Insights
Probiotic-supplemented milk formula may protect children from rotavirus infection. Supplementing with Bifidobacterium Bb12 reduced symptomatic rotavirus infections in young children.
Area of Science:
- Pediatric Nutrition
- Microbiology
- Immunology
Background:
- Diarrheal diseases are a significant health concern in infants and young children.
- Rotavirus is a common cause of gastroenteritis in this age group.
- Probiotics are live microorganisms that may confer health benefits.
Purpose of the Study:
- To investigate if probiotic-supplemented milk-based formula can protect children from rotavirus infection.
- To assess the impact of Bifidobacterium Bb12 and Streptococcus thermophilus on rotavirus-specific IgA antibody levels.
Main Methods:
- A randomized controlled study involving 175 children aged 6-36 months.
- Children received either standard milk-based formula, formula with Bifidobacterium Bb12, or formula with both Bifidobacterium Bb12 and Streptococcus thermophilus.
- Salivary rotavirus-specific IgA antibody levels were measured to indicate rotavirus infection.
Main Results:
- 30.4% of children in the control group showed a significant increase in rotavirus antibody titers, indicating subclinical infection.
- Children receiving Bifidobacterium Bb12-supplemented formula showed no significant change in antibody titers.
- The majority of children in the probiotic groups did not exhibit significant changes in antibody levels.
Conclusions:
- Supplementation with Bifidobacterium Bb12 in milk-based formula may protect children from symptomatic rotavirus infection.
- Probiotics show potential in preventing rotavirus-related illness in young children.
- Further research is warranted to confirm these findings and explore mechanisms.
Abstract:
This study was conducted at Pakkred Babies Home, Bangkok, Thailand; with the hypothesis that children receiving probiotic-supplemented milk-based formula may be protected from developing diarrheal diseases. Salivary rotavirus-specific IgA antibody was used as an indicator of rotavirus infection. One hundred and seventy-five children, aged 6-36 months, were enrolled in the study. They were divided into 3 groups according to the type of formula given. There were 81 episodes of diarrhea during an 8-month study period, most of which were caused by bacterial enteropathogens. Ninety-seven pairs of salivary samples were adequate for the analysis of rotavirus antibody. Among 23 children receiving milk-based follow-up formula and serving as control group, 30.4 per cent of them had > or = 4-fold increase in the antibody titre, indicating subclinical rotavirus infection. The majority of children in the other 2 study groups, receiving the same formula supplemented with either Bifidobacterium Bb12 alone or together with Streptococcus thermophilus, had no significant change in the antibody titres between the two time points. The results of this study support our hypothesis that children receiving bifidobacteria-supplemented milk-based formula may be protected against symptomatic rotavirus infection.
