Sexually transmitted human papillomavirus and related sequelae

Area of Science:

• Oncology
• Virology
• Immunology

Background:

• Over 40 types of human papillomavirus (HPV) are sexually transmitted, affecting oropharyngeal and anogenital mucosa.
• High-risk HPV types are linked to precancerous and cancerous lesions in the cervix, vagina, vulva, penis, anus, and oropharynx.
• Low-risk HPV types cause benign conditions like anogenital warts, while immunodeficiency can lead to persistent infections and increased disease risk.

Purpose of the Study:

• To review the multifaceted mechanisms of HPV-induced malignant transformation.
• To highlight the efficacy of HPV vaccination in preventing infection and related sequelae.
• To emphasize the importance of early detection and treatment of precancerous lesions for secondary prevention.

Main Methods:

• Review of scientific literature on HPV infection, pathogenesis, vaccination, and screening.
• Analysis of the interactions between HPV, cellular pathways, the immune system, and the microbiome.
• Evaluation of diagnostic methods including molecular HPV testing, cytology, and tissue biopsy.

Main Results:

• HPV infection involves complex interactions with cellular pathways, the immune system, and potentially the microbiome.
• HPV vaccination is highly effective in preventing infection and associated diseases.
• Early detection strategies like HPV testing, cytology, and biopsy are crucial for managing precancerous lesions.

Conclusions:

• HPV vaccination is a primary prevention strategy against HPV-related cancers and warts.
• Secondary prevention through early detection and treatment of cervical and anal precancers remains essential.
• A comprehensive approach combining vaccination, screening, and timely treatment can avert HPV-related cancer development.
