M1A.3

Clinical Causes: Chronic kidney disease or renal impairment impairs the kidneys' ability to excrete uric acid efficiently. High intake of purine-rich foods, such as red meats, seafood, and alcohol, contribute to elevated uric acid levels. Genetic predispositions affecting uric acid metabolism and excretion. Use of certain medications like diuretics or medications that affect renal function. Obesity and metabolic syndrome which can increase uric acid levels and strain kidney function. Dehydration or reduced fluid intake that hampers uric acid elimination.

Key Symptoms: Repeated episodes of joint pain, especially in the big toe, ankles, knees, or elbows. Persistent swelling, redness, and warmth in affected joints. Formation of tophi—hard deposits of uric acid crystals under the skin, often visible around joints or in soft tissues. Limited joint movement due to swelling and joint damage. Possible development of kidney stones composed of uric acid. Fatigue or feeling unwell during acute flare-ups.

Diagnosis Path: Arthrocentesis (joint fluid analysis) to identify uric acid crystals. Blood tests measuring serum uric acid levels. Imaging studies like X-rays or ultrasound to assess joint damage and tophi. Evaluation of kidney function through blood tests like serum creatinine and glomerular filtration rate (GFR).

Treatment Protocols: Medications to reduce uric acid production, such as allopurinol or febuxostat. Uricosuric agents that increase uric acid excretion via kidneys. Pain relievers during flare-ups, including NSAIDs or colchicine. Lifestyle modifications like adopting a low-purine diet, reducing alcohol intake, and maintaining hydration. Managing underlying kidney problems through appropriate medical interventions and lifestyle changes. Regular monitoring of uric acid levels and kidney function.
