The German HIV-1 Seroconverter Cohort Barbara Bartmeyer Robert Koch-Institute, Berlin Dept. Infectious Disease Epidemiology HIV/AIDS, STI Unit www.rki.de

Aims Influence by host and virus on HIV disease progression in patients with a known date of infection Host - HLA and TLR-receptor polymorphism (Cooperation: Charité, University Medicine Berlin; University of Erlangen) - co-receptor polymorphism (Cooperation: Charité, University Medicine Berlin) - STI-screening Virus - spread and transmission of drug resistance - persistence and viral fitness - minority resistance cART - first line, second line, treatment success, switch 2

Methods - study design • Prospective multi centre study (since 1997) • Inclusion criteria Documented seroconverters - last negative and first positive HIV-Test ≤ 3 years - date of infection: mean between both tests Acute seroconverters - HIV RNA+, EIA– or EIA+ and indeterminate WB - date of infection: approximation to first reactive test 3

Methods – genotypic resistance analysis • pol -population sequencing • Identification of resistance associated mutations: - IAS-Liste 2007; - Surveillance drug resistance list 2007, SDRM list (Shafer R. et al. 2007) • Prediction of phenotype - Stanford algorithm (http://hivdb.stanford.edu, version 4.3.1,Sep 2007) levels of resistance: sensitive: sensitive + potentially resistant intermediate: low + intermediate resistant highly resistant 4

Results – study population • study population genotyped (04/2009) 1412/1625; 87% • sex 95% male; 5% female • MSM 87% • IDU 1.5% • Heterosexuals 6% • HPC 2% primary resistance 152 (11%, CI 9.3 - 12.8) sex 146 men (96%), 6 women (4%) age 34 (IQR, 27-39) CDC classification 96% A, 2% B, 0%C CD4 cells (cells/µl, median) 428 cells/µl HIV RNA (copies/ml, median) 115,000 copies/ml • 5

STI -Screening 12

Methods – STI screening STI-Screening: n=1285 (antiretroviral naive HIV-1 Seroconverter samples 1996-2007) Methods: - HBV: anti-HBc; anti-HBs; HBsAG - HCV: anti-HCV-EIA; anti-HCV-immunoblot; - HSV-2: HSV-2 IgG; HSV-2 IgM - Syphilis: syphilis screening; FTAG; FTAM; VDRL 13

Conclusion Drug resistance • Significant decrease NRTI resistance • Increasing trend of NNRTI resistance (Y181CI; G190AESQ) • Mainly singleton resistance (PI, NNRTI) STI • Trend of increasing syphilis among MSM • Increasing HSV-2 IgM in the study population • Increasing prevalence of HCV among MSM 20
