Evaluation of genetic polymorphisms in TNF‑α‑308G/A rs1800629 associated with susceptibility and severity of rheumatoid arthritis: A systematic review and meta‑analysis. Exp Ther Med 2024; 28:279. [PMID: 38800041 PMCID: PMC11117118 DOI: 10.3892/etm.2024.12567] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2023] [Accepted: 04/15/2024] [Indexed: 05/29/2024] Open
Abstract
To investigate the association of gene polymorphisms of TNF-α-308G/A rs1800629 with the susceptibility and severity of rheumatoid arthritis (RA), literature from PubMed, EMBASE, Web of Science and CNKI databases was searched. Two authors screened the literature independently, extracted data and evaluated the risk of bias of the included studies. According to the inclusion and exclusion criteria, five genetic models were established: The allelic model (A vs. G), dominant model (GA + AA vs. GG), recessive model (AA vs. GG + GA), co-dominant model (AA vs. GG) and super-dominant model (GG + AA vs. GA). Stata 17.0 software was used for the meta-analysis. A total of 34 eligible studies with 12,611 subjects were included, including 6,030 cases in the RA group and 6,581 controls. Meta-analysis calculations revealed that the genetic polymorphisms of TNF-α-308G/A rs1800629 were not significantly associated with susceptibility to RA, with an odds ratio and 95% confidence interval (CI) for each genetic model [A vs. G: 0.937 (0.762-1.152); GA + AA vs. GG: 0.918 (0.733-1.148); AA vs. GG + GA: 1.131 (0.709-1.802); AA vs. GG: 1.097 (0.664-1.813); and GG + AA vs. GA: 1.108 (0.894-1.373)]. For the association between TNF-α-308G/A rs1800629 gene polymorphisms and the severity of RA, the results of subgroup analysis calculations showed that TNF-α-308G/A rs1800629 gene polymorphisms were associated with the severity of RA in European populations, with the gene model and 95% CI [GA + AA vs. GG: 0.503 (0.297-0.853); and GG + AA vs. GA: 2.268 (1.434-3.590)]. When assessing the confidence in the positive results of the present study through the false-positive report probability, the positive results were observed to be reliable. No significant association was observed between genetic polymorphisms in TNF-α-308G/A rs1800629 and susceptibility to RA. However, a significant association exists with the severity of RA in European populations.

Abstract
BACKGROUND Rheumatoid arthritis (RA) is a systemic autoimmune disease with chronic inflammation. Its pathogenesis involves immunological, genetic, and environmental factors. We investigate the association between Tumor Necrosis Factor α Protein 3 (TNFAIP3), Interleukin 10 (IL10), Tumor Necrosis Factor α (TNF α), and Interleukin 17 F (IL17F) polymorphisms with susceptibility to RA. METHODS AND RESULTS 191 patients with RA diagnosed according to the American College of Rheumatology (ACR)/ European League Against Rheumatism (EULAR) classification and 190 healthy subjects were recruited. Rheumatoid factor (RF), anti-citrullinated peptide antibodies (ACPA), and C-reactive protein (CRP) were measured. Genotyping of the polymorphisms was performed by real-time PCR. Analysis of the allelic frequencies of TNFAIP3 showed a positive association OR (95% CI) = 1.46 (1.01-2.09); p = 0.04, but failed to meet the criteria of significance after Bonferroni Correction. The genotypic and allelic distribution of the IL10, IL17F, and TNFα showed no significant difference when comparing the RA group with controls. Furthermore, the genotype codominant model shows a moderate positive association in the presence of ACPA (OR (95% CI) = 2.82 (1.22-6.24); p = 0.01. None of the polymorphisms studied was associated with RF and CRP production. CONCLUSION Our results show that there is a tendency for the AG genotype of IL10-1082 to be associated with the production of ACPA in patients with RA. None of the variants studied were associated with RA susceptibility in Algerians.

Abstract
Conducted studies highlight that a mixture of genetic and environmental factors is responsible for rheumatoid arthritis (RA) development. This study aimed to analyze the available literature for the relationship between, on the one hand, single-nucleotide polymorphisms (SNPs) in the proinflammatory cytokines genes interleukin-1 (IL-1), -6, -8, -15, -17, -18, and -23, and tumor necrosis factor-alpha (TNF-α), and on the other hand, RA susceptibility, severity, and patients' response to applied treatment. The PubMed database was searched for sources. Preference was given to articles which were published within the past 20 years. Data indicate that the relationship between selected SNPs in proinflammatory cytokines genes and susceptibility to developing RA is inconclusive, and it depends on the ethnicity of the population. Although the allelic and genotypic frequencies of many SNPs in proinflammatory cytokines genes analyzed did not differ between RA patients and healthy controls, deeper analysis showed that these polymorphisms have a relationship with clinicopathological features of RA. SNPs in proinflammatory cytokines genes also "modify patients' response" to applied treatment. Further studies, on larger cohorts of subjects and in different populations, should be conducted to elucidate the role of SNPs in IL-1, -6, -8, -15, -17, -18, and -23, and TNF-α genes in RA patients.

Abstract
Background Rheumatoid arthritis (RA) is characterized by systemic synovitis with bone erosion and joint cartilage degradation. Although the analysis of polymorphisms in cytokine-encoding genes is important or understanding the pathophysiology of RA and selecting appropriate treatment for it, few studies have examined such single-nucleotide polymorphisms (SNPs) specifically in Japanese patients. This study was established to investigate the associations between polymorphisms in cytokine-encoding genes, autoantibodies and therapeutic responses in Japanese RA patients. Methods The subjects in this study consisted of 100 RA patients and 50 healthy controls. We extracted data on sex, age, disease duration, rheumatoid factor (RF), anti-cyclic citrullinated peptide (anti-CCP) antibody, and therapeutic responses, including to methotrexate (MTX) and biological disease-modifying antirheumatic drugs (DMARDs). Genomic DNA was isolated from peripheral blood, which was genotyped for IL-10, TNF-α, TGF-β1, and IFN-γ polymorphisms. Results Regarding IL-10 (−592 C/A and −819 C/T), significant decreases in the frequencies of the IL-10 (−592) CC genotype and (−819) CC genotype were found in RA patients compared with the levels in controls. For IFN-γ (+874 T/A), a significant decrease in the frequency of the TT genotype was found in RA patients compared with that in controls. Regarding TGF-β1 (+869 T/C), patients with positivity for anti-CCP antibody had a significantly lower frequency of the CC genotype than those with negativity for it. Furthermore, the IL-10 (−592) CC genotype and (−819) CC genotype might be related to the biological DMARD-response. Conclusion Our results suggest that the analysis of polymorphisms in cytokine-encoding genes may be useful when selecting treatment for Japanese RA patients.

Abstract
Aim of the study The present case control study was conducted to assess the association of LTA 252 A>G, TNF-α 308 G>A, and TNF-α 1031 T>C gene polymorphisms with rheumatoid arthritis (RA), and their involvement in disease activity and severity. Material and methods A total of 70 Egyptians, including 35 RA patients and 35 healthy control individuals, were included in the study. The RA patients comprised 34 females and one male. Cases with RA were diagnosed by a rheumatologist and fulfilled the 2010 ACR/EULAR criteria. Modified disease activity score (DAS28) was used to assess disease activity. Van Der Heijde-modified Sharp score (vdHSS) was used to assess radiological changes for assessment of disease severity. PCR-RFLP was used to detect the association of LTA 252 A>G, TNF-α 308 G>A, and TNF-α 1031 T>C gene polymorphisms with RA. Results TNF-α 308 G allele and TNF-α 308 GG genotype were significantly higher in RA patients compared to healthy control subjects (p = 0.04 and p = 0.001, respectively). TNF-α 308 G allele and GG genotype were significantly higher in the RA non-remission group compared to the remission group (p = 0.008, p < 0.001). Patients with the TNF-α 308 AG genotype had higher mean of Sharp score compared to the patients with the GG and AA genotypes (p = 0.007). There was no significant association between LTA 252 A>G and TNF-α 1031 T>C gene polymorphisms and RA. Conclusions Our results suggest that TNF-α 308 G/A gene polymorphism is genetically associated with RA and involved in disease activity and severity in Egyptian patients.

Abstract
Tumor necrosis factor-alpha (TNF-α) plays an important role in
autoimmune diseases. Previous studies have investigated the association of
TNF-α-238G/A (rs361525) and -308G/A
(rs1800629) polymorphisms with rheumatoid arthritis (RA) and systemic lupus
erythematosus (SLE). However, no agreed conclusion had been made. Therefore,
this meta-analysis was conducted to assess the associations of
TNF-α-238G/A and -308G/A polymorphisms
with RA and SLE risk. A systematic search was conducted in commonly used
databases. Meta-analysis was performed by STATA12.0. A total of 43 studies were
included. In the overall population, the TNF-α-238A allele was
observed to be a protective factor for RA (A vs G: OR=0.75,
95%CI=0.57–0.99, P=0.040) and the TNF-α-308A allele was found
to be a risk factor for SLE (A vs G: OR=1.78, 95%CI=1.45–2.19,
P<0.001). However, no evidence of association was found between
TNF-α-238 G/A polymorphism and SLE nor between -308G/A and
RA. In the subgroup analysis, TNF-α-308A allele played a
pathogenic role for RA in Latin Americans (A vs G: OR=1.46,
95%CI=1.15–1.84, P=0.002) and for SLE in Latin Americans (A vs
G: OR=2.12, 95%CI=1.32–3.41, P=0.002) and Europeans (A vs G:
OR=2.03, 95%CI=1.56–2.63, P<0.001), while it played a protective role for RA
in Asians (A vs G: OR=0.54, 95%CI=0.32–0.90, P=0.017). No
significant association was found between TNF-α-308G/A and SLE
susceptibility in Africans and Asians. This meta-analysis demonstrated that
TNF-α-238A was associated with decreased risk of RA rather
than SLE, while -308G/A polymorphism was associated with SLE
rather than RA. Stratification analysis indicated that different ethnicities
would have different risk alleles.

Abstract
Tumor necrosis factor (TNF) plays an important role in the pathogenesis of rheumatoid arthritis (RA). Different genetic variants including the TNF -308G/A polymorphism are associated with RA susceptibility. However, these findings have not been replicated in all populations. The aim of this study was to determine whether the TNF -1031T/C (rs1799964), -376G/A (rs1800750), -308G/A (rs1800629) -238G/A (rs361525), and TNFR1 -609G/T polymorphisms are associated with RA susceptibility in a sample of Mexican patients. Our study included 499 patients with RA and 492 healthy controls. The genotypes of the TNF polymorphisms were obtained using TaqMan assay. The genotype and allele frequencies of the TNF -1031T/C, -376G/A, -308G/A, -238G/A, and TNFR1 -609G/T polymorphisms were similar among RA cases versus healthy controls, and no association with RA susceptibility was identified. Our results suggest that the TNF -1031T/C, -376G/A, -308G/A, -238G/A, and TNFR1 -609G/T polymorphisms are not associated with RA susceptibility in a sample of Mexican patients.

Abstract
AIMS We investigated the individual and combined effect of functional TNFA -308G/A and IL10 -1082G/A single nucleotide polymorphisms (SNPs) and their genotypes on the susceptibility to systemic lupus erythematosus (SLE) in a Bulgarian population. MATERIALS AND METHODS Genotyping for -1082A/G IL10 (rs1800896) and -308G/A TNFA (rs1800629) polymorphisms was performed for 154 SLE patients and 224 healthy controls. RESULTS An association between SLE and the rs1800629 polymorphism was established under the allelic model (allele A vs. allele G; odds ratios [OR] = 2.317), the dominant model (GA+AA vs. GG; OR = 3.214), and the overdominant model (GA vs. AA+GG; OR = 3.494). There was no association between rs1800896 and SLE, although a tendency for genetic predisposition to SLE was observed for the IL10 -1082 GG genotype under the recessive genetic model (OR = 1.454). When analyzing the influence of the combined TNFA/IL10 genotypes on SLE occurrence, we found that the carriage of both high cytokine-producing genotypes of two SNPs (TNFA -308AA/GA and IL10 -1082GG) significantly increased the risk of developing SLE with OR of 9.026 (p = 0.006). CONCLUSION Our findings suggest that the combinatorial complexity of TNFA and IL10 promoter polymorphisms impacts SLE susceptibility. Notably, we found that a TNFA promoter polymorphism is a leading risk factor for SLE susceptibility in a Bulgarian population, while the IL10 -1082 locus appears to act as a significant modifier.

Abstract
Tumor necrosis factor alpha (TNF-α) is a proinflammatory cytokine with an important role in the pathogenesis of several diseases. Its encoding gene is located in the short arm of chromosome 6 in the major histocompatibility complex class III region. Most of the TNF-α gene polymorphisms are located in its promoter region and they are thought to affect the susceptibility and/or severity of different human diseases. This review summarizes the data related to the association between TNF-α gene and its receptor polymorphisms, and the development of autoimmune diseases. Among these polymorphisms the -308G/A TNF-α promotor polymorphism has been associated several times with the the development of autoimmune diseases, however some discrepant results have been recorded. The other TNF-α gene polymorphisms had little or no association with autoimmune diseases. Current results about the molecules controlling TNF-α expression are also presented. The discrepancy between different records could be related partly to either the differences in the ethnic origin or number of the studied individuals, or the abundance and activation of other molecules that interact with the TNF-α promotor region or other elements.

Abstract
Objectives This study aims to determine whether promoter -238 G/A polymorphism in tumor necrosis factor-alpha (TNF-α) gene is associated with susceptibility to rheumatoid arthritis (RA) in Iranian population and serum level of TNF-a. Patients and methods This case-controlled study was performed on two groups including 90 RA patients (20 males, 70 females; mean age 50.3 years; range 26 to 65 years) and 90 healthy controls (21 males, 69 females; mean age 48.6 years; range 27 to 63 years). We determined the frequency of -238 G/A TNF-a gene polymorphism by polymerase chain reaction restriction fragment length polymorphism. We measured the serum level of TNF-a using enzyme-linked immunosorbent assay method. Also, we determined the association of serum TNF-a level with the polymorphism in RA patients. Results There was no significant difference in terms of sex and age in the two groups. In the RA group, the genotype frequency of -238 G/A polymorphism was GG (76.6%), GA (17.8%), and AA (5.6%). In the control group, the genotype frequency of -238 G/A polymorphism was GG (83.5%), GA (8.8%), and AA (7.7%). Statistical analysis showed no significant difference in the genotype frequency of this polymorphism between two groups (p=0.07). The serum level of TNF-a were 5.21±1.69 Pg/mL (range 0 to 11.6) in the control group and 62.4±27.1 Pg/mL (range 0 to 117.22) in the RA group (p<0.0001). There was no significant difference in terms of serum TNF-a level and different genotypes in the RA group (p=0.5). Conclusion Our findings demonstrate that the TNF-a -238 G/A gene polymorphism may not represent a significant risk factor for RA in Iranian population and there is no association between the polymorphism and serum TNF-a level in RA patients.

Abstract
Four hundred and ninety-five patients (390 and 105 grafted from unrelated and sibling (SIB) donors, respectively) and their donors were analyzed for the impact of interleukin-10 (IL-10) promoter genotype [rs18000896 (-1082 G/A), rs18000871 (-819 C/T) and rs18000872 (-592 C/A)] on the outcome of hematopoietic stem cell transplantation (HSCT). Patients having ACC haplotype were at a lower risk of acute graft versus host disease (aGvHD, grade > I) if transplanted from human leukocyte antigen (HLA) well-matched (10/10) unrelated donors (20/135 vs 39/117, P < 0.001, Pcorr = 0.002), which was not seen if patients were transplanted from either sibling (SIB) or poorly matched (<10/10) unrelated donors (MUD). In addition, GCC haplotype positive recipients of unrelated donor transplants tended to be more susceptible to aGvHD (68/199 vs 39/169, P = 0.019, Pcorr = 0.057). Multivariate logistic regression analysis in the MUD transplanted group showed that donor-recipient human leukocyte antigen (HLA) mismatch [odds ratio (OR) = 3.937, P = 0.001] and a lack of ACC haplotype in recipients (OR = 0.417, P = 0.013) played a significant role as independent risk factors of aGvHD grade > I. ACC carriers had higher proportions of FoxP3+ lymphocytes gated in CD4+ lymphocytes as compared with patients with other IL-10 haplotypes. It was seen at the time of hematological recovery (mean ± SEM: 3.80 ± 0.91% vs 2.06 ± 0.98%, P = 0.012) and 2 weeks later (5.32 ± 0.87% vs 2.50 ± 0.83%, P = 0.013); -592 C/A polymorphism was separately analyzed and it was found that AA homozygotes tended to have a higher incidence of aGvHD (8/15 vs 116/456, P = 0.034) and low proportions of FoxP3 CD4+ lymphocytes in blood (0.43 ± 0.22% vs 4.32 ± 0.71%, P = 0.051) measured 2 weeks after hematological recovery. Functional IL-10 polymorphism associated features influenced the risk of aGvHD with a positive effect of ACC on the pool of Treg in blood.

Abstract
The major histocompatibility complex (MHC) class I-related chain A (MICA) and B (MICB) are ligands for the natural killer group 2, member D (NKG2D) activating receptor expressed on natural killer (NK) cells, natural killer T (NKT) cells, CD8+ T cells and γδ T cells. Natural killer group 2, member D (NKG2D) ligand expression is stress-related and upregulated by infected or oncogenic cells leading to cytolysis. MICA and MICB genes display considerable polymorphism among individuals and studies have investigated allelic association with disease and relevance of MICA in transplantation, with variable success. It is now known that promoters of MICA and MICB are polymorphic with some polymorphisms associating with reduced expression. We sequenced International Histocompatibility Workshop (IHW) cell line DNA to determine promoter types and alleles encoded by exons 2-6. We found 8 of 12 known MICA promoter polymorphisms and although promoter P7 dominated, other promoters associated with the same allele. For example, MICA*002:01 had promoters P3, P4 or P7 and the common MICA*008:01/04 type had P1, P6 or P7. Similarly, we sequenced 8 of 12 known MICB promoter haplotypes. Some coding region defined MICB alleles had a single promoter, for example, MICB*002:01 and promoter P9, whereas the promiscuous MICB*005 allele had promoters P1, P2, P5, P6, P10 or P12. The results indicate potential for variation in expression of MICA and MICB ligands between individuals with the same allelic types. If differential expression by polymorphic MICA and MICB promoters is confirmed by functional studies, involvement of these genes in disease susceptibility or adverse transplantation outcomes may require knowledge of both promoter and allelic types to make meaningful conclusions.

Abstract
AIM The aim of our study was to determine the genetic associations between polymorphisms of the TNFα gene (-308G/A and -238G/A) with disease susceptibility and severity in patients with rheumatoid arthritis (RA) in an ethnic Kashmiri population. METHODS Allele and genotype frequencies of TNFα-308G/A and TNFα-238G/A polymorphisms were compared between 150 RA patients and 200 healthy controls by using polymerase chain reaction - restriction fragment length polymorphism method. Demographic, clinical and serological data were prospectively evaluated. Disease activity score (DAS28) was also assessed. RESULTS We did not find any significant association between TNFα-308G/A and TNFα-238G/A polymorphism and RA risk (P > 0.05), but TNFα-308GG genotype was associated significantly with rheumatoid factor seropositivity (P < 0.01) and TNFα-238GA genotype was associated with swollen joint count < 5 (P = 0.04) as well as with less severe disease activity as measured by DAS28 score (P = 0.02). CONCLUSION Our findings suggest the possible roles of TNFα-308GG and TNFα-238GA as important determinants for the development of certain manifestations and disease severity in RA in ethnic Kashmiri population.

Abstract
Introduction The goal of this study is to investigate whether the -308G > A promoter polymorphism in the tumor necrosis factor alpha (TNFA) gene is associated with disease severity and radiologic joint damage in a large cohort of patients with rheumatoid arthritis (RA). Methods A long-term observational early RA inception cohort (n = 208) with detailed information about disease activity and radiologic damage after 3, 6 and 9 years of disease was genotyped for the TNFA -308G > A promoter polymorphism (rs1800629). A longitudinal regression analysis was performed to assess the effect of genotype on RA disease severity and joint damage. Subsequently, a meta-analysis, including all publically available data, was performed to further test the association between joint erosions and the TNFA polymorphism. To learn more about the mechanism behind the effect of the polymorphism, RNA isolated from peripheral blood from RA patients (n = 66) was used for TNFA gene expression analysis by quantitative PCR. Results Longitudinal regression analysis with correction for gender and disease activity showed a significant difference in total joint damage between GG and GA+AA genotype groups (P = 0.002), which was stable over time. The meta-analysis, which included 2,053 patients, confirmed an association of the genetic variant with the development of erosions (odds ratio 0.78, 95% CI 0.62, 0.98). No significant differences in TNFA gene expression were observed for the different genotypes, confirming earlier findings in healthy individuals. Conclusions Our data confirm that the TNFA -308G > A promoter polymorphism is associated with joint damage in patients with RA. This is not mediated by differences in TNFA gene expression between genotypes.

Abstract
The objective was to analyze the possible involvement of tumour necrosis factor-alpha (TNF-α) -308 G/A promoter polymorphism in the susceptibility and/or the disease profile of rheumatoid arthritis (RA) in Egyptian patients. TNF-α-308 G/promoter polymorphism detection by amplification refractory mutation system (ARMS) technique was carried out for 122 RA patients and 120 healthy controls. TNF-α-308 G allele/GG homozygous genotype were higher in patients with rheumatoid arthritis than those in control group (P < 0.001, respectively). A statistically significant association was found between the frequency of the A allele and presence of erosion (OR = 3.42, P = 0.015). No associations were found between the distribution of TNF-α-308 G/A alleles/genotypes and age of patients, disease duration, absence of remission, presence of deformity, clinical manifestations of the disease and presence or absence of rheumatoid factor. The positivity of rheumatoid factor was associated with occurrence of erosion (OR = 25.0, P < 0.001). The results of this study demonstrate the association of the TNF-α-308 G allele and GG homozygous genotype with susceptibility to RA and the A allele with the presence of erosion in the Egyptian patients.

Abstract
A large number of studies have shown that the -1082A/G polymorphism (rs1800896) in the Interleukin-10 gene (IL-10) is implicated in the susceptibility to rheumatoid arthritis (RA). However, the results are inconsistent and inconclusive. The aim of this study is to analyze the association between the -1082A/G polymorphism in the IL-10 gene and the RA risk by meta-analysis. A total of 1480 cases and 1413 controls in 10 case-control studies were included in this meta-analysis. The results indicated that the G allele carriers (GG+GA) had a 25% decreased risk of RA, when compared with the homozygote AA (odds ratio (OR)=0.75, 95% confidence interval (CI): 0.59-0.93). In the analysis in Europeans, significant decreased risks were associated with the G allele carriers (OR=0.73 and 95% CI: 0.57-0.93 for GG+GA vs. AA). The results from this meta-analysis provide evidence for the association between the IL-10 -1082A/G polymorphism and the risk of RA. To further evaluate gene×gene and gene×environment interactions between the polymorphisms in the IL-10 gene and RA risk, more studies with large groups of patients are required.

Abstract
BACKGROUND Tumor necrosis factor (TNF)-α and -β are cytokines with a wide range of inflammatory, apoptotic and immunomodulatory activities. TNF-α promoter -308 G < A polymorphism has been reported to be associated with rheumatoid arthritis (RA) with inconsistent results. OBJECTIVE The aim of this study is to elucidate a possible association of TNF-α (G-308A) and TNF-β (A+252G) polymorphisms with the susceptibility of RA in Saudi patients. PATIENTS AND METHODS This case control study consisted of 232 Saudi subjects including 106 RA patients and 126 matched controls. Genomic DNA was extracted using QIAamp(R) DNA mini kit (Qiagen CA, USA). TNF-α and TNF-β genes were amplified using Arms primers. RESULTS The frequencies of TNF-α (-308) allele G and genotype GG were significantly higher in RA patients as compared to controls while allele A and genotype AA were predominant in control group. On the other hand the frequency of TNF-β (+252) GG and AA genotypes were significantly higher in RA patients as compared to controls while GA genotype was predominant in controls. It was inferred that genotype GG positive individuals at position -308 of TNF-α were susceptible to RA while genotype AA might has a protective effect on RA susceptibility in Saudis. Whereas GG and AA genotype of TNF-β at +252 position might exert additive susceptibility to RA and GA might be refractory. However, there was no significant association between duration of morning stiffness, RF positivity and number of joints involved and distribution of alleles/genotypes of TNF-α (-308) or TNF-β (+252) polymorphism. It may be concluded that the TNF-α (-308) and TNF-β (+252) polymorphisms might influence the susceptibility to RA in Saudi population. These results might have prognostic value for future clinical observations.

Abstract
The aim of this study was to determine whether the interleukin-10 (IL-10) polymorphisms confer susceptibility to rheumatoid arthritis (RA). A meta-analysis was conducted on the associations between the IL-10 -1082 G/A, -592 C/A, -892 C/T and IL-10.R polymorphisms and RA using; (1) allele contrast, (2) the recessive model, (3) the dominant model, and (4) the additive model. A total of 16 studies (19 comparisons) involving 2647 RA patients and 3383 controls were considered in the meta-analysis. Meta-analysis of the IL-10 -1082 G/A polymorphism showed no association with RA in the study subjects, or in European or Asian subjects. However, meta-analysis of the -1082 G allele in 4 studies in Hardy-Weinberg equilibrium showed a significant association with RA (OR=1.217, 95% CI=1.027-1.442, P=0.0236). In contrast, meta-analysis of the C allele, the CC genotype, and of the CC versus the AA genotype of the IL-10 -592 C/A polymorphism showed significant associations with RA. The overall ORs of the associations between the C allele and RA were 0.684 and 0.758 (95% CI=0.494-0.946, P=0.022; 95% CI=0.475-1.210, P=0.045) in all study subjects and Asians. Meta-analysis of the CC+CT versus TT genotype and of the CC versus TT genotype of the IL-10 -892 C/T polymorphism revealed significant associations with RA. The overall OR of the association between the C allele carrier and RA was 0.552 (95% CI=0.375-0.812, P=0.003). No association was found between the IL10.R2 alleles and RA. This meta-analysis suggests that the IL-10 -592 C/A polymorphism confers susceptibility to RA in Asians and that the IL-10 -1082 G/A and -892 C/T polymorphisms are associated with RA susceptibility. These findings suggest the IL-10 genes confer susceptibility to RA.

Abstract
Background Various cytokines and inflammatory mediators are known to be involved in the pathogenesis of rheumatoid arthritis (RA). We hypothesized that polymorphisms in selected inflammatory response and tissue repair genes contribute to the susceptibility to and severity of RA. Methods Polymorphisms in TNFA, IL1B, IL4, IL6, IL8, IL10, PAI1, NOS2a, C1INH, PARP, TLR2 and TLR4 were genotyped in 376 Caucasian RA patients and 463 healthy Caucasian controls using single base extension. Genotype distributions in patients were compared with those in controls. In addition, the association of polymorphisms with the need for anti-TNF-α treatment as a marker of RA severity was assessed. Results The IL8 781 CC genotype was associated with early onset of disease. The TNFA -238 G/A polymorphism was differentially distributed between RA patients and controls, but only when not corrected for age and gender. None of the polymorphisms was associated with disease severity. Conclusions We here report an association between IL8 781 C/T polymorphism and age of onset of RA. Our findings indicate that there might be a role for variations in genes involved in the immune response and in tissue repair in RA pathogenesis. Nevertheless, additional larger genomic and functional studies are required to further define their role in RA.

Abstract
Interleukin (IL)-10 is an important multifunctional cytokine with both anti-inflammatory and immunoregulatory effects in rheumatoid arthritis (RA). In the present study, we evaluated the frequency and potential impact of IL-10 promoter polymorphisms on susceptibility to and severity of RA in Polish in - patients with a high disease activity (mean DAS 28 C-reactive protein 5.25). DNA was obtained from 244 RA patients and 106 healthy controls. The -592C/A and -1082G/A IL-10 gene polymorphisms were amplified by polymerase chain reaction with restriction endonuclease mapping. The frequency of the IL-10-592CA, -592AA genotypes (respectively: 30% vs 5% and 7% vs 0%) and allele -592A (37% vs 5%) were significantly higher in RA patients as compared with a control group. We did not find any association of the IL-10-592C/A genotype distribution with disease parameters, except for an increased ESR (erythrocyte sedimentation rate) in patients with the -592CC genotype as compared with those with -592CA or -592AA genotypes (P = 0.01). The frequency of the IL-10-1082GG genotype was lower (P = 0.0001), and that of the IL-10-1082GA genotype was higher (P = 0.009) in RA patients comparing with the control group. In RA patients with -1082GA or -1082AA genotypes the time duration of the disease (P = 0.03), Health Assessment Questionnaire (HAQ) Score (P = 0.04) and PLT count (P = 0.001) were significantly increased as compared with subjects with -1082GG genotype. Presented findings indicate that IL-10-592C/A and IL-10-1082G/A polymorphisms may be considered genetic risk factors for RA susceptibility and severity.

Abstract
We aim to ascertain the possible involvement of functional IL10 and TNF-α promoter polymorphisms on the susceptibility to Behçet's syndrome (BS), to examine whether IL10 and TNF-α genotypes might work synergistically influencing susceptibility to BS. IL10 -1082G/A, -819C/T and -592C/A and TNF -308G/A polymorphisms were analyzed in 102 Turkish patients with BS and 102 healthy subjects by using amplification refractory mutation system-polymerase chain reaction (ARMS-PCR). We have found no significant associations between IL10 -1082G/A, -819C/T, -592C/A, TNF-α -308G/A polymorphisms and BS. Also, no significant correlation was found between IL10 GCC, ACC, ATA haplotypes, GCC(+)/GCC(+), GCC(+)/GCC(-), GCC(-)/GCC(-) genotypes. There was no significant association between combined TNF-α/IL10 genotypes and BS. Our study indicates that functional TNF-α, IL10 genotypes or combined TNF-α, IL10 genotypes do not play a role in BS susceptibility in Turkish BS patients.

Abstract
OBJECTIVE There are dysregulated levels of interleukin 10 (IL-10) and tumor necrosis factor-alpha (TNF-alpha) in rheumatoid arthritis (RA), and their role in the disease is controversial. We analyzed the association of functional polymorphisms of IL-10 and TNF-alpha with susceptibility and disease characteristics at the time of diagnosis, and we also evaluated their possible use as predictors of clinical response to treatments. METHODS Patients with recent-onset RA (n = 162) and healthy controls (n = 373) were genotyped for -1082 IL-10 and -308 TNF-alpha polymorphisms and data were related to clinical and immunological measurements of patients at the time of diagnosis. Response to treatment after 6 months was determined in 125 patients by the absolute change in Disease Activity Score (DAS28) and the American College of Rheumatology criteria for improvement. RESULTS We found a reduced frequency of the low IL-10 producer genotype (-1082AA) in patients with RA compared to controls (26.5% vs 38.9%; p = 0.006), while it is a risk factor for anticyclic citrullinated peptide antibodies (anti-CCP) positivity (p = 0.028). Evaluation of clinical response to treatments indicated that carriage of the high IL-10 genotype was associated with a favorable outcome (p = 0.009), specifically to prednisone therapy (p = 0.0003). No significant effects were observed with TNF-alpha polymorphism alone; however, in combination with the IL-10 genotype, it increased the strength of these associations. CONCLUSION Results show an association between the low IL-10 producer genotype and protection from RA; nevertheless, when other specific genetic and/or environmental factors trigger onset of RA, this genotype may predispose to development of anti-CCP+ RA disease with reduced response to prednisone treatment.

Abstract
Besides atherosclerosis and lung cancer, smoking is considered to play a major role in the pathogenesis of autoimmune diseases. It has long been known that there is a connection between rheumatoid factor-positive rheumatoid arthritis and cigarette smoking. Recently, an important gene-environment interaction has been revealed; that is, carrying specific HLA-DRB1 alleles encoding the shared epitope and smoking establish a significant risk for anti-citrullinated protein antibody-positive rheumatoid arthritis. We summarize how smoking-related alteration of the cytokine balance, the increased risk of infections (the possibility of cross-reactivity) and modifications of autoantigens by citrullination may contribute to the development of rheumatoid arthritis.
