Rotavirus infection can cause significant problems including diarrhea in the newborn. This is particularly true in babies weighing less than 2500 g (low birthweight infants). Rotavirus infection is becoming more common in newborn babies and can spread from one baby to another in the neonatal unit. Administration of antibodies against rotavirus to babies may prevent this infection and its spread in the neonatal unit. In this review, only one small trial was identified. Currently, there is not enough evidence to recommend the use of antibodies against rotavirus to babies exposed to rotavirus infection. More research is needed.
閱讀完整摘要
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.
目的
To determine the effectiveness and safety of oral immunoglobulin preparations for the prevention of rotavirus infection in hospitalized low birthweight infants (birthweight < 2500 g)
搜尋策略
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
選擇標準
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.
資料收集與分析
The two review authors independently abstracted data from the included trials.
主要結果
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.
作者結論
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.
