Defeating Huntington’s disease starts with taking care of yourself and joining Enroll-HD

For those of us affected by Huntington’s disease or at risk for it, the fight against the disorder begins by taking care of ourselves.

This idea occurred to me during my daily morning meditation on Jan. 14, 2016, as I anticipated my annual checkup in the Enroll-HD program later that day.

Many people struggling to come to terms with HD ask: with so much to worry about, how can I contribute to the cause?

You can start simply by committing to care for your health and asking family members and others to help monitor your condition. In doing so, you will help your family, too, by preparing for and perhaps even diminishing the current or eventual caregiving burden associated with Huntington’s.

You can extend that assistance to the entire HD community by joining Enroll-HD, a worldwide registry of affected individuals, asymptomatic HD gene carriers, untested at-risk individuals, and other family members. With its growing database, Enroll-HD serves as a platform and research project aimed at facilitating clinical trials and the discovery of treatments.

The greater the participation in Enroll-HD, the faster trials can take place.

Helping the researchers

Not long after learning of my own risk for HD in 1995, I started participating in research projects based at the University of California, San Diego (UCSD), and San Diego State University (SDSU) (click here to read about one example).

In January 2015, shortly after my participation in the PREDICT-HD study ended, I registered in Enroll-HD.

At this month’s follow-up visit at the UCSD Huntington’s Disease Clinical Research Center, I once again gave blood that scientists can use in the numerous research projects facilitated by Enroll-HD. I also underwent a battery of cognitive tests.

In addition, I participated in four research projects by scientists at UCSD, SDSU, and other local institutions. Two involved standing on high-tech platforms designed to detect  balance problems in people who have brain disorders and concussions. Another involved a measure of fine motor skills, which are seriously affected in HD, by writing on a special tablet connected to a computer.

Finally, I spit into a tiny collection tube for a project involving the detection and study of the huntingtin protein in saliva. Abnormal huntingtin causes HD.

A neurological exam

My visit concluded with a standard neurological exam by Jody Corey-Bloom, M.D., Ph.D., the director of the UCSD clinic. Among other tasks, I had to follow her fingers with my eyes, rapidly tap together my thumb with my index and middle fingers, and walk down a straight line for about 25 feet.

To my great relief, Dr. Corey-Bloom noted no irregularities! At 56, I am now past the point at which my HD-stricken mother displayed the characteristic involuntary movements.

Afterwards, I discussed with Dr. Corey-Bloom my questions and concerns about my potential participation in the SIGNAL clinical trial to test a monoclonal antibody as an HD treatment.

I will soon provide an update on SIGNAL.

Enroll-HD’s positive impact

The next day, I obtained the latest news about Enroll-HD from Joe Giuliano, the director of clinical operations for CHDI, the multi-million-dollar nonprofit virtual biotech aimed exclusively at developing HD treatments. In collaboration with HD research centers and clinics around the globe, CHDI sponsors Enroll-HD.

Enroll-HD officially launched in July 2012. According to Giuliano, as of January 15, nearly 9,000 individuals from 14 countries and 140 sites had signed up.

Has the program met CHDI’s expectations?

“I think there’s a high level of engagement among the patient community and among the investigators around the world,” he said during a phone interview. “The recruitment has been excellent. We could have 10,000 participants by the end of March, which would be amazing. I’m really pleased with how well the availability of the dataset and the biological samples [blood] has worked out. In other words, people are using the data, and the data is available through the website. It’s a great example of making data available quickly.”

What’s been the impact?

“We’ve been actively assisting three clinical trials that have been going on – PRIDE, Amaryllis, and LEGATO – with their recruitment,” Giuliano continued. “We have released our second periodic dataset, with 4,150 participants. There are 28 projects that are currently using Enroll-HD data, to answer different research questions. We’ve been actively distributing biological samples for a variety of projects.”

As a result of Enroll-HD, scientists are deepening their understanding of the disease, and doctors are finding ways to improve care.

Enroll-HD contributes directly to the quest for treatments. The larger the number of potential clinical trial volunteers, the greater the chance that trial administrators can enlist the required number for each trial. The number of HD trials has increased each year, increasing the demand for volunteers. Without the trials and the volunteers, scientists can’t test treatments.

Challenges in Latin America

On the downside, in one key region, Latin America, Enroll-HD has progressed “very slowly,” Giuliano said. So far, Enroll-HD is only operating in Argentina and Chile.

In October 2015, the National Research Ethics Commission in Brazil – the world’s sixth largest nation, with an estimated 20,000 HD-affected individuals – rejected the proposal to set up Enroll-HD there.

“Obviously we were very disappointed,” Giuliano said. “I think the National Research Ethics Commission rejected based on some areas where there was a perception that the Enroll-HD study was not aligned well with some of Brazil’s legal precedents.”

However, Giuliano said that Enroll-HD will step up efforts to involve Latin America’s HD families. With growing interest in Colombia, that country be the next to join Enroll-HD, he said.

“We’re working harder than ever,” Giuliano affirmed. “You haven’t heard the end of us in Brazil. We’re really committed to Latin America. Many of us believe that Latin America, like in the beginning of their history of HD research in Venezuela, which played an important role – now in the later stages of HD research it’s going to resurge, reawaken, and become an important player in HD research again.”

In a future article I will explore the Brazil decision in depth as well as ways HD families can push for greater acceptance of Enroll-HD there and in other countries of the region.

Building a common cause

As I approach the inevitable onset of HD and feel many of the other effects of normal aging, I realize more than ever the need to stay in shape via a healthy diet, daily stretching and aerobics, meditation and spirituality, and psychotherapy.

Without health, I cannot work, dedicate myself to my family, or advocate for the HD cause.

Caregivers, the "HD warriors" who enter the trenches each day, must also seek opportunities for respite.

With the significant progress towards HD treatments of recent years and growing awareness of the importance of HD and other neurological disorders, advocates have a busier agenda than ever.

I am thrilled to assist HD research and the implementation of the critical clinical trials by taking part in Enroll-HD.

After following the HD movement in Brazil for two decades and participating in the historic sixth World Congress on Huntington’s Disease there in September 2013, I aim to join my Brazilian HD brothers and sisters to advocate for reconsideration of the government’s rejection of Enroll-HD.

We must not lose the momentum in Brazil and Latin America!

Only by building this common cause can we ultimately defeat HD.

The end of fear and exclusion: informing my health insurance plan about the risk of Huntington’s disease

In my nearly two-decade journey with Huntington’s disease, I hid my at-risk status not just from nearly all but my closest confidantes, but also from my health plan.

My warily guarded secret exemplifies the deep-seated fears many in the HD community have about denial or loss of insurance coverage. I regularly read or hear about untested at-risk individuals or gene carriers who worry about this issue.

To protect myself from losing coverage in the event of a job change or another of life’s unforeseen challenges, I instead have relied all these years on the Huntington’s disease clinic at the University of California, San Diego (UCSD) hospital. There I have paid out of my own pocket for consultations and established a medical record completely separate from all my other health records.

As a university professor, I have enjoyed the benefits of group coverage, from which it is at least theoretically more difficult to exclude people who have genetic and/or pre-existing conditions. Nevertheless, I have always erred on the side of absolute security, never knowing what life might bring, especially in the period before I obtained tenure and therefore had some but not total job security.

Over the past two months, however, I have initiated the process of informing my health maintenance organization (HMO) that I carry the mutation for HD.

“This is all so ironic!” I said the other day to my wife Regina, the very first person I had told about HD after learning the day after Christmas 1995 of my mother’s diagnosis and my own risk for inheriting the mutation. “I’m now doing what I've avoided all these years.”

Fearing exclusion, I had not resorted to the very system supposedly designed to help me.

Feeling liberated – again

Once again – as I did in definitively exiting the terrible and lonely “HD closet” on November 4 of last year – I feel liberated.

I began to apprise my HMO of HD on August 9 with a visit to my primary care doctor, who has treated me for about six years and with whom I have developed a comfortable and cordial relationship.

I had made the appointment to address a benign skin problem and other minor issues. Finally, at the end of my list of concerns, I came to the most important item. I had rehearsed the scenario in my mind many times. I decided to go right to the point.

Almost matter-of-factly, yet with the feeling of a huge wall coming down from around me, I told him that my mother had died of Huntington’s disease and that I had tested positive.

The doctor maintained his usual professional calm. At first, I couldn’t tell whether HD represented for him just another item on my list or something really significant.

From the ensuing conversation, I was reassured to learn that he clearly knew about Huntington’s disease. He also knew the work of the UCSD HD clinic. In fact, he had previously worked several years in another sector at UCSD.

I handed the doctor a printout of my article “Racing Against the Genetic Clock,” published last November in The Chronicle of Higher Education. He promised to read it soon.

My article, written “to combat the stigma and fear surrounding Huntington’s and other neurological disorders” and “to help galvanize support for increased brain research,” revealed my HD status to the many readers of the Chronicle print edition and website and, significantly, to my professional colleagues in the fields of history and Latin American studies.

It also set the stage for informing my doctors about HD.

“I truly enjoyed reading (your) article during my lunch today and plan to keep it around when I have visitors in the office for them to review,” my doctor wrote in an e-mail later that day.

On a subsequent visit, he showed me the file where he kept my article and others about patients’ responses to challenging health conditions.

Visiting the neurologist

With a referral from my primary care physician, I then scheduled an appointment with one of the HMO’s neurologists in order to establish a relationship with a specialist in disorders such as HD and obtain a baseline reading of my neurological health.

A few days before the appointment, I faxed her a copy of “Racing Against the Genetic Clock” to provide her a detailed picture of my family’s history of HD.

At my October 7 consultation, the doctor thoroughly examined me for signs of classic HD symptoms such as difficulties with memory and the inability to walk along a straight line.

As in previous consultations at the UCSD clinic, the doctor saw no evidence of symptoms.

We discussed the various psychiatric medications that I take to help remain psychologically stable and at least one of which might protect brain cells, according to one of the physicians at the HD clinic.

I added that I would schedule an appointment with my HMO psychiatrist to help in my struggle to deal with both the psychological stress of living at risk and to do all that is medically possible to protect my brain from a disorder for which there is no proven effective treatment.

The neurologist and I also discussed the supplements I take, such as creatine and coenzyme Q-10. She immediately arranged for blood tests to check for any deleterious effects the supplements might have on my kidney and liver. To obtain this same information in the past, I had always gotten these routine tests by requesting a check on the effects of the psychiatric mediations, but without mentioning that I took supplements.

Unfortunately, my HMO will not pay for these supplements, which cost close to $2,000 per year. The health establishment does not recognize them as valid for attacking HD, as they’re in the experimental stage: several such substances have undergone study in mice and even humans.

(Similarly, for more than a decade I have consulted with a private psychotherapist who knows about my HD status but whose services are not covered by any health plan or insurance.)

At the end of the consultation, I welled up with emotion as I thanked the doctor and explained to her how meaningful it was for me to have spoken about HD to a neurologist within my health plan.

Like my primary care doctor, she maintained a professional demeanor. However, I was very happy that she agreed to receive e-mail updates of this blog.

Moving beyond the political and social drama

As I have so far felt vindicated in my decision to go fully public about HD and meld my professional and personal lives with my advocacy, so do I now feel extremely relieved and hopeful about integrating HD care into my overall health care.

By bringing these and other professionals into the HD loop, I am strengthening the team that I will need to manage the inevitable symptoms of the disease.

At the same time, I know that I stand on the edge of history with many other Americans who for the first time are testing the political and social waters in the wake of the passage of the Genetic Information Nondiscrimination Act, signed into law in 2009, as well as Obamacare.

In speaking to people from countries such as Canada and England, where public health systems allow (at least in theory) greater openness about genetic conditions, I recognize how long and difficult the path to medical transparency has been for me individually and for the nation as a whole.

It all seems like such a needless drama, which we have relived again with a U.S. government shutdown resulting from the political impasse over the implementation of Obamacare.

We in the HD community have truly suffered the brunt of exclusion, not only from proper health care, but also long-term nursing.

As I stated in my Chronicle article, “As knowledge increases about numerous other health risks, medical ethics must undergo profound revision, and a genetic-rights movement must arise. To borrow one scholar’s phrase, disease-gene carriers like me are ‘moral pioneers’ on the genetic frontier.”

During these past few weeks, I have felt very strongly that pioneering aspect of my life. I’m thrilled now to have my HMO joining me on this journey.

(Next time: Huntington’s disease and bioethics.) 

Lifting Huntington’s families’ spirits with the promise of clinical trials

Perhaps nothing lifts the spirits of struggling Huntington’s disease families more than news about research breakthroughs.

With people emitting oohs and ahs about some of the key developments, you could feel the excitement in the room Monday evening, September 24, as Jody Corey-Bloom, M.D., Ph.D., presented her annual research update to the support group of the San Diego Chapter of the Huntington’s Disease Society of America (HDSA).

The director of the HDSA Center of Excellence for Family Services and Research at the University of California, San Diego (UC San Diego), Dr. Corey-Bloom kicked off the update with the hottest topic in the HD research world: gene silencing techniques aimed at attacking the disease at its roots.

“This is a big thing,” Dr. Corey-Bloom stated. “There are actually two methods to accomplish this that are under way in research labs around the world…. We want to switch off the gene that is responsible for Huntington’s disease. A lot of people feel very good about these techniques.”

Before a room packed with some 50 support group participants, Dr. Corey-Bloom proceeded to outline the efforts to set up clinical trials to test RNA interference (click here to read more) and antisense oligonucleotides (ASO) (click here to read more) as ways to block the negative effects of the HD gene, which produces a harmful protein.

“If we can get rid of this harmful protein, there’s a good chance that we could slow down the disease or even prevent it,” Dr. Corey-Bloom explained.

A trial in 12 months?

“It’s likely that we’ll see both approaches being tried,” Dr. Corey-Bloom said, noting, that, given the current state of the science, it appears that the ASO approach will enter a trial first.

Dr. Donald Cleveland of UCSD and Isis Pharmaceuticals, Inc., of Carlsbad, CA are nearly “ready to go” with a clinical trial, perhaps as soon as within 12 months, she observed.

“The critical thing to say here is that we really are edging closer to human trials,” Dr. Corey-Bloom emphasized.

The trial site has not yet been determined.

Dr. Cleveland, UCSD’s Ludwig Institute, and Isis will be honored at HDSA-San Diego’s 12^th Annual Celebration of Hope Gala on November 16, 2012.

In the coming weeks, I will report in detail on the UC San Diego/Isis project, which is mainly underwritten by the CHDI Foundation, Inc., the multi-million-dollar, non-profit biomedical research foundation dedicated exclusively to accelerating Huntington’s drug discovery and development.

You can watch Dr. Corey-Bloom’s presentation in the video below.

The shock of HD’s reality

Having tested positive for HD in 1999 and watched my mother succumb to the disease in 2006, I was thrilled to hear the news about the Isis ASO trial.

I have tracked the progress of the project since early 2008, shortly after the start of the CHDI-Isis collaboration (click here to read more).

Isis had first estimated that a clinical trial could start in late 2010. As with many scientific endeavors, delays have occurred. Now that a trial could realistically begin next year, I can once again fantasize about living free of this scourge that robbed my beloved mother of her ability to walk, talk, eat, and care for herself, leaving her a mere shadow of herself.

The support group meeting proved especially poignant for me because I had not attended for a number of months. After a summer break from my usual intense focus on HD, I once again confronted the reality of my own future in the faces of the HD-affected individuals I saw at the meeting.

Seeing these disabled individuals shocked me into renewing the fight to save them – and myself.

At 52, I am now at mother’s age of onset. Once again, I felt extremely lucky to have avoided the noticeable, classic symptoms of HD.

Imagining a healthy future

I have attended Dr. Corey-Bloom’s updates for about ten years. Each time, she manages to provide clearer and more comprehensive information.

Squeezing literally dozens of research developments into an hour-long talk and making it understandable for a general audience is no small challenge. As I told her afterwards, “You just get better every year!”

This year’s update especially served like a salve to calm my worries, which had heightened considerably after hugging one HD-affected friend who seemed to have declined since I last saw her a few months ago.

As Dr. Corey-Bloom spoke, I imagined this HD sister becoming healthy again and happily growing old with her family.
