- We hypothesised that feeding the probiotic Lactobacillus paracasei ssp. paracasei F19 (LF19) (dep. nr LMG P-17806) during weaning would program the metabolic and inflammatory profile and studied its association with previously assessed body composition. In a double-blind, placebo-controlled trial, 179 infants were randomised to daily feeding of cereals with or without LF19 10 8 CFU from 4 to 13 months of age. At age 8-9 years, 120 children were reassessed. Using high-sensitivity multiplex immunoassay technology and ELISA, we found that overweight/obese children had increased plasma C-peptide, plasminogen activator inhibitor-1, leptin and serum high-sensitivity C-reactive protein (hsCRP) after overnight fasting compared with normal weight children, independently of LF19. After excluding the obese, leptin and hsCRP were still increased, revealing an aberrant metabolic and inflammatory state already in overweight, pre-pubertal children. Higher body mass index z-score, sagittal abdominal diameter, truncal and total body fat % were associated with an aberrant metabolic and inflammatory profile, emphasising the need for early prevention strategies although no programming effect of LF19 was observed.

- PURPOSE: An aberrant gut microbiome has been suggested to contribute to the worldwide epidemic of obesity. In animal models, the probiotic Lactobacillus paracasei ssp. paracasei F19 (LF19) induced upregulation of genes involved in energy homoeostasis, reduced body fat and altered the serum (S) lipoprotein profile. In our previous report, feeding LF19 to infants during weaning impacted the global plasma metabolome. LF19 lowered palmitoleic acid, a monounsaturated fatty acid associated with hypertriglyceridemia and increased visceral adiposity. Therefore, we assessed if feeding LF19 from 4 to 13 months of age would have long-term effects on body composition, growth and metabolic markers.METHODS: Of 179 children included in our baseline study, 120 entered the follow-up at 8-9 years of age, n = 58 in the probiotic and n = 62 in the placebo group. Body composition was measured using dual energy X-ray absorptiometry. Anthropometrics of the child and accompanying parent(s) were assessed. S-lipids, insulin, glucose and transaminases were determined after overnight fasting.RESULTS: LF19 did not affect body mass index z-score, sagittal abdominal diameter, fat-free mass, fat mass index, truncal fat %, android or gynoid fat % and had no long-term impact on any of the assessed metabolic markers (p > 0.05).CONCLUSION: Feeding LF19 during infancy did not modulate body composition, growth or any of the assessed metabolic markers at school age. The steady increase in probiotic products targeting infants and children calls for long-term follow-up of initiated probiotic intervention studies.

- Background: Proteins and lipids of milk fat globule membrane (MFGM) and probiotics are immunomodulatory. We hypothesized that Lactobacillus paracasei ssp. paracasei strain F19 (F19) would augment vaccine antibody and T helper 1 type immune responses whereas MFGM would produce an immune response closer to that of breastfed (BF) infants.Objective: To compare the effects of supplementing formula with F19 or bovine MFGM on serum cytokine and vaccine responses of formula-fed (FF) and BF infants.Design: FF infants were randomized to formula with F19 (n = 195) or MFGM (n = 192), or standard formula (SF) (n = 194) from age 21±7 days until 4 months. A BF group served as reference (n = 208). We analyzed seven cytokines (n = 398) in serum at age 4 months using magnetic bead-based multiplex technology. Using ELISA, we analyzed anti-diphtheria IgG (n = 258) and anti-poliovirus IgG (n = 309) concentrations in serum before and after the second and third immunization, respectively.Results: Compared with SF, the F19 group had greater IL-2 and lower IFN-γ concentrations (p<0.05, average effect size 0.14 and 0.39). Compared with BF, the F19 group had greater IL-2, IL-4 and IL-17A concentrations (p<0.05, average effect size 0.42, 0.34 and 0.26, respectively). The MFGM group had lower IL-2 and IL-17A concentrations compared with SF (p<0.05, average effect size 0.34 and 0.31). Cytokine concentrations were comparable among the MFGM and BF groups. Vaccine responses were comparable among the formula groups.Conclusions: Contrary to previous studies F19 increased IL-2 and lowered IFN-γ production, suggesting that the response to probiotics differs across populations. The cytokine profile of the MFGM group approached that of BF infants, and may be associated with the previous finding that infectious outcomes for the MFGM group in this cohort were closer to those of BF infants, as opposed to the SF group. These immunomodulatory effects support future clinical evaluation of infant formula with F19 or MFGM.
