Krankheitsaktivitätsmessung im klinischen Alltag bei Spondyloarthritiden

Spondyloarthritides are a group of inflammatory rheumatic diseases that affect the axial and peripheral skeleton and also extraskeletal organs. To comprehensively estimate the activity of the diseases, a whole range of parameters covering all aspects of the disease would therefore be necessary but valid parameters have been developed only for patients with ankylosing spondylitis and psoriatic arthritis. It has been shown that the Bath ankylosing spondylitis activity score as a composite measure and single items such as nocturnal pain, intensity and duration of morning stiffness, patients global assessment of disease activity and the Maastricht ankylosing spondylitis enthesitis index are valid parameters to estimate AS disease activity in clinical practice. To estimate the disease activity of psoriatic arthritis in clinical practice, recommended parameters include the activity of peripheral arthritis and psoriasis, patients’ global assessment of disease activity, and physical function.
