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.
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.
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.
Dietary supplementation with MCT may be an effective method to reduce Candida colonization in preterm infants.
念珠菌是早产儿感染的重要原因。胃肠道定植念珠菌是播散性疾病的常见入口。本研究的目的是确定中链甘油三酯 (MCT) 的膳食补充是否可以减少早产儿的念珠菌定植。
患有念珠菌定植的早产儿(n=12)接受婴儿配方奶粉(n=5)或母乳(n=7)的肠内喂养,随机分为 MCT 补充组(n=8)或无补充组(n=4)。在为期 3 周的研究期间,每天收集粪便样本以确定真菌负担。MCT 组的婴儿在研究期间的 1 周内接受补充。主要结局是与补充前和补充后相比,补充期间的真菌负担。
MCT 的补充导致以辛酸含量衡量的 MCT 摄入量相对于未补充的母乳或配方奶显著增加。在治疗组中,与补充前相比,补充期间的真菌负担显着降低(比率比,0.15;P=0.02),补充停止后显着增加(比率比,61;P<0.001)。对照组的真菌负担没有显示出类似的变化。
MCT 的饮食补充可能是减少早产儿念珠菌定植的有效方法。
