| Summary: | ABSTRACT Introduction Nosocomial infection of the central nervous system (NI-CNS) is a serious complication in neurocritical patients that leads to deterioration of patient’s condition, worsening of outcomes and increased cost of treatment. The timely diagnosis of NI-CNS is a relevant problem and the search for new reliable markers of NI-CNS is an important issue.MATERIAL AND METHODS The prospective observational study consisted of two parts. The aim of the frst part was to defne normal ranges of cerebral spinal presepsin (CSF PSP). The aim of the second part was investigation of CSF PSP in neurocritical patients. We studied CSF sampling obtained during spinal anesthesia for elective urologic surgery in order to defne the normal CSF PSP. The following data was collected in neurocritical patients: CSF cell count, glucose, lactate, PSP, microbiological tests, polymerase chain reaction (PCR), when it was possible. Blood tests included complete blood count, C-reactive protein (CRP), procalcitonin (PCT), PSP. IBM SPSS Statistics (version 23.0) was used for statistical analysis.RESULTS Fifteen CSF samplings were obtained for investigation of normal CSF PSP ranges, which was 50–100 pg/ml. Nineteen neurocritical patients were included. Sixty-three pairs of CSF and blood samplings were obtained. All pairs were divided into the 4 groups in accordance with presence/absence of NI-CNS or systemic infection. In cases without both NI-CNS and systemic infection (group 4) CSF PSP was 406±203.1 pg/ml. In cases without NI-CNS and with systemic infection (group 2) CSF PSP was 614.9±315 pg/ml. In cases with NI-CNS and without systemic infection (group 3) CSF PSP was 547.8±264.3 pg/ml. In cases with both NI-CNS and systemic infection (group 1) CSF PSP was 731.1±389.7 pg/ml. The ROC analysis showed that in neurocritical patients without systemic infection CSF PSP 537 pg/ml meant NI-CNS with sensitivity 68.8% and specifcity 85.7%.CONCLUSION The normal value of the CSF PSP is 50-100 pg/ml. CSF PSP more than 537 pg/ml in neurocritical patients without systemic infection meant NI-CNS with 688% sensitivity and 857% specifcity. CSF PSP may be used for diagnosing NI-CNS in neurocritical patients as an additional marker only. CSF may be used as an additional diagnostic criterion, but further research is needed. |
