On presentation, laboratory findings showed leukopenia (3,000/μL; 4,000-11,000/μL) with 37% neutrophils (40-60%), CRP (C-reactive protein) 24 mg/dL (<0.5 mg/dL), worsening renal function with creatinine 2.5 mg/dL (0.6-1.2 mg/dL; baseline 1 mg/dL), and LDH (lactate dehydrogenase) 455 U/L (140-280 U/L), as shown in Table 1. Here, CRP is linked to Decreased total leukocyte count.
