Prevalence and Genotype Distribution of High-Risk Human Papillomavirus Types Compared with Cervical Cytology

Data of HPV genotype including 16 high-risk HPV (HR-HPV) and 4 low-risk HPV from 38,397 women with normal cytology, 1341 women with cervical cytology abnormalities, and 223 women with ISCC were retrospectively evaluated by a hospital-based study. The prevalence of high-risk HPV (HR-HPV) was 6.51%, 41.83%, and 96.86% in women with normal cytology, cervical cytology abnormalities, and ISCC, respectively. The three most common HPV types were HPV-52 (1.76%), HPV-16 (1.28%), and HPV-58 (0.97%) in women with normal cytology, whereas the most prevalent HPV type was HPV-16 (16.85%), followed by HPV-52 (9.55%) and HPV-58 (7.83%) in women with cervical cytology abnormalities. Specifically, HPV-16 had the highest frequency in ASC-H (24.16%, 36/149) and HSIL (35.71%, 110/308), while HPV-52 was the most common type in ASC-US (8.28%, 53/640) and LSIL (16.80%, 41/244). HPV-16 (75.78%), HPV18 (10.31%), and HPV58 (9.87%) were the most common types in women with ISCC. These data might contribute to increasing the knowledge of HPV epidemiology and providing the guide for vaccine selection for women in Shantou.

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.

Abstract Background: High-risk human papillomavirus (HR-HPV) infection is widely known as the major cause of cervical intraepithelial neoplasia (CIN) and cervical cancer and it’s characteristics vary greatly in different population. Women with abnormal cervical cytology could increase the risk of cervical cancer, however, HR-HPV infection characteristics in women with abnormal cervical cytology remains unclear. Methods: This study was based on baseline survey of the CIN Cohort established in Shanxi Province, China. A total number of 2300 women with cervical abnormalities were enrolled in this study. All participants gave informed consent and agreed to HPV and thinprepcytologic test (TCT). Each individual completed a questionnaire about characteristics related to HPV infection. Results: The overall prevalence of HR-HPV in 2300 women was 32.0%, and the proportion of single and multiple HR-HPV infections were 70.2% and 29.8% in HR-HPV infection women, respectively. The top five HR-HPV genotypes were ranked as HPV16, HPV58, HPV52, HPV53 and HPV51. The prevalence of HR-HPV in atypical squamous cells of undetermined significance (ASC-US), low-grade squamous intraepithelial lesion (LSIL) and high-grade squamous intraepithelial lesion and above(HSIL+) were 30.8%, 36.5% and 54.9%, respectively, showing an increasing trend with the severity of cervical cytology ( χ 2 trend =13.952; p <0.001). The women aged 35~45 years, with lower education level, less frequency of bathing, multiple gravidity, multiple parity, history of gynecological diseases and premenopausal women were prone to HR-HPV infection. Conclusions: We defined the characteristics related to HR-HPV infection in abnormal cervical cytology women, and provided an insight for the development and deeply research of HPV vaccine.

Sex With Men

Abstract Background: Homosexual men or men who have sex with men (MSM) are at increased risk of human papillomavirus (HPV) infection because of their high-risk sexual behaviors. In this large study, a meta-analytic approach was used to systematically analyze the literature to elucidate the prevalence and genotype distribution of anal, penile, oral, and urethral HPV infection among MSM in the world.Methods: To carry out this systematic review, five electronic databases were searched for relevant studies published from January 2012 through to November 2019, and pertinent data were collected from the eligible articles. The pooled HPV prevalences were calculated for each anatomical region using random-effect model weighted by the inverse variance method. Subgroup analyses were performed to identify the probable sources of heterogeneity. The meta-analysis was performed using the “Metaprop” function in the R package Meta.Results: The overall pooled prevalence of anal, penile, oral, and urethral HPV infection among MSM were 78.11 % (95% CI: 75.50%-80.52%), 36.26% (95% CI: 29.13%–44.05%), 17.33% (95% CI: 13.65%–21.75%), and 15.40% (95% CI: 7.86%–27.97%), respectively. Stratified analyses showed that the prevalences of HPV were significantly higher in HIV-positive than HIV-negative MSM. The most frequent HPV high-risk type detected in the anus, penis, and oral cavity was HPV-16 (20.32%, 4.96%, and 3.16%, respectively). Conclusion: HPV infection is on the dramatic rise in MSM because of high-risk sexual behaviors, strongly suggesting the increased risk of developing HPV-related diseases and malignancies in this population. Among different sexual orientations, male homosexuality is associated with the highest risk of acquiring sexually transmitted infections.

The objective of this study was to compare the sensitivity and specificity of a new method for self-sampling for high risk human papillomavirus (HPV) with direct sampling and liquid based cervical cytology. In Shanxi Province, China, 8,497 women (ages 27–56) underwent a self-sample for HPV using a conical-shaped brush placed into the upper vagina and rotated. Three to sixteen months later the women were screened with liquid-based cytology and direct HPV tests. Subjects with any abnormal test underwent colposcopy and multiple biopsies. Mean age was 40.9 years. 4.4 percent of subjects had ≥CIN II, 26% a positive self-sample and 24% a positive direct test for HPV. The sensitivity for detection of ≥CIN II was 87.5% for self-sampling, and 96.8% for the direct test (P < 0.001). The specificity was 77.2% for the self-sample and 79.7% for the direct test. With an abnormal Pap defined as ASCUS or greater the sensitivity of the Pap for the detection of ≥ CIN II was 88.3% and the specificity was 81.2%. We conclude that self-sampling for HPV is less sensitive for ≥ CIN II than the direct test, but similar to liquid based cytology.
