A retrospective study was carried out at Dayanand Medical College & Hospital, Ludhiana (Punjab) during the period from January 1985 to June 1990 to know the incidence of meningococcal meningitis. Meningococcal etiology was established in 170 (49.41%) cases out of 344 cases of bacterial meningitis. Out of 170 cases of meningococcal meningitis, 74 (43.52%) were positive only by smear examination, 90 (52.94%) were positive both by smear as well as culture and there were six (3.52%) cases which were positive only by culture. The organisms were sensitive to most of the common antibiotics including penicillin, chloramphenicol, ampicillin and sulphadiazine.

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 retrospective review of 71 paediatric patients admitted with bacterial meningitis to the King Fahad Hospital at Al-Baha, Saudi Arabia, during an 8-year period revealed a preponderance of males (67.6%) and young subjects with 88.7% being below 24 months of age. The commonest cerebrospinal fluid pathogens in the series were Haemophilus influenzae type B (HIB), Streptococcus pneumoniae and Group B-beta haemolytic streptococcus, which were responsible for 47.3, 34.5 and 9.1% of cases respectively. Neisseria meningitidis which is a major cause of meningitis in most other reports was uncommon in the present series, and was isolated from only two patients. All the children with Group B-beta haemolytic streptococcal meningitis were below 3 months of age while 96.2% of the children with HIB meningitis were younger than 2 years. Mortality was highest (40%) among the infants with Group B-beta haemolytic streptococcal meningitis. Six (23.1%) of the HIB isolated were resistant to ampicillin and two (7.7%) were resistant to both ampicillin and chloramphenicol. There is a need for greater emphasis on prevention through the use of available vaccines including the newly introduced conjugate vaccines against HIB which are capable of eliciting immune responses in infants as young as 2 months.

In most developing countries, bacterial meningitis (BM) is associated with a high case-fatality rate. The search for a simple, convenient, and inexpensive antibiotic treatment remains a priority. In this study, a non-blinded, multicentre, randomised clinical trial of 528 cases of BM was done in two hospitals in Mali and Niger, between March, 1989, and May, 1990, to see whether a double injection of long-acting chloramphenicol (on admission to hospital and 48 h later) is as effective as a course of intravenous ampicillin (8 days, 4 times a day). The cumulative case-fatality rate on day 4 (principal end-point) among the chloramphenicol (254 patients) and ampicillin (274) groups were, respectively, 28% and 24.5% (relative risk 1.14, 95% confidence interval 0.86-1.52). No outbreak occurred during the study period. The hospital case-fatality rate was 33.1%. Main risk factors for death were associated with clinical condition on admission--ie, altered consciousness, convulsions, or dehydration. The case-fatality rates were 13% (21/161) for Neisseria meningitidis, 36.1% (48/133) for Haemophilus influenzae, and 67% (77/115) for Streptococcus pneumoniae. In a multiple logistic regression model, controlling for the differential distribution of potential risk factors (including bacterial species), there was no difference between treatment groups. Our findings suggest that long-acting chloramphenicol is a useful first-line presumptive treatment for BM in high-incidence countries.

A prospective 6-month study in Yaounde evaluated 49 children aged from 2 months to 8 years, hospitalized with bacterial meningitis. They were randomly assigned to one of two initial treatment groups, either an ampicillin-chloramphenicol combination (group A) or chloramphenicol alone (group B). The majority of patients were infected with Haemophilus influenzae, and the majority of deaths were caused by Streptococcus pneumoniae. Altogether, 17.9% of Haemophilus influenzae isolates were ampicillin-resistant and 3.6% chloramphenicol-resistant. We found no isolate resistant to both antibiotics. Response to both treatments was similar in both groups. The theoretical risk of treatment failure with ampicillin was higher than with the ampicillin-chloramphenicol combination (p less than 0.05). There was no statistically significant difference between the risk of treatment failure with the ampicillin-chloramphenicol combination and the risk with chloramphenicol alone (p less than 0.05), but the latter was increased by the occurrence of chloramphenicol-resistant isolates of Streptococcus pneumoniae (11.1%). Although treatment with an ampicillin-chloramphenicol combination is four times more expensive than treatment with chloramphenicol alone, costwise it is also one-quarter the price of a third-generation cephalosporin (moxalactam). At present, the ampicillin-chloramphenicol combination can be suggested as the first choice for initial treatment considering both the epidemiological data and the cost/efficiency ratio in the area of Yaounde.

Nine cases, 3 adults and 6 children, with Listeria monocytogenes meningitis were seen over a 10-year period at King Edward VIII Hospital, Durban. These cases accounted for 0.8% (3/374) and 0.6% (6/1,210) of all culture-positive cases of acute bacterial meningitis in adults and children, respectively, and represented 2.9% (4/136) of all culture-positive cases in the neonatal age group and 5.7% (3/53) of culture-positive cases in adults 50 years and older. The patients had positive blood and cerebrospinal fluid (CSF) cultures. All isolates were sensitive to ampicillin, chloramphenicol, sulphamethoxazole-trimethoprim combination and gentamicin. One isolate in an 11-month-old child was resistant to penicillin and 2 isolates in the adult patients displayed intermediate sensitivity to this antibiotic. The adults were over 50 years of age and presented with an abrupt onset of a pyrexial illness, meningitis and focal neurological signs; only 1 survived. Only 1 8-week-old infant of the paediatric cases survived. A polymorphonuclear leucocytosis, low serum glucose and elevated protein values were common findings in the CSF and the features in some patients mimicked tuberculous or viral meningitis. The fulminant course of the disease and the fact that penicillin and not ampicillin is the first-line antibiotic makes it essential to consider listeriosis as a possible diagnosis, particularly in the very ill patient.

The initial treatment of infantile and childhood bacterial meningitis is now well standardized, but three current aspects are discussed in this paper. Although classically, ampicillin can still be given as the initial treatment of bacterial meningitis in children, current epidemiologic data demonstrate the emergence of resistant strains of Haemophilus and Pneumococcus, and consequently use of a third-generation cephalosporin should be preferred. Concerning duration of treatment, 4 to 5 days seem adequate for meningococci and 7 days for Haemophilus influenzae and pneumococci. Lastly, the usefulness of adjunctive antiinflammatory treatment is considered. The purpose of this treatment is to lower the risk of cerebral complications and neurosensory impairment. Current data suggest that use of corticosteroids as early as possible may be helpful. Improved understanding of the pathophysiology of pediatric bacterial meningitis has led to other forms of treatment being proposed, but their value remains to be proven.

Modulation of the host's inflammatory response in bacterial meningitis may be beneficial. In this study, the effects of dexamethasone and HWA-138, an analog of pentoxifylline, on CSF cultures and cochlear inflammation in an infant rat model of Haemophilus influenzae type b were studied. Five-day-old infant rats were inoculated once intraperitoneally with 1 x 10(4) to 10 x 10(4) CFU of H. influenzae type b (strain 1406). Twenty-four hours later, infant rats were treated intraperitoneally with one dose of ampicillin (0.1 mg/g of body weight), cefotaxime (0.05 mg/g), or cefuroxime (0.05 mg/g) alone or in combination with one dose of dexamethasone (0.00015 mg/g) or HWA-138 (0.005 mg/g). Twenty-four hours after treatment with cefuroxime plus dexamethasone, animals had a significantly (P less than or equal to 0.04) greater incidence of bacteremia and meningitis (eight of nine animals) than that in animals of the other treatment groups. Overall, dexamethasone was associated with less inflammation (P less than 0.04) of the cochlear nerve compared with that from antibiotic treatment alone. In this model, when suboptimal antimicrobial therapy is administered, anti-inflammatory agents may be beneficial with respect to reducing cochlear inflammation. However, dexamethasone and cefuroxime lead to a higher rate of positive blood and cerebral spinal fluid cultures than cefuroxime alone.

This report emphasizes new clinical information about bacterial meningitis in infants and children. Important elements of diagnosis include examination for the presence of shock and increased intracranial pressure. In such cases, initial treatment should focus on appropriate fluid therapy, administration of oxygen, reduction of intracranial pressure and use of corticosteroids. Currently, antibiotics of choice include ampicillin plus either cefotaxime or ceftriaxone in young infants, and one of these cephalosporins in older patients (beyond 3 months of age). Shorter durations of therapy (5 to 7 days for meningococcus, 7 days for haemophilus and 7-10 days for pneumococcus) are now commonly employed. In many centers, dexamethasone is started before the first dose of antibiotic and continued for 4 days to reduce neurologic and audiologic sequelae. Future trends will include studies of endotoxin neutralizers and non-steroidal anti-inflammatory drugs to reduce further tissue injury in meningitis. Prevention of meningitis is the ultimate goal. Since Haemophilus influenzae vaccination can now begin at 2 months, this approach may bring important results soon.

A previously healthy 25 year old sportsman is reported who developed Corynebacterium xerosis meningitis with coma and seizures after spinal anaesthesia. The adequate therapy (dexamethason, penicillin, ampicillin, mannitol, intensive care, hyperventillation) resulted in a complete recovery. To the authors' knowledge this is the first case of Corynebacterium xerosis meningitis and the first bacterial meningitis reported after spinal anaesthesia in Hungary.
