Abstract:
We present the case of a community-acquired pneumonia by Legionella Pneumophila in a 31-year-old patient with Crohn's disease under anti-TNF agents. Following this and other similar cases reported in literature, we propose to include recommendations to prevent this infection in patients starting treatment with immunosuppressant drugs through simple measures regarding the control of water in the patients' home.
