Stomach Virus Could Trigger CFS
Enterovirus Found in Many Chronic Fatigue Syndrome Sufferers
Other Conditions Lead to CFS continued...
Specimens from 165 CFS patients and 34 people without the disorder were
tested, and Chia found evidence of possible chronic infection in 82% of the CFS
patients and 20% of the well patients.
Though the findings must be verified, Chia says they suggest a strong
association between possible chronic infection with enterovirus and chronic
“Although finding a chronic infection in the stomach may not directly prove
a similar infection in the brain, muscle, or heart, it opens up a new direction
in the research for this elusive disease,” he writes in the latest online
edition of the Journal of Clinical Pathology.
Specifically, he says endoscopy could prove to be a relatively simple test
to confirm persistence of enterovirus infection in CFS patients, as well as a
way of following responses to antiviral treatments.
Chronic Fatigue and Immune Disorder Syndrome Association of America
president Kimberly McCleary says CFS has turned out to be a much more complex
illness than anyone could have predicted.
“It is unlikely that we are ever going to find just one bug to explain all
cases of CFS,” she says.
She points to recent research from Australia finding that three very
different infections result in a CFS-like condition in 12% of cases.
“It is quite possible that both an infectious agent and the [body’s]
response to that agent act as triggers,” she says.
