[Effects of nonoxinol 9 on RFLP typing of postcoital vaginal smears].

Abstract

Nonoxinol 9 effectively inactivates high titres of HIV in vitro, which suggest its use for reducing HIV-transmission via sexual intercourse. Therefore, the suggestion has been made for the treatment of sexual assault victims with a topical anti-HIV agent such as nonoxinol 9 as soon as possible after a sexual assault has occurred. From the forensic point of view it becomes pertinent to determine whether or not nonoxinol 9 would have an adverse effect on the high-molecular weight deoxyribonucleic acid (DNA) in vaginal swabs and thereby impact RFLP results. The study demonstrates that nonoxinol 9 does not have a negative effect on the ability to produce RFLP patterns. Therefore, the early administration of the topical anti-HIV agent nonoxinol 9 has to be considered as an important step in the medical treatment of sexual assault victims.
