Abstract:
BACKGROUND: Despite the development of empiric antibiotics in treatment of neutropenic fever(NF) in pediatric cancer patients, bacterial infection is still the most important cause of death in these patients. In this study the authors analyzed clinical characteristics and tried to find out the possible risk factors of the pediatric cancer patients who succumbed to the documented bacterial infection after episodes of neutropenic fever. METHODS: 17 pediatric cancer patients expired after episodes of neutropenic fever(NF) in the pediatric department of Asan Medical Center from Mar. 1990 to Feb. 1996 were grouped by the results of bacterial culture. 7 cases (Group A) had documented bacterial culture results and 10 cases (Group B) had negative culture results. The clinical characteristics of these two groups were analyzed retrospectively. RESULTS: There were no differences in the types of cancer between the two groups. All the documented bacteria were gram negative organisms and all cultured from the blood. There were no differences between the two groups in the treatment duration, known risk factors of infection before and at the onset of fever, antibiotics administered, and interval from the onset of NF to the administration of antibiotics. The response rate of initial empiric antibiotics was lower in group A(14%) compared to Group B(40%), even though all the cultured organisms except 2 cases in Group A were sensitive to initial empirical antibiotics. Septic shock was the cause of death in 86% of Group A patients, but only in 10% of Group B patients. The other causes of death were progression of cancer, bleeding, hepatic failure, adult respiratory distress syndrome and multiple organ failure, which showed no difference between the 2 groups. The interval from the onset of fever to death was significantly shorter in Group A(6.2+/-2.3 days) compared to Group B(24.9+/-18.6 days). CONCLUSIONS: Bacterial infection is still the most frequent cause of death after NF. Most patients succumbed to the documented bacterial infection showed rapid progression of bacteremia to septic shock despite administration of sensitive antibiotics. The known risk factors of infection before the onset of NF and other treatment factors shows no differences between the two groups in this study. These results suggest that the bacteremia is obvious risk factor of poor outcome after NF episode, and antibiotics alone may be insufficient to prevent the rapid progression of septic shock in these patients.
