CER818: A Highly Specific and Sensitive HPV L1 High‐Risk Serological Lateral Flow Rapid Test for Early Detection of Cervical Cancer and Its Precursor Lesions

Objective: The objective of the study is to validate a new human papillomavirus (HPV) L1 high‐risk specific serological assay in a case‐control study.Methods: Serum samples of 138 patients (cervical intraepithelial neoplasia (CIN) 1, 2, and 3 and cervical cancer), 21 vaccinees, and 246 female controls were tested for the presence of HPV L1 high‐risk specific antibodies.Results: HPV L1 high‐risk antibodies were detected in 100% of the CIN1 and 2, 86.6% of the CIN3 and 82.4% of the cervical cancer cases, 100% of the vaccinees, and 3.9% of the female controls. Area under the curve (AUC) was calculated with 0.91 for controls versus CIN2+, 0.923 for controls versus CIN1+, and 0.968 for controls versus CIN1/2.Conclusion: The HPV L1 high‐risk specific serological lateral flow rapid test shows promising data in the field of early detection of HPV high‐risk induced cervical cancer and its precursor lesions. This easy‐to‐use, robust, and affordable approach could offer a chance to reach women in low‐ or middle‐income countries (LMICs) that could not be reached by HPV molecular testing–based cervical cancer screening programs.

Determinants of Cervical Cancer Screening among Female Health Professionals in Harar Town, Eastern Ethiopia: A Cross‐Sectional Study

Background. Early screening for cervical cancer is a key life‐saving intervention in reducing maternal mortality and morbidity. Despite the high burden of cervical cancer, the coverage of cervical cancer screening is low in developing countries, including Ethiopia. There is a paucity of information on the utilization of cervical cancer screening among female health professionals in eastern Ethiopia. This study aimedto assess the determinants of cervical cancer screening among female health professionals in Harar town, eastern Ethiopia. Method. An institution‐based cross‐sectional study was conducted among 232 female health professionals in Harar town from September 01 to 30, 2022. Data were entered using EpiData version 3.1 and analyzed using SPSS version 27.0. Multivariable logistic regression analyses were conducted to identify significant factors for the level of cervical cancer screening. An adjusted odds ratio (AOR) with a 95% confidence interval was used to report the strength of association and statistical significance declared at p value < 0.05. Results. The prevalence of cervical cancer screening among female health professionals was 16.8% (95% CI: 11%, 22%). Higher education level (AOR = 4.28, 95% CI: 1.68, 10.90), use of contraceptives (AOR = 2.71, 95% CI: 1.17, 6.23), training on cervical cancer screening (AOR = 2.53, 95% CI: 1.05, 6.08), good knowledge about cervical cancer screening (AOR = 3.37, 95% CI: 1.44, 7.91), and positive attitude toward cervical cancer screening (AOR = 5.31, 95% CI: 2.04, 13.83) were independent factors that increased the utilization of cervical cancer screening. Conclusion. One in every six female health professionals was screened for cervical cancer. Education level, contraceptive use, cervical cancer screening training, cervical cancer screening knowledge, and attitude toward cervical cancer screening were the determinants of cervical cancer screening utilization among female health professionals. Improving the health professionals’ knowledge and attitude toward cervical cancer screening through upgrading their education level and training on cervical cancer screening would be essential to improving the level of cervical cancer screening.

Acceptance of Human Papillomavirus Vaccination and Associated Factors among Girls in Arba Minch Town, Southern Ethiopia, 2020

Background. Cervical cancer is Ethiopia’s second biggest cause of cancer-related death among women. The introduction of human papilloma virus (HPV) vaccination is expected to have a significant impact on the burden of cervical cancer. In Ethiopia, particularly in our study area, little is known regarding girls’ acceptance of HPV vaccination. Therefore, this study has assessed the acceptance of HPV vaccination and associated factors among girls in Arba Minch town, southern Ethiopia. Methods. A school-based cross-sectional study was conducted on January 1, 2020. Based on convenience, Arba Minch town was purposefully selected. Stratification was done to stratify private and public schools, then simple random sampling to select sample schools from each, and finally, a proportional allocation of sample size to each school. The determinants and independent variables that influence the acceptance of the human papillomavirus vaccination were determined using a multivariable logistic regression model. Results. This study’s overall acceptance rate for study participants was 50.4% (95% CI) (45.9–55.2). Girls’ age ( AOR = 2.93 , 95% CI (1.57_5.47), P value 0.001), mothers’ educational level (secondary and more than secondary, AOR = 2.40 , 95% CI (1.01_5.73), P value 0.048, and 3.64, 95% CI (1.61_8.25), P value 0.002, respectively), positive attitude ( AOR = 5.22 , 95% CI (2.96_9.19), P value ≤ 0.001 ), good knowledge ( AOR = 2.49 , 95% CI (1.19_5.24), P value 0.001), and receiving childhood immunization ( AOR = 14.85 , 95% CI (8.58_25.72), P value ≤ 0.001 ) were factors associated with girls’ acceptance of the human papillomavirus vaccination. Conclusions and Recommendation. Only half of the study participants accepted HPV vaccination. Therefore, Arba Minch town health institutions should better boost the acceptance of HPV vaccination by improving the knowledge and attitudes of girls. Factors associated with girls’ acceptance of HPV vaccination were age, mothers’ educational status, positive attitude, knowledge of HPV vaccination, and receiving childhood immunization.

BV associated bacteria specifically BVAB 1 and BVAB 3 as biomarkers for HPV risk and progression of cervical neoplasia

Background. Bacterial vaginosis (BV) is associated with high-risk HPV (hrHPV) genotypes. There is a proposed bidirectional relationship between hrHPV and vaginal microbial diversity. This study investigated the association between BV associated bacteria in women co-infected with Human immunodeficiency virus (HIV) and hrHPV. Methods. Stored cervical cytobrush samples were used for real time PCR detection of eight BV associated bacteria. Analysis of BV bacteria detected against HPV infection, socio-demographics and HIV data were conducted in R Statistical computing software of the R Core Team, 2020, version 3.6.3. Results. A total of 190 samples were analysed. A. vaginae (p <0.001) BVAB 1 (p <0.001), BVAB 2 (p =0.428), BVAB 3 (p <0.001), Lactobacillus species (p =0.016) and S. sanguinegens (p =0.007) were associated with prevalent hrHPV. Increasing CIN severity was independently associated with detection of BVAB 1 OR 1.51(95% CI: 0.42-5.55), BVAB 3 OR 2.72(95% CI:0.90-8.55) and S. sanguinegens OR 1.02(95% CI:0.37-2.80). All HPV genotypes/groups, gravida <2, A. vaginae (p =0.002) and BVAB 1 (p =0.026) were significantly associated with HPV persistence. BVAB 3, p =0.010 and HPV 16 were significantly associated with HPV reinfection. Conclusion. There is a significant association of A. vaginae, BVAB 1, BVAB 3, S. sanguinegens and Lactobacillus spp to prevalent hrHPV. BVAB 1, BVAB 3 and S. sanguinegens had an increased odds for increasing CIN severity. A vaginae, BVAB 1, gravida and all the HPV genotypes/groups were significantly associated with HPV persistence. Only BVAB 3 and HPV 16 were significantly associated with hrHPV reinfection at 1 year review. BVAB 1 and BVAB 3 are possible biomarkers for HPV infection and CIN progression.

Burden and Associated Genotype Patterns of High-Risk Human Papilloma Virus Infection and Cervical Cytology Abnormalities among Women in Central India

Background. The epidemiology of human papilloma virus (HPV) infection and the pattern of HPV genotype distribution are much-needed parameters to assess the risk of cervical cancer among females. However, due to less availability of data on HPV burden and its genotypes from various geographical regions in India makes cervical cancer screening modalities and vaccination strategies difficult to implement. Objective. The present study was conducted to identify the various genotypes particularly high-risk HPV types in premalignant or malignant cervical lesions. Methods. The study was a hospital-based cross-sectional study wherein 295 symptomatic women were screened by Pap smear and multiplex real-time PCR was performed for HPV genotypes identification in women with abnormal cervical cytology. Results. Out of 295 women, 237 (80.3%), 45 (15.3%), and 13 (4.4%) women had normal Pap smear, squamous cell carcinoma and precancerous cytology, respectively. Among these 58 women having abnormal cervical cytology, HPV was detected in 48 (81.0%) participants. Most common HPV genotypes in our study were HPV 16 ( n = 29 ; 60.4%) followed by mixed infections; i.e., more than one type of HPV was detected ( n = 10 , 20.8%). HPV 18 was detected only in 6.25%, whereas other high-risk HPV genotypes were found to be 12.5%. Conclusion. HPV positivity was >80% in women having abnormal Pap smear. The prevalence of HPV 18 was found to be much less in Central India, compared to other parts of country. HPV 16 was the most common genotype followed by mixed HPV genotype infections. It is evident from our study that symptomatic women even if having normal Pap smear should be screened for HPV and followed up with periodic Pap smears for detecting any change in cervical cytology, thus preventing cervical cancer in women.
