Psoriatic Arthritis (PsA) is treated the same way as Ankylosing Spondyloarthritis (AS) except some medications work for Peripheral SpA only.

97% of Psoriatic Arthritis (PsA) patients have Peripheral SpA; only 3% have Axial SpA.

Dermatologists have trouble diagnosing Psoriatic Arthritis (PsA).

Psoriatic Arthritis (PsA) usually starts in the 30s.

Psoriatic Arthritis (PsA) patients don’t have as much axial pain as Ankylosing Spondyloarthritis (AS) patients.

50% of patients with Psoriatic Arthritis (PsA) have sacroiliitis.

There are large numbers of unrecognized disease.

Psoriasis occurs in 3% of the population. One-third of these, or 1% of the population, will also develop PsA.

Ankylosing Spondylitis used to be considered a man’s disease. While recent research shows that men are somewhat more susceptible than women, the exact male to female ratio needs to be clarified.

Peripheral Spondyloarthritis affects joints, nails and skin.

Axial Spondyloarthritis affects the spine and can turn into Ankylosing Spondylitis.

Spondyloarthritis typically starts in young adults but can also affect juveniles.

Spondyloarthritis is an autoimmune disease and a form of inflammatory arthritis.

Osteoarthritis is associated with aging whereas inflammatory arthritis can start in children and frequently occurs in young adults.

Seronegative arthritis is male predominant, except in the case of Psoriatic Arthritis (PsA) where the male to female ratio is 1:1.

Spondyloarthritis is seronegative. That is, a blood test will not show the presence of RF, Rheumatoid Factor.

Rheumatoid Arthritis is seropositive. That is, a blood test shows the presence of RF or Rheumatoid Factor. RF is produced as the immune system attacks healthy tissue.

Not all cases of nrAxSpA turn out to be Ankylosing Spondylitis.

Non-Radiographic Axial Spondyloarthritis or nrAxSpA describes the early symptoms of Ankylosing Spondylitis detected by MRI and other tests where a confirmation of Ankylosing Spondylitis cannot be confirmed by X-Ray.

Axial Spondyloarthritis is a term to describe the possible early stage of Ankylosing Spondylitis, before it can be detected by X-Ray.

Nearly everyone has heard of Rheumatoid Arthritis, a common form of inflammatory arthritis, but hardly anyone has heard of Spondyloarthritis, an inflammatory form of arthritis that is almost as common as Rheumatoid Arthritis.

Inflammatory arthritis covers a number of autoimmune diseases where the body’s own immune system attacks the joints.

Osteoarthritis is caused by the deterioration of cartilage in the joints, often due to wear and tear.

About 4.6 million Canadians live with some form of arthritis.

There are over 100 types of arthritis.

Arthritis can be divided into two sub-groups: osteoarthritis and inflammatory arthritis. Osteoarthritis is far more common than inflammatory arthritis.
