Dilution assessment of cervicovaginal secretions collected by vaginal washing to evaluate mucosal shedding of free human immunodeficiency virus.

چکیده
A 10 mM concentration of lithium does not interfere with reverse transcription (RT) or PCR. Sampling of cervicovaginal fluid by vaginal washing, with lithium (10 mM) in the washing buffer as a marker of dilution, may be utilized to accurately determine in HIV-infected women, by quantitative RT-PCR, the genital shedding of acellular HIV RNA at the level of the mucosa itself.

Comparison of washing and swabbing procedures for collecting genital fluids to assess cervicovaginal shedding of herpes simplex virus type 2 DNA.
Asymptomatic genital shedding of herpes simplex virus type 2 (HSV-2) DNA was evidenced by real-time PCR in 25 (13.2%) of 188 cervicovaginal lavage samples and in only 13 (6.9%) paired cervicovaginal samples from 188 HSV-2-seropositive, nonpregnant childbearing-aged human immunodeficiency virus-seronegative women living in Gabon. These observations demonstrate that cervicovaginal washing is more...

Six human immunodeficiency virus (HIV)-positive women were studied weekly over 8 weeks to detect HIV RNA in plasma and cervical secretions and proviral DNA in cervical, vaginal, and cervicovaginal lavage samples by polymerase chain reaction (PCR) amplification techniques. In cervical swab samples, cell-free HIV RNA was detected more frequently than cell-associated HIV proviral DNA (22/48 vs. 7/...

The presence of human immunodeficiency virus (HIV) in cervicovaginal secretions (CVS) may be a risk factor for perinatal transmission. CVS of 25 women were evaluated for HIV and HIV mucosal antibodies; 16 infants had gastric aspirates cultured. Maternal plasma HIV was measured by quantitative RNA polymerase chain reaction. Seven women (28%), 4 of 19 pregnant and 3 of 7 nonpregnant, had HIV in C...

OBJECTIVE To detect anti-HIV antibodies in cervicovaginal secretions of HIV-seronegative female sex workers and to evaluate whether the presence of these antibodies is associated with increased sexual exposure. METHODS A cross-sectional study was carried out at a confidential clinic for female sex workers in Abidjan, Côte d'Ivoire. The participants were 342 HIV-seronegative female sex workers...
