摘要 中文概呼吸道合胞病毒(RSV)是2岁以下儿童呼吸道感染最常见的病原体,也是引起婴儿病毒感染所致死亡的主要原因。到目前为止,尚未见加拿大萨斯喀彻温省RSV流行病学的研究报道。本研究的目的是描述2002年7月至2005年6月期间在萨斯喀彻温省的两个儿科三级医疗中心,即皇家大学医院(RUH)和萨斯卡通和里贾纳总医院(RGH),因RSV感染住院的儿童的流行病学特点及疾病严重程度,其中部分患儿有帕利珠单抗(palivizumab)预防史。 在上述2个医疗中心住院时间≥24h的儿童(年龄:从出生到16岁11个月)经实验室病毒鉴定确诊为RSV感染的儿童纳入本研究。在RUH中心,患儿鼻咽部分泌物经直接荧光抗体(DFA)检测阳性者确诊为RSV感染。如果DFA为阴性,则对该标本进行病毒培养。在RGH中心,所有患儿鼻咽部分泌物标本均进行DFA检测和病毒培养。确诊后对患儿的健康记录进行回顾性分析,内容包括患儿的人口统计信息、转诊模式、帕利珠单抗预防史、感染严重程度及转归。目前尚无统一的感染严重程度的判断标准,本研究根据住院时间、是否需要小儿重症监护及持续时间、是否机械通气等进行评估。在研究期间,萨斯喀彻温省的帕利珠单抗预防的标准与加拿大儿科学会(CPS)的建议一致。 2002年7月至2005年6月3年期间,总共有590名RSV儿童(包括324名男童)住院治疗,共602次住院记录,其中12名儿童住院1次以上。入院时患儿中位实足年龄为5.3个月,平均住院时间为4.0d(范围:〈1d至121.2个月)。82.4%的患儿出生时胎龄≥36周,7.5%为33-35周,9.5%≤32周。RSV感染住院情况呈现季节性模式,其中大部分发生在三月和六月。患儿最常见的临床表现为细支气管炎(70.2%),38.1%表现为肺炎,17.3%为上呼吸道感染,0.5%表现为哮吼(患儿可能同时� Objective To describe the epidemiology and severity of illness of children hospitalized with respiratory syncytial virus (RSV) infection, including those who received palivizumab prophylaxis, at Royal University Hospital (RUH), Saskatoon and Regina General Hospital (RGH) from July 2002 to June 2005. Methods Children hospitalized for ≥ 24 hours with laboratory-confirmed RSV infection were enrolled, and their health records were retrospectively reviewed for patient demographics and referral patterns, use of palivizumab prophylaxis, severity of infection (length of hospitalization, need for and duration of pediatric intensive care and mechanical ventilation) and outcome of infection. Results A total of 590 children (324 males) were hospitalized over the three years. The median chronological age at admission was 5.3 months, and median hospital stay was 4.0 days. Gestational age at birth was≥36 weeks in 82.4%of patients. RSV disease severity was mild to moderate in 478 patients (81.0%) and severe in 110 (18.6%). Thirty-nine patients (6.6%) required pediatric intensive care unit admission, for a median of 5.0 days. Twenty-two of these patients (56%) were mechanically ventilated for a median of 6.0 days. Two children died, not attributed to RSV infection. Twenty-two patients had received palivizumab prophylaxis before hospital admission, with 18 completing at least 2 of the monthly doses. Most of these children (17/22) had mild to moderate illness. Conclusions RSV causes signiifcant morbidity in Saskatchewan, affecting predominantly term infants. The majority of illness is mild to moderate. Some patients who have received palivizumab may still develop signiifcant RSV disease.
