[Epidemiological and clinical aspects of chronic neuroborreliosis with parkinsonism in the Yaroslavl region].
OBJECTIVE
To study clinical and epidemiological features of chronic neuroborreliosis (CB) with parkinsonism (PS) in the Yaroslavl region.


MATERIALS AND METHODS
The study included the main group of patients (n=5) with CB and PS of the average age of 61±3/4, the comparison group (n=6) with Parkinson's disease (PD) of the average age of 54.7±8.3 and a group of 6 healthy people. Diagnostic criteria of Lyme disease based on the recommendation of the US Centers for Disease Control and Prevention and criteria for the diagnosis of PS were used. PD was diagnosed by the criteria of the Parkinson's UK Brain Bank. Serological diagnosis of CB was carried out using immunoenzyme assay and immunoblotting in dynamics. The following scales were administered: HOEHN and YAHR, MMSE, MFI-20, CGI. All patients underwent MRI of the brain and spinal cord.


RESULTS AND CONCLUSION
PS in patients with CB in the Yaroslavl region was observed in 2.17% of cases among patients with CB and amounted to 0.25% of all cases of the revealed PS. The features that complicate the diagnosis of PS within chronic borreliosis were: the absence of erythema migrans in the history of 80% of patients and in more than half of the cases of the acute period of the disease, the presence in most patients (60%) of asymmetric onset of the PS with rest tremor in 40% cases and a significant reduction in the severity of PS as a result of therapy with levodopa. The onset of complete regression of the clinical manifestations of PS and reduction of the titer of antibodies and obtaining the negative results during dynamic serological study in response to prolonged antibiotic therapy provided a basis to verify the diagnosis of borreliosis with PS in these patients.
