A 40-year-old obese man presents with intense pain in his left first metatarsophalangeal (MTP) joint for the past few hours. He has no history of trauma, fever, chills, and no previous similar episode. He has no history of renal disease or diabetes though he has been told he is “prediabetic.” He does not recall any recent skin infections and no family members have had any reported staphylococcal infection. On examination he has a swollen, red, warm, tender first MTP joint on the left. Uric acid level is 9 mg/dL; serum creatinine is normal. What is the best treatment approach for this patient?

💡 Explanation
**Core Concept**
The patient's presentation of acute monoarthritis, particularly involving the first metatarsophalangeal (MTP) joint, in the absence of trauma, fever, or previous episodes, raises suspicion for acute gouty arthritis. Gout is a form of inflammatory arthritis characterized by the deposition of monosodium urate crystals within the joint space, often triggered by hyperuricemia.
**Why the Correct Answer is Right**
The patient's elevated uric acid level (9 mg/dL) and acute presentation of joint inflammation are consistent with acute gouty arthritis. The first MTP joint is a common site for gouty attacks due to its high concentration of urate crystals. The absence of renal disease or diabetes as underlying causes of hyperuricemia makes this diagnosis more likely. The correct treatment approach involves the use of anti-inflammatory medications to reduce inflammation and alleviate pain.
**Why Each Wrong Option is Incorrect**
**Option A:** Corticosteroids may be used in certain cases of gout, but they are not the first-line treatment for acute gouty arthritis. In this scenario, NSAIDs or colchicine would be more appropriate initial choices.
**Option B:** Methotrexate is used in the treatment of rheumatoid arthritis, not acute gouty arthritis.
**Option C:** Hydroxychloroquine is used in the treatment of systemic lupus erythematosus and rheumatoid arthritis, not acute gouty arthritis.
**Option D:** Allopurinol is a urate-lowering therapy used in the long-term management of gout, but it is not the best initial treatment approach for acute gouty arthritis.
**Clinical Pearl / High-Yield Fact**
In the emergency management of acute gouty arthritis, NSAIDs (e.g., indomethacin, ibuprofen) or colchicine are preferred initial treatments due to their rapid onset of action and effectiveness in reducing inflammation and pain.
**Correct Answer:** C. Colchicine is the best initial treatment approach for this patient, given the acute presentation of gouty arthritis and the need for rapid reduction of inflammation and pain.
✓ Correct Answer: C. Begin indomethacin. As the patient improves, reduce the dose to minimize gastrointestinal side effects.
