Daily ritonavir-boosted darunavir for viral suppression in pregnancy (DRV-P).

BACKGROUND: Ritonavir-boosted darunavir (DRV/r) is a preferred protease inhibitor in pregnant women living with HIV. Current practice at British Columbia's referral centre (the Oak Tree Clinic) is to dose DRV/r as 800/100 mg daily throughout pregnancy, although some guidelines recommend DRV/r 600/100 mg twice daily due to altered pharmacokinetics with once-daily dosing. OBJECTIVES: We describe the effect of once-daily DRV/r on viral suppression, vertical transmission, adverse drug effects and adherence in pregnant women living with HIV. METHODS: This was a retrospective analysis of pregnant women living with HIV in British Columbia. Eligible women gave birth between January 2015 and August 2021, and took DRV/r 800/100 mg daily at any time during pregnancy. RESULTS: Thirty-four women were included in this study. The mean (SD) age was 33 (5) years. Thirty (88%) women were diagnosed with HIV prior to pregnancy, with 22 (73%) having viral suppression at baseline. Four (12%) were diagnosed in pregnancy, with a median baseline viral load of 9616 copies/mL (range 8370-165 000). Viral suppression was achieved by 16 (100%), 24 (75%) and 26 (74%) women in the first, second and third trimesters, respectively. No vertical transmission occurred. This combination was well tolerated, with adverse drug effects that did not result in discontinuation or change in therapy. Most women maintained >75% adherence to once-daily DRV/r at all times during pregnancy. CONCLUSIONS: Ritonavir-boosted darunavir 800/100 mg daily appears to be an appropriate dosing strategy for pregnant women living with HIV who are able to maintain optimal adherence.

Variations in CD4 counts during pregnancy in women living with HIV.

OBJECTIVE: Our objective was to determine the frequency at which CD4 counts drop below 200 cells/mm3 during pregnancy in women living with HIV and to identify factors associated with this. METHODS: Data from 2005 to 2020 from two prospective Canadian cohorts of pregnant women living with HIV were extracted. As per national guidelines, women received antiretroviral therapy and CD4 counts were monitored once per trimester and at delivery. RESULTS: Among 775 included cases, 72 (9.3%) had CD4 counts <200 cells/mm3 at the first pregnancy visit. Of the 703 remaining pregnancies with CD4 counts ≥200 cells/mm3 at the initial visit, 20 (2.8%) were associated with a drop to <200 cells/mm3 . In univariate analysis, factors associated with this drop were coinfection with hepatitis B virus or hepatitis C virus (odds ratio [OR] 4.0, 95% confidence interval [CI] 1.52-10.50), lower first visit CD4 counts (OR 0.165, 95% CI 0.08-0.34), and baseline haemoglobin levels <11 g/dL (OR 2.89, 95% CI 1.04-8.00). In multivariable analysis, only CD4 count at first visit remained independently associated with this drop. A cut-off CD4 count ≤450 cells/mm3 at the first pregnancy visit had a sensitivity of 100% to detect cases of CD4 drop to <200 cells/mm3 . CONCLUSION: A drop of CD4 count to <200 cells/mm3 is uncommon during pregnancy in women living with HIV. Our results suggest that CD4 monitoring only once in pregnancy would be safe in women whose CD4 count is >450 cells/mm3 at the first pregnancy visit.

Factors associated with HIV viral load control in the early postpartum period - a Canadian prospective cohort study.

Despite success in managing HIV during pregnancy, challenges remain around sustained adherence with antiretroviral therapy (ART), and the suboptimal viral load (VL) suppression during the postpartum period. The objective of this study was to compare VL levels at delivery and during the postpartum period and assess factors associated with lack of viral suppression during the postpartum period in Canada. We combined data from two Canadian prospective cohorts, which included 286 HIV-positive women (352 pregnancies) who delivered between 2012 and 2020. Delivery VL, postpartum VL, and potential factors associated with an undetectable VL (<50 copies/mL), 2-18 weeks after delivery were assessed. To account for the correlation between multiple pregnancies from the same woman, generalized estimating equations were used to assess bivariate associations. Ninety-nine per cent of pregnant women were on ART during pregnancy compared to 93% during the postpartum period. Of those with available VL results (n = 214 pregnancies), 94% of women achieved an undetectable VL at delivery compared to 87% during the postpartum period. The postpartum period is a challenging time for ART use and VL control. Qualitative studies are needed to better understand these challenges and guide us in designing adequate interventions.

Guideline No. 450: Care of Pregnant Women Living with HIV and Interventions to Reduce Perinatal Transmission.

OBJECTIVE: This guideline provides an update on the care of pregnant women living with HIV and the prevention of perinatal HIV transmission. This guideline is a revision of the previous guideline, No. 310 Guidelines for the Care of Pregnant Women Living With HIV and Interventions to Reduce Perinatal Transmission, and includes an updated review of the literature with contemporary recommendations. TARGET POPULATION: Pregnant women newly diagnosed with HIV during antenatal screening and women living with HIV who become pregnant. This guideline does not include specific guidance for girls/women of reproductive age living with HIV who are not pregnant. OUTCOMES: Prevention of perinatal HIV transmission is a key indicator of the success of a health care system and requires multidisciplinary care of pregnant women living with HIV. Intended outcomes include guidance on best practice in perinatal management for Canadian health care providers for pregnant women living with HIV; reduction of perinatal transmission of HIV toward a target of eradication of perinatal transmission; provision of optimal antenatal care for pregnant women to ensure the best maternal health outcomes and HIV suppression; and evidence-based support and recommendations for pregnant women living with HIV, maintaining awareness and consideration of the complex psychosocial impacts of living with HIV. BENEFITS, HARMS, AND COSTS: The perinatal transmission of HIV has significant morbidity and mortality implications for the child, with associated lifelong health care costs. Pregnancy presents an emotionally and physically vulnerable time for pregnant women as well as an opportunity to engage them in health promotion. This guidance does not include recommendations with additional costs to health care facilities compared with the previous guideline. Application of the recommendations is aimed at health benefits to both mother and child by optimizing maternal health and preventing perinatal HIV transmission. EVIDENCE: Published and unpublished literature was reviewed with a focus on publications post-2013. OVID-Medline, Embase, PubMed and the Cochrane Library databases were searched for relevant publications available in English or French for each section of this guideline. Results included systematic reviews, randomized controlled trials, and observational studies published from 2012 to 2022. Searches were updated on a regular basis and incorporated in the guideline until May 2023. Unpublished literature, protocols, and international guidelines were identified by accessing the websites of health-related agencies, clinical practice guideline collections, and national and international medical specialty societies. VALIDATION METHODS: The authors rated the quality of evidence and strength of recommendations using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. See Appendix A (Tables A1 for definitions and A2 for interpretations of strong and conditional recommendations). INTENDED AUDIENCE: The intended users of this guideline include obstetric care providers and infectious disease clinicians who provide care for pregnant women living with HIV. SOCIAL MEDIA SUMMARY: Updated Canadian HIV in pregnancy guideline informed by global research and tailored to Canadian healthcare needs and goals for pregnant women living with HIV and their families. SUMMARY STATEMENTS: RECOMMENDATIONS.

Prescribing patterns of antiretroviral treatments during pregnancy for women living with HIV in Canada 2004-2020: A surveillance study.

BACKGROUND: While treatment guidelines for HIV in adults have evolved rapidly with the advent of new antiretroviral (ARV) treatment, those for the prevention of vertical HIV transmission in pregnancy have evolved more slowly due to safety and efficacy concerns. Here we describe Canadian prescribing patterns for ARV treatments during pregnancy and compare them to perinatal HIV prescribing guidelines of the United States Department of Health and Human Services (HHS), that are commonly used in Canada and include recommendations for newly commercialized therapies. METHODS: The Canadian Perinatal HIV Surveillance Program (CPHSP) captures annual medical data on mothers living with HIV and their infants from 23 sites across Canada. Women from this cohort who received an ARV treatment during pregnancy and who gave birth between 2004 and 2020 were included in the study. ARV treatments were designated as 'preferred/alternative' as per HHS HIV perinatal guidelines, or 'other than preferred/alternative'. RESULTS: We identified 3673 pregnancies from 2720 women. The proportion of women that conceived while on ARV treatment increased from 29% in 2003 to 90% in 2020. Other than preferred/alternative ARV treatments were received in 1112 (30%) of pregnancies and this was significantly associated with having initiated ARV treatment before conception. CONCLUSION: In Canada during the study period, a high number of women were prescribed an other than preferred/alternative ARV treatment during pregnancy. Further optimization of ARV treatment in women of childbearing age living with HIV is warranted.

Human papillomavirus genotype concordance between Anyplex II HPV28 and linear array HPV genotyping test in anogenital samples.

Anyplex II HPV-28 (HPV-28) can detect individually 28 HPV genotypes. We assessed the agreement between linear array HPV genotyping (LA-HPV) and HPV-28 for detection of 27 HPV genotypes in 410 stored anogenital samples (75 anal samples, 335 physician-collected cervical samples) collected over 5 years from 410 individuals (13 men, 397 women), including 202 HIV-seropositive individuals. HPV DNA was detected in 393 (95.9%, 95% confidence interval [CI]: 93.4-97.4) and 382 (93.2%, 95% CI: 90.3-95.3) samples with HPV-28 and LA-HPV (p = 0.13), respectively, for a good agreement of 96.3% (κ = 0.65). Of the 10503 HPV typing results, 10195 (780 positive, 9577 negative) were concordant, for an agreement of 97.1% (95% CI: 96.7-97.4) and an excellent of κ = 0.82 (95% CI: 0.80-0.84). The mean type-specific concordance for 27 genotypes was 97.0%, 95% CI: 95.8-98.5 (κ = 0.86 ± 0.07, 95% CI: 0.83-0.88). Excellent agreement was obtained individually for all high-risk genotypes (κ = 0.81-0.97) and for most other genotypes except for types 42, 44, 54, 68, and 69. The mean number of types per sample in discordant samples detected with LA-HPV (3.0, 95% CI: 2.7-3.4) was greater than in concordant samples (1.4, 95% CI: 1.3-1.5; p< 0.001). In conclusion, HPV-28 compared favorably with LA-HPV, but was more frequently positive for HPV42 and HPV68.

Association of SARS-CoV-2 Infection During Pregnancy With Maternal and Perinatal Outcomes.

Importance: There are limited high-quality, population-level data about the effect of SARS-CoV-2 infection on pregnancy using contemporaneous comparator cohorts. Objectives: To describe maternal and perinatal outcomes associated with SARS-CoV-2 infection in pregnancy and to assess variables associated with severe disease in the pregnant population. Design, Setting, and Participants: CANCOVID-Preg is an observational surveillance program for SARS-CoV-2-affected pregnancies in Canada. This analysis presents exploratory, population-level data from 6 Canadian provinces for the period of March 1, 2020, to October 31, 2021. A total of 6012 pregnant persons with a positive SARS-CoV-2 polymerase chain reaction test result at any time in pregnancy (primarily due to symptomatic presentation) were included and compared with 2 contemporaneous groups including age-matched female individuals with SARS-CoV-2 and unaffected pregnant persons from the pandemic time period. Exposure: SARS-CoV-2 infection during pregnancy. Incident infections in pregnancy were reported to CANCOVID-Preg by participating provinces/territories. Main Outcomes and Measures: Maternal and perinatal outcomes associated with SARS-CoV-2 infection as well as risk factors for severe disease (ie, disease requiring hospitalization, admission to an intensive care unit/critical care unit, and/or oxygen therapy). Results: Among 6012 pregnant individuals with SARS-CoV-2 in Canada (median age, 31 [IQR, 28-35] years), the greatest proportion of cases were diagnosed at 28 to 37 weeks' gestation (35.7%). Non-White individuals were disproportionately represented. Being pregnant was associated with a significantly increased risk of SARS-CoV-2-related hospitalization compared with SARS-CoV-2 cases among all women aged 20 to 49 years in the general population of Canada (7.75% vs 2.93%; relative risk, 2.65 [95% CI, 2.41-2.88]) as well as an increased risk of intensive care unit/critical care unit admission (2.01% vs 0.37%; relative risk, 5.46 [95% CI, 4.50-6.53]). Increasing age, preexisting hypertension, and greater gestational age at diagnosis were significantly associated with worse maternal outcomes. The risk of preterm birth was significantly elevated among SARS-CoV-2-affected pregnancies (11.05% vs 6.76%; relative risk, 1.63 [95% CI, 1.52-1.76]), even in cases of milder disease not requiring hospitalization, compared with unaffected pregnancies during the same time period. Conclusions and Relevance: In this exploratory surveillance study conducted in Canada from March 2020 to October 2021, SARS-CoV-2 infection during pregnancy was significantly associated with increased risk of adverse maternal outcomes and preterm birth.

Elevated Blood Mitochondrial DNA in Early Life Among Uninfected Children Exposed to Human Immunodeficiency Virus and Combination Antiretroviral Therapy in utero.

BACKGROUND: Combination antiretroviral therapy (cART) during pregnancy prevents vertical transmission, but many antiretrovirals cross the placenta and several can affect mitochondria. Exposure to maternal human immunodeficiency virus (HIV) and/or cART could have long-term effects on children who are HIV exposed and uninfected (CHEU). Our objective was to compare blood mitochondrial DNA (mtDNA) content in CHEU and children who are HIV unexposed and uninfected (CHUU), at birth and in early life. METHODS: Whole-blood mtDNA content at birth and in early life (age 0-3 years) was compared cross-sectionally between CHEU and CHUU. Longitudinal changes in mtDNA content among CHEU was also evaluated. RESULTS: At birth, CHEU status and younger gestational age were associated with higher mtDNA content. These remained independently associated with mtDNA content in multivariable analyses, whether considering all infants, or only those born at term. Longitudinally, CHEU mtDNA levels remained unchanged during the first 6 months of life, and gradually declined thereafter. A separate age- and sex-matched cross-sectional analysis (in 214 CHEU and 214 CHUU) illustrates that the difference in mtDNA between the groups remains detectable throughout the first 3 years of life. CONCLUSION: The persistently elevated blood mtDNA content observed among CHEU represents a long-term effect, possibly resulting from in utero stresses related to maternal HIV and/or cART. The clinical impact of altered mtDNA levels is unclear.

Declining rates of cervical intraepithelial neoplasia in British Columbia, Canada: An ecological analysis on the effects of the school-based human papillomavirus vaccination program.

Since 2008, girls in British Columbia (BC), Canada, have been offered HPV vaccination through a school-based, publicly funded immunization program. The oldest birth cohort eligible for the vaccination program was born in 1994 and uptake is on average 63%. To evaluate the impact of the HPV vaccine in BC, ecological trends in cervical intraepithelial neoplasia (CIN) rates were assessed in young women before and after the implementation of the HPV vaccination program. Information on all Pap smears and histopathological abnormalities, in calendar years 2004-2017 in women 16-28 years of age in BC were obtained from the population-based BC Cancer Cervix Screening Program database. Rates of CIN 2 and 3 were calculated as the number of cases divided by the number of cytology specimens for that period. Rate ratios (RR) were calculated by negative binomial piecewise regression. Age-centered incidence rates of CIN 2 and 3 in BC declined significantly among women 16-23 years of age after HPV vaccine introduction compared to before vaccine introduction. The overall reduction postvaccination for CIN2 and 3 in women 16-23 years was respectively 62% (95% CI 54-68%) and 65% (95% CI 58-71%). Age-specific rates for CIN2 significantly declined for those 18-22 years of age and for those 19, 20 and 23 years of age for CIN3. Among women 24-28 years of age no decline in CIN2 and 3 rate over time was observed. The observed reduction in CIN 2 and 3 rates since the introduction of the school-based HPV vaccine program might illustrate the population impact of the BC provincial school-based HPV vaccination program.

Urinary symptoms and quality of life in women living with HIV: a cross-sectional study.

INTRODUCTION AND HYPOTHESIS: To determine prevalence and quality of life impact of lower urinary tract symptoms (LUTS) in women living with HIV (WLWH). METHODS: Cross-sectional urinary questionnaires were included in a multicenter national prospective study of the HPV vaccine in WLWH. Demographic and clinical information was abstracted from the parent study. The Urinary Distress Inventory (UDI-6) and Urinary Impact Questionnaire (UIQ-7) were administered. Wilcoxon rank sum, two-sample chi-square or Fisher's exact tests were used as appropriate to compare women with UDI-6 score ≥ 25 to those with lower UDI-6 scores on demographic and HIV-related factors. Significant categorical variables were followed up with logistic regression to estimate odds ratios (OR). RESULTS: One hundred seventy-seven women completed urinary questionnaires (85.5% of cohort). Median age was 44.1 (37.2-50.6). Mean CD4 count was 621 (410-785), and 132 women (74.6%) were virologically suppressed. Median UDI-6 score was 4.2 (0-25). Fifty-one women (28.8%) had a UIQ-7 score > 0. Among those with a UDI-6 score of at least 25, median UIQ-7 was 9.5 (0-47.6). UDI-6 ≥ 25 was significantly associated with increasing age, higher BMI, Canada as country of origin, peri-/postmenopausal status (OR 3.37, 95% CI = 1.71 to 6.75) and being parous (OR 2.92, 95% CI = 1.27 to 7.59) (all p < 0.05). HIV-related factors were not associated with UDI-6 ≥ 25. CONCLUSIONS: LUTS were common, but we did not demonstrate a negative impact on quality of life in this sample of WLWH. Large comparative studies are needed to determine whether HIV is a risk factor for bothersome LUTS in women.

Patterns of changing pregnancy intentions among women living with HIV in Canada.

BACKGROUND: Women with an undetectable viral load can become pregnant and have children with no risk of HIV transmission to their sexual partners and low risk of transmission to their infants. Contemporary pregnancy intentions of women living with HIV in Canada are poorly understood, evidenced by high rates of unintended pregnancy and low uptake of contraceptives. METHODS: We used longitudinal survey data from the Canadian HIV Women's Sexual and Reproductive Health Cohort Study (CHIWOS) to measure and compare pregnancy intentions (Yes vs No vs Unsure) at baseline, 18-months and 36-months follow-up (from 2013 to 2018) among women living with HIV of reproductive age (16-49 years) and potential. We used Sankey diagrams to depict changes in pregnancy intentions over time and multivariable logistic regression to examine the relationship between pregnancy intention within 2 years and subsequent pregnancy. RESULTS: At baseline, 41.9% (119/284) of women intended to become pregnant, 43.3% did not, and 14.8% were unsure. Across 36-months of follow-up, 41.9% (119/284) of women changed their pregnancy intentions, with 25% changing from intending to not intending to become pregnant and 13.1% vice versa. Pregnancy intentions were not strongly associated with subsequent pregnancy between baseline and 18-months (aOR 1.44; 95% CI 0.53, 3.72) or between 18 and 36-months (aOR 2.17; 95% CI 0.92, 5.13). CONCLUSIONS: Our findings underscore the need for healthcare providers to engage in ongoing discussions with women living with HIV to support their dynamic pregnancy intentions.

Immunogenicity of 2 and 3 Doses of the Quadrivalent Human Papillomavirus Vaccine up to 120 Months Postvaccination: Follow-up of a Randomized Clinical Trial.

BACKGROUND: Several countries have implemented a 2-dose (2D) human papillomavirus (HPV) vaccination schedule for adolescents based on immunobridging studies. We compared immunogenicity of 2D vs 3-dose (3D) schedules of the quadrivalent vaccine (4vHPV) up to 10 years after the first dose. METHODS: Girls aged 9-13 years were randomized to receive 2D or 3D and were compared with women aged 16-26 receiving 3D at day 1 and months 7, 24, and 120 after the first dose. Antibody levels for HPV6/11/16/18 were evaluated using the competitive Luminex immunoassay (cLIA) and total immunoglobulin G assay. Geometric mean titers (GMTs) and seropositivity rates were compared between the different groups at different time points. Noninferiority of GMT ratios was defined as the lower bound of the 2-sided 95% confidence interval (CI) being greater than 0.5. Kinetics of antibody titers over time among study groups were examined. RESULTS: At 120 months, data from 35 2D girls, 38 3D girls, and 30 3D women were used for analyses. cLIA seropositivity rates were above 95% for all HPV vaccine types and all schedules, except HPV18, with the lowest seropositivity observed among 3D women (60.0%; 95% CI, 40.6%-77.3%). GMT ratios (cLIA) for both 2D and 3D girls were noninferior to 3 doses in women for HPV6/11/16/18. Trends were comparable between assays. CONCLUSIONS: GMTs for HPV6/11/16/18 after 2D or 3D of 4vHPV in girls were noninferior to 3D in adult women up to 120 months postvaccination. This study demonstrates long-term immunogenicity of the 2D HPV vaccine schedule.

Impacts of Human Papillomavirus Immunization Programs on Rates of Anogenital Warts in British Columbia, Canada, 2000 to 2017.

BACKGROUND: In 2008, British Columbia (BC) implemented a school-based quadrivalent human papillomavirus (HPV-4) immunization program for girls born in 1994 or later. In 2015, an expanded clinic-based program included men who report sex with men (MSM) born in 1989 or later. To evaluate the impacts of HPV-4 programs on anogenital warts (AGWs), diagnosis rates were measured among women who report sex with men (WSM), men who report sex with women (MSW), and MSM. METHODS: Diagnoses of AGW were ascertained from 16 sexually transmitted infection clinics. Rates were calculated as new AGW diagnoses over person-years (py) at risk and stratified by age group, calendar period, and birth cohort. Adjusted relative rates (aRR) were estimated using multivariable Poisson regression. RESULTS: There were 204,832 clinic visits by 85,158 individuals: 28,366 (33%) WSM, 35,688 (42%) MSW, and 14,534 (17%) MSM. After adjusting for age and period, AGW rates in the 1994-1996 birth cohort decreased by 56% overall (1.21 vs. 2.72 cases/100 py; aRR, 0.44; 95% confidence interval [CI], 0.34-0.59), 65% among WSM (0.97 vs. 2.77 cases/100 py; aRR, 0.35; 95% CI, 0.22-0.57), 58% among MSW (1.60 vs. 3.78 cases/100 py; aRR, 0.42; 95% CI, 0.28-0.65), and 41% among MSM (1.14 vs. 1.19 cases/100 py; aRR, 0.59; 95% CI, 0.38-0.91) versus the 1991-1993 birth cohort. CONCLUSIONS: The HPV-4 programs had significant impacts on lowering AGW rates in BC. The greatest decrease was among WSM eligible for the school-based program, followed by birth cohorts of men who likely have sex with HPV-4 eligible women. The smallest decrease among MSM may reflect the later introduction of the clinic-based program.

Quasispecies Diversity Is a Major Risk Factor for Vertical Hepatitis C Virus Transmission.

BACKGROUND: Vertical transmission is the major cause of pediatric hepatitis C virus (HCV) infection. The objective of this study was to better understand HCV pathogenesis in pregnant women and provide insights into risk factors and mechanisms involved in vertical transmission. METHODS: Evolutionary dynamics of HCV variant spectra and HCV-specific neutralizing antibody responses were examined using high-throughput sequencing and pseudoparticle-based assays in pregnant women monoinfected with HCV (n = 17) or coinfected with HCV and human immunodeficiency virus (HIV)-1 (n = 15). RESULTS: Overall, statistically significant associations were found between HCV quasispecies diversity, selective pressure exerted on the HCV E2 envelope protein, and neutralizing activity of maternal immunoglobulins. Women with low quasispecies diversity displayed significantly higher mean aspartate aminotransferase and alanine aminotransferase levels throughout pregnancy, but this difference was restricted to monoinfected participants. Low quasispecies diversity and inefficient neutralizing activity were also significantly associated with vertical transmission, but only in the monoinfected group. CONCLUSIONS: These results indicate that maternal neutralizing antibody responses play a role in the prevention of vertical HCV transmission, but not in presence of HIV-1 coinfection, and suggest that the mechanism of vertical transmission may be different between monoinfected and coinfected women. These findings could inform management strategies for the prevention of vertical HCV transmission.

The Efficacy of the Quadrivalent Human Papillomavirus Vaccine in Girls and Women Living With Human Immunodeficiency Virus.

BACKGROUND: Human papillomavirus (HPV) vaccination is safe and efficacious in women without human immunodeficiency virus (HIV). Although good immunogenicity has been observed in women living with HIV (WLWH), efficacy data in this population are needed. METHODS: We enrolled 420 females aged ≥9 years (range, 9-65) living with HIV. Participants were to receive 3 doses of qHPV vaccine (0/2/6 months). The main endpoint was vaccine failure (ie, incident persistent qHPV infection, cervical intraepithelial neoplasia of grade 2 or higher [CIN2+], or genital warts). We compared these rates to published rates in vaccinated and unvaccinated women without HIV as well as unvaccinated WLWH. RESULTS: Among 279 eligible women, median follow-up was 2 years. In the intention-to-treat population, the incidence rate (IR) of persistent qHPV (HPV6/11/16/18) was 2.3 per 100 person-years (/100PY) (95% confidence interval [CI], 1.1-4.1), and IR of genital warts was 2.3/100PY (95% CI, 1.2-4.1). In the per-protocol efficacy population, IR of persistent qHPV was 1.0/100PY (95% CI, 0.3-2.6) and of genital warts was 1.0/100PY (95% CI, 0.3-2.5). No cases of CIN2+ occurred. Reported rates of qHPV-related infection and disease within vaccinated women without HIV, unvaccinated women without HIV, and vaccinated WLWH: 0.1 (95% CI, 0.02-0.03), 1.5 (95% CI, 1.1-2.0), and 1.2 (95% CI, 0.2-3.4) /100PY, respectively. The rate of persistent qHPV among vaccinated WLWH was lower than among unvaccinated WLWH (2.3 vs 6.0/100PY). CONCLUSIONS: Vaccinated WLWH may be at higher risk for vaccine failure than vaccinated women without HIV. However, overall rates of vaccine failure were low, and rates of persistent qHPV were lower than in unvaccinated WLWH.

Love with HIV: A Latent Class Analysis of Sexual and Intimate Relationship Experiences Among Women Living with HIV in Canada.

Love remains hidden in HIV research in favor of a focus on risk. Among 1424 women living with HIV in Canada, we explored (1) whether eight facets of sex and intimacy (marital status, sexual activity, physical intimacy, emotional closeness, power equity, sexual exclusivity, relationship duration, and couple HIV serostatus) may coalesce into distinct relationship types, and (2) how these relationship types may be linked to love as well as various social, psychological, and structural factors. Five latent classes were identified: no relationship (46.5%), relationships without sex (8.6%), and three types of sexual relationships-short term (15.4%), long term/unhappy (6.4%), and long term/happy (23.2%, characterized by equitable power, high levels of physical and emotional closeness, and mainly HIV-negative partners). While women in long-term/happy relationships were most likely to report feeling love for and wanted by someone "all of the time," love was not exclusive to sexual or romantic partners and a sizeable proportion of women reported affection across latent classes. Factors independently associated with latent class membership included age, children living at home, sexism/genderism, income, sex work, violence, trauma, depression, HIV treatment, awareness of treatment's prevention benefits, and HIV-related stigma. Findings reveal the diversity of women's experiences with respect to love, sex, and relationships and draw attention to the sociostructural factors shaping intimate partnering in the context of HIV. A nuanced focus on promoting healthy relationships and supportive social environments may offer a more comprehensive approach to supporting women's overall sexual health and well-being than programs focused solely on sexual risk reduction.

No 378 - Placentophagie.

La consommation du placenta humain a récemment été mise en évidence. Toutefois, aucune donnée probante ne fait état des bienfaits qui seraient liés à cette pratique. De plus, elle peut nuire à la santé. Par conséquent, la SOGC ne recommande pas la pratique de la placentophagie.

No. 378-Placentophagy.

Consumption of human placenta has recently been highlighted; however, there is no evidence of benefit from its consumption. In addition, there is potential for harm. Therefore the SOGC does not recommend the practice of placentophagy.

Assessing Maternity Care Providers' Knowledge of the Management of Hepatitis B in Pregnancy.

OBJECTIVE: This study sought to evaluate maternity care providers' knowledge of the management of hepatitis B virus (HBV) in pregnancy. METHODS: A total of 71 maternity care providers from obstetrics, family practice, and midwifery who were practicing at a tertiary women's hospital in Canada completed a survey assessing their demographics and knowledge of the management of HBV in pregnancy. Descriptive statistics were used to assess the survey responses. RESULTS: Of 71 participants, 28% were obstetricians, 35% were family doctors, and 37% were midwives. Most participants (72%) had seen fewer than six pregnant patients with HBV in the last 2years. Correctly, 100% of participants indicated that all pregnant patients should be screened for HBV in pregnancy, and 99% indicated that infants should receive post-exposure prophylaxis. Incorrectly, 25.4% of participants indicated that pregnancy is a contraindication to HBV immunization, 90.1% indicated the recommended timeline for infant serological follow-up, and participants were largely divided on which investigations were needed for a pregnant patient with HBV. Only 23.9% of participants indicated the current recommended viral load for consideration of antiviral treatment in pregnancy. CONCLUSION: Maternity care providers in our cohort had a strong understanding of the fundamentals of caring for pregnant patients with HBV. Continuing education should emphasize the safety of HBV vaccination in pregnancy, novel investigations in pregnancy, current evidence on the use of antivirals in pregnancy, and appropriate timelines for infant serological follow-up.

Cervical Cancer Screening in Immunocompromised Women.

In the context of changing recommendations for cervical cancer screening, differing recommendations in each province, and a lack of guidance for cervical screening of immunocompromised women, this article provides specific recommendations for cervical cancer screening of immunocompromised women in Canada.
