“…This effect has been demonstrated experimentally but its clinical relevance is unclear. 31 The small volume supplement we used was designed to reduce any impact this might have and be easy for patients to tolerate. Studies using this supplement have indicated there are no short term adverse effects on ventilation or respiratory quotient in COPD patients.…”

Background: Pulmonary rehabilitation is effective in improving exercise performance and health status in chronic obstructive pulmonary disease (COPD). However, the role of nutritional support in the enhancement of the benefits of exercise training has not been explored. A double blind, randomised, controlled trial of carbohydrate supplementation was undertaken in patients attending outpatient pulmonary rehabilitation. Methods: 85 patients with COPD were randomised to receive a 570 kcal carbohydrate rich supplement or a non-nutritive placebo daily for the duration of a 7 week outpatient pulmonary rehabilitation programme. Primary outcome measures were peak and submaximal exercise performance using the shuttle walk tests. Changes in health status, body composition, muscle strength, and dietary macronutrient intake were also measured. Results: Patients in both the supplement and placebo groups increased shuttle walking performance and health status significantly. There was no statistically significant difference between treatment groups in these outcomes. Patients receiving placebo lost weight whereas supplemented patients gained weight. In well nourished patients (BMI >19 kg/m

“…Collectively, this indicates a hypermetabolic state that may contribute to weight loss if energy requirements are not fully met and provides a convincing rationale for caloric supplementation to maintain or increase fat mass. Early concerns about adverse effects of carbohydrate supplementation in COPD due to increased carbon dioxide production, resulting from carbohydrate oxidation loading ventilation, have not been substantiated in more recent studies but were only observed after hyperalimentation [32]; this is, in practice, unlikely to happen with oral nutrition, especially in patients with poor appetite, and can easily be avoided by smaller meal portions well spread over the day.…”

Nutritional assessment and therapy in COPD: a European Respiratory Society statement

Nutrition and metabolism have been the topic of extensive scientific research in chronic obstructive pulmonary disease (COPD) but clinical awareness of the impact dietary habits, nutritional status and nutritional interventions may have on COPD incidence, progression and outcome is limited. A multidisciplinary Task Force was created by the European Respiratory Society to deliver a summary of the evidence and description of current practice in nutritional assessment and therapy in COPD, and to provide directions for future research. Task Force members conducted focused reviews of the literature on relevant topics, advised by a methodologist. It is well established that nutritional status, and in particular abnormal body composition, is an important independent determinant of COPD outcome. The Task Force identified different metabolic phenotypes of COPD as a basis for nutritional risk profile assessment that is useful in clinical trial design and patient counselling. Nutritional intervention is probably effective in undernourished patients and probably most when combined with an exercise programme. Providing evidence of costeffectiveness of nutritional intervention is required to support reimbursement and thus increase access to nutritional intervention. Overall, the evidence indicates that a well-balanced diet is beneficial to all COPD patients, not only for its potential pulmonary benefits, but also for its proven benefits in metabolic and cardiovascular risk. @ERSpublications Metabolism and nutrition: shifting paradigms in COPD management

“…В совокупности это означает гиперме таболическое состояние, которое может вносить дополнительный вклад в снижение МТ, если потреб ности в энергии не удовлетворяются полностью, и стать причиной усиленного восполнения калорий, направленного на сохранение или увеличение ЖМ. Боязнь побочных эффектов углеводных пищевых добавок при ХОБЛ вначале была связана с повыше нием продукции углекислого газа в результате окис ления углеводов, что может создавать дополнитель ную нагрузку на вентиляцию, однако в последующих исследованиях это не подтвердилось и наблюдалось только после переедания [32]. Практически такая ситуация вряд ли возможна при пероральном пита нии, особенно у людей с плохим аппетитом, и этих осложнений можно легко избежать при частом дроб ном питании малыми порциями.…”
