Infection with human papillomavirus (HPV) is the main cause of cervical cancer, the principal cancer in women in most developing countries. Molecular epidemiologic evidence clearly indicates that certain types of HPV are the principal cause of invasive cervical cancer and cervical intraepithelial neoplasia. Comprehensive, high-throughput typing assays for HPV, however, are not currently available. By combining L1 consensus PCR and multiplex hybridization using a Luminex xMAP system-based suspension array, the authors developed a rapid high-throughput assay, the HPV DNA suspension array (HPV-SA), capable of simultaneously typing 26 HPVs, including 18 high-risk HPV genotypes and eight low-risk HPV genotypes. The performance of the HPV-SA applied to 26 synthetic oligonucleotide targets was evaluated. The HPV-SA system perfectly discriminated 18 high-risk HPV targets from eight low-risk HPV targets. To assess the clinical applicability of the assay, the HPV-SA was performed with 133 MY09/MY11 primer set-mediated PCR (MY-PCR)-positive clinical specimens; of the 133 samples, 121 were positive by HPV-SA. Both single and multiple types were easily identified. The authors believe that improvement of the assay may be useful for epidemiological studies, cancer-screening programmes, the monitoring of therapeutic interventions, and the evaluation of the efficacy of HPV vaccine trials.

Abstract Background The causative agent of cervical cancer referred to as Human papillomavirus (HPV) remains a real public health problem. Many countries in West Africa, such as Togo have no data on the high-risk HPV (HR-HPV) infection and genotypes distribution. In order to fill the knowledge gap in the field in Togo, the main objective of this study was to determine the prevalence of pre-cancerous lesions of the cervix and HR-HPV genotypes among Togolese women. Methods Samples were collected from 240 women by introducing a swab in the cervix. Then, the screening of precancerous cervical lesions using the visual inspection with acetic acid and lugol (VIA / VIL) was conducted. The HR-HPV genotypes were characterised by real-time multiplex PCR. Results Out of 240 women recruited, 128 (53.3%) were infected by HR-HPV. The most common genotypes were HPV 56 (22.7%), followed by HPV 51 (20.3%), HPV 31 (19.5%), HPV 52 (18.8%) and HPV 35 (17.2%). The least common genotypes were HPV 33 (2.3%) and HPV 16 (2.3%). Among the women, 1.3% (3/240) were positive to VIA/VIL. Conclusion This study allowed HR-HPV genotypes to be characterised for the first time in Lomé, Togo. This will help in mapping the HR-HPV genotypes in West Africa.

Introduction: Various Human papillomavirus (HPV) types cause cervical cancer, and represent the primary cause of cancer death in Africa and the second cause of most common cancers in Cameroon. Herein, we determined the prevalence of high-risk HPV types in women and associated cervical cytologic abnormalities in Yaounde, Cameroon. Methodology: A cross-sectional study targeting HPV-positive women aged 20 and over was conducted between March and June 2020 at the Saint Martin de Porres’ Health Centre in Yaounde. HPV tests were performed by PCR for detection of HPVs 16, 18, 33, and 45. The test was performed on 616 women using exfoliated cell specimens; then, we processed on cytological diagnosis with Pap smears on HPV positive specimens. Results: The HPV types tested were detected in 137 participants, of which 38.7% with multiple HPV infections, and the remaining part with single HPV infections of type HPV 16 (28.5%), HPV 18 (17.5%), HPV 33 (10.2%), and HPV 45 (5.1%). Cervical cytologic abnormalities were found in 69.34% of participants including: LSIL (49.63%), HSIL (15.32%), ASC-US (3.66%) and AGC (0.73%). Co-infections with HPV 16 and HPV 18 were significantly associated with HSIL (p = 0.001) lesions, while HPV 45 was more common in participants with normal cytology (p = 0.001). Cervical lesion occurrence was significantly associated with the number of sexual partners (p = 0.02) and history of oral contraceptive pill use (p = 0.001). Conclusions: Our results suggest that HPV 16 and 18 are predominant in Yaounde, and are associated with more severe precancerous 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.
