Abstract
Background: Hospital-acquired infection with carbapenem-resistant Enterobacteriaceae (CRE) is a global concern. The administration of antibiotics among the infected and non-infected immunocompromised children with SARS-CoV-2 is associated with an increased risk of intestinal CRE colonization and bacteremia during hospitalization. Objectives: The present study aimed to detect the correlation between the intestinal colonization of carbapenemase encoding Enterobacteriaceae with SARS-CoV-2 infection and antibiotic prescription among immunocompromised children admitted to the oncology and Bone Marrow Transplantation (BMT) wards. Methods: Stool samples were collected from the immunocompromised children, and the members of Enterobacteriaceae were isolated using standard microbiological laboratory methods. Carbapenem resistance isolates were initially characterized by the disc diffusion method according to CLSI 2021 and further confirmed by the PCR assay. SARS-CoV-2 infection was also recorded according to documented real-time PCR results. Results: In this study, 102 Enterobacteriaceae isolates were collected from the stool samples. The isolates were from Escherichia spp. (59/102, 57.8%), Klebsiella spp. (34/102, 33.3%), Enterobacter spp. (5/102, 4.9%), Citrobacter spp. (2/102, 1.9%), and Serratia spp. (2/102, 1.9%). The carbapenem resistance phenotype was detected among 42.37%, 73.52%, 40%, 50%, and 100% of Escherichia spp., Klebsiella spp., Enterobacter spp., Citrobacter spp., and Serratia spp., respectively. Moreover, blaOXA-48 (49.1%) and blaNDM-1 (29.4%), as well as blaVIM (19.6%) and blaKPC (17.6%) were common in the CRE isolates. SARS-CoV-2 infection was detected in 50% of the participants; however, it was confirmed in 65.45% (36/55) of the intestinal CRE carriers. The administration of antibiotics, mainly broad-spectrum antibiotics, had a significant correlation with the CRE colonization in both the infected and non-infected children with SARS-CoV-2 infection. Conclusions: Regardless of the COVID-19 status, prolonged hospitalization and antibiotic prescription are major risk factors associated with the CRE intestinal colonization in immunocompromised children.

[PMID: 37256160 PMCID: PMC10226056 DOI: 10.1177/17571774211066762] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2020] [Accepted: 11/17/2021] [Indexed: 09/20/2023] Open
Abstract
Background Antimicrobial resistance is exponentially worsening, and the spread of prevalent carbapenem resistant Enterobacteriaceae (CRE) is a major contributor to this global concern. Infection prevention and control strategies are increasingly consolidated key tools to control this worldwide problem. Aim To identify, collect and analyse available evidence regarding the impact of infection prevention and control strategies on prevalent CRE dissemination. Methods Pubmed®, Scopus® and Web of Science® were searched systematically for articles published between 1th January 2017 and 30th June 2020, guided by the research question 'What are the most effective and efficient strategies to prevent and control infection/colonisation caused by Carbapenem resistant Escherichia coli and Carbapenem resistant Klebsiella pneumoniae?'. Findings Eleven thousand six hundred and thirty-five publications were found, but after applying the inclusion and exclusion criteria, only 30 were selected. The majority of reviewed studies (n = 24) were performed in outbreak situations, 26 studies occurred in acute care units and of those, 17 in intensive care units . From the set of implemented infection prevention and control measures, in 29 studies surveillance cultures were applied, in 23 studies patients were isolated or cohorted and, in general, all described the implementation of standard and contact precaution measures. Conclusion This systematic review underlines the importance of infection prevention and control strategies in CRE dissemination, standing out the need of further studies outside outbreak and intensive care units contexts. Investment increments and training and educating of all involved are also important contributors to shift this problem, but still with relevant gaps in their implementation, in all types of care units, that need to be addressed.

Outbreak of New Delhi Metallo-Beta-lactamase Carbapenemase Producing Enterobacterales on a bone marrow transplant unit: Role of the environment. Infect Prev Pract 2021; 3:100125. [PMID: 34368742 PMCID: PMC8336029 DOI: 10.1016/j.infpip.2021.100125] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2020] [Accepted: 02/03/2021] [Indexed: 11/24/2022] Open
Abstract
BACKGROUND Carbapenemase Producing Enterobacterales (CPE) are a global health concern. Nosocomial outbreaks have been reported globally with patient-to-patient transmission felt to be the most frequent route of cross-transmission. AIM To describe the investigation and control of an outbreak of healthcare-associated New Delhi Metallo-beta-lactamase (NDM) CPE on a haematology ward, over 2 months. METHODS Four patients acquired CPE; all had gastrointestinal tract colonisation with two subsequently developing bacteraemias. The outbreak team performed a retrospective review, prospective case finding and environmental sampling using swabs, settle plates, air and water sampling. Immediate control measures were implemented including appropriate isolation of cases and additional ward cleaning with chlorine disinfectant, ultra-violet light decontamination and hydrogen peroxide. FINDINGS Following two cases of nosocomial acquired CPE prospective case finding identified two further cases. 4.6% of the initial environmental samples were positive for CPE including from waste water sites, the ward sluice and the ward kitchen. Three of the four CPE isolates were identical on pulse field gel electrophoresis (PFGE) typing. Detection of the CPE from the ward kitchen environmental samples suggests a possible role for cross transmission. CONCLUSION This is the first CPE outbreak report to highlight the role of a ward kitchen as a possible source of cross-transmission. In view of this we suggest ward kitchens are reviewed and investigated in nosocomial CPE outbreaks.

Abstract
BACKGROUND More evidence is emerging on the role of surface decontamination for reducing hospital-acquired infection (HAI). Timely and adequate removal of environmental pathogens leads to measurable clinical benefit in both routine and outbreak situations. OBJECTIVES This systematic review aimed to evaluate published studies describing the effect of automated technologies delivering hydrogen peroxide (H202) or ultra-violet (UV) light on HAI rates. METHODS A systematic review was performed using relevant search terms. Databases were scanned from January 2005 to March 2020 for studies reporting clinical outcome after use of automated devices on healthcare surfaces. Information collected included device type, overall findings; hospital and ward data; study location, length and size; antimicrobial consumption; domestic monitoring; and infection control interventions. Study sponsorship and duplicate publications were also noted. RESULTS While there are clear benefits from non-touch devices in vitro, we found insufficient objective assessment of patient outcome due to the before-and-after nature of 36 of 43 (84%) studies. Of 43 studies, 20 (47%) used hydrogen peroxide (14 for outbreaks) and 23 (53%) used UV technology (none for outbreaks). The most popular pathogen targeted, either alone or in combination with others, was Clostridium difficile (27 of 43 studies: 63%), followed by methicillin-resistant Staphylococcus aureus (MRSA) (16 of 43: 37%). Many owed funding and/or personnel to industry sponsorship (28 of 43: 65%) and most were confounded by concurrent infection control, antimicrobial stewardship and/or cleaning audit initiatives. Few contained data on device costs and rarely on comparable costs (1 of 43: 2%). There were expected relationships between the country hosting the study and location of device companies. None mentioned the potential for environmental damage, including effects on microbial survivors. CONCLUSION There were mixed results for patient benefit from this review of automated devices using H202 or UV for surface decontamination. Most non-outbreak studies lacked an appropriate control group and were potentially compromised by industry sponsorship. Concern over HAI encourages delivery of powerful disinfectants for eliminating pathogens without appreciating toxicity or cost benefit. Routine use of these devices requires justification from standardized and controlled studies to understand how best to manage contaminated healthcare environments.

Hilliquin D, Lomont A, Zahar JR. Cohorting for preventing the nosocomial spread of Carbapenemase-Producing Enterobacterales, in non-epidemic settings: is it mandatory? J Hosp Infect 2020; 105:S0195-6701(20)30197-3. [PMID: 32315668 DOI: 10.1016/j.jhin.2020.04.022] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2020] [Accepted: 04/14/2020] [Indexed: 12/26/2022]
Abstract
BACKGROUND Worldwide dissemination of Carbapenemase-Producing Enterobacterales (CPE) has led to national and international guidance recommending the implementation of cohorting in healthcare settings (HS). However, in view of recent data regarding the spread of Extended-spectrum Beta-lactamase-producing Enterobacterales, we may wonder about the usefulness of this measure in a non-outbreak settings; here, individual contact isolation may be sufficient to control the risk of dissemination. AIM/METHODS We conducted a narrative review of the literature and discussed the role of cohorting. FINDINGS CPE are responsible for outbreaks in HS, which are considered the epicentre of spread of resistance strains. CPE are responsible for adverse effects such as increases in hospital stay and costs, less therapeutic options and thus higher risk of clinical failures and mortality. Environment and materials have also been described contaminated with CPE and can be the source of outbreak. Even if guidelines and publications have supported implementation of cohorting, there are no randomized studies demonstrating the mandatory nature of this measure. Most studies are descriptive and cohorting is usually one of several other measures to control outbreaks. Cohorting is not adapted to all HS, which requires human and material resources. Other measures must be strengthened such as compliance of hand hygiene, antibiotic stewardship and surveillance of contact patients. Individual risk factors of acquisition should also be evaluated. CONCLUSION Local epidemiology and resources must be assessed before implementing cohorting.

Tracking KPC-3-producing ST-258 Klebsiella pneumoniae outbreak in a third-level hospital in Granada (Andalusia, Spain) by risk factors and molecular characteristics. Mol Biol Rep 2019; 47:1089-1097. [PMID: 31792747 DOI: 10.1007/s11033-019-05203-w] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2019] [Accepted: 11/21/2019] [Indexed: 12/26/2022]
Abstract
The objective of this study was to determine clinical-epidemiological characteristics of the patients and the genetic characteristics of carbapenemase KPC-3-producing Klebsiella pneumoniae isolates belonging to sequence type ST258. The eligible study population was all patients with isolates detected between October 2015 and March 2017. Clinical-epidemiological and microbiological data were gathered on risk factors associated with infection by this clone. Antimicrobial susceptibility was determined using MicroScan system and diffusion in agar. Genes encoding carbapenemases were detected using PCR and Sanger sequencing. The sequence type was assigned by MLST, and the genetic relationship among clinical isolates was determined by pulsed field electrophoresis and by analysis of the genetic environment. The study included 23 individuals with isolates of KPC-3/ST258; the mean age was 77 year, and mean stay pre-isolation was 32 days; 81% received empirical antimicrobial treatment. Isolates were only susceptible to gentamicin (CIM ≤ 2 mg/L), tigecycline (CIM ≤ 1 mg/L), and colistin (CIM ≤ 2 mg/L). The isolates belonged to ST258, with five pulse types or subgroups. All isolates showed amplification of KPC, which was identified as KPC-3 variant. Gene blaKPC-3 was flanked by insertion sequences Kpn6 and Kpn7 within Tn4401 transposon isoform a. We report, for the first time in Spain, an 18-month outbreak by KPC-3-producing ST258 K. pneumoniae. Its acquisition was associated with a history of antimicrobial therapy, with three treatment options, and with high mortality. The detection of different pulse types is attributable to different introductions of the clone in our setting, supporting the need for multi-resistant isolate surveillance studies.
