Community-acquired bacterial meningitis in cirrhotic patients.

The Hospital Universitari de Bellvitge (Barcelona, Spain) records all cases of bacterial meningitis in a 120-variable database. The characteristics of bacterial meningitis in cirrhotic patients are not well-known, and all cases of community-acquired bacterial meningitis occurring in cirrhotic patients were therefore identified. During 1977-2002, there were 602 episodes of community-acquired bacterial meningitis in adults, of which 29 (4.8%) occurred in cirrhotic patients. Compared to non-cirrhotic patients, there were significant differences in: duration of disease for >4 days at the time of diagnosis; absence of nuchal rigidity; certain aetiologies, e.g., Escherichia coli and Listeria monocytogenes; renal and liver function impairment; relapse of fever; and incidence of relapse and mortality. Overall, bacterial meningitis in cirrhotic patients was associated with a high mortality rate and a large number of complications. A high index of suspicion is necessary because of the frequent absence of meningeal signs. In addition to the classic meningeal pathogens, other aetiologies, including E. coli and L. monocytogenes, should be considered when prescribing empirical therapy.
