Abstract
BACKGROUND Data on the occurrence of cervical precancer and cancer among women living with HIV (WLHIV) in Latin American countries (LAC) are scarce and highly heterogeneous. METHODS We conducted a systematic review summarizing data about the incidence/prevalence of invasive cervical cancer (CC) and high-grade precancerous lesions among WLHIV in LAC. Literature in PubMed and LILACS was searched. The primary outcome was invasive cancer incidence, and prevalence of high-grade lesions as key indicators for the WHO CC elimination strategy. Individual reports on invasive cancer incidence and prevalence of precancerous lesions were obtained, and a random effects meta-analysis was conducted for the latter. RESULTS In total, 34,343 WLHIV from four studies reporting CC incidence in seven LAC were included, and 6079 WLHIV from 17 studies reporting prevalence of precancerous lesions in three LAC were included. CC incidence ranged between 136.0 and 398.4 per 100,000 WLHIV (with or without antiretroviral therapy). The weighted prevalence of high-grade lesions was 4.1% (95%CI: 3.8%-6.0%) with a double peak at ages 20-24 and 35-39 years. Differences in prevalence of high-grade lesions were also observed by screening approach: co-testing (11.9%), colposcopy (6.0%), cytology (4.2%), and HPV tests (3.2%). CONCLUSIONS The high incidence of invasive cancer and prevalence of high-grade lesions underline challenges to reach the WHO's elimination goal of CC incidence below four per 100,000 among WLHIV. Moreover, the high prevalence of high-grade lesions at younger ages than in the general population is a call to accelerate the implementation of the new WHO screening recommendations in WLHIV.

Zhao R, Sekar P, Bennis SL, Kulasingam S. A systematic review of the association between smoking exposure and HPV-related cervical cell abnormality among women living with HIV: Implications for prevention strategies. Prev Med 2023; 170:107494. [PMID: 37001607 DOI: 10.1016/j.ypmed.2023.107494] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/14/2022] [Revised: 03/23/2023] [Accepted: 03/27/2023] [Indexed: 04/05/2023]
Abstract
This study aims to evaluate the association between smoking exposure and human papillomavirus (HPV)-related cervical abnormalities among women living with HIV (WLWH). By conducting a systematic review of the current literature, we evaluated the association between current active smoking and/or exposure to secondhand smoke (SHS) and the risk of cervical HPV incidence, prevalence, and clearance, as well as high-grade cervical intraepithelial neoplasm (HGCIN) incidence, prevalence, progression, and regression among WLWH. We conducted the literature search in Ovid Medline, Embase, and Scopus following the PRISMA guidelines. We determined the risk of bias of included studies using the Risk of Bias Assessment Tool for Nonrandomized Studies. Studies with the same effect measure were combined for a pooled estimate. We identified 15 studies that met the inclusion criteria for the final analysis, with a limited number of studies evaluating each study question. Among WLWH, current active smoking is associated with an increased risk of new HPV infections (HR = 1.33, 95% CI 1.10-1.60), HPV prevalence (ORpooled = 1.55, 95% CI 1.26-1.91), HGCIN incidence (HR = 1.5, 95% CI 1.2-2.0), and HGCIN prevalence (PR = 3.69, 95% CI 1.54-8.78). There was no significant association between current active smoking and HPV clearance. We did not identify any study that evaluated the association between SHS exposure and HPV-related cervical abnormalities among WLWH. Active smoking increases the risk of HPV infection and pre-cancer lesion development in WLWH. Considering smoking as an additional risk factor when designing tailored cervical cancer screening programs for WLWH is necessary in high smoking prevalence regions.

Risk Analysis Stratification of CIN 2+ Development in a Cohort of Women Living with HIV with Negative Pap Smear and HR-HPV Test during a Long-Term Follow-Up. Vaccines (Basel) 2023; 11:vaccines11020265. [PMID: 36851143 PMCID: PMC9961029 DOI: 10.3390/vaccines11020265] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2022] [Revised: 01/10/2023] [Accepted: 01/21/2023] [Indexed: 01/28/2023] Open
Abstract
BACKGROUND Women living with Human Immunodeficiency Virus are at higher risk of cervical cancer and precancer compared to women without HIV infection. The aim of the study is to evaluate the risk factors for the development of CIN2+ in a cohort of WLWH with negative colposcopy and cytology during a long follow-up period. METHODS We enrolled, in a multicentric retrospective cohort study, WLWH who attended the colposcopic services from 1999 to 2019. Patients with a normal Pap smear, a negative HR-HPV test, and at least one year of follow-up were considered for the anlysis. RESULTS The five-year cumulative incidence of histologically confirmed HSIL was 8.3% (95% CI = 2.6-13.6) among subjects with a CD4+ cell count of <200 cells/µL at any visit and 2.1% (95% CI = 0.7-3.4, p = 0.001) in women with a CD4+ cell count of persistently >200 cells/µL. In women with persistent HR-HPV infection, the five-year cumulative incidence of CIN 2+ was 6% (95% CI = 1.6-10.2) versus 2% (95% CI = 0.4-3.6, p = 0.012) in women without HPV infection. An HIV viremia of >200 copies/mL, a CD4+ cell count of <200 cells/µL, persistent HR-HPV infection, and smoking ≥10 cigarettes/day were all independent and statistically significant risk factors associated with the development of CIN2+ during follow-up. CONCLUSIONS WLWH with good immune status and negative Pap smear and HR-HPV test have a low risk for CIN2+.

Diagnostic accuracy of cervical cancer screening strategies for high-grade cervical intraepithelial neoplasia (CIN2+/CIN3+) among women living with HIV: A systematic review and meta-analysis. EClinicalMedicine 2022; 53:101645. [PMID: 36187721 PMCID: PMC9520209 DOI: 10.1016/j.eclinm.2022.101645] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/28/2022] [Revised: 08/11/2022] [Accepted: 08/12/2022] [Indexed: 01/25/2023] Open
Abstract
BACKGROUND We systematically reviewed the diagnostic accuracy of cervical cancer screening and triage strategies in women living with HIV (WLHIV). METHODS Cochrane Library, Embase, Global Health and Medline were searched for randomised controlled trials, prospective or cross-sectional studies published from database inception to 15 July 2022 reporting diagnostic accuracy of tests in cervical cancer screening and triage of screen-positive WLHIV. Studies were included if they reported the diagnostic accuracy of any cervical cancer screening or triage strategies for the detection of histologically-confirmed high-grade cervical intraepithelial neoplasia (CIN2+/CIN3+) among WLHIV. Summary data were extracted from published reports. Authors were contacted for missing data where applicable. Sensitivity and specificity estimates for CIN2/3+ were pooled using models for meta-analysis of diagnostic accuracy data. Study quality was assessed using the QUADAS-2 tool for the quality assessment of diagnostic accuracy studies. PROSPERO registration:CRD42020189031. FINDINGS In 38 studies among 18,737 WLHIV, the majority (n=19) were conducted in sub-Saharan Africa. The pooled prevalence was 12.0% (95%CI:9.8-14.1) for CIN2+ and 6.7% (95%CI:5.0-8.4) for CIN3+. The proportion of screen-positive ranged from 3-31% (visual inspection using acetic acid[VIA]); 2-46% (high-grade squamous intraepithelial lesions, and greater [HSIL+] cytology); 20-64% (high-risk[HR]-HPV DNA). In 14 studies, sensitivity and specificity of VIA were variable limiting the reliability of pooled estimates. In 5 studies where majority had histology-confirmed CIN2+, pooled sensitivity was 56.0% (95%CI:45.4-66.1; I2=65%) for CIN2+ and 65.0% (95%CI:52.9-75.4; I2 =42%) for CIN3+; specificity for <CIN2 was 73.8% (95%CI:59.8-84.2, I2=94%). Cytology was similarly variable (sensitivity of ASCUS+ for CIN2+ range: 58-100%; specificity: 9-96%). In 28 studies, sensitivity of tests targeting 14-HR-HPV types was high (91.6%, 95%CI:88.1-94.1; I2=45% for CIN2+ and 92.5%, 95%CI:88.4-95.2; I2=32%) for CIN3+); but specificity for <CIN2 was low (62.2% (95%CI:57.9-66.4;I2=92%). Restriction to 8-HR-HPV increased specificity (65.8%; Relative specificity[RSpec] vs. 14-HR-HPV=1.17; 95%CI:1.10-1.24) with no significant change in sensitivity (CIN2+:85.5%; Relative Sensitivity[RSens]=0.94, 95%CI: 0.89-1.00; CIN3+:90%; RSens=0.96, 95%CI:0.89-1.03). VIA triage of 14-HR-HPV positive women decreased sensitivity for CIN2+ compared to HPV-DNA test alone (64.4% vs. 91.6%; RSens=0.68, 95%CI:0.62-0.75). INTERPRETATION HPV-DNA based approaches consistently showed superior sensitivity for CIN2+/CIN3+ compared to VIA or cytology. The low specificity of HPV-DNA based methods targeting up to 14-HR-HPV could be improved significantly by restricting to 8-HR-HPV with only minor losses in sensitivity, limiting requirement for triage for which optimal approaches are less clear.

Abstract
We carried out a systematic review to summarize available data regarding prevalence of high-risk human papillomavirus (HR-HPV) among women living with HIV (WLHIV) in Latin America and the Caribbean (LAC). A literature search in PubMed and LILACS was conducted and supplemented with cross-referencing and grey literature. The primary outcome was prevalence of HR-HPV by age as a major determinant of HPV infection. Pooled prevalence and weighted averages were obtained. A random effects meta-analysis conducted for HPV- and HIV-associated factors. In total, 6157 women from 19 cross-sectional studies were included. Weighted prevalence of HR-HPV in WLHIV was 51.0% (95% CI 42.8-59.1, I2 = 97.4%) with a bimodal trend by age. No association between antiretroviral therapy and HR-HPV prevalence was observed, but low CD4 cell count was associated (PR 1.64, 95% CI 1.07-2.52). Although not significant, a higher HR-HPV prevalence was observed with Hybrid Capture 2 versus PCR. The high prevalence of HR-HPV among WLHIV in LAC underlines the need for improved cervical cancer prevention and early detection in this vulnerable population. Moreover, the high prevalence across age groups, and particularly in young women, deserves careful consideration for defining target populations of HPV-based screening and HPV immunization programs.

Abstract
OBJECTIVE We systematically investigated the prevalence of HPV, high-risk HPV and its genotypes in women living with human immunodeficiency virus (WLHIV) in Brazil. METHODS A systematic search was performed up to 15 December 2020. We included studies that used molecular methods for HPV detection in cervical samples and reported the prevalence of HPV in Brazilian WLHIV. The pooled prevalence of HPV, high-risk HPV (HR HPV) and HPV types and their 95% confidence interval (CI) were estimated. Subgroup analyses and meta-regression were conducted. RESULTS Thity-seven studies accounting for 8,436 WLHIV were included. The pooled HPV prevalence was 62% (95%CI 55-68%; I2 = 96.98%; P < 0.001). Prevalence of high-risk HPV was 40% (95%CI, 54-68%; I2 = 94.23%; P < 0.001). We found a wide variety of high-risk HPV genotypes. The high-risk HPV types most reported were HPV 16 (16%) and HPV 58 (6%). We found an increasing ratio of positivity from normal cervix to cancer. There were different factors associated with high-risk HPV, with low CD4+ count the most frequent. CONCLUSION The increase in the ratio of high-risk HPV positivity from normal cervix to carcinogenic lesions highlights the need to implement well-established testing for high-risk HPV in this population.

Abstract
Cervical cancer is a public health problem and has devastating effects in low-to-middle-income countries (LTMICs) such as the sub-Saharan African (SSA) countries. Infection by the human papillomavirus (HPV) is the main cause of cervical cancer. HIV positive women have higher HPV prevalence and cervical cancer incidence than their HIV negative counterparts do. Concurrent HPV/HIV infection is catastrophic, particularly to African women due to the high prevalence of HIV infections. Although various studies show a relationship between HPV, HIV and cervical cancer, there is still a gap in the knowledge concerning the precise nature of this tripartite association. Firstly, most studies show the relationship between HPV and cervical cancer at genomic and epigenetic levels, while the transcriptomic landscape of this relationship remains to be elucidated. Even though many studies have shown HPV/HIV dual viral pathogenesis, the dual molecular oncoviral effects on the development of cervical cancer remains largely uncertain. Furthermore, the effect of highly active antiretroviral therapy (HAART) on the cellular splicing machinery is unclear. Emerging evidence indicates the vital role played by host splicing events in both HPV and HIV infection in the development and progression to cervical cancer. Therefore, decoding the transcriptome landscape of this tripartite relationship holds promising therapeutic potential. This review will focus on the link between cellular splicing machinery, HPV, HIV infection and the aberrant alternative splicing events that take place in HIV/HPV-associated cervical cancer. Finally, we will investigate how these aberrant splicing events can be targeted for the development of new therapeutic strategies against HPV/HIV-associated cervical cancer.

Abstract
BACKGROUND The risk of death from complications related to cancer of the cervix is a main health problem over the course of a woman's life in low income countries. It commonly affects women infected with HIV. Therefore, screening women infected with HIV should start in low income countries, including Ethiopia. METHODS We conducted an institution based cross-sectional study from September 1st, 2015 to December 30th, 2015. During the study, 435 women were included in the study. The data were collected through face to face interviews and patient chart review using pre-tested and structured questionnaires. Data was also collected through visual inspection with acetic acid applied for screening and treatment. Data was entered into Epi-info version 7, cleaned and analyzed using SPSS version 20. Logistic regression analysis fitted and odds ratio with 95% confidence interval were computed. RESULTS The overall prevalence of pre-cancerous lesions of the cervix was 20.2% (95%CI: 13%, 29%). Having more than one lifetime sexual partner (AOR=2.91, 95%CI:1.13, 7.52), a history of sexually transmitted disease (AOR=4.04, 95%CI: 2.19, 7.44), age at first birth less than 18 years (AOR=3.36, 95%CI: 1.79, 5.01) and baseline CD4 count less than 200 cells/mm3 (AOR=7.51, 95%CI: 3.58, 15.68) were significantly associated with pre-cancerous lesion of the cervix. CONCLUSION This study points out the prevalence of pre-cancerous lesions of the cervix is high. Thus, the findings recommend raising of a screening strategy for cervical intraepithelial neoplasia for all women living with HIV should be undertaken. In addition, awareness creation about the impact of multiple sexual partner, promotion of early HIV diagnosis and timely baseline CD4 cell count is important.

Abstract
TNF-α is involved in HPV infection control by triggering cell signaling through binding in specific receptors TNFR1 and TNFR2. Genetic polymorphisms in these receptors may influence TNF-α signaling. Herein, we investigated TNFR1 rs767455 and rs2234649 single nucleotide polymorphisms, and TNFR1 protein expression in cervical squamous intraepithelial lesions (SIL) to identify their role in cervical pre-malignant development. SIL patients (n = 179) and healthy volunteers (n = 227) were enrolled for TNFR1 genotyping analysis by PCR-RFLP in blood samples and TNFR1 protein expression in cervical tissue by immunohistochemistry. No statistical differences regard genotypes and allelic frequencies for both polymorphisms were observed. Cervical TNFR1-expressing cells were rare in epithelium and basal layer regardless the groups. However, a progressive increase in infiltrating cells was observed in the stromal area, mainly in high SIL (HSIL) group compared to low SIL (LSIL, p < 0.001) and control (p < 0.001) groups. TNFR1-expressing cells frequency was higher in TNFR1 rs767455AG/GG (p < 0.001), and in rs2234649AA (p < 0.001) genotypes carries in HSIL subgroup. These data indicated that TNFR1-expression is abrogated in cervical epithelium, where HPV-induced pre-malignant lesion occurs, increasing its frequency in inflammatory cells in stroma, and is genetically controlled by TNFR1 rs767455AG/GG and rs234649AA genotypes. These biomarkers may be useful to identify cervical precancerous lesions progression.

Abstract
Abstract Objective: To identify the vulnerabilities of women with human immunodeficiency virus to cervical cancer. Methods: Cross-sectional study carried out in a clinic with 152 adult women with HIV, by means of the application of a structured form comprising several types of vulnerability. Results: Related to individual vulnerability, were prevalent the age above 29 years (87.5%), education higher than eight years of study (53.3%) and family income lower than two minimum wages (94.1%). The majority reported active sexual life (81.6%) and non-use of condoms (57.2%). Regarding the social vulnerability, 56.6% were unemployed. About programmatic vulnerability, 44.0% of women underwent a prevention exam in a period of more than one year. Women with more schooling (p = 0.007), employed (p = 0.000) and that did not use illicit drugs (p = 0.000) underwent the preventive exam in proper frequency. Conclusion: In this study, were identified individual, social and programmatic vulnerabilities for cervical cancer in women with HIV.

Abstract
In this retrospective case-control study, we analyse data of 48 HIV-positive pregnant patients, versus a control group of 99 HIV-negative pregnant women, followed as outpatients by our department from 2009 to 2014. The aims of the study were to investigate the prevalence, persistence and progression of cervical squamous intraepithelial lesions (SIL) in each group and to correlate colpo-cytological lesions to the socio-demographic and clinical-laboratory findings in the HIV + pregnant women. In our study we observed that immunosuppression, HPV infection and vaginal coinfections were predictive of cervical lesions. Pap smear and colposcopy should be part of routine care for HIV-infected pregnant women because these lesions behave aggressively in these patients. Success of prevention depends on massive access of patients to screening. HAART reduces viral load and maintains CD4 count and can affect progression of SIL. Multidisciplinary services on the same site appear to be one promising strategy to improve compliance in patients. Impact Statement What is already known on this subject: Our study provided novel information on a highly vulnerable population of young HIV + pregnant women. What the results of this study add: We observed that immunosuppression, HPV infection and vaginal coinfections were predictive of cervical lesions remarkable with colposcopy. We could consider these important risk factors to evaluate to establish an appropriate strategy of management for these patients. What the implications are of these findings for clinical practice and/or further research: Association of the risk between SIL presence and HIV and HPV infection also deserves additional investigation. We believe that Pap smears and colposcopies should be part of the routine care for HIV-infected women because these lesions behave particularly aggressively in these patients.

Association of antiretroviral therapy with high-risk human papillomavirus, cervical intraepithelial neoplasia, and invasive cervical cancer in women living with HIV: a systematic review and meta-analysis. Lancet HIV 2017; 5:e45-e58. [PMID: 29107561 PMCID: PMC5757426 DOI: 10.1016/s2352-3018(17)30149-2] [Citation(s) in RCA: 157] [Impact Index Per Article: 22.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2016] [Revised: 07/15/2017] [Accepted: 08/02/2017] [Indexed: 12/15/2022]
Abstract
BACKGROUND The interactions between antiretroviral therapy (ART) and high-risk human papillomavirus (HPV) and cervical lesions in women living with HIV are poorly understood. We reviewed the association of ART with these outcomes. METHODS We did a systematic review and meta-analysis by searching MEDLINE and Embase databases for cross-sectional or cohort studies published in English between Jan 1, 1996, and May 6, 2017, which reported the association of ART with prevalence of high-risk HPV or prevalence, incidence, progression, or regression of histological or cytological cervical abnormalities, or incidence of invasive cervcal cancer. Studies were eligible if they reported the association of combination ART or highly active ART use with the following outcomes: high-risk HPV prevalence; squamous intraepithelial lesion (SIL) or cervical intraepithelial neoplasia (CIN) prevalence, incidence, progression, or regression; and invasive cervical cancer incidence among women living with HIV. We did random-effects meta-analyses to estimate summary statistics. We examined heterogeneity with the I2 statistic. This review is registered on the PROSPERO database at the Centre of Reviews and Dissemination, University of York, York, UK (registration number CRD42016039546). FINDINGS We identified 31 studies of the association of ART with prevalence of high-risk HPV (6537 women living with HIV) and high grade cervical lesions (HSIL-CIN2+; 9288 women living with HIV). Women living with HIV on ART had lower prevalence of high-risk HPV than did those not on ART (adjusted odds ratio [aOR] 0·83, 95% CI 0·70-0·99; I2=51%, adjusted for CD4 cell count and ART duration), and there was some evidence of association with HSIL-CIN2+ (0·65, 0·40-1·06; I2=30%). 17 studies reported the association of ART with longitudinal cervical lesion outcomes. ART was associated with a decreased risk of HSIL-CIN2+ incidence among 1830 women living with HIV (0·59, 0·40-0·87; I2=0%), SIL progression among 6212 women living with HIV (adjusted hazard ratio [aHR] 0·64, 95% CI 0·54-0·75; I2=18%), and increased likelihood of SIL or CIN regression among 5261 women living with HIV (1·54, 1·30-1·82; I2=0%). In three studies among 15 846 women living with HIV, ART was associated with a reduction in invasive cervical cancer incidence (crude HR 0·40, 95% CI 0·18-0·87, I2=33%). INTERPRETATION Early ART initiation and sustained adherence is likely to reduce incidence and progression of SIL and CIN and ultimately incidence of invasive cervical cancer. Future cohort studies should aim to confirm this possible effect. FUNDING UK Medical Research Council.

Abstract
BACKGROUND Cervical cancer screening has traditionally been based on cervical cytology. Given the aetiological relationship between human papillomavirus (HPV) infection and cervical carcinogenesis, HPV testing has been proposed as an alternative screening test. OBJECTIVES To determine the diagnostic accuracy of HPV testing for detecting histologically confirmed cervical intraepithelial neoplasias (CIN) of grade 2 or worse (CIN 2+), including adenocarcinoma in situ, in women participating in primary cervical cancer screening; and how it compares to the accuracy of cytological testing (liquid-based and conventional) at various thresholds. SEARCH METHODS We performed a systematic literature search of articles in MEDLINE and Embase (1992 to November 2015) containing quantitative data and handsearched the reference lists of retrieved articles. SELECTION CRITERIA We included comparative test accuracy studies if all women received both HPV testing and cervical cytology followed by verification of the disease status with the reference standard, if positive for at least one screening test. The studies had to include women participating in a cervical cancer screening programme who were not being followed up for previous cytological abnormalities. DATA COLLECTION AND ANALYSIS We completed a 2 x 2 table with the number of true positives (TP), false positives (FP), true negatives (TN), and false negatives for each screening test (HPV test and cytology) used in each study. We calculated the absolute and relative sensitivities and the specificities of the tests for the detection of CIN 2+ and CIN 3+ at various thresholds and computed sensitivity (TP/(TP + TN) and specificity (TN/ (TN + FP) for each test separately. Relative sensitivity and specificity of one test compared to another test were defined as sensitivity of test-1 over sensitivity of test-2 and specificity of test-1 over specificity of test-2, respectively. To assess bias in the studies, we used the Quality Assessment of Diagnostic test Accuracy Studies (QUADAS) tool. We used a bivariate random-effects model for computing pooled accuracy estimates. This model takes into account the within- and between-study variability and the intrinsic correlation between sensitivity and specificity. MAIN RESULTS We included a total of 40 studies in the review, with more than 140,000 women aged between 20 and 70 years old. Many studies were at low risk of bias. There were a sufficient number of included studies with adequate methodology to perform the following test comparisons: hybrid capture 2 (HC2) (1 pg/mL threshold) versus conventional cytology (CC) (atypical squamous cells of undetermined significance (ASCUS)+ and low-grade squamous intraepithelial lesions (LSIL)+ thresholds) or liquid-based cytology (LBC) (ASCUS+ and LSIL+ thresholds), other high-risk HPV tests versus conventional cytology (ASCUS+ and LSIL+ thresholds) or LBC (ASCUS+ and LSIL+ thresholds). For CIN 2+, pooled sensitivity estimates for HC2, CC and LBC (ASCUS+) were 89.9%, 62.5% and 72.9%, respectively, and pooled specificity estimates were 89.9%, 96.6%, and 90.3%, respectively. The results did not differ by age of women (less than or greater than 30 years old), or in studies with verification bias. Accuracy of HC2 was, however, greater in European countries compared to other countries. The results for the sensitivity of the tests were heterogeneous ranging from 52% to 94% for LBC, and 61% to 100% for HC2. Overall, the quality of the evidence for the sensitivity of the tests was moderate, and high for the specificity.The relative sensitivity of HC2 versus CC for CIN 2+ was 1.52 (95% CI: 1.24 to 1.86) and the relative specificity 0.94 (95% CI: 0.92 to 0.96), and versus LBC for CIN 2+ was 1.18 (95% CI: 1.10 to 1.26) and the relative specificity 0.96 (95% CI: 0.95 to 0.97). The relative sensitivity of HC2 versus CC for CIN 3+ was 1.46 (95% CI: 1.12 to 1.91) and the relative specificity 0.95 (95% CI: 0.93 to 0.97). The relative sensitivity of HC2 versus LBC for CIN 3+ was 1.17 (95% CI: 1.07 to 1.28) and the relative specificity 0.96 (95% CI: 0.95 to 0.97). AUTHORS' CONCLUSIONS Whilst HPV tests are less likely to miss cases of CIN 2+ and CIN 3+, these tests do lead to more unnecessary referrals. However, a negative HPV test is more reassuring than a negative cytological test, as the cytological test has a greater chance of being falsely negative, which could lead to delays in receiving the appropriate treatment. Evidence from prospective longitudinal studies is needed to establish the relative clinical implications of these tests.

Abstract
OBJECTIVE To describe the effect of antiretroviral therapy (ART) and HIV-related factors on high-risk human papillomavirus (HR-HPV) and high-grade cervical intraepithelial neoplasia lesions (CIN2+) among women living with HIV/AIDS (WLHA) in sub-Saharan Africa. DESIGN Prospective cohort of WLHA in Ouagadougou, Burkina Faso (BF) and Johannesburg, South Africa (SA). Recruitment was stratified by ART status. METHODS At baseline and endline (median 16 months), cervical samples, and biopsies were analyzed for HPV genotyping (InnoLiPA) and by histology. Logistic regression was used to estimate associations of ART and HIV-related factors with HR-HPV and CIN2+ outcomes, and all results presented are adjusted for baseline CD4 cell count. RESULTS Among 1238 enrolled WLHA (BF = 615; SA = 623), HR-HPV prevalence was 59.1% in BF and 79.1% in SA. CIN2+ prevalence was 5.8% in BF and 22.5% in SA. Compared with long-duration ART users (>2 years), HR-HPV prevalence was higher among short-duration ART users [≤2 years; adjusted prevalence ratio (aPR) = 1.24, 95% confidence interval (CI) 1.04-1.47] in BF, and CIN2+ prevalence was higher among short-duration ART users [adjusted odds ratio (aOR) = 1.99, 95% CI 1.12-3.54) and ART-naive participants (aOR = 1.87, 95% CI 1.11-3.17) in SA. Among 963 (77.8%) women seen at endline, HR-HPV persistence was 41.1% in BF and 30.2% in SA; CIN2+ incidence over 16-months was 1.2% in BF and 5.8% in SA. HR-HPV persistence was associated with being ART-naive in BF (aPR = 1.89, 95% CI 1.26-2.83), and with short-duration ART use (aPR = 1.78, 95% CI 1.11-2.86) and HIV-1 plasma viral load at least 1000 copies/ml (aPR = 2.87, 95% CI 1.63-5.05) in SA. CIN2+ incidence was reduced among women on ART in SA (aOR = 0.39, 95% CI 0.15-1.01). CONCLUSION Prolonged and effective ART is important in controlling HR-HPV and the development of CIN2+.

Abstract
Human papillomavirus is a virus that is distributed worldwide, and persistent infection with high-risk genotypes (HR-HPV) is considered the most important factor for the development of squamous cell cervical carcinoma (SCC). However, by itself, it is not sufficient, and other factors may contribute to the onset and progression of lesions. For example, infection with other sexually transmitted diseases such as human immunodeficiency virus (HIV) may be a factor. Previous studies have shown the relationship between HPV infection and SCC development among HIV-infected women in many regions of the world, with great emphasis on low- and middle- income countries (LMICs). Brazil is considered a LMIC and has great disparities across different regions. The purpose of this review was to highlight the current knowledge about HPV infection and cervical abnormalities in HIV+ women in Brazil because this country is an ideal setting to evaluate HIV impact on SCC development and serves as model of LMICs and low-resource settings.

Abstract
HPV is associated with cervical cancer and plays a crucial role in tumor formation. Apoptosis is regulated by different pathways involving genes that either promote (BCL2 gene) or inhibit (BAX gene) cell death. Our goal was to determine whether the BCL2-938C>A (rs2279115) and BAX-248G>A (rs4645878) single nucleotide polymorphisms (SNPs) are associated with squamous intraepithelial neoplasia (SIL) risk, and whether their phenotypic expression was impaired in these lesions. Two hundred and thirty-one cases showing SIL were classified as low SIL (LSIL, n = 101) or high SIL (HSIL, n = 130), and control subjects (n = 266) with no gynecologically proven SIL were recruited. No statistical difference in the genotype and allelic frequency of the BCL-2-938C>A polymorphism was observed among the groups. BCL2-938C/A and A/A homozygotes carriers had higher distribution of BCL-2-expressing cells in stroma in the SIL group. BCL2 mRNA-expression was not correlated with BCL2-938C>A SNPs in both groups. We did find a strong association of the BAX GG genotype and risk for SIL. No difference was observed between LSIL and HSIL groups. In BAX-248G/A and A/A homozygote carriers, the number of BAX-expressing cells was lower the epithelium area in SIL. However, mRNA expression was higher in SIL patients than in the control group. In conclusion, our data provide evidence that allele G carriers in the BAX-248G>A promoter SNP may influence the development of SIL. However, this genotype does not influence the SIL outcome. Additionally, we suggest a possible role of HPV infection in the inhibition of the expression of BAX protein, decreasing cell death, and favoring cervical carcinogenesis.

Abstract
Background In Brazil, the rate of cervical cancer remains high despite the availability of screening programs. With ongoing vaccine development and implementation, information on the prevalence of specific HPV types is needed, particularly among high-risk populations, such as HIV-infected women. Methods We performed a study of HIV-infected women in Rio de Janeiro, Brazil, who underwent cervical HPV genotype testing between 2005-2013. We examined the prevalence of high-risk HPV types and the patterns of high-risk HPV type clustering. Using logarithmic binomial regression, we estimated the risk of abnormal cytology by HPV genotype result. Results Of the 562 women included, 498 (89 %) had at least one HPV type detected. 364 women (65 %) had at least one high-risk HPV type detected and 181 (32 %) had more than one high-risk type detected. HPV 58 was the most frequent HPV type detected overall (prevalence 19.8 % [95 % confidence interval 16.4–23.1]), followed by HPV 53 (prevalence 15.5 % [12.5–18.5]) and HPV 16 (prevalence 13 % [10.2–15.8]). Women infected with more than one high-risk HPV type were younger, had lower CD4+ lymphocyte counts, and were more likely to be infected with HPV 16 or 18. In adjusted analyses, presence of more than one high-risk HPV type was associated with a two-fold increased risk of abnormal cytology after adjusting for presence of individual high-risk type, age, and CD4+ lymphocyte count (adjusted prevalence ratios 1.88–2.07, all p <0.001). No single high-risk HPV type was statistically associated with abnormal cytology after adjusting for the presence of more than one high-risk HPV type. Conclusions In the largest study of cervical HPV genotypes among HIV-infected women in Latin America, infection by high-risk HPV types other than 16 or 18 and infection by more than one high-risk HPV types were common. Infection by more than one high-risk type was more strongly associated with abnormal cervical cytology than any individual high-risk HPV type, highlighting the need for multi-valent HPV vaccines.

Abstract
Background The prevalence of High-Risk Human papilloma virus (HR-HPV), a necessary cause of invasive cervical cancer (ICC) is relatively high in HIV infected women. Gaps exist in our knowledge of the optimal approaches for managing women who have HR-HPV with normal cervical cytology (NCC) particularly in settings of HIV infection. Methods Between May 2012 and June 2013 we conducted a colposcopic assessment of HIV-infected women with prior (NCC) and known HR-HPV status to compare cervical abnormalities in women with and without HR-HPV. Colposcopic examinations were done at the Operation Stop Cervical Cancer (OSCC) unit of the Jos University Teaching Hospital (JUTH), Jos, Nigeria. Abnormal colposcopic finding (ACF) was defined as areas of aceto-white epithelium involving the squamo-coulumnar junction, areas of punctation, mosaic pattern or atypical vessels. We compared proportions of ACF as well as histologic grades of cervical intra-epithelial neoplasia (CIN) in women with or without HR-HPV. Statistical analysis was done on STATA. Results We conducted colposcopic examinations in 78 out of 89 (86.5%) eligible women. The mean age of the cohort was 32.4 years (SD ±4.6) with a median 32 years (IQR 29–36). After a mean follow up time of 20.1 months from the initial cervical pap cytology and HR-HPV testing, we found 12 of 78 (15.4%) women with ACF. The odds for an ACF was statistically higher [OR = 4.0 (95% CI: 1.1-14.7)] in women with HR-HPV compared to those without. Of the twelve women with ACF, subsequent histologic examination of colposcopically directed cervical biopsies confirmed CIN 1 in 4 cases (33.3%), CIN 2 in 1 case (8.3%), CIN 3 in 2 cases (16.7%), carcinoma-in-situ (CIS) in 2 cases (16.7%), and normal cervix in 3 (25.0%). Overall, the proportion of women detected with any grade of CIN was 11.5% (9/78) and 6.4% (5/78) were CIN 2 or greater lesion (CIN2+). Conclusion HIV-infected women with NCC and HR-HPV had a four-fold higher likelihood for an ACF. The practice of early colposcopic examination of HIV-infected women with prior NCC and HR-HPV may increase early detection of higher grade CIN and CIS cancer stages in our setting.

Abstract
Background Facing the dual burden of invasive cervical cancer and HIV in sub-Saharan Africa, the identification of preventable determinants of Cervical Intraepithelial Neoplasia (CIN) in HIV-infected women is of paramount importance. Methods A cervical cancer screening based on visual inspection methods was proposed to HIV-infected women in care in Abidjan, Côte d'Ivoire. Positively screened women were referred for a colposcopy to a gynaecologist who performed directed biopsies. Results Of the 2,998 HIV-infected women enrolled, 132 (4.4%) CIN of any grade (CIN+) were identified. Women had been followed-up for a median duration of three years [IQR: 1–5] and 76% were on antiretroviral treatment (ART). Their median most recent CD4 count was 452 [IQR: 301–621] cells/mm3. In multivariate analysis, CIN+ was associated with a most recent CD4 count >350 cells/mm3 (OR: 0.3; 95% CI: 0.2–0.6) or ≥200–350 cells/mm3 (OR 0.6; 95% CI 0.4–1.0) (Ref: <200 cells/mm3 CD4) (p<10−4). Conclusions The presence of CIN+ is less common among HIV-infected women with limited or no immune deficiency. Despite the potential impact of immunological recovery on the reduction of premalignant cervical lesions through the use of ART, cervical cancer prevention, including screening and vaccination remains a priority in West Africa while ART is rolled-out.

Abstract
OBJECTIVES Sub-Saharan Africa is at the epicentre of the human immunodeficiency virus (HIV) epidemic and has the highest incidence of invasive cervical cancer (ICC) in the world. Access to highly active antiretroviral treatment (HAART) in South Africa is still limited and provided only to nonpregnant women with a CD4+ T-cell count <200 μg/L. We evaluated the relative distribution of cervical preinvasive and invasive neoplasia among HIV-infected (treated or not) and uninfected women in the Limpopo Province of South Africa. METHODS We compared the consecutive biopsy-diagnosed cervical pathology of 1,023 HIV-infected and 1,023 uninfected women. We investigated the influence of the CD4+ T-cell count and of HAART on the relative distribution of cervical pathology. RESULTS There was a significantly higher proportion of cervical intraepithelial neoplasia (CIN)1 (P = 0.012) and 2 (P = 0.01) but a lower proportion of ICC (P = 0.015) among HIV-infected women. Patients on HAART had less CIN1 (P = 0.018), 2 (P = 0.18) and ICC (P = 0.019) that their untreated counterparts. The mean CD4 count was similar regardless of cervical lesions and HAART or no treatment. CONCLUSION Our data support the concept that HIV-infected women exhibit a higher rate of high-grade preinvasive lesions than uninfected controls. However, they have a significantly lower rate of ICC as compared with uninfected counterparts. The inclusion of ICC among acquired immune deficiency syndrome-defining illnesses is questionable.

Abstract
People living with HIV are at an increased risk of acquiring HPV and of developing evolutive cervical cancers (women) and penile and anal cancers (men). Low-cost screening-visual inspection with acetic acid, HPV DNA diagnostics and primary care level treatment, cryotherapy for cervical intraepithelial neoplasia (CIN 2), and primary prevention through HPV vaccination of girls aged 9-13 years-makes the goal of eliminating cervical cancer possible in the long term. Integration of cervical cancer screening and treatment into a sexual and reproductive health service package raises programmatic questions and calls for a continuum of care. The latter is only possible when adequate cytopathology skills and treatment for advanced cancer conditions are available. The present paper highlights the role of member societies of the International Federation of Gynecology and Obstetrics (FIGO) in developing the base for an integrated package that responds to women's sexual and reproductive health needs.

Abstract
OBJECTIVE HIV(+) pregnant women are at a higher risk of HPV infection and development of cervical cancer. Our objectives were to assess the prevalence and HPV types in HIV(+) pregnant women and to identify risk factors for HPV infection and cytological abnormalities. METHODS Cervicovaginal smears were collected during pregnancy from 140 women. Partial HPV L1 gene and the exon 4 of the human TP53 gene (containing codon 72) were PCR-amplified and sequenced. Amplified products indicating multiple HPV infection were further cloned and sequenced. The association of demographic, obstetric and HIV-related clinical variables with HPV infection and cervical lesions was tested by univariate analyses, and significant factors were subsequently tested by logistic regression multivariate analysis. RESULTS HPV DNA tested positive for 118 patients and HPV types were identified in 104 samples. Twenty-eight different types were found, HPV-16 and HPV-58 being the most prevalent. High-risk types were present in 79.8% of samples and multiple infections in 16.3%. Abnormal cervical smears were found in 44 patients (31.4%). Absolute CD4(+) T-cell counts below 350 were associated with HPV infection. Younger age was associated with cervical abnormalities and higher CD4(+) T-cell count was an apparent protective factor. CONCLUSIONS We found a high prevalence of HPV infection and high-risk types in this cohort. Our results highlighted the relevance of immune system integrity rather than TP53 variants for protecting this highly vulnerable population to HPV infection and carcinogenesis.

Abstract
OBJECTIVES To determine the prevalence of HPV and cervical neoplasia among HIV-infected women in southwestern China. METHODS Cervical cytology, HPV detection by Hybrid Capture-2™ assay, and diagnostic colposcopy were followed by cervical biopsy if indicated. Logistic regression analysis was used to analyze associations between HPV co-infection and cervical intraepithelial neoplasia (CIN), and HIV-related clinical and laboratory parameters. RESULTS Colposcopic-histopathologically proven CIN2+ lesions were present in 7/83 (8.4%) HIV-infected women. Nearly half (41/83, 43%) were co-infected with carcinogenic HPV genotypes. HPV co-infection was higher in women with colposcopic-histopathologically proven CIN2+ lesions than women with <CIN1 after adjusting for age (OR: 8.3, 95% CI: 0.9, 73.4). Women with CD4+ cell counts less than 350 cells/μL had higher CIN2+ prevalence after adjusting for current ART status and age (adjusted OR: 6.3, 95% CI: 1.1, 36.5). CONCLUSIONS HIV/AIDS care and treatment programs should integrate effective cervical cancer prevention services to mitigate the risk of invasive cervical cancer among HIV-infected women in China.
