
RESULTS Current data showed that the TNFα -G308A SNP frequency was significantly different between controls and HCV infected patients (P = 0.001). Both the AA genotype and A allele were significantly higher in late fibrosis patients (F2-F4, n = 60) than in early fibrosis patients (F0-F1, n = 60) (P = 0.05, 0.04 respectively). Moreover, the GA or AA genotypes increased the TNFα serum level greater than the GG genotype (P = 0.002). The results showed a clear association between severe liver pathological conditions (inflammation, steatosis and fibrosis) and (GA + AA) genotypes (P = 0.035, 0.03, 0.04 respectively). The stepwise logistic regression analysis showed that the TNFα genotypes (GA + AA) were significantly associated with liver inflammation (OR = 3.776, 95%CI: 1.399-10.194, P = 0.009), severe steatosis (OR = 4.49, 95%CI: 1.441-14.0, P = 0.010) and fibrosis progression (OR = 2.84, 95%CI: 1.080-7.472, P = 0.034). Also, the A allele was an independent risk factor for liver inflammation (P = 0.003), steatosis (P = 0.003) and fibrosis (P = 0.014).
CONCLUSION TNFα SNP at nucleotide -308 represents an important genetic marker that can be used for the prognosis of different liver pathological changes in HCV infected patients

Abstract
Background This meta-analysis aimed to assess available evidence on possible associations of interleukin-28B polymorphisms rs8099917 and rs12979860 with development of hepatitis virus-related hepatocellular carcinoma (HCC). Methods PubMed, EMBASE, Google Scholar, and the Chinese National Knowledge Infrastructure databases were systematically searched to identify relevant studies. Meta-analyses were performed to examine the association of interleukin-28B rs8099917 G/T and rs12979860 T/C polymorphisms with development of hepatitis virus-related HCC. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated. Results A total of ten studies involving 2,529 cases and 2,412 controls were included. The G-allele and GT genotype of rs8099917 were significantly associated with increased risk of hepatitis B virus (HBV)-related HCC (allelic model, OR 1.49, 95% CI 1.13–1.96, P=0.005; heterozygous model, OR 1.39, 95% CI 1.04–1.88, P=0.03). Conversely, the TT genotype was found to be significantly associated with lower risk of HBV-related HCC (dominant model, OR 0.68, 95% CI 0.51–0.91, P=0.01). Similar results were observed in the subgroup of Chinese patients and controls. In the pooled data set, the T-allele and TT genotype of rs12979860 showed a significant association with increased HCC risk (allelic model, OR 1.36, 95% CI 1.05–1.78, P=0.02; recessive model, OR 1.75, 95% CI 1.28–2.39, P=0.005; homozygous model, OR 1.99, 95% CI 1.41–2.80, P<0.001). Subgroup analysis based on ethnicity and etiology showed rs12979860 polymorphism to be significantly associated with HCC risk in Caucasians, especially hepatitis C virus-related HCC, according to all five genetic models. In contrast, only the TT genotype of rs12979860 was found to be significantly associated with increased risk of HBV-related HCC, especially in Asians. Conclusion The G-allele of rs8099917 may confer elevated risk of HBV-related HCC, while the wild-type TT genotype may protect against the disease. The T-allele of rs12979860 may increase the risk of HCC, in Caucasians, especially hepatitis C virus-related HCC. The TT genotype of rs12979860 may confer increased risk of HBV-related HCC, especially in Asians. These conclusions should be verified in large, well-designed studies.

Abstract
IFN orchestrates the expression of various genes to halt hepatitis C virus (HCV) replication with the possibility of either reduced or increased liver fibrosis; due to controlled viral replication or overproduction of inflammatory mediators, repectively. In this study, we examined the transcriptional profiling of type I IFN related genes in HCV-chronically infected patients with varying degrees of liver fibrosis. PCR array was used to examine the expression of 84 type I IFN related genes in peripheral blood mononuclear cells (PBMCs) RNA from 12 treatment-naïve chronic HCV patients (5 F0-F1 and 7 F2-F4) and 5 healthy subjects. We further validated our results by quantitative real time PCR (qRT-PCR) in 103 treatment-naïve chronic HCV patients (43 F0-F1 and 60 F2-F4) and 15 controls. PCR array data revealed dysregulation in TLR7 pathway. The expression of TLR7 was decreased by 4 folds and MyD88 was increased by 3 folds in PBMCs of F2-F4 patients when compared to the healthy volunteers (p = 0.03 and 0.002, respectively). In addition, IRF7 and TLR7 showed dramatic downregulation (6 and 8 folds, respectively) in F2-F4 patients when compared to F0-F1 ones. qRT-PCR confirmed the altered expression patterns of TLR7 and MyD88 in F2-F4 patients when compared to either controls or F0-F1 patients. However, by qRT-PCR, IRF7 and NF-κB1 (TLR7 pathway transcription factors) exhibited similar mRNA abundance among F2-F4 and F0-F1 patients. These results suggest that TLR7 and MyD88 are possible candidates as biomarkers for the progression of HCV-induced liver fibrosis and/ or targets for therapeutic intervention.

Abstract
BACKGROUND Nowadays, the immune response to hepatitis C (HCV) treatment has become a crucial issue mostly due to the interleukin 28B (IL-28B) polymorphism effects in chronic HCV patients. The aim of this study was to detect the polymorphism of IL-28B gene (rs12979860) in HCV genotype 1 patients treated with pegylated Interferon and Ribavirin. METHODS From the 2010 to 2012, a total of 115 peripheral blood mononuclear cells (PBMCs) of HCV patients who presented to Gastrointestinal & Liver Disease Research Center (GILDRC), Firoozgar Hospital, Tehran, Iran were enrolled in this retrospective cross sectional study. Samples were then categorized based on the presence of sustained virologic response (SVR and no-SVR). Variables including age, gender, serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels of the two groups were investigated based on different IL-28B genotypes. RESULTS Analysis by the variables of age and gender showed a mean age ± SD of 42.1±14.0 and gender variability of 44 females (38.2%) and 71 males (61.8%). Adding up these results, the analysis of ALT levels revealed that there was between 293 and 14 mg/ml; AST levels ranged between 217 and 17 mg/ml; the viral load (HCV RNA) ranged between 7,822,000 and 50 IU/ml; the prevalence of CC, CT and TT genotypes were 90.9%, 54% and 25.0%. CONCLUSION IL-28B polymorphism has an effective impact on the therapeutic response to ribavirin and peginterferon combination therapy in chronic HCV patients infected by different genotypes. This polymorphism is crucial in natural clearance.

Abstract
Hepatitis C virus (HCV) genotype (GT) 4 represents 12%-15% (15-18 million) of total global HCV infection. It is prevalent in Northern and Equatorial Africa and the Middle East, and is also present in some countries in Europe. GT-4 (and subtype 4a in particular) dominates the HCV epidemic in Egypt. In underdeveloped countries, risk factors associated with HCV infection may be due to unsafe medical practices or other factors such as familial transmission, mother’s HCV status, or illiteracy. HCV prevention and control programs should include health education, increased community awareness towards the disease, controlling infection distribution in health-care centers, proper sterilization of medical and dental instruments, and ensuring safe supply of blood and blood-products. Response rates to a 48-wk combined pegylated-interferon (PEG-IFN) and ribavirin (RBV) treatment range from 40%-69%, and HCV-GT-4 has been considered better than GT-1 but worse than GT-2 and GT-3 in treatment with PEG-IFN/RBV. However, with the introduction of the HCV-GT-1 effective protease inhibitors boceprevir and telaprevir in 2011, HCV-GT-4 became the “most difficult (GT) to treat”. Recently, the direct-acting antivirals (DAAs) with pan- genotypic activities simeprevir, sofosbuvir, and daclatasvir have been recommended in triple regimens with PEG-IFN/RBV for the treatment of HCV-GT-4. An IFN-free regimen will be available for treatment of all genotypes of HCV in the near future. To date, several DAAs have been developed and are currently being evaluated in various combinations in clinical trials. As new regimens and new agents are being approved by the Food and Drug Administration, we can expect the guidelines for HCV treatment to be changed. The availability of shorter, simpler, and more tolerable treatment regimens can reduce the morbidity and mortality associated with HCV infection. With such a large number of therapeutic agents available, we can end up with a range of choices that we can select from to treat patients.

Abstract
BACKGROUND Host genetic factors can affect the progress of hepatitis-C virus (HCV) infection. Interleukin-28B (IL28B) single nucleotide polymorphisms may play an important role in the clearance of HCV spontaneously or with treatment. AIMS The aim of our study was to evaluate the rate of IL28B genotypes in patients with Chronic Hepatitis-C (CHC) and healthy control subjects and to examine the characteristics of patients in each IL28B subgroup. STUDY DESIGN Case-control study. METHODS IL28B polymorphisms were genotyped by Polymerase Chain Reaction and Restriction Fragment Length Polymorphism (PCR-RFLP) in all subjects. RESULTS The mean age was 52.3±10.9 years (33% female) in the CHC patients and 52.5±11.5 years (39.1% female) in the healthy controls. The percentage of patients with a high baseline viral load (≥400,000 IU/mL) was higher in the CT group (69.8%) compared to the C/C (44.4%) and T/T (50%) groups (p=0.021). There was no significant difference in liver fibrosis and liver necroinflammation distribution among the CC, CT and TT genotypes with mild, moderate and severe groups (p=0.058 and p=0.791, respectively). Mean age, gender ratio, body mass index, viral load at baseline, rate of HCV genotypes, baseline ALT levels were not significantly different among the three IL28B subgroups (p>0.05). A significant increase was observed in the frequencies of IL28B rs12979860 TT genotypes in the CHC patients (20.6%) compared to the healthy control group (8.7%) (p=0.033). CONCLUSION In the patients with chronic HCV-genotype 1b and 4 infections, the IL28B rs12979860 (C>T) gene polymorphism frequency of the TT genotype and T allele was higher than in healthy control subjects. This result indicates that the TT genotype may be more effective in the progression of HCV infection than other genotypes.

Abstract
Background Interleukin (IL) 28B single nucleotide polymorphisms may play a role in the clearance of hepatitis C virus (HCV). We aimed to evaluate the treatment response of chronic HCV infection patients to pegile interferon (pegIFN) and ribavirin treatment with regard to IL28B rs12979860 C/T polymorphism. Methods A total of 186 patients (mean age, 55.6 ± 10 years; 65.1% female) who underwent pegIFN and ribavirin treatment for chronic HCV infection were studied. We analyzed demographics, HCV genotype, baseline alanine aminotransferase (ALT) levels, histopathological data, viral load before treatment and at 4, 12, 24, 48, and 72 weeks from the treatment start, and IL28B genotype. IL28B polymorphism was genotyped using polymerase chain reaction based restriction fragment length polymorphism (PCR-RFLP) in all the subjects. Results One hundred forty-five (86.8%) patients were infected with viral genotype 1b, and 13.2% were infected with viral genotype 4. The rates of C/C, C/T, and T/T genotypes were 22.6%, 52.7%, and 24.7% respectively. The percentage of patients with a viral load over 400,000 IU/mL was higher in the C/T group (P = 0.020). Of the patients, 44.6% provided sustained virological response (SVR) to pegIFN and ribavirin combination treatment. The frequency of T allele was 41% in patients with SVR, whereas 59% patients provided no response (P < 0.001). SVR was obtained in 66.7%, 42.9%, and 28.3% of CC, CT, and TT groups (P = 0.001). The rates of rapid virological response (RVR), early virological response (EVR), end-of-treatment response (ETR), and SVR were higher in the CC group than other groups (P = 0.216, P < 0.001, P = 0.001, P = 0.001, respectively). The relapse and null response (NR) rates were higher in TT group and partial response rate (PR) was higher in CT group. Conclusions IL28B rs12979860 C/T gene polymorphism affects the response to antiviral treatment in the patients with chronic HCV genotypes 1b and 4 infections.

Abstract
BACKGROUND About 30% of individuals with hepatitis C virus (HCV) infection are able to clear HCV spontaneously. Differences in host genetics affect the outcome of HCV infection. Single nucleotide polymorphisms (SNPs) of the Interferon lambda (IFNL) genes were associated with spontaneous and treatment-induced clearance of HCV infection. OBJECTIVES The aim of this study was to evaluate the association between the IFNL4 rs12979860 SNP and spontaneous clearance of HCV infection in Iranian population. MATERIALS AND METHODS A case-control study was designed on 91 cases with spontaneous HCV infection clearance and 259 patients with persistent HCV infection as the control group. The rs12979860 SNP was assessed as the most common IFNL polymorphism by PCR-RFLP method. RESULTS Distribution of rs12979860 CC genotype in the spontaneous clearance group was around two folds of its distribution in chronic hepatitis C group (P < 0.001, OR = 4.09, 95% CI = 2.44-6.86). CONCLUSIONS The rs12979860 SNP was observed as a strong host genetic factor associated with spontaneous clearance of hepatitis C infection.

Abstract
Genetic variation of interleukin-28B (IL-28B) rs12979860 T/C polymorphism is associated with the immune response to interferon (IFN) therapy, which is applied in the treatment of chronic viral hepatitis induced by hepatitis B virus (HBV) and hepatitis C virus (HCV). These chronic liver diseases could progress to end-stage liver diseases, such as hepatocellular carcinoma (HCC). The aim of this study was to clarify whether there exists a causal association between IL-28B rs12979860 T/C polymorphism and development of HCC. In a meta-analysis of six studies with 850 cases and 811 controls, we summarized the data on the association between IL-28B rs12979860 T/C polymorphism and HCC risk and calculated ORs and 95 % CIs to estimate the association strength. We observed that IL-28B rs12979860 T/C polymorphism was positively associated with overall HCC risk (TT vs. CC: OR = 2.38; 95 %, 1.60-3.55; TT vs CT + CC: OR = 1.79; 95 %, 1.23-2.60). In the stratified analysis by ethnicity, the robust association retained in Caucasians with higher risk among TT carriers relative to the CC carriers. A similar trend was found in the studies of healthy controls when data were stratified by source of controls. The combined data suggest that IL-28B rs12979860 T/C polymorphism seems to augment the risk of developing HCC, especially in Caucasians.

Abstract
BACKGROUND The role of interleukin 28B (IL-28B) polymorphisms played in hepatitis C virus (HCV) infection has been gradually explicit, especially in HCV genotype 1, 2 and 3. However, no confirmative conclusion was acquired in genotype 4 HCV patients. Thus we conducted this meta-analysis. METHODS We searched the commonly used databases both in English and Chinese. Meta-analysis was performed in fixed/random effects models using STATA 12.0 or R software. Publication bias was examined through Egger's test and Begg's funnel plot. RESULTS In total, 11 studies were included in this meta-analysis, encompassing 1284 patients who were mono-infected with HCV-4 and received Peg-interferon (Peg-IFN) plus Ribavirin (Rbv). Around 53.0% patients would achieve sustained virologic response (SVR), 36.6% achieve rapid virologic response (RVR) and 62.4% achieve end of treatment response (ETR). Egyptian patients had a higher rate achieving SVR than non-Egyptian patients (56.3% vs. 47.8%). IL-28B rs12979860 CC genotype not only favored SVR (OR = 3.95, 95%CI = 3.03-5.16), regardless of citizenship, but also favored RVR (OR = 3.82, 95%CI = 2.46-5.95) and ETR (OR = 4.22, 95%CI = 2.81-6.34). IL-28B rs8099917 genotype TT also correlated with SVR (OR = 3.41, 95%CI = 1.92-6.07), but might not with RVR. IL-28B rs12980275 might still correlate with SVR, but warrant more studies to validate. CONCLUSIONS The favorable IL-28B rs12979860 genotype is a statistically significant predictor of SVR, RVR and ETR in HCV-4 monoinfected patients treated with Peg-IFN plus Rbv. Rs8099917 might predict SVR but not RVR. Egyptian HCV-4 patients would achieve better outcomes than non-Egyptian patients when treated with standard care.

Abstract
BACKGROUND Recent genome wide association studies (GWAS) have shown important roles of single nucleotide polymorphisms (SNP) near region of interleukin B 28 (IL28B) gene in spontaneous and drug-induced clearance of hepatitis C virus (HCV) in genotype 1 HCV infection. OBJECTIVES This meta-analysis was designed to determine the world-wide distribution patterns of IL28B genotypes and alleles, and to find possible linkages between IL28B and HCV genotypes. PATIENTS AND METHODS Manual and electronic databases were searched. Critical appraisal was performed. According to the results of heterogeneity tests, we used fix/random model for the analysis. The data concerning patients' ethnicity and HCV genotypes were analyzed by using statistical analysis software. RESULTS A total of 255 articles were found. After article review and quality assessment, 50 studies, including 18662 patients and 1313 healthy subjects, were analyzed. Presence of HCV genotype 3 versus genotype 1 was significantly associated with a higher frequency of CC genotype and C allele, with an odds ratio (OR) of 1.68 (95% CI: 1.44-1.99) and 1.49 (95% CI: 1.33-1.67), respectively. Prevalence of the rs12979860 CC genotype among genotype 1 HCV infected patients of Asian ethnicity was 69.48% (95% CI: 65.20-73.77), which was significantly higher than its prevalence [33.27% (95% CI: 28.88-37.67)] in the Caucasian genotype 1 HCV infected patients. Prevalence of rs12979860 TT genotype in the African-American genotype 1 HCV infected patients was the highest [36.20% (95% CI: 32.91-39.49)], and significantly different compared to all other ethnicities. CONCLUSIONS There were significant linkages between HCV genotypes and IL28B genotypes/alleles. Patients with a favorable IL28B and genotypes 1 and 4 HCV infection stand a better chance to clear HCV in the acute phase.

Abstract
HCV recurrence represents a universal phenomenon after liver transplantation. In this study Fifty HCV patients who underwent living donor liver transplantation were enrolled and factors that may accelerate HCV reinfection of the allograft such as donor's age and degree of liver steatosis, recipient's age, gender, BMI, MELD score, liver functions, HCV viral load, type of immunosuppressive drug, and genetic polymorphisms of IL28B, OAS, and IL1B were studied. The results of disease-free survival (DFS) rates showed inverse correlation with the recipient's postoperative levels of ALT, AST, ALP (P < 0.001, <0.001, and 0.006 resp.) as well as pre- and postoperative titers of HCV RNA (P < 0.003 and <0.001 resp.). Recipient's IL28B SNP was a significant factor in predicting postoperative DFS (P < 0.025). However, SNPs in OAS and IL1B genes had no apparent correlation with DFS. Cox proportional hazards model revealed that patients with elevated levels of ALT, preoperative viral titers, IL28B CT, and IL28B TT were 8.28, 4.22, 3.35, and 1.36 times, respectively, more likely to develop recurrence. In conclusion IL28B SNP, ALT level, and preoperative HCV titer besides proper choice of immunosuppressant are helpful for predicting posttransplant HCV recurrence and DFS.

Abstract
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.

Abstract
BACKGROUND The current stopping rule for peginterferon/ribavirin therapy in hepatitis C virus genotype-1 (HCV-1) patients is based on an early virological response (EVR, defined as >2 log(10) viral reduction at treatment week 12). We aimed to explore rapid stopping rules at week 4. METHODS We randomly allocated 528 HCV-1 patients into training and validation sets (at a 1∶2 ratio). The interleukin-28B rs8099917 genotypes and on-treatment virological responses were evaluated to determine the negative predictive value (NPV) for achieving a sustained virological response (SVR, defined as undetectable HCV RNA 24 weeks after end-of-treatment). The study was approved by the ethics committees of the participating hospitals. All of the patients gave written informed consent before enrollment. RESULTS A poor week 4 response (W4R), defined as a HCV RNA reduction of <1 log(10) IU/mL at week 4 or a week 4 HCV RNA>10,000 IU/mL with interleukin-28B non-TT genotype, had the highest NPV (95%). In the complete sample, poor W4R could identify 43.4% (59/136) of the non-responders, with an NPV of 95% and a false negative rate of only 0.8% (3/396). The multivariate analysis revealed that a poor W4R was the most important negative predictor (odds ratio/95% confidence intervals: 49.01/13.70-175.37), followed by the lack of an EVR. In addition to HCV RNA<1 log(10) IU/mL reduction, using the criteria of HCV RNA>10,000 IU/mL/non-TT genotype helped identifying an additional one-third of non-SVR patients at W4.Using the strategy of sequential rapid stopping rule strategy could identify 53.7% (73/136) of the non-responders (43.4% at week 4 and an addition 11.3% at week 12), as compared to 40.4% for the classical week-12 early stopping rule. CONCLUSIONS Sequential rapid stopping rules using on-treatment virological responses and interleukin-28B genotype can rapidly identify additional peginterferon/ribavirin non-responders.
