psoriatic arthritis is an inflammatory arthritis that is associated with psoriasis, a chronic skin condition characterized by red, scaly patches on the skin. Psoriasis affects about 2% of the population, and about 30% of people with psoriasis develop psoriatic arthritis.
Psoriatic arthritis can affect any joint in the body, but most commonly affects the joints of the fingers, toes, spine, and sacroiliac joints (the joints that connect the spine to the pelvis). It is a chronic, progressive disease that can lead to joint damage and disability if left untreated.
The symptoms of psoriatic arthritis include joint pain, swelling, stiffness, and tenderness, as well as skin and nail changes associated with psoriasis. Other symptoms may include fatigue, eye inflammation, and gastrointestinal symptoms.
Treatment for psoriatic arthritis depends on the severity of the disease and may include nonsteroidal anti-inflammatory drugs (NSAIDs), disease-modifying antirheumatic drugs (DMARDs), biologic medications, and physical therapy. Lifestyle modifications, such as exercise and stress reduction, may also be helpful in managing symptoms. Early diagnosis and treatment are important in order to prevent joint damage and disability.
