ABSTRACT: The breast milk bioactive substances such as adiponectin, have a presumably long-term impact upon the health and well-being of a child.
To determine the impact of probiotic-supplemented dietary counseling during pregnancy on colostrum adiponectin concentration.
Altogether 256 pregnant women were randomized into three study groups: dietary intervention with probiotics (diet/probiotics) or with placebo (diet/placebo) and a control group (control/placebo). The intervention group received dietary counseling provided by a nutritionist, the main focus being the amount and the type of dietary fat. The probiotics used were Lactobacillus rhamnosus GG and Bifidobacterium lactis in combination. Dietary intake was evaluated by food records at every trimester of pregnancy. Breast milk samples were collected after birth (colostrum) for adiponectin concentration analysis (n=181).
The dietary intervention increased the colostrum adiponectin concentration (ng/mL, geometric mean [95% CI]), the difference being significant when comparing to the control group; 12.7 [10.6-29.7] vs. 10.2 [9.9-13.2], P=0.024. Maternal weight gain during pregnancy (kg) correlated inversely with colostrum adiponectin concentration; β (SE)=-1.7 (0.1), P=0.020, and gestational diabetes mellitus was associated with the likelihood of adiponectin concentration falling into the lowest quartile; OR 2.36, 95% CI 1.1-3.2, P=0.028.
In showing that the colostrum adiponectin concentration is markedly dependent on maternal diet and nutritional status during pregnancy, and considering that colostrum adiponectin has potential effects on metabolism, nutrition, and immune function in the neonates, the results of this study underscore the importance of the metabolic homeostasis of the mother for the child's initial nutritional environment.

ABSTRACT: The perinatal nutritional environment impacts upon the health and well-being of mother and child also in the long term. The aim of the present study was to determine the safety and efficacy of perinatal probiotic-supplemented dietary counselling by evaluating pregnancy outcome and fetal and infant growth during the 24 months' follow-up. Altogether, 256 women were randomised at their first trimester of pregnancy into a control and a dietary intervention group. The intervention group received intensive dietary counselling provided by a nutritionist and were further randomised, double-blind to receive probiotics (Lactobacillus rhamnosus GG and Bifidobacterium lactis Bb12; diet/probiotics) or placebo (diet/placebo). Firstly, probiotic intervention reduced the frequency of gestational diabetes mellitus (GDM); 13 % (diet/probiotics) v. 36 % (diet/placebo) and 34 % (control); P = 0.003. Secondly, the safety of this approach was attested by normal duration of pregnancies with no adverse events in mothers or children. No significant differences in prenatal or postnatal growth rates among the study groups were detected. Thirdly, distinctive effects of the two interventions were detected; probiotic intervention reduced the risk of GDM and dietary intervention diminished the risk of larger birth size in affected cases; P = 0.035 for birth weight and P = 0.028 for birth length. The results of the present study show that probiotic-supplemented perinatal dietary counselling could be a safe and cost-effective tool in addressing the metabolic epidemic. In view of the fact that birth size is a risk marker for later obesity, the present results are of significance for public health in demonstrating that this risk is modifiable.

ABSTRACT: To investigate whether birch pollen allergy symptoms are linked with gut microbiota changes and whether probiotics have an effect on these.
Forty seven children with confirmed birch pollen allergy were randomized to receive either a probiotic combination of Lactobacillus acidophilus (L. acidophilus) NCFM (ATCC 700396) and Bifidobacterium lactis (B. lactis) Bl-04 (ATCC SD5219) or placebo in a double-blind manner for 4 mo, starting prior to onset of the birch pollen season. Symptoms were recorded in a diary. Blood samples were taken for analysis of cytokines and eosinophils. Fecal samples were analysed for microbiota components, calprotectin and IgA. Nasal swabs were taken for analysis of eosinophils.
The pollen season induced a reduction in Bifidobacterium, Clostridium and Bacteroides which could not be prevented by the probiotic intervention. During the intervention, significantly higher numbers of B. lactis 11.2 x 10(7) +/- 4.2 x 10(7) vs 0.1 x 10(7) +/- 0.1 x 10(7) bacteria/g feces (P < 0.0001) and L. acidophilus NCFM 3.5 x 10(6) +/- 1.3 x 10(6) vs 0.2 x 10(6) +/- 0.1 x 10(6) bacteria/g feces (P < 0.0001) were observed in the probiotic group compared to the placebo group. During May, there was a tendency for fewer subjects, (76.2% vs 95.2%, P = 0.078) to report runny nose, while during June, fewer subjects, 11.1% vs 33.3%, reported nasal blocking in the probiotics group (P = 0.101). Concomitantly, fewer subjects in the probiotic group had infiltration of eosinophils in the nasal mucosa compared to the placebo group, 57.1% vs 95% (P = 0.013). Eye symptoms tended to be slightly more frequent in the probiotic group, 12.5 d [interquartile range (IQR) 6-18] vs 7.5 d (IQR 0-11.5) (P = 0.066) during May. Fecal IgA was increased in the placebo group during the pollen season; this increase was prevented by the probiotics (P = 0.028).
Birch pollen allergy was shown to be associated with changes in fecal microbiota composition. The specific combination of probiotics used was shown to prevent the pollen-induced infiltration of eosinophils into the nasal mucosa, and indicated a trend for reduced nasal symptoms.

ABSTRACT: It is not known whether trace amounts of proteins that may remain in cereal-starch-derived food ingredients even after food processing can trigger allergic symptoms in cereal-allergic individuals. The aim of this study was to find out if barley starch syrup causes allergic reactions in patients with allergy to wheat, barley, rye or oats. Fifteen children with allergy to these cereals, confirmed by double-blind placebo-controlled food challenge (DBPCFC), were selected for the study. When exposed to cereals, seven of the children (47%) showed immediate type reactions, such as urticaria, rash or anaphylaxis. Eight of the children (53%) showed delayed type reactions, such as deterioration of atopic dermatitis or diarrhoea. The fifteen children with allergy to cereals were exposed to barley starch syrup in DBPCFC and none of them showed any objective signs of allergy. On skin-prick tests (SPT), five of the children (33.3%) showed a positive (>or= 3 mm) reaction to at least one of the cereals but none of them to barley starch syrup. This study confirmed with 98% confidence that at least 90% of the patients with verified allergy to cereals will not react with allergic symptoms to barley starch syrup.
