This study involves children with CF who will take a water soluble vitamin supplement of choline bitartrate, 2 gm per day with meals.
Dietary Supplement: Vitamin: Choline Bitartrate (2-hydroxyethyl) trimethylammonium salt 1:1
This is a prospective, repeated measures study involving children with Cystic Fibrosis. Children will be assessed (1) before starting the choline supplement, (2) after taking the supplement for 6 months and after the supplement has been discontinued for 3 months.
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.
