[2025-09-30T02:47:47.547849] [PI reasoning] **Analyzing ankylosing spondylitis options**

I need to determine which option specifically pertains to ankylosing spondylitis. The HLA-B27 option, which stands out, is associated but not entirely specific. Sacroiliitis can occur in various conditions, making it less definitive. It's true that bilateral symmetrical sacroiliitis is characteristic of AS, and while HLA-B27 is present in a large percentage of AS patients, it also exists in some healthy individuals. Ultimately, I’m leaning towards sacroiliitis being more specific for AS in this context.
