Consequences of Anti-interleukin 6 Immunotherapy Treatment for Rheumatoid Arthritis on Periodontium (ParoPAR)
Multicenter, Prospective Study, on the Consequences of Anti-interleukin 6 Immunotherapy Treatment for Rheumatoid Arthritis on: - Healthy and Pathological Periodontium - The Level of Expression of Some Markers of Inflammation and Periodontal Pathogenic Bacteria in Periodontal Sulci and Periodontal Pockets
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.

Other: patient with parodontitis
Patient with rheumatoid arthritis and pparodontitis.
|
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.

Other: Patient without parodontitis
Patient with rheumatoid arthritis but periodontally healthy

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.
