Title: Rheumatoid Arthritis - Clinical Aspects IV: Non-biologic Drugs for Rheumatoid Arthritis: New Insights on Comorbidities and Adverse Events

Session Type: Abstract Submissions (ACR)

Background/Purpose: The aging population has resulted in large numbers of older individuals requiring treatment for rheumatoid arthritis (RA). We sought to describe the clinical characteristics of elderly (≥70 yrs) RA pts in a large prospective cohort and determine the frequency of DMARD use and factors associated with drug toxicities among elderly RA pts.   Methods: Data were obtained from the Consortium of Rheumatology Researchers of North America (CORRONA) registry; an independent prospective observational cohort with >30,000 RA patients from over 100 US academic and private practices.  We evaluated RA pts aged ≥ 70 yrs with ≥1 post-enrollment follow up (f/u) visit after age 70 [the ‘index visit (IV)]. Pts were classified as either aging with RA (RA onset <70) or older-age onset RA (RA onset ≥70). A subset of older RA patients with > 12 mo f/u beyond the IV was also identified. Demographic, clinical, and DMARD data were obtained. Unadjusted ORs were calculated to determine characteristics associated with DMARD or biologic exposure and drug-associated toxicities at IV and 12 mo f/u.   Results: 5801 RA pts age ≥70 yrs were identified with the following clinical features: 44% erosive, 30.8% joint deformities, mHAQ 0.7 ± 0.6. 4017 elderly RA patients were aging with RA (RA onset 56 ± 10.9 yrs) and 1784 had older-age onset RA (RA onset 75 ± 4.6 yrs). Mean age at IV was 74.9 ± 5.1 yrs with disease duration 13 ±11.6 yrs. 88.6% were on DMARD treatment (68.8% MTX, 34.8% biologic). Among those with 12 mo f/u (n=4077), 93.8% were on DMARD therapy (73.6% MTX, 42.8% biologic) with 16.1% adding a DMARD during f/u. Drug toxicity with non-biologic (1.6%) and biologic DMARDs (0.4%) was overall low. Among those with 12 mo f/u, 3.9% reported toxicity associated with non-biologic DMARD and 0.9% with biologic DMARD. The most commonly reported infection was URI (9%). Factors associated with DMARD, biologic use, or adverse events at the IV or 12 mo f/u are reported in Table 1.   Conclusion: Most elderly (≥70) RA pts in this large cohort received DMARD therapy, but DMARD and biologic toxicities were very low (<5%). Age of RA onset and age at f/u were not associated with increased biologic side effects. Greater RA severity and longer RA duration influenced if elderly RA patients were on DMARD or biologic therapy. Disability was strongly associated with risk of serious infection in this older age group. Limitations of this study include limited data on co-morbid conditions and precise medication timing. These data confirm that elderly RA patients tolerate DMARD and biologic therapy well with low rates of side effects and emphasize that treatment decisions for RA should never be based on age alone. However, disabled elderly RA patients are at high risk for serious infections. This vulnerable population should be the focus of future studies to determine strategies to improve outcomes beyond measures of RA activity alone.   Table 1.

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].
