What are the symptoms of psoriatic arthritis?
The psoriasis symptoms may start before or after the arthritis. Psoriasis causes red, scaly rashes and thick, pitted fingernails. About 3 in 20 to 3 in 10 people with psoriasis may develop psoriatic arthritis. Symptoms of psoriatic arthritis may include:
- Inflamed, swollen, and painful joints, often in the fingers and toes
- Deformed joints from chronic inflammation
The symptoms of psoriatic arthritis can look like other health conditions. Make sure to see your healthcare provider for a diagnosis.
How is psoriatic arthritis diagnosed?
Psoriatic arthritis is easier to confirm if you already have psoriasis. If you don’t have the skin symptoms, diagnosis is more difficult. The process starts with a health history and a physical exam. Your healthcare provider will ask about your symptoms. You may have blood tests to check the following:
- Erythrocyte sedimentation rate (ESR or sed rate). This test looks at how quickly red blood cells fall to the bottom of a test tube. When swelling and inflammation are present, the blood’s proteins clump together and become heavier than normal. They fall and settle faster at the bottom of the test tube. The faster the blood cells fall, the more severe the inflammation.
- Uric acid. High blood uric acid levels can be seen in psoriatic arthritis but are not used for diagnosis or monitoring.
- Imaging. X-rays, CT scans, ultrasound, MRI, and skin biopsies may all be used to help diagnosis.
How is psoriatic arthritis treated?
Treatment will depend on your symptoms, age, and general health. It will also depend on the severity of your condition.
Both the skin condition and the joint inflammation are treated. Early diagnosis and treatment helps prevent joint damage. Some medicines used to treat psoriatic arthritis include:
- Nonsteroidal anti-inflammatory medicines (NSAIDs) to ease symptoms
- Corticosteroids for inflammation
- Immunosuppressive medicines such as methotrexate to reduce inflammation if NSAIDs don't work
- Biologic medicines to ease inflammation
- Vitamins and minerals such as calcium and vitamin D to slow bone deformation
