Study Notes

Gout Treatment

Gout is a metabolic disease where urate crystals deposit in tissues, causing extremely painful intermittent attacks of acute arthritis. An inflammatory response is triggered.
Historically, gout was associated with wealth, power, and indulgence due to diets rich in purines (found in red meat, seafood, and alcohol). These break down into uric acid, and high levels lead to gout.
Examples of historical figures who suffered from gout include King Henry VIII of England and Louis XIV of France.

Drug Actions in Gout Treatment

Decreasing uric acid synthesis: Allopurinol (primary prophylactic drug), or febuxostat, reduce uric acid creation.
Increasing uric acid excretion: Probenecid, sulfinpyrazone, are uricosuric agents increasing uric acid removal.
Inhibiting leukocyte migration: Colchicine inhibits white blood cell migration into the joint.
Blocking IL-1: Anakinra blocks the inflammatory cytokine IL-1.
General anti-inflammatory and analgesic effect: NSAIDs and occasionally glucocorticoids offer broader pain relief and inflammation reduction.

Stages of Gout Progression

High Uric Acid: No symptoms.
Acute Flares: Symptoms include pain and inflammation in a joint.
Intercritical Periods: No symptoms.
Advanced Gout: Ongoing, potentially severe, joint pain, swellings (tophi).

Allopurinol Treatment

Mechanism of action: Competitive inhibition of xanthine oxidase, reducing uric acid synthesis.
Biochemical effects: Reduces insoluble urate and uric acid in tissues, plasma, and urine. Increases the precursor xanthines and hypoxanthines, which are more soluble.
Important note: Avoid starting during an acute attack. It can worsen symptoms. Often combined with NSAIDs or colchicine during initial treatment of chronic gout.
Adverse Reactions (ADRs): Gastrointestinal disturbances, rash, blood alterations.
Interactions: May increase the effectiveness of some chemotherapy agents.

Uricosuric Agents

Mechanism of action: Increase uric acid excretion by directly acting on the renal tubules.
Use: Probenecid, Sulfinpyrazone, and Benzbromarone
Important Note: initiate treatment with an NSAID.
Probenecid/Sulfinpyrazone: Useful for prophylaxis in severe recurrent gout with adverse reactions to allopurinol.
Benzbromarone: Use limited to patients with renal impairment.

Uricolytic Agents (Rasburicase)

Action: A preparation containing the enzyme uric acid oxidase.
Function: Breaks down uric acid into allantoin (more soluble and easily excreted by the kidneys).
Use: For aggressive treatment of gout, prophylaxis for chemotherapy-induced hyperuricemia.

Colchicine Treatment

Mechanism of action: Prevents and relieves acute gout attacks. It inhibits neutrophil migration into the joint.
At higher doses: Potential to inhibit mitosis, leading to bone marrow depression (anticancer).
Adverse Reactions (ADRs): Nausea, vomiting, abdominal pain, severe diarrhea, gastrointestinal hemorrhage, kidney damage, bone marrow depression, and peripheral neuropathy.

Corticosteroids

Action: Systemically or intraarticularly to treat acute gout flares when other treatment options aren't possible.
Example: Prednisone (dosage 30-40mg/day) until symptom improvement (within 2 to5 days)

Novel Therapies (Anakinra, Canakinumab, etc)

Action: These target inflammatory cytokines (IL-1ß). Other IL-1 family members also play a role in gout.
Example: Anakinra, a form of anti-IL-1ẞ therapy, plays a key role in gout as an inflammatory mediator.

Non-Pharmacological Interventions

Diet: Low in purine-rich foods, avoid high-fructose corn syrup, limit alcohol.
Weight Management: Weight loss and exercise to reduce serum uric acid (UA) levels.
Topical Ice: Reduce pain and inflammation during flares.

Clinical Uses

Acute Gout: NSAIDs (ibuprofen, naproxen), colchicine, glucocorticoids used to target inflammatory phase.
Prophylaxis: Allopurinol (after acute phase resolves) then urate-lowering therapy, uricosuric drugs or Rasburicase.
