[Ehrlichiosis--a disease rarely recognized in Poland].
Ehrlichioses constitute a group of acute zoonoses caused by the infection with the microorganisms belonging to the genera Ehrlichia, Anaplasma and Neorickettsia (Rickettsiaceae). Presence of human granulocytic ehrlichiosis (HGE) caused by infection with Anaplasma phagocytophila (A. phagocytophila) and transmitted by Ixodes ricinus tick has been confirmed in Poland. All the cases described so far were noted in the area of endemic prevalence of Lyme borreliosis (north-east of Poland). Lack of characteristic symptoms makes the diagnosis of HGE difficult. It should be suspected in patients exposed to tick bites during the preceding few weeks, in whom acute, febrile illness accompanied by leucopenia and thrombocytopenia develops. The course of infection may be serious, or even life-threatening, in patients more than 40 years old; consequences of co-infection with A. phagocytophila and other tick-borne pathogens remain not well known. There is probably no risk of the development of chronic HGE. As specific diagnostic methods are not widely accessible in Poland, empirical therapy with doxycycline may be of benefit in suspected HGE cases.
