Ankylosing Spondylitis (cont.)
What are treatment options for ankylosing
spondylitis?
The treatment of ankylosing spondylitis typically involves
the use of medications to reduce inflammation and/or suppress immunity to stop progression of the disease,
physical therapy, and exercise. Medications decrease inflammation
in the spine and other joints and organs. Physical therapy and
exercise help improve posture, spine mobility, and lung capacity.
Aspirin and other nonsteroidal anti-inflammatory drugs
(NSAIDs) are commonly used to decrease pain and stiffness of the
spine and other joints. Commonly used NSAIDs include indomethacin
(Indocin), tolmetin (Tolectin),
sulindac (Clinoril), naproxen
(Naprosyn), and diclofenac (Voltaren). Their common
side effects include stomach upset, nausea, abdominal pain, diarrhea, and even
bleeding ulcers. These medicines are frequently taken with food
in order to minimize side effects.
In some people with ankylosing spondylitis,
inflammation
of joints excluding the spine (such as the hips, knees, or ankles) becomes the major problem. Inflammation in these joints may not respond to NSAIDs alone.
For these individuals, the addition of medications that suppress the body's immune system
is considered. These medications, such as sulfasalazine (Azulfidine),
may bring about long-term reduction of inflammation. An alternative to sulfasalazine that is somewhat more effective is methotrexate (Rheumatrex, Trexall), which can be administered
orally or by injection. Frequent blood tests are performed during
methotrexate treatment because of its potential for toxicity to
the liver, which can even lead to cirrhosis, and toxicity to bone
marrow, which can lead to severe anemia.
Recent research has shown that for persistent ankylosing spondylitis with spinal involvement that is unresponsive to anti-inflammatory medications, both sulfasalazine and methotrexate are ineffective. Newer, effective medications for spine disease attack a messenger protein of inflammation called tumor necrosis factor
(TNF). These TNF-blocking medications have been shown to be extremely effective for treating ankylosing spondylitis by stopping disease activity, decreasing inflammation, and improving spinal mobility. Examples of these TNF-blockers include etanercept (Enbrel), infliximab (Remicade), adalimumab (Humira), and golimumab (Simponi).
Several major points about the treatment of ankylosing spondylitis deserve emphasis. There is an early, underdiagnosed stage of
spondylitis that occurs before plain X-ray testing can detect classic changes.
Patients who are treated earlier respond better to treatments. Current
disease-modifying drugs such as methotrexate, sulfasalazine, and leflunomide (Arava), which can
be effective for joint inflammation of joints away from the spine, are not
effective for spinal inflammation. If nonsteroidal anti-inflammatory drugs
(NSAIDs) are not effective in a patient whose condition is dominated by spinal
inflammation (and 50% do respond), then biologic medications that inhibit tumor necrosis factor (TNF
inhibitors) are indicated. All TNF inhibitors, including Remicade, Enbrel, Humira, and Simponi are effective in treating ankylosing spondylitis. The improvement that results for TNF inhibition is sustained during years of treatment. If the TNF inhibitors are discontinued, for whatever reason, relapse of disease occurs in virtually all patients
within a year. If TNF inhibitor is then resumed, it is typically effective.
Oral or injectable corticosteroids (cortisone) are
potent anti-inflammatory agents and can effectively control
spondylitis and other inflammations in the body. Unfortunately, corticosteroids
can have serious side effects when used on a long-term basis.
These side effects include cataracts, thinning of the skin and
bones, easy bruising, infections, diabetes, and destruction of
large joints, such as the hips.
Physical therapy for ankylosing spondylitis includes instructions and exercises to
maintain proper posture. This includes deep breathing for lung expansion and
stretching exercises to improve spine and joint mobility. Since ankylosis of the
spine tends to cause forward curvature, patients are instructed to maintain
erect posture as much as possible and to perform back-extension exercises.
Patients are also advised to sleep on a firm mattress
and avoid the use of a pillow in order to prevent spine curvature.
Ankylosing spondylitis can involve the areas where the ribs attach
to the upper spine as well as the vertebral joints, thus limiting
breathing capacity. Patients are instructed to maximally
expand their chest frequently throughout each day to minimize
this limitation.
Exercise programs are customized for each individual. Swimming
often is a preferred form of exercise, as it avoids jarring impact of
the spine. Ankylosing spondylitis need not limit an individual's
involvement in athletics. People can participate in carefully chosen aerobic
sports when their disease is inactive. Aerobic exercise is generally encouraged as it promotes full
expansion of the breathing muscles and opens the airways of the lungs.
Inflammation and diseases in other organs are treated
separately. For example, inflammation of the iris of the eyes (iritis or uveitis) may require cortisone eyedrops (Pred
Forte)
and high doses of cortisone by mouth. Additionally, atropine eyedrops are often given to relax the muscles of the iris. Sometimes injections of cortisone into the affected eye are necessary when the inflammation
is severe. Heart disease in patients with ankylosing spondylitis, such as heart
block,
may require a pacemaker placement or medications for congestive
heart failure.
Cigarette smoking is strongly discouraged in people
with ankylosing spondylitis, as it can accelerate lung scarring
and seriously aggravate breathing difficulties. Occasionally,
those with severe lung disease related to ankylosing spondylitis
may require oxygen supplementation and medications to improve
breathing.
People with ankylosing spondylitis may need to modify their activities of daily living and adjust features of the workplace. For example, workers can adjust chairs and desks for proper postures. Drivers can use wide rearview mirrors and prism glasses to compensate for the limited motion in the spine.
Finally, orthopedic surgery maybe required when there is severe disease of the hip joints and spine.
