American scientists have found that probiotics based on the bacteria Lactobacilli and Bifidobacteria alleviate the symptoms of hay fever, and significantly improve the quality of life of allergy sufferers during the flowering season..

A new treatment for allergic rhinoconjunctivitis is reported in the American Journal of Clinical Nutrition by study author Jennifer Dennis of the Department of Dietetics and Human Nutrition at the University of Florida.

Hay fever, or seasonal allergic rhinoconjunctivitis, is a common disease caused by pollen.

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

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

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

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

Combination of probiotics improves quality of life for allergies.

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

According to Dr. Dennis, human-friendly lactobacilli and bifidobacteria support not only the health of the digestive tract, but also the balance within our immune system..

For the last project, probiotic combinations were used containing the following bacteria species: Lactobacillus gasseri, Bifidobacterium bifidum and Bifidobacterium longum. They are often found in probiotics to treat intestinal dysbiosis.

The trial involved 173 healthy adult volunteers with mild to moderate seasonal allergies.. The subjects were randomly divided into two groups: the first received a probiotic capsule twice daily, and the second a placebo..

During the 8-week study, participants were prohibited from taking any anti-allergic drugs.

The experiment took place during the flowering season.

Subjects who took lactobacilli and bifidobacteria reported significant improvement in quality of life and relief of rhinoconjunctivitis symptoms. Indicators monitored according to participants' words during weekly telephone conversations.

Probiotics Affect Regulatory T Cells.

Although it will take more effort to explain the probiotic phenomenon, scientists are now talking about the direct effect of beneficial bacteria on immunity.. Probiotics stimulate the so-called regulatory T cells, which are designed to control the strength and duration of any immune response.

“Not all probiotics are good for allergies, but these are really good.. I think people with mild seasonal allergies should try, ”says Dr. Dennis.
