Mitochondrial assessment in asymptomatic HIV-infected paediatric patients on HAART.

Background: HAART can cause mitochondrial DNA (mtDNA) depletion, which may lead to mitochondrial dysfunction. We aimed to determine whether mtDNA and mitochondrial function abnormalities are present in peripheral blood mononuclear cells from asymptomatic HIV-infected children.

Methods: A cross-sectional study in peripheral blood mononuclear cells was performed in 47 asymptomatic (free from any HIV- or AIDS-related active condition or HAART-related toxicity), HIV-infected, HAART-treated children and adolescents and 27 uninfected healthy paediatric patients.

Mitochondrial impact of human immunodeficiency virus and antiretrovirals on infected pediatric patients with or without lipodystrophy.

We determined the mitochondrial status of a group of HIV-infected children, some with body fat abnormalities (BFA). We included 24 controls, 16 HIV-infected untreated, 26 HIV-infected treated, 6 BFA-untreated, and 21 BFA-treated patients. Genetic, translational, and functional mitochondrial values were measured.

Evolution of mitochondrial DNA content after planned interruption of HAART in HIV-infected pediatric patients.

HAART-related long-term toxicities, many of them ascribed to mitochondrial (mt) toxicity of the nucleoside analogues, are being increasingly reported in HIV-infected children. HIV infection can also cause mt damage. Case series include 13 vertically HIV-infected pediatric patients (9 girls, median age 10.
