Interleukin-16 rs4072111 Polymorphism is Associated with the Risk of Peri-Implantitis in the Chinese Population.

ABSTRACT:

Purpose

Peri-implantitis (PI) is a major contributor to dental implant failure. Genetic predisposition plays an essential role in the development of PI. The purpose of this study was to investigate the correlation of IL-16 gene single nucleotide polymorphisms (SNPs), rs11556218 and rs4072111, with PI at the gene level.

Patients and methods

A total of 162 patients with PI and 162 cases with healthy implants were recruited as the case and control groups, respectively. The genotypes were analysed using direct sequencing. The genotype and allele proportion between the case and control groups were compared using the chi-square test. The periodontal status of patients carrying different genotypes was analysed, including gingival index, plaque index, calculus index, peri-implant pocket depth (PPD), and clinical attachment level (CAL).

Results

The case and control groups were age- and gender-matched. In the case group, the rs4072111 CT genotype was majorly observed, and the T allele carriers showed a high PI risk. Patients with the rs4072111 CT genotype had worse periodontal status, which was reflected by the higher levels of the gingival index, plaque index, calculus index, PPD and CAL. The distribution of the rs11556218 genotype and T allele showed no significant difference between the case and control groups (P > 0.05).

Conclusion

The CT genotype of IL-16 gene rs4072111 SNP can be used as a factor assessing PI risk. Therefore, IL-16 genetic variation may be related to PI susceptibility in the Chinese Han population.

Osteoprotegerin Gene (OPG) Polymorphisms Associated with Peri-implantitis Susceptibility in a Chinese Han Population.

Project description:BACKGROUND The aim of this study was to investigate the association between T950C (rs2073617) and G1181C (rs2073618) polymorphisms of the osteoprotegerin gene (OPG) and the susceptibility of peri-implantitis in the Chinese Han population. MATERIAL AND METHODS 110 patients with peri-implantitis and 116 healthy persons from the Chinese Han population were included in this study using a case-control design; rs2073617 and rs2073618 in OPG were genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The linkage disequilibrium (LD) and haplotype analysis were performed with Haploview software. Hardy-Weinberg equilibrium (HWE) was assessed in the control group based on the genotype distributions of OPG polymorphisms. The genotype, allele, and haplotype distribution differences between the case and control groups were analyzed by chi-square test, and the relative risk of PD was expressed by odds ratio (OR) and 95% confidence interval (CI). RESULTS The study results showed that people carrying the CC genotype of rs2073618 were more likely to have peri-implantitis than GG genotype carriers (OR=2.18, 95% CI=1.03-4.62, p=0.04). In addition, patients with the C allele had 1.47 times the risk of suffering from peri-implantitis (OR=1.47, 95% CI=1.01-2.13, p=0.04), but not rs2073617 polymorphism. The G-C haplotype frequency of rs2073618-rs2073617 in OPG was significantly correlated to the increased susceptibility of peri-implantitis (OR=2.27, 95% CI=1.20-4.30). CONCLUSIONS OPG rs2073618 polymorphism may be related to the risk of peri-implantitis, but not rs2073617. Moreover, haplotype is also a non-ignorable risk factor.

Genetic association of the epidermal growth factor gene polymorphisms with peri-implantitis risk in Chinese population.

Project description:Peri-implant disease is an inflammatory disease and is related to genetic heterogeneity. Considering the genetic association of epidermal growth factor (EGF) gene polymorphisms with the susceptibility of periodontitis, its genetic association with peri-implantitis risk in a Chinese Han population was explored. Three hundred individuals who underwent dental implants were recruited, and divided into healthy implant group and peri-implantitis group. The genotype and allele distribution of EGF gene rs2237051 and rs4444903 polymorphisms were analyzed via direct sequencing and the frequencies were compared between the two groups using chi-square test. No significant difference was detected for the clinical information between healthy implant group and peri-implantitis group, including lifestyle habits platform type and position, peri-implant phenotype, brushing time, dental floss, and mouth washing frequencies. Individuals with peri-implantitis had poor periodontal status. The GG genotype and G allele of rs2237051 showed significant increasing trend in peri-implantitis group compared with the healthy implant group. Compared with the AA genotype carriers, rs2237051 GG genotype carriers showed lower risk to suffer from peri-implantitis (OR = 0.236, 95%CI = 0.089-0.624), and possessed low values of gingival index, plaque index and calculus index, peri-implant pocket depth (PPD) and clinical attachment level (CAL). But there was no significant difference for the rs4444903 genotype distributions between the case and control groups. In summary, EGF rs2237051 polymorphism showed close association with the genetic background of peri-implantitis. Rs2237051 GG genotype and G allele might be protective factors for the onset of peri-implantitis.

Interleukin-16 polymorphism is associated with an increased risk of ischemic stroke.

Project description:Clinical and experimental data have demonstrated that inflammation plays fundamental roles in the pathogenesis of ischemic stroke. Interleukin-16 (IL-16) is identified as a proinflammatory cytokine that is a key element in the ischemic cascade after cerebral ischemia. We aimed to examine the relationship between the IL-16 polymorphisms and the risk of ischemic stroke in a Chinese population. A total of 198 patients with ischemic stroke and 236 controls were genotyped using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and DNA sequencing method. We found that the rs11556218TG genotype and G allele of IL-16 were associated with significantly increased risks of ischemic stroke (TG versus TT, adjusted OR = 1.88; 95% CI, 1.15-3.07; G versus T, adjusted OR = 1.54; 95% CI, 1.05-2.27, resp.). However, there were no significant differences in the genotype and allele frequencies of IL-16 rs4778889 T/C and rs4072111 C/T polymorphisms between the two groups, even after stratification analyses by age, gender, and the presence or absence of hypertension, diabetes mellitus, hypercholesterolemia, and hypertriglyceridemia. These findings indicate that the IL-16 polymorphism may be related to the etiology of ischemic stroke in the Chinese population.

Chemokine Receptor 2 (CXCR2) Gene Polymorphisms and Their Association with the Risk of Developing Peri-Implantitis in Chinese Han Population.

Project description:PurposeThis study aimed to investigate the role of chemokine receptor 2 (CXCR2) gene polymorphisms in peri-implantitis susceptibility in a Chinese Han population.Patients and methodsA total of 260 individuals were included in this study, including 127 peri-implantitis patients and 133 healthy implants. CXCR2 gene rs2230054 and rs1126580 polymorphisms in different groups were analyzed by the Chi-square test. The odds ratios (ORs) and 95% confidence intervals (95% CIs) were employed to evaluate the association between CXCR2 polymorphism and peri-implantitis susceptibility.ResultsThe CT genotype of rs2230054 and the AG genotype and G allele of rs1126580 significantly increased in peri-implantitis patients compared with healthy implants (P < 0.05). The CT genotype of rs2230054 (OR = 1.825, 95% CI = 1.028-3.239) and the AG genotype of rs1126580 (OR = 2.223, 95% CI 1.272-3.885) carriers had a high risk to infect with peri-implantitis. Additionally, these CXCR2 gene polymorphisms have been revealed to be associated with the periodontal status of peri-implantitis patients.ConclusionThe CXCR2 gene rs2230054 and rs1126580 polymorphisms were associated with the peri-implantitis susceptibility in the Chinese Han population. The CT genotype of rs2230054 and the AG genotype and G allele of rs1126580 serve as risk factors for the occurrence of peri-implantitis.

Interleukin-16 rs4778889 polymorphism contributes to the development of renal cell cancer in a Chinese population.

Project description:We conducted a case-control study to assess the role of IL-16 rs4778889, rs11556218 and rs8034928 polymorphisms in the development of RCC. This case-control study included 181 patients with RCC and 278 control patients. The genotyping of IL-16 rs4778889, rs11556218 and rs8034928 polymorphisms were performed using polymerase chain reaction (PCR) combined with restriction fragment length polymorphism analysis. By ?(2) test, we found that patients with RCC were more likely to suffer from hypertension (?(2) = 9.06, P = 0.003) and diabetes (?(2) = 7.91, P = 0.005). By unconditional logistic regression analysis, the CC genotype of rs4778889 was associated with an increased risk of RCC compared to TT genotype, and the adjusted OR (95% CI) was 3.58 (1.59-8.31). In dominant model and recessive model, we found the rs4778889 polymorphisms were associated with an elevated increased risk of RCC, and the adjusted ORs (95% CI) were 1.64 (1.10-2.43) and 3.07 (1.40-6.98), respectively. We found that rs4778889 polymorphism had interaction with hypertension (OR = 2.44, 95% CI = 1.01-6.00) and diabetes (OR = 6.91, 95% CI = 1.44-37.05) in the risk of RCC. In conclusion, the results of our study suggested an association between the IL-16 rs4778889 polymorphism and an elevated risk of RCC.

Salivary Microbial Dysbiosis Is Associated With Peri-Implantitis: A Case-Control Study in a Brazilian Population.

Project description:Background and objectivesThe aim of this study was to examine the salivary microbiome in healthy peri-implant sites and those with peri-implantitis.MethodsSaliva samples were collected from 21 participants with healthy peri-implant sites and 21 participants with peri-implantitis. The V4 hypervariable region of the 16S rRNA gene was sequenced using the Ion Torrent PGM System (Ion 318™ Chip v2 400). The NGS analysis and composition of the salivary microbiome were determined by taxonomy assignment. Downstream bioinformatic analyses were performed in QIIME (v 1.9.1).ResultsClinical differences according to peri-implant condition status were found. Alpha diversity metrics revealed that the bacterial communities of participants with healthy peri-implant sites tended to have a richer microbial composition than individuals with peri-implantitis. In terms of beta diversity, bleeding on probing (BoP) may influence the microbial diversity. However, no clear partitioning was noted between the salivary microbiome of volunteers with healthy peri-implant sites or volunteers with peri-implantitis. The highest relative abundance of Stenotrophomonas, Enterococcus and Leuconostoc genus, and Faecalibacterium prausnitzii, Haemophilus parainfluenzae, Prevotella copri, Bacteroides vulgatus, and Bacteroides stercoris bacterial species was found in participants with peri-implantitis when compared with those with healthy peri-implant sites.ConclusionDifferences in salivary microbiome composition were observed between patients with healthy peri-implant sites and those with peri-implantitis. BoP could affect the diversity (beta diversity) of the salivary microbiome.

Metabolic Conditions and Peri-Implantitis.

Project description:Dental implants to replace lost teeth are a common dentistry practice nowadays. Titanium dental implants display a high success rate and improved safety profile. Nevertheless, there is an increasing peri-implantitis (PI), an inflammatory disease associated with polymicrobial infection that adversely affects the hard and soft tissues around the implant. The present review highlights the contribution of different metabolic conditions to PI. The considerations of both local and systemic metabolic conditions are crucial for planning successful dental implant procedures and during the treatment course of PI. Un- or undertreated PI can lead to permanent jaw bone suffering and dental implant losses. The common mediators of PI are inflammation and oxidative stress, which are also the key mediators of most systemic metabolic disorders. Chronic periodontitis, low-grade tissue inflammation, and increased oxidative stress raise the incidence of PI and the underlying systemic metabolic conditions, such as obesity, diabetes mellitus, or harmful lifestyle factors (cigarette smoking, etc.). Using dental biomaterials with antimicrobial effects could partly solve the problem of pathogenic microbial contamination and local inflammation. With local dentistry considering factors, including oral microbiota and implant quality control, the inclusion of the underlying systemic metabolic conditions into the pre-procedure planning and during the treatment course should improve the chances of successful outcomes.

The neck-region polymorphism of DC-SIGNR in peri-centenarian from Han Chinese population.

Project description:BACKGROUND: DC-SIGNR (also called CD209L) has been extensively studied on its role in host genetic predisposition to viral infection. In particular, variable number tandem repeat (VNTR) of the neck-region of DC-SIGNR is highly polymorphic and the polymorphism has been investigated for genetic predisposition to various infectious diseases, though conflicting results had been reported. As infection is a major cause of human death and a mechanism of natural selection, we hypothesized that VNTR polymorphism of DC-SIGNR might have an effect on human life span. METHODS: Here we collected 361 peri-centenarian individuals (age >or=94 for female and age >or=90 for male) and 342 geographically matched controls (age 22-53, mean 35.0 +/- 12.0) from Han Chinese. The VNTR polymorphism of the neck region was determined by PCR and genotype was called by separating the PCR products in agarose gel. RESULTS: A total of 11 genotypes and 5 alleles were found in our population. The genotype distribution, allele frequencies and homozygote proportion did not show a significant difference between peri-centenarian and control group. As gender differences in lifespan are ubiquitously observed throughout the animal kingdom, we then stratified the samples by gender. There was more 6/7 genotypes in female peri-centenarian group than that in female control group, at a marginal level of significance (5.56 vs. 1.28%, p = 0.041). The difference was not significant after correction by Bonferroni method. It suggests a possible differential effect of DC-SIGNR VNTR genotypes between sexes. Further studies are warranted to confirm our preliminary findings and investigate the mechanisms of the underlying functions. CONCLUSIONS: Our study indicated that there was absence of association between the neck region polymorphism of DC-SIGNR and longevity in Han Chinese population. But the question of whether the DC-SIGNR could affect longevity in a gender-specific pattern remains open.

Interleukin-27 rs153109 polymorphism and the risk of non-small-cell lung cancer in a Chinese population.

Project description:Non-small-cell lung cancer (NSCLC) has a multifactorial pathogenesis, and the genetic background may be one of the critical etiologic factors. Interleukin (IL)-27, a novel member of the IL-12 family, plays a vital role in antitumor immunity. The aim of the current study was to determine the association of a single nucleotide polymorphism of the IL-27 gene with the risk of NSCLC. The genotype of the IL-27 rs153109 polymorphism was analyzed in 388 patients with NSCLC and 390 healthy controls by using polymerase chain reaction-restriction fragment length polymorphism and DNA sequencing methods. In the patients with NSCLC, the frequencies of the GG, GA, and AA genotypes and the G and A alleles were 14.0%, 56.4%, 29.6%, 42.1%, and 57.9%, respectively. There were no significant differences in the genotype and allele distributions of the IL-27 rs153109 polymorphism between the patients with NSCLC and healthy controls (P>0.05). Furthermore, no association was determined between this polymorphism and different clinical characteristics in patients with NSCLC. Taken together, these findings suggest that the IL-27 gene may not be involved in the development of NSCLC in the Chinese population.
