If you are tired, feel sick and have muscle and joint pains, part of your evaluation should include a blood test for hepatitis C, even if all liver function tests are normal (1). Untreated, hepatitis C causes death from liver failure and cancer (2,3) within 30 years or can cause heart attacks earlier than that (4). Hepatitis C affect the entire body, not just the liver (5), makes you feel sick and miserable (6), and causes such severe muscle and joint pain and a positive rheumatoid factor that some people with hepatitis C are diagnosed with rheumatoid arthritis (7). It also can cause severe nerve damage called Guillain-Barre syndrome (8). You can become infected with this virus from needles, transfusions, and sometimes from sex (9) and sometimes no source is found.
More than 4 million Americans get hepatitis C from infected needles or blood transfusions, and each year, more than 10,000 Americans die from it. More than 90% of those who have untreated hepatitis C will carry the virus forever. It can take more than 15 years to develop signs of liver damage, 19 years to suffer permanent liver damage called cirrhosis and 26 years to develop liver cancer (2,3). Hepatitis C is the most common cause of liver cancer in North America (10) and interferon can prevent liver cancer in patients with hepatitis C (11,20). The usual treatment is to give yourself three injections a week of interferon for 6 months, which helps to prevent liver cancer, but it returns liver tests to normal only 50% of the time and gets rid of the virus in only 20% (9).
A study from Baylor Medical School in Houston showed that pegylated interferon alpha 2-b injections and ribavirin pills clear the hepatitis C virus from the blood in 61 percent of patients and improve liver function in most patients. Forty-eight weeks of weekly self injections of pegylated interferon and daily ribavirin pills were used. The pegylated interferon stays in the body longer than regular interferon and requires less frequent injections. This treatment was not offered to people whose livers are severely damaged, who abuse alcohol or drugs or suffer from severe uncontrolled psychiatric illness. The most common side effects are flu-like symptoms, fever, fatigue, nausea, headache, poor appetite, and anxiety or depression.
Other studies show that 76 percent of people with hepatitis C can be cured with injections of 3 million units of interferon three times a week and ribavirin for 24 weeks (12,13). Ribavirin alone may even afford a cure (19). Starting treatment early in disease may afford a higher cure rate (18). Those who clear virus early in treatment are the ones most likely to be cured (14). A blood test called hepatitis C RNA can be used to measure the amount of hepatitis C virus in your bloodstream. You can usually tell if 6 months of interferon will cure by measuring your viral load after one month of treatment (15). If you still have the virus after six months, you should be treated for a longer period of time (16). Hepatitis C has a low rate of transmission between spouses (17).
