Abstract
Abstract
Background
Hepatitis C virus is a viral infection associated with autoimmune disorders. This virus has hepatic and extrahepatic manifestations. One of the extrahepatic manifestations associated with the hepatitis C virus includes oral lichen planus. Oral lichen planus is an autoimmune disorder mainly affecting the tongue and buccal mucosa. It clinically represents grayish-white striae bilaterally on the buccal mucosa. The pathogenesis involves the progression of the hepatitis C virus, and oral lichen planus affects T lymphocytes. Specific proteins and cytokines activate these T lymphocytes, which act as biomarkers to detect certain diseases. Interleukin 10 is an anti-inflammatory cytokine, whereas interleukin 17 is a pro-inflammatory cytokine. These cytokines have a pathophysiological role and act as biomarkers for many diseases. Therefore, this review article aims to establish the role of interleukin 10 and interleukin 17 as biomarkers for hepatitis C-associated oral lichen planus.
Conclusion
Hepatitis C virus is an infectious disease that can lead to liver cirrhosis, and oral lichen planus is a premalignant lesion that can lead to oral carcinoma. As interleukin 10 lessens the immune pathologies and interleukin 17 mediates proinflammatory response, therefore, these biomarkers have a role in progression of these diseases.

Ali HN, Niranji SS, Al‐Jaf SMA. Association of tumor necrosis factor alpha ‐308 single nucleotide polymorphism with SARS CoV‐2 infection in an Iraqi Kurdish population. J Clin Lab Anal 2022; 36:e24400. [PMID: 35373411 PMCID: PMC9102518 DOI: 10.1002/jcla.24400] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2022] [Revised: 03/21/2022] [Accepted: 03/22/2022] [Indexed: 12/26/2022] Open
Abstract
Uncovering risk factors playing roles in the severity of Coronavirus disease 2019 (Covid‐19) are important for understanding pathoimmunology of the disease caused by severe acute respiratory syndrome Coronavirus 2 (SARS CoV‐2). Genetic variations in innate immune genes have been found to be associated with Covid‐19 infections. A single‐nucleotide polymorphism (SNP) in a promoter region of tumor necrosis factor alpha (TNF‐α) gene, TNF‐α −308G>A, increases expression of TNF‐α protein against infectious diseases leading to immune dysregulations and organ damage. This study aims to discover associations between TNF‐α −308G>A SNP and Covid‐19 infection. Polymerase chain reaction‐restriction fragment length polymorphism (PCR‐RFLP) was used for genotyping a general Kurdish population and Covid‐19 patients. The homozygous mutant (AA) genotype was found to be rare in the current studied population. Interestingly, the heterozygous (GA) genotype was significantly (p value = 0.0342) higher in the Covid‐19 patients than the general population. This suggests that TNF‐α −308G>A SNP might be associated with Covid‐19 infections. Further studies with larger sample sizes focusing on different ethnic populations are recommended.

Abstract
Background Genetic changes may induce dysregulated cytokine production and affect the progression of the chronic disease caused by the hepacivirus C (HCV) because the balance of pro- and anti-inflammatory cytokines determines the outcome of infection. This study evaluated the TNFA -308G>A and IL10 -1082A>G polymorphisms in the susceptibility and progress of chronic hepatitis C. Method The study included 101 samples from patients with chronic hepatitis C and 300 samples from healthy donors. Polymorphisms were typed by real-time PCR and were analyzed for associations with histopathological parameters (according to METAVIR classification) and HCV viral load. Results The polymorphic genotype for the TNFA -308G>A variant was not present in the group of patients with chronic hepatitis C and its absence could be associated with protection against HCV infection (p = 0.0477). Patients with the polymorphic genotype of the IL10 -1082A>G polymorphism had higher HCV viral load than wild-type patients (p = 0.0428). Neither polymorphism was associated with different levels of necroinflammatory activity or fibrosis scores. Conclusion Our results suggest the polymorphic genotype at TNFA -308G>A as protective against chronic HCV infection, and the polymorphic genotype at the IL10 -1082A>G variant associated with higher HCV viral load. Further studies must be performed in order to confirm these associations.

Abstract
Cytokines play an important role in modulating inflammation during viral infection, including hepatitis C virus (HCV) infection. Genetic polymorphisms of cytokines can alter the immune response against this infection. The objective of this study was to investigate the possible association between chronic hepatitis C virus infection susceptibility and cytokine gene polymorphism for interleukin-10 (IL-10) rs1800896 and rs1800871, interleukin 6 (IL-6) rs1800795, TNF-α rs1800629, and TGF-β1 rs1800471 in Malay male drug abusers. The study was conducted on 76 HCV-positive (HP) male drug abusers and 40 controls (HCV-negative male drug abusers). We found that there were significant differences in the frequencies of genotype for IL-10 rs1800871 (p = 0.0386) and at the allelic level for IL-10 rs1800896 A versus G allele (p = 0.0142) between the HP group and the control group. However, there were no significant differences in gene polymorphism in interleukin 6 rs1800795, TNF-α rs1800629 and TGF-β1 rs1800471. These findings suggest significant associations between gene polymorphism for IL-10 rs1800871, IL-10 rs1800896 (at the allelic level) and susceptibility to HCV infection among Malay male drug abusers.

Abstract
OBJECTIVE To identify specific Chinese medicines (CM) that may benefit patients with primary liver cancer (PLC), and to explore the mechanism of action of these medicines. METHODS In this retrospective, singlecenter study, prescription information from PLC patients was used in combination with Traditional Chinese Medicine Inheritance Supports System to identify the specific core drugs. A system pharmacology approach was employed to explore the mechanism of action of these medicines. RESULTS Taking CM more than 6 months was significantly associated with improved survival outcomes. In total, 77 putative targets and 116 bioactive ingredients of the core drugs were identified and included in the analysis (P<0.05). A total of 1,036 gene ontology terms were found to be enriched in PLC. A total of 75 pathways identified from Kyoto Encyclopedia of Genes and Genomes were also enriched in this disease, including fluid shear stress, interleukin-17 signaling, signaling between advanced glycan end products and their receptors, cellular senescence, tumor necrosis factor signaling, p53 signaling, cell cycle signaling, steroid hormone biosynthesis, T-helper 17 cell differentiation, and metabolism of xenobiotics by cytochrome. Docking studies suggested that the ingredients in the core drugs exert therapeutic effects in PLC by modulating c-Jun and interleukin-6. CONCLUSIONS Receiving CM for 6 months or more improves survival for the patients with PLC. The core drugs that really benefit for PLC patients likely regulates the tumor microenvironment and tumor itself.

Abstract
Cytokines are extensively involved in the process of hepatitis C virus (HCV) infection and take a crucial part in host immune regulation. We aimed to explore the potential correlation of cytokine single nucleotide polymorphisms (SNPs) with HCV susceptibility and response rate of interferon (IFN)-based antiviral therapy in Chinese Han population.A case-control genetic association study was conducted between 198 patients with chronic HCV genotype 1b infection and 142 healthy controls. Genetic polymorphisms of TNF-α (rs1800629), TGF-β (rs1800469), IL-10 (rs1800896, rs1800871, and rs1800872), IL-6 (rs1800795, rs1800796), IFN-γ (rs2430561), and IL-28B (rs12979860, rs12980275, and rs8099917) were analyzed by MassARRAY SNP technology. Patients were treated with IFNα-2b or pegylated-IFNα-2a plus ribavirin for 48 weeks. Sustained virological response (SVR) was assessed 6 months after the completion of the treatment.The IL-28B rs12979860-CC (odds ratio [OR] = 4.35, 95% confidence interval [CI]: 1.69-11.21, P = .001), rs12980275-AA (OR = 3.41, 95% CI: 1.08-10.76, P = .028), and rs8099917-TT (OR = 3.86, 95% CI: 1.49-10.12, P = .004) were significantly associated with SVR, and IL-10 rs1800871-TT (OR = .50, 95% CI: 0.25-1.00, P = .049) and rs1800872-AA (OR = .50, 95% CI: 0.25-1.00, P = .049) were also significant for SVR. No association was found between the cytokine SNPs and HCV susceptibility. Additionally, multivariate analysis showed that low baseline viral load (OR = 3.63, 95% CI: 1.01-13.02, P = .048), pegylated-IFN (OR = 9.68, 95% CI: 1.14-82.13, P = .037) and rs12979860-CC (OR = 6.08, 95% CI: 2.00-18.46, P = .001) were independent factors for SVR.IL-28 and IL-10 gene polymorphisms played an important role in predicting host response to IFN-based antiviral therapy in HCV genotype 1b infection.

Abstract
Genotype 1 of hepatitis C virus (HCV) is the most prevalent worldwide. Pegylated-interferon and ribavirin therapy is still used in the developing world but has less efficiency in this genotype. Single nucleotide polymorphisms (SNPs) rs12979860 and rs8099917 (IL28B) and rs1800896, rs1800871, and rs1800872 (IL10) are related to treatment outcome, but previous studies clustered nonresponse and relapse patients. The aim of this study is to analyze the frequency of those SNPs in HCV genotype 1 for response, nonresponse, or relapse. Patients were classified according to treatment outcome. Genomic DNA was extracted by blood samples and SNPs were defined by PCR and sequencing. Data analysis was performed with R project. The frequency of rs12979860 CC was similar among responders (0.48) and relapsers (0.46) and lower among nonresponders (0.18). The same trend was observed for rs8099917 TT. rs12979860 CC showed a protective effect for relapsers compared to nonresponders (OR = 0.25) as it occurs with responders (OR = 0.17). Haplotypes 12979860/C rs8099917/T were associated with protection against the nonresponder phenotype compared to responders (OR = 0.27) or relapsers (OR = 0.37). Frequency of rs12979860 and rs8099917 is different between relapsers and nonresponders, but similar between relapsers and responders.

Abstract
OBJECTIVES Interleukin-10 (IL-10) plays an important role in the immunity to hepatitis C virus (HCV). Insofar as IL-10 variants are associated with altered levels of IL-10, previous studies that examined the association of IL-10 polymorphisms with the susceptibility to and progression of chronic HCV, and response to anti-viral treatment were inconsistent. We investigated the association between common IL-10 variants in the intron and the promotor region with HCV and associated features. METHODS Study subjects comprised 120 patients infected with HCV-1b, and treated with Peg-IFN/RBV. Genotyping of six IL-10 promoter variants in the intron region (rs1878672, rs1554286, rs1518111) and promotor region (rs1800872, rs1800871, rs1800896) were done by real-time PCR. RESULTS Compared to G/G, carriage of IL-10 rs1800896 (-1082A/G) A/A genotype was more frequent in patients with sustained virological response (SVR). The decline in viral load over the first 12weeks of treatment was more pronounced in rs1800896 A/A genotype carriers, compared to G/G genotype carriers, and was irrespective of the treatment dosage. Carriage of rs1800896 A/A genotype was positively associated with improvement in viral load decline, which was simultaneous, with and without carriage of the common favourable IL-28B variant. Carriage of both IL-10 rs1800896 G/G and IL-28B non-favourable genotype was associated with twice the risk of getting slow decline of viral load during treatment. Haploview analysis identified ACGCTA and CCGCTG haplotypes to be linked with excellent PegIFN/RBV cure rate, and complete HCV eradication. On the other hand, ACGCTG and CCGCTA haplotypes were associated with resistance to PegIFN/RBV treatment. CONCLUSION IL-10 rs1800896 variant markedly influences the clinical outcome of HCV infection, and is a determinant of the response to HCV treatment.

Abstract
Tumor necrosis factor-alpha (TNFα) and transforming growth factor-beta (TGFβ1) cytokines are highly implicated in liver fibrosis. Polymorphisms in these cytokines affect their expression, secretion, and activity. This study aimed to evaluate the influence of TNFα -308 G/A and TGFβ1 -509 C/T polymorphism on hepatic fibrosis progression in Egyptian patients with hepatitis C virus (HCV) genotype 4. Genotyping of TNFα -308 G/A and TGFβ1 -509 C/T was performed using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis in 122 subjects (50 healthy controls and 72 HCV patients). Also, serum TNFα and TGFβ1 levels were detected by enzyme-linked immunosorbent assay (ELISA). The genotyping results of early (F0-F1, n = 36) and late (F2-F4, n = 36) HCV fibrosis patients showed that late fibrosis patients had higher TNFα -308 AA genotype and TGFβ1 -509 TT genotype than early fibrosis patients (p = 0.016, 0.028, respectively). Moreover, the TNFα and TGFβ1 serum levels were significantly higher in HCV patients with TNFα A containing genotypes (GA+AA) (p = 0.004) and patients with TGFβ1 T containing genotypes (CT+TT) (p = 0.001), respectively. The combined unfavorable TNFα (GA/AA) and TGFβ1 (CT/TT) genotypes were highly associated with abnormal liver function parameters and were significantly higher in high activity (A2-A3) and late fibrosis (F2-F4) HCV patients (p = 0.023, 0.029). The multivariate analysis results confirmed that the combined TNFα-308 (AA) and TGFβ1 -509 (TT) unfavorable genotypes increased the risk of hepatic fibrosis progression by 6.4-fold than combined favorable genotypes (odds ratio: 6.417, 95% confidence interval [1.490-27.641], p = 0.013). In conclusion, both TNFα -308 G/A and TGFβ1 -509 C/T polymorphisms synergistically influence the hepatic fibrosis progression and can be used as potential biomarkers to predict hepatic disease progression in chronic hepatitis C patients.

Abstract
It is suggested that interleukin 10 (IL-10), as a modulator of immune response, is likely to influence the elimination of hepatitis C virus (HCV), the progression of chronic hepatitis C (CHC) and the response to interferon-based therapy in CHC patients. The aim of the study was to analyze the association of single nucleotide polymorphisms (SNPs) of IL-10 gene with severity of liver disease (degree of inflammation and stage of fibrosis) and outcome of pegylated interferon alpha and ribavirin combined therapy (sustained virological response (SVR) and relapse) in 196 Polish CHC patients infected with HCV genotype 1. The analysis included IL-10 promoter SNPs: -1082(A/G) rs1800896, -819(C/T) rs1800871, -592(C/A) rs1800872 and SNP in the 3' UTR of IL-10 gene: +4529(A/G) rs3024498. Genotyping was performed using PCR-RFLP and HRM analysis. It was demonstrated that the -592C allele is associated with mild hepatic inflammation. Moreover, it was found that the -819C allele might be associated with SVR and that the ACCA haplotype and intermediate IL-10 producer ACC haplotype are associated with SVR and non-relapse. It can be concluded that IL-10 SNPs are associated with severity of disease and response to therapy and may be considered as potential prognostic and predictive markers in CHC.

Tumor necrosis factor-α -G308A polymorphism is associated with liver pathological changes in hepatitis C virus patients. World J Gastroenterol 2016; 22:7767-7777. [PMID: 27678360 PMCID: PMC5016377 DOI: 10.3748/wjg.v22.i34.7767] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/15/2016] [Revised: 07/05/2016] [Accepted: 08/01/2016] [Indexed: 02/06/2023] Open
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

INFECTION GENETICS AND EVOLUTION 2016; 45:48-55. [PMID: 27543394 DOI: 10.1016/j.meegid.2016.08.016] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/30/2016] [Revised: 07/24/2016] [Accepted: 08/15/2016] [Indexed: 12/31/2022]
Abstract
There are accurate but inconclusive data on the association of interleukin (IL) 10 polymorphisms with sustained virological response (SVR) in chronic hepatitis C (CHC). This meta-analysis aimed to derive a more precise estimation of the effects of IL10 gene polymorphisms (-1082G/A, -819C/T, -592C/A) and their haplotypes on SVR in CHC patients receiving pegylated interferon alpha (PEG-IFN-a) plus ribavirin. Literature search was conducted up to Jan., 2016, in PubMed, EMBASE and ISI Web of Science electronic databases. Statistical analyses were performed by STATA11.0 software, with odds ratios (ORs) and their 95% confidence intervals (CIs). A total of 14 studies involving 1687 CHC cases met the inclusion criteria. Analyses were stratified either by ethnicity or genotype of hepatitis C virus (HCV). The results indicated that IL10-1082A/G was associated with a significantly decreased SVR rate based on the heterozygous model (OR: 0.662, 95% CI: 0.467-0.938) and dominant model (OR: 0.648, 95% CI: 0.440-0.955). Similar results were found in the Egyptian and HCV-4 genotype in all gene models except the recessive model. Moreover, we observed that IL10-819T allele carriers was associated with a significantly increased SVR in the Caucasian population (OR: 1.380, 95% CI: 1.018-1.871). However, we did not detect any significant association of the -592C/A polymorphism or haplotypes with SVR in the total or subgroup populations. In conclusion, IL10-1082GG genotype and -1082G allele were associated with decreased SVR rate in CHC patients, especially for the Egyptian and HCV-4 genotype. Moreover, IL10-819T allele was more likely to get SVR in the Caucasian population.

Abstract
Certain host single nucleotide polymorphisms (SNPs) affect the likelihood of a
sustained virological response (SVR) to treatment in subjects infected with hepatitis
C virus (HCV). SNPs in the promoters of interleukin (IL)-10 (-1082 A/G, rs1800896),
myxovirus resistance protein 1 (-123 C/A, rs17000900 and -88 G/T, rs2071430) and
tumour necrosis factor (TNF) (-308 G/A, rs1800629 and -238 G/A, rs361525) genes and
the outcome of PEGylated α-interferon plus ribavirin therapy were investigated. This
analysis was performed in 114 Brazilian, HCV genotype 1-infected patients who had a
SVR and in 85 non-responders and 64 relapsers. A significantly increased risk of
having a null virological response was observed in patients carrying at least one A
allele at positions -308 [odds ratios (OR) = 2.58, 95% confidence intervals (CI) =
1.44-4.63, p = 0.001] or -238 (OR = 7.33, 95% CI = 3.59-14.93, p < 0.001) in the
TNF promoter. The risk of relapsing was also elevated (-308: OR = 2.87, 95% CI =
1.51-5.44, p = 0.001; -238: OR = 4.20, 95% CI = 1.93-9.10, p < 0.001). Multiple
logistic regression of TNF diplotypes showed that patients with at least two copies
of the A allele had an even higher risk of having a null virological response (OR =
16.43, 95% CI = 5.70-47.34, p < 0.001) or relapsing (OR = 6.71, 95% CI =
2.18-20.66, p = 0.001). No statistically significant association was found between
the other SNPs under study and anti-HCV therapy response.

Abstract
Background The host immune response is an important indicator of the outcome of hepatitis C virus (HCV) infection and disease progression. The aim of this study was to explore cytokine gene polymorphisms as a candidate for susceptibility to persistent HCV infection or HCV spontaneous clearance in a population from Rio de Janeiro, Brazil. Methods Genetic polymorphisms in the cytokines, tumor necrosis factor-alpha (−308), transforming growth factor-beta 1 (codons 10 and 25), interleukin-10 (IL-10; −1082 and −592), IL-6 (−174), and interferon-gamma (+874) were analyzed by polymerase chain reaction sequence-specific primers in 245 patients with chronic hepatitis C (CHC), 41 spontaneous recovery (SR) patients, and 189 healthy volunteers. Further, polymorphisms in IL-28B (rs12979860, rs12980275, and rs8099917) were assessed by real-time polymerase chain reaction in all groups. Results The IL-28B rs12979860 CC and rs12980275 AA genotypes were significantly associated with SR of HCV infection and response to therapy, whereas the C allele of IL-6 (−174) was associated with protection to CHC. A multivariate analysis showed that the male sex and IL-28B rs12979860 CT and TT and transforming growth factor-beta 1 (codon 10) TC genotypes were factors associated with CHC. Additionally, IL-6 (−174) C allele was increased in SR patients compared with patients with CHC. Conclusion IL-28B polymorphisms are associated with spontaneous clearance of HCV and response to therapy in a Brazilian population. Also, IL-6 (−174) C allele is involved in SR and decreased inflammation scores.

Abstract
Although it is not known which antigen-specific immune responses (or if antigen-specific immune responses) are relevant or required for methamphetamine's neurotoxic effects, it is apparent that methamphetamine exposure is associated with significant effects on adaptive and innate immunity. Alterations in lymphocyte activity and number, changes in cytokine signaling, impairments in phagocytic functions, and glial activation and gliosis have all been reported. These drug-induced changes in immune response, particularly within the CNS, are now thought to play a critical role in the addiction process for methamphetamine dependence as well as for other substance use disorders. In Section 2, methamphetamine's effects on glial cell (e.g., microglia and astrocytes) activity and inflammatory signaling cascades are summarized, including how alterations in immune cell function can induce the neurotoxic and addictive effects of methamphetamine. Section 2 also describes neurotransmitter involvement in the modulation of methamphetamine's inflammatory effects. Section 3 discusses the very recent use of pharmacological and genetic animal models which have helped elucidate the behavioral effects of methamphetamine's neurotoxic effects and the role of the immune system. Section 4 is focused on the effects of methamphetamine on blood-brain barrier integrity and associated immune consequences. Clinical considerations such as the combined effects of methamphetamine and HIV and/or HCV on brain structure and function are included in Section 4. Finally, in Section 5, immune-based treatment strategies are reviewed, with a focus on vaccine development, neuroimmune therapies, and other anti-inflammatory approaches.

Abstract
Interleukin-10 (IL-10) is a cytokine that plays an important role in the regulation of the immune system. Gene polymorphisms of IL-10 have been associated with the different expression levels of this cytokine. In hepatitis C virus infection, IL-10 appears to interfere with the progression of disease, viral persistence and the response to therapy. This study investigated genetic variability in the IL-10 gene promoter between patients infected with hepatitis C virus (HCV) and healthy individuals, associating the frequency of polymorphisms with different aspects of viral infection. This is a case-control study with 260 patients who were infected with HCV and 260 healthy individuals. Genotyping of the polymorphisms was performed using the technique of amplification refractory mutation system PCR (ARMS-PCR) for regions of the IL-10 gene promoter (-1082 G/A, -819 C/T, -592 C/A). The frequencies of alleles and genotypes related to polymorphisms in the IL-10 gene promoter showed a higher frequency of the G allele and genotype GG in the -1082 region between the infected group and the control group (p=0.005 and p=0.001, respectively), whereas the AA genotype was significantly more frequent in the control group. The frequencies of the haplotypes GTA and GCC were higher in the group of infected individuals, whereas the haplotype ATA was more frequent in the healthy group (p<0.006). It was also observed that the genotypes GG and AG in the region -1082 were significantly more frequent among patients infected with HCV who were in advanced stages of fibrosis and cirrhosis (p=0.042). No association was observed between polymorphisms of IL-10 and sustained virologic response (SVR).

Abstract
BACKGROUND Previous studies about the association of the interleukin-10 (IL-10) polymorphisms with the progression of liver fibrosis or cirrhosis susceptibility in chronic hepatitis B/C (CHB/C) disease were inconsistent. The aim of this meta-analysis was to derive a more precise estimation of the association. METHODS We searched Medline, PubMed, EMBASE and Web of Science electronic databases using the following key words: liver fibrosis/cirrhosis, IL10, and polymorphism. Statistical analyses were performed by STATA11.0 software, with odds ratios (ORs) and their 95% confidence intervals (CIs). RESULTS 12 independent studies in relation to IL10-1082A/G, -819C/T and -592C/A polymorphisms were included in our study, which consisted of 197 moderate/severe liver fibrosis cases and 426 mild fibrosis controls as well as 536 liver cirrhosis cases and 881 non-cirrhosis controls. The results indicated that a significantly decreased risk of moderate/severe fibrosis was associated with the GCC haplotype (IL10-1082G, -819C and -592C) in the overall CHB/C patients (OR: 0.547, 95% CI: 0.317-0.946, P=0.031). We did not detect any significant association between these polymorphisms and liver cirrhosis susceptibility in the total population or a subgroup of Asians. However, subgroup analyses by different aetiologies showed that the -819T heterozygotes (TC) were associated with a significantly increased risk of HCV-related liver cirrhosis in the Japanese population (OR: 1.254, 95% CI: 1.033-1.522, P=0.022). CONCLUSIONS The putative high IL-10 production haplotype GCC is more likely to be associated with less severe liver fibrosis in CHB/C patients. Additionally, the IL10-819T allele may be a susceptible factor for HCV-related liver cirrhosis in the Japanese population.

Abstract
Increasing evidence suggests that interleukin-10 (IL-10) gene promoter polymorphisms may be associated with chronic hepatitis C virus (HCV) infection and HCV clearance. To more precisely estimate the association between these variants and the risk of HCV infection, we performed a meta-analysis of 26 studies describing the IL-10-1082A/G, -819C/T, -592C/A genotypes, including 4039 chronic HCV infection cases and 2902 controls. When compared with a healthy population, the -1082GG allele had a 43% increased risk of chronic HCV infection in combined populations (GG vs GA + AA: odds ratio (OR) = 1.433, 95% confidence interval (CI) = 1.052-1.952, P = 0.023). In subgroup analysis by ethnicity, a significant increased risk was associated with the -1082GG genotype in the Caucasian population (GG vs AA: OR = 1.390, 95% CI: 1.108-1.744, P = 0.004; GG vs GA + AA: OR = 1.621, 95% CI: 1.267-2.075, P = 0.000). However, no significant association was found in Asian, African or Chinese populations. Moreover, a higher distribution of -592A was found in the spontaneously recovered population (AA vs CC: OR = 0.585, 95% CI = 0.387-0.884, P = 0.011; AA + AC vs CC: OR = 0.738, 95% CI = 0.551-0.988, P = 0.041; AA vs AC + CC: OR = 0.788, 95% CI = 0.664-0.935, P = 0.006) than that in the chronic HCV infection population. In conclusion, the IL-10-1082GG allele may increase the risk of chronic HCV infection in Caucasian population, and people carrying the IL-10-592A allele are more likely to clear HCV spontaneously.

Abstract
BACKGROUND AND AIMS Single-nucleotide polymorphisms (SNPs) in the IL-10 gene (-1082 [rs1800896], -819 [rs3021097], and -592 [rs1800872]) and the IL-28B gene (rs12979860) in adults were shown to be associated with hepatitis C virus (HCV) clearance. The present study aimed to investigate the possible association of SNPs of IL-10 and IL-28B in predicting the treatment response of HCV genotype 4 in pediatric patients. PATIENTS AND METHODS A restriction fragment length polymorphism-polymerase chain reaction and real-time polymerase chain reaction techniques were used to genotype 34 pediatric patients with HCV genotype 4 for IL-10 and IL-28B SNPs, respectively. Patients received pegylated interferon-α/ribavirin for 48 weeks subdivided according to their response to treatment into responders and nonresponders; also, 20 healthy individuals served as controls. RESULTS A significant difference (P < 0.005) was observed in SNP of IL-28B rs12979860 frequencies between responders and nonresponders. In responders, CC genotype had greater frequency than CT and TT genotypes (60%, 30%, 10%), respectively, with C allele in its homozygous (CC) genotype more likely to respond to treatment than in its homozygous (TT) genotypes. SNPs of IL-10 at -819 (rs3021097) showed significant differences in their genotype frequencies between responders and nonresponders to therapy, and TT genotype had greater frequency in responders than CT and CC (55%, 20%, 25%), respectively. Genotypes with T allele (CT/TT) showed higher rates of response than those with no T allele (CC). CONCLUSIONS SNPs of the IL-28B gene at (rs12979860) CC genotype as well as the IL-10 gene SNPs at -819 (rs3021097)TT genotype can be used for predicting response to treatment before patients are prescribed the expensive pegylated interferon-α/ribavirin therapy.

Abstract
BACKGROUND Pathogens that establish chronic infection elicit immune responses with suppressive cytokines dominating over pro-inflammatory cytokines. Chronic hepatitis C virus (HCV) infection, human immunodeficiency virus (HIV) infection and simian immunodeficiency virus (SIV) infection are associated with high levels of antiviral antibodies expressing a common idiotype specifically recognized by the 1F7 monoclonal antibody (mAb). The 1F7 mAb is a murine IgMκ antibody raised against immunoglobulin pooled from the plasma of multiple HIV-infected individuals. In this study, we investigated direct effects of the 1F7 mAb itself on peripheral blood mononuclear cells (PBMC). METHODS Isolated monocytes or PBMC from healthy controls were incubated with the 1F7 mAb or IgMκ mAb control. Cytokine production was measured in cell culture supernatants by ELISA and cells producing interleukin-10 (IL-10) were identified by subset depletion and intracellular flow cytometry. Endotoxin tolerance was assessed by exposing monocytes to lipopolysaccharide (LPS) following 1F7 mAb or IgMκ mAb control pre-treatment and comparing tumor necrosis factor (TNF)-α levels in cell culture supernatants. RESULTS The 1F7 mAb stimulated monocytes and CD36+ lymphocytes to produce IL-10 in a time and dose-dependent manner. Treatment of monocytes with 1F7 mAb also reduced their subsequent responsiveness to LPS stimulation. CONCLUSIONS Induction of antibodies expressing the 1F7 idiotype by chronic pathogens may facilitate IL-10 production and progression to chronic infection. Direct effects of IL-10 from human monocytes stimulated by 1F7-like antibodies, followed by monocyte transition to an alternatively activated phenotype illustrated by endotoxin tolerance, are two complementary features favouring a tolerogenic or non-responsive immunological environment.

Abstract
BACKGROUND Cytokines play a key role in the regulation of immune responses. In hepatitis C virus infection, the production of abnormal cytokine levels appears to contribute in the progression of the disease, viral persistence, and affects response to therapy. Cytokine genes polymorphisms located within the coding/regulatory regions have been shown to affect the overall expression and secretion of cytokines. The aim of the study was to evaluate the association of of IL28B rs12979860, TGF-β1-509, TNF-α 308, and IL-10-1082 polymorphisms with the susceptibility to hepatitis C virus genotype 4 infection and response to pegylated interferon-α and ribavirin therapy. METHODS IL28B, TGF-β1 and TNF-α genes polymorphisms were genotyped using polymerase chain reaction (PCR)-based restriction fragment length polymorphism assay while IL-10 gene polymorphism was detected by sequence specific primer-PCR in 220 healthy individuals and 440 hepatitis C infected patients (220 sustained virological response and 220 non-responder to combination therapy). RESULTS IL28 B CT and TT, TGF-β1 CT and TT and TNF-α AG and AA genotypes were significantly associated with susceptibility to hepatitis C infection and response to therapy. While no association was found between IL-10 gene polymorphism and susceptibility to HCV infection and response to treatment. CONCLUSIONS These results suggested that inheritance of IL28B CT and TT, TGF-β1 CT and TT and TNF-α AG and AA genotypes which appear to affect the cytokine production may be associated with susceptibility to HCV infection and resistance to combined antiviral therapy.

Abstract
BACKGROUND T-helper (Th) lymphocyte cytokine production may be important in the immune pathogenesis of hepatitis C virus (HCV) infections. Th1 cytokines such as; interleukin-2 (IL-2), and interferon gamma (IFN-gamma) are necessary for host antiviral immune responses, while Th2 cytokines (IL-4, IL-10) can inhibit the development of these effector mechanisms. OBJECTIVES The aim of the present study was to assess the serum profile of Th1 and Th2 cytokines in treated and non-treated HCV infected individuals. PATIENTS AND METHODS This study was carried out in 63 HCV infected patients (31 under treatment and 32 untreated) and 32 matched HCV-sero negative healthy subjects. Serum samples were checked with an enzyme-linked immune sorbent assay (ELISA) for IL-2, IL-4, IL-10 and IFN-gamma. RESULTS Levels of circulating IL-2, IL-4, IL-10 and IFN-gamma were significantly elevated in HCV patients versus normal controls (2 822.6 ± 1 259.92 vs. 950.8 ± 286.9 pg/mL; 1 987 ± 900.69 vs. 895.91 ± 332.33 pg/mL; 1 688.5 ± 1 405.1 vs. 519.03 ± 177.64 pg/mL and 1 501.9 ± 1 298 vs. 264.66 ± 71.59 pg/mL, respectively; P < 0.001). The serum levels of all cytokines were significantly lower in the patients under treatment than those of the untreated patients (P < 0.001). CONCLUSIONS On the basis of our data, the simultaneous increase of Th1 and Th2 related cytokines may indicate that both Thl and Th2 cytokines are involved in the pathogenesis of HCV infections. Moreover, this activated T-cell response in HCV infected patients may be regulated by treatment.

Abstract
SUMMARYThe influence of an immunosuppressive cytokine, interleukin-10 (IL-10), on the outcome of hepatitis C virus (HCV) infection has been increasingly reported recently. A number of polymorphisms appear to control the level of IL-10 production. Among them, −592C/A, −819C/T and −1082G/A in the IL-10 gene are three most studied single nucleotide polymorphisms. To provide a more definitive conclusion about their association with the risk of HCV infection, a meta-analysis was performed by combining and summarizing a total of 17 studies. A biological justification for the choice of genetic model was provided. The results indicated no significant association between these IL-10 polymorphisms and the susceptibility to HCV infection [–592C/A: odds ratio (OR) 0·99, 95% confidence interval (CI) 0·78–1·25; –819C/T: OR 0·90, 95% CI 0·69–1·18; –1082G/A: OR 1·34, 95% CI 0·90–2·00]. However, this analysis did not account for the possible risk modifications by other factors, such as ethnicity and virus persistence. Therefore, the effects of ethnicity and virus persistence were investigated using Bayesian meta-regression and subgroup analysis. Finally, an extended case-control association study was conducted in a Chinese population involving 1140 subjects. Both serum level and genotype data of IL-10 −1082G/A were determined. As a result, a low prevalence of G allele was observed. Significantly higher IL-10 production was observed in HCV patients, especially patients with the GG genotype.

Abstract
The clinical outcome of hepatitis C virus (HCV) infection varies between individuals - from spontaneous viral clearance and persistence without complication, to chronic hepatitis, cirrhosis and hepatocellular carcinoma. Also patterns of response to interferon-based anti-HCV therapy are different from person to person. This diversity may be affected by host genetic factors, including alterations in genes encoding cytokines. Interleukin-10, as an anti-inflammatory cytokine and immune response modulator, may influence on HCV infection susceptibility as well as spontaneous and treatment-induced HCV eradication. Moreover, it is stated that IL-10 has antifibrotic properties and play a role in progression of liver disease. This review summarized studies on interleukin-10 gene polymorphisms (mainly promoter SNPs at positions -1082(G/A), -819(C/T) and -592(C/A)), which may determine IL-10 production, regarding susceptibility to HCV infection, course of HCV-related liver disease (fibrosis, cirrhosis, hepatocellular carcinoma, ALT abnormalities), spontaneous viral elimination as well as hepatitis C treatment outcomes. Analysis of hereby summarized studies shows that it is difficult to unambiguously determine the importance of IL-10 polymorphism as a predictor of clinical outcome of hepatitis C and response to anti-HCV therapy before its beginning. Thus, future larger studies need to address these issues. Continuation of studies on interleukin-10 polymorphisms as well as identification of other candidate predictive markers in HCV infection has important practical implications and there is a chance that may contribute to reduce the scale of hepatitis C problem.
