The aim of the study was the evaluation of NF-κB concentration in serum and cerebrospinal fluid (CSF) of patients with diagnosis of tick-borne diseases: tick-borne encephalitis (TBE), neuroborreliosis (NB), anaplasmosis (ANA) and patients co-infected with tick-borne encephalitis virus and Anaplasma phagocythophilum (TBE + ANA). Additionally NF-κB concentration during acute and convalescent period was compared.


Sixty-seven patients with diagnosis of tick-borne diseases were included in the study. The control group (CG) consisted of 18 patients hospitalized because of headaches and had lumbar puncture performed. The NF-κB was measured by human inhibitory subunit of NF-κB ELISA Kit during acute and convalescent period.


In serum the significant differences were observed only in patients with TBE + ANA co-infection. In CSF the concentration of NF-κB was significantly higher in patients with TBE, TBE + ANA co-infection, and patients with NB than in CG. Receiver operating characteristic (ROC) curves analysis showed that NF-κB concentration in CSF differentiated patients with NB with CG; patients co-infected with TBE and ANA with CG and patients with TBE with CG. NF-κB concentration in serum differentiated patients co-infected with TBE and ANA with NB and with ANA, with TBE and with CG. In TBE group the serum NF-κB concentration significantly decreased in convalescent period, while in NB and TBE groups significant CSF decrease of NF-κB concentration was observed.
