Вирус папилломы человека (Human Papillomavirus) высокого канцерогенного риска (16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59), ДНК генотипирование [реал-тайм ПЦР]

Human papillomavirus (HPV) high‑risk genotypes, DNA genotyping by real‑time PCR, supports three principal applications: detection of oncogenic HPV infection, determination of whether a specific genotype persists over time, and risk stratification in patients with cervical epithelial abnormalities. In clinical practice, high‑risk HPV DNA testing and genotyping complement cytology to clarify management, especially when evaluating dysplasia or monitoring after treatment for cervical intraepithelial neoplasia.

Human papillomaviruses are ubiquitous epitheliotropic viruses that infect cutaneous and mucosal surfaces and include genotypes with oncogenic potential. Transmission occurs through close contact with infected epithelium, most commonly via sexual exposure; vertical transmission from an infected mother can occur. Individuals may harbor multiple HPV genotypes concurrently. Factors associated with acquisition and expression of HPV infection include early sexual debut, multiple sexual partners, immunosuppression, use of oral contraceptives, nutritional deficiencies, concurrent sexually transmitted infections, tobacco use, and residence in large urban centers. The incubation period ranges from approximately 2 months up to 2–10 years. Many infections remain subclinical, with normal findings on colposcopic, cytologic, and histologic examinations. About 30% of infections clear spontaneously within 6–12 months. Detection of latent HPV infection relies on nucleic acid amplification testing; real‑time PCR can identify viral DNA when clinical signs are absent. Acute infection may manifest with benign epithelial proliferations such as papillomas, common warts, and anogenital condylomas. In children, HPV can cause laryngeal papillomatosis. Infection of trophoblastic tissue has been associated with spontaneous abortion. Integration of HPV DNA into the host genome promotes dysplasia and neoplasia, most often arising in the cervical transformation zone. High‑risk genotypes include 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, and 68. Real‑time PCR detects HPV DNA and discriminates individual genotypes by amplifying genotype‑specific genomic targets.
