Abstract
Background and Objectives: There is a need for information regarding the clinical picture of hemorrhagic pneumonia caused by Stenotrophomonas maltophilia in patients with hematologic malignancies. In this study, we aimed to investigate the risk factors associated with hemorrhagic pneumonia caused by Stenotrophomonas maltophilia. Materials and Methods: A review of the clinical picture of hemorrhagic pneumonia based on reported cases in the literature was performed. In addition, patients with hematologic malignancies who had a Stenotrophomonas maltophilia infection were included in the meta-analysis to evaluate risk factors for hemorrhagic pneumonia. Results: A total of 91 patients had hemorrhagic pneumonia. Acute myeloid leukemia was present in 57 patients (62.6%). Those with bacteremia accounted for 94%, while those with neutropenia accounted for 95% and those with thrombocytopenia accounted for 86.7%. Hemorrhagic pneumonia was a risk factor for mortality of Stenotrophomonas maltophilia infection in patients with hematologic malignancies. Neutropenia and thrombocytopenia were identified as risk factors for hemorrhagic pneumonia. Conclusions: Stenotrophomonas maltophilia bacteremia with hemorrhagic pneumonia in patients with hematologic malignancies is a situation with rapid development and high mortality. Neutropenia and thrombocytopenia were risk factors for hemorrhagic pneumonia in patients with hematologic malignancies and with Stenotrophomonas maltophilia bacteremia; thus, these patients should be managed with caution.
