Chapter 16: The story Dr. Gilden wrote
Chapter 13. Uh, violin. Uh, no. A Viola. Or. Mm. I mean, I dunno. A, a violin. Yeah i think it was a violin. Chapter 13. A violin is heard in Denver.
I literally read hundreds of articles. All while trying to keep our little family going with a newborn and two little kids and work and trying to help Danielle. And then one night, I was reading an article and something caught my eye. A name. I saw it in one of the references. Doctor Don Gilden. I knew that name from somewhere. I went and I read the reference. It's suggested that CNS vasculitis is often caused by varicella zoster, the virus that causes chicken pox and shingles.
But Danielle hadn't had shingles.
She had had chickenpox when she was a kid, but she wasn't elderly and she wasn't immunocompromised, and in any case, her spinal fluid had been tested for a number of viruses, including the varicella zoster virus, by PCR, nonetheless.
But as I was poo-pooing the idea, I heard a violin
13 years earlier, in the year 2000, while I was interviewing for neurology residencies, I had gone to Denver. Now the main thing I remember about Denver was the Tattered Cover bookstore on the 16th street mall. But that night, while I was sitting there, desperately reading review articles on CNS vasculitis. I remembered something else about Denver. I remembered Dr. Gilden's violin. You see, most interviews for residency, say with the chairperson of the neurology department, they were very business-like and formal affairs. But when I went to Denver to interview at the University of Colorado for neurology residency, in 2000, Dr. Donald Gilden was not formal at all and he was not businesslike at all. He had a violin in his office and a music stand and he told me about the origin of the violin which I was too nervous to remember.
He told me about great skiing around Denver. As I researched, reminiscing about Dr. Gilden and his violin, Danielle called down to me half asleep. I guess she could hear me typing. She told me something like, you're going to burn yourself out. You need to take care of yourself. Do you need to go to bed? You have to take care of the kids in the morning. I told her I'd be up to bed soon. Later, lying there next to her. I couldn't sleep. Dr. Gilden and his violin kept swimming around in my head. Even though I knew I was grasping at straws. Even though the idea of the varicella zoster virus causing this seemed totally out there, something in what he had written got me out of bed and I went downstairs and I wrote this email.
Dear Dr. Gilden. You won't remember me. But you interviewed me for neurology residency in 2000. I remember thinking what a nice man you were. And I think I recall you had a stringed instrument in the office. A violin, was it? Sadly, my wife has fallen ill and I'm hoping you might be able to give me some advice. She appears to have CNS vasculitis, similar to some patients described in your papers. Her spinal fluid PCR testing for HSV 1, HSV 2 and VZV were all negative about five to seven weeks after the onset of her symptoms. As described in your papers. I'm thinking we might need to do antibody testing for VZV on the spinal fluid sample. As you can imagine, this is a very scary and difficult time, and I'm doing my best to try and help her. Sincerely.
Roy Baskind.
I have sometimes had the problem of not being able to diagnose the difference between a violin and a Viola.
And I didn't want to insult him by calling his instrument by its incorrect name, but I wanted Dr. Gilden to know that he had met me. That I had been in his office. That we had some tenuous connection that I was trying to rely on now.
I sent that email. At 12:16 AM on January 8th. 2014. And when I wrote it, I was kind of thinking about it as a real shot in the dark, a real hail Mary. We had already tested Danielle's spinal fluid with the most sensitive test we have, which is PCR, and it was all negative for any infectious cause of vasculitis. So honestly, I didn't really think much about the email. Just a sort of desperate husband grasping at straws kind of thing.
I also had no idea if Dr. Gilden would respond to me. I had met him 13 years earlier for maybe, uh, 20 minutes. But when I woke up the next morning, Dr. Gilden had already responded.
Dear Roy. I am so sorry to hear about your wife's illness. Since she has a CSF pleocytosis and infarction, vasculopathy is indeed a consideration. I would be pleased to check her CSF and serum for antibody to VZV. Please send me at least 500 microliters of CSF and one to two milliliters of serum overnight mail at room temperature to me at the address.
Don Gilden MD Louis Baum endowed chair, and professor department of neurology, mail stop B182 University of Colorado School of Medicine, Aurora, Colorado.
What you hear in that email is not politeness. Don was truly sorry about my wife's illness. And if you knew Don, you know he was genuine about that.
The problem was this. We didn't have any spinal fluid to send to him. Not even 500 microliters. It was all gone. Used up. You'll remember that Danielle's balloon had been popped and it was leaking when she had had the lumbar puncture. She had been on two blood thinners. And so the tiny little hole that the needle made. And the canvas-like dura around her nervous system. That hole wasn't healing. And so the spinal fluid was slowly leaking out of the nervous systems compartment. So she had low spinal fluid pressure and because of that she couldn't stand up. Every time she would, she would get a headache and neck pain and become nauseated. She was literally pinned to the bed.
I had to basically lie down. Otherwise, I would get a headache.
There was not going to be a second lumbar puncture. Not for a shot in the dark diagnosis, thought of by her husband grasping at straws because he remembered a violin. Especially not while she was on two blood thinners that we were too afraid to stop.
There was no way any of us were going to repuncture that leaky balloon. There had been no DNA of that virus on a super sensitive PCR test. And as everybody knows, especially now after the COVID pandemic. PCR is king. Antibody tests. Meh.
But Dr. Gilden, just his few kind words. And that memory of his violin. And his grandfatherly way, they were something to grab onto in the tsunami that was dragging us out to sea, and I grabbed it. I called the lab to see if there was any spinal fluid left and the lab tech put me on a long hold while she checked in the fridge.
When she came back on the line. She told me, sorry, we've used it all up. I sighed, defeated. As the phone. I was going down on the receiver. She said something and I put it back to my ear. All I heard was SickKids.
In Toronto, the hospital for sick children has grown into it's oddly straightforward nickname, SickKids. For a long time. It was where all the PCR testing for HSV and VZV in the city would be sent. The chicken pox virus in the spinal fluid is usually considered a pediatric problem. The technician was telling me that a tube of fluid had been sent to sick kids eight days earlier and I should check to see if there was any fluid left there. Odds of that, um, about zero, I thought. I called the extension she gave me. It was a freezing cold Wednesday in the midst of the ice storm. The lab technician was annoyed. Some doctor from another hospital asking if there's any spinal fluid left from a test from eight days ago.
She said, hang on, hold on. Let me check. And she never came back.
I emailed our hospital lab manager, Manwell. Geraldo.
Hi, Manuel. I hope you're doing well. I have a strange request. My wife is ill. I need some of her CSF, but I don't think we have any left in the hospital. Is there any way you can see if you can track any of it down from any send-out labs that might have been done. I would so appreciate it.
He responded.
The team's looking for any CSF leftover. The chances are low since the sample was sent more than five days ago, but we will keep checking. I hope your wife will get better. Let me know if I can be of further assistance.
And then 24 minutes later on Wednesday, January 8th. At 10:24 AM. He responded with this.
Good news. SickKids has 0.5 MLS. What test would you like to run? Call me.
He told me that the lab normally keeps spare spinal fluid for five days.
Seven days had passed since her lumbar puncture.
But since those seven days straddled the new years holiday. They didn't count. We were in luck.
Toronto had been stricken with the worst ice storm in decades and the only problem now was getting the fluid across the frozen city and onto a plane to Denver.
I sometimes think how hilarious it is that there were probably thousands of liters of gas used to get that half a milliliter of spinal fluid from the hospital for sick children to North York General Hospital to Pearson international airport and up in a plane over the Rocky mountains to Denver.
Chapter 14. Chemical weapons
The treatment for primary CNS vasculitis. Is the same treatment we use for all inflammatory diseases that are presumed to be auto-immune.
Prednisone. And then wait.
Wait to see if it works.
I was really upset about going on a high dose steroids. The month that I was on high dose steroids was terrible. It felt like I, I, it made me feel really loopy. I would look at myself in the mirror and feel really distorted I don't know if I look the same or if my face got puffy or not, but I just felt like everything was very distorted. And, um, going to be on this medication for a long time and we didn't even know if it was going to help and so there was a lot of anxiety and uncertainty.
I was feeling very depressed. I was feeling very, kind of traumatized
But as bad as prednisone might be, the alternative was going to be much worse. If it didn't work, meaning if things turned south if she had another Tia or another stroke. Then the next treatment would be cyclophosphamide. One of the big guns, as we say. Which is ironic because actually cyclophosphamide is a nitrogen mustard, derived from a chemical weapon, actually.
It's chemotherapy with the idea that we destroy your immune system so it can build back better.
Chapter 15. Danielle's arm. Floats away.
After six weeks of hell. Things seem to settle down. Things went quiet.
Danielle's post lumbar puncture bubble in her head dissolved. She had no more migraine auras or numb arms and legs or headaches. She had been on prednisone for about three weeks and so it seemed like the prednisone was working. We moved back into our house. Micah was almost three months old now.
And things seemed okay.
One night, I slumped down on the basement couch after putting the kids to bed.
Danielle sent down to update her friends and family in an email and I was calmed by the sound of her typing at her furious typing pace. She sort of had a, yeah, things will work themselves out kind of rhythm to her typing. She was on the computer behind me. And I was flipping through the channels.
What got my attention was that. That pause. I turned around almost reflexively. Her left hand was still on the keyboard. But she was holding up her right hand and staring at it. Like it was an alien. She was turning it back and forth, looking at both sides.
What's wrong? I asked.
How fast do you think you type, like how many words per minute?
I don't know.
Okay.
You think I was typing so fast that-?
I just remember in my mind, you're like furiously typing ch-ch-ch-ch and suddenly silence. And then I turn around and look at you and you're staring at your hand. I remember I don't know if that's a false memory or not, but I remember standing in front of you next to the glass wall in the basement. You telling me that your hands floating away and as I think we're discovering here, me being absolutely terrified she's having a stroke, you just telling me that you're going to go to bed, me following you up the stairs, thinking should I call 9 1 1 now is and waiting to what was going to happen. You getting into bed and me just standing there, if you're going to have a stroke or not like, and at what point should I call 9 1 1?
This time, her neurologist husband knew she was having a stroke. But by the time we got upstairs, she told me it was passing.
Just a TIA then. She told me it felt like her arm had floated away. And then come back to her. It was midnight. She was already on aspirin and Plavix and prednisone, so what the hell was an ER doctor going to do for her? Anyway, I thought. I decided we did not need to call 9 1 1 or go to the ER. Nope.
I did not seek medical attention.
Instead I went back down to the computer and I sought my father's attention. I Skyped him.
My dad is a surgeon. But he has an old school breadth of medical knowledge and decades of experience doctoring and a razor sharp mind.
While we were complacent thinking things were getting better. She had just had another TIA. Back to square one. Three weeks on prednisone, a waste.
My dad told me what I already knew. The game was up. We had no other choice. Chemical warfare. Cyclophosphamide.
This is how auto-immune diseases work. Long, slow war. You don't want to kill too many civilians. So you, you keep your big guns back until your little guns fail. Cyclophosphamide is the big gun. It was time to scorch the earth.
Chapter 16, the story Dr. Gilden wrote.
I texted our neurologist who, although he must have been very annoyed by me texting him at midnight, responded to me kindly. We made a plan for Danielle to come to his office the next day and start cyclophosphamide.
I imagined her losing her immune system. While we treated an invisible auto-immune army in her brains, blood vessels, at least with cancer, you can see it on a scan. You can watch it shrink or watch it grow.
You can see its innards under a microscope
Now, we were going to give her chemo. For what? A presumed, probable, likely, what else could it be kind of diagnosis?
As one does, when you Skype your parents generally. You check your email at the same time. At least I do. Come to think of it. I checked my email while I'm video conferencing with just about anyone these days. I said, hang, hang on, dad.
And there it was. An email from Dr. Don Gilden. January 23rd. 2014.
Hi, Roy Danielle serum and CSF, both contained antibody VZV and the serum to CSF ratio of anti VZV IgG was greatly reduced. Those are the typical findings in patients with VZV vasculopathy. Call me if you want to discuss.
I call Don Gilden.
He didn't remember meeting me 13 years earlier, but he did confirm it was a violin.
I recounted to Dr. Gilden what had happened to Danielle and the last three months. The headaches. The confusion. The strokes. The blood vessels. The inflammation in her spinal fluid. The post lumbar puncture headache. The prednisone. And then the TIA she had had just a few hours before going to bed the night before.
I told him that we were on our way to initiate treatment with cyclophosphamide that morning. He took a long considered pause. And then he told me no, do not do that. Cyclophosphamide will kill her. She has a shingles infection in the brain's blood vessels. She needs to come off prednisone aSAP.
I was incredulous. But she had never had shingles.
He walked me through the antibody test. And then he took me by the hand and he told me the story that he had been writing through his whole career.
First. In 1983, Dr. Gilden and colleagues. Published an article in nature. Proving that the visa VI virus. Hides latent in the central nervous system. Waiting for its opportunity to reactivate.
Second, shingles can and does occur without a rash. I had never heard of this. I've come to realize that most doctors have never heard of this. So doctors, are you listening? There's a long, but not well-known story in the medical literature that spells it out.
Zoster sine herpete or shingles without a rash has been suspected for decades, but in 1992, and again, in 1994, Dr. Gilden and his colleagues published papers, marshalling all the evidence proving that zoster sine herpete can and does occur, shingles can occur without a rash.
And then he told me something that blew my mind. The virus that causes chicken pox. And then goes into hiding and the nervous system. And can reactivate to cause shingles. Sometimes without it's rash. It has a, another nasty trick up its sleeve. Instead of creeping out to the skin, along the nerves it can go down another nerve branch. And settle in the walls of the brain's blood vessels and set them on fire causing, are you ready for this? CNS. Vasculitis.
But I was incredulous. The DNA of the VZV virus had been checked with a PCR test. And it wasn't in Danielle's spinal fluid.
Looking in the wrong place, he explained to me.
Point number four. Unlike other infections in the nervous system that you can see on the battlefield in the spinal fluid. This was an infection hiding inside the blood vessel wall, and so the virus itself, its DNA and its proteins, they weren't in the spinal fluid. The DNA PCR test was insensitive. The wrong test. And since you can't go and swab the inside of a blood vessel wall, you have to look for antibodies being made and the nervous system against the virus. You have to look for your immune system's response to the hidden terrorist.
I was stunned. We cancelled our appointment to go and start cyclophosphamide.
It all made sense to me, but I was skeptical.
Dr. Gilden was used to facing skepticism.
As I'm sure he had done a thousand times before, he patiently explained to me what happens when you misdiagnosed VZV vasculopathy for primary auto-immune CNS vasculitis.
In 1995. Dr. Gilden did something so quietly bold. It gives me the heebie-jeebies. He and his colleagues, as he politely put it, quote, "restudied the pathological material of a patient who had died and been presented in the new England journal of medicine, clinical pathological conference."
The patient was a 73 year old man who had died of fatal vasculitis of the central nervous system while on prednisone and cyclophosphamide.
Dr. Gilden, like the investigator who arrives long after the plane's gone down deemed an accident, he sorted through the wreckage and found his terrorist hiding. This time in the, are you ready for this? In the blood vessel walls and the brain. That's right. In 1995. Dr. Donald Gilden found VZV DNA and proteins in the inflamed and closed off blood vessels of the brain of a man who had died and been deemed by the new England journal of medicine to have died of an auto immune vasculitis.
Meanwhile, his immune system had been immobilized by first prednisone and then cyclophosphamide while the virus ate away at his brain's blood vessels.
I love the title of the journal article. Varicella zoster virus, a cause of waxing and waning, vasculitis: The new England journal of medicine. Case five-1995. Revisited.
Huh, revisited.
Chapter 17. There's a pump in my fanny pack, in my fanny pack, in my fanny pack. There's a pump in my fanny pack, my fanny pack, ah pum.
Now we had to turn the ship around. We had to wean the prednisone as quickly as possible and start Danielle on an antiviral treatment. 21 days of intravenous acyclovir.
Acyclovir works slowly by feeding the virus blank bullets as it tries to build new DNA.
Starting acyclovir, I had this IV drip in my arm. I had to carry around- was that for a whole month? I had to carry around a little pack with an IV bag in it.
I remember it cycled and the pump started going on every few hours. It was the sound of the pump worrying, like we're click work, click work.
I shudder to think of what would have happened if she had gone on to cyclophosphamide. It would have further weakened her immune system.
And she may have ended up like that patient in the new England journal of medicine.
Danielle was cured. But the cure was not sudden, and it was not miraculous. There was no victory celebration.
There were just no more headaches. No more auras.
And no more strokes.
I guess we still didn't know what the, what the long-term consequences of this whole experience were and, I remember it put a lot of stuff into perspective about day to day and the kids, and just thinking like nothing else matters, except that we're and healthy together.
What do you think the long-term consequences have been?
Well, this is multifactorial, but I feel like I never got back to my level of, not competency, but like ability to, multitask and be organized and get stuff done. And, um, but it could be because I'm not back at work, it could be because I've got three kids, it could be, cause of all these other
things what do you think about your mood? Has it changed your mood?
I think my mood has changed, but again because I'm just less patient. I get more overwhelmed. I lash out more. I probably used to do it before as well, but it wasn't as pronounced if I didn't have any kids. And then if I had one kid or, and then I had two like the amount of lashing out increases.
Proportionate to the children you have?
How do you think that whole experience, whether it was the disease or the experience with just being sick or whatever dynamics, whatever the whole thing, if we just, just call the whole experience, how do you think it changed you?
I feel like this whole experience has marked us. Um, it's not just a happy-go-lucky life where not everything goes right anymore. It's like, this is, this is life. There's bad experience too. And they are part of your story.
Chapter 18. A terrorist without a belt.
Yeah. Indeed. That is our story. But the thing is, it's much bigger than just our story.
I think the big story here is the story that Dr. Gilden wrote over his long career.
He saw something that others didn't and he showed with careful science something that even to this day, most physicians don't know that this virus can cause stroke.
I know I'm not the first doctor or the last who has missed a diagnosis of shingles without its rash.
And I know I'm not the first neurologist who has missed a diagnosis of varicella vasculopathy.
Well, almost missed it.
I bet you even the world's greatest neurologists have missed it.
The problem is that when there's a visible rash, the diagnosis is a cinch. But if there's no visible rash, the diagnosis is not a cinch. The word shingles comes from the Latin word for belts. Cingulus as in a cinch because the rash that comes with shingles reminded early physicians of a ceremonial warriors belts. A belt they borrowed from the Greeks who called the rash zoster.
A ceremonial belt that a Greek warrior would wear around his waist with little studs on it.
And the Norwegians have the best name for it. Not only telling you where the belt comes from but how much it hurts. Helvetesild: the belt from hell.
So the names of the disease, regardless of the language, they harken back to the rash that it can cause.
But it's not just a rash
It's a neurological terrorist that hides in the nervous system.
And like a terror cell it waits for the right opportunity to reactivate, and when it does, it can cause all kinds of terror in the nervous system.
And here's the point. That terrorist, it can come from you with or without its belt.
I found that very hard to believe that something as common as shingles can cause so many different issues in people. Um, that the ones that aren't visible, the ones that don't cause lesions on the skin are not known about. And I just found this unbelievable. So thinking about all the people in the world over time, you have had unexplained strokes they're not sure what's going on and like, wow, this is really something that neurologists need to know about.
Sadly. Dr. Gilden died in 2016. In 2009, he was interviewed by the Lancet neurology and they asked him: What had been the greatest achievement of his career?
He answered.
Our lab was the first to prove that VCV is latent in human ganglionic neurons. We also prove that VCV can cause zoster sine herpete, pain without a rash, as well as vasculopathy.
And when he was asked “What would be your advice to newly qualified doctors?” he said:
Never forget that it is a privilege to care for sick people and that your responsibility is to continue studying medicine as long as you practice.
