Rotavirus is a common neonatal nosocomial viral infection and epidemics with the newer P(6)G9 strains have been reported. Local mucosal immunity in the intestine to rotavirus is important in the resolution of infection and protection against subsequent infections. Oral administration of anti-rotaviral immunoglobulin preparations might be a useful strategy in preventing rotaviral infections, especially in low birth weight babies.
To determine the effectiveness and safety of oral immunoglobulin preparations for the prevention of rotavirus infection in hospitalized low birthweight infants (birthweight < 2500 g)
The Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library), MEDLINE, EMBASE, CINAHL, biological Abstracts (BIOSIS), Science Citation Index for articles citing Barnes 1982 and the proceedings of the Pediatric Academic Societies from 1991 onwards were searched in July 2011. Ongoing trials were also searched at clinicaltrials.gov and controlled-trials.com
The criteria used to select studies for inclusion were: 1) design: randomized or quasi-randomized controlled trials; 2) participants: hospitalized low birthweight infants; 3) intervention: oral immunoglobulin preparations for prevention of rotavirus infection compared to placebo OR no intervention; 4) at least one of the following outcomes were reported: all cause mortality during hospital stay, mortality due to rotavirus infection during hospital stay, rotavirus infection , duration of diarrhea, need for rehydration, duration of viral excretion, duration of infection control measures, length of hospital stay in days, recurrent diarrhea or chronic diarrhea.
The two review authors independently abstracted data from the included trials.
One published study (Barnes 1982) was eligible for inclusion in this review. Barnes 1982 found no significant difference in the rates of rotavirus infection after oral gammaglobulin versus placebo in hospitalized low birthweight babies [RR 1.27 (95% CI 0.65 to 2.37)]. In the subset of infants who became infected with rotavirus after receiving gammaglobulin or placebo for prevention of rotavirus infection, there was no significant difference in the duration of rotavirus excretion between the group who had gammaglobulin (mean 2 days, range 1 to 4 days) and the group who had placebo (mean 3 days, range 1 to 6 days). Barnes 1982 reported no adverse effects after administration of oral immunoglobulin preparations.
AUTHORS' CONCLUSIONS: Current evidence does not support the use of oral immunoglobulin preparations to prevent rotavirus infection in low birthweight infants. Researchers are encouraged to conduct well-designed neonatal trials using the newer preparations of anti-rotaviral immunoglobulins (colostrum, egg yolk immunoglobulins) and include cost effectiveness evaluations.
轮状病毒是一种常见的新生儿医院内病毒性感染,且已有关于新型P(6)G9毒株引发疫情的报道。肠道对轮状病毒的局部黏膜免疫对于感染的消退以及预防后续感染至关重要。口服抗轮状病毒免疫球蛋白制剂可能是预防轮状病毒感染的一种有效策略,尤其是对于低体重儿。
确定口服免疫球蛋白制剂预防住院低体重婴儿(出生体重<2500克)感染轮状病毒的有效性和安全性。
2011年7月检索了Cochrane对照试验中心注册库(CENTRAL,Cochrane图书馆)、MEDLINE、EMBASE、CINAHL、生物学文摘数据库(BIOSIS)、引用Barnes 1982年文献的科学引文索引以及1991年起的儿科学术协会会议记录。还在clinicaltrials.gov和controlled-trials.com上检索了正在进行的试验。
用于选择纳入研究的标准为:1)设计:随机或半随机对照试验;2)参与者:住院低体重婴儿;3)干预措施:与安慰剂或无干预措施相比,口服免疫球蛋白制剂预防轮状病毒感染;4)至少报告以下一项结果:住院期间全因死亡率、住院期间轮状病毒感染导致的死亡率、轮状病毒感染、腹泻持续时间、补液需求、病毒排泄持续时间、感染控制措施持续时间、住院天数、复发性腹泻或慢性腹泻。
两位综述作者独立从纳入的试验中提取数据。
一项已发表的研究(Barnes 1982)符合本综述的纳入标准。Barnes 1982发现,住院低体重婴儿口服丙种球蛋白与安慰剂后,轮状病毒感染率无显著差异[相对危险度1.27(95%置信区间0.65至2.37)]。在接受丙种球蛋白或安慰剂预防轮状病毒感染后感染轮状病毒的婴儿亚组中,接受丙种球蛋白的组(平均2天,范围1至4天)与接受安慰剂的组(平均3天,范围1至6天)在轮状病毒排泄持续时间上无显著差异。Barnes 1982报告口服免疫球蛋白制剂后无不良反应。
目前的证据不支持使用口服免疫球蛋白制剂预防低体重婴儿感染轮状病毒。鼓励研究人员使用新型抗轮状病毒免疫球蛋白制剂(初乳、蛋黄免疫球蛋白)进行设计良好的新生儿试验,并纳入成本效益评估。
