Abstract We argue that the COVID-19 pandemic will result in increased antimicrobial resistance (AMR). Broad-spectrum antibiotic use is common among hospitalized COVID-19 patients and in excess of reported secondary infection rates, suggesting unnecessary prescribing. Selection pressure is likely to be particularly intense in COVID-19 epicentres and within non-epicentre hospital units dedicated to COVID-19 care. Risk factors that increase the likelihood of hospitalization or poor outcomes among COVID-19 patients, such as advanced age, nursing home residence, debilitation, diabetes and cardiopulmonary or other underlying systemic diseases, also predispose to AMR infections. Worry for AMR emergence is heightened since first-wave COVID-19 epicentres were also AMR epicentres. Disruptive direct and indirect effects of COVID-19 globally on economic systems, governance and public health expenditure and infrastructure may fuel AMR spread. We anticipate that the impact of COVID-19 on AMR will vary between epicentres and non-epicentres, by geographic region, hospital to hospital within regions and within specific hospital units.

ABSTRACT Salmonella spp. are important food-borne pathogens that are demonstrating increasing antimicrobial resistance rates in isolates obtained from food animals and humans. In this study, 10 multidrug-resistant, cephalosporin-resistant Salmonellaisolates from bovine, porcine, and human sources from a single geographic region were identified. All isolates demonstrated resistance to cephamycins and extended-spectrum cephalosporins as well as tetracycline, chloramphenicol, streptomycin, and sulfisoxazole. Molecular epidemiological analyses revealed eight distinct chromosomal DNA patterns, suggesting that clonal spread could not entirely explain the distribution of this antimicrobial resistance phenotype. However, all isolates encoded an AmpC-like β-lactamase, CMY-2. Eight isolates contained a large nonconjugative plasmid that could transformEscherichia coli. Transformants coexpressed cephalosporin, tetracycline, chloramphenicol, streptomycin, and sulfisoxazole resistances. Plasmid DNA revealed highly related restriction fragments though plasmids appeared to have undergone some evolution over time. Multidrug-resistant, cephalosporin-resistant Salmonellaspp. present significant therapeutic problems in animal and human health care and raise further questions about the association between antimicrobial resistance, antibiotic use in animals, and transfer of multidrug-resistant Salmonella spp. between animals and man.

The Impact

Sepsis is a frequent complication in immunosuppressed cancer patients and hematopoietic stem cell transplant recipients that is associated with high morbidity and mortality rates. The worldwide emergence of antimicrobial resistance is of special concern in this population because any delay in starting adequate empirical antibiotic therapy can lead to poor outcomes. In this review, we aim to address: (1) the mechanisms involved in the development of sepsis and septic shock in these patients; (2) the risk factors associated with a worse prognosis; (3) the impact of adequate initial empirical antibiotic therapy given the current era of widespread antimicrobial resistance; and (4) the optimal management of sepsis, including adequate and early source control of infection, optimized antibiotic use based on the pharmacokinetic and pharmacodynamics changes in these patients, and the role of the new available antibiotics.

Objectives Inappropriate antibiotic use contributes to antimicrobial resistance. The SpectrumTM app provides antibiotic decision support, based on local antimicrobial resistance rates. We determined the impact of regional implementation of the app on inpatient antimicrobial appropriateness, inpatient antimicrobial usage (AMU), population-based Clostridioides difficile infection (CDI) rates and cost, using a retrospective, before and after quasi-experimental design, including a one-year study period. Methods The SpectrumTM app was released to prescribers in February, 2019. We performed two one-day inpatient point prevalence surveys using the National Antimicrobial Prescribing Survey tool, six months before (June 25, 2018) and six months after (June 25, 2019) app dissemination. Inpatient AMU in Defined Daily Dose/1000 patient days and CDI incidence were compared, before and after app dissemination. Results The pre-survey included 184 prescriptions, and the post-survey included 197 prescriptions. Appropriateness was 97/176 (55.1%) pre, and 126/192 (65.6%) post (+10.5%, p = 0.051). Inpatient AMU declined by 6.6 DDD/1000 patient days per month, and CDI declined by 0.3 cases per month. Cost savings associated with reduced AMU were $403.98/bed/year and associated with reduced CDI were $82,078/year. Conclusion We observed improvement in antimicrobial stewardship indicators following SpectrumTM implementation. We cannot determine the cause of these improvements.

AbstractAntimicrobial resistance in bacteria causes significant morbidity worldwide. The development and acquisition of resistance to antibiotics is believed to primarily develop under the selective pressure of widespread antibiotic use in humans, however antimicrobial usage in livestock has been proposed as additional, if not principal, driver of antibiotic resistance. In this work, we correlate recent data from the European Union on antibiotic resistance rates with data on antibiotic usage in the primary care and hospital sector and data on veterinary antimicrobial consumption across the individual member states. We quantify the strength of these different potential drivers of antimicrobial resistance in order to compare their biological importance. We found that the correlation between antibiotic use in the hospital sector and antibiotic resistance rates is significantly higher than the correlation between resistance rates and any of the other two predictors. This suggests increased antibiotic use in hospitals as the main driver of the development of antibiotic resistances and necessitates further research on and a re-evaluation of the risks associated with antibiotic use in human and veterinary medicine.

Inappropriate use of antibiotics may lead to antimicrobial resistance. In 2012, Dr. Soetomo Hospital conducted training for pediatric residents on the proper use of antibiotics to limit antimicrobial resistance.Objective To evaluate the impact of a rational, antibiotic-use training program for pediatric residents on their antibiotic prescriptions for patients with typhoid fever.Methods A cross-sectional, analytic study was conducted. We collected data from children with typhoid fever who were hospitalized in Dr. Soetomo Hospital, pre- and post-training on antibiotic prescriptions. Children with other known bacterial infections or who were discharged on request were excluded. Antibiotic prescriptions were evaluated using Gyssens algorithm based on the local protocol. Chi-square test was used to compare the quality of antibiotic prescriptions, before (year 2012) and after (year 2013) the training.Results Forty-nine patients with 67 prescriptions in 2012 and 34 patients with 48 prescriptions in 2013 fulfilled the inclusion criteria. Patients’ ages ranged from 1-18 years. Diagnoses of uncomplicated and complicated typhoid were found in 74% and 26% of subjects, respectively. First line (chloramphenicol, thiamphenicol, ampicillin, trimetroprim and sulfametoxazol) and second line (ceftriaxone and cefixime) use were 72% and 28%, respectively. All patients were discharged in good condition. Appropriate use of antibiotics was noted in 61% of subjects in 2012 and in 81% of subjects in 2013 (P=0.036). The most common type of error in 2012 and 2013 was dosage imprecision (25% and 17%, respectively).Conclusion Training on appropriate use of antibiotics significantly improved the quality of antibiotics prescribed in children with typhoid fever in Dr. Soetomo Hospital.

The Impact

AbstractThe ecological and human health impact of antibiotic use and the related antimicrobial resistance (AMR) in animal husbandry is poorly understood. In many countries, there has been considerable pressure to reduce overall antibiotic use in agriculture or to cease or minimise use of human critical antibiotics. However, a more nuanced approach would consider the differential impact of use of different antibiotic classes; for example, it is not known whether reduced use of bacteriostatic or bacteriolytic classes of antibiotics would be of greater value. We have developed an ordinary differential equation model to investigate the effects of farm practice on the spread and persistence of AMR in the dairy slurry tank environment. We model the chemical fate of bacteriolytic and bacteriostatic antibiotics within the slurry and their effect on a population of bacteria, which are capable of resistance to both types of antibiotic. Through our analysis, we find that changing the rate at which a slurry tank is emptied may delay the proliferation of multidrug-resistant bacteria by up to five years depending on conditions. This finding has implications for farming practice and the policies that influence waste management practices. We also find that, within our model, the development of multidrug resistance is particularly sensitive to the use of bacteriolytic antibiotics, rather than bacteriostatic antibiotics, and this may be cause for controlling the usage of bacteriolytic antibiotics in agriculture.

Abstract Background Morbidity from urinary tract infection (UTI) is high. Urine culture is the reference method for UTI diagnosis. Its diagnostic yield is limited as prior antibiotic use prevents growth of established uropathogens, many emerging uropathogens do not grow under routine culture conditions, and results interpretation can be subjective. Faster, more comprehensive diagnostics could help manage recurrent and/or drug-resistant infections. We evaluated the diagnostic yield of a precision metagenomic (PM) workflow for pathogen detection & antimicrobial resistance (AMR) characterization directly from urine. Methods Residual urine samples from symptomatic adults evaluated by culture & susceptibility were identified by a combination of consecutive & stratified random sampling (n=480; 79% culture positive). DNA was extracted with modifications to the Quick-DNA Urine Kit (Zymo). Libraries were generated with Illumina DNA Prep with Enrichment for clinically relevant targets (191 pathogens, 1976 AMR markers) with the Explify Urinary ID/AMR Panel (UPIP, IDbyDNA). Enriched libraries were sequenced on the NextSeq550 (Illumina) and data analyzed with the Explify UPIP Data Analysis Solution (IDbyDNA). Results For bacterial uropathogens, 94% positive agreement was observed between this PM workflow and culture. PM detected fastidious and/or anaerobic potential uropathogens in 30% and 7% of samples reported as culture-negative or positive for other bacteria, respectively. Total agreement between AMR marker detection and phenotypic resistance was 78%. Notably, PM predicted phenotypes of ESBL E. coli and K. pneumoniae (10/10), MRSA (9/9), and vancomycin-resistant E. faecium (4/5). PM also detected pathogens associated with sexually-transmitted infection (C. trachomatis, HSV) and bacterial vaginosis (G. vaginalis). PM produced complete results within 24-36 hours of sample receipt (vs culture & susceptibility: 42-72 hrs). Conclusion The sensitivity of PM for uropathogen detection was noninferior to culture (Δ = 0.05; Nam RMLE; p < 0.0005). PM predicted antimicrobial resistance phenotypes for common uropathogens and identified potential pathogens not detected by conventional culture. Future studies should assess the impact of PM-guided management on clinical outcomes. Disclosures Rita C.

The Impact

This review of pediatric antibiotic stewardship programs (ASPs) summarized the antibiotic prescribing interventions and their impact on antibiotic use and antimicrobial resistance. We reviewed studies of pediatric ASP, including the search terms “antimicrobial stewardship,” “antibiotic stewardship,” “children,” and “pediatric.” The articles’ selection and review were performed independently by 2 investigators, according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Twenty-one studies were included, from the past 15 years, increasing after the 2007 IDSA (Infectious Diseases Society of America) guidelines for ASP with a large variability of the programs, and the virtual exclusive focus on inpatient settings (90%): 16 formalized ASP and 5 non-ASP actions. A reduction in antibiotic prescribing in ASP has been demonstrated in the studies reporting pediatric ASP, but only one ASP showed a significant impact on antimicrobial resistance. However, the impact on antibiotic consumption in pediatrics demonstrated the important contribution of these strategies to improve antibiotic use in children, without complications or negative issues.

ABSTRACTIn this study, we aimed to evaluate the relationship between the rates of resistance ofPseudomonas aeruginosato carbapenems and the levels and diversity of antibiotic consumption. Data were retrospectively collected from 20 acute care hospitals across 3 regions of Switzerland between 2006 and 2010. The main outcome of the present study was the rate of resistance to carbapenems amongP. aeruginosa. Putative predictors included the total antibiotic consumption and carbapenem consumption in defined daily doses per 100 bed days, the proportion of very broad-spectrum antibiotics used, and the Peterson index. The present study confirmed a correlation between carbapenem use and carbapenem resistance rates at the hospital and regional levels. The impact of diversifying the range of antibiotics used againstP. aeruginosaresistance was suggested by (i) a positive correlation in multivariate analysis between the above-mentioned resistance and the proportion of consumed antibiotics having a very broad spectrum of activity (coefficient = 1.77; 95% confidence interval, 0.58 to 2.96;P< 0.01) and (ii) a negative correlation between the resistance and diversity of antibiotic use as measured by the Peterson homogeneity index (coefficient = −0.52;P< 0.05). We conclude that promoting heterogeneity plus parsimony in the use of antibiotics appears to be a valuable strategy for minimizing the spread of carbapenem resistance inP. aeruginosain hospitals.
