简要总结
Infection with human immunodeficiency virus (HIV) is an important risk factor for HPV infection and the development of HPV-associated lesions in female and male anogenital tract. Data on safety and immunogenicity of quadrivalent human papillomavirus vaccine in HIV-infected population are few. The present study is a non-randomized controlled clinical trial with the primary objective to determine safety ad immunogenicity of quadrivalent human papillomavirus vaccine (Gardasil®) in HIV-infected female and male adolescents and young adults.

研究组 & 干预措施
HIV-infected adolescents and young adults
female and male HIV-infected subjects aged from 13-27 years old
干预措施: Quadrivalent Human Papillomavirus (6, 11, 16 and 18) vaccine (Gardasil ®) (Biological)

结局指标
主要结局
type specific antibody titers for HPV types 6, 11, 16 and 18 at one month after completion of HPV vaccine series (T3) in HIV infected subjects vs. healthy subjects
时间窗: one month +/- 10 days after 3° vaccine dose
Immunogenicity of quadrivalent human papillomavirus vaccine (Gardasil®) will be assessed by evaluation of type-specific antibody development for HPV types 6, 11, 16 and 18 from seronegative status at baseline (T0) to seropositive status at one month after the completion of HPV vaccine series (T3), compared with the same immunogenicity testings performed in healthy subjects matched for sex and age.
次要结局
- HIV viral load and lymphocyte CD4+ count(baseline (T0), one month after each vaccination dose (T1, T2 and T3) and at month 12 (T4) and 18 (T5) from baseline.)
- antibody HPV titers to types 6, 11, 16 and 18, one month after the first two vaccination series (T1 and T2) in HIV-infected subjects vs healthy subjects(one month +/- 10 days after 1°vaccine dose and month+/- 10 days after 2° vaccine dose)
- antibody titers to HPV types 6, 11, 16 and 18 at month 12(T4)and 18 (T5)from baseline (T0).(12 months +/- 10 days and 18 months +/-10 days from baseline)
- local and systemic adverse events(7 days after each vaccination dose)
- lymphoproliferative responses, cytokine production and immunophenotype analysis of lymphocyte subpopulations(baseline (T0), one month after 1° vaccination dose (T1) and one month after 3° vaccination dose (T3).)
