Special Issue Information

Dear Colleagues,

Human papillomavirus (HPV) is an important sexually transmitted infectious agent that is associated with various types of cancer. In women, HPV infection is mainly related to the development of cervical lesions, which can progress to cervical cancer.

HPV belongs to the Papillomaviridae family, which is formed by more than 200 viral genotypes. Among them are structural differences that allow the epidemiological classification into high risk, probable high risk and low risk for developing cancer. Therefore, understanding the epidemiology of HPV infection and the distribution of HPV genotypes is relevant for assessing cervical cancer risk in women.

In addition, studies have observed the potential for oncological risk among variants of high-risk HPV types, based on the clinical analysis of patients associated with molecular diagnosis. The variants have shown a set of polymorphisms that point to distinct risks for the development of high-risk lesions and cancer, since different variant strains can present different oncogenic potentials, especially when taking into account the different geographic origins and evolutionary modifications of the virus and the host, creating a different clinical profile among populations.

We welcome submissions of research and review articles on any relevant topics that involve the epidemiological aspects of HPV infection, HPV infection control, and the genetic diversity of high-risk HPV types and their respective oncogenic potentials.

Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Tropical Medicine and Infectious Disease is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs).

Human papillomavirus (HPV) genotype distribution varies according to the assessment method and the population targeted. This study aimed to assess HPV infection prevalence in women aged 23 to 82 with abnormal cytology attending King Fahad Medical City (KFMC), Riyadh, Saudi Arabia, using retrospective data collected from January 2021 to December 2022. Cytological distribution included 155 samples of atypical squamous cells of undetermined significance (ASCUS) (n = 83), low-grade squamous intraepithelial lesion (LSIL) (n = 46), high-grade squamous intraepithelial lesion (HSIL) (n = 14), atypical squamous cells cannot exclude high-grade squamous intraepithelial lesion (ASC-H) (n = 10), and squamous cell carcinoma (SCC) (n = 2). All samples were submitted to HPV detection and genotyping using Xpert HPV assay specimens. The most prevalent epithelial abnormalities were ASCUS (53.50%). Positive HPV infection results were observed in 52.9% of the samples. The highest prevalence of HPV genotypes, accounting for 31%, was attributed to the other high-risk genotypes, including 31, 33, 35, 39, 51, 52, 56, 58, 59, 66, and 68, followed by high-risk genotype 16, which counted in 11.60% of cases. Individuals who tested positive for HPV 16 were at a high risk of ASC-H, HSIL, and LSIL. Those testing positive for HPV 18–45 exhibited an elevated risk of LSIL, and those with positive results for other high-risk HPV genotypes were at an increased risk of ASCUS and LSIL, suggesting a low oncogenic potential. The results suggest that the percentage of association between samples with abnormal cervical presentation and negative high-risk HPV diagnosis is noticeably increasing. This underscores the need for effective screening programs and an understanding of the impact of specific HPV genotypes on cervical abnormalities. Full article
