- W2507633178 abstract "La transmisión vertical (TV) es relevante en la epidemiología global del virus de la inmunodeficiencia humana (VIH), representando la principal vía de infección en la edad pediátrica. Los objetivos del estudio fueron determinar la tasa de TV del VIH y su tendencia epidemiológica entre la población autóctona e inmigrante en Catalunya entre 2000-2014. Estudio observacional prospectivo de parejas madre-hijo expuestas al VIH atendidas en 12 hospitales de Catalunya en 2000-2014. Se estimó la tasa de TV del VIH aplicando un modelo bayesiano de regresión logística. Se utilizó el software estadístico R y WinBUGS. Se analizaron 909 gestantes, 1.009 embarazos y 1.032 niños; datos de origen materno en el 79,4% de las mujeres, el 32,7% inmigrantes y de estas el 53,0% de África subsahariana. La tasa de TV del VIH fue del 1,4% (14/1.023; IC95% 0,8-2,3). El riesgo de TV del VIH fue 10 veces menor en mujeres con buen control virológico (p = 0,01), al que llegaron 2 tercios de ellas. No hubo diferencias en la tasa de TV del VIH entre mujeres autóctonas e inmigrantes (p = 0,6). La proporción de mujeres inmigrantes fue significativamente mayor en el período 2008-2014 (p < 0,0001), en relación con el diagnóstico de la infección por VIH (p < 0,0001) y la administración de antirretrovirales (p = 0,02) durante el embarazo, y con la viremia indetectable próxima al parto (p < 0,001). Existe un aumento progresivo de gestantes inmigrantes con VIH en Catalunya. Aun siendo la mayoría diagnosticadas durante el embarazo, la tasa de TV del VIH no fue diferente a la hallada en las mujeres autóctonas. Mother-to-child transmission (MTCT) is relevant in the global epidemiology of human-immunodeficiency virus (HIV), as it represents the main route of infection in children. The study objectives were to determine the rate of HIV-MTCT and its epidemiological trend between the Spanish-born and immigrant population in Catalonia in the period 2000-2014. A prospective observational study of mother-child pairs exposed to HIV, treated in 12 hospitals in Catalonia in the period 2000-2014. HIV-MTCT rate was estimated using a Bayesian logistic regression model. R and WinBUGS statistical software were used. The analysis included 909 pregnant women, 1,009 pregnancies, and 1,032 children. Data on maternal origin was obtained in 79.4% of women, of whom 32.7% were immigrants, with 53.0% of these from sub-Saharan Africa. The overall HIV-MTCT rate was 1.4% (14/1,023; 95% CI; 0.8-2.3). The risk of MTCT-HIV was 10-fold lower in women with good virological control (P = .01), which was achieved by two-thirds of them. The proportion of immigrants was significantly higher in the period 2008-2014 (P < .0001), for the HIV-diagnosis (P < .0001), and antiretroviral administration (P=.02) during pregnancy, and for undetectable viral load next to delivery (P < .001). There were no differences in the rate of MTCT-HIV among Spanish-born and immigrant women (P = .6). There is a gradual increase in HIV pregnant immigrants in Catalonia. Although most immigrant women were diagnosed during pregnancy, the rate of MTCT-HIV was no different from the Spanish-born women." @default.
