ABSTRACT

Background: Sexually transmitted infections (STIs) affect sexual and reproductive health of millions of men. Pathogens such as human papillomavirus (HPV), herpes simplex virus type 1 and 2 (HSV-1 y HSV-2), Chlamydia trachomatis,Mycoplasmagenitalium,Mycoplasma hominis and Ureaplasma urealyticum are associated with STIs. Aim: To detect pathogens associated with STIs in symptomatic men and its relationship with sexual behavior. Methodology: DNA was obtained from exfoliated cells of penis from 20 symptomatic men. Pathogens were detected using qPCR or PCR followed by reverse line blot. Sexual behavior was evaluated through a survey. Results: Two or more infectious agents were detected in 50% of samples. U. urealyticum was found in 25%, meanwhile C. trachomatis and M. hominis were detected in 15%. VHS-1, VHS-2 andM. genitalium were detected only in 5%. HPV was found in all samples. The most frequent HPV genotypes were VPH 16, 11, 70. There were no statistical link found between sexual behavior and the studied microorganisms Conclusion: Infectious agents associated with STIs were detected in symptomatic men. HPV was the most frequent pathogen and it was detected in multiple genotypes. It is necessary to increase the sample size to associate significantly the sexual behavior with the results.


Introducción: Las infecciones de transmisión sexual (ITS) afectan la salud sexual y reproductiva de millones de hombres. Patógenos como virus papiloma humano (VPH), virus herpes simplex (VHS-1 y VHS-2), Chlamydia trachomatis, Mycoplasma genitalium, Mycoplasma hominis y Ureaplasma urealyticum están asociados a ITS. Objetivo: Detectar patógenos asociados a ITS en hombres sintomáticos y relacionarlos con su conducta sexual. Metodología: Se obtuvo ADN de exfoliado celular del pene de 20 hombres sintomáticos de ITS. Los patógenos fueron detectados por RPC cuantitativa o RPC seguida de reverse line blot. La conducta sexual se evaluó mediante una encuesta. Resultados: En 50% de las muestras se detectaron dos o más agentes infecciosos; U. urealyticum fue detectado en 25% de los casos, mientras que C. trachomatis y M. hominis en 15%. VHS-1, VHS-2 y M. genitalium sólo en 5%. VPH se encontró en todas las muestras y los genotipos más frecuentes fueron VPH 16, 11, 70. No se encontró relación estadística entre los microorganismos estudiados y la conducta sexual de los encuestados. Conclusión: Se detectaron agentes infecciosos asociados a ITS en hombres sintomáticos, siendo VPH el más frecuente y encontrándose en múltiples genotipos. Es necesario aumentar el tamaño de muestra para asociar significativamente la conducta sexual a los resultados.
