Injecting Drug Use and HIV, HCV
infections in Dakar, Sénégal :
From Research to Implementation,
the UDSEN project
Pierre-Marie GIRARD,
Hopital St Antoine & IMEA, Paris and
ANRS Sénégal Site, for the
UDSEN Study Group
Starting point - ICASA 2008, Dakar
• A qualitative Rapid Assessment Study
Injectable Drugs Use
(2004-2005) confirmed
•The legal and social context of drugs use was repressive.
•Very few care givers involved in IDU .
=>PWID/PWUD = hidden populations
•Poor experience of HCW on drug use (« drugs » mean only
Cannabis)
• Willingness of HIV experts and HCW to face this challenge
(CNLS/SMI Fann/Saint Antoine Hospital /ANRS/IMEA /ESTHER).
=> Implementation of an Operationnal research based on a
prevalence estimation of HIV/HCV/HBV by Respondent Driven
Sampling (RDS) method

UDSEN study: Objectives
• To provide objective data on:
– IDU prevalence and size of the population
– Practices
– HIV/HCV/HBV prevalence
• HCW and Social Workers training
• Advocacy for harm reduction programs
• Advocacy for access to HAART in IDU
Ethical Issues
• Security & confidentiality for participants :
– Setting of the survey in Clinical and Research center of
Centre Hospitalier de Fann
– Anonymous consent form
– Intensive training of HCW and staff members on addictions
issues and confidentiality
• Amount of incentive: the same as current amount for clinical
studies participation in the center
• Care access for all the recrutees :
– Prevention kits & counselling.
– Access to tests results and care
= 18-month duration for study preparation
UDSEN study (ANRS 12243): methods (1)
• Outreach program in the 4 previous months
• Settings: All 4 departments of Dakar area.
• Inclusion criteria: heroin and/or cocaine use in the
previous 3 months whatever the use patterns (=IDU).
• Size estimation by capture/recapture method :
– Capture : cardboard token distribution at W-1 RDS
survey
– Recapture : participation to the RDS survey.
UDSEN study (ANRS 12243): methods (2)
• Recruitment of IDUs for estimation of prevalence in
the population: Respondent Driven Sampling (RDS) :
8 seeds representative of the diversity of the
population.
• RDS, social and behavioral questionnaires.
• Biological assessment for HIV antibodies, HBV (HBs
Ag and HBc Ab) and HCV (DBS).
• Counselling and kit prevention
UDSEN study : Main Results
(April to July 2011)
• Size estimation of IDU in Dakar area:
1324
(IC95%: 1281-1367).

–HBV (Hbs+ Ag) : 8.9% [IC95%(5.211.1)]
–HCV (HCV Ab) : 23.3% [IC95%
(21.2-25.2)]
UDSEN study: Main results (2)
HIV/HCV/HBV prevalence
HIV:
•Injectors*vs Non-injectors: 9.4 % vs 2.5%
• Women vs Men: 13% vs 3%
HCV:
•Injectors vs Non-injectors: 39 % vs 18%
No statistic difference in gender
HBV: AgHBs + : 8.9%
*injection at least once lifely
Risk factors for HIV and HCV
• Risk factors for HIV
– Female sex (OR = 4.9, 95%CI: 1.6 – 15.6) p= 0.007
– Past or actual injection (OR = 4.3, 95%CI: 1.7 – 10.7) p= 0.04
– Age (OR per year) (OR =1.1, 95%CI:1.004 – 1.1) p= 0.03
• Risk factors for HCV
– Past or current injection (OR = 2.7, 95%CI: 1.7 – 4.3) p= 0.0001
– To be single, divorced or widowed (OR = 1.81, 95%CI: 1.08 –
3.04) p = 0.02
– Duration of relationship with study recruiter (OR per days) (OR =
1.001, 95CI: 1.0 – 1.002) p = 0.05
All results are generated through mutivariate analysis
