Background The existence of EAM in Ankylosing Spondylitis(AS) may change the treatment options and the ratio of EAM varies according to race and countries.

Objectives This study was planned to evaluate the involvement ratio of EAM according to organ systems and to determine the relation between EAM and disease activity and functional level in Turkish population

Methods This is a multicenter study and supported by Turkish League Against Rheumatism (TLAR) AS study group. In Turkey a web-based registry sistem project was developed by TLAR organisation and this study was based on these data. A total of 2276 AS patients were included the study. The patients with EAM were selected and its distibution over the organs including; ocular, pulmonary, cardiac, renal and neurological involvements were assessed. In order to determine the factors that affects the involvement of EAM, laboratory parameters such as erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), the duration of morning stiffness, Bath ankylosing spondylitis disease activity index(BASDAI) and Bath ankylosing spondylitis functional index (BASFI) were evaluated.

Results In this study 158 patients with a ratio of %6.9 had EAM. Ocular involvement was most often (%76.6) and followed by pulmonary (%14.6), cardiac (%9.5), renal (%8.9) and neurological involvement (%2.5) respectively. We observed that there was statistically significant correlation between BASDAI scores and ocular (p=0.008), cardiac (p=0.010) and renal involvement (p=0.005). Also significant correlation was found between BASFI and ocular, cardiac and renal involvement (p=0.037,p=0.010 and p=0.013 respectively). However disease activity and functional level had no relation with pulmonary and neurologic involvement. Additionally no statistically significant correlation was observed between morning stiffness, ESR and CRP levels with the existence of EAM (p>0.05).

Conclusions The most frequent EAM was ocular involvement in Turkish AS patients. The existence of ocular,cardiac and renal involvements are closely related with disease activity and functional capacity.
