case_images: Temporal relationship between hemoglobin (g/dL) and renal function, as represented by creatinine clearance in mL/min, and antibiotic plus steroid use over hospital course. Black points and line represent hemoglobin values on routine checks. Red points and line represent hemoglobin values checked 30 min to 2 h post-transfusion. Patient was transfused 2 units pRBCs on hospital day 9 and 1 unit pRBCs on hospital day 11.

case_images: In total, 3 units pRBCs were transfused during the hospitalization (Fig. 1). Of note, renal function declined primarily after the drop in hemoglobin (Fig. 1). Following cefazolin discontinuation and prednisone initiation, the patient clinically improved with resolution of dark urine and a rise in hemoglobin to 7.3 g/dL prior to discharge on day 24 (see Fig. 1 for trend).
