    Background: HIV-infected children surviving until adulthood have been transitioning to adult outpatient health care service in Brazil since the late 2000's. Deterioration of clinical condition is expected during this period, as reported among youths with non-communicable chronic diseases. Despite their young age, they are long-term hosts of the virus, have prolonged exposure to antiretroviral therapy and have suffered from the social determinants and stigma of HIV infection since early childhood. Objectives: This study aimed to (1) describe demographic and clinical characteristics at the first appointment at adult care service following pediatric care of a cohort of Brazilian youths living with HIV since childhood; and (2) retrospectively address adherence and clinical variables in the last two years of pediatric follow-up. Methods: Descriptive study. Results: 41 consecutive patients referred to adult outpatient care from a pediatric HIV unit were enrolled, median age 19 years, and median lifetime CD4+ nadir 117 cell/mm(3); 89% reported previous AIDS-defining conditions. At first laboratory assessment in adult care, only 46% had undetectable (<400 copies/ml) HIV viral load and the median CD4+ count was 250 cell/mm(3). Conclusion: Youths living with HIV at the transition from pediatric to adult care had poor treatment adherence, low lifetime CD4+ cell nadir, low CD4 cell count and detectable HIV viral load. Health care providers should closely monitor these adolescents in a youth friendly environment, prepared for open communication about all aspects of their health.

    High rate of virologic suppression with darunavir/ritonavir plus optimized background therapy among highly antiretroviral-experienced HIV-infected patients: results of a prospective cohort study in Sao Paulo, Brazil
    (2013) VIDAL, Jose Ernesto; SONG, Alice Tung Wan; MATOS, Maria Laura; BARTMANN, Daniel; ANJOS, Guilherme dos; MIRANDA, Erique Jose Peixoto de; FREITAS, Angela Carvalho; DALBEN, Mirian de Freitas; SANTANA, Claudinei; SEGURADO, Aluisio Cotrim; BARRETO, Claudia Cortese; HERNANDEZ, Adrian Vladimir
    Objectives: To assess the virologic and immunological response of darunavir/ritonavir plus optimized background therapy in highly antiretroviral-experienced HIV-infected patients in Brazil. Methods: Prospective cohort study carried out in a tertiary center in Sao Paulo, Brazil. Three-class antiretroviral-experienced patients with confirmed virologic failure began darunavir/ritonavir plus optimized background therapy (nucleoside/tide reverse transcriptase inhibitors +/- raltegravir +/- enfuvirtide +/- maraviroc) after performing a genotypic resistance assay. Clinical evaluation and laboratory tests were collected at baseline and at weeks 12, 24, and 48. Multivariate analysis was performed to identify predictors of virologic response at 48 weeks. Results: Ninety-two patients were included. The median of darunavir resistant mutation was 1 (range 0-6). The median genotypic sensitivity score in the optimized background therapy was 2 (interquartile range 1-2). At week 48, 83% (95% CI: 75-90%) had an HIV RNA level <50 copies/mL and the median CD4 cell count was 301 (interquartile range 224-445) cells/mm(3). Baseline HIV RNA >100 000 copies/mL was inversely associated with virologic success at week 48 (HR: 0.22, 95% CI: 0.06-0.85, p=0.028). Conclusions: Darunavir/ritonavir plus optimized background therapy was a highly effective salvage regimen under clinical routine conditions in a referral center in Brazil, which is similar to the reported in high-income countries.
