Condition of 'pig-brain disease' patients has improved

The condition of a number of US patients, suffering from a disease related to pig brains, appears to have improved over the last year.

This is the result of a research, scheduled to be presented at the American Academy of Neurology's annual meeting in Seattle in late April.

More than a year ago, workers at pork processing plants in two US states developed pain, fatigue, weakness, numbness and tingling in their arms and legs. Remarkably, all of them worked in or near areas where the brains of pigs were extracted with compressed air, a practice since discontinued.

The research looked at 24 of the affected workers and found that all had improved to some degree by taking immune suppressants, such as steroids, or by simply avoiding further exposure to pig brains.

The patients, however, were not symptom-free, and many still had mild pain.

The condition has been identified as a new disorder with an underlying auto-immune basis because all of the workers were found to have a never-before-seen antibody.

"There are other autoimmune disorders where the trigger is not known, so this case with a known trigger could provide us with an opportunity to understand how an antigen can trigger the body's immune system to produce disease," study author Dr P. James B. Dyck, of the Mayo Clinic in Rochester, MN, USA, said in a news release from the meeting's sponsor.
