[Prognostic role of body composition in patients with pneumonia associated with decompensated CHF]

Abstract

Aim: To evaluate the effect of body composition on prediction of community-acquired pneumonia caused by Str. pneumoniae in patients with decompensated CHF.

Materials and methods: The study included 216 patients. The pneumonia agent was identified by sputum culture. Body composition with determining lean body mass and fat mass was evaluated using a bio-impedance analysis; body mass index (BMI) was calculated. Patients with BMI 18.5-24.9 kg/m2 were included into the study. Statistical analysis of obtained data was performed using the IBM SPSS Statistics 20 software.

Results: The in-hospital mortality was 13.4 %; the one-year mortality was 29.6 %. Fat mass strongly, negatively correlated with a fatal outcome within a year, and the degree of lean body mass shortage moderately, positively correlated with the life span of patients.

Conclusion: Body composition is significantly predictive for patients with decompensated CHF and community-acquired pneumonia caused by Str. pneumoniae.
