Antiviral agents for ocular adenovirus infections.
Despite significant knowledge of the molecular biology and genetics of adenovirus, no specific antiviral agent has been developed for use in adenovirus infections. This contrasts with the situation in herpes simplex virus (HSV) and human immunodeficiency virus (HIV) infections, in which antiviral agents target specific enzymes. Antiviral agents active against HSV and interferons have been used in the treatment of ocular adenovirus infections with limited effect. Some newer nucleoside analogues have inhibitory activity against adenovirus in vitro and their effect is being assessed in newly developed animal models. Live vaccines have been used in both the United States and Canada to protect military recruits against adenovirus-induced respiratory disease. However, the inoculating strains are not normally associated with epidemic keratoconjunctivitis (EKC). There is a low prevalence of antibody against strains of adenovirus inducing EKC. Until such time as specific antiviral agents against adenovirus are developed, the mainstays of therapy will remain topical antibiotics to eliminate any secondary bacterial infection and topical steroids to suppress the immune response against adenovirus or adenovirus-infected cells. Neither form of treatment is adenovirus specific.
