[Show abstract][Hide abstract] ABSTRACT: Marijuana use was recently reported to have a positive cross-sectional association with human papillomavirus (HPV)-related head and neck cancer. Laboratory data suggest that marijuana could have an immunomodulatory effect. Little is known, however, regarding the effects of marijuana use on cervical HPV or neoplasia. Therefore, we studied the natural history (i.e., prevalence, incident detection, clearance/persistence) of cervical HPV and cervical neoplasia (i.e., squamous intraepithelial lesions; SIL) in a large prospective cohort of 2,584 HIV-seropositive and 915 HIV-seronegative women. Marijuana use was classified as ever/never, current/not current, and by frequency and duration of use. No positive associations were observed between use of marijuana, and either cervical HPV infection or SIL. The findings were similar among HIV-seropositive and HIV-seronegative women, and in tobacco smokers and nonsmokers. These data suggest that marijuana use does not increase the burden of cervical HPV infection or SIL.

Tratamos de determinar si los metodos estandar de diagnostico de la vaginitis muestran un comportamiento similar en mujeres infectadas por el VIH y en mujeres seronegativas en riesgo. Materiales y metodos. Realizamos comparaciones apareadas a lo largo del tiempo (1994-2003) para los diversos metodos diagnosticos de la vaginosis bacteriana (VB) (puntuacion de Nugent y criterios de Amsel), la candidiasis vulvovaginal (frotis con hidroxido potasico y citologia) y la tricomoniasis (cultivo, preparacion microscopica en fresco y citologia) en mujeres infectadas por el VIH y mujeres seronegativas para el VIH en riesgo de la cohorte del Women's Interagency HIV Study. Estratificamos a las pacientes en funcion de la presencia del VIH y, en el caso de las mujeres infectadas por el VIH, en funcion del recuento de linfocitos CD4+. Resultados. Para la VB y la tricomoniasis, despues del primer ano, el parametro estadistico que comparaba los metodos de diagnostico clinico con los metodos basados en analisis de laboratorio mejoro. Se observaron diferencias significativas en el parametro estadistico [kappa]global entre las mujeres infectadas por el VIH y las mujeres seronegativas para el VIH en riesgo solo en el caso de la candidiasis vulvovaginal, en la que los resultados del frotis con hidroxido potasico y de la citologia mostraban una correlacion mas estrecha en las mujeres infectadas por el VIH que en las mujeres seronegativas para el VIH en riesgo; en estas mujeres infectadas por el VIH, la concordancia mas elevada se dio con recuentos de linfocitos CD4 menores. No se observaron diferencias significativas en el parametro estadistico para los metodos diagnosticos de la VB o la tricomoniasis en funcion de la presencia del VIH ni en funcion de los estratos de recuentos de linfocitos CD4+. Conclusiones. Las pruebas estandar para el diagnostico de la VB, la candidiasis vulvovaginal y la tricomoniasis muestran un comportamiento similar en las mujeres infectadas por el VIH y en las mujeres seronegativas en riesgo. La formacion y la experiencia son aspectos cruciales para lograr que los metodos diagnosticos que requieren interpretacion por parte de un clinico sean exactos y eficaces.

[Show abstract][Hide abstract] ABSTRACT: High serum levels of insulin-like growth factor-I (IGF-I) are reported to be a risk factor for several common cancers, and recent cross-sectional data suggest a possible additional association of IGF-I with cervical neoplasia. To prospectively assess whether circulating IGF-I levels influence the natural history of oncogenic human papillomavirus (HPV), the viral cause of cervical cancer, we conducted a pilot investigation of 137 women who underwent semiannual type-specific HPV DNA PCR testing and cervical cytology. Total IGF-I and IGF binding protein-3 (IGFBP-3), the most abundant IGFBP in circulation, were measured using baseline serum specimens. Having a high IGF-I/IGFBP-3 ratio was associated with increased persistence of oncogenic HPV infection [that is, a lower rate of clearance; adjusted hazard ratio (AHR), 0.14; 95% confidence interval (95% CI), 0.04-0.57], whereas IGFBP-3 was inversely associated with both the incident detection of oncogenic HPV (AHR, 0.35; 95% CI, 0.13-0.93) and the incidence of oncogenic HPV-positive cervical neoplasia (that is, squamous intraepithelial lesions at risk of progression; AHR, 0.07; 95% CI, 0.01-0.66). These prospective data provide initial evidence that the IGF axis may influence the natural history of oncogenic HPV.

[Show abstract][Hide abstract] ABSTRACT: To compare Müllerian inhibiting substance (MIS) levels in serum obtained during the early follicular phase to those obtained randomly during the menstrual cycle. To determine whether HIV infection influences early follicular MIS levels, an early marker of ovarian aging.
A cross-sectional study.
Women's Interagency HIV Study, a multicenter prospective study.
Serum samples obtained from 263 (187 HIV infected and 76 uninfected) participants of the Women's Interagency HIV Study who reported menstrual bleeding during the preceding 6 months and who were not taking exogenous hormones.
Early follicular (cycle days 2-5) MIS samples were compared with serum samples that had been obtained without regard to menstrual cycle phase. Comparison samples were obtained within 6 weeks before or within 3 to 6 months after the early follicular samples. Early follicular FSH, E(2), inhibin B, and MIS levels were also compared between the HIV infected and uninfected women.
Correlation between early follicular MIS and prior and subsequent samples. Comparison of serum markers of ovarian reserve between HIV positive and negative women.
The MIS values from early follicular and other random cycle phases were highly correlated with each other (r > 0.93). In multivariate analysis, increased age and FSH level and lower inhibin B levels were associated with lower MIS level; MIS values did not vary by HIV serostatus.
Without regard to cycle phase, MIS was similar during early follicular phase and highly correlated with early follicular FSH and inhibin B in women with and without HIV. Measurement of serum MIS offers a simplified method of determining ovarian reserve using specimens obtained without menstrual phase timing. Furthermore, using biologic measures of reproductive aging, we found no evidence that HIV infection influences ovarian aging.

[Show abstract][Hide abstract] ABSTRACT: We sought to determine whether the standard diagnostic methods for vaginitis behave similarly among HIV-infected and at-risk seronegative women.
We performed pairwise comparisons over time (1994-2003) for the different diagnostic methods for bacterial vaginosis (BV) (Nugent score and Amsel criteria), vulvovaginal candidiasis (potassium hydroxide smear and Pap smear), and trichomoniasis (culture, wet mount, and Pap smear) among HIV-infected and at-risk HIV seronegative women in the Women's Interagency HIV Study cohort. We stratified subjects by HIV status and among the HIV-infected women by CD4+ cell count strata.
For BV and trichomoniasis, kappa statistics comparing clinical diagnostic methods to laboratory-based methods improved after the first year. Significant differences in overall kappa statistics between HIV-infected and at-risk HIV-seronegative women were found only for vulvovaginal candidiasis where potassium hydroxide smear and Pap smear findings were more tightly correlated among HIV-infected women than among at-risk HIV-seronegative women; among these HIV-infected women, concordance was highest at lower CD4 cell counts. No significant differences in kappa statistics were found for the diagnostic methods of BV or trichomoniasis neither by HIV status nor CD4 cell count strata.
The standard diagnostic tests for BV, vulvovaginal candidiasis, and trichomoniasis behave similarly in HIV-infected and at-risk seronegative women. Training and experience are critical for the accurate performance of the diagnostic methods that require clinician interpretation.

[Show abstract][Hide abstract] ABSTRACT: To characterize ovarian failure and prolonged amenorrhea from other causes in women who are both human immunodeficiency virus (HIV) seropositive and seronegative.
This was a cohort study nested in the Women's Interagency HIV Study, a multicenter U.S. study of HIV infection in women. Prolonged amenorrhea was defined as no vaginal bleeding for at least 1 year. A serum follicle stimulating hormone more than 25 milli-International Units/mL and prolonged amenorrhea were used to define ovarian failure. Logistic regressions, chi2, and t tests were performed to estimate relationships between HIV-infection and cofactors with both ovarian failure and amenorrhea from other causes.
Results were available for 1,431 women (1,139 HIV seropositive and 292 seronegative). More than one half of the HIV positive women with prolonged amenorrhea of at least 1 year did not have ovarian failure. When adjusted for age, HIV seropositive women were about three times more likely than seronegative women to have prolonged amenorrhea without ovarian failure. Body mass index, serum albumin, and parity were all negatively associated with ovarian failure in HIV seropositive women.
HIV serostatus is associated with prolonged amenorrhea. It is difficult to ascertain whether the cause of prolonged amenorrhea is ovarian in HIV-infected women without additional testing.

[Show abstract][Hide abstract] ABSTRACT: To evaluate changes over time in rates of bacterial vaginosis (BV), trichomoniasis (TV), and yeast vaginitis (YV) among HIV-infected and similar HIV-uninfected women.
Two thousand fifty-six HIV-infected women and 554 HIV-uninfected women were evaluated semiannually from 1994 until March 2003 in a prospective cohort study. BV was diagnosed by Gram stain, TV by wet mount, and YV by symptoms with microscopically visible hyphae or positive culture. Trends were assessed using Poisson models.
At baseline, BV was present in 42.8% and 47.0% of HIV-infected and uninfected women (P = 0.21), TV in 6.1% and 7.8% (P = 0.17), and YV in 10.0% and 3.8% (P < 0.001). Over time, rates of BV and TV decreased significantly in both groups, whereas rates of YV declined only among HIV-infected women. Risk of BV was not associated with HIV status, whereas HIV-infected women had a lower risk of TV. Highly active antiretroviral therapy (HAART) use was associated with decreased risk of all 3 infections.
: Declines in BV, TV, and YV represent decreased morbidity for HIV-infected women and, potentially, decreased risk of transmission of HIV, because each has been associated with increased genital detection of HIV.

[Show abstract][Hide abstract] ABSTRACT: Despite the low mortality and morbidity of major obstetric and gynecologic surgeries (including hysterectomy and cesarean delivery), women undergoing these procedures occasionally suffer from intractable postoperative suprapubic and groin pain. We present seven patients whose intractable pain lasted longer than 6 months and was not due to gynecologic disease or other obvious pathology.
Neuromas of the ilioinguinal, iliohypogastric, and/or genitofemoral nerves were suspected clinically and confirmed intraoperatively.
After neuroma resection, all patients reported complete and durable pain relief.
Intractable pain after obstetric or gynecologic surgery can be due to neuroma formation, and resection is therapeutic. We suggest an algorithm for the management of women with chronic intractable suprapubic or groin pain after major obstetric and gynecologic surgery.

[Show abstract][Hide abstract] ABSTRACT: To estimate the risk of and risk factors for progression among human immunodeficiency virus (HIV)-seropositive women with abnormal cervical cytology but negative colposcopy.
In a prospective cohort study, 391 HIV-seropositive and 103 seronegative women with cervical cytology read as atypical squamous cells (ASC) or low-grade squamous intraepithelial lesion (LSIL) but negative colposcopy were followed up for a mean of 4.0 years with cytology at 6-month intervals. Colposcopy was prescribed for any epithelial abnormality.
Progression to CIN2, CIN3, high-grade SIL/severe dysplasia, or cancer occurred in 47 (12%) HIV-seropositive women and 4 (4%) HIV-seronegative women (P = .02). Progression to CIN1 was seen in an additional 12 HIV-seropositive women and 1 seronegative woman. In multivariate analysis, high-risk but not low-risk HPV detection (hazard ratio [HR] 2.46-95% confidence interval [CI] 1.18-5.12, P = .02 for high risk, HR 1.41, 95% CI 0.62-3.21, P = .42 for low risk), satisfactory colposcopy (HR 2.01, 95% CI 1.11-3.65, P = .02), and non-Hispanic African-American ethnicity (HR 5.08, 95% CI 1.72-14.98, P = .003) were the only factors associated with progression, while HIV serostatus was marginally significant (HR 2.53, 95% CI 0.85-7.50, P = .09).
Human immunodeficiency virus-seropositive women with negative colposcopy after borderline cytology face a higher risk of progression than seronegative women, but the absolute risk is low and becomes nonsignificant after controlling for HPV risk type, ethnicity, and colposcopic findings. Observation is appropriate.

[Show abstract][Hide abstract] ABSTRACT: Whether the natural history of human papillomavirus (HPV) infection is affected by bacterial vaginosis (BV) or Trichomonas vaginalis (TV) infection has not been adequately investigated in prospective studies.
Human immunodeficiency virus 1 (HIV-1)-infected (n=1763) and high-risk HIV-1-uninfected (n=493) women were assessed semiannually for BV (by Nugent's criteria), TV infection (by wet mount), type-specific HPV (by polymerase chain reaction with MY09/MY11/HMB01 HPV primers), and squamous intraepithelial lesions (SIL) (by cytological examination). Sexual history was obtained from patient report at each visit. Risk factors for prevalent and incident HPV infection and SIL were evaluated by use of multivariate models.
BV was associated with both prevalent and incident HPV infection but not with duration of HPV infection or incidence of SIL. TV infection was associated with incident HPV infection and with decreased duration and lower prevalence of HPV infection. TV infection had no association with development of SIL. Effects of BV and TV infection were similar in HIV-1-infected and high-risk HIV-1-uninfected women. HIV-1 infection and low CD4(+) lymphocyte count were strongly associated with HPV infection and development of SIL.
BV and TV infection may increase the risk of acquisition (or reactivation) of HPV infection, as is consistent with hypotheses that the local cervicovaginal milieu plays a role in susceptibility to HPV infection. The finding that BV did not affect persistence of HPV infection and that TV infection may shorten the duration of HPV infection helps explain the lack of effect that BV and TV infection have on development of SIL.

[Show abstract][Hide abstract] ABSTRACT: We sought to estimate rates of progression and regression of grade 1 cervical intraepithelial neoplasia (CIN 1) among women with human immunodeficiency virus (HIV).
In a multicenter prospective cohort study, HIV-seropositive and HIV-seronegative women were evaluated colposcopically after receiving an abnormal cytology test result between November 1994 and September 2002. Women with CIN 1 were included, except those who had undergone hysterectomy, cervical therapy, or had CIN 2-3 or cervical cancer. Those women who were included were followed cytologically twice yearly, with colposcopy repeated for atypia or worse.
We followed 223 women with CIN 1 (202 HIV seropositive and 21 HIV seronegative) for a mean of 3.3 person-years. Progression occurred in 8 HIV-seropositive women (incidence density, 1.2/100 person-years; 95% confidence interval [CI] 0.5-2.4/100 person-years) and in no HIV seronegative women. Regression occurred in 66 (33%) HIV-seropositive women (13/100 person-years, 95% CI 10-16/100 person-years) versus 14 (67%) seronegative women (32/100 person-years, relative risk 0.40, 95% CI 0.25-0.66; P < .001). In multivariate analysis, regression was associated with human papillomavirus (HPV) detection (hazard ratio [HR] for low risk 0.28, 95% CI 0.13-0.61, P = .001; and for high-risk 0.34, 95% CI 0.20-0.55, P < .001 versus no HPV detected) and Hispanic ethnicity (HR 0.48, 95% CI 0.230.98; P = .04); HIV serostatus was only marginally linked to regression (HR 0.52, 95% CI 0.27-1.03; P = .06), but seropositive women were less likely to regress when analysis was limited to 146 women with HPV detected at CIN 1 diagnosis (HR 0.18, 95% CI 0.05-0.62; P = .006).
Grade 1 cervical intraepithelial neoplasia infrequently progresses in women with HIV. Thus, observation appears safe absent other indications for treatment.

[Show abstract][Hide abstract] ABSTRACT: Women infected with human immunodeficiency virus (HIV) have an increased risk of persistent squamous intraepithelial lesions (SILs) of the cervix. We assessed the association between use of highly active antiretroviral therapy (HAART) and regression of SIL in HIV-infected women enrolled in the Women's Interagency HIV Study, a large, multicenter, prospective cohort study.
Of 2059 HIV-infected participants, 312 HIV-infected women had normal cervical cytology at baseline and were subsequently diagnosed during 7 years of follow-up with incident SIL. Pap smears, CD4+ T-cell counts, and information regarding use of HAART were obtained every 6 months. The outcome of interest was lesion regression, defined as two consecutive normal Pap smears 6 months apart. Incidence rates of SIL regression were computed among person-years at risk, both before and after HAART initiation. All statistical tests were two-sided.
Of 312 women, 141 had lesions that regressed to normal cytology, with a median time to regression of 2.7 years. Overall, the incidence of regression increased (P(trend) =.002) over time after HAART was introduced. At incident SIL, median CD4+ T-cell counts were lower in women whose lesions did not regress than in women whose lesions regressed (230 versus 336 cells/microL; P<.01). Before HAART was introduced, the rate of lesion regression was 0.0% (95% confidence interval [CI' = 0.0% to 2.4%). After HAART was introduced, the rate was 12.5% (95% CI = 9.9% to 15.1%) and was related to post-HAART CD4+ T-cell counts (P(trend) =.002).
HAART use was associated with increased regression of SIL among HIV-infected women, and among women who used HAART, increased CD4+ T-cell counts were associated with a greater likelihood of regression. However, the majority of cervical lesions among HIV-infected women, even among individuals who used HAART, did not regress to normal.

[Show abstract][Hide abstract] ABSTRACT: The purpose of this study was to determine the incidence and predictors of genital warts and vulvar intraepithelial neoplasia among women with the human immunodeficiency virus.
This was a multicenter prospective cohort study comprised of women without warts or vulvar intraepithelial neoplasia at baseline who underwent CD4 count, human immunodeficiency virus RNA measurement, examination, Papanicolaou test, and biopsy, as indicated, every 6 months. Human papillomavirus DNA typing was examined at baseline.
The incidence of warts among women who were human immunodeficiency virus seronegative was 1.31 versus 5.01 per 100 person-years among women who were seropositive (P < .001). Incidence of vulvar intraepithelial neoplasia among women who were seronegative was 1.31 versus 4.67 per 100 person-years among women who were seropositive (P < .001). In multivariable analysis, warts were associated with highly active antiretroviral therapy (relative hazard, 0.76), CD4 count (relative hazard, 0.91/100 cell/cm(2) increase), acquired immunodeficiency syndrome (relative hazard, 1.25), abnormal Papanicolaou test results (relative hazard, 2.18), high- or medium-risk human papillomavirus types (relative hazard, 1.91), low-risk human papillomavirus types (relative hazard, 1.48), smoking (relative hazard, 1.43), having 1 child (relative hazard, 1.54), and age (relative hazard, 0.74/10 years). Vulvar intraepithelial neoplasia was linked to highly active antiretroviral therapy (relative hazard, 0.65), CD4 count (relative hazard, 0.92), abnormal Papanicolaou test results (relative hazard, 16.03), high- or medium-risk human papillomavirus types (relative hazard, 1.37), and age (relative hazard, 0.85/10 years).
Warts and vulvar intraepithelial neoplasia are common among women with human immunodeficiency virus. Highly active antiretroviral therapy decreases their incidence.

[Show abstract][Hide abstract] ABSTRACT: To determine incidence, progression, and regression rates for abnormal cervical cytology and their correlates among women with HIV.
In a multicenter prospective cohort study conducted October 1, 1994, through September 30, 1999 at university, public, and private medical centers and clinics, 1639 HIV-seropositive and 452 seronegative women were evaluated every 6 months for up to 5 years using history, cervical cytology, T-cell subsets, and quantitative plasma HIV RNA. Human papillomavirus (HPV) typing at baseline was determined by polymerase chain reaction. Cytology was read using the Bethesda system, with any smear showing at least atypia considered abnormal. Poisson regression identified factors associated with incident cytologic abnormalities whereas logistic regression identified those associated with progression and regression after an abnormality.
At least one abnormal smear was found during all of follow-up among 73.0% of HIV-seropositive patients and 42.3% of seronegatives (p <.001). Only 5.9% of seropositives ever developed high-grade lesions, and the proportion with high-grade findings did not rise over time. Incidence of atypical squamous cells of uncertain significance (ASCUS) or more severe lesions among HIV-seropositive patients and seronegative patients was 26.4 and 11.0/100 woman-years (rate ratio [RR], 2.4; 95% confidence interval [CI], 1.9-3.0), whereas that of at least low-grade squamous intraepithelial lesions (SIL) was 8.9 and 2.2/100 (RR, 4.0; CI, 2.6-6.1). HIV status, detection of the presence of human papillomavirus (HPV), CD4 lymphocyte count, and HIV RNA level predicted incidence of abnormal cytology (p <.05); HPV detection and HIV RNA level predicted progression (p <.01); and HPV detection, CD4 lymphocyte count, and HIV RNA level predicted regression (p <.001). Rates of incidence, progression, and regression of abnormal cytology did not differ between HIV seronegative women and seropositive women with CD4 lymphocyte counts >200/mm(3) and HIV RNA levels <4000/ml of similar HPV status.
Although HIV infected women were at high risk for abnormal cytology, high-grade changes were uncommon. HIV status, HPV detection, CD4 lymphocyte count, and HIV RNA level predicted the incidence of cervical cytologic abnormalities. Progression was significantly increased only among the most immunosuppressed women, while regression was significantly reduced in all HIV seropositive women except those with the best controlled HIV disease.
