Abstract
This study aims to analyze the risk factors for the development of multidrug-resistant (MDR) and carbapenem-resistant (CR) bacteria bloodstream infection (BSI) in a patient with acute leukemia (AL) and the mortality in gram-negative bacteria (GNB) BSI. This is a retrospective study conducted at West China Hospital of Sichuan University, which included patients diagnosed with AL and concomitant GNB BSI from 2016 to 2021. A total of 206 patients with GNB BSI in AL were included. The 30-day mortality rate for all patients was 26.2%, with rates of 25.8% for those with MDR GNB BSI and 59.1% for those with CR GNB BSI. Univariate and multivariate analyses revealed that exposure to quinolones (Odds ratio (OR) = 3.111, 95% confidence interval (95%CI): 1.623-5.964, p = 0.001) within the preceding 30 days was an independent risk factor for MDR GNB BSI, while placement of urinary catheter (OR = 6.311, 95%CI: 2.478-16.073, p < 0.001) and exposure to cephalosporins (OR = 2.340, 95%CI: 1.090-5.025, p = 0.029) and carbapenems (OR = 2.558, 95%CI: 1.190-5.497, p = 0.016) within the preceding 30 days were independently associated with CR GNB BSI. Additionally, CR GNB BSI (OR = 2.960, 95% CI: 1.016-8.624, p = 0.047), relapsed/refractory AL (OR = 3.035, 95% CI: 1.265-7.354, p = 0.013), septic shock (OR = 5.108, 95% CI: 1.794-14.547, p = 0.002), platelets < 30 × 109/L before BSI (OR = 7.785, 95% CI: 2.055-29.492, p = 0.003), and inappropriate empiric antibiotic therapy (OR = 3.140, 95% CI: 1.171-8.417, p = 0.023) were independent risk factors for 30-day mortality in AL patients with GNB BSI. Prior antibiotic exposure was a significant factor in the occurrence of MDR GNB BSI and CR GNB BSI. CR GNB BSI increased the risk of mortality in AL patients with GNB BSI.

Abstract
BACKGROUND Lung cancer (LC) is the leading cause of cancer death. Patients treated with chemotherapy are at risk of developing chemotherapy-induced febrile neutropenia (FN), a potentially life-threatening complication. The aims of this study were (1) to characterize FN admissions of patients with LC in a pulmonology department, and (2) to determine associations between patient profiles, first-line antibiotic failure (FLAF) and mortality. METHODS Retrospective observational case-series, based on the analysis of medical records of LC patients that required hospitalization due to chemotherapy-induced FN. RESULTS A total of 42 cases of FN were revised, corresponding to 36 patients, of which 86.1% were male, with a mean age of 66.71±9.83 years. Most patients had a performance status (PS) equal or less than 1, and metastatic disease was present in 40.5% (n=17). Respiratory tract infections accounted for 42.9% (n=18) of FN cases, and multidrug-resistant Staphylococcus aureus was the most isolated agent. The mortality rate was 16.7% (n=7), and the FLAF was 26.2% (n=11). Mortality was associated with a PS≥2 (P=0.011), infection by a Gram-negative agent (P=0.001) and severe anemia (P=0.048). FLAF was associated with longer hospitalizations (P=0.020), PS≥2 (P=0.049), respiratory infections (P=0.024), and infection by a Gram-negative (P=0.003) or multidrug-resistant agent (P=0.014). CONCLUSIONS Lower PS, severe anemia, and infections by Gram-negative or multi-resistant agents seem to be associated with worse outcomes in FN patients.

Gram-Negative Bacteria Bloodstream Infections in Patients with Hematological Malignancies - The Impact of Pathogen Type and Patterns of Antibiotic Resistance: A Retrospective Cohort Study. Infect Drug Resist 2021; 14:3115-3124.

Abstract
Background Enterobacteriaceae (EB) and non-fermentative bacteria (NFB) are the main pathogens responsible for gram-negative bloodstream infections (GN-BSI) in patients with hematological malignancies (HMs). These two pathogen types have heterogeneous resistance mechanisms to antibiotics. However, the impact of pathogen species and pattern of antibiotic resistance on the outcomes of patients with HMs remains unclear. Methods We retrospectively collected clinical data of patients with HMs at three comprehensive hospitals in Hunan Province, China, between January 2010 and May 2018. The data analyzed the impact that different species and patterns of antibiotic resistance had on the outcome of patients with HMs. Results The majority of the 835 monomicrobial isolates collected from patients with HMs and GN-BSIs were Enterobacteriaceae (75.7%). While detections of MDR pathogens in BSIs as a whole are decreasing, sub-analysis shows that detections of extended spectrum β-lactamase-producing (ESBL) Enterobacteriaceae and carbapenem-resistant pathogens in BISs are rising. Comparing different species, the early mortality rate associated with infections caused by NFB was significantly higher than infections caused by Enterobacteriaceae (22.6% vs 9.7%, p < 0.001). Across different multidrug-resistant (MDR) patterns, ESBL bacteria did not have a significant impact on health outcomes. Carbapenem-resistant bacteria, on the other hand, were observed to significantly affect early mortality rate, such as carbapenem-resistant Klebsiella pneumoniae (36.0% vs 7.6%, P < 0.001) and carbapenem-resistant non-fermentative bacteria (44.7% vs 16.5%, P < 0.001). Conclusion Our findings suggest that both species and patterns of antibiotic resistance can affect the early mortality of patients with HMs during BSI.
