High-risk human papillomavirus infection among women living with HIV in Latin America and the Caribbean: A systematic review and meta-analysis

We carried out a systematic review to summarize available data regarding prevalence of high-risk human papillomavirus (HR-HPV) among women living with HIV (WLHIV) in Latin America and the Caribbean (LAC). A literature search in PubMed and LILACS was conducted and supplemented with cross-referencing and grey literature. The primary outcome was prevalence of HR-HPV by age as a major determinant of HPV infection. Pooled prevalence and weighted averages were obtained. A random effects meta-analysis conducted for HPV- and HIV-associated factors. In total, 6157 women from 19 cross-sectional studies were included. Weighted prevalence of HR-HPV in WLHIV was 51.0% (95% CI 42.8-59.1, I2 = 97.4%) with a bimodal trend by age. No association between antiretroviral therapy and HR-HPV prevalence was observed, but low CD4 cell count was associated (PR 1.64, 95% CI 1.07-2.52). Although not significant, a higher HR-HPV prevalence was observed with Hybrid Capture 2 versus PCR. The high prevalence of HR-HPV among WLHIV in LAC underlines the need for improved cervical cancer prevention and early detection in this vulnerable population. Moreover, the high prevalence across age groups, and particularly in young women, deserves careful consideration for defining target populations of HPV-based screening and HPV immunization programs.

Prevalence of anal human papillomavirus infection in patients with human immunodeficiency virus infection: A systematic review

BACKGROUND

Human papillomavirus (HPV) is one of the most common sexually transmitted viruses nowadays.

AIM

To analyze the prevalence of HPV infection in human immunodeficiency virus (HIV)-positive patients and the risk factors associated with this infection through a review of studies published in the period from January 2010 to April 2020.

METHODS

A total of 384 articles were initially identified in our searches, of which ten were selected according to previously defined eligibility criteria.

RESULTS

Anal intercourse, absence of condom use, multiple partners, other specific sexual and life habits, and HIV infection are among the risk factors associated with anal HPV infection.

CONCLUSION

In general, there is a higher prevalence of anal HPV infection among HIV-positive patients, mostly in individuals over 30 years old, those with multiple partners, those who had an early homosexual debut, and cigarette, alcohol, and drug users.

High-risk human papillomavirus and cervical lesions among women living with HIV/AIDS in Brazilian Amazon, Brazil

Objective

The goal of this study was to determine the prevalence of human papillomavirus infection infection and cervical lesions and its associated factors among HIV infected women attending an AIDS clinic in Amazonas state, Brazil.

Methods

Cross-sectional study. Women attending an AIDS clinic in the city of Manaus between March and December 2011 for gynecological examination were invited to participate. Enrolled patients answered a standardized interview including demographical, behavioral, and clinical data. Additionally, patients underwent a gynecological evaluation with collection of cervical samples for cytological analysis and high-risk human papillomavirus infection hybrid capture. A blood sample was also obtained to determine CD4 and viral load levels.

Results

A total of 310 (82.9%) women participated in the study. High-risk human papillomavirus infection was detected in 191 (61.6%) cases; 24 (13.5%) had low-grade squamous intraepithelial lesion (SIL) and 4 (2.2%) high-grade SIL. No invasive cervical cancer was diagnosed. Median age was 32 (interquartile range (IQR): 27–38) years and median of education was 8.5 (IQR 4–11) years of schooling and 56.1% had a monthly income up to US$180. In multivariate analysis, being less than 30 years old [OR = 1.7 (95% CI: 1.2–2.4, p = 0.005)], high-grade SIL [OR = 6.5 (95% CI: 1.6–23.0, p = 0.009)], and CD4 counts <200 cells/mm³ [OR = 1.6 (95% CI: 1.2–2.0, p < 0.001)] were associated with high risk human papillomavirus infection infection.

Conclusions

In the present study high-risk human papillomavirus infection was frequent and it was associated to high-SIL. These results show the importance of gynecologic examinations in routine care and follow-up required by those who present with cervical lesions.
