AB Evidence has accumulated suggesting that HIV-infected patients are under
chronic oxidative stress. Perturbations to the antioxidant defense
system, including changes in levels of ascorbic acid, tocopherols,
carotenoids, selenium, superoxide dismutase, and glutathione, have been
observed in various tissues of these patients. Elevated serum levels of
hydroperoxides and malondialdehyde also have been noted and are
indicative of oxidative stress during HIV infection. Indications of
oxidative stress are observed in asymptomatic HIV-infected patients
early in the course of the disease. Oxidative stress may contribute to
several aspects of HIV disease pathogenesis, including viral
replication, inflammatory response, decreased immune cell proliferation,
loss of immune function, apoptosis, chronic weight loss, and increased
sensitivity to drug toxicities. Glutathione may play a role in these
processes, and thus, agents that replete glutathione may offer a
promising treatment for HIV-infected patients. Clinical studies are
underway to evaluate the efficacy of the glutathione-repleting agents,
L-2-oxothiazolidine-4-carboxylic acid (OTC) and N-acetylcysteine (NAC),
in HIV-infected patients.
