Ankylosing Spondylitis : Signs and Symptoms (2 of 5)

(gentle music) – Ankylosing spondylitis
is part of a larger family of arthritis called spondyloarthritis. Spondylo means vertebra,
or the bones of the back. And arthritis, of course means joint pain, stiffness, or swelling. Ankylosing spondylitis is an
inflammation type arthritis. It affects the spine, predominantly, the spine and the sacroiliac joints. It can manifest in other
ways, but it’s predominantly a spine inflammation type of arthritis. It is classically a disease
that begins insidiously, which means quietly and slowly. The patient may not know they have it. Only over years they may realize
that they’ve lost mobility and increasing pain starts
to become a feature. Typically it is starting
in younger adult age. Classically, for the
definition for diagnosis of ankylosing spondylitis
it should be age of onset less than 45 years. For the more diverse
general spondyloarthritis types of similar diseases, it
usually is less than 45 years. Now, in children, it
may occur less than 45, it can occur in less than 16 years of age, and that’s part of the spectrum of juvenile idiopathic arthritis. So it can occur, at any age, but typically it’s in
young adults or children. There is an inherited pattern, but not everybody can trace
that in their families. So a rheumatologist
will ask family history. It’s important to do that. But sometimes we can’t trace any family history. Interestingly, there are
other kinds of diseases that can be increased in a family, and will make rheumatologists
think there’s a likelihood that we’re dealing
with a spondyloarthritis, or ankylosing spondylitis type. And that’s psoriasis,
or ulcerative colitis, or Crohn’s disease, or
inflammation of the eye, we call uveitis. And those things tend
to happen in families, clustering families, and often
times in spondyloarthritis and ankylosing spondylitis. But sometimes we can’t hear
that in a family history. (gentle music)
