[Literature library] Efficacy of myelin nutrient blend on developmental myelination

Study Design

• An ongoing, prospective, longitudinal, two-center, double-blind, randomized controlled investigational trial in neurotypical term-born infants in the USA
   

Subject and Intervention

Control group (n = 39),

• Fed a bovine milk-based, alpha-lactalbumin enriched infant formula with a standard whey protein concentrate
   

Investigational group (n = 42),

• Fed a bovine milk-based, alpha-lactalbumin enriched infant formula with a processed whey protein concentrate containing higher levels of SM and phospholipids, supplemented with a blend of DHA, AA, iron, vitamin B12 and folic acid
   

Study Duration

• From enrollment (2-5 weeks of life) to 12 months of life with follow-up assessments up to 2 years of life
• Five clinical visits during intervention period at 6 ± 1 week, 3 months ± 2 weeks, 6 months ± 2 weeks, 9 months ± 2 weeks and 12 months ± 2 weeks of life
• Two follow-up visits at 18 months ± 3 weeks and 24 months ± 4 weeks of life
• Myelination was measured in magnetic resonance imaging (MRI) at 3 months and 6 months
   

Results*

Myelin structure,

• At 3 months, T1 values for occipital and parietal lobe were significantly decreased in the investigational over the control group
• At 6 months, T1 values for occipital and temporal lobe were significantly decreased in the investigational over the control group
• No significant differences were found for T2 scans at both 3 months and 6 months of age
   

Myelin volume,

• Myelin water fraction (MWF) was measured for myelin volume in the study
• At 3 months, MWF of the temporal lope was statistically larger in the investigational over the control group
• At 6 months, MWF of the whole brain, cerebellum, parietal, occipital, and temporal lobe were statistically larger in the investigational over the control group
   

Rate of myelination,

• Longitudinal MWF slopes for investigational group were significantly steeper in corpus callosum (CC) body (p = 0.025), CC genu (p = 0.016), CC splenium (p = 0.017), temporal lobes (p = 0.045), parietal lobes (p = 0.012), occipital lobes (p = 0.0511), and whole brain (p = 0.013) when compared with control
   

Conclusion

The efficacy of the myelin nutrient blend on developmental myelination in the first year of life was demonstrated
