Use of new technologies to notify possible contagion of sexually-transmitted infections among men / Uso de las nuevas tecnologías para la notificación del posible contagio de infecciones de transmisión sexual entre hombres

Background: Among men who have sex with men (MSM), the association between searching for sexual partners’ on the Internet and increased risk of sexually transmitted infections (STIs)/HIV infection, together with current low levels of partner notification (PN), justifies a study to explore the intention to use new communication technologies for PN in Spain. Methods: Two cross-sectional surveys were performed: the first was administered online to visitors to web pages where the survey was advertised; the second was administered on paper to patients attending an STI Unit and centres similar to Community-Based Voluntary Counselling and Testing centres. Results: The study population comprised 1578 Spanish residents (median age, 34 years [range: 18 to 74]); 84% lived in urban areas, and 69% reported searching for sexual partners on the Internet. Thirty-seven per cent would be willing to use a website for PN, 26% did not know if they would use one, and 37% would not want to use one. The main reasons for not intending to notify STI/HIV were 'shame or fear' (stable partner) and 'not knowing how to contact them' (casual partner). The preferred method of notification was face to face (73%) for both stable and casual partners, although using new technologies (Short Messaging System, e-mail, web page, phone applications) was widely accepted for notifying casual partners. Conclusions: Fighting stigma and promoting alternative methods of PN among MSM and health professionals through new technologies could increase the frequency of PN. This approach will improve early detection and reduce transmission in Spain (AU)

Antecedentes: Entre los hombres que tienen sexo con hombres, la asociación entre buscar parejas por internet y el incremento de riesgo para presentar una Infección de Transmisión Sexual (ITS), junto con la baja frecuencia de la práctica de la notificación a las parejas sexuales expuestas a un infectado justifican explorar la intención de uso de las nuevas tecnologías para facilitar dicha notificación en España. Métodos: Se han utilizado dos estudios transversales: el primero, administrado 'online' a los visitantes de páginas web donde se publicitaba la encuesta; el segundo, administrado en formato papel en una Unidad Especializada de Atención a las ITS y otros centros similares a los de soporte y realización de pruebas. Resultados: Participaron 1578 personas residentes en España, mediana de edad 34 años (Rango: 18- 74); 84% de áreas urbanas, 69% buscaron parejas sexuales en internet. Un treinta y siete por ciento utilizarían un página web si estuviera disponible, un 26% no sabían si lo harían y otro 37% no la utilizarían. Las razones principales para no tener la intención de notificar de ITS/VIH a una pareja estable fueron: 'miedo o vergüenza'; a una pareja ocasional: 'no saber cómo contactarla'. El método preferido para notificar fue el 'cara a cara o por teléfono' (73%), tanto en caso de pareja estable como ocasional. El uso de nuevas tecnologías (SMS, e-mail, web page, aplicaciones de teléfono) fue más aceptado en caso de pareja ocasional. Conclusiones: La lucha contra el estigma y la promoción del uso de nuevas tecnologías para la notificación a las parejas sexuales, entre los hombres que tienen sexo con hombres (HSH) y por parte de los profesionales de la salud, pueden aumentar la notificación, con los beneficios esperados de una más temprana detección de casos y una reducción de la transmisión en España (AU)

Neisseria gonorrhoeae: resistencias antimicrobianas y estudio de la dinámica poblacional. Situación en 2011 en Barcelona / Neisseria gonorrhoeae: Antimicrobial resistance and study of population dynamics. Situation in Barcelona in 2011

INTRODUCCIÓN: Las altas tasas de resistencia de Neisseria gonorrhoeae (NG) a ciertos antibióticos, junto con la aparición de cepas con sensibilidad disminuida y resistencia a las cefalosporinas, hacen de la infección gonocócica un problema de salud pública. Los objetivos del estudio fueron: realizar el seguimiento de la sensibilidad antimicrobiana de NG obtenidas entre enero y agosto de 2011, y estudiar su dinámica poblacional. MÉTODOS: Se estudió la sensibilidad mediante el método disco-difusión y E-test. El genotipado se realizó mediante el NG-MAST. RESULTADOS: De un total de 100 cepas, el 59% presentaron sensibilidad intermedia a penicilina y el 9% resistencia. Según EUCAST, se detectaron 3 gonococos con sensibilidad disminuida a ceftriaxona, 10 a cefixima y uno con resistencia de alto nivel a ambos (CMI 1,5 μg/ml). La CMI50 y la CMI90 a cefixima fue de 0,016 y de 0,125 μg/ml, mientras que a ceftriaxona fue < 0,016 y 0,064 μg/ml. El 99% presentó resistencia a doxiciclina, el 53% a ciprofloxacino, el 3% a azitromicina y el 1% a espectinomicina. El ST más prevalente fue el ST1407, mayoritariamente asociado a resistencia o sensibilidad disminuida a cefalosporinas o macrólidos. CONCLUSIÓN: NG ha desarrollado tasas importantes de resistencia a distintos antibióticos. Se ha detectado una cepa con resistencia de alto nivel a las cefalosporinas de tercera generación y varias con sensibilidad disminuida, además de observarse un aumento de la CMI50 y de la CMI90 a estos antibióticos. La estructura poblacional de NG permanece estable y común al resto de Europa, aunque se han identificado 2 nuevos secuencio tipos (ST7226 y ST7227) con potencial para seleccionarse y adquirir altos niveles de resistencia a cefalosporinas

BACKGROUND: Due to the high rates of antimicrobial resistance to certain antibiotics, together with the emergence of Neisseria gonorrhoeae (NG) with reduced susceptibility and resistance to third-generation cephalosporins, gonococcal infection is becoming a public health problem. The objectives of the study were: To keep track of the antimicrobial susceptibility of NG strains obtained from January to August 2011. To study the population dynamics. METHODS: The antimicrobial susceptibility was studied by disk-diffusion and E-test. The genotyping was performed by NG-MAST method. RESULTS: Of a total of 100strains studied, 59% showed intermediate sensitivity to penicillin and 9% were resistant. According to EUCAST, we detected 3gonococci with reduced susceptibility to ceftriaxone, 10 to cefixime and one with high-level resistance to both antibiotics (MIC 1.5 μg/ml). MIC50 and MIC90 to cefixime were 0.016 and 0.125 μg/ml, respectively, whereas to ceftriaxone they were < 0.016 and 0.064 μg/ml, respectively. Almost all (99%) of the strains were resistant to doxycycline, 53% to ciprofloxacin, 3% to azithromycin, and 1% to spectinomycin. The most prevalent ST was ST1407, predominantly associated to resistance or reduced sensitivity to cephalosporins or macrolides. CONCLUSIONS: NG has developed significant rates of resistance to various antibiotics. One strain has been detected with high level resistance to third generation cephalosporins, and several strains with reduced susceptibility. An increase in MIC50 and MIC90 to these antibiotics has also been observed. NG population structure remains stable and common to the rest of Europe, although two new ST (ST7226 and ST7227) have been identified that could be selected and acquire high levels of resistance to cephalosporins
