New study seeks to prove treatment benefits of probiotic for grass pollen allergies

Berlin, 11 August 2022 – In a current study, scientists are investigating the benefits of a probiotic (a substance containing lactic acid bacteria to strengthen the intestinal flora) in the treatment of allergic rhinoconjunctivitis caused by grass pollen. Particular to this medically supervised study is the specially constructed pollen chamber (exposure chamber), in which the study subjects come into contact with grass pollen using a unique procedure. The supplement is taken for three weeks between two exposure chamber sessions.


Previous studies have already shown the benefits of probiotics (selected strains of bacteria) in relieving the symptoms of grass pollen allergy. Gut bacteria can thus have a more positive influence on people with allergies than was thought just a few decades ago.


“The rise in pollen allergies in recent decades has been attributed to reduced contact, even in childhood, with certain microorganisms that are actually supposed to protect against allergic diseases by supporting the development of the immune system,” says Prof. Dr. med. Dr. h.c. Torsten Zuberbier, Chairman of the European Centre for Allergy Research Foundation (ECARF). “Our current understanding shows that microbial contacts that protect against allergies are almost exclusively brought about by diet, avoidance of antibiotics and special lifestyles. Natural childbirth and breastfeeding, increased social contact and outdoor activities also help to restore the microbiome and may reduce the risk of allergic diseases.”


More subjects with a grass pollen allergy can still participate in the study. More information is available at www.ecarf-institute.org
