A decade-long, single-center study in a French ICU examined the characteristics and outcomes of 185 consecutive patients admitted with neutropenic sepsis or septic shock between 2012 and 2022.

The analysis revealed a significant shift in the patient population over time: the more recent group (2018–2022) was older and carried a heavier burden of comorbidities compared to the earlier group (2012–2017).

Despite these increasing risk factors, the hospital mortality rate saw a promising, albeit non-statistically significant, decline—dropping from 49.4% to 40.0%.

This suggests that advancements or changes in critical care management may be offsetting the challenges posed by a sicker patient population.

The study identified the lung (24.8%) and the hepatobiliary/gastrointestinal tract (23.8%) as the most common sources of infection, with Gram-negative bacilli being the predominant causative pathogen.

A key finding with implications for clinical practice is the support for initiating combination antibiotic therapy, including an aminoglycoside, immediately upon ICU admission.

This strategy aims to aggressively combat the Gram-negative infections that commonly drive neutropenic sepsis and septic shock, highlighting the need for rapid, broad-spectrum treatment when managing these highly vulnerable patients in the critical care setting.
