Psoriatic arthritis (PsA) is a chronic autoimmune condition that affects the joints, skin, and nails. It is a form of inflammatory arthritis that is closely associated with psoriasis, a common skin condition. PsA can develop at any age, but it is most commonly seen in adults in their 30s and 40s.
Risk Factors for Developing Psoriatic Arthritis
People who have psoriasis are more likely to develop PsA than those without psoriasis. Other factors that increase the risk of PsA include being overweight, smoking, and having a family history of the condition.
Symptoms of Psoriatic Arthritis
The most common symptoms of PsA are joint pain, swelling, and stiffness. Other symptoms may include fatigue, nail changes, and skin rashes. In severe cases, PsA may cause deformity of the affected joints.
Diagnosis and Treatment of Psoriatic Arthritis
PsA is diagnosed based on a physical exam, medical history, and lab tests. Treatment of PsA typically involves the use of medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs), disease-modifying antirheumatic drugs (DMARDs), and biologic drugs. In some cases, lifestyle changes, such as exercise and weight loss, may also be recommended.
