Abstract

BackgroundAnti-citrullinated protein antibody (ACPA) responses may precede clinical onset of rheumatoid arthritis. Porphyromonas gingivalis peptidylarginine deiminase can citrullinate proteins possibly inducing autoimmunity in susceptible individuals. 
AimTo determine whether periodontitis, carriage of P. gingivalis, smoking and periodontal therapy influence ACPA titres. 
MethodsSerum and plaque samples were collected from 39 periodontitis patients before and after non-surgical periodontal treatment, and from 36 healthy subjects. Carriage of P. gingivalis was determined by PCR of plaque DNA. ACPA was determined by anti-cyclic citrullinated peptide (CCP) enzyme-linked immunosorbent assay (ELISA). Anti-P. gingivalis titres were determined by ELISA. 
ResultsUntreated periodontitis patients had higher anti-CCP antibody titres than healthy controls [three patients (8%) greater than manufacturer suggested assay diagnostic threshold (5 Assay Units/AU) versus none (0%); mean +/- SEM: 1.37 +/- 0.23 versus 0.40 +/- 0.10AU, p<0.0001]. Periodontitis patients who smoked demonstrated lower anti-P. gingivalis (15956 +/- 4385 versus 2512 +/- 1290Units/ml, p<0.05), but similar anti-CCP than non-smoking periodontitis patients (smokers: 1.31 +/- 0.35; non-smokers: 1.41 +/- 0.32AU). Healthy smokers demonstrated elevated anti-CCP titres (0.75 +/- 0.19AU), at levels between healthy non-smokers (0.15 +/- 0.05AU) and non-smoker periodontitis patients. Six months after periodontal treatment, there were significant reductions in anti-CCP (non-smokers p<0.05) and anti-P. gingivalis (all participants p<0.01).

ConclusionIn subjects with periodontitis, P. gingivalis infection may be responsible for inducing autoimmune responses that characterize rheumatoid arthritis.
