Abstract
PURPOSE The clinical efficacy and safety of ertapenem use in patients undergoing renal replacement therapies (RRT) are not well-documented. Therefore, we aimed to investigate the safety and efficacy of ertapenem in patients with sepsis secondary to Enterobacterales who are undergoing RRT. METHODS A retrospective cohort study was conducted on patients who met the inclusion criteria at our hospital between May 2015 and December 2021. The primary endpoint was 30-day mortality. Secondary endpoints included clinical cure, microbiologic cure, recurrence rate, and incidence of seizures. RESULTS During the study period, 158 patients met the inclusion criteria. Of these, 86 were male (54.4%), the mean age was 66.4 ± 13.8 years, and the mean weight was 77 ± 22.4 kg. The most common diagnosis was bacteremia in 48 (30.4%) subjects, followed by urinary tract infection in 39 (24.7%) subjects, and pneumonia in 35 (22.2%) patients. The most isolated pathogens were Escherichia coli, followed by Klebsiella species. The median ertapenem dose was 0.5 g intravenously (IV) daily in those who received intermittent hemodialysis (IHD) and 1 g IV daily for those who received continuous veno-venous hemofiltration (CVVH). The 30-day mortality rate was 24%, the clinical cure rate was 89.2%, the microbiologic cure rate was 82%, the 30-day recurrence rate was 41.1%, and the incidence of seizures was 2.5%. Multivariate logistic regression analysis indicated that age (OR 1.04 [95% CI: 1.003-1.075]), being critically ill at therapy initiation (OR 2.9 [95% CI: 1.1-7.5]), and Enterobacterales other than Klebsiella species and Escherichia coli (OR 3.8 [95% CI: 1.1-12.5]) were significant independent risk factors associated with mortality in this population. Ertapenem dose was not associated with mortality. CONCLUSION Our findings suggest that the commonly used doses of ertapenem in patients undergoing IHD and CVVH are clinically effective but may pose a higher risk of seizures. A comprehensive pharmacokinetic study is needed to determine the most effective and safe dose for this population.

Abstract
BACKGROUND Major infectious diseases societies recommend the use of antimicrobials that achieve high-urinary concentrations to treat urinary tract infection (UTI), which is a concept of little relevance to the oliguric and anuric hemodialysis (HD) dependent population. Outcome studies in this population are more relevant, but unfortunately scarce. We sought to investigate the impact of different antimicrobials on clinical and microbiologic outcomes in HD dependent population. METHODS A retrospective observational study conducted at our quaternary care hospital between May 2015 and December 2019. We included all HD dependent adults diagnosed with UTIs. Our primary end points were clinical and microbiologic cure. Our secondary end points were 90-day recurrence and mortality. RESULTS Fifty-six patients were included in the study with 33 (58.9%) females, mean age of 69.9 ± 11.6 years, and mean body mass index of 27.7 ± 7.8 kg/m2 . Thirty-six subjects of the sample (64.3%) were anuric. Ninety-one percent of the patients achieved clinical cure. Out of those who had repeat cultures, 90.7% achieved microbiologic cure. Clinical and microbiologic cure rates were not significantly different between the oliguric and anuric groups. The 90-day recurrence rate was 11.1% and mortality was 19%, none of them was related to UTI. CONCLUSION Our findings demonstrate high rate of clinical and microbiologic cure in the treatment of oliguric and anuric HD dependent patients. We suggest that drug development and treatment societies to consider clinical and microbiologic outcomes in conjunction with achievable urinary concentration when making recommendations for the treatment of UTI.

Abstract
Echinocandins are generally excluded in the treatment of Candida-related urinary tract infections due to their poor urinary concentration. In the presence of fluconazole resistant Candida species, such as C. Glabrata and C. auris, alternative therapies are needed. We herein report the use of caspofungin for the treatment of 10 patients with candiduria, including C. auris. Mycological cure was achieved in 6 of 7 patients and clinical cure was achieved in 8 of 10 patients. Larger studies are needed to confirm our findings.

Abstract
Epidemiological studies show an increasing number of patients worldwide suffering from chronic kidney diseases (CKD), which are associated with a risk for progression to end-stage kidney disease (ESKD). CKD patients stage 2-5, patients with regular chronic dialysis treatment (hemo- or peritoneal dialysis), and patients suffering from kidney allograft dysfunction are at high risk to develop infections, e.g. urinary tract infections (UTI) and/or sepsis (urosepsis). These groups show metabolic disturbance, chronic inflammation, and impaired immunocompetence. Escherichia coli is still the most common pathogen in UTI. A wide variety of other pathogens may be involved in UTI. Urological interventions, catheterization, as well as repeated courses of antibiotics contribute to an increased challenge of antimicrobial resistance. The diagnosis of UTI in CKD is based on standard clinical and laboratory criteria. Pyuria (≥10 leucocytes/µl) is more often observed in patients with oligoanuria and low bacterial colony counts. The treatment strategies for this population are based on the same principles as in patients with normal renal function. However, drugs cleared by the kidney or by dialysis membranes need dose adjustment. Antimicrobials with potential systemic toxicity and nephrotoxicity should be administered with caution.

Abstract
Background This study aimed to identify metallo-β-lactamases (MBLs) and AmpC β-lactamases-producing Escherichia coli isolates obtained from hemodialysis (HD) patients with urinary tract infections (UTI). Methods and results A total of 257 HD patients with UTI were included in this study, from which 47 E. coli isolates were collected. Antibiotic susceptibility was tested by disc diffusion method. MBLs and AmpC production were phenotypically detected by imipenem-ethylenediaminetetracetate and cefoxitin/boronic acid assays, respectively. The presence of MBLs and AmpC genes was examined by polymerase chain reaction (PCR). Fosfomycin and ampicillin were the most and the least effective antibiotics against E. coli isolates, respectively. Moreover, 61.7% (29/47) of E. coli isolates were multidrug-resistant with seven different antibiotypes. Antibiotype V (AMP–CIP–IMP–MEM–CPD–CRO–CTX–GEN–LEV–SXT–TOB) was the most prevalent profile. Besides, 24 (51.1%) isolates were simultaneously resistant to imipenem and meropenem. Phenotypic assay showed MBL production in 16 (66.7%) of the 24 carbapenem-resistant E. coli isolates. The distribution of MBL genes in carbapenem-resistant E. coli was as follows: blaIMP 18 (72%), blaVIM 7 (28%), and blaNDM 1 (4%). AmpC was detected in 61.7% (29/47) of the isolates using the phenotypic method. The presence of AmpC genes was confirmed by PCR in only 26 of 29 (86.7%) AmpC producers. The frequencies of blaDHA-1, blaACC, and blaCMY-2 were 6 (20.7%), 11 (37.9%), and 21 (72.4%), respectively. Conclusions The emergence of MBL and AmpC coproducing E. coli isolates calls for an urgent surveillance program for timely diagnosis and screening of these genes in our healthcare systems.

Abstract
Patients with end-stage renal disease (ESRD) requiring intermittent hemodialysis (IHD) are at increased risk of infection, which represents a leading cause of mortality in this population. The use of additional vascular access devices such as peripherally inserted central catheters to treat such infections should be minimized in patients with ESRD requiring IHD in order to mitigate complications such as infection and thrombosis and to maintain venous patency for hemodialysis access. Intravenous antimicrobial dosing following IHD has the advantages of avoiding additional access devices and providing convenience for patients and providers. Vancomycin, cefazolin, and aminoglycosides have historically been regarded as the primary intravenous antimicrobials administered with IHD given their relatively low cost, convenient dosing, and longevity of clinical use. Despite this, a growing body of literature is evaluating the use of an expanded list of antimicrobials that may be employed using post-dialysis dosing for patients requiring IHD; however, the available data are largely limited to pharmacokinetic studies and small cohorts of infected patients or uninfected subjects. Post-dialytic dosing of intravenous antimicrobials may be considered on a patient-by-patient basis after careful consideration of clinical, microbiological, and logistical factors that may influence the probability of treatment success. This document reviews and evaluates currently available information on the post-dialytic administration of an expanded list of intravenous antimicrobials in the setting of thrice-weekly, high-flux IHD.

Abstract
BACKGROUND The approved dosing of ertapenem in patients with chronic kidney disease stage 5 utilizing dialysis (CKD-5D) is 0.5 g intravenous daily. Several reports associated this dosing strategy with neurotoxicity. OBJECTIVE The purpose of this study is to identify the incidence of neurotoxicity in this population and the risk factors associated with this toxicity. The secondary objective was to review the literature and discuss a safer/cost-effective dosing strategy based on available data. METHODS A retrospective study was conducted screening all patients who received ertapenem and hemodialysis at our quaternary hospital between May 2015 and March 2019. Patients' demographics, comorbidities, concomitant drugs (known to induce neurotoxicity), and seizure history were collected. RESULTS A total of 99 eligible patients were identified; 10 of them (10%) developed neurotoxicity. The patients who developed neurotoxicity were all male; mean age was 74 ± 9 years as compared with 68.9 ± 13 years in the sample. Bivariate relationships between all predictors and the seizures (dichotomously coded) were estimated to investigate the risk factors. The following were the significant predictors of seizures: male sex (17%; P = 0.014), dementia (27%; P = 0.012), and concomitant use of β-lactams, aminoglycosides, or fluoroquinolones (19.6%; P = 0.042). CONCLUSION AND RELEVANCE The currently approved ertapenem dose imposes a risk of developing neurotoxicity in patients with CKD-5D. Utilizing the published data in this population, alternative post-dialysis dosing strategies administered through dialysis access such as 1 g loading dose, followed by either 0.5 g (for the 48 hours interdialytic time) or 1 g (for the 72 hours interdialytic time) might warrant further investigation for efficacy and safety.
