Difficulty: EasyPharmacologic Interventions

A 67-year-old man presents to the clinic with excruciating pain, redness, and swelling in his right great toe that started abruptly yesterday. The pain is severe enough that he cannot tolerate the touch of a bedsheet or wear a regular shoe. His past medical history is significant for type 2 diabetes mellitus, hypertension, coronary artery disease, and stage 4 chronic kidney disease. His most recent laboratory studies from two weeks ago showed a serum creatinine of 3.2 mg/dL and an estimated glomerular filtration rate (eGFR) of 20 mL/min/1.73 m². Vital signs are temperature 37.1°C (98.8°F), blood pressure 152/90 mm Hg, and heart rate 88/min. Physical examination reveals an erythematous, warm, and exquisitely tender right first metatarsophalangeal joint. The clinical picture is highly consistent with an acute gout flare. Which of the following is the most appropriate pharmacologic intervention for this patient?

  1. Oral prednisoneAnswer
  2. B
    Oral indomethacin
  3. C
    Oral colchicine
  4. D
    Oral allopurinol
  5. E
    Intravenous ceftriaxone

Answer

Oral prednisone
The correct intervention is oral prednisone. The management of acute gout flares relies on three primary pharmacologic options: nonsteroidal anti-inflammatory drugs (NSAIDs), colchicine, or glucocorticoids (systemic or intra-articular). In patients with advanced chronic kidney disease (eGFR < 30 mL/min/1.73 m²), NSAIDs are absolutely contraindicated due to the high risk of precipitating acute renal failure. Colchicine is also heavily dependent on renal clearance and is generally avoided in severe renal impairment due to the risk of life-threatening bone marrow suppression and neuromyopathy. Therefore, systemic glucocorticoids such as oral prednisone are the safest and most appropriate first-line choice for acute flare stabilization in this patient.

Step-by-Step Solution

1
Identify the primary clinical problem requiring acute management.
The patient is experiencing an acute gout flare in the right first metatarsophalangeal joint (podagra).
The history of abrupt, severe monoarticular joint pain with erythema and swelling in the great toe is the classic presentation of acute gout.
2
Evaluate patient-specific comorbidities that influence pharmacologic choices.
The patient has stage 4 chronic kidney disease with an eGFR of 20 mL/min/1.73 m².
Standard first-line treatments for gout must be filtered through the patient's renal function to avoid severe iatrogenic complications.
3
Select the safest and most effective first-line anti-inflammatory medication.
Oral prednisone (or intra-articular glucocorticoids) is chosen.
Glucocorticoids do not rely on renal clearance and do not cause acute nephrotoxicity, making them the safest choice when NSAIDs and colchicine are contraindicated by severe renal impairment.
