RESUMEN
AIM: To assess levels of several cytokines in blood of patients with tick-borne borreliosis (Lyme disease) with different clinical variants of the disease. MATERIALS AND METHODS: Study of complex of proinflammatory cytokines (IFNalpha, IL-1beta, IFNgamma, IL-2, IL-4, IL-8) during course of the disease was performed by solid-phase ELISA using domestic diagnostic kits (Scientific Manufacturing Organization "Proteinovyi Contur", "Cytokine" Ltd., Saint Petersburg). Levels of TNFalpha was determined by ELISA using commercial kits "Boehringer Manheim" (Austria). RESULTS: Performed comparative clinico-laboratory analysis demonstrated increased levels of LL-2, IL-4, and IL-8 in patients during acute phase of tick-borne borreliosis that could point to host's response on bacterial infection. It should be noted that in patients with arthritis levels of LL-4 and IL-2 remained high during recovery phase that probably determined by possible persistence of Borrelia burgdorferi. CONCLUSION: Further research of cytokines during Lyme borreliosis could have important diagnostic and prognostic value.
