ABSTRACT

Con el objetivo de correlacionar las pruebas VDRL (Venereal Disease Research Laboratory) y USR (unheated serum reagin) para diagnóstico de neurosífilis, se evaluaron los resultados en 106 líquidos cefalorraquídeos. De 106 líquidos cefalorraquídeos procesados con VDRL y USR, 7,54% fue reactivo por los dos métodos, 90,57% no reactivo por ambos métodos y 1,89% discordante. VDRL y USR clasifican de la misma manera, p no significativa (prueba de Mac Nemar). Si bien la VDRL en líquido cefalorraquídeo es la prueba serológica estándar para neurosífilis, la USR podría ser usada para su diagnóstico, ya que no existe diferencia estadísticamente significativa con la VDRL, es más económica, más práctica y más accesible en el mercado.


The results of 106 cerebrospinal fluids have been evaluated with the aim of correlating the VDRL (Venereal Disease Research Laboratory) and USR (unheated serum reagin) tests for neurosyphilis diagnosis. From 106 cerebrospinal fluids processed with VDRL and USR, 7.54% was reactive by the two methods, 90.57% was nonreactive by both methods and 1.89% was discordant. Mac Nemars test determined that VDRL and USR classified in the same way (not significative p). Although the VDRL in cerebrospinal fluids is the standard serologic test for neurosyphilis, the USR could be used as well for its diagnosis, since it is not significatively different from the statistical point of view with the VDRL; it is less expensive, more practical and more easily available in the market.
