Self-collection based HPV testing for cervical cancer screening among women living with HIV in Uganda: a descriptive analysis of knowledge, intentions to screen and factors associated with HPV positivity

Acceptability of human papillomavirus self-sampling among women living with HIV in sub-Saharan Africa: A systematic review and meta-analysis

HPV self-sampling has the potential to improve early detection of cervical cancer among women living with HIV (WLHIV), but its acceptability varies, creating implementation challenges, especially in sub-Saharan Africa. This study aims to assess the acceptability of HPV self-sampling among WLHIV. We searched PubMed, Web of Science, CINAHL, Academic Medical Ultimate, Cochrane databases, and Google Scholar. The review protocol was registered with PROSPERO (CRD42022299781). Inclusion criteria were based on population, intervention, comparison, and outcome. Statistical analysis was done with R Studio version 4.3.2, and data abstraction was performed in Microsoft Excel. The analysis included 14 studies on the acceptability of HPV self-sampling among WLHIV. The overall acceptability rate was 73%. The pooled data showed that 94% felt comfortable with self-sampling, 72% found it easy to use, 10% reported pain, 14% felt embarrassed, and 41% felt confident about the process. The study found that a majority of WLHIV accepted HPV self-sampling, a higher rate than in the general female population. Many participants had concerns about the method's efficacy. This indicates that while WLHIV generally views self-sampling positively, additional education and support are needed to improve their confidence in its accuracy and reliability.

The impact of HPV/HIV co-infection on immunosuppression, HPV genotype, and cervical cancer biomarkers

BACKGROUND

Human papillomavirus (HPV) and human immunodeficiency virus (HIV) co-infection present a significant impact on women's health globally, especially in immunocompromised individuals. HIV-induced immunosuppression promotes the persistence of high-risk HPV infection and increased the progression to cervical cancer. The aim of this systematic review was to assessed the impact of HPV/HIV co-infection on the prevalence and distribution of HR-HPV genotypes, the level of immunosuppression and expression of cervical cancer biomarkers.

METHOD

The article selection method for this review was based on the 2020 Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standards. The total of eighty-four (84) articles from standard electronic databases mainly Web of Science, PubMed, and Scopus were extracted and reviewed. The articles were published in English between 2008 and 2024 and comprised a total of 80023 participants.

RESULTS

The HR-HPV genotypes reported across various studies include HPV16, 18, 31, 33, 35, 39, 45, 51, 52, 53, 54, 56, 58, 59, 66, 68, 70, 73, and 82. Among HIV positive individuals, the most common circulating HR-HPV genotypes were HPV16, 18, 45, 35, and 58, accounted for 11%, 10%, 9%, 8%, and 8% of cases, respectively. Approximately 29.1% and 30.0% of patients had CD4 counts of 200-400 cells/L and 300-400 cells/L, respectively. The most commonly reported cervical cancer biomarkers were p16INK4a and Ki-67, according to the analysis.

CONCLUSION

The findings indicate high prevalence of multiple HR-HPV genotypes among HIV positive individuals, indicating the impact of HPV/HIV co-infection on immunosuppression and persistence of HPV infection. The expression of cervical cancer biomarker such as p16INK4a and Ki-67 emphasized target screening and early detection strategy in high-risk population. However, there was no direct impact of HPV/HIV co-infection reported on these biomarkers and required to be studied more especially in people living with HIV.

Human papillomavirus self-sampling versus provider-sampling in low- and middle-income countries: a scoping review of accuracy, acceptability, cost, uptake, and equity

Introduction

HPV self-sampling is a relatively new, cost-effective and widely accepted method, however, uptake in LMICs remains limited. We aimed to map out the evidence and identify gaps in accuracy, acceptability, cost, equity and uptake of self-sampling vs. provider-sampling in LMICs.

Methods

We searched: MEDLINE, EMBASE, CINAHL, SCOPUS, Web of Science, and Global Index Medicus, from 1946 to July 2023. Inclusion criteria entailed studies focusing on self-sampling alone or compared to provider-sampling for HPV testing and reporting on at least one outcome of interest (accuracy, acceptability, cost, equity, or uptake). Two authors independently screened titles, abstracts, and full texts, resolving disagreements through discussion. Data was extracted by one reviewer independently, with quality checks by senior authors, and results were synthesised narratively.

Results

Our search yielded 3,739 records, with 124 studies conducted on 164,165 women aged 15-88 years between 2000 and 2023 included. Most studies were from the African region (n = 61, 49.2%). Designs included cross-sectional (n = 90, 81.1%), randomised (n = 5, 4.5%), modelling (n = 4, 3.6%), micro-costing (n = 2, 1.8%), and non-randomised crossover (n = 1, 0.9%) studies. Outcomes included; acceptability (n = 79, 63.7%), accuracy (n = 51, 41.1%), cost (n = 7, 5.6%), and uptake (n = 7, 5.6%). Most studies reported that participants preferred self-sampling, with only a few studies (n = 7, 8.9%) studies favouring provider-sampling. The sensitivity and specificity of self-sampling ranged from 37.5-96.8% and 41.6-100.0%, respectively. One study directly compared the sensitivity and specificity of dry self-collected vs. wet provider-collected sample transportation. Laboratory costs were similar, but overall costs were lower for self-sampling. Uptake was higher for self-sampling in five of the seven studies. Most studies (n = 106) mentioned equity factors like age (n = 69, 65.1%), education (n = 68, 64.2%) and place of residence (n = 59, 55.6%) but no analysis of their impact was provided.

Conclusion

HPV self-sampling is acceptable and cost-effective but, evidence of its accuracy shows varying sensitivity and specificity. Evidence on the accuracy of dry self-collected vs. wet provider-collected sample transportation is limited. Research evaluating HPV self-sampling's accuracy, including comparisons of transportation modes, uptake, the impact of equity factors in LMICs and comparisons with high-income countries is essential to inform cervical cancer screening uptake.

Experiences and perspectives regarding human papillomavirus self-sampling in sub-Saharan Africa: A systematic review of qualitative evidence

Introduction

Cervical cancer screening coverage remains low in sub-Saharan Africa (SSA) due to limited access and low uptake of available services by women. The use of HPV-based self-sampling intervention for cervical cancer screening has the potential to increase screening coverage in the region. This study aimed to analyse qualitative evidence on the experiences and perspectives of women, healthcare workers, and policymakers regarding HPV self-sampling.

Methods

We reviewed qualitative studies from January 2011 to March 2023 in PubMed, Scopus, Medline Ovid, Cochrane, and WEB of Science databases for articles with qualitative data on HPV self-sampling from different countries in SSA. The socio-ecological model was used to guide data analysis and the study findings.

Results

Thirteen qualitative studies were included for analysis, and they revealed themes under the intrapersonal, interpersonal, community, and health systems constructs of the Socio-ecological model. Intrapersonal themes included the acceptability of self-sampling, self-efficacy, and the perceived value of self-sampling. The interpersonal construct had themes such as women's spousal relationships, peer support, and the health worker's relationship with the women. The community construct had two themes: social stigma and misinformation, and the influence of cultural norms and religion. Finally, the health systems construct had themes such as the setting for self-sampling, follow-up availability of treatment services and education and awareness.

Conclusion

This study highlights the factors influencing the acceptability and uptake of an HPV-based self-sampling intervention for cervical cancer screening in SSA. Considering these findings when designing interventions in SSA is crucial to ensure acceptance and demand among end-users. Self-sampling interventions offer the potential to reach many unscreened women and increase cervical cancer screening coverage in SSA, which is an essential strategy towards achieving the World Health Organisation's cervical cancer elimination targets by the close of the century.

Prevalence of high-risk human papillomavirus genotypes in outpatient Malian women living with HIV: a pilot study

INTRODUCTION

Long-term exposure to high-risk human papillomavirus (Hr-HPV) is a well-known necessary condition for development of cervical cancer. The aim of this study is to screen for Hr-HPV using vaginal self-sampling, which is a more effective approach to improve women's adherence and increase screening rates.

METHODS

This pilot study included a total of 100 Women living with HIV (WLWHIV), recruited from the Center for Listening, Care, Animation, and Counseling of People Living with HIV in Bamako. Hr-HPV genotyping was performed on Self-collected samples using the Cepheid GeneXpert instrument.

RESULTS

The median age of WLWHIV was 44 (interquartile range [IQR], 37-50) years. Approximately 92% of the study participants preferred self-sampling at the clinic, and 90% opted to receive result notifications via mobile phone contact. The overall prevalence of Hr-HPV among study participants was 42.6%, and the most frequent Hr-HPV sub-types observed were HPV18/45 (19.1%), HPV31/35/33/52/58 (13.8%), and HPV39/68/56/66 (12.8%), followed by HPV16 (5.3%), and HPV51/59 (5.3%). WLWHIV under 35 years of age had a higher frequency of Hr-HPV compared to their older counterparts, with rates of 30% versus 11.1% (p = 0.03). The duration of antiretroviral treatment showed an inverse association with Hr-HPV negativity, with patients on treatment for 15 (IQR, 10-18) years versus 12 (IQR = 7-14) years for Hr-HPV positive patients (95% CI [1.2-5.8], t = 3.04, p = 0.003). WLWHIV with baseline CD4 T-Cell counts below 200 exhibited a higher frequency of Hr-HPV compared to those with baseline CD4 T-Cell counts above 200 (17.9% versus 1.9%, p = 0.009). However, other demographics and clinical factors, such as marital status, age of sexual debut, parity, education, history of abortion, history of preeclampsia, and cesarean delivery, did not influence the distribution of Hr-HPV genotypes.

CONCLUSION

Our findings indicate that WLWHIV under the age of 35 years old exhibited the highest prevalence of Hr-HPV infection, with HPV18/45 being the most prevalent subtype. Additionally, WLWHIV with baseline CD4 T-Cell counts below 200 showed the highest infection rates.

An intervention to increase cervical cancer screening among women living with HIV: A mixed methods study

OBJECTIVE

We examined the effectiveness of a behavioral intervention in promoting cervical cancer screening among women living with HIV (WLWH) in Ghana.

METHODS

A Mixed-methods study was conducted involving 83 WLWH, who were randomly assigned to an intervention group (n = 42) to receive voice-recorded messages based on the 3 R model (Reframing, Reprioritizing, and Reforming) or a control group (n = 41) to receive standard care. The primary outcomes were screening uptake and HPV prevalence. Other outcomes were the acceptability, appropriateness, and feasibility of the intervention.

RESULTS

The intervention group had a 100% screening rate, and the control group had a 14.63% screening rate. The prevalent rate of high-risk (hr)-HPV genotypes among the women was 67.5% (95%C.I: 0.56-0.77). Over 48% of the participants had multiple hr-HPV genotypes, 64.29% had HPV16/18/45%, and 73.21% had HPV 31/33/45/52/58. Of the women (89.30%) who screened positive, 60% of them were diagnosed and treated for pre-cancer lesions. The intervention messages were acceptable (encourage proactive behavior), feasible (simple, easy to understand), and appropriate (helpful, informative). Facilitators and barriers to self-sampling were identified.

CONCLUSION

Combining the 3 R model with self-sampling increases cervical cancer screening among WLWH.

PRACTICE IMPLICATION

Healthcare professionals and policymakers can use this model to increase cervical cancer screening.

Understanding the cervical cancer self-collection preferences of women living in urban and rural Rwanda

Cervical cancer is a leading cause of cancer among women in low- and middle-income countries. Women in Rwanda have high rates of cervical cancer due to limited access to effective screening methods. Research in other low-resource settings similar to Rwanda has shown that HPV-based self-collection is an effective cervical cancer screening method. This study aims to compare the preferences of Rwandan women in urban and rural settings toward self-collection and to report on factors related to self-collection amenability. A cross-sectional survey was conducted from June 1-9, 2022. Women were recruited from one urban and one rural clinic in Rwanda. Women were eligible for the study if they were ≥ 18 years and spoke Kinyarwanda or English. The survey consisted of 51 questions investigating demographics and attitudes towards self-collection for cervical cancer screening. We reported descriptive statistics stratified by urban and rural sites. In total, 169 urban and 205 rural women completed the survey. The majority of respondents at both sites had a primary school or lower education and were in a relationship. Both urban and rural respondents were open to self-collection; however, rates were higher in the rural site (79.9% urban and 95.6% rural; p-value<0.001). Similarly, women in rural areas were more likely to report feeling unembarrassed about self-collection (65.3% of urban, 76.8% of rural; p-value<0.001). Notably, almost all urban and rural respondents (97.6% urban and 98.5% rural) stated they would go for a cervical cancer pelvic examination to a nearby health center if their self-collected results indicated any concern (p-value = 0.731). Rwandan women in both urban and rural areas largely support self-collection for cervical cancer screening. Further research is needed to better understand how to implement self-collection screening services in Rwanda.

Effectiveness of Clinic-Based Patient-Led Human Papillomavirus DNA Self-Sampling among HIV-Infected Women in Uganda

In Uganda, the uptake of cervical cancer (CC) screening services is low, at 46.7%, among HIV-infected women, and only 9% of these women adhere to annual CC screening. Some studies have evaluated the possibility of community or home-based human papillomavirus (HPV) self-collected vaginal swabs, but not clinic-based HPV self-collected vaginal swabs. Therefore, we propose a study to determine the efficacy of clinic-based versus home-based HPV DNA self-sampling among HIV-infected women attending a rural HIV clinic in Uganda. We believe that a randomized, single-blinded trial would achieve this objective, and so we have chosen it to guide the study. Including a total of 382 participants from a rural HIV clinic, randomized into a ratio of 1:1 for clinic- and home-based HPV self-sampling, would allow us to appropriately ascertain the difference in the uptake of HPV self-sampling between the two arms. The Integrated Biorepository of H3 Africa Uganda Laboratory would be used as a reference laboratory for the HPV DNA extraction, typing, and sequencing. At baseline, modified Poisson regression models would be used to measure factors associated with the prevalence of HPV and uptake in both arms at baseline. Visual inspection under acetic acid (VIA), as a gold-standard test for CC to grade for CIN, would be performed at 0 and 6 months among a random sample of 75 women with a self-collected HPV sample. The difference in uptake could be determined using the intention-to-treat analysis. The difference in the groups by each variable would be summarized as the standardized mean difference (i.e., the mean difference divided by the pooled standard deviation). The predictors of the time for which participants would continue with HPV self-sampling in both arms, recovery, and Cox proportional hazards regression would be used. At the bivariate level, the associations between each independent variable and time, with the time of continuing HPV self-sampling, would be computed. Crude hazard ratios and their 95% confidence interval would be used in the presentation of the results, with p-values < 0.05 considered significant at the bivariate level. Incremental cost-effectiveness analysis (CEA) using a Markov model would be used to determine the cost of clinic-based HPV self-sampling. We believe that screening approaches to disease stratification could provide an insight into the merits and limitations of current approaches to the diagnosis of cervical cancer, and how these could eventually be implemented into HIV clinics in Uganda and other developing African countries. It is anticipated that the findings would guide the development of step-by-step guidelines for the HPV self-sampling approach.

Awareness, Knowledge and Attitude Regarding Cervical Cancer among Women Living with HIV in the Souss-Massa Region, Southern Morocco: A Cross-Sectional Study

BACKGROUND

Human immunodeficiency virus- positive women have an increased risk of precancerous lesions and invasive cervical cancer. This study aims to identify the level of awareness/knowledge and attitudes toward cervical cancer among women living with Human immunodeficiency virus in the region of Souss-Massa in southern Morocco.  Methods: This is a multicenter cross-sectional study conducted in the Souss-Massa region (southern Morocco) among women attending Human immunodeficiency virus treatment and care centers between March 2022 and September 2022. A questionnaire was used for data collection. The Chi-square test and logistic regression were deployed to identify factors associated with cervical cancer awareness among the target population.

RESULTS

A total of 494 respondents to the questionnaire, 440 (89.1%) are aware of cervical cancer. Nevertheless, 405 (82.0%) and 369 (74.7%) were unaware of cervical cancer risk factors and symptoms, respectively. Only 125 (25.3%) knew the exact frequency of cervical cancer screening among Human immunodeficiency virus positive women, whereas 221 (44.7%) had ever been tested for cervical cancer. Factors associated with women's awareness of cervical cancer are as follows:  level of education (adjusted Odds Ratio = 3.78 with 95% CI, 1.23-11.65), time since diagnosis of Human immunodeficiency virus (adjusted Odds Ratio = 4.31 with 95% CI, 1.12- 16.52), knowledge of women with cervical cancer (adjusted Odds Ratio = 6.30 with 95% CI, 1.87-21.18) and heard the pap- smear/visual inspection with acetic acid (adjusted Odds Ratio = 4.92 with 95% CI, 2.35-10.33).

CONCLUSION

The general knowledge of seropositive women regarding cervical cancer remains very low, which justifies the integration of cervical cancer prevention services with Human immunodeficiency virus care, and pinpoints the crucial role of patient education.

Mapping evidence on the acceptability of human papillomavirus self-sampling for cervical cancer screening among women in sub-Saharan Africa: a scoping review

OBJECTIVES

The objective of this scoping review was to map evidence on the acceptability of self-sampling for human papillomavirus testing (HPVSS) for cervical cancer screening among women in the sub-Saharan Africa region.

DESIGN

Scoping review.

METHODS

Using Arksey and O'Malley's framework, we searched Scopus, PubMed, Medline Ovid, Cochrane and Web of Science databases for evidence on the acceptability of HPVSS among women aged 25 years and older published between January 2011 and July 2021. We included studies that reported evidence on the acceptability of HPVSS for cervical cancer screening. Review articles and protocols were excluded. We also searched for evidence from grey literature sources such as dissertations/theses, conference proceedings, websites of international organisations such as WHO and relevant government reports. Two reviewers independently performed the extraction using a pre-designed Excel spreadsheet and emerging themes were narratively summarised.

RESULTS

The initial search retrieved 1018 articles. Of these, 19 articles were eligible and included in the review. The following themes emerged from the included articles: acceptability of HPVSS; lack of self-efficacy to perform HPVSS, complications when performing HPVSS, preferences for provider sampling or assistance; setting of HPVSS; HPVSS by vulnerable populations.

CONCLUSION

Evidence shows that HPVSS is highly acceptable for cervical cancer screening in sub-Saharan Africa. Further research exploring the acceptability of HPVSS among women residing in rural areas is required, as well as studies to determine women's preferences for HPVSS intervention including the preferred type of sampling devices. Knowledge on the acceptability and preferences for HPVSS is important in designing women-centred interventions that have the potential to increase screening coverage and participation in cervical cancer screening programmes.

Effectiveness of family-centred sexual health education and HPV self-sampling in promoting cervical cancer screening among hard-to-reach indian women in rural and tribal areas: a community-based pilot study

BACKGROUND

While cervical cancer deaths have declined steeply in high-income countries due to the widespread use of the Papanicolaou test (Pap test), the same trend has not emerged in low or middle-income countries (LMICs). Access to screening in LMICs like India is limited due to barriers such as limited healthcare infrastructures, lack of sexual health education, and stigma demarcating sexually transmitted infections (STIs). HPV self-sampling (HPV-SS), a woman-centered and at-home method for screening, can be utilized as a unique screening tool to overcome some of these barriers. Our study examined the effectiveness of HPV-SS, supported by family-centred arts-based sexual health literacy on the uptake of cervical cancer screening among hard-to-reach women in rural and remote areas in India.

METHODS

Our community-based mixed methods pilot study recruited 240 participants (120 women and 120 male partners or family members) through female Accredited Social Health Activists (ASHA) across 3 Indian villages of Shirgoan, Khodala, and Jamsar in Palghar district. Inclusion criteria included women ages 30-69 who were under or never screened (UNS) and their male partners/family members aged 18 or over. Knowledge and attitudes about cervical cancer and screening and their perceived stigma surrounding STI were assessed using validated scales prior to and after attending a 2-hour arts-based sexual health education (SHE). In addition, participants' uptake of cervical cancer screening was assessed after attendance in SHE.

FINDINGS

Results revealed significant improvement in knowledge and attitudes about cervical cancer and screening, and a reduction in the STI stigma after participation in SHE sessions (overall mean difference in Knowledge: z = 6.1 ± 2.4, P < 0.001; attitudes about Pap-test and VIA: z = 2.2 ± 8.4, P < 0.001 and z = 2.9 ± 8.2, P < 0.001; STI stigma: z = 2.8 ± 12.4, P < 0.001). 118 out of 120 female participants chose to be screened and 115 opted for HPV-SS.

CONCLUSIONS

The implementation of HPV-SS coupled with family-centered arts-based and culturally appropriate SHE is highly promising in promoting cervical cancer screening among hard-to-reach women. Evidence from our study can be used to advance public health policies and inform the scale-up of similar initiatives in other villages and states across rural India and other LMICs.

Community-integrated self-collected HPV-based cervix screening in a low-resource rural setting: a pragmatic, cluster-randomized trial

Effective approaches to improve coverage of self-collected human papillomavirus (HPV)-based cervix screening (SCS) as well as attendance at treatment for HPV-positive participants are needed to inform policy on optimal integration of cervical cancer screening programs within existing infrastructure in low-resource settings. ASPIRE Mayuge was a pragmatic cluster-randomized trial in rural Mayuge district, Uganda, comparing the superiority of two recruitment implementation strategies for SCS: Door-to-Door versus Community Health Day. Villages were randomized (unblinded) to a strategy, and participants aged 25-49 years with no previous history of hysterectomy or treatment for cervical cancer or pre-cancer were eligible. Participants completed a survey and participated in SCS. The primary outcome was rate of attendance at treatment after a positive SCS. The trial randomized 31 villages and 2,019 participants included in these analyses (Door-to-Door: 16 clusters, 1,055 participants; Community Health Day: 15 clusters, 964 participants). Among HPV-positive participants, attendance at treatment rates were 75% (Door-to-Door) and 67% (Community Health Day) (P = 0.049). Participants in the Community Health Day intervention were less likely to attend treatment compared to Door-to-Door (risk ratio = 0.78, 95% confidence interval: 0.64-0.96). No adverse events were reported. Policymakers in low-resource settings can use these results to guide implementation of SCS programs. ISRCTN registration: 12767014 . ClinicalTrials.gov registration: NCT04000503 .

Barriers to uptake of cervical cancer screening services in low-and-middle-income countries: a systematic review

OBJECTIVES

Low-and-middle-income countries (LMICs) bear a disproportionate burden of cervical cancer mortality. We aimed to identify what is currently known about barriers to cervical cancer screening among women in LMICs and propose remedial actions.

DESIGN

This was a systematic review using Medical Subject Headings (MeSH) terms in Google Scholar, PubMed, Scopus, and Web of Science databases. We also contacted medical associations and universities for grey literature and checked reference lists of eligible articles for relevant literature published in English between 2010 and 2020. We summarized the findings using a descriptive narrative based on themes identified as levels of the social ecological model.

SETTING

We included studies conducted in LMICs published in English between 2010 and 2020.

PARTICIPANTS

We included studies that reported on barriers to cervical cancer screening among women 15 years and older, eligible for cervical cancer screening.

RESULTS

Seventy-nine articles met the inclusion criteria. We identified individual, cultural/traditional and religious, societal, health system, and structural barriers to screening. Lack of knowledge and awareness of cervical cancer in general and of screening were the most frequent individual level barriers. Cultural/traditional and religious barriers included prohibition of screening and unsupportive partners and families, while social barriers were largely driven by community misconceptions. Health system barriers included policy and programmatic factors, and structural barriers were related to geography, education and cost. Underlying reasons for these barriers included limited information about cervical cancer and screening as a preventive strategy, poorly resourced health systems that lacked policies or implemented them poorly, generalised limited access to health services, and gender norms that deprioritize the health needs of women.

CONCLUSION

A wide range of barriers to screening were identified across most LMICs. Urgent implementation of clear policies supported by health system capacity for implementation, community wide advocacy and information dissemination, strengthening of policies that support women's health and gender equality, and targeted further research are needed to effectively address the inequitable burden of cervical cancer in LMICs.

The preference of women living with HIV for the HPV self-sampling of urine at a rural HIV clinic in Uganda

Background

Women living with HIV have a double risk of acquiring cervical cancer (CC) due to repeated human papilloma virus (HPV) infections resulting from reduced immunity, with CC screening being low at 46.7%.

Objectives

To determine the factors associated with the preference for HPV self-sampling using urine as well as establish its feasibility among women living with HIV attending a rural HIV clinic in Uganda.

Method

A cross-sectional study design using quantitative data collection methods was used at the HIV clinic, Luweero District Hospital, among 426 women aged between 30 and 65 years. Data were analysed using descriptive statistics and modified Poisson regression. Urine samples were analysed using a Liferiver high-risk HPV genotyping real-time polymerase chain reaction (PCR) kit to determine the prevalence of the 15 HPV subtypes. Cervical intraepithelial neoplasia 2 (CIN2) was determined by visual inspection under acetic acid (VIA) using the nurse-led approach.

Results

Most women (296/426, 70%) preferred nurse-led screening. Preference for HPV self-sampling using urine was associated with older age (46-65 years) (adjusted prevalence risk ratios [aPRR] 1.59; 95% confidence interval [CI]: 1.13-2.24), history of sexually transmitted infections (aPRR 0.74: 95% CI: 0.55-0.98) and acquisition of CC information from the television (aPRR 1.48: 95% CI: 1.09-2.02). Approximately 97% (68/70) of women living with HIV tested HPV positive with one or more subtypes. The most prevalent subtype of HPV was HPV 58 (87.1%). Only one woman tested positive with VIA.

Conclusion

Nurse-led CC screening is preferred among women living with HIV, and HPV self-sampling using urine is feasible at the HIV clinic. Therefore, educational programmes to reassure the masses about urine HPV self-sampling need to be designed.

Contribution

This study's findings provide early insights into the merits and demerits of the current HPV sample collection approaches. Hence, HPV testing should be tailored to routine HIV care in rural communities.

HPV Self-Sampling for Cervical Cancer Screening among Women Living with HIV in Low- and Middle-Income Countries: What Do We Know and What Can Be Done?

INTRODUCTION

Self-sampling has the potential to increase cervical cancer (CC) screening among women with HIV in low- and middle-income countries (LMICs). However, our understanding of how HPV self-collection studies have been conducted in women with HIV is limited. The purpose of this scoping review was to examine the extent to which the HPV self-sampling has been applied among women with HIV in LMICs.

METHOD

We conducted multiple searches in several databases for articles published between 2000 and January 2022. With the combination of keywords relating to HPV self-sampling, LMICs, and women with HIV, we retrieved over 9000 articles. We used pre-defined inclusion and exclusion criteria to select relevant studies for this review. Once a study met the inclusion criteria, we created a table to extract each study's characteristics and classified them under common themes. We used a qualitative descriptive approach to summarize the scoping results.

RESULTS

A total of 12 articles were included in the final review. Overall, 3178 women were enrolled in those studies and 2105 (66%) of them were women with HIV. The self-sampling participation rate was 92.6%. The findings of our study show that 43% of the women with HIV in 8 of the studies reviewed tested positive for high-risk HPV (hr-HPV) genotypes, indicating 4 out of 10 women with HIV in the studies are at risk of cervical cancer. The prevalence of the hr-HPV in women with HIV was 18% higher than that of HIV-negative women. Most women in the study found the self-sampling experience acceptable, easy to use, convenient, and comfortable. Self-sampling performance in detecting hr-HPV genotypes is comparable to clinician-performed sampling. However, limited access (i.e., affordability, availability, transportation), limited knowledge about self-screening, doubts about the credibility of self-sampling results, and stigma remain barriers to the wide acceptance and implementation of self-sampling. In conclusion, the findings of this review highlight that (a) the prevalence of hr-HPV is higher among women with HIV than HIV-negative women, (b) self-sampling laboratory performance is similar to clinician-performed sampling, (c) the majority of the women participated in self-sampling, which could likely increase the cervical cancer screening uptake, and (d) women with HIV reported a positive experience with self-sampling. However, personal, environmental, and structural barriers challenge the application of self-sampling in LMICs, and these need to be addressed.

“By the time they run into the hospital, their life is already at stake”: a qualitative study of healthcare professional perceptions on priorities for cervical cancer policy in Uganda

Background

Cervical cancer (CxCa) incidence in Uganda is three times the global average and a leading cause of mortality for women. While there is funding and infrastructure to support HIV control in Uganda, these are not in place for CxCa prevention and control. This study was conducted to explore the knowledge and perceptions of HIV professionals in Uganda to identify perceived barriers and facilitators to CxCa screening and treatment among women living with HIV (WLHIV) as a basis to guide and inform policies and programs for CxCa prevention and control, including service integration.

Methods

This study used qualitative interviews to obtain primary data from professionals working in the HIV field in Uganda conducted from September 2020 to January 2022. Participants were identified through purposive and snowball sampling and consulted with colleagues at local service and academic agencies in Kampala. Both written and verbal informed consent was obtained. Hour-long interviews were conducted virtually and in person and recorded. Interviews consisted of open-ended questions exploring perspectives on, knowledge about, and practices surrounding HPV and CxCa among WLHIV in Uganda. Transcripts were analyzed and coded via MAXQDA software to identify facilitators and barriers to HPV vaccination, CxCa screening and treatment.

Results

Fifty key informant (KI) interviews were conducted. Analysis revealed two themes regarding priorities for cervical cancer policy in Uganda after KIs reflected on improving barriers to CxCa care. These were: (1) decentralization of care through integration of services and (2) leadership on a national level by increasing funding and organizing advocacy initiatives. Practical recommendations identified by KI that derived from these themes included leveraging community institutions and mass media campaigns to target misconceptions surrounding screening, making CxCa screening opt-out and integrated with HIV care, strengthening a centralized database, organizing mass roll-out of self-testing, and organizing training of healthcare workers.

Conclusions

Key informants call for solutions that address individual, community, and national barriers of cervical cancer care and emphasize the need for a strong national cervical cancer policy to coordinate currently fragmented services and the political will to adequately fund these.

Anal and cervical human papillomavirus genotypes in women co-infected with human immunodeficiency virus: A systematic review

Human papillomavirus (HPV) and human immunodeficiency virus (HIV) infections are sexually transmitted. There are several HPV genotypes and clinical manifestations. Determining which genotypes circulate worldwide and/or in specific geographic areas can help with prevention programs and vaccine distribution. This systematic review aimed to investigate the most frequent anal and cervical HPV genotypes in women co-infected with HPV/HIV. The PubMed, Scientific Electronic Library Online, and Latin American and Caribbean Literature in Health Sciences databases were used to search for articles published between January 2015 and August 2021, and the included articles followed the defined selection criteria. Based on the 51 articles included, HPV16 was the most prevalent (41%) genotype, followed by HPV52 (17%) and HPV58 (14%). Based on the comparative analyses of the HIV-negative women with HPV and the HPV/HIV co-infected groups, HPV16 was frequent in both groups; HPV58, HPV31, and HPV52 were more frequent in the co-infected group; and HPV18 was more common in HIV-negative women with HPV. HPV/HIV co-infected women most frequently presented the HPV genotypes 16, 58, and 52, whereas HIV-negative women with HPV had a higher frequency of HPV16, HPV18, and HPV52 genotypes. The results indicate the importance of genotype surveillance as a strategy to improve preventive measures against HPV infection and its complications.

HPV self-sampling for cervical cancer screening: a systematic review of values and preferences

INTRODUCTION

The WHO recommends human papillomavirus (HPV) cervical self-sampling as an additional screening method and HPV DNA testing as an effective approach for the early detection of cervical cancer for women aged ≥30 years. This systematic review assesses end user's values and preferences related to HPV self-sampling.

METHODS

We searched four electronic databases (PubMed, Cumulative Index to Nursing and Allied Health Literature, Latin American and Caribbean Health Sciences Literature and Embase) using search terms for HPV and self-sampling to identify articles meeting inclusion criteria. A standardised data extraction form was used to capture study setting, population, sample size and results related to values and preferences.

RESULTS

Of 1858 records retrieved, 72 studies among 52 114 participants published between 2002 and 2018 were included in this review. Almost all studies were cross-sectional surveys. Study populations included end users who were mainly adolescent girls and adult women. Ages ranged from 14 to 80 years. Most studies (57%) were conducted in high-income countries. Women generally found HPV self-sampling highly acceptable regardless of age, income or country of residence. Lack of self-confidence with collecting a reliable sample was the most commonly cited reason for preferring clinician-collected samples. Most women preferred home-based self-sampling to self-sampling at a clinic. The cervical swab was the most common and most accepted HPV DNA sampling device.

CONCLUSIONS

HPV self-sampling is generally a highly accepted method of cervical cancer screening for end users globally. End user preferences for self-sampling device, method and setting can inform the development of new and expanded interventions to increase HPV screening.

Women's experiences in a community-based screen-and-treat cervical cancer prevention program in rural Malawi: a qualitative study

BACKGROUND

Malawi has the world's highest cervical cancer incidence and mortality due to high rate of HIV coupled with inadequate screening and treatment services. The country's cervical cancer control program uses visual inspection with acetic acid (VIA) and cryotherapy, but screening is largely limited by poor access to facilities, high cost of cryotherapy gas, and high loss-to-follow-up. To overcome these limitations, we implemented a community-based screen-and-treat pilot program with VIA and thermocoagulation. Through a qualitative study, we explore the experiences of women who underwent this community-based pilot screening program.

METHODS

We implemented our pilot program in rural Malawi and conducted an exploratory qualitative sub-study. We conducted in-depth interviews with women who were treated with thermocoagulation during the program. We used semi-structured interviews to explore screen-and-treat experience, acceptability of the program and attitudes towards self-sampling for HPV testing as an alternative screening method. Content analysis was conducted using NVIVO v12.

RESULTS

Between July - August 2017, 408 participants eligible for screening underwent VIA screening. Thirty participants had VIA positive results, of whom 28 underwent same day thermocoagulation. We interviewed 17 of the 28 women who received thermocoagulation. Thematic saturation was reached at 17 interviews. All participants reported an overall positive experience with the community-based screen-and-treat program. Common themes were appreciation for bringing screening directly to their villages, surprise at the lack of discomfort, and the benefits of access to same day treatment immediately following abnormal screening. Negative experiences were rare and included discomfort during speculum exam, long duration of screening and challenges with complying with postprocedural abstinence. Most participants felt that utilizing self-collected HPV testing could be acceptable for screening in their community.

CONCLUSIONS

Our exploratory qualitative sub-study demonstrated that the community-based screen-and-treat with VIA and thermocoagulation was widely accepted. Participants valued the accessible, timely, and painless thermocoagulation treatment and reported minimal side effects. Future considerations for reaching rural women can include community-based follow-up, cervical cancer education for male partners and self-sampling for HPV testing.

Knowledge, attitude and practice of cervical cancer screening among women infected with HIV in Africa: Systematic review and meta-analysis

BACKGROUND

To establish successful strategies and increasing the utilization of preventive services, there is a need to explore the extent to which the general female population is aware and use the service for cervical cancer-screening among women infected with HIV in Africa. Available evidences in this regard are controversial and non-conclusive on this potential issue and therefore, we estimated the pooled effect of the proportion of knowledge, attitude and practice of HIV infected African women towards cervical cancer screening to generate evidence for improved prevention strategies.

METHODS

We applied a systematic review and meta-analysis of studies conducted in Africa and reported the proportion of knowledge, attitude and practice towards cervical cancer screening. We searched electronic databases: PubMed/Medline, SCOPUS, ScienceDirect, Web of science, Cumulative Index of Nursing and allied Health Sciences (CINAHL) and Google scholar databases to retrieve papers published in English language till August 2020. We used random-effects model to estimate the pooled effect, and funnel plot to assess publication bias. The registration number of this review study protocol is CRD42020210879.

RESULTS

In this review, we included eight published papers comprising 2,186 participants. The estimated pooled proportion of knowledge of the participants was 43.0% (95%CI:23.0-64.0) while the pooled estimates of attitudes and practices were 38.0% (95%CI: 1.0-77.0) and 41.0% (95%CI: 4.0-77.0), respectively. The proportion of the outcome variables were extremely heterogeneous across the studies with I2> 98%).

CONCLUSION

The pooled estimates of knowledge, attitude and practice were lower than other middle income countries calls for further activities to enhance the uptake of the services and establish successful strategies.

Predictors of cervical cancer screening uptake in two districts of Central Uganda

Uganda's cervical cancer age standardized incidence rate is four times the global estimate. Although Uganda's ministry of health recommends screening for women aged 25-49 years, the screening remains low even in the most developed region (Central Uganda) of the country. This study examined the demographic, social, and economic predictors of cervical cancer screening in Central Uganda with the aim of informing targeted interventions to improve screening. The cross-sectional survey was conducted in Wakiso and Nakasongola districts in Central Uganda. A total of 845 women age 25-49 years participated in the study. Data were analyzed at bivariate and multivariate levels to examine the predictors of CC (cervical cancer) screening. Only 1 in 5 women (20.6%) had ever screened for cervical cancer. Our multivariate logistic regression model indicated that wealth index, source of information, and knowledge about CC and CC screening were significantly associated with cervical cancer screening. The odds of cervical cancer screening were higher among rich women compared with poor women [AOR = 1.93 (95%CI: 1.06-3.42), p = 0.031)], receiving information from health providers compared with radios [AOR = 4.14 (95%CI: 2.65-6.48), p<0.001, and being more knowledgeable compared with being less knowledgeable about CC and CC screening [AOR = 2.46 (95%CI: 1.49-3.37), p<0.001)]. Overall cervical cancer screening uptake in central Uganda was found to be low. The findings of the study indicate that women from a wealthy background, who had been sensitized by health workers and with high knowledge about CC and CC screening had higher odds of having ever screened compared with their counterparts. Efforts to increase uptake of screening must address disparities in access to resources and knowledge.

HPV genoprevalence and HPV knowledge in young women in Mongolia, five years following a pilot 4vHPV vaccination campaign

BACKGROUND

In a 2012 pilot, 9111 Mongolian girls aged 11-17 years received three doses of the quadrivalent (4vHPV) vaccine, Gardasil®. This is the first study to measure early vaccine effectiveness and assess knowledge and attitudes of young women in Mongolia in relation to the human papillomavirus (HPV), the vaccine and cervical cancer.

METHODS

A cohort of women vaccinated in 2012 (n = 726) and an unvaccinated cohort (n = 790) provided self-administered vaginal swabs for detection of high-risk HPV genotypes 16, 18/45, 31, 33, 35, 39, 51, 52, 56, 58, 59, 66, 68 five years following vaccination. Participant knowledge and attitudes were assessed through a questionnaire.

RESULTS

A total of 1882 questionnaires and 1516 self-administered vaginal swabs were analyzed. The prevalence of any HRHPV was 39.5% among both cohorts. The prevalence of vaccine-targeted HPV types was significantly lower in the vaccinated cohort than unvaccinated: 4.8% and 17.2% respectively. The 4vHPV was shown to be protective against HRHPV 16, 18/45 with 75% vaccine effectiveness. Participant knowledge was low.

CONCLUSIONS

This study demonstrates that the 4vHPV is associated with reduced vaccine-targeted HPV detection rates in young Mongolian women. The questionnaire results highlight a need for awareness-raising initiatives in Mongolia on HPV, the vaccine and cervical cancer.

HPV self-sampling acceptability and preferences among women living with HIV in Botswana

OBJECTIVE

To assess the acceptability and preferences of HPV screening with self-sampling and mobile phone results delivery among women living with HIV (WLWH) in Botswana, as an alternative to traditional speculum screening.

METHODS

WLWH aged 25 years or older attending an infectious disease clinic in Gaborone were enrolled in a cross-sectional study between March and April 2017. Women self-sampled with a flocked swab, had a speculum exam, and completed an interviewer-administered questionnaire about screening acceptability, experiences, and preferences.

RESULTS

Of the 104 WLWH recruited, 98 (94%) had a history of traditional screening. Over 90% agreed self-sampling was easy and comfortable. Ninety-five percent were willing to self-sample again; however, only 19% preferred self-sampling over speculum exam for future screening. Preferences differed by education and residence with self-sampling being considered more convenient, easier, less embarrassing, and less painful. Speculum exams were preferred because of trust in providers' skills and women's low self-efficacy to sample correctly. Almost half (47%) preferred to receive results via mobile phone call. Knowledge of cervical cancer did not affect preferences.

CONCLUSION

HPV self-sampling is acceptable among WLWH in Botswana; however, preferences vary. Although self-sampling is an important alternative to traditional speculum screening, education and support will be critical to address women's low self-efficacy to self-sample correctly.

Knowledge of HPV/cervical cancer and acceptability of HPV self-sampling among women living with HIV: A scoping review

Cervical cancer rates are disproportionately high among women living with the human immunodeficiency virus (wlhiv). Cervical cancer is preventable through hpv screening, regular Pap tests, and early cancer detection. Evidence indicates that hpv and cervical cancer screening are suboptimal among wlhiv, who face a myriad of access barriers. Considering that screening is an effective first-line defense to cervical cancer, we conducted a scoping review with the aim of gaining a better understanding about: (1) the knowledge and perceptions of hpv and cervical cancer screening among wlhiv; and (2) the acceptability of self-sampling for hpv among wlhiv. We searched five electronic databases for peer-reviewed articles that were published in English within the last ten years, reported on studies with hiv-positive women who were aged 16 or older, and satisfied the topics of the review. A total of 621 articles were found. After accounting for duplicates and unmet criteria, 17 articles and 1 abstract, reporting on studies in the United States and Africa, were included in this review. The review highlighted that most wlhiv had inadequate knowledge of hpv transmission and cervical cancer prevention, which influenced their perceptions of risk and susceptibility. Screening barriers included misconceptions about Pap tests, fear of diagnosis of serious illness, perceived pain, embarrassment, bodily modesty, and limited access to female health care providers. This review also affirms that self-sampling is an acceptable and promising screening option for wlhiv. Implications for policy, research, and practice are discussed.

Cervical cancer screening and treatment in Uganda

Cervical cancer is the leading cause of cancer death among women in Uganda. Given the high prevalence of genital human papillomavirus infection, the current unavailability of radiotherapy, and the absence of a national cervical cancer prevention and control program, these deaths will likely increase. Efforts to organize an effective cervical cancer screening and treatment program will require adequate financial resources, the development of infrastructure, training needed manpower, and surveillance mechanisms of the targeted women. Screening with VIA (visual inspection with acetic acid) and HPV DNA testing on self-collected samples with processing at a specific site could, for the first time, make national, large-scale population-based screening feasible in Uganda. Combining screening efforts with timely treatment of all screen positives for HPV infection can prevent progression to invasive cervical cancer. To date, this is the most effective intervention in closing the current prevention gap.

Training of health professionals, ongoing construction of new radiotherapy bunkers, and opening of regional centers are all geared towards improving cervical cancer care in Uganda. The Uganda Cancer Institute Bill establishes the Institute as a semi-autonomous agency mandated to undertake and coordinate the prevention and treatment of cancer. Its implementation will be a milestone in cervical cancer prevention and control. However, execution will require political will and an increase in domestic and international investment.

•

Screening in low resource settings for cervical cancer is priority.

•

In the absence of radiotherapy neoadjuvant chemotherapy can be used to down size tumour to operable size.

•

There's lack of personnel with specialized skills.
