INTRODUCTION:

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.

METHODS:

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.

RESULTS:

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).

CONCLUSIONS:

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.
