The association of Toll-like receptor 9 (TLR9) gene polymorphisms with systemic lupus erythematosus (SLE) risk remains controversial and ambiguous. To more precisely estimate the relationship between TLR9 gene polymorphisms and the susceptibility to SLE, a metaanalysis was performed. A total of seven independent studies were involved in this analysis. Meta-analysis was performed for three TLR9 gene polymorphisms (rs187084, rs352139, and rs352140). We have compared allele or genotype frequencies of the polymorphisms in SLE patients and controls. When available studies were pooled into the meta-analysis, there was no evidence showing a significant association between rs187084 and SLE risk in an Asian population (for C vs. T: OR = 0.81, P = 0.117; for CC vs. TT: OR = 0.71, P = 0.158; for CT vs. TT: OR = 0.86, P = 0.085; for CC + CT vs. TT: OR = 0.78, P = 0.093; for CC vs. CT + TT: OR = 0.81, P = 0.285). Similar results were found between rs352139 and SLE. No significant association was detected in any genetic model in the Asian population either (for G vs. A: OR = 1.11, P = 0.095; for GG vs. AA: OR = 1.32, P = 0.238; for GA vs. AA: OR = 1.17, P = 0.084; for GG + GA vs. AA: OR = 1.17, P = 0.073; for GG vs. GA + AA: OR = 1.17, P = 0.404). We found no association between TLR9 gene rs352140 polymorphism and SLE in the Asian population (for A vs. G: OR = 1.02, P = 0.728). In conclusion, there is still not enough evidence to indicate an association between TLR9 gene rs187084, rs352139, and rs352140 polymorphisms and the development of SLE in the Asian population. © Japan College of Rheumatology 2012.

This study aims to derive a more precise estimation on carotid intima-media thickness (CIMT) level in patients with rheumatoid arthritis (RA) and related factors. Studies published from January 1, 1982 to December 31, 2014 in English, which comparing CIMT between RA group and control group were searched in PubMed, Embase, and Cochrane Library databases. Heterogeneity test was performed, and publication bias was evaluated. Stata software 12.0 was used to perform the meta-analysis. Two-thousand one hundred sixty-three articles were obtained after searching databases, and 47 studies were finally included in the meta-analysis. The result of the analysis in random effect model showed that RA group had significantly higher CIMT than control group, with the standardized mean difference (SMD) of 1.04 and 95% CI (0.81,1.27). To evaluate the stability of our results, sensitivity analyses were performed, and the results showed no significant change when any one study was excluded. Subgroup analyses showed that region, race, age, BMI, and disease duration were associated with CIMT in RA patients. In summary, CIMT in RA patients is thicker than healthy controls, and it is influenced by region, race, age, BMI, and disease duration. © 2015, International League of Associations for Rheumatology (ILAR).

The P2X7 receptor is a ligand-gated cationic channel receptor that is actived by ATP and normally expressed by a variety of immune system cells, including macrophages and lymphocytes. Because it leads to release of IL-1β and cell death by apoptosis or necrosis, it is a potential therapeutic target for a variety of autoimmune inflammatory diseases, such as systemic lupus erythematosus (SLE). The P2X7R gene is highly polymorphic, and many single-nucleotide polymorphisms (SNPs) have been detected. A case-control study was performed to investigate the associations of SNPs in the P2X7R gene (rs1718119, rs2230911 and rs3751143) with susceptibility to SLE in 535 Chinese SLE patients and 532 controls. Results showed that rs1718119 was associated with SLE; in particular carriers of the A allele and AA/AG/(AG+AA) genotypes were at lower risk of the disease [A versus G, P < 0.001, odds ratio (OR) = 0.543, 95% CI: 0.424-0.697; AG versus GG, P = 0.018, OR = 0.659, 95% CI: 0.466-0.931; AA versus GG, P = 0.011, OR = 0.176, 95% CI: 0.046-0.668; AG+AA versus GG, P = 0.004, OR = 0.607, 95% CI: 0.433-0.850], but no significant differences in rs2230911 and rs3751143 were observed between SLE patients and controls. Stratification of cases for the presence of nephritis showed that rs2230911 G allele and CG/(CG+GG) genotypes were at a lower risk of SLE with nephritis (LN) (G versus C, P = 0.011, OR = 0.640, 95% CI: 0.454-0.903; CG versus CC, P = 0.035, OR = 0.645, 95% CI: 0.429-0.970; GG versus CC, P = 0.101, OR = 0.349, 95% CI: 0.099-1.228; CG+GG versus CC, P = 0.015 OR = 0.612, 95% CI: 0.411-0.910), but rs1718119 and rs3751143 were not associated with LN. Analysis of the haplotypes revealed one haplotype (ACA) that appeared to be a significantly 'protective' haplotype (P = 0.009, OR = 0.708, 95% CI: 0.546-0.918) with SLE. The findings suggest that the P2X7R gene might contribute to SLE susceptibility in the Chinese population. © The Author 2013. Source

Abstract: Systemic lupus erythematosus (SLE) is a severe complex rheumatic disease, but good estimate of its prevalence and risk factors is lacking in China. The aim of the study was to explore the prevalence of SLE and risk factors in rural areas of Anhui Province of China. Eleven counties were randomly selected in Anhui Province, and then, 15 % of the villages in selected counties were randomly sampled as study sites. Patients with SLE were identified through two phases. Based on the cases identified, a population-based case-control study was designed to examine risk factors associated with SLE. A total of 1,253,832 individuals and identified 471 SLE cases were surveyed. Crude and age-standardized prevalence were estimated at 37.56 and 36.03 per 100,000 persons, respectively. Gender difference in the prevalence of SLE was significant (P = 4.62 × 10-76), and the age-standardized prevalence was 6.17 for males and 67.78 for females per 100,000 persons. The distribution of SLE prevalence was significant by age group (P = 1.78 × 10-53), and the peak prevalence was observed at 40-50 years. Multiple environmental factors were associated with SLE, including birth conditions, sweet food, cooking oil, taste, fruit consumption, sunlight exposure, quality of sleep, physical activities, drinking water, residence, negative life events, hepatitis B vaccine, age of menarche, and age at birth of first child (P < 0.05). Our large population-based epidemiological survey estimated the prevalence of SLE at 37.56 per 100,000 persons. Multiple environmental factors were associated with the development of SLE. © 2013 Springer-Verlag Berlin Heidelberg. Source

Objective: FAS/FASL gene promoter polymorphisms have been repeatedly associated with gastric cancer risk, but findings are inconclusive across studies. To address a more precise estimation of the relationship, a meta-analysis was performed. Methods: Data were collected from the Pubmed, Medline and EMBASE databases, with the last report up to 1 December,2011. Crude ORs with 95% CIs were used to assess the strength of the association by (1) the additive, (2) the codominant, (3) the dominant, and (4) the recessive models. Results: A total of seven studies, including six studies on FAS -1377G>A polymorphism, five studies on FAS -670A>G polymorphism, and six studies on FASL -844T>C polymorphism, were identifiedin the current meta-analysis. Overall, an association of FAS -1377G>A (AA versus GG: OR = 1.313, 95% CI = 1.045-1.650, Ph = 0.347, I2 = 10.8) and FASL -844T>C (CC versus TT: OR = 1.352, 95% CI = 1.043-1.752, Ph = 0.461, I2 = 0.0) polymorphisms with gastric cancer was found in the codominant model. However, we did not detect any association between gastric cancer and the FAS -670A>G polymorphism. In the subgroup analysis by ethnicity, similar elevated risks were also observed in Asian population for FAS -1377G>A (AA versus GG: OR = 1.309, 95% CI = 1.041-1.646, Ph = 0.240, I2 = 27.3) and FASL -844T>C (CC versus TT: OR = 1.420, 95% CI = 1.081-1.865, Ph = 0.524, I2 = 0.0) polymorphisms. Conclusions: This meta-analysis indicated that FAS -1377G>A and FASL -844T>C polymorphisms might be associated with gastric cancer risk. Source
