AIM: To investigate the impact of IL28B and OAS gene polymorphisms on interferon treatment responses in children with chronic hepatitis B. METHODS: We enrolled 52 children (between the ages of 4 and 18) with hepatitis B e antigen-negative chronic hepatitis B (CHB), who were treated with pegylated interferon alfa for 48 wk. Single nucleotide polymorphisms in the OAS1 (rs1131476), OAS2 (rs1293747), OAS3 (rs2072136), OASL (rs10849829) and IL28B (rs12979860, rs12980275 and rs8099917) genes were studied to examine their associations with responses to IFN treatment in paediatric patients...

BACKGROUND AND AIMS: Early post-transplant hepatic fibrosis is associated with poor outcomes and may be influenced by donor/recipient genetic factors. The rs368234815 IFNL4 polymorphism is related to the previously described IL28B polymorphism, which predicts etiology-independent hepatic fibrosis. The aim of this study was to identify the impact of donor and/or recipient IFNL4 genotype on early fibrosis among patients transplanted for hepatitis C (HCV). METHODS: Clinical data were collected for 302 consecutive patients transplanted for HCV...

BACKGROUND: Several genes and their single nucleotide polymorphisms (SNPs) are associated with either spontaneous resolution of hepatitis C infection or better treatment-induced viral clearance. We tested a cohort of intravenous drug users (IVDU) diagnosed with chronic hepatitis C virus (HCV) for treatment response and its association with the SNPs in the interleukin-6 (rs1800795-IL6) and the interleukin-28B (rs12979860-IL28B) genes. METHODS: The study included 110 Croatian IVDU positive for anti-HCV antibody...

We assessed implementation of precision medicine within the Veterans Health Administration. We analyzed the use of interleukin-28B (IL28B) pharmacogenetic test, which predicts interferon-α treatment response in patients with hepatitis C. Patients with favorable CC genotype exhibit a two-fold higher response than patients with less favorable genotypes (CT and TT). Linking IL28B tests to Veterans Health Administration clinical data, we analyzed test use, concordance with guidelines, subsequent interferon-α treatment, and site variations...

:  Background. Patient race and ethnicity have historically impacted HCV treatment response. This phase 3 study evaluated daclatasvir with peginterferon-alfa-2a/ribavirin (pegIFN alfa-2a/RBV) in treatment-naive black/African American (AA), Latino, and white non-Latino patients with chronic HCV genotype 1 infection. MATERIAL AND METHODS: In this single-arm, open-label study, 246 patients received daclatasvir plus pegIFN alfa-2a and weight-based RBV. Patients with an extended rapid virologic response (eRVR; undetectable HCV-RNA at treatment weeks 4 and 12) received 24 weeks of treatment; those without eRVR received an additional 24 weeks of treatment with pegIFN alfa-2a/RBV...

Hepatitis C virus (HCV) is the leading cause of liver fibrosis and hepatocellular carcinoma (HCC). At present, there is no predictive biomarker for the patients at high risk of developing HCC. In this study, we examined the association between single-nucleotide polymorphisms (SNPs) in 3 innate immunity genes [2'-5'oligoadenylate synthetase 1 (OAS1) rs10774671, interleukin 28B (IL28B) rs12979860, and low molecular mass polypeptide 7 (LMP-7) at codon 49] besides cytomegalovirus (CMV) coinfection and susceptibility to HCC in genotype 4 (GT4) chronically infected Egyptian patients...

Following interferon-based therapy for chronic hepatitis C, the negativity of hepatitis C virus RNA is essential to achieve viral clearance at the end of treatment. We report a case of clearance of chronic hepatitis C virus infection following early discontinuation (at 6 weeks) of peginterferon plus ribavirin therapy, without negativity for hepatitis C virus RNA during the treatment period. The patient was a 76-year-old Japanese male infected with hepatitis C virus genotype 1b and TT of IL28B rs8099917. Hepatitis C virus RNA remained positive at persistently low levels for more than 2 months after the cessation of therapy and became negative at 7 months after the discontinuation of therapy...

Single-nucleotide polymorphisms (SNPs) in the Interleukin-28B (IL28B) gene and rs4273729 in the human leukocyte antigen (HLA) gene in chronic hepatitis C (CHC) virus infection are important for predicting treatment outcome. In this study, the distribution of IL28B SNPs (rs12979860 and rs12980275) and HLA rs4273729 in rapid virologic response (RVR), complete early virologic response (cEVR) and sustained virologic response (SVR) in HCV Iranian patients with CHC virus infection was assessed. IL28B genotyping and rs4273729 were performed using the amplification refractory mutation system (ARMS)-PCR and direct sequencing in 190 CHC virus infections, respectively...

Type 2 Diabetes (T2D) develops, when ß-cell insulin response fails to compensate for insulin resistance. Recent studies reported associations between the IL28B polymorphisms (rs12979860 and rs8099917) and T2D development in hepatitis C virus (HCV) patients. To identify possible association with T2D independent from virus infection, we investigated both IL28B polymorphisms in T2D patients and healthy controls (HC). No association was found comparing the genotype and allele frequencies of both IL28B polymorphisms between T2D patients and HC...

: Hepatitis C virus (HCV) is unique among RNA viruses in its ability to establish chronic infection in the majority of exposed adults. HCV persists in the liver despite interferon (IFN)-stimulated gene (ISG) induction; robust induction actually predicts treatment failure and viral persistence. It is unclear which forms of HCV RNA are associated with ISG induction and IFN resistance during natural infections. To thoroughly delineate HCV RNA populations, we developed conditions that fully separate the strands of long double-stranded RNA (dsRNA) and allow the released RNAs to be quantified in reverse transcription/polymerase chain reaction assays...

REVIEW

Hepatitis C virus (HCV) is a major cause of chronic viral hepatitis that can lead to cirrhosis and hepatocellular carcinoma. Only a minority of patients can clear the virus spontaneously. Elimination of HCV during acute infection correlates with a rapid induction of innate, especially interferon (IFN)-induced genes, and a delayed induction of adaptive immune responses. There is a strong association between genetic variants in the IFNλ (IL28B) locus with the rate of spontaneous clearance. Individuals with the ancestral IFNλ4 allele capable of producing a fully active IFNλ4 are paradoxically not able to clear HCV in the acute phase and develop chronic hepatitis C (CHC) with more than 90% probability...

Hashimoto's thyroiditis (HT) is thought to result from decreased T helper type 2 (Th2) responses, leading to the progressive destruction of thyrocytes. IFN-λ1, -λ2, and -λ3 (also known as IL-29, IL-28A, and IL-28B, respectively) are recently described members of the IFN-λ family and have been shown to decrease the production of Th2 cytokines in vitro. However, the role and mechanism of IFN-λ1 in HT remain unknown. The purpose of this study was to examine whether IL29 and IL28B gene polymorphisms are susceptibility genes for the development of HT...

Type III interferons (IFNs) or IFN-λs (IFN-λ1/IL29, IFN-λ2/interleukin (IL)-28A and IFN-λ3/IL-28B) consist of a recently identified group of IFNs, implicated initially in several human diseases, including cancer and autoimmunity. In this study, we sought to investigate the expression of type III IFNs and their common receptor IFN-λR1/IL-28Ra in Sjögren's syndrome (SS). Type III IFN expression was examined in minor salivary gland tissues (MSG), peripheral blood mononuclear cells (PBMCs), sera and resting or Toll-like receptor (TLR)-stimulated salivary gland epithelial cells (SGEC) from SS patients and sicca-complaining controls...

Maternal innate and adaptive immune responses are modulated during pregnancy to concurrently defend against infection and tolerate the semiallogeneic fetus. The restoration of these systems after childbirth is poorly understood. We reasoned that enhanced innate immune activation may extend beyond gestation while adaptive immunity recovers. To test this hypothesis, the transcriptional profiles of total peripheral blood mononuclear cells following delivery in healthy women were compared with those of nonpregnant control subjects...

BACKGROUND & AIMS: Daclatasvir plus asunaprevir (DCV + ASV) has demonstrated potent antiviral activity in patients with hepatitis C virus (HCV) genotype 1b infection. A definite conclusion about efficacy and safety of DCV + ASV in patients with HCV genotype 1b is not available. A meta-analysis was conducted to evaluate outcomes of all-oral treatment with DCV + ASV in terms of sustained virological response at 12 (SVR12 ) , 24 (SVR24 ) weeks and adverse effects (AEs) after the end of treatment...
