Oral protein energy supplements for children with cystic fibrosis: CALICO multicentre randomised controlled trial. Failure of conventional strategies to improve nutritional status in malnourished adolescents and adults with cystic fibrosis. Protein-energy oral supplementation in malnourished nursing-home residents. A controlled trial.
To determine whether oral protein energy supplements, used long term in children with cystic fibrosis who are moderately malnourished, improve nutritional and other outcomes.
                Multicentre randomised controlled trial.
                Seven specialist paediatric cystic fibrosis centres and their associated shared care clinics and seven smaller paediatric cystic fibrosis clinics.
                102 children with cystic fibrosis, aged between 2 and 15 years, who were moderately malnourished.
                Oral protein energy supplements in addition to usual dietary advice compared with dietary advice alone, for 12 months.
                Change in body mass index centile over one year.
                Use of supplements was not associated with a change in body mass index centile (mean difference 2.99 centile points, 95% confidence interval -2.70 to 8.68) or other nutritional and spirometric outcomes in this group of children.
                Long term use of oral protein energy supplements did not result in an improvement in nutritional status or other clinical outcomes in children with cystic fibrosis who were moderately malnourished. Oral protein energy supplements should not be regarded as an essential part of the management of this group of children.
                ISRCTN: 95744468. The use of oral dietary supplements was compared with dietary counseling in 13 malnourished patients (3 males, mean age 18.1 years) with cystic fibrosis. Energy intake and nutritional status were evaluated over 3 months. There was no significant change in energy intake or percent ideal body weight in either group. To validate a nutritional intervention programme for elderly people living in nursing homes.
                In a prospective, randomized, controlled study of 88 residents, we determined nutritional status at day 0 and day 60 using a record of dietary intake, anthropometry, hand-grip strength and mini-nutritional assessment. Dietary intake, grip strength and body weight were also recorded at day 30. We divided subjects into four groups according to their mini-nutritional assessment score. Those with a score 24 received no oral supplementation. Those at risk of malnutrition (with a score of 17-23.5) were randomized to oral supplementation. Those with a score <17 received oral supplementation. We recorded the amount of oral supplements consumed daily.
                Compliance with oral supplementation was good, and daily intake averaged about 400 kcal. The total energy intake on day 60 was significantly higher in both of the groups that received supplements. Following supplementation, most subjects at risk of malnutrition improved their mini-nutritional assessment score and increased their weight (by 1.4 +/- 0.5 kg). Neither the mini-nutritional assessment score nor weight improved in subjects at risk of malnutrition who did not receive supplements. Supplementation in the malnourished group resulted in a mean mini-nutritional assessment score increase (from 13.9 +/- 2.6 to 17.1 +/- 3.9) and a mean weight gain of 1.5 +/- 0.4 kg.
                Oral nutritional supplements are well accepted and result in increased daily protein and energy intake, body weight and nutritional status in most malnourished patients and in those at risk of malnutrition.
Oral calorie supplements do not confer any additional benefit in the nutritional management of moderately malnourished children with CF over and above the use of dietary advice and monitoring alone. While nutritional supplements may be used, they should not be regarded as essential. Further randomised controlled trials are needed to establish the role of short-term oral protein energy supplements in people with CF and acute weight loss and also for the long-term nutritional management of adults with CF or advanced lung disease, or both.
