Abstract

Human milk is the gold standard to provide nutritional support for all healthy and sick newborn infants including the very low birth weight (VLBW) infant (<1500 g). It has both nutritional and anti-infective properties which are especially important for these infants at risk for sepsis and necrotizing enterocolitis. Human milk alone is insufficient to meet the nutritional needs for VLBW infants, especially protein and minerals. There is a conundrum between achieving the nutritional, immunologic, developmental, psychological, social, and economic benefit with human milk vs. the inadequate growth with unfortified human milk for VLBW leading to nutritional inadequacy, growth failure and poor neurodevelopmental outcome. The use of multicomponent fortifiers to increase calories and provide additional protein, vitamins, and minerals has been associated with short-term benefits in growth. Most current fortifiers are derived from cow’s milk, however there are concerns regarding a possible association between the use of cow’s milk-based fortifier and NEC. There is also an exclusive human milk diet with a fortifier derived solely from human milk. There are three approaches for fortifying human milk and include fixed dosage or “blind fortification”, adjustable fortification using the blood urea nitrogen as a surrogate for protein nutriture to modify dosage of fortification, and targeted, individualized fortification that is based on periodic human milk analysis.
