OBJECTIVE: We assessed the prevalence of selected clinical and radiological features of tendinous and ligamentous derangements in a consecutive sample of patients with systemic lupus erythematosus (SLE). METHODS: Consecutive patients with SLE with no comorbidities attending a tertiary care center were prospectively assessed and underwent plain radiographic evaluation of the pelvis. Radiographs were analyzed by 2 blinded observers; radiographic sacroiliitis was graded 0 to IV. To better assess sacroiliac (SI) involvement, a computed tomography (CT) scan of the SI joints was performed in patients with grade III sacroiliitis. Hip joints and pubis were also assessed as described. RESULTS: Of the 192 included patients, 89% were female, mean age was 36 years, and mean disease duration was 10 years. Inflammatory low back pain was reported by 10% of patients. Sacroiliitis of any grade was observed in 31 patients (16%), and grade III (confirmed on CT scan) sacroiliitis was observed in 6% (95% CI 3% to 9%). Osteitis pubis was diagnosed in 6% (95% CI 3% to 10%) and coxofemoral migration in 8% (95% CI 2% to 9%). Jaccoud's arthropathy was found in 23%. Demographic and clinical variables were not statistically associated with radiographic sacroiliitis. CONCLUSION: Sacroiliitis and other tendinous and ligamentous derangements are not uncommon in patients with SLE. Based on these features and on previous reports, the term "SLE-related tendinous and ligamentous derangements" may be used to establish a common framework for further research and reporting.
