There is an article by Tammy Laber "Struck in the prime of life" in the Arthritis supplement page TAS4 in today's Globe (Friday March 3, 2006).
A good overview, then it talks about biologics.
There is one sentence at the end of this paragraph that bothers me though
Often striking men in their prime, AS takes on average five years to diagnose. During that time the disease progresses; damage to the spine may become irreversible. Yet, AS can be confirmed with a blood test.
Err, no, I don't think so. Maybe just a science or an editing gap but I don't think this is right. HLA-B27 is present in most people with AS, but it's not diagnostic of AS (it's also present in people without AS).
