African Americans and Hepatitis C Marlene Taylor PA-C HIV/HCV Primary Care Provider Montefiore Medical Center
African Americans are twice as likely to be infected with the hepatitis C virus (HCV) compared to the general U.S. population, according to the CDC. While African Americans represent only 12 percent of the U.S. population, they make up roughly 22 percent of the estimated 3.2 million persons with chronic HCV infection. Moreover, chronic liver disease, often hepatitis C-related, is a leading cause of death among African Americans ages 45-64.
Hepatitis C Facts • Hepatitis C is a liver disease caused by a virus. • Hepatitis C is usually spread when blood from a person infected with the hepatitis C virus enters the body of someone who is not infected. This can happen from sharing equipment for injecting drugs, receiving blood transfusions or organ transplants before 1992, getting a needlestick injury in health care settings, and even being born to a mother who has Hepatitis C. And some people don’t know how they got infected. Hepatitis C can spread through sexual intercourse, but it’s rare. • Anyone can get hepatitis C, but African Americans – as well as people born between 1945-1965, (“babyboomers” )– bear a disproportionate burden of disease.
Hepatitis C Facts • Most people living with hepatitis C do not know they are infected. • The hepatitis C virus (HCV) can cause chronic hepatitis, in which the infection is prolonged, sometimes lifelong. Chronic hepatitis can lead to cirrhosis, liver failure, and liver cancer. In fact, viral hepatitis is the leading cause of liver cancer and the most common reason for liver transplantation. • Most people living with HCV infection often have no symptoms until significant damage has been done. • There is no vaccine to prevent hepatitis C infection. • Getting tested is the only way to know if you have been exposed to hepatitis C. • There are new and improved treatments exists for hepatitis C.
Features of Hepatitis C Virus Infection Incubation period Average 6-7 weeks Range 2-26 weeks Acute illness (jaundice) Mild (<20%) Chronic infection 75%-85% Cirrhosis 10%-20% Mortality from CLD 1%-5% Liver Cancer 1%
Serologic Pattern of Acute HCV Infection with Progression to Chronic Infection anti-HCV Symptoms +/- HCV RNA Titer ALT Normal 3 3 6 1 2 4 0 1 2 4 5 Months Years Time after Exposure
Transmission of HCV • Injecting drug use • Blood Transfusion, transplant from infected donor,(before screening available in 1992 ) • Therapeutic (contaminated equipment, unsafe injection practices) • Occupational (needlestick) • Perinatal (mother to child) • Sexual • Sharing Contaminated items with infected blood( ie toothbrush, razor, )
Signs and Symptoms • Persons with newly acquired HCV infection usually are asymptomatic or have mild symptoms that are unlikely to prompt a visit to a health care professional. When symptoms occur, they can include • Fever • Fatigue • Dark urine • Clay-colored stool • Abdominal pain • Loss of appetite • Nausea • Vomiting • Joint pain • Jaundice
Signs and Symptoms Most persons with chronic HCV infection are asymptomatic. However, many have chronic liver disease, which can range from mild to severe, including cirrhosis and liver cancer. Chronic liver disease in HCV-infected persons is usually insidious, progressing slowly without any signs or symptoms for several decades. In fact, HCV infection is often not recognized until asymptomatic persons are identified as HCV-positive when screened for blood donation or when elevated alanine aminotransferase (ALT, a liver enzyme) levels are detected during routine examinations.

Challenges • Genotype • Fewer Blacks in Clinical trials • Stigma • Co morbid conditions • Neutropenia • Disease progression (Fibrosis) • Treatment Response • IL28B • Access to care/ Insurance/
Treatment • Important to understand that currently available treatment must be individualized –(treatment experienced or naïve, genotype, liver bx etc) • Early 2000-Combination therapy Pegylated interferon, and ribavirin, • 2011 in addition to the above two protease drugs (Bocepravir or Telapravir FDA approved and one combined with peg and riba for treatment, • Studies show that currently available treatment improved because of shorter duration • Better clincal outcomes (SVR’s) • Improved tolerability, less side effects • Treatment is defined as undetectable HCV RNA in the patient's blood 24 weeks after the end of treatment • At least six distinct HCV genotypes (genotypes 1–6) and more than 50 subtypes have been identified. Genotype 1 is the most common HCV genotype in the United States and the most common in African Americans. • Patients with genotypes 2 and 3 are almost three times more likely than patients with genotype 1 to respond to therapy

Questions • What is the diagnosis in this patient? • What was the most likely mode of transmission? • What are the next diagnostic steps in her medical work up? • Is she cleared to go to return to school? to work? • What would you advise this patient to do immediately? • Would you refer this patient to a specialist for treatment ? Why or why not? • What important information is missing in the history essential for the management of this patient?
Despite the seriousness of this health problem in the African American community, too few African Americans know about the disease or get tested for it. Early detection of chronic viral hepatitis infection can save lives,” observes Dr. Ronald Valdiserri, MD, MPH, Deputy Assistant Secretary for Health, Infectious Diseases and Director, Office of HIV/AIDS and Infectious Disease Policy at the U.S. Department of Health and Human Services
