Association between HIV Serostatus and premalignant cervical lesions among women attending a cervical cancer screening clinic at a tertiary care facility in southwestern Uganda: a comparative cross-sectional study. BMC Womens Health 2024; 24:266. [PMID: 38678278 PMCID: PMC11055386 DOI: 10.1186/s12905-024-03108-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2023] [Accepted: 04/23/2024] [Indexed: 04/29/2024] Open
Abstract
BACKGROUND Uganda has approximately 1.2 million people aged 15-64 years living with human immunodeficiency virus (HIV). Previous studies have shown a higher prevalence of premalignant cervical lesions among HIV-positive women than among HIV-negative women. Additionally, HIV-infected women are more likely to have human papilloma virus (HPV) infection progress to cancer than women not infected with HIV. We determined the prevalence of premalignant cervical lesions and their association with HIV infection among women attending a cervical cancer screening clinic at Mbarara Regional Referral Hospital (MRRH) in southwestern Uganda. METHODS We conducted a comparative cross-sectional study of 210 women aged 22-65 years living with HIV and 210 women not living with HIV who were systematically enrolled from March 2022 to May 2022. Participants were subjected to a structured interviewer-administered questionnaire to obtain their demographic and clinical data. Additionally, Papanicolaou smears were obtained for microscopy to observe premalignant cervical lesions. Multivariate logistic regression was performed to determine the association between HIV status and premalignant cervical lesions. RESULTS The overall prevalence of premalignant cervical lesions in the study population was 17% (n = 72; 95% C.I: 14.1-21.4), with 23% (n = 47; 95% C.I: 17.8-29.5) in women living with HIV and 12% (n = 25; 95% C.I: 8.2-17.1) in women not living with HIV (p < 0.003). The most common premalignant cervical lesions identified were low-grade squamous intraepithelial lesions (LSIL) in both women living with HIV (74.5%; n = 35) and women not living with HIV (80%; n = 20). HIV infection was significantly associated with premalignant lesions (aOR: 2.37, 95% CI: 1.27-4.42; p = 0.007). CONCLUSION Premalignant cervical lesions, particularly LSILs, were more common in HIV-positive women than in HIV-negative women, highlighting the need to strengthen the integration of cervical cancer prevention strategies into HIV care programs.

Abstract
Viral co-infections, in which a host is infected with multiple viruses simultaneously, are common in the human population. Human viral co-infections can lead to complex interactions between the viruses and the host immune system, affecting the clinical outcome and posing challenges for treatment. Understanding the types, mechanisms, impacts, and identification methods of human viral co-infections is crucial for the prevention and control of viral diseases. In this review, we first introduce the significance of studying human viral co-infections and summarize the current research progress and gaps in this field. We then classify human viral co-infections into four types based on the pathogenic properties and species of the viruses involved. Next, we discuss the molecular mechanisms of viral co-infections, focusing on virus-virus interactions, host immune responses, and clinical manifestations. We also summarize the experimental and computational methods for the identification of viral co-infections, emphasizing the latest advances in high-throughput sequencing and bioinformatics approaches. Finally, we highlight the challenges and future directions in human viral co-infection research, aiming to provide new insights and strategies for the prevention, control, diagnosis, and treatment of viral diseases. This review provides a comprehensive overview of the current knowledge and future perspectives on human viral co-infections and underscores the need for interdisciplinary collaboration to address this complex and important topic.

Abstract
BACKGROUND Genital HPV infection is recognized worldwide as one of the most common, if not the most common, sexually transmitted infection. Several studies have shown a higher prevalence of HPV infection in women living with HIV (WLWH). We aimed to determine the prevalence of HPV, the circulating genotypes, and its association with risk factors among Algerian WLHIV. METHODS Cervical specimens were collected from 100 WLHIV. The detection of HPV infection was performed by Roche Linear Array test. RESULTS The overall prevalence of HPV infection was determined at 32%, all including high risk HPV (HR-HPV). We found a great diversity of HR-HPV genotypes, the most common individually were HPV52, HPV16, HPV18 and HPV58, The highest prevalence was found in groups of genotype 52, 25%. HPV16 and 18 were less common (16%). Cervical cytology was abnormal in 66% (81.3% in the HPV + population), with a predominance of inflammatory lesions (75% HPV +), The most important determining risk factor for HPV infection in this series was a low CD4 T cell count <200/mm3 found in 72% of the HPV positive participants. CONCLUSION Our study is an initial database, to be completed by a multicenter study to determine the most frequent genotypes in Algerian WLHIV, in order to discuss the introduction of the vaccine against HPV in Algeria, especially among WLHIV.

Variations in Genes Encoding Human Papillomavirus Binding Receptors and Susceptibility to Cervical Precancer. Cancer Epidemiol Biomarkers Prev 2023; 32:1190-1197. [PMID: 37410084 PMCID: PMC10472094 DOI: 10.1158/1055-9965.epi-23-0300] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2023] [Revised: 06/04/2023] [Accepted: 06/30/2023] [Indexed: 07/07/2023] Open
Abstract
BACKGROUND Cervical cancer oncogenesis starts with human papillomavirus (HPV) cell entry after binding to host cell surface receptors; however, the mechanism is not fully known. We examined polymorphisms in receptor genes hypothesized to be necessary for HPV cell entry and assessed their associations with clinical progression to precancer. METHODS African American women (N = 1,728) from the MACS/WIHS Combined Cohort Study were included. Two case-control study designs were used-cases with histology-based precancer (CIN3+) and controls without; and cases with cytology-based precancer [high-grade squamous intraepithelial lesions (HSIL)] and controls without. SNPs in candidate genes (SDC1, SDC2, SDC3, SDC4, GPC1, GPC2, GPC3, GPC4, GPC5, GPC6, and ITGA6) were genotyped using an Illumina Omni2.5-quad beadchip. Logistic regression was used to assess the associations in all participants and by HPV genotypes, after adjusting for age, human immunodeficiency virus serostatus, CD4 T cells, and three principal components for ancestry. RESULTS Minor alleles in SNPs rs77122854 (SDC3), rs73971695, rs79336862 (ITGA6), rs57528020, rs201337456, rs11987725 (SDC2), rs115880588, rs115738853, and rs9301825 (GPC5) were associated with increased odds of both CIN3+ and HSIL, whereas, rs35927186 (GPC5) was found to decrease the odds for both outcomes (P value ≤ 0.01). Among those infected with Alpha-9 HPV types, rs722377 (SDC3), rs16860468, rs2356798 (ITGA6), rs11987725 (SDC2), and rs3848051 (GPC5) were associated with increased odds of both precancer outcomes. CONCLUSIONS Polymorphisms in genes that encode binding receptors for HPV cell entry may play a role in cervical precancer progression. IMPACT Our findings are hypothesis generating and support further exploration of mechanisms of HPV entry genes that may help prevent progression to cervical precancer.

Abstract
BACKGROUND Women with HIV are more often infected with human papillomavirus (HPV) and are more prone to develop precancerous cervical lesions (squamous intraepithelial lesions, SIL) and invasive cervical cancer (ICC) than HIV-negative women. OBJECTIVE This scoping-review analyses the impact of HIV on HPV prevalence, incidence and evolution to SIL and ICC. METHODS We selected all PubMed systematic reviews and meta-analyses published between January 2000 and July 2021 reporting data about HPV, cervical intraepithelial neoplasia (CIN), SIL and ICC prevalence, incidence and evolution in women with HIV. A hypothetical model comparing the history of HPV infection in HIV-negative, combined antiretroviral therapy (cART)-treated and -untreated women with HIV was built. RESULTS Data from 11 meta-analyses and 10 systematic reviews were selected, which included between 770 and 236 127 women with HIV. Women with HIV have a 3 to 6 times higher risk of being infected by HPV, of progression to high-grade SIL (HSIL) and to ICC. These risks are exacerbated when the CD4 cell counts are low and when they are not using cART, whereas these risks are reduced by 20%-30% when they are optimally treated with cART and have had a suppressed HIV viral load for at least 2 years. In our model, we illustrated that optimal HIV treatment and preventing HIV reduce the number of ICC cases by 2.5 and 6 times, respectively. CONCLUSIONS Optimal treatment and care of HIV patients are essential to reduce their prevalence of ICC, as are preventive strategies which include HPV vaccination, cervical cancer screening strategies and treatment of HSIL.

Abstract
BACKGROUND Worldwide, a significant proportion of head and neck cancers is attributed to the Human papillomavirus (HPV). It is imperative that we acquire a solid understanding of the natural history of this virus in head and neck squamous cell carcinoma (HNSCC) development. Our objective was to investigate the role of sexual behaviour in the occurrence of HNSCC in the French West Indies. Additionally, we evaluated the association of high risk of HPV (Hr-HPV) with sexual behaviour in risk of cancer. METHODS We conducted a population-based case-control study (145 cases and 405 controls). We used logistic regression models to estimate adjusted odds-ratios (OR), and their 95% confidence intervals (CI). RESULTS Compared to persons who never practiced oral sex, those who practiced at least occasionally had a lower HNSCC risk. First sexual intercourse after the age of 18 year was associated with a 50% reduction of HNSCC risk, compared to those who began before 15 years. HNSCC risk was significantly reduced by 60% among persons who used condoms at least occasionally. The associations for ever condom use and oral sex were accentuated following the adjustment for high-risk HPV (Hr-HPV). Oral Hr-HPV was associated with several sexual behaviour variables among HNSCC cases. However, none of these variables were significantly associated with oral HPV infections in the population controls. CONCLUSION First intercourse after 18 years, short time interval since last intercourse and ever condom use were inversely associated with HNSCC independently of oral Hr-HPV infection. Sources of transmission other than sexual contact and the interaction between HPV and HIV could also play a role in HNSCC etiology.

Abstract
Cervical cancer can be eradicated by 2030 by the implementation of a global strategy involving the vaccination of young girls against human papillomavirus (HPV), screening 70% of women in 30-69 years of age and treating 90% of the women with precancerous lesions. For a country with a large population like India, all the three strategies can be a challenge. There is a need for implementation of a high throughput technology that can be scalable. Cobas 4800, a multiplexed assay based on quantitative polymerase chain reaction technology, identifies HPV 16 and HPV 18 along with the concurrent detection of 12 pooled other high-risk HPV infections. This technology was used to test 10 375 women from the South Indian community for the first time as a feasibility program. Upon testing, high-risk HPV was found in 595 (5.73%) women. A total of 127 women (1.2%) were found to be infected with HPV 16, 36 women (0.34%) with HPV 18 and 382 women (3.68%) with the 12 pooled high-risk HPV and multiple mixed infections were found in 50 women (0.48%). It was observed that there was a high prevalence of high-risk HPV in younger women, 30-40 years of age and a second peak was observed at 46-50 years of age. The second peak had higher mixed infections in the 46-50 years of age and this association was statistically significant. We found that 24/50 (48%) of the multiple mixed high-risk HPV infections were in the age group 46-50 years. The current study is the first attempt from India, on a completely automated platform using Cobas 4800 HPV test in a community screening program. This study shows HPV 16 and HPV 18 infections, when differentiated, can be valuable for risk stratification in community screening program. Women in the perimenopausal age (46-50yrs) showed a higher prevalence of multiple mixed infections, signifying a higher risk.

METHODS We centrally reanalyzed individual-level data from 26 studies reporting HPV prevalence in paired anal and cervical samples by human immunodeficiency virus (HIV) status and age. For women with HIV (WWH) with anal high-grade squamous intraepithelial lesions or worse (HSIL+), we also investigated concurrent cervical cytopathology. RESULTS In HIV-negative women, HPV16 prevalence decreased significantly with age, both at anus (4.3% at 15-24 years to 1.0% at ≥55 years; ptrend = 0.0026) and cervix (7.4% to 1.7%; ptrend < 0.0001). In WWH, HPV16 prevalence decreased with age at cervix (18.3% to 7.2%; ptrend = 0.0035) but not anus (11.5% to 13.9%; ptrend = 0.5412). Given anal HPV16 positivity, concurrent cervical HPV16 positivity also decreased with age, both in HIV-negative women (ptrend = 0.0005) and WWH (ptrend = 0.0166). Among 48 WWH with HPV16-positive anal HSIL+, 27 (56%) were cervical high-risk HPV-positive, including 8 with cervical HPV16, and 5 were cervical HSIL+. CONCLUSIONS Age-specific shifts in HPV16 prevalence from cervix to anus suggest that HPV infections in the anus persist longer, or occur later in life, than in the cervix, particularly in WWH. This is an important consideration when assessing the utility of cervical screening results to stratify anal cancer risk.

Abstract
BACKGROUND Several co-factors for HPV oncogenesis have been proposed, including co-infection with HSV-2. We assessed the relationship between HSV-2 infection and HPV-related outcomes in quadrivalent HPV-vaccinated (qHPV) women living with HIV (WLWH). METHODS In this multi-site study of immunogenicity and efficacy of the qHPV vaccine in WLWH, visits took place at months -3, 0, 2, 6, 12, 18, 24, and annually thereafter. Participants provided clinical data and cervico-vaginal swabs for HPV DNA detection; baseline serum was tested for HSV-2 type-specific antibodies. We used non-parametric statistics to compare HPV-related outcomes by HSV-2 serostatus and use of anti-HSV medication. RESULTS 151 baseline serum samples underwent HSV-2 testing. At baseline, median age was 39 years, median CD4 count was 500 cells/mm3, and 70% had an HIV viral load of <50 copies/mL. Baseline HSV-2 seroprevalence was 76.2%. HSV-2 seropositivity was associated with increased age (p = 0.006). Controlling for age and median CD4 count, HSV-2 seropositivity was not associated with HPV incidence, persistence, and precancerous lesions. The use of anti-HSV medications was associated with higher odds of HSIL cytology (OR = 3.35, 95% CI = 1.03,11.26) and a greater number of HPV types detected (OR = 1.18, 95% CI = 1.00,1.39). Results were similar in sensitivity analyses using an index value of 3.5. The presence of HSV lesions during the study was not associated with HPV outcomes. CONCLUSIONS HSV-2 seropositivity was common in this cohort of WLWH in Canada but was not associated with multiple measures of HPV incidence, persistence, and precancerous lesions. However, the use of anti-HSV medications was associated with HSIL cytology and number of HPV types detected.

Abstract
Human papillomavirus (HPV), a common sexually transmitted virus infecting mucosal or cutaneous stratified epithelia, is implicated in the rising of associated cancers worldwide. While HPV infection can be cleared by an adequate immune response, immunocompromised individuals can develop persistent, treatment-refractory, and progressive disease. Primary immunodeficiencies (PIDs) associated with HPV-related disease include inborn errors of GATA, EVER1/2, and CXCR4 mutations, resulting in defective cellular function. People living with secondary immunodeficiency (e.g. solid-organ transplants recipients of immunosuppression) and acquired immunodeficiency (e.g. concurrent human immunodeficiency virus (HIV) infection) are also at significant risk of HPV-related disease. Immunocompromised people are highly susceptible to the development of cutaneous and mucosal warts, and cervical, anogenital and oropharyngeal carcinomas. The specific mechanisms underlying high-risk HPV-driven cancer development in immunocompromised hosts are not well understood. Current treatments for HPV-related cancers include surgery with adjuvant chemotherapy and/or radiotherapy, with clinical trials underway to investigate the use of anti-PD-1 therapy. In the setting of HIV co-infection, persistent high-grade anal intraepithelial neoplasia can occur despite suppressive antiretroviral therapy, resulting in an ongoing risk for transformation to overt malignancy. Although therapeutic vaccines against HPV are under development, the efficacy of these in the setting of PID, secondary- or acquired- immunodeficiencies remains unclear. RNA-based therapeutic targeting of the HPV genome or mRNA transcript has become a promising next-generation therapeutic avenue. In this review, we summarise the current understanding of HPV pathogenesis, immune evasion, and malignant transformation, with a focus on key PIDs, secondary immunodeficiencies, and HIV infection. Current management and vaccine regimes are outlined in relation to HPV-driven cancer, and specifically, the need for more effective therapeutic strategies for immunocompromised hosts. The recent advances in RNA-based gene targeting including CRISPR and short interfering RNA (siRNA), and the potential application to HPV infection are of great interest. An increased understanding of both the dysregulated immune responses in immunocompromised hosts and of viral persistence is essential for the design of next-generation therapies to eliminate HPV persistence and cancer development in the most at-risk populations.

Abstract
The human papillomavirus (HPV), commonly documented as the cause of warts, has gained much interest recently due to its possible links to several types of cancer. HPV infection is discussed in this review from multiple angles, including its virology, epidemiology, etiology, immunology, clinical symptoms, and treatment. Recent breakthroughs in molecular biology have led to the development of new methods for detecting and treating HPV in tissue. There is no cure for HPV, and although vaccines are available to prevent infection with the most common HPV viruses, their utilization is limited. Destruction and excision are the primary treatment modalities. This review sheds light on the epidemiology, molecular pathogenesis, the association of several other pathogens with HPV, the latest treatment strategies available to treat the same, and an overview of the progress made and the obstacles still to be overcome in the fight against HPV infection.

Abstract
The East Africa Consortium was formed to study the epidemiology of human papillomavirus (HPV) infections and cervical cancer and the influence of human immunodeficiency virus (HIV) infection on HPV and cervical cancer, and to encourage collaborations between researchers in North America and East African countries. To date, studies have led to a better understanding of the influence of HIV infection on the detection and persistence of oncogenic HPV, the effects of dietary aflatoxin on the persistence of HPV, the benefits of antiretroviral therapy on HPV persistence, and the differences in HPV detections among HIV-infected and HIV-uninfected women undergoing treatment for cervical dysplasia by either cryotherapy or LEEP. It will now be determined how HPV testing fits into cervical cancer screening programs in Kenya and Uganda, how aflatoxin influences immunological control of HIV, how HPV alters certain genes involved in the growth of tumours in HIV-infected women. Although there have been challenges in performing this research, with time, this work should help to reduce the burden of cervical cancer and other cancers related to HIV infection in people living in sub-Saharan Africa, as well as optimized processes to better facilitate research as well as patient autonomy and safety.

Abstract
Anogenital warts caused by human papillomavirus are common in sexual and gender minorities (SGM). The prevalence of, and factors associated with warts were described for SGM with a high burden of HIV in Nigeria. Individuals who reported anal sex with men were enrolled in the TRUST/RV368 cohort. Participants completed an interviewer-led survey, provided biological samples, and had a physical examination. Specific to the Lagos site, clinic staff offered standardized warts treatment services. RDS-weighted multivariable logistic regression was used to estimate the adjusted odds ratios (AORs) and 95% confidence intervals (CIs) for factors potentially associated with anogenital warts. Of 672 enrolled SGM, 478 (71%) engaged in warts services and had complete data. The median age (interquartile range) was 22 (20-26) years, 272 (52%) initiated sex before age 18, and 347 (79%) were cisgender men. Multiple male sexual partners in the previous year were reported by 448 (90%) of the participants, and 342 (66%) were living with HIV. Warts were diagnosed in 252 (54%), including anal warts in 234 (43%) and penile warts in 44 (8%); 26 (5%) had both anal and penile warts. Factors independently associated with warts included HIV (AOR:2.97; CI:1.44-6.14), engaging in receptive anal sex (AOR:3.49; CI:1.25-9.75), having multiple male sexual partners (AOR:7.26; CI:2.11-24.87), age at sexual debut (AOR:0.53; CI:0.28-0.98), and non-binary gender identity (AOR:0.20; CI:0.05-0.71). Warts were common among SGM in Nigeria, particularly those living with HIV. Administration of HPV vaccination before sexual debut or as a catch-up vaccination may prevent HPV-associated complications.

Abstract
High-risk human papillomaviruses (HR HPVs) are associated with multiple human cancers and comprise 5% of the human cancer burden. Although most infections are transient, persistent infections are a major risk factor for cancer development. The life cycle of HPV is intimately linked to epithelial differentiation. HPVs establish infection at a low copy number in the proliferating basal keratinocytes of the stratified epithelium. In contrast, the productive phase of the viral life cycle is activated upon epithelial differentiation, resulting in viral genome amplification, high levels of late gene expression, and the assembly of virions that are shed from the epithelial surface. Avoiding activation of an innate immune response during the course of infection plays a key role in promoting viral persistence as well as completion of the viral life cycle in differentiating epithelial cells. This review highlights the recent advances in our understanding of how HPVs manipulate the host cell environment, often in a type-specific manner, to suppress activation of an innate immune response to establish conditions supportive of viral replication.

Abstract
Anal squamous cell carcinoma (SCC) is a human papillomavirus (HPV)-mediated malignancy with increasing incidence. HIV infection is a significant risk factor for anal SCC, however it is unknown if HIV infection alters anal lesion progression and HPV strain profile. This study aims to determine whether HIV co-infection is associated with progression of HPV-mediated anal lesions and on their HPV strain diversity. This is a retrospective cohort study of adults with anal squamous intraepithelial lesion (SIL) who presented for anorectal sampling between 2010-2019. Using the full cohort, we performed clinicopathologic epidemiologic analysis of HIV co-infection on lesion progression. Using a subset of patients, we conducted molecular analysis of HPV strain diversity as related to HIV status and progression. Our cohort included 2203 individuals, of which 940 (43%) were HIV+. HIV+ status was associated with faster progression at all levels of dysplasia. Our molecular cohort included 329 adults, of which 190 (57.8%) were HIV+. HIV+ status was associated with higher HPV strain diversity (median: 7 [5-9] vs. median: 4 [4-6], P<0.001). Latent class analysis identified specific HPV strain signatures associated with progression. We demonstrate that HIV+ individuals had faster rates of anal SIL progression and that almost all HPV strains were more prevalent in anal samples from HIV+ adults. Our results imply that HIV+ adults with anal SIL should undergo more frequent screening and obtain HPV genotyping at initial presentation, as it shows value as a biomarker of lesion progression.

Role of Epstein-Barr Virus and Human Papilloma Virus in the Development of Oropharyngeal Cancer: A Literature Review. Int J Dent 2022; 2022:3191569.

Abstract
The aim of this review was to describe the association and related mechanisms between HPV, EBV, and the development of oral and oropharyngeal cancer. A search for scientific evidence was carried out in electronic databases (MEDLINE/PubMed, SciELO). It was found that, among the carcinogenic mechanisms of HPV, E6 and E7 proteins are responsible for the malignization process, inhibiting tumor suppressors p53 and pRb. As to EBV, it was noted that its “hit and run” phenomenon manipulates the host epigenetic mechanism, triggering the tumor process without the virus being currently present; a “cellular reprogramming” is essentially generated, causing heritable changes in gene expression without DNA mutation. In conclusion, there is an association between oropharyngeal carcinogenesis and HPV and also between the former and EBV. Further studies are required to clarify the causal mechanisms and impact of both viruses on cancer development and to obtain biomarkers of greater specificity in the case of EBV.

Abstract
Background Human papillomavirus infection, a causative agent of cervical cancer, is of great concern, more so in populations with high HIV prevalence, such as South Africa. Aim This review aimed to examine the prevalence and distribution of selected cervical human papillomavirus (HPV) types in HIV infected and HIV uninfected women in South Africa. Methods PubMed and Web of Science databases were searched using key words. For data integrity, data was assessed by two authors independently. The study inclusion criteria comprised records on cervical HPV, HPV genotyping and HPV type distribution among South African women. Statistical analysis was performed using Social Science Statistics. Results Sixty-nine articles met the inclusion criteria for analysis. Data on cervical HPV prevalence and type distribution was available only for five of the nine provinces of South Africa. Only 4/69 studies used sequencing as an approach to identify HPV types. In a general population, HPV type 16 was the most frequent (8.80%), followed by types 35 (4.86%), 18 (4.14%), 58 and 52 with the frequency of 3.65% and 3.62%, respectively. Furthermore, the least frequent type was HPV 70 (0.74%). Both HIV infected and HIV uninfected populations had a higher prevalence of high-risk human papillomavirus (hrHPV) types 16, 18 and 35 than other HPV types; while HPV types 6, 11 and 70 were the least frequent types from these populations. Lastly, HPV 16 was the most predominant type among women with normal (2.03%) and abnormal cervical cytology (6.60%). Conclusion Expanding on HPV genotyping will improve the knowledge in patterns of HPV type distribution in South Africa that will further help in decision making to improve current diagnostics, and future vaccine development and assessment.

Abstract
Background and Objectives: Romania faces one of the highest cervical cancer burdens in Europe though it is a preventable cancer through population screening by cytology and human papillomavirus (HPV) detection. Also, it has one of the highest incidences of human immunodeficiency virus (HIV) infection. HPV and HIV coinfection are frequently encountered. The aim of study was to establish the prevalence of HPV infection among HIV-positive women in Southeast Region of Romania, to genotype high risk HPV types -and to correlate the results with clinical data and cytological cervical lesions. Materials and Methods: 40 HIV-positive women were screened for HPV types and for cytological cervical lesions. The findings were evaluated in correlation with CD4 cell counts, HIV viral load, age at first sexual intercourse, number of sexual partners, vaginal candidiasis, and Gardnerella using statistical methods. Results: 19/40 (47.5%) women were positive for HPV types, 63.15% infected with single HPV type and 36.85% with multiple HPV types. The most frequent types were type: 31 (42.1%), 56 (31.57%), 53 (15.78%). On cytology, 34 (85%) women were found with NILM of which 38.23% were HPV-positive. Fifteen percent of women had abnormal cytology (three ASC-US, three LSIL), and all of them were HPV-positive. Through analyzing the value of CD4 count, women with CD4 count ≤ 200 cells/μL were found to be significantly more likely to be infected with HPV; meanwhile there was no correlation between the detection of HPV types and HIV viral load. Candida or Gardnerella were more often associated with HIV-positive women with HPV, than in women without HPV. Conclusions: Infection with HPV types is common among HIV-positive women in the Southeast Region of Romania and it is associated with age at the beginning of sexual life, number of sexual partners, CD4 value, vaginal candidiasis, and Gardnerella infection.

Evidence of latent HPV infection in older Danish women with a previous history of cervical dysplasia. Acta Obstet Gynecol Scand 2022; 101:608-615. [PMID: 35481603 DOI: 10.1111/aogs.14362] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2021] [Revised: 03/27/2022] [Accepted: 03/28/2022] [Indexed: 11/27/2022]
Abstract
INTRODUCTION Understanding whether human papillomavirus (HPV) may establish latency in the uterine cervix is important. A better understanding of HPV natural history is useful for clinical counseling of women attending screening and to accurately inform health prevention strategies such as screening and HPV vaccination. We evaluated the extent of latent HPV infections in older women with a history of abnormal cytology. MATERIAL AND METHODS We conducted a cross-sectional study in Aarhus, Denmark, from March 2013 through April 2015. Women were enrolled if they underwent cervical amputation or total hysterectomy because of benign disease. Prior to surgery, women completed a questionnaire and a cervical smear was collected for HPV testing and morphological assessment. For evaluation of latency (i.e., no evidence of active HPV infection, but HPV detected in the tissue), we selected women with a history of abnormal cervical cytology or histology, as these women were considered at increased risk of harboring a latent infection. Cervical tissue underwent extensive HPV testing using the SPF10-DEIA-LipA25 assay. RESULTS Of 103 women enrolled, 26 were included in this analysis. Median age was 55 years (interquartile range [IQR] 52-65), and most women were postmenopausal and parous. The median number of sexual partners over the lifetime was six (IQR 3-10), and 85% reported no recent new sexual partner. Five women (19.2%) had evidence of active infection at the time of surgery, and 19 underwent latency evaluation. Of these, a latent infection was detected in 11 (57.9%), with HPV16 being the most prevalent type (50%). Nearly 80% (n = 14) of the 18 women with a history of previous low-grade or high-grade cytology with no treatment had an active or latent HPV infection, with latent infections predominating. HPV was detected in two of the six women with a history of high-grade cytology and subsequent excisional treatment, both as latent infections. CONCLUSIONS HPV can be detected in cervical tissue specimens without any evidence of an active HPV infection, indicative of a latent, immunologically controlled infection. Modeling studies should consider including a latent state in their model when estimating the appropriate age to stop screening and when evaluating the impact of HPV vaccination.

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.

Abstract
The aim of this article was to present a summary of the current resources available in the literature regarding the role of inflammation in anal cancer development. Anal cancer is relatively uncommon, accounting for about 2.7% of all reported gastrointestinal cancers in the United States. However, the importance of understanding the pathogenesis and risk factors for anal cancer has been recognized over the last several decades due to a noticed increase in incidence worldwide. Infections, autoimmune diseases, and inflammatory diseases of unknown etiology cause chronic inflammation that promotes tumorigenesis. The association between chronic inflammation and cancer development is widely accepted. It is based on different pathophysiological mechanisms that lead to cellular transformation and changes in immunological response, allowing tumor cells to avoid apoptosis and immune surveillance. However, there are still many molecular and cellular mechanisms that remain largely unexplored. Further studies on this topic could be of tremendous significance in elucidating anal cancer pathogenesis and developing immunotherapeutic approaches for its treatment.

Possible Reactivation of Latent Anal Human Papillomavirus Associated with Markers of Immune Dysfunction in Gay and Bisexual Men. Cancer Epidemiol Biomarkers Prev 2022; 31:1052-1057. [PMID: 35244674 DOI: 10.1158/1055-9965.epi-21-1346] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2021] [Revised: 01/16/2022] [Accepted: 02/18/2022] [Indexed: 11/16/2022] Open
Abstract
BACKGROUND It is unknown whether reactivation of human papillomavirus (HPV) after latency occurs in the anus. We measured incidence and predictors of incident anal HPV in sexually inactive gay and bisexual men (GBM) as a surrogate of HPV reactivation. METHODS The Study of the Prevention of Anal Cancer collected data on sexual behavior, anal cytology, HPV DNA, histology and HPV serology. HPV incidence during periods when zero sexual partners were reported in the last six months at both the current and previous annual visit ("no sexual activity") was analyzed by Cox regression using the Wei-Lin-Weissfeld method to determine univariable predictors. RESULTS Of 617 men enrolled, 525 had results for ≥2 visits, of whom 58 (11%) had ≥ one period of "no sexual activity". During sexually inactive periods, there were 29 incident high risk HPV infections in 20 men, which occurred more commonly in older men (Ptrend = 0.010), HIV-positive men (HR = 3.12; 95% CI, 0.91-16.65), longer duration of HIV (Ptrend = 0.028), history of AIDS defining illness (P = 0.010), lower current (P = 0.010) and nadir CD4 count (P = 0.014). For 18 of 29 infections with available results, 12 men remained type-specific HRHPV L1 seronegative. None were consistently seropositive. A new diagnosis of HSIL occurred in only two men, caused by an HPV type other than the incident type. CONCLUSIONS Our findings suggest that in sexually inactive GBM, anal HRHPV incidence is relatively common, and is associated with increasing age and immune dysfunction, a pattern consistent with HPV reactivation. IMPACT Reactivation of anal HPV may occur.

Abstract
Human papillomavirus (HPV) and human immunodeficiency virus (HIV) infections are sexually transmitted. There are several HPV genotypes and clinical manifestations. Determining which genotypes circulate worldwide and/or in specific geographic areas can help with prevention programs and vaccine distribution. This systematic review aimed to investigate the most frequent anal and cervical HPV genotypes in women co-infected with HPV/HIV. The PubMed, Scientific Electronic Library Online, and Latin American and Caribbean Literature in Health Sciences databases were used to search for articles published between January 2015 and August 2021, and the included articles followed the defined selection criteria. Based on the 51 articles included, HPV16 was the most prevalent (41%) genotype, followed by HPV52 (17%) and HPV58 (14%). Based on the comparative analyses of the HIV-negative women with HPV and the HPV/HIV co-infected groups, HPV16 was frequent in both groups; HPV58, HPV31, and HPV52 were more frequent in the co-infected group; and HPV18 was more common in HIV-negative women with HPV. HPV/HIV co-infected women most frequently presented the HPV genotypes 16, 58, and 52, whereas HIV-negative women with HPV had a higher frequency of HPV16, HPV18, and HPV52 genotypes. The results indicate the importance of genotype surveillance as a strategy to improve preventive measures against HPV infection and its complications.

Abstract
Background Viral infections are emerging with diverse clinical relevance both in endemic environments and non-endemic regions of the world. Some of the viruses cause co-infections that are of public health importance. The progress of studies on human immunodeficiency virus / Human papillomavirus (HIV/HPV) co-infection is not well documented especially in Africa where cases are endemic. Method Using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we conducted a global three-decade meta-synthesis and science mapping analysis on HIV/HPV co-infections. Assessment of progress, Author/Country productivity/trends, topic conceptual framework, and international collaborative networks were analyzed. Results We recovered 196 documents of 115 sources from the web of science database. The meta-synthesis revealed 1203 prolific authors containing nine solo authors, an annual growth rate of 8.09%, a significant average citation per article of 20.7%, and an average citation per year per document of 2.1. A significant high correlation between the mean/TC per article and the mean total citation (TC) per year showed 80.98% of the articles produced between 2005 and 2007 on HPV/HIV co-infection. The co-author per document index were 7.0 and the collaboration index was 6.4. The meta-analysis also revealed inadequate funding from individual or governmental organizations; among the 196 documents dataset, 114 (58.2%) were funded, and only 31 (15.8%) were funded in Africa where HIV/HPV co-infection cases are endemic. Conclusions Authors’ collaboration network, countries’ collaboration, authors’ citations and implementation of research-based finding in previous studies are yet to receive the relevant outcome, especially as various countries in the African continent have received poor funding with a repeated reporting of co-infection associated with HIV/HPV. African needs to re-awaken and stir up research-based interest in HPV/HIV co-infection studies to resolve indigenous public health concerns associated with the viral endemicity.

Abstract
The risk of HIV acquisition is low on a per-contact basis but increased by transmission co-factors such as other sexually transmitted infections (STIs). Human papillomavirus (HPV) is a prevalent STI that most individuals will acquire HPV in their lifetime. Current HPV vaccines can prevent newly acquired infections, but are largely ineffective against established HPV, complicating worldwide eradication efforts. In addition to being the causative agent of cervical cancer, accumulating evidence suggests that HPV infection and/or accompanying cervical inflammation increase the risk of HIV infection in men and women. The fact that immunological features observed during HPV infection overlap with cellular and molecular pathways known to enhance HIV susceptibility underscore the potential interplay between these two viral infections that fuel their mutual spread. Here we review current insights into how HPV infection and the generation of anti-HPV immunity contribute to higher HIV transmission rates, and the impact of HPV on mucosal inflammation, immune cell trafficking, and epithelial barrier function.

Cervical Cancer Prevention and High-Risk HPV Self-Sampling Awareness and Acceptability among Women Living with HIV: A Qualitative Investigation from the Patients’ and Providers’ Perspectives. Curr Oncol 2022; 29:516-533. [PMID: 35200547 PMCID: PMC8870184 DOI: 10.3390/curroncol29020047] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2021] [Revised: 01/14/2022] [Accepted: 01/21/2022] [Indexed: 02/07/2023] Open
Abstract
Routine cervical cancer screening is important for women living with HIV (WLH) due to the greater incidence and persistence of high-risk HPV (HR-HPV) infection. HR-HPV self-sampling has been proposed to overcome barriers to in-office cervical cancer screening in underserved populations. However, little is known about baseline knowledge of HR-HPV and the acceptability of HR-HPV self-sampling among WLH. This paper describes WLH’s experiences and needs regarding cervical cancer screening, specifically HR-HPV self-sampling, and seeks to reconcile their experiences with the views of their providers. In total, 10 providers and 39 WLH participated in semi-structured interviews and group discussions, respectively. Knowledge of cervical cancer and HR-HPV was generally limited among WLH; when present, it was often due to personal experience of or proximity to someone affected by cervical cancer. Most WLH were not familiar with HR-HPV self-sampling but, despite some of the providers’ skepticism, expressed their willingness to participate in a mail-based HR-HPV self-sampling intervention and highlighted convenience, ease of use, and affordability as facilitators to the uptake of HR-HPV self-sampling. The experiences identified can be used to guide patient-centered communication aimed at improving cervical cancer knowledge and to inform interventions, such as HR-HPV self-sampling, designed to increase cervical cancer screening among under-screened WLH.

Abstract
Objective Vaccine efficacy among previously exposed, but currently uninfected women, i.e., those who have serological evidence of a prior human papillomavirus (HPV) infection without corresponding detectable HPV DNA, remains incompletely defined. This meta-analysis assessed the serotype-specific efficacy of prophylactic HPV vaccination against HPV16/18 persistent infection (PI) and cervical intraepithelial neoplasia (CIN) among seropositive, DNA negative (SPDN) women enrolled to randomized controlled trials (RCTs) of HPV L1-based vaccines. Methods Searches were conducted on 08/16/20 on MEDLINE, Embase, Scopus and CENTRAL. RCTs of L1-based prophylactic bivalent or quadrivalent HPV vaccines, reporting serotype-specific clinical efficacy endpoints in the HPV16/18 seropositive, DNA-negative populations were included. Relative risks (RRs) of 6-month PI (6mPI), 12-month PI (12mPI), CIN1+ and CIN2+ were pooled using a random-effects model. Results A total of 1,727 citations were reviewed. 8 studies, with a total of 9,569 SPDN participants, met all eligibility criteria. The RR of 6mPI (RR=0.22; 95% confidence interval [CI]=0.08–0.61; p=0.018), 12mPI (RR=0.20; 95% CI=0.05–0.80; p=0.035), CIN1+ (RR=0.13; 95% CI=0.05–0.30; p=0.003) and CIN2+ (RR=0.15; 95% CI=0.04–0.59; p=0.022) was significantly reduced in the vaccinated compared to the unvaccinated group. Conclusion Our findings suggest high serotype-specific efficacy for HPV vaccination among cohorts of women with evidence of prior HPV16/18 infections, including 87% efficacy (95% CI=70%–95%; p=0.003) against HPV16/18 cervical dysplasia. HPV vaccination is highly effective among uninfected women, regardless of prior exposure history. Trial Registration PROSPERO Identifier: CRD42020206888

Abstract
Malignancies constitute the second cause of death in patients with inflammatory bowel diseases (IBD), after cardiovascular diseases. Although it has been postulated that IBD patients are at greater risk of colorectal cancer compared to the general population, lately there has been evidence supporting that this risk is diminishing over time as a result of better surveillance, while the incidence of extraintestinal cancers (EICs) is increasing. This could be attributed either to systemic inflammation caused by IBD or to long-lasting immunosuppression due to IBD treatments. It seems that the overall risk of EICs is higher for Crohn’s disease patients and it is mainly driven by skin cancers, and liver-biliary cancers in patients with IBD and primary sclerosing cholangitis. The aims of this review were first to evaluate the prevalence, characteristics, and risk factors of EICs in patients with IBD and second to raise awareness regarding a proper surveillance program resulting in early diagnosis, better prognosis and survival, especially in the era of new IBD treatments that are on the way.

Abstract
BackgroundWomen living with HIV in sub-Saharan Africa are at increased risk to develop cervical cancer (CC), which is caused by persistent infection with 13 oncogenic human papilloma viruses (HR-HPVs). It is important to accurately identify and target HIV-positive women at highest risk to develop CC for early therapeutic intervention.MethodsA total of 2,134 HIV+ and HIV− women from South-West Tanzania were prospectively screened for cervical cancer and precancerous lesions. Women with cervical cancer (n=236), high- and low-grade squamous intraepithelial lesions (HSIL: n=68, LSIL: n=74), and without lesion (n=426) underwent high-resolution HPV genotyping.ResultsEighty percent of women who were diagnosed with HSIL or LSIL were living with HIV. Any lesion, young age, HIV status, and depleted CD4 T cell counts were independent risk factors for HPV infections, which were predominantly caused by HR-HPV types. While multiple HR-HPV type infections were predominant in HIV+ women with HSIL, single-type infections predominated in HIV+ CC cases (p=0.0006). HPV16, 18, and 45 accounted for 85% (68/80) and 75% (82/110) of HIV+ and HIV− CC cases, respectively. Of note, HPV35, the most frequent HPV type in HSIL-positive women living with HIV, was rarely detected as a single-type infection in HSIL and cancer cases.ConclusionHPV16, 18, and 45 should receive special attention for molecular diagnostic algorithms during CC prevention programs for HIV+ women from sub-Saharan Africa. HPV35 may have a high potential to induce HSIL in women living with HIV, but less potential to cause cervical cancer in single-type infections.

Abstract
Background Cervical cancer - caused by persistent High Risk Human Papilloma Virus (HR HPV) infections - is the second most common cancer affecting women globally. HIV infection increases the risk for HPV persistence, associated disease progression and malignant cell transformation. We therefore hypothesized that this risk increase is directly linked to HIV infection associated dysfunction or depletion of HPV-oncoprotein-specific T-cell responses. Methods The 2H study specifically included HIV+ and HIV- women with and without cervical lesions and cancer to analyze HPV oncogene-specific T cell responses in relation to HPV infection, cervical lesion status and HIV status. Oncoprotein E6 and E7 specific T-cell responses were quantified for the most relevant types HPV16, 18 and 45 and control antigens (CMV-pp65) and M.tb-PPD in 373 women, using fresh peripheral blood mononuclear cells in an IFN-γ release ELISpot assay. Results Overall, systemic E6- and E7-oncoprotein-specific T-cell responses were infrequent and of low magnitude, when compared to CMV-pp65 and M.tb-PPD (p < 0.001 for all HR HPV types). Within HIV negative women infected with either HPV16, 18 or 45, HPV16 infected women had lowest frequency of autologous-type-E6/E7-specific T-cell responses (33%, 16/49), as compared to HPV18 (46% (6/13), p = 0.516) and HPV45 (69% (9/13), p = 0.026) infected women. Prevalent HPV18 and 45, but not HPV16 infections were linked to detectable oncoprotein-specific T-cell responses, and for these infections, HIV infection significantly diminished T-cell responses targeting the autologous infecting genotype. Within women living with HIV, low CD4 T-cell counts, detectable HIV viremia as well as cancerous and precancerous lesions were significantly associated with depletion of HPV oncoprotein-specific T-cell responses. Discussion Depletion of HPV-oncoprotein-specific T-cell responses likely contributes to the increased risk for HR HPV persistence and associated cancerogenesis in women living with HIV. The low inherent immunogenicity of HPV16 oncoproteins may contribute to the exceptional potential for cancerogenesis associated with HPV16 infections.

Abstract
Despite being highly preventable, cervical cancer is the fourth most common cancer and cause of cancer death in women globally. In low-income countries, cervical cancer is often the leading cause of cancer-related morbidity and mortality. Women living with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome are at a particularly high risk of cervical cancer because of an impaired immune response to human papillomavirus, the obligate cause of virtually all cervical cancers. Globally, approximately 1 in 20 cervical cancers is attributable to HIV; in sub-Saharan Africa, approximately 1 in 5 cervical cancers is due to HIV. Here, the authors provide a critical appraisal of the evidence to date on the impact of HIV disease on cervical cancer risk, describe key methodologic issues, and frame the key outstanding research questions, especially as they apply to ongoing global efforts for prevention and control of cervical cancer. Expanded efforts to integrate HIV care with cervical cancer prevention and control, and vice versa, could assist the global effort to eliminate cervical cancer as a public health problem.

[PMID: 34576278 PMCID: PMC8472041 DOI: 10.3390/ijms221810115] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2021] [Revised: 09/04/2021] [Accepted: 09/06/2021] [Indexed: 11/16/2022] Open
Abstract
Cervical cancer is a public health problem and has devastating effects in low-to-middle-income countries (LTMICs) such as the sub-Saharan African (SSA) countries. Infection by the human papillomavirus (HPV) is the main cause of cervical cancer. HIV positive women have higher HPV prevalence and cervical cancer incidence than their HIV negative counterparts do. Concurrent HPV/HIV infection is catastrophic, particularly to African women due to the high prevalence of HIV infections. Although various studies show a relationship between HPV, HIV and cervical cancer, there is still a gap in the knowledge concerning the precise nature of this tripartite association. Firstly, most studies show the relationship between HPV and cervical cancer at genomic and epigenetic levels, while the transcriptomic landscape of this relationship remains to be elucidated. Even though many studies have shown HPV/HIV dual viral pathogenesis, the dual molecular oncoviral effects on the development of cervical cancer remains largely uncertain. Furthermore, the effect of highly active antiretroviral therapy (HAART) on the cellular splicing machinery is unclear. Emerging evidence indicates the vital role played by host splicing events in both HPV and HIV infection in the development and progression to cervical cancer. Therefore, decoding the transcriptome landscape of this tripartite relationship holds promising therapeutic potential. This review will focus on the link between cellular splicing machinery, HPV, HIV infection and the aberrant alternative splicing events that take place in HIV/HPV-associated cervical cancer. Finally, we will investigate how these aberrant splicing events can be targeted for the development of new therapeutic strategies against HPV/HIV-associated cervical cancer.

Human Immunodeficiency Virus Infection Promotes Human Papillomavirus-Mediated Anal Squamous Carcinogenesis: An Immunologic and Pathobiologic Review. Pathobiology 2021; 89:1-12. [PMID: 34535611 DOI: 10.1159/000518758] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2021] [Accepted: 07/28/2021] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND Anal squamous cell carcinoma (SCC) is a rare gastrointestinal malignancy with rising incidence, both in the United States and internationally. The primary risk factor for anal SCC is human papillomavirus (HPV) infection. However, there is a growing burden of disease in patients with human immunodeficiency virus (HIV) and HPV coinfection, with the incidence of anal SCC significantly increasing in this population. This is particularly true in HIV-infected men. The epidemiologic correlation between HIV-HPV coinfection and anal SCC is established; however, the immunologic mechanisms underlying this relationship are not well understood. SUMMARY HIV-related immunosuppression due to low circulating CD4+ T cells is one component of increased risk, but other mechanisms, such as the effect of HIV on CD8+ T lymphocyte tumor infiltration and the PD-1/PD-L1 axis in antitumor and antiviral response, is emerging as significant contributors. The goal of this article is to review existing research on HIV-HPV coinfected anal SCC and precancerous lesions, propose explanations for the detrimental synergy of HIV and HPV on the pathogenesis and immunologic response to HPV-associated cancers, and discuss implications for future treatments and immunotherapies in HIV-positive patients with HPV-mediated anal SCC. Key Messages: The incidence of anal squamous cell carcinoma is increased in human immunodeficiency virus (HIV)-infected patients, even in patients on highly active antiretroviral therapy. Locoregional HIV infection may enhance human papillomavirus oncogenicity. Chronic inflammation due to HIV infection may contribute to CD8+ T lymphocyte exhaustion by upregulating PD-1 expression, thereby blunting cytotoxic antitumor response.

Abstract
Introduction cervical intraepithelial neoplasia the precursor of cervical cancer occurs with increased frequency in women infected with human immunodeficiency virus (HIV). This study aimed at determining the prevalence and correlates of abnormal cervical cytology among HIV-infected women and compare to the uninfected women. Methods a cross-sectional study conducted among HIV-infected and uninfected women enrolled in a HIV study in Central Kenya. All women had baseline Pap smear examination assessed using Bethesda system. Bivariate and multivariate logistic regression methods were employed to assess the correlates of cervical squamous epithelial lesions (CSIL). Results a total 480 women had an acceptable baseline smear, 373 (78%) were HIV-infected. Median age was 30.2 years [IQR 25.4-35.5]. Overall prevalence of CSIL was 37% (176/480) with the prevalence of low grade squamous intraepithelial lesion (LSIL), atypical squamous cells undetermined significance (ASCUS), high grade squamous intraepithelial lesions (HSIL) and atypical glandular cells (AGC) were 17%, 14%, 4% and 2% respectively. HIV-infected women had a higher prevalence of CSIL at 42% as compared to HIV-uninfected women at 19%. HIV infection was the predictor associated with development of CSIL at multivariate analysis and specifically, HIV-infected women were 3 times (AOR 3.1, 95% CI: 1.8 - 5.4, p<0.005) more likely to have CSIL than HIV-uninfected women. The age 35 - 44 years was protective to developing CSIL (AOR 0.45, 95% CI: 0.24 - 0.87, p=0.018). Conclusion cervical squamous epithelial lesions is a major problem among Kenyan women. HIV infection confers a higher risk to development of CSIL. Cervical cancer screening should be an established practice in HIV programs.

Abstract
In 2019, the National Institutes of Health combined the Multicenter AIDS Cohort Study (MACS) and the Women's Interagency HIV Study (WIHS) into the MACS/WIHS Combined Cohort Study (MWCCS). In this paper, participants who made a study visit during October 2018-September 2019 (targeted for MWCCS enrollment) are described by human immunodeficiency virus (HIV) serostatus and compared with people living with HIV (PLWH) in the United States. Participants include 2,115 women and 1,901 men with a median age of 56 years (interquartile range, 48-63); 62% are PLWH. Study sites encompass the South (18%), the Mid-Atlantic/Northeast (45%), the West Coast (22%), and the Midwest (15%). Participant race/ethnicity approximates that of PLWH throughout the United States. Longitudinal data and specimens collected for 35 years (men) and 25 years (women) were combined. Differences in data collection and coding were reviewed, and key risk factor and comorbidity data were harmonized. For example, recent use of alcohol (62%) and tobacco (28%) are common, as are dyslipidemia (64%), hypertension (56%), obesity (42%), mildly or severely impaired daily activities (31%), depressive symptoms (28%), and diabetes (22%). The MWCCS repository includes serum, plasma, peripheral blood mononuclear cells, cell pellets, urine, cervicovaginal lavage samples, oral samples, B-cell lines, stool, and semen specimens. Demographic differences between the MACS and WIHS can confound analyses by sex. The merged MWCCS is both an ongoing observational cohort study and a valuable resource for harmonized longitudinal data and specimens for HIV-related research.

Abstract
BACKGROUND The causative role of human papillomavirus (HPV) in cervical carcinogenesis is well established; however, prospective studies examining high-risk(HR)-HPV acquisition among adult women in HIV-prevalent settings are limited. METHODS We conducted a prospective study among women (25-60 years) attending cervical cancer screening in Tanzania. Cervical specimens obtained at enrolment and follow-up were tested for HPV. Participants were interviewed on lifestyle and tested for HIV. RESULTS Among 3805 eligible women, 3074 (80.8%) attended follow-up (median time between the 2 examinations, 17.3 months); 307 had missing HPV results at enrolment or follow-up, leaving 2767 study participants. Among 2253 women initially HR-HPV negative, 184 acquired HR-HPV-incidence: 54.5 per 1000 person-years (95% CI:47.1-62.9); among HIV-positive women 75.2 per 1000 person-years (95% CI:54.5-103.7), HIV-negative 50.9 per 1000 person-years (95% CI:43.3-60.0). HPV52 and HPV16 were the most frequently acquired types. In multivariable regression analysis, HIV positivity, low CD4 count, younger age, and multiple sexual partners were associated with increased odds of HPV acquisition. CONCLUSION HPV acquisition was higher among HIV-positive than HIV-negative women, especially women with low CD4 counts. Improvement of immune status among HIV-positives may decrease HPV acquisition. Nonavalent HPV vaccination should be considered given the pattern of HR-HPV types acquired.

Abstract
BACKGROUND Although female sex workers (FSWs) have long been identified as a key human papillomavirus (HPV)-affected population, the burden and scope of their disproportionate risk for HPV infection have not been systematically estimated. We therefore aimed to estimate the prevalence of HPV and the distribution of HPV types in FSWs at the country, regional and global levels. METHODS We searched the PubMed, Embase, SCOPUS, EBSCO, ProQuest, Cochrane Library and Web of Science databases for articles published between 1 January 1990 and 31 June 2019. Studies of genital HPV prevalence in FSWs, or with sufficient data (e.g. adequate number of HPV-positive cases and sample size) to compute prevalence rates in FSWs, were included in this systematic review. The meta-analysis was completed using the random effects model. RESULTS We ultimately identified 107 studies in 45 countries or regions with sufficient data to calculate HPV prevalence in FSWs. The pooled global HPV prevalence among FSWs was 39.5% (95% CI 35.3, 43.9%), with notable variations by WHO region and country. Globally, the five most common HPV types in FSWs were HPV16 (9.0%), HPV 52 (8.3%), HPV89 (7.0%), HPV58 (6.2%), and HPV53 (5.3%). CONCLUSIONS Our findings suggest that FSWs are disproportionately affected by HPV, which is more pronounced in the Western Pacific and African regions, and are therefore in need of prevention, treatment and care services.

A Framework for Cervical Cancer Elimination in Low-and-Middle-Income Countries: A Scoping Review and Roadmap for Interventions and Research Priorities. Front Public Health 2021; 9:670032.

Abstract
The World Health Organization announced an ambitious call for cervical cancer elimination worldwide. With existing prevention and treatment modalities, cervical cancer elimination is now within reach for high-income countries. Despite limited financing and capacity constraints in low-and-middle-income countries (LMICs), prevention and control efforts can be supported through integrated services and new technologies. We conducted this scoping review to outline a roadmap toward cervical cancer elimination in LMICs and highlight evidence-based interventions and research priorities to accelerate cervical cancer elimination. We reviewed and synthesized literature from 2010 to 2020 on primary and secondary cervical cancer prevention strategies. In addition, we conducted expert interviews with gynecologic and infectious disease providers, researchers, and LMIC health officials. Using these data, we developed a logic model to summarize the current state of science and identified evidence gaps and priority research questions for each prevention strategy. The logic model for cervical cancer elimination maps the needs for improved collaboration between policy makers, production and supply, healthcare systems, providers, health workers, and communities. The model articulates responsibilities for stakeholders and visualizes processes to increase access to and coverage of prevention methods. We discuss the challenges of contextual factors and highlight innovation needs. Effective prevention methods include HPV vaccination, screening using visual inspection and HPV testing, and thermocoagulation. However, vaccine coverage remains low in LMICs. New strategies, including single-dose vaccination could enhance impact. Loss to follow-up and treatment delays could be addressed by improved same-day screen-and-treat technologies. We provide a practical framework to guide cervical cancer elimination in LMICs. The scoping review highlights existing and innovative strategies, unmet needs, and collaborations required to achieve elimination across implementation contexts.

Abstract
BACKGROUND Human papillomavirus (HPV)-associated cervical cancer is a leading cause of death among Indian women. Indian women living with HIV (WLWH) may be at especially high risk. The quadrivalent HPV (qHPV) vaccine is effective in prevention of initial infection with HPV-6/11/16/18 in HIV-negative women. Little is known about previous exposure to HPV-6/11/16/18, safety, and immunogenicity of qHPV in Indian WLWH. METHODOLOGY One hundred fifty WLWH with different CD4 levels and HIV viral load (VL) were vaccinated at 0/2/6 months at CART-CRS-IDMC, Chennai, India. Serology was performed at weeks 0, 28, and 52 for HPV-6/11/16/18 using a competitive Luminex immunoassay and for HPV-16/18 using a pseudovirion-based neutralization assay. RESULTS Mean age was 30.8 years (range, 19-44 years). 71/87/73/81% of women were naive (sero-negative and DNA-negative) to HPV-6/11/16/18 at baseline, respectively. Among per-protocol women naive to HPV-6/11/16/18 at baseline, 100/99/99/90%, respectively, seroconverted at week 28 and 95/96/98/71% were sero-positive at week 52, respectively. Pseudovirion-based neutralization assay identified more seroconversion to HPV-18 than competitive Luminex immunoassay. There were no significant differences in the proportion seroconverting by baseline or nadir CD4 or HIV VL; however, there was a trend for increased proportion seroconverting to HPV-18 among women with higher baseline CD4 level (P = 0.052). There were no qHPV-related serious adverse events and no change in CD4 level or HIV VL among women on ART. CONCLUSIONS qHPV vaccine was safe and immunogenic in Indian WLWH. A high proportion were naive to HPV-6/11/16/18 and may benefit from vaccination although many were married and several years post-initiation of sexual activity.

Importance of Lifetime Sexual History on the Prevalence of Genital Human Papillomavirus (HPV) Among Unvaccinated Adults in the National Health and Nutrition Examination Surveys: Implications for Adult HPV Vaccination. Clin Infect Dis 2021; 72:e272-e279. [PMID: 32710745 DOI: 10.1093/cid/ciaa1050] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2020] [Indexed: 11/12/2022] Open
Abstract
BACKGROUND Although the United States Food and Drug Administration recently approved the human papillomavirus (HPV) vaccine for individuals aged 27-45 years, the Centers for Disease Control and Prevention did not change its guidelines for routine HPV vaccination. Since recommendations for adult vaccination emphasize shared clinical decision-making based on risk of new infections, we examined the relationship between HPV prevalence and sexual behavior. METHODS This study was conducted among 5093 HPV-unvaccinated, sexually experienced adults aged 18-59 years in the National Health and Nutrition Examination Surveys (2013-2016). For each sex and age group, adjusted prevalences of 9-valent vaccine-specific, high-risk, and any HPV infection were estimated by number of lifetime sexual partners (LTSPs) using logistic regression. An analysis restricted to persons who did not have a new sexual partner in the past year (ie, removing those at highest risk of newly acquired HPV) was also conducted. RESULTS In each age group, genital HPV prevalence was higher among persons with >5 LTSPs compared with 1-5 LTSPs in both males and females. There were only slight reductions in HPV prevalence after removing participants who reported a new sexual partner in the past year. For example, among females aged 27-45 years with >5 LTSPs, the adjusted prevalence of 9-valent vaccine-type HPV infection was 13.4% (95% confidence interval [CI], 9.9%-17.0%) in the full population compared to 12.1% (95% CI, 8.8%-15.4%) among those with no new sexual partners. CONCLUSIONS Prevalent HPV infection was primarily reflective of cumulative exposures over time (higher LTSPs). New exposures had limited impact, emphasizing the need to consider sexual history in the decision-making process for adult HPV vaccination.

Veteran Women Living With Human Immunodeficiency Virus Have Increased Risk of Human Papillomavirus (HPV)-Associated Genital Tract Cancers. Clin Infect Dis 2021; 72:e359-e366. [PMID: 32785700 DOI: 10.1093/cid/ciaa1162] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2020] [Indexed: 01/03/2023] Open
Abstract
BACKGROUND Disparities in access to screening often confound observed differences in human papillomavirus (HPV)-associated female genital tract cancer (FGTC) incidence between women living with human immunodeficiency virus (HIV; WLWH) and their HIV-negative counterparts. We aimed to determine if there have been changes in cancer risk among WLWH during the antiretroviral era in a single-payer health system. METHODS We retrospectively selected WLWH and HIV-negative controls receiving care between 1999 and 2016 at the US Department of Veterans Affairs (VA) and identified FGTC diagnoses via Cancer Registry and International Classification of Diseases-9/10 codes. We extracted demographic and clinical variables from the VA's Corporate Data Warehouse; evaluated incidence rates (IRs), incidence rate ratios, hazard ratios, and 95% confidence intervals (CIs) for cancer risk; and conducted survival analyses. RESULTS We identified 1454 WLWH and compared them with 5816 matched HIV-negative controls. More WLWH developed HPV-associated FGTCs (total n = 28 [2.0%]; cervical = 22, vulvovaginal = 4, and anal/rectal = 2) than HIV-negative women (total n = 32 [0.6%]; cervical = 24, vulvovaginal = 5, and anal/rectal = 5) (log rank P < .0001). Cervical cancer IR was >6-fold higher for WLWH (204.2 per 100 000 person-years [py] [95% CI, 83.8-324.7]) than HIV-negative women (IR = 31.2 per 100 000 py [95% CI, 17.9-44.5]). The IRs for vulvovaginal and anal cancers were also higher in WLWH. Overall, WLWH were more likely to develop HPV-associated FGTCs compared with their HIV-negative counterparts (all log rank P values < .0001). CONCLUSIONS Veteran WLWH are more likely to develop HPV-associated FGTCs despite equal access to health care. Even in single-payer health systems, WLWH continue to require special attention to ensure guideline-based high-risk HPV screening for prevention of FGTCs.

Type-specific incidence, persistence and factors associated with human papillomavirus infection among female sex workers in Benin and Mali, West Africa. Int J Infect Dis 2021; 106:348-357. [PMID: 33848674 DOI: 10.1016/j.ijid.2021.04.008] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2020] [Revised: 03/31/2021] [Accepted: 04/04/2021] [Indexed: 01/08/2023] Open
Abstract
OBJECTIVES This study in female sex workers (FSWs) aimed to: (1) estimate type-specific incidence and persistence of human papillomavirus (HPV) infection in Cotonou (Benin) and Bamako (Mali); and (2) identify the factors associated with type-specific incidence and persistence of high-risk HPV (HR-HPV) infection. METHODS A 1-year prospective cohort study on cervical cancer screening, and HPV and human immunodeficiency virus (HIV) infections was conducted among FSWs in Cotonou and Bamako from 2017 to 2019. Poisson regression models assessed factors associated with the incidence of HR-HPV infection, while log-binomial regression was performed to identify factors associated with the persistence of HR-HPV infection. Adjusted relative risks (ARR) and 95% confidence intervals (95% CI) were estimated. RESULTS The incidence of HR-HPV infection was 46.98 per 1000 women-months (predominant types HPV16, HPV35 and HPV59). Factors associated with the incidence of HR-HPV infection were age <20 years (ARR 15.10; 95% CI 3.29-69.19), age at sexual debut <18 years (ARR 6.92; 95% CI 1.97-24.27) and sex work duration ≤1 year (ARR 7.40; 95% CI 1.84-29.69). The persistence of HR-HPV infection at 12 months was 38.7% (most persistent types HPV59, HPV52 and HPV51). Persistence of HR-HPV infection was higher in women with chlamydia (P = 0.031), HIV infection (P < 0.001) and multiple-type HPV infections (P < 0.001). CONCLUSION FSWs in West Africa are at high risk of incident and persistent HR-HPV infection, suggesting an urgent need for cervical cancer screening in this population.

J Obstet Gynaecol Res 2021; 47:2185-2195. [PMID: 33754434 DOI: 10.1111/jog.14754] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2020] [Revised: 01/29/2021] [Accepted: 03/05/2021] [Indexed: 11/29/2022]
Abstract
AIM Next-generation sequencing (NGS) is able to describe the composition of human papillomaviruses (HPVs) as percent (%) reads rather than positive/negative results. Therefore, we used this unique approach to assess the prevalence of cervical HPVs of HIV infected (HIV+) in order to understand the determinants of being infected with higher % reads of high risk (HR)-HPVs and cervical abnormalities of atypical squamous cells of unknown significance or higher (ASCUS+). METHODS Study included 66 women characterized for relevant risk factors/cytology. Receiver-operating curve curve was used to derive the optimal % read cut point to identify ASCUS+ in relation to any HR-HPV genotype or other specific HPV genotypes. The determinants of ASCUS+ and HR-HPVs were tested using logistic regression. RESULTS Women with >20% reads of any HR-HPV or >12% any HR-HPV other than HPV 16/18 were 5.7 and 12.6 times more likely to be diagnosed with ASCUS+, respectively. Lower CD4 count was a significant determinant of >20% reads of HR-HPV (odds ratio [OR] = 4.1) or >12% any HR-HPV other than HPV 16/18 (OR = 4.5). CONCLUSION We envision that the NGS-based HPV detection will be more accurate for screening and management of HIV+ at risk for developing cervical cancer (CC). We raise concerns regarding the limitations of 16/18-based HPV testing for triage and the efficacy of current HPV vaccines for preventing CC in HIV+.

A proposed new generation of evidence-based microsimulation models to inform global control of cervical cancer. Prev Med 2021; 144:106438.

Abstract
Health decision models are the only available tools designed to consider the lifetime natural history of human papillomavirus (HPV) infection and pathogenesis of cervical cancer, and the estimated long-term impact of preventive interventions. Yet health decision modeling results are often considered a lesser form of scientific evidence due to the inherent needs to rely on imperfect data and make numerous assumptions and extrapolations regarding complex processes. We propose a new health decision modeling framework that de-emphasizes cytologic-colposcopic-histologic diagnoses due to their subjectivity and lack of reproducibility, relying instead on HPV type and duration of infection as the major determinants of subsequent transition probabilities. We posit that the new model health states (normal, carcinogenic HPV infection, precancer, cancer) and corollary transitions are universal, but that the probabilities of transitioning between states may vary by population. Evidence for this variability in host response to HPV infections can be inferred from HPV prevalence patterns in different regions across the lifespan, and might be linked to different average population levels of immunologic control of HPV infections. By prioritizing direct estimation of model transition probabilities from longitudinal data (and limiting reliance on model-fitting techniques that may propagate error when applied to multiple transitions), we aim to reduce the number of assumptions for greater transparency and reliability. We propose this new microsimulation model for critique and discussion, hoping to contribute to models that maximally inform efficient strategies towards global cervical cancer elimination.

Abstract
BACKGROUND Persistent infection with high-risk human papillomavirus (hrHPV) is a critical step in cervical carcinogenesis. We report on type-specific hrHPV persistence, clearance and incidence among screen-positive Rwandan women living with HIV (WLWH). METHODS This was a nested analysis from a large cervical cancer screening study of ~ 5000 Rwandan WLWH. Women who tested positive for hrHPV and/or visual inspection with acetic acid were referred to colposcopy. For a subset of women (n = 298) who were ≥ 6 months delayed in receiving colposcopy, we tested their screening and colposcopy visit specimens using the AmpFire HPV genotyping assay that tests 14 hrHPV types (16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, and 68) individually. RESULTS The mean, median (interquartile range [IQR]) and range of time between the screening and colposcopy visits were 644, 650 (490-820.5) and 197-1161 days, respectively. Mean, median (IQR) and range of age at the screening visit were 38, 37 (34-43) and 30-54 years, respectively. Two-hundred eighty-three (95.0%) had CD4 count (cells per mm3) data available at baseline with mean, median (IQR) and range of 592, 513 (346-717) and 0-7290, respectively. Two-hundred thirty-five WLWH were positive for at least one hrHPV type at the screening visit, of whom 50.2% had at least one HPV type-specific infection persist; 37.2% of all HPV infections detected at the screening visit persisted. Compared to all other HPV types in aggregate, HPV16 (vs. non-HPV16 types) (47.7%, p = 0.03) and HPV33 (vs. non-HPV33 types) (56.7%, p = 0.03) were significantly more likely, and HPV39 (vs. non-HPV39 types) (6.7%, p = 0.01), HPV51 (vs. non-HPV51 types) (15.6%, p < 0.01), and HPV66 (vs. non-HPV66 types (17.9%, p = 0.04) were significantly less likely, to persist. Lower CD4 counts were associated with having any persistent hrHPV infection (ptrend = 0.04) and multiple persistent hrHPV infections (ptrend = 0.04). CONCLUSION There is a significant proportion of WLWH with persistent hrHPV infection, emphasizing the need to vaccinate them against HPV prior to becoming sexually active.

Abstract
People living with human immunodeficiency virus (HIV-1) are at increased risk of developing cancer, such as Kaposi sarcoma (KS), non-Hodgkin lymphoma (NHL), cervical cancer, and other cancers associated with chronic viral infections. Traditionally, this is linked to HIV-1-induced immune suppression with depletion of CD4+ T-helper cells, exhaustion of lymphopoiesis and lymphocyte dysfunction. However, the long-term successful implementation of antiretroviral therapy (ART) with an early start did not preclude the oncological complications, implying that HIV-1 and its antigens are directly involved in carcinogenesis and may exert their effects on the background of restored immune system even when present at extremely low levels. Experimental data indicate that HIV-1 virions and single viral antigens can enter a wide variety of cells, including epithelial. This review is focused on the effects of five viral proteins: envelope protein gp120, accessory protein negative factor Nef, matrix protein p17, transactivator of transcription Tat and reverse transcriptase RT. Gp120, Nef, p17, Tat, and RT cause oxidative stress, can be released from HIV-1-infected cells and are oncogenic. All five are in a position to affect "innocent" bystander cells, specifically, to cause the propagation of (pre)existing malignant and malignant transformation of normal epithelial cells, giving grounds to the direct carcinogenic effects of HIV-1.

Abstract
BACKGROUND Anal cancer rates have increased, particularly in human immunodeficiency virus (HIV)-infected (HIV+) women. We assessed factors associated with anal precancer in HIV+ and at-risk HIV-negative women from the Atlanta Women's Interagency HIV Study cohort. METHODS All participants underwent high-resolution anoscopy and anal cytology and had anal and cervical samples collected. Specimens were tested for 37 human papillomavirus (HPV) types and for FAM19A4 and microRNA124-2 promoter methylation. Binary logistic regression and multivariate analysis were conducted with histologic anal high-grade squamous intraepithelial lesion (A-HSIL) as the dependent variable. RESULTS Seventy-five women were enrolled: 52 (69%) were HIV+ with three-fourths having undetectable viral load; 64 (86%) were black; mean age was 49 ± 8 years. Forty-nine (65%) anal cytology samples were abnormal, and 38 (51%) of anal samples were positive for at least 1 of 13 high-risk HPV (hrHPV) types. Thirteen (18%) anal biopsies identified A-HSIL. Hypermethylation of FAM19A4 and/or microRNA124-2 was found in 69 (95%) anal samples and 19 (26%) cervical samples. In multivariate analyses, the odds of having A-HSIL were >6 times higher in women with anal hrHPV (adjusted odds ratio [aOR], 6.08 [95% confidence interval {CI}, 1.27-29.18], P = .02) and with positive cervical methylation (aOR, 6.49 [95% CI, 1.66-25.35], P = .007), but not significantly higher in women with positive anal methylation. CONCLUSIONS Anal hrHPV and promoter hypermethylation in the cervix show promise as biomarkers for anal cancer screening in HIV+ and at-risk HIV-negative women. Greater understanding of gene silencing by promoter hypermethylation in anal carcinogenesis is needed.
