Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a prospective, observational cohort study to assess the frequency with which neutropenic patients with hematologic malignancies and hematopoietic cell transplant (HCT) recipients are colonized with fluoroquinolone-resistant Enterobacterales (FQRE) and the clinical impact of FQRE colonization.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a prospective, observational cohort study to assess the frequency with which neutropenic patients with hematologic malignancies and hematopoietic cell transplant (HCT) recipients are colonized with fluoroquinolone-resistant Enterobacterales (FQRE) and the clinical impact of FQRE colonization.

The investigator will collect perianal swabs from patients receiving induction chemotherapy for acute leukemia or undergoing hematopoietic stem cell transplantation (HCT), and who are receiving fluoroquinolone (FQ) prophylaxis. FQRE colonization will be assessed by culture, and the investigator will correlate FQRE colonization with the risk of Gram-negative bacteremia during neutropenia.

Population: 410 adults with acute leukemia who are receiving induction chemotherapy and HCT recipients who are receiving FQ prophylaxis during neutropenia.

Results of this study will be combined with a portion of subject data from an identically-designed R01-funded study of FQRE colonization. The combined data will be used for study analysis and reporting.
