Psoriatic Arthritis causes pain and inflammation in joints in people with psoriasis.

In most people, psoriatic arthritis occurs approximately 10 years after the onset of psoriasis. Dermnet NZ explains that approximately 13-17% of people with psoriasis, end up being diagnosed with psoriatic arthritis.

The 5 Types of Psoriatic Arthritis

There are different types of psoriatic arthritis, such as: 

  • Symmetric psoriatic arthritis where symptoms affect five or more joints on both sides of the body. Symptoms can be similar to rheumatoid arthritis. More than half of all diagnosed cases are of this type.
  • Distal Psoriatic arthritis causes pain and swelling in hands and feet. Approximately 10% of people with psoriatic arthritis have this type.
  • Asymmetric psoriatic arthritis affects less than five joints
  • Psoriatic arthritis mutilans may deform joints and cause shortening of fingers and toes and can affect the neck and lower back. This type is present in 5% of cases.
  • Spondylitis psoriatic arthritis mainly involves your spine. This type can cause weakness and swelling in the wrists, knees, hands, feet, hands and hips. Can cause back pain and stiffness.

What causes psoriatic arthritis?

In short, doctors don’t know exactly what causes people to develop psoriatic arthritis. We do know that in psoriatic arthritis, your immune system sees your skin and joints as a threat and starts to attack them.

It is thought that it is a combination of genetics, immune system and environmental factors. There are particular triggers that may cause the development of psoriatic arthritis, those include trauma, injury, excessive stress and viral infection.

Risk factors for psoriatic arthritis

  • Diagnosis of psoriasis
  • You have a family member with psoriatic arthritis
  • Had a viral illness such as strep throat

How is it diagnosed?

Your doctor will do an assessment based on a physical assessment and your symptoms.

Your doctor may order blood tests, which may rule out other types of arthritis, such as rheumatoid arthritis.

If your doctor suspects you have psoriatic arthritis, he will refer you to a specialist doctor such as rheumatologist for further investigations and a management/ treatment plan.

What are the complications of psoriatic arthritis?

Having psoriatic arthritis can increase the risk of further health complications. People may have increased risk of:

  • Depression
  • Fatty liver disease

My experience with psoriatic arthritis

From my experience, some people with long term psoriasis have no knowledge of psoriatic arthritis. I have seen patients with poorly managed psoriasis with accompanying joint pain who just assumed it was osteoarthritis due to age. It’s important to see a rheumatologist if joint pain worsens during flare-ups to ensure yours on the right treatment.
