RESUMO

Awareness of HIV status in Malawi is 88.3% and lowest among 15-24-year-olds (76.2%). There is a need to understand HIV testing history and transmission in this age group. We analyzed pooled HIV surveillance data to describe testing history and HIV recent infection among 8,389 HIV-positive 15-24-year-olds from 251 sites in Malawi between 2019 and 2022. Most HIV-positive 15-24-year-olds were female; aged 23-24 years; rural residents; and diagnosed at voluntary counseling and testing. No prior HIV testing was reported in 43.5% and 32.9% of 15-19-year-olds and males, respectively. Overall, 4.9% of HIV-positive diagnoses were classified as recent HIV infections, with the highest proportions among breastfeeding women (8.2%); persons tested at sexually transmitted infection clinics (9.0%); persons with a prior negative test within 6 months (13.0%); and 17-18-year-olds (7.3%). Tailored and innovative HIV prevention and testing strategies for young adolescents, young males, and pregnant and breastfeeding women are needed for HIV epidemic control.

RESUMO

INTRODUCTION: Accessible planning tools tailored for low-and middle-income countries can assist decision makers in comparing implementation of different cervical cancer screening approaches and treatment delivery scenarios in settings with high cervical cancer burden. METHODS: The Cervical Precancer Planning Tool (CPPT) was developed by PATH for users to explore and compare the accuracy of screening approaches, what treatment equipment to procure, and how best to deploy treatment equipment in a given country. The CPPT compares four screening approaches: 1) visual inspection with acetic acid (VIA), 2) HPV testing, 3) HPV testing followed by a VIA triage, and 4) HPV testing followed by an enhanced triage test. Accuracy of screening outcomes (e.g., true positives, false positives) is based on published sensitivity and specificity of tests to detect cervical precancerous lesions. The CPPT compares five scenarios for deploying ablative treatment equipment: 1) cervical precancer equipment at every location a woman is screened (single visit approach), 2) equipment only at a hospital level, 3) a single unit of equipment in each district, 4) allowing two districts to share a single unit of equipment, and 5) equipment placed at select district hospitals paired with mobile outreach. Users can customize the CPPT by adjusting pre-populated baseline values and assumptions, including population estimates, screening age range, screening frequency, HPV and HIV prevalence, supply costs, and health facility details. RESULTS: The CPPT generates data tables and graphs that compare the results of implementing each of the four screening and five treatment scenarios disaggregated by HIV status. Outputs include the number and outcomes of women screened, cost of each screening approach, provider time and cost saved by implementing self-sampling for HPV testing, number of women treated, treatment equipment needed by type, and the financial and economic costs for each equipment deployment scenario. CONCLUSION: The CPPT provides practical information and data to compare tradeoffs of patient access and screening accuracy as well as efficient utilization of equipment, skilled personnel, and financial resources. Country decision makers can use outputs from the CPPT to guide the scale-up of cervical cancer screening and treatment while optimizing limited resources.

RESUMO

BACKGROUND: Cervical cancer is a significant public health problem, with 570,000 new cases and 300,000 deaths of women per year globally, mostly in low- and middle-income countries. In 2018 the WHO Director General made a call to action for the elimination of cervical cancer as a public health problem. MAIN BODY: New thinking on programmatic approaches to introduce emerging technologies and screening and treatment interventions of cervical precancer at scale is needed to achieve elimination goals. Implementation research (IR) is an important yet underused tool for facilitating scale-up of evidence-based screening and treatment interventions, as most research has focused on developing and evaluating new interventions. It is time for countries to define their specific IR needs to understand acceptability, feasibility, and cost-effectiveness of interventions as to design and ensure effective implementation, scale-up, and sustainability of evidence-based screening and treatment interventions. WHO convened an expert advisory group to identify priority IR questions for HPV-based screening and treatment interventions in population-based programmes. Several international organizations are supporting large scale introduction of screen-and-treat approaches in many countries, providing ideal platforms to evaluate different approaches and strategies in diverse national contexts. CONCLUSION: For reducing cervical cancer incidence and mortality, the readiness of health systems, the reach and effectiveness of new technologies and algorithms for increasing screening and treatment coverage, and the factors that support sustainability of these programmes need to be better understood. Answering these key IR questions could provide actionable guidance for countries seeking to implement the WHO Global Strategy towards cervical cancer elimination.

RESUMO

Abstract Objective: To evaluate age patterns in human papillomavirus (HPV) prevalence and visual inspection with acetic acid (VIA) positivity among women participating in cervical cancer screening in Honduras. Materials and methods: Data on the HPV status (careHPV) and subsequent VIA in HPV-positive women were retrieved from three provinces within the Public Health Sector. Results: Between 2015 and 2018, 60 883 women aged 15-85 years were screened. HPV was detected in 15%, with variation by age, peaking at 20-24 years (27.8%) decreasing to 16% at 30-49 years. Differences in point age-specific HPV prevalence were observed between provinces, but with similar age pattern. VIA was positive in 24.5% of the women aged 30-44 years. Conclusions: The age pattern of the HPV prevalence supports starting HPV testing at age 30+. The low positivity of VIA in ages close to menopause suggest underdetection of cervical lesions in this age group.


Resumen Objetivo: Evaluar la prevalencia del virus del papiloma humano (VPH) y la positividad a la inspección visual con ácido acético (IVA) de cáncer cervicouterico, según edad en mujeres tamizadas en Honduras. Material y métodos: Se extrajo información sobre la prueba de VPH (careHPV) y de IVA en tres provincias en el ámbito de la Atención Pública en Salud. Resultados: Durante 2015-2018, 60 883 mujeres de 15-85 años fueron tamizadas, 15% fueron VPH positivas con valores máximos en mujeres de 20-24 años (27.8%), con una disminución a 16% entre 30-49 años. Se observaron diferencias mínimas entre provincias, con un patrón de edad similar. La IVA fue positiva en 24.5% en mujeres de 30-44 años, con una posterior disminución. Conclusiones: La curva de prevalencia del VPH respalda el tamizar con VPH a los 30+ años. La baja positividad de la IVA en edades cercanas a la menopausia sugiere una subdetección de lesiones cervicales en este grupo.

RESUMO

Scaling up coverage of routine cervical screening in low-resource settings must be accompanied by efforts to retain women throughout the screening cascade and continuum of care, including adequate follow-up of abnormal results. The Scale-Up Project implemented human papillomavirus (HPV) testing for cervical cancer screening within public-sector health facilities in Honduras between 2015 and 2019. Women who were HPV-positive but did not have visually confirmed cervical lesions upon visual inspection with acetic acid (VIA-negative) were instructed to return to the health center after 1 year for repeat HPV testing. The current evaluation assessed the effectiveness of recall strategies to prompt women to return for retesting. Clinic staff placed reminder phone calls and followed up with short message service (SMS) or home visits, if needed. We summarized number of contacts, type of contacts, and time elapsed until return to the clinic, and used log-binomial regression to identify factors associated with return to the clinic. We identified 558 women who were initially HPV-positive VIA-negative from 8 clinics as needing repeat HPV testing 1 year later. Mean age was 43.2 years. Nearly all women (98.6%) were successfully contacted and 75.1% completed repeat HPV testing. The majority of contacts (65.4%) were phone calls, and nearly half of women who returned to the clinic (42.9%) did so after 1 contact. Mean days between contact and presentation at the clinic was 10.7 (standard deviation: 14.7). Women who required 3 or more contacts were 21% less likely to return for repeat HPV testing (prevalence ratio: 0.79; 95% confidence interval=0.69,0.90; P<.001) as compared to women who received only 1 contact. Reminder phone calls were highly successful at recalling women for HPV retesting in Honduras. This low-touch intervention should be included as part of standard follow-up to retain women throughout the continuum of cervical cancer screening and treatment.

RESUMO

BACKGROUND: In Nicaragua, cervical cancer is the leading cause of cancer death among women. Human papillomavirus (HPV) testing, primarily using self-sampling, was introduced between 2014 and 2018 in three provinces. We analyzed data from the HPV screening program with the goal of describing key characteristics including reach, HPV prevalence, triage and treatment, and factors associated with follow-up completion. METHODS: We analyzed individual-level data from routinely collected forms for women attending HPV-based cervical cancer screening. HPV-positive women were triaged with Pap or visual inspection with acetic acid (VIA) prior to treatment. Logistic regression was used to identify factors associated with receiving triage and treatment; analyses were adjusted for province, age, and self- vs. provider-collected sampling. RESULTS: Forty-four thousand six hundred thirty-five women were screened with HPV testing; 96.6% of women used self-sampling. Six thousand seven hundred seventy-six women were HPV positive (15.2%), 54.0% of screen-positive women received triage, and 53.1% of triage-positive women were treated, primarily with cryotherapy. If women lost at triage are included, the overall treatment percentage was 27.8%. Province and provider sampling were significantly associated with completing triage. Province and triage type were significantly associated with receiving treatment. The odds of receiving treatment after Pap triage as compared to VIA was significantly lower (aOR: 0.05, 95% CI: 0.04-0.08, p < 0.001), and the relative proportion of women receiving treatment after Pap triage versus VIA was 0.29. CONCLUSIONS: Introduction of HPV testing resulted in a substantial number of women screened, and acceptance of self-sampling was high. Management of screen-positive women remained a challenge, particularly with Pap triage. Our results can inform other developing countries as they work to reach World Health Organization (WHO) elimination targets.

RESUMO

The Scale-Up project introduced vaginal self-sampling and low-cost human papillomavirus (HPV) testing as the primary approach for cervical cancer screening in selected public health centers in Guatemala, Honduras, and Nicaragua. We evaluate the country-specific accomplishments in screening: target-coverage, triage, and treatment. Between 2015 and 2018, cervical cancer screening was offered to women at least 30 years of age. Triage of HPV-positive women was based on visual inspection with acetic acid or Pap. Aggregated data included total women screened, use of self-sampling, age, time elapsed since last screening, HPV results, triage tests, triage results, and treatment. A total of 231,741 women were screened for HPV, representing 85.8% of the target populations within the project. HPV positivity was lower in Guatemala (12.4%) compared to Honduras and Nicaragua (14.5% and 14.2%, respectively, p < 0.05). A follow-up triage test was completed for 84.2%, 85.8%, and 50.1% of HPV-positive women in Guatemala, Nicaragua, and Honduras, respectively. Of those with a positive triage test, 84.7%, 67.1%, and 58.8% were treated in Guatemala, Nicaragua, and Honduras, respectively. First-time screening was highest in Nicaragua (55.8%) where self-sampling was also widely used (97.1%). The Scale-Up project demonstrated that large-scale cervical cancer screening and treatment intervention in a high-burden, low-resource setting can be achieved. Self-sampling and ablative treatment were key to the project's achievements. Data monitoring, loss to follow-up, and triage methods of screen- positive women remain critical to full success.

RESUMO

INTRODUCTION: High maternal HIV incidence contributes substantially to mother-to-child HIV transmission (MTCT) in some settings. Since 2006, HIV retesting during the third trimester and breastfeeding has been recommended by the World Health Organization in higher prevalence (≥5%) settings to reduce MTCT. However, many countries lack clarity on when and how often to retest pregnant and postpartum women to optimize resources and service delivery. We reviewed and characterized national guidelines on maternal retesting based on timing and frequency. METHODS: We identified 52 countries to represent variations in HIV prevalence, geography, and MTCT priority and searched available national MTCT, HIV testing and HIV treatment policies published between 2007 and 2017 for recommendations on retesting during pregnancy, labour/delivery and postpartum. Recommended retesting frequency and timing was extracted. Country HIV prevalence was classified as: very low (<1%), low (1% to 5%), intermediate (>5 to <15%) and high (≥15%). Women with unknown HIV status at delivery/postpartum were included in retesting guidelines. RESULTS AND DISCUSSION: Overall, policies from 49 countries were identified; 51% from 2015 or later and most (n = 25) were from Africa. Four countries were high HIV prevalence, seven intermediate, sixteen low and twenty-two very low. Most (n = 31) had guidance on universal voluntary opt-out HIV testing at the first antenatal care (ANC) visit. Beyond the first ANC visit, the majority (78%, n = 38) had guidance on retesting; 22 recommended retesting all women with unknown/negative status, five only if unknown HIV status, three in pregnancy based on risk and eight combining these approaches. Retesting was universally recommended during pregnancy, labour/delivery, and postpartum for all high prevalence settings and four of seven intermediate prevalence settings. Five UNAIDS priority countries for EMTCT with low/very low HIV prevalence, but high/intermediate MTCT, had no guidance on retesting. CONCLUSIONS: Retesting guidelines for pregnant and postpartum women were ubiquitous in high prevalence countries and defined in some intermediate prevalence countries, but absent in some low HIV prevalence countries with high MTCT. Countries may require additional guidance on how to optimize maternal HIV testing and whether to prioritize retesting efforts or discontinue universal retesting based on HIV incidence. Research is needed to assess country-level guideline implementation and impact.

RESUMO

Background: Understanding the absolute and relative risk of human immunodeficiency virus type 1 (HIV) acquisition during pregnancy and the postpartum period can inform HIV prevention strategies for women. Methods: We used a complementary log-log model and data from 2751 HIV-serodiscordant couples to compare the probability of HIV acquisition among women per sex act during early pregnancy, late pregnancy, the postpartum period, and the nonpregnant period. Results: At total of 686 pregnancies were identified, and 82 incident HIV infections occurred. After adjustment for condom use, age, preexposure prophylaxis (PrEP) use, and HIV viral load, the per-act probability of HIV acquisition was higher in late pregnancy (adjusted relative risk [aRR], 2.82; P = .01) and the postpartum period (aRR, 3.97; P = .01) as compared to that during nonpregnant period. For a 25-year-old woman not taking PrEP, the HIV acquisition probability per condomless sex act with an HIV-infected male partner with a viral load of 10 000 copies/mL was 0.0011 (95% confidence interval [CI] 0.005-0.0019), 0.0022 (95% CI, 0.0004-0.0093), 0.0030 (95% CI, 0.0007-0.0108), and 0.0042 (95% CI, 0.0007-0.0177) during the nonpregnant period, early pregnancy, late pregnancy, and the postpartum period, respectively. Conclusion: The HIV acquisition probability per condomless sex act steadily increased during pregnancy and was highest during the postpartum period, suggesting that biological changes during pregnancy and the postpartum period increase HIV susceptibility among women.

RESUMO

Within the first year of implementation, 43% of women who tested HIV positive at their first antenatal care visit were no longer retained and being followed in the free prevention of mother to child transmission (PMTCT) of HIV program offered by the Kenyan Ministry of Health and Médecins Sans Frontières in the informal settlement of Kibera, Nairobi. This study aimed to explore barriers to enrolling and remaining engaged in PMTCT services throughout the pregnancy and postpartum periods. Qualitative data from 31 focus group discussions and 35 in-depth interviews across six stakeholder groups that included women, men, and PMTCT service providers were analyzed. Using an inductive exploratory approach, four researchers coded the data and identified key themes. Five themes emerged from the data that may influence attrition from PMTCT service in this setting: 1) HIV in the context of Kibera, 2) knowledge of HIV status, 3) knowledge of PMTCT, 4) disclosure of HIV status, and 5) male partner support for PMTCT services. A new HIV diagnosis during pregnancy immediately triggered an ongoing risk assessment of perceived hazards in the home, community, and clinic environments that could occur as a result of female participation in PMTCT services. Male partners were a major influence in this risk assessment, but were generally unaware of PMTCT services. To preserve relationships with male partners, meet community expectations of womanhood, and maintain confidentiality while following recommendations of healthcare providers, women had to continuously weigh the risks and benefits of PMTCT services and interventions. Community-based HIV testing and PMTCT education, male involvement in antenatal care, and counseling customized to assist each woman in her own unique risk assessment, may improve uptake of and retention in care and optimize the HIV prevention benefit of PMTCT interventions.

RESUMO

Understanding fertility desires and preferences for HIV prevention among individuals living with HIV, including the potential use of pre-exposure prophylaxis (PrEP) by HIV uninfected partners, can inform the delivery of safer conception counseling to reduce the risk of HIV transmission during pregnancy attempts. Men and women, predominantly heterosexual, engaged in HIV care in Seattle, WA, self-administered a questionnaire and we abstracted antiretroviral therapy (ART) status and HIV viral levels from medical records. We summarized participants' sexual behavior, fertility desires, and preferences for safer conception strategies and used log-binomial regression to identify demographic, sexual, and behavioral factors associated with perceived acceptability of PrEP for HIV uninfected partners during pregnancy attempts. 52% of the 150 participants were female and the mean age was 48 years (range 23-74). 94.7% of participants were using ART and 79.3% had HIV viral load < 40 copies/mL. 22.2% of men and 34.6% of women reported that a healthcare provider had initiated discussion about fertility desires. 28.7% of participants were reproductive-age and desired children. Among sexually active reproductive-age participants with fertility desires, 56.3% reported inconsistent condom use and 62.5% did not report using effective birth control. 74.4% of reproductive age participants with fertility desires perceived that PrEP would be acceptable to an HIV uninfected partner and there were no significant predictors of PrEP acceptability. Nearly one third of reproductive-aged individuals living with HIV expressed fertility desires, highlighting a need for safer conception counseling in this setting. PrEP and ART were favored safer conception strategies.

RESUMO

INTRODUCTION: HIV testing is key to the delivery of pre-exposure prophylaxis (PrEP): testing HIV-uninfected at-risk persons is the first step for PrEP initiation and ongoing HIV testing is an essential part of PrEP delivery. Thus, novel and cost-effective HIV-testing approaches to streamline delivery of PrEP are urgently needed. Within a demonstration project of PrEP for HIV prevention among high-risk HIV serodiscordant couples in Kenya (the Partners Demonstration Project), we conducted a pilot evaluation of HIV self-testing. METHODS: Clinic visits were scheduled quarterly and included in-clinic HIV testing using fingerstick rapid HIV tests and refills of PrEP prescriptions. HIV oral fluid self-test kits were provided for participants to use in the two-month interval between scheduled quarterly clinic visits. Acceptability of HIV self-testing was assessed using both quantitative and qualitative methods. RESULTS: We found that 222 of 226 (98%) HIV-uninfected persons who were offered accepted self-testing. Nearly all (96.8%) reported that using the self-testing kit was easy. More than half (54.5%) reportedly did not share the HIV results from self-testing with anyone and almost all (98.7%) the participants did not share the HIV self-testing kits with anyone. Many participants reported that HIV self-testing was empowering and reduced anxiety associated with waiting between clinic HIV tests. CONCLUSION: HIV self-testing was highly acceptable and may therefore be a feasible strategy to efficiently permit routine HIV testing between PrEP refills.

RESUMO

Sharing of pre-exposure prophylaxis (PrEP) medications is a concern for PrEP implementation. For HIV-1 serodiscordant couples, sharing may undermine the HIV-1 prevention benefit and also cause antiretroviral resistance if taken by HIV-1 infected partners. Within a PrEP efficacy trial among HIV-1 serodiscordant couples, we assessed the occurrence of PrEP sharing by self-report and plasma tenofovir concentrations in HIV-1 infected partners. PrEP sharing was self-reported at <0.01% of visits, and 0%-1.6% of randomly selected and 0% of purposively selected specimens from HIV-1 infected participants had detectable tenofovir concentrations (median: 66.5 ng/mL, range: 1.3-292 ng/mL). PrEP sharing within HIV-1 serodiscordant couples was extremely rare.

RESUMO

PURPOSE OF REVIEW: Despite tremendous promise as a female-controlled HIV prevention strategy, implementation of preexposure prophylaxis (PrEP) among women has been limited, in part because of disparate efficacy results from randomized trials in this population. This review synthesizes existing evidence regarding PrEP efficacy for preventing HIV infection in women and considerations for delivering PrEP to women. RECENT FINDINGS: In three efficacy trials, conducted among men and women, tenofovir-based oral PrEP reduced HIV acquisition in subgroups of women by 49-79% in intent-to-treat analyses, and by >85% when accounting for PrEP adherence. Two trials did not demonstrate an HIV prevention benefit from PrEP in women, but substantial evidence indicates those results were compromised by very low adherence to the study medication. Qualitative research has identified risk perception, stigma, and aspects of clinical trial participation as influencing adherence to study medication. Pharmacokinetic studies provide supporting evidence that PrEP offers HIV protection in women who are adherent to the medication. SUMMARY: Tenofovir-based daily oral PrEP prevents HIV acquisition in women. Offering PrEP as an HIV prevention option for women at high risk of HIV acquisition is a public health imperative and opportunities to evaluate implementation strategies for PrEP for women are needed.

RESUMO

Retention of patients in long term care and adherence to treatment regimens are a constant challenge for HIV, prevention of mother to child transmission of HIV (PMTCT), and TB programmes in sub-Saharan Africa. This study describes the implementation and outcomes of an active defaulter tracing system used to reduce loss to follow-up (LTFU) among HIV, PMTCT, TB, and HIV/TB co-infected patients receiving treatment at three Médecins Sans Frontières clinics in the informal settlement of Kibera, Nairobi, Kenya. Patients are routinely contacted by a social worker via telephone, in-person visit, or both very soon after they miss an appointment. Patient outcomes identified through 1066 tracing activities conducted between 1 April 2008 and 31 March 2009 included: 59.4% returned to the clinic, 9.0% unable to return to clinic, 6.3% died, 4.7% refused to return to clinic, 4.5% went to a different clinic, and 0.8% were hospitalized. Fifteen percent of patients identified for tracing could not be contacted. LTFU among all HIV patients decreased from 21.2% in 2006 to 11.5% in 2009. An active defaulter tracing system is feasible in a resource poor setting, solicits feedback from patients, retains a mobile population of patients in care, and reduces LTFU among HIV, PMTCT, and TB patients.
