RESUMO

BACKGROUND: Relatively little is known about the frequency and factors associated with miscarriage among women living with HIV. OBJECTIVE: The objective of the study was to evaluate factors associated with miscarriage among women enrolled in the Women's Interagency HIV Study. STUDY DESIGN: We conducted an analysis of longitudinal data collected from Oct. 1, 1994, to Sept. 30, 2017. Women who attended at least 2 Women's Interagency HIV Study visits and reported pregnancy during follow-up were included. Miscarriage was defined as spontaneous loss of pregnancy before 20 weeks of gestation based on self-report assessed at biannual visits. We modeled the association between demographic, behavioral, and clinical covariates and miscarriage (vs live birth) for women overall and stratified by HIV status using mixed-model logistic regression. RESULTS: Similar proportions of women living with and without HIV experienced miscarriage (37% and 39%, respectively, P = .638). In adjusted analyses, smoking tobacco (adjusted odds ratio, 2.0), alcohol use (adjusted odds ratio, 4.0), and marijuana use (adjusted odds ratio, 2.0) were associated with miscarriage. Among women living with HIV, low HIV viral load (<4 log10 copies/mL) (adjusted odds ratio, 0.5) and protease inhibitor (adjusted odds ratio, 0.4) vs the nonuse of combination antiretroviral therapy use were protective against miscarriage. CONCLUSION: We did not find an increased odds of miscarriage among women living with HIV compared with uninfected women; however, poorly controlled HIV infection was associated with increased miscarriage risk. Higher miscarriage risk among women exposed to tobacco, alcohol, and marijuana highlight potentially modifiable behaviors. Given previous concern about antiretroviral therapy and adverse pregnancy outcomes, the novel protective association between protease inhibitors compared with non-combination antiretroviral therapy and miscarriage in this study is reassuring.

RESUMO

To estimate the incidence of invasive cervical cancer (ICC) across up to 21 years of follow-up among women with human immunodeficiency virus (HIV) and to compare it to that among HIV-uninfected women, we reviewed ICC diagnoses from a 20-year multi-site U.S. cohort study of HIV infected and uninfected women who had Pap testing every 6 months. Incidence rates were calculated and compared to those in HIV-negative women. Incidence ratios standardized to age-, sex-, race-, and calendar-year specific population rates were calculated. After a median follow-up of 12.3 years, four ICCs were confirmed in HIV seropositive women, only one in the last 10 years of observation, and none in seronegative women. The ICC incidence rate did not differ significantly by HIV status (HIV seronegative: 0/100,000 person-years vs. HIV seropositive: 19.5/100,000 person-years; p = 0.53). The standardized incidence ratio for the HIV-infected WIHS participants was 3.31 (95% CI: 0.90, 8.47; p = 0.07). Although marginally more common in women without HIV, for those with HIV in a prevention program, ICC does not emerge as a major threat as women age.

RESUMO

BACKGROUND: Pregnancy may increase a woman's susceptibility to HIV. Maternal HIV acquisition during pregnancy and lactation is associated with increased perinatal and lactational HIV transmission. There are no published reports of preexposure prophylaxis use after the first trimester of pregnancy or during lactation. OBJECTIVE: The purpose of this study was to report the use of preexposure prophylaxis and to identify gaps in HIV prevention services for women who were at substantial risk of HIV preconception and during pregnancy and lactation at 2 United States medical centers. STUDY DESIGN: Chart review was performed on women who were identified as "at significant risk" for HIV acquisition preconception (women desiring pregnancy) and during pregnancy and lactation at 2 medical centers in San Francisco and New York from 2010-2015. Women were referred to specialty clinics for women who were living with or were at substantial risk of HIV. RESULTS: Twenty-seven women who were identified had a median age of 27 years. One-half of the women had unstable housing, 22% of the women had ongoing intimate partner violence, and 22% of the women had active substance use. Twenty-six women had a male partner living with HIV, and 1 woman had a male partner who had sex with men. Of the partners who were living with HIV, 73% (19/26) were receiving antiretroviral therapy, and 42% (11/26) had documented viral suppression. Thirty-nine percent (10/26) of partners had known detectable virus, and 19% (5/26) had unknown viral loads. Women were identified by clinicians, health educators, and health departments. Approximately one-third of the women were identified preconception (8/27); the majority of the women were identified during pregnancy (18/27) with a median gestational age of 20 weeks (interquartile range, 11-23), and 1 woman was identified in the postpartum period. None of the pregnant referrals had received safer conception counseling to reduce HIV transmission. Twenty-six percent of all women (7/27) were eligible for postexposure prophylaxis at referral, of whom 57% (4/7) were offered postexposure prophylaxis. In 30% (8/27), the last HIV exposure was not assessed and postexposure prophylaxis was not offered. The median time from identification as "at substantial risk" to consultation was 30 days (interquartile range, 2-62). Two women were lost to follow up before consultation. One woman who was identified as "at significant risk" was not referred because of multiple pregnancy complications. She remained in obstetrics care and was HIV-negative at delivery but was lost to follow up until 10 months after delivery when she was diagnosed with HIV. No other seroconversions were identified. Of referrals who presented and were offered preexposure prophylaxis, 67% women (16/24) chose to take it, which was relatively consistent whether the women were preconception (5/8), pregnant (10/15), or after delivery (1/1). Median length of time on preexposure prophylaxis was 30 weeks (interquartile range, 20-53). One-half of women (10/20) who were in care at delivery did not attend a postpartum visit. CONCLUSION: Women at 2 United States centers frequently chose to use preexposure prophylaxis for HIV prevention when it was offered preconception and during pregnancy and lactation. Further research and education are needed to close critical gaps in screening for women who are at risk of HIV for pre- and postexposure prophylaxis eligibility and gaps in care linkage before and during pregnancy and lactation. Postpartum women are particularly vulnerable to loss-to-follow-up and miss opportunities for safe and effective HIV prevention.

RESUMO

BACKGROUND: To evaluate the effects of HIV viral load, measured cross-sectionally and cumulatively, on the risk of miscarriage or stillbirth (pregnancy loss) among HIV-infected women enrolled in the Women's Interagency HIV Study between 1994 and 2013. METHODS: We assessed three exposures: most recent viral load measure before the pregnancy ended, log10 copy-years viremia from initiation of antiretroviral therapy (ART) to conception, and log10 copy-years viremia in the two years before conception. RESULTS: The risk of pregnancy loss for those with log10 viral load >4.00 before pregnancy ended was 1.59 (95% confidence interval (CI): 0.99, 2.56) times as high as the risk for women whose log10 viral load was ≤1.60. There was not a meaningful impact of log10 copy-years viremia since ART or log10 copy-years viremia in the two years before conception on pregnancy loss (adjusted risk ratios (aRRs): 0.80 (95% CI: 0.69, 0.92) and 1.00 (95% CI: 0.90, 1.11), resp.). CONCLUSIONS: Cumulative viral load burden does not appear to be an informative measure for pregnancy loss risk, but the extent of HIV replication during pregnancy, as represented by plasma HIV RNA viral load, predicted loss versus live birth in this ethnically diverse cohort of HIV-infected US women.

RESUMO

To estimate the long term cumulative risk for cervical intraepithelial neoplasia grade 3 or worse after an abnormal cervical Pap test and to assess the effect of HIV infection on that risk. Participants in the Women's Interagency HIV Study were followed semiannually for up to 10 years. Pap tests were categorized according to the 1991 Bethesda system. Colposcopy was prescribed within 6 months of any abnormality. Risk for biopsy-confirmed CIN3 or worse after abnormal cytology and at least 12 months follow-up was assessed using Kaplan-Meier curves and compared using log-rank tests. Risk for CIN2 or worse was also assessed, since CIN2 is the threshold for treatment. After a median of 3 years of observation, 1,947 (85%) women subsequently presented for colposcopy (1,571 [81%] HIV seropositive, 376 [19%] seronegative). CIN2 or worse was found in 329 (21%) of HIV seropositive and 42 (11%) seronegative women. CIN3 or worse was found in 141 (9%) of seropositive and 22 (6%) seronegative women. In multivariable analysis, after controlling for cytology grade HIV seropositive women had an increased risk for CIN2 or worse (H.R. 1.66, 95% C.I 1.15, 2.45) but higher risk for CIN3 or worse did not reach significance (H.R. 1.33, 95% C.I. 0.79, 2.34). HIV seropositive women with abnormal Paps face a marginally increased and long-term risk for cervical disease compared to HIV seronegative women, but most women with ASCUS and LSIL Pap results do not develop CIN2 or worse despite years of observation.

RESUMO

BACKGROUND: The impact of highly active antiretroviral therapy (HAART) on the natural history of human papillomavirus (HPV) remains uncertain following conflicting reports. Prior studies, however, did not consider patients' adherence to their regimens or HAART effectiveness (viral suppression). METHODS: Human immunodeficiency virus (HIV)-positive women (N = 286) who initiated HAART during follow-up in a prospective cohort were assessed semiannually for HPV infection (by polymerase chain reaction) and squamous intraepithelial lesions (SILs). Adherence was defined as use of HAART as prescribed > or = 95% of the time, and effective HAART was defined as suppression of HIV replication. The prevalence, incident detection, and clearance of HPV infection and/or SILs before versus after HAART initiation were compared (using women as their own comparison group). RESULTS: HAART initiation among adherent women was associated with a significant reduction in prevalence (odds ratio, 0.60 [95% confidence interval {CI}, 0.44-0.81]; P = .001), incident detection of oncogenic HPV infection (hazard ratio [HR], 0.49 [95% CI, 0.30-0.82]; P = .006), and decreased prevalence and more rapid clearance of oncogenic HPV-positive SILs (HR, 2.35 [95% CI, 1.07-5.18]; P = .03). Effects were smaller among nonadherent women. The associations of HPV infection and/or SILs with HAART effectiveness were fairly similar to those with HAART adherence. CONCLUSION: Effective and adherent HAART use is associated with a significantly reduced burden of HPV infection and SILs; this may help explain why rates of cervical cancer have not increased during the HAART era, despite greater longevity.

RESUMO

OBJECTIVE: To estimate the frequency of and trends in abnormal Pap test results in women with human immunodeficiency virus (HIV) and HIV-uninfected women. METHODS: In a cohort study of HIV-infected and uninfected women, Pap tests were obtained every 6 months. Results of atypical squamous cells of undetermined significance (ASC-US) or worse were considered abnormal. RESULTS: Over a median of 8.4 years, 23,843 Pap tests were obtained from 1,931 HIV-positive women with 6,828 Pap tests from 533 HIV-negative women (13 women seroconverted during the study). Among women with HIV, Pap test results were ASC-US in 4,462 (19%), low-grade squamous intraepithelial lesion (LSIL) in 3,199 (13%), high-grade squamous intraepithelial lesion (HSIL) in 267 (1%), and cancer in 11 (0.05%). The incidence of abnormal Pap test results was 179 in 1,000 person-years for HIV-positive and 75 in 1,000 person-years for HIV-negative women (incidence rate ratio 2.4, 95% confidence interval 2.0-2.8). The incidence of HSIL or cancer was 4.4 in 1,000 person-years for HIV-positive and 1.3 in 1,000 person-years for HIV-negative women (incidence rate ratio 3.4, 95% confidence interval 1.2-9.5). CONCLUSION: Among women with HIV in a cervical cancer prevention program, Pap test abnormalities are common, but high-grade abnormalities are infrequent. LEVEL OF EVIDENCE: II.

RESUMO

BACKGROUND: Eliminating mother-to-child transmission (MTCT) of HIV has been one of New York State's public health priorities, and the goal has been virtually accomplished by meeting criteria established by the Centers for Disease Control and Prevention. METHODS: We use a return on investment (ROI) approach, from the perspective of the state, to compare expenditures incurred to prevent MTCT of HIV in NYS during the period 1998-2013 to benefits realized, as expressed as HIV treatment costs saved from averting an estimated number of HIV infections among newborns. Extrapolating from the 11.5% incidence rate of HIV-infected newborns in 1997, we projected the number of cases of MTCT of HIV that were averted over the 16-year period. A published estimate of lifetime HIV treatment costs was used to estimate HIV treatment costs saved from the averted infections; expenditures for clinical protocols and other services directly associated with preventing MTCT of HIV were also estimated. The ROI was then calculated by dividing program benefits by the expenditures incurred to achieve these benefits. RESULTS: We estimate that 898 cases of MTCT of HIV were averted between 1998 and 2013, resulting in a savings of $321.03 million in HIV treatment costs. Expenditures to achieve these benefits totaled $81.07 million, yielding an ROI of $3.96. CONCLUSIONS: Aside from the human suffering from MTCT of HIV that is averted, expenditures for treatment protocols and interventions to prevent MTCT of HIV are relatively inexpensive and can result in almost 4 times their value in HIV treatment cost savings realized.

RESUMO

PURPOSE: To describe changes in knowledge of cervical cancer prevention, human papillomavirus (HPV), and HPV vaccination among women at high risk for cervical cancer in the first five years after introduction of HPV vaccination. METHODS: In 2007, 2008-9, and 2011, women in a multicenter U.S. cohort study completed 44-item self-report questionnaires assessing knowledge of cervical cancer prevention, HPV, and HPV vaccination. Results across time were assessed for individuals, and three study enrollment cohorts were compared. Knowledge scores were correlated with demographic variables, measures of education and attention, and medical factors. Associations were assessed in multivariable models. RESULTS: In all, 974 women completed three serial questionnaires; most were minority, low income, and current or former smokers. The group included 652 (67%) HIV infected and 322 (33%) uninfected. Summary knowledge scores (possible range 0-24) increased from 2007 (12.8, S.D. 5.8) to 2008-9 (13.9, S.D. 5.3, P < 0.001) and to 2011 (14.3, S.D 5.2, P < 0.0001 vs 2007 and <0.04 vs 2008-9). Higher knowledge scores at first and follow-up administration of questionnaires, higher income, and higher education level were associated with improved knowledge score at third administration. Women not previously surveyed had scores similar to those of the longitudinal group at baseline. CONCLUSION: Substantial gaps in understanding of HPV and cervical cancer prevention exist despite years of health education. While more effective educational interventions may help, optimal cancer prevention may require opt-out vaccination programs that do not require nuanced understanding.

RESUMO

BACKGROUND: Women with HIV and prior exposure to combination antiretroviral therapy (cART) solely for prevention of mother-to-child transmission (pMTCT) need to know whether they can later be treated successfully with a commonly used regimen of efavirenz (EFV) and coformulated emtricitabine (FTC) and tenofovir disoproxil fumarate (TDF). METHODS: Nonpregnant women with plasma HIV-1 RNA of ≥500 copies per milliliter, previously cART exposed for pMTCT only, were eligible if they were off ART for ≥24 weeks before entry, were without evidence of drug resistance on standard genotyping, and were ready to start EFV plus FTC/TDF. The primary endpoint was virologic response (defined as plasma HIV RNA <400 copies/mL) at 24 weeks. RESULTS: Fifty-four women were enrolled between October 2007 and December 2009; 52 of 54 completed 24 weeks of follow-up. Median baseline CD4 T-cell count was 265/mm and baseline plasma HIV-1 RNA was 4.6 log10 copies per milliliter. Median prior cART duration was 14 weeks, and median time elapsed from the last pMTCT dose to entry was 22 months. Virologic response at 24 weeks was observed in 42 of 52 women or 81% (exact 95% confidence interval: 68% to 90%). There were no differences in response by country, by number, or class of prior pMTCT exposures. Although confirmed virologic failure occurred in 8 women, no virologic failures were observed in women reporting perfect early adherence. CONCLUSIONS: In this first prospective clinical trial studying combination antiretroviral retreatment in women with a history of pregnancy-limited cART, the observed virologic response to TDF/FTC and EFV at 24 weeks was 81%. Virologic failures occurred and correlated with self-reported nonadherence.

RESUMO

OBJECTIVE: To estimate the accuracy of Pap testing for women who are human immunodeficiency virus (HIV)-seropositive, with a focus on negative predictive value. METHODS: Participants in the Women's Interagency HIV Study were monitored with conventional Pap tests every 6 months. After excluding those with abnormal Pap test results before study, cervical disease, or hysterectomy, women with negative enrollment Pap test results were monitored for development of precancer within 15 or 39 months, defined as a Pap test result read as high-grade squamous intraepithelial lesion, atypical glandular cells favor neoplasia, or adenocarcinoma in situ, or a cervical biopsy read as cervical intraepithelial neoplasia 2 or worse. Correlations between one or more consecutive negative Pap test results and subsequent precancer were assessed using Cox proportional hazards models. RESULTS: Among 942 HIV-infected women with negative baseline Pap test results, eight (1%) developed precancer within 15 months and 40 (4%) within 39 months. After three consecutive negative Pap test results, precancer was rare, with no cases within 15 months and 10 of 539 (2%) within 39 months. No women developed precancer or cancer within 39 months after 10 consecutive negative Pap test results. Risks for precancer within 15 months after negative Pap test result included current smoking (adjusted hazard ratio [HR] 1.5, 95% confidence interval [CI] 1.2-2.0 compared with nonsmokers), younger age (adjusted HR 1.5, 95% CI 1.1-2.1 for women aged younger than 31 years compared with older than 45 years), and lower CD4 count (adjusted HR 11.8, 95% CI 1.3-2.3 for CD4 200-500/microliter, adjusted HR 2.2, 95% CI 1.6-2.9 for CD4 less than 200/microliter, compared with CD4 more than 500/microliter). CONCLUSION: Annual Pap testing appears safe for women infected with HIV; for those with serial negative tests, longer intervals are appropriate. LEVEL OF EVIDENCE: II.

RESUMO

OBJECTIVE: To estimate the prevalence, incidence, and clearance of abnormal vaginal cytology and vaginal intraepithelial neoplasia (VAIN) in human immunodeficiency virus (HIV)-seropositive women. METHODS: Pap tests were done semiannually for 335 HIV-seropositive and 75 HIV-seronegative women with prior hysterectomy in the prospective Women's Interagency HIV Study cohort. End points included abnormal Pap test results after hysterectomy and VAIN regardless of hysterectomy. RESULTS: Over a median of 5.6 years of follow-up, vaginal Pap test results were abnormal at 1,076 (29%; 95% confidence interval [CI] 25-33%) of 3,700 visits among HIV-seropositive compared with 31 (4%; 95% CI 2-8%) of 763 visits among HIV-seronegative women (P<.001). Abnormal Pap test results included 641 atypical squamous cells of undetermined significance, 425 low-grade squamous intraepithelial lesions, and 10 high-grade squamous intraepithelial lesions in HIV-seropositive women and 28 atypical squamous cells of undetermined significance and three low-grade squamous intraepithelial lesions in HIV-seronegative women. The incidence of abnormal Pap test results after hysterectomy was 14 per 100 person-years among HIV-seropositive and two per 100 person-years among HIV-seronegative women (P<.001) and remained stable across time. The 5-year clearance rate of abnormal Pap test results was 34 per 100 person-years for HIV-seropositive and 116 per 100 person-years for HIV-seronegative women (P<.001). In multivariate regression models, women with lower CD4 counts were more likely to have and less likely to clear abnormal cytology when it occurred. The incidence of VAIN 2 or worse was 0.2 and 0.01 per 100 person-years for HIV-seropositive and HIV-seronegative women (P=.001). Two HIV-seropositive women developed stage II cancers with remission after radiotherapy. CONCLUSION: Vaginal Pap test results are often abnormal in HIV-seropositive women. Although more common than in HIV-seronegative women, VAIN 2 or worse and especially vaginal cancers are infrequent.

RESUMO

OBJECTIVES: To determine the incidence rate of, and the relative time to pregnancy by HIV status in US women between 2002 and 2009. DESIGN: The Women's Interagency HIV Study (WIHS) is an ongoing, multicenter prospective cohort study of the natural and treated history of HIV infection and related outcomes among women with and without HIV. METHODS: Eligible participants were 45 years of age or less; sexually active with male partner(s) or reported a pregnancy outcome within the past year; and never reported hysterectomy, tubal ligation, or oopherectomy. Poisson regression was conducted to compare pregnancy incidence rates over time by HIV status. Relative time to pregnancy was ascertained via Kaplan-Meier plots and generalized gamma survival analysis. RESULTS: Adjusting for age, number of male sex partners, contraception, parity, exchanging sex, and alcohol use, HIV infection was associated with a 40% reduction in the incidence rate of pregnancy [incidence rate ratio = 0.60, 95% confidence interval (CI) 0.46-0.78]. The time for HIV-infected women to become pregnant was 73% longer relative to HIV-uninfected women (relative time = 1.73, 95% CI 1.35-2.36). In addition to HIV infection, decreased parity and older age were independent predictors of lower pregnancy incidence. CONCLUSIONS: Despite the beneficial effects of modern antiretroviral therapy on survival and prevention of maternal-to-child transmission, our findings suggest that pregnancy incidence remains lower among HIV-infected women. Whether this lower incidence is due to behavioral differences or reduced biologic fertility remains an area worthy of further study.

RESUMO

OBJECTIVE: To describe the natural history of genital warts and vulvar intraepithelial neoplasia (VIN) in women with human immunodeficiency virus (HIV). METHODS: A cohort of 2,791 HIV-infected and 953 uninfected women followed for up to 13 years had genital examinations at 6-month intervals with biopsy for lesions suspicious for VIN. RESULTS: The prevalence of warts was 4.4% (5.3% for HIV-seropositive women and 1.9% for HIV-seronegative women, P<.001). The cumulative incidence of warts was 33% (95% confidence interval [CI] 30-36%) in HIV-seropositive and 9% (95% CI 6-12%) in HIV-seronegative women (P<.001). In multivariable analysis, lower CD4 lymphocyte count, younger age, and current smoking were strongly associated with risk for incident warts. Among 501 HIV-seropositive and 43 HIV-seronegative women, warts regressed in 410 (82%) seropositive and 41 (95%) seronegative women (P=.02), most in the first year after diagnosis. In multivariable analysis, regression was negatively associated with HIV status and lower CD4 count as well as older age. Incident VIN of any grade occurred more frequently among HIV-seropositive than HIV-seronegative women: 0.42 (0.33-0.53) compared with 0.07 (0.02-0.18) per 100 person-years (P<.001). Positivity for VIN 2 was found in 58 women (55 with and three without HIV, P<.001). Two women with HIV developed stage IB squamous cell vulvar cancers. CONCLUSION: Although genital warts and VIN are more common among HIV-seropositive than HIV-seronegative women, wart regression is common even in women with HIV, and cancers are infrequent.

RESUMO

OBJECTIVE: Depression is common among HIV-infected women, predicts treatment nonadherence, and consequently may impact vertical transmission of HIV. We report findings from a study evaluating preconception, pregnancy, and postpartum depressive symptoms in HIV-infected vs. at-risk, HIV-uninfected women. METHODS: We examined the prevalence and predictors of elevated perinatal (i.e., pregnancy and/or postpartum) depressive symptoms using a Center for Epidemiological Studies-Depression (CES-D) scale score of ≥16 in 139 HIV-infected and 105 HIV-uninfected women (62% African American) from the Women's Interagency HIV Study (WIHS). RESULTS: The prevalence of elevated perinatal depressive symptoms did not differ by HIV serostatus (HIV-infected 44%, HIV-uninfected 50%, p=0.44). Among HIV-infected women, the strongest predictor of elevated symptoms was preconception depression (odds ratio [OR] 5.71, 95% confidence interval [CI] 2.67-12.19, p<0.001); crack, cocaine, and/or heroin use during preconception was marginally significant (OR 3.10, 95% CI 0.96-10.01, p=0.06). In the overall sample, additional significant predictors of perinatal depression included having multiple sex partners preconception (OR 2.20, 95% CI 1.12-4.32, p=0.02), use of preconception mental health services (OR 2.51, 95% CI 1.03-6.13, p=0.04), and not graduating from high school (OR 1.92, 95% CI 1.06-3.46, p=0.03). CONCLUSIONS: Elevated perinatal depressive symptoms are common among HIV-infected and at-risk HIV-uninfected women. Depressive symptoms before pregnancy were the strongest predictor of perinatal symptoms. Findings underscore the importance of early and ongoing assessment and treatment to ensure low vertical transmission rates and improving postpregnancy outcomes for mothers and children.

RESUMO

OBJECTIVE: The purpose of this study was to compare alpha-fetoprotein, human chorionic gonadotropin, and unconjugated estriol levels in women who take protease inhibitors and those women who do not. STUDY DESIGN: This retrospective review from August 2000 to May 2003 was performed for maternal serum screen results, medication use, pregnancy, and perinatal outcomes. RESULTS: Thirty-nine women met study criteria. Sixteen women were treated with protease inhibitors, and 23 women were not treated with protease inhibitors. There was no difference in initial viral load or initial CD4 count between the groups. No difference was found for human chorionic gonadotropin and estriol levels; significantly lower alpha-fetoprotein multiples of the median were found for the women who were treated with protease inhibitors compared with the women who were not (0.97 +/- 0.32 [SD] MoM vs 1.2 +/- 0.4 MoM, respectively; P = .04). Six of 39 women (15%) had positive maternal serum screens. All the babies were normal at birth, and there were no cases of perinatal transmission of human immunodeficiency virus. CONCLUSION: Protease inhibitors are associated with lower alpha-fetoprotein levels in women who are infected with human immunodeficiency virus.
