초록

목적: CRAB(carbapenem-resistant Acinetobacter baumannii)의 침습적 감염은 중환자와 신생아에서 높은 이환율 및사망률과 관련이 있다. 이번 연구는 신생아 중환자실(NICU)에 입원한 신생아를 대상으로 CRAB 집단 발생 기간동안 세균 집락된 환자에서의 침습적 감염 발생에 대한 위험 요소와 CRAB이 집락된 환자와 침습적 감염된 환자간의 임상적 예후의 차이에 대하여 밝히고자 하였다. 방법: 2011년 5월부터 2012년 4월까지의 CRAB 집단 발생 기간 동안 서울대학교병원 NICU에서 CRAB이 집락되거나 침습적으로 감염되었던 45명의 신생아를 대상으로 후향적으로 정보를 수집하였다. 결과: CRAB의 침습적 감염은 7례(15.5%)에서 있었다. 동맥관 개존(57.9% vs. 100%, P=0.04)과 첫 세균 동정 당시의 기관 삽관 여부(44.7% vs. 100%, P=0.01)는 침습적 감염군에서 유의하게 높았다. 단변량 회귀분석을 시행한 결과, 3점 이하의 1분 아프가 점수와 14점보다 높은 CRIB II 점수의 침습적 감염에 대한 승산비는 각 9.9 (P=0.04)와 24.0(P=0.02) 이었다. 기관내관 총 유지 기간, 중심정맥관 총 유지 기간, CRAB 배양 지속 기간이 집락군보다 침습적 감염군에서 유의하게 길었다. 임상적 결과로 CRAB 이외의 세균혈증(26.3% vs. 71.4%, P=0.03)의 빈도가 침습적 감염군에서 더 높았으나 사망률(colonization group; 15.8% vs. infection group; 42.9%, P=0.13)은 두 군간의 차이가 없었다. 결론: 3점 이하의 아프가 점수와 14점보다 높은 CRIB II 점수, 임상적으로 의미있는 동맥관 개존증의 존재와 CRAB 발견 당시의 기관내관 삽관 여부에 따라 CRAB 집락 환자에서 침습적 감염에 대한 위험이 높아지는 것을 알 수 있었다. 이러한 환자에서는 CRAB 집단 발생 기간에 침습적 감염이 의심되는 경우 조기에 적절한 항생제 치료를 하는 것을 고려할 수 있겠다.

Abstract

Purpose: Invasive carbapenem-resistant Acinetobacter baumannii (CRAB) infection is associated with high morbidity and mortality rates in critically ill patients and neonates. We aimed to determine the risk factors of invasive infection in neonates with CRAB colonization, and differences in clinical outcomes between CRAB colonization and infection groups during the CRAB outbreak. Methods: We retrospectively collected data from 45 patients with CRAB during the outbreak at the Neonatal Intensive Care Unit of Seoul National University Children’s Hospital from May 2011 until April 2012. Results: CRAB infection developed in 7 neonates (15.5%). Clinically significant patent ductus arteriosus (colonization group, 57.9% vs. infection group, 100%; P=0.04) and intubation state at initial CRAB isolation (44.7% vs. 100%, respectively; P=0.01) were more prevalent in the infection group. Univariate analysis results showed that a 1-min Apgar score of ≤3 and a CRIB II score of >14 had odds ratios of 9.9 (P=0.04) and 24.0 (P=0.02), respectively, for invasive CRAB infection. Total lengths of intubation, central venous catheterization, and CRAB isolation were significantly longer in the invasive infection group than colonization group. As a clinical outcome, incidence of bacteremia other than CRAB (26.3% vs. 71.4%, P=0.03) was higher in the infection group, but there was no differences in the mortality rates between groups (15.8% vs. 42.9%, respectively; P=0.13). Conclusion: A 1-min Apgar score of ≤3, a CRIB II score of >14, clinically significant patent ductus arteriosus, and intubation state at initial isolation were found to be risk factors for invasive CRAB infection during the outbreak. During CRAB outbreak, early and appropriate antimicrobial treatment should be administered to high-risk patients.
