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 supply a choline supplement to children with CF to see if their nutrition and methyl status can be improved.
This will be a prospective, repeated measures study involving 34 children with CF who will take a supplement of water soluble choline bitartrate, 2 gm/day with meals for 6 months. The baseline (day 0) results for each child will serve as his/her own control, and assessments will be made at 3 months and 6 months choline supplementation and again 3 months after stopping choline.
The supplement will be provided as capsules containing 250 mg choline bitartrate. 4 capsules will be taken with or immediately before each of two meals per day: breakfast and dinnertime meals, providing 1 gm of supplemental choline each day.
The children will be enrolled by description of the project to the child and their parent(s) at a CF clinic appointment. Body weight, height and blood pressure 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. The hematology and clinical chemistry will be done by the Hematopathology and Clinical Chemistry labs at the B.C.'s Children's Hospital. CF genotype, gender, birth date, hematology, clinical chemistry, anthropometry, nutritional measures, pulmonary function test results, chest X-Ray and/or CT scans, pancreatic function test results (fecal elastase, chymotrypsin or secretin-CCK), medications and supplements (including enzymes, vitamins, minerals, nutrition supplements & Natural Health Products) and where available, liver ultrasound and biopsy reports will be collected from chart data. Information in the subject's medical charts relating to antibiotic therapy, duration of illnesses, hospitalization and diagnosis will be reviewed to ensure the inclusion/exclusion criteria are met.
Assessment of pulmonary function by computer assisted spirometry which includes the measures of forced vital capacity (FVC), forced expiratory volume in one second (FEV1) and forced mid-expiratory flow (FEF 25-75) is completed for all children as part of each regularly scheduled clinic visit and the results collected for this study.

There are many challenges to providing end-of-life care (EOLC) to people with cystic fibrosis (CF).
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.
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)
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.
A condition produced by a deficiency of CHOLINE in animals. Choline is known as a lipotropic agent because it has been shown to promote the transport of excess fat from the liver under certain conditions in laboratory animals. Combined deficiency of choline (included in the B vitamin complex) and all other methyl group donors causes liver cirrhosis in some animals. Unlike compounds normally considered as vitamins, choline does not serve as a cofactor in enzymatic reactions. (From Saunders Dictionary & Encyclopedia of Laboratory Medicine and Technology, 1984)
Donor of choline in biosynthesis of choline-containing phosphoglycerides.
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
