This is a cohort study of pediatric outpatients receiving total parenteral nutrition (TPN) and follow-up care in a Tennessee hospital between January and June 1999. The study was conducted following an increase in the incidence of candidemia. Of 13 children receiving home TPN, five had candidemia; three were due to Candida parapsilosis. Case patients were more likely to have an underlying hematologic disease (P = 0.02) as well as previous history of fungemia (P = 0.02). Two case patients had successive candidemia episodes 3 months apart; karyotypes and RAPD profiles of each patient's successive C. parapsilosis isolates were similar. Candida spp. were frequently detected in hand cultures from cohort members (four of 10) and family member caregivers (nine of 11); C parapsilosis was isolated from five caregivers. Our findings underscore the challenges of maintaining stringent infection control practices in the home health care setting and suggest the need for more intensive follow-up and coordination of home TPN therapy among pediatric patients.
这是一项对1999年1月至6月间在田纳西州一家医院接受全胃肠外营养(TPN)及后续护理的儿科门诊患者进行的队列研究。该研究是在念珠菌血症发病率上升后开展的。在13名接受家庭TPN治疗的儿童中,有5名发生了念珠菌血症;其中3例由近平滑念珠菌引起。病例患者更有可能患有潜在血液系统疾病(P = 0.02)以及既往真菌血症病史(P = 0.02)。两名病例患者相隔3个月先后发生念珠菌血症发作;每位患者先后分离出的近平滑念珠菌菌株的核型和随机扩增多态性DNA(RAPD)图谱相似。念珠菌属在队列成员(10人中有4人)和家庭成员护理人员(11人中有9人)的手部培养物中频繁检出;从5名护理人员中分离出了近平滑念珠菌。我们的研究结果强调了在家庭医疗环境中维持严格感染控制措施的挑战,并表明需要对儿科患者的家庭TPN治疗进行更密切的随访和协调。
