Efectividad y seguridad de inhibidores de integrasa en la gestante con infección VIH en la Cohorte de embarazadas de la Comunidad de Madrid / Effectiveness and safety of integrase inhibitors in HIV-infected pregnant women followed up in the Madrid Cohort

INTRODUCCIÓN: El riesgo de transmisión vertical (TV) del VIH depende fundamentalmente de la edad gestacional de inicio del tratamiento antirretroviral y la carga viral materna al parto. Son crecientes las pautas con inhibidores de integrasa (INI) en embarazadas con situaciones de riesgo. Nuestro objetivo fue revisar la experiencia con INI en la Cohorte de Madrid de madres-niños. PACIENTES Y MÉTODOS: Estudio retrospectivo, multicéntrico, observacional, de gestantes con infección por VIH-1 expuestas a INI de 9 hospitales públicos durante 2000-2017. RESULTADOS: Hubo 67 gestantes (cohorte: 1.423) y 68 neonatos (el 17,6% prematuros, el 34,3% con profilaxis combinada). No hubo casos de TV. Veinte mujeres se diagnosticaron en la gestación actual. De 43 con tratamiento antirretroviral previo a gestación, el 65% recibía INI preconcepcional. El más empleado fue raltegravir (80,5%). Aumentó significativamente (p = 0,02) la proporción de madres con carga viral indetectable al parto. La tolerancia a INI fue adecuada. Hubo anomalías congénitas menores en el 11,7% de los niños. CONCLUSIONES: Los INI parecen seguros y eficaces como prevención de TV. Nuestros hallazgos refuerzan su utilidad como intensificación en gestantes que llegan al tercer trimestre con pauta no supresora

INTRODUCTION: The risk of HIV-1 mother-to-child transmission (MTCT) is associated mainly with gestational age at which antiretroviral therapy begins and the HIV-1 RNA plasma viral load at delivery. Regimens with integrase inhibitors (INI) are increasing in high-risk pregnant women. The objective was to review the experience with INI in a Madrid Cohort of mother-infant pairs. PATIENTS AND METHODS: Retrospective, multicentric, observational study, of HIV-infected pregnant women exposed to INI. Patients of 9 hospitals were included (2000-2017). RESULTS: Sixty-seven pregnant women exposed to INI (cohort: 1,423) and 68 children (17.6% premature babies, 34.3% with combined postexposure prophylaxis). There were no cases of MTCT. Of 24 women with no previous antiretroviral therapy, 20 were diagnosed in current pregnancy. Of 43 women with antiretroviral therapy before pregnancy, 65% received INI before conception. Raltegravir was the most used (80.5%). There was a statistically significant increase (p = 0,02) of mothers with undetectable viral load at delivery. INI were well tolerated. In 11.7% of exposed children minor congenital anomalies were detected. CONCLUSIONS: INI seem safe and effective in the prevention of MTCT. Our findings support their use as intensification regimens in pregnant women with high risk of MTCT

Jóvenes y VIH. Conocimiento y conductas de riesgo de un grupo residente en España / Young adults and HIV. Awareness and risk behaviour of a group living in Spain

Introducción: El contacto sexual es actualmente en España la primera vía de contagio de VIH. Pese a los descensos en el número de nuevas infecciones en mujeres y consumo de drogas, en hombres se mantiene estable. El presente estudio pretende evaluar conductas de riesgo y conocimientos sobre VIH en una muestra de jóvenes en España. Métodos: Se realizó un estudio observacional descriptivo transversal utilizando un cuestionario sobre salud sexual y conocimiento sobre el VIH adaptado del Instituto Nacional de Estadística. El grupo estuvo compuesto por jóvenes no infectados por VIH. Se incluyó la variable riesgo sexual (alto y bajo), siendo de riesgo alto los sujetos que habían tenido tres o más parejas y no utilizaban preservativo en todas las relaciones. Resultados: Se encuestaron 243 jóvenes (65,6% mujeres) de entre 16 y 36 años (media = 25,7; DE = 4,1) (16-24 años: 134 sujetos; 25-29 años, 60 sujetos; más de 30 años, 47 sujetos). El 40,9% contestaron que utilizaban el preservativo en todas sus relaciones y el 61% que no perciben ningún riesgo de infección. De forma mayoritaria no se encuentran diferencias significativas en conocimiento sobre vías de transmisión entre los grupos de alto y de bajo riesgo. Los métodos de protección que se asociaron significativamente con las diferencias en riesgo sexual fueron lavarse tras las relaciones sexuales, tener pocas parejas, uso de espermicidas y carga viral indetectable (p < 0,05). Conclusiones: El principal resultado del estudio es la infravaloración personal de riesgo indicado según las diferencias encontradas entre la valoración personal y el índice de riesgo sexual. Se encuentran resultados tanto positivos como negativos en cuanto al conocimiento sobre el VIH

Introduction: Sexual intercourse is currently the main route of HIV infection in Spain. Despite decreases in new infections among women and drug users, the rate remains stable in men. The aim of this study was to assess risk behaviour and HIV awareness in a sample of young adults in Spain. Methods: A cross-sectional, observational, descriptive study was performed on a non-HIV infected sample, using a questionnaire on sexual health and HIV awareness adapted from the Spanish National Institute of Statistics. A sexual risk variable was included (high and low), which was classified as high if subjects had had three or more sexual partners and did not always use a condom in all their sexual encounters. Results: 243 subjects were included (65.6% women) aged between 16 and 36 years (mean = 25.7; SD = 4.1) (16-24 years: 134 subjects; 25-29 years: 60 subjects; over 30 years: 47 subjects). Approximately 40.9% said that they used a condom in all sexual relations and 61% did not perceive any risk of infection. There were no significant differences in awareness of infection routes between the high and low risk profiles. Washing after sex, having few partners, spermicide use and having undetectable viral load were protective measures significantly associated with differences in sexual risk (P < .05). Conclusions: The main finding of the study was the underestimation of risk of infection, analysed after differences found between self-assessment and sexual risk. Both positive and negative results were found concerning HIV awareness

Once-daily antiretroviral therapy in a cohort of HIV-infected children and adolescents.

We evaluated the evolution over time of once-daily antiretroviral therapy in HIV-infected children and its relationship with adherence. An increase on the prevalence of once-daily antiretroviral therapy was observed over time (from 0.9% in 2002 to 44.2% in 2011). There was no difference in adherence regarding once-daily or BID regimens in 2011. Adherence was related to age and pill burden.
