[Legionellosis at intensive care units: study of 30 cases]
Abstract:
A prospective study during 44 months has been carried out in order to establish the incidence of pneumonia due to Legionella sp. in our hospital's intensive care unit (ICU). Thirty cases of legionellosis were diagnosed (22.2% of the studied pneumonias) two of them were acquired in the ICU and 76.6% were caused by L. pneumophila serotype. The most evident symptomatology was intense dyspnea, neurological disorders, acute respiratory and renal failure. The biochemical alterations, most commonly encountered were increased liver enzymes, hypoxemia, hypoalbuminemia, increased urea, creatinine and hematuria. As a consequence of this severe disease, the mortality rate was high (13 out of 30 cases).
Insights
Legionella pneumonia is a significant threat in intensive care units (ICUs), causing severe symptoms and high mortality. This study highlights the incidence and characteristics of Legionella infections in hospitalized patients.
Area of Science:
- Infectious Diseases
- Pulmonology
- Critical Care Medicine
Context:
- Prospective study conducted over 44 months in a hospital intensive care unit (ICU).
- Focus on identifying the incidence of pneumonia caused by Legionella species.
Purpose:
- To determine the incidence of Legionella-related pneumonia in the ICU setting.
- To characterize the clinical presentation, biochemical alterations, and outcomes of legionellosis.
Summary:
- Thirty cases of legionellosis were diagnosed, representing 22.2% of studied pneumonias.
- Most cases (76.6%) were caused by Legionella pneumophila serotype.
- Key symptoms included severe dyspnea, neurological issues, and acute respiratory/renal failure. Common biochemical findings were elevated liver enzymes, hypoxemia, hypoalbuminemia, and renal dysfunction.
Impact:
- Legionellosis is a severe condition with a high mortality rate (13 out of 30 cases in this study).
- Findings underscore the importance of recognizing and managing Legionella infections in critical care settings.
