ABSTRACT

Resumen La infección de transmisión sexual por Chlamydia trachomatis, tiene una alta prevalencia en Chile y otras latitudes, y se asocia a graves riesgos para la salud reproductiva de quienes se infectan. El cribado con autotoma de la muestra y detección mediante amplificación de ácidos nucleicos es la forma más eficaz de control sanitario. Hasta ahora, en Chile, el diagnóstico y manejo epidemiológico de C. trachomatis no se realiza en la salud pública. El Ministerio de Salud de Chile está haciendo importantes avances para iniciar esta implementación. La Sociedades Médicas se comprometen a participar en este proceso para lograr el eficaz control de esta infección en nuestra población.


The sexually transmitted infection caused by Chlamydia trachomatis has a high prevalence in Chile and other latitudes and is associated with serious risks to the reproductive health of those who become infected. Screening with self- collected samples and detection by amplification of nucleic acids is the most effective form of sanitary control. Until now, in Chile, the diagnosis and epidemiological management of C. trachomatis is not carried out in public health. The Ministry of Health of Chile is making important progress to start this implementation. The Medical Societies are committed to participate in this process to achieve effective control of this infection in our population.

ABSTRACT

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.


Chlamydia trachomatis y Neisseria gonorrhoeae son causantes de 3 a 10% de las infecciones de transmisión sexual en adolescentes. Las normas internacionales recomiendan su detección anual en mujeres sexualmente activas menores de 26 años. La adherencia a este tamizaje en mujeres jóvenes está limitada por el temor al examen ginecológico y alto costo del examen. Objetivo: Determinar la frecuencia de detección de C. trachomatis y N. gonorrhoeae por un método de auto-toma de muestra vaginal y su aceptabilidad en un grupo de adolescentes y jóvenes adultas. Pacientes y Método: Se incluyeron mujeres de 18 a 25 años atendidas en Clínica Las Condes y el Servicio de Salud Estudiantil de la Universidad de Chile, que fueron instruidas para autotoma de muestra vaginal. Luego de dar su consentimiento, las muestras fueron estudiadas mediante reacción de polimerasa en cadena para la detección de C. trachomatis y N. gonorrhoeae. Se recopilaron datos sobre conductas sexuales y percepción de la autotoma mediante encuesta. Se determinó la relación entre estos factores y la aceptabilidad del método. Resultados: Se reclutaron 344 mujeres, con una edad promedio de 21,7 años. La detección de C. trachomatis fue de 7,9% y no se encontró muestra positiva para N. gonorrhoeae. El reporte de flujo vaginal por la paciente se asoció a 1,5 veces mayor riesgo de C. trachomatis. El 98% consideró las instrucciones de la autotoma fáciles de entender, 87,5% se sintió cómoda al tomar la muestra. Conclusiones: La prevalencia de C. trachomatis en la población estudiada fue similar a lo descrito en otras series nacionales e internacionales; no se encontró N. gonorrhoeae en esta serie, lo que coincide con lo reportado en el extranjero. La técnica de autotoma de muestra vaginal fue bien aceptada por las pacientes; sin embargo, manifestaron ansiedad acerca de la seguridad de una toma adecuada. De acuerdo a nuestros resultados, es importante insistir en la detección anual de estos patógenos siendo la técnica de autotoma una alternativa válida.

ABSTRACT

Polycystic ovarian syndrome (PCOS), includes a wide spectrum of clinical symptoms and signs. Three different diagnostic classifications have been proposed to define this disease. The first one, published in 1990, known as the "NIH criteria" requires the simultaneous presence of hyperandrogenism and menstrual dysfunction in order to diagnose PCOS. Later on, in 2004, an expert panel met in Rotterdam and added to the previous criteria the presence ofpolycystic ovarian morphology (PCOM) detected by transvaginal ultrasonography The later classification broadened the spectrum of PCOS and also included women with oligomenorrhea and PCOM without hyperandrogenism or hyperandrogenism and PCOM without menstrual dysfunction. Finally, the Androgen Excess Society, published in 2006 new diagnostic criteria which required the presence of clinical or biochemical hyperandrogenism, with either PCOM or menstrual dysfunction to diagnose PCOS. We review the different classifications employed in the diagnosis of PCOS, the diverse phenotypes that may lead to the diagnosis of PCOS and their association with cardiovascular and metabolic complications.
