研究概览
简要总结
The newborn immune system is influenced by maternal immunity through both placenta and breastfeeding.
There exists a close interaction between the mother and the baby during gestation and lactation. Maternal milk contains a number of factors that protect the newborn against infections including 1) cytokines and their receptors which are also thought to play a role in the protection against allergies; 2) oligosaccharides with low molecular weight and 3) probiotic bacteria that contribute to the development of the newborn immune system.
Probiotics have a potent immunogenic activity as well as an immunoprotective potential in maternal milk after administration of probiotics during pregnancy and breastfeeding. In addition probiotics are supposed to play a role in the increased production of sphingomyelinase.
详细描述
Effects on cytokines, on sphingomyelinase and PAF hydrolysis capacity in the maternal milk of term newborns after maternal probiotics administration in the last four weeks of gestation and/or during the first month of lactation.
The newborn immune system is influenced by maternal immunity through both placenta and breastfeeding.
There exists a close interaction between the mother and the baby during gestation and lactation. Maternal milk contains a number of factors that protect the newborn against infections including 1)cytokines and their receptors which are also thought to play a role (albeit still partially controversial) in the protection against allergies; 2) oligosaccharides with low molecular weight and 3) probiotic bacteria that contribute to the development of the newborn immune system.
Probiotics have a potent immunogenic activity as well as an immunoprotective potential in maternal milk after administration of probiotics during pregnancy and breastfeeding. In addition probiotics are supposed to play a role in the increased production of sphingomyelinase, and other enzymes.

研究组 & 干预措施
VSL#3 probiotic preparation
30 mothers in the last 4 weeks of gestation and in the first month of breastfeeding will be given (after obtaining their informed consent) 1 sachet per day of probiotics (VSL#3) during the last four weeks of pregnancy and the first month of breastfeeding for four weeks under the usual fasting dosage scheme (1 sachet before meal).
干预措施: VSL#3 probiotic preparation (Dietary Supplement)
Placebo VSL#3
30 mothers in the last 4 weeks of gestation and in the first month of breastfeeding will be given (after obtaining their informed consent) a placebo comparable to VSL#3 during the last four weeks of pregnancy and the first month of breastfeeding for four weeks under the usual fasting dosage scheme (1 sachet/day, before meal)
干预措施: Placebo VSL#3 (Other)
结局指标
主要结局
Effect of VSL#3 probiotic administration on breast milk
时间窗: 2 months
Assessment of the effects of administration of a probiotic in the last four weeks of gestation and/or during the first month of lactation on the breast milk concentrations of cytokines (TGF-beta, IL-6, IL-10) and immunoglobulines (IGG, IGA, IGM) as well as metabolic profiles and the amount of probiotic species. A total of 30 mothers per arm is expected to be enrolled in the study. Interim analysis will be conducted upon completion of 9 patients per arm.
次要结局
- Assessment of sphingomyelinase concentration in breastmilk of mothers(2 months)
- Assessment of PAF hydrolysis in breastmilk of mothers(2 months)
- Assessment of fecal newborn microbiota(2 months)
