The number of surviving children born prematurely has increased substantially during the last 2 decades. The major goal of enteral nutrient supply to these infants is to achieve growth similar to foetal growth coupled with satisfactory functional development. The accumulation of knowledge since the previous guideline on nutrition of preterm infants from the Committee on Nutrition of the European Society of Paediatric Gastroenterology and Nutrition in 1987 has made a new guideline necessary. Thus, an ad hoc expert panel was convened by the Committee on Nutrition of the European Society of Paediatric Gastroenterology, Hepatology, and Nutrition in 2007 to make appropriate recommendations. The present guideline, of which the major recommendations are summarised here (for the full report, see http://links.lww.com/A1480), is consistent with, but not identical to, recent guidelines from the Life Sciences Research Office of the American Society for Nutritional Sciences published in 2002 and recommendations from the handbook Nutrition of the Preterm Infant. Scientific Basis and Practical Guidelines, 2nd ed, edited by Tsang et al, and published in 2005. The preferred food for premature infants is fortified human milk from the infant's own mother, or, alternatively, formula designed for premature infants. This guideline aims to provide proposed advisable ranges for nutrient intakes for stable-growing preterm infants up to a weight of approximately 1800 g, because most data are available for these infants. These recommendations are based on a considered review of available scientific reports on the subject, and on expert consensus for which the available scientific data are considered inadequate.

This paper reviews current knowledge on the role of the long-chain polyunsaturated fatty acids (LC-PUFA), docosahexaenoic acid (DHA, C22:6n-3) and arachidonic acid (AA,, in maternal and term infant nutrition as well as infant development. Consensus recommendations and practice guidelines for health-care providers supported by the World Association of Perinatal Medicine, the Early Nutrition Academy, and the Child Health Foundation are provided. The fetus and neonate should receive LC-PUFA in amounts sufficient to support optimal visual and cognitive development. Moreover, the consumption of oils rich in n-3 LC-PUFA during pregnancy reduces the risk for early premature birth. Pregnant and lactating women should aim to achieve an average daily intake of at least 200 mg DHA. For healthy term infants, we recommend and fully endorse breastfeeding, which supplies preformed LC-PUFA, as the preferred method of feeding. When breastfeeding is not possible, we recommend use of an infant formula providing DHA at levels between 0.2 and 0.5 weight percent of total fat, and with the minimum amount of AA equivalent to the contents of DHA. Dietary LC-PUFA supply should continue after the first six months of life, but currently there is not sufficient information for quantitative recommendations.

In order to assess the potential fo procalcitonin measurement in the management of neonatal sepsis, daily variations in serum procalcitonin (measured by an immunoluminometric assay) were evaluated in 94 control and infected newborn infants in comparison to C-reactive protein (measured by an immunonephelometric method). High levels of procalcitonin correlated with bacterial invasion and showed no discrepancies with C-reactive protein. procalcitonin increased (up to 400 micrograms l-1 and returned to the normal range (< 0.1 microgram l-1) more quickly than C-reactive protein, suggesting that procalcitonin may be an early marker of favourable outcome. Another finding is a significant procalcitonin peak on the first day of life in the control group, independent of any infectious stimulus. In conclusion, procalcitonin seems to be an interesting marker of neonatal sepsis but additional investigations are needed to understand better its mechanism of synthesis in order to determine its clinical usefulness.

A single-center prospective cohort study was designed to identify alterations of renal function during childhood in children born prematurely. A cohort of 143 such babies born over a 4-year period (birth weight less than 1000 g and/or less than 30 weeks of gestation) was prospectively included at birth. A mailing was sent to all parents to propose renal evaluation. Among the 50 included children, 23 had intra-uterine and 16 had extrauterine growth retardation. When comparing both of these groups to 11 children with appropriate pre- and postnatal growth at a mean follow-up of 7.6 years, both groups of growth-restricted children had slightly but significantly lower glomerular filtration rates, measured by inulin clearance, although both groups were still within the normal range for their ages. There were no differences for other renal parameters, neonatal therapies or complications, except for postnatal corticosteroid exposure. Children with extrauterine growth restriction were found to have significantly lower protein-energy intake during their first week of life than the intrauterine growth-restricted or the normotrophic children. Our study found that children with either intra- or extrauterine growth retardation are at risk of decreased glomerular filtration rates during childhood. Extrauterine growth restriction represents a new risk factor for long-term renal impairment in premature children.
