Early studies of HCV in MSM • 1990’s - HCV prevalence: up to 23%1-3 • MSM no IVDU: 1-7% 4,5 • MSM IVDU: 25-50%5,6 • MSM HIV-: 0-19%7,8 • MSM HIV+: 3-39%7,8 While sexual transmission may occur, IVDU is the major transmission route for HCV in MSM, while HIV may play a role in enhancing transmission 1.

Sexual transmission cause of recent AHC epidemic? • HCV RNA in semen • 2X more frequently in HIV+ MSM1 • Concomitant STIs • Increased ‘unsafe’ sex since late 1990’s2,3 • UPAI / STS / Serosorting • Precedent set: epidemic LGV4 1.

Evidence for Sexual transmission • All HIV+ patients with AHC 1999-2005 • n = 111 • Mean age 36yrs, all MSM • 84% G1 • 65% on ART • mean CD4 552 • Phylogenetic analysis • Case-control study • 60 cases: 130 matched controls • Questionnaire (drug & sex behaviour 12 mnths pre AHC)
7 genetically distinct clusters (largest n = 43) • 76% sequences included in a cluster • 64% line divergences since 1995 G3 7 G1a 1 2 G1b 3 6 4 5
Case-control study results Sex Drugs 82% cases no IVDU Increased: none IVDU drug use shared implements sex under influence (91.7% vs 61.5%; P<0.001) Multivariate analysis After adjusting for group sex – no longer significant • Increased: • sexual partners (30 vs 10) • internet to meet partners (7X) • UPAI / fisting & sex toys / group sex • Multivariate analysis: • Group sex: R/I UPAI & fisting • Participation in 2: OR 9 • Participation in ≥ 3: OR 23 Danta M et al.
