Abstract

Introduction Vitamin B12 plays a role during pregnancy in maintaining folate metabolism. Together with folate and vitamin B6, B12 is involved as a coenzyme in DNA synthesis and various methylation reactions in developing embryos. This study aims to compare plasma folate, vitamin B6 and B12 blood levels with respect to the presence of probiotic strain Bifidobacterium animalis subsp. lactis HNO19 (DR10TM) among pregnant women in Indonesia. Methods: This study is part of a larger study entitled ?Effects of Bifidobacterium animalis subsp. lactis HNO19 (DR10TM), inulin, and micronutrient fortified milk on fecal DR10TM, immune markers, and maternal micronutrients among Indonesian pregnant women.? Further analyses were performed using independent-t test or Mann Whitney test, GLM-repeated measures and chi-square test, to compare folate, vitamin B6 and B12 intake and blood concentration during pregnancy with presence (n=22) and absence (n=55) subjects of fecal DR10TM at third trimester. Results: At the first trimesters there was no difference in plasma vitamin B6 and vitamin B12 levels between the two groups, based on the presence or absence of fecal DR10TM. However, at the second and third trimester, vitamin B6 blood concentration (p=0.034 and p=0.001) and vitamin B12 blood concentrations at the third trimester (p=0.035) were significantly higher in the fecal DR10TM positive group, while having a similar vitamin B6 and B12 intake. Conclusion: Consumption of pre- and probiotics during the periconceptional period may be a useful strategy for improving maternal vitamin B?s vitamins, especially vitamin B6 and B12 status and therefore provide benefits for the offspring?s quality of life.

Abstract

Human milk contains higher levels of gangliosides when compared to infant formula. Gangliosides play a role in neuronal growth, migration, maturation, sinaptogenesis, and myelination. Seven of the identified gangliosides (GM1, GM2, GM3, GD3, GD1a, GD1b, and GT1b) are dominant gangliosides with different specific functions. Thus, the aim of the study was to understand the effects of ganglioside-enhanced diet and to compare the spectrum patterns of those seven classes of serum gangliosides in infants consuming standard infant formula (IF group), ganglioside-fortified infant formula (GA group) and exclusive breastfeeding (BF group). This study used liquid chromatography–mass spectrometry (LC-MS) method. This was a prospective study involving 30 infants in IF group, 29 in GA group and 32 in BF group. Subject recruitment was performed using consecutive admission  approach from March 2008 to February 2009 in Bandung. Statistical analyses using Wilcoxon test showed that there was a significant change in the spectrum patterns of GD3, GM1, GM2 and GT1b in IF group; of GD1a, GM1 and GM2 in GA group and of GD1a, GD1b, GM1 and GM3 in BF group. It is concluded that ganglioside-enriched diet extends spectrum patterns of gangliosides especially in seven of them, i.e. GM1, GM2, GM3, GD3, GD1a, GD1b, and GT1b, in 6-month old infants.
