“…However, there arc reports that milk of mothers who delivered premature infants has a greater protein concentration that satisfies the infant's needs (Pamblanco et al 22 , 1986, Lemons et al 19 , 1986), though no conclusive data are available for TSGA infants.…”

“…The composition of breast milk from mothers of TSGA infants has been investigated in only a few studies (Garza et al 13 , 1981; Barros et al 4 , 1984; Pamblanco et al 22 , 1986; Grumach et al 16 , 1993) and the present study was undertaken to evaluate the composition of breast milk from mothers of small for gestational age infants delivered at term and to compare it to that of milk from mothers of premature infants and adequate for gestational age term infants. These groups of samples were collected until the 60th day of lactation, so the nutritional factors in the same mother could be studied longitudinally.…”

CRUMACH, A.S. et al. Nutritional factors in milk from Brazilian mothers delivering small for gestacional age neonates. Rev. Saúde Pública, 27: 455-62, 1993. The composition of breast milk from brazilian mothers delivering low birthweight infants and its adequacy as a source of nutrients for this group has not yet been fully elucidated. A total of 209 milk samples from 66 women were analysed. The mothers were divided into three groups: G1, mothers delivering term babies of low birthweight (TSGA, n=16); G2, mothers delivering preterm babies of appropriate birthweight (PTAGA, n=20); G3, mothers delivering term babies of appropriate birthweight (TAGA, n=30). The following factors were analysed: osmolarity, total proteins and protein fractions, creamatocrit, sodium, potassium, calcium and magnesium. Milk samples were collected 48 h and 7, 15, 30 and 60 days after delivery. The groups did not differ significantly in terms of osmolarity, total proteins and fractions, creamatocrit, calcium, magnesium or potassium throughout the study period. Sodium levels were higher in all samples from mothers of TSGA infants and in samples from mothers of PTAGA infants on the 7th, 15th and 30th days than in milk from the TAGA group. The authors consider the needs of the low birthweight and TAGA infants and that these high sodium levels may be necessary for growth of low birthweight infants.

“…Other studies also showed a decrease in LF concentration with more days postpartum, including Lnnerdal et al 1976b; Goldman et al 1982b; Prentice et al 1983; Butte et al 1984; Houghton et al 1985; Lewis-Jones et al 1985b; Pamblanco et al 1986; Sanchez-Pozo et al 1986; Montgomery et al 1987; Filteau et al 1999; Velona et al 1999; Ronayne de Ferrer et al 2000; Montagne et al 2001; Mehta and Petrova 2011; Yuen et al 2012; Molinari et al 2013; Broadhurst et al 2015; Trend et al 2015. …”

Lactoferrin (LF) is a breast milk glycoprotein with antimicrobial and anti-inflammatory effects. Its beneficial properties in infants, especially in those born preterm, are currently being studied in clinical trials. However, the maternal and nursing infant factors that may affect the concentration of LF in breast milk are still not clear. We conducted a systematic review to investigate the factors that may affect LF concentration. We used a 2-step approach to identify the eligible studies according to inclusion/exclusion criteria and to determine which studies would be considered. We included 70 qualified articles from 29 countries with publication dates ranging from 1976 to 2015. We described the correlation between LF concentration in breast milk and lactation stage; 10 maternal factors, such as race, parity, among others; and 2 infant factors, infections and prematurity. Colostrum has the highest LF levels, but they decrease with days postpartum. No other factor has been consistently associated with LF concentration. A major limitation of the majority of the published studies is the small sample size and the different methods used to measure LF concentration. Therefore, there is a need for large, multicenter studies with standardized study design, sample collection, and LF measurement methods to identify clinically significant factors associated with LF expression in breast milk, which will help promote exclusive breastfeeding in preterm infants.

“…Both low-birth-weight groups, preterm and term small-for-date, showed similar patterns in relation to IgA concentration and other protective factors. Pamblanco et al [24] studying equivalent groups in Spain also found high IgA levels in colostrum from small-fordate babies' mothers. Higher levels of IgA in preterm than in full-term colostrum were also described by Dawarkadas et al [11], who showed that although the mean volume of colostrum is significantly lower in preterm than in full-term colostrum, the concentrations of total protein, sIgA, lysozyme, and lactoferrin were significantly higher in preterm colostrum.…”
