INTRODUCTION: Chlamydia trachomatis and Neisseria gonorrhoeae are responsible for 3-10% of sexually transmitted diseases in adolescents. 75% are asymptomatic. International standards recommend annual screening for C. trachomatis in sexually active women under 26 years. Self-collected vaginal swab is one of the less invasive screening methods, it is well accepted by patients and rarely used in our country.
AIM: To determine the frequency of C. trachomatis and n. gonorrhoeae by a self-sampling method of vaginal swab and its acceptability in a group of adolescents and young adults.
PATIENTS AND METHODS: Women 18 to 25 years old. Vaginal samples were processed by nucleic acid amplification tests, Gen Probe APTIMA Combo2. Data were collected on sexual behavior and perception of self-sampling by survey.
RESULTS: We studied 344 patients with an average age of 21.7 years. Detection of C. trachomatis was positive in 7.9% women and it was not found in any of the patients studied for N. gonorrhoeae. 98% considered self-sampling instructions easy to understand, 87.5% felt comfortable taking the sample.
CONCLUSIONS: Prevalence of C. trachomatis in the study population was similar to that described in other national and international studies. N. gonorrhoeae was not found in this series, which is consistent with literature reports. The self-sampling technique of vaginal sample was well accepted by the patients. However, they were anxious about the quality of the sample. According to our results, it is important to emphasize the importance of annual detection of these pathogens and that self-sampling technique is a valid alternative.
