HBV Prevention Get vaccinated Do not share needles or works Safer sex Standard safety precautions Do not share personal items HBV-infected mother-to-child intervention www.hcvadvocate.org
Chronic HBV Chronic ~5-6% Adults – 90% Infants *These drugs are recommended as first line of treatment www.hcvadvocate.org
HCV Transmission / Prevention Hepatitis C is spread by blood-to-blood contact HCV is the most common blood-borne pathogen in U.S. www.hcvadvocate.org
HCV Survival • Hepatitis C virus lives on surfaces for up to 6 weeks • In syringes up to 63 days • Commercially available disinfectants kill HCV • Collected shared swabs – ~ 83% tested positive for HCV • HCV detected in used water for greater than 3 weeks • In bottles – HCV RNA detected even after rinsing out – plastic and aluminum retained HCV RNA longer • ~10% of filters wrapped in foil had HCV RNA after 24 and 48 hours www.hcvadvocate.org
Transmission/Prevention Sharing needles and drug preparation tools Blood products & solid organ transplantation before July 1992 Clotting factors before inactivation in 1987 Sexual transmission (0-3%) Mother-to-child (~4-10%) Healthcare workers (~2%) Hemodialysis www.hcvadvocate.org
Possible Transmission Routes • Tattoo & piercing* • Personal care salons • Shared household (hygiene) items • Coke/crank straws & crack/meth pipes • 10% of routes can not be identified * Higher in unsafe non-commercial settings: prisons/mental institutions/on the streets/home grown www.hcvadvocate.org
Safer Tattoos – www.hepatitistattoos.org Version 17.5 www.hcvadvocate.org
Little or no data……. • Dental and other procedures before universal precautions • Jet gun injections • Transgender people • Sharing needles and re-assignment surgeries www.hcvadvocate.org
HCV is Not Spread by: Breast feeding Food or water Sharing eating utensils or drinking glasses Sneezing Hugging *Not spread by casual contact* www.hcvadvocate.org
Prevention: Do not share anything: Needles, cookers, cotton, tourniquets, water, water containers, etc. – Wash hands www.hcvadvocate.org
Prevention – more • Do not share non-injection drug equipment • Coke/crank straws • Crack/Meth pipes • Tattoo / Piercing • Sterilization, autoclave, separate ink pot, new needles www.hcvadvocate.org
Prevention – more Sexual: 0-3% – monogamous partners– counsel Safer sex – additional risk through sex: Multiple partners Coinfection with HIV or HBV Having herpes, lesions, sores, open cuts, wounds Sexually transmitted diseases Mother-to-child www.hcvadvocate.org
More Prevention • Health care workers • bloodborne pathogen protection • Razors / toothbrushes covered • Cover all wounds • Transfusions – estimated that less than one per 2 million transfused units of blood tainted with HCV • People with HCV: Do not donate blood, sperm, eggs or organs – EXCEPTIONS….. www.hcvadvocate.org
Lifecycle • Single-stranded RNA virus • Mainly infects liver cells—but also found in other cells of the body • Cell culture discovered and available www.hcvadvocate.org
HCV Diagnostic Tools Hcv Identified in 1989 Important: Interpretation of test results and decisions about healthcare are a collaboration between a medical provider and a patient www.hcvadvocate.org www.hcvadvocate.org
Baby Boomers Account for the Majority of HCV Cases in United States Estimated Prevalence by Age Group 1.6 Number With Chronic HCV Infection (millions) 1.4 1.2 1.0 0.8 0.6 0.4 0.2 0 1990+ 1980s <1920 1920s 1970s 1940s 1950s 1930s 1960s Birth Year Group www.hcvadvocate.org
Increased Diagnosis and Treatment The Tipping Point? Aged-Based Testing OraQuick HCV Antibody Test Newly FDA-Approved Antivirals Templates • Cure rates up to 90% • In Development • Approval estimated – end of 2014 • Interferon-free therapies will mean that almost everyone will want to be treated The Centers for Disease Control (CDC) & the United States Preventive Services Task Force (USPSTF) have recommended a one-time test for persons born between 1945 and 1965 >800,000 people • Finger Prick & Whole Blood Draw FDA Approved • Results available within 20 minutes • More testing within clinics and mobile sites can lead to increased consultations about care, management and treatment Version 17.5 www.hcvadvocate.org
HCV Antibody Tests HCV Elisa III (EIA), CIA: Detects antibodies Signal to cut off ratio = 95% chance true antibody positive Home Access test kit Window period – 2-26 weeks www.hcvadvocate.org
OraQuick HCV Rapid Antibody Test Finger Prick & whole blood: FDA and CLIA Waiver approved – 2011 www.hcvadvocate.org
HCV RNA – Viral Load • PCR (polymerase chain reaction) – lowest range • TMA (transcription mediated amplification) – lowest range • DNA (bDNA) assay – highest range • Amount of virus per milliliter of blood • International units • Low – less than 800,000 IU/mL • High – more than 800,000 IU/mL www.hcvadvocate.org
How is Viral Load Used? Confirm active infection Soft predictor of treatment response Confirm HCV medications are working Dictate treatment duration for some HCV Medications ***Does Not Correlate with Disease Progression*** www.hcvadvocate.org
Genotype & Quasi-species • Seven major genotypes (plus sub-types) • Genotypes numbered 1, 2, 3, 4, 5, 6, 7* (1a, 1b, etc.) • Genotype 1 – 70% of US population with HCV • Genotypes 2, 3 – 30% of US population with HCV • Quasi-species • High error prone virus – mutates quickly * Discovered in 2013 www.hcvadvocate.org
Liver Tests ALT: a non-specific marker of liver inflammation Not a good test to monitor people with HCV AST, AP, GGT, bilirubin, platelet, prothrombin time (PT) www.hcvadvocate.org
Liver Biopsy *Measures liver health *Treatment decisions** *Benchmark Note: Fewer biopsies are being performed because of newer therapies with cure rates > 90% and the use of the Fibroscan Metavir Scoring System – 0, 1, 2, 3, 4 No activity Severe activity www.hcvadvocate.org
FIBROSCAN FDA Approved – April 2013 Imaging technology that uses a sonogram to measure the speed of sound waves directed through the liver to measure stiffness Measures either minimal damage or severe damage Version 17.5 www.hcvadvocate.org
