Title: Rheumatoid Arthritis – Clinical Aspects - Poster I: Clinical Characteristics/Presentation/Prognosis

Session Type: ACR Poster Session A

Session Time: 9:00AM-11:00AM

Background/Purpose:

Even now, in clinical practice, most of RA patients have long-standing disease and structural damage in their joints. Reconstructive joint surgery should be needed for further improvements of physical function for long-standing RA patients. It is very important to understand how much range of motion (ROM) should be needed to gain better physical function in each case.

The purpose of this study is to explore the characteristics of functional impairment in RA patients who were needed joint surgery based on ROM of joints using multicenter prospective cohort.

Methods:

We conducted this prospective study from 2012 to2015 (Study registration: UMIN000012649) supported by grant from the Japanese Ministry of Health, Labour and Welfare.

We collected data on age, sex, disease duration, drug therapies, disease activity, and physical functional including HAQ-DI. Joint range of motion including shoulder, elbow, wrist, hip knee ankle was also measured. ROM in each joint by disability in HAQ-DI categories was compared by ANOVA with adjustment of age and sex. Association between ROM of each joint and no disability of daily activity in each 8 HAQ-DI categories and cut-off values for no disability were determined using ROC curve. Independent impact of ROM each joint was also determined multivariate analysis.

Results:

460 patients who have data of ROM of any joints in registry were analyzed. Mean values for age, disease duration, DAS28-CRP and sex were 64.5 years, 16.7 years, 3.14, and 86.8% female, respectively.  Median values for CRP was 0.2 mg/dl.  We could find significant association between ROM and disability in HAQ-DI category based on area under the ROC curve (AUC>0.7) as follows; shoulder in dressing, wrist in eating, hip, knee ankle in walking, shoulder in hygiene, shoulder in activity. The cut-off values of ROM of each joints for daily activity in each HAQ-DI category was shown in Table 1 using ROC curves (Table 1). Multivariate analysis adjusting disease activity, age, and sex, showed which joint had significant impact on disability of each category (Table 2).

Conclusion: ROMs of the joints were significantly associated with functional impairment. The information should be important for assessment of disability in patients with long-standing RA. The cut-off of ROM as shown in this study could be target of surgical procedure. It will be validated by further analysis of longitudinal data of this study.

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].
