title: Study of patients diagnosed with advanced HIV in the HAART era--OMEGA Cohort.
abstract: Our objective is to analyse patients diagnosed with late-stage HIV infection in the highly active antiretroviral therapy (HAART) area. A prospective, observational study of all patients with an initial CD4 < 50 x 10(6)/L was carried out. Epidemiological, clinical and HAART-associated data were analysed. Survival rates were estimated and pairs of survival curves were compared. The statistical program used was SPSS (version 10). In all, 349 HIV-infected patients were diagnosed, 117 (33.5%) had late-stage disease, mean CD4 23.9 x 10(6)/L and mean viral load (VL) 5.38 log10. In 98 men, mean age 39.5 years, percentage of AIDS cases at their first attendance was 83.8%. The median follow-up period was 28 months and 27 died. Pneumocystis carinii was the most frequent cause of AIDS (24.4%) and death (18.5%). Survival rates at 12, 24 and 36 months were 95.6%, 85.8% and 72.4%. HAART was started in 82.1%. VLs < 50 copies/mL at one, two and three years of treatment were 55.2%, 55.7% and 58.0%. Resource utilization included 0.58 hospitalization/patient/year and 0.07 events/patient/year. HAART-related complications were as follows: 50% lipodystrophy, 9.7% hypertension, 22.2% hyperglycaemia, 26.4% hypercholesterolaemia, 31.9% hypertrygliceridaemia and 18.1% mixed hyperlipaemia. Over one-third of our patients have advanced HIV infection at diagnosis. However, the outcome is favourable, with a good immunovirological response and few new opportunistic events. HAART-related complications were frequent.
