Abstract
PURPOSE Tumor necrosis factor alpha (TNF-α) is an inflammatory cytokine which may play a role in the development of gastric cancer (GC). This study aimed to investigate the association of five TNF-α polymorphisms including TNF-α-857, TNF-α-1031, TNF-α-863, TNF-α-308, and TNF-α-238 polymorphisms with GC risk. METHODS All eligible case-control studies were collected by searching PubMed, Scopus, and Web of Science. The association of the risk of GC with TNF-α polymorphisms was estimated using odds ratio (OR) and 95% confidence interval (CI). Heterogeneity was assessed via Cochrane's Q and I2 analyses. RESULTS A total of 46 publications involving 16, 715 cases with GC and 27, 998 controls were recruited. The study revealed a significant association for TNF-α 308 (recessive model: OR = 0.646, P = 0.035), TNF-α-1031 (homozygote model: OR = 1.584, P = 0.027), and TNF-α-857 (homozygote model: OR = 1.760, P = 0.001) polymorphisms with the GC risk. The results of subgroup analysis based ethnicity found a significant association between GC risk and TNF-α-857 polymorphism in Caucasian subgroup (P = 0.005) and TNF-α-1031 polymorphism and GC risk in Asians (P = 0.018). CONCLUSIONS This study suggested that TNF-α-857 and TNF-α-1031 polymorphisms may be associated with the increased gastric cancer risk.

Association of polymorphisms in TP53 and the promoter region of IL10 with gastric cancer in a Kazakh population. Bosn J Basic Med Sci 2020; 20:539-546. [PMID: 32651972 PMCID: PMC7664782 DOI: 10.17305/bjbms.2020.4761] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2020] [Accepted: 07/02/2020] [Indexed: 12/19/2022] Open
Abstract
The emerging evidence indicates that single nucleotide polymorphisms (SNPs) of the tumor necrosis factor (TNF), interleukin 10 (IL10), tumor protein p53 (TP53), and cluster of differentiation 14 (CD14) genes may determine individual susceptibility to gastric cancer (GC). We aimed to investigate the associations for polymorphisms of the TNF, IL10, TP53, and CD14 genes in a population of Kazakhs, to identify potential risk or protective associations of the SNPs with GC. A case group of 143 patients hospitalized for GC was enrolled. Controls were 355 volunteers with no history of any cancer and frequency matched with cases by age. Differences in proportions for categorical variables and the assessment of genotypic frequencies conforming to the Hardy-Weinberg equilibrium law were evaluated by the Chi-square test. Associations between genetic polymorphisms and the risk of GC were estimated by regression analysis. For genetic analysis, three genetic models (additive, dominant, and recessive) were used. Four significant associations were found. The SNPs rs1042522 of TP53 and rs1800896 of IL10 were risk factors for GC by the additive model. Two polymorphisms of IL10 were protective of GC, namely, rs1800872 by additive model and rs1800871 by recessive model. No significant associations were observed between the TNF and CD14 polymorphisms and GC. The polymorphisms TP53 rs1042522 and IL10 rs1800896 are associated with GC risk, while the polymorphisms IL10 rs1800872 and rs1800871 are protective of GC in the population of Kazakhs.

Association of tumor necrosis factor alpha gene polymorphisms with Helicobacter pylori infection in dyspeptic patients in Sri Lanka. Microbiol Immunol 2018; 62:429-435. [PMID: 29704402 DOI: 10.1111/1348-0421.12597] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2018] [Revised: 03/27/2018] [Accepted: 04/26/2018] [Indexed: 11/29/2022]
Abstract
Single nucleotide polymorphisms present on the promoter sequence of the TNF-α gene may affect production of TNF-α, a pro-inflammatory cytokine, during immune responses. The presence of TNF-α polymorphisms is also reportedly associated with more severe manifestations of Helicobacter pylori infection. However, the frequency of TNF-α polymorphisms and the associated disease severity vary between different patient groups. In this study, gastric biopsies and blood specimens were collected from 138 patients with dyspepsia undergoing routine upper gastrointestinal endoscopy. Our institution's Ethics Review Committee approved the study and written informed consent was obtained from all participants. The presence of H. pylori was confirmed histologically in all patients. The frequency of TNF-α polymorphisms in the study cohort was investigated using PCR-restriction fragment length polymorphism and expression of serum TNF-α quantitated using a commercial ELISA assay. The proportions of selected TNF-α polymorphisms (TNF-α -238, -308 and -863) were similar in H. pylori-positive and -negative patients. Homozygous mutations of TNF-α polymorphisms were rarely detected in the study group. There was a significant difference in TNF-α concentrations between patients with mild chronic gastritis and TNF-α -308 GG genotype and patients with moderate to severe chronic gastritis (P = 0.008). It was not possible to identify an association between these genotypes and disease severity because of the low frequency of heterozygous and homozygous mutated genes in Sri Lankan patients with dyspepsia.

Abstract
The aim of the present study was to evaluate the relationship between tumor necrosis factor-α (TNF-α) and the development of gastric cancer, and to investigate whether it can be used as a biological marker for gastric cancer. In the current study, a new meta-analysis was performed to assess the association between TNF-α gene polymorphisms and gastric cancer susceptibility. Subgroup analyses based on ethnicity, control population source and non-cardia cancers were also conducted. Summary odds ratios (ORs) with 95% confidence intervals (CIs) were calculated using a random-effects model. TNF-α 308 polymorphisms indicated a significant relationship with gastric cancer risk among a normal population [GA/AA vs. GG; 1.17 (1.10–1.23)]. In analysis stratified by ethnicity, TNF-α 238 displayed an association with gastric cancer risk in eastern populations [GA/AA vs. GG: 1.24 (1.02–1.50)], but not in western populations [GA/AA vs. GG: 0.96 (0.79–1.18)]. The overall ORs (95% CIs) for TNF-α 857, TNF-α 1031 and TNF-α 863 were 1.13 (1.04–1.24), 0.94 (0.85–1.05) and 0.89 (0.78–1.02), respectively, under dominant genetic model comparison. Among the above three SNPs, only TNF-α 857 was robustly associated with gastric cancer inclination, and this association remained consistently robust when limited to non-cardia gastric cancers [GA/AA vs. GG: 1.16 (1.03–1.31)]. TNF-α 308 and TNF-α 857 genotypes were potential risk factors of statistical significance in gastric cancer, and TNF-α 238 indicated to be significantly associated with gastric cancer risk only in eastern populations. TNF-α 1031 and TNF-α 863 were not significantly associated with gastric cancer risk.

Abstract
BACKGROUND Although many studies have investigated the association of a single nucleotide polymorphism in TNF-α G-308A gene with depression, their association is still controversial. To clarify this, we performed a meta-analysis. METHOD Studies related to TNF-α G-308A and depression were retrieved from PubMed, Medline, Embase, and Scopus (up to April 18, 2017). The odds ratios (ORs) and 95% confidence intervals (CIs) were estimated in the models of allele comparison (G vs A), homozygote comparison (GG vs AA), dominant (GG vs GA + AA), and recessive (GG + GA vs AA) to estimate the strength of the associations. RESULTS A total of 10 case-control studies were included in this meta-analysis. Overall, no significant association between TNF-α G-308A and depression was found (G vs A: OR [95% CI] =1.09 [0.92, 1.29]; GG vs AA: 1.24 [0.71, 2.15]; GG vs GA + AA: 1.01 [0.76, 1.35]; GG + GA vs AA: 1.22 [0.70, 2.13]). In subgroup analyses by ethnicity or age group, no statistically significant association between TNF-α G-308A polymorphisms and depression was shown. CONCLUSION This meta-analysis revealed that TNF-α G-308A polymorphism is not associated with susceptibility to depression.

Abstract
Many studies have investigated the association between Tumor necrosis factor-α-308 G>A (rs1800629) and the risk of esophageal cancer. However, their results are inconsistent. Therefore, we performed a meta-analysis of available data to investigate any possible association between this polymorphism and esophageal cancer risk. We searched PubMed, EMBASE, Web of Science, and the CNKI database for articles published up to 2016. Crude and adjusted odds ratio with 95% confidence intervals were calculated using fixed or random effects models. We used a dominant model (GA+AA vs GG), a recessive model (AA vs GG+GA), an over-dominant model (GG+AA vs GA), and allele frequency (G vs A) to identify any association. Eleven studies with 5617 participants were included in the meta-analysis. Our results suggest that TNF-α-308 G>A (rs1800629) is not significantly associated with a risk of esophageal squamous cell carcinoma and esophageal adenocarcinoma. For genetic association studies, negative results of meta-analysis have a high level of evidence, and these results are important in this era of high-throughput sequencing-based precision medicine.

Abstract
Background Several host genetic factors are thought to affect susceptibility to Helicobacter pylori infection-related diseases, including tumor necrosis factor (TNF)-α. Previous studies have evaluated the association between TNFA gene polymorphisms and H. pylori infection, but the results were inconclusive. We conducted this meta-analysis to clarify the association between TNFA polymorphisms and H. pylori infection. Methods Published literature within PubMed, Embase, and the Cochrane Library were used in our meta-analysis. Data were analyzed with the Stata13.1 software package using pooled odds ratios (ORs) with 95% confidence intervals (CI). Results A total of 24 studies were included in our study. The TNFA -308G>A polymorphism was associated with decreasing H. pylori infection (AA vs. AG+GG, OR = 0.64, 95% CI = 0.43–0.97; AA vs. GG, OR = 0.64, 95% CI = 0.43–0.97). A significantly decreased risk was also found for -1031T>C polymorphism (CC vs. CT+TT, OR = 0.61, 95% CI = 0.44–0.84). -863C>A polymorphism was associated with increasing risk of H. pylori infection (AA+AC vs. CC, OR = 1.47, 95% CI = 1.16–1.86; A allele vs. C allele, OR = 1.40, 95% CI = 1.14–1.72). There was no significant association between -857C>T polymorphism and H. pylori infection. When stratified analysis was conducted on H. pylori infection detection methods, -857C>T and -863C>A polymorphisms were associated with H. pylori infection for the non-ELISA subgroup. When stratified for ethnicity or study design, -863C>A significantly increased the risk and -1031T>C decreased the risk for the Asian subgroup and hospital-based subgroup. Conclusion Results of our meta-analysis demonstrate that TNFA -308G>A and -1031 T>C polymorphisms may be protective factors against H. pylori infection, and -863C>A may be a risk factor, especially in Asian populations. Further studies with larger sample sizes are required to validate these results.

Abstract
Polymorphisms in tumor necrosis factor alpha (TNF-α) gene are emerging as key determinants of gastric diseases. The TNF-α−308 (G/A) and TNF-α−238 (G/A) single-nucleotide polymorphisms SNPs are the most extensively studied. However, all these studies are conducted in Caucasian and Asian populations. Thus, for the first time in Africa, we sought to investigate whether polymorphisms in TNF-α gene were associated with the development of gastric pathology in Morocco. Two SNPs located in the promoter region (positions −308 and −238) in TNF-α gene were genotyped in 244 individuals (170 patients and 74 healthy controls). Odds ratios (ORs) and 95% confidence intervals (CI) were estimated using logistic regression analysis. The TNF-α−238 (G/A) genotype was significantly associated with a high risk of gastritis and gastric cancer (GC) (P = 0.001 and P = 0.002, resp.). Furthermore, a new polymorphism located in the promoter region at position −193 in TNF-α gene was identified. The distribution of this SNP was markedly different in patients suffering from ulcers. The association between TNF-α−193 (G/A) genotype and high risk of ulcer was significant (P = 0.03). These results suggest that the TNF-α−193 (G/A) allele has a protective function against gastric cancer by developing ulcer.

Abstract
BACKGROUND Tumor necrosis factor-alpha (TNFα) is an important inflammatory mediator in psoriasis and several genetic polymorphisms of this cytokine have been reported. Majority of studies have focused on the increased G- A polymorphism at the -308 position in psoriasis. There has been no comprehensive study evaluating the genetic polymorphisms, TNFα expression in the skin and histopathology. We are undertaking this study to outline TNFα genetic polymorphisms, its skin expression and histopathological correlation to help determine its role at the genetic and protein level. MATERIALS AND METHODS 112 patients of psoriasis and 243 healthy controls were included in this prospective study. 5 ml of peripheral blood was collected to study the TNFα genetic polymorphisms by polymerase chain reaction and restriction fragment length polymorphism analysis. Histopathological analysis of biopsies from the 112 patients were done using visual analogue scale and correlated with the findings. 61 of these cases were analyzed for TNFα expression by immunohistochemistry. The results of study were statistically analyzed using SPSS 13.0 statistical package program. RESULTS A strong association of TNFα -308 G/A polymorphism in psoriasis cases was detected. The A allele of the TNFα -308 G/A polymorphism occurs rarely in the Indian population, however there is an over representation of this allele in psoriatic patients. There was no association seen between TNFα genotype and histopathological severity of psoriasis. CONCLUSION The study emphasized the central role of TNFα in the pathogenesis of psoriasis. TNFα genotyping may be helpful in identifying subjects in whom anti-TNFα therapeutic strategies may be tried.

Abstract
OBJECTIVE Tumor necrosis factor-alpha (TNF-α) has been found to be associated with gastric carcinogenesis, but individually published results have been inconclusive. The aim of this study was to explore the relationship between the TNF-α-308 G/A polymorphism and gastric cancer risk. METHODS MEDLINE, EMBASE and the COCHRANE library databases were searched for relevant articles to identify all available data. The odds ratios (ORs) with 95% confidence intervals (95% CIs) from each study were used to assess the association between the TNF-α-308 G/A polymorphism and gastric cancer risk. RESULTS This meta-analysis included 30 studies (32 datasets) involving 7009 gastric cancer cases and 12,119 control subjects. Overall, a significant association was found between the TNF-α-308 G/A polymorphism and gastric cancer in AA+GA vs. GG (dominant contrast model) (OR=1.20, 95% CI=1.07-1.34, p=0.001). With stratification based on ethnicity, the TNF-α-308 G/A polymorphism was correlated with gastric cancer risk in Caucasians, using the dominant contrast model (OR=0.74, 95% CI=0.57-0.96, p=0.02), but not in East Asians and other ethnic groups. In the comprehensive subgroup analysis, a significant association was also found in recent articles (published after 2005), population-based high-quality studies, hospital-based high-quality studies, studies using the TaqMan method and non-cardia subgroups. However, the TNF-α-308 G/A polymorphism was not associated with specific histological types of gastric cancer risk. CONCLUSIONS The TNF-α-308 G/A polymorphism may contribute to susceptibility to gastric cancer in Caucasians, especially for non-cardia gastric cancer, as most strongly demonstrated in high-quality studies and in studies using the TaqMan genotyping method. Furthermore, we recommend the TaqMan method as the preferred genotyping method in DNA polymorphism studies.

[PMID: 24409077 PMCID: PMC3882423 DOI: 10.3748/wjg.v19.i48.9461] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/02/2013] [Revised: 10/11/2013] [Accepted: 11/05/2013] [Indexed: 02/06/2023] Open
Abstract
AIM: To evaluate the association between the tumour necrosis factor alpha-308 (TNF-α-308) gene polymorphism and the risk of digestive system cancers.
METHODS: All eligible case-control studies published up to December 2012 were identified by searching PubMed, Web of Science, Embase and China National Knowledge Internet without language restrictions. The risk of digestive system cancers associated with the TNF-α-308 polymorphism was estimated for each study using odds ratio (OR) together with its 95%CI, respectively. Cochrane Collaboration RevMan 5.1 was used to perform the analysis. A χ2-test-based Q statistic test and an I2 test were performed to assess the between-study heterogeneity. When the Q test was significant (P < 0.05) or I2 > 50%, the random effects model was used, otherwise the fixed effects model was used.
RESULTS: Fifty-eight studies from fifty-five publications with a total of 9986 cancer patients and 15511 healthy controls were included. Overall, a significant association was found between the TNF-α-308 polymorphism and the risk of digestive system cancers [dominant model: OR = 1.23, 95%CI: 1.09-1.39, (G/A) vs (G/G): OR = 1.15, 95%CI: 1.02-1.28, (A/A) vs (G/G): OR = 1.44, 95%CI: 1.19-1.73, recessive model: OR = 1.38, 95%CI: 1.15-1.66]. Furthermore, when the analysis was stratified by ethnicity, similar results were observed in both the Asian and Caucasian populations, except for the dominant model and heterozygote comparisons in the Asian population [dominant model: OR = 1.24, 95%CI: 0.99-1.56, (G/A) vs (G/G): OR = 1.09, 95%CI: 0.96-1.24]. When the cancer type subgroups were examined, similar results were detected in gastric and hepatocellular carcinomas; however, no significant association was observed among other digestive system cancers.
CONCLUSION: The TNF-α-308 gene polymorphism may be significantly associated with the risk of gastric and hepatocellular carcinomas, but not colorectal, pancreatic, or oesophageal cancer, in the Asian population.

Abstract
Tumor necrosis factor alpha (TNFA) is an important molecule in inflammatory, infectious, and tumoral processes. Inflammation is one of the early phases in the development of gastric cancer (GC). Therefore, several studies have examined the association of polymorphism in TNFA with gastritis and GC risk. A functional polymorphism, -308G>A (rs1800629), which is located in the promoter of TNFA gene, has been suggested to alter the production of TNF-α and influence cancer risk. To date, a number of studies have been carried out to investigate the relationship between the polymorphism and gastritis or GC susceptibility, but the results were conflicting. To investigate this inconsistency, we performed a meta-analysis of 36 studies for TNFA -308G>A polymorphism to evaluate the effect of TNFA on genetic susceptibility for gastritis and GC. An overall random-effects per-allele odds ratio of 1.16 (95 % confidence interval 1.04-1.29, P = 0.008) was found for the polymorphism. Significant results were also observed using dominant or recessive genetic models. In the subgroup analyses by ethnicity, significant results were found in Caucasians, whereas no significant associations were found among East Asians and other ethnic populations. No associations between the polymorphism and gastritis were observed. In addition, our data indicate that TNFA is involved in GC susceptibility and confers its effect primarily in diffuse type of tumors. Besides, -308G>A polymorphism was found to be significantly associated with both cardiac and noncardiac tumors. This meta-analysis demonstrated that the TNFA -308G>A polymorphism is a risk factor for developing GC, but the associations vary in different ethnic populations.

Abstract
BACKGROUND AND AIMS Costa Rica has among the highest incidence and mortality rates for gastric cancer worldwide. The reasons for this are largely unknown. Polymorphisms of inflammatory response genes including genes encoding heat shock proteins (HSP) have been shown to be associated with the risk of gastric cancer in some populations. This study addresses the possible association between the HSP70-2 +1267 and HSP70-Hom +2437 polymorphisms and the risk of developing gastric cancer in a high-risk population in Costa Rica. METHODS DNA from 39 individuals diagnosed with gastric cancer, 79 healthy controls, 55 individuals with chronic gastritis and 52 individuals with duodenal ulcer was genotyped for the polymorphisms HSP70-2 +1267 and HSP70-Hom +2437 by RFLP. Logistic regression analysis was used to determine possible associations with the diagnoses and lineal regression analysis to determine associations with blood pepsinogen (PGs) levels as measured by serology. RESULTS The GA genotype of HSP70-2 was associated with increased risk of gastric cancer (OR = 3.42; 95% CI = 1.27-9.21; p = 0.015) and duodenal ulcer (OR = 2.57; 95% CI = 1.03-6.36; p = 0.042) as compared to the GG genotype. Persons with C carrier genotypes of HSP70-Hom were significantly less susceptible to gastric cancer than those with the TT genotype (OR = 0.29; 95% CI = 0.09-0.87; p = 0.027). The C carrier genotype was associated with lower PGI concentrations but none of the polymorphisms were associated with PGI/PGII. CONCLUSIONS Polymorphisms of HSP70 genes are associated with the development of gastric cancer and duodenal ulcers in a population at high risk for gastric cancer in Costa Rica.

Abstract
Tumor necrosis factor β (TNF-β) 252 A/G polymorphism has been implicated to be associated with risk of gastric cancer, but previous studies showed inconsistent and inconclusive results. Therefore, we performed a meta-analysis to assess the association between TNF-β 252 A/G polymorphism and gastric cancer risk. Relevant studies were searched from PubMed database. Odds ratios (OR) and 95% confidence intervals (95% CI) were calculated to evaluate the strength of the associations between TNF-β 252 A/G polymorphism and gastric cancer risk. Overall, 11 individual case-control studies with 2,270 cases and 4,404 controls were included in the final meta-analysis. Meta-analysis of total 11 studies showed that TNF-β 252 A/G polymorphism was associated with the risk of gastric cancer (G vs. A: OR = 1.10, 95% CI 1.02-1.19, P = 0.015; GG/AG vs. AA: OR = 1.21, 95% CI 1.00-1.47, P = 0.049). Subgroup analysis by ethnicity showed that TNF-β 252 A/G polymorphism was only associated with the risk of gastric cancer in Asians, but not Caucasians. The findings from the current meta-analysis suggest that TNF-β 252 A/G polymorphism is associated with the risk of gastric cancer, especially in Asians.

Abstract
BACKGROUND In Mexico, the initial severe cases of the 2009 influenza pandemic virus A (H1N1) [A(H1N1)pdm09] were detected in early March. The immune mechanisms associated with the severe pneumonia caused by infection with this new virus have not been completely elucidated. Polymorphisms in interleukin genes have previously been associated with susceptibility to infectious diseases due to their influence on cytokine production. OBJECTIVES The present case-control study was performed to compare several immunologic and genetic parameters of patients and controls during the initial phase of the pandemic. STUDY DESIGN Sixty-five patients who were hospitalized due to infection with the influenza A(H1N1)pdm09 virus and 46 healthy controls were studied. A hemagglutination inhibition assay (HIA) was performed to measure anti-influenza antibody titers in these subjects. Protein levels of the cytokines interleukin (IL)-4, IL-6, IL-8, IL-10, tumor necrosis factor-α (TNFα), interferon gamma (IFNγ), transforming growth factor beta (TGFβ)1 and TGFβ2 were quantified in plasma. Single nucleotide polymorphisms in IL6, IL10 and TNFα were also assessed. RESULTS Influenza patients had lower antibody titers and produced significantly higher levels of IL-6, IL-10 and TNFα than healthy controls. The frequencies of the TNFα -308G, IL-10 -592C and IL-10 -1082A alleles and the IL10 -1082(A/A) genotype were associated with susceptibility to severe disease, while the haplotypes TNFα AG and IL-10 GTA and GCA were associated with protection from severe disease [P=0.016, OR (CI)=0.11 (0.01-0.96); P=0.0187, OR (CI)=0.34 (0.13-0.85); P=0.013, OR (CI)=0.39 (0.18-0.83)]. CONCLUSIONS This study demonstrates that the influenza A(H1N1)pdm09 patients and healthy controls have different profiles of immune parameters and that there is an association between IL-10 and TNFα polymorphisms and the outcome of this disease.

Abstract
BACKGROUND Epidemiological studies have evaluated the association between tumor necrosis factor α (TNF-α) single nucleotide polymorphisms (SNPs) and duodenal ulcer (DU), but the results remain inconclusive. The aim of this study was to perform a meta-analysis to investigate a more authentic association between TNF-α SNPs and DU. METHODS We performed the meta-analysis by searching PubMed, Embase, and Web of Science databases from the first available year to Sep. 5, 2012. Additionally, checking reference lists from identified articles, reviews, and the abstracts presented at related scientific societies meetings were also performed. All case-control studies investigating the association between TNF-α SNPs and DU risk were included. The association was assessed by odds ratio (OR) with 95% confidence interval (CI). Publication bias was analyzed by Begg's funnel plot and Egger's regression test. RESULTS A total of sixteen studies reporting TNF-α -308G/A, -1031T/C, -863C/A, -857C/T, and -238G/A polymorphism were included in our final meta-analysis. There was no statistically significant association between -308G/A polymorphism and DU in the overall study population, as well as subgroup analyses by ethnicity, study design, and H. pylori status. As for -1031T/C, -863C/A, -857C/T, and -238G/A, results of our meta-analyses showed no statistical evidence of significant association. Power calculation on the combined sample size showed that the statistical powers were all lower than 80% for all the meta-analyses. CONCLUSIONS The data suggests that there is no statistical evidence of significant association between the studied TNF-α SNPs and DU. However, this conclusion should be interpreted with caution as low statistical powers were revealed by power calculations. In future, larger sample-size studies with homogeneous DU patients and well-matched controls are required.

Abstract
BACKGROUND Tumor necrosis factor-α (TNF-α) plays a crucial role in the development and progression of gastric cancer. A functional polymorphism, -308 G>A (rs1800629), which is located in the promoter of TNFA gene, has been suggested to alter the production of TNF-α and influence cancer risk. In the present study, we sought to investigate whether this polymorphism has effects on the risk and progression of gastric cancer in a Chinese population. METHODS We genotyped the TNFA -308 G>A polymorphism using the TaqMan method in a two-stage case-control study comprising a total of 1686 gastric cancer patients and 1895 cancer-free subjects. The logistic regression was used to assess the genetic associations with occurrence and progression of gastric cancer. RESULTS We found a significant association between the variant genotypes and increased risk of gastric cancer [P = 0.034, odds ratio (OR) = 1.39, 95% confidence interval (CI) = 1.01-1.67, GA/AA vs. GG]. Similar results were observed in the follow-up replication study. When combined the data from the two studies, we found a more significant association (P = 0.001, OR = 1.34, 95%CI = 1.13-1.59), especially for older subjects (>65 years). Furthermore, the patients carrying the variant genotypes had a significantly greater prevalence of T4 stage of disease (P = 0.001, OR = 2.19, 95%CI = 1.39-3.47) and distant metastasis (P = 0.013, OR = 1.61, 95%CI = 1.10-2.35). CONCLUSIONS Our results suggest that the functional promoter -308 G>A polymorphism in TNFA influence the susceptibility and progression of gastric cancer in the Chinese population.

Abstract
BACKGROUND/AIM Gastric cancer (GC) is the fourth most common cancer and the second most common cause of cancer death world-wide after lung cancer. It is a multifactorial disease with the involvement of both genetic and environmental risk factors. Genetic variation in genes encoding cytokines and their receptors, determine the intensity of the inflammatory response, which may contribute to individual differences in severity of outcome of the disease. Tumor necrosis factor alpha (TNF-α) is a potent pro-inflammatory cytokine and acid inhibitor. A bi allelic G to A polymorphism at -308 upstream from the transcription initiation site of the promoter is associated with elevated TNF levels. The present study is aimed at evaluating the role of TNF-α-308 (G → A) gene polymorphism and susceptibility to GC. SUBJECTS AND METHODS A case-control study was carried out in 114 GC patients and 229 healthy control subjects. TNF-α genotyping at position-308 (G → A) was carried out by amplification refractory mutation system-polymerase chain reaction (ARMS-PCR) method followed by agarose gel electrophoresis. RESULTS The distribution of TNF-α genotypes at -308 (G → A) were GG 28.07%, GA 66.67% and AA 5.26% in GC patients and GG 33.19%, GA 55.89% and AA 10.92% in control subjects. The frequencies of alleles G and A were 0.614 and 0.386 in GC patients and 0.611 and 0.389 in control subjects respectively. CONCLUSION The study showed no significant difference in the distribution of genotype and allelic frequencies between GC patients and control subject.

Abstract
OBJECTIVE Esophageal cancer development is a sequence that starts with reflux esophagitis (RE), followed by Barrett's esophagitis (BE), dysplasia, and finally esophageal adenocarcinoma (EAC). Tumor necrosis factor (TNF) is a potent anti-neoplastic agent, hence DNA polymorphisms that reduce TNF levels potentially enhance the development of BE and EAC. The aim of the study was to determine the impact of TNF gene variation on the RE-BE-EAC cascade. METHODS DNA from 887 Caucasian participants (197 controls, 305 RE, 257 BE, 128 EAC) was tested for the gene polymorphism TNF-β NcoI, and TNF production was determined by TNF-α specific immunohistochemistry on esophageal biopsies from these BE (n = 31) and EAC (n = 4) patients. RESULTS As compared with healthy controls, the TNF-β NcoI A/A genotype was significantly more prevalent in BE (p = 0.04) and EAC patients (p = 0.02), but not in RE patients (p = 0.1). While TNF-α protein levels were invariably high in esophageal biopsies from EAC patients, most esophageal BE samples showed low to moderate TNF levels. CONCLUSIONS Chronic inflammation, like in BE, markedly increase the risk of malignant transformation. In this study, the significantly higher frequency of the TNF-β NcoI A/A genotype and the local TNF expression indicate that the pro-inflammatory cytokine TNF plays a role in the development of BE and EAC.

Abstract
Lymphotoxin-α (LT-α) and interleukin-1beta (IL-1β) are proinflammatory cytokines playing important roles in immunity against Leishmania infection and the outcome of the disease. As cytokine productions are under the genetic control, this study tried to find any probable relationship between these cytokine gene polymorphisms and the susceptibility to visceral leishmaniasis in Iranian pediatric patients. Ninety-five pediatric patients involved with visceral leishmaniasis and 128 non-relative healthy people, from the same area as the patients, were genotyped for LT-α (+252A/G) and IL-1β (+3953T/C and -511T/C) gene polymorphisms using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). There was not found any significant differences in allele and genotype frequencies of LT-α (+252A/G) and IL-1β (+3953) among the study groups. However, the frequency of IL-1β -511TT genotype was higher in the controls (P = 0.0004) while the frequency of IL-1β -511CC genotype and C allele were higher in the patients (P = 0.008 and P = 0.00006, respectively). Furthermore, IL-1β CC (-511/+3953) haplotype was more frequent in VL patients compared with the controls (P = 0.0002) and the distribution of TT haplotype was higher in the controls compared with the patients (P = 0.003). In conclusion, based on the results, IL-1β -511C allele, CC genotype and CC (-511/+3953) haplotype could be considered as the susceptibility factors for visceral leishmaniasis while IL-1β -511TT genotype, T allele and TT haplotype (-511/+3953) might be counted as the influential factors for resistance to the disease.

Abstract
To evaluate the association between gastric cancer susceptibility and inflammation-related gene polymorphisms, the authors conducted a series of meta-analyses using a predefined protocol. Genes investigated were those coding for the interleukin (IL) proteins (IL1B, IL1RN, IL8, and IL10) and for tumor necrosis factor-alpha. Gastric cancers were stratified by histologic subtype and anatomic subsite, by Helicobacter pylori infection status, by geographic location (Asian or non-Asian study population), and by a quantitative index of study quality. All published literature and meeting abstracts from the period 1990-2006 were considered. Results consistently supported increased cancer risk for IL1RN2 carriers; the increased risk was specific to non-Asian populations and was seen for intestinal and diffuse cancers, distal cancers, and, to a lesser extent, cardia cancers. Analyses restricted to high-quality studies or H. pylori-positive cases and controls also showed significant associations with both carrier status and homozygosity status. In Asian populations, reduced risk was observed in association with IL1B-31C carrier status. This effect was also observed in analyses restricted to high-quality studies. These results indicate the importance of stratification by anatomic site, histologic type, H. pylori infection, and country of origin. Study quality considerations, both laboratory and epidemiologic, can also affect results and may explain, in part, the variability in results published to date.

Abstract
Tumour Necrosis Factor (TNF) and Heat Shock Protein 70 (HSP70) are important molecules in inflammatory, infectious and tumoral processes. The genes codifying these molecules are polymorphic and certain alleles have been associated with susceptibility to disease. Gastric cancer is associated with an Helicobacter pylori-induced chronic inflammatory response. The aim of this work was to analyze whether polymorphisms in inflammation-related genes are associated with the development of gastric cancer. We studied 447 Mexican adult patients including 228 with non-atrophic gastritis, 98 with intestinal metaplasia, 63 with gastric cancer and 58 with duodenal ulcer, and 132 asymptomatic individuals as well. DNA from peripheral white blood cells was typed for the Single Nucleotide Polymorphisms (SNPs) -308 of TNF-alpha, +252 of TNF-beta, +190 of HSP70-1, +1267 of HSP70-2 and +2437 of HSP70-HOM. Compared with the asymptomatic group, we found a significant association of TNF-beta*A and HSP70-1*C alleles with gastric cancer (OR 5.69 and 3.76, respectively) and HSP70-1*C with duodenal ulcer (OR 3.08). Genotype TNF-beta G/G showed a significant gene-dose effect with gastric cancer (OR 0.09); whereas HSP70-1 C/G showed significant association with both, gastric cancer (OR 13.31) and duodenal ulcer (OR 16.19). Polymorphisms in TNF and HSP70 showed a significant severity-dose-response as risk markers from preneoplastic lesions to gastric cancer in Mexican population, probably because of their association with an intense and sustained inflammatory response.

Abstract
The incidence of stomach cancer is high in certain parts of the world, particularly in China. Chronic Helicobacter pylori infection is the main risk factor, yet the vast majority of infected individuals remain unaffected with cancer, suggesting an important role of other risk factors. We conducted a population-based case-control study including 196 incident stomach cancer cases and 397 matched controls to test the hypothesis that adverse single nucleotide polymorphism (SNP) genotypes and haplotypes within genes of the DNA repair and immune regulatory pathways are associated with increased stomach cancer risk. Genomic DNA isolated from blood samples was used for genotyping, and results were obtained for 57 putatively functional SNPs in 28 genes. Odds ratios (OR) and 95% confidence intervals (95% CI) were obtained from adjusted logistic regression models. For PTGS2, a gene involved in the inflammatory response, associations with stomach cancer risk were observed for TC genotype carriers of rs5279 (OR, 0.24; 95% CI, 0.08-0.73), CT genotype carriers of the 3'-untranslated region SNP rs689470 (OR, 7.49; 95% CI, 1.21-46.20), and CTTC haplotype carriers of rs5277, rs5278, rs5279, and rs689470 (OR, 0.41; 95% CI, 0.18-0.95). For ERCC5, a gene involved in nucleotide excision repair, TC genotype carriers of rs1047768 (OR, 0.65; 95% CI, 0.41-1.03), GC genotype carriers of the nonsynonymous SNP rs2227869 (OR, 0.30; 95% CI, 0.13-0.67), and CCG haplotype carriers of rs1047768, rs17655, and rs2227869 (OR, 0.45; 95% CI, 0.20-1.04) were associated with reduced stomach cancer risk. In conclusion, PTGS2 and ERCC5 were associated with stomach cancer risk in a Chinese population.

Abstract
BACKGROUND The present study epidemiologically clarified the different roles of Helicobacter pylori (Hp) infection in carcinogenesis between two major histological types of noncardia gastric cancer (ncGC), intestinal (=differentiated) and diffuse (=undifferentiated), by analyzing IgG antibody titer against Hp surface antigen on the data set of a nested case-control study in a large cohort study conducted in Japan. METHODS A total of 36,745 subjects aged 40 to 69 years in the Japan Health Center-based prospective study who responded to the baseline questionnaire and provided blood were followed over 15 years; 350 ncGC cases (differentiated=242, undifferentiated=108) matched to controls were used. Using baseline blood samples, plasma IgG titer was measured using ELISA. The level of IgG titer >10 U (cut-off value) was classified into three grades in groups of equal number: low, middle, and high. RESULTS IgG titer of Hp was significantly (p<0.01) higher in undifferentiated cases than in differentiated ones. Among the three grades of Hp IgG titer, the high titer was more closely associated with risk of undifferentiated ncGC (odds ratio (OR) for high=7.8, 95% confidence interval (CI)=2.4-24.9 vs. OR for low=6.4, 95% CI=2.1-19.6), while the low titer was a better predictor of differentiated ncGC (OR for high=3.2, 95% CI=1.6-6.4 vs. OR for low=5.9, 95% CI=3.0-11.6, trend p < 0.05). The high titer group had the lowest risk to develop differentiated ncGC with <7 years (OR=3.2, 95% CI=1.3-7.7), whereas the high titer group demonstrated the highest risk for undifferentiated ncGC developing (OR=11.6 95% CI=2.3-59.1). CONCLUSION Our study epidemiologically confirmed that atrophic changes caused by Hp infection determine the development of differentiated-type ncGC, and the inflammation itself induced by Hp infection promotes the development of undifferentiated-type ncGC.

Abstract
OBJECTIVES The relationship between Helicobacter pylori status and host tumor necrosis factor alpha (TNF-alpha) promoter susceptibility in ulcers inautoimmune pancreatitis (AIP) is unknown. We sought to study the frequency of peptic ulcer, the association of peptic ulcer with H. pylori and host TNF-alpha promoter haplotype in AIP and nonautoimmune chronic pancreatitis. METHODS Esophagogastroduodenoscopy (EGD) was performed in 40 patients with AIP and 113 patients with nonautoimmune chronic pancreatitis (CP). The status of H. pylori infection was determined. Genotyping and 5-locus haplotype assembly of the TNF-alpha promoter were performed. The correlation between clinical characteristics, endoscopic findings, Helicobacter pylori infection status, and TNF-alpha promoter polymorphism and haplotype was analyzed. RESULTS The frequencies of gastric ulcer (GU) was higher in patients with AIP compared with patients with nonautoimmune CP (22.5% vs 4.4%, P = 0.001). Duodenal ulcer (DU) was more prevalent than GU in both patients with AIP and patients with nonautoimmune CP. There was no difference in the positive status of H. pylori and TNF-alpha promoter polymorphism/haplotype. CONCLUSIONS Our results demonstrated that GU was more prevalent in AIP compared with nonautoimmune CP. Positive H. pylori status and host TNF-alpha promoter susceptibility could not explain the pathogenesis of higher GU prevalence and pathogenesis of AIP in our population.

Abstract
Development of gastric cancer is a multistage, multifactorial process. This study determined the population attributable risk for environmental and genetic risk factors in development of gastric cancer. A 1:1 cancer case-control study was undertaken in Nanjing, Jiangsu Province, China. A conditional-logistic regression model was used to determine environmental and genetic risk factors and calculate attributable risk (AR%) for each environmental and genetic risk factor in gastric cancer. In addition, the summary attributable risk (sAR) for all of the risk factors among 503 cases of gastric cancer patients and controls was determined. The environmental risk factors for gastric cancer in the Nanjing area were family history of tumor, consumption of pickled food, engorgement after hunger, irregular dietary habits, and lack of fruit intake. The genetic risk factors included the following genotypes: CYP2E1 wild, NAT2 M1 mutation, NAT2 slow-acetylators, XRCC1 194 mutation, MTHFR A1298C mutation, and IL-1B mutation. Combining environmental and genetic risk factors, sAR was 76.34%. Data suggest that genetic polymorphisms and environmental risk factors play concurrent roles in the development of gastric cancer. The results of this study indicate preventive strategies to avoid development of gastric cancer based on identified genetic polymorphisms and control of environmental risk factors.

Abstract
Given the fact that infectious agents contribute to around 18% of human cancers worldwide, it would seem prudent to explore their role in neoplasms of the ocular adnexa: primary malignancies of the conjunctiva, lacrimal glands, eyelids, and orbit. By elucidating the mechanisms by which infectious agents contribute to oncogenesis, the management, treatment, and prevention of these neoplasms may one day parallel what is already in place for cancers such as cervical cancer, hepatocellular carcinoma, gastric mucosa-associated lymphoid tissue lymphoma and gastric adenocarcinoma. Antibiotic treatment and vaccines against infectious agents may herald a future with a curtailed role for traditional therapies of surgery, radiation, and chemotherapy. Unlike other malignancies for which large epidemiological studies are available, analyzing ocular adnexal neoplasms is challenging as they are relatively rare. Additionally, putative infectious agents seemingly display an immense geographic variation that has led to much debate regarding the relative importance of one organism versus another. This review discusses the pathogenetic role of several microorganisms in different ocular adnexal malignancies, including human papilloma virus in conjunctival papilloma and squamous cell carcinoma, human immunodeficiency virus in conjunctival squamous carcinoma, Kaposi sarcoma-associated herpes virus or human herpes simplex virus-8 (KSHV/HHV-8) in conjunctival Kaposi sarcoma, Helicobacter pylori (H. pylori,), Chlamydia, and hepatitis C virus in ocular adnexal mucosa-associated lymphoid tissue lymphomas. Unlike cervical cancer where a single infectious agent, human papilloma virus, is found in greater than 99% of lesions, multiple organisms may play a role in the etiology of certain ocular adnexal neoplasms by acting through similar mechanisms of oncogenesis, including chronic antigenic stimulation and the action of infectious oncogenes. However, similar to other human malignancies, ultimately the role of infectious agents in ocular adnexal neoplasms is most likely as a cofactor to genetic and environmental risk factors.

Abstract
We conducted a meta-analysis to assess the association between tumor necrosis factor-alpha (TNF-alpha) gene TNFA-308 (G > A) and TNFA-857 (C > T) polymorphisms and gastric cancer (GC) susceptibility. We also performed subgroup analyses based on ethnicity (Caucasian, east Asian, and other populations) and tumor location [noncardia gastric cancer (NCGC)]. There were 3,335 GC patients and 5,286 controls for TNFA-308, and 1,118 GC patients and 1,591 controls for TNFA-857 in our analysis. Overall, allele contrast (A vs. G) of TNFA-308 polymorphism produced significant results in worldwide populations [Pheterogeneity = 0.05, random-effects (RE) odds ratio (OR) 1.19; 95% confidence interval (CI) 1.03-1.37, P = 0.02] and Caucasian populations (Pheterogeneity = 0.15, fixed-effects (FE), OR 1.27; 95% CI 1.11-1.45, P = 0.0005). Similar results were also obtained in recessive models and homozygote contrasts. No significant association was observed in NCGC and east Asian subgroup analysis. T variant of TNFA-857 produced significant results only in allele contrast (Pheterogeneity = 0.38, FE OR 1.17; 95% CI 1.01-1.35, P = 0.04). In conclusion, TNFA-308 locus of TNF-alpha would be a risk factor for GC, especially in Caucasian populations. Besides, TNFA-857 locus may be related to GC risk, which demonstrated changeability of results in different contrasts.

Abstract
Inflammation is one of the early phases in the development of gastric cancer. Therefore, several studies have examined the association of polymorphisms in tumour-necrosis factor-A gene (TNF-A) with gastric cancer risk. This meta-analysis reviews and summarises published evidence for these associations. Searching several databases yielded 24 independent studies that reported on the associations between TNF-A polymorphisms and gastric cancer risk. We analysed available data for the most commonly investigated polymorphisms: TNF-A –308G>A (23 studies), TNF-A –238G>A (9 studies), and TNF-A –857C>T (5 studies). Summary odds ratios (ORs) and 95% confidence intervals (95% CIs) were calculated in the random-effects model using the DerSimonian–Laird method. Q-statistic and I2-statistic were calculated to examine heterogeneity, and funnel plots were plotted to examine small study effects. The overall ORs (95% CIs) for AG and AA genotypes vs GG genotype for TNF-A –308 were 1.09 (0.94–1.27) and 1.49 (1.11–1.99), respectively. For TNF-A –238, the corresponding ORs (95% CIs) were 1.05 (0.84–1.33) and 1.25 (0.30–5.26), respectively. The overall ORs (95% CIs) for CT and TT genotypes (vs CC) for TNF-A –857 were 1.06 (0.89–1.27) and 1.57 (0.91–2.70), respectively. The statistically significant association between TNF-A –308GG and gastric cancer was limited to western populations. This association showed little heterogeneity (I2=0) and remained consistently strong when analyses were limited to anatomic and histologic subtypes of gastric cancer, or limited to studies in which genotype frequencies were in Hardy–Weinberg equilibrium, or limited to larger studies. These same subgroup analyses did not change results associated with other polymorphisms. In conclusion, TNF-A –308AA genotype was associated with a statistically significant increased risk of gastric cancer, whereas other studied polymorphisms were not. The association between TNF-A –857TT genotype and gastric cancer was near significant, and may become significant if more studies are published.

Abstract
Helicobacter pylori (H. pylori) causes gastritis, development of lymphoid follicles and later monoclonal mucosa-associated lymphoid tissue (MALT) lymphoma. We evaluated the association of tumor necrosis factor (TNF)-alpha (-308 G/A) and IL-10 (-819 C/T) gene polymorphisms with gastritis and lymphoid follicle formation. H. pylori infection was detected using modified Giemsa staining and IgG anti-CagA enzyme-linked immunosorbent assay (ELISA). One hundred and thirty patients with non-ulcer dyspepsia (NUD) and 200 healthy age-matched controls were genotyped for TNF-alpha and IL-10 polymorphisms using polymerase chain reaction-restriction fragment-length polymorphism (PCR-RFLP). Subjects with IL-10 -819 T allele [patients (46.5%) versus controls (35.7%), p = 0.006, OR = 1.56, 95% CI = 1.14-2.15] were at risk of gastritis. Infection with H. pylori was more often associated with lymphoid follicles formation than its absence (46% versus 22%, p = 0.009). TNF-alpha polymorphism did not influence gastritis but patients with TNF-alpha -308 A allele carriers showed >2 fold risk of lymphoid follicle formation [presence (26%) versus absence (11.25%), p = 0.029, OR = 2.8; 95% CI = 1.09-7.08]. There was a trend towards association of lymphoid follicles and TNF-alpha -308 A allele carriers with H. pylori infection than without (58.5% versus 22.2%; p = 0.064). IL-10 -819 T and TNF-alpha -308 A alleles may increase risk of gastritis and lymphoid follicle formation.

Abstract
BACKGROUND AND AIM Helicobacter pylori is a major cause of chronic gastritis and peptic ulcer disease and a definite carcinogen for gastric adenocarcinoma. However, the underlying pathogenic mechanisms are not fully understood. Interleukin-1 (IL-1) is a key cytokine involved in H. pylori-induced gastric inflammation. The present study aimed to determine polymorphisms of IL-1B and IL-1 receptor antagonist (IL-1RN) genes and their association with H. pylori infection and gastroduodenal diseases in Chinese patients. METHODS Three hundred and ninety-nine patients with gastroduodenal diseases (129 chronic gastritis, 127 duodenal ulcer and 143 non-cardiac gastric cancer) and 264 healthy controls were genotyped for IL-1B-511 and IL-1RN gene polymorphisms by the PCR-RFLP method. H. pylori infection status was determined by a validated serological test. RESULTS The frequency of IL-1B-511 T allele was significantly higher in H. pylori positive patients with non-cardiac gastric cancer than in both H. pylori negative patients with non-cardiac gastric cancer (60%vs 46%, P = 0.0342, OR = 1.666, 95% confidence interval [CI]: 1.045-2.656) and in healthy controls (60%vs 48%, P = 0.0071, OR = 1.665, 95%CI: 1.149-2.412). However, the polymorphism was not associated with chronic gastritis and duodenal ulcer. Multivariate logistic regression analyses identified that IL-1B-511 T/T carrier status was an independent risk factor for non-cardiac gastric cancer in the presence of H. pylori infection (adjusted OR = 3.01, 95%CI: 1.27-7.11, P = 0.01), and the frequency of IL-1B-511 T allele was an increased risk factor for developing gastric cancer (P = 0.03, adjusted OR = 2.29, 95%CI: 1.08-4.86). There was no association between IL-1RN gene polymorphisms and H. pylori infection and other gastroduodenal diseases. CONCLUSION IL-1B-511 T allele is associated with H. pylori infection in non-cardiac gastric cancer in a Chinese population. The IL-1B-511 gene polymorphism appears to play an important role in gastric carcinogenesis in Chinese patients with H. pylori infection.

Abstract
SUMMARY
Helicobacter pylori
is the first formally recognized bacterial carcinogen and is one of the most successful human pathogens, as over half of the world's population is colonized with this gram-negative bacterium. Unless treated, colonization usually persists lifelong.
H. pylori
infection represents a key factor in the etiology of various gastrointestinal diseases, ranging from chronic active gastritis without clinical symptoms to peptic ulceration, gastric adenocarcinoma, and gastric mucosa-associated lymphoid tissue lymphoma. Disease outcome is the result of the complex interplay between the host and the bacterium. Host immune gene polymorphisms and gastric acid secretion largely determine the bacterium's ability to colonize a specific gastric niche. Bacterial virulence factors such as the cytotoxin-associated gene pathogenicity island-encoded protein CagA and the vacuolating cytotoxin VacA aid in this colonization of the gastric mucosa and subsequently seem to modulate the host's immune system. This review focuses on the microbiological, clinical, immunological, and biochemical aspects of the pathogenesis of

Abstract
OBJECTIVE To evaluate whether or not genetic polymorphism of IL-1B, IL-1RN, and TNF-Alpha is an important factor in the different expression of gastroduodenal diseases after Helicobacter pylori infection. METHODS This study consisted of 1360 subjects: control, gastric cancer (GC, intestinal type, and diffuse type), benign gastric ulcer (BGU), duodenal ulcer, and first-degree gastric cancer relative (GCR). IL-1Beta-511 and TNF-A-308 biallelic polymorphism were genotyped by 5' nuclease polymerase chain reaction (PCR) assays, and PCR-restriction fragment length polymorphism (PCR-RFLP). IL-1RN penta-allelic variable number of tandem repeats was genotyped by PCR. RESULTS There was no difference in the genetic polymorphism of IL-1Beta-511, IL-1RN and TNF-A in the patients with gastric cancer regardless of H. pylori positivity compared with control. However, the frequencies of IL-1B-511 C/T (OR: 0.5, 95% CI: 0.3-0.7) and T carrier (OR: 0.6, 95% CI: 0.4-0.8) were lower in the H. pylori-positive BGU patients. The IL-1RN 2/2 was higher (OR: 5.5, 95% CI: 1.1-28.5) in the H. pylori-positive GCR. There was no significance in the polymorphism of TNF-Alpha-308 regardless of H. pylori-induced gastroduodenal diseases. CONCLUSIONS The IL-1Beta-511 T-carrier polymorphism has a negative effect on the development of H. pylori-positive BGU, and high frequency of IL-1RN 2/2 was found in the H. pylori-positive relatives of GC patients, which suggest that this genetic polymorphism could play some role in the H. pylori-induced gastroduodenal diseases in Korea.
