Insights
Limited research on probiotics for neonates with gastrointestinal surgical conditions shows mixed results on gut bacteria. More robust randomized controlled trials are needed to confirm their benefits in this vulnerable population.
Area of Science:
- Neonatal surgery
- Gastrointestinal disorders
- Microbiome research
Background:
- Neonates with major gastrointestinal surgical conditions are prone to feed intolerance, infections, and gut dysbiosis due to antibiotic use.
- Probiotic supplementation may help mitigate dysbiosis and improve clinical outcomes in these infants.
Purpose of the Study:
- To systematically review the existing evidence on the use of probiotics in neonates with major gastrointestinal surgical conditions.
Main Methods:
- A systematic search of major databases including Medline, Embase, and CENTRAL was conducted in September 2016.
- Included studies were randomized controlled trials (RCTs) focusing on probiotic supplementation in neonates with surgical gastrointestinal conditions.
Main Results:
- Two RCTs involving 32 neonates were analyzed.
- One study in gastroschisis neonates showed trends toward beneficial bacterial shifts with probiotics, while the other found significant differences in specific bacterial families between probiotic and no-probiotic groups.
Conclusions:
- Current evidence on probiotics for neonates with gastrointestinal surgical conditions is limited.
- Larger, adequately powered RCTs are necessary to establish the efficacy and safety of probiotics in this population.
Objectives:
Neonates with major gastrointestinal surgical conditions frequently suffer from prolonged feed intolerance, infections, and need multiple courses of antibiotics. All these put them at risk of gut dysbiosis. Probiotic supplementation has the potential to minimise dysbiosis and improve clinical outcomes in such infants. Hence, we aimed to conduct a systematic review of probiotics in neonates with major surgical conditions of the gut.
Methods:
Medline, Embase, the Cochrane Central Register of Controlled Trials (CENTRAL), and other databases were searched in September 2016.
Results:
Two randomised controlled trials (RCTs) were included; the first was conducted in 24 neonates with gastroschisis, the second in eight neonates with various surgical conditions. In the first study, the overall microbial communities were not significantly different between groups, though analysis of the final specimens demonstrated higher Bifidobacteriaceae, lower Clostridiaceae, and trends toward lower Enterobacteriaceae, Enterococcaceae, Staphylococcaceae, and Streptococcaceae in the probiotic group. In the second study, there were significantly more Streptcoccaceae in the faecal samples in the probiotic group and significantly more Bifidobacteriaceae in the no probiotic group (p < .05).
Conclusions:
There is limited evidence regarding the role of probiotics in neonates with gastrointestinal surgical conditions. Adequately powered RCTs are needed to address this issue.
