A 32-year-old man who is HIV-positive was found to have Burkitt's lymphoma with diffuse bulky abdominal disease. He now reports to the hospital and is scheduled to begin chemotherapy. Admission laboratory studies show elevations of his uric acid at 15 mg/dL, serum phosphorus at 8.5 mg/dL, creatinine at 2.9 mg/ dL, and potassium at 6.1 mEq/L.
What therapy is most likely to reverse the patient's metabolic abnormalities?
