High resolution anoscopy findings for men who have sex with men: Inaccuracy of anal cytology as a predictor of histologic high-grade anal intraepithelial neoplasia and the impact of HIV serostatus

We compared the pathological diagnoses obtained by anal Papanicolaou (Pap) smear with those obtained by anal biopsy or by surgical excision for 153 men who have sex with men (MSM). Analysis of these paired specimens showed that anal Pap smears were an inaccurate predictor of high-grade anal dysplasia, regardless of human immunodeficiency virus (HIV) serostatus. The presence of any abnormal anal cytological finding indicates a potential for high-grade dysplasia on histological examination of MSM.

Infrared coagulator treatment of high-grade anal dysplasia in HIV-infected individuals: an AIDS malignancy consortium pilot study.

Objective:To evaluate prospectively the safety of the infrared coagulator (IRC) as a treatment for anal high-grade squamous intraepithelial lesions (HSILs) in HIV-infected individuals and to seek preliminary evidence for efficacy. Methods:HIV-infected patients with ≤3 biopsy-proven internal anal HSILs received office-based treatment with the IRC at participating AIDS Malignancy Consortium sites. Treatments were performed during high-resolution anoscopy (HRA) under local anesthesia. Patients were reevaluated at 3 months, and persistent lesions could be retreated. Patients were evaluated every 3 months for a year with anal cytology and HRA with biopsy. Human papillomavirus (HPV) DNA was measured at baseline and at follow-up using MY09/MY11 L1 polymerase chain reaction. Results:A total of 44 HSILs were treated from 16 men and 2 women. HPV 16 was the most common HPV type identified. There was no consistent change in HPV type or viral load in patients before and after treatment with the IRC. No procedure-related severe adverse events were reported. Twelve patients reported mild or moderate anal/rectal pain or bleeding. Conclusions:The IRC is a well-tolerated method of treating discrete anal canal HSILs in HIV-infected patients. A larger study to characterize its efficacy better in the management of HSILs in HIV-infected individuals is warranted.

Safety and efficacy of topical Cidofovir to treat high-grade perianal and vulvar intraepithelial neoplasia in HIV-positive men and women

Objective:To evaluate the safety and efficacy of topical cidofovir for treatment of high-grade squamous perianal intraepithelial neoplasia (PAIN) and vulvar intraepithelial neoplasia (VIN) lesions in HIV-positive individuals. Design:Phase IIa prospective multicenter trial conducted at eight clinical sites through the AIDS Malignancy Consortium. Methods:HIV-positive patients with biopsy-proven high-grade PAIN that was at least 3u200acm2 were enrolled. PAIN biopsy specimens were assessed for human papillomavirus (HPV) using PCR and type-specific HPV probing. Participants applied 1% topical cidofovir to PAIN and VIN (if present) for six 2-week cycles. Results were designated as complete response (CR), partial response (PR) (>50% reduction in size), stable disease, or progressive disease (PD). Results:Twenty-four men and nine women (eight with high-grade VIN as well) were enrolled. Mean age was 44 years and mean CD4+ cell count was 412u200acells/&mgr;l. HPV DNA (most commonly HPV16) was detected in all pretreatment study specimens. Twenty six (79%) participants completed treatment per protocol: CR, five (15%); PR, 12 (36%), stable disease, seven (21%); PD, two (6%) (one with a superficially invasive cancer and one with new area of high-grade PAIN). Treatment was well tolerated with most common adverse events being mild to moderate affecting lesional skin: pain/burning/irritation (25 patients) and ulceration (13 patients). Conclusion:Topical cidofovir had 51% efficacy in the short-term treatment of high-grade PAIN and VIN with acceptable toxicity in HIV-positive individuals. Randomized control studies with more prolonged treatment courses and longer follow-up to assess the durability of the response are needed.

Frequency of Occult High-Grade Squamous Intraepithelial Neoplasia and Invasive Cancer within Anal Condylomata in Men Who Have Sex with Men

Human papillomavirus causes anal condylomata, high-grade anal intraepithelial neoplasia, and anal squamous cell cancer. We found high-grade intraepithelial neoplasia or squamous cell cancer in 75 (47%) of 159 HIV-seropositive men who have sex with men (MSM) and in 42 (26%) of 160 HIV-seronegative MSM with anal condylomata meriting surgery (P<.001, determined by use of the chi(2) test). Anal condylomata in MSM often harbor high-grade intraepithelial neoplasia and squamous cell cancer.

Comparing self- and provider-collected swabbing for HPV DNA testing in female-to-male transgender adult patients: a mixed-methods biobehavioral study protocol

BackgroundCervical cancer, nearly all cases of which are caused by one of several high-risk strains of the human papillomavirus (hr-HPV), leads to significant morbidity and mortality in individuals with a cervix. Trans masculine (TM) individuals were born with female reproductive organs and identify as male, man, transgender man, or another diverse gender identity different from their female assigned sex at birth. Routine preventive sexual health screening of TM patients is recommended, including screening for cervical cancer and other sexually transmitted infections (STIs); however, as many as one in three TM patients are not up-to-date per recommended U.S. guidelines. Among cisgender (non-transgender) women, self-swab hr.-HPV DNA testing as a primary cervical cancer screening method and self-swab specimen collection for other STIs have high levels of acceptability. No study has yet been conducted to compare the performance and acceptability of self- and provider-collected swabs for hr.-HPV DNA testing and other STIs in TM patients.MethodsThis article describes the study protocol for a mixed-methods biobehavioral investigation enrolling 150 sexually active TM to (1) assess the clinical performance and acceptability of a vaginal self-swab for hr.-HPV DNA testing compared to provider cervical swab and cervical cytology, and (2) gather acceptability data on self-collected specimens for other STIs. Study participation entails a one-time clinical visit at Fenway Health in Boston, MA comprised of informed consent, quantitative assessment, venipuncture for syphilis testing and HIV (Rapid OraQuick) testing, randomization, collection of biological specimens/biomarkers, participant and provider satisfaction survey, and qualitative exit interview.

Condylomata Acuminata (Anogenital Warts) Contain Accumulations of HIV-1 Target Cells That May Provide Portals for HIV Transmission

100. The primary study outcomes are concordance (kappa statistic) and performance (sensitivity and specificity) of self-collected vaginal HPV DNA specimens vs provider-collected cervical HPV swabs as a gold standard.DiscussionThis study addresses critical gaps in current clinical knowledge of sexual health in TM patients, including comparing alternative strategies for screening and diagnosis of cervical cancer, hr.-HPV, and other STIs. Findings have implications for improving the delivery of sexual health screening to this often overlooked and underserved patient population. Less-invasive patient-centered strategies may also generalize to other at-risk cisgender female populations that face barriers to timely and needed STI and cervical cancer screening.Trial registrationClinicalTrials.gov ID: NCT02401867

Test performance and acceptability of self- versus provider-collected swabs for high-risk HPV DNA testing in female-to-male trans masculine patients

BackgroundnCondylomata acuminata (anogenital warts [AGWs]) are prevalent in human immunodeficiency virus (HIV)-infected individuals and sexually active populations at risk for HIV acquisition and have been associated with HIV transmission. We compared AGW specimens to control tissue specimens for abundance, types, and location of HIV target cells and for susceptibility to HIV infection in vitro, to provide biologic evidence that AGWs facilitate HIV transmission.nnnMethodsnWe used immunohistologic staining to identify HIV target cells in AGW and control specimens. We also inoculated HIV in vitro into AGW and control specimens from HIV-negative men and assessed infection by means of TZM-bl and p24 assays.nnnResultsnCD1a+ dendritic cells, CD4+ T cells, and macrophages were significantly more abundant in the epidermis of AGW specimens than control specimens. These HIV target cells also often appeared in large focal accumulations in the dermis of AGW specimens. Two of 8 AGW specimens versus 0 of 8 control specimens showed robust infection with HIV in vitro.nnnConclusionsnCompared with normal skin, AGWs contain significantly higher concentrations of HIV target cells that may be susceptible to HIV infection. Condylomata may thus promote HIV transmission, especially in the setting of typical lesion vascularity and friability. Prevention or treatment of AGWs may decrease the sexual transmission of HIV.

How HIV infection and its treatment affects the cardiovascular system: what is known, what is needed.

Background High-risk human papillomavirus (hrHPV) causes virtually all cervical cancers. Trans masculine (TM) people (those assigned female at birth who identify with a gender other than female) have low uptake of conventional cervical cancer screening. Self-collected hrHPV DNA testing has high levels of acceptability among cisgender (non-transgender) females and may support increased cervical cancer screening uptake in TM individuals. Objective To assess the test performance and acceptability of self-collected vaginal specimens in comparison to provider-collected cervical swabs for hrHPV DNA detection in TM individuals ages 21–64 years. Methods Between March 2015-September 2016, 150 TM participants with a cervix (mean age = 27.5 years; SD = 5.7) completed a one-time study visit comprised of a self-report survey, self-collected vaginal HPV DNA swab, clinician-administered cervical HPV swab, and brief interview on acceptability of clinical procedures. Participants were randomized to complete either self- or provider-collection first to minimize ordering effects. Self- and provider-collected samples were tested for 13 hrHPV DNA types using a DNA Hybridization Assay. The primary outcome variable was the concordance (kappa statistic) and performance (sensitivity, specificity) of self-collected vaginal HPV DNA specimens versus provider-collected cervical HPV swabs as the gold standard. Results Of the 131 participants completing both the self- and provider-collected HPV tests, 21 cases of hrHPV were detected by the provider cervical swab (gold standard; 16.0% hrHPV prevalence); 15 of these cases were accurately detected by the self-collected vaginal swab (71.4% concordance) (Kappa = 0.75, 95% Confidence Interval [CI]: 0.59, 0.92; p<0.001). Compared to the provider-collected cervical hrHPV DNA sample (gold standard), the self-collected vaginal hrHPV DNA test demonstrated a sensitivity of 71.4% (95% CI: 0.52, 0.91; p = 0.0495) and specificity of 98.2% (95% CI: 0.96, 1.00; p<0.0001). Over 90% of participants endorsed a preference for the self-collected vaginal swab over provider-collected cervical swab. Conclusion Self-collected vaginal swabs are highly acceptable to TM as a means to test for hrHPV DNA. Test performance of this self-collection method for hrHPV detection in TM is consistent with previous studies in cisgender females. Self-collected vaginal swab testing for hrHPV DNA represents a reasonable and patient-centered strategy for primary cervical cancer screening in TM patients unwilling to undergo provider collection of specimens via speculum exam.
