The burden of hospitalization due to HPV infections in Tuscany, Central Italy

The Burden of HPV-Related Hospitalizations: Analysis of Hospital Discharge Records from the Years 2015-2021 from a Southern Italian Region

(1) Background: The human papillomavirus (HPV) is the most common agent related to sexually transmitted infections in the general population. Its genotypes are classified into two main classes, high-risk genotypes and low-risk genotypes, according to their capacity to induce cancers. The low-risk class (types 6 and 11) is associated with anogenital and genital lesions. The high-risk class is responsible for up to 4.5% of all new cancer cases yearly. The aim of this study was to evaluate the incidence of HPV-related hospitalizations and its trend in a southern Italian region for the years 2015-2021. (2) Methods: This was a retrospective study performed in the Abruzzo region, Italy. All admissions for the period 2015-2021 were extracted from the hospital discharge record (HDR). (3) Results: During the study period (2015-2021), a total of 5492 hospitalizations attributable to HPV infection occurred in the Abruzzo region, Italy. A significant number of admissions were related to cervical cancer (3386 cases) and genital warts (638 cases). The trend declined for all diagnoses except for penile cancer admissions. Considering the first year of the pandemic (year 2020), a decrease in the standardized incidence of the majority of the diseases considered was reported, particularly among cases of cervical cancer. (4) Conclusions: HPV-related hospitalizations decreased in Abruzzo during study period. These results could be useful to LHAs and policy-makers in improving vaccination coverage and screening adherence.

Evaluation of the Burden of HPV-Related Hospitalizations as a Useful Tool to Increase Awareness: 2007-2017 Data from the Sicilian Hospital Discharge Records

In light of the implementation of human papillomavirus (HPV) prevention strategies, epidemiological studies in different geographical areas are required in order to assess the impact of HPV-related diseases. The purpose of the present study was to describe the burden of HPV-related hospitalizations in Sicily. A retrospective observational study estimated 43,531 hospitalizations attributable to HPV from 2007 to 2017. During the observed period, there was a decrease for all HPV-related conditions with a higher reduction, among neoplasms, for cervical cancer (annual percent change (APC) = −9.9%, p < 0.001). The median age for cervical cancer was 45 years old, with an increasing value from 43 to 47 years (p < 0.001). The age classes with greater decreases in hospital admissions for invasive cancers were women aged 35 years or more (APC range from −5.5 to −9.86) and 25–34 years old (APC = −11.87, p < 0.001) for women with cervical carcinoma in situ. After ten years for vaccine introduction and sixteen years for cervical cancer screening availability, a relatively large decrease in hospital admissions for cervical cancer and other HPV-related diseases in Sicily was observed. Some clinical characteristics of hospitalization, such as increasing age, are suggestive clues for the impact of preventive strategies, but further research is needed to confirm this relationship.
