Clinical Causes: Use of medications that increase uric acid levels, such as diuretics (e.g., thiazides), low-dose aspirin, or immunosuppressive drugs. Prolonged use or high doses of these medications leading to uric acid buildup. Pre-existing risk factors like obesity, high purine diet, or kidney impairment enhancing susceptibility. Genetic predisposition affecting uric acid metabolism.

Key Symptoms: Persistent swelling, redness, and warmth in the affected joint, especially the right hand. Chronic joint pain that worsens over time. Formation of tophi (urate crystal deposits) that may be visible or palpable around the joints. Limited range of motion or stiffness of the fingers and hand. Recurring flare-ups that can become more frequent and severe.

Diagnosis Path: A detailed patient history focusing on medication use and symptom onset. Physical examination to assess joint inflammation and damage. Blood tests to measure serum uric acid levels, which are often elevated. Joint aspiration and fluid analysis to identify monosodium urate crystals under microscopy. Imaging studies such as X-rays may reveal joint damage or tophi formation characteristic of chronic gout.

Treatment Protocols: Adjusting or discontinuing medications that contribute to increased uric acid levels, in consultation with a healthcare provider. Use of anti-inflammatory drugs such as colchicine or NSAIDs to control acute flare-ups. Chronic management with urate-lowering therapies like allopurinol or febuxostat to reduce serum uric acid levels. Lifestyle modifications including maintaining a healthy weight, adhering to a low-purine diet, limiting alcohol intake, and staying well-hydrated. Regular monitoring of uric acid levels to prevent flare-ups and joint damage. In cases of significant joint damage or tophi, surgical interventions might be considered.
