Abstract
To assess the efficacy of long-term treatment with nonsteroidal antiinflammatory drugs (NSAIDs) on bone marrow oedema (BMO) of the sacroiliac joint in newly diagnosed axial spondyloarthritis (SpA) with a symptom duration of less than 4 years, a single-center, open-label study in a cohort of consecutive patients with newly diagnosed axial SpA was conducted. Eligible patients had magnetic resonance imaging (MRI)-determined BMO of the sacroiliac joint at baseline, had a symptom duration of less than 4 years, and were naïve to NSAIDs. After the baseline MRI, an optimal dose of NSAID was administered for 24 or 48 weeks. BMO of sacroiliac joint was quantified by applying the Spondyloarthritis Research Consortium of Canada (SPARCC) system. Disease activity was expressed using the Ankylosing Spondylitis Disease Activity Score (ASDAS). Primary end points were improvement in BMO of sacroiliac joint at week 24 or week 48. Forty-three patients were recruited, and 33 patients eventually completed the study, including 10 patients having follow-up MRI at week 24 and 23 patients having follow-up MRI at week 48. Overall, the mean of SPARCC score decreased from 21.8 ± 16.1 at baseline to 10.2 ± 12.8 at follow-up (p < 0.001). 75.8% of the patients displayed a minimally important change, and 30.3% became free of BMO. The mean of ASDAS-CRP decreased from 3.1 ± 1.0 at baseline to 2.1 ± 1.0 at follow-up (p < 0.001). Long-term treatment with optimal dose NSAIDs could significantly alleviate BMO of sacroiliac joint in early and active axial SpA.
