Clinical Causes: Genetic predisposition: Family history of psoriasis or psoriatic arthritis increases risk. Autoimmune response: The body's immune system mistakenly attacks healthy joint tissues. Environmental triggers: Factors such as infections, stress, or skin trauma may contribute. Presence of psoriasis: The condition typically develops in individuals already diagnosed with psoriasis. Possible influence of lifestyle factors: Smoking and obesity may aggravate disease progression.

Key Symptoms: Severe joint pain and swelling, often in the fingers and toes. Progressive joint deformity leading to mutilation of affected areas. Reduced joint mobility and stiffness, especially after periods of inactivity. Tenderness around the joints and areas of inflammation. Nail changes such as pitting or onycholysis associated with psoriatic disease. Fatigue and general malaise in some cases. Potential skin involvement with psoriatic plaques.

Diagnosis Path: Reviewing patient's history of psoriasis and joint symptoms. Physical assessment of joint deformities and swelling. Imaging studies such as X-rays, MRI, or ultrasound to evaluate joint damage and erosion. Blood tests to rule out other types of arthritis and check for inflammatory markers (e.g., ESR, CRP). Assessment of skin lesions consistent with psoriasis.

Treatment Protocols: Nonsteroidal anti-inflammatory drugs (NSAIDs) to reduce pain and inflammation. Disease-modifying antirheumatic drugs (DMARDs) such as methotrexate to slow disease progression. Biologic agents targeting specific immune pathways, including TNF inhibitors, IL-17 inhibitors, and IL-12/23 inhibitors. Corticosteroids for short-term relief of severe inflammation. Physical therapy and occupational therapy to maintain joint function and mobility. Surgical interventions may be necessary in cases of severe joint destruction, including joint replacements or reconstructive surgeries. Lifestyle modifications such as smoking cessation, weight management, and skin care to minimize triggers.
