2 www.ias2013.org Kuala Lumpur, Malaysia, 30 June - 3 July 2013 Relevance of HIV testing “Whatever … scientifically proven HIV treatment or prevention strategies (PreP / TasP) they will share a common denominator for implementation: the HIV test. They all begin with learning one’s HIV status.” Walensky et al. Plos Med 2011 discussed

22 www.ias2013.org Kuala Lumpur, Malaysia, 30 June - 3 July 2013 Discussion Diagnosis at acute HIV infection stage is associated with HIV–test initiated by healthcare providers –42% of patients diagnosed in acute stage vs. 29% of those diagnosed in chronic stage  Inform and train healthcare providers to Symptoms related to HIV infection HIV testing: systematic offer, regular offer for HIV exposed population Acute infection: HIV RNA measure rather than EIA test Champenois et al. BMC Infect Dis 2013; Yazdanpanah at al. Plos One 2010

23 www.ias2013.org Kuala Lumpur, Malaysia, 30 June - 3 July 2013 Discussion Diagnosis at acute HIV infection stage is associated with History of testing: recent and frequent –Promote different HIV testing strategies Care provider-based HIV testing Community-based VCT Out-reach rapid testing in sex venues … Champenois et al. BMJ Open 2012; Greacen et al. AIDS Care 2012

24 www.ias2013.org Kuala Lumpur, Malaysia, 30 June - 3 July 2013 Discussion Strengths and limitations –Enrollment of 1/5 MSM newly HIV diagnosed in France Results extrapolated to MSM who live in France –Study not designed especially for MSM and had another main objective Sexual behaviour could not be studied in detail

25 www.ias2013.org Kuala Lumpur, Malaysia, 30 June - 3 July 2013 Conclusions 21% of MSM were diagnosed at acute HIV-infection stage How to improve early HIV testing in MSM? Promote HIV–test initiated by healthcare providers –Improve knowledge and training Promote repeated testing in MSM –Recommendations of >1 test / year –Extend HIV-testing offers –Complementarity strategies
