Understanding the Connection Between Psoriasis and Psoriatic Arthritis

If you’re living with psoriasis, you may wonder if you’re at risk of developing psoriatic arthritis (PsA). The truth is, the exact link between these two conditions is still being researched. However, understanding the relationship between them can help you take proactive steps to manage your health.

The Prevalence of Psoriasis and Psoriatic Arthritis

Psoriasis affects approximately 2-3% of the global population, with around 7.5-8 million people in the United States living with the condition. Of those, about 1 in 3 may develop PsA, which involves inflammatory arthritis along with skin psoriasis. The exact number of people who develop PsA varies depending on the study, but experts estimate it to be around 30%.

Risk Factors for Developing Psoriatic Arthritis

Several factors can increase your risk of developing PsA, including:

• Living with psoriasis
• Family history of PsA or psoriasis
• Certain genetic mutations, such as the HLA-B gene
• Smoking or having been a smoker in the past
• Drinking alcohol
• Environmental factors, such as infections, living with HIV, stress, or stressful life events
• Age, with most people developing PsA between 30 and 50
• Body size, with up to 50% of people who develop PsA having obesity

Early Signs of Psoriatic Arthritis

If you’re developing PsA, your symptoms may start mild and gradually increase, or they may develop suddenly. Common symptoms include:

• Fatigue
• Stiffness and tiredness in the morning
• Swelling, pain, and tenderness in the tendons
• Swollen “sausage-like” fingers or toes
• Changes in your nails, such as pitting
• Pain and redness in one or both eyes
• Reduced range of motion in one or more joints

The Importance of Early Detection

Catching PsA early is crucial to prevent joint damage. Regular dermatology appointments and alerting your dermatologist to any joint pain or swelling can help identify PsA in its early stages.

Prevention and Treatment

While there is no way to prevent PsA, researchers are working to understand how psoriasis transitions to PsA. In the meantime, managing your psoriasis symptoms and adopting a healthy lifestyle can help reduce the impact of PsA. Common treatments for both psoriasis and PsA include topical preparations, NSAIDs, corticosteroids, DMARDs, biologics, and lifestyle interventions.

Take Control of Your Health

Living with psoriasis increases your risk of developing PsA, but by understanding the risk factors and early signs, you can take proactive steps to manage your health. Work with your doctor or treatment team to monitor for PsA and develop a plan to address any concerns you may have.
