lactoferrin and Neurodevelopmental-Disorders

Central nervous system (CNS) diseases are currently one of the major health issues around the world. Most CNS disorders are characterized by high oxidative stress levels and intense inflammatory responses in affected tissues. Lactoferrin (Lf), a multifunctional iron-binding glycoprotein, plays a significant role in anti-inflammatory, antibacterial, antiviral, reactive oxygen species (ROS) modulator, antitumor immunity, and anti-apoptotic processes. Previous studies have shown that Lf is abnormally expressed in a variety of neurological diseases, especially neurodegenerative diseases. Recently, the promotion of neurodevelopment and neuroprotection by Lf has attracted widespread attention, and Lf could be exploited both as an active therapeutic agent and drug nanocarrier. However, our understanding of the roles of Lf proteins in the initiation or progression of CNS diseases is limited, especially the roles of Lf in regulating neurogenesis. This review highlights recent advances in the understanding of the major pharmacological effects of Lf in CNS diseases, including neurodegenerative diseases, cerebrovascular disease, developmental delays in children, and brain tumors.

To determine the effect of bovine lactoferrin on prevention of late-onset sepsis (LOS) and neurodevelopment delay.. Randomized, double-blind, controlled trial in neonates with a birth weight of 500-2000 g in 3 neonatal units in Lima, Peru, comparing bovine lactoferrin 200 mg/kg/day with placebo administered for 8 weeks. The primary outcome was the first episode of culture-proven LOS or sepsis-associated death. Neurodevelopment delay was assessed by the Mullen Scales at 24 months corrected age.. Of the 414 infants enrolled, 209 received bovine lactoferrin and 205 received placebo. LOS or sepsis-associated death occurred in 22 infants (10.5%) in the bovine lactoferrin group vs 30 (14.6%) in the placebo group; there was no difference after adjusting for hospital and birth weight; hazard ratio 0.73 (95% CI, 0.42-1.26). For infants with birth weights of <1500 g the hazard ratio was 0.69 (95% CI, 0.39-1.25). The mean age-adjusted normalized Mullen composite score at 24 months was 83.3 ± 13.6 in the bovine lactoferrin group vs 82.6 ± 13.1 in the placebo group. Growth outcomes and rehospitalization rates during the 2-year follow-up were similar in both groups, except for significantly less bronchiolitis in the bovine lactoferrin group (rate ratio, 0.34; 95% CI, 0.14-0.86).. Supplementation with bovine lactoferrin did not decrease the incidence of sepsis in infants with birth weights of <2000 g. Growth and neurodevelopment outcomes at 24 months of age were similar. Neonatal bovine lactoferrin supplementation had no adverse effects.. ClinicalTrials.gov: NCT01525316.

To evaluate neurodevelopment, growth, and health outcomes in infants receiving bovine milk fat globule membrane (MFGM) and lactoferrin in infant formula.. Healthy term infants were randomized to a cow's milk-based infant formula or MFGM + LF (a similar infant formula, with an added source of bovine milk fat globule membrane [bMFGM; whey protein-lipid concentrate, 5 g/L] and bovine lactoferrin [0.6 g/L]) through 365 days of age. The Bayley Scales of Infant Development, 3rd edition cognitive composite score at day 365 was the primary outcome. Secondary outcomes included tolerance measures through day 365, additional neurodevelopmental and language outcomes, growth, and medically confirmed adverse events through day 545.. Of 451 infants enrolled (control, 228; MFGM + LF, 223), 291 completed study feeding and Bayley-III testing at day 365 (control, 148; MFGM + LF, 143). The mean cognitive (+8.7), language (+12.3), and motor (+12.6) scores were higher (P < .001) for the MFGM + LF group; no differences were observed at day 545. Global development scores from day 120 to day 275 and attention at day 365 were significantly improved. Few group differences in day 545 neurodevelopmental outcomes were detected, however scores of some subcategories of the MacArthur-Bates Communicative Development Inventories were higher (P < .05) in the MFGM + LF group. The overall incidence of respiratory-associated adverse events and diarrhea were significantly lower for the MFGM + LF group through day 545.. Infants receiving formula with added bovine MFGM and bovine lactoferrin had an accelerated neurodevelopmental profile at day 365 and improved language subcategories at day 545. Formulas were associated with age-appropriate growth and significantly fewer diarrhea and respiratory-associated adverse events through 545 days of age.
