Figure 5OCP frequency in peripheral blood is greater in PsA patients with erosive arthritis. PBMCs were obtained from ten PsA patients with and ten PsA patients without erosions on plain radiographs. The cells were cultured, fixed, and stained for TRAP, and osteoclast numbers were determined as described in Methods. Data are expressed as median osteoclasts per 10
6 PBMCs.
