Abstract
Objectives

Assess clinical and serological data as parameters indicative of a possible evolution to endocarditis after an episode of acute Q fever.

Patients and methods

Retrospective cohort study of evolution to endocarditis after an acute Q fever episode, analyzing the clinical and serological evolution and the antibiotic treatment administered.

Results

Eighty patients were recruited, 20% of whom had phase I IgG antibody levels1:1024 in the first 3 months. Only 44% of the patients underwent antibiotherapy in the acute phase; only 2 patients underwent extended antibiotherapy. Fifteen percent of the patients underwent an echocardiogram. None of the patients had symptoms suggestive of chronic infection or progressed to endocarditis after a median follow-up of 100 months, regardless of the early increase in phase I IgG antibodies.

Conclusions

The early increase in phase I IgG antibodies in asymptomatic patients is not associated with progression to endocarditis despite not undergoing prolonged antibiotic treatment.

Resumen
Objetivo

Valorar los datos clínicos y serológicos como parámetros indicativos de posible evolución a endocarditis tras un episodio de fiebre Q aguda.

Pacientes y métodos

Estudio de cohortes retrospectivo de la evolución a endocarditis tras un episodio de fiebre Q aguda, analizando evolución clínica, serológica y tratamiento antibiótico recibido.

Resultados

Se reclutó a 80 pacientes, presentando el 20% niveles de anticuerpos IgG de fase i ≥ 1:1.024 en los primeros 3 meses. Solo el 44% recibió antibioterapia en la fase aguda; únicamente 2 enfermos recibieron antibioterapia prolongada. Se realizó ecocardiograma al 15%. Ningún paciente presentó síntomas indicativos de infección crónica ni evolucionó a endocarditis tras una mediana de seguimiento de 100 meses, independientemente de la elevación precoz de anticuerpos IgG de fase i.

Conclusiones

La elevación precoz de anticuerpos IgG fase i no se asoció a evolución a endocarditis a pesar de no haberse realizado tratamiento antibiótico prolongado en pacientes asintomáticos.
