Objective:
To analyze the relationship between the radiological progression and quality of life in ankylosing spondylitis (AS) patients using etanercept/methotrexate (MTX) combination therapy.
Methods:
A total of 153 AS cases fulfilling the 1984 modified New York diagnostic criteria were reviewed. All patients received radiological evolution at baseline and during a follow-up period. Radiological progression, clinical remission and life quality were recorded and analyzed for their relations.
Results:
The radiological assessments of mSASSS (modified Stoke ankylosing spondylitis spine score) were recorded at baseline, 3, 6 & 12 months after treatment. Life quality assessments were recorded with SF (short-form)-36 simultaneously. No significant radiological improvement was observed at the end points. However, most patients reported a significant improvement of life quality after a combination therapy of etanercept/MTX. BASDAI (Bath ankylosing spondylitis disease activity index), C-reactive protein and erythrocyte sedimentation rate demonstrated similar trends. With no relevance with mSASSS, life quality was significantly correlated with disease activity and pain control.
Conclusion:
The combination therapy of etanercept/MTX greatly improves life quality in AS patients. Yet clinical remission and pain control offer no hint of a suspension of radiological progression. Routine radiological assessment is required throughout the follow-up period of AS even if life quality index reaches a high level.
