Abstract:
OBJECTIVE To characterize clinical feature,frequency of isolation and antimicrobial susceptibility of bacterial pathogens isolated from patients with healthcare-associated bacterial meningitis(HABM).METHODS We review the charts of all patients in whom the diagnosis was based on(national) diagnostic criteria of healthcare-(associated) infections at Huashan Hospital from 1995 through 2004.The pathogens were routinely isolated,(identified) and susceptibilities against antimicrobial agents were determined by Kirby-Bauer methods.RESULTS During the 10-year study period,109 patients were treated for 120 episodes of HABM.Most of patients had a(history) of recent and remote neurosurgery.Fever was present in all patients,while nuchal rigidity and decrease consciousness were present in less than half of all patients.CSF opening(pressure,) white blood cell count and(protein) were elevated with predominance of neutrophils.A total of 120 strains were isolated from CSF specimen,Gram-positive bacteria and Gram-negative bacilli were accounted for 35.8% and(64.2%) of all isolates,respectively.Acinetobacter spp(24.2%),coagulase-negative staphylococci(22.5%),Klebsiella pneumoniae(12.5%),Pseudomonas aeruginosa(10%),Enterobacter cloacae(8.3%) and Staphylococcus aureas(7.5%) were the 6 most frequent isolates and resistance to the first line antibiotics was common among all pathogens isolated.(CONCLUSIONS) The most common risk factor for HABM is neurosurgery.Gram-negative bacilli and staphylococci are important causes of HABM,resistance to the first line antibiotics is common among all pathogens isolated.
