  2. Topics to Be Covered • HEPCAP Study • HALO Study • Take Home Points: Impact on you as a provider

  3. Hepatitis in Correctional Settings: the California Experience

  4. HEPCAP OBJECTIVES*HCV infection among inmates - entry  *HCV infection among correctional staff *HCV treatment candidacy among staff *Hepatitis A virus infection among inmates *Inventory HCV education, prevention and training materials for staff and inmates *HCV infection among inmates - exit (parolees) 

  5. Hepatitis C Among Inmates: Prisoner Entry Study • What is the prevalence of HCV infection among inmates? • What are the risks and behaviors associated with HCV? • Are there differences between men and women? • Do inmates know their HCV status?

  6. HEPCAP Prisoner Entry Study • Spring / Summer 2002 • “Piggybacked” on CDC’s Hepatitis C Pilot • 472 inmates volunteered out of 615 approached • 3 CDC facilities: 2 male, 1 female • Great support from CO’s, MTAs and other Staff • Involved a blood sample and a one-to-one risk interview with inmates at reception at these facilities

  7. HEPCAP Prisoner Entry Study Results • 34% prevalence of HCV antibody • HCV infection among inmates is associated: • with gender (39% female vs 32% male) • with race (60% White, 53%Latino, 20%Af-am) • IDU (65% vs 10%)

  8. HEPCAP Prisoner Entry Study Results • Among those with no history of IDU, HCV was associated w/ total time incarcerated • Parole violators almost twice as likely to have HCV • No associations with tattooing, snorting or assaults • Only 32% had ever tested for HCV but 73% had tested for HIV

  9. HEPCAP Prisoner Entry Study Results • 77% HS Education or below • 7% English as a second language • 77% volunteered to participate w/o incentive • Women get tested more than Men

  10. Strategies for Counseling, Prevention, and Education • Prevention Message = blood to blood • Develop programs at Juvenile facilities, with first-time offenses and/or first-time drug convictions • Prisoners are diverse: different messages for different cultures, gender, languages, level of need • “If you build it they will come”: voluntary testing and education should be encouraged and provided

  11. Strategies for Counseling, Prevention, and Education • Double-dipping: testing for HIV - why not HCV too? • Community and Public health issue: • Parole violations / release • More collaboration with public health is needed • Vaccination programs for hepatitis A and B • Treatment opportunities • Peer education: Cost-effective option • $$$$: Extra correctional staff / support is required to deal with HCV prevention and disease management

  12. Hepatitis C Among Correctional Staff HEPCAP Staff Study Given the large number of infected inmates: • What is the prevalence of HCV infection among correctional staff? Does it differ by job duties? • Are staff at risk of HCV infection? • How can we prevent transmission among staff? • What can we do to support HCV positive staff?

  13. HEPCAP Staff Study • Involved an interview, pre-test counseling and education and blood test for HCV • 1,401 hours spent 1-1 with correctional staff • 10 months across the state • Participation > expected = longer period at each facility • Included 6 facilities (4 CDC/2 CYA)

  14. HEPCAP Staff Study Who participated? • 1,012 staff participated 78% return for test results • 83% had never been tested for HCV • Included staff from all job categories at each facility • 36.6% correctional officers • 17.7% health care persons (including MTAs) • 27.0 % non-medical, non-custodial • 18.3% administrative staff • 4.0% other

  15. HEPCAP Staff Study Results:THE GOOD NEWS… • 2.1% prevalence of HCV antibody (confirmed) • Comparable to the general US population

  16. HEPCAP Staff Study Results:THE BAD NEWS… • 57% of correctional staff reported blood or bodily fluid exposures at work • 37% believed that they didn’t always have time to follow universal precautions

  17. HEPCAP Staff Study Preliminary Results:While working at corrections: • 10% had been stuck by a needle or syringe • 13% had been stuck or cut with another sharp object • 35% blood/body fluid splash/skin contact (excluding their eye, nose or mouth) • 15% blood/ body fluid splash/direct contact with their eyes, nose or mouth

  18. HEPCAP Staff Study Preliminary Results:Odds of exposures vary by job: • 54: 1 Medical staff ever being stuck or cut with a needle compared to admin staff • 7:1 Correctional officers ever being stuck or cut with a sharp object compared to admin staff • 2:1 Non-medical, non-custodial staff ever having blood / body fluid splash or make contact with their direct skin OR eye, nose or mouth compared to admin staff.

  19. Strategies for prevention, education and counseling: Correctional Staff • Universal precautions in a correction-specific environment (ie. locked doors) needs to be addressed • Include all job areas (with exposures) AND staff levels in BBP and related training • “If you build it they will come”

  20. Strategies for prevention, education and counseling: Correctional Staff • “Different strokes for different folks”: provide different types of training - on-the-job, take home, “outside experts”, more frequent and shorter • Encourage testing: Possible link with annual TB testing or hepatitis A/B vaccine programs? • Support: Immediate response, increase post-exposure support, decrease paperwork!!

  21. HCV Resources for Staff and/Or Inmates: • All facilities had HCV prevention materials available: in various media (print, video, posters, etc) • Areas for improvement: standardization, improve quality, temporal relevance, accessibility/applicability in all units or job areas, proactive vs. reactive • Some excellent peer education models (ie.kitchen at 1 prison) • Whose responsibility? Often dependent on unpaid staff/inmate initiative • Inmates and Staff want more!!

  22. WHAT NEXT? Still a lot of work to be done: • High prevalence, high risk behaviors of inmates and parolees • Continued BBP exposures to staff • Prevention and education is CHEAP • Inmates and staff want more HCV testing, education and support

  23. THANKS TO YACA (CDC, CYA AND PAROLE REGION #2) AND CCPOA HEPCAP WANTS TO THANK YACA, THE CDC, THE CYA, INMATES, WARDENS, CCPOA, CORRECTIONAL OFFICERS, MTAS, PAROLE ADMINISTRATORS AND STAFF WHO PARTICIPATED IN, OR ASSISTED US IN OUR INMATE, PAROLEE AND CORRECTIONAL STAFF STUDIES

  24. A prospective study to examine persistent HCV reinfection in injection drug users who have previously cleared the virus Sue Currie, Daniel Tracy, Sally George, Hui Shen, James Ryan, Alan Kennedy, Michael Kim, Alexander Monto University of California, San Francisco San Francisco VA Medical Center

  25. Background • IDU is a primary and efficient route of HCV transmission • NHANES data suggest 48.4% of all HCV positive persons have hx of IDU • Pre-2002: Recent IDU was a common exclusion for HCV antiviral treatment • 2002: NIH Consensus Statement broadened criteria to include recent IDUs for consideration for HCV Tx • 2006: Still limited access to HCV Tx for recent IDUs, partly due to concern for HCV reinfection

  26. Background (cont’d) Is the concern for HCV reinfection founded? • Studies in chimpanzees suggest that clearance of HCV is associated with immunological resistance to reinfection • Limited longitudinal data in humans

  27. Study Purpose To determine whether IDUs who have resolved the HCV virus and who continue to inject drugs get reinfected with HCV

  28. Methods • Longitudinal cohort: • 396 HCV antibody positive persons current • History of injection drug use at enrollment • Baseline and q 6-monthly follow-up: • HCV risk factor data (including detailed drug use history) • Serum collected • Serial serum samples tested for HCV RNA using quantitative and qualitative assays

  29. Methods (cont’d) • Inclusion Criteria: 3 or more visits (baseline and at least 2 follow up visits) • Resolvers: persons who were HCV antibody positive and HCV RNA negative through spontaneous resolution OR HCV antiviral treatment • Reinfection: persons with documented HCV viral resolution followed by the presence of HCV RNA at 2 or more visits

  30. Results • 224 persons with 3 or more visits • 186 chronic HCV RNA positive • 38 resolvers: 29 spontaneous and 9 HCV tx-associated • No difference in age, income, HIV status, recent alcohol use between groups • Resolvers were more likely: • female • less educated • have had a hx of incarceration • not to have been injecting drugs at enrollment

  31. Results (cont’d): • Over 1,391 person years of follow-up • 103 participants reported IDU at some or all of their follow-up visits for a total of 399 person-years of IDU • No difference in length of time of IDU between resolvers and chronic HCV RNA+ group

  32. Results: Baseline demographics and behaviors of study population

  33. Follow-up of Study Population (N = 224)

  34. HCV RNA Results of HCV Resolvers *Reinfected individual has GT2, HCV RNA VL >5million IU/ml

  35. Conclusions • In HCV resolvers, despite active IDU and therefore potential ongoing exposure to HCV virus, reinfection appears to be a rare event • Concern for reinfection should not be a barrier to HCV antiviral treatment for persons who are at risk for ongoing or future IDU • Majority of IDUs who were treated did not re-engage in drug use • Further study is required to evaluate possible factors associated with protective immunity against HCV reinfection

  36. Limitations • IDU is based on self report • No current GT data available on Spontaneous resolvers • Since rate of reinfection is so low, it is hard to identify other potential factors associated with it
