Etanercept in Adult Patients with Early Onset Ankylosing Spondylitis
ROBERT D. INMAN, DANIEL O. CLEGG, JOHN C. DAVIS, JAMES B. WHITMORE, and ALAN SOLINGER ABSTRACT. Objective. To determine whether twice-weekly subcutaneous etanercept improves the signs and symptoms of adult patients with early onset ankylosing spondylitis (AS). Methods. A retrospective analysis was performed on a subgroup of patients with AS with onset < 18 years of age from a multicenter, double-blind, placebo-controlled, randomized study of etanercept in the treatment of patients with AS. Twenty patients met criteria and are presented. Results. As early as week four, 5/9 (56%) patients who received etanercept achieved an Assessments in Ankylosing Spondylitis 20% response (ASAS 20) versus only 1/11 (9%) of those who received placebo (p = 0.032). The observed ASAS 20 response continued through week 24, with 6/9 (66%) patients receiving etanercept responding, versus 2/11 of patients receiving placebo (p = 0.025). Conclusion. Etanercept improves signs and symptoms of early onset AS in adult patients for at least 24 weeks. (J Rheumatol 2006;33:1634–6) Key Indexing Terms:
