Natural History of HPV Infection in Men: The HIM Study

Completed

• Conditions: Human Papillomavirus

• Registration Number: NCT00786760
• Lead Sponsor: H. Lee Moffitt Cancer Center and Research Institute

Brief Summary

The purpose of this study is to learn about the natural history of Human Papillomavirus (HPV) infection in men. The study will also find out what factors are linked to HPV in men including other sexually transmitted diseases (STDs). If participants test positive for syphilis, gonorrhea or chlamydia, we are required by law to report the results to the Florida Department of Health. Participants will be able to get free medical treatment from the Florida Department of Health for these STDs. Participants will be given a written report of the results of the STD testing.

Detailed Description

The study protocol will include a pre-enrollment run-in visit, a baseline visit (enrollment), and 8 additional visits after enrollment scheduled 6 months apart. Intervals of every 6 months were chosen to insure that both acquisition and loss of infections may be assessed, as studies in women indicate that median duration of oncogenic infections ranges between 7-9 months. Informed consent will occur during the run-in visit. The run-in and follow-up visits will include questionnaire administration, visual inspection of the skin and external genitalia, and the collection of urine, blood, oral cells, and penile skin samples If anogenital lesions are present at any of the clinic visits, they will be sampled as well.

Primary Outcome Measures

Name	Time	Method
Cohort Selection	3 years, 3 months	The first specific aim is to establish the cohort of 3000 men ages 18 - 44 years who will be examined every 6 months for 4 years. To assess potential biases introduced by the run-in visit, Pearson's χ² test of association will be used to compare cohort participants and non-participants who attended the run-in visit with respect to known and potential HPV risk factors and HPV status. All analyses will be conducted using Intercooled STATA (StataCorp. 2001. Stata Statistical Software: Release 8.2 SE College Station, Texas: Stata Corporation).

Secondary Outcome Measures

Name	Time	Method
Incidence Rates of Specific HPV Type Infection	4 years per participant	The second specific aim is to determine the incidence and persistence of type-specific HPV infections. Estimates of the incidence rates of specific HPV type infection will be calculated on the basis of the number of cases in which a given type is detected for the first time in men who tested negative for that HPV type at baseline.
