ABSTRACT HIV-positive women have a high prevalence of human papillomavirus (HPV) infection and are infected with a broader range of HPV types than HIV-negative women. It is not known to what extent these different types are associated with high-grade squamous intraepithelial lesions (HSIL) and cancer.
Meta-analysis of HPV type-specific prevalence among HIV-positive women, stratified by geographical region and by cervical cytology: normal, atypical squamous cells of undetermined significance/low-grade squamous intraepithelial lesions (ASCUS/LSIL) or HSIL.
In 20 studies, 5578 HIV-positive women were identified, largely from North America but also Africa, Asia, Europe and South/Central America. For 3230 with no cytological abnormalities, prevalence was 36.3% for any HPV and 11.9% for multiple HPV types. The six most common high-risk HPV types were 16 (4.5%), 58 (3.6%), 18 (3.1%), 52 (2.8%), 31 (2.0%) and 33 (2.0%). HPV16 was also the most common type in 2053 HIV-positive women with ASCUS/LSIL and 295 with HSIL. Those with HSIL were significantly less likely to be infected with HPV16 (odds ratio, 0.6; 95% confidence interval, 0.4-0.7) than the general female population with HSIL. In contrast, HIV-positive women with HSIL were significantly more likely to be infected with HPV types 11, 18, 33, 51, 52, 53, 58 and 61, and with multiple HPV types.
The proportion of HIV-positive women with HPV16 rose with increasing severity of cervical lesions. Nevertheless, HPV16 remained underrepresented in HIV-positive women with HSIL, who showed a higher proportion of other HPV types and multiple types compared with the general female population with HSIL.

    ABSTRACT: Background Yunnan has one of the oldest and the most severe human immunodeficiency virus (HIV) epidemics in China. We conducted an observational study to evaluate the human papillomavirus (HPV) genotype distribution in relation to cervical neoplastic disease risk among HIV-infected women in Yunnan.Methods We screened 301 HIV-infected non-pregnant women in Mangshi prefecture in Yunnan province. All consenting participants underwent simultaneous and independent assessment by cervical cytology, colposcopy-histopathology, and HPV genotyping. Unadjusted and multivariable-adjusted multinomial logistic regression analysis was conducted to evaluate factors associated with single or multiple carcinogenic HPV genotypes.ResultsHPV genotypes were present in 43.5% (131/301) overall, and carcinogenic HPV genotypes were present in 37.5% (113/301) women. Among women with carcinogenic HPV genotypes, 80 (70.8% of 113) had a single carcinogenic HPV type, while 33 (29.2%) women had multiple (2 or more) carcinogenic HPV types. Overall, the most common carcinogenic HPV types were HPV52 (7.3%), HPV58 (6.6%), HPV18 (6.3%), HPV16 (6.0%), and HPV33 (5.3%). In women with cervical precancerous lesions (i.e., high-grade squamous intraepithelial lesions [HSIL] on cytology or cervical intraepithelial neoplasia grades 2 or worse [CIN2+] detected on colposcopy-histology), the most commonly detected genotypes were HPV16 (28.6%), HPV52 (25.0%), HPV58 (17.9%), HPV18 (10.7%) and HPV31 (10.7%). Increasing age was an independent risk factor associated with presence of single carcinogenic HPV types (adjusted odds ratio: 1.04, 95%CI: 1.01-1.07, p¿=¿0.012) but not with the presence of multiple carcinogenic types in the multivariable-adjusted models.Conclusions As HIV-infected women continue to live longer on antiretroviral therapy in China, it will be increasingly important to screen for, and prevent, HPV-associated cervical cancer in this population, especially given the wide diversity and multiplicity of HPV genotypes.

    ABSTRACT: Cervical cancer is the second most common cancer in women worldwide. It represents one of the most challenging public health problems in developing countries. HIV-infected women have a higher risk of cervical cancer which is an AIDS defining cancer. Cervical cancer treatment in HIV-infected and non-infected women is the same. HIV naive women must be prescribed combination antiretroviral therapy at the moment of HIV cancer diagnosis. A close collaboration between oncologist and infectiologist is mandatory to optimize HIV treatment. Among HIV-infected women, PAP-smear screening for early detection and treatment of precancerous cervical lesions is recommended. HPV vaccination is also recommended with the same efficacy and safety profile as the general population.

    ABSTRACT: The prevalence of High-Risk Human papilloma virus (HR-HPV), a necessary cause of invasive cervical cancer (ICC) is relatively high in HIV infected women. Gaps exist in our knowledge of the optimal approaches for managing women who have HR-HPV with normal cervical cytology (NCC) particularly in settings of HIV infection.
