A 63-year-old man presents to his primary care provider with colicky pain radiating to his left groin. The pain has been intermittent for several days. He has also been experiencing occasional burning pain in his hands and feet and frequent headaches. His past medical history is significant for an NSTEMI last year. He is currently taking atorvastatin and low dose aspirin. Today his temperature is 36.8°C (98.2°F), the heart rate is 103/min, the respiratory rate is 15/min, the blood pressure 135/85 mm Hg, and the oxygen saturation is 100% on room air. On physical exam, he appears gaunt and anxious. His heart is tachycardia with a regular rhythm and his lungs are clear to auscultation bilaterally. On abdominal exam he has hepatomegaly. A thorough blood analysis reveals a hemoglobin of 22 mg/dL and a significantly reduced EPO. Renal function and serum electrolytes are within normal limits. A urinalysis is positive for blood. A non-contrast CT shows a large kidney stone obstructing the left ureter. The patient’s pain is managed with acetaminophen and the stone passes with adequate hydration. It is sent to pathology for analysis. Additionally, a bone marrow biopsy is performed which reveals trilineage hematopoiesis and hypercellularity with a JAK2 mutation. Which medication would help prevent future episodes of nephrolithiasis?
