Background: Information regarding epidemiology
and clinical presentation of HIV-infection and AIDS in the immigrant population
in Spain is scant.
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.

|Gender male, %||68.7||76.7||< 0.001|
|HIV-risk factor, drug use, %||10.6||48.5||< 0.001|

|HIV RNA, copies per ml||26,915||26,303||0.491|
|AIDS cases, %||22.6||29.5||< 0.001|
|Follow-up, months||22.1||47.0||< 0.001|
was the most common AIDS-defining condition both in the immigrant and the autochthonous
population, and Pneumocystis pneumonia was the second in both populations.
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.
