Abstract

Purpose : Bacteremia is one of the most common causes of morbidity and mortality in children with cancer. The aim of this study was to evaluate the clinical features of bacteremia in pediatric cancer patients. Methods : We retrospectively analyzed bacteremia episodes occurred in pediatric cancer patients at Samsung Medical Center from January 2008 to December 2010. We excluded bacteremia episodes after hematopoietic stem cell transplantation. Results : A total of 141 blood cultures were positive in 121 patients. Thirteen cultures due to contamination were excluded. For analysis, 128 bacteremia episodes in 108 children were included. Gram-positive organisms accounted for 46.9% (60/ 128) and gram-negative organisms for 53.1% (68/128). The source of bacteremia was identified in 21.1% of episodes. Bacteremia due to catheter related infection was observed in 9.4% of episodes (12/128 episodes) and gram-positive organisms were isolated in 75% of episodes (9/12). There were 10 cases (7.8%) of bacteremia associated with septic shock and gramnegative organisms were isolated in 80% of episodes (8/10). Relapses were documented within 30 days in 2 patients who cleared bacteremia which was confirmed after negative blood cultures. Mortality associated with bacteremia was not observed. Conclusion : Continuous monitoring is needed to maintain the tailored strategies to manage pediatric cancer patients with neutropenic fever who are at high risk of developing bacteremia in each institution.

목 적 : 본 연구는 균혈증이 발생한 소아암 환자의 임상 양상을 분석하고자 실시하였다. 방 법: 2008년 1월부터 2010년 10월까지 삼성서울병원에 입원한 소아암 환자에서 발생한 균혈증 예를 후향적으로 분석하였다. 조혈모세포 이식 환자는 제외하였다. 결 과:총 141예의 양성 혈액 배양 검사 중 오염균을 제외한 108명의 환자 128예의 혈액 배양 양성 결과를 분석하였다. 그람 양성균은 60예, 그람 음성균은 68예에서 동정되었고 균혈증의 원인은 21.1%에서 확인되었다. 중심정맥관 연관 균혈증은 9.4% (12/128예)에서 발생하 였고, 그람 양성균의 빈도가 75% (9/12회)로 관찰되었다. 쇼크가 10예(7.8%)에서 발생하였으며 그람 음성균의 빈도가 80% (8/10회)였다. 균이 음전된 후 30일 내에 균혈증이 재발한 환자가 2명 있었고 균혈증 관련 사망예는 없었다. 결 론 : 소아암 환자의 균혈증 치료에 있어서 알맞은 치료 지침을 위하여 지속적인 모니터링이 필요하다.
