The role of anti-cyclic citrullinated peptide antibody in periodontal disease

The anti-Cyclic Citrullinated Peptide Antibodies (anti-CCP) are produced locally in the inflamed synovium of Rheumatoid arthritis (RA) patients, suggesting that citrullinated proteins are located in the inflamed synovium. In scientific literature were find periodontal bacterial DNA in serum and synovial fluid of RA with PD patients. RA and adult periodontitis share common pathogenetic mechanisms and immunologic and pathological findings RA. One oral pathogen strongly implicated in the pathogenesis of periodontal disease (PD), Porphyromonas. gingivalis, possesses a unique microbial enzyme, peptidylarginine deiminase (PAD), the human equivalent of which has been identified as a susceptibility factor for RA. Under this point of view, we speculate about the presence of anti-CCP antibodies in sera of PD with RA patients. We conducted this study to evaluate and compare the diagnostic and predictive utility of anti-CCP antibodies in patients with PD and patients with PD and RA. Anti-CCP antibody was not found in 21 sera (U/ml<10), included RA controls, while only 1 patient with chronic PD and probing depth of 7,1 mm was identified positive for anti-CCP (22.2 U/ml). Our data do not support a role for anti-CCP in diagnoses of periodontal disease. Copyright © by BIOLIFE, s.a.s.
