Sažetak
Neuroborreliosis includes a variety of neurological disorders caused by Borrelia burgdorferi sensu lato. Clinical manifestation of neuroborreliosis is not pathognomonic. The etiological diagnosis is based mainly on serological tests and determination of specific anti-B. burgdorferi antibodies in cerebrospinal fluid (CSF). Specific antibodies response is influenced by phenotypic differences among B. burgdorferi species, different antigenic structure, their different geographic spreading, and patient's possibility to react to infection. In some patients with neuroborreliosis antibodies could be produced only intrathecally. Therefore, it is always necessary to test serum and CSF simultaneously and determine the CSF/serum antibody index. In our study serological results of 28 patients with clinical diagnosis of neuroborreliosis were analyzed. Serum and CSF anti-B.burgdorferi IgM and IgG antibodies were determined by recombinant indirect ELISA (rELISA; Biomedica, Wien, Austria) and capture ELISA for intrathecal antibody synthesis detection by CSF/serum antibody index determination (cELISA; IDEIA Lyme Neuroborreliosis, Dako, Denmark). All sera positive results were confirmed by Western blot (WB; Mikrogen, (67,9 %) patients had confirmed rELISA results by WB. All serological results should be interpreted according to clinical and epidemiological data and used to confirm the clinical diagnosis, while serologic assays for anti-B. burgdorferi antibodies have not been standardized yet.
