Abstract

Purpose : A full view of the spectrum of all bacterial diseases in healthy children is essential to the establishment of public health priorities. Accurate information on the relative importance of the various pathogens in terms of the age of the affected patients, the site of infection and the case fatality rate are valuable to the clinician in choosing antimicrobial treatments. Methods : Fifty-nine episodes of bacteremia were analysed. Data were collected at Ilsan Paik Hospital from January 2000 to December 2003. Analysis of each collected episode included isolating pathogen from blood culture, diagnosis, hospital course, isolating pathogens from other tissue sites, and studying results of antimicrobial sensitivity tests. Results : Fifty-nine cases of community-acquired bacteremia were reviewed. The most common pathogen was Staphylococcus aureus(11 cases, 18.6 percent), followed by Salmonella(10 cases, 16.9 percent), E. coli(7 cases, 11.9 percent), Streptococcus pneumoniae(five cases, 8.5 percent), Streptococcus viridans(5 cases 8.5 percent). The most common diagnosis was bacteremia without an indentified focus(61 percent), followed by meningitis(12 percent), bacteremia with enteritis(10.2 percent) and bacteremia with urinary tract infection(8.5 percent). Salmonella was still an important causative agent of bacteremia. The relative importance of Haemophilus influenza and Streptococcus pneumoniae was lower than in other studies. The most common organism responsible for bacteremia without an identified focus was Staphylococcus aureus. The case-fatality was 3.4 percent for all cases of bacteremia. Conclusion : We reviewed the etiology of community-acquired bacteremia. These data may be useful in the establishment of public health priorities and serve as a reference for selection of antibiotics in the empirical therapy of suspected invasive bacterial infection.

목 적 : 지역사회 획득 균혈증의 원인균, 사망률, 진단과 임상 양상에 대해 연구하여 임상의들의 총체적인 세균질환에 대한 인식을 환기시키고 치료의 실제에 도움이 되고자 하였다. 방 법 : 2000년 12월부터 2003년 12월까지 3년 동안 인제대학교 일산백병원의 소아과 병동에 입원한 15세 미만의 환아 중 지역사회 획득 균혈증 59례에 대한 연구를 시행하였다. 결 과 : 지역사회 획득 균혈증의 가장 흔한 원인균은 황색포도알균(11례, 18.6%)이었고, 그 다음이 살모넬라균(10례, 16.9%), 대장균(7례, 11.9%), 폐렴사슬알균(5례, 8.5%), Streptococcus viridans(5례, 8.5%)였다. 황색포도알균은 국소 부위가 없는 균혈증과 관절염 혹은 골수염을 야기하며 12개월 미만에서 가장 흔한 균혈증의 원인이었고 살모넬라균은 국소부위가 없는 균혈증과 균혈증을 동반한 위장관염을 야기하며 1에서 4세 사이의 가장 흔한 균혈증의 원인균 이었다. 대장균은 1세 미만에서 요로감염을 동반한 균혈증과 국소부위가 없는 균혈증을, 폐렴사슬알균은 국소부위가 없는 균혈증과 수막염을, Streptococcus viridans는 국소부위 없는 균혈증의 원인이 되었다. 임상 진단명으로는 국소부위가 없는 균혈증이 36례(61%)로 가장 많았고 다음은 수막염이 7례(12%), 균혈증을 동반한 위장관염이 6례(10%), 요로감염이 5례(8.5%)였다. 대상 환아 59명 중 2례 3.4%가 사망하였고 각각 수막염균과 폐렴사슬알균에 의한 수막염으로 진단되었다. 결 론 : 지역사회 획득 균혈증의 원인으로 황색포도알균과 살모넬라균이 가장 흔하였고 폐렴사슬알균의 발생 빈도는 과거에 비해 감소된 경향을 보였다.
