French Disease to Ipergay: Syphilis networks in the PrEP era
John Schneider, MD, MPH

Dr. Schneider will describe syphilis networks of most at risk populations in the United States and in particular, younger Black men who have sex with men. He will present comparisons of these networks with HIV networks and the implications of co-infection. He will spend a significant amount of time contextualizing both networks within the era of PrEP and describe ongoing and novel network interventions to limit the impact of ongoing domestic syphilis epidemics.

Presentations in the Series

A Journey through Syphilis: How does Treponema pallidum cause such a complex disease?
Sheila Lukehart, PhD

A-Journey-through-Syphilis

Syphilis is a disease that comes and goes, with manifestations affecting many different organ systems. The clinical course is the result of interactions between the host’s immune response and the bacterium’s ability to overcome or evade that response, a duel that can last a lifetime. This presentation will focus on our evolving understanding of these host and bacterial mechanisms, and their implications for syphilis control.

STDs, the Genital Microbiome and HIV Transmission: What is Happening Down There?

Dr. Rupert Kaul

STDs, the Genital Microbiome and HIV Transmission: What is Happening Down There? Dr. Rupert Kaul

Antiretroviral therapy (ART) dramatically reduces HIV transmission when used as treatment or as PrEP, but the global rate of new HIV infections currently outstrips our ability to provide ART. Most of these new HIV infections are acquired through sex, when the mucosal lining of the vagina, penis or rectum is exposed to HIV-infected genital fluids. Sexual HIV transmission is surprisingly inefficient, with a per-contact risk under 1% for most exposures. Today’s presentation will focus on how this risk is dependent on the dynamic interaction between our immune system and microbes – both HIV, other STIs and the larger microbiome – at the mucosal surfaces of the genital tract and gut, and will highlight some challenges of translating these research findings into new HIV prevention strategies.


Comprehensive Sexual Health Care for Sexual and Gender Minority Patients in the HAART and PrEP Era
by Kenneth Mayer, MD

by Kenneth Mayer

Sexual and gender minority patients have experienced sexual health disparities that are partially related to behaviors (e.g. frequent partner change among some subgroups), biology (e.g. increased susceptibility of the rectal mucosa to HIV and several other STIs), and structural factors (e.g. lack of culturally competent care, unsupportive socio-political environments). The advent of highly active antiretroviral therapy (HAART) and pre-exposure prophylaxis (PrEP) means that individuals can engage in condomless sex without HIV transmission. The implications of the new findings in HIV prevention for STI management and control will be explored in the talk, with suggestions for the development of new paradigms to enhance the sexual health of these populations.

Risks and Resiliencies: HIV and STIs among Gay Men, other Men who have Sex with Men and Transgender Women Globally
by Stefan Baral, MD, MPH, FRCPC

Risks and Resiliencies HIV and STIs among Gay Men, other Men who have Sex with Men and Transgender Women Globally

Risks and Resiliencies: HIV and STIs among Gay Men, other Men who have Sex with Men and Transgender Women Globally by Stefan Baral, MD, MPH, FRCPC

This talk will present the results of recent systematic reviews of the burdens of HIV and STI among gay men, other men who have sex with men, and transgender women in both high and low and middle income settings as well as a discussion of the vulnerabilities that potentiate risks for adverse health outcomes among these populations.

Public Health in a Hostile Environment: Racial Inequality and STD/HIV in the US Adaora Adimora, MD, MPH

Public Health in a Hostile Environment: Racial Inequality and STD/HIV in the US
Adaora Adimora, MD, MPH

 

Adaora Adimora, MD, MPH

It’s now well understood that social factors are a major determinant of HIV and other STDs. But how can we develop relevant interventions? And what are the methodological challenges of social determinants research? This talk will explore how these issues can impact STD epidemiologic research among African Americans.

 

STDs Amplify the Transmission of HIV: Where do we go from here?


STDs Amplify the Transmission of HIV: Where do we go from here?

Myron S. Cohen, M.D.
Since the time HIV was discovered as the cause of AIDS, we have known that a wide variety of STDs amplify transmission of the virus. The biological forces that create such risk are increasingly well understood. The greatest challenge has been to design strategies that link detection and treatment of STDs to reduced transmission of HIV.

From Partner Services to Field Services: The Evolving Role of Public Health Outreach to Control HIV/STDs

Matthew Golden, MD
From Partner Services to Field Services: The Evolving Role of Public Health Outreach to Control HIV/STDs

Recently, Dr. Golden spoke about the evolving role of public health outreach in the area of HIV/STD. Partner services have been a component of public health STD control since the 1940s, but were not initially widely employed to combat the HIV epidemic and were never adequately funded to meaningfully affect rates of chlamydial infection. The advent of expedited partner therapy for gonorrhea and chlamydial infection, a new national emphasis on the HIV care continuum, and HIV/STD program integration are now fundamentally altering the role of disease investigation and outreach in the control of HIV/STD, both in the U.S. and in low income nations. Dr. Golden presented evidence supporting an expanded role for field outreach in the control of HIV/STD and discuss outstanding operational research questions that confront this area of public health practice.

Dr. Golden is the Director of the Public Health – Seattle & King County HIV/STD Program, and a professor of medicine at the University of Washington School of Medicine. He received his BA in history from Grinnell College, his MD and MPH from Johns Hopkins University, and completed a residency in internal medicine and a fellowship in infectious diseases at the University of Washington. Dr. Golden’s research seeks to integrate public health practice with operational research in the area of HIV/STD prevention. Much of his work has related to the implementation of expedited partner services for gonorrhea and chlamydial infection, HIV partner services, and the use of field outreach to improve the HIV care continuum.

Program Science in STI and HIV Prevention – Global Challenges and Emerging Experience
James Blanchard, MD, MPH, PhD
Centre for Global Public Health, University of Manitoba 

“Program Science” is a relatively new construct that has emerged to help address the gap between the domains of public health programs and scientific research. In this presentation Dr. Blanchard discusses the challenges and issues for developing, synthesizing and translating scientific knowledge into the design and implementation of public health programs focusing on STI and HIV prevention. Examples from several different countries in diverse epidemiological and socio-cultural contexts are used to illustrate emerging approaches to improve assessment and program strategies, definition of programs and prevention services, and measuring the progress and achievement of programs.
