Abstract Background: Human papillomavirus (HPV) infection is the main cause of precancerous lesions and cervical cancer in women. To determine the epidemiological characteristics as well as the relationship between the HPV genotype and cytology test results among women, we retrospectively collected and analyzed the data from Zhoupu District hospital in Shanghai, China.Methods: We made a retrospective analysis of human papillomavirus prevalence rate of 23,724 women between 2014 and 2019 in the District Zhoupu of Shanghai City in China. Their cervical exfoliations were collected. HPV genotype testing was performed using a commercial kit designed to detect 21 HPV subtypes including 15 high-risk HPV subtypes(16, 18, 31, 33, 35, 39, 45, 51, 52, 53, 56, 58, 59, 66 ,68) and 6 low-risk HPV subtypes(6, 11, 42, 43, 44 and 81). And the thinPrep cytological test (TCT) was also performed at the same time.Results: Among all 23,724 cases, 3,816 (16.08%) women were infected with HPV. HPV52 (3.19%), HPV58 (2.47%) and HPV16 (2.34%) had higher prevalence. 3,480(91.20%) single-type infections were more common than 336(8.8%) multiple-type infections. Single-type infection was more frequently seen in women aged 50–60 years (16.63%) and <30 years (15.37%), and multiple-type infection was more common in those aged >= 60 (2.67%). Significant differences in secular trends from 2014 to 2019 were observed for subtypes HPV52, 58 and 16.HPV positive rates of women changed significantly along with the time period from 2014 to 2019.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 squamous cells (ASC), high-grade squamous intraepithelial lesions (HSIL), low-grade squamous intraepithelial lesions (LSIL), atypical glandular cells (AGC) 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 a key step in the secondary prevention of cervical cancer. Further tracking the results of HPV and TCT was an important clinical strategy for the treatment of cervical precancerous lesions. The widespread use of preventive HPV vaccines can significantly reduce the incidence of pre-neoplastic and neoplastic cervical lesions.

Purpose. This study investigated the infection status and relationship between other common lower genital tract infectious pathogens and high-risk human papillomavirus (HR-HPV) in the high-grade cervical lesions. Methods. Overall, 882 patients were enrolled in this retrospective study, of which 339 patients (≥HSIL group) were confirmed with high-grade squamous intraepithelial lesions (HSIL) or cervical squamous cell carcinoma (SCC), while 543 patients (≤LSIL group) were diagnosed with low-grade squamous intraepithelial lesions (LSIL) or normal cervical pathology diagnosis. Cervical swab specimens were tested for HPV, pathogenic bacteria (PB), U. urealyticum (UU), M. hominis (MH), and C. trachomatis (CT) in both groups. Results. The infection rates of HR-HPV, PB, UU (at high density), and CT were higher in the ≥HSIL group than in the ≤LSIL group (P<0.001); however, higher infection rates with MH were not observed (P>0.05). PB, UU, and CT were associated with HR-HPV infection (P<0.001). The PB and UU infection rates in the ≥HSIL group were significantly different from those in the ≤LSIL group, regardless of whether there was an HR-HPV infection at the same time (P<0.05). However, this was not the case for the CT (P>0.05). Furthermore, 259 pathogenic bacterial strains were detected in 882 cases. The difference in the distribution of pathogenic bacterial flora in the different grades of cervical lesions had no statistical significance, which was prioritized over Escherichia coli (P>0.05). Conclusion. PB, UU, and CT infection is associated with susceptibility to HR-HPV, HR-HPV coinfection with these pathogens might increase the risk of high-grade cervical lesions, and PB and UU might be independent risk factors for cervical lesions.

Human papillomavirus (HPV) can induce a wide spectrum of squamous intraepithelial lesions (SIL) of varying severity. The aim of the present study was to establish the frequency of HPV infection and identify the genotypes circulating in women from Córdoba, Argentina, in relation to age and cytology. A total of 186 women, between 18 and 65 years old, with antecedents of SIL, underwent a pelvic examination and had cervical cells collected for cytology and HPV DNA detection. Ninety-six samples (51.6%) were positive for HPV detection, and sixty-three (65.6%) of them showed the presence of at least one HR-HPV. Low- and high-grade SIL showed significant association in patients younger than 35 years of age. We found 18 different genotypes, with a greater presence of HR-HPV. Genotypes 16 and 6 were the most frequent. Seven (7.3%) multiple infections, 85.7% of which had at least one HR-HPV, were detected. The detection of a large number of different HPV genotypes is a warning sign. It is thus necessary to strengthen the monitoring of the circulation of high-risk genotypes, currently less prevalent in intraepithelial lesions, as a control measure for the possible impact of the implementation of vaccines against genotypes 16 and 18.
