The objective of the study is to examine the assumption that a process of hemolysis plays a role in anemia of acute infection in children. The study was comprised of febrile pediatric patients, who had a positive blood or urine culture. Complete blood count measures were compared between hospitalization and prehospitalization or posthospitalization values. Children admitted to the hospital for elective surgical procedures served as controls. Blood parameters of hemolysis were investigated in some of the patients. Of the 70 patients studied, 49 (70%) were diagnosed with pyelonephritis and 21 (30%) had bacteremia. Mean (±SD) hemoglobin (Hgb) on hospital admission was 10.9±1.27 g/L as compared with 12.1±1.03 g/L of the controls, P<0.0001. Compared with normal-for-age Hgb values as a standard, 42 (60%) cases were identified as anemic. Compared with hospitalization values, Hgb and hematocrit (Hct) were significantly higher in prehospitalization or posthospitalization, whereas WBC values were significantly lower. All parameters of hemolysis, namely reticulocytes, bilirubin, lactate dehydrogenase (LDH), and haptoglobin, were normal. Bacteremia and pyelonephritis are accompanied by a significant drop in Hgb level. There is no evidence of hemolytic anemia in these patients.
