  • "My name is Peter Grayson and right now we're at the National Institutes of Health which

  • is Building 1 which is the clinical center where we take care of patients under research

  • protocols at the NIH. So I'm focused on combating the disease known as vasculitis which is a

  • family of rare diseases that are characterized by inflammation inside of blood vessels. And

  • these diseases can lead to life-threatening outcomes for patients.

  • So I grew up in Charleston, South Carolina. It wasn't something that I thought I was going

  • to be a scientist from the get-go, from birth. I wanted to be a musician and spent some time

  • playing in rock n roll bands around the country and then kind of meandered my way into medicine

  • and came at it much later in life.

  • So vasculitis, among doctors it's a scary disease. It's one that many doctors don't

  • know anything about because it's quite mysterious. Wherever you have blood vessels, you can have

  • a problem and you have blood vessels throughout your entire body. So you can get a lot of

  • bizarre symptoms. And typically what happens to a patient is they get something where they

  • got a painful red eye and then they lose sensation in their foot. And then they start coughing

  • up blood, and then all these crazy, bizarre things happen in sequential order.

  • They go see millions of different specialists. There's a long delay and finally somebody

  • will put the pieces together and realize that this is a vasculitis. And we have made a lot

  • of progress in the last 20 years. It used to be that these diseases would kill you with

  • a few months of contracting them, and now patients do not die from the diseases anymore.

  • And we're faced with a whole new challenges of managing these diseases if they turn into

  • long-term illnesses.

  • So this is the heart and your aorta is this big tube that comes off the heart and comes

  • down here and splits into the blood vessels of your legs. These are the blood vessels

  • of your arms and these are neck blood vessels going up to your brain.

  • For patients that have a type of vasculitis called large vessel vasculitis, they can have

  • problems and disease in the big blood vessel of their body.

  • And so if vasculitis affects a big blood vessel known as your aorta, it can cause it to swell

  • up and form an aneurysm. It can cause things to close down and form blockages. And so a

  • patient will come in and they'll have no blood pressure in their right arm or no pulse in

  • their left leg. We can comprehensively image all the blood vessels in their body.

  • And we do these kinds of imaging studies and figure out where in their vasculature there's

  • disease. Where we are with these diseases is that people survive them but they relapse

  • and they relapse unpredictably. And so we're trying to figure out things that allow us

  • to predict what happens over time. So you're trying to actually figure out something within

  • an individual patient that you can target treatments to.

  • And I think in that setting this is kind of a new age of discovery in medicine. Before

  • we used to be limited with what we could see or a couple of simple blood tests we can do,

  • but now we're not constrained by hypotheses and by what people have done before us. You

  • can actually really in an agnostic fashion, yes categorize what's happening at a cellular

  • level.

  • [British guy] Wait a little bit longer. The IV contrast gets excreted by the kidneys.

  • The way things are right now, there's so many different aspects of research that are going

  • on that you can't know everything. But it's great if you're sitting at a table where you

  • have representations from all the different kinds.

  • When you're in medical school, they tell you that 50 percent of what you learn in five

  • years is wrong, and that's kind of daunting because you're sitting there trying to study

  • and take all this in and you're trying to figure out which half you really need to know.

  • But what that means and why that's really cool is because we're rewriting medical history

  • continuously, you have the opportunity in medicine and medical research to change the

  • textbooks and to change the course of medical history in a very short time. And that's what

  • conceptually that really excites me.

  • If you find something that's surprising and interesting, it opens up a whole new box and

  • you go down this tunnel and there you're off and running and doing a totally different

  • thing than you were doing the day before. And that aspect of the job is great. It's

  • extremely challenging. It's constantly shifting. There's constantly interacting with new people

  • who are bringing in new ideas. You just don't know what the next day's going to be and that's

  • really, really fun.

  • Really, the journey is the destination. I mean you just have to stop thinking about

  • where you're going to be and what milestones you're going to hit in your career and just

  • enjoy the ride because it's a really incredible experience. Once you relax and realize that

  • you know you're in a very fluid field, that sort of rewards creativity and rewards hard

  • work, and it takes you into just unexpected places, I think we're often trained to want

  • to hit milestones in our lives.

  • And once you sort of let go of that a little bit, I think you realize how exciting this

  • career is."
