Abstract
This retrospective study aims to describe the etiology and resistance patterns of pathogens causing bacteremia in children with solid tumors in a tertiary pediatric hematology-oncology center in Jerusalem, Israel (2011-2019). Factors associated with multidrug-resistant (MDR) bacteremia and mortality were analyzed. A total of 228 pathogens were isolated in 126 patients; 61.0% were gram-negative rods (GNR) and 38.2% were gram-positive cocci (GPC). The most common pathogens were Klebsiella pneumoniae (19.3%), Escherichia coli (17.5%), and coagulase-negative staphylococci (16.2%). The proportion of MDR-GNR was 18.2%, while the proportion of MDR-GPC was 55.2%. In logistic regression analysis, breakthrough bacteremia on a penicillin-group antibiotic (odds ratio [OR] 5.69, [95% confidence interval 1.42-22.76], p-value = 0.014) was associated and underlying diagnosis of neuroblastoma was inversely associated (OR 0.17, [0.04-0.81], p-value = 0.026) with MDR-GNR bacteremia; while the previous hospitalizations' duration (OR 1.032/day, [1.01-1.06], p-value = 0.007) and oncologic treatment intensity (OR 2.19, [1.08-4.45, p-value = 0.03) were associated with MDR-GPC bacteremia. Shock, prolonged profound neutropenia, and pediatric intensive care unit (PICU) admission were associated with 7-day mortality; and relapsed disease, oncologic treatment intensity, prolonged profound neutropenia, and PICU admission-with 30-day mortality in the univariate analyses. Empirical antibiotic choice should be based on factors associated with MDR infections in this specific population.

J Pediatr Hematol Oncol 2022; 44:e160-e167. [PMID: 34310474 DOI: 10.1097/mph.0000000000002258] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/02/2020] [Accepted: 05/30/2021] [Indexed: 11/26/2022]
Abstract
Bloodstream infections (BSIs) adversely affect clinical outcome in children with cancer. Over 1 decade, this retrospective cohort study describes pathogen distribution in BSIs and antimicrobial susceptibility against empirical antibiotics frequently prescribed in children with cancer. The antibiotic efficacy was evaluated through the determination of minimal inhibitory concentrations for piperacillin-tazobactam and meropenem and by disk diffusion for remaining antibiotics. From 2004 to 2013, 398 BSIs occurred in 196 children with cancer (median age: 5.4 y), resulting in 457 bacteria. Overall, 266 (58.2%) were Gram-positive, and 191 (41.8%) were Gram-negative with a significant Gram-positive increase over time (P=0.032). Coagulase-negative staphylococci (74, 16.2%), viridans group streptococci (67, 14.7%), Escherichia coli (52, 11.4%), and Staphylococcus aureus (39, 8.5%) were the most common pathogens. Susceptibility to piperacillin-tazobactam (95.9%, P=0.419) and meropenem (98.9%, P=0.752) was stable over time, and resistance was observed among viridans group streptococci against piperacillin-tazobactam (18%) and meropenem (7%) and among Enterobacterales against piperacillin-tazobactam (3%). Vancomycin showed 98% Gram-positive activity, gentamicin 82% Gram-negative activity and ampicillin, cefotaxime, and cefuroxime were active in 50%, 72%, and 69% of pathogens, respectively, and BSI-related mortality was 0%. In conclusion, over 1 decade, we report an increase in Gram-positive BSIs, and stable, low-resistance rates against currently recommended empirical antibiotics, piperacillin-tazobactam and meropenem.

Abstract
OBJECTIVE To investigate the application value of metagenomic next-generation sequencing (mNGS) in children with hematological diseases presenting with Febrile Neutropenic (FN). METHODS We retrospectively analyzed the clinical data of 49 hematological children with FN, and compared the results of mNGS with those of traditional pathogen detection (TPD) and the prognoses of mNGS positive group and negative group. RESULTS A total of 77 pathogenic strains were identified, of which 70 strains were detected by mNGS, 19 strains by TPD , and Aspergillus and G- bacterias were the predominant strains in FN children who developed bloodstream infections. 42 cases were in the mNGS-positive group, of which 17 were simple infections, 25 were mixed infections, and 7 were in the negative group; the TPD-positive group contained 19 cases, all of which were simple infections. The detection rate of total and mixed pathogens was higher than that of TPD, and the difference was statistically significant (P<0.05). mNGS positive group was detected earlier than the negative group, and with lower mortality and drug-related adverse events (DRAE) , and the difference was statistically significant (P<0.05). CONCLUSION For FN children with hematological diseases, early mNGS can effectively improve the efficacy of pathogen detection, and precise treatment after clarifying the pathogens can reduce mortality and avoid antibiotic abuse.

Bloodstream infections in adult patients with malignancy, epidemiology, microbiology, and risk factors associated with mortality and multi-drug resistance. BMC Infect Dis 2021; 21:636.

Abstract
Background This study aimed to investigate the epidemiology, microbiology, and risk factors associated with mortality and multi-drug resistance bacterial bloodstream infections (BSIs) among adult cancer patients in Shiraz, Iran. We also report a four-year trend of antimicrobial resistance patterns of BSIs. Methods We conducted a retrospective study at a referral oncology hospital from July 2015 to August 2019, which included all adults with confirmed BSI. Results 2393 blood cultures tested during the four-year study period; 414 positive cultures were included. The mean age of our patients was 47.57 ± 17.46 years old. Central Line-Associated BSI (CLABSI) was more common in solid tumors than patients with hematological malignancies. Gram-negative (GN) bacteria were more detected (63.3%, 262) than gram-positive bacteria (36.7%, 152). Escherichia coli was the most common gram-negative organism (123/262, 47%), followed by Pseudomonas spp. (82/262, 31%) and Klebsiella pneumoniae (38/262, 14.5%). Coagulase-negative staphylococci (CoNS) was the most frequently isolated pathogen among gram-positive bacteria (83/152, 54.6%). Acinetobacter spp., Pseudomonas spp., E. coli, and K. pneumoniae were the most common Extended-Spectrum Beta-Lactamase (ESBL) producers (100, 96.2, 66.7%, and 60.7, respectively). Acinetobacter spp., Pseudomonas spp., Enterobacter spp., E. coli, and K. pneumoniae were the most common carbapenem-resistant (CR) isolates (77.8, 70.7, 33.3, 24.4, and 13.2%, respectively). Out of 257 Enterobacterales and non-fermenter gram-negative BSIs, 39.3% (101/257) were carbapenem-resistant. Although the incidence of multi-drug resistance (MDR) gram-negative BSI increased annually during 2015–2018, the mortality rate of gram-negative BSI remains unchanged at about 20% (p-value = 0.55); however, the mortality rate was significantly greater (35.4%) in those with resistant gram-positive BSI (p-value = 0.001). The overall mortality rate was 21.5%. Early (7-day mortality) and late mortality rate (30-day mortality) were 10 and 3.4%, respectively. Conclusions The emergence of MDR gram-negative BSI is a significant healthcare problem in oncology centers. The high proportion of the most frequently isolated pathogens were CR and ESBL-producing Enterobacterales and Pseudomonas spp. We have few effective choices against MDRGN BSI, especially in high-risk cancer patients, which necessitate newer treatment options.

The Pattern of Microorganisms and Drug Susceptibility in Pediatric Oncologic Patients with Febrile Neutropenia. J Pathog 2021; 2021:6692827. [PMID: 33854800 PMCID: PMC8021465 DOI: 10.1155/2021/6692827] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2020] [Accepted: 03/18/2021] [Indexed: 11/18/2022] Open
Abstract
Objective The study aimed to describe the pattern of causative microorganisms, drug susceptibility, risk factors of antibiotic-resistant bacterial infection, and clinical impact of these organisms on pediatric oncology patients with febrile neutropenia. Methods A retrospective descriptive study of oncologic patients aged less than 15 years who were diagnosed with febrile neutropenia in King Chulalongkorn Memorial Hospital was conducted between January 2013 to December 2017. Characteristics and clinical outcomes of febrile neutropenia episodes, causative pathogens, and their antibiotic susceptibilities were recorded. Result This study included 267 patients with 563 febrile neutropenia episodes. The median (range) age was 5.1 years (1 month-15 years). The most common underlying disease was acute lymphoblastic leukemia (42.7%). Of 563 febrile episodes, there were 192 (34.1%) with microbiologically documented infection. Among these 192 episodes of microbiologically documented infection, there were 214 causative pathogens: 154 bacteria (72%), 32 viruses (15%), 27 fungus (12.6%), and 1 Mycobacterium tuberculosis (0.4%). Gram-negative bacteria (48.6%) accounted for most of the causative pathogens. Twenty-three percent of them were multidrug resistant, and 18% were carbapenem resistant. Among Gram-positive bacterial infection which accounted for 23.4% of all specimens, the proportion of MRSA was 20%. The 2-week mortality rate was 3.7%. Drug-resistant Gram-negative bacterial infection caused significant adverse events and mortality compared to nonresistant bacterial infection (p < 0.05). Conclusion There is high rate of drug-resistant organism infection in pediatric oncology patients in a tertiary-care center in Thailand. Infection with drug-resistant Gram-negative bacterial infection was associated with significant morbidity and mortality. Continuous surveillance for the pattern of drug-resistant infections is crucial.

Abstract
Context Febrile neutropenia is a serious complication of chemotherapy affecting patients with both hematological and solid malignancies, respectively. To the best of our knowledge, there is paucity of literature from Uttarakhand, India on microbiological profile of blood stream infections (BSIs) in febrile neutropenic patients. Aims The study aims to generate preliminary data on microbiological profile and antibiotic resistance pattern of BSIs in febrile neutropenic patients. Settings and Design The design involved cross-sectional study from January 1, 2019 to July 31, 2019. Methods and Materials Data of nonrepetitive paired peripheral blood samples obtained from 306 consecutive febrile neutropenic cancer patients of all age groups and both sexes, for culture and sensitivity testing, were retrospectively analyzed. All blood samples were subjected to aerobic culture using BACT/ALERT three-dimensional microbial detection system. Growth obtained in culture was identified by conventional biochemical methods. Antibiotic susceptibility testing of bacterial isolates was performed using modified Kirby Bauer disk diffusion method. Statistical Analysis Used Fisher's exact test was used for the analysis. Results Mean age ± SD of the study population was 32.39 ± 10.56 years with a male to female ratio of 1.55:1. 74.18% of the blood samples were received from patients suffering from hematological malignancies. Microbiologically confirmed BSIs were observed in 27.1% patients. Gram-negative bacilli were predominantly isolated in culture with Klebsiella spp . being the most common. Percentage resistance values of gram-negative bacilli to aminoglycosides, β-lactam/β-lactamase inhibitor combinations, fluoroquinolones, cephalosporins, carbapenems, chloramphenicol, ampicillin, co-trimoxazole, and doxycycline were 26.6 to 91.7%, 8.3 to 86.6%, 10 to 66.7%, 13.3 to 73.3%, 8.3 to 73.3%, 80 to 93.3%, 13.3 to 20%, 16.7 to 66.6%, and 13.3 to 16.7%, respectively. Conclusion Implementation of antimicrobial stewardship program along with hospital infection control practices is needed for preventing BSIs due to MDR organisms.
