Abstract
Introduction cervical intraepithelial neoplasia the precursor of cervical cancer occurs with increased frequency in women infected with human immunodeficiency virus (HIV). This study aimed at determining the prevalence and correlates of abnormal cervical cytology among HIV-infected women and compare to the uninfected women. Methods a cross-sectional study conducted among HIV-infected and uninfected women enrolled in a HIV study in Central Kenya. All women had baseline Pap smear examination assessed using Bethesda system. Bivariate and multivariate logistic regression methods were employed to assess the correlates of cervical squamous epithelial lesions (CSIL). Results a total 480 women had an acceptable baseline smear, 373 (78%) were HIV-infected. Median age was 30.2 years [IQR 25.4-35.5]. Overall prevalence of CSIL was 37% (176/480) with the prevalence of low grade squamous intraepithelial lesion (LSIL), atypical squamous cells undetermined significance (ASCUS), high grade squamous intraepithelial lesions (HSIL) and atypical glandular cells (AGC) were 17%, 14%, 4% and 2% respectively. HIV-infected women had a higher prevalence of CSIL at 42% as compared to HIV-uninfected women at 19%. HIV infection was the predictor associated with development of CSIL at multivariate analysis and specifically, HIV-infected women were 3 times (AOR 3.1, 95% CI: 1.8 - 5.4, p<0.005) more likely to have CSIL than HIV-uninfected women. The age 35 - 44 years was protective to developing CSIL (AOR 0.45, 95% CI: 0.24 - 0.87, p=0.018). Conclusion cervical squamous epithelial lesions is a major problem among Kenyan women. HIV infection confers a higher risk to development of CSIL. Cervical cancer screening should be an established practice in HIV programs.

Abstract
Human papillomavirus (HPV) is the most common sexually transmitted infection in the world. Several studies have shown a higher prevalence of HPV infection in HIV-infected women. The aim of this study was to determine the prevalence and the genotype diversity of HPV infection in HIV-infected women. From April 2010 to December 2012 cervical specimens were collected from 169 HIV-infected women who screening for cervical cancer at Reference Unit in Belém. The detection of HPV infection was performed by nested PCR and HPV type was performed using a commercial system. The prevalence of HPV infection was 63.3%. Of the 47 genotyped samples, 40.4% was found positive for high risk-HPV 16 and 12.8% for high risk-HPV 52. HPV infection was predominant in the group of women with no incidence of cytological abnormalities and more prevalent in women of reproductive age, unmarried, low education level, and who reported use condoms during sexual intercourse. It was observed an association between HPV infection and independent variables, such as condom use, multiple sexual partners, and history of sexually transmitted diseases. High-risk types of HPV infection were prevalent in our study. Infection with multiple high-risk HPV genotypes may potentiate the development of cervical cancer in HIV-infected women.

Abstract
BACKGROUND Anal cancer rates have increased, particularly in human immunodeficiency virus (HIV)-infected (HIV+) women. We assessed factors associated with anal precancer in HIV+ and at-risk HIV-negative women from the Atlanta Women's Interagency HIV Study cohort. METHODS All participants underwent high-resolution anoscopy and anal cytology and had anal and cervical samples collected. Specimens were tested for 37 human papillomavirus (HPV) types and for FAM19A4 and microRNA124-2 promoter methylation. Binary logistic regression and multivariate analysis were conducted with histologic anal high-grade squamous intraepithelial lesion (A-HSIL) as the dependent variable. RESULTS Seventy-five women were enrolled: 52 (69%) were HIV+ with three-fourths having undetectable viral load; 64 (86%) were black; mean age was 49 ± 8 years. Forty-nine (65%) anal cytology samples were abnormal, and 38 (51%) of anal samples were positive for at least 1 of 13 high-risk HPV (hrHPV) types. Thirteen (18%) anal biopsies identified A-HSIL. Hypermethylation of FAM19A4 and/or microRNA124-2 was found in 69 (95%) anal samples and 19 (26%) cervical samples. In multivariate analyses, the odds of having A-HSIL were >6 times higher in women with anal hrHPV (adjusted odds ratio [aOR], 6.08 [95% confidence interval {CI}, 1.27-29.18], P = .02) and with positive cervical methylation (aOR, 6.49 [95% CI, 1.66-25.35], P = .007), but not significantly higher in women with positive anal methylation. CONCLUSIONS Anal hrHPV and promoter hypermethylation in the cervix show promise as biomarkers for anal cancer screening in HIV+ and at-risk HIV-negative women. Greater understanding of gene silencing by promoter hypermethylation in anal carcinogenesis is needed.

Abstract
BACKGROUND People living with HIV (PLHIV) are at a high risk of developing HPV-related cancers. HPV-related malignancies occur frequently and/or are high among PLHIV, with cervical cancer as a designated AIDS-defining condition. We aimed to explore the evidence on the interplay of HIV and HPV-related cancers in sub-Saharan Africa (SSA). METHODS The scoping review was guided by Arksey and O'Malley's framework. We searched for literature from the following databases: PubMed; World Health Organization (WHO) Library; Science Direct; Google Scholar and EBSCOhost (Academic search complete, Health Source: Nursing/Academic Edition, CINAHL). Studies reporting on evidence HIV and HPV-related cancers interplay in SSA were eligible for inclusion in this review. The Mixed Methods Appraisal Tool (MMAT) tool was used to assess the risk of bias of the included studies. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) was used for reporting the search results. Thematic analysis used to reveal the emerging themes from the included studies. RESULTS A total of 74 potentially eligible articles were screened. Of these, nine (7 reviews, 1 transversal case controls, and 1 quantitative study) were eligible for data extraction. The studies reported about a total of 16,351 participants in different settings. The nine included studies showed evidence of cervical cancer among HIV-infected women and distribution of HPV infection and cervical abnormalities among HIV-positive individuals. In the four studies generalizing about HIV and anal cancer, only one reported about HPV. Two studies generally reported about HIV and head and neck cancers and one reported about interaction of HIV with vaginal cancer, vulvar cancer, and penile cancer, respectively. CONCLUSION HIV positivity is associated with increased prevalence of HPV infection on different anatomic sites, which will result in increased burden of HPV-related cancers among PLHIV. Furthermore, primary studies with robust study designs aimed at investigating the risk developing HPV-related cancers among PLHIV are recommended. Systematic review registration: PROSPERO CRD42017062403.

Int J Gynecol Cancer 2020; 30:772-776. [PMID: 32156714 DOI: 10.1136/ijgc-2019-000909] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2019] [Revised: 10/24/2019] [Accepted: 10/31/2019] [Indexed: 11/03/2022] Open
Abstract
BACKGROUND Invasive cervical carcinoma is associated with a human immunodeficiency virus (HIV) prevalence of >0.1%, and screening is recommended and cost-effective for cancer populations exceeding this threshold. HIV status is also prognostic for cancer-specific survival, but compliance with HIV screening is poor in the USA and abroad. OBJECTIVES This study aims to describe HIV screening practices in a US comprehensive cancer center. To guide quality improvement, we identify characteristics which may predict compliance with screening. STUDY DESIGN Women treated for invasive cervical cancer from January 2007 to December 2017 were identified by local cancer registry and billing data. We assessed age, race, ethnicity, insurance status, histology, stage, pregnancy, drug use, and HIV testing status. Univariate logistical regression was performed to assess predictors of completed HIV screening. RESULTS Of 492 eligible women, the cumulative screening rate was 7.6%. Race, ethnicity, histology, and funding source were not predictive of screening. Every 5 year increase in age was associated with a lower chance of screening (OR 0.86, p=0.015), as was earlier stage at diagnosis (OR 0.43, p=0.017). Pregnancy during, or antecedent to, invasive cervical cancer diagnosis was significantly more predictive of screening compliance (OR 10.57, p=0.0007). Only 8/492 (1.6%) women in the cohort were active or former drug users, but within this group HIV screening was performed more frequently (OR 22.7, p<0.0001). CONCLUSION Despite US and international recommendations for HIV screening in AIDS-defining cancers, compliance remains low. In our centers, factors including earlier age, advanced stage, active pregnancy at diagnosis, and any drug use history were predictive of greater compliance with screening. These data will inform a tailored intervention to improve compliance with HIV screening in our population.

Abstract
BACKGROUND Human papillomaviruses are the most important causative agents for invasive cervical cancer development. HPV type-specific vaccination and HPV cervical cancer screening methods are being widely recommended to control the disease but the epidemiology of the circulating HPV types may vary locally. The circulating HPV-strains have never been assessed in Burundi. This study determined the prevalence and genotype-specific distribution of HPV in four different strata in Burundi: HIV-infected or non-infected and women living in rural or urban areas. Implications for HPV diagnosis and vaccine implementation was discussed. METHODS Four cross-sectional surveys were conducted in Burundi (2013 in a rural area and 2016 in urban area) among HIV-infected and uninfected women living in rural and urban areas. Liquid-Based Cytology (LBC) and HPV genotyping were performed and risk factors for HPV infection and cervical pre-cancer lesions were determined using logistic regression model. RESULTS HPV prevalence was very high in urban area with significant differences between HIV-positive and negative women (p<0.0001). In fact, 45.7% of HIV-positive participants were infected with any HPV type and all were infected with at least one HR/pHR-HPV type. Among the HIV-negative participants, 13.4% were HPV-infected, of whom, only four women (2.7%) were infected with HR/pHR-HPV types. In rural area, HPV infection did not significantly differ between HIV-positive and negative women (30.0% and 31.3% respectively; p = 0.80). In urban area, multiple infections with HR/pHR-HPV types were detected in 13.9% and 2.7% among HIV-positive and negative women respectively (p<0.0001), whereas in rural area, multiple infections with HR/pHR-HPV types were detected in 4.7% and 3.3% of HIV-positive and negative women respectively (p = 0.56). The most prevalent HR/pHR-HPV types in HIV-positive women living in urban area were HPV 52, 51, 56, 18 and 16 types. In HIV-negative women living in urban area, the most prevalent HR/pHR-HPV types were HPV 66, 67, 18, 45 and 39 types. In HIV-positive women living in rural area, the most prevalent HR/pHR-HPV types were HPV 66, 16, 18 and 33 types. In HIV-negative women living in rural area, the most prevalent HR/pHR-HPV types were HPV 16, 66, 18, 35 and 45 types. Independent risk factors associated with cervical lesions were HPV and HIV infections. CONCLUSIONS There is a high burden of HR and pHR-HPV infections, in particular among HIV-infected women living in urban area. The study points out the need to introduce a comprehensive cervical cancer control programme adapted to the context. This study shows that the nonavalent vaccine covers most of the HR/pHR-HPV infections in rural and urban areas among HIV-infected and uninfected women.

van Schalkwyk C, Moodley J, Welte A, Johnson LF. Are associations between HIV and human papillomavirus transmission due to behavioural confounding or biological effects? Sex Transm Infect 2018; 95:122-128.

Abstract
OBJECTIVES Cohort studies have shown significant increased risk of HIV acquisition following human papillomavirus (HPV) detection and increased risk of new HPV detection in individuals with HIV infection, after adjusting for behavioural risk factors. This study uses an individual-based model to assess whether confounding sexual behaviour factors and network level effects can explain these associations between HIV and HPV infection status, without biological interactions. METHODS The model simulates infection with 13 oncogenic HPV types and HIV. It allows for different relationship types, with heterogeneity in probabilities of concurrency and rates of partner change. No effect of prevalent HPV infection on HIV acquisition is assumed and vice versa. The model is calibrated to South African HIV and type-specific HPV prevalence data using a Bayesian approach. The model is used to simulate cohorts with quarterly HIV and HPV testing from 2000 to 2002. These simulated data are analysed using proportional hazard models. RESULTS The mean of the unadjusted HRs of HIV acquisition following detection of an oncogenic HPV type calculated for each simulated cohort is 2.6 (95% CI 2.2 to 3.1). The mean of the unadjusted HRs for the effect of HIV on newly detected HPV is 2.5 (95% CI 2.2 to 2.8). Simulated associations between HIV and HPV infection status are similar to corresponding empirical estimates. In sensitivity analyses in which HIV and HPV were assumed to increase each other's transmission risk, simulated associations were stronger but not inconsistent with empirical estimates. CONCLUSIONS Although we cannot rule out the possibility that associations between HIV and HPV transmission may be due in part to biological interactions, these results suggest that observed associations could be explained entirely by residual confounding by behavioural factors and network-level effects that observational studies cannot account for.

Abstract
INTRODUCTION Observational studies suggest HIV and human papillomavirus (HPV) infections may have multiple interactions. We reviewed the strength of the evidence for the influence of HIV on HPV acquisition and clearance, and the influence of HPV on HIV acquisition. METHODS We performed meta-analytic systematic reviews of longitudinal studies of HPV incidence and clearance rate by HIV status (review 1) and of HIV incidence by HPV status (review 2). We pooled relative risk (RR) estimates across studies using random-effect models. I2 statistics and subgroup analyses were used to quantify heterogeneity across estimates and explore the influence of participant and study characteristics including study quality. Publication bias was examined quantitatively with funnel plots and subgroup analysis, as well as qualitatively. RESULTS AND DISCUSSION In review 1, 37 publications (25 independent studies) were included in the meta-analysis. HPV incidence (pooled RR = 1.55, 95% CI: 1.29 to 1.88; heterosexual males: pooled RR = 1.95, 95% CI: 1.62, 2.34; females: pooled RR = 1.63, 95% CI: 1.26 to 2.11; men who have sex with men: pooled RR = 1.36, 95% CI: 1.01 to 1.82) and high-risk HPV incidence (pooled RR = 2.20, 95% CI: 1.90 to 2.54) was approximately doubled among people living with HIV (PLHIV) whereas HPV clearance rate (pooled RR = 0.53, 95% CI: 0.42 to 0.67) was approximately halved. In review 2, 14 publications (11 independent studies) were included in the meta-analysis. HIV incidence was almost doubled (pooled RR = 1.91, 95% CI 1.38 to 2.65) in the presence of prevalent HPV infection. There was more evidence of publication bias in review 2, and somewhat greater risk of confounding in studies included in review 1. There was some evidence that adjustment for key confounders strengthened the associations for review 2. Misclassification bias by HIV/HPV exposure status could also have biased estimates toward the null. CONCLUSIONS These results provide evidence for synergistic HIV and HPV interactions of clinical and public health relevance. HPV vaccination may directly benefit PLHIV, and help control both HPV and HIV at the population level in high prevalence settings. Our estimates of association are useful for mathematical modelling. Although observational studies can never perfectly control for residual confounding, the evidence presented here lends further support for the presence of biological interactions between HIV and HPV that have a strong plausibility.

Abstract
Background The risk of anal cancer due to high-risk human papillomavirus (HR-HPV) is higher in women living with human immunodeficiency virus (HIV) than in the general population. We present findings of cervical and anal HPV and cytologic tests at baseline in the EVVA cohort study and HPV persistence data 6 months after baseline. Methods Semiannual visits included questionnaires, chart reviews, cervical/anal cytologic and cervical/anal HPV testing for 2 years. Genotyping for 36 HPV genotypes was performed using the Roche Linear Array HPV genotyping test. Results A total of 151 women living with HIV were recruited. At baseline, 75% had anal HPV, 51% had anal HR-HPV, 50% had cervical HPV, and 29% had cervical HR-HPV. Anal HPV-16 and HPV-51 were more frequent in women born in Canada (31% and 29%, respectively, compared with ≤16% for other women). Most anal HR-HPV types detected at 6 months (57%-93%) were persistent from baseline. Findings of anal cytologic tests were abnormal for 37% of women. Conclusions Anal HPV is highly prevalent in women living with HIV, and type distribution varies by place of birth. High-resolution anoscopy was indicated in more than one third of results. As anal cancer is potentially preventable, these important findings need to be considered when selecting the best approach for anal cancer screening programs.

A Comparison of the Natural History of HPV Infection and Cervical Abnormalities among HIV-Positive and HIV-Negative Women in Senegal, Africa. Cancer Epidemiol Biomarkers Prev 2017; 26:886-894. [PMID: 28515108 DOI: 10.1158/1055-9965.epi-16-0700] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2016] [Revised: 01/05/2017] [Accepted: 01/18/2017] [Indexed: 11/16/2022] Open
Abstract
Background: There is evidence of an interaction between HIV and human papillomavirus (HPV) resulting in increased HPV-associated morbidity and cancer mortality among HIV-positive women. This study aims to determine how the natural history of cervical HPV infection differs by HIV status.Methods: A total of 1,320 women (47% were positive for HIV-1 and/or HIV-2) were followed for an average of two years in Senegal, West Africa between 1994 and 2010. Cytology (with a sub-sample of histology) and HPV DNA testing were performed at approximately 4-month intervals yielding data from over 7,900 clinic visits. Competing risk modeling was used to estimate rates for transitioning between three clinically relevant natural history stages: Normal, HPV, and HSIL (high-grade squamous intraepithelial lesions). Among HIV-positive women, exploratory univariate analyses were conducted examining the impact of HPV type, infection with multiple HPV types, HIV type, CD4+ count, and age.Results: HIV-positive women had higher rates of progression and lower rates of regression compared with HIV-negative women (i.e., adverse transitions). HIV-positive women had a 2.55 [95% confidence interval (CI), 1.69-3.86; P < 0.0001] times higher rate of progression from HPV to HSIL than HIV-negative women (with 24-month absolute risks of 0.18 and 0.07, respectively). Among HIV-positive women, HPV-16/18 infection and CD4+ count <200/mm3 were associated with adverse transitions.Conclusions: Adverse HIV effects persist throughout HPV natural history stages.Impact: In the limited-resource setting of sub-Saharan Africa where cervical cancer screening is not widely available, the high-risk population of HIV-positive women may be ideal for targeted screening.

Abstract
BACKGROUND Human papilloma virus (HPV) is a common sexually transmitted virus which infects the cutaneous and mucosal epithelium. HPV Type 16 is one of the viruses that causes cervical cancer and immunocompromised individuals are at high risk of different co-infections. Women living with Human Immunodeficiency Virus (HIV) have greater risk to the virus due to their impaired immunity. This study aimed at determining the seroprevalence of HPV IgM (Type 16) among HIV-infected women in Ogbomoso. METHODS The blood sample of 180 consenting subjects were obtained and their sera subjected to serological assay using Enzyme Linked Immunosorbent Assay. Samples were collected over a period of 6 months (July-December 2014). RESULTS The mean age and mean CD4+ count of the subjects was 38.22 ± 0.79 years and 392.80 ± 20.98 cells/μL, respectively. Out of 180 subjects tested, 18 (10%; 95% confidence interval) were positive for HPV Type 16 IgM. HPV Type 16 IgM was highest among the age group 31-45 (61.11%), traders (38.89%), >500 CD4/μL (33.33%). The seroprevalence using logistic regression at P < 0.05 shows there is a significant difference between the age and CD4 (+) cell count. CONCLUSION The result provides evidence that HPV Type 16 is present among HIV-infected women in Ogbomoso and they are susceptible to cervical cancer. This seroepidemiological survey is important for the prevention efforts such as availability of vaccine.

HIV viral suppression results in higher antibody responses in HIV-positive women vaccinated with the quadrivalent human papillomavirus vaccine. Vaccine 2016; 34:4799-806. [PMID: 27544584 DOI: 10.1016/j.vaccine.2016.08.016] [Citation(s) in RCA: 29] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2016] [Revised: 07/22/2016] [Accepted: 08/04/2016] [Indexed: 11/22/2022]
Abstract
OBJECTIVE To evaluate the immunogenicity and safety of the quadrivalent HPV (qHPV) vaccine in HIV-positive women over 24months. DESIGN Between November 2008 and December 2012, 372 women aged 15 and older were enrolled from 14 Canadian HIV outpatient clinics in an open label cohort study. The qHPV vaccine (0.5mL) was administered intramuscularly at months 0, 2 and 6. The primary study endpoint was seroconversion to any of the HPV types targeted by the qHPV vaccine. Antibody levels were measured at 0, 2, 7, 12, 18, and 24months. Adverse events were recorded throughout. RESULTS Of 372 participants enrolled, 310 (83%) received at least one dose of the qHPV vaccine and 277 (74%) received all three doses. Ninety-five percent (293/308) were seronegative for at least one vaccine type at baseline. The median age was 38years (IQR 32-45, range 15-66), 36% were white, 44% black and 13% were of Indigenous origin. Seventy-two percent of participants had a suppressed HIV viral load (VL<40c/ml) at baseline, with a median CD4 count of 510cells/mm(3) (376-695). Month 7 HPV type-specific seroconversion rates were 99.0%, 98.7%, 98.1% and 93.6% for HPV types 6, 11, 16 and 18 respectively in the per-protocol population. Participants with suppressed HIV VL at first vaccine had a 1.74-3.05fold higher peak antibody response compared to those without (p from 0.006 to <0.0001). CONCLUSIONS This study is the first to examine the qHPV vaccine in HIV-positive women out to 24months and the first to include HIV-positive women through to age 66. The qHPV vaccine was well tolerated, and highly immunogenic. As women with suppressed viral load had higher antibody responses, planning HPV vaccination to occur when persons are virologically suppressed would be optimal for maximizing immune response. Findings provide strong evidence that older HIV-positive women can still benefit from HPV vaccination. CLINICAL TRIAL REGISTRATION http://www.isrctn.com/ISRCTN33674451.

Abstract
OBJECTIVE The objective of this analysis was to assess human papillomavirus (HPV) infection persistence and incidence 7-months post-enrollment by HPV vaccine study arm (vaccine or placebo). METHODS HIV-negative, sexually active women aged 16-24 years in the Western Cape, South Africa, were enrolled in the EVRI Trial and were randomized to receive 4-valent HPV vaccine or placebo. Cervical specimens were collected at enrollment and at the 7-month visit and were genotyped for HPV. HPV prevalence, persistence, and incidence were calculated. Prevalence ratios and odds ratios were calculated to assess factors associated with a prevalent and incident HPV infection. RESULTS HPV incidence rates were marginally higher for the placebo group (n = 163) compared to the vaccine group (n = 169). A large proportion of the prevalent high-risk (HR-HPV) HPV types (49%) persisted over the 7-month period in both arms. Prevalent HR-HPV infection was significantly associated with a prevalent gonorrhea infection and detection of Herpes simplex type 2 antibodies. Incident HR-HPV infection was significantly associated with abnormal cervical cytology at enrollment and younger age. CONCLUSIONS Women living in geographic areas, such as southern Africa, at high-risk for HPV need to receive HPV vaccination at a very young age to maximally prevent infection and subsequent disease.

Abstract
Objective Female sex workers (FSWs) are at an increased risk of human immunodeficiency virus (HIV) as well as human papillomavirus (HPV) infections and thus have an increased risk of cervical intraepithelial neoplasia (CIN) and cervical cancer. We evaluated the feasibility of “screen and treat approach” for cervical cancer prevention and the performance of different screening tests among FSWs. Methods Women were screened using cytology, VIA (visual inspection with acetic acid), and VILI (visual inspection with Lugol’s iodine) and underwent colposcopy, biopsy, and immediate treatment using cold coagulation, if indicated, at the same visit. Results We screened 300 FSWs of whom 200 (66.67%) were HIV uninfected and 100 (33.34%) were HIV infected. The overall prevalence of CIN 2–3 lesions was 4.7%. But all women with CIN 2–3 lesions were HIV infected, and thus the prevalence of CIN 2–3 lesions in HIV-infected FSWs was 14/100 (14%, 95% confidence interval: 7.2–20.8). All of them screened positive by all three screening tests. Cold coagulation was well tolerated, with no appreciable side effects. Conclusion Cervical cancer prevention by “screen and treat” approach using VIA, followed by ablative treatment, in this high-risk group of women is feasible and can be implemented through various targeted intervention programs.

Abstract
Background HIV infection leads to a decreasing immune response, thereby facilitating the appearance of other infections, one of the most important ones being HPV. However, studies are needed for determining associations between immunodeficiency caused by HIV and/or the presence of HPV during the course of cervical lesions and their degree of malignancy. This study describes the cytological findings revealed by the Papanicolaou test, laboratory characteristics and HPV molecular profile in women with and without HIV infection. Methods A total of 216 HIV-positive and 1,159 HIV-negative women were invited to participate in the study; PCR was used for the molecular detection of HPV in cervical samples. Statistical analysis (such as percentages, Chi-square test and Fisher’s exact test when applicable) determined human papillomavirus (HPV) infection frequency (single and multiple) and the distribution of six types of high-risk-HPV in women with and without HIV infection. Likewise, a logistic regression model was run to evaluate the relationship between HIV-HPV infection and different risk factors. Results An association was found between the frequency of HPV infection and infection involving 2 or more HPV types (also known as multiple HPV infection) in HIV-positive women (69.0% and 54.2%, respectively); such frequency was greater than that found in HIV-negative women (44.3% and 22.7%, respectively). Statistically significant differences were observed between both groups (p = 0.001) regarding HPV presence (both in infection and multiple HPV infection). HPV-16 was the most prevalent type in the population being studied (p = 0.001); other viral types had variable distribution in both groups (HIV-positive and HIV-negative). HPV detection was associated with <500 cell/mm3 CD4-count (p = 0.004) and higher HIV-viral-load (p = 0.001). HPV-DNA detection, <200 cell/mm3 CD4-count (p = 0.001), and higher HIV-viral-load (p = 0.001) were associated with abnormal cytological findings. Conclusions The HIV-1 positive population in this study had high multiple HPV infection prevalence. The results for this population group also suggested a greater association between HPV-DNA presence and cytological findings. HPV detection, together with low CD4 count, could represent useful tools for identifying HIV-positive women at risk of developing cervical lesions.

Abstract
OBJECTIVE HIV-positive women are known to be at high-risk of human papillomavirus (HPV) infection and its associated cervical pathology. Here, we describe the prevalence and distribution of HPV genotypes among HIV-positive and -negative women in South Africa, with and without cervical intraepithelial neoplasia (CIN). METHODS We report data on 1,371 HIV-positive women and 8,050 HIV-negative women, aged 17-65 years, recruited into three sequential studies in Cape Town, South Africa, conducted among women who had no history of cervical cancer screening recruited from the general population. All women were tested for HIV. Cervical samples were tested for high-risk HPV DNA (Hybrid Capture 2) with positive samples tested to determine the specific genotype (Line Blot). CIN status was determined based on colposcopy and biopsy. RESULTS The HPV prevalence was higher among HIV-positive women (52.4%) than among HIV-negative women (20.8%) overall and in all age groups. Younger women, aged 17-19 years, had the highest HPV prevalence regardless of HIV status. HIV-positive women were more likely to have CIN 2 or 3 than HIV-negative women. HPV 16, 35, and 58 were the most common high-risk HPV types with no major differences in the type distribution by HIV status. HPV 18 was more common in older HIV-positive women (40-65 years) with no or low grade disease, but less common in younger women (17-29 years) with CIN 2 or 3 compared to HIV-negative counterparts (p < 0.03). Infections with multiple high-risk HPV types were more common in HIV-positive than HIV-negative women, controlling for age and cervical disease status. CONCLUSION HIV-positive women were more likely to have high-risk HPV than HIV-negative women; but, among those with HPV, the distribution of HPV types was similar by HIV status. Screening strategies incorporating HPV genotyping and vaccination should be effective in preventing cervical cancer in both HIV-positive and -negative women living in sub-Saharan Africa.

Abstract
BACKGROUND High-risk (HR) HPV genotypes other than 16 and 18 have been detected in a significant proportion of immunocompromised females. We aim to evaluate the frequency of HR HPV genotypes in a population of HIV-positive Caribbean women. METHODS One hundred sixty-seven consecutive, non-pregnant, HIV-positive females ≥18 years were recruited in this study. Each participant received a vaginal examination, PAP smear, and completed a questionnaire. DNA was extracted for HPV testing in 86 patients. RESULTS Mean age was 39.1 years for women positive for HR HPV and 43.1 years for women negative for HR HPV (P value = 0.040). 78% (130/167) of the women had HR HPV infections; the prevalence of abnormal cervical cytology was 38% among women who were HR HPV-positive compared to women who were HR HPV-negative (22%). Fifty-one percent of the 86 women with available genotype carried infections with HPV 16 and/or HPV 18; genotypes of unknown risk were also frequently observed. Women who had a CD4+ count of ≤200 had 7 times increased odds of carrying HR HPV infection in comparison to women with CD4+>200. CONCLUSIONS HR HPV infections in HIV infected females may consist of more than just HPV 16 and 18, but also HPV 52 and 58. Further studies are needed to determine whether HPV 52 and 58 play a significant role in the development of cervical cytological abnormalities in HIV+ women.

Abstract
Since the introduction of highly active antiretroviral therapy (HAART), the rates of opportunistic infections have decreased markedly as has overall morbidity and mortality from HIV infection in developed countries. However, opportunistic infections remain the most important cause of death in HIV-infected people due to both late presentation of HIV infections and failure of HAART to adequately restore cell-mediated immunity in all individuals. While prophylaxis may be discontinued in patients who have responded to HAART with sustained increases of their CD4 counts above risk thresholds, for those patients who fail HAART, those who are unable to tolerate it, or whose treatments are interrupted, opportunistic-infection prophylaxis remains essential. Some HIV-associated diseases, such as anogenital human papilloma virus-induced neoplasia and hepatitis C infection, have not decreased in frequency with the advent of HAART. For these conditions, effective screening and treatment programs will be necessary to prevent ongoing morbidity. This review will provide an update on HIV-associated opportunistic infections and their prevention in the age of HAART, as well as discuss novel presentations of opportunistic illnesses, such as immune restoration syndromes.

Abstract
BACKGROUND HIV infection is associated with greater risk of precancerous lesions and cervical cancer in women. However, several factors remain unclarified regarding the association between HIV infection and HPV detection, especially among those with HIV type 2 versus type 1 infection and severely immunocompromised persons. OBJECTIVES To evaluate HPV overall and type-specific detection among HIV-infected and uninfected women in Senegal. STUDY DESIGN Detection of HPV DNA for 38 genotypes in cervical swabs using PCR-based methods was evaluated in HIV-positive (n=467) and HIV-negative (n=2139) women participating in studies in Senegal. Among HIV-1 and/or HIV-2 positive women, CD4 counts were assessed. Adjusted multivariable prevalence ratios (PR) were calculated. RESULTS The prevalence of any HPV DNA and multiple HPV types was greater among HIV-infected individuals (78.2% and 62.3%, respectively) compared with HIV-negative women (27.1% and 11.6%). This trend was also seen for HPV types 16 and 18 (13.1% and 10.9%) compared to HIV-negative women (2.2% and 1.7%). HIV-infected women with CD4 cell counts less than 200 cells/μl had a higher likelihood of any HPV detection (PRa 1.30; 95% CI 1.07-1.59), multiple HPV types (PRa 1.52; 95% CI 1.14-2.01), and HPV-16 (PRa 9.00; 95% CI 1.66-48.67), but not HPV-18 (PRa 1.20, 95% CI 0.45-3.24) compared to those with CD4 counts 500 cells/μl or above. CONCLUSION HIV-infected women, especially those most severely immunocompromised, are more likely to harbor HPV. Measures to prevent initial HPV infection and subsequent development of cervical cancer through focused screening efforts should be implemented in these high risk populations.

Abstract
Persistent high-risk human papillomavirus (HR-HPV) infection is the strongest risk factor for high-grade cervical precancer. We performed a systematic review and meta-analysis of HPV persistence patterns worldwide. Medline and ISI Web of Science were searched through January 1, 2010 for articles estimating HPV persistence or duration of detection. Descriptive and meta-regression techniques were used to summarize variability and the influence of study definitions and characteristics on duration and persistence of cervical HPV infections in women. Among 86 studies providing data on over 100,000 women, 73% defined persistence as HPV positivity at a minimum of two time points. Persistence varied notably across studies and was largely mediated by study region and HPV type, with HPV-16, 31, 33 and 52 being most persistent. Weighted median duration of any-HPV detection was 9.8 months. HR-HPV (9.3 months) persisted longer than low-risk HPV (8.4 months), and HPV-16 (12.4 months) persisted longer than HPV-18 (9.8 months). Among populations of HPV-positive women with normal cytology, the median duration of any-HPV detection was 11.5 and HR-HPV detection was 10.9 months. In conclusion, we estimated that approximately half of HPV infections persist past 6 to 12 months. Repeat HPV testing at 12-month intervals could identify women at increased risk of high-grade cervical precancer due to persistent HPV infections.

Abstract
BACKGROUND Cervical cancer is strongly linked to high-risk human papillomavirus (HR-HPV) and is typically preceded by cytological abnormalities. Less is known in patients with normal cervical cytology (NCC). We investigated the epidemiology of HR-HPV among HIV-infected women with NCC. METHODOLOGY We conducted a cross-sectional study between January and June 2011 among HIV-infected women with NCC at an adult HIV clinic in Jos, Nigeria. Cervical sampling and analysis for HR-HPV by hybrid capture (HC2) with signal amplification was done to determine presence of one or more of the following HR-HPV types: 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59 or 68. Epidemiologic factors associated with HR-HPV were determined using bivariate statistics and multivariate logistic regression. RESULTS We evaluated 103 HIV-infected women with Pap cytology. The median age of the women was 32 years (range 21-49). Ninety-seven (94.2%) had NCC. Cervical samples for HR-HPV DNA testing were available from 89/97 (91.8%) of the HIV-infected women with NCC. Of the 89 women with cervical samples for HR-HPV DNA testing, 40 (44.9%) had detectable HR-HPV by HC2 giving a HR-HPV prevalence of 44.9% (95% CI 33.9-55.5%). Age < 30 years was associated with HR-HPV (OR 2.69 [95% CI 1.05-6.91, p = 0.039]) while history of previous abortion showed an inverse association with HR-HPV (OR 0.33[95% CI 0.15-0.94, p = 0.039]). CONCLUSION The prevalence of HR-HPV is seemingly high among HIV-infected women with NCC in our clinical setting. These data provide support for further investigation of the clinical implications of positive HR-HPV among HIV-infected women with NCC report in cervical cancer prevention programs in Nigeria.

Abstract
OBJECTIVES Persistent human papillomavirus (HPV) infections can cause intraepithelial neoplasia of the lower genital tract. Immune-compromised women have higher rates for all lower genital tract intraepithelial neoplasia. We wish to study the distribution of genital intraepithelial neoplasia in women with and without an immune system. METHODS The study consisted of 343 women with an abnormal genital lesion or cervical cytology who were referred to a gynecologic oncologist. All patients underwent vulva, vaginal, cervical and anal colposcopy. Any lesion detected was biopsied. Demographic and medical data were collected. The Chi-square test was used to determine the relationship between immunosuppression status and various variables, including sites of intraepithelial neoplasia. RESULTS Immune-compromised women (N = 33) are more likely than immune-competent women (N = 310) to have intraepithelial neoplasia of the vulva (p < 0.05) and vagina (p < 0.05), but not more likely to have intraepithelial neoplasia of the anus or cervix. Immune-compromised women are more likely than immune-competent women to have multifocal intraepithelial neoplasia (p < 0.001). In addition, immune-compromised women are more likely to have higher grade disease of the vulva and vagina (p < 0.05), and no more likely to have higher grade disease on the cervix or anus than immune-competent women. CONCLUSION Women with conditions suppressing the immune system are at higher risk for HPV-related disease outside of the cervix and for worse HPV-related diseases than immune-competent women. This study highlights the need for vigilant evaluation of the complete lower genital tract in women with immune-compromised systems.

Abstract
BACKGROUND The risk of squamous intra-epithelial lesions (SIL) is higher in HIV-positive women. As these women begin to live longer due to highly active antiretroviral therapy (HAART), their risk of cervical cancer may increase. Few data exist regarding the effect of HAART on the incidence and progression of SIL in HIV-positive African women. The aim of this study was to evaluate the effect of HAART on the incidence and progression of SIL in HIV-positive women in South Africa. METHODS A prospective observational study of HIV-seropositive women was conducted over 5 years in an HIV treatment clinic in Johannesburg, South Africa. The participants consisted of 601 women on and off HAART who had repeat Pap smears greater than 6 months apart. The effect of HAART use on incidence and progression rates of SIL was determined using multivariate Poisson regression to obtain incidence rate ratios (IRRs), adjusted for age, CD4 count and other potential confounders. RESULTS Median follow-up time was 445 days (inter-quartile range 383, 671). The crude rate of incidence of any SIL was 15.9 episodes (95% confidence limit (CL) 12.7, 19.9) per 100 person-years; the crude rate of all progression of cervical dysplasia among women was 13.5 episodes (95% CL 11.3, 16.1) per 100 person-years. HAART use was associated with a robust reduction in the rate of incidence and progression of cervical lesions, adjusted IRR=0.55 (95% CL 0.37, 0.80). Sensitivity analyses confirmed this main association held for incidence and progression when they were considered separately, and that the result was not dependent on the length of HAART exposure. CONCLUSION HAART use was associated with a reduction in the rate of both incidence and progression of cervical lesions among HIV-positive women.

Abstract
INTRODUCTION HIV-positive women have an increased risk of invasive cervical cancer but cytologic screening is effective in reducing incidence. Little is known about cervical screening coverage or the prevalence of abnormal cytology among HIV-positive women in Ukraine, which has the most severe HIV epidemic in Europe. METHODS Poisson regression models were fitted to data from 1120 women enrolled at three sites of the Ukraine Cohort Study of HIV-infected Childbearing Women to investigate factors associated with receiving cervical screening as part of HIV care. All women had been diagnosed as HIV-positive before or during their most recent pregnancy. Prevalence of cervical abnormalities (high/low grade squamous intraepithelial lesions) among women who had been screened was estimated, and associated factors explored. RESULTS Overall, 30% (337/1120) of women had received a cervical screening test as part of HIV care at study enrolment (median 10 months postpartum), a third (115/334) of whom had been tested >12 months previously. In adjusted analyses, women diagnosed as HIV-positive during (vs before) their most recent pregnancy were significantly less likely to have a screening test reported, on adjusting for other potential risk factors (adjusted prevalence ratio (APR) 0.62, 95% CI 0.51-0.75 p<0.01 for 1(st)/2(nd) trimester diagnosis and APR 0.42, 95% CI 0.28-0.63 p<0.01 for 3(rd) trimester/intrapartum diagnosis). Among those with a cervical screening result reported at any time (including follow-up), 21% (68/325) had a finding of cervical abnormality. In adjusted analyses, Herpes simplex virus 2 seropositivity and a recent diagnosis of bacterial vaginosis were associated with an increased risk of abnormal cervical cytology (APR 1.83 95% CI 1.07-3.11 and APR 3.49 95% CI 2.11-5.76 respectively). CONCLUSIONS In this high risk population, cervical screening coverage as part of HIV care was low and could be improved by an organised cervical screening programme for HIV-positive women. Bacterial vaginosis testing and treatment may reduce vulnerability to cervical abnormalities.

Abstract
Human papillomavirus (HPV) is detected in nearly all cervical cancers and approximately half of vaginal cancers. However, vaginal cancer is an order of magnitude less common than cervical cancer, not only in the general population but also among women with HIV/AIDS. It is interesting therefore that recent studies found that HPV was common in both normal vaginal and cervical tissue, with higher prevalence of nononcogenic HPV types in the vagina. In our investigation, we prospectively examined HPV infection in 86 HIV-positive and 17 HIV-negative women who underwent hysterectomy during follow-up in a longitudinal cohort. Cervicovaginal lavage specimens were obtained semi-annually and tested for HPV DNA by polymerase chain reaction. To address possible selection biases associated with having a hysterectomy, subjects acted as their own comparison group--before versus after hysterectomy. The average HPV prevalence was higher in HIV-positive than HIV-negative women both before (59% vs. 12%; p < 0.001) and after hysterectomy (56% vs. 6%; p < 0.001). Multivariate random effects models (within-individual comparisons) demonstrated significantly lower HPV prevalence [odds ratio (OR) = 0.71; 95% confidence interval (CI) = 0.59-0.85) after hysterectomy. The association of HPV prevalence with hysterectomy was similar among HIV-positive and HIV-negative women. However, hysterectomy had greater effects on oncogenic (OR = 0.48; 95% CI = 0.35-0.66) than nononcogenic HPV types (OR = 0.89; 95% CI = 0.71-1.11; P(interaction) = 0.002). Overall, we observed greater reductions in oncogenic than nononcogenic HPV prevalence after hysterectomy. If correct, these data could suggest that oncogenic HPV have greater tropism for cervical compared to vaginal epithelium, consistent with the lower incidence of vaginal than cervical cancer.

Abstract
BACKGROUND Individuals who acquire human immunodeficiency virus (HIV) may experience an immediate disruption of genital tract immunity, altering the ability to mount a local and effective immune response. This study examined the impact of early HIV infection on new detection of human papillomavirus (HPV). METHODS One hundred fifty-five Zimbabwean women with observation periods before and after HIV acquisition and 486 HIV-uninfected women were selected from a cohort study evaluating hormonal contraceptive use and risk of HIV acquisition. Study visits occurred at 3-month intervals. Cervical swab samples available from up to 6 months before, at, and up to 6 months after the visit when HIV was first detected were typed for 37 HPV genotypes or subtypes. RESULTS We observed ∼5-fold higher odds of multiple (≥2) new HPV detections only after HIV acquisition, relative to HIV-negative women after adjusting for sexual behavior and concurrent genital tract infections. We also observed ∼2.5-fold higher odds of single new HPV detections at visits before and after HIV acquisition, relative to HIV-uninfected women in multivariable models. CONCLUSIONS These findings suggest that HIV infection has an immediate impact on genital tract immunity, as evidenced by the high risk of multiple new HPV detections immediately after HIV acquisition.

Abstract
Given the causal relationship between specific types of HPV with cervical cancer and precursor lesions, it is important to identify the viral type involved. The aim of this study is to access the prevalence of HPV types in HIV seropositive and seronegative women. Accordingly, 77 HPV positive cervical samples were obtained from 284 women (seropositive (n=112) and seronegative (n=172) for HIV) who attended a Sexually Transmitted Infection clinic, in Vitoria, Southeastern Brazil. Viral DNA was amplified by PCR using MY09/MY11 degenerated primers and the genotyping was performed by Restriction Fragment Length Polymorphism. Seventy five out of the 77 HPV samples were genotyped: 6, 11, 13, 16, 18, 26, 31, 31b, 32, 33, 34, 35, 52, 53, 55, 56, 58, 59, 61, 62, 64, 66, 71, 81, 83, 84. The most prevalent type was HPV16 followed by HPV types 6, 11 and 53. Fifty five percent and 45% belonged to high and low risk types, respectively. High risk types corresponded to 59% and 54.5% of the HPV detected in HIV seronegative and seropositive women, respectively. The uncommon HPV 13 type in cervical samples was also observed in this study. The oncogenic types were more common in the HIV seronegative samples and the number of cases with multiple infections was similar for the two groups. HPV typing is not only important clinically for the establishment of monitoring and treatment of a patient, it also provides knowledge of the viral types circulating in a population, which is of interest in the development of prevention and treatment programs for this disease.

Abstract
Exfoliative and aspiration cytologies play a major role in the management of patients with human immunodeficiency virus infection. Common cytology samples include cervicovaginal and anal Papanicolaou tests, fine needle aspirations, respiratory specimens, body fluids, Tzanck preparations, and touch preparations from brain specimens. While the cytopathologists need to be aware of specific infections and neoplasms likely to be encountered in this setting, they should be aware of the current shift in the pattern of human immunodeficiency virus-related diseases, as human immunodeficiency virus patients are living longer with highly active antiretroviral therapy and suffering fewer opportunistic infections with better antimicrobial prophylaxis. There is a rise in nonhuman immunodeficiency virus-defining cancers (e.g., anal cancer, Hodgkin's lymphoma) and entities (e.g., gynecomastia) from drug-related side effects. Given that fine needle aspiration is a valuable, noninvasive, and cost-effective tool, it is frequently employed in the evaluation and diagnosis of human immunodeficiency virus-related diseases. Anal Papanicolaou tests are also increasing as a result of enhanced screening of human immunodeficiency virus-positive patients for cancer. This paper covers the broad spectrum of disease entities likely to be encountered with human immunodeficiency virus-related cytopathology.

Abstract
Human papillomavirus (HPV) is the most common sexually transmitted infection. The effect of HPV on public health is especially related to the burden of anogenital cancers, most notably cervical cancer. Determinants of exposure to HPV are similar to those for most sexually transmitted infections, but determinants of susceptibility and infectivity are much less well established. Gaps exist in understanding of interactions between HPV, HIV, and other sexually transmitted infections. The roles of mucosal immunology, human microbiota at mucosal surfaces, host genetic factors and hormonal concentrations on HPV susceptibility and infectivity are poorly understood, as are the level of effectiveness of some primary or secondary preventive measures other than HPV vaccination (such as condoms, male circumcision, and combination antiretroviral therapy for HIV). Prospective couples studies, studies focusing on mucosal immunology, and in-vitro raft culture studies mimicking HPV infection might increase understanding of the dynamics of HPV transmission.

Abstract
Background The implementation of highly active antiretroviral therapy (HAART) among HIV-positive patients results in immune reconstitution, slower progression of HIV disease, and a decrease in the occurrence of opportunistic infections. However, the impact of HAART on cervical human papillomavirus (HPV) infection, clearance, and persistence in high-risk adolescents remains controversial. Methods HIV-positive and high-risk HIV-negative female adolescents were enrolled in the Reaching for Excellence in Adolescent Care and Health (REACH) longitudinal cohort study. At each semi-annual clinical visit, cervical lavage samples were tested for 30 HPV types. Type-specific and carcinogenic risk-specific HPV prevalence and incidence were compared in 373 eligible participants: 146 HIV-negative female adolescents with a median follow-up of 721.5 [IQR: 483-1301] days and 227 HIV-positive female adolescents. Of the 227 HIV-positive participants, a fixed set (n = 100) were examined both before and after HAART initiation; 70 were examined only before HAART initiation; and 57 were examined only after HAART initiation, with overall median follow-up of 271 [IQR: 86.5-473] and 427.25 [IQR: 200-871] days respectively for before and after HAART initiation. Results Of the 373 eligible participants, 262 (70%) were infected with at least one type of HPV at baseline, and 78 of the remaining 111 (70%) became infected with at least one type of HPV by the end of the study. Overall, the incidence and prevalence of HPV types 58, 53/66, 68/70, and 31/33/35 were much higher than the established carcinogenic and HPV vaccine types 16 and 18, especially in HIV-positive females both before and after HAART initiation. Baseline prevalence for individual high-risk HPV types ranged, depending on type, from 0.7-10%, 1-17%, and 1-18% in the HIV-negative group, the HIV-positive before HAART initiation group, and the HIV-positive after HAART initiation group, respectively. Likewise, the incidence ranged, depending on HPV type, from 0.64-9.83 cases/100 PY, 3.00-12.80 cases/100 PY, and 1.49-17.05 cases/100 PY in the three groups, respectively. The patterns of each HPV type infection, clearance, and persistence did not differ considerably before or after the introduction of HAART and were clearly independent of CD4+ change within the short post-HAART follow-up period. Conclusions HAART did not immediately affect the incidence of type-specific HPV infections within a short-period follow-up; however, future studies are warranted in larger populations to evaluate HAART's impact over longer periods.

Abstract
OBJECTIVE To examine the association between CD4 counts, HPV infection and the risk of cervical neoplasia among HIV-seropositive women. METHODS A cross-sectional observational study was conducted among 1,010 HIV-seropositive women using cytology-based Pap smears. HPV DNA testing using Linear Array genotyping assay (Roche) was carried out in a subset of 191 patients. Multivariable-adjusted prevalence ratios (mPR) and 95% confidence intervals (CIs) were estimated with log-binomial regression. RESULTS Among 1,010 HIV-seropositive women, the prevalence of AGC/ASCUS, LSIL and HSIL or greater was 8.3, 23.5 and 18.0%, respectively. The risk of cervical lesions was higher with CD4 < 200 cells/mm(3) vs. CD4 levels > 500/mm(3). HPV types 16 (41.7%) and HPV 56 (22.2%) were the most common types in HSIL cases. Women with CD4 levels < 200/mm(3) had a higher prevalence of HPV types 16 (p < 0.01) and 66 (p = 0.04). No statistical relationship between cervical lesions and HAART use was found. CONCLUSION The burden of HPV infection and HSIL was high and correlated with HIV-induced immunosuppression. HPV 16 was the most common type in HSIL and increased in prevalence with greater immune suppression. Prophylactic HPV 16 vaccination could prevent approximately 40% of HSIL cases. Strengthening screening programs is imperative in this population.

Abstract
Women with HIV infection report elevated and persisting psychosocial distress, sleep difficulty, and fatigue. The objective of this study was to examine psychosocial distress, sleep difficulty, and fatigue in a group of lower socioeconomic status women co-infected with HIV and HPV (N = 60). After controlling for relevant health behavioral and medical variables, multiple regression analyses indicated that greater psychosocial distress was associated with greater fatigue (p < .01), as well as greater sleep difficulty (p < .01). Sleep difficulty partially mediated the relationship between distress and fatigue (Sobel test, z = 2.39, p = .02). Stress management and sleep-based cognitive behavioral intervention approaches may be useful for treating fatigue in these women, possibly through reductions in psychosocial distress and improvements in sleep quality.

Abstract
Persons infected with HIV are at increased risk for all cancers known or suspected to have an infectious cause, an effect believed to be primarily mediated by lowered host immunity via the depletion of CD4(+) cells. Whereas Kaposi sarcoma and non-Hodgkin lymphoma were recognised as AIDS-defining illnesses early in the HIV epidemic, the influence of declining CD4(+) count on other infection-related cancers has taken longer to establish, undoubtedly because the association is weaker and the dose-response relationship is less steep. However, following improved survival made possible by combined antiretroviral therapy, declining CD4(+) count starts showing an impact on the natural history of various carcinogenic infections and on the risk for an increasingly wide range of cancers, including Hodgkin lymphoma, cervical, anal and liver cancers.

Abstract
The objective of this study was to review the literature on the epidemiological association between human papillomavirus (HPV), HIV, and cervical neoplasia, and the impact of highly active antiretroviral therapy (HAART) on this association. MEDLINE was searched using the terms 'human papillomavirus', 'HPV', 'HIV', 'cervix', 'neoplasm', and 'antiretroviral' to identify articles published before December 2006. HIV-infection was strongly associated with a higher prevalence, incidence, and persistence of HPV infection and correlated with prevalence, incidence, persistence, and progression of squamous intraepithelial lesions. The association between HIV and invasive cervical carcinoma has been more difficult to establish, but is now fully recognized. HAART seems to have little, if any, beneficial effect on the natural history of intraepithelial lesions in HIV-positive women. Despite this fact, HAART, does increase the life expectancy of HIV-positive women. Therefore, it remains important to closely monitor HPV-related disease in women with HIV who are receiving HAART, particularly in regions of the world where cervical screening is not available routinely.

Abstract
OBJECTIVE To determine the cost effectiveness of several cervical cancer screening strategies utilizing HPV testing in South Africa. METHODS We developed a lifetime Markov model of the costs, quality of life, and survival associated with screening and treating cervical cancer and its precursors. Screening strategies evaluated included: 1) conventional cytology, 2) cytology followed by HPV testing for triage of equivocal cytology, 3) HPV testing, 4) HPV testing followed by cytology for triage of HPV-positive women, and 5) co-screening with cytology and HPV testing. Primary outcome measures included quality-adjusted life-years saved (QALYs), incremental cost-effectiveness ratios, and lifetime risk of cervical cancer. Costs are in 2006 South African Rand (R). RESULTS In a cohort of 100,000 women, starting at age 30 and screening once every 10 years reduced the lifetime risk of cervical cancer by 13-52% depending on the screening strategy used, at an incremental cost of R13,000-R42,000 per QALY. When strategies were compared incrementally, cytology with HPV triage was less expensive and more effective than screening using cytology alone. HPV testing with the use of cytology triage was a more effective strategy and costs an additional R42,121 per QALY. HPV testing with colposcopy for HPV-positive women was the next most effective option at an incremental cost of R1541 per QALY. Simultaneous HPV testing and cytology co-screening was the most effective strategy and had an incremental cost of R25,414 per QALY. CONCLUSIONS In our model, HPV testing to screen for cervical cancer and its precursors is a cost-effective strategy in South Africa.

Abstract
OBJECTIVES Human papillomavirus (HPV) infection is a major risk factor for cervical disease. Using baseline data from the HIV-infected cohort of Evandro Chagas Clinical Research Institute at Fiocruz, Rio de Janeiro, Brazil, factors associated with an increased prevalence of HPV were assessed. METHODS Samples from 634 HIV-infected women were tested for the presence of HPV infection using hybrid capture II and polymerase chain reaction. Prevalence ratios (PR) were estimated using Poisson regression analysis with robust variance. RESULTS The overall prevalence of HPV infection was 48%, of which 94% were infected with a high-risk HPV. In multivariate analysis, factors independently associated with infection with high-risk HPV type were: younger age (<30 years of age; PR 1.5, 95% confidence interval (CI) 1.1-2.1), current or prior drug use (PR 1.3, 95% CI 1.0-1.6), self-reported history of HPV infection (PR 1.2, 95% CI 0.96-1.6), condom use in the last sexual intercourse (PR 1.3, 95% CI 1.1-1.7), and nadir CD4+ T-cell count <100cells/mm(3) (PR 1.6, 95% CI 1.2-2.1). CONCLUSIONS The estimated prevalence of high-risk HPV-infection among HIV-infected women from Rio de Janeiro, Brazil, was high. Close monitoring of HPV-related effects is warranted in all HIV-infected women, in particular those of younger age and advanced immunosuppression.

Abstract
We re-sequenced HPV16 genome (~6 kb) implicated in cervical carcinogenesis (LCR, E2, E5, E6, E7, L1, L2) to prioritize sequence variants for functional validation as biomarkers, using CaCx cases (n=74) and asymptomatic controls (n=24). Of the nucleotide variations recorded (n=271), non-synonymous changes in L2 region were significantly higher (p=0.005) among cases (2.67%) compared to controls (1.27%). Using SIFT database, 29 non-synonymous changes (frequency=0.01-0.03) predicted as deleterious to protein functions were identified. Haplotype analysis considering 110 polymorphic variations (frequency> or =0.05) within intact viral isolates (53 CaCx cases and 21 controls) using NETWORK software, confirmed Asian-American (AA, 14.86%) and European (E, 85.14%) variants, differing at 78 positions. The E-variants portrayed thirty-six haplotypes, of which, E-12 was most prevalent within cases (38.1%; 16/42) and controls (28.57%; 6/21) harboring polymorphic variations at 10 positions, in contrast to HPV16R. Cases of the E-12 haplotype harbored 7 deleterious mutations distributed within L1 (n=1), E2 (n=1), E5 (n=1), and L2 (n=4), while none within similar controls. Thus rare deleterious variations within genes implicated in productive infection over the E-12 haplotype background of intact HPV16 isolates might be of causal relevance for CaCx development.

Abstract
Objective. Animal data suggest that cocaine has an immunosuppressive effect, but no human studies have been conducted to assess the relation of cocaine use with human papillomavirus (HPV) infection, the viral cause of cervical cancer. Since both cocaine use and HPV infection are common among HIV-positive women, we sought to determine whether use of cocaine and/or crack influences the natural history of HPV among women with or at high risk of HIV.
Methods. Women enrolled in the Women's Interagency HIV Study (2278 HIV-seropositive and 826 high-risk seronegative women) were examined every six months for up to 9.5 years with Pap smear, collection of cervicovaginal lavage (CVL) samples, and detailed questionnaires regarding health and behavior, including use of crack and cocaine (crack/cocaine). CVLs were tested for HPV DNA by PCR, with genotyping for over forty HPV types.
Results. In multivariate logistic regression models, censoring women treated for cervical neoplasia, crack/cocaine use within the last six months was associated with prevalent detection of oncogenic HPV DNA (odds ratio [OR] = 1.30
(1.09–1.55)), and with oncogenic HPV-positive squamous intraepithelial lesions (SIL) (OR = 1.70 (1.27–2.27)), following adjustment for age, race, HIV-serostatus, and CD4+ T-cell count, the number of sexual partners in the past six months, and smoking. In multivariate Cox models crack/cocaine use was also associated with a trend that approached significance in regard to incident detection of oncogenic HPV-positive SIL (HR = 1.51, 95% CI 0.99–2.30), and while the rate of oncogenic HPV clearance was not related to cocaine use, the clearance of any SIL was significantly lower in those with versus those without recent crack/cocaine use (HR = 0.57, 95% CI 0.34–0.97).
Conclusions. Cocaine use is associated with an increased risk of detection of both prevalent and incident oncogenic HPV infection, as well as an increased risk of HPV-positive SIL over time.

Abstract
OBJECTIVES To evaluate the prevalence of human papillomavirus (HPV) types, and risk factors for HPV positivity across cervix, vagina and anus, we conducted a study among 138 women with human immunodeficiency virus (HIV). GOAL Compare the prevalence of different HPV types and the risk factors for HPV positivity in three sites. RESULTS The most frequently detected HPV types in all sites were, in decreasing order, HPV16, 53, 18, 61 and 81. Agreement between the cervix and vagina was good (kappa 0.60 - 0.80) for HPV16 and 53 and excellent (Kappa > 0.80) for HPV18 and 61. HPV positivity was inversely associated with age for all combinations including the anal site. CONCLUSION In HIV positive women, HPV18 is the most spread HPV type found in combinations of anal and genital sites. The relationship of anal to genital infection has implications for the development of anal malignancies. Thus, the efficacy of the current HPV vaccine may be considered not only for the cervix, but also for prevention of HPV18 anal infection among immunossuppressed individuals.

Abstract
The aim of the study was to estimate the prevalence and risk factors associated with infection by high-risk human papillomavirus (HR-HPV) in cervix and squamous intra-epithelial lesions (SIL) in imprisoned women. This was done by a cross-sectional study of imprisoned women attending the gynaecological clinic in Foncalent prison in Alicante, Spain. The study period was from May 2003 to December 2005. HR-HPV infection was determined through Digene HPV Test, Hybrid Capture II (HC-II). HPV typing was determined by multiplex nested PCR assay combining degenerate E6/E7 consensus primers. Multiple logistic regression modelling was used for the analysis of associations between variables where some were considered possible confounders after checking for interactions. A total of 219 women were studied. HR-HPV prevalence was 27.4% and prevalence of SIL was 13.3%. HIV prevalence was 18%, higher in Spaniards than in migrant women (24.6% vs. 14.3%, P<0.05). In multivariate analyses, risk factors for HPV infection were younger age (P for trend=0.001) and tobacco use (OR 2.62, 95% CI 1.01-6.73). HPV infection (OR 4.8, 95% CI 1.7-13.8) and HIV infection were associated with SIL (OR 4.8, 95% CI 1.6-14.1). The commonest HPV types were HPV16 (29.4%), HPV18 (17.6%), HPV39 (17.6%) and HPV68 (17.6%). The prevalence of both HR-HPV infection and SIL in imprisoned women found in this study is high. Determinants for each of the outcomes studied were different. HPV infection is the most important determinant for SIL. A strong effect of HIV co-infection on the prevalence of SIL has been detected. Our findings reinforce the need to support gynaecological clinics in the prison setting.

Abstract
The influence of HAART on the evolution to cervical squamous intraepithelial lesions (SIL) among HIV(+) women with a normal cytological test in the HAART era was studied. A retrospective cohort study (1997-2005) of HIV-infected women treated with HAART was conducted. Those with a normal cervical cytology (Papanicolaou test) and at least one subsequent test were included. Survival (time until diagnosis of SIL), univariate, and multivariate analyses were performed. A total of 133 HIV-infected patients treated with HAART were included. The incidence of SIL was 35% (47 patients). SIL was diagnosed in 36 of 110 (33%) patients with a baseline and final immunological status of >200 CD4 cells/microl and in 6 of 9 (67%) patients with a baseline and final immunological status of < or =200 CD4 (OR: 0.24, 95% CI: 0.06-1.03, p = 0.041). SIL was diagnosed in 10 of 60 (17%) patients with an undetectable baseline and final HIV viral load and in 36 of 70 (51%) patients with a detectable HIV viral load (OR: 0.19, 95% CI: 0.07-0.46, p < 0.001). A high incidence of SIL (cancer precursor lesions) was observed among HIV(+) women without a background of cervical pathology. The effect of HAART on the control of HIV replication and of immunological status (>200 CD4) through the follow-up was associated with a reduction of SIL.

Abstract
Human papillomavirus (HPV) infection is etiologically associated with a subset of oral cancers, and yet, the natural history of oral HPV infection remains unexplored. The feasibility of studying oral HPV natural history was evaluated by collecting oral rinse samples on 2 occasions at a 6-month interval from 136 HIV-positive and 63 HIV-negative participants. Cervical vaginal lavage samples were concurrently collected for comparison. HPV genomic DNA was detected in oral and cervical samples by consensus primer PCR and type-specified for 37 HPV types. The six-month cumulative prevalence of oral HPV infection was significantly less than for cervical infection (p < 0.0001). HIV-positive women were more likely than HIV-negative women to have an oral (33 vs. 15%, p = 0.016) or cervical (78 vs. 51%, p < 0.001) infection detected. Oral HPV infections detected at baseline were as likely as cervical infections to persist to 6 months among HIV-negative (60% vs. 51%, p = 0.70) and HIV-positive (55% vs. 63%, p = 0.27) women. Factors that independently elevated odds for oral HPV persistence differed from cervical infection and included current smoking (OR = 8, 95% CI = 1.3-53), age above 44 years (OR = 20, 95% CI = 4.1-83), CD4 < 500 (OR = 6, 95% CI = 1.1-26), use of HAART therapy (OR = 12, 95% CI = 1.0-156), and time on HAART therapy (trend p = 0.04). The rate of oral HPV infections newly detected at follow-up was significantly lower than cervical infection among HIV-positive (p < 0.001) and HIV-negative women (p < 0.001). Our study not only demonstrates that it is feasible to study the natural history of oral HPV infection with oral rinse sampling, but also indicates that oral and cervical HPV natural history may differ.
