Clinical Causes: Certain medications that increase uric acid levels, such as diuretics (water pills), especially thiazides. Medications used in chemotherapy that can cause rapid cell turnover, raising uric acid production. Immunosuppressants used after organ transplants or for autoimmune diseases. Nicotinic acid (nicotinic acid or niacin) therapy for cholesterol management. Other drugs that interfere with uric acid excretion or increase its production.

Key Symptoms: Sudden and intense pain in the ankle or foot joints. Redness and swelling around the affected joint. Warmth and tenderness usually accompany the pain. Limited range of motion in the affected joint. Typically, symptoms develop rapidly and may wake individuals during sleep. Recurrent episodes can occur if the underlying cause persists.

Diagnosis Path: Diagnosis often involves a combination of clinical evaluation, medical history, and laboratory tests. A healthcare provider may perform blood tests to measure uric acid levels. Joint aspiration, where fluid is extracted from the affected joint, can reveal urate crystals under a microscope, confirming gout. Imaging studies, such as X-rays, can help assess joint damage or rule out other causes of joint pain. Recognizing medication history as a cause is essential.

Treatment Protocols: Discontinuing or changing the medication responsible for increasing uric acid levels, under medical supervision. Use of anti-inflammatory medications like NSAIDs to reduce pain and inflammation. Colchicine, a medication specifically used for gout attacks, may be prescribed. Corticosteroids may be given orally or injected into the joint to control inflammation. Lifestyle modifications, such as dietary changes to lower purine intake, can help prevent future episodes. Monitoring uric acid levels regularly to manage and prevent recurrent gout attacks.
