General Items
Essential Medicines List (EML) 2019 Application for the inclusion of imipenem/cilastatin, meropenem and amoxicillin/clavulanic acid in the WHO Model List of Essential Medicines, as reserve second-line drugs for the treatment of multidrug-resistant tuberculosis (complementary lists of anti-tuberculosis drugs for use in adults and children) General items 1. Summary statement of the proposal for inclusion, change or deletion This application concerns the updating of the forthcoming WHO Model List of Essential Medicines (EML) and WHO Model List of Essential Medicines for Children (EMLc) to include the following medicines: 1) Imipenem/cilastatin (Imp-Cln) to the main list but NOT the children’s list (it is already mentioned on both lists as an option in section 6.2.1 Beta Lactam medicines) 2) Meropenem (Mpm) to both the main and the children’s lists (it is already on the list as treatment for meningitis in section 6.2.1 Beta Lactam medicines) 3) Clavulanic acid to both the main and the children’s lists (it is already listed as amoxicillin/clavulanic acid (Amx-Clv), the only commercially available preparation of clavulanic acid, in section 6.2.1 Beta Lactam medicines) This application makes reference to amendments recommended in particular to section 6.2.4 Antituberculosis medicines in the latest editions of both the main EML (20th list) and the EMLc (6th list) released in 2017 (1),(2). On the basis of the most recent Guideline Development Group advising WHO on the revision of its guidelines for the treatment of multidrug- or rifampicin-resistant (MDR/RR-TB)(3), the applicant considers that the three agents concerned be viewed as essential medicines for these forms of TB in countries. -

New Β-Lactamase Inhibitor Combinations: Options for Treatment; Challenges for Testing
MEDICAL/SCIENTIFIC AffAIRS BULLETIN New β-lactamase Inhibitor Combinations: Options for Treatment; Challenges for Testing Background The β-lactam class of antimicrobial agents has played a crucial role in the treatment of infectious diseases since the discovery of penicillin, but β–lactamases (enzymes produced by the bacteria that can hydrolyze the β-lactam core of the antibiotic) have provided an ever expanding threat to their successful use. Over a thousand β-lactamases have been described. They can be divided into classes based on their molecular structure (Classes A, B, C and D) or their function (e.g., penicillinase, oxacillinase, extended-spectrum activity, or carbapenemase activity).1 While the first approach to addressing the problem ofβ -lactamases was to develop β-lactamase stable β-lactam antibiotics, such as extended-spectrum cephalosporins, another strategy that has emerged is to combine existing β-lactam antibiotics with β-lactamase inhibitors. Key β-lactam/β-lactamase inhibitor combinations that have been used widely for over a decade include amoxicillin/clavulanic acid, ampicillin/sulbactam, and pipercillin/tazobactam. The continued use of β-lactams has been threatened by the emergence and spread of extended-spectrum β-lactamases (ESBLs) and more recently by carbapenemases. The global spread of carbapenemase-producing organisms (CPOs) including Enterobacteriaceae, Pseudomonas aeruginosa, and Acinetobacter baumannii, limits the use of all β-lactam agents, including extended-spectrum cephalosporins (e.g., cefotaxime, ceftriaxone, and ceftazidime) and the carbapenems (doripenem, ertapenem, imipenem, and meropenem). This has led to international concern and calls to action, including encouraging the development of new antimicrobial agents, enhancing infection prevention, and strengthening surveillance systems. -

Management of Penicillin and Beta-Lactam Allergy
Management of Penicillin and Beta-Lactam Allergy (NB Provincial Health Authorities Anti-Infective Stewardship Committee, September 2017) Key Points • Beta-lactams are generally safe; allergic and adverse drug reactions are over diagnosed and over reported • Nonpruritic, nonurticarial rashes occur in up to 10% of patients receiving penicillins. These rashes are usually not allergic and are not a contraindication to the use of a different beta-lactam • The frequently cited risk of 8 to 10% cross-reactivity between penicillins and cephalosporins is an overestimate based on studies from the 1970’s that are now considered flawed • Expect new intolerances (i.e. any allergy or adverse reaction reported in a drug allergy field) to be reported after 0.5 to 4% of all antimicrobial courses depending on the gender and specific antimicrobial. Expect a higher incidence of new intolerances in patients with three or more prior medication intolerances1 • For type-1 immediate hypersensitivity reactions (IgE-mediated), cross-reactivity among penicillins (table 1) is expected due to similar core structure and/or major/minor antigenic determinants, use not recommended without desensitization • For type-1 immediate hypersensitivity reactions, cross-reactivity between penicillins (table 1) and cephalosporins is due to similarities in the side chains; risk of cross-reactivity will only be significant between penicillins and cephalosporins with similar side chains • Only type-1 immediate hypersensitivity to a penicillin manifesting as anaphylaxis, bronchospasm, -

A Brief History of the Universe A. Timeline: 1940s a. β-lactams and β-lactamases i. Sir Alexander Fleming discovered penicillin from Penicillium notatum (now Penicillium chrysogenum) in 1928.1,2 ii. Chain, Florey, et al isolated penicillin in 1940, leading to its commercial production.3 iii. First β-lactamase was described as a penicillinase in Escherichia coli in 1940.4 iv. Giuseppe Brotzu discovered cephalosporin C from the mold Cephalosporin acremonium (now Acremonium chrysogenum) in 1945, but cephalosporins were not clinically used for another 2 decades.2,5 b. What are β-lactamases? i. β-lactamases are enzymes that hydrolyze the amide bond of the β-lactam ring, thereby inactivating them.6 Figure 1: Mechanism of action of β-lactamases ii. β-lactamase production is the principal mechanism by which gram-negative bacteria resist β-lactam antibiotics.6 iii. -

Here, we investigated the impact of various antimicrobials, alone and in combination, via the in vitro testing of CoR-PA clinical isolates. Eighteen CoR-PA isolates were obtained from patients treated at Phramongkutklao Hospital from January 2010 through June 2019; these were classified into six different clonal types by using the enterobacterial repetitive intergenic consensus (ERIC)-PCR method, with a high prevalence of Group A (27.8%). The antimicrobial susceptibility was determined as the minimal inhibitory concentrations (MICs) using the epsilometer-test (E-test) method. The synergistic activities of six antimicrobial combinations were reported via the fractional-inhibitory-concentration index.
