Anti-Cyclic Citrullinated Peptide Antibody and Periodontal Status in Rheumatoid Arthritis Patients.

OBJECTIVES

Studies have shown that periodontal disease and Rheumatoid Arthritis (RA) shared similar pathogenesis. Anti-Cyclic Citrullinated Peptide anibodies (anti-CCP) has recently been used for diagnosis of RA. Thus, this study aimed to assess the levels of anti-CCP antibodies and periodontal status in RA patients.

METHODS

Forty four RA patients were included in this study. The blood samples were analysed for anti-CCP levels. Plaque Score (PS), Gingivitis Score (GS), Probing Pocket Depth (PPD) and Clinical Attachment Loss (CAL) were recorded for assessment of periodontal status. Relevant clinical information was obtained from medical records.

RESULTS

Mean anti-CCP level was 180.8 ± 290.3 Unit/ml. The results showed that 27.3% patients had poor oral hygiene (PS >60%; mean anti-CCP 84.22 ± 167.51 Unit/ml), 52.3% had generalized gingivitis (mean anti-CCP 145.07 ± 269.17 Unit/ml), and 20.5% had mean CAL of >3mm (mean anti-CCP 56.81 ± 119.02 Unit/ml). None of patients presented with deep PPD > 4mm. The levels of anti-CCP showed no significant association with periodontal status (=0.27).

CONCLUSION

Most RA patients were positive for anti-CCP antibodies and presented with generalized gingivitis. Oral hygiene education should be reinforced in RA patients to prevent further progression of periodontal disease. Nevertheless, studies with larger sample size should be carried out to obtain more conclusive findings.
