Niacin as a potential AIDS preventive factor.

A pentad of findings consistent with niacin depletion have been described in patients with AIDS. There are also clinical and laboratory data to support the potential benefit of niacin in HIV infection. In this paper, it is hypothesized that HIV infection induces niacin depletion, and that therapeutic niacin will act as an AIDS preventive factor. While viral inhibition is incontrovertibly the primary 'AIDS preventive factor', costly antiretroviral medications are simply out of reach for the majority of the world's HIV-infected people. Along with antiviral research, investigation must go forward to look at strategies to overcome the massive metabolic disruption caused by the production of approximately one billion virus particles per day. Niacin, the same B complex vitamin found in the early part of this century to be the 'pellagra preventive factor', is proposed here as a secondary 'AIDS preventive factor' in HIV-infected persons.
