ABSTRACT
Trichomonas vaginalis, a causative agent of trichomoniasis, may trigger symptomatic or asymptomatic nongonococcal urethritis and chronic prostatitis in men. Despite the availability of highly sensitive diagnostic tests, such as nucleic acid amplification tests, including PCR, few prospective studies present data on male T. vaginalis infection in South Korea. In the present study, the prevalence of T. vaginalis and associated clinical conditions were evaluated in 201 male patients from a primary care urology clinic in South Korea. The prevalence of T. vaginalis infection in our cohort was 4% (8/201) by PCR. T. vaginalis infection was common in men older than 40 years (median age, 52 years). Among the 8 Trichomonas-positive patients, 87.5% (7/8) had prostatic diseases, such as prostatitis and benign prostatic hyperplasia, and 25.0% (2/8) and 12.5% (1/8) were coinfected with Chlamydia trachomatis and Mycoplasma genitalium, respectively. Our results suggest that T. vaginalis infection is not rare in men attending primary care urology clinics in South Korea, especially in those older than 40 years, in whom it may explain the presence of prostatic disease. The possibility of T. vaginalis infection should be routinely considered in older male patients with prostatic diseases in South Korea.

Se realizó un estudio retrospectivo en 6 409 casos consecutivos en un lapso de enero de 1992 a febrero de 1997, se seleccionaron 183 frotis nasales y 271 faríngeos provenientes de 396 pacientes. Chlamydia trachomatis fue el agente etiológico en el 67.80 por ciento de los frotis nasales y 8.11 por ciento de las muestras faríngeas. La infección nasal es casi siempre secundaria a la infección ocular y a su vez es un factor de diseminación y de falta de respuesta adecuada al tratamiento, por lo que es indispensable identificar el problema y dar tratamiento simultáneo

La evidencia de exposición previa a Chlamydia pneumoniae fue evaluada en 353 sujetos sanos de Santiago de Chile. Se efectuó determinación sérica de anticuerpos (IgG) específicos anti-Chlamydia pneumoniae con antígenos de la cepa AR-39 proporcionados por la Washington Research Foundation, con técnica de inmunofluorescencia indirecta. Títulos iguales o mayores de 1:16 fueron considerados positivos. 134 sueros fueron positivos para Chlamydia penumoniae, con título máximo de 1:256. Concluimos que en esta muestra la seroprevalencia fue de 38 por ciento y que en un título igual o mayor de 1:512 sugiere el diagnóstico de infección aguda por Chlamydia pneumoniae
