Spondyloarthritis is a group of inflammatory diseases that cause arthritis. You also may hear it called spondyloarthropathy or, for short, Spondyloarthritis.
Spondyloarthritis tends to be inherited.
Scientists have linked about 30 genes to the condition.
The biggest culprit is one called HLA-B27.
It’s found in 90% of people who have the most common form of spondyloarthritis (ankylosing spondylitis).
But not everyone who has the gene gets it.
Ankylosing spondylitis (also called ‘spondylitis’)
This is the most common form. It affects the joints and ligaments along your spine and causes pain and stiffness that start in your lower back and may spread into your upper spine, chest, and neck. Eventually, the joints and bones there can fuse and make your spine stiffen into a C-shape. That leads to a hunched posture.
This starts with an infection of your intestine or urinary tract. An immune reaction may follow that can cause pinkeye (conjunctivitis) and can cause rash oral ulcers and urinary tract inflammation as well as arthritis. This condition used to be known as Reiter’s syndrome.
Some people who have the skin disease psoriasis also get this type of arthritis. With it, your body’s immune system attacks healthy joints and skin by mistake. That can cause joint pain, stiffness, and swelling in your hands and feet as well as the spine.
This inflammatory arthritis affects some part of your digestive tract. It can be associated with a number of inflammatory bowel diseases, including Crohn’s disease and ulcerative colitis.
Inflammation of the aortic heart valve
Pain or swelling in other joints, including your hips, knees, ankles, feet, hands, wrists, elbows, and shoulders
Psoriasis skin rash
Swelling along the tendons of your fingers or toes (“sausage fingers”)
Swelling, pain, or redness in part of an eye
To find out if you have spondyloarthritis, your doctor will do a complete physical exam and look at your medical history.
They may want to take X-rays of your spine and a pair of joints in your pelvis called the sacroiliac joints to look for changes.
You also may need an MRI (magnetic resonance imaging), which uses powerful magnets and radio waves to get a clearer look at your joints.
Your doctor may want to do a blood test to see if you carry the HLA-B27 gene. The test can help confirm diagnosis.
Nonsteroidal anti-inflammatory drugs.
NSAIDs like ibuprofen, indomethacin (Tivorbex), meloxicam (Mobic), and naproxen (Aleve, Anaprox, Naprosin) can help with your symptoms.
Shots in your joints or in the membrane around your tendon can work quickly. This option works best if your joint swelling is in one specific area.
If you have reactive arthritis, which begins with a bacterial infection, antibiotics can help, at least at first.
Disease-modifying antirheumatic drugs.
DMARDs such as methotrexate and sulfasalazine (Azulfidine) work best if you have arthritis that affects the joints in your arms and legs. Your doctor may prescribe these to help your symptoms and prevent joint damage.
Mononuclear antibodies are used to stimulate the body’s own immune system to help fight the disease. Ixekizumab (Taltz) has recently been approved to help prevent the inflammation. Tumor necrosis alpha (TNF-alpha) blockers. This newer class of drugs, known as biologics, can treat arthritis in both the spine and joints.
Over time, inflammation can damage the cartilage in your hips, causing pain and problems with movement. In that case, you may need a hip replacement. In rare cases, you might need spinal surgery.⌖ diseases treatments health prevention disorders spondyloarthritis skeletal-system
