The relation of neuraminidase to morbidity and mortality was examined in patients with Haemophilus influenzae, meningococcal, and pneumococcal meningitis. Ten strains of H. influenzae and eight strains of meningococci from infected cerebrospinal fluid (CSF) did not elaborate neuraminidase. Each of 27 strains of pneumococci from infected CSF elaborated both neuraminidase and N-acetylneuraminic acid (NANA) aldolase. There was no correlation between amount of neuraminidase secreted in vitro and survival of patients. Values for free and total NANA concentrations were derived from admission CSF samples of 63 patients with meningitis; 18 patients infected with Neisseria meningitidis, 10 with H. influenzae and 35 with Diplococcus pneumoniae. Mean values for total NANA were elevated in each type of bacterial meningitis; however, abnormal concentrations of free CSF NANA were detected only in 17 patients with pneumococcal meningitis. 11 of 18 patients with pneumococcal meningitis showing normal free CSF NANA concentrations were cured, whereas only 4 patients with abnormal free NANA levels survived without residua. Both coma and bacteremia occurred significantly more often among patients with elevated concentrations of free CSF NANA. The association of elevated concentrations of free CSF NANA with coma and with an adverse prognosis suggested that neuraminidase may be a factor in the pathogenesis of penumococcal meningitis.

One hundred and sixty cases of acute bacterial meningitis were treated with cefotaxime. Patients were between 9 days and 79 years old: 7 new borns, 37 infants, 43 children, 19 adolescents and 54 adults. Fifty-eight patients (36%) were in coma when admitted. Aetiology was determined in 110 patients (68.8%): Neisseria meningitidis in 42, Streptococcus pneumoniae in 36, Haemophilus influenzae in 16, Salmonella spp. in 7, Staphylococcus aureus in 2, Enterobacter spp. in 2 and Haemophilus parainfluenzae, pseudomonas aeruginosa, Escherichia coli, Citrobacter freundii and Klebsiella pneumoniae in one patient each. All isolates were sensitive to cefotaxime, with MIC's for 26 strains ranging from 0.01 to 0.50 mg/l. One hundred and fifty-six of the 160 patients were treated with cefotaxime alone and the four others with cefotaxime in association with an aminoglycoside in three and rifampicin in one. Cefotaxime was administered by intravenous infusion, in a daily dose 100 to 300 mg/kg. Duration of treatment ranged from 8 days to 6 weeks, with a mean of 15 days. One hundred and forty-nine patients (93.1%) were cured, two after a relapse. Three patients had sequelae. Most (88.5%) had sterile CSF within 72 h after starting treatment. Eleven patients (6.9%) died, eight within the first 48 h. The only side-effects observed were mild transient eosinophilia in some patients and rash and leukopenia in 2 each. The study demonstrates that cefotaxime is effective in the treatment of acute bacterial meningitis.

A retrospective record study of six cases of meningitis caused by group A beta-hemolytic Streptococcus is presented. Associated findings included otitis media, pharyngitis, and erysipelas. All patients survived their infections despite major complications including seizures, shock, coma, renal failure, and hepatitis. Two patients had neurologic sequelae. Group A Streptococcus causes a severe form of bacterial meningitis in apparently healthy children.

During the years 1966-1976, 875 patients with bacterial meningitis were treated at the Department of Infectious Diseases, Rigshospitalet, Denmark. In late 1979 and early 1980 a survey by questionnaire was conducted among survivors concerning the impact of the disease. Replies were received from 667 patients (96.4 per cent). The most common complaints after meningitis were headache (32 per cent) inability to concentrate (31 per cent), altered working capability (33 per cent) and loss of memory (24 per cent). Approximately 20 per cent suffered from impaired hearing, visual disturbances and dizziness. Five per cent had convulsions. Each questionnaire was evaluated for sequelae, and when present these were rated as mild, medium or severe. One-third of the patients had sequelae and in 6 per cent these were severe. Sequelae were most commonly associated with drowsiness, coma, agitation and confusion on admission to hospital.

Haemophilus influenzae type b (HIb) is the most common cause of bacterial meningitis in children with a mortality rate ranging from 1.6% to 14%. Most patients have a 2-3 day history of symptoms prior to admission. A few have fulminating disease with rapid neurological deterioration. Review of 191 cases of HIb meningitis revealed a mortality rate of 2.1% but all who died had fulminating meningitis (FM). Four of six patients with FM died. FM patients had symptoms for less than 24 hours before rapid neurological deterioration with increased ICP, seizures, coma and/or respiratory arrest. Review of 10 FM cases revealed that on admission, 5 had hypotension, 3 had thrombocytopenia, and 8 had coma. Typical CSF changes were seen in only 7. All fatal cases died within 24 hours. Brain swelling and tonsillar herniation were found at autopsy. SDS-PAGE outer membrane protein subtyping did not show one "killer strain". Animal and autopsy data suggest that diminished CSF outflow and cerebral edema contribute to increased ICP. To improve survival of FM patients, initial treatment must (1) decrease ICP below levels impairing cerebral perfusion, (2) maintain adequate ventilation and blood pressure, and include (3) LP when stable, (4) antibiotics, and (5) close monitoring. Utilizing these principles, two FM patients survived without major sequelae.

A parenteral formulation of rifampicin (Rimactan i.v., Ciba-Geigy, Basel, Switzerland) was administered to 237 critically ill or comatose patients, or patients with gastro-intestinal or absorption problems. There were 160 patients suffering from tuberculosis, 77 suffering from non-tuberculous (non-tb) infections including 30 cases of sepsis, 8 cases of bacterial meningitis and/or cerebral abscess and 9 patients with Legionnaires' disease. The usual daily dose of rifampicin was 450-600 mg, administered in most cases by i.v. bolus (122 cases) or i.v. drip infusion (79 cases) for a period of 1-113 days. Rifampicin was in all cases combined with one or more antimicrobial drug(s). The physicians considered the therapy as successful when the treatment with oral rifampicin could be instituted soon after parenteral administration or when the patients markedly improved their clinical condition. Of a total of 123 tuberculous patients for whom assessment of efficacy was possible, 100 (81.3%) showed favourable clinical results. Of 40 non-tb patients who could be analysed for clinical progress, 32 (80.0%) had a favourable outcome. Special attention should be drawn to the 11 patients with proven staphylococcal infections, of whom 10 were cured clinically and/or bacteriologically. Thrombophlebitis occurred in 10 out of the 237 (4.2%) patients, almost always in patients who were treated for more than 30 days. Systemic unwanted effects occurred in 14 (5.9%); the relationship to the treatment was not always established. Treatment was withdrawn due to unwanted effects in 5 (2.1%) of the 237 patients. Taking into account the severe, life-threatening infections reported, the results suggest that i.v. rifampicin is useful and in some critically ill patients even life-saving. Tolerability was good, even in long-term i.v. administration, although there seems to be the possibility that thrombophlebitis might develop if treatment is continued over 30 days.

The clinical and laboratory characteristics of eleven cases of bacterial meningitis due to Salmonella, are reviewed. Meningitis was more common in children under the age of 13 months. In younger children the symptoms and neurological signs were not evident. Convulsive disorders and neurological coma were the most frequent complications in 4 and 5 cases respectively. The mortality ratio was high, 36% (4 patients) and the neurological sequelae were very important: two patients presented spastic paralytic alterations and other two had hydrocephalia. The main findings in the cerebral spinal fluid were: increased leukocytes and proteins with low glucose determinations; comparing with other purulent meningitis, mononuclear cells were predominant over polymorphonuclear cells in 7 cases (64%). Salmonella was isolated in all cases; Salmonella typhi was recovered in 3 cases; one had group "C" Salmonella and 7 cases Salmonella group "B". These cases were treated with either chloramphenicol or ampicillin.

Children with bacterial meningitis often have a full blood count (FBC) measured urgently on admission. We investigated whether urgent FBC gave results that aided immediate management or predicted outcome in children with meningitis. FBCs were measured on admission during 190 episodes of bacterial meningitis in children admitted between 1984 and 1991. Significant anaemia was found in seven children, but immediate transfusion was only necessary in the three subjects who were in the Paediatric Intensive Care Unit (PICU). A white blood count of less than 5 x 10(9) L-1 was significantly associated with death (P < 0.02), but a Glasgow Coma Score of less than 8 predicted death more accurately (positive predictive value of 40%). FBC yielded immediately useful information only in the 15% of children who were admitted to PICU. Conscious level was a better predictor of outcome than FBC. We recommend that urgent FBC should be performed in children with meningitis admitted to a PICU; in other children with meningitis FBC can be analysed during normal laboratory hours.

Bacterial meningitis is still an important cause of death and/or persistent nervous system damage in children living in developing countries. The aim of the study was to evaluate the effectiveness of steroids in reducing mortality and neurologic sequelae in children affected by bacterial meningitis within the context of a developing country (Mozambique), where the case-fatality rate of this disease is over 30 per cent. Seventy children with bacterial meningitis were randomized to receive either conventional antibiotic therapy or antibiotic therapy plus dexamethasone. On hospital admission there were no statistically significant differences between the two groups with regard to clinical and laboratoristic features. When dexamethasone was used early mortality, within 24 h, was significantly reduced (1/34 v. 8/36, P < 0.05). Total mortality among steroid treated patients, including those who were comatose on admission, was also reduced even if the difference did not reach statistical significance. A favourable trend in terms of fewer serious neurologic abnormalities was also observed among survivors in the steroid treated patients (5/26 v. 7/24). Fever and CSF abnormalities also disappeared more rapidly in patients receiving dexamethasone (P < 0.05). This study showed that the beneficial effect of adjunctive steroid therapy in children with bacterial meningitis can be even more important in areas where the case-fatality rate of this disease is still very high.
