Human granulocytic ehrlichiosis (HGE) is a recently described rickettsiosis in the United States transmitted by Ixodes species ticks. In Europe, only a few studies on HGE exist. Two hundred Bulgarian patients with tick bites and 70 healthy blood donors were tested for HGE using an immunofluorescence assay with the HGE agent as an antigen. Elevated antibody titers (> or = 1:80) were found in 14 (9.7 %) of 145 patients with erythema migrans, two (8%) of 25 tick-exposed patients with lymphadenopathy only, one (20%) of five patients with tick bite with fever, chills, and headache, one (4%) of 25 healthy tick-exposed patients, and two (2.9%) of 70 blood donors. These results show for the first time that HGE is probably common in southeastern Europe. The study provides evidence of coinfection or concurrent infection of patients with Lyme disease and HGE, thus supporting the possible role of I. ricinus for transmitting the HGE agent.

To compare clinical features and assess risk factors for human granulocytic ehrlichiosis (HGE) and early Lyme disease, we enrolled patients in a case-control study during the 1996 and 1997 tick seasons. Clinical and demographic characteristics were assessed for patients with laboratory-confirmed cases of HGE or Lyme disease, and risk factors were compared with those of matched control subjects. We identified 83 persons with Lyme disease, 27 with HGE, and 11 with apparent coinfection. Unsuspected Ehrlichia infection was identified in 8 (13%) of 60 patients with Lyme disease. Patients with HGE were older and more likely to have fever, chills, or dyspnea than were those with Lyme disease only. Most patients with apparent coinfection did not have hematologic abnormalities. In the risk factor analysis, tickborne illness was independently associated with rural residence and camping. The clinical spectrum of HGE overlaps that of Lyme disease, and physicians in areas of endemicity should consider both diseases in treating patients with a compatible rash or febrile illness.

We conducted a case-control study in Wisconsin to determine whether some patients have long-term adverse health outcomes after antibiotic treatment for human granulocytic ehrlichiosis (HGE). A standardized health status questionnaire was administered to patients and controls matched by age group and sex. Consenting patients provided blood samples for serologic testing. Among the 85 previously treated patients, the median interval since onset of illness was 24 months. Compared with 102 controls, patients were more likely to report recurrent or continuous fevers, chills, fatigue, and sweats. Patients had lower health status scores than controls for bodily pain and health relative to 1 year earlier, but there was no significant difference in physical functioning, role limitations, general health, or vitality measures. The HGE antibody titer remained elevated in one patient; two had elevated aspartate aminotransferase levels. HGE may cause a postinfectious syndrome characterized by constitutional symptoms without functional disability or serologic evidence of persistent infection.

In order to assess the validity of definitions for human granulocytic ehrlichiosis (HGE), epidemiological, clinical and laboratory findings for 13 patients with confirmed HGE and 21 patients fulfilling criteria for probable HGE were compared. The patients were identified during a prospective study on the aetiology of febrile illness occurring after a tick bite, performed in Slovenia from 1995 to 2002. Significant differences between the 2 groups were found for age of patients, duration of fever before the first examination, and several clinical and laboratory parameters including the occurrence of chills, myalgia, arthralgia, leukopenia, thrombocytopenia, abnormal liver function tests results, and elevated concentration of C-reactive protein. All the abnormalities were established more often in patients with confirmed HGE than in those with probable HGE. Patients with confirmed HGE exhibited higher geometric mean titre values and higher peak antibody titres to Anaplasma phagocytophilum that developed later in the course of their illness. The differences indicate that in some patients fulfilling criteria for probable HGE the signs and symptoms most probably are not the result of a recent infection with A. phagocytophilum.
