Abstract
BACKGROUND Human papillomavirus (HPV) is associated with cancer. Female sex workers (FSWs) are known to be at risk for HPV, but little is known about male sex workers (MSWs). METHODS We examined HPV prevalence and associated risk factors in both populations. During 2022, HPV testing using vaginal or penile samples, HIV testing, and interviews were performed among 100 MSWs and 100 FSWs in Chiang Mai, Thailand. RESULTS The prevalence of all HPV types was 63.5% (66% in MSW, 61% in FSW), HPV-16 prevalence was 14%, HPV-52 was 13%, and HPV-18 was 4%. There was no difference between MSW and FSW for these subtypes. The prevalence of HPV-16 or HPV-18 was 17%, and for HPV-16, HPV-18, or HPV-52, it was 26%. HIV-positive participants had a higher prevalence of all HPV types (94% vs. 60%, P = 0.004), HPV-16 or HPV-18 (39% vs. 15%, P = 0.018), and HPV-16, HPV-18, or HPV-52 (50% vs. 23%, P = 0.017). CONCLUSIONS We demonstrated an equally high HPV prevalence across the sexes. Further studies are needed to determine if this indicates an equal risk for cancer. Increased HPV awareness, screening, and vaccination should be considered, regardless of gender.

Abstract
Recurrent respiratory papillomatosis (RRP) is a rare manifestation of human papillomavirus (HPV) infection. It is characterized by relapsing bulky papillomas in the respiratory tract, which are usually benign in nature. We describe a challenging case of RRP in an HIV-infected patient with extensive pulmonary disease, presenting with worsening dyspnea. The interaction between HPV with HIV as a coinfection is still not completely understood, particularly the role of HIV-associated immunosuppression in RRP. Our main goal is to raise awareness of this clinical entity and to promote further studies on its management, particularly in specific populations such as HIV-infected individuals. A brief review of the theme is also presented.

Abstract
BACKGROUND Multiple anal human papillomavirus (HPVs) may increase the risk of anal cancer among men who have sex with men (MSM) living with human immunodeficiency virus (HIV). The Jaccard Similarity Index (JSI) was explored as a measure of multiple HPV persistence. METHODS The TRUST/RV368 cohort enrolled MSM living with and without HIV in Abuja and Lagos, Nigeria. Participants with anal swabs at baseline, 3- and 12-month visits were tested for high- and low-risk HPVs using a next-generation sequencing assay. Persistence of the same HPV genotypes over time was calculated using the JSI and categorized into high, medium, and low similarity tertiles. Factors associated with higher versus lower similarity were estimated with multivariable ordinal logistic regression and reported as adjusted odds ratios (aORs) and 95% confidence intervals (CIs). RESULTS Of the 225 participants, median age was 25 years (interquartile range, 22-29 years), 62% were living with HIV, median HPVs was 3 (interquartile range, 2-5), and HPV6 (28%), HPV16 (26%), HPV11 (23%), and HPV45 (20%) were most prevalent. Fifty-three percent of participants had highly similar HPVs at 3 months, and the similarity was associated with HIV (aOR, 3.11; 95% CI, 1.6-5.9) and recent receptive sex (aOR, 1.9; 95% CI, 1.0-3.5). By 12 months, 20% had highly similar HPVs, and it was associated with 12 years or longer since anal coital debut (aOR, 6.8; 95% CI, 3.1-5.2), self-reported genital warts (aOR, 3.1; 95% CI, 1.5-6.6), and 200 or less CD4 cells/mm3 (aOR, 13.3; 95% CI, 2.7-65.2) for those living with HIV. CONCLUSIONS Studies evaluating the JSI as a predictor of high-grade intraepithelial lesions would further confirm its applicability as a quantitative measure of multiple HPV persistence.

Giant anogenital tumor of Buschke-Löwenstein in a patient living with human immunodeficiency virus/acquired immunodeficiency syndrome: a case report. J Med Case Rep 2022; 16:116. [PMID: 35303943 PMCID: PMC8932054 DOI: 10.1186/s13256-022-03339-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2020] [Accepted: 02/18/2022] [Indexed: 08/29/2023] Open
Abstract
Background Buschke–Löwenstein tumor is a giant condyloma acuminata infection that is characterized by degeneration, invasion, and recurrence. It is associated with human papilloma virus infection. It develops around the genital and perineal area, sometimes causing a large budding ulcerated lesion. Although human immunodeficiency virus infection is frequent in Africa, there are few descriptions of Buschke–Löwenstein tumor diagnosis and its management. Screening for other sexually transmitted infections must be systematic among these patients. Case presentation We report herein the case of a 21-year-old African origin male patient who developed a perineal swelling. Physical examination showed evidence of a huge exophytic tumor made up of budding pinkish vegetations, with serrated crests, a ‘’butterfly wing’’ structure, and a cauliflower-like appearance crowned with centrifugal circinate lesions. Multiple condylomatous lesions of the anal margin were also present. The patient tested positive for human immunodeficiency virus (cluster of differentiation 4 count of 119 cells/mm3) and hepatitis B infections. Real-time polymerase chain reaction revealed human papilloma virus-16 and other high-risk human papilloma virus deoxyribonucleic acid. The diagnosis of Buschke–Löwenstein tumor was made on mass biopsy, and the patient underwent multidisciplinary intervention (surgery, podophyllin application, and antiretroviral therapy). Medium-term evolution was, however, fatal due to opportunistic infection. Conclusion Buschke–Löwenstein tumor is a rare tumor associated with human immunodeficiency virus infection. It is more frequent in male human immunodeficiency virus-positive patients. There is a need to screen for other sexually transmitted infections. In most cases, the treatment is surgical, in association with local therapies. However, recurrences are common.

Abstract
Objectives This study aims to investigate the association between CD4+ T cell count and combined antiretroviral therapy (cART) with the prevalence of anal human papillomavirus (HPV) infection among HIV-positive male cohort in China. Methods A survey was conducted in men from a HIV cohort in Taizhou, China between 2016 and 2019. A face-to-face questionnaire interview was administered, and an anal-canal swab was collected for HPV genotyping. Results A total of 766 HIV-positive men were recruited. The HPV prevalence was lower among those with increased CD4+ T cell count than those with decreased or unchanged (46.5 vs. 56.6%, p = 0.033) from baseline. In multivariable models, having the current CD4+ T cell count of 350–499 cells/µL (aOR 0.28, 95% CI 0.13–0.64), and of ≥ 500 cells/µL (aOR 0.26, 95% CI 0.11–0.60) were associated with lower prevalence of any type HPV infection compared with those with < 200 cells/µL. Having taken NVP + 3TC + AZT was inversely associated with any high-risk (HR)-HPV (aOR 0.47, 95% CI 0.25–0.90) and any low-risk (LR)-HPV infection (aOR 0.40, 95% CI 0.18–0.88), compared with those taking EFV + 3TC + TDF. Conclusions Increased CD4+ T cell count at follow-up was significantly associated with lower prevalence of anal HPV infection. Inverse associations between NVP + 3TC + AZT and HR-HPV or LR-HPV infecton were observed.

Abstract
HIV-infected men who have sex with men (MSM) display the highest prevalence of anal infection by high-risk Human Papillomaviruses (hrHPVs) and incidence of anal carcinoma. Anal specimens were genotyped by the Linear Array. Incidence and clearance of anal infection by hrHPVs, hrHPVs other than HPV16, low-risk HPVs, and four individual types (6,11,16,18) were estimated using a two-state Markov model. Determinants for incidence and clearance were assessed by logistic regression. Overall, 204 individuals were included (median age 42 years, IQR = 34-49). For hrHPVs, incidence and clearance rates were 36.1 × 1000 person-months (p-m) (95% CI 23.3-56.5) and 15.6 × 1000 p-m (95% CI 10.7-23.3), respectively. HPV16 showed a higher incidence than HPV18 (10.2 vs. 7.2 × 1000 p-m). Its clearance was more than twofold lower than that of HPV18 (30.1 vs. 78.2 × 1000 p-m). MSM receiving cART displayed a 68% to 88% decrease in risk of acquiring hrHPVs, hrHPVs other than HPV16, HPV16, and HPV18 (adjusted Hazard Ratio [aHR] 0.13, 95% CI 0.02-0.67; aHR 0.22, 95% CI 0.06-0.78; aHR 0.32, 95% CI 0.12-0.90; aHR 0.12, 95% CI 0.04-0.31, respectively) than patients not treated. A nadir CD4 + count < 200 cells/mm3 significantly reduced the clearance of hrHPVs other than HPV16 (aHR 0.39, 95% CI 0.17-0.90). cART use reduces the risk of acquiring anal infection by hrHPVs.

Anal human papillomavirus infection among men who have sex with men and transgender women living with and without HIV in Pakistan: findings from a cross-sectional study. BMJ Open 2021; 11:e052176.

Abstract
OBJECTIVES The aim of this study was to determine the prevalence of infection, genotypes and risk factors for human papillomavirus (HPV) among men who have sex with men (MSM) and transgender women living with and without HIV in Pakistan. Anal infection with HPV is very common worldwide among MSM, particularly among MSM living with HIV. The high prevalence of HIV among MSM and male-to-female transgendered individuals in Pakistan is a significant health concern since access to screening and health-seeking is often delayed in this stigmatised key population. DESIGN This cross-sectional study was conducted between March 2016 and November 2017. PARTICIPANTS, SETTING AND DATA COLLECTION This study recruited MSM and transgender-women who self-reported to have had anal sex in the last 6 months, and were at least 18 years of age, from the sexual health and antiretroviral therapy centres. Structured questionnaires were administered, and blood samples were obtained to confirm HIV status. Anal swabs were collected for HPV-DNA detection and typing. MAIN OUTCOME MEASURES The primary outcome was the prevalence of 'HPV-DNA infection'. The prevalence ratios (PR) were calculated using Cox proportional hazard model algorithms to analyse the association between exposure variables and HPV-infection. RESULTS Complete data were available for 298 MSM and transgender women (HIV +n=131; HIV-n=167). The overall HPV-DNA prevalence was 65.1% and was higher in participants living with HIV as compared with HIV-negative (87% vs 48%; χ2p≤0.001). Likewise, 28.9% of participants living with HIV were infected with two or more than two types of HPV as compared with 18.8% participants without HIV(χ2 p≤0.001). The most frequent HPV type was HPV6/11 (46.9%), followed by HPV16 (35.1%), HPV18 (23.2%) and HPV35 (21.1%). HIV status (PR 2.81, 95% CI 2.16 to 3.82) and never condom use (PR 3.08, 95% CI 1.69 to 5.60)) were independently associated with prevalence of 'anal-HPV16 infection' when adjusting for confounding for age, other sexual and behavioural factors, for example, smoking and alcohol consumption. CONCLUSION High prevalence of HPV indicates a substantial future risk of anal cancer in Pakistani MSM and transgender women, and particularly in those living with HIV. Current findings support anal Pap-smear HPV screening for this particular group and vaccination efforts for future generations.

Lancet HIV 2021; 8:e531-e543. [PMID: 34339628 PMCID: PMC8408042 DOI: 10.1016/s2352-3018(21)00108-9] [Citation(s) in RCA: 82] [Impact Index Per Article: 27.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2021] [Revised: 04/29/2021] [Accepted: 05/18/2021] [Indexed: 12/18/2022]
Abstract
BACKGROUND Robust age-specific estimates of anal human papillomavirus (HPV) and high-grade squamous intraepithelial lesions (HSIL) in men can inform anal cancer prevention efforts. We aimed to evaluate the age-specific prevalence of anal HPV, HSIL, and their combination, in men, stratified by HIV status and sexuality. METHODS We did a systematic review for studies on anal HPV infection in men and a pooled analysis of individual-level data from eligible studies across four groups: HIV-positive men who have sex with men (MSM), HIV-negative MSM, HIV-positive men who have sex with women (MSW), and HIV-negative MSW. Studies were required to inform on type-specific HPV infection (at least HPV16), detected by use of a PCR-based test from anal swabs, HIV status, sexuality (MSM, including those who have sex with men only or also with women, or MSW), and age. Authors of eligible studies with a sample size of 200 participants or more were invited to share deidentified individual-level data on the above four variables. Authors of studies including 40 or more HIV-positive MSW or 40 or more men from Africa (irrespective of HIV status and sexuality) were also invited to share these data. Pooled estimates of anal high-risk HPV (HR-HPV, including HPV16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, and 68), and HSIL or worse (HSIL+), were compared by use of adjusted prevalence ratios (aPRs) from generalised linear models. FINDINGS The systematic review identified 93 eligible studies, of which 64 contributed data on 29 900 men to the pooled analysis. Among HIV-negative MSW anal HPV16 prevalence was 1·8% (91 of 5190) and HR-HPV prevalence was 6·9% (345 of 5003); among HIV-positive MSW the prevalences were 8·7% (59 of 682) and 26·9% (179 of 666); among HIV-negative MSM they were 13·7% (1455 of 10 617) and 41·2% (3798 of 9215), and among HIV-positive MSM 28·5% (3819 of 13 411) and 74·3% (8765 of 11 803). In HIV-positive MSM, HPV16 prevalence was 5·6% (two of 36) among those age 15-18 years and 28·8% (141 of 490) among those age 23-24 years (ptrend=0·0091); prevalence was 31·7% (1057 of 3337) among those age 25-34 years and 22·8% (451 of 1979) among those age 55 and older (ptrend<0·0001). HPV16 prevalence in HIV-negative MSM was 6·7% (15 of 223) among those age 15-18 and 13·9% (166 of 1192) among those age 23-24 years (ptrend=0·0076); the prevalence plateaued thereafter (ptrend=0·72). Similar age-specific patterns were observed for HR-HPV. No significant differences for HPV16 or HR-HPV were found by age for either HIV-positive or HIV-negative MSW. HSIL+ detection ranged from 7·5% (12 of 160) to 54·5% (61 of 112) in HIV-positive MSM; after adjustment for heterogeneity, HIV was a significant predictor of HSIL+ (aPR 1·54, 95% CI 1·36-1·73), HPV16-positive HSIL+ (1·66, 1·36-2·03), and HSIL+ in HPV16-positive MSM (1·19, 1·04-1·37). Among HPV16-positive MSM, HSIL+ prevalence increased with age. INTERPRETATION High anal HPV prevalence among young HIV-positive and HIV-negative MSM highlights the benefits of gender-neutral HPV vaccination before sexual activity over catch-up vaccination. HIV-positive MSM are a priority for anal cancer screening research and initiatives targeting HPV16-positive HSIL+. FUNDING International Agency for Research on Cancer.

Rectal Douching and Anal Human Papillomavirus Among Young Men Who Have Sex With Men in China. Sex Transm Dis 2021; 48:550-556. [PMID: 34110748 DOI: 10.1097/olq.0000000000001392] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/26/2022]
Abstract
BACKGROUND Young men who have sex with men (YMSM) are particularly at increased risk for human papillomavirus (HPV) infection and related malignancies. Rectal douching, commonly practiced among MSM, has been associated with HIV, chlamydia, gonorrhea, and viral hepatitis in cross-sectional studies. We conducted this study to understand the association between self-reported rectal douching and anal HPV among YMSM in China. METHODS Between September 2018 and March 2019, MSM aged 15 to 24 years who ever engaged in receptive anal intercourse over the last 3 months were recruited via community-based organizations and centers for disease control located in 4 cities in China. Participants were asked to complete an online survey. We performed multivariate logistic regression adjusted for potential confounders to examine the association between self-reported rectal douching and anal HPV. RESULTS Among 273 MSM with a median age of 20 years (interquartile range, 19-21 years) included in this study, 130 (47.6%) practiced rectal douching during the preceding 3 months and 96 (36.2%) were infected with anal HPV. Self-reported rectal douching was found to be associated with increased odds of anal HPV infection (odds ratio, 2.16; 95% confidence interval, 1.22-3.82) among YMSM, after adjusting for age, sexual debut, sex with alcohol or drugs, and HIV testing history. CONCLUSIONS Self-reported rectal douching is associated with higher odds of anal HPV infection independent of sexual behaviors among YMSM. More prospective studies to ascertain this association are needed. Health education materials should inform men of the potential risk of rectal douching. Research on safer rectal douching procedures is warranted.

Abstract
BACKGROUND Incidence of anal cancer is highest in gay and bisexual men (GBM). Better understanding of the natural history of anal high-risk human papillomavirus (hrHPV) infection is needed for anal cancer prevention. METHODS The Study of the Prevention of Anal Cancer was a 3-year study of Australian GBM, aged 35 years or older. We examined incidence, clearance, and risk factors for 13 hrHPV types at baseline and 3 annual visits. RESULTS In 525 men with ≥ 2 visits, 348 (66.3%) acquired ≥ 1 incident hrHPV infection. HPV16 incidence rates were similar, but non-16 hrHPV incidence was higher in HIV-positive (51.8/100 person years [PY]) than HIV-negative men (36.5/100 PY, P < .001). Annual clearance rates of HPV16 (13.21/100 PY, 95% confidence interval, 10.53-16.56) were lower than for other hrHPV types. hrHPV clearance rates were not associated with HIV overall but were significantly lower in those with a lower nadir CD4 (<200 cells/µL) for HPV16 (P = .015) and other hrHPV types (P = .007). CONCLUSIONS Higher incidence of non-16 hrHPV types, coupled with lower clearance of non-16 hrHPV types in those with past impaired immune function, is consistent with the greater role of non-16 hrHPV in anal cancer in HIV-positive people.

Abstract
OBJECTIVE To estimate the prevalence of high-risk human papillomavirus (HR-HPV) anal infection and associated factors in human immunodeficiency virus (HIV) positive patients in Medellín. METHODS Descriptive cross-sectional study in 300 HIV-positive patients, adults, with history of anal intercourse, treated in two health care services of Medellín 2017–2018. We conducted a structured survey on sociodemographics, sexual behavior and medical history. HPV was detected in anal swabs tested by the COBAS 4800 system. Exploratory data analysis of risk factors associated with HR-HPV was conducted by chi-square test of independence and both raw and adjusted prevalence ratios used the Poisson regression model, at a 95% confidence interval. RESULTS The high-risk HPV had a prevalence of 82.7%; HPV16 had a prevalence of 32.7%, HPV18 a prevalence of 21.7% and other HPV types scored 78.3%. The high-risk HPV prevalence in women was of 68.2% and 83.8% in men. The risk factors associated with high-risk HPV after adjustment were age under 30 years, elementary education, casual sex partners, and first sexual activity before 18 years old. CONCLUSIONS The high incidence of high-risk HPV, along with the occurrence of coinfections by multiple types in the study population shows their susceptibility to develop some type of anal intra-epithelial neoplasia. It is important to establish sexual health programs focused on primary health care.

Abstract
This study aims to investigate the prevalence and genotype distribution of anal human papillomavirus (HPV) infection among men with different sexual orientations with or without human immunodeficiency virus (HIV) in China. A cross-sectional study was conducted during 2016-2017 in Taizhou City, Zhejiang Province. Convenient sampling was used to recruit male participants from HIV voluntary counselling and testing clinics and Center for Disease Control and Prevention. A face-to-face questionnaire interview was administered and an anal-canal swab was collected for HPV genotyping. A total of 160 HIV-positive and 113 HIV-negative men participated in the study. The prevalence of any type HPV was 30.6% for heterosexual men, 74.1% for homosexual and 63.6% for bisexual men among HIV-positive participants, while the prevalence was 8.3%, 29.2% and 23.8% respectively among HIV-negatives. The most prevalent genotypes were HPV-58 (16.9%), HPV-6 (15.6%) and HPV-11 (15.0%) among HIV-positive men, and were HPV-16 (4.4%), HPV-52 (4.4%) and HPV-6 (3.5%) among HIV-negative men. Having ever had haemorrhoids and having ever seen blood on tissue after defaecation was associated with HPV infection. One-fourth of the HPV infections in this study population can be covered by the quadrivalent vaccine in market. The highly prevalent anal HPV infection among men especially HIV-infected men calls for close observation and further investigation for anal cancer prevention.

Abstract
Human papillomavirus (HPV) infection contributes to most anal cancers and premalignant intraepithelial lesions. This study investigated anal HPV infections and cytological abnormalities among men who have sex with men (MSM). Sociodemographic characteristics and sexual behaviors were collected by using a structured questionnaire. Anal cytological results were examined, and HPV genotyping was performed by the Linear Array HPV Genotyping test. Logistic regression was used to estimate risk factors and their associations with high-risk HPV infection and cytological abnormalities. Among 163 MSM, 101 were seropositive for human immunodeficiency virus (HIV) and 62 were seronegative for HIV. The overall prevalence of HPV was 66.2%. A total of 61.9% and 48.2% of participants had never acquired any of either the quadrivalent or nonavalent vaccine HPV types, respectively. Cytological findings showed 15.3% atypical squamous cells of undetermined significance, 16.6% low-grade squamous intraepithelial lesion, 4.9% atypical squamous cells that cannot exclude high-grade squamous intraepithelial lesion and 17% high-grade squamous intraepithelial lesion. The number of high-risk HPV types was the predominant risk factor for abnormal anal cytology (OR 2.02, 95% CI 1.27–3.24). Infection with high-risk HPV was a significant predictor for cytological abnormality. MSM should be encouraged to obtain the HPV vaccine.

Abstract
BACKGROUND Electrocautery ablation (EA) is a common treatment modality for patients with anal high-grade squamous intraepithelial lesions (HSILs), but to the authors' knowledge its effectiveness has been understudied. The objective of the current study was to determine ablation outcomes and to identify clinicopathological factors associated with postablation disease recurrence. METHODS A total of 330 people living with HIV with de novo intra-anal HSIL who were treated with EA from 2009 to 2016 were studied retrospectively. Using long-term, surveillance high-resolution anoscopy biopsy data, treatment failures were classified as local recurrence (HSIL noted at the treated site at the time of surveillance) or overall recurrence (HSIL noted at treated or untreated sites). The associations between these outcomes and clinical factors were analyzed using Cox proportional hazards models. RESULTS Approximately 88% of participants were men who have sex with men. The median age of study participants was 45.5 years (range, 35-51 years) and approximately 49% had multiple index HSILs (range, 2-6 index HSILs). At a median of 12.2 months postablation (range, 6.3-20.9 months postablation), approximately 45% of participants had developed local recurrence whereas 60% had developed overall recurrence. Current cigarette smoking, HIV viremia (HIV-1 RNA ≥100 copies/mL), and multiple index HSILs were found to be predictive of local recurrence. Overall recurrence was more common in current smokers and those with multiple index lesions. In multivariable models that included human papillomavirus (HPV) genotypes, baseline and persistent infections with HPV-16 and/or HPV-18 were found to be significantly associated with both local and overall recurrence. CONCLUSIONS EA is an effective treatment modality for anal HSIL in people living with HIV, but rates of disease recurrence are substantial. Multiple index HSILs, HIV viremia, current cigarette smoking, and both baseline and persistent infection with HPV-16 and/or HPV-18 appear to negatively impact treatment success. Ongoing surveillance is imperative to capture recurrence early and improve long-term treatment outcomes.

Abstract
Background The natural history of anal human papilloma virus (HPV) infection among human immunodeficiency virus (HIV)-infected men is unknown. Methods Annually, from 2004 to 2012, we examined baseline prevalence, incidence, and clearance of anal HPV infection at 48 months, and associated factors among HIV-infected men. Results We examined 403 men who have sex with men (MSM) and 96 men who have sex with women (MSW) (median age 42 years for both, 78% versus 81% prescribed cART, median CD4+ T-lymphocyte cell count 454 versus 379 cells/mm3, and 74% versus 75% had undetectable viral load, respectively). Type 16 prevalence among MSM and MSW was 38% versus 14% (P < .001), and incidence 24% versus 7% (P = .001). Type 18 prevalence was 24% versus 8% (P < .001), and incidence 13% versus 4% (P = .027). Among MSM and MSW, clearance of prevalent HPV 16 and HPV 18 was 31% and 60% (P = .392), and 47% and 25% (P = .297), respectively. Among MSM, receptive anal sex (with or without a condom) was associated with persistent HPV 16 (OR 2.24, P < .001). Conclusions MSM had higher prevalence and incidence of HPV than MSW, but similar clearance. Receptive anal sex may predict cancer risk among HIV-infected MSM.

Abstract
Background Anal human papillomavirus (HPV) infection, most notably HPV16, the central cause of anal cancer, is increased by anal sexual intercourse and worsened by human immunodeficiency virus (HIV)-positivity. Methods A systematic review and meta-analysis of type-specific anal HPV prevalence in men, compared according to sexual preference, HIV status, and, when available, anal cytopathology. Results Seventy-nine eligible studies included: 1805 HIV-negative men who have sex with women (MSW), 924 HIV-positive MSW, 8213 HIV-negative men who have sex with men (MSM), and 12758 HIV-positive MSM. Irrespective of anal cytopathology, HPV16 prevalence was significantly higher in MSM than MSW, both among HIV-negative (14% vs 3%; prevalence ratio (PR) 4.7; 95% confidence interval [CI] 2.5-8.9) and HIV-positive men (30% vs 11%; PR = 2.8; 95% CI, 1.9-4.1). Likewise, HPV16 was significantly higher in HIV-positive than HIV-negative men, both among MSW (PR = 3.5; 95% CI, 1.6-7.7) and MSM (PR = 2.1; 95% CI, 1.8-2.5). Anal HPV16 prevalence was similar between HIV-positive MSW and HIV-negative MSM. For MSM, anal HPV16 prevalence was significantly higher from studies with anal cytopathology, suggesting population sampling effects. Conclusion Sexual preference and HIV infection are independent strong determinants of male anal HPV16 infection, confirming HIV-positive MSM as priorities for anal cancer prevention.

Abstract
OBJECTIVE(S) HIV-positive individuals have elevated rates of anal squamous cell carcinoma (SCC), and sexually transmitted infections with its causative agent, high-risk human papillomavirus, and other oncoviruses including hepatitis B virus (HBV). HBV infection can cause liver cancer, and has been associated with increased risk of some extra-hepatic cancers including biliary tract cancer, pancreatic cancer, and non-Hodgkin lymphoma. Whether HBV is associated with anal SCC risk is unknown. DESIGN Prospective study of anal SCC risk in HIV-positive and HIV-negative MSM in the Multicenter AIDS Cohort Study from 1984 to 2014. METHODS Poisson regression models were used to examine the association between past or current HBV infection (positive tests for HBV core antibodies, surface antigen, and/or DNA) and anal SCC risk. RESULTS We observed 53 cases of anal SCC among 5298 participants with 79 334 person-years follow-up. Among HIV-positive men, past or current HBV infection was associated with anal SCC risk in models adjusted for age, CD4+ cell counts, HAART use, and other risk factors [incidence rate ratio (IRR), 95% confidence interval 3.15, 1.27-7.82]. Additional risk factors included immunological parameters 1 and 6 years prior to diagnosis (IRR, 95% confidence interval 2.45, 1.31-4.58 and 2.44, 1.3-4.59 for CD4+ cell counts <500 cells/μl; 2.43, 1.34-4.42 and 2.77, 1.5-5.11 for CD4+ : CD8+ ratios <0.5, respectively). Among HIV-negative men, IRR for prior HBV and anal SCC risk was similar, but NS due to small number of cases. CONCLUSION HIV-positive MSM with prior HBV infection have increased anal SCC risk. This population may benefit from screening.

Human papillomavirus (HPV) infection is associated with cancer and can be prevented through vaccination. Few studies from Taiwan have reported on HPV infection among human immunodeficiency virus (HIV)-infected subjects. The aim of this study was to examine the prevalence of HPV infection among men who have sex with men (MSM) with and without HIV infection in Taiwan, and explore the behavioral risk factors thereof.We conducted a cross-sectional study in Taiwan during 2013 to 2016 to collect data on MSM aged 20 years or older. We used a questionnaire in a face-to-face interview, and subsequently collected oral, anal, and genital specimens from HIV-infected and HIV-uninfected subjects. Multivariate analysis was performed to predict factors associated with high-risk HPV (HR-HPV) positivity.Overall, 279 subjects, including 166 (59.5%) HIV-uninfected and 113 (40.5%) HIV-infected men were enrolled. Compared to HPV-negative subjects, HPV-positive subjects had significantly higher rates of receptive anal sex (91.3% vs 75.6%), substance use (22.6% vs 11%), history of sexually transmitted infections (75.7% vs 38.4%), anogenital or oral warts (39.1% vs 6.72%), syphilis (32.2% vs 11.6%), and HIV infection (69.6% vs 20.1%). We detected 489 HPV deoxyribonucleic acid (DNA) types (through 379 viable specimens), of which 43.6%, 5.7%, 56.4%, and 10.4% were HR-HPV type, HPV type 16, low-risk HPV types, and HPV type 6, respectively. In multivariate analysis, HIV-infected subjects had a significantly higher prevalence of HR-HPV infection (adjusted odds ratio, 5.80; 95% confidence interval, 2.57-13.11), compared to HIV-uninfected subjects.These results suggest that the prevalence of HPV infection was high among HIV-infected MSM. Additionally, anal HPV infection was observed to be common among both HIV-infected and HIV-uninfected MSM in Taiwan. The prevalence of oral and genital HPV infection, HR-HPV DNA types, and multiple HPV types was higher in HIV-infected subjects than in HIV-uninfected subjects. As only 35% of subjects practiced safe sex, we recommend routine HPV vaccination with 4-valent HPV or 9-valent HPV vaccines for both MSM, and HIV-infected subjects.

Evidence of synergistic relationships between HIV and Human Papillomavirus (HPV): systematic reviews and meta-analyses of longitudinal studies of HPV acquisition and clearance by HIV status, and of HIV acquisition by HPV status. J Int AIDS Soc 2018; 21:e25110. [PMID: 29873885 PMCID: PMC5989783 DOI: 10.1002/jia2.25110] [Citation(s) in RCA: 92] [Impact Index Per Article: 15.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2017] [Accepted: 03/27/2018] [Indexed: 12/17/2022] Open
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 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 Anal high-grade squamous intraepithelial lesions (HSILs) are the precursors to anal cancer and frequently persist or recur following electrocautery ablation (EA). Impaired mucosal immunity may facilitate anal carcinogenesis. We characterized the immune microenvironment of anal HSILs in correlation with human immunodeficiency virus (HIV) serostatus and ablation outcomes. Methods Using immunohistochemistry, mucosa-infiltrating CD4+ and CD8+ lymphocytes were quantified in HSILs and benign mucosa from 70 HIV+ and 45 HIV- patients. Clinicopathological parameters were compared. Results Anal HSILs harbored more T lymphocytes than benign mucosa regardless of HIV status (P ≤ .03). Total T lymphocyte count and CD8+ subset were significantly higher in HIV+ HSILs versus HIV- HSILs (median cell count, 71 vs 47; 47 vs 22/high power field [HPF]; P < .001), whereas the CD4+ subset was comparable between groups (median, 24 vs. 25; P = .40). Post EA, HSILs persisted in 41% of HIV+ and 19% of HIV- patients (P = .04). Unadjusted analysis showed trends toward EA failures associated with HIV seropositivity (incidence rate ratio [IRR], 2.0; 95% CI, .8-4.9) and increased CD8+ cells (IRR, 2.3; 95% CI, .9-5.3). Conclusions Human immunodeficiency virus is associated with alterations of the immune microenvironment of anal HSILs manifested by increased local lymphocytic infiltrates, predominately CD8+. Human immunodeficiency virus seropositivity and excess mucosa-infiltrating CD8+ cells may be associated with ablation resistance.

Functional characterization of CD4 and CD8 T cell responses among human papillomavirus infected patients with ano-genital warts. Virusdisease 2017; 28:133-140. [PMID: 28770238 DOI: 10.1007/s13337-017-0382-8] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2017] [Accepted: 05/09/2017] [Indexed: 10/19/2022] Open
Abstract
Ano-genital warts are considered one of the commonest and highly infectious sexually transmitted infections. These warts are primarily caused by the human papillomavirus (HPV) of the family Papillomaviridae, genus alpha-papillomavirus, species 10 and types 6 and 11. However the high recurrence rate of warts is a matter of serious concern to the patients and a challenge for the treating physician. The conventional treatment options are targeted only to the local site of warts. There is no systemic treatment modality as there is limited understanding of the disease immune-pathogenesis. The role of cell-mediated immunity in combating HPV infection is not clearly defined. Hence the present study is aimed at investigating the CD4+ T helper (Th1 and Th2) and CD8+ T cell responses among wart patients. In this study, we compared HPV6 and HPV11 antigen-specific T cell responses among venereal wart patients relative to healthy controls. Significant decrease in percent frequencies of IFN-γ producing CD4+ and CD8+ T cells were observed in HPV infected wart patients. On the other hand, the frequency of CD4+ T cells expressing IL-4 was significantly increased in these patients as compared to healthy controls. The observed functional skewing of HPV specific T cells from Th1 to Th2 response in patients indicated suppressed immunity against the HPV. Moreover, decrease in CD8 T cell function correlated with poor wart clearance. Our findings open future avenues for exploring potential immunomodulation strategies as an adjunct to standard treatment for better management of these patients and prevention of recurrence.

Abstract
OBJECTIVE To evaluate HIV-related and other clinical risk factors associated with oropharynx cancer (OPSCC) in HIV-infected U.S. Veterans. METHODS Retrospective cohort study utilizing Veterans Affairs HIV Clinical Case Registry (CCR) data from 1985 to 2010. Outcome was incident OPSCC as indicated by 1 inpatient or 2 outpatient ICD-9 codes. Cox proportional hazard models were used to determine hazard ratios (HR) and 95% confidence intervals (CI) for each risk factor on the time to OPSCC diagnosis. RESULTS A total of 40,996 HIV-infected male veterans were included in the cohort with 97 cases of OPSCC. The age adjusted incidence rate was 23.2/100,000 [95% CI 17.8-29.2]. Age>50 (aHR=3.8, 95% CI 1.9-7.8), recent CD4<200 (aHR=3.8, 95% CI 2.0-7.3), and undetectable HIV viral loads 40-79% of the time (aHR=1.8, 95% CI 1.1-3.0) were associated with an increased risk of OPSCC. Era of HIV diagnosis, utilization of cART, nadir CD4 count, race, smoking history, and previous risk of HPV disease, including condyloma or invasive squamous cell carcinoma of the anus (SCCA) were not associated with increased risk of OPSCC. CONCLUSION Patients who were older at beginning of follow up, had lower CD4 counts around the time of OPSCC diagnosis, and moderate HIV viral control during follow-up had an increased risk of OPSCC. Other HPV-related diseases such as SCCA and condyloma did not increase the risk for OPSCC.

Abstract
Human papillomavirus (HPV) infection is mostly asymptomatic, but may also have many diverse clinical signs encompassing benign ano-genital lesions, and carcinomas. Recently, interest has also particularly focused on anal cancer since, over the last decades, its incidence has been greatly increasing in developed countries, both in women and men and is drastically higher in specific risk groups, such as men who have sex with men (MSM) and HIV-1 infected individuals. Approximately 88% of anal cancer cases worldwide are associated with HPV infection. This review summarizes our current understanding of anal HPV infection, discussing its epidemiology and risk factors in various populations, and the state of the art in the detection of anal HPV infection and its related lesions through both cytology and histology. Finally, we discuss the clinical management and therapy for these lesions.

Abstract
Little is known regarding the natural history of anal human papillomavirus (HPV) infection. We aimed to evaluate incidence and clearance rates, their risk factors, and duration of anal HPV infection in HIV-uninfected men who have sex with men (MSM). A longitudinal study was conducted. Anal samples were analysed using the Linear Array HPV Genotyping test. Incidence and clearance rates, and corresponding risk factors, were estimated using a two-state Markov model. Overall, 155 MSM (median age 33.4 years) attending the largest sexually transmitted infection (STI) centre in Rome, Italy, were followed for a median of 12.2 months (Q1-Q3: 7.0-18.1). Incidence and clearance rates for any HPV were 85.6 (95% CI: 58.4-125.4) and 35.6 (95% CI: 24.7-51.5) × 1000 person-months, respectively; the median duration of infection was 9.4 months (Q1-Q3: 7.5-12.1). Receptive anal sex emerged as the only risk factor for the acquisition of any HPV (Hazard Ratio, HR = 2.65, 95% CI: 1.16-6.06). The incidence rates for carcinogenic and non-carcinogenic types were 42.3 (95% CI: 29.2-61.4) and 29.2 (95% CI: 19.5-43.7) × 1000 person-months, respectively (p = 0.13); their clearance rates were 62.9 (95% CI: 45.1-87.7) and 65.7 (95% CI: 47.4-91.0) × 1000 person-months, respectively (p = 0.83). HPV16 showed the lowest clearance rate among carcinogenic types (59.7 × 1000 person-months), and a duration of infection of 16.8 months. In conclusion, a higher incidence rate was observed for carcinogenic compared to non-carcinogenic HPV types, although the difference was not significant. HPV16 emerged as the type with the longest duration of infection and the lowest clearance rate among carcinogenic types.

Abstract
BACKGROUND Little is known about the epidemiology on human papillomavirus (HPV) infection among HIV-infected men in Korea. The objective of this study was to determine the prevalence, genotype distribution and risk factors associated with anal HPV infection among HIV-infected men in Korea. METHODS A single-center cross-sectional study was conducted with HIV-infected men in Korea. Participants completed a detailed sexual behavior risk factor questionnaire. Anal samples were collected for cytology and HPV genotyping. Factors associated with anal HPV infection were assessed using multivariable logistic regression, stratifying by sexual behaviour. RESULTS A total of 201 HIV-infected men were included in the study: 133 were from men who have sex with men (MSM) and 68 from men who have sex with women (MSW). Any anal HPV infection was detected in 82.7% of HIV-infected MSM and in 51.5% of HIV- infected MSW (P < 0.001). High-risk HPV (HR-HPV) prevalence was higher among MSM (47.4%) than MSW (25.0%; P = 0.002). The HR-HPV types identified most frequently were HPV 16 (11%), HPV 18 (9.9%), and HPV 58 (5%) in MSM, and HPV 58(11%) and HPV 16 (8.9%) in MSW. Prevalence of any HPV types in 9-valent vaccine types was higher among MSM than MSW (47.4% vs 22.1%. P = 0.001). Abnormal anal cytology was more commonly detected in MSM than MSW (42.9% vs.19.1%, P < 0.001). In HIV-infected MSM, higher number of lifetime male sex partners was significantly associated with any anal HPV infection, but age was a significant risk factor associated with anal HR-HPV infection. CONCLUSION Anal HPV infection was highly prevalent in HIV-infected MSM in Korea, and also commonly found in HIV-infected MSW. In HIV-infected MSM, the significant risk factor for being infected with any HPV infection was lifetime number of male sexual partners, and with anal oncogenic HPV infection was age.

Abstract
BACKGROUND India has a large population of HIV-positive individuals, including men who have sex with men (MSM), and the incidence of human papillomavirus (HPV)-related cancers is high. In developed countries, HIV-positive MSM exhibit the highest prevalence of anal HPV infection and incidence of anal cancer. Little is known about anal HPV infection in HIV-positive Indian MSM. METHODS We evaluated 300 HIV-positive MSM from 2 cities in India. Men were tested for anal HPV infection using L1-HPV DNA polymerase chain reaction with probes specific for 29 types and a mixture of 10 additional types. CD4 level and plasma HIV viral load were measured. Participants completed an interviewer-administered questionnaire including a sexual history. RESULTS The prevalence of anal HPV was 95% (95% confidence interval: 91% to 97%). The 3 most common types were HPV 35 (20%), HPV 16 (13%), and HPV 6/11 (13%). History of taking antiretroviral medications decreased risk of anal HPV 16 infection [relative risk (RR): 0.6 (0.4-1.0)]. Having an increased number of vaginal sex partners lowered risk of any anal HPV infection. Ever having receptive sex increased risk of any anal HPV [RR: 1.2 (1.1-1.4)] and anal HPV 16 [RR: 6.5 (1.8-107)]. CONCLUSIONS Almost all Indian HIV-positive MSM had anal HPV infection. The prevalence of HPV 16 was lower and the prevalence of other oncogenic HPV types was higher than in similar populations in North America and Europe. Vaccine-based prevention strategies for HPV infection in India should consider potential differences in HPV type distribution among HIV-infected MSM when designing interventions.

Cytological Anal Squamous Intraepithelial Lesions Associated with Anal High-Risk Human Papillomavirus Infections among Men Who Have Sex with Men in Northern Thailand. PLoS One 2016; 11:e0156280. [PMID: 27227684 PMCID: PMC4882004 DOI: 10.1371/journal.pone.0156280] [Citation(s) in RCA: 21] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2015] [Accepted: 05/11/2016] [Indexed: 12/30/2022] Open
Abstract
BACKGROUND Anal cancer, one of human papillomavirus (HPV) related malignancies, has increased in recent decades, particularly among men who have sex with men (MSM) and HIV-infected (HIV+) persons. We aimed to explore the prevalence of anal squamous intraepithelial lesions (ASIL) using Papanicolau (Pap) screening among MSM in northern Thailand and its associated factors. METHODS Two hundreds MSM aged ≥18 years reporting receptive anal intercourse in the prior 6 months were recruited from July 2012 through January 2013. Medical history and behavioral data were collected by staff interview and computer-assisted self interview. Anal Pap smear, HPV genotyping, and HIV testing were performed. Two pathologists blinded to HPV and HIV status reported cytologic results by Bethesda classification. RESULTS Mean age was 27.2 years (range 18-54). Overall, 86 (43.0%) had ASIL: 28 (14.2%) with atypical cells of undetermined significance (ASCUS), 1 (0.5%) with atypical squamous cells-cannot exclude high-grade squamous intraepithelial lesion (ASC-H), 56 (28.4%) with low-grade squamous intraepithelial lesion (LSIL), and 1 (0.5%) with high-grade squamous intraepithelial lesion (HSIL). ASIL was associated by univariate analysis (p ≤0.05) with older age, gender identity other than bisexual (i.e., gay men and transgender women), rectal douching, anal symptoms, genital warts, HIV positivity, and high-risk-HPV infection. However, on multiple logistic regression ASIL was associated only with high-risk HPV type (p = 0.002) and HIV infection (p = 0.01). CONCLUSIONS ASIL is quite common in high-risk MSM in northern Thailand and is associated with high-risk HPV types and HIV infection. Routine anal Pap screening should be considered, given the high frequency of ASIL, particularly in the HIV+. High resolution anoscopy (HRA), not done here, should be to confirm PAP smears whose sensitivity and specificity are quite variable. Timely HPV vaccination should be considered for this population.

Abstract
HIV-infected individuals are at increased risk for most types of cancer, including those typically classified as non-AIDS-defining cancers (NADCs). This increased risk is likely multifactorial, but a prominent risk factor for the increased rate of some cancers is co-infection with oncogenic viruses. Anal cancer, hepatocellular carcinoma, and Hodgkin lymphoma are three of the most common NADCs, and they are associated with co-infection with human papillomavirus, hepatitis B and C, and Epstein Barr virus, respectively. This review will examine the epidemiology, pathogenesis, and future trends around these virally associated NADCs frequently found in HIV-infected individuals.

Abstract
UNLABELLED The incidences of human papillomavirus (HPV)-related anal cancer and its precursor lesion, anal intraepithelial neoplasia, are rising in the U.S. and globally. Five-year survival rates with current modalities of treatment for anal cancer are generally favorable for localized and regional disease. For metastatic disease, the relative survival rate is poor. Major contributing factors for the increase in anal cancer incidence include increasing receptive anal intercourse (hetero- and homosexual), increasing HPV infections, and longer life expectancy of treated people who are seropositive for human immunodeficiency virus. Because treatment outcomes with systemic therapy in patients with advanced disease are so poor, prevention may be the best approach for reducing disease burden. The association of a major causative agent with anal cancer provides an excellent opportunity for prevention and treatment. The advent of the HPV vaccine for anal cancer prevention and treatment is a significant milestone and has the potential to greatly impact these cancers. The data regarding potential use of the HPV vaccine in anal cancer prevention and treatment are reviewed. IMPLICATIONS FOR PRACTICE The incidences of human papillomavirus (HPV)-related anal cancer and its precursor lesion, anal intraepithelial neoplasia, are on the rise in the U.S. and globally. Based on recent studies, the HPV vaccine is approved for prevention of the infection and development of HPV-related anal cancer. In addition, several small studies have shown that the vaccine may be useful as adjuvant therapy for anal cancer. There is a need for public health strategies aimed at education of both patients and practitioners to improve the use of the vaccine for prevention of HPV-related anal cancer. The development of a therapeutic vaccine is a work in progress.

Abstract
BACKGROUND Given high rates of anal disease, we investigated the natural history of high-risk anal human papillomavirus (HPV) among a multinational group of men who have sex with men (MSM) aged 18-64 years. METHODS Anal specimens from human immunodeficiency virus-negative men from Brazil, Mexico, and the United States were genotyped. Over 2 years, 406 MSM provided evaluable specimens every 6 months for ≥2 visits. These men were stratified into men who have sex only with men (MSOM, n = 70) and men who have sex with women and men (MSWM, n = 336). Persistence was defined as ≥12 months' type-specific duration and could begin with either a prevalent or incident infection. Prevalence ratios and 95% confidence intervals were calculated by Poisson regression. RESULTS Median follow-up time was 2.1 years. Retention was 82%. Annual cumulative incidence of 9-valent vaccine types was 19% and 8% among MSOM and MSWM, respectively (log-rank P = .02). Duration of anal HPV did not differ for MSOM and MSWM and was a median of 6.9 months for HPV-16 after combining men from the 2 groups. Among men with prevalent high-risk infection (n = 106), a total of 36.8%, retained the infection for at least 24 months. For those with prevalent HPV-16 (n = 27), 29.6% were persistent for at least 24 months. Persistence of high-risk HPV was associated with number of male anal sex partners and inversely associated with number of female sex partners. CONCLUSIONS MSM with prevalent high-risk HPV infection should be considered at increased risk for nontransient infection.

Abstract
Anal health and anal cancer are rarely addressed in HIV primary care. We sought to understand factors that impeded or promoted addressing anal health in HIV primary care from providers' perspectives. In this exploratory study, HIV primary care providers from the Mid-South region of the United States participated in brief individual interviews. We analyzed transcribed data to identify barriers and facilitators to addressing anal health. Our study sample included five physicians and four nurse practitioners. The data revealed a number of barriers such as perception of patient embarrassment, provider embarrassment, external issues such as time constraints, demand of other priorities, lack of anal complaints, lack of resources, and gender discordance. Facilitators included awareness, advantageous circumstances, and the patient-provider relationship. Anal health education should be prioritized for HIV primary care providers. Preventive health visits should be considered to mitigate time constraints, demands for other priorities, and unequal gender opportunities.

Abstract
Anal human papillomavirus (HPV) infection, which is linked to anal warts and anal cancer, is common among men who have sex with men (MSM), especially among those HIV positives. MSM aged 18 years or older were recruited from mainland China. Blood and anal cytologic samples were collected for HIV-1 serological test and HPV genotyping. A total of 889 eligible participations were included. The genotyping results of HPV were available for 822 participants (92.46%), 65.32% of which were positive for the targeted 37 HPV types. Prevalence of infection with any type of HPV was higher among HIV-infected participants (82.69%) as compared to HIV-uninfected participants (62.81%) (p < 0.01). HPV06 (15.45%), HPV18(13.50%), HPV16 (11.44%), and HPV11 (10.71%) were the most frequent types identified in the study population. Ever had paid sex with man was found to be independent predictor for HPV positivity with an adjusted odds ratios (OR) of 2.34 (1.16–4.74). Anal HPV positivity was observed to be independently associated with HIV infection with an adjusted OR of 3.03 (1.76–5.21) in the study population. In conclusion, the prevalence of anal HPV infection was observed to be common among MSM from mainland China, and it was significantly associated with the status of HIV infection.

Abstract
Supplemental Digital Content is available in the text Background: To estimate incidence and clearance of high-risk human papillomavirus (HR-HPV), and their risk factors, in men who have sex with men (MSM) recently infected by HIV in Spain; 2007–2013. Methods: Multicenter cohort. HR-HPV infection was determined and genotyped with linear array. Two-state Markov models and Poisson regression were used. Results: We analysed 1570 HR-HPV measurements of 612 MSM over 13 608 person-months (p-m) of follow-up. Median (mean) number of measurements was 2 (2.6), median time interval between measurements was 1.1 years (interquartile range: 0.89–1.4). Incidence ranged from 9.0 [95% confidence interval (CI) 6.8–11.8] per 1000 p-m for HPV59 to 15.9 (11.7–21.8) per 1000 p-m for HPV51. HPV16 and HPV18 had slightly above average incidence: 11.9/1000 p-m and 12.8/1000 p-m. HPV16 showed the lowest clearance for both ‘prevalent positive’ (15.7/1000 p-m; 95% CI 12.0–20.5) and ‘incident positive’ infections (22.1/1000 p-m; 95% CI 11.8–41.1). More sexual partners increased HR-HPV incidence, although it was not statistically significant. Age had a strong effect on clearance (P-value < 0.001) due to the elevated rate in MSM under age 25; the effect of HIV-RNA viral load was more gradual, with clearance rate decreasing at higher HIV-RNA viral load (P-value 0.008). Conclusion: No large variation in incidence by HR-HPV type was seen. The most common incident types were HPV51, HPV52, HPV31, HPV18 and HPV16. No major variation in clearance by type was observed, with the exception of HPV16 which had the highest persistence and potentially, the strongest oncogenic capacity. Those aged below 25 or with low HIV-RNA- viral load had the highest clearance.

Abstract
Background Oncogenic human papillomavirus (HPV) infection, particularly multiple HPV types, is recognized as a necessary cause of anal cancer. However, a limited number of studies have reported the prevalence of anal HPV infection in Asia. We determined the prevalence, genotypes, and risk factors for anal HPV infection in Japanese HIV-positive men who have sex with men (MSM), heterosexual men, and women. Methods This cross-sectional study included 421 HIV-positive patients. At enrollment, we collected data on smoking, alcohol, co-morbidities, drugs, CD4 cell counts, HIV RNA levels, highly active anti-retroviral therapy (HAART) duration, sexually transmitted infections (STIs), and serological screening (syphilis, hepatitis B virus, Chlamydia trachomatis, Entamoeba histolytica). Anal swabs were collected for oncogenic HPV genotyping. Results Oncogenic HPV rate was 75.9% in MSM, 20.6% in heterosexual men, and 19.2% in women. HPV 16/18 types were detected in 34.9% of MSM, 17.7% of heterosexual men, and 11.5% of women. Multiple oncogenic HPV (≥2 oncogenic types) rate was 54.6% in MSM, 8.8% in heterosexual men, and 0% in women. In univariate analysis, younger age, male sex, MSM, CD4 <100, HIV viral load >50,000, no administration of HAART, and having ≥2 sexually transmitted infections (STIs) were significantly associated with oncogenic HPV infection, whereas higher smoking index and corticosteroid use were marginally associated with oncogenic HPV infection. In multivariate analysis, younger age (OR, 0.98 [0.96–0.99]), MSM (OR, 5.85 [2.33–14.71]), CD4 <100 (OR, 2.24 [1.00–5.01]), and having ≥2 STIs (OR, 2.81 [1.72–4.61]) were independently associated with oncogenic HPV infection. These 4 variables were also significant risk factors for multiple oncogenic HPV infection. Conclusions Among Japanese HIV-infected patients, approximately two-thirds of MSM, one-fifth of heterosexual men, and one-fifth of women have anal oncogenic HPV infection. Younger age, MSM, ≥2 STIs, and immunosuppression confer a higher risk of infection with oncogenic HPV and multiple oncogenic types.

Abstract
Human papillomaviruses (HPVs) cause cancer at multiple anatomic sites in men and women, including cervical, oropharyngeal, anal, vulvar and vaginal cancers in women and oropharyngeal, anal and penile cancers in men. In this EUROGIN 2014 roadmap, differences in HPV-related cancer and infection burden by gender and anatomic site are reviewed. The proportion of cancers attributable to HPV varies by anatomic site, with nearly 100% of cervical, 88% of anal and <50% of lower genital tract and oropharyngeal cancers attributable to HPV, depending on world region and prevalence of tobacco use. Often, mirroring cancer incidence rates, HPV prevalence and infection natural history varies by gender and anatomic site of infection. Oral HPV infection is rare and significantly differs by gender; yet, HPV-related cancer incidence at this site is several-fold higher than at either the anal canal or the penile epithelium. HPV seroprevalence is significantly higher among women compared to men, likely explaining the differences in age-specific HPV prevalence and incidence patterns observed by gender. Correspondingly, among heterosexual partners, HPV transmission appears higher from women to men. More research is needed to characterize HPV natural history at each anatomic site where HPV causes cancer in men and women, information that is critical to inform the basic science of HPV natural history and the development of future infection and cancer prevention efforts.

Abstract
Currently, screening for anal high-grade squamous intraepithelial lesions (anal HSIL) relies on anal cytology and high-resolution anoscopy. Since this approach has limited sensitivity and specificity for detecting anal HSIL, there is increasing interest in the role of biomarkers for predicting anal HSIL. The aim of this study is to evaluate the diagnostic accuracy of HPV E6/E7-mRNA expression for the detection of anal HSIL in MSM infected with HIV, in comparison to DNA-HR-HPV and anal cytology. This cross-sectional screening study included 101 MSM followed at the HIV-unit of La Paz University Hospital. Intra-anal swabs from patients participating in a screening program including cytology, high-resolution anoscopy and histology were analyzed. HR-HPV-DNA detection was performed by means of the CLART® HPV2 assay (GENOMICA S.A.U., Madrid, Spain). E6/E7-mRNA detection of HR-HPV-types 16, 18, 31, 33, and 45 was performed using the NucliSENS-EasyQ assay (BioMérieux, Marcy ĺEtoile, France). HR-HPV DNA and HPVE6/E7 mRNA were detected in 82% and 57% of the anal smears respectively. Anal cytology screening was abnormal in 70.3%. For the detection of HSIL sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were 71.7%, 55.6%, 57.9%, and 69.8% for E6/E7-mRNA testing, respectively, compared to 100%, 31.5%, 55.4%, and 100% for HR-HPV-DNA testing and to 83%, 40.7%, 54.9%, 73.3% of cytology testing. In comparison with the other tests, HPVE6/E7 mRNA testing yielded a lower clinical sensitivity but a higher clinical specificity and PPV for the detection of anal HSIL in MSM infected with HIV.

Abstract
BACKGROUND Research suggests that cumulative measurement of HIV exposure is associated with mortality, AIDS, and AIDS-defining malignancies. However, the relationship between cumulative HIV and non-AIDS-defining malignancies (NADMs) remains unclear. The aim of this study was to evaluate the effect of different HIV measures on NADM hazard among HIV-infected male veterans. METHODS We performed a retrospective cohort study using Veterans Affairs HIV Clinical Case Registry data from 1985 to 2010. We analyzed the relationship between HIV exposure (recent HIV RNA, % undetectable HIV RNA, and HIV copy-years viremia) and NADM. To evaluate the effect of HIV, we calculated hazard ratios for 3 common virally associated NADM [ie, hepatocarcinoma (HCC), Hodgkin lymphoma (HL), and squamous cell carcinoma of the anus (SCCA)] in multivariable Cox regression models. RESULTS Among 31,576 HIV-infected male veterans, 383 HCC, 211 HL, and 373 SCCA cases were identified. In multivariable regression models, cross-sectional HIV measurement was not associated with NADM. However, compared with <20% undetectable HIV, individuals with ≥80% had decreased HL [adjusted hazard ratio (aHR) = 0.62; 95% confidence interval (CI): 0.37 to 1.02] and SCCA (aHR = 0.64; 95% CI: 0.44 to 0.93). Conversely, each log10 increase in HIV copy-years was associated with elevated HL (aHR = 1.22; 95% CI: 1.06 to 1.40) and SCCA (aHR = 1.36; 95% CI: 1.21 to 1.52). Model fit was best with HIV copy-years. Cumulative HIV was not associated with HCC. CONCLUSIONS Cumulative HIV was associated with certain virally associated NADM (ie, HL and SCCA), independent of measured covariates. Findings underline the importance of early treatment initiation and durable medication adherence to reduce cumulative HIV burden. Future research should prioritize how to best apply cumulative HIV measures in screening for these cancers.

Abstract
Neoplasia is the second most common cause of mortality in HIV patients. The prevalence of anal cancer among men who have sex with men (MSM) has continued to increase since the introduction of antiretroviral therapy. We screened 94 HIV-infected MSM patients. We found high-grade squamous intraepithelial lesions (HSIL) in six of the patients. The calculated prevalence of HSIL was 6.4% (95% confidence interval: 2.9-13.2). The study and implementation of screening programs for high-risk groups is a priority.

Multiple human papillomavirus infections are highly prevalent in the anal canal of human immunodeficiency virus-positive men who have sex with men. BMC Infect Dis 2014; 14:671. [PMID: 25510243 PMCID: PMC4272559 DOI: 10.1186/s12879-014-0671-4] [Citation(s) in RCA: 36] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2013] [Accepted: 12/01/2014] [Indexed: 12/28/2022] Open
Abstract
Background Anal cancer has become one of the most common non-AIDS-defined tumors among Human Immunodeficiency Virus-positive (HIV+) individuals, and a rise in its incidence among HIV+ Men who have Sex with Men (MSM) has been shown, despite the introduction of Highly Active Anti-Retroviral Therapy (HAART). Human Papillomavirus (HPV) infections are highly prevalent among HIV+ MSM and recent studies have shown high rates of HPV-associated anal intraepithelial neoplasia (AIN) and anal cancer among this population. Methods In the present study we determined the prevalence and nature of HPV co-infections in the anal canal of 324 HIV+ MSM attending a high specialty medical center in Mexico City, DNA extraction and amplification with generic primers for HPV was performed, followed by detection of specific types and co-infections with INNO-Lipa, and identification of variants by amplification and sequencing of the E6 and LCR region of HPV 16. Results We found a very high prevalence of HPV infections among this cohort (86%), with more than one fourth of them (28%) positive for type 16. Among HPV16-positive patients, European variants were the most prevalent, followed by Asian-American ones. Among these individuals (HPV-16+), we identified co-infections with other 21 HPV types namely; 11, 51, 52, 6, 66, 68, 74, 18, 45, 35, 26, 44, 70, 53, 54, 82, 31, 33, 56, 58, 59. Conclusions HIV+ MSM show a very high rate of HPV infections in the anal canal and those with type 16 exhibited a multiplicity of associated types. This study emphasizes the need for an early detection of HPV infections among HIV+ MSM in order to establish its utility to prevent anal neoplasia and cancer.

Abstract
OBJECTIVE To describe the prevalence of specific HPV types among HIV-positive men who have sex with men (MSM), particularly the presence of HPV-16 and/or -18, and to determine the factors associated with anal HPV-16/18 infections. METHODS This is a cross-sectional study from a baseline cohort of 525 HIV-positive MSM, who attended an HIV Clinic in Mexico City. Socio-demographic characteristics, sexual behaviors and HIV-related parameters were assessed. Anal samples were tested for HPV DNA using the Linear Array HPV genotyping assay. RESULTS The overall prevalence of any HPV type in the anal canal among 446 participants was 93.1%. At least one oncogenic HPV type was detected in 72.2% of the subjects and HPV-16 and/or18 were detected in 30.7%. Additionally, 76.9% of patients were infected with multiple HPV types. Having more than 10 receptive sexual partners in the last 6months (OR=2.30; 95% CI 1.12-4.74) and a CD4 cell count ≤350cells/μL (OR=1.97; 95% CI 1.26-3.09) were factors positively associated with HPV-16/18 infection in the anal canal. CONCLUSION Co-infection with HPV-16/18 and other oncogenic types are predominant in this group of HIV-positive MSM. The recognition of infection with specific oncogenic types will be of aid in designing future preventive strategies that target this high-risk population.

Abstract
OBJECTIVE HIV-positive MSM are at increased risk of anal human papillomavirus (HPV) infection compared with men in the general population, and little is known about the natural history of anal HPV infection in this population. The objective of this study was to determine the incidence of and risk factors for anal type-specific HPV infection. DESIGN Prospective cohort study. METHODS HIV-positive MSM were evaluated for anal HPV DNA, lifestyle factors, and sexual risk behaviors every 6 months for at least 2 years. RESULTS The overall incidence rate of detectable type-specific anal HPV infection was 21.3 per 100 person-years [95% confidence interval (CI) 17.7-25.4] and was 13.3/100 person-years (10.5-16.6) for oncogenic HPV types. The most common incident infections were HPV 18 (3.7/100 person-years) and HPV 16 (3.5/100 person-years). An increased number of recent partners with whom the participant was the receptive partner [odds ratio (OR) 2.9 (1.6-5.1) 8+ partners vs. 0-1], an increased number of new partners in which the participant was the receptive partner [OR 1.03 (1.01-1.1) per partner], an increased number of new oral-anal contact partners in which the participant was the receptive partner [OR 1.1 (1.03-1.1) per partner], and the frequency of receptive anal intercourse [OR 1.1 (1.03-1.1) per act] all significantly increased the odds of incident HPV infection (P ≤ 0.05). CONCLUSION HIV-positive MSM have a high incidence of oncogenic anal HPV infection. Recent receptive anal sexual behaviors, including receptive anal intercourse and receptive oral-anal contact, are the most important risk factors for incident anal HPV infection.

Abstract
Background An increasing incidence of anal cancer among men, especially men who have sex with men (MSM) suggests a need to better understand anal human papillomavirus (HPV) infection among this group. Methods A cross-sectional study was conducted among MSM in Shenzhen, China. Blood was collected for HIV serological testing and syphilis serological screening, and anal swabs were collected for HPV genotyping. Difference of HPV prevalence between HIV seropositive and HIV seronegative MSM was assessed by chi-square test. Factors associated with anal canal HPV infection were assessed by univariate and multivariate logistic regression. Results A total of 408 MSM were recruited. HIV and HPV prevalence were 6.9% and 36.4%, respectively. HPV was detected in the anal canal in 71.4% of the HIV-positive MSM and in 33.8% of the HIV-negative MSM (P<0.001). Oncogenic types were seen more often in anal specimens of HIV-positive MSM than in specimens of HIV-negative MSM (P = 0.001). The HPV genotypes detected most frequently were HPV06 (8.2%), HPV16 (7.2%), HPV11 (6.4%), HPV18 (4.7%), HPV58 (4.7%), and HPV52 (4.2%). Conclusions In this study, HIV positive MSM had a higher burden of HPV infection, especially oncogenic HPV infection. HPV types 52 and 58 were as popular as those types designed for the currently available vaccine (HPV6, 11, 16, 18).

Abstract
The incidence of anal cancer is increasing in the general population and especially in high-risk groups. A total of 90% of anal cancers are caused by human papilloma virus (HPV) infection of the anal canal. Similar to cervical cancer, anal cancer progresses through a predictable series of premalignant stages before resulting in invasive cancer; this process begins with persistent HPV infection. The HPV vaccine represents a promising strategy to combat the increasing incidence of anal cancer. Human Immunodeficiency Virus (HIV) predisposes people to persistent HPV infection, dysplasia, and subsequent anal cancer. Patients infected with HIV should be targeted for vaccination against HPV. There are difficulties in targeting this population, the most notable being that the optimal age for vaccination is prior to identification with any high-risk groups. Universal vaccination against HPV represents the best strategy to achieve maximum protection against anal cancer in high-risk groups.

Abstract
Anal squamous cell carcinoma is rare in the general population but certain populations, such as persons with HIV, are at increased risk. High-risk populations can be screened for anal cancer using strategies similar to those used for cervical cancer. However, little is known about the use of such screening practices across jurisdictions. Data were collected using an online survey. Health care professionals currently providing anal cancer screening services were invited to complete the survey via email and/or fax. Information was collected on populations screened, services and treatments offered, and personnel. Over 300 invitations were sent; 82 providers from 80 clinics around the world completed the survey. Fourteen clinics have each examined more than 1000 patients. Over a third of clinics do not restrict access to screening; in the rest, eligibility is most commonly based on HIV status and abnormal anal cytology results. Fifty-three percent of clinics require abnormal anal cytology prior to performing high-resolution anoscopy (HRA) in asymptomatic patients. Almost all clinics offer both anal cytology and HRA. Internal high-grade anal intraepithelial neoplasia (AIN) is most often treated with infrared coagulation (61%), whereas external high-grade AIN is most commonly treated with imiquimod (49%). Most procedures are performed by physicians, followed by nurse practitioners. Our study is the first description of global anal cancer screening practices. Our findings may be used to inform practice and health policy in jurisdictions considering anal cancer screening.

Abstract
Individual and sexual partner characteristics may increase the risk of abnormal cervical cytology among women in human immunodeficiency virus (HIV)-discordant relationships. Papanicolaou smears were obtained in a prospective cohort of Kenyan HIV-discordant couples. Of 441 women, 283 (64%) were HIV-infected and 158 (36%) were HIV-uninfected with HIV-infected partners. Overall, 79 (18%) had low-grade and 25 (6%) high-grade cervical abnormalities. Male herpes simplex virus type 2 (HSV-2) seropositivity and lower couple socioeconomic status were associated with cervical abnormalities (p < 0.05). HIV-uninfected women with HIV-infected male sex partners (CD4 > 350 cells/µL) had the lowest prevalence of high-grade cervical lesions. HIV-infected women (CD4 > 350 cells/µL) and HIV-uninfected women with HIV-infected partners (CD4 ≤ 350 cells/µL) were at similar intermediate risk (p > 0.05), and HIV-infected women (CD4 ≤ 350 cells/µL) had significantly higher risk of high-grade cervical abnormalities (p = 0.05). Women in HIV-discordant relationships have high rates of cervical lesions and this may be influenced by couple-level factors, including HIV status and CD4 count of the infected partner.

Abstract
BACKGROUND HIV-positive men who have sex with men (MSM) have a higher prevalence of anal human papillomavirus (HPV) infection and anal cancer incidence than HIV-negative MSM. High-risk HPV persistence is an important risk factor for the development of anal cancer. METHODS A total of 123 HIV-positive and 123 HIV-negative MSM were enrolled from the Thai Red Cross AIDS Research Centre in Bangkok, Thailand, and followed for 12 months. Anal sample collection for HPV genotyping was performed at every visit. HPV prevalence, incidence, clearance, and persistence were calculated. A logistic regression model was used to study factors associated with high-risk HPV persistence. RESULTS The prevalence of any anal HPV infection was 85% in HIV-positive and 58.5% in HIV-negative MSM (P < 0.0001). The prevalence of high-risk HPV infection was 57.5% in HIV-positive and 36.6% in HIV-negative MSM (P = 0.001). HPV 16 was the most common high-risk HPV type. HIV-positive MSM had a higher prevalence (22.5% vs. 9.8%, P = 0.008) and persistence (16.7% vs. 1.3%, P < 0.001) of HPV 16 than HIV-negative MSM and a trend for higher incidence (16.1 vs. 6.1 episodes/1000 person-months, incidence rate ratio 2.6, P = 0.058). HIV infection (odds ratio: 4.45, 95% confidence interval: 2.11 to 9.4, P < 0.001) and smoking in HIV-positive MSM (odds ratio: 2.3, 95% confidence interval: 1.17 to 4.5, P = 0.015) were independently associated with high-risk HPV persistence in multivariate models. CONCLUSIONS In addition to targeting HIV-positive MSM who are at higher risk for anal, high-risk HPV persistence, anal cancer prevention programs should also integrate behavioral interventions such as smoking cessation to modify risk for high-risk HPV persistence.

Abstract
BACKGROUND There are few published estimates of anal human papillomavirus (HPV) infection rates among young men who have sex with men (YMSM). METHODS We estimated incidence and prevalence of type-specific anal HPV infection using clinician-collected anal swabs for HPV DNA testing obtained during a 1-year prospective study of 94 YMSM (mean age, 21 years) in Seattle. RESULTS Seventy percent of YMSM had any HPV infection detected during the study, and HPV-16 and/or -18 were detected in 37%. The incidence rate for any new HPV infection was 38.5 per 1000 person-months and 15.3 per 1000 person-months for HPV-16/18; 19% had persistent HPV-16/18 infection. No participant tested positive for all 4 HPV types in the quadrivalent vaccine. The number of lifetime male receptive anal sex partners was significantly associated with HPV infection. The prevalence of HPV-16/18 was 6% among YMSM with a history of 1 receptive anal sex partner and 31% among YMSM with ≥ 2 partners. CONCLUSIONS Although the high prevalence of HPV among YMSM highlights the desirability of vaccinating all boys as a strategy to avert the morbidity of HPV infection, most YMSM appear to remain naive to either HPV-16 or -18 well into their sexual lives and would benefit from HPV immunization.
