Acute HBV & HCV Infection Among MSM: CDC Data from Population-Based Surveillance, 2006-2008
  Reported by Jules Levin

Div of Viral Hepatitis, CSC Atlanta, Ga
From Jules: This CDC reports only 14 adult MSM who are infected with acute HCV. Of these 14 6/12 report injection drug use, 9/12 report multiple sex partners, 0/6 report sexual contact with a confirmed or suspected case of HCV, and 12/14 report 1 or more drug or sexual risk factors listed above. As you may know European researchers from major cities in Western Europe including London and Paris have reported numerous cases at conferences of acute HCV among MSM with HIV due to unsafe sexual behavior and not IV drug use. Here in the USA the only recent research into this phenomenon has come out of NYC's Mt Sinai Hospital and Daniel Fierer, MD who has conducted research and reports finding a similar phenomenon and in addition reports accelerated HCV progression among already HIV-infected individuals who then experience acute HCV-infection, and these individuals are reportedly infected through unsafe sex. This CDC report below reported at ICAAC is data collected through the CDC surveillance system, while the European data was collected and reported by the hospital clinics in London and other cities, so a more reliable system. In the USA prior to the Mt Sinai reporting the only organized data reported was from San Francisco, but on the whole there has not been a concerted effort from major USA cities to try to gather this kind of data. Granted the care system and the epidemic is different between Western Europe and the USA where I think it allows hospital clinics in Western Europe to be more able to collect this type of information. Here in the USA we have a large patient population of African-Americans infected with HCV and HCV/IV coinfection through IV drug use and our hospital clinics are consumed with this epidemic with large numbers of patients. While in Western Europe they do not have as many HIV patients, here in the USA we have 1 million with HIV diagnosed and the numbers in Europe are much smaller. This allows the Europeans to focus much more on MSM in their clinics and the epidemic of HIV+ MSM who contract HCV through sexual transmission by unsafe behavior, perhaps HCV infection as has been reported is due to the recent increased phenomenon of circuit sex patties in major Western European cities, and also the apparent and reported connection of infected individuals who appear to travel between these cities and the phylogentic connections researched and reported between MSM purported traveling between these cities. This phenomenon if it exists in the USA has not been researched and reported.
