Hepatic Function and Bile Acid in Preterm Infants Receiving Parenteral Lipids Emulsion

February 6, 2013 updated by: Wei Cai, Shanghai Jiao Tong University School of Medicine
The etiology of parenteral nutrition-associated cholestasis(PNAC)although elusive is thought to be multifactorial, and proposed theories also include problems arising from lipid emulsions, leading us to explore alternative products available elsewhere.So we compare the different fat emulsion, and want to see if the olive oil lipid emulsions can improve hepatic tolerance in preterm infant.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Parenteral nutrition (PN) has been widely and successfully used in the pediatric population for more than 40 years, the most serious and significant life-threatening complication today continues to be parenteral nutrition-associated cholestasis(PNAC). Parenteral nutrition-associated cholestasis is indeed the most worrisome complication because it is difficult to treat and may progress to eventual cirrhosis and liver failure namely parenteral nutrition-associated liver disease (PNALD).

Two types of lipid emulsions are currently used for adult as well as pediatric patients: one lipid emulsions prepared from soybean oil that are composed of long-chain triacylglycerols (LCTs), and the other lipid emulsions composed of 50% medium-chain triacylglycerols (MCTs) and 50% LCT soybean oil. A new lipid emulsion prepared from a mixture of soybean oil and olive oil contains only LCTs and has a lower proportion (20%) of polyunsaturated fatty acids(PUFAs)and 60% monounsaturated fatty acids (MUFAs). So we compare the different fat emulsion, and want to see if the olive oil lipid emulsions can improve hepatic tolerance in preterm infant.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
