In a prospective, randomized study, moxalactam in 44 children was compared with ampicillin or chloramphenicol in 47 children for the treatment of Haemophilus influenzae type b meningitis. Both groups were comparable in terms of clinical and laboratory findings at admission. The hospital course, neurologic sequelae including deafness, and number of deaths were the same for both groups. The incidence of adverse reactions also was the same except that diarrhea and thrombocytosis occurred significantly (P less than or equal to 0.04) more frequently in children given moxalactam. Moxalactam was equivalent to ampicillin or chloramphenicol in the treatment of H. influenzae type b meningitis in children.

As part of a prospective study of acute bacterial meningitis in children, we studied for five years the hearing of 185 infants and children who had acute bacterial meningitis when they were more than one month of age. Nineteen (10.3 per cent) of the patients had persistent bilateral or unilateral sensorineural hearing loss. The incidence of hearing loss as determined by electric-response audiometry and conventional tests was 31 per cent with Streptococcus pneumoniae, 10.5 per cent with Neisseria meningitidis, and 6 per cent with Hemophilus influenzae infections. Transient conductive hearing impairment was found in 16 per cent of the sample, but in no case was there apparent improvement in a sensorineural deficit over time. The site of disease resulting in impaired hearing cannot be stated with certainty, but involvement of the inner ear or auditory nerve was suspected. The number of days of illness (symptoms) before hospitalization and institution of antibacterial treatment was not correlated with the development of sensorineural deafness.

This study was done to analyze the epidemiology of invasive Haemophilus influenzae disease in Bochum city area. Forty-eight children with invasive Haemophilus influenzae infections were treated at the University Children's Hospital in Bochum during the study period from January 1971 to June 1992. Clinical manifestations included meningitis (n = 34), epiglottitis (n = 8), pneumonia (n = 2), bacteremia (n = 2), cellulitis (n = 1) and osteomyelitis (n = 1). The overall yearly incidence rate for all invasive Haemophilus influenzae infections was 13 per 100,000 children younger than five years of age, with a marked increase in the last six years. Haemophilus influenzae meningitis showed no significant change during the study period with an overall yearly incidence of 9 per 100,000 children younger than five years. Twenty-eight cases (58%) of all invasive Haemophilus influenzae infections occurred in patients under two years of age and five cases (10%) were younger than six months. Invasive Haemophilus influenzae disease showed no seasonal prevalence. All isolates were susceptible to ampicillin. No deaths occurred, but severe bilateral deafness resulted in one patient with meningitis. Prospective epidemiologic studies are needed to estimate clinical efficacy of the Haemophilus influenzae type b immunization program in Germany.

The report concerns findings for brainstem auditory evoked potentials (BAEPs) recorded in 116 children, aged between a few days and 7 years, having suffered from bacterial meningitis. 26% of cases occurred between birth and 6 months, 55% between 6 months and 2 years, and 19% after 2 years of age. Hemophilus was the most common bacteria (49%), followed by Pneumococcus (22%) and Meningococcus (15%). Neurological complications were found in 30% of the meningitis cases and accounted for 85% of all complications found. 29% of BAEPs were abnormal, of which 47% revealed transmission, 32% endocochlear and 21% retrocochlear impairment. Transmission impairment mainly occurred before the age of 2 years (88%), most frequently in meningococcus meningitis cases (44%), and independently of neurological complications. Retrocochlear impairment was found in association with neurological complications in 71% of cases. Endocochlear BAEP damage was found in 9.5% of cases, half of which were bilateral and total, representing cophosis: it was found at all ages, and without any particular associated neurological complication. Hemophilus was the commonest bacterial agent in endocochlear cases overall, with Pneumococcus underlying 50% of cophosis cases. The study shows BAEP recording in association with a clinical ear examination is useful following childhood bacterial meningitis, screening for definitive endocochlear and deafness, distinguishing total from partial hearing-loss and indicating suitable treatment.

We abstracted the results of all English language reports of the outcomes of bacterial meningitis published after 1955. We used hierarchical Bayesian meta-analysis to determine the overall and organism-specific frequencies of death and persistent neurologic sequelae in children 2 months to 19 years of age. A total of 4920 children with acute bacterial meningitis were included in 45 reports that met the inclusion criteria. Children described in the 19 reports of prospectively enrolled cohorts from developed countries had lower mortality (4.8% vs. 8.1%) and were more likely to have no sequelae (82.5% vs. 73.9%). In these 19 studies 1602 children were evaluated for at least 1 sequela after hospital discharge. The mean probabilities of these sequelae were: deafness, 10.5%; bilateral severe or profound deafness, 5.1%; mental retardation, 4.2%; spasticity and/or paresis, 3.5%; seizure disorder, 4.2%; and no detectable sequelae, 83.6%. Mean probabilities of outcomes varied significantly by etiologic bacteria, e.g. mortality: Haemophilus influenzae, 3.8%; Neisseria meningitis, 7.5%; Streptococcus pneumoniae, 15.3%.

Steroid therapy, in combination with antibiotics for bacterial meningitis in paediatric patients remains controversial. Steroids, and primarily dexamethasone a very potent anti-inflammatory agent, regulate the liberation of various cytokines and inflammatory mediators such as prostaglandins, released during bacterial meningitis and leading to long term complications. Several clinical trials studying infants and children with bacterial meningitis due to Haemophilus influenzae have evaluated the beneficial effects of the administration of dexamethasone at the onset of antibiotherapy and demonstrated that dexamethasone reduced the risk of acquired sensorineural deafness (bilateral moderate or more severe hearing loss) and the incidence of neurological sequelae. Limited information is available for the other bacterial meningitis, although meningococcal meningitis will become more frequent with the use of effective anti-Haemophilus vaccines. In addition some Streptococcus pneumoniae are now resistant to third generation cephalosporins and the use of dexamethasone in that case may be at risk. Finally, no evidence is available for an effective role for dexamethasone in neonatal bacterial meningitis, although it is quite often administered in that age group.

Haemophilus influenzae is an infrequent etiologic agent of bacterial meningitis in adult patients. In the last 12 years, it was the cause in 12 out of 238 cases (5.0%) of acute bacterial meningitis in adults. There were 5 men and 7 women with a mean age (SD) of 45.4 (16) years (range: 18-68 years). Seven patients (60%) had a communication between subarachnoid space and skin surface or mucosal cavities, and five (41.7%) had otitis or sinusitis. Most of the strains (9/12) were serotype b. Only one patient (8.3%) developed severe neurologic and extra-neurologic complications, and was the one who died. One of the survivors (9.1%) had partial deafness. H. influenzae is not a negligible cause of bacterial meningitis in adults. Moreover, its detection has been increasing in the last years. Patients with a cerebrospinal fluid leak, otitis or sinusitis are at high risk. The outcome is usually favorable if an early adequate therapy is given.

Between July 1988 and June 1998, 22 pediatric patients without underlying diseases were diagnosed as bacteremia caused by community-acquired infection in Asahikawa Kosei Hospital. The age range of the patients was from 7 days to 4 years. Their diseases were meningitis in 6, urinary tract infection in 6, respiratory tract infection in 4, skin infection in 2, and unknown origin in 4. The causative organisms were Escherichia coli in 7, Haemophilus influenzae in 4, Streptococcus pneumoniae in 4, Staphylococcus aureus in 2, Streptococcus pyogenes in 1, Streptococcus agalactiae in 1, Listeria monocytogenes in 1, Moraxella catarrhalis in 1, and Rahnella aquatilis in 1. Though 21 patients recovered with antimicrobial treatment, only one patient with H. influenzae meningitis had lateral deafness and paresis in the lower limbs as sequelae.

The Health Council of the Netherlands (Gezondheidsraad) assessed the vaccination of infants against both group-C meningococci and pneumococci in terms of general criteria and basic principles for inclusion in the national vaccination programme. Vaccination against meningococci C in the Netherlands is expected to prevent about 300 cases of meningococcal disease (meningitis or sepsis), 22 deaths and 12 cases of severe lasting problems (neurological problems or amputations) per year. Vaccination against pneumococci may prevent about 100 cases of meningitis or sepsis, 3200 cases of pneumonia, 36,000 cases of acute otitis media, 11 deaths, 11 cases of severe permanent damage (neurological problems, deafness) per year. The Health Council advised implementing vaccination against group-C meningococci as soon as possible, through 2 injections at the ages of 5 and 6 months or through 1 injection shortly after the child's first birthday, and to carry out a catch-up programme for all children and adolescents up to and including 18 years of age. The council also advised starting a vaccination programme against pneumococci, at ages 2, 3 and 4 months, as soon as the current vaccinations against diphtheria, tetanus, pertussis and polio and against Haemophilus influenzae type b are combined into 1 injection (in 2002 or 2003). In view of the concentration of pneumococci disease in the first years of life, a catch-up programme is not indicated in this case. The Health Council emphasised the importance of microbiological and clinical monitoring of potential adverse effects and of public education programmes. The cost of vaccination against group-C meningococci is comparable to that of other accepted programmes for primary prevention. Compared to other programmes and at the current vaccine price, the cost of vaccination against pneumococci is high.

Acute respiratory infection (ARI) is the most common infectious cause of childhood death in Africa. Most deaths from ARI are caused by bacteria, including Haemophilus influenzae type b (Hib). Hib is also the most common bacterial cause of meningitis, except in those areas with outbreaks of meningococcal disease. Up to 40% of infants with meningitis die, and many of the survivors have permanent deafness and brain damage. Until recently, however, early diagnosis and treatment was the only defence against these infections. The newly developed Hib conjugate vaccines have been shown to be effective against Hib meningitis and pneumonia, and are now routinely used in infants in more than 25 countries around the world. A study of the efficacy of the vaccine in The Gambia's Western Region in 1993-95 showed that it was 95% effective in preventing meningitis and bloodstream infection, and 100% effective in preventing pneumonia. Hib vaccine was introduced this year in The Gambia as a routine immunization for children, to be given in the same injection as DTP at 2, 3, and 4 months of age. A 1-year study is underway to evaluate the impact of the vaccine upon disease. Trials are now underway for new pneumococcal and meningococcal vaccines which may be ready for wider use within 5-10 years.
