Expert Committee recommendation
The Expert Committee endorsed the inclusion on the EML and EMLc of ceftriaxone or cefotaxime as first-choice option for use in suspected acute bacterial meningitis and of chloramphenicol, benzylpenicillin, ampicillin or amoxicillin as second-choice therapy, recognizing that the last three beta-lactams may be added as first-choice options in some countries for suspected acute bacterial meningitis in particular when Listeria is suspected. The Committee recommended the addition of meropenem to the EMLc for use in neonates as a second-choice option to treat suspected acute bacterial meningitis where resistant Gram-negative organisms are the common causative agents.
Acute bacterial meningitis is a medical emergency requiring prompt administration of antibiotics that penetrate well into inflamed meninges. Because of the severity of this infection, evidence from randomized controlled trials (RCTs) is limited; recommendations for antimicrobials are driven largely by susceptibility patterns of the most common pathogens together with experimental work in animal models.
Summary of evidence
In a 2015 systematic review, chloramphenicol was compared with two penicillins, two cephalosporins and one tetracycline (5 RCTs; 1753 patients) (1). Chloramphenicol was associated with higher mortality than the other antibiotics (risk ratio (RR) 1.27; 95% confidence interval (CI) 1.00–1.60). In contrast, a 2007 Cochrane review (19 RCTs; 1496 patients) that compared third-generation cephalosporins with treatment with penicillin or ampicillin-chloramphenicol found no differences in mortality (risk difference (RD) 0%; 95% CI 3% to 2%), risk of deafness (RD –4%; 95% CI –9% to 1%), or risk of treatment failure (RD –1%; 95% CI –4% to 2%) (2) . There was a reduced risk of CSF culture positivity after 10–48 hours (RD –6%; 95% CI –11% to 0%) and an increased risk of diarrhoea (RD 8%; 95% CI 3% to 13%) for third-generation cephalosporins compared with penicillin/ampicillin-chloramphenicol (2). A 2009 systematic review compared short-course (4–7 days) and long-course (7–14 days) antibiotics in children (5 RCTs; 426 patients) and found no difference in clinical success (odds ratio (OR) 1.24; 95% CI 0.73–2.11), long-term neurological complications (OR 0.60: 95% CI 0.29–1.27) or long-term hearing impairment (OR 0.59; 95% CI 0.28–1.23) (3).
The National Institute for Health and Care Excellence (NICE) guidelines recommend ceftriaxone for patients aged 3 months and older, while younger infants should be treated with IV cefotaxime plus amoxicillin or ampicillin (4). It is also recommended that vancomycin be added for patients who have received prolonged or multiple exposures to antibiotics within the previous 3 months and for those who have recently travelled outside the United Kingdom. IDSA (Infectious Diseases Society of America) guidelines recommend ampicillin and cefotaxime or an aminoglycoside for children less than 1 month of age, vancomycin and ceftriaxone or cefotaxime for children older than 23 months and adults up to 50 years of age, and addition of ampicillin for patients over 50 years for coverage of Listeria monocytogenes (5). Vancomycin plus cefepime, ceftazidime or meropenem is recommended for patients with penetrating trauma, who are post-neurosurgery or have a cerebrospinal shunt in place.
Rationale for antibiotic selection
Systematic review evidence suggests that chloramphenicol is associated with higher mortality than other antibiotics; it was therefore not proposed as a core antibiotic. Ampicillin, ceftriaxone and cefotaxime are proposed for multiple indications and are categorized as core, while aminoglycosides and vancomycin have more specific indications (e.g. by age or indication) and are therefore categorized as targeted, as are ceftazidime and meropenem.
For common community-acquired infections, the main focus has been on empirical treatment choices that are broadly applicable in most countries. Generally, alternatives for use in case of allergy were not considered. The Committee considered the various antibiotics proposed in the application under the guiding principle of parsimony and selected first- and second-choice antibiotics for this indication for inclusion on the EML and/or EMLc. Ceftazidime, amikacin, gentamicin and vancomycin were excluded, because the Committee considered that these antibiotics have limited or no indications in community-acquired acute bacterial meningitis. The Committee recommended the inclusion of chloramphenicol as a second-choice option, particularly for epidemic bacterial meningitis. Recommended first- and second-choice antibiotics are reported above. The first-choice antibiotics are those generally recommended on the basis of available evidence and are usually narrow-spectrum agents.
