Abstract
OBJECTIVE Persistent infection with high-risk human papillomavirus (HPV) is a key contributor to cervical intraepithelial neoplasia (CIN), but the relation between high-risk HPV genotypes and the location of CIN lesions remains unclear. The aims of this study were to investigate the most frequent biopsy site of CIN lesions in women with different HPV infection and to analyze the biopsy times, CIN frequency, and the clustering of CIN frequency based on 12-o'clock sites and cervical quadrant locations. MATERIALS AND METHOD We conducted a retrospective study of HPV detection and genotyping at the virology department of our hospital. Colposcopy exams were performed by specialists according to a standardized protocol, and all visually abnormal areas were further biopsied. Pearson chi-squared tests and cluster analyses were implemented to analyze the data. RESULTS Among 1,381 women enrolled in this study, 933 cases infected with HPV. HPV16, HPV58, and HPV18 were the most common genotypes. The most frequent biopsy site was the 6 o'clock position. The highest frequency of high-grade CIN findings in single-genotype HPV groups was the 6 o'clock position and that for multiple-genotype HPV group was the 12 o'clock location. All CIN clusters were found in the 6 and 12 o'clock biopsy sites, except in the HPV18 group. Quadrant 2 and 4 were clustered in most groups. CONCLUSIONS The 6 and 12 o'clock sites in cervical quadrant 2 and 4 should be targeted during cervical biopsy procedures. These findings can provide clinicians with specific recommendations on the optimal site for CIN biopsy when considering the HPV genotype.

Abstract
Background Cervical cancer is primarily caused by HPV infection. The epidemiology of HPV infection in specific areas is of great meaning of guide cervical cancer screening and formulating HPV vaccination strategies. Here, we evaluated the epidemiological characteristics of HPV infection in Xiamen population. Methods In total, 159,049 cervical exfoliated cell samples collected from female outpatients in Women and Children's Hospital, School of Medicine, Xiamen between January 2013 and July 2023 were analyzed. HPV DNA detection was performed using HPV genotyping kits (Hybribio Limited Corp, China). An analysis was conducted on the prevalence of HPV infection, taking into account factors such as age, year, and multiple patterns of HPV infection. The differences in prevalence among age groups and years were compared using χ2 test. Results The overall prevalence of any 21 HPV genotypes was 18.4%, of which the high-risk HPV (HR-HPV) positive rate was 14.6%. The age-specific prevalence of HPV infection showed a bimodal distribution, with two distinct peaks, one at <25 years (31.2%) and the other at 60-64 years (32.9%). There was a downward trend in the prevalence of HPV infection over time, decreasing from 26.2% in 2013 to 14.5% in 2021, and then increasing to 19.0% in 2023. The five most prevent HR-HPV genotypes were HPV52 (4.0%), 58 (2.6%), 16 (2.5%), 51 (1.8%), and 39 (1.7%). Among the positive cases, 76.7% were detected with only one genotype and 23.3% with multiple genotypes. The most common co-infection was HPV52 + HPV58 (0.24%), followed by HPV16 + HPV52 (0.24%), HPV52 + HPV53 (0.21%), HPV52 + HPV81 (0.21%), HPV51 + HPV52 (0.19%), HPV16 + HPV58 (0.18%), and HPV39 + HPV52 (0.17%). Conclusion The study provided the largest scale information on the recent epidemiological characteristics of HPV infection in Xiamen, and even in Fujian Province, China, which would support making the prevention and control strategies for cervical cancer in the region.

Genetic variability analysis of human papillomavirus 58: Novel sublineage identification and persistent infection association. J Med Virol 2023; 95:e29262. [PMID: 38037452 DOI: 10.1002/jmv.29262] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2023] [Revised: 10/20/2023] [Accepted: 11/12/2023] [Indexed: 12/02/2023]
Abstract
This study aims to characterize the genetic variability of HPV58, identify novel lineages and sublineages, and explore the association between persistent/multiple HPV58 infections and genetic variation. In this study, samples from 124 women with HPV58 infection in Eastern China were collected and 81 isolates of E6 and L1 full-length genes were successfully amplified from 55 samples. We evaluated the diversity of genetic variants and performed correlation analyses between genetic variability and pathology, vaccination, multiple infections, and persistent infections. Among the E6 and L1 gene sequences collected, the dominant prevailing sublineages were A1 (46.2%) and A2 (23.1%). In addition, we found two potential novel sublineages denoted as the A4 and A5 sublineage. A total of 50 nucleotide substitutions, including 28 synonymous substitutions and 22 nonsynonymous substitutions, were observed in the E6 and L1 genes. Among them, variants with A388C/K93N substitutions in the E6 gene correlated with persistent infection (≥1 and ≥2 years) (p < 0.005), and C307T/C66C was associated with persistent infection (≥2 years) (p < 0.005). Notably, two mutations above were detected in the isolate from the patient with breakthrough vaccine infection. Our study found two novel sublineages and sites of genetic variability in multiple and persistent infection variants. In addition, we identified two mutational sites associated with persistent infection. This study provides new insight into the clinical characteristics of HPV 58 genetic variations and offers new ideas for research on next-generation vaccines in Eastern China.

Abstract
OBJECTIVE To investigate the infection status of high-risk human papillomavirus (HR-HPV) E6/E7 mRNA in patients with a cytological diagnosis of "atypical squamous cells of undetermined significance" (ASCUS) and to analyze the pathogenic rate of different high-risk HPV subtypes combined with biopsy pathological results to provide a more accurate basis for managing ASCUS patients. METHODS A total of 1387 patients with ASCUS and HPV E6/E7 mRNA positivity who were referred for colposcopy were retrospectively analyzed. They were divided into HPV16+, 18/45 + and other HR-HPV + groups premenopausal and postmenopausal groups. The pathological results of the biopsy were divided into the LSIL- group (including normal and low-grade squamous intraepithelial lesions) and the HSIL + group (including high-grade squamous intraepithelial lesions and higher lesions). SPSS was used for the analysis. RESULTS The age group 31-40 years had the highest level of HPV16+, and HPV18/45 + was the highest in the 41-50 years group. The detection rates of HSIL + in the HPV16+, HPV18/45+, HPV 16/18/45 + and Other HR-HPV + groups were 48.4%, 18.8%, 43.9% and 15.0%, respectively. The infection rates of HPV16/18/45 in postmenopausal and premenopausal women were 42.4% and 34.3%, respectively. In the HPV18/45 group, the incidence of HSIL + was 30.0% in postmenopausal women and 15.0% in premenopausal women (P < 0.01). In the HPV 16 + and Other HR-HPV + groups, the incidence of HSIL + in postmenopausal patients was not significantly different from that in premenopausal patients. The incidence of cervical cancer in postmenopausal patients is significantly higher than that in premenopausal patients. CONCLUSIONS Colposcopy referral or further biopsy is recommended for all ASCUS patients with HPV16/18/45E6/E7 mRNA positivity and postmenopausal patients with HR-HPVE6/E7 mRNA positivity. For premenopausal ASCUS patients with other HR-HPV E6/E7 mRNA positivity, colposcopy should be performed if possible, depending on the specific situation, to achieve early detection and diagnosis.

Abstract
OBJECTIVES To assess the efficacy and safety of focused ultrasound (FU) for high-risk human papillomavirus (HR-HPV) infection-related cervical low-grade squamous intraepithelial lesions (LSIL). METHODS Of 185 patients who met the inclusion criteria for this prospective study from October 2020 to November 2021, 95 received FU and 90 were followed up only. At the six-month follow-up, the HR-HPV clearance and LSIL regression rates of the groups were compared and factors affecting HR-HPV clearance were analyzed. The safety and side effects of FU were evaluated. RESULTS No significant difference was found in the baseline clinical data between the two groups (p > 0.05). At the six-month follow-up, the HR-HPV clearance rates were 75.6% in the FU group and 25.6% in the observation group (p = 0.000). The LSIL regression rates were 89.5% in the FU group and 56.4% in the observation group (p = 0.000). Multivariate logistic regression analysis showed that the HR-HPV clearance rate in the FU group was 9.03 times higher than that in the observation group (95% confidence interval [CI], 3.75-21.73, p = 0.000), and the clearance rate of single-type HR-HPV infections was 5.28 times higher than that of multi-type infections (95% CI, 1.83-15.23, p = 0.002). The mean intraoperative bleeding was 1.8 ± 0.6 (1-3) mL; the mean intraoperative pain score was 2.6 ± 1.0 (1-6). CONCLUSIONS For patients with HR-HPV infection-related histological LSIL, FU can eliminate HR-HPV infection and cause lesions to regress in a short time, with few adverse effects and good tolerance.

Abstract
Objective This study aimed to analyze the status of human papillomavirus (HPV) infections in women in Yunnan in the south of China and their correlation with the grade of cervical intraepithelial neoplasia (CIN). Methods A total of 281 patients with CIN and HPV infection, diagnosed at Kunming Kingmed Institute for Clinical Laboratory between January 2019 and June 2021, were enrolled as the subjects of the study and underwent HPV genotyping and cervical histopathology. Results The mean age of the 281 patients was 42.3 years, and the median age was 42 years. There were 79 patients in the low-grade squamous intraepithelial lesion (LSIL) group, and 202 patients in the high-grade squamous intraepithelial lesion (HSIL) group. The proportion of 30-45 years old in HSIL group was 58%. Overall, single infections accounted for 76%, and HR-HPV infections accounted for 90.1%. The most common HR-HPV subtypes in the two CIN groups were almost the same, including HPV16, HPV58 and HPV52. The most common LR-HPV subtype in the two CIN groups was HPV43. There were no significant differences in ethnic and single or multiple infection rates among different CIN groups. Single infection of HPV43 and HPV81 was found in minority HSIL patients. Conclusion HPV infection in Yunnan was dominated by single infection and HR-HPV. Patients aged 30 to 45 years were in the high incidence of HSIL, and the most common HR-HPV subtypes were HPV16, HPV58, and HPV52. Single LR-HPV infection exists in minority HSIL patients.

Abstract
OBJECTIVE The purpose of this study was to compare the efficacy of focused ultrasound (FU) and interferon drug therapy for cervical intraepithelial neoplasia 1 (CIN1) and chronic cervicitis associated with high risk human papillomavirus (HR-HPV) infection, as well as analyze the influencing factors. METHODS A retrospective cohort study was performed from January 2017 to December 2019. A total of 592 patients were enrolled, of which 300 patients were treated with FU and 292 patients were treated with interferon drugs. Kaplan-Meier curves and a COX regression model were used to compare the curative effects of the two therapeutic methods using HR-HPV clearance as the main outcome. The relationship between age, HR-HPV infection type, pathological type, preoperative HR-HPV status and HR-HPV clearance were also analyzed. RESULTS The median time for HR-HPV clearance was 6.00 months (95% CI: 5.24-6.76) in the FU group and 26.00 months (95% CI: 22.32-29.68) in the medication group. A significant difference was observed between the two groups (χ2 =198.902, p = 0.000). The HR-HPV clearance rate was 4.927 (95% CI 3.840-6.321; p = 0.000) times higher in the patients treated with FU than those treated with interferon drugs. In the FU group, no significant difference was observed in HR-HPV clearance rate between CIN1 and chronic cervicitis (χ2=0.660, p = 0.416), which was also insignificant between HR-HPV persistent and non-persistent infections (χ2=0.751, p = 0.386). CONCLUSION FU therapy can eliminate HR-HPV infections in a short period of time. Moreover, the treatment efficacy of FU was significantly superior to that of interferon drugs.

Abstract
We aimed to study the infection status and distribution of human papillomavirus (HPV) in Yangzhou City to provide precise guidance for the prevention and treatment of cervical cancer in this area. Reproductive tract secretions were collected from patients admitted at Subei People's Hospital over the past 3 years. Fifteen high-risk HPV (HR-HPV) genotypes were analyzed by fluorescent polymerase chain reaction. The positive rate of HR-HPV in 34 420 subjects was 23.56%. There was no significant difference in the rate of overall infection between males and females (χ 2 = 0.04; p = 0.952 > 0.05). The five genotypes with high infection rates in the population were HPV52, HPV58, HPV16, HPV51, and HPV39. Single infection was found to be dominant, primarily with the HPV52 genotype. The infection rate was higher in patients less than 20 years old and more than 60 years old. Most patients with cervical intraepithelial neoplasms 2/3 and cervical cancer were infected by HPV16, followed by those infected by HPV52 and HPV58. There was a significant difference in the infection rate of HPV16 among patients with different cervical lesions (χ 2 = 31.660; p < 0.01), and the infection rate of HPV16 was higher in patients with cervical cancer than in healthy individuals. Single infection was dominant among the study patients with HPV infection in Yangzhou city. There was no significant difference in infection rate and genotype distribution between males and females. The infection rate in young and old women was higher, and the rate increased with age (>20 years).

Abstract
Background Human papillomavirus (HPV) testing is more sensitive than cytology for detecting cervical cancer and its precursors. This study aimed to analyze the prevalence of high-risk HPV genotypes and evaluate the role of HPV genotyping triage for detecting high-grade squamous intraepithelial lesions, adenocarcinoma in situ and cervical cancer (HSIL+) in HPV-positive women with normal cytology. Methods A retrospective study was performed in women who had undergone co-screening at the China Medical University-affiliated Shengjing Hospital between 2012 and 2014. Results Of the 34,587 women, 2665 HPV-positive women with normal cytology who had received colposcopy were eligible for analysis. In HSIL+ groups of 204 women, the common genotypes were HPV16, HPV52, HPV58, HPV33, HPV31 and HPV18 in order of prevalence. The proportion of histological HSIL+ in women infected with HPV33 or HPV31 was not significantly different compared to women infected with HPV16 (P = 0.30, P = 0.19, respectively). The odds ratios for histological HSIL+ were 3.26 (95% confidence interval [CI]: 2.41–4.40) in women with HPV16/18, 4.21 (95% CI: 2.99–5.93) in those with HPV16/18/31/33, and 5.73 (95% CI: 3.30–9.97) in those with HPV16/18/31/33/52/58. Including HPV31/33 genotyping together with HPV16/18 significantly increased the proportion of HSIL+ detection from 63.2 to 77.5% (P = 0.002) without significantly increasing the colposcopy per HSIL+ detection ratio (7.7 to 8.1, P = 0.66). Conclusions HPV genotyping played an important role in managing HPV-positive women with normal cytology. Genotyping for HPV31/33 should be added to the previously recommended HPV16/18 genotyping in triaging HPV-positive women in northeastern China.

Distribution of High-Risk Human Papillomavirus Genotypes and Multiple Infections in Preneoplastic and Neoplastic Cervical Lesions of Unvaccinated Women: A Cross-sectional Study. J Low Genit Tract Dis 2020; 23:259-264. [PMID: 31592973 DOI: 10.1097/lgt.0000000000000487] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/26/2022]
Abstract
OBJECTIVE The aim of the study was to investigate the distribution of high-risk (HR) human papillomavirus (HPV) genotypes and the role of multiple infection in preneoplastic and neoplastic cervical lesions, according to histology, age, and the number of genotypes per infection. MATERIALS AND METHODS Nine hundred eighty-eight women affected by known HPV-related cervical lesions and attending the European Institute of Oncology, Milan, Italy, from December 2006 to December 2014, were selected for a cross-sectional study. Prevalence of HPV genotypes was calculated by histology and the number of genotypes per infection. Univariate and multivariable cervical intraepithelial neoplasia (CIN) 2-3 versus CIN 1 risks were estimated by logistic regression models. RESULTS Overall, HPV 16 (53.1%), HPV 31 (15.1%), and HPV 58 (6.4%) were the most frequent genotypes in precancerous lesions. At multivariable analysis, HPV 16 (p = .02), 18 (p = .013), and 56 (p = .01) were significantly associated to worsen histology, whereas HPV 39 (p = .03) and 45 (p = .03) were statistically correlated only to the increasing number of genotypes per infections. Human papillomavirus 33 was the only genotype significantly related to both the number of genotypes per infection (p = .005) and age (p = .03). Infections by HR-HPV (odds ratio [OR] = 9.48, 95% CI = 3.77-23.8, p < .001), HPV genotypes covered by current vaccines (OR = 6.28, 95% CI = 4.05-9.75, p < .001), single HPV genotype (OR = 8.13, 95% CI = 4.12-16.0, p < .001), as well as age (OR = 1.13, 95% CI = 1.07-1.19, p < .001) were significantly associated to higher risk of CIN 2-3. CONCLUSIONS The most of CIN 2+ lesions are sustained by HR-HPV genotypes, especially the ones covered by 9-valent vaccine; therefore, the widespread use of prophylactic HPV vaccines could significantly reduce the incidence of preneoplastic and neoplastic cervical lesions.

Abstract
Context Human papillomavirus (HPV) infection is the main cause of cervical cancer, but the risk is associated with the various HPV genotypes which may be found in women with or without clinical findings. Aims We aimed to identify HPV prevalence and genotype distribution in women with or without cervical lesions admitted to Gynaecology and Obstetrics Clinics of one of the largest private hospitals in Istanbul between 2013 and 2017. Subjects and Methods In the present study, cervical cytobrush samples collected from 2464 women with different cytological conditions, and investigated for the presence of HPV, and the different genotypes. Results were evaluated based on the HPV positivity in different cytological findings, and ages. Furthermore, distribution of high-risk (HR) and low-risk (LR) genotypes in different groups was investigated. Results Among all participants, 1925 (78.1%) was with the normal cytological condition, 354 (14.4%) with ASC-US; 151 (6.1%) with low-grade squamous intraepithelial lesion (LSIL), and 34 (1.4%) with high-grade squamous intraepithelial lesion (HSIL). Our results showed that 649 out of 2464 patients (26.3%) were positive, and 1815 (73.7%) were negative for the presence of HPV. Among 649 positive patients, 223 (34.3%) were found positive for more than one genotype. HPV 16 was found the most common HR-HPV type in ASC-US and LSIL whereas HPV 18 was the most common in HSIL. HPV 6 was found the most common LR-HPV type in ASC-US and LSIL whereas HPV 11 was the most common in HSIL. 26.9% of women <50 years old, and 22.3% of women ≥50 years old was positive for HPV. The most common HR-HPV genotype was 16 in both groups with (19%) or without (17%) abnormal cytology. Conclusions We concluded that HPV prevalence and genotype distribution in women with or without clinical findings is an important predictor of cervical cancer.

Abstract
Immunomics tools and databases play an important role in the designing of prophylactic or therapeutic vaccines against pathogenic bacteria and viruses. Therefore, we aimed to illustrate the different immunological databases and web servers used to design a chimeric vaccine candidate against human cervix papilloma. Initially, cellular immunity inducing major histocompatibility complex class I and II epitopes from L2 protein of papilloma 58 strain were predicted using the IEDB, NetMHC, and Tepi tools. Then, the overlapped segments from the above analysis were used to calculate efficiency on interferon-gamma and humoral immunity production. In addition, the allergenicity, antigenicity, cross-reactivity with human proteomes, and epitope conservancy of elite segments were determined. The chimeric vaccine candidate (SGD58) was constructed with two different overlapped peptide segments (23–36) and (29–42), adjuvants (flagellin and RS09), two Th epitopes, and amino acid linkers. The results of homology modeling demonstrated that SGD58 have 88.6% of favored regions based on Ramachandran plot. Protein–protein docking with Swarm Dock reveals SGD58 with receptor complex have −54.74 kcal/mol of binding energy with more than 20 interacting residues. Docked complex are stable in 100ns of molecular dynamic simulation. Further, coding sequences of SGD58 also show elevated gene expression in E. coli. In conclusion, SGD58 may prompt vaccine against cervix papilloma. This study provides insight of vaccine design against different pathogenic microbes as well.

Abstract
The human papillomavirus (HPV) 58 is considered to be the second most predominant genotype in cervical cancer incidents in China. HPV type-restriction, non-targeted delivery, and the highcost of existing vaccines necessitate continuing research on the HPV vaccine. We aimed to explore the papillomaviral proteome in order to identify potential candidates for a chimeric vaccine against cervix papilloma using computational immunology and structural vaccinology approaches. Two overlapped epitope segments (23⁻36) and (29⁻42) from the N-terminal region of the HPV58 minor capsid protein L2 are selected as capable of inducing both cellular and humoral immunity. In total, 318 amino acid lengths of the vaccine construct SGD58 contain adjuvants (Flagellin and RS09), two Th epitopes, and linkers. SGD58 is a stable protein that is soluble, antigenic, and non-allergenic. Homology modeling and the structural refinement of the best models of SGD58 and TLR5 found 96.8% and 93.9% favored regions in Rampage, respectively. The docking results demonstrated a HADDOCK score of -62.5 ± 7.6, the binding energy (-30 kcal/mol) and 44 interacting amino acid residues between SGD58-TLR5 complex. The docked complex are stable in 100 ns of simulation. The coding sequences of SGD58 also show elevated gene expression in Escherichia coli with 1.0 codon adaptation index and 59.92% glycine-cysteine content. We conclude that SGD58 may prompt the creation a vaccine against cervix papilloma.

Abstract
Background Human papillomavirus (HPV) is associated with an increased risk of cervical cancer. Using a vaccine to prevent HPV infections could be a cost-effective strategy to decrease the incidence of cervical cancer. Learning about the characteristics of CIN patients with HPV infection in Wenzhou is a key step in guiding the use of HPV vaccines and screening for cervical cancer. Methods We undertook a retrospective analysis including 2612 women who were treated in the Department of Gynecology and Obstetrics from Jan 2016 to Nov 2017. All of the patients were examined by HPV testing and histology. Results The prevalence of HR-HPV among women with cervical intraepithelial lesions aged 65-69 years (38.8%) was significantly higher than that of the other age groups. The percentage of patients diagnosed with HPV-positive HSIL progressively increased with age to a maximum of 18.0% in the group of 40 to 44 years of age. HPV 16, 52, and 58 were the three most dominant genotypes among these women, and single infections (950, 73.3%) were more common than multiple infections (346, 26.7%). Compared to cervicitis, the odds ratios (ORs) for LSIL associated with HPV 33, 52, 16 and HPV 58 infection were 5.98, 3.91, 3.65, 3.65, and 3.188, respectively; for HSIL associated with HPV 16, 33, 58 and HPV 31 were 9.30, 7.68, 5.97, and 4.21, respectively. In LSIL, the frequencies of HR-HPV 52,16,58,18 were 19.3,18.2,10.9, and 7.8%, respectively. Conclusion Our study provides important data about the HPV genotype distribution and its correlation with cervical intraepithelial lesions in the Wenzhou population.

Abstract
We assessed the prevalence characteristics of single and multiple high-risk human papillomavirus (HR-HPV) infections. A total of 1783 women who underwent colposcopy and cervical biopsy for abnormal ThinPrep Cytology Test and/or HR-HPV subtype genotyping results were enrolled in the study. Among the participants, 770 were diagnosed with cervicitis, 395 with cervical intraepithelial neoplasia grade 1 (CIN1), 542 with CIN2-3, and 76 with squamous cell carcinoma (SCC), with HR-HPV infection rates of 75.8%, 85.8%, 95.9%, and 88.4%, respectively. The prevalence of total and multiple HR-HPV infections exhibited a bimodal age distribution with a peak at ≤25 years, a decline with age and a second peak at ≥55 years, whereas single HR-HPV infections exhibited one peak from 35 to 44 years. The four most dominant HPV genotypes were HPV 16 (29.5%), 52 (15.0%), 58 (14.2%), and 18 (10.4%). In total, 67.0%, 70.4%, and 82.1% of patients with CIN1, CIN2-3, and SCC, respectively, had a single HR-HPV infection, which increased significantly with the aggravation of the cervical lesion grade (P = 0.045). Patients with a single HPV 16 infection had higher incidences of CIN2+ (62.2%) than those with multiple HPV 16 infections (52.4%) (P = 0.021). Patients coinfected with HPV 16 had higher CIN2+ incidence than those with single HPV 52, 31, 33, 35, 39, 45, 51, 56, or 59 infections (P < 0.001). This study provided baseline data on the prevalence characteristics of single and multiple HR-HPV infections in women attending a gynecological outpatient clinic in Beijing.

Abstract
To add the growing literature on baseline of high-risk human papillomavirus (HR-HPV) genotype distribution in cervical intraepithelial neoplasia (CIN) before the widespread using of HPV vaccines in Chinese mainland and to improve risk stratification of HR-HPV-positive women. Retrospectively, the data of age, cervical HPV genotypes, cytology, and pathology were collected from 1166 patients who received loop electrosurgical excision procedure (LEEP). HPV genotypes were analyzed with Flowcytometry Fluorescence Hybridization Method. And then HPV prevalence, HR-HPV genotype distribution and the correlation of HR-HPV genotypes with CIN2+ (CIN2 or severer) were analyzed. The role of multiple HR-HPV types infection with or without HPV16/18 in the pathogenesis of CIN2+ was also analyzed. The 6 most common HR-HPV genotypes were HPV16, 58, 52, 33, 18, and 31 in descending order. Compared to HR-HPV-negative women, HPV16, 33 or 58 positive women had higher risk of CIN2+ (OR = 5.10, 95% CI = 2.68-9.70; OR = 3.09, 95% CI = 1.39-6.84; OR = 3.57, 95% CI = 1.85-6.89, respectively). And women who were infected by multiple HR-HPV types infection with HPV16/18 also had higher risk of CIN2+ (OR = 2.58, 95% CI = 1.35-4.92). However, multiple HR-HPV types infection without HPV16/18 did not increase the risk significantly (P = .08). Compare to bivalent Cervarix® and quadrivalent Gardasil® , HPV prophylactic vaccine targeting HPV31, 33, 52, and 58 might provide women more protection from HPV-induced cervical cancer in China. The women who infected by HPV16, 33, 58, or multiple HR-HPV types with HPV16/18 have higher risk of CIN2+ and need to be paid more attention in screening processes. And the role of multiple HR-HPV types infection without HPV16/18 needs be further identified in more studies.
