[Migratory erythema (Lyme borreliosis). Clinicoepidemiologic features of 50 patients].

BACKGROUND AND OBJECTIVE: Erythema migrans (EM) is the earliest and most common manifestation of the infection caused by B. burgdorferi (Lyme borreliosis). The objective of the present work was to report the clinicoepidemiological features in a series of patients. PATIENTS AND METHODS: Retrospective collection of clinicoepidemiological features of the first fifty patients diagnosed of EM at La Rioja Hospital (March 1989-September 1998). RESULTS: In our series, no differences were observed regarding sex or living in a rural or urban area. Mean age was 41 years (range 9 to 78). In 70% of patients the antecedent of a tick bite was obtained and the incubation period was 6.48 days (1 to 15 days). The mean size of the lesions was 14.3 cm (5 to 40) and in 16% of patients satellite cutaneous lesions were observed. The areas where EM appeared were lower limbs and the perineal region (60%), chest (24%), head and neck (10%) and upper limbs (6%). Forty-eight percent of patients reported extra-cutaneous manifestations. All cases occurred during the spring, summer and autumn months, with a peak in June. The most common referred antecedent was walking in forest areas. All patients responded to antibiotic therapy. CONCLUSIONS: EM is common in the studied environment and presents with a marked polymorphism.

[Seroepidemiology of Bartonella henselae infection in a risk group].

BACKGROUND: Bartonella henselae infections are closely related to a number of clinical conditions of growing interest in our environment. As cats are the reservoir, and their bites and scratches are the main transmission mechanism, we attempted to study the seroepidemiology of the infection caused by this microorganism in a risk group of patients (cat owners) and a control group (blood donors). PATIENTS AND METHODS: October 1977. Measurement of antibody titres to B. henselae at different dilutions (breakpoint > or = 1:64) by indirect immunofluorescence (IFI) in 83 cat owners and 85 blood donors. Also, an epidemiologic investigation was carried out (age, sex, alcohol, intake, common cat exposure, cat bite or cat scratch, number and age of cats, bite or presence of fleas, use of repellents, clinical picture consistent with cat scratch disease [CSD]). RESULTS: Twenty-four cat owners (28.9%) and five blood donors (5.9%) had titres > or = 1:64 (OR: 6.51; 95% CI: 2.32 to 22.9). Also, the logistic regression analysis showed an association with daily alcohol intake and the previous antecedent of lymph node enlargement of unknown origin among cat owners. CONCLUSIONS: A high prevalence of antibodies to B. henselae was demonstrate among cat owners.
