Nutritional Status in Patients With Acute Exacerbation of Chronic Obstructive Pulmonary Disease
- Conditions
- Pulmonary Disease, Chronic Obstructive
- Registration Number
- NCT03709498
- Lead Sponsor
- Evangelismos Hospital
- Brief Summary
A cross sectional observation study of body composition in COPD patients consecutively hospitalized with acute exacerbation.
- Detailed Description
Skeletal muscle dysfunction and changes in body composition are important extra-pulmonary manifestations of chronic obstructive pulmonary disease (COPD) that occur in all stages of disease and are associated with poor outcome. In patients with COPD, bioelectrical impedance analysis (BIA) has usually been used to estimate fat-free mass (FFM) and body composition through predictive equations. Very few studies had focused on raw BIA data. The aim of this study is first describe the measurement of phase angle in patients with with acute exacerbation and second to determine the validity of phase angle in this group by assessing its relationship with established markers of function, disease severity and prognosis.

Study & Design
- Study Type
- OBSERVATIONAL
- Study Design
- Not specified
- Primary Outcome Measures
Name Time Method Phase Angle 1 month The evaluation of phase angle will be performed by means of the electric bioimpedance apparatus. The measurements will be obtained with the patient in dorsal decubitus, barefoot, with the lower limbs slightly apart and without metal objects attached to the body, with electrodes placed on the right hand and foot.
- Secondary Outcome Measures
Name Time Method Forced expiratory flow volume in one second (FEV1). 1 month Forced expiratory flow volume in one second following standards recommended by European Respiratory Society and correlation with muscle mass.
Length of Hospital Stay (LOS) 1 month Duration of Hospital Stay
Body Composition 1 month. Body composition will be assessed using bioelectrical impedance analysis (In Body 720, Biospace) at a standardized time after breakfast. Bioelectrical impedance analysis (BIA) is a simple, safe, non-invasive method to measure assess lean (e.g., muscle) vs. fat body compartments. Fat-free mass will be calculated by using disease-specific equations as described by Schols. Fat mass will then be calculated as total body weight minus fat-free mass. Such BIA measurements are accurate, comparable to other techniques used to assess body composition, and have been validated in patients with acute excerbation of COPD
Change in Forced vital capacity (FVC) 1 month Secondary endpoint will be the correlation between FVC and muscle mass.
Correlation between phase angle and serum CRP levels. 1 month Detect the serum CRP levels and then analyze the correlation between CRP and phase angle measurement.
Phase Angle 2 months The evaluation of the phase angle will be performed by means of the electric bioimpedance apparatus. The measurements will be obtained with the patient in dorsal decubitus, barefoot, with the lower limbs slightly apart and without metal objects attached to the body, with electrodes placed on the right hand and foot.
