Blood test for irritable bowel syndrome

Irritable bowel in some people can be detected using one of two blood tests developed by Cedars-Sinai Medical Center in Los Angeles, reports CBS News on its website.

Irritable bowel syndrome is one of the most difficult conditions to diagnose. Many patients suffer from abdominal pain and bowel movements, the causes of which cannot be determined. Some are even accused of hysteria or neurosis and referred to a psychiatrist.

In some patients, the causes of the disease affecting both the small and large intestines, however, are physiological, not mental. According to one theory, it may be caused by an autoimmune reaction in which immune cells attack their own tissues in the digestive tract.

It is a post-infectious form of disease caused by food poisoning when pathogenic bacteria that produce toxins enter the intestines. They are removed from the body, but antibodies that destroy the cells of the small and large intestines are still produced. This results in ailments typical of irritable bowel syndrome.

This mechanism of the disease was used with his team, Dr. Mark Pimentel of Cedars-Sinai Medical Center in Los Angeles. Two tests developed by him detect antibodies in the blood that are responsible for the autoimmune reaction.

New York University Medical University Gastrologist Dr. Jon LaPook says the new tests will be able to detect irritable bowel syndrome in at most 44 percent. sick. These are patients in whom an autoimmune reaction is the cause of irritable bowel syndrome. Others who test negative may also have the condition, but on a different basis.

In the United States, from 25 million to as much as 45 million people can suffer from irritable bowel syndrome. In Poland, these ailments are felt from 10 to 20 percent. adult population.
