Abstract
BACKGROUND: Various criteria have been used so far for the diagnosis of malnutrition or sarcopenia in patients suffering from chronic obstructive pulmonary disease (COPD). OBJECTIVE: To determine the prevalence of malnutrition and sarcopenia in COPD, as defined by international diagnostic criteria, and determine their relationships with raw BIA variables. METHODS: Two-hundred and sixty-three COPD patients (185 males and 78 females) underwent both clinical examination and respiratory, anthropometric, bioelectrical impedance analysis (BIA raw variables: phase angle and impedance ratio), handgrip strength (HGS), 4 m gait speed and biochemical measurements. Malnutrition and sarcopenia were diagnosed based on European Society for Clinical Nutrition and Metabolism (ESPEN) criteria and European Working Group on Sarcopenia in Older People (EWGSOP) criteria, respectively. RESULTS: The overall prevalence of malnutrition and sarcopenia was 19.8% and 24.0% respectively, increasing with disease severity. The prevalence of sarcopenia was significantly higher in patients with malnutrition (71.2% vs 12.3%; p < 0.001), especially in those with systemic inflammation (cachectic patients) (85.7% vs 61.3%; p < 0.001). Malnourished patients with sarcopenia had a significant reduction in BMI, fat-free mass and HGS compared to non-sarcopenic patients. Finally, impedance ratio significantly increased and phase angle decreased in patients with severe sarcopenia and in cachectic patients. CONCLUSION: A relatively high prevalence of malnutrition and sarcopenia was found in COPD patients applying international standard criteria, with some discrepancy between the two diagnoses. In addition, clear-cut changes in raw BIA variables were observed in malnourished patients with systemic inflammation and sarcopenic patients.
