Study Overview
Brief Summary
Feeding preterm infants is of great challenge in the NICUs. Mother's own milk is considered as the best for the digestive system followed by donor milk. Preterm infant formula is related to more feeding problems and other gut complications in these babies, such as necrotizing enterocolitis. Bovine colostrum contains higher amounts of protein, growth factors and immuno-regulatory components (e.g. immunoglobulins), which has been used in many other situations to promote health. The investigators plan to give bovine colostrum to preterm infants with birth weights between 1000 and 1800 g, or born between 27+0 and 32+6 weeks of gestational age, in order to promote feeding and intestinal health in these babies. This current study is a feasibility pilot study and the investigators hypothesized that supplementing BC to MM (if available) is safe and tolerable when used within the first 10-14 days of life in preterm infants.
Detailed Description
Preterm birth (<37 weeks gestation) occurs in 10% of all pregnancies worldwide and the optimal way to feed a newborn preterm infant, when breast-feeding is impossible, is not clear. Excessive enteral feeding predisposes to various complications and necrotizing enterocolitis (NEC) that occur in 7% of preterm infants born with less than 1500 g body weight. Early feeding with small volumes of milk is applied to promote GIT maturation and add some nutrients and energy. It is assumed that early feeding allows more rapid advancement to full enteral feeding (EN, e.g 120-160 ml/kg/d) and weaning from parenteral nutrition (PN). This is important to reduce PN-related complications (e.g. sepsis) and to better stimulate body and organ (e.g. gut, brain) development. However, it remains unclear what is the best milk diet when mother's own milk (MM) is not available. Infant formula (IF) and banked human donor milk (DM) are the most frequently used alternatives to MM. MM is superior to IF in promoting feeding tolerance, intestinal function, and NEC resistance in preterm infants. Feeding with DM is also believed to be beneficial, relative to IF, although this pasteurized milk obtained from mothers later in lactation may be less beneficial, relative to the first milk, colostrum. There are differences in the amount and composition between human colostrum and bovine colostrum (BC), but relative to mature human milk, BC contains higher amounts of protein, growth factors and immuno-regulatory components (e.g. immunoglobulins). Large amount of protein in BC provides higher enteral protein intake and may enable a reduction in the use of PN and central venous catheters, and hereby reduced risk of infection. Also this may lead to reduced weight loss and improved growth of the brain and the body. In addition, maturational and NEC-protective effects of BC have repeatedly been documented in preterm pigs when BC is used as the first diet after birth. The investigators therefore plan to investigate whether using BC as nutrition for preterm infants in the first weeks of life is safe, tolerable, and helps to provide nutrients and gut maturation , when MM is not in sufficient amounts or not available.

- •Congenital infection

Arms & Interventions
Control group
Infants are fed according to the standard feeding practices at each hospital. At FWCH & SBMCH babies are fed infant formula supplemented to mother's own milk (if avaible), and at RH, babies are fed donor milk supplemented to Mother'w own milk (if avaible).
Colostrum group
Infants are fed bovine colostrum supplemented to mother's own milk (if avaible) for max. 10 days at RH and 14 days at FWCH & SBMCH.
Intervention: Bovine colostrum (Dietary Supplement)
Outcomes
Primary Outcomes
The primary outcome is the tolerability of bovine colostrum feeding
Time Frame: From birth until the recruited subject reaches postmenstrual age at 37 weeks or discharge home, whichever comes first
The main purpose of this feasibility pilot study is to investigate whether preterm infants can tolerate bovine colostrum as their first nutrition supplemented to mother's own milk (if available). Presence of feeding intolerance is defined as at any time when feeding is withheld by the neonatologists from day 1-7 and from day 8-14.
Secondary Outcomes
- Days to regain birth weight(From birth until the recruited subject reaches postmenstrual age at 37 weeks or discharge home, whichever comes first)
- Combined incidence of serious infections and NEC(From birth until the recruited subject reaches postmenstrual age at 37 weeks or discharge home, whichever comes first)
- Plasma citrulline level(On day 7±1 at RH & HH and on day 7±1 and 14±1 at FWCH & SBMCH)
- Lactase activity and intestinal permeability(On day 7±1)
- Anthropometry data(Weekly measured from birth until the recruited subject reaches postmenstrual age at 37 weeks or discharge home, whichever comes first)
- Time to full enteral feeding(From birth until the recruited subject reaches postmenstrual age at 37 weeks or discharge home, whichever comes first)
- Days on parenteral nutrition(From birth until the recruited subject reaches postmenstrual age at 37 weeks or discharge home, whichever comes first)
