MDA Conference to Explore Clinical Trial Design
Hiroshi Mitsumoto will chair MDA’s
ALS Clinical Trials conference in June. |
If New York Yankees baseball legend Lou Gehrig were
still alive, he’d celebrate his 100th birthday on June 19. But he died
in 1941, struck down by ALS when he was just 37 years old and at the
top of his game.
Today, as in Gehrig’s day, there’s still no cure for
ALS. Although many drug treatments have shown benefits in mice with
the disease, only one — riluzole — has passed muster in
human trials, and it staves off death by only a few months.
To try to bridge this gap and to mark Gehrig’s 100th
birthday, the Eleanor and Lou Gehrig MDA/ALS Center at Columbia University
in New York will host ALS Clinical Trials: The Challenge of the Next
Century, a scientific conference to be held June 13-15 in nearby Tarrytown.
The conference, fully sponsored by MDA, will bring together basic scientists
and neurologists who specialize in ALS, as well as officials from the
National Institute of Neurological Disorders and Stroke (NINDS).
Hiroshi Mitsumoto, director of the Gehrig center and
a member of MDA’s Medical Advisory Committee, will serve as conference
chair.
In the past, ALS researchers have considered several
possible explanations for the disparate results of mouse studies and
clinical trials.
They’ve raised concerns that the mice have a genetic
form of ALS, while humans probably have various forms of the disease
not suited to a "one treatment fits all" approach. Also, since
researchers know that the mice will develop ALS, they often begin treating
them before disease onset.
By contrast, people with ALS don’t receive a diagnosis
until they show muscle twitching and weakness, signs that the disease
has already begun to destroy muscle-controlling nerve cells.
Some researchers speculate that drugs effective in mice
might need to be combined in a "cocktail" to work in humans,
an idea that’s gained support from a recent study (see "Drug
Cocktail," February 2003).
Attendees of the Tarrytown conference will discuss ways
to improve clinical research on ALS, including changes in data collection
and analysis, identifying early markers of the disease, and testing
drug combinations rather than single drugs.

Cognitive Deficits in ALS Are Usually Subtle
by Margaret Wahl
Benjamin
Brooks says it’s important to distinguish
between cognitive changes brought about by respiratory abnormalities
and those attributable to direct effects of ALS on the brain. |
A number of reports in the medical literature, some
of which have found their way onto the Internet and into the general
press, have suggested that ALS does affect cognitive functioning
(thinking) after all. This comes despite more than a century of observation
that thinking is well preserved in this disease.
But these findings may have little meaning for people
with ALS at this point, says neurologist Hiroshi Mitsumoto, director
of the Eleanor and Lou Gehrig MDA/ALS Center at Columbia Presbyterian
Medical Center in New York.
"The disease we knew and the disease we know have
not changed," Mitsumoto says. "We simply have a greater research
armamentarium to detect subtle changes.
"In a strict sense, ALS
affects broad areas of the nervous system," he explains. "However,
clinically (with respect to experienced symptoms), it is [usually] a
pure motor neuron disease."
Mitsumoto says only about 5 percent of people with ALS
have significant cognitive difficulties. But when investigators employ
highly sophisticated techniques to investigate cognitive and other nervous
system functions, they "always find dysfunction in those systems."
And the cognitive deficits in ALS are generally subtle
— "not the usual memory deficit that we see in Alzheimer’s
disease," he adds.
Minor Changes
Maura Del Bene, an advanced practice nurse and clinical
administrator of the Gehrig MDA/ALS Center, agrees with the 5 percent
figure for serious thinking impairment in ALS. Most people with ALS
who have problems, she says, "have a minor processing change. It’s
not an overall memory or decision-making problem."
Following complex, multistep instructions can sometimes
pose a challenge, she says. Instructions may have to be broken down
into smaller bits.
Neurologist Benjamin Brooks, who directs the MDA/ALS
Center at the University of Wisconsin Hospital & Clinics in Madison,
says that low blood oxygen levels, especially during sleep, may contribute
to the apparent cognitive decline that sometimes occurs in ALS.
The
vast majority of people with ALS continue to think and communicate
well and often learn to use complex electronic devices if speech
muscles weaken. |
He says recent studies show that low blood oxygen levels
that occur during the night don’t necessarily show up with standard,
daytime respiratory testing. Research is needed to discern the difference
between cognitive changes due to the disease itself and the "physical
changes brought about by the process of ALS," he says.
Because of the recent reports, investigators at Columbia
will be among those examining cognitive involvement in ALS. The group
will use "a different approach, namely a more physiological, chemical
and biological analysis."
In the long run, such studies may lead to better treatment
or preventive strategies, Mitsumoto says. In the short run, they may
lead to a better appreciation of what families and patients are going
through and what, if anything, needs to be altered when professionals
and caregivers impart information to patients.

ALS
Online
Chat
With the Bishops
In December, the newsletter introduced you to MDA/ALS
Division co-chairpersons Steven and Jennifer Bishop of Arvada, Colo.
For the Bishops one of the most challenging aspects
of life with ALS (Steven received his diagnosis in March 2001) has been
dealing with the implications of the disease for their 4-year-old son,
Christopher.
That’s why the Bishops have begun a biweekly chat called PALS With Children. Every other Wednesday, from 12 p.m. to 1
p.m. (EST), you can join Steven ("alsretired") and Jennifer
("alswife") as they discuss the issues related to talking
with your children about living with ALS.
The first session of the Bishops’ chat was held Feb.
19. Sessions are scheduled on March 5, March 19, April 2 and April 16.
Time
Change for Caregivers Chat
The Caregivers Online weekly chat has been moved
to a new time to accommodate the schedules of participants in different
time zones. Host "shelia-s" invites caregivers to share everyday
successes, frustrations and tips each Tuesday from 7 p.m. to 9 p.m.
EST.

ALS Research Roundup
Center
Director to Be Part of Large ALS Respiratory Study
Neurologist and neurophysiologist Jeremy Shefner, who
directs the MDA/ALS Center at SUNY Upstate Medical University in Syracuse,
N.Y., is part of a large study of the respiratory effects of ALS —
the most deadly of ALS-related symptoms.
Much of the study will take place at Johns Hopkins Medical
Center in Baltimore, to which Shefner will travel at intervals. Hopkins
receives MDA funding for ALS research.
Loss of muscle power in the diaphragm
leads to serious respiratory impairment, which can be treated
with assisted ventilation.

|
Shefner was selected for the study because he’s among
investigators who have developed a technique called MUNE —
for "motor unit number estimation" — that counts the
number of muscle-controlling nerve cells and the muscle fibers to which
they send signals. Each nerve cell and its muscle fibers is one motor
unit.
Shefner will apply the MUNE technique as he follows
the loss of motor units in the respiratory diaphragms of mice and rats
with ALS.
"We’ll record how the diaphragm changes as the
animals get ill," Shefner says. "The point of this is to try
to identify a marker for respiratory dysfunction that we can use to
measure changes."
And the point of that, he says, is to have a way of
measuring whether treatments being tested on animals, and eventually,
humans, with ALS, negatively or positively influence the respiratory
course of the disease.
No human trials are planned for the immediate future,
but such trials are the ultimate goal of the research, Shefner says.
He notes that safety issues will be worked out in the rodents first.
Minocycline
Trial to Change Slightly
A study to test the effects in ALS of minocycline, an
antibiotic in the tetracycline family, will begin this summer at 16
centers across the country. Minocycline has shown promise in tests in
mice with ALS and in a small study of people with the disease.
Paul Gordon
|
Neurologist Paul Gordon, who currently directs the MDA/ALS
Center at the University of New Mexico Health Sciences Center in Albuquerque,
will become associate medical director of the Eleanor and Lou Gehrig
MDA/ALS Research Center at Columbia Presbyterian on April 1 and will
direct the minocycline study from there.
Neurologist John Chapin will replace Gordon as director
of the MDA/ALS Center in Albuquerque.
For information about participating in the minocycline
trial, contact Nayra Gad, project coordinator, at Columbia Presbyterian
at (212) 305-3985 or ng152@columbia.edu.
This is new contact information, replacing that in
the November 2002 issue of The MDA/ALS Newsletter.
Neuronal
Stem Cells Found in Blood
Researchers have discovered that human blood contains
cells capable of becoming nerve cells (neurons).
The finding is the latest advance in the search for
stem cells that might be used to replace or repair neurons lost to diseases
like ALS.
Recent studies have shown that adult bone marrow contains
stem cells capable of forming neurons and other cell types, raising
hopes that bone marrow transplantation could be used to treat ALS and
other diseases. But even the harvesting of bone marrow stem cells carries
concerns: The procedure involves administration of drugs that can cause
significant discomfort to the donor, including muscle pain and joint
pain.
In a new study, Eliezer Huberman and his team at Argonne
National Laboratory in Argonne, Ill., show that stem cells from circulating
blood can be induced to form several cell types, including skin cells
and neurons.
Blood could be used as an "easily accessible source"
of stem cells for transplantation, they write in the Feb. 26 online
edition of the Proceedings of the National Academy of Sciences.
Anti-HIV
Drugs Investigated for ALS
In late January, newspapers in Ontario reported that
a local woman with ALS saw her symptoms improve dramatically after 18
months on a drug cocktail used to combat HIV, the virus that causes
AIDS.
The woman, who is HIV-negative, began taking the cocktail
after her neurologist, John Turnbull, read two studies describing AIDS
patients who developed an ALS-like syndrome and then recovered from
it with similar treatment (see "HIV
Link," October 2001).
Turnbull, who directs an ALS clinic at McMaster University
Medical Center in Hamilton, Ontario, is now conducting a clinical trial
of the drug cocktail, formally known as HAART or highly active
antiretroviral therapy, in 15 people with the disease.
MDA has discussed working with Turnbull on future trials
of HAART for ALS.

WHY
RUN FOR ALS? IT’S PERSONAL
by Stu Green
It’s cold, it’s raining, it’s late, it’s exhausting,
it’s painful. And those are the plusses. And we haven’t even mentioned
dogs.
So, why do you do it? Why do you run? And why do you
make the calls, make the e-mails, make the letters and make your case
for MDA? Why all the work for a group most people probably only think
about once a year around Labor Day?
Why?
That’s not a question I can answer for you. Each person
supplies his own on this quiz. I can only offer my own answer.
Like many of you, I’ve thought about running the Boston
Marathon for a while. And, to be honest about it, getting an official
number was a huge incentive to join the Miracle Marathon Team. But it
went further than that.
For me, it hit home.
My Reasons
My brother, David, and his wife, Jean, raised their
two sons in Rochester, N.Y. It was an existence they loved — complete
with a suburban house with a vegetable garden, well-behaved children
and plenty of Little League games.
About four years ago, David, then 43, was playing tennis
with one of his sons. He was having trouble getting to the ball. He
knew something was wrong, and it was. ALS — a three-letter acronym
for tragedy and tears.

his brother, David, in 1993
|
The next three years were horrific for David as he slowly
lost his ability to walk, to move at all, to talk, to eat.
It wasn’t a hard decision for me to run Boston in 2001
and 2002. And it wasn’t a hard decision for me to go out and run in
the cold, the ice and everything that goes along with New England winters.
After a while, my brother was confined to a wheelchair.
Although it wasn’t the place he wanted to be, it was an amazing chair
that cost $30,000.
So, when I asked people to donate to MDA, I truly appreciated
the donation. They weren’t giving it to some nameless, faceless organization.
It was going to help a person. It was going to help my brother.
Many times, on many cold runs on silent, dark streets
next to a field or woods, I heard noises behind me. I turned around,
and no one was there. I knew, in that moment, they were echoes, echoes
of some very good people helping me to keep going, helping me to help
my brother.
It was a long battle, but my brother quietly slipped
away on July 31 of last year. He was 46.
Stu Green is managing editor
of the Norwood Bulletin in Norwood, Mass. He ran in the Boston
Marathon as a member of the CITGO/MDA Miracle Marathon Team
organized by MDA national sponsor CITGO. Green ran in the marathon
for two years, raising more than $8,500 for MDA’s ALS program.
This year’s 26.2-mile marathon
will be run on April 21, and the Miracle Marathon Team will
be there. Last year the team raised $247,000 for MDA. For information
about participating, visit www.citgo.com/Sports/Running.jsp or e-mail team captain Ray Belanger at Rbelanger@baycopy.com.

Your Own Reasons
So, what’s your answer to the question? You probably
don’t have one yet. If this is your first, second or 10th Boston, the
answer changes, and it changes us. It’s a running commentary, if you
will, on our lives.
So, this is my message for this year’s Miracle Marathon
team:
There are some amazing people among us. You don’t have
to look far.
To an onlooker, a pack of 15,000 can look like that
— a pack. But each person has a story to tell, a life to live. A race
to run.
The word "hero" has been bandied about so
that it’s a hollow image of your former self. Chuck Norris, Arnold,
Indiana Jones, the classic heroes? Perhaps. But, really, a hero is one
person who makes a difference in one other person’s life. Quietly. Consistently.
Always there.
You know who I mean, don’t you?
It’s not that they don’t stumble. They do. That’s not
the point. The point is, they get up again. And again. And again if
they have to.
They keep going. They get it done.
They’re there.
From my family, thank you all for being there. You do
make a difference.

Missouri Minister Delivers Opening
Prayer for U.S. House
by Tara
Wood
As leader of the Community Christian Church in Camdenton,
Mo., the Rev. Tracy Carroll is accustomed to heeding the call of a higher
power.
But in January, a call came from Washington, D.C., that
also garnered his attention.
On the phone was the office of the Chaplain of the U.S.
House of Representatives, inviting Carroll to give the opening prayer
in the House the following week.
It was a once-in-a-lifetime honor for Carroll, who received
a diagnosis of ALS in 2001, and serves as co-minister of the church
with his wife, Colleen.
Carroll, 44, was selected for the honor after church
members Billie Huddleston and Richard Derringer contacted their representative,
Ike Skelton, and told the Congressman about the Carrolls’ many contributions
to their community.
A Whirlwind Trip
One whirlwind week later, with Colleen’s help, Tracy
climbed steps to the podium and delivered a prayer. His words became
a recorded part of history as they were included in the day’s Congressional
Record, and were taped by C-SPAN.
"Grant assurance of the goodness of people across
this great land as we face various concerns in this generation. In gratitude
for institutions of democracy, grant courage to stand and to build consensus,"
Carroll prayed before the legislators.
The trip included more than the average amount of Washington
activity and security, as Carroll addressed the House on the morning
after the president delivered his State of the Union address.

Coughlin, chaplain of the U.S. House of Representatives; Rev.
Tracy Carroll; and Rev. Colleen Carroll.

In fact, the Carrolls arrived at their hotel two blocks
from the Capitol just a half hour before the president’s speech.
They were greeted by "helicopters, jets, police,
Secret Service, blockades and checkpoints…. How did they know we were
coming?" Tracy joked in his church newsletter.
Other highlights of the trip, for which the Carrolls
paid their own expenses, included lunch and conversations with Skelton
and other members of Congress, a unique look behind the scenes of Washington
and impeccable hospitality along the way. (And, yes, Carroll also noted
the irony of the inaccessibility of the House’s podium to congressional
staff members with disabilities.)
"I found Congress to be a very hospitable place.
That surprised me a bit," he said. "In the hallways I sensed
real collegiality and real concern for the nation — across the aisle.
It wasn’t just party battling that we see all the time."
Before his presentation, Carroll had to submit the prayer
for approval by the Chaplain’s office to be sure it adhered to certain
guidelines.
Prayer leaders are guided "to encourage the congressmen
and women and also to remember that the nation is under God. They encourage
you not to delve into foreign policy or domestic policy," Carroll
said, adding that this was challenging since he and his wife have been
"rather outspoken" against the prospect of war with Iraq.
"As I prepared the prayer, I felt God gave me the
things that I needed to say at a time like this, and I tried to pray
faithfully in that direction," he said.
A Congregation Gives Back
The event was one of several ways in which church members
have shown their appreciation and empathy to the Carrolls as Tracy battles
ALS.
He now wears leg braces and uses a cane when he walks.
His hands and arms have been weakened, and his breathing is affected
by the disease, he said.
"The wheelchair is coming, I can see it,"
said Carroll, whose father and grandfather died of ALS.
Just after they returned from Washington, the Carrolls
moved into a home that would accommodate a wheelchair since the parsonage
wasn’t accessible.
They purchased the home with the help of $50,000 in
contributions from members of the church and the community (Camdenton
is a small resort town of about 3,000 on the Lake of the Ozarks.)
The community has also donated a voice-activated computer,
and funds so the family can take a vacation before he needs to use a
wheelchair full time. Friends are putting together a care team for the
time when his medical needs become more complex.
"There are men in the church that literally help
me get upstairs, and the church has been so wonderful in moving us,"
Carroll said. At some point Tracy will take disability leave, and Colleen
will continue as pastor.
"I’m very humbled by all
the honors I’ve received, and I’m overwhelmed by the reciprocal love
that I’ve received from the community and the church that we serve here.
It’s just a wonderful group of people," Carroll said.
Contribution to Research
Carroll is also committed to doing his part for research
seeking a cure for ALS. He participates in an MDA genetic study of ALS
at Northwestern University and in a double-blind study of the drug Celebrex
at the MDA/ALS Center at Washington University School of Medicine in
St. Louis.
Despite a three-hour drive each month to St. Louis,
participating in the study helps keep the Carrolls from feeling "detached"
because there are few treatment options for ALS, Colleen Carroll said.
"Through the monthly visits
because of the study, we still feel very connected and very informed
and, in fact, cared for," she said.
Meantime, the Carroll family — which includes Nathaniel,
17, and Tabitha, 13 — is recording a music CD of faith-based songs.
While Tracy Carroll continues to care for his congregation,
he’s deeply honored that his congregation is now taking care of him
and his family — so much that he doesn’t dwell on having ALS.

ALS Doesn’t Masquerade As Lyme Disease,
Experts Say
Recent items in The ALS Digest, an online publication,
have suggested that the tick-borne, bacterial infection known as Lyme
disease can mimic ALS and that new tests can tell the difference between
these conditions with certainty.
But can this infectious disease actually be confused
with ALS? And, if you do get a positive result on a Lyme test, can you
be assured you don’t have ALS?
Not likely, experts say.
ALS involves dysfunction of upper motor neurons (the
nerve cells that run from the brain to the spinal cord) and lower motor
neurons (the nerve cells that go to muscles). This dysfunction is detected
by physical exam and electrical testing.
"The selective involvement
of upper and lower motor neurons, sparing other nervous system structures,
is the hallmark of ALS," says neurologist David Chad, who directs
the MDA clinic at the University of Massachusetts in Worcester, in the
heart of Lyme disease country. "That’s not typical of the neurological
complications of Lyme disease."
A red rash with a clear center,
resembling a "bull’s eye," is common with Lyme disease.
It has a set of symptoms different from those of ALS.
|
Lyme, Chad notes, "has the tempo of an infectious
disease. Although there are chronic forms, Lyme disease usually presents
as an infection, with a rash, followed by fever, headache, limb pain
and malaise."
In contrast, he says, ALS, in the vast majority of cases,
"is painless, comes on over months, and is not accompanied by a
systemic component."
Allen Steere, a rheumatologist at Massachusetts General
Hospital in Boston and an expert in Lyme disease, says a new blood test
for Lyme, known as the VlsE, isn’t any better than slightly older tests
at detecting Lyme disease in someone who is far enough into it to have
neurologic symptoms.
There are "false positive" results with Lyme
disease tests, Steere says, because they aren’t completely specific
for the disease. Newer tests may even show more false positives, he
says, than the testing procedure now recommended by the Centers for
Disease Control and Prevention.
Only once in his long career has Chad ever found it
advisable to treat a patient for Lyme disease when he thought the problem
was much more likely to be ALS. That, he says, was a special case, in
which the Lyme disease treatment proved essential for the family’s peace
of mind.

Infection Derails Test of ‘Brain
Communicator’ in Activist Jayne
by Christina
Medvescek
David
Jayne, the Georgia man with ALS who spearheaded the fight against the
Medicare homebound restriction for people receiving home health care,
has been leading a different kind of fight against being locked in by
paralysis from ALS.
Jayne, 41, underwent surgery at Gwinnett Medical Center
in Duluth, Ga., in October to have an experimental Brain Communicator
implanted in his brain. He hoped the device would allow him to control
his personal computer via his thoughts.
The revolutionary device, created by Neural Signals
of Atlanta, uses implanted neurotrophic electrodes to detect brain activity
and translate it into commands that control computer software.
David Jayne, seen here preparing
to fly to Washington last year, hopes to try the Brain Communicator
again.
|
Although the electrodes appeared to be transmitting,
Jayne never had a chance to learn to use them to operate his computer.
His scalp incision refused to heal over the accompanying hardware, putting
him at risk for serious infection. The hardware was removed in mid-January,
but the electrodes were left in place.
Jayne says he’s regained most of his strength and endurance
since the surgery, and still has partial use of two fingers, as well
as most of his facial muscles. He’s now using another Neural Signals
product, the Muscle Communicator, which allows a user to operate a computer
mouse by means of extremely minor muscle movement from any part of the
body.
Jayne hopes to have the Brain Communicator hardware
reinstalled once his scalp has fully healed.
"What have I got to lose?" he says. "ALS
will soon paralyze me totally. I have children to raise and work to
do."
Jayne’s surgery was paid for by the National Institutes
of Health because of its experimental nature. Neural Signals is developing
its technology in partnership with several entities, including the National
Institute of Neurological Disorders and Stroke, five universities and
the Veterans Administration. The company can be reached via www.neuralsignals.com or (404) 872-5757.
Jayne, who heads the National Coalition to Amend the
Medicare Homebound Restriction (www.amendhomeboundpolicy.homestead.com),
invites people to contact him about the new devices at djayne23@
