Prevalencia de la infección por Chlamydia trachomatis y factores de riesgo de infecciones transmisibles sexualmente en estudiantes universitarios

Abstract

Chlamydia trachomatis genital infection is nowadays considered one of the most frequent causes of sexually transmitted infections (STI) in the world, mainly affecting the group of young people under 25 years old. The aim of this study was to determine the prevalence of C. trachomatis infection in newly admitted students to Universidad Nacional del Sur, Bahía Blanca, Argentina, and to evaluate the risk factors to acquire STI. For that purpose, 204 young college students with a mean age of 19 were involved in this study. Each participant delivered a sample of first-void urine and completed a questionnaire which was then submitted anonymously. The research for C. trachomatis was done on 114 valid samples through a technique of DNA amplification, whose molecular target was the gene ompA. Four cases of infection by C. trachomatis were detected with a prevalence of 3.5%. The risks factors associated to the infection were a history of 7 or more partners since the start of sexual activity and contact with a new sexual partner in the last 4 months. The prevalence of such infection reflects a moderate circulation of this microorganism in the studied population. This fact, along with some aspects shown by the questionnaire results, would characterize a population having a low risk profile for acquiring STIs. However, some other information obtained from the questionnaires gave some opposite evidence, which would alert us on the need of keeping watch, raising awareness and implementing preventive actions in this population.

FACTORES RELACIONADOS A INFECCIÓN POR CHLAMYDIA TRACHOMATIS, HOSPITAL SANTA MARIA DEL SOCORRO-ICA, 2011 a 2016

“…No mantener una relación estable, con cambios frecuentes de parejas, las predispone a una mayor frecuencia de infección; en nuestro estudio encontramos que el 66,95 % de las mujeres con Chlamydiasis no tienen una pareja sexual estable; sin embargo, difiere de los resultados encontrados por Tamayo A. et al donde el porcentaje de presentación es mayor, 87,10 % (7). Con respecto a la edad de inicio de las relaciones sexuales, se encontró que el 44,92 % tuvieron como inicio de relaciones sexuales a los 16 años o menos, siendo un inicio precoz y aunque se observó una mayor tendencia del 52,90 % en el estudio realizado por Occhionero M. et al (8). Así mismo se observa que el 79,66 % de las pacientes con infección por chlamydia trachomatis presentaron 4 a más parejas sexuales.…”

“…Los resultados de nuestro estudio muestran que el 92,10 % de las pacientes con infección por chlamydia trachomatis manifestaron que practicaban sexo vaginal. Occhionero M. et al encontró datos coincidentes, 96,10 % de las mujeres con Chlamidyasis practicaban sexo vaginal (8). Los condones de látex, cuando se usan de manera habitual y correcta, pueden reducir el riesgo de transmisión de esta bacteria.…”

“…Estos datos coinciden con estudios realizados en jóvenes de Medellín y de Sabana de Cundinamarca (11)(12)(13)(14).…”

Decrease in Sperm Quality due to Infection of Human Papilloma Virus and Chlamydia trachomatis

“…For example, in a study carried out in Argentina (2015), 204 participants with an average age of 19 were screened for Chlamydia trachomatis. It was found that the prevalence was of 3.5% [31].…”

“…In most cases it is asymptomatic leading to an untreated infection. It is reported that in approximately 50% of men and in 75% of women the primary infection does not show any symptoms [31]. However, it is estimated that the ratio of infected people with Chlamydia who develop symptoms vary depending on the study and the methodology.…”
