    ABSTRACT: Objectives: The aims of this study were to measure the levels of interleukin (IL)-33 and ST2 and T-helper (Th)2-associated cytokines (IL-13, IL-4, IL-5) in patients with ankylosing spondylitis (AS), and examine the correlation of serum cytokine levels with disease activity and laboratory parameters. Method: Serum IL-33, IL-13, IL-4, and IL-5 levels were assessed by sandwich enzyme-linked immunosorbent assay (ELISA), and the mRNA levels of IL-33 and ST2 were quantified by real-time quantitative polymerase chain reaction (RT-qPCR), in 43 AS samples and compared with 27 age- and sex-matched healthy controls. Results: Serum IL-33, IL-13, and IL-4 levels were increased significantly in AS patients compared with controls (p < 0.01); moreover, serum IL-33 and IL-13 levels were significantly higher in patients with active AS than in those with inactive AS (p < 0.05). The serum levels of IL-5 showed no significant difference between AS patients and controls (p > 0.05). Serum IL-33 levels were positively correlated with both IL-13 (r = 0.306, p < 0.01) and IL-4 levels (r = 0.432, p < 0.01). The mRNA levels of IL-33 and ST2 were significantly different between AS patients and controls (p < 0.01) but not between active and inactive AS patients. Conclusions: Serum levels of IL-33 could partially reflect AS disease activity and indicate that IL-33/ST2 signalling plays an important role in the pathogenesis of AS.

    ABSTRACT: Single-nucleotide polymorphisms (SNPs) in the Fc gamma receptor IIB (FCGR2B) gene have recently been found to be associated with several human autoimmune diseases. We undertook the current study to investigate the influence of these polymorphisms on the risk of ankylosing spondylitis (AS). A total of 306 patients with AS from Anhui, China, fulfilling the modified New York Criteria, and 300 matched healthy controls were analysed. All subjects were genotyped for two SNPs (rs1050501, rs10917661) in the FCGR2B gene, and the SNaPshot Assay was used for genotyping. SNP rs10917661 was significantly associated with AS [C vs. T: odds ratio (OR) 1.723, 95% confidence interval (CI) 1.086-2.733, p = 0.020; genotype: p = 0.026] whereas no association was found for rs1050501. Furthermore, no haplotype was found to be associated with AS. These findings indicated that rs10917661 may be a novel SNP involved in AS genetic predisposition in the Han Chinese population.

    ABSTRACT: Up to now, many publications about the Chinese population have evaluated the correlation between interleukin-10 (IL-10) -1082 and -592 polymorphisms and persistent hepatitis B virus (HBV) infection. However, the results remain inconclusive. In order to resolve this conflict, a meta-analysis was performed. Seven studies were included and dichotomous data are presented as the odds ratio (OR) with a 95% confidence interval (CI). The results of our study suggest that carriers of the IL-10 -592A allele were more likely to clear HBV spontaneously in the Chinese pooled population (A vs. C: OR = 0.799, 95% CI = 0.678-0.941, P = 0.007; AC vs. AA: OR = 1.343, 95% CI = 1.017-1.684, P = 0.011; AA vs. AC + CC: OR = 0.736, 95% CI = 0.594-0.912; AA + AC vs. CC: OR = 0.588, 95% CI = 0.408-0.848, P = 0.004) and the IL-10 -1082A allele was associated with significantly reduced persistent HBV infection risk in Chinese (A vs. G: OR = 0.701, 95% CI = 0.494-0.996, P = 0.047; AA vs. GG + GA: OR = 0.684, 95% CI = 0.476-0.982, P = 0.040). Persistent HBV infection susceptibility is associated with the gene polymorphism IL-10 -1082GA in the Chinese population and the clearance of HBV is associated with the gene polymorphism IL-10 -592CA in the Chinese population.

    ABSTRACT: The purpose of this study was to generate large-scale evidence on whether SUMO4 M55V polymorphism is associated with autoimmune and inflammatory diseases using a meta-analysis. We surveyed studies on the association of SUMO4 M55V polymorphism with autoimmune and inflammatory diseases in PubMed. Meta-analysis was performed for genotypes AG versus AA, GG versus AA, GG versus AA + AG, AG + GG versus AA and G allele versus A allele in a fixed/random effect model. We identified 16 studies (11, 407 cases and 10, 679 controls) using PubMed search. When all groups were pooled, we detected the association of SUMO4 M55V polymorphism with autoimmune and inflammatory diseases (G versus A: OR = 1.11, 95%CI = 1.03-1.19, P = 0.005; AG +GG versus AA: OR=1.17, 95%CI=1.06-1.28, P=0.001; GG versus AA+AG: OR=1.07, 95%CI=0.94-1.21, P=0.29; GG versus AA: OR=1.15, 95%CI=1.00-1.34, P=0.06; AG versus AA: OR=1.15, 95%CI=1.08-1.23, P<0.0001). In subgroup analyses, we detected the association of SUMO4 M55V polymorphism with autoimmune and inflammatory diseases in Asian population (G versus A: OR=1.18, 95%CI=1.08-1.28, P=0.0001; AG+GG versus AA: OR=1.30, 95%CI=1.16-1.45, P<0.00001; GG versus AA+AG: OR=1.04, 95%CI=0.78-1.37, P=0.80; GG versus AA: OR=1.20, 95%CI=0.99-1.45, P=0.07; AG versus AA: OR=1.32, 95%CI=1.18-1.49, P<0.00001). But the association was not found in Caucasian population. Meanwhile, an association of SUMO4 M55V polymorphism with autoimmune diabetes was found (G versus A: OR=1.18, 95%CI=1.08-1.30, P=0.0005; AG+GG versus AA: OR=1.22, 95%CI=1.13-1.32, P<0.00001; GG versus AA+AG: OR=1.15, 95%CI=0.96-1.38, P=0.13; GG versus AA: OR=1.32, 95%CI=1.08-1.60, P=0.006; AG versus AA: OR=1.23, 95%CI=1.13-1.33, P<0.00001). This meta-analysis demonstrates the association of SUMO4 M55V polymorphism with autoimmune and inflammatory diseases, especially in Asian population.
