Acinetobacter meningitis – a diagnostic pitfall. Intraventricular antimicrobial therapy in postneurosurgical Gram-negative bacillary meningitis or ventriculitis: Infect Control Hosp Epidemiol.
Management of meningitis due to antibiotic-resistant Acinetobacter species
Semin Respir Crit Care Med. Additionally, we would recommend that antimicrobial therapy be combined with removal of all neurosurgical hardware to maximise the chances of cure of this infection. In a review of six studies comprising adults with community-acquired bacterial meningitis, just 0.
Risk factors Acinetobacter meningitis typically occurs following neurosurgery table 1. Both imipenem and meropenem have been used in the treatment of acinetobacter meningitis. Author manuscript; available in PMC Oct Cure of post-traumatic recurrent multiresistant Gram-negative rod meningitis with intraventricular colistin.
The pharmacokinetic parameter that best correlates with a positive outcome for serious infections when gentamicin is administered intravenously, is the ratio of peak serum concentration C max to MIC optimally the ratio should be greater than ten.
IDSA guidelines for management of bacterial meningitis reserve ciprofloxacin for patients who have not responded to, or cannot receive, alternate antimicrobial therapy.
There is only one clinical case report of use of tigecycline in the treatment of acinetobacter meningitis, 17 and no cases in patients dsoe meningitis in which tigecycline CSF concentrations have been measured. Infectious Diseases Society of America guidelines for therapy of postneurosurgical meningitis recommend either ceftazidime or cefepime as empirical coverage against Gram-negative pathogens.
Ghoneim AT, Halaka A. Recommendations for antimicrobial therapy intdaventricular patients with acinetobacter meningitis, by clinical setting. Nonconvulsive status epilepticus due to cefepime in a patient with normal renal function.
Fluoroquinolones may sometimes be active against Acinetobacter spp, with levofloxacin tending to have lower MICs than ciprofloxacin. Using intrathecal colistin for multidrug resistant shunt infection.
Thus, these antibiotics are poor options for suspected acinetobacter meningitis. Acinetobacter meningitis typically occurs following neurosurgery table 1. Pharmacokinetic optimisation of the treatment of bacterial central nervous system infections.

At the present time there are insufficient data to intraventrichlar that combination therapy with an aminoglycoside reduces the risk of emergence of resistance to carbapenems. Cases lntraventricular pseudomeningitis with acinetobacter ie, CSF is culture positive for acinetobacter in the absence of clinical and laboratory features of meningitis have been well described.
This high dose resulted in a peak CSF concentration of 2. Global challenge of multidrug-resistant Acinetobacter baumannii. A retrospective study of central nervous system shunt infections diagnosed in a university hospital during a 4-year period.
An increasing threat in hospitals: The relevant studies were retrieved through searches of PubMed January, to July, and references cited in relevant articles. Final antimicrobial therapy with survival rate.
Combination with an intraventricularly administered antibiotic plus removal of infected neurosurgical hardware appears the therapeutic strategy most likely to succeed in this situation. Gram-negative bacillary meningitis after cranial surgery or trauma in adults.
Given these reports, and uncertainty surrounding the penetration of colistin methanesulphonate and the formed colistin into the CSF, it appears that use of intravenous colistin methanesulphonate alone for management of acinetobacter meningitis may be inadvisable. Combined colistin odse rifampicin therapy for carbapenem-resistant Acinetobacter baumannii infections: Intraventricular or intrathecal use of polymyxins in patients with Gram-negative meningitis: Toxicity potentially related to local administration of polymyxins was noted in 17 of 60 patients—in 12 of these meningeal irritation was reported.
Polymyxin B for injection package insert. Unfortunately, limited development of new antibiotics plus the growing threat of multidrug-resistant acinetobacter is likely to increase the problems posed by acinetobacter meningitis in the future.
A review of episodes.

The caveat to this statement is that while a small number of studies have assessed CSF amikacin concentrations in adults,these do not give enough information to determine true peak concentrations, and therefore the likelihood of meeting pharmacodynamic targets. The recommended dosage in IDSA guidelines for polymyxin B administered by the intraventricular route is 5 mg daily in adults and 2 mg daily in children.
