Insights
This study found that a probiotic mixture significantly reduced diarrhea duration and hospital stays in children. Probiotics also helped restore gut flora and modulate immune responses for better recovery.
Area of Science:
- Microbiology
- Immunology
- Pediatrics
Background:
- Acute infectious diarrhea is a significant cause of illness and financial strain in children.
- The study aimed to assess the impact of probiotics on diarrhea in pediatric patients.
Purpose of the Study:
- To evaluate the clinical, microbiologic, and immunologic effects of a specific probiotic mixture (Bio-three) in children with acute infectious diarrhea.
Main Methods:
- A randomized controlled trial involving 304 children aged 3 months to 6 years with acute diarrhea.
- Participants received either Bio-three (a probiotic blend) or a placebo for 7 days.
- Fecal and blood samples were analyzed for bacterial counts and cytokine profiles.
Main Results:
- The probiotic group experienced a shorter mean diarrhea duration (60.1 vs. 86.3 hours) and hospital stay (P = 0.003, P = 0.009).
- Probiotic use increased beneficial bacteria (Bifidobacteria, Lactobacillus) and modulated immune responses, including increased IL-10 and down-regulated tumor necrosis factor-alpha.
Conclusions:
- The Bio-three probiotic mixture effectively reduced diarrhea severity and hospital stay in children.
- Probiotics contribute to restoring intestinal flora and enhancing host immunity by balancing pro- and anti-inflammatory cytokines.
Background:
Acute infectious diarrhea is a major cause of childhood morbidity and economic burden for families. We evaluate the clinical, microbiologic, and immunologic effects of probiotics in acute infectious diarrhea.
Methods:
Children (n = 304) aged 3 months to 6 years hospitalized for acute diarrhea were randomized to receive Bio-three (a mixture of Bacillus mesentericus, Enterococcus faecalis, and Clostridium butyricum) or placebo orally 3 times daily for 7 days. Fecal samples were homogenized for bacterial culture and blood cells were isolated for cell culture and cytokine analysis. This study is registered (NCT00463190).
Results:
The mean duration of diarrhea after start of therapy was 60.1 hours in the probiotics group versus 86.3 hours in the placebo group (P = 0.003). Hospital stay was shorter in the probiotics group than in the placebo group (P = 0.009). Counts of Bifidobacteria and Lactobacillus species were elevated in stool culture of the probiotics (Bio-three) group. IL-10 was increased in the serum and supernatants of cell culture in the probiotics group, and tumor necrosis factor-alpha values were down-regulated. Interferon- gamma and IL-12 were mildly elevated in the probiotics group, compared with the placebo group.
Conclusions:
This probiotics mixture reduced the severity of diarrhea and length of hospital stay in children with acute diarrhea. In addition to restoring beneficial intestinal flora, probiotics may enhance host protective immunity such as down-regulation of pro-inflammatory cytokines and up-regulation of anti-inflammatory cytokines.
