 AB    To assess the potential therapeutic effects of zidovudine, rhesus
       macaques were inoculated with simian immunodeficiency virus (SIV) strain
       SMM/B670 at birth and infused either continuously or intermittently with
       zidovudine for 6-7 months. Zidovudine did not prevent infection but did
       significantly increase survival time, which was associated with lower
       serum p26 viral core antigen levels, a lower virus burden in the
       cerebrospinal fluid (CSF), and lower CSF quinolinic acid levels than in
       untreated monkeys. Two of 5 infected, untreated monkeys developed motor
       impairment within 6 months following infection, whereas motor
       impairments did not occur in infected, zidovudine-treated monkeys until
       after the drug was discontinued. Zidovudine treatment was well tolerated
       by rhesus infants with minimal, transient side effects. These results
       demonstrate that zidovudine treatment significantly decreases virus load
       within the central nervous system (CNS) and delays the onset of CNS
       dysfunction and immune disease in rhesus monkeys perinatally infected
       with SIV.
