Levels of C-Reactive Protein in Patients with Hematologic Malignancies

Abstract
The levels of C-reactive protein (CRP) were assayed in 282 serial sera of 70 patients with hematologic malignancies who were under antineoplastic medication, and surveyed with frequent blood cultures. The mean peak value of CRP in febrile patients with bacteriologically verified sepsis was 162 mg/l and differed significantly (p < 0.001) from that (23 mg/l) of afebrile patients with negative blood cultures, but not from that (115 mg/l) of febrile patients without confirmed bacteremia. All the values in afebrile patients with negative blood cultures were < 100 mg/l; 71% of their peak values were < 40 mg/l. Thus the malignancy itself or its treatment did not considerably mount CRP response.
