Role of cidofovir in the treatment of DNA virus infections, other than CMV infections, in immunocompromised patients.
Cidofovir is a nucleotide analog marketed for the treatment of human cytomegalovirus infections in immunocompromised patients. An increasing number of reports have appeared on the use of cidofovir for the treatment of other severe DNA virus infections in immunocompromised patients. The activity of cidofovir against herpes simplex viruses resistant to classic (acyclovir and/or foscavir) therapy has been widely documented. Cidofovir has also been used for the treatment of other herpesvirus infections, such as drug-resistant varicella-zoster virus, and Epstein-Barr virus-induced proliferative diseases. For papillomavirus infections, cidofovir represents a valuable alternative to the conventional therapies, which are mostly based on surgery, as in the treatment of laryngeal papillomatosis. The role of cidofovir in the treatment of polyomavirus infections is more controversial, but here too, cidofovir represents, to date, the only available efficacious therapeutic modality. Cidofovir has demonstrated activity against all poxviruses and represents a unique therapeutic modality for use against these viruses, particularly in the immunosuppressed host, should this prove necessary (eg, in a bioterrorism scenario).
