RESUMEN

BACKGROUND: In North American countries, national guidelines have strongly recommended formula over breastmilk for people with human immunodeficiency virus (HIV) because of concern for HIV transmission. However, data from resource-limited settings suggest the risk is <1% among virally suppressed people. Information regarding breastfeeding experience in high-resource settings is lacking. METHODS: A retrospective multisite study was performed for individuals with HIV who breastfed during 2014-2022 in the United States (8 sites) and Canada (3 sites). Descriptive statistics were used for data analysis. RESULTS: Among the 72 cases reported, most had been diagnosed with HIV and were on antiretroviral therapy prior to the index pregnancy and had undetectable viral loads at delivery. Most commonly reported reasons for choosing to breastfeed were health benefits, community expectations, and parent-child bonding. Median duration of breastfeeding was 24 weeks (range, 1 day to 72 weeks). Regimens for infant prophylaxis and protocols for testing of infants and birthing parents varied widely among institutions. No neonatal transmissions occurred among the 94% of infants for whom results were available ≥6 weeks after weaning. CONCLUSIONS: This study describes the largest cohort to date of people with HIV who breastfed in North America. Findings demonstrate high variability among institutions in policies, infant prophylaxis, and infant and parental testing practices. The study describes challenges in weighing the potential risks of transmission with personal and community factors. Finally, this study highlights the relatively small numbers of patients with HIV who chose to breastfeed at any 1 location, and the need for further multisite studies to identify best care practices.

RESUMEN

Persons with HIV can receive mixed messages about the safety of breastfeeding. We sought to assess if they felt coerced to formula feed when counseled about practices to reduce HIV transmission. Persons with HIV who had given birth were eligible to complete a survey to describe their experiences with infant feeding counseling and if they felt coerced to formula feed. An Iowa Infant Feeding Attitude Scale (IIFAS) assessed attitudes towards breastfeeding. Qualitative analyses were performed on narrative responses. One hundred surveys were collected from sites in Georgia, North Carolina, Pennsylvania, and South Carolina. The mean IIFAS score (n, 85) was 47 (SD 9.2), suggesting relatively favorable attitudes toward breastfeeding. Thirteen persons reported feeling coerced to formula feed. When controlling for choosing to give any breast milk, persons with any college education were more likely to report feeling coerced (aOR 9.8 [95% CI 1.8-52.5]). Qualitative analyses revealed three themes: perceiving breastfeeding as unsafe, engaging in shared decision-making, and resisting advice to formula feed. Persons with HIV desire to be counseled about safe infant feeding practices and have their questions answered without judgement. We highlight experiences of persons with HIV that reflect a need for a nuanced approach to infant feeding counseling.

RESUMEN

OBJECTIVE: To evaluate the associations of HIV infection with preterm birth (PTB), and of HIV antiretroviral therapy (ART) with PTB. METHODS: We analysed singleton live-born pregnancies among women from 1995 to 2019 in the Women's Interagency HIV Study, a prospective cohort of US women with, or at risk for, HIV. The primary exposures were HIV status and ART use before delivery [none, monotherapy or dual therapy, or highly active antiretroviral therapy (HAART)]. The primary outcome was PTB < 34 weeks, and, secondarily, < 28 and < 37 weeks. We analysed self-reported birth data, and separately modelled the associations between HIV and PTB, and between ART and PTB, among women with HIV. We used modified Poisson regression, and adjusted for age, race, parity, tobacco use and delivery year, and, when modelling the impact of ART, duration from HIV diagnosis to delivery, nadir CD4 count, and pre-pregnancy viral load and CD4 count. RESULTS: We analysed 488 singleton deliveries (56% exposed to HIV) to 383 women. The risk of PTB < 34 weeks was similar among women with and without HIV, but the risk of PTB < 37 weeks was higher [32% vs. 23%; adjusted risk ratio (aRR) = 1.43; 95% confidence interval (CI): 1.07-1.91] among women with HIV. The risk of PTB < 34 weeks was lower among women with HIV receiving HAART than among those receiving no ART (7% vs. 26%; aRR:0.19; 95% CI: 0.08-0.44). The associations between HAART and PTB < 28 and < 37 weeks were similar. CONCLUSIONS: Antiretroviral therapy exposure was associated with a decreased risk of PTB among a US cohort of women with HIV. Given the growing concerns about ART and adverse pregnancy outcomes, this finding that ART may be protective for PTB is reassuring.

RESUMEN

BACKGROUND: Primary human papillomavirus (HPV) screening (PHS) utilizes oncogenic human papillomavirus (oncHPV) testing as the initial cervical cancer screening method and typically, if positive, additional reflex-triage (eg, HPV16/18-genotyping, Pap testing). While US guidelines support PHS usage in the general population, PHS has been little studied in women living with HIV (WLWH). METHODS: We enrolled n = 865 WLWH (323 from the Women's Interagency HIV Study [WIHS] and 542 from WIHS-affiliated colposcopy clinics). All participants underwent Pap and oncHPV testing, including HPV16/18-genotyping. WIHS WLWH who tested oncHPV[+] or had cytologic atypical squamous cells of undetermined significance or worse (ASC-US+) underwent colposcopy, as did a random 21% of WLWH who were oncHPV[-]/Pap[-] (controls). Most participants additionally underwent p16/Ki-67 immunocytochemistry. RESULTS: Mean age was 46 years, median CD4 was 592 cells/µL, 95% used antiretroviral therapy. Seventy WLWH had histologically-determined cervical intraepithelial neoplasia grade 2 or greater (CIN-2+), of which 33 were defined as precancer (ie, [i] CIN-3+ or [ii] CIN-2 if concurrent with cytologic high grade squamous intraepithelial lesions [HSILs]). PHS had 87% sensitivity (Se) for precancer, 9% positive predictive value (PPV), and a 35% colposcopy referral rate (Colpo). "PHS with reflex HPV16/18-genotyping and Pap testing" had 84% Se, 16% PPV, 30% Colpo. PHS with only HPV16/18-genotyping had 24% Colpo. "Concurrent oncHPV and Pap Testing" (Co-Testing) had 91% Se, 12% PPV, 40% Colpo. p16/Ki-67 immunochemistry had the highest PPV, 20%, but 13% specimen inadequacy. CONCLUSIONS: PHS with reflex HPV16/18-genotyping had fewer unnecessary colposcopies and (if confirmed) could be a potential alternative to Co-Testing in WLWH.

RESUMEN

BACKGROUND: Current US cervical cancer screening guidelines recommend screening cessation at the age of 65 years provided women have adequate previous screening and no history of precancer. Women living with HIV are at higher risk of cervical cancer than women living without HIV. Furthermore, limited data exists to quantify the risk of cervical cancer among women who otherwise would qualify for screening cessation. OBJECTIVE: This study aimed to determine whether guidelines recommending women to discontinue cervical cancer screening at the age of 65 years are appropriate for women living with HIV. STUDY DESIGN: Semiannual Papanicolaou testing was performed as part of surveillance visits in the Women's Interagency HIV Study. Launched in October 1994, the Women's Interagency HIV Study is a federally funded US multisite cohort study that has enrolled 3678 women living with HIV and 1304 women living without HIV; we included data throughout September 2019 onward. Conventional Papanicolaou tests were collected at scheduled 6-month visits and read centrally according to the 1991 Bethesda System criteria. Results were analyzed among women at least 65 years of age. The primary endpoint was high-grade cytology, including high-grade squamous intraepithelial lesions; atypical glandular cells; atypical squamous cells, cannot exclude high-grade lesions; and malignant cytology. Wilcoxon rank-sum tests were used to compare the continuous variables, and Chi-square tests or the Fisher exact tests were used to compare the categorical variables. The Kaplan-Meier method was used to calculate the cumulative incidence. Poisson regression was used to compare 2 incidence rates. RESULTS: Of 169 eligible women (121 women living with HIV and 48 women living without HIV) who contributed 678.4 person-years of observation after reaching the age of 65 years, 2.2% had high-grade cytologic abnormalities. However, no cancer was found. Furthermore, 20 women had previous precancer results, and 74 women had abnormal Papanicolaou test results in the previous decade. Among 50 women (38 women living with HIV and 12 women living without HIV) with a previous hysterectomy and no history of cervical precancer, the cumulative incidence rates of high-grade squamous intraepithelial lesions were 0.6 (95% confidence interval, 0.0-3.2) per 100 person-years for women living with HIV and 0.0 (95% confidence interval, 0.0-8.1) per 100 person-years for women living without HIV (P=.61). Only 48 women (27 women living with HIV and 21 women living without HIV) had cervices and met the current guidelines to discontinue screening; their risk of experiencing high-grade squamous intraepithelial lesions was 2.2 (95% confidence interval, 0.6-5.5) per 100 person-years overall and did not vary by HIV status (2.3 [95% confidence interval, 0.5-6.8] per 100 person-years for women living with HIV and 1.8 [95% confidence interval, 0.0-9.8] per 100 person-years for women living without HIV; P=.81). CONCLUSION: Most women living with HIV do not meet the criteria for cervical cancer screening cessation and will need to continue screening over the age of 65 years; however, women who meet the criteria for screening cessation have risks of high-grade squamous lesions similar to women living without HIV and may choose to discontinue.

RESUMEN

To explore the associations of urbanicity with clinical/behavioral outcomes and sociodemographic factors among women living with HIV in the Southern United States, 523 participants of the Women's Interagency HIV Study were classified into population density quartiles. Rural-Urban Commuting Area codes revealed that 7% resided in areas where >30% commute to urban areas, 2% resided in small towns or rural areas, and 91% resided in varying densities of urban areas. Although women in lower density, mostly suburban areas reported higher socioeconomic indicators such as advanced education and greater annual household income, larger proportions of women in the lowest density quartile perceived discrimination in health care settings and agreed with several internalized HIV stigma scale items. Women in the lower quartiles had higher CD4 counts, while those in the lowest quartile were more likely to have a suppressed HIV viral load, report being employed, and not report a history of drug use or current heavy alcohol use. More research is needed to understand the interplay between population density and mechanisms contributing to HIV control as well as increased internalized stigma and perceived discrimination, along with how to target interventions to improve outcomes for individuals with HIV across urban, suburban, and rural areas.

RESUMEN

Infection by human papillomavirus (HPV) type 16, the most oncogenic HPV type, was found to be the least affected by HIV-status and CD4 count of any of the approximately 13 oncogenic HPV types. This relative independence from host immune status has been interpreted as evidence that HPV16 may have an innate ability to avoid the effects of immunosurveillance. However, the impact of immune status on other individual HPV types has not been carefully assessed. We studied type-specific HPV infection in a cohort of 2,470 HIV-positive (HIV[+]) and 895 HIV-negative (HIV[-]) women. Semi-annually collected cervicovaginal lavages were tested for >40 HPV types. HPV type-specific prevalence ratios (PRs), incidence and clearance hazard ratios (HRs), were calculated by contrasting HPV types detected in HIV[+] women with CD4 < 200 to HIV[-] women. HPV71 and HPV16 prevalence had the weakest associations with HIV-status/CD4 count of any HPV, according to PRs. No correlations between PRs and HPV phylogeny or oncogenicity were observed. Instead, higher HPV type-specific prevalence in HIV[-] women correlated with lower PRs (ρ = -0.59; p = 0.0001). An alternative (quadratic model) statistical approach (PHIV+ = a*PHIV- + b*PHIV- 2 ; R2 = 0.894) found similar associations (p = 0.0005). In summary, the most prevalent HPV types in HIV[-] women were the types most independent from host immune status. These results suggest that common HPV types in HIV[-] women may have a greater ability to avoid immune surveillance than other types, which may help explain why they are common.

RESUMEN

The objective was to assess the diagnostic test accuracy of high-risk human papillomavirus (hrHPV) testing of self-collected urine and cervicovaginal samples for the detection of cervical intraepithelial neoplasia grade 2 or higher (CIN2+). We recruited a convenience sample of women 25 to 65 years of age who were undergoing clinically indicated colposcopy at two medical centers in North Carolina between November 2016 and January 2019. Women with normal cytology results and positive hrHPV results were also recruited. Urine samples, self-collected cervicovaginal samples, provider-collected cervical samples, and cervical biopsy samples were obtained from all enrolled women. Samples were tested for hrHPV DNA using the Onclarity assay (Becton Dickinson, Sparks, MD). Biopsy samples were histologically graded as CIN2+ or

RESUMEN

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.

RESUMEN

OBJECTIVE: Cervical excision procedures are essential to the care of cervical dysplasia and malignancy. We sought to determine whether learner involvement in cervical excision procedures affects the quality of excision specimen. MATERIALS AND METHODS: A retrospective cohort study of cervical cancer patients diagnosed from July 1, 2000, to July 1, 2015, was performed. We included patients who had (1) a cervical excision procedure, either loop electrosurgical excision procedure or cold knife cone, and (2) pathologic information available. Primary outcome was the margin status of the specimen; secondary outcome was the size of the excision specimen including both width and depth. The exposure of interest was trainee participation, defined as resident physicians under the supervision of either a gynecologist or gynecologic oncologist. Descriptive statistics and general linear models were used for analysis. RESULTS: Ninety-four patients were identified. Overall, 58% (n = 54) of procedures were performed with trainee involvement. There was no difference in age, body mass index, or specimen width between trainee-performed and nontrainee-performed excisions. There was no significant difference in the status of margins with or without a trainee [44/57 (77%) and 29/37 (78%), respectively, p = .89]. There was a statistically significant difference in median specimen depth between trainee-performed and nontrainee-performed cases (15.4 mm vs 12 mm, p < .02). When adjusting for age, body mass index, excision type, indication, presence of trainee, and type of supervising physician, only the indication and type of excision were associated with greater depth of excision, (p < .01). CONCLUSIONS: Trainee involvement in cervical excision procedures does not alter the quality of excision specimen.

RESUMEN

OBJECTIVES: Self-collection of samples for human papillomavirus (HPV) testing (self-collection) has the potential to increase cervical cancer screening among underscreened women. We assessed attitudes toward at-home HPV self-collection compared with clinic-based Pap testing in this higher-risk population. MATERIALS AND METHODS: Participants were low-income women in North Carolina overdue for cervical cancer screening. Women self-collected samples at home, returned samples by mail for HPV testing, and completed phone questionnaires about at-home HPV self-collection. Participants were referred to clinic-based Pap testing and invited to complete a second questionnaire about Pap testing. A cross-sectional questionnaire compared attitudes, experiences, and preferences for self-collection versus Pap testing and assessed predictors of preference for HPV self-collection. RESULTS: Half (51%) of 221 women reported a preference for HPV self-collection, 19% preferred Pap testing, and 27% reported no preference. More women reported difficulty finding time to do the Pap test (31%) than the self-test (13%, p = .003) and being afraid of the self-test results (50%) than the Pap test results (36%, p = .02). There were relatively fewer reports of physical discomfort and pain from self-collection than Pap testing (discomfort: 18% self; 48% Pap; pain: 8% self; 30% Pap, p = .001). No differences were found in positive versus negative thoughts about the tests, trust in the tests' safety and accuracy, or willingness to do tests again. CONCLUSIONS: Overall positive attitudes toward HPV self-collection compared with Pap testing among underscreened women suggest that self-collection is a promising option to increase cervical cancer screening in this high-risk population.

RESUMEN

BACKGROUND: Little is known about fertility choices and pregnancy outcome rates among HIV-infected women in the current combination antiretroviral treatment era. OBJECTIVE: We sought to describe trends and factors associated with live-birth and abortion rates among HIV-positive and high-risk HIV-negative women enrolled in the Women's Interagency HIV Study in the United States. STUDY DESIGN: We analyzed longitudinal data collected from Oct. 1, 1994, through Sept. 30, 2012, through the Women's Interagency HIV Study. Age-adjusted rates per 100 person-years live births and induced abortions were calculated by HIV serostatus over 4 time periods. Poisson mixed effects models containing variables associated with live births and abortions in bivariable analyses (P < .05) generated adjusted incidence rate ratios and 95% confidence intervals. RESULTS: There were 1356 pregnancies among 2414 women. Among HIV-positive women, age-adjusted rates of live birth increased from 1994 through 1997 to 2006 through 2012 (2.85-7.27/100 person-years, P trend < .0001). Age-adjusted rates of abortion in HIV-positive women remained stable over these time periods (4.03-4.29/100 person-years, P trend = .09). Significantly lower live-birth rates occurred among HIV-positive compared to HIV-negative women in 1994 through 1997 and 1997 through 2001, however rates were similar during 2002 through 2005 and 2006 through 2012. Higher CD4+ T cells/mm3 (≥350 adjusted incidence rate ratio, 1.39 [95% CI 1.03-1.89] vs <350) were significantly associated with increased live-birth rates, while combination antiretroviral treatment use (adjusted incidence rate ratio, 1.35 [95% CI 0.99-1.83]) was marginally associated with increased live-birth rates. Younger age, having a prior abortion, condom use, and increased parity were associated with increased abortion rates among both HIV-positive and HIV-negative women. CD4+ T-cell count, combination antiretroviral treatment use, and viral load were not associated with abortion rates. CONCLUSION: Unlike earlier periods (pre-2001) when live-birth rates were lower among HIV-positive women, rates are now similar to HIV-negative women, potentially due to improved health status and combination antiretroviral treatment. Abortion rates remain unchanged, illuminating a need to improve contraceptive services.

RESUMEN

BACKGROUND: Minimizing time to HIV viral suppression is critical in pregnancy. Integrase strand transfer inhibitors (INSTIs), like raltegravir, are known to rapidly suppress plasma HIV RNA in nonpregnant adults. There are limited data in pregnant women. OBJECTIVE: We describe time to clinically relevant reduction in HIV RNA in pregnant women using INSTI-containing and non-INSTI-containing antiretroviral therapy (ART) options. STUDY DESIGN: We conducted a retrospective cohort study of pregnant HIV-infected women in the United States from 2009 through 2015. We included women who initiated ART, intensified their regimen, or switched to a new regimen due to detectable viremia (HIV RNA >40 copies/mL) at ≥20 weeks gestation. Among women with a baseline HIV RNA permitting 1-log reduction, we estimated time to 1-log RNA reduction using the Kaplan-Meier estimator comparing women starting/adding an INSTI in their regimen vs other ART. To compare groups with similar follow-up time, we also conducted a subgroup analysis limited to women with ≤14 days between baseline and follow-up RNA data. RESULTS: This study describes 101 HIV-infected pregnant women from 11 US clinics. In all, 75% (76/101) of women were not taking ART at baseline; 24 were taking non-INSTI containing ART, and 1 received zidovudine monotherapy. In all, 39% (39/101) of women started an INSTI-containing regimen or added an INSTI to their ART regimen. Among 90 women with a baseline HIV RNA permitting 1-log reduction, the median time to 1-log RNA reduction was 8 days (interquartile range [IQR], 7-14) in the INSTI group vs 35 days (IQR, 20-53) in the non-INSTI ART group (P < .01). In a subgroup of 39 women with first and last RNA measurements ≤14 days apart, median time to 1-log reduction was 7 days (IQR, 6-10) in the INSTI group vs 11 days (IQR, 10-14) in the non-INSTI group (P < .01). CONCLUSION: ART that includes INSTIs appears to induce more rapid viral suppression than other ART regimens in pregnancy. Inclusion of an INSTI may play a role in optimal reduction of HIV RNA for HIV-infected pregnant women presenting late to care or failing initial therapy. Larger studies are urgently needed to assess the safety and effectiveness of this approach.

RESUMEN

BACKGROUND: Determining cervical precancer risk among human immunodeficiency virus (HIV)-infected women who despite a normal Pap test are positive for oncogenic human papillomavirus (oncHPV) types is important for setting screening practices. METHODS: A total of 2791 HIV-infected and 975 HIV-uninfected women in the Women's Interagency HIV Study were followed semiannually with Pap tests and colposcopy. Cumulative risks of cervical intraepithelial neoplasia grade 2 or greater (CIN-2+; threshold used for CIN treatment) and grade 3 or greater (CIN-3+; threshold to set screening practices) were measured in HIV-infected and HIV-uninfected women with normal Pap tests, stratified by baseline HPV results, and also in HIV-infected women with a low-grade squamous intraepithelial lesion (LSIL; benchmark indication for colposcopy). RESULTS: At baseline, 1021 HIV-infected and 518 HIV-uninfected women had normal Pap tests, of whom 154 (15%) and 27 (5%), respectively, tested oncHPV positive. The 5-year CIN-2+ cumulative risk in the HIV-infected oncHPV-positive women was 22% (95% confidence interval [CI], 9%-34%), 12% (95% CI, 0%-22%), and 14% (95% CI, 2%-25%) among those with CD4 counts <350, 350-499, and ≥500 cells/µL, respectively, whereas it was 10% (95% CI, 0%-21%) in those without HIV. For CIN-3+, the cumulative risk averaged 4% (95% CI, 1%-8%) in HIV-infected oncHPV-positive women, and 10% (95% CI, 0%-23%) among those positive for HPV type 16. In HIV-infected women with LSIL, CIN-3+ risk was 7% (95% CI, 3%-11%). In multivariate analysis, HIV-infected HPV16-positive women had 13-fold (P = .001) greater CIN-3+ risk than oncHPV-negative women (referent), and HIV-infected women with LSIL had 9-fold (P < .0001) greater risk. CONCLUSIONS: HIV-infected women with a normal Pap result who test HPV16 positive have high precancer risk (similar to those with LSIL), possibly warranting immediate colposcopy. Repeat screening in 1 year may be appropriate if non-16 oncHPV is detected.

RESUMEN

OBJECTIVE: To describe a cohort of women receiving care after abnormal Pap smears and to assess predictors of follow-up in a cohort of women with cervical intraepithelial neoplasia (CIN) 2-3. STUDY DESIGN: This was a retrospective cohort study of women attending a colposcopy clinic in 2011. Data was collected by chart review and a bivariate analysis was performed to identify predictors of follow-up. RESULTS: In 2011, 21% (156/745) of women attending a colposcopy clinic at a tertiary medical center were diagnosed with CIN 2-3. Of those women 79% returned to the clinic for their recommended follow-up procedures within 8 months. Of the following factors-severity of diagnosis, age, race/ethnicity, health insurance status, language, distance to clinic, and tobacco/contraception! condom use-only young age (< 29 years) was associated with late or lack of follow-up in bivariate analysis (odds ratio 2.67, 95% confidence interval 1.10-6.83). When women under age 21 were excluded, this association was no longer observed (OR 2.31, 95% CI 0.92-6.06). CONCLUSION: In this cohort of mostly uninsured women, overall follow-up for a CIN 2-3 diagnosis was high. No single factor predictive for follow-up was identified in appropriately screened women.

RESUMEN

OBJECTIVE: The objective of the study was to evaluate the efficacy of intravaginal application of 5% 5-fluorouracil (5-FU) for the treatment of cervical intraepithelial neoplasia (CIN) 2 in women. STUDY DESIGN: Women aged 18-29 years with CIN 2 were recruited for this randomized controlled trial of observation vs treatment with intravaginal 5-FU. Women in the observation group returned in 6 months for a Papanicolaou smear, colposcopy, and a human papillomavirus (HPV) deoxyribonucleic acid test. Women in the 5-FU group were treated with intravaginal 5-FU once every 2 weeks for a total of 16 weeks and were similarly evaluated at 6 months. All women who had a baseline visit were included in the intention-to-treat analysis. Values of P < .05 were considered statistically significant. RESULTS: Between August 2010 and June 2013, 60 women were randomized and had a baseline visit for intervention (n = 31) vs observation (n = 29). Of women who had cervical biopsy results at 6 months, regression of disease was demonstrated in 93% of women in the 5-FU group (26 of 28) and 56% of women in the observation group (15 of 27). Under the intention-to-treat analysis, a relative risk for cervical disease regression of 1.62 (95% confidence interval [CI], 1.10-2.56) was found between the 5-FU and observation arms (P = .01). When the cervical biopsy, Papanicolaou smear, and HPV results were combined for the 6 month follow-up visit, 50% of the 5-FU group (14 of 28) had a documented normal biopsy, normal Papanicolaou smear, and negative HPV test compared with 22% in the observation group (6 of 27) (relative risk, 2.25; 95% confidence interval, 1.05-5.09; P < .05). There were no moderate or severe side effects in the intervention group. CONCLUSION: Topical 5-FU appears to be an effective medical therapy for CIN 2 in young women. 5-FU is readily available and may be considered as an off-label treatment option for young women with CIN 2 who are interested in the treatment of disease but want to avoid excisional procedures.

RESUMEN

BACKGROUND: Preterm delivery is a major cause of neonatal morbidity and mortality. Human papillomavirus (HPV) infection is common in reproductive-aged women. We hypothesised that abnormal cervical cancer screening tests, as a proxy for HPV infection, would be associated with preterm delivery. METHODS: We conducted a retrospective cohort study of women delivering liveborn singletons beyond 20 weeks gestation, who had a Papanicolaou (Pap) test within 1 year prior to delivery. Women with abnormal Pap or positive high-risk HPV tests, classified as having 'abnormal screening', were compared with women classified as having 'normal screening' in bivariate analysis for overall preterm delivery at less than 37 weeks gestation. Using Poisson regression, we report unadjusted (RR) and adjusted (aRR) risk ratios for spontaneous preterm delivery due to preterm labour and preterm premature rupture of membranes. RESULTS: Among 2686 women meeting criteria for analysis, 213 (8%) had abnormal screening. Women with abnormal screening, compared with normal screening, were not more likely to deliver preterm (12.2% vs. 9.8%, RR 1.3 [95% confidence interval (CI) 0.9, 1.8], aRR 1.2 [95% CI 0.8, 1.7]). Women with abnormal screening, however, were at greater risk for spontaneous preterm delivery in unadjusted and adjusted analysis (8.9% vs. 4.5%; RR 2.0 [95% CI 1.2, 3.2], aRR 1.8 [95% CI 1.1, 2.9]). CONCLUSIONS: There was no difference in risk of overall preterm delivery in women with abnormal compared with normal cervical cancer screening tests. Our data suggest, however, that abnormal screening in pregnancy may be associated with spontaneous preterm delivery.

RESUMEN

OBJECTIVE: Recommendations regarding treatment of cervical intraepithelial neoplasia (CIN) 2 in women have evolved over the years: young women with CIN 2 may be offered observation with Pap smears and colposcopy every 6 months instead of immediate excision or ablation of disease. The purpose of this study was to observe patient follow-up during the initiation of this management protocol for young women with CIN 2. MATERIALS AND METHODS: This was a retrospective review of clinical outcomes of women younger than 30 years with CIN 2 on index biopsy and planned follow-up at UNC between July 2009 and August 2010. A chart review for clinical variables, follow-up visits, and progression of disease was conducted. Primary analysis determined the rate of follow-up and pathology at 6 months. Secondary analysis investigated risk factors for incomplete follow-up. RESULTS: Seventy women met inclusion criteria; 46 were managed with observation. Twenty-eight (60.8%; 28/46) women completed a follow-up visit. Demographic and clinical variables did not reach statistical significance in predicting the likelihood of completion of a follow-up visit, although there was a trend toward greater follow-up in employed patients (odds ratio = 5.25, 95% confidence interval = 0.84-34.78). Approximately half (52.4%; 11/21) of women with a completed cervical biopsy demonstrated regression of disease during the study period. CONCLUSIONS: On the basis of these data, follow-up in this population was unpredictable based on basic demographic or clinical factors that we often use to judge likelihood of compliance with medical recommendations. The percentage of patients with regression at follow-up was as expected from the natural history of CIN 2.

RESUMEN

Background: Cervical cancer disproportionately affects women in low- and middle-income countries (LMICs), which bear 90% of deaths. Current precancer treatments rely on healthcare workers who may be out of reach for many women. Development of a patient-controlled cervical precancer treatment can significantly improve access in remote areas and promote secondary prevention of cervical cancer. Methods: This is a phase I trial among 18 HIV-positive and HIV-negative women in Kenya, investigating use of artesunate vaginal pessaries as treatment for cervical precancer among women screening positive for cervical precancer who need excisional treatment. The primary objective will be the safety of self-administered artesunate pessaries. Participants will self-administer 200mg of artesunate vaginally daily for 5 days, followed by a drug-free week, repeated for a total of 4 cycles (artesunate self-administration on weeks 1, 3, 5, 7). The total study duration, including participant follow-up is 48 weeks. Safety and adherence will be assessed through review of symptom diaries and biweekly follow-ups during the treatment phase. Data analysis will include quantitative and qualitative methods. Figure 1 illustrates the study schema. Discussion: Considering the challenges associated with excisional treatments for cervical precancer in LMICs where access to care is limited, this study proposes an alternative approach using intravaginal Artesunate. This clinical trial will provide important safety and efficacy data on using artesunate as a topical therapy for both HIV-positive and HIV-negative women. Trial Registration: ClinicalTrials.gov identifier: NCT06165614.

RESUMEN

Background: Cervical cancer continues to be a major health issue in low- and middle-income countries (LMICs). Despite increasing access to screening, access to precancer treatment remains a significant challenge in LMICs, highlighting a need for innovative, accessible and resource-appropriate treatment approaches, including self-administered therapies. Methods: A cross-sectional mixed-methods study was conducted among men aged 25-65 with a current female partner in Kisumu County, Kenya. Participants were sequentially recruited and surveyed to evaluate their understanding of human papillomavirus and cervical cancer, their views on screening and treatment and their attitudes toward self-administered therapies. Focus group discussions (FGDs) with a subset of the survey participants further explored their treatment preferences and perceptions. Results: Two hundred fourteen men participated in the survey, and 39 men participated in FGDs. The median age was 39 years, and 51% had a primary school education or less. Most (96%) were in a committed relationship, and 74% earned $10 or less daily. There was strong support for self-administered topical therapies, with 98% willing to support their partners using such treatments if available. Additionally, most participants were open to supporting necessary abstinence or condom use, though 76% believed their partners might hesitate to request condom use. When given an option, most preferred their partner to self-administer such therapies at home compared to provider administration at a health facility, citing convenience, cost-effectiveness and privacy. Preferences varied between two potential therapies, 5-Fluorouracil and Artesunate, based on their administration frequency, duration and abstinence requirements. Qualitative findings largely supported the quantitative analysis. Conclusion: The study demonstrates strong support for self-administered topical therapies for cervical precancer among Kenyan men. Additional research on acceptability, feasibility and efficacy in different LMICs could pave the way for these therapies to help bridge current cervical precancer treatment gaps in these settings.
