Original Study

Background: Studies in women indicate that some sexually transmitted infections promote human papillomavirus (HPV) persistence and carcinogenesis. Little is known about this association in men; therefore, we assessed whether Chlamydia trachomatis (CT) infection and herpes simplex virus type 2 (HSV-2) serostatus are associated with genital HPV prevalence, an early event in HPV-related pathogenesis.

Methods: Genital exfoliated cells, first-void urine, and blood from 3971 men recruited in the United States, Mexico, and Brazil were tested for HPV, CT, and HSV-2 antibodies, respectively. Multivariable logistic regression was used to assess the association of CT infection and HSV-2 serostatus with 4 HPV outcomes (any, oncogenic, nononcogenic only, and multiple infections).

Results: A total of 64 (1.6%) men were CT positive, and 811 (20.4%) men were HSV-2 seropositive. After adjustment for potential confounders, CT was associated with any HPV (adjusted odds ratio [aOR], 2.19; 95% confidence interval [CI], 1.13–4.24), oncogenic HPV (aOR, 3.10; 95% CI, 1.53–6.28), and multiple HPV (aOR, 3.43; 95% CI, 1.69–6.95) prevalence. Herpes simplex virus type 2 serostatus was associated with any HPV (aOR, 1.25; 95% CI, 1.02–1.52), nononcogenic HPV only (aOR, 1.38; 95% CI, 1.08–1.75), and multiple HPV (aOR, 1.33; 95% CI, 1.06–1.68) prevalence. In analyses stratified by sexual behavior, CT infection was significantly associated with HPV detection among men reporting 2 or more recent sexual partners, whereas HSV-2 serostatus was significantly associated with HPV detection in men reporting 0 to 5 lifetime sexual partners.

Conclusion: In this population, CT infection and HSV-2 serostatus were associated with prevalent genital HPV infection. Future prospective studies should investigate whether these infections influence HPV acquisition and/or persistence.

In a large cohort study in men, both Chlamydia trachomatis infection and herpes simplex virus type 2 serostatus were associated with prevalent genital human papillomavirus infection.
