Essential Fatty Acid Status & Immune Function in Parenteral Nutrition Patients

November 11, 2014 updated by: Geert Wanten
The purpose of this study is to determine if patients on long-term olive oil-based parenteral nutrition have an adequate essential fatty acid status and immune status, compared to age- and sex-matched healthy controls.

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.

Detailed Description

Patients, who suffer from severe chronic intestinal failure and whose nutritional intake cannot be met by oral food intake, have as their final option total parenteral nutrition, which contains all necessary macro- and micronutrients. Lipid emulsions are essential for these patients as they are a source of non glucose fuel calories, and they contain (essential) fatty acids which are important as structural component for many cells in the human body. Home parenteral nutrition patients are at risk for essential fatty acid deficiency. Data are lacking that indicate the optimal amount of essential fatty acids required for these patients. The latter seems especially relevant for patients receiving lipid prescriptions which are low in essential fatty acids, like ClinOleic®. Long-term parenteral nutrition dependent patients successfully use ClinOleic®. It is however unknown whether these patient remain to have an adequate essential fatty acid status in the long run.

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.

Ages Eligible for Study

18 years to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Healthy controls: volunteers who are residents in the Netherlands.

Inclusion Criteria:

  • age and sex matched healthy volunteer

Exclusion Criteria:

  • active immune modulating (underlying) disease

Cohorts and Interventions

Group / Cohort

Home parenteral nutrition patients
Patients who receive home parenteral nutrition.
Healthy controls
Those who don't receive home parenteral nutrition and consume a normal diet.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Essential fatty acid status of plasma phospholipids and peripheral blood mononuclear cells, including the biochemical determination of the Holman index (ratio of mead acid/ arachidonic acid)
Time Frame: On day of blood withdrawal
On day of blood withdrawal

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Physical examination of clinical signs/symptoms of essential fatty acid deficiency
Time Frame: On day of blood withdrawal
On day of blood withdrawal
Immune function: expression of cell surface markers, stimulus-induced reactive oxygen species production, cytokine production by leukocytes
Time Frame: On day of blood withdrawal
On day of blood withdrawal

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
December 1, 2013

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
