ABSTRACT
PURPOSE:
To investigate the relationship between polymorphism of cytochrome P450, family 2, subfamily A, polypeptide 6(CYP2A6) and periodontitis, the expression of inflammatory cytokines in 123 Han smokers.METHODS:
From October 2018 to October 2019, a total of 123 smokers with periodontitis were selected as the experimental group, and 125 non-smokers as the control group. The general data of the patients were collected, including age, gender, body mass index (BMI), chewing and brushing habits, as well as molar condition; plaque index (PLI), gingival bleeding index (BI), periodontal probing depth (PD) and attachment loss (AL) were detected. CYP2A6 was amplified by PCR. The level of interleukin (IL)-17, IL-1, IL-6, IL-23 and tumor necrosis factor-α (TNF-α) in GCF was detected by enzyme-linked immunosorbent assay(ELISA). SPSS 25.0 software package was used for statistical analysis of the data.RESULTS:
There was significant difference in gender, PLI, IL-17, IL-1, IL-6, IL-23, TNF-α level in GCF between the two groups(Pï¼0.05). All samples were amplified by PCR. Among them, 23 were not amplified, which were identified as CYP2A6 deletion type (CYP2A6del), including 5 in the experimental group and 18 in the control group; 225 were amplified and identified as CYP2A6 wild type(CYP2A6wt), including 118 in the experimental group and 107 in the control group. There was significant difference in CYP2A6 genotype between the two groups(Pï¼0.05). In the experimental group, the level of IL-1 and PLI of different CYP2A6 genotypes was significantly different(Pï¼0.05); and in the control group, the level of IL-17 and PLI of different CYP2A6 genotypes was also significantly different(Pï¼0.05).CONCLUSIONS:
There are differences in CYP2A6 genotype between smokers and non-smokers in Han population with periodontitis, but the relationship between CYP2A6 genotype and inflammatory cytokines is not clear.
