Background: Information regarding epidemiology and clinical presentation of HIV-infection and AIDS in the immigrant population in Spain is scant.
Methods: Prospective multicenter study, based on the electronic database of the Spanish VACH Cohort, a project participated by 23 hospitals throughout
the country. We assess sociodemographic and HIV-infection-related data in the patients of the Cohort, and compare results of the immigrant with those of the autochthonous populations with nonparametric tests.
Results: We include 14,499 patients, 84.1 % are Spaniards and 15.9 % natives from other countries: 165 (1.1 % of the total) from Nigeria, 163 (1.1 %) from Ecuador, 160 (1.1 %) from Colombia, 138 (1.0 %) from Argentina, 134 (0.9 %) from Portugal, and 131 (0.9 %) from Brazil.
Table 1 shows results that refer to the first two visits, except for AIDS and follow-up data that refer to the whole study period. Values are medians when not otherwise specified.

Tuberculosis was the most common AIDS-defining condition both in the immigrant and the autochthonous population, and Pneumocystis pneumonia was the second in both populations.
Conclusions: Sociodemographic features and risk factors for HIV-infection are different in the immigrant and the autochthonous populations of Spain, while most characteristics of HIV disease are similar in both groups.
