Early encounter to bacteria prevents kids from allergy risk in later life

Infants who encounter a wide range of bacteria are at less risk of increasing allergic disease later in life, according to a new study from the University of Copenhagen the figure over sensitivity diseases, or allergies, has been on the raise in recent decades.

Now researchers at the Dansk BorneAstma Center University of Copenhagen, are at last able to partly explain the reasons,“In our study of over 400 children we experiential a direct link between the number of different bacteria in their rectums and the risk of increase of allergic disease later in life,” said Professor Hans Bisgaard, advisor at Gentofte Hospital, head of the Copenhagen Prospective Studies on Asthma in Childhood.

“Reduced diversity of the intestinal microbiota through infancy was associated with increased risk of allergic disease at school age, he continues but if there was significant diversity, the risk was reduced, and the better the variation, the lower the risk.

Surge in allergic diseases in India: WAO

Growing industrialisation and fast changing biodiversity coupled with sedentary lifestyles are cause a surge in allergic diseases, especially between children in the country, the World Allergy Organisation (WAO) has warned.

Currently, about 20 to 30 per cent of people in India are having one or additional allergic diseases and their prevalence is rising dramatically, the WAO said, the diseases integrated asthma, rhinitis, anaphylaxis, food and drug allergy, insect allergy, eczema and urticaria (hives) and angioedema, it said.

The prevalence of asthma and rhinitis two major form of allergies was one and 10 percent likewise in 1964 in the country but new data shows that about 14 per cent people now have asthma, while over 20 per cent are pain from allergic rhinitis (AR) which results from an IgE-mediated inflammation of the nasal mucosa.

Kids' Eczema, Hay Fever Linked to Allergic Asthma Later

New research finds that adults who suffered from eczema as children especially if they also had hay fever are nine times more likely to have allergic asthma when they're in their 40s. The findings are based on about 1,400 adults who have been followed for five decades as part of Australia's Tasmanian Longitudinal Health Study. The study participants were assessed in 1968, when they were 7 years old, and then again in 2004 when they were about 44 years of age.

"In this study we see that childhood eczema, particularly when hay fever also occurs, is a very strong predictor of who will suffer from allergic asthma in adult life," lead study author Pamela Martin, a University of Melbourne graduate student at the Murdoch Childrens Research Institute, said in a university news release. "The implications of this study are that prevention and rigorous treatment of childhood eczema and hay fever may prevent the persistence and development of asthma."

Allergic asthma is airway obstruction and inflammation that's triggered by inhaled allergens such as dust mites, pet dander, pollen and mold. According to Martin, the study is the first to examine childhood eczema and hay fever and their connection to allergic versus nonallergic asthma. The linkage between childhood illnesses and adult asthma is called the "atopic march." "If successful strategies to stop the 'atopic march' are identified, this could ultimately save lives and health care costs related to asthma management and treatment," Shyamali Dharmage, principal investigator of the Tasmanian Longitudinal Health Study.
