- W2074653669 abstract "La prévalence de la dénutrition est élevée chez le patient BPCO. L'état nutritionnel est étroitement corrélé à la survie du patient BPCO, indépendamment de la fonction respiratoire. Même si un indice de masse corporelle abaissé est associé à un risque de mortalité plus élevé, les études de population ont mis en évidence que le facteur prédictif de survie le plus puissant était la masse maigre. De ce fait la mesure de la composition corporelle constitue une étape essentielle de l'évaluation clinique du patient BPCO. L'impédancemétrie bioélectrique monofréquence apparaît comme la méthode de choix pour la mesure de la composition corporelle, du fait de sa simplicité, de son moindre coût et de sa reproductibilité. Néanmoins, certaines études ont suggéré que l'absorptiométrie biphotonique aux rayons X (DEXA) et la tomodensitométrie computérisée permettaient une bonne évaluation de la masse musculaire chez le patient BPCO. Malgré leurs imperfections, la mesure du poids, l'indice de masse corporelle et l'anthropométrie gardent une place essentielle dans l'évaluation nutritionnelle des patients BPCO. Chronic obstructive pulmonary disease (COPD) is associated with a high prevalence of malnutrition. Malnutrition is a predictive factor of overall mortality in COPD, independently of respiratory function. Although a low body mass index is associated with a high mortality rate, population-based studies have shown that the strongest predictive factor of survival in COPD was the fat-free mass. The determination of body composition therefore constitutes a pivotal step in the clinical assessment of COPD patients. Single-frequency bioelectrical impedance analysis appears to be the most convenient tool for the assessment of body composition, because it is an easy, inexpensive, and highly reproducible method. Nevertheless it has been suggested that dual energy X-ray absorptiometry (DEXA) and computed tomography could be useful methods for the assessment of muscle mass in COPD. Despite the associated pitfalls, determination of weight, body mass index and anthropometric measurements remain essential parameters of nutritional assessment of patients with COPD." @default.
