Abstract
Background: HIV-positive men who have sex with men (MSM) are more likely to experience human papillomavirus (HPV) infection. The persistent HPV infection is the major factor in the development of anal and oropharyngeal neoplasms. Data on the prevalence of anal and oral HPV in MSM are almost absent from the countries of Central and Eastern Europe. We conducted a cross-sectional study focused on the prevalence of oral and anal HPV infections and the relationship between current anal and oral HPV intrapersonal infection in a Czech population of predominantly HIV-positive MSM. Methods: Oral gargle and anal swab samples from 205 predominantly HIV-positive MSM from the Czech Republic were analysed for HPV infection using PCR. Selected sociodemographic and clinical data were correlated with HPV detection using generalized linear models and multivariate analysis. Results: HPV infection was detected in 183 (96.8%) anal and 48 (23.6%) oral samples. The most common type of HR-HPV was HPV16 in both anal (25.4%) and oral (2.5%) samples. Multiple anal HPV infections and the presence of vaccine-targeted HR-HPV types were significantly correlated with abnormal anal cytology and HIV status. Conclusion: The prevalence of anal HPV infection in Czech predominantly HIV-positive MSM ranks among the highest reported, while oral HPV prevalence is consistent with MSM populations. Minimal overlap of oral and anal HPV types within a patient was observed.

Abstract
BACKGROUND Incidence of anal squamous cell carcinoma (SCC) has increased in the U.S. Persons living with HIV (PLWH) have an elevated risk of anal SCC, and changes in the number of anal SCCs among PLWH may have influenced general population trends. METHODS Data were obtained from a linkage of HIV and cancer registries in 12 U.S. regions. The proportion of anal SCCs occurring among PLWH was estimated by sex, age group and race and ethnicity. To assess the impact of anal SCCs among PLWH on general population trends, annual percentage changes (APCs) in incidence rates including and excluding anal SCCs among PLWH were estimated. RESULTS Between 2001-2015, 14.5% of 16,110 anal SCC diagnoses occurred in PLWH. In 2013-2015, 33% of anal SCCs among men occurred in PLWH, but only 3% among women. The proportion of anal SCCs among PLWH was highest among 20-49-year-olds and Black and Hispanic individuals. General population anal SCC trends among men were strongly influenced by cases among PLWH: rates increased 4.6%/year [95% confidence interval (CI): 1.4%, 8.0%] from 2001-2009 followed by a non-significant decline (APC: -2.7%/year [95%CI: -7.1, 2.0%]) from 2009-2015, but without anal SCCs among PLWH, rates were stable (APC: 0.7%, [95%CI: -0.8%-2.3%]). Anal SCC rates among women increased 3.8%/year (95%CI 3.2%-4.4%) during 2001-2012 and then declined non-significantly (APC=-3.8; 95%CI -6.9, -0.6), and anal SCCs among PLWH had little impact on these trends. CONCLUSION During 2001-2015, anal SCCs among PLWH contributed strongly to changes in incidence trends in the general U.S. population among men, but not women.

Abstract
BACKGROUND Human papillomavirus (HPV) is one of the most common sexually transmitted viruses nowadays.
AIM To analyze the prevalence of HPV infection in human immunodeficiency virus (HIV)-positive patients and the risk factors associated with this infection through a review of studies published in the period from January 2010 to April 2020.
METHODS A total of 384 articles were initially identified in our searches, of which ten were selected according to previously defined eligibility criteria.
RESULTS Anal intercourse, absence of condom use, multiple partners, other specific sexual and life habits, and HIV infection are among the risk factors associated with anal HPV infection.
CONCLUSION In general, there is a higher prevalence of anal HPV infection among HIV-positive patients, mostly in individuals over 30 years old, those with multiple partners, those who had an early homosexual debut, and cigarette, alcohol, and drug users.

Prevalence and genotype distribution of human papillomavirus infection in different anatomical sites among men who have sex with men: A systematic review and meta-analysis. Rev Med Virol 2021; 31:e2219. [PMID: 33527636 DOI: 10.1002/rmv.2219] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2020] [Revised: 01/07/2021] [Accepted: 01/12/2021] [Indexed: 12/15/2022]
Abstract
Men who have sex with men (MSM) are at increased risk of human papillomavirus (HPV) infection because of their high-risk sexual behaviours. In this study, a meta-analytic approach was used to systematically analyse the literature to elucidate the prevalence and genotype distribution of anal, penile, oral and urethral HPV infection among MSM in the world. To carry out this systematic review, five electronic databases including Web of Science, PubMed, Scopus, Embase, and Google Scholar were searched for relevant studies published from January 2012 to November 2019, and pertinent data were collected from the eligible articles. The pooled HPV prevalence was calculated for each anatomical region using a random-effect model weighted by the inverse variance method. The meta-analysis was performed using the "Metaprop" function in the R package Meta. The overall pooled prevalence of anal, penile, oral and urethral HPV infection among MSM were 78.4% (95% confidence interval [CI]: 75.6%-81.0%), 36.2% (95% CI: 29.1%-44.0%), 17.3% (95% CI: 13.6%-21.7%) and 15.4% (95% CI: 7.8%-27.9%), respectively. Stratified analyses showed that the prevalences of HPV were significantly higher in HIV-positive than HIV-negative MSM. The most frequent HPV high-risk type detected in the anus, penis and oral cavity was HPV-16 (19.9%, 4.9% and 3.1%, respectively). HPV infection is rising in MSM because of high-risk sexual behaviours, suggesting an increased future risk of developing HPV-related diseases and malignancies in this population.

Association of antiretroviral therapy with anal high-risk human papillomavirus, anal intraepithelial neoplasia, and anal cancer in people living with HIV: a systematic review and meta-analysis. Lancet HIV 2020; 7:e262-e278. [PMID: 32109408 DOI: 10.1016/s2352-3018(19)30434-5] [Citation(s) in RCA: 46] [Impact Index Per Article: 11.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2019] [Revised: 12/12/2019] [Accepted: 12/19/2019] [Indexed: 02/08/2023]
Abstract
BACKGROUND The effect of antiretroviral therapy (ART) on the natural history of anal high-risk HPV and anal lesion progression is not well established. We reviewed the association of ART and other HIV-related factors on anal HPV infection, anal intraepithelial neoplasia (AIN), and anal cancer among people living with HIV. METHODS For this systematic review and meta-analysis, we searched MEDLINE and EMBASE for studies published between Jan 1, 1996, and Oct 30, 2019, that reported the association of HIV-related exposures (ART or highly active ART [HAART], HIV-RNA plasma viral load [PVL], and nadir or current CD4 cell count) with outcomes of anal high-risk HPV prevalence, incidence, and persistence; prevalence, incidence, progression, or regression of anal histological and cytological abnormalities; and anal cancer incidence. Effect estimates were extracted whenever available; otherwise, they were calculated from raw data. We assessed the risk of bias of included studies using the Newcastle-Ottawa scale, and random-effects meta-analyses were done to examine heterogeneity using the I2 statistic. This study is registered on the PROSPERO database, CRD42018007271. FINDINGS We identified 6777 studies, of which 5377 were excluded before full-text review. 122 studies providing estimates for 130 distinct populations matched the inclusion criteria. The populations comprised 417 006 people living with HIV (women, men who have sex with men, and men who have sex with women). 41 (32%) population estimates were not stratified by sex or sexual orientation. People living with HIV receiving ART had 35% lower high-risk HPV prevalence than ART-naive people (crude odds ratio [OR] 0·65, 95% CI 0·54-0·79; I2 12·1%, p=0·31) in 18 studies, and prolonged ART use was associated with a 10% reduction per year in high-risk HPV prevalence in two studies (adjusted OR 0·90, 0·85-0·95; I2 0%, p=0·88). People living with HIV with undetectable PVL had lower HSIL-AIN2+ prevalence than those with detectable PVL (crude OR 0·84, 0·72-0·98; I2 0%, p=0·80) in 16 studies, particularly if sustained for more than 1 year (crude OR 0·62, 0·47-0·81; I2 0%, p=0·51). ART was not associated with anal cancer incidence when adjusted for years living with HIV in three studies (adjusted hazard ratio [HR] 1·11, 95% CI 0·68-1·80; I2 0%, p=0·57), but ART users with sustained undetectable HIV PVL had 44% lower risk of anal cancer than those without (adjusted HR 0·56, 0·44-0·70; I2 0%, p=0·94) and for each increase in nadir CD4 cell counts of 100 cells per μL, there was a 40% decrease in anal cancer incidence (crude HR 0·60, 0·46-0·78; I2 21·7%, p=0·26). INTERPRETATION Effective ART use and early initiation at high nadir CD4 counts might reduce anal high-risk HPV infection and anal cancer risk. Although most studies were cross-sectional in design and few adjusted for potential confounders, this analysis provides comprehensive estimates of the effect of ART and HIV-related factors on the natural history of anal HPV-related disease in people living with HIV.

Abstract
BACKGROUND Few studies have examined outcomes of high-resolution anoscopy (HRA)-based screening for people with HIV infection (PWH), a population at increased risk for anal cancer. SETTING Large integrated health care system. METHODS Cohort study of 13,552 people with HIV infection, comparing incidences of anal cancer and advanced anal cancer (higher stage, recurrence, death, or surgical salvage) before and after HRA became available (2008). Calendar time was divided as 1998-2007, 2008-2010, and 2011-2012. Rate ratios (RRs) were obtained from Poisson regression models with adjustment for baseline demographic and health variables. Cohort cases during 2008-2012 were included in a nested case-control study, evaluating association of screening with anal cancer (33 cases, 330 controls) and advanced anal cancer (19 cases, 190 controls). Odds ratios (ORs) for receipt of screening were obtained from conditional logistic regression models with adjustment for baseline demographic and health history variables. RESULTS Compared with 1998-2007 (pre-HRA), 2008-2010 adjusted RRs were 1.32 [95% confidence intervals (CI): 0.77 to 2.27; P = 0.31] for anal cancer and 2.11 (95% CI: 0.99 to 4.48; P = 0.053) for advanced anal cancer; and 2011-2012 adjusted RRs were 0.35 (95% CI: 0.12 to 0.99; P = 0.048) for anal cancer and 0.23 (95% CI: 0.03 to 1.77; P = 0.16) for advanced anal cancer. Individual history of screening did not reach statistical significance for anal cancer (OR 1.7; 0.6-4.6) or advanced anal cancer (OR 0.44; 0.1-3.8). CONCLUSIONS Despite the possible effect of secular trends, we found 2008-2012 incidence trends for anal cancer and advanced anal cancer that seem consistent with expected findings of a beneficial screening program.

Abstract
Background Few studies focused on longitudinal modifications over time of high-risk HPV (HR-HPV) at anal and oral sites in HIV+ men who have sex with men (MSM). Methods We described patterns and longitudinal changes of HR-HPV detection and the prevalence of HR-HPV covered by the nonavalent HPV vaccine (vax-HPV) at oral and anal sites in 165 HIV+ MSM followed in an Italian hospital. The samples were collected at baseline and after 24 months (follow-up). The presence of HPV was investigated with Inno-LiPA HPV Genotyping Extra II. Results Median age was 44 years (IQR 36–53), median CD4+ cell count at nadir was 312 cells/mm3 (IQR 187–450). A total of 120 subjects (72.7%) were receiving successful antiretroviral therapy (ART). At baseline and follow-up, the frequency of HR-HPV was significantly higher in the anal site (65.4% vs 9.4 and 62.4% vs 6.8%, respectively). Only 2.9% of subjects were persistently HR-HPV negative at both sites. All oral HR-HPV were single at baseline vs 54.6% at baseline at the anal site (p = 0.005), and all oral HR-HPV were single at follow-up vs 54.4% at anal site at follow-up (p = 0.002). The lowest rate of concordance between the oral and anal results was found for HR-HPV detection; almost all HR-HPV positive results at both anal and oral sites had different HR-HPV.The most frequent HR-HPV in anal swabs at baseline and follow-up were HPV-16 and HPV-52.At follow-up at anal site, 37.5% of patients had different HR-HPV genotypes respect to baseline, 28.8% of subjects with 1 HR-HPV at baseline had an increased number of HR-HPV, and patients on ART showed a lower frequency of confirmed anal HR-HPV detection than untreated patients (p = 0.03) over time. Additionally,54.6 and 50.5% of patients had only HR-vax-HPV at anal site at baseline and follow-up, respectively; 15.2% had only HR-vax-HPV at baseline and follow-up. Conclusions We believe that it is important testing multiple sites over time in HIV-positive MSM. ART seems to protect men from anal HR-HPV confirmed detection. Vaccination programmes could reduce the number of HR-HPV genotypes at anal site and the risk of the first HR-HPV acquisition at the oral site.

Comparison of nylon-flocked swab and Dacron swab cytology for anal HSIL detection in transgender women and gay, bisexual, and other men who have sex with men. Cancer Cytopathol 2019; 127:247-257.

Abstract
BACKGROUND An anal histological high-grade squamous intraepithelial lesion (hHSIL) is an anal cancer precursor. Experts recommend Dacron swab anal cytology as a primary screen for anal hHSILs, especially among human immunodeficiency virus-infected and -uninfected men who have sex with men (MSM). Studies have shown that Dacron cytology inaccurately predicts anal hHSILs and results in unnecessary diagnostic procedures. Nylon-flocked (NF) swabs have been shown to trap pathogens and cells well. Thus, this study compared test characteristics of anal cytology using NF and Dacron swab collection protocols to predict anal hHSILs. METHODS A single-visit, randomized clinical trial compared NF and Dacron swab anal cytology specimens to predict high-resolution anoscopy and biopsy-diagnosed anal hHSILs. Data for 326 gay men, bisexual men, other MSM, and male-to-female transgender women contributed descriptive and tabular statistics with which unadjusted and fully adjusted logistic regression models were constructed. The models estimated the odds of hHSILs, test accuracy (area under the curve [AUC]) and sensitivity, and specificity as well as the positive and negative predictive values of abnormal NF and Dacron cytology for predicting hHSILs. RESULTS In the fully adjusted model, the sensitivities for NF and Dacron cytology were nearly equal (48% vs 47%), but the specificity was higher with NF cytology (76% vs 69%). Comparisons of the areas under receiver operating characteristic curves showed that NF cytology alone predicted hHSILs better than the covariate model (AUC, 0.69 vs 0.63; P = .02), but NF and Dacron cytology comparisons showed no statistically significant differences (AUC, 0.69 vs 0.67; P = .3). CONCLUSIONS NF cytology and Dacron cytology provide modest sensitivity, but NF cytology has higher specificity and accuracy, and this is important for lowering the costs of population-based screening.

Cancer Cytopathol 2018; 126:447-460. [PMID: 29797691 DOI: 10.1002/cncy.22018] [Citation(s) in RCA: 64] [Impact Index Per Article: 10.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2018] [Revised: 03/26/2018] [Accepted: 04/18/2018] [Indexed: 12/14/2022]
Abstract
Anal cancer incidence and mortality have been increasing over the past decade. Although the incidence in the general population remains low, it is much higher in certain subgroups, including those living with human immunodeficiency virus and men who have sex with men. Approximately 90% of anal squamous cell cancers are caused by infection with carcinogenic human papillomavirus (HPV). Given the common etiology between anal and cervical carcinogenesis, screening for anal cancer has been proposed in certain high-risk populations using strategies adapted from cervical cancer prevention. In this review, the authors discuss important differences in anal and cervical cancer regarding the populations at risk, disease natural history, and clinical procedures and outcomes that need to be considered when evaluating strategies for anal cancer screening. They also performed a systematic review and meta-analysis of the performance of anal cytology, anal HPV testing, and various biomarkers for the detection of anal precancers and cancers. The implications of these performance estimates are summarized in the context of risk-based screening and management of anal precancers, and important research gaps are highlighted that need to be addressed to fully understand the benefits and harms of anal cancer screening.

Abstract
BACKGROUND Little is known about human papillomavirus (HPV) infection and genotypes when considering both anatomic site and human immunodeficiency virus (HIV) status among men who have sex with men (MSM) in low- and middle-income countries. METHODS A cross-sectional study was conducted among MSM in Beijing, China. HIV serostatus was determined, and genital and anal HPV genotyping were performed from respective swabs. RESULTS Of 1155 MSM, 817 (70.7%) had testing for genital (611; 52.9%) and/or anal (671; 58.1%) HPV. Preference for insertive anal sex (adjusted odds ratio [aOR], 2.60; 95% confidence interval [CI], 1.42-4.75) and syphilis (aOR, 1.50; 95% CI, 1.01-2.23) were associated with genital HPV. Inconsistent condom use during receptive anal sex (aOR, 1.82; 95% CI, 1.17-2.84), and HIV seropositivity (aOR, 2.90; 95% CI, 1.91-4.42) were associated with anal HPV. Among 465 (40.3%) MSM with specimens from both anatomic sites, anal HPV (68%) was more common than genital HPV (37.8%). Prevalence of anal HPV was higher among HIV-infected than uninfected MSM (P < 0.01). Some oncogenic HPV types were more commonly found at the anal site of HIV-infected MSM (P < 0.01). CONCLUSIONS Human papillomavirus is highly prevalent among Chinese MSM. Anal HPV was more common than genital HPV, and HIV seropositivity was associated with oncogenic HPV types at the anal site.

Abstract
Background Young men who have sex with men (MSM) are at increased risk for human papillomavirus (HPV)-associated disease as a result of HPV infection. Our objective was to characterize the prevalence of high-risk anal HPV infection and factors associated with prevalence in a group of young, primarily black MSM in Houston, Texas. Methods MSM aged 18-29 years were recruited using a respondent-driven sampling method to study HIV and sexually transmitted disease transmission and risk. All engaged in peer-recruitment chains and self-collected anal exfoliated cells. Prevalence ratios assessed factors associated with high-risk HPV and HPV types in the 9-valent vaccine. Results Black race was reported by 87% of men. Slightly over one half (53%) were human immunodeficiency virus (HIV) positive. Approximately 75% of men had at least 1 high-risk HPV type, and 39% of HIV-positive men harbored HPV-16. Analysis that controlled for potential confounders revealed that only HIV infection was associated with high-risk HPV infection. Conclusion Black MSM would benefit from increased HPV vaccination efforts, owing to high rates of HPV infection, increased HPV disease, and low vaccination series completion rates in this population.

Abstract
Survival with human immunodeficiency virus (HIV) infection has greatly improved due to effective antiretroviral therapy (ART). As infectious complications have declined, malignancy now accounts for over one-third of deaths among people living with HIV (PLWH). Based on practices in the general population, cancer screening of PLWH can decrease both morbidity and mortality. In this article, we review and consider directed approaches for colorectal, breast, cervical and lung cancer screening. Furthermore, routine physical examinations may detect lymphomas and skin, anal and oral cancers. Comprehensive cancer prevention in PLWH should also include ART adherence, vaccination against oncogenic viruses, treatment of hepatitis viruses and smoking cessation. Cancer screening for PLWH warrants further research on safety and efficacy as well as targeted efforts to increase adherence.

Abstract
BACKGROUND Sexually transmitted infections (STIs), including human immunodeficiency virus (HIV), disproportionately affect adolescents and young adults (AYAs) ages 13-24 years. Sexually transmitted infections likewise are a risk factor for HIV acquisition and transmission; however, there is a lack of data on STI acquisition in HIV-infected AYAs. METHODS We determined the incidence of STIs in HIV-infected AYAs 12.5 <25 years of age in the International Maternal Pediatric Adolescent AIDS Clinical Trials (IMPAACT) P1074 observational cohort study. Univariate and multivariable logistic regression models were used to evaluate the association of HIV control (mean viral load <500 copies/mL and CD4+ T cells >500 cells/mm3 in the year preceding STI diagnosis) and other risk factors with STI occurrence. RESULTS Of 1201 enrolled subjects, 1042 participants met age criteria and were included (49% male, 61% black, 88% perinatally infected; mean age 18.3 years). One hundred twenty participants had at least 1 STI on study, of whom 93 had their first lifetime STI (incidence rate = 2.8/100 person-years). For individual STI categories, 155 incident category-specific events were reported; human papillomavirus (HPV) and chlamydial infections were the most common. In the multivariable model, having an STI was associated with older age (adjusted odds ratio [aOR] = 1.13; 95% confidence interval [CI], 1.05-1.22), female sex (aOR = 2.65; 95% CI, 1.67-4.21), nonperinatal HIV acquisition (aOR = 2.33; 95% CI, 1.29-4.22), and uncontrolled HIV infection (aOR = 2.05; 95% CI, 1.29-3.25). CONCLUSIONS Sexually transmitted infection acquisition in HIV-infected AYAs is associated with older age, female sex, nonperinatal HIV acquisition, and poorly controlled HIV infection. Substantial rates of STIs among HIV-infected AYAs support enhanced preventive interventions, including safe-sex practices and HPV vaccination, and antiretroviral adherence strategies.

Abstract
Anal squamous cell carcinoma (SCC) is the fourth most prevalent cancer in human immunodeficiency virus (HIV)-infected men who have sex with men (MSM). Human papillomavirus (HPV) has been detected in over 90% of anal carcinoma biopsy specimens from MSM, and is considered a necessary, but alone, insufficient factor for carcinogenesis. Anal intraepithelial neoplasia (AIN) may be precursive for SCC, and screening cytology with referral of persons with abnormality for high-resolution anoscopy-guided biopsy, and AIN treatment, has been recommended for prevention. In the absence of either randomized controlled trials or surveillance data demonstrating a reduction in anal SCC incidence, these recommendations were based on analogy with cervical cancer. HPV-mediated genetic changes associated with cervical cancer, and aneuploidy, have been documented in AIN. However, little data exist on the rate of AIN progression to SCC. The treatment of AIN is frequently prolonged and not curative, and if routinized in the care of HIV-infected MSM, would likely be recurring well into their sixth decade of life. Clinical trials demonstrating a reduction in invasive anal carcinoma incidence, as well as acceptable morbidity with repeated AIN destruction, are needed before asking our patients to commit to routine treatment.

Abstract
Background It is unclear whether immunosuppression leads to younger ages at cancer diagnosis among people living with human immunodeficiency virus (PLWH). A previous study found that most cancers are not diagnosed at a younger age in people with AIDS, with the exception of anal and lung cancers. This study extends prior work to include all PLWH and examines associations between AIDS, CD4 count, and age at cancer diagnosis. Methods We compared the median age at cancer diagnosis between PLWH in the North American AIDS Cohort Collaboration on Research and Design and the general population using data from the Surveillance, Epidemiology and End Results Program. We used statistical weights to adjust for population differences. We also compared median age at cancer diagnosis by AIDS status and CD4 count. Results After adjusting for population differences, younger ages at diagnosis (P < .05) were observed for PLWH compared with the general population for lung (difference in medians = 4 years), anal (difference = 4), oral cavity/pharynx (difference = 2), and kidney cancers (difference = 2) and myeloma (difference = 4). Among PLWH, having an AIDS-defining event was associated with a younger age at myeloma diagnosis (difference = 4; P = .01), and CD4 count <200 cells/µL (vs ≥500) was associated with a younger age at lung cancer diagnosis (difference = 4; P = .006). Conclusions Among PLWH, most cancers are not diagnosed at younger ages. However, this study strengthens evidence that lung cancer, anal cancer, and myeloma are diagnosed at modestly younger ages, and also shows younger ages at diagnosis of oral cavity/pharynx and kidney cancers, possibly reflecting accelerated cancer progression, etiologic heterogeneity, or risk factor exposure in PLWH.

Abstract
Background Hepatitis B (HBV), hepatitis C (HCV) and other sexually transmitted infections (STIs) have been associated with HIV transmission risk and disease progression among gay men and other men who have sex with men (MSM), but the frequency and distribution of STIs in this community in Canada has not been extensively studied. Methods We recruited MSM living with and without HIV from a large primary care clinic in Toronto. Participants completed a detailed socio-behavioural questionnaire using ACASI and provided blood for syphilis, HIV, HBV and HCV, herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2), and human cytomegalovirus (CMV) serology, urine for chlamydia and gonorrhea, and a self-collected anal swab for human papillomavirus (HPV) molecular diagnostics. Prevalences were expressed as a proportion and compared using chi-square. Results 442 MSM were recruited, 294 living with HIV and 148 without. Active syphilis (11.0% vs. 3.4%), ever HBV (49.4% vs. 19.1%), HCV (10.4% vs. 3.4%), HSV-2 (55.9% vs. 38.2%), CMV (98.3% vs. 80.3%) and high-risk (HR) anal HPV (67.6% vs. 51.7%) infections were significantly more common in men living with HIV. Chlamydia and gonorrhea were infrequent in both groups. Regardless of HIV infection status, age and number of lifetime male sexual partners were associated with HBV infection and lifetime injection drug use with HCV infection. Conclusions Syphilis and viral infections, including HBV, HCV, HSV-2, CMV, and HR-HPV, were common in this clinic-based population of MSM in Toronto and more frequent among MSM living with HIV. This argues for the implementation of routine screening, vaccine-based prevention, and education programs in this high-risk population.

Abstract
BACKGROUND This study among men who have sex with men (MSM) aimed to (1) assess prevalence of anogenital low-risk human papillomavirus (lrHPV) infections, (2) evaluate associations with HIV infection, and (3) investigate lrHPV concordance. METHODS In 2010 to 2011, MSM 18 years or older were recruited in Amsterdam, the Netherlands, and provided anal and penile self-swabs (HIV & HPV in MSM study). Using the HPV SPF10-PCR/DEIA/LiPA25 system, the presence of lrHPV types 6, 11, 34, 40, 42, 43, 44, 53, 54, 66, 68/73, 70, and 74 could be detected. Logistic regression with generalized estimating equations was used to assess the independent effect of HIV on lrHPV infections. The model was repeated for lrHPV subcategories (nononcogenic and weakly oncogenic infections separately). Concordance was defined as detection of the same lrHPV type in both self-swabs of one individual. RESULTS A total of 778 MSM were included, of whom 317 (41%) were HIV positive (median CD4 count at enrollment, 530 cells/mm). Prevalence of anal lrHPV was 45% (95% confidence interval [CI], 41%-50%) in HIV-negative MSM and 69% (95% CI, 64%-74%) in HIV-positive MSM. Prevalence of penile lrHPV was 20% (95% CI, 16%-24%) and 37% (95% CI, 31%-42%), respectively. In multivariable analysis, HIV infection was independently associated with anal (adjusted odds ratio [aOR], 1.9; 95% CI, 1.5-2.3) and penile lrHPV (aOR, 2.0; 95% CI, 1.4-2.7). Nononcogenic and weakly oncogenic lrHPV subcategories showed a similar pattern of association. Anal lrHPV infections were strongly associated with the presence of a type-concordant penile infection (aOR, 5.8; 95% CI, 4.4-7.5) and vice versa (aOR, 5.7; 95% CI, 4.4-7.5). CONCLUSIONS Anal and penile infections with lrHPV are common in MSM. HIV infection was an independent determinant for lrHPV infections.

Abstract
BACKGROUND Prevalence estimates of anal high-risk human papillomavirus (HR-HPV) are needed in sub-Saharan Africa where HIV is endemic. This study evaluated anal HR-HPV in Nigeria among HIV-positive and HIV-negative men who have sex with men (MSM) for future immunization recommendations. METHODS We conducted a cross-sectional study to compare the prevalence of anal HR-HPV infections between 64 HIV-negative and 90 HIV-positive MSM. Multivariate Poisson regression analyses were used to examine demographic and behavioral risk factors associated with any HR-HPV infections. RESULTS The median age of the 154 participants was 25 years (interquartile range, 22-28 years; range, 16-38 years), and the median age at initiation of anal sex with another man was 16 years (interquartile range, 13-18 years; range, 7-29 years). The prevalence of anal HR-HPV was higher among HIV-positive than HIV-negative MSM (91.1% vs. 40.6%, P < 0.001). In the multivariate analysis, HIV infection (adjusted prevalence ratio [aPR], 2.02; 95% confidence interval [CI], 1.49-2.72), 10 years or more since anal sexual debut (aPR, 1.26; 95% CI, 1.07-1.49), and concurrent relationships with men (aPR, 1.32; 95% CI, 1.04-1.67) were associated with increased anal HR-HPV prevalence. CONCLUSIONS Anal HR-HPV infection is high for young Nigerian MSM, and rates are amplified in those coinfected with HIV. Providing universal coverage as well as catch-up immunization for young MSM may be an effective anal cancer prevention strategy in Nigeria.

An anal cancer screening program for MSM in Italy: Prevalence of multiple HPV types and vaccine-targeted infections. J Clin Virol 2015; 72:49-54. [PMID: 26397204 DOI: 10.1016/j.jcv.2015.09.001] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2015] [Revised: 09/06/2015] [Accepted: 09/07/2015] [Indexed: 12/16/2022]
Abstract
BACKGROUND Elevated HPV infection rates have been described in HIV-positive males, placing these subjects at high risk of anal neoplasia. Bivalent, quadrivalent, and nonavalent vaccines to prevent HPV infection have been developed, and recently proposed for gender-neutral immunization programs. OBJECTIVES In order to estimate the benefit that could be obtained by vaccination of HIV-positive men who have sex with men (MSM), we aimed at describing the frequency of multiple and vaccine-targeted HPV infections in MSM enrolled in an anal cancer screening program. STUDY DESIGN The anal cancer screening program was conducted between July 2009 and October 2012. Mucosal anal samples were tested for HPV DNA using MY09/MY11 PCR primers and, if positive, genotyped using the CLART2HPV Clinical Array (35HPV types). RESULTS A total of 220 MSM were screened and 88.6% were positive for HPV DNA: in 86.5% at least one high-risk (HR) type was found and in 13% only low-risk (LR) HPV were found. Multiple infections accounted for 84.5% of HPV DNA-positive cases and overall 160 different HPV genotype combinations were recognized (only three combinations were detected in more than one patient each). Based on strain coverage, at least one vaccine-targeted HPV type was found in 38.9%, 64%, and 78.4% of cases when considering bivalent, quadrivalent and nonavalent vaccines, respectively. At least one HR vaccine-targeted strain was found in 39% of MSM for bivalent and quadrivalent vaccines, and in 64% of cases for nonavalent prevention. CONCLUSIONS Anal HPV infections in unvaccinated mostly HIV-infected MSM are highly prevalent. The majority of this population has multiple infections with an extremely heterogeneous number of genotype combinations. The nonavalent vaccine could theoretically have prevented a minimum of one HR HPV type in two thirds of subjects.

Abstract
BACKGROUND HPV infection is common and may cause cancer among men who have sex with men (MSM). Anal HPV infection (HPV+) was found in 85% of HIV-positive (HIV+) and 59% of HIV-negative (HIV-) MSM in Bangkok, central Thailand. As little is known about HPV in this group in northern Thailand, we studied MSM subgroups comprised of gay men (GM), bisexual men (BM), and transgender women (TGW). METHODS From July 2012 through January 2013, 85 (42.5% of 200) GM, 30 (15%) BM, and 85 (42.5%) TGW who practiced receptive anal intercourse were recruited after informed consent, followed by self-assisted computer interview, HIV testing, and anal swabs for HPV genotyping. RESULTS Of 197 adequate specimens, the overall prevalence of any HPV was 157 (80%). Prevalence was 89% (76/85) in GM, 48% (14/29) in BM, and 81% (67/83) in TGW. The most common high-risk types were HPV16 (27% of 197), HPV58 (23%), and HPV51 (18%). Prevalence of high-risk types was 74% in 85 GM, 35% in 29 BM, and 71% in 83 TGW. Prevalence of any HPV type, or high-risk type, was 100% and 94%, respectively, among 48 HIV+ MSM, 70% and 54% among 120 HIV- MSM. Of the 197 specimens, 36% (70) had HPV types 16 and/or 18 in the bivalent vaccine, compared to 48% (95) with ≥1 of types 16/18/06/11 in the quadrivalent, 56% (111) for 16/18/31/33/45/52/58 in the 7-valent, and 64% (126) for 16/18/31/33/45/52/58/06/11 in the 9-valent. HIV+, GM, and TGW were independently associated with HPV infection. CONCLUSIONS We found higher rates of both any HPV and high-risk types than previous studies. Among the heretofore unstudied TGW, their equivalent HPV rates were comparable to GM. Current and investigational HPV vaccines could substantially protect GM, BM, and TGW from the serious consequences of HPV infection especially among HIV + MSM.

Abstract
Anal human papillomavirus (HPV) is prevalent among men who have sex with men (MSM), but has not been studied in the Russian Federation. A cross-sectional survey and HPV genotyping were conducted among HIV seropositive (n=58) and seronegative MSM (n=65)in Moscow. Multivariable logistic regression was performed to identify correlates of infection with oncogenic HPV genotypes 16 and/or 18 (HPV 16/18). Forty per cent (49/124) of all MSM were infected with at least one anal HPV genotype, 31.5% (39/124) had HPV16/18,and 11.5% (14/121) had high-grade squamous intraepithelial lesions (HSIL). HPV 16/18 was more prevalent in HIV seropositive than seronegative men (24/58,41.4% vs 15/65, 23.1%; p=0.03). HIV infection was independently associated with HPV 16/18 (adjusted odds ratio (AOR): 5.08; 95% confidence intervals (CI):1.49-17.34, p=0.01), as was having 2-4 steady male sex partners in the last year (vs ≤ 1 partner; AOR: 6.99;95%CI: 1.94–25.24, p<0.01). History of prison/detention,migration to/within Russia and use of incompatible lubricants were marginally associated with HPV16/18 (p<0.10). Comprehensive prevention options are needed to address HIV and HPV infection among MSM in Russia and may benefit from inclusion of young men in piloted HPV vaccination programmes.

Association between free testosterone levels and anal human papillomavirus types 16/18 infections in a cohort of men who have sex with men. PLoS One 2015; 10:e0119447. [PMID: 25794147 PMCID: PMC4368778 DOI: 10.1371/journal.pone.0119447] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2014] [Accepted: 01/26/2015] [Indexed: 01/17/2023] Open
Abstract
BACKGROUND Human papillomavirus (HPV) types 16 and 18 cause invasive cervical cancer and most invasive anal cancers (IACs). Overall, IAC rates are highest among men who have sex with men (MSM), especially MSM with HIV infection. Testosterone is prescribed for men showing hypogonadism and HIV-related wasting. While there are direct and indirect physiological effects of testosterone in males, its role in anal HPV16/18 infections in men is unknown. METHODS Free testosterone (FT) was measured in serum from 340 Multicenter AIDS Cohort Study (MACS) participants who were tested for anal HPV16/18-DNA approximately 36 months later. The effect of log10-transformed current FT level on anal HPV16/18 prevalence was modeled using Poisson regression with robust error variance. Multivariate models controlled for other HPV types, cumulative years of exogenous testosterone use, race, age, lifetime number of receptive anal intercourse partnerships, body mass index, tobacco smoking, HIV-infection and CD4+ T-cell counts among HIV-infected, and blood draw timing. RESULTS Participants were, on average, 60 (+5.4) years of age, White (86%), and HIV-uninfected (56%); Twenty-four percent tested positive for anal HPV16 and/or 18-DNA (HPV16 prevalence=17.1%, HPV18=9.1%). In adjusted analysis, each half-log10 increase of FT was associated with a 1.9-fold (95% Confidence Interval: 1.11, 3.24) higher HPV16/18 prevalence. Additionally, other Group 1 high-risk HPVs were associated with a 1.56-fold (1.03, 2.37) higher HPV16/18 prevalence. Traditional risk factors for HPV16/18 infection (age, tobacco smoking; lifetime number of sexual partners, including the number of receptive anal intercourse partnerships within 24 months preceding HPV testing) were poorly correlated with one another and not statistically significantly associated with higher prevalence of HPV16/18 infection in unadjusted and adjusted analyses. CONCLUSIONS Higher free testosterone was associated with increased HPV16/18 prevalence measured approximately three years later, independent of sexual behavior and other potential confounders. The mechanisms underlying this association remain unclear and warrant further study.

Abstract
We systematically reviewed the literature on anal human papillomavirus (HPV) infection, dysplasia, and cancer among Black and White men who have sex with men (MSM) to determine if a racial disparity exists. We searched 4 databases for articles up to March 2014. Studies involving Black MSM are nearly absent from the literature. Of 25 eligible studies, 2 stratified by race and sexual behavior. Both reported an elevated rate of abnormal anal outcomes among Black MSM. White MSM had a 1.3 times lower prevalence of group-2 HPV (P < .01) and nearly 13% lower prevalence of anal dysplasia than did Black MSM. We were unable to determine factors driving the absence of Black MSM in this research and whether disparities in clinical care exist. Elevated rates of abnormal anal cytology among Black MSM in 2 studies indicate a need for future research in this population.

Abstract
HIV infection is one of the strongest risk factors for anal squamous cell cancer (ASCC). Most ASCC are caused by HPV, and most HPV-associated ASCC are caused by HPV-16. Anal HPV infections are very common in men who have sex with men (MSM), and nearly universal among HIV-infected MSM. High-grade anal intraepithelial neoplasia (HGAIN), the precursor for ASCC, is present in about 30 % of HIV+ MSM, but neither the progression rate to ASCC nor the regression rate are known. The incidence rate of ASCC among HIV-infected people has risen in the first decade after cART became available, but appears to be plateauing recently. Anal cytology has poor sensitivity and specificity. High resolution anoscopy (HRA) is advocated by some as a screening tool in high-risk groups, but is cumbersome and time-consuming and it is unknown whether HRA followed by treatment of HGAIN prevents ASCC. More research is needed on progression and regression rates of HGAIN, on effective therapy of HGAIN, and on biomarkers that predict HGAIN or anal cancer. HPV vaccination and earlier start of cART may prevent most anal cancers in the long run.

Abstract
Background Although anal high-risk human papillomavirus (HR-HPV) infection and anal cytological abnormalities are highly prevalent among human immunodeficiency virus (HIV)-infected men who have sex with men (MSM), there are insufficient data on these abnormalities among HIV-infected heterosexual men (HSM) and women. In this study, we evaluated the prevalence of anal HR-HPV, cytological abnormalities, and performance of these screening tests in detecting high-grade anal intraepithelial neoplasia (AIN2+) among our cohort of HIV-infected MSM and non-MSM (HSM and women). Methods A single-center, retrospective cohort study was conducted with HIV-infected individuals who underwent anal cancer screening with anal cytology and HR-HPV testing from January 2011 to January 31, 2013. Results Screening of 221 HIV-infected individuals for both HR-HPV and anal cytology showed the presence of HR-HPV in 54% (abnormal anal cytology 48%) of MSM, 28% (abnormal anal cytology 28%) of HSM, and 27% (abnormal anal cytology 34%) of women. Among 117 (53%) individuals with abnormal results (HR-HPV-positive and/or cytology was atypical squamous cells of undetermined significance or above), 67 underwent high resolution anoscopy. Of these 67 individuals, 22 individuals had AIN2+ (17 MSM, four women, and one HSM). HR-HPV correlated better with AIN2+ than with anal cytology on biopsy in both MSM (r=0.29 versus r=0.10; P=0.05 versus P=0.49) and non-MSM (r=0.36 versus r=−0.34; P=0.08 versus P=0.09). Conclusion Given the presence of AIN2+ in screened HIV-infected HSM and women, routine anal cancer screening in all HIV-infected individuals should be considered. HR-HPV merits further evaluation for anal cancer screening among non-MSM.
