<body><![CDATA[<p align="justify"><font face="verdana" size="2">Con respecto a la prevalencia de infecci&oacute;n por VHC en pacientes con LP, los resultados de este estudio contrastan en forma importante con estudios de Estados Unidos,<sup>12,</sup><sup>18,</sup><sup>20 </sup>Espa&ntilde;a,<sup>15,</sup><sup>22</sup> Jap&oacute;n,<sup>10,</sup><sup>11</sup> Alemania,<sup>16</sup> Italia,<sup>14</sup><sup>,17</sup> Turqu&iacute;a,<sup>19 </sup>Brasil,<sup>21</sup> Paquist&aacute;n<sup>23</sup> y M&eacute;xico.<sup>24</sup> Estos estudios encontraron prevalencias desde 6.84% en Turqu&iacute;a<sup>19</sup> a 62% en Jap&oacute;n.<sup>10</sup> Hay un estudio proveniente de Nigeria<sup>30</sup> que encontr&oacute; prevalencia de infecci&oacute;n por VHC en pacientes con LP menor a la encontrada entre pacientes con otras dermatosis no asociadas con VHC, pero m&aacute;s alta que entre los controles aparentemente normales. Sin embargo, similar a nuestros hallazgos, hay estudios que no encontraron asociaci&oacute;n entre infecci&oacute;n por VHC y LP, provenientes de Francia,<sup>25</sup>,<sup>26</sup> Reino Unido<sup>27</sup>,<sup>28</sup> y Holanda,<sup>29 </sup>con prevalencias desde 0% hasta 4.9%.</font></p>     <p align="justify"><font face="verdana" size="2">En nuestro pa&iacute;s, Franco y Jurado<sup>24</sup> reportaron un estudio en el cual 21 (51.2%) de 41 pacientes con LP tuvieron reacci&oacute;n de polimerasa en cadena (PCR) positiva para VHC. Estos resultados difieren de lo observado en el nuestro, aunque estos autores usaron otro m&eacute;todo diagn&oacute;stico. La prueba de inmunoensayo de tercera generaci&oacute;n utilizada por nosotros tiene en inmunocompetentes una sensibilidad y especificidad mayores de 99%,<sup>5</sup> lo que sugiere que es comparable a la prueba de PCR.</font></p>     <p align="justify"><font face="verdana" size="2">Es de llamar la atenci&oacute;n la heterogeneidad de los resultados a nivel internacional, Cribier et al<sup>25</sup> han se&ntilde;alado que esta variaci&oacute;n quiza se deba a diferentes niveles de endemicidad de infecci&oacute;n por VHC de acuerdo al &aacute;rea geogr&aacute;fica; y prevalencias de VHC han sido reportadas con un margen desde 0.15% en Escandinavia a 38% en el norte de Egipto,<sup>5</sup> lo que parece apoyar esa idea.</font></p>     <p align="justify"><font face="verdana" size="2">En conclusi&oacute;n, encontramos prevalencia de serolog&iacute;a positiva para VHC en pacientes con LP menor a la reportada en la literatura. En el an&aacute;lisis estad&iacute;stico no encontramos asociaci&oacute;n, aunque nuestra muestra es peque&ntilde;a. En vista de que en todos los estudios se han encontrado pacientes con LP sin infecci&oacute;n por VHC, sugerimos que deben considerarse otros factores en la patog&eacute;nesis de esta dermatosis.</font></p>     <p align="justify"><font face="verdana" size="2">&nbsp;</font></p>     <p align="justify"><font face="verdana" size="2"><b>Referencias</b></font></p>     <!-- ref --><p align="justify"><font face="verdana" size="2">1.<b> Arndt KA. </b>Lichen planus.
