Vitamin E supplementation in cystic fibrosis.
Vitamin E is an antioxidant and may have a role in the protection of lung tissue against oxidative damage in cystic fibrosis. Previous studies of vitamin E status in cystic fibrosis have used plasma or serum concentrations, which vary with levels of carrier lipoproteins and hence may not reflect the concentration of vitamin E in tissues, where it is found in highest concentration in membranes. ...
متن کاملEffect of abnormal liver function on vitamin E status and supplementation in adults with cystic fibrosis.
Patients with cystic fibrosis tend to have reduced serum concentrations of vitamin E and are therefore at risk of developing the neurological complications associated with vitamin E deficiency. Improved survival in cystic fibrosis has resulted in an increasing number of older patients who may develop hepatobiliary complications which may further impair the absorption of vitamin E. In this study...
متن کاملVitamin status in treated patients with cystic fibrosis.
The water-soluble (B1, B2, B6, C, folic acid) and fat-soluble vitamin (A, carotene, E, and D) status of 36 patients with cystic fibrosis was assessed and compared with a control group of 21 age-matched normal children. Twenty-seven of the patients were receiving vitamin supplements (except folic acid and vitamin E) at the time of investigation. Vitamin B1, B2, and B6 status was adequate in all ...
متن کاملVitamin K in Cystic Fibrosis
The importance of vitamin K to coagulation is well known but there is increasing evidence that vitamin K has a diverse role in the body including the maintenance of bone health, preventing inappropriate calcification in soft tissues, and a protective role in inflammation. There is evidence that most, if not all, of these non-coagulation functions require higher dietary intakes than those requir...
متن کاملBone status in cystic fibrosis.
AIM To investigate bone mineral status of children with cystic fibrosis (CF). METHODS In 29 children with CF and 49 matched controls, bone mineral content (BMC), projected bone area (BA), and areal bone mineral density (BMD) of the whole body, total hip, and lumbar spine (L1-L4) were measured using dual energy x ray absorptiometry. The BMC values at each site were adjusted for BA, height, and...
