[Clinical and Laboratory Predictors for Forecasting the Outcomes of Ixodes Tick-Borne Borreliosis].

Objective: Our aim was to identify the most informative clinical and laboratory predictors of chronicity of Ixodes tick-borne borreliosis in the acute phase of the disease based on the "optimal cut-off values" (COV) and the predicted probability of the outcomes.

Methods: A retrospective cohort controlled study was carried out. We used the technique of ROC-analysis to estimate the information content of the clinical and laboratory indicators in patients with Ixodes tick-borne borreliosis in the acute phase of the disease with erythemal (n =16), non-erythemal (n = 77) forms of Ixodes tick-borne borreliosis and co-infection with the tick-borne encephalitis (n = 68) for the prediction of the outcomes: recovery or chronization.
