Scientists say they’ve found a big reason why treatment for chronic hepatitis C infection works better for White patients than for
People with a certain gene variant are far more likely to respond to treatment, and that variant is more common in people with European ancestry than
In fact, that probably explains about half the racial disparity in treatment response, the scientists estimate in a study published online Sunday by the journal Nature.
The work involved 1,137 patients who had a chronic infection with the most common type of hepatitis C virus found in the United States and Europe, one that is less responsive to treatment than other types. They were given standard drug treatment.
Analysis showed the treatment wiped out the virus in about 80 percent of study participants with the favorable genetic variant, compared to only about 30 percent among those who lacked it.
