Spondylitis is the
name for a specific type of inflammatory arthritis that causes mostly affects
the spine, though other joints may become affected as well. There are several
specific diseases in the spondylitis “family”, including; Ankylosing
spondylitis (AS), undifferentiated spondyloarthopathy (USpA) a condition which
advances over time to AS or another kind of arthritis, juvenile
spondyloarthropathy (JSpA) with onset before the age of 16, psoriatic arthritis
(PsA) which is preceded by psoriasis, and reactive arthritis (ReA) which is
thought to derive as a ‘reaction’ to an infection elsewhere.
The specific causes of spondylitis
is unknown, but there are very strong links to the genetic marker HLA-B27,
found in about 8% of the general population. Though the gene has not proven to
cause spondylitis by itself, it has been found that HLA-B27+ individuals are at
an increased risk to develop the condition. Over 95% of European people with spondylitis
ancestry express HBL-B27, but an environmental ‘trigger’ is typically required
to kick start the condition, like a bacterial infection.
The condition is diagnosed,
typically by a rheumatologist, through a thorough physical exam, including
x-ray, individual medical history, family history, and bloodwork with possible
HLA-B27 screening. There are key points to consider for diagnosis, these
include onset usually under the age of 45, chronic pain for more than 3 months,
pain worsen with mobility, especially at night and early morning, stiffness
tends to ease with physical activity, and a positive pain/stiffness relieving
response no non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen. The doctor
examines the back, pelvic bones, sacroiliac bones, chest and heels for
tenderness and pain. Also limitation of spinal mobility in all directions may
be assessed as well as chest expansion limitations when breathing.
A cure for spondylitis has not been
found yet, but treatment has drastically increased quality of life through exercise,
physical therapy, medication, and posture changes. Helpful exercises include
water therapy, tai chi, and things as simple as walking. One of the problems
with spondylitis is bone fusion, which doesn’t always happen, but it is highly preferable
to observe good posture and allow fusion in an upright position to avoid further
complications. While pinpointing the causes is still a work in progress in the scientific world, individuals who suffer from spondylitis have a lot of pharmaceutical industry support actively looking for a cure, which is in the patient's best interest.
