Seventy infants and children with bacterial meningitis were studied. All children were treated with ampicillin and chloramphenicol. A significant increase in the cerebrospinal fluid protein concentration determined on admission was found in patients who died as compared to those who survived (P less than 0.05). However, no difference was observed between the admission CSF leukocyte count in those patients who died versus those who survived. From this study, it can be concluded that the determination of CSF protein level on admission is an easy, fast and reliable method that can be used to predict clinical outcomes in acute bacterial meningitis.

This is review of our experience in the treatment of meningitis carried out at the Naval Medical Research Unit No. 3 (NAMRU-3), Cairo, Egypt since 1967. We have demonstrated that the serum and cerebrospinal fluid concentrations of ampicillin and its efficacy when used in the treatment of meningitis are comparable whether they are administered intravenously or intramuscularly. The third generation cephalosporin ceftriaxone was found to be very safe and effective when administered intramuscularly once a day in the treatment of the different types of acute bacterial meningitis. Aztreonam given intramuscularly was successful in the treatment of Gram-negative meningitis caused by multi-resistant organisms. The fatality rates and morbidity were significantly reduced in patients with meningitis when dexamethasone was given in conjunction with antibacterial chemotherapy.

We review the 257 patients hospitalized for meningitis in the Cantonal University Hospital, Geneva between 1st January 1980 and 31st December 1986. 104 patients had acute bacterial meningitis (32 Str. pneumoniae, 21 N. meningitidis, 10 Listeria monocytogenes, 8 streptococci, 5 H. influenzae, 5 staphylococci, 4 gram negative bacilli and 19 without identified bacteria), 124 patients had viral meningitis and 29 meningitis of other etiologies (6 tuberculous meningitis, 2 fungal meningitis, 1 leptospiral meningitis, 5 neoplastic meningitis--one already counted because of a meningitis due to Staph. epidermidis--2 meningitis consecutive to a meningeal irritation, 4 already treated meningitis of undetermined etiology, 2 chronic meningitis and 8 meningoencephalitis). The total mortality was 14.4%. It was zero in viral meningitis and 28% in bacterial meningitis (47% in cases of Str. pneumoniae, 5% in cases of N. meningitidis, 20% in cases of Listeria monocytogenes, 38% in cases of streptococci, 0% in cases of H. influenzae, 60% in cases of staphylococci, 50% in cases of gram negative bacilli, 16% in cases of unidentified bacteria). The striking difference in mortality emphasizes the importance of recognizing a bacterial etiology in order to institute antibiotic therapy as soon as possible. The delay between admission and lumbar puncture averaged 15 hours (range 0.25-96 h) in patients with acute bacterial meningitis and 6.3 hours (0.5-80 h) in patients with viral meningitis. The delay between admission and institution of the antibiotics averaged 5.3 hours (1-48 h) in cases of acute bacterial meningitis and 4.8 hours (0.5-48 h) in cases of viral meningitis. A better clinical workup may provide a reliable diagnosis sooner. In the collective with bacterial and viral meningitis headaches, fever or nuchal rigidity were present in over 80% of the cases. The following features were significantly associated with a bacterial etiology: age over 30 years, alcoholism, concomitant neoplasm, cough, coma, pulmonary rales, new neurological signs or petechia. At least one of these 4 latter signs was present in more than 70% of the cases with acute bacterial meningitis compared to 6% in cases of viral meningitis. Thus the clinical presentation alone serves to recognize the meningitis and to differentiate between a bacterial or viral etiology, thus permitting an immediate therapeutic decision without waiting for complementary investigations. The 104 patients with acute bacterial meningitis were treated with antibiotics: 60 with penicillin, 17 with ampicillin and 26 with other antibiotics; one case did not receive antibiotics. More than the half of the cases with viral meningitis have got antibiotics (52%).

The search for new antimicrobial agents in the treatment of bacterial meningitis is justified by a rate of mortality that currently remains unacceptably high and by the emergence of bacterial resistance. Because of their excellent in vitro activity against gram-negative organisms and good penetration into the cerebrospinal fluid, the new fluoroquinolones may have a potential role in the treatment of central nervous system (CNS) infections. Although there are few reports on the use of fluoroquinolones in treatment of patients with CNS infections, experience to date indicates that pefloxacin, the most intensively studied agent, and ciprofloxacin provide effective treatment for patients with meningitis caused by susceptible pathogens. Since they cannot be used in patients whose skeletal growth is incomplete, the place of the fluoroquinolones in the treatment of Haemophilus influenzae meningitis is obviously very limited. Neisseria meningitidis is still exquisitely sensitive to penicillin G and ampicillin, and there is thus no reason to replace these agents by fluoroquinolones, except when patients are allergic to beta-lactam agents, or when parental administration is impossible. A potential use of the new fluoroquinolones would be in the treatment of meningitis due to gram-negative bacilli, including Pseudomonas aeruginosa, and Acinetobacter.

In many pediatric infectious disease programs, ceftriaxone or cefotaxime is now the preferred drug for bacterial meningitis caused by H. influenzae, meningococci, and pneumococci. Ceftriaxone reaches a high bactericidal titer in the cerebrospinal fluid and persists at the site of infection longer than any other beta-lactam antibiotic. Short-course, once-daily therapy with ceftriaxone requires more study; currently, many pediatricians administer the agent twice daily for suspected or proven meningitis. Given the association of sequelae with prolongation of positive CSF cultures, ceftriaxone's rapid bactericidal activity is an advantage, which may require an adjunctive agent to block the inflammatory response due to antibiotic-induced release of endotoxin and other cell wall components. As empiric therapy, ceftriaxone is effective in infants and children three months to 18 years old. It is not yet recommended in neonates, because of concerns about bilirubin displacement. Thus, infants up to three months of age should receive ampicillin plus cefotaxime. In adults, ceftriaxone is effective therapy for presumed bacterial meningitis but must be combined with ampicillin initially, since L. monocytogenes meningitis cannot be excluded in most cases until CSF culture results are available.

Eighty-seven infants and children aged 1 month to 15 years admitted to the Pediatric Department, Randers Central Hospital 1975-1988 with bacterial meningitis were evaluated with special interest in the course of fever and its relation to sequelae. The children were treated with ampicillin (400 mg/kg/day). We found that 94% were afebrile after six days. 10% had persisting fever, 1% prolonged fever and 38% were found to develop secondary fever. Significantly more children infected with H. Influenzae had secondary fever. In most cases, no reason for secondary fever was found (46%). 18% had drug fever and only one case of relapse was found. 23% had severe sequelae. No significant relationships between persistent, prolonged or secondary fever and sequelae were found.

Ampicillin (or penicillin G) plus chloramphenicol, cefuroxime, ceftriaxone, and cefotaxime have been used in the treatment of bacterial meningitis beyond the neonatal period. Review of recent data from the USA and Europe indicates that delayed CSF sterilization occurs significantly more often with ampicillin/chloramphenicol and cefuroxime than with ceftriaxone and cefotaxime. Delayed CSF sterilization is associated with an increased morbidity and neurological complications. Previously reported in vitro interactions between chloramphenicol and various beta-lactam antibiotics indicate that for bacteria where chloramphenicol is only bacteriostatic, the combination of chloramphenicol with beta-lactams is antagonistic. Killing rates of various beta-lactams were compared against a number of gram-positive and gram-negative bacteria. Cidal activity of some beta-lactams was inoculum dependent. There was a good correlation between in vitro activity and ability to sterilize CSF. Ceftriaxone is highly protein bound and its use in newborns is discouraged. Diarrhea occurs significantly more often after cefriaxone use than after the use of other agents. Ceftriaxone is uniquely associated with a high frequency of biliary pseudolithiasis which may be symptomatic and can cause measureable morbidity. In selecting the "proper" antimicrobial agent for the treatment of bacterial meningitis considerations should be given to proven clinical efficacy, prompt CSF sterilization, rapid in vitro cidal activity, safety and cost. We recommend cefotaxime as the agent of choice in the treatment of bacterial meningitis.

We report the unusual case of a two year old boy with encephalomeningitis caused by Listeria monocytogenes. The patient was hospitalized with the classical signs of severe bacterial meningitis. The microbiological investigations gave proof of Listeria monocytogenes as causative agent 36 hours later. Antibiotic treatment with ampicillin and gentamicin resulted in a prompt improvement of the boy's condition. The boy was discharged four weeks later.

Antibiotic susceptibilities of 38 type b Haemophilus influenzae and 28 Streptococcus pneumoniae strains isolated from cerebrospinal fluid, blood and other specimens between 1973 and 1988 were studied. Minimal inhibitory concentrations (MICs) of ampicillin against 10 beta-lactamase positive and 28 negative H. influenzae isolates were 32-64 and 0.25 micrograms/ml, respectively. The MIC of chloramphenicol against one of the beta-lactamase positive H. influenzae strains was 8 but MICs against the rest of the organisms were 0.5-1 micrograms/ml. MICs of cefotaxime, ceftriaxone and cefuroxime against all H. influenzae strains were 0.016, 0.008 and 0.5 micrograms/ml, respectively. No S. pneumoniae isolates were resistant to penicillin G and MICs of this drug were 0.016-0.032 micrograms/ml. MICs of cefotaxime, cefriaxone and cefuroxime against all S. pneumoniae strains were 0.016-0.032, 0.016-0.032 and 0.032-0.063 micrograms/ml, respectively. MICs of chloramphenicol against 15, 4 and 9 of S. pneumoniae isolates were 2, 8 and 16 micrograms/ml, respectively. Antibiotic concentrations in the cerebrospinal fluid of patients with bacterial meningitis after intravenous administration of ampicillin (50-70 mg/kg x 4/day), penicillin G (31-63 mg/kg x 4/day), cefotaxime (50 mg/kg x 4/day) and chloramphenicol (25 mg/kg x 4/day) were 4.70 +/- 1.83 (n = 11), 0.57 +/- 0.32 (n = 7), 4.97 +/- 2.60 (n = 9) and 8.52 +/- 3.54 micrograms/ml (n = 3), respectively. The initial choice of antibiotics in older children with bacterial meningitis is a combination of ampicillin (75 mg/kg x 4/day) and cefotaxime (50 mg/kg x 4/day) to cover ampicillin-resistant H. influenzae, S. pneumoniae, and Listeria monocytogenes in Japan. These antibiotics should be changed according to the causative organisms and their antibiotic susceptibilities.
