Intestinal failure associated liver disease is a cholestatic liver disease associated with prolonged need for parenteral nutrition that can lead to such significant complications as liver failure. In the neonatal population, infants with history of intestinal resection and short bowel syndrome are at increased risk for this disease. The investigators plan to compare two possible lipid dosing preventative strategies including a composite, fish oil lipid and soy-based lipid reduction.

Intestinal failure associated liver disease (IFALD) is a cholestatic liver disease associated with prolonged need for parenteral nutrition. This disease can lead to such serious complications as liver failure and need for transplantation. In the neonatal population, short bowel syndrome, due to intestinal resection, is the most common cause of intestinal failure. While the exact cause is yet to be determined, it is felt the lipid component of parenteral nutrition is a large contributor to the development of this disease. Currently, there is no standard preventative strategy to attempt to decrease the risk of IFALD in the high risk, post-surgical neonatal population. The investigators aim to complete a randomized trial comparing two possible preventative strategies. One group will receive a composite lipid containing fish oil (Smoflipid) and the other group will receive soy-based lipid at reduced dosing.
- Drug: Lipid Emulsions, Intravenous
- Intravenous lipid containing soy, MCT, olive, and fish oils
- Drug: Intralipid, 20% Intravenous Emulsion
- Intravenous lipid emulsion of 20% soy oil
Arms, Groups and Cohorts
- Active Comparator: Composite fish oil lipid (Smoflipid)
- Patients randomized to this arm will receive the composite fish oil lipid, Smoflipid, at standard dosing up to 3 g/kg/day. Patients will be started on a dose of 1 g/kg/day and titrated up to maximum dose. As enteral nutrition is advanced the lipid dose will be weaned per study protocol and dietary recommendations.
- Active Comparator: Soy-based lipid reduction
- Patients randomized to this arm will receive soy-based lipid (Intralipid) at a dose of 1 g/kg/day throughout their enrollment in the study.
Clinical Trial Outcome Measures
- Time Frame: During enrollment in study, up to maximum of 12 weeks or 84 days
- Direct bilirubin > 2 mg/dL on two measurements 5 to 7 days apart.
- Growth velocity
- Time Frame: Patients weight will be measured on a daily basis while they are randomized in the study. Their weight will be recorded into the study documentation on a weekly basis up to a maximum of 12 weeks or 84 days.
- Change in weight as measured by grams over time
- Growth velocity
- Time Frame: Length will be measured and recorded in the study documentation on a weekly basis up to a maximum of 12 weeks.
- Change in length as measured by centimeters over time
- Growth velocity
- Time Frame: Head circumference will be measured and recorded in the study documentation on a weekly basis up to a maximum of 12 weeks.
- Change in head circumference as measured in centimeters over time
- Maximum total calories from enteral intake
- Time Frame: Total daily calories will be calculated for each patient for the entire time enrolled in the study, or a maximum of 12 weeks.
- Maximum daily caloric intake from enteral intake as calculated by percentage of daily caloric intake.
- Essential fatty acid deficiency
- Time Frame: Patients will have essential fatty acid panels obtained at minimum every four weeks while enrolled in the study up to a maximum of 12 weeks.
- Triene: tetraene ratio > 0.05
- Difference in liver enzymes
- Time Frame: Hepatic function panel and GGT will be obtained every 2 weeks while enrolled up to a maximum of 12 weeks.
- Patients will have transaminase (AST, ALT), alkaline phosphatase, and gamma glutamyl transferase obtained every 2 weeks while enrolled in the study. These values will be recorded for each patient and the differences compared between the two groups.
- Complications of prematurity
- Time Frame: Diagnoses will be documented for entirety of hospitalization, from randomization and enrollment until discharge from the hospital, up to a maximum of 12 months of age.
- Each patient will have their comorbid diagnoses documented with specific interest to retinopathy of prematurity and chronic lung disease or bronchopulmonary dysplasia.
- Triglyceride concentration
- Time Frame: Triglyceride level will be obtained at a minimum of every one week for the entire enrollment of the study up to a maximum of 12 weeks.
- All enrolled patients will have triglyceride levels monitored weekly. If levels are found to be >250 mg/dL in any patient, their lipid dose will be decreased.
- Length of stay
- Time Frame: Length of stay will be calculated based on documenting each patient’s admission date, date leaving NICU, and date discharged from the hospital and calculating length of time between each date. An estimated maximum length of time would be 12 months.
- The length of stay, including time in Neonatal Intensive Care Unit (NICU) and entire hospitalization will be documented for each patient.
- Two year development
- Time Frame: ASQ will be completed anytime during the second year of life from 2 years 0 days to 2 years 364 days of chronologic age.
- At two years of chronologic age ASQ will be completed by family.
