Measurement of body composition • Regional • MRI Scan } muscle, fat distribution • Dexa Scan } lean, FM, bone mass • (trunc, extremities) • Whole body • Dexa scan } lean, FM, bone mass • Skinfold thickness } FM • Bioelectrical impedance } TBW > FFM
Body composition and COPD subtypes and healty volunteers Conclusion; skeletal muscle weakness i associated with wasting of extremity FFM in COPD patients, independent of air-flow obstruction and COPD subtype Am J Clic Nutr 2000; 71:733-8
Wasting pattterns and survival • Cachexia= Low BMI + Low FFMI • Sarcopeni=Low FFMI • Semistarvation= Low BMI Semistarvation Sarcopeni cachexia Schols AJCN 2005
Body composition, disease severity and mortality • Loss of FFM despite a normal BMI in(Gold stage 2+3) • Highest prevelance of cachexiain Gold stage 4 • Differances between emphysema and chronic bronchitis = Fat mass • FFM is a better predictor of survival than BMI Am J Clin Nutr 2005; 82:53-9
In patients with COPD weight loss and muscle atrophy • Respiratory and peripheral muscle functions, • Exercise capacity • Health Related Quality of Life • Mortality rates effected negatively 1-Eur Respir J 1994;7:1793-97 2-Eur Respir J 1997;10:2807-13 3-Eur Respir J 1997;10:1575-80 4-Am J Clin Nutr 2005;82:53-9

Rehabilitation Body composition
High intensity training in COPD patients is feasible and effective despite ventilatory limitation Endurance + Strength • Endurance training: ↑ muscle oxidative capacity ↑ exercise performance • Strength training: ↑ muscle mass ↑ Quadriceps strength ■ ↑Exercise performance ■ ↑ Muscle strength ■ ↑ Muscle mass, ↓Fat mass
Suboptimal training intensity in advance COPD • Patients are unable to participate in training program due to; • Severe dyspnea or gase exchange disturbances, • Too disabled, • Fear, anxiety • Weigth loss and muscle catabolism associated with exacerbation or episodes of respiratory failure lead to major functional decline exercise is difficult or imposible
Despite high exercise intensity: • No effect of exercise traning per se on body weight and muscle mass in COPD patients with cachexia Schols AJRCCM 1995

Nutritional supplementation Restore energy balance and stimulate anabolism • Balance (elevated) energy requirements • Stimulate protein synthesis Enhance efficacy of other interventions; Exercise, anabolic steroids

Nutrional support is feasible and effective during rehabilitation to improve weight and body composition • Schols (AJRCCM 1995) • Positive effects on weight, FM and FFM relative to rehabilitation alone • Creutzberg (Nutrition 2000) • Gains in weight, fat, FFM, muscle functions, exercise capacity • Patients using systemic steroids less responsive • Steiner (Thorax 2004) • Positive effects on weight, FM and exercise capacity relative to rehabilitation alone, particularly in normal weight subjects • Broekhuizen (Thorax 2005) • Gains in weight, FM, FFM, muscle functions, exercise capacity
Is Pulmonary rehabilitation alone sufficient to improve body weight and composition in depleted COPD patients ?Creutzberg et al. Nutrition 2003 • No effect of exercise traning per se on body weight and muscle mass in COPD patients with cachexia Plasebo 8 Nutritional support 6 4 NS NS 2 P 0 Body weight P -2 FFM

Content, amount and macronutrients in oral nutritional supports VAS Skoru (mm) Postprandial süre • Metabolic and ventilatory response to low caloric nutrients are much more better, • High CH content provide improvements in respiratory functions, and reduced dyspnea Am J Clin Nutr 2001;73:295-301

Effects; • Stimulates appetite in depleted COPD patients with improvements in body composition • ↑ FM, no effect on FFM • Reductions in exercise capacity • Reductions in plasma cortisol ve testesterone Results; not very encouraging Chest 2002;121:1070-78
Whole body protein breakdown has increased in cachectic COPD patients Conclusion; losses in myofibriller proteins must be the target in nutritional and pharmacological interventions Rutten, AM J Clin Nutr
Anabolic nutritional modulation; Amino acids • Branched-chain amino acids; Leucine,isoleucine, valine • Precursor • Upregulates protein syntesis in skeletal muscles
Anabolic nutritional modulation; • GLUTAMAT; - An important precursor for antioxidant glutathione and glutamine in muscles • Decreased Glutamat and glutathione levels were found in skeletal muscles of patients with emphysema • İntermediates to preserve high-energy phosphates at rest .Lactic asidosis may occur in the absence Am J Respir Crit Care Med 2001; 163:859-64

Conclusions; • Weight loss and reductions in FFM are important predictors of disease progression, resulted in reductions in exercise capacity, increases in mortality and morbidities in COPD patients . • Nutritional support reverses the effects of hypermetabolism and negative energy balance that resulted weight loss. • With the addition of high caloric main menu,enteral nutrients must be used small sized porsions but frequantly in stable COPD patients.
