Overview

What is Psoriatic Arthritis?

Psoriatic arthritis is a condition that combines the swollen, sore joints of arthritis with psoriasis. Psoriasis typically causes itchy, scaly red patches to appear on the skin and scalp. There are five types of psoriatic arthritis in which your doctor will help diagnose. These include:

Symmetric psoriatic arthritis

Asymmetric psoriatic arthritis

Distal interphalangeal psoriatic arthritis

Spondylitis psoriatic arthritis

Psoriatic arthritis mutilins

What are the signs of Psoriatic Arthritis?

Symptoms of psoriatic arthritis are different for each person. They can be mild to severe. Sometimes your condition will go into remission and you’ll feel better for a while. Other times your symptoms may get worse. Your symptoms also depend on the type of psoriatic arthritis you have.

Causes

What are the causes of Psoriatic Arthritis?

Doctors are unclear of the direct cause of psoriasis. However, research shows two key factors that play a role: genetics and the immune system. Psoriasis is an autoimmune condition. Autoimmune conditions are the result of the body attacking itself. In the case of psoriasis, white blood cells known as T cells mistakenly attack the skin cells.

Some people inherit genes that make them more likely to develop psoriasis. If you have an immediate family member with psoriasis, your risk for developing it is higher.

Diagnosis

How do I know if I have Psoriatic Arthritis?

If you have symptoms of psoriasis, your doctor or dermatologist can make a diagnosis by examining your skin. If your symptoms are unclear, your doctor may take a biopsy of the skin for more detailed examination. Your doctor will identify the types of lesions and their severity to determine the best treatment. They may also request the following tests:

Allergy panel IgA, IgE, IgG and inhalants (blood)
