LGBTQ+ Youth Health: An Unmet Need in Pediatrics. CHILDREN 2022; 9:children9071027. [PMID: 35884011 PMCID: PMC9325167 DOI: 10.3390/children9071027] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 05/23/2022] [Revised: 07/01/2022] [Accepted: 07/05/2022] [Indexed: 11/19/2022]
Abstract
At present, lesbian, gay, bisexual, transgender, queer and intersex people (LGBTQ+) are increasingly being empowered to freely express themselves, particularly young people and rising generations. Although data underline the trend of more open expression of different sexual orientations and gender identities, LGBTQ+ adolescents still suffer discrimination in the health care framework. Inclusive care by providers to look after the health of LGBTQ+ indiviuals is needed. Pediatricians are often the first health care providers for LGBTQ+ youth facing their sexual and gender identities. Unfortunately, pediatricians have limited knowledge about LGBTQ+ issues, which keeps them from fulfilling the specific needs of LGBTQ+ youth. The purpose of this review is to frame the most important aspects of LGBTQ+ youths’ lives, including risks, difficulties and needs, that pediatricians should investigate and meet to provide these youth with better and more individualizedassistance regarding their health. A literature analysis showed that pediatricians have insufficient knowledge of and comfort with several items regarding the management of LGBTQ+ youths. Increased awareness and knowledge of the specific and exclusive needs of LGBTQ+ adolescents are mandatory, including dedicated pediatric LGBTQ+ health care training. This would give them the opportunity to forward an inclusive health care system, thus reducing the risks related to stigma, bullying and family rejection and promoting sex education. Further studies are needed to better evaluate the prevalence of LGBTQ+ youths, gender-based medicine in pediatrics and the effects of COVID-19 on the LGBTQ+ younth population due to increased risks of psychosocial suffering, isolation and mental diseases.

Identifying risk factors for prevalent anal human papillomavirus type 16 infection in women living with HIV. PLoS One 2022; 17:e0268521.

Abstract
Background Women living with HIV (WLHIV) have a high risk of anal cancer. Identifying risk factors for anal HPV 16 infection, the most significant risk factor for anal cancer, is essential for prevention and screening strategies. Methods In the EVVA Cohort study, 151 WLHIV had cervical and anal HPV testing with genotyping every 6 months for 2 years, while demographic and clinical data were collected via questionnaires and chart reviews. Here, we present results of baseline data analyzed using multivariable logistic regression. Results Among 150 women with adequate HPV test results at baseline, HPV 16 DNA was detected anally in 23 (15.3%; 95%CI:10.4–22.1) and cervically in 5 (3.3%; 95%CI:1.4–7.8). In multivariable analysis, current smoking (OR = 6.0; 95%CI: 1.5–23.9), nadir CD4 count ≤ 200 cells/μL (OR = 8.4; 95%CI: 2.0–34.3), prevalent cervical HPV 16 (OR = 14.7; 95%CI: 1.0–222.5) and anogenital herpes in previous 6 months (OR = 9.8, 95%CI: 1.7–56.8) were associated with prevalent anal HPV 16. Conclusions Knowledge of risk factors can help identify WLHIV at greatest risk of anal HPV 16 infection and, potentially, developing subsequent anal cancer. Identification of the subgroup of these women in whom HPV 16 persists could be an early step in the algorithm of anal cancer screening.

Screening Women for Anal Cancers: Guidance for Health Care Professionals. Am J Gastroenterol 2021; 116:509-516. [PMID: 33606380 DOI: 10.14309/ajg.0000000000001186] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/11/2020] [Accepted: 01/11/2021] [Indexed: 12/11/2022]
Abstract
Anal cancer is rare in the general population but is steadily increasing in incidence over the past decade especially in women. Identification and screening of women with high risk facilitates detection of anal precancer and early-stage cancer, improves survival, and potentially uses less invasive therapies compared with the conventional chemoradiation treatments used for advanced cancers. No recently published guidelines currently describe details about screening women for anal squamous cell cancer (ASCC). The available evidence supports the existence of groups of women with higher prevalence of ASCC (e.g., women with human immunodeficiency virus, immune suppression, or previous lower-genital high-grade lesion or cancer) who would likely benefit from screening with some combination of anal cytology and human papillomavirus testing. Additional research is needed to establish the cost-effectiveness and the influence of screening on ASCC mortality rates.

Abstract
BACKGROUND Cervical cancer screening might contribute to the prevention of anal cancer in women. We aimed to investigate if routine cervical cancer screening results-namely high-risk human papillomavirus (HPV) infection and cytohistopathology-predict anal HPV16 infection, anal high-grade squamous intraepithelial lesions (HSIL) and, hence, anal cancer. METHODS We did a systematic review of MEDLINE, Embase, and the Cochrane library for studies of cervical determinants of anal HPV and HSIL published up to Aug 31, 2018. We centrally reanalysed individual-level data from 13 427 women with paired cervical and anal samples from 36 studies. We compared anal high-risk HPV prevalence by HIV status, cervical high-risk HPV, cervical cytohistopathology, age, and their combinations, using prevalence ratios (PR) and 95% CIs. Among 3255 women with anal cytohistopathology results, PRs were similarly calculated for all anal HSIL and HPV16-positive anal HSIL. FINDINGS Cervical and anal HPV infections were highly correlated. In HIV-negative women, anal HPV16 prevalence was 41% (447/1097) in cervical HPV16-positive versus 2% (214/8663) in cervical HPV16-negative women (PR 16·5, 95% CI 14·2-19·2, p<0·0001); these values were 46% (125/273) versus 11% (272/2588) in HIV-positive women (4·4, 3·7-5·3, p<0·0001). Anal HPV16 was also associated with cervical cytohistopathology, with a prevalence of 44% [101/228] for cervical cancer in HIV-negative women (PR vs normal cytology 14·1, 11·1-17·9, p<0·0001). Anal HSIL was associated with cervical high-risk HPV, both in HIV-negative women (from 2% [11/527] in cervical high-risk HPV-negative women up to 24% [33/138] in cervical HPV16-positive women; PR 12·9, 95% CI 6·7-24·8, p<0·0001) and HIV-positive women (from 8% [84/1094] to 17% [31/186]; 2·3, 1·6-3·4, p<0·0001). Anal HSIL was also associated with cervical cytohistopathology, both in HIV-negative women (from 1% [5/498] in normal cytology up to 22% [59/273] in cervical HSIL; PR 23·1, 9·4-57·0, p<0·0001) and HIV-positive women (from 7% [105/1421] to 25% [25/101]; 3·6, 2·5-5·3, p<0·0001). Prevalence of HPV16-positive anal HSIL was 23-25% in cervical HPV16-positive women older than 45 years (5/20 in HIV-negative women, 12/52 in HIV-positive women). INTERPRETATION HPV-based cervical cancer screening programmes might help to stratify anal cancer risk, irrespective of HIV status. For targeted secondary anal cancer prevention in high-risk groups, HIV-negative women with cervical HPV16, especially those older than 45 years, have a similar anal cancer risk profile to that of HIV-positive women.

Abstract
BACKGROUND Defective cell-mediated immunity increases the risk of human papillomavirus-associated anal dysplasia and cancer. There is limited information on anal canal disease in patients with IBD. OBJECTIVE The purpose of this study was to assess anal/vaginal human papillomavirus and anal dysplasia prevalence in patients with IBD. DESIGN Patients had an anal examination before routine colonoscopy. SETTINGS The study was conducted at a tertiary IBD referral center. PATIENTS We studied a convenience sample of sexually active male and female patients with IBD who were not on biological therapy. INTERVENTION Anal examination, anal and vaginal human papillomavirus testing, anal cytology, and high-resolution anoscopy/biopsy were carried out. MAIN OUTCOME MEASURES Anal and vaginal human papillomavirus types, anal cytology, and biopsy grade were measured. RESULTS Twenty-five male and 21 female evaluable participants, 31 with Crohn's disease, 14 with ulcerative colitis, and 1 with indeterminate colitis, were predominantly white (91.3%), treatment experienced (76.1%), an average age of 38.1 years (range, 22.0-66.0 y), and had an average length of IBD diagnosis of 9.3 years (range, 1.0-33.0 y). Eighteen (39.1%) had an abnormal perianal examination and 3 (6.5%) had an abnormal digital examination. Forty-one (89.1%) had anal human papillomavirus, 16 with a single type and 25 with multiple types (range, 2-5 types). Human papillomavirus type 16 was most common (65.2%), followed by human papillomavirus types 11 and 45 (37.0% each). Nineteen of 21 (90.5%) women had vaginal human papillomavirus. Overall, 21 (45.7%) had abnormal anal cytology. Thirty three (71.7%) had ≥1 anal biopsy (9 had multiple), with dysplasia diagnosed in 28 (60.9%) and high-grade and low-grade squamous intraepithelial lesions diagnosed in 4 (8.7%) and 24 (43.5%). LIMITATIONS No control group was included, and no detailed sexual history was taken. CONCLUSIONS A high prevalence of anal and vaginal human papillomavirus and anal dysplasia was demonstrated in the study population outcomes. See Video Abstract at http://links.lww.com/DCR/A379.

Abstract
Lesbian, gay, bisexual, transgender (LGBT), and questioning youth represent a diverse population who are affected by many sexual health inequities, including increased risk for human immunodeficiency virus (HIV) and sexually transmitted infections (STIs). To provide comprehensive sexual health care for LGBT youth, providers should set the stage with a nonjudgmental, respectful tone. Providers should be competent in recognizing symptoms of STIs and HIV and aware of the most up-to-date screening guidelines for LGBT youth. Sexual health visits should also focus on prevention, including safer sex practices, HIV pre-exposure and post-exposure prophylaxis, family planning, and immunization for hepatitis and human papillomavirus.

Prevalence of anal human papillomavirus infection and anal HPV-related disorders in women: a systematic review. Am J Obstet Gynecol 2015; 213:278-309.

Abstract
The aim of this study was to systematically review the findings of publications addressing the epidemiology of anal human papillomavirus (HPV) infection, anal intraepithelial neoplasia, and anal cancer in women. We conducted a systematic review among publications published from Jan. 1, 1997, to Sept. 30, 2013, to limit to publications from the combined antiretroviral therapy era. Three searches were performed of the National Library of Medicine PubMed database using the following search terms: women and anal HPV, women anal intraepithelial neoplasia, and women and anal cancer. Publications were included in the review if they addressed any of the following outcomes: (1) prevalence, incidence, or clearance of anal HPV infection, (2) prevalence of anal cytological or histological neoplastic abnormalities, or (3) incidence or risk of anal cancer. Thirty-seven publications addressing anal HPV infection and anal cytology remained after applying selection criteria, and 23 anal cancer publications met the selection criteria. Among HIV-positive women, the prevalence of high-risk (HR)-HPV in the anus was 16-85%. Among HIV-negative women, the prevalence of anal HR-HPV infection ranged from 4% to 86%. The prevalence of anal HR-HPV in HIV-negative women with HPV-related pathology of the vulva, vagina, and cervix compared with women with no known HPV-related pathology, varied from 23% to 86% and from 5% to 22%, respectively. Histological anal high-grade squamous intraepithelial lesions (anal intraepithelial neoplasia 2 or greater) was found in 3-26% of the women living with HIV, 0-9% among women with lower genital tract pathology, and 0-3% for women who are HIV negative without known lower genital tract pathology. The incidence of anal cancer among HIV-infected women ranged from 3.9 to 30 per 100,000. Among women with a history of cervical cancer or cervical intraepithelial neoplasia 3, the incidence rates of anal cancer ranged from 0.8 to 63.8 per 100,000 person-years, and in the general population, the incidence rates ranged from 0.55 to 2.4 per 100,000 person-years. This review provides evidence that anal HPV infection and dysplasia are common in women, especially in those who are HIV positive or have a history of HPV-related lower genital tract pathology. The incidence of anal cancer continues to grow in all women, especially those living with HIV, despite the widespread use of combined antiretroviral therapy.

Abstract
OBJECTIVE The incidence of anal cancer is higher in women than men in the general population and has been increasing for several decades. Similar to cervical cancer, most anal cancers are associated with human papillomavirus (HPV), and it is believed that anal cancers are preceded by anal high-grade squamous intraepithelial lesions (HSIL). Our goals were to summarize the literature on anal cancer, HSIL, and HPV infection in women and to provide screening recommendations in women. METHODS A group of experts convened by the American Society for Colposcopy and Cervical Pathology and the International Anal Neoplasia Society reviewed the literature on anal HPV infection, anal SIL, and anal cancer in women. RESULTS Anal HPV infection is common in women but is relatively transient in most. The risk of anal HSIL and cancer varies considerably by risk group, with human immunodeficiency virus-infected women and those with a history of lower genital tract neoplasia at highest risk compared with the general population. CONCLUSIONS While there are no data yet to demonstrate that identification and treatment of anal HSIL leads to reduced risk of anal cancer, women in groups at the highest risk should be queried for anal cancer symptoms and required to have digital anorectal examinations to detect anal cancers. Human immunodeficiency virus-infected women and women with lower genital tract neoplasia may be considered for screening with anal cytology with triage to treatment if HSIL is diagnosed. Healthy women with no known risk factors or anal cancer symptoms do not need to be routinely screened for anal cancer or anal HSIL.

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
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 Little is known about the incidence of anal human papillomavirus (HPV) infection and related sequelae, as well as factors associated with these outcomes, among adolescents who are HIV infected versus HIV uninfected but at risk. METHODS We analyzed the data from a multisite US study, the Reaching for Excellence in Adolescent Care and Health Project. Adolescents aged 12 to 18 years who were behaviorally HIV infected (n = 319) or HIV uninfected but at risk (n = 177) were recruited. Incidence rates for anal HPV, high-risk anal HPV, anogenital warts, and anal dysplasia were calculated using Poisson modeling. Factors associated with these outcomes were examined using Cox proportional hazards modeling. RESULTS Mean age at entry was 16.8 years; mean (SD) follow-up time for detection of anal HPV was 22.4 (10.8) months. Most participants (76%) were female; 70% were black non-Hispanic. HIV-infected (vs. HIV-uninfected) women had a significantly higher incidence of anal HPV (30 vs. 14 per 100 person-years; P = 0.002), high-risk anal HPV (12 vs. 5.3 per 100 person-years; P = 0.04), and anogenital warts (6.7 vs. 1.6 per 100 person-years; P = 0.002) but not anal dysplasia. Although incidence rates were higher for these outcomes among HIV-infected versus HIV-uninfected men, the differences were not statistically significant. Among women, factors associated with anal HPV and related sequelae differed by HIV status and included biological, behavioral, and HIV-related factors. No factors were associated with outcomes in men. CONCLUSIONS HIV-infected versus HIV-uninfected adolescent women had higher rates of anal HPV and anogenital warts. Because HIV-infected youth are at increased risk of these outcomes, enhanced HPV prevention efforts such as vaccination are warranted for this group.

Abstract
OBJECTIVES We examined the role of adolescent peer violence victimization (PVV) in sexual orientation disparities in cancer-related tobacco, alcohol, and sexual risk behaviors. METHODS We pooled data from the 2005 and 2007 Youth Risk Behavior Surveys. We classified youths with any same-sex sexual attraction, partners, or identity as sexual minority and the remainder as heterosexual. We had 4 indicators of tobacco and alcohol use and 4 of sexual risk and 2 PVV factors: victimization at school and carrying weapons. We stratified associations by gender and race/ethnicity. RESULTS PVV was related to disparities in cancer-related risk behaviors of substance use and sexual risk, with odds ratios (ORs) of 1.3 (95% confidence interval [CI] = 1.03, 1.6) to 11.3 (95% CI = 6.2, 20.8), and to being a sexual minority, with ORs of 1.4 (95% CI = 1.1, 1.9) to 5.6 (95% CI = 3.5, 8.9). PVV mediated sexual orientation disparities in substance use and sexual risk behaviors. Findings were pronounced for adolescent girls and Asian/Pacific Islanders. CONCLUSIONS Interventions are needed to reduce PVV in schools as a way to reduce sexual orientation disparities in cancer risk across the life span.

Abstract
BACKGROUND Anal cancer is more common in women than in men, yet little is known about the natural history of human papillomavirus (HPV) in women. The objective was to examine the natural history of anal HPV in heterosexual women. METHODS Young women participating in an HPV cohort study were seen at 4-month intervals for cervical and anal HPV testing. Time to clearance was estimated using the Kaplan-Meier approach; risks for persistence were assessed using Cox regression models. RESULTS Seventy-five women (mean age, 23.5 ± 4.1 years) who tested positive for anal HPV were followed for a mean of 84.5 ± 44.9 months. By 3 years, 82.5% of anal non-16 high-risk (HR) HPV, 82.6% of low-risk (LR) HPV, and 76.2% of HPV-16 infections had cleared. By 3 years, only 36.4% of women had become negative for all HPV types. In the multivariable model, concurrent cervical HPV-16 (P < .001), weekly alcohol use (P = .015), anal touching during sex (P = .045), recent anal sex (P = .04), and no condom use during anal sex (P = .04) were associated with HPV-16 persistence. Greater number of new sex partners (P = .024) and condom use during vaginal sex (P = .003) were associated with clearance. Similar associations were found for clearance in all HR-HPV infections. Only concomitant cervical HPV was associated with non-16 HR-HPV persistence. CONCLUSIONS The majority of anal HPV infections cleared within 3 years. HPV-16 infections were slower to clear than other HR-HPV infections, consistent with its role in anal cancer. Specific sexual behaviors were associated with persistence, suggesting that education and behavioral interventions may decrease persistence.

Abstract
Adolescents make up an increasing percentage of the U.S. population with human immunodeficiency virus (HIV). Adolescent-focused care is critical to identify and reduce at-risk behavior, comorbidities, and partner transmission. Optimal medical and reproductive health care, both now and in the future, with an adolescent-focused approach, are important for HIV-infected adolescents. Adolescents who are infected with HIV should receive care that allows them to realize their sexual and reproductive goals while maximizing their personal health and minimizing the risk of unintended pregnancy, acquisition of new sexually transmitted infections, and transmission of infection to partners or offspring. Key strategies for preventing the spread of infection include, early diagnosis, guideline-based treatment, and partner notification of HIV status.

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.

Abstract
BACKGROUND Human immunodeficiency virus (HIV)-infected individuals are at greater risk for human papillomavirus (HPV)-associated anal than oropharyngeal cancers. The prevalence of anal vs oral HPV infections is higher in this population, but whether this is explained by higher incidence or persistence is unknown. METHODS Oral rinse and anal swab samples were collected semiannually from 404 HIV-infected adults in Baltimore, Maryland. Samples were tested for 37 HPV types using PGMY09/11 primers and reverse line-blot hybridization. Risk factors for HPV persistence were explored using adjusted Wei-Lin-Weissfeld models. RESULTS The prevalence (84% vs 28%), incidence (145 vs 31 per 1000 person-months), and 12-month persistence (54% vs 29%) were higher for anal vs oral HPV infections, respectively (each P < .001). Heterosexual men had lower incidence of anal HPV than men who have sex with men and women, but a higher incidence of oral HPV infection (test of interaction P < 0.001). In adjusted analyses, risk factors for HPV persistence included prevalent vs incident (adjusted hazard ratio [aHR] = 4.0; 95% confidence interval [CI], 3.5-4.8) and anal vs oral HPV infections (aHR = 1.5; 95% CI, 1.2-1.9). CONCLUSIONS The higher incidence and persistence of anal vs oral HPV infections likely contributes to the higher burden of anal as compared to oral HPV-associated cancers in HIV-infected individuals.

Abstract
Studies conducted in HIV-seropositive individuals have enhanced our understanding of the natural history of anal intraepithelial neoplasia (AIN) and of factors predictive of progression to high-grade AIN, the immediate precursor to anal cancer. AIN is frequently detected in HIV-seropositive individuals. Factors that increase the risk for AIN include HIV infection, low current or nadir blood CD4+ cell counts, receptive anal intercourse, oncogenic human papillomavirus (HPV) infection, persistent anal HPV infection, multiple HPV type infections and high anal HPV viral load. This review confirms the importance of high-grade AIN in HIV-seropositive individuals and HIV-seronegative men having sex with men.

Abstract
A cross-sectional study was conducted to investigate the prevalence, types, and risk factors associated with anal HPV infection among HIV-infected men in outpatient clinics at an AIDS designated hospital in Taiwan. Anal swabs were collect and PCR (polymerase chain reaction) was used to analyze the types of anal HPV infection. HPV DNA was detected in 74.2% of the 198 participants, including high-risk types (40.4%), low-risk types (18.2%) and multiple-types (6%). The most common types were HPV 16 (13.1%), 6 (10.4%), 11 (7.1%) and 18 (6.1%). The significant risk factor for being infected with any type or a high-risk type of HPV was having sexual partners (>3) in the preceding 6 months. Low-risk type of anal HPV infection was associated with a history of anal lesions. Our findings support the need for regular follow-up of all HIV/HPV coinfected patients and their partners to allow early detection of anal intraepithelial neoplasia.

Abstract
Disparities in cancer burden between specific populations are widely acknowledged, including differences associated with sexual orientation. We searched PubMed for articles about cancer in men who have sex with men. Of the 410 publications that we identified, 47 reports were eligible for inclusion and review. Most addressed issues of cancer prevention, followed by diagnosis, survivorship, detection, and cancer treatment. Disparities exist mainly in the prevalence of viruses linked to cancers. Knowledge about sexual orientation and cancer is skewed towards infection-related cancers, so information about the association between sexual orientation and other cancers, and social and cultural causes for disparities in cancer, is less available. Men who have sex with men are still a largely overlooked minority group in this respect. Future research should examine the effects of sexual orientation on cancer, from prevention to survivorship.

Abstract
Men who have sex with men (MSM) especially those who are HIV positive are at risk for HPV-associated anal cancer. We systematically reviewed studies with data on the prevalence of vaccine preventable anal HPV among men who have sex with men aged 25 or younger and identified 6 studies. None of these studies were specifically designed to determine the prevalence of HPV in this population. Available data, albeit limited, suggest many young MSM may not already be HPV infected. Further studies using representative sampling focused on teenage MSM are required to confirm this.

Abstract
Anal cancer is a rare disease. Nevertheless, it may be a reason for concern among groups in which its incidence is increasing: those who engage in anoreceptive intercourse, promiscuous persons, and those with sexually transmitted infections (HPV and HIV). The aim of this study was to evaluate the prevalence of abnormal anal cytology in women infected with HIV seen at Hospital de Clínicas de Porto Alegre, Brazil. A cross-sectional design was used. Anal smear screening was offered to all women infected with HIV seen at the hospital's outpatient sexually transmitted infections clinic from March 2006 to March 2008. A total of 184 patients were thus enrolled. Only patients who gave written consent were included in the study. The prevalence of abnormal anal cytology was 14.1% (26 patients). Twenty-two patients presented atypical squamous cells of undetermined significance, and four exhibited low-grade intraepithelial neoplasia. Initially, abnormal anal cytology was significantly associated with age, number of pregnancies, smoking, abnormal cervical cytology, CD4⁺ < 200 cells/mm³ and hepatitis C co-infection. After adjustment, only CD4⁺ < 200 cells/mm³ and smoking were found to increase the risk of altered anal cytology. The anal Pap method described is simple and can be used for screening in cohorts of HIV-positive women who are at risk of developing anal carcinoma, mainly those with CD4⁺ counts <200 cells/mm³ and smokers.

Abstract
The goal of this review is to summarise epidemiological data that support an understanding of the natural history of anal human papillomavirus (HPV) among women and men having sex with women (MSW). HPV is a common infection of the anal canal among women and MSW. Although there have been a limited number of studies to date, both oncogenic and nononcogenic HPV genotypes commonly occur among these populations even when individuals do not report receptive anal sex. Genotype distribution is quite diverse, with recent studies typically detecting more than two dozen genotypes in the anal canal in samples of women and MSW. Factors most consistently associated with HPV in the anal canal among both women and MSW are lifetime number of sexual partners and detection of HPV at the genitals. The common finding of genotypic concordance between the genitals and anal canal in women and MSW, and the infectious nature of HPV, in addition to a limited number of studies offering empirical evidence of anal-to-genital self-inoculation and evidence of HPV hand carriage, may help explain the detection of HPV in the anal canal outside the context of receptive anal sex. HPV vaccination has been shown to reduce anal HPV infection among women and is also a promising prevention strategy among MSW.

Abstract
PURPOSE Global data on age-specific prevalence of human papillomavirus (HPV) infection in males, especially for oncogenic HPV types 16 and 18, are essential for future efforts to prevent HPV-related diseases, including expanded access to HPV prophylactic vaccines for boys and young men. METHODS A systematic review of peer-reviewed publications was conducted to summarize worldwide data on genital HPV-DNA prevalence in men. Studies using polymerase chain reaction or hybrid capture detection assays were included. RESULTS Approximately 6,600 abstracts were identified. Of them, 64 reported age-specific HPV prevalence and were included in the review. Of these, 38 were from populations at high risk of HPV infections, such as sexually transmitted infection clinic attendees, human immunodeficiency virus-positive males, and male partners of women with HPV infection or abnormal cytology. The largest proportions of studies were from Europe (38%) and North America (25%), with smaller proportions from Central and South America (19%), Asia (11%), and Africa (5%). Across all regions, data on HPV prevalence were generally limited to men >18 years of age. HPV prevalence was high among sexually active men in all regions but with considerable variation, from 1% to 84% among low-risk men and from 2% to 93% among high-risk men. Peak HPV prevalence spanned a wide range of ages and was generally not concentrated in the younger age groups. Age-specific prevalence curves were relatively flat or declined only slightly following peak prevalence. CONCLUSIONS Genital HPV infection in men varies widely, both between and within high- and low-risk groups and by geographic region. Compared with that in women, HPV prevalence in men seems to peak at slightly older ages and remains constant or decreases slightly with increasing age, suggesting persistent HPV infection or a higher rate of reinfection.

Abstract
BACKGROUND Although human papillomavirus (HPV) infections are common in young women, the rate of and risk for repeated new infections are not well documented. We examined the rate of and risks for new HPV detection in young women. METHODS We used data from an ongoing study of HPV, initiated in 1990. Sexually active women ages 12 to 22 years were eligible. Interviews on behaviors and HPV testing were done at 4-month intervals; sexually transmitted infection (STI) testing was annual or if symptomatic. Starting with first HPV detection, time to the next (second) visit (event) with detection of new HPV types, and then the second event to time to third event was calculated. Risks were determined using Cox proportional hazard model. RESULTS Sixty-nine percent of 1,125 women had a second event, and of those with a second event, 63% had a third event by 3 years, respectively. Women with HPV persistence from initial visit to second event [hazard ratio (HR) = 4.51 (3.78-5.37)], an STI [HR = 1.47 (1.00-2.17)], bacterial vaginosis [HR = 1.60 (1.07-2.39)], and number of new sex partners [HR = 1.10 (1.05-1.15 per partner/mo)] were independent associations for HPV. Risks for third event were similar. CONCLUSION This study documents the repeated nature of HPV infections in young women and their association with sexual risk behaviors. IMPACT This finding underscores the lack of clinical utility of HPV testing in young women. Further studies are needed to examine host factors that lead to HPV acquisition and persistence.

Abstract
OBJECTIVE The purpose of this study was to assess the prevalence of and risk factors for abnormal anal cytology and human papillomavirus (HPV) infections in women who are human immunodeficiency virus (HIV) positive. STUDY DESIGN We conducted an observational single center study of 100 HIV-infected women with cervical and anal specimens that were obtained for cytologic and high-risk HPV testing with Hybrid Capture 2. RESULTS Seventeen women had abnormal anal cytology; 16 women had anal HPV; 21 women had abnormal cervical cytology, and 24 women had cervical HPV. Abnormal anal cytology was associated with cervical HPV infection, abnormal cervical cytology, and anal HPV infection in univariate analysis. In multivariate analysis, abnormal anal cytology was associated with a CD4 count <200 cells/mm(3), a history of sexually transmitted disease, and concurrent cervical cytologic abnormality. CONCLUSION HIV-infected women are at high risk for abnormal cytology and HPV infections of both the anus and cervix. Risk factors for abnormal anal cytology include abnormal cervical cytology, cervical and anal HPV infections, and low CD4 count.

Abstract
BACKGROUND Although the primary cause of anal cancer is human papillomavirus (HPV) infection in the anal canal, little attention has been paid to the epidemiology of anal HPV infection in men who have sex with women (MSW). METHODS Exfoliated cells from the anal canal of 902 MSW in Brazil (São Paulo), Mexico (Cuernavaca), and the United States (Tampa) were tested for HPV DNA. RESULTS The prevalence of HPV infection in the anal canal (12.0%) was similar among MSW in each city (P=.77), whereas 7.0% had infection with oncogenic types. Men in Tampa had a 4-fold higher prevalence of infection with HPV type 16 (HPV-16) than that among men in São Paulo or Cuernavaca (P<.001). Duration of relationship with a primary sex partner and ever having oral or anal sex with a man was associated with infection with any HPV type and with any oncogenic type, whereas lifetime number of female sex partners was associated with infection with any HPV type. CONCLUSIONS Anal canal HPV infection is commonly found among MSW, and the prevalence of infection with HPV-16 may differ substantially by geography. Men who have a larger lifetime number of female sex partners, who are in a sexual relationship of <1 year in duration, and who have a history of oral or anal sex with men were most likely to have an anal HPV infection.

Abstract
Little research addresses the role of anal sexuality and anal sexual behaviors as a widely practiced but relatively less frequent element of a heterosexual sexual repertoire. However, the importance of anal sex in sexual health is increasingly well-defined by epidemiological and clinical studies. This article reviews existing data on a range of heterosexual anal sex practices and provides conceptual and methodological recommendations for new research.

Abstract
HIV-infected patients are at increased risk for persistent human papillomavirus (HPV) infection, the major cause of anogenital cancer. The present study describes the HPV prevalence in urine samples of 243 HIV-infected men and a control group of 231 men. HPV DNA was amplified by the SPF10 polymerase chain reaction primer set. The overall HPV prevalence in HIV-infected men was 27.5% compared with 12.6% in controls (P < 0.01). Infections with high-risk and multiple HPV genotypes were present in both groups. Differences were not statistically significant. A multivariate logistic regression model showed a decreased HPV prevalence associated with use of a nucleoside and a non-nucleoside reverse transcriptase inhibitor combination (P = 0.03). A trend was observed towards a higher HPV prevalence and a lower CD4 cell count. Further prospective studies are needed to determine the role of HPV DNA testing in urine in future screening programmes for anal cancer in men.

Abstract
OBJECTIVES Describe the type-specific prevalence of anal HPV infection in women with lower genital tract intraepithelial neoplasia and cancer. Describe the prevalence of abnormal anal cytology and identify risk factors for anal HPV infection and abnormal anal cytology in this population. METHODS We performed a cross-sectional study of women attending 2 university-based colposcopy clinics with high-grade lower genital tract intraepithelial neoplasia or cancer. Participants received anal HPV testing/typing, anal cytology and completed a questionnaire detailing medical history and sexual behavior. RESULTS Of the 102 women enrolled, 92 (90%) had adequate beta-globin for analysis of HPV DNA status, and 47/92 women (51%) had detectable anal HPV. Of the 15 HPV types identified, 9 (60%) were oncogenic types and 6 (40%) were non-oncogenic or undetermined risk types. Overall, 9 women (9%) had abnormal anal cytology, and 7 of those had corresponding anal intraepithelial neoplasia grade I (AIN I). Women with vulvar disease had the highest proportion of abnormal anal cytology (21%) compared to women with cervical disease alone (7%), but this difference was not statistically significant (p=0.10). Neither anal HPV infection nor abnormal cytology was significantly associated with anal sex practices, smoking or number of sexual partners. CONCLUSIONS Anal infection with high-risk HPV types is common in women with high-grade genital neoplasia, but was not associated with known risk factors for genital HPV infection. Other unidentified risk factors may play a role in the anal HPV infection in this population. Abnormal anal cytology was rare and larger studies are needed to identify risk factors associated with abnormal cytology and anal intraepithelial neoplasia in this population.

Abstract
In this article, gynecologic conditions of increased importance in the HIV-infected woman are discussed. Women living with HIV may have an increase in menstrual disorders, lower genital tract neoplasias, gynecologic surgery, and sexually transmitted infections. The literature relevant to choosing a method of contraception for HIV-positive women is also discussed. With the advent of HAART, seropositive women are now facing issues around longevity, such as menopause and disorders of bone mineral density, as well as those associated with fertility.

Abstract
BACKGROUND Anal cancer is an uncommon malignancy in the US; up to 93% of anal cancers are associated with human papillomavirus. METHODS Cases diagnosed between 1998 and 2003 from 39 population-based cancer registries were analyzed. The following anal cancer histologies were included in the analysis: squamous cell, adenocarcinoma, and small cell/neuroendocrine carcinomas. Incidence rates were age-adjusted to the 2000 US standard population. RESULTS From 1998 through 2003, the annual age-adjusted invasive anal cancer incidence rate was 1.5 per 100,000 persons. Squamous cell carcinoma (SCC) was the most common histology overall, accounting for 18,105 of 21,395 (84.6%) cases of anal cancer. Women had a higher rate of SCC (1.5 per 100,000) than men (1.0). Whites and blacks had the highest incidence rate (1.3), whereas Asians/Pacific Islanders (API) had the lowest rate (0.3). Incidence rates of anal SCC increased 2.6% per year on average. The majority of SCC cases were diagnosed at the in situ or localized stage (58.1%). API were more likely to be diagnosed with regional or distant stage disease than were other racial/ethnic groups (27.5% and 11.8%, respectively). Males had lower 5-year relative survival than females for all stages of disease. CONCLUSIONS Rates of anal SCC varied by sex, race, and ethnicity. A higher proportion of API were diagnosed at regional/distant stage. Men had lower 5-year survival rates than women. Continued surveillance and additional research are needed to assess the potential impact of the HPV vaccine on the anal cancer burden in the US.

Abstract
PURPOSE Global data on age-specific prevalence of human papillomavirus (HPV) infection overall, and for high-risk HPV types 16 and 18, are essential for the future implementation of HPV prophylactic vaccines for cervical cancer prevention. METHODS A systematic review of peer-reviewed publications was conducted to summarize worldwide data on genital HPV-DNA prevalence in women. Studies with clear descriptions of polymerase chain reaction or hybrid capture detection assays were included. RESULTS A total of 346,160 women were included in 375 studies. Of 134 studies with age-stratified HPV prevalence data (116 low sexual risk populations, 18 high sexual risk populations), over 50% were from Europe and the Middle East (38%) and North America (19%), with smaller proportions from Asia and Australia (21%), Central and South America (11%), and Africa (10%). Across all geographical regions, data on HPV prevalence were generally limited to women over 18 years of age. Consistently across studies, HPV infection prevalence decreased with increasing age from a peak prevalence in younger women (< or =25 years of age). In middle-aged women (35-50 years), maximum HPV prevalence differed across geographical regions: Africa (approximately 20%), Asia/Australia (approximately 15%), Central and South America (approximately 20%), North America (approximately 20%), Southern Europe/Middle East (approximately 15%), and Northern Europe (approximately 15%). Inconsistent trends in HPV prevalence by age were noted in older women, with a decrease or plateau of HPV prevalence in older ages in most studies, whereas others showed an increase of HPV prevalence in older ages. Similar trends of HPV 16 and/or 18 prevalence by age were noted among 12 populations with available data. DISCUSSION Genital HPV infection in women is predominantly acquired in adolescence, and peak prevalence in middle-aged women appears to differ across geographical regions. Worldwide variations in HPV prevalence across age appear to largely reflect differences in sexual behavior across geographical regions. Further studies of HPV prevalence in adolescents are needed for all geographic regions.

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

Abstract
PURPOSE This study was designed to determine the prevalence and risk factors for anal squamous intraepithelial lesions and human papillomavirus infection in a rural population of HIV-infected males. METHODS A cross-sectional study was performed. Risk factors were collected. Anal Papanicolaou smear and human papillomavirus screening for oncogenic types were performed. RESULTS Of 211 eligible male patients, 149 (70.6 percent) participated. HIV transmission risk was predominantly males who have sex with males (82 percent). The mean duration of HIV infection was 9.9 years. Ninety (60 percent) males had abnormal anal cytology, including atypical cells of unknown significance 40 (26 percent), low-grade squamous intraepithelial lesions 28 (19 percent), and high-grade squamous intraepithelial lesions 22 (15 percent). Human papillomavirus was detected in 61 percent. Binary logistic regression adjusted risks for abnormal anal cytology included: males who have sex with males (P<0.001), human papillomavirus infection (P<0.001), history of anogenital warts (P=0.014), and the mean lowest CD4 count (abnormal cytology, 158 (standard deviation, 135), negative cytology, 208 (standard deviation, 180; P=0.017)). Twenty-two patients with high-grade squamous intraepithelial lesions underwent colorectal surgical examination and anoscopy. Two (10 percent) were found to have invasive squamous-cell carcinoma and three (15 percent) others had mass lesions with high-grade squamous intraepithelial lesions. CONCLUSIONS Anal squamous intraepithelial lesions and oncogenic human papillomavirus are highly prevalent in males infected with HIV and living in a rural setting.

Abstract
The improved survival of pediatric recipients of solid organ transplants has prompted increased attention to quality of life issues. In adolescents these include attainment of normal growth and development, and involvement in romantic and sexual relationships. This review focuses on the reproductive health care needs of adolescent solid organ transplant recipients, including issues related to puberty, menstruation, and fertility. Contraceptive options, and the implications of their use by transplant recipients, are described. With close clinical follow up, most currently available hormonal contraceptive methods can be considered, and the impact of drug interactions with immunosuppressants can be minimized by eliminating hormone-free intervals. Monitoring for sexually transmitted infections, including oncogenic Human Papilloma Virus and its sequelae, is especially important for transplant recipients. Comprehensive reproductive health care visits are recommended for all sexually active adolescent solid organ transplant recipients.

Abstract
This study was performed to establish the prevalence of perianal human papillomavirus (HPV) infection in relation to HIV-positivity in a group of men who have sex with men (MSM), and to correlate follow-up data with regard to acquisition and clearance of HPV infection. Data with regard to HPV prevalence and HIV serostatus during two visits were compared. At both visits participants underwent a routine venereological examination and swabs were taken from the perianal region for HPV DNA testing. During both visits HPV types 16, 18, 31, 33 and 52 were significantly more often detected in HIV-positive individuals. Persistence of HPV type 31 at the perianal region was significantly more often seen in HIV-positive MSM (p=0.036) while the incidence of type 16 may be associated with HIV positivity (p=0.059). In HIV-positive MSM significantly more high-risk HPV types were detected at the perianal region.

Abstract
Human papillomavirus (HPV), the primary cause of cervical cancer, is also associated with the development of anal cancer. Relatively little is known about the epidemiology of anal HPV infection among healthy females and its relationship to cervical infection. We sought to characterize anal HPV infection in a cohort of adult women in Hawaii. Overall, 27% (372 of 1,378) of women were positive for anal HPV DNA at baseline compared with 29% (692 of 2,372) with cervical HPV DNA. Among women with paired anal and cervical samples, anal infection without accompanying cervical infection was observed in 14% (190 of 1,363). Concurrent anal and cervical HPV infections were observed in 13% (178 of 1,363) of women. Women with cervical HPV infection had >3-fold increased risk of concurrent anal infection. Concurrent anal and cervical HPV infection was most prevalent among the youngest women and steadily decreased through age 50 years. By contrast, the prevalence of anal infection alone remained relatively steady in all age groups. Compared with cervical infections, the overall distribution of HPV genotypes in the anus was more heterogeneous and included a greater proportion of nononcogenic types. A high degree of genotype-specific concordance was observed among concurrent anal and cervical infections, indicating a common source of infection. Nevertheless, the association of anal intercourse with anal HPV infection was limited to those women without accompanying cervical infection. The relationship of anal to cervical infection as described in this study has implications for the development of anal malignancies in women.

Abstract
Human papillomavirus (HPV) is the most common sexually transmitted disease in both men and women. Prevalence rates are the highest for adolescents. Despite the high prevalence rates, sequelae of genital warts, dysplasia, and cancer are rare developments. Knowledge about the natural history, virology, and cancerous transformation has lead to improved viral detection, including the use of HPV DNA detection tests, screening efforts for HPV-related precancerous and cancerous lesions, and clinical interventions and treatments, including both therapeutic and prophylactic vaccinations.

Abstract
PURPOSE OF REVIEW We review the recent literature on anogenital neoplasms in AIDS, with emphasis on cancers associated with HPV infection. Immune reactivity to HPV as well as novel immunotherapeutic and preventative strategies are discussed. RECENT FINDINGS Many AIDS-associated neoplasms are associated with HPV infection. Whether cervical cancer is truly an AIDS-associated neoplasm has recently been questioned, while the association of anal cancer with AIDS in both males and females is more convincing. Recent reports cast doubt on the efficacy of HAART therapy for HPV-induced anogenital neoplasms, despite efficacy in improving disease caused by other infectious agents. We include here new data on humoral and cellular immune responses to HPV. VLP serology has been reported to be associated with outcome of cervical cancer. VLP seropositivity has been reported to be a favorable prognostic sign in women with HPV 16 positive cervical carcinoma. Several investigators have questioned the immunogenicity of the oncogenic HPV type 16 compared with other HPV types. It has recently been found that in HIV-infected patients, lymphoproliferative cellular immune responses (CMI) to HPV 16 peptides are not associated with CD4 counts, whereas responses to recall antigens and mitogens are associated with CD4 counts. CD4 + T cells may not be responsible for protective cellular immune responses to HPV. VLP serology and CMI responses may be the future intermediate surrogate biomarkers for HPV-associated anogenital neoplasia trials. Several new therapeutic vaccine strategies for management of HPV-induced neoplasia are reviewed. SUMMARY Most anogenital neoplasms occurring with increased frequency in patients with HIV/AIDS are associated with HPV infections. Current treatment strategies are not effective in clearing anogenital HPV infection and need improvement. Immunotherapy with novel vaccines will provide both prevention and therapy for these common malignancies.

Abstract
The concordance of the prevalence of human papillomavirus (HPV) DNA in 188 sex workers in five different locations was investigated. HPV was found in 43.6% of the women, and its prevalence at genital sites was similar. Prevalence was highest among women aged 20 years or younger but declined thereafter in specimens from all anogenital sites.

Abstract
Science has made great strides in understanding the management of the many gynecologic conditions that affect HIV-positive women with an increased frequency. As HIV-infected women's life expectancy continues to lengthen, new treatments are necessary for recurring conditions, such as lower genital tract neoplasias. The medical field has much to learn about the interaction between sex steroids, HIV-infection, and the immune system. As knowledge grows, clinicians will be better equipped to counsel women about contraceptive issues, pregnancy, and menopause.
