Abstract
BACKGROUND Preeclampsia (PE) is a syndromic disorder that affects 2% to 8% of pregnancies and is diagnosed principally when hypertension appears in the second-d half of pregnancy. WHO estimates the incidence of PE to be seven times higher in developing countries than in developed countries. Severe preeclampsia/eclampsia is one of the most important causes of maternal mortality, associated with 50,000 to 100,000 annual deaths globally as well as serious fetal and neonatal morbidity and mortality, especially in developing countries. Even though evidence from family-based studies suggest PE has a heritable component, its etiology, and specific genetic contributions remain unclear. Many studies examining the genetic factors contributing to PE have been conducted, most of them are focused on single nucleotide polymorphisms (SNPs). Given that PE has a very important inflammatory component, is mandatory to examine cytokine-SNPs for elucidating all mechanisms involved in this pathology. In this review, we describe the most important cytokine-polymorphisms associated with the onset and development of PE. We aim to provide current and relevant evidence in this regard. METHODS We searched English databases such as PubMed and the National Center for Biotechnology Information. The publication time of the papers was set from the establishment of the databases to February 2022. All studies about Th1/Th2/Th17 cytokines polymorphisms were included in our study. RESULTS SNPs in IFN-γ, TNF-α, IL-4, IL-6, IL-10, IL-17A, and IL-22 are associated with the development, early-onset and severity of PE, being the Th1/Th2/Th17 responses affected by the presence of these SNPs. CONCLUSIONS The changes in Th1/Th2/Th17 response modify processes such as placentation, control of inflammation, and vascular function. Nonetheless, association studies have shown different results depending on sample size, diagnostic, and population.

[PMID: 35860261 PMCID: PMC9289468 DOI: 10.3389/fimmu.2022.917383] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2022] [Accepted: 06/13/2022] [Indexed: 11/13/2022] Open
Abstract
ObjectivePreterm birth (PTB) is a typical inflammatory disease with unclear pathogenesis. The studies investigating the relationship between anti-inflammatory factors IL-4 and IL-10 gene polymorphisms and PTB produced conflicting results. This systematic review and meta-analysis aimed to summarize the effects of IL-4 and IL-10 gene polymorphisms and clarify their possible association with PTB.MethodsA systematic literature review was conducted using PubMed, Web of Science, and Cochrane library (up to 02 April 2022). The MeSH terms, related entry terms, and other names in “Gene” database were used to find relevant articles. A fixed- or random-effects model was used to calculate the significance of IL-4 and IL-10 gene polymorphisms, depending on study heterogeneity. The odds ratios (OR) and 95% confidence intervals (CIs) were calculated in the allele, recessive, dominant, co-dominant, and over-dominant models. The Eggers publication bias plot was used to graphically represent the publication bias.ResultsPolymorphisms in two interleukins (IL-4-590C/T (rs2243250) = 5 and IL-10-592A/C (rs1800872), -819T/C (rs1800871) and -1082A/G (rs1800896) = 16) were found in 21 articles. Overall, only the over-dominant gene model AA + GG vs. AG revealed significant association between IL-10-1082A/G (rs1800896) and PTB (OR [95% CI] = 0.87 [0.76, 0.99], p = 0.04). However, in the allele model, recessive model, dominant model, co-dominant model, and over-dominant model, the polymorphisms for IL-4-590C/T (rs2243250), IL-10-592A/C (rs1800872), and IL-10-819T/C (rs1800871) were not found to be associated with the risk of PTB. In gene models, no statistically significant association was found between IL-4-590C/T (rs2243250), IL-10-592A/C (rs1800872), IL-10-819T/C (rs1800871), and IL-10-1082A/G (rs1800896) polymorphisms and PTB in subgroup analyses by racial or control group Hardy-Weinberg Equilibrium (HWE) p-value. Eggers’s publication bias plot and heterogeneity test (I2<50%, p = 0.05) of IL-10-1082A/G (rs1800896) suggested that the funnel asymmetry could be due to publication bias rather than heterogeneity.ConclusionThe current study suggests that the over-dominant gene model AA + GG vs. AG of IL-10-1082A/G (rs1800896) polymorphism may be associated with genetic susceptibility to PTB and may have a protective function against PTB risk. There was unclear association found between IL-4-590C/T (rs2243250), IL-10-592A/C (rs1800872) and IL-10-819T/C (rs1800871) polymorphisms and PTB. Due to the limitations of included studies and the risk of publication bias, additional research is required to confirm our findings.Systematic Review Registrationhttps://inplasy.com/inplasy-2022-4-0044, identifier INPLASY202240044.

Interleukin 10 Polymorphisms as Risk Factors for Progression to Chagas Disease Cardiomyopathy: A Case-Control Study and Meta-Analysis. Front Immunol 2022; 13:946350. [PMID: 35860267 PMCID: PMC9289619 DOI: 10.3389/fimmu.2022.946350] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2022] [Accepted: 06/06/2022] [Indexed: 11/13/2022] Open
Abstract
Background Chagas disease is a lifelong infection caused by the protozoa Trypanosoma cruzi endemic in Latin-America and emergent worldwide. Decades after primary infection, 20-30% of infected people develop chronic Chagas cardiomyopathy (CCC) while the others remain asymptomatic. CCC pathogenesis is complex but associated with sustained pro-inflammatory response leading to tissue damage. Hence, levels of IL-10 could have a determinant role in CCC etiology. Studies with Latin-American populations have addressed the association of genetic variants of IL-10 and the risk of developing CCC with inconsistent results. We carried out a case control study to explore the association between IL-10-1082G>A (rs18008969), -819C>T (rs1800871), -592A>C (rs1800872) polymorphisms and CCC in a population attending a hospital in Buenos Aires Argentina. Next, a systematic review of the literature and a meta-analysis were conducted combining present and previous studies to further study this association. Methods Our case control study included 122 individuals with chronic T. cruzi infection including 64 patients with any degree of CCC and 58 asymptomatic individuals. Genotyping of IL-10 -1082G>A, -819C>T, -592A>C polymorphisms was performed by capillary sequencing of the region spanning the three polymorphic sites and univariate and multivariate statistical analysis was undertaken. Databases in English, Spanish and Portuguese language were searched for papers related to these polymorphisms and Chagas disease up to December 2021. A metanalysis of the selected literature and our study was performed based on the random effect model. Results In our cohort, we found a significant association between TT genotype of -819 rs1800871 and AA genotype of -592 rs1800872 with CCC under the codominant (OR=5.00; 95%CI=1.12-23.87 P=0,04) and the recessive models (OR=5.37; 95%CI=1.12-25.68; P=0,03). Of the genotypes conformed by the three polymorphic positions, the homozygous genotype ATA was significantly associated with increased risk of CCC. The results of the meta-analysis of 754 cases and 385 controls showed that the TT genotype of -819C>T was associated with increased CCC risk according to the dominant model (OR=1.13; 95% CI=1.02–1.25; P=0,03). Conclusion The genotype TT at -819 rs1800871 contributes to the genetic susceptibility to CCC making this polymorphism a suitable candidate to be included in a panel of predictive biomarkers of disease progression.

Abstract
BACKGROUND Pathophysiological mechanisms of post-traumatic stress disorder (PTSD) are elusive and heterogeneous relationships have been reported among PTSD, Interleukin 10 (IL-10), and other factors after stresses. The present study aimed to longitudinally investigate associations of PTSD with environmental factors and genetic variation of rs1800872 at IL-10 gene. METHODS Symptoms of PTSD were measured by PTSD Checklist-Civilian Version (PCL-C) in 462 high school students at 6, 12, and 18 months after Wenchuan earthquake in China. Genotypes of IL-10 rs1800872 were identified by polymerase chain reaction-restriction fragment length polymorphism analysis and verified by DNA sequencing. RESULTS AA homozygotes had higher PTSD prevalence than C allele carriers only at 18 months in male, but not female subjects. PTSD prevalence at 18 months was lowered in all subjects except male AA homozygotes when compared to that at 6 months, and only in female C allele carriers when compared to that at 12 months. PCL-C scores at 18 months were decreased in all students but not in male AA homozygotes when compared to those at 6 months. IL-10 rs1800872 was associated with PTSD at 18 months. Patterns of predictors of PCL-C scores were different between AA homozygotes and C allele carriers at different times during the follow-up. CONCLUSION There were different reciprocal actions of IL-10 rs1800872 with other potential factors or predictors on PTSD in a time-course and gender-dependent manner. Male students with IL-10 rs1800872 AA genotype had higher prevalence and slower recoveries of PTSD at late stage of the follow-up, suggesting requirements of special psychiatric care or drug supplementation at this stage.

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
The discovery of IL-10 more than 30 years ago marked the beginning of our understanding of how cytokines regulate immune responses, based on cross-regulation between Th1 and Th2 cytokines. Although multiple cell types were shown to produce IL-10, its identity as a Th2 cytokine remained strong because it was rigidly associated with Th2 clones in mice, whereas both Th1 and Th2 clones could secrete IL-10 in humans. However, as new Th1/Th2 cell functionalities emerged, anti-inflammatory action of IL-10 gained more attention than its inhibitory effect on Th1 cells, which may occur as an indirect consequence of suppression of APCs. This notion is also supported by the discovery of regulatory T cells, whose suppressor functions involve the mediation of IL-10, among other molecules. From this perspective, we discuss the functionalities of IL-10 by highlighting important differences between mice and humans with an emphasis on the Th1 and Th2 paradigm.

Abstract
Human papillomaviruses (HPVs) are the most common sexually transmitted pathogens worldwide and among the more than 200 identified HPV types, approximately 15 high risk (HR-HPV) types are oncogenic, being strongly associated with the development of cervical cancer, anogenital cancers and an increasing fraction of head and neck squamous cell carcinomas (HNSCC). HPV-associated cervix cancer accounts for 83% of HPV-attributable cancers, and more than two-thirds of those cases occur in developing countries. Despite the high frequency of HPV infections, in most cases, the virus is cleared by the host immune response and only a small proportion of infected individuals develop persistent infections that can result in malignant transformation, indicating that other elements, including biological, genetic and environmental factors may influence the individual susceptibility to HPV-associated cancers. Previous studies have quantified that heritability, in the form of genetic variants, common in the general population, is implicated in nearly 30% of cervical cancers and a large number of studies conducted across various populations have identified genetic variants that appear to be associated with genes that predispose or protect the host to HPV infections thereby affecting individual susceptibility to HPV-associated cancers. In this article, we provide an overview of gene association studies on HPV-associated cancers with emphasis on genome-wide association study (GWAS) that have identified novel genetic factors linked to HPV infection or HPV-associated cancers.

Abstract
BACKGROUND Interleukin 10 has been shown to play a critical role in the regulation of the immune responses in allergic diseases. AIM To investigate if genetic polymorphisms in the promoter region of the IL-10 gene are associated with food allergy (FA) susceptibility in Caucasian pediatric patients with concomitant allergic diseases and IL-10 levels. METHODS The single nucleotide polymorphisms (SNPs) at -1082A > G (rs1800896), -819 T > C (rs1800871), and -592A > C (rs1800872) of 62 pediatric patients with IgE-mediated FA were analyzed and correlated with clinical parameters, serum IgE and IL-10 levels. The results were compared with those of 92 healthy controls without FA, personal and/or family history of atopy. RESULTS Analysis and comparison of genotype distributions, allele frequencies, and haplotypes showed that none of the genotypes confers an increased risk of FA. The genotype -1082 AA in FA patients was associated with moderate to severe symptoms of FA, the development of atopic asthma, and higher levels of IL-10. In a linear regression study, we confirmed that the genotype -1082 AA acts as an independent factor for the higher levels of IL-10. A positive association was also observed between -819T/C and -592 A/C SNPs and later onset of FA. CONCLUSION Polymorphisms in the promoter region of the IL-10 gene are not associated with FA susceptibility in our cohort. In FA patients, -1082 A/G SNPs seem to influence the production of IL-10, the severity of FA symptoms, and the development of atopic asthma in this population.

Abstract
Classical Hodgkin lymphoma (cHL) is a B-cell-derived malignant neoplasia that has a unique histological distribution, in which the scarce malignant Hodgkin and Reed-Sternberg cells are surrounded by nonmalignant inflammatory cells. The interactions between the malignant and inflammatory cells are mediated by aberrantly produced cytokines, which play an important role in tumor immunopathogenesis. Single nucleotide polymorphisms (SNPs) in genes encoding cytokines and their regulatory proteins may influence the peripheral levels of these molecules and affect disease’s pathobiology. In this study, we evaluate SNPs in the promoter regions of the genes encoding for two key cytokines in Hodgkin lymphoma: IL-10 (SNP/pIL10–592, rs1800872; and SNP/pIL10–1082, rs1800896) and TNF-α (SNP/pTNF -238, rs361525; and SNP/pTNF -862, rs1800630), as well as an SNP in the intronic region of the NFκB1 gene (SNP/iNFKB1, rs1585215), an important regulator of cytokine gene expression. We then look to their possible association with clinical and laboratory features in cHL patients. Seventy-three patients with cHL are genotyped by qPCR-high resolution melting. The SNPs’ genotypes are analyzed individually for each SNP, and when more than two allelic combinations are identified, the genotypes are also divided into two groups according to proposed biological relevance. By univariate analysis, patients harboring SNP/pTNF -238 AG genotype more frequently have EBV-associated cHL compared to homozygous GG, whereas the presence of mediastinal disease (bulky and nonbulky) is more common in the pIL10–592 AC/CC group compared to the AA homozygous group. Patients with SNP/iNFKB1 AA genotype more frequently have stage IV and extranodal disease at diagnosis. These results indicate that some SNPs’ genotypes for IL-10 and TNF-α genes are associated with prognostic parameters in cHL. For the first time, the SNP/iNFKB1 is described in association with clinical features of the disease.

Abstract
Acute pancreatitis (AP) is one of the most common gastroenterological indications for emergency admittance and hospitalization. Gallstones, alcohol consumption or the presence of additional initiating factors give rise to a disease with a diverse clinical appearance and a hard-to predict course of progression. One major challenge in the treatment of AP patients is the early identification of patients at risk for the development of systemic complications and organ failure. In addition, 20%-30% of patients with a first episode of AP later experience progress to recurrent or chronic disease. Complex gene-environment interactions have been identified to play a role in the pathogenesis of pancreatitis, but so far no predictive genetic biomarkers could be implemented into the routine clinical care of AP patients. The current review explains common and rare etiologies of acute pancreatitis with emphasis on underlying genetic aberrations and ensuing clinical management.

Abstract
Cervical cancer (CCa) is one of the most common malign diseases in women associated with human papillomavirus (HPV). The virus is an initiating factor, but not sufficient for the development of cervical intraepithelial lesions (CIN) and CCa. The disease might be a result of the influence of host's genetic factors and polymorphisms in inflammatory-related genes that modify the immune response to HPV and attribute to cancer susceptibility. We carried out a study to determine the association between TNF-a-238G/A and TNF-a-308 G/T polymorphisms with HPV-positive CIN and CCa in women living in the Republic of North Macedonia. Using multiplex SNaPshot analysis for single nucleotide polymorphisms (SNPs), we analysed the genotype and allele distributions of TNF-a-238G/A and TNF-a-308 G/T in 134 cases (HPV-positive and histologically confirmed CIN and CCa) and in 113 controls (cytological and HPV-negative women). For further analysis, the case group was stratified in three subgroups (all cases: CINs+ CCa- group; CIN2+ -group and CIN1- group). Data analysed using the odds ratio (OR) and chi-square test showed the frequency of AA genotypes and A alleles are not significantly higher in cases compared to the controls for both SNPs: AA of TNF-a-238 (0.7% versus 0%) and TNF-a-308 (1.5% versus 0.9%) as well as A allelic frequency (3.0% versus 1.7%) and (13.1% versus 10.6), respectively. The comparison of the case's subgroups with the control group did not show a statistically significant difference. Compared to controls, TNF-a-238G/A and TNF-a-308 G/T are not associated with the risk of HPV associated CIN or CCa in the studied women.

Abstract
OBJECTIVES The outcomes of hepatitis B virus (HBV) infection vary substantially among affected individuals, providing evidence of the role of host genetic background in the susceptibility to HBV persistence and the dynamics of liver injury progression to cirrhosis and hepatocellular carcinoma (HCC). METHODS Six single-nucleotide polymorphisms within the interleukin 10 gene (IL10) were genotyped by MALDI-TOF mass spectrometry in 857 patients with chronic HBV infection (CHB), 48 patients with resolved HBV infection, and 100 healthy volunteers. Associations of the selected polymorphisms with susceptibility to chronic HBV infection, liver injury progression, and outcomes were investigated. RESULTS IL10 -819T (rs1800871), -592A (rs1800872), and +504T (rs3024490) alleles were associated with treatment-induced hepatitis B surface antigen (HBsAg) seroclearance. Additionally, IL10 ATAC haplotype increased the chance of HBsAg loss and was significantly more frequent in patients with less liver injury. Moreover rs1800871TT, rs1518110TT, rs1800872AA, and rs3024490TT genotypes were identified as predictors of a lower FIB-4 score (<0.5). CONCLUSIONS This study indicates that polymorphisms within the promoter region and intronic sequences of IL10 are associated with chronicity of hepatitis B and with HBV-induced liver damage.

Abstract
Abdominal aortic aneurysms (AAAs) are focal dilations of the aorta that develop from degenerative changes in the media and adventitia of the vessel. Ruptured AAAs have a mortality of up to 85%, thus it is important to identify patients with AAA at increased risk for rupture who would benefit from increased surveillance and/or surgical repair. Although the exact genetic and epigenetic mechanisms regulating AAA formation are not completely understood, Mendelian cases of AAA, which result from pathologic variants in a single gene, have helped provide a basic understanding of AAA pathophysiology. More recently, genome wide associated studies (GWAS) have identified additional variants, termed single nucleotide polymorphisms, in humans that may be associated with AAAs. While some variants may be associated with AAAs and play causal roles in aneurysm pathogenesis, it should be emphasized that the majority of SNPs do not actually cause disease. In addition to GWAS, other studies have uncovered epigenetic causes of disease that regulate expression of genes known to be important in AAA pathogenesis. This review describes many of these genetic and epigenetic contributors of AAAs, which altogether provide a deeper insight into AAA pathogenesis.

Abstract
Abstract
Background
Chronic inflammation with sustained unregulated immune stimulation in autoimmune rheumatic diseases (ARD) may be a risk factor for developing lymphoproliferative disorders (LPD). Markers of ARD activity as high erythrocyte sedimentation rate or erosive joint diseases and the development of B-symptoms were accounted as risk factors for LPD development. We investigated the association of five inflammatory cytokine genes single nucleotide polymorphisms (SNPs): TNF-α -308G>A; TGF-β1 gene codon 10 T>C and 25 G>C; IL-10 promoter SNPs -1082 A>G, -819T>C, and -592A>C; IL-6 -174G>C; and IFN-γ 874 T>A with the risk of LPD development in ARD patients. The study was conducted on 70 patients divided into group I, 25 ARD patients diagnosed as RA (n = 15) and SLE (n = 10) and with no history of malignancy; group II, 25 patients diagnosed with LPD and had no ARD; and group III, 20 patients diagnosed with both diseases: ARD and LPD. Cytokine genotyping was analyzed by PCR-sequence-specific primer (PCR-SSP).
Results
ARD+LPD patients had significantly higher frequency of TNF-α -308A allele and AA+AG genotype (high TNF-α producers) and IL-10 -1082A allele and AA genotype (low IL-10 producers) than ARD patients (p = 0.003, p = 0.024, p = 0.003, p = 0.03, respectively) with a significantly increased risk of LPD development in ARD patients expressing the corresponding alleles and genotypes. No significant differences were detected in the distribution frequency of either TGF-β1, IL-6, or IFN-γ SNPs between groups I and III or any of the studied SNPs between groups II and III. The distribution frequency of IL-10 ATA haplotype was significantly increased in group III as compared to group I (p = 0.037).
Conclusion
The significantly increased frequency of the high-TNF-α- and low-IL-10-producing alleles and genotypes in ARD patients may participate in the provision of a proinflammatory milieu that eventually increases the risk of LPD development.

Abstract
AIM To investigate the association between interleukin-10 (IL-10) genetic polymorphisms and risk of POAG through a case-control study in a Han population of China. METHODS A total of 210 patients with POAG and 420 normal subjects were recruited during the period from Dec. 2013 to Dec. 2016. The IL-10 -1082A>G (rs1800870), -819T>C (rs1800871) and -592C>A (rs1800872) polymorphisms were determined using iPlex GOLD SNP genotyping analysis (the SequenomMassARRAY® System, Sequenom, San Diego, USA). The association between IL-10 -1082A>G (rs1800870), -819T>C (rs1800871), and -592C>A (rs1800872) polymorphisms and risk of POAG was assessed by singlelogistic regression analysis. RESULTS We observed that those carrying the CC genotype of rs1800871 was associated with an increased risk of POAG when compared with those harboring the TT genotype (OR=1.84, 95%CI=1.01-3.38). Those with AA genotype of rs1800872 had a 10.62 fold risk of POAG in comparison to the CC genotype (OR=10.62, 95%CI, 3.41-33.09). A completely linkage disequilibrium was found between IL-10 rs1800871-rs1800872 (D'=1.00, r 2=0.16). The A-C-A (OR=2.60, 95%CI, 1.48-4.58) and G-T-A (OR=2.34, 95%CI, 1.42-3.86) haplotypes were associated with an increased risk of POAG, while the A-T-C haplotype showed a decreased risk of POAG (OR=0.63, 95%CI, 0.49-0.81). CONCLUSION Our data suggest that IL-10 rs1800871 and rs1800872 can be predictive factors for the pathogenesis of POAG in the Chinese population.

Abstract
AIMS To investigate the association of IL10 SNPs in chronic hepatitis C (CHC) patients with and without the first major depressive episode (MDE), as well as their association with plasma levels of target cytokines. METHODS A hundred and thirty two CHC patients (32 with and 100 without first MDE) and 98 controls were prospectively enrolled in this cross-sectional study. MDE was diagnosed by a psychiatrist, using the Mini International Neuropsychiatric Interview Plus 5.0. IL10 polymorphisms (-1082 G/A, -819C/T and -592C/A IL10 SNPs) were evaluated by Taqman SNP genotyping assay. Plasma concentrations of IL-2, IL-6, IL-10, IFN-γ and TNF-α were determined using the Human Th1/Th2 Cytometric Bead Array kit. The associations were investigated by logistic models. RESULTS The frequencies of the studied IL10 SNPs did not differ between the CHC patients and controls. The first MDE was positive and independently associated with the IL10-1082*A, IL10-819*T and IL10-592*A (ATA) low producer haplotype (OR = 1.50; 95% CI = 1.11-2.04; P = 0.009) and current alcohol misuse (OR = 4.29; 95% CI = 1.22-15.05; P = 0.02), and inversely associated with increasing age (OR = 0.94; 95% CI = 0.91-0.98; P = 0.006). In addition, plasma level of TNF-α was significantly higher in the carriers than in the non-carriers of the IL10 ATA haplotype in patients with the first MDE. The IL-10 and IL-2 plasma levels were significantly higher in the carriers than in non-carriers of the IL10 GCC high producer haplotype, demonstrating the functionality of the studied IL10 polymorphisms. CONCLUSIONS This is the first study to demonstrate that the IL10 low producer ATA haplotype is associated with the first MDE in patients with CHC.

Abstract
Objective: The association of interleukin-10 (IL-10) polymorphism with diabetes and its complication was recently established, while there were few researches considering the potential role of IL-10 in gestational diabetes (GDM). This study aimed to investigate the association between IL-10 gene rs1800896 (−1082 A/G), rs1800871 (−819 T/C), rs1800872 (−592 A/C), and rs3021094 (3388 A/C) single nucleotide polymorphisms (SNPs) and GDM susceptibility. Methods: This study included 72 GDM patients and 100 healthy pregnant women. Direct sequencing of the products from polymerase chain reactions of the extracted genomic DNA from study subjects were conducted for analyzing IL-10 gene polymorphism and further genotype frequencies were compared. Plasma IL-10 concentration was measured by ELISA method. Results: The results revealed no significant difference in −592 A/C, −819 T/C, and −1082 A/G genotypes. Significantly increased prevalence of A allele (P = 0.028, OR = 1.69, 95% CI = 1.081–2.64) and A/A genotype (P = 0.031, OR = 2.881, 95% CI = 1.145–7.250) at a previously un-characterized rs3021094 SNP were discovered in the GDM group. Increased IL-10 levels and insulin resistance were also related to the genotype of rs3021094. The risk of GDM was increased when IL-10 level was over 6.5 pg/ml. Conclusion: Our study demonstrated that A allele and A/A genotype of rs3021094 SNP in IL-10 gene were linked to increased risk for GDM, IL-10 plasma level and insulin resistance, which could be potential targets for early screening and detection of GDM.

[PMID: 30882006 PMCID: PMC6387711 DOI: 10.1155/2019/7682827] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2018] [Revised: 11/21/2018] [Accepted: 12/11/2018] [Indexed: 12/14/2022] Open
Abstract
Sjögren's syndrome (SS) is a chronic autoimmune condition characterized by autoantibody production, sicca syndrome, and periepithelial lymphocytic lesions in target tissues. A predisposing genetic background is likely, and, to date, several polymorphisms in non-HLA genes have been explored with interesting results. We investigated the association between the STAT4, TRAF3IP2, HCP5, and IL10 polymorphisms and SS susceptibility and their possible role in the modulation of clinical and laboratory features. 195 consecutive patients with SS were enrolled and clinical and laboratory data were collected. 248 age- and sex-matched healthy subjects were used as controls. Genotyping was performed by allelic discrimination assays. A case-control association study and a phenotype-genotype correlation analysis were performed. A genetic risk profile was developed considering the risk alleles. Both the variant alleles of rs7574865 in the STAT4 gene and rs3099844 in the HCP5 gene were significantly more prevalent in patients than in controls (OR = 1.91 and OR = 2.44, respectively). The variant allele of rs3024505 of IL10 resulted to be a susceptibility allele (OR = 1.52), while the variant allele of rs1800872 seemed to confer a protective effect for the development of the disease (OR = 0.65). A risk genetic profile showed a higher probability to develop the disease in subjects with at least three risk alleles; subjects with 4 risk alleles were not observed in the controls. HCP5 rs3099844 was associated with anti-SSA (P = 0.006, OR = 3.07) and anti-SSB (P = 0.005, OR = 2.66) antibodies, severity of focus score (P = 0.03, OR = 12), and lymphoma development (P = 0.002, OR = 7.23). Patients carrying the STAT4 rs7574965 variant allele had a higher risk of monoclonal component and leukopenia (P = 0.002, OR = 7.6; P = 0.048, OR = 2.01, respectively). We confirmed the association of SS with the STAT4 and IL10 genes and we describe a novel association with HCP5. In particular, we describe an association of this specific SNP of HCP5 not only with disease development but also with autoantibody production and focus score suggesting a potential contribution of this variant to a more severe phenotype.

Abstract
PURPOSE Chronic hepatitis C (CHC) is associated with a decreased health-related quality of life (HRQOL). More recent studies have pointed toward a genetic basis of patient-reported quality of life outcomes. Taking into account that the influence of single-nucleotide polymorphisms (SNPs) on the HRQOL of CHC patients has not been studied, we investigated the combined IL10-1082G/A, - 819C/T, and - 592C/A SNPs, and IL6-174G/C SNP. We also evaluated the association between demographic, clinical, psychiatric, virological, and genetic variables with domains and summaries of HRQOL in CHC patients. METHODS 132 consecutive CHC patients and 98 controls underwent psychiatric evaluation by using the Mini International Neuropsychiatric Interview. HRQOL was assessed by a generic questionnaire, the Medical Outcomes Study 36-Item Short Form Health Survey (SF-36), and by the specific Liver Disease Quality of Life Questionnaire (LDQOL). IL6 and IL10 polymorphisms were evaluated by Taqman SNP genotyping assay. Multivariate analysis was used to evaluate the associations. RESULTS Major depressive disorder was associated with lower SF-36 and LDQOL scores in seven and ten domains, respectively. Diabetes and hypertension were also associated with reduced HRQOL. CHC patients carrying the combination of IL10 ATA haplotype/IL6-GG genotype had lower scores in the SF-36-physical functioning domain, and reduced scores in the LDQOL effects of liver disease on activities of daily living, quality of social interaction, and sexual function domains than the non-carriers of the combined haplotype/genotype. CONCLUSION This is the first study to demonstrate that combined IL6 high-producer GG genotype and IL10 low-producer ATA haplotype is associated with poorer HRQOL in CHC patients.

Abstract
INTRODUCTION The aim of this review is to investigate IL-10 polymorphisms (-1082 G/A, -819 C/T, and -592 C/A) and their association with susceptibility to JIA. EVIDENCE ACQUISITION A meta-analysis was conducted after database search for relevant articles (MEDLINE and EMBASE). EVIDENCE SYNTHESIS A total of seven studies involving 1495 patients and 1670 controls were considered in the meta-analysis. There was no association between the IL-10 -1082 G/A, -819 C/T, and -592 C/A polymorphisms and JIA in allele contrast and any of the genetic models (allele contrast: odds ratio [OR] 0.90, 95% confidence interval [CI] 0.79-1.02, P=0.09; OR=0.97, 95% CI 0.83-1.13, P=0.68; OR=0.92, 95% CI 0.81-1.06, P=0.24, respectively). In subgroup analysis, none of the subtypes of JIA including systemic, rheumatoid factor (RF)-positive polyarticular, RF-negative polyarticular, and oligoarticular was not significantly associated with IL-10 polymorphism. Meta-analysis of the IL-10 haplotype revealed no association between GCC, ACC, and ATA haplotypes and JIA. CONCLUSIONS This meta-analysis showed that IL-10 polymorphisms were not associated with risk of JIA.

Abstract
Background: Lamnin has important effects on human immunity system. The current study aimed to assess the role of L-leucine-7-amido-4-methyl coumarin 1 gene polymorphisms on hepatitis B virus (HBV) susceptibility. Materials and Methods: The rs20558, rs20563, rs10911193, rs10911251, and rs1413390 polymorphisms were analyzed using polymerase chain reaction (PCR) and PCR-reaction–restriction fragment-length polymorphism and amplification-refractory mutation system-PCR using three different groups including chronic HBV-infected patients, HBV patients who were resolved their infection spontaneously and healthy volunteers. Laminin concentrations were also measured in the blood of these individuals. Results: People with rs20558C, rs20563G, and rs10911193T alleles have an increased risk of HBV infection. Moreover, we found that CGTAT haplotype was more frequent in chronically infected people who could affect the mechanism of disease. Furthermore, there was a significant relationship between laminin concentration and rs20558, rs20563, and rs10911193 genotypes in patients. Conclusion: According to the statistical analysis, rs20558, rs20563, rs10911193 polymorphisms probably, related to the chronic HBV infection. In addition, no association of the rs10911251, rs1413390 single nucleotide polymorphisms with the disease was found.

Abstract
BACKGROUND The level of inflammatory cytokine Interleukin (IL)-10 is increased in patients infected with hepatitis-related acute liver failure (ALF), and this was thought to be because of the regulatory polymorphism in the IL-10 gene promoter region. The present study was designed to analyze the possible association between IL-10 gene promoter polymorphism and acute viral hepatitis (AVH), and ALF. An attempt was made to quantify IL-10 levels at admission, during the hospital stay, and at the final outcome to study its relationship with liver injury among patients with AVH, ALF, and controls. METHODS The study included 40 patients each with ALF and AVH. IL-10 gene promoter polymorphism was detected by the PCR-RFLP method. Quantification of IL-10 was done using commercially available ELISA kits. RESULTS The individuals with -592 AC, -819 TC, -1082 AA genotypes were found to have a significantly higher risk of ALF whereas those with -592 AA and - 819 CC polymorphism were found to be less susceptible. Individuals with - 819 CC were found to be more susceptible to AVH while those with -592 AA and -819 TT were less susceptible as compared to controls. Mean serum IL-10 at admission was significantly elevated in patients with ALF (38.4±11.3 pg/mL) as compared to patients with AVH (16.7±5.4 pg/mL) and control population (8.3±3.6 pg/mL, p < 0.05). CONCLUSION Regulatory polymorphism in the IL-10 gene promoter has a possible and significant association with severity and outcome in patients with AVH and ALF. Raised levels of IL-10 could be predictive of prognosis in patients with ALF.

Abstract
Diabetic retinopathy, a complication of both type 1 and type 2 diabetes, is a complex disease and is one of the leading causes of blindness in adults worldwide. It can be divided into distinct subclasses, one of which is diabetic macular oedema. Diabetic macular oedema can occur at any time in diabetic retinopathy and is the most common cause of vision loss in patients with type 2 diabetes. The purpose of this review is to summarize the large number of genetic association studies that have been performed in cohorts of patients with type 2 diabetes and published in English-language journals up to February 2017. Many of these studies have produced positive associations with gene polymorphisms and diabetic retinopathy. However, this review highlights that within this large body of work, studies specifically addressing a genetic association with diabetic macular oedema, although present, are vastly under-represented. We also highlight that many of the studies have small patient numbers and that meta-analyses often inappropriately combine patient data sets. We conclude that there will continue to be conflicting results and no meaningful findings will be achieved if the historical approach of combining all diabetic retinopathy disease states within patient cohorts continues in future studies. This review also identifies several genes that would be interesting to analyse in large, well-defined cohorts of patients with diabetic macular oedema in future candidate gene association studies.

Abstract
Interleukin-10 (IL10) is an immune regulatory cytokine. Single nucleotide polymorphisms (SNPs) in IL10 promoter have been associated with prognosis in adult classical Hodgkin lymphoma (cHL). We analyzed IL10 SNPs -1082 and -592 in respect of therapy response, gene expression and tumor microenvironment (TME) composition in 98 pediatric patients with cHL. As confirmatory results, we found that -1082AA/AG; -592CC genotypes and ATA haplotype were associated with unfavourable prognosis: Progression-free survival (PFS) was shorter in -1082AA+AG (72.2%) than in GG patients (100%) (P = 0.024), and in -592AA (50%) and AC (74.2%) vs. CC patients (87.0%) (P = 0.009). In multivariate analysis, the -592CC genotype and the ATA haplotype retained prognostic impact (HR: 0.41, 95% CI 0.2-0.86; P = 0.018, and HR: 3.06 95% CI 1.03-9.12; P = 0.044, respectively). Our analysis further led to some new observations, namely: (1) Low IL10 mRNA expression was associated with -1082GG genotype (P = 0.014); (2) IL10 promoter polymorphisms influence TME composition;-1082GG/-592CC carriers showed low numbers of infiltrating cells expressing MAF transcription factor (20 vs. 78 and 49 vs. 108 cells/mm2, respectively; P< 0.05); while ATA haplotype (high expression) associated with high numbers of MAF+ cells (P = 0.005). Specifically, -1082GG patients exhibited low percentages of CD68+MAF+ (M2-like) intratumoral macrophages (15.04% vs. 47.26%, P = 0.017). Considering ours as an independent validation cohort, our results give support to the clinical importance of IL10 polymorphisms in the full spectrum of cHL, and advance the concept of genetic control of microenvironment composition as a basis for susceptibility and therapeutic response.

Abstract
Interleukin 10 (IL-10) is an anti-inflammatory cytokine with a protective role in the formation and the development of the atherosclerotic plaque. The aim of the present study was to establish if IL-10 gene polymorphisms are associated with the development of premature coronary artery disease (pCAD) and cardiovascular risk factors in Mexican individuals. Three IL-10 gene polymorphisms [-592C/A (rs1800872), -819C/T (rs1800871), and -1082 A/G (rs1800896)] and IL-10 plasma levels were analyzed in 2266 individuals (1160 pCAD patients and 1106 healthy controls). Under recessive and co-dominant2 models, the -1082 A/G (rs1800896) G allele was associated with decreased risk of developing pCAD (OR = 0.572, Prec = 0.022 and OR = 0.567, Pcod2 = 0.023). In pCAD patients, the polymorphisms were associated with hyperinsulinemia, small and dense LDLs, hypertension, and diabetes mellitus. In the control group, the polymorphisms were associated with hypertension, hyperuricemia, and small and dense LDLs. pCAD patients have significantly higher IL-10 plasma levels than healthy controls [0.91 (0.55-1.67) pg/mL vs 0.45 (0.24-0.98) pg/mL, respectively, P < 0.0001]. Nevertheless, these levels were not associated with the genotypes analyzed in the present study. The results suggest that the IL-10-1082 A/G (rs1800896) G allele is associated with a decreased risk of developing pCAD. In patients and controls, the polymorphisms analyzed were associated with some cardiovascular risk factors. Although, in pCAD patients the IL-10 plasma levels were higher, they were not associated with the genotypes of the polymorphisms examined.

Abstract
OBJECTIVE To analyze the association of IL-10 gene and its polymorphisms with preterm birth (PTB). METHODS Five hundred and fifty nine women with term birth and 559 with preterm birth were recruited from Lucknow, India. Genetic association analysis was conducted between cases and controls. Subjects recruited as cases were women (aged between 18-40 y) with singleton delivery before 37 wk of gestation and controls were with delivery after or on 37 wk. The genotyping was performed for rs1800871, rs1800872 and rs1800896 for assessing the allelic distribution, haplotypic association and linkage disequilibrium analysis. IL-10mRNA levels were evaluated by real time quantitative polymerase chain reaction (PCR) method. RESULTS The risk of PTB was found significant in women carrying IL-10 (-1082) GA genotype [OR=1.72(1.7-2.5), p=0.006]. The haplotypic analysis of studied polymorphisms for rs1800871, rs1800872 and rs1800896 depicted the association of ATA (p=0.02) and ATC (p=0.01) haplotypes with PTB. The IL-10 mRNA levels were significantly lower in cases (p=0.05). CONCLUSIONS IL-10 marks a protective impact in the inflammatory pathway of PTB.

[PMID: 29467923 PMCID: PMC5805509 DOI: 10.18632/oncotarget.23385] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2017] [Accepted: 12/04/2017] [Indexed: 12/01/2022] Open
Abstract
The current study was designed to quantitatively summarize the evidence for the strength of the associations between common IL-10 functional polymorphisms and skin cancer risk. Relevant publications concerning the associations between common IL-10 functional polymorphisms(−1082G>A, −819C>T and −592C>A) and skin cancer were retrieved by a comprehensive electronic literature search in PubMed, Web of Science, EBSCO, Embase, China National Knowledge Infrastructure, Wanfang, Chinese Biomedical Database (CBM). The odds ratio (OR) and 95% confidence interval (CI) were utilized to assess the strength of the relationship. A total of 26 studies including 4090 cases and 4133 controls (−1082G>A, 10 studies with 1809 cases and 1830 controls; −819C>T, 7 studies with 862 cases and 957 controls; −592C>A, 9 studies with 1419 cases and 1346 controls) were enrolled in the meta-analysis. Overall, the results revealed a borderline decreased risk of skin cancer in heterozygote model (OR = 0.82, 95CI = 0.67–1.00, p = 0.05). The subgroup analysis also presented similar association for non-melanoma skin cancer in heterozygote model (OR = 0.67, 95CI = 0.50–0.91, p = 0.01). Moreover, the further analysis based on the histological type of non-melanoma skin cancer indicated a significantly decreased risk of BCC in allele model (OR = 0.67, 95% CI = 0.50–0.91, p = 0.02) and dominant model (OR = 0.68, 95% CI = 0.48–0.98, p = 0.04). However, neither overall analysis nor subgroup analysis based on cancer subtype revealed a significant association of −1082G>A or −592C>A polymorphisms with skin cancer. The present study suggested a potential association between IL-10 −819C>T polymorphism and decreased risk of skin cancer, but a lack of association for −1082G>A and −592C>A polymorphisms. Further invalidation is urgently needed.

Abstract
Previously, we studied an association of two IL28B gene single nucleotide polymorphisms (SNPs) and three IL10 gene SNPs with predisposition to tick-borne encephalitis in a Russian population. In this study, a possible involvement of these SNPs in the development of predisposition to chronic hepatitis C (caused by structurally similar, related virus from the Flaviviridae family) was investigated in the same population. Only the IL10 promoter rs1800872 SNP was associated with predisposition to chronic hepatitis C. This SNP seems to be a common genetic marker of predisposition to two diseases caused by hepatitis C and tick-borne encephalitis viruses in Russian population.

Abstract
SummaryOne of the most severe and important complication in the treatment of haemophilia A (HA) patients is the formation of inhibitors. The mechanism that leads to factor (F)VIII inhibitor formation is complicated. Both genetic and environmental factors have been mentioned to play decisive roles. Recently, polymorphisms in the genes encoding interleukin-10 (IL-10), tumour necrosis factor-alpha (TNF-α), cytotoxic T-lymphocyte antigen-4 (CTLA-4), have been suggested to be contributing determinants of the inhibitor risk. In order to investigate the influence of the single nucleotide polymorphisms (SNPs) in the genes encoding for cytokines to the inhibitors development in Chinese HA patients, we genotyped 10 SNPs with high heterozygote rates in Chinese and a CA repeat microsatellite at the gene loci IL-10 as well in a separate, unrelated case-controlled cohort of 122 affected HA patients; 63 with inhibitors and 59 without inhibitors. The particular SNPs included in this study were as follows: –592C/A and –819C/T in IL-10, –590C/T in IL-4, –318C/T and 49A/G in CTLA-4, –827C/T in TNF-α, –1112C/T and 2044G/A in IL-13, 874A/T in interferon (IFN)-γ and –295T/C in IL-16. Our results demonstrated that –819T and –592A alleles in IL-10 were observed more frequently in patients with inhibitors. This indicated that –819C/T and –592A/C in IL-10 may influence the inhibitors development in HA patients. Furthermore, we concluded that the haplotype in IL-10 (TA, CA, CC at positions –819 and –582, respectively) may predispose FVIII inhibitor development in HA patients. In conclusion, the data reported in our study clearly highlight the participation of IL-10 in inhibitors formation in Chinese HA patients.

Abstract
Metabolic syndrome (MetS) is an inflammatory disorder, in which various cytokines play important role in tilting balance towards disease state. Interleukin-10 (IL-10) is an important antiinflammatory cytokine, but its genetic polymorphisms and serum levels in Indian MetS subjects are unknown. Three IL-10 gene polymorphisms (-1082A>G (rs1800896), -819C>T (rs1800872) and -592C>A (rs1800871)) were genotyped with PCR-RFLP in MetS subjects (n = 384) and age/sex matched control subjects (n = 386). Serum IL-10 was measured using enzyme-linked immunosorbent assay. Serum IL-10 level was significantly low in MetS subject and significantly correlated with clinicobiochemical parameters of MetS. Of three investigated promoter polymorphisms, IL-10 -819C> T and -592C>A were significantly associated with risk of MetS. The mutant alleles -819T and -592A of IL-10 gene polymorphism were significantly higher in MetS subjects compared to controls. Of the four different haplotypes obtained, common ACC haplotype and rare GTA haplotype of IL-10 polymorphisms were associated with MetS. The mean of fasting insulin and HOMA-IR were significantly different between the genotypes of both -819 C>T and -592C>A polymorphisms of IL-10 in MetS subjects. These results suggested that polymorphisms in IL-10 gene (-819C>T and -592C>A), haplotypes (ACC and GTA) and serum level are significantly associated with risk of MetS. IL- 10 -819C>T and -592C>A polymorphic variants are also significantly associated with insulin level and homeostasis model assessment-insulin resistance in north Indian MetS subjects.

Abstract
Background The etiology of stroke, a severe complication of sickle cell anemia, involves inflammatory processes. However, the pathogenetic mechanisms are unknown. The aim of this study was to evaluate the influence of interleukin-10 polymorphisms and haplotypes on the risk of acute cerebral ischemia and high-risk transcranial Doppler in 395 children with sickle cell anemia from the state of Minas Gerais, Brazil. Methods Interleukin-10 haplotypes were determined by polymerase chain reaction-restriction fragment length polymorphism and sequencing. The outcomes studied were acute cerebral ischemia and high-risk transcranial Doppler. Clinical data were retrieved from the children's records. Results There was no statistically significant difference in the frequencies of polymorphisms and haplotypes between children with and without acute cerebral ischemia or children with or without high-risk transcranial Doppler. These data are consistent with a previous report that showed an absence of association between interleukin-10 plasma levels and high-risk transcranial Doppler velocity in children with sickle cell anemia. Conclusion Interleukin-10 haplotypes were not associated with the risk of acute cerebral ischemia or high-risk transcranial Doppler velocity in children with sickle cell anemia from the state of Minas Gerais, Brazil.

Abstract
Background: Genetic influences on self-medication with over-the-counter (OTC) drugs merit investigation. For example, patients frequently use OTC nonsteroidal anti-inflammatory drugs (NSAIDs) to treat inflammation, but the inflammatory response is also affected by endogenous cytokines whose production varies across polymorphisms of their encoding genes. In the case of interleukin 10 (IL-10), literature suggests that a single nucleotide polymorphism (SNP) in the promoter region of the cytokine’s gene (-1082 A > G [rs1800896]) influences production with higher levels associated with G variant alleles. Objective: To demonstrate the feasibility of researching the role of genetics in self-medication by using existing national survey data to evaluate a possible association between OTC NSAID use and genotype at the -1082 SNP of the IL-10 gene. Methods: Statistical analyses were performed using data from 6,309 participants in the Third National Health and Nutrition Examination Survey (NHANES III). Results: OTC NSAID use (aspirin or ibuprofen) in the previous month was significantly more common among persons with AG or GG genotypes at the -1082 SNP. Odds of use consistently increased relative to the number of G alleles. This trend remained statistically significant (odds ratio = 1.14 per additional G allele, p = .02, 95% confidence interval [1.02, 1.27]) after adjustment for confounding. Conclusions: Analysis of population-based genetic data suggests an association between a common self-medication behavior and a specific genetic polymorphism. These findings broadly demonstrate that NHANES data provide opportunities to investigate such associations and specifically imply that potential interrelationships among OTC NSAID use, IL-10 genotype, and IL-10 cytokine levels deserve further study.

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
Interleukin 10 (IL-10) is an immunomodulatory cytokinethat plays a central rolein the pathogenesis of autoimmune diseases. Different studies consistently show increased IL-10 serum levels in rheumatoid arthritis (RA) and it appears to be caused by genetic variants. Three polymorphisms situated at positions -1082, -819 and -592 of IL10 gene and its major haplotypes have been associated with regulating IL10 promoter activity. In this study, we evaluated whether IL10 haplotypes are associated with mRNA expression and IL-10 serum levels as well as susceptibility to RA in a Western Mexican population. A total of 240 RA patients and 240 control subjects (CS) were included. Genotyping of IL10 polymorphisms was performed by PCR and PCR-RFLP, respectively. IL10 mRNA expression was determined by real-time PCR and IL-10 serum levels were measured using an ELISA kit. IL10 mRNA expression was 50-fold higher in RA patients than CS (p<0.001), while IL-10 serum levels did not show differences between groups. However, high IL-10 serum levels were positively related to a higherseropositivityfor rheumatoid factor (FR) and anti-CCP antibodies (p<0.05). No significant differences between the distribution of haplotype frequencies were observed between both study groups, but GCC haplotype was associated with higher IL-10 serum levels compared with the ACC and ATA haplotypes in RA patients (p<0.05). In addition, patients carrying ATA and GCC haplotypes showed higher mRNA expression than ACC (5.4-fold and 8.8-fold, respectively) and surprisingly, this trend was reversed in the controls, although it was not significant. In conclusion, our findings suggest that IL10 (GCC, ACC, and ATA) haplotypes may not be a susceptibility marker for RA in a population from Western Mexico. Nevertheless, independently of the presence of these variants, there is an aberrant overexpression of IL10 gene in RA, and it may play an important role in the pathogenesis of RA.

Abstract
BACKGROUND The host genetic background regulates the natural history of chronic hepatitis B virus (HBV) infection. OBJECTIVES The aim of this study was to investigate the association between TNF-α gene polymorphism in the promoter region and susceptibility to chronic hepatitis B virus infection. METHODS Four polymorphisms of TNF-α gene including -238 A/G, -308 A/G, -857 C/T, and -863 A/C were analyzed by PCR-RFLP in 100 chronic HBV infected patients (HBV group), 40 spontaneously recovered HBV subjects (SR group), and 100 healthy controls (C group). Also, serum levels of protein were monitored. RESULTS The study showed that the existence of -308 G, -857 C, and -863 A alleles significantly increased susceptibility to chronic HBV infection. In addition, GGCA haplotype had a higher frequency in HBV patients than C and SR groups that might be related to the natural history of the infection. Chronic HBV patients with -308 GG, -857 CC, and -863 AA genotypes had lower serum levels of TNF-α compared to those with other genotypes. CONCLUSIONS The results indicated that there was a positive association between susceptibility to chronic HBV infection and TNF-α polymorphism. In addition, HBV patients carrying -308 GG, -857 CC, and -863 AA genotypes with lower serum levels of TNF-α had an increased risk of infection.

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.

Abstract
BACKGROUND The -819C/T polymorphism in interleukin 10 (IL-10) gene has been reported to be associated with inflammatory bowel disease (IBD), but the previous results are conflicting. MATERIALS AND METHODS The present study aimed at investigating the association between this polymorphism and risk of IBD using a meta-analysis.PubMed, Web of Science,EMBASE,google scholar and China National Knowledge Infrastructure (CNKI) databases were systematically searched to identify relevant publications from their inception to April 2016.Pooled odds ratio (OR) with 95% confidence interval (CI) was calculated using fixed- or random-effects models. RESULTS A total of 7 case-control studies containing 1890 patients and 2929 controls were enrolled into this meta-analysis, and our results showed no association between IL-10 gene -819C/T polymorphism and IBD risk(TT vs. CC:OR=0.81,95%CI 0.64-1.04;CT vs. CC:OR=0.92,95%CI 0.81-1.05; Dominant model: OR=0.90,95%CI 0.80-1.02; Recessive model: OR=0.84,95%CI 0.66-1.06). In a subgroup analysis by nationality, the -819C/T polymorphism was not associated with IBD in both Asians and Caucasians. In the subgroup analysis stratified by IBD type, significant association was found in Crohn's disease(CD)(CT vs. CC:OR=0.68,95%CI 0.48-0.97). CONCLUSION In summary, the present meta-analysis suggests that the IL-10 gene -819C/T polymorphism may be associated with CD risk.

Abstract
Individual variation in immune responses is always encountered after vaccination. This phenomenon is also seen after acellular pertussis vaccination. The aim of this present study was to investigate whether single nucleotide polymorphisms (SNPs) in the IL-10 gene promoter region (rs1800890, rs1800896, rs1800871), IL-12B (rs2546890), IL-12RB1 (rs372889), IL-17A (rs2275913), and IL-23R (rs11209026) affect the immune responses after acellular pertussis vaccination. The T cell proliferative response was evaluated in 38 Finnish young adults who received a second booster dose of a vaccine combination of diphtheria, tetanus, and acellular pertussis, 10 years after the previous booster. The response was evaluated with a proliferation assay in which vaccine antigens pertussis toxin (PT), filamentous hemagglutinin (FHA), and pertactin (PRN) were used for the stimulation, before and 1 month after the second vaccination. Specific proliferation of peripheral blood mononuclear cells against pertussis antigens was affected by IL-10 SNP in the promoter region at position -1082 (A>G, rs1800896). One month after the vaccination, subjects with the AA and AG genotypes had a significantly higher T cell proliferative response against PT and FHA compared to those with the GG genotype. Subjects with the GG genotype had the lowest responses. As a conclusion, our preliminary results indicate that IL-10 SNP -1082 might play an important role in T cell-mediated immune responses after acellular pertussis vaccination.

Abstract
BACKGROUND IL-10 can play a vital role in immune response against HBV. Three biallelic SNPs from the transcription start site control the transcription of the IL-10 gene. An association between susceptibility to HBV and IL-10 polymorphisms has been suggested in patients with HBV infection. OBJECTIVES The present study was designed to study the association between polymorphisms in interleukin-10 (-1082 A/G, -819 T/C and -592 A/C) promoter gene and chronic hepatitis B virus (HBV) infection. PATIENTS AND METHODS 221 chronically infected patients and 200 healthy control subjects were enrolled in the study. Three biallelic (-1082 A/G, -819 T/C and -592 A/C) polymorphisms in the IL-10 promoter gene were determined by PCR-RFLP method. RESULTS Persistent HBV infection was associated with IL-10-1082 AG (P = 0.001) and GG (P = 0.004) genotypes and G (P = 0.000) allele. IL-10-819 T/C and -592 A/C genotype and allele frequencies did not show any correlation with the risk of chronic hepatitis B infection. CONCLUSIONS These results suggest that polymorphisms in interleukin-10 gene promoter influence clinical outcome of HBV infection and susceptibility to HBV infection.

Abstract
BACKGROUND It seems that polymorphism in the regulatory areas of cytokine genes affects the cytokine production capacity and may play a role in the development of infectious diseases. Interleukin-10 (IL-10) and Interleukin-6 (IL-6), which are cytokines of Th2, cause the macrophage become inactive and patient conditions get worse. METHODS In this case-control study, 60 patients with brucellosis and 60 healthy participants were recruited. IL-10 genotyping at positions -1082 (G/A), -819 (C/T), and -592 (C/A) and IL-6 genotyping at position -174 (G/C) were analyzed by amplification refractory mutation system-polymerase chain reaction (ARMS-PCR) and restriction fragment length polymorphism-polymerase chain reaction (RFLP-PCR) methods. The levels of IL-10 and IL-6 were determined by a sandwich enzyme-linked immunosorbent assay in sera of study population. RESULTS The AA and CC genotypes of the IL-10 gene at positions -1082 G/A and -819 C/T were significantly more frequent in patients in comparison to controls, respectively. The AG genotype of the IL-10 gene at positions -1082 G/A was significantly more frequent in control groups than the patients. Serum levels of IL-10 and IL-6 were significantly more frequent in the patients than in the control groups. CONCLUSIONS Our study showed that the AA and CC genotypes at positions -1082 and -819 are very important, respectively. These results suggest that IL-10 (-1082 G/A) GG genotype may be considered as a risk factor for brucellosis, while the AG genotype might be a protective factor against the disease.

Abstract
Rheumatic heart disease (RHD) is an inflammatory disease that develops following streptococcal infections. IL10 helps to balance immune responses to pathogens. IL10 polymorphisms have been associated with RHD, although results remain inconclusive. Our aim was to investigate the association between IL10 polymorphisms and RHD in Saudi Arabian patients. IL10 promoter polymorphisms (-1082A/G, -829C/T, and -592C/A) were genotyped in 118 RHD patients and 200 matched controls using the TaqMan allelic discrimination assay. There was a significant difference in IL10-1082 genotype frequency between patients and controls (p = 0.01). -1082G allele carriage (GG+GA vs AA) and the (-1082, -819, -592) GCC haplotype carriage were associated with an increased risk of RHD (p = 0.004, OR 2.1, 95% CIs 1.7-3.4 and p = 0.004, OR 2, 95% CIs 1.3-3.4, respectively). The ACC haplotype was associated with a decrease in RHD risk (p = 0.015, OR 0.6, 95% CIs 0.4-0.9). IL10 promoter polymorphisms may play an important role in the development of RHD and provide an opportunity for therapeutic stratification.

Abstract
A number of studies have investigated the associations between IL-10 polymorphisms and non-Hodgkin lymphoma (NHL) susceptibility; however, the conclusions were still contradictory. To acquire a more precise estimation of the association, we performed the current meta-analysis. We systematically searched publications from EMBASE and MEDLINE, and calculated pooled odds ratios (ORs) and 95 % confidence intervals (CIs) using either fixed-effects or random-effects model. Genotype-based IL-10 mRNA expression analysis was performed using online public database of 270 individuals with three different ethnicities. A total of 10,703 cases and 11,823 controls from 10 studies were included for the -3575T>A polymorphism, 10,226 cases and 12,215 controls from 17 studies for the -1082A>G polymorphism. Pooled results indicated that IL-10 -3575T>A was associated with increased risk of diffuse large B cell lymphoma (DLBCL) and follicular lymphoma (FL), especially for Caucasians and hospital-based population. There was no association between IL-10 -1082A>G and NHL risk. However, subgroup analysis showed that IL-10 -1082GG might confer increased susceptibility to FL. In summary, this meta-analysis indicated that -3575T>A polymorphism was associated with altered NHL susceptibility for Caucasians and hospital-based population, especially for DLBCL and FL subtypes. The -1082A>G polymorphism may contribute to increased FL risk. Further large-scale population studies among different ethnicities are needed to validate these results.

Abstract
Molecular epidemiological research suggests that interleukin-10 (IL-10) polymorphisms may be associated with an increased risk of head and neck cancer (HNC), but results remain controversial. To derive a more precise evaluation, we performed a meta-analysis focused on genetic polymorphisms of IL-10. PubMed, Embase, CNKI and Wanfang databases were searched for studies that examined the relationship between IL-10 polymorphisms or haplotypes and HNC risk. The odds ratio (OR) and 95% confidence interval (CI) were applied to assess the relationship strength. Publication bias, sensitivity and cumulative analyses were conducted to measure the robustness of our findings. Overall, nine related studies involving 2,258 patients and 2,887 control samples were analyzed. Significant associations between the IL-10-1082A > G polymorphism and HNC risk were observed (G vs. A: OR = 1.56, 95% CI = 1.27–1.92, P < 0.01, I2 = 69.4%; AG vs. AA: OR = 1.64, 95% CI = 1.32–2.05, P < 0.01, I2 = 55.6%; GG vs. AA: OR = 2.24, 95% CI = 1.69–2.97, P < 0.01, I2 = 38.5%; AG + GG vs. AA: OR = 1.70, 95% CI = 1.36−2.14, P = 0.02, I2 = 61.8%; GG vs. AA + AG: OR = 1.89, 95% CI = 1.23−2.90, P = 0.01, I2 = 46.3%) in the total population, as well as in subgroup analysis. Moreover, increased HNC risks were also associated with the IL-10 −819T > C polymorphism and the GCC haplotype. In conclusion, our meta-analyses suggest that IL-10 polymorphisms, specifically the −1082A > G polymorphism, may be associated with increased risk of HNC development.

Abstract
Systemic lupus erythematosus (SLE) is a complex autoimmune disease. Cytokine gene polymorphisms play an important role in SLE. Thus, this study aimed to investigate the associations between interleukin 6 (IL-6) and interleukin 10 (IL-10) promoter single-nucleotide polymorphisms (SNPs) and their susceptibility to SLE and the implications for plasma levels. We genotyped IL-6-174G/C (rs1800795) using mutagenically separated polymerase chain reaction (MS-PCR) and IL-10-1082G/A (rs1800896) and -819C/T (rs1800871) using sequence specific primer polymerase chain reaction (SSP-PCR) in 100 Egyptian patients and 119 controls. The plasma levels of IL-6 and IL-10 were measured by enzyme-linked immunosorbent assay (ELISA). There was significant increase in the frequency of IL-6 (-174) GG genotype ( P < 0.05) and G allele ( P < 0.01) compared to controls. A significant increase in the distribution of IL-10 (-1082G/A) GG ( P < 0.05) and AA ( P < 0.05) genotypes and a significant reduction in the frequency of GA genotype ( P < 0.05) was found in SLE patients. The mean serum concentration of IL-6 ( P < 0.001) and IL-10 ( P < 0.001) was significantly elevated in SLE patients compared to healthy controls. There was no significant association of the most common clinical findings and IL-6 and IL-10 gene polymorphisms in SLE patients. In conclusion, our preliminary study indicated that both GG genotype and G allele of IL-6 (-174G/C) could be considered as risk factors for SLE. In addition, the polymorphisms at IL-10 (-1082 G/G and AA) may play a role in SLE susceptibility in Egyptian patients. Larger prospective studies are needed to confirm our findings.
