Psoriatic arthritis (PsA) is a chronic autoimmune condition that causes inflammation in the joints and skin. It affects about 1.5 million people in the United States, or 30% of those who have psoriasis, a skin disease characterized by red, scaly patches. While there is no cure for psoriatic arthritis, various treatment options can help manage the symptoms and slow the progression of the disease.
The most common symptoms of psoriatic arthritis include:
Swollen, stiff, and painful joints, particularly in the fingers and toes
Foot pain and lower back pain
Fatigue and morning stiffness
Swelling and pain around tendons
Reduced range of motion
Nail changes, such as pitting or separation from the nail bed
Eye redness and pain (uveitis)
Scaly skin patches, especially on the knees, elbows, and scalp
The exact cause of psoriatic arthritis is unknown, but several factors may play a role, including:
Genetics: Having a family history of psoriasis or psoriatic arthritis increases the risk
Infections: Certain infections, such as strep throat, may trigger the immune system
Physical trauma: Injury to a joint or bone may increase the likelihood of developing PsA
Obesity: Being overweight or obese is a risk factor for both psoriasis and psoriatic arthritis
To diagnose psoriatic arthritis, your doctor will review your medical history, perform a physical examination, and may order imaging tests (X-rays, MRIs, or ultrasounds) and blood tests. Treatment options for psoriatic arthritis include:
Nonsteroidal anti-inflammatory drugs (NSAIDs) to reduce pain and inflammation
Disease-modifying antirheumatic drugs (DMARDs) to slow disease progression
Biologics, which target specific proteins in the immune system to reduce inflammation
Physical and occupational therapy to improve joint function and mobility
Surgery, in severe cases, to replace damaged joints
In addition to medical treatment, lifestyle changes such as maintaining a healthy weight, exercising regularly, and following an anti-inflammatory diet can help manage psoriatic arthritis symptoms. It's also essential to practice stress-reduction techniques and get enough rest to minimize flare-ups.
Psoriatic arthritis is a chronic condition that can significantly impact a person's quality of life. However, with proper treatment and self-care, many people with PsA can manage their symptoms and lead active, fulfilling lives. If you suspect you may have psoriatic arthritis, consult your healthcare provider for an accurate diagnosis and personalized treatment plan.
