Insights
Two probiotic Lactobacillus strains, L. rhamnosus 19070-2 and L. reuteri DSM 12246, reduced diarrhea duration and rotavirus excretion in children. Early intervention showed the most significant benefits, shortening hospital stays.
Area of Science:
- Microbiology
- Pediatrics
- Gastroenterology
Background:
- Acute childhood diarrhea remains a significant health concern, with limited effective therapeutic options.
- Probiotic interventions, particularly using Lactobacillus strains, show promise in managing diarrheal diseases.
- Identifying specific strains with proven efficacy is crucial for advancing oral bacteriotherapy.
Purpose of the Study:
- To evaluate the therapeutic potential of two novel probiotic Lactobacillus strains, L. rhamnosus 19070-2 and L. reuteri DSM 12246, in treating acute childhood diarrhea.
- To assess the impact of these probiotics on diarrhea duration, stool consistency, rotavirus excretion, and hospitalization length.
Main Methods:
- A randomized controlled trial involving 69 hospitalized children with acute diarrhea.
- Participants received a mixture of L. rhamnosus 19070-2 and L. reuteri DSM 12246 (10(10) CFU each) or placebo twice daily for 5 days.
- In vitro and healthy volunteer studies preceded strain selection to confirm probiotic characteristics.
Main Results:
- Probiotic treatment reduced the diarrheal phase by 20% (82h vs. 101h, P=0.07), with significantly fewer patients having loose stools at study end (P=0.03).
- Early intervention (diarrhea <60h) demonstrated a clear probiotic effect, reducing diarrhea duration (80h vs. 130h, P=0.003) and hospitalization by 48% (P=0.03).
- Rotavirus antigen detection was significantly lower in the probiotic group (12% vs. 46%, P=0.02).
Conclusions:
- L. rhamnosus 19070-2 and L. reuteri DSM 12246 effectively ameliorated acute diarrhea in hospitalized children.
- Oral bacteriotherapy with these strains reduced rotavirus shedding and length of hospital stay.
- The most pronounced benefits were observed in children receiving early intervention during the diarrheal phase.
Background:
Oral bacteriotherapy promotes recovery from acute childhood diarrhea, but few strains have been shown to have therapeutic potentials. We examined the effect of two newly identified probiotic Lactobacillus strains in acute childhood diarrhea.
Methods:
Sixty-nine children were randomized during hospitalization for acute diarrhea to receive a mixture of Lactobacillus rhamnosus 19070-2 and Lactobacillus reuteri DSM 12246, 10(10) colony-forming units of each strain or placebo twice daily for 5 days. Before selection of these stains their potential probiotic characteristics were demonstrated in vitro and in healthy volunteers.
Results:
In patients receiving probiotics, the diarrheal phase was reduced by 20%. The duration of diarrhea was 82 h in the treatment group vs. 101 h in the control group (not significant, P = 0.07). However, 3 of 30 patients from the treatment group vs. 13 of 39 from the control group still had loose stools at the end of the study period (P = 0.03). In patients with diarrhea for <60 h before start of treatment (early intervention), a clear effect of the probiotics was demonstrated (80 h in the treatment group vs. 130 h in the control group, P = 0.003). After early intervention, the length of hospitalization was reduced by 48% (3.5 vs. 1.7 days, P = 0.03). At the end of the intervention, rotavirus antigen was found in 12% of patients from the treatment group vs. 46% from the control group (P = 0.02).
Conclusions:
The two probiotics, L. rhamnosus 19070-2 and L. reuteri DSM 12246, ameliorated acute diarrhea in hospitalized children and reduced the period of rotavirus excretion. Oral bacteriotherapy was associated with a reduced length of hospital stay. The beneficial effects were most prominent in children treated early in the diarrheal phase.
