Table 5 Comparison of histological markers between oligoarticular and polyarticular PsA

From: Synovial histopathology of psoriatic arthritis, both oligo- and polyarticular, resembles spondyloarthropathy more than it does rheumatoid arthritis

Marker Oligoarticular PsA (n = 28) Polyarticular PsA (n = 17) P
Lining layer thickness 1.0 (1.0–3.0) 1.0 (1.0–2.0) 0.492
Vascularity 1.5 (0–3.0) 2.0 (0–3.0) 0.661
Polymorphonuclear cells 0 (0–3.0) 0 (0–2.5) 0.126

CD68 sublining 1.5 (0–3.0) 1.0 (0–3.0) 0.845
CD163 lining 2.0 (0–3.0) 2.0 (0.5–3.0) 0.768
CD163 sublining 1.5 (0–2.5) 1 (0–2.5) 0.935
E-selectin blood vessels 0 (0–3.0) 0.25 (0–2.5) 0.594

  1. The Mann–Whitney U-test was used to evaluate markers scored semiquantitatively, and the χ2 test was used to evaluate markers scored as present or absent. Results are expressed as median (range), and markers evaluated as present or absent are expressed as percentage of positive results. P < 0.05 was considered statistically significant. PsA, psoriatic arthritis.
