Overview of Psoriatic Arthritis
Psoriatic arthritis is a type of inflammatory arthritis that occurs in people with the skin condition psoriasis. It is an autoimmune disease, which means the body's immune system mistakenly attacks healthy cells and tissues. The exact cause of psoriatic arthritis is unknown, but genetics and environmental factors play a role in its development.
Common Symptoms of Psoriatic Arthritis
Psoriatic arthritis can affect any joint in the body, but commonly involves the fingers, toes, lower back, and joints in the feet. The symptoms may vary from person to person, but common signs include joint pain, swelling, stiffness, and redness. Other symptoms that may occur in psoriatic arthritis include fatigue, nail changes, eye problems, and skin rashes.
Diagnosis of Psoriatic Arthritis
Diagnosing psoriatic arthritis involves a thorough physical examination, medical history review, and imaging tests such as X-rays and MRIs. Blood tests may also be conducted to check for specific markers associated with inflammation and autoimmune diseases. A dermatologist or rheumatologist may be involved in the diagnosis and treatment of psoriatic arthritis.
Treatment and Management of Psoriatic Arthritis
Treatment for psoriatic arthritis aims to reduce inflammation, manage pain, and prevent joint damage. Medications such as nonsteroidal anti-inflammatory drugs (NSAIDs), disease-modifying antirheumatic drugs (DMARDs), and biologics may be prescribed. Physical therapy, lifestyle modifications, and surgery may also be recommended to improve joint function and quality of life.
