Background: In recent years, Extended-spectrum beta-lactamase (ESBL) producing microorganisms have complicated treatment of infections due to resistance of ESBL producing strains to a wide range of antimicrobials. Objective: Target of this study was to determine the prevalence of ESBL producing gramnegative bacteria in neonatal sepsis cases and to reveal the antimicrobial susceptibility pattern of those isolated ESBL producers. Materials and Methods: This cross sectional study was carried out in Dhaka Medical College Hospital (DMCH) over a period of 12 months from January to December in 2016. Following isolation and identification of gram-negative bacteria from blood samples of suspected septicemic neonates, antimicrobial susceptibility test was performed by Kirby Bauer disk-diffusion method and ESBL producers were detected by Double Disk Synergy (DDS) test. Results: Among 52 Gram-negative bacteria isolated from 106 blood samples, 34.61% ESBL producers were detected and Enterobacter spp. (45%) was predominant followed by Klebsiella pneumoniae (33.33%). None of the ESBL producers was resistant to colistin and tigecycline. All ESBL producing Acinetobacter baumannii, 77.78% and 66.67% of ESBL producing Enterobacter spp and Klebsiella spp. respectively showed resistance to meropenem. All ESBL producers were resistant to piperacillintazobactam. Conclusion: Appropriate measures should be taken to prevent the spread of ESBL producing strains by combining strategies for infection prevention, control and rational use of antibiotics.

ABSTRACT Cefiderocol is a newly approved siderophore cephalosporin that demonstrates expanded in vitro activity against multidrug-resistant Gram-negative bacteria. In two challenging cases reported here, cefiderocol shows potential utility as salvage therapy against difficult-to-treat pathogens with limited or no treatment options; however, two multicenter, randomized clinical trials have yielded mixed results among cefiderocol-treated patients. Taken together, clinicians must balance a clear need for cefiderocol in clinical practice with the uncertainties that have stemmed from the available data.

AbstractAntimicrobial resistance has become one of the greatest threats to public health, with rising resistance to carbapenems being a particular concern due to the lack of effective and safe alternative treatment options. Carbapenem-resistant gram-negative bacteria of clinical relevance include the Enterobacteriaceae, Pseudomonas aeruginosa, Acinetobacter baumannii, and more recently, Stenotrophomonas maltophilia. Colistin and tigecycline have been used as first-line agents for the treatment of infections caused by these pathogens; however, there are uncertainties regarding their efficacy even when used in combination with other agents. More recently, several new agents with activity against certain carbapenem-resistant pathogens have been approved for clinical use or are reaching late-stage clinical development. They include ceftazidime-avibactam, ceftolozane-tazobactam, meropenem-vaborbactam, imipenem-cilastatin-relebactam, plazomicin, eravacycline, and cefiderocol. In addition, fosfomycin has been redeveloped in a new intravenous formulation. Data regarding the clinical efficacy of these new agents specific to infections caused by carbapenem-resistant pathogens are slowly emerging and appear to generally favor newer agents over previous best available therapy. As more treatment options become widely available for carbapenem-resistant gram-negative infections, the role of antimicrobial stewardship will become crucial in ensuring appropriate and rationale use of these new agents.
