Differences in Clinical Outcomes Among Patients With Mold Fungemia

Area of Science:

• Mycology
• Infectious Diseases
• Clinical Medicine

Background:

• Mold bloodstream infections are uncommon but associated with high mortality rates.
• Lomentospora prolificans and Scedosporium species are particularly virulent fungal pathogens.
• Effective management strategies for these infections remain a challenge.

Purpose of the Study:

• To analyze the clinical characteristics and outcomes of mold bloodstream infections.
• To identify risk factors associated with mortality in patients with these infections.
• To underscore the importance of timely diagnosis and treatment.

Main Methods:

• Retrospective analysis of 84 episodes of mold bloodstream infections over a 20-year period.
• Evaluation of patient demographics, clinical data, and treatment outcomes.
• Statistical analysis to identify factors correlating with 30-day mortality.

Main Results:

• The overall 30-day mortality rate was 38%.
• Increased mortality was significantly associated with underlying cancer, intensive care unit (ICU) admission, and healthcare-onset infections.
• Lomentospora prolificans and Scedosporium spp. were identified as key causative agents.

Conclusions:

• Mold bloodstream infections, particularly those caused by Lomentospora prolificans and Scedosporium, carry a substantial mortality risk.
• Prompt identification of high-risk patients (e.g., those with cancer, in the ICU, or with healthcare-onset infections) is crucial.
• Enhanced diagnostic and therapeutic approaches are essential for improving patient outcomes.
