Spondylitis Infection Or Inflammation Of The Spinal Joints

By | February 1, 2019

Ankylosing spondylitis

We're goingto refer to ankylosing spondylitis as AS. So you don't have to keephearing me say this long thing. But if we go word by word just once, you'll see that ankylosing means fusion. So it describes the spinebeing fused together. Spondy, this first part ofthe word, refers to the spine. and then itis anywhere is inflammation.

So this is an inflammation of the spine and at the sacroiliac joint, actually, and it leads to the fusion of the area. There's some buzz words surrounding it. So one of them would bethat it is the poster child for a group of different diseases that are referred to collectively as the seronegative spondyloarthropathies.

Spondylo, so again, that's the spine, and then arthro, whichrefers to joints in general, and then pathologies or illnesses. So what this means is that they are rheumatoid factor negative. They do not have rheumatoid factor. But they also can appearlike rheumatic joint diseases because it's systemic and itinvolves the immune system.

So speaking of the immune system, the other buzz word you need to know is HLAB17. I'm sorry, I always say that. It's B27. Again, it's part of the immune system. It's an antigen on the surface of the cell that can be recognized by Tcells, which can recruit things to attack it.

So this is the autoimmunecomponent of the disease. This HLAB27 associationactually exists for the seronegativespondyloarthropathies in general, but here, in particular, for AS you should remember that connection. And then, just a littlebackground information on the group of peoplethat tend to get this. Remember, nothing is absolute,

but if we're looking for patterns, it's going to be malesand relatively young ones, actually, really young ones, from 15 to 45 is going to be the meanor the biggest group of people who get AS or that'swhen it's diagnosed the most. So the name kind of tells us what symptoms are characteristic. We have this fusion of the spine.
