CHAPTER ONE
THE RED FLAG DISEASE
Between them, Jan Pankey and David Calhoun shared four decades of experience as physicians. Yet in the quiet dark
of one August night in 2003, all that experience seemed to count for nothing. Something was going terribly wrong inside Jan's body, and neither husband nor wife could make sense of what was hap¬pening, or why.
It was shortly after midnight on the first night of a long-anticipated vacation in Montana when Jan awoke to a burning ache that encircled her upper chest. It was all she could do to draw in a breath. If Jan hadn't known better she might have thought she'd been pummeled with an iron rod across both front and back while she slept. Fumbling in the pitch black of their Idaho hotel room, where they had stopped en route to their final destination, Jan switched on the bedside lamp and stood for a moment in the circle of reassuring yellow light. Her legs felt unsteady. She couldn't feel the carpet beneath the soles of her feet. It took a blink or two for her mind to register that she was about to faint.
A minute later Jan came around to find herself staring at the coarse hotel rug, struggling to take in a full breath—trying to piece together where she was and why her upper body was in so much pain. In that split second every nerve ending inside Jan Pankey's body stood on full alert, signaling that something ungodly was happening. She crawled to the bed to wake her hus-band.
David quickly shook off sleep along with his bewilderment as to why his wife of twenty-eight years suddenly was writhing un-controllably beside him—in a hotel room a thousand miles from home and an hour from the nearest metropolitan hospital. Together they struggled to diagnose. Jan and David were well versed in the medical school mantra "When you hear hoofbeats, think horses, not zebras," and so they stuck to Jan's prior, known medical his¬tory rather than coming up with exotic could-be's. Recently, Jan, who was forty-nine, had started taking birth-control pills to help even out hormonal fluctuations and irregular periods. But that seemed of little consequence here. She'd also been plagued by bouts of indigestion, which her doctor had chalked up to gastritis, a chronic inflammation of the stomach and intestinal tract, due to a fairly common condition known as gastroesophageal reflux dis¬ease, or GERD. In GERD, the stomach overproduces gastric acid and the esophagus spasms, causing excess acid to rise into the frag¬ile lining of the throat. It can be quite painful.
Jan and David concurred that Jan must be experiencing spasms in her esophagus due to her GI problems. David felt that Jan's asthma must be acting up, too; recent forest fires had plagued Montana's wooded areas and some neighborhoods, and the nox¬ious smoke clouds had grown closer and more visible as the couple had neared the Idaho-Montana border. Still, severe chest pain was not usually indicative of asthma. Could asthma coupled with esophageal spasms produce so much pain? That was their best edu¬cated guess at one o'clock in the morning in the middle of no¬where.
Jan and David had left home early the day before with the goal of cycling more than a hundred miles of Montana's Glacier National Park, an expedition they had spent the past year plan-ning. Jan had been feeling well enough—you'd certainly never know that she suffered from any health issues to look at her. Slim and vitally active in the middle of life, she had already biked more than 3,300 miles in the previous twelve months. She held down a demanding professional schedule, commuting by plane from rural New Mexico to downtown Oakland, California, every two weeks to work long hours as a pediatric and neonatal anesthesiologist at Oakland's Children's Hospital. She was also a regular team mem-ber on physician-run medical missions overseas, helping children in third-world countries obtain lifesaving operations they might never otherwise receive.
The first night after departing for their big Montana trip—fourteen hours in the car after they'd left behind the rural farming village where they lived near New Mexico's Rio Grande—the cou-ple had stopped at their Idaho motel just shy of the Montana bor¬der. Once settled in their room Jan and David had turned on the air-conditioning to help filter out the polluted soot from the smok¬ing Montana fires that had drifted in behind them and hoped for a good night's rest. It was a few hours later that Jan's chest pain sud¬denly and inexplicably set in.
Then, just as unexpectedly, a few hours before dawn, the wrenching pain began to lift. Jan could take in a deep breath again. She told David she was feeling some relief. David felt reassured by Jan's slowly returning calm. He would later realize that it was a veneer Jan had perfected all too well after decades of reassuring parents with critically ill infants and soothing children who were about to undergo surgery.
That morning they crossed the border into southern Montana, where ash from the fires hung so thick in the air that you couldn't see across the street. Neighborhoods were being evacuated. As they got out of their Legacy station wagon to stretch their legs and sur¬vey the situation, Jan was seized again by debilitating chest pain and shortness of breath. She dropped to a crouch, gasping for air, unable to stand up.
Half an hour later David was wheeling Jan into the local hospital in Missoula. The emergency-room doctor reassured them that Jan's X-rays looked fine, except for a small, barely distinguishable anom¬aly: a slight shading along the lungs above the left half of her diaphragm, deemed insignificant. The doctor surmised that Jan's discomfort—and she was now twisting in pain on the hospital gur¬ney—might be a kidney stone. Urinalysis ruled that out. Nor was Jan displaying signs of wheezing. The ER doctor, stumped, con¬cluded that Jan and David's initial hunch had to be right: Jan was suffering from severe spasms in her esophagus due to her gastro¬esophageal reflux disease. In addition to the spasms themselves, Jan was experiencing muscle strain caused by the spasms along her chest wall. Or so the doctor thought.
The ER physician ordered an intravenous drip to be inserted in Jan's right forearm and dosed her with Demerol for pain as well as a sedative to help her relax. Afterward, Jan was given Prilosec for her gastritis and reflux, and was released. She felt she could and should go on with the trip.
Jan explained her feelings to David. "We've paid the money," she told him. "And I don't want to waste an opportunity we've been looking forward to all year because of stomach problems." Beneath her words David heard Jan's characteristic determination not to be a "wimp."
By the time the bike tour began later that afternoon, Jan wasn't so game, and she stayed behind at the hotel. But when the riders headed out again the next morning, she was resolute: she would ride the "sag wagon"—for lagging bikers—up the mountain a thousand feet, then coast down on her bike so that she could see the stunning vistas of glacier and rock she had driven so far to view. She was a veteran biker; what in the world could happen to her as she coasted down a mountain road? She donned her bike jersey, choosing one that would turn out to be all too fitting. Her jersey material was dotted with small red blood cells and sported the logo of the whimsical company that had made it, the Republic of Anaerobia—literally meaning "the .state of insufficient oxygen." Beneath the logo were the words Veni Vidi Vomiti. A twist on Julius Caesar's "Veni, vidi, vici" ("I came, I saw, I conquered"), Veni, vidi, vomiti was a hardcore no-sissy bike-til-you-drop insiders' joke: "I came, I saw, I vomited."
Jan began her glide down the mountain only to find that smog drifting from the fires nearly obliterated the view of the icy gorges and glaciered valleys. But that would turn out to be the least of Jan's worries. She had coasted another half mile in her red jersey when the now familiar vise of pain returned with a vengeance, nearly jolting her from her seat. She found it hard to pull in a breath. The scenery grew blurry. Colors turned to shades of black and white. She was close to passing out.
David discovered Jan crouched by her hike alongside the nar¬row mountain pass. All they could think of was getting back to the Albuquerque, New Mexico, medical center near their home where David was on staff, as fast as he could drive them.
Meanwhile, neither of them had a clue that in their empty pink adobe house near the Rio Grande the phone was ringing over and over again as the Missoula hospital's radiologist—who had fi¬nally reviewed Jan's X-rays—tried in vain to locate the couple.
They were halfway home—still assuming the pain was due to a wicked combination of reflux and gastritis—when Jan noticed a new problem. A hot, angry red line was moving up the vein in her right arm from where her IV needle had been. As a physician she knew a blood clot on sight. She knew that if it progressed it could easily block the flow of oxygen to her heart or lungs, causing a heart attack or even a life-threatening heart infection known as endocarditis. Jan took a dose of the antibiotics that she and David always carried in their first aid kit when traveling, and they stopped at a pharmacy for a heating pad to wrap around her arm to help disperse the clot—both standard protocol. They passed a road sign pointing to a local hospital along the deserted highway. David looked at Jan questioningly.
She shook her head no. "I want to get home to medical care I know we can count on," she told him. With Jan's eyes locked on the crimson line to make sure it wasn't progressing, they headed home.
Eight hours later Jan Pankey lay prone on a gurney inside the Albuquerque Regional Medical Center ER in severe pain, breath¬ing through an oxygen mask while a technician performed a scan of her chest. Jan watched from across the X-ray room as the picture of her lungs began to register on the machine. She didn't have her glasses on, but even so she could see the clots as they appeared on the scan. The technician stared at the screen in stunned silence, then turned to Jan and said, "Honey, I don't think you're going anywhere tonight."
The X-ray was startling. It looked as if someone had taken inch-sized bites out of several areas of each lung. Blood clots, or pulmonary emboli, had proliferated out of nowhere. Large clots were blocking several large arteries. Three of the five lobes in Jan's lungs weren't getting any blood at all, while the other two had been damaged by smaller clots. Together, clots had cut off 50 percent of the oxygen flow to Jan's lungs. The state of anaerobia indeed. It was a wonder Jan was still alive.
The ER physician on call later explained to Jan and David that the area above Jan's diaphragm that had appeared tinted in that first Missoula X-ray had been, no doubt, the first lung tissue to be injured.
The red line on Jan's arm hadn't progressed, so clearly the clots weren't originating from there. Additional ultrasounds re-vealed, however, that Jan's entire right leg vein was blocked from ankle to groin with a huge clot known as a deep vein thrombosis, or DVT. It was from this larger clot that smaller ones were travel-ing up to block the major arteries of her lungs. From torso to toes, Jan's blood was clotting up like sludge and no one could explain why.
Without knowing exactly what was causing Jan's condition, the ER physicians put her on the blood thinner Coumadin with the understanding that she would need to stay on it for several months to avert further crises. She stayed six days in the hospital before being discharged. But the second day home it didn't seem to matter that she was taking the full recommended dose of anticoagulants. Jan bent over to pick up a leaf that had fallen from a neglected plant in their foyer and felt "a hard thunk" in her chest that nearly toppled her. She called 911 and David, who was fifteen minutes away at work. The twenty-minute ride alone to the hospital in the back of the ambulance was terrifying.
"Even though I was wearing an oxygen mask I was gasping for every breath," Jan recalls. When David met the ambulance crew
at the hospital, they confirmed what he already feared. Jan's situa-tion was deteriorating.
The hospital was so full that day that they turned a U-shaped, curtained area of the emergency room into a temporary critical care unit to treat Jan. Kwaku Osafo-Mensah, a young lung special¬ist from Ghana who'd come to Albuquerque five years earlier after medical training at UCLA and Stanford, was rushed in to consult on Jan's case. Drawing the beige hospital curtains closed around her makeshift room in the busy ER, Osafo-Mensah quickly ex¬plained to Jan and David that even though Jan had been on blood thinners, X-rays showed that she had lost two more areas of lung.
Her EKG had as many spikes and valleys as the Swiss Alps. Jan and David were terrified.
It was as if someone had punched a hidden self-destruct button inside Jan's lungs and there was no shutoff switch to be found. She knew that if they couldn't stop the clots from forming, she would lose all the pathways by which oxygen entered her bloodstream. What was unfolding inside her body was petrifying; it was as if she were being suffocated to death by her own blood cells.
Osafo-Mensah shook his head as he talked to his new patient, trying to nudge the pieces together. Jan's first embolisms had devel¬oped during a long, two-day car ride to Montana. And she was often sitting on airplanes commuting from New Mexico to Oak¬land. Perhaps both sedentary activities had led to exacerbated clot¬ting. On top of that, anesthesiology is a pretty sedentary job, he explained to Jan. Still, it didn't add up. Not for someone like Jan Pankey who biked 150 miles a week.
Regardless of the diagnosis, Osafo-Mensah knew what he had to do if he was going to save Jan's life, and he knew there wasn't much time. He decided to immediately place a filter in the vein at the top of Jan's leg, known as the inferior vena cava, which pumps blood up from the lower two-thirds of the body. The filter would Stop any clots before they traveled up to Jan's heart or lungs. That, along with an intravenous infusion of the blood thinner heparin, would prevent more clots from rising toward her lungs.
It worked. Jan went home again. But a disquieting mystery still lingered in the air. Why weren't blood thinners working for Jan as they did for other patients? Jan scheduled an appointment with her local internist and posed the question to her, only to be brushed off with the words, "Well now, that's chasing a real zebra." Jan never went to her again.
Still, the insertion of the blood filter had made some difference for Jan; she was no longer living in a state of full-out perpetual crisis. The clots blocking the pathway to her arteries had dispersed, allowing oxygen to flow into her lungs again—except for the small percent of lung tissue that had died. Nevertheless, she felt so wiped out that she couldn't walk down a hall without pausing to catch her breath. Stairs were out of the question. Twelve hours of sleep did nothing to relieve her weariness. Many days, it was all she could manage to get out of her bathrobe and make a cup of tea by noon.
Despite the residual severe fatigue, weakness, and shortness of breath, she managed to attend a medical conference six weeks later.
At the conference, as serendipity would have it, Jan met a dynamic young physician by the name of Alex Spyropoulos, whose passion
was deciphering unusual clotting disorders. As the medical director and founder of the Clinical Thrombosis Center at Lovelace Sandia Health Systems in Albuquerque, Spyropoulos was presenting his research on designing new ways to use blood-thinning drugs. He also happened to be the author of a case report in a medical journal on a newly emerging autoimmune disease that dangerously altered clotting factors.
Reeling from what she calls a kind of "mortal exhaustion," Jan approached Dr. Spyropoulos after his hour-long lecture and put forth the question, "How could an active woman like me have recurring clotting even on blood thinners? What's happening to me?"
Two weeks later, Jan sat on an examining table inside Alex Spyro-poulos's office, relaying to him a medical history that had stumped half a dozen physicians. In addition to all that she had been through physically, she told him, she'd also been experiencing some cogni-tive problems—a kind of recurring brain fuzziness and forgetful-ness that deeply concerned her. Hearing this, Spyropoulos looked up over his notes at Jan, one thick, black brow furrowed. It was his dedication to tough cases that had earned Alex the nickname of "Dr. Spy" among patients who were grateful for his detective-like zeal on their behalf. He had a hunch, he told Jan, that she was not yet on a high-enough dose of anticoagulants. Rather than worry her by playing out possibilities, he ordered extensive blood work and, for added insurance, wrote her a prescription on the spot, upping her dose of medication. "If you have what I think you have, the anticoagulants you're taking will not be sufficient to do the job," he told her, ripping the script off the pad and handing it to Jan.
One week later, Dr. Spyropoulos received Jan's blood work and found his earlier suspicions confirmed. He immediately called Jan's office at Oakland's Children's Hospital where she was work-ing late. It was well into the evening and most of the hospital office lights were out. Jan still remembers hearing her line ring and rush-ing in to pick it up.
"I think I know what you have, Jan," Dr. Spyropoulos told her, excitement accelerating his delivery. Spyropoulos had already treated a number of patients with mysterious clotting problems who'd also reported the onset of "brain fog" as a debilitating symp¬tom. When Jan's blood work hit his desk, so did Alex's eureka mo¬ment. Jan's blood showed the precise biomarkers for an autoimmune disease known as antiphospholipid antibody syndrome, or APS, an illness he'd seen too often of late in other thrombotic patients.
"I had no idea what he was talking about," Jan recalls. "I had never even heard of APS." She fumbled for pen and paper in her darkened office. The three other doctors who shared her workspace had already gone home, and the hospital was unusually quiet.
Spyropoulos explained to Jan that APS, also known as "sticky blood," or Hughes syndrome, was an autoimmune disease in which the body produces antibodies, or immune fighter cells, that mistak¬enly disable the very proteins in the blood that the body needs to prevent excessive clotting. Without these proteins, called phospho¬lipids, your blood begins to clot and has no mechanism by which to stop clotting.
As Dr. Spy talked, Jan began to put the pieces together. One of the functions of the immune system is to act like a rapid-response SWAT team, reacting to any invading microorganism, such as viruses or bacteria, by producing antibodies—fighter cells—which seek out and destroy those unhealthy and often life-threatening organisms.
But in a wide range of autoimmune diseases, the body's im-mune cells lose their ability to read the difference between your own healthy cells and the foreign bacteria or viruses—or other un¬recognizable microscopic organisms from the environment around you—that enter your body. They don't stop at merely disabling these invading foreign agents, they go on to destroy the body's own healthy tissue in deadly rounds of friendly fire. For reasons scien¬tists are only now beginning to understand, the immune system goes on an erratic rampage, disabling the body itself.
In Jan's case, antibodies that were supposed to keep her healthy were instead attacking the very phospholipids that were instrumental to keeping her blood from clumping like cottage cheese in her veins.
Antibodies that turn on one's own tissue are known as auto-antibodies—antibodies meaning "fighter cells," auto literally mean-ing "self." As with many of the more newly recognized autoimmune diseases, isolating and testing for specific autoantibodies that point to the diagnosis of APS can be tricky to perform, and new blood tests for APS, in particular, are hard to compare from one lab to the next. At Jan's office visit several weeks later, Dr. Spyropoulos ex¬plained to her that her screening test was "positive for autoantibodies that show you have APS." Although a second follow-up blood test didn't confirm as high a level of those autoantibodies, nevertheless, Spyropoulos told Jan, "I think it fits. Your body is certainly acting like you have APS." In 2003, antiphospholipid an-tibody syndrome was a recently discovered disease; physicians had only known of its existence for twenty years. "There may be other antibodies involved that we don't yet understand or know how to test for," he admitted to Jan. "But that doesn't mean that we can't name and treat your disease."
Dr. Spy started Jan on much higher than usual doses of the heavy-hitting anticoagulant Coumadin, which is often required for patients with sticky blood. He also set her up on a constant home blood-monitoring program so that she could keep tabs on her co¬agulation levels around the clock. When Jan failed even on this regimen, he started her on long-term self-injections of an antico-agulant known as low-molecular-weight heparin, which had only recently been used to treat patients with APS who had not re-sponded to Coumadin therapy.
Today, Jan has expert supervision of her case and is better able to manage her disease. But myriad threats still lurk in her future. Patients with APS have a dramatically increased risk of migraine, sudden stroke, multiple sclerosis (MS), and lupus, the latter a dis¬ease in which the immune system develops antibodies that can mis¬takenly attack a range of organs in the body, including the joints, kidneys, heart, lungs, brain, and skin. Like all autoimmune pa¬tients, Jan is statistically three times more likely than others to be struck with more autoimmune diseases down the road.
Meanwhile, four years after her diagnosis, the side effects from the drugs Jan takes pose additional problems. She lives with constant bruising that she describes as "permanent bands of discol¬oration across my abdomen." Recently, she knocked her foot against the side of a swimming pool, and what started as a tiny bruise morphed into a black and blue hematoma from heel to toe, requiring a trip to the ER.
Those kinds of crises are commonplace for her now. But Jan doesn't just worry about what might happen if she were to be insuf¬ficiently anticoagulated again. She worries, she says, "about uncer¬tainties like how long will I be able to stay in medicine?" Already, Jan has opted to retire early from the operating room, concerned that the damage APS has done to areas of her brain and her result¬ing brain fog might jeopardize her ability to keep "the promise I make to all my kids' parents that I will do my best to take care of them in the operating room." Having stepped out of anesthesiol¬ogy she has decided, instead, to work with children in palliative and hospice care.
She and David also want to backpack again, but she asks, "Will we be able to? What if I bleed and we're too far from help?" She also dreams of rejoining overseas medical missions to help chil¬dren. But she's not willing to risk falling sick far from U.S. borders. "U.S. doctors don't know much about autoimmune diseases in gen¬eral and APS in particular," she explains. "What about doctors in the remote parts of India or Belarus or Kenya or Brazil or the other places I have worked?"
Despite all this, she pushes herself to ride her bike, swim, and even run as often as she can. She pushes herself, she says, "because I'm afraid if I stop, I'll never get going again."
In a certain light, it makes sense that six out of the seven doctors whom Jan saw completely missed her disease. Healthy women in the prime of life rarely have lung clots, much less APS. Still, doctors didn't miss Jan's disease just because blood clots seem a counterin¬tuitive diagnostic call in a hard-core cyclist, or because APS is a relatively rare disease. Statistically, Jan's chances of having APS at the age of forty-nine were greater than her risk of having ovarian cancer or leukemia—uncommon cancers that physicians routinely test for when telling symptoms appear. In fact, recent studies reveal that antiphospholipid antibodies are found in 2 to 5 percent of the population. As many as a quarter of women with recurrent miscar¬riages end up being diagnosed with the autoimmune disease APS, and one in five women who've suffered blood clots in the legs or strokes in the prime of life test positive for APS, making it more prevalent in women than leukemia and ovarian cancer combined.
No, the real reason doctors missed Jan's syndrome is because APS falls into the category of one of nearly one hundred autoim¬mune diseases that doctors have only in the last decade begun to recognize and understand. Almost every one of Jan's physicians failed to see that she was suffering from an autoimmune condition because, like most day-to-day practitioners, they remain unin¬formed about how to recognize patients who are suffering from these diseases in the first place. Because Jan's disease was autoim¬mune in nature, they missed the call.
THE COLD, HARD NUMBERS
Most of us, at some juncture in our lives, have played out in our minds how devastating it would be to have our doctor hand down a cancer diagnosis or to warn us that we are at risk for a heart at¬tack or stroke. Magazine articles, television dramas, and news headlines all bring such images home. But consider an equally dev¬astating health crisis scenario, one that you rarely hear spoken about openly, one that receives almost no media attention. Imagine the slow, creeping escalation of seemingly amorphous symptoms: a tingling in the arms and fingers, the sudden appearance of a speck¬led rash across the face, the strange muscle weakness in the legs when climbing stairs, the fiery joints that emerge out of nowhere—any and all of which can signal the onset of a wide range of life-altering and often debilitating autoimmune diseases.
Imagine, if you can: the tingling foot and ankle that turns out to be the beginning of the slow paralysis of multiple sclerosis. Four hundred thousand patients. Excruciating joint pain and inflamma¬tion, skin rashes, and never-ending flu-like symptoms that lead to the diagnosis of lupus. One and a half million more. Relentless bouts of vertigo—the hallmark of Meniere's. Seven out of every one thousand Americans. Severe abdominal pain, bleeding rectal fissures, uncontrollable diarrhea, and chronic intestinal inflammation [...]
