RESUMO
An incidence of sepsis, septic shock, systemic inflammatory response syndrome (SIRS) and multiple organ dysfunction syndrome (MODS) is still actual clinical problem. Inducing factors and clinical pictures are similar to recently reported data from comparable populations in North America, Europe and Australia. The most important complication of severe sepsis is organ dysfunction observed in over 30% of sepsis patients hospitalized in intensive care unit. Applied intensive therapy including new generations of antibiotics gives an increase in clinical recovery. However, a hospital mortality of sepsis patients is over 30%.

THE AIM: of the study was to evaluate the seroprevalance of antibodies against Anaplasma phagocytophilum and Babesia Microti in healthy north-eastern Poland, adult population. MATERIAL AND METHODS: The study was conducted in a group of 142 healthy adults (mean age 19-22), bitten by ticks within last 2 years. The control group consisted of 50 adults from central Poland (nonendemic area). The antibody levels for A. phagocytophilum (IgG/Ap-Ab) and B. microti (IgM/Bm-Ab) were evaluated in two series of samples from the same persons (interval 5-6 months) by immunoenzymatic tests (Borrelia Biomedica, Austria), immunofluorescence test (Human Granulotic Ehrlichiosis IFA IgG and Babesia microti IFA IgG from MRL Diagnostics). RESULTS: Positive results for A. phagocytophilum were defined as titres > or =1:256 and for B. microti > or =1:64 and B. burgdorferi > or = 11 BBU/ml. Positive results for IgG B. burgdorferi during the first collection were revealed in 16% (n=24/142) of individuals from endemic area and in 4% (n=2/50) of the control group, which was statistically relevant (p<0,05). IgG A. phagocytophilum antibodies were present in 3,5% (n=5/142) of individuals from the endemic area, but for IgG B. microti antibodies (IgG/Bm-Ab) no positive results were found. No IgG antibodies against A. phagocytophilum and B.microti, were found in individuals from non-endemic area. During the second collection, in individuals from the endemic area, the antibodies against B. burgdorferi were found in 9,8% (n=14/142), IgG A. phagocytophilum antibodies (IgG/Ap-Ab) in 4,9% (n=7/142) and against B. microti (IgG/ Bm-Ab) in 1,4% (n=2/142). The antibodies against B. Burgdorferi were found in 2% (n=1/150) of the control group during the second collection, and no IgG against A. phagocytophilum and B. microti were found. CONCLUSION: [corrected] Evaluating the seroprevalance of the studied antibodies in both collections, a conclusion was drawn that there was no significant increase of antibodies levels directly after the highest exposition to tick bites. None of individuals showed 4-fold antibody level increase between the first and second collection. The seroconversion for IgG/Bm-Ab antibodies was present in 1,4% (n=2/142) of individuals, in those 2 cases a 2-fold antibodies level increase was observed. As far as IgG/Ap-Ab antibodies are concerned the seroconversion was observed in 2,1% (n-3/142), but only one case shown a 3-fold antibodies level increase. No seroconversion of B. burgdorferi antibodies were found in the second collection.
