[Determination of the concentration of platelet serotonin for the prediction of the two-wave course of tick-borne encephalitis].

The paper gives the results of an investigation of platelet serotonin levels in patients with tick-borne encephalitis to determine a criterion for predicting the development of its to-wave course. Fifty-five patients were examined at the height of tick-borne encephalitis (in the first 2-4 days): Group 1 included 39 patients with a one-wave course of the disease; Group 2 consisted of 16 patients with its two-wave course. Platelet serotonin concentrations were determined by enzyme immunoassay.

[Diagnostic value of determination of the blood concentrations of serotonin and high-sensitivity C-reactive protein in patients with tick-borne encephalitis].

The paper shows the informative value of changes in the serum levels of serotonin and high-sensitivity C-reactive protein in 44 patients in the acute period of tickborne encephalitis. Group 1 included 35 patients with non-paralytic neuroinfection; Group 2 comprised 9 patients with paralytic neuroinfection. The serum level of high-sensitivity C-reactive protein increased and that of serotonin decreased in relation to the form and severity of the disease at its height.

[Clinical manifestations in acute Lyme diseases].

Analyzing the clinical observations of 1343 patients, made in the Kama river region in 1991 to 2002, could establish a number of characteristic syndromes of the acute period of Ixodes tick-borne borreliotosis (ITBB). The early period of the diseases manifested itself as two forms: erythematous in 1041 (77.5%) patients and erythema-free in 302 (22.
