American scientists have found that probiotics based on bacteria Lactobacilli and Bifidobacteria alleviate the symptoms of hay fever, and significantly improve the quality of life of allergic people during the flowering season, according to the Internet edition for girls and women from 14 to 35 years old Pannochka. net A new method for treating allergic rhinoconjunctivitis in the pages of the American Journal of Clinical Nutrition is reported by study author Jennifer Dennis from the Department of Dietetics and Nutrition of the University of Florida.

Hay fever, or seasonal allergic rhinoconjunctivitis - a common disease, provoked by pollen of plants.

It should be said that hay, contrary to the historical name, is not an important trigger for the disease.

Redness of the eyes, runny nose, dermatitis and violation of general well-being become the first spring swallows for millions of people with seasonal allergies. Depending on the individual sensitivity to these or other plants, hay fever can be exacerbated in the spring, during the summer or even in the early autumn.

Until now, the main drugs for hay fever remained antihistamines, decongestants and nasal corticosteroids. However, each of them has side effects, and not all patients can use them.

Probiotics (useful bacteria) offered by scientists are well tolerated, have no side effects and can be recommended as an alternative treatment.

Combination of probiotics improves the quality of life for allergies.

Studies of past years have suggested the effectiveness of probiotics in seasonal allergies, but the results were very different depending on the strains of bacteria used. Now, it seems, scientists have found the best combination.

According to Dr. Dennis, "friendly" to the human body lactobacillus and bifidobacteria support not only the health of the digestive tract, but also the balance inside our immune system.

For the last project, combinations of probiotics were used, containing the following bacterial species: Lactobacillus gasseri, Bifidobacterium bifidum and Bifidobacterium longum. They are often included in the composition of probiotics for the treatment of intestinal dysbiosis.

The trial involved 173 healthy adult volunteers with mild to moderate manifestations of seasonal allergies. Subjects were randomly divided into two groups: the first twice a day received a probiotic in capsules, and the second - a placebo.

During the 8-week study participants were forbidden to take any antiallergic drugs.

The experiment was for the flowering season.

Subjects who took lactobacilli and bifidobacteria noted a significant improvement in the quality of life and alleviation of symptoms of rhinoconjunctivitis. The indicators were monitored according to the participants' words in weekly telephone conversations.

Probiotics affect regulatory T cells.

Although additional efforts will be required to explain the phenomenon of probiotics, scientists today talk about the direct influence of beneficial bacteria on immunity. Probiotics stimulate so-called regulatory T cells, which are designed to control the strength and duration of any immune response.

"Not all probiotics are useful for allergies, but these are really good. I think that people with a mild seasonal allergy should try it, "says Dr. Dennis.
