NIDA AIDS Research Program

A NIH-funded study, published February 19 in the Annals of Internal Medicine, shows that possessing either of two specific gene variants make it more likely that a patient’s own immune system can successfully fight off hepatitis C infection (i.e., without the need for medications). Furthermore, if a person possesses both, the chances of clearing the virus are even greater. These results may predict which patients will respond more favorably to hepatitis C treatment.
