Oropharyngeal administration of colostrum targeting gut microbiota and metabolites in very preterm infants: protocol for a multicenter randomized controlled trial. BMC Pediatr 2023; 23:508. [PMID: 37845612 PMCID: PMC10577906 DOI: 10.1186/s12887-023-04346-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/12/2022] [Accepted: 10/03/2023] [Indexed: 10/18/2023] Open
Abstract
BACKGROUND Oropharyngeal administration of colostrum (OAC) has an immune-stimulating effect on oropharyngeal-associated lymphoid tissue, and can promote the maturation of the gastrointestinal tract. However, how OAC promotes intestinal maturation in preterm infants by altering gut microbiota remains unclear. We aim to assess changes in gut microbiota and metabolites after OAC in very preterm infants. METHODS A multicenter, double-blind, randomized controlled trial will be conducted in three large neonatal intensive care units in Shenzhen, China, with preterm infants with gestational age less than 32 weeks at birth and birth weight less than 1500 g. It is estimated that 320 preterm infants will be enrolled in this study within one year. The intervention group will receive oropharyngeal administration of 0.2 ml colostrum every 3 h, starting between the first 48 to 72 h and continued for 5 consecutive days. Following a similar administration scheme, the control group will receive oropharyngeal administration of sterile water. Stool samples will be collected at the first defecation, as well as on the 7th, 14th, 21st and 28th days after birth for analysis of effect of OAC on gut microbiota and metabolites through 16sRNA gene sequencing and liquid chromatography-mass spectrometry. DISCUSSION This proposal advocates for the promotion of OAC as a safe and relatively beneficial protocol in neonatal intensive care units, which may contribute to the establishment of a dominant intestinal flora. Findings of this study may help improve the health outcomes of preterm infants by establishment of targeted gut microbiota in future studies.

Abstract
Colostrum from mothers is rich in immunomodulating bio-factors such as immunoglobulins (IgA), lactoferrin, and oligosaccharides and supports gut microbial and inflammatory processes. The support in these processes may provide some relief for infants who are born pre-term. Pre-term infants are more likely to develop necrotizing enterocolitis (NEC), late-onset sepsis (LOS), and ventilator-acquired/associated pneumonia (VAP). Due to the components of colostrum, there may be incentives towards early administration for preterm infants. An extensive literature review was done using ProQuest, ScienceDirect, and PubMed. Only meta-analyses and experimental studies were used. The search included the keywords 'colostrum and preterm' and 'colostrum and necrotizing enterocolitis'. The initial search generated 13,543 articles and was narrowed to 25 articles through comprehensive inclusion and exclusion criteria. There were significantly higher levels of Lactobacillus and Bifidobacterium in pre-term infants given colostrum and a decrease in Moraxellaceae and Staphylococcaceae. Salivary secretory IgA increased following oral colostrum administration in pre-term infants along with downregulation of interleukin (IL)-1b and IL-8. It was also observed that tumor necrosis factor (TNF)-a, and interferon-gamma (IFN-g) were significantly higher in the control group. There was no significant difference in the incidence of LOS, NEC, or VAP between pre-term infants receiving colostrum and those who did not. Secondary outcomes such as time to full enteral feeding were improved in pre-term infants receiving oral colostrum in addition to reduced hospital stays. Lastly, there was no difference in mortality between pre-term infants that received colostrum compared to those who did not.

Int J Nurs Stud 2023; 144:104527. [PMID: 37295286 DOI: 10.1016/j.ijnurstu.2023.104527] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2022] [Revised: 05/09/2023] [Accepted: 05/12/2023] [Indexed: 06/12/2023]
Abstract
BACKGROUND Preterm complications are now the second leading cause of death in children under five years of age. Colostrum is essential to prevent infection and promote maturation in preterm infants. Guidelines recommend that preterm infants be fed colostrum by the oral and pharyngeal routes as early as possible after birth to provide immune protection; however, due to disease and an uncoordinated sucking and swallowing function, it is challenging to provide colostrum through the oropharyngeal route, which limits the immune protection it provides. OBJECTIVE To update the existing meta-analysis, evaluate the effect of oropharyngeal colostrum administration on related outcomes in preterm infants and explore the optimal frequency and duration of oropharyngeal colostrum administration through subgroup analysis. METHODS The Cochrane Library, PubMed, Web of Science, ScienceDirect, and Ovid databases were searched for randomized control trials (RCTs) of oropharyngeal colostrum administration for preterm infants. Two researchers screened the literature strictly according to the inclusion and exclusion criteria and evaluated the quality. Primary data and data from the included literature were extracted. Finally, the data were statistically analyzed by the Review Manager 5.3 software. RESULTS A total of 1736 preterm infants were included in 16 RCTs. The meta-analysis showed that the incidence of necrotizing enterocolitis, late-onset sepsis, feeding intolerance, and death was lower, the time to full enteral feeding was shorter, and the day of recovery to birth weight was earlier in the intervention group (oropharyngeal colostrum administration group) than in the control group, and this difference was statistically significant. Subgroup analysis: Frequency of oropharyngeal colostrum administration: The incidence of necrotizing enterocolitis and late-onset sepsis in the once every 4 h group was lower than that in the control group, and the time to complete enteral feeding was shorter. Duration of oropharyngeal colostrum administration: In the 1-3 days group and 4-7 days group, the time to full enteral feeding in the intervention group was shorter. In the 8-10 days group, the incidence of necrotizing enterocolitis and late-onset sepsis was lower in the intervention group. CONCLUSIONS Oropharyngeal colostrum administration can reduce the incidence of necrotizing enterocolitis, late-onset sepsis, feeding intolerance and mortality, shorten the time to full enteral feeding, and lead to a faster recovery to birth weight in preterm infants. The appropriate oropharyngeal colostrum administration frequency may be 4 h, and the optimal duration may be 8-10 days. Therefore, it is recommended that clinical medical staff implement oropharyngeal colostrum administration for premature infants based on existing evidence. TWEETABLE ABSTRACT Oropharyngeal colostrum administration can reduce the incidence of complications in preterm infants and shorten the time to full enteral feeding.

Pados BF. State of the Science on the Benefits of Human Milk for Hospitalized, Vulnerable Neonates. Nurs Womens Health 2023; 27:121-140. [PMID: 36871597 DOI: 10.1016/j.nwh.2023.01.008] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2022] [Revised: 12/16/2022] [Accepted: 01/26/2023] [Indexed: 03/06/2023]
Abstract
Research on human milk has increased dramatically in recent years. The purpose of this review is to describe the literature on the health benefits of human milk for hospitalized, vulnerable neonates. PubMed, CINAHL, and Embase were searched for research articles reporting the health outcomes of hospitalized neonates who were exposed to human milk. Human milk, particularly a mother's own milk, has the potential to reduce the risk of death and the risk and severity of necrotizing enterocolitis, infection, retinopathy of prematurity, bronchopulmonary dysplasia, intraventricular hemorrhage, kidney disease, and liver disease. Dose and timing of human milk is important, with more human milk and earlier introduction having a greater impact on health. When a mother's own milk is not available, donor human milk provides benefits over infant formula.

Abstract
Objective: Colostrum, the first form of human milk, is strongly encouraged for infants due to its benefits. During the early postpartum (PP) period, the secreted colostrum volume can be minimal, causing concerns among mothers about sufficient milk supply. Few studies have examined temporal changes in the colostrum. This study aimed to elucidate the trajectory of expressed colostrum volume in the first 48 hours after delivery. Materials and Methods: This was a cross-sectional observational study performed at Kagawa National Children's Hospital. One hundred five mothers who did not directly breastfeed in the first 48 hours after delivery were enrolled in the study. Well-trained midwives instructed the mothers on how to express human milk, and mothers started to express as soon as possible after delivery. Mothers were advised to express human milk every 3 hours, and the milk volume was measured. Results: Within 3 hours PP, 60% of mothers expressed milk, and the median frequency of expression was 14 (interquartile range, 11-16) times in the first 48 hours. At 0-3 and 3-6 hours PP, the volume of initially expressed milk was 0.4 (0.0-2.0) mL and 1.0 (0.0-6.0) mL, respectively. Subsequently, milk volume decreased. The volume remained low until 30 hours PP and increased dramatically; this phenomenon is termed secretory activation, which began later in primiparous women than in multiparous women. Conclusion: The decline in expressed milk volume during the early PP period caused concern among mothers. Therefore, mothers should be informed of the PP trajectory of human milk volume.
