This study found that periodontitis increased renal inflammatory response in the UUO mouse model, but did not have a significant effect on renal interstitial fibrosis or renal function.
Objectives: To assess the effects of periodontitis on renal interstitial fibrosis in a mouse model. Materials and Methods: Thirty C57BL/6 male mice were divided into control, periodontitis (PD), unilateral ureteral ligation (UUO) and PD+UUO groups. Unilateral ureteral ligation was performed 6 days after periodontitis. After 2 weeks, all mice were sacrificed, and samples were collected for the assessment of gene expression, immune cells, biochemical indicators and renal pathology. Results: Expression of tumour necrosis factor-alpha, interleukin-1 beta, and Ly6G in the kidneys in the PD+UUO group was significantly greater than in the UUO group. The percentage of CD11b(+)Ly6G(+) cells was significantly higher in the PD+UUO than in the UUO group. Fibrotic areas in the kidneys in the PD+UUO group were slightly, but not significantly, greater than those in the UUO group. Kidneys from the PD+UUO group showed markedly higher gene expression of matrix metalloproteinase-9, but not alpha-smooth muscle actin or collagen I, than those in the UUO group. There were no significant differences in blood urea nitrogen, serum creatinine and uric acid between the PD+UUO and UUO groups. Conclusions: Periodontitis increases the renal inflammatory response without showing a significant influence on renal interstitial fibrosis or renal function in the UUO mouse model.
