To determine current opinions among experts in pediatric infectious diseases for treatment of bacterial sepsis, meningitis and acute otitis media, we polled directors of training programs in January, 1992. Responses were received from 69 centers in the United States and Canada. For initial treatment of presumed bacterial meningitis, the third generation cephalosporins alone or combined with ampicillin have become drugs of choice in all age groups. Most infectious disease programs include dexamethasone in the management of presumed bacterial meningitis for children 2 months of age and older. Third generation cephalosporins are also drugs of choice for presumed sepsis: combined with ampicillin for infants 5 weeks of age; used alone for children 5 months and 12 years of age. Amoxicillin remains the preferred drug for initial treatment of acute otitis media. The combination of amoxicillin and clavulanic acid is favored in the setting of an increased proportion of beta-lactamase-producing bacterial pathogens. Comparison of these results with polls in 1987 and 1989 indicates a shift in recommendations of therapy of presumed bacterial sepsis and meningitis from ampicillin alone or combined with an aminoglycoside or chloramphenicol to use of a third generation cephalosporin alone or combined with ampicillin.

A 3 year old girl was admitted with suspected bacterial meningitis. The patient's history concerning renal and cerebral function and known allergies had been uneventful until that time. 36 h after initiation of a high dose antibiotic therapy with Penicillin G (0.5 Mega IE/kg/day) and Amoxicillin (400 mg/kg/day) macrohematuria and consecutive anuria was observed. Prerenal cardiocirculatory failure, a Schwartz-Bartter-reaction as well as coagulatory failure could be ruled out. There were no symptoms of hypersensitivity. Sonographic examinations of the kidneys and the urinary tract as well as urinanalysis suggested an acute tubular obstruction and papillary necrosis caused by amoxicillin. After changing the antibiotic regimen to chloramphenicol and induction of diuresis by furosemide and dopamine renal failure could be resolved within 39 h. The patient recovered completely. High dose therapy with amoxicillin (greater than 300 mg/kg/day) includes the risk of tubular obstruction due to cristalluria. Solubility of ampicillin in aqueous fluids (6.5 mg/ml at pH 7) should be supported by sufficient diuresis and urine alkalization.

The emergence of resistance has imposed a modification of the protocols for the treatment of Streptococcus pneumoniae (S pneumoniae) bacterial meningitis. Amoxicillin is no longer adapted. As resistance to C3G appeared, a synergistic effect of an association C3G + vancomycine was demonstrated. Thus currently this association should be recommended in any case of meningitis supposedly due to S pneumoniae. The treatment is then modified according to the evolution and the minimal inhibition concentration (MIC) of the bacteria. The strains carrying a high level of resistance to cephalosporin (MIC > or = 4 micrograms ml-1) or tolerant to vancomycine may cause a therapeutic failure despite an increase of the dosage of cephalosporin. Rifampicin, fosfomycine, or imipenem (despite its risk of convulsions), may represent alternative options, as long as we do not have safe quinolones active on resistant strains of S. pneumoniae. Dexamethasone has been formerly implicated in the relapse of pneumococcal meningitis. Furthermore, its use is questionable since no evidence of a therapeutic benefit has been clearly demonstrated. As a consequence of the resistance phenomenon the management of S. pneumoniae meningitis must include particular measures: at least resistance to penicillin must be checked by the oxacilline disk and the MIC to C3G must be measured by E test; aCSF sample should be obtained between 36 and 48 hours following the beginning of the treatment to check its sterilization. All recent studies have shown a similar prognosis of meningitis due to resistant S. pneumoniae as compared to those due to sensitive strains. However, these data should be interpreted with caution since in these studies, pneumococcus resistant to cephalosporin (the real problem) are not separated from those only resistant to penicillin. Furthermore, presently, the incidence of strains highly resistant to cephalosporin is still low. The new conjugated vaccine against pneumococcus should change the situation if its ability to prevent the circulation of resistant strains is confirmed.
