PURPOSE: Tick-borne co-infections are a serious epidemiological and clinical problem. Only a few studies aimed to investigate the effect of tick-borne encephalitis (TBE) and human granulocytic anaplasmosis (HGA) co-infection in the course of the inflammatory process and the participation of chemokines in the pathomechanism of these diseases. The aim of the study was to evaluate CCL-4, CCL-17, CCL-20, and IL-8 serum concentrations in patients with HGA, TBE and HGA + TBE co-infection.
METHODS: Eighty-seven patients with HGA (n = 20), TBE (n = 49) and HGA + TBE (n = 18) were included to the study. The control group (CG) consisted of 20 healthy people. Concentrations of cytokines were measured in serum using commercial ELISA assays. In patients with TBE and HGA + TBE inflammatory markers were assessed during the acute and convalescent period. The results were analyzed using non-parametric tests with p < 0.05 considered as significant.
RESULTS: Before treatment, significantly higher concentrations of IL-8, CCL-4 and CCL-20 were observed in HGA patients. CCL-4 and CCL-20 concentrations were significantly higher in TBE patients compared to CG. Concentrations of IL-8, CCL-4, and CCL-20 were significantly higher in HGA + TBE than in CG. After treatment, a significant reduction of IL-8, CCL-4, and CCL-20 concentrations in TBE patients and IL-8 in HGA + TBE co-infection was observed. CCL-4 concentration was higher in HGA + TBE co-infection in comparison to patients with TBE after treatment.
CONCLUSIONS: Our study confirms that concentrations of IL-8, CCL-4, and CCL-20 are increased in the course of HGA and TBE. Their concentrations in serum may be used to monitor the course of TBE and HGA, as well as possibly detect co-infections with the diseases.
