Summary

The trial will be divided into three groups, the experimental group: (I) probiotic A formula, (II) probiotic B formula; control group: (III) regular formula (Youluck infant formula). Inclusion criteria included: (1) the normal spontaneous delivery (NSD) full-term health infants (≧37 weeks) and birth weight more than 2500 grams and (2) subjects who are expected to breastfeed are eligible for the trial after informed consent form is signed by the parents. Exclusion criteria included: infants with chronic diarrhea, hemangioma, cerebral hemorrhage, severe asphyxia (stage III), fetal chromosomal abnormalities, cyanotic congenital heart disease, intestinal hypoplasia or abnormal immune function after birth, liver failure, breastfeeding within two months after birth, taking other probiotic products within two weeks after birth, treatment with antibiotics during acute infection and diagnosis of allergies, gastroenteritis, respiratory infections will be excluded. The study will be conducted for half a year, 5 cans of Youluck infant formula are provided for each subject during the test period. The Youluck infant formula is sponsored free of charge by glac biotech Co., Ltd. During hospitalization, the infant will be feed by same group of experienced nurses and all infants will be monitored for adverse conditions such as vomiting, diarrhea or bloating every day.

Description

Probiotics were defined as an ''live microorganisms, which, when administered in adequate amounts, conferred a health benefit on the host. Before 2005, some animal experiments indicated that probiotics could help weight gain. In 2006, there was a team observed the growth of infants who received infant formula with probiotics. The study found that infants who received infant formula with probiotics for half a year had higher height and weight than infants who received regular formula, and the defecation frequency was increased. So far, clinical studies had proved that probiotics had an efficacy on gastrointestinal immune regulation. Some studies had found that concentrated preparations mixed with various probiotics had therapeutic effects on inflammatory bowel diseases. The latest double-blind study of infants with acute diarrhoea showed that oral dehydration supplements enriched probiotics and zinc could reduce the severity of diarrhoea on day 2 without any side effects. Therefore, more and more probiotic clinical studies had suggested that probiotics could be used to regulate gastrointestinal related diseases.

According to statistics, the proportion of atopic dermatitis in infants and children worldwide is about 10-20%, and about 30% of toddlers with more than three episodes of wheezing bronchitis may develop persistent asthma. Therefore, how to effectively prevent the occurrence of allergic diseases was still an urgent goal for infants and young children. There is now evidence in mice and humans of an early-life "critical window" in which the effects of gut microbial dysbiosis are most influential in human immune development. Investigators showed that infants at risk of asthma exhibited transient gut microbial dysbiosis during the first 100 days of life. Inoculation of the relatively lower abundance of the genus to asthmatic mice ameliorated airway inflammation. These results enhanced the potential for future microbe-based diagnostics and therapies, potentially in the form of probiotics, to prevent the development of asthma and other related allergic diseases in children.

In addition, respiratory infections were diseases that needed attention during the growth phase of infants and young children. The most common treatment for respiratory infections or acute otitis media in infants and young children was using antibiotics, but antibiotic treatment might lead to antibiotic resistance and intestinal microbial disorders, which might promote colonization of pathogens. In recent years, probiotics had attracted more and more attention for the prevention of respiratory infections. For example, investigators showed that using Bifidobacterium probiotics in children before 2 years old might reduce the incidence of respiratory infections.

Based on the above studies, Investigators will use infant formula with probiotics to infants. The study will assess the growth, incidence of allergies, gastroenteritis and respiratory infections of infants. This observational study will be conducted at the China Medical University Children's Hospital performed a double-blind randomized trial.

The trial will be divided into three groups, the experimental group: (I) probiotic A formula, (II) probiotic B formula; control group: (III) regular formula (Youluck infant formula). Inclusion criteria included: (1) the normal spontaneous delivery (NSD) full-term health infants (≧37 weeks) and birth weight more than 2500 grams and (2) subjects who are expected to breastfeed are eligible for the trial after informed consent form is signed by the parents. Exclusion criteria included: infants with chronic diarrhea, hemangioma, cerebral hemorrhage, severe asphyxia (stage III), fetal chromosomal abnormalities, cyanotic congenital heart disease, intestinal hypoplasia or abnormal immune function after birth, liver failure, breastfeeding within two months after birth, taking other probiotic products within two weeks after birth, treatment with antibiotics during acute infection and diagnosis of allergies, gastroenteritis, respiratory infections will be excluded. The study will be conducted for half a year, 5 cans of Youluck infant formula are provided for each subject during the test period. The Youluck infant formula is sponsored free of charge by glac biotech Co., Ltd. During hospitalization, the infant will be feed by same group of experienced nurses and all infants will be monitored for adverse conditions such as vomiting, diarrhea or bloating every day. After the study is completed, the remaining probiotic milk powder will be subjected to high temperature and high pressure for sterilization, and then placed in an infectious garbage bag or infective trash can, and destructed by a cleaning company.

Sample size calculation is based on the literature. The incidence of enteritis, allergic disease or respiratory infection in infants is about 30%. Investigators assume that the experimental group has a 50% improvement compared with the control group. If investigators allow 5% chance of type 1 error (α=0.05) and 10% chance of type 2 error (β=0.1), then the required sample size in each group will be 60 people (total 180 infants in three groups).

The research data will be based on International Business Machines Statistical Product and Service Solutions (IBM SPSS) for analytical statistics. Normally distributed data were analyzed using Student's t-test two-tailed assay, and non-normally distributed data were analyzed using the Wilcoxon signed-rank test. Data were presented as mean ± standard deviation (SEM) or median, with P values < 0.05 being considered statistically significant.
