If you have been diagnosed with psoriatic arthritis, you are not alone. This chronic autoimmune condition affects approximately 15% of people with psoriasis.

Psoriatic arthritis can cause joint pain, stiffness, and swelling, and if left untreated, can lead to permanent joint damage and disability. However, with proper treatment and self-care, many people with psoriatic arthritis can manage their symptoms and lead fulfilling lives. This handbook offers practical information and tips to help you understand and manage your psoriatic arthritis.

What is psoriatic arthritis?

Psoriatic arthritis (PsA) is a chronic inflammatory condition that affects joints and connective tissues. It typically develops in people who have psoriasis, a skin condition that causes red, scaly patches on the skin.

However, some people may develop PsA without having psoriasis. PsA can affect any joint in the body, but most commonly affects the fingers, toes, spine, and pelvis.

What causes psoriatic arthritis?

The exact cause of PsA is unknown, but it is believed to be an autoimmune condition, in which the body’s immune system mistakenly attacks healthy tissues. There may also be genetic factors that contribute to the development of PsA.

What are the symptoms of psoriatic arthritis?

PsA can cause a range of symptoms, which can vary in severity and may flare up periodically. Common symptoms include:.

Joint pain and stiffness
Swelling and tenderness at the joints
Reduced range of motion
Fatigue
Eye inflammation (uveitis or iritis)
Skin changes or rashes

How is psoriatic arthritis diagnosed?

PsA can be difficult to diagnose, as its symptoms can resemble those of other types of arthritis. To diagnose PsA, your doctor may perform a physical exam, review your medical history, and order imaging or blood tests to look for signs of inflammation.

You may also be referred to a rheumatologist, a specialist in autoimmune disorders, for further evaluation and treatment.

How is psoriatic arthritis treated?

Treatment for PsA will depend on the severity of your symptoms and the extent of joint damage.

Your doctor may recommend a combination of medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs), disease-modifying antirheumatic drugs (DMARDs), or biologic therapies, which target specific molecules in the immune system. Physical therapy and exercise can also help improve joint function and reduce pain. In addition, self-care measures such as maintaining a healthy weight, minimizing stress, and protecting your joints from injury can help manage PsA symptoms.

Can psoriatic arthritis be prevented?

There is no known way to prevent PsA, but some lifestyle changes may help reduce the risk or severity of symptoms. These include:.

Maintaining a healthy weight
Eating a well-balanced diet
Avoiding smoking and excessive alcohol consumption
Minimizing stress
Protecting your skin from injury or sun damage

Living with psoriatic arthritis

Managing PsA can be challenging, but with the right treatment and self-care, many people can lead active and productive lives. It is important to work closely with your healthcare team to develop a treatment plan that best meets your individual needs.

Additionally, support groups and education programs can provide valuable resources and information to help cope with PsA and maintain a positive outlook.
