Description

Sidnei Umberto Bertholdi and colleagues compared single-drug against combined treatment for infections caused by Acinetobacter baumannii that resist carbapenem drugs, in a 2026 study from two Brazilian hospitals. This germ resists nearly all standard drugs and haunts intensive care units, causing bloodstream infections and pneumonia in ventilated patients, with very high death rates. Whether adding drugs helps has stayed unsettled.

The study covered 123 patients treated between 2018 and 2022, most in intensive care. Three quarters received combined therapy, usually built around polymyxin antibiotics; sulbactam-based regimens accounted for 16.3 percent of cases, as the authors report. Death rates were nearly the same for both strategies, at 73.3 percent for single-drug and 73.1 percent for combined treatment in the reported figures. In adjusted analysis, only the APACHE II score predicted death. The authors suspect illness severity, not drug strategy, drove the outcomes, and they call for future trials.
