STEVE INSKEEP, HOST:
And now let's continue Your Health with a report on a deadly infection which up to four million Americans have, although most don't know. It's a virus called Hepatitis C. It is a leading cause of liver failure and liver cancer, but there is hope.
NPR's Richard Knox tells us about new treatments that can cure the majority of those infected.
RICHARD KNOX, BYLINE: More than three years ago, Nancy Turner went to the doctor with some unspecific symptoms.
NANCY TURNER: Nothing really spectacular. I was feeling a little bit more tired. Just like kind of upset tummy type thing and just chalked it up to stress from work and being busy.
KNOX: But tests revealed sky-high levels of the Hepatitis C virus in her blood.
TURNER: I was devastated.
KNOX: What was going through your mind when you found out?
TURNER: Oh, I - trying to figure out where I possibly could have gotten it.
KNOX: Turner is 58 - born in 1954. Two out of three Americans with hep-C are baby boomers. Many of them got it by experimenting with illicit drugs - either by injecting or by snorting. Either way, the virus can get directly into the bloodstream, the only way hepatitis C is transmitted.
You can't catch it by coughing, kissing or sharing a coffee cup. Some baby boomers got the virus from having a blood transfusion before 1992 when all donor blood began to be tested for hep-C.
David Thomas of Johns Hopkins Medical School says today infections are often discovered when somebody gives blood.
DR. DAVID THOMAS: You go back and talk to them, more than half of them will say, well, yeah, I mean, of course, when I was in high school I, you know, messed around a little bit, but I'm not a drug user. And so that's the kind of thing that really drove hepatitis C and expanded hepatitis C in our population back in the '60s and '70s.
KNOX: Nancy Turner says she smoked a little marijuana back then, but never experimented with other drugs. But she is a nurse, and health care workers are at higher risk of catching hep-C from being stuck with contaminated needles or having any break in the skin.
Turner doesn't recall any such incident. And like 30 percent of hep-C patients, she may never know the source of her infection. She went on the standard treatment. Soon her life was disrupted by the side effects - severe fatigue, depression and other problems.
TURNER: It was a long, tough road.
KNOX: But she was determined to beat the virus. And at first the treatment seemed to work.
TURNER: I did a year treatment and at that time there was no more hep-C virus that was evident. I went back for my three-month blood work, it had come back full force. Most discouraging day of my life.
KNOX: But last year, two new drugs got approved for hep-C, so she tried one of those, along with the older drugs. The new regimen was even tougher. Turner suffered severe rashes and other side effects, including a total loss of appetite. She lost 60 pounds.
Kathleen Coleman helped her get through it. She's a nurse practitioner at Tufts Medical Center in Boston.
KATHLEEN COLEMAN: We can get them through therapy. We do manage the nausea, we do manage the anemia, we do manage the rash - in a way that's at least enough to help the patient get through.
KNOX: And once again, the treatment seemed to work. Tests indicated the virus was rapidly cleared from Turner's blood, as it is for most patients these days.
COLEMAN: We're going from 35, 40 percent, you know, clearance rates to 70, 80, 90 percent clearance rates. That is a tremendous change.
KNOX: And that's why the Centers for Disease Control and Prevention is urging everybody born between 1945 and 1965 to get tested for hep-C because most of them can now be cured.
It's been three months since Turner completed her latest round of treatment. I caught up with her during a checkup with Coleman.
COLEMAN: How are you?
TURNER: I actually have been wonderful since the treatment stopped.
KNOX: Coleman runs through the list of symptoms.
COLEMAN: So completely recovered? Like no more shortness of breath, no rash?
TURNER: Absolutely nothing.
COLEMAN: No itching, no nothing?
KNOX: It's all good. But Turner brings up the most important thing.
TURNER: My appetite is back, which is like, oh.
TURNER: I mean, food tastes wonderful again. I think that's my favorite part of this whole thing.
KNOX: But the real test is whether the virus doesn't show up in her blood months after treatment stops.
TURNER: Either it's going to be cured or it's not. So, I'm kind of, you know, walking a little bit on eggshells waiting for that last blood test.
KNOX: Recently, she got the results. The virus has roared back. So she's among the 20 percent or so who aren't cured by the latest drugs. But that's not the end of the story. There are a couple of dozen new drugs in the pipeline. Nancy Turner might still be cured by one of those - and maybe with a lot fewer side effects.
