Ankylosing Spondylitis and Rheumatoid Arthritis: Serum Levels of TNF- and Its Soluble Receptors during the Course of Therapy with Etanercept and Infliximab
Figure 1
Changes in disease activity after 12 weeks of anti-TNF-α therapy. Disease activity scores were determined prior to the start of and at 12 weeks into treatment with infliximab and etanercept. Disease activity was assessed using the Bath ankylosing spondylitis disease activity index (BASDAI) and the disease activity score 28 (DAS28) in patients with ankylosing spondylitis (a) and rheumatoid arthritis (b), respectively. Significant differences in disease activity are indicated by the values.
