Title: Osteoarthritis – Clinical Aspects - Poster II

Session Type: ACR Poster Session C

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

Background/Purpose:  Hand osteoarthritis (HOA) is a common and frequent cause of pain. HOA is a heterogeneous group of disorders with two main subsets including non-erosive disease and erosive, sometimes referred to as inflammatory, HOA. Few studies demonstrated inflammatory ultrasound changes and more severe clinical symptoms in patients with erosive compared with non-erosive disease, however the results are inconclusive. The aim was to evaluate progression of pain, stiffness, physical impairment and ultrasound features in patients with erosive and non-erosive HOA in a one-year longitudinal study.

Methods:  Consecutive patients with symptomatic HOA fulfilling the American College of Rheumatology (ACR) criteria were included in this study. Joint pain and swelling were assessed. Patients reported joint pain on 100 mm visual analogue scale (VAS). Pain, joint stiffness and disability were assessed by the Australian/Canadian OA hand index (AUSCAN). Radiographs of both hands were examined and erosive disease was defined by at least one erosive interphalangeal joint. Synovial hypertrophy and power Doppler signal (PDS) were scored with ultrasound. Synovitis was graded on a scale of 0–3 and osteophytes were defined as cortical protrusions seen in two planes. Patients were examined at baseline and one-year follow-up.

Results: Altogether, 129 patients (12 male) with symptomatic nodal HOA were included in this study and followed between April 2012 and January 2015. Out of these patients, 72 had erosive disease. Patients took symptomatic slow-acting drugs (SYSADOA) twice a year, non-steroidal anti-inflammatory drugs (NSAIDs) and analgesics on demand. Duration of morning stiffness (p<0.01) and number of clinically swollen joints (p<0.05) were significantly higher in patients with erosive compared with non-erosive disease at study entry. Duration of morning stiffness (p<0.05) become shorter in patients with erosive, but not in those with non-erosive disease, however the number of clinically swollen joints were not significantly changed at one year follow-up in both groups. According to the AUSCAN, patients with erosive compared with non-erosive disease had more pain (p<0.05) and stiffness (p<0.01) at study entry. Pain, but not stiffness, got worse (p<0.05) in patients with erosive compared with non-erosive disease. US-detected pathologies such as gray-scale synovitis total score (p<0.001), intensity of PDS (p<0.01) and number of osteophytes (p<0.01) were significantly higher in patients with erosive compared with non-erosive disease at study entry and got worse in gray-scale synovitis total score (p<0.01), intensity of PDS (p<0.01) and numerically also in number of osteophytes (p<0.1) at one-year follow-up. There were no significant differences in consumption of NSAIDs for OA between both groups.

Conclusion:  This study shows that pain associated with US-detected synovial hypertrophy, inflammatory signs and osteophyte formation is more severe in patients with erosive HOA than in patients with non-erosive disease and is more likely to progress over one year.

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].
