PRADO, Damián et al. Perfil de parámetros hematológicos en el HIV pediátrico y los cambios asociados al tratamiento antirretroviral. Acta bioquím. clín. latinoam. [online]. 2023, vol.57, n.3, pp.273-280. ISSN 0325-2957.

Hematologic abnormalities are common during human immunodeficiency virus (HIV) infection. Our aim was to describe hematological and immunological profiles present in antiretroviral treatment (ART)-naïve infected children and the changes observed after 36 months of ART initiation. Medical records of exposed children attended at this hospital in the 2008-2018 period were reviewed. Children between 6 months and 14 years were included. An automated blood analyser ADVIA 2120, a FACScalibur BD flow cytometer, and a Nuclisens EasyQ bioMérieux real-time PCR were used to determine different parameters. In 486 medical records evaluated, 58 patients ART-naïve were found, 30 due to recent diagnosis and 28 for incorrect adherence or abandoned treatment. In both groups, a percentage decrease in hemoglobin (Hb) (53% and 43%), mean corpuscular volume (MCV) (43% and 7%) and LTCD4+ (37% and 57%) levels respectively, was observed, without significant alterations in other hematological parameters. Twenty-two children with ART correct adherence increased significantly CD4+T cells (t0:18.8±9%, t1:32.7±6%), Hb (t0:10.9±1.6 g/dL, t1:12.6±1.1 g/dL) and MCV (t0:78.7±4.5 fL, t1:101.9±5.6 fL) levels, with simultaneous decrease of viral load (VL), (t0:4.4±0.75 log, t1:<1.70 log), after 36 months of follow-up. The reduction in Hb levels observed in 50% approximately of patients without ART would be associated with viral action and time of evolution of the infection. The increase in Hb levels and an associated macrocytosis would be related to the CD4+ T cells increase and VL decrease.
