Introduction. Lyme neuroborreliosis (LNB) can manifest during the early and late stages of Lyme disease (LD). The aim of this study is to determine epidemiology and clinical findings in patients with LNB.
Methods. The research was conducted in Banja Luka at the University Clinical Center of Republic of Srpska (UCC RS) during a four-year period from 10/2017 to 10/2021. The research included 51 patients admitted to the hospital with some neurological symptoms that could lead to the LNB diagnosis. Patients had lumbar puncture with cytochemical analysis of cerebrospinal fluid (CSF), ELISA anti-Borrelia IgM/IgG in serum and CSF, Immunoblot anti-Borrelia IgM/IgG in serum, and other documentation about epidemiology and clinical findings in LNB.
Results. A statistically significant (p=0.017) higher proportion of female patients was observed. Most patients were between 50 and 60 years old. Most of them were retirees (31.37%), farmers, medical technicians followed with forestry workers, students etc. Most of examinees did not have information on previous tick bite (64.71%). The largest number (72.55%) did not have data on previous skin changes. The largest number of neurological symptoms at admission related to the feeling of tingling and weakness in the extremities, headache, dizziness and some ophthalmological symptoms. Patients also suffered from consciousness and speech disorder, anxiety, paresis n.VII. The largest number of examinees had some neurological symptoms up to three months prior the admission to the hospital.
Conclusion. Symptoms of LNB can be quite non-specific or possibly even mimic other neurological diseases. Involvement
of peripheral nervous system is dominant in adult patients. It is necessary to work on early diagnosis of LD and it is mandatory to report it to the national epidemiological service.
