Risk factors of periodontal disease in maintenance hemodialysis patients

To explore the characteristics and relevant risk factors of periodontal disease (PD) among hemodialysis patients. Uremic patients on maintenance hemodialysis from November 2015 to March 2016 were retrospectively reviewed. Patients were divided into a PD group and a non-PD group. Demographic and laboratory data were collected and analyzed. In all, 136 uremic patients (79 males and 57 females, aged 50.8 ± 15.3 years) on maintenance hemodialysis were included in this study. The incidence of PD increased with age. Hemodialysis patients most likely developed PD if they were male, smokers, or diabetic (P = .009, <.001, and <.001, respectively). Patients brushing their teeth twice daily had significantly less chance of developing PD as compared with those only brushing once daily (P < .001). Hemodialysis patients in the PD group had significantly higher levels of total cholesterol, high-sensitivity C-reactive protein, fasting blood glucose, and peripheral white blood cell counts, compared with the non-PD group (all P < .001). Logistic regression analysis revealed that diabetes, total cholesterol, high-sensitivity C-reactive protein, and peripheral white blood cell count were independent risk factors for developing PD, whereas teeth brushing twice daily and serum calcium were favorable factors for maintenance hemodialysis patients against PD. Identification of risk factors provides a theoretical basis for prevention and improvement of PD among maintenance hemodialysis patients.
