Medical Research and the Gaps Between Cause, Treatment, and Cure

I am sick, and I am tired.
I am sick of being an anomaly.
I am tired of fighting against my body.
I am sick of reading headlines about unnecessary, yet well-funded, research.
I am tired of not being considered a sound research investment.
I am sick of competing for attention.
I am tired of being sent home without an answer.
I am sick of doctors who think they know more about a disease than the patients who live with it.
I am tired of doctors who know nothing about my disease at all.
I am sick of money being wasted collecting data that is too vague to provide answers.
I am tired of feeling as though any true breakthroughs will have to come from the patient community.

Every day fibromuscular dysplasia patients connect with one another in a Facebook group facilitated by the international, nonprofit organization FMD Chat, of which I am founder. Every day this group of patients checks in on one another. Every day group members discuss how they're feeling—physically and emotionally. Every day we share test results.

Every day we wonder why no doctor seems more interested in the similarities that are found in our stories. Every day we hope that rather than doctors calculating the percent of patients reporting certain vascular events or peering at biopsies and DNA samples that a doctor will ask us how we feel. Every day we hope for a treatment—much less a cure. Every day we are disappointed.

It grows more difficult not to become bitter.

Fibromuscular dysplasia (FMD) is a noninflammatory, nonatherosclerotic arterial disease that is most commonly seen in women. It may present at any age, but is more commonly discovered when the patient is between the ages of 20 and 60 years old. Just nearly a year ago, on January 30, 2012, I wrote about a FMD patient registry—which so far has cost more than $180,000—and at the time had yet to reveal any information that was necessarily "news" to the medical or patient community—at least those who were familiar with the disease. Of the first 339 patients enrolled, patients reported high blood pressure (66 percent); headaches (53 percent); rhythmic ringing in ears (30 percent); dizziness (28 percent); a whooshing sound in the ear (24 percent); neck pain (22 percent), according to data released at the International Symposium on Endovascular Therapy

Per Dr. Jeffrey Olin's presentation at ISET, "there has been virtually no new information in the last 30 years" regarding FMD, as the result of "small case series, case reports (the majority of published papers are single case reports), nothing on pathogenesis, little on genetics, nothing on imaging, little on methods of angioplasty, no new classification since Mayo Clinic 40 years ago." In saying as much, Olin does a bit of a disservice to his own prior publications on FMD and publications by those doctors oft associated with FMD. However, the 2012 conclusions drawn from the registry were widely familiar—FMD is often found by accident after a stroke or transient ischemic attack; it should be looked for in young patients with high blood pressure or migraine-type headaches; it can be diagnosed with angiography, CTA, or MRA; angioplasty can be used to open up affected arteries if done early enough; lood thinners and antiplatelet drugs may be prescribed; FMD can lead to a tear in the artery or permanent kidney damage; it is unclear what causes FMD; FMD is an underdiagnosed disease.

For patients to enroll in the registry they must travel to one of a handful of participating centers. Of the 339 patients included in the ISET report 148 were enrolled at the Cleveland Clinic in Ohio; 68 at Mount Sinai in New York; 35 at the University of Michigan; 32 at Alliance Health in South Carolina; 20 at North Central Heart in South Dakota; 18 at Ochsner in Louisiana; 18 at the Mayo Clinic. Data indicates that 328 procedures were performed on 171 of the patients enrolled, with 54.3 percent receiving Percutaneous Transluminal Angioplasty; 21.3 percent receiving Percutaneous Transluminal Angioplasty and Stenting; 8.8 percent receiving a vascular bypass; 4.9 percent receiving endovascular repair of an aneurysm; 2.7 percent receiving open surgical aneurysm repair; and 7.9 percent in the "other" category for therapeutic procedures. Of these 171 patients, 73.2 percent's target vessel was the renal artery. 

Such findings are of clinical value for those unfamiliar with FMD, and the conclusion that FMD presents in the carotid and/or vertebral arteries as often as the renal is indeed intriguing and aligns with the conclusion that "the most common presenting symptom/sign was hypertension followed by headache, pulsatile tinnitus, and dizziness." Patients among the FMD Chat community are well-acquainted with these symptoms; however, there remains a significant gap between recognizing the prevalence of these symptoms and treating them. 

Hypertension in FMD is caused by renal artery stenosis, which causes the kidney to emit renin, a chemical that raises the blood pressure. This hypertension often is treated with anti-hypertensives widely used in the general population. The problem is that FMD related hypertension often is resistent, requiring multiple medications and high doses to manage. These drugs—as with all drugs—come with their own sets of complications, and to many patients fulfill the cliche "the cure is worse than the disease" in terms of physical effects, as patients typically do not feel hypertension, known as the silent killer, while anti-hypertensive side effects such as swelling, coughing, chest pain, irregular heart beat, fainting, nausea, and shortness of breath are much more noticeable. Headache related to FMD becomes complicated by the fact that patients generally are advised not to take NSAIDs, which can cause kidney and stomach damage. Those with migraines are further restricted if prior vascular events such as uncontrolled high blood pressure or stroke contraindicate vasoconstrictors such as the commonly prescribed Imitrex. The Federal Drug Administration has approved no drug to treat tinnitus, and, based on what patients have reported within the FMD Chat community, dizziness typically appears only intermittently, making it a somewhat vague symptom to treat in any manner other than a directive to "stand up slowly." 

Granted, only about 250 of the approximately 7,000 rare diseases in the world have FDA approved treatments; however, treating symptoms of a disease is a different exercise than treating the disease's underlying cause. The FMD community is in dire need of measures to improve patients' quality of life. Research into the disease's genetic factors, while needed, does nothing to help patients currently living with the disease. And so a year after first issuing my plea, I say once again, "More must be done across the related specialities to address the issues that many FMD patients struggle with on a day-to-day basis including crippling fatigue and pain, the inability to work and lost income, depression and anxiety, isolation and fear. These issues are imminent threats to patients' overall health, and without a concerted effort to holistically treat patients there may well be fewer patients willing and able to participate in research studies."

What has changed in this year's time is that FMD Chat, then a fledgling organization, has grown, and that I am making it a personal mission to improve current patients' quality of life. Part of this mission is selfish—I am an FMD patient, and I want better care for myself. However, I also want better care for the hundreds of FMD patients who have made FMD Chat part of their support network and for all the patients FMD Chat has yet to reach. This mission is about making a difference and caring tenaciously for a group of patients in need, a group of patients that I have come to consider my friends and family.

Access Medicine X: Live Stream Brings Silicon Valley Direct To You

Stanford Medicine X is a catalyst for new ideas, designed to explore social media and information
technology’s power to advance medical practices, improve health, and empower patients to participate in their own care. But Medicine X also seeks to engage and empower those unable to attend in person to still get involved in the discussion.

Through Medicine X’s Global Access program, main stage content from the three-day conference will be made available through a high-quality live stream. Anyone with an Internet connection around the world will be able to view keynote speakers such as Daniel Siegel, MD, clinical professor of psychiatry at University of California-Los Angeles and author of The New York Times bestseller Brainstorm: The Power and Purpose of the Teenage Brain, and panel discussions such as Gonzalo Bacigalupe's focusing on the e-health movement and inequality among marginalized populations.

Crowdfunding Creativity

For as involved as I am in the national (and, at times, international) healthcare social media community, I find myself in a local void. The mountains I call home are not the epicenter of anything to do with healthcare or social media much less the two together. I've been chipping away, trying to carve out a foothold such that the wealth of education and opportunity found in healthcare and social media can enrich the lives of those I routinely connect with in real life as it has my own. It's slow going. Every fear, every socio-economic force that pushes back against the #hcsm tide can be found here. But today... today made a new friend.

As like minds are prone to do, @SociallyMD and I connected first via Twitter. Lo and behold — we live a mere 20 minutes apart. Prior to departing for Stanford's Medicine X conference, I suggested that since we were the only two Tweeps occupying the local #hcsm space, @SociallyMD and I should meet. And meet we did, instantly connecting profe…

Staircase Wit Leaves Us All Cold

Snow had fallen through the night, blanketing the mountains with an inch or more of glistening white. It was the kind of day best spent at home, but an appointment required that I drive to town.

I stopped at a gas station along the way. The station is near the corner of where my parents almost bought a house and not too far from where they actually did. It's open most hours of the night, perhaps even all 24 of the day, and is thus one of my regular stops.

A young man wearing an oversized black jacket and black knit hat pulled tight over his heat was standing directly inside the store's double doors, talking on his cell phone, as a middle-aged, female attendant mopped up melted snow from entryway. I grabbed some Reese's Cups and went to the counter to pay.

The attendant put her mop and bucket away, came to the register, opened the drawer, and began to count her cash. There wasn't much there—a twenty or two and a dozen one dollar bills for which she ran a receipt that she…
