The aim of this study was to evaluate the usefulness of IgM anti-Tick-Borne Encephalitis (anti-TBE) intrathecal synthesis in the diagnosis and prediction of the clinical course of the disease. Thirty-six patients were included in the study (patients reported symptoms such as fever, headache, fatigue, and nausea/vomiting). CRP, White Blood Cells (WBC), pleocytosis, Cerebrospinal Fluid (CSF) protein concentration, CSF albumin concentration, serum IgM, serum IgG, CSF IgM, CSF IgG, IgM Index, IgG Index, and IgG Index/IgM Index ratio were the parameters which were examined in the individuals. An analysis of correlation presented statistical significance between IgM Index and pleocytosis and protein concentration in CSF in the whole group of individuals. IgM Index and IgG Index/IgM Index ratio may be used in the prediction of severity of TBE. The most probable link between the IgM intrathecal production and severity of TBE may be a result of delayed seroconversion to IgG, and therefore not an adequate response to the virus presence.

Background: Adrenomedullin (ADM) is a multifunctional peptide with vasoregulatory, antimicrobial, and anti-inflammatory properties. Its stable fragment, mid-regional pro-adrenomedullin (MR-proADM), is a validated biomarker in sepsis and systemic infections, but its role in viral neuroinfections remains unexplored. Tick-borne encephalitis (TBE), caused by the tick-borne encephalitis virus (TBEV), is a major viral infection of the central nervous system (CNS) associated with long-term neurological sequelae. This study aimed to assess MR-proADM levels in cerebrospinal fluid (CSF) and serum of patients with TBE and to evaluate their diagnostic utility and pathophysiological significance. Methods: This retrospective observational study included 20 patients with confirmed TBE and 14 non-infectious neurological controls. MR-proADM concentrations were measured in paired CSF and serum samples using an ELISA assay. Statistical analyses included group comparisons (Mann–Whitney U test), correlation analyses (Spearman’s r), and receiver operating characteristic (ROC) curve evaluation. Results: Serum MR-proADM levels at baseline (SER1) were significantly lower in TBE patients compared with controls (p = 0.0197). The CSF/serum MR-proADM ratio differed significantly between groups (p = 0.0063) and showed the best diagnostic performance (AUC = 0.816, 95% CI 0.63–0.93; sensitivity 79%, specificity 80%). MR-proADM concentrations in CSF correlated with total CSF protein (r = 0.53), suggesting an association with blood–CSF barrier dysfunction. Strong reproducibility was observed for serum MR-proADM between sampling points (r = 0.83). Conclusions: MR-proADM levels in CSF and serum are altered in patients with TBE, indicating its potential as a biomarker of CNS infection and inflammation. The CSF/serum MR-proADM ratio may serve as a sensitive indicator of blood–CSF barrier involvement, while decreased serum levels may reflect impaired systemic neuroprotective response. These findings highlight a possible role of ADM in neuroimmune regulation during viral encephalitis and warrant validation in larger prospective studies.
