Abstract

Background Patients (pts) with oligoarticular psoriatic arthritis (PsA) report quality-of-life impairment similar to polyarticular PsA pts despite less joint involvement. In the 2020 Understanding Psoriatic Disease Leveraging Insights for Treatment (UPLIFT) survey, we evaluated other aspects of disease burden in pts with oligoarticular (≤4 joints) and polyarticular (>4 joints) PsA.

Objectives To explore joint involvement distribution and relative disease burden in pts with self-reported healthcare provider (HCP)–diagnosed PsA who self-identified with oligoarticular vs polyarticular joint involvement.

Methods UPLIFT was a multinational Web-based survey in adults who reported an HCP diagnosis of PsA and/or psoriasis. This analysis evaluated demographics, disease characteristics, joint distribution, and quality-of-life measures in pts with PsA with or without psoriasis with self-identified oligoarticular vs polyarticular joint involvement. Small joint classification includes foot/toes, hands/fingers, and thumbs; intermediate joints includes wrists, elbows, and ankles; and large joints includes shoulders, hips, and knees.

Results Of the 1256 pts with PsA completing the survey, 44% had oligoarticular PsA and 56% polyarticular PsA. The polyarticular PsA group had higher mean age, fewer males, and more pts with body mass index ≥25 kg/m2 (Table 1). Prevalence of depression, hypertension, and diabetes was generally similar between groups (Table 1). In pts with oligoarticular and polyarticular PsA, respectively, involvement of large joints was most prevalent (63%, 91%), followed by intermediate (46%, 87%) and small (20%, 76%) joints. Axial involvement was less prevalent in pts with oligoarticular (30%) vs polyarticular (67%) PsA. Common areas of joint involvement were the knees, elbows, and shoulders for oligoarticular PsA pts and the knees, hands, and elbows for polyarticular PsA pts (Figure 1). Involvement in the hands, wrists, thumbs, feet, and ankles was proportionately greater in polyarticular pts vs oligoarticular pts. Dactylitis, enthesitis, and nail disease, respectively, were each present in approximately one third of oligoarticular PsA pts and more than half of polyarticular PsA pts. Mean Patient Assessment of PsA Severity, Health Assessment Questionnaire (HAQ)-8, and Psoriatic Arthritis Impact of Disease 12-item (PSAID-12) scores indicated similar disease burden between the two groups (Table 1). In both groups, >70% reported an unacceptable PsA symptom state (PSAID >4), and >60% had Patient Health Questionnaire 2-item (PHQ-2) score ≥3, consistent with positive screening for depression (Table 1).

Demographics and Patient Characteristics

Conclusion In the UPLIFT survey, almost half of pts with PsA self-identified with oligoarticular PsA. Both oligoarticular and polyarticular PsA groups experienced similar levels of disease burden, including a high prevalence of an unacceptable PsA symptom state and a PHQ-2 score ≥3, indicative of a positive screen for depression.
