Natural history and possible reactivation of human papillomavirus in human immunodeficiency virus-positive women.

BACKGROUND: Little is known in human immunodeficiency virus (HIV)-positive women about how the combination of plasma HIV RNA level and CD4+ T-cell count is associated with the natural history of human papillomavirus (HPV) infection or about HPV reactivation--whether it occurs and with what frequency in HIV-positive women. METHODS: HIV-positive (n = 1848) and -negative (n = 514) women were assessed at semiannual visits (total person-years = 5661) for cervicovaginal HPV with polymerase chain reaction assays and for squamous intraepithelial lesions (SILs) by Pap smear. We studied the prevalent detection of HPV and SILs with generalized estimating equations and the incident detection and persistence of HPV and SILs with multivariable Cox models. All statistical tests were two-sided. RESULTS: We observed a strong interaction between the associations of CD4+ and plasma HIV RNA strata with both prevalent (P(interaction) = .002) and incident (P(interaction) = .001) detection of HPV. Indeed, the hazard ratio for incident HPV detection peaked between 4.0 and 5.0, with either a CD4+ count of less than 200 cells per mm3 or an HIV RNA level of more than 100,000 copies per mL. Although incident HPV detection in all women was associated with the number of recent sex partners (P(trend)<.001), 22% of sexually inactive HIV-positive women with a CD4+ count of less than 200 cells/mm3 also had at least one incidentally detected HPV type. The association between CD4+/HIV RNA strata and HPV persistence was statistically significantly smaller (P<.001) than for incident HPV detection. SIL prevalence, incident detection, and persistence had similar associations with CD4+/HIV RNA strata as HPV (above). CONCLUSION: In HIV-positive women, plasma HIV RNA level and CD4+ count in combination appear to have a strong and statistically interactive association with incident detection of HPV, some of which may reflect HPV reactivation (e.g., in sexually inactive women). The more moderate association between HIV coinfection and HPV persistence could partly explain why cervical cancer rates have not reached more epidemic proportions in HIV-positive women.

Factors and temporal trends associated with highly active antiretroviral therapy discontinuation in the Women's Interagency HIV Study.

We characterized factors and temporal trends associated with discontinuation of highly active antiretroviral therapy (HAART) among 936 HIV-infected women enrolled in the Women's Interagency HIV Study. A multivariate analysis of post-HAART initiation exposures found that high HIV RNA levels (relative hazard [RH] = 1.36, P < 0.001) and high depressive symptom scores (RH = 1.53, P = 0.012) were associated with HAART discontinuation. The adjusted hazard of discontinuation was higher in the 2 most recent calendar periods compared with the first (RH = 1.61, P = 0.026; RH = 1.56, P = 0.074, respectively). The increasing risk of HAART discontinuation in recent calendar periods and changes in the clinical factors associated with discontinuation reflect ongoing and dynamic shifts in the approach to HAART utilization.

Incidence of cervical squamous intraepithelial lesions associated with HIV serostatus, CD4 cell counts, and human papillomavirus test results.

CONTEXT: Recent cervical cancer screening guidelines state that the interval between screenings can be safely extended to 3 years in healthy women 30 years or older who have normal cytology results and have negative test results for oncogenic human papillomavirus (HPV) DNA. OBJECTIVE: To determine the incidence of squamous intraepithelial lesions (SILs) in HIV-seropositive women with normal cytology results, by baseline HPV DNA results. DESIGN, SETTING, AND PATIENTS: Participants were HIV-seropositive (n = 855; mean age, 36 years) and HIV-seronegative (n = 343; mean age, 34 years) US women with normal baseline cervical cytology who were enrolled in the Women's Interagency HIV Study (WIHS), a large, multi-institutional prospective cohort study. Since their recruitment during 1994-1995, WIHS participants have been followed up semi-annually with repeated Pap smears for a median of 7 years. MAIN OUTCOME MEASURE: The cumulative incidence of any SIL and high-grade SIL or cancer (HSIL+) was estimated according to baseline HPV DNA results, stratified by HIV serostatus and CD4 T-cell count. RESULTS: Development of any SIL in women with negative HPV results (both oncogenic and nononcogenic) at 2 years was as follows: in HIV-seropositive women with CD4 counts less than 200/microL, 9% (95% CI, 1%-18%); with CD4 counts between 200/muL and 500/microL, 9% (95% CI, 4%-13%); and with CD4 counts greater than 500/microL, 4% (95% CI, 1%-7%). The CIs for these estimates overlapped with those for HIV-seronegative women with normal baseline cytology who were HPV-negative (3%; 95% CI, 1%-5%), indicating that at 2 years, there were no large absolute differences in the cumulative incidence of any SIL between groups. Furthermore, no HPV-negative participants in any group developed HSIL+ lesions within 3 years. Multivariate Cox models showed that on a relative scale, the incidence of any SIL among HIV-seropositive women with CD4 counts greater than 500/microL (hazard ratio [HR], 1.2; 95% CI, 0.5-3.0), but not those with CD4 counts less than or equal to 500/microL (HR, 2.9; 95% CI, 1.2-7.1), was similar to that in HIV-seronegative women. CONCLUSION: The similar low cumulative incidence of any SIL among HIV-seronegative and HIV-seropositive women with CD4 counts greater than 500/microL and who had normal cervical cytology and HPV-negative test results suggests that similar cervical cancer screening practices may be applicable to both groups, although this strategy warrants evaluation in an appropriate clinical trial.

Effects of bacterial vaginosis and other genital infections on the natural history of human papillomavirus infection in HIV-1-infected and high-risk HIV-1-uninfected women.

BACKGROUND: 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.

Variants of human papillomaviruses 16 and 18 and their natural history in human immunodeficiency virus-positive women.

Highly oncogenic human papillomavirus (HPV) 16 and 18 variants might be expected to be particularly aggressive in HIV-positive women. The association of HPV16 and 18 variant lineages with race, human immunodeficiency virus (HIV) coinfection, CD4+ T-cell count, HIV-RNA level, time-to-clearance of HPV infection and presence of squamous intraepithelial lesions (SIL) among women in the Women's Interagency HIV Study was studied. Subjects were followed semi-annually with Pap smear and cervicovaginal lavage (CVL). HPV DNA was detected in CVLs using MY09/11 L1 PCR assay. Specimens positive for HPV16/18 underwent E6 PCR and sequencing to determine the variant present. Specimens from 195 HPV16- and 162 HPV18-positive women were classified into variant lineages based on sequencing results. African variants of HPV16 and HPV18 were significantly more prevalent among African-Americans than among Caucasians [42 versus 14 % (P=0.001) and 60 versus 13 % (P<0.001), respectively]. However, it was not possible to detect associations between the HPV16 or 18 variant lineages and other factors studied. African variants of HPV16/18 were more common in women of African descent living outside Africa, which could reflect mixing behaviours and/or immunogenetic factors. However, in a large population of HIV-infected women, the variant of HPV16 or 18 was unrelated to persistence of infection or presence of SIL. If non-European variants are more oncogenic, the effect may involve a late stage in cervical tumorigenesis.

Relationship between HIV viral load and Langerhans cells of the cervical epithelium.

AIM: To determine the relationship between the density of cervical mucosa Langerhans cells, cervical histology, and HIV viral load. METHODS: Eighty-four HIV-infected and 17 women at high risk for HIV had cervical biopsies assessed for squamous intraepithelial lesions and Langerhans cell density. Langerhans cells were identified using the S-100 immunohistochemical stain and were counted manually. Polymerase chain reaction assays were used to detect cervical human papillomavirus (HPV)-DNA. T-cell subsets were determined using immunofluorescent flow cytometry. Plasma HIV RNA levels were measured using a nucleic acid sequence-based amplification technique. The associations between cervical Langerhans cell density, cervical histology, CD4 counts, HIV viral loads, HPV-DNA detection, and smoking status were assessed using multivariate statistical models. RESULTS: In multivariate analysis among women infected with HIV, the mean Langerhans cell density per high-powered field was 4.00 among women with no detectable plasma HIV-RNA, and 1.92 among those with detectable HIV-RNA (P = 0.01). The mean cervical Langerhans cell density was increased in women with high-grade squamous intraepithelial lesions compared with those with low-grade squamous intraepithelial lesions and normal/metaplastic histology (3.87 vs 2.11; P = 0.05). Neither HPV-DNA detection, smoking status, nor CD4 count was significantly associated with Langerhans cell density. CONCLUSIONS: The decrease in cervical Langerhans cell density in women with detectable HIV-RNA suggests an impaired mucosal immune response to local infections, such as HPV. Conversely, HPV infection resulting in high-grade dysplasia might be associated with an enhanced local immune response.

Rapid HIV screening for women in labor.

Women now comprise approximately half of all HIV-infected individuals and the epidemic of pediatric HIV disease continues unabated in the developing world. The issue of mother-to-child transmission has been a major concern for public health officials since the early years of this epidemic. Not uncommonly, the first opportunity to ascertain the HIV status is when a woman presents to a hospital in labor. Rapid HIV tests can provide fast results, allowing time for the provider to offer antiretroviral therapy. Several effective antiretroviral regimens are now available for the intrapartum patient whose rapid HIV test comes back as positive. Antiretroviral therapy should be initiated as soon as possible after a positive rapid HIV test result and prior to standard confirmatory testing. This article summarizes the epidemiology of HIV and focuses on testing policies, technologies for rapid screening for HIV infection and antiretroviral regimens that can reduce the risk of perinatal transmission from the intrapartum patient whose rapid HIV test comes back positive.

In utero marijuana exposure associated with abnormal amygdala dopamine D2 gene expression in the human fetus.

BACKGROUND: Marijuana (Cannabis sativa) is the illicit drug most used by pregnant women, and behavioral and cognitive impairments have been documented in cannabis-exposed offspring. Despite the extensive use of marijuana, very limited information exists as to the consequences of prenatal cannabis exposure on the developing human brain. METHODS: We optimized an in situ hybridization histochemistry technique to visualize mRNA expression in midgestation (weeks 18-22) human fetal specimens from mothers with and without documented evidence of cannabis use during pregnancy. The cannabinoid receptor type 1 (CB(1)) and major dopamine receptor subtypes, D(1) and D(2), were examined in the striatum and mesocorticolimbic structures (amygdala and hippocampus). RESULTS: Adjusting for various covariates, we found a specific reduction, particularly in male fetuses, of the D(2) mRNA expression levels in the amygdala basal nucleus in association with maternal marijuana use. The reduction was positively correlated with the amount of maternal marijuana intake during pregnancy. No significant cannabis-related alterations were detected in the hippocampus or caudal striatum for the D(2), D(1), and CB(1) mRNA levels, although alcohol showed significant contribution to striatal D(1)/D(2) expression. CONCLUSIONS: These human fetal findings suggest that in utero cannabis exposure may impair distinct mesocorticolimbic neural systems that regulate emotional behavior.

Functional attributes of mucosal immunity in cervical intraepithelial neoplasia and effects of HIV infection.

The role of mucosal immunity in human papillomavirus (HPV)-related cervical diseases is poorly understood. To characterize the local immune microenvironment in cervical intraepithelial neoplasia (CIN) 2/3 and determine the effects of HIV infection, we compared samples from three groups: normal cervix, CIN 2/3 from immunocompetent women (HIV- CIN 2/3), and CIN 2/3 from HIV seropositive women (HIV+ CIN 2/3). CIN 2/3 lesions contained increased numbers of immune cells from both the acquired and innate arms of the immune response in stroma [CD4+ and CD8+ T cells, macrophages, mast cells, B cells, neutrophils, and natural killer (NK) cells] and dysplastic epithelium (CD4+ T cells, macrophages, and NK cells). Immune cells in CIN 2/3 expressed activation markers, as measured by interleukin-2 receptor (IL-2R) and transcription factor T bet. Interferon-gamma production was significantly up-regulated in CIN lesions and was expressed by CD4+ and CD8+ T cells and NK cells, indicating the activation of immune cells. Abundant presence of transforming growth factor-beta+ CD25+ cells in the infiltrates associated with CIN lesions, and of immature CD1a+ dendritic cells expressing IL-10 and transforming growth factor-beta, indicate that CIN is associated with an influx of immune cells that produce a mixture of proinflammatory and regulatory cytokines. In HIV+ CIN, immune cell densities (CD4+ T cells, macrophages, neutrophils, and NK cells) and expression of interferon-gamma were significantly decreased compared with HIV- CIN. Regulatory cytokines were also down-regulated in this group. Therefore, both pro- and anti-inflammatory responses present in CIN 2/3 lesions are suppressed in HIV-seropositive women.

CCR2 genotype and disease progression in a treated population of HIV type 1-infected women.

Both antiretroviral therapy and the human coreceptor polymorphism CCR2-V64I slow progression of human immunodeficiency virus type 1 (HIV-1) disease. To examine the effect of V64I on disease progression in patients receiving therapy, we determined CCR2 genotypes in the Women's Interagency HIV Study cohort. We studied 2047 HIV-1-infected women, most of whom initiated treatment during the study. No association was seen between CCR2 genotype and either disease progression or therapeutic response, suggesting that the benefits of treatment most likely overshadow the salutary effects of the V64I polymorphism.

Highly active antiretroviral therapy and cervical squamous intraepithelial lesions in human immunodeficiency virus-positive women.

BACKGROUND: 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. METHODS: 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. RESULTS: 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). CONCLUSIONS: 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.

Relationship between smoking and human papillomavirus infections in HIV-infected and -uninfected women.

Background. Smoking may increase the risk of cervical cancer, a disease that is related to human papillomavirus (HPV) infection. However, the effects of smoking on the natural history of HPV are poorly understood, especially in women coinfected with human immunodeficiency virus (HIV).Methods. HIV-infected (n=1797) and HIV-uninfected (n=496) women were assessed every 6 months for type-specific HPV DNA. Smoking status was self-reported. Covariates included age, parity, sexual behavior, HIV load, CD4(+) T cell count, and antiretroviral therapy.Results. Smoking was positively associated with HPV prevalence at baseline in HIV-infected women (P=.002) and was significantly associated with type-specific HPV detection (e.g., type 18, odds ratio [OR], 2.45; 95% confidence interval [CI], 1.86-3.22). In Cox models, detection of HPV was significantly associated with smoking in HIV-infected women (relative hazard [RH], 1.33; 95% CI, 1.10-1.60; P=.003), but HPV persistence was not (RH, 0.97; 95% CI, 80-1.16; P=.72). The overall likelihood of acquiring persistent HPV was higher in smokers (OR, 1.39; 95% CI, 1.05-1.86; P=.023) because of greater incidence.Conclusions. Among HIV-infected women, smoking is associated with a significantly higher prevalence and incidence of HPV infection. Smoking during HIV infection may alter the natural history of HPV infection and increase the risk of cervical disease.

The prognostic importance of changes in CD4+ cell count and HIV-1 RNA level in women after initiating highly active antiretroviral therapy.

BACKGROUND: The prognostic value of CD4+ cell counts and HIV-1 RNA levels attained after the initiation of highly active antiretroviral therapy (HAART) compared with before the initiation of HAART has not been well defined. OBJECTIVE: To determine the prognostic value for clinical outcomes of CD4+ cell counts and HIV-1 RNA levels attained after initiating therapy. DESIGN: Prospective cohort study. SETTING: Women's Interagency HIV Study. PATIENTS: 1132 participants in the Women's Interagency HIV Study. MEASUREMENTS: HIV-1 RNA level, CD+ cell counts, AIDS-defining illness, and death. RESULTS: In multivariate analyses with a median follow-up of 3.9 years, women with CD4+ cell counts of less than 0.200 x 10(9) cells/L compared with women with CD4+ cell counts of greater than 0.350 x 10(9) cells/L after HAART initiation had a relative hazard of death from all causes of 2.66 (95% CI, 1.42 to 4.99) and a relative hazard of death from AIDS of 47.61 (CI, 5.69 to 398.40). The relative hazard of all-cause death was 3.44 (CI, 1.67 to 7.09) in women with RNA levels of more than 10 000 copies/mL compared with women with attained RNA levels of less than 80 copies/mL. The relative hazard of AIDS-related or all-cause death did not increase for women with post-HAART CD4+ cell counts between 0.200 and 0.350 x 10(9) cells/L compared with women with CD4+ cell counts of greater than 0.350 x 10(9) cells/L. Also, the relative hazard did not increase in women with post-HAART HIV-1 RNA levels between 80 and 10 000 copies/mL compared with women with post-HAART HIV-1 RNA levels of less than 80 copies/mL. Of the laboratory markers, only the post-HAART CD4+ cell count and HIV-1 RNA level were predictive of new AIDS-defining illness. CONCLUSION: Post-HAART laboratory markers predicted death and new AIDS-defining illness. Pre-HAART CD4+ cell count and HIV-1 RNA level were not predictive of clinical outcomes if adjusted for values attained after HAART initiation, suggesting that even advanced immune suppression can be overcome with HAART that results in CD4+ cell counts of greater than 0.200 x 10(9) cells/L and RNA levels of less than 10 000 copies/mL.

Pregnancy rates and predictors of conception, miscarriage and abortion in US women with HIV.

OBJECTIVE: To determine frequency and outcomes of pregnancy in US women with HIV before and after introduction of highly active antiretroviral therapy (HAART). DESIGN: Prospective cohort study at six US centers. METHODS: HIV seropositive and at-risk seronegative women reported pregnancy outcomes at 6-month intervals during the period 1 October 1994 to 31 March 2002. Outcomes were tabulated and pregnancy rates calculated. Logistic regression defined outcome correlates. RESULTS: Pregnancy rates were 7.4 and 15.2 per 100 person-years in seropositive and seronegative women, respectively (P < 0.0001). Among seropositives, 119 (36%) pregnancies ended in live birth, six (2%) in stillbirth, 126 (36%) in abortion, 83 (24%) in miscarriage, 16 (5%) in ectopic pregnancy, and two (1%) in other outcomes (P = nonsignificant versus seronegatives). Independent baseline correlates of conception in seropositives included younger age [odds ratio (OR), 1.20; 95% confidence interval (CI), 1.16-1.23], prior abortion (OR, 1.79; 95% CI, 1.25-2.63), lower HIV RNA levels (OR, 1.30; 95% CI, 1.10-1.54 for each log decrease), and being unmarried (OR, 1.59; 95% CI, 1.02-2.44). Baseline antiretroviral use at baseline was linked to lower conception risk (OR, 0.34; 95% CI, 0.49-0.98 for mono- or combination therapy; OR, 0.34; 95% CI, 0.03-4.28 for HAART). Abortion was less likely during the HAART era, (OR, 0.68; 95% CI, 0.35-1.33 during the early HAART era; OR, 0.46; 95% CI, 0.23-0.90 during the later HAART era, compared with before HAART). CONCLUSIONS: Women with HIV were less likely to conceive than at-risk uninfected women, but pregnancy outcomes were similar. Abortion became less common after the introduction of HAART.

Low incidence of invasive cervical cancer among HIV-infected US women in a prevention program.

OBJECTIVE: To measure the incidence of invasive cervical cancer (ICC) in US women infected with HIV. DESIGN: Multicenter prospective cohort study, conducted between October 1994, and September 2001. SETTING: HIV research centers operating as six urban consortia in the Women's Interagency HIV Study. SUBJECTS: A total of 2131 women (462 HIV seronegative, 1661 HIV seropositive, and eight seroconverters). Women with a history of hysterectomy or of cervical cancer at baseline evaluation were excluded. INTERVENTION: Cervical cytology obtained at 6-month intervals, with a colposcopy referral threshold of atypia, followed by individualized treatment. MAIN OUTCOME MEASURE: ICC diagnoses obtained from study databases and regional cancer registries and confirmed by a gynecologic pathologist. RESULTS: No incident ICC were observed in HIV seronegative women during 2375 woman-years of observation. During 8260 woman-years of observation, eight putative incident cases of cervical cancer were identified in HIV seropositive women, but only one was confirmed, yielding an incidence rate of 1.2/10 000 woman-years (95% confidence interval, 0.3-6.7/10 000 woman-years). The difference in incidence between HIV seropositive and seronegative women was not significant (P = 1.0). CONCLUSION: ICC is uncommon in HIV-infected US women participating in a regular prevention program.

Effect of antiretroviral therapy on the incidence of genital warts and vulvar neoplasia among women with the human immunodeficiency virus.

OBJECTIVE: 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. STUDY DESIGN: 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. RESULTS: 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). CONCLUSION: Warts and vulvar intraepithelial neoplasia are common among women with human immunodeficiency virus. Highly active antiretroviral therapy decreases their incidence.

Depressive symptoms in the immediate postpartum period among Hispanic women in three U.S. cities.

The aim of this was to examine rates and determinants of depressive symptomatology in the immediate postpartum period among Hispanic women in the United States. A total of 3952 Hispanic women who had delivered infants (parturients) were interviewed in postpartum wards in Miami, New York City and San Francisco. Symptoms of depression were regressed onto a series of social, psychological, and socioeconomic variables. Results showed that 42.6% of participants were probable cases of depression (CES-D > or = 16). Depression was negatively associated with perceived level of social support (adjusted OR = 0.59, 95% CI: 0.53-0.67) and health insurance coverage (adjusted OR = 0.68, 95% CI: 0.49-0.95), but not with the degree of acculturation or immigration status. It was found that depressive symptoms are common among Hispanic parturients. Pregnant Hispanic women should be carefully monitored for signs of depression and appropriate preventive measures are needed.

HPV testing for triage of HIV-infected women with papanicolaou smears read as atypical squamous cells of uncertain significance.

PURPOSE: To assess the utility of testing for high-risk human papillomavirus (HPV) DNA as a triage strategy for detecting cervical intraepithelial neoplasia (CIN) grade 2/3 in women with human immunodeficiency virus-1 (HIV-1) infection and cytology read as atypical cells of uncertain significance (ASCUS). METHODS: Conventional cervical cytology and cervicovaginal lavage were obtained at 6-month intervals between October 1, 1994, and September 30, 2002, from women enrolled in the Women's Interagency HIV Study, a multicenter cohort studying the natural history of HIV in women. HPV typing was performed by PCR. HPV types 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, and 68 were classified as carrying high oncogenic risk. Women with ASCUS smears were referred for colposcopy. Analyses of the sensitivity of HPV testing were cross-sectional, using colposcopy results within 90 days of first ASCUS result. RESULTS: Of the 270 women evaluated, 7 (3%) had CIN 2, and 3 (1%) had CIN3 or adenocarcinoma in situ. High-risk HPV DNA was found in 81 (30%) of the 270 participants. The sensitivity of high-risk HPV DNA detection for CIN 2/3 was 50% (95% CI 0.19, 0.81), the specificity was 71% (95% CI 0.65, 0.76), the positive predictive value was 6% (95% CI 0.01, 0.11), and the negative predictive value was 97% (95% CI 0.95, 1.00). HPV of any risk type was found in 176 (65%) of the 270 women, including 9 of 10 women with CIN 2/3, for a sensitivity of 90% (95% CI 0.56, 1.00), a specificity of 36% (95% CI 0.30, 0.42), a positive predictive value of 5% (95% CI 0.02, 0.08), and a negative predictive value of 99% (95% CI 0.94, 1.00). CONCLUSIONS: For women with HIV and Papanicolaou smears read as ASCUS, DNA testing for high risk HPV may not be sensitive enough for clinical use.
