A multicenter registry to explore the clinical outcome of Chinese adult patients with active Ankylosing Spondylitis \*AS\* treated with adalimumab,prescribed according to the local label,in the real world practice
This registry will be conducted in a non-interventional setting for AS patients using adalimumab in China.The primary objective is to evaluate the effectiveness and safety of adalimumab in Chinese AS patients in real world clinical practice.The secondary objective is to 1)compare the clinical outcome in patients with or without good persistence with adalimumab;2)investigate the predicting factors of a good clinical response after discontinuation of adalimumab.

Time frame: week12
Effectiveness of adalimumab measured as change in BASDAI,Ankylosing Spondylitis Disease Activity Scores *ASDAS*,Visual Analogue Scale *VAS* in pain,Patient Global Assessment *PtGA* with adalimumab treatment.
Time frame: week 12
Proportion of patients who achieve each of the ASDAS disease state categories(inactive,mild,moderate,high) with adalimumab treatment.
Time frame: week 12
Improvement of extra-articular manifestation with adalimumab treatment compared to baseline: uveitis flare rates, patient proportion with VAS scale at 1 in IBD PtGA, patient proportion with skin lesion clear or almost clear in psoriasis PGA.
