Prevalence of Precancerous Lesions Based on Digital Cervicography with VIA/VILI among Women Positive for High-Risk Human Papillomavirus Serotypes: A Screening Center-Based Study in Cameroon

Background: Since 2021, high-risk Human Papilloma Virus (HR-HPV) testing has been the recommended screening test for cervical cancer for all settings;either used alone in a “test and treat” strategy, or with a triage test, with or without biopsy, before treatment. Cameroon has rolled out immunization against HPV 16 and 18, but studies show a higher prevalence of non-16/18 HR-HPV types. Objectives: Determine the prevalence of precancerous lesions, in women with HR-HPV infection and evaluate association of digital cervicography (DC) VIA/VILI positivity with HPV serotype, as a measure of their contribution to precancer and cancer incidence. Methodology: The study was cross-sectional, descriptive, and analytic. It took place at the Etoug-Ebe and Ekoudoum Baptist Hospitals in Yaoundé, during the period April-September 2022. We reviewed the records of women screened for cervical cancer between February 2020 and December 2021 and evaluated the prevalence of lesions on digital cervicography (DC) with VIA/VILI for women positive for HR-HPV serotypes. The data were analyzed using SPSS version 20.0 for Windows. P values Results: We identified 315 cases with a positive HR-HPV deoxyribonucleic acid (DNA) test, 224 (71.1%) had a DC VIA/VILI triage test done. Of these, 30 (13.4%) women had a positive DC VIA/VILI, with five women (2.2%) having lesions suggestive of cancer. Out of 11 cases positive for HPV 16 alone, 05 (45.5%) had a positive DC VIA/VILI test. Of the 14 cases positive for HPV 18 alone, 03 (21.4%) had a positive VIA/VILI, meanwhile only 19 (10.7%) of the 177 cases positive for non-16/18 HPV had a positive VIA/VILI test. Conclusion: A high proportion of women (13.4%) with HR HPV had a positive DC VIA/VILI, with a significant proportion (2.2%) having lesions suggestive of invasive cervical cancer HR-HPV serotype was associated with DC VIA/VILI positivity;HPV 16 had the strongest association (45.5%), followed by HPV 18 (21.4%), and non-16/18 HR-HPV (10.7%), suggesting a decreasing order of oncogenicity.

Analysis of Human Papillomavirus Infection in Cervical Exfoliated Cells

To screen patients with early cervical lesions by analyzing the infection of high-risk Human papillomavirus (HR-HPV). Research Methods: The cervical exfoliated cell specimens and their clinical data were collected. The HPV infection types of the collected specimens were detected by fluorescence quantitative PCR, and the correlation between HPV infection and clinicopathological features was analyzed statistically. Results: 725 cases were HR-HPV positive from 2605 cases, including 15 high-risk types of HPV16, 18, 31, 33, 35, 39, 45, 51, 52, 53, 56, 58, 59, 66, 68. Different histological types ranged from NILM to HSIL, and the positive rate of HPV showed an increasing trend with the aggravation of cervical lesions. Conclusion: The positive rate of 15 high-risk HPV types in the collected specimens was 27.8%. Patients with early cervical lesions could be screened for 15 high-risk HPV infection types.

Efficacy of 2LPAPI®, a Micro-Immunotherapy Drug, in Patients with High-Risk Papillomavirus Genital Infection

Human papillomaviruses (HPVs) are well known for being linked to the development of cervical cancers, most of them being caused by the high-risk (HR) oncogenic genotypes, mainly 16 and 18. The efficacy of 2LPAPI® (Labo’Life), a micro-immunotherapy homeopathic drug, has been evaluated in HR-HPV infected women (n = 18), in a private gynecology practice, by comparing them to an untreated control group (n = 18). Patients were 20 to 45 years old and had cytology with Atypical Squamous Cells of Undetermined Significance (ASCUS) or Low grade Superficial Intra Lesions/ Cervical Intraepithelial Neoplasia Grade I (LSIL/CINI). Patients freely chose to be treated with the drug or not. Those deciding not to take the drug remained untreated and were followed as a control group. The drug was taken at the regimen of one capsule per day during 6 months. HR-HPV and cytology were evaluated at 6 and 12 months. After 12 months, HR-HPV was cleared in 78% of the patients taking the drug versus 44% in those not taking it (p = 0.086). In patients over 25 years, HR-HPV clearance in the treated group was significantly higher (81.3%) than in the control group (20%) (p = 0.004). The difference in the regression of the lesion grades almost reached statistical significance (p = 0.053). This follow-up confirms that the micro-immunotherapy drug 2LPAPI® is a safe and effective therapeutic approach to treat HR-HPV cervical lesions in women over 25 years.

Study on the Correlation between Human Papillomavirus and Mycoplasma genitalium Combined with TCT Detection

Objective: This study aims to explore the correlation between human papillomavirus (HPV) and Mycoplasma genitalium (CT) combined with TCT detection in cervical cancer screening. Method: A cross-sectional study design was adopted, and a total of 609 women who came to seek medical treatment were recruited as the study subjects. Combination testing was evaluated on cervical cancer screening by testing the women for HPV, CT with TCT detection and analyzing the relationship of cervical lesions with HPV and CT infection. Results: The study results showed that 21.57% of the subjects were infected with both HPV and CT, and 48.42% of the cases had abnormal TCT results at the same time. Further data analysis showed that HPV infection was significantly associated with abnormal TCT outcomes (p < 0.05), suggesting a possible synergistic effect of the two infections in cervical lesions. The combined sensitivity and specificity of HPV, CT and TCT detection were 21.57% and 48.42%, respectively, which were significantly higher than that of single detection. Conclusion: In summary, the results of this study support the importance of combined HPV, CT, and TCT testing in cervical cancer screening, and propose the hypothesis that combined testing may improve screening effectiveness. However, further large sample studies are needed to confirm this conclusion and explore the prospects of combined testing in clinical practice.

The effect of HPV infection on mental health status in women

Human papillomavirus(HPV)infection is one of the most common sexually transmitted infections globally,and its close association with the development of cervical cancer has become a major public health concern.HPV infection not only leads to physical health problems,but also has an impact on a woman’s mental health,such as:severe anxiety,fear,depression,negativity,and other psychological distress.The purpose of this review is to systematically summarize the current knowledge on this topic and to explore its current development in accordance with the PRISMA guidelines.We can provide interventions that may alleviate or even eliminate psychological problems in women,depending on their psychological characteristics.A total of 82 records were included in the study,including 37 papers on the effect of HPV infection on the mental health status of women and 45 studies on the effect of implementing interventions on the mental health of patients with HPV infection.The results show that HPV infection can make women produce anxiety,depression,shame,low self-esteem and other negative psychological.However,active and proper medical treatment,psychological counseling and support,and strengthening health education have positive effects on HPV-infected women,and can promote the mental health of HPV-infected women.

Distribution of High-Risk Human Papillomavirus Genotypes among Women with Colposcopic Diagnosis of Cervical Intraepithelial Neoplasia in Bangladesh

Background: The incidence of cervical cancer is high in Bangladesh and there is a high prevalence of preinvasive lower genital tract disease among women of reproductive age. Persistent high-risk Human Papilloma Virus (HPV) infection is the main underlying cause of cervical cancer and its precursor, cervical intraepithelial neoplasia (CIN). Objective: The aim of the study was to identify the subtypes of high-risk HPV infection among women with the colposcopic diagnosis of cervical intraepithelial neoplasia in Bangladesh. Methods: This cross-sectional observational study was conducted in the colposcopy clinic of Dhaka Medical College Hospital over a six-month period. A total of 100 participants were enrolled. Married women, between 30 - 60 years of age with colposcopically diagnosed cervical intra epithelial neoplasia were enrolled. Women with chronic illness, pregnancy, and women unable to consent were excluded from this study. After counselling, colposcopically directed punch biopsies were taken from each CIN case concurrently with high-risk HPV testing by polymerase chain reaction (PCR). Results: The mean age of the patients was 38.69 (SD ±7.76) years. CIN 1 was diagnosed in 57% of participants, while 24% had CIN II and 19% had CIN III lesions. High-risk HPV was present in 52 patients. HPV 16 was the most common identified in 28 (53.84%) and HPV 18 was the second most common with 20 (38.46%) either singly or in combination with other high-risk subtypes. The other HPV strains, HPV 31, 33, 35, 52, 56 and 58, were also detected either as mono or co-infections. Out of the 52 HPV positive cases, 29 (55.8%) had mono infection and 23 (44.2%) had co-infection with several subtypes. The highest incidence (50%) of oncogenic HPV infections was present among women aged 35 - 45 years. Risk factors associated with HPV positive cases were high parity (P 0.05), early age at marriage (P = 0.754) and early age of first child. Conclusion: This study identified a high prevalence of HPV 16 and 18 genotypes. HPV vaccination with the current 9-valent HPV vaccine, which contains HPV types 6, 11, 16, 18, 31, 33, 45, 52, and 58. Will be an effective public health measure to eradicate cervical cancer in Bangladesh.

Progress in the Research on the Relationship between Infection with Human Papillomavirus and Tumorigenesis

Human papillomavirus(HPV) is a DNA virus that infects the skin and mucous membranes of the human body. Approximately 80% of sexually active women are likely infected with HPV. Cervical cancer is one of the most common malignant tumors and is second in incidence only to breast cancer. Infection with high-risk HPV types is the main risk factor for cervical cancer, which is currently the only malignant tumor with a clearly defined etiology. HPV infection is also closely related to the incidence and development of other malignant tumors. In addition to cervical cancer, HPV can cause other urogenital tumors, as well as tumors in the digestive tract, lungs, eyes, skin, and other organ systems. This paper provides a review of the progress in HPV infection-related research and provides novel ideas for the study of tumor etiology and mechanisms.

Co-infection of Epstein-Barr virus and human papillomavirus in human tumorigenesis

Viral infections contribute to approximately 12%of cancers worldwide,with the vast majority occurring in developing countries and areas.Two DNA viruses,Epstein-Barr virus(EBV) and human papillomavirus(HPV),are associated with38%of all virus-associated cancers.The probability of one patient infected with these two distinct types of viruses is increasing.Here,we summarize the co-infection of EBV and HPV in human malignancies and address the possible mechanisms for the co-infection of EBV and HPV during tumorigenesis.

Malakoplakia of the esophagus caused by human papillomavirus infection

Malakoplakia is a rare granulomatous disease probably caused by infection and characterized histologically by Michaelis-Gutmann bodies.We report a more rarely seen case esophageal malakoplakia in a 54-year-old woman.She presented with coughing while eating and drinking.Gastroscopy showed yellow nodules in the esophagus,and endoscopic ultrasonography showed a space-occupying lesion in the substratum of the esophageal mucosa.All findings highly resembled esophageal cancer.Histopathological examination finally indentified this space-occupying lesion as malakoplakia and not cancer.Immunohistochemistry showed that she had human papillomavirus(HPV) infection in the esophagus,which indicates that infection was responsible for the malakoplakia.This is believed to be the first case of malakoplakia in the esophagus,and more importantly,we established that HPV infection was the initiator of esophageal malakoplakia.

Prevalence and Determinants of High-risk HPV Infection among 11549 Women from an Opportunistic Screening in Hubei Province

High-risk human papillomavirus (hrHPV) infection plays an important role in the development of cervical intraepithelial neoplasia and cervical cancer.A total of 11 549 women were enrolled from the Maternal and Child Health Hospital of Hubei Province.Each participant accepted hrHPV testing and completed a self^administered questionnaire about basic information and potential risk factors.The univariable and multivariable logistic regression model was used to explore the associations between variants and hrHPV infection.Our results showed that hrHPV prevalence was 16.09% in Hubei Province,among which,hrHPV was more likely to be positive in women aged 51 years or above (OR=1.65,95% CI:1.28-2.14),and in women who had symptoms of bleeding after intercourse (OR=1.32,95% CI:1.17-1.50),had first sexual intercourse at the age of 18 years or below (OR=1.33,95% CI:1.07-1.64),had at least three male sexual partners (OR=2.50,95% CI:2.07-3.03),and who had been diagnosed with sexually transmitted infections (OR=1.50,95% CI:1.12-2.03).Married women (OR=0.66,95% CI:0.55-0.78) and women who frequently used condoms (OR=0.75,95% CI:0.67-0.84) had a relatively lower hrHPV prevalence.This study confirms that hrHPV infection was associated with age,marital status,symptoms of intercourse bleeding,history of sexually transmitted infections,and sex-related behaviors.Above all,this study provides a baseline database prior to obtaining vaccinations for dynamic tracking of the changes in hrHPV prevalence.

Anal Invasive Squamous Cell Cancer and Human Papillomavirus Distribution in HIV-Infected and Non-HIV-Infected Individuals

Invasive-squamous-cell-cancer (ISCC) of the anal canal is an uncommon disease. Human papillomavirus (HPV) is the etiological agent of most of types of ISCC. The incidence of ISCC has been increasing in HIV-infected individuals, even after the introduction of highly active antiretroviral therapy. The aim of this study was to analyze biopsy specimens from patients diagnosed with ISCC at a tertiary hospital from 1983 to 2012 in order to detect HPV-DNA. Methods: Formaldehyde-fixed, paraffin-embedded specimens from patients with ISCC underwent HPV-DNA genotyping using multiplex PCR assay. Results: A total of 31 cases were collected;10 were HIV-infected (9 men, 1 woman) and 21 non-HIV-infected (11 men, 10 women). HPV infection was detected in 87.5% (7/8) of the HIV-infected patients (DNA from 2 biopsies was degraded) and 76.2% (16/21) of non-HIV-infected individuals. Multiple-type infections were only found in 28.6% (2/7) of the HIV-infected patients (no multiple-type infections in non-HIV-infected individuals). The most prevalent type was HPV-16: 50% (4/8) in the HIV-infected group (57% [4/7] of the HPV-positive samples) and 66.7% (14/21) in the non-HIV-infected group (87.5% (14/16) of the HPV-positive samples). Remarkably, 37.5% (3/8) of the HIV-infected group had high-risk HPV types not included in the vaccines (HPV-33, 51, 52, and 66) compared with 4.8% in the non-HIV-infected group (1/21, HPV-52). All cases of anal ISCC in HIV-infected patients were recorded in the highly active antiretroviral therapy era. Conclusion: HIV-infected patients presented anal ISCC with a higher proportion of high-risk HPV types not covered by the conventional vaccines than non-HIV-infected individuals.

Integration of human papillomavirus 18 DNA in esophageal carcinoma 109 cells

AIM:To detect human papillomavirus(HPV) DNA in esophageal carcinoma(EC) 109 cells and investigate the relationship between HPV and EC.METHODS:Genomic DNA and total RNA from EC109 cells were isolated.HPV DNA was detected by polymerase chain reaction(PCR) with the general primer sets of My09/11 and GP5 +/6 + for the HPV L1 gene and type-specific primer sets for HPV18 E6 and HPV18 E6-E7.Reverse transcription(RT) of mRNA isolated from EC109 cells was performed to produce a cDNA.And then a PCR-based protocol for the amplification of papillomavirus oncogene transcripts was used to analyze HPV18 DNA and integrated transcripts of HPV18 in the chromosomes of EC109 cells.The final nested PCR products were cloned into a pMD-18T vector and sequenced to analyze the chromosomal location of HPV integration.RESULTS:HPV18 DNA was detected in EC109 cells by PCR using the general primer sets of My09/11 and GP5 +/6 + for HPV L1 and the type-specif ic primer sets for HPV18 E6 and E6-E7 to generate products of 450 bp,150 bp,335 bp and 944 bp,respectively.Approximately 600 bp of integrated HPV18-specific transcript was identified.The final nested PCR product of integrated HPV18 DNA was cloned into a pMD-18T vector and sequenced to analyze the chromosomal location of HPV integration.Sequence alignment showed that the HPV18 sequence from EC109 cells was identical to that of the encoded early protein E7-E1 of the standard HPV18 strain X05015,and another partial gene sequence was identical to a partial sequence of human chromosome 8.CONCLUSION:Integration of the HPV genome into the host cell chromosome suggests that persistent HPV infection is vital for malignant cell transformation and carcinogenesis.

ROLE OF COLPOSCOPY IN THE DIAGNOSIS OF HUMAN PAPI- LLOMAVIRUS INFECTION OF THE UTERINE CERVIX

Among 6706 women screened by cytology, only 9 (0.13%) showed evidence of human pppillomavirus infection (HPVI). In 133 women examined by colposcopy for abnormal cytology or/ and suspected lestions on the cervix, 41.(30. 8%) showed subclinical papillomavirus infection (SPI), while 17. 4% and 5. 3% showed HPVI by histopathology and cytology, respectively. The conformation rate between colposcopy and pathology was 69. 6%. Sixty-nine specimens out of 133 colposcopy piled biopaies were assayed by HPV-DNA dot hybridization with 6B/11, 16, 18 probes to detect the presence of HPV-DNA In the cervical specimens. Thirty-nine (56.5%) gave a positive result. The colposcopic predictive value of positive result for HPVI was 76.7%. The difference between colposcopy (59%) and pathology (20. 5%) is statistically significant (P<0. 01). These results suggest that colposcopy is superior to cytology and hjstopathology for the detection of SPI in the cervix. In colposcopy HPV-DNA positive women, aceto while epithelium was most common (28. 2%) . As it is difficult to differentiate SPI from cervical intraepithelial neoplasia especially the Grade Ⅰ lesion by colposcopy, discrimination criteria are proposed together with the chief colposcopic features of SPI.

Human papillomavirus-associated diseases and cancers

Human papillomaviruses(HPVs) have been detected in cervical cancer cells and skin papilloma cells, which have a variety of types, including low-risk and high-risk types. HPV genome replication requires the host cell's DNA synthesis machinery, and HPVs encode proteins that maintain differentiated epithelial cells in a replication-competent state. HPV types are tissue-specific and generally produce different types of lesions, either benign or malignant. This review examines different HPV types and their associated diseases and presents therapeutic options for the treatment of HPV-positive diseases.

Relevant Frequency of Multiple Infections with High- and Low-Risk HPV Genotypes among Mexican Women Attending a Tertiary Care Hospital

Aims: To assess the frequency and the main HPV genotypes circulating among a group of women attending at a third level Hospital in Mexico City. Methods: A cross-sectional and descriptive study was performed in a group of 143 female outpatients of the Gynecology and Obstetrics Service at the National Institute of Perinatology of Mexico. Cervical swabs were taken from participants and subjected to simultaneous detection/genotyping of HPV by Linear Array Genotyping Test (Roche Molecular Systems). Mann-Whitney U, median and/or Square Chi tests were used to compare socio-demographical features between HPV-infected and uninfected women. Results: A total of 66 women (46.2%) had HPV infection. Overall, 112 genotypes were detected either as single infections (45.5%) or multiple genotype infections (54.5%). The cumulated frequency of multiple infections with high-/low- and high-/high-risk HPV genotypes was 63.9 %. The most frequent high-risk genotypes were HPV52 HPV58 and HPV51, whereas the most frequent low-risk genotypes were HPV6, HPV53 and HPV84. Infected women were significantly younger and have less stable partner relationships than uninfected women (p < 0.05). Conclusion: A relevant frequency of mixed infections with high- and low-risk HPV genotypes, other than those considered most prevalent worldwide, was observed. Most circulating high-risk genotypes among the women of this study are not covered by commercial vaccine formulations.

Correlation of HPV infection with TLRs pathway activation and downstream gene expression in cervical precancerous lesions

Objective: To study the correlation of HPV infection with TLRs pathway activation and downstream gene expression in cervical precancerous lesions. Methods: Cervical precancerous lesion tissues from surgical resection or cone biopsy in Affiliated Traditional Chinese Medicine Hospital of Xinjiang Medical University between June 2014 and May 2017 were collected and divided into HR-HPV positive group and HR-HPV negative group according to the condition of high-risk HPV infection;normal cervical tissues surgically removed due to fibroid in Affiliated Traditional Chinese Medicine Hospital of Xinjiang Medical University during the same period were collected as the control group. The contents of TLRs pathway molecules as well as the expression of apoptosis-related genes and invasion-related genes in the cervical precancerous lesion tissues and normal cervical tissues were determined. Results:TLR2, TLR3, TLR4, TLR9 and NF-κB contents as well as CyclinD1, PCNA, iNOS, Gal-9, N-cadherin, HIF-1α and VEGF mRNA expression in HR-HPV positive group and HR-HPV negative group were significantly higher than those in control group whereas p53, Beclin1, LC3-II and SFRP2 mRNA expression were significantly lower than those in control group, and TLR2, TLR3, TLR4, TLR9 and NF-κB contents as well as CyclinD1, PCNA, iNOS, Gal-9, N-cadherin, HIF-1α and VEGF mRNA expression in HR-HPV positive group were significantly higher than those in HR-HPV negative group whereas p53, Beclin1, LC3-II and SFRP2 mRNA expression were significantly lower than those in HR-HPV negative group. Conclusion: HPV infection in cervical precancerous lesions can regulate downstream apoptosis and invasion gene expression by activating multiple TLRs pathways.
