Brief Summary

The inclusion criteria was patients who aged 18 or older with ankylosing spondylitis, fulfilled the 1984 modified New York criteria for AS. Inclusion criteria enriched the AS patients with clinical remission, including the following definition: 1. Administration of etanercept 50 mg for 6-week period at least; 2. Acquisition of Assessment of SpondyloArthritis International Society criteria 20(ASAS20) response at the end of the treatment. We excluded patients who have developed to complete spinal fusion. We also excluded patients with kidney disease induced by other conditions; pregnancy; suckle; accompany other chronic diseases; various infections in acute stage; and other infectious diseases. At the end of the trial, patients who fulfilled the inclusions would stop etanercept treatment. Cotherapy with disease modifying anti-rheumatic drugs or non-steroidal anti-inflammatory drugs could be continued if maintained at a stable dose;Patients were followed up from the time of etanercept withdrawal per 6 weeks for 3 years by telephone. If symptoms suggestive of relapse or other problems occurred, patients were invited to come back to the center. Relapse after etanercept withdrawal was defined as an increase Bath Spondylitis Disease Activity Index(BASDAI)15 score goes back to 80 percentages of it at the beginning of the trial16. The following data were collected: demographic and disease characteristics, therapeutic modification, clinical values (BASFI, Bath Ankylosing Spondylitis Global Score (BAS-G)), Ankylosing Spondylitis Disease Activity Score (ASDAS)1718) and biologic values at baseline of the trial and the time of relapse. Adverse events and other safety measures were also collected.

Conditions

Spondylitis, Ankylosing; Recurrence

Outcome Measures

Primary Outcomes (1)

• The status of relapse

  The cumulative probabilities of relapse at 1, 2, and 3 years were 45.7%，57.1% and 60.0%, respectively.

  3 years

Secondary Outcomes (1)

• Bath Spondylitis Disease Activity Index(BASDAI) score

  3 years

Study Arms (1)

Etanercept, AS

EXPERIMENTAL

The patients were diagnosed with ankylosing spondylitis and obtained the ASAS20 response after etanercept treatment. Then they were discontinued to etanercept and received no treatment except DMARDs or NSAIDs which had used before.

Drug: Etanercept

Interventions

Etanercept DRUG

Etanercept must be discontinued. Cotherapy with disease modifying anti-rheumatic drugs or non-steroidal anti-inflammatory drugs could be continued if maintained at a stable dose for at least 4 weeks.

Also known as: enbrel
