Nutritional State during COPD Exacerbation: Clinical and Prognostic Implications

Aims: To estimate the prevalence of malnutrition in chronic obstructive pulmonary disease (COPD) patients hospitalized for exacerbation and to evaluate its clinical and prognostic influence on the exacerbation. Subjects/Methods: The subjects were 78 consecutive patients with moderate-to-severe COPD who were admitted to hospital with a diagnosis of exacerbation. Nutritional status was assessed by means of body mass index (BMI), bioelectric impedance analysis and levels of plasmatic albumin. Previous spirometry, 6-min walk test, severity of the exacerbation, days of hospitalization and readmission in the following 3 months were also evaluated. Results: Malnutrition [BMI
