Abstrakt: Objectives: In this cross-sectional study we investigated antibody titres against cyclic citrullinated peptides derived from filaggrin (anti-CCP) and citrullinated α-enolase (anti-CEP-1) among patients with RA as a function of periodontal findings.
Methods: 107 patients with RA (median age 56 years, 75% females) were included. For periodontal diagnoses missing teeth, periodontal epithelial surface area, periodontal inflamed surface area and periodontal diagnosis according to the working group's guidelines of the Center for Disease Control and Prevention were determined. Subgingival bacterial DNA of five periodontopathic bacteria was assessed by PCR with sequence-specific oligonucleotides. Anti-CCP and anti-CEP-1 antibodies in plasma samples were investigated using enzyme-linked immunosorbent assays. Low resolution human leukocyte antigen (HLA) typing was carried out using PCR with sequence-specific primers.
Results: PESA was found associated with a low adjusted odds ratio for anti-CCP positivity (OR=1.002, p=0.040). All patients who were infected with Aggregatibacter actinomycetemcomitans were simultaneously anti-CCP positive (p=0.043). HLA-DRB1*13 lowered the adjusted odds ratio for anti-CCP (OR=0.073, p=0.002) and anti-CEP-1 (OR=0.068, p=0.018) positivity whereas HLA-DRB1*07 indicated a lower risk only for demonstrable anti-CCP antibodies (OR=0.079, p=0.004). HLA-DRB1*04 was associated with increased adjusted odds ratio for anti-CEP-1 positivity (OR=4.154, p=0.005) and the simultaneous proof of both investigated autoantibodies (OR=3.725, p=0.011).
Conclusions: Among patients with RA periodontitis may be a minor risk factor for anti-CCP positivity. Our data first provide evidence that an infection with A. actinomycetemcomitans is associated with an increased formation of anti-CCP. HLA phenotype proved to be a significant risk indicator for both investigated antibodies.
