Abstract
The tripartite motif (TRIM)-5 and TRIM22 are involved in innate immune response and show anti-viral activities. The current study aimed at evaluating the association of TRIM5 and TRIM22 polymorphisms with treatment outcomes in patients with chronic hepatitis C virus (CHC). TRIM5 rs3824949 and TRIM22 polymorphisms (rs7113258, rs7935564, and rs1063303) were genotyped using TaqMan polymerase chain reaction (PCR) assay in 425 treatment-naïve CHC patients. Rapid virological response (RVR), early virological response (EVR), and sustained virological response (SVR) were found in 54.1%, 74.8%, and 67.1% of the patients, respectively. RVR and SVR were associated with TRIM5 rs3824949 (GG), TRIM22 rs1063303 (GC), and TRIM22 rs7113258 (AA), while there was a relationship between TRIM5 rs3824949 (GG) and EVR. TRIM5 and TRIM22 single nucleotide polymorphisms (SNPs) were strongly associated with increased odds of RVR, EVR, and SVR after an interferon-based therapy in patients with CHC.

Abstract
Single nucleotide polymorphisms (SNPs) near the interleukin-28B (IL28B), interferon lambda 4 (IFNL4) and the human leukocyte antigen (HLA) gene are associated with treatment responses in patients with chronic hepatitis C (CHC) virus infection treated with pegylated interferon-α and ribavirin (pegIFN-α/RBV). We compared the role of IL28B SNPs (rs12979860, rs12980275, and rs8099917), IFNL4 ss469415590 and HLA rs4273729 with treatment outcomes in patients with CHC virus. A total of 520 Iranian patients with CHC infection were enrolled. SNPs in IL28B, IFNL4 ss469415590 and HLA rs4273729 were genotyped by PCR-restriction fragment length polymorphism, TaqMan® Real-Time PCR and direct sequence. Out of 520 CHC treatment-naive patients, 42.9% were infected with HCV-1a, 15.4% with HCV-1b, 9.8% with HCV-2, and 31.9% with HCV-3a. Rapid virologic response (RVR), complete early virologic response (cEVR), and sustained virologic response (SVR) were 53.3%, 73.8%, and 66.7%, respectively. Multivariate logistic regression analysis showed that IL28B rs12980275 and IFNL4 ss469415590 in all HCV genotypes were associated with RVR. In addition, IL28B rs12979860 and RVR in all HCV genotypes and IL28B rs12980275, IFNL4 ss469415590, and HLA rs4273729 in HCV subtypes 1a, 1b, and 3a correlated with cEVR. In patient's achieving-SVR, IL28B rs12980275, and RVR in all HCV genotypes and IL28B rs12979860, IFNL4 ss469415590, and HLA rs4273729 in HCV subtypes 1a, 1b, and 3a were the powerful predictor factors. As the first report of its kind published in Iran, we indicated that beside IL28B SNPs and HLA rs4273729, IFNL4 ss469415590 was a powerful predictor factor for RVR, cEVR and SVR. Genotyping these SNPs may be a helpful priority in the treatment of patients with HCV infection, especially in countries where access to triple or double therapy with a viral protease inhibitor is limited.

Abstract
The scavenger receptor type B class I (SCARBI) is known to be involved in the entry of hepatitis C virus (HCV) into the host, while interleukin-15 (IL15) is an important cytokine in both the innate and acquired immune responses against HCV infection. We investigated the association of IL15 rs10833 or SCARB1 rs10846744 polymorphisms with treatment responses in patients with chronic HCV (CHC). SCARB1 rs10846744 and IL15 rs10833 were identified in 365 treatment-naïve CHC patients through genotyping by TaqMan® Real-Time PCR and PCR-restriction fragment length polymorphism (RFLP), respectively. Of these 365 CHC treatment-naïve patients, rapid virological response (RVR), complete early virological response (cEVR), and sustained virological response (SVR) were observed in 53.2%, 76.4%, and 66.0% of the patients, respectively. Multivariate logistic regression analysis revealed that RVR was associated with sex (P=0.016), aspartate aminotransferase (AST) (P=0.026), IL15 rs10833 (AA) genotype (P<0.001), and SCARB1 rs10846744 (CC) genotype (P<0.001), while there was a relationship between alanine aminotransferase (ALT) (P=0.013) and IL15 rs10833 (AA) genotype (P<0.001) with cEVR. Age (<40years) (P=0.001), AST (P=0.029), ALP (P=0.028), HCV genotypes (P=0.005), HCV viral load (P=0.026), IL15 rs10833 (AA) genotype (P<0.001), and SCARB1 rs10846744 (CC) genotype (P=0.001) were strongly associated with SVR. In conclusion, the SCARB1 rs10846744 (CC) and IL15 rs10833 (AA) genotypes can be considered as powerful predictors of treatment responses in CHC patients treated with an interferon-based therapy.

Abstract
AIM Telaprevir (TVR) remarkably improves the efficacy of interferon treatment for chronic hepatitis C. Interleukin-28B (IL28B) genotype and interferon-gamma-inducible protein-10 (IP-10) level predict virologic response to peg-interferon (Peg-IFN)/ribavirin (RBV) therapy. We aimed to investigate the usefulness of pretreatment serum IP-10 levels and IL28B genotyping in predicting sustained virologic response (SVR) to TVR-based triple therapy. METHODS In this multi-center study, patients infected with hepatitis C virus genotype 1 with high viral load (⩾5.0logIU/mL) were treated with TVR for 12weeks and Peg-IFN/RBV for 24weeks in Japan. IL28B genotype, serum IP-10 levels, other clinical parameters, and drug dosages were assessed before treatment. RESULTS We included 121 patients who were treated with TVR for at least 8weeks and Peg-IFN/RBV for 24weeks. The median IP-10 levels were significantly lower in rapid virologic response (RVR) or SVR in the IL28B non-TT genotype group, with no significant difference in the TT genotype group. RVR rates were significantly lower in the group with higher serum IP-10 levels (>450pg/mL). In the non-TT IL28B genotype group, RVR and SVR rates were significantly lower in the group with higher IP-10 levels. SVR rates in the group with lower IP-10 levels (<450pg/mL) increased to 82% for those showing RVR, but reduced to 27% in the group with higher IP-10 levels for those not showing RVR. CONCLUSIONS Determination of serum IP-10 levels before treatment could be useful for predicting favorable virologic response to TVR-based triple therapy, especially in patients with IL28B non-TT genotype.

Abstract
AIM To investigate peg-interferon (peg-IFN) and ribavirin (RBV) therapy in Myanmar and to predict sustained virologic response (SVR). METHODS This single-center, open-label, study was conducted in Myanmar between 2009 and 2014. A total of 288 patients infected with HCV genotypes 1, 2, 3 and 6 were treated with peg-IFN alpha-2a (180 μg/wk) or alpha-2b (50 to 100 μg as a weight-based dose) and RBV as a weight-based dose (15 mg/kg/d). Treatment duration was 48 wk for genotypes 1 and 6, 24 wk for genotype 2, and 24 or 48 wk for genotype 3 based on rapid virologic response (RVR). Those co-infected with hepatitis B received 48 wk of therapy. RESULTS Overall, SVR was achieved for 82% of patients and the therapy was well tolerated. All patients achieved SVR at equivalent rates regardless of HCV genotype (P = 0.314). Low fibrosis scores (P < 0.001), high baseline albumin levels (P = 0.028) and low baseline viral loads (P = 0.029) all independently predicted SVR. On the other hand, IL-28B TT and CC genotypes were not found to significantly predict SVR (P = 0.634; P = 0.618). Among those who completed treatment, the occurrence of RVR showed a > 96% positive predictive value for achieving SVR. Treatment duration did not significantly impact the likelihood of achieving SVR for patients infected with genotype 3 HCV (P = 0.371). The most common adverse events were fatigue (71%) and poor appetite (60%). Among patients with genotype 3 HCV, more patients in the 48-wk treatment group required erythropoietin than in the 24-wk treatment group (61.1% vs 49.2%). CONCLUSION SVR rates were high with peg-IFN and RBV therapy in Myanmar. Fibrosis scores, baseline albumin, HCV RNA levels and RVR independently predicted SVR.

Abstract
AIM To evaluate interferon-λ3 (IFNL3) polymorphisms in response-guided pegylated interferon-α plus ribavirin (Peg-IFNα/RBV) therapy for genotype 2 (G2) chronic hepatitis C. METHODS Between January 2006 and June 2012, a total of 180 patients with chronic infections of G2 hepatitis C virus (HCV) were treated with response-guided Peg-IFNα/RBV therapy. The treatment duration was 24 wk for patients who achieved rapid virologic response (RVR), and 36 or 48 wk for patients who did not. Then, the impact of the IFNL3 single nucleotide polymorphism genotype (TT/non-TT at rs8099917) on treatment outcomes was evaluated in the 180 patients, and between patients infected with either HCV sub-genotype 2a or 2b. RESULTS Of the 180 patients evaluated, 111 achieved RVR, while the remaining 69 patients did not. In RVR patients, the sustained virologic response (SVR) rate was 96.4%, and the IFNL3 genotype did not influence the SVR rate (96.6% vs 95.8% in IFNL3 genotype TT vs non-TT). However, in non-RVR patients, the SVR rate decreased to 72.5% (P < 0.0001), and this rate was significantly different between the IFNL3 genotype TT and non-TT groups (80.0% vs 42.9%, P = 0.0146). Multivariate regression analysis in non-RVR patients identified the IFNL3 genotype TT as the only baseline-significant factor associated with SVR (OR = 5.39, 95%CI: 1.29-22.62; P = 0.0189). In analysis according to HCV sub-genotype, no significant difference in the SVR rate was found between HCV sub-genotypes 2a and 2b. CONCLUSION In response-guided Peg-IFNα/RBV combination therapy for chronically HCV G2-infected patients, the impact of the IFNL3 genotype on SVR was limited to non-RVR patients.
