This morning I attended the Oral presentations for HIV/STI testing and management, looking at different studies around HIV risk.

Brendan Harney from Melbourne presented his study: Risk of HIV following repeat sexually transmissible infections among men who have sex with men in Victoria, Australia. 

This presentation was a retrospective study questioning, if MSM have repeat positive STI diagnoses, are they at an increased risk of HIV transmission? 

Out of 8941 MSM (median age 29, Australian born) surveyed at a busy Melbourne Sexual Health Centres, 2.5% were diagnosed as HIV positive.

Although repeat Chlamydia and Syphilis notifications were common, Rectal gonorrhoea was found to be the highest, with 13.5% of those with a repeat positive gonorrhoea rectal infection becoming HIV positive.

Conclusion? Repeat Gonorrhoea infections are strongly associated with a HIV infection, and that this data is key to looking at PrEP inclusion criteria and why we target specific groups and behavioural activities for PrEP enrolment studies.
