1 Challenges of Treatment of Hepatitis C in the Incarcerated US Population USPHS Scientific and Training Symposium June 23, 2011 Dr William Resto-Rivera MD, USPHS Kiesha Resto Pharm D, USPHS

2 Objectives # 1) Compare Hepatitis C Virus (HCV) infections in prison population versus the regular population. #2) Analyze the challenges of identifying and treating prison population. #3) Review common & rare side effects that are related to Hepatitis C therapy. #4) Discuss challenges in treating patients with co-morbid conditions. #5) Review recent FDA approved medications for HCV.

3 US Hepatitis Statistics 1.3% US population infected Hepatitis C Virus (HCV) 29-43% People infected with HCV will pass through US prison system every year 16-40% US Prison population infected with HCV Reference #4

4 Population Baby boomers account for 2 out of 3 cases of HCV patients. Peak prevalence men born in early 1950’s HCV is over-represented in African Americans. Reference #5

5 Every 100 people infected with HCV 75-85 develop chronic infection 60-70 develop chronic liver disease 5-20 develop cirrhosis 1-5 die from cirrhosis or liver cancer

6 Center of Disease Control & National Institutes of Health Convention January 2003 identified 5 optimal approaches to Screening & treating HCV in US prisons #1 Testing of HCV in Prisons would identify many Infected Americans #2 Prison Substance Abuse programs would decrease HCV infections & future prisons cost #3 Patients can be Selected using Published Guidelines #4 Prisons Treatment Reflects Community Standards and Require Sufficient Medical Workforce #5 Collaboration Between Correctional & Public Health Systems is Needed Reference #14

7 Factors for Treatment Screening Screening and Diagnosis of Hepatitis C individuals. Screening for candidates for treatment Safety, Efficacy & Cost Monitoring Laboratories and ADR Patient Tolerate treatment Viral Response to treatment EVR/SVR Source of funding

8 Hepatitis C Not a Routine Universal Screening Routine screening based on 4 criteria: Amenable to treatment Interfere with activities of daily living Progress without treatment during time of incarceration Risk of transmission Reference # 14

9 To Screen or to Not Screen Rhode Island State Corrections Screened all incoming inmate 4263 Males – 23% + HCV 499 Females – 40% HCV Out of inmates who tested + HCV 66% did not report high risk behaviors Wisconsin State Corrections 91% HCV infected inmates identified through testing 27% of population with risk factor IVDA Indiana State Corrections Universal testing found 13% of population HCV (+) Reference #16Reference #14

31 Summary Prison are an ideal setting to treat a large population of HCV (+) people. Screening for HCV need to be examined cost/benefit per institution. Treating patient while incarcerated can be a cost saving to society HCV treatment is associated with multiple side effects that need an educated multidiscipline approach to manage

32 Summary Guidelines are established for screening and to help guide management of adverse events. Patient with co-morbidies are an increase challenge to treat but can be treated safely and effectively with proper monitoring. New Antiviral medications just approved will improve overall outcomes in the future.
