[HIV and other sexually transmitted infections among migrant population in Spain: a scoping review].

BACKGROUND: Migration flows have the ability to disperse infectious agents and alter local epidemiologies. The aim of the study is to describe the socio-epidemiological, clinical and microbiology / molecular epidemiology of HIV / AIDS infection in the immigrant population.
METHODS: Review of the literature following the methodology Scoping review. A literature search in Medline and MEDES, original items made in Spain, published between 1998-2012, with people from Latin America, sub-Saharan Africa, North Africa, Asia and / or Eastern Europe was conducted.
RESULTS: 41 articles were selected. The most studied population was from Latin America (48.8%). Higher HIV prevalence than in native was observed in men who have sex with men from Latin America (18.1%), transvestite and transsexual sex workers from Latin America (23.3%), pregnant women (0.9%) and men and women from sub-Saharan Africa (9.1% and 7.5%). Risk behaviors were different depending on the country of origin and sex. The diagnostic delay of HIV infections reached 43%, with higher prevalence in immigrants from sub-Saharan Africa, which showed delayed diagnosis in 41% and resistance to anti-retroviral treatment in 13%. Immigrant women had more losses to follow up, worse immunological response to antiretroviral treatment and shorter time treatment failure.
CONCLUSION: Higher prevalence of HIV is presented by subjects from sub-Saharan Africa, men who have sex with men and transgender and transvestite sex workers from Latin America. Also pregnant women. Delayed diagnosis and resistance to treatment are more common in individuals from sub-Saharan Africa. Immigrant women presented poorer response to antiretroviral treatment.
