Efficacy and Safety of Omega-3 Lipid Therapy in Pediatric Patients With Parenteral Nutrition-Associated Liver Disease
29 november 2012 bijgewerkt door: Amarnath, Rathna, M.D.
This pilot study seeks to demonstrate the efficacy of an intravenous lipid preparation high in omega-3 fatty acids (Omegaven) in the treatment of cholestasis in parenteral nutrition dependent patients with short gut syndrome.

Beschrijving
Inclusion Criteria:

Exclusion Criteria:
- Liver dysfunction secondary to cause other than PN verified by standard of care diagnostic procedures and lab work to rule out alternative causes of neonatal cholestasis.

Experimenteel: Omegaven Therapy
After baseline labs, which have been collected no earlier than seven days prior to the initiation of therapy are obtained, therapy with Omegaven will be initiated at a starting dose of 0.5 g/kg/day infused over 12 hours.
If tolerated, the dose will be increased to 1 g/kg/day, the goal dose.
Omegaven will be infused intravenously through either a central or peripheral catheter in conjunction with parenteral nutrition.

Primaire uitkomstmaten
Uitkomstmaat |
Maatregel Beschrijving |
Tijdsspanne |
|---|---|---|
|
Improvement of liver dysfunction as measured by time to achieve 50 % decrease in direct bilirubin
Tijdsspanne: weekly then biweekly data collection
|
Direct bilirubin will be collected at baseline, then weekly for 30 days, and then biweekly, thereafter, up to an expected average of 108 weeks
|
weekly then biweekly data collection
|
Secundaire uitkomstmaten
Uitkomstmaat |
Maatregel Beschrijving |
Tijdsspanne |
|---|---|---|
|
a) Maintenance of nutritional status
Tijdsspanne: Labwork will be collected at baseline, then weekly for the first month. Thereafter, a lipid panel will be collected every 2 months, complete metabolic panel every 2 weeks, and essential fatty acid profile monthly, up to an expected average of 108 weeks
|
Nutritional status will be monitored by reviewing complete metabolic panel, magnesium, weight, vitals, phosphorus, prealbumin, lipid panel, and essential free fatty acid profile.
The essential fatty acid profile will be checked at baseline and then monthly for at least 6 months until the patient is determined to be receiving at least 2.7% of caloric intake from linoleic acid.
If the patient's essential fatty acid profile indicates that the patient is absorbing adequate amounts of essential fatty acid, the essential fatty acid profile will be discontinued .
|
Labwork will be collected at baseline, then weekly for the first month. Thereafter, a lipid panel will be collected every 2 months, complete metabolic panel every 2 weeks, and essential fatty acid profile monthly, up to an expected average of 108 weeks
|
|
Occurrence of potential adverse side effects
Tijdsspanne: biweekly labwork up to an expected average of 108 weeks
|
Adverse events may include but are not limited to prolonged prothrombin time, hypertriglyceridemia, and anaphylaxis in relation to the patient's therapy.
|
biweekly labwork up to an expected average of 108 weeks
|
|
c) Resolution of liver dysfunction
Tijdsspanne: weekly complete metabolic panel for the first month and then biweekly thereafter, up to an expected average of 108 weeks
|
Resolution of liver dysfunction will be defined by achievement of normal direct bilirubin, aspartate aminotransferase and alanine transaminase.
|
weekly complete metabolic panel for the first month and then biweekly thereafter, up to an expected average of 108 weeks
