Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This project aims to study the benefits of probiotics namely Bifidobacterium lactis subsp. infantis B8762 in treatment of respiratory and gastrointestinal illnesses in children, which are found common among pre-school children in Malaysia aged below 7-years old.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Respiratory and gastrointestinal illnesses are the most common acute diseases in children where no virtually effective treatments or prophylaxes are available for these infections. Probiotics on the other hand have gained increasing evidences as an effective therapy in preventing respiratory and gastrointestinal illnesses. While the precise mechanisms of using probiotics are largely unknown, speculations include: probiotics compete against pathogens; increase the barrier function in respiratory epithelium; immuno-stimulatory effects by enhancing cellular immunity with increased activity of natural killer cells and macrophages in airways and gut. Hence, probiotics may offer safe means of reducing the risk of respiratory and gastrointestinal illnesses, antibiotic use, and the risk of recurrent infections, thereby represent a simple, safe, effective, available and affordable method for preventing respiratory and gastrointestinal infections in children.

Among the various types of probiotics, Bifidobacterium is one of the best-known probiotic genus in the world, and it is widely applied in the dairy industry as a probiotic. Evidences from more than 100 scientific publications based on in vitro, in vivo, and clinical studies and long consumption history support the safety and health benefits of Bifidobacterium strains. The ingestion of yogurt fortified with B. longum reduced harmful bacteria such as Enterobacteriaceae, Streptococcus and C. perfringens, while at the same time alter the microbiota gut profile of volunteers with a significant increase of beneficial microbes Bifidobacterium and Lactobacillus species. Additionally, putrefactive substances in the intestinal environment were also reduced in the presence of the probiotic supplement. Such findings suggest that Bifidobacterium strains are safe and could be used further to evaluate its effect in preventing diarrhea and/or respiratory-related illness prevalence in young children.

Probiotic (Bifidobacterium lactis subsp. infantis B8762) adheres to probiotic properties such as excellent tolerance to gastric acid, intestinal fluid and bile salt of the digestive system. Both probiotic and placebo products are manufactured under an ISO9001, ISO22000 and HACCP conditions. All products do not contain any animal-origin ingredients. The probiotic product contains probiotic and carrier while placebo contains only carrier. Sachets of products containing probiotic and placebo appear as light yellow powder. Both probiotic and placebo products are kept at storage temperature range below 30oC according to the condition recommended by the manufacturer.

A total number of 120 pre-school children with respiratory diseases aged below 7-years old will be recruited for this study.
