Cidofovir use in acyclovir-resistant herpes infection.

TL;DRAbstract

Herpes infections continue to be prevalent, especially in immunocompromised patients. Some of these patients will develop resistant HSV infections. Therefore, it is important to explore new treatment options. Animal studies have shown cidofovir to be effective in the treatment and prevention of HSV infections. Human data are limited, with only one randomized, double-blind, placebo-controlled trial performed to date. The results from this study look promising; however, due to the small sample size, a larger clinical trial is warranted. The human data available as case reports are suboptimal in the quality of reporting time frames for resolution of lesions/symptoms and outcomes of therapy. Another problem with the case report data is that the TK status of the herpes simplex isolates was not reported. This would have helped substantiate the acyclovir resistance seen in these patients. It was evident in these case reports that acyclovir resistance can be overcome, as acyclovir-resistant st
