hematologic patients

Objective. To use algorithm of microbiologic and epidemiologic methods when detecting two or more cases of legionellosis in the medical institution, in accordance with the international guidelines and to assess its efficacy. Materials and Methods. A total of 76 hematological patients with pneumonia and acute respiratory failure were tested for legionellosis using bronchoalveolar lavage (BAL) fluid culture and Legionella urinary antigen test between December 2010 and January 2013. Water samples obtained from the institution’s hot water supply system were tested for Legionella by the standard microbiology method.

Objective. To determine significance of Legionella pneumonia for hematological patients in ICUs, and to evaluate prospects of the proposed algorithm for diagnosis of legionellosis. Materials and Methods. A total of 37 hematological ICU patients were assessed for legionellosis between December 2010 and February 2012. Bronchoalveolar lavage (BAL) fluid culture and Legionella urinary antigen test (rapid immunochromatographic assay) were used to diagnose legionellosis. Results. Diagnosis of legionellosis was confirmed in 4 (11%) patients, of which 3 had fatal outcome.
