RESUMO

OBJECTIVE: The aim of this study was to investigate the effects of soybean, medium-chain triacylglycerols (MCTs), olive oil, and fish oil (SMOF) on short-term clinical outcomes, physical growth, and extrauterine growth retardation (EUGR) in very preterm infants. METHODS: This was a multicenter retrospective cohort study of very preterm infants hospitalized in neonatal intensive care units at five tertiary hospitals in China between January 2021 and December 2021. According to the type of fat emulsion used in parenteral nutrition (PN), eligible very preterm infants were divided into the MCTs/long-chain triacylglycerol (MCT/LCT) group and SMOF group. Change in weight z-score (weight Δz) between measurements at birth and at 36 wk of postmenstrual age or at discharge, the incidence of EUGR, and short-term clinical outcomes between the two groups were compared and analyzed. RESULTS: We enrolled 409 very preterm infants, including 205 in the MCT/LCT group and 204 in the SMOF group. Univariate analysis showed that infants in the SMOF group had significantly longer duration of invasive mechanical ventilation and PN, longer days to reach total enteral nutrition, and a higher proportion of maximum weight loss than those in MCT/LCT group (all P < 0.05). After adjusting for the confounding variables, multifactorial logistic regression analysis of short-term clinical outcomes showed that SMOF had protective effects on PN-associated cholestasis (odds ratio [OR], 0.470; 95% confidence interval [CI], 0.266-0.831) and metabolic bone disease of prematurity (OR, 0.263; 95% CI, 0.078-0.880). Additionally, SMOF was an independent risk factor for lower weight growth velocity (ß = -0.733; 95% CI, -1.452 to -0.015) but had no effect on the incidence of EUGR (OR, 1.567; 95% CI, 0.912 to -2.693). CONCLUSION: Compared with MCT/LCT, SMOF can reduce the risk for PN-associated cholestasis and metabolic bone disease of prematurity in very preterm infants and has a negative effect on growth velocity but has no effect on the incidence of EUGR.

RESUMO

BACKGROUND: Human milk for very preterm infants need fortification for optimal growth and development but the optimal fortification product remains to be identified. AIMS: To investigate feasibility, safety and preliminary efficacy on growth and blood biochemistry when using intact bovine colostrum (BC) as a fortifier to human milk in very preterm infants. METHODS: In an open-label, multicenter, randomized controlled pilot trial (infants 26-31 weeks' gestation), mother's own milk or donor human milk was fortified with powdered BC (n = 115) or a conventional fortifier (CF, bovine-milk-based, n = 117) until 35 weeks' postmenstrual age. Fortifiers and additional micronutrients were added to human milk according to local guidelines to achieve optimal growth (additional protein up to +1.4 g protein/100 mL human milk). Anthropometry was recorded weekly. Clinical morbidities including necrotizing enterocolitis (NEC) and late-onset sepsis (LOS) were recorded. Clinical biochemistry included plasma amino acid (AA) levels to assess protein metabolic responses to the new fortifier. RESULTS: A total of 232 infants, gestational age (GA) 28.5 ± 1.4 (weeks + days), fulfilled inclusion criteria. Birthweight, GA and delta Z scores from birth to end of intervention on weight, length or head circumference did not differ between groups, nor between the subgroups of small for gestational age infants. Likewise, incidence of NEC (BC: 3/115 vs. CF: 5/117, p = 0.72, unadjusted values), LOS (BC: 23/113 vs. CF: 14/116, p = 0.08) and other morbidities did not differ. BC infants received more protein than CF infants (+10%, p < 0.05) and showed several elevated AA levels (+10-40%, p < 0.05). CONCLUSION: Infants fortified with BC showed similar growth but received more protein and showed a moderate increase in plasma AA-levels, compared with CF. Adjustments in protein composition and micronutrients in BC-based fortifiers may be required to fully suit the needs for very preterm infants.

RESUMO

OBJECTIVES: To assess effects of enteral "low" dose (daily doses of ≤10 000 international unit) vitamin A supplementation compared with no vitamin A supplementation in human milk-fed preterm and low birth weight (LBW) infants. DATA SOURCES: Cochrane Central Register of Controlled Trials; Medline, Embase, Scopus, Web of Science, CINAHL from inception to 16 March 2021. STUDY SELECTION: Randomized trials were screened. Primary outcomes were mortality, morbidity, growth, neurodevelopment. Secondary outcomes were feed intolerance and duration of hospitalization. We also assessed the dose and timing of vitamin A supplementation. Data were extracted and pooled with fixed and random-effects models. RESULTS: Four trials including 800 very LBW <1.5 kg or <32 weeks' gestation infants were found. At latest follow-up, we found little or no effect on: mortality, sepsis, bronchopulmonary dysplasia, retinopathy of prematurity, duration of hospitalisation. However, we found a increased level of serum retinol mean difference of 4.7 µg/ml (95% CI 1.2 to 8.2, I2 =0.00%, one trial, 36 participants,). Evidence ranged from very low to moderate certainty. There were no outcomes reported for length, head circumference or neurodevelopment. LIMITATIONS: Heterogeneity and small sample size in the included studies. CONCLUSIONS: Low-dose vitamin A increased serum retinol concentration among very LBW and very preterm infants but had no effect on other outcomes. More trials are needed to assess effects on clinical outcomes and to assess effects in infants 1.5 to 2.4 kg or 32 to 26 weeks' gestation.

RESUMO

OBJECTIVE: To determine postdischarge iron status and associated factors in very preterm infants. STUDY DESIGN: A retrospective cohort study was conducted through a provincial database on all very preterm infants born in Nova Scotia between 2005 and 2018. As a standard of care, all infants received prophylactic iron supplements starting at 2-4 weeks of chronological age and were tested for iron deficiency at 4 or 6 months corrected age. Iron deficiency was defined as serum ferritin <20 g/L at 4 months or <12 g/L at 6 months. Multivariate logistic regression analysis identified factors associated with iron deficiency. RESULTS: Among 411 infants, 132 (32.1%) had iron deficiency and 11 (2.7%) had iron deficiency anemia. The prevalence of iron deficiency decreased over time, from 37.6% in 2005-2011 to 25.8% in 2012-2018. Gestational hypertension in the mother (P = .01) and gestational age <27 weeks (P = .02) were independent risk factors for iron deficiency. In addition, the odds of iron deficiency were lower in the mixed-fed group (ie, with breast milk and formula combined) compared with the exclusive formula-fed group (P = .01). CONCLUSIONS: Iron deficiency was prevalent in 32% of the very preterm infants despite early iron prophylaxis. These results demonstrate the importance of monitoring iron stores during preterm follow-up. Information about risk factors is important to mitigate iron deficiency in very preterm infants.

RESUMO

BACKGROUND & AIMS: Early electrolyte and mineral imbalances have emerged as a conspicuous problem in very preterm babies since the revision of nutrition guidelines and the eventual implementation of early aggressive parenteral nutrition (PN). We opted to carry out a study with the introduction of phosphorus as sodium glycerophosphate in PN from the first day onward to reveal the impact on serum phosphorus and calcium levels following the surge in the incidence of hypercalcemia and hypophosphatemia. METHODS: In this single-center, prospective, observational cohort study, inborn babies <32 gestational weeks and <1500 g between August 2017 and July 2018 were enrolled consecutively. Infants born in the first 6-month of this period were initiated PN (Early phosphorus group) containing phosphorus (1 mmol P as sodium glycerophosphate/100 ml PN) immediately after birth, and in the latter six-months, mineral-free standard PN (Control group) was commenced up until 48 h of life. Parenteral nutritional prescriptions of both groups were similar in terms of macro and micronutrient intakes except for early phosphorus, calcium, and sodium. Serum mineral and electrolyte levels were measured on Days 1-3-7 and compared between the groups. The primary outcome was the presence of hypophosphatemia in the first week of life. The secondary outcome was hypercalcemia, preterm morbidity, and mortality. RESULTS: A total of 261 infants were included in this study. There were 130 babies in Early phosphorus group and 131 in control group. Gestational ages (28.79 ± 2.1 vs 28.46 ± 2.2 weeks, respectively) and birth weights (1138 ± 273 vs 1090 ± 274 g, respectively) were similar in the groups. Mean serum phosphorus levels were higher on all days in Early phosphorus group (p < 0.001). Early phosphorus group had a lower incidence of hypophosphatemia on days 1-3 and 7 (p < 0.001). The percentage of hypercalcemic infants was significantly lower in Early phosphorus group on day 3 (p < 0.001). No difference was noted in terms of hypernatremia in the groups. CONCLUSIONS: Adding phosphorus to PN in the first hours of life reduced the frequency of hypophosphatemia and hypercalcemia without any surge in hypernatremia or morbidity. Nutrition guidelines need to be revised accordingly in terms of early mineral/electrolyte supplementation.

RESUMO

OBJECTIVE: This study aimed to investigate whether umbilical cord milking (UCM) prevents and controls anemia in preterm infants, as compared with immediate cord clamping (ICC). STUDY DESIGN: Pregnant women delivering at <34 weeks' gestation in four hospitals were randomly assigned to undergo UCM or ICC from July 2017 to June 2019. Hematological parameters and iron status were collected and analyzed as primary outcomes at 24 hours, 1 week, 2 weeks, and 6 months after delivery. RESULTS: Neonates receiving UCM had significant higher levels of hemoglobin (Hb), hematocrit, and serum iron (p < 0.05). Lower prevalence of anemia and lower need for transfusions were noted in UCM group. Although UCM was associated with prolonged duration of phototherapy, the maximum levels of bilirubin were similar between two groups (p > 0.05). CONCLUSION: UCM is an effective intervention to help preterm infants experience less anemia with the potential to increase blood volume, as seen by higher Hb levels and more enhanced iron stores.

RESUMO

Premature infants are born prior to a critical window of rapid placental nutrient transfer and fetal growth-particularly brain development-that occurs during the third trimester of pregnancy. Subsequently, a large proportion of preterm neonates experience extrauterine growth failure and associated neurodevelopmental impairments. Human milk (maternal or donor breast milk) is the recommended source of enteral nutrition for preterm infants, but requires additional fortification of macronutrient, micronutrient, and energy content to meet the nutritional demands of the preterm infant in attempts at replicating in utero nutrient accretion and growth rates. Traditional standardized fortification practices that add a fixed amount of multicomponent fortifier based on assumed breast milk composition do not take into account the considerable variations in breast milk content or individual neonatal metabolism. Emerging methods of individualized fortification-including targeted and adjusted fortification-show promise in improving postnatal growth and neurodevelopmental outcomes in preterm infants.

RESUMO

The health benefits of bovine colostrum have extensively been studied, including immune effects mediated by immunoglobulins, lactoferrin, and casein, as well as by certain growth factors. Some of these effects are not directly related to the absorption of proteins from the intestinal tract. The ingestion of BC can modulate the function of subsets of lymphocytes, macrophages, and dendritic cells and increase regulatory cytokines such as interleukin 10. In this review, we predominantly focused on evidence from human studies on benefits in health and disease. This review highlights that clear evidence of the prevention of infectious diseases in pre-term infants such as necrotizing enterocolitis, neonatal sepsis or prevention of cancer metastasis is lacking. This is clearly an area where translational science has to be strengthened, taking the considerable evidence from numerous ex vivo studies on cells and tissues and from animal interventions. The review focuses predominantly on human data.

RESUMO

The feeding of colostrum and mother's transitional milk improves immune protection and neurodevelopmental outcomes. It also helps with gut maturation and decreases the risks of infection. The supply of nutrients from human milk (HM) is not adequate for preterm infants, even though preterm mother's milk contains higher concentrations of protein, sodium, zinc, and calcium than mature HM. The human milk fortifiers, particularly those with protein, calcium, and phosphate, should be used to supplement HM to meet the necessities of preterm infants. The management of fluid and electrolytes is a challenging aspect of neonatal care of preterm infants. Trace minerals such as iron, zinc, copper, iodine, manganese, molybdenum, selenium, chromium, and fluoride are considered essential for preterm infants. Vitamins such as A, D, E, and K play an important role in the prevention of morbidities, such as bronchopulmonary dysplasia, retinopathy of prematurity, and intraventricular hemorrhage. Therefore, supplementation of HM with required nutrients is recommended for all preterm infants.

RESUMO

Preterm birth is associated with a high risk of morbidity and mortality including brain damage and cerebral palsy. The development of brain injury in the preterm infant may be influenced by many factors including perinatal asphyxia, infection/inflammation, chronic hypoxia and exposure to treatments such as mechanical ventilation and corticosteroids. There are currently very limited treatment options available. In clinical trials, magnesium sulfate has been associated with a small, significant reduction in the risk of cerebral palsy and gross motor dysfunction in early childhood but no effect on the combined outcome of death or disability, and longer-term follow up to date has not shown improved neurological outcomes in school-age children. Recombinant erythropoietin has shown neuroprotective potential in preclinical studies but two large randomized trials, in extremely preterm infants, of treatment started within 24 or 48 h of birth showed no effect on the risk of severe neurodevelopmental impairment or death at 2 years of age. Preclinical studies have highlighted a number of promising neuroprotective treatments, such as therapeutic hypothermia, melatonin, human amnion epithelial cells, umbilical cord blood and vitamin D supplementation, which may be useful at reducing brain damage in preterm infants. Moreover, refinements of clinical care of preterm infants have the potential to influence later neurological outcomes, including the administration of antenatal and postnatal corticosteroids and more accurate identification and targeted treatment of seizures.

RESUMO

BACKGROUND: Oropharyngeal colostrum (OC) is a novel feeding strategy to prevent complications of prematurity. A meta-analysis was conducted to investigate whether very low birth weight infants (VLBWs) can benefit from OC. METHODS: Randomized controlled trials (RCTs) were searched from Embase, PubMed, Web of Science, and Cochrane Central Register of Controlled Trials from the date of inception until May 2019. RCTs were eligible if they used OC therapy on VLBW infants. The primary outcomes included ventilator-associated pneumonia (VAP), necrotizing enterocolitis (NEC), bronchopulmonary dysplasia (BPD), late-onset sepsis, and death. The secondary outcomes included the time of full enteral feeding and the length of stay. RESULTS: Eight RCTs involving 682 patients (OC group: 332; non-OC group: 350) were included in the meta-analysis. The results suggested that OC was associated with a significantly reduced incidence of VAP [odds ratio (OR) = 0.39, 95% confidence interval (CI): 0.17-0.88, P = 0.02] and full enteral feeding days (mean difference = -2.66, 95% CI: -4.51 to -0.80, P = 0.005), a potential significance of NEC (OR = 0.51, 95% CI: 0.26-0.99, P = 0.05), a trend toward downregulating mortality (OR = 0.60, 95% CI: 0.34-1.08, P = 0.09) and proven sepsis (OR = 0.64, 95% CI: 0.40-1.01, P = 0.06). CONCLUSIONS: OC could significantly reduce the occurrence of VAP, and consequently, its routine use should be considered for VLBWs to prevent infectious diseases. IMPACT: OC significantly reduces the occurrence of VAP and NEC in VLBW infants. OC may reduce the incidence of VAP and NEC by increasing IgA levels. Early OC therapy for mechanical ventilation of low-weight infants may prevent the occurrence of VAP.

RESUMO

INTRODUCCIÓN: La incidencia de enterocolitis necrotizante (ECN), en Chile es de 0,3 a 2,4 por mil recién nacidos vi vos, siendo principalmente afectados los neonatos prematuros, y de 8 a 12 por ciento en prematuros menores a 1.500 gramos. OBJETIVO: Describir la percepción de profesionales de salud sobre el uso de calostro en recién nacidos prematuros, como factor protector de enterocolitis necrotizante. SUJETOS Y MÉTODO: Estudio cualitativo, mediante entrevista semiestructurada a 18 profesionales de la salud en tres hospitales públicos de la región de Valparaíso. La pauta de entrevista incluyó 3 temas: Conocimientos, percepción del suministro temprano de calostro y opinión acerca de la extensión de la medida, y 6 subtemas, 2 para cada tema respectivamente: Autopercepción del nivel de conocimiento y fuentes de información; Experiencia: aspectos positivos/eventos adversos y opinión del calostro como factor protector de enterocolitis; aspectos facilitadores u obstaculizadores y opinión acerca de la medida como política nacional. Procesamiento de datos mediante análisis de contenido cualitativo, temático. RESULTADOS: El uso de calostro en prematuros se da de modo protocolizado en dos de las tres unidades de alta complejidad neonatal de la región de Valparaíso. Los participantes opinan positivamente acerca de los resultados preventivos de esta medida. Aun cuando en un tercer estable cimiento no se aplique, hay una percepción favorable acerca de su potencial beneficio y su bajo costo de implementación. Se señala, no obstante, que ésta requiere de mayor evidencia y de un protocolo de aplicación. Otras limitantes serían la insuficiente dotación y formación del personal, y la necesidad de adquirir equipamiento e insumos. CONCLUSIONES: Profesionales que han aplicado un protocolo de administración de calostro en neonatos prematuros en la Región de Valparaíso, reportan buenos resultados de salud, y promueven la motivación del equipo hacia esta praxis. Sin embargo, se considera relevante la difusión y discusión de protocolos nacionales e internacionales, así como el desarrollo de investigación local. Dadas las experiencias en curso en Chile, y el debate internacional, se considera oportuno que el tema sea abordado y discutido en la comunidad sanitaria nacional.


INTRODUCTION: In Chile, necrotizing enterocolitis (NEC) mainly affects preterm infants, with an incidence of 0.3 to 2.4 per 1,000 live births, and 8 to 12% in preterm infants weighing less than 1,500 grams. OBJECTIVE: To describe health professionals perceptions on the use of human colostrum as a preventive measu re against necrotizing enterocolitis in preterm newborns. SUBJECTS AND METHOD: Qualitative study, using 18 semi-structured individual interviews of health professionals in three public hospitals of the Valparaíso Region. The interview included 3 topics: Knowledge, Perception of early colostrum supply and Opinion about the extent of the measure, and 6 subtopics, 2 for each topic respectively: Self-perception of knowledge level and Sources of information; Experience: positive aspects/adverse events and Opinion of colostrum as a protective factor for enterocolitis; Facilitating or hindering aspects and Opinion about the measure as national policy. Data were processed through qualitative content analysis. RESULTS: Two of the three high-complexity neonatal units of the Valparaíso Re gion have a protocol for administrating colostrum in premature infants. Participants have a positive opinion about the preventive results of this measure. Even in the third hospital where there is no protocol, they have a favorable perception of its potential benefit and its low cost of implementa tion. However, we observed that this procedure requires more evidence and an application protocol. Other limitations would be the lack of staffing and training and the need for equipment and supplies. CONCLUSIONS: Professionals who have applied a colostrum administration protocol in preterm infants in the Valparaíso Region report good health outcomes and promote team motivation towards this practice. However, it is relevant to the dissemination and discussion of national and international protocols, as well as the development of local research. Given the ongoing experiences in Chile and the international debate, we considered appropriate to address and discuss the topic within the na tional health community.

RESUMO

INTRODUCTION: Preterm and small for gestational age (SGA) infants are at increased risk of poor growth, disability and delayed development. While growing up they are also at increased risk of obesity, diabetes and later heart disease. The risk of such adverse outcomes may be altered by how preterm and SGA infants are fed after birth. Faltering postnatal growth is common due to failure to achieve recommended high energy and protein intakes, and thus preterm and SGA infants are often provided with supplemental nutrition soon after birth. Enhanced nutrition has been associated with improved early growth and better cognitive development. However, limited evidence suggests that faster growth may increase the risk for later adiposity, metabolic and cardiovascular disease, and that such risks may differ between girls and boys. METHODS AND ANALYSIS: We will search Ovid MEDLINE, Embase, Cochrane CENTRAL, Cochrane Database of Systematic Reviews, controlled-trials.com, ClinicalTrials.gov and anzctr.org.au for randomised trials that studied the effects of macronutrient supplements for preterm and SGA infants on (i) developmental and metabolic and (ii) growth outcomes after hospital discharge. The outcomes will be (i) cognitive impairment and metabolic risk (co-primary) and (ii) body mass index. Individual participant data (IPD) from all available trials will be included using an intention-to-treat approach. A one-stage procedure for IPD meta-analysis (MA) will be used, accounting for clustering of participants within studies. Exploratory subgroup analyses will further investigate sources of heterogeneity, including sex and size of infants, different timing, duration and type of supplements. ETHICS AND DISSEMINATION: This IPD-MA is approved by the University of Auckland Human Participants Ethics Committee (reference number: 019874). Individual studies have approval from relevant local ethics committees. Results will be disseminated in a peer-reviewed journal and presented at international conferences. PROSPERO REGISTRATION NUMBER: CRD42017072683.

RESUMO

INTRODUCTION: In Chile, necrotizing enterocolitis (NEC) mainly affects preterm infants, with an incidence of 0.3 to 2.4 per 1,000 live births, and 8 to 12% in preterm infants weighing less than 1,500 grams. OBJECTIVE: To describe health professionals perceptions on the use of human colostrum as a preventive measu re against necrotizing enterocolitis in preterm newborns. SUBJECTS AND METHOD: Qualitative study, using 18 semi-structured individual interviews of health professionals in three public hospitals of the Valparaíso Region. The interview included 3 topics: Knowledge, Perception of early colostrum supply and Opinion about the extent of the measure, and 6 subtopics, 2 for each topic respectively: Self-perception of knowledge level and Sources of information; Experience: positive aspects/adverse events and Opinion of colostrum as a protective factor for enterocolitis; Facilitating or hindering aspects and Opinion about the measure as national policy. Data were processed through qualitative content analysis. RESULTS: Two of the three high-complexity neonatal units of the Valparaíso Re gion have a protocol for administrating colostrum in premature infants. Participants have a positive opinion about the preventive results of this measure. Even in the third hospital where there is no protocol, they have a favorable perception of its potential benefit and its low cost of implementa tion. However, we observed that this procedure requires more evidence and an application protocol. Other limitations would be the lack of staffing and training and the need for equipment and supplies. CONCLUSIONS: Professionals who have applied a colostrum administration protocol in preterm infants in the Valparaíso Region report good health outcomes and promote team motivation towards this practice. However, it is relevant to the dissemination and discussion of national and international protocols, as well as the development of local research. Given the ongoing experiences in Chile and the international debate, we considered appropriate to address and discuss the topic within the na tional health community.

RESUMO

OBJECTIVE: This study aimed to study the role of oropharyngeal administration of colostrum (OAC) in very-low-birth-weight infants for reducing necrotizing enterocolitis (NEC). STUDY DESIGN: In this randomized controlled trial, 117 infants were enrolled, 59 were randomized to OAC group and 58 to routine care group. Infants with birth weight ≤ 1,250 g and/or gestational age ≤ 30 weeks were enrolled. Infants in OAC group received maternal colostrum (0.2 mL), 0.1 mL on either side, after 24 hours of postnatal life and were given every 2 hour for the next 72 hours irrespective of the enteral feeding status of the neonate. The primary outcome of the study was the incidence of NEC (stage 2 or 3). RESULTS: Baseline characteristics were comparable between the two groups. There was no significant reduction in the incidence of NEC in OAC group (0 [0%] vs. 3 [7.1%]; p = 0.11). There was significant reduction of 7 days of hospital stay in OAC group (34.2 ± 5.7 vs. 41.5 ± 6.7 days; p = 0.04).The incidence of early-onset sepsis, late-onset sepsis, blood culture positive sepsis, and ventilator-associated pneumonia were comparable between the two groups. CONCLUSION: OAC is safe and reduces the duration of hospital stay.

RESUMO

BACKGROUND: Necrotizing enterocolitis (NEC) is a major complication confronting clinicians caring for premature infants. This investigation compares clinical outcomes before and after quality improvement-program interventions in a population of premature infants at intermediate risk for NEC. METHODS: This study is a retrospective single-center chart review of infants admitted with a birth weight of 1000-1499 g, excluding major congenital anomalies, over a 6-year period, beginning with implementation of a donor breast-milk program when mother's own milk was not available. Infants were separated into 2 epochs, before (July 2012-December 2013) and after (April 2014-June 2018) introduction of human milk-derived fortifier (Prolacta) and a daily probiotic (FloraBABY) supplement. RESULTS: Comparing 140 preintervention infants with 265 postintervention infants, NEC was significantly lower in the postintervention group: 5.2% vs 1.1% (P = 0.046). Somatic growth was similar in both epochs. CONCLUSIONS: Quality-improvement initiatives utilizing an exclusive human-milk diet and daily probiotic supplementation were associated with a decreased incidence of NEC in infants with a birth weight of 1000-1499 g. Implementation of the NEC reduction bundle did not affect infant growth.

RESUMO

BACKGROUND: An exclusive human milk-based diet has been shown to decrease necrotizing enterocolitis and improve outcomes for infants ≤1250 g birth weight. Studies have shown that infants who received an exclusive human milk diet with a donor-human milk-derived cream supplement (cream) had improved weight and length velocity when the cream was added to mother's own milk or donor-human milk when energy was <20 kcal/oz using a human milk analyzer. Our objective was to compare growth and cost outcomes of infants ≤1250 g birth weight fed with an exclusive human milk diet, with and without human milk cream, without the use of a human milk analyzer. METHODS: Two cohorts of human milk-fed premature infants were compared from birth to 34 weeks postmenstrual age. Group 1 (2010-2011) received a donor-human milk fortifier, whereas Group 2 (2015-2016) received donor-human milk fortifier plus the commercial cream supplement, if weight gain was <15 g/kg/d. RESULTS: There was no difference in growth between the 2 groups for weight (P = 0.32) or head circumference (P = 0.90). Length velocity was greater for Group 1 (P = 0.03). The mean dose of donor-human milk fortifier was lower in Group 2 (P < 0.001). Group 2 saved an average of $2318 per patient on the cost of human milk products (P < 0.01). CONCLUSIONS: Infants receiving a human milk diet with cream supplementation for growth faltering achieve appropriate growth in a cost-effective feeding strategy.
