“Oh, Dr. Siegel,” she said, her voice rising on the end of his name. He turned around swiftly without smiling, evidently in a hurry. “What’s going on with Susannah? Anything new?”
He stared back without his familiar warmth and optimism. “I’m not on the case anymore,” he said flatly and turned to leave.
“What, what?” she stammered, her lower lip quivering. “What do we do?”
“I don’t know what to say. It’s no longer my case,” he replied. He turned and walked briskly away. She suddenly felt very alone. There had been many low points throughout my illness, but this rebuff was the lowest. This doctor, one of the best in the country, had now, it seemed, given up on me.
She took another deep breath, straightened out her blazer, and headed back into my room. She felt foolish for believing that I had been anything but a patient—one in a series of numbers—to him. She could hardly stand to look at Dr. Russo when she came in later that afternoon. Now she was our only hope—that is, until Dr. Russo, as she was finishing up the examination, turned to my mother and said, “Dr. Najjar and I feel that a second spinal tap is now necessary.”
My deteriorating condition made the idea of another spinal tap, once so frightening, now seem insignificant. But my mother clung to the mention of a new doctor. “Who is Dr. Najjar?”
“He’s working on your daughter’s case. He’s a brilliant doctor,” Dr. Russo said.
Dr. Souhel Najjar had joined my team after a call from Dr. Siegel. His skill in solving a few mystery cases had earned him a reputation as the man to go to when nothing made sense. And now Dr. Bugsy was offering up his most perplexing case to him.
“I’m at a loss,” Dr. Siegel confided to Dr. Najjar. “I need your help on this case.” He listed all the issues and conflicting diagnoses. The psychiatrists suspected that my behavior stemmed from a mental illness; the elevated white blood cell count pointed to infection; all the other tests were coming back negative. Dr. Najjar’s first guess was that I had to be suffering from some sort of viral encephalitis, an inflammation most likely caused by the herpes virus. He didn’t buy the schizoaffective theory and instead suggested that they administer an infusion of IV acyclovir, an antiviral drug.
But then the virus panel came back negative. I did not have HIV or herpes simplex virus 1 or 2 and did not test positive for herpes encephalitis, so he stopped the antiviral infusions. The other possibility was that it was some sort of autoimmune response, which he could treat with an experimental immunotherapy that he had tried successfully on another patient with brain inflammation; the treatment included steroids, intravenous immunoglobulin (IVIG), and plasma exchange.
“I think we should do IVIG treatment immediately,” Dr. Najjar said after looking over my negative virus panel.
CHAPTER 24
IVIG
On April 2, the nurses started my first round of five intravenous immunoglobulin (IVIG) infusions. The clear IV bags hung on a metal pole above my head, their liquid trickling down into my vein. Each of those ordinary-looking bags contained the healthy antibodies of over a thousand blood donors and cost upwards of $20,000 per infusion. One thousand tourniquets, one thousand nurses, one thousand veins, one thousand blood- sugar regulating cookies, all just to help one patient.
IVIG is made up of serum antibodies called immunoglobulin G, or IgG, which are the most common type of antibody found in the human body.27 IVIG is approved by the U.S. Food and Drug Administration to treat problems relating to transplants, leukemia, and pediatric HIV, among other conditions; its off-label uses have often been considered “experimental” and denied by insurance companies.
Antibodies are created by the body’s immune system to counteract an unwanted, external element, such as when a pathogen of some sort—a virus, bacterium, fungus, or other foreign substance—enters the body.28 This sets off a series of reactions beginning with the body’s basic alarm system, the innate response, which is a one-size-fits-all process designed to get rid of unwanted visitors quickly. If the innate system can’t eradicate the pathogen, the next defense stage is the “adaptive response,” which tailors itself to the specific intruder, using an arsenal of white blood cells and antibodies. This takes much longer to mobilize than the innate response, ten days versus the innate system’s minutes or hours.29 Usually the collateral damage of these internal battles results in familiar flulike symptoms such as headache, fever, muscle ache, nausea, and enlarged lymph nodes.30
One type of white blood cell, the B-cell, also can morph into plasma cells that create antibodies.31 Under normal conditions, each antibody fits exactly to only one pathogen, like Cinderella’s glass slipper, with the purpose of blocking the spread of infection by either disabling that specific kind of pathogen or flagging it for destruction. But autoantibodies, which everyone has in healthy doses, can sometimes transform into the most malicious type of biological shadowboxer, if they begin to attach to and destroy the healthy host tissue, like the brain. An IVIG infusion introduces fresh, healthy antibodies to fuse with those “bad” rogue autoantibodies created by a sick person’s immune system, helping to neutralize them and rendering the autoantibodies harmless.
The next morning, my mother took her usual place beside me in a chair by the window when her phone rang. It was James. My parents had been keeping him uninformed about the severity of my illness, not wanting to worry him and disrupt his studies. He and I had always been close, despite the five-year age difference, and our parents knew he would drop everything and come home if he discovered how bad off I was. But today, for the first time, she decided to hand off the phone to me.
“James… James… James,” I said, hearing my brother’s voice on the other line. “James… James… James.”
In his dorm room in Pittsburgh, James choked back tears. I sounded so different, so unlike his big sister. He insisted, “I’m going to come home soon. And you’re going to get better.”
The following day, while I was on my second course of IVIG treatment, Dr. Arslan, the psychopharmacologist, came by on rounds and noticed that my speech problems had worsened. He wrote the following in his progress note:
It was the first time that anyone had mentioned the term
