Choline Nutritional Status Of Children With Cystic Fibrosis X-Sectional Study
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.
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.

Medical and Biotech [MESH] Definitions
Cystic Fibrosis
An autosomal recessive genetic disease of the EXOCRINE GLANDS. It is caused by mutations in the gene encoding the CYSTIC FIBROSIS TRANSMEMBRANE CONDUCTANCE REGULATOR expressed in several organs including the LUNG, the PANCREAS, the BILIARY SYSTEM, and the SWEAT GLANDS. Cystic fibrosis is characterized by epithelial secretory dysfunction associated with ductal obstruction resulting in AIRWAY OBSTRUCTION; chronic RESPIRATORY INFECTIONS; PANCREATIC INSUFFICIENCY; maldigestion; salt depletion; and HEAT PROSTRATION.
Cystic Fibrosis Transmembrane Conductance Regulator
A chloride channel that regulates secretion in many exocrine tissues. Abnormalities in the CFTR gene have been shown to cause cystic fibrosis. (Hum Genet 1994;93(4):364-8)
Mice, Inbred Cftr
A strain of mice widely studied as a model for cystic fibrosis. These mice are generated from embryonic stem cells in which the CFTR (cystic fibrosis transmembrane conductance regulator) gene is inactivated by gene targeting. As a result, all mice have one copy of this altered gene in all their tissues. Mice homozygous for the disrupted gene exhibit many features common to young cystic fibrosis patients, including failure to thrive, meconium ileus, and alteration of mucous and serous glands.
Stenotrophomonas Maltophilia
A species of STENOTROPHOMONAS, formerly called Xanthomonas maltophilia, which reduces nitrate. It is a cause of hospital-acquired ocular and lung infections, especially in those patients with cystic fibrosis and those who are immunosuppressed.
Meconium Ileus
Intestinal obstruction caused by congealed MECONIUM in the distal ILEUM and CECUM. It presents shortly after birth as a failure to pass meconium and frequently occurs in infants with CYSTIC FIBROSIS.
