RAS patients with H. pylori gastritis showed a higher frequency (51.9%) of GC IL-6 genotype than RAS patients without H. pylori gastritis (11.1%) (p=0.036).
In conclusion, an IL-1β+3954C/T polymorphism was determined to be related to susceptibility to RAS, and individuals with the G allele and GG genotype of IL-6-174 or the A allele of IL-10-592 or the G allele of IL-10-1082 appeared to be more vulnerable to developing RAS.
An odds ratio (OR) with a 95% confidence interval (CI) was applied to assess the association of the IL-6-174 G/C and IL10-1082 G/A polymorphisms with RAS susceptibility.
The purpose of the present study was to investigate, using binary logistic regression analyses, a possible association between the functional IL-1beta +3954 (C/T), IL-6 -174 (G/C), IL-10 -1082 (G/A) and TNF-alpha -308 (G/A) genetic polymorphism and RAS in a sample of Brazilian patients, using a multivariate statistical analysis.
In conclusion, IL-1 and IL-6 or its receptor gene variants cannot be used as markers for identification of Czech patients with increased risk of recurrent aphthous stomatitis.
The purpose of the present study was to investigate if the IL-6 gene polymorphisms are associated with RAS or clinical characteristics of RAS in a cohort of Turkish population.
A meta-analysis was conducted using Revman 5.3 software (London, UK), and the pooled odds ratio (OR) and 95% confidence interval (CI) were then used to evaluate the strength of the relationship between the gene polymorphisms of IL-1beta(-511C/T), IL-1beta(+3954C/T), IL-6(-174G/C) and IL-10(-1082G/A) and the risk of RAS.
The overall analysis proved that the IL10-1082 G/A polymorphism was significantly associated with the risk of RAS in a dominant model (GG + AG vs AA: OR = 1.49, 95% CI = 1.10-2.01, P = .01).
The purpose of the present study was to investigate, using binary logistic regression analyses, a possible association between the functional IL-1beta +3954 (C/T), IL-6 -174 (G/C), IL-10 -1082 (G/A) and TNF-alpha -308 (G/A) genetic polymorphism and RAS in a sample of Brazilian patients, using a multivariate statistical analysis.
The meta-analysis suggested that the mutation of IL-1beta(-511C/T) in Europe and IL-1beta(+3954C/T) in America tend to increase the risk of RAS, but the polymorphism of IL-10(-1082G/A) appears to have no association with RAS risk in America.
In conclusion, an IL-1β+3954C/T polymorphism was determined to be related to susceptibility to RAS, and individuals with the G allele and GG genotype of IL-6-174 or the A allele of IL-10-592 or the G allele of IL-10-1082 appeared to be more vulnerable to developing RAS.
In Asian populations, the IL-10-1082 G/A polymorphism was associated with a protective effect for RAS using the allelic, additive, and recessive models.
While a significant negative association was found between the C allele at the same position with RAS (P = 0.003), the TT genotype was significantly more frequent at position rs3806265 in NLRP3 in patient group than in the controls (P = 0.002).
In respect of HLA genes, factors are involved in the incidence of RAS; various HLA-DRB and HLA-DQB1 alleles and the related haplotypes are suggested to be the three main RAS susceptibility factors in our population study.
In conclusion, IL-1 and IL-6 or its receptor gene variants cannot be used as markers for identification of Czech patients with increased risk of recurrent aphthous stomatitis.
In conclusion, an IL-1β+3954C/T polymorphism was determined to be related to susceptibility to RAS, and individuals with the G allele and GG genotype of IL-6-174 or the A allele of IL-10-592 or the G allele of IL-10-1082 appeared to be more vulnerable to developing RAS.
Thirty-six patients with RAS and 130 patients without RAS were genotyped for IL-1β (-511C/T) and IL-6 (-174G/C) and evaluated for H. pylori infection and serum cobalamin level.
