Serum malondialdehyde in HIV seropositive children.
Human immunodeficiency virus (HIV) infection is associated with oxidative stress as it has been demonstrated in adult seropositive individuals. We show in this study that serum malondialdehyde (MDA) concentration of HIV infected children was significantly higher than in control children. Moreover, a statistically significant decreased serum antioxidant status was detected in HIV infected children when compared with controls. No correlation was found in HIV infected children between their clinical or immunological categories, CD4+ lymphocyte count or CD4+/CD8+ ratio, and MDA concentration or serum antioxidant status. Newborn from HIV seropositive mothers had also a higher MDA concentration in cord blood serum than their corresponding controls from HIV seronegative mothers, whereas no difference could be established in the serum antioxidant status between both groups. No apparent correlation could be established between birth weight, gestational age or APGAR test values, and MDA in any of these groups. The results presented, (i.e., the increase of MDA concentration in HIV seropositive infants and children, and the decrease in serum total antioxidants in HIV seropositive children) confirm the involvement of oxidative stress in the pathophysiology of this infection also in childhood. Because of the importance of oxidative stress and antioxidants for HIV viral replication, the adequacy of an adjuvant therapy with antioxidants should be considered; an adequate candidate for it could be N-acetyl-cysteine.
