Cervicovaginal shedding of TT virus in HIV-infected women.

OBJECTIVE

TT virus (TTV) is frequently detected in the serum and in other body fluids of humans. Recently TTV-specific deoxyribonucleic acid has been detected in cervical specimens from apparently healthy women and in seminal fluid, suggesting that sexual transmission may be common.

STUDY DESIGN/METHODS: TT virus-deoxyribonucleic acid prevalence was assessed in paired samples of blood and cervical smears from 110 human immunodeficiency virus-positive women. Detection and typing of human papillomavirus (HPV) present in cervical smears was also performed.

RESULTS

The prevalence of TTV-deoxyribonucleic acid in cervical smears was 16.4%, without significant difference (p = 0.81) between HPV-positive (18.6%) and -negative (14.9%) samples. The distribution of high/middle and low-risk HPV types was similar in TTV-positive and -negative samples. On the contrary, women with multiple HPV infections had a significantly higher TTV-deoxyribonucleic acid prevalence (60.0%) than HPV-negative women (p = 0.04).

CONCLUSIONS

TT virus excretion in the female genital tract of human immunodeficiency virus-infected women is common, further supporting sexual transmission of this virus.
