RESUMO
Objective To study the characteristics of HIV infection in the gypsy (Roma) population in Spain, as compared with those of the Caucasian, non-gypsy majority. Design Cross-sectional, historical cohort study from the Spanish VACH Cohort. Methods Patients attending VACH clinics between 1 June 2004 and 30 November 2004 were classified according to their racial and ethnic origin as gypsies, Caucasian non-gypsy Spanish natives (CNGN), and other (the last being excluded from this study). Their sociodemographic and clinico-epidemiological characteristics were compared, as well as the KaplanMeier curves of time to AIDS, or death, or disease progression (either of the 2 outcomes).Results4819 (48%) of 10,032 cases included in the VACH database were eligible: 210 (4.2%) were gypsies and 4252 (84.8%) were CNGN. Differences were observed in age, household, academic, inmate, marital, and employment history. Injecting drug use had been the most frequent mechanism of transmission in both groups, but to a greater extent among gypsies (72% versus 50%; P<0.000). Sex distribution, CD4 cell counts, and viral loads at the first visit were similar in the 2 groups, as was the percentage of patients with previous AIDS, percentage receiving antiretrovirals, and percentage subsequently starting antiretroviral therapy. Up to 1 April 2005, 416 new AIDS cases and 85 deaths were recorded. The percentage of these outcomes did not differ between groups, but log-rank test showed a shorter time to AIDS and disease progression among gypsies. Conclusions The sociodemographic characteristics of gypsies, the largest minority in the VACH Cohort, show differences relative to those of CNGN. HIV-related outcomes suggest that gypsies have a poorer prognosis (AU)
Objetivo estudiar las características de la infección por el VIH en gitanos en España, en comparación con las de la mayoría caucásica no gitana (CNG).Métodos estudio transversal y de cohortes históricas en la Cohorte VACH. Clasificamos a los pacientes que acudieron a las clínicas participantes en VACH entre el 1 de junio de 2004 y el 30 de noviembre de 2004 de acuerdo a su raza y etnia, como «gitanos», «nativos españoles CNG» u «otros» (estos, excluidos de este estudio). Comparamos sus características sociodemográficas y clinicoepidemiológicas, así como sus curvas de KaplanMeier del tiempo hasta sida, muerte o progresión de la enfermedad (cualquiera de ambos).Resultados4819 (48%) de 10.032 casos recogidos en la base de datos de VACH fueron incluidos en el estudio: 210 (4,2%) eran gitanos y 4.252 (84,8%) eran nativos CNG. Observamos diferencias en sus distribuciones por edad, domicilio, estudios, antecedentes penales, situación laboral y marital. La inyección de drogas había sido el mecanismo de transmisión del VIH más frecuente en los dos grupos, pero más marcadamente en los gitanos (72% frente a 50%; p<0,000). La distribución por sexos, los recuentos de linfocitos CD4 y las cargas virales en la primera visita fueron similares en ambos grupos, así como las proporciones de pacientes con sida previo y las de quienes estaban ya en, o iniciaron entonces, tratamiento antirretroviral. Hasta el 1 de abril de 2005 se registraron 416 nuevos casos de sida y 85 muertes. La proporción de ambos resultados fue similar en ambos grupos, pero la prueba del rango logarítmico demostró una evolución más rápida a sida y a progresión de la (..) (AU)
