Periodontitis and Rheumatoid Arthritis: The Same Inflammatory Mediators?

Area of Science:

• Oral Health
• Rheumatology
• Immunology

Background:

• Periodontitis (PD) and rheumatoid arthritis (RA) exhibit a well-established association.
• PD is significantly more prevalent in RA patients, particularly in early-stage and seropositive individuals.
• The bacterium *P. gingivalis* may play a role in PD and RA pathogenesis through citrullination.

Purpose of the Study:

• To review the shared biomarkers for evaluating patients with both rheumatoid arthritis and periodontitis.
• To explore genetic factors, inflammatory cytokines, and autoantibodies implicated in both diseases.

Main Methods:

• Literature review of studies investigating the links between PD and RA.
• Analysis of genetic associations, including HLA-DRB1 alleles.
• Examination of the role of specific cytokines (TNF, IL6) and autoantibodies (anti-CCP).

Main Results:

• A significant association exists between HLA-DRB1 alleles and susceptibility to both PD and RA.
• Seropositive patients with RA may exhibit simultaneous structural damage in both wrist and periodontal sites.
• Data on other genetic polymorphisms and the role of cytokines and autoantibodies are varied, requiring further investigation.

Conclusions:

• Shared genetic factors like HLA-DRB1 alleles link PD and RA.
• Further research is needed to fully define the utility of shared biomarkers, including cytokines and autoantibodies, for evaluating patients with both conditions.
