Alpha Gal

Oh, wait, you're listening to Radio Lab. Radio Lab. WNYC. See?

Good. Is your mic on? Yeah, I'm getting nervous. I can be nervous.

Maybe I should get my iPad. Are you allergic to radio greatness? I know. I've been really exposed to it.

Yeah. Anyway, let's go. Are we rolling? We're rolling.

We're rolling. Okay. I'm Robert Goldch. This is Radio Lab.

Today we're going to begin with a conversation between Dan Pashman, a host of a podcast here at WNYC called The Sportfolds by Food. And Amy Burl. Amy Burl. Amy Burl.

Amy, which you never expected, certainly didn't want. And you can have any of us at any time. So, years ago for any of this happened to you, just tell me what was your relationship with meat? My relationship with meat.

Yeah. Well, you know how when you're little and your mom is like, you can have any special dinner for your birthday. My dinner was meatballs. And she was like, except meatballs are so hard to make, so it was pot roast.

And then Peter, you know, Peter, you know, Peter, you know, I used to go there quite often and I live there and I have a Peter, Peter, and a credit card. It was hard to get. You know, I don't know how they give them out, but nobody seems to have one. I don't think they give them out anymore.

I was very into Peter, like I was living in Williamsburg and it just opened at like one o'clock every day. You could just walk in at one, had an amazing bar. There's no tablecloth on the table. These old German waiters.

They bring out your porterhouse for three. They put a little plate upside down and then put the big platter on top of it so it's tilted and all the juice runs to the end. And then they like have the special double spoon thing that they somehow like scooped juice onto your steak. And oh, so good.

And also like the smell of burning fat from an hamburger. What a hot dog's. Oh my god. The hot dogs so much.

When you bite into them and they're like, I'm having like a snap. And like having a weenie roast out in the open air is just like, oh god, it's so good. Anyway, I was always very into meat. What changed?

Oh my god. It was terrible. It was what happened was I was having this beautiful springtime. I was having a beautiful leg of lamb with some neighbors and we like put it on the grill and it was just a delicious beautiful dinner.

And I had served with it some ramps that I foraged in my mom's yard by the way, just a wild onion. And so so we had this delicious meal and then I went home and I was going to sleep at like midnight like a few hours later and I just felt weird. I was like, oh god, something's wrong. I feel like really anxious.

Like something's wrong with me. And I went in the bathroom. I'm like, look in the mirror. And I was like, I kept laying down and be like, I'll just sleep it off whatever it is.

But every time I lay down I feel like I was going to faint. So I was like, prop myself up. And I was like, oh god, it's so terrible. Like stomach cramps.

It's just like a weird feeling of impending doom. You know, but just like anybody just like, just get a good night's sleep. That's a little water on my face. I mean, I don't think we think this but I thought like maybe a snail, a tiny snail was on one of the ramps that I ate and it was like poisoning me somehow.

You know, snails, I mean, they probably poisoned us. So I called my friends in the morning. I was like, hey, how you guys doing? How was dinner?

And they were like, oh, so great. So great. Nothing weird. No horrific panic attacks.

And they were like, oh, thank you so much for doing it again. And I was like, wow, I really had a rough night. And but I didn't think anything happened. I went on with my life, you know, just like whatever.

And then about a week or two later, I made some cheeseburgers. And I ate a cheeseburger. And I was watching good bye, Mr. Chips.

Really tear jerking movie and a good go up too. And about a couple of hours after I ate, I was like, starting to feel really weird. Again, I was like, I was like, I was like, I stand up. I was like, I think I'm a faint.

I really light head. I can't catch my breath. I feel like really woozy. I was like, oh my god, this is very similar.

I ran into the bathroom. And I was like, looking in the mirror and lo and behold, I had all of my stomach. And then they started coming out of my hands. And I was like, oh my god, something's happening.

And at one point I did get up and unlock my door because I did feel like I'm going to pass out calling ambulance. And they're not going to be able to get in. So I mean, I was a little bit afraid of what was happening. And I woke up in the morning.

The first time I did was Google, sudden meat allergy. So I was like, this seems like an allergy. And the only thing that was the same was meat. And I'm going through.

And like the second thing that came up was this article that was like Florida man has sudden meat allergy. And I was like, oh my god, I think it's a possible. I could have this. And so I made a point with my doctor.

I brought an article. I'm like, I'm going to be this person, but I can do it. I had the article in my pocket. I'm like, what?

What? What person? You know, the person goes like doctor with something. I found on the internet.

So I brought the article. It was in my pocket. And like, I got through the whole like checkup. And I was like, when I was paying the receptionist, I pulled it out and gave it to receptionist.

And I was like, could you give this to the doctor? So that was like the best I could do. And then I did call my doctor and had a conversation with him on the phone asking him if I could get tested. So some people think allergies are just like in your head.

This is science writer Peter Smith. We don't talk about them after we heard any story because Peter is an investigator of many things, including strange allergies. And people are like mushrooms hurt them or they think Wi-Fi hurts them. Wi-Fi hurts them.

I don't know. When I produced a lot of NASA and I got into the studio and we told him about any story he said. Yeah, all right. I know exactly who you need to talk to.

Yeah. Thomas Platt's Mills. Thomas Platt's Mills. That's right.

How are you? I'm very well. Dr. Platt's Mills is now at the University of Virginia in Charlottesville.

He's a professor and he works at an allergy clinic. We constantly sifting through stories, which not only you don't believe, but actually nonsense. And he told us in the last 10 years or so, he started hearing lots of stories just like him. Somebody shows up at the office convinced that they're allergic all of a sudden for no apparent reason to read me.

The first time I heard it was probably as early as 2004. And every single time he heard the story, he would tell the patient exactly what Amy's doctor told her. No, no, no. It's not possible.

Right. So what's wrong with these complaints in Orthodox medical way? Oh, everything. Adults don't become allergic to something they've eaten for 40 years out of the blue and certainly not read me.

So you're basically saying to these patients, I think you must be making this up because I can't explain it. I don't use language like that. I was trying to do your inner voice. Oh, you don't want to know what doctors are thinking in the inner voices.

You know, you're often thinking the middle of an interview. Is it possible that he's got, you know, some ghastly disease. The point is that when he hears a story like Amy's, he just didn't believe it. But then everything changed.

Thanks oddly enough to a cancer drug. This new cancer drug called Cetexum App. In New York today, Martha Stewart was indicted on criminal charges relating to the drug that got Martha Stewart in all that trouble for insider treating. Remember that?

I went to jail for six months. Anyway, very promising, exciting new drug. But then... Doctors were giving people this injection and it was looking up on the floor of the doctor's office.

In shock. Yeah, there'd be an anaphylactic shock. Their hearts would start beating faster. In the cramps, their immune system would start to overreact to something new and alien that came in with the drug.

Basically, a classic allergic reaction. So the mystery lands on Thomas Plasimals's desk. Yes. So we were asked to look at Cetexum App to see if they could figure out what was causing reaction.

And he does the two grips of blood control sample on the people that have this allergy. And he quickly zeroed in on a particular molecule, the sugar, that was per to the drug. This sugar, galitose, alpha 1, 3 galitose. Or alpha-gal.

Alpha-gal? Yeah. As in a particularly great lady? Yeah.

Better than the beta-gal. It's like alpha male, alpha female didn't quite have a ring to it. Anyway, it seemed like alpha-gal was the culprit. Yeah.

If you tell me four years earlier that there's a whole lot of people out there who are allergic to this sugar. I just thought you were smoking, you know, vaping again. Because not only does this sugar, alpha-gal show up in the cancer drug, and this is where you get back to Amy, it also shows up in the blood of mammals. All non-primite mammals.

So every time you eat lamb or beef goat, camel, even tripe or pigs, kidneys, you're also eating alpha-gal. So I'm reading this article and it says like, it's this thing called alpha-galactase or alpha-gal or whatever. So it made no sense that someone like Amy who had been eating me all her life would suddenly somehow be allergic to alpha-gal. I just was like, this was so stupid.

So one day. It's getting to be a barbecue season. I really have like a couple of barbecues where I just do a whole pork butt and a brisket and hang out all day doing it. And I was like, very wanted to do that.

And I was like, I'm just going to, not even, not even know. So I was like, forget my doctor will test me. I'm going to test myself. So I was going to be very careful.

I got a thing about a girl. And I was like, I'm not going to do it alone. I'll do it with my mom. My poor mom.

And so I went up to my mom's and she's like really into food. So she was like, oh, it's so exciting. I got two porterhouse cakes and say let's do's. Did you explain to her what you were testing?

Yeah, I did because I had talked a little bit about it with her. So like, fire up the grill, do the porterhouse. I even think I like Instagram does a joke. Like, ha, ha, ha.

This might be the last time you hear from me. But so, you know, we're having a nice summer day just me and my mom having our steak. I only ate like a couple of bites because I was slightly nervous. And I was like sitting in the grass with my dog and reading the book and trying to think like, do I feel normal?

Which try it folks? It's hard to figure out what you started asking yourself. Do I feel normal? Is this?

Am I breathing? Am I stomach heard? Something wrong? And I was like, oh, I feel pretty good.

And the neighbor came over and was like chatting with us and it was in the middle of that conversation where I was like, I kind of feel like I have to feel the bathroom. But maybe I just have to feel the bathroom. So I went to the bathroom. I was sitting there.

I was like, oh, God, something feels bad. And then I was like, oh, God, I definitely, this is not right. Something's wrong. And I went in to get the Benadryl and I took the Benadryl and I went to my bedroom.

And I was sitting there. I was like, whoa, I just feel right. Maybe I just take a deep breath. I'll just stand up.

Maybe I'll just put my hands over my head like this. Oh, that feels slightly better. I think. And then I was finally like, I think we should go to the hospital.

And I went outside. I was like, mom, I think after driving to the hospital. She was like, what? Oh, my God.

I'm going to go change my clothes. Change my clothes. She's not wearing my hospital level clothes. So I'm like, okay, hurry up, mom.

Are you ready, mom? And then I was like, while she changed her clothes. I suddenly was like, oh, my God. Got my wallet out of my cell phone.

And I threw it towards my hospital bedroom door. And I was like, it's my insurance card. Call an ambulance. And I just hit the floor.

Eventually, the ambulance arrives. I got stabilized. I was strapped to the thing. I was in the emergency room.

They were shooting me full of, I don't know what I've been ever in adrenaline. And the little 12-year-old emergency room doctor runs in. I was like, I locked it up on the internet. Alpha-gal.

Fascinating. What? That's terrible. I'm never.

That could be true. That's true. Then I went back to my doctor after that. I was like, okay, I just got out of the emergency room because they tested me for Alpha-gal.

I'm allergic to meat. So this is an allergy. Yeah. So all of a sudden you're looking at the quote crazies and they're not so quote crazy anymore.

Absolutely. We suddenly had a blood test. And of course, what turned out is all these patients who've been telling us this story were allergic to Alpha-gal. But it's still like a mystery.

Right. There are. Thomas Platt's mills couldn't figure out why people like Amy who had lived for 40 years in quarter house stakes at Peter Luger's with a credit card. Why would you suddenly develop an allergy now?

There would be some kind of trigger. Yeah. So we were looking for anything that could explain it. It could be a mold, it could be a nematode, a worm or a fungus.

But then he looked again and noticed that all the people who had bare reactions to the cancer drug were in a particular area of the country. Was Virginia, North Carolina, South and Missouri. In Arkansas. In Arkansas.

In suggLEc city no cases in Denver smatterings down the west. So he turned up his technician Jake and said, you've got a Google every map you can find and say what matches that area? Creatures or diseases that appear wherever the allergy appears. So Jake starts Googling and Googling and doogling and eventually he comes across a map that matches cases are very beautifully.

The maximum area for Rocky Mountain spotted fever. So he made this little map and it's like the shaded dark areas of the country are places of Rocky Mountain spotted fever and then there's like some stars where you know this allergy appeared. Yeah. And they overlap.

Oh, very interesting. And then all of a sudden it clicks. Rocky Mountain spotted fever is a tick-borne disease. This is the distribution of the lone snot tick.

And actually just a little before this, it turns out an allergist down in Australia, Cheryl Van Nuen. First name Cheryl is actually our whale, Van Nuen and Van Nuen and Van Nuen and I'm from the Tiki Newsalities Research in Wind and Center in Sydney, Australia. She says she was now being visited by all kinds of people who claim suddenly to be allergic to me. And whenever I take a history, so for example I'd ask them was there a family history of rhinitis, eczema, asthma, sinus, ectology and they say they all been bitten by ticks.

When we started asking patients, we suddenly heard the stories just out the kazoo. But at this point, Dr. Platt's Mill is off. He has is a map, some stories and a hunch.

Right. So what does he do? He decides, well, maybe I'll just do this myself. He decides to test it out himself.

Oh my god. He's sort of like denies that he did it intentionally. I know I had no intention. I think he also likes to walk in Amble and think about things.

Right. So he goes for a long walk along the Blue Ridge mountains. And I knew I wanted to be off trail because I'm actually rather allergic to humans. So he's walking and walking and walking along the way.

He bumps into a whole bunch of ticks. And if you've walked into a nest of those things, it sounds like a nightmare. Yeah, absolutely. I got 200 seed ticks.

Oh boy. And then in November, that year I was taking up to dinner and the lamb chops were particularly delicious and the French wine was delicious. And six hours later, I woke up covered in hives. He's got an allergy to read me all just because of a tick bite.

That's right. I'd like to write back after this. Hi, this is Sarah calling from Asheville, North Carolina. Radio Lab is supported in part by the Alfred P.

This is Radio Lab. Now we go back to Amy just when she's discovered that the allergy to me that she's developed comes from a tick bite. A tick bite? Hang on a second.

Because like a few weeks before all this started happening, as I said, I was forging for ramps in my mom's backyard and I had a tick on my arm. Now it turns out that not only was that tick bite a terrible thing for Amy, it was a kind of double tragedy. Hidden from a few amongst the trees and in the undergrowth. And I think it's only right at this point in back up.

It's a fascinating world of wonders and consider the story from the text point of view. Okay, so I'm Graham Hecling. I'm a wildlife disease call just at the University of Tennessee. So I was wondering if you could help us tell the story of, in case the loon start tick, that bit Amy?

Oh yeah sure. So they start off from this little pile of eggs, perhaps a mass of 2,000 eggs, under the leaves. The proud mom just gave birth to that one. She's just a kind of a withered husk.

I mean that. But anyway, a few weeks later those eggs will hatch and this mass of 2,000 may be text to merge from under the leaves. Could I see them with my naked eye? If you ran into a mass of them all up together, you would feel like you've got a little smudge of dirt and then the dirt starts walking.

And so they'll just climb up and they'll potentially all be on the same leaf for the same twig, looking for something to feed on. Now one teeny little tiny tiny tiny tiny tiny tiny tiny ticks is that they dry out. So when they come up from under the leaves, they come up briefly and then they go back out. Get a little water, come back up.

There's me, go back down and rehydrate. So they come mute. Exactly. And we refer to the haters questing.

So if you were one of these little baby ticks up questing for food while you're up there, you are essentially Velcro. Because when each one of your little eggs, you have little kind of hot like structures and so you're flat against the leaves sort of sniffing the air with your two little front legs. Like an attempt to see a true heat movement. So let's say Monday you're sitting there on your leaf and you pick up the simply nearby mouse.

Mice of the potato chips are the easiest. Maybe it's them. You might be about to have a very first meal. So you basically stand up, stretch out all your little legs and do a tick dance.

So it's kind of interpretive dance. Like movements. While you're waiting for that mouse to come just, don't know if you can grab on it. So you're dancing, you're waiting and you're dancing and you're waiting and you're waiting and you're waiting and you're dancing and you're waiting.

To be honest, you are probably going to wait your entire life and die unfulfilled. Because there are 2,000 of you starting off and a stable tick population. There's only going to be 2 of you that survive. Oh my gosh.

So 1,998 little baby ticks are born and then that's it for them. But let's say that you're one of the lucky ones and one sunny day. There you are. Hang on your leaf when you detect 2 incoming males.

One does a 4D roll. How many of them is her dog? Sorry. You heard that.

You press your legs out. Wave to the tick dance. And say you're waiting and you're dancing and you're hoping and you're hoping and you're hoping and you're hoping and you're hoping and you're hoping and you're hoping and you're hoping and you're slowly the dog can close your eyes. The reason that tick ended up on me was I slept in bed with my dog naked.

I mean she's always naked but I was okay. That's not gross. I don't. I mean, that's not weird.

No, but how do you know that's what happened? Because I know that I did a good tic-tac on myself, and I took a shower and everything, and then in the middle of the night I woke up with a itching sensation, and I went to the bathroom, and I couldn't really see what was on, something was on the back of my arm, and it was a tic. So as the tic is biting into Amy, what is it giving Amy that's going to be allergic to me? Well, I need to stop you there, Robert.

Tic-tac-tac-tac, I don't know the answer to that. That's Peter Sniff, and well, we're joining us this show then, and in the scientists, it's all up for circulation. We don't really know, but here's the theory. So normally we need a piece of meat, you put alpha-gal in your stomach, and your stomach tubs are just sitting in your body.

But the tic, can't even eat well, dro monthly, and jinx, it's saliva. We'll call that tic-spec, tic-spec, into its victims, straight into its victims, largest organs, the skin. And it has anti-clapping factor, anaesthetic, anti-inflammatory compounds, and we think the alpha-gal. Now, Peter says the thing about the skin is the skin is like this in the arm-Well, it's like surveillance system.

It's always on the lookout for invaders. So when the alpha-gal comes through, your skin cover by all that bad, bad, tic-spits stuff. That's going to really like set off your immune system. The immune system frees out.

Like, oh, uh-uh. And the Alpha Gal covered now in bad spit. Almost sort of by mistake. It gets label bad.

And now it's on the bad guy. Watch this. So, the next time you eat meat, the meat comes in. And then, the body unleashes wave upon wave upon wave of chemical tax to do battle against this Alpha Gal.

And this reaction gets way out of hand. You've got so many antibodies. Multiple, multiple, multiple, multiple, multiple, multiple, multiple, multiple, multiple. Making you rather than just aiming field.

Horrible. Right? I mean, it's very weird. It sounds like a science fiction movie.

It sounds like the beginning of a science fiction, at least kids book. Let's not go to movie. But like, it's just strange. Which all goes to say that this really is a kind of double tragedy for Amy and her tech.

Yeah. Because it takes them all to, like, humans. Right. We're on stake.

Like, we have opposable thumbs. We're either going to pull them off. I actually woke my mom up and she helped get it off. Or if they drop off, they're going to drop off in an apple terminal.

Or we'll not pop off. Or share carpet. Or share carpet. It was.

And I don't. And for us, well, we lose something. That historically, anyway, is a big part of who we are. Yeah.

Because we have, we adapted in the grand evolutionary schema things to, like, eat flesh. To eat meat. Yeah. Yeah.

I mean, I'm actually sitting here picturing a steak. But actually, the thing, I mean, hot dogs, like, wrap ramps around a weenie and roast. Yum. That's a good amount of water.

Weenie's ramps. Yeah. But I'm going my just tomorrow. Because I did, you know, I was reading about this algae a lot when I first got it.

And I read that for some people. The algae can fade away. So I'm going to get a blood test to see what my blood level of alpha gal is. So I'm a little.

So we'll be hoping for tomorrow. I want to be normal. Again. That was the end of the day.

And Amy conversation. She was going to go to the doctor, get her stuff tested. Find out whatever. So we asked her back in.

Okay. Find out what happened. So I actually did get an appointment with my allergist, Dr. Corn.

It was Dr. Corn. She's really nice. So I got the point.

I got the blood draw, whatever. And a few days later, my doctor called me and she said that my numbers were still really high. And I was like, well, how high are they? And she was like three.

And I was like three. And she was like, they're supposed to be like one or something. So they had gone down, but they were still, you know, many times more than they should be. But when you left and were waiting for the call, were you waiting with the hope that you would soon be eating a bit of hot dogs?

I mean, honestly, I was hoping. No. No. No.

I was afraid that she would be like, oh my God, your numbers are so low. You probably eat meat. Let's do a food challenge. I'll be like, ah, because like, that's such a scary memory.

Yeah, I don't, you know, actually just the other night I was eating at an Indian place and I was eating vegetarian. But like, I felt something and I pulled it out in the dim light of an Indian restaurant. Like why are they all that? Like I was like, was this big?

And I suddenly, you know, like you just get this drop in your stomach. And I'm like, what time is it? Four hours from now? Because there's something about it being delayed that makes it so difficult.

It just is like. Like it's a spins movie with you. It could happen in the next three hours or maybe not. I mean, honestly, the only thing that the real reason I want to be able to eat meat is so that I will be prepared to eat it in case of emergency.

I mean, I went on a canoe trip in the Adirondacks and I was like, what happens if I get stranded out here? I'm like, what if I have to hunt, but I can't even eat meat? I don't have to hunt fish, but then when the lake freezes over, what would I eat? I can't survive.

Something's wrong with me. I feel evolutionarily challenged. This is what I think about before I go to bed every night when I be able to survive. Just what's on me right now, a pen, underwear, my job.

And so, yeah, I mean, that's a real issue. It's like, it's not a real issue. I don't think I would go back to eating meat necessarily. Like, you are still more frightened than game, so to speak.

Well, also like, I wish I could be a vegetarian for ethical reasons because it's not so much just eating meat, but just like, you know, the factory farming, that kind of stuff. So, I feel like more at least superior now. I can be like, well, I don't eat red meat. Of course, I'm forced to not eat it, but at the same time, if I had the willpower, I'd probably go that way anyway.

And then also, I think it's great. It's like, we're all evolving to be on this planet, which is getting harder to be on. And we know that meat takes a lot of resources. And like, now I'm not doing that.

So, like, the ticket's helping me. So, like, we're all evolving. Like, so, one could, instead of thinking of the tick, as your teeny, reeny, irritating enemy, you could think of it as a guiding light, making the world safer to share with your fellow riffslings. Yeah.

So, you may have lost a relationship with meat, but at least you have your moral superiority. Yeah. I mean, I am superior. Yeah.

So, huge thanks to Amy Pearl for telling this story, which never stopped being scary and wonderful. And to the fellow who brought her into the room, Dan Hashwin, whose podcast, The Sportful, is it's all about food in every conceivable way. Like, he talks about eating it, preparing it, worrying about it, as you've heard getting sick from it, getting fat from it, getting fat from it, whatever. And you can find his show on iTunes, or Stitcher, or on the internet at sortful.com.

And this story was produced by Annie McEwen and Kilti, with her buddy, Amy! And Homie! If I get, like, cut off from group when I'm out on a tour of the woods or something, and I have to sleep overnight. a frog, a bug, but I couldn't eat like squirrel on the house.

I guess I could eat a bird. I mean, I don't know. Like, feel myself? No, but you could help me out with animals but not you.

I know, it's so like a chimp burger. Maybe, think even more darkly. A human, another human, baby? No, what you say, baby?

No, no, no. I'm not a piggy. Or a nori candle. I'm really going to go for it.

I'm going to go for it. I'm going to go for it. I'm going to go for it. But turkey meatballs are f***ing awesome.

But turkey meatballs are f***ing awesome. That's awesome.
