Interleukin-1 (IL-1) is the key initiator of host responses to infection. We describe here the lipopolysaccharide-(LPS) (20 micrograms/ml) stimulated IL-1 production of peripheral blood monocytes in 2 children with Haemophilus influenzae meningitis. We found a depressed IL-1 production at the acute stage of the infection when the meningitis was most active with return to normal coinciding with clinical recovery. These results show an inverse correlation with acute phase reactants and IL-1 production. Normalization of IL-1 production seems to be a good prognostic sign in bacterial meningitis.

In prospective studies, tumor necrosis factor (TNF alpha) was detected in cerebrospinal fluid (CSF) of 33 of 38 children with bacterial meningitis (BM) but in none of 15 with viral meningitis/encephalitis (P less than .001). BM CSF TNF alpha (less than 35 to greater than 25,500 pg/ml) correlated with CSF bacterial density (P less than .01), CSF protein (P less than .001), endotoxin (LPS) in gram-negative disease (P less than .01), and consecutive febrile hospital days (P less than .001); initial CSF TNF alpha greater than 1000 pg/ml was associated with seizures (P less than .05). Only 5 children with BM (13%) had detectable plasma TNF alpha activity on admission. A higher proportion who died had detectable plasma TNF alpha activity compared with survivors (3/4 vs. 2/34, P less than .005). Platelet-activating factor (PAF) in CSF was higher in 19 children with Haemophilus influenzae meningitis than in 17 controls (P less than .01) and correlated with bacterial density (P less than .01), CSF LPS (P less than .01), CSF TNF alpha levels (P less than .01), and the Herson-Todd severity score (P less than .01). Elevated CSF TNF alpha and PAF are often present in children with BM and are associated with seizures and severity of disease. Detectable CSF TNF alpha appears to distinguish BM from viral meningitis.

Antimicrobial treatment of bacterial meningitis should be done by antibiotic to which the causative agent is susceptible, which attained serum levels ensure adequate penetration across the blood-brain barrier and which bactericidal levels in cerebrospinal fluid are achieved. A total number of 61 child in age from 2 months to 7 years with bacteriologically proved Haemophilus influenzae meningitis was included in the study. The possibility and usefulness of application of various antibiotics used in the treatment of this disease as well as the results attained have been discussed. A total number of 40 patients was treated with only one antibiotic (ampicillin 6, chloramphenicol 6, cefuroxime 3, cefotaxime 18, ceftazidime 7) and 21 patients were treated with combinations of antibiotics (ampicillin + chloramphenicol 14, cefuroxime + chloramphenicol 7). The causative agent was susceptible to the applied antibiotic in all cases. The agent susceptibility was estimated qualitatively by disk diffusion method and quantitatively by methods of minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC). Even 31.1% of H. influenzae strains were resistant to ampicillin. Penetration across the blood-brain barrier was monitored by estimation of antibiotic concentration in sera and liquor. Antibiotic concentrations in liquor attained the bactericidal levels. The same good results were attained with any of single applied antibiotics. In cases of delayed initiation of the antimicrobial therapy the appearance of neurological complications was more frequent, the outcome of the disease was worse and the duration of treatment was longer.(ABSTRACT TRUNCATED AT 250 WORDS)

Nine hundred seventy cases of childhood bacterial meningitis treated at 107 institutions in Japan from 1979 through 1984 were studied using questionnaire. The number of cases that underwent antimicrobial monotherapy remained nearly constant during the study period, but cases of therapies with beta-lactam combined with aminoglycosides (AGs) decreased in number and a gradual increase in the use of beta-lactam combined with non-AGs antibiotics including beta-lactam (Non AGs) was observed. A trend showing decrease in case fatality rate (CFR) was observed except that CFR for Gram-positive bacterial infections treated with beta-lactam + AGs remained at a same level. Cases treated with antibiotics were classified into 3 groups according to major etiological pathogens. Cases with Staphylococcus aureus gave a poor prognosis, among 27 total cases, CFR was 28.6% (2/7) with monotherapy, 50.0% (6/12) with beta-lactam + AGs and 37.5% (3/8) with beta-lactam + Non AGs (P less than 0.1). Among 100 cases of group B Streptococcus (GBS), CFR was 20.0% as a whole, 17.3% (9/52) for monotherapy and 34.5% (10/29) for beta-lactam + AGs (P less than 0.1). Among 198 cases of Streptococcus pneumoniae, CFR was 12.1% as a whole, and was 12.3% (18/146) with monotherapy. CFR for the cases treated with beta-lactam + AGs was 20.8% (5/24) and with beta-lactam + Non AGs was 3.6% (1/28) (P less than 0.1). CFR for 292 cases of Haemophilus influenzae meningitis was fairly low, and was 6.1% (9/148) with monotherapy, 7.4% (5/68) with beta-lactam + AGs and 3.9% (3/76) with beta-lactam + Non AGs, thus very slight differences were observed among the 3 groups of treatment. Among 111 cases of Escherichia coli, monotherapy and beta-lactam + Non AGs gave 6.5% (2/31) CFR, and 5.6% (1/18) CFR, respectively, whereas beta-lactam + AGs showed CFR of 19.4% (12/62), demonstrating a significant difference tendency (P less than 0.1). Similar tendencies were observed in the cases of Listeria monocytogenes, Proteus mirabilis, Pseudomonas aeruginosa and Enterococcus faecalis. Contrary to the high CFR observed with the beta-lactam + AGs treatment, significantly low CFR was frequently obtained in cases treated with a combination of penicillins with cephalosporins including latamoxef or beta-lactam with chloramphenicol. Infections with GBS, E. coli, and P. mirabilis occurred largely in the age between 0 to 6 months and CFR was especially high in the very young.(ABSTRACT TRUNCATED AT 400 WORDS)

The presence of viral infection was evaluated in 160 children older than three months with bacterial meningitis who were admitted to Children's Medical Center or Parkland Memorial Hospital, Dallas, TX, between October 1979 and March 1982. Results were compared with a single serologic specimen in 138 children without meningitis. A recent history of upper respiratory infection was obtained from 60% of patients, including 10/13 with pneumococcal, 9/16 with meningococcal, and 77/131 with Haemophilus influenzae meningitis. Viral infection was documented by serologic response (23.8%) or viral isolation (13.2%) in 63/160 (40%) of patients with meningitis. There were 23 positive cultures (one patient with both adenovirus and respiratory syncytial virus). Picornaviruses, including two rhinoviruses, were isolated from six of the 24 subjects without meningitis who had viral cultures. There were 69 serologic conversions in meningitis patients, with 12 patients converting to two organisms and four patients converting to three organisms. Viral diagnoses included: adenovirus, 32 children; respiratory syncytial virus, 14; influenza A, 8; influenza B, 4; parainfluenza (1, 2, and 3), 12; picornaviruses, 9; herpes simplex virus, 1; and cytomegalovirus, 1. Additionally, 6/15 seroconverted to Mycoplasma pneumoniae. The acute geometric mean serum antibody titers of meningitis patients were lower than those of the comparison group for adenovirus (3.5 vs. 6.6, p less than or equal to 0.001) and influenza B (1.2 vs. 1.6, p less than or equal to 0.05). Twenty nine of 131 patients with H. influenzae had evidence of recent adenovirus infection. Primary infection with adenoviruses and possibly influenza B or mycoplasma precedes development of bacterial meningitis in some patients and may be a predisposing factor.

Of 207 patients with acute bacterial meningitis previously reported by Dodge and Swartz, seizures occurred in 56 (27%). Most seizures began on the first or second day, and most stopped within two days. Seizures occurred most often at the extremes of life. Age-adjusted seizure frequency was greater with Hemophilus influenzae meningitis than with Streptococcus pneumoniae or Neisseria meningitidis. When seizures complicated bacterial meningitis, age-corrected mortality increased from 24% to 38%. Though seizures after recovery were infrequent (2.7% of cases), recurrences were five times more frequent in patients who convulsed acutely than in those who did not. When focal seizures accompanied focal pathology (extracranial or intracranial), the seizures were usually not lateralized to the opposite side of the body. Of factors of potential importance in causation of seizures, fever was the most important risk factor regardless of patient age.

Serum C-reactive protein (CRP) was measured nephelometrically or turbidimetrically for rapid differential diagnosis of sixteen bacterial and fifteen viral infections of the central nervous system in patients aged from 2 weeks to 49 years. On hospital admission CRP levels were far above the upper limit of normal (19 mg/l) in all patients with bacterial meningitis, regardless of the duration of illness, the age of the patient, the bacterium involved, fever, the erythrocyte sedimentation rate, or the cerebrospinal-fluid cell count. In contrast, a slight rise in CRP level was seen in only one case of viral meningitis. CRP was useful also in monitoring the clinical course of the illnesses and in the detection of subdural effusion in one patient with Haemophilus influenzae meningitis and of otitis media in another patient with coxsackie B meningitis. If no complications developed, CRP levels returned to normal within 7 days in the bacterial meningitis group. The rapid measurement of CRP levels is of importance and should be used more often in clinical practice.

Among 809 patients with bacterial meningitis persistent pleocytosis greater than 60 white blood, cells/mm3, after 10 days or more of therapy, was found in 25 patients and persistent hypercervicospinal fluid proteins greater than 70 mg/dl in 24. In 14 patients there was an association of these disturbances. All cases, except one, were adequately treated. Persistent pleocytosis and hyper-cervicospinal fluid proteins, uncommon inmeningococcal meningitis, were frequent in pneumococcal and more frequent in Haemophilus influenzae meningitis. In pneumococcal and Haemophilus influenzae meningitis the incidence of neurologic sequelae was greater in patients with persistent pleocytosis and hyper-cervicospinal fluid proteins than without them. In adequately treated patients, persistent pleocytosis or hyper-cervicospinal fluid proteins alone cannot be used as an indication of prolonging or changing therapy of bacterial meningitis.

Bacterial meningitis is a major cause of sensorineural hearing loss during childhood. This study compared the efficacy of auditory brain-stem evoked response (ABER) testing with conventional conditioned orienting response (COR) testing in the early diagnosis of postmeningitic deafness in 34 infants younger than 2 years of age, with a diagnosis of Hemophilus influenzae meningitis. In most of the children (62%), results of the two tests were in agreement. The use of ABER testing appeared to be more effective than COR audiometry for the testing of infants younger than 6 months of age, for older children with perceptual handicaps, and for the identification of small children with unilateral hearing loss.
