The aim of the present study was to evaluate the potential role of cerebrospinal fluid soluble urokinase receptor (suPAR) level, infection and age as risk factors for fatal outcome in patients suspected of having meningitis and/or bacteraemia on admission to hospital. A total of 545 cerebrospinal fluid samples from patients with clinically suspected meningitis were sent to the Hellenic National Meningitis Reference Laboratory. Ten of 545 (1.83%) patients died. Analysis by receiver operating characteristics (ROC) curve revealed that both suPAR and age were significant for prediction of fatal outcome. Patients with levels of suPAR above the cut-off values and age ≥ 51 years, or patients in which either Neisseria meningitis or Streptococcus pneumoniae were detected were categorized as high risk patients. The combination of the above three predictors (suPAR, age and infectious agent) in a logistic regression model with outcome of infection as the dependent variable yielded an overall odds ratio (OR = 85.7, 95% CI 10.6-690.2) with both sensitivity and specificity being equal to the value of 0.9. In conclusion, suPAR, age and type of infection have an additive effect in predicting mortality among patients suspected of meningitis.
