Numerous guidelines are available to guide empirical antimicrobial therapy (EAT) in acute bacterial meningitis (ABM) patients. We analysed prognosis factors and compliance to the Infectious Diseases Society of America (IDSA) guidelines in ABM patients requiring stay in an intensive care unit (ICU). A 10-year retrospective study, using prospectively collected data, in 82 ABM patients admitted to a 16-bed university-affiliated French ICU was undertaken. Seventeen patients (20.7%) died during ICU stay. Multivariate analysis isolated four factors associated with in-ICU death: alcoholism (P = 0.007), acute kidney injury (P = 0.006), age >60 years (P = 0.006) and ICU admission for neurological failure (P = 0.01). Causative pathogens were isolated for 62 (75.6%) patients, including 29 pneumococci, 14/28 of which were non-susceptible to penicillin. No characteristics, particularly recent hospitalisation and/or antibiotic delivery, was associated with penicillin susceptibility. Compliance to IDSA guidelines was 65%. Non-compliance concerned to be essentially the non-delivery or low dosage of vancomycin. Treatment compatible with IDSA guidelines was associated with a decreased ICU mortality in univariate (61.5% survival vs. 35.3%, P = 0.05) but not in multivariate analysis. In-ICU mortality associated with ABM remains high. Prognosis factors are related to the severity of disease or underlying conditions. Penicillin non-susceptible Streptococcus pneumoniae can occur without any of the usual predisposing factors.

A 37 year old male was admitted with the diagnosis of bacterial meningitis. Pneumococci were seen in the Gram stain of the cerebrospinal fluid. The clinical condition did not suggest severely raised intracranial pressure, there were no localizing signs and symptoms. CSF was turpid, with 20.100/3/mm(3) , mainly polymorphonuclear cells. Tumor necrosis factor alpha in CSp was greatly increased with 813 pg/ml. Parallel to the application of intravenous Penicillin G a CSF filtration was carried out. Within 214 h 225 ml CSF were filtrated through a Pall-filter, using a bidirectional pump. Cell count dropped to 720/3 cells/mm(3) , TNF-alpha to 39 pg/ml. The clinical course was uneventful, on day 12 the patient could be discharged without sequelae. CSF filtration may be a highly effective method to reduce from the CSF pathogenetically important cytokines, such as TNF-alpha, being responsible for intrathecal/meningeal inflammatory processes and triggered by cell-wall components of bacteria, e.g. pneumococci.

Neisseria meningitidis is one of the most crucial causes of bacterial meningitis worldwide. The incidence of meningitis due to N. meningitidis greatly changes from one geographical area to the other: 500,000-1,200,000 invasive meningococcal diseases occur each year, with 50,000-135,000 deaths. Once the diagnosis of bacterial meningitis is made, parenteral antibiotic treatment is started as soon as possible. A preventive treatment can also be proposed for those subjects at risk of exposure. Globally, resistance to antibiotics used in the treatment of prophylaxis of meningococcal disease is relatively rare. Penicillin is becoming less useful in the treatment of invasive meningococcal diseases because meningococcal isolates are increasingly less susceptible to this antibiotic. Meningococcal strains less susceptible to ceftriaxone or ciprofloxacin are rare. In addition, resistance to rifampicin is not a current concern as resistant isolates are rarely reported. In conclusion, the emergence of new meningococcal strains with decreasing susceptibility during the last decade should not be ignored, as this could be a worrying phenomenon in the future and justifies a judicious epidemiological survey on a continuous basis.

Group A streptococcus (GAS) is a rare cause of bacterial meningitis in children and is associated with a high cerebral complication rate. In this case report, we present a 9-year-old girl with GAS meningitis complicated with cerebritis. Clear guidelines about choice of treatment and indications of follow-up by imaging tests are lacking, making GAS meningitis unpredictable and difficult to treat. Eventually, we found 25 paediatric cases of GAS meningitis presented in the literature and reviewed their treatment choices, outcomes and follow-up by imaging tests. Penicillin and ceftriaxone are most preferred for the treatment of GAS meningitis and adding rifampicin to the antibiotic treatment could be of potential benefit. When considering the duration of antibiotic treatment and follow-up by imaging tests, no clear recommendations were found. We found that GAS meningitis is associated with higher mortality and cerebral complication rates compared to other, more common, bacterial causes of meningitis in children. This should alert the clinician to consider imaging tests routinely, even if the patient improves clinically. We advise clinicians to routinely evaluate for possible cerebral complications through magnetic resonance imaging (MRI) scans. When cerebral complications are found, antibiotic treatment should be prolonged and adding rifampicin to the antibiotic regime may be considered.
