comments, suggestion, and revised by experience AS researchers

80 parameters for AS diagnosis, 32 for AS assessment

Questionnaire

to assess the degree of importance of …parameters used for diagnosis and assessment of AS patients …

*** rheumatologist running clinical practice for at least 5-10 years

….. up to the individual opinion.. used in clinical practice, not in research….

* each item was scored as 1 or 2 or 3. 1 = not important2 = moderate important3 = extremely important

31 responders

from 10 APLAR countries

Results analysis

> 80% of responders scored as important ( 2 + 3)

Parameter for diagnosis

including: CRP, ESR, most plain films, and MRI 70% agree with B-27 study, less with RF

Parameter for assessment

Including: VAS, BASFI, BASDAI, GA, +BASMI

50% scored for MRI, 30% scored for B-27

Conclusion (1)

1. Majority of the responders agree that most parameters used for

diagnosis and assessment of AS patients are important.

2. However, limited numbers of these parameters have been using

in their clinical practice.

3. At least, characteristics of back pain, Schober test, chest and

eye exam, and film pelvis were evaluated by 80% of the

responders.

4. About half used MRI of SI joint for AS diagnosis, while one

third need genetic study.

5. Half of the responders used AS measurement parameters

(BASDAI, BASFI, VAS) and inflammatory parameters (CRP, ESR) during

AS assessment for their optimal care.
