Neovaginal and Anal High-Risk Human Papillomavirus DNA Among Thai Transgender Women in Gender Health Clinics

Human Papillomavirus Positivity at 3 Anatomical Sites Among Transgender Women in Central Brazil

BACKGROUND

Transgender women (TGW) are susceptible to the acquisition of sexually transmitted infections (STIs), including human papillomavirus (HPV). Nonetheless, the exact data for this population are scarce. We estimated HPV positivity at the anal, genital, and oral sites among TGW and also identified the related characteristics and behaviors that could be risk factors for HPV infection in a sample of TGW in Brazil. Furthermore, we characterized the site-specific HPV genotypes among those who were positive for HPV at these 3 sites.

METHODS

A cross-sectional study was conducted on TGW in Goiânia City (Central-Midwest region), Brazil, between April 2018 and August 2019. Respondent-driven sampling was applied for recruitment. Next, self-collected anal, genital, and oral samples were examined for HPV DNA using polymerase chain reaction (SPF-10 primer). Human papillomavirus genotypes were identified in 12 TGW.

RESULTS

In the TGW included in the study, the anal, genital, and oral HPV positivity values were 77.2% (95% confidence interval [CI], 67.3%-84.6%), 33.5% (95% CI, 26.1%-48.9%), and 10.9% (95% CI, 5.8%-17.0%), respectively. In addition, the majority of 12 participants who tested for HPV had multiple genotypes. HPV-52 was the most prevalent genotype identified at the anal (66.6%) and genital (40.0%) sites, whereas HPV-62 and HPV-66 were the most common at the oral site (25.0%).

CONCLUSIONS

A high HPV positivity was observed among TGW. Therefore, additional epidemiological studies on HPV genotypes should generate health intervention information, including the prevention, diagnosis, and treatment of sexually transmitted infections.

Distinct mucosal and systemic immunological characteristics in transgender women potentially relating to HIV acquisition

Transgender women (TGW) are disproportionally affected by HIV infection, with a global estimated prevalence of 19.9%, often attributed to behavioral risk factors, with less known about biological factors. We evaluated potential biological risk factors for HIV acquisition in TGW at the sites of viral entry by assessing immune parameters of the neovaginal surface and gut mucosa. The neovagina in TGW, compared with the vagina in cisgender women (CW), shows distinct cell composition and may pose a more inflammatory environment, evidenced by increased CD4+ T cell activation and higher levels of soluble markers of inflammation (C-reactive protein, soluble CD30). Increased inflammation may be driven by microbiome composition, as shown by a greater abundance of Prevotella and a higher Shannon Diversity Index. In addition, we have observed higher frequency of CD4+CCR5+ target cells and decreased DNA methylation of the CCR5 gene in the gut mucosa of TGW compared with CW and men who have sex with men, which was inversely correlated with testosterone levels. The rectal microbiome composition in TGW appears to favor a proinflammatory milieu as well as mucosal barrier disruption. Thus, it is possible that increased inflammation and higher frequencies of CCR5-expressing target cells at sites of mucosal viral entry may contribute to increased risk of HIV acquisition in TGW, with further validation in larger studies warranted.

Neovaginal Human Papillomavirus Prevalence in Transfeminine Individuals: A Systematic Review

OBJECTIVE

To assess the prevalence of high-risk human papillomavirus (hrHPV) and human papillomavirus (HPV)-associated abnormalities in the neovaginas of postvaginoplasty transfeminine patients to inform potential HPV-screening guidelines for this patient population.

DATA SOURCES

MEDLINE, ClinicalTrials.gov , the Cochrane Library, Scopus, and Google Scholar were searched through September 30, 2022.

METHODS OF STUDY SELECTION

The population included transfeminine individuals who had undergone vaginoplasty with an outcome of subsequent positive HPV diagnosis or HPV-related lesions. Randomized clinical trials, cohort studies, cross-sectional studies, and case reports available in English were included in the analysis. Identified articles were doubly screened, and accepted articles were doubly extracted.

TABULATION, INTEGRATION, AND RESULTS

Of 59 abstracts identified, 30 were screened for eligibility, of which 15 met the criteria for review. Included studies were assessed for vaginoplasty procedure type, time elapsed between vaginoplasty and HPV testing, HPV type, location and manner of sample collection, method of HPV diagnosis, and classification and location of HPV-associated neovaginal lesions. Studies were assigned a grade of evidence of very low, low, moderate, or high based on study design, precision, directness, and risk of bias. Prevalence of neovaginal hrHPV ranged from 8.3% to 20% in identified studies, and per-study prevalence of HPV-related neovaginal abnormalities ranged from 0% to 8.3% in patients.

CONCLUSION

The current body of research demonstrates that, after vaginoplasty, transfeminine individuals may develop neovaginal HPV infection with associated cytologic abnormalities or grossly apparent lesions. In some included studies, neovaginal HPV-associated lesions were highly advanced before they were identified. A small number of studies assessed neovaginal HPV prevalence in transfeminine individuals, with hrHPV prevalence ranging from 8.3% to 20%. However, broader conclusions about neovaginal HPV prevalence are limited by a lack of high-grade evidence in the existing literature. More rigorous prevalence research is needed to inform preventative care guidelines for transfeminine individuals at risk of developing HPV-related neovaginal complications.

Anatomical and sexual health considerations among transfeminine individuals who have undergone vaginoplasty: A review

As acceptance of transgender and gender diverse individuals continues to increase, gender-affirming surgery, a cornerstone in the management of gender dysphoria, is becoming more readily available. HIV and sexually transmitted infections (STIs) disproportionately affect these populations, but there are limited epidemiologic and management data on STIs in people who have undergone gender-affirming genital surgery such as vaginoplasty. This review will provide clinicians with anatomical details about the various vaginoplasty procedures currently being performed, complications associated with these procedures, and an overview of the current literature describing HIV/STI epidemiology among transfeminine individuals who have undergone vaginoplasty.
