Hepatitis C is the most common blood-borne infection in the U.S. Approximately 2.7 million Americans are infected. Transmission of the virus occurs through contaminated blood through such activities as blood transfusion before 1991, intravenous drug use, occupational exposure, sexual contact, and possibly intranasal drug use, tattoos or body piercings.
Most people have no symptoms and are surprised when they are informed of the diagnosis. Abnormal lab tests during routine physical examination, insurance applications or blood donations often prompt the hepatitis C investigation. People with symptoms most commonly have fatigue, muscle and joint pains, and right upper quadrant discomfort.
The virus is diagnosed by blood tests. The most common screening test detects the hepatitis C antibody. If this test is positive, it means there has been past exposure to the virus (only rarely is the test falsely positive). Most people exposed to the virus have a chronic infection, as our body does not eradicate the virus by its own defenses very well.
Blood tests performed to confirm current presence of the virus are called polymerase chain reaction (PCR) tests. This method is sensitive to detect the virus, determine the genotype and quantify the viral level. The genotype and viral level do not correlate with the severity of infection. In this part of the country, most people have genotype 1 (75%), followed by genotype 2 (15%) and genotype 3 (10%). Genotype 4 is most common in North Africa and the Mediterranean. Genotype 6 is found in East Asia.
If testing confirms the virus is present, the next important step is proper evaluation of liver damage. The initial testing involves lab work to measure liver function and other tests that can give pieces of information about the severity of fibrosis (scarring). In some instances a liver biopsy or special type of MRI is indicated to clarify the severity of damage. Even after many decades of infection, hepatitis may not cause much liver injury. The amount of damage is an important guide to determine if treatment is necessary.
The world of hepatitis C treatment is changing rapidly. Over the next couple years newer medications will be coming that are more effective to eradicate the virus, fewer side effects and shorter length of treatment. It is anticipated the treatments will be remarkably better than the present treatments. This makes it very important to have evaluation if hepatitis C has been diagnosed.
Recommendations for living with Hepatitis C
Diet: There is no particular diet that must be followed. Protein is commonly misconceived as being harmful to the liver, but does not need to be avoided. Vitamin supplements are not necessary if a well-balanced diet is consumed. If vitamins are used, they should not contain additional iron. There is no research evidence that natural or herbal remedies fight the virus or preserve liver function. Safety of many of these products has not been established. Over-the-counter products such as acetaminophen (Tylenol), ibuprofen, and aspirin can be used in recommended doses.
Alcohol: Alcohol is the one chemical known to alter the course of the hepatitis C virus. Alcohol has been shown to speed the rate of liver damage with hepatitis C. Unfortunately, it is not known what a safe amount per day or week is. If some alcohol easily leads to more alcohol, it may be best to abstain altogether.
Daily living: Hepatitis C is spread through contaminated blood, so cover open wounds and disinfect spilled blood. Do not share personal hygiene items such as razors and toothbrushes. The virus is rarely spread through sexual contact, however condoms are recommended as a precaution. If your partner is concerned, they can be tested. If a person with hepatitis C is in a long-term monogamous relationship, no special preventative precautions need to be used in sexual relations.
Vaccination: Vaccination for hepatitis A and hepatitis B are recommended if you are not immune. You are at no higher risk for hepatitis A and hepatitis B, but it would be more serious for your liver if you contract these viruses.
