Task: Intent Identification
Input (English): Selenium is an essential mineral for immunological function, performing crucial functions at the cellular level. This micronutrient has been determined to be frequently deficient in HIV infected patients, with correlations between reduced immunological function and greater susceptibility to opportunistic infections. Our aim was to evaluate the influence of time of exposure to antiretroviral therapy (ART) on the biochemical profile of selenium in HIV-infected patients.', 'We performed a cross-sectional study on 50 HIV-positive men with different quantitations of viral load and CD4+ T cells, who were either receiving or not receiving ART. Dual energy X-ray absorptiometry (DXA) to determine body composition, biochemical analysis of selenium and albumin, anthropometric measurements were performed. The subjects were divided into groups according to the use of ART or not: The Control Group (CG) was 10 treatment-naïve volunteers, Group G < 2 was 20 volunteers on ART for less than 2 years, and Group G > 2 was 20 volunteers on ART for >2 years.', 'The body mass index showed that all subjects were of normal weight. The group with a longer time of exposure to ART (G > 2) had undetectable viremia and a higher CD4+ T cell count: 593.1 ± 234.6 mm(3). Selenium values (μg/L) were 55.9 ± 11.9 for CG, 52.1 ± 10.5 for G < 2, and 66.9 ± 20.8 for G > 2, with a significant difference between groups G < 2 and G > 2 (p < 0.05), and only G > 2 showed normal selenium values.
