Background:
Candida is an important cause of infections in premature infants. Gastrointestinal colonization with Candida is a common site of entry for disseminated disease. The objective of this study was to determine whether a dietary supplement of medium-chain triglycerides (MCTs) reduces Candida colonization in preterm infants.
Methods:
Preterm infants with Candida colonization (n = 12) receiving enteral feedings of either infant formula (n = 5) or breast milk (n = 7) were randomized to MCT supplementation (n = 8) or no supplementation (n = 4). Daily stool samples were collected to determine fungal burden during a 3-week study period. Infants in the MCT group received supplementation during 1 week of the study period. The primary outcome was fungal burden during the supplementation period as compared with the periods before and after supplementation.
Results:
Supplementation of MCT led to a marked increase in MCT intake relative to unsupplemented breast milk or formula as measured by capric acid content. In the treatment group, there was a significant reduction in fungal burden during the supplementation period as compared with the period before supplementation (rate ratio, 0.15; P = 0.02), with a significant increase after supplementation was stopped (rate ratio, 61; P < 0.001). Fungal burden in the control group did not show similar changes.
Conclusions:
Dietary supplementation with MCT may be an effective method to reduce Candida colonization in preterm infants.
Insights
Medium-chain triglycerides (MCTs) supplementation significantly reduced Candida colonization in preterm infants. This dietary intervention offers a promising strategy for preventing invasive Candida infections in vulnerable newborns.
Area of Science:
- Neonatal Medicine
- Infectious Diseases
- Nutritional Science
Background:
- Candida infections pose a significant threat to premature infants.
- Gastrointestinal Candida colonization is a primary route for disseminated infections.
- Effective strategies to reduce Candida colonization in neonates are crucial.
Purpose of the Study:
- To investigate the efficacy of medium-chain triglycerides (MCTs) as a dietary supplement.
- To determine if MCT supplementation reduces Candida colonization in preterm infants.
Main Methods:
- A randomized controlled trial involving preterm infants with Candida colonization.
- Infants received either MCT supplementation or no supplementation alongside standard enteral feedings.
- Fungal burden was assessed via daily stool samples over a 3-week period.
Main Results:
- MCT supplementation led to a significant reduction in Candida fungal burden during the supplementation period.
- Fungal burden increased significantly after MCT supplementation was discontinued.
- Control infants did not exhibit similar changes in fungal burden.
Conclusions:
- Dietary supplementation with medium-chain triglycerides (MCTs) demonstrates potential as an effective method.
- MCTs may help reduce Candida colonization in preterm infants.
- This approach could contribute to preventing invasive Candida infections in neonates.
