Choline Nutritional Status Of Children With Cystic Fibrosis X-Sectional

Status Completed

Clinical Trial Summary

Cystic fibrosis (CF) is the most common lethal, inherited disorder among Caucasians. Choline is an essential vitamin and as a methyl donor is critically needed to support the normal metabolism. Our previous studies have demonstrated that children with CF have depleted levels of choline. The purpose of this study is to gather data on the status of choline and related metabolites in children with Cystic Fibrosis by age and gender. The hypothesis for this study is that in children with CF, deficiency of choline and related metabolites will increase with increasing age.

Clinical Trial Description

The objective of this clinical project is to determine the status of choline and related metabolites in a large group of children with Cystic Fibrosis (CF). Based on the results it will be possible to determine which children are deficient or at risk for choline deficiency, and might benefit most from supplementation to sustain improvement in the plasma choline, and its metabolites. This will be a cross-sectional study that will, over a 6 month period, look to enroll as many patients as possible from 140 children with CF who are seen regularly at the CF Clinic at B.C.'s Children's Hospital. The study will involve the collection of blood and urine at the time of a scheduled appointment. All procedures for enrollment, collection of chart data and blood samples will follow procedures used in our previous studies. Body weight and height will be measured and routine blood work including liver enzymes, hematology, serum zinc, selenium and vitamins A and E will be completed as part of the clinic appointment. CF genotype, gender, birth date, hematology, clinical chemistry, anthropometric and nutritional measures, liver ultrasound, biopsy reports where available, pancreatic function (elastase, chymotrypsin/secretin-CCK) and all medications including mineral, vitamin and nutritional and enzyme supplements will be recorded from chart data. Blood samples will be used for analyses of choline and its metabolites and various biomarkers in redox pathways. A urine sample will be collected and used to assay excretion of related metabolites. Creatine will be analyzed to avoid the need for quantitative 24 hour urine collection. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
