REGUEIRO-MIRA, María Virtudes et al. Prognostic factors in adult patients hospitalized for pneumonia caused by Legionella pneumophila. Rev. chil. infectol. [online]. 2015, vol.32, n.4, pp.435-444. ISSN 0716-1018.  http://dx.doi.org/10.4067/S0716-10182015000500010.

Introduction: Legionellosis is a multisystem bacterial disease, which causes pneumonia with high mortality in patients with comorbidity and admitted in intensive care units (ICU). Objective: Determine predictors of mortality or ICU admission. Methods: Retrospective follow-up of patients diagnosed with Legionella pneumophila pneumonia in Complexo Hospitalario Universitario de A Coruña. Period 2000-2013 (n = 240). Analysis of multivariate logistic regression was performed. Results: Mean age was 57.2 ± 15.4 years old, 88.3% were male. Average score of comorbidity (Charlson score) was 2.3 ± 2.3. There was a clear seasonal variation. Predominant symptoms were fever (92.5%), dry cough (38.1%) and dyspnea (33.9%). Creatinine clearance was lower than 60 mL/min/1.73 m2 in 29.7% and sodium < 135 mEq/l in 58.3%. Admission to ICU rate was 16.3% and 10.8% needs mechanical ventilation. Inhospital mortality rate was 4.6%, rising to 23.1% in patients admitted to ICU. Variables associated to predict ICU admission were age (OR = 0.96), liver disease (OR = 7.13), dyspnea (OR = 4.33), delirium (OR = 5.86) and high levels of lactatedehydrogenase (OR = 1.002). Variables associated with inhospital mortality were Charlson index (OR = 1.70), mechanical ventilation (OR = 31.44) and high levels of lactatedehydrogenase (OR = 1.002). Discussion: Younger patients with liver disease, dyspnea and confusion are more likely to be admitted to ICU. Comorbidity, mechanical ventilation and elevated LDH levels are associated with higher mortality rate.
