Infections during AML induction chemotherapy in a contemporary cohort without fluoroquinolone prophylaxis.
Article in Infection, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeRecent advances in the treatment of acute myeloid leukemia (AML) and optimized supportive care have improved survival outcomes. However, infections during remission induction chemotherapy remain a leading cause of morbidity and mortality. While antifungal prophylaxis is standard, the role of routine antibacterial prophylaxis is increasingly debated due to adverse effects and resistance. This study aimed to characterize infectious complications in a real-world AML cohort receiving induction chemotherapy without routine antibacterial prophylaxis.
methodsWe retrospectively analyzed 103 adults with newly diagnosed AML who underwent intensive induction therapy at LMU University Hospital between January 2019 and December 2022. All patients received antifungal prophylaxis whereas antibacterial fluoroquinolone (FQ) prophylaxis was not administered. We assessed febrile episodes, clinically and microbiologically documented infections, ICU/IMC admissions, and 30-/90-day mortality.
resultsFebrile episodes occurred in almost all patients. Clinically documented infections accounted for 29.8% and microbiologically confirmed infections for 22.9% of febrile events. Bacteraemia was evenly distributed between Gram-positive and Gram-negative pathogens; multidrug resistance was rare. Proven or probable invasive fungal infections occurred in 6.8% of patients. In 47.2% of cases, the cause of fever remained unknown. Infection-related 30-day mortality was 4.9%. Factors associated with increased 30-day mortality included age ≥ 65 years, ECOG ≥ 2, secondary AML, and ICU/IMC admission for infection.
conclusionInfections remain a major challenge during AML induction therapy. Our findings suggest that FQ prophylaxis should be reevaluated in this setting, focussing on a more individualized approach. In addition, novel diagnostic tools are urgently needed to enable earlier and more targeted infection management in this high-risk population.
