Abstract

Background and aim: Type 2 Diabetes Mellitus (T2DM) and Periodontitis (P) are prevalent multifactorial disorders worldwide, sharing a bidirectional relationship influenced by the genetic susceptibility of the host immune system. We investigated whether SNPs in the Interleukin 8 (IL8, alias CXCL8) gene could be associated with T2DM and Periodontitis. Methods: Genomic DNA was obtained from 874 Brazilian individuals divided into: Healthy group (n = 307), Periodontitis group (n = 334), and individuals affected by both T2DM and Periodontitis (T2DM\_P) group (n = 233). The SNPs -251(T>A) rs4073, +396(T>G) rs2227307 and +781(C>T) rs2227306 were genotyped by TaqMane. Multiple logistic regressions were used to determine the degree of association between polymorphisms (and haplotypes) with periodontitis and T2DM adjusted for known confounders. Results: The additive model revealed that the heterozygous AT(-251), GT(+396) and CT(+781) genotypes showed a lower risk for the diseased phenotypes, and carriers of the TTC/TTC haplotype were significantly susceptible to T2DM and Periodontitis concomitantly, as well to isolated Periodontitis (mainly the severe form). Conclusions: We concluded, for the first time, that these functional CXCL8 SNPs, and the homozygous TTC haplotype are relevant genetic factors for T2DM and Periodontitis as comorbidities, as well as for severe Periodontitis susceptibility in Brazilian population.
