Necrotizing enterocolitis - classification and two initial steps towards prevention.
The premature infant suffers from immaturity of all organ systems , one of them being the gastrointestinal tract . When the infant is born , the immature gastrointestinal tract is exposed to milk and simultaneously colonized by high densities of bacteria . The combination of milk , microbiota and an immature gut , leaves the infant vulnerable to developing the dreaded intestinal emergency necrotizing enterocolitis ( NEC ) . NEC is often very aggressive and no cure exists , which means that prevention is an utmost important topic to research ers , physicians , parents - and infants . Despite immense research during the last decades , no specific test to determine if an infant suffers from NEC exists . Most neonatal units use Bell 's staging criteria , which are based on clinical and radiographic findings , as a diagnostic tool ; however the diagnosis given according to Bell 's stages has not been vali date d. In study I , we aim ed to determine the validity of the NEC diagnosis given at discharge . An expert panel consisting of a neonatologist , a paediatric surgeon and a paediatric radiologist served as the golden st and ard . We found that the diagnosis given at discharge had a poor validity which significantly affected the reported incidence of NEC in the neonatal department at Rigshospitalet , Denmark . The validity of the NEC diagnosis was worse than the validity of most other paediatric diagnoses that had been investigated . In studies II and III , we aim ed to explore possible means of NEC prevention . The role of nutrition in NEC development is well established with mother 's milk as the best option to avoid NEC in the preterm infant . Maternal milk is , however , most often not available in sufficient amounts during the first days of life , and preterm infant formula or human donor milk is used in its absence . Studies in preterm piglets showed that bovine colostrum equally to human donor milk protected against NEC compared to infant formula . Furthermore , bovine colostrum was superior to human donor milk in stimulating gut immunity and digestive functions . Hence , in study II we aim ed to design a pilot study of bovine colostrum used as a supplement to maternal milk in the first days of life and to determine if the study was feasible . In the paper , we present the protocol and the results of the first two phases of the Precolos study in which 12 infants were included and received pasteurized , spray-dried and reconstituted bovine colostrum during the first days of life as the first infants in the world . We found that the infants tolerated bovine colostrum without clinical adverse effects , but we also observed a transient hypertyrosinemia on day seven of life in five infants . The results were evaluated by a safety management board which encouraged us to continue the pilot study with the last phase , which was a r and omized controlled trial of 20 + 20 infants comparing supplementation with bovine colostrum to supplementation with st and ard nutrition . The r and omized trial has just finished recruitment . At last , we wanted to shed light on a possible microbiological angle of NEC prevention . Dysbiosis and bacterial translocation are believed to play a crucial role in the development of NEC as intestinal pneumatosis , which occurs when bacteria produce gas inside the intestinal wall , is a pathognomonic radiographic finding . In a quality improvement study from the US published in 2014 , NEC incidence was significantly reduced after the implementation of several quality improvement interventions . St and ardized weekly exchange of nasogastric feeding tubes was suggested as one of the potential NEC-reducing interventions . In the neonatal unit at Rigshospitalet , Denmark , preterm infants are fed 8 - 12 times daily through a resident nasogastric feeding tube which is exposed to body temperature , contains milk residuals from the last meal and is h and led by both parents and personnel . Since bacterial pollution of milk given through the nasogastric feeding tube might be NEC-inducing , we aim ed in study III to determine the bacterial load given to the infants when feeding them through a tube . We collected 92 used nasogastric feeding tubes and flushed them with one ml saline each to imitate a meal given through them . Eighty-nine percent of the tubes contaminated the meals with more than 1000 colony-forming units of bacteria and fifty-five percent contaminated the meals with the possible pathogens Enterobacteriaceae or Staphylococcus aureus . The concentration of bacteria in the saline flushed through the tubes was as high as 109 colony-forming units per ml ; however , neither the risk of contamination nor the concentration of bacteria in the flush was associated with the duration of use . Implementation of st and ardized weekly exchange of feeding tubes would therefore not prevent the contamination of meals . In conclusion , the studies included in this thesis serve as a base for future studies investigating the prevention of NEC . We found a poor validity of the NEC diagnosis given at discharge . This should be kept in mind when conducting epidemiological studies of NEC and especially when conducting interventional trials with NEC as an outcome . If the findings of the r and omized part of the Precolos study indicate a positive effect of bovine colostrum and do not give rise to concerns regarding feasibility , safety or tolerability , a large-scale r and omized controlled study with NEC as the primary outcome will be planned . Based on the high concentrations of bacteria found in the nasogastric feeding tubes , a r and omized controlled trial investigating whether the frequency of feeding tube exchange affects the early colonization has been commenced in the neonatal department at Rigshospitalet . Hopefully , the results of these studies will bring us closer to preventing NEC in the future
