Evidence suggests hundreds of babies develop a serious bowel problem called necrotising enterocolitis (NEC) each year in the UK.1-6 Babies with NEC need urgent treatment, often involving emergency surgery. Sadly, many babies with NEC lose their lives and some of those who survive suffer long-term complications, such as persistent bowel problems, poor growth and learning difficulties.7 Researchers at the Universities of Oxford and Southampton, led by Associate Professor Ed Juszczak, are investigating how different milk feeds and food supplements affect babies’ chances of developing NEC, in the hope of better understanding why so many babies still develop this devastating condition.
How are babies’ lives affected now?
Up to one in 20 babies in neonatal units develops NEC.4 Premature babies, those with a very low birth weight and babies who are already poorly are the most susceptible to this life-threatening condition.
NEC happens when the lining of a baby’s intestines becomes inflamed and starts to die. The exact cause of this is unknown.
“Babies with NEC usually become extremely unwell and need urgent treatment,” says Mr Nigel Hall. “Babies often need emergency surgery to remove damaged parts of the bowel.”
NEC is in fact the most common reason for emergency surgery in newborn babies.8 Babies who survive surgery often have to stay in hospital for a long time afterwards. Consequences of NEC during childhood include problems with nutrition and growth, learning difficulties, and problems with hearing, vision and movement.
“Sadly, NEC remains a significant cause of death and suffering in premature babies,” says Professor Juszczak. “A better understanding of this devastating condition is needed urgently.”
How could this research help?
The researchers are investigating whether the way babies are fed affects their chances of developing NEC.
“Babies who are at high-risk of developing NEC tend to be given breast milk first, because evidence suggests breast milk is protective against the condition,” says Mr Hall. “However, breast milk doesn’t always provide all the nutrients that very premature babies need to grow healthily, so breast milk is often fortified with extra protein, vitamins and minerals, or babies are given formula.”
The team is investigating whether babies’ chances of developing NEC increase if breast milk is fortified, or if they’re given formula milk, or if the type of milk they’re being given is changed.
The ultimate goal is to find out whether changes in feeding practices could reduce babies’ chances of developing NEC, so protecting them from suffering and saving their lives.
