Clinical outcomes of patients hospitalized in internal medicine wards adequately treated for bloodstream infections caused by NDM-producing Klebsiella pneumoniae. Results from a real-life retrospective multi-center study in an endemic area.
Article in Infection, 2025. 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 6 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
backgroundNew Delhi metallo-beta-lactamase (NDM)-producing Klebsiella pneumoniae (NDM-Kp) represents a growing challenge for modern medicine.
objectivesTo assess real-life clinical outcomes in patients adequately treated in Internal medicine units (IMUs) for bloodstream infections (BSI) caused by NDM-Kp.
methodsA two-years retrospective study was conducted recruiting 30 consecutive adult patients with NDM-Kp BSI treated with an adequate definitive antibiotic therapy (27 aztreonam plus ceftazidime/avibactam; 3 cefiderocol) in three Italian IMUs located in a highly endemic area.
resultsMean age of patients was 75.3 years, mean Charlson Comorbidity Index (CCI) 7.5. All the patients had rectal colonization. Thirty-day mortality rate was 46.7%; 78.6% of patients who died received an adequate empiric therapy. Non-survivors had mean age, CCI and SOFA score significantly higher compared to survivors (80.1 vs. 71.2, p = 0.036; 8.6 vs. 6.6, p = 0.047; 5.9 vs. 4, p = 0.043, respectively). The percentage of survivors was significantly higher among the 13 cases with community-acquired than in the 17 with hospital-acquired BSI (76.9% vs. 35.3%, p = 0.024). In the multivariate penalized logistic regression analysis, age, CCI, SOFA score and hospital-acquired BSI onset were identified as independent predictors of mortality.
conclusionThis study provides real-life data on clinical outcomes regarding old and highly multimorbid patients hospitalized in IMU for BSI caused by NDM-Kp, showing a very high 30-day mortality even in case of adequate treatment.
