ChylothoraxNCT02143557
Dietary Treatment of Infants With Chylothorax
A study testing Fat-Modified Breast Milk and MCT formula in people with Chylothorax, run by The Hospital for Sick Children at 1 site in Canada.
Trial summary
Chylothorax occurs in ~3 to 5 % of infants undergoing cardiac surgery. Standard treatment requires discontinuation of breast milk feeding, due to the abundance of long chain triglycerides, and transition to a medium chain triglyceride (MCT) based formula. Read more about this study

About this study
Official title: The Effectiveness of Low Fat Breast Milk for the Treatment of Chylothorax in Infants Following Cardiothoracic Surgery: A Pilot Study
Chylothorax occurs in ~3 to 5 % of infants undergoing cardiac surgery. Standard treatment requires discontinuation of breast milk feeding, due to the abundance of long chain triglycerides, and transition to a medium chain triglyceride (MCT) based formula. Objective: To determine the effectiveness of fat-modified breast milk (MBM) for the treatment of chylothorax compared with MCT-formula. Hypothesis: The investigators primary hypothesis was that infants fed MBM would have more chyle drainage in the first 5 days after diagnosis compared to infants fed an MCT based formula which is the current standard of care. Design: Infants with chylothorax were eligible. Treatment infants (n=8) received mother's own milk that had been modified by removing the fat layer via centrifugation and adding MCT and nutrients to provide 67 kcal/mL and 11 g/100 mL protein (MBM group). Control infants (n=8) received an MCT-formula (MCT group). The feeding intervention was a minimum of 6 weeks after chest tube removal per The Hospital for Sick Children standard chylothorax treatment protocol. Outcome measures collected included chyle drainage from chest tubes, weight, length and head circumference measurements and estimated energy and nutrient intake.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Fat-Modified Breast MilkOther
MCT formulaOther
| Study group | Role | What they receive |
|---|---|---|
| Fat-Modified Breast Milk | Experimental | Infants in this arm of the study were fed their own mother's breast milk where the fat layer was removed by centrifugation. Prior to feeding, extra energy and nutrients were added to the defatted breast milk. Receives: Other: Fat-Modified Breast Milk |
| MCT-formula group | Active comparator | Infants in this arm of the study were fed a MCT-containing medical food which is the current standard of care. Receives: Other: MCT formula |
What is being measured
The primary outcome is the main question the study is designed to answer.
Chyle Drainage from Chest Tubes
This outcome includes measurement of chyle drainage from chest tubes in the first 5 days after diagnosis of chylothorax and the number of days of chest tube drainage.
Measured: 6 weeks of chylothorax treatment
Secondary outcomes (1)
Growth
Infant weight, length and head circumference measurements were determined at study initiation and at the first post-discharge follow-up visit (within one-week of discharge) and again at the end of chylothorax treatment.
Measured: 6 weeks of the chylothorax treatment
