Abstract:
PURPOSE: Periodontitis and rheumatoid arthritis (RA) share a similar inflammatory pathogenesis. Porphyromonas gingivalis (Pg) can induce anticyclic-citrullinated peptide autoantibodies (anti-CCP antibodies), a key factor in the development of RA. This study aimed at evaluating the relationships between the 2 diseases and identifying the clinical implications thereof, with a focus on periodontal pathogens in Korean adults. METHODS: A total of 260 RA patients and 86 age- and sex-matched control patients without arthritis were enrolled in this prospective cross-sectional study. Periodontal indices and the prevalence and amount of periodontal pathogens were compared between the groups. Correlations between periodontal and RA indices were examined, as were correlations between 9 periodontal pathogens and RA indices. RESULTS: The RA group had significantly higher values than the control group for all investigated periodontal indices (P < 0.05) except the number of teeth. The gingival index (GI) was correlated with the disease activity score 28 (DAS28) (r = 0.125, P = 0.049), RA disease duration (r = 0.253, P < 0.001), erythrocyte sedimentation rate (ESR) (r = 0.162, P = 0.010), and anti-CCP antibody titer (r = 0.205, P = 0.004). Probing pocket depth (PPD) was correlated with ESR (r = 0.139, P = 0.027) and anti-Pg antibody titer (r = 0.203, P = 0.001). Bleeding on probing (BOP) was correlated with DAS28 (r = 0.137, P = 0.030), RA disease duration (r = 0.202, P = 0.001), ESR (r = 0.136, P = 0.030), anti-Pg antibody titer (r = 0.177, P = 0.005), and anti-CCP antibody titer (r = 0.188, P = 0.007). Clinical attachment level (CAL) and periodontitis severity were correlated with anti-Pg antibody titer (the former r = 0.201, P = 0.002; the latter r = 0.175, P = 0.006). The quantity of Pg was positively correlated with the serum anti-Pg antibody titer (r = 0.148, P = 0.020). CONCLUSIONS: The GI, BOP, and PPD showed positive relationships with several RA indices. The anti-Pg antibody titer had positive relationships with PPD, BOP, CAL, and periodontitis severity. Thus, increasing values of periodontal indices could be used as a risk indicator of disease development in RA patients, and an increasing anti-Pg antibody titer could be considered as a warning sign in RA patients suffering with periodontitis.
