HIV Infections Sexual Behavior Risk Reduction | Other: Determine the Incidence and Retention Rate |
In Germany, new HIV diagnoses are steadily increasing again since 2000. 74% of infected individuals living in Germany are men who have sex with men (MSM) whereas only 15% were infected by heterosexual contact. The HIV epidemic is mainly restricted to big cities such as Cologne, Berlin, Hamburg. The successful conduct of HIV vaccine efficacy trials requires recruitment, enrolment, and long-term retention of informed, willing, and HIV-negative but at-risk participants. Therefore, the University Hospital Essen plans a vaccine preparedness study to assess the feasibility of future HIV vaccine efficacy trials in Germany, a subtype B prevalent region in Europe, as this has never been assessed in Germany.
Notably investigators conduct a cohort study to characterize HIV incidence and retention among high risk, HIV uninfected MSM/Transgender women (TGW)/Transgender Men (TGM)/Intersex in the setting of prevention modalities that may be available to participants, including PrEP and regular HIV risk reduction counselling and testing. The design of the study will address several unique questions about the community at highest risk for HIV infection and will provide strong data for prevention methods including PrEP.
Moreover, it has been clearly demonstrated that sexually transmitted infections (STIs) can increase the risk of acquiring a HIV infection. Therefore, early diagnosis and treatment of STI is crucial to reduce this risk factor of HIV acquisition and to inform individuals about their risk to become HIV infected. As STIs are a crucial factor in the scope of an incidence analysis of HIV in MSM and are underdiagnosed often, extensive screening measures are implemented within the study to an extent never performed in Germany before.

- Other: Determine the Incidence and Retention Rate
Determine the incidence of HIV and the retention rate of MSM/TGW/TGM/Intersex at risk for HIV infection
- Incidence of HIV in a cohort of MSM/TGW/TGM/Intersex at risk for HIV infection [ Time Frame: Through study completion, an average of 2 years ]Descriptive statistics will be generated to summarize incidence (as measured as new HIV infections occurring during the study period) HIV infections. The power calculation targets a 3% incidence rate per year. An overall estimate of HIV incidence and 95% confidence intervals (CI) will be estimated assuming a Poisson distribution.
- Retention rate of MSM/TGW/TGM/Intersex at risk for HIV infection in a cohort study [ Time Frame: Through study completion, an average of 2 years ]The primary assessment of retention will be conducted assuming a binomial distribution and individuals will be considered retained at 12 months if they complete the final study visit. Retention will also be estimated with a 95% CI for each study visit. Factors associated with overall retention will be assessed in a logistic regression model.
- Prevalence of HIV infection among screened participants [ Time Frame: At screening (until last participant in), an average of 1 year ]Descriptive statistics will be generated to summarize prevalence (as measured as HIV positive cases study period) HIV infections. Once enrolment is completed, baseline HIV prevalence will be calculated.
- Relationship between certain behavior and risk of HIV infection [ Time Frame: Through study completion, an average of 2 years ]Participants will receive questionnaires. The risks of HIV infection will be based on factors such as sexual behavior, pre- and post-exposure prophylaxys and others. Descriptive statistics will be generating to summarize risk factors associated with HIV infection.
- Willingness of MSM/TGW/TGM/Intersex at risk for HIV infection to participate in a future HIV vaccine trial [ Time Frame: At visit 1 and 5 (visit 1 is day 0, visit 5 is day 364) ]Willingness to participate in an HIV vaccine trial will be estimated assuming a binomial distribution. Factors associated with willingness to participate in vaccine trial will be evaluated using logistic regression models.
- Prevalence of STIs in MSM/TGW/TGM/Intersex at risk for HIV infection [ Time Frame: At screening (until last participant in), an average of 1 year ]Descriptive statistics will be generated to summarize prevalence (as measured as STIs positive cases study period) STI infections. Once enrolment is completed, baseline STI prevalence will be calculated.
- Incidence of STIs in MSM/TGW/TGM/Intersex at risk for HIV infection [ Time Frame: Through study completion, an average of 2 years ]Descriptive statistics will be generated to summarize incidence (as measured as new STI infections occurring during the study period) STI infections. An overall estimate of STI incidence and 95% confidence intervals will be estimated assuming a Poisson distribution.
- Attitudes regarding pre-exposure prophylaxis (PrEP) among MSM/TGW/TGM/Intersex at risk for HIV infection [ Time Frame: At screening and at visit 1,2,3,4 and 5 (visit 1 is day 0, visit 2 is day 84, visit 3 is day 168, visit 4 is day 252, visit 5 is day 364) ]Attitudes regarding PrEP will be evaluated using questionnaires. Behavioural questionnaire over time will be assessed by frequency tables and bar graphs.
- Relative HIV incidence between MSM/ TGW/TGM/Intersex across sites [ Time Frame: Through study completion, an average of 2 years ]Descriptive statistics will be generated to summarize incidence (as measured as new HIV infections occurring during the study period) HIV infections. The power calculation targets a 3% incidence rate per year. Data may be compared across sites for comparison and evaluation of factors impacting incidence.
