Insights
Lactobacillus reuteri DSM 17938 (L. reuteri) effectively shortens diarrhea duration and improves cure rates in children. It may also reduce community-acquired diarrhea in healthy children, but evidence for preventing hospital-acquired or antibiotic-associated diarrhea is limited.
Area of Science:
- Microbiology
- Pediatrics
- Gastroenterology
Background:
- Probiotic efficacy varies significantly.
- Understanding specific probiotic benefits is crucial for targeted therapeutic use.
Purpose of the Study:
- To evaluate the effectiveness of Lactobacillus reuteri DSM 17938 (L. reuteri) in managing various childhood diarrheal diseases.
- To synthesize evidence from randomized controlled trials (RCTs) on L. reuteri's therapeutic and preventive roles.
Main Methods:
- Comprehensive literature search of Medline, Embase, Cochrane Library, and trial registries up to January 2016.
- Inclusion of randomized controlled trials (RCTs) with no language restrictions.
- Systematic review and meta-analysis of L. reuteri's impact on diarrhea duration, cure rates, and incidence.
Main Results:
- L. reuteri administration significantly reduced diarrhea duration (MD -24.82 h) and increased cure rates in treatment trials (3 RCTs, n=256).
- No significant reduction in nosocomial, rotavirus, or general diarrhea risk was observed in hospitalized children (2 RCTs, n=290).
- Limited evidence suggests L. reuteri may reduce community-acquired diarrhea in healthy children, but effects on antibiotic-associated diarrhea were inconclusive (1 RCT, n=97).
Conclusions:
- L. reuteri demonstrates therapeutic benefits by reducing diarrhea duration and enhancing cure rates in children.
- L. reuteri shows potential in preventing community-acquired diarrhea in healthy pediatric populations.
- Further research is needed to clarify L. reuteri's role in preventing hospital-acquired and antibiotic-associated diarrhea due to limited or inconclusive evidence.
Background:
Not all probiotics are equal.
Aim:
To investigate the efficacy of Lactobacillus reuteri DSM 17938 (L. reuteri) in the management of various types of diarrhoeal diseases in children.
Methods:
Medline, Embase, the Cochrane Library, trial registries and reference lists of included studies were searched in January 2016, with no language restriction, for randomised controlled trials (RCTs).
Results:
Eight RCTs (n = 1229) met the inclusion criteria. In treatment trials, L. reuteri administration reduced the duration of diarrhoea (three RCTs, n = 256, mean difference, MD -24.82 h, 95% CI -38.8 to -10.8) and increased the cure rate on day 1 and day 2. However, heterogeneity and wide confidence intervals call for caution in interpreting results. In preventive trials carried out in hospitalised children, based on the findings from two RCTs (n = 290), there was no significant reduction in the risk of nosocomial diarrhoea, rotavirus diarrhoea or diarrhoea of any origin with L. reuteri administration. Based on one RCT (n = 97), there was no effect of L. reuteri on the risk of antibiotic-associated diarrhoea. However, the evidence is limited because the overall frequency of diarrhoea was surprisingly low. In preventive studies carried out in apparently healthy children, L. reuteri reduced diarrhoeal outcomes in one RCT; the evidence from another trial was less convincing.
Conclusions:
In therapeutic settings, L. reuteri administration reduces the duration of diarrhoea and increases the chance of cure. In preventive settings, L. reuteri has the potential to reduce the risk of community-acquired diarrhoea in otherwise healthy children.
