Title: RA – Diagnosis, Manifestations, & Outcomes Poster II

Session Type: Poster Session B

Session Time: 10:30AM-12:30PM

Background/Purpose: Cardiovascular Disease (CVD) is the main cause of death in patients with Rheumatoid Arthritis (RA), and a significant portion of CVD events occur in patients without traditional risk factors. Substantial evidence supports that periodontitis is a risk factor for mortality from coronary heart disease and cerebrovascular disease, as well as all-cause mortality. The association between tooth loss in RA patients and all-cause mortality and cardiovascular mortality needs further study.

Methods: This study included 582 participants (221 males, 361 females; age range 20-85 years) from the National Health and Nutrition Examination Survey (NHANES) between 1999 and 2004. Weighted multivariate Cox proportional hazards models were used to assess the association between the number of teeth in RA patients and all-cause mortality and cardiovascular mortality.

Results: Over a median follow-up of 16.8 months, a decrease in the number of permanent teeth was associated with factors such as age, Body Mass Index(BMI, Poverty Income Ratio (PIR), Education, and Chronic Obstructive Pulmonary Disease (COPD) (all P< 0.05) (Table 1). 264 participants died, with 82 deaths due to CVD. After adjusting for age, smoking (never, former, and current), ethnicity, education, annual family income, Healthy Eating Index 2015 scores, BMI, hypertension, diabetes, COPD, and cancer, participants with more than 8 missing teeth had the highest risk of all-cause mortality (Hazard Ratio [HR] 4, 95% Confidence Interval [CI] 1.66, 9.67) compared to those with no missing teeth, while those with complete tooth loss had the highest risk of cardiovascular mortality (HR 39.01, 95% CI 5.52-274.89) (Table 2&Figure).

Conclusion:  This study is the first to find a dose-dependent relationship between the number of teeth in RA patients and all-cause mortality and CVD mortality. The number of teeth is a suitable indicator of oral health, indicating an association between oral health and CVD in RA patients.

All abstracts accepted to ACR Convergence are under media embargo once the ACR has notified presenters of their abstract’s acceptance. They may be presented at other meetings or published as manuscripts after this time but should not be discussed in non-scholarly venues or outlets. The following embargo policies are strictly enforced by the ACR.

Accepted abstracts are made available to the public online in advance of the meeting and are published in a special online supplement of our scientific journal, Arthritis & Rheumatology. Information contained in those abstracts may not be released until the abstracts appear online. In an exception to the media embargo, academic institutions, private organizations, and companies with products whose value may be influenced by information contained in an abstract may issue a press release to coincide with the availability of an ACR abstract on the ACR website. However, the ACR continues to require that information that goes beyond that contained in the abstract (e.g., discussion of the abstract done as part of editorial news coverage) is under media embargo until 10:00 AM ET on November 14, 2024. Journalists with access to embargoed information cannot release articles or editorial news coverage before this time. Editorial news coverage is considered original articles/videos developed by employed journalists to report facts, commentary, and subject matter expert quotes in a narrative form using a variety of sources (e.g., research, announcements, press releases, events, etc.).

Violation of this policy may result in the abstract being withdrawn from the meeting and other measures deemed appropriate. Authors are responsible for notifying colleagues, institutions, communications firms, and all other stakeholders related to the development or promotion of the abstract about this policy. If you have questions about the ACR abstract embargo policy, please contact ACR abstracts staff at [email protected].
