OBJECTIVES: to survey the prevalence of human papillomavirus, associated risk factors and genotype distribution in women who were referred to cervical cancer screening when attended in a Family Health Program. METHOD: we conducted a cross-sectional survey, investigating 351 women. Polymerase chain reaction for DNA amplification and restriction fragment length polymorphism analysis were used to detect and typify the papillomavirus. RESULTS: virus infection was detected in 8.8% of the samples. Among the 21 different genotypes identified in this study, 14 were high risk for cervical cancer, and the type 16 was the most prevalent type. The infection was associated with women who had non-stable sexual partners. Low risk types were associated with younger women, while the high risk group was linked to altered cytology. CONCLUSION: in this sample attended a Family Health Program, we found a low rate of papillomavirus infection. Virus frequency was associated to sexual behavior. However, the broad range of genotypes detected deserves attention regarding the vaccine coverage, which includes only HPV prevalent types.

Background: High-risk oncogenic human papillomaviruses (HPV) are the cause of sexually transmitted viral infection. Its persistence is a risk factor for precancerous lesions of the cervix, which will constitute the base of cervical cancer. In the world, the prevalence of high-risk oncogenic HPV is 66.7%, which is higher among women starting their sexual activity.Methods: An analytical cross-sectional study was conducted in high schools in Gabon regarding parents. The variables selected were the socio-cultural and demographic characteristics of the parents, their knowledge of human papillomavirus vaccination and their acceptability of HPV vaccination and finally the feasibility of HPV vaccination. The statistical test used was Pearson's Chi-square, and a difference was considered significant for p<0.05.Results: The majority of parents, 89%, were informed of the existence of cervical cancer. However, 73.4% of them were unaware of the existence of vaccination against cervical cancer. Only 2.4% of parents had vaccinated their daughters against cervical cancer at the time of the study. These parents only 53.4% expressed an interest in vaccinating their daughters in 53.4% of cases. The ability to vaccinate children is associated with the socio-professional status of parents (p˂0.000).Conclusions: The majority of parents approved school-based vaccination against human papillomavirus infections despite its reported cost and lack of information. The integration of anti-HPV vaccination into the expanded programme on immunization in Gabon will improve immunization coverage.

High-risk human papillomavirus (HPV) infection and viral persistence is a major risk factor in the development of squamous intraepithelial lesions and invasive carcinoma of the cervix. In the United States, deaths due to squamous cell carcinoma of the cervix have fallen by 75% since the 1960s because of Papanicolaou (Pap) smear screening. However, the traditional Pap had a sensitivity of about 70% for detecting clinically significant precancerous lesions and cancer because of sampling and interpretive errors. The introduction of 2 liquid-based Pap smear collection systems in the 1990s, the use of HPV testing as a triage and co-testing with Pap smear, and the introduction of 2 automated screening devices have had a significant impact on improving the detection of such precancerous lesions. This review provides an analysis of the changes in Pap smear collection, improvements in screening, the evolutionary changes of high-risk HPV testing, reporting terminology of Pap smears, and clinical management guidelines. The future impact of 2 prophylactic HPV vaccines on the incidence of cervical carcinoma is also discussed. This article also discusses alternatives such as primary screening for high-risk HPV testing with visual inspection for cervical cancer detection used in resource-poor settings with a high incidence of cervical cancer.

Abstract Background: Human papillomavirus (HPV) infection is currently the main cause of cervical cancer and precancerous lesions in female patients. By analyzing 6-year patient data from Shanghai Zhoupu Hospital in China, we retrospectively analyzed the epidemiological characteristics of women to determine the relationship between HPV genotype and cytological test results.Methods: From 2014 to 2019, 23,724 cases of cervical shedding were collected from Zhoupu Hospital in Shanghai, China. By comparing the results of HPV and ThinPrep cytology test (TCT), the HPV infection rate of patients was retrospectively analyzed. HPV genotyping using commercial kits can detect 21 HPV subtypes (15 high-risk and 6 low-risk). According to the definition of the Bethesda system, seven types of cervical cytology results were involved.Results: 3,816 among 23,724 women, nearly 16.08%, were infected with HPV. The top three highest HPV prevalence rates were high-risk type infection, including HPV52 (3.19%), 58 (2.47%) and 16 (2.34%). The number of single-type HPV infections (3,480 (91.20%)) was much larger than the number of multi-type ones (336 (8.8%)). Single-type infections were mainly in women aged 50-60 (16.63%) and women under 30 (15.37%), while multi-type infections were more common in women over 60 (2.67%). By analyzing the long-term trends, between 2014 and 2019, HPV52, 58, and 16 subtypes changed significantly, and the HPV positive rate also changed significantly during this period.Among 4,502 TCT positive women, 15 (4.04%), 125 (2.64%) ,159 (1.54%), 4,202(17.71%) and 1(0.004%) had atypical glandular cells (AGC), high-grade squamous intraepithelial lesions (HSIL), low-grade squamous intraepithelial lesions (LSIL), atypical squamous cells (ASC)and cervical adenocarcinoma, respectively. The HPV infection rates were 66.08%, 63.99%, 115.20%, 119.50%, and 31.72% for NILM, AGCs, HSILs LSILs and ASCs, respectively.Conclusions: HPV and TCT screening were very important steps in the secondary prevention of cervical cancer. Through the tracking and analysis of HPV and TCT results in this study, it can provide valuable information for Shanghai's HPV screening and prevention strategies, and provide references for clinical decision-making in the treatment of cervical cancer and precancerous lesions.

Background: In India, cervical cancer is second most common cancer in women and is the second most common cause of death due to cancers in women. Human papillomavirus (HPV), mainly genotype 16 and 18, are responsible for most of the precancerous lesions of cervix and for cervical cancer. Therefore, it is necessary to prevent the spread of HPV infection and its early treatment to decrease cervical cancer associated morbidity and mortality. Aims of this study was to find out the prevalence and distribution of various HPV genotypes in women high risk for cervical carcinoma. To find correlation between HPV DNA test and cytology report.Methods: An observational study was done on a total of 384 women who were at a high risk for cervical cancer.  Ectocervix and endocervix samples for conventional cytology along with cervical swab collection for HPV DNA isolation were obtained from women aged 21-65 years. Multiplex real time PCR used for HPV DNA isolation and genotyping and Bethseda classification 2014 was used for reporting cytology. Statistical analysis was done using SPSS version 22 and Microsoft excel 2010 software. Data assessment was done using independent t-test, Chi-square test or Fisher’s exact test.Results: Prevalence of HPV in women high risk for cervical cancer in our study was 14.58%. Most common high-risk genotypes were HPV 18 (7.03%) followed by HPV 16 (6.51%). All genotypes except genotype 31, were more frequently seen as a single infection rather than a multiple infection. In 323 subjects which were negative for Pap smear, 31 were positive for HPV DNA showing a statistically significant result with a p value of <0.0001.Conclusions: It was analysed that infection with HPV is very common (9.60%) even in women who had a negative Pap smear test showing a positive correlation between the two tests. HPV DNA testing can improve the detection rate of cervical intraepithelial lesions.

Abstract Objective: To determine the conformity of human papillomavirus between self-examination of vaginal specimen and cervical specimen with fluid-based cytology in precancerous lesions. Methods: A cross-sectional study performed on cervical and vaginal fluid from 90 pre-cancerous lesions patients from April to September 2016. Cytological examination performed with self-examination and liquid-based cytology technique. HPV genotyping performed with PCR technique. Data were analyzed with SPSS. Results: Most of the women aged >35 years (89%), 78% (71/90) multiparity and 74.4% (67/90) do not know about HPV screening. High risk type found in both vaginal and cervical fluid was type 16, 18, 33 and 45 whereas type 35 found only in vaginal fluid. The most prevalent high-risk HPV for both specimens were type 16 and 18. HPV type 42 and 53 were the low risk HPV found in the vaginal and cervical specimens (table 2). Cohen’s kappa for inter-test agreement shows a strong correlation (r=0.864). Conclusion: The HPV self-examination method can be used as a primary examination of cervical cancer lesions detection in addition to fluid-based cytology with the similar results. Keywords: Human papillomavirus, self-examination, fluid-based cytology, cervical cancer   Abstrak Tujuan: Untuk mengetahui tingkat kesesuaian antara pemeriksaan HPV mandiri dari spesimen vagina dan hasil pemeriksaan sitologi berbasis cairan dari spesimen serviks. Metode: Penelitian cross-sectional dilakukan pada cairan serviks dan vagina dari 90 pasien lesi pra-kanker pada April sampai September 2016. Pemeriksaan sitologi dilakukan dengan pemeriksaan diri dan teknik sitologi berbasis cairan. Pemeriksaan genotip HPV dilakukan dengan teknik PCR. Data dianalisis dengan SPSS. Hasil: Sebagian besar wanita dalam penelitian iniaberusia >35 tahun (89%), 78% (71/90) multiparitas dan 74,4% (67/90) tidak mengetahui tentang skrining HPV. Tipe HPV risiko tinggi yang ditemukan pada cairan vagina dan serviks adalah tipe 16, 18, 33 dan 45 sedangkan tipe 35 hanya ditemukan pada cairan vagina. Tipe HPV risiko tinggi yang dominan untuk kedua spesimen adalah tipe 16 dan 18. HPV tipe 42 dan 53 adalah HPV risiko rendah yang ditemukan pada baik spesimen vagina maupun serviks. Kappa Cohen untuk tingkat kesesuaian antara pemeriksaan mandiri dan sitologi berbasis cairan menunjukkan korelasi kuat (r = 0,864). Kesimpulan: Metode pemeriksaan HPV secara mandiri sendiri dapat digunakan sebagai pemeriksaan primer deteksi lesi kanker serviks selain sitologi berbasis cairan dengan hasil yang sama.
