  1. Ass Booty Cooker The ABCs of Viral Hepatitis Heather Lusk 2nd National Conference on Methamphetamine, HIV and Hepatitis February 2, 2007

  2. Hepatitis A Virus (HAV) Overview • In 2005, ~42,000 people infected in the US • 31.3% of U.S. population have been infected • Acute disease -- no chronic infection • Symptoms common in adults • Once resolved, protective antibodies develop and give lifelong immunity

  3. HAV Transmission • Primarily transmitted via fecal-oral route and rarely through blood exposure • Highly infectious and stable in environment for months • Most common transmission through close personal contact with an infected person • Vaccine is available to prevent infection

  4. Hepatitis B Virus (HBV) Overview • In 2005 ~51,000 new infections in US • ~1.25 million in US living with chronic HBV • 4.9% of U.S. population have been infected • 6% of infected adults develop chronic HBV • 90% of infants develop chronic HBV • Often no symptoms in acute stage • If resolved, protective antibodies develop and give lifelong immunity

  5. HBV Transmission • Transmitted by blood, semen, vaginal fluids • Highly infectious, stable in environment for at least 7 days • Most common transmission through:  perinatal (mom to baby)  unprotected sex  percutaneous (through opening in skin) • Vaccine is available to prevent infection

  6. Hepatitis C Virus (HCV)Overview • In 2005, ~20,000 new infections in US • ~4 million* in US have been infected • 1.6% of U.S. population have been infected • 55%-85% of adults have chronic infection • Often no symptoms in acute stage • If resolved, no protective antibodies *Recent analysis indicates closer to 5 million since NHANES didn’t include homeless, incarcerated etc.

  7. HCV Transmission • Transmitted by direct blood-to-blood contact • Highly infectious, stable in environment for at least 16 hours but not longer than 4 days • Most common transmission through sharing of injection drug use paraphernalia • Also blood transfusions & products before 1992 • Perinatal transmission (4% chance, 19% HIV/HCV+) • Needle stick/healthcare exposure (1.8%) • Sexual transmission • Other blood risks low/unknown risk: tattooing/piercing intranasal cocaine use, shared personal items

  8. HCV TransmissionSharing Injection Equipment • Studies have found high rates of HCV in IDUs who didn’t share syringe, but shared cooker, cotton, water or other paraphernalia • People who inject other things (steroids, vitamins, silicone and hormones) may also be at risk • IDUs should use new, sterile equipment every time (clean hands, injection site and surface too) • It is unknown if bleach kills HCV

  9. HCV TransmissionSexual Transmission • Seven US studies of long-term discordant partners found 1.5 - 3% seroprevalence of HCV • Other studies of MSM, sex workers, and those with history of STD found prevalence of 4-6% • Risk may be increased when trauma is present • Other factors related with sexual transmission include # of partners, the presence of other STDs, and use of condoms

  10. HCV TransmissionLow/Unknown Risks • Non-professional tattooing (prisons tattoos etc): some studies find higher rates of HCV in persons with tattoos • Intranasal cocaine/meth use: Some studies have found link to HCV transmission by blood getting into nasal membrane from shared snorting items • Crack use: at least one study (Schaefer) found higher rate of HCV in non-injecting crack users who indicated cracked, bleeding or burned lips • Personal items with blood on them: anything that cuts/breaks the skin or membrane (razor, clippers)

  11. Sources of Infection forPersons with Hepatitis C Injecting drug use 60% Sexual 15% Transfusion 10% (before screening) Other* 5% Unknown 10% *Nosocomial; Health-care work; Perinatal Source: Centers for Disease Control and Prevention Source: Sentinel Counties, CDC

  12. HAV HBV HCV HIV Acute infections Average/year* 93,000 78,000 25,000 40,000 Fulminant deaths/year 100 150 ? Chronic 0 1-1.25 2.7 infections million million Deaths/year (chronic) 0 5,000 8-10,000 15,000 * Based on estimated 2001 annual incidence. Estimates of Acute and Chronic Disease Burden for Viral Hepatitis, HIV, United States

  13. Hepatitis D and Hepatitis E HDV: • Coined “Delta Hepatitis” • Rarely seen in the United States • Found only in persons infected with HBV and has similar routes of transmission as HBV • Prevention is vaccination for HBV HEV: • Primarily a disease of import • Very similar to hepatitis A with fecal-oral transmission • Transmitted like HAV with the same symptoms • No vaccination available

  14. Meth and Viral Hepatitis • Little research on meth/viral hepatitis. PubMed search: HIV/meth = 213 abstracts and HCV/meth = 26 abstracts • Documented outbreaks of HAV and HBV in meth users • Hepatitis A - feces can be on pipes etc. • Hepatitis B - transmitted like HIV so similar links • Hepatitis C - IDU but what about bloodier sex? Blood into open wounds (incl. Nose/mouth)? • Scheinmann, R. et al., Non-injection drug use and Hepatitis C Virus: A systematic review, Drug and Alcohol Dependence (2006)

  15. Vaccinate against hepatitis A and hepatitis B If no access to vaccine: Wash hands! Prevent fecal matter from entering mouth Use barriers for oral/anal sex Clean sex toys between use Prevent blood, semen and vaginal fluids from entering body Avoid blood exposure: New syringe, cooker, cotton etc. every time for injection Use universal precautions Don’t share personal items that may contain blood (toothbrush/razor) Hydration and lubricants Cover open cuts/wounds Ensure instruments used for tattoos, piercing, acupuncture are new or sterilized Prevention of Viral Hepatitis Viral hepatitis prevention methods include HIV prevention but HIV prevention methods don’t necessarily prevent viral hep.

  16. Hepatitis A vaccine began usage in 1995 Two dose series at 0 and 6-18 months Hepatitis B vaccine began usage in 1982 Usually three dose series at 0, 1 and 6 months No severe adverse reactions. Most common side effects include site of injection soreness, headache, malaise Combination vaccine available called TWINRIX Hepatitis A and Hepatitis BVaccines

  17. Recommendations for Hepatitis A Vaccine • Injection and non-injection drug users • Men who have sex with men (MSM) • Travelers to HAV endemic countries • Persons with chronic liver disease • Persons with clotting-factor disorders • Children living in communities with historically increased rates of hepatitis A • Household and sex contacts of HAV+ persons • (People living with HIV – not a formal rec. but should be!)

  18. Recommendations for Hepatitis B Vaccine • Men who have sex with men • Persons with more than one sex partner in a six month period • Persons diagnosed recently with an STD • Sex contacts of infected persons • Injection drug users • Household contacts of chronically infected persons • Infants born to infected mothers • Infants/children of immigrants from areas with high HBV rates • Health care and public safety workers • Hemodialysis patients • Developmentally disabled in long-term care settings • People living with HIV

  19. New Hepatitis B Immunization Recommendations “A Comprehensive Immunization Strategy to Eliminate Transmission of Hepatitis B Virus Infection in the U.S.” MMWR Dec. 8, 2006. Vol. 55 No. RR-16 • Venue-based immunizations: all persons should be vaccinated in STD/HIV sites, drug treatment programs, correctional settings and clinics that see large amounts of IDU or MSM • Recommends all unvaccinated adults at-risk should be vaccinated • All adults who ask for vaccine should be immunized without having to self-disclose risk

  20. Viral Hepatitis Testing

  21. HCV Testing Recommendations from CDC Test routinely based on risk for infection: • Ever injected drugs (even once) • Transfusions/organ transplants before 1992 • Selected medical conditions (chronic hemodialysis, elevated liver enzymes) • Received clotting factors before 1987 Test routinely based on a recognized exposure: • Healthcare or public safety workers after exposure to HCV-positive blood • Children born to HCV-positive women

  22. Routine testing of uncertain need: Recipients of transplanted tissue History of tattooing or body piercing History of multiple sex partners or STDs Long-term steady sex partners of HCV-positive persons Users of intranasal cocaine or other non-injection drugs Routine testing is not recommended: Health care and public safety workers Pregnant women Household contacts of HCV-positive persons General population HCV Testing Recommendations from CDC

  23. Chronic Hepatitis B and C • Top causes of liver cancer and liver transplant • Symptoms include fatigue,depression,loss of appetite, nausea/indigestion,muscle/joint pain,mood swings, abdominal pain, fever, vomiting,jaundice,cognitive dysfunction,fluid retention,lack of concentration • Slowly progresses over decades (sometimes slow, fast, or little progression) often leading to liver damage • Monitoring important: liver, imaging, diagnostic tests • Drug-based and complimentary therapies available for both hepatitis B and hepatitis C

  24. Chronic Hepatitis C • Factors promoting HCV progression: • alcohol intake • age >40 at time of infection • HIV or HBV co-infection • male gender • Vaccinate for HAV/HBV when appropriate • Not everyone needs drug-based therapies • Liver and self-care essential • Emotional support, empowerment and education

  25. Drug-based Therapies for HCV • Medications to treat HCV: • Interferon (injected 3x week): an immune booster • Pegylated Interferon (injected 1x week): interferon w/ protein • Ribavirin (pill several times a day): an antiviral • Standard of care is combination therapy for 24-48 weeks, depending on genotype (type 1=48 weeks) • Effectiveness varies from about 40-80% (type 1 is hard to treat and ~40% of type 1 has sustained response) • Treatment can have many side effects like fatigue, depression, aches, hair loss and nausea • Treatment is expensive ($25,000 + a year) • Many drug users are denied access despite federal guidance otherwise

  26. HIV and Hepatitis C • Liver disease is #1 cause of death and hospitalizations in people living with HIV • Up to 1/3 of those living with HIV also have HCV (1/10 of those with HCV have HIV) • HIV infection may promote HCV disease progression (and sometimes vice versa) • Anti-HIV medications may cause hepatitis – especially in those with viral hepatitis • HCV treatment in HIV+ becoming more effective • HIV may impact HCV transmission (sex/perinatal)

  27. Integrate Viral Hepatitis!If We Don’t, Who Will? • Researchers: test for hepatitis B and C, ask about knowledge of serostatus, add hepatitis risks to surveys etc. • Front line staff: comprehensive disease model approach based on identified risks • Programs: include hepatitis questions on intake forms, risk assessments, case management forms, client surveys etc. • Advocates: CDC DVH budget less than 20 million - we need a funded national response!

  28. Do You Know Your Hepatitis C Coordinator? • Most states and several major cities (NYC, Chicago, Philly, D.C.) have CDC-funded Hepatitis C Coordinators • While HCV Coords may or may not have $$, they can provide data, presentations, brochures and other resources and want to collaborate with you! • http://www.cdc.gov/ncidod/diseases/hepatitis/resource/coordinators.htm • National Alliance of State and Territorial AIDS Directors (NASTAD) viral hepatitis working group, advocacy etc. www.nastad.org

  29. Viral Hepatitis Resources • Guidelines: NIH Consensus Statement on Hepatitis C, AASLD treatment guidelines, EASL and VA HIV/HCV treatment guidelines • Strategic Plans: National Viral Hepatitis Roundtable “A Call to Action: Eliminating Viral Hepatitis” (many states also have plans) • Websites: www.hcvadvocate.org, www.natap.org, www.hivandhepatitis.com, www.hepcnetwork.org, www.hepcproject.org

  30. ABCs of Viral Hepatitis

  31. People who have injected drugs and other substances (hormones, steroids, vitamins): Test for hepatitis C Get vaccinated against hepatitis A and B People who use non-injection drugs: Get vaccinated against hepatitis A Maybe test for hepatitis C (depends on blood risk – with meth for example) Men who have sex with Men: Get vaccinated against hepatitis A and B People living with HIV: Get vaccinated against hepatitis A and B Test for hepatitis C People with multiple sex partners or recent STD: Get vaccinated against hepatitis B People born in countries in Asia, Africa or the Pacific: Get tested for hepatitis B Transgenders: Get vaccinated against hepatitis A and B Test for hepatitis C if injected hormones Recommendations for Viral Hepatitis Testing and Vaccinations
