Chronic Fatigue: Doctors Find Some Clues to the Mystery
New York Times Service
New York - Researchers at three medical centers in New Jersey, Massachusetts
and Colorado are conducting sophisticated tests on patients with chronic
fatigue syndrome and comparing notes in the first consistent, multidisciplinary
approach intended to get to the bottom of the disorder.
The syndrome, which begins with flu-like symptoms and can lead to exhaustion
lasting for years, remains a profound mystery, said Dr. Stephen E. Straus,
chief of the medical virology center at the National Institute of Allergy
an Infectious Diseases in Bethesda, Maryland, the agency financing the
$3 million research program.
"Doctors do not know the molecular basis of fatigue in anyone, much less a
person with chronic problems," Dr. Straus said. "When people say they feel
tired all the time and their doctors can't find anything wrong with them,
they're told the problem is in their heads."
But many leading researchers are now convinced that patients are telling the
truth, Dr. Straus said. One compelling reason stems from recent research
on cytokines, cells of the human immune systemthat have been isolated and
turned into drugs to fight cancer and other diseases. When healthy volunteers
are injected with cytokines, Dr. Straus said, they feel awful and exhausted,
exactly as chronic fatigue patients do.
A leading hypothesis among researchers is that chronic fatigue results from
abnormally activated cytokines. "We can find plenty of things wrong with
these patients," he said, including depressed numbers of natural killer cells,
elevated antibodies to childhood viruses and signs of hormone complexes that
depress the immune system. "But we don't know what to relate these changes to"
or how they compare with healthy people and patients with other diseases that
involve fatigue.
At the Chronic Fatigue Center in the Veterans Affairs Hospital of East Orange,
New Jersey, a team led by Dr. Benjamin Natelson is looking for ways to
diagnose the disorder in patients. "If most doctors can't find an abnormality
in a lab test, they think it's the patient's fault," Dr. Natelson said, "One
of the biggest problems with chronic fatigue has been physician arrogance."
The New Jersey center has found a possible way to diagnose chronic fatigue
patients.
Sue Ann Sisto, a physical therapist at the center, noticed that patients
breathe from the upper body, rather than from the belly and abdomen as most
people do. Further testing showed that chronic fatigue patients have abnormal
vagal tone, meaning the major nerve that syncopates their breathing and heart
rate is out of sync. Their hearts are not speeding up and slowing down at a
normal pace.
"This is a solid piece of evidence that something is going on with these
patients," Dr. Natelson said. "Their bodies seem to be conserving energy is
strange ways."
At the Chronic Fatigue Center of Brigham and Women's Hospital in Boston,
Dr. Anthony Komaroff is focusing on the cytokine hypothesis. One idea is
that the disease stems from the reactivation of childhood viruses.
When any virus proliferates, the body responds by releasing a torrent of
cytokines, cells that amplify the immune system and wage war against the
invading agent, Dr. Komaroff said. "We used to think you felt terrible
because the virus was attacking your cells," he said. "But that's not true.
You feel terrible because your body is responding and you are caught in the
crossfire. As cytokines hit target, they also hit you."
During the attack people feel exhausted and conserve energy by crawling into
bed, Dr. Komaroff said. Meanwhile, the cytokines alter liver metabolism and
lterally break down human muscles to obtain protein.
"Recycling your own body is more efficient than getting new food." he said.
"You go to sleep. The battle rages. Finally the immune system clears the
body of the virus. The attack is shut off."
In chronic fatigue patients, this does not happen, Dr. Komaroff said. "You
are in permanent crossfire," he said, "perhaps because the immune system
cannot clear the virus. Maybe it is a latent virusthat shows just enough
of itself to raise an attack but is hiding so well, the body can't kill it."
Cytokines are very difficult to measure, Dr Komaroff said. They are
short-lived, are made in many tissues and no one understands their natural
balance.
