Discussion
Immunocompromised patients, especially those receiving cytotoxic
chemotherapy are at higher risk for developing Legionella pneumonia
(10). Our case showed that delay in diagnosis verification led to
worsened patient’s condition due to respiratory failure. Only after
pathogen verification in the urine, appropriate therapy was prescribed.
We believe that in the treatment of patients with immunodeficiency and
signs of pneumonia, it is imperative to actively use the available
methods of express diagnosis of Legionella pneumophila. That can reduce
the mortality rate to 0-5.5%. This case shows that the diagnosis is
very important, but also with an unusual clinical manifestation of
pneumonia, legionella should be considered in the differential diagnosis
in immunocompromised patients.
