Insights
Lactoferrin supplementation shows promise in reducing late-onset sepsis (LOS) for preterm infants, though evidence quality varies. Further research is recommended to confirm these findings and improve certainty.
Area of Science:
- Neonatalogy
- Pediatric Infectious Diseases
- Nutritional Science
Background:
- Late-onset sepsis (LOS) is a significant cause of morbidity and mortality in preterm infants.
- Identifying effective preventive strategies is crucial for improving outcomes in this vulnerable population.
Purpose of the Study:
- To systematically review and meta-analyze the efficacy of lactoferrin supplementation in preventing LOS in preterm infants.
Main Methods:
- A comprehensive database search was conducted across PubMed, Web of Science, and Cochrane Central for relevant randomized clinical trials (RCTs).
- The Cochrane Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology was employed to assess the quality of evidence.
Main Results:
- Ten RCTs involving 3,679 infants were analyzed.
- Lactoferrin supplementation, with or without probiotics, significantly decreased the incidence of all LOS (RR: 0.56; 95% CI: 0.36-0.86; low certainty evidence).
- Lactoferrin supplementation without probiotics also significantly reduced all LOS (RR: 0.43; 95% CI: 0.29-0.62; moderate certainty evidence).
- No significant reductions were observed for necrotizing enterocolitis, all-cause mortality, bronchopulmonary dysplasia, or threshold retinopathy of prematurity.
Conclusions:
- Low to moderate quality evidence suggests that lactoferrin supplementation can effectively reduce the incidence of late-onset sepsis in preterm infants.
- The current evidence base necessitates further high-quality research to strengthen conclusions and guide clinical practice.
Objective:
This study aimed to systematically review and meta-analyze the role of lactoferrin supplementation to prevent late-onset sepsis (LOS) in preterm infants.
Study Design:
Database search include PubMed, Web of Science, and Cochrane central for randomized clinical trial (RCTs). The Cochrane Grading of Recommendations Assessment, Development, and Evaluation methodology was used for summarizing the results.
Results:
Ten RCTs involving 3,679 infants were included. Lactoferrin supplementation with or without probiotics decreased all LOS (relative risk [RR]: 0.56; 95% confidence interval [CI]: 0.36-0.86; I 2 = 58%; 10 studies; 3,470 subjects; level of evidence [LOE]: low) significantly. Similarly, lactoferrin supplementation without probiotics decreased all LOS (RR: 0.43; 95% CI: 0.29-0.62; I 2 = 0%; 8 studies; 1,209 subjects; LOE: moderate) significantly. Lactoferrin supplementation did not significantly reduce necrotizing enterocolitis (RR: 0.62; 95% CI: 0.29-1.33; I 2 = 43%; 6 studies; 3,079 subjects; LOE: low), all-cause mortality (RR: 0.74; 95% CI: 0.36-1.53; I 2 = 53%; 8 studies; 3,395 subjects; LOE: very low), bronchopulmonary dysplasia (RR: 1; 95% CI: 0.90-1.13; I 2 = 0%; 4 studies; 2,570 subjects; LOE: moderate), and threshold retinopathy of prematurity eligible for surgical treatment (RR: 0.61; 95% CI: 0.25-1.51; I 2 = 74%; 2 studies; 2,481 subjects; LOE: very low).
Conclusion:
Low to moderate quality evidence suggests that lactoferrin supplementation reduces LOS in preterm infants. Further research is needed to improve the certainty in the evidence.
