...President, you promised us a clean administration--clean planet, clean schools, clean government. After 100 days, what do we have? An oil slick in Alaska, blood-stained streets in Anacostia and mud-spattered reputations in the government, your government...
Many people who get blood transfusions these days are understandably nervous. Transfusions have saved countless lives, but they have sometimes transmitted serious blood-borne diseases, including AIDS. While public health officials point out that careful testing has all but eradicated the AIDS virus from the blood supply, they have not been able to claim that transfusions are perfectly safe. Reason: about 5% of patients who receive transfusions are exposed to a virus that can cause a potentially deadly liver infection called non-A, non-B hepatitis...
...population harbors non-A, non-B viruses. The majority of those who are exposed show no symptoms, but of the patients who come down with chronic liver disease, an estimated 10% die within five years. About 150,000 new infections occur each year because of blood transfusions...
This last major threat in the U.S. blood supply may soon be greatly reduced. After six years of research, scientists at Chiron, a genetic-engineering firm in Emeryville, Calif., have developed a test for the presence of a non-A, non- B hepatitis virus in blood samples. According to papers published last week in the journal Science, trials have shown that Chiron's test is highly reliable. It can now help eliminate the virus from the blood supply. The inexpensive test (about $2 per blood sample) is expected to be approved by the Food and Drug Administration this year...
Chiron's initial breakthrough was to isolate a viral protein from blood samples taken from patients with non-A, non-B hepatitis. By cloning large quantities of the protein, the company was able to develop a test to detect its presence in blood. Chiron called the pathogen the "hepatitis-C virus." In clinical studies done at the National Institutes of Health, the Centers for Disease Control and laboratories in Italy and Japan, blood samples from patients thought to have non-A, non-B hepatitis were screened using Chiron's test. At least 80% of the samples tested positive...
