Abstract Background: The significance of HPV viral load in the detection of cervical lesions is still controversial. This study analyzed the correlation between the high-risk (HR)-HPV viral load and different cervical lesion degrees.Methods: This was a retrospective study of the patients who first visited the hospital between January 2015 and June 2018. Patients with positive HR-HPV were screening for cervical cancer. The HR-HPV DNA load was measured by the second generation hybrid capture (HC2) technology. The patients grouped as normal, CIN I, CIN II, CIN III, and cervical cancer. Multivariable logistic regression was performed to explore the association between HR-HPV DNA load and cervical lesions.Results: Finally, 265 patients were grouped as normal (n=125), CIN I (n=51), CIN II (n=23), CIN III (n=46), and cervical cancer (n=20). Among them, 139 (52.5%) had a low viral load, 90 (34.0) had a moderate viral load, and 36 (13.4%) had a high viral load. Taking the normal control group as a reference, a high viral load was an independent factor for CIN I (CIN I: OR=3.959, 95%CI: 1.300-12.059, P=0.015) CIN II (OR=6.211, 95%CI: 1.641-23.513, P=0.007), CIN III (OR=7.002, 95%CI: 2.308-21.244, P=0.001), and cervical cancer (OR=9.439, 95%CI: 2.394-37.22, P=0.001).Conclusion: Cervical lesions are closely related to HR-HPV infection. Higher HR-HPV viral load in cervical lesions was associated with a higher risk of high-grade cervical lesions.

Abstract Background The significance of HPV viral load in the detection of cervical lesions is still controversial. This study analyzed the correlation between the high-risk HPV viral load and different cervical lesion degrees. Methods This retrospective study included women positive for high-risk HPV DNA and screened for cervical lesions between 01/2015 and 06/2018. The high-risk HPV DNA load was measured by the second-generation Hybrid Capture technology and classified as low, moderate, and high. Colposcopy and biopsy were performed in all patients. The patients were grouped as normal, cervical intraepithelial neoplasia (CIN) grade 1, CIN grade 2, CIN grade 3, and cervical cancer. Multivariable logistic regression was performed to explore the association between high-risk HPV DNA load and cervical lesions. The odds ratios (ORs) represent the odds for increasing from low to high viral load. Results Finally, 265 patients were grouped as normal (n = 125), CIN 1 (n = 51), CIN 2 (n = 23), CIN 3 (n = 46), and cervical cancer (n = 20). Among them, 139 (52.5%) had a low viral load, 90 (34.0) had a moderate viral load, and 36 (13.4%) had a high viral load. Taking the normal control group as a reference, a high viral load was an independent factor for CIN 1 (OR = 3.568, 95% CI: 1.164–10.941, P = 0.026), CIN 2 (OR = 6.939, 95% CI: 1.793–26.852, P = 0.005), CIN 3 (OR = 7.052, 95% CI: 2.304–21.586, P = 0.001), and cervical cancer (OR = 8.266, 95% CI: 2.120–32.233, P = 0.002). Conclusions Among women who underwent cervical biopsy, higher high-risk HPV viral load in cervical lesions was associated with a higher risk of high-grade cervical lesions.

Hpv Viral Load

Human papillomavirus (HPV) high risk genotype infection and HPV viral load influences the development of invasive cervical cancer and cervical intra-epithelial neoplasia (CIN). HPV DNA testing for screening of cervical cancers may play a potential role in its early detection and management. The present study detected HPV DNA and estimated HPV viral load in different types of cervical lesions among Bangladeshi women. Using the Hybrid Capture 2 (HC2) assay, HPV DNA was tested among 68 women between 25-70 years of age. A total of 13 (19.1%) cases were positive for HPV DNA. The highest viral load (501 x 10³ copies/ml) was detected in a patient with invasive carcinoma, while the lowest viral load (105 x 10³ copies/ml) was detected from a case of chronic cervicitis. The mean viral load in CIN I was 119.25 x 10³±12.5 x 10³ copies/ml (range: 110 x 10³ - 137 x 10³) and 208.50 x 10³ ± 0.59 x 10³ copies/ml (range: 139 x 10³-305 x 10³) in CIN II / III. Interestingly, HPV DNA was detected from a patient with normal cytological findings. Our study observed a moderate presence of high-risk HPV genotypes among women with cervical lesions. The HPV viral load varied with the age of the patients and stage of cervical lesions. The HC2 assay is a promising tool for diagnosing high-risk HPV infection especially before cytology tests show any abnormality.

Abstract Background To investigate distributions of cervical lesions and factors associated with the severity of the cervical lesions in high-risk HPV (hr-HPV) positive women with atypical squamous cells of undetermined significance (ASC-US) cytology. Methods Clinical information of 250,000 women who underwent HPV and cytological test was collected from January 2012 to January 2019. The association between the severity of the cervical lesions and hr-HPV genotypes, hr-HPV viral load, and ages, were analyzed in hr-HPV-positive/ASC-US women. Results 3459 hr-HPV-positive/ASC-US women were enrolled in this study. Overall, 43.51% of women with ASC-US had normal histological results, 34.35% had high-grade squamous intraepithelial lesion (HSIL), and 1.30% had cervical cancer. The rate of HSIL or worse (HSIL+) in women with single HPV16 infection (63.09%) was the highest, followed by HPV33 (57.50%), HPV51 (36.11%), HPV58 (36.11%), HPV52 (28.28%), HPV18 (26.37%), HPV66 (19.35%), HPV39 (18.92%), HPV53 (15.00%), and HPV56 (8.51%). Detection rate of HSIL+ in low, intermediate and high viral-load groups were 15.87% (n = 30), 34.91% (n = 74) and 40.68% (n = 214) (Cochran-Armitage Trend test χ2 = 35.03, p < 0.0001). Compared with the 51–60-year-old group (21.65%), the women in ≤ 30 (40.52%), 31–40 (39.67%), and 41–50 (34.22%) year-old groups had significantly higher risk of HSIL+. The women in ≤ 51–60 (2.68%) and > 60 (3.41%) year-old groups were at increased risk for cervical cancer, compared with the ≤ 30-year-old group (0.61%). Conclusions ASC-US women with HPV 16/18/33/51/52/58 single infection and multiple infections, as well as high HPV viral loads, have high risk of HSIL+.

AbstractCervical cancer morbidity and mortality in Lithuania is one of the biggest in the European Union. The main risk factor of cervical cancer is human papillomavirus (HPV). The deletion of the HPV E2 gene influences HPV DNA integration into the cell genome, as well as a rapid progression of cervical lesions. The purpose of this study is to determine HPV, its types, and HPV 16 integration in different grades of cervical intraepithelial neoplasias (CIN). 253 women with cytological lesions were involved in the study. After a histology, 31 women were diagnosed with CIN I, 35 with CIN II, and 51 with CIN III. The biggest prevalence of HPV infection was detected in women younger than 25 years old (69.7%) and in women with CIN II (90.9%). HPV 16 was detected in 67.8% of all cases, with the highest prevalence in CIN III (84.4%). A partial integration form was detected in 65.0% of HPV 16 infected women, a complete virus integration in 26.5%, and an episomal form in 8.4% of cases. Our study concludes that in all the cases confirmed using a histology, the partial virus integration form of CIN was identified the most. It was less frequently detected in CIN I cases (60.0%), but more frequently in CIN II and CIN III cases (72.8 and 69.3%, respectively).

Abstract Background: High-risk human papillomavirus (HR-HPV) load is thought to be influenced by many factors, and relationship between viral load and degree of cervical lesion is controversial. This study was to explore possible influencing factors of HR-HPV viral load in uterine cervix.Methods: 605 women who needed colposcopic evaluation for abnormal cervical screening in Affiliated Hospital of Weifang Medical University, China, between November 2017 and September 2018 were enrolled. Cervical specimens were collected from endo- and ectocervix separately using two different cervical brushes. Hybrid Capture II test was used to measure HR-HPV load. Age, histological severity, number of viral types, area and location of cervical lesions were recorded. The correlation between viral load and influencing factors was analysed using univariate and multivariate analysis.Results: HR-HPV load was positively correlated with age, histological severity, multiple HPV types and area of cervical lesions (P<0.05). Viral load with combination of endo- and ectocervical sampling was significantly higher than simple endocervical sampling (P<0.001). Multivariate analysis showed that age, multiple HPV types and area of cervical lesions were independent factors for HR-HPV load with combination of endo- and ectocervical sampling (P<0.05). However, only age and area of cervical lesions were independent factors for viral load with simple endocervical sampling (P<0.05). No significant association was found between viral load and lesion severity in multivariate analysis (P>0.05).Conclusion: HR-HPV load is influenced by age, histological severity, multiple viral types, area of cervical lesion and sampling methods. Age and area of cervical lesions are independent factors for viral load.

Abstract Objectives To evaluate the correlation between tumor-infiltrating lymphocytes (TILs) and the viral load of high-risk human papillomavirus (HR-HPV) in cervical cancer patients. Methods A total of 62 cervical cancer patients were recruited during 1993-1994 and assigned into four groups treated with radiotherapy alone or radiotherapy combined with chemotherapy and/or thermotherapy. Ki67+ tumor cells, CD4+, CD8+, FoxP3+, OX40+ and granzyme B+ TILs were detected by immunohistochemistry. The viral load of HR-HPV in biopsy tissues before therapy was detected by in situ hybridization. Results The patients with high HPV viral load showed a significantly lower 15-year survival rate and an advanced International Federation of Gynecology and Obstetrics (FIGO) stage and increased recurrence rate. The distribution of Ki67+ tumor cells, FoxP3+ TILs, and CD8+/FoxP3+ ratio was obviously different between low and high HPV viral load groups. A worse clinical outcome was also implicated with increased HPV viral load tested by Cox regression analysis. Conclusions Patients with increased HR-HPV viral load tend to be resistant to therapy with decreased immune surveillance in the immune microenvironment. Thus, HR-HPV viral load would influence the local immune microenvironment, and then further affect the survival of cervical cancer patients.
