RESUMEN
BACKGROUND: Concomitant use of efavirenz-based antiretroviral therapy and a standard-dose etonogestrel contraceptive implant led to 82% lower etonogestrel exposure when compared with women who do not receive antiretroviral therapy. The clinical impact of this reduced exposure is supported by retrospective cohort evaluations that demonstrated higher rates of unintended pregnancies when contraceptive implants were combined with efavirenz. We hypothesized that placement of 2 etonogestrel implants in those taking efavirenz-based antiretroviral therapy could increase etonogestrel exposure and improve measures of contraceptive efficacy. OBJECTIVE: This study compared the rate of ovulation and etonogestrel pharmacokinetics among women on efavirenz-based antiretroviral therapy who received 2 etonogestrel implants (136 mg; double implant group) in comparison with those who received 1 etonogestrel implant (68 mg; control group). STUDY DESIGN: This randomized, open-label study enrolled Ugandan women with regular menstrual periods who were receiving efavirenz-based antiretroviral therapy for the treatment of HIV. Participants were randomized 1:1 to the double implant or control group, and the etonogestrel implant(s) were placed in the same arm at enrollment. All participants used a copper intrauterine device to prevent pregnancy. Ovulation was evaluated by weekly serum progesterone concentrations measured over 4 consecutive weeks at months 3 (weeks 9-12), 6 (weeks 21-24), and 12 (weeks 45-48). Progesterone concentrations >3 ng/mL were interpreted as ovulation. The ovulation rate in each group was compared using Fisher's exact tests for each month and generalized estimating equations over 48 weeks. Plasma was collected at day 3 and weeks 1, 4, 12, 24, 36, and 48 after implant placement and analyzed using a validated liquid chromatography-triple quadrupole mass spectrometry method for etonogestrel. Etonogestrel concentrations were summarized as median (interquartile range) and compared between groups by geometric mean ratio with 90% confidence intervals. RESULTS: All participants (n=72) were cisgender Ugandan women with a median age of 31 years (interquartile range, 29-36), and 36 participants were enrolled in each study group. Two participants in the control group discontinued the trial; 1 at week 1 because of undetected pregnancy at entry and another at week 45 because of clinically significant depression. There were 47 ovulations over 104 person-months (45%) in 25 of 34 participants in the control group, and 2 ovulations over 108 person-months (2%) in 2 of 36 participants in the double implant group (month 3: 11 [31%] vs 0 [0%]; month 6: 17 [49%] vs 0 [0%]; month 12: 19 [56%] vs 2 [6%], respectively; all P<.001). The odds of ovulation were reduced by 97.7% (95% confidence interval, 90.1-99.5) in the double implant group over 48 weeks. At each time point, etonogestrel concentration was more than 2-fold higher in the double implant group than in the controls (geometric mean ratio, 2.30-2.83) with a geometric mean ratio of 2.83 (90% confidence interval, 1.89-3.35) at week 48. There were no differences in the adverse events between groups and no participant discontinued because of adverse events. CONCLUSION: Over 48 weeks of combined use, placing 2 etonogestrel implants suppressed ovulation and increased plasma etonogestrel exposure when compared with 1 etonogestrel implant among women on efavirenz-based antiretroviral therapy. Doubling the dose of etonogestrel during efavirenz-based antiretroviral therapy could improve contraceptive effectiveness.

There is an increasing burden of hepatitis C virus among persons of reproductive age, including pregnant and breastfeeding women, in many regions worldwide. Routine health services during pregnancy present a critical window of opportunity to diagnose and link women with hepatitis C virus infection for care and treatment to decrease hepatitis C virus-related morbidity and early mortality. Effective treatment of hepatitis C virus infection in women diagnosed during pregnancy also prevents hepatitis C virus-related adverse events in pregnancy and hepatitis C virus vertical transmission in future pregnancies. However, linkage to care and treatment for women diagnosed in pregnancy remains insufficient. Currently, there are no best practice recommendations from professional societies to ensure appropriate peripartum linkage to hepatitis C virus care and treatment. We convened a virtual Community of Practice to understand key challenges to the hepatitis C virus care cascade for women diagnosed with hepatitis C virus in pregnancy, highlight published models of integrated hepatitis C virus services for pregnant and postpartum women, and preview upcoming research and programmatic initiatives to improve linkage to hepatitis C virus care for this population. Four-hundred seventy-three participants from 43 countries participated in the Community of Practice, including a diverse range of practitioners from public health, primary care, and clinical specialties. The Community of Practice included panel sessions with representatives from major professional societies in obstetrics/gynecology, maternal fetal medicine, addiction medicine, hepatology, and infectious diseases. From this Community of Practice, we provide a series of best practices to improve linkage to hepatitis C virus treatment for pregnant and postpartum women, including specific interventions to enhance colocation of services, treatment by nonspecialist providers, active engagement and patient navigation, and decreasing time to hepatitis C virus treatment initiation. The Community of Practice aims to further support antenatal providers in improving linkage to care by producing and disseminating detailed operational guidance and recommendations and supporting operational research on models for linkage and treatment. Additionally, the Community of Practice may be leveraged to build training materials and toolkits for antenatal providers, convene experts to formalize operational recommendations, and conduct surveys to understand needs of antenatal providers. Such actions are required to ensure equitable access to hepatitis C virus treatment for women diagnosed with hepatitis C virus in pregnancy and urgently needed to achieve the ambitious targets for hepatitis C virus elimination by 2030.
RESUMEN
PURPOSE OF REVIEW: In the context of the opioid epidemic, hepatitis C virus (HCV) infection prevalence is increasing among women of reproductive age. Pregnant people with HIV/HCV coinfection may be at increased risk of adverse pregnancy and neonatal outcomes, although research in this key population is lacking. RECENT FINDINGS: Treatment with directly acting antivirals (DAAs) has transformed the clinical care for most patients with HCV. However, pregnant people were excluded from trials of these medications. A recent phase I study has shown promise with excellent safety profile for ledipasvir-sofosbuvir; demonstrating no episodes of perinatal transmission, 100% sustained virologic response, and no safety concerns. Pregnancy represents a time of maximal interaction with the healthcare system and therefore an ideal window of opportunity to cure HCV. Current observational data regarding pregnant people who are co-infected with HCV and HIV suggest poor outcomes such as increased risk of preterm birth; however, there are no prospective and well-controlled studies to fully understand the impact of HIV/HCV coinfection on pregnancy. Phase 1 studies suggest that DAAs are well-tolerated and effective during pregnancy. Only through large, prospective clinical trials will we be able to understand the interaction of HCV and HIV during pregnancy and to evaluate safety and efficacy of DAAs in this key population.

BACKGROUND: Pharmacokinetic data are lacking for progestin-releasing subdermal contraceptive implants when used with either rilpivirine- or darunavir/ritonavir-based ART. OBJECTIVES: To characterize the pharmacokinetics of etonogestrel or levonorgestrel implants when administered with these ART regimens over 48â weeks. PATIENTS AND METHODS: Two separate, parallel, three-group, non-randomized, pharmacokinetic studies evaluated either etonogestrel or levonorgestrel in women receiving rilpivirine- or darunavir-based ART compared with women without HIV (control group). Participants on ART were switched to rilpivirine-based ART with a run-in period of 6â weeks or darunavir-based ART with a run-in of 2â weeks prior to implant insertion. Plasma was collected on Day 0, and 1, 4, 12, 24, 36 and 48â weeks post-insertion. Plasma progestin concentrations were compared between ART and control groups by geometric mean ratio (GMR) and 90% CI. RESULTS: At the primary endpoint of Week 24, progestin concentrations were similar between the rilpivirine and control groups [etonogestrel: 1.18 (0.99-1.37); levonorgestrel: 1.16 (0.97-1.33)]. At Week 24, progestin exposure was higher in the darunavir groups compared with the control group [etonogestrel: 2.56 (1.69-3.28); levonorgestrel: 1.89 (1.38-2.29)]. Results remained consistent through to Week 48. No differences in etonogestrel-related adverse events were observed, but both ART groups experienced more menstrual abnormalities versus the control group with levonorgestrel. CONCLUSIONS: Etonogestrel and levonorgestrel concentrations were not altered by rilpivirine-based ART. Although progestin concentrations were higher in the ART groups containing ritonavir-boosted darunavir, no implant-related serious adverse events were observed. Both progestin-releasing implants are an appropriate contraceptive option with either rilpivirine- or darunavir/ritonavir-based ART.

BACKGROUND: Limited evidence suggests that the nonhormonal contraceptive copper intrauterine device (Cu-IUD) may increase bacterial vaginosis (BV) risk, possibly due to increased volume and duration of menses, a common side effect of Cu-IUD use. Although increases in bleeding typically resolve within 6-12 months following initiation, evaluations of the association between Cu-IUD and BV have not included more than 6 months of follow-up. METHODS: This secondary analysis of a human immunodeficiency virus type 1 prevention trial included 2585 African women ages 18-45 followed for up to 33 months. Women reported contraceptive use each month. BV was evaluated by Nugent score in 6-monthly intervals and, if clinically indicated, by Amsel criteria. Andersen-Gill proportional hazards models were used to (1) evaluate BV risk among Cu-IUD users relative to women using no/another nonhormonal contraceptive and (2) test changes in BV frequency before, while using, and following Cu-IUD discontinuation. RESULTS: BV frequency was highest among Cu-IUD users at 153.6 episodes per 100 person-years (95% confidence interval [CI]: 145.2, 162.4). In adjusted models, Cu-IUD users experienced 1.28-fold (95% CI: 1.12, 1.46) higher BV risk relative to women using no/another nonhormonal contraception. Compared to the 6 months prior to initiation, BV risk was 1.52-fold (95% CI: 1.16, 2.00) higher in the first 6 months of Cu-IUD use and remained elevated over 18 months of use (Pâ <â .05). Among women who discontinued Cu-IUD, BV frequency was similar to pre-initiation rates within 1 year. CONCLUSIONS: Cu-IUD users experienced elevated BV risk that persisted throughout use. Women and their providers may wish to consider BV risk when discussing contraceptive options.

BACKGROUND: We previously demonstrated that etonogestrel concentrations were 82% lower in women using etonogestrel contraceptive implants plus efavirenz-based ART compared with women not receiving ART. OBJECTIVES: To investigate the genetic contribution to this previously observed drug-drug interaction through studying SNPs in genes known to be involved in efavirenz, nevirapine or etonogestrel metabolism in the same group of women. PATIENTS AND METHODS: Here, we present a secondary analysis evaluating SNPs involved in efavirenz, nevirapine and etonogestrel metabolism and associated etonogestrel pharmacokinetics among 57 women, 19 not receiving ART (control group), 19 receiving efavirenz- (600 mg daily) based ART and 19 receiving nevirapine- (200 mg twice daily) based ART. Associations between patient genotype and etonogestrel pharmacokinetic parameters were determined through univariate and multivariate linear regression. This study was registered at clinicaltrials.gov (NCT02082652). RESULTS: Within the control group, CYP2B6 983 T>C was associated with 27% higher etonogestrel Cmax and 28% higher AUC0-24weeks. In the efavirenz group CYP2B6 516 G>T was associated with 43% lower etonogestrel Cmin and 34% lower AUC0-24weeks. For participants receiving nevirapine, NR1I2 63396 C>T was associated with 39% lower etonogestrel Cmin and 37% lower AUC0-24weeks. CONCLUSIONS: This study demonstrates the influence of pharmacogenetics on the extent of drug-drug interactions between etonogestrel and efavirenz- or nevirapine-based ART. Efavirenz plus the etonogestrel contraceptive implant results in a detrimental drug-drug interaction irrespective of patient genetics, which is worsened in women possessing variant alleles for these CYP2B6 SNPs.

OBJECTIVE: Reproductive hormones are known to impact innate mucosal immune function of the lower genital tract. Our objectives were to determine the effect of hormonal status on intrinsic antiviral (herpes simplex virus [HSV]-1, HSV-2, and human immunodeficiency virus [HIV]-1) activity of cervicovaginal lavage (CVL). STUDY DESIGN: CVL was collected from 165 asymptomatic women including postmenopausal women (n = 29); women not on contraception in days 1-14 (n = 26) or days 15-28 (n = 27) of the menstrual cycle; and women using the levonorgestrel intrauterine device (n = 28), depot medroxyprogesterone acetate (n = 28), or combined oral contraceptives (n = 27). The anti-HSV-1/-2 and the anti-HIV-1 activity of the CVL were measured using plaque assays and the Jurkat-Tat-CCR5 assay, respectively. RESULTS: CVL from all of the groups had modest antiviral activity. Anti-HIV-1 activity was decreased in CVL from postmenopausal women when compared to premenopausal women (11% vs 34%, P = .002). However, there was no difference in anti-HIV-1 activity among premenopausal women regardless of phase of menstrual cycle or contraceptive use. Anti-HIV-1 activity was associated with the protein content of the CVL (r = 0.44, P < .001). There was no difference in anti-HSV-1 or -2 activity by hormonal group. CONCLUSION: Menopause is associated with decreased innate HIV-1 activity in the lower genital tract, suggesting that factors in the vaginal fluid could play a role in increased susceptibility of HIV-1 infection in postmenopausal women. Hormonal contraceptive use, menopause, and phase of menstrual cycle did not have a measurable impact on the intrinsic anti-HSV-1 or -2 activity.

OBJECTIVE: The purpose of this study was to determine the impact of contraception, menopause, and vaginal flora on the physical and biochemical properties of cervicovaginal fluid (CVF). STUDY DESIGN: Vaginal swabs, CVF, and cervicovaginal lavage (CVL) were collected from a total of 165 healthy asymptomatic women including: postmenopausal women (n = 29), women in the proliferative (n = 26) or follicular (n = 27) phase, and women using the levonogestrel intrauterine device (n = 28), depomedroxyprogesterone acetate (n = 28) or combined oral contraceptives (n = 27). Vaginal smears were evaluated using the Nugent score. The osmolality, viscosity, density, and pH of CVL samples were measured. RESULTS: CVL from postmenopausal women and women with abnormal vaginal flora was less viscous and had higher pH than premenopausal women and women with normal flora, respectively. Women using hormonal contraceptives had more viscous CVL as compared with premenopausal women not using hormonal contraceptives, but this increase in viscosity was mitigated in the presence of bacterial vaginosis. Women using depomedroxyprogesterone acetate had less total protein in the CVL as compared with women using the levonogestrel intrauterine device, and had similar protein content when compared with postmenopausal women. CONCLUSION: The differences in CVL protein content between depomedroxyprogesterone acetate and levonogestrel intrauterine device suggest that type of progesterone and route of delivery impact the vaginal environment. Contraceptive hormone users had more viscous CVL than women not using contraceptives. However, the presence of bacterial vaginosis impacted both the pH and viscosity (regardless of hormonal contraceptive use), demonstrating that vaginal flora has a greater impact on the physical properties of CVF than reproductive hormones.

BACKGROUND: Screening for perinatal hepatitis C virus (HCV) infections remains low despite increases in the number of at-risk infants. It is unknown if pediatric screening varies by maternal HCV infection status during pregnancy. METHODS: Using a retrospective cohort of mother-infant pairs born from 2015 to 2019, we identified women with HCV and classified their infection status during pregnancy as active, probable or previous based on HCV RNA testing obtained during pregnancy. We used logistic regression to assess odds (OR) of infant screening based on maternal HCV infection status. RESULTS: Of the 503 HCV-exposed infants, 137 (27%) were born to women with previous infection, 106 (21%) to women with probable infection, and 260 (52%) to women with active infection. Completion of pediatric screening varied by maternal infection status (43% previous infection; 49% probable infection; 58% active; p=0.014). Pediatric HCV infection ranged from 1.7-7.7% by maternal VL status. Infants born to women with active infection were 2.5 times more likely (95%CI: 1.5-4.4) to have a screening test ordered versus infants of previously infected women; there was no difference for infants of women with probable infection (OR:1.6; 95%CI: 0.9-3.2). Test ordering was also associated with maternal smoking status, a visit at ≥18 months of age and outpatient documentation of HCV exposure. If a test was ordered, there was no difference in test completion by maternal infection status. However, test completion was associated with living with a non-biologic parent and earlier birth year. CONCLUSION: Infants born to women with active infection are more likely to be screened for HCV, but many children continue to be unscreened and pediatric HCV infections are going undetected. New Centers for Disease Control and Prevention pediatric HCV screening guidelines recommending earlier screening may improve screening rates.
RESUMEN
OBJECTIVE: The objective of this study was to evaluate the feasibility and acceptability of postpartum hepatitis C virus (HCV) treatment integrated within a substance use treatment program for pregnant and postpartum people with opioid use disorder (OUD). METHODS: We conducted a prospective pilot clinical trial of sofosbuvir/velpatasvir (SOF/VEL) treatment among postpartum people with OUD and HCV. Feasibility outcomes included rates of HCV treatment utilization and completion, medication adherence, and sustained virologic response 12 weeks after treatment completion (SVR12). Acceptability was measured through self-reported adverse effects and medication adherence. RESULTS: From January 2018 to August 2021, 164 pregnant people received care for OUD at the study site. Among those, 64 (39.0%) were HCV antibody positive and 45 (27.4%) had active HCV infection. Among 45 eligible patients, 32 (71.1%) enrolled and 21 (46.7%) initiated HCV treatment. Of 21 participants who initiated treatment, 16 (76.2%) completed the SOF/VEL treatment, and 11 (52.4%) completed the SVR12. All participants who completed treatment were cured. Common reasons for dropout during the HCV clinical care cascade were OUD treatment discontinuation, illicit substance use recurrence, and lost to follow-up. Participants reported high satisfaction with HCV treatment, including minimal adverse effects, and no HCV treatment concerns. CONCLUSIONS: Nearly half of pregnant people with HCV initiated postpartum treatment within an integrated care model of HCV treatment within a substance use treatment program. Postpartum SOF/VEL was efficacious, tolerable, and acceptable. Despite this, postpartum HCV treatment among people with OUD remains challenging, and many barriers remain.

BACKGROUND: Pregnancy represents a period of high HIV acquisition risk. Safety data for the monthly dapivirine vaginal ring (DVR) during pregnancy are limited. Here, we report data from the first 2 cohorts of pregnant participants in MTN-042/DELIVER, a phase 3b, randomized, open-label safety trial of DVR and oral tenofovir disoproxil fumarate/emtricitabine (TDF/FTC). MTN-042 is being conducted in 3 cohorts beginning with later gestational ages when risks of drug exposure are less. METHODS: Eligible pregnant individuals aged 18-40 years in Malawi, South Africa, Uganda, and Zimbabwe were randomized 2:1 to monthly DVR or daily TDF/FTC. Participants in cohort 1 initiated product use between 36 weeks 0 days (36 0/7 weeks) and 37 6/7 weeks gestation; participants in cohort 2 initiated product use between 30 0/7 and 35 6/7 weeks gestation. All participants continued product use until delivery or 41 6/7 weeks gestation. Pregnancy outcomes and complications were assessed and summarized using descriptive statistics and compared with local background rates obtained through a separate chart review. RESULTS: One-hundred and fifty participants were enrolled into cohort 1 with 101 randomized to DVR and 49 to TDF/FTC. One-hundred and fifty-seven participants were enrolled into cohort 2 with 106 randomized to DVR and 51 to TDF/FTC. In both cohorts, pregnancy complications were rare and similar to local background rates. CONCLUSION: In this first study of a long-acting HIV prevention agent in pregnancy, adverse pregnancy outcomes and complications were uncommon when DVR and TDF/FTC were used in the third trimester of pregnancy, suggesting a favorable safety profile for both prevention products.

With the advent of safe and well-tolerated direct-acting antiviral (DAA) medications for hepatitis C virus (HCV), disease eradication is on the horizon. However, as the rate of HCV infection among women of childbearing potential continues to rise due to the ongoing opioid epidemic in the United States, perinatal transmission of HCV presents an increasingly difficult barrier. Without the ability to treat HCV during pregnancy, complete eradication is unlikely. In this review, we discuss the current epidemiology of HCV in the United States, the current management strategy for HCV in pregnancy, as well as the potential for future use of DAAs in pregnancy.

OBJECTIVES: To evaluate efficacy and satisfaction of dextromethorphan as a non-narcotic adjuvant to current analgesic regimens for medication abortion. STUDY DESIGN: We conducted a randomized, double-blinded, placebo-controlled trial. We randomized eligible participants (N = 156) 1:1 to adjunctively take dextromethorphan (loading dose 60 mg and two subsequent 30 mg doses at 2 and 5 hours after misoprostol administration) or placebo combined with usual-care nonsteroidal anti-inflammatory medications ± opioids for pain. Participants reported pain scores and satisfaction using a secure texting application at 2, 5, 8, and 24 hours after misoprostol administration. Our primary outcome was worst pain score and total analgesic use. RESULTS: Baseline demographics of enrolled participants were similar between randomization arms. Worst pain scores for participants receiving dextromethorphan versus placebo (8.0 vs 7.0, p = 0.06) did not differ. Total milligram usage of ibuprofen (800 mg vs 610 mg, p =.62), acetaminophen (1000 mg vs 1300 mg, p = 0.62), and opioids (10 mg vs 15 mg, p = 0.51) did not differ between the randomization groups. Participants randomized to placebo were significantly more likely to be satisfied with their pain control (91% vs 75%, p = 0.02). CONCLUSION: Dextromethorphan used adjunctively with standard analgesics did not reduce pain associated with medication abortion. Participants who received dextromethorphan reported decreased satisfaction with their pain control. IMPLICATIONS: Dextromethorphan used adjunctively with commonly used analgesic regimens did not reduce medication abortion associated pain. Many participants did not use analgesics as counseled, and nearly 25% used no analgesia during medication abortion.

OBJECTIVE: We evaluated the pharmacokinetics of double-dose levonorgestrel (LNG) implants to overcome the drug-drug interaction with efavirenz-based antiretroviral therapy (ART). STUDY DESIGN: We conducted a nonrandomized, open-label, parallel-group, longitudinal pharmacokinetic study among Ugandan women ages 18-45 years. Participants with HIV on ART containing efavirenz 600 mg received 300 mg of LNG implants (Jadelle®, Bayer, New Zealand): 300LNG+ART group. We compared our outcomes with women without HIV using standard dose, 150 mg of LNG implants: 150LNG group. The implant was placed on day zero in both groups, and we quantified plasma LNG concentrations over 48 weeks post implant insertion. LNG pharmacokinetic parameters were estimated using noncompartmental techniques. Our primary outcome was the geometric mean ratio with 90% confidence intervals of LNG area under the concentration-time curve over 24 weeks (AUC0-24w) between groups. Demographic data were described as median (interquartile range). A secondary outcome compared between-group percent of LNG concentrations ≥300 pg/mL, a minimum threshold selected a priori based on observed pregnancies in Ugandan women on standard-dose LNG implants plus efavirenz. RESULTS: We enrolled 27 women in the 300LNG+ART group (34 [28.0 to 40.5] years and 61.0 [49.8-66.0] kg) and 19 women in the 150LNG group (33 [30.0 to 34.5] years and 64.9 [59.0 to 74.5] kg). LNG AUC0-24w was 34% lower for 300LNG+ART versus 150LNG (geometric mean 9998 vs. 15,231 pg*week/mL, respectively [geometric mean ratio 0.66 (90% confidence intervals, 0.54 to 0.80)]). The percentage of participants with LNG concentrations ≥300 pg/mL was not statistically different between groups at week 24 (300LNG+ART: 74.1%; 150LNG: 89.5%; p = 0.27). CONCLUSION: Double-dose LNG implant did not completely overcome the drug-drug interaction with efavirenz. IMPLICATION: In women using ART containing efavirenz, placing two implant systems (300 mg) did not normalize LNG pharmacokinetics compared with the standard-dose implant (150 mg), and some women had evidence of ovulatory activity. Alternative ART without drug-drug interactions, such as dolutegravir, is recommended with contraceptive implants.

OBJECTIVE: Describe the experiences and perspectives among pregnant people with chronic HCV infection receiving ledipasvir/sofosbuvir (LDV/SOF) therapy during pregnancy. METHODS: We conducted semi-structured, in-depth interviews within an open-label, phase 1 study of LDV/SOF therapy among pregnant people with chronic HCV infection. Participants took 12 weeks of LDV/SOF and were interviewed at enrollment and again at the end of treatment. We transcribed the interviews verbatim and coded them with NVivo software for subsequent inductive thematic analysis. RESULTS: Nine pregnant people completed the study, leading to 18 interview transcripts. All participants identified as women. Eight women acquired HCV through injection drug use, and 1 through perinatal transmission. We identified 3 themes. (1) Treatment for HCV during pregnancy with LDV/SOF was tolerable and convenient. (2) Women described that taking investigational LDV/SOF increased their self-esteem and sense of well-being due to possible cure from HCV, and they felt that the experience of working hard to achieve cure may potentially prevent return to drug abuse in the future. (3) Women appreciated researchers and providers that gave non-judgmental care and communicated honestly, and preferred person-centered care that acknowledges women's individual needs. CONCLUSIONS: Women stated that cure from HCV would be "life-changing," and described antepartum treatment for HCV with LDV/SOF as tolerable and desired, when provided by non-judgmental providers. Antepartum treatment was found to be acceptable by study participants and should be further evaluated to combat the increasing HCV epidemic among young persons, including pregnant people.
RESUMEN
OBJECTIVE: To investigate the frequency and outcome of high-risk human papillomavirus (HPV) DNA testing of atypical squamous cell of unknown significance (ASC-US) and low-grade squamous intraepithelial lesion (LSIL) vaginal ThinPrep Pap tests (TPPTs). METHODS: Atypical squamous cell of unknown significance and LSIL vaginal TPPTs (from women without a cervix) from 2005 to 2008 were identified retrospectively. The frequency of HPV testing in response to these cytologic abnormalities and results of testing were determined and compared with cervical TPPTs. The frequency and results of subsequent vaginal biopsies were reviewed. RESULTS: Of the ASC-US vaginal TPPTs, 76.5% (270/353) underwent HPV testing, with 31.9% (86/270) positive. Atypical squamous cell of unknown significance cervical TPPTs underwent HPV testing less often (69.5%, 7,155/10,297) but were more commonly HPV-positive (49.7%, 3,558/7,155). Similarly, the majority of LSIL vaginal TPPTs (59.2%, 202/341) underwent HPV testing, with 66% (133/202) testing positive. This compares with only 11.0% (1,092/9,947) of cervical LSIL TPPTs undergoing HPV testing, with 73.2% (799/1,092) positive. The increased rates of HPV test performance and lower rates of HPV positivity in vaginal ASC-US and LSIL TPPTs compared with similarly abnormal cervical TPPTs were statistically significant (p <.05) by χ analysis. Histologic evaluation was more common after HPV-positive ASC-US or LSIL vaginal TPPTs compared with HPV-negative results. Most high-grade vaginal neoplasias were diagnosed subsequent to a positive HPV result. CONCLUSIONS: Human papillomavirus testing of ASC-US and LSIL vaginal TPPTs is common; lower rates of HPV positivity were found in vaginal versus cervical ASC-US and LSIL TPPTs. The majority of high-grade vaginal neoplasias were diagnosed subsequent to positive HPV testing. Evidence-based guidelines for the use of HPV testing for the management of vaginal cytologic abnormalities are needed.

BACKGROUND: Hepatitis C virus (HCV) infection is increasing among pregnant women because of the opioid epidemic, yet there are no interventions to reduce perinatal HCV transmission or to treat HCV during pregnancy. Physiological changes in pregnancy alter the pharmacokinetics of some medications; thus, our aim was to compare the pharmacokinetic parameters of ledipasvir 90 mg plus sofosbuvir 400 mg during pregnancy with non-pregnant women. METHODS: This was an open-label, phase 1 study of pregnant women with genotype 1 HCV infection and their infants. A reference group of women who had participated in pharmacokinetic studies of ledipasvir-sofosbuvir during phase 2 and 3 trials was used. Participants were enrolled at Magee-Womens Hospital (Pittsburgh, PA, USA) between 23 and 24 weeks' gestation and had a 12-week course of oral ledipasvir-sofosbuvir (daily 90 mg ledipasvir plus 400 mg sofosbuvir). Three 12-h intensive pharmacokinetic visits were done at 25-26, 29-30, and 33-34 weeks' gestation and individual pharmacokinetics were summarised by geometric mean across the three visits. The primary outcome, analysed in all participants without suspected dosing errors, was the ledipasvir-sofosbuvir area under the concentration-time curve of the dosing interval (AUCtau) during pregnancy compared with the reference group by geometric mean ratio. This study is registered with ClinicalTrials.gov, NCT02683005. FINDINGS: From Oct 1, 2016, to Sept 30, 2018, 29 pregnant women were screened and nine (31%) were enrolled. Eight (89%) women were included in the primary analysis. Ledipasvir and sofosbuvir exposures were similar in the pregnant women versus the non-pregnant reference group (geometric mean ratio of AUCtau ledipasvir 89·3% [90% CI 68·7-116·1]; sofosbuvir 91·1% [78·0-106·3]). INTERPRETATION: Ledipasvir-sofosbuvir was safe and effective without clinically meaningful differences in drug exposure among pregnant versus non-pregnant women.

PURPOSE OF REVIEW: The purpose of this review is to discuss the reasons for HCV testing during pregnancy and to review what is known about antiviral treatment during pregnancy. RECENT FINDINGS: Hepatitis C virus affects over 3 million persons in the United States and is one of the leading infectious causes of death. While HCV is most commonly transmitted via parenteral exposures, thus affecting people who inject drugs, it is also transmitted from mother-to-child. Due to an expanding opioid crisis, an increasing number of women of childbearing age are now infected, resulting in transmission to infants. Risk-based screening has never been proven effective and thus universal screening of pregnant women for HCV infection has been recommended. SUMMARY: Obstetricians may play a key role in the U.S. by implementing universal testing for HCV in pregnant women, thereby enhancing the health of mothers and identifying children at risk.
