To investigate the clinical features of invasive fungal infections (IFI) in the pediatric intensive care unit (PICU) and, to provide a basis for the effective prevention and treatment of IFI.
Retrospective analysis was performed on the clinical features and treatment outcomes of 38 children with IFI who were admitted to the PICU of Wuhan Children's Hospital between January 2009 and August 2012.
Pulmonary fungal infection (89%) was the most common among the 38 cases. Before diagnosis of IFI, all patients had severe underlying diseases and received several broad-spectrum antibiotics, including carbapenems, which were used in 95% of cases; 47% of all cases had been treated with corticosteroids systemically; all patients had received invasive operations, and 47% of them had undergone endotracheal intubation and mechanical ventilation. None of these cases had either typical clinical symptoms and signs or specific imaging findings. Fifty-six strains of fungi were isolated, with Candida albicans (41%), Aspergilli (25%), and Mucor (20%) being the most common ones. All patients received timely antifungal therapies, 15 cases were cured and 16 cases showed improvements, with a response rate of 82%, and the rate of adverse events was 16%.
In the PICU, the respiratory tract is the most common site of IFI infection, and Candida albicans is the leading pathogen. Severe underlying diseases, use of broad-spectrum antibiotics and corticosteroids, and invasive operations are the main risk factors for IFI in the PICU. Early diagnosis and timely treatment with high-performance antifungal drugs can improve the prognosis in children with IFI.
探讨儿科重症监护病房(PICU)侵袭性真菌感染(IFI)的临床特征,为IFI的有效防治提供依据。
回顾性分析2009年1月至2012年8月间武汉儿童医院PICU收治的38例IFI患儿的临床特征及治疗转归。
38例患儿中肺部真菌感染最为常见(89%)。IFI确诊前,所有患儿均患有严重基础疾病,均接受过多种广谱抗生素治疗,其中碳青霉烯类抗生素使用率达95%;47%的患儿接受过全身糖皮质激素治疗;所有患儿均接受过侵入性操作,47%的患儿接受过气管插管及机械通气。所有病例均无典型临床症状体征及特异性影像学表现。共分离出56株真菌,其中白色念珠菌最常见(41%),其次为曲霉菌(25%)和毛霉菌(20%)。所有患儿均接受了及时的抗真菌治疗,15例治愈,16例好转,有效率82%,不良事件发生率16%。
在PICU中,呼吸道是IFI最常见的感染部位,白色念珠菌是主要病原菌。严重基础疾病、广谱抗生素及糖皮质激素的使用、侵入性操作是PICU患儿发生IFI的主要危险因素。早期诊断并及时应用高效抗真菌药物治疗可改善IFI患儿预后。
