    Abstract: The Japanese Clinical Practice Guidelines for Management of Sepsis and Septic Shock 2020 (J‐SSCG 2020), a Japanese‐specific set of clinical practice guidelines for sepsis and septic shock created as revised from J‐SSCG 2016 jointly by the Japanese Society of Intensive Care Medicine and the Japanese Association for Acute Medicine, was first released in September 2020 and published in February 2021. An English‐language version of these guidelines was created based on the contents of the original Japanese‐language version. The purpose of this guideline is to assist medical staff in making appropriate decisions to improve the prognosis of patients undergoing treatment for sepsis and septic shock. We aimed to provide high‐quality guidelines that are easy to use and understand for specialists, general clinicians, and multidisciplinary medical professionals. J‐SSCG 2016 took up new subjects that were not present in SSCG 2016 (e.g., ICU‐acquired weakness [ICU‐AW], post‐intensive care syndrome [PICS] , and body temperature management). The J‐SSCG 2020 covered a total of 22 areas with four additional new areas (patient‐ and family‐centered care, sepsis treatment system, neuro‐intensive treatment, and stress ulcers). A total of 118 important clinical issues (clinical questions, CQs) were extracted regardless of the presence or absence of evidence. These CQs also include those that have been given particular focus within Japan. This is a large‐scale guideline covering multiple fields; thus, in addition to the 25 committee members, we had the participation and support of a total of 226 members who are professionals (physicians, nurses, physiotherapists, clinical engineers, and pharmacists) and medical workers with a history of sepsis or critical illness. The GRADE method was adopted for making recommendations, and the modified Delphi method was used to determine recommendations by voting from all committee members. As a result, 79 GRADE‐based recommendations, 5 Good Practice Statements (GPS), 18 expert consensuses, 27 answers to background questions (BQs), and summaries of definitions and diagnosis of sepsis were created as responses to 118 CQs. We also incorporated visual information for each CQ according to the time course of treatment, and we will also distribute this as an app. The J‐SSCG 2020 is expected to be widely used as a useful bedside guideline in the field of sepsis treatment both in Japan and overseas involving multiple disciplines.

    Abstract: Carbapenem Resistant Enterobacterales (CRE) are an urgent public health threat. We describe the clinical and molecular epidemiology of CRE infection in a multicenter pediatric cohort. Methods Patients under 18 years of age with CRE positive cultures between April 30 2016 and August 31 2017 were identified from among 49 hospitals participating in the Consortium on Resistance Against Carbapenems in Klebsiella and Other Enterobacteriaceae. Isolates representing colonization or infection were included. Bacterial identification and antimicrobial susceptibility testing were performed in each contributing clinical microbiology laboratory. Carbapenem resistance was defined per CDC criteria as those isolates displaying imipenem, doripenem, or meropenem MIC ≥4 μg/mL or ertapenem MIC ≥2 μg/mL. Clinical and epidemiological data were obtained from the electronic health record. Carbapenemase genes were detected using PCR. Results 51 pediatric patients with CRE were identified at 17 hospitals. All regions of the United States were represented, with highest prevalence in the South (46%), followed by the Northeast (24%), Midwest (20%) and West (10%). The mean age at time of positive culture was 4 years. 66% of children were under age 2. 53% were male. 40% were white, 38% black, and 18% Hispanic. Mean time from admission to culture was 25 days. 72% of children were in an ICU at the time of culture, including 18% in the neonatal ICU. 42% required mechanical ventilation prior to culture. History of malignancy was present in 14% of children. The most common source was urine (31%), followed by respiratory (25%), and blood (18%). The most common species were Enterobacter cloacae (29%), Klebsiella pneumoniae (24%) and E. coli (20%). Carbapenemase genes were detected in 8 out of 35 (23%) isolates tested. 90-day mortality was 18%. Mortality was highest for K. pneumoniae (42%). The majority of subjects (88%) did not receive effective antibiotic therapy on the day of culture collection. Table 1 Table 2 Conclusion CRE infection or colonization in children in the U.S. was geographically widespread, likely hospital-acquired, and associated with high mortality. A significant portion of patients were infants. Ineffective antibiotic therapy was common at illness onset. Disclosures W.

    Abstract: Ceftazidime-avibactam (CAZ-AVI) is used to treat multidrug-resistant infections. There are limited pharmacokinetic (PK) data among critically-ill patients (pts) and no dosing recommendations for those receiving continuous renal replacement therapy (CRRT). Methods We conducted a PK study of CAZ-AVI among pts with and without CRRT. Serial blood samples were collected at 0 (pre-dose), 2, 4, 6, and 8 hours after CAZ-AVI administration. All doses were infused over 2h. Samples were centrifuged and plasma stored at -80°C until analysis by a Shimadzu Nexera XD UHPLC with a Shimadzu 8045 MS. Transitions were monitored in positive mode for CAZ (m/z 274.05 & lt; 80.05) and negative mode for AVI (264.00 & lt; 95.90). The assay was reproducible and linear over a range of 0.1 – 20 µg/mL for AVI and 1 – 200 µg/mL for CAZ. non-compartmental analyses were used. Results 96 plasma samples from 20 pts were included in the study. Median age was 56 years (range: 31 – 74), 55% were male, and 90% were in the ICU at the time of collection. CZA dosing regimens included 2.5g IV q 8h (n=15), 1.25g IV q 8h (n=2), 0.94g IV q 24h (n=1), and 0.94g IV q 48h (n=2). 7 pts received CRRT (median blood and dialysate flow rates were 250 mL/min and 2.5 L/h, respectively; 86% received 2.5g IV q 8h) and 2 pts received intermittent hemodialysis (iHD). Among remaining pts, median creatinine clearance (CrCl) by Cockcroft-Gault was 91ml/min (range: 37 – 168 ml/min). PK values for CAZ and AVI are shown in the Table. Individual concentration-time profiles for patients receiving 2.5g IV q 8h are shown in the Figure. For patients receiving 2.5g IV q8h, CAZ and AVI median (IQR) AUCs were 525.6 hr*µg/ml (403.2, 762.0) and 83.7 (57.3, 129.5), respectively. For those on CRRT receiving the same dose, CAZ and AVI median (IQR) AUCs were 450.2 (450.0, 558.4) and 102.4 (100.7, 142.3), respectively. CAZ pharmacodynamics (PD) targets of 100% fT & gt; 1x and 4x MIC were achieved in 90% and 55% of pts, respectively. AVI PD targets of 100% fT & gt; 1 and 2.5µg/mL were achieved in 100% and 80% of pts, respectively. Treatment-emergent adverse events were not reported in any case. Ceftazidime and avibactam pharmacokinetic parameters among critically-ill patients Conclusion Among this cohort of critically-ill pts, CAZ and AVI exposures varied; however, most pts achieved PD targeted exposures, including those patients receiving CRRT and a standard dosing regimen of 2.5g IV q 8h.

    Abstract: The molecular epidemiology of carbapenem-resistant Klebsiella species is not well investigated in Qatar. The objective of this work was to characterize the genetic context of carbapenemase-producing Klebsiella isolates recovered from clinical specimens. Methods Klebsiella isolates (n=100) were collected at 7 tertiary hospitals from 2015-2017. Identification and susceptibility testing were performed using MALDI-TOF MS and BD Phoenix system, respectively. Whole Genome Sequencing was performed on the Illumina NextSeq platform. Phylogenomic analysis, screening of resistance and virulence genes, and comparison of genetic environment of carbapenemase were carried out. Results Klebsiella pneumoniae was common (80), followed by K. quasipneumoniae (16), K. aerogenes (3) and K. oxytoca (1). The most prevalent were genes encoding NDM-1 (39), OXA-48 (20), OXA-232 (10) and OXA-181 (12). KPC-2 (3) and KPC-3 (2) were also identified; no carbapenemase-encoding genes could be identified in 15 isolates. Plasmid locations of 24 carbapenemase-encoding genes were determined; blaNDM-1 was localized on IncFII replicon, while blaOXA-181 and blaOXA-232 were commonly associated with ColKP3 plasmids. pOXA-48-like plasmid was detected in 17/20 isolates harboring blaOXA-48. blaKPC-3 was located on a contig with ‘traditional’ Tn4401a mobile genetic element. Sequence types (STs) were diverse and the ‘traditional’ clonal group (CG) 258 was rare. K. pneumoniae ST147 was predominant (13), followed by ST231 (7) and ST11 (5). Nine K. quasipneumoniae isolates belonged to ST196 and were highly clonal. The virulence loci such as yersiniabactin (ybt) and rmpA were not detected within the study’s K. quasipneumoniae isolates. Amongst K. pneumoniae, there were 50 ybt+ isolates; 8 isolates had rmpA, and of these, 3 belonged to ST383. K. pneumoniae serotype K2, the capsular serotype associated with invasive liver abscess syndrome, was detected in 5 isolates. Genetic relationship of carbapenem-resistant Klebsiella pneumoniae and K. quasipneumoniae isolates in Qatar inferred from core genome SNPs. The tree is overlaid with predicted antimicrobial resistance genes and virulence factors for each isolate. Conclusion The predominant carbapenemases among clinical Klebsiella species isolates in Qatar are NDM and OXA-48 like enzymes, disseminated through various plasmids. The detection of carbapenemase-producing isolate bearing rmpA and serotype K2 reflect the presence of both multidrug resistance and hypervirulence in K. pneumoniae.

    Abstract: The CREDIBLE-CR study assessed the efficacy and safety of cefiderocol (CFDC), a novel siderophore cephalosporin, in the treatment of serious infections due to carbapenem-resistant (CR) Gram-negative (GN) bacteria. Methods CREDIBLE-CR was an open-label, prospective, randomized 2:1, Phase 3 study (NCT02714595) in patients with nosocomial pneumonia (NP), bloodstream infections/sepsis (BSI/Sepsis), or complicated urinary tract infections (cUTI) with evidence of CR GN pathogens. Adults received intravenous CFDC 2 g, q8h, 3-h infusion or best available therapy (BAT; up to 3 drugs) for 7–14 days (extendable to 21 days). The primary endpoint at test of cure in the CR microbiological intent-to-treat (CR-MITT) population was clinical cure (NP, BSI/Sepsis) or microbiological eradication (cUTI). Secondary endpoints were clinical and microbiological outcomes, all-cause mortality (ACM) and safety. Only descriptive statistics were pre-specified. Results A total of 101 patients received CFDC and 49 received BAT (CR-MITT: CFDC n=80, BAT n=38): 50% had pneumonia, 31.4% BSI/Sepsis, and 18.6% cUTI (Table 1). Most frequent CR pathogens were Acinetobacter baumannii (45.8%), Klebsiella pneumoniae (37.3%), and Pseudomonas aeruginosa (23.7%). CFDC monotherapy was given to 83% of patients, while BAT monotherapy to 29% of patients. Primary outcome in the CFDC and BAT arms was achieved in 50.0% and 52.6% in NP, 43.5% and 42.9% in BSI/Sepsis, and 52.9% and 20.0% in cUTI patients (Figure). CFDC was highly efficacious vs CREs and NDM-producing pathogens. Day 28 ACM was 24.8% (25/101) with CFDC and 18.4% (9/49) with BAT. Rescue therapy was given more frequently in the BAT than CFDC arm. Mortality results by pathogen showed an imbalance in Acinetobacter spp. infections (Table 2) with a higher rate in the CFDC arm than BAT arm. ICU and shock at randomization were more frequent in the CFDC arm than in the BAT arm in Acinetobacter spp. infections (Table 2). No safety concerns related to CFDC emerged. Table 1. Baseline demographics and characteristics (CR-MITT population) Figure. CREDIBLE-CR study primary efficacy endpoints and secondary outcomes at test-of-cure visit in CR-MITT population. Table 2. All-cause mortality by baseline pathogen inpatients with or without Acinetobacter spp. infection (safety population) Conclusion Efficacy of CFDC was demonstrated in this descriptive pathogen-focused study, including CREs, metallo-NDM producers and CR non-fermenters. Baseline imbalances of ICU and shock in the subset of infections with Acinetobacter spp. may have contributed to the mortality difference between CFDC and BAT arms.

    Abstract: Carbapenem-resistant Acinetobacter baumannii (CRAb) is one of the most problematic antimicrobial-resistant bacteria. We sought to elucidate the international epidemiology and clinical impact of CRAb. Methods In a prospective observational cohort study, 842 hospitalized patients with a clinical CRAb culture were enrolled at 46 hospitals in five global regions between 2017 and 2019. The primary outcome was all-cause mortality at 30 days from the index culture. The strains underwent whole-genome analysis. Results Of 842 cases, 536 (64%) represented infection. By 30 days, 128 (24%) of the infected patients died, ranging from 1 (6%) of 18 in Australia-Singapore to 54 (25%) of 216 in the United States and 24 (49%) of 49 in South-Central America, whereas 42 (14%) of non-infected patients died. Bacteremia was associated with a higher risk of death compared with other types of infection (40 [42%] of 96 vs. 88 [20%] of 440). In a multivariable logistic regression analysis, bloodstream infection and higher age-adjusted Charlson comorbidity index were independently associated with 30-day mortality. Clonal group 2 (CG2) strains predominated except in South-Central America, ranging from 216 (59%) of 369 in the United States to 282 (97%) of 291 in China. Acquired carbapenemase genes were carried by 769 (91%) of the 842 isolates. CG2 strains were significantly associated with higher levels of meropenem resistance, yet non-CG2 cases were over-represented among the deaths compared with CG2 cases. Conclusions CRAb infection types and clinical outcomes differed significantly across regions. While CG2 strains remained predominant, non-CG2 strains were associated with higher mortality.

    Abstract: The mortality rate for Enterococcus faecalis infective endocarditis (EIE) is high. Ampicillin-ceftriaxone (AC) has emerged as an alternative antibiotic regimen with lower toxicity compared to ampicillin-gentamicin (AG), but evidence regarding its success in reducing EIE-associated mortality in the United States is limited. We retrospectively compared mortality in EIE patients treated with AG versus AC. Methods We conducted a retrospective, propensity score-matched, cohort analysis of EIE patients treated with AG or AC from 2010 to 2017 at three hospitals in Pittsburgh, Pennsylvania. Patients were included in the analysis if they were treated for EIE with either AC or AG as the pathogen-directed antibiotic regimen for at least forty-eight hours. We assessed 90-day mortality as the primary outcome, and in-hospital mortality, length of hospital stay, hospital readmissions, adverse events, and relapse of bacteremia as the secondary outcomes. Results A total of 190 patients with EIE (100 treated with AC and 90 with AG) were included. Ninety-day mortality was significantly higher in the AC group than the AG group (21% vs 8%, p = 0.02). After propensity score-matching, 56 patients in each group remained for the outcomes analysis. We observed similar rates of 90-day mortality (6% vs 4%, p = 0.55), bacteremia relapse (0 patients in both cohorts), treatment failure (0% vs 1%, p = 0.50), and 90-day hospital readmission (24% vs 23%, p = 0.85) in the AC and AG-treated patient cohorts. Adverse events were more common in patients treated with AG, and more patients in the AG cohort switched antibiotic regimens than in the AC group. Conclusion EIE patients treated with AC have similar mortality rates as those treated with AG, while AG is associated with increased toxicity and adverse events. Larger, multi-center studies are still needed to compare the two antibiotic regimens. Disclosures All Authors: No reported disclosures

    Abstract: Carbapenem-resistant gram-negative bacilli (CRGNB) are increasingly reported around the world as a cause of serious infections. However, the epidemiology and clinical course of patients with CRGNB in Japan is not well understood. Methods We prospectively collected CR cases from 4/2019 to 9/2020 in Multi-Drug Resistant organisms clinical research network (MDRnet) consisting of 5 tertiary care facilities in Japan. We looked for all CRGNB, and all unique patients with CR Enterobacterales, CR nonfermenting gram-negative bacilli (NFGNB) and CR Aeromonas sp. isolation were included. Carbapenem resistance was tested by agar dilution method and defined based on the CLSI criteria for each species. Infections were determined by NHSN protocols. Results In total, 156 patients (30 Enterobacterales, 119 NFGNB, 7 Aeromonas spp.) were included (11 Enterobacter spp., 11 Klebsiella spp., 86 Pseudomonas aeruginosa, 29 Stenotrophomonas maltophilia, 7 Aeromonas spp.). Acinetobacter sp. was not detected. Isolation sites were sputum (n = 12) and urine (n = 7) in Enterobacterales, sputum (n = 62) and blood (n = 18) in NFGNB, and blood (n = 6) in Aeromonas spp. The median age and male ratio of the patients were 68 years [IQR: 53-74] and 19 (63.3%) in Enterobacterales, 72 years [IQR: 60-79] and 70 (58.8%) in NFGNB and 78 years [IQR: 54-83] and 2 (28.6%) in Aeromonas spp. Ten (33.3%) patients with Enterobacterales, 55 (46.2%) patients with NFGNB, and 6 (85.7%) patients with Aeromonas spp. were infected cases. The others were considered as colonized. There were no patients with ICU stay or intubation in Enterobacterales, while 5 (4.2%) and 4 (3.4%) patients were in ICU and intubated in NFGNB, and 2 patients were in ICU and intubated in Aeromonas spp., respectively. All-cause 30-day mortality rates were 10% in Enterobacterales, 16.8 % in NFGNB and 28.6% in Aeromonas spp. In the infected patients, 3 patients (30%) with Enterobacterales, 12 patients (21.8%) with NFGNB and 1 patient (16.7%) with Aeromonas spp. died within 30 days after isolation. Flow diagram outlining the characteristics of the patients and species in this study. Kaplan-Meier survival curves of patients with carbapenem resistant Enterobacterales Kaplan-Meier survival curves of patients with carbapenem resistant nonfermenting gram-negative bacilli Conclusion Mortality rates were high in infected cases of CR Enterobacterales, CR NFGNB and CR Aeromonas spp. Carbapenem-resistant Acinetobacter spp. was not detected, which differed from the CR epidemiology in Europe, the United States, and other Asian countries.
