  Purpose

Rheumatoid arthritis and periodontitis are two inflammatory diseases that share many pathophysiological similarities as some inflammatory mediators like TNF-alpha, IL-1, Il-6, Il-17, Il-12 et Il-17, RANK-L, or OPG The most severe or progressive forms of rheumatoid arthritis require in 10-30% of cases, the use of biotherapies such as anti-TNF-alpha, anti CD-20 and anti-lL-6. All these treatments results in, among other things, an increased risk of infection, both viral and bacterial.

These new biotherapies could have an impact on periodontal status

  • either by favouring sub gingival colonization of root surfaces by periodontal pathogenic bacteria and initiate periodontitis or exacerbate pre-existing periodontitis,
  • or a positive modulation of the host response by inhibiting bone resorption of the alveolar process.

To date, very few studies have been conducted on this subject which is really a translational research, involving several medical specialties.

Primary Outcome Measures:
  • Clinical attachment level [ Time Frame: 6 month ] [ Designated as safety issue: No ]
    Gain or loss obtained by periodontal probing.


Secondary Outcome Measures:
  • Detection of periodontopathogenic germs [ Time Frame: 6 month ] [ Designated as safety issue: No ]
    Detection of periodontopathogenic germs by RT - PCR - Q wich the bacterial samples will be made at the outset of the study and 6 month after the beginning of anti IL6 treatment.

  • Quantification of periodontopathogenic germs [ Time Frame: 6 month ] [ Designated as safety issue: No ]
    Quantification of periodontopathogenic germs by RT - PCR - Q wich the bacterial samples will be made at the outset of the study and 6 month after the beginning of anti IL6 treatment.

  • Detection of inflammation markers in the gingival fluid [ Time Frame: 6 month ] [ Designated as safety issue: No ]
    Detection and quantification of inflammation markers in the gingival fluid : IL-1, IL-6, IL-8, IL-10, IL-12, IL-15, IL-17, TGF- beta, TNF-alpha, IL-4 et IFn-gamma.

  • Quantification of inflammation markers in the gingival fluid [ Time Frame: 6 month ] [ Designated as safety issue: No ]

Arms Assigned Interventions
patient with parodontitis
Patient with rheumatoid arthritis and pparodontitis.
Other: oral exam and
The study will be conducted with patient presenting a rheumatoid arthritis and for which an anti IL6 biotherapy treatment is planned. Each patient will benefit a record oral exam that will evaluate his periodontal status and on a possible periodontitis associated. Bacterial samples and cytokine will be realized (in defined periodontal pocket or in the most affected periodontal pocket depending of the periodontal status of patients) before the IL6 biotherapy and 6 month after. A periodontal charting will be realized at the same time.
Patient without parodontitis
Patient with rheumatoid arthritis but periodontally healthy
