Key clinical point: A substantial proportion of patients with psoriatic arthritis (PsA) who received biological disease-modifying antirheumatic drug (bDMARD) therapy showed osteoproliferative lesions on a lumbar radiograph, with osteophytes being the most common.
Major finding: Osteophytes were the most common lesions and were detected in 42.3% of patients, with 18.1% of patients being diagnosed with grade ≥2 osteophytes. At least one syndesmophyte was detected in 24.2% of patients, with 9.3% and 19.8% of patients showing bridging and corner syndesmophytes, respectively. Ambiguous lesions were detected in 7.1% of patients.
Study details: Findings are from an analysis of 182 patients with PsA who received bDMARD therapy and underwent lumbar radiography assessment.
