Journal of periodontology 2013 FebThe aim of this study is to evaluate the effect of autoimmune diseases (AIs), as well as anti-tumor necrosis factor-α (TNF-α) therapy on the clinical and immunologic parameters of the periodontium. Thirty-six AI patients (12 rheumatoid arthritis [RA], 12 psoriatic arthritis, and 12 systemic sclerosis) were recruited together with 12 healthy (H) and 10 RA patients receiving anti-TNF-α therapy (RA+). Periodontal indices including plaque index, gingival index (GI), probing depth (PD), and bleeding on probing (BOP) were measured, and gingival crevicular fluid (GCF) was collected from five deepest pockets using papers strips. The TNF-α level was analyzed using enzyme-linked immunosorbent assay. Analysis of variance test was used for statistical comparison between groups, whereas Pearson linear correlation coefficient test was used to examine the association between TNF-α and periodontal status indices. The three AI subgroups were very similar in clinical and immunologic parameters. GI was greater in the AI patients compared to the H and RA+ groups (1.91 ± 0.54, 1.21 ± 0.67, and 1.45 ± 0.30, respectively, P = 0.0005). AI patients exhibited significantly more BOP than H and RA+ (46.45% ± 17.08%, 30.08% ± 16.86%, and 21.13% ± 9.51%, respectively, P = 0.0002). PD in H and RA+ groups were lower than in the AI (3.47 ± 0.33, 3.22 ± 0.41, and 3.91 ± 0.49 mm, P = 0.0001). Number of sites with PD >4 mm was higher in AI patients compared to H and RA+ (42.44 ± 17.5 versus 24.33 ± 15.62 versus 33.3 ± 6.6, P = 0.0002). GCF TNF-α was higher among the AI patients (1.67 ± 0.58 ng/site) compared to 1.07 ± 0.33 ng/site for the H group and 0.97 ± 0.52 ng/site for the RA+ group (P = 0.0002). A significant positive correlation was found between PD and TNF-α levels in the GCF (r = 0.4672, P = 0.0002), BOP (r = 0.7491, P = 0.0001), and GI (r = 0.5420, P = 0.0001). Patients with AI diseases have higher periodontal indices and higher TNF-α levels in GCF than H controls. Anti-TNF-α treatment appears to reverse this phenomenon.
