Anyplex™II HPV28 is a new PCR assay designed for HPV genotyping. It can detect 28 HPV types including 19 high-risk and 9 low-risk types. This study evaluated the performance of Anyplex™II HPV28 on 123 fresh cervical samples screened in parallel with HPV Sign® Genotyping Test. Of the 123 samples screened, 93 were positive, 15 negative, and 15 discordant. The total number of HPV positive samples combined was 108: 38 single infections and 70 multiple infections. The agreement between the two tests was 87.8%, κ=0.592. Genotype specific agreement was strong for HPV 16 (k=0.761), HPV 18 (k=0.674), and HPV 35 (k=0.796). Sensitivity and specificity of Anyplex™II HPV28 assay using HPV Sign® Genotyping Test as reference was 84.8% and 94%; conversely, sensitivity and specificity of HPV Sign® Genotyping Test was 29% and 99.5%. Anyplex™II HPV28 assay is a sensitive and specific assay suitable for HPV genotyping but requires clinical validation.

Optimization and analytical validation of the Allplex HPV28 genotyping assay for use in first-void urine samples.

Despite first-void urine (FVU) being increasingly recognized as a credible specimen for human papillomavirus (HPV) detection, there is a lack of well-validated testing methods providing full quantitative genotyping required for vaccine impact monitoring from FVU samples. The Allplex HPV28 assay, capable of individually detecting 28 HPV genotypes, presents a promising method. We aimed to evaluate its genotype-specific performance on FVU samples, following optimization of FVU preanalytics.

Background: Self-sampling is now a key component within HPV-based cervical screening programmes to engage individuals and enhance participation. As self-sampling is relatively new, information on the influence of pre-analytical parameters such as transit-temperature and time between sampling and testing on HPV test results requires detailed investigation.
Methods: FLOQSwabs® and Evalyn Brushes® were used to assess HPV and cellular stability over a 30-week period (0w,4w,12w,30w) at 4 °C, ambient, and 37 °C.

Article Synopsis
- - This study examined the prevalence and characteristics of cervical HPV among 325 women (ages 18-60) visiting a community health facility in Eastern Cape, South Africa, revealing an overall HPV prevalence of 65.2%, with the highest rates in younger women (80.9% in ages 18-25).
- - HPV infection rates showed a decline with age, particularly for high-risk HPV (HR-HPV) among all women and low-risk HPV (LR-HPV) among HIV-negative participants, but not among HIV-positive women.
- - A notable percentage of participants were infected with HPV types included in the Cervarix and Gardasil vaccines, highlighting a significant burden of HPV and suggesting the need for enhanced

Article Synopsis
- A study was conducted in Thailand to compare the effectiveness of single-dose versus two-dose regimens of the HPV vaccine among 13-14 year old schoolgirls.
- The researchers assessed HPV prevalence among unvaccinated schoolgirls and compared it to vaccinated girls over a period of four years.
- Results showed a significant reduction in HPV prevalence among vaccinated girls, highlighting the potential effectiveness of a single-dose regimen.

Article Synopsis
- In 2014, South Africa launched an HPV vaccination program for girls aged 9 and older, but this study focused on 17-18 year old girls who weren't vaccinated, assessing HPV prevalence and related risk factors.
- From June to December 2019, the study surveyed adolescents at primary care clinics and collected data on HPV testing, HIV status, and sexual history from 900 participants, with a focus on understanding the link between these factors and HPV detection.
- Results showed that 56.5% had high-risk HPV, with a higher prevalence in those living with HIV, underscoring the need for increased HPV vaccination efforts in populations with high HIV rates.
