Validity of the bath ankylosing spondylitis disease activity index for the evaluation of disease activity in axial psoriatic arthritis

Abstract: Objective. To assess the validity of the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) for the evaluation and definition of disease activity of axial psoriatic arthritis (PsA). Methods. Fifty-four peripheral PsA, 46 axial PsA, and 103 primary ankylosing spondylitis (AS) patients were assessed. Patients were classified as having axial PsA if they had grade 2 or higher unilateral sacroiliitis in the presence of spinal symptoms. The 3 groups of patients were evaluated using several measurements for … Show more

“…The study, including 2,044 consecutive patients with SpA, showed that primary AS had more severe axial involvement than those with spondylitis associated with psoriasis or IBD, while functional capacity, disease activity and quality of life were comparable among the groups studied [14]. Moreover, to support the assumptions that an equivalency between axial PsA and AS may not hold up, previous studies showed that the Bath Ankylosing Spondylitis Disease Activity score (BASDAI) in PsA was significantly lower than AS, correlated poorly with external indicators of disease activity [15] and may be influenced by the peripheral involvement, showing again the difference between these two conditions [16]. All these interesting data confirmed, to some extent, that axial PsA is quite different to the classical AS and is usually less severe [17].…”

“…The cutoff point (BASDAI score >4) for the definition of moderate to severe disease activity has been considered an appropriate criterion adopted from AS for axial disease in PsA [36], although the BASDAI in PsA may be influenced by the peripheral involvement [16].…”

“…First study by Taylor and Harrison showed that BASDAI was significantly lower in PsA than AS and did not correlate well with external indicators of disease activity [12]. The other study by Fernandez Sueiro et al found that the BASDAI performed similar in both peripheral and axial PsA however has not been found as a good instrument to assess disease activity in axPsA [13].…”

“…One of the composite indices for evaluating disease activity is BASDAI which is the most accepted and widely used tool in daily practice in patients with AS. Until now, only two previous studies assessed the validity of BASDAI as an indicator of disease activity in PsA [12,13]. First study by Taylor and Harrison showed that BASDAI was significantly lower in PsA than AS and did not correlate well with external indicators of disease activity [12].…”
