Individualized Fortification Based on Measured Macronutrient Content of Human Milk Improves Growth and Body Composition in Infants Born Less than 33 Weeks: A Mixed-Cohort Study. Nutrients 2023; 15:nu15061533. [PMID: 36986263 PMCID: PMC10052754 DOI: 10.3390/nu15061533] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2023] [Revised: 03/19/2023] [Accepted: 03/20/2023] [Indexed: 03/30/2023] Open
Abstract
The optimal method for human milk (HM) fortification has not yet been determined. This study assessed whether fortification relying on measured HM macronutrient content (Miris AB analyzer, Upsala, Sweden) composition is superior to fortification based on assumed HM macronutrient content, to optimize the nutrition support, growth, and body composition in infants born at <33 weeks' gestation. In a mixed-cohort study, 57 infants fed fortified HM based on its measured content were compared with 58 infants fed fortified HM based on its assumed content, for a median of 28 and 23 exposure days, respectively. The ESPGHAN 2010 guidelines for preterm enteral nutrition were followed. Growth assessment was based on body weight, length, and head circumference Δ z-scores, and the respective growth velocities until discharge. Body composition was assessed using air displacement plethysmography. Fortification based on measured HM content provided significantly higher energy, fat, and carbohydrate intakes, although with a lower protein intake in infants weighing ≥ 1 kg and lower protein-to-energy ratio in infants weighing < 1 kg. Infants fed fortified HM based on its measured content were discharged with significantly better weight gain, length, and head growth. These infants had significantly lower adiposity and greater lean mass near term-equivalent age, despite receiving higher in-hospital energy and fat intakes, with a mean fat intake higher than the maximum recommended and a median protein-to-energy ratio intake (in infants weighing < 1 kg) lower than the minimum recommended.

Abstract
PURPOSE OF REVIEW Preterm birth is one of the most pressing clinical problems in obstetrics and neonatology worldwide. One of the most sophisticated components of human milk is the proteome and a better understanding of it can lead to precision guides for feeding preterm infants. In this review, we will examine recent research focused on the human milk proteome and individualized protein fortification of human milk. RECENT FINDINGS In both preterm and term birth, the protein content in mother's own milk dropped rapidly in the early postnatal period. Preterm milk had a higher protein content and contained different protein and endogenous peptide compositions compared with term milk. The peptides in gastrointestinal fluids of preterm infants still need further investigation. Individualized fortification is more superior to standard fortification, but it only focuses on the total protein amount. There is no data concerning the composition and posttranslational modifications of proteins and endogenous peptides with fortification and their longterm effects. SUMMARY Comprehensive identification and characterization of the human milk proteome have led to the targeted breast milk fortification theory of preterm infant feeding and has also been enriched by clinical trials. However, to achieve fortification of key proteins and/or endogenous peptides, as standard clinical practice, requires additional studies. Future research should explore the long-term effect of protein fortification and pay more attention to quality rather than quantity in relation to infant body composition and growth outcomes.

Abstract
AIM To investigate the use of human milk fortifier (HMF) for very preterm infants (VPIs) and complications and nutritional status of VPIs due to various breast milk enhancement strategies among the Chinese population. METHODS VPIs with birth weight < 1,800 g and wholly or predominantly breastfed were assigned to the following fortification groups: no HMF, early HMF (adding HMF at an enteral volume of ≤ 80 ml·kg-1·day-1), middle HMF (adding HMF at an enteral volume of 80-100 ml·kg-1·day-1), and late HMF (adding HMF at an enteral volume of ≥100 ml·kg-1·day-1). The growth status and complications for various groups were evaluated. RESULTS We enrolled 985 VPIs, of which 847 VPIs (86.0%) received HMF, whereas 138 VPIs (14.0%) did not. The number of VPIs in the early, middle, and late fortification groups were 89 (9.0%), 252 (25.6%), and 506 (51.4%), respectively. The complete fortification of the early, middle, and late fortification groups was achieved in 13.2 ± 11.0, 13.8 ± 11.7, and 12.3 ± 13.0 days, respectively, without significant differences (p > 0.05). The groups did not exhibit significant differences in the incidence of feeding intolerance, necrotizing enterocolitis (Bell stage ≥ 2), late-onset sepsis, and metabolic bone diseases (p > 0.05). The middle fortification groups exhibited the fastest growth velocity and the least dramatic decrease in the Z-score of weight and length, and the lowest incidence of EUGR (35.7%), whereas the "no HMF" groups exhibited the slowest growth velocity and the largest decline in the Z-score, and the highest incidence of EUGR (61.6%). CONCLUSIONS The usage rate of HMF was relatively low among Chinese VPIs, fortification often occurred in the late feeding stage, and the time to reach complete fortification was long. Adding HMF and different breast milk enhancement strategies did not increase the incidence of feeding intolerance and necrotizing enterocolitis. The enteral volume of 80-100 ml·kg-1·day-1 with HMF addition led to increased growth in the weight and length and lower EUGR incidence, indicating that the addition of HMF at the specific feeding volume might be the best practice for promoting growth.

Abstract
Bronchopulmonary dysplasia (BPD) remains the most common severe complication of preterm birth, and nutrition plays a crucial role in lung growth and repair. A practical nutritional approach for infants at risk of BPD or with established BPD is provided based on a comprehensive literature review. Ideally, infants with BPD should receive a fluid intake of not more than 135-150 mL/kg/day and an energy intake of 120-150 kcal/kg/day. Providing high energy in low volume remains a challenge and is the main cause of growth restriction in these infants. They need a nutritional strategy that encompasses early aggressive parenteral nutrition and the initiation of concentrated feedings of energy and nutrients. The order of priority is fortified mother's own milk, followed by fortified donor milk and preterm enriched formulas. Functional nutrient supplements with a potential protective role against BPD are revisited, despite the limited evidence of their efficacy. Specialized nutritional strategies may be necessary to overcome difficulties common in BPD infants, such as gastroesophageal reflux and poorly coordinated feeding. Planning nutrition support after discharge requires a multidisciplinary approach to deal with multiple potential problems. Regular monitoring based on anthropometry and biochemical markers is needed to guide the nutritional intervention.

Abstract
OBJECTIVE Human milk (HM) has antibacterial properties due to the presence of immune-modulators, including lactoferrin (LF). This study will determine effect(s) of HM maturation, fortification, and storage conditions on LF levels and its antibacterial properties. STUDY DESIGN HM samples (n = 30) were obtained from preterm and term mothers. The LF levels were analyzed by ELISA, and the antibacterial activity was measured after inoculation with Escherichia coli. RESULTS The highest level of LF in preterm HM was observed in the first week of lactation. However, storage of preterm HM at 4°C decreased LF levels significantly. Both LF levels and antibacterial activity in preterm HM was lower compared with term HM, but significantly higher than donor HM even after HM-based fortification. LF supplementation of donor HM improved its antibacterial activity. CONCLUSION Preterm infants fed donor HM, formula, or stored HM at 4°C may benefits from LF supplementation to improve HM antibacterial properties. KEY POINTS · Milk LF levels vary with storage and maturity.. · Donor milk is deficient in LF even after adding HM-based fortification.. · Donor HM and formula fed infants may benefit from LF..
