Background High levels of tumor necrosis factor (TNF) receptors (TNFRs; TNFR1 and TNFR2), markers of inflammation, have been reported as significant predictors of mortality in hemodialysis patients.Porphyromonas gingivalisis a major pathogenic bacterium involved in periodontitis, which induces systemic inflammation. We investigated the association between the abundance ofP. gingivalisin saliva and serum TNFR levels in hemodialysis patients. Methods A cross-sectional study was conducted on 121 hemodialysis patients visiting a clinic in the Tokyo metropolitan area. Medical interviews and examinations, comprehensive dental examinations, bacterial examinations forP. gingivalisin saliva, and measurements of circulating TNFR levels were conducted. Multiple linear regression analysis was performed to evaluate the association between the number ofP. gingivalisand circulating TNFR levels. Results TNFR1 and TNFR2 were positively correlated with high-sensitivity C-reactive protein (hsCRP). Severe periodontitis was significantly associated with the number ofP. gingivalisin saliva but not serum TNFR levels. The number ofP. gingivaliswas significantly associated with both TNFR1 and TNFR2 levels in sera after adjusting for age, sex, body mass index, smoking status, history of diabetes, prior cardiovascular disease events, serum levels of hsCRP and albumin, and severity of periodontitis [for TNFR1: coefficient 0.76, 95% confidence interval (CI) 0.14-1.37,p = 0.02; for TNFR2: coefficient 0.95, 95% CI 0.09-1.80,p = 0.03]. Conclusion Circulating TNFR levels are associated with the number ofP. gingivalisin saliva after adjusting for relevant clinical factors.
