RESUMEN

Objetivo:

Determinar la utilidad clínica de los marcadores biológicos de fase aguda de infección bacteriana (procalcitonina, proteína C reactiva [PCR] y recuento leucocitario) en la enfermedad invasiva meningocócica durante un brote epidémico. Pacientes y

métodos:

Se estudiaron 36 enfermos con síndrome febril que acudieron al servicio de urgencias de nuestro hospital durante un período de 6 meses. En todos los pacientes se realizaron determinaciones de niveles séricos de procalcitonina, PCR, recuento leucocitario y hemocultivo.

Resultados:

La enfermedad invasiva meningocócica, confirmada por hemocultivo, apareció en 7 de los 36 enfermos estudiados. La presentación clínica más habitual fue un síndrome febril de menos de 24 h que evolucionó a sepsis en horas posteriores. La comparación de las concentraciones de procalcitonina y PCR en los pacientes con y sin enfermedad meningocócica reveló que para valores de procalcitonina y PCR > 10 y > 49,95 ng/ml, respectivamente, tenían una elevada sensibilidad, especificidad y valores predictivos, aunque valores de procalcitonina inferiores a0,5 ng/ml tenían valor clínico al descartar la enfermedad fácilmente. En el caso del recuento de leucocitos no se pudo determinar un valor adecuado que tuviera significación clínica, aunque los pacientes con infección meningocócica presentaban recuentos más altos.

Conclusiones:

El hallazgo de niveles de procalcitonina inferiores a0,5 y/o 49,95 ng/ml de PCR en niños y jóvenes con fiebre de menos de 24 h de evolución indica una baja probabilidad de enfermedad invasiva meningocócica en situaciones epidémicas (AU)
ABSTRACT

Objective:

To determine the clinical utility of biological markers of the acute phase of bacterial infection (procalcitonin, C-reactive protein and leukocyte count) in invasive meningococcal disease during an epidemic cluster. Patients and

methods:

Thirty-six patients with feverish syndrome who visited the emergency unit of our hospital within a 6-month period were studied. In all patients, serum procalcitonin and Creactive protein levels and leukocyte count were determined, and blood culture was performed.

Results:

Invasive meningococcal disease, confirmed by blood culture, was found in seven of the 36 patients studied. The most frequent clinical presentation was a feverish syndrome of less than 24 hours of onset, progressing to sepsis in subsequent hours. Comparison of procalcitonin and Creactive protein concentrations in patients with and without meningococcal disease revealed that procalcitonin and C reactive protein levels greater than 10 ng/ml and49.95 ng/ml respectively had high sensitivity, specificity and predictive values. Procalcitonin levels < 0.5 ng/ml were useful to easily rule out invasive meningococcal disease. In the case of leukocyte count, no value with clinical significance could be established, although counts were higher in patients with invasive meningococcal disease.

Conclusions:

The finding of prolactin levels of < 0.5 ng/ml and/orC-reactive protein levels of < 49.95 ng/ml in children or teenagers with fever of less than 24 hours of onset indicates a low probability of invasive meningococcal disease in epidemic situations (AU)
