AbstractLegionella pneumophila is an agent also well known to be frequently responsible for severe community acquired pneumonia. Recent studies regarding severe community-acquired pneumonia have shown that Legionella pneumophila is the second most common cause of admission to ICU, not far behind pneumococcal pneumonia. The mortality of severe Legionella pneumonia is high (30%). We report two cases of severe respiratory failure due to Legionella pneumophila type 1 treated with non-invasive ventilation in the Respiratory Intermediate Care Unit of a Department of Respiratory Medicine with good outcomes. Severe community-acquired pneumonia is the most common cause of ARDS, and it is the primary reason for Intensive Care Unit admission with invasive mechanical ventilation. Delay in ICU admission is probably associated with a poorer outcome. The use of non-invasive ventilation in severe community acquired pneumonia is controversial. However, after recent pandemics, the number of studies reporting good rates of success for NIV has increased. Both our patients were managed in a respiratory intermediate care unit, avoiding invasive ventilation and invasive monitoring, which lowered costs yet was equally effective in providing a good outcome when compared to intubation in the Intensive Care Unit.
