When it comes to hepatitis, doctors, like children, must learn their ABCs. As they have long been taught, the liver-destroying disease is caused by two distinct viruses, known as A and B. But many patients show no signs of having been exposed to either virus. Earlier this year scientists took a significant step toward solving the riddle of non-A, non-B hepatitis by moving on down the alphabet. They identified a third virus that produces hepatitis and called it type C. Last week researchers announced another milestone: the first effective therapy for hepatitis...
Hepatitis C afflicts an estimated 150,000 Americans each year. The virus, like type B, is spread primarily by sexual activity and through tainted blood in transfusions or on addicts' dirty needles. (Hepatitis A is passed along mainly through contaminated foods.) Researchers at Chiron Corp., a biotechnology firm in Emeryville, Calif., that first identified the C virus, have devised a test for the pathogen that can be used to screen the blood supply...
...Typhoid Mary, they become silent carriers of the disease. About half those infected eventually suffer liver damage. Some 15,000 patients a year develop cirrhosis, and a small number may get cancer. That toll may be cut by interferon. But doctors warn that the mystery of non-A, non-B hepatitis may not be completely resolved. Type C virus could account for most of these cases, but there is evidence that yet another blood-borne virus will extend the hepatitis alphabet still further...
