Infection with multiple types of human papillomavirus in sexually active young women

Abstract

Study design: cross. Study objective: estimate the frequency and distribution types of human papillomavirus (HPV) in sexually active young women. Methods: samples of vaginal and endocervical canal of 158 women, aged between 18 and 35 years were collected through self-collection technique. The HPV DNA was extracted and amplified by PCR end point using the consensus primers PGMY09/11 and genotyping was performed by PCR specific type (TS-PCR) and by analysis of the fragments obtained from the use of restriction enzymes (RFLP). Results: HPV DNA was detected in 23% of participants, 92% were high-risk HPV genotypes (HR), being the prevalent HPV45, followed by HPV16 and 31 infections with multiple HPV types were detected in 35% of samples, indicating infection by more than two types in 22.2% of the genotyped. Higher frequency of HPV DNA was detected in women ≤ 25 old. Conclusion: this demonstrated a high frequency of HPV infection in sexually active young women, as well as a high prevalence of infection with multiple types of high oncogenic risk
