Abstract

Abstract Background The association between rheumatoid arthritis (RA) and periodontitis is well established. Some children with juvenile idiopathic arthritis (JIA) phenotypically resemble adults with RA, characterized by the presence of anti-cyclic citrullinated peptide (CCP) antibodies. We sought to investigate an association between CCP-positive JIA and symptoms of periodontitis and antibodies to oral microbiota. Methods Antibodies to oral pathogensPorphyromonas gingivalis, Prevotella intermedia, andFusobacterium nucleatum were measured using ELISA in 71 children with CCP-positive JIA and 74 children with CCP-negative JIA. Oral health history was collected from 37 children with CCP-positive JIA and 121 children with CCP-negative JIA. T-tests, Chi-square tests, Mann–Whitney U tests, and multivariable regression were used to compare the groups. Results Compared to those with CCP-negative JIA, children with CCP-positive JIA were more likely to be female, older and non-Caucasian. Anti-P. gingivalis (p <0.003) and anti-P. intermedia (p <0.008) IgG antibody titers were higher in the CCP-positive cohort. Differences inP. gingivalis antibody titers remained significant after adjusting for age (p = 0.007). Children with CCP-positive JIA more likely reported tender/bleeding gums (43 % vs. 24 %, p < 0.02) compared to children with CCP-negative JIA. After controlling for age at collection, the odds of having tender/bleeding gums were 2.2 times higher in the CCP-positive group compared (95 % CI 0.98 – 4.83;p = 0.056). Conclusions Children with CCP-positive JIA have higher antibody titers toP. gingivalis and more symptoms of poor oral health, supporting a possible role for periodontitis in the etiology of CCP-positive JIA.
