Does Early Fortification of Human Milk Decrease Time to Regain Birth Weight as Compared to Late Fortification Among Preterm Infants? - A Randomized Controlled Trial. Indian J Pediatr 2024:10.1007/s12098-024-05066-5. [PMID: 38416365 DOI: 10.1007/s12098-024-05066-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/31/2023] [Accepted: 02/01/2024] [Indexed: 02/29/2024]
Abstract
OBJECTIVES To compare the duration required to regain birth weight following early fortification of human milk vs. late fortification among preterm infants. METHODS This randomized controlled trial included hemodynamically stable 120 preterm infants (≤32 wk of gestation). The intervention and comparator groups received standard fortification with human milk fortifier when enteral feeds reached 30 ml/kg/d (early fortification) and 80 ml/kg/d (late fortification) respectively. Neonates in both the groups received feed increments as per standard NICU protocol. Anthropometric measurements (weight, length, and head circumference) at birth and during postnatal follow-up were done following standard precautions and plotted on the sex-specific Fenton growth charts. Primary outcome was the mean duration required to regain birth weight. Secondary outcomes included weight gain velocity, linear growth, increase in head circumference and occurrence of sepsis, feed intolerance and necrotizing enterocolitis. RESULTS Preterm neonates who received early fortification regained birth weight earlier compared to those in the late fortification group (10.13 ± 2.90 vs. 11.26 ± 3.06, p <0.05). The weight gain velocity, linear growth and increase in head circumference were better in the early fortification group. There was no increased risk of culture proven sepsis, feed intolerance and necrotizing enterocolitis in the early fortification group compared to late fortification. CONCLUSIONS Standard fortification with human milk fortifier when enteral feeds reach 30 ml/kg/d helps preterm neonates regain birth weight earlier. Early fortification is well tolerated and safe for the population studied.

Abstract
Multicomponent fortification is the standard of care to support short-term growth in preterm infants receiving human milk. There is no consensus regarding the optimal timing, method, or products used to fortify human milk. Both bovine milk-based and human milk-based human milk fortifiers are safe options, though increased fortification and enrichment may be needed to achieve adequate growth. Additional studies are needed to evaluate newer fortifier products and fortification strategies.

Abstract
BACKGROUND Human milk-based human milk fortifier (HMB-HMF) makes it possible to provide an exclusive human milk diet (EHMD) to very low birth weight (VLBW) infants in neonatal intensive care units (NICUs). Before the introduction of HMB-HMF in 2006, NICUs relied on bovine milk-based human milk fortifiers (BMB-HMFs) when mother's own milk (MOM) or pasteurized donor human milk (PDHM) could not provide adequate nutrition. Despite evidence supporting the clinical benefits of an EHMD (such as reducing the frequency of morbidities), barriers prevent its widespread adoption, including limited health economics and outcomes data, cost concerns, and lack of standardized feeding guidelines. METHODS Nine experts from seven institutions gathered for a virtual roundtable discussion in October 2020 to discuss the benefits and challenges to implementing an EHMD program in the NICU environment. Each center provided a review of the process of starting their program and also presented data on various neonatal and financial metrics associated with the program. Data gathered were either from their own Vermont Oxford Network outcomes or an institutional clinical database. As each center utilizes their EHMD program in slightly different populations and over different time periods, data presented was center-specific. After all presentations, the experts discussed issues within the field of neonatology that need to be addressed with regards to the utilization of an EHMD in the NICU population. RESULTS Implementation of an EHMD program faces many barriers, no matter the NICU size, patient population or geographic location. Successful implementation requires a team approach (including finance and IT support) with a NICU champion. Having pre-specified target populations as well as data tracking is also helpful. Real-world experiences of NICUs with established EHMD programs show reductions in comorbidities, regardless of the institution's size or level of care. EHMD programs also proved to be cost effective. For the NICUs that had necrotizing enterocolitis (NEC) data available, EHMD programs resulted in either a decrease or change in total (medical + surgical) NEC rate and reductions in surgical NEC. Institutions that provided cost and complications data all reported a substantial cost avoidance after EHMD implementation, ranging between $515,113 and $3,369,515 annually per institution. CONCLUSIONS The data provided support the initiation of EHMD programs in NICUs for very preterm infants, but there are still methodologic issues to be addressed so that guidelines can be created and all NICUs, regardless of size, can provide standardized care that benefits VLBW infants.

Supplementation of Mother's Own Milk with Preterm Donor Human Milk: Impact on Protein Intake and Growth in Very Low Birth Weight Infants-A Randomized Controlled Study. Nutrients 2023; 15:nu15030566.

Abstract
This randomized study investigates whether feeding very low birth weight (VLBW) infants with mother's own milk (MOM) supplemented with either preterm (PDM) or term donor milk (TDM), when MOM is insufficient, has a positive impact on infants' protein intake and growth. A hundred and twenty VLBW infants were randomized into two groups. Group A (43 infants) received MOM supplemented with PDM, whereas Group B (77 infants) was fed with MOM supplemented with TDM, for the first three weeks of life (donor milk period). Breast milk fortifier was added when milk feeds exceeded 50 mL/Kg/day. After the donor milk period, both groups were fed with formula when MOM was not available or the milk bank was unable to provide TDM. Protein intake was higher in Group A than in Group B at initiation of milk fortification (p = 0.006), as well as during the 3-week donor milk period (p = 0.023) and throughout hospitalization (p = 0.014). Moreover, Group A presented higher Δz-score for body weight (p = 0.019) and head circumference (p = 0.001) from birth to the end of donor milk period, and higher mean body weight at discharge (p = 0.047) compared to Group B. In conclusion, when donor milk is required, PDM positively impacts protein intake and growth in VLBW infants (NCT05675397).

Abstract
The benefits of feeding human milk to human infants are well-established. Preterm infants, particularly those born with very low birthweight (VLBW; <1,500 g), are a uniquely vulnerable population at risk for serious, life-threatening complications as well as disruptions in normal growth and development that can affect their lives into adulthood. Feeding VLBW preterm infants an exclusive human milk diet (EHMD) from birth that consists of the mother's own milk or donor human milk plus a nutritional fortifier made exclusively from human milk has been associated with a reduction in morbidity and mortality and improved early growth and developmental metrics. Preliminary evidence suggests that the health benefits of adopting an EHMD (or avoiding cow milk products) early in life may last into adulthood. This review briefly summarizes the history of breastfeeding and describes the available evidence on the benefits of an EHMD among VLBW preterm infants as well as the importance of high-quality manufacturing standards for producing safe and effective human milk-based products.

Abstract
An exclusive human milk diet (EHMD) has been shown to reduce health complications of prematurity in infants born weighing ≤1250 g compared with cow milk-based diets. Accordingly, the number of available human milk (HM)-based nutritional products continues to increase. Newly available products, and those reportedly soon to enter the market, include homogenized donor HM and homogenized HM-based fortifiers. Existing literature demonstrating the benefits of an EHMD, however, is limited to non-homogenized HM-based products. Herein, we summarize existing evidence on the impact of homogenization on HM, with a particular focus on changes to the macromolecular structure of the milk fat globule and the subsequent impact on digestion kinetics. We use these published data to create a conceptual framework for the potential implications of homogenized HM-based nutritional products on preterm infant health. Importantly, we underscore that the safety and efficacy of homogenized HM-based products warrant investigation.

Abstract
BACKGROUND/PURPOSE To evaluate the enteral feeding requirements, including caloric provisions, of infants with CDH in relation to growth patterns. METHODS A retrospective observational study was conducted on infants with CDH between August 2012 and March 2017. Electronic medical records were reviewed to extract detailed infant feeding data and anthropometric measurements at monthly intervals until discharge. Statistical methods of analysis included generalized linear models, Pearson correlation coefficient, Analysis of variance (ANOVA), Kruskal-Wallis, Wilcoxon rank sum, and Fisher's Exact tests. RESULTS Among 149 infants with CDH, 45% (n = 67) met criteria for malnutrition at discharge. Maternal human milk (HM) was initiated in 95% of infants (n = 142) and continued in 79% of infants (n = 118) at discharge. Overall, 50% received fortification of feeds, including 60% (n = 89) of formula fed infants compared to only 21% (n = 31) of HM fed infants (p<0.001). Infants fed formula had lower weight-for-length z-scores at discharge compared to those fed HM. CONCLUSIONS Infants receiving HM demonstrated improved growth compared to formula fed infants. However, higher calorie feeding regimens need to be initiated earlier to improve growth velocity. Prompt recognition of malnutrition and growth failure with aggressive supplementation may improve the overall growth of infants with CDH and has the potential to improve long term neurodevelopmental outcomes.

Abstract
Background Preterm human milk has advantages over preterm formula (PF), but it may compromise some functions after pasteurization. Objective To explore the effects of preterm donor milk (DM) on growth, feeding tolerance, and severe morbidity in very-low-birth-weight infants. Method This was a single-center, prospective cohort study that included 304 preterm infants weighing <1,500 g or of gestational age <32 weeks. If the mother's own milk was insufficient, the parents decided to use PF (n = 155) or DM (n = 149). The two groups were uniformly managed according to the standard NICU protocol. Growth parameters, feeding tolerance, and severe morbidity such as necrotizing enterocolitis, were compared between the two groups. Results The daily weight gain and weekly head growth in the DM group were not different from those in the PF group (P > 0.05). Feeding intolerance in the DM group was significantly lower than that in PF group (P < 0.05), and parenteral nutrition time and hospitalization time were also shorter than that in the PF group (P < 0.05). Moreover, the incidence of necrotizing enterocolitis and sepsis was also significantly lower in the DM group (P < 0.05). Conclusion The study indicated that preterm DM does not affect the growth of very-low-birth-weight infants. Further, it significantly reduces feeding intolerance, helps achieve full enteral feeding early, and has protective effects against necrotizing enterocolitis and sepsis. Thus, compared with formula, preterm DM can lower the rate of infection in preterm infants and is worthy of promotion.

Abstract
AIM To determine the growth and prevalence of extrauterine growth restriction (EUGR) in extremely low birth weight (ELBW) infants receiving enteral-only nutrition in a resource-restricted (RR) environment. METHODS Information on nutritional intake, provided largely from fortified breastmilk, was collected retrospectively for 72 ELBW (<1000 g) infants admitted to Tygerberg Hospital, Cape Town, South Africa over a 1 year period. Anthropometric data for the first 49 postnatal days were compared to gender-specific INTERGROWTH-21st standards. RESULTS Full enteral feeds (150 ml/kg) were reached by Day 10-14 with energy >100 Kcal/kg/day from Day 10, and protein >3.5 mg/kg/day from Day 14, onwards. Growth velocity remained below 15 g/kg/day at Day 49. INTERGROWTH-21st Z-scores decreased from -0.8 ± 1.1 at birth to -2.4 ± 1.5 at Day 49. Adequate weight growth velocity (≥15 g/kg/day) was associated with maternal hypertension, completed antenatal steroids, caesarean section delivery and small for gestational age status. CONCLUSION This is the first study to evaluate growth of ELBW infants in a RR setting where enteral-only nutrition, principally from fortified breastmilk, was the primary feeding option. The incidence of EUGR, although high, was similar to the incidence in well-resourced settings, where total parenteral nutrition is routinely provided. Lay summaryExtra-uterine growth restriction (EUGR) is high in extremely low birth weight infants receiving enteral-only nutrition. However, EUGR rates are similar to infants receiving parenteral nutrition. Despite developmental immaturity, it is possible for these infants to achieve fetal growth rates. More aggressive feeding and fortification strategies may be necessary and will need to be balanced against the risk and fear of necrotizing enterocolitis. Enteral-only feeding regimens, especially in resource-restricted environments, should be audited regularly to ensure provision of feeds with the most optimal protein, and protein to energy ratios possible.

Abstract
BACKGROUND Uncertainty exists about the optimal point at which multi-component fortifier should be added to human milk for promoting growth in preterm infants. The most common practice is to start fortification when the infant's daily enteral feed volume reaches 100 mL/kg body weight. Another approach is to commence fortification earlier, in some cases as early as the first enteral feed. Early fortification of human milk could increase nutrient intake and growth rates but may increase the risk of feed intolerance and necrotising enterocolitis (NEC). OBJECTIVES To assess effects on growth and safety of early fortification of human milk versus late fortification in preterm infants To assess whether effects vary based upon gestational age (≤ 27 weeks; 28 to 31 weeks; ≥ 32 weeks), birth weight (< 1000 g; 1000 to 1499 g; ≥ 1500 g), small or appropriate for gestational age, or type of fortifier (bovine milk-based human milk fortifier (HMF); human milk-based HMF; formula powder) SEARCH METHODS: We used the standard strategy of Cochrane Neonatal to search the Cochrane Central Register of Controlled Trials (CENTRAL; 2019, Issue 8); OVID MEDLINE (R) and Epub Ahead of Print, In-Process & Other Non-Indexed Citations, Daily and Versions (R) (1946 to 15 August 2019); MEDLINE via PubMed (1 August 2018 to 15 August 2019) for the previous year; and the Cumulative Index to Nursing and Allied Health Literatue (CINAHL) (1981 to 15 August 2019). We searched clinical trials databases and reference lists of included studies. SELECTION CRITERIA We included randomised controlled trials that compared early versus late fortification of human milk in preterm infants. We defined early fortification as fortification started at < 100 mL/kg/d enteral feed volume or < 7 days postnatal age, and late fortification as fortification started at ≥ 100 mL/kg/d feeds or ≥ 7 days postnatal age. DATA COLLECTION AND ANALYSIS Both review authors assessed trial eligibility and risk of bias and independently extracted data. We analysed treatment effects in individual trials, and we reported risk ratio (RR) for dichotomous data and mean difference (MD) for continuous data, with respective 95% confidence intervals (CIs). We used the GRADE approach to assess the certainty of evidence. MAIN RESULTS We included two trials with a total of 237 infants. All participants were very low birth weight infants (birth weight < 1500 g). Early fortification was started at 20 mL/kg/d enteral feeds in one study and 40 mL/kg/d in the other study. Late fortification was started at 100 mL/kg/d feeds in both studies. One study used bovine milk-based fortifier, and the other used human milk-based fortifier. Meta-analysis showed that early fortification may have little or no effect on growth outcomes including time to regain birth weight (MD -0.06 days, 95% CI -1.32 to 1.20 days), linear growth (MD 0.10 cm/week, 95% CI -0.03 to 0.22 cm/week), or head growth (MD -0.01 cm/week, 95% CI -0.07 to 0.06 cm/week) during the initial hospitalisation period. Early fortification may have little or no effect on the risk of NEC (MD -0.01, 95% CI -0.07 to 0.06). The certainty of evidence was low for these outcomes due to risk of bias (lack of blinding) and imprecision (small sample size). Early fortification may have little or no effect on incidence of surgical NEC, time to reach full enteral feeds, extrauterine growth restriction at discharge, proportion of infants with feed interruption episodes, duration of total parenteral nutrition (TPN), duration of central venous line usage, or incidence of invasive infection, all-cause mortality, and duration of hospital stay. The certainty of evidence was low for these outcomes due to risk of bias (lack of blinding) and imprecision (small sample size). We did not have data for other outcomes such as subsequent weight gain after birth weight is regained, parenteral nutrition-associated liver disease, postdischarge growth, and neurodevelopmental outcomes. AUTHORS' CONCLUSIONS Available evidence is insufficient to support or refute early fortification of human milk in preterm infants. Further large trials would be needed to provide data of sufficient quality and precision to inform policy and practice.

Abstract
This systematic review and meta-analysis assessed the effects of early fortification (EF) versus late fortification (LF) of breast milk (BM) on growth of preterm infants. Randomized and quasi-randomized controlled trials (RCTs) dealing with the effects of EF versus LF on growth parameters, incidence of adverse events, and duration of hospital stay in preterm infants were included. Data were pooled using the RevMan 5.3 software. Quality of evidence for predefined outcomes was analyzed by GRADE. Available evidence (3 RCTs, 309 preterm infants) showed no statistically significant difference between EF and LF of BM for any of the growth parameters-weight (standardized mean difference (SMD) 0.13; 95% confidence interval (CI) - 0.09, 0.36); length (SMD 0.02; 95% CI - 0.20, 0.25); and head circumference (SMD - 0.10; 95% CI - 0.33, 0.12). Total parenteral nutrition days were similar. Duration of hospital stay was significantly higher with EF (MD 4.29; 95% CI 0.84, 7.75) with a trend of non-significant increase in feed intolerance and necrotizing enterocolitis (NEC).Conclusion: Very low quality evidence did not find any significant difference in growth parameters of preterm infants in association with EF or LF of BM. A significant increase in hospital stay and non-significant increase in feed intolerance and NEC were associated with EF.PROSPERO registration number: CRD42019139235What is Known:• Fortification of breast milk with essential macro- and micronutrients is necessary for optimization of nutrition in preterm infants.• There is no consensus regarding the breast milk feeding volume at which fortification should be initiated.What is New:• Very low quality evidence showed no significant difference between early and late fortification of breast milk on growth parameters of preterm infants.• Early fortification was associated with non-significant increase in feed intolerance and necrotizing enterocolitis and a significant increase in hospital stay.
