Abstract: The optimal diet for the low birthweight infant is one that supports a growth rate approximating that of the third trimester of intra-uterine life without imposing stress on the developing metabolic or excretory systems. Although preterm human milk does not meet the energy and nutrient needs of developing preterm infants, the benefits such as contributions to host defence and gastrointestinal trophic aspects, and the psychological benefits of maternal-infant bonding, make it the preferred diet. 相似文献

AIM: To evaluate the rate and clinical expression of postnatal cytomegalovirus (CMV) infection transmitted through breast milk in extremely preterm infants. METHODS: Ten extremely preterm infants and their six mothers were included. Maternal CMV serology was determined. Breast milk samples and urine samples from the infants were screened for CMV. Symptoms and laboratory findings of CMV infected infants were documented. All infants received partly fresh and/or defrosted breast milk. RESULTS: CMV-DNA was found in breast milk in four of five CMV-seropositive mothers. Two infants were infected by CMV. They were the only infants fed with breast milk positive for viral culture. One infant developed hepatic affection concurrent with viral excretion in urine. This infant was later diagnosed with cystic fibrosis. CONCLUSION: This study supports that CMV transmission through breast milk can aggravate the clinical course in extremely preterm infants with preexisting hepatic conditions. 相似文献

AIM: Various mechanisms of innate immunity and gastrointestinal integrity are potentially affected by soluble Fas (sFas) and sFas ligand (sFasL). Assuming that sFas and sFasL in milk reflect cellular events during lactogenesis, we aimed to assess the impact of premature parturition and duration of lactation on the concentrations of sFas and sFasL in human milk. PATIENTS AND METHODS: The content of the soluble form of the cell surface receptor Fas (sFas) and its natural ligand (sFasL) was measured in human breast milk of 44 healthy mothers after preterm (<35 wk, n=21) and term (>37 wk, n=23) delivery. Milk was furthermore classified as immature breast milk (days 4-7 of lactation) or mature breast milk (days 35-45 of lactation). Breast milk (2-3 ml) was sampled 5 min after the start of breastfeeding by manual expression or milk pump, and stored at -20 degrees C until analysis by an ELISA. RESULTS: sFas and sFasL concentrations were lower in immature milk after preterm compared to term delivery (sFas: 1.71; 1.38-2.47 ng/ml vs 3.03; 2.02-4.30 ng/ml, p < 0.001; sFasL: 0.13; 0.07-0.21 ng/ml vs 0.29; 0.15-0.60 ng/ml, p < 0.001 [median +/- interquartile range]). Mature milk samples, taken 1 mo later from both gestational groups, did not differ in sFas/sFasL content. Soluble Fas was positively correlated with sFasL in the same sample of immature (p < 0.001) and mature human milk (p < 0.05). A positive correlation was found between sFas and sFasL in immature and mature milk samples of the same mother (p < 0.01). The body mass index of the mothers and duration of pregnancy were positively correlated with the sFas and sFasL content in immature milk (p < 0.05 and p < 0.01, respectively) but not in mature milk. CONCLUSION: Preterm newborn infants fed with breast milk have a lower intake of sFas and sFasL compared to term neonates. Our results demonstrate that preterm delivery affects breast milk composition. 相似文献

Although the unique composition of preterm milk (PTM) has led to its increasing use in feeding of low birthweight (LBW) infants, controversy exists as to whether such milk adequately meets their requirements. This study compares the clinical tolerance and anthropometric, biochemical and haematological parameters of LBW infants fed exclusively with their own mother's PTM, a premature infant formula (Alprem; Nestlé Australia) and a mixture of PTM and Alprem. Of 90 enrolled LBW infants (1000-1750 g birthweight), 78 completed the feeding trial for a mean duration of 42 days. Twenty-eight babies were fed Alprem (Group A), 31 received a mixture of Alprem and PTM (Group B) and 18 received PTM (Group C). Babies in Groups A and B were smaller, less mature and more asphyxiated at birth than those in Group C. Weight gain from full enteral feeding was greater in Group A (18.1 g/kg per day) and Group B (17.6 g/kg per day) than in Group C (13.0 g/kg per day). Throughout the trial, weight gain in Groups A and B exceeded predicted intra-uterine growth rates, whereas that for Group C approximated the predicted intra-uterine growth rates. Growth rates of length and head circumference were also greatest in the Alprem-fed babies. Infants receiving PTM were supplemented with calcium, sodium, vitamins and energy, whereas the only three infants requiring mineral supplementation in the Alprem group were those receiving Frusemide therapy for chronic lung disease. Lower serum concentrations of phosphorus, iron, albumin and urea, and higher zinc and alkaline phosphatase concentrations were found in infants receiving PTM (P<0.05). Overall both PTM and Alprem were well tolerated with the four cases of necrotizing enterocolitis and five cases of transient gastrointestinal intolerance distributed equally among the groups. Alprem is a satisfactory alternative to PTM for the feeding of LBW infants as it provides adequate nutrition and supports a growth rate in excess of that in utero without stressing the infant's metabolic or excretory systems. 相似文献

目的通过回顾性队列研究评价早产儿母乳喂养强化时机对早产儿住院期间生长的影响,探讨早产儿母乳喂养强化的最佳时机和进程。方法选择2009年11月至2011年3月在4家三甲医院新生儿重症监护病房住院治疗、住院期间母乳喂养量大于总喂养量50%并应用母乳强化剂的早产儿为研究对象。根据开始添加母乳强化剂的时间分为早强化组[奶量〈90ml/(kg·d)即开始强化]和晚强化纽[奶量≥90ml/(kg·d)开始强化],再根据从开始添加母乳强化剂至足量强化的时间分为快强化组(1~3天完成足量强化)和慢强化组(≥4天完成足量强化)。对不同组间早产儿的合并症、肠内营养情况及生长情况进行比较。结果符合入选标准的早产儿共67例。早强化组32例,晚强化组35例,两组基本情况、坏死性小肠结肠炎(NEC)等合并症发生率、住院期间体重增长速率差异均无统计学意义(P〉0.05)。早强化组出院时小于胎龄儿(SGA)比例与出生时比较差异无统计学意义(P〉0.05),晚强化组出院时SGA比例较出生时增多(72.7%比42.9%,P=0.013)。快强化组41例,慢强化组26例,两组基本情况、NEC等合并症发生率差异无统计学意义(P〉0.05)。快强化组住院时间更短[(34.0±15.6)天比(43.0-4-13.6)天,P=0.02],住院期间体重增长速率更快[(18.3±5.3)g/(kg·d)vs(15.7±3.7)g/(kg·d),P=0.03]。快强化组出院时SGA比例与出生时比较差异无统计学意义(P〉0.05),慢强化组出院时SGA比例较出生时更多(65.4%比30.8%,P=0.012)。结论早产儿母乳喂养晚强化或慢强化均加剧宫外生长迟缓,早强化或快强化对早产儿是安全的。建议在早产儿母乳喂养量达90ml/(kg·d)之前开始添加母乳强化剂;足量强化应尽量在3天内完成。 相似文献

Human milk is often inadequate nutritionally for preterm infants. We investigated the effect of adding a commercially prepared milk fortifier to human (maternal or bank) milk and measured changes in lower leg length velocity (LLLvel) using knemometry, weight gain and biochemical indices of nutrition. Babies were allocated to one of three feed groups, in a semi-randomized fashion, to receive human milk alone (group I), fortified human milk (group II) or a preterm formula (group III). The birthweights (median and R) and birth gestations (median and R) of the three groups were as follows: group I 1099 g (654-1248 g) and 28 wk (26-32 wk); group II 838 g (742-1340g) and 31 wk (28-36); group III 1136g (624-1552g) and 32 wk (27-36 wk). All babies who received fortified milk either showed significant (p = 0.0004) acceleration in LLLvel during the period studied, or maintained their pre-study period velocity. This increase in LLLvel was comparable to that achieved by a group of babies given a standard preterm infant formula (p < 0.001). By comparison, the control group's change in LLLvel was more modest (p = 0.04). Babies who received human milk with the fortifier added had the lowest serum levels of alkaline phosphatase at the end of the study period when compared to the other two groups. Other biochemical indices were similar in the three feed groups. No adverse clinical events were encountered which could be attributed to the use of the breast milk fortifier. 相似文献

BACKGROUND: Early diagnosis and treatment of homocystinuria with methionine-free or low methionine formulae significantly improve prognosis in children found by newborn screening and treated soon after birth. Betaine (Bet) supplementation is also an effective strategy for dietary treatment of homocystinuria. However, previous reports on diet therapy have only examined methionine and cysteine concentrations but not those of Bet and homocysteine (Hcy) in infant diets. METHODS: We measured Bet and Hcy concentrations in three methionine-free formulae, five infant starter formulae, and 33 samples of human breast milk from 10 mothers. RESULTS: In methionine-free formulae, Hcy but not Bet was isolated. However, in human breast milk and infant starter formulae, both Bet and Hcy were detected. However, the Bet concentration was not sufficient for the treatment. CONCLUSIONS: Our study suggests that methionine-free formulae should have Hcy eliminated and be fortified with Bet to the concentration of 150 mg/dL for the treatment of homocystinuria. 相似文献

Failure of adequate gastric emptying frequently prevents successful, early enteral nutrition in the preterm infant. The effect on gastric emptying of adding breast milk fortifier is unknown, but clinical experience suggests that it is less well tolerated by some infants. We therefore compared gastric-emptying rates of breast milk and fortified breast milk within pre-term infants, using a previously described ultrasonic technique. Eleven infants were studied on 22 occasions. Median (range) gestation of the group was 28 weeks (25-31) with birth weight 1090 g (714-1360). The human milk fortifier FM-85 (Nestlé, Vevey, Switzerland) was used in all infants. Half-emptying time for unfortified breast milk was less than half that for fortified breast milk. Mean (±SEM) half emptying times were 21 min (±3.6) and 48 min (±4.0), respectively. Breast milk emptied faster than fortified breast milk in 10 out of 11 patients. These data demonstrate that the addition of human milk fortifier can significantly slow gastric emptying. This has important implications for the management of infants who have feed intolerance. 相似文献

The study was designed to compare two different human milk fortifiers in a group of very low birth weight (VLBW) infants by analysing nitrogen and fat balances, serum concentrations of alpha-amino-nitrogen, urea, and prealbumin as well as growth rates when human milk enriched with one of the two studied fortifiers was fed to the infants. Fortifier A contained different bovine proteins, peptides and amino acids and had an amino acid composition comparable to that of the nutritional available proteins in human milk, with carbohydrates, and minerals. Fortifier B was composed of freeze-dried skimmed human milk and minerals to achieve a similar macronutrient composition in both fortifiers.Eleven infants were fed with human milk enriched with fortifier A and 13 with fortifier B. After a 10-day equilibration period, a 3-day metabolic balance was performed. On the 14th day of the study blood was obtained preprandially for serum analysis and growth rates were estimated. The nitrogen absorption rate (93.8% vs 93.5%) as well as the retention rate (80.8% vs 78.5%) were no different between the groups. The fat absorption rate (92.3% vs 91.5%) as well as the weight gain (32.1 vs 31.1 g/day) were similar and there were no differences in the serum parameters studied. The results indicate that feeding VLBW infants with human milk enriched with a well-balanced bovine fortifier fulfil their nutritional requirements as well as diets composed exclusively of human milk protein. 相似文献

Freezing human milk is recommended to inactivate cytomegalovirus (CMV). A case of a preterm infant exclusively receiving frozen breast milk from his CMV seropositive mother showed that storage of breast milk for two months at -20 degrees C did not prevent symptomatic postnatal CMV infection. 相似文献

The metabolic changes that occur during the postnatal weaning period appear to be particularly important for future health, and human breast milk is considered to provide the optimal source of nutrition for infants. Our previous studies examined the effect of feeding type on antioxidative properties, glucose and insulin metabolism, the lipid profile, metabolomics, and prostaglandin (PG) metabolism in term and preterm infants. A urinary marker of oxidative DNA damage (8‐hydroxy‐2′‐deoxyguanosine) was significantly lower in breast‐fed term and preterm infants than in formula‐fed infants. Markers of insulin sensitivity were significantly lower and atherosclerotic indices were significantly higher in breast‐fed preterm infants than in mixed‐fed infants at discharge. On urinary metabolomics analysis, choline, choline metabolites, and lactic acid were significantly lower in breast‐fed term infants than in formula‐fed infants. Urinary PGD2 metabolite level in breast‐fed term infants was also significantly lower than in formula‐fed term infants. This indicates that human breast milk affects biological metabolism in early infancy. 相似文献

ObjectiveTo compare bacterial growth in pure colostrum versus colostrum with human milk fortifier (HMF) containing iron.MethodsThe growth of Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa in 78 samples of pure colostrum or colostrum with added iron-containing HMF was compared. For qualitative analysis, filter paper discs were immersed in samples from each group and incubated for 48 hours with 101 colony forming units (CFUs)/mL of each strain. For quantitative assessment, 1 mL of each strain containing 107 CFUs/mL was homogenized with 1 mL of either colostrum or colostrum with human milk fortifier, seeded into a Petri dish, and incubated at 37 °C. Twenty-four hours later, the number of CFUs was counted.ResultsThe qualitative analysis showed no difference in bacterial growth. In the quantitative evaluation, E. coli growth in the control group was 29.4 ± 9.7 × 106 CFU/mL, while in the HMF group it was 31.2 ± 10.8 × 106 CFU/mL. The difference between the average growth was 1.9 ± 4.9 × 106 CFU/mL (p = 0.001). There were no differences in S. aureus and P. aeruginosa growth.ConclusionAddition of iron at this concentration reduces breast milk bacteriostatic action against E. coli. 相似文献

"Drip breast milk" is that milk which spontaneously drips from the contralateral breask during the suckling of an infant. Biochemically and immunologically, pooled drip milk resembled pooled mature expressed breast milk, although it has a lower fat concentration. About 15% of lactating women are capable of producing drip milk; volumes produced are up to 188 ml/donor/day. A milk bank is described which processes 1400 liters of drip milk/yr. Heat treatment of this milk with a semi-automated holder pasteurizer caused a 21% reduction in IgA concentration and a 36% reduction in lysozyme activity, as well as a decrease in the ability of the milk to inhibit the growth of E. coli. In comparison with boiling, pasteurization was as effective in reducing total bacterial content provided the milk initially contained fewer than 10(6) bacteria/ml. 相似文献

采集母乳与母乳库母乳喂养对早产儿生长发育的影响 总被引:2,自引:0,他引:2
采集母乳与母乳库母乳可以作为早产儿在无法获得直接母乳喂养时可选择的一种喂养方式.目前文献提示,单纯以采集母乳与母乳库母乳喂养的早产儿生后短期内生长要慢于早产儿配方乳喂养,对早产儿远期生长的影响尚不明确;但采集母乳与母乳库母乳喂养可供给早产儿一定量的人乳特有成分,有利于早产儿神经发育,并减少坏死性小肠结肠炎、喂养不耐受等喂养相关并发症的发生.采集母乳与母乳库母乳的临床广泛应用还面临一些亟待解决的问题,将来的研究应更多关注于对早产儿远期生长发育的影响. 相似文献
