Summary of Gout - causes, symptoms, diagnosis, treatment, pathology
Gout is an inflammatory disease characterized by the deposition of Monosodium Urate Crystals in joints, leading to symptoms such as redness, heat, tenderness, and swelling, particularly during gouty attacks. The primary cause of Gout is Hyperuricemia, which is an excess of uric acid in the blood, often resulting from the breakdown of Purines found in nucleic acids.
Key Scientific Concepts:
- Hyperuricemia: Elevated levels of uric acid in the blood.
- Monosodium Urate Crystals: Sharp, needle-like crystals formed from uric acid that deposit in joints.
- Purines: Nitrogen-containing compounds that, when metabolized, produce uric acid.
- Inflammation Mechanism: White blood cells migrate to the site of crystal deposition, releasing proinflammatory chemicals.
Causes of Hyperuricemia:
- Increased consumption of purine-rich foods (e.g., shellfish, red meat).
- Increased production of Purines (e.g., from high-fructose corn syrup).
- Decreased clearance of uric acid (e.g., dehydration, alcohol consumption).
- Genetic predisposition to overproduction of uric acid.
- Chronic kidney disease affecting uric acid excretion.
- Certain medications (e.g., thiazide diuretics, aspirin).
Symptoms:
- Severe pain, especially in the first metatarsal joint (podagra).
- Swelling and discomfort that can last for days or weeks.
- Affected joints may include ankles, knees, wrists, and elbows.
Treatment Approaches:
- Pain Management: Nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or naproxen; corticosteroids; Colchicine.
- Lifestyle Modifications: Increased hydration, dietary changes (reducing soda, alcohol, red meat, and seafood), and maintaining physical activity.
- Medications to Lower Uric Acid:
- Xanthine oxidase inhibitors (e.g., Allopurinol) to reduce uric acid production.
- Uricosuric agents (e.g., Probenecid) to enhance uric acid excretion.
Long-Term Complications:
- Chronic Gout can lead to joint tissue destruction, permanent deformity, and tophi (urate crystal deposits).
- Increased risk of kidney stones and urate nephropathy.
